description: We prove an averaging principle which asserts convergence of diffusion processes on domains separated by semi-permeable membranes, when diffusion coefficients tend to infinity while the flux through the membranes remains constant. In the limit, points in each domain are lumped into a single state of a limit Markov chain. The limit chain's intensities are proportional to the membranes' permeability and inversely proportional to the domains' sizes. Analytically, the limit is an example of a singular perturbation in which boundary and transmission conditions play a crucial role. This averaging principle is strongly motivated by recent signaling pathways models of mathematical biology, which are discussed towards the end of the paper.

Heterojunction Solar Cells

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 447-450
description: In this paper we present the 2016-2017 progress made on the CEA silicon heterojunction solar cell (SHJ)
pilot line called ‘LabFab’. The pilot line has entered its second generation phase with the installation of a new sputtering
tool for Transparent Conductive Oxide (TCO) deposition allowing edge masking for junction opening, as well as the
development of busbar-less (BB0) back-end process and an increase of the nominal capacity at 2400 wafers per hour.
Following the wafer market, the pilot line tools were also upgraded to handle both M0 and M2 156x156 mm2 sizes, as
well as lower wafer thicknesses (down to 90μm), thereby increasing the LabFab overall versatility. The line is thus
capable of producing and sorting two main different industrial products: 4 busbar (BB4) and BB0 rear emitter bifacial
cells, with a focus on modules and systems output and reliability. Improving the 20.5% efficiency BB4 baseline end of
2015 with the use of higher quality substrates (high Si bulk lifetime / resistivity ratio) coupled to texturization, PECVD,
PVD and screen printing process optimization, the LabFab production flow has recently reached a lot to lot average
cell efficiency of 21.5% and 22.0% for BB4 and BB0, respectively. The best 244.3cm2 cells with industrial bifacial
processing show 22.3%, 22.1% and 23.3% efficiency for BB4-160μm, BB4-90μm and BB0-160μm respectively.
Modules realized by ribbon conductive gluing on selected BB4 cells show a power cell-to-module ratio of 101+/-1%
in the glass-backsheet (GBS) configuration and 98+/-1% with a glass-glass bifacial design (GG). 324Wp and 313Wp
60-cell GBS modules were acheived with 160μm and 93μm cells respectively. A 72-cell GG record module was
manufactured at 381Wp (flashed with dark backside) and measured at 444Wp under the standardized GE norm
(1000W/m2 front side + 200W/m2 rear side illumination). Our first modules based on BBO cells and the multi-wire
interconnection show similar power as achieved with BB4 cells (386Wp 72-cell, 318Wp 60-cell, GBS, learning stage)
with a high reliability and consistent field data. This allows a short term perspective to equal or slightly increase the
power output for BB0 systems compared to the BB4 reference, taking into account an amount of silver per cell divided
by about a factor 3 to 4.

description: As one of the most fascinating confined water/ice phenomena, two-dimensional square ice has been extensively studied and experimentally confirmed in recent years. Apart from the unidirectional homogeneous square icing patterns considered in previous studies, the multidirectional partitioned square icing patterns are discovered in this study and characterized by molecular dynamics (MD) simulations. Square icing parameters are proposed to quantitatively distinguish the partitioned patterns from the homogeneous patterns and the liquid water. The number of graphene monolayers n is varied in this study, and the results show that it is more energetically favorable to form partitioned square icing patterns when the water molecules are confined between graphite sheets (n >= 2) compared to graphene (n = 1). This phenomenon is insensitive to n as long as n >= 2, because of the short-range nature of the interaction between water molecules and the carbon substrate. Moreover, it is energetically unfavorable to form partitioned square icing patterns for a single layer of water molecules even for n >= 2, verifying that the interaction between layers of water molecules is another dominant factor in the formation of partitioned structures. The conversion from partitioned structure to homogenous square patterns is investigated by changing the pressure and the temperature. Based on the comprehensive MD simulations, this study unveils the formation mechanism of the partitioned square icing patterns.

