description: Fabrication of custom-built heterostructures based on stacked 2D materials provides an effective method to controllably tune electronic and optical properties. To that end, optimizing fabrication techniques for building these heterostructures is imperative. A common challenge in layer-by-layer assembly of 2D materials is the formation of bubbles at the atomically thin interfaces. We propose a technique for addressing this issue by removing the bubbles formed at the heterostructure interface in a custom-defined area using the heat generated by a laser, equipped with raster scanning capabilities. We demonstrate that the density of bubbles formed at graphene-ReS2 interfaces can be controllably reduced using this method. We discuss an understanding of the flattening mechanism by considering the interplay of interface thermal conductivities and adhesion energies between two atomically thin 2D materials.
Density functional theory for hard-sphere mixtures: the White-Bear version Mark II

description: In the spirit of the White-Bear version of fundamental measure theory we derive a new density functional for hard-sphere mixtures which is based on a recent mixture extension of the Carnahan-Starling equation of state. In addition to the capability to predict inhomogeneous density distributions very accurately, like the original White-Bear version, the new functional improves upon consistency with an exact scaled-particle theory relation in the case of the pure fluid. We examine consistency in detail within the context of morphological thermodynamics. Interestingly, for the pure fluid the degree of consistency of the new version is not only higher than for the original White-Bear version but also higher than for Rosenfeld's original fundamental measure theory.

description: WEAVE is the new wide-field spectroscopy facility for the prime focus of the William Herschel Telescope at La Palma, Spain. Its fibre positioner is essential for the accurate placement of the spectrograph's 960 fibre multiplex. We provide an overview of the final assembly and metrology of the fibre positioner, and results of lab commissioning of its robot gantries. A completely new z-gantry for each positioner robot was acquired, with measurements showing a marked improvement in positioning repeatability. We also present the first results of the configuration software testing, and discuss the metrology procedures that must be repeated after the positioner's arrival at the observatory.

description: We study the numerical implementation of a set of boundary conditions derived from the isolated horizon formalism, and which characterize a black hole whose horizon is in quasi-equilibrium. More precisely, we enforce these geometrical prescriptions as inner boundary conditions on an excised sphere, in the numerical resolution of the Conformal Thin Sandwich equations. As main results, we firstly establish the consistency of including in the set of boundary conditions a "constant surface gravity" prescription, interpretable as a lapse boundary condition, and secondly we assess how the prescriptions presented recently by Dain et al. for guaranteeing the well-posedness of the Conformal Transverse Traceless equations with quasi-equilibrium horizon conditions extend to the Conformal Thin Sandwich elliptic system. As a consequence of the latter analysis, we discuss the freedom of prescribing the expansion associated with the ingoing null normal at the horizon.

description: We investigate a mathematical theory for the erosion of sediment which begins with the study of a non-linear, parabolic, weighted 4-Laplace equation on a rectangular domain corresponding to a base segment of an extended landscape. Imposing natural boundary conditions, we show that the equation admits entropy solutions and prove regularity and uniqueness of weak solutions when they exist. We then investigate a particular class of weak solutions studied in previous work of the first author and produce numerical simulations of these solutions. After introducing an optimal transportation problem for the sediment flow, we show that this class of weak solutions implements the optimal transportation of the sediment.

Guided autobiography for older adults

description: Guided autobiography for older adults is a promising tool for helpers interested in working with this population. Outlined by Birren & Deutchman (1991) this method of group work enables older adults to reflect on and review life as lived through sharing written reflections in a confidential small group setting. An ethnographic case study was designed to better illuminate how guided autobiography impacts older adults and to help determine whether it is a promising group design for counsellors and other professionals working with older adults. Seven older adults from West Vancouver participated in a guided autobiography group using Birren & Deutchman's (1991) methodology, focusing on the theme, "the major branching points of life". After the completion of the group each participant was interviewed individually. The interviews were audio-taped, transcribed and then analyzed for evidence of the outcomes reported by Birren & Deutchman (1991). Evidence was found in support of the following outcomes: reconciliation with the past and resolution of past resentments and negative feelings; resurgence of interest in past activities or hobbies; development of friendships with other group members. No evidence was found in support of these outcomes: sense of increased personal power and importance; recognition of past adaptive strategies and application to current needs and problems; greater sense of meaning in life. New outcomes were identified as: recognition that one's life is not yet completed; satisfaction with one's life course; a new perspective and/or appreciation of one's life through comparison with others; and a new awareness or heightened awareness of one's contributions and/or abilities.

