Summary: This study evaluates the mechanical effect of Morton's extension as an orthopedic intervention in patients with bilateral foot pronation posture. It examines variations in hindfoot and forefoot prone-supinator forces during the stance phase of gait. The results indicate that the use of Morton's extension decreases the maximum force of pronation and increases supination of the subtalar joint.

Summary: Single-joint isometric and isokinetic knee strength assessment is crucial in strength training, physical therapy, and rehabilitation, but literature lacks standardized reference values. A systematic review of studies assessing isometric knee strength revealed differences in knee strength levels between genders and age groups, with adult females and older adults generally showing lower strength levels than adult males.

Summary: The study found that hip angle, muscle contraction mode, and velocity have an impact on isokinetic knee strength. Most parameters were lower in knee flexion and at 90 degrees of hip flexion. Furthermore, angle-specific analyses were found to be more accurate than conventional parameters in assessing knee strength.

Summary: A neural-drive method was developed to estimate finger forces, showing superior performance compared to the conventional EMG amplitude-based method. This approach provides a reliable neural decoding method for dexterous finger movements, with potential for robust neural-machine interface for intuitive control of robotic hands.

Summary: The study aimed to determine the role of flexion-extension radiographs in surgical decision making for patients with degenerative spondylolisthesis. Results showed that flexion-extension views may provide additional value for patients with slips less than 7 mm and no evidence of motion on standing radiographs versus MRI. In 90% of cases, information used for surgical planning can be obtained by comparing motion between supine MRI and upright lateral radiographs.

Summary: Montane amphibians in the southern Philippines are vulnerable to environmental changes. Habitat variables such as elevation, shrub foliar cover, and tree basal area play a significant role in determining the distribution patterns of montane amphibians. Endemism increases with elevation, highlighting the importance of incorporating functional traits in understanding amphibian distribution patterns and community assembly mechanisms.

Summary: In this paper, a primal-dual path following method, called SISDP, is proposed for tackling nonlinear semi-infinite semi-definite programs with infinitely many convex inequality constraints. The proposed method approximates the solution by following a path formed by the intersection of the semi-infinite feasible region and the interior of the semi-definite feasible region. The method demonstrates global weak convergence and fast local convergence. Numerical experiments show the efficiency of the proposed method.

Summary: In this study, we compare the abilities of quantum and classical physics in terms of randomness certification from partially characterized devices, and propose quantum and noncontextual semi-device independent protocols for random-number generation based on maximum-confidence discrimination. The results show that, without unambiguously identifying any input states, quantum devices can certify more randomness than noncontextual ones.

Summary: A mechanomyogram visualizes mechanical signals from the surface of a muscle during contraction. It offers a simpler setup compared to surface electromyography, with less susceptibility to sweat interference. A regression analysis method is proposed to estimate knee joint torque based on MMG signals, integrating responses from four sensor locations and focusing on acceleration response characteristics.

Summary: The paper proposes an extension of the Efficient Market Hypothesis that accommodates multiple-criteria decision analysis by using parametric signed dissimilarity measures to assess multidimensional performance differences, while presenting two novel theoretical results connecting different normalization techniques. This multicriteria extension provides a common framework for adding empirical evidence regarding the testing of the EMH.

Summary: Naive Bayes classifier is known for its simplicity and performance, but many generalizations compromise simplicity and lead to more complex models. The Multi Independent Latent Component Naive Bayes Classifier uses latent variables to maintain the model structure while reducing complexities in classification and learning. Experimental results show that it outperforms state-of-the-art classifiers in terms of AUC and ACC.

Summary: This study investigated crosstalk in mechanomyographic signals from elbow flexors during isometric muscle actions at varying effort levels. The results showed that crosstalk increased with higher muscle activity levels, with the magnitude varying among different muscle pairs and showing a high positive correlation with the crosstalk levels between biceps brachii and brachialis muscles.

Summary: This article introduces a double-acting soft actuator that combines tendon-driven flexion and pneumatic extension of fingers using a single motor. The actuator achieves this through a smart pulley and bellow system. Kinematic and torque models are developed to analyze the actuator's performance, and experimental studies characterize its bending angle and extension torque. A prototype soft glove is fabricated to demonstrate finger flexion and extension assistance, and its performance is evaluated using electromyography signals.

Summary: This study investigated the differences in hamstring electromyography (EMG) activity between simultaneous hip extension and knee flexion (HE-KF) and knee flexion alone (KF), finding higher EMG activity in certain muscle regions during HE-KF. Future research should explore whether this activity is linked to injury risk and sprint performance.
