CENOZOIC (PRE-PLIOCENE) PALEOENVIRONMENTAL TRENDS BASED ON PALYNOMORPHS FROM THE COLORADO BASIN, ARGENTINA

Abstract. Based on palynological studies, paleoclimatic trends were inferred for the Paleocene-Miocene of the marginal part of the Colorado Basin, Argentina. The data show warm and humid conditions during the Late Danian (Paleocene), a decline of temperature and humidity from the ? Mid Eocene to the Oligocene. Warm, humid conditions at the end of the Oligocene and Early Miocene were recorded; dry-temperate periods alternated with warmer humid ones during the Mid and Late Miocene. Temperature and humidity decreases coincide with sea level drops at Eocene/Oligocene, Early/Late Oligocene and Miocene/Oligocene boundaries. These paleoclimatic interpretations are compatible with those derived from calcareous microfossils of Colorado Basin, fossil plants from South America and global paleoclimatic changes inferred by other authors.

FLUCTUACIONES PALEOAMBIENTALES DEL CENOZOICO (PRE-PLlOCENO) EN BASE A PALlNOMORPHS EN LA CUENCA DEL COLORADO, ARGENTINA. A partir de estudios palinologicos realizados en el sector marginal de la Cuenca del Colorado, se determinaron las tendencias paleoclimaticas durante el lapso Paleoceno- Mioceno. Para el Daniano tardio (Paleoceno) fueron inferidas condiciones calidas y humedas; para el Eoceno medio, templado-calidas y humedas; posterior disminucion de la temperatura y humedad hasta el Oligoceno temprano; un mejoramiento climatico para el Oligoceno tardio y Mioceno temprano; alternancia de periodos humedos y calidos con episodios relativamente mas secos y frios, durante el Mioceno medio y tardio. Las principales inflexiones en las tendencias de temperaturas reconocidas presentan una notable correspondencia con los limites estratigraficos convencionales. Los limites Eoceno/Oligoceno, Oligoceno inferior/Oligoceno superior y Mioceno/Plioceno coinciden con disminuciones de temperatura y humedad relacionadas con caidas relativas del nivel del mar. Las tendencias paleoclimaticas propuestas en este trabajo son compatibles con la informacion disponible acerca de microfosiles calcareos de la Cuenca del Colorado, tafofloras de America del Sur y con las fluctuaciones paleoclimaticas de caracter global.

Modeling Multimodal Uncertainties via Probability Distribution Encoders Included Vision-Language Models

In the field of multimodal understanding and generation, tackling inherent uncertainties is essential for mitigating ambiguous interpretations across multiple targets. We introduce the Probability Distribution Encoder (PDE), a versatile, plug-and-play module that utilizes sequence-level and feature-level interactions to model these uncertainties as probabilistic distributions. Furthermore, we demonstrate its adaptability by seamlessly integrating PDE into established frameworks. Compared to previous methods, our probabilistic approach substantially enriches multimodal semantic understanding. In addition to specific tasks, the unlabeled data contains rich prior knowledge, especially multimodal uncertainties. However, current pre-training methods are designed based on point representations, which hinders the effective functioning of our distribution representations. Therefore, we incorporate this uncertainty modeling into three new pre-training strategies: Distribution-based Vision-Language Contrastive Learning (D-VLC), Distribution-based Masked Language Modeling (D-MLM), and Distribution-based Image-Text Matching (D-ITM). Empirical experiments show that our models achieve State-of-the-Art (SOTA) results in a range of downstream tasks, including image-text retrieval, visual question answering, visual reasoning, visual entailment and video captioning. Furthermore, the qualitative results reveal several superior properties conferred by our methods, such as improved semantic expressiveness over point representations, and the ability to generate diverse yet accurate predictions.

Optimization of Gate-Head-Top/Bottom Lengths of AlGaN/GaN High-Electron-Mobility Transistors with a Gate-Recessed Structure for High-Power Operations: A Simulation Study

In this study, we propose an optimized AlGaN/GaN high-electron-mobility transistor (HEMT) with a considerably improved breakdown voltage. First, we matched the simulated data obtained from a basic T-gate HEMT with the measured data obtained from the fabricated device to ensure the reliability of the simulation. Thereafter, to improve the breakdown voltage, we suggested applying a gate-head extended structure. The gate-head-top and gate-head-bottom lengths of the basic T-gate HEMT were symmetrically extended by 0.2 μm steps up to 1.0 μm. The breakdown voltage of the 1.0 μm extended structure was 52% higher than that of the basic T-gate HEMT. However, the cutoff frequency (fT) and maximum frequency (fmax) degraded. To minimize the degradation of fT and fmax, we additionally introduced a gate-recessed structure to the 1.0 μm gate-head extended HEMT. The thickness of the 25 nm AlGaN barrier layer was thinned down to 13 nm in 3 nm steps, and the highest fT and fmax were obtained at a 6 nm recessed structure. The fT and fmax of the gate-recessed structure improved by 9% and 28%, respectively, with respect to those of the non-gate-recessed structure, and further improvement of the breakdown voltage by 35% was observed. Consequently, considering the trade-off relationship between the DC and RF characteristics, the 1.0 μm gate-head extended HEMT with the 6 nm gate-recessed structure was found to be the optimized AlGaN/GaN HEMT for high-power operations.

