Somatic mutations render human exome and pathogen DNA more similar
Ehsan Ebrahimzadeh, Maggie Engler, David Tse +2
Immunotherapy has recently shown important clinical successes in a substantial number of oncology indications. Additionally, the tumor somatic mutation load has been shown to assoc…
Feedback Increases the Capacity of Queues with Bounded Service Times
K. R. Sahasranand, Aslan Tchamkerten
In the "Bits Through Queues" paper, it was hypothesized that full feedback always increases the capacity of first-in-first-out queues, except when the service time distribution is…
Compression with Privacy-Preserving Random Access
Venkat Chandar, Aslan Tchamkerten, Shashank Vatedka
We show that an i.i.d.\ binary source sequence can be losslessly compressed at any rate above entropy while ensuring that the decoding of any reveals no info…
Capacity-Achieving Input Distribution in Per-Sample Zero-Dispersion Model of Optical Fiber
Jihad Fahs, Aslan Tchamkerten, Mansoor I. Yousefi
The per-sample zero-dispersion channel model of the optical fiber is considered. It is shown that capacity is uniquely achieved by an input probability distribution that has contin…
Estimating a Random Walk First-Passage Time from Noisy or Delayed Observations
Marat V. Burnashev, Aslan Tchamkerten
A random walk (or a Wiener process), possibly with drift, is observed in a noisy or delayed fashion. The problem considered in this paper is to estimate the first time Ïthe random…
Local Decode and Update for Big Data Compression
Shashank Vatedka, Aslan Tchamkerten
This paper investigates data compression that simultaneously allows local decoding and local update. The main result is a universal compression scheme for memoryless sources with t…
