description: The inconsistency about the degree of geometrical frustration has been a long issue in AV$_{2}$O$_{4}$ (A $\equiv$ Zn, Cd and Mg) compounds, which arises from the two experimental results: (i) frustration indices and (ii) magnetic moments. In the present study, we try to understand such inconsistency by using {\it ab initio} electronic structure calculations. The orbital degrees of freedom are found to play an important role in understanding the geometrically frustrated magnetic behaviour of these compounds. The inclusion of the orbital and spin angular momenta for calculating the frustration indices improves the understanding about the degree of geometrical frustration in these compounds. The calculated values of the frustration indices ($f$$_{\it J}$) are largest for MgV$_{2}$O$_{4}$ and smallest for CdV$_{2}$O$_{4}$ for 3.3$\leq$ $U \leq$5.3 eV. In this range of $U$, the calculated values of $Δ$M$_{2}$=M$_{\rm total}$-M$_{\rm exp}$ are largest for MgV$_{2}$O$_{4}$ and smallest for CdV$_{2}$O$_{4}$. Hence, the consistency about the degree of geometrical frustration is achieved. The absolute values of the nearest neighbour exchange coupling constant ({\it J$_{nn}$}) between V spins are found to be largest for MgV$_{2}$O$_{4}$ and smallest for CdV$_{2}$O$_{4}$, which indicate that the calculated absolute values of the Curie-Weiss temperature ($\varTheta$$_{CW}$)$_{\it J}$ are highest for MgV$_{2}$O$_{4}$ and smallest for CdV$_{2}$O$_{4}$ for 3.3$\leq$ $U \leq$5.3 eV. In this range of $U$, the magnetic transition temperature ($T$$_{N}$)$_{\it J}$ is found to be $\sim$150 K, $\sim$60 K and $\sim$22 K for MgV$_{2}$O$_{4}$, ZnV$_{2}$O$_{4}$ and CdV$_{2}$O$_{4}$, respectively, which shows that the order of ($T$$_{N}$)$_{\it J}$ is similar to that of ($T$$_{N}$)$_{\rm exp}$ for these compounds.

description: We construct a functor from the category of $(\mathbb{Z},X)$-modules of Ranicki (cf. \cite{Ra92}) to the category of homotopy cosheaves of chain complexes of Ranicki-Weiss (cf. \cite{RaWei10}) inducing an equivalence on $L$-theory. The $L$-theory of $(\mathbb{Z},X)$-modules is central in the algebraic formulation of the surgery exact sequence and in the construction of the total surgery obstruction by Ranicki, as described in \cite{Ra79}. The symmetric $L$-theory of homotopy cosheaf complexes is used by Ranicki-Weiss in \cite{RaWei10}, to reprove the topological invariance of rational Pontryagin classes. The work presented here may be considered as an addendum to the latter article and suggests some translation of ideas of Ranicki into the language of homotopy chain complexes of cosheaves.

title: Tackling the 'difficult' subject: An ethnographic exploration of sexual learning in secondary schools
Creators: name: Haste, Polly
Publisher: name: Goldsmiths, University of London
Year: 2009

