Summary: Intrinsic solubility, a crucial property in the pharmaceutical industry, has a significant impact on the bioavailability of small molecule drugs. However, the prediction of solubility using Artificial Intelligence (AI) is hindered by inadequate data, poor data quality, and the lack of unified measurements for AI and physics-based approaches. This study collects and curates 7 aqueous solubility datasets, resulting in improved predictions using expanded deep learning methods. In addition, the performance comparison between the enhanced Chemprop with curated data and state-of-the-art physics-based approach demonstrates similar correlation coefficients and increasing accuracy with larger datasets. Furthermore, the computational advantage of AI models allows for quick evaluation of a large set of molecules during the drug discovery stage, aiding in timely decision-making.

Summary: This letter provides an analytical framework for quantifying and evaluating high-directional terahertz communication links under pointing errors. The probability density function and cumulative distribution function of the end-to-end channel are derived in the presence of pointing errors and small-scale fading. Closed-form expressions for outage probability, average channel capacity, and symbol error rate are derived, along with asymptotic expressions. Numerical results confirm the accuracy of the analytical derivations. The effect of channel parameters on system performance is evaluated using the provided analytical expressions for outage probability, channel capacity, and symbol error rate.

Summary: As the number of electric vehicles (EVs) connected to the grid increases, there is a need to accurately predict the spatial-temporal distribution of EV charging load synchronized with traffic states. This paper proposes a novel method based on stochastic user equilibrium (SUE) and trip chain to achieve this prediction. The proposed method effectively reflects the charging and trip characteristics of different EV types while ensuring reachability, and accurately predicts overall and individual EV travel costs and total charging loads in detailed synchronous traffic states. The method shows stable convergence and remarkable prediction effectiveness, even during peak load hours and high EV penetration scenarios.

Summary: The traditional finite control set-model predictive control (FCS-MPC) is not widely accepted in the power industry due to large tracking errors and high required sampling frequency. In recent years, the double-vector-based model predictive control (DVB-MPC) incorporating deadbeat control (DBC) theory has gained attention. However, achieving satisfactory tracking performance in the universal DVB-MPC (UDVB-MPC) scheme is challenging. To address this issue, an improved double-vector-based model predictive control (IDVB-MPC) scheme is proposed in this paper. The simulation and experiment results demonstrate that IDVB-MPC significantly reduces tracking errors, total harmonic distortion (THD) of output currents, and quantitative active power ripple compared to UDVB-MPC, by approximately 50%, 20%, and 35% respectively.

Summary: This study found that the maintenance of parapatric distribution of the three viper species in the Iberian Peninsula is mainly driven by competitive exclusion, mediated by gradual changes in environmental conditions. Each species is better adapted to specific conditions, but the existence of ecotones forces them to occur sympatrically and compete for resources.

Summary: Yellow fever is a disease transmitted by mosquitoes, and in recent years, infections have occurred in areas where it was previously absent, possibly due to the rapid spread of mosquito vectors and the evolutionary dynamics of the virus in non-human primates. The study identifies the Amazon basin and southern Brazil in South America, as well as the western region of Africa, as areas with significant yellow fever transmission. It highlights the importance of monitoring yellow fever infections in primates in these regions.

Summary: An extreme weather event has disrupted the reproduction of a western spadefoot toad population at its southern range limit in Spain. This species, Pelobates cultripes, is highly impacted by climate change, and the predicted shorter breeding pond hydroperiods may reduce population recruitment. Surveys conducted during the breeding season of 2021-2022 in coastal Malaga province showed a decrease in rainfall and an increase in temperature, leading to no post-metamorphic juveniles being observed. This interruption in reproduction calls for improved monitoring of isolated amphibian populations as an early warning sign of global changes in the Mediterranean region.

Summary: In the Northern Alboran Sea, artisanal small-scale fisheries using trammel nets are facing economic losses and threats to their way of life due to interactions with alien species and dolphins. The invasion of alien seaweed Rugulopteryx okamurae and the predation of dolphins have caused damage to fishing nets, resulting in a significant loss of catchability. Close monitoring of fishermen revealed that approximately 30% of trammel sets experienced damage from unwanted interactions with seaweed and dolphins. To solve the economic issues of this activity, a large-scale management of exotic algae, involving local fishermen, is necessary.

Summary: The expansion of renewable energy production, especially wind power, is crucial for combating climate change. However, there is growing concern about its impact on biodiversity, particularly on bat populations. A study in the province of Cadiz, Spain, investigated the temporal patterns of bat fatalities in wind farms and found that mortality mainly occurred during the summer and autumn, especially in August. Future projections suggest that increasing temperatures and milder winters may lead to a rise in bat fatalities in wind farms.

Summary: The egg pattern plays an important role in avian brood parasitism, with hosts developing the ability to recognize and reject parasitic eggs, while some parasites have evolved egg mimicry. In this study, a new method based on image analysis was proposed to objectively assess the similarity of parasite eggs to host eggs. The method showed high accuracy in evaluating egg pattern similarity using the local binary pattern (LBP) and completed local binary pattern (CLBP) techniques. This method can serve as a useful tool for studying avian brood parasitism.
