A comparative investigation of monsoon active and break events over the western North Pacific

Abstract This study identifies 86 active events and 66 break events of the western North Pacific summer monsoon (WNPSM) from 1979 to 2020. These active and break events exhibit sharp contrast in large-scale convection and circulation fields. During the active period, deep convection almost covers the entire WNP domain (0°–25°N, 120°–170°E), accompanied by the strengthening of a local monsoon trough and monsoon westerlies extending from the Arabian Sea to the WNP. In contrast, during the break period, along with weakened monsoon westerlies, the subtropical high replaces the monsoon trough to dominate the WNP domain, leading to disappearance of deep convection. Results about the convection evolution at multiple timescales indicate that active/break events are primarily contributed to by the wet/dry phases of intraseasonal oscillations (ISOs). The phase transitions of ISOs are nearly symmetric between active and break events. However, these two types of events present notable asymmetric features in convection anomalies relative to climatology, which can be attributable to the modulation of the seasonal mean component. Specifically, both active and break events correspond to anomalously strong seasonal mean convection, which amplifies (weakens) the convection enhancement (suppression) during the active (break) period and results in normal (enhanced) convection during adjacent periods. The preferred occurrence of active and break events in strong summer monsoons is because related mean backgrounds, including increased low-level positive vorticity, specific humidity, and easterly vertical shear, facilitate the intensification of ISOs. These mean backgrounds are likely induced by SST cooling in the north Indian Ocean and warming in the equatorial central Pacific during the simultaneous summer.

DNA fragmentation factor 40-based therapeutic approaches for cancer: a review article.

DNA Fragmentation Factor (DFF) is a heterodimer protein involved in DNA fragmentation during apoptosis, which acts as a trigger downstream of caspase-3 activation. DFF40 catalytically active homo-oligomers break down chromosomal DNA. Previous scientific investigations have revealed a link between DFF40 expression changes and various cancers. DFF40 deletion or down-regulation has been observed in some cancers. Consequently, therapeutic strategies involving the DFF40 molecule compensating led to an increased rate of cancer cell apoptosis. In this review article, we aimed to introduce cancers with low expression of this protein first. The second part of this paper focuses on studies that utilized exogenous DFF40 protein produced by recombinant DNA technology and surveyed during in vitro and in vivo tests. Finally, compensation for diminished expression of the mentioned protein via gene therapy-based techniques to make up for this apoptotic molecule's low expression is the topic of thelast part of this review article.

Mind-Body Classroom Strategies: Techniques to Reduce Elementary Student Stress Following Active Shooter Drills

Active shooter drills are widely used in schools throughout the United States, with more than 92% of public schools having an active shooter plan. These drills can increase student stress and anxiety and can have a variety of negative effects, such as somatic complaints, anxiety, poor self-regulation of emotions and behaviors, risk for depression, and prevalence of obesity and eating disorders. This article describes the efficacy of physical activity breaks, mindful breathing techniques, and emotional regulation strategies to reduce stress reactivity and enhance recovery in elementary-age students following active shooter safety drills. A list of example activities is provided for each of the three stress management categories. Each of the activities can be adapted to various developmental levels (i.e., K-12), settings (i.e., classroom, hallway, outdoors), and time availability (i.e., one minute to 10 minutes). The strategies may also be utilized following other emergency drills or during other times of high student and classroom stress.

Impact of yoga on the cognitive function among desk‐based workers

IntroductionProlonged sitting negatively impacts cognitive functions, such as working memory and inhibitory control. As sedentary behaviour rises in workplaces, interventions like yoga breaks, which combine physical activity and mindfulness, may mitigate these effects. While specific research on yoga breaks is limited, related studies suggest potential cognitive benefits. MethodsThis prospective, single-centre crossover trial took place from September 2022 to January 2023 at the Radiology Lab, KMC Manipal. Participants experienced three sessions: uninterrupted sitting, pranayama breaks, and yoga breaks, each lasting four hours. Executive functions were assessed hourly using computer-based tests (Eriksen’s Flanker Test and N-Back Test). Statistical analyses included repeated measures ANOVA and Friedman’s test. ResultsParticipants, with a mean age of 30.24 years, showed fastest reaction times during the yoga intervention in the Flanker Test, followed by pranayama and sitting. However, accuracy did not significantly differ between groups in both tests.Reaction times decreased significantly from the 0th to the 2nd and 4th hours in the Flanker Test, but not between the 2nd and 4th hours. In the N-Back test, accuracy declined over time for all interventions, without significant group differences. ConclusionYoga and pranayama breaks potentially improve reaction times during prolonged sitting but do not significantly impact accuracy in cognitive tasks. These findings suggest that while activity breaks can enhance certain cognitive functions, further research is needed to optimize interventions for cognitive health in sedentary work environments.

