Chemotherapy-drug interactions (CDIs) pose significant challenges in oncology, affecting treatment efficacy and patient safety. Despite their importance, there is a lack of validated tools to assess oncologists' knowledge of CDIs. This study aimed to develop and validate a comprehensive questionnaire to address this gap and ensure the reliability and validity of the instrument.

To consistently determine the anomalous characteristics of phthalic acid crystal (PAC) derivatives, we performed quantum dynamics simulations of the infrared spectral density of the h-PAC and d-PAC isotopomers that show up in the H/D isotopic frequency domain at two different temperatures viz. 77 and 298 K. A theoretical framework explaining the dynamical cooperative interactions within the hydrogen bonds (HBs) in the PAC crystals across a simulation of IR spectral density of the stretching band was developed.

Social media is profoundly changing our society with its unprecedented spreading power. Due to the complexity of human behaviors and the diversity of massive messages, the information-spreading dynamics are complicated, and the reported mechanisms are different and even controversial. Based on data from mainstream social media platforms, including WeChat, Weibo, and Twitter, cumulatively encompassing a total of 7.

Emerging research indicates that dehumanization may occur in couples with serious consequences; however, this research is in its infancy, and there is a need to integrate dehumanization perspectives with key theories of intimate relationships to best understand this phenomenon. Drawing on work on individuation in couples, we present an integrated framework of dehumanizing deindividuation that is characterized by derogation (viewing a partner with contempt), disregard (ignoring or overlooking a partner), and denial of autonomy (restricting a partner's self-determination). We present data from two samples highlighting the reliability and validity of a new measure, the Dehumanizing Deindividuation in Couples (DDC) scale, which was internally consistent and had excellent construct replicability.

The structure and reactivity of small methylaluminoxane (MAO) species (MeAlO)n(Me3Al)m (n = 1-8) have been investigated using DFT (M06-2X), MP2, and CCSD(T) calculations. This hierarchy of methods reveals that DFT artificially stabilizes structures containing 4-coordinate oxygen atoms while higher-level calculations demonstrate a clear preference for structures with 3-coordinate oxygen and 4-coordinate aluminum centers. Analysis of ionization pathways shows these neutral MAO molecules form anions through either methide or Me2Al+ abstraction, with the latter mechanism dominant for sheet structures (n = 5-8).
