AbstractNOx is the main pollutant in the air, which causes many harmful effects on society. The V2O5/TiO2 catalysts are very important to reduce the NOx from the heat engine plants and vehicle exhausts. However, various reasons will affect the performance of the catalysts. In this paper, the polymerization state of surface VOx of supported V2O5/TiO2 catalysts was controlled by changing the pH value of the impregnation precursor solutions, and the redox and acidity properties of the catalysts can be adjusted consequently. The Raman spectroscopy, 51V magic‐angle spinning nuclear magnetic resonance (MAS NMR), H2‐temperature‐programmed reduction (H2‐TPR), NH3‐temperature‐programmed desorption (NH3‐TPD), NH3‐temperature‐programmed oxidation (TPO) and 15NH3‐NO‐O2‐temperature‐programmed surface reaction (TPSR) were mainly used for the characterization and properties tests of the samples. Although all catalysts in this work had similar surface morphology and the same vanadium loading, the catalyst oxidability decreased while acidity increased with the increasing of VOx polymerization, which causes the NO conversion increases with the increasing of VOx polymerization below 300 °C in selective catalytic reduction (SCR) de‐NOx reaction. This work will promote the advance in catalysis and anti‐pollution fields for human and nature.

Authors: Schwarze Thomas , Riemer Janine 
Published: November 2020

AbstractHerein, we report on the synthesis of highly K+/Na+ selective fluorescent probes in a feasible number of synthetic steps. These K+ selective fluorescent probes, so called fluoroionophores, 1 and 2 consists of different highly K+/Na+ selective building blocks the alkoxy‐substituted N‐phenylaza‐18‐crown‐6 lariat ethers (ionophores) and “green” (cf. coumarin unit in 1) or “red” (cf. nile red unit in 2) fluorescent moieties (fluorophores). The fluorescent probes 1 and 2 show K+ induced fluorescence enhancement factors of 4.1 for 1 and 1.9 for 2 and dissociation constants for the corresponding K+ complexes of 43 mM (1+K+) and 18 mM (2+K+) in buffered aqueous solution. The fluorescence signal of 1 and 2 is changed by less than 5 % by pH values in the range of 6.8 to 8.8. Thus, 1 and 2 are capable fluorescent tools to determine extracellular K+ levels by fluorescence enhancements at wavelengths higher than 500 nm.
Experimental Investigation on the Correlation between the Physicochemical Properties and Catalytic Activity of Six DESs in the Kabachnik‐Fields Reaction
Authors: Shaibuna M. , Sreekumar K. 
Published: November 2020

AbstractSix Type IV Deep Eutectic Solvents (homogeneous mixture of metal chloride hydrate and hydrogen bond donor) were prepared from ZrOCl2 ⋅ 8H2O/CeCl3 ⋅ 7H2O with urea, ethylene glycol and glycerol. A study was performed by correlating the properties of DESs with their activity as catalyst as well as reaction medium in Kabachnik‐Fields reaction. Among the six DESs, lower density, viscosity and higher acidity were observed for DES 1(Deep Eutectic Solvent developed from ZrOCl2.8H2O and urea at 1 : 5 ratio) and is reported as an excellent catalyst and reaction medium for the productive synthesis of α‐aminophosphonates within a short period of time. The wide substrate applicability was checked by synthesising 21 different α‐aminophosphonate derivatives and analysed by TLC, GCMS, 1HNMR, 13CNMR, and melting point measurements. One pot reaction of an aldehyde, dimethyl phosphite and amine (Kabachnik‐Fields/ Phospha‐Mannich reaction) took place at room temperature to give the corresponding α‐aminophosphonates in good yield and the precipitation of these products in to water avoided the regular work up process. Catalyst was recycled up to five times without any loss in its activity.
Asymmetric Synthesis of Catechol Pyran Isolated from Plectranthus sylvestris by δ‐Hydroxyalkynone Rearrangement
Authors: Fernandes Rodney A. , Saini Deepak 
Published: November 2020

