Phenomenological Aspects of Heterotic Effective Models At One Loop

, 2003
We provide a study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories. Our investigation focuses on those models where the soft Lagrangian is dominated by loop contributions to

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Simplified TeV leptophilic dark matter in light of DAMPE data

Journal of High Energy Physics, 2018
Using a simplified framework, we attempt to explain the recent DAMPE cosmic e + + e − flux excess by leptophilic Dirac fermion dark matter (LDM). The scalar (Φ0) and vector (Φ1) mediator fields connecting LDM and Standard Model particles are discussed ...

Phenomenological models of synaptic plasticity based on spike timing

Biological cybernetics, 2008
Synaptic plasticity is considered to be the biological substrate of learning and memory. In this document we review phenomenological models of short-term and long-term synaptic plasticity, in particular spike-timing dependent plasticity (STDP).

Parity in left-right symmetric models [PDF]

, 2004
We considered parity breaking in some left-right symmetric models. We studied spontaneous and explicit parity violation in two cases with doublet and triplet Higgs scalars. The minimization condition in these two cases differ significantly. A comparative

High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks

Advanced Materials, EarlyView.
A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

On the importance of electroweak corrections for B anomalies

Journal of High Energy Physics, 2017
The growing experimental indication of Lepton Flavour Universality Violation (LFUV) both in charged- and neutral-current semileptonic B-decays, has triggered many theoretical interpretations of such non-standard phenomena.

Vector model phenomenology

Nuclear Physics B, 1991
Abstract We review the vector model, a low-energy effective theory of QCD based upon a novel realization of chiral symmetry incorporating vector mesons. After discussing some of the problems with the lowest-order phenomenological results of this model, we compute the leading log corrections to the theory's tree level predictions.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Model Building and Phenomenology of Flux-Induced Supersymmetry Breaking on D3-branes

, 2004
We study supersymmetry breaking effects induced on D3-branes at singularities by the presence of NSNS and RR 3-form fluxes. First, we discuss some local constructions of chiral models from D3-branes at singularities, as well as their global embedding in ...
