Two mobile agents, starting at arbitrary, possibly different times from arbitrary nodes of an unknown network, have to meet at some node. Agents move in synchronous rounds: in each round an agent can either stay at the current node or move to one of its neighbors. Agents have different labels which are positive integers. Each agent knows its own label, but not the label of the other agent. In t...

R ecognition of the possibility of ablating cardiac tissue by means of commonly used electrophysiological catheters has led to the development of the fulguration techniques. Unipolar DC (direct current) shocks delivered at the tip of a catheter by means of an ordinary defibrillator were applied to the atrioventricular node-His bundle area for control of refractory supraventricular tachycardias....

The need of polygonal elements to represent the domain is gaining interest among structural engineers. The objective is to perform static analysis and topology optimization of a given continuum domain using the rational fraction type shape functions of six node hexagonal elements. In this paper, the main focus is to perform the topology optimization of two-dimensional plate structures using Evo...

lymph node dissection is of prime importance for accurate staging of colorectal carcinomas. since a great number of small lymph nodes are missed in the traditional method, several fat clearing solutions have been introduced for easier detection of smaller lymph nodes. in this study we evaluated the efficacy of a new fat clearing solution so-called lymph node revealing solution (lnrs) in colecto...

background: the sentinel lymph node (sln) is defined as the first chain node in the lymphatic basin that receives primary lymphatic flow. if the sln is negative for metastatic disease, then other nodes are expected to be disease-free. sln techniques have been extensively applied in the staging and treatment of many tumors, including melanoma, breast and vulvar cancers. this study aims to evalua...

background: sentinel lymph node biopsy (slnb) has replaced axillary lymph node dissection (alnd) in early breast cancer patients as the first line surgical approach to axillary nodes. further dissection is performed only when sln is involved by tumor cells. however, in a significant proportion of patients, non-sentinel nodes are still not involved and axillary dissection has no additional thera...

A flooding attack in a wireless sensor network consumes the energy of the sensor node included in the path in the process of sending a persistent false packet to the base station. If a flooding attack is continuously generated, the sensor node with a low residual energy causes energy depletion and the life of the sensor networks is shortened when the number of sensor nodes having depleted energ...
