Lymph node and peri-lymph node stroma : phenotype and interaction with T-cells
… inside and surrounding skin-draining lymph nodes play a key role in regulating immune responses. We studied distinct populations of lymph node stromal cells from both human subjects and animal models in order to describe their phenotype and function. In the mouse model, we studied two …

Completion Lymph Node Dissection or Observation for Melanoma Sentinel Lymph Node Metastases: A Decision Analysis
… whether melanoma patients with sentinel lymph node (SLN) metastases should undergo completion lymph node dissection (CLND). Background: Randomized trial results comparing CLND with observation for patients with SLN metastases are not available. Methods: We developed a Markov model to simulate …

Learning network structure from node behavior
… Internet, large amounts of data about individual node behavior is becoming more easily available. Thus, an interesting problem is to devise algorithms to infer network structure from node behavior data. Since network sizes are enormous in typical applications, the learning problem is not tractable …

Molecular mapping of the rabbit atrioventricular node
The atrioventricular node (AVN) of the heart is responsible for the important conduction delay between atrial systole and ventricular systole. The anatomical architecture and functional properties of the AVN are complex. Ionic currents have been characterised in the AVN at both the whole tissue …

Node localization in underwater sensor networks (UWSN)
<p>"This dissertation focuses on node localization in underwater wireless sensor networks (UWSNs) where anchor nodes have knowledge of their own locations and communicate with sensor nodes in acoustic or magnetic induction (MI) means. The sensor nodes utilize the communication signals and the …

DECENTRALIZED NETWORK BANDWIDTH PREDICTION AND NODE SEARCH
… fixed infrastructure is required. Each joining node performs a limited number of sampling measurements. Second, we designed a decentralized algorithm to search for a centroid node that has high-bandwidth connections with a given set of nodes. The algorithm can find a centroid accurately and …

Interior Node Projection Techniques in Sweeping Algorithms
The enhancement of node projection techniques in sweeping is the subject of this thesis. Sweeping is a method used to produce all-hexahedral finite element meshes on certain classes of geometry. The placement of nodes in the interior of the geometry during the sweeping process remains a difficult …

Securing the Node of an Active Network
We describe the integration of secure node architecture into two active network software systems to demonstrate its flexible and innovative features and to present detailed performance results.

A node-based approach to charm-FFT
… was redesigned to utilize larger number of nodes while aiming to reduce the number of necessary communications between its components during its computations. Instead of decomposing the input FFT grid into the fine-grained objects that are distributed to the available PEs, coarser-grained …

A New Node-to-Node Approach to Contact/impact Problems for Two Dimensional Elastic Solids Subject to Finite Deformation
Problems of interest in this study are contact/impact problems wherein the implicit mid-point rule is used as the primary time stepping algorithm to find the solution incrementally. In order to conserve the system energy, the persistency condition is incorporated as the contact constraint. The …

The sophisticated architecture of the rat atrioventricular node
… spontaneously generated in the sinoatrial (SA) node propagates through the atria to reach the atrioventricular (AV) node. As the only conduction pathway between the atria and ventricles, the AV node functions to delay and regulate action potential conduction between the atria and ventricles. …

HDL implementation of a controller area network node
<p>With increasing technology inside automobiles, especially law enforcement vehicles, there is a growing need for centralized wiring and device interconnection methods. Each new technology, such as GPS navigation units and in-vehicle video systems, includes a corresponding wiring harness that …

NODE INFLUENCE IN NETWORK-BASED DISCRETE DYNAMICAL SYSTEMS
… discrete dynamical systems, where individual nodes (representing some variable of interest) are connected by edges that describe their interactions. Each node can take on different states relevant to the network under investigation (for example, a gene may be turned ON or OFF in a genetic …

Lymph node metastasis in auricular squamous cell carcinoma
… the auricle has an unusually high rate of lymph node metastases when compared to similar tumours at other sites. The lymph nodes affected are close to the base of the skull and in the neck. Development of metastasis carries a poor prognosis and most patients will subsequently die of failure of …

Node-weighted prize-collecting survivable network design problems
We consider node-weighted network design problems, in particular the survivable network design problem SNDP and its prize-collecting version PC-SNDP. The input consists of a node-weighted undirected graph $G=(V,E)$ and integral connectivity requirements $r(st)$ for each pair of nodes $st$. The goal …
