Exotic hysteresis of ferrimagnetic transition in Laves compound TbCo2

ABSTRACT We observed exotic hysteresis behavior in the ferrimagnetic transition of a Laves compound TbCo2. While positive thermal hysteresis was observed in zero-field calorimetric measurements, inverse thermal hysteresis was observed in thermomagnetic measurements as a rare phenomenon. These observations confirmed a first order of the ferrimagnetic transition and revealed a lowering of this order by an external magnetic field. Elastic measurements and high-resolution synchrotron X-ray diffraction measurements suggested that the rare inverse thermal hysteresis can be related to microscopic lattice strains. Those strains are induced by a spontaneous magnetoelastic coupling and are modified by the external magnetic field. GRAPHICAL ABSTRACT IMPACT STATEMENT This work has reconciled discrepancies about the order of the ferrimagnetic transition of a Laves compound TbCo2 by observations of field-dependent thermal hysteresis, including rare inverse thermal hysteresis.
Determining The Rate Of Ipsilateral And Contralateral ACL Rupture Following ACL Reconstruction Surgery In Males And Females: A Systematic Review

Title: Determining the rate of ipsilateral and contralateral ACL rupture following ACL reconstruction surgery in males and females: A SYSTEMATIC REVIEW Introduction: The ACL is one of the two intraarticular ligaments within the knee joint that provides stabilization and resists against anterior translation of the tibia on the femur and rotation. There are many risk factors that may predispose an athlete to an ACL tear or increase their risks, however excessive motion at any plane may cause an ACL rupture. Over the last decade, several research studies have found that the rate of ACL tears following reconstruction surgery has increased compared to previous decades. Objective: The primary objective of this systematic review was to determine the rate of ipsilateral and contralateral ACL ruptures following ACL reconstruction surgery in both males in females. Background: A literature search was performed using PubMed, Medline, Academic Search Premier, and CINAHL databases. Twelve articles met inclusion criteria and minimum score on the Modified Downs and Black for Study Quality checklist. All articles included in this systematic review include findings on the incidence of rupture rates on both the ipsilateral and contralateral ACL tears including percentages within the last 12 years and included both males and females within their study design. Results: Comparison of twelve studies included 6,901 post-operative ACL reconstruction patients, 57% male and 43% female. Patients were followed for an average of 6.9 years, with a follow-up windows ranging from 1 year to 15 years. The ipsilateral ACL re-rupture rate was 6.07% and contralateral ACL re-rupture rate was 6.89%. Overall
Blazar origin of the UHECRs and perspectives for the detection of astrophysical source neutrinos at EeV energies

We demonstrate that a population of blazars can describe the observed spectrum and composition of Ultra-High-Energy Cosmic Rays (UHECRs), and that the dominant contribution comes from low-luminosity BL Lacs. However, a sub-dominant contribution from high-luminosity blazars can lead to a substantial neutrino flux which will peak at EeV energies. We find that it is plausible that this neutrino flux from the sources outshines the cosmogenic neutrino flux produced during the propagation of UHECRs. This has profound implications for the high-energy (EeV) neutrino detection experiments: their main target may be source neutrinos, for which additional search strategies can be used, such as stacking searches, flare analyses, or multi-messenger follow-ups.

