description: We present updates to \textsc{prism}, a photometric transit-starspot model, and \textsc{gemc}, a hybrid optimisation code combining MCMC and a genetic algorithm. We then present high-precision photometry of four transits in the WASP-6 planetary system, two of which contain a starspot anomaly. All four transits were modelled using \textsc{prism} and \textsc{gemc}, and the physical properties of the system calculated. We find the mass and radius of the host star to be $0.836\pm 0.063\,{\rm M}_\odot$ and $0.864\pm0.024\,{\rm R}_\odot$, respectively. For the planet we find a mass of $0.485\pm 0.027\,{\rm M}_{\rm Jup}$, a radius of $1.230\pm0.035\,{\rm R}_{\rm Jup}$ and a density of $0.244\pm0.014\,ρ_{\rm Jup}$. These values are consistent with those found in the literature. In the likely hypothesis that the two spot anomalies are caused by the same starspot or starspot complex, we measure the stars rotation period and velocity to be $23.80 \pm 0.15$\,d and $1.78 \pm 0.20$\,km\,s$^{-1}$, respectively, at a co-latitude of 75.8$^\circ$. We find that the sky-projected angle between the stellar spin axis and the planetary orbital axis is $λ= 7.2^{\circ} \pm 3.7^{\circ}$, indicating axial alignment. Our results are consistent with and more precise than published spectroscopic measurements of the Rossiter-McLaughlin effect. These results suggest that WASP-6\,b formed at a much greater distance from its host star and suffered orbital decay through tidal interactions with the protoplanetary disc.

description: Monte Carlo simulation is widely used to numerically solve stochastic differential equations. Although the method is flexible and easy to implement, it may be slow to converge. Moreover, an inaccurate solution will result when using large time steps. The Seven League scheme, a deep learning-based numerical method, has been proposed to address these issues. This paper generalizes the scheme regarding parallel computing, particularly on Graphics Processing Units (GPUs), improving the computational speed.

description: On the occasion of its 25th anniversary, we revise Chen's derivative rule for electron tunneling [C.J. Chen, Phys. Rev. B 42, 8841 (1990)] for the purpose of computationally efficient simulations of scanning tunneling microscopy (STM) based on first principles electronic structure data. The revised model allows the weighting of tunneling matrix elements of different tip orbital characters by an arbitrary energy independent choice or based on energy dependent weighting coefficients obtained by an expansion of the tip single electron wavefunctions/density of states projected onto the tip apex atom. Tip-orbital interference in the STM junction is included in the model by construction and can be analyzed quantitatively. As a further advantage, arbitrary tip geometrical orientations are included in the revised model by rotating the coordinate system of the tip apex using Euler angles and redefining the weighting coefficients of the tunneling matrix elements. We demonstrate the reliability of the model by applying it to two functionalized surfaces of recent interest where quantum interference effects play an important role in the STM imaging process: N-doped graphene and a magnetic Mn2H complex on the Ag(111) surface. We find that the proposed tunneling model is 25 times faster than the Bardeen method concerning computational time, while maintaining good agreement. Our results show that the electronic structure of the tip has a considerable effect on STM images, and the Tersoff-Hamann model does not always provide sufficient results in view of quantum interference effects. For both studied surfaces we highlight the importance of interference between s and pz tip orbitals that can cause a significant contrast change in the STM images.

description: Kidney disease may be linked to a decline in cognitive activity. We examined the association of microalbuminuria and cognitive function in a general population of older adults in the United States drawn from the National Health and Nutrition Examination Survey of 1999-2002. Cognitive function was measured by digit symbol substitution in 2,386 participants 60 years of age and older of whom 448 had microalbuminuria. Covariates included age, gender, race/ethnicity, education, smoking, diabetes, and hypertension. Among participants with peripheral artery disease, those with microalbuminuria had a significantly lower cognitive function score compared to those with a normal albumin-to-creatinine ratio. The association between microalbuminuria and cognitive function was weak in those without peripheral artery disease. But in those with peripheral artery disease, the odds of microalbuminuria associated with cognitive function in the lowest and middle tertiles was 6.5 and 3.5, respectively.

