description: Magnetization, specific heat, and neutron scattering measurements were performed to study a magnetic transition in jarosite, a spin-5/2 kagome lattice antiferromagnet. When a magnetic field is applied perpendicular to the kagome plane, magnetizations in the ordered state show a sudden increase at a critical field H_c, indicative of the transition from antiferromagnetic to ferromagnetic states. This sudden increase arises as the spins on alternate kagome planes rotate 180 degrees to ferromagnetically align the canted moments along the field direction. The canted moment on a single kagome plane is a result of the Dzyaloshinskii-Moriya interaction. For H < H_c, the weak ferromagnetic interlayer coupling forces the spins to align in such an arrangement that the canted components on any two adjacent layers are equal and opposite, yielding a zero net magnetic moment. For H > H_c, the Zeeman energy overcomes the interlayer coupling causing the spins on the alternate layers to rotate, aligning the canted moments along the field direction. Neutron scattering measurements provide the first direct evidence of this 180-degree spin rotation at the transition.

Investigation of Alexithymia and related psychological factors in relation to body mass index and obesity
Creators: name: Ramzi, Nurul Hanis
Publisher: name: Imperial College London
Year: 2020

description: Common obesity is thought to be the result of genetic variations influencing susceptibility to environmental circumstances related to food intake, mediated by appetite-regulating pathways, and also affected by emotional processing and other behavioural traits. Alexithymia is a psychological construct for emotional processing deficits, characterised by impaired identification and description of feelings, and externally-oriented thinking. Here, I investigate the relationship between alexithymia, measured by the 20-item Toronto Alexithymia scale (TAS-20), and adiposity in two Northern Finland Birth Cohorts (NFBC1966 and NFBC1986) and in severely-obese adults seeking bariatric surgery in the UK (PMMO clinical trial). Analysis of depression as a possible contributing factor in the relationship between alexithymia and obesity was also conducted in the NFBC1966. Consistent associations between BMI and TAS-20 total scores were observed among adult and adolescent general populations and in severely-obese adults (pre- and post-surgery, assessed longitudinally). Males with clinically-relevant alexithymia status (TAS-20≥ 61) and history of depression diagnosis had higher BMI than males without, at age of 31 years in NFBC1966. In the severe obesity clinical trial cohort (PMMO), participants with history of clinical depression diagnosis had higher TAS-20 total scores and weight at baseline than those who had no clinical depression history. Depression and bariatric surgery type were also moderately associated with TAS-20 total scores after surgery. A genome-wide association study was conducted to identify genetic variants influencing psychological measures (TAS-20 and HSCL-13 scores) in the general adult and adolescent populations. In the NFBC1966 dataset, one SNP, rs2242223 (p= 8.10 x 10-8) in the Parkinson’s disease gene SNCAIP (synuclein alpha interacting protein) was associated with TAS-20 score. There were also significant sex and genotype interactions. These findings raise intriguing questions regarding the direction of causal mechanisms between emotional processing and obesity. Design of treatment strategies for complex conditions, such as obesity, would benefit from enhanced understanding of underlying psychological/behavioural components in the general population and clinical patients.

description: Three new bis-azomethine derivatives were synthesized in a good yield, along with their copper(II) complexes and confirmed by IR, 13C-NMR, 1H-NMR, MS, ESR, powder XRD and UV-vis spectroscopy. The spectral studies indicated that the ligands in all complexes act as dibasic tetradentate, coordinated through two azomethine nitrogen and two deprotonated phenolic oxygen atoms. Square planar geometries were assigned for Cu(II) complexes in monomeric structures. Also, quantum chemical calculations using DFT were conducted to elucidate the effect of quantum chemical parameters on the molecular and electronic structures of the molecules under consideration, and then confirming their electrochemical behavior and biological effectiveness. There were good correlations between practical and theoretical studies. The redox pathway of bis-azomethine derivatives and their Cu(II) complexes was elucidated and confirmed based on experimental and theoretical calculations. In vitro antimicrobial effectiveness of the synthesized three ligands and their Cu(II) complexes exhibited varying degrees of inhibitory effect on the growth of the test pathogenic microorganisms, confirming that antimicrobial efficiency is dependent on the molecular structure of the prepared compounds and their liposolubility. The MIC was also determined for the compound H2Lc which exhibited the highest antimicrobial activity against each of Pseudomonas aeruginosa (G-) and Candida albicans.