Estuarine Exchange Flow Variability in a Seasonal, Segmented Estuary

Small estuaries in Mediterranean climates display pronounced salinity variability at seasonal and event time scales. Here, we use a hydrodynamic model of the Coos Estuary, Oregon, to examine the seasonal variability of the salinity dynamics and estuarine exchange flow. The exchange flow is primarily driven by tidal processes, varying with the spring–neap cycle rather than discharge or the salinity gradient. The salinity distribution is rarely in equilibrium with discharge conditions because during the wet season the response time scale is longer than discharge events, while during low flow it is longer than the entire dry season. Consequently, the salt field is rarely fully adjusted to the forcing and common power-law relations between the salinity intrusion and discharge do not apply. Further complicating the salinity dynamics is the estuarine geometry that consists of multiple branching channel segments with distinct freshwater sources. These channel segments act as subestuaries that import both higher- and lower-salinity water and export intermediate salinities. Throughout the estuary, tidal dispersion scales with tidal velocity squared, and likely includes jet–sink flow at the mouth, lateral shear dispersion, and tidal trapping in branching channel segments inside the estuary. While the estuarine inflow is strongly correlated with tidal amplitude, the outflow, stratification, and total mixing in the estuary are dependent on the seasonal variation in river discharge, which is similar to estuaries that are dominated by subtidal exchange flow.
The Internationalization of B2B Digital Platform Providers: The Role of Cross-National Distance and Digital Characteristics

Digitalization offers new opportunities and changes how firms can explore and enter new markets. Current literature has deepened our understanding of the internationalization process of digital-based firms, but it provides very little guidance on how the specific characteristics of digital artifacts enable and accelerate internationalization or of the role of cross-national distance and cultural difference. We use a longitudinal single-case approach to explore how a Business-to-Business (B2B) platform provider internationalized its operations from inception. The case study illustrates that the ongoing development of the digital service and the integration with new devices played an important role in the firm’s internationalization and expansion into new markets. We also observed that cross-cultural distance and cultural differences played an unexpected role. Finally, we propose avenues for future research.
Examining Associations between the Home Literacy Environment, Executive Function, and School Readiness

ABSTRACT Research Findings: The purpose of the current study was to investigate direct associations between the home literacy environment (HLE) and preschool children’s executive function (EF), academic readiness, and social-emotional competence and to explore the indirect association between the HLE and academic and social-emotional outcomes working through children’s EF. The participants were 102 preschool children from the Midwestern region of the United States. Path analysis showed that the HLE was not directly and significantly associated with social-emotional competence and academic readiness. However, the HLE was significantly related to EF. Further, EF was significantly associated with social-emotional competence and academic readiness. Additionally, a marginally significant indirect effect between the HLE and early language and social-emotional skills, and significant indirect effects between the HLE and early mathematics skills and general academic readiness through EF emerged and warrants further investigation. These findings provide new evidence for a significant association between the HLE and EF and contribute to a robust literature highlighting the importance of EF for academic readiness. Practice and Policy: Findings also inform policy and practice by highlighting that frequent and high-quality parent-child interactions structured around literacy activities promote children’s EF, which in turn, may support strong school readiness skills.
The hallmark and crosstalk of immune cells after intracerebral hemorrhage: Immunotherapy perspectives

Intracerebral hemorrhage (ICH) is one of the most dangerous types of strokes with a high morbidity and mortality rate. Currently, the treatment of ICH is not well developed, mainly because its mechanisms are still unclear. Inflammation is one of the main types of secondary injury after ICH and catalyzes the adverse consequences of ICH. A large number of immune cells are involved in neuroinflammation, such as microglia, astrocytes, oligodendrocytes, lymphocytes, macrophages, and neutrophils. Nevertheless, the characteristics and crosstalk of immune cells have not been fully elucidated. In this review, we endeavor to delve into the respective characteristics of immune cells and their interactions in neuroimmune inflammation, and further elucidate favorable immunotherapeutic approaches regarding ICH, and finally present an outlook.
The effects of perceived conference quality on attendees’ behavioural intentions

ABSTRACT We examined the relationships between dimensions of perceived quality, attendees’ needs and behavioural intentions in conferences. Our findings are based on SEM-PLS of a convenience sample of 295 international attendees participated in 14 academic conferences in Malaysia. We find that only accessibility and self-congruity are positively associated with behavioural intentions. Perceived conference quality is associated with the attendees’ needs and in turn, influences the strength of behavioural intentions. We conclude by discussing the theoretical and practical implications of our model. This study may also give benefits to conference planners with information that allows them to attract and retaining repeat attendees.
lncRNA-ATB promotes stemness maintenance in colorectal cancer by regulating transcriptional activity of the β-catenin pathway

