Published: May 2021

AbstractBackgroundPsychosocial factors have been associated with poor outcomes in patients with rotator cuff disease. Emotional health is one of these factors, and relationships between emotional health and outcome measures evaluated before and after physical therapy have not been reported.AimTo investigate the associations of baseline emotional health status with pre‐treatment, post‐treatment, and pre‐to‐post changes in pain, disability and health‐related quality of life in patients with rotator cuff disease.MethodsForty‐one patients with rotator cuff disease were included. Emotional health was measured with the emotions domain of the Western Ontario Rotator Cuff Index (WORC). The outcomes were the WORC‐total, the Shoulder Pain and Disability Index, and the numeric pain rating scale. All outcomes were measured at baseline and 6‐week follow‐up.ResultsThe baseline emotional health score and the outcomes scores were moderate to strong, and weak to moderate correlated at baseline and at follow‐up, respectively. There was no correlation between the baseline emotional health score and the changes in the outcome measures from baseline to follow‐up.ConclusionsLower baseline emotional health status was associated with worse outcomes in pain, disability and health‐related quality of life at baseline and follow‐up in patients with rotator cuff disease. However, the changes in these outcome measures from baseline to follow‐up were not correlated with the baseline emotional health status. In clinical practice, an assessment of patients' emotional health status using standardised measures may help to predict post‐treatment outcomes, and a multidisciplinary cooperation (e.g., among physical therapists and psychologists) may enhance outcomes.

AbstractAimThe main objective of this paper was to establish types of health status in the group of practicing nurses.DesignPositive psychology defines human health as the underlying resource for all life activities, including professional work. Practicing nurses are exposed to a variety of professional pressures, most notably high‐stress burden. Long‐term functioning in conditions of work‐related overburden and stress may compromise the health status of nurses and make them vulnerable to somatic or psychosomatic conditions.MethodsIn this study, we used original worksheets for collecting socio‐economic data and health‐related data, Orientation to Life Questionnaire (SOC‐29), General Health Questionnaire (GHQ‐28), Brief COPE Inventory (Mini‐COPE) and the somatic symptom scale. K‐means clustering analysis for cases was used to identify types of health status among the surveyed nurses.ResultsThis survey discovered that specific types of health status can be distinguished among practicing nurses. The nurses represented various types of health status, levels of the sense of coherence and the use of stress management strategies.

AbstractCobalt oxide nanoparticles (6 nm) supported both inside and outside of hollow carbon spheres (HCSs) were synthesized by using two different polymer templates. The oxidation of benzyl alcohol was used as a model reaction to evaluate the catalysts. PXRD studies indicated that the Co oxidation state varied for the different catalysts due to reduction of the Co by the carbon, and a metal oxidation step prior to the benzyl alcohol oxidation enhanced the catalytic activity. The metal loading influenced the catalytic efficiency, and the activity decreased with increasing metal loading, possibly due to pore filling effects. The catalysts showed similar activity and selectivity (to benzaldehyde) whether placed inside or outside the HCS (63 % selectivity at 50 % conversion). No poisoning was observed due to product build up in the HCS.

AbstractObesity disproportionately affects rural populations; however, there is limited research examining disparities in bariatric surgery outcomes between patients from rural versus urban areas. This study aimed to compare the demographic characteristics of patients undergoing bariatric surgery from rural versus urban bariatric areas and to explore differences in weight‐loss outcomes between these groups. A retrospective chart review identified a sample of 170 patients (52 rural, 118 urban) who underwent Roux‐en‐Y gastric bypass or vertical sleeve gastrectomy procedures over a 1‐year period. Data collected included age, race, gender, insurance status, surgery type, height, and pre‐ and postoperative weights at 3 and 6 months. Significant differences in race, ethnicity, and surgery type were observed between rural/urban patients (ps < 0.05). Patients from rural areas demonstrated significantly greater percent total weight losses at 3 months (p = 0.018; however, there were no significant differences between groups at 6 months (p > 0.05). The results suggest that patients from rural counties experience postoperative weight‐loss outcomes comparable to those of their urban counterparts.