AbstractA highly efficient atom‐economic and metal‐free rearrangement of δ‐hydroxyalkynone to 2,3‐dihydro‐4H‐pyran‐4‐one‐based strategy has been employed in the stereoselective total synthesis of either enantiomers of catechol pyran natural product isolated from Plectranthus sylvestris. The desired δ‐hydroxyalkynone substrates for rearrangement were prepared via the enantioselective Jacobsen kinetic resolution and the rearrangement was effected with cheaply available Brønsted acid para‐toluene sulfonic acid (p‐TsOH at 10 mol%). The strategy is concise and easily adoptable for synthesis of various 4‐hydroxy or 4‐keto‐2,6‐disubstituted pyran‐based natural products.
App recommendation based on both quality and security

Published: November 2020

AbstractWith the rapid prevalence of smartphones and the dramatic proliferation of mobile applications, people tend to do everything at their fingertips, including some sensitive activities, such as bank transfers. This makes security become one important factor when recommending apps to users. However, most existing methods recommend apps only on the basis of the apps' functionalities. Even when some methods take security into account, they usually roughly group apps with functionalities and identify the products using extra permissions as risky, but this ignores a common phenomenon that these permissions may be used only to achieve the corresponding functionalities. In this paper, we propose an app recommendation method considering both functionalities and security. For functionalities, we summarized them from app descriptions and further evaluated their completion quality in different products by analyzing their related reviews. For security, we cluster apps with similar functionalities and quality and analyze the permissions of apps in a more comparable range. In this way, our method recommends apps with higher completion quality of functionalities and security degree to users according to their demands. We conducted experiments on apps collected from six categories of Google Play, and the results show that our method has a good recommendation effect.
Financial development and top income shares in OECD countries

Published: November 2020

AbstractWe examine the causal impact of financial development (FD) on top income shares for a panel of 14 OECD countries—five Anglo‐Saxon countries, eight continental European countries, and Japan—over a 110‐year period. In our main General Method of Moments estimates, we find that a 1‐percentage‐point change in FD increases the top 1% income share by 0.2%. In distribution terms, a 1‐SD incr=ease in FD increases the top 1% income share by around 0.4 of an SD. The effects are robust to various measures of top income shares and FD and alternative estimation techniques, including nonparametric estimation. FD is typically viewed in positive terms in that it makes it easier to access credit and facilitates economic growth. Our results are important because they contribute to understanding of the potential negative effects of FD.
China's emerging businesses: The next generation of global corporations?
Authors: Atherton Andrew 
Published: November 2020

AbstractA growing number of Chinese businesses that are not well known outside China are going global, taking market share from incumbents worldwide. These businesses sustain rapid to hyper‐growth over considerable periods, allowing them to scale up quickly. They have strong market share in the domestic Chinese market, which serves as a platform for internationalization. Their strategies for entering new markets derive from their domestic business models, which they have been able to adapt to conditions in other countries. These businesses represent a fast‐growing cohort of emerging global corporations that will be major international competitors in the near future. This article helps businesses and analysts to identify China's emerging businesses. It offers insight into their strategies for growth and emergence.

AbstractIn this paper we present a unified approach to investigate existence and concentration of positive solutions for the following class of quasilinear Schrödinger equations,$$-\varepsilon^2\Delta u+V(x)u\mp\varepsilon^{2+\gamma}u\Delta u^2=h(u),\ \ x\in \mathbb{R}^N, $$-ε2Δu+V(x)u∓ε2+γuΔu2=h(u),x∈RN,where$$N\geqslant3, \varepsilon > 0, V(x)$$N⩾3,ε>0,V(x)is a positive external potential,his a real function with subcritical or critical growth. The problem is quite sensitive to the sign changing of the quasilinear term as well as to the presence of the parameter$$\gamma>0$$γ>0. Nevertheless, by means of perturbation type techniques, we establish the existence of a positive solution$$u_{\varepsilon,\gamma}$$uε,γconcentrating, as$$\varepsilon\rightarrow 0$$ε→0, around minima points of the potential.

