A High‐Resolution Transcriptomic Atlas of Cell Types in the Ventral Visual Thalamus

Journal of Neurochemistry, Volume 170, Issue 3, March 2026.
Visual information from the eyes travels from retinal ganglion cells (RGCs) to reach the brain through several relay centers. One of these centers, the ventral lateral geniculate nucleus (vLGN), is much less understood than others. In this study, we created the first detailed map of the different cell types found in the mouse vLGN.

Biconical antennas with elliptical cross-sections

Electronics Letters, 2000
The methods of coordinate transformation and conformal mapping are applied to study the problem of radiation from a biconical antenna with elliptic cross section. The infinite elliptic cone geometry can be transformed into the two-dimensional plane under the assumption of pure TEM spherical waves.

Observations of Low Frequency Solar Radio Bursts from the Rosse Solar-Terrestrial Observatory

, 2012
The Rosse Solar-Terrestrial Observatory (RSTO; www.rosseobservatory.ie) was established at Birr Castle, Co. Offaly, Ireland (53 05'38.9", 7 55'12.7") in 2010 to study solar radio bursts and the response of the Earth's ionosphere and geomagnetic field. To

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 466-486, March 2026.
Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...

Biconical antennas with unequal cone angles [PDF]

IEEE Transactions on Antennas and Propagation, 1998
The problem of radiation and reception of electromagnetic waves associated with a spherically capped biconical antenna having unequal cone angles /spl psi//sub 1/ and /spl psi//sub 2/ is investigated. Both cones that comprise a bicone are excited symmetrically at the apices by a voltage source so that the only higher order modes are TM.

Evaluation of prediction accuracy for the Longley-Rice model in the FM and TV bands [PDF]

, 2013
Accurate geographical coverage predictions maps for FM and TV are needed for channel and frequency allocations and in order to avoid unwanted interferences.

Design and Initial Performance of the Askaryan Radio Array Prototype EeV Neutrino Detector at the South Pole

, 2011
We report on studies of the viability and sensitivity of the Askaryan Radio Array (ARA), a new initiative to develop a Teraton-scale ultra-high energy neutrino detector in deep, radio-transparent ice near Amundsen-Scott station at the South Pole.

How an antenna launches its input power into radiation: the pattern of the Poynting vector at and near an antenna [PDF]

, 2005
In this paper I first address the question of whether the seat of the power radiated by an antenna made of conducting members is distributed over the ``arms'' of the antenna according to -J .

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

Advanced Functional Materials, Volume 36, Issue 15, 19 February 2026.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Single and Multiple Scattering in UWB Bicone Arrays

International Journal of Antennas and Propagation, 2008
An analysis of interactions between radiators in a UWB biconical array, drawing attention to single and multiple scatterings, is carried out. The complementarity between electrical coupling and radiation scattering is argued.
