Dzyaloshinskii-Moriya Interactions of Skyrmions for Memory and Logic Devices

A skyrmion is considered to be a swirling quasi-particle that can exhibit nano-size disturbances similar to those by a knot of twisting magnetic field lines. The "tangles" observed in the magnetic field lines usually generate very strong localized magnetic fields. Thus, a stable skyrmion represent the smallest realizable ideal element with a magnetic texture while an antiskyrmion is considered to be a localized magnetic particle that represents a non-trivial magnetization texture with a specified magnitude with opposite topological charge to that of a skyrmion. The demand for novel memory and logic devices has grown in recent days with the advancement of communication and information technology. Particular attention has been drawn to the use of skyrmions and antiskyrmions in memory access and storage. The findings in most recent laboratory observation at room temperature further encourage more studies mainly covering transport and dynamic properties of both skyrmions and antiskyrmions. So far, some investigations have pointed on skyrmions for reservoir computing applications which in most applications require very large memory storages and fast access capabilities. To attain this scientific dream, a very careful ferromagnetic material re-engineering on the possibility of annihilating a skyrmion by an antiskyrmion (pairwise) to develop new concepts that may be useful for memory and logic applications. It is only recently that material physicists proposed skyrmions for ultra-dense magnetic memories though it has not been implemented. In this paper, we present the model, simulation and discuss the findings obtained by simulating a magnetic skyrmion model. These magnetic skyrmions were stabilized by Dzyaloshinskii-Moriya interaction. They were analyzed as tiny whirls of magnetic configurations that exhibit memory or logic element characteristics depending on complexity of their logical element geometry. The findings suggested that a magnetic skyrmion with antiskyrmion has a capacity to act as memory element. As a result, adopting them for memory applications can simplify the fabrication process of logic elements if their magnetic spin textures are taken into account. These findings form a promising pointer for future application of skyrmion and antiskyrmion for memory, logic and reservoir computing applications.
A fast multipole method combined with a reaction field for long-range electrostatics in molecular dynamics simulations: The effects of truncation on the properties of water

We present a combination of the structure adapted multipole method with a reaction field (RF) correction for the efficient evaluation of electrostatic interactions in molecular dynamics simulations under periodic boundary conditions. The algorithm switches from an explicit electrostatics evaluation to a continuum description at the maximal distance that is consistent with the minimum image convention, and, thus, avoids the use of a periodic electrostatic potential. A physically motivated switching function enables charge clusters interacting with a given charge to smoothly move into the solvent continuum by passing through the spherical dielectric boundary surrounding this charge. This transition is complete as soon as the cluster has reached the so-called truncation radius Rc. The algorithm is used to examine the dependence of thermodynamic properties and correlation functions on Rc in the three point transferable intermolecular potential water model. Our test simulations on pure liquid water used either.
Observations of Mantle Seismic Anisotropy Using Array Techniques: Shear‐Wave Splitting of Beamformed SmKS Phases

Shear‐wave splitting measurements are commonly used to resolve seismic anisotropy in both the upper and lowermost mantle. Typically, such techniques are applied to SmKS phases that have reflected (m‐1) times off the underside of the core‐mantle boundary before being recorded. Practical constraints for shear‐wave splitting studies include the limited number of suitable phases as well as the large fraction of available data discarded because of poor signal‐to‐noise ratios (SNRs) or large measurement uncertainties. Array techniques such as beamforming are commonly used in observational seismology to enhance SNRs, but have not been applied before to improve SmKS signal strength and coherency for shear wave splitting studies. Here, we investigate how a beamforming methodology, based on slowness and backazimuth vespagrams to determine the most coherent incoming wave direction, can improve shear‐wave splitting measurement confidence intervals. Through the analysis of real and synthetic seismograms, we show that (a) the splitting measurements obtained from the beamformed seismograms (beams) reflect an average of the single‐station splitting parameters that contribute to the beam; (b) the beams have (on average) more than twice as large SNRs than the single‐station seismograms that contribute to the beam; (c) the increased SNRs allow the reliable measurement of shear wave splitting parameters from beams down to average single‐station SNRs of 1.3. Beamforming may thus be helpful to more reliably measure splitting due to upper mantle anisotropy. Moreover, we show that beamforming holds potential to greatly improve detection of lowermost mantle anisotropy by demonstrating differential SKS–SKKS splitting analysis using beamformed USArray data.
Effect of Wax Additives and Silanization of Diatom Surfaces on Thermomechanical Properties of Polylactide Composites

In the present study, tests were conducted on high-filled composite samples on a polylactide matrix, modified with diatomaceous earth, three types of silanes, and natural and synthetic wax. The obtained samples were characterized in terms of the effect of modifications on mechanical properties (tensile strength, flexural strength, and impact resistance) or processing properties, e.g., melt flow rate (MFR). The study showed that the modification had a favorable effect on the processing properties of the composites, associated with up to an eight-fold increase in flow rate index compared with the reference sample, especially for samples treated with methyltrimethoxysilane (MTMOS), and up to a ten-fold increase under low shear-rate flow conditions. The effect of the addition of waxes of different origins (synthetic and natural) was also determined, and it was shown that beeswax tended to reduce the flow rate of the composites regardless of the silane used. The addition of synthetic wax to composites increased the tendency to agglomerate diatomaceous earth, while natural wax had a positive effect on filler dispersion.