Authors: Eggers Carsten , Wellach Ingmar , Groppa Sergiu , Strothjohann Martin , Klucken Jochen 
Published: November 2020

ZusammenfassungDie Parkinson-Krankheit als chronische neurodegenerative Erkrankung bedarf eines engen Zusammenspiels verschiedener Fachdisziplinen, um eine bestmögliche Lebensqualität der Patienten zu gewährleisten. Ein immer wieder identifiziertes Problem ist die insuffiziente Kommunikation zwischen den Protagonisten (z. B. „caregiver“, Ärzte und Therapeuten), insbesondere an den Sektorengrenzen. Die aktuellen Prozess- und Versorgungsketten der Parkinson-Krankheit bilden aber auch aufgrund struktureller Hürden bisher keine gelungene sektorenübergreifende Versorgung ab. Vor dem Hintergrund des neuen Digitale-Versorgung-Gesetzes (DVG) und den damit erstmalig rückfinanzierten, digitalen Gesundheitsanwendungen (DiGAs) können sich nun erstmals innovative, digitale Versorgungs- und Kommunikationsstrukturen etablieren und haben das Potenzial, damit die Versorgung chronischer Erkrankungen, wie z. B. der Parkinson-Krankheit, umfassend zu verändern. Beispiele und Anwendungsszenarien werden in diesem Übersichtsartikel vorgestellt sowie kritisch diskutiert.
First-Order Shape Derivative of the Energy for Elastic Plates with Rigid Inclusions and Interfacial Cracks
Authors: Rudoy Evgeny , Shcherbakov Viktor 
Published: November 2020

AbstractWithin the framework of Kirchhoff–Love plate theory, we analyze a variational model for elastic plates with rigid inclusions and interfacial cracks. The main feature of the model is a fully coupled nonpenetration condition that involves both the normal component of the longitudinal displacements and the normal derivative of the transverse deflection of the crack faces. Without making any artificial assumptions on the crack geometry and shape variation, we prove that the first-order shape derivative of the potential deformation energy is well defined and provide an explicit representation for it. The result is applied to derive the Griffith formula for the energy release rate associated with crack extension.
Maladaptive Schemata und berufliche Gratifikationskrisen bei ÄrztInnen und PsychotherapeutInnen
Authors: Kempf Maximilian , Jerg-Bretzke Lucia , Jarczok Marc N. , Beschoner Petra 
Published: November 2020

Zusammenfassung
Hintergrund
Laut Studienlage leiden ÄrztInnen häufig an Arbeitsstress und Burn-out. Gründe dafür liegen v. a. in den Arbeitsbedingungen. Daneben spielen „intrinsische“ Faktoren eine Rolle. Frühe maladaptive Schemata (MS) können als Marker für intrinsische Belastungen dienen. Ein Schema umfasst dauerhafte, ungünstige Muster von Gefühlen, Gedanken und Erinnerungen, die das Verhalten in einer konkreten Situation steuern. Der Beitrag soll eine systematische Übersicht über die internationale Studienlage zu Gratifikationskrisen und MS bei ÄrztInnen/PsychotherapeutInnen (PT) geben.

Material und Methoden
Systematische Literaturrecherche von 2000 bis 2020 in PubMed, Psyndex und Google Scholar. Eine Registrierung erfolgte bei OSF-Registries (osf.io/jxhga/). Suchbegriffe waren: „schema“, „maladaptive schema“, kombiniert mit „physician“, „psychiatrist“, „psychotherapist“, „psychologist“, als weitere Suche verknüpft mit „effort reward (imbalance)“ bzw. „effort-reward (imbalance)“.