description: In this paper, we consider a class of gravity whose action represents itself as a sum of the usual Einstein-Hilbert action with cosmological constant and an $U(1)$ gauge field for which the action is given by a power of the Maxwell invariant. We present a class of the rotating black branes with Ricci flat horizon and show that the presented solutions may be interpreted as black brane solutions with two event horizons, extreme black hole and naked singularity provided the parameters of the solutions are chosen suitably. We investigate the properties of the solutions and find that for the special values of the nonlinear parameter, the solutions are not asymptotically anti-deSitter. At last, we obtain the conserved quantities of the rotating black branes and find that the nonlinear source effects on the electric field, the behavior of spacetime, type of singularity and other quantities.

We compare the value of this effect for the vacuum with the one expected for atomic systems. We finally show that ICME could be measured for the first time for noble gases using state-of-the-art laser systems and for the quantum vacuum with near-future laser facilities like ELI and HiPER, providing in particular a test of the nonlinear behaviour of quantum vacuum at intensities below the Schwinger limit of 4.5x10^33 W/m^2.

description: Due to the prevailing pandemic of the coronavirus disease COVID-19, we are experiencing emotional and social isolation, which negatively affects mental and physical health, particularly among the elderly population. In this study, we performed a cross-sectional analysis based on computer-assisted telephone interviews of 500 Polish adults aged 60 years or older in order to determine the impact of the SARS-CoV-2 pandemic on the older population’s behavior, life activity, and delivery of healthcare services. According to our study, COVID-19 infection entailed a substantial change in older people’s behavior. Over 50%, nearly 80%, and more than 25% of the surveyed participants reduced their social, recreational, and professional activities, respectively. The most significant change in senior’s behavior due to the fear of COVID-19 infection was observed in patients (1) with cardiac and pulmonary problems, (2) being on multi-drug therapy, (3) vaccinated against influenza, and (4) with several mental difficulties including loneliness, social isolation, and depression. Furthermore, we demonstrated that 10% of participants canceled planned hospitalization due to the fear of COVID-19 infection. This was observed primarily in patients suffering from chronic heart and lung diseases, vaccinated against influenza, exhibiting the reluctance to carry out more complex daily activities, and with a higher level of anxiety, social loneliness, and malnutrition. Thus, these groups of seniors require more attention; hence, we propose telemedicine as a strategy directed to them that provides clinical healthcare and information regarding measurements, control, and protection against SARS-CoV-2 during the prevailing COVID-19 pandemic. We believe this strategy may improve treatment outcomes, reduce comorbidities-related complications and unnecessary hospitalizations.

description: Three pyrazole derivatives, 3,5-dimethyl-1H-pyrazole (DMPz) (I), 3-methyl-5-phenyl-1H-pyrazole (MPPz) (II), and 3,5-diphenyl-1H-pyrazole (DPPz) (III), were prepared via reacting semicarbazide hydrochloride with the acetylacetone, 1-phenylbutane-1,3-dione, and 1,3-diphenylpropane-1,3-dione, respectively. Complexes 1–3 were isolated by reacting CuCl2·2H2O with I–III, respectively, and characterized by CHNS elemental analyses, FT-IR, UV-Vis, 1H and 13C NMR, EPR spectra, and TGA/DTA. Molecular structures of the pyrazole derivatives I–III and copper(II) complexes 2 and 3 were studied through single-crystal XRD analysis to confirm their molecular structures. Overlapping of hyperfine splitting in the EPR spectra of the dimeric copper(II) complexes 1–3 indicates that both copper centers do not possess the same electronic environment in solution. The copper(II) complexes are dimeric in solid state as well as in solution and catalyze the oxidation of various primary and secondary alcohols selectively. Catalysts 1–3 show more than 92% product selectivity toward ketones during the oxidation of secondary alcohols. Surprisingly primary alcohols, which are relatively difficult to oxidize, produce carboxylic acid as a major product (48%–90% selectivity) irrespective of catalytic systems. The selectivity for carboxylic acid rises with decreasing the carbon chain length of the alcohols. An eco-friendly and affordable catalytic system for oxidation of alcohols is developed by the utilization of H2O2, a green oxidant, and water, a clean and greener solvent, which is a notable aspect of the study.

