description: Rickettsiae may cause febrile infections in humans in tropical and subtropical regions. From Madagascar, no molecular data on the role of rickettsioses in febrile patients are available. Blood samples from patients presenting with fever in the area of the capital Antananarivo were screened for the presence of rickettsial DNA. EDTA (ethylenediaminetetraacetic acid) blood from 1020 patients presenting with pyrexia > 38.5 °C was analyzed by gltA-specific qPCR. Positive samples were confirmed by ompB-specific qPCR. From confirmed samples, the gltA amplicons were sequenced and subjected to phylogenetic analysis. From five gltA-reactive samples, two were confirmed by ompB-specific qPCR. The gltA sequence in the sample taken from a 38-year-old female showed 100% homology with R. typhi. The other sample taken from a 1.5-year-old infant was 100% homologous to R. felis. Tick-borne rickettsiae were not identified. The overall rate of febrile patients with molecular evidence for a rickettsial infection from the Madagascan study site was 0.2% (2/1020 patients). Flea-borne rickettsiosis is a rare but neglected cause of infection in Madagascar. Accurate diagnosis may prompt adequate antimicrobial treatment.
Confined massive circumstellar shell in type IIL SN 2008fq

description: I explore a phenomenon of the circumstellar H alpha and H beta absorption lines in the spectrum of luminous type IIL SN 2008fq taken on day 6.8 after the discovery. The absorpion is identified with the radiatively accelerated preshock wind up to ~800 km/s. The required initial luminosity is attributed to the earlier circumstellar interaction with the confined dense shell of ~0.08 Msun. The modelling of similar luminous type IIL SN 1998S based on the same approach results in the comparable shell mass of ~0.1 Msun. More than 1 dex larger mass of the confined dense shell of both SNe IIL compared to that of type IIP supernovae is attributed to the larger progenitor mass of type IIL supernovae.

description: This study assesses the educational distribution in rural and urban areas––both at national and provincial levels––by employing the education Gini coefficient and decomposition analyses. The findings of the study reveal that rural and urban educational inequalities are generally improving over time as shown by the education Gini estimates for rural and urban areas. Decomposition analyses show that, at the national level, the rural-urban education inequality gap or Rural-Urban Gap is the main contributor to education inequality; in contrast, at the provincial level, the main contributor is the inequality within rural areas. This implies that educational provision should be enhanced in rural areas. The paper pays particular attention to the province of Tawi-Tawi which is the only province that experienced an increase in both rural and urban educational inequalities. Accounting for sex subgroups, modified decomposition analysis is able to ascertain that such observation is due to the dismal educational distribution of its rural population. On the other hand, the negative inequality growth contributions of its urban population could be viewed as a possible evidence of labor migration.

description: The long-time behavior of the velocity autocorrelation function in a classical two-dimensional electric conduction system is studied by the molecular dynamics simulation. In equilibrium, the effect of coexistence of many-body interactions and a random potential is investigated. A crossover from a positive tail proportional to $t^{-1}$, to a negative tail proportional to $-t^{-2}$ is observed as the strength of the random potential increases. In nonequilibrium, the positive tail is enhanced whereas the negative tail appears at earlier times as an electric field increases.