Ergebnisse
In der ersten Suche wurden 906 Publikationen, in der zweiten 1088 Veröffentlichungen gefunden. Durch Filtern von Duplikaten, Screening von Abstracts und Inhalten dezimierte sich die Zahl auf 2 Publikationen. Mithilfe vor- und rückwärts gerichteter Suche wurden 5 weitere Arbeiten und damit insgesamt 7 relevante Publikationen identifiziert.

Schlussfolgerung
Bislang gibt es wenige Untersuchungen, die sich mit MS im Zusammenhang mit beruflichem Stress und mentaler Gesundheit bei ÄrztInnen/PT beschäftigen. Insbesondere das vielschichtige Konzept der Schemata erscheint aussagekräftiger als eher eindimensionale Persönlichkeitszüge. Intrinsische Faktoren haben eine große Bedeutung, wenn es um die Entwicklung von Präventions- und Hilfsmaßnahmen für belastete ÄrztInnen/PT geht.
Laparoscopic surgery for splenic injuries in the era of non-operative management: current status and future perspectives

Published: November 2020

AbstractThe spleen is one of the organs most commonly injured by blunt abdominal trauma. It plays an important role in immune response to infections, especially those sustained by encapsulated bacteria. Nonoperative management (NOM), comprising clinical and radiological observation with or without angioembolization, is the treatment of choice for traumatic splenic injury in patients who are hemodynamically stable. However, this strategy carries a risk of failure, especially for high-grade injuries. No clear predictors of failure have been identified, but minimally invasive surgery for splenic injury is gaining popularity. Laparoscopic surgery has been proposed as an alternative to open surgery for hemodynamically stable patients who require surgery, such as after failed NOM. We reviewed research articles on laparoscopic surgery for hemodynamically stable patients with splenic trauma to explore the current knowledge about this topic. After presenting an overview of the treatments for splenic trauma and the immunological function of the spleen, we try to identify the future indications for laparoscopic surgery in the era of NOM.

Published: November 2020

Abstract
Objectives
An optimized oral health-related section and a video training were developed and validated for the interRAI suite of instruments. The latter is completed by professional non-dental caregivers and used in more than 40 countries to assess care needs of older adults.

Methods
The optimized oral health–related section (ohr-interRAI) consists of nine items and a video training that were developed in consecutive phases. To evaluate psychometric properties, a study was conducted in 260 long-term care residents. Each resident was assessed by a dentist and by four caregivers (two who received the video training, two who did not).

Results
Mean kappa values and percent agreement between caregivers and dentist ranged between κ = 0.60 (80.2%) for dry mouth and κ = 0.13 (54.0%) for oral hygiene. The highest inter-caregiver agreement was found for dry mouth with κ = 0.63 [95% CI: 0.56–0.70] (81.6%), while for the item palate/lips/cheeks only κ = 0.27 [95% CI: 0.18–0.36] (76.7%) was achieved. Intra-caregiver agreement ranged between κ = 0.93 [95% CI: 0.79–1.00] (96.4%) for dry mouth and κ = 0.45 [95% CI: 0.06-0.84] (82.8%) for gums. Logistic regression analysis showed only small differences between caregivers who watched the video training and those who did not.

Conclusions
Psychometric properties of the optimized ohr-interRAI section were improved compared to previous versions. Nevertheless, particularly the items based on inspection of the mouth require further refinement and caregiver training needs to be improved.

Clinical Relevance
Valid assessment of oral health by professional caregivers is essential due to the impaired accessibility of regular dental care for care-dependent older adults.

