TEM10 homodyne detection as an optimal small displacement and tilt measurements scheme [PDF]
, 2006 We report an experimental demonstration of optimal measurements of small displacement and tilt of a Gaussian beam - two conjugate variables - involving a homodyne detection with a TEM10 local oscillator.

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Limit on the Detectability of the Energy Scale of Inflation [PDF]
Physical Review Letters, 2002 We show that the polarization of the cosmic microwave background can be used to detect gravity waves from inflation if the energy scale of inflation is above 3.2 times 10^15 GeV. These gravity waves generate polarization patterns with a curl, whereas (to first order in perturbation theory) density perturbations do not.

Timeline analysis and wavelet multiscale analysis of the AKARI All-Sky Survey at 90 micron [PDF]
, 2008 We present a careful analysis of the point source detection limit of the AKARI All-Sky Survey in the WIDE-S 90 $\mu$m band near the North Ecliptic Pole (NEP).

A Review of Photothermal Detection Techniques for Gas Sensing Applications
Applied Sciences, 2019 Photothermal spectroscopy (PTS) is a technique used for determining the composition of liquids, solids and gases. In PTS, the sample is illuminated with a radiation source, and the thermal response of the analyte (e.g., refractive index) is analyzed to ...

occumb: An R package for site occupancy modeling of eDNA metabarcoding data
Population Ecology, EarlyView.This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

The Limitations due to Exposure Detection Limits for Regression Models [PDF]
American Journal of Epidemiology, 2006 Biomarker use in exposure assessment is increasingly common, and consideration of related issues is of growing importance. Exposure quantification may be compromised when measurement is subject to a lower threshold. Statistical modeling of such data requires a decision regarding the handling of such readings.

Brazilian Journal of Radiation Sciences, 2023 According to the limit of detection (DL) presented in ISO 11929:2010, the International Organization for Standardization (ISO) abandoned the concept of minimum detectable amount (MDA) described in ISO 12790-1:2001. In this work we demonstrate and discuss
