Hypoxia Signals Autophagy in Tumor Cells Via AMPK Activity, Independent of HIF-1, BNIP3, and BNIP3L
Here we report that oxygen deprivation can activate the autophagic pathway in human cancer cell lines. We observed that hypoxia induced distinct cellular changes characteristic of autophagy such as an…

Image-Guided Surgical Navigation in Implant-Based Auricular Reconstruction
In cases where surgical reconstruction is not an option, placement of osseo-integrated implants for an auricular prosthesis can be done in 1 or 2 stages in a relatively short period…

Scene-Based Nonuniformity Correction Using Local Constant Statistics
Our method proposes a local-constant statistics that assumes that the temporal signal distribution is not constant at each pixel but is locally true.

Distributed joint channel assignment, routing, and scheduling for wireless mesh networks
We present the JARS (Joint channel Assignment, Routing and Scheduling) scheme for ad hoc wireless networks in which nodes are endowed with multiple radios.

The encoding of lexical implications in VerbNet
This paper describes an experience with using the information contained in VerbNet to obtain change of location inferences.

The capacity and energy efficiency of wireless ad hoc networks with multi-packet reception
We address the cost incurred in increasing the transport capacity of wireless ad hoc networks over what can be attained when sources and destinations communicate over multi-hop paths and nodes…

Building secure mashups
We argue in this position paper that although recent technological developments have begun to provide the machinery to make secure mashups possible, they have underestimated the challenges involved in making…

ON-THE-FLOW CHARACTERIZATION OF CELLS BASED ON NATIVE FLUORESCENCE SPECTROSCOPY
We have developed a compact platform that combines a microfluidic quartz channel with chip-size wavelength-selective detection which records the fluorescence of particles as they traverse the channel.

Broadcast throughput capacity of wireless Ad Hoc Networks with Multipacket Reception
Abstract We study the broadcast throughput capacity of random wireless ad hoc networks when the nodes are endowed with multipacket reception (MPR) capability. We show that, in such networks, a…
