In other words, the default refspec is "+refs/heads/*:refs/remotes/REPOSITORYNAME/*" where REPOSITORYNAME is the value you specify in the above "name of repository" textbox.
When do you want to modify this value? A good example is when you want to just retrieve one branch. For example, +refs/heads/master:refs/remotes/origin/master would only retrieve the master branch and nothing else.
See the term definition in Git user manual for more details.

(powder / crystals) |
| T+ 1:00 |

(powder / crystals) |
I received my 125mg. of 2C-T-7 from my buddy the previous Thursday night, but held off on using it because I wanted to trip at the museum with a friend on Saturday, but she fell ill and couldnít make the journey. So as I sat at home Monday night curious as hell as to what this chemical would do to me, I decided to give it a whirl, I notified my cousin I would be taking the T7, so if I call him in a craze, he would know whatís going on.
6:45 pm. - ~7mg. 2c-t-7 insulfated, mixed in 1:2 with confectioners sugar, hoped it would ease the burn that I have heard so much about. Didnít work, my whole face felt like it was scorched with a flamethrower. My right nostril felt like there were 1000 suns burning inside of it, I just wanted to rip it off. Then came the waterworks, I couldnít stop the tears. This lasted for about 10 minutes.  Nothing special seems to be happening as of now, colors seem to be a little more vibrant and warm, and I feel very euphoric, but Iím looking for some visuals, so I decide to bump ~2mg. more. No pain this time, thank god.
8:00 pm. I decide to hop into bed and listen to some music. I turn all the lights off except for a candle next to my bed and throw on some Bjork. Iím in a very happy place at this point, very euphoric, I close my eyes and begin to see interesting visuals, not quite true CEVís like I have experienced with 5-MeO-DiPT, but sort of closed eye thought/visuals, very weird. I would begin to think of something and it would come alive inside my head. The music I was listening to was very outworldly and brought about many interesting thoughts into my head. The most vivid one I remember is when I began to think about a water snake, and it all of a sudden came alive inside my head and began to slither around, and then just bolted out at me and showed its enormous fangs to me, but to my surprise I was not scared at all. I just lay there and smiled.
8:30 pm. I decide to check around for OEVís, so I head downstairs where my sister and two dogs are, I go lay down on the kitchen floor with my older dog Daphne, and I look into her eyes, we just sat there looking at each other for about 5 minutes, it was quite serene.  This was an interesting experience since she can rarely stay still on the couch with me for more than 5 minutes at a time, itís as if there was a special connection.
8:50 pm. I head back up stairs and throw on the matrix. I watch the first 30 minutes or so, and I seemed to understand what ďThe MatrixĒ actually is, considering this movie is one of my favorites and I have seen it 10 or more times, it was a little weird actually getting a different message from it.
9:30 pm. I head into the bathroom to take a leak, as I walk past the mirror I smile, I remember how the mirror always seems to be my favorite trip toy, so I quickly relieve myself and head to the mirror, I stare at my face, and after about 20 seconds my faces begins to swirl around and move in and out, the colors of my face and my surrounding are very vivid and warm, lots of oranges and light reds. I look away and look back at the mirror, but I am disappointed that I have to concentrate so hard to get visuals.
9:45 pm. Back to my bedroom, the trip seems to do be almost dead I assume, but I still feel very warm and cozy inside. I hop online and talk to some friends and respond to some e-mails. I notice every once in a while the computer screen seems to grow and shrink in size, and my room seems to take short little breaths every once in a while. My room is painted sunshine yellow, so everything has a very warm aura to it.
10:30 pm. My buddy J calls to see how Iím doing as my trip is basically dead. We talk for about an hour, I head back to my room and hop into bed and watch letterman, he is extremely funny tonight for some reason, Iím sure the T7 helped.
Afterthoughts Ė I think that this was too low of a dose for me, but I also think that I may have eaten too much before I tripped, I had a big salad at like 5:30 pm. Next time I am going to try 20mg. orally with an empty stomach. I could tell that this chemical has much potential, the body feeling that it gives off is extraordinary, and the hues and auraís of color it gives off and compliments is fantastic. I was hoping for more OEVís, but we canít all be happy!