description: This paper introduces the notion of exponential arcs in Hilbert space and of exponential arcs connecting vector states on a sigma-finite von Neumann algebra in its standard representation. Results from Tomita-Takesaki theory form an essential ingredient. Starting point is a non-commutative Radon-Nikodym theorem that involves positive operators affiliated with the commutant algebra. It is shown that exponential arcs are differentiable and that parts of an exponential arc are again exponential arcs. Special cases of probability theory and of quantum probability are used to illustrate the approach.

description: We revisit the important issue of charge fluctuations in the two-dimensional $t{-}J$ model by using an improved variational method based on a wave function that contains both the antiferromagnetic and the d-wave superconducting order parameters. In particular, we generalize the wave function introduced some time ago by J.P. Bouchaud, A. Georges, and C. Lhuillier [J. de Physique {\bf 49}, 553 (1988)] by considering also a {\it long-range} spin-spin Jastrow factor, in order to correctly reproduce the small-$q$ behavior of the spin fluctuations. We mainly focus our attention on the physically relevant region $J/t \sim 0.4$ and find that, contrary to previous variational ansatz, this state is stable against phase separation for small hole doping. Moreover, by performing projection Monte Carlo methods based on the so-called fixed-node approach, we obtain a clear evidence that the $t{-}J$ model does not phase separate for $J/t \lesssim 0.7$ and that the compressibility remains finite close to the antiferromagnetic insulating state.

description: A study on the photosphere and disc of the Be star $β$ Psc is presented. We recover almost 40 years of high-resolution spectroscopic observations and additional data gathered from the BeSS database. We evaluate the photospheric parameters from the SED and fittings of state-of-the-art non-LTE model atmospheres to observed helium, carbon, silicon and magnesium line profiles. Our models include the stellar geometric deformation as well as the co-latitude dependence of temperature and gravity, aiming to derive the effects of rotation on the stellar parameters. We estimate the circumstellar disc parameters from the fitting of models assuming different disc properties, namely its radius and gas density profile. The disc inclination angle $i$ is constrained from the fittings of He I 4471 Å, Mg II 4481 Å, C II 4267 Å, and Si II 4128, 4132 Å lines with gravity darkened models. Our findings, based on model fittings, suggest that during the last 40 years the disc radius changed within the interval $5.5 \le R_d \le 7.8$ $R_*$, the disc base gas density within $5 \times 10^{-13} \le ρ\le 1 \times 10^{-12} g cm^{-3}$, while the radial power-law density index $m$ assumed values between 2.0 and 2.3. These results are in agreement with recent works dealing with spectroscopic and interferometric measurements of this object.

description: Introduction: The prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) colonization among emergency medicine services (EMS) personnel is not well studied. MRSA colonization can be a health hazard for personnel and patients. Research question: I hypothesized that the prevalence of MRSA colonization among EMS Personnel is higher than among the general population. Methodology: MRSA colonization among EMS personnel selected from two different jurisdictions in the USA was investigated. Nasal swabbing was performed and inoculated onto a special agar medium (C-MRSAgar). Polymerase chain reaction test was performed. Findings: Samples and data were collected from 110 volunteers. Among the subjects seven samples were positive for MRSA (6.4% P ?? 0.0003; 95% CI [0.018, 0.110]). The prevalence of MRSA colonization among the general population is 1.5%. Conclusion: There is evidence that EMS personnel have a higher prevalence of MRSA colonization than the general population. This can be a risk to patients and an occupational hazard.