description: Here we present a computational tool for optical tweezers which calculates the particle tracking signal measured with a quadrant detector and the shot-noise limit to position resolution. The tool is a piece of Matlab code which functions within the freely available Optical Tweezers Toolbox. It allows the measurements performed in most optical tweezers experiments to be theoretically characterized in a fast and easy manner. The code supports particles with arbitrary size, any optical fields and any combination of objective and condenser, and performs a full vector calculation of the relevant fields. Example calculations are presented which show the tracking signals for different particles, and the shot noise limit to position sensitivity as a function of the effective condenser NA.
Effect of Implant-Abutment Connection on Bone Level and Survival: A Systematic Review and Meta-Analysis
Creators: name: Schmidt, Angela
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Background and Objectives:
Macroscopic implant design and features have a critical role in the success of the integration and long-term survival of the implants. Key characteristics surrounding the connection of the implant to the abutment have been seen to impact the marginal bone levels surrounding the implant and therefore impact the survival. This review is to evaluate four configurations of implant to abutment connection and quantify the change in marginal bone levels and survival rates.
Method of Review:
Electronic search was completed of four major databases and then were reviewed by two blinded, independent reviewers following the inclusion criteria. Data from the included articles was categorized into four implant categories: external hex, internal connection >45°, internal connection <45°, and tissue level and then broken into follow up intervals. Data was extracted for marginal bone levels and implant survival.
Findings:
Review of the databases resulted in 3,082 screened articles. Ultimately 465 were included in full text review, 270 of which included for synthesis and analysis. Mean marginal bone levels were reported and analyzed for all four implant configurations over the time intervals of short, mid and long term. Implant survival was analyzed and reported for all four implant configurations over the time intervals as well. Statistical data and forest plots to follow in full text.
Conclusion:
The configuration of the implant to abutment junction in dental implants has a statistical significant effect on changes seen to the marginal bone levels surrounding the implants. Theseeffects can be seen throughout both short, mid, and long term follow up. It was seen that the external hex and internal connection >45° implants performed similarly and that the tissue level and internal connection <45° implants performed similarly.

description: Automated driving is an active area of research in both industry and academia. Automated Parking, which is automated driving in a restricted scenario of parking with low speed manoeuvring, is a key enabling product for fully autonomous driving systems. It is also an important milestone from the perspective of a higher end system built from the previous generation driver assistance systems comprising of collision warning, pedestrian detection, etc. In this paper, we discuss the design and implementation of an automated parking system from the perspective of computer vision algorithms. Designing a low-cost system with functional safety is challenging and leads to a large gap between the prototype and the end product, in order to handle all the corner cases. We demonstrate how camera systems are crucial for addressing a range of automated parking use cases and also, to add robustness to systems based on active distance measuring sensors, such as ultrasonics and radar. The key vision modules which realize the parking use cases are 3D reconstruction, parking slot marking recognition, freespace and vehicle/pedestrian detection. We detail the important parking use cases and demonstrate how to combine the vision modules to form a robust parking system. To the best of the authors' knowledge, this is the first detailed discussion of a systemic view of a commercial automated parking system.

description: We present a comprehensive experimental study of magnetization and magnetocaloric effect (MCE) in double perovskite (DP) materials $R_2$NiMnO$_6$ with $R =$ Pr, Nd, Sm, Gd, Tb, and Dy. While a paramagnetic to ferromagnetic transition, with T$_{\rm C}$ in the range $\sim 100 - 200~$K, is a common feature that can be attributed to the ordering of Mn$^{4+}$ and Ni$^{2+}$ magnetic moments, qualitatively distinct behavior depending on the choice of $R$ is observed at low temperatures. These low-temperature anomalies in magnetization are also manifest in the change in magnetic entropy, $-ΔS_{M}$, whose sign depends on the choice of $R$. In order to understand these results, we present theoretical analysis based on mean-field approximation and Monte Carlo simulations on a minimal spin model. The model correctly captures the key features of the experimental observations.

description: Thermal reverberation in accretion discs of active galactic nuclei is thought to be the reason of the continuum UV/optical time lags seen in these sources. Recently, we studied thermal reverberation of a standard Novikov-Thorne accretion disc illuminated by an X-ray point-like source, and we derived an analytic prescription for the time lags as function of wavelength. In this work, we use this analytic function to fit the time-lags spectra of seven Seyferts, that have been intensively monitored, in many wave-bands, in the last few years. We find that thermal reverberation can explain the observed UV/optical time lags in all these sources. Contrary to previous claims, the magnitude of the observed UV/optical time-lags is exactly as expected in the case of a standard accretion disc in the lamp-post geometry, given the black hole mass and the accretion rate estimates for the objects we study. We derive estimates of the disc accretion rates and corona height for a non-spinning and a maximally spinning black hole scenarios. We also find that the modelling of the continuum optical/UV time-lags can be used to estimate the black hole spin, when combined with additional information. We also find that the model under-predicts the observed X-ray to UV time-lags, but this difference is probably due to the broad X-ray auto-correlation function of these sources.

