Neural Network Algorithm for Biometric Analysis of Human Retina Image

Clinical Evaluation of a New Spectral-Domain Optical Coherence Tomography-Based Biometer.

The VEMoS-AXL system is a new optical biometer based on spectral domain optical coherence tomography (SD-OCT) that has been tested in terms of intrasession repeatability and compared with a swept-source optical coherence tomography biometer (SS-OCT), which is recognized as the gold standard for the performance of an agreement analysis. A biometric analysis was performed three consecutive times in 120 healthy eyes of 120 patients aged between 18 and 40 years with the SD-OCT system, and afterwards, a single measurement was obtained with the SS-OCT system. Within-subject standard deviations were 0.004 mm, 4.394 µm, and 0.017 mm for axial length (AL), central corneal thickness (CCT), and anterior chamber depth (ACD) measures obtained with the SD-OCT biometer, respectively. The agreement between devices was good for AL (limits of agreement, LoA: -0.04 to 0.03 mm) and CCT (LoA: -4.36 to 14.38 µm), whereas differences between devices were clinically relevant for ACD (LoA: 0.03 to 0.21 mm). In conclusion, the VEMoS-AXL system provides consistent measures of anatomical parameters, being most of them interchangeable with those provided by the SS-OCT-based gold standard.

Biometric analysis of food products of hybrid hypoophthalmichthys (Hypophthalmichthys spp.) to determine their nutritional value and use in the food industry

This scientific work describes research, the purpose of which was to study the spectrum of nutrition and the composition of the food lump, as studies aimed at assessing specific weight (%) of essential nutrients (glycogen, proteins, and lipids) in particular organs and tissues of different size and mass groups of the hybrid of Silver carp and Bighead carp in ponds and reservoirs in different periods of the year. In 2018, and 2019, the juveniles of the hybrid of Silver carp and Bighead carp in ponds and reservoirs mainly consumed phytoplankton organisms (from 30 to 90% by mass), among which green, diatom, and euglena algae predominated by mass in the food group. Zooplankton occupied an insignificant place in fish nutrition (up to 5%), even though its quantity and biomass were sufficient in reservoirs. The hybrid of Silver carp and Bighead carp does not hurt zooplankton communities, so it can be included in the stocking volume of Silver carp. The feeding spectrum and rations of different groups of Silver carp and Bighead carp in ponds and reservoirs had a well-defined seasonal character related to the composition of feed objects. In all size and mass groups of the hybrid of silver and bighead carp from ponds and reservoirs in 2018, and 2019, mostly satisfactory values of general metabolism indicators were found – glycogen, proteins, and lipids in the liver, gills, and muscles of fish. The difference found in the availability of essential nutrients in the body of the studied fish indicates a change in the intensity and direction of their metabolic processes.

Biometric analysis hand parameters in young adults for prosthetic hand and ergonomic product applications.

This study aimed to evaluate the superficial anatomy, kinesiology, and functions of the hand to reveal its morphometry and apply the findings in various fields such as prosthetic hand and protective hand support product design. We examined 51 young adults (32 females, 19 males) aged between 18-30. Hand photographs were taken, and measurements were conducted using ImageJ software. Pearson correlation analysis was performed to determine the relationship between personal information and the parameters. The results of the measurements showed the average lengths of finger segments: thumb (49.5±5.5 mm), index finger (63.9±4.1 mm), middle finger (70.7±5.2 mm), ring finger (65.5±4.8 mm), and little finger (53.3±4.3 mm). Both females and males, the left index finger was measured longer than the right index finger. The right ring finger was found to be longer than the left in both sexes. Additionally, length differences between fingers in extended and maximally adducted positions were determined: thumb-index finger (56.1±6.2 mm), index-middle finger (10.7±4.1 mm), middle-ring finger (10.8±1.4 mm), and ring-little finger (25.6±2.7 mm). Other findings included the average radial natural angle (56.4°±10.5°), ulnar natural angle (23.4°±7.1°), radial deviation angle (65.2°±8.2°), ulnar deviation angle (51.2°±9.6°), and grasping/gripping angle (49.1°±5.8°). The average angles between fingers in maximum abduction positions were also measured: thumb-index finger (53.4°±6.5°), index-middle finger (17.2°±2.6°), middle-ring finger (14.3°±2.3°), and ring-little finger (32.1°±7.0°). The study examined the variability in the positioning of proximal interphalangeal joints during maximum metacarpophalangeal and proximal interphalangeal flexion, coinciding with maximum distal interphalangeal extension movements. The focal points of our observations were the asymmetrical and symmetrical arches formed by these joints. This study provides valuable hand parameters in young adults, which can be utilized in various applications such as prosthetic design, ergonomic product development, and hand-related research. The results highlight the significance of considering individual factors when assessing hand morphology and function.

