Some properties of the space of quasi-continuous functions

where {rj(t)}j=0 is the Rademacher system (see [2], Chap. 2) and ak(f) and bk(f) are the Fourier coefficients of f . By the space of quasi-continuous functions we mean the closure of the set of trigonometric polynomials with respect to the norm (1). The space of quasi-continuous functions and the QC-norm were introduced by Kashin and Temlyakov in [3] and [4]. There they obtained many interesting results on the properties of this norm. In particular, they proved the following result (see [4], Theorem 2.1): if n is a positive integer and f(x) = ∑n j=0 tj(x), where tj ∈ Ej for j = 0, . , n, then ∥f∥QC > 1 48π n ∑
Morphological and phylogenetic analyses reveal two new species in Conidiobolus s.s. (Conidiobolaceae, Entomophthorales) from China

﻿Abstract The genus Conidiobolus s.s. (Conidiobolaceae, Entomophthorales) has been delimited to accommodate members that produce microspores. Herein, morphological studies, combined with phylogenetic analysis based on the nuclear large subunit of rDNA (nucLSU), the mitochondrial small subunit of rDNA (mtSSU), and the elongation-factor-like gene (EFL) revealed two Conidiobolus s.s. species isolated from plant debris in China. Conidioboluslongiconidiophorussp. nov. is mainly characterised by its long primary conidiophores, while Conidioboluspolysporussp. nov. is diagnosed by 2–3 primary conidia arising from branched primary conidiophores. Phylogenetically, the former is grouped into a separate clade, while the latter is closely related to C.incongruus, but is morphologically distinguished by its larger primary conidia and branched conidiophores.
Understanding the life experiences of elderly in social isolation from the social systems perspective: using Hong Kong as an illustrating example

Aim The elderly in social isolation often referred to as older people who experience social alienation with little social support from their family, peers, and community suffer from a poor quality of life and well-being. Since their life experiences are affected by a range of factors from different levels, this study seeks to investigate their current life situations and experiences from a social systems perspective. Methods A qualitative study was conducted to enrich the understanding of their current life situations and experiences and to generate corresponding practice implications. In this study, there were 13 elderly participants in social isolation, which were users of a social service agency in Hong Kong. They took part in a semi-structured individual interview, sharing their life stories about their daily lives, social relationships, and sense of well-being. Qualitative results were analyzed based on these dimensions. Results Results showed that the elderly participants in social isolation had a low level of social support and participation in social activities. Their life experiences and situations were affected by multiple levels of factors that were interrelated. Conclusion The results support the application of the social systems perspective in investigating the living conditions of the elderly in social isolation. The corresponding practice implications were also discussed.
Academic advising overview in higher education (Literature review)

Academic Advising is an available opportunity offered by the university for all students. Success of this process based on cooperation between the Advisor Advisee and their institution.

The concept of advising students has been present in some shape since the inception of higher education in America. In the late eighteenth century, Since then until now it is raising strongly and became one of the most targeted and important demand in efficiency of higher education. The paper (literature Review) focus on the most related important areas of interest in academic advising and the common related investigated points, which contributed in strengthen of weaknesses and establish its development
A study on the relationship between teacher competency and job performance under human resource management in higher education

This study aimed to investigate the effects of Jiangsu University teachers’ competency and engagement on their job performance and determine whether teacher competency affects job performance through the mediating role of engagement. We constructed a theoretical model based on self-determination theory (SDT) and the job demand–resource model and validated it using structural equation modeling (SEM). The study sample comprised teachers from 8 types of undergraduate colleges and universities in Jiangsu Province, China. Three hundred and fifty-four university teachers were surveyed using the Teacher Competency Scale, the Utrecht Work Engagement Scale, and the Job Performance Scale. The results showed a significant positive effect of university teachers’ competency on their engagement and job performance. Additionally, SEM analysis showed a partial mediation effect of engagement in the relationship between teacher competency and job performance. The findings not only enrich our understanding of the mechanisms underlying the relationship between university teachers’ competency and job performance but also extend the scope of SDT and suggest practical discussions and recommendations.
Solution of Singularly Perturbed Differential-Difference Equations with Mixed Shifts Using Galerkin Method with Exponential Fitting

