AbstractEffects of salinity caused by 150 mM NaCl on primary photochemical reactions and some physiological and biochemical parameters (K+/Na+ ratio, soluble sugars, proline, MDA) have been studied in five Triticum aestivum L. genotypes with contrasting salt tolerance. It was found that 150 mM NaCl significantly decreased the photosynthetic efficiency of two sensitive genotypes. The K+/Na+ ratio decreased in all genotypes exposed to salinity stress when compared with the control. Salinity stress also caused lipid peroxidation and accumulation of soluble sugars and proline. The amounts of soluble sugars and proline were higher in tolerant genotypes than sensitive ones, and lipid peroxidation was higher in sensitive genotypes. The noninvasive measurements of photosynthesis-related parameters indicated the genotype-dependent effects of salinity stress on the photosynthetic apparatus. The significant decrease of chlorophyll content (SPAD values) or adverse effects on photosynthetic functions at the PSII level (measured by the chlorophyll fluorescence parameters) were observed in the two sensitive genotypes only. Although the information obtained by different fast noninvasive techniques were consistent, the correlation analyses identified the highest correlation of the noninvasive records with MDA, K+/Na+ ratio, and free proline content. The lower correlation levels were found for chlorophyll content (SPAD) and Fv/Fm values derived from chlorophyll fluorescence. Performance index (PIabs) derived from fast fluorescence kinetics, and F735/F685 ratio correlated well with MDA and Na+ content. The most promising were the results of linear electron flow measured by MultispeQ sensor, in which we found a highly significant correlation with all parameters assessed. Moreover, the noninvasive simultaneous measurements of chlorophyll fluorescence and electrochromic band shift using this sensor indicated the apparent proton leakage at the thylakoid membranes resulting in a high proton conductivity (gH+), present in sensitive genotypes only. The possible consequences for the photosynthetic functions and the photoprotection are discussed.
A closed-form filter for binary time series

Published: June 2021

AbstractNon-Gaussian state-space models arise in several applications, and within this framework the binary time series setting provides a relevant example. However, unlike for Gaussian state-space models — where filtering, predictive and smoothing distributions are available in closed form — binary state-space models require approximations or sequential Monte Carlo strategies for inference and prediction. This is due to the apparent absence of conjugacy between the Gaussian states and the likelihood induced by the observation equation for the binary data. In this article we prove that the filtering, predictive and smoothing distributions in dynamic probit models with Gaussian state variables are, in fact, available and belong to a class of unified skew-normals (sun) whose parameters can be updated recursively in time via analytical expressions. Also the key functionals of these distributions are, in principle, available, but their calculation requires the evaluation of multivariate Gaussian cumulative distribution functions. Leveragingsunproperties, we address this issue via novel Monte Carlo methods based on independent samples from the smoothing distribution, that can easily be adapted to the filtering and predictive case, thus improving state-of-the-art approximate and sequential Monte Carlo inference in small-to-moderate dimensional studies. Novel sequential Monte Carlo procedures that exploit thesunproperties are also developed to deal with online inference in high dimensions. Performance gains over competitors are outlined in a financial application.

AbstractExtractant for estimating plant available arsenic (As) in soil has not been universally established. Moreover, to assess and monitor the complex chemical behaviour of arsenic (As) in soil and subsequently its transfer in crops, a suitable extraction protocol considering the soil properties in relation to crop uptake is required. For this purpose, a pot experiment was conducted to evaluate the suitability of the extractants for determination of extractable As in soil and risk assessment by solubility-free ion activity model (FIAM) with rice (variety: Sushk Samrat) as the test crop. Soil in bulk was collected from six locations of Indo-Gangetic Plain of Bihar, India, varying in physicochemical properties to conduct the pot experiment using five doses of As (0, 10, 20, 40 and 80 mg kg−1). Six extractants namely 0.2 (M) NH4-oxalate, 0.05 (N) HCl + 0.025 (N) H2SO4, 0.5 (M) KH2PO4, 0.5 (N) NH4F, 0.5 (M) NaHCO3 and 0.5 (M) EDTA were used. The results revealed that 0.5 (M) KH2PO4 gave the best correlation with the soil properties and crop uptake and can be considered a suitable extractant of As. Regardless of the As dose and the soil type used, in rice tissue, concentration of As followed the order root > straw > leaf and grain. As high as 94% variation in As content in rice grain could be explained, when 0.5 (M) KH2PO4 extractable As is being used as input for solubility-FIAM. Extractable As cannot be determined by atomic absorption spectrophotometer (AAS) coupled with vapour generation accessory (VGA) when 0.5 (M) EDTA was used as an extractant.