description: We perform lattice simulations in pure-SU(2) Yang-Mills theory to investigate how the infrared behavior of electric and magnetic gluon propagators in Landau gauge is affected by temperature. We consider the largest lattices to date, in an attempt to keep systematic errors under control. Electric and magnetic screening masses are calculated through an Ansatz from the zero-temperature case, based on complex-conjugate poles for the momentum-space propagators. As recently reported in [1], we find good fits to the proposed form at all temperatures considered, with different ratios of real to imaginary part of the pole masses for the longitudinal (electric) and transverse (magnetic) propagators. The behavior of the magnetic propagator D_T(p) is in agreement with the dimensional-reduction picture, showing infrared suppression (with a turnover in momentum) and violation of spectral positivity at all nonzero temperatures considered. The longitudinal propagator D_L(p) appears to reach a plateau at small momenta and is subject to severe finite-Nt effects around the critical temperature Tc. As a consequence, only lattices with temporal extent Nt > 8 seem to be free from systematic errors. After these errors are removed, the infrared-plateau value is considerably reduced around the transition and the sharp peak observed previously for this quantity at Tc is no longer present. The resulting infrared behavior for D_L(p) at Tc is essentially the same as for 0.5Tc . An investigation of the temperature range between 0.5Tc and Tc reveals that a less pronounced (finite) peak may occur at smaller temperatures, e.g. T ~ 0.9Tc.

description: New optical narrowband imaging observations of the fields of several ULXs are presented. Known supershell nebulae are associated with a number of these ULXs, which we detect in emission line filters such as [S II], He II, [O II] and [O III]. New nebulae are discovered, which are candidate ULX-powered supershells. The morphologies and emission line fluxes of these nebulae could then be used to infer the properties of the emitting gas, which gives clues to the energizing source (photoionization and/or shock-excitation, both possibly from the ULX). Studies of supershells powered by ULXs can help to constrain the nature of ULXs themselves, such as the isotropy of the X-ray emission and the strength of their outflows.

description: The effect of hydrostatic strain and of interstitial hydrogen on the elastic properties of $α$-iron is investigated using \textit{ab initio} density-functional theory calculations. We find that the cubic elastic constants and the polycrystalline elastic moduli to a good approximation decrease linearly with increasing hydrogen concentration. This net strength reduction can be partitioned into a strengthening electronic effect which is overcome by a softening volumetric effect. The calculated hydrogen-dependent elastic constants are used to determine the polycrystalline elastic moduli and anisotropic elastic shear moduli. For the key slip planes in $α$-iron, $[1\bar{1}0]$ and $[11\bar{2}]$, we find a shear modulus reduction of approximately 1.6% per at.% H.

description: N-phenylpyridin-2-ylmethanimine, L, reacts with CoCl2·6H2O to form a water soluble complex, [CoIII(L)2Cl2]Cl, which has been determined by X-ray diffraction analysis. Electrochemical studies show that [CoIII(L)2Cl2]Cl can serve as an electrocatalyst for water or proton reduction to hydrogen from neutral water (pH 7.0) or acetic acid with a turnover frequency (TOF) of 1032.4 and 70.3 moles of hydrogen per mole of catalyst per hour (mol H2/mol catalyst/h) at an overpotential (OP) of 837.6 mV and 941.6 mV, respectively. Compared with the previously described cobalt(II) complex, [CoII(L)2Br2] (TOF: 875.17 mol H2/mol catalyst/h at an OP of 837.6 mV), the cobalt(III) complex, [CoIII(L)2Cl2]Cl exhibits more efficient activity for hydrogen evolution. This can be attributed to CoIII/CoII and CoII/CoI couples of [CoIII(L)2Cl2]Cl are responsible for hydrogen production.

