The abrupt drop of resistance to zero at a critical temperature is a key signature of the current paradigm of the metal-superconductor transition. However, the emergence of an intermediate bosonic insulating state characterized by a resistance peak preceding the onset of the superconducting transition has challenged this traditional understanding. Notably, this phenomenon has been predominantly observed in disordered or chemically doped low-dimensional systems, raising intriguing questions about the generality of the effect and its underlying fundamental physics.

Disinfection by-products (DBPs) have received considerable focus due to potential teratogenic, carcinogenic, and mutagenic effects; however, there is an evident gap in the availability of analytical methodologies for the simultaneous determination of DBPs in fish, especially iodinated DBPs. This paper developed an innovative analytical method for the simultaneous determination of 12 DBPs, including four trihalomethanes (THMs), three haloacetonitriles, and five iodinated THMs (I-THMs), in fish muscle, utilizing solvent extraction followed by gas chromatography with electron capture detection. The method incorporates tert-butyl methyl ether as an extraction solvent, performing efficient vortex mixing, extraction, and centrifugation under reduced temperature conditions to facilitate the processing of physically disrupted fish tissues.

Structured beams carrying orbital angular momentum (OAM) provide powerful capabilities for applications in optical tweezers, super-resolution imaging, quantum optics, and ad-vanced microparticle manipulation. However, it is challenging for generate and control the OAM beams at the extreme ultraviolet (EUV) region due to the lack of suitable wave front shaping optics arise from being limited to the strong absorption of most materials. Here, we use a modified Fermat-spiral photon-sieve splitter to simultaneously generate two focused doughnut beams with opposite helical phase.

Superconductors based on transition metal dichalcogenides are of substantial current relevance towards the material realization of topological superconductivity. Here, we report a detailed study on the synthesis and characterization of single crystals of 2H-TaSeS. A superconducting transition is confirmed at4.

Article Synopsis
- The study aimed to explore the distribution and characteristics of choroidal vortex veins in patients with pachychoroid disease (PCD) through a retrospective observational design.
- Using wide-field indocyanine green angiography, researchers analyzed 190 eyes from 99 PCD patients, categorizing vortex veins by location (equatorial vs. posterior) and morphology (various completeness levels).
- Key findings revealed that 91.1% of eyes lacked posterior vortex veins, with the majority being equatorial and the most common type being incomplete; these insights are crucial for understanding the vascular aspects of PCD.
