The Role of Temperature in the Stress–Strain Evolution of Alpine Rock-Slopes: Thermo-Mechanical Modelling of the Cimaganda Rockslide
Authors: Morcioni Andrea , Apuani Tiziana , Cecinato Francesco 
Published: February 2022

AbstractIn this work, the thermo-mechanical stress–strain history of an Alpine slope is analyzed, with particular focus on the historical Cimaganda large landslide (Sondrio Province, Italy), which mobilized an estimated volume of 7.5 mm3 of rock material. Accurate geomorphological and geomechanical characterization involving field surveys and laboratory testing was carried out, leading to the development of a conceptual model of the slope. A thermo-mechanical semi-coupled approach was developed, considering both glacial debuttressing and thermo-mechanical effects due to gradual exposure of the slope to atmospheric conditions and paleo-temperature redistribution resulting from the Last Glacial Maximum deglaciation. A 2D distinct-element numerical approach was adopted, supported by a 2D finite-element analysis to simulate heat diffusion over the Valley cross-section. Modelling results allow to simulate the general evolution of the Cimaganda rock-slope and to highlight the significance of thermal processes in preparing rock-slope instabilities. While the mechanical effect of ice thickness reduction alone brings about moderate rock mass damage, the introduction of temperature couplings results in a substantial increase of damage, representing a significant factor controlling the stress–strain evolution of the slope. Simulated displacement and the development of a deep region of shear strain localization at a depth roughly corresponding to that of the detected Cimaganda sliding surface, allow to highlight the significance of temperature influence in preparing the rock-slope to instability.

Zusammenfassung
Hintergrund
Komplexe Wundsituationen stellen Patient und Therapeut häufig vor eine große Herausforderung. Neben der Behandlung der ursächlichen Erkrankung ist die Lokaltherapie bei der Wundbehandlung essenziell. Neben den klassischen Wundauflagen stehen mittlerweile mit Nanomaterialien neue Optionen zur Verfügung.

Fragestellung
Die vorliegende Studie untersucht den Einfluss von Nanogen Aktiv (Vertrieb Lamed, Oberhaching, Deutschland) auf die Wundheilung und erfasst die Patientenzufriedenheit am Ende der Behandlung.

Material und Methoden
In der prospektiven Single-Center-Studie wurden im Zeitraum von 02/18 bis 04/20 insgesamt 20 Patienten mit chronischen Wunden mit Nanogen Aktiv behandelt. Hierzu wurden demografische Daten, das Keimspektrum in den Wunden und klinische Verläufe erfasst und ausgewertet.

Ergebnisse
In sieben Fällen (7/20) konnte eine Reduktion der Wundfläche in 4–40 Wochen erreicht werden. Bei den übrigen 13 Patienten konnte aus verschiedenen Gründen kein Therapieerfolg erzielt werden.

Diskussion
Nanogen Aktiv kann einen positiven Effekt auf die Heilung komplexer Wunden haben. Größe und Tiefe der Wunde beeinflussen die Therapiedauer. Die zugrunde liegende Erkrankung muss zwingend mitbehandelt werden. Die Indikation zur Behandlung mit Nanogen Aktiv sollte aufgrund des hohen zeitlichen Aufwandes individuell gestellt werden.