description: Pathological classifications in current use for the assessment of glomerular disease have been typically opinion-based and built on the expert assumptions of renal pathologists about lesions historically thought to be relevant to prognosis. Here we develop a unique approach for the pathological classification of a glomerular disease, IgA nephropathy, in which renal pathologists first undertook extensive iterative work to define pathologic variables with acceptable inter-observer reproducibility. Where groups of such features closely correlated, variables were further selected on the basis of least susceptibility to sampling error and ease of scoring in routine practice. This process identified six pathologic variables that could then be used to interrogate prognostic significance independent of the clinical data in IgA nephropathy (described in the accompanying article). These variables were (1) mesangial cellularity score; percentage of glomeruli showing (2) segmental sclerosis, (3) endocapillary hypercellularity, or (4) cellular/ fibrocellular crescents; (5) percentage of interstitial fibrosis/ tubular atrophy; and finally (6) arteriosclerosis score. Results for interobserver reproducibility of individual pathological features are likely applicable to other glomerulonephritides, but it is not known if the correlations between variables depend on the specific type of glomerular pathobiology. Variables identified in this study withstood rigorous pathology review and statistical testing and we recommend that they become a necessary part of pathology reports for IgA nephropathy. Our methodology, translating a strong evidence-based dataset into a working format, is a model for developing classifications of other types of renal disease.

description: Obstructive Sleep Apnea Syndrome (OSAS) is the most common sleep-related breathing disorder. It is caused by an increased upper airway resistance during sleep, which determines episodes of partial or complete interruption of airflow. The detection and treatment of OSAS is particularly important in stroke patients, because the presence of severe OSAS is associated with higher mortality, worse neurological deficits, worse functional outcome after rehabilitation, and a higher likelihood of uncontrolled hypertension. The gold standard test for diagnosing OSAS is polysomnography (PSG). Unfortunately, performing a PSG in an electrically hostile environment, like a stroke unit, on neurologically impaired patients is a difficult task; also, the number of strokes per day outnumbers the availability of polysomnographs and dedicated healthcare professionals. Thus, a simple and automated recognition system to identify OSAS among acute stroke patients, relying on routinely recorded vital signs, is desirable. The majority of the work done so far focuses on data recorded in ideal conditions and highly selected patients, and thus it is hardly exploitable in real-life settings, where it would be of actual use. In this paper, we propose a convolutional deep learning architecture able to reduce the temporal resolution of raw waveform data, like physiological signals, extracting key features that can be used for further processing. We exploit models based on such an architecture to detect OSAS events in stroke unit recordings obtained from the monitoring of unselected patients. Unlike existing approaches, annotations are performed at one-second granularity, allowing physicians to better interpret the model outcome. Results are considered to be satisfactory by the domain experts. Moreover, based on a widely-used benchmark, we show that the proposed approach outperforms current state-of-the-art solutions.

description: Mineral nanoparticle suspensions with consolidating properties have been successfully applied in the restoration of weathered architectural surfaces. However, the design of these consolidants is usually stone-specific and based on trial and error, which prevents their robust operation for a wide range of highly heterogeneous monumental stone materials. In this work, we develop a facile and versatile method to systematically study the consolidating mechanisms in action using a surface forces apparatus (SFA) with real-time force sensing and an X-ray surface forces apparatus (X-SFA). We directly assess the mechanical tensile strength of nanosilica-treated single mineral contacts and show a sharp increase in their cohesion. The smallest used nanoparticles provide an order of magnitude stronger contacts. We further resolve the microstructures and forces acting during evaporation-driven, capillary-force-induced nanoparticle aggregation processes, highlighting the importance of the interactions between the nanoparticles and the confining mineral walls. Our novel SFA-based approach offers insight into nano- and microscale mechanisms of consolidating silica treatments, and it can aid the design of nanomaterials used in stone consolidation.

