U–Pb zircon dating of the Paleoproterozoic khondalite series in the northeastern Helanshan region and its geological significance
Authors: Li Liming , Yang Fanyan , Li Mingtao , Liang Zhirong , Ma Xuedong , Tian Jingxiong 
Published: June 2022

Abstract
Petrography, zircon cathodoluminescence, and laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS) U–Pb zircon dating were performed on the Paleoproterozoic khondalite series and the intrusive altered diabase dykes developed in the northeastern Helanshan region were analyzed. The results showed that most of the zircons in the khondalite series were detrital zircons with oscillatory zoning and a high Th/U ratio, with few metamorphic zircons having a low Th/U ratio. The 207Pb/206Pb age of the detrital zircons ranged from 3131–1980 Ma, which constrained the protolith age of the Helanshan khondalite series to after 1980 Ma. The age of the metamorphic zircons indicated two age groups as follows: 1965–1921 Ma and 1876–1820 Ma. Besides, the age of altered diabase dykes was 1865–1850 Ma. In combination with previous studies, these new metamorphic ages indicated that the metamorphic events in the northeastern Helanshan region involved the collision followed by post-collisional extension and exhumation between the Yinshan Block to the north and the Ordos Block to the south. Moreover, the 1965–1921 Ma group represented the period of the collision between the Yinshan Block and the Ordos Block and the subsequent post-collisional extension event, whereas 1876–1820 Ma indicated the period of the exhumation stage.
Variable selection for bivariate interval-censored failure time data under linear transformation models

Published: June 2022

Abstract
Variable selection is needed and performed in almost every field and a large literature on it has been established, especially under the context of linear models or for complete data. Many authors have also investigated the variable selection problem for incomplete data such as right-censored failure time data. In this paper, we discuss variable selection when one faces bivariate interval-censored failure time data arising from a linear transformation model, for which it does not seem to exist an established procedure. For the problem, a penalized maximum likelihood approach is proposed and in particular, a novel Poisson-based EM algorithm is developed for the implementation. The oracle property of the proposed method is established, and the numerical studies suggest that the method works well for practical situations.
A quantile regression estimator for interval-censored data
Authors: Frumento Paolo 
Published: June 2022

Abstract
We describe an estimating equation that can be used to fit quantile regression models to interval-censored data. The proposed estimator presents important advantages over the existing methods, and can be applied when the data are a mixture of interval-censored, left-censored, and right-censored observations. We describe estimation and inference, report simulation results, and apply the proposed method to analyze the Signal Tandmobiel® data. The necessary R code has been incorporated in the existing R package

Hunting and water scarcity affect habitat occupancy by peccaries (Tayassu pecari and Pecari tajacu) in Calakmul, Mexico
Authors: Briceño-Méndez Marcos , Naranjo Eduardo J. , Altrichter Mariana , Contreras-Perera Yamili 
Published: June 2022

Abstract
The white-lipped peccary (WLP; Tayassu pecari) and the collared peccary (CP; Pecari tajacu) are social ungulates of huge ecological and economic importance. We determined the habitat occupancy for peccaries in a rural community bordering the Calakmul Biosphere Reserve in Campeche, Mexico. Twenty-eight stratified sampling points were randomly placed in the study area during a rainy and a dry season, where the presence of both peccary species was measured in relation to three ecological variables (habitat type, presence of natural predators, and water availability) and one anthropogenic variable (hunting). Ten sampling points were established with camera traps (total days/camera traps = 2268), and 18 sampling points were plots of 20 m2 to detect feces and/or footprints. To assess the relationship between both species’ presence and the selected variables, models of habitat occupancy were constructed using a binary matrix of detection/non-detection using the PRESENCE program. For WLP and CP, the respective estimated occupancy probabilities were 30 and 40% in the rainy season and 88 and 44% in the dry season. Our results suggest that occupancy by WLP is affected by habitat type and predators in the rainy season and by water availability and hunting in the dry season. Conversely, for CP, occupancy is affected by water availability and hunting in the rainy season, and by habitat type and predators in the dry season. Thus, hunting negatively affects the way that WLP occupy specific habitats, such as floodplain forest and medium sub-deciduous forest, particularly during periods of water scarcity when the species is more vulnerable to hunting.
“A Self-Portrait in Books” — Reflections on the Aphoristic Library of Elazar Benyoëtz
Authors: Kühne Jan , Schlechter Anna Rosa 
Published: June 2022

Abstract
This article focuses on trans-linguistic relationships between the German aphoristic writings of Israeli, Hebrew poet, and rabbi Elazar Benyoëtz (*1937) and his personal library, which is one of the last and largest private book collections in Israel to contain the German-Jewish literary canon. By reading traces from the library’s marginalia and paraphernalia, analyzed here for the first time, the article presents five case studies that sketch Benyoëtz’s transformation during the 1960s and 1970s from a Hebrew poet into the most influential contemporary writer of aphorisms in German. The article also presents points of departure for future research into the development of the Archiv Bibliographia Judaica, the largest encyclopedia of Jewish authors in the German language.

