LRO Diviner Nonlinear Response and Opposition Effect Corrections
Aboard the Lunar Reconnaissance Orbiter, the Diviner Lunar Radiometer Experiment measures thermal radiation to determine the brightness temperature of the lunar surface. As with the Mars Climate Sounder (upon which Diviner is based), we use pre-flight calibration data to correct for the nonlinear response in Diviner’s detectors, which in-turn accounts for much of the detector non-uniformity within channels. Furthermore, channels 8 and 9 exhibit unexpectedly high brightness temperatures close to the equator around midday, with even higher brightness temperatures when observing lunar highlands as opposed to maria. Unexpectedly high brightness temperatures around midday at the equator is reminiscent of the opposition effect known to exist on the Moon at low phase angles in Visual to Near Infra-Red (VNIR) wavelengths. Diviner channel 2 data (which detects solar radiation reflected by the Moon) shows this opposition effect, which is more pronounced in the highlands than the maria. We interpret a correlation we observe between channel 2 detected radiance and channel 8 and 9 brightness temperature as due to incomplete blocking of reflected solar radiation. This leads us to an opposition effect correction for Diviner channels 8 and 9 dependent on Diviner’s solar channel data. Whether this is a direct leak of VNIR light upon the detectors, or solar heating of blocking filters, which then radiate infrared radiation upon the detectors, is yet to be determined. We can use the nonlinearity and opposition effect corrections to recharacterize the spectral emissivity of the lunar regolith, which we can then compare to laboratory spectra.

Given that θ is the true proportion of people over age 40 in my community to have hypertension, I would assume θ ∼ Beta(α, β) Encoding my prior belief about θ (and it’s point estimate such as mean), let’s assume $\hat{\theta} = 0.6$. From Beta distribution
\begin{align} \int \theta p(\theta) d\theta = \frac{\alpha}{\alpha + \beta} = 0.6 \end{align}
Let’s choose α = 6, β = 4
\begin{equation} \begin{split} p(\theta | x) & \propto p(x | \theta) p(\theta) \end{split} \end{equation}
Title
- During the last few year, growing body of evidence has appeared that support the existence of neutrophils subpopulation in mammals, both in homeostasis and diseases. There are two main facts that explain their existence: 1.-Different lineage or embryonic origin of the specific group of neutrophils. 2.-Different environmental signals triggered by a stimulus that promotes the appearance of distinct neutrophils subset from a single original group. Of importance, each subpopulation can be recognized by their unique molecular profile.
In zebrafish, there are no antecedents regarding the molecular profile of neutrophils, neither before nor after a harmful insult. Nevertheless, there is evidence that strongly suggests the existence of at least two neutrophils subpopulation during an inflammatory process. One neutrophils subset respond first and migrate to the affected area across the interstitial tissue and a second subset responds later and travels through the bloodstream to reach the insulted zone.
\(\sqrt{ }\)During embryonic and larval stages, in zebrafish coexist two types of neutrophils that have the ability to respond to a harmful stimulus at the same time, the primitive and definitive neutrophils. These two groups have different embryonic origin; primitive ones arise from the rostral blood island and definitive neutrophils from the caudal hematopoietic tissue. As a consequence, primitive neutrophils are tissue cells mainly located in the head region. On the contrary, definitive neutrophils preferably remain in the hematopoietic tissue at the ventral posterior region of the tail until activation.
Tectonic Evolution of Death Valley
Abstract
Extension in Death Valley is interpreted as a Basin and Range extension associated with the developing Pacific-North America plate boundary in western North America \cite{Norton_2011}, or it may interpreted as the product of a pull-apart basin produced by normal faults trending NW-SE. Here we present supporting evidence that the basins produced in Death Valley are a combination of compressional tectonics related to subduction in the Cretaceous and a series of pull-apart basins produced by NW-SE trending normal faults and strike-slip faults parallel to the SE trending Furnace Creek fault and San Andreas Fault. We present evidence by focusing on the timing and tectonics of the Pahrump Group, Noonday Dolomites, Wood Canyon Fomration, Zabriskie Quartzite, Carrara Formation, and Bonanza King Formation in Death Valley and observing the structural deformation. By using methods such as measuring the trend of faults and structural geology techniques, we can make observations in the field supporting our hypothesis. We focus on the compressional tectonics during the Cretaceous and extensional tectonics during the late Cenozoic of this region.