description: Veterinary Herd Health Management plays an important role in veterinary medicine on dairy farms and has also been mandatory at the European Union level since April 21, 2021. Despite the increasing importance of VHHM, little is known about the extent of utilization of VHHM by dairy farmers and their view on this type of collaboration. Therefore, this cross-sectional study aimed to determine the status quo of the currently practiced VHHM in Germany. For this purpose, an online survey was conducted among dairy farmers in November and December 2020. From 216 analyzed questionnaires, about half (n = 106) of the surveyed dairy farmers used VHHM at different scopes. However, regardless of the group, the term “veterinary herd health management” generally was given most relative importance by the participants as a veterinary service for herd fertility improvement, rather than the actual definition of a holistic approach. In contrast to this, the actual motivation of the VHHM participants, to take part in such a program was primarily based on the desire to safeguard animal health by employing preventive measures, that is, to avoid the occurrence of diseases via improved management and to improve farm performance (and profitability). Dairy farmers who opted for VHHM tended to manage larger higher yielding herds than those who did not. Additionally, the farmers in latter farms were more likely to make joint animal health decisions with their veterinarians. Using a latent class analysis, two groups of farmers among farms that were not currently using VHHM were identified, one of which expressed great interest in using VHHM while the other did not. Since the new legal basis makes the topic even more relevant than before, dairy farmers, animals, and veterinarians might benefit from the study to exploit hidden opportunities for VHHM collaboration.

description: Einstein-Hilbert action and its natural generalizations to higher dimensions (like the Lanczos-Lovelock action) have certain peculiar features. All of them can be separated into a bulk and a surface term, with a specific ("holographic") relationship between the two, so that either term can be used to extract information about the other. Further, the surface term leads to entropy of the horizons on-shell. It has been argued in the past that these features are impossible to understand in the conventional approach but find a natural explanation if we consider gravity as an emergent phenomenon. We provide further support for this point of view in this paper. We describe an alternative decomposition of the Einstein-Hilbert action and Lanczos-Lovelock action into a new pair of surface and bulk terms, such that the surface term becomes Wald entropy on a horizon and the bulk term is the energy density (which is the ADM Hamiltonian density for Einstein gravity). We show that this new pair also obeys a holographic relationship and give a thermodynamic interpretation to this relation in this context. Since the bulk and surface terms, in this decomposition, are related to energy and entropy, the holographic condition can be thought of as analogous to inverting the expression for entropy given as a function of energy S = S(E,V) to obtain the energy E = E(S,V) in terms of the entropy in a normal thermodynamic system. Thus the holographic nature of the action allows us to relate the descriptions of the same system in terms of two different thermodynamic potentials. Some further possible generalizations and implications are discussed.

description: Despite rapid advances in experimental cell biology, the in vivo behavior of hematopoietic stem cells (HSC) cannot be directly observed and measured. Previously we modeled feline hematopoiesis using a two-compartment hidden Markov process that had birth and emigration events in the first compartment. Here we perform Bayesian statistical inference on models which contain two additional events in the first compartment in order to determine if HSC fate decisions are linked to cell division or occur independently. Pareto Optimal Model Assessment approach is used to cross check the estimates from Bayesian inference. Our results show that HSC must divide symmetrically (i.e., produce two HSC daughter cells) in order to maintain hematopoiesis. We then demonstrate that the augmented model that adds asymmetric division events provides a better fit to the competitive transplantation data, and we thus provide evidence that HSC fate determination in vivo occurs both in association with cell division and at a separate point in time. Last we show that assuming each cat has a unique set of parameters leads to either a significant decrease or a nonsignificant increase in model fit, suggesting that the kinetic parameters for HSC are not unique attributes of individual animals, but shared within a species.