Hello subscriber! It’s time for your weekly recap of what happened in React Core and React DOM.
🏞 New Server Rendering Infrastructure: Fizz
Work on the new Server Rendering Infrastructure Fizz has begun. The new renderer features built in support for Suspense and utilizes node streams. Check out Andrew’s talk at ZEIT earlier this year for a glimpse of what the new server renderer will be able to do.
You can now follow along as the team is preparing the React DOM code for the upcoming React Fire updates. The changes currently include a new and lighter weight event system.
Thanks to the help of V8 team members, the React team was able to find and fix a significant performance cliff during the commit phase when the React profiler is enabled.
New contributors land their first PR in the react, devtools, or reactjs.org repositories every week. A special round of applause for this week goes to:


Weather service to change how flash flood alerts get sent to your phone
by HNN StaffHONOLULU, Hawaii (HawaiiNewsNow) - When a flash flood warning is issued for your area, you probably get a blaring alert on your mobile phone.
Those so-called wireless emergency alerts are seen as potential life-savers. But nationally, they’ve also been the source of some frustration.
The concern: The warnings are sent too frequently and to lots of people who are unlikely to be affected.
In a bid to address those issues, the National Weather Service will debut its new “impact-based” flash flood warning format in Honolulu this month, changing the alerts sent to your phone.
The new system, set to launch next month, is aimed at recognizing that not all flash flood warnings are the same ― and that only more severe flooding should warrant an alert on your phone.
So going forward, most flash flood warnings won’t trigger a mobile phone alert.
Instead, alerts will only be sent in the case of “considerable” or “catastrophic" flash flooding.
A “considerable” flash flood warning will be used rarely, and only when there are indications flash flooding is capable of unusual severity or urgent action is needed to protect lives and property.

FEMA helped contribute to the new format, noting resident complaints over wireless emergency alerts for flash flooding with perceived little impact.
The National Weather Service issues more than 4,000 flash flood warning each year.
Meanwhile, the service is also seeking to including more information in its flooding warning, with a source for the information and a brief description of the potential impact.
The weather service said third-party vendors, such as weather apps, will be able to identify and extract the “emergency” language in the flash flood warnings and send that information to the public.

"OTO" means "sound" in Japanese. "OTOduino" is a visualized sound modem terminal application for iPhone. You can monitor and control Arduino(TM) digital and analog ports status by connecting your Arduino to iPhone earphone jack as following:
Both "OTOduino" (repository https://github.com/reinforce-lab/OTOduino) project and a software modem project "OTO-plug" (repository https://github.com/reinforce-lab/OTO-plug) which "OTOduino" uses are open-source projects released under MIT license. These projects have been developed by an freelance engineer Akihiro UEHARA, REINFORCE Lab (http://www.reinforce-lab.com/, web site is written in Japanese) who also provides iPhone software design services.
You need an interface circuit to use OTOduino.
However the interface circuit for Arduino is going to be released at the end of March,
it is very simple that You can make your own one.
Its circuit diagram is as following:
Any kind of capacitores can be used for C1 and C2.
Earphone jack left channel must be connected to the Arduino.OTOduino app only uses headset left channels to transmit data to Arduino. Right channel is mute.
First SoftwareModem library should be added to your local disk. Make a "SoftwareModem" directory in your Arduino libraries directory (~/Document/Arduino/libraries/ on Mac OS), and then download source codes SoftwareModem.cpp and SoftwareModem.h from the repository https://github.com/reinforce-lab/OTOduino/tree/master/OTO-plug/src/arduino/libraries/SoftwareModem/.
Second download a sketch and upload it. Make a "OTOduinoSImpleClient" directory and download source codes OTOduinoSimpleClient.pde and OTOduinoTypes.h from the repository https://github.com/reinforce-lab/OTOduino/tree/master/src/arduino/OTOduinoSimpleClient. Now you can open the OTOduinoSimpleClient sketch and verify/upload it to your Arduino.
When you plug an audio jack to iPhone, OTOduino connection icon (at the left lower of a screen) changes "Disconnected" to "Connected". If it does not changes to "Connected", check the warning message shown the right side of the icon. In the most cases, you should set the output volume at the maximum.
You can monitor voltage of Arduino analog ports. You can toggle enable/disable state of the analog panels (placed at the left of the screen) by touching them. To monitor digital ports, first touch a small icon of digital panels to change it to "in" icon. Then right button shows the current digital port value (high or low). To output signal from a digital port, touch a small icon and change it to "out" icon. Then you can toggle high/low status of the digital port by right button touch.