description: This research attempts to understand the perspectives of two Cameroonian women living in the U.S. The research focuses on the roles, expectations, and stereotypes of Cameroonian and American women and men. After interviewing, transcribing, and interpreting the data, this ethnographic study concludes that although gender roles, expectations, and stereotypes are different among Cameroonians and Americans, other themes are important. Those other themes are family and opportunities. Finally, the women in this study are not typical Cameroonian women because they're in the U.S. studying, childless, single, and putting their careers before establishing a nuclear family.

description: We report the final results of our study of the cosmic microwave background (CMB) with the BIMA array. Over 1000 hours of observation were dedicated to this project exploring CMB anisotropy on scales between 1' and 2' in eighteen 6.6' FWHM fields. In the analysis of the CMB power spectrum, the visibility data is divided into two bins corresponding to different angular scales. Modeling the observed excess power as a flat band of average multipole ell= 5237, we find Delta T_1^2=220_{-120}^{+140} muK^2 at 68% confidence and Delta T_1^2 >0 muK^2 with 94.7% confidence. In a second band with average multipole of ell = 8748, we find Delta T_2^2 consistent with zero, and an upper limit 880 muK^2 at 95% confidence. An extensive series of tests and supplemental observations with the VLA provide strong evidence against systematic errors or radio point sources being the source of the observed excess power. The dominant source of anisotropy on these scales is expected to arise from the Sunyaev-Zel'dovich (SZ) effect in a population of distant galaxy clusters. If the excess power is due to the SZ effect, we can place constraints on the normalization of the matter power spectrum sigma_8 = 1.03^{+0.20}_{-0.29} at 68% confidence. The distribution of pixel fluxes in the BIMA images are found to be consistent with simulated observations of the expected SZ background and rule out instrumental noise or radio sources as the source of the observed excess power with similar confidence to the detection of excess power. Follow-up optical observations to search for galaxy over-densities anti-correlated with flux in the BIMA images, as might be expected from the SZ effect, proved to be inconclusive.

description: A Full Plate marks the culmination of three years of actions in Southwest Baltimore. Through my work, I seek to generate a critical dialogue about food justice, which is defined as a community's right to access healthy food.  The installation in the CADVC is a three-walled grid comprised of 317 ceramic dinner plates painted by attendees of workshops focused on personal food histories and our role in food systems. My artistic practice, which is defined by direct engagement with community groups and an emphasis on dialogical forms, has a long legacy within the history of art. The form itself is defined by flexibility in process and in semantics; both the creative practices and the vocabulary we use to define and critique them are changing constantly. This paper analyzes socially engaged artist projects, and describes my own artistic practice, positioning it within the contemporary sphere of socially engaged art.

Description (Gorochov. 1988). The size is large. The coloring is light. The head is rather wide, with poorly developed ocellar tubercles, as others pecies; coloration of the head is fawn with a brownish transverse spot between the eyes (above the median ocellus). The pronotum is also pale yellow, but with a brown pattern on the disc. Elytra, legs, abdomen almost uniform, fawn. The hindwings protrude considerably posteriorly from under the tegmina; their tops are yellowish. The forelegs are relatively weakly pubescent. It differs from the nominative species in larger size, wider head in the male, less pubescent fore tibiae and a somewhat different shape of the apex of the middle posterior protrusion of the epiphallus. It differs from other species of the genus in its generally lighter color and a small spermatophore sac in the male genitalia, which, like in other species, does not significantly reach the tops of the ramuses in front.

