Authors: Kantha Rao Jalli , Madhusudhan Reddypogula , Babu Rao Thella 
Published: October 2024

Abstract
In this investigation, Al7075 aluminum alloy reinforced with Si3N4 particles (3, 6, 9, and 12 wt%) was used as reinforcements to manufacture composites through a stir-casting approach. The microstructural characteristics have shown significant grain refinement owing to the presence of Si3N4 particle distribution during the solidification. SEM micrographs confirm the uniform distribution of Si3N4 particles with considerably fewer particle agglomerations throughout the matrix alloy. The reinforcement particle cluster formation is relatively increased for increasing the Si3N4 content. The SEM and EDS analyses showed good integrity at the matrix–refinement interface with no interfacial compound formation. The mechanical properties, such as hardness (up to 118 BHN), tensile strength (up to 281 MPa), and yield strength (up to 178 MPa), were enhanced by 30.69% and 20.27%, respectively. The wear-rate and coefficient of friction of the composites were evaluated with increasing percentages of Si3N4 content. The average wear-rate of the composites is 0.019, 0.0085, 0.0075, and 0.0065 mm3/m, respectively, for the increased Si3N4 ceramic particulate content from 3 to 12 wt%, while the average COF of the composites is 0.45, 0.37, 0.32 and 0.28 respectively. With the addition of Si3N4 particulate content, the wear resistance performance of the composites at 30 N has shown up to 46% enhancement and increased from 0.0052 to 0.0103 mm3/m with the increasing sliding velocity from 1.5 to 3.5 m/s for varying Si3N4 particulate content from 3 to 12 wt%, while reducing the COF up to 65%, and from 0.43 to 0.27. Different wear mechanisms are characterized by identifying the typical features of wear on the SEM micrographs of the worn surfaces. The dominant wear mechanisms of the composites are typically observed as abrasion, oxidation, delamination and melt wear. The mechanism and behavior of composites under dry sliding conditions are analyzed through the construction of wear maps. The windows of wear mechanisms and progression in terms of load and sliding velocity for the composites with various wt% of Si3N4 content were identified, analyzed, and presented.

Published: October 2024

Abstract
Tremor is a rhythmic, involuntary oscillatory movement that severely affects some aspects of a patient's daily life. The use of wearable tremor-suppressing orthoses has become an effective, noninvasive treatment method for controlling tremors. This article summarizes recent developments in upper limb tremor suppression orthoses, aiming to provide a foundation for future research. By analyzing the working mechanisms, degrees-of-freedom (DOFs), weight, and tremor suppression effectiveness of various types of orthoses, the following conclusions are drawn: We found that differences in the working mechanism and the number of suppression directions are related to the weight of the device; weight, in turn, is a major factor affecting the comfort of the orthoses; and the combination of the number and weight of the damping direction affects the effect of the damping equipment. Balancing these three factors should be a key focus of future research. Moreover, researchers are placing greater emphasis on the comfort of the wearer during the development of these orthoses.
The Influence of Thermophysical Parameters on Thermal Runaway Characteristics for Pouch-Type Lithium-Ion Batteries
Authors: Huang Yan , Lv Min 
Published: October 2024

Abstract
The thermal variation during the temperature rise process of batteries is closely related to multiple physical parameters. Establishing a direct relationship between these parameters and thermal runaway (TR) features under abusive conditions is challenging using theoretical equations due to complex electrochemical and thermal coupling. In this paper, a high-temperature thermal runaway model of pouch-type lithium-ion battery is established through electrical-thermal coupled approach, demonstrating a good agreement between the simulation and experimental results. The results reveal distinct trends in thermal parameters of the early temperature rise, trigger time for TR, and peak temperature during TR process, for varying convective heat transfer coefficient, cell specific heat capacity, cell density, and cell thermal conductivity. Across various convective heat transfer coefficients, the rates of temperature increase, moments of TR, and peak temperatures within a battery emerge as the cumulative outcomes of competing processes of the intricate exothermic secondary reactions within the battery, and the heat transfer with the surroundings. Batteries with lower heat capacity exhibit reduced thermal inertia and heightened sensitivity to temperature changes. Alterations in the thermal capacity of a battery wield a profoundly significant impact upon the moment of thermal runaway within the battery. Enhancing the thermal conductivity yields limited improvements in heat dissipation during thermal runaway primarily due to the relatively small geometrical scale of the battery. Results of this paper can provide valuable insights for size optimization design, thermal management system optimization design, thermal runaway safety warning, and prevention of Lithium-ion batteries.

