Authors: Zeng Hui‐Min , Jiang Zhan‐Guo , Zhang Huiwen , Mao Wei‐Tao , Gao Xuehui , Zhan Cai‐Hong 
Published: June 2021

AbstractIn this paper, three Compounds have been synthesized via conventional solution method. Compound 1 is a pure 2D (two dimensional) inorganic {CoO6Mo8O28}n framework. In the structure, the rare {γ‐Mo8O28} units connect into 1D chains via vertex‐sharing mode, and further assemble into 2D frameworks by {CoO6} octahedral linkers. This Compound was proved to be a cost‐effective pre‐catalyst with excellent catalytic performances due to presence of cobalt for water oxidation with low overpotential of 293 mV at 10.0 mA cm−2 and small Tafel slope of 53 mV dec−1. Furthermore, the electrocatalytic activity can be maintained for a quite long time with the retention rate of 94 % within 24 hours. Compared with 1D {γ‐Mo8O26}n (Compound 2) and 0D {α‐Mo8O26} (Compound 3), the Co−Mo complex catalyst based on compound 1, featured with Co‐doped 2D {Mo8O28}n porous framework and Co−Mo synergistic effect, which is supported by the high resolution XPS of Co 2p and Mo 3d, exhibits an extraordinary electrocatalytic reaction for water oxidation. The work shown here enriches inorganic polyoxometalate (POM) – based functional material applied to relief energy crisis.

AbstractBackgroundPatients with musculoskeletal pain in different body sites share common prognostic factors. Using prognosis to stratify and treatment match can be clinically and cost‐effective. We aimed to refine and validate the Keele STarT MSK Tool for prognostic stratification of musculoskeletal pain patients.MethodsTool refinement and validity was tested in a prospective cohort study, and external validity examined in a pilot cluster randomized controlled trial (RCT). Study population comprised 2,414 adults visiting U.K. primary care with back, neck, knee, shoulder or multisite pain returning postal questionnaires (cohort: 1,890 [40% response]; trial: 524). Cohort baseline questionnaires included a draft tool plus refinement items. Trial baseline questionnaires included the Keele STarT MSK Tool. Physical health (SF‐36 Physical Component Score [PCS]) and pain intensity were assessed at 2‐ and 6‐month cohort follow‐up; pain intensity was measured at 6‐month trial follow‐up.ResultsThe tool was refined by replacing (3), adding (3) and removing (2) items, resulting in a 10‐item tool. Model fit (R2) was 0.422 and 0.430 and discrimination (c statistic) 0.839 and 0.822 for predicting 6‐month cohort PCS and pain (respectively). The tool classified 24.9% of cohort participants at low, 41.7% medium and 33.4% high risk, clearly discriminating between subgroups. The tool demonstrated model fit of 0.224 and discrimination 0.73 in trial participants. Multiple imputation confirmed robustness of findings.ConclusionsThe Keele STarT MSK Tool demonstrates good validity and acceptable predictive performance and clearly identifies groups of musculoskeletal pain patients with different characteristics and prognosis. Using prognostic information for stratification and treatment matching may be clinically/cost‐effective.SignificanceThe paper presents the first musculoskeletal pain prognostic stratification tool specifically for use among all primary care patients with the five most common musculoskeletal pain presentations (back, neck, knee, shoulder or multisite pain). The Keele STarT MSK Tool identifies groups of musculoskeletal pain patients with clearly different characteristics and prognosis. Using this tool for stratification and treatment matching may be clinically and cost‐effective.
Pore‐scale analysis of a PEM fuel cell cathode including carbon cloth gas diffusion layer by lattice Boltzmann method
Authors: Molaeimanesh Gholam Reza , Dahmardeh Masoud 
Published: June 2021

AbstractOne of the parameters which can greatly affect (i.e., enhances or diminishes) the performance of a PEM fuel cell cathode is the GDL microstructure. In the present study, the role of carbon cloth GDL microstructure on the performance of a PEM fuel cell cathode is investigated, for the first time. In this regard, three carbon cloth GDLs with three different microstructures are reconstructed via merging bundles of carbon fibers with sinusoidal form; afterward, the passing reactive air through these GDLs is simulated at pore‐scale using lattice Boltzmann approach. The distributions of oxygen and water vapor through the carbon cloths and the distribution of current density on the catalyst layers are presented and analyzed. The results show that when the carbon cloth bundles consist of more fibers (i.e., having larger cross‐sections), the penetration of oxygen toward the catalyst layer is more difficult, and consequently, the average current density is smaller. Besides, the results reveal that the through‐plane compactness of carbon cloth microstructure does not bring a significant effect on the distribution of current density and species.
Modernizing thermal discharge assessments for the 21st century
Authors: Barnthouse Lawrence W. , Coutant Charles C. 
Published: June 2021