description: This thesis examines the different ways in which staff in secondary schools engage pupils around issues of sex, sexuality and relationships. Using material from a one- year ethnographic study in an area of London, it addresses the question of why sex education is such a 'difficult' practice and how we are to account for the problems and inadequacies of current provision. The study is framed within a policy and political climate that has expanded the opportunities as well as the pressures for schools to address the emotional, health and welfare needs of its pupils. New policy initiatives have meant that teacher-led formal sex education now occurs alongside other forms of learning and support facilitated by non-teaching staff. This thesis draws on contemporary literature on sexuality and schooling to examine the significance of these shifts and to explore the factors that constrain or enable communication about sex in different contexts within the school. The first two chapters outline the theoretical and methodological framework for the study. The following empirical chapters are divided into three sections. Chapters 3 and 4 examine the experiences of teachers alongside those of other members of staff with responsibility for addressing issues of sexuality with pupils. These chapters consider professional roles and expectations related to sex education and the factors that determine how and whether staff are able to achieve their goals. Chapters 5 and 6 focus on pupils' accounts of sex education and pupil behaviour in the classroom. Drawing on insights from psychoanalysis, these chapters explore the adolescent needs that lie behind pupils' accounts of SRE and their resistant behaviour in the classroom. Chapters 7 and 8 move away from the classroom and the teacher/pupil dynamic to focus on some of the alternative ways in which issues of sex and sexuality are addressed in schools. They look at pupils' communication practices in non-traditional school settings and at how pupils use these settings to experiment with different forms of subjectivity. In the concluding chapter I argue that the insights gleamed from these alternative spaces forces us to re-examine some of the key assumptions behind sex education as a 'difficult' practice.

description: The spectral composition of ambient light varies across both space and time. Many species of jawed vertebrates adapt to this variation by tuning the sensitivity of their photoreceptors via the expression of CYP27C1, an enzyme that converts vitamin A1 into vitamin A2, thereby shifting the ratio of vitamin A1-based rhodopsin to red-shifted vitamin A2-based porphyropsin in the eye. Here, we show that the sea lamprey (Petromyzon marinus), a jawless vertebrate that diverged from jawed vertebrates during the Cambrian period (approx. 500 Ma), dynamically shifts its photoreceptor spectral sensitivity via vitamin A1-to-A2 chromophore exchange as it transitions between photically divergent aquatic habitats. We further show that this shift correlates with high-level expression of the lamprey orthologue of CYP27C1, specifically in the retinal pigment epithelium as in jawed vertebrates. Our results suggest that the CYP27C1-mediated vitamin A1-to-A2 switch is an evolutionarily ancient mechanism of sensory plasticity that appeared not long after the origin of vertebrates.

We study these properties in the Erdös--Rényi random graph model G(n,p), proving a sharp threshold for a random graph to have the AS property asymptotically almost surely, and giving fairly tight bounds for the corresponding threshold for CFS. As an application of our results, we show that for any constant p and any $Γ\in G(n,p)$, the right-angled Coxeter group $W_Γ$ asymptotically almost surely has quadratic divergence and thickness of order 1, generalizing and strengthening a result of Behrstock--Hagen--Sisto.

Year: 1989

description: Data from a recently completed case-referent study of childhood cancer were used to explore a possible role of environmental exposures from traffic exhaust. The street addresses of 328 cancer patients and 262 population-based referents were used to assign traffic density (vehicles per day) as a marker of potential exposure to motor vehicle exhaust. An odds ratio of 1.7 [95 % confidence interval (95 % CI) 1.0— 2.8] was found for the total number of childhood cancers and 2.1 (95 % CI 1.1— 4.0) for leukemias in a contrast of high and low traffic density addresses (≥ 500 versus < 500 vehicles per day). Stronger associations were found with a traffic density cutoff score of ~ 10 000
vehicles per day, with imprecise odds ratios of 3.1 (95% CI 1.2-8.0) and 4.7 (95% CI 1.6---13.5) for
the total number of cancers and leukemias, respectively. Adjustment for suspected risk factors for childhood
cancer did not substantially change these results. Though the results are inconclusive, the identified
association warrants further evaluation.

Using a high-accuracy code with unprecedented resolution, shocks, discontinuities, and their intersections are resolved and clarified. Contact discontinuities emanate from triple-shock intersection points, separating fluids of different origins. Shock-diamonds inside the plasmoid appear to decelerate a supersonic flow. New shock-diamonds and a slow expansion fan are found inside the Petschek outflow. A sufficient condition for the new shock-diamonds and the relevance to astrophysical jets are discussed.

description: Objectives Epidemiologic evidence supporting optimal seating is limited and inconsistent. This cross-sectional study was conducted to examine the association between seat inclination, use of lumbar support, and the prevalence of clinically significant low-back pain among taxi drivers.