Missmatch Industri Dan SMK: Fenomena SMK Penyumbang Angka Pengangguran Tinggi

Vocational High Schools (SMK - Sekolah Menengah Kejuruan) have become the largest contributor to unemployment figures, contrary to their intended purpose of preparing graduates for the workforce. This issue is attributed to a mismatch between the needs of the industry and the education provided by vocational schools. The aim of this research is to identify steps that should be taken to reduce the industry-school mismatch. The method employed involves biometric analysis using Vos Viewer, with data sourced from Google Scholar, including scientific articles in journals and in English. The results and findings of this research indicate that the mismatch is caused by a lack of synchronization between industrial advancements and the curriculum in vocational schools, students' lack of preparedness for the job market, and various supporting skills. This study suggests further investigation into industry-school mismatches based on specific fields of expertise in each vocational school. Consequently, in the future, vocational schools should no longer be the leading contributor to unemployment but rather contribute to the workforce in various fields within industries, aligning with the demands of the respective industries.

Research of thyroglobulin gene polymorphism in cows of Kostroma and black-and-white breeds of Kostroma region

Relevance. The genotype of the animal plays a significant role in realizing its productive potential, along with other factors affecting dairy productivity. Marker-oriented breeding (MAS) of cattle, which utilizes genetic markers associated with economically valuable traits, has gained popularity in the last two decades. One such marker is the thyroglobulin (TG) gene, which is involved in the production of a thyroid prohormone.Methods.The research was conducted on cows of Kostroma and black-and-white breeds at breeding farms in the Kostroma region. Genetic material was obtained from the tail vein of the cows using individual vacuum systems with an anticoagulant. The polymorphism of the TG gene (rs135751032) was determined using RT-PCR and detection by hybridization-fluorescence method. The results were processed using biometric analysis and calculation of population-genetic indicators.Results. In the populations of cows of the Kostroma and black-and-white breeds of the Kostroma region, the predominance of carriers of the CC genotype and the C allele of the thyroglobulin gene was established. At the same time, among cows of these breeds, there is a tendency to higher milk productivity in heterozygous animals. The nature of the associative relationship between TG genotypes and milk productivity indicators differed significantly for each individual herd. This indicates the need to study TG in combination with other DNA markers of milk productivity and metabolism. Statistically significant differences between cows of different TG genotypes were found only in full-aged animals, which perhaps indicates the prospects of using TG to determine the genetic potential of productive longevity of cows.

Methods: A bioinformatic protocol for rapid analysis of zebrafish embryo photo-motory responses (PMR) in neurotoxicity testing

Chemobehavioural phenotyping presents unique opportunities for analyzing neurotoxicants and discovering behavior-modifying neuroceuticals in small aquatic model organisms such as zebrafish (Danio rerio). A recently popularized approach in this field involves the utilization of zebrafish embryos for a photo-motor response (PMR) bioassay. The PMR bioassay entails stimulating zebrafish embryos between 24 and 36 h post fertilization (hpf) with a high-intensity light stimulus, inducing a transient increase in the frequency of photo-induced embryo body flexions. These flexions can be computationally analyzed to derive behavioral signatures, enabling the categorization of neuromodulating chemicals.Despite the significant advantages of the PMR bioassay, its widespread implementation is hindered by lack of well described and straightforward high-throughput bioinformatic analysis of behavioral data. In this methods article, we present an easily implementable bioinformatics protocol specifically designed for rapid behavioral analysis of large cohorts of zebrafish specimens in PMR bioassays. We also address common pitfalls encountered during PMR analysis, discuss its limitations, and propose future directions for developing next-generation biometric analysis techniques in chemobehavioural assays utilizing zebrafish embryos.

