High‐Pressure Modulation of Breathing Kagome Lattice: Cascade of Lifshitz Transitions and Evolution of the Electronic Structure

open access: yesAdvanced Science, EarlyView.
External pressure directly tunes the breathing distortion of the kagome lattice in Fe3Sn2, suppressing it near 15 GPa and reversing it at higher pressures. This structural modulation drives a cascade of Lifshitz transitions, reconstructs the Fermi surface, strengthens electronic correlations and carrier localization, and modifies ultrafast electron ...

Effects of tai chi exercises

open access: yes, 2012
Tai Chi, or also called ‘Tai Chi Chuan’, originated in China about six hundreds years ago as a martial art, has slowly become a widely popular physical exercise due to known health benefits. Tai Chi practitioners believe that ‘Qi’ – the vital life energy,

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS‐CoV‐2 Variants

open access: yesAdvanced Science, EarlyView.
Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

Monolayer MoS2 With Ultrahigh Piezoelectricity: From ALD Dose Control to Device Performance

open access: yesAdvanced Science, EarlyView.
This study demonstrates that controlling precursor dosages in atomic layer deposition (ALD) serves to regulate ultrathin oxide quality, which in turn determines sulfurization behavior and MoS2 monolayer continuity. The resulting continuous, low‐defect monolayers enable improved piezoelectric performance and support a flexible slippage sensor, linking ...

Early Spatial and Contextual Coding Deficits in Hippocampal CA1 Precede Performance Decline in an Alzheimer's Disease Model

open access: yesAdvanced Science, EarlyView.
Two‐photon calcium imaging in behaving 5xFAD mice reveals early CA1 coding deficits before behavioral decline. Task‐related place cell activity and splitter cell trajectory coding are impaired, with reduced retrospective dominance and greater prospective weighting.

Palaeoproteomic Deconvolution of Physical and Genetic Collagen Mixtures

open access: yesAdvanced Science, EarlyView.
ClassiCOL_v2 uses a novel “peptide patching” framework that treats any collagen sample as a patchwork of peptide sequences derived from phylogenetically related species. This allows the algorithm to simultaneously resolve two previously intractable problems: multi‐species samples and/or database deficiencies.

The effects of different types of Tai Chi exercise on anxiety and depression in older adults: a systematic review and network meta-analysis

open access: yesFrontiers in Public Health
BackgroundThe body of evidence supporting the beneficial effects of Tai Chi in reducing anxiety and depressive symptoms in older adults is steadily increasing. Nonetheless, there remains a scarcity of studies directly comparing the clinical effectiveness