description: One of the basic conditions for sustainable enterprise development is economic efficiency. This study assesses the performance of two agricultural cooperatives in the Philippines – the Sorosoro Ibaba Development Cooperative (SIDC) and the Subasta Integrated Farmers Multipurpose Cooperative (SIFMPC) to shed light on the viability and efficiency of cooperatives as economic enterprises. Descriptive analysis based on the economic efficiency concept under the sustainable enterprise development framework of the International Labour Organization and quantitative analysis using financial indicators are used to assess the performance of the cooperatives under study. Key findings show that cooperatives can perform efficiently if they adopt market-complementing activities such as vertical integration, quality upgrading and productivity and low cost of information. SIDC and SIFMPC have both maintained a good market position and massive participation in the supply chain of hogs and cacao beans, respectively, enabling them to reap greater economic gains. Based on their financial ratios, the two case cooperatives indicated a desirable profitability, liquidity and solvency. The study concludes that cooperatives can indeed be a viable enterprise model providing enabling conditions for attaining economic efficiency. However, adequate resources and investment capacities to support their market-complementing activities must be ensured in order to perform productively, competitively and sustainably. The success of SIDC and SIFMPC is not replicated by many micro and small cooperatives which are often saddled with limited resources and are unable to undertake efficient business operations.

description: We have used the free expansion of ultracold neutral plasmas as a time-resolved probe of electron temperature. A combination of experimental measurements of the ion expansion velocity and numerical simulations characterize the crossover from an elastic-collision regime at low initial Gamma_e, which is dominated by adiabatic cooling of the electrons, to the regime of high Gamma_e in which inelastic processes drastically heat the electrons. We identify the time scales and relative contributions of various processes, and experimentally show the importance of radiative decay and disorder-induced electron heating for the first time in ultracold neutral plasmas.

CPET's superior ability to measure the global exercise response of the respiratory, cardiovascular and skeletal muscle systems simultaneously in a time and cost-efficient manner has led to the application of CPET in a range of settings from diagnosis of disease to preoperative assessment. The Association for Respiratory Technology and Physiology Statement on Cardiopulmonary Exercise Testing 2021 provides the practitioner and scientist with an outstanding resource to support and enhance practice, from equipment to testing to leadership, helping them deliver a quality assured service for the benefit of all patient groups.
Bio-acoustics of the gray whale (Eschrichtius robustus)
Creators: name: Dahlheim, Marilyn Elayne
Publisher: name: University of British Columbia
Year: 2010

description: Gray whales (Eschrichtius robustus), while engaged in underwater signalling, circumvent noise in the acoustical channel by the structure and timing of their calls. Data yielding this conclusion were collected during an acoustical study on gray whales and their habitats (1981-1984). Sonographic analyses of tape recordings were used to quantify the acoustical repertoire, the ambient noise characteristics of the area, and the relationship between the animals' calls and the environment. The acoustical responses of whales to artificially increased levels of noise were documented during playback experimentation in Mexico. Nine sound parameters were inspected and compared between control and experimental conditions: calling rates, call types, frequency range of signals (Hz), emphasized frequencies (Hz), received levels of sounds (dB re 1 μPa), call duration (sec), percentage of calls exhibiting frequency modulation, number of pulses per series, and repetition rates of signals. The observed surface behavior of gray whales in response to noise (i.e., dive durations, movements and abundance) was also investigated. Analyses yielded: a description of gray whale call types; a characterization of the acoustical habitats occupied by this species, including a list of sources contributing to the ambient noise and a profile of the propagation characteristics of the study area; a determination of the relationship between whale calls and their habitats; and the acoustical capabilities and strategies of whales in response to noise. The plasticity observed in the overall behavior of this whale is of adaptive significance when considering the dynamic nature of noise in the environment. Typically, the multiple strategies employed by the whales when faced with various noise situations enable them to minimize the detrimental effect that noise has on their underwater signalling. Gray whale responses varied with the sound source and may also differ relative to the geographical range and/or general behavior of the animal. It is concluded that ambient noise (both natural and man-made) has a profound effect on the behavior of this coastal species and that acoustical calling is modified to optimize signal transmission and reception.
A Language-Independent Approach to Generating Comprehensive Random Programs
Creators: name: Rodrigues, Melburne
Publisher: name: University of Illinois at Chicago
Year: 2024