Hi all!
I just wanted to announce the availability of a distributed search engine for
Alice with Gecode. It was written by Didier (mailto:botlan at ps.uni-sb.de),
inspired by Christian's thesis, and can use my explorer clone for Alice for
visualisation. You can have a look at it, it's in the Alice cvs under
lib/constraints/distribution.

Gilt at the Fashion Hackathon
Hello there!
I’m Miguel Fajardo, an engineer at Gilt. I want to share a great experience I had with fellow Gilt engineers Jose Sanchez and Patrick Losco at the recent Fashion Hack during New York Fashion Week.
Hearst Corporation hosted the event in their New York City headquarters, the Hearst Tower. The building is easily identified by its diamond-patterned façade. Many other companies co-sponsored the event, including Microsoft, Spotify, Okta, HTC, and of course, Gilt.
The two-day event kicked off on Saturday morning in the auditorium where Hearst explained the rules of the competition. The goal was to build a web or mobile application that would interact with the APIs of some of the sponsoring companies, that included Gilt.
As one of the companies exposing the APIs to be used as part of the competition, we presented our developer portal and showed some examples to illustrate how to use the Gilt API. Anyone can query our systems to retrieve information about current or future sales, including what products will be included and a ton of info about them (price, current availablity, checkout URL, etc). If you are interested, you can find more info in our developer portal.
Here you can see the team once dinner was served at 7pm:
From left to right: Miguel, Jose, Patrick, and Dalia (she joined our team as application designer and front end developer).
Our idea was to use a city selected by the user and the current local weather to show trends in the form of relevant clothing and accessories from Hearst media. When the user chooses an image, the application recommends similar products available on Gilt. We built it using the Play framework with Java and Twitter Bootstrap.
By midnight, we had the retrieval of content from the APIs completed and started focusing on the front end. Time flies in this kind of event, where you are trying to design and build an entire application in such a short period of time!
We had all major functionality wired up by dawn, and then it was a matter of improving the user interface and optimizing performance. We improved the algorithm to select what images from Hearst to show and how to link these to the Gilt items on sale. We decided to fetch the weather at runtime, but cached other API calls that were taking up to a minute. The submission deadline was Sunday at 1pm and we made it just in time. There was no time to rest before all the teams presented their work.
The presentations took place on the 44th floor of the amazing Hearst Tower.
The views were stunning, especially with fresh snow from the previous day’s blizzard covering the city.
Our presentation went smoothly and we even appeared in a tweet from Hearst president David Carey.
In the end we got a special mention as one of the top 5 applications.
Jose was already asleep by the time we got to the prizes.
The Hearst Fashion Hack was a great experience. Not only did we learn a lot about the APIs, but we had a lot of fun together. You can view a demonstration of the application in this video.
Hope you enjoyed the post!


package main
import "fmt"
func main() {
var arr1 [2][2]int = [2][2]int{
{5, 8},
{3, 4},
}
var arr2 [2][2]int = [2][2]int{
{5, 6},
{7, 8},
}
fmt.Println("Element in first array =", arr1)
fmt.Println("Element in second array =", arr2)
var sub [2][2]int
for i := 0; i < 2; i++ {
for j := 0; j < 2; j++ {
mul[i][j] = arr1[i][j] - arr2[i][j]
}
}
fmt.Println("Subtraction of first and second array element`s =", mul)
}
Element in first array = [[5 8] [3 4]]
Element in second array = [[5 6] [7 8]]
Subtraction of first and second array element`s = [[0 2] [-4 -4]]
In this program, as an output we compute the Subtraction operation on two array:
arr1 and arr2;
And then store the result in sub array.
After that we display the element`s of arr1, arr2 and sub array.


Configuring Storage (IPFS)¶
Embark will check your prefered storage configuration in the file config/storage.json
. This file will contain the prefered configuration for each environment. With default
being the configuration fields that applies to every environment. Each of those can be individually overriden in a per environment basis.
e.g :
{
"default": {
"enabled": true,
"ipfs_bin": "ipfs",
"provider": "ipfs",
"available_providers": ["ipfs"],
"host": "localhost",
"port": 5001
},
"development": {
"enabled": true,
"provider": "ipfs",
"host": "localhost",
"port": 5001
}
}
- options available:
enabled
(boolean: true/false) to enable or completly disable storage supportipfs_bin
(string) name or desired path to the ipfs binaryprovider
(string: “ipfs”) desired provider to automatically connect to on the dapp. e.g in the example above, seting this to"ipfs"
will automaticaly addEmbarkJS.setProvider('ipfs', {server: 'localhost', 5001})
to the generated codeavailable_providers
(array: [“ipfs”]) list of storages to be supported on the dapp. This will affect what’s available with the EmbarkJS library on the dapp.host
andport
of the ipfs node to connect to.


