description: This paper presents a performance evaluation of Wireless Sensor Networks (WSN) based on Impulse Radio Ultra Wideband (IR-UWB) over a new simulation platform developed for this purpose. The simulation platform is built on an existing network simulator: Global Mobile Information System Simulator (GloMoSim). It mainly focuses on the accurately modeling of IR-UWB PHYsical (PHY) and Medium Access Control (MAC) layer. Pulse collision is modeled according to the used time hopping sequence (THS) and the pulse propagation delay in order to increase the simulation fidelity. It also includes a detection and identification application based on a new sensing channel and new sensor device models. The proposed architecture is generic so it can be reused for any simulation platform. The performance evaluation is based on one of the typical WSN applications: local area protection, where sensor nodes are densely scattered in an access regulated area in order to detect, identify and report non authorized accesses to a base station for analysis. Two networks topologies using different protocol stacks are investigated. Their performance evaluation is presented in terms of reliability and latency.
title: A Mechanistic Study of Catalytic Promiscuity in Protein Phosphatase 1

description: "Catalytic promiscuous" enzymes, which possess additional activities besides their "native" activity, albeit with a lower efficiency than the main reaction, have become a new frontier for biochemistry and have received considerable attention. Catalytic promiscuity has been suggested to contribute to enzyme evolution through the mechanism of gene duplication followed by specialization of one of the two copies for the new function. Mimicking this evolutionary shortcut could also provide a more efficient route to changing the function of proteins by directed evolution. The promiscuous phosphatase PP1 is a member of the phosphoprotein phosphatase (PPP) gene family, which is critical for the control of many cellular pathways by antagonizing the effects of protein phosphorylation mediated by kinases. The catalytic promiscuity of PP1&gamma WT and two mutants has been investigated with a set of monoanionic and dianioic phosphester substrates. PP1&gamma is an effective catalyst for the hydrolysis of both monoanionic and dianionic phosphate-ester based substrates 1-5, with second-order rate accelerations that fall within the narrow range of 1011 to 1013. While the transition states of the uncatalyzed hydrolysis reactions of these substrates differ, those for the PP1&gamma-catalyzed reactions are similar. Thus, the enzyme catalyzes the hydrolysis of these substrates by transition states that are controlled by the active site environment more than by the intrinsic nature of the substrates. The reason for the inability of PP1&gamma to catalyze the hydrolysis of a sulfate ester is unclear, and unexpected, since the charge and transition state of this substrate are well within the range of those of the phosphorus-based substrates that are effectively catalyzed. Inhibition experiments suggest that the PP1&gamma active site is tolerant of variations in the geometry of bound ligands. This characteristic may permit the effective catalysis even of substrates whose steric requirements may result in perturbations to the positioning of the transferring group, both in the initial enzyme-substrate complex and in the transition state. The conservative mutation of arginine 221 to lysine results in a mutant that more effectively catalyzes monoanionic substrates than the native enzyme. The surprising result in substrate preference from a single, conservative mutation lends support to the notion that mutations following gene duplication can result in an altered enzyme with different catalytic capabilities and preferences, and may, following subsequent mutations, provide a pathway for the evolution of new enzymes.

description: The development of engineered skeletal muscle tissues has recently been proposed as a potential solution for replacement of volumetric muscle losses. Experimental studies available in literature have mainly been performed in animals. The aim of the present work was to evaluate the possibility of obtaining homologous acellular scaffolds from decellularization of human skeletal muscle, also through a comparison with rats and rabbits, and evaluating the capability of muscle scaffolds to repair defects of the abdominal wall. Muscle samples of rats, rabbits and humans were treated with two different decellularization methods. Surgical tests were also performed in rabbits, implanting the decellularized scaffold in the abdominal wall of animal with surgical defects of the abdominal wall. Human skeletal muscles were sampled from body parts removed during surgery and given to the Body Donation Program of the Institute of Human Anatomy of the University of Padua. Histological stainings confirmed the effectiveness of decellularization, resulting in cell-free scaffolds with no residual cells in the matrix. The complex three-dimensional networks of collagen (azan-Mallory) and elastic fibers (Van Gieson) were maintained, in the absence of nuclear material (DAPI staining and DNA extraction/quantification). Ultrastructural analyses with transmission and scanning electron microscopy also showed the preservation of collagen and elastic fibres, together with proteoglycan components. The vascular structures in the tissue were also still visible, with preservation of collagen and elastic wall components and loss of endothelial (anti-CD31 and –CD34 immunohistochemistry) and smooth muscle (anti-alpha smooth muscle actin) cells. Scaffold implantations in rabbits gave good results in terms of integration with surrounding structures (in vivo US analyses and post mortem macro/ microscopic analyses), although recellularization by surrounding muscle cells was not satisfactory. In conclusion, not only animal (rat and rabbit) skeletal muscles but also human samples may be decellularized to obtain complex 3D scaffolds preserving tissue architecture potentially suitable for recellularization. In rabbits, these scaffolds have maintained some biomechanical properties once implanted, although spontaneous recellularization was not achieved. Further analyses will be necessary to verify the possibility of in vitro recolonization of scaffolds by homologous myoblasts and autologous satellite cells, before in vivo re-implantation.

