Redheaded women are more sexually active than other women, but it is probably due to their suitors

Women with red hair color, i.e., 1–9% of female Europeans, tend to be the subject of various stereotypes about their sexually liberated behavior. The aim of the present case–control study was to explore whether a connection between red hair color and sexual behavior really exists using data from 110 women (34% redheaded) and 93 men (22% redheaded). Redheadedness in women, correlated with various traits related to sexual life, namely with higher sexual desire as measured by Revised Sociosexual Orientation Inventory, with higher sexual activity and more sexual partners of the preferred gender over the past year, earlier initiation of sexual life, and higher sexual submissiveness. Structural equation modelling, however, showed that sexual desire of redheaded women mediated neither their higher sexual activity nor their higher number of sexual partners. These results indirectly indicate that the apparently more liberated sexual behavior in redheaded women could be the consequence of potential mates’ frequent attempts to have sex with them. Our results contradicted the three other tested models, specifically the models based on the assumption of different physiology, faster life history strategy, and altered self-perception of redheaded women induced by stereotypes about them. Naturally, the present study cannot say anything about the validity of other potential models that were not subjects of testing.
Diagnostic Model of in-Hospital Mortality in Patients with Acute ST-Segment Elevation Myocardial Infarction Used Artificial Intelligence Methods : Algorithm Development and Validation

Preventing in-hospital mortality in Patients with ST-segment elevation myocardial infarction (STEMI) is a crucial step.The objective of our research was to to develop and externally validate the diagnostic model of in-hospital mortality in acute STEMI patients used artificial intelligence methods. Methods: As our datasets were highly imbalanced, we evaluated the effect of down-sampling methods. Therefore, down-sampling techniques was additionally implemented on the original dataset to create 1 balanced datasets. This ultimately yielded 2 datasets; original, and down-sampling. We divide non-randomly the American population into a training set and a test set, and anther American population as the validation set. We used artificial intelligence methods to develop and externally validate the diagnostic model of in-hospital mortality in acute STEMI patients, including logistic regression, decision tree, extreme gradient boosting (XGBoost), K nearest neighbor classification model, and multi-layer perceptron.We used confusion matrix combined with the area under the receiver operating characteristic curve (AUC) to evaluate the pros and cons of the above models.The strongest predictors of in-hospital mortality were age, female, cardiogenic shock, atrial fibrillation(AF), ventricular fibrillation(VF),in-hospital bleeding and medical history such as hypertension, old myocardial infarction.The F2 score of logistic regression in the training set, the test set, and the validation data set were 0.7, 0.7, and 0.54 respectively.The F2 score of XGBoost were 0.74, 0.52, and 0.54 respectively.

INTERACTION OF IMPACTING WATER DROP WITH A HEATED SURFACE AND BREAKUP INTO MICRODROPS

Drop impact is important for numerous industrial processes. The recent progress in investigations of drop impact on heated solid surface covers the processes near and above the boiling temperature of the liquid. There is a gap in understanding of drop dynamics for the substrate temperature below the liquid boiling point. We conduct a detailed study of the interaction of the water drop of 10 μl impacting on a heated sapphire plate with a temperature varied within a range of 23–135◦C. Characteristic stages of drop interaction with a substrate at various temperatures are identified, namely impact, spreading, rollback, one liquid column splashing, microdrops detachment, formation, stabilization, breakup, boiling, and evaporation. We show that the spreading time and maximal spreading diameter of the droplet are dominated by inertia and practically independent of the temperature. The influence of the temperature on viscosity dissipation, which limits the maximum spreading diameter, is not significant. However, the temperature rise leads to a considerable decrease of the liquid column contact diameter and to an increase of the liquid column height at the splashing stage. It is revealed that the contact line velocity at the rollback stage depends on temperature. Microdrop detachment from the liquid column is observed for a substrate temperature of 60–100◦C. Beginning from the substrate temperature of 100◦C, the liquid column height is decreased again. The most important observation is the drop breakup into several sessile microdrops just after the spreading for 135◦C, which prevents the rollback and rebound. We show the possible importance of the Marangoni force for thin liquid film breakup and detect the presence of microbubbles, which is also potentially important for breakup.
Hexagonal Boron Nitride/Blue Phosphorene Heterostructure as a Promising Anode Material for Li/Na-Ion Batteries