Publisher: name: University of British Columbia

description: This research investigates the feasibility of developing value-added products from lignin in nanofibre form for structural and functional applications. Specifically, softwood Kraft lignin (SKL) was used as the precursor to fabricate nanofibres via the electrospinning process and then converted into carbon nanofibres (CNF). The mechanical properties of SKL nanofibres were characterized for structural applications at the nanofibre mat level and the single nanofibre level. The electrochemical performance of SKL CNFs was characterized for functional applications at the nanofibre mat level. This research harnessed different processing methods through hierarchical improvements of the mechanical properties of SKL CNF. The mechanical properties of SKL nanofibre mats were improved by the reduction of nanofibre diameter through the optimization of electrospinning process. The mechanical properties of SKL nanofibres gained an order of magnitude improvement through heat treatment processes of thermo-stabilization and carbonization. Aligned nanofibre mats were successfully fabricated via the rotating drum method resulting in further enhancement of the mechanical properties of SKL CNF. Single-walled carbon nanotube (SWNT)-SKL core-shell composite nanofibres were successfully fabricated via the emulsion electrospinning process. The mechanical properties of the SWNT/SKL composite nanofibres were found to increase as the percent of SWNT increases. This research also investigated the mechanical properties translation between SKL single nanofibres and their fibre assemblies. The mechanical properties of the SKL single nanofibres were characterized and then analyzed by the statistical Weibull distribution. The experimental results were in good agreement with the analytical values. A prototype supercapacitor (SC) cell using SKL-based CNF as binder-free electrodes was constructed to demonstrate the feasibility of the SKL CNF for functional applications. The electrochemical performance of the SC cell was characterized and the energy density and power density of the SC cell were found to meet the requirement for commercial products. In summary, this research sheds light on our understanding of the mechanism of the mechanical properties improvement of SKL CNF, which helps guide the tailoring of the mechanical performance of SKL CNF. Moreover, the electrochemical performance of SKL-based CNFs demonstrated that they are promising candidates as electrode materials for SC and a wide range of energy storage devices.

description: This research investigates how future oriented phrases are constructed in Tlingit, a branch of the Na-Dene Athabaskan language family, spoken in Southeast Alaska, the Yukon, and parts of northern BC. Utilizing semantic fieldwork elicitation methods this work presents a thorough semantic analysis of a prospective trimorphemic aspect cluster necessary for a future reading, and contributing to a missing part of theoretical understanding in the Tlingit linguistic literature. Because the three morphemes under discussion are triggered in other verbal environments, a clearer semantic understanding of how they function will also present interesting theoretical questions for future research, as well as provide the building blocks for teaching second language learners about this cluster.

description: We compute the QCD phase diagram in the plane of the chiral chemical potential and temperature using the linear sigma model coupled to quarks and to the Polyakov loop. The chiral chemical potential accounts for effects of imbalanced chirality due to QCD sphaleron transitions which may emerge in heavy-ion collisions. We found three effects caused by the chiral chemical potential: the imbalanced chirality (i) tightens the link between deconfinement and chiral phase transitions; (ii) lowers the common critical temperature; (iii) strengthens the order of the phase transition by converting the crossover into the strong first order phase transition passing via the second order end-point. Since the fermionic determinant with the chiral chemical potential has no sign problem, the chirally imbalanced QCD matter can be studied in numerical lattice simulations.

description: Cash transfer studies have focused much on the economic dimensions of the programmes as an indication of their capacity to combat poverty and vulnerabilities with little attention directed to their implications on gender relations especially in Sub-Saharan Africa (SSA). Using a qualitative research methodology, the study examined the implications of the longterm state-implemented Malawi Social Cash Transfer Programme (SCTP) on gender relations at household level at Traditional Authority (TA) Chamba in Machinga district. It specifically explored how the programme affected gender-related conflicts, decision making, traditional stereotyped gender roles and anti-social expenditures in beneficiary households. The study found that the programme has positive implications on household’s gender relations. In fact, the programme reduced intrahousehold gender conflicts by improving the bargaining power of women, lessening poverty related stresses as well as through awareness raising on programme objectives and threats of deregistration. The programme also improved joint decision making over household expenditures and investments. Notwithstanding the positive gender implications, the programme reinforces some traditional gender roles and stereotypes by promoting the perception that women are primary caregivers and household managers while men are extravagant and self-serving. Basing on the findings, this study recommends that it is essential to build the knowledge and skills of programme implementers on gender and enlighten them on unintended adverse consequences that could arise from the implementation of Malawi Social Cash Transfer Programme. There is also a need to complement the programme with interventions specifically designed to overcome inequalities between men and women by raising awareness about women’s rights and addressing power imbalances between men and women at household and community level. The findings of this study provide an important body of knowledge regarding the gender implications of the long-term government-implemented cash transfer programmes in development context. Due to non-generalizable nature of the findings, the study recommends conducting a similar study at national level.

