Role of adding carbon nanotubes in the electric and electromagnetic shielding behaviors of three different types of graphene in hybrid nanocomposites

Graphene-related materials (GRM) are promising materials to improve mechanical, electrical, and optical polymer properties. Adding multi-wall carbon nanotubes (MWCNT) on GRM nanocomposites promotes synergistic effects on its electrical properties and electromagnetic interference shielding effectiveness (EMI SE). This study focused on evaluating the addition of MWCNT on three different polycarbonate (PC)/acrylonitrile butadiene styrene (ABS)/GRM nanocomposites. These hybrid nanocomposites were prepared by melt mixing using extrusion and injection-mold processes. The morphologies of the nanocomposites were evaluated by field emission gun scanning electron microscopy (FEG-SEM), and their proprieties were characterized by X-ray diffraction (XRD), oscillatory rheological, dielectric spectroscopy, and EMI SE analyses. The electrical behavior of all hybrid nanocomposites was anisotropic due to the injection-molded preparation process. The lateral size, thickness, and production method of the GRM were indicated to be critical factors for the electrical and EMI SE behaviors of these composites. The nanocomposites with GRM2, which had the smallest lateral size and thickness (graphene nanoplatelets), promoted total attenuation levels around 20 dB with 1.5 wt% of MWCNT, matching the EMI SE required for some commercial applications. Graphical Abstract
Gradient-Guided Single Image Super-Resolution Based on Joint Trilateral Feature Filtering

The state of the arts (SOTAs) of single image super-resolution always exploit guidance from gradient prior. The fusion of gradient guidance is implemented by channel-wise concatenation followed by a convolutional layer. However, the kernels sharing in spatial positions cannot adaptively tune the effect of gradient guidance for all feature positions. To resolve this problem, a novel network module is proposed to simulate the traditional Joint Trilateral Filter (JTF) by extending the definition domain from pixels to features. Moreover, to improve the efficiency and flexibility, the functions of JTF kernel generation for image features and gradient features are explicitly learned instead of individual kernel weights, e.g., the exponential functions in the traditional JTF. Based on the proposed JTF modules, this paper follows the gradient-guided framework which simultaneously infers high-resolution (HR) image features and HR gradient features within two parallel branches, respectively. Specifically, by treating image features and gradient features as cross guidance to each other, the proposed JTF modules adaptively adjust the fusion patterns for local features via a bi-directional way. By doing so, the quality of image features and gradient features is alternatively enhanced. Compared with SOTAs, the proposed JTF-SISR shows improvement which is evaluated for multiple upsampling scales and degradation modes on 5 synthetic datasets, i.e., Set5, Set14, B100, Urban100 and Manga109, and 1 real dataset, i.e., RealSRSet. The code is public in https://github.com/a239xjc/JTF-SISR.

Recent Advances in Silver Nanostructured Substrates for Plasmonic Sensors

Noble metal nanostructures are known to confine photon energies to their dimensions with resonant oscillations of their conduction electrons, leading to the ultrahigh enhancement of electromagnetic fields in numerous spectroscopic methods. Of all the possible plasmonic nanomaterials, silver offers the most intriguing properties, such as best field enhancements and tunable resonances in visible-to-near infrared regions. This review highlights the recent developments in silver nanostructured substrates for plasmonic sensing with the main emphasis on surface plasmon resonance (SPR) and surface-enhanced Raman spectroscopy (SERS) over the past decade. The main focus is on the synthesis of silver nanostructured substrates via physical vapor deposition and chemical synthesis routes and their applications in each sensing regime. A comprehensive review of recent literature on various possible silver nanostructures prepared through these methodologies is discussed and critically reviewed for various planar and optical fiber-based substrates.
Active coping style and pharmacist's burnout during pandemic COVID-19

The aim of these study are to determine the effect of active coping style on pharmacist's burnout and whether the core self-evaluation as a personal resource has a role as a mediator between active coping style and pharmacist's burnout. The pharmacists work so hard to look for the antidote for the virus, so they have to work in shifts to meet the demand for medications, which sometimes cause them to experience burnout. Therefore, the pharmacist needs an active strategies and stable behaviors to deal and solve the problems, known as active coping style. Data were collected from 281 pharmaceutical industry using Core Self-Evaluation Scale by Judge, et. al., Simplified Coping Style Questionnaire by Xie, and Maslach Burnout Inventory-General Survey by Maslach. The data was analyzed using simple mediation regression model no. 4 PROCESS v4.0 by Hayes. The results show core self-evaluation is an effective mediator for the relationship between active coping styles and burnout. The result also indicated that self-esteem has the strongest relationship with and emotional exhaustion. This study highlight active coping style and core self-evaluation are essential for workers in the pharmaceutical industry to overcome their burnout.
The Shapley Value in Minimum Cost Spanning Tree Problems

