Human Face-Selective Cortex Does Not Distinguish between Members of a Racial Outgroup

Abstract People often fail to individuate members of social outgroups, a phenomenon known as the outgroup homogeneity effect. Here, we used functional magnetic resonance imaging (fMRI) repetition suppression to investigate the neural representation underlying this effect. In a preregistered study, White human perceivers (N = 29) responded to pairs of faces depicting White or Black targets. In each pair, the second face depicted either the same target as the first face, a different target from the same race, or a scrambled face outline. We localized face-selective neural regions via an independent task, and demonstrated that neural activity in the fusiform face area (FFA) distinguished different faces only when targets belonged to the perceivers’ racial ingroup (White). By contrast, face-selective cortex did not discriminate between other-race individuals. Moreover, across two studies (total N = 67) perceivers were slower to discriminate between different outgroup members and remembered them to a lesser extent. Together, these results suggest that the outgroup homogeneity effect arises when early-to-mid-level visual processing results in an erroneous overlap of representations of outgroup members.
Nitrogenous excretion in juvenile turbot, Scophthalmus maximus (L.), under controlled conditions

Laboratory experiments on juvenile turbot. Scophthalmus maximus (L.), were carried out under controlled temperature (12°C) and feeding regimes in a flow-through system. Monitoring of total ammonia nitrogen (TAN) and urea nitrogen (Urea-N) was performed through continuous sampling of the effluent sea water. The effects of ingested nitrogen levels on TAN and Urea-N daily and hourly excretion rates were studied. Strong relationships were found between ingested nitrogen, and both TAN and Urea-N excretion for both daily and hourly maximum excretion rates. Turbot showed a low metabolic activity, confirmed by low excretion levels. Daily patterns for TAN and Urea-N production were different, suggesting specific physiological phenomenon for urea excretion mechanisms. The question of whether turbot are partly ureotelic or ureogenic is underlined.
Above-Ground Biomass Retrieval over Tropical Forests: A Novel GNSS-R Approach with CyGNSS

An assessment of the National Aeronautics and Space Administration NASA’s Cyclone Global Navigation Satellite System (CyGNSS) mission for biomass studies is presented in this work on rain, coniferous, dry, and moist tropical forests. The main objective is to investigate the capability of Global Navigation Satellite Systems Reflectometry (GNSS-R) for biomass retrieval over dense forest canopies from a space-borne platform. The potential advantage of CyGNSS, as compared to monostatic Synthetic Aperture Radar (SAR) missions, relies on the increasing signal attenuation by the vegetation cover, which gradually reduces the coherent scattering component σ coh , 0 . This term can only be collected in a bistatic radar geometry. This point motivates the study of the relationship between several observables derived from Delay Doppler Maps (DDMs) with Above-Ground Biomass (AGB). This assessment is performed at different elevation angles θ e as a function of Canopy Height (CH). The selected biomass products are obtained from data collected by the Geoscience Laser Altimeter System (GLAS) instrument on-board the Ice, Cloud, and land Elevation Satellite (ICESat-1). An analysis based on the first derivative of the experimentally derived polynomial fitting functions shows that the sensitivity requirements of the Trailing Edge TE and the reflectivity Γ reduce with increasing biomass up to ~ 350 and ~ 250 ton/ha over the Congo and Amazon rainforests, respectively. The empirical relationship between TE and Γ with AGB is further evaluated at optimum angular ranges using Soil Moisture Active Passive (SMAP)-derived Vegetation Optical Depth ( VOD ), and the Polarization Index ( PI ). Additionally, the potential influence of Soil Moisture Content (SMC) is investigated over forests with low AGB.
Development of specific rRNA probes to distinguish between geographic clades of the Alexandrium tamarense species complex

The globally occurring Alexandrium tamarense/fundyense/catenella species complex consists of toxic and non-toxic strains that are morphologically difficult to distinguish. We developed four specific ribosomal RNA probes that can identify the entire species complex, the strains of the toxic . orth American clade and the strains of the two non-toxic clades from Western Europe and the Mediterranean Sea by DNA dot blot and fluorescence in situ hybridization. These probes are a first step for the development of an early warning system for the presence of A. tamarense.
Lekking by default: female habitat preferences and male strategies in Uganda kob