Blue phosphorene (blue-P), an allotrope of black phosphorene, is prone to oxidize under ambient conditions, which significantly hinders its incorporation in anode for Li/Na ion batteries (LIBs/NIBs). Combining blue-P and hexagonal boron nitride (h-BN) together to construct h-BN/blue-P heterostructure (BN/P) can break the limitation of the restricted properties of blue-P. By means of first-principles computations, we explored the potential of using BN/P as anode material for LIBs/NIBs. Our computations show that the adsorption energies of Li/Na in BN/P are stronger than those in blue-P. Interestingly, although Li has similar chemical properties to Na, their the most energetically favorable sites on BN/P are different. Li prefers to insert into the interlayer of BN/P while Na prefers to absorb on the blue-P surface of BN/P. Furthermore, BN/P can achieve high theoretical specific capacities 801 and 541 mAh/g and low diffusion barriers 0.08 and 0.07 eV for LIBs and NIBs, respectively. All these characteristic.
Enhanced Cycling Stability of Macroporous Bulk Antimony‐Based Sodium‐Ion Battery Anodes Enabled through Active/Inactive Composites

Engineering strategies based on “nanostructuring” and “active/inactive composites” are commonly used separately to improve the performance of alkali‐ion battery electrodes. Here, these two strategies are merged to further enhance the performance of alloy‐type alkali‐ion battery anodes. Specifically, macroporous antimony (Sb)/magnesium fluoride (MgF2) active/inactive composite material is used as a high‐performance Na‐ion battery anode. The porous Sb phase with pore size in the sub‐micrometer range acts as the electrochemically active component and the electrochemically inactive dense MgF2 phase acts as a mechanical buffer. Na‐ion battery anodes made of porous Sb/MgF2 active/inactive composites are reversibly sodiated for over 300 cycles, delivering a capacity of ≈551 mAh g−1 after 300 cycles at a C‐rate of C/2. This performance is remarkable because the porous Sb/MgF2 composite is not made of mesoporous structures. Furthermore, the cycling longevity of this porous Sb/MgF2 composite outperforms the common nanostructured Sb‐based Na‐ion battery anode materials. This good performance is attributed to the “porous active/inactive” configuration, where the dense inactive mechanical buffer phase absorbs part of the phase transformation‐induced stresses, while porosity in the active phase helps to accommodate the phase transformation induced volume expansions and electrolyte transfer into the bulk of this composite.
The Lower Limit of Pitch Perception for Pure Tones and Low-Frequency Complex Sounds

The lower limit of pitch (LLP) perception was explored for pure tones, sinusoidally amplitude-modulated (SAM) tones with a carrier frequency of 125 Hz, and trains of 125-Hz tone pips, using an adaptive procedure to estimate the lowest repetition rate for which a tonal/humming quality was heard. The LLP was similar for the three stimulus types, averaging 19 Hz. There were marked individual differences, which were correlated to some extent across stimulus types. The pure-tone stimuli contained a single resolved harmonic, whereas the SAM tones and tone-pip trains contained only unresolved components, whose frequencies did not necessarily form a harmonic series. The similarity of the LLP across stimulus types suggests that the LLP is determined by the repetition period of the sound for pure tones, and the envelope repetition period for complex stimuli. The results are consistent with the idea that the LLP is determined by a periodicity analysis in the auditory system, and that the longest time interval between waveform or envelope peaks for which this analysis can be performed is approximately 53 ms.
On-Road Object Detection and Tracking Based on Radar and Vision Fusion: A Review

Environment perception, one of the most fundamental and challenging problems of autonomous vehicles (AVs), has been widely studied in recent decades. Due to inferior fault tolerance and the insufficient information caused by a single autonomous sensor (e.g., radar, lidar, or camera), multisensor fusion plays a significant role in environment perception systems, and its performance directly defines the safety of AVs. Due to good performance and low cost, radar-vision (RV) fusion has become popular and widely applied in the mass production of AVs. However, there have been a few generalizations about RV fusion, and in that context, this article presents a comprehensive review on RV fusion for both object detection and object tracking by RV fusion. With respect to the input data and fusion framework, this article categorizes the existing fusion frameworks into two categories, providing a detailed overview of each: object detection and tracking by RV fusion. Also, the state-of-the-art detectors and trackers based on deep learning are introduced, along with an analysis of their advantages and limitations. Finally, challenges and improvements are summarized to facilitate future research in the RV fusion field.
Recherches technologiques sur composés phénoliques des vins rouges II- Les facteurs de dissolution des composés phénoliques

La maceration des parties solides de la grappe (pellicules, pepins et eventuellement rafles) au cours de la fermentation constitue le caractere essentiel de la vinification en rouge qui la differencie de la vinification en blanc. Ce phenomene joue un role fondamental sur les proprietes du vin en lui apportant tous les composes phenoliques indispensables. Les lois de la maceration sont loin d'etre simples. D'une part les conditions de la dissolution de chaque type de composes phenoliques et de leur diffusion dans le mout au cours de la fermentation sont affectees de facon differente par plusieurs facteurs. D'autre part, les phenomenes de maceration ne se limitent pas a une dissolution des constituants des parties solides dans le jus ; il y a egalement, dans certaines conditions, fixation des constituants du mout sur les parties solides.
Preregistration in Complex Contexts: A Preregistration Template for the Application of Cognitive Models