description: Objectives: This study aims to compare the developmental profile of severe acute malnourished (SAM) and normal under-five children and to find sociodemographic determinants accountable for their developmental disabilities. Setting: We conducted a multi-centre cross-sectional study in three basic health units and one rural health centre in Pakistan. Participants: 200 children (SAM and healthy) aged 6-59 months. Primary and secondary measures: We screened for nutritional status and clinical complications. Children underwent for developmental assessment by Denver Development Screening Tool II. A pretested structured questionnaire on sociodemographic characteristics and nutrition was used for collecting data about determinants of developmental delay. Results: We observed statistically significant differences in anthropometric measurements among SAM compared with normal nourished in weight, height, mid-upper arm circumference and weight-for-height z-scores. SAM serves as a significant risk factors (p<0.001) for delayed personal or social development (69% vs 11%; OR (95% CI)=18.01 (8.45 to 38.37)), delayed fine motor development (39% vs 8%; OR (95% CI)=7.35 (3.22 to 16.81)), delayed language development (32% vs 8%; OR (95% CI)=5.41 (2.35 to 12.48)), delayed gross motor development (34% vs 10%; OR (95% CI)=4.64 (2.14 to 10.05)) and delayed global development (66% vs 20%; OR (95% CI)=7.77 (4.09 to 14.74)). Applying logistic regression, personal or social development (p<0.001) and language development (p<0.05), under-five siblings was a risk factor, while among gross motor development, mother's educational status (p<0.05) was a significant risk factor for developmental delay. Conclusions Our analysis indicates that children with malnutrition have a high frequency of developmental delays. Missing maternal education and a higher number of under-five siblings are also potential risk factors for developmental delay.

description: A new phosphole derivative, 2,5-di(2-quinolyl)-1-phenylphosphole (1), was synthesized by using the Fagan–Nugent method. Phosphole 1 was obtained as an air-stable solid in high yield (73%). Additionally, two new copper–phosphole complexes, [CuX(Phosphole)2] (X = Cl (2a), I (2b), Phosphole=1), have been synthesized by reaction of CuX (X = Cl, I) and 1. All compounds were characterized by NMR, ESI-MS, UV–Vis, and fluorescence spectroscopy. The photophysical properties of all compounds were analyzed. UV–Vis spectra of 2a-b show π–π* transitions with shifts very similar to the free phosphole due to that their symmetrical structures inhibiting an efficient intraligand charge transfer, ILCT. Compounds 1, 2a-b exhibit fluorescence between 460 and 583 nm with quantum yields of Φf =0.04 − 0.11. The emission energy of 2b is higher than 2a, suggesting that λ max is affected by the ligand-field strength of the halide in the complexes (I¯ < Cl¯). The suggested structures of 2a-b were analyzed computationally at the PBEPBE/def2svp level of theory. The rotation barrier of the quinolyl group was analyzed by a scan analysis. Then, the 3 D structures of 2a-b were obtained in good agreement with the experimental results.

description: Fiber-optic sensors were developed for monitoring dissolved carbon dioxide in water samples in the 0 to 900 ppm concentration range. A pH-sensitive fluorescent dye (HPTS) was reacted with a cationic quaternary ammonium salt to form an ion pair which was electrostatically bound to the surface of particles of aminocellulose which then were dispersed into a gas-permeable silicone polymer. The green fluorescence of the base form was monitored using a fiber optic fluorometer. The use of the aminocellulose enhanced the stability and lifetime of the sensor and also increased the fluorescence of the sensor membrane because the particles act as scattering centers. The characteristics of the sensors are described with respect to dynamic range, reproducibility, long-term stability and temperature dependence.