description: During development, topography is cut, filled, and graded, altering natural surface drainage patterns. The spatiotemporal characteristics of drainage network and hillslope changes throughout the development process are to date unknown. For this study we used multiple temporal LiDAR-derived DEMs spanning the development of two small agricultural watersheds to examine geomorphic changes caused by urban development. A third forested watershed was also examined to track geomorphic changes not attributable to development. We first present a technique to extract drainage channel heads and drainage networks through time utilizing surface tangential curvature and compare its ability to predict field verified channel heads against two other delineation techniques. Second, subwatersheds of the delineated networks were used to summarize topographic changes in the forested and developing watersheds through time. Finally, simplified hydrologic response functions are generated for each time step utilizing width functions augmented by the curvature delineated networks. Landscape dissection and hydrologicconnectivity increased throughout development, indicating an increased efficiency of water removal from the landscape. Substantial topographic changes manifest as variations in curvature standard deviations through time in first order catchments, highlighting redistribution of high and low gradient regions. Idealized hydrologic responses reflect increased landscape connectivity with a distinct shift toward more rapid storm response shapes throughout the development process. Unexpectedly high temporal variance observed in the forested watershed across analyses indicates inherent differences in temporal digital topographic datasets. Results of this thesis highlight fundamental geomorphic changes caused by development practices while developing methods and rationale for temporal DEM-based geomorphic studies.

description: Приоритетной задачей научных исследований является совершенствование системы оценки качества винодельческой продукции. Фруктовые вина из ягодного сырья пользуются большой популярностью за счет значительного содержания антоцианов, обладающих высокой биологической активностью. Цель работы - разработка способа определения качества и выявления фальсифицированной продукции на основе исследования состава антоцианов вин из малины и черной смородины. В качестве объектов исследований были использованы образцы вин из малины и черной смородины, приобретенные в торговых сетях Москвы. Показано, что количественное содержание групп фенольных соединений не дает исчерпывающей информации о качестве и происхождении фруктового вина. Для определения качественного состава и количественного соотношения антоцианов в образцах вин применяли метод ВЭЖХ-МС. Для этих целей были разработаны специальные режимы разделения на приборе UltiMate 3000 (Thermo Scientific, США). Показано, что содержание и состав фенольных соединений и отдельных антоцианов в винах в основном определяются видом сырья и могут незначительно меняться в зависимости от особенностей технологии и длительности хранения готовой продукции. Определены характерные показатели антоциановых профилей натуральных сортовых ягодных вин из малины и черной смородины. Установлено, что для подлинных вин из малины характерным является содержание пяти основных цианидинов: цианидин-3-софорозида (22-24 %), цианидин-3-самбубиозида (20-23 %), цианидин-3-глюкозида (17-22 %), цианидин-3-глюкозилрутинозида (10-14 %) и цианидин-3-рутинозида (8-10 %). Для высококачественных вин из черной смородины характерным являются содержание суммы дельфинидин-3-рутинозида и дельфинидин-3-глюкозида в пределах 53±5 % и содержание цианидин-3-глюкозида 28-35 %. Способ идентификации вин из малины и черной смородины на основе исследования качественного состава мономерных антоцианов, использованный в данной работе, продемонстрировал достаточно высокую эффективность при оценке качества и выявлении фальсифицированной продукции.

