The Diversity, Composition, and Putative Functions of Gill-Associated Bacteria of Bathymodiolin Mussel and Vesicomyid Clam from Haima Cold Seep, South China Sea

open access: yesMicroorganisms, 2020
The Haima cold seep, which is one of the two active cold seeps in the South China Sea, is known for its great ecological importance. The seep bivalves are assumed to depend mainly on their bacterial symbiosis for survival and growth. However, information

Inverse nodal problem for a class of nonlocal sturm‐liouville operator

open access: yesMathematical Modelling and Analysis, 2010
Inverse nodal problem consists in constructing operators from the given nodes (zeros) of their eigenfunctions. In this work, the Sturm‐Liouville problem with one classical boundary condition and another nonlocal integral boundary condition is considered.

Flow in Fractured Porous Media Modeled in Closed-Form: Augmentation of Prior Solution and Side-Stepping Inconvenient Branch Cut Locations

open access: yesFluids, 2020
Carefully chosen complex variable formulations can solve flow in fractured porous media. Such a calculus approach is attractive, because the gridless method allows for fast, high-resolution model results.

Network weight and time-varying potential function for obstacle avoidance of swarm robots in column formation

open access: yesSICE Journal of Control, Measurement, and System Integration, 2022
This paper proposes network weight functions and time-varying potential functions for obstacle avoidance of swarm robots in column formation. We consider a potential function whose exponent is the distance between the robots and the obstacle for obstacle

Power Line Extraction From Aerial Images Using Object-Based Markov Random Field With Anisotropic Weighted Penalty

open access: yesIEEE Access, 2019
The extraction of power line plays a key role in power line inspection by Unmanned Aerial Vehicles (UAVs). While it is challenging to extract power lines in aerial images because of the weak targets and the complex background.
