Authors: Krzyzaniak Natalia , Forbes Connor , Clark Justin , Scott Anna Mae , Mar Chris Del , Bakhit Mina 
Published: May 2022

BackgroundAsymptomatic bacteriuria (ASB) is common among residents of residential aged care facilities (RACFs). However, differentiating between an established urinary tract infection and ASB in older adults is difficult. As a result, the overuse of dipstick urinalysis, as well as the subsequent initiation of antibiotics, is common in RACFs.AimTo find, appraise, and synthesise studies that reported the effectiveness, harms, and adverse events associated with antibiotic treatment for older patients with ASB residing in RACFs.Design and settingA systematic review using standard Cochrane methods of RACF residents with ASB using antibiotics against placebo, or no treatment.MethodThree electronic databases (PubMed, EMBASE, and CENTRAL), clinical trial registries, and forward–backward reference checks of included studies were searched.ResultsNine randomised controlled trials, comprising 1391 participants were included; two of which used a placebo comparator, and the remaining seven used no therapy control groups. There was a relatively small number of studies assessed per outcome and an overall moderate risk of bias. Outcomes related to mortality, development of ASB, and complications were comparable between the two groups. Antibiotic therapy was associated with a higher number of adverse effects (four studies; 303 participants; risk ratio [RR] 5.62, 95% confidence interval [CI] = 1.07 to 29.55, P = 0.04) and bacteriological cure (nine studies; 888 participants; RR 1.89, 95% CI = 1.08 to 3.32, P = 0.03).ConclusionOverall, although antibiotic treatment was associated with bacteriological cure, it was also associated with significantly more adverse effects. The harms and lack of clinical benefit of antibiotic use for older patients in RACFs may outweigh the benefits.

Published: May 2022

BackgroundThere is little knowledge of the diagnostic accuracy of screening programmes for frailty in primary care settings.AimTo assess a two-step strategy consisting of the administration of the FRAIL scale to those who are non-dependent and aged ≥75 years, followed-up by measurement of the Short Physical Performance Battery (SPPB) or gait speed in those who are positive.Design & settingCross-sectional and longitudinal cohort study. Analysis of primary care data from the FRAILTOOLS project at five European cities.MethodAll primary care patients consecutively attending were enrolled. They received the index tests, plus the Fried frailty phenotype (FP) and the frailty index to assess their frailty status. Mortality and worsening of dependency in basic and instrumental activities of daily living (BADL and IADL) over 1 year were ascertained.ResultsPrevalence of frailty based on FP was 14.9% in the 362 participants. A FRAIL scale score ≥1 had a sensitivity of 83.3% (95% confidence interval [CI] = 73.1 to 93.6) to detect frailty. A positive result and an SPPB score <11 had a sensitivity of 72.2% (95% CI = 59.9 to 84.6); when combined with a gait speed <1.1 m/s, the sensitivity was 80.0% (95% CI = 68.5 to 91.5). Two-thirds of those screened as positive were not frail. In the best scenario, sensitivities of this last combination to detect IADL and BADL worsening were 69.4% (95% CI = 59.4 to 79.4) and 63.6% (95% CI = 53.4 to 73.9), respectively.ConclusionCombining the FRAIL scale with other functional measures offers an acceptable screening approach for frailty. Accurate prediction of worsening dependency and death need to be confirmed through the piloting of a frailty screening programme.

In situ observation of formation of Si protrusions by local melting of a Si narrow current path using resistive heating together with electron beam irradiation
Authors: Nishimura Takashi , Tomitori Masahiko 
Published: May 2022

Abstract
Silicon (Si) protrusions were grown by local surface melting and resolidified on a Si(111) fragment with a narrow current path that was fabricated using a microgrinder at the center of the fragment. The narrow path was resistively heated by passing a current through it until it burned. The surface of the narrow path and fragment gradually melted with increasing current, and the melted Si started to flow from the narrow path to its sides owing to the surface tension of the melted Si. When the fragment surface near the path was locally irradiated with an electron-beam, melted Si accumulated in the irradiation region, resulting in Si protrusions of ∼600 μm in height. The formation mechanism of the Si protrusion was discussed based on in situ optical microscope observations up to the burn-out of the Si narrow path.
A Ku-band radial transit time oscillator with high-power capacity
Authors: Yang Chaochao , Meng Jin , Wang Haitao , Deng Bingfang 
Published: May 2022