AbstractExcessive digital gaming can have unfavorable effects on gamers’ well-being and everyday functioning. The aims of this study were to investigate the effects of a novel group intervention “Limitless Gaming Bootcamp” on (i) gaming disorder (GD) tendencies, (ii) the amount of time spent on leisure activities, and (iii) subjective well-being among Finnish young adults, and to determine the persistence of the intervention’s influence over time. A one-group pre- and post-test design with no control group was used. Thirty-seven participants were enrolled in the study. The inclusion criteria were being between the ages of 18 and 29; self-reported excessive gaming; a willingness to get support in monitoring one’s gaming behaviour; and a fluency in Finnish. Participants completed a 10-session group intervention designed to enhance conscious gaming behavior and well-being. Baseline, post-test, and six month follow-up measurements were conducted to gather data. Variables measured included background variables, gaming disorder tendencies (Problematic Online Gaming Questionnaire, POGQ), self-reported time spent on various leisure activities, and subjective well-being (Short Form of the Clinical Outcomes in Routine Evaluation Outcome Measure, CORE-SF/A). The time spent on gaming decreased from pre- to post-intervention measurement and further to the six month follow-up, and participants exhibited less severe GD symptoms during the post-intervention phase and six months after the intervention. Gradual improvements in subjective well-being were also observed. The group intervention was found to be particularly effective at reducing the severity of GD symptoms.

Uniqueness of Curvature Measures in Pseudo-Riemannian Geometry
Authors: Bernig Andreas , Faifman Dmitry , Solanes Gil 
Published: June 2021

AbstractThe recently introduced Lipschitz–Killing curvature measures on pseudo-Riemannian manifolds satisfy a Weyl principle, i.e. are invariant under isometric embeddings. We show that they are uniquely characterized by this property. We apply this characterization to prove a Künneth-type formula for Lipschitz–Killing curvature measures, and to classify the invariant generalized valuations and curvature measures on all isotropic pseudo-Riemannian space forms.

Published: June 2021

Abstract
Quantitative and qualitative characteristics of foraminiferal species within the inferred paleotsunami deposits of southwestern Andaman Island were examined using sediment samples from six geoslice sections up to a depth of ~2.5m. In this study, it is considered that the foraminiferal assemblages of the 2004 tsunami deposit (Unit b) as a modern analogue to trace similar events in the geological past. Paleontological and quantitative data analysis suggests 2 biofacies in the stratigraphy. Biofacies I is indicative of a subtidal sediment provenance and its mixing with intertidal sediments due to the tsunami, whereas, Biofacies II is an intertidal/marshy sediment provenance/environment. Foraminiferal tests &gt;180µm in dimension in the tsunami facies (Biofacies I) show abrasion marks, which otherwise show high preservation potential than the pre-tsunami (Biofacies II) that indicates high dissolution activity and low preservation potential. Based on these inferences, 4 tsunami zones, 4 marsh zones, and 1 basin filling zone was elucidated in the stratigraphical column. In order to refine the chronostratigraphy of this area, the contemporaneous foraminifera recovered from a 15cm thick paleotsunami deposit (Unit g) were dated using 14C accelerator mass spectrometry (AMS). The AMS age suggests that AD 1005-1190 was the predecessor of 2004 Sumatra-Andaman earthquake (Mw 9.3) and associated Indian Ocean tsunami.
Geology, Structure and Geochemical Features of the Latérites with Anomalous Ti-V-Cr and REE of the Dhandraul Formation of the Vindhyan Supergroup, Eastern India
Authors: Yadav Pawan Kumar , Das Manorama 
Published: June 2021

Abstract
The present paper reports an important amount of Ti-V-Ga and REE enrichments in the hitherto-unreported eighteen bodies of ferruginous and aluminous laterite capping over the Dhandraul Formation of the Vindhyan Supergroup, Eastern India. It is brown to deep reddish-brown, limonitic, massive, and having a pisolitic form which is mainly rounded to subrounded and filled up of clay, bauxite, limonite, hematite, goethite, and surface encrustation of ferruginous material. Laterites are chiefly composed of ferruginous minerals like hematite, magnetite along with secondary jaspery material and limonite, goethite, in association with silicates and clay minerals. The analyzed samples show high values of Ti, V, Ga, and LREE like La, Ce, Pr, Nd, and Eu along with some significant values of Sm, Gd, Dy, and Yb. TiO2 value is ranging from 0.72 to 18.84 % with an average of 9.77 wt. % which is twenty-two times higher than the crustal abundance. Values of vanadium vary from 48 to 1163 ppm with an average of 593 ppm, and gallium varies from 9 to 90 ppm with an average of 47 ppm, and these values are three to five times higher than the crustal abundance. The ”REE is varying from 208.81 to 899.31 ppm with an average of 484.49 ppm which is three times higher than the crustal abundance. The other significant trace elements identified are in ppm: Co (5 - 135), Cr (76 - 970), Cu (5 - 17), Ni (7 - 48), Pb (6 - 143), and Zn (14 - 231 ppm). This finding has got an enormous impact on the future Ti-V-Ga and REE exploration in the Vindhyan Supergroup in the state of Bihar.

