Forensic bruise documentation with alternate light sources: Preliminary observation on deceased individuals in a routine illuminated autopsy setting

Journal of Forensic Sciences, EarlyView.
Abstract Alternate light sources (ALS) have been suggested to improve bruise visibility for medicolegal evaluations. Previous studies have recommended darkened conditions; however, this does not reflect real‐life autopsy settings, where multiple examinations are conducted simultaneously and turning off the lights is neither practical nor safe.

BirdNET: Automated Detection for Monitoring Critically Endangered Lemurs from the Maromizaha Forest

Integrative Zoology, EarlyView.
In this study, we evaluated the effectiveness of integrating PAM with BirdNET, a convolutional neural network originally developed for avian vocalization detection, to monitor two critically endangered lemurs, Indri indri and Varecia variegata, in Madagascar's Maromizaha rainforest.

Adenosine—A Regulator of Human Testicular Peritubular Cells

Andrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Bandpass filtering in barium titanate

Applied Optics, 1988
Real-time spatial filteirng is performed in BaTiO(3) using two different holographic geometries. In both geometries white light images of moderate intensity are used to filter selected portions of Fourier transform holograms written in the crystal. The result is a suppression of certain spatial frequencies in the reconstructed images.

Bandpass filtering with lowpass filters

Journal of the Franklin Institute, 1963
Abstract Lowpass filters may achieve the effects of bandpass filtering by heterodyning the bandpass wave to obtain the “in-phase” and “quadrature” components and filtering these with suitable lowpass filters. The impulse responses for the lowpass filters are determined in a simple way from the desired bandpass impulse response.

Ultrawideband Balanced Bandpass Filter

IEEE Microwave and Wireless Components Letters, 2011
A broadside-coupled structure is utilized to design balanced bandpass filter (BPF) with ultrawideband performance. The top and bottom layers of the structure contain tapered microstrip patches. Those patches are coupled via tapered slots in the ground plane, which is located at the middle layer.

Bandpass filtering in BaTiO3

Annual Meeting Optical Society of America, 1988
White light images are used to perform real-time spatial filtering in BaTiO3 in two different geometries. White light images act as spatial filters by erasing certain frequency components of photorefractive Fourier transform holograms. As a result, these frequency components are suppressed in the reconstructed holographic images.
