description: The present study aimed to explore whether lesbian women’s preferences for a sperm donor or a long-term mate show a pattern similar to those of heterosexual women. Three hundred and eighty-three donor insemination patients, of whom 278 were heterosexual and 105 were lesbian, completed a questionnaire comprising a series of 35 traits and rated the importance of each trait in a sperm donor and again in a long term mate. Results showed that traits relating to socioeconomic status, genetic background and general health, physical appearance, and personality were rated by lesbian women as more important in a long-term mate than in a sperm donor. It was further found that both heterosexual and lesbian women attached higher importance to the socioeconomic status, personality and physical appearance of the long-term mate than of the sperm donor; heterosexual women attached similar importance to the genes and health of a long-term mate and a sperm donor, while lesbian women attached greater importance to the genetic background and general health of the sperm donor than those of a long-term mate. The implications and interpretations of the findings are discussed in light of Trivers’ parental investment theory.

description: Half life values for proton radioactivity in nuclei have been calculated in the WKB approximation. The microscopic proton-nucleus potential has been obtained by folding the densities of daughter nuclei with two microscopic NN interactions, DDM3Y and JLM. The densities have been obtained in the Relativistic Mean Field approach in the spherical approximation using the force FSU Gold. No substantial modification of results has been observed if other common forces are employed. The calculated results for the decays from the ground state or the low-lying excited states in almost all the nuclei agree well with experimental measurements. Reasons for large deviations in a few cases have been discussed. Results in $^{109}$I and $^{112,113}$Cs show that the effect of deformation is small contrary to earlier calculations. Predictions for possible proton radioactivity have been made in two nuclei, $^{93}$Ag and $^{97}$In.

description: Among reproductive health problems, idiopathic infertility affects married couples. The current diagnosis of male infertility focuses on the concentration, motility, and morphology of sperm in the ejaculate. Since the molecular mechanism of idiopathic infertility is unknown, identification of Differentially Expressed Genes (DEGs) among the control and idiopathic infertile male can shed light on diagnosis and treatment. Here, we analyzed the dataset GSE65683 to identify DEGs in idiopathic human sperm in three groups of patients: (i) Timed Intercourse (TIC); (ii) Intrauterine Insemination (IUI); and (iii) Assisted Reproductive Technology (ART). The enrichment analysis was carried out using DAVID (Database for Annotation, Visualization and Integrated Discovery) and GeneCodis for the DEGs. Protein-Protein Interaction (PPI) network of these DEGs were constructed using the STRING database. The network parameters such as degree and betweenness were calculated to select the important hubs. In total, 118 DEGs in TIC, 446 in IUI, and 188 in ART were identified. PPI network was constructed and identified critical top hub genes such as ACTB, BTBD6, EIF2S3, EIF3A, EIF4E, POLR2L, RPL4, RPL7, RPS11, RPL13, RPS15, RPL23, RPL27, RPL9, RPLP0 and UBA52 that may play an essential role in idiopathic male infertility. Thus, the identified hub genes may provide an insight into the molecular mechanism and contribute to discovering novel therapeutic targets and developing new strategies for idiopathic male infertility.

description: This study explores the role of external audiences in determining the importance of family firm brands and the relationship with firm performance. Drawing on text mining and social network analysis techniques, and considering the brand prevalence, diversity, and connectivity dimensions, we use the semantic brand score to measure the importance the media give to family firm brands. The analysis of a sample of 52,555 news articles published in 2017 about 63 Italian entrepreneurial families reveals that brand importance is positively associated with family firm revenues, and this relationship is stronger when there is identity match between the family and the firm. This study advances current literature by offering a rich and multifaceted perspective on how external audiences perceptions of the brand shape family firm performance.