We associate to each minimum cost spanning tree problem a characteristic function v+ where v+ (S) denotes the cost of connecting agents in S to the source assuming that agents of N n S are already connected. We define the rule as the Shapley value of the game v+: We prove that coincides with a rule present in the literature under different names. We also present a new characterization of this rule using a property of equal contributions.
In Situ Nano-Indentation of a Gold Sub-Micrometric Particle Imaged by Multi-Wavelength Bragg Coherent X-ray Diffraction

The microstructure of a sub-micrometric gold crystal during nanoindentation is visualized by in situ multi-wavelength Bragg coherent X-ray diffraction imaging. The gold crystal is indented using a custom-built atomic force microscope. A band of deformation attributed to a shear band oriented along the (221) lattice plane is nucleated at the lower left corner of the crystal and propagates towards the crystal center with increasing applied mechanical load. After complete unloading, an almost strain-free and defect-free crystal is left behind, demonstrating a pseudo-elastic behavior that can only be studied by in situ imaging while it is invisible to ex situ examinations. The recovery is probably associated with reversible dislocations nucleation/annihilation at the side surface of the particle and at the particle-substrate interface, a behavior that has been predicted by atomistic simulations. The full recovery of the particle upon unloading sheds new light on extraordinary mechanical properties of metal nanoparticles obtained by solid-state dewetting.
Syntax and object types contribute in different ways to bilinguals’ comprehension of spatial descriptions

Abstract The world’s languages draw on different reference frames to encode spatial relationships between people, objects or places. We address how subtle differences in reference frame preferences across Spanish and English affect Spanish–English bilinguals’ interpretations of spatial descriptions involving the terms left and right. Bilinguals saw an entity (‘object’; e.g., a vase or a human) with a circle on either side, along with a description of the location of a ball relative to the object (e.g., The ball is to the right of the vase or The ball is on the vase’s right). Their task was to decide which circle indicated the ball’s location. Results showed that syntax and object type contributed differently to bilinguals’ responses: Effects of syntax patterned with Spanish preferences, whereas effects of object type patterned with English preferences. English language exposure subtly affected bilinguals’ response choices. Results are discussed with respect to experience-based theories of language processing.
Predicting the Weathering Time by the Empty Puparium of Sarcophaga peregrina (Diptera: Sarcophagidae) with the ANN Models

Simple Summary The weathering time of cuticular hydrocarbons from the puparium could assist in estimating the postmortem interval (PMI) of decomposed corpses. However, the composition of cuticular hydrocarbons in the puparium is complicated and has not been well studied for sarcophagid species. Therefore, we examined the compounds of Sarcophaga peregrina (Robineau-Desvoidy, 1830) at varying temperatures and used various machine learning models to predict the weathering time. The artificial neural network (ANN) model may be optimal for weathering time estimation. Abstract Empty puparium are frequently collected at crime scenes and may provide valuable evidence in cases with a long postmortem interval (PMI). Here, we collected the puparium of Sarcophaga peregrina (Diptera: Sarcophagidae) (Robineau-Desvoidy, 1830) for 120 days at three temperatures (10 °C, 25 °C, and 40 °C) with the aim to estimate the weathering time of empty puparium. The CHC profiles were analyzed by gas chromatography-mass spectrometry (GC-MS). The partial least squares (PLS), support vector regression (SVR), and artificial neural network (ANN) models were used to estimate the weathering time. This identified 49 CHCs with a carbon chain length between 10 and 33 in empty puparium. The three models demonstrate that the variation tendency of hydrocarbon could be used to estimate the weathering time, while the ANN models show the best predictive ability among these three models. This work indicated that puparial hydrocarbon weathering has certain regularity with weathering time and can gain insight into estimating PMI in forensic investigations.
Decrease in Tear Film Lipid Layer Thickness in Patients with Keratoconus

Keratoconus (KC) is a progressive corneal disorder characterized by thinning and protrusion, mostly of the inferotemporal and central corneal regions. Dysfunction of the meibomian gland, the excretions of which form the lipid layer of the tear film, has been reported to be associated with KC. Thus, this manuscript investigates the correlation among lipid layer thickness (LLT), partial blink rate (PBR), and KC of different degrees. This retrospective study included 54 patients and 24 healthy controls. The anterior corneal curvature, LLT, and PBR were taken from the unilateral eye of all 78 participants. The difference in those ocular parameters between the moderate and severe groups and the control group is significant. No significant association was found between anterior corneal curvature and LLT (r = −0.2, p = 0.15) across all the patients. However, there was a significant negative correlation between anterior corneal curvature and LLT in moderate (r = −0.6, p < 0.05) and severe (r = −0.7, p < 0.05) keratoconus cases. The results also show a significant negative correlation between anterior corneal curvature and PBR (r = −0.41, p < 0.05). Therefore, we conclude that the severity of keratoconus is associated with the thinning of LLT and the reduction of PBR. This may relate to a further epithelial abnormality with the reduced protection of tear film from the air, leading to the release of proteolytic enzymes that degrade stromal collagen and weaken the cornea.
PERCEPTION OF ESSENCE OF CONTROLLING AND ITS USE IN MANUFACTURING ENTERPRISES IN TIME OF CRISIS: DOES CONTROLLING FULFILL ITS ESSENCE?