description: A vast majority of software running on a computer has been processed by a compiler. Given their ubiquitous nature and critical role in the software development process, ensuring their correctness, reliability, and performance is of great importance, yet writing comprehensive tests for compilers remains a challenge. Manually writing test programs is labor-intensive and prone to biases and errors. While existing test program generators are capable of generating programs with complex statements, they often lack versatility and extensibility across different programming languages. We present GEMCEAS (Grammar Enhanced Monte Carlo Engine for App Simulation), a language-independent approach to generating random programs that serve as benchmarks for testing compilers and other program analysis tools. GEMCEAS accepts an EBNF-style language grammar to ensure the generated programs are syntactically correct, and references a language specification encoded as a Prolog knowledge base for semantic validation. We implement our tool for Java and a simple language for arithmetic expressions, and discuss the results of our experiments in this thesis.

description: In Algeria the energy consumption is based almost exclusively on fossil energy sources, hydrocarbons and especially natural gas. In recent years, Algerian government has shown an ambition to start a new renewable energy (RE) development plan. In this paper, we will present the national programme for the period 2011–2030, which was developed in order to promote concrete actions in the fields of energy efficiency and RE. In fact, it is expected that about 40% of electricity produced for domestic consumption will be from renewable energy sources by 2030.This strategic choice is motivated by the availability of a huge solar potential.
The US$ 120 billion programme, consists of installing up to 22,000MW of power generating capacity from renewable sources between 2011 and 2030, of which 12,000MW will be intended to meet the domestic electricity demand and 10,000MW destined for export.

description: Performing orbital insertion around Mars using aerocapture instead of a propulsive orbit insertion manoeuvre allows to save resources and/or increase the payload mass fraction. Aerocapture has never been employed to date because of the high uncertainties in the parameters from which it depends, mainly related to atmospheric density modeling and navigation errors. The purpose of this work is to investigate the feasibility of aerocapture at Mars with an innovative deployable drag device, whose aperture can be modulated in flight, and assess the effects of the main uncertainties on the success of the manoeuvre. This paper starts with the presentation of a parametric bi-dimensional analysis of the effectiveness of aerocapture, for which a wide range of uncertainty levels in the atmospheric density and the ballistic coefficient are considered. Then, an application to a real mission scenario is carried out including the error of the targeting manoeuvre performed at the limit of the sphere of influence of the planet. The analyses show the strong influence of the uncertainties in the atmospheric density and the ballistic coefficient, which significantly narrow the solution space and limit its continuity. However, viable solutions for aerocapture can still be identified even in the worst conditions.

description: Globally, the deployment of solar energy is becoming increasingly important for developing and emerging economies. Policy makers need to provide policies that not only take into consideration technical performance and economic feasibility, but also social, environmental, and political impacts. Hence assessment of photovoltaic technologies using multiple perspectives such as social, technological, economic, environmental, and political (STEEP) is becoming part of policy framing and rulemaking. Each perspective consists of qualitative and quantitative criteria. A hierarchical decision model using expert judgment quantification was developed earlier for ranking the criteria. The model was operationalized by the use of desirability functions for each criterion. The combined results provide scores for each solar technology alternative under consideration. The results also identify the criteria which require improvements and indicate how much improvement is required. Such modeling for assessing technologies using multiple competing perspectives and criteria is being accepted for its effectiveness and flexibility. In earlier research the electric utility worldview was considered to assess multiple photovoltaic technologies. This paper is a case study of a national policy makers worldview. Parallel research was completed for the solar photovoltaic manufacturer worldview.