description: We examine through numerical calculation the collision of counter-propagating trains of optically spaced electron/positron microbunches in a 1 TeV collider scenario for a dielectric laser accelerator (DLA). A time-dependent envelope equation is derived for arbitrary number of bunches in the classical limit, with inclusion of the radiation reaction force (RRF). Example parameters are examined based on a constrained luminosity relation that takes into account the bunch charge for optimal efficiency, material damage limits, and power constraints. We find that for initially identical counter-propagating Gaussian bunch trains the periodic temporal structure leads to a peak in luminosity with number of bunches. For longer bunch trains, the enhancement then decreases inversely with number of bunches. The corresponding fractional energy loss of the beam is found to be of order 1.75\%, which is reduced to 0.35\% when the nonlinear radial dependence of the transverse force is included, with an average beamstrahlung parameter of 0.075, an important result considering that beamstrahlung losses are a critical concern for future TeV colliders.
Black Poverty Leads White Americans to Blame Racial Inequality on Black Americans Themselves
Creators: name: Sommet, Nicolas
name: Payne, B. Keith
Publisher: name: SAGE Publications
Year: 2025

description:
In this article, we argue that White Americans exposed to Black poverty may rationalize racial inequality in ways that deflect blame from their own racial group. In Study 1 (11,855 participants; 537 counties), White Americans in counties with higher Black poverty rates were ironically more likely to believe in racial equality of opportunity, while Black residents were less likely. In Study 2 (4,297 participants; 227 counties), White Americans living in counties with higher Black poverty attributed racial inequality to more internal causes (lack of effort), which predicted reduced support for racial equity policies. In Study 3 (1,036 participants), White Americans experimentally exposed to Black poverty made more internal attributions, an effect mediated by increased interracial anxiety and identity threat. Effects on external attributions were inconsistent across studies. We discuss how internal attributions function as a psychological tool for White Americans to deflect negative emotions and maintain a positive group identity.

description: ICSI is widely recommended for patients undergoing preimplantation genetic testing (PGT), but are sperm a potential source of paternal cell contamination in PGT? Semen samples were obtained from five normozoospermic men consenting to research. From each sample 1, 2, 4, 8 and 10 sperm were collected in PCR tubes and whole genome amplification according to PGT-A and PGT-SR processing protocols was undertaken. None of the 25 samples submitted (a total of 125 sperm) showed evidence of DNA amplification. Thus, paternal cell contamination resulting from using conventional in vitro fertilization (IVF) as the insemination method, carries a low risk of an adverse event or misdiagnosis in PGT-A. Due to the higher risk incurred with PGT-SR, clinics may wish to exercise increased caution and continue using ICSI, while PGT-M involves different processing protocols, presenting a different risk profile.

description: The binding energy and wavefunctions of two-dimensional indirect biexcitons are studied analytically and numerically. It is proven that stable biexcitons exist only when the distance between electron and hole layers is smaller than a certain critical threshold. Numerical results for the biexciton binding energies are obtained using the stochastic variational method and compared with the analytical asymptotics. The threshold interlayer separation and its uncertainty are estimated. The results are compared with those obtained by other techniques, in particular, the diffusion Monte-Carlo method and the Born-Oppenheimer approximation.

description: $^4$He confined in nanoporous Gelsil glass is a unique, strongly correlated Bose system exhibiting quantum phase transition (QPT) by controlling pressure. Previous studies revealed that the QPT occurs with four - dimensional (4D) XY criticality, which appears in the zero-temperature limit of the superfluid density. However, the $P-T$ phase diagram also suggested that 4D XY nature appears at finite temperatures. Here, we have determined the critical exponent of the superfluid density of $^4$He in two Gelsil samples that have pore diameter to be about 3 nm, using a newly developed mechanical resonator technique. The critical exponent $ζ$ in the powerlaw fitting $ρ_{\mathrm s} \propto \left| 1 - T/T_{\mathrm c} \right| ^ζ$, where $T_{\mathrm c}$ is the superfluid transition temperature, was found to be 1.0 $\pm$ 0.1 for all pressures realized in this experiment, 0.1 $

description: We present phase-resolved low resolution infrared spectra of the polar EF Eridani obtained over a period of 2 years with SPEX on the IRTF. The spectra, covering the wavelength range 0.8 to 2.4 microns, are dominated by cyclotron emission at all phases. We use a ``Constant Lambda'' prescription to attempt to model the changing cyclotron features seen in the spectra. A single cyclotron emission component with B = 12.6 MG, and a plasma temperature of kT = 5.0 keV, does a reasonable job in matching the features seen in the H and K bands, but fails to completely reproduce the morphology shortward of 1.6 microns. We find that a two component model, where both components have similar properties, but whose contributions differ with viewing geometry, provides an excellent fit to the data. We discuss the implications of our models and compare them with previously published results. In addition, we show that a cyclotron model with similar properties to those used for modeling the infrared spectra, but with a field strength of B = 115 MG, can explain the GALEX observations of EF Eri.

