Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Covert Capacity of Non-Coherent Rayleigh-Fading Channels
, 2019 The covert capacity is characterized for a non-coherent fast Rayleigh-fading wireless channel, in which a legitimate user wishes to communicate reliably with a legitimate receiver while escaping detection from a warden.

IEEE Computer Architecture Letters, 2017 GPUs are increasingly used to accelerate the performance of not only graphics workloads, but also data intensive applications. In this paper, we explore the feasibility of covert channels in General Purpose Graphics Processing Units (GPGPUs). We consider the possibility of two colluding malicious applications using the GPGPU as a covert channel to ...

Practical covert channels for WiFi systems [PDF]
2015 IEEE Conference on Communications and Network Security (CNS), 2015 Wireless covert channels promise to exfiltrate information with high bandwidth by circumventing traditional access control mechanisms. Ideally, they are only accessible by the intended recipient and---for regular system users/operators---indistinguishable from normal operation.

Covert Communication over Adversarially Jammed Channels [PDF]
2018 IEEE Information Theory Workshop (ITW), 2018 Suppose that a transmitter Alice potentially wishes to communicate with a receiver Bob over an adversarially jammed binary channel. An active adversary James eavesdrops on their communication over a binary symmetric channel (BSC(q)), and may maliciously flip (up to) a certain fraction p of their transmitted bits based on his observations. We consider a

Aggressive prostate cancer is associated with pericyte dysfunction
Molecular Oncology, EarlyView.Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

A Covert Channel Using Named Resources [PDF]
, 2014 A network covert channel is created that uses resource names such as addresses to convey information, and that approximates typical user behavior in order to blend in with its environment.

Covert communications on renewal packet channels [PDF]
2016 54th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2016 Security and privacy are major concerns in modern communication networks. In recent years, the information theory of covert communications, where the very presence of the communication is undetectable to a watchful and determined adversary, has been of great interest.
