The work presents results of the diagnostics of travelling ionospheric disturbances (TIDs) over the Antarctic Peninsula obtained by using two different techniques. The first method is based on ground-based multi- positional GNSS TEC measurements, and the

An exploratory study of interpretability for face presentation attack detection
Biometric recognition and presentation attack detection (PAD) methods strongly rely on deep learning algorithms. Though often more accurate, these models operate as complex black boxes.

Modeling of GPS total electron content over the African low-latitude region using empirical orthogonal functions [PDF]
In this paper, an empirical total electron content (TEC) model and trends in the TEC over the African low-latitude region are presented. GPS-derived TEC data from Malindi, Kenya (geographic coordinates 40.194∘ E, 2.996∘ S), and global ...

Intracerebral Hemorrhage Induces Monocyte TNF Signaling in Patients That Is Suppressed by BAF312
ABSTRACT Objective Intracerebral hemorrhage (ICH) causes high morbidity and mortality, with neurotoxic inflammation driven by infiltrating monocytes. This study is an in‐depth longitudinal examination of the immune response during the first week of ICH in the presence and absence of the immunomodulatory drug BAF312 (Siponimod).

Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Structure and function of Tec family kinase Itk
Itk is a member of the Tec family of kinases that is expressed predominantly in T cells. Itk regulates the T cell receptor signaling pathway to modulate T cell development and T helper cell differentiation, particularly Th2 differentiation.

MONITORING IONOSPHERIC VARIATION FOR A DEFINITE PERIOD TIME IN TURKEY [PDF]
Ionosphere has been studied by a number of scientists in recent years. Since GPS observations cannot provide TEC value directly, it can be estimated from combination of observations.

TEC anomalies—Local TEC changes prior to earthquakes or TEC response to solar and geomagnetic activity changes? [PDF]
Abstract A number of papers have reported on deviations of daily values of the maximum electron concentration of the ionospheric F 2 layer and/or total electron content (TEC) in the vicinity of an earthquake’s epicenter some time prior to the quake.

A three‐dimensional magnetic field sensor is realized in chiral W/CoFeB/MgO multilayers, where spin–orbit torques reversibly reconfigure homochiral stripe domains. The symmetry of the torque enables offset‐free in‐plane sensing, while the reproducible domain reconfiguration extends the linear out‐of‐plane range. An anomalous Hall readout delivers large‐

Morphology of GPS and DPS TEC over an equatorial station: validation of IRI and NeQuick 2 models [PDF]
We investigated total electron content (TEC) at Ilorin (8.50° N 4.65° E, dip lat. 2.95) for the year 2010, a year of low solar activity in 2010 with Rz = 15.8.