Methods A digital inclinometer was used to measure inclinations of seat surfaces (θseat) and backrests (θback), and calculate the back-to-thigh angle (θback-thigh). Structured interviews were conducted to gather information on the use of lumbar support and the prevalence of low-back pain that had led to medical attention or absence from driving in the past month. A multiple logistic regression analysis was used to estimate the prevalence odds ratio (OR) with adjustment for age, body mass index, professional seniority, monthly driving hours, and the intensity of exposure to whole-body vibration.

Results Among 224 drivers, the mean θseat and θbackrest were 14.5 (SD 9.6) and 95.1 (SD 2.7) degrees, respectively, resulting in θback-thigh of 80.6 (SD 9.3) degrees. Fifty-five percent used a lumbar support regularly, but 25% reportedly had significant low-back pain. The prevalence of low-back pain was 23% among those with θback-thigh 91 degrees. The adjusted OR comparing those with a θback-thigh of ≤91 degrees to those with a θback-thigh of >91 degrees was 5.11 [95% confidence interval (95% CI) 1.07~24.4]. For regularly using drivers versus those not using lumbar support, the prevalence of low-back pain was 18% versus 34%, with an adjusted OR of 0.33 (95% CI 0.16~0.68). Neither θseat nor θbackrest alone was significantly associated with low-back pain.

Conclusions The epidemiologic observation of this study was consistent with the results of prior biomechanical studies on appropriate seat inclinations and the use of lumbar support. Prospective studies are needed to confirm the true beneficial effects of these seating parameters.

description: G protein-coupled receptors (GPCRs) constitute a large family of receptor proteins that sense molecular signals on the exterior of a cell and activate signal transduction pathways within the cell. Modeling how an agonist activates such a receptor is fundamental for an understanding of a wide variety of physiological processes and it is of tremendous value for pharmacology and drug design. Inelastic electron tunneling spectroscopy (IETS) has been proposed as a model for the mechanism by which olfactory GPCRs are activated by a bound agonist. We apply this hypothesis to GPCRs within the mammalian nervous system using quantum chemical modeling. We found that non-endogenous agonists of the serotonin receptor share a particular IET spectral aspect both amongst each other and with the serotonin molecule: a peak whose intensity scales with the known agonist potencies. We propose an experiential validation of this model by utilizing lysergic acid dimethylamide (DAM-57), an ergot derivative, and its deuterated isotopologues; we also provide theoretical predictions for comparison to experiment. If validated our theory may provide new avenues for guided drug design and elevate methods of in silico potency/activity prediction.

description: For quark matter studies in astrophysics the thermodynamic bag model (tdBAG) has been widely used. Despite its success it fails to account for various phenomena expected from Quantum-Chromo-Dynamics (QCD). We suggest a straightforward extension of tdBAG in order to take the dynamical breaking of chiral symmetry and the influence of vector interactions explicitly into account. As for tdBAG the model mimics confinement in a phenomenological approach. It is based on an analysis of the Nambu--Jona-Lasinio (NJL) model at finite density. Furthermore, we demonstrate how NJL and bag models in this regime follow from the more general and QCD based framework of Dyson-Schwinger (DS) equations in medium by assuming a simple gluon contact interaction. Based on our simple and novel model, we construct quark hadron hybrid equations of state (EoS) and study systematically chiral and deconfinement phase transitions, the appearance of $s$-quarks and the role of vector interaction. We further study these aspects for matter in beta-equilibrium at zero temperature, with particular focus on the current ~2 solar masses maximum mass constraint for neutron stars. Our approach indicates that the currently only theoretical evidence for the hypothesis of stable strange matter is an artifact of tdBAG and results from neglecting the dynamical breaking of chiral symmetry.