description: Two different cell lines - MLO-Y4 (murine osteocytes) and 293 (human fibroblasts) - cultured for 48 hours in standard media were used to analyse engineered biomaterials (i.e. Al2O3 shot-peened titanium surfaces). Distribution, density and expression of adhesion molecules (fibronectin and vitronectin) were evaluated under scanning electron microscope (SEM) and confocal microscope (CM) as previously described [1]. The engineered biomaterial surfaces showed under SEM irregular morphology displaying variously-shaped spicules, obtained by shooting different-in-size particles of Al2O3 against the scaffolds of biomaterial. DAPI and fluorochrome-conjugated antibodies were used to highlight nuclei, fibronectin and vitronectin, under CM; cell distribution was analysed after Gold-Palladium sputtering of samples by SEM. Both SEM and CM observations showed better outcome in terms of cell adhesion and distribution in treated titanium surfaces with respect to the untreated ones. The results obtained clearly showed that this kind of surface-treated titanium, used to manufacture devices for dental implantology: i) is very suitable for cell colonization, essential prerequisite for the best osseointegration, and ii) represents an excellent solution for the development of further engineered implants with the target to obtain recovery of dental function stable over time. Further studies on these Al2O3 shot-peened-titanium surfaces, both in vitro and in vivo, will be needed to obtain accurate definition of better biomaterial outcome, also after additional treatments.

description: The sigma model on complex projective superspaces CP^{S-1|S} gives rise to a continuous family of interacting 2D conformal field theories which are parametrized by the curvature radius R and the theta angle θ. Our main goal is to determine the spectrum of the model, non-perturbatively as a function of both parameters. We succeed to do so for all open boundary conditions preserving the full global symmetry of the model. In string theory parlor, these correspond to volume filling branes that are equipped with a monopole line bundle and connection. The paper consists of two parts. In the first part, we approach the problem within the continuum formulation. Combining combinatorial arguments with perturbative studies and some simple free field calculations, we determine a closed formula for the partition function of the theory. This is then tested numerically in the second part. There we propose a spin chain regularization of the CP^{S-1|S} model with open boundary conditions and use it to determine the spectrum at the conformal fixed point. The numerical results are in remarkable agreement with the continuum analysis.

description: Erbium doped materials are of great interest in optical telecommunications due to the Er3+ intra-4f emission at 1.54 ?m. Erbium doped fibre amplifiers (EDFA) were developed in silica glass because of the low losses at this wavelength and the reliability of this glass. Developments of new rare earth doped fibre amplifiers aim to control their spectroscopic properties including shape and width of the gain curve and optical quantum efficiency. Standard silica glass modifiers, such as aluminium, result in very good properties in current EDFA. However, for more drastic spectroscopic changes, more important modifications of the rare earth ions local environment are required. To address this aim, we present a fibre fabrication route creating rare earth doped calcia?silica or calcia?phosphosilica nanoparticles embedded in silica glass. By adding alkaline earth elements such as calcium, in low concentration, one can obtain a glass with an immisci- bility gap so that phase separation occurs with an appropriate heat treatment. We investigated the role of two elements: calcium and phosphorus (a standard silica modifier). Scanning electron microscopy shows that nanoparticles are only observed when calcium is incorporated. The size of the particles is determined to be around 50 nm in preform samples. The nature of these particles depends on phosphorus content: without P, electron diffraction shows that the particles are amorphous whilst they are partially crystalline when phosphorus is added. In addition through use of energy dispersive x-ray techniques, we have shown that erbium ions are located in the nanoparticles.