Heterojunction Solar Cells

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 765-767
description: We demonstrate solar cell fabrication on large area (125mm  125mm) epitaxial wafers of 50μm thickness. During handling and transport no mechanical support was used for the wafers, and the process was identical to the process that was used for 50μm and 160μm Czochralski wafers. Due to the wafer preparation procedure, thin epitaxial wafers were found to be mechanically weaker than Czochralski wafers. This resulted in wafer breakage especially during wet processing. The efficiency of epitaxial cells reached 17%, which was lower than the 19% and 20% efficiencies obtained with 50μm and 160μm Czochralski wafers. The cell results were thus found to be a good metric for substrate quality.
Mechanisms of Metabolic Stress Response Induced by Heart Failure and Cadmium Toxicity

description: Metabolism is broadly defined as chemical reactions in the cell required to sustain life. These reactions are divided into energy generation, anabolism, catabolism, and other uses of metabolites, which encompasses signaling, transcription, disposal of metabolic waste, etc. Heart failure is a chronic condition in which the heart cannot pump enough blood to meet the oxygen and metabolic demands of the body. Initial attempts to overcome these deficiencies include increasing muscle mass, for stronger and faster contractions, and increasing ventricular size, to increase the volume of blood pumped throughout the body. Heart failure with reduced systolic function is characterized by decreased contractility, cardiac hypertrophy, increased ventricular size, and cardiac remodeling and fibrosis. In a transverse aortic constriction (TAC) model of heart failure, we found that overexpressing the NAD+-dependent deacylase sirtuin 5 (SIRT5) in mice protected against the adverse consequences of TAC. SIRT5 overexpressing mice preserved cardiac contractility, maintained ventricular diameter, and exhibited a dampened fibrotic response. Transcriptomic analysis revealed that SIRT5OE suppressed failure associated responses, including immune activation, fatty acid oxidation to metabolic switch, and fibrosis. We conclude that SIRT5 is a limiting factor in the preservation of cardiac function in response to pressure overload. Cadmium is a heavy metal often found in industrial and developing regions. Cigarette smoke is also a common route of exposure. Chronic cadmium exposure leads to cancer and organ system toxicity, particularly in the kidneys. Currently, treatments only target the symptoms of cadmium toxicity and methods of eliminating cadmium post-exposure are not effective. From a high throughput screen, we identified inhibitors of bromodomain and extraterminal (BET) proteins as compounds that protect against cadmium cytotoxicity. Specifically, inhibiting BET family member BRD4 pharmacologically using small molecule JQ1 or genetically through shRNA rescues cadmium-induced cell death, loss of histone acetylation, and disruption of metabolic and signaling pathways. Interestingly, we found that while global histone acetylation decreased upon cadmium treatment, total intracellular acetyl-CoA levels increase. In Chapter 4, I propose further experiments to better understand the mechanisms behind how BET inhibitors rescue cadmium toxicity.

description: In recent years, interstellar dust has become a crucial topic in the study of the high and very high redshift Universe. Evidence points to the existence of high dust masses in massive star forming galaxies already during the Epoch of Reionization, potentially affecting the escape of ionising photons into the intergalactic medium. Moreover, correctly estimating dust extinction at UV wavelengths is essential for precise ultra-violet luminosity function (UVLF) prediction and interpretation. In this paper, we investigate the impact of dust on the observed properties of high redshift galaxies, and cosmic reionization. To this end, we couple a physical model for dust production to the fully coupled radiation-hydrodynamics cosmological simulation code RAMSES-CUDATON, and perform a $16^3$, $2048^3$, simulation, that we call DUSTiER for DUST in the Epoch of Reionization. It yields galaxies with dust masses and UV slopes compatible with constraints at z $\geq 5$. We find that extinction has a dramatic impact on the bright end of the UVLF, even as early as $\rm z=8$, and our dusty UVLFs are in better agreement with observations than dust-less UVLFs. The fraction of obscured star formation rises up to 45% at $\rm z=5$, in agreement with some of the latest results from ALMA. Finally, we find that dust reduces the escape of ionising photons from galaxies more massive than $10^{10} M_\odot$ (brighter than $\approx -18$ MAB1600) by >10%, and possibly up to 80-90% for our most massive galaxies. Nevertheless, we find that the ionising escape fraction is first and foremost set by neutral Hydrogen in galaxies, as the latter produces transmissions up to 100 times smaller than through dust alone.

