Nonequilibrium Statistical Mechanics of the Zero-Range Process and Related Models

open access: yes, 2005
We review recent progress on the zero-range process, a model of interacting particles which hop between the sites of a lattice with rates that depend on the occupancy of the departure site.

Energy Management in Zone Routing Protocol (ZRP) [PDF]

open access: yes, 2012
Ad hoc networks are wireless networks without a fixed infrastructure, and are usually established on a temporary basis for a specific application like emergency rescue or battle field communication. Energy management in wireless networks is the process of managing the sources and consumers of energy in a node or in the network as a whole for enhancing ...

Emerging Heterogeneous Catalysis for Valorization of Biomass‐Derived Platform Molecules: The Systematic Review Toward Sustainable Biorefinery Applications

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
Recent advances in heterogeneous catalysis for biomass valorization are highlighted, focusing on furfural, hydroxymethylfurfural (HMF), levulinic acid and glycerol conversion into fuels and chemicals. Metal oxides, zeolites, metal–organic frameworks (MOFs), porous organic polymers (POPs), carbons, and supported metals are compared, emphasizing acid ...

Digital Adaptive Learning in Secondary Mathematics: A Qualitative Interview Study With Austrian Teachers on Perceptions, Needs, and Implementations

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.
ABSTRACT Background One of the advances in learning with technology is digital adaptive learning (AL) materials for mathematics. Although empirical studies have shown the benefits of AL for learners and teachers, little research has been done on teachers' perceptions and needs of digital AL and their plans for implementation in mathematics classrooms ...

The partially asymmetric zero range process with quenched disorder

open access: yes, 2005
We consider the one-dimensional partially asymmetric zero range process where the hopping rates as well as the easy direction of hopping are random variables.

Analysis of Jellyfish Reorder Attack on ZRP

open access: yesInternational Journal of Computer Applications, 2015
MANETs are more susceptible to attacks than a wired network. High mobility, lack of central administration, etc. are some of the main causes. One of the DOS attacks known as Jellyfish Attack is difficult to analyze as well as to detect in MANETs as Jellyfisher nodes follow all the protocol rules.

The Impact of Black-Hole Attack on ZRP Protocol [PDF]

open access: yesInternational Journal of Advanced Computer Science and Applications, 2016
le manque d'infrastructure dans les réseaux ad hoc facilite leur déploiement. Chaque nœud d'un réseau ad hoc peut acheminer des données à l'aide d'un protocole de routage, ce qui diminue le niveau de sécurité. Les réseaux ad hoc sont exposés à plusieurs attaques telles que l'attaque par trou noir. Dans cet article, une étude a été faite sur l'impact de

Informational Efficiency in Cryptocurrency Markets: A Bibliometric and Thematic Literature Review (2015–2024)

open access: yesJournal of Economic Surveys, Volume 40, Issue 1, Page 443-468, February 2026.
ABSTRACT Cryptocurrency markets are known for their wide price fluctuations, lack of central control, and fast‐paced development. These characteristics present serious challenges to traditional theories about how markets work and how prices reflect available information.
