Published: July 2008

The large deviation function for entropy production is calculated by solving a time-independent eigenvalue problem for a particle driven along a periodic potential. In an intermediate force regime, the large deviation function shows pronounced deviations from a Gaussian behavior with a characteristic "kink" at zero entropy production. Such a feature can also be extracted from the analytical solution of the asymmetric random walk to which the driven particle can be mapped in a certain parameter range.

Vibro-tactile stimulation of the neck induces head righting in people with cervical dystonia.

Parkinsonism Relat Disord

January 2025

Human Sensorimotor Control Laboratory, School of Kinesiology, University of Minnesota, USA; Center for Clinical Movement Science, University of Minnesota, USA.

Introduction: Cervical dystonia (CD) is characterized by involuntary neck muscle spasms that lead to abnormal head movements or postures. It is associated with somatosensory (tactile and proprioceptive) dysfunction. Here we tested whether vibro-tactile stimulation (VTS) of the cervical muscles constitutes a non-invasive form of neuromodulation of the somatosensory system that can provide temporary symptom relief for people with CD.

The detection of heavy metals in soil is of great scientific significance for food security and human health. However, traditional detection methods are complicated, time-consuming, and labor-intensive. Herein, we developed a novel method using Au@SiO nanoparticles (NPs) and surface microstructure combined with laser-induced breakdown spectroscopy (Au@SiO NPs-SMS-LIBS) for the rapid detection of lead (Pb), chromium (Cr), and copper (Cu) in soil samples.

Glufosinate (GLUF) and glyphosate (GLY) are nonselective phosphorus-containing amino acid herbicides that are widely used in agricultural gardens and noncultivated areas. These herbicides give rise to a number of key metabolites, with 3-methyl phosphinicopropionic acid (MPPA), -acetyl glufosinate (-acetyl GLUF), aminomethyl phosphonic acid (AMPA), -acetyl aminomethyl phosphonic acid (-acetyl AMPA), -acetyl glyphosate (-acetyl GLY), -methyl glyphosate (-methyl GLY) as the major metabolites obtained from GLUF and GLY. Extensive use of these herbicides may lead to their increased presence in the environment, especially aquatic ecosystems.

Quality of Psychiatric Care for Immigrants and People With a Non-English Language Preference: A Systematic Scoping Review.

Psychiatr Serv

January 2025

Department of Psychiatry, University of Colorado, Aurora (Singhal, Mause, Dempsey); Department of Medicine, University of California San Francisco, San Francisco (Garcia, Ochoa-Frongia); Clinical and Research Library, Children's Hospital Colorado, Aurora (St. Pierre).

Objective: Immigrants and persons with a non-English language preference (NELP) face unique challenges in the mental health care system. This systematic scoping review aimed to evaluate the literature for disparities in psychiatric care delivery, beyond access and utilization barriers, experienced by these two populations.

Methods: The authors queried four databases: PubMed, PsycInfo, Web of Science, and CINAHL.
