X-ray high-resolution diffraction using refractive lenses [PDF]
, 2005 Refractive x-ray lenses have recently been applied for imaging and scanning microscopy with hard x rays. We report the application of refractive lenses in an optical scheme for high-resolution x-ray diffraction, performed at a high brilliance synchrotron

Microfluidic Contact Lenses [PDF]
Small, 2018 AbstractContact lens is a ubiquitous technology used for vision correction and cosmetics. Sensing in contact lenses has emerged as a potential platform for minimally invasive point‐of‐care diagnostics. Here, a microlithography method is developed to fabricate microconcavities and microchannels in a hydrogel‐based contact lens via a combination of laser

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

A seven square degrees survey for galaxy-scale gravitational lenses with the HST imaging archive
, 2014 We present the results of a visual search for galaxy-scale gravitational lenses in nearly 7 square degrees of Hubble Space Telescope (HST) images. The dataset comprises the whole imaging data ever taken with the Advanced Camera for Surveys (ACS) in the ...

Proceedings of the 26nd 2014 International Symposium on Implementation and Application of Functional Languages, 2014 Most complex applications inevitably need to maintain dependencies between subsystems based on some shared data. The dependent parts must be informed that the shared information is changed. As every actual notification has some communication cost, and every triggered task has associated computation cost, it is crucial for the overall performance of the

Proceedings of the National Academy of Sciences, 2013 Since Galileo, the arrays of lenses in telescopes have revolutionized the way we see planets, moons, and the universe. Now gravitational lenses made of warped spacetime are helping astronomers peer into the farthest corners of the cosmos.

Cross-correlatingPlanckCMB lensing with SDSS: lensing–lensing and galaxy–lensing cross-correlations [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We present results from cross-correlating Planck CMB lensing maps with the Sloan Digital Sky Survey (SDSS) galaxy lensing shape catalog and BOSS galaxy catalogs. For galaxy position vs. CMB lensing cross-correlations, we measure the convergence signal around the galaxies in configuration space, using the BOSS LOWZ ($z\sim0.30$) and CMASS ($z\sim0.57 ...
