A tight-binding-based microscopic theory is developed that accounts for quasilinear conduction bands appearing commonly in transparent conducting oxides. It is found that the interaction between oxygen p and metal s orbtials plays a critical role in determining the band structure around the conduction-band minimum. Under certain types of short-range orders, the tight-binding model universally leads to a dispersion relation which corresponds to that of the massive Dirac particle. The impact of the graphenelike band structure is demonstrated by evaluating the electron mobility of highly doped n-type ZnO.

Background: Traumatic brain injury (TBI) is considered a major cause of death globally, resulting from trauma. Decompressive craniectomy (DC) may improve functional outcomes in patients with TBI and its associated complications. This study was designed to determine safety and efficacy of DC in improving clinical outcomes in TBI patients compared to standard therapy.

Transgender and nonbinary people (TNB) experienced a disproportionate burden of poor health and socioeconomic outcomes resulting from the coronavirus disease 2019 (COVID-19) pandemic, largely driven by increased vulnerability due to pervasive structural discrimination. To characterize the extent and nature of TNB inclusivity within COVID-19 research, we conducted a scoping review of studies published in English from 2019-2022 reporting COVID-19 pandemic impacts on TNB individuals in the United States. We searched PubMed (PubMed.

In two-dimensional (2D) chiral metal-halide perovskites (MHPs), chiral organic spacers induce structural chirality and chiroptical properties in the metal-halide sublattice. This structural chirality enables reversible crystalline-glass phase transitions in (-NEA)PbBr, a prototypical chiral 2D MHP where NEA represents 1-(1-naphthyl)ethylammonium. Here, we investigate two distinct spherulite states of (-NEA)PbBr, exhibiting either radial-like or stripe-like banded patterns depending on the annealing conditions of the amorphous film.

Objective: Community engagement is an increasingly important component of ancient DNA (aDNA) research, especially when it involves archeological individuals connected to contemporary descendants or other invested communities. However, effectively explaining methods to non-specialist audiences can be challenging due to the intricacies of aDNA laboratory work. To overcome this challenge, the Anson Street African Burial Ground (ASABG) Project employed a GoPro camera to visually document the process of aDNA extraction for use in community engagement and education events.
