Phase State Influence on Photoluminescence of MAPb(BrxI1−x)3 Perovskites towards Optimized Photonics Applications

Perovskite halide has many advantages that attracted the attention of researchers in the last years, but many challenges prevent the use of halide perovskites in different applications. One of these challenges is the low thermal stability resulting in phase transitions with temperatures. Here, the photoluminescence (PL) characteristics and related phase transitions of different CH3NH3Pb(BrxI1−x)3 (MA(BrxI1−x)3)3 perovskites structures have been investigated under a wide temperature range. The work that has been conducted demonstrates that under temperature, the exciton behavior of the halide anions, I and Br, has a considerable impact on structural phases and the fluorescence process. The obtained results for the temperature dependence of PL for MAPb(BrxI1−x)3 showed a wide range of emission wavelengths, between 500–800 nm with a decrease in PL intensity with increasing temperature. In addition, the ratio of both bromine and iodine in MAPb(BrxI1−x)3 affects the range of phase transition temperatures, where at x = 0.00, 0.25, and 0.50 the first transition occurs below room temperature (orthorhombic to tetragonal) phase and the other occurs above room temperature (tetragonal to cubic) phase. Furthermore, increasing the proportion of bromine causes all the transitions to occur below room temperature. The presented findings suggest a suitable halide component under a temperature-controlled phase transformation to benefit these materials in photonics devices.
Temperature dependence of heterogeneous uptake of N2O5 by ammonium sulfate aerosol

We present laboratory measurements of the dependence of the uptake coefficient γ on temperature for removal of the NOx reservoir N2O5 by sub‐micron aerosols containing ammonium sulfate and ammonium hydrogen sulfate. Uptake coefficients were measured over the range 263–303 K at 50% RH, which varied in the range 0.005–0.036. A simple negative dependence of uptake on temperature is observed for ammonium sulfate over this range, while the form of the temperature dependence of uptake by ammonium hydrogen sulfate is more complex. The results consolidate those of an earlier less definitive study of the temperature effect on N2O5 uptake. Copyright © 2009 Royal Meteorological Society
WORKPLACE DEVIANT BEHAVIOUR OF HEALTHCARE WORKERS IN ISLAMIC HOSPITAL

Workplace Deviant Behavior has a negative impact on the accomplishment of organizational goals, creates social and economic losses, as well as interferes with a person's safety at work. This study aimed to determine whether Islamic personality and workplace spirituality had any direct effects on work-deviant behavior. Workplace spirituality was also put to the test as a mediator at the same time. Islamic personality was assessed using the Ummatic Personality Inventory (UPI), workplace spirituality was assessed using the Spirituality of Work Scale (SWS), and workplace deviant behavior was assessed using the Workplace Deviant Behavior Inventory (WDB). Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were used to analyze data from N = 311 healthcare professionals working in an Islamic hospital in Palembang, South Sumatera, Indonesia. Workplace spirituality, according to the study's findings, acted as a mediator between Islamic personality and deviant behavior at work, having a negative indirect influence. In conclusion, workplace spirituality and Islamic personality were the most significant influences on deviant behavior. In addition, coaching programs to improve collaboration and group cohesiveness among healthcare professionals should be implemented, as well as corrective teamwork training, to guarantee high productivity.
In Vitro Efficacy of Extracts and Isolated Bioactive Compounds from Ascomycota Fungi in the Treatment of Colorectal Cancer: A Systematic Review

