Picosecond electric-field-induced threshold switching in phase-change materials

, 2016
Many chalcogenide glasses undergo a breakdown in electronic resistance above a critical field strength. Known as threshold switching, this mechanism enables field-induced crystallization in emerging phase-change memory.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Optimizing vortex pinning in YBa2Cu3O7-x superconducting films up to high magnetic fields

Communications Materials, 2022
Optimizing the microstructure of YBa2Cu3O7-x coated conductors across the magnetic field–temperature phase diagram is important for strengthening vortex pinning and thereby enhancing the critical current.

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

FEBS 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).

Automated analysis of photoelectron yield spectroscopy spectra interpreted via power laws

Science and Technology of Advanced Materials: Methods
We propose an automated method for threshold analysis in photoelectron yield spectroscopy (PYS), a technique used for measuring the ionization energy of inorganic and organic semiconductors. PYS spectra can be interpreted using the power law.

Tunable Electronic Structure in Twisted Bilayer WTe2

Frontiers in Physics, 2022
The moiré pattern restricts the electronic states of transition metal bilayers, thus extending the concept of the magic angle found in twisted bilayer graphene to semiconductors.

Dynamical Mean-Field Theory and Its Applications to Real Materials

, 2004
Dynamical mean-field theory (DMFT) is a non-perturbative technique for the investigation of correlated electron systems. Its combination with the local density approximation (LDA) has recently led to a material-specific computational scheme for the ab ...

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

FEBS 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 ...
