Penetrating 3-D Imaging at 4- and 25-m Range Using a Submillimeter-Wave Radar [PDF]

, 2008
We show experimentally that a high-resolution imaging radar operating at 576–605 GHz is capable of detecting weapons concealed by clothing at standoff ranges of 4–25 m.

Nonclassical measurement error in farmland markets with implications for Ricardian analysis

American Journal of Agricultural Economics, Volume 108, Issue 2, Page 599-629, March 2026.
Abstract Nonclassical measurement error threatens the validity of empirical economic models. We examine the extent to which land value measures that are commonly used in studies of the US farmland market are subject to nonclassical measurement error. We consider differences in county‐level land values from two popular data sources: (1) self‐reported ...

Spinor dynamics in an antiferromagnetic spin-1 thermal Bose gas [PDF]

, 2013
We present experimental observations of coherent spin-population oscillations in a cold thermal, Bose gas of spin-1 sodium-23 atoms. The population oscillations in a multi-spatial-mode thermal gas have the same behavior as those observed in a single ...

Genomic Prediction and Genome‐Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model

Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 342-353, March 2026.
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.

Acoustic Absorption of Mortar Composites with Waste Material

Archives of Acoustics, 2013
This paper presents an investigation about acoustic absorption of mortars with partial replacement of sand by waste (plywood formwork, rice husk, and thermoplastic shoe counters), examining different levels of replacement (0%, 5%, 10%, 25%, and 50%). The

Multi‐Omics Insights Into the Role of Fructooligosaccharides Supplementation in Alleviating Salpingitis in Laying Hens

Animal Research and One Health, Volume 4, Issue 1, Page 105-119, February 2026.
Multi‐omics analysis revealed that FOS supplementation increased the abundance of Phascolarctobacterium, GCA‐900066575, Shuttleworthia, Olsenella, Eubacterium_hallii_group while decreasing Alistipes. It also influenced the metabolism of S‐lactoylglutathione, p‐cresol glucuronate, 2‐phenylethanol glucuronide, propionic acid, dulcitol, and inhibited the ...

Automatic parameter update algorithm for regression models to estimate remaining useful life: Application in an offshore natural gas dehydration unit

The Canadian Journal of Chemical Engineering, Volume 104, Issue 2, Page 935-952, February 2026.
Abstract Remaining useful life (RUL) analysis of equipment prevents failures and assists in maintenance to address impending failures. To achieve this, the advancement of degradation can be measured through a determinant variable. This work presents a new methodology for estimating the number of remaining cycles (NRC), or RUL, of equipment in cyclic ...

GPI PSF subtraction with TLOCI: the next evolution in exoplanet/disk high-contrast imaging

, 2014
To directly image exoplanets and faint circumstellar disks, the noisy stellar halo must be suppressed to a high level. To achieve this feat, the angular differential imaging observing technique and the least-squares Locally Optimized Combination of ...

A First Look at the Auriga-California Giant Molecular Cloud With Herschel and the CSO: Census of the Young Stellar Objects and the Dense Gas [PDF]

, 2012
We have mapped the Auriga/California molecular cloud with the Herschel PACS and SPIRE cameras and the Bolocam 1.1 mm camera on the Caltech Submillimeter Observatory (CSO) with the eventual goal of quantifying the star formation and cloud structure in ...