description: OBJECTIVES: This study describes the development and evaluation of a method for sampling layers of the stratum corneum for the quantitation of dermal exposure to 1,6-hexamethylene diisocyanate (HDI). METHODS: HDI deposited on skin was collected by the removal of stratum corneum with adhesive tape, derivatized with 1-(2-methoxyphenyl)piperazine, and quantitated as the urea derivative (HDIU) by liquid chromatography-mass spectrometry (LC-MS). This LC-MS method was tested by analyzing tape spiked with HDI-containing products, then applied to tape samples collected from the skin of an auto-body shop worker exposed to polyurethane paint aerosols. RESULTS: The limits of detection and quantitation were 20 and 50 fmol per injection, respectively. The recovery of HDI from the tape was 99.3% [95% confidence interval (95% CI) 97.1-102]. HDIU was stable at -40 degrees C, degrading by 0.28% (95% CI 0.10-0.46) per day. Quantifiable amounts of HDI were observed in 42.6% of the first three successive tape-strip samples collected from 36 different sites on the skin of the worker. The amount of HDI recovered from the collection sites on skin, measured by summing the levels collected with three successive tape-strips, ranged from nondetectable to 1874 pmol.CONCLUSIONS: This study demonstrates that HDI on skin can be collected with tape-strips and quantified at occupational levels using LC-MS.

description: We explore the nature of glass-formation in variable spatial dimensionality ($d$) based on the generalized entropy theory, a synthesis of the Adam-Gibbs model with direct computation of the configurational entropy of polymer fluids using an established statistical mechanical model. We find that structural relaxation in the fluid state asymptotically becomes Arrhenius in the $d\rightarrow\infty$ limit and that the fluid transforms upon sufficient cooling above a critical dimension near $d=8$ into a dense amorphous state with a finite positive residual configurational entropy. Direct computations of the isothermal compressibility and thermal expansion coefficient, taken to be physical measures of packing frustration, demonstrate that these fluid properties strongly correlate with the fragility of glass-formation.

description: We show that properties of hypergeometric type equations become transparent if they are derived from appropriate 2nd order partial differential equations with constant coefficients. In particular, we deduce the symmetries of the hypergeometric and Gegenbauer equation from conformal symmetries of the 4- and 3-dimensional Laplace equation. We also derive the symmetries of the confluent and Hermite equation from the so-called Schrödinger symmetries of the heat equation in 2 and 1 dimension. Finally, we also describe how properties of the ${}_0F_1$ equation follow from the Helmholtz equation in 2 dimensions.

Key types of data include consortium research projects using cross-national surveys, standardized data from international organizations, well-respected databases from individual research teams checked for consistency over time or across areas, metrics data, and one-off datasets deposited by individual researchers or teams in data archives. Yet re-using any data collected by others for new and different purposes can entail compromises. Question wordings in surveys or categories/concepts in official statistics may only partly capture the phenomena in which you are interested. ‘Mashing’ data from different sources or across different units or periods can be tricky. And for individual deposited datasets or constructed metrics, clarifying how the data was originally created and cleaning it so that it can be fully understood can be non-trivial tasks. This session examines how to develop research questions for re-using and mashing data, how to work with the limitations of secondary data sources, and how novel insights can be gained from bringing datasets together. This event was part of a series of seminars organised to support the development of the CIVICA Research Open Science Handbook for the Social Sciences.

