We study the ground state of the spin-1/2 XXZ antiferromagnet on the triangular lattice in the easy-axis regime using density-matrix renormalization group with spiral boundary conditions. The ordered state remains a nontrivial three-sublattice Y-like structure over a wide anisotropy range. Extrapolation shows incomplete sublattice polarization even in the Ising limit. Energy comparisons demonstrate that the Y state is favored over the up-down-down state, stabilized by quantum fluctuations from the degenerate Ising manifold.

A review published in Thermo-X examines how thermal switches and thermal diodes could provide this dynamic control and enable new approaches to thermal management in energy and information technologies.

Researchers at the University of Science and Technology of China have developed an ultra-thin spray cooling heat sink only 3.5 mm thick and experimentally demonstrated its performance on a silicon-based thermal test chip. The study was published in Thermo-X.

Irinotecan is widely used for advanced solid tumours, but neutropenia (NP) remains a major dose‑limiting toxicity. This review summarises the pathogenesis, risk factors, and management of irinotecan‑induced neutropenia (IIN). IIN is primarily driven by SN‑38‑mediated topoisomerase I inhibition and mitochondrial injury in haematopoietic stem cells. Risk factors include irinotecan dosage, UGT1A and transporter gene polymorphisms, patient characteristics, organ function, and concomitant chemotherapy. Management strategies include genotype‑guided dosing, G‑CSF, alkalinising agents, and microbiota modulation. Integrating pharmacogenetics and supportive care may improve treatment safety and continuity.

The discovery of NFATC2 as a regulator of cellular “mechanical memory” could deepen understanding of cell migration in cancer metastasis, wound healing and fibrosis, while informing future tissue-engineering approaches.

A research team at City University of Hong Kong (CityUHK) has developed a new optical corner detection imaging method, which uses azimuthal Hilbert transform metasurfaces and is designed to work as a universal framework. The study marks an important advance in high-speed, low-power optical information processing and has demonstrated potential for motion tracking applications.
