Respiration-Locking of Olfactory Receptor and Projection Neurons in the Mouse Olfactory Bulb and Its Modulation by Brain State

Frontiers in Cellular Neuroscience, 2020
For sensory systems of the brain, the dynamics of an animal’s own sampling behavior has a direct consequence on ensuing computations. This is particularly the case for mammalian olfaction, where a rhythmic flow of air over the nasal epithelium entrains ...

Advances in imaging chest tuberculosis: blurring of differences between children and adults [PDF]

, 2009
This article reviews the ongoing role of imaging in the diagnosis of tuberculosis (TB) and its complications. A modern imaging classification of TB, taking into account both adults and children and the blurring of differences in the presentation patterns,

Interactions of Symbiotic Partners Drive the Development of a Complex Biogeography in the Squid-Vibrio Symbiosis

mBio, 2020
Microbes live in complex microniches within host tissues, but how symbiotic partners communicate to create such niches during development remains largely unexplored.

Video-rate computational super-resolution and integral imaging at longwave-infrared wavelengths [PDF]

, 2017
We report the first computational super-resolved, multi-camera integral imaging at long-wave infrared (LWIR) wavelengths. A synchronized array of FLIR Lepton cameras was assembled, and computational super-resolution and integral-imaging reconstruction ...

Scratching the Surface: Bacterial Cell Envelopes at the Nanoscale

mBio, 2020
The bacterial cell envelope is essential for viability, the environmental gatekeeper and first line of defense against external stresses. For most bacteria, the envelope biosynthesis is also the site of action of some of the most important groups of ...

Imaging Biomarkers and Prevalence of Complex Aortic Plaque in Cryptogenic Stroke: A Systematic Review

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Complex aortic plaque (CAP) is a potential embolic source in patients with cryptogenic stroke (CS). We review CAP imaging criteria for transesophageal echocardiogram (TEE), computed tomography angiography (CTA), and magnetic resonance imaging ...

Analysis of a multi-frequency electromagnetic imaging functional for thin, crack-like electromagnetic inclusions

, 2013
Recently, a non-iterative multi-frequency subspace migration imaging algorithm was developed based on an asymptotic expansion formula for thin, curve-like electromagnetic inclusions and the structure of singular vectors in the Multi-Static Response (MSR)

Resolution limits of quantum ghost imaging [PDF]

, 2018
Quantum ghost imaging uses photon pairs produced from parametric downconversion to enable an alternative method of image acquisition. Information from either one of the photons does not yield an image, but an image can be obtained by harnessing the ...

Visual quantification of prostaglandin E2 discharge from a single cell

Cell Structure and Function, 2023
Calcium transients drive cells to discharge prostaglandin E2 (PGE2). We visualized PGE2-induced protein kinase A (PKA) activation and quantitated PGE2 secreted from a single cell by combining fluorescence microscopy and a simulation model.
