Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

open access: yesAdvanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Seroprevalence of human T-lymphotropic virus type 1 in Papua New Guinea and Irian Jaya measured using different Western blot criteria [PDF]

open access: yes, 2000
Background: Endemic foci of HTLV-1 carriers have been found in the world, however, the origin of HTLV-1 in humans is still unclear. Since a distinct type of virus strain was isolated from the Solomon Islands, detailed surveys on HTLV-1 prevalence in ...

Hippocampal Chandelier Cells Modulate Seizure Susceptibility and Severity

open access: yesAdvanced Science, EarlyView.
The axon initial segment (AIS), crucial for action potential initiation, serves as a prime locus for controlling network activity. Chandelier Cells (ChCs), evolved in the mammals, intricately target AISs, acting as gatekeepers for neuronal firing. Diminishing ChC input makes animals more prone to developing seizures, whereas fortifying this connection ...