Efficacy of the DRL orthokeratology lens in slowing axial elongation in French children.

This study aims to assess and compare the impact of Orthokeratology Double Reservoir Lens (DRL) versus Single Vision Lenses (SVL) on axial elongation and anterior chamber biometric parameters in myopic children over a 6- and 12-month treatment period in France. A retrospective study involving 48 patients aged 7 to 17 years, who underwent either orthokeratology treatment or single-vision spectacle correction, was conducted. Changes in refractive error, axial length, and anterior chamber depth were examined. Twenty-five patients comprised the Orthokeratology (OK) group, while twenty-three were in the control group (single-vision spectacle group). Significant increases in mean axial length were observed over time in both the control (0.12 ± 0.13 mm and 0.20 ± 0.17 mm after 6 and 12 months, respectively; F (2,28.9) = 27.68, p < 0.001) and OK groups (0.02 ± 0.07 mm and 0.06 ± 0.13 mm after 6 and 12 months, respectively; F (2,29.1) = 5.30, p = 0.023). No statistically significant differences in axial length were found between male and female children (p > 0.620). Age-specific analysis revealed no significant axial elongation after 12 months in the 14-17 years group in the OK group. Anterior biometric data analysis at 6 and 12 months showed statistical significance only for the DRL group. Orthokeratology resulted in an 86 and 70% reduction in axial elongation after 6 and 12 months of lens wear, respectively, compared to the single-vision spectacles group. Myopia progression was more pronounced in younger children, underscoring the importance of initiating myopia control strategies at early ages.

Multimodal biometric fusion sentiment analysis of teachers and students based on classroom surveillance video streaming

Abstract In the education system, teachers and students as the main body of the classroom; their emotional state in the classroom school is an important indicator of the effectiveness of the classroom. This study first explores biometric recognition, based on the needs of the classroom curriculum and the classroom monitoring as a sensor, to propose a multimodal biometric fusion detection method based on the fusion of face and gait recognition. The PCA algorithm is used to optimize the face recognition as well as the occlusion situation in the classroom to improve gait recognition, and then the face and gait are fused based on the decision layer to achieve the detection and recognition of the identity situation of teachers and students. On this basis, an expression recognition model is established using the attention mechanism, and an emotion analysis system is designed for the classroom curriculum. According to the empirical evidence of multimodal biometric fusion sentiment analysis, the mAP accuracy of this paper’s fusion method is 100% in Euclidean distance, and the accuracy is higher than 99% in cosine distance, which is obviously better than other methods, and the accuracy of this paper’s fusion recognition is above 95% under any condition limitations. At the same time, the correct rate of recognition of emotions such as listening, appreciation, resistance, doubt, and inattention are all higher than 85%, and the five indexes of average absolute error, Pearson correlation coefficient, Accuarcy5, Accuarcy2, and F12 score of this paper’s sentiment analysis have achieved the best results comparing with other sentiment analysis models, which proves the generalization and validity of this paper’s sentiment analysis.

SUSTAINABLE FOOD PACKAGING IMPACT TO THE REDUCTION OF TRANSPORT COSTS

People dealt with many new issues related to sustainable development goals. Different decisions oriented to sustainable food packing would be very useful, if they could bring significant effect through the reduction of CO2 emission. The paper focuses on sustainable food packing and its effect on reduction of freight transportation costs. This topic has many research gaps and requires theoretical and practical investigations. Integration of sustainability into long term process has clear implications for the environment. Meherishi et al. (2019) highlight that the process of creating sustainable packaging guarantees the optimal use of materials and energy and is efficiently regenerated without wasting of natural resources. The impact of food packaging on transportation is clear and depends on a number of factors, which are shaped by the characteristics of the food packaging. In addition, among benefits of sustainable food packaging are such main functions as product safety and its identification. Modern complex solutions covering sustainable packing and transport costs reduction are important for increasing environmental sustainability. The study aims to analyze the impact of packaging on the reduction of transport costs. The aim was reached by performing sustainable food packaging and its impact on the reduction of transport costs theoretical justification and by conducting biometric analysis. The overview of the literature of sustainable food packaging and its impact on the supply chain was conducted, and it was found that the food packaging described different types of packaging and new packaging technologies which have an impact on the supply chain and are determined by some factors related to the characteristics of food packaging and the nature of the supply chain. Equally the overview of literature on the transport of food dynamics and the role of transport costs reduction on sustainability was also conducted. It was found that there is a need to develop new technologies and methods for food management and CO2 emissions for longer transport routes reduction. Either the research was conducted by biometric analysis for 2022-2023 to identify current trends, and it was found that the number of analyzed articles, included four clusters, which show that topics are oriented to delivery, flow, algorithms, structure, and role. The bibliometry analysis results show that product packing has links with transport and delivery and algorithms. The authors provided investigations under the topic as it requires knowledge to fill the existing gaps.

