Design of the iLocater Acquisition Camera Demonstration System

, 2015
Existing planet-finding spectrometers are limited by systematic errors that result from their seeing-limited design. Of particular concern is the use of multi-mode fibers (MMFs), which introduce modal noise and accept significant amounts of background ...

Mid-IR AGPMs for ELT applications [PDF]

, 2016
The mid-infrared region is well suited for exoplanet detection thanks to the reduced contrast between the planet and its host star with respect to the visible and near-infrared wavelength regimes.

Histones deacetylases in the epidermis: structure, functions and therapeutic implications

Frontiers in Epigenetics and Epigenomics
Histone deacetylases (HDACs) are key epigenetic regulators that catalyze the removal of acetyl groups from histones and non-histone proteins, thereby modulating chromatin accessibility and gene expression.

Risk factors and prognosis for latent tuberculosis infection in dialysis patients: A retrospective cohort study at a single tertiary care center

Seminars in Dialysis, Volume 37, Issue 1, Page 59-64, January/February 2024.
Abstract Introduction Recent studies report that latent tuberculosis infection (LTBI) may lead to an increased risk of cardiovascular disease (CVD) that led us to hypothesize that LTBI may play an important role in major adverse cardiovascular events (MACE) in dialysis patients. Methods A single‐center retrospective cohort study was conducted.

Life Beyond the Solar System: Space Weather and Its Impact on Habitable Worlds [PDF]

, 2018
The search of life in the Universe is a fundamental problem of astrobiology and a major priority for NASA. A key area of major progress since the NASA Astrobiology Strategy 2015 (NAS15) has been a shift from the exoplanet discovery phase to a phase of ...

Lower Limits on Aperture Size for an ExoEarth-Detecting Coronagraphic Mission

, 2015
The yield of Earth-like planets will likely be a primary science metric for future space-based missions that will drive telescope aperture size. Maximizing the exoEarth candidate yield is therefore critical to minimizing the required aperture.

The LBTI hunt for observable signatures of terrestrial systems (HOSTS) survey: a key NASA science program on the road to exoplanet imaging missions [PDF]

SPIE Proceedings, 2014
The Hunt for Observable Signatures of Terrestrial planetary Systems (HOSTS) program on the Large Binocular Telescope Interferometer (LBTI) will survey nearby stars for faint exozodiacal dust (exozodi). This warm circumstellar dust, analogous to the interplanetary dust found in the vicinity of the Earth in our own system, is produced in comet breakups ...

Directly Imaging Tidally Powered Migrating Jupiters

, 2014
Upcoming direct-imaging experiments may detect a new class of long-period, highly luminous, tidally powered extrasolar gas giants. Even though they are hosted by ~ Gyr-"old" main-sequence stars, they can be as "hot" as young Jupiters at ~100 Myr, the ...