ABREVIATURAS E SIGLAS

The development of increasingly smaller devices with greater processing power represents undeniable technological advancement in current times. Such a movement points towards facilitated and widespread access to tools, components, and items specially designed for independent and creative development, at a high level of customization. Analytical chemistry finds great value in such advances by instituting the Internet of Analytical Things (IoAT). Given the variety of available options, studying each component, its limitations, and functionalities is necessary. The objective of this work was to evaluate light sensors for applications in low-cost colorimetric devices; thus, different photodiodes and a photoresistor were evaluated, highlighting their spectral ranges of best applicability. Some analytes of environmental interest were assessed, and the obtained figures of merit were compared to those obtained by UV-vis spectrophotometry. Using a portable photometer, a procedure for sulfide determination in samples obtained from water treatment stations in the Triângulo Mineiro region was applied, and the analytical characteristics obtained, such as linear range: 0.26 to 3,00 mg/L; Detection limit of 0.09 mg/L, and coefficient of variation of 4.77 for mid-point measures, considered comparable to those obtained by the official method. The developed system has 18 hours of battery autonomy, a microcontroller with an integrated screen and buttons for user operation, a LED (635 nm), and an LTR-329 sensor for absorbance measurements. Another system tested for colorimetric determinations consists of implementing the sensor to replace the detector of the traditional spectrophotometer. The applicability was demonstrated in urea determinations in liquid reducing agent samples, with the system achieving a CV = 3.34 and DL of 0,06% (w/v) reaching statistically equivalent determinations to the reference spectrophotometric method with 95% confidence in concentrations with linear responses between 0,2 and 3,0%.
Research on the Link Between Economic Development Variables and the Rate of Access to Drinking Water in Rural Senegal Using Machine Learning

: After pre-processing a set of data collected from Senegalese state structures, official United Nations (UN), and world bank sites and after replacing missing values by interpolation using the mean between two values, we study the effect of macroeconomic development variables on the rate of access to drinking water in rural Senegal. To do this, we use Machine Learning (ML) techniques such as Linear Regression (LR), Decision Tree (DT), and Random Forest (RF) to identify a hidden correlation between the rate of access to drinking water and other variables. Based on the collected data, LR provides the best predictive accuracy, best RMSE (0.001), best MAE (0.011), and best R2 (96.9%) and help public development net received (ODA_NR_FBC) appears to be the most influential variable, predicting the rate of access to drinking water with greater precision than the other variables. This innovative approach can help us to better understand the factors influencing access to drinking water and to propose effective solutions.

Effect of Agricultural Cultivation on Soil Organic Carbon in China

Based on the data from the National Second Soil Survey,this paper analyzed the variation of topsoil organic carbon(SOC) content in cropland and non-cropland,and the difference of SOC content in cropland and non-cropland,paddy fields and upland field among 6 regions.At the same time,the change of topsoil SOC storage led by cultivation was estimated based on the data of SOC content in non-cropland and cropland area.The results indicated that the variation of SOC content in cropland was less than that in non-cropland,and that in paddy field was less than in upland field;secondly,the SOC content in cropland was less than that in non-cropland which decreased 51.5% in average,but that in paddy field was more than in upland field;thirdly,the loss of SOC pool led by the agriculture cultivation was 4.3 Pg,which including the decreasing of paddy field and upland field was 0.67 and 3.63 Pg respectively.At last,this paper analyzed the spatial distribution of the SOC pool loss,and discussed the reason of the most decreasing degree of SOC storage in Northeast and Northern China,which was the much cultivation of soil like black soil,chernozems,and dark brown soil in grassland and wetland,and the irrational agricultural field management.
Modeliranje trošenja medicinskog svrdla