The use of controlling in the business sphere is relatively broad and its essence can be perceived diversely by enterprises of different sectors and sizes. The aim of the research is to identify the current state of the use of controlling in Slovak manufacturing enterprises with an assessment of the perception of its essence in terms of capital structure and business performance measured by the Return on Sales (ROS). Total of 347 enterprises were asked by means of stratified sampling in 2020. Goodness-of-fit test was used when examining the representativeness of the research sample and for individual hypotheses the two-sample test of relative frequencies, relative frequency test, 95% interval estimates of relative frequencies, contingency and Pearson’s chi-square test were applied. Testing confirmed the existence of statistically significant correlation between the capital structure of manufacturing enterprises and the level of wider perception and practical use of the essence of controlling in relation to the performance measured by ROS. In conclusion is demonstrated that the potential of controlling in enterprises is not fully used, especially in the form of comprehensive secondary coordination of management and the possible directions of using it are outlined, with a positive impact on business performance.
Design of Remote Monitoring System for Lithium Battery Operating Statu

The safety of lithium batteries has always been an important problem that restricts the rapid development of lithium batteries. In view of the problems such as the untimely and difficult monitoring of the thermal runaway behavior of the lithium battery energy storage system, a remote monitoring system for the operating state of lithium batteries based on ZigBee and NB-IOT technology is designed. The real-time collection of the operating parameters of lithium batteries is realized through various sensors, the whole system is constructed by the Internet of things technology, and the uploading of operating parameters is realized through the network. It is verified that the system can operate stably, collect the operating parameters of lithium battery and upload relevant data in real time, facilitate the remote monitoring of staff, and provide a strong guarantee for the safety of lithium battery energy storage system.
Theorie und Anwendungen Hierarchischer Matrizen

The modeling of physical properties often leads to the task of solving partial differential equations or integral equations. The results of some discretisation and linearisation process are matrix equations or linear systems of equations with special features. In the case of partial differential equations one exploits the local character of the differentiation by using some finite element method or finite difference scheme and gains a sparse system matrix. In the case of (nonlocal) integral operators low rank approximations seem to be the method of choice. These are either given explicitly by some multipole method or panel clustering technique or implicitly by rank revealing decompositions. Both types of matrices can be represented as so-called H-matrices. In this thesis we investigate algorithms that perform the addition, multiplication and inversion of H-matrices approximately. Under moderate assumptions the complexity of these new arithmetics is almost linear (linear up to logarithmic terms of order 1 to 3). The arithmetic operations can be performed adaptively, that is up to some given accuracy epsilon the relative error of the operations is zero. The question arises under which circumstances the inverse of an H-matrix can be approximated by an H-matrix. For the techniques used in this thesis we need very restrictive assumptions, but the numerical examples in the last part indicate that the approximability does not depend on these assumptions.
Discriminating Benign and Malignant Brain Tumors By Spectral Analysis of Cerebrospinal Fluid

The preliminary study is concerned with an innovative technique for the discrimination of malignant brain tumor from benign with reasonable sensitivity and specificity. The entire study is based on the relative fluorescence intensity and life-time of bio-fluorophores like tryptophan and tyrosine which are then validated as a set of ratio parameters. Resultantly, it was seen that malignancy was characterized by three-fold enhancement of tyrosine. The picosecond-time resolved decay time measurement was done, which exhibited two-fold decrease in decay time for malignant sample. The improved accessibility, with minimal invasiveness to the patient, and lower cost are encouraging aspects of this technique.
Search for supersymmetry at the CMS in all-hadronic final state

We present a search for supersymmetry (SUSY) in the fully hadronic final state with the CMS detector at the LHC. This final state contains at least two jets and a significant transverse energy imbalance due to neutralinos escaping detection. The background to all-hadronic signature arise from QCD multijet production, ttbar and electroweak boson+jet production. These background can be estimated by utilizing a data-driven approach using events thus enabling a possible discovery of SUSY in the early physics data. In addition to the generic search, we also present an analysis which utilizes a new quantity, alpha_T, constructed exclusively from the transverse energies of the jets to effectively eliminate the QCD background.
D-Band Waveguide Diplexer Fabricated Using Micro Laser Sintering

