Background: With antiretroviral therapy, people with HIV can live a normal lifespan and not transmit HIV. The Ryan White HIV/AIDS Program provides care for over half of people with HIV in the United States.
Objective: To estimate how many HIV infections could result from cessation of Ryan White services or interruptions lasting 18 to 42 months.

Background: To investigate the impact of tenofovir disoproxil fumarate (TDF) withdrawal timing on elevated postpartum alanine aminotransferase (ALT) levels and breastfeeding in pregnant women who received TDF therapy to prevent mother-to-child transmission (MTCT) of hepatitis B virus (HBV) infection.
Methods: All enrolled women began treatment with TDF during weeks 24-32 of pregnancy and were divided into three groups that stopped TDF at delivery (Group A), at 4 weeks postpartum (Group B), or at 12 weeks postpartum (Group C). The biochemical and virological markers of hepatitis B were regularly measured and compared.

Background: Upright proton therapy with compact delivery systems has the potential to reduce costs for treatments but could also lead to broadening of the beam penumbra due to energy selection close to the patient.
Purpose: This study aims at combining upright static proton arcs with additional layers of shoot-through (ST) protons to sharpen the beam penumbra and improve plan quality for such systems. An additional advantage of the method is that it provides a straightforward approach for range verification with a fixed range detector opposite the fixed proton nozzle.

Since its discovery in 2019, the characteristics of COVID-19 have also changed, increasing pressure on subway authorities to control the spread of the disease. Most scientific contributions discussed the correlation between the movement of people in the subway and the spread of the virus, and provided ways to control the spread of the virus in the subway. However, in order to balance production and safety under the easing of the epidemic, it is necessary to establish a relatively common method to evaluate the effectiveness of subway epidemic prevention management measures.

A thermo-optic 3 × 3 interferometer switch is proposed and demonstrated experimentally on silicon photonic platform. The switch is composed of two 3 × 3 multi-mode interferometer (MMI) and three interferometer arms equipped with spiral thermo-optic phase shifters (STOPS). The switching operation of the device is successfully demonstrated by heating the STOPS.
