Authors: Smith Peter Samuel , Alaa Aos , Riboli Sasco Eva , Bagkeris Emmanouil , El-Osta Austen 
Published: July 2023

Background
The COVID-19 pandemic fundamentally changed the way services are delivered. Self-care, including good hygiene practices and avoidance of risk was emphasised as the key measure to tackle the pandemic in the early stages.

Objective
To understand how self-reported professional attitudes, perceptions and practices of self-care have changed as a result of the COVID-19 pandemic.

Design
Cross-sectional online survey and semi-structured qualitative interview.

Setting
Health care.

Participants
304 healthcare professionals (HCPs).

Methods
A wide range of HCPs, including pharmacists, nurses, doctors, social prescribers and other designations took part in a 27-item anonymous online survey. Semi-structured qualitative interviews with nine healthcare professionals explored attitudes to and practices of self-care before and during the pandemic. Views were sought on the permanence and implications of changes. Data were analysed using routine statistics and thematic analysis to identify major themes.

Results
A total of 304 HCPs responded to the survey fully. Nine participated in a semi-structured interview. There was agreement that the importance of self-care has increased markedly during the pandemic. The percentage of respondents who felt that self-care was ’very’ important to their clients increased from 54.3% to 86.6% since the pandemic. Personal empowerment and capacity of service users to self-care increased significantly during the pandemic. Willingness of patients to engage (74%) and poor understanding of self-care (71%) were cited as the two main barriers to self-care. A close third was digital exclusion (71%), though 86% of respondents recommended online resources and 77% the use of smartphone apps. Survey respondents believed the changes to be permanent and positive. Interviewees reported a major, and positive move to self-care with the pandemic seen as an opportunity to be grasped, but professional education would have to be aligned to make the most of it. They raised concerns as to whether the shift to self-care was perceived by users as ’abandonment’ rather than ’empowerment’ and whether problems had been stored rather than dealt with through self-care and therefore whether the positive changes would continue after the pandemic.

Conclusion
Reporting their views before the pandemic, barely more than half of the professionals surveyed saw self-care as fundamentally important to the individuals they served. This changed to 86% as a result of the pandemic. Patient/client engagement with and understanding of self-care were reported as major barriers, as was digital exclusion, though increased technological solutions were used by all respondents. Concerns were raised that the permanence of the changes depended upon continued encouragement and empowerment of individuals to self-care and on its inclusion in professional education as a substantive subject.
Reconstruction of the Radiation Condition and Solution for the Helmholtz Equation in a Semi-infinite Strip from Cauchy Data on an Interior Segment
Authors: Achieng Pauline , Berntsson Fredrik , Kozlov Vladimir 
Published: July 2023

Abstract
We consider an inverse problem for the Helmholtz equation of reconstructing a solution from measurements taken on a segment inside a semi-infinite strip.
Homogeneous Neumann conditions are prescribed on both side boundaries of the strip and an unknown Dirichlet condition on the remaining part of the boundary.
Additional complexity is that the radiation condition at infinity is unknown.
Our aim is to find the unknown function in the Dirichlet boundary condition and the radiation condition.
Such problems appear in acoustics to determine acoustical sources and surface vibrations from acoustic field measurements.
The problem is split into two sub-problems, a well-posed and an ill-posed problem.
We analyse the theoretical properties of both problems; in particular, we show that the radiation condition is described by a stable non-linear problem.
The second problem is ill-posed, and we use the Landweber iteration method together with the discrepancy principle to regularize it.
Numerical tests show that the approach works well.
The Impact of Organizational Climate on Teacher Enthusiasm: A Two-Staged Structural Equation Modelling–Artificial Neural Network Approach
Authors: Punia Poonam , Bala Manju 
Published: July 2023

