Novel Multi-Segment Foot Model Incorporating Plantar Aponeurosis for Detailed Kinematic and Kinetic Analyses of the Foot With Application to Gait Studies

Kinetic multi-segment foot models have been proposed to evaluate the forces and moments generated in the foot during walking based on inverse dynamics calculations. However, these models did not consider the plantar aponeurosis (PA) despite its potential importance in generation of the ground reaction forces and storage and release of mechanical energy. This study aimed to develop a novel multi-segment foot model incorporating the PA to better elucidate foot kinetics. The foot model comprised three segments: the phalanx, forefoot, and hindfoot. The PA was modeled using five linear springs connecting the origins and the insertions via intermediate points. To demonstrate the efficacy of the foot model, an inverse dynamic analysis of human gait was performed and how the inclusion of the PA model altered the estimated joint moments was examined. Ten healthy men walked along a walkway with two force plates placed in series close together. The attempts in which the participant placed his fore- and hindfoot on the front and rear force plates, respectively, were selected for inverse dynamic analysis. The stiffness and the natural length of each PA spring remain largely uncertain. Therefore, a sensitivity analysis was conducted to evaluate how the estimated joint moments were altered by the changes in the two parameters within a range reported by previous studies. The present model incorporating the PA predicted that 13%–45% of plantarflexion in the metatarsophalangeal (MTP) joint and 8%–29% of plantarflexion in the midtarsal joints were generated by the PA at the time of push-off during walking. The midtarsal joint generated positive work, whereas the MTP joint generated negative work in the late stance phase. The positive and negative work done by the two joints decreased, indicating that the PA contributed towards transfer of the energy absorbed at the MTP joint to generate positive work at the midtarsal joint during walking. Although validation is limited due to the difficulty associated with direct measurement of the PA force in vivo, the proposed novel foot model may serve as a useful tool to clarify the function and mechanical effects of the PA and the foot during dynamic movements.
Knowledge Management and Technology Management: The Use of YouTube among Preschool Teachers

Knowledge management is the term used to describe approaches that knowledge workers employ in fulfilling their assigned tasks. The use of technology eases the process of completing their work because it provides systematic methods of managing the process of applying knowledge. Therefore, the current study seeks to find answers on the use of YouTube regarding the type of content selected by the teachers when using the platform and the kind of activities that require them to use the channel for teaching and learning purposes. The study uses qualitative data inquiries to collect responses from 23 preschool teachers. Four themes are formulated as findings in the current study. They are “YouTube consolidates teaching and learning,” “use of YouTube for educational songs,” “use of YouTube to improvise teacher-made songs,” and “nonusage of YouTube. ” It concludes that knowledge is transferred explicitly when preschool teachers use the platform as a resource for teaching and learning. The technology, that is, YouTube, has somewhat assisted them in teaching the preschoolers in their early literacy development by watching entertaining yet educational materials. The study implied that YouTube could be an educational resource that teachers can use in teaching young learners. Also, it suggested that it could be a source of information that teachers may use to find relevant materials for their classes.
Exploring the Factors That Influence the Intention to Co-create Open Educational Resources: A Social Exchange Theory Perspective

Purpose Based on social exchange theory, this study aimed to investigate, from the cost-benefits perspective, the intention to co-create open educational resources (OER). Design/Methodology/Approach Participants in the study included 311 undergraduate students selected from those enrolled in a course on the China University MOOC platform. Regression analysis was conducted to examine cost and benefits factors that influenced participants’ intentions to co-create OER. Findings (1) From the perspective of benefits, expected reciprocity, increase in knowledge self-efficacy, and creative self-efficacy were found to significantly and positively impact the intention to co-create OER, while increase in internet self-efficacy was not. (2) From the perspective of cost, perceived effort and perceived privacy were found to significantly and negatively impact the intention to co-create OER, while perceived intellectual property risks were not significant. Originality/Value Three strategies are recommended to promote the intention to co-create OER based on the findings of this study: (1) focusing on OER communities and developing reciprocity norms; (2) popularizing and promoting knowledge and use of Creative Commons copyright licenses; (3) providing easy-to-use online resource editing tools for use with OER repositories. Research Limitations/Implications Future research should explore other ages, cultural backgrounds, and types of online learning experience to help broaden the universality of the results.
Walking the Tightrope: Coopetition Capability Construct and Its Role in Value Creation