AbstractThe pollen beetle Brassicogethes aeneus is a serious pest of oilseed rape (Brassica napus) in Europe. Management of this pest has grown difficult due to B. aeneus’s development of resistance to pyrethroid insecticides, as well as the pressure to establish control strategies that minimise the impact on nontarget organisms. RNA interference represents a nucleotide sequence-based, and thus potentially species-specific, approach to agricultural pest control. The present study examined the efficacy of targeting the coatomer gene coatomer subunit alpha (αCOP), via both microinjection and dietary exposure to exogenous complementary dsRNA, on αCOP-silencing and subsequent mortality in B. aeneus. Beetles injected with dsRNA targeting αCOP (at 0.14 µg/mg) showed 88% and 100% mortality at 6 and 10 days post-injection, respectively; where by the same time after dietary exposure, 43%–89% mortality was observed in the 3 µg dsRNA/µL treatment, though the effect was concentration-dependent. Thus, the effect was significant for both delivery routes. In working towards RNA-based management of B. aeneus, future studies should include αCOP as a target of interest.
Effects of hydroxycinnamic acid esters on sweetpotato weevil feeding and oviposition and interactions with Bacillus thuringiensis proteins

Published: November 2020

AbstractSweetpotato weevil (SPW) pest management is challenging because the pest target is sub-terranean, so the application of pesticides is impractical and usually ineffective. Host plant resistance and the genetic transformation of sweetpotatoes to produce entomotoxic Bt proteins offer potential for environmentally benign pest control. Resistance can be conferred by naturally occurring hydroxycinnamic acids which protect against oviposition by adults, but these compounds are restricted to the root surface so do not protect against the cortex bound larvae where the greatest damage occurs. Resistance could be enhanced if combined with expression of Bt proteins in transformed plants, but interactions between hydroxycinnamic acids and Bt proteins remain unknown. Here the bioactivity of Cry7Aa1 protein and hydroxycinnamic acid esters was evaluated individually and in combination against SPW larvae and mortality determined. Low and high concentrations of hydroxycinnamic acid esters alone caused significantly higher mortality of both weevil species in all experiments compared to the control. SPW larval mortality was greater when tested as a combination of hydroxycinnamic acid esters and Bt protein, but this effect was additive not synergistic. Although we report no evidence of antagonistic interactions, the antifeedant effects of the plant compounds conferring host plant resistance could have reduced consumption of the Bt protein in our assays leading to a lower efficacy when combined. Further work is required to determine whether the toxic effects of Bt proteins function alongside host plant resistance in sweetpotato under field conditions.
The impact of wearable cardioverter-defibrillator use on long-term decision for implantation of a cardioverter-defibrillator in a semirural acute care hospital
Authors: Sinha Anil-Martin , Bense Jens , Hohenforst-Schmidt Wolfgang 
Published: November 2020

Abstract
Purpose
Large-scale multi-center studies have reported on efficacy of the wearable cardioverter-defibrillator (WCD). However, outcomes focused on WCD patients treated at community-based acute care centers are lacking.

Methods
Patients with cardiomyopathy were included when left ventricular ejection fraction (LVEF) at baseline was ≤ 35%. There were 120 patients meeting the criteria who also had LVEF measured at baseline and after 90 days of WCD use.

Results
After 90 days of WCD use, there were 44 (37%) patients in whom LVEF improved to > 35%. Comparison of patients, by whether LVEF improved or not, indicated that median days of WCD wear and hours of daily use were similar as well as characteristics, such as gender, age, and starting LVEF; and diagnoses leading to WCD prescription were similar between groups as were symptom-based prescription of medications. At the end of WCD use, improved LVEF > 35% correlated with fewer implantable cardioverter-defibrillator (ICD) implants. There were 4 (3%) episodes of new atrial fibrillation detected during WCD use. The WCD appropriately delivered a shock to 3 (2.5%) patients with VT/VF being terminated by the first shock. All shocked patients survived for at least 24 h post-shock.

Conclusions
During WCD use, ischemic and non-ischemic cardiomyopathy patients manifest improved LVEF by 90 days. Long-term care decisions, such as implantation of an ICD, were influenced by LVEF improvement and occurrence of spontaneous VT/VF. The WCD protected patients from sudden cardiac death (SCD) until patient response to guideline-directed medical therapy could be determined.