Abstract
In order to improve the power capacity of a high-power microwave (HPM) generator, a Ku-band radial transit time oscillator (RTTO) with a trapezoidal resonator is designed. Compared with the traditional RTTO, both the modulation cavity and the extraction cavity are trapezoidal, which can modulate the electron beam more effectively. At the same time, the conductor tips on both sides of the cavity are farther, which helps to avoid the enhancement of the local electric field at the conductor tip, so as to reduce the risk of radio frequency (RF) breakdown. In particle-in-cell (PIC) simulation, the proposed Ku-band RTTO can output HPMs with the power of 1.66 GW and the frequency of 14.33 GHz, and the working efficiency is 41%. The maximum radial electric field intensity in the extraction cavity is 0.76 MV cm−1, lower than the RF breakdown threshold of metallic materials, which can effectively improve the power capacity of the device.

Authors: Katari Naresh Kumar , Gundla Rambabu , Reddy Phani Kumar , Vanam Anuradha , Talatam Aruna , Motohashi Noboru , Gollapudi Rao 
Published: May 2022

Background: Human epidermal growth factor receptor 2 (Her2) gene located in human chromosome17, encodes Her2 tyrosine kinase protein, and is overexpressed in breast cancer cells. Her2 is activated on phosphorylation of tyrosine by adenosine triphosphate (ATP). Nonetheless, Her2 excessively partakes in the development and prognosis of specific types of aggressive breast cancers. Therefore, Her2 inhibition therapy is primary target for the treatment of aggressive breast cancer. At present, lapatinib is one of the Food and Drug Administration approved Her2 inhibitors used in cancer therapy. In molecular docking process, glabrene with slightly higher binding energy competitively bound to the active receptor site comparable to lapatinib and ATP. Therefore, glabrene could emerge as a potential candidate for restricting Her2 overexpressed breast cancer.
Objective: The present study aimed to demonstrate the inhibitory activity of glabrene, an isoflavene and xenoestrogen found in liquorice root, along with known Her2 inhibitor, lapatinib.
Methods: ATP, lapatinib, and glabrene were docked on human Her2 protein 3D structure which revealed glabrene as a competitive Her2 inhibitor akin to lapatinib. Results: The docking results suggested the binding site similarities of ATP, lapatinib, and glabrene. The binding energies of docked ATP, lapatinib, and glabrene complexes with Her2 were −9.1 kcal/mol, −10.5 kcal/mol, and −11.3 kcal/mol, respectively.
Conclusion: The in silico docking simulation of ATP, lapatinib, and glabrene suggested that glabrene is likewise a competitive Her2 inhibitor.
On Sum Sets and Convex Functions
Authors: Stevens Sophie , Warren Audie 
Published: May 2022

In this paper we prove new bounds for sums of convex or concave functions. Specifically, we prove that for all $A,B \subseteq \mathbb R$ finite sets, and for all $f,g$ convex or concave functions, we have $$|A + B|^{38}|f(A) + g(B)|^{38} \gtrsim |A|^{49}|B|^{49}.$$
This result can be used to obtain bounds on a number of two-variable expanders of interest, as well as to the asymmetric sum-product problem. We also adjust our technique to prove the three-variable expansion result $$|AB+A|\gtrsim |A|^{\frac{3}{2} +\frac{3}{170}}\,.$$Our methods follow a series of recent developments in the sum-product literature, presenting a unified picture. Of particular interest is an adaptation of a regularisation technique of Xue, originating in a paper of Rudnev, Shakan, and Shkredov, that enables us to find positive proportion subsets with certain desirable properties.

