Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

Advanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures

Advanced Functional Materials, EarlyView.
Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.

Bacterial Insertion Sequences

1996
While DNA has a property of being fundamentally stable as invariable genetic information, studies on gene expression and gene organization have revealed that the genome is often subject to dynamic changes. Some of these changes are brought about by mobile genetic elements which have been found in prokaryotic and eukaryotic genomes so far studied ...

Insertion of IS4 into the tnpA gone of Tn3: sequencing of the insertion site

Gene, 1990
Plasmid pMM237 lacks the deletion-forming activity associated with its Tn3 transposase-encoding gene (mpA) [Morita et al., J. Biochem. 101 (1987) 1253-1264]. Analysis of the plasmid DNA showed that pMM237 was generated by insertion of IS4 into the tnpA gene of the original plasmid pMM234.

Automatic insertion of advertisements into a video sequence

2010 International Conference on Machine Learning and Cybernetics, 2010
This paper proposes a method for seamlessly inserting virtual advertisements into a video sequence. The algorithm is based on projective geometric invariant for feature tracking that predicts the feature's location at the next frame under perspective projection.

Structural analysis of insertion sequence IS5

Nature, 1982
Among the transposable DNA elements that have been detected in bacterial genomes and plasmids1–3, the small insertion sequence (IS) elements have been recognized as a class of autonomous, basic units of transposition. IS elements are not only fully competent of transposition and able to cause several other related chromosomal aberrations such as ...

A survey of metazoan selenocysteine insertion sequences

Biochimie, 2002
The computational detection of novel selenoproteins in genomic sequences is usually achieved through identification of SECIS, a conserved secondary structure element found in the 3' UTR of animal selenoprotein mRNAs. Previous studies have used "descriptors" specifying the number of base pairs and the conserved nucleotides in SECIS to identify this ...

Insertion Sequences and Transposons

2014
Transposable elements (TEs) have been defined as DNA sequences able to insert at many sites in the genome. At present there are about 500 TEs identified in many different bacterial species. Most insertion sequence (IS) elements and transposons were discovered after their transposition into genes of interest.