AbstractLow-level laser therapy (LLLT) has been a treatment modality by many androgenetic alopecia (AGA) patients in recent years. It remained unclear as to how long the treatment regime should be maintained, and which characteristics of patients should this be recommended. A real-world study was carried out with an FDA-cleared low-level laser helmet for 1383 patients. Ordinal logistic regression analysis with propensity score matching (PSM) was used to investigate the factors related to efficacy assessment. More than 80% of users were between 18 and 40 years old. The median use times were 133 for mild AGA patients and 142 for moderate-to-severe AGA patients, which equated to 38 weeks and 40 weeks, respectively. The overall clinical effectiveness was nearly 80%. PSM analysis revealed that gender (P = 0.002), use period (P = 0.068), scalp conditions with dandruff, rash, and itchy symptoms were associated with the grading of efficacy assessment. Male users (ordinal OR: 1.35, CI: (1.01, 1.79)); use for more than 180 times or use period for 1 year (ordinal OR: 1.40, CI: (1.11, 1.96)); and those with scalp dandruff (ordinal OR: 1.34, CI: (1.01, 1.87)), rash (ordinal OR: 1.47, CI: (1.04, 2.07)), and itchy symptoms (ordinal OR: 1.51, CI: (1.12, 2.03)) had better efficacy assessments. The recommended treatment regime with low-level laser helmet was more than 1 year or 180 use times. Male patients with dandruff, rash, and itchy symptoms in scalps tended to have a better efficacy assessment.
The Average Condition Number of Most Tensor Rank Decomposition Problems is Infinite
Authors: Beltrán Carlos , Breiding Paul , Vannieuwenhoven Nick 
Published: February 2022

AbstractThe tensor rank decomposition, or canonical polyadic decomposition, is the decomposition of a tensor into a sum of rank-1 tensors. The condition number of the tensor rank decomposition measures the sensitivity of the rank-1 summands with respect to structured perturbations. Those are perturbations preserving the rank of the tensor that is decomposed. On the other hand, the angular condition number measures the perturbations of the rank-1 summands up to scaling. We show for random rank-2 tensors that the expected value of the condition number is infinite for a wide range of choices of the density. Under a mild additional assumption, we show that the same is true for most higher ranks$$r\ge 3$$r≥3as well. In fact, as the dimensions of the tensor tend to infinity, asymptotically all ranks are covered by our analysis. On the contrary, we show that rank-2 tensors have finite expected angular condition number. Based on numerical experiments, we conjecture that this could also be true for higher ranks. Our results underline the high computational complexity of computing tensor rank decompositions. We discuss consequences of our results for algorithm design and for testing algorithms computing tensor rank decompositions.
Inscription and Intergenerational Connection in Arthur Ransome’s Lakeland Novels
Authors: Lustig Timothy John 
Published: February 2022

AbstractJacqueline Rose’s influential notion of the “impossibility” of children’s literature rests on the claim that such works “frame” the child and place the adult “first”. Although Ransome’s writings undoubtedly contain instances of such divisions and hierarchies, this article argues that they also explore various kinds of communication and connection. In particular, the Lakeland novels which are the focus here—Swallows and Amazons (1930/2012), Swallowdale (1931/1968), Winter Holiday (1933/2013), Pigeon Post (1936/2013) and The Picts and the Martyrs (1943/1993)—make frequent mention of literary works but also display an intense interest in messages which are written on paper but also cut into surfaces such as wood and stone. These inscriptions challenge generational hierarchies in that they establish a means for different individuals to communicate the experience of being in the same place, albeit at different times. Yet as well as conveying the excitements of discovery and exploring the consolations which can follow recognitions of belatedness, this article also argues that Ransome’s Lakeland novels acknowledge and seek to manage the losses experienced by each generation.
The impact of lecture capture availability on academic performance in a large biomedical science course

Published: February 2022

AbstractLecture capture is a technology where live lectures are recorded in a digital format and made available to students to view at their convenience. The use of this technology in higher education has steadily increased despite mixed results as to whether it is beneficial to student achievement. The current study utilized a two-group quasi-experimental design to examine the impact of lecture capture availability on academic performance in a large enrollment, two-term, second year biomedical science course. Academic performance was compared between two matched cohorts enrolled in the same biomedical science course taught by the same instructor in which one course did not have access to lecture recordings (2017–18 academic year, N = 433) and the other did (2018–19 academic year, N = 414). Academic performance was evaluated by comparing scores on identical exam questions and the final grade earned in the course. Student’s t-test revealed that lecture capture availability resulted in a decline in performance on exams and the final course grade. We also evaluated whether lecture capture influenced student attendance via an in-class student response system and a t-test found that student attendance was comparable between the cohorts. A chi-squared test also found that lecture capture availability resulted in significantly more course failures. Importantly, a student’s t-test showed that GPA did not differ between the cohorts. To our knowledge this is the first study to show that lecture capture availability resulted in a decline in academic performance despite similar in-class attendance and GPA.
The Effects of Emotion Regulation Treatment on Disruptive Behavior Problems in Children: A Randomized Controlled Trial