Abstract
The purpose of this article is to examine the influence of the school organizational climate on teacher enthusiasm. A sample of 600 teachers was drawn using a multi-stage random sampling method. The study variables were assessed using two main instruments: the organizational climate scale and teacher’s enthusiasm scale. A two-staged structural equation modelling and artificial neural network approach was used for the analysis. The study has unveiled the importance of the school’s organizational climate in determining the enthusiasm level of teachers. All the dimensions of organizational climate acted as significant predictors in the model. The study encourages periodic examination of the school climate and teachers’ enthusiasm to take any decisions or initiatives necessary to address deficiencies in schools.
Compact eight-shaped ISM-I band wearable antenna for wireless body area network applications
Authors: Utsav Ankur , Badhai Ritesh Kumar 
Published: July 2023

Abstract
The design and analysis of the electrically small eight-shaped wearable antenna for both on- and off-body communication is proposed in this paper. An eight-shaped radiating structure is placed over the jeans substrate and an I-shaped slot is introduced in the ground plane which makes the antenna resonates at the ISM-I band (2.4 GHz). The antenna has a compact size of 0.30λ
0 × 0.20λ
0 × 0.001λ
0, where λ
0 is the free space wavelength at the resonance frequency. The impedance bandwidth (≤−10 dB) of the antenna is 6.1 % and 5.8 % in free space and presence of a human body phantom respectively. The antenna design exhibits good gain along with an improved omnidirectional radiation pattern. The specific absorption rate (SAR) of the antenna averaged over 1 g of tissue is 0.21 W/kg at 2.45 GHz which is far below the FCC standard. The paper also discusses the bending analysis and the fundamental size limitations of the small antenna, concluding that it is suitable for practical use. The simulated results of the prototype are validated by the measured results.
Performance analysis of mmWave/sub-terahertz communication link for 5G and B5G mobile networks
Authors: Farooq Umar , Lokam Anjaneyulu 
Published: July 2023

Abstract
Millimeter (mmWave) and sub-terahertz communication is a key technology to support high data rate requirements of 5G and B5G mobile networks. However this field is still in its initial development stage because of the various technical difficulties in its practical implementation due to inherently distinct propagation properties of mmWave/sub-terahertz frequencies. A thorough investigation of mmWave/sub-terahertz communication link is required in order to successfully deploy these frequency bands in 5G and B5G mobile networks. This paper investigates the effect of atmospheric conditions like dry air, humidity, rain, snow, fog and foliage on the performance of the mmWave/sub-terahertz link. The work also presents a mathematical analysis of the coverage of mmWave/sub-terahertz communication link and investigates the effect of various parameters like frequency, bandwidth, transceiver antenna gain, path loss coefficient (LOS, NLOS case) and system noise on its performance.
On uniform statistical convergence

Published: July 2023

Abstract
This paper is a continuation of the so far performed studies on the concept of uniform statistical
convergence. We first characterize two inequalities concerning the uniform
statistical limit superior that lead to two core inclusion results for bounded
real sequences. Using the inverse Fourier transformation, we also give a criterion
on uniform statistical convergence, and study some factorization results of
the space of uniformly statistically convergent sequences. These results are
used to give a Korovkin-type approximation theorem.
The potential role of hydrophilic and hydrophobic liquid emulsifier-tailored sunflower wax/sunflower oil oleogels on the properties of whole wheat batter and sponge cakes
Authors: Bharti Deepti , Banerjee Indranil , Cerqueira Miguel Ângelo , Kim Doman , Pal Kunal 
Published: July 2023

Abstract
Sunflower oil (SO) oleogel was initially prepared using 5 % (w/w) sunflower wax, hydrophobic (Span 80), or hydrophilic (Tween 80) emulsifiers. This study involved the physicochemical characterization of the batter and cake prepared through partial and complete replacement of butter with the oleogels. Batter and cake properties were improvised in T80, prepared with oleogel containing 0.015 % (w/w) of Tween 80. The polarized micrograph of the T80 batter displayed a large number of air bubbles stabilized by the wax crystals. Starch gelatinization was found highest in T80 batter and could be related to the ability of hydrophilic emulsifiers to form a complex with starch. The FTIR spectra in the T80 batter and cake displayed a reduced peak for gluten content. T80 cake crumb showed a homogenous distribution of smaller air cells supporting its softness. A reduction in the firmness and hardness of T80 was obtained from the texture studies.
The combined effects of a higher-level verb distribution and verb semantics on second language learners’ restriction of L2 construction generalization
Authors: Zhang Xiaoyan 
Published: July 2023