Background: Maternal with to COVID-19 is a new maternal emergency issue leading to maternal morbidity and mortality. In Indonesia, the number of cases of maternal mortality with COVID-19 began to increase. This study aims to determine the characteristic of maternal deaths due to COVID-19 in a tertiary care center in Indonesia.Method: This observational-retrospective study descriptively analyzed 15 maternal deaths due to COVID-19 admitted to the Department of Obstetrics and Gynaecology at the tertiary care teaching hospital from March to December 2020. We included suspect, probable, and confirmed COVID-19 in the samples. Therefore, the total sampling was recorded and analyzed descriptively by Microsoft Excel.Results: There are fifteen maternal deaths from 429 maternal cases with COVID-19 in our hospital. The majority ages were in the age group 19-35 years (73.33%); body mass index (BMI) 25-29.9 (33.33%); five days average length of stay; one comorbidity (53.33%); and multiple comorbidities (20.00%). The case fatality rate (CFR) of maternal death due to COVID-19 is 3.49% were profiled out this study. The most cause of death was acute respiratory distress syndrome (ARDS) (53.33%). Conclusions: Most common characteristics of the object of this study were the age between 19-35 years, comorbidity, obesity, upper respiratory tract symptoms, elevated D-dimer, and the complication of ARDS, which are the risk factors of the deaths.
Conjugation and the prime decomposition of knots in closed, oriented 3-manifolds

In this paper we consider the prime decomposition of knots in closed, oriented 3-manifolds. (For classical knots one can easily prove the uniqueness of prime decomposition by using a standard innermost disk argu-ment.) We define a new relation, conjugation, between oriented knots in closed, oriented 3-manifolds and prove the following results. ( 1 ) The prime decomposition is, roughly speaking, uniquely determined up to conjugation, (2) there is a prime knot á? in SlxS2 suchthat âl#3? \ = 3¡#X2 if ^¡ is a conjugation of ^2 ) and (3) if a knot 3? has a prime decomposition which does not contain 31, then it is the unique prime decomposition of X .
In Vitro and In Silico Evaluation of the Antimicrobial and Antioxidant Potential of Thymus pulegioides Essential Oil

The study was designed to analyze and evaluate the antioxidant and antibacterial properties of the essential oils of Thymus pulegioides L. grown in Western Romania. Thymus pulegioides L. essential oil (TPEO) was extracted by steam distillation (0.71% v/w) using a Craveiro-type apparatus. GC-MS investigation of the TPEO identified 39 different compounds, representing 98.46% of total oil. Findings revealed that thymol (22.89%) is the main compound of TPEO, followed by para-cymene (14.57%), thymol methyl ether (11.19%), isothymol methyl ether (10.45%), and beta-bisabolene (9.53%). The oil exhibits good antibacterial effects; C. parapsilosis, C. albicans, S. pyogenes, and S. aureus were the most sensitive strains. The antioxidant activity of TPEO was evaluated by peroxide and thiobarbituric acid value, 1,1-diphenyl-2-picrylhydrazyl radical (DPPH), [2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium] (ABTS) radical scavenging assay, and beta-carotene/linoleic acid bleaching testing. The antioxidative data recorded reveal, for the first time, that TPEO inhibits primary and secondary oxidation products, in some particular conditions, better than butylated hydroxyanisole (BHA) with significant statistical difference (p < 0.05). Moreover, TPEO antioxidant capabilities in DPPH and ABTS assays outperformed alpha-tocopherol (p < 0.001) and delta-tocopherol (p < 0.001). Molecular docking analysis revealed that one potential target correlated with the TPEO antimicrobial activity was d-alanine-d-alanine ligase (DDl). The best scoring ligand, linalyl anthranilate, shared highly similar binding patterns with the DDl native inhibitor. Furthermore, molecular docking analysis also showed that the main constituents of TPEO are good candidates for xanthine oxidase and lipoxygenase inhibition, making the essential oil a valuable source for protein-targeted antioxidant compounds. Consequently, TPEO may represent a new potential source of antioxidant and antibacterial agents with applicability in the food and pharmaceutic industries.
Tropical Cyclone Intensity in Vertical Wind Shear