Medicinska svrdla koristena u ortopediji i traumatologiji podložna su intenzivnom trosenju ostrica uslijed razlicitih mehanickih, kemijskih i toplinskih utjecaja koji se javljaju u postupku busenja kosti i sterilizacije. Porastom istrosenosti svrdla povecava se trenje između alata i obrađivane kosti, sto posljedicno rezultira porastom sila i temperature u zoni busenja. Porast sila rezanja može uzrokovati lom ostrice ili cijelog svrdla. Time nastaju mehanicka ostecenja kosti, a otežano je i vađenje dijelova svrdla sto može uzrokovati dodatnu traumu okolnog tkiva. S druge strane, porast temperature utjece na biokemijske procese u kostanom tkivu i može izazvati strukturna i funkcionalna ostecenja s ozbiljnim i ireverzibilnim posljedicama na biomehanicke karakteristike kosti u podrucju zahvata. Stoga je u ovom istraživanju razvijen model trosenja medicinskog svrdla s mogucnoscu kvalitetne kvantifikacije stupnja istrosenosti. Model je verificiran eksperimentalno prikupljenim podacima iz vise razlicitih senzora, primjenom odgovarajuceg ispitnog postava. Rezultati ukazuju da se postavljeni model može koristiti primarno u procjeni istrosenosti svrdla, a posredno i u određivanju temperature busenja i to u stvarnom vremenu za vrijeme obrade. Navedene karakteristike modela su od iznimnog znacaja za razvoj novih, potpuno autonomnih i adaptivnih mehatronickih sustava za medicinsko busenje.
Early Achilles Enthesis Involvement in a Murine Model of Spondyloarthropathy: Morphological Imaging with Ultrashort Echo-Time Sequences and Ultrasmall Superparamagnetic Iron Oxide (USPIO) Particle Evaluation in Macrophagic Detection

Purpose To confirm the interest of 3-dimensional ultrashort echo-time (3D-UTE) sequences to assess morphologic aspects in normal and pathological Achilles entheses in a rat model of spondyloarthropathy (SpA) with histological correlations, in comparison with conventional RARE T2 Fat-Sat sequences, and, furthermore, to evaluate the feasibility of a 3D multiecho UTE sequence performed before and after the intravenous injection of ultrasmall superparamagnetic iron oxide (USPIO) particles to assess macrophagic involvement in the Achilles enthesis in the same rat model of SpA. Materials and Methods Fourteen rats underwent in vivo MRI of the ankle at 4.7 T, including a 3D RARE T2 Fat-Sat sequence and a 3D ultrashort echo-time (UTE) sequence for morphologic assessment at baseline and day 3 after induction of an SpA model, leading to Achilles enthesopathy in the left paw (right paw serving as a control). A 3D multiecho UTE sequence was also performed at day 3 before and then 24 (4 rats) and 48 (2 rats) hours after intravenous injection of USPIO. Visual analysis and signal intensity measurements of all images were performed at different locations of the Achilles enthesis and preinsertional area. Visual analysis and T2∗ measurements were performed before and after USPIO injection, on the 3D multiecho UTE sequence in the same locations. Normal and pathological values were compared by Wilcoxon signed-rank tests. MR findings were compared against histological data. Results 3D-UTE sequences enabled morphologic identification of the anterior fibrocartilage and posterior collagenic areas of the Achilles enthesis. Visual analysis and signal intensity measurements distinguished SpA-affected entheses from healthy ones at day 3 (P=0.02). After administration of USPIO, no differences in signals were detected. Similarly, both visual analysis and signal T2∗ measurements in the enthesis were unable to distinguish the SpA-affected tendons from healthy ones (P=0.914). Neither the normal anatomy of the enthesis nor its pathological pattern could be distinguished using the standard RARE sequence. Histology confirmed the absence of USPIO in Achilles entheses, despite marked signs of inflammation. Conclusion Unlike conventional RARE T2 Fat-Sat sequences, 3D-UTE sequences enable morphologic assessment of normal enthesis anatomy and early detection of abnormalities in pathological conditions. However, 3D multiecho UTE sequences combined with USPIO injections with T2∗ measurements were unable to detect macrophagic involvement in these pathological conditions.
Unlocking eco-industry: green knowledge and good manufacturing practice fish scale waste utilization

Scales such as fish waste are considered worthless, even though they can be used as raw materials for collagen-making. This fish waste management process also contributes to reducing the problem of environmental pollution due to the disposal of fish waste that is not managed correctly. This study aims to determine the relationship between green knowledge upskilling (GKU) of employees, good manufacturing practice (GMP), and eco-performance (EP). The research site was determined by conducting a census of the 35 personnel at PT Marine Biogel Indonesia in Boyolali. The research model uses structural equations (SEM), and the analysis method uses partial least squares. The results show that GKU has a positive and significant effect on GMP. Second, GKU has a positive and significant effect on EP. Third, GMP has a positive and significant effect on EP. Finally, GKU positively and significantly affects EP mediated by GMP. Implementing eco-friendly production practices can increase the utilization of fishing industry waste on a large scale.
One decade of temperature change at the North Pole and South Pole using ANN backpropagation algorithm