Prior research emphasizes the paradoxical nature of coopetition and the need for specialized capabilities—coopetition capability—to deal effectively with opportunities and challenges stemming from the simultaneous pursuit of cooperation and competition and to create superior value. However, we know little about the underlying conceptual properties of coopetition capability (construct clarity) and lack a reliable and valid scale to measure it (construct validity). We conduct a study in three phases to address this critical gap. First, building on paradox literature, we conceptualize coopetition capability as a multidimensional construct reflected by three underlying dimensions: coopetition mindset, analytical acumen, and executional skills. Second, we develop a 15-item psychometrically valid scale using a sample of 647 coopetitive alliances in high-technology sectors. Finally, using a matched sample of 536 coopetitive alliances, we extend the focal construct's nomological network by examining two relationships: coopetition experience's impact on coopetition capability and the effect of coopetition capability on the relationship between the coopetition paradox and value creation. Overall, our paper lays a foundation for deeper theory development and empirical research on coopetition by providing much-needed construct clarity and psychometrically valid measures for coopetition capability.
Local adaptation through countergradient selection in northern populations of Skeletonema marinoi

Marine microorganisms have the potential to disperse widely with few obvious barriers to gene flow. However, among microalgae, several studies have demonstrated that species can be highly genetically structured with limited gene flow among populations, despite hydrographic connectivity. Ecological differentiation and local adaptation have been suggested as drivers of such population structure. Here we tested whether multiple strains from two genetically distinct Baltic Sea populations of the diatom Skeletonema marinoi showed evidence of local adaptation to their local environments: the estuarine Bothnian Sea and the marine Kattegat Sea. We performed reciprocal transplants of multiple strains between culture media based on water from the respective environments, and we also allowed competition between strains of estuarine and marine origin in both salinities. When grown alone, both marine and estuarine strains performed best in the high‐salinity environment, and estuarine strains always grew faster than marine strains. This result suggests local adaptation through countergradient selection, that is, genetic effects counteract environmental effects. However, the higher growth rate of the estuarine strains appears to have a cost in the marine environment and when strains were allowed to compete, marine strains performed better than estuarine strains in the marine environment. Thus, other traits are likely to also affect fitness. We provide evidence that tolerance to pH could be involved and that estuarine strains that are adapted to a more fluctuating pH continue growing at higher pH than marine strains.
Cancer-Testis Antigen LDH-C4 in Tissue, Serum, and Serum-Derived Exosomes Serves as a Promising Biomarker in Lung Adenocarcinoma

Objective As a cancer-testis antigen (CTA), human lactate dehydrogenase C4 (LDH-C4) enzyme protein encoded by the LDHC gene has been reported to be involved in the occurrence and development of various malignancies, while its expression and clinical significance in lung adenocarcinoma (LUAD) remain unclear. This study aims to investigate the expression of LDH-C4 in LUAD and its diagnostic and prognostic value. Methods The mRNA and protein levels of LDH-C4 in LUAD and adjacent normal tissues were analyzed based on the UALCAN database, and the prognostic significance was assessed using the LOGpc database. The LDHC mRNA level in serum and serum secretion of LUAD patients was determined by quantitative real-time PCR (qRT-PCR). Based on the high-throughput LUAD tissue chip combined with immunohistochemistry (IHC), the protein level of LDH-C4 in LUAD tissues was measured, and its correlation with clinicopathological features and prognosis was analyzed. Results LDHC expression was upregulated in LUAD, which was related to the clinical stage and poor prognosis of patients. The positive rates of LDHC mRNA expression in serum and exosome of LUAD patients were 78.3% and 66.7%, respectively. The area under the curve (AUC) of serum and exosomal LDHC in the diagnosis of LUAD was 0.8121 and 0.8925, respectively. The expression of LDHC in serum and serum-derived exosomes from LUAD patients was negatively correlated with medical treatment and positively correlated with the recurrence of LUAD. The positive expression rate of LDH-C4 in LUAD tissues was 96.7% (89/92), which was significantly higher than that in adjacent normal tissues 22.6% (19/84) (p < 0.001). The median overall survival (OS) time of patients with a high expression of LDH-C4 was significantly shorter than that of patients with low expression (34 months versus 62 months) (p = 0.016). Further relative risk analysis exhibited that the expression of LDH-C4 was an independent prognostic factor of OS in patients with LUAD. Conclusions LDHC/LDH-C4 expression was upregulated in LUAD, and LDH-C4 could be used as a molecular indicator of the prognosis of LUAD. Serum and serum-derived exosomes of LDHC can be used as an important biomarker for the diagnosis, efficacy evaluation, and recurrence monitoring of LUAD.
An Analytical Approach for Frequency Estimation of Modern Power Grid