description: Platform heterogeneity, propagation delays, and link disruptions limit the scalability of sensing internetworking architectures. I present a challenged sensor internetwork (CSI) architecture that federates networks behind an overlay abstracted from individual data link layers. The associated delay-tolerant algorithms described in this work allow message exchange over otherwise incompatible networking stacks and enable novel concepts such as the NASA Solar System Internet (SSI).  Border monitoring, undersea surveillance, and the SSI exemplify the need for spatially scaling networks. Existing deployments poorly address different physical links and frequent delays/disruptions. Virtual circuits abstracted from differences in the physical, data-link, and transport layers represent a unique solution to the problems of scaling diverse networks.  I describe the CSI architecture as the intersection of wireless, delay-tolerant, and heterogeneous networks and describe special characteristics of this architecture that enable useful assumptions to optimize messaging. I define an InterNetwork Routing (INR) framework that decomposes the routing function into discrete logical steps and I provide algorithms for each of these steps. An inferred Contact Graph Routing (iCGR) algorithm populates logical graphs from local nodes. A Contact Graph Routing with Extension Blocks (CGR-EB) algorithm provides a hybrid source-path algorithm for synchronizing link state along network paths. A Predictive Capacity Consumption (PCC) algorithm exploits CGR-EB data to build a congestion model. Payload Aggregation/Fragmentation (PAF) and Traffic-Shaping Contacts (TSC) algorithms condition data and place limits on the amount of internetwork traffic carried over local networks.  High fidelity simulations demonstrate performance in a variety of scenarios. iCGR performs within ~15% of a perfect-knowledge system. CGR-EB has a speedup over standard approaches by 300% in stable topologies, by 3000% in unstable topologies, and by 11000% in unstable topologies with non-monotonic cost functions. PCC delivers 97% more data in congested networks over table-based approaches and 37% more data than the INR framework without the congestion model. PAF/TSC reduces message count by 43% while increasing goodput by 63%.  This work enables spatially distributed, scalable internetworks managed behind a consolidated data and control plane. The principals of network semi-structure and path locality should be considered in any new sensor internetwork deployment, and particularly when considering graph-based networking at astronomical scales.

description: Peer reviewing is a central process in modern research and essential for ensuring high quality and reliability of published work. At the same time, it is a time-consuming process and increasing interest in emerging fields often results in a high review workload, especially for senior researchers in this area. How to cope with this problem is an open question and it is vividly discussed across all major conferences. In this work, we propose an Argument Mining based approach for the assistance of editors, meta-reviewers, and reviewers. We demonstrate that the decision process in the field of scientific publications is driven by arguments and automatic argument identification is helpful in various use-cases. One of our findings is that arguments used in the peer-review process differ from arguments in other domains making the transfer of pre-trained models difficult. Therefore, we provide the community with a new peer-review dataset from different computer science conferences with annotated arguments. In our extensive empirical evaluation, we show that Argument Mining can be used to efficiently extract the most relevant parts from reviews, which are paramount for the publication decision. The process remains interpretable since the extracted arguments can be highlighted in a review without detaching them from their context.

description: На проявление генетического потенциала животных оказывает определяющее влияние полноценность кормления. Одним из путей повышения производства свинины и улучшения ее качества является направленное изучение и внедрение новых технологий выращивания, содержания и кормления как отдельными звеньями, так и комплексным подходом по всей биотехнологической цепи. Благодаря этому можно повысить производительность и рентабельность производства. В статье приведены данные по исследованию качественных характеристик свинины, полученной от животных, употреблявших новую кормовую добавку комплексного действия. В результате контрольного убоя подопытных свиней с массой 100 кг было выявлено, что использование антистрессовых препаратов в определенной степени влияло на их убойные и мясные качества. В тушах отмечено увеличение содержания мышечной и снижение жировой ткани, и это несмотря на то, что живая масса свиней в опытных группах была выше, чем в контрольной. У молодняка свиней, получавших добавки Лактумин и Тодикамп-Лакт, был выше белково-качественный показатель мяса, причем наиболее значительно этот показатель возрастал у животных III, IV, V и VI групп - на 0,05, 0,07, 0,09 и 0,16 ед. При этом отмечено влияние антистрессовых препаратов на качественные показатели, в частности, увеличивалось содержание мышечной ткани, и снижалась толщина мышечных волокон. Наиболее высокое значение этих показателей отмечено у свиней III, IV, V и VI групп, то есть получавших Лактумин и Тодикамп-Лакт за 7 и 9 дней до убоя при живой массе 100 кг.