A New Paradigm for Active–Break Cycle in the Indian Summer Monsoon

Abstract A multichannel singular spectrum analysis of 121 years of daily rainfall over India and 43 years of outgoing longwave radiation and horizontal wind has revealed two dominant intraseasonal oscillations (ISOs) that describe the space–time variability of monsoon rainfall. The two nonlinear oscillations are not perfectly periodic but exhibit broadband spectra centered at 45 and 28 days. These modes have coherent and near-regular spatial structure and temporal variations. This study posits that the two nonlinear oscillations provide a consistent and comprehensive framework to study the variability and predictability of intraseasonal rainfall variations. The active and break cycles of monsoon rainfall over India have been traditionally defined by using an arbitrarily chosen duration of persistence of arbitrarily chosen amount of rainfall averaged over an arbitrarily chosen area. This study shows that the phases of the two objectively derived modes of variability provide an objective method for defining the active and break cycles. The two ISOs are further shown to make negligible contribution to the seasonal mean rainfall and its interannual variability. This study proposes that the investigations of the origins of these nonlinear modes, and modulations of their amplitudes and phases, provide a new paradigm for future research on validation and predictability of intraseasonal variations in climate models.

Short, frequent physical activity breaks improve working memory while preserving cerebral blood flow in adolescents during prolonged sitting - AbbaH teen, a randomized crossover trial

PurposePhysical activity (PA) breaks during school lessons have been suggested as a promising strategy to improve working memory performance in children and adolescents. There is a lack of studies investigating the underlying physiological mechanisms of PA on cognition, especially among adolescents. This study aimed to investigate the effects of different types of short frequent PA on adolescents’ cognitive task-related changes in cerebral blood flow in the prefrontal cortex (PFC) and working memory performance compared to prolonged sitting.MethodsIn this randomized crossover study, adolescents visited the laboratory on three different occasions for 80-minute sessions of prolonged sitting interrupted by four breaks for three minutes of simple resistance training (SRA), step-up at a pre-determined pace (STEP), or remaining seated (SOCIAL). Before and after each session, cognitive task-related changes in cerebral blood flow (oxygenated-hemoglobin, Oxy-Hb) during working memory tasks (1-, 2-, 3-back tests) were measured using functional near-infrared spectroscopy in the PFC. Accuracy and reaction time were derived from the working memory tasks. Linear mixed-effect models were used to analyze the data.ResultsA total of 17 students participated (mean age 13.6 years, 11 girls). Significant time x condition interactions were noted for Oxy-Hb in the most demanding working memory task (3-back), with a decrease following prolonged sitting in the SOCIAL condition compared to both the SRA (β 0.18, 95% CI 0.12, 0.24) and the STEP (β 0.11, 95% CI 0.05, 0.17). This was observed in parallel with improvements in reaction time following SRA (β -30.11, 95% CI -59.08, -1.13) and STEP (β -34.29, 95% CI -69.22, 0.63) although this was only significant for the SRA and no improvements in the SOCIAL condition.ConclusionWe found that short frequent PA breaks during prolonged sitting among adolescents can prevent the decrease in cognitive task-related changes in cerebral blood flow that occur following prolonged sitting. This was observed simultaneously with improvements in working memory, indicating that changes in cerebral blood flow could be one factor explaining the effects on working memory. Future studies should investigate the efficacy of implementing these PA breaks in schools.Trial registrationRetrospectively registered on 21/09/2020, ClinicalTrial (NCT04552626).