Abstract
A jointly prepared, interagency (US Environmental Protection Agency [USEPA] and the US Nuclear Regulatory Commission [USNRC]), §316(a) Technical Guidance Manual has been the primary guide to ecological studies of thermal discharges at power plants since 1977. It reflected contemporary ecological theory, which assumed that undisturbed populations and ecosystems possessed a balanced and relatively unchanging structure and function that could be disrupted by addition of heat from a thermal discharge. It was intended primarily to facilitate the licensing of proposed nuclear power plants and thus focused on predictive assessments. Since 1977, however, scientific and regulatory contexts of §316(a) assessments have changed. Ecologists abandoned the notion of “balance” in populations and ecosystems and now recognize that natural systems are always changing spatially and temporally. Regulatory emphasis has shifted from predictive assessments at new plants, largely based on thermal-tolerance laboratory data, to retrospective assessments based on field data at operating plants. We suggest updates to thermal-assessment studies based on modern ecological theory and recent thermal-assessment practice. The concepts we outline are fully consistent with statutory language and may assist in design and implementation of study plans by applicants and their consultants, development of discharge permits by USEPA or state agencies, and reviews of assessment documents by interested public and environmental organizations.

KEY POINTS
The 1977 EPA guidance on thermal effects assessment employed an outdated definition of the concept of “balance.” The guidance was also directed at predictive assessments of potential effects at power plants that had not yet been built. We develop a revised definition of the term “balanced indigenous population” that is consistent with modern ecological theory. We also provide recommendations for the design of thermal effects studies at existing power plants using site-specific ecological data.
Assessment of well‐being in the clinic: Using the state version of the short Scale of General Well‐Being as a clinical outcome measure
Authors: Holland Jennifer , Murphy David , Joseph Stephen 
Published: June 2021

AbstractObjectiveInterest in the concept of well‐being within clinical and applied psychology settings has increased, highlighting a need to develop appropriate measures. The aim was to adapt and test the validity of the 14‐item Scale of General Well‐Being (14‐SGWB) originally developed by Longo et al. (2018), as a clinical outcome measure.MethodStudy 1 is a psychometric study with 543 nonclinical participants, the wording of the 14‐SGWB was adapted, and tested for reliability and convergent validity. Study 2 investigated the adapted version with 125 clients over 10 therapy sessions, examining sensitivity, and reliable change cut‐off.ResultsThe final 14‐SGWB‐clinical tool has a single component structure, good convergent validity, and can assess reliable and clinically significant change.ConclusionMeasures that assess positive psychological change are important for the future development of clinical and applied psychology. The 14‐SGWB‐ct offers researchers a measure to extend evaluations of interventions to the effects on well‐being.
Psychosocial benefits and costs of activism among female migrant domestic workers in southern Spain
Authors: Aceros Juan C. , Duque Tatiana , Paloma Virginia 
Published: June 2021

AbstractEconomic migrant women often experience oppressive living and working conditions in the receiving societies. Activism is a liberatory behavior these women may employ to transform such situations. This study explores the activism experience of female migrant domestic workers from Latin America settled in southern Spain, in terms of its psychosocial benefits and costs. A purposeful sample of eleven activist migrant women engaged in a grassroots organization of domestic workers and eight members of social organizations supporting their activities were interviewed in‐depth individually. After a qualitative content analysis approach to the data, the study presents activism as a community engagement behavior with benefits such as the strengthening of social ties, sense of community, opportunities for sharing stories of oppression, and psychological empowerment. Activism also emerged as a demanding activity requiring high investments in time by activists and producing interpersonal conflicts, hopelessness, and burnout in some cases. Such costs may pose limits to its potential to produce well‐being and liberation, implying challenges for research, intervention, and activism sustainability.