In lek-breeding ungulates, males defend small territories clustered on traditional mating grounds called leks. One explanation for the evolution of lek-breeding is that males hold lek territories as a default strategy when they cannot monopolize females by defending female home ranges, stable female groups or predictable resource patches. The assumptions of this explanation were tested by comparing the distribution of males, females and resources in a lekking antelope, the Uganda kob (Kobus kob thomasi) in Queen Elizabeth National Park, Uganda. Methods included repeated censuses along transects and multiple Poisson regression. Female kob were associated strongly with short, green grass and more weakly with particular growth stages, vegetation communities and landforms
HMGA2 variants in Silver-Russell syndrome: homozygous and heterozygous occurrence.

CONTEXT Silver-Russell syndrome (SRS) is a clinical and molecular heterogeneous disorder, associated with short stature, typical facial gestalt, and body asymmetry. Though molecular causes of SRS can be identified in a significant number of patients, about half of patients currently remain without molecular diagnosis. However, determination of the molecular cause is required for a targeted treatment and genetic counselling. OBJECTIVE Aim of the study was to corroborate the role of HMGA2 as SRS causing gene and reevaluate its mode of inheritance. DESIGN, SETTING, PATIENTS Patients were part of an ongoing study aiming on SRS causing genes. They were classified according to the Netchine-Harbison clinical scoring system, DNA samples were investigated by whole exome sequencing. Common molecular causes of SRS were excluded before. RESULTS Three novel pathogenic HMGA2 variants were identified in five patients from three SRS families, and fulfilling diagnostic criteria of SRS. For the first time homozygosity for a variant in HMGA2 could be identified in a severely affected sibpair, whereas parents carrying heterozygous variants had a mild phenotype. Treatment with recombinant growth hormone led to a catch-up growth in one patient, while all other did not receive growth hormone and stayed small. One patient developed a type 2 diabetes at age of 30 years. CONCLUSIONS Identification of novel pathogenic variants confirms HMGA2 as a SRS causing gene, thus HMGA2 testing should be implemented in molecular SRS diagnostic workup. Furthermore, inheritance of HMGA2 is variable depending on the severity of the variant and its consequence for protein function.
Chemical capture of free-ranging red deer (Cervus elaphus) with medetomidine-ketamine

Seventeen free-ranging red deer (Cervus elaphus) (12 calves and 5 yearling hinds) were immobilized with a combination of medetomidine hydrochloride (MED) and ketamine hydrochloride (KET) in winter (January-March). Immobilizations were performed with plastic projectile syringes fired from a dart gun. Mean (SD) doses of 0.147 (0.024) mg MED/kg and 2.5 (0.4) mg KET/kg induced recumbency in 5.0 (2.0) minutes in the calves and all of them were completely immobilized. The initial doses in the yearling hinds were 0.099 (0.016) mg MED/kg and 1.9 (0.2) mg KET/kg but three of them required addirional dosing for induction of reliable restraint. The distance covered by the animals between darting and recumbency ranged from 40-250 m for calves and 100-300 m for yearling hinds. The animals were translocated to deer farms for breeding purposes and were given 12.5-25.0 mg of atipamezole hydrochloride before transportation. All animals recovered completely. Haematological and serum biochemical comparisons between free-ranging calves immobilized with medetomidine-ketamine (n=3) and captive unmedicated calves (n=4) showed that chemical capture induce very little stress in red deer.
Clinical significance of neutrophil–lymphocyte ratio and monocyte–lymphocyte ratio in women with hyperglycemia

