This paper presents the design and implementation of a low-cost, reliable three-wavelength (3-λ) illumination device intended for photoplethysmography imaging (PPGI) measurements. The proposed system employs high-power light-emitting diodes operating in the green (520 nm), red (625 nm), and near-infrared (855 nm) spectral regions, enabling non-contact cardiovascular monitoring with flexible spectral configuration. The illumination module integrates seven green LEDs, eleven red LEDs, and fifteen infrared LEDs, a distribution selected to compensate for wavelength-dependent camera sensitivity while providing sufficient radiant intensity and spatial uniformity at low power consumption and cost. Each wavelength channel is independently driven using dedicated single-channel linear LED drivers with pulse-width modulation control, allowing precise adjustment of illumination intensity. System operation is managed by a microcontroller-based control platform, which ensures accurate timing, synchronization, and stable operation required for PPGI applications. The compact and modular design supports straightforward integration with camera-based imaging systems, while optional wireless control enhances usability in laboratory environments. Overall, the proposed illumination device represents a robust and cost-effective solution for experimental and applied PPGI measurements in research-oriented non-contact biosensing systems.

Functional metagenomes, by combining new generation sequencing technologies, bio-informatics and genetic engineering, make it possible, even in non-cultivable microbial consortia, to identify enzymes with new technological characteristics, to technologize them and use them in various processes in order to obtain products with "added value". DNA sample of the first phase compost microflora (based on straw and chicken manure, 75 oC) from Jraber, Armenia (40°20'16.7"N 44°39'19.3"E) was sequenced by long-read nanopore technology using a MinION Mk1B apparatus with R9․4.1 flow cell. A total of 327,921 reads were analyzed with an average of 3269 bases per reads. 98 % Bacteria, 1% Eukaryota and 1% Archaea+Viruses were detected among obtained reads. Representatives of the Deinococcus-Thermus filum were in the lead - 55.75 %, followed by Proteobacteria - 10.44% and Firmicutes - 6.64%. In the genus level Thermus was in majority – 55.66 %, followed by Escherichia – 4.26 % and Pseudomonas – 2.04 %. And in species level Thermus thermophilus composed 49.32 %, followed by Thermus parvatiensis – 4.73 % and Escherichia coli – 4.24 %. The resulting metagenome contains the necessary number of genes to obtain recombinant cellulases, hemicellulases, and lignin-modifying enzymes for lignocellulose degradation.

This repository contains the data and analysis scripts supporting the manuscript entitled “Extreme floristic turnover between coastal fog oases and Andean shrublands: lichen diversity and community assembly in southern Peru”. The study documents lichen diversity and community differentiation across coastal fog oases and Andean shrublands in the Moquegua region, southern Peru. The repository includes the species abundance matrix at the sampling-unit level, the taxonomic checklist, processed community matrices used in the main analyses, station-level metadata, and R scripts for data preparation, alpha diversity, beta diversity partitioning, functional composition, diagnostic species analysis, and final figure assembly. Sampling was conducted across eight sectors representing two contrasting ecosystem types: three coastal fog oasis sectors (Tacahuay, Huacaluna, and Amoquinto) and five Andean shrubland sectors (Altarani, Alto Coscore, Calientes, Charaque, and Tala). The full sampling design comprised 40 stations and 200 sampling units. Because no lichen species were recorded in Amoquinto under the standardized sampling protocol, this sector was retained in richness and detection summaries but excluded from species-composition analyses requiring non-empty community matrices. This repository was prepared specifically for the current manuscript submission and contains the analytical inputs and scripts corresponding to the results reported in this version of the study.

Grapes are one of the most important crops in global agriculture, primarily used for wine, fresh fruit, and raisins. Nevertheless, grapevines are prone to various diseases that can significantly impact their yield and quality. Early detection and treatment of these diseases is essential. We introduce the "GVLiD: GrapeVine Leaf identification of the Diseases", which has 4 classes of 3,477 high-resolution images of grape leaves. The dataset covers the following common grapevine diseases: 1) Healthy, 2) Black rot, 3) Esca, and 4) Leaf blight. The dimensions of the images are 1080 × 1080. Images are in JPG format. Images having 120 DPI collected through a field visit and captured from different angles. Unlike existing datasets, GVLiD incorporates high-resolution field-acquired images with structured metadata, enabling real-world disease detection

Data from a quantitative correlational study yielded 198 valid responses. Parents rated 40 questionnaire items on a 5-point Likert scale regarding their involvement in managing senior secondary pre-class tasks for flipped mathematics instruction. Sampling details: 266 questionnaires distributed, 221 returned, 23 invalid responses excluded.

New studies in vision science indicate that visual art frequently deviates from the fundamental principles of physics and is only comprehensible within the context of human consciousness. An example is the Impossible Object, which is also known as an impossible figure or an undecidable figure, and is a kind of optical illusion. It comprises a two-dimensional form that is instantly and intuitively recognized as a projection of a three-dimensional object, but it cannot exist as a tangible reality. These figures often challenge our perception and highlight the complexities of visual interpretation. Artists and designers frequently utilize impossible objects to provoke thought and spark curiosity in their audiences. Oscar Reutersvärd, a Swedish artist, was among the first to create a multitude of impossibly complex artifacts intentionally. He has been referred to as “the father of impossible figures.” His work challenges perceptions of reality and invites viewers to explore the boundaries of visual representation. Through intricate designs and paradoxical structures, Reutersvärd’s art continues to inspire artists and mathematicians alike. The Swede conceived his impossible triangle while illustrating cubes in perspective. It must have been a time of revelation for him. A shape emerged before him that he could represent in two dimensions; however, it cannot exist in three dimensions. This paradox captivated his imagination, leading him to explore the boundaries of perception and reality. As he sketched, he pondered the implications of such illusions and how they challenged the viewer’s understanding of space and form. MIT researchers have created a novel tool, named Meschers, enabling users to generate intricate computer representations of mathematically impossible things. Meschers may ultimately contribute to the study of geometry and thermodynamics, as well as art and architecture. This innovative tool opens up new avenues for exploring concepts that challenge conventional understanding, allowing both scientists and artists to visualize and manipulate complex structures. As a result, Meschers is poised to inspire a new wave of creativity and innovation across various fields, encouraging interdisciplinary collaboration. By bridging gaps between mathematics, science, and the arts, it fosters a deeper appreciation for the beauty of abstract concepts and their practical applications. Psychologists and perception experts have extensively examined individuals’ impressions of impossible things. The physical setting of vision influences the personal experience of seeing an impossible thing.

The following data were collected using an ADCP (acoustic doppler current profiler) at coordinates 0.82881° N and 128.25178° E from August 29 to September 13, 2022. The dataset includes near-surface currents measured at a depth of 4.5 meters, along with tidal elevations derived from the ADCP’s built-in pressure sensors. The current data have been processed to separate tidal components from the residual currents using appropriate filtering techniques.