Importing Data From Tables
Integrating Data Into String Networks
Here are some common automation workflows. Pick one that is similar to the type of data you work with. Follow the steps to learn about package functions.
Ask questions if anything is unclear!
Any questions?


This quickstart demonstrates using Firebase SDK for Cloud Functions setup with a Cloud Storage trigger.
This sample automatically generates thumbnails for images that are uploaded to Cloud Storage.
See file functions/index.js for the thumbnail generation code.
The thumbnail generation is performed using ImageMagick which is installed
by default on all Cloud Functions instances. This is a CLI so we execute
the command from node using the
child-process-promise
package. The image is first downloaded locally from the Cloud Storage
bucket to the tmp
folder using the
google-cloud
SDK.
The dependencies are listed in functions/package.json.
The function triggers on upload of any file to your Firebase project’s default Cloud Storage bucket.
To deploy and test the sample:
git clone https://github.com/firebase/functions-samples
cd functions-samples/quickstarts/thumbnails
firebase use --add
and select your Firebase project
firebase deploy
thumb_
prefix will be created in the same folder (make sure
you refresh the UI to see the new file).
We’d love that you contribute to the project. Before doing so please read our Contributor guide.

Machine Learning and Multiagent Systems: from robot soccer to autonomous traffic
|
|
The Learning Agents Research Group at UT Austin uses robot soccer to study Artificial Intelligence (AI) and Robotics. Our research focuses on enabling autonomous Aibo four-legged robots to improve their playing ability from experience (machine learning), and to interact with one another, both collaboratively and adversarially (multiagent systems). Our robots function completely autonomously: they sense their environment; engage in high-level cognitive decision-making; and then execute their actions in the environment. This talk provides an overview of our robot soccer research, and presents how it relates to autonomous bidding agents, autonomic coputing, and traffic management. |

public class DateTools extends Object
This class also helps you to limit the resolution of your dates. Do not save dates with a finer resolution than you really need, as then RangeQuery and PrefixQuery will require more memory and become slower.
Compared to
DateField
the strings generated by the methods
in this class take slightly more space, unless your selected resolution
is set to
Resolution.DAY
or lower.
Another approach is
NumericUtils
, which provides
a sortable binary representation (prefix encoded) of numeric values, which
date/time are.
For indexing a
Date
or
Calendar
, just get the unix timestamp as
long
using
Date.getTime()
or
Calendar.getTimeInMillis()
and
index this as a numeric value with
NumericField
and use
NumericRangeQuery
to query it.

