By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Snake venoms are integrated systems, but abundant venom proteins evolve more rapidly

BMC Genomics, 2015
BackgroundWhile many studies have shown that extracellular proteins evolve rapidly, how selection acts on them remains poorly understood. We used snake venoms to understand the interaction between ecology, expression level, and evolutionary rate in ...

Model-Based Control Design and Integration of Cyberphysical Systems: An Adaptive Cruise Control Case Study

Journal of Control Science and Engineering, 2013
The systematic design of automotive control applications is a challenging problem due to lack of understanding of the complex and tight interactions that often manifest during the integration of components from the control design phase with the ...

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Scaling Logic Area With Multitier Standard Cells

IEEE Journal on Exploratory Solid-State Computational Devices and Circuits
While the footprint of digital complementary metal-oxide–semiconductor (CMOS) circuits has continued to decrease over the years, physical limitations for further intralayer geometric scaling become apparent.

Design and Analysis of XOR Logic Gate Based on Two-Photon Absorption

MATEC Web of Conferences, 2016
Two-photon absorption with high intensity pump beam occurs in a SOA depends on fast phase change of a weak probe signal. This work analysed optical XOR logic function using two-photon absorption induced fast phase change. A rate equation for SOA and both

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Investigation of All-photonic Multiple Signals Format Converter to Carrier- suppressed Signals

MATEC Web of Conferences, 2016
Advance modulation format such as carrier suppressed return to zero (CSRZ) is used in several optical communication systems. The generation of CSRZ signal is reported in this paper by means of allphotonics format converter to its suppressed carrier ...