Galerkin method is presented to solve singularly perturbed differential-difference equations with delay and advanced shifts using fitting factor. In the numerical treatment of such type of problems, Taylor’s approximation is used to tackle the terms containing small shifts. A fitting factor in the Galerkin scheme is introduced which takes care of the rapid changes that occur in the boundary layer. This fitting factor is obtained from the asymptotic solution of singular perturbations. Thomas algorithm is used to solve the tridiagonal system of the fitted Galerkin method. The method is analysed for convergence. Several numerical examples are solved and compared to demonstrate the applicability of the method. Graphs are plotted for the solutions of these problems to illustrate the effect of small shifts on the boundary layer solution.
Existence of a Walrasian Equilibrium in Locally Convex Topological Vector Spaces, with Interdependent Utility Functions

In this paper we extend the well known result of existence of Walrasian equilibrium given in Debreu (1952) to economies modeled over topological vector spaces. Our work is closely related to the previous results of Yannelis-Pranhakar (1983), and Tan and Yuan (1999), but unlike these papers we prove the existence of a Walrasian equilibrium in infinite dimensional economies with interdependent and price-dependent utilities.
Unveiling the Prevalence and Factors of Workplace Bullying in Primary Healthcare Settings: A Cross-Sectional Study in Jeddah City, Saudi Arabia

Introduction Bullying in workplaces can lead to serious and deleterious effects on both the health and well-being of individuals. In a healthcare environment, bullying can lead to life-threatening adverse outcomes for patients and healthcare workers. The aim of this study was to evaluate the prevalence and factors of bullying among primary healthcare workers in Jeddah, Saudi Arabia. Methods This cross-sectional study targeted physicians and nurses in Jeddah healthcare centers and used a Negative Acts Questionnaire-Revised (NAQ-R) to evaluate participants’ exposure to bullying. The chi-square test was used to examine the relationship between the outcome and other variables. Results The majority of participants (59.8%) had more than 10 years of experience and were nurses (56.6%). The majority of participants (69.4%) scored below 33 on the NAQ-R scale, while 19.9% scored between 33 and 45, and 10.7% scored over 45. Most perpetrators were references/patients (22.4%), supervisors (19.2%), department managers, or general managers (19.2%). Of all participants, 28.8% had experienced workplace bullying (WPB), and 31.7% witnessed it over the past five years. Being subjected to WPB (P < 0.001), being bullied by a manager (P < 0.001), and experiencing and witnessing WPB over the past five years (P < 0.001) correlated with higher NAQ-R scores. Years of experience were significantly associated with NAQ-R scores (P = 0.016). Conclusions This study indicates bullying among a third of healthcare workers, mainly perpetrated by patients and managers. Years of experience and manager offenses, experiencing and witnessing WPB were associated with higher bullying rates. Therefore, there is an urgent need for antibullying policies, awareness campaigns, education programs, effective communication, conflict resolution, leadership training, and transparent culture to address this problem.
A tertiary care study to assess the effectiveness of ‘Supplement adherence kit’ on intake of nutritional supplements among pregnant women

Background: An antenatal mother undergoes significant changes throughout pregnancy and most of which occur during the second trimester. Supplements are important for normal growth and development of fetus, Deficiency of supplements during pregnancy leads to anemia and can have a negative impact on perinatal and maternal outcomes. These complications can be prevented by supplementing needed vitamins and minerals. Method: A Quasi-experimental study was conducted on 137 subjects visiting gynecology OPD enrolled by total enumerative sampling technique. Hemoglobin level and the adherence of supplements were assessed during the second trimester of antenatal mothers in both the groups. Results: Adherence of supplements has increased significantly (p value = 0.005, 0.004, and 0.040 for iron, folic acid, and calcium, respectively) among subjects in the experimental group. Results of SMAQ shows that there is increase in adherent mothers from 33.3% to 71.2% experimental group. Conclusion: Supplement adherence kit was effective in increasing supplement adherence level along with an improvement in hemoglobin levels among antenatal mothers in the Experimental group.
An Extreme Event in the Eyewall of Hurricane Felix on 2 September 2007