description: We propose a new reinforcement learning algorithm for partially observable Markov decision processes (POMDP) based on spectral decomposition methods. While spectral methods have been previously employed for consistent learning of (passive) latent variable models such as hidden Markov models, POMDPs are more challenging since the learner interacts with the environment and possibly changes the future observations in the process. We devise a learning algorithm running through episodes, in each episode we employ spectral techniques to learn the POMDP parameters from a trajectory generated by a fixed policy. At the end of the episode, an optimization oracle returns the optimal memoryless planning policy which maximizes the expected reward based on the estimated POMDP model. We prove an order-optimal regret bound with respect to the optimal memoryless policy and efficient scaling with respect to the dimensionality of observation and action spaces.

Heterojunction Solar Cells

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 791-796
description: Most solar-cell models assume, either explicitly or tacitly, that carrier collection proceeds normal to the
junction before charge separation and parallel thereto once the junction has been surpassed. In the case of siliconheterojunction
cells, this latter transverse collection process is supposed to take place basically across the transparent
conductive oxide deposited on the front side of the device. In order to confirm this, cells with and without a
transparent conductive oxide (which we call respectively standard and bare cells) have been prepared and tested.
Although the predictions of the so-called normal-plus-parallel collection hypothesis for a bare cell are a very high
series resistance and a current density being essentially flat across the cell active-area surface, experimental results
are clearly different. Bare cells show series resistances of the order of 1 Ohm and a current collection limited to the
cell areas being sufficiently near the front contacts. In consequence, transverse-current collection mechanisms of SHJ
solar cells have to be revised. The role of an inversion layer at the interface is discussed. Then, a qualitative model is
proposed. This model is based on the fact that, once created in the absorbent, a free minority carrier diffuses not only
straight towards the junction, but also in all other directions from the point where the photon has been absorbed. This
consideration not only makes the above-mentioned series-resistance estimate invalid, but also limits effective
collection to a distance from the metal finger of the order of the minority-carrier diffusion length. Internal-quantumefficiency
and LBIC measurements have yielded results in accordance with the simple model proposed.

description: In the task of discriminating between nonorthogonal quantum states from multiple copies, the key parameters are the error probability and the resources (number of copies) used. Previous studies have considered the task of minimizing the average error probability for fixed resources. Here we introduce a new state discrimination task: minimizing the average resources for a fixed admissible error probability. We show that this new task is not performed optimally by previously known strategies, and derive and experimentally test a detection scheme that performs better.

description: Large and less-biased samples of star-forming galaxies are essential to investigate galaxy evolution. H$\rmα$ emission line is one of the most reliable tracers of star-forming galaxies because its strength is directly related to recent star formation. However, it is observationally expensive to construct large samples of H$\rmα$ emitters by spectroscopic or narrow-band imaging survey at high-redshifts. In this work, we demonstrate a method to extract H$\rmα$ fluxes of galaxies at $z=2.1$-$2.5$ from $K_s$ broad-band photometry of ZFOURGE catalog. Combined with 25-39 other filters, we estimate the emission line fluxes by SED fitting with stellar population models that incorporate emission-line strengths. 2005 galaxies are selected as H$\rmα$ emitters by our method and their fluxes show good agreement with previous measurements in the literature. On the other hand, there are more H$\rmα$ luminous galaxies than previously reported. The discrepancy can be explained by extended H$\rmα$ profiles of massive galaxies and a luminosity dependence of dust attenuation, which are not taken into account in the previous work. We also find that there are a large number of low-mass galaxies with much higher specific star formation rate (sSFR) than expected from the extrapolated star formation main sequence. Such low-mass galaxies exhibit larger ratios between H$\rmα$ and UV fluxes compared to more massive high sSFR galaxies. This result implies that a ``starburst'' mode may differ among galaxies: low-mass galaxies appear to assemble their stellar mass via short-duration bursts while more massive galaxies tend to experience longer-duration ($>10\ \mathrm{Myr}$) bursts.

