Magnetic Field Control Using an Electromagnetic Actuation System with Combined Air‐Core and Metal‐Core Coils

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
An electromagnetic manipulation system enhances magnetic field strength in the Z‐direction for 3D control of microrobots and nanoparticles. Featuring eight metal‐core coils and two air‐core coils arranged hemispherically, it ensures unimpeded workspace access and integrates imaging tools.

Nature of Phytoplankton Communities in the Southern Hemisphere Shallow Lakes, With an Emphasis on the Presence of Submerged Aquatic Vegetation: A Review

open access: yesAquaculture, Fish and Fisheries
Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding

A Novel Constitutional TUBB Variant Associated With Familial Malformations of Cortical Development

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Most pathogenic tubulin variants arise de novo in sporadic patients, causing severe brain malformations and significant neurodevelopmental impairment. The resulting reproductive disadvantage typically prevents these mutations from being transmitted to offspring.

Impacts of increasing anthropogenic aerosols on the atmospheric circulation trends of the Southern Hemisphere: An air-sea positive feedback

open access: yes, 2007
[1] A recent model study shows that in response to an increasing aerosol forcing, the Southern Hemisphere (SH) ocean circulation, including the Agulhas outflow, its retroflection, and the entire subtropical gyre circulation intensify and shift polewards.

Multimodal Characterization of Glymphatic‐Related Magnetic Resonance Imaging Markers in Huntington's Disease: A Multi‐Cohort Retrospective Study

open access: yesAnnals of Neurology, EarlyView.
Objective To characterize magnetic resonance imaging (MRI)‐based glymphatic surrogates in Huntington's disease (HD) using MRI measures of perivascular diffusivity and structural perivascular alterations across multiple large cohorts. Methods We analyzed 2,731 MRI sessions from 880 participants across 3 large retrospective HD cohorts.

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

A Global Climatology of Explosive Cyclones using a Multi-Tracking Approach

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2019
In this study, hemispheric climatologies of explosive cyclones (ECs) derived using a set of different cyclone detection and tracking methods (CDTMs) are analysed.