AbstractDuring a routine penetration into Hurricane Felix late on 2 September 2007, NOAA42 encountered extreme turbulence and graupel, flight-level horizontal wind gusts of over 83 m s−1, and vertical wind speeds varying from 10 m s−1 downward to 31 m s−1 upward and back to nearly 7 m s−1 downward within 1 min. This led the plane to rise nearly 300 m and then return to its original level within that time. Though a dropwindsonde was released during this event, the radars and data systems on board the aircraft were rendered inoperable, limiting the amount of data obtained.The feature observed during the flight is shown to be similar to that encountered during flights into Hurricanes Hugo (1989) and Patricia (2015), and by a dropwindsonde released into a misovortex in Hurricane Isabel (2003). This paper describes a unique dataset of a small-scale feature that appears to be prevalent in very intense tropical cyclones, providing new evidence for eye–eyewall mixing processes that may be related to intensity change.
Origin and Properties of Quiet-time 0.11–1.28 MeV Nucleon−1 Heavy-ion Population Near 1 au

Using measurements from the Advanced Composition Explorer/Ultra-Low Energy Isotope Spectrometer near 1 au, we surveyed the composition and spectra of heavy ions (He-through-Fe) during quiet times from 1998 January 1 to 2015 December 31 at suprathermal energies between ∼0.11 and ∼1.28 MeV nucleon−1. The selected time period covers the maxima of solar cycles 23 and 24 and the extended solar minimum in between. We find the following. (1) The number of quiet hours in each year correlates well with the sunspot number, year 2009 was the quietest for about 82% of the time. (2) The composition of the quiet-time suprathermal heavy-ion population (3He, C-through-Fe) correlates well with the level of solar activity, exhibiting SEP-like composition signatures during solar maximum, and CIR- or solar wind-like composition during solar minimum. (3) The heavy-ion (C–Fe) spectra exhibit suprathermal tails at energies of 0.11–0.32 MeV nucleon−1 with power-law spectral indices ranging from 1.40 to 2.97. Fe spectra soften (steepen, i.e., spectral index increases) smoothly with increasing energies compared with Fe, indicating a rollover behavior of Fe at higher energies (0.45–1.28 MeV nucleon−1). (4) Spectral indices of Fe and O do not appear to exhibit clear solar cycle dependence. (2) and (3) imply that during IP quiet times and at energies above ∼0.1 MeV nucleon−1, the IP medium is dominated by material from prior solar and interplanetary events. We discuss the implications of these extended observations in the context of the current understanding of the suprathermal ion population near 1 au.
Antibiotics Susceptibility Pattern of Bacterial Isolates Obtained from Potable Water Sources in Okerenkoko Community, Delta State, Nigeria

Safety and purity of drinking and cooking water sources in rural and riverine communities like Okerenkoko have posed a challenge for scientific discuss in recent times. Water devoid of both chemical and microbiological contaminants have been identified as a major key to wellness of any populace. In this study, eight potable water sources were obtained and evaluated for the study; the potable water sources obtained were treated to a 10-fold serial dilution and plated for aerobic bacterial, fungal, Salmonella-Shigella and Escherichia coli count. The antibiotics sensitivity testing employed the modified Kirby- Bauer method using the Abtek biological multiple disc. The multiple drug resistance was mathematically deduced using the standards and breakpoints. The NMU and George borehole had 5.8 Log10CFU/ml and 5.4 Log10CFU/ml for the total aerobic bacterial count while the total fungal count were 3.1 Log10CFU/ml and 3.6 Log10CFU/ml respectively. The culturable flora observed during the study were Bacillus sp, Escherichia sp. , Staphylococcus sp. , Streptococcus sp. , Shigella sp. , Proteus sp. , Pseudomonas sp. , Klebsiella sp. , Vibrio sp. Micrococcus sp. and Escherichia coli. The percentage resistance for the antibiotics revealed cefuroxime and ceftazidime had 64%, while nitrofurantoin had 71% and ofloxacin had 36%. Proteus sp. (1) had an MDR of 1.0, Klebsiella sp. (3) had 0.67 while Salmonella sp. and Escherichia coli had a MDR of 0.22 and 0.11. The findings of the study underscores the health challenges associated with the usage of the available potable water sources in Okerenkoko community. There is need for a community-wide campaign and sensitization on some basic water purification approaches as possible corrective actions to improve the quality of water; government must intervene and provide a routine and robust evaluation for both water safety and sanitary quality in rural communities.
Measurement of the Double-Differential Inclusive Jet Cross Section in Proton–Proton Collisions at √s = 13 TeV

