A Network Coding‐Based Braided Multipath Routing Protocol for Wireless Sensor Networks
Wireless Communications and Mobile Computing, Volume 2019, Issue 1, 2019., 2019 In wireless sensor networks (WSNs), energy efficiency can simultaneously guarantee robustness to link loss and node failure and is a key design goal of routing protocols because WSNs are strongly constrained in terms of transmission reliability, transmission delay, and energy consumption.

Instability of Vertical Constant Through Flows in Binary Mixtures in Porous Media with Large Pores
Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 A binary mixture saturating a horizontal porous layer, with large pores and uniformly heated from below, is considered. The instability of a vertical fluid motion (throughflow) when the layer is salted by one salt (either from above or from below) is analyzed.

Sturmian comparison and oscillation theorems for quasilinear elliptic equations with mixed nonlinearities via Picone-type inequality [PDF]
, 2010 A Picone-type inequality is established for quasilinear elliptic operators with mixed nonlinearities, and Sturmian comparison and oscillation theorems for quasilinear elliptic equations are derived by using the Picone-type ...

Non-local Torsion functions and Embeddings
, 2018 Given $s \in (0,1)$, we discuss the embedding of $\mathcal D^{s,p}_0(\Omega)$ in $L^q(\Omega)$. In particular, for $1\le q < p$ we deduce its compactness on all open sets $\Omega\subset \mathbb R^N$ on which it is continuous. We then relate, for all q up

Population and Development Review, EarlyView.Abstract There are striking disparities in life expectancy across sociodemographic groups in the United States, shaped by structural forces such as racism, class inequality, and policy environments. To what extent do sociodemographic characteristics structure—or fail to structure—individual lifespans? Using U.S.

Identification of Fully Measurable Grand Lebesgue Spaces
Journal of Function Spaces, Volume 2017, Issue 1, 2017., 2017 We consider the Banach function spaces, called fully measurable grand Lebesgue spaces, associated with the function norm ρ(f) = ess supx∈Xδ(x)ρp(x)(f), where ρp(x) denotes the norm of the Lebesgue space of exponent p(x), and p(·) and δ(·) are measurable functions over a measure space (X, ν), p(x)∈[1, ∞], and δ(x)∈(0,1] almost everywhere. We prove that

Local scale-invariance in ageing phenomena
, 1999 Many materials quenched into their ordered phase undergo ageing and there show dynamical scaling. For any given dynamical exponent z, this can be extended to a new form of local scale-invariance which acts as a dynamical symmetry.

Transactions of the Institute of British Geographers, Volume 51, Issue 1, March 2026.Abstract This article develops a cultural political ecology approach to disarticulations and labour unrest. The reference point for analysis is a struggle at a Whirlpool factory in Naples that the company announced would close in 2019, six months after signing an agreement with the Italian government, including a multi‐million investment plan.

Discrete Dynamics in Nature and Society, Volume 2016, Issue 1, 2016., 2016 We study the existence of nodal solutions for the following problem: −x″ = αx+ + βx− + ra(t)f(x), 0 < t < 1, x(0) = x(1) = 0, where r ≠ 0 is a parameter, a(t) ∈ C([0,1], (0, ∞)) with a(t)≢0 on any subinterval of [0,1], x+ = max{x, 0}, x− = −min{x, 0}, and α, β ∈ C[0,1]; f∈C(R,R), sf(s) > 0 for s ≠ 0, and f0, f∞ ∉ (0, ∞), where f0 = lim|s|→0f(s)/s and f∞

Advances in Mathematical Physics, Volume 2016, Issue 1, 2016., 2016 A comparison between first‐order microscopic and macroscopic differential models of crowd dynamics is established for an increasing number N of pedestrians. The novelty is the fact of considering massive agents, namely, particles whose individual mass does not become infinitesimal when N grows.