Symposium 3: Investigating the background – taking a Merleau-Pontian phenomenological approach to Networked Learning

This paper is a theoretical paper on phenomenological methodology. My point of departure is Merleau-Ponty’s concept of figure-background in perception and his view of the role which the body has in establishing figure-background in each specific situation. I argue that Merleau-Ponty’s approach differs from other phenomenological approaches because of this focus: his highlighting of the background as essential for understanding what appears as figure to consciousness (the object of experience). His focus on the background has methodological implications for how to investigate a phenomenon (perform phenomenological analyses). A key Merleau-Pontian methodological strategy is to focus on breakdown situations, that is, situations where ordinary practical activity breaks down, because the breakdowns can provide indications about that which is taken for granted in the usual well-performed practical activity. I illustrate what Merleau-Pontian phenomenological analysis within Networked Learning could be with two examples. One is from synchronous online learning situations: the figure of eye contact via a webcam. The other one concerns contemporary renderings of the networked learners in the figure of hybrid networked learning situations of students today. For both examples, I tease out what relevant backgrounds are and how a focus on those backgrounds highlights other aspects in networked learning than the ones other phenomenological analyses focus on.

The Erasmus+ EUMOVE project-a school-based promotion of healthy lifestyles to prevent obesity in European children and adolescents.

The aim of this study was to describe the goals, activities, and methods of EUMOVE project in developing a set of resources targeting both primary and secondary schools that allow the entire educational community to promote healthy lifestyles (HL). The EUMOVE project is an Erasmus+ program based in the Creating Active Schools (CAS) framework. The project lasted 3 years and was developed by 14 academic and non-governmental institutions from Spain, Portugal, France, Italy, and the UK. EUMOVE was divided into three phases. In the first phase, several work packages were carried out aimed to ensure the coordination/management of the project activities. In the second phase, seven educational resources strengthened by rigorous scientific research were developed to promote HL from schools. During the last phase, all the resources were disseminated through scientific seminars, workshops with families and teachers, and the online promotion by the non-governmental institutions of each country. The EUMOVE project developed and promoted a smartphone APP, video/activity repository of physically active lessons, active break virtual platform, learning units, and parent/teachers/school-leaders' guidelines to promote physical activity, active commuting, active school playgrounds, healthy diet, and sleep habits. To our knowledge, EUMOVE is the first European project to provide a set of practical tools based on scientific evidence to help schools or future school-wide interventions implement a paradigm shift based on the CAS framework for the promotion of HL. Future research will need to investigate the implementation, effectiveness, and scalability of this proposal.

USING ACTIVE AND PASSIVE BREAKS DURING HANDBALL GAMES ACCORDING TO SPECIALISTS

In most team sports games, only a few of the players enter the starting line of the match, and the others are bound by regulation to sit on the bench and remain inactive. The first objective of our research was to obtain an informed opinion from the coaches in Romania regarding the role of passive and active breaks in the possible evolution of reserve players in the match. In addition, we wanted to know whether specialists use programs to preserve the optimal capacity for effort during sports activities. As a research tool, we used the opinion questionnaire with 24 respondents. We analysed the data for normality and then expressed it by mean, minimum and maximum values. We appreciated the degree of correlation (rho) between the studied parameters by calculating the Spearman correlation coefficient. A value of the coefficient of statistical significance p <0,05 was considered significant. At the same time, we determined the internal consistency of the research tools by using the Alfa Cronbach coefficient for the Likert scale applied to our questionnaire. We have analysed the relationship between the „effects of passive” breaks and „opportunity of using active” breaks to see if coaches' opinion on the effects of passive breaks is correlated with their appreciation of the appropriateness of using active breaks. The conclusion of our study is that we cannot appreciate that the opinion of Romanian coaches on the effects of passive breaks on the players on the sidelines is consistent with the actual use of some pause programs active, focused on maintaining the optimal functioning capacity of the body of the player.