Published: May 2022

Abstract
Little is known about the origin of the fastest stars in the Galaxy. Our understanding of the chemical evolution history of the Milky Way and surrounding dwarf galaxies allows us to use the chemical composition of a star to investigate its origin and to say whether it was formed in situ or was accreted. However, the fastest stars, the hypervelocity stars, are young and massive and their chemical composition has not yet been analyzed. Though it is difficult to analyze the chemical composition of a massive young star, we are well versed in the analysis of late-type stars. We have used high-resolution ARCES/3.5 m Apache Point Observatory, MIKE/Magellan spectra to study the chemical details of 15 late-type hypervelocity star candidates. With Gaia EDR3 astrometry and spectroscopically determined radial velocities we found total velocities with a range of 274–520 km s−1 and mean value of 381 km s−1. Therefore, our sample stars are not fast enough to be classified as hypervelocity stars, and are what is known as extreme-velocity stars. Our sample has a wide iron abundance range of −2.5 ≤ [Fe/H] ≤ −0.9. Their chemistry indicates that at least 50% of them are accreted extragalactic stars, with iron-peak elements consistent with prior enrichment by sub-Chandrasekhar mass Type Ia supernovae. Without indication of binary companions, their chemical abundances and orbital parameters indicate that they are the accelerated tidal debris of disrupted dwarf galaxies.
How Do Magnetic Field Models Affect Astrophysical Limits on Light Axion-like Particles? An X-Ray Case Study with NGC 1275
Authors: Matthews James H. , Reynolds Christopher S. , Marsh M. C. David , Sisk-Reynés Júlia , Rodman Payton E. 
Published: May 2022

Abstract
Axion-like particles (ALPs) are a well-motivated extension to the standard model of particle physics, and X-ray observations of cluster-hosted AGN currently place the most stringent constraints on the ALP coupling to electromagnetism, g

a
γ
, for very light ALPs (m

a
≲ 10−11 eV). We revisit limits obtained by Reynolds et al. using Chandra X-ray grating spectroscopy of NGC 1275, the central AGN in the Perseus cluster, examining the impact of the X-ray spectral model and magnetic field model. We also present a new publicly available code, ALPro, which we use to solve the ALP propagation problem. We discuss evidence for turbulent magnetic fields in Perseus and show that it can be important to resolve the magnetic field structure on scales below the coherence length. We reanalyze the NGC 1275 X-ray spectra using an improved data reduction and baseline spectral model. We find the limits are insensitive to whether a partially covering absorber is used in the fits. At low m

a
(m

a
≲ 10−13 eV), we find marginally weaker limits on g

a
γ
(by 0.1–0.3 dex) with different magnetic field models, compared to Model B from Reynolds et al. (2020). A Gaussian random field (GRF) model designed to mimic ∼50 kpc scale coherent structures also results in only slightly weaker limits. We conclude that the existing Model B limits are robust assuming that β
pl ≈ 100, and are insensitive to whether cell-based or GRF methods are used. However, astrophysical uncertainties regarding the strength and structure of cluster magnetic fields persist, motivating high-sensitivity RM observations and tighter constraints on the radial profile of β
pl.
L’inconscient contaminé par la réalité
Authors: Franckx Christine 
Published: May 2022

La crise climatique s’est inscrite dans la vie psychique des citoyens, elle a bien infiltré les rêves et contaminé l’inconscient. Cela est pourtant peu signifié dans le matériel psychique en séance, malgré le fait que ses effets sont omniprésents dans le monde externe. Dans cet article, le problème complexe de la crise environnementale est abordé sous un angle psychanalytique. Des hypothèses pour le désavouement généralisé dans la vie quotidienne ainsi que dans l’approche analytique de cette catastrophe pour l’humanité sont proposées. Dans la deuxième partie de l’article, l’auteur évoque des pistes pour « rêver » la relation de l’être humain avec son environnement naturel, ce qui pourrait faciliter une intégration intrapsychique et repositionner l’homme dans sa grande famille écobiologique. Ainsi le clivage résultant d’un vécu de contamination traumatisant de la vie psychique par des circonstances extérieures pourrait commencer à être levé. L’impact psychique de la crise climatique se trouve à la croisée des chemins de la psychopathologie individuelle et collective.
La quête inachevée de la singularité disciplinaire
Authors: Déloye Yves 
Published: May 2022

Cet article entend contribuer à une histoire sociale de la science politique à travers l’étude critique de l’institution particulière qu’est la Revue française de science politique ( RFSP ) : il s’agit de mieux comprendre ce que l’histoire d’une revue apporte à la compréhension de la genèse d’une discipline scientifique et ce que l’évolution de celle-ci fait à l’histoire d’une revue. Au-delà du contenu des articles publiés qu’une histoire intellectuelle privilégierait à raison, il s’agit de regarder du côté des acteurs qui ont fait la revue – et partant la discipline à cette époque fondatrice – et des choix éditoriaux qui ont été les leurs (ce que nous appellerons le « paratexte » de la revue). Loin de révéler une structuration rapide de la science politique française, l’enquête menée sur les premières décennies de l’histoire de la revue (1951-1970) permet de rendre compte du pragmatisme des pères fondateurs de la RFSP , de leur souci de doter la discipline des outils méthodologiques et des références (notamment bibliographiques) qui justifieront ses développements ultérieurs, bref des bricolages et hésitations qui sont souvent au fondement des connaissances scientifiques.