Abstract The structure and intensity changes of tropical cyclones (TCs) in environmental vertical wind shear (VWS) are investigated in this study using the fifth-generation Pennsylvania State University–National Center for Atmospheric Research (PSU–NCAR) Mesoscale Model (MM5). Triply nested domains of 36-, 12-, and 4-km resolution are used with fully explicit moisture physics in the 4-km domain. Idealized environments with easterly shears of 2, 4, 6, 8, and 10 m s−1 between 800 and 200 hPa are applied on an f plane. Under small values of VWS (2 and 4 m s−1), the TC intensities are similar to that of the control (CTRL; i.e., no VWS) after initial adjustments. The TCs under 6 and 8 m s−1 of VWS are not as intense, although they do not weaken during the simulation. On the other hand, the TC in 10 m s−1 of VWS weakened significantly. Given the same VWS, the TC intensity is also found to be sensitive to TC size. Experiments with TCs with a smaller radius of 15 m s−1 wind reveal that while the TC in 2 m s−1 of .
On the global uniform stability analysis of non-autonomous dynamical systems: A survey

In this survey, we introduce the notion of stability of time varying nonlinear systems. In particular we investigate the notion of global practical exponential stability for non-autonomous systems. The proposed approach for stability analysis is based on the determination of the bounds of perturbations that characterize the asymptotic convergence of the solutions to a closed ball centered at the origin.
Postoperative opioid‐prescribing practices in otolaryngology: Evidence‐based guideline outcomes

We previously reported that >50% of postoperative opioids prescribed at our institution went unused for common otolaryngologic procedures. Based on these findings, we instituted multimodal, evidence‐based guidelines for postoperative pain management. In the second part of our multiphasic study, we evaluated the effects of these guidelines on (1) quantity of unused opioids, (2) patient satisfaction, and (3) institutional perceptions toward the opioid epidemic and prescribing guidelines.
Exposure to Endocrine Disruptors (Di(2-Ethylhexyl)phthalate (DEHP) and Bisphenol A (BPA)) in Women from Different Residing Areas in Italy: Data from the LIFE PERSUADED Project

Phthalates and bisphenol A (BPA) are plasticizers used in many industrial products that can act as endocrine disruptors and lead to metabolic diseases. During the LIFE PERSUADED project, we measured the urinary concentrations of BPA and Di(2-ethylhexyl)phthalate (DEHP) metabolites in 900 Italian women representative of the Italian female adult population (living in the north, centre, and south of Italy in both rural and urban areas). The whole cohort was exposed to DEHP and BPA with measurable levels above limit of detection in more than 99% and 95% of the samples, respectively. The exposure patterns differed for the two chemicals in the three macro-areas with the highest urinary levels for DEHP in south compared to central and northern Italy and for BPA in northern compared to central and southern Italy. BPA levels were higher in women living in urban areas, whereas no difference between areas was observed for DEHP. The estimated daily intake of BPA was 0.11 μg/kg per day, about 36-fold below the current temporary tolerable daily intake of 4 μg/kg per day established by the EFSA in 2015. The analysis of cumulative exposure showed a positive correlation between DEHP and BPA. Further, the reduction of exposure to DEHP and BPA, through specific legislative measures, is necessary to limit the harmfulness of these substances.
Mode dynamics in nonuniform waveguide arrays: a graph Laplacian approach

Light propagation in nonlinear waveguide arrays displays rich phenomena with multiple applications. Technological advances present opportunities to study distinct dynamical features for a wide range of one-dimensional and two-dimensional arrays. The traditional research on arrays considers the individual elements to be identical. Here we study coupled arrays of non-identical waveguides in geometries that account for nonuniform coupling strengths. The model is now a generalized nonlinear Schrödinger equation where the usual Laplacian is replaced by the graph Laplacian. We show that since this matrix is symmetric, the dynamics is naturally described using its eigenvectors as a basis. When the eigenvalues are all distinct, we show that there is no resonant transfer of energy between the different eigenmodes. We illustrate this on a simple graph.
The Relationship Between Prognosis and Red Cell Distribution Width (RDW) and RDW-Albumin Ratio (RAR) in Patients with Severe COVID-19 Disease