AbstractOur study estimates the prevalence of Internet addiction in Czech adolescents as well as differences by gender and school type. A total of 3,950 adolescents (n = 1,940 boys, n = 2,010 girls) from 11 to 19 years of age (M = 15.73, SD = 1.99) participated in the research. They completed the Internet Addiction Test, which consists of subscales for Salience, Excessive Use, Neglect Work, Anticipation, Lack of Control, and Neglect Social Life. The results indicate that adolescent girls have higher levels of internet addiction. In boys, unlike girls, internet addiction was associated with a reduction in social relationships and interactions. Our findings show interesting differences between adolescent girls and boys and the type of school attended in the Czech population in terms of Internet addiction.

AbstractConcerns surround whether insensitive (or any) energetic materials are more dangerous to handle when exposed to abnormal thermal environments. This study characterizes the residual material remaining after LX‐17 (92.5 % 1,3,5‐triamino 2,4,6‐trinitro benzene (TATB) and 7.5 % Kel‐F) is exposed to various thermal environments in a sealed small‐scale vessel cook‐off test reactor (heated at 0.1 to 100 °C/min until the reactor opened at 3000 psi (20.7 MPa)). Previous work has shown no additional sensitivity of these residues as evaluated by small‐scale safety analysis, but characterization on the molecular scale indicates the TATB is transformed to more reactive compounds as well as the residue could be precursors to toxic gases. The solids and chars were characterized by various analytical methods. Heat‐flow measurements indicated exothermic release is due to a mixture of residual TATB and related decomposition products (which may be more energetic). The N/C and O/N ratios indicated a material much more degraded than TATB. Primarily, the solids were a network of amorphous C inter‐dispersed with N and O. Types of bonding include C−C, C−N, N−H, N−C, N=C, N≡C, C−O=, and −OH. Solvent extracts of the solids showed TATB decomposition intermediates benzo‐furazans and benzo‐furoxans, substituted TATB (mono‐nitroso, hydroxyl, and chlorinated) along with several unidentified smaller molecules. These results indicate thermal treatment produces an amorphous carbon residue with heteroatoms incorporated through differing functionality, varying depending upon the thermal severity of exposure. These structures also could further decompose producing toxic light gases (such as cyanide).
Improved coarse‐grained model for studying sequence dependent phase separation of disordered proteins

Published: May 2021

AbstractWe present improvements to the hydropathy scale (HPS) coarse‐grained (CG) model for simulating sequence‐specific behavior of intrinsically disordered proteins (IDPs), including their liquid–liquid phase separation (LLPS). The previous model based on an atomistic hydropathy scale by Kapcha and Rossky (KR scale) is not able to capture some well‐known LLPS trends such as reduced phase separation propensity upon mutations (R‐to‐K and Y‐to‐F). Here, we propose to use the Urry hydropathy scale instead, which was derived from the inverse temperature transitions in a model polypeptide with guest residues X. We introduce two free parameters to shift (Δ) and scale (µ) the overall interaction strengths for the new model (HPS‐Urry) and use the experimental radius of gyration for a diverse group of IDPs to find their optimal values. Interestingly, many possible (Δ, µ) combinations can be used for typical IDPs, but the phase behavior of a low‐complexity (LC) sequence FUS is only well described by one of these models, which highlights the need for a careful validation strategy based on multiple proteins. The CG HPS‐Urry model should enable accurate simulations of protein LLPS and provide a microscopically detailed view of molecular interactions.

Published: May 2021

AbstractThe impact of model grid spacing and land‐surface resolution (LSR) on convective precipitation are investigated for areas with different orographic complexities. ICOsahedral Nonhydrostatic (ICON) model simulations were performed for six days having weak large‐scale forcing using six model grid spacings (in metres): Numerical Weather Prediction (NWP) (, ) and Large‐Eddy Simulation (LES) physics simulations (, , , and ) in a nested set‐up. Concerning LSR, we focused on simulations with LSRs of 1,250 and 5,000 m, keeping the model grid spacing at 156 m. The onset of precipitation in is earlier by 0.5–2 hr, while LSR modifications show a similar onset compared with . The relative percentage difference (RPD) of areal mean daily precipitation across LES physics simulations decreases consistently with model grid spacing for most of the cases. The RPD of precipitation in is considerably higher (75th percentile: ≈155%) than that of the LSR runs at resolutions of both 1,250 and 5,000 m, with 75th percentiles of ≈7% and ≈22%, respectively. To investigate the processes causing the differences in precipitation characteristics, like onset time and amount, the heat and moisture budgets of and were compared. The results show that, at the initial stage of cloud formation, a higher number of smaller clouds are formed in compared with . The small clouds in are subject to considerable evaporative cooling at their edges and shell regions, due to entrainment processes. As a result, these clouds often dissolve before they can grow deep. Later on, cloud aggregation in also enables precipitation. The delayed onset of precipitation and reduced areas of aggregated clouds having low precipitation rates are the main reasons for less precipitation in than in .
An unsupervised approach for fault diagnosis of power transformers