ABSTRACT Objective: Abnormal pro-inflammatory regulation of the immune system might contribute to the pathogenesis of hyperglycemia during pregnancy. We examined the correlations of neutrophil–lymphocyte ratio (NLR) and monocyte–lymphocyte ratio (MLR) with disease severity and assessed their predictive values. Methods: This retrospective case–control study included 311 cases of hyperglycemia first detected during pregnancy (HFDP) [153 with gestational diabetes mellitus (GDM) and 158 with diabetes in pregnancy (DIP)] and, as a control group, 172 pregnant women with normal glucose tolerance. The NLRs and MLRs were calculated from the blood test data. Results: The absolute leukocyte, neutrophil, monocyte, and lymphocyte counts as well as the NLR and MLR values of HFDP patients significantly differed from control values, but no significant differences were detected in the leukocyte, neutrophil, and monocyte counts of the GDM and DIP groups. Significantly different metrics were selected, binary analysis performed, and odds ratios calculated to identify risk factors. Age, BMI, NLR, and MLR were found to be risk factors for HFDP, and high systolic blood pressure (SBP) at triage and MLR related to the occurrence of DIP. Receiver operating characteristics curve analysis showed that NLR and MLR had better diagnostic accuracy in distinguishing HFDP from controls [NLR area under the curve (AUC) = 0.78; MLR AUC = 0.72] than age and BMI. Values for NLR > 4.394 or MLR > 0.309 correlated with the severity of maternal clinical symptoms and perinatal infant outcomes. MLR was the best predictor of DIP (AUC = 0.72) and MLR values > 0.299 could identify patients at risk for developing DIP and having poor fetal outcomes. Conclusion: Metrics derived from peripheral blood neutrophil, monocyte, and lymphocyte counts are thought to reflect systemic immune-inflammation. Elevated MLR and NLR may be unfavorable prognostic factors for clinical outcomes in patients with hyperglycemia during pregnancy.
A microscopical study of diatom phytoplankton in deep crater Lake El'gygytgyn, Northeast Siberia

Abstract : A survey of the planktonic diatom community was carried out during summer2003 in Lake El’gygytgyn, a deep, cold, low conductive and oligotrophic crater lake inthe Northeast Siberian Arctic. Five planktonic diatom species were identified: Cy-clostephanos dubius , Cyclotella ocellata , Cyclotella tripartita , Pliocaenicus costatus ,and Stephanocostis chantaicus . The morphological details of the five taxa are docu-mented by light and partly also scanning electron micrographs. Additionally, ecologicaland biogeographic data are provided. This is the first evidence of S. chantaicus in a north-east Siberian lake and one of the first findings of P. costatus outside the Baikal Lake re-gion. The diatom community in summer 2003 was almost monospecificly dominated by Cyclotella ocellata (>96%), a species that displays a tremendous morphological variabil-ity. High concentrations and accumulation rates of diatom frustules during the ice-cov-ered period (May–June 2003) indicated considerable under-ice phytoplankton growth.
Differential Changes in Early Somatosensory Evoked Potentials between the Dominant and Non-Dominant Hand, Following a Novel Motor Tracing Task

During training in a novel dynamic environment, the non-dominant upper limb favors feedback control, whereas the dominant limb favors feedforward mechanisms. Early somatosensory evoked potentials (SEPs) offer a means to explore differences in cortical regions involved in sensorimotor integration (SMI). This study sought to compare differences in SMI between the right (Dom) and left (Non-Dom) hand in healthy right-handed participants. SEPs were recorded in response to median nerve stimulation, at baseline and post, a motor skill acquisition-tracing task. One group (n = 12) trained with their Dom hand and the other group (n = 12), with their Non-Dom hand. The Non-Dom hand was significantly more accurate at baseline (p < 0.0001) and both groups improved with time (p < 0.0001), for task accuracy, with no significant interaction effect between groups for both post-acquisition and retention. There were significant group interactions for the N24 (p < 0.001) and the N30 (p < 0.0001) SEP peaks. Post motor acquisition, the Dom hand had a 28.9% decrease in the N24 and a 23.8% increase in the N30, with opposite directional changes for the Non-Dom hand; 22.04% increase in N24 and 24% decrease in the N30. These SEP changes reveal differences in early SMI between Dom and Non-Dom hands in response to motor acquisition, providing objective, temporally sensitive measures of differences in neural mechanisms between the limbs.
EFFECTS OF NITROGEN AND PLANT DENSITY ON DWARF SUNFLOWER HYBRIDS

