Application of Mathematical Optimization Procedures to Intervention Effects in Structural Equation Models

Kavli Affiliate: Atsushi Yagishita | First 5 Authors: Kentaro Tanaka, Atsushi Yagishita, Masami Miyakawa, , | Summary: For a given statistical model, it often happens that it is necessary to intervene the model to reduce the variances of the output variables. In structural equation models, this can be done by changing the values of the […]

Circle-valued Morse theory for complex hyperplane arrangements

Kavli Affiliate: Toshitake Kohno | First 5 Authors: Toshitake Kohno, Andrei Pajitnov, , , | Summary: Let A be an essential complex hyperplane arrangement in an n-dimensional complex vector space V. Let H denote the union of the hyperplanes, and M denote the complement to H in V. We develop the real-valued and circle-valued Morse […]

Digital Plasmonics

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Bergin Gjonaj, Jochen Aulbach, Patrick M. Johnson, Allard P. Mosk, Kobus Kuipers | Summary: The field of plasmonics offers a route to control light fields with metallic nanostructures through the excitation of Surface Plasmon Polaritons (SPPs). These surface waves, bound to a metal dielectric interface, tightly confine […]

The shrinking instability of toroidal liquid droplets in the Stokes flow regime

Kavli Affiliate: Mark Bowick | First 5 Authors: Zhenwei Yao, Mark Bowick, , , | Summary: We analyze the stability and dynamics of toroidal liquid droplets. In addition to the Rayleigh instabilities akin to those of a cylindrical droplet there is a shrinking instability that is unique to the topology of the torus and dominates […]

DFT-based many-body analysis of electron transport through molecules

Kavli Affiliate: Joseph M. Thijssen | First 5 Authors: Fatemeh Mirjani, Joseph M. Thijssen, , , | Summary: We present a method which uses density functional theory (DFT) to treat transport through a single molecule connected to two conducting leads for the weak and intermediate coupling. This case is not accessible to standard non-equilibrium Green’s […]

Probing dark energy and neutrino mass from upcoming lensing experiments of CMB and galaxies

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Shun Saito, Atsushi Taruya, , | Summary: We discuss the synergy of the cosmic shear and CMB lensing experiments to simultaneously constrain the neutrino mass and dark energy properties. Taking fully account of the CMB lensing, cosmic shear, CMB anisotropies, and their cross correlation signals, […]

Investigating reciprocity failure in 1.7-micron cut-off HgCdTe detectors

Kavli Affiliate: Tomasz Biesiadzinski | First 5 Authors: Michael Schubnell, Tomasz Biesiadzinski, Wolfgang Lorenzon, Robert Newman, Greg Tarle | Summary: Flux dependent non-linearity (reciprocity failure) in HgCdTe NIR detectors with 1.7 micron cut-off was investigated. A dedicated test station was designed and built to measure reciprocity failure over the full dynamic range of near infrared […]

Cross-link governed dynamics of biopolymer networks

Kavli Affiliate: Martin Depken | First 5 Authors: Chase P. Broedersz, Martin Depken, Norman Y. Yao, Martin R. Pollak, David A. Weitz | Summary: Cytoskeletal networks of biopolymers are cross-linked by a variety of proteins. Experiments have shown that dynamic cross-linking with physiological linker proteins leads to complex stress relaxation and enables network flow at […]