description: Efficient water electrolyzers are constrained by the lack of low-cost and earth-abundant hydrogen evolution reaction (HER) catalysts that can operate at industry-level conditions and be prepared with a facile process. Here we report a self-standing MoC-Mo2C catalytic electrode prepared via a one-step electro-carbiding approach using CO2 as the feedstock. The outstanding HER performances of the MoC-Mo2C electrode with low overpotentials at 500 mA cm-2 in both acidic (256 mV) and alkaline electrolytes (292 mV), long-lasting lifetime of over 2400 h (100 d), and high-temperature performance (70 oC) are due to the self-standing hydrophilic porous surface, intrinsic mechanical strength and self-grown MoC (001)-Mo2C (101) heterojunctions that have a ΔGH* value of -0.13 eV in acidic condition, and the energy barrier of 1.15 eV for water dissociation in alkaline solution. The preparation of a large electrode (3 cm × 11.5 cm) demonstrates the possibility of scaling up this process to prepare various carbide electrodes with rationally designed structures, tunable compositions, and favorable properties.

description: The Per OB1 association, which contains the remarkable double cluster h and chi Per, is unusual in not having a giant molecular cloud in its vicinity. We show from Hipparcos data that the luminous members of this association exhibits a bulk motion away from the galactic plane, such that their average velocity increases with height above the galactic plane. We find HAeBe and T Tauri stars towards probable remnant molecular clouds associated with Per OB1. These star-forming regions lie well beyond the location of the luminous member stars at heights of 280-400 pc above the galactic plane, far higher than that previously found for embedded clusters. We argue that the observed motion of the luminous member stars is most naturally explained if many formed from molecular gas pushed and accelerated outwards by an expanding superbubble driven presumably by stellar winds and perhaps also supernova explosions. A large shell of atomic hydrogen gas and dust that lies just beyond the remnant molecular clouds, believed to be driven by just such a superbubble, may comprise the swept-up remains of the parental giant molecular cloud from which this association formed. In support of this picture, we find a week trend for the younger O star members to lie at higher galactic latitudes than the older supergiant members. The star-forming regions located at even larger heights above the galactic plane presumably correspond to more recent episodes of star formation at or near the periphery of this superbubble.

description: We simulate the growth of a dual species Bose-Einstein condensate using a Gross-Pitaevskii equation with an additional gain term giving rise to the growth. Such growth occurs during simultaneous evaporative cooling of a mixture of two gases. The ground state of a dual condensate is normally either a miscible mixture, or an immiscible phase with two spatially separated components. In a cigar trap the ground state typically consists of one component in the center, and the other component flanking it. Our simulations show that when the condensates are formed in a cigar trap and the mixture is phase separated, then the final state upon the end of the growth is generally far from the true ground state of the system. Instead it consists of multiple, interleaved bubbles of the two species. Such a pattern was observed recently in an experiment by Wieman's group at JILA, and our simulations are in good qualitative agreement with the experiment. We explain the pattern formation as due to the onset of modulation instability during growth, and study the dependence of the final state pattern on various parameters of the system.
A discussion on particle number and quantum indistinguishability

description: The concept of individuality in quantum mechanics shows radical differences from the concept of individuality in classical physics, as E. Schroedinger pointed out in the early steps of the theory. Regarding this fact, some authors suggested that quantum mechanics does not possess its own language, and therefore, quantum indistinguishability is not incorporated in the theory from the beginning. Nevertheless, it is possible to represent the idea of quantum indistinguishability with a first order language using quasiset theory (Q). In this work, we show that Q cannot capture one of the most important features of quantum non individuality, which is the fact that there are quantum systems for which particle number is not well defined. An axiomatic variant of Q, in which quasicardinal is not a primitive concept (for a kind of quasisets called finite quasisets), is also given. This result encourages the searching of theories in which the quasicardinal, being a secondary concept, stands undefined for some quasisets, besides showing explicitly that in a set theory about collections of truly indistinguishable entities, the quasicardinal needs not necessarily be a primitive concept.