Published: May 2021

AbstractElectrical utilities apply condition monitoring on power transformers (PTs) to prevent unplanned outages and detect incipient faults. This monitoring is often done using dissolved gas analysis (DGA) coupled with engineering methods to interpret the data, however the obtained results lack accuracy and reproducibility. In order to improve accuracy, various advanced analytical methods have been proposed in the literature. Nonetheless, these methods are often hard to interpret by the decision‐maker and require a substantial amount of failure records to be trained. In the context of the PTs, failure data quality is recurrently questionable, and failure records are scarce when compared to nonfailure records. This work tackles these challenges by proposing a novel unsupervised methodology for diagnosing PT condition. Differently from the supervised approaches in the literature, our method does not require the labeling of DGA records and incorporates a visual representation of the results in a 2D scatter plot to assist in interpretation. A modified clustering technique is used to classify the condition of different PTs using historical DGA data. Finally, well‐known engineering methods are applied to interpret each of the obtained clusters. The approach was validated using data from two different real‐world data sets provided by a generation company and a distribution system operator. The results highlight the advantages of the proposed approach and outperformed engineering methods (from IEC and IEEE standards) and companies legacy method. The approach was also validated on the public IEC TC10 database, showing the capability to achieve comparable accuracy with supervised learning methods from the literature. As a result of the methodology performance, both companies are currently using it in their daily DGA diagnosis.
Assessing the Effectiveness of Structured Word Inquiry for Students in Grades 3 and 5 With Reading and Spelling Difficulties: A Randomized Controlled Trial

Published: May 2021

AbstractResearch syntheses have demonstrated that morphological instruction can improve the literacy skills of poor readers and spellers. However, studies have used a wide variety of training methods. Questions remain about what type of morphological instruction is most effective and under which circumstances. In this study, we conducted a randomized controlled trial evaluating the effectiveness of Structured Word Inquiry for poor readers and spellers. Structured Word Inquiry teaches students the logic of the English spelling system via instruction in morphology and etymology. Students in grades 3 and 5 with poor reading and spelling skills were randomly assigned to receive either Structured Word Inquiry instruction or a comparison instruction method involving robust vocabulary instruction and reciprocal teaching. Instruction was delivered by teaching assistants over the course of a full school year. After training, there were few differences between the groups in terms of literacy or vocabulary skills. However, teaching assistants found Structured Word Inquiry instruction challenging to deliver, which is likely to have impacted the results. Our findings have implications for the nature and content of morphological instruction for poor readers and spellers, and for future attempts to scale up the delivery of morphological interventions.

Abstract

Background
Generalized pustular psoriasis (GPP) is a rare and severe type of psoriasis. Previous studies have reported that metabolic syndrome and its components have been associated with psoriasis.

Objective
To investigate the association of metabolic syndrome-related single-nucleotide polymorphisms (SNPs) and GPP in Chinese Han population.

Materials and Methods
One hundred and thirty-six (136) GPP patients and 965 healthy controls were recruited in the study. Approximately, 4 ml peripheral venous blood was collected from each participant. After collection, second-generation sequencing was used to detect genetic polymorphism of 15 SNPs. The plink 1.07 software package was used for statistical analysis.

Results
Rs805303 (p = 0.01, OR = 0.70) and rs3177928 (p = 3.18E−07, OR = 2.66) in HLA were significantly different between the two groups. Moreover, rs4506565 (p = 1.41E−03, OR = 2.72) and rs7901695 (p = 9.39E−04, OR = 2.82) in TCF7L2 were significantly associated with GPP in patients without a previous history of PsV. Genotype analysis of rs4506565 and rs7901695 showed that under the recessive model, genotype frequencies of rs4506565 (p = 0.00, OR = 18.52) and rs7901695 (p = 0.00, OR = 18.44) were significantly different between GPP patients and healthy controls.