Automated Extraction of Textural Features From Segmented Sentinel-1ASynthetic Aperture Radar Satellite Image Using Grey Level Co-Occurrence Matrix

This paper focuses on the automated extraction of textural features from segmented Sentinel-1A Synthetic Aperture Radar (SAR) imagery, which was captured on 25th August 2017. Textural properties play a pivotal role in discerning regions of interest in satellite imagery, essential for precise classification in diverse applications, including remote sensing, medical image analysis, biometric analysis, and document image analysis. To achieve this, the Local Adaptive Threshold (LAT) technique was employed for segmenting the foreground and background areas of the pre-processed vertical transmit-vertical receive (VV) polarized Sentinel-1A SAR data. The approach relies on second-order statistics, specifically co-occurrence measures, which evaluate the relationships between pairs of pixels within their local neighbourhood’s in the input image. Four fundamental second-order statistical measures, namely correlation, energy, homogeneity, and contrast, were computed using the Grey Level Co-occurrence Matrix (GLCM). The GLCM was generated by quantizing the foreground region of the segmented grey-scale image into different levels, including 8, 16, and 64 grey levels, considering two inter-pixel distances, d=1 and d=2, and adopting an omni-directional orientation (θ = 00, 450, 900, 1350).The results underscore the effectiveness of the GLCM-based approach in computing second-order statistical texture measures from the segmented SAR image. Notably, the findings highlight that quantizing the image to Ng=8 with d=1 and considering omni-directional statistical measures (θ = 00, 450, 900, 1350) significantly enhances performance.

PROBLEMATIC INTERNET USE PADA REMAJA: ANALISIS BIBLIOMETRIK

Apart from providing various conveniences, excessive internet use can also have negative impacts, one of which is problematic internet use (PIU). This research aims to find out studies regarding problematic internet use in teenagers so that further research can be carried out. The research method used is a biometric analysis using VOSviewer on published articles indexed by Scopus from 2018 to 2023. The research results show that searching journals on the scopus.com site with the keyword "Problematic Internet Use" brings up 413 journals. After that, it was reduced based on four aspects, namely (1) scientific articles written in English, (2) literature in the form of scientific articles published in Scopus-indexed journals, (3) articles published in 2018-2023, and (4) open journals. access. After carrying out the exclusion process based on these limitations, 101 journals were included. Based on data on the development of Scopus-indexed journals regarding problematic internet use from 2018 to 2023, the highest development was in 2022 with 25 journals and the lowest was in 2019 with 10 journals. In author collaboration, there were 406 authors but only 17 authors collaborated and were members of five groups. This shows the lack of significance of collaboration between authors. Apart from that, several research variables have opportunities for further research, such as those related to PIU prevention, family relationships, and emotional regulation.

Annual dynamics of ammonium and nitrate nitrogen content by using capsulated carbamide in cassettes of one-year-old seedlings of Scots Pine (Pinus sylvestris)

Over the past decades of forestry development in Russia, the main trends have been identified, according to which P. sylvestris planting material can be effectively grown in a container method with a closed root system, considering the forest-seed area. The purpose of the study was to study the annual dynamics of ammonium and nitrate nitrogen in a soil with P. sylvestris with a closed root system using encapsulated urea with hydroquinone and mulch. The objectives of the study were based on the study of the effect of mineral fertilizers on the annual dynamics of ammonium and nitrate nitrogen and their effect on the growth of seedlings. The object of the study was the dynamics of the content of these nitrogen compounds in the soil. The study was carried out by methods of agrochemical, biometric and statistical analysis. Thus, the use of extended-form carbamide makes it possible to cover the need of plants for nitrogen nutrition throughout the growing season, having a significant impact on their growth in stem height. The use of encapsulated carbamide with hydroquinone, 0.5 cm pine mulch, potassium monophosphate and phosphorous flour allows the production of the best P. sylvestris seedlings with a maximum height of 188.82±15.41 mm per year due to constant saturation of the soil with available nitrogen, on which a change in the growth rate of seedlings is almost directly dependent (R = 0.99821-0.99988; Multiple R = 0.99643-0.99977; Adjusted R = 0.98928-0.99930; p &lt; 0.01525-0.05978). At the same time, ammonium nitrogen has the greatest effect on it (p &lt; 0.01633-0.05436).