SUMMARY This research was carried out to determine the seed yield and some yield components of two dwarf hybrids as compared to one standard-height sunflower hybrid (Helianthus annuus L.) at different nitrogen rates and planting densities. The study was carried out under natural rainfed conditions at the Thrace Agricultural Research Institute in Edirne-Turkey between 1999 and 2001. The experiments were set up in split-split plots in a randomized complete block design with three replications. The main plot treatments were three different-height sunflower hybrids, DW-1, DW-2, and Trakya-80. The sub plots were three levels of nitrogen, 0, 60, and 120 kg N/ha. The sub-sub plots were three planting densities, 10 × 70 (142,850 plants/ha), 15 × 70 (95,230 plants/ ha), and 20 × 70 cm (71,430 plants/ha). Based on marginal economic analyses, the economically optimal seed yield per hectare was obtained at 50 kg N/ ha for DW-1 and at 80 kg N/ha for DW-2 and Trakya-80. In all three hybrids, increasing plant densities decreased 1000-seed weight, hull percentage, and head diameter but increased test weight in natural rainfed conditions. The highest seed yield in both dwarf hybrids was obtained with the spacing of 15 × 70 cm (95,230 plants/ha). The results of this research show that nitrogen and plant density have significant effects on seed yield and some yield components of different-height sunflower hybrids.
Investigation of supersonic heat-conductivity hyperbolic waves in radiative ablation flows.

We carry out a numerical investigation of three-dimensional linear perturbations in a self-similar ablation wave in slab symmetry, representative of the shock transit phase of a pellet implosion in inertial confinement fusion (ICF). The physics of ablation is modeled by the equation of gas dynamics with a nonlinear heat conduction as an approximation for radiation transport. Linear perturbation responses of the flow, its external surface, and shock-wave front, when excited by external pressure or heat-flux perturbation pulses, are computed by fully taking into account the flow compressibility, nonuniformity, and unsteadiness. These responses show the effective propagation, at supersonic speeds, of perturbations from the flow external surface through the whole conduction region of the ablation wave, beyond its Chapman-Jouguet point, and up to the ablation front, after the birth of the ablation wave. This supersonic forward propagation of perturbations is evidenced by means of a set of appropriate pseudocharacteristic variables and is analyzed to be associated to the "heat-conductivity" waves previously identified by Clarisse et al. [J. Fluid Mech. 848, 219 (2018)JFLSA70022-112010.1017/jfm.2018. 343]. Such heat-conductivity linear waves are found to prevail over heat diffusion as a feedthrough mechanism [Aglitskiy et al., Philos. Trans. R. Soc. A 368, 1739 (2010)PTRMAD1364-503X10.1098/rsta.2009. 0131] for perturbations of longitudinal characteristic lengths of the order of-or larger than-the conduction region size, and long transverse wavelengths with respect to this region size, and over time scales shorter to much shorter than the shock transit phase duration. This mechanism, which results from the dependency of the heat conductivity on temperature and density in conjunction with a flow temperature stratification, is expected to occur for other types of nonlinear heat conductions-e.g., electron heat conduction-as well as to be efficient at transmitting large scale perturbations from the surrounding of an ICF pellet to its inner compressed core at later times of its implosion. Besides, the proposed set of pseudocharacteristic variables are recommended for analyzing perturbation dynamics in an ablation flow as it furnishes additional propagation information over the fundamental linear modes of fluid dynamics [Kovásznay, J. Aeronautic. Sci. 20, 657 (1953)1936-995610.2514/8.2793], especially in the flow conduction region.
Effect of Impulsivity Traits on Food Choice within a Nudging Intervention

