The sexual network topology of individuals and their communities may affect the spread of infectious disease both within and across specific populations. To better understand this process, we collected ego-centric data on the personal sexual networks of 175 young men who have sex with men. Respondents were asked to nominate...
Milgram’s small-world experiments provided evidence for six degrees of separation, only a chain of five contacts separates any two random people. In theory, this small-world phenomenon is prevalent from a network structure perspective. However, empirical evidence shows that successful message chains are occasional, and the length of message chains are...
Developmental dyslexia cannot currently be diagnosed until a child has failed to learn to read as expected. Researchers have sought to find neural measures that may help predict a child’s later reading ability. One of these measures is the mismatch negativity (MMN), an event-related potential (ERP) component elicited by an...
Objectives: Poor infant health is associated with lower wellbeing later in life. Food insecurity has been associated with higher rates of some morbidities in young children. However, this relationship has not been well studied in infants younger than six months or in Kenya. Thus, we sought to determine the relationship...
Numerical simulations have shown that black holes (BHs) have significant influence on the evolution of globular clusters (GCs), and therefore shape their observational features. Recently, a BH-main sequence star (MS) binary system has been observed in the Milky Way GC NGC 3201. Our group uses Cluster Monte Carlo (CMC) code...
The advent of next-generation sequencing has made it increasingly feasible to survey microbes in situ, including inside buildings where many people spend extended periods of time. Microbes in buildings, and specifically in dust, are linked to various health outcomes, and the amount of antimicrobial chemicals in dust is associated to...
Air pollution increases mortality risk up to 18 percent due to cardiovascular causes. Poor air quality occurs more when meteorological components prevent the dispersal of pollutants in the lower atmosphere. The atmospheric and hydrological patterns change as global warming alters the pattern of circulations seasonally. The purpose of this study...
Investigating the drug response at the transcriptional level is powerful for understanding the mechanism of drug adverse effects, elucidating inter-individual drug response variability and developing personalized therapies. However, drug perturbation experiments are limited to immortal cell lines which do not reflect the true physiology and gene expression of the liver,...
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...
The search for life beyond Earth is one of the big questions in the modern science community, and a primary motivation behind a range of NASA's ground-based and space-bourne missions. In the near future, the James Webb Space Telescope, LUVOIR, and HabEx will characterize the atmospheres of nearby Earth-like exoplanets....
