Reconfigurable multi-level phase shift keying encoder-decoder for all-optical networks [PDF]

, 2003
We demonstrate the application of a uniform Bragg grating as a dynamically reconfigurable phase encoder-decoder for optical systems. Precise discrete phase modulation between chips is obtained simply by heating segments along the grating with fine ...

Frequency quantization in first-order digital phase-locked loops with frequency-modulated input [PDF]

, 2007
Presented at the International Workshop on Nonlinear Maps and their Applications (NOMA '07), INSA, Toulouse, December 13-14, 2007Frequency granularity in a digital phase-locked loop arises from quantization in the number-controlled oscillator which ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Improved Detection of Differential Phase Shift Keying through MultiSymbol

, 2005
We report an improved self-homodyne detection scheme for differential phase-shift-keying that achieves close to homodyne performance and effectively reduces the influence of nonlinear phase noise, resulting in a 1.3dB sensitivity improvement over self ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Research and Application on Variable Frequency and Phase-Shift Control Strategy of CLLLC Resonant Converter Based on LADRC

, 2023
The voltage gain range in the over-resonant region of CLLLC resonant converter under pulse frequency modulation (PFM) at light load is insufficient. Phase shift modulation (PSM) can only realize the buck function, and the load switching perturbation has ...

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Rapidly reconfigurable optical phase encoder-decoders based on fiber Bragg gratings [PDF]

, 2006
We demonstrate the capacity for fast dynamic reconfiguration of optical code-division multiple access (OCDMA) phase en/decoders based on fiber Bragg gratings and a thermal phase-tuning technique.