What is Lymann-\(\alpha\) Forest?
Ly-\(\alpha\) forest example of QSO 1422+2309 (top panel), the interpretation of it’s formation (middle panel), and a zoom of the spectra (bottom panel). From Springel et al. (2006), Figure 2
When we look at the spectra of a quasar, we will find an area with very dense absorption lines blueward to the Lymann-\(\alpha\) emission line wavelength. This area looks like the forest, so it is called “Lymann-\(\alpha\) Forest”. Ly-\(\alpha\) forest, combined with two other kinds of absorption line (broad and narrow absorption line), raised a debate on their origin. It turned out that broad lines are from quasars themselves, while narrow lines as well as Ly-\(\alpha\) forest come from absorption of galaxies and neutral hydrogen located in the line-of-sight between quasar and us.
Photons with a wavelength of 1216 Angstrom may be absorbed by neutral hydrogen cloud in the line-of-sight between quasar and us. Although the absorption will always happen in 1216 Angstrom, the spectra of quasar, because of the expansion of Universe, will not stay in the same place. As the photon going through Universe, its wavelength will increase, that is, the whole spectra will have a redshift while the Lymann-\(\alpha\) absorption is still in the same wavelength. Thus, those dense absorption forest are mainly caused by one absorption (some other lines such as Lymann-\(\beta\) will also cause a “forest”, but much weaker than Lymann-\(\alpha\)).
A clear interpretation video is presented here.
Why Ly-\(\alpha\) Forest can be used as Cosmological Tool?
Because the absorption which should be in the same wavelength now shifted to a wavelength range corresponding to quasar’s redshift, it maps the situation of neutral hydrogen between the redshifted Lymann-\(\alpha\) line of quasar and 1216 Angstrom, and we can derive the distribution from what we have observed in the telescopes.
Furthermore, simulation and measurement of Lymann-\(\alpha\) line’s broadening indicate that density of neutral hydrogen cloud is low, and their temperature is between \(10^4\) and \(2 \times 10^4\). Compared to gravity, pressure forces will be small, so the behavior of neutral hydrogen will basically be the same as dark matter. As a result, we can trace density distribution also from that of neutral hydrogen.
Last but not least, the relation between observed flux in a particular wavelength and density in that distance can be determined, both from a complex relation or a easier method (Gallerani et al. 2011, see next section)
In short, the reason Ly-\(\alpha\) forest can be used as cosmological tool is by measuring it, we can constrain some parameters of our modeled cosmology, or, in reverse, we can create the model Ly-\(\alpha\) forest and it looks like what we actually observed.
How to constrain the model of Cosmology using Ly-\(\alpha\) Forest?
To constrain the cosmological parameters, we must first translate observed spectra to density fluctuation. It can be done by directly derive the relation from physical image, or using a more practical way. Gallerani et al. 2011 described both methods and it is worth repeating this here.
Since distribution of neutral hydrogen cloud is not homogenous along line-of-sight (LOS) between quasar and us, we have to treat each wavelength, or distance separately. We first divide the LOS into \(N\) bins, then as the definition of optical depth, we have,
\[\frac{F(i)}{F_c} = e^{-\tau(i)}\]where \(\tau(i)\) is,
\[\tau(i) = cI_\alpha \frac{\Delta x}{1+z(i)} \sum_{j=1}^{N} n_\mathrm{HI}(j)\Phi_\alpha[v_H(i) - v_H(j)]\]here \(c\) is light speed, \(I_\alpha\) represent the cross-section of hydrogen, \(\Delta x\) is the bin length in comoving coordinate, \(\Phi_\alpha\) is Voigt profile and \(n_\mathrm{HI}\) is neutral hydrogen fraction.
Neutral hydrogen cloud is in a low-density situation, so it’s easily ionized. We can assume that the cloud is in the equilibrium of ionization and recombination, then \(n_\mathrm{HI}\) can be express as:
\[n_\mathrm{HI} \propto \frac{T_0\Delta(j)^{-0.7(\gamma-1)}}{\Gamma} n_0^2 [1+z(j)]^3 \Delta(j)^2 \propto \Delta(j)^\beta, 1.5 < \beta < 2.0\]where \(T_0\) is IGM temperature at mean density and redshift \(z(j)\), \(\gamma\) (slope of equation of state) indicate the reionization history of Universe, \(\Gamma\) represent the photoionization rate at given \(z(j)\), and \(\Delta(j)\) is the over density in a given \(j\). So we can see here \(\tau(i)\) is related to the property of hydrogen cloud, reionization history of Universe and profile of hydrogen absorption line (even if assume Gaussian, it still related to thermal state of the gas).
This is the reason stating direct derivation of flux-density relation is very complex; it convolutes too many factors that makes calculation impossible or losing accuracy if more assumptions are introduced. However, by using probability distribution function (PDF), this relation can be determined by computation.
Let us now consider the PDF of observed, or transmitted flux \(F\) as well as over density \(\delta\). Here it is assumed that an over density \(\delta_*\) is associated to a single value of \(F_*\), so from the conservation of probability, integral from \(0\) to \(F_*\) must be equal to integration from \(\Delta_*\) to \(\infty\), that is,
\[\int_0^{F_*} P_F dF = \int_{\Delta_*}^\infty P_\Delta d\Delta\]or vice versa,
\[\int_{F_*}^1 P_F dF = \int_0^{\Delta_*} P_\Delta d\Delta\]Of course, observation will always be accompanied by uncertainties, so when the flux is very close to 0 or 1 we cannot tell the small discrepancy from 0 or 1 is from absorption or error. To account for this, one maximum and minimum flux (\(F_\mathrm{max}, F_\mathrm{min}\)) and the corresponding minimum and maximum optical depth (\(\Delta_\mathrm{min}, \Delta_\mathrm{max}\)) is set as the boundary of the integral,
\[\int_{F_\mathrm{min}}^{F_*} P_F dF = \int_{\Delta_*}^{\Delta_\mathrm{max}} P_\Delta d\Delta\] \[\int_{F_*}^{F_\mathrm{max}} P_F dF = \int_{\Delta_\mathrm{min}}^{\Delta_*} P_\Delta d\Delta\]By solving these equations, we can get the relation of \(F\) and \(\Delta\), then convert the observed spectra to over density. Simulation have shown that after setting a set of parameters \((\beta, \Gamma, T_0, \gamma)\), both the spectra and distribution of over density can be recover well.
