Spectroscopic evidence of odd frequency superconducting order | Spin filter superconducting S/I/N tunnel junctions (NbN/GdN/TiN) show a
robust and pronounced zero bias conductance peak at low temperatures, the
magnitude of which is several times the normal state conductance of the
junction. Such a conductance anomaly is representative of unconventional
superconductivity and is in... | 0 | 1 | 0 | 0 | 0 | 0 |
Double spend races | We correct the double spend race analysis given in Nakamoto's foundational
Bitcoin article and give a closed-form formula for the probability of success
of a double spend attack using the Regularized Incomplete Beta Function. We
give a proof of the exponential decay on the number of confirmations, often
cited in the ... | 1 | 0 | 1 | 0 | 0 | 0 |
An Asymptotic Analysis of Queues with Delayed Information and Time Varying Arrival Rates | Understanding how delayed information impacts queueing systems is an
important area of research. However, much of the current literature neglects
one important feature of many queueing systems, namely non-stationary arrivals.
Non-stationary arrivals model the fact that customers tend to access services
during certain... | 0 | 0 | 1 | 0 | 0 | 0 |
Effect of mixed pinning landscapes produced by 6 MeV Oxygen irradiation on the resulting critical current densities J$_c$ in 1.3 $μ$m thick GdBa$_2$Cu$_3$O$_{7-d}$ coated conductors grown by co-evaporation | We report the influence of crystalline defects introduced by 6 MeV
$^{16}$O$^{3+}$ irradiation on the critical current densities J$_c$ and flux
creep rates in 1.3 $\mu$m thick GdBa$_2$Cu$_3$O$_{7-d}$ coated conductor

Merge or Not? Learning to Group Faces via Imitation Learning | Given a large number of unlabeled face images, face grouping aims at
clustering the images into individual identities present in the data. This task
remains a challenging problem despite the remarkable capability of deep
learning approaches in learning face representation. In particular, grouping
results can still be... | 1 | 0 | 0 | 0 | 0 | 0 |
Entropic Causality and Greedy Minimum Entropy Coupling | We study the problem of identifying the causal relationship between two
discrete random variables from observational data. We recently proposed a novel
framework called entropic causality that works in a very general functional
model but makes the assumption that the unobserved exogenous variable has small
entropy in... | 1 | 0 | 0 | 1 | 0 | 0 |
When few survive to tell the tale: thymus and gonad as auditioning organs: historical overview | Unlike other organs, the thymus and gonads generate non-uniform cell
populations, many members of which perish, and a few survive. While it is
recognized that thymic cells are 'audited' to optimize an organism's immune
repertoire, whether gametogenesis could be orchestrated similarly to favour
high quality gametes is... | 0 | 0 | 0 | 0 | 1 | 0 |
SfMLearner++: Learning Monocular Depth & Ego-Motion using Meaningful Geometric Constraints | Most geometric approaches to monocular Visual Odometry (VO) provide robust
pose estimates, but sparse or semi-dense depth estimates. Off late, deep
methods have shown good performance in generating dense depths and VO from
monocular images by optimizing the photometric consistency between images.

Approximate Bayesian inference as a gauge theory | In a published paper [Sengupta, 2016], we have proposed that the brain (and
other self-organized biological and artificial systems) can be characterized
via the mathematical apparatus of a gauge theory. The picture that emerges from
this approach suggests that any biological system (from a neuron to an
organism) can ... | 1 | 0 | 0 | 0 | 0 | 0 |
DROPWAT: an Invisible Network Flow Watermark for Data Exfiltration Traceback | Watermarking techniques have been proposed during the last 10 years as an
approach to trace network flows for intrusion detection purposes. These
techniques aim to impress a hidden signature on a traffic flow. A central
property of network flow watermarking is invisibility, i.e., the ability to go

Outage Analysis of Offloading in Heterogeneous Networks: Composite Fading Channels | Small cells deployment is one of the most significant long-term strategic
policies of the mobile network operators. In heterogeneous networks (HetNets),
small cells serve as offloading spots in the radio access network to offload
macro users (MUs) and their associated traffic from congested macrocells. In

StackGAN++: Realistic Image Synthesis with Stacked Generative Adversarial Networks | Although Generative Adversarial Networks (GANs) have shown remarkable success

aiming at generating high-resolution photo-realistic images. First, we propose

Towards Secure and Safe Appified Automated Vehicles | The advancement in Autonomous Vehicles (AVs) has created an enormous market

Equidimensional adic eigenvarieties for groups with discrete series | We extend Urban's construction of eigenvarieties for reductive groups $G$
such that $G(\mathbb{R})$ has discrete series to include characteristic $p$

we define a notion of "locally analytic" functions and distributions on a

Latent Association Mining in Binary Data | We consider the problem of identifying groups of mutually associated

The Supernova -- Supernova Remnant Connection | Many aspects of the progenitor systems, environments, and explosion dynamics

DSVO: Direct Stereo Visual Odometry | This paper proposes a novel approach to stereo visual odometry without stereo
