Summary: The study aimed to evaluate whether the Addenbrooke's cognitive examination III (ACE III) can detect cognitive impairment in patients with cerebellar damage and to show the cognitive impairment profile of these patients. The results showed that ACE III can be used as a sensitive screening tool to detect cognitive impairments in patients with cerebellar damage.

Summary: This article investigates the limits of focal-plane array (FPA) technology by studying a double-reflector antenna system with wide-angle scan capabilities. The proposed reflector configurations are analyzed in terms of maximizing effective isotropic radiated power (EIRP), minimizing the required total number of array elements for a wide-scan range, and determining the highest number of simultaneously active array elements of the phased-array feed. The presented configurations have the ability to operate within a scan range of up to +/- 30 degrees in azimuth (+/- 35 beamwidths scan) and +/- 3 degrees in elevation. Different optimizations are explored to build systems with varying performance in key operation parameters such as array size, EIRP, and the number of active array elements. A detailed analysis demonstrates the potential applicability of this concept in future millimeter-wave (mm-wave) applications.

Summary: This paper proposes an action-decoupled algorithm for hybrid action space, which abstracts the original agent into two agents containing only discrete or continuous action space. The discrete and continuous actions are executed simultaneously. The proposed algorithm, named AD-SAC, is optimized using Soft Actor-Critic (SAC) algorithm. Experimental results show that our algorithm outperforms other algorithms in terms of convergence and robustness in UAV path planning and gimbal scanning tasks.

Summary: Perception Action Coupling is influenced by motor experiences and age, with younger individuals showing lower performance in body perception compared to older groups. Incongruent actions interfere with perceiving others' postures, while congruent actions increase reaction time without improving accuracy. Evaluating perception action coupling may predict body representation maturity and dysfunction in neuro-developmental disorders.

Summary: Spectral detector dual-energy computed tomography (SDCT) is a useful imaging tool for assessing focal airway lesions. It provides iodine density maps, virtual monoenergetic images, and effective atomic number maps for better evaluation compared to conventional CT, aiding in the differentiation of benign vs malignant lesions. SDCT reconstructions can provide additional information to guide diagnosis or management of patients with indeterminate tracheal or bronchial lesions.

Summary: This study investigated perception-action integration processes in patients with functional neurological movement disorders (FMD) and found that patients had difficulties in reconfiguring previously established stimulus-response associations and exhibited altered modulation of neuronal activity clusters. These results indicate that perception-action integration processes are altered in FMD.

Summary: Malignant focal liver lesions (FLLs) are rare in the pediatric population, leading to limited understanding of these diseases. This paper discusses common pediatric malignant FLLs and highlights the importance of medical imaging features in the diagnosis and follow-up of these lesions. CEUS may be a promising option for characterizing indeterminate FLLs in pediatric patients without the risk of ionizing radiation.

Summary: This research focuses on the stability analysis and stabilization of nonlinear processes characterized by the Takagi-Sugeno fuzzy model with variable time delays. A new integral inequality lemma and a novel stability condition based on linear matrix inequalities were proposed, showing the superiority of the stability criterion and controller design approach over existing methods.

Summary: This study discusses the quantification of upper limb associated reactions during walking in patients with acquired brain injuries. The authors were able to quantify ARs during walking, but the calculated kinematic arm measures are not a direct measure of ARs, rather providing a quantification of overall deviation of arm posture or movement during gait.

Summary: This study aimed to investigate the independent effect of the curved carbon-fiber plate in the Nike Vaporfly 4% shoe on running economy and running biomechanics. The results showed that cutting the carbon-fiber plate and reducing the longitudinal bending stiffness did not significantly affect the energy savings in the Nike Vaporfly 4%. Biomechanical differences were observed in the metatarsophalangeal joint, indicating a limited role of the plate in the reported energy savings.

Summary: The recent rapid development of track spikes has led to record-breaking performances, raising questions about the role of super spikes in improving running performance. The specific contributions of new shoe innovations to track running performance are still unknown. Testing super spikes is challenging due to the difficulty in quantifying the metabolic energy demands of middle-distance running events.

Summary: This study investigated the effects of different stride frequencies on fascicle kinematics and forces of the triceps surae muscle. The results showed that lower stride frequencies led to shorter muscle fascicle lengths and increased demand for muscle force, resulting in higher whole-body energy expenditure. In contrast, higher stride frequencies had less impact on muscle kinematics and force production, suggesting that increased energy expenditure is more related to the cost of leg swing and force production.

Summary: This study investigates the impact of locomotor asymmetry on head stability and dynamic visual acuity. The results show that during adaptation, step length asymmetry increases, shock attenuation decreases, and head stability is reduced, with a slight decrease in dynamic visual acuity. However, these decrements are reduced in the later stage of the condition, highlighting the adaptive nature of locomotion and the visuomotor systems.

Summary: A century ago, Fenn found that faster muscle contractions lead to more energy liberation. However, the evidence for isometric muscle contractions being energetically cheaper than concentric contractions is mainly based on single fiber or isolated muscle studies. This study aimed to investigate whether this holds true for whole body metabolic rate by changing the contraction velocity of ankle plantar flexors.

Summary: Walking on a split-belt treadmill can change baseline step length asymmetry, but the underlying causes of this adaptation are difficult to determine. Effort minimization has been proposed as a driving force behind this adaptation, but human behavior does not replicate this when allowed to freely adapt. Simulation results suggest that effort minimization would involve substantial positive step length asymmetry, but the lack of this characteristic in human behavior indicates additional factors influencing motor control strategies.

Summary: This article examines functional tests for evaluating postural control deficits in children and summarizes the available assessment tools and their psychometric properties. The study found that currently only two functional tests encompass the entire construct of postural control. While reliability is generally good, validity results depend on the task, age, and pathology. Future research should focus on test batteries and particularly explore structural validity and responsiveness in different populations with strong study designs.