Published: October 2024

Abstract
In this work, the dynamics of a liquid film on the surface of NACA 0012 airfoil placed in a high-speed air flow is investigated. The findings complement previous results obtained on time averaged ligament behavior and droplet sizes generated by the same airfoil. Experimental studies were carried out to assess the film thickness, droplet shedding, and the dynamics of the sheet. In the present work, air velocities up to 175 m/s were used with water films flowing between 1.4 and 2.6 cm2/s. The water film was introduced onto one side of the airfoil surface through a series of 0.5 mm holes separated by 1 mm at a location 35 mm downstream of the leading edge of the vane. The results were obtained using four experimental tools. The first is a point measurement of the dynamic film thickness using a confocal laser induced fluorescence method. This spatially resolved measurement provides time resolved measurement of the instantaneous liquid film thickness at specific points on the vane surface. This is complimented by time averaged images of the film thickness on the entire vane surface. Third, high speed videos are obtained to study the accumulation and breakup of the liquid at the trailing edge of vane. Finally, laser diffraction and Phase Doppler interferometry were used to document the spray dynamics downstream of the vane. The results illustrate that the average film thickness decreases with air velocity and increases with the water flowrate. The results are consistent with the previous studies and suggest that the dominant frequency of liquid film wave, ligament breakup length, drop size and spray concentration increase with the air velocity and is modestly affected by water flowrate. Finally, design tools are provided to predict the average film thickness and dominant frequencies of the film thickness, ligament breakup, spray concentration and droplet average size.
“There’s No One-Size-Fits-All Approach”: Challenges and Strategies Coaching Preschooler Sport in Canada
Authors: Harlow Meghan , Fraser-Thomas Jessica 
Published: October 2024

Coaches are seminal figures within sport, playing a key role in youths’ development, particularly when their approach and practices suit the age and context in which they are coaching. However, little is known about coaches’ experiences within early years (<6) sport. This case study examined coaches’ experiences in early years sport, revealing challenges-faced and strategies drawn-upon for effective coaching. Semistructured interviews with 10 coaches (Mage = 37.8; 7 male) leading multisport, soccer, dance, rugby, hockey, and t-ball programming to children 2–5 years contributed insights. Key challenges included children’s resistance to participate and varied ability levels; however, these were mitigated by creative best practices focused on age-appropriate delivery (e.g., use of stories/imagination, “classroom” management). Notably, effective strategies were often offered by coaches from private and club-based programs, whereas community-based volunteer coaches received less age-specific training and resources and had more turnover. Broader societal-level challenges related to parental expectations and pressures were also discussed. Findings highlight early years sport as a unique context in which interpersonal and intrapersonal coaching knowledge appear most critical. Identified best practices may support early years sport coaches in their day-to-day roles while highlighting the importance of preparing all early years sport coaches to deliver effective age-appropriate programming.
What Do High-Performance Football Coaches Need to Know About the Coach–Athlete Relationship? Implications for Formal Coach Education
Authors: Newland Andrew , Cronin Colum , Cook Gillian , Whitehead Amy 
Published: October 2024

A high-quality coach–athlete (C–A) relationship improves athlete well-being and performance but has been underrepresented in formal coach education. Eleven football coaches, working in some of the highest profile positions in England, were interviewed. We investigate to what extent their formal coach education experiences influenced their understanding of the C–A relationship. We explore their perceptions of the knowledge, relating to the C–A relationship, that could be included in formal coach education courses. Semistructured interviews were conducted with 11 coaches. Inductive reflexive thematic analysis generated the following five themes: (a) an incongruence between the importance of the C–A relationship and its prominence in coach education, (b) interpersonal competencies and a progressive approach to the C–A relationship, (c) understand the unique needs of high-performance athletes, and (d) build a culture conducive to high-quality C–A relationships. Findings demonstrate the C–A relationship is underrepresented in the main English FA Coaching Pathway and provides insights into the knowledge that could be incorporated into courses to meet the needs of coaches. Future research should explore the athlete’s perspective, relating to the knowledge coaches require to develop high-quality C–A relationships within high-performance football settings.

Published: October 2024

Context: Social determinants of health including insurance type, income, race, and ethnicity have been shown to influence the utilization of physical therapy and recovery after an orthopedic injury. The influence of social determinants of health on the utilization of physical therapy and recovery from concussion is not well understood. Design: Prospective observational registry study in a specialty concussion program. Methods: Patients diagnosed with a concussion using the Postconcussion Symptom Inventory and the visio-vestibular examination (VVE) who were also referred to physical therapy were included. The main outcomes of interest were the number of days from referral to initial physical therapy evaluation and the number of physical therapy visits completed. Information related to patients’ age, race, ethnicity, sex, insurance type, and Child Opportunity Index was extracted from the registry. Multivariate and univariate regressions were used to assess the associations of each sociodemographic characteristic with the outcomes. Results: A total of 341 patients diagnosed with concussion between January 2017 and December 2023 met inclusion criteria. The average age was 14.77, and 64% were female. Patients’ age, race, ethnicity, insurance type, and Child Opportunity Index were not associated with days to evaluation or length of care in physical therapy. Higher PCSI scores in children under 12 years (coefficient: 0.17, 95% CI, 0.06–0.29) and female sex (coefficient: 1.2, 95% CI, 0.26–2.1) were associated with a longer course of care in physical therapy. Patients with an abnormal VVE score had on average 2.1 more physical therapy visits than those with a normal VVE score (coefficient: 2.1, 95% CI, 0.73–3.5). Conclusions: Higher PCSI scores in children, female sex, and higher VVE scores in general predicted a longer course of care in physical therapy. Implementation of a clinical care pathway for concussion care using the PCSI and the VVE may be one strategy to help mitigate systemic factors that might otherwise negatively influence access to physical therapy.