Effect of nanoparticles on the ex-vitro performance of cryopreservation-derived plant material.

The integration of nanoparticles into plant cryopreservation protocols holds great promise for improving the survival rates and recovery potential of explants. This study aimed to verify the effect of nanoparticles on the ex-vitro performance of cryopreservation-derived plants. Lamprocapnos spectabilis (L.) Fukuhara (bleeding heart) 'Gold Heart' and 'Valentine' cultivars were used as the plant material. The encapsulation-vitrification cryopreservation protocol of shoot tips included the preculture, encapsulation, dehydration, storage in liquid nitrogen, rewarming, and recovery steps. Gold (AuNPs), silver (AgNPs), or zinc oxide (ZnONPs) nanoparticles were added at varying concentrations, either into the preculture medium or the protective bead matrix during encapsulation. After the in vitro recovery, the plants were transferred to the glasshouse and subjected to detailed biometrical, biochemical and cytogenetic analyses. Nanoparticles had no evident effect on the acclimatization efficiency (80-100% survival) and leaf number in L. spectabilis 'Gold Heart'. Nonetheless, shoots developed from alginate beads supplemented with 5 ppm AuNPs were twice as long as the control, while the leaves of plants grown on the preculture medium with ZnONPs contained significantly more chlorophyll and had higher Leaf Soil-Plant Analysis Development (SPAD) values. Moreover, several NPs treatments stimulated the development of leaves, including their surface area, length, and perimeter. Higher ZnONPs levels enhanced also the replication process, resulting in higher nuclear DNA content. As for L. spectabilis 'Valentine', alginate augmentation with 5 ppm AgNPs or 5 ppm ZnONPs stimulated the elongation of shoots. There was also a tendency suggesting a positive influence of 5 ppm AgNPs in the alginate bead matrix on foliar growth. The effect of nanoparticles on the content of flavonoids, anthocyanins, and stress markers in the plants varied depending on the treatment and cultivar, but also on the organ studied (leaf or stem). Overall, L. spectabilis 'Gold Heart' was more stress-tolerant and genetically stable than 'Valentine' judging by the activity of Photosystem II (PSII) and flow cytometric analyses, respectively. The complex effects of nanoparticles on survival, biometric parameters, physiological responses, and cytogenetic events underscore the intricate interplay between nanoparticles and plant systems. Nonetheless, our research confirmed the positive effect of nanoparticles on the ex-vitro growth and development of L. spectabilis plants after cryostorage.

Rhizobium rhizogenes rolC gene promotes leaf senescence and enhances osmotic stress resistance in Arabidopsis: the positive role of abscisic acid

AbstractThe root oncogenic loci (rol) C oncogene has been identified as a key player during the plant‐Rhizobium rhizogenes interaction and is considered to confer resistance to plant abiotic stresses, yet the underlying mechanisms remain largely elusive. In this study, Arabidopsis plants constitutively overexpressing rolC were produced. Biometric analysis showed that rolC induced diverse phenotypic modifications, including dwarfism, increased number of stem branches (1.3 times more than WT), weak root growth, early flowering (1.6 days earlier than WT) and premature leaf senescence. In addition, senescence stimulus (exogenous ethylene: 10 or 100 μL L−1) and 10% (w/v) polyethylene glycol 6000 (PEG) treatments demonstrated that rolC mediated leaf abscisic acid (ABA) enhancement in Arabidopsis, and this might be involved in rolC‐induced premature leaf senescence and resistance enhancement to osmotic stress. It is concluded that rolC‐induced premature leaf senescence may be involved in an abiotic stress escape mechanism in Arabidopsis, which is closely related to the increase of endogenous ABA levels. These findings provide new insights into the role of rolC in plant‐bacterial interaction and uncover the potential of biotechnological application associated with R. rhizogenes/rol genes in plant drought defense.