Published: February 2022

AbstractDisruptive behavior problems are a frequent reason for children’s referrals to psychological services and can have negative effects on social and academic functioning. Most treatment programs involve parents as recipients and implementation of intervention programs in school is low. Deficits in emotion regulation have recently been implicated in the development of disruptive behavior disorders, making child directed early intervention programs focusing on increasing emotion regulation skills feasible. The purpose of this study was to assess the effects of Tuning Your Temper, a brief cognitive behavioral program for children with disruptive behavior problems, in a randomized controlled trial. A total of 125 children with disruptive behavior problems at school, aged 6–11 years old were randomized to either intervention or wait-list control condition. Treatment was conducted at school. Assessments included teacher and parent ratings on the Strengths and Difficulties Questionnaire (SDQ) and the Disruptive Behavior Rating Scale (DBRS) pre- and post-treatment and at 6-month follow-up. Results showed a significant reduction in behavior problems for the treatment condition on both measures and effects were maintained at 6-month follow-up. Results were more robust for teacher ratings, with medium to large effect sizes. Tuning Your Temper appears to be a promising early intervention program for children with disruptive behavior problems at school.

Published: February 2022

AbstractDiffusion of oxygen and nitrogen in the cold sprayed commercially pure Ti (CS CP Ti) deposits profoundly impacts their mechanical properties. One plausible approach to additively manufacture a malleable (wrought) and high-density Ti is optimizing CS deposition parameters considering a reduction in porosity for the following heat treatment. Herein, we examined porosity, bulk density, and hardness characteristics of CS CP Ti deposits produced at varying processing gas temperatures (700, 800, and 900°C), which significantly influences the interactions of CP Ti with oxygen and nitrogen. Post-processing heat treatments at 800, 900, and 1000°C were performed in a high vacuum furnace, respectively, which diminished splat boundaries and submicron pores with increasing grain size. SEM images revealed that CS CP Ti had a dense microstructure with low porosity. According to LECO research, low spraying temperatures (i.e. 700°C) maintained oxygen and nitrogen levels in the CS CP Ti deposits at the same level as the stock powders. The bulk density of CS CP Ti produced at 900 °C matched that of wrought CP Ti metal. In addition, to improve the mechanical properties of CS CP Ti deposits, we looked at the link between CS conditions and heat treatment.
Epistemic Contradictions Do Not Threaten Classical Logic
Authors: Mayr Philipp 
Published: February 2022

AbstractEpistemic contradictions are now a well-known and often discussed phenomenon among those who study epistemic modals. These contradictions are expressed by sentences like ‘It is raining and it might not be raining’ whose oddness to the common ear demands an explanation. However, it has turned out to be a rather controversial enterprise to provide such an explanation in a sufficiently precise and general manner. According to pragmatic explanations, epistemic contradictions are semantically consistent but pragmatically defective. According to semantic explanations, one should regard epistemic contradictions as plain semantic inconsistencies. Endorsing such a semantic solution is, however, tantamount to rejecting classical logic, which predicts the consistency of epistemic contradictions. After arguing that all existing solutions to this problem face as yet unmet challenges, I will present a new solution that adequately overcomes these challenges. I will propose to view epistemic contradictions as semantically consistent but epistemically defective sentences. The main thesis emerging will be that we need neither abandon the inference rules of classical logic nor the classical truth-conditional approach to semantics to deal adequately with epistemic contradictions.
Less Screen Time, More Frequent Fruit and Vegetable Intake and Physical Activity are Associated with Greater Mental Wellbeing in Adolescents