Published: June 2021

Abstract
Petrography and rock magnetic properties of the Dalma volcanics (DV) and associated meta-sediments of Singhbhum mobile belt (SMB) are presented to describe magnetic grain size and Fe-Ti oxide mineralogy of the volcano-sedimentary sequence. Petrography revealed the presence of Ti-magnetite, hematite, ilmenite and pyrite in quartz-biotite-sericite-muscovite schists, quartzites, and volcanic rocks. The average value of magnetic susceptibility (χ) is 5.6 × 10−7 m3/kg, anhysteretic remanent magnetization (ARM) is 2.25 × 10−5 Am2/kg, saturating isothermal remanent magnetization (SIRM) is 403.33 × 10−5 Am2/kg, soft IRM is 240.2 × 10−5 Am2/kg, hard IRM is 77.56 × 10−5 Am2/kg, and natural remanent magnetization (NRM) is 54.1 mA/m. The central tendency of the inter-parametric ratio ARM/χ is 0.06 kAm−1, SIRM/χ is 111.04 kAm−1 and S-ratio is 0.8. Based on results, magnetic mineralogy indicated that the bulk magnetic carrier is stable single domain (SSD) or pseudo single domain (PSD) grains of Fe-Ti oxides with minor iron sulphides such as pyrite, greigite and pyrrhotite. Petrography and rock magnetic studies suggest that the magnetic carriers are chiefly secondary in origin and the NRM is modified over time.
Gamification-less: may gamification really foster civic participation? A controlled field experiment
Authors: Romano Marco , Díaz Paloma , Aedo Ignacio 
Published: June 2021

AbstractIn the context of smart communities, it is essential an active and continuous collaboration between citizens, organizations and institutions. There are several cases where citizens may be asked to participate such as in public decision-making process by informing, voting or proposing projects or in crisis management by sharing precise and timely information with other citizens and emergency organizations. However, these opportunities do not automatically result in participatory practices sustained over time. Mobile technologies and social networks provide the substratum for supporting formal empowerment, but citizen engagement in participation processes is still an open issue. One of the techniques used to improve engagement is gamification based on the humans’ predisposition to games. So far, we still lack studies that can prove the advantage of gamified systems respect to non-gamified ones in civic participation context. In this work, we present a between-group design experiment performed in the wild using two mobile applications enabling civic participation, one gamified and the other not. Our results highlight that the gamified application generates a better user experience and civic engagement.

AbstractAn individual prediction of DFS and OS may be useful after surgery for gastric cancer to inform patients and to guide the clinical management. Patients who underwent curative-intent resection for gastric cancer between January 2010 and May 2020 at a single Italian institution were identified. Variables associated with OS and DFS were recorded and analysed according to univariable and multivariable Cox models. Nomograms predicting OS and DFS were built according to variables resulting from multivariable Cox models. Discrimination ability was calculated using the Harrell’s Concordance Index. Overall, 168 patients underwent curative-intent resection. Nomograms to predict OS were developed including age, tumor size, tumor location, T stage, N stage, M stage and post-operative complications, while nomogram to predict DFS includes Lauren classification, and lymph node ratio (LNR). On internal validation, both nomograms demonstrated a good discrimination with a Harrell’s C-index of 0.77 for OS and 0.71 for DFS. The proposed nomogram to predict DFS and OS after curative-intent surgery for gastric cancer showed a good discrimination on internal validation, and may be useful to guide clinician decision-making, as well help identify patients with high-risk of recurrence or with a poor estimated survival.
No Time to Lift? Designing Time-Efficient Training Programs for Strength and Hypertrophy: A Narrative Review
Authors: Iversen Vegard M. , Norum Martin , Schoenfeld Brad J. , Fimland Marius S. 
Published: June 2021