description: Energy levels, magnetic dipole, and electric quadrupole hyperfine structure of the superheavy element rutherfordium (Rf, $Z$=104) and its first three ions are calculated using a combination of the configuration interaction, coupled-cluster single-doubles, and many-body perturbation theory techniques. The results are to be used in future interpretations of the measurements in terms of nuclear magnetic dipole and electric quadrupole momenta. To have a guide on the accuracy of the study, we perform similar calculations for hafnium (Hf, $Z$=72) and its ions. Hf is a lighter analog of Rf with a similar electronic structure. Good agreement with the experiment for Hf and with available previous calculations of the energy levels of Rf is demonstrated.

description: We investigate the time evolution of the mass distribution of pre-stellar cores (PSCs) and their transition to the initial stellar mass function (IMF) in the central parts of a molecular cloud (MC) under the assumption that the coalescence of cores is important. Our aim is to explain the observed shallow IMF in dense stellar clusters such as the Arches cluster. The initial distributions of PSCs at various distances from the MC center are those of gravitationally unstable cores resulting from the gravo-turbulent fragmentation of the MC. As time evolves, there is a competition between the PSCs rates of coalescence and collapse. Whenever the local rate of collapse is larger than the rate of coalescence in a given mass bin, cores are collapsed into stars. With appropriate parameters, we find that the coalescence-collapse model reproduces very well all the observed characteristics of the Arches stellar cluster IMF; Namely, the slopes at high and low mass ends and the peculiar bump observed at ~5-6 M_sol. Our results suggest that today's IMF of the Arches cluster is very similar to the primordial one and is prior to the dynamical effects of mass segregation becoming important

description: Carrier-doped transition metal dichalcogenide (TMD) monolayers are of great interest in valleytronics due to the large Zeeman response (g-factors) in these spin-valley-locked materials, arising from many-body interactions. We develop an \textit{ab initio} approach based on many-body perturbation theory to compute the interaction-enhanced g-factors in carrier-doped materials. We show that the g-factors of doped WSe$_2$ monolayers are enhanced by screened exchange interactions resulting from magnetic-field-induced changes in band occupancies. Our interaction-enhanced g-factors $g^*$ agree well with experiment. Unlike traditional valleytronic materials such as silicon, the enhancement in g-factor vanishes beyond a critical magnetic field $B_c$ achievable in standard laboratories. We identify ranges of $g^*$ for which this change in g-factor at $B_c$ leads to a valley-filling instability and Landau level alignment, which is important for the study of quantum phase transitions in doped TMDs. We further demonstrate how to tune the g-factors and optimize the valley-polarization for the valley Hall effect.

description: This study aims to understand differences/similarities in the genetic profile of the endometrium at the start of window of implantation (WOI) in women with unexplained infertility (UI) and unexplained recurrent pregnancy loss (uRPL). Differentially expressed genes (DEGs) from the endometrium were evaluated using gene expression array and pathway enrichment analysis was performed to analyse gene expression pathways involved in both conditions. We found 2,171 genes arranged in 117 pathways and 730 genes arranged in 33 pathways differentially expressed in endometrium of patients in UI and uRPL, respectively. Complement-coagulation cascades, morphine addiction pathway, and PI3K-Akt signalling pathway were predominantly differentially expressed in UI. Cancer pathways, NF-κB signalling pathway, and actin cytoskeleton regulation pathway showed significant changes in uRPL. Forty-eight percent of DEGs and 84% of differentially expressed pathways in uRPL were found in the endometrium of UI patients. Unexpected close association in gene expression pathways between UI and uRPL is observed supporting the hypothesis ‘uRPL is a clinical subset of UI’. Yet 100% DEGs overlap wasn’t found suggesting the endometrium has still some different gene expression patterns at start of WOI in UI and uRPL. Lastly, diagnostic tools may be developed for uRPL because more specific genes-pathways are involved compared with UI, which shows broader genetic expression profile.

description: The Mann-Marolf surface term is a specific candidate for the "reference background term" that is to be subtracted from the Gibbons-Hawking surface term in order make the total gravitational action of asymptotically flat spacetimes finite. That is, the total gravitational action is taken to be: (Einstein-Hilbert bulk term) + (Gibbons-Hawking surface term) - (Mann-Marolf surface term). As presented by Mann and Marolf, their surface term is specified implicitly in terms of the Ricci tensor of the boundary. Herein I demonstrate that for the physically interesting case of a (3+1) dimensional bulk spacetime, the Mann-Marolf surface term can be specified explicitly in terms of the Einstein tensor of the (2+1) dimensional boundary.