description: Η εφοδιαστική αλυσίδα αποτελεί κρίσιμο κομμάτι για την οικονομία και την ομαλή μετακίνηση σημαντικών αγαθών. Λόγω της πανδημίας Covid-19, έγινε αντιληπτό κατά πόσο μια εφοδιαστική αλυσίδα πρέπει να είναι αξιόπιστη, να λειτουργεί σωστά και να βρίσκεται σε κοινή πορεία με τις τεχνολογικές εξελίξεις ώστε να προσαρμόζεται σε κάθε κρίσιμη στιγμή. Στην παρούσα διπλωματική εργασία γίνεται μια βιβλιογραφική έρευνα για τις συνέπειες των υγειονομικών κρίσεων, και ιδιαίτερα της πανδημίας Covid-19, στην παγκόσμια εφοδιαστική αλυσίδα, με ιδιαίτερη έμφαση στις μεταφορές. Η ραγδαία εξάπλωση της πανδημίας έφερε τεράστιες αλλαγές στις οργανωτικές δομές της εφοδιαστικής αλυσίδας και θέτει τα θεμέλια για το πως θα λειτουργεί ο κλάδος των Logistics στο μέλλον. Επίσης, γίνεται μια αναφορά πάνω στη θεωρία για το τι είναι η εφοδιαστική αλυσίδα και πως αλληλεπιδρά με την κοινωνία γενικότερα. Αναφέρονται επίσης στοιχεία για το πως επηρεάστηκαν οι εμπορευματικές μεταφορές, πως εξελίχθηκε η εφοδιαστική αλυσίδα τροφίμων και το ηλεκτρονικό εμπόριο και γίνεται μια μικρή αναφορά για το πως επηρεάστηκε ο κλάδος των Logistics στην Ελλάδα.
title: A mass conserving mixed stress-strain rate Finite Element Method for Non-Newtonian fluid simulations

description: Many non-Newtonian models assume a non-linear relation between the deviatoric stress tensor τ and the rate-of-strain tensor ε(u), which is not necessarily given in explicit form. Therefore the requirement on a finite element method is the capability to capture the behaviour of the non-linear constitutive relation.Inspired by the work of [GLS19, GLS20] and assuming incompressible, stationary, is other- mal, laminar flow, we present a new mixed finite element method by introducing a variable for the rate-of-strain tensor ε, such that the embedding of a general implicit constitutive relation of the form G(τ,ε) := 0 is very natural. Thus making it suitable for the simula- tion of a broader range of non-Newtonian fluids.We prove solvability of the new discrete variational formulation in a two-dimensional Newtonian setting by showing continuity of the bilinear forms, coercivity on the kernel and the discrete Ladyzhenskaya–Babuska–Brezzi condition. By construction our newly introduced mixed finite element approximates the velocity u in an exactly divergence free matter. This fact results in a property known as pressure robustness.Ultimately, we perform some non-Newtonian numerical experiments in a two-dimensional channel and illustrate the achieved L2-errors in comparison to various other standard mixed finite elements.

description: Расширяющиеся масштабы международной торговли, ужесточение конкурентной борьбы за рынки сбыта, возрастающие запросы потребителей повышают приоритет вопросов качества и хранимоспособности пищевых продуктов. Кондитерские изделия по химическому составу относятся к многокомпонентным системам, в состав которых входят липиды, азотистые соединения, углеводы, витамины, минеральные вещества, ферменты и др. При хранении каждая из перечисленных составляющих подвергается сложным преобразованиям, которые могут привести к снижению потребительских характеристик, пищевой ценности, а также к количественным потерям за счет уменьшения влажности и выделения летучих соединений. Для определения хранимоспособности при выборе методов тестирования и установления критических пределов, необходимых для снижения погрешности оценки, важно использовать научный подход. Хранимоспособность продуктов определяют с помощью научно обоснованных тестов, но вместе с тем наблюдаемые изменения должны всегда увязываться с потребительскими ожиданиями. Перед производителем стоит сложная задача - преобразование «потребительского ожидания» в точно измеряемые научные параметры, поэтому необходимо знать все показатели качества, которые меняются в ходе хранения продукта. В статье рассмотрены теоретические и практические вопросы обеспечения качества и безопасности кондитерских изделий в процессе хранения, от решения которых в значительной степени зависят и экономический уровень развития государства, и здоровье нации. В помощь предприятиям - производителям кондитерских изделий - в статью включены советы и рекомендации, основанные на многолетнем опыте ВНИИКП и направленные на снижение выпуска несоответствующей продукции и увеличение доверия потребителей к выпускаемой продукции.

