Wearing Masks Implies Refuting Trump?: Towards Target-specific User Stance Prediction across Events in COVID-19 and US Election 2020

Kavli Affiliate: Wei Gao | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: People who share similar opinions towards controversial topics could form an echo chamber and may share similar political views toward other topics as well. The existence of such connections, which we call connected behavior, gives researchers a unique opportunity to […]

Noninvasive in vivo photoacoustic measurement of internal jugular venous oxygenation in humans

Kavli Affiliate: Lihong V. Wang | Authors: Alejandro Garcia-Uribe, Todd N. Erpelding, Haixin Ke, Kavya Narayana Reddy, Anshuman Sharma, Lihong V. Wang | Summary: In many clinical conditions, such as head trauma, stroke, and low cardiac output states, the brain is at risk for hypoxic-ischemic injury. The metabolic rate and oxygen consumption of the brain […]

Tunable and efficient ultraviolet generation in nanophotonic lithium niobate

Kavli Affiliate: Scott K. Cushing | Authors: Emily Hwang, Nathan Harper, Ryoto Sekine, Luis Ledezma, Alireza Marandi, Scott K. Cushing | Summary: On-chip ultraviolet sources are of great interest for building compact and scalable atomic clocks, quantum computers, and spectrometers; however, few material platforms are suitable for integrated ultraviolet light generation. Of these materials, thin-film […]

Quantification of cervical elasticity during pregnancy based on transvaginal ultrasound imaging and stress measurement

Kavli Affiliate: Lihong V. Wang | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Objective: Strain elastography and shear wave elastography are two commonly used methods to quantify cervical elasticity; however, they have limitations. Strain elastography is effective in showing tissue elasticity distribution in a single image, but the absence of stress information […]

Quantum imaging of biological organisms through spatial and polarization entanglement

Kavli Affiliate: Lihong V. Wang | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Quantum imaging can potentially provide certain advantages over classical imaging. Thus far, however, the signal-to-noise ratios (SNRs) are poor; the resolvable pixel counts are low; biological organisms have not been imaged; birefringence has not been quantified. Here, we introduce […]