In recent years, open science practices have become increasingly popular in psychology and related sciences. These practices aim to increase rigour and transparency in science as a potential response to the challenges posed by the replication crisis. Many of these reforms -- including the highly influential preregistration -- have been designed for experimental work that tests simple hypotheses with standard statistical analyses, such as assessing whether an experimental manipulation has an effect on a variable of interest. However, psychology is a diverse field of research, and the somewhat narrow focus of the prevalent discussions surrounding and templates for preregistration has led to debates on how appropriate these reforms are for areas of research with more diverse hypotheses and more complex methods of analysis, such as cognitive modelling research within mathematical psychology. Our article attempts to bridge the gap between open science and mathematical psychology, focusing on the type of cognitive modelling that Crüwell, Stefan, & Evans (2019) labelled model application, where researchers apply a cognitive model as a measurement tool to test hypotheses about parameters of the cognitive model. Specifically, we (1) discuss several potential researcher degrees of freedom within model application, (2) provide the first preregistration template for model application, and (3) provide an example of a preregistered model application using our preregistration template. More broadly, we hope that our discussions and proposals constructively advance the debate surrounding preregistration in cognitive modelling, and provide a guide for how preregistration templates may be developed in other diverse or complex research contexts.
Political Social Work: An Essential Component of the Profession

Social workers have played a key role in political settings from the profession's historic roots to present day. Their knowledge, skills and values position social workers to practice in political settings. Social work faculty and students were interviewed to assess a) how field placements in legislative offices and participation in Campaign School and NASW-sponsored Legislative Education and Advocacy Day (LEAD) impacted students’ professional development and perspectives on political social work, and b) social work faculties’ perception of these activities in students’ social work education and necessary political social work knowledge and skills. Initial results demonstrate a high level of support for these activities among faculty and students with opportunities to further include them in the explicit and implicit social work curriculum.
Nb2O5 Nanoparticles Anchored on an N-Doped Graphene Hybrid Anode for a Sodium-Ion Capacitor with High Energy Density

Sodium-ion capacitors (SICs) have gained great interest for mid- to large-scale energy storage applications because of their high energy and high power densities as well as long cycle life and low cost. Herein, a T-Nb2O5 nanoparticles/N-doped graphene hybrid anode (T-Nb2O5/NG) was prepared by solvothermal treating a mixed ethanol solution of graphene oxide (GO), urea, and NbCl5 at 180 °C for 12 h, followed by calcining at 700 °C for 2 h, in which T-Nb2O5 nanoparticles with average size of 17 nm were uniformly anchored on the surface of the nitrogen-doped reduced GO because their growth and aggregation were hindered, and also, the electronic conductivity and the active sites of T-Nb2O5/NG were improved by doping nitrogen. The T-Nb2O5/NG anode showed superior rate capability (68 mA h g–1 even at 2 A g–1) and good cycling life (106 mA h g–1 at 0.2 A g–1 for 200 cycles and 83 mA h g–1 at 1 A g–1 for 1000 cycles) and also showed high-rate pseudocapacitive behavior from kinetics analysis. A novel SIC system had been constructed by using the T-Nb2O5/NG as anode and commercially activated carbon as the cathode; it delivered an energy density of 40.5 W h kg–1 at a power density of 100 W kg–1 and a long-term cycling stability (capacity retention of 63% after 5000 consecutive cycles at a current density of 1 A g–1) and showed a promising application for highly efficient energy storage systems.
Solvation free energy of light alkanes in polar and amphiphilic environments

Computer simulations of molecular models are powerful technique that have improved the under- standing of many biochemical phenomena. The method is frequently applied to study the motions of biological macromolecules such as protein and nucleic acids, which can be useful for interpreting the results of certain biophysical experiments. In this work, we have estimated the solvation free energy for light alkane (methane, ethane, propane and n-butane) dissolved in water and methanol respectively over a broad range of temperatures, from 275 K to 375 K, using molecular dynamics simulations. The alkane (methane, ethane, propane and n-butane), and methanol molecules are described by the OPLS-AA (Optimized Potentials for Liquid Simulations-All Atom) potential, while water is modeled by TIP3P (Transferable Intermolecular Potential with 3-Points) model. We have used the free energy perturbation method (Bennett Acceptance Ratio (BAR) method) for the calculation of free energy of solvation. The estimated values of solvation free energy of alkane in the corresponding solvents agree well with the available experimental data.BIBECHANA 16 (2019) 91-104
Brief Report