description: The risk of venous thromboembolic events is thought to be highest in patients with membranous nephropathy. This association has been recently questioned, and it is not known whether this simply reflects the severity of proteinuria. To better understand the relationship between histologic diagnosis and the risk of venous thromboembolic events we evaluated patients in the Toronto Glomerulonephritis Registry. Of 1313 patients with idiopathic glomerulonephritis, 395 were diagnosed with membranous nephropathy, 370 with focal segmental glomerulosclerosis (FSGS), and 548 with immunoglobulin-A nephropathy (IgAN). Risk factors were evaluated by Cox proportional hazards for 53 image-confirmed venous thromboembolic events in 44 patients during a median follow-up of 63 months. The risk was highest in patients with membranous nephropathy and FSGS (hazard ratios of 22 and 7.8, respectively) referenced to patients with IgAN. Following adjustment for gender, cancer history, proteinuria, and serum albumin by multivariable analysis, the histologic subtype remained an independent risk for venous thromboembolic events. This risk was still highest in patients with membranous nephropathy followed by FSGS with adjusted hazard ratios of 10.8 and 5.9, respectively. Thus, in this large cohort, histologic diagnosis was an independent risk factor for venous thromboembolic events. Further studies are needed to discover mechanisms responsible for this high risk in patients with membranous nephropathy.

description: The statistics of extrasolar planetary systems indicate that the default mode of planet formation generates planets with orbital periods shorter than 100 days, and masses substantially exceeding that of the Earth. When viewed in this context, the Solar System is unusual. Here, we present simulations which show that a popular formation scenario for Jupiter and Saturn, in which Jupiter migrates inward from a > 5 AU to a ~ 1.5 AU before reversing direction, can explain the low overall mass of the Solar System's terrestrial planets, as well as the absence of planets with a < 0.4 AU. Jupiter's inward migration entrained s ~ 10-100 km planetesimals into low-order mean-motion resonances, shepherding and exciting their orbits. The resulting collisional cascade generated a planetesimal disk that, evolving under gas drag, would have driven any pre-existing short-period planets into the Sun. In this scenario, the Solar System's terrestrial planets formed from gas-starved mass-depleted debris that remained after the primary period of dynamical evolution.

description: Rhazya stricta Decaisne (Apocynaceae) and Paris polyphylla Smith (Liliaceae) have been investigated as possible sources of medicinal chemicals. They have been presented as separate projects. Rhazya stricta Decaisne, an indole alkaloid bearing plant has been examined for its pharmacological activity. The chromatographic separation of the crude extract of the plant material led into the isolation of six alkaloids which are examined pharmacologically. The identification of these compounds is done by spectroscopic methods including infrared, mass spectrum, 1H and 13C - nuclear magnetic resonance and chromatographic techniques. These alkaloids were converted to quaternary ammonium compounds and their ganglion blocking potencies are tested. The study has been extended to the pharmacological examination of the quaternary compounds of indole alkaloids of other origins. Significant ganglion blocking and neuromuscular blocking activity has been found in some of the quaternised alkaloids, Introductory mass spectrometric study has been made of the indole alkaloids which had been done to a very limited extent before the present work. Paris polyphylla Smith has been examined for central nervous system activity. Chromatographic techniques have led to the isolation of two saponins showing central nervous system depressant activity. Preliminary characterisation of these saponins has been achieved. Paris polyphylla has also been examined for the Possibility of being a source of diosgenin. Analysis of plant materials from different localities at different stages of its growth and various organs of the plant material has been examined for diosgenin content. The analysis has been carried out by using different chromatographic techniques. Leaves were found to contain high yield of diosgenin. Presence of sucrose in high proportion was also observed in the roots of P. polyphylla.
Finite prime-field characteristic sets for planar configurations

Year: 1982

description: Examples are constructed of planar matroids with finite prime-field characteristic sets (i.e. matroids representable over a finite set of prime fields but over fields of no other characteristic). In particular, for any n >3, a projectively unique integer matrix is constructed with 2lsqblog 2 n rsqb+6 columns which often gives nonsingleton characteristic sets and, when n is prime, has characteristic set { n }. Many finite subsets of primes are shown to be characteristic sets, including {23,59} (the smallest pair found using these methods), all pairs of primes {p, p′:67⩽p , and the seventeen largest five-digit primes. Probabilistic arguments are presented to support the conjecture that prime-field characteristic sets exist of every finite cardinality. For p >3, AG(2, p ) is shown to be a subset of PG(2, q ) only for q=p s . Another general construction technique suggests that when P={p 1 ,…,p k } are the primitive prime divisors of 2 n ±1 ( n sufficiently large), then there is a matroid with O (log n ) points whose characteristic set is P. We remark that although only one finite nonsingleton characteristic set (due to R. Reid) was known prior to this paper, a new technique by J. Kahn has shown that every finite set of primes forms a (non-prime-field) characteristic set.