description: Bond configuration and microstructure of hydrogenated amorphous silicon nitride films (SiNx:H) deposited by PECVD
have been investigated after deposition of SiN as well as after the firing process. Deposition parameters were varied in a
statistical full factorial design (DoE) and their effect on the film properties was studied in both steps, after the deposition
and after the firing. Result revealed that the change in gas flow ratio of NH3/(SiH4+NH3) and the temperature of the
deposition are the two significant factors for the composition and the bond structure of SiN. The low [N]/[Si] ratio
deduced by XPS in Si-rich SiN layers results better surface passivation with high minority carrier lifetime after
deposition. The density of Si-N bonds was low in these layers and the densification occurs mostly due to the Si-H breaks
after firing. The improvement of minority carrier lifetime has been observed in N-rich SiN layers deposited by identical
gas flow of ammonia and silane which shows a high density of Si-N after deposition. It has been seen that the atomic
density of SiN plays a key role on the thermal stability of SiN at high temperatures.

description: To close the overturning circulation, dense bottom water must upwell via turbulent mixing. Recent studies have identified thin bottom boundary layers (BLs) as locations of intense upwelling, yet it remains unclear how they interact with and shape the large-scale circulation of the abyssal ocean. The current understanding of this BL--interior coupling is shaped by 1D theory, suggesting that variations in locally produced BL transport generate exchange with the interior and thus a global circulation. Until now, however, this picture has been based on a 1D theory that fails to capture the local evolution in even highly idealized 2D geometries. The present work applies BL theory to revised 1D dynamics, which more naturally generalizes to two and three dimensions. The BL is assumed to be in quasi-equilibrium between the upwelling of dense water and the convergence of downward buoyancy fluxes. The BL transport, for which explicit formulae are presented, exerts an influence on the interior by modifying the bottom boundary condition. In 1D, this BL transport is independent of the interior evolution, but in 2D the BL and interior are fully coupled. Once interior variables and the bottom slope are allowed to vary in the horizontal, the resulting convergences and divergences in the BL transport exchange mass with the interior. This framework allows for the analysis of previously inaccessible problems such as the BL--interior coupling in the presence of an exponential interior stratification, laying the foundation for developing a full theory for the abyssal circulation.

description: We compare the set of local galaxies having dynamically measured black holes with a large, unbiased sample of galaxies extracted from the Sloan Digital Sky Survey. We confirm earlier work showing that the majority of black hole hosts have significantly higher velocity dispersions sigma than local galaxies of similar stellar mass. We use Monte-Carlo simulations to illustrate the effect on black hole scaling relations if this bias arises from the requirement that the black hole sphere of influence must be resolved to measure black hole masses with spatially resolved kinematics. We find that this selection effect artificially increases the normalization of the Mbh-sigma relation by a factor of at least ~3; the bias for the Mbh-Mstar relation is even larger. Our Monte Carlo simulations and analysis of the residuals from scaling relations both indicate that sigma is more fundamental than Mstar or effective radius. In particular, the Mbh-Mstar relation is mostly a consequence of the Mbh-sigma and sigma-Mstar relations, and is heavily biased by up to a factor of 50 at small masses. This helps resolve the discrepancy between dynamically-based black hole-galaxy scaling relations versus those of active galaxies. Our simulations also disfavour broad distributions of black hole masses at fixed sigma. Correcting for this bias suggests that the calibration factor used to estimate black hole masses in active galaxies should be reduced to values of fvir~1. Black hole mass densities should also be proportionally smaller, perhaps implying significantly higher radiative efficiencies/black hole spins. Reducing black hole masses also reduces the gravitational wave signal expected from black hole mergers.