Synemosyna formica Hentz, 1846 (by original designation).
Diagnosis (modified from Perger & Rubio 2020a)
Species of Synemosyna can be distinguished from those of Fluda Peckham & Peckham, 1892 and Erica Peckham & Peckham, 1892 by a carapace laterally constricted (continuous in the latter genera) and an epigyne with a single opening (2–3 in the latter genera), and from those of Sympolymnia Perger & Rubio, 2020 by a fusiform abdomen that is longer than the carapace, the carapace with at the most one lateral white patch, and spermathecae small, globular, pear- or kidney-shaped (abdomen ovate, carapace with 2 lateral white patches and spermathecae lung-shaped in Sympolymnia). Cylistella Simon, 1901 has a rounded, beetle-like habitus without constrictions and is the morphologically most distinct group within this tribe.

ESR and microwave conductivity studies in DEM(TCNQ) above room temperature

description: Two phase transitions have been found in DEM(TCNQ)₂ at 400(3) K and at 442(6) K to 453(6) K using ESR and measurements of the microwave conductivity. These temperatures are less than the values of 415 K and 483 K previously obtained from temperature dependent Guinier measurements. Below 400(3) K two ESR lines, I and II are observed corresponding to the two stacks, B and A, in DEM(TCNQ)₂. Above 400(3) K and below 453(6) K only one line remains with the same g value as line I. The angular dependence of the g value was fitted to g[sub=‖]² = g[sub=⊥] ²cos2θ + g²sinθ and values of g[sub=⊥] = 2.003551(14) and g[sub=‖] = 2.00273015) were obtained. Between 298 K and 442(6) K the conductivity was that of a semiconductor with an exitation energy E[sub=0] = 0.385(52) e.v. The -4k[sub=⌐] phase transition is postulated at 447(9) K. The phase transition at 400(3) K is due to a transfer of spin density from stack A to stack B, and has no effect on the total spin susceptibility or on the conductivity to within the experimental error.

The branching ratios of these decay processes are calculated with the flavor SU(3) symmetry. The uncertainties are estimated by considering the SU(3) breaking effect. We find that the decay rates are very tiny in the framework of the Standard Model. We also estimate the sensitivities of the measurements of these rare decays at the future experiments, such as BES-III, super-$B$ and LHC-$b$.

anti-tax loss trafficking

description: Anti-tax loss trafficking rules disallow the use of loss carryforwards after a change in ownership or activity (such as significant changes in turnover, employment, or the product portfolio). This restriction could threaten accumulated loss carryforwards of start-ups. Accounting for the increased risk and reduced return on their investment, VC investors could reduce their funding. I analyze whether the venture capital (VC) funding of start-ups in Europe is affected by these regulations. I base my empirical analysis on several case studies and a panel analysis covering VC-funded companies in the EU28 Member States from 1999 to 2014. My findings suggest that strict anti-tax loss trafficking rules indeed impair VC funding. Especially more mature companies and companies in high-tech industries are affected.

description: The purpose of this study was to evaluate the incidence of unbalanced chromosome rearrangement in blastocyst-stage embryos from carriers of pericentric inversion of chromosome 1 (PEI-1). A total of 98 embryos from 22 PEI-1 carriers were tested for unbalanced rearrangements, originating from inversion carriers, and overall aneuploidy. Logistic regression analysis indicated that the ratio of inverted segment size to chromosome length was a statistically significant risk factor for unbalanced chromosome rearrangement from PEI-1 carriers (p = 0.003). The optimal cut-off values to predict the risk of unbalanced chromosome rearrangement was 36%, with the incidence being 2.0% in the <36% group and 32.7% in the ≥36% group. The unbalanced embryo rate was 24.4% in male carriers compared to 12.3% in female carriers. Inter-chromosomal effect analysis was performed using 98 blastocysts from PEI-1 carriers and 116 blastocysts from age-matched controls. PEI-1 carriers had similar sporadic aneuploidy rates compared to those of age-matched controls at 32.7 vs. 31.9%, respectively. In conclusion, the risk of unbalanced chromosome rearrangement is affected by inverted segment size in PEI-1 carriers.