Published: October 2024

ABSTRACT

Cabotegravir intramuscular gluteal injection is approved for HIV treatment (with rilpivirine) and prevention. Thigh muscle is a potential alternative injection site. We aim to characterize cabotegravir pharmacokinetics and its association with demographics following intramuscular thigh injection in comparison with gluteal injection using population pharmacokinetic (PPK) analysis. Fourteen HIV-negative participants received 600 mg single thigh injection in phase 1 study 208832 and 118 participants with HIV received thigh injections 400 mg monthly 4× or 600 mg once-every-2-months 2× after ≥3 years of gluteal injections in phase 3b study ATLAS-2M provided 1,249 cabotegravir concentrations from 366 thigh injections and 1,998 concentrations from 1,618 gluteal injections. The established gluteal PPK model was modified by adding thigh injection compartment and fit to pharmacokinetic data following both gluteal and thigh injections, enabling within-person comparison in ATLAS-2M. Gluteal parameters were fixed. Similar to the gluteal absorption rate constant (KA
gluteal
), the thigh absorption rate constant (KA
thigh
) was slower in females than males and in participants with higher BMI. KA
thigh
was strongly correlated with KA
gluteal
(correlation coefficient 0.766), best described by the additive linear relationship KA
thigh
= KA
gluteal
+ 0.0002527 h
−1
. Terminal half-life of thigh injection was 26% (male) and 39% (female) shorter than gluteal injection. Relative bioavailability of thigh to gluteal was estimated to be 89.9%. The impact of covariates on cabotegravir exposure following thigh injections was ≤35%. In conclusion, cabotegravir absorption following thigh injection was correlated with, faster than, and 10% less bioavailable than gluteal injection, and correlated with sex and BMI. The cabotegravir thigh PPK model can inform dosing strategies and future study design.
Candida guilliermondii
fungemia: a 12-year retrospective review of antimicrobial susceptibility patterns at a reference laboratory and tertiary care center

Published: October 2024

ABSTRACT

The prevalence of invasive candidiasis caused by non-
albicans Candida
species is increasing.
Candida guilliermondii
is an infrequent cause of candidemia but has been associated with decreased susceptibility to triazoles. Clinical data related to the infection with
C. guilliermondii
are sparse. Our study evaluated the antifungal susceptibility testing (AST) for
C. guilliermondii
isolates submitted to a reference laboratory over a 12-year period (2012–2023). AST patterns were examined using Clinical and Laboratory Standards Institute (CLSI) and European Committee on Antimicrobial Susceptibility Testing (EUCAST) epidemiological cutoff values (ECVs) and breakpoints. Where isolates were identified from patients treated at our institution, retrospective chart review was performed to describe patient risk factors, treatment approaches, and outcomes associated with
C. guilliermondii
fungemia. One hundred twelve blood culture isolates of
C. guilliermondii
were identified, and clinical data were available for 21 fungemic patients. A significant number of isolates (9.8–20.5%) were observed to be non-wild type for various triazoles. All isolates were susceptible to micafungin. A majority (76.2%) of cases of
C. guilliermondii
fungemia treated at our tertiary care center were hospital-acquired, and two-thirds of patients were immunocompromised at the time of diagnosis. Ten of the 21 patients died within 60 days of fungemia, although mortality was directly or partially attributed to
C. guilliermondii
fungemia in only four cases (19.0%). Echinocandins may be used for empiric therapy for
C. guilliermondii
until the results of AST are available. Further research is required to determine appropriate clinical breakpoints for triazoles.