Abstract
Lack of time is among the more commonly reported barriers for abstention from exercise programs. The aim of this review was to determine how strength training can be most effectively carried out in a time-efficient manner by critically evaluating research on acute training variables, advanced training techniques, and the need for warm-up and stretching. When programming strength training for optimum time-efficiency we recommend prioritizing bilateral, multi-joint exercises that include full dynamic movements (i.e. both eccentric and concentric muscle actions), and to perform a minimum of one leg pressing exercise (e.g. squats), one upper-body pulling exercise (e.g. pull-up) and one upper-body pushing exercise (e.g. bench press). Exercises can be performed with machines and/or free weights based on training goals, availability, and personal preferences. Weekly training volume is more important than training frequency and we recommend performing a minimum of 4 weekly sets per muscle group using a 6–15 RM loading range (15–40 repetitions can be used if training is performed to volitional failure). Advanced training techniques, such as supersets, drop sets and rest-pause training roughly halves training time compared to traditional training, while maintaining training volume. However, these methods are probably better at inducing hypertrophy than muscular strength, and more research is needed on longitudinal training effects. Finally, we advise restricting the warm-up to exercise-specific warm-ups, and only prioritize stretching if the goal of training is to increase flexibility. This review shows how acute training variables can be manipulated, and how specific training techniques can be used to optimize the training response: time ratio in regard to improvements in strength and hypertrophy.

Published: June 2021

AbstractThis paper examines the mediating effect of the novelty ecosystem in the relationship between personality traits, entrepreneurial networking and entrepreneurial ambidexterity. Three hundred eighty-two SMEs in Kampala, Uganda, were studied to explore the influence of the novelty ecosystem. The results show that novelty ecosystem mediates the relationship between personality traits, entrepreneurial networking and entrepreneurial ambidexterity. This suggests that novelty ecosystem is a conduit through which personality traits and entrepreneurial networking relate to entrepreneurial ambidexterity. Business owners/managers should, therefore, create an enabling environment for employees to interact, learn from others through constructive feedback and tolerate learning through slip-ups and putting in place flexible policies to allow creativity. In effect, business owners/managers should create environments that are conducive to opportunity exploration, tension and exploitation.
Distribution of Fetal Anomalies According to International Statistical Classification of Diseases 10th Revision for Congenital Malformations and Chromosomal Defects: A Descriptive Study

Published: June 2021

AbstractReports on incidence of congenital anomalies may be an underestimation of the problem owing to deficiencies in maintaining birth defect registries, reliable medical records, statistics and uniformity in reporting. International Classification of Diseases and Related Health Problems is a system used to translate diagnosis of disease and other health problems from words into an alphanumeric code to provide a common language to share health information across the globe and forms a foundation for identification of health trends and statistics globally. ICD-10 version for congenital malformations, deformities and chromosomal abnormalities classification has been widely applied in the pediatric age group. This study attempts to extrapolate the utility of this classification in coding fetal anomalies prenatally to provide data on their burden and distribution at a tertiary referral centre. To apply ICD-10 coding system for congenital malformations and chromosomal defects antenatally to study the distribution pattern of fetal anomalies and its correlation with postnatal coding, 150 consenting women with prenatal diagnosis of fetal malformation were recruited over a period of 18 months between March 2017 and October 2018. A provisional ICD-10 code was assigned based on antenatal ultrasound findings which was revised again based on postnatal examination or autopsy. Cases were followed up until termination or postnatal day 28 to study the outcome. Correlation of antenatal coding with postnatal code and pattern of distribution of anomalies was studied. Among the 150 cases recruited, 145 (96.7%) were singleton pregnancies with most cases (130) diagnosed for the first time beyond 20 weeks of gestation. Termination of pregnancy was done in 17 (11.3%) cases and 133 pregnancies were continued and among these, intra-uterine demise occurred in 5 (3.3%) and 128 (85.3%) resulted in live birth. Postnatal surgery was done in 20 cases in the neonatal period. Of the live births, 97 (75.8%) were alive on postnatal day 28, while 23 (18.0%) expired. Multisystem involvement was observed in 41 (27.3%) cases and the others had single organ system anomalies, most commonly involving circulatory (29/19.3%) followed by nervous (27/18%) system. ICD coding was similar antenatally and postnatally in 87(58%) cases. It was almost similar in 38 (25.3%), and, in 25 (16.7%) cases, the code was different. Though commonly applied postnatally, prenatal classification of fetal anomalies can be done using ICD-10 to study the pattern and distribution of malformations. However, due to fallacies in prenatal diagnosis and additional information that can be obtained only postnatally, all the prenatally coded cases have to be reviewed postnatally and revised.