Published: February 2022

AbstractWellbeing declines during adolescence, for which the reasons are unclear. This analysis explored associations between wellbeing and multiple lifestyle, socioeconomic and school-level factors in young people. Data were collected as part of the Wellbeing in School (WiSe) survey of adolescent school children in Northern Ireland at age 13–14 years (N = 1618; 49% female) and 15–16 years (N = 1558; 50.5% female). Wellbeing was assessed using the short-form Warwick-Edinburgh Mental Wellbeing Scale (sWEMWBS), where scores declined between time one (13–14 years) and time two (15–16 years) in both sexes and were significantly lower in females at both timepoints. Multilevel, multivariate modelling was therefore undertaken separately for males and females with sWEMWBS scores as the dependent variable. Physical activity, family affluence, fruit and vegetable intake, social media use, sleep duration, school factors (size and type) and religion were independent variables. More frequent physical activity in both sexes at both timepoints was associated with higher sWEMWBS scores. In females, higher sWEMWBS scores were associated with less social media use at time one (and marginally at time two), greater family affluence at time two, and being Catholic at both timepoints. In males, higher sWEMWBS scores were associated with more frequent fruit and vegetable intake at time one. Mental wellbeing was unrelated to sleep duration or school factors in either sex, at both time points. Efforts to maximize mental wellbeing in adolescents should promote engagement in physical activity and implement sex-specific interventions.
Non-degeneracy of Positive Solutions for Fractional Kirchhoff Problems: High Dimensional Cases
Authors: Yang Zhipeng 
Published: February 2022

AbstractIn this paper, we establish the nondegeneracy of positive solutions to the fractional Kirchhoff problem$$\begin{aligned} \Big (a+b{\int _{\mathbb {R}^{N}}}|(-\Delta )^{\frac{s}{2}}u|^2\mathrm{{d}}x\Big )(-\Delta )^su+u=u^p,\quad \text {in}\ \mathbb {R}^{N}, \end{aligned}$$(a+b∫RN|(-Δ)s2u|2dx)(-Δ)su+u=up,inRN,where$$a,b>0$$a,b>0,$$0<s<1$$0<s<1,$$1<p<\frac{N+2s}{N-2s}$$1<p<N+2sN-2sand$$(-\Delta )^s$$(-Δ)sis the fractional Laplacian. In particular, we prove that uniqueness breaks down for dimensions$$N>4s$$N>4s, i.e., we show that there exist two non-degenerate positive solutions which seem to be completely different from the result of the fractional Schrödinger equation or the low dimensional fractional Kirchhoff equation. As one application, combining this nondegeneracy result and Lyapunov-Schmidt reduction method, we can derive the existence of solutions to the singularly perturbation problems.
Feasibility of lime and biopolymer treatment for soft clay improvement: a comparative and complementary approach

Published: February 2022

AbstractHighway pavement infrastructure projects which involve soil improvement should be executed, ensuring environmental sustainability. In the present study, guar gum (GG) and lime were assessed for the purpose of soft clay stabilization. The experimental program for the soil stabilization employed a two-stage process. The initial stage involves treatment of the soil with various percentages of lime (3, 5, 7, and 9%) and GG (0.6, 1.0, 1.4, and 1.8%), maintaining the same material acquisition cost and considering curing (0, 7, 14, and 28 days) for the unconfined compressive strength (UCS). In the second experimental stage, a complementary approach in which 3% lime was combined with GG at various percentages (0.1, 0.2, and 0.3%) was employed. The tests conducted include UCS, California bearing ratio (CBR), and strength loss resistance (SLR). Results show that the sole use of lime and GG resulted in significant improvement in the UCS, albeit lime was better. While UCS improved with curing time for the lime-stabilized soil, UCS gain for GG occurred only for up to 7 days curing because biodegradation of GG by microbes in the soil ensues on further curing. Lime-GG stabilization resulted in better UCS and CBR improvement with curing than lime stabilization; however, lime stabilization yielded better SLR. The optimum additive content for strength improvement was obtained at 3% lime + 0.3% GG. Microstructural analysis indicated cementation in the stabilized soil. Predictive models for the UCS were developed based on regression methods. Model evaluation revealed that Gaussian process model provided the best UCS prediction.
Impact and distributional effects of a home garden and nutrition intervention in Cambodia