Purpose The present study aimed to investigate the relationship between prognosis and the red cell distribution width (RDW) and the RDW-albumin ratio (RAR) in patients with coronavirus diseases 2019 (COVID-19), since serum albumin and RDW levels may reflect inflammatory conditions. Patients and Methods A total of 289 patients who had been diagnosed with severe COVID-19 in the emergency department were retrospectively analyzed. The RAR levels were calculated by dividing RDW-CV by albumin. Patient groups (survivors, dying patients, those who received mechanical ventilation (MV) support or not, and those who needed vasopressors or not) were compared with regard to RDW-SD, RDW-CV and the RAR levels. Results RDW-SD, RDW-CV and the RAR levels were found to be statistically significantly higher in patients who died, and who received MV and vasopressor support, compared to those who survived and did not receive support (p<0.001 for all). In addition, while the cut-off value of RAR was >5.43, the sensitivity was 91.6%, the specificity was 93.7%, NPV was 93.1% and the AUC was 0.965 in predicting mortality (p<0.001). Logistic regression analysis showed that RDW-SD and RAR were independent risk factors for mortality in patients with severe COVID-19. Conclusion Elevated RDW and RAR levels at the time of admission may independently predict mortality and the need for vasopressor or MV support.
No survival benefit in never‐smoker never‐drinker patients with oral cavity cancer

Although strongly associated with tobacco and alcohol use, many oral cavity squamous cell carcinoma (OCSCC) cases occur in patients without exposure to either, known as “never‐smoker, never‐drinkers” (NSND). We aimed to compare clinical outcomes between NSND and tobacco/alcohol‐exposed populations and to define demographic characteristics of NSND.
Quantum noise in optical tweezers

Quantum enhanced sensitivity in optical tweezers based particle tracking was recently demonstrated. This has provided the necessary tool for quantum metrology to play an important role in biological measurements. Here we introduce the basic theory relevant to such optical tweezers experiments, and overview the significance of sub-shot noise limited sensitivity to practical experiments. In particular, biophysical experiments are subject to optical power constraints, which therefore limits the absolute sensitivity which is classically achievable. Quantum enhanced particle tracking can overcome this limit, and is therefore likely to play an important role in such biophysical experiments in the near future.
COVID-19 and Vaccine Hesitancy: Could Health Literacy be the Solution?

Objective: Practices such as the use of masks, cleaning measures, and social distancing have come to the fore to prevent the Coronavirus disease-2019 (COVID-19) pandemic. In addition to this, the most important way to fight the pandemic seems to be vaccination. However, "vaccine hesitancy" is seen as an important obstacle to attempts to control the pandemic. With this study, we aimed to evaluate the effects of having inadequate or incorrect information, one of the possible determinants of attitudes towards the COVID-19 vaccine. Methods: The data of this descriptive study were collected via an online questionnaire from patients (N=496) involving Sociodemographic Data Form, Turkey Health Literacy Scale-32 and Anti-Vaccine Scale. Results: The data revealed that 7.5% of the participants would not be vaccinated and 14.3% were indecisive. We found a negative correlation between vaccine refusal and health literacy, thus confirming the main hypothesis of our study. Also, an increase in education years was a negative predictor of vaccine hesitation. Conclusion: Currently, the most important approach in fighting the pandemic is the vaccination of society. Having the right information is extremely important to fight vaccine refusal attitudes. The fight against vaccination requires joint efforts from governments and media resources, including social media. (English) [ FROM AUTHOR]
The Symmetric Eigenvalue Problem

According to Parlett, 'Vibrations are everywhere, and so too are the eigenvalues associated with them. As mathematical models invade more and more disciplines, we can anticipate a demand for eigenvalue calculations in an ever richer variety of contexts. ' Anyone who performs these calculations will welcome the reprinting of Parlett's book (originally published in 1980). In this unabridged, amended version, Parlett covers aspects of the problem that are not easily found elsewhere. The chapter titles convey the scope of the material succinctly. The aim of the book is to present mathematical knowledge that is needed in order to understand the art of computing eigenvalues of real symmetric matrices, either all of them or only a few. The author explains why the selected information really matters and he is not shy about making judgments. The commentary is lively but the proofs are terse.
Experimental method to detect phase transitions via the chemical potential

We propose an experimental method to confirm theoretical predictions concerning the detection of phase transitions in solids via the measurement of the chemical potential as a function of temperature. Here, as experimental evidence of the validity of these predictions, we perform indirect measurements of the chemical potential vs temperature for Gd, Cr, and TiNi samples by means of an electrochemical experiment. This made it possible to easily localize all critical temperatures connected either with magnetic phase transitions $[{T}_{\mathrm{C}}$ (Gd), ${T}_{\mathrm{N}}$ (Cr)] or structural phase transformations in the shape-memory alloy NiTi. The values of the critical temperatures, obtained in this way remain in exceptionally good agreement with the results of the auxiliary heat flow measurements and the existing literature data concerning critical temperatures. We hope that further development of the experimental techniques, based on chemical potential measurements, can provide a new experimental tool in the search for phase transitions (induced by temperature, pressure, concentration, etc.) in real materials, regardless of the type of phase transitions and irrespective of the underlying mechanism.
