Macroscopic and structural properties of one-dimensional (1D) dipolar fluids are investigated theoretically. The equation of state is fully explored by means of analytical limiting laws, integral equations and corroborating Monte Carlo simulations. An interesting mapping with the Tonks gas (i.e. hard rods) is established at strong coupling. Crucially, we report a novel solid phase characterized by aof the pair distribution function whose range extends with increasing coupling. This discovery provides a clarified view in 1D systems and open new routes to explore theoretically as well as experimentally.

This study explores the integration of sexual and reproductive health (SRH) education in Sri Lanka, utilizing the Health Belief Model (HBM) to predict the perceived quality of SRH education among non-state undergraduate students. In many Asian countries, including Sri Lanka, cultural resistance and skepticism often challenge SRH education initiatives. The research is based on a questionnaire survey, examining factors influencing the perceived quality of SRH education, such as cultural norms, embarrassment, attitudes, awareness, and institutional support.

Aging and chronic inflammation are associated with overabundant myeloid-primed multipotent progenitors (MPPs) amongst hematopoietic stem and progenitor cells (HSPCs). While HSC differentiation bias has been considered a primary cause of myeloid bias, whether it is sufficient has not been quantitatively evaluated. Here, we analyzed bone marrow data from the IκB- (Nfkbia+/-Nfkbib-/-Nfkbie-/-) mouse model of inflammation with elevated NFκB activity, which shows increased myeloid-biased MPPs.

Electronic spectra for OThF have been recorded using fluorescence excitation and two-photon resonantly enhanced ionization techniques. Multiple vibronic bands were observed in the 340-460 nm range. Dispersed fluorescence spectra provided ground state vibrational constants and evidence of extensive vibronic state mixing at higher excitation energies.

Digital exclusion is a global issue that disproportionately affects older individuals especially in low- and middle-income nations. However, there is a wide gap in current research regarding the impact of digital exclusion on the mental health of older adults in both high-income and low- and middle-income countries. We analyzed data from 5 longitudinal cohorts: the Health and Retirement Study (HRS), the English Longitudinal Study of Aging (ELSA), the Survey of Health, Ageing and Retirement in Europe (SHARE), the China Health and Retirement Longitudinal Study (CHARLS), and the Mexican Health and Aging Study (MHAS).

Antiretroviral therapy (ART) use and HIV suppression among people living with HIV (PLHIV) are critical for HIV control and prevention. Extreme restrictions on movement early during the COVID-19 pandemic in Uganda may have impeded the ability to initiate and sustain access to and use of ART. From our stepped-wedge cluster-randomized trial of an integrated PrEP and ART intervention for HIV-serodifferent couples at 12 ART clinics in Uganda, we identified participants who enrolled and had a 6-month post-ART initiation viral load measured before the beginning of the first COVID-19 lockdown (Period 1), participants whose enrollment and 6-month viral load measurement straddled pre-COVID and COVID lockdown times (Period 2), and participants whose enrollment and 6-month viral load were quantified entirely during COVID-19 (Period 3).
