Summary: In patients with airway obstruction, an increase in breathing frequency at rest is commonly associated with dynamic hyperinflation. This study simulated airway obstruction in healthy subjects and found that an increase in respiratory rate during obstruction led to a paradoxical response with dynamic hyperinflation emergence while intercostal muscle oxygenation was preserved.

Summary: Llama fibre production in the Puna region of Argentina has significant potential, but quality analysis systems are still inadequate. This study evaluated the feasibility of using near infrared reflectance spectroscopy to assess fibre diameter, showing promising results as a sustainable, fast and low-cost method for quality validation.

Summary: The study aimed to test the feasibility of near-infrared spectroscopy (NIRS) monitoring of the human temporal muscle. It observed the hemodynamic changes in the muscle and brain during teeth clenching and hyperventilation in healthy subjects. The results demonstrated that this technique is suitable for monitoring tissue oxygenation and hemodynamic changes in the human temporal muscle.

Summary: Penguins have evolved increased hemoglobin-oxygen affinity and a significantly enhanced Bohr effect, allowing for more efficient oxygen extraction from the lungs and oxygen unloading in acidified tissues. This evolutionary adaptation enables penguins to fully utilize onboard oxygen stores and maximize underwater foraging time.

Summary: Exercise intolerance following allo-HSCT is associated with pulmonary dysfunction and muscle oxidative dysfunction, potentially due to impaired tissue oxygen transport. These findings could help identify the physical function associated with exercise intolerance in patients post allo-HSCT.

Summary: Research on fatty acids in beef using NIRS showed that it is a feasible and useful tool for assessing total fatty acid composition and phospholipid fraction. The study found that the variation in fatty acid concentration across animals provided good data for analysis, with models showing better performance for neutral lipids compared to phospholipids.

Summary: The study found that cerebral oxygenation variability and brain hemodynamic variability increased during maximal voluntary muscle exertions, indicating vascular recruitment to maintain brain oxygen homeostasis. Interestingly, despite similar levels of cerebral oxygenation variability compared to young individuals, brain hemodynamic variability was significantly higher in adults aged over 50, suggesting a significant cost of amplifying hemodynamic oscillation to maintain stable oxygenation in the aging brain.

Summary: Photonic-based implementation of advanced computing tasks is a potential alternative to overcome the limitations of electronics in terms of bandwidth. Despite their large bandwidth advantage, photonic systems are generally bulky and consume high power. In this study, we presented a fiber Bragg grating-based phase filter with a record frequency resolution of 1 GHz, which is a significant improvement compared to conventional optical waveshapers. The demonstrated high-speed passive logic operations using the all-fiber phase filter show promising potential for compact and low-energy-consuming signal processors.

Summary: The aim of this study was to investigate the effect of fibre type on the fatty acid composition and lipid oxidation in dry-cured ham. The results showed that wild boar meat had a higher percentage of monounsaturated fatty acids (MUFA) but lower levels of polyunsaturated fatty acids (PUFA) and saturated fatty acids (SFA) compared to deer meat. Furthermore, wild boar meat was more susceptible to oxidative changes. On the other hand, fallow deer meat had the highest percentage of saturated fatty acids (SFA) and the lowest levels of MUFA and PUFA.

Summary: The Hybrid seeding algorithm significantly improves the efficiency of charged particle reconstruction by utilizing the knowledge of the LHCb magnetic field and the position of energy deposits in the scintillating fibre tracker detector. It also achieves a low fake rate and makes a small contribution to the overall timing budget of LHCb real-time data processing.

Summary: This study focused on manufacturing composite material laminates using the Markforged continuous filament fabrication technique with carbon nanofiber matrix infilled Onyx. Various samples were tested to evaluate the influence of fibers on mechanical properties of composites and the effect of process parameters on 3D-printed sample quality and mechanical behavior through tests such as SEM analysis, tensile and compression tests, and thermogravimetric analysis.

Summary: Ageing is associated with reductions in skeletal muscle size and function, especially in fibres expressing fast myosin heavy chain isoforms. Lifelong aerobic exercise training is insufficient to prevent decrements in fast fibre contractile function. Further research is needed to investigate the effectiveness of other strategies, such as resistance training, to preserve fast fibre size and function with ageing. Integrating single fibre contractile mechanics with other important parameters is necessary to fully understand the ageing skeletal muscle phenotype.

Summary: Muscle fiber characteristics (MFCs) are important for lean meat production and meat quality. This study focused on the heritability and genetic correlation of MFCs and meat quality in biopsied and post-mortem meat samples of Jeju black pigs. The results showed high genetic correlation between biopsied and post-mortem samples, indicating that the MFCs of biopsied samples can predict the MFCs and quality of the meat after slaughter. The biopsy method can be useful for estimating MFCs and meat quality in live pigs.

Summary: This study investigated the effects of different plyometric training programs on speed, agility, and jumping performance in recreationally trained men. It was found that programs following different overload patterns but with equal training load showed similar performance effects. Additionally, low-intensity plyometric training is preferred over high-intensity training before competition to avoid a decline in performance.

Summary: The study found that W '(PRED) overestimated and underestimated W '(ACT) in the heavy- and moderate-intensity domain respectively. Therefore, the practical applicability of a single recovery time constant, which only relies on the difference between the recovery PO and the CP, is questionable.

Summary: This study utilized a machine learning model based on a broad range of variables to predict winning and losing in the highest Belgian soccer division. The model showed an accuracy of 89.6%, correctly classifying 516 out of 576 games, with shots on target being the best predictor. Physical indicators and contextual variables like ELO ratings were also identified as strong predictors.

Summary: The study demonstrated that W' recovery after exhaustion follows a two-phase exponential time course and is dependent on aerobic fitness. The appearance of a fast initial recovery phase was attributed to an enhanced aerobic energy provision resulting from changes in (V) over dotO(2) kinetics.

Summary: This study examined the cardiovascular and metabolic responses of dynamic dry apnea (DRA) and face immersed apnea (FIA). The findings indicate that FIA induced stronger bradycardia and lower lactate levels after the first apnea compared to DRA, while muscle oxygenation was not significantly different between the two conditions.
