Effective waterfowl management relies on the collection of relevant demographic data to inform land-management decisions; however, some types of data are difficult to obtain. For waterfowl, brood surveys are difficult to conduct because wetland habitats often obscure ducklings from being visually assessed. Here, we used Unoccupied Aerial Systems (UAS) to assess what wetland habitat characteristics influenced brood abundance in Suisun Marsh, California, USA. Using a thermal-imaging camera, we surveyed 17 wetland units that encompassed 332 ha of flooded area on the premises of seven waterfowl hunting clubs during the waterfowl breeding season. Additionally, using a combination of multi-spectral imagery collected from the UAS flights and LiDAR data from the previous year, we mapped habitat composition within each unit to relate to brood observation counts. From June 3–7, 2019, we identified 113 individual broods comprising 827 ducklings. We found a positive relationship between the number of broods observed and the proportion of the unit that was flooded. We also found a positive relationship between the number of broods observed and the area of effective habitat—a metric of flooded habitat within two times the 95th-percentile Euclidean distance that all broods were observed from any vegetated cover. Brood surveys using UAS could complement the traditional Breeding Population Survey and provide local managers with fine-scale and timely information about shifts in brood abundance in the region.
Developing a neuro-flexible mechanism of bankruptcy risk estimation based on conditional parameters
Authors: Sinkovskyi Artem , Shulakov Volodymyr 
Published: September 2024

The object of the study is the estimation of the risk of enterprise bankruptcy. The work is aimed at developing a new model for estimating the risk of enterprise bankruptcy. Estimating the risk of bankruptcy is critical to assessing a company’s financial health. It serves as a key indicator that enables management teams to proactively mitigate potential risks and develop strategies to strengthen the company’s financial position over time. It is possible to enhance our prior bankruptcy prediction model by eliminating the Neural Arithmetic Logic Unit (NALU) block and refining the fuzzifier block to assess if the new architecture can effectively simulate approximate arithmetic for discovering complex financial ratios and relationships. The new model uses our bespoke «neuro-flexible» mechanism that incorporates a fuzzifier block as its initial layer, transforming each financial parameter into a fuzzy representation without any NALU blocks down the line. This approach allows the model to process undefined or missing inputs, enhancing its robustness in varied financial scenarios. The fuzzified values are then processed through linear layers with Mish activation, known for superior generalization performance. Key improvements include optimal categorization of raw numbers through embedding vectors and significant acceleration in learning speed. Experiments conducted using PyTorch on an Apple M1 processor demonstrated a substantial average prediction performance of 72 %, indicating the efficacy of the proposed enhancements in bankruptcy estimation. Bankruptcy risk is important for assessing a company’s financial health. It helps management teams reduce risks and strengthen the company’s finances. By predicting bankruptcy risk, companies can take steps to avoid financial problems and stay in business.

Introduction: The amount of thoracic kyphosis and its mobility may be affected by gender in older adults. This study investigates gender differences in thoracic kyphosis and thoracic spine mobility in healthy older adults.
Materials and Methods: In this cross-sectional study, 36 participants among which 21 were female and 15 were male with an age range of 65-80 years participated. The amount of thoracic spine kyphosis was measured in a relaxed standing position and the position of maximum correction of thoracic kyphosis using a flexible ruler between the spinous processes of T12 and C7. The difference between the thoracic kyphosis of the relaxed state and the condition of the maximum correction is used to determine the degree of thoracic spine mobility. Finally, men and women were compared in terms of thoracic kyphosis and thoracic spine mobility. The student t-test was employed to compare kyphosis and spinal mobility between men and women, and the paired student t-test was used to compare kyphosis angle in a relaxed posture and maximum kyphosis correction status. Meanwhile, the Pearson test was utilized to evaluate the relationship between variables.
Results: Although there was no statistically significant difference in the mean thoracic kyphosis of relaxation (P=0.13) and maximal correction (P=0.18) status of healthy old men and women, there was a significant positive relationship between the rate of kyphosis angle and the amount of mobility of thoracic kyphosis (P=0.003; r=0.48).
Conclusion: There is no difference in the degree of kyphosis and thoracic spine mobility in older men and women. In addition, people with more thoracic kyphosis had more spinal mobility.

