Wireless sensor network design through genetic algorithm [PDF]

Journal of Artificial Intelligence and Data Mining, 2014
In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design.

Securing Cluster Formation and Cluster Head Elections in Wireless Sensor Networks

International Journal of Communication Networks and Information Security (IJCNIS), 2022
In wireless sensor networks, clustering plays a very important role for energy savings at each node because it reduces the number of transmissions through TDMA based communication. For secure clustering, it is very crucial to find compromised nodes and remove them during the initial cluster formation process.

ARSH-FATI: A Novel Metaheuristic for Cluster Head Selection in Wireless Sensor Networks

IEEE Systems Journal, 2020
Wireless sensor network (WSN) consists of a large number of sensor nodes distributed over a certain target area. The WSN plays a vital role in surveillance, advanced healthcare, and commercialized industrial automation. Enhancing energy-efficiency of the

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Radiologic Evaluation of Paranasal Sinuses in Sickle Cell Anemia and Thalassemia: Case–Control Study

Laryngoscope Investigative Otolaryngology
Background Sickle cell disease and thalassemia are inherited hematological disorders that are common worldwide. These patients suffer from chronic hemolytic anemia, which can result in bone marrow dysfunction and, in rare cases, extramedullary ...

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Research on routing optimization of WSNs based on improved LEACH protocol

EURASIP Journal on Wireless Communications and Networking, 2019
LEACH routing protocol equalizes the energy consumption of the network by randomly selecting cluster head nodes in a loop, which will lead to the defect of unstable network operation.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Data Transmission with Reduced Delay for Distributed Acoustic Sensors

, 2015
This paper proposes a channel access control scheme fit to dense acoustic sensor nodes in a sensor network. In the considered scenario, multiple acoustic sensor nodes within communication range of a cluster head are grouped into clusters. Acoustic sensor
