Spectropolarimetric NLTE inversion code SNAPI

, 2018
Inversion codes are computer programs that fit a model atmosphere to the observed Stokes spectra, thus retrieving the relevant atmospheric parameters. The rising interest in the solar chromosphere, where spectral lines are formed by scattering, requires ...

Ground-based detections of thermal emission from CoRoT-1b and WASP-12b [PDF]

, 2011
We report a new detection of the H-band thermal emission of CoRoT-1b and two confirmation detections of the Ks-band thermal emission of WASP-12b at secondary eclipses. The H-band measurement of CoRoT-1b shows an eclipse depth of 0.145%\pm0.049% with a 3-{

Inverse monoids of dot-depth two

Theoretical Computer Science, 1989
The dot-depth hierarchy of star-free regular languages has been introduced by \textit{J. Brzozowski} and \textit{R. Cohen} [J. Comput. Syst. Sci. 5, 1-16 (1971; Zbl 0217.296)]. A variant has been considered by \textit{H. Straubing} [J. Pure Appl. Algebra, 36, 53-94 (1985; Zbl 0561.20042)]. Its level 0 consists of \(A^*\) and the empty set, and its \((n+

Magnetotelluric inversion for depth-to-basement estimation [PDF]

SEG Technical Program Expanded Abstracts 2015, 2015
The magnetotelluric (MT) method can be effectively applied for depth-to-basement estimation, because there exists a strong contrast in resistivity between a conductive sedimentary basin and a resistive crystalline basement. Conventional inversions of MT data are usually aimed at determining the volumetric distribution of the conductivity within the ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

A new approach for inversion of receiver function for crustal structure in the depth domain

Earth and Planetary Physics, 2022
A method for reconstructing crustal velocity structure using the optimization of stacking receiver function amplitude in the depth domain, named common conversion amplitude (CCA) inversion, is presented.

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

A Noise De-Correlation Based Sun Glint Correction Method and Its Effect on Shallow Bathymetry Inversion

Remote Sensing, 2022
Sun glint on the sea surface is the unavoidable noise in optical remote sensing images. Water depth retrieval based on optical remote sensing images is vulnerable to sun glint contamination.

First detection of the ground-state J_K = 1_0 → 0_0 submillimeter transition of interstellar ammonia [PDF]

, 1983
The J_K = 1_0 → 0_0 transition of ammonia at 572.5 GHz has been detected in OMC-1 from NASA's Kuiper Airborne Observatory. The central velocity of the line (V_(LSR)≈ 9 km s^(-1)) indicates that it originates in the molecular cloud material, not in the ...

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...