Introduction: Various balance exercises have been employed to enhance functional stability and balance in individuals who have undergone anterior cruciate ligament (ACL) reconstruction; however, no study has explored the use of dual-task balance exercises for these patients. This study compares the effects of dual motor task balance exercises and single-task exercises on the static balance indices of individuals with ACL reconstruction.
Materials and Methods: In a single-blind randomized controlled trial, 27 subjects who had undergone ACL reconstruction were randomly divided into two groups: Dual-task and single- task balance exercises. Both groups performed their exercises three days a week for one month. Static balance indicators were assessed at the beginning and end of the treatment.
Results: The results demonstrated that after the treatment, there was a statistically significant decrease in various center of pressure variables, including mean displacement in the anterior- posterior and medial-lateral directions, total path length, mean velocity of displacement, root mean square of displacement, and velocity. Furthermore, the knee injury and osteoarthritis outcome score significantly increased in both groups (P<0.05). However, when comparing the two groups, no significant difference was observed after the treatment (P>0.05).
Conclusion: Dual-task and single-task motor exercises improve static stability and knee function levels in patients who have undergone ACL reconstruction. Meanwhile, the effectiveness of these exercise types does not significantly differ from each other.

Abstract

Atomic-scale imaging and spectroscopy are essential for distinguishing hydrogen from deuterium, crucial in identifying structures and properties of organic materials with designed isotopic functionalities. However, conventional structural analysis techniques for materials containing both isotopes, likeneutron scattering, provide only averaged information across the beam area. In our study, we utilized vibrational spectroscopy with a monochromated transmission electron microscope, achievingdiscrete imaging of hydrogen and deuterium in organic polymers at single-nanometre resolution. This method's key advantage lies in its capability to distinguish between carbon-hydrogen (C–H) and carbon-deuterium (C–D) stretches by detecting slight differences in vibrational energy. The technique allowed for C–H/C–D mapping, which uncovered surface segregation of the deuterated polystyrene (dPS) component within a block copolymer film composed of dPS and poly(2-vinylpyridine). Moreover, it enabled the clear visualization of the spatial distribution of hydrogenated and deuterated polystyrene (hPS and dPS) on a molecular scale in a bulk block copolymer specimen containing both components.

Abstract

Sustainable agriculture highly relies on pollinators which affect the production and diversity of around 75% of foodcrops worldwide. However, the population and fitness of pollinators are showing sharp declining trends for years. Exposure to insecticides especially during crop pollination together with lacking effective management method has been reported as a dominant factor. Here, we have developed versatile and potent insecticide scavengers based on locust cell membrane and tannic acid (TA)-coated mesoporous silicon microparticles (MTSM) to prevent pollinators from a broad-spectrum insecticides including organophosphorus, pyrethroids, and neonicotinoids. Leveraging the π-π stacking with TA and specific binding by the acetylcholinesterases, nicotine receptors of acetylcholine, or voltage-gated sodium channels on locust cell membrane, MTSM presented enormously high removal efficiency of various insecticides while minimum nonspecific clearance of favorable enzymes mainly exsisting in gastrointestinal system of bees. Notably, MTSM exhibited over 12 h residency in gastrointestinal tract of bumblebees to facilitate insecticide scanvenging, and could be almost entirly excreted from bees within 48 h, causing no death of bees even at a high concentration of 50 mg/mL. In microcolonies of bumblebee fed with insecticide-contaminated impatien pollen patties, MTSM revealed dose-dependent detoxicification capacity towards organophosphorus and neonicotinoids insecticides. In sharp constrast to complete death of bumblebees fed with triazophos at a dose of 98 ng/bee within 5 days, the survival rate of bumblebees was significantly elevated to 75% and 90% by MTSM at doses of 1.0 and 20 mg/mL within 10 days, respectively. Overall, MTSM combining the merits of good safety, facile construction, and efficient and broad-spectrum detoxification presents versatile and potent scavengers to protect managed pollinators from multiclass insecticides.