This trend study analyzed 9 years (2011–2019) of cross-sectional survey responses to Klein’s Sexual Orientation Grid to explore changes in sexual orientation among emerging adult college students. Categorical regression models based on ordinal responses revealed that participants were moving away from exclusive heterosexuality on attraction, behavior, and identity subscales at a rate of approximately 6% per year. This trend augments for women after 2014, coinciding with increased advocacy efforts related to U.S. marriage equality, but attenuates for men. Participants’ race also related to variations in sexual orientation: Black participants were less likely than White participants to identify as exclusively heterosexual, whereas the pattern reversed for Asian participants relative to White participants. These findings suggest that changes in sexual orientation are occurring among emerging adults in the United States, potentially in response to changing social and political contexts, but these changes are more pronounced in women and Black emerging adults.
Preparation, Characterization and Anti-Bacterial Activity of Zinc Oxide-Gelatin Nanocomposite Film for Food Packaging Applications

Gelatin based composite films were prepared using various crosslinking agents for possible application in the food packaging industry. In the present study, gelatin films were formed by the incorporation of zinc oxide (ZnO) nanoparticles. The ZnO nanoparticles were synthesized by a wet chemical method using zinc nitrate as precursor and starch as stabilizing agent. It was characterized by FTIR. Surface morphology and thermal studies were performed by SEM and TGA respectively. The average particle size was calculated from the X-ray diffraction pattern using Scherrer's equation. Mechanical studies were done with a Universal Testing Machine. The distribution of particles was clearly seen by SEM and thermal studies showed that the decomposition temperature of gelatin was increases by the incorporation nano ZnO. The mechanical properties were also improved with increase in concentration of nano ZnO. Antibacterial activities of the films were also studied against S. aureus, V. cholera and E. coli by the disc diffusion method.
Electrochemical Measurements of Salivary Alpha-Amylase Activity

Stress constitutes a more and more common cause for many health disorders in modern society. Salivary α-amylase (AA), the most abundant enzyme in human whole saliva, has in recent years been found to be a good surrogate biomarker for monitoring stress levels in individuals. This work aims to form the foundation of a novel approach for measuring the activity of the enzyme in saliva samples by means of electrochemistry. The idea is to implement several enzymes along with a starch substrate and an electron mediator in a single system. This system is then to be coated onto a screen-printed electrode (SPE), which is used along with an electrical component, designed to give rise to a quantifiable, electrical signal when the starch is broken down by the AA contained in an added saliva sample. Several such enzyme systems are here qualitatively evaluated. As electron mediator, ferro-/ferricyanide is used. Two different enzymes, glucose oxidase (GOx) and pyrroloquinoline quinone dependent glucose dehydrogenase (PQQ-GDH), are tested for making up the saccharide oxidising part of the system. Both prove themselves capable in terms of qualitatively giving rise to an electrical signal. But, in terms of internal quantitative comparisons between the two, no practical experiments are performed in this work. In some runs, the enzyme α-glucosidase (AG) is used as an intermediate for breaking down the AA/starch oligosaccharide products into monosaccharides. This to increase the system’s electrical signal output when using GOx as oxidising agent. Regrettably, due to lack of AG enzyme, these runs do not provide any conclusive data, and so further investigations of systems including this enzyme are needed. Otherwise, all systems tested seem to work, and neither of them appear better than the others. Therefore, all of them will require further quantitative testing to determine which one is best to implement in the final design of the enzyme system to be applied onto the SPE.
$D_s^+ \to \phi \rho^+$ Decay

Motivated by the experimental measurement of the decay rate, $\Gamma$, and the longitudinal polarization, $P_L$, in the Cabibbo favored decay $D_s^+\to \phi {\rho}^{+}$, we have studied theoretical prediction within the context of factorization approximation invoking several form factors models. We were able to obtain agreement with experiment for both $\Gamma$ and $P_L$ by using experimentally measured values of the form factors $A_1^{D_s\phi}(0)$, $A_2^{D_s\phi}(0)$ and $V^{D_s\phi}(0)$ in the semi-leptonic decay $D_s^+\to \phi l^{+}\nu_{l}$. We have also included in our calculation the effect of the final state interaction ($fsi$) by working with the partial waves amplitudes $S$, $P$ and $D$. Numerical calculation shows that the decay amplitude is dominated by $S$ wave, and that the polarization is sensitive to the interference between $S$ and $D$ waves. The range of the phase difference $\delta_{SD} = \delta_S - \delta_D$ accommodated by experimental error in $P_L$ is large.
