Methamphetamine (METH) is a highly addictive psychostimulant, and despite its widespread abuse, there are no FDA-approved treatments for METH use disorder (MUD). Cannabidiol (CBD), a non-psychoactive cannabinoid, has shown promise in reducing behaviors linked to psychostimulant use, including METH. However, the underlying neurobiological mechanisms remain unclear.

Understanding interactions between chiral active particles- self-propelling and self-rotating entities- is crucial for uncovering how chiral active matter self-organizes into dynamic structures. Although fluctuation-induced forces in nonequilibrium active systems can drive structure formation, the role of chirality remains largely unexplored. Effective fluctuation-induced forces between intruders immersed in chiral active fluids are investigated and revealing that the impact of chirality depends sensitively on particle shape.

Neocortical circuits consist of multiple neuronal cell types, each likely playing distinct roles in flexible behavior. However, studies of decision-making have often overlooked these cell types, limiting our understanding of their specific contributions to local circuit functions. To address this, we simultaneously recorded neuronal activity from the frontal eye field (FEF), lateral PFC, and lateral intraparietal area (LIP) in a macaque monkey performing a visuomotor decision-making task.

Scene context is known to significantly influence visual perception, enhancing object recognition particularly under challenging viewing conditions. Behavioral and neuroimaging studies suggest that high-level scene information modulates activity in object-selective brain areas through top-down mechanisms, yet the underlying mechanism of this process remains unclear. Here, we introduce a biologically inspired context-based computational model (CBM) that integrates scene context into object recognition via an explicit feedback mechanism.

This study investigates the thermodynamic behavior of a two-qubit quantum system, where each qubit is coupled to an independent thermal reservoir, either bosonic or fermionic. Using a master equation approach, we analyze both steady-state and time-dependent ergotropy to understand how different reservoir statistics affect work extraction. In bosonic environments, ergotropy consistently declines with increasing temperature due to thermal noise.

The first search for a heavy neutral spin-1 gauge boson (Z^{'}) with nonuniversal fermion couplings produced via vector boson fusion processes and decaying to tau leptons or W bosons is presented. The analysis is performed using LHC data at sqrt[s]=13 TeV, collected from 2016 to 2018 with the CMS experiment and corresponding to an integrated luminosity of 138 fb^{-1}. The data are consistent with the standard model predictions.

We theoretically investigate the low-temperature magnetic and quantum properties of hexanuclear Fe[Formula: see text] complexes under an external magnetic field. We primarily study the impact of competing exchange interactions and their asymmetries induced by the Jahn-Teller distortion on the quantum properties of the complexes. The inequality in exchange interactions lifts the ground-state degeneracy that gives rise to complex quantum behavior.

We investigate the coherent control of anisotropic surface plasmon polaritons (SPPs) in a symmetric double-layer metal/uniaxial dielectric structure. The directional anisotropy introduced by the uniaxial dielectric enables tunable SPP dispersion, absorption, and propagation characteristics through an external control field. We analyze reflection and transmission spectra, dispersion relations, propagation lengths, and the scattering matrix eigenmodes.

The question of whether or not passive subwavelength cavities can alter the properties of quantum materials is currently attracting a great deal of attention. In this article, we show that the Fermi liquid parameters of a two-dimensional metal are modified by cavity polariton modes, and that these changes can be monitored by measuring a paradigmatic magneto-transport phenomenon, Shubnikov-de Haas oscillations in a weak perpendicular magnetic field. This effect is intrinsic, and totally unrelated to disorder.

Individuals with Internet addiction disorder (IAD) exhibit deficits in cognitive control, particularly in interference control; however, the behavioural and neural mechanisms underlying these impairments remain unclear. In this study, classic and modified Stroop tasks were administered to individuals with IAD and healthy control (HC) participants, whereas electroencephalography (EEG) was recorded. We hypothesized that individuals with IAD would demonstrate impaired interference control, as evidenced by longer reaction times (RTs) on incongruent trials and that these behavioural deficits would be accompanied by reduced ERP activity in both early and late medial frontal negativity (MFN) components, as well as diminished conflict slow potential (SP).

Working memory (WM) relies on brain networks including the prefrontal cortex (PFC) and medial temporal lobe (MTL) as key nodes. Graph theory analysis has recently played an important role in uncovering brain connectivity architectures due to its ability to characterize complex brain networks. Yet, it remains unclear whether the PFC and MTL exhibit distinct effective connectivity patterns during information processing in WM.

We consider the dynamics of pore-driven polymer translocation through a nanopore to a two-dimensional semi-infinite space when the chain is initially confined and equilibrated in a narrow channel. To this end, we use Langevin dynamics (LD) simulations and iso-flux tension propagation (IFTP) theory to characterize local and global dynamics of the translocating chain. The dynamics of the process can be described by the IFTP theory in very good agreement with the LD simulations for all values of confinement in the channel.

This study used functional MRI data from the StudyForrest dataset to investigate the role of subnetworks of the default mode network (DMN) during naturalistic stimulus transitions of different types and magnitudes. We found distinct activation profiles within the DMN: the dmPFC subnetwork was specifically associated with social and location transitions, the MTL subnetwork preferred location and temporal transitions, while the Core DMN subnetwork responded to all three transition types. The multiple-demand network instead responded selectively to temporal transitions.

It is still an open question if magnetoelectric coupling occurs at the atomic scale in multiferroic BiFeO_{3}. Nuclear solid-state techniques monitor local fields at the atomic scale. Using such an approach, we show that, contrary to our own expectation, ferroelectric and magnetic ordering in bismuth ferrite (BiFeO_{3} or BFO) decouple at the unit-cell level.
