Recent discoveries of black hole (BH) candidates in galactic and extragalactic globular clusters (GCs) have ignited interest in understanding how BHs dynamically evolve in a GC and the number of BHs (NBH) that may still be retained by today's GCs. Numerical models show that even if stellar-mass BHs are retained...
On February 22, 2022, I gave a talk hosted by the African Studies Program of Georgetown University. Two days later, Russian battalions were sent across Ukraine’s borders by President Vladimir Putin. In real time, viewers around the world have seen immense distress unleashed on innocent citizens. In Africa, distress has...
Regulatory T (Treg) cells are required to control immune responses and maintain homeostasis, but are a significant barrier to antitumor immunity. Conversely, Treg instability, characterized by loss of the master transcription factor Foxp3 and acquisition of proinflammatory properties, can promote autoimmunity and/or facilitate more effective tumor immunity. A comprehensive understanding...
Halide perovskites, AMX3 (A = monocation, B = Ge, Sn, or Pb, and X = halogen), present a versatile class of solution-processable semiconductors made from earth abundant materials with outstanding electrical and optical properties. Their solar cell efficiencies have dramatically increased from ~9% to ~22% in less than five years...
Transposable elements (TEs) have been recognized as potentially powerful drivers of genomic evolutionary change, but factors affecting their mobility and regulation remain poorly understood. Chaperones such as Hsp90 buffer environmental perturbations by regulating protein conformation, but are also part of the PIWI-interacting RNA pathway, which regulates genomic instability arising from...
NiTi shape memory alloy (SMA) has drawn a great deal of attention for its various applications in the medical field (orthodontics, cardiovascular stents technology, etc.) and in other engineering fields (aerospace, aircraft, automotive, etc.) as it shows shape memory effect, superelasticity and biocompatibility. The fatigue-related issues, however, are pronounced in...
Affective science has long been interested in the coherence between different emotion response systems (e.g., subjective emotional experience, behavior, physiology). Although evolutionary functionalist accounts of emotion hold that emotional coherence should be related to greater adaptation, few studies have analyzed links between emotional coherence and wellbeing. Thus, in this laboratory-based...
Contemporary Ethiopian is, without question, facing enormous challenges. At the core of these challenges lay a state-building process major constituencies and elite groups were either alienated from, forced to acquiesce to, or coopted into. Unable to derive political legitimacy from democratic participation, successive governments largely relied on coercion and neopatrimonialism,...
Included in this submission are the following supplementary materials that were unable to be included in the article, but the authors would like to make available for other researchers:
● Raw data csv files and R analysis code