GRB 110731A: Early afterglow in stellar wind powered by a magnetized outflow

description: One of the most energetic gamma-ray burst GRB 110731A was observed from optical to GeV energy range. Previous analysis on the prompt phase revealed similarities with the Large Area Telescope (LAT) bursts observed by Fermi: i) a delayed onset of the high-energy emission ($> 100$ MeV), ii) a short-lasting bright peak at later times and iii) a temporally extended component from this phase and lasting hundreds of seconds. Additionally to the prompt phase, multiwavelength observations over different epochs showed that the spectral energy distribution was better fitted by a wind afterglow model. We present a leptonic model based on an early afterglow that evolves in a stellar wind of its progenitor. We apply this model to interpret the temporally extended LAT emission and the brightest LAT peak exhibited by the prompt phase of GRB 110731A. Additionally, using the same set of parameters, we describe the multiwavelength afterglow observations. The origin of the temporally extended LAT, X-ray and optical flux is explained through synchrotron radiation from the forward shock and the brightest LAT peak is described evoking the synchrotron self-Compton emission from the reverse shock. The bulk Lorentz factor required in this model ($Γ\simeq520$) lies in the range of values demanded for most LAT-detected gamma-ray bursts. We show that the strength of the magnetic field in the reverse-shock region is $\sim$ 50 times stronger than in the forward-shock region. This result suggests that for GRB 110731A, the central engine is likely entrained with strong magnetic fields.

title: The organization of action representation and the interaction between the action and perception systems
Creators: name: Simonelli, Francesca

description: Action representation is thought to rely on hierarchical processing, whereby action-related information is represented across different levels of abstraction. The visual processing of human actions is subserved by the Action Observation Network (AON), spanning separate anatomical areas. Rather than relying on a modular organization based on the segregation of action features, the AON organization may be based on distributed representations, overlapping across a wide expanse of the cortex and supporting a high-dimensional representational space. Coherently with modern perspectives of distributed interactive cortical systems, it has been proposed that the same representational systems are shared between action, perception, and higher-level cognitive functions; in this view, action and perception are interdependent systems characterized by reciprocal influences. In the first and second studies, we aimed to better characterize the organization of the AON at different levels of the action hierarchy by measuring brain hemodynamic activity and representational geometries during observation of transitive and intransitive gestures. In the third study, we propose a novel methodological and analytical framework aimed at investigating the interplay between action and perceptual processes during active perception; we tested the validity of the proposed approach by recording participants’ motor and perceptual behavior during a perceptual decision-making task and assessing the influence of motor control features on decision formation. The results of the first and the second study indicate that actions categories are not encoded in a segregated manner and that the same areas of the AON participate in the representations of multiple action features; moreover, the representational content of the AON is not constrained byanatomical proximity, as anatomically distant regions shared similar information content. These findings support the notion that the AON relies on overlapping and distributed coding and may act as a unique representational space. In the third study, we established a link between motor and perceptual behavior, as changes in movement kinematics continuously tracked the decision formation process, and we revealed a significant contribution of grip force to perceptual decisions. These results support the validity of the proposed approach in exploring the relationship between patterns of motor behavior and decision processes and the neurophysiological correlates underlying decision-making mechanisms.

description: We prove existence and uniqueness of solutions to the Minkowski problem in any domain of dependence $D$ in $(2+1)$-dimensional Minkowski space, provided $D$ is contained in the future cone over a point. Namely, it is possible to find a smooth convex Cauchy surface with prescribed curvature function on the image of the Gauss map. This is related to solutions of the Monge-Ampère equation $\det D^2 u(z)=(1/ψ(z))(1-|z|^2)^{-2}$ on the unit disc, with the boundary condition $u|_{\partial\mathbb{D}}=φ$, for $ψ$ a smooth positive function and $φ$ a bounded lower semicontinuous function. We then prove that a domain of dependence $D$ contains a convex Cauchy surface with principal curvatures bounded from below by a positive constant if and only if the corresponding function $φ$ is in the Zygmund class. Moreover in this case the surface of constant curvature $K$ contained in $D$ has bounded principal curvatures, for every $K<0$. In this way we get a full classification of isometric immersions of the hyperbolic plane in Minkowski space with bounded shape operator in terms of Zygmund functions of $\partial \mathbb{D}$. Finally, we prove that every domain of dependence as in the hypothesis of the Minkowski problem is foliated by the surfaces of constant curvature $K$, as $K$ varies in $(-\infty,0)$.