IMPORTANCE

Our study addresses a significant knowledge gap in the clinical management of this non-
Candida albicans
species. Our retrospective review includes comprehensive AST data for 112
Candida guilliermondii
isolates, which is the largest number of isolates reported from the United States to date. Susceptibility data are supplemented by clinical outcomes, where isolates were identified for patients treated at Mayo Clinic. Key findings from our study include the observation that a notable proportion of
C. guilliermondii
isolates exhibit non-wild-type profiles for various triazoles. Importantly, all isolates remained susceptible to echinocandins, suggesting their efficacy as first-line therapy in the absence of timely susceptibility results. Furthermore, our study highlights the high mortality associated with
C. guilliermondii
fungemia in immunocompromised patients, emphasizing the urgent need for optimized treatment strategies.
Crustal thickening and multipoint delamination for the ca. 90 Ma high-Sr/Y intrusions and the associated porphyry-skarn Cu-Au-Mo mineralization in the western central Lhasa terrane, Tibetan Plateau

Published: October 2024

Abstract
The ca. 90 Ma (92–84 Ma) high-Sr/Y intrusions in the western central Lhasa terrane (WCLT) of the Tibetan Plateau record critical information about the late Mesozoic crustal architecture of the Lhasa terrane and may have provided favorable conditions for porphyry mineralization. However, conflicting geodynamic processes have been proposed, and their mineralization potential is unclear. Here, we report the newly discovered Banongzuosi porphyry-skarn Mo-Cu deposit and Qielong skarn Cu-Au and Rongqing porphyry-quartz vein-type Mo mineral prospects. They provide important constraints on the generation of the ca. 90 Ma high-Sr/Y magmas and their associated mineralization potential. Then, integrated studies of the ca. 90 Ma intrusions are performed to address the above issues. Dating shows that intrusions and mineralization in the three areas occurred at 92.4–84.1 Ma. Based on whole-rock geochemistry, the high-Sr/Y intrusions can be divided into low- and high-Mg#-Cr ones. Zircon Hf isotopic data indicate that both ancient and juvenile lower crust existed in the WCLT, with significant juvenile components in the high-Mg# and Cr-rich intrusions. The crustal thickness calculated from the zircon trace element data suggests that the WCLT had thickened crust (&gt;64 km) with local areas thinned by lower crustal delamination at ca. 90 Ma. Regional thickening and local lower crustal delamination formed the low- and high-Mg#-Cr intrusions, respectively. Whole-rock and zircon trace element data reveal that most of the ca. 90 Ma high-Sr/Y intrusions are hydrous and oxidized. The thickened crust resulted in high H2O contents and fO2 of intrusions and promoted porphyry-skarn mineralization. However, crustal thinning and contamination by reduced Precambrian basement decreased the magma fO2 and hindered mineralization. The advantageous tectonic setting and high H2O and fO2 led to the ca. 90 Ma high-Sr/Y intrusions having the potential to form collisional porphyry-skarn Cu-Au-Mo deposits.
Underplating-induced trans-crustal melting and maturation of Neoarchean continental crust in the North China Craton
Authors: Yu Yang , Sun Guozheng , Li Sanzhong , Chen Yuelong , Gao Xiangyu 
Published: October 2024

Abstract
A global change in granitoid compositions from early predominantly sodic tonalite-trondhjemite-granodiorites (TTGs) to later TTGs and more potassic granites occurred during the late Archean, coupled with a major period of crustal maturation. However, the detailed relationship between granitoid chemical evolution and the maturing crustal process remains enigmatic. Successive granitoid magmatism including late Neoarchean TTGs and high-K granites occurred in the Western Shandong Province granite-greenstone belt (WSP) of the North China Craton and thus preserves crucial clues of the crustal maturation process. In this study, petrology, whole-rock geochemistry, and zircon U-Pb and Lu-Hf isotopes are reported for the late Neoarchean TTG gneisses, monzogranites, and minor metabasaltic to andesitic rocks from the WSP. The ca. 2560–2540 Ma TTG gneisses show low MgO, K2O/Na2O, but high (La/Yb)N, Sr/Y, and absence of Eu anomalies, indicating their derivation from partial melting of the thickened lower mafic crust. The ca. 2530–2500 Ma monzogranites are characterized by systematically high SiO2 and K2O/Na2O, but low MgO and Sr/Y, and moderately negative Eu anomalies, revealing they were formed by intracrustal reworking of local TTGs and sedimentary rocks in the middle to upper crust. Geochemical variations of these crustal-derived granitoids suggest that they were formed by melting at gradually higher crustal levels with the melt zone moved gradationally from the eclogite stability field into the plagioclase stability field. The ca. 2530–2500 Ma calc-alkaline metabasaltic to andesitic rocks sourced from metasomatized mantle outline roles of mantle-derived magma underplating in contributions of heating and trans-crustal melting magmatism. The long-term melting processes facilitated the upward movement of volatiles and heat-producing elements from deep to shallow crustal levels, and introduced K-enriched monzogranites into the upper crust, leaving a refractory, strengthening, and tectonically stable lower crust. Secular compositional evolution of crustal-derived granitoids reveals that continuous crustal reworking drove lithosphere differentiation and paved the way for the maturation of the Archean continental crust.
