FIRBACK Source Counts and Cosmological Implications [PDF]

, 2000
FIRBACK is a one of the deepest surveys performed at 170 microns with ISOPHOT onboard ISO, and is aimed at the study of cosmic far infrared background sources. About 300 galaxies are detected in an area of four square degrees, and source counts present a

CLASP Constraints on the Magnetization and Geometrical Complexity of the Chromosphere-Corona Transition Region

, 2018
The Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is a suborbital rocket experiment that on 3rd September 2015 measured the linear polarization produced by scattering processes in the hydrogen Ly-$\alpha$ line of the solar disk radiation, whose ...

Geostatistics: Modelling spatial variation

, 2023
Geostatistics, which was developed originally for mining, is now widely used for prediction of soil conditions at unvisited sites and for mapping from sample survey data. The technique is based on models of spatial variation. Soil properties are treated as the outcomes of random spatially correlated processes, to which may be added fixed effects of ...

Spatial variation in attributable risks [PDF]

Spatial and Spatio-temporal Epidemiology, 2015
The attributable risk (AR) measures the contribution of a particular risk factor to a disease, and allows estimation of disease rates specific to that risk. While previous studies consider variability in ARs over demographic categories, this paper considers the extent of spatial variability in ARs estimated from multilevel data with confounders both at

Hyperspectral images segmentation: a proposal [PDF]

, 2009
Hyper-Spectral Imaging (HIS) also known as chemical or spectroscopic imaging is an emerging technique that combines imaging and spectroscopy to capture both spectral and spatial information from an object. Hyperspectral images are made up of contiguous

Nanoparticle‐Based Tolerogenic Vaccines: Next‐Generation Strategies for Autoimmune and Allergic Disease Therapies

Angewandte Chemie International Edition, EarlyView.
Nanoparticle‐based tolerogenic vaccines harness controlled antigen delivery and immunomodulation to establish tolerance in autoimmunity and allergy. This review outlines how nanoparticle design (size, shape, composition, administration route) influences biodistribution and immune‐cell targeting.