description: Hydractinia is a sessile, colonial invertebrate and a member of the phylum Cnidaria. They possess a remarkable population of adult stem cells known as i-cells which are the source of Hydractinias impressive regenerative ability. Previous work had identified the presence of i-cells during embryogenesis and metamorphosis. I was able to show the first appearance of putative i-cell progenitors in early embryogenesis in Hydractinia. i-cell progenitors first appeared at the 32/64-cell stage, often with many individual cells at once expressing Piwi1 (which is an i-cell marker). The true developmental potential of these putative i-cell progenitors remains to be studied. Past studies have shown that a population of i-cells can give rise to all somatic cell lineages as well as germ cells in Hydractinia. However, whether this population consisted of distinct, lineage-committed i-cells or pluripotent cells has not yet been confirmed. This work determines the developmental potential of a single i-cell in Hydractinia. Making use of Hydractinia’s remarkable growth, plasticity, I established a method for transferring a single i-cell from a double transgenic Piwi1::GFP Beta-Tubulin::mScarlet reporter colony into a wild type animal via stolonal contact. This method allowed tracing all progeny of a single grafted icell in the host tissue in vivo. I observed that wild type Hydractinia tissue possessing an initial single transgenic donor i-cell developed into a chimeric animal with a mixture of cells derived from the transgenic donor and the wild type recipient. Donor-derived cells, representing all major somatic lineages and germ cells were scattered in the recipient’s tissues in both feeding and sexual polyps, and in the stolonal compartment. This study shows that Hydractinia possesses pluripotent i-cells. Additionally, somatic cell types in Hydractinia did not exhibit any stem cell like qualities such as continuous proliferation and passive displacement.

description: We consider $d>4$-dimensional space-times which are asymptotically flat at spatial infinity and show that, in the first order framework, the action principle is well-defined \emph{without the need of infinite counter terms.} It naturally leads to a covariant phase space in which the Hamiltonians generating asymptotic symmetries provide the total energy-momentum and angular momentum of the isolated system. This work runs parallel to our previous analysis in four dimensions \cite{aes}. The higher dimensional analysis is in fact simpler because of absence of logarithmic and super translation ambiguities.

Shaping Planetary Nebulae by Light Jets

description: We conduct numerical simulations of axisymmetrical jets expanding into a spherical AGB slow wind. The three-dimensional flow is simulated with an axially symmetric numerical code. We concentrate on jets that are active for a relatively short time. Our results strengthen other studies that show that jets can account for many morphological features observed in planetary nebulae (PNs). Our main results are as follows. (1) With a single jet's launching episode we can reproduce a lobe structure having a `front-lobe', i.e., a small bulge on the front of the main lobe, such as that in the PN Mz~3. (2) In some runs dense clumps are formed along the symmetry axis, such as those observed in the pre-PN M1-92. (3) The mass loss history of the slow wind has a profound influence on the PN structure. (4) A dense expanding torus (ring; disk) is formed in most of our runs. The torus is formed from the inflated lobes, and not from a separate equatorial mass loss episode. (5) The torus and lobes are formed at the same time and from the same mass loss rate episode. However, when the slow wind density is steep enough, the ratio of the distance divided by the radial velocity is larger for regions closer to the equatorial plane than for regions closer to the symmetry axis. (6) With the short jet-active phase a linear relation between distance and expansion velocity is obtained in many cases. (7) Regions at the front of the lobe are moving sufficiently fast to excite some visible emission lines.

description:  

The Data Readiness Framework was developed in support of the EOSCLIMA proposal by the consortium responding to the call.

