Whisper-to-speech conversion using restricted Boltzmann machine arrays [PDF]

, 2014
Whispers are a natural vocal communication mechanism, in which vocal cords do not vibrate normally. Lack of glottal-induced pitch leads to low energy, and an inherent noise-like spectral distribution reduces intelligibility.

ESR1 methylation and ESR1 mutations in circulating tumor cells (CTCs) and paired plasma‐cfDNA of advanced breast cancer patients: A feasibility proof‐of‐concept study

Molecular Oncology, EarlyView.
Circulating tumor cells (CTCs) and plasma cell‐free DNA (cfDNA) were analyzed to detect ESR1 mutations and methylation in patients with advanced breast cancer. CTC‐derived DNA showed higher sensitivity for mutation detection and revealed complementary genetic and epigenetic alterations, highlighting the added value of CTC analysis for understanding ...

A 64 × 64 CMOS digital pixel array based on pulse width analogue to digital conversion, with on chip linearising circuit

, 2004
This paper describes a 64 × 64 digital pixel array employing a pulse width analogue to digital conversion scheme. Each pixel contains a photodiode sensor, comparator and memory, and in conjunction with a central control circuit performs the analogue to ...

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

FEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Computer Aided Analysis of Turbine Blade Vibration Test Data

Measurement + Control, 1973
A pilot system has been developed which automatically scans and evaluates experimental vibration data obtained from a test rig replica of a bladed wheel of a turbine in service. High vibration amplitude signals are selected for further analysis.

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Digitizing UK analogue magnetogram records from large geomagnetic storms of the past two centuries

Geoscience Data Journal, 2023
Continuous geomagnetic records of the strength and direction of the Earth's field at the surface extend back to the 1840s. Over the past two centuries, eight observatories have existed in the United Kingdom, which measured the daily field variations ...

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Time‐interleaving design of error‐feedback sigma‐delta modulators with infinite impulse response noise transfer function

IET Circuits, Devices and Systems, 2021
Transceivers built to modern communication standards tend to be as digital as possible, including the radio‐frequency stages. This forces the digital‐to‐analogue converters (DACs) in the transmitter section to have a large bandwidth.