Restricted canonical correlations

description: Given two random vectors Y (1) and Y (2) the first canonical correlation between them is defined as: sup{ Correlation(α′ Y (1) , β′ Y (2) ) : α ε R p , β ε R q }. However, in many practical situations (e.g. educational testing problems, neural networks), some natural restrictions on the coefficients α and β may arise which should be incorporated in this maximization procedure. The maximum correlation subject to such constraints is referred to as the restricted canonical correlation. This problem is treated here under the nonnegativity restriction on α and β. The analysis is extended to more general form of inequality constraints, and also when the restrictions are present only on some of the coefficients. Restricted versions of some other related measures are also discussed. This includes principal component analysis and different modifications of canonical correlations. Anomalies with higher order correlation are also described. Some properties of restricted canonical correlation, including its bounds, are studied.
Bipartite and tripartite systems and matrices from genetic control research

description: Discovering the organizational principles of genetic expression has recently become an arena of substantial investigative effort and modeling challenges. Laboratory findings of geneticists can be couched in terms of classes of stoichiometric networks that through stability analysis lead to classes of matrix patterns. In particular, targets, blocks, and decoys are variables in genetic systems with relationships that can be described by bipartite and tripartite graphs. Related dynamical systems will exhibit stability if a mixture of qualitative and quantitative criteria is applied. Analyses of the models suggest limits of total induction rates of blocks and decoys relative to other rates.

description: любому, кто интересуется историей нашей страны известно, что русский человек пришел когда-то в Сибирь не ради нефти, газа, золота и других ископаемых. Он пришел за пушниной, которая и в царские времена, и в советские, являлась стратегическим товаром, исправно пополняющим валютой казну государства. Но теперь всё радикально изменилось. России она, как стратегический товар, стала неинтересной, поскольку на фоне поступлений в бюджет от нефти, газа и золота, это сущие слёзы. В нынешнее время охотой занимаются те люди, которым данный процесс приносит наслаждение и азарт. Но зачастую охотник 21 века использует свою добычу и для хозяйственной деятельности. Охотничьи избы в большем случае не пригодны для комфортной жизни промысловика. С каждой поездкой нужно позаботиться о электрообеспечении избы, то есть приходится везти тяжелые аккумуляторные батареи, которых на много не хватает, вследствие чего приходится серьезно экономить энергию, что в свою очередь негативно отражается на жизнедеятельность охотника. Поскольку задачей проектирования является создание системы электроснабжения избы для охотника, где отсутствует линия электропередач, поэтому решением этой проблемы является разработка автономной солнечной фотоэлектрической станции (СФЭС).

The cone spectrum of L relative to K is the set of all real λ for which the linear complementarity problem x ∈ K , y = L ( x ) - λ x ∈ K ∗ , and 〈 x , y 〉 = 0 admits a nonzero solution x . In the setting of a Euclidean Jordan algebra H and the corresponding symmetric cone K , we discuss the finiteness of the cone spectrum for Z -transformations and quadratic representations on H .

description: The recent earthquake in Haiti has focused worldwide attention on the need for improved water purification materials and systems. Numerous individuals, religious charities, non-governmental organizations, and private companies have sent water purifications systems to Haiti in recent months in order to stem the spread of waterborne diseases. This recent tragedy has placed a spotlight on the ongoing problem of inadequate access to safe water in developing countries. The United Nations estimates that 1.1 billion people, or eighteen per cent of the world population, cannot obtain safe water at this time. In developing countries, waterborne diseases such as cholera, dysentery, enteric fever, and hepatitis A are quite common. Endemic diarrheal diseases place individuals, particularly children, at risk of arrested growth, malnutrition, and neurological conditions. The World Health Organization states that 1.6 million individuals, mostly young children, die from diarrheal diseases each year.