Abstract
This study aims to uncover the combined effects of a higher-level verb distribution (i.e., the distribution of one-construction only verbs and alternating verbs across English) and verb semantics on Chinese EFL learners’ restriction of generalization of English prenominal past participles (PPPs). Three groups were formed: a lexicalist group, a generalist group, and a mixed group. During the treatment, the lexicalist group were exposed to input involving one-construction only verbs exclusively; the generalist group, alternating verbs only; the mixed group, both one-construction only and alternating verbs. An acceptability judgment task was employed to assess L2 learners’ construction generalization. The study found that, (1) the Lexicalist group exhibited significantly less generalization with the known state-change verbs than either the Generalist or the Mixed group, and significantly less generalization with the known non-state-change verbs than the Generalist group; (2) the Lexicalist group showed less generalization with extensive exposure one-construction only new verbs than the mixed group whereas the generalist and the mixed group did not differ significantly regarding construction preference of extensive exposure alternating new verbs; (3) the Lexicalist group were significantly less likely to generalize the PPP-only minimal exposure new verb than either the Generalist or Mixed group, and significantly less liable to generalize the relative clause (RC)-only minimal exposure new verb as opposed to the Generalist group; (4) moreover, the three groups differed significantly in regularization (operationalized as the number of participants who tended to accept each verb in only one of two competing constructions) of no exposure new verbs, with the lexicalist group producing more regularization than the other two groups.

Abstract

Objectives
To evaluate the association between maternal polymorphisms of NANOS3 rs2016163, HELQ rs4693089, PRIM1 rs2277339, TLK1 rs10183486, ERCC6 rs2228526, EXO1 rs1635501, DMC1 rs5757133, and MSH5 rs2075789 and fetal chromosomal abnormality.

Methods
This retrospective case-control study included 571 women with fetal chromosome abnormalities (330 pregnant women diagnosed with fetal aneuploidy, 241 with fetal de novo structural chromosome pregnancy) and 811 healthy pregnant women between January 2018 and April 2022. All the above polymorphisms were tested using SNaPshot.

Results
All the eight polymorphisms were analyzed for genotypes, alleles, under dominant and recessive genetic models. Significant distribution differences of TLK1 rs10183486 in fetal chromosome structural abnormality were found between the case group and control subjects who were <35 years of age [Genotype: p=0.029; Dominant: OR (95 %CI)=0.46 (0.25–0.82), p=0.01 and allele: OR (95 %CI)=0.47 (0.27–0.82), p=0.01 respectively], while no difference was found in the recessive model [OR (95 %CI)=2.49 (0.31–20.40), p=0.39]. In advanced age subgroups for fetal aneuploidy, significant differences were found in genotypes analysis of PRIM1 rs2277339 (p=0.008), allele analysis of TLK1 rs10183486 [OR (95 %CI)=0.62 (0.42–0.91), p=0.02]. For the fetal chromosome structural abnormality population, HELQ rs4693089 revealed a significant distribution difference (p=0.01) but not in the allele, dominant and recessive genetic models analysis (p>0.05 individually).

