Development of a Four‐Language Questionnaire to Investigate Environmental Risk Factors for the Development of Canine Atopic Dermatitis and to Monitor Disease Course and Progression

Veterinary Dermatology, Volume 37, Issue 1, Page 34-44, February 2026.
Background: The chronic and multifactorial character of canine atopic dermatitis (cAD) often leads to poor disease control and treatment dissatisfaction. Environmental factors are likely to contribute to the disease development and may play a more important role than assumed previously.

Optimizing The Spatial Content Caching Distribution for Device-to-Device Communications

, 2016
We study the optimal geographic content placement problem for device-to-device (D2D) networks in which the content popularity follows the Zipf law. We consider a D2D caching model where the locations of the D2D users (caches) are modeled by a Poisson ...

SDN-Controller Placement for D2D Communications [PDF]

IEEE Access, 2019
The increasing demand for data transmission resources to be handled by next generation cellular networks has led to the emergence of new technologies, such as Device-to-Device (D2D) communications and software-defined networks (SDN). D2D expands the use of resources from a location perspective and SDN enables an efficient management and control of the ...

Directed Acyclic Graph‐Based Blockchain Performance Analysis and Its Secure Operation in Opportunistic Networks

IET Software, Volume 2026, Issue 1, 2026.
Directed acyclic graph (DAG)‐based blockchain is a promising paradigm of a blockchain system. During DAG‐based consensus processes, nodes generate blocks in parallel, as well as voting YES on the previous blocks. It makes the DAG‐based blockchain a performance advantage in terms of confirmation delay and transaction throughput.