title: Drivers of Nest Success and Stochastic Population Dynamics of the Common Eider (Somateria mollissima)

description: Anthropogenic perturbations to Arctic ecosystems have influenced large-scale climate processes, as well as finer-scale ecological relationships within and amongst populations of species. Life history theory predicts a trade-off between the temporal variation in a vital rate and its impact on population dynamics. Here, we examine the drivers of long-term variation in reproductive success in a sub-Arctic common eider (Somateria mollissima) colony, and evaluate the impacts of variation in reproductive success on eider population dynamics. In Chapter 2, we develop a suite of nest survival models to evaluate the effects of variation in predator abundance, the availability and spatial distribution of alternative prey, and breeding season climate on annual common eider nest success. Eider nest success declined across the 41 years of study, but was also highly variable across years. Annual variation in nest success was driven by a complex interaction between predators and alternative prey, as well as breeding season climate. Our results suggest that increased abundance of snow geese (alternative prey) may buffer annual fluctuations in arctic fox abundance, yet result in a long-term decline in eider nest success suggesting apparent competition via other predator species (e.g. gulls). The effect of breeding season climate was subtle compared to the influence of biotic factors and indicated that cold, wet conditions in early spring were correlated with decreased nest success, while warm, wet conditions in late spring increased eider nest success. In Chapter 3 we develop a stochastic population model to evaluate the relative effects of variation and covariation amongst multiple vital rates on population dynamics, and determine the impact of long-term changes in the abundance of alternative prey on eider population dynamics. Consistent with life history predictions, we found that proportional changes in adult survival have the largest impact on population dynamics, yet high variation in the vital rates underlying fertility contribute more to actual variation in population growth. The eventual exodus of alternative prey from the eider colony reduced the long-term growth rate, primarily through negative impacts on mean nest success.

description: The BeppoSAX Catalog has been very recently published. In this paper we analyze - using the Maximum Likelihood (ML) method - the duration distribution of the 1003 GRBs listed in the catalog with duration. The ML method can identify the long and the intermediate duration groups. The short population of the bursts is identified only at a 96% significance level. MC simulation has been also applied and gives a similar significance level; 95%. However, the existence of the short bursts is not a scientific question after the Compton Gamma-Ray Observatory's observation. Our minor result is this well-known fact that in the BeppoSAX data the short bursts are underrepresented, mainly caused by the different triggering system. Our major result is the identification of the intermediate group in the BeppoSAX data. Therefore, four different satellites (CGRO, Swift, RHESSI and BeppoSAX) observed the intermediate type Gamma-Ray Burst.

description: We propose a novel robotic system that can improve its perception during deployment. Contrary to the established approach of learning semantics from large datasets and deploying fixed models, we propose a framework in which semantic models are continuously updated on the robot to adapt to the deployment environments. By combining continual learning with self-supervision, our robotic system learns online during deployment without external supervision. We conduct real-world experiments with robots localising in 3D floorplans. Our experiments show how the robot's semantic perception improves during deployment and how this translates into improved localisation, even across drastically different environments. We further study the risk of catastrophic forgetting that such a continuous learning setting poses. We find memory replay an effective measure to reduce forgetting and show how the robotic system can improve even when switching between different environments. On average, our system improves by 60% in segmentation and 10% in localisation accuracy compared to deployment of a fixed model, and it maintains this improvement while adapting to further environments.

description: We take advantage of the very simple morphology of RCW 120 -- a perfect bubble -- to understand the mechanisms triggering star formation around an HII region and to establish what kind of stars are formed there. We present 870 microns observations of RCW 120, obtained with the APEX-LABOCA camera. These show the distribution of cold dust, and thus of neutral material. We use Spitzer-MIPS observations at 24 and 70 microns to detect the young stellar objects (YSOs) present in this region and to estimate their evolutionary stages. A layer of dense neutral material surrounds the HII region, having been swept up during the region's expansion. This layer has a mass greater than 2000 solar masses and is fragmented, with massive fragments elongated along the ionization front (IF). We measured the 24 microns flux of 138 sources. Of these, 39 are Class I or flat-spectrum YSOs observed in the direction of the collected layer. We show that several triggering mechanisms are acting simultaneously in the swept-up shell, where they form a second generation of stars. No massive YSOs are detected. However, a massive, compact 870 microns core lies adjacent to the IF. A 70 microns source with no 24 microns counterpart is detected at the same position. This source is a likely candidate for a Class 0 YSO. Also at 24 microns, we detect a chain of about ten regularly spaced Class I or flat spectrum sources, parallel to the IF, in the direction of the most massive fragment. We suggest that the formation of these YSOs is the result of Jeans gravitational instabilities in the collected layer. Finally, the 870 microns emission, the 24 microns emission, and the Halpha emission show the existence of an extended and partially ionized photodissociation region around RCW 120.

