A compact and cost-effective laser-powered speckle visibility spectroscopy (SVS) device for measuring cerebral blood flow

Posted by dbos Caltech

Kavli Affiliate: Changhuei Yang | First 5 Authors: Yu Xi Huang, Simon Mahler, Maya Dickson, Aidin Abedi, Julian M. Tyszka | Summary: In the realm of cerebrovascular monitoring, primary metrics typically include blood pressure, which influences cerebral blood flow (CBF) and is contingent upon vessel radius. Measuring CBF non-invasively poses a persistent challenge, primarily attributed […]

The rigidity of eigenvalues on Kähler manifolds with positive Ricci lower bound

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Jianchun Chu, Feng Wang, Kewei Zhang, , | Summary: In this work, optimal rigidity results for eigenvalues on K"ahler manifolds with positive Ricci lower bound are established. More precisely, for those K"ahler manifolds whose first eigenvalue agrees with the Ricci lower bound, we show that the complex […]

Protocol for certifying entanglement in surface spin systems using a scanning tunneling microscope

Posted by dbos Delft

Kavli Affiliate: Sander Otte | First 5 Authors: Rik Broekhoven, Curie Lee, Soo-hyon Phark, Sander Otte, Christoph Wolf | Summary: Certifying quantum entanglement is a critical step towards realizing quantum-coherent applications of surface spin systems. In this work, we show that entanglement can be unambiguously shown in a scanning tunneling microscope (STM) with electron spin […]

On the Statistical Mechanics of Mass Accommodation at Liquid-Vapor Interfaces

Posted by dbos Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Kritanjan Polley, Kevin R. Wilson, David T. Limmer, , | Summary: We propose a framework for describing the dynamics associated with the adsorption of small molecules to liquid-vapor interfaces, using an intermediate resolution between traditional continuum theories that are bereft of molecular detail and molecular dynamics […]

Research on the knee region of cosmic ray by using a novel type of electron-neutron detector array

Posted by dbos Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Bing-Bing Li, Xin-Hua Ma, Shu-Wang Cui, Hao-Kun Chen, Tian-Lu Chen | Summary: By accurately measuring composition and energy spectrum of cosmic ray, the origin problem of so called "keen" region (energy > 1 PeV) can be solved. However, up to the present, the results of the spectrum […]
