Exoplanet science with the LBTI: instrument status and plans [PDF]

SPIE Proceedings, 2015
The Large Binocular Telescope Interferometer (LBTI) is a strategic instrument of the LBT designed for high-sensitivity, high-contrast, and high-resolution infrared (1.5-13 $ $m) imaging of nearby planetary systems. To carry out a wide range of high-spatial resolution observations, it can combine the two AO-corrected 8.4-m apertures of the LBT in ...

Expression and ultrastructural localization of plasmin(ogen) in the terminally differentiated layers of normal human epidermis. [PDF]

Int J Cosmet Sci, 2019
There exists a paucity of data on the subcellular localization of plasmin(ogen) within normal human epidermis. Immunoelectron transmission electron microscopy labelling revealed that the inflammatory serine protease is located in the terminally differentiated keratinocytes and was largely associated with the corneocyte envelopes and to some extent with

Improving primary health care quality for refugees and asylum seekers: A systematic review of interventional approaches

Health Expectations, Volume 25, Issue 5, Page 2065-2094, October 2022., 2022
Abstract Background It has been widely acknowledged that refugees are at risk of poorer health outcomes, spanning mental health and general well‐being. A common point of access to health care for the migrant population is via the primary health care network in the country of resettlement.

A two-band approach to nλ phase error corrections with LBTI's PHASECam [PDF]

Optical and Infrared Interferometry and Imaging VI, 2018
PHASECam is the Large Binocular Telescope Interferometer's (LBTI) phase sensor, a near-infrared camera which is used to measure tip/tilt and phase variations between the two AO-corrected apertures of the Large Binocular Telescope (LBT). Tip/tilt and phase sensing are currently performed in the H (1.65 $ $m) and K (2.2 $ $m) bands at 1 kHz, and the K ...

Review article: latent tuberculosis in patients with inflammatory bowel diseases receiving immunosuppression—risks, screening, diagnosis and management

Alimentary Pharmacology &Therapeutics, Volume 56, Issue 1, Page 6-27, July 2022., 2022
Tuberculosis infection is of paramount relevance to the IBD population given the frequent use of immunosuppressive medications. Diagnosing latent tuberculosis infection provides a window of opportunity for treatment. The risks of reactivation with immunosuppressive therapy must be weighed against the risk of side effects, inconvenience of treatment and

L'-band AGPM vector vortex coronagraph's first light on LBTI/LMIRCam [PDF]

SPIE Proceedings, 2014
We present the first observations obtained with the L'-band AGPM vortex coronagraph recently installed on LBTI/LMIRCam. The AGPM (Annular Groove Phase Mask) is a vector vortex coronagraph made from diamond subwavelength gratings. It is designed to improve the sensitivity and dynamic range of high-resolution imaging at very small inner working angles ...

The LBTI Fizeau imager – I. Fundamental gain in high-contrast imaging [PDF]

Monthly Notices of the Royal Astronomical Society, 2017
We show by numerical simulations a fundamental gain in contrast when combining coherently monochromatic light from two adaptive optics (AO) telescopes instead of using a single stand-alone AO telescope, assuming efficient control and acquisition systems at high speed.

Searching for Faint Exozodiacal Disks: Keck Results and LBTI Status [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractThe possible presence of dust in the habitable zone around nearby main-sequence stars is considered as a major hurdle toward the direct imaging of Earth-like extrasolar planets with future dedicated space-based telescopes (e.g., Roberge et al. 2012).

The Exozodiacal Dust Problem for Direct Observations of ExoEarths [PDF]

, 2012
Debris dust in the habitable zones of stars - otherwise known as exozodiacal dust - comes from extrasolar asteroids and comets and is thus an expected part of a planetary system.
