Summary: This study investigates the hydrodynamic role of manta-like bioinspired flapping through computational fluid dynamics simulations. The results show that the pectoral fin pitching ratio has significant implications in the thrust and efficiency of the manta model. Lower pitching ratios lead to more optimal vortex formation and shedding, while moderately high bending ratios can slightly reduce power consumption. By combining a moderately high bending ratio with a specific pitching ratio, further performance improvements can be achieved.

Summary: This study compared the outcomes of right-sided colon cancer (RCC) and left-sided colon cancer (LCC). The results showed no significant difference in overall survival or time to recurrence between patients with RCC and LCC. However, in stage II colon cancer patients, RCC was associated with shorter time to recurrence.

Summary: In heart failure, the mechanisms of right ventricular dysfunction are poorly understood. This study found that when exposed to chronic volume overload, both the right and left ventricles show similar upregulation of stress and metabolic markers. However, the right ventricle may have a relatively larger response to volume overload compared to the left ventricle, potentially due to concomitant pulmonary hypertension. No evidence supports chamber-specific regulation of protein expression in response to volume overload.

Summary: This study investigates the spatiotemporal changes in nitrogen dioxide (NO2) tropospheric vertical column density during the COVID-19 pandemic in six different countries. Significant declines in relative differences were observed in most countries, except for the US. The post-lockdown period saw a rebound in NO2 columns in most countries, except for India where the impact of COVID-19 continued to influence NO levels.

Summary: This study investigates the underlying mechanism for the differences between left ventricle (LV) and right ventricle (RV) using a modular modeling approach. The researchers developed a new integrative model by combining validated individual components of existing models and found that the ionic mechanisms play a role in the variation in force production between ventricles.

Summary: The female sex in patients with atrial fibrillation (AF) is a paradoxical risk factor for stroke, as it increases the risk among older women of certain ethnicities but contradicts the male predominance in cardiovascular diseases. Through simulations, it was found that this sex difference may be generated non-causally through left truncation due to competing risks (CR) such as coronary artery diseases. The study demonstrated that left truncation can identify spurious risk factors, and that female sex in patients with AF may be a paradoxical risk factor for stroke.

Summary: This study investigated the auditory characteristics of older and young adults and found that older participants had lower lateralization ability and both older and young participants showed reduced recognition of sound onset as the rise time increased. A significant right ear advantage was observed in young participants, but not in older participants, even with a prolonged rise time.

Summary: By using dynamic causal modelling and Parametric Empirical Bayes analyses applied to fMRI data, this study found that the connectivity patterns between bilateral regions in the grasping network are similar during executed grasping movements. However, during pantomimed grasping, interhemispheric crosstalk is mainly driven by premotor areas, with inhibitory influences from the right PMd towards the left premotor and motor areas and excitatory couplings between homologous ventral premotor and supplementary motor regions. Overall, the results suggest that unilateral grasping execution involves a non-lateralized set of brain areas complexly intertwined by interhemispheric dynamics, while motor imagery follows different principles.

Summary: This paper presents a method for extracting kinematic vocal fold parameters and estimating phase differences between the left and right vocal folds from videokymographic images. A fitting procedure was proposed to extract model parameters with acceptable performance. Assessment of phase difference showed moderate agreement among observers and ROC analysis demonstrated good prediction accuracies for clinical and synthetic corpora.

Summary: The article presents a new model of pulmonary circulation that can cause pulmonary congestion without left heart failure during cardiopulmonary bypass. This congestion is characterized by right and left heart output mismatching. The pathophysiological mechanism, clinical manifestations, diagnosis, differential diagnosis, and treatment of this pulmonary congestion are reviewed and discussed in the article.

Summary: This study finds that the splitting of the elliptic flow at finite rapidities in noncentral relativistic heavy ion collisions is a result of the nonzero directed flow. The magnitude and sign of this splitting could depend on various factors.

Summary: This study experimentally assessed the vertical level difference between normal and tilted vocal folds in the framework of unilateral vocal fold paralysis, exploring the impact of different camera view angles on oscillation frequency and identifying essential parameters to quantify angular asymmetry. The results showed a correlation between oscillation frequencies obtained through imaging and aerodynamic data, contributing to a better understanding of the influence of angular asymmetry on vocal fold vibration.

Summary: The study found that the progression of LVH in hypertension did not lead to abnormal LV systolic function, but afterload mismatch was observed in patients with LVHF. Exhaustion of preload reserve led to afterload mismatch in group III.

Summary: This article examines the dominance of European identities in contemporary European protests, even when activists strongly criticize European integration. It identifies the existence of strong European identities across the political spectrum, distinguishing between 'anti-nationalist Europeans' and 'pro-European nativists'.