Raindrop size distributions of summer monsoon rainfall observed over Eastern India

The present study aims to quantify the raindrop size distributions (RSDs) of Indian summer monsoon (ISM) rainfall over a tropical eastern Indian station, Rourkela using five years (2018–2021) of Thies disdrometer measurements. The RSD measurements of ISM rainfall at Rourkela are segregated into active and break spells using the standardized rainfall anomalies over the study area. The RSDs characteristics of active and break spells are analyzed and their empirical relations, which are appropriate for precipitation estimation algorithms, are also reported. A significant annual and monthly variations in RSDs is noticed between the active and break spells of the ISM rainfall over the study region. The probability distribution function (PDF) RSDs parameters (rainfall rate, liquid water content, mass-weighted mean diameter, and normalized intercept parameter) demonstrated clear distinctions between active and break spells. The active spells showed higher rainfall amounts, large mass-weighted mean diameter, and smaller normalized intercept parameters over the break spells. A further segregation of active and break spells into stratiform and convective types revealed more large size drops in convective (stratiform) precipitations of active (break) spells. Occurrence of higher rainfall amounts and large size raindrops in the active spells over the break spells can be attributed to the presence of abundant moisture and convective activity in active spells. Furthermore, the radar reflectivity-rainfall rate (Z–R), shape and slope (μ–Λ), and mass-weighted mean diameter-rainfall rate (Dm-R) relations established for the active and break spells could aid in improving the precipitation estimations of over the study region.

Vertical Energy Fluxes Driven by the Interaction between Wave Groups and Langmuir Turbulence

Abstract Data from an air–sea interaction tower are used to close the turbulent kinetic energy (TKE) budget in the wave-affected surface layer of the upper ocean. Under energetic wind forcing with active wave breaking, the dominant balance is between the dissipation rate of TKE and the downward convergence in vertical energy flux. The downward energy flux is driven by pressure work, and the TKE transport is upward, opposite to the downgradient assumption in most turbulence closure models. The sign and the relative magnitude of these energy fluxes are hypothesized to be driven by an interaction between the vertical velocity of Langmuir circulation (LC) and the kinetic energy and pressure of wave groups, which is the result of small-scale wave–current interaction. Consistent with previous modeling studies, the data suggest that the horizontal velocity anomaly associated with LC refracts wave energy away from downwelling regions and into upwelling regions, resulting in negative covariance between the vertical velocity of LC and the pressure anomaly associated with the wave groups. The asymmetry between downward pressure work and upward TKE flux is explained by the Bernoulli response of the sea surface, which results in groups of waves having a larger pressure anomaly than the corresponding kinetic energy anomaly, consistent with group-bound long-wave theory.

Physically Active Lifestyles within the School context: Morpho-Physiological and Functional Aspects

The school context embodies the optimal environment for educating children towards the adoption of active lifestyles. This is auspicious not only in terms of physical health but also from a psycho-pedagogical and social standpoint. The need to integrate physical activity into the school routine, particularly in primary education, where behaviors are established and carried on into later stages of life, emerges clearly from the scientific literature. Health education sessions with a focus on preventive measures can be organized by the school’s medical services for the benefit of students. It is imperative within educational practices to view the motor domain as a crucial instrument for instilling appropriate lifestyles, enhancing cognitive growth, fostering inclusivity, and addressing psycho-emotional and socio-relational aspects. The school environment can significantly contribute by serving as a pivotal setting for promoting physical activity throughout various periods of the day. Movement can be incorporated into teaching activities, and active breaks can be integrated into class hours, either before or after lessons. This study stems from a comprehensive examination of the existing literature regarding the correlation between the school environment, health, and preventive health promotion. It recognizes the ongoing nature of the issue and the need for further investigation to align with forthcoming changes. Keywords: physical activity, physiology, school.

Aerobic and Anaerobic Exercise's Impact on Cognitive Functions in Eighth Grade Students.