description: The V3 loop of the HIV-1 envelope (Env) protein elicits a vigorous, but largely non-neutralizing antibody response directed to the V3-crown, whereas rare broadly neutralizing antibodies (bnAbs) target the V3-base. Challenging this view, we present V3-crown directed broadly neutralizing Designed Ankyrin Repeat Proteins (bnDs) matching the breadth of V3-base bnAbs. While most bnAbs target prefusion Env, V3-crown bnDs bind open Env conformations triggered by CD4 engagement. BnDs achieve breadth by focusing on highly conserved residues that are accessible in two distinct V3 conformations, one of which resembles CCR5-bound V3. We further show that these V3-crown conformations can, in principle, be attacked by antibodies. Supporting this conclusion, analysis of antibody binding activity in the Swiss 4.5 K HIV-1 cohort (n = 4,281) revealed a co-evolution of V3-crown reactivities and neutralization breadth. Our results indicate a role of V3-crown responses and its conformational preferences in bnAb development to be considered in preventive and therapeutic approaches.
Comparing DMFS Scores and Recall Compliance in Infants before and During the Covid-19 Pandemic

description: Hypothesis and Objective: COVID-19 led to a decline in regular preventive healthcare utilization. This study hypothesized an increase in dental caries in infants during COVID-19 compared to pre-pandemic levels. The study aimed to (1) compare caries prevalence in infants using dmfs (decayed, missing, filled surfaces) scores before and during COVID-19; (2) evaluate recall compliance; (3) assess the need for emergent dental and Silver Diamine Fluoride (SDF) treatment; and (4) determine the need of treatment under general anesthesia (GA).
Methods: A retrospective study was conducted for infants presenting for initial visits in 2019 and 2021. We reviewed all children who presented to UIC in 2019 (n=128) and matched that sample size for review in 2021. Patient demographics, age at initial appointment, dmfs score, need emergency treatment and SDF, recall compliance, and need of treatment under GA were analyzed using univariate and Chi-Square analysis.
Results: The mean dmfs percentages were 4.69% and 9.08% in 2019 and 2021 respectively, without significant statistical difference. The average age at first visit was 22 and 24 months in 2019 and 2021, respectively. Post-COVID, 57% infants required SDF application, significantly higher than the 34% pre-COVID (p< 0.05). GA necessity increased from 14% in 2019 to 23% in 2021. Recall compliance was 33% in both groups.
Conclusions: Most infants presented closer to age 2 for their first visit. Findings suggest an increase in caries prevalence in the wake of the pandemic, with a significant increase in SDF use to manage caries and delay comprehensive treatment, usually under GA.

description: In this paper, we construct several kinds of new time-periodic solutions of the vacuum Einstein's field equations whose Riemann curvature tensors vanish, keep finite or take the infinity at some points in these space-times, respectively. The singularities of these new time-periodic solutions are investigated and some new physical phenomena are found. The applications of these solutions in modern cosmology and general relativity can be expected.

description: The binary of the pulsar PSRB1259$-$63 and the Be star LS 2883 has been observed at the 2010 and 2014 periastron passages in the near-infrared (NIR) bands using the IRSF/SIRIUS and SIRPOL. The light curves in the J-,H-, and Ks-bands are almost identical in these periastron passages. A flare starts no later than 10 days before periastron and the maximum brightening of about 0.1 magnitude is observed 12--17 days after periastron. The rising part of the light curve is steeper and reaches a peak slightly earlier in the Ks-band than in the other bands, thus a characteristic track appears on the NIR color-magnitude diagram. The time lag between the NIR light curves indicates that the variation in the Be circumstellar disk first occurs in an outer region. We propose that the initial rapid contraction followed by the gradual expansion of the disk is evoked by the rapidly changing tidal torque around periastron and the resultant change of the optically thick area causes the observed NIR light curves.

