Anomalous acoustic reflection on a sliding interface or a shear band

, 2003
We study the reflection of an acoustic plane wave from a steadily sliding planar interface with velocity strengthening friction or a shear band in a confined granular medium.

Space-Time Medium Functions as a Perfect Antenna-Mixer-Amplifier Transceiver

, 2020
We show that a space-time-varying medium can function as a front-end transceiver, i.e., an antenna-mixer-amplifier. Such a unique functionality is endowed by space-time surface waves associated with complex space-time wave vectors in a subluminal space ...

The effective conductivity of arrays of squares: large random unit cells and extreme contrast ratios [PDF]

, 2011
An integral equation based scheme is presented for the fast and accurate computation of effective conductivities of two-component checkerboard-like composites with complicated unit cells at very high contrast ratios.

Dendritic cells steering antigen and leukocyte traffic in lymph nodes

FEBS Letters, EarlyView.
Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the

Two-Pulse Propagation in Media with Quantum-Mixed Ground States

, 2007
We examine fully coherent two-pulse propagation in a lambda-type medium, under two-photon resonance conditions and including inhomogeneous broadening. We examine both the effects of short pulse preparation and the effects of medium preparation.

Leveraging current insights on IL‐10‐producing dendritic cells for developing effective immunotherapeutic approaches

FEBS Letters, EarlyView.
In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/

Use of Two-dimensional Multiple-slice Magnetic Resonance Hydrography for Diagnosis of Hepatic Hemangiomas and Cysts

Journal of the Formosan Medical Association, 2011
Although hepatic hemangiomas and cysts display very high signal intensities on conventional T2 images, their appearances are quite distinct using magnetic resonance hydrography (MRH).

Radiographic and ultrasonographic evaluation of the esophagus in the horse [PDF]

, 2016
The purpose of this study was to describe the radiographic and ultrasonographic appearance of the esophagus of ten healthy horses. Contrast radiography showed variations in the long-axis shape of the esophagus at the thoracic inlet.

Probing meson spectral functions with double differential dilepton spectra in heavy-ion collisions [PDF]

, 2000
The double differential dilepton spectrum $dN/ (dM_\perp^2 dM^2)$ at fixed transverse mass $M_\perp$ allows a direct access to the vector meson spectral functions.