description: Abstract

The purpose of this study is to create maps that identify potential sites for rainwater harvesting techniques (RWHT) in South Darfur State (SDS), using the Nyala basin as a case study. The basin experiences flash floods, which generate significant amounts of runoff. The RWHTs aim to conserve and maximize the available water resources in order to improve crop productivity. After conducting a literature review and consulting with experts in the field, seven RWHTs were selected for the study: runoff basin system, contour furrows, and flat, flood, pond, check dam, on-farm pond, and bench terraces. The data analysis was carried out in the ArcGIS environment and involved spatial analysis and data re-classification, supported by multi-criteria analysis. The multi-criteria analysis consisted of five selection criteria (rainfall, runoff, land use, slope, and soil texture), each with sub-indicators to assign relative weight for each RWHT. These selection criteria were based on an extensive literature review and five expert-based surveys that assessed the impacts of RWHT on the study area using an Analytic Hierarchy Process (AHP). The consistency ratio between the experts' opinions was evaluated using the pair-wise comparison. Final weights were computed for each criterion, and the method of spatial analysis and data re-classification was employed to generate the required suitability maps. The results show that runoff basin systems are recommended for use in the southwest high-rain parts of SDS, and it is the most suitable technique for about 30% of the area of SDS. Contour furrows, flat and terrace techniques are highly suitable for 70% of the state area with moderate rainfall to grow pasture. Flooding techniques are not recommended except in the high rainfall southern areas near Bahr El Arab. The check dam and pond techniques are suitable in the middle to the southern areas that are occupied by small surface streams running towards Bahr El Arab. Farm ponds or flooding techniques are not suitable for Debla's hilly areas or the northern areas with low rainfall. For the Jabal Mara area, it is recommended to employ bench terraces. Overall, this approach can help decision-makers efficiently plan water resource management in arid dry areas suffering from water shortages, ensuring sustainable development of water resources.

description: Non alcoholic fatty liver disease (NAFLD) impacts on about 30% of the population in industrialized countries, associated to the metabolic syndrome may be reversible or dramatically evolve into cirrhosis or hepatocellular cancer (Wree et al., 2011). Leptin-deficient homozygous mice (ob/ob) represent a well-known animal model to study obesity, associated with overweight, liver steatosis and insulinresistance. Recently ER stress has been reported to contribute to hepatic steatosis and cell damage called lipoapoptosis (Flamment et al., 2010). Melatonin, the main pineal indoleamine, has been demonstrated to be useful to limit adipogenesis in many metabolic clinical conditions (de Luxan-Delgado et al., 2014). Therefore major aims of the present study were: 1.To localize ER stress, energy homeostasis and hypoxia markers in the liver of ob/ob mice receiving or not melatonin in drinking water at 100 mg/ kg/day for 8 weeks; 2.To characterize hepatic steatosis and quantify macrosteatosis in different experimental groups. C57BL6 mice treated or not with melatonin were used as controls. Remarkably in ob/ob mice receiving melatonin, macrosteatosis, periportal GRP78 staining decreased while beta catenin became basolateral into hepatocytes. Furthermore melatonin limited nuclear CHOP staining, a recognized index of major sensitivity to apoptosis, but stimulated p62/SQSTM1 signal, involved in reducing lipogenesis. Moreover by TEM analysis, we visualized in ob/ob mice liver mitochondria that displayed more cristae and strict RER adhesion after melatonin intake. In conclusion, our morphological analysis suggests that melatonin might ameliorate NAFLD by anti-oxidative and ER stress modulatory abilities in obese mice.

title: Statistical Methods for Launch Vehicle Guidance, Navigation, and Control (GN&C) System Design and Analysis
Creators: name: Rose, Michael Benjamin
Publisher: name: Utah State University
Year: 2012

description: A novel trajectory and attitude control and navigation analysis tool for powered ascent is developed. The tool is capable of rapid trade-space analysis and is designed to ultimately reduce turnaround time for launch vehicle design, mission planning, and redesign work. It is streamlined to quickly determine trajectory and attitude control dispersions, propellant dispersions, orbit insertion dispersions, and navigation errors and their sensitivities to sensor errors, actuator execution uncertainties, and random disturbances. The tool is developed by applying both Monte Carlo and linear covariance analysis techniques to a closed-loop, launch vehicle guidance, navigation, and control (GN&C) system. The nonlinear dynamics and flight GN&C software models of a closed-loop, six-degree-of-freedom (6-DOF), Monte Carlo simulation are formulated and developed. The nominal reference trajectory (NRT) for the proposed lunar ascent trajectory is defined and generated. The Monte Carlo truth models and GN&C algorithms are linearized about the NRT, the linear covariance equations are formulated, and the linear covariance simulation is developed. The performance of the launch vehicle GN&C system is evaluated using both Monte Carlo and linear covariance techniques and their trajectory and attitude control dispersion, propellant dispersion, orbit insertion dispersion, and navigation error results are validated and compared. Statistical results from linear covariance analysis are generally within 10% of Monte Carlo results, and in most cases the differences are less than 5%. This is an excellent result given the many complex nonlinearities that are embedded in the ascent GN&C problem. Moreover, the real value of this tool lies in its speed, where the linear covariance simulation is 1036.62 times faster than the Monte Carlo simulation. Although the application and results presented are for a lunar, single-stage-to-orbit (SSTO), ascent vehicle, the tools, techniques, and mathematical formulations that are discussed are applicable to ascent on Earth or other planets as well as other rocket-powered systems such as sounding rockets and ballistic missiles.