An example of an inline equation: a + b = αγ. To display an equation, you use the equation
environment. \begin{equation}\label{e.Newton}
\left(\frac{\partial^2 x}{\partial t^2}\right) = -\frac{GM}{r^2}
\end{equation} We can also do display math without an equation number: $$
G_{\mu\nu} = 8\pi T_{\mu\nu}.
$$ The equation
environment allows us to cross-reference equations: equation ([e.Newton]) is Newton’s equation. Citations are handled with the cite
command and its variants: “observations of the quiescent luminosity of MAXI J0556-332 suggest the presence of a strong heat source in its accreted envelope \cite{2015ApJ...809L..31D}.” Notice that this style uses an author-date system. With author-date, there are fancier versions of the cite
command: “with the release of the second MESA paper, \citet{Paxton_2013}”. Here I would like to cite this result \cite{Deibel_2016}.

Silicon Photomultiplier Structure and Properties
The Silicon Photomultiplier (SiPM) is essentially an array of silicon avalanche p-n photodiodes operating in Geiger-mode. It is necessary to review some basics of the p-n junction to understand how the SiPM operates.
A p-n junction is the fusion of a p-type and n-type semiconductor together. A P-type region contains a majority of hole (positive) carriers and few electrons. A N-type region contains a majority of mobile electrons and few holes. Properties exist that can be exploited for the use of the SiPM when the two regions are brought into contact, diffusion of carrier concentration being one of those properties. Holes from the p-type region diffuse to the n-type region and electrons from n-type region diffuse to the p-type region leaving behind negatively charged ionized acceptor atoms and positively charges ionized donor atoms respectively. As a result of this diffusion, a narrow region on both sides of the p-n junction become nearly depleted of mobile charge carriers, called the depletion layer [1]. The depletion layer contains only fixed charges of negative ions in the p-region and positively charged ions in the n-region. These fixed charges created an internal electric field that points from n-side to p-side as seen in figure 1. There then exists a built in voltage at the interface preventing electrons moving into p-side and holes into n-side. The built in voltage goes as $V_{bi}=\frac{kT}{q}ln(\frac{N_DN_A}{n_i^2})$, where ND are donor concentrations, NA are acceptor concentrations, and ni is the intrinsic carrier concentration [3]. No net current will flow across the junction while unbiased.
\DeclareFloatingEnvironment [fileext=box,placement=!t,name=Box]floatbox Sane as it Ever Was: The Historical Meaning of the Crisis in Psychology
In an article entitled “Has Psychology Failed?” Joseph Jastrow reflects on whether prominent scholars such as William James and Stanley Hall had been right to be pessimistic about the advancement of psychology since the days of its conception as an empirical science. He notes the following:
“The present text-book chaos is the work of drifting pilots. They leave the student with the impression of a patch-work quilt whereas actually the mind is a tapestry.” (Jastrow, 1935, p. 268)
In this preface to the chapters of a book that concern the specific case of evaluating competing ætiologies of developmental dyslexia, I conjecture that the general failure to advance the empirical social sciences as a natural science lies in the not so recent past. The current crisis of confidence in the empirical record of the social and life sciences is not due to the (ab)use of inferential statistics as a means to haul in huge quantities of scientific knowledge, but is more likely due to the inability of the scientific community to stop expanding the patch-work quilt by suggesting a new theory (or paradigm) for each freshly caught fact. That is, this crisis concerns the curious case of an empirical science in which the very thing that separates this branch from the other disciplines –knowledge inference by means empirical tests of theoretical claims– seems to have little or no authority at the level of evaluating the truth-likeness (verisimilitude) of theories.
The conjecture: If empirical disciplines of social science experienced crises of confidence before statistical hypothesis testing was adopted as the main tool for scientific inference, it is unlikely that inferential statistics are the true cause of the current crisis. Reforms exclusively aimed at improving this type of scientific inference, although necessary, are unlikely to be successful in preventing another crisis from happening again in the next decade. Based on an examination of historical commentaries on the state of theory evaluation in psychological science, I will suggest that the only way forward for the empirical social sciences in general, is to join the tapestry weaving guild and establish a consensus science, a science in which “theory and data speak more for themselves” (Fanelli, 2010). In the ‘softer’ fields of empirical science theoretical disputes mainly concern circular ‘special sauce’ arguments: “You did not evidence the phenomenon I study, because you do not know what it takes to evidence the phenomenon I study and neither do I when you ask me to be explicit about it a-priori”.
This transition will not happen overnight, but as I will argue in what follows, the claim of being young and still maturing as a science as an excuse for its delayed occurrence is untenable. The importance of transforming into a consensus empirical science was recognised in the earliest Principia of Psychology. Moreover, I believe it is essential to start this discussion right now, because the Open Science movement has all the potential to play a crucial role in laying down the foundations for a discipline that studies human nature as a natural science within the next decade.
