Even though the presence of endocrine disrupting chemicals (EDCs) with thyroid hormone (TH)-like activities in the environment is a major health concern, the methods for their efficient detection and monitoring are still limited. Here we describe a n

Physical Review
We present a lattice calculation of the electromagnetic (EM) effects on the masses of light pseudoscalar mesons. The simulations employ 2+1 dynamical flavors of asqtad QCD quarks, and quenched photons. Lattice spacings vary from $\approx 0.12$ fm to

Intelligent Vehicles Symposium
We aim to determine the speed of ego-vehicle motion from a video stream. Previous work by Konda et al. [1] has shown that motion can be detected and quantified with the help of a synchrony autoencoder, which has multiplicative gating interactions int

Proceedings of The 33rd International Symposium on Lattice Field Theory — PoS(LATTICE 2015).
We give a progress report on a project aimed at a high-precision calculation of the decay constants $f_B$ and $$f_{B_s}$$ from simulations with HISQ heavy and light valence and sea quarks. Calculations are carried out with several heavy valence-quark

We compute the form factors for the $B\ensuremath{\rightarrow}K{l}^{+}{l}^{\ensuremath{-}}$ semileptonic decay process in lattice QCD using gauge-field ensembles with $2+1$ flavors of sea quark, generated by the MILC Collaboration. The ensembles span

The rare decay B→πℓ^{+}ℓ^{-} arises from b→d flavor-changing neutral currents and could be sensitive to physics beyond the standard model. Here, we present the first ab initio QCD calculation of the B→π tensor form factor f_{T}. Together

We report on the MILC Collaboration calculation of electromagnetic effects on light pseudoscalar mesons. The simulations employ asqtad staggered dynamical quarks in QCD plus quenched photons, with lattice spacings varying from 0.12 to 0.06 fm. Finite

We present results for the mass splittings of low-lying charmonium states from a calculation with Wilson clover valence quarks with the Fermilab interpretation on an asqtad sea. We use five lattice spacings and two values of the light sea quark mass