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths worldwide. Despite the advances and success of current treatments (e.g., chemotherapy), there are multiple serious side effects which require the development of new treatment strategies. In recent years, fungi have gained considerable attention as a source of extracts and bioactive compounds with antitumor capabilities because of their antimicrobial and antioxidant properties and even their anti-inflammatory and antiviral activities. In the present review, a systematic search of the existing literature in four electronic databases was carried out in which the antitumor activity against CRC cells of Ascomycota fungi extracts or compounds was tested. The systematical research in the four databases resulted in a total of 883 articles. After applying exclusion and inclusion criteria, a total of 75 articles were finally studied. The order Eurotiales was the most studied (46% of the articles), and the ethyl acetate extraction was the most used method (49% of the papers). Penicillium extracts and gliotoxin and acetylgliotoxin G bioactive compounds showed the highest cytotoxic activity. This review also focuses on the action mechanisms of the extracts and bioactive compounds of fungi against CRC, which were mediated by apoptosis induction and the arrest of the cell cycle, which induces a notable reduction in the CRC cell proliferation capacity, and by the reduction in cell migration that limits their ability to produce metastasis. Thus, the ability of fungi to induce the death of cancer cells through different mechanisms may be the basis for the development of new therapies that improve the current results, especially in the more advanced stages of the CCR.
Analysing Objects to Tailor Environmental Preventive Conservation

This work explores the potential of analyzing individual objects to improve their preventive conservation. Previously, environmental recommendations have been based on an average or worst response of material groups. Cultural heritage objects are extremely variable and within a group such as archaeological iron a very wide range of responses are shown. Characterizing a single object’s response allows its environment to be tailored to its requirements and can enable significant resource and carbon footprint savings. Three main approaches are considered with a material explored in detail including preventive conservation ramifications. Composition analysis is investigated through the stability of limestones. The critical concentrations of soluble salts causing surface deterioration in one environment has been explored. A more rapid method of analyzing clays in acid insoluble fractions from drillings and undertaking that analysis non-invasively has been developed. Measuring deterioration rates is explored through oxygen consumption analyses of archaeological iron. The distributions of previously published data are explored and the changes in rates examined. A scheme for parchment based on shrinkage temperatures and observations is presented for the first time and its use illustrated with a newly acquired letter. The type of work required to produce these schemes is explored with leather.
Elliptical cross‐section model for the magnetic topology of magnetic clouds

In this work we present an extension of a previous model for the topology of magnetic clouds which takes into account their interaction with the solar wind. The main consequence of this interaction is the possible distortion of their cross‐section, that need no longer be circular during the propagation from the Sun to 1AU. The first approach to this deformation is to assume an elliptical geometry for the cross section although we consider a cylindrical shape for the clouds. Once we make the assumptions of an uniform radial component of the plasma current density and a null value for the radial component of the magnetic field vector, the solutions of the Maxwell equations and the continuity equation in stationary conditions, both expressed in elliptical coordinates, incorporate the expansion of the cross‐section of the cloud. To illustrate the model we present the fitting of four selected clouds with different magnetic field profiles. We show in all cases analyzed that the fits are indeed good and have eight free parameters.
Genomic Analysis Unveils the Pervasiveness and Diversity of Prophages Infecting Erwinia Species

Prophages are abundant elements integrated into bacterial genomes and contribute to inter-strain genetic variability and, in some cases, modulate the environmental behavior of bacteria, such as pathogen virulence. Here, we described prophage occurrence and diversity in publicly available Erwinia genome assemblies, a genus containing plant pathogens. Prophage-like sequences were identified and taxonomically classified. Sequence diversity was analyzed through intergenomic similarities. Furthermore, we searched for anti-phage defense systems in Erwinia spp. , such as DISARM, BREX, and CRISPR-Cas systems, and identified the putative targets of CRISPR spacers. We identified 939 prophage-like sequences in 221 Erwinia spp. genome assemblies. Only 243 prophage-like sequences were classified, all belonging to the Caudoviricetes class. The set of putative Erwinia prophages was mostly unique since only three sequences showed more than 70% intergenomic similarities to known Erwinia phages. Overall, the number and type of CRISPR-Cas systems were conserved within Erwinia species, with many spacers directed to the putative prophages identified. This study increased the knowledge of the diversity and distribution of Erwinia prophages, contributing to the characterization of genetic and ecological factors influencing Erwinia spp. environmental fitness.
Psychopathy among condemned capital murderers

