FREQUENCY MODULATION APPROACH BASED ON SPLIT-RING RESONATOR LOADED BY VARACTOR DIODE
Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2020 In the paper, an approach to frequency modulation is presented using a split-ring resonator (SRR) loaded by a varactor diode. The modulation occurs due to the continuous time variation of capacitance of the varactor diode via changing of its bias voltage

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Detection of frequency modulation at large modulation frequencies [PDF]
The Journal of the Acoustical Society of America, 1978 Several studies have been made of the minimum frequency excursions Δf required for detection of frequency modulation, with modulation frequency fm. [E. Zwicker, Acustica, 2, 125–133 (1952) R. H. Kay and D. R. Matthews, J. Physiol. 225, 657–677 (1972)]. The graph of minimum Δf vs fm has a pronounced peak at large values of fm.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Nonquantized frequency-modulated altimeter
Journal of Research of the National Bureau of Standards, 1953 A new principle that makes possible nonquantized altitude information so that the accurate range of altimeters can be extended to include low-level operation is described. A frequency shifter is inserted between the local oscillator and the mixer in order to remove the inherent error in conventional altimeters that makes them objectionable for low ...

ACOUSTO-OPTIC FREQUENCY MODULATOR
2012 Solid-State, Actuators, and Microsystems Workshop Technical Digest, 2012 Frequency modulation of a continuous wave laser source enables generation of photons at multiple frequencies from a single pump laser. Such multiple closely spaced laser lines are important for high data rate QAM in dense-WDM networks. In this paper we present a monolithic silicon acousto-optic frequency modulator (AOFM) operating at 1.09GHz.