Conclusions
For older women, maternal PRIM1 rs2277339 and TLK1 rs10183486 polymorphisms may be associated with fetal aneuploidy, while HELQ rs4693089 may be associated with fetal chromosome structural abnormality. Also, carriers of T allele of TLK1 rs10183486 have a lower risk of fetal chromosome structural abnormality in younger women.
Performing best when it matters the most: evidence from professional handball
Authors: Bühren Christoph , Gabriel Marvin 
Published: July 2023

AbstractWe analyze the impact of psychological pressure on performance with over 5500 handball penalties thrown in either the decisive stage or the rest of the game during matches of the 2019/2020 season in the first three German handball leagues. Contrary to the choking under pressure phenomenon, most of the analyzed players perform best when it matters the most. The positive effect of pressure on performance is highest when the score is even or when the thrower’s team is trailing. We control for gender and psychological traits assessed with a survey. In our sample, female players score with a higher probability than male players. The positive impact of pressure is not significantly higher for female players.
Robinson v. Chief Constable of West Yorkshire Police: Taking Duty Back to Basics
Authors: Goudkamp James , Nolan Donal 
Published: July 2023

Abstract
In the United Kingdom, as in some other parts of the Commonwealth, the courts have long embarked on a search for a general formula which can be applied to determine whether a duty of care arises in any given negligence case. In 2018, the United Kingdom Supreme Court delivered its judgment in Robinson v. Chief Constable of West Yorkshire Police, in which a plurality strikingly rejected as misconceived attempts to identify such a general test. Duty cases, the Supreme Court held, are to be decided by reference to precedent where applicable, or (where no such precedent applies) by analogy with the existing authorities. This approach curtails the role of policy in the duty of care enquiry. In this article, the decision in Robinson is put in context and its significance explained. It is argued that the approach to the duty question adopted in Robinson should be welcomed. Not only is that approach the best of the alternatives available, but it is the only one that is consistent with the methodology of the common law and the rule of law.
On the role of metaphors in COVID-related political communication: an examination of Jacinda Ardern’s metaphorical language in managing the health crisis
Authors: Degani Marta 
Published: July 2023

Abstract
In comparison to many other countries across the world, New Zealand stands out as a positive example of successfully dealing with the COVID-19 pandemic during its first outbreak. A pivotal role in this has been attributed to Jacinda Ardern, New Zealand’s prime minister, who has been praised for her effective communication throughout the crisis and her capacity to connect empathetically to the people. The present study explores Ardern’s crisis discourse by focusing on her use of metaphors to talk about COVID-19, its transmission, and the measures adopted by the New Zealand government to contain its spread. This analysis, which adopts the framework of Critical Metaphor Theory, aims at disclosing which metaphors were used by Jacinda Ardern and whether there is anything exceptional in these metaphors and their usage that could relate to Ardern’s successful management of the health crisis in its initial phase. The data consists of eight post-Cabinet press conferences given by Ardern from the beginning of the outbreak at the end of February 2020 to the day when she declared that community transmission was over (27 April 2020).

Abstract
Rodents play an important role in the transmission of zoonotic diseases. This study investigated the prevalence of Leptospira spp. and Bartonella spp. in Mastomys natalensis and its ectoparasites (fleas and mites) in selected villages of Morogoro, Tanzania. Mastomys natalensis were captured live in fallow habitats using Sherman® traps and anesthetized using Halothane. Blood samples were obtained from the retroorbital sinus Ectoparasites were removed from the fur using a hard brush and preserved in 70 % ethanol. Real time–qPCR was used to detect Leptospira spp. and Bartonella spp. from Mastomys natalensis blood and ectoparasites respectively. The study revealed a relatively larger number of males than females captures. Leptospira spp. was demonstrated in one out of 100 Mastomys natalensis. For Bartonella spp., prevalence of (14 %) was recorded in mites with a higher proportion in mites from adult male Mastomys natalensis than females. Upon Sanger sequencing, four positive samples showed a complete sequence of the ITS gene. Indicating that all samples belonged to Uncultured Bartonella. Low prevalence of Leptospira spp. and a high prevalence of Bartonella spp. was observed in Mastomys natalensis. Further exploration of rodent pathogens is recommended to raise awareness of the role of commensal rodents in disease transmission via their ectoparasites.
Why Mereological Essentialism Applies to Mereological Aggregates
Authors: Moreland James Porter 
Published: July 2023