Long non-coding RNA activated by transforming growth factor-β (ATB) was recently reported to be involved in a wide range of physiological and pathological processes. However, the role of ATB in colorectal cancer (CRC) stemness remains unclear. In the present study, the functional role of ATB in maintaining stemness of CRC was determined using colony formation and sphere formation assays, and xenograft models. Reverse transcription-quantitative PCR, western blotting and immunohistochemistry were performed to investigate the mechanisms underlying the effects of ATB. Knockdown of ATB impaired colony formation and sphere formation in CRC cells, accompanied by an inhibition of colon tumor growth. Further results suggested that ATB regulated the transcriptional activity of the β-catenin pathway by inhibiting β-catenin expression. In addition, the results confirmed the role of β-catenin in ATB-mediated regulation of stemness in CRC. Collectively, the results indicated that ATB is a promising therapeutic target for CRC.
Central and Peripheral Weight Gain Affect Trunk Kinematics and Lower-Extremity Muscle Activation Differently During Sit-To-Stand

OF THESIS CENTRAL AND PERIPHERAL WEIGHT GAIN AFFECT TRUNK KINEMATICS AND LOWER-EXTREMITY MUSCLE ACTIVATION DIFFERENTLY DURING SIT-TO-STAND Background: Obesity-induced alterations in biomechanics and muscle recruitment during activities of daily living, such as sit-to-stand (STS) are often attributed to increases in adipose tissue (AT) mass. Central or peripheral distribution of AT may differently affect biomechanics and muscle recruitment. Methods: Fifteen healthy, normal weight (BMI 22.4 ± 1.9 kg/m2, 24.1 ± 4.2 years) subjects volunteered. External loads equivalent to a 5 kg/m2 BMI increase were applied in three conditions: unloaded (UN), centrally loaded (CL), and peripherally loaded (PL). Subjects completed three successful STS movements in a backless chair under each load condition in random order. Motion analysis and lower extremity surface electromyography (EMG) were measured. Results: Compared to UN and CL, PL significantly increased support width during STS. PL also significantly increased maximum trunk flexion compared to CL. Peak and total VM EMG activity were significantly increased during CL, compared to UN and PL. During CL, peak VL EMG activity was significantly greater than UN. Conclusions: Central and peripheral weight gain induce different biomechanical adaptations during STS. Central weight gain increases knee extensor muscle activity during STS independent of biomechanical changes. In contrast, peripheral weight gain increases support width and trunk flexion with minimal EMG changes during STS.
The impact of inverter based systems on power grid stability

Driven by urgent concerns about the impact of greenhouse gas emissions and associated global warming, electric power systems around the world are currently undergoing a rapid transformation away from traditional carbon based energy sources and toward less polluting energy sources including renewables such as wind and solar. This transition is more challenging than is often realized and a number of complex issues must be overcome in diverse areas such as politics, economics, social equity, and technology. Among the great many technical challenges is the question of maintaining supply reliability and grid stability as increasing amounts of renewable energy sources are injected into the existing synchronous generator based grid via grid-tied power electronic inverter systems. This thesis explores this important grid transition stability question when solar energy is injected into the existing grid via photovoltaic cells and grid-tied inverters with certain control strategies. It is shown that serious grid instability leading to grid failure will occur under certain levels of inverter injected power, It is also shown that the level of grid-tied inverter injected power can be increased for certain inverter control loop designs such as virtual synchronous machine loops and also when additional technology such as synchronous condensers are employed.
Associations between endogenous sex hormone levels and adipokine levels in the Multi-Ethnic Study of Atherosclerosis

