Light QCD axion dark matter from double level crossings
The even light QCD axion called the ZN axion can both solve the strong CP problem and account for the dark matter (DM). We point out that the single and double level crossings can naturally take place in the mass mixing between the ZN axion and axionlike

Vibroisolation of railway crossings with the application of shape-memory elements [PDF]
This research presents existing problem of railway elements and motor –vehicle road elements at their intersections. The objects of simulation research were vehicles passing over a level crossing of automobile road and rail-transportation road. Objective

Field-induced level crossings in spin clusters: Thermodynamics and magneto-elastic instability
Quantum spin clusters with dominant antiferromagnetic Heisenberg exchange interactions typically exhibit a sequence of field-induced level crossings in the ground state as function of magnetic field.

Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Assessment of the accident rate coefficient at pedestrian railway crossings
The object of the study is pedestrian railway crossings, which are specially designed pedestrian paths across railway tracks intended to ensure the safe passage of pedestrians over railway infrastructure, including areas outside of official level ...

Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Level-Crossing Characteristics of an Actively Managed Buffer
In this paper, we examine a buffer with active management that rejects packets basing on the buffer occupancy. Specifically, we derive several metrics characterizing how effectively the algorithm can prevent the queue of packets from becoming too long ...

Magnetocaloric effect as a signature of quantum level-crossing for a spin-gapped system
Recent research dealing with magnetocaloric effect (MCE) study of antiferromagnetic (AFM) low dimensional spin systems have revealed a number of fascinating ground-state crossover characteristics upon application of external magnetic field.

Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