We report a $D$ -band waveguide diplexer, with two passbands of 130–134 and 151.5–155.5 GHz, fabricated using micro laser sintering (MLS) additive manufacturing with stainless steel. This is the first demonstration of metal 3-D printing technology for multiport filtering devices at a sub-terahertz (THz) frequency. For comparison, the same diplexer design has also been implemented using computer numerical controlled (CNC) milling. The diplexer, designed using coupling matrix theory, employs an all-resonator and $E$ -plane split-block structure. The two channels are folded for compactness. A staircase coupled structure is used in one channel to increase the isolation performance. The printed waveguide flanges are modified to adapt to the limited printing volume from the MLS. Effects of fabrication tolerance on the diplexer are investigated. An effective and unconventional electroless plating process is developed. The measured average insertion losses of the gold-coated diplexer are 1.31 and 1.37 dB, respectively. The respective frequency shifts from design values are 0.92% and 1.1%, and bandwidth variations are 4% and 15%. From a comprehensive treatment of the end-to-end manufacturing process, the work demonstrates MLS to be a promising fabrication technique for complex waveguide devices at a sub-THz frequency range.
The Utility of Capsicum annuum L. in Internal Medicine and In Dentistry: A Comprehensive Review

Capsaicin is a chili peppers extract, genus Capsicum, commonly used as a food spice. Since ancient times, Capsaicin has been used as a “homeopathic remedy” for treating a wild range of pathological conditions but without any scientific knowledge about its action. Several studies have demonstrated its potentiality in cardiovascular, nephrological, nutritional, and other medical fields. Capsaicin exerts its actions thanks to the bond with transient receptor potential vanilloid subtype 1 (TRPV1). TRPV1 is a nociceptive receptor, and its activation starts with a neurosensitive impulse, responsible for a burning pain sensation. However, constant local application of Capsaicin desensitized neuronal cells and leads to relief from neuropathic pain. In this review, we analyze the potential adjuvant role of Capsaicin in the treatment of different pathological conditions either in internal medicine or dentistry. Moreover, we present our experience in five patients affected by oro-facial pain consequent to post-traumatic trigeminal neuropathy, not responsive to any remedy, and successfully treated with topical application of Capsaicin. The topical application of Capsaicin is safe, effective, and quite tolerated by patients. For these reasons, in addition to the already-proven beneficial actions in the internal field, it represents a promising method for the treatment of neuropathic oral diseases.
Food Science of Animal Resources

The aim of the study was to investigate the effect of bacteriocin-like inhibitory substance (BLIS) from Enterococcus faecium DB1 on cariogenic Streptococcus mutans biofilm. Crystal violet staining, fluorescence, and scanning electron microscopy analyses demonstrated that the BLIS from Enterococcus faecium DB1 (DB1 BLIS) inhibited S. mutans biofilm. When DB1 BLIS was co-incubated with S. mutans, biofilm formation by S. mutans was significantly reduced (p<0.05). DB1 BLIS also destroyed the preformed biofilm of S. mutans. In addition, DB1 BLIS decreased the viability of S. mutans biofilm cells during the development of biofilm formation and in the preformed biofilm. DB1 BLIS significantly decreased the growth of S. mutans planktonic cells. Furthermore, S. mutans biofilm on the surface of saliva-coated hydroxyapatite discs was reduced by DB1 BLIS. Taken together, DB1 BLIS might be useful as a preventive and therapeutic agent against dental caries caused by S. mutans.
Is There Any Relationship between Trichomonas vaginalis Infection and Male Urethritis Risk? A Systematic Review and Meta-Analysis

Background Male urethritis is one of the most common genital tract syndromes. Though the number of patients with urethritis is increasing worldwide, the cause of many cases of non-gonococcal urethritis (NGU) is still unknown. Objectives This study aimed to delineate the association between Trichomonas vaginalis (T. vaginalis) infection and male urethritis. Methods The literature was searched in PubMed, Scopus, and Web of Science databases using the search terms “urethritis,” “Trichomonas vaginalis,” “trichomoniasis,” and “male urethritis” up to February 2020. Overall risk difference(RD) was applied to assess the relationship between T. vaginalis infection and male urethritis. Results In total, seven articles were included in this systematic review and meta-analysis study. Our meta-analysis involved the review of case-control studies, including 2,242 urethritis cases and 929 individuals as controls. Among subjects examined for trichomoniasis, in the case group, 211 males were infected, and in the control group, 32 individuals were infected. The overall risk difference (RD) was 0.06, and the total reported p value was 0.00001. Although the result of our meta-analysis was not significant, it was shown that the risk of urethritis is 0.06 more in trichomoniasis patients than in the non-exposed group. Conclusion Findings from the included papers showed that trichomoniasis is not a risk factor for male urethritis. Although trichomoniasis alone is not the main cause of urethritis, it can be considered one of the risk factors in male urethritis. Therefore, in the future, it is necessary to perform further studies to clarify the detailed association between T. vaginalis infection and urethritis risk in male patients.