A measurement of the double-differential inclusive jet cross section as a function of jet transverse momentum p T and absolute jet rapidity | y | is presented. The analysis is based on proton–proton collisions collected by the CMS experiment at the LHC at a centre-of-mass energy of 13 TeV. The data samples correspond to integrated luminosities of 71 and 44 pb − 1 for | y | < 3 and 3 . 2 < | y | < 4 . 7, respectively. Jets are reconstructed with the anti- k t clustering algorithm for two jet sizes, R , of 0.7 and 0.4, in a phase space region covering jet p T up to 2 TeV and jet rapidity up to | y | = 4.7. Predictions of perturbative quantum chromodynamics at next-to-leading order precision, complemented with electroweak and nonperturbative corrections, are used to compute the absolute scale and the shape of the inclusive jet cross section. The cross section difference in R , when going to a smaller jet size of 0.4, is best described by Monte Carlo event generators with next-to-leading order predictions matched to parton showering, hadronisation, and multiparton interactions. In the phase space accessible with the new data, this measurement provides a ﬁrst indication that jet physics is as well understood at √ s = 13 TeV as at smaller centre-of-mass energies.
Inverse spectral problems for differential operators on spatial networks

A short survey is given of results on inverse spectral problems for ordinary differential operators on spatial networks (geometrical graphs). The focus is on the most important non-linear inverse problems of recovering coefficients of differential equations from spectral characteristics when the structure of the graph is known a priori. The first half of the survey presents results related to inverse Sturm–Liouville problems on arbitrary compact graphs. Results on inverse problems for differential operators of arbitrary order on compact graphs are then presented. In the conclusion the main results on inverse problems on non-compact graphs are given. Bibliography: 55 titles.
Direct observation of the carrier transport process in InGaN quantum wells with a pn-junction

A new mechanism of light-to-electricity conversion that uses InGaN/GaN QWs with a p–n junction is reported. According to the well established light-to-electricity conversion theory, quantum wells (QWs) cannot be used in solar cells and photodetectors because the photogenerated carriers in QWs usually relax to ground energy levels, owing to quantum confinement, and cannot form a photocurrent. We observe directly that more than 95% of the photoexcited carriers escape from InGaN/GaN QWs to generate a photocurrent, indicating that the thermionic emission and tunneling processes proposed previously cannot explain carriers escaping from QWs. We show that photoexcited carriers can escape directly from the QWs when the device is under working conditions. Our finding challenges the current theory and demonstrates a new prospect for developing highly efficient solar cells and photodetectors.
Prognostic utility of 99mTc-MIBI single photon emission computerized tomography myocardial perfusion imaging in patients with ischemia and non-obstructive coronary artery disease