AbstractPopulation‐based immunoglobulin G (IgG) seroprevalence studies in asymptomatic individuals in Latin America are scarce. The objective of the study was to estimate the prevalence and geographic distribution of IgG antibodies induced by natural SARS‐CoV‐2 infection in asymptomatic adults, 5–8 months after the first case was reported in a northeastern state of Mexico. This was a population‐based cross‐sectional study carried out in Nuevo Leon during August–November 2020. Individuals ≥18 years with no previous diagnosis or symptoms suggestive of COVID‐19 were consecutively screened in one of the busiest subway stations. Also, a search for eligible individuals was done from house‐to‐house, after selecting densely populated geographic sectors of each of the municipalities of the metropolitan area (n = 4495). The IgG antibodies to SARS‐CoV‐2 nucleocapsid protein were analyzed. The IgG antibody positivity rate was 27.1% (95% confidence interval [CI]: 25.8, 28.4); there were no differences by sex or age (p > 0.05). Analysis by month showed a gradual increase from 11.9% (August) to 31.9% (November); Week 39 had the highest positivity rate (42.2%, 95% CI: 34.2, 50.7). Most people did not have evidence of previous SARS‐CoV‐2 infection. Preventive measures and promotion of the COVID‐19 vaccine should be strengthened.
On the present habitats and ecology of Vertigo pseudosubstriata Ložek, 1954 (Mollusca, Gastropoda, Vertiginidea) in Central Asia and its distribution history in Central and Eastern Europe

Published: June 2021

ABSTRACTThe small terrestrial gastropod Vertigo pseudosubstriata Ložek, 1954 is one of the rarest glacial indicator species in the Pleistocene of Central and Eastern Europe. In all, this species has been found at only about 15 sites in Europe. V. pseudosubstriata was initially described as a fossil in Central Europe and was discovered only later alive in Central Asia. With regard to its modern distribution, 25 habitats with V. pseudosubstriata have been examined in Tien Shan and in the central and southern Altai. These findings seem to capture the contemporary distribution of the species and provide information on the boundaries of its ecological requirements. These data are of great significance for the interpretation of the fossil assemblages. Since the few fossil specimens in Europe date from very different glacial periods in the Elsterian, Saalian Complex and Weichselian, it can be concluded that V. pseudosubstriata apparently immigrated in at least three distinct waves. Most of the Pleistocene specimens in eastern Central Europe and Eastern Europe are reported from archaeological sites of the Upper Middle Weichselian (Gravettian), roughly between 33 and 29 ka cal
bp. In this paper, we review all reported modern and fossil occurrences and discuss the species' ecological range.

AbstractBackgroundMotor response to dopaminergic therapy is a characteristic of patients with Parkinson's disease (PD). Whether nondopaminergic neurotransmitters contribute to treatment response is uncertain.ObjectivesThe aim of this study is to determine whether putaminal y‐aminobutyric acid (GABA) levels are associated with dopaminergic motor response.MethodsWe assessed putaminal GABA levels in 19 PD patients and 13 healthy controls (HCs) utilizing ultra‐high field proton magnetic resonance spectroscopy. Motor performance was evaluated using the Movement Disorder Society—Unified Parkinson's Disease Rating Scale, Part III, in the ON and OFF states. Statistical analysis comprised group comparisons, correlation analysis, and multiple linear regression.ResultsIn PD, GABA levels were significantly higher compared to HCs (1.50 ± 0.26 mM vs. 1.26 ± 0.31 mM, P = 0.022). Furthermore, GABA levels were independent predictors of absolute and relative dopaminergic treatment response.ConclusionsOur findings indicate that elevated putaminal GABA levels are associated with worse dopaminergic response in PD, emphasizing the essential role of nondopaminergic neurotransmitters in motor response. © 2021 The Authors.

Reducing outpatient gastrostomy tube complications
Authors: Emmons Deanna 
Published: June 2021

AbstractObjectiveTo monitor the effectiveness of a multidisciplinary education protocol for gastrostomy tube (GT) use and care for patients to reduce complications postplacement.MethodsBaseline assessment included a preintervention/intervention design through quantitative measures to determine reduction in the number of GT complications postprocedure following implementation of a patient education protocol for 16 patients in the study.InterventionA multidisciplinary approach was used in protocol development for standardizing patient education. Verbal, written, and hands‐on demonstration methods for GT care were used to provide multiple education pathways to increase patient knowledge. Over the progression of 8 months (July 2019 to March 2020), patients with a new GT were followed postprocedure (1–2 weeks prior to starting radiation treatments) and throughout their course of radiation treatments (typically 6–7 weeks).ResultsAll 16 patients (100%) in the intervention group were included in the final analysis. GT complications were reduced from 91% in the preintervention group (n = 11) to 37% in the intervention group (n = 16). The most significant reduction occurred in technique issues, which decreased from 36% (n = 4) to 0%.ConclusionsImplementation of a multidisciplinary approach with multiple educational sessions prior to GT placement and use led to increased patient knowledge and reduced GT complications.

