Strong coupling methods for lattice QCD
… numerical finite density sign problem. Strong coupling methods, expanding in the inverse gauge coupling, give rise to alternative representations of the partition function that can make the sign problem milder. This Habilitation discusses the strong coupling methods developed by the author and …

Multi-Time-Step Domain Decomposition and Coupling Methods for Non-Linear Structural Dynamics
The present multi-time-step coupling method is based on a dual Schur domain decomposition method that uses Lagrange multipliers to enforce the continuity of the solution across the interfaces between the subdomains. The subdomains can be integrated with different time steps and/or time stepping …

A Hybrid Switched-Capacitor Converter for Capacitive Wireless Power Transfer in Biomedical Applications
… C-WPT research is focused on resonant capacitive coupling methods. Such works have reported power transfer efficiency of less than 40%. In the proposed thesis, a capacitively isolated Dickson converter, a type of hybrid switched capacitor converter, will be investigated to determine if it can be …

3-D optical waveguide arrays for in-vivo optogenetics : development and application
… probe geometries with integrated waveguides. Methods were developed to assemble the multi-shank probes into a 3D format using discrete monolithic silicon pieces. Three coupling schemes were developed to couple light to both single- and multi-shank probes. For individual probes not assembled in …

Statistical Gems in AI: Toward Reliable and Efficient Intelligence
… systems. We demonstrate how hypothesis testing, coupling methods, and conformal inference can ensure that advanced artificial intelligence (AI) models operate with safety, fairness, and efficiency. First, we design hypothesis-testing frameworks that distinguish genuine reasoning from token bias, …

C2- and C3-Symmetric Meta-substituted Thienyl Benzenes: A Comparative Synthetic and Structural Study
Suzuki, Stille and Kumada coupling approaches to the syntheses of various C1- and C3- symmetric thienylbenzene compounds (A and B, respectively) are systematically compared. Novel routes are reported for the syntheses of C3-symmetric compounds using Kumada (n = 0) and Stille (n = 1) coupling …

Modeling Evolutionary Constraints and Improving Multiple Sequence Alignments using Residue Couplings
Residue coupling in protein families has received much attention as an important indicator toward predicting protein structures and revealing functional insight into proteins. Existing coupling methods identify largely pairwise couplings and express couplings over amino acid combinations, which do …

Using a high-speed plasma as a conducting channel to enable a novel antenna approach
… results for tuning. Finally, we consider feed methods for the time-varying antenna. Plasma antennas must be fed by indirect coupling due to sheath effects. The nanosecond feed pulses have wideband frequency content, so the wideband capabilities of existing coupling methods are examined. The …

Efficient enzyme coupling algorithms identify functional pathways in genome-scale metabolic models
"Flux coupling identifies sets of reactions whose fluxes are “coupled"" or correlated in genome-scale models. By identified sets of coupled reactions, modelers can 1.) reduce the dimensionality of genome-scale models, 2.) identify reactions that must be modulated together during metabolic …

Tightly coupled neutronics and thermal-hydraulics using open-source software
Coupling the neutronic and thermal-hydraulic analyses of a nuclear reactor core is important because it helps identify the most relevant safety issues. Currently all coupled computations solve the same set of governing equations using different coupling methods, which can be sorted into two …

Transmetalation from boronic esters to arylpalladium complexes without prior hydrolysis – mechanistic studies and preparative applications in the anhydrous, Suzuki-Miyaura cross-coupling reaction
… development of transition-metal catalyzed, cross-coupling reactions has fundamentally changed the way chemists think about C–C bond formation. Within the class of transition-metal catalyzed, cross coupling reactions, the Suzuki-Miyaura reaction has emerged as the most popular method because of the …