Colloidal Gels: Equilibrium and Non-Equilibrium Routes
Creators: name: Zaccarelli, Emanuela
Publisher: name: arXiv
Year: 2007
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We attempt a classification of different colloidal gels based on colloid-colloid interactions. We discriminate primarily between non-equilibrium and equilibrium routes to gelation, the former case being slaved to thermodynamic phase separation while the latter is individuated in the framework of competing interactions and of patchy colloids. Emphasis is put on recent numerical simulations of colloidal gelation and their connection to experiments. Finally we underline typical signatures of different gel types, to be looked in more details in experiments.

description: The Department of Science and Technology (DOST) initiated the Small Enterprise Technology Upgrading Program (SETUP) to provide assistance to micro, small and medium enterprises (MSMEs) through technological innovations. From 2002 to 2010, 51 projects in CALABARZON availed of the SETUP assistance mainly for the acquisition of production equipment. This study assesses the performance of MSMEs which focused on the achievement of the target level of improvement and identified the factors that affected the achievement or non-achievement of the target. The target differs for every firm and depends on the technological intervention identified during the conduct of Technology Needs Assessment (TNA). Results show that within the short term (i.e., one year after the availment of assistance), more than half of the firms in the food/beverage and furniture/ GTH achieved their target. In the medium term (2–3 years), the furniture/GTH sector successfully achieved its target with contributory factors such as innovation, production efficiency and good working condition. The food/beverage and metals/engineering sectors were not as successful due to the decrease in market demand and lack of working capital. In the long term (4 years and longer), the food and beverage sector had achieved the target level of improvement but the metals and engineering sector as well as the furniture and GTH sectors apparently failed. External factors such as 2007-2009 global economic crises and typhoons contribute to the failure of the SETUP-assisted projects. All in all, SETUP is deemed as successful in encouraging and assisting MSMEs to adopt technological innovations that improve their operation and productivity; however, internal and external factors affect the ability of MSMEs to achieve their target level of improvement.

description: An expansion of row Markov matrices in terms of matrices related to permutations with repetitions, is introduced.It generalises the Birkhoff-von Neumann expansion of doubly stochastic matrices in terms of permutation matrices (without repetitions).An interpretation of the formalism in terms of sequences of integers that open random safes described by the Markov matrices, is presented. Various quantities that describe probabilities and correlations in this context, are discussed. The Gini index is used to quantify the sparsity (certainty) of various probability vectors. The formalism is used in the context of multipartite quantum systems with finite dimensional Hilbert space, which can be viewed as quantum permutations with repetitions or as quantum safes. The scalar product of row Markov matrices, the various Gini indices, etc, are novel probabilistic quantities that describe the statistics of multipartite quantum systems. Local and global Fourier transforms are used to define locally dual and also globally dual statistical quantities. The latter depend on off-diagonal elements that entangle (in general) the various components of the system. Examples which demonstrate these ideas are also presented.

description: We consider optimal investment problems for a diffusion market model with non-observable random drifts that evolve as an Ito's process. Admissible strategies do not use direct observations of the market parameters, but rather use historical stock prices. For a non-linear problem with a general performance criterion, the optimal portfolio strategy is expressed via the solution of a scalar minimization problem and a linear parabolic equation with coefficients generated by the Kalman filter.

Silicon Solar Cell Improvements

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 908-910
description: In this work, we demonstrate an improvement of c-Si solar cell properties by using concept of threedimensional
(3D) c-Si solar cell technology that results in an enhancement of the conversion of the sun light into the
electric current. Technological method for concept realization is based on the p-n junction that is formed on the textured
side of the substrate by the diffusion assisted doping from the phosphosilicate glass. Before doping an array of nanoholes,
nano-cones or nano-hills is fabricated by electrochemical and chemical etching of the p-Si substrate. In this work, a
relationship between the technological conditions and the fundamental properties of the cells is investigated. An
influence of the etching conditions on the cell structure, the junction formation and the electrical parameters is discussed.