This letter proposes an analytical method to estimate the frequency of buses of transmission grid based on updated generator speed, internal generator voltages, admittance matrix and bus voltages. The proposed method estimates the buses frequency which are much more reliable, accurate and efficient for transient stability studies in contrast to other existing methods. To demonstrate the efficiency of the proposed approach, the method is applied on IEEE 39 bus test system for frequency support and is compared to other existing methods.
Resilience patterns of Swiss adolescents before and during the COVID-19 pandemic: a latent transition analysis

ABSTRACT This study investigated resilience patterns and predictors of these patterns (i.e. gender and migration background) among Swiss early adolescents in times of COVID-19. A total of 317 pupils participated at two time points. We conducted two separate latent class analyses and a latent transition analysis using mental health issues and protective factors as indicators. The results revealed three groups: resilient (high mental health issues, high protective factors), nonresilient (high mental health issues, low protective factors), and untroubled (low mental health issues, high protective factors). The resilient group was the most stable (91% stability), whereas the untroubled was the least stable (69% stability). Boys were more likely to be part of the untroubled group than the other groups at the second time point. Gender at the first time point and migration background at both time points were nonsignificant as predictors. Findings highlight the importance of group-specific research, health promotion, and interventions.
The impact of natural factors and the interaction of anthropogenic resources on the productivity and energy potential of grasslands

The role of natural factors and the interaction of anthropogenic resources with them was researched. The meadow agroecosystems based on income balance, accumulation, and expenditure of energy yield were assessed. The study has been carried out during 2011-2015 at the long-term (47 years) field experiment of the Institute of Agriculture of the Carpathian region, which includes permanent and temporary grasslands. The dry matter (DM) yield and energy yield (EY) of permanent grassland, mainly depend on mineral fertilization. Application of NPK which includes 60 kg P per ha, 90 kg K per ha, and 90 kg N per ha promotes the acquisition of 8.22 t/ha DM with 155.4 GJ/ha EY. The sum of energy yield from the aboveground mass (71.5 GJ/ha), the root (65.9 GJ/ha) and the soil energy (112.7 GJ/ha) is 250.1 GJ/ha. Production of gross energy is 260.1 GJ/ha from this grassland. The use of phosphorus and potassium fertilizers, lime and growth enhancer has a positive impact on the DM yield, soil fertility, and EY of temporary legume-grass grasslands. This combined fertilizer yields 6.65 t/ha DM and 260.3 GJ/ha of EY. Grasslands for the accumulation of total EY used 91-96% of energy from renewable, that is, natural factors provide a positive balance of energy in the Earth biosphere processes.
RVMOS: Range-View Moving Object Segmentation leveraged by Semantic and Motion Features

