Three Recent Publications in Nature Communications (March & April 2019)
The Computer Science Department, led by the quantum information research group and the bioinformatics algorithm lab, has recently published three articles in Nature Communications.

Nature Communications is an open access journal that publishes high-quality research from all areas of the natural sciences. Papers published by the journal represent important advances of significance to specialists within each field.

The 3 publications are:

Quantum memory: making the most of a precious resource
Our current information technology is based on classical bits, basic units of information that can have two states, either 0 or 1. All the information stored into our computers, from emails to photos and videos, is encoded into combinations of millions of zeros and ones...

New Sparsity Models for Image Processing
Many tasks in image processing need to manipulate images in a spatially varying manner. For example, the quality of different image regions may vary (e.g. a dark face over a bright background), and during image enhancement, it is critical to locally enhance important regions...

Face Sketch Synthesis
A sketch is a freehand drawing that is often used to graphically demonstrate an image, idea or principle. An experienced visual artist is able to draw a sketch rapidly; however, sketching a complex object or a detailed human face can be difficult and time-consuming for...

Distributed Algorithms in Wireless Ad-Hoc Networks
Smartphones and smartpads are everywhere. They connect people together and let people surf the Internet anywhere anytime via wireless access points. Research on wireless communication is therefore timely and important. In this project, we consider a special kind of wireless networks – wireless ad-hoc networks...

Planar Paneling in Architecture Design
The use of freeform surfaces is gaining increasing popularity in architecture design, one reason being that curved facades are often more appealing than the commonly found planar walls. After a freeform facade has been designed, the next step is to partition the facade into small pieces, each of which will...

De Novo Genome Assembly
DeoxyriboNucleic Acid (DNA) is a chain of nucleotides that contains genetic information of all known living organisms. There are four kinds of nucleotides, adenine (A), cytosine (C), guanine (G) and thymine (T). Each species in the world can be represented by by different DNA sequences, called genomes, with lengths vary from...

Uncertain Database Management
In applications such as location-based services, natural habitat monitoring, web data integration, and biometric applications, the values of the underlying data are inherently noisy or imprecise. Consider a location-based application that provides querying facilities on geographical objects...