description: We present compact analytic expressions for 3-flavor neutrino oscillation probabilities with invisible neutrino decay, where matter effects have been explicitly included. We take into account the possibility that the oscillation and decay components of the effective Hamiltonian do not commute. This is achieved by employing the techniques of inverse Baker-Campbell-Hausdorff (BCH) expansion and the Cayley-Hamilton theorem applied in the 3-flavor framework. If only the vacuum mass eigenstate $ν_3$ decays, we show that the treatment of neutrino propagation may be reduced to an effective 2-flavor analysis in the One Mass Scale Dominance (OMSD) approximation. The oscillation probabilities for $P_{μμ}$, $P_{ee}$, $P_{eμ}$ and $P_{μe}$ -- relevant for reactor, long baseline and atmospheric neutrino experiments -- are obtained as perturbative expansions for the case of only $ν_3$ decay, as well as for the more general scenario where all components of the decay matrix are non-zero. The analytic results thus obtained match the exact numerical results for constant density matter to a high precision and provide physical insights into possible effects of the decay of neutrinos as they propagate through Earth matter. We find that the effects of neutrino decay are most likely to be observable in $P_{μμ}$. We also point out that at any long baseline, the oscillation dips in $P_{μμ}$ can show higher survival probabilities in the case with decay than without decay, and explain this feature using our analytic approximations.

Thin Film and Foil-Based Solar Cells

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 431-436
description: As PV production ramps up and numerous installed solar panels reach their end of life, potentially
huge waste sources of silicon become available. Such silicon can be recovered and recycled back into the PV
industry, for making solar cells directly on the recycled Si. In cases where the recycled Si is of very low purity and
cannot be used directly as active material, they can instead be used to make low-cost Si supporting carriers that are
highly-conductive. These supporting substrates have been made using low-cost techniques such as by sintering of
low-cost Si powders. These conductive substrates can act as mechanical carriers of thin silicon (< 50 μm) and as rearcontacts
in what is called a wafer-equivalent concept. In this work, thin epitaxial silicon foils from the porous siliconbased
lift-off process are used. For conductive bonding, low-temperature Ag paste from INKRON (IPC-114) has
been preferably used due to its robust bonding properties (low temperature curing, high conductivity and minimal
volume change). As a first demonstrative step, thin (<50 μm) epifoil-based and thinned (<50 μm) Cz-based cells
conductively bonded onto highly-doped p+ Cz silicon substrates have been fabricated. We chose the heterojunction
technology for cell fabrication, leading to 15.7% efficiency for the best epifoil cell, partially processed after
conductive bonding. It was observed that the cell performance of bonded cells are comparable to that of non-bonded
epifoil cells that were processed freestanding. Furthermore, in order to reduce costs of the conductive bonding step,
extensive simulations have been performed to understand the best configuration and pattern geometry for the bonding
layer. This work is done in framework of H2020 EU project CABRISS.

description: Given a simple Lie group $H$ of real rank at least $2$ we show that the maximum cardinality of a set of isospectral non-isometric $H$-locally symmetric spaces of volume at most $x$ grows at least as fast as $x^{c\log x/ (\log\log x)^2}$ where $c = c(H)$ is a positive constant. In contrast with the real rank $1$ case, this bound comes surprisingly close to the total number of such spaces as estimated in a previous work of Belolipetsky and Lubotzky [BL]. Our proof uses Sunada's method, results of [BL], and some deep results from number theory. We also discuss an open number-theoretical problem which would imply an even faster growth estimate.