Top: Original spectra (black) of Ly-\(\alpha\) forest and synthetic spectra (red, blue and green) using different set of \((\Gamma, T_0, \gamma)\); bottom: same color for top but for distribution of overdensities. From Gallerani et al. 2011, Figure 3
So now we can determine a 1-dimentional density fluctuation long one LOS; this is far from enough to constrain the cosmological model. But if we have a large number of quasars spreading over a large area of celestial sphere, then it will be possible to achieve 3-D density field. Luckily, BOSS survey from SDSS provides this possibility.
Footprint of BOSS; from Dawson et al. 2013
Recovering topology and power spectrum
Although with the data of BOSS survey, 3-D density distribution is possible to be derived, the separation of each quasar in slightly shifted LOS block us from directly detecting the distribution in between. As a result, interpolation have to be done.
Both Caucci ei al. 2008 and Kitaura et al. 2012 use a Bayesian method to interpolate. A detailed description is present in Pichon et al. 2001, and here only a summarize of this method will be present.
The relation between optical depth and neutral hydrogen is,
\[\tau_l(w) = \frac{c\sigma_0}{H(\bar{z})\sqrt{\pi}} \int \int \int_{-\infty}^{\infty} \frac{n_\mathrm{HI}(x,\mathbf{x}_\perp)}{b(x,\mathbf{x}_\perp)} \exp{\frac{[w-x-v_p(x,\mathbf{x}_\perp)]^2}{b(x,\mathbf{x}_\perp)^2}}dx \delta_D(\mathbf{x}_\perp,\mathbf{x}_{\perp,l})d^2 \mathbf{x}_{\perp,l}\]With some assumption of dark matter, we can translate \(n_\mathrm{HI}\) to density of dark matter \(\rho_\mathrm{DM}\). However, this relation still depends on many other parameters, so we have to determine them first.
Combining all those parameters, we can make an array, \(\mathbf{M}\), and what we want now is the probability of getting \(\mathbf{M}\) from a given data, \(\mathbf{D}\). According to Bayesian theorem, we have,
\[f(\mathbf{M} | \mathbf{D}) = \mathcal{L}(\mathbf{D} | \mathbf{M})f(\mathbf{M})\]which we can (though still a little complicated), compute the likelihood \(\mathcal{L}(\mathbf{D} \| \mathbf{M})\) and derive the prior \( f(\mathbf{M}) \) under some observation. Then, after holding the 3-D density result, visualization can be easily done.
Caucci ei al. 2008 recover the tropology of HI density field at redshift of 2 simulated by model. The result looks very consistent with the simulated data.
Comparison between original HI density field and recovered density field. Top row indicates the unsmoothed field, while bottom row is smoothed. From Caucci ei al. 2008, Figure 9
It is clear that the recovered density field is in a low resolution, because of the discrete distribution of LOS. But after smoothing at a scale larger than the LOS’s separation, we can hardly tell the difference of the original and recovered. Another point worth mentioning is that the recovery in logarithmic space is better than that in linear space.
Kitaura et al. 2012 recovered the power spectrum of density from simulation, and the result is again consist very well.
Comparison of simulated and recovered power spectrum. Red is from simulation, and black is recovered. From Kitaura et al. 2012, Figure 7
Measuring BAO feature from correlation function
A more straightforward constrain on cosmological model is from Busca et al. 2013. The spectra obtained by BOSS is still too sparse in the celestial sphere and the resolution is not high enough to directly recover the density distribution. This may be also the reason which Caucci ei al. 2008 and Kitaura et al. 2012 only provide the tool and use simulated data to recover. Instead correlation function of flux maybe more useful.
To achieve this, Busca et al. 2013 created correlation function as,
\[\hat{\xi}_A = \sum_{ij\in A}w_{ij}\delta_i\delta_j / \sum_{ij\in A} w_{ij}\]where
\[\delta(\lambda) = \frac{f(\lambda)}{C(\lambda)\bar{F}(z)} - 1\]\(w_{ij}\) is the weight of two corresponding pixel in two near quasars, \(f(\lambda)\) is observed flux, and \(C(\lambda)\bar{F}(z)\) is continuum. Volume \(A\) contains all quasars have a distance smaller than \(r\) to one quasar. So if the spectra of two quasars is similar, \(\hat{\xi}_A\) will be bigger than two whose spectra is not.
Now we can expect that in the sound horizon, the correlation function will have a (at least local) maximum, and the position of this peak will provide constrain on cosmological model.
\(\xi(r,\mu)\) averaged over \(0.8 < \mu < 1\). From Busca et al. 2013, Figure 8
Indeed, the correlation function peaks at around 150 Mpc. \(\mu\) here correspond to the transvers direction of or along the LOS, where \(\mu\) near 1 means only selecting sources along LOS. Location of this peak can be used to constrain the real position of BAO peak through two multiplicative factors; and they are related to \(\Omega_m\) and \(\Omega_\Lambda\) separately, so constrain on multiplicative factors can be converted to constrains on cosmological parameters.
Constrains on matter and dark-energy density parameters determined by different method. From Busca et al. 2013, Figure 18
Combined with other constrains from different method, \(\Omega_m\) and \(\Omega_\Lambda\) of model \(\mathrm{\Lambda CDM}\) can be determined much better. Constrain by Ly-\(\alpha\) forest provide a distribution perpendicular to other methods, and it is the only method indicated \(\Omega_\Lambda\) should be greater than 0.5 (or, dark energy is needed).
Furthermore, after adding some constrains called WMAP7 that some parameters effecting multiplicative factors should change in the same direction, Hubble constant in redshift 2.3 \(H(z=2.3)\) can also be determined.
Measurements of \(H(z)/(1+z)\) vs \(z\); result of BAO measurement is the red dot. From Busca et al. 2013, Figure 21
This determination largely expand the redshift range. Without this datapoint, it is not clear that the \(H(z)\) in the past is flat or increasing or decreasing; now this measurement states that our Universe first experienced a decelerating expansion, then turn to accelerating expansion at redshift between 0 and 1.
Future
The future of Ly-\(\alpha\) forest is of course the future of quasar observation. Near future sees the successor of BOSS survey, eBOSS. More and deeper quasar will enhance the completeness of our measurement and help us to trace earlier epoch. Combining data from BOSS and eBOSS, we can have a better constrain on our model of Universe.