description: Одна из сфер в современном обществе, сильно изменяющаяся в связи с цифровизацией, — индустрия моды. Развитие новых технологий, пандемия коронавируса и закрытие физических магазинов привели к появлению феномена цифровой моды. Данный феномен является частью более обширного направления под названием Fashion Tech. Fashion Tech — это новая индустрия, созданная на стыке моды и современных инновационных технологий. В данной работе описаны изменения на рынке профессий и требований к работе дизайнеров, а также выявлены особенности взаимодействия социального пространства с виртуальной реальностью, что потребовало введения понятия «гибридной реальности». Эмпирическое исследование мнений дизайнеров позволило определить универсальные и узконаправленные практики взаимодействия с цифровой модой. Описаны проблемные аспекты в развитии и популяризации цифровой моды, такие как недостаточная техническая оснащенность и отсутствие единой платформы для использования виртуальных предметов гардероба, а также низкий уровень информированности людей о данном феномене. Цифровая мода определяется как феномен, который может стать источником вдохновения и диктатором тенденций для дизайнеров физического мира, создавать перспективы для самореализации и коммерциализации в виртуальном пространстве. Автор старался дать как можно более полное представление о феномене цифровой моды и его влиянии на современное общество, а также определить возможные направления его развития.

description: Dingle Marsh is a wetland complex separating the Bear River from Bear Lake. Flow direction through the marsh is controlled at four major inflow and outflow sites. These sites were chosen as monitoring sites to assess the suspended solid and nutrient transport through the marsh. High frequency turbidity measurements were collected at each site and used as a surrogate for total phosphorus (TP) and total suspended solid (TSS) concentrations. Loads of TP and TSS were calculated using flow data from the 2008 water year. Load calculations for TP and TSS were compiled at 30-minute intervals and annual mass balances were calculated for Dingle Marsh and Bear Lake. These calculations were used to identify the seasonal loading patterns within this system. This study found the majority of TSS and TP loading entered the marsh from the Bear River. As flows moved across the marsh, the loading of TSS and TP was greatly reduced. Seasonal flow patterns were analyzed to determine the loading patterns to Dingle Marsh, Bear Lake, and the Bear River. This study also identified water management strategies aimed at setting a target endpoint for TSS and TP loads.
Clustered star formation as a natural explanation of the Halpha cutoff in disc galaxies

description: Star formation is mainly determined by the observation of H$α$ radiation which is related to the presence of short lived massive stars. Disc galaxies show a strong cutoff in H$α$ radiation at a certain galactocentric distance which has led to the conclusion that star formation is suppressed in the outer regions of disc galaxies. This is seemingly in contradiction to recent UV observations (Boissier et al., 2007) that imply disc galaxies to have star formation beyond the Halpha cutoff and that the star-formation-surface density is linearly related to the underlying gas surface density being shallower than derived from Halpha luminosities (Kennicutt, 1998). In a galaxy-wide formulation the clustered nature of star formation has recently led to the insight that the total galactic Halpha luminosity is non-linearly related to the galaxy-wide star formation rate (Pflamm-Altenburg et al., 2007d). Here we show that a local formulation of the concept of clustered star formation naturally leads to a steeper radial decrease of the Halpha surface luminosity than the star-formation-rate surface density in quantitative agreement with the observations, and that the observed Halpha cutoff arises naturally.

description: We study fluctuations of the conductance of micron-sized graphene devices as a function of the Fermi energy and magnetic field. The fluctuations are studied in combination with analysis of weak localization which is determined by the same scattering mechanisms. It is shown that the variance of conductance fluctuations depends not only on inelastic scattering that controls dephasing but also on elastic scattering. In particular, contrary to its effect on weak localization, strong intervalley scattering suppresses conductance fluctuations in graphene. The correlation energy, however, is independent of the details of elastic scattering and can be used to determine the electron temperature of graphene structures.
