Epi-two-dimensional fluid flow: a new topological paradigm for dimensionality | While a variety of fundamental differences are known to separate
two-dimensional (2D) and three-dimensional (3D) fluid flows, it is not well
understood how they are related. Conventionally, dimensional reduction is
justified by an \emph{a priori} geometrical framework; i.e., 2D flows occur

Dimensional reduction and its breakdown in the driven random field O(N) model | The critical behavior of the random field $O(N)$ model driven at a uniform
velocity is investigated at zero-temperature. From naive phenomenological
arguments, we introduce a dimensional reduction property, which relates the
large-scale behavior of the $D$-dimensional driven random field $O(N)$ model to
that of the $... | 0 | 1 | 0 | 0 | 0 | 0 |
Statistical Properties of Loss Rate Estimators in Tree Topology (2) | Four types of explicit estimators are proposed here to estimate the loss
rates of the links in a network with the tree topology and all of them are
derived by the maximum likelihood principle. One of the four is developed from
an estimator that was used but neglected because it was suspected to have a
higher variance... | 1 | 0 | 0 | 0 | 0 | 0 |
On The Communication Complexity of High-Dimensional Permutations | We study the multiparty communication complexity of high dimensional
permutations, in the Number On the Forehead (NOF) model. This model is due to

Exactly-n problem where three players receive integer inputs and need to decide

Moonshine: Distilling with Cheap Convolutions | Many engineers wish to deploy modern neural networks in memory-limited
settings; but the development of flexible methods for reducing memory use is in
its infancy, and there is little knowledge of the resulting cost-benefit. We
propose structural model distillation for memory reduction using a strategy
that produces ... | 1 | 0 | 0 | 1 | 0 | 0 |
A New Wiretap Channel Model and its Strong Secrecy Capacity | In this paper, a new wiretap channel model is proposed, where the legitimate

wiretapper has perfect access to a fixed-length subset of the transmitted
codeword symbols of her choosing. Additionally, she observes the remainder of

One-to-One Matching of RTT and Path Changes | Route selection based on performance measurements is an essential task in

Infinite horizon asymptotic average optimality for large-scale parallel server networks | We study infinite-horizon asymptotic average optimality for parallel server

Energy fluxes and spectra for turbulent and laminar flows | Two well-known turbulence models to describe the inertial and dissipative

Understanding low-temperature bulk transport in samarium hexaboride without relying on in-gap bulk states | We present a new model to explain the difference between the transport and
spectroscopy gaps in samarium hexaboride (SmB$_6$), which has been a mystery
for some time. We propose that SmB$_6$ can be modeled as an intrinsic
semiconductor with a depletion length that diverges at cryogenic temperatures.
In this model, we... | 0 | 1 | 0 | 0 | 0 | 0 |
Towards Optimal Strategy for Adaptive Probing in Incomplete Networks | We investigate a graph probing problem in which an agent has only an
incomplete view $G' \subsetneq G$ of the network and wishes to explore the
network with least effort. In each step, the agent selects a node $u$ in $G'$
to probe. After probing $u$, the agent gains the information about $u$ and its
neighbors. All th... | 1 | 1 | 0 | 0 | 0 | 0 |
Generalised Discount Functions applied to a Monte-Carlo AImu Implementation | In recent years, work has been done to develop the theory of General

One year of monitoring the Vela pulsar using a Phased Array Feed | We have observed the Vela pulsar for one year using a Phased Array Feed (PAF)

beam-weights over time, to demonstrate that pulsars can be timed over long

Using Multiple Seasonal Holt-Winters Exponential Smoothing to Predict Cloud Resource Provisioning | Elasticity is one of the key features of cloud computing that attracts many

Possible evidence for spin-transfer torque induced by spin-triplet supercurrent | Cooper pairs in superconductors are normally spin singlet. Nevertheless,
recent studies suggest that spin-triplet Cooper pairs can be created at

component, but withou... | 0 | 1 | 0 | 0 | 0 | 0 |
Robust Guaranteed-Cost Adaptive Quantum Phase Estimation | Quantum parameter estimation plays a key role in many fields like quantum

End-to-End Multi-View Networks for Text Classification | We propose a multi-view network for text classification. Our method