description: A very high rate for cyclic electron flow (CEF) around PSI (~180 s-1 or 210 s-1 in minimum medium or in the presence of a carbon source respectively) is measured in the presence of methyl viologen (MV) in intact cells of Chlamydomonas reinhardtii under anaerobic conditions. The observation of an efficient CEF in the presence of methyl viologen is in agreement with the previous results reports of Asada et al in broken chloroplasts (Plant Cell Physiol. 31(4) (1990) 557-564). From the analysis of the P700 and PC absorbance changes, we propose that a confinement between 2 PC molecules, 1 PSI and 1 cytb6f corresponding to a functional supercomplex is responsible for these high rates of CEF. Supercomplex formation is also observed in the absence of methyl viologen, but with lower maximal CEF rate (about 100 s-1) suggesting that this compound facilitates the mediation of electron transfer from PSI acceptors to the stromal side of cytb6f. Further analysis of CEF in mutants of Chlamydomonas defective in state transitions shows the requirement of a kinase-driven transition to state 2 to establish this functional supercomplex configuration. However, a movement of the LHCII antennae is not involved in this process. We discuss the possible involvement of auxiliary proteins, among which is a small cytb6f-associated polypeptide, the PETO protein, which is one of the targets of the STT7 kinase.

description: In certain combustion models, an initial temperature profile will develop into a combustion wave that will travel at a specific wave speed. Other initial profiles do not develop into such waves, but die out to the ambient temperature. There exists a clear demarcation between those initial conditions that evolve into combustion waves and those that do not. This is sometimes called a watershed initial condition. In this paper we will show that there may be numerous exact watershed conditions to the initial-Neumann-boundary value problem ut= Duxx+ e-1/u- σ(u-α), with ux(0, t) = ux(1, t) = 0, on = [0, 1]. They are composed from the positive non-constant solutions of Duxx+ e-1/υ- σ(υ-α) = 0, with υx(0) = υx(1) = 0, for small values of D. We will give easily verifiable conditions for when combustion waves arise and when they do not.

description: A crucial issue in the empirical measurement of membership functions is whether the degree of fuzziness is invariant under different scaling procedures. In this paper a direct and an indirect procedure, magnitude estimation and graded pair-comparison, are compared in the context of establishing membership functions for probability phrases such as , and so forth. Analyses at the level of individual respondents indicate that: (a) membership functions are stable over time; (b) functions for each phrase differ substantially over people; (c) the two procedures yield similarly shaped functions for a given person-phrase combination; (d) the functions from the two procedures differ systematically, in that those obtained directly dominate, or indicate greater fuzziness than do those obtained indirectly; and (e) where the two differ the indirectly obtained function may be the more accurate one. A secondary purpose of the paper is to evaluate the effects of the modifiers and . has a general intensifying effect that is described by Zadeh's concentration model for 7 subjects and by a shift model for no one. The effects of are unsystematic and not described by any available model.

description: INTRODUCTION: Markers of hemostasis such as procoagulant factors and peak thrombin generation are associated with cardiovascular outcomes, but their associations with dementia risk are unclear. We aimed to evaluate prospective associations of selected procoagulant factors and peak thrombin generation with dementia risk.
METHODS: We measured levels of 7 hemostatic factors (fibrinogen, factor VII coagulant activity [FVIIc], activated factor VII [FVIIa], factor VIIa-antithrombin [FVIIa-AT], factor XI antigen [FXI], peak thrombin generation, and platelet count) among participants in the Cardiovascular Health Study, a cohort of older adults free of dementia in 1992/1993 (n = 3185). Dementia was adjudicated and classified by DSM-IV criteria through 1998/1999. Cox proportional hazards models estimated hazard ratios (HRs) for any dementia associated with 1-standard deviation (SD) differences, adjusting for sociodemographic and clinical factors and APOE genotype. Secondary analyses separately evaluated the risk of vascular dementia, Alzheimer's disease, and mixed dementia.
RESULTS: At baseline, participants had a median age of 73 years. Over 5.4 years of follow-up, we identified 448 dementia cases. There was no evidence of linear associations between levels of these hemostatic factors with any dementia risk (HRs per 1-SD difference ranged from 1.0 to 1.1; 95 % confidence intervals included 1.0). Results of secondary analyses by dementia subtype were similar.
CONCLUSIONS: In this prospective study, there was no strong evidence of linear associations between levels of fibrinogen, FVIIc, FVIIa, FVIIa-AT, FXI, peak thrombin generation, or platelet count with dementia risk. Despite their associations with cardiovascular disease, higher levels of these biomarkers measured among older adults may not reflect dementia risk.

