Summary: The study demonstrated that Molibresib at a once daily dose of 75 mg did not show unexpected toxicities, with common treatment-related adverse events including thrombocytopenia, nausea, and decreased appetite. Antitumor activity was observed in NC and CRPC, although predefined clinically meaningful response rates were not met for any tumor type. Investigations into combinatorial approaches using BET inhibition to eliminate resistance to other targeted therapies are warranted.

Summary: This study aimed to determine the impact of the COVID-19 pandemic on the mental health of the Libyan population. The results showed that a significant number of respondents reported severe depressive symptoms (13.6%), severe anxiety symptoms (5.6%), and post-traumatic stress disorder (19.8%). Factors such as young age, being female, unmarried, educated, victims of domestic violence or abuse, work suspension, increased workload, financial issues, suicidal thoughts, and having a family member with or hospitalized due to COVID-19 were significantly associated with a higher likelihood of mental health disorders.

Summary: Diagenetic facies are crucial in assessing and predicting reservoirs as they provide comprehensive information on deposition, diagenesis, and petrophysical properties. This study identified six types of diagenetic facies and analyzed their influence on the quality of low-permeability tight gas reservoirs. The findings showed that diagenetic facies A, with weak compaction, and B, C, and D, with strong dissolution, are effective reservoirs with porosity greater than 6.6% and permeability greater than 0.25 - 0.6 x 10(-3) μm2. The distribution areas of these facies serve as favorable areas for tight gas exploration and are important indicators for predicting tight gas in the Upper Paleozoic Shanxi Formation in the eastern Ordos Basin. This study presents a new petrographic method with practical and economic significance for reservoir prediction and natural gas exploration.

Summary: Research on the faults and their evolutionary history in the Suhongtu-Dagu depressions since the Cretaceous provides a theoretical basis for the geological evaluation of coal seams in the Suhongtu Formation in the Yin'e Basin. Through various techniques, the study clarified the planar and profile distributions of faults, as well as their evolutionary history and the tectonic history of the depressions. The results revealed the variations in fault distribution and identified three types of faults, which played a strong role in controlling and influencing the development and modification of coal seams in the Cretaceous Suhongtu Formation.

Summary: This paper introduces two new optimization algorithms, ProxRR and FedRR, which show good performance in finite-sum minimization problems. ProxRR algorithm significantly accelerates the computation speed by evaluating the proximal operator only once per epoch. FedRR algorithm, as a special case of ProxRR applied to federated optimization, has a smaller communication footprint.
