Research on the Palu earthquake in the period of August to October 2018 has been carried out in the Palu Koro Fault (PKF) zone with a hypocenter of 5-20 km. This study aims to determine the fractal dimensions of these earthquakes based on the relationship between logarithmic frequency and earthquake magnitude correlation introduced by Gutenberg-Richter. Statistical correlation between logarithmic frequency and earthquake magnitude was calculated using the inversion approach. Based on the calculation results obtained fractal dimension value of 1.0378, which describes the seismicity pattern at a depth of 5-20 km. It indicates that the earthquakes triggered by the movement in rupture segments which seen as points along the PKF zone.

The existence of aquatic plants has a significant influence on the biota living at wellspring. The osmotic pressure is significant research to understand the adaptation of the environment changing to organism physiology. This research aims to know the Osmotic Work Rate by comparing osmolarity water value to aquatic plant plasma. The research method is the descriptive analysis of laboratory test results. The water sample was taken from the seven locations of the wellspring. Osmotic work rate is taken from comparing the plasma osmolarity value of the aquatic plant to water Osmolarity. Osmotic work rate zero means osmoregulation patterns isosmotic. The osmotic work rate greater than zero implies osmoregulation patterns hyperosmotic regulatory and osmoregulation patterns hypo-osmotic regulatory if the Osmotic work rate is less than zero. The patterns are used from the seven locations of good springs are the same, osmoregulation patterns of Hyperosmotic regulatory to the environment because the plasma osmolarity of water plants is more significant than water osmolarity.

The Choushui River groundwater basin (CRGB) in Yunlin County, Taiwan, is a significant groundwater source for the western part of the region. However, increasing groundwater demand and human activities have triggered a potential crisis due to overexploitation. Therefore, groundwater potential zone (GWPZ) maps are crucial for mapping groundwater resources and water resource management. This study employs the normalized index–overlay method and fuzzy extended analytical hierarchy process (FE-AHP) to map GWPZs cost-effectively. The methodology objectively incorporates weightings from various thematic layers by normalizing and correlating parameters with observed groundwater availability (GA). Site-specific observations, including aquifer thickness, depth to the groundwater level, and porosity, inform GA calculations. Seven comprehensive layers derived from remote sensing (RS) data are processed to obtain weightings and ratings for the groundwater potential index (GWPI) in the CRGB. Selected parameters are categorized into hydrological processes, human interventions, geological, and surface profiles. Hydrological processes include precipitation, modified normalized difference water index (MNDWI), and drainage density. Human interventions consist of the enhanced vegetation index (EVI) and normalized difference building index (NDBI). Surface profiles encompass the terrain ruggedness index (TRI) and slope, enhancing the study’s multi-criteria approach. The observed GA validates the GWPZ accuracy, classifying zones into five categories. According to the GWPI of FE-AHP, about 59.56% of the CRGB area can be categorized as "moderate" to "very good" potential groundwater recharge zones. Pearson’s correlation coefficient between GWPI and GA, based on FE-AHP, outperforms the conventional AHP. This RS-based approach efficiently evaluates GA in aquifers with limited wells, highlighting crucial zones in CRGB’s proximal-fan and southeastern mid-fan for informed groundwater management

Neurotrophic receptor tyrosine kinase 3 (NTRK3) has pleiotropic functions: it acts not only as an oncogene in breast and gastric cancers but also as a dependence receptor in tumor suppressor genes in colon cancer and neuroblastomas. However, the role of NTRK3 in upper tract urothelial carcinoma (UTUC) is not well documented. This study investigated the association between NTRK3 expression and outcomes in UTUC patients and validated the results in tests on UTUC cell lines. A total of 118 UTUC cancer tissue samples were examined to evaluate the expression of NTRK3. Survival curves were generated using Kaplan–Meier estimates, and Cox regression models were used for investigating survival outcomes. Higher NTRK3 expression was correlated with worse progression-free survival, cancer-specific survival, and overall survival. Moreover, the results of an Ingenuity Pathway Analysis suggested that NTRK3 may interact with the PI3K-AKT-mTOR signaling pathway to promote cancer. NTRK3 downregulation in BFTC909 cells through shRNA reduced cellular migration, invasion, and activity in the AKT-mTOR pathway. Furthermore, the overexpression of NTRK3 in UM-UC-14 cells promoted AKT-mTOR pathway activity, cellular migration, and cell invasion. From these observations, we concluded that NTRK3 may contribute to aggressive behaviors in UTUC by facilitating cell migration and invasion through its interaction with the AKT-mTOR pathway and the expression of NTRK3 is a potential predictor of clinical outcomes in cases of UTUC. © 2024 The Authors.