description: NOVAworks has not been able to increase the long-term career mobility of enough
vulnerable workers in its area of service. We identified two main underlying reasons for this
challenge. Firstly, NOVAworks has faced difficulty in registering vulnerable workers as
customers, due to a lack of awareness of NOVAworks’s programs, a lack of trust in a successful
outcome, and resource barriers to participating in a workforce development program. Secondly,
the workforce development system focuses on unemployment, rather than underemployment and
working poverty, which require different lenses through which to operate.

description: RCW120 is a Galactic HII region having a beautiful ring shape bright in infrared. Our new CO J=1-0 and J=3-2 observations performed with the NANTEN2, Mopra, and ASTE telescopes have revealed that two molecular clouds with a velocity separation of 20km/s are both physically associated with RCW120. The cloud at -8km/s apparently traces the infrared ring, while the other cloud at -28km/s is distributed just outside the opening of the infrared ring, interacting with the HII region as supported by high kinetic temperature of the molecular gas and by the complementary distribution with the ionized gas. A spherically expanding shell driven by the HII region is usually discussed as the origin of the observed ring structure in RCW120. Our observations, however, indicate no evidence of the expanding motion in the velocity space, being inconsistent with the expanding shell model. We here postulate an alternative that, by applying the model introduced by Habe & Ohta (1992), the exciting O star in RCW120 was formed by a collision between the present two clouds at a colliding velocity ~30km/s. In the model, the observed infrared ring can be interpreted as the cavity created in the larger cloud by the collision, whose inner surface is illuminated by the strong UV radiation after the birth of the O star. We discuss that the present cloud-cloud collision scenario explains the observed signatures of RCW120, i.e., its ring morphology, coexistence of the two clouds and their large velocity separation, and absence of the expanding motion.

Distinct domains mediate the early and late functions of the Drosophila ovarian tumor proteins

description: The Drosophila melanogaster ovarian tumor (otu) gene encodes two novel protein isoforms that are required at multiple stages of oogenesis. We have examined the activity of a set of C-terminal truncation Otu proteins as well as a GFP-tagged Otu (Otu-GFP). These experiments have shown that a putative Tudor domain in the central region of the large Otu isoform and a separate domain in the C-terminal region are required for regulation of cyst formation and oocyte maturation, respectively. We also present evidence that a portion of Otu co-fractionates with mRNA/protein complexes (mRNPs) and show that Otu-GFP associates with cytoplasmic aggregates at periphery of the nucleus at an intermediate stage of oogenesis. This study substantially clarifies the relationship between Otu structure and function and reveals new clues about interacting components.

description: Adriano Olivetti and the people who collaborated with him to realize his “possible dream” are recounted by Laura Curino, author and actress of the theatrical works Adriano Olivetti. Il sogno possibile and Camillo Olivetti. Alle radici di un sogno, both directed by Gabriele Vacis.
What emerge from the narration are not only Adriano Olivetti’s ability to delegate and dialogue, his entrepreneurial realism, and the practice of corporate social responsibility often invoked today, but also the many sides of the person we call ‘Adriano’ who actualized the vision of an industry capable of joining profit motives with the welfare of the bodies and minds of its workers. Curino outlines the urgency of reflecting on how technology and Big Data interact and interfere with the concept of ‘person’. Her contribution is accompanied by an intervention by Vacis who, together with Curino, traces the relationship between Laboratorio Teatro Settimo and current interest in Olivetti.
