Symmetry enriched U(1) quantum spin liquids [PDF]
, 2018 We classify and characterize three dimensional $U(1)$ quantum spin liquids (deconfined $U(1)$ gauge theories) with global symmetries. These spin liquids have an emergent gapless photon and emergent electric/magnetic excitations (which we assume are ...

Illinois Farmers Markets Using EBT: Impacts on SNAP Redemption and Market Sales
Journal of Agriculture, Food Systems, and Community Development, 2016 The number of people in the Supplemental Nutrition Assistance Program (SNAP), formerly known as food stamps, is currently at an all-time high. The switch from food stamp coupons to the Electronic Benefit Transfer (EBT) system was completed nationwide in ...

Asymptotic Freedom from Thermal and Vacuum Magnetization [PDF]
, 1996 We calculate the effective Lagrangian for a magnetic field in spinor, scalar and vector QED. Connections are then made to $SU(N_C)$ Yang--Mills theory and QCD.

Modified beam theories for bending properties of nanowires considering surface/intrinsic effects and axial extension effect [PDF]
, 2012 Several studies of the surface effect on bending properties of a nanowire (NW) have been conducted. However, these analyses are mainly based on theoretical predictions, and there is seldom integration study in combination between theoretical predictions ...

Convergence of Markov processes near saddle fixed points. [PDF]
, 2007 We consider sequences (XtN)t≥0 of Markov processes in two dimensions whose fluid limit is a stable solution of an ordinary differential equation of the form ẋt=b(xt), where for some λ, μ>0 and τ(x)=O(|x|2).

Quantifying uncertainty in calibration and clinical application of EBT-4 Gafchromic film dosimetry. [PDF]
Med PhysAbstract Background GAFchromic films (GAFs) are essential tools in radiotherapy dosimetry, but uncertainties in calibration methods limit their accuracy and hinder consistency across clinical practice. Purpose This study aimed to perform a comparative analysis of different calibration functions for GAFchromic EBT4 films in single‐ and double‐channel ...

EBT-II conceptual design study [PDF]
, 1978 The proposed EBT-II will use 48 superconducting coils to provide the required steady-state, cyclotron resonant, toroidal magnetic field of 4.3 T for electron cyclotron heating (ECH) with microwaves at 120 GHz. The peak design fields are 7.8 T in the coil, 6.0 T in the coil throat, and 3.0 T in the cavity midplane. Bulk ECH will be provided by eight 120-

Radiation Oncology, 2010 Background A modified form of high dose rate (HDR) brachytherapy has been developed called Axxent Electronic Brachytherapy (EBT). EBT uses a kilovolt X-ray source and does not require treatment in a shielded vault or a HDR afterloader unit.