Conclusion
Rs805303 and rs3177928 in HLA may increase the risk of GPP in the Chinese Han population. TCF7L2 may be a risk factor for GPP in patients without a previous history of PsV.
An Efficient and Short Total Synthesis of (−)‐Heliannuol A by Intramolecular Ullmann C−O Coupling for the Construction of an Eight‐Membered Ether Ring
Authors: Tsubogo Tetsu , Okamura Fumiya , Omori Akiho , Uchiro Hiromi 
Published: May 2021

AbstractHerein, we report a method for the synthesis of eight‐membered cyclic ethers by a direct C−O bond connection using an intramolecular Ullmann coupling reaction based on our previously published methodology. We found that allelopathically active heliannuol A could be rapidly synthesised using this method. The use of a strongly coordinating 4‐pyrrolidinopyridine ligand accelerates the reaction rate and leads to the C−O coupling reaction of a typically inaccessible sterically bulky tertiary alcohol. Furthermore, this method circumvents the protection and deprotection steps, presenting a new strategy for the syntheses of benzannulated eight‐membered ring structures.
IO‐TiO2/PCN‐222 Heterostructure with a Tightly Connected Interface and Its Photocatalytic Activity
Authors: Yang Kai , Ye Jin , Zhao Yi , Ge Kai , Cao Jiayu , Wang Shuang , Zhang Zhiheng , Zhang Yue , Yang Yongfang 
Published: May 2021

AbstractIO‐TiO2/PCN‐222 heterostructure is built by combining the narrow band gap metalloporphyrin metal‐organic framework (PCN‐222) with the wide gap inverse opal TiO2 (IO‐TiO2). PCN‐222 was grown in situ on the surface of the IO‐TiO2 pore wall under hydrothermal conditions, which formed a tightly connected interface and allowed the rapid separation and transfer of electrons and holes. The IO‐TiO2/PCN‐222 possessed a high photodegradation efficiency of doxycycline hydrochloride (DH) and the degradation rate constant of IO‐TiO2/PCN‐222 is 0.02456 min−1, which is about 7.24, 3.95 and 5.27 times that of P25, IO‐TiO2 and PCN‐222, respectively. The high photocatalytic activity of IO‐TiO2/PCN‐222 is attributed to the high adsorption capacity of DH, strong absorption of visible light, and the fast separation and transfer ability of electrons and holes in the tightly connected heterointerface.

Published: May 2021

AbstractThe crystal structures of three Imidazo [2, 1‐b] [1, 3, 4] thiadiazole derivatives were determined by single crystal x‐ray diffraction method. All compounds are crystallized under monoclinic crystal system, P21 space group. In solid‐state, the crystal structures are primarily stabilized by C−H…O hydrogen bonds. The chloro and bromo substituted structures exhibits sigma hole involved S…O and S…N non‐bonding interactions. A detailed analysis of crystal packing with the evaluation of interaction energies of molecular pairs extracted from both PIXEL and quantum chemical methods were presented in detail. In addition, Hirshfeld 2D fingerprint plots are used to estimate intermoleular interactions quantitatively. The iso‐structurality present in the crystal packing was investigated using XPAC analysis. The molecular electrostatic potential (MEP) was mapped to identify the reaction sites of the molecules. Further nonlinear optical properties are calculated using Density functional theory.

Revisiting Zuckerman's (1999) categorical imperative: An application of epistemic maps for replication
Authors: Goldfarb Brent , Yan Liyue 
Published: May 2021

AbstractResearch SummaryWe revisit Zuckerman's (1999) “The Categorical Imperative: Securities Analysts and the Illegitimacy Discount,” which theorizes that when organizations are recognized as legitimate players in a category, they perform better. A replication exercise fails to reproduce two of three sets of results. Assisted by data shared by the original author, we find evidence that the inconsistency is due to a coding error in the original and differences between analyst data sets. We illustrate the use of epistemic maps and evaluate the theory's predictive power across a broad set of plausible empirical assumptions and also for a subsequent time period. The results are not robust. We conclude that these data provide little evidence to support strategic recommendations. Challenges and remedies for replication are discussed.Managerial SummaryThis paper replicates a 1999 study “The Categorical Imperative: Securities Analysts and the Illegitimacy Discount” (Zuckerman, 1999). A key implication of the 1999 study is that firms should actively seek to be covered by analysts who specialize in their industries, and that a failure to be covered by analysts who are industry specialists will lead to lower capital market valuations. Our replication exercise indicates that there is insufficient evidence to recommend actively managing coverage along this dimension.
