Vaccination for COVID-19 among historically underserved Latino communities in the United States: Perspectives of community health workers
(2022)A critical step to reduce the spread of COVID-19 is vaccination. We conducted a mixed methods project that used online surveys and focus groups with 64 Community Health Workers and Promotor/as (CHW/Ps) located near the U.S.-Mexico border to identify barriers and facilitators to COVID-19 vaccination among Latino communities that have been historically ... -
“Vaccine Diplomacy”: Historical Perspectives and Future Directions
(2014)Vaccine diplomacy is the branch of global health diplomacy that relies on the use or delivery of vaccines, while vaccine science diplomacy is a unique hybrid of global health and science diplomacy. Both offer innovative opportunities to promote United States (US) foreign policy and diplomatic relations between adversarial nations. Vaccine science ... -
Vacuum Bloch–Siegert shift in Landau polaritons with ultra-high cooperativity
(2018)A two-level system resonantly interacting with an a.c. magnetic or electric field constitutes the physical basis of diverse phenomena and technologies. However, Schrödinger’s equation for this seemingly simple system can be solved exactly only under the rotating-wave approximation, which neglects the counter-rotating field component. When the a.c. ... -
VALID: Custom ASIC Verification and FPGA Education Platform
(2003-06-01)This paper describes VALID, a platform for testing student designed ASICs and for teaching the basics of FPGA design. VALID is designed to maximize ease of use from a student?s perspective while maintaining enough flexibility for its use as an FPGA development and instruction platform. This system was designed entirely by students, has been successfully ... -
Validating the Rice neural network and the Wing Kp real-time models
(2014)The Rice neural network models of Kp have been running in real time at http://mms.rice.edu/realtime/forecast.html since October 2007; Dst and AE models were added to our operations in May 2010. All these models use the Boyle index as basis functions computed from ACE real time inputs. Later, two more driving functions were included in November 2012: ... -
Validation of Cardiorespiratory Fitness Measurements in Adolescents
(2019)Cardiorespiratory fitness (CRF) is an important indicator of adolescent cardiovascular well-being and future cardiometabolic health but not always feasible to measure. The purpose of this study was to estimate the concurrent validity of the non-exercise test (NET) for adolescents against the Progressive Aerobic Capacity Endurance Run (PACER®) and ... -
Valley trion dynamics in monolayerﾠMoSe2
(2016)Charged excitons called trions play an important role in the fundamental valley dynamics in newly emerging two-dimensional semiconductor materials. We use ultrafast pump-probe spectroscopy to study the valley trion dynamics in aﾠMoSe2ﾠmonolayer grown by using chemical vapor deposition. The dynamics displays an ultrafast trion formation followed by a ... -
The Value of Achievements
(2013)This article gives an account of what makes achievements valuable. Although the natural thought is that achievements are valuable because of the product, such as a cure for cancer or a work of art, I argue that the value of the product of an achievement is not sufficient to account for its overall value. Rather, I argue that achievements are valuable ... -
Value-Driven Redundancy Elimination
(1996-04)Value-driven redundancy elimination is a combination of value numbering and code motion. Value numbering is an optimization that assigns numbers to values in such a way that two values are assigned the same number if the compiler can prove they are equal. When this optimization discovers two computations that produce the same value, it can (under ... -
Valuing the Air Quality Effects of Biochar Reductions on Soil NO Emissions
(2017)While it is clear that biochar can alter soil N2O emissions, data on NO impacts are scarce. Reports range from 0 to 67% soil NO emission reductions postbiochar amendment. We use regional air quality and health cost models to assess how these soil NO reductions could influence U.S. air quality and health costs. We find that at 67% soil NO reduction, ... -
Van Allen Probes Observations of Second Harmonic Poloidal Standing Alfvén Waves
(2018)Long-lasting second-harmonic poloidal standing Alfvén waves (P2 waves) were observed by the twin Van Allen Probes (Radiation Belt Storm Probes, or RBSP) spacecraft in the noon sector of the plasmasphere, when the spacecraft were close to the magnetic equator and had a small azimuthal separation. Oscillations of proton fluxes at the wave frequency ...