This game is played on the following board:
- TURN - On each turn, each player passes his turn or duplicates one of his friendly stacks.
- A stack of size N duplicates by copying itself to an cell in the same row, column or diagonal, at a distance of N cells.
- The intervening cells may be occupied or not.
- An enemy stack at the destiny cell is neutralized (i.e., transformed into a neutral stack) and no copy of the original stack is made.
- GOAL - There are two ways of winning:
- By neutralizing one type of enemy stacks (i.e., neutralize all enemy stacks of size 1, 2 or 3).
- When both players pass, the player with the largest sum of points wins the game (friendly stacks of size N worth N points).
Some sample moves White started by copying c1 to f4. Then Black moves g8-e6. White replies with c1-c4 and Black neutralizes it with e6:c4 (since the black stack at c6 could copy itself to c4).
This game can be player with just pencil and paper. It is presented at 100 Strategic Games for Pen and Paper by Walter Joris.

From 1 January to 31 January 2007, the Ministry of Health reported 789 suspected cases including 96 deaths (case-fatality rate, 12.2%) in the country. Ouargaye district has an attack rate above the epidemic threshold and another three districts, Banfora, Batie and Sapouy are in the alert phase. For more information about the threshold principle, see the article in the Weekly Epidemiological Record.
Cerebrospinal fluid specimens have tested positive for Neisseria meningitidis serogroup A by latex test.
The Ministry of Health is planning to conduct a vaccination campaign in Ouargaye this week.

Hi! I'm Mark Swearingen
Welcome to my profile page
Currently I am very excited to be learning about the back end servers at Central Oregon Community College DevStation. I am on my way to becoming a full stack web developer!
It's an thrilling, exciting and challenging program
So far we have learned HTML, CSS and javaScript as part of the curriculm
My team created a small memory game comparing some javscript code into a memory game. If you know any javaScript, give it a try
