Hotspot analysis of single-vehicle lane departure crashes in North Dakota

open access: yesIATSS Research, 2023
According to the North Dakota Department of Transportation (NDDOT), 90% of the state's fatal lane departure crashes between 2015 and 2019 occurred on rural roads. Of these, 77% were single-vehicle events.

On inferred real-world fuel consumption of past decade plug-in hybrid electric vehicles in the US

open access: yesEnvironmental Research Letters, 2022
Plug-in hybrid electric vehicles (PHEVs) have powertrain architectures that seek to combine the best features of two well-known powertrains: the environmental and other benefits of electric driving of battery electric vehicles; and the fuel efficiency ...

Automatic detection of persistent physiological changes after COVID infection via wearable devices with potential for long COVID management

open access: yesScientific Reports
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can lead to post-acute sequelae of SARS-CoV-2 infection (PASC), or Long COVID, a chronic multisystemic condition with diverse symptoms and no objective diagnostic test.

Acoustic resonance coupling for directional wave control: from angle-dependent absorption to asymmetric transmission

open access: yesNew Journal of Physics, 2019
We investigate acoustic wave coupling between two resonators of very different intrinsic losses, e.g. lossy and lossless resonators as an extreme case. We find that the resonator pair placed on a reflector exhibits angle-dependent absorption, showing an ...

Active guidance in ultrasound bladder scanning using reinforcement learning

open access: yesScientific Reports
Accurate measurement of bladder volume is essential for diagnosing urinary retention and voiding dysfunction. However, finding optimal view can be challenging for less experienced operators, potentially leading to suboptimal imaging and potential ...

Robust acoustic directional sensing enabled by synergy between resonator-based sensor and deep learning

open access: yesScientific Reports
We demonstrate enhanced acoustic sensing arising from the synergy between resonator-based acoustic sensor and deep learning. We numerically verify that both vibration amplitude and phase are enhanced and preserved at and off the resonance in our compact ...

Meta-analysis of effects of age on intestinal digestibility of liquid feeds in young calves

open access: yesJDS Communications, 2021
A meta-analysis was conducted to determine the effect of age on digestibility of liquid feeds fed to preweaned Holstein calves. Calves were 4 to 76 d of age and fed whole milk or milk replacer containing all-milk protein.

Wearable-derived short sleep duration is associated with higher C-reactive protein in a placebo-controlled vaccine trial among young adults

open access: yesScientific Reports
Inadequate sleep has been associated with an increased risk of mortality and various health issues. We previously conducted a placebo-controlled vaccination trial of healthy adults who were monitored by blood samples, questionnaires, and wearable devices.