Food choices are often driven by impulsive tendencies rather than rational consideration. Some individuals may find it more difficult resisting impulses related to unhealthy food choices, and low self-control and high impulsivity have been suggested to be linked to these behaviors. Recent shifts have been made towards developing strategies that target automatic processes of decision-making and focus on adjusting the environment, referred to as nudging interventions. Therefore, the purpose of this study was to investigate the effect of impulsivity traits on food choices within a nudging intervention (increased perceived variety). A total of 83 adults participated in an experimental study consisting of a self-service intelligent buffet. Impulsivity traits were measured using the UPPS-P impulsivity scale. General linear models were fitted to evaluate the effect of the five impulsivity traits on the difference of salad consumption (g) between the control and intervention situations. Results showed that impulsivity does not affect food choices in this nudging situation, suggesting that nudging works independently of the participant’s impulsivity score. Results also showed a significantly higher consumption of salad in the nudging versus the control setting (17.6 g, p < 0.05), suggesting that nudging interventions can be effective in significantly increasing total vegetable consumption across the whole impulsivity scale.
Mu opioid receptor knockout mouse: Phenotypes with implications on restless legs syndrome

Restless legs syndrome (RLS) is characterized by an irresistible need to move the legs while sitting or lying at night with insomnia as a frequent consequence. Human RLS has been associated with abnormalities in the endogenous opioid system, the dopaminergic system, the iron regulatory system, anemia, and inflammatory and auto‐immune disorders. Our previous work indicates that mice lacking all three subtypes of opioid receptors have a phenotype similar to that of human RLS. To study the roles of each opioid receptor subtype in RLS, we first used mu opioid receptor knockout (MOR KO) mice based on our earlier studies using postmortem brain and cell culture. The KO mice showed decreased hemoglobin, hematocrit, and red blood cells (RBCs), with an appearance of microcytic RBCs indicating anemia. Together with decreased serum iron and transferrin, but increased ferritin levels, the anemia is similar to that seen with chronic inflammation in humans. A decreased serum iron level was also observed in the wildtype mice treated with an MOR antagonist. Iron was increased in the liver and spleen of the KO mice. Normal circadian variations in the dopaminergic and serotoninergic systems were absent in the KO mice. The KO mice showed hyperactivity and increased thermal sensitivity in wakefulness primarily during what would normally be the sleep phase similar to that seen in human RLS. Deficits in endogenous opioid system transmission could predispose to anemia of inflammation and loss of circadian variations in dopaminergic or serotonergic systems, thereby contributing to an RLS‐like phenotype.
Understanding the role of regulatory flexibility and context sensitivity in preventing burnout in a palliative home care team

Although burnout syndrome has been investigated in depth, studies specifically focused on palliative home care are still limited. Moreover, there is still a lack of evidence regarding the interplay between emotional flexibility and sensitivity to context in preventing burnout in home care settings. For these reasons, the aims of this study were to examine burnout symptoms among practitioners specializing in palliative home care and to investigate the role of regulatory flexibility and sensitivity to context in understanding burnout. An exploratory cross-sectional design was adopted. A convenience sample (n = 65) of Italian specialist palliative care practitioners participated in this study. Participants were recruited between February and April 2019 from two palliative home care services that predominantly cared for end-of-life cancer patients. The Italian version of the Maslach Burnout Inventory (MBI), the Flexible Regulation of Emotional Expression (FREE) scale (a measure of emotional flexibility), and the Context Sensitivity Index (CSI) (a measure of sensitivity to context) were administered. Analyses of variance were conducted using the three MBI factors as dependent variables and profession as an independent variable. Subsequently, three identical analyses of covariance were conducted with age, work experience, flexibility and sensitivity to context as covariates. The results showed a low burnout risk for all three of the MBI factors, and there were no gender differences. An ANOVA revealed a significant effect of profession type and age on the emotional exhaustion factor of the MBI, and an ANCOVA indicated that these effects persisted after covariates were accounted for. The results also showed a significant effect of the FREE score on emotional exhaustion. These findings can help explain the differential contributions of profession type and age to the burnout symptoms investigated. In addition, the emotional flexibility component, as an aspect of resilience, represents a significant and specific factor of emotional exhaustion. Interventions to prevent burnout must consider these relationships.