Objective The aim of our study was to evaluate the prognostic value of gated SPECT MPI in non-obstructed coronary arteries (INOCA) patients, sought to stratify patients more accurately and thus derive more reliable prognostic information. Materials and methods In total, 167 patients with INOCA were enrolled. The patients were divided into two groups according to their SSS. Patients were followed-up regularly in terms of major adverse cardiovascular event (MACE), including cardiac death, nonfatal myocardial infarction, stroke, re-hospitalization with angina pectoris, and recurrent angina pectoris. Kaplan-Meier curves and Cox's proportional hazards models were used to analyze survival and identify predictive factors. Results Adverse cardiac events occurred in 33 cases (19.8%). The rate of MACE was higher in the summed stress score (SSS) ≥4 group than in the SSS 0–3 group (30.1% vs. 9.5%, respectively, P = 0.001) and MACE-free survival was lower (annual MACE-free rates of 87.5% vs. 96.2%, respectively, P = 0.003). Event-free survival was consistently higher in patients with normal arteries than in those with non-obstructive coronary artery disease (annual MACE-free rates of 96.1% and 88.4%, P = 0.035). When the SSS and the CAG results were combined, patients with normal coronary arteries (SSS 0–3) had the best prognosis and those with non-obstructive coronary artery stenosis (SSS ≥ 4) had the worst. However, the early prognosis of patients with non-obstructive coronary artery disease and SSS of 0–3 was comparable to that of patients with normal coronary arteries and SSS ≥ 4 (annual MACE-free rates of 100%, 94.6%, 93.1%, and 78.2%, respectively). Multivariate Cox's regression indicated that the SSS [hazard ratio (HR) = 1.126, 95% confidence interval (CI) 1.042–1.217, P = 0.003] and non-obstructive coronary artery disease (HR = 2.559, 95% CI 1.249–5.246, P = 0.01) were predictors of adverse cardiac events. Conclusion SPECT MPI data were prognostic for INOCA patients, thus identifying groups at high risk. The long-term predictive efficacy of such data exceeded that of CAG data. A combination of the two measures more accurately stratified INOCA patients in terms of risk.
EVALUATION OF ANTERIOR SEGMENT PENTACAM CHANGES BEFORE AND AFTER PHACOEMULSIFICATION VERSUS COMBINED PHACOTRABECULECTOMY IN PRIMARY ANGLE-CLOSURE GLAUCOMA

Background: Both Phaco alone and Phaco-trab resulted in changes of the drainage angle, anatomy of the anterior chamber and reduction of intraocular pressure (IOP). The present study aimed to evaluate anterior segment Pentacam changes before and after phacoemulsification versus combined Phacotrabeculectomy in primary angle-closure glaucoma. Methods: This comparative, prospective, randomized controlled interventional study was conducted on 40 cases with primary angle closure glaucoma associated with cataract grade II or more, visual field loss compatible with cataract density admitted and underwent surgery. The study eyes were divided randomly into two groups; group (A) included cases that underwent standard phacoemulsification only while group (B) included cases that underwent combined phacoemulsification and trabeculectomy and both groups underwent pre and post-operative pentacam. Results: There were non-discernible differences between both groups regarding baseline UCVA, BCVA, K1, K2, K max over time, astigmatism , apex pachymetry, thinnest part corneal volume and anterior chamber depth or the follow-up at 1 week, 1 month, 3 months and 6 months. There was discernible difference between both groups regarding baseline anterior chamber angle and chamber volume follow-up at 1 month, 3 months and 6 months. No discernible difference was found regarding safety and efficacy between both groups. Conclusions: It's possible that both methods are similarly effective in curing PACG. There are non-significant pentacam changes between both procedures among cornea(k1,k2,k max, apex pachymetry, thinnest part), among anterior chamber (Ac depth, Ac angle, Chamber volume)
The Effects of an MMORPG on Thai EFL University Students’ Reading for Main Ideas

This study aimed to explore the effectiveness of using a massively multiplayer online role-playing game (MMORPG) as a tool for improving students’ English reading skills, specifically in identifying main ideas. The study employed a quasi-experimental method to gather comprehensive data, including pre-tests and post-tests consisting of 25 items each, to measure students’ performance before and after utilizing the MMORPG. Additionally, a 15-question questionnaire was used to assess students’ perceptions of using an MMORPG for reading instruction, and semi-structured interviews comprised of five questions were conducted to delve deeper into students’ experiences and opinions. A purposive sample of 35 students enrolled in an English reading course at a university in Nakhon Ratchasima, Thailand was selected for participation. The findings reveal a significant improvement in participants’ post-test scores compared to their pre-test scores (the results of participants’ post-test scores increased from the pre-test scores at 6.657, p = .000), indicating enhanced understanding of main ideas through MMORPG based instruction. Moreover, the majority of participants expressed enjoyment and enhanced learning experiences using the MMORPG approach. This research study has implications for course developers, emphasizing the importance of a systematic process in MMORPG design and exploring the pedagogical benefits of incorporating an MMORPG as an alternative teaching method for similar subjects.