Addressing Conservation Needs: Genetic Diversity and Population Ecology of the Endemic Tree Spondias tuberosa Arruda.

Spondias tuberosa Arruda (Anacardiaceae), popularly known as umbuzeiro or imbuzeiro, is a fruit tree native to the semiarid region of Brazil. The extractive harvesting of its fruits contributes significantly to the economy, generating an annual revenue of approximately $4,2 million. The present study aimed to assess the spatial pattern, allometric variations, fruit measurements, and genetic diversity of trees within a remaining forest of the Caatinga biome, with a focus on intrapopulation analysis. We used intersimple repeated sequence markers and the second-order function density of neighbours to determine the genetic and spatial structure. The density of neighbours was highest within a 10-meter radius. Biometric analyses revealed average fruit lengths of 31.12 mm (±0.22), diameters of 28.68 mm (±0.25), and fresh masses of 15.56 g (±0.33). Diaspores exhibited an average length, diameter, and thickness of 19.27 mm, 13.95 mm, and 11.14 mm, respectively, with a fresh mass of 2.28 g. Notably, the fresh mass demonstrated the highest coefficient of variation. Ten molecular markers were selected, generating 103 highly polymorphic loci (99.03%) with an average informative content of 0.45. Nei's diversity index (0.37) and Shannon's index (0.55) indicated moderate genetic diversity. Furthermore, Bayesian analysis revealed a population structure with two distinct genetic groups. The Infinite Allele and Mutation Step Models suggested a significant historical decline in population size, indicative of a genetic bottleneck. As a result, proactive in situ conservation strategies, including establishing protected natural areas, become essential, considering the socioeconomic significance of the species. Additionally, it is recommended to establish germplasm banks for ex situ conservation and the development of managed cultivation initiatives to reduce the pressure on native populations of S. tuberosa caused by extraction.

Biometric Analysis of Fish Remains from Palaeolake Boltysh (Ukraine)

The results of the study of the meristic and morphometric characters of complete and fragmentary skeletons of Notogoneus gracilis (Gonorynchidae) and Boltyshia brevicauda (Umbridae) recovered from Paleocene–Eocene lacustrine deposits of the Boltysh impact structure are presented in the paper. Some of the specimens previously assigned to Thaumaturus avitus were reidentified as Boltyshia brevicauda. The meristic characters of the specimens considered are stable in both species and refer to those in the respective type series. A previously unknown caudal fin formula (I 6–6 I) is observed in several specimens of Boltyshia brevicauda. The latter species is characterised by more variable meristic characters compared to Notogoneus gracilis.

New variety of white lupine Monica (Lupinus albus L.)

Characterization of promising white lupine hybrid lines (LN5 and LN1-1) and their parental forms (Lucky801 and PI533704) was done. Biometric analysis of each variety and line was performed according to main quantitative traits and phenological stages and periods. A new variety of white lupine Monica (from line LN5) was created with a direction of use for seeds. It was obtained through repeated individual selection from the cross Lucky801 ? PI533704. The variety belongs to the medium-ripening group with a duration of the vegetation period of 129 days. It has genetically completed growth. The height of the plant was 87 cm. The variety has high lodging resistance and good adaptability to abiotic conditions. The first pods were formed at 40 cm. The pods of the plant are formed on the main stem and on shortened lateral branches of the first and second order. About 28 uncrackable pods formed on one plant. The inflorescence is medium-sized, blue-white, the seeds are white, medium-sized. The number of seeds in one plant is on average 114. The protein content of the grain is 33%. The variety is distinguished by high potential seed productivity (the mass of seeds per plant 37 g). The mass of 1000 seeds is 339 g. The average yield of grain (3150 kg/ha) in the competition variety trials exceeds the average yield of the parental forms (2940 kg/ha). By decision of the Expert Commission at the Executive Agency for Variety Testing, Field Inspection and Seed Control, Bulgaria (appointed by order RD-10-1/14.01.2022) and by order No. RD-12-1 of the Minister of Agriculture of the Republic of Bulgaria dated 02.03.2022, the Monica variety was recognized as a new and original.
