Evaluating Voltage Islands in CMPs under Process Variations (2008)
Abhishek Das, Serkan Ozdemir, Gokhan Memik, Alok Choudhary
Parameter variations are a major factor causing powerperformance asymmetry in chip multiprocessors. In this paper, we analyze the effects of with-in-die (WID) process variations on chip multicore...

As transistor feature sizes continue to shrink into the sub-90nm range and beyond, the effects of process variations on critical path delay have amplified. A common concept to remedy the effects of...
Microarchitectures for Managing Chip Revenues under Process Variations (2007)
Abhishek Das, Serkan Ozdemir, Gokhan Memik, Joseph Zambreno, Alok Choudhary
Abstract—As transistor feature sizes continue to shrink into the sub-90nm range and beyond, the effects of process variations on critical path delay and chip yields have amplified. A common concept...

Learning invariant features in a set of similar fitness landscapes for speedup
David Nguyen, Abhishek Das, Gokhan Memik, Alok Choudhary
In this paper, we develop an architecture for principal component analysis (PCA) to be used as an outlier detection method for high-speed network intrusion detection systems (NIDS). PCA is a common...
Evaluating the imagine stream architecture (2004)
Jung Ho Ahn, William J. Dally, Brucek Khailany, Ujval J. Kapasi, Abhishek Das
This paper describes an experimental evaluation of the prototype Imagine stream processor. Imagine [8] is a stream processor that employs a two-level register hierarchy with 9.7 Kbytes of local...
Merrimac: Supercomputing with Streams (2003)
William Dally Patrick, Patrick Hanrahan, Mattan Erez, Timothy J. Knight, François Labonté, Jung-ho Ahn, ...
Merrimac uses stream architecture and advanced interconnection networks to give an order of magnitude more performance per unit cost than cluster-based scientific computers built from the same...
Enhancing Performance of Asynchronous Data Traffic over the Bluetooth Wireless Ad-hoc Network (2001)
Abhishek Das, Abhishek Ghose, Ashu Razdan, Huzur Saran, Rajeev Shorey
Abstract—Emerging technologies such as Bluetooth are expected to become a ubiquitous solution for providing short range, low power, low cost, pico-cellular wireless connectivity. Bluetooth is a...

Hepatitis B virus (HBV) causes chronic infection in more than 350 million people worldwide. It replicates in hepatocytes but is non-cytopathic; liver damage is thought to be immune mediated. Here, we...
Bim-mediated deletion of antigen-specific CD8+ T cells in patients unable to control HBV infection
Lopes, A. Ross, Kellam, Paul, Das, Abhishek, Dunn, Claire, Kwan, Antonia, Turner, Joanna, ...
HBV-specific CD8+ T cells are critical for a successful immune response to HBV infection. They are markedly diminished in number in patients who fail to control the virus, but the mechanisms...
Functional skewing of the global CD8 T cell population in chronic hepatitis B virus infection
Das, Abhishek, Hoare, Matthew, Davies, Nathan, Lopes, A. Ross, Dunn, Claire, Kennedy, Patrick T.F., ...
The inflamed liver in chronic hepatitis B virus (HBV) infection (CHB) is characterized by a large influx of non–virus-specific CD8 T cells. Little is known about the functional capacity of these...