Published: June 2022

Abstract
Polyacrylonitrile (PAN) was often used as a composite fiber matrix due to its good spinning characteristics. Herein, photoluminescent quantum dot-doped nanofibers with tunable diameters were successfully prepared using electrospinning by adding CdSe/CdS quantum dots (QDs) in PAN spinning solution. The morphology and structure of CdSe/CdS-PAN nanofibers were characterized by scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR), and the mechanical and photoluminescent properties of CdSe/CdS-PAN nanofibers were investigated. Stable photoluminescent nanofibers were obtained owning to the improved stability of photoluminescent property of CdSe/CdS QDs in the PAN nanofiber. The stable photoluminescent CdSe/CdS-PAN nanofibers might be used for anti-fake labels, ultraviolet sensors, smart textiles and optoelectronic devices.

Published: June 2022

ABSTRACT
Sprinting is a key component for many individual and team sports. Therefore, to enhance sprint performance, various training methods are widely used by coaches and practitioners, including maximum sprint speed and resisted sprint training. Resisted sprinting with sled towing is a method that has recently received considerable attention from the sport science community. However, to date, no consensus exists regarding its acute and chronic effects in team sport athletes. This narrative review aimed to (a) review and analyze the mechanics of sprinting under unresisted and resisted conditions with a specific focus on team sport disciplines; (b) provide a thorough and applied discussion on the importance of considering acute and chronic effects of sled loading on technique, electromyographic activity, and force production, as well as on the role of muscle architecture and neural factors in sled training; (c) analyze the effects of increasing sled loads during acceleration and maximum velocity phases on contact and flight phases, while concomitantly examining kinetic, kinematic, and neuromuscular aspects, because all these factors affect each other and cannot be properly understood in isolation.

Published: June 2022

ABSTRACT
Exercise is an effective tool for managing and treating type II diabetes (T2DM) and may be a useful component of a diabetes management program. Both short- or long-term exercise interventions can improve physical fitness, metabolic health, and cardiovascular function in individuals with poor glycemic control. Incorporating aerobic and resistance exercise as part of a comprehensive diabetes management plan can play a vital role in the fight against this chronic metabolic disease. Progression and individualized exercise programming are critical for an effective and enjoyable exercise experience in a gym setting. With respect to safety, exercise professionals should be aware of special considerations and potential complications persons with T2DM can experience when exercising.

Surgical Treatment of Adult Williams-Beuren Syndrome with Pulmonary Arteriovenous Fistula
Authors: Zhang Xiaojie , Wang Shiqiang , Huang Gangping 
Published: June 2022

Williams-Beuren syndrome (WBS) is a genetic disease involving the gene deletion of a chromosome. It is sporadically caused by the disruption of the elastin gene at the locus 7q11.23, and it occurs in as many as 1:7,500 individuals [Zucker 2018].
WBS includes cardiac lesions and a wide spectrum of congenital malformations with cardiovascular disorders, representing the most worrisome ones. The most typically frequent cardiovascular anomalies primarily comprise supravalvular aortic stenosis, peripheral pulmonary stenosis, mitral regurgitation, and aortic coarctation [Matisoff 2015].
Other main features include central nervous system and connective tissue involvement, mainly with a characteristic elfin face, mental and growth retardation, and hypercalcemia. We report a rare case of WBS with right pulmonary arteriovenous fistula (PAVF), associated with supravalvular aortic membrane stenosis, mitral regurgitation, and aortic coarctation. The patient underwent two-stage surgical treatment with satisfactory results at 5 years of follow-up.
This case study was approved by the local research ethics board. Written informed consent was obtained from this patient.

OBJECTIVES
To determine whether maternal supplementation with high-dose docosahexaenoic acid (DHA) in breastfed, very preterm neonates improves neurodevelopmental outcomes at 18 to 22 months’ corrected age (CA).