Psychopathy is an important forensic mental health construct. Despite this importance, the research base of psychopathy among individuals convicted of capital murder is limited. Archival data were collected from a sample of 636 persons convicted of capital murder and sentenced to death in the State of California. Psychopathy was assessed using the Psychopathy Checklist – Revised (PCL‐R) instrument. Data on criminal careers and other behavioral disorders were also extracted. The sample mean PCL‐R total score was 23.31 (SD = 9.92) and one‐third of individuals in this sample were considered clinically psychopathic with PCL‐R total scores of 30 or greater. Factor analytic examination yielded support for four facets: affective, interpersonal, lifestyle, and antisocial. Criterion validity findings revealed positive correlations of psychopathy scores with Antisocial Personality Disorder (ρ = 0.72), Conduct Disorder (ρ = 0.46), sexual sadism (ρ = 0.24), Oppositional Defiant Disorder (ρ = 0.20), ADHD (ρ = 0.15), arrest charges (r = 0.56), prison sentences (r = 0.53), and age of arrest onset (r = −0.57). Individuals convicted of capital murder and sentenced to death reflect heterogeneity in psychopathy with some individuals exhibiting pronounced psychopathic features.
Wideband Low-Profile Eight-Port Eight-Wave Annular-Ring Patch Antenna Based on Using Eight Dual-Shorted Dual-Resonant Ring Sectors for 8 × 8 MIMO Mobile Devices

A wideband eight-port eight-wave annular-ring (AR) patch antenna for <inline-formula> <tex-math notation="LaTeX">$8\times $ </tex-math></inline-formula> 8 MIMO mobile devices is presented. The AR patch antenna is formed into eight dual-resonant 45o-ring sectors to radiate eight very-low-correlated or generally uncorrelated waves for <inline-formula> <tex-math notation="LaTeX">$8\times $ </tex-math></inline-formula> 8 MIMO application. Each ring sector is loaded with two shorting pins and excited by a simple probe feed to generate its half- and quarter-wavelength resonant modes at close frequencies to form a dual-resonant wide operating band. Additionally, all 16 shorting pins of the eight ring sectors have a same distance to the patch center, thereby forming a shorting circle to function like a circular metal wall in the AR patch. This makes the surface currents coupled from the excited ring sector to adjacent sectors to be mainly confined inside the shorting circle. Therefore, with the eight probe feeds located outside the shorting circle in the AR patch, enhanced port isolation is obtained. With the proposed design, the eight-port AR patch antenna having a low profile of 1.4 mm (about <inline-formula> <tex-math notation="LaTeX">$0.028\lambda $ </tex-math></inline-formula> at 5.9 GHz) and an outer diameter of 46 mm (about <inline-formula> <tex-math notation="LaTeX">$0.91\lambda $ </tex-math></inline-formula> at 5.9 GHz) can generate eight very-low-correlated waves over a wide band of about 5.9-7.2 GHz (fractional bandwidth 20% based on 3:1 VSWR for mobile device application). Also, the proposed antenna has a back ground plane and is especially suitable for on-metal surface application. The use of a single proposed antenna can be conveniently applied for the mobile device or Internet-of-Things (IoT) device to cover such as 5.925-7.125 GHz for <inline-formula> <tex-math notation="LaTeX">$8\times $ </tex-math></inline-formula> 8 MIMO operation in the possible new mobile communication spectrum.
The radio number of (Wn : 2) graphs

Abstract Let d(u, v) denote the distance between two distinct vertices of a connected graph G, and diam(G) be the diameter of G. A radio labeling c of G is an assignment of positive integers to the vertices of G satisfying d(u, v) + |c(u) — c(v) | ≥ diam(G) + 1. The maximum integer in the range of the labeling is its span. The radio number of G, rn(G), is the minimum possible span. If Wn denote the wheel on n vertices, then the graph obtained from Wn by subdividing each edge of the rim exactly twice is denoted by (Wn : 2). In this paper we prove that the radio number of (Wn : 2) is 5n + 2.
Dual-Energy Computed Tomography Applications to Reduce Metal Artifacts in Hip Prostheses: A Phantom Study