Star formation rate (SFR) is a fundamental parameter for describing galaxies and inferring their evolutionary course. H II regions yield the best measure of instantaneous SFR in galaxies, although the derived SFR can have large uncertainties depending on tracers and assumptions. We present an SFR calibration for the entire molecular gas disk of the nearby Seyfert galaxy NGC 1068, based on our new high-sensitivity ALMA 100 GHz continuum data at 55 pc (= 0′′ . 8) resolution in combination with the HST Paα line data. In this calibration, we account for the spatial variations of dust extinction, electron temperature of H II regions, AGN contamination, and diffuse ionized gas (DIG) based on publicly available multi-wavelength data. Especially, given the extended nature and the possible non-negligible contribution to the total SFR, a careful consideration of DIG is essential. With a cross-calibration between two corrected ionized gas tracers (free-free continuum and Paα), the total SFR of the NGC 1068 disk is estimated to be 3.2 ± 0.5 M☉ yr−1, one-third of the SFR without accounting for DIG (9.1 ± 1.4 M☉ yr−1). We confirmed high SFR around the southern bar-end and the corotation radius, which is consistent with the previous SFR measurements. In addition, our total SFR exceeds the total SFR based on 8 µm dust emission by a factor of 1.5. We attribute this discrepancy to the differences in the young stars at different stages of evolution traced by each tracer and their respective timescales. This study provides an example to address the various uncertainties in conventional SFR measurements and their potential to lead to significant SFR miscalculations. © 2024, CC0.

Land use changes that are not under its designation (carrying capacity and capacity) will cause environmental degradation such as erosion. Erosion that occurs, in general, will result in a reduction in soil fertility, a reduction in soil volume, and may result in silting/sedimentation and a decrease in water quality due to an increase in Total Suspended Solid (TSS) levels. The purpose of this study was to determine the Erosion Hazard Level (EHL) that occurred around the oxbow lake and the impact caused by the erosion on the sustainability of the function of the oxbow lake. The methods used in this research are field survey and mapping methods, laboratory analysis methods, and spatial analysis methods on topography and bathymetry as well as Sentinel Satellite Imagery to find out the estimated size of the existing TSS. Erosion rate measurements were carried out using the erosion measuring stick method to measure soil loss over a certain time. Based on the results of the study, it was found that there were two TBE in the study area, including areas with Very Heavy TBE (SB) due to having soil solum > 90 cm and erosion of 653.01 tons/ha/yr. (PME 1), 581.34 tons/ha /yr. (PME 2), and 1022 tons/ha/yr. (PME 3) (> 480 tons/ha/yr.); and areas with heavy TBE (B) due to having soil solum > 90 cm and erosion of 387.80 tons/ha/year (180 - 480 tons/ha/year). The impact of erosion can also result in silting/sedimentation in the oxbow lake so that it can indirectly lead to a reduction in oxbow lake capacity/reservoir and an increase in the TSS parameter which is expected to continue due to an increase in the trendline both in the amount of rainfall and the average rain that occurred in 3 years. and in 2022 (January – June).

Experimental data on the compressive strength σmax versus strain rate Ε eng for metallic glasses undergoing uniaxial compression shows significantly different behavior for different alloys. For some metallic glasses, σmax decreases with increasing Ε eng, for others, σmax increases with increasing Ε eng, and for others σmax versus Ε eng is nonmonotonic. Using numerical simulations of metallic glasses undergoing uniaxial compression at nonzero strain rate and temperature, we show that they obey a universal relation for the compressive strength versus temperature, which determines their mechanical response. At low Ε eng, increasing strain rate leads to increases in temperature and decreases in σmax∗, whereas at high Ε eng, increasing strain rate leads to decreases in temperature and increases in σmax∗. This non-monotonic behavior of σmax∗ versus temperature causes the nonmonotonic behavior of σmax∗ versus Ε eng. Variations in the internal dissipation change the characteristic strain rate at which the nonmonotonic behavior occurs. These results are general for a wide range of metallic glasses with different atomic interactions, damping coefficients, and chemical compositions. © 2022, CC BY.