Result shows that thickness of 10 nm is preferable, thickness more or less than 10 nm results in lower fill factor (FF) and short circuit current density (Jsc). 10 nm ZnS was then deposited on the textured p-Si and Al was used as back electrode. The device exhibits power conversion efficiency (PCE) of 8.83% with open circuit voltage (Voc) of 0.517 V, Jsc of 31.047 mA/cm2 and FF of 55.0%. The efficiency is the highest value reported so far to our knowledge for n-ZnS/p-Si heterojunction solar cells. Simulation of the device was carried out by wx-AMPS. It shows that the contact barrier of front surface mainly influences the FF, while the contact barrier of back surface influences the Voc. The simulation points the way for efficiency improvement of the device. Experiments according to the simulation confirmed the result.

description: It was between the Late Neolithic and the Early Bronze Age when wool was introduced as raw material for textile production. It is expected that this innovation had a comprehensive effect on the socio-economic life of people and their environment. However, little is known about spatio-temporal trajectories of the process and the environmental influences it actually had. The approach presented demonstrates how such a comprehensive and complex research question may be operationalized. Decomposition of the overall process and gathering of information from different fields allows to reconstruct particular aspects of the phenomenon and their diachronic change. Subsequent synthesis enables addressing the overall question. This paper focuses on the role of landscape within the process of wool sheep introduction. Besides covering the particular approach to reconstruct herdingrelated landscape changes it is shown how deeply different disciplinary approaches are interconnected. Finally, difficulties and constraints of data integration are addressed.

description: Light and elevated temperature induced degradation (LeTID) affects significantly the performance of
multicrystalline Silicon (mc-Si) solar cells. The underlying mechanisms of LeTID and following regeneration are still
unknown and might depend on contaminations. To investigate the influence of different transition metals on the
degradation and regeneration behavior, mc-Si ingots were intentionally contaminated in the Si melt with either
20 ppma Fe, Cu, Cr or a combination of Fe and Cu. Minority charge carrier lifetime (eff) samples were processed and
the degradation and regeneration behavior under illumination (0.9 ± 0.1 sun) and elevated temperature (75°C) is
measured repetitively by time-resolved photoluminescence imaging (TR-PLI) at room temperature. The resulting
minority charge carrier lifetime maps are analyzed and the effective defect concentration within one sample and also
for differently contaminated samples were calculated. This approach leads to different defect generation rates for the
differently contaminated samples, which might hint to an influence of different transition metals on the LeTID
causing defect.

description: El objetivo de este trabajo es determinar cuál es el comienzo del término prescriptivo de la obligación, en los múltiples cobros judiciales y extrajudiciales, que se pueden presentar en ejercicio de la cláusula aceleratoria con el mismo título valor, con sus implicaciones sustanciales y procesales, se haya o no notificado al deudor. Así mismo identificar figuras que pueden tener injerencia en el múltiple cobro con cláusula aceleratoria. Las principales conclusiones a que se llega, se pueden sintetizar, en que, tratándose de los múltiples ejercicios de la cláusula aceleratoria, existen ciertos eventos en los cuales el cobro o la demanda anterior, afectan el término prescriptivo de la posterior. En especial, el comienzo del término para contabilizar la prescripción de la obligación de la siguiente. En consecuencia, puede afectar el cobro de los títulos valores, en especial el Pagaré, que es el título valor por excelencia donde más se utilizan estas cláusulas. Este trabajo pretende ubicar y tratar de manera jurídica los principales eventos en que esa afectación puede o no ocurrir. Eventos tales como el cobro extrajudicial, el requerimiento directo, entre otros.
description: The objective of this work is to determine the beginning of the statute of limitations of the obligation, in the multiple judicial and extrajudicial collections, which may be presented in the exercise of the acceleration clause with the same security, with its substantial and procedural implications, whether or not the debtor has been notified. It also identifies figures that may be involved in the multiple collection with an acceleration clause. The main conclusions reached can be summarized as follows: in the case of multiple exercises of the acceleration clause, there are certain events in which the previous collection or claim affects the statute of limitations of the subsequent one. In particular, the beginning of the term to count the statute of limitations of the obligation of the subsequent one. Consequently, it may affect the collection of securities, especially the Promissory Note, which is the security par excellence where these clauses are most used. This work intends to locate and treat in a legal manner the main events in which this affectation may or may not occur. Events such as extrajudicial collection, direct demand, among others.
Sign of the Feynman Propagator and Irreversibility