Metal components of hip prostheses cause severe artifacts in CT images, influencing diagnostic accuracy. Metal artifact reduction (MAR) software and virtual monoenergetic reconstructions on dual-energy CT (DECT) systems are possible solutions that should be considered. In this study, we created a customized adjustable phantom to quantify the severity of artifacts on periprosthetic tissues (cortical and spongious bone, soft tissues) for hip prostheses. The severity of artifacts was classified by different thresholds of deviation from the CT numbers for reference objects not affected by artifacts. The in vitro setup was applied on four unilateral and three bilateral configurations of hip prostheses (made of titanium, cobalt, and stainless steel alloys) with a DECT system, changing the energy of virtual monoenergetic reconstructions, with and without MAR. The impact of these tools on the severity of artifacts was scored, looking for the best scan conditions for the different configurations. For titanium prostheses, the reconstruction at 110 keV, without MAR, always minimized the artifacts. For cobalt and stainless-steel prostheses, MAR should always be applied, while monoenergetic reconstruction alone did not show clear advantages. The available tools for reducing metal artifacts must therefore be applied depending on the examined prosthetic configuration.
FLOW EQUATIONS FOR HAMILTONIANS

A method to diagonalize or block-diagonalize Hamiltonians by means of an appropriate continuous unitary transformation is reviewed. We will outline (i) the procedure for the elimination of the electron-phonon interaction and the construction of the effective attractive electron-electron interaction, and (ii) the application to some systems with electron-electron interaction (n-orbital model and Hubbard model).
Early Results after Exclusion of Popliteal Aneurysms with an Endoprosthesis

Objectives: To evaluate safety and efficacy of endoprosthesis implantation for the exclusion of popliteal artery aneurysm (PAA). Methods: Elective asymptomatic patients with aneurysm > 20 mm and symptomatic patients with endovascular therapy of PAA were included. The proportion of patients with critical limb ischemia (presence of rest pain or tissue loss) was high at 32.1%, 21.6% of the patients had acute ischemia with symptoms persisting shorter than 14 days. The primary study endpoint was the target lesion revascularization (TLR) rate at 12 months. Secondary endpoints included technical success, periinterventional adverse events, primary patency at 6, 12 and 24 months, TLR rate at 24 months, predictors on reintervention, change in in clinical symptoms using the Rutherford-Becker classification (RBC), amputation and mortality rate. One hundred thirty-four patients (68.3±10.6 years, 88.8% male) were treated with a Viabahn® endoprosthesis (W.L. Gore & Associates Inc., Flagstaff, AZ, USA). Results: The average aneurysm diameter was 2.5±0.87 cm. In 41%, occlusion of the aneurysm was present. TLR rate was 31.3% and 38.8% after 12 and 24 months, respectively. Primary patency rates were 69.1%, 52.3% and 42.6% at 6, 12 and 24 months, respectively. Univariate logistic regression analysis revealed age as a predictor of reintervention and in the multivariable analysis it was treatment with lysis. An improvement in RBC was seen at all-time points. Two major amputations (1.5%) were performed and the mortality rate at 24 months was 5.2%. Conclusion: Primary patency rate after endovascular exclusion of PAA is low. However, limb salvage rate is high.
The rolling unrestrained brachistochrone

We have generalized the unrestained brachistochrone problem to include rolling objects in order to construct a demonstration brachistochrone track. Due to the nature of the constraints this well‐posed extremal problem cannot be solved using the techniques of Euler and Lagrange. The solution, parametrized by a measure of the generalized cylinder’s moment of inertia, reduces to that for the (sliding) unrestrained brachistochrone in the limit of vanishing moment of inertia.
Association between the Perception of Behavior Change and Habitual Exercise during COVID-19: A Cross-Sectional Online Survey in Japan

