Background/aims: To measure the Timed Up and Go (TUG), imagined TUG (iTUG), and the difference of time between these two tests (delta time) in 20 patients with relapsing-remitting multiple sclerosis (RRMS) and 20 healthy age-matched controls and to examine whether an association with cognitive functions, motor impairment, and behavioral changes can be determined.
Methods: The mean ± SD of TUG, iTUG and delta time were used as outcomes. Spatiotemporal gait parameters were recorded by a 12-camera optoelectronic system during straight walking at usual self-selected speed. Cognitive functions were assessed by a standardized neuropsychological examination.
Results: Patients performed the TUG slower than the controls (10.00 ± 1.70 s vs. 8.71 ± 1.04 s, p = 0.01, respectively). The TUG was correlated with gait parameters, cognitive functions, and behavior, whereas delta time was correlated only with cognitive functions.
Conclusion: TUG represents an interesting test to reveal subtle deficits in RRMS patients with low disability and is related to motor, cognitive, and behavioral functioning. Combining with the TUG, delta time could easily give additional information on specific cognitive functions in the assessment of patients with RRMS.

Arithmetic normalisation models for the effects of lipid on carbon stable isotope values in silver carp () tissue.

Invasive silver carp () threaten Mississippi River basin ecosystems due to their ability to outcompete native species. Stable carbon (δC) and nitrogen (δN) isotope analysis has been used to study how silver carp impact native ecosystems, but lipids in fish tissues commonly bias their δC values. Chemical lipid extraction and mathematical equations that normalise δC values for lipid content can account for this bias, but have not been assessed for silver carp.

Stable understory microclimates within undisturbed rainforests are often considered refugia against climate change. However, this assumption contrasts with emerging evidence of Neotropical bird population declines in intact rainforests. We assessed the vulnerability of resident rainforest birds to climatic variability, focusing on dry season severity characterized by hotter temperatures and reduced rainfall.

This paper explores the impacts of integrating AI into the teaching of Chinese Opera using a mixed-methods approach, examining performance, engagement, and psychological factors in students. A quasi-experimental design involving 199 participants over a one-year period was conducted, involving teaching with and without AI enhancement. Quantitative data, derived from standardized tests and analytics provided by AI platforms, were supported by qualitative data from interviews and observational studies.

In this paper, a cascade delta-sigma modulation (CDSM) scheme is proposed for OAM-MDM intensity modulation and direct detection (IM/DD) transmission. Different from the traditional DSM (TDSM) scheme, the scheme is divided into signal modulation and in-band noise modulation, in which the in-band noise modulation is used to further decrease the quantization noise generated in the signal modulation.

The Southern California Bight is an ecologically important region for many local and migratory fauna. We combine bulk and compound-specific amino acid stable isotope measurements in the skeletons of proteinaceous octocorals with new regional ocean modeling system model output to explore biogeochemical changes at two locations within the Bight - Santa Cruz Basin and Santa Barbara Channel. Separated by the Channel Islands, these sites display distinct oceanographic regimes.
