Machine Learning Assessment of Dredging Impacts on the Phytoplankton Community on the Brazilian Equatorial Margin: A Multivariate Analysis.

Dredging in estuarine systems significantly impacts phytoplankton communities, with suspended particulate matter (SPM) and dissolved aluminum (Al) serving as indicators of disturbance intensity. This study assessed the effects of dredging in the São Marcos Estuarine Complex (SMEC), Brazil, over three distinct events (2015, 2017, 2020), involving varying sediment volumes and climatic influences. Prolonged dredging operations and increased sediment volumes led to a pronounced 43.

Single Particle Dynamics at the Free Surface of Imidazolium-Based Ionic Liquids.

In this work, we carry out a systematic computer simulation investigation of the single particle dynamics at the free surface of imidazolium-based room temperature ionic liquids by applying intrinsic surface analysis. Besides assessing the effect of the potential model and temperature, we focus in particular on the effect of changing the anion type, and, hence, their shape and size. Further, we also address the role of the length of the cation alkyl chains, known to protrude into the vapor phase, on the surface dynamics of the ions.

G.T.A.R.A. : A Randomized Controlled Trial Using Guitar Lessons for Restoring Hand Function among Patients with Unilateral Hand Impairment.

Objective: To determine the effects of guitar lessons (intervention group) in comparison to conventional occupational therapy (OT) sessions (control group) on hand function of chronic stroke patients with unilateral hand impairment.

Methods: This randomized controlled trial enrolled 34 chronic stroke patients with unilateral hand impairment. Participants were grouped randomly into intervention (guitar lessons) and control (conventional occupational therapy) groups.

Eight weeks of Pilates Method improves physical fitness and sleep quality of individuals with post-COVID-19 syndrome: A randomized clinical trial blinded.

Objectives: To evaluate the impact of eight weeks of Pilates Method on physical fitness and sleep quality of individuals with post-COVID-19 syndrome.

Methods: Randomized clinical trial blinded conducted with fifty-nine individuals with post-COVID-19 syndrome. The participants were randomly allocated to the Pilates group (PG; n = 20), supervised physical exercise group (SPEG; n = 20) and control group (CG; n = 19).

Theoretically grounded approaches to account for polarization effects in fixed-charge force fields.

Non-polarizable, or fixed-charge, force fields are the workhorses of most molecular simulation studies. They attempt to describe the potential energy surface (PES) of the system by including polarization effects in an implicit way. This has historically been done in a rather empirical and ad hoc manner.
