Tidal energy machines: A comparative life cycle assessment

open access: yes, 2013
Marine energy in the UK is currently undergoing a period of exponential growth in terms of development and implementation. The current installed tidal energy capacity of around 4MW is expected to rise to provide up to 20% of the UK’s electricity demand ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Pure radiation in space-time models that admit integration of the eikonal equation by the separation of variables method

open access: yes, 2017
We consider space-time models with pure radiation, which admit integration of the eikonal equation by the method of separation of variables. For all types of these models, the equations of the energy-momentum conservation law were integrated.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

All-optical seasonal energy saving windows

open access: yesiScience
Summary: Adaptive thermal regulation is crucial for year-round energy savings in buildings, especially in mid-latitude regions. Here, leveraging the seasonally varying angles of direct sunlight, we report a microprism-array sheet that enables seasonal ...

Energy/Delay Tradeoffs in All-Spin Logic Circuits

open access: yesIEEE Journal on Exploratory Solid-State Computational Devices and Circuits, 2016
All-spin logic (ASL) is a spin-based candidate for implementing logic in the next generation designs. The energy and the delay of ASL circuits are both inherently related to the geometric parameters of ASL gates, and the careful selection of the ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Sustainable Energy for All 2015: Progress Toward Sustainable Energy [PDF]

open access: yes, 2015
Sustainable Energy for All seeks to improve the lives of billions of people across the world and ensure a more sustainable future by working to achieve its three global objectives: universal access to energy; doubling of the rate of improvement in energy efficiency; and doubling of the share of renewable energy in the global energy mix.
