Results in PhysicsWe present a compact, systematic formulation of the dynamics of the Husimi Q- and Glauber–Sudarshan P-phase space distribution functions expressed in terms of their complementary Hamiltonian symbols: Anti-Wick for Q and Wick for P.

Stochastic Effects for the Reaction-Duffing Equation with Wick-Type Product
Advances in Mathematical Physics, 2016 We construct new explicit solutions of the Wick-type stochastic reaction-Duffing equation arising from mathematical physics with the help of the white noise theory and the system technique.

Convexity and the Euclidean Metric of Space-Time
Universe, 2017 We address the reasons why the “Wick-rotated”, positive-definite, space-time metric obeys the Pythagorean theorem. An answer is proposed based on the convexity and smoothness properties of the functional spaces purporting to provide the kinematic ...

Advanced Materials Technologies, EarlyView.A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

Gödel universe from string theory
European Physical Journal C: Particles and Fields, 2017 The Gödel universe is a direct product of a line and a three-dimensional spacetime we call G $$_\alpha $$ α . In this paper, we show that the Gödel metrics can arise as exact solutions in Einstein–Maxwell–Axion, Einstein–Proca–Axion, or Freedman–Schwarz ...

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection
Advanced Materials Technologies, EarlyView.A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Absence of submultiplicative norms for Wick-ordered operator products
Journal of Mathematical Physics, 2023 In this paper, a key problem in the rigorous formulation of the renormalization group as a continuous flow is identified. Some essential features of the operator-theoretic renormalization group of Bach, Chen, Fröhlich, and Sigal are recalled, and a family of norms associated with different Banach spaces of Hamiltonians is introduced.

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Measurement of heating coil temperature for e-cigarettes with a "top-coil" clearomizer.
PLoS ONE, 2018 ObjectivesTo determine the effect of applied power settings, coil wetness conditions, and e-liquid compositions on the coil heating temperature for e-cigarettes with a "top-coil" clearomizer, and to make associations of coil conditions with emission of ...

Making Sweat Measurable: Induction, Sampling, and Refreshment in Wearable Biofluid Sensing
Advanced Science, EarlyView.Wearable sweat sensing relies not only on chemical detection but also on controlled biofluid management. This Review integrates sweat physiology, induction strategies, and microfluidic sampling architectures, demonstrating how flux, transport, and refreshment shape measurement reliability.