Global warming is an event in which the average temperature of the atmosphere, ocean and land rises. Changes in atmospheric temperature cause changes in the physical conditions of the atmosphere to become unstable, causing anomalies in weather parameters that cause climate change. In the last decade there have been temperature changes in the North Pole (Greenland) and the South Pole (Antarctica). The impacts caused by temperature changes are melting ice sheets, rising sea levels, extinction of species in large numbers, people living on the coast are threatened by tidal floods, while small islands can sink. To anticipate temperature changes, a model is needed that can forecast air or temperature conditions using Artificial Neural Network with Backpropagation method using Matlab software media. Data obtained from Data Access Viewer of NASA. After training and testing the data, the average value of the prediction results for the south polar region (Antarctica) is -47.910C with a Mean Square Error (MSE) value of 0.0015. Meanwhile, for the North Pole region (Greenland), the average value of the prediction results is -22.410C with an MSE value of 0.0069. By looking at the average value of the prediction results, it can be concluded that the temperature change for the South Pole region (Antarctica) is higher than the temperature change for the North Pole region (Greenland).
A computational study photophysical properties of a series phenothiazine-linked-BODIPY as D-D-π-a photosensitizer unit for photo-induced hydrogen production from water

Phenothiazine-derivatives are designed as sensitizers which covalently-linked with BODIPY for application in a system of dye-sensitized photoelectrochemical cells (DSPECs). A series of phenothiazine-linked-BODIPY as D-D-π-A chromophore have been investigated by a computational approach for studying the capability of the photosensitizers for application in photoinduced water splitting hydrogen production in DSPECs. The geometries of sensitizers at the ground state and excited state were optimized by the CAM-B3LYP/6-31G (d,p) level method. The theoretical study has been done in order to investigate the photophysical properties such as absorption profile, HOMO-LUMO energy and surface plots of the photosensitizer. The result of calculation for HOMO-LUMO energy level of each dyes showed that the LUMO energy are ranging more than -2.8 - (-2.86) eV which is higher than -4.0 eV of conduction band of TiO2 as semiconductor in DSPEC, meaning that all these dyes could be used as photosensitizers in DSPECs. In addition, the oscillator strength data of each dyes showed the dyes have absorption profile in visible region, meaning the dyes could harvest higher intensity of sunlight to induce water splitting reaction to produce hydrogen.
A historical evaluation of the disease avoidance theory of xenophobia

Historical psychology is emerging as a multidisciplinary field for studying psychological phenomena in a historical context. Historical records can also serve as testbeds for psychological theories, particularly the evolutionary ones. In Study 1 we aimed to gather evidence to evaluate the disease avoidance theory of xenophobia by analyzing the narratives of European explorers from the15th and 16th centuries. Contrary to the theory’s expectations, the narratives revealed numerous instances of close physical contact between the explorers and the native populations. Furthermore, rather than using disgust-laden words, the explorers portrayed the natives in a positive light. In Study 2, we employed a word embedding algorithm to explore whether native group names and their unfamiliar appearance were associated with disgust-laden words in the 19th century travel literature. The results indicated that while native group names showed such associations, their appearance did not. Finally, through network analysis, we demonstrated that embedded words such as “savages” mediated the perception of native groups as potential disease-threat. The findings highlight the significance of cultural factors that evolve over time, rather than cognitive adaptations believed to have evolved prior to the emergence of human culture, in explaining xenophobia.
Microglial process dynamics depend on astrocyte and synaptic activity

ABSTRACT Microglial processes survey the brain parenchyma, but it is unknown whether this process is influenced by the cell activity of nearby microglia under physiological conditions. Herein, we showed that microglial process dynamics differ when facilitated by astrocytic activity and pre-synaptic activity. The results revealed distinct microglial process dynamics associated with the activity of other brain cells.
Pediatric retinal vascular disorders: From translational sciences to clinical practice

Pediatric retinal vascular diseases are a spectrum with overlapping phenotypes and related genes. Retinal vascular development is biphasic. Vasculogenesis is responsible for the formation of primordial vessels leading to the four major arcades in the posterior retina. Angiogenesis, which is vascular endothelial growth factor dependent, is responsible for the formation of new vessels through budding from existing vessels, forming the peripheral vessels, increasing the capillary density of the central retina, and forming the superficial and deep capillary plexus. This process is controlled by WNT signaling, which is important for cell proliferation, division, and migration. Disorders of WNT signaling, such as familial exudative vitreoretinopathy (FEVR), have overlapping clinical findings. Conversely, pathogenic variants in some of the FEVR-related genes are reported in conditions such as retinopathy of prematurity (ROP), persistent fetal vasculature, and Coats disease. The various overlapping features and underlying genetic basis in the pathogenesis of pediatric retinal vascular developmental diseases suggest that genetic variants may provide a framework or a background for these conditions, upon which further insults can affect the development at any phase (such as prematurity and oxygenation in ROP), influencing and determining the final phenotype.