The genomic formation of Tanka people, an isolated "Gypsies in water" in the coastal region of Southeast China
Creators: name: Guanglin He

description: Objectives: Three different hypotheses proposed via the controversial evidence from cultural, anthropological and uniparental genetic analyses respectively stated that Tanka people probably originated from Han Chinese, ancient Baiyue tribe, or the admixture of them. Therefore, the genetic origin and admixture history of the Tanka people, an isolated “Gypsies in water” in the coastal region of Southeast China, are needed to be genetically clarified using genome-wide SNP data. Materials and methods: To elucidate the genetic origin of the Southeast Tanka people and explore their genetic relationship with surrounding indigenous Tai-Kadai (TK), Hmong-Mien (HM) and Austronesian (AN) people and Neolithic-to-historic ancients from the Yellow River Basin (YRB) and Fujian, we conducted a large-scale population genomic study among 1498 modern and ancient Eurasians, in which 73 Tanka and 4 Han people were first reported here. Both allele-shared and haplotype-based statistical methods were used here, including PCA, ADMIXTURE, f-statistics, ALDER, qpGraph-/TreeMix and qpAdm/qpWave, ChromoPainter and fineSTRUCTURE. Results: We found a specific genetic cline in PCA plots and detected the Tanka-specific homogeneous ancestry in model-based ADMIXTURE, suggesting differentiated demographic history between Tanka and surrounding Hans. Formal tests based on sharing allele patterns showed a close relationship between Tanka people and Han Chinese, but the Tanka population harbored more southern indigenous East Asian ancestry related to AA/HM/TK people compared with southern Hans. Besides, the reconstructed differentiated demographic history revealed that southern Xinshizhou Tankas harbored more ancestry related to the TK or coastal ancient Neolithic to Bronze Age southern East Asians compared with northern Shacheng Tankas. The qpGraph-/TreeMix-based phylogenetic framework, qpAdm/qpWave-based admixture modeling and fineSTRUCTURE-based dendrogram among ancient northern and southern East Asians further demonstrated that the primary ancestry of modern Tankas derived from ancient millet farmers in the YRB with additional admixture from multiple southern East Asian sources. Discussion: Sharing ancestry estimated from the f-statistics and sharing haplotypic landscape inferred from the ChromoPainter and fineSTRUCTURE showed that Southeast Tanka people not only had a close genetic relationship with both northern Hans and YRB millet farmers but also possessed more southern East Asian ancestry related to AA/HM/TK speakers. Our genomic data and fitted admixture models supported modern Tanka originated from ancient North China and obtained additional gene flow from ancient southern East Asians in the processes of southward migrations.

description: Using an individual-based model approach we consider trophodynamic effects on the growth and survival of larval cod ( Gadus morhua ) and haddock ( Melanogrammus aeglefinus ) on Georges Bank during late winter/early spring. These studies represent an extension of results described in Werner et al. (1996; Deep-Sea Res. II), wherein the effect of turbulence-enhanced larval-prey contact rates increased the effective prey concentration resulting in growth of cod larvae consistent with observed rates in the field. We reformulated the feeding of the larvae to include existing relationships between maximum prey-length and larval-length and we examined: (i) larval search behaviour and its effect on encounter with prey, (ii) the ability of larvae to pursue and capture prey in a turbulent environment, and (iii) the effect of turbulence on the dispersion of larvae in the vertical. We find that search behaviour, the effect of turbulence on pursuit and capture, and vertical dispersion decrease the predicted larval growth rates compared to those observed in the earlier study. These results suggest that larval feeding behaviour, and especially the ability of larvae to pursue encountered prey, could be an important input to larval growth and survival models. The inclusion of turbulence in determining the position of passive larvae in the water column allows the larvae to sample the entire water column, contributing to a decrease in the variance of the size of the larvae over time. The ability of larvae to swim and aggregate in the vertical will be necessary to reproduce distributions observed in the field.
