In this work, we study the magnetocaloric effect (MCE) in a working substance corresponding to a square lattice of spins with possible orientations, known as the "-state clock model". When the -state clock model has Q≥5 possible configurations, it presents the famous Berezinskii-Kosterlitz-Thouless (BKT) phase associated with vortex states. We calculate the thermodynamic quantities using Monte Carlo simulations for even numbers, ranging from Q=2 to Q=8 spin orientations per site in a lattice.

However, no study has investigated the biomechanical consequences of MTL deficiency on the MMPR.
Hypothesis: (1) MTL deficiency leads to increased medial meniscus extrusion, (2) increased medial meniscus extrusion is correlated with increased compression and shear forces at the MMPR, and (3) MTL repair restores medial meniscus extrusion and MMPR forces to native levels.
Background: Athletes with decreased baseline neurocognitive function may experience noncontact anterior cruciate ligament (ACL) injury in unanticipated athletic situations. Many ACL injury prevention programs (IPPs) focus on improving closed-skill movements (eg, planned landing). However, the more open-skill movements (eg, unplanned reactive movements) required in unpredictable sports scenarios are commonly absent from ACL IPPs, and the acute effects of open-skill training on neurocognitive function remain unclear.

Although it covers various sectors, emulsifiers have had a notable impact on its development. Numerous products depend on these components, and continuous research has led to the creation of ever-better products.

Gradients of morphogens and their receptors typically set-up PCP, but whether non-molecular cues, akin to phototropism in plants, also play a part remains unknown. Here, we report that basal bodies of newborn photoreceptor cells in the mouse retina are positioned centrally on the apical surface but then move laterally during the first postnatal week, generating cell-intrinsic asymmetry in the retinal plane.