description: For the interacting Feynman propagator $ Δ_{F,int}(x,y) $ of scalar electrodynamics, we show that the sign property, $ \operatorname{Re} iΔ_{F,int} \geq 0 $, hinges on the reversibility of time evolution. In contrast, $ \operatorname{Im} iΔ_{F,int} $ is indeterminate. When we switch to reduced dynamics under the weak coupling approximation, the positive semidefinite sign of $ \operatorname{Re} iΔ_{F,int} $ is generally lost, unless we impose severe restrictions on the Kraus operators that govern time evolution. With another approximation, the rotating wave approximation, we may recover the sign by restricting the test functions to exponentials under certain conditions.
description: To make the paper more self-contained, a few more background comments were added in this version, further to the suggestion of the referee

Year: 2009

description: Background: The International Consensus Group for Hematology Review recommends manual blood smears for new findings from automated complete blood cell (CBC) tests. However, in outpatients, the rate of peripheral manual blood smear reviews is uncertain, as is the effect of historical results on this rate. Methods: In a prospective cohort study of 687,955 members of a health maintenance organization, we extracted 39,759 consecutive automated CBC test results and determined the rate of manual peripheral smear reviews that were indicated using different triggering criteria, and historical results. Results: Individual triggering values increased from 10.7% to 19.5% when comparing our criteria to those of the consensus criteria. The proportion of CBC test results with at least one triggering value was 7.2% using our criteria, compared to 13.9% with the inclusion of a mean corpuscular volume <75 and a plus one immature granulocyte flag according to the consensus committee. Availability of historical data decreased our peripheral smear review rate to 2.6%. Conclusions: The peripheral smear review rate in outpatients using the consensus criteria was higher than with our less stringent criteria. If historical data are available and no clinical utility is demonstrated for the additional consensus criteria, an acceptable out-patient review rate might be as low as 2.6%.

Classical stochastic dynamics and continuous matrix product states: gauge transformations, conditioned and driven processes, and equivalence of trajectory ensembles

Year: 2016
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Borrowing ideas from open quantum systems, we describe a formalism to encode ensembles of trajectories of classical stochastic dynamics in terms of continuous matrix product states (cMPSs). We show how to define in this approach "biased" or "conditioned" ensembles where the probability of trajectories is biased from that of the natural dynamics by some condition on trajectory observables. In particular, we show that the generalised Doob transform which maps a conditioned process to an equivalent "auxiliary" or "driven" process (one where the same conditioned set of trajectories is generated by a proper stochastic dynamics) is just a gauge transformation of the corresponding cMPS. We also discuss how within this framework one can easily prove properties of the dynamics such as trajectory ensemble equivalence and fluctuation theorems.

description: This work presents results concerning sintering of silicon powder based wafers and ingots produced the by
Spark Plasma Sintering (SPS) method. It is shown that wafering of such ingots can be done by conventional wire sawing.
Light microscopy, scanning electron microscopy, energy dispersive spectroscopy, Raman spectroscopy, as well as
minority carrier life time measurements were used for the analysis of silicon wafers fabricated by SPS followed by wire
sawing. It is found that during the SPS process, material inhomogeneity of sintered ingots and wafers occurs.
Nevertheless, the inhomogeneity can be smoothed by proper optimized sintered conditions for the large scale (up to 8
inch) ingots and wafers. It is found that the SPS process, being applied to Si powder, provides formation of Si material
(wafers or ingots), which has structural properties similar to those for multicrystalline silicon (mc-Si). In case if silicon
powder has solar grade quality, minority carrier lifetime values are comparable with those for mc-Si substrates. It is
concluded that SPS silicon structures can be potentially considered as a base for low-cost Si based photovoltaics.
