Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Power reversal strategy through DC current reversal using a new bidirectional LCC HVDC system

International Journal of Electrical Power & Energy Systems
This paper presents a new Line-Commutated Converter (LCC) High-Voltage Direct Current (HVDC) topology with bidirectional current capability. Based on the proposed topology, this paper further develops a control strategy that achieves power reversal ...

The effect of the particle shape and structure on the flowability of electrolytic copper powder. III. A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current [PDF]

Journal of the Serbian Chemical Society, 2004
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Controlling current reversals in synchronized underdamped ratchets [PDF]

Journal of Physics A: Mathematical and Theoretical, 2010
Summary: A pair of underdamped ratchets, coupled via a perturbed asymmetric potential, is shown to make a transition to a fully synchronized state wherein stable controlled transport is achieved when the coupling strength exceeds a threshold at which the collective dynamics is attained.

Magnetization reversal by injection and transfer of spin: experiments and theory

, 2003
Reversing the magnetization of a ferromagnet by spin transfer from a current, rather than by applying a magnetic field, is the central idea of an extensive current research.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