From the proposal text: "EOSCLIMA will deliver a Data Readiness and FAIRness Framework (DaReFF) to support researchers contributing to the adaptation to climate change in understanding, adopting, and capitalising on FAIR and open data practices. [...] The framework allows assessment of the FAIRness and the readiness level of research data from a publication-, reproducibility-, analysis-, decision- (and machine-processing readiness) perspective [...]. It helps the researchers identify shortcomings in terms of FAIR and open data practices and provides them with suggestions in terms of tools that can be adopted to fill such gaps. Finally, it also helps the researchers in documenting the benefits of using FAIR and open data practices as the new norm. "

description: The regions in the Minimal Supersymmetric Standard Model with the minimal amount of fine-tuning of electroweak symmetry breaking are presented for general messenger scale. No a priori relations among the soft supersymmetry breaking parameters are assumed and fine-tuning is minimized with respect to all the important parameters which affect electroweak symmetry breaking. The superpartner spectra in the minimally tuned region of parameter space are quite distinctive with large stop mixing at the low scale and negative squark soft masses at the high scale. The minimal amount of tuning increases enormously for a Higgs mass beyond roughly 120 GeV.

The nature of constructs in social psychological research
Creators: name: Zerbe, Wilfred Joachim
Publisher: name: University of British Columbia
Year: 2010

description: A fundamental assumption in social psychological research, that the construct underlying conditions in an experiment is stable and varies only in quantity across conditions, is explored. It is argued that instead the result of the manipulation of the independent variable is a qualitative difference between the relevant psychological constructs. A distinction is made between theories of empirical constructs and those which posit unobservable, hypothetical constructs. The assumption of construct stability relates only to theories of relationships between hypothetical constructs. The lack of direct access to the identity of geno-typic processes underlying observable behaviour or manipulations allows the possibility of construct instability. Methods of improving access discussed centre on increasing the number and diversity of observations by repeating the operationalization and measurement of variables in ways different but theoretically tied to the construct of interest. The Q-sort method of correlating behaviour with items descriptive of personality is proposed as a method of examining the identity of constructs and thus of assessing the hypothesis that conditions are qualitatively different. This method is applied to an examination of the relationship between incentive and choice and latency behaviour in the Prisoner's Dilemma game. A significant difference between conditions was found for choice behaviour but not for latency. Q-item—behaviour correlates, however, were different in each condition and for each behaviour, supporting the hypothesis that conditions differ in some meaningful way. A stronger test of the hypothesis involved the construction of templates describing the ideal-personality most likely to exhibit the designated behaviour. These templates were able to predict behaviour within conditions and, in agreement with the hypothesis, no predictability was found across conditions. However, within-condition validation coefficients were very low, such that the across conditions results were uninterpretable. It was concluded that the Q-sort method, while attractive, is constrained in its usefulness and ability to test the hypothesis. Discussion included examination of the link between qualitative differences and person by situation interaction. It was recommended that social psychology improve its recognition of methodological assumptions made and of how these and theories of social behaviour are interrelated.

description: Chemically functionalized single-walled carbon nanotubes (SWNTs) have shown promise in tumor targeted accumulation in mice and exhibit biocompatibility, excretion and little toxicity. Here, we demonstrate in-vivo SWNT drug delivery for tumor suppression in mice. We conjugate paclitaxel (PTX), a widely used cancer chemotherapy drug to branched polyethylene-glycol (PEG) chains on SWNTs via a cleavable ester bond to obtain a water soluble SWNT-paclitaxel conjugate (SWNT-PTX). SWNT-PTX affords higher efficacy in suppressing tumor growth than clinical Taxol in a murine 4T1 breast-cancer model, owing to prolonged blood circulation and 10-fold higher tumor PTX uptake by SWNT delivery likely through enhanced permeability and retention (EPR). Drug molecules carried into the reticuloendothelial system are released from SWNTs and excreted via biliary pathway without causing obvious toxic effects to normal organs. Thus, nanotube drug delivery is promising for high treatment efficacy and minimum side effects for future cancer therapy with low drug doses.

description: The multi-Higgs models having spontaneous CP violation (SPCV) and natural flavor conservation (NFC) lead to a real CKM matrix $V$ contradicting current evidence in favour of a complex $V$. This contradiction can be removed by using a generalized $μ$-$τ$ (called 23) symmetry in place of the discrete symmetry conventionally used to obtain NFC. If 23 symmetry is exact then the Higgs induced flavour changing neutral currents (FCNC) vanish as in case of NFC. 23 breaking introduces SPCV, a phase in $V$ and suppressed FCNC among quarks. The FCNC couplings $F_{ij}^{d,u}$ between $i$ and $j$ generations show a hierarchy $|F_{12}^{d,u}|