Background Differences in sex hormone levels contribute to differences in cardiovascular disease (CVD) risk. Adipokines play a role in cardiometabolic pathways and have differing associations with CVD. Adipokine levels differ by sex; however, the association between sex hormone profiles and adipokines is not well established. We hypothesized that a more androgenic sex hormone profile would be associated with higher leptin and resistin and lower adiponectin levels among postmenopausal women, with the opposite associations in men. Methods We performed an analysis of 1,811 adults in the Multi-Ethnic Study of Atherosclerosis who had both sex hormones and adipokines measured an average of 2.6 years apart. Sex hormones [Testosterone (T), estradiol (E2), sex hormone binding globulin (SHBG), and dehydroepiandrosterone (DHEA)] were measured at exam 1; free T was estimated. Serum adipokines (leptin, resistin, adiponectin) were measured at exams 2 or 3. We used multivariable linear regression to examine the cross-sectional associations between sex hormones and adipokines. Results The mean (SD) age was 63 (10) years, 48% were women; 59% non-White participants. For leptin, after adjusting for demographics only, higher free T and lower SHBG, were associated with higher leptin in women; this association was attenuated after further covariate adjustment. However in men, higher free T and lower SHBG were associated with greater leptin levels in fully adjusted models. For adiponectin, lower free T and higher SHBG were associated with greater adiponectin in both women and men after adjustment for CVD risk factors. For resistin, no significant association was found women, but an inverse association with total T and bioT was seen in men. Conclusion Overall, these results further suggest a more androgenic sex profile (higher free T and lower SHBG) is associated with a less favorable adipokine pattern. These findings may provide mechanistic insight into the interplay between sex hormones, adipokines, and CVD risk.
The key to temperate savanna restoration is to increase plant species richness reasonably

Changes in species composition and diversity-productivity relationships during vegetation succession are of great significance for the restoration of degraded grasslands. However, the human intervention of grassland restoration mostly considers the single ecological (diversity) or production (biomass) function of grasslands, and does not fully consider the relationships between the two to improve the restoration effects. In this study, three vegetation types (desert grassland, sandy grassland and temperate savanna) were considered to simulate the three stages of restoration of degraded temperate savanna (early, middle and late restoration). Changes in species composition, diversity, and diversity-productivity relationships during the temperate savanna restoration were explored through spatiotemporal substitution. The results showed that with the progress of succession, xerophytes decreased significantly, mesophytes and hygrophytes increased, C4 plants decreased gradually, and C3 plants increased. The change of species richness was the main reason for community differences in the process of community succession, and species replacement mainly occurred between communities in the early and middle stages of succession. Species richness increased significantly from early to late stage of restoration. Latitude was significantly negatively correlated with species diversity. In the process of vegetation restoration, the impact of species richness, Pielou’s evenness, and β-diversity on biomass gradually developed positively and continued to increase, while the Simpson index showed the opposite effect. This study provides references for the restoration of temperate savanna and emphasizes the ecological and productive functions of the grassland should be taken into account in the restoration strategy.

The effect of methyl and methoxy substituents on dianilines for a thermosetting polyimide system

4,4′-Methylenedianiline (MDA) is widely used in high-temperature polyimide resins, including polymerization of monomer reactants-15. The toxicity of MDA significantly limits the manufacturability using this resin. Modifying the substitution and electronics of MDA could allow for the reduction of toxicity while maintaining the high-performing properties of the materials derived from the modified MDA. The addition of a single methyl substituent, methoxy substituent, location of these substituents, and location of the amine relative to the phenolic bridge were modified as were other non-aniline diamines. Various anilines were condensed with paraformaldehyde under acidic conditions to yield dianilines. These dianilines and diamines were reacted with nadic anhydride and 3,3′,4,4′-benzophenonetetracarboxylic dianhydride in methanol to form the polyamic acid oligomers and heated at elevated temperature to form polyimide oligomers. It was found that the molecular weight of the oligomers derived from MDA alternatives was generally lower than that of MDA oligomers resulting in lower glass transition temperatures (T gs) and degradation temperatures. Additionally, methoxy substituents further reduce the T g of the polymers versus methyl substituents and reduce the thermal stability of the resin. Methyl-substituted alternatives produced polyimides with similar T gs and degradation temperatures. The toxicity of the MDA alternatives was examined. Although a few were identified with reduced toxicities, the alternatives with properties similar to that of MDA also had high toxicities.