Detecting traffic participants is an essential and age-old problem in autonomous driving. Recently, the recognition of moving objects has emerged as a major issue in this field for safe driving. In this paper, we present RVMOS, a LiDAR Range-View-based Moving Object Segmentation framework that segments moving objects given a sequence of range-view images. In contrast to the conventional method, our network incorporates both motion and semantic features, each of which encodes the motion of objects and the surrounding circumstance of the objects. In addition, we design a new feature extraction module suitably designed for range-view images. Lastly, we introduce simple yet effective data augmentation methods: time interval modulation and zero residual image synthesis. With these contributions, we achieve a 19% higher performance (mIoU) with 10% faster computational time (34 FPS on RTX 3090) than the state-of-the-art method with the SemanticKitti benchmark. Extensive experiments demonstrate the effectiveness of our network design and data augmentation scheme.
A Biomechanical Analysis of Shoulder Muscle Excursions During Abduction, After the Treatment of Massive Irreparable Rotator Cuff Tears Using Superior Capsular Reconstruction (SCR), Bursal Acromial Reconstruction (BAR), and SCR with BAR

Introduction Current understanding of the biomechanical effects of treatment options for irreparable rotator cuff (RC) tears is lacking. This study examines how shoulder muscle lengths and excursions are affected by superior capsular reconstruction (SCR), bursal acromial reconstruction (BAR), and SCR with BAR, following a complete supraspinatus tear. Method Six fresh-frozen cadaveric shoulders were examined. Deltoid and RC muscle lengths were measured at 0, 30, 45, 60, and 90° of shoulder abduction under six conditions: (1) intact, (2) partially torn supraspinatus, (3) completely torn supraspinatus, (4) SCR, (5) SCR with BAR, and (6) BAR. Muscle excursions from 0–90° of abduction were then calculated. Results Subscapularis muscle lengths after SCR, BAR, and SCR with BAR were significantly greater (post-hoc Tukey HSD test; p < .01) compared to the other conditions. Supraspinatus, infraspinatus, teres minor, and deltoid lengths were not significantly different (ANOVA test; p > .01) between the conditions. All muscle excursions remained statistically similar between the conditions (ANOVA test; p > .01). Conclusion These findings demonstrate that the use of SCR, BAR, or SCR with BAR for a complete supraspinatus tear, may increase subscapularis muscle length while maintaining other shoulder muscle lengths. An increase in subscapularis length can allow for more effective subscapularis muscle strengthening and increased compensatory function in the long term. Additionally, all shoulder muscle excursions are preserved after partial or complete supraspinatus tears and after SCR, BAR, or SCR with BAR. Therefore, these surgical treatments can initially normalize shoulder muscle function during 0–90° of abduction, after an irreparable supraspinatus tear.
The evolution of the H2O maser emission in the accretion burst source G358.93−0.03

Context. The massive young stellar object (MYSO) G358.93 − 0.03-MM1 showed an extraordinary near-infrared- to (sub-)millimetre-dark and far-infrared-loud accretion burst, which is closely associated with ﬂares of several class II methanol maser transitions, and, later, a 22GHz water maser ﬂare. Aims. Water maser ﬂares provide an invaluable insight into ejection events associated with accretion bursts. Although the short timescale of the 22GHz water maser ﬂare made it impossible to carry out a very long baseline interferometry observation, we could track it with the Karl G. Jansky Very Large Array (VLA). Methods. The evolution of the spatial structure of the 22GHz water masers and their association with the continuum sources in the region is studied with the VLA during two epochs, pre- and post-H 2 O maser ﬂare. Results. A drastic change in the distribution of the water masers is revealed: in contrast to the four maser groups detected during epoch I, only two newly formed clusters are detected during epoch II. The 22GHz water masers associated with the bursting source MM1 changed in morphology and emission velocity extent. Conclusions. Clear evidence of the inﬂuence of the accretion burst on the ejection from G358.93 − 0.03-MM1 is presented. The accretion event has also potentially a ﬀ ected a region with a radius of ∼ 2 (cid:48)(cid:48) ( ∼ 13500AU at 6.75kpc), suppressing water masers associated with other point sources in this region.
Ants (Hymenoptera: Formicidae) increase predation of Belenois solilucis (Lepidoptera: Pieridae) eggs in organic agriculture production systems: a multiple-site field study at Rashad, Sudan