Pour relever le défi de l’urgence écologique, le Green New Deal devra être « décolonial ». Il devra rompre avec le modèle dominant et l’occidentalisation du monde, par le démantèlement des structures néocoloniales et des mécanismes d’exploitation des peuples et de leur environnement. Il ne sauvera la planète qu’en visant l’égalité sociale, raciale et de genre, la relocalisation de l’économie et de nouveaux rapports à la nature.
Au-delà de l’attentat de Marseille du 9 octobre 1934
Authors: Bausardo Thomas 
Published: May 2022

L’attentat de Marseille du 9 octobre 1934, qui voit la mort du roi Alexandre de Yougoslavie et du ministre français des Affaires étrangères Louis Barthou, occupe une place centrale dans la relation entre la France et la Yougoslavie durant l’entre-deux-guerres, mais n’épuise pas la manière dont le terrorisme l’a façonnée. Les années qui précèdent l’attentat connaissent en effet le développement d’une coopération antiterroriste en matière policière et de renseignement entre les deux États contre les menaces représentées par l’ORIM et l’Oustacha. Cette coopération est mise à l’épreuve lors de l’enquête consécutive à l’attentat de Marseille et se délite alors que la Yougoslavie se rapproche de l’Allemagne nazie.
Fostering Resilience in Nursing Students in the Academic Setting: A Systematic Review
Authors: Diffley Donna Marie , Duddle Maree 
Published: May 2022

Background:
Nursing students experience similar stress-related health issues as RNs and have been identified as a group of health professionals who may be unable to cope effectively with stress. Studies have emphasized the need to incorporate resilience programs at higher education institutions for nursing students. However, it is important to identify strategies that increase resilience to ensure future programs are effective and follow an evidence-based approach.

Method:
This mixed-methods systematic review was conducted using Joanna Briggs Institute (JBI) methodology. A comprehensive literature search was conducted using JBI Critical Appraisal Checklists for assessment and quality appraisal. Data were extracted and synthesized thematically.

Results:
Category intervention strategies were identified and used to cluster three intervention strategy themes. Three outcome themes also were synthesized to examine strategy effectiveness.

Conclusion:

Findings indicate multicomponent interventions that include information sharing, skill application, and reflective learning are effective in helping nursing students manage stress and increase resilience.

Enhancing the Nursing Student Experience: A Mixed-Methods Approach
Authors: Jackson Molly 
Published: May 2022

Background:
There is a lack of published literature linking the nursing student experience and program evaluation relationship. A mixed-methods approach was used to improve the nursing student experience through faculty, staff, and student engagement.

Method:
A student experience initiative was launched in 2016. A 3-year plan was developed by an external consultant and steering committee. A process to prioritize improvement needs across all programs was used, with program-specific plans, faculty engagement, and results in a graduate-entry nursing program.

Results:
Student satisfaction ratings on exit surveys increased from 1 of 10 at the start of the initiative in 2016 to 8 of 10 in 2021. Continuous improvement and engagement are needed to maintain student satisfaction in nursing education.

Conclusion:

This initiative can serve as a framework for other educational partners to consider adopting to enhance the nursing student experience and improve program outcomes.

Results:

There were no significant differences in JCAT-NE scores for students (
M
= 133.43,
SD
= 19.12) and faculty (
M
= 136.34,
SD
= 22.73) (t[159] = 0.82,
p
= .42); however, there were significant differences in JCAT-NE scores based on level of experience. For students, JCAT-NE scores were significantly higher for sophomores than for seniors (F[2, 114] = 4.9,
p
= .01). For faculty, advanced beginner and competent faculty had significantly higher scores compared with proficient and expert faculty (t[42] = 2.36,
p
= .02).

Conclusion:

More needs to be done to establish a fair and just culture in schools of nursing.