METHODS
Planned follow-up of a randomized, double-blind, placebo-controlled, multicenter trial to compare neurodevelopmental outcomes in breastfed, preterm neonates born before 29 weeks’ gestational age (GA). Lactating mothers were randomized to receive either DHA-rich algae oil or a placebo within 72 hours of delivery until 36 weeks’ postmenstrual age. Neurodevelopmental outcomes were assessed with the Bayley Scales of Infant and Toddler Development third edition (Bayley-III) at 18 to 22 months’ CA. Planned subgroup analyses were conducted for GA (&lt;27 vs ≥27 weeks’ gestation) and sex.

RESULTS
Among the 528 children enrolled, 457 (86.6%) had outcomes available at 18 to 22 months’ CA (DHA, N = 234, placebo, N = 223). The mean differences in Bayley-III between children in the DHA and placebo groups were −0.07 (95% confidence interval [CI] −3.23 to 3.10, P = .97) for cognitive score, 2.36 (95% CI −1.14 to 5.87, P = .19) for language score, and 1.10 (95% CI −2.01 to 4.20, P = .49) for motor score. The association between treatment and the Bayley-III language score was modified by GA at birth (interaction P = .07). Neonates born &lt;27 weeks’ gestation exposed to DHA performed better on the Bayley-III language score, compared with the placebo group (mean difference 5.06, 95% CI 0.08–10.03, P = .05). There was no interaction between treatment group and sex.

CONCLUSIONS
Maternal DHA supplementation did not improve neurodevelopmental outcomes at 18 to 22 months’ CA in breastfed, preterm neonates, but subgroup analyses suggested a potential benefit for language in preterm neonates born before 27 weeks’ GA.
Social comparisons: A potential mechanism linking problematic social media use with depression
Authors: Samra Adele , Warburton Wayne A. , Collins Andrew M. 
Published: June 2022

Abstract

Background and aims
The majority of Australians are regular users of social media, especially young adults. Of concern, is that a minority of people appear to use social media in an addictive or problematic way which is associated with negative psychological outcomes such as depression. Social comparisons, where users compare themselves to others on social media, have also been linked with depression. Therefore, the key aim of the study was to determine whether social comparisons mediate the relationship between Problematic Social Media Use (PSMU) and depression.

Method
In a two-part study 144 participants (65 females) answered a series of self-report questions assessing factors relating to PSMU and then came into the lab to view a series of social media images, (pre-tested to be upward or downward comparisons).

Results
Females used social media more problematically, liked more upward than downward comparison images and compared themselves more negatively to others on social media than did males. Higher PSMU scores were associated with depression and low self-esteem and comparing oneself more negatively to others on social media. Finally, focusing on upward comparisons and a tendency to make negative comparisons to others on social media partially mediated the association between PSMU and depression.

Discussion and conclusions
Social comparisons may function as a mechanism linking PSMU with negative psychological outcomes. Clinical interventions for individuals with PSMU which reduce the focus on upward social comparisons may also reduce negative psychological outcomes such as depression.

Published: June 2022

In recent years, the popularity of herbal medicine has increased. Lemon balm (Melissa officinalis L.) is a perennial essential oil herb that has been used as a medicinal plant for more than 2 thousand years. It is known that the productivity of plants is directly related to their resistance to phytopathogens, in particular, micromycetes of the genus Fusarium. One of the main mechanisms of plant damage by phytopathogens is oxidative stress. Micromycetes of the genus Trichoderma and soil cyanobacteria (CB) occupy an important place among the natural antagonists of fungi of the genus Fusarium. The aim of the work was to study the state of the antioxidant system of Melissa officinalis L. plants when grown on substrates contaminated with the micromycete Fusarium culmorum and its antagonists – the cyanobacterium Fischerella muscicola and the micromycete Trichodеrma viride. It was found that the presence of the pathogenic micromycete F. culmorum in the soils for growing lemon balm for two months has a stressful effect on lemon balm plants: the intensity of lipid peroxidation, the content of phenolic compounds and the amount of antioxidants in the in plant leaves were significantly higher than in the control. At the same time, at elevated temperatures, the content of phenolic compounds increased, which may be due to increased metabolism and the level of oxidative stress. The introduction of microorganisms-antagonists F. muscicole and T. viride into the soil makes it possible to activate the work of the antioxidant system of plants and reduce the effects of oxidative stress almost to the level of control. The studied antagonists can be recommended as promising for the development of biological products on their basis in order to protect medicinal plants from fusarium diseases.
