Quantum entanglement between the degrees of freedom encountered in the classical world is challenging to observe due to the surrounding environment. To elucidate this issue, we investigate the entanglement generated over ultrafast timescales in a bipartite quantum system comprising two massive particles: a free-moving photoelectron, which expands to a mesoscopic length scale, and a light-dressed atomic ion, which represents a hybrid state of light and matter. Although the photoelectron spectra are measured classically, the entanglement allows us to reveal information about the dressed-state dynamics of the ion and the femtosecond extreme ultraviolet pulses delivered by a seeded free-electron laser. The observed generation of entanglement is interpreted using the time-dependent von Neumann entropy. Our results unveil the potential for using short-wavelength coherent light pulses from free-electron lasers to generate entangled photoelectron and ion systems for studying spooky action at a distance.

This AI-assisted review article offers a dual review: a book review of Living with Risk in the Late Roman World by Cam Grey, and a critical review of the current potential of large language models (LLMs), specifically ChatGPT's DeepResearch mode, to assist in thoughtful and scholarly book reviewing within risk science. Grey's book presents an innovative reconstruction of how communities in the late Roman Empire perceived and adapted to chronic environmental and societal risks, emphasizing spatial variability, cultural interpretation, and the normalization of uncertainty. Drawing on commentary from a human reviewer and a parallel AI-assisted analysis, we compare the distinct strengths and limitations of each approach.

Peripheral sensory neurons, once regarded merely as a passive route for nociceptive signals, are now acknowledged as active participants in solid tumor progression. This review explores how sensory neurons influence and are influenced by the tumor microenvironment (TME) through both chemical and electrical signaling, underscoring their pivotal role in the emerging field of cancer neuroscience. We summarize recent findings indicating that cancer-neuron interactions vary among different organs and experimental models, highlighting the ways in which various tumors recruit and reprogram sensory neurons to establish mutual communication loops that foster malignancy.

Background: Umbilical cord hemorrhage (UCH) is a rare but catastrophic obstetric emergency associated with nearly 50% fetal mortality, and its precise pathogenic mechanisms remain elusive in clinical practice. The pathophysiological cascade involves hemorrhagic expansion from ruptured umbilical vessels predominantly the umbilical vein which generates compressive forces on adjacent umbilical arteries within the constrained Wharton's jelly. This acute vascular compromise precipitates the sudden cessation of fetoplacental circulation, culminating in irreversible hypoxic-ischemic injury.

The lithium‑oxygen battery (LOB) has emerged as an appropriate candidate for next-generation power supply system, owing to the ultrahigh theoretical energy density (3480 Wh kg) and relatively low cost. However, some intrinsic challenges, including high redox overpotentials, limited rate capability, and poor cyclic life, continue to hinder the practical deployment of lithium‑ oxygen batteries. The fundamental limitations originate from sluggish oxygen reduction/evolution reaction (ORR/OER) kinetics and parasitic side reactions, which can be effectively mitigated by employing efficient cathode electrocatalysts.

While effective in explaining paradoxes in decision making and effects in cognitive psychology, such as conjunction, disjunction, order, and response replicability, it lacks a direct link to neural information processing in the brain. This study bridges neurophysiology, neuropsychology, and cognitive psychology, exploring how oscillatory neuronal networks give rise to QL behaviors.
