We report a multi parameters cardio-pulmonary (CP) monitoring system with features of low power consumptions (30mA,3.3V), miniaturization (size 25 cm), and wireless data communications (Frequency 96 MHz) for wearable applications in e-Health. Its target application is forthe evaluation of fitness of CP during exercises. We use aminiature bi-directional hot-wire sensor for respiratory function,an optical sensor for saturated blood oxygen level or plethsymograph, and two surface electrodes for single lead electrocardiograph. The fitness indexes include blood oxygen level, ECG, and respiratory functions, which will be used for the quantitative evaluation of the level of physical activity.

CBGTPy: An extensible cortico-basal ganglia-thalamic framework for modeling biological decision making.
PLoS One
January 2025
Departament de Ciències Matemàtiques i Informàtica, Universitat de les Illes Balears, Palma, Spain.
Here we introduce CBGTPy, a virtual environment for designing and testing goal-directed agents with internal dynamics that are modeled on the cortico-basal-ganglia-thalamic (CBGT) pathways in the mammalian brain. CBGTPy enables researchers to investigate the internal dynamics of the CBGT system during a variety of tasks, allowing for the formation of testable predictions about animal behavior and neural activity. The framework has been designed around the principle of flexibility, such that many experimental parameters in a decision making paradigm can be easily defined and modified.

Department of Public and Occupational Health, Amsterdam UMC, Location AMC, Amsterdam, the Netherlands.
Objective: While chest pain is a common symptom, its prevalence among women and men across ethnic groups is unknown. Moreover, how chest pain is associated with general practitioner (GP) and cardiologist visits in women and men across ethnic groups, remains to be determined.
Design: We used baseline data on 12423 women and 9071 men from the multi-ethnic HELIUS cohort (Amsterdam, the Netherlands; 2011-2015).
Effects of multi-enzymes supplementation to wheat and soybean meal-based feeds on growth performance, digestibility and carcass characteristics of quails.

Japanese quail () is a popular experimental animal model in scientific research. The present study investigated the effects of dietary multiple enzyme supplementation on growth performance, carcass characteristics, nutrient digestibility and small intestinal histomorphology in quails fed diets based on wheat and soya bean meal. A total number of 192 1-day-old quails were assigned to three treatments with 16 replicates in each and four quails replicate for 38 days.

The LLaMA family, a collection of foundation language models ranging from 7B to 65B parameters, has become one of the most powerful open-source large language models (LLMs) and the popular LLM backbone of multi-modal large language models (MLLMs), widely used in computer vision and natural language understanding tasks. In particular, LLaMA3 models have recently been released and have achieved impressive performance in various domains with super-large scale pre-training on over 15T tokens of data. Given the wide application of low-bit quantization for LLMs in resource-constrained scenarios, we explore LLaMA3's capabilities when quantized to low bit-width.

High birefringence nematic liquid crystals are particularly demanded for adaptive optics applications in the infrared spectrum because it enable a thinner cell gap for achieving fast response time and improved diffraction efficiency. The emerging ferroelectric nematic liquid crystals have attracted widespread interest in soft matter due to their unique combination of ferroelectricity and fluidity. However, the birefringence, which is one of the most important optical parameters in electro-optic devices, is not large enough (<0.