Published: June 2021

AbstractThe present work intended to investigate the effect ofDalbergia sissoowood waste on physical, mechanical, and thermal properties of poly(lactic acid) (PLA)‐based composites. The composite specimens, containing wood waste (2.5%, 5%, 7.5%, and 10% by weight) mixed with PLA granules, were prepared by melt compounding. It was found that increased wood waste content resulted in higher modulus, porosity, and water absorption with decreased density, tensile strength, impact strength, and stress at break. Nevertheless, the flexural strength values of the composites were similar to unfilled PLA and they remained almost constant irrespective of the wood waste content. Differential scanning calorimetry analysis revealed that the presence of wood waste content increased the glass transition and cold crystallization temperature of the PLA composites. Moreover, the fractured surfaces of the composites were examined with a scanning electron microscope to study the possible failure mechanisms. The conducted investigations demonstrated that low‐cost wood waste‐based composites can be used as an environmentally and economically attractive substitute for lightweight applications.
Seminal plasma metabolomics reveals lysine and serine dysregulation as unique features distinguishing between prostate cancer tumors of Gleason grades 6 and 7

Published: June 2021

AbstractBackgroundProstate cancer (PCa) is a metabolic disease. Most men are diagnosed with low grade indolent disease and differentiating these men from those who have life threatening cancer is a challenging but important clinical dilemma. There are currently limited biomarkers that can distinguish between the indolent Gleason grade 6 and higher‐grade disease. Moreover, some individuals initially diagnosed with low grade disease progress to higher grade disease. Currently prostate biopsies are the only reliable methods of stratifying risk, but biopsies can cause significant morbidity, sample only a small portion of the gland and are costly. Therefore, biomarkers distinguishing between indolent and aggressive patterns of PCa are urgently required to minimize biopsy‐associated morbidity, prevent over‐treatment of indolent PCa and to better stratify patients for appropriate treatment.MethodsSeminal fluid samples were collected from normal individuals (n = 13) Before infertility treatment and histologically confirmed PCa patients (n = 51). 1H Nuclear magnetic resonance spectroscopy and orthogonal partial least square discriminant analysis were used to compare the populations.ResultsAlterations in amino acids levels, specifically lysine and serine and changes in glycolytic intermediates were the most significant metabolic features associated with differences between healthy controls and PCa and between Gleason grade 6 (GS6) and Gleason grade 7 (GS7) samples. Orthogonal partial least square plots discriminated healthy controls from PCa samples (R
2 = 0.54, Q
2 = 0.31; area under the receiver operating characteristics curve [AUC] = 0.96), and GS6 from GS7 samples (R
2 = 0.62, Q
2 = 0.49; AUC = 0.98) based on lysine and serine content.ConclusionThis study suggests that seminal plasma metabolomics profiling of seminal fluid is a promising means of differentiating indolent from aggressive disease. Particularly, lysine and serine levels may be able to differentiate GS6 from GS7 disease.

Non-conservative effects on spinning black holes from world-line effective field theory
Authors: Goldberger Walter D. , Li Jingping , Rothstein Ira Z. 
Published: June 2021

Abstract
We generalize the worldline EFT formalism developed in [4–9] to calculate the non-conservative tidal effects on spinning black holes in a long wavelength approximation that is valid to all orders in the magnitude of the spin. We present results for the rate of change of mass and angular momentum in a background field and find agreement with previous calculations obtained by different techniques. We also present new results for both the non-conservative equations of motion and power loss/gain for a binary inspiral, which start at 5PN and 2.5PN order respectively and manifest the Penrose process.
Size and momentum of an infalling particle in the black hole interior
Authors: Haehl Felix M. , Zhao Ying 
Published: June 2021

Abstract
The future interior of black holes in AdS/CFT can be described in terms of a quantum circuit. We investigate boundary quantities detecting properties of this quantum circuit. We discuss relations between operator size, quantum complexity, and the momentum of an infalling particle in the black hole interior. We argue that the trajectory of the infalling particle in the interior close to the horizon is related to the growth of operator size. The notion of size here differs slightly from the size which has previously been related to momentum of exterior particles and provides an interesting generalization. The fact that both exterior and interior momentum are related to operator size growth is a manifestation of complementarity.