The present study examined the impact of aerobic and anaerobic exercise on cognitive abilities in eighth grade students at one middle school in southeastern US. It is known that youth do not meet recommended physical activity levels, yet there is research demonstrating a clear connection between aerobic exercise and academic performance. There is a gap in evidence regarding anaerobic exercise and cognitive capabilities. If professionals know which type of exercise is most beneficial for enhancing cognition in youth, it will behoove them to incorporate these practices in physical education and other areas throughout the school day for students. Thus, this research aimed to answer the following question: what is the effect of both aerobic and anaerobic exercise on the cognitive functions of eighth grade students, specifically measuring working memory, attention, and impulsivity? Fifty research participants (N = 31 males, 18 females, 1 other), aged 13-14, consented/assented to the complete study protocols. Participants engaged in an experiment containing three different cognitive tasks after partaking in three separate exercise conditions. The cognitive measures were the Stroop color-word task, the Flanker test, and the Go/No Go task, which all measured reaction time and the number of correct responses. The exercise conditions were baseline (after no exercise), aerobic (after a continuous running activity in PE), and anaerobic (after completing an interval dumbbell workout in PE). Each condition took place on a separate day to decrease the effect of confounding variables. The data were analyzed using the Scheffe modification of the MANOVA to determine whether multiple levels of the independent variable influenced the dependent variables (the reaction time and number of correct responses) or if a combination of variables influenced the outcomes. Each cognitive test was analyzed separately. The results showed that the exercise condition did significantly impact the reaction time and the number of correct responses for the Stroop color-word task [F(4, 254) = 8.59, p < 0.001; Pillai's Trace = 0.24]. Specifically, aerobic exercise improved both reaction time (p < 0.001) and the number of correct responses (p = 0.001) compared to baseline, while anaerobic exercise improved just reaction time compared to baseline. To find out more detailed information about the specific dependent variable affected by the exercise program, individual ANOVA tests were conducted, resulting in statistical significance for both the number of correct responses and reaction time regarding the program. The partial Eta2 of 0.07 for the number of correct responses and 0.24 for reaction time indicated that 7% of the variance in correct responses and 24% of the variance in reaction time could be explained by the exercise program. While both are significant, reaction time is more impacted by exercise program than correct responses are. Given these findings, it is recommended that aerobic physical activity be offered in school prior to assigning cognitively challenging tasks, while quick anaerobic activity breaks should be used to refocus students' attention. More research should be conducted to examine other cognitive abilities, as well as in other populations.

Take a Break for Memory Sake! Effects of Short Physical Activity Breaks on Inhibitory Control, Episodic Memory, and Event-Related Potentials in Children.

The pervasive sedentary lifestyle exacerbated by the COVID-19 pandemic has significantly reduced physical activity (PA) among school-age children, necessitating innovative strategies to evaluate short PA breaks that are feasible in a classroom setting. This study explored the cognitive and neurophysiological (electroencephalography; EEG) impacts of short bouts of different PA modalities on inhibitory control (flanker task) and episodic memory (word recognition task) in children. Utilizing a within-participants cross-over design, thirty-six children (n = 36; 9-12 years old) attended the lab on three separate days with each visit including either a 9 min bout of sustained moderate-intensity cycling, high-intensity interval exercise (HIIE), or seated rest. Event-related potentials (ERPs) were assessed during the flanker task (P3 component) and the word recognition task (LPC and FN400 components) to elucidate the neural mechanisms underpinning behavioral outcomes. Findings indicated no differences in flanker performance but greater episodic memory recall for HIIE compared to seated rest. Neurophysiological results revealed no differences for P3, but notably larger amplitude for LPC and FN400 postcycling, particularly over parietal electrode sites. These results underscore the potential of short PA breaks to improve cognitive and neurocognitive function in children, offering a feasible integration strategy into daily school routines without extensive time commitment.

Ten-Minute Physical Activity Breaks Improve Attention and Executive Functions in Healthcare Workers.

