Quantum effective actions from nonperturbative worldline dynamics
, 2005 We demonstrate the feasibility of a nonperturbative analysis of quantum field theory in the worldline formalism with the help of an efficient numerical algorithm. In particular, we compute the effective action for a super-renormalizable field theory with

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Driving simulator for evaluating the effects of road geometric design on driver behavior
International Journal of Occupational and Environment Safety, 2019 The traditional approach adopted towards road safety is the analysis of risk factors that contribute to frequency or severity of traffic crashes. Many distinct elements play a role, simultaneously, in a crash occurrence, and, undoubtedly, geometric ...

Neurofeedback-Based Moral Enhancement and the Notion of Morality [PDF]
, 2017 Some skeptics question the very possibility of moral bioenhancement by arguing that if we lack a widely acceptable notion of morality, we will not be able to accept the use of a biotechnological technique as a tool for moral bioenhancement.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

The Index of Leading Indicators: "Measurement without Theory," Twenty-Five Years Later [PDF]
The index of leading economic indicators first developed by the NBER remains a popular informal forecasting tool in spite of the original criticism that its use represents "measurement without theory. " This paper seeks to evaluate the performance of the

CampProf: A Visual Performance Analysis Tool for Memory Bound GPU Kernels [PDF]
, 2010 Current GPU tools and performance models provide some common architectural insights that guide the programmers to write optimal code. We challenge these performance models, by modeling and analyzing a lesser known, but very severe performance pitfall ...

Imaging Photon Lattice States by Scanning Defect Microscopy
, 2015 Microwave photons inside lattices of coupled resonators and superconducting qubits can exhibit surprising matter-like behavior. Realizing such open-system quantum simulators presents an experimental challenge and requires new tools and measurement ...

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
