On the Homogeneity of TiN Kinetic Inductance Detectors Produced through Atomic Layer Deposition. (arXiv:1911.06419v1 [physics.ins-det])

The non-homogeneity in the critical temperature $T_{c}$ of an Microwave Kinetic Inductance Detector (MKID) could be caused by non-uniformity in the deposition process of the thin superconducting film. This produces low percent yield and frequency collision in the readout of the MKIDs. Here, we show the homogeneity that offers Atomic Layer Deposition (ALD). We report…

Sensitivity of the COHERENT Experiment to Accelerator-Produced Dark Matter. (arXiv:1911.06422v1 [hep-ex])

The COHERENT experiment is well poised to test sub-GeV dark matter models using low-energy recoil detectors sensitive to coherent elastic neutrino-nucleus scattering (CEvNS) in the $\pi$-DAR neutrino beam produced by the Spallation Neutron Source. We show how a planned 750-kg liquid argon scintillation detector would place leading limits on scalar light dark matter models, over…

Interaction of Biased Electrodes and Plasmas: Sheaths, Double Layers and Fireballs. (arXiv:1911.06424v1 [physics.plasm-ph])

Biased electrodes are common components of plasma sources and diagnostics. The plasma-electrode interaction is mediated by an intervening sheath structure that influences properties of the electrons and ions contacting the electrode surface, as well as how the electrode influences properties of the bulk plasma. A rich variety of sheath structures have been observed, including ion…

Resist or perish: fate of a microbial population subjected to a periodic presence of antimicrobial. (arXiv:1911.06425v1 [q-bio.PE])

The evolution of antimicrobial resistance can be strongly affected by variations of antimicrobial concentration. Here, we study the impact of periodic alternations of absence and presence of antimicrobial on resistance evolution in a microbial population, using a stochastic model that includes variations of both population composition and size, and fully incorporates stochastic population extinctions. We…

Origin of the instability in dynamic fracture. (arXiv:1911.06426v1 [cond-mat.soft])

Unstable growth of cracks (rough crack surface, crack branching) in dynamic fracture have long been observed in various materials. But up to now, no universally agreed-on explanation for why these instabilities happen. Here, we demonstrate that: 1) due to the non-uniform stress distribution in cracked body and the high stress region expands as crack velocity…

The Boundedness of the Ornstein-Uhlenbeck semigroup on variable Lebesgue spaces with respect to the Gaussian measure. (arXiv:1911.06375v1 [math.CA])

The main result of this work is the proof of the boundedness of the Ornstein-Uhlenbeck semigroup $ \{T_t \}_{t\geq 0} $ in $ {\mathbb R}^d $ on Gaussian variable Lebesgue spaces under a condition of regularity on $p(\cdot)$ following previous papers by E. Dalmaso R. Scotto and S. P\’erez. As a consequence of this result,…

Solving Inverse Problems by Joint Posterior Maximization with a VAE Prior. (arXiv:1911.06379v1 [stat.ML])

In this paper we address the problem of solving ill-posed inverse problems in imaging where the prior is a neural generative model. Specifically we consider the decoupled case where the prior is trained once and can be reused for many different log-concave degradation models without retraining. Whereas previous MAP-based approaches to this problem lead to…

Entanglement-assisted Quantum Codes from Cyclic Codes. (arXiv:1911.06384v1 [cs.IT])

Entanglement-assisted quantum (QUENTA) codes are a subclass of quantum error-correcting codes which use entanglement as a resource. These codes can provide error correction capability higher than the codes derived from the traditional stabilizer formalism. In this paper, it is shown a general method to construct QUENTA codes from cyclic codes. Afterwards, the method is applied…

Estimation of dynamic networks for high-dimensional nonstationary time series. (arXiv:1911.06385v1 [math.ST])

This paper is concerned with the estimation of time-varying networks for high-dimensional nonstationary time series. Two types of dynamic behaviors are considered: structural breaks (i.e., abrupt change points) and smooth changes. To simultaneously handle these two types of time-varying features, a two-step approach is proposed: multiple change point locations are first identified based on comparing…