Organic farming is becoming more popular as there is a greater demand for pesticide-free food. Pest control in organic agricultural production requires a set of skills, including the identification of effective predators and land-use practices. Predation by selected Coleopteran, Dipteran, and Hemipteran insects and Araneae is well established, whereas the predatory role of ants (Hymenoptera: Formicidae) has received little attention in the Rashad district, Sudan. This study was carried out to assess the predation rates of Belenois solilucis eggs and the impact of the land use type around the properties on these rates. An experimente involving predation tests on Belenois solilucis eggs and fauna sampling were conducted in 18 areas of organic agriculture in the Rashad district. The study showed that ants can reduce the eggs population by 26.8% per day. At the same time, other predator taxa, primarily Coleoptera, from Coccinellidae and Staphylinidae families, removed only 13% of the eggs. Ant species with the most significant recruiting power were Axinidris acholli, Tapinoma carininotum, and Technomyrmex moerens. Ant genera such as Linepithema, Dorymyrmex, and Camponotus ants were also frequently observed. The proportion of the planted area within a 500-meter radius, in addition to the interaction of other landscape categories, had a minor influence on predation, but only when the predators were not ants. The landscape does not affect predation by predators in general, including ants, or on ant predation in particular.
Leadership in restaurants and its organizational outcomes: a systematic review

The service offered by restaurants is considered part of the population's lifestyle and contributes to the employability and economic growth of the countries. Leadership is an influencing variable for both positive and negative organizational outcomes. The objective of this Systematic Review was to identify the main organizational variables that leadership influences in restaurants. The authors developed specific search strategies for the PsycInfo, Pubmed, Web of Science, Scopus, Embase, Lilacs, Spell, Google Scholar, ProQuest Global, and BDLTD databases. The authors assessed the methodological quality of the included studies using MASTARI. Eighty-one studies were analyzed, 75 studies used quantitative data, and six studies used qualitative between 1996 and 2020. The leadership styles that showed the most favorable results were Transformational Leadership (20.9%), Leader-Member Exchange (14.8%), Supervisor Support (13.6%), and Servant Leadership (11.1%). The most researched organizational outcomes associated with leadership were Intention to Turnover and Turnover (31.9%), Organizational Commitment (22.2%), Work Performance ( 17.2%), and Job Satisfaction (15.8%). The most investigated variables in the surveys on leadership in restaurants were primarily focused on the led, indicating that researchers in the field still see the leader-led relationship in restaurants as the most needed work topic rather than organizational level variables.
Seeking the Light in Intensive Care Unit Sedation: The Optimal Sedation Strategy for Critically Ill Patients

The clinical approach to sedation in critically ill patients has changed dramatically over the last two decades, moving to a regimen of light or non-sedation associated with adequate analgesia to guarantee the patient’s comfort, active interaction with the environment and family, and early mobilization and assessment of delirium. Although deep sedation (DS) may still be necessary for certain clinical scenarios, it should be limited to strict indications, such as mechanically ventilated patients with Acute Respiratory Distress Syndrome (ARDS), status epilepticus, intracranial hypertension, or those requiring target temperature management. DS, if not indicated, is associated with prolonged duration of mechanical ventilation and ICU stay, and increased mortality. Therefore, continuous monitoring of the level of sedation, especially when associated with the raw EEG data, is important to avoid unnecessary oversedation and to convert a DS strategy to light sedation as soon as possible. The approach to the management of critically ill patients is multidimensional, so targeted sedation should be considered in the context of the ABCDEF bundle, a holistic patient approach. Sedation may interfere with early mobilization and family engagement and may have an impact on delirium assessment and risk. If adequately applied, the ABCDEF bundle allows for a patient-centered, multidimensional, and multi-professional ICU care model to be achieved, with a positive impact on appropriate sedation and patient comfort, along with other important determinants of long-term patient outcomes.