description: The purpose of the present experiment was to investigate the effects of cervical muscular fatigue on postural control during quiet standing under different conditions of reliability and/or availability of somatosensory inputs from the plantar soles and the ankles and visual information. To this aim, 14 young healthy adults were asked to sway as little as possible in three sensory conditions (No vision, No vision-Foam support and Vision) executed in two conditions of No fatigue and Fatigue of the scapula elevator muscles. Centre of foot pressure (CoP) displacements were recorded using a force platform. Results showed that (1) the cervical muscular fatigue yielded increased CoP displacements in the absence of vision, (2) this effect was more accentuated when somatosensation was degraded by standing on a foam surface and (3) the availability of vision allowed the individuals to suppress this destabilising effect. On the whole, these findings not only stress the importance of intact cervical neuromuscular function on postural control during quiet standing, but also suggest a reweigthing of sensory cues in balance control following cervical muscular fatigue by increasing the reliance on the somatosensory inputs from the plantar soles and the ankles and visual information.

description: [ABRIDGED] The weak gravitational lensing effect is used to infer matter density fluctuations within the field-of-view of the Garching-Bonn Deep Survey (GaBoDS). This information is employed for a statistical comparison of the galaxy distribution to the total matter distribution. The result of this comparison is expressed by means of the linear bias factor, b, the ratio of density fluctuations, and the correlation factor $r$ between density fluctuations. The total galaxy sample is divided into three sub-samples using R-band magnitudes and the weak lensing analysis is applied separately for each sub-sample. Together with the photometric redshifts from the related COMBO-17 survey we estimate the typical mean redshifts of these samples with $\bar{z}=0.35, 0.47, 0.61$, respectively. For all three samples, a slight galaxy anti-bias, b~0.8+-0.1, on scales of a few Mpc/h is found; the bias factor shows evidence for a slight scale-dependence. The correlation between galaxy and (dark) matter distribution is high, r~0.6+-0.2, indicating a non-linear or/and stochastic biasing relation between matter and galaxies. Between the three samples no significant evolution with redshift is found.

How performing a mental arithmetic task modify the regulation of centre of foot pressure displacements during bipedal quiet standing

description: We investigated the effect of performing a mental arithmetic task with two levels of difficulty on the regulation of centre of foot pressure (COP) displacements during bipedal quiet standing in young healthy individuals. There was also a control condition in which no concurrent task was required. A space-time-domain analysis showed decreased COP displacements, along the antero-posterior axis, when participants concurrently performed the most difficult mental arithmetic task. Frequency-domain and stabilogram-diffusion analyses further suggested these decreased COP displacements to be associated with an increased stiffness and a reduction of the exploratory behaviours in the short term, respectively.

description: Without understanding changes in aggregate and compositional properties, it is possible to misinterpret mechanisms driving community variability.  Changes in patterns of variability can be caused by independent and interactive effects of biotic and abiotic drivers.  In an experimental study, I manipulated the presence of a dominant detritivore (P.gentilis) and disturbance (drying).  I found that disturbance lowered aggregate variability and the presence of P.gentilis lowered compositional variability, but only in the absence of disturbance.  In an observational study, I created an index describing relative likelihood of disturbance (system-level drought) for multiple watersheds and tested the impacts of the likelihood of disturbance and the presence of P.gentilis on aggregate and compositional variability.  Disturbance tended to increase aggregate variability and decrease compositional variability, but only in the absence of P.gentilis.  The results of both studies indicate that there may be an interaction between biotic and abiotic drivers that can significantly change community dynamics.