In general, the perception of behavior change may be associated with habitual exercise. However, this association might not be well-understood due to the state of emergency of the COVID-19 pandemic. This study collected data from 1499 internet users aged 20–86 years living in Japan who participated in the online survey from 26 to 27 February 2021. Having a perception of behavior change was defined as preparation, action, and maintenance of the transtheoretical model. The habitual exercise was defined as 600 metabolic equivalent min/week or more based on the International Physical Activity Questionnaire. Multivariate logistic regression analysis was used to calculate the odds ratio of habitual exercise and a 95% confidence interval was estimated after adjusting for related factors. We found that perception of behavior change was positively associated with habitual exercise (adjusted odds ratio = 2.41, 95%CI = 1.89–3.08), and similar associations were found in states of emergency (2.69, 1.97–3.69) and non-emergency (2.01, 1.34–3.01). Moreover, women were negatively associated in all analyses with habitual exercise compared to men (0.63, 0.49–0.80; 0.65, 0.44–0.96; 0.62, and 0.45–0.84, respectively). Thus, the perception of behavior change may be involved in the implementation of habitual exercise, suggesting that women face difficulties in engaging in habitual exercise.
ENTREPRENEURIAL MOTIVATION AND ITS IMPACT ON MOMPRENEUR BUSINESS PERFORMANCE (STUDY ON SONGKET AND BATIK WOMEN ENTREPRENEURS IN JAMBI CITY)

Women entrepreneurs have become a rapidly growing phenomenon in the last decade. In the province of Jambi, the development of the MSME sector has also continued to increase, as has the case in the city of Jambi. Female MSMEs are dominated by housewives and those who already have children are also known as "Mompreneurs". The motivation of women entrepreneurs to enter into the world of business or to become entrepreneurs is not only because of business activities that might be in accordance with their hobbies but also because of the family's economic conditions which require them to be able to find additional income.This research is an empirical study by examining the impact of Mompreneur entrepreneurial motivation on business performance.
Biological Activity and Chemical Composition of Propolis from Various Regions of Poland

Propolis is one of the bee products, with multiple biological properties used in numerous applications. The research objective was to determine the chemical composition and biological properties (antibacterial, antifungal, antiviral, antioxidant, and cytoprotective activity) of propolis extracts collected from various regions of Poland. The results indicated that the total content of phenols (116.16–219.41 mg GAE/g EEP) and flavonoids (29.63–106.07 mg QE/g EEP) in propolis extracts depended on their geographic origin. The high content of epicatechin, catechin, pinobanksin, myricetin, and acids: vanillic and syringic in propolis samples was confirmed by chromatographic analysis. Moreover, the presence of caffeic acid phenethyl ester was confirmed in all samples. The origin of propolis also influenced the biological properties of its extracts. The propolis extracts were characterized by moderate DPPH free radical scavenging activity (29.22–35.14%), and relatively low ferrous iron chelating activity (9.33–32.32%). The results indicated also that the propolis extracts showed high activity in the protection of human red blood cells against free radicals generated from 2,2’-azobis(2-methylpropionamidine) dihydrochloride (AAPH). The extracts exhibited diversified activity against the tested pathogenic bacteria and limited activity against fungal strains. The research of selected propolis extracts showed that only 2 of 5 examined samples showed moderate activity against HPV (human papillomaviruses) and the activity depended on its geographical distribution.
Evaluation of the Warm Rain Formation Process in Global Models with Satellite Observations

AbstractThis study examines the warm rain formation process over the global ocean in global climate models. Methodologies developed to analyze CloudSat and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite observations are employed to investigate the cloud-to-precipitation process of warm clouds and are applied to the model results to examine how the models represent the process for warm stratiform clouds. Despite a limitation of the present study that compares the statistics for stratiform clouds in climate models with those from satellite observations, including both stratiform and (shallow) convective clouds, the statistics constructed with the methodologies are compared between the models and satellite observations to expose their similarities and differences. A problem common to some models is that they tend to produce rain at a faster rate than is observed. These model characteristics are further examined in the context of cloud microphysics parameterizations using a simplified one-dim.