Published: February 2022

AbstractHome garden interventions combining training in agriculture and nutrition have the potential to increase vegetable production and consumption in lower-income countries, but there remains a need for better evidence for impact. This study contributes to filling this gap by evaluating the impact and distributional effects of a home garden intervention in Cambodia. We used a cluster randomized controlled trial with before and after data for a sample of 500 rural households with children under five and women 16–49 years old. Impact was estimated using analysis of covariance (ANCOVA) and conditional quantile regressions with non-parametric bounds. The results show that the intervention significantly increased the adoption of nearly all promoted gardening methods. More households (+ 35%; p < 0.01) produced vegetables, and the production period was extended by five months on average. One-month recall data show an increase in vegetables harvested (+ 25 kg; p < 0.01) and consumed (+ 10 kg; p < 0.01) from the garden. Quantile regressions confirm these findings and show that nearly all households benefitted, but households that were already doing better at baseline tended to benefit more. Seven-day recall data show an increase in the quantity of vegetables consumed (+ 61 g/day/capita; p < 0.01) and an increased quantity of vitamin A, folate, iron, and zinc contained in these vegetables. Women contributed more to the garden work than men and their time spent in the garden increased by 29 min/day on average. These results add further evidence that integrated home garden interventions can contribute to nutrition outcomes and that almost all participants can benefit.

Published: February 2022

Abstract
Purpose
Scabies is a World Health Organization-defined neglected tropical disease and a growing public health issue worldwide. It is difficult to obtain reliable data on prevalence due to the lack of standardized tests. The aim of this study was to assess scabies online search behavior in Germany to identify local differences using Google search volume.

Methods
Google Ads Keyword Planner was used to investigate the scabies-related search volume for Germany as a whole, its 16 federal states, and 15 large cities for the period from January 2016 to December 2019. The identified search terms were qualitatively categorized and critically analyzed.

Results
A total of 572 keywords with an overall search volume of 11,414,180 searches regarding scabies were identified in Germany. The number of searches was higher in winter than in summer, with a national peak in March 2018. Around 30.6% of the searches regarding scabies therapy (n = 978,420) were related to home remedies. Regarding body localization, most searches focused on the whole body (n = 109,050), followed by head (n = 89,360) and the genital area (n = 28,640).

Conclusions
The analysis of Google search data provides an overview of the populations’ interest regarding scabies. The analysis can detect local peaks and assess the relevance of scabies at individual localizations of the body. The study highlighted current possible shortcomings in the therapy of scabies. It also underlined the importance of improving awareness regarding scabies so that affected individuals can consult a doctor earlier for treatment.

Published: February 2022

AbstractStock movement prediction is a challenging problem to analyze in both academic and financial research areas. The advancement of deep learning (DL) techniques has grasped the attention of researchers to employ them for predicting the stock market’s future trends. Few frameworks can understand the financial terms in literature, and the volatile nature of stock markets further complicates this process. This paper has tried to overcome the existing challenges by introducing a DL-based framework using financial news articles to forecast the stock market. After performing preprocessing step, the deep contextualized word representation (DCWR) approach is applied for feature extraction. In the next step, the independent component analysis (ICA) method is used for feature reduction. Finally, the resultant features train the hierarchical attention networks (HANet) classifier to predict the stock movements. The proposed scheme is evaluated over the 7 years of data from a publicly available dataset gathered from the Reuter’s website and attained an average prediction accuracy of 92.5% which shows our framework’s robustness.