Abstract
This article’s purpose is to defend the depiction of ordinary-sized physical objects as mereological aggregates (MAs), to clarify what the ontology of an MA is, and to show why mereological essentialism (ME) applies to MAs that seem to be ubiquitous if we are to adopt what Frank Jackson calls “Serious Metaphysics” and refuse to broaden our ontology beyond what is (allegedly) bequeathed to us by physics and chemistry. To accomplish this goal, first, I clarify certain background issues that inform what follows and I identify certain constraints that relate to the contemporary ambivalence towards ME. Second, I present a primer on Husserlian mereology that provides a superior account of parts and wholes than the inadequate approach identified in the previous section. Third, I will offer a defense of ME as the correct approach to providing an ontological account of MAs. Finally, I will evaluate two defeaters against my thesis.

Published: July 2023

Abstract
The main objective of this investigation is to study the mechanical properties and microstructural features of rotary friction welded (RFW) UNS S42000 martensitic stainless-steel joints. The welded joints were stress relieved at 316 °C for 1 h holding followed by air cooling. The joints welded using the friction pressure of 60 MPa, forging pressure of 64 MPa, friction time of 18 s and forging time of 4 s exhibited superior tensile properties. Microstructure showed carbide precipitates and strain induced and partial strain induced martensite in weld zone for heat treated condition and coarser martensite and retained austenite for non-heat treated condition. Fractography for tensile tested samples reveals predominantly ductile mode of fracture for heat treated samples than non-heat treated condition. The Microhardness showed a higher value of hardness for the weld zone due to strain induced martensite and lesser hardness at PDZ due to partial strain hardened martensite.

Published: July 2023

Abstract
Herein we investigate the character of the near-field emission of a two- (2D) and novel three-dimensional (3D) probe geometries fabricated using 3D direct laser writing lithography. Near-field scans in x–y and y–z planes were measured both before and after the deposition of hyperbolic dispersion metamaterial (HMM) to further verify the directional propagation of the high wave-vector components present in the vicinity of the structures. Additional computational and theoretical characterization forewent the actual experimental measurements, showing a promising performance, particularly for the 3D Fresnel zone plate (FZP). Overall, the experimental data documents a subwavelength resolution with a significant signal enhancement in the focal spot of the 3D FZP and highly subwavelength depth of focus.
CdSe nanodots to nanorods in PVA films: effect of shape transition and loading on the opto-mechanical and biodegradation properties
Authors: Singh Sandeep , Garg Sangeeta , Saran Amit D. 
Published: July 2023

Abstract
Polyvinyl alcohol (PVA) films impregnated with CdSe nanoparticles were evaluated for the effect of morphology (from spherical to rod-shaped) and concentration of CdSe, on the optical and mechanical properties. CdSe nanodots and nanorods were synthesized by a modified microemulsion method with hydrazine hydrate as the shape modulator. CdSe nanoparticles and PVA/CdSe films were characterized by high resolution transmission electron microscopy (HR-TEM), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), UV–Vis spectroscopy and universal testing machine (UTM) analysis. The tensile strength and % elongation (at break) of PVA/CdSe films, increased from 32.8 MPa and 178 % (for CdSe nanorods) to 40.3 MPa and 259 % (for CdSe nanodots), respectively. The effect of loading of CdSe in PVA films, were evaluated at 0.1, 0.5, 1.0, 5.0 and 10 wt%. The tensile strength increased from 18.9 MPa (plain PVA) to 35.08 MPa (1 % CdSe) and increased upto 40 MPa for 10 % CdSe. The absorbance of PVA/CdSe films increased, while the reflectance and the transmittance decreased, with increasing wt% of CdSe in PVA films. The colour, density and water-vapour permeability of PVA/CdSe films, were also estimated. The biodegradability of PVA/CdSe films in soil was found to increase by 55 % as compared with PVA films.