Occupational health is a major problem in modern work environments. Physical activity breaks (PABs), short exercise periods delivered during working hours, incorporating exergames or outdoor activities, have emerged as a novel approach that could be used to improve work efficiency and workplace wellbeing. Therefore, this study aimed to investigate the impact of PABs on attention levels and executive functions in healthcare workers. A total of 27 healthcare workers (M = 14, W = 13; 49.55 ± 12.46 years), after 4 h of work, randomly performed one of three 10 min conditions weekly in a counterbalanced order: No Physical Activity Break (NPAB); Outdoor Physical Activity Break (OPAB); Physical Activity Break with Exergame (PABEx). After the conditions, executive functions and selective attention were assessed by the Stroop Color and Word Test (SCWT), and the Trail Making A,B test (TMT A,B), respectively. Significant differences between OPAB and NPAB as well as between PABEx and NPAB in the TMT-A test χ2(2) = 44.66 (p < 0.001) and TMT-B test χ2(2) = 48.67 (p < 0.001) were found, respectively. TMT-A and SCWT interference/time scores of the PABEx and OPAB conditions were significantly lower than those of NPAB (p < 0.001). In the SCWT interference/error score, no significant difference was found between the PABEx and NPAB (p > 0.05), but the score was statistically lower in the OPAB condition than PABEx (p = 0.001) and PABEx condition compared to OPAB for TMT-A (p = 0.001). Findings showed that the OPAB and PABEx conditions are effective in improving selective attention and executive functions in healthcare workers. Employers can foster a healthier and more productive workforce by promoting a culture of movement and prioritizing employee health, which in turn can enhance patient care outcomes.

Feasibility and effectiveness of a distance-adapted physical activity intervention in adolescents with obesity during the COVID-19 pandemic.

Pediatric obesity represents one of the most important public health challenges and its prevalence significantly increased during the COVID-19 pandemic. Our prospective study aimed to assess the feasibility of a remote adapted physical activity (PA) intervention and its effectiveness in improving anthropometric indices, metabolic health parameters, as well as cardiopulmonary function and fitness in adolescents with obesity. A PA intervention involving synchronous online lessons combined with asynchronous sessions and promotion of independent PA and "active breaks" to interrupt prolonged sedentary behaviors was proposed to 20 adolescents aged 11-17 years with obesity over a 4-month period. Clinical and anthropometric parameters (weight, height, waist, body composition, blood pressure), metabolic parameters (glycemia, insulinemia, glycated hemoglobin, oral glucose tolerance test [OGTT], lipid profile, presence of hepatic steatosis), cardiopulmonary function and fitness indices (VO<inf>2</inf>max, six-minute walking test [6MWT], upper and lower limb strength test) were evaluated before and after the intervention. Twenty adolescents with obesity were enrolled (11 male [55%], aged 14.1±1.5 years, BMI SDS 3.1±0.5). Eighteen participants (90%) successfully completed the project, and no adverse events were reported. We observed an increase in cardiovascular and muscle fitness [higher VO2peak, maximal workload, better performance at limb strength and 6MWT (all P<0.05)], increased lean body mass (P=0.005), and an improvement of glucose metabolism response with a reduction of insulin concentrations during OGTT (P=0.043). Participation in the training program was feasible and effective in improving cardiovascular fitness, glucose metabolism, body composition, strength, and endurance in adolescents with obesity during the COVID-19 pandemic.

Active Breaks Reduce Back Overload during Prolonged Sitting: Ergonomic Analysis with Infrared Thermography.

Background: Prolonged sitting is a potential risk factor for musculoskeletal disorders in office workers. This study aims to evaluate the effect of active breaks on reducing muscle overload in subjects who sit for long periods using infrared thermography (IRT). Methods: A sample of 57 office workers participated in this study and were divided into two groups: active breaks (ABs) and no active breaks (NABs). The NAB group sat continuously for 90 min without standing up, while the AB group performed stretching and mobility exercises every 30 min. IRT measurements were taken every 30 min before the active breaks. Results: The results highlight that the skin temperature of the back increased significantly in both groups after 30 min of sitting; however, in the subsequent measurements, the AB group showed a decrease in temperature, while the NAB group maintained a high temperature. Exercise and time point of measurement all reported p-values < 0.001; there were no statistically significant differences between the Δt0-1 of the NAB and AB groups, while the Δt1-2 and Δt1-3 of the NAB and AB groups showed statistically significant differences for all back regions. Conclusions: The clinical relevance of this study confirms the negative effects of prolonged sitting on the health of the back, demonstrating that active breaks can reduce back strain, emphasizing the need for workplace interventions. In addition, IRT represents a non-invasive method to assess back muscle overload and monitor the effectiveness of interventions in all categories of workers who maintain a prolonged sitting position. The main limitation of this study is the absence of a questionnaire for the assessment of back pain, which does not allow a direct correlation between temperature changes and back pain outcomes.
