Choke points and airway wall structure in expiratory central airway collapse are poorly defined. Computed tomography, white light bronchoscopy, endobronchial ultrasound, vibration response imaging, spirometry, impulse oscillometry, negative expiratory pressure, and intraluminal catheter airway pressure measurements were used in a patient with cough, dyspnea, and recurrent pulmonary infections....

Autonomous agents in real-time strategy (RTS) games lack an integrated framework for reasoning about choke points and regions of open space in their environment. This paper presents an algorithm which partitions the environment into a set of polygonal regions and computes optimal choke points between adjacent regions. This representation can be used as a component for AI agents to reason about ...

Biological pathways information has accumulated along with Genomic sequence data. These metabolic pathways help us in understanding network robustness and complex reaction networks. They also provide a framework for improved understanding of microbial physiology and for antimicrobial drug discovery. This article is an attempt to understand the local and global properties of metabolic networks i...

The TPC-D benchmark was developed almost 20 years ago, and even though its current existence as TPC-H could be considered superseded by TPC-DS, one can still learn from it. We focus on the technical level, summarizing the challenges posed by the TPC-H workload as we now understand them, which we call “choke points”. We identify 28 different such choke points, grouped into six categories: Aggreg...

Abstract— The Active Queue Management (AQM) is a technique that consists of ECN (Explicit Congestion notifications) in internet routers. Congestion is an important issue which researcher focuses on in the TCP network environment. AQM is a router – based mechanism for early detection of congestion inside the network. This paper provides an analysis of congestion metric with flow information in q...

Some projects of SRF guns apply the design where the cathode can be easily and quickly removed. One of the disadvantages of this design is the RF power leakage from the accelerating gun cavity cells to the cathode housing that result in the excessive cathode heating. To minimize the RF power leak different kinds of choke filters are used to protect the cathode structure. These choke filters rep...

El artículo analiza el emplazamiento de la Salsa Choke dentro en Cali; su pasaje ser una música casi desconocida y propia un sector marginal población ciudad hasta catalogarse como parte identidad caleña. Se reconstruyen a vez los itinerarios transitados por jóvenes creadores Choke, cuales ilustran deseo artistas las formas producción, circulación consumo musical contemporáneas. En tercer momen...

MOTIVATION The local and global aspects of metabolic network analyses allow us to identify enzymes or reactions that are crucial for the survival of the organism(s), therefore directing us towards the discovery of potential drug targets. RESULTS We demonstrate a new method ('load points') to rank the enzymes/metabolites in the metabolic network and propose a model to determine and rank the bi...

This thesis describes the potential use of re-entrant microwave resonant three-dimensional cavities as low-loss electrical component in strongly coupled electromechanical systems. In particular , I have investigated radiative processes as a loss mechanism of a re-entrant cavity in a geometry similar to those used in electromechanical experiments undertaken by the Lehnert lab. First, I present t...
