Effective control of the error in a direct measurement of core-loss power [PDF]

, 1995
Accuracy of a direct measurement of core-loss power is severely limited in many applications by the extra phase shift between the measured voltage and current.

New technique for digital phase-shift control

Electronics Letters, 1969
A scheme for digital phase-shift control of a locked oscillator is proposed. If the required operating frequency is f and the locking frequency is nf, a reversal in phase of the locking frequency will shift the phase of the locked oscillator by π/n, under suitable conditions.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

Molecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Excitonic effects on the two-color coherent control of interband transitions in bulk semiconductors

, 2005
Quantum interference between one- and two-photon absorption pathways allows coherent control of interband transitions in unbiased bulk semiconductors; carrier population, carrier spin polarization, photocurrent injection, and spin current injection may ...

Controlled wide-range quadrature phase-shift network

Electronics Letters, 1969
A system is described which produces a 90° phase shift for a wide range of single-frequency input signals. Thus, whilst it will not handle wideband input signals, it may be useful for such applications as N-path and quadrature modulation filters where the provision of variable-frequency quadrature carrier signals allows the position of the passband to ...

A conditional-phase switch at the single-photon level

, 2002
We present an experimental realization of a two-photon conditional-phase switch, related to the ``$c$-$\phi $'' gate of quantum computation. This gate relies on quantum interference between photon pairs, generating entanglement between two optical modes ...

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.
