Transient Slow Slip Characteristics of Frictional-Viscous Subduction Megathrust Shear Zones
(2021)AGU AdvancesThe deep roots of subduction megathrusts exhibit aseismic slow slip events, commonly accompanied by tectonic tremor. Observations from exhumed rocks suggest this region of the subduction interface is a shear zone with frictional lenses embedded in a viscous matrix. Here, we use numerical models to explore the transient slip characteristics of finite-width frictional-viscous megathrust shear zones. Our model utilizes an invariant, ...Journal Article -
Electrohydrodynamic drying: Can we scale-up the technology to make dried fruits and vegetables more nutritious and appealing?
(2021)Comprehensive Reviews in Food Science and Food SafetyElectrohydrodynamic (EHD) drying is a promising technology to better preserve the nutritional content and sensory appeal of dried fruits and vegetables. To successfully scale up this technology, we need to rethink the current EHD dryer designs. There is also a significant potential to further enhance the nutritional content and sensory quality of the dried products by optimizing EHD process parameters. This study particularly highlights ...Journal Article -
Predicting Subjective Recovery from Lower Limb Surgery Using Consumer Wearables
(2020)Digital BiomarkersIntroduction: A major challenge in the monitoring of rehabilitation is the lack of long-term individual baseline data which would enable accurate and objective assessment of functional recovery. Consumer-grade wearable devices enable the tracking of individual everyday functioning prior to illness or other medical events which necessitate the monitoring of recovery trajectories. Methods: For 1,324 individuals who underwent surgery on a ...Journal Article -
Defective Satellite DNA Clustering into Chromocenters Underlies Hybrid Incompatibility in Drosophila
(2021)Molecular Biology and EvolutionAlthough rapid evolution of pericentromeric satellite DNA repeats is theorized to promote hybrid incompatibility (HI) (Yunis and Yasmineh 1971; Henikoff et al. 2001; Ferree and Barbash 2009; Sawamura 2012; Jagannathan and Yamashita 2017), how divergent repeats affect hybrid cells remains poorly understood. Recently, we demonstrated that sequence-specific DNA-binding proteins cluster satellite DNA from multiple chromosomes into “chromocenters,” ...Journal Article -
Garnet petrochronology reveals thVesuviuse lifetime and dynamics of phonolitic magma chambers at Somma-Vesuvius
(2022)Science AdvancesSomma-Vesuvius is one of the most iconic active volcanoes with historic and archeological records of numerous hazardous eruptions. Petrologic studies of eruptive products provide insights into the evolution of the magma reservoir before eruption. Here, we quantify the duration of shallow crustal storage and document the evolution of phonolitic magmas before major eruptions of Somma-Vesuvius. Garnet uranium-thorium petrochronology suggests ...Journal Article -
Are Land-Use Change Emissions in Southeast Asia Decreasing or Increasing?
(2022)Global Biogeochemical CyclesSoutheast Asia is a region known for active land-use changes (LUC) over the past 60 years; yet, how trends in net CO2 uptake and release resulting from LUC activities (net LUC flux) have changed through past decades remains uncertain. The level of uncertainty in net LUC flux from process-based models is so high that it cannot be concluded that newer estimates are necessarily more reliable than older ones. Here, we examined net LUC flux ...Journal Article -
CELLULOSE SYNTHASE INTERACTING 1 is required for wood mechanics and leaf morphology in aspen
(2020)The Plant JournalCellulose microfibrils synthesized by CELLULOSE SYNTHASE COMPLEXES (CSCs) are the main load-bearing polymers in wood. CELLULOSE SYNTHASE INTERACTING1 (CSI1) connects CSCs with cortical microtubules, which align with cellulose microfibrils. Mechanical properties of wood are dependent on cellulose microfibril alignment and structure in the cell walls, but the molecular mechanism(s) defining these features is unknown. Herein, we investigated ...Journal Article -
Enriching problem-solving followed by instruction with explanatory accounts of emotions
(2022)Journal of the Learning SciencesBackground Problem-solving followed by instruction (PS-I) is a powerful design shown to transform students’ conceptual understanding and transfer. Within PS-I, no research has examined how moment-by-moment determinants of affective states impact the problem-solving phase and posttest performance. Methods I develop a multimodal learning analytics pipeline to (a) infer affective states in PS-I via observable facial movements, (b) ...Journal Article -
Improving the Calibration of the Swiss Plate Geophone Bedload Monitoring System by Filtering Out Seismic Signals From Extraneous Particle Impacts
(2022)Earth and Space ScienceThe spatio-temporal variability of bedload transport processes poses considerable challenges for bedload monitoring systems. One such system, the Swiss plate geophone (SPG), has been calibrated in several gravel-bed streams using direct sampling techniques. The linear calibration coefficients linking the signal recorded by the SPG system to the transported bedload can vary between different monitoring stations by about a factor of six, ...Journal Article -
Numerical modeling of tectonic underplating in accretionary wedge systems
(2020)GeosphereMany fossil and active accretionary wedge systems show signs of tectonic underplating, which denotes accretion of underthrust material to the base of the wedge. Underplating is a viable process for thickening of the rear part of accretionary wedges, for example as a response to horizontal growth perpendicular to strike. Here, numerical experiments with a visco-elasto-plastic rheology are applied to test the importance of backstop geometry, ...Journal Article
