Some of the problems experienced by users of hearing aids (HAs) when listening to music are relevant to cochlear implants (CIs). One problem is related to the high peak levels (up to 120 dB SPL) that occur in live music. Some HAs and CIs overload at such levels, because of the limited dynamic range of the microphones…

[_page_10_Figure_10.jpeg]: Quantitative validation of the dynamic range extension. (a) Quantitative sample construction. We cover an LED lamp with an ND filter with a 0.4 and 4 OD range. The red line indicates the intensity profile plotted in (c). (b) An LDR image of the sample was taken by a Canon 5D Mark II using a…

While shortwave infrared (SWIR) imaging provides superior tissue penetration and reduced autofluorescence for preclinical applications, quantitative fluorescence analysis is hindered by the limited dynamic range of InGaAs cameras, forcing a focus on either bright or dim anatomical features. We develop a high dynamic…

'Gregor Schewior'] Advanced driver assistance systems (ADAS) relying on multiple cameras are increasingly prevalent in vehicle technology. Yet, conventional imaging sensors struggle to capture clear images in conditions with intense illumination contrast, such as tunnel exits, due to their limited dynamic range.…

The dynamic range of contrast-encoding in the early visual system has been investigated at both single-neuron and population levels in animals using oriented stimuli such as gratings and Gabor patches. However, contrast-encoding of unoriented stimuli such as Gaussians has been less explored, even though such stimuli…

Improvements in the dynamic range and sensitivity of digital MEMS microphones are essential in applications like advanced noise canceling and voice recognition. A cost effective solution to achieve these goals is the companding ADC architecture. Companding ADCs split the dynamic range in several segments with different…

Precise control of gene expression in a cell-state-specific manner is essential for effective therapeutic interventions in complex and dynamic disease microenvironments. Traditional targeting strategies that rely on surface markers or cell type-specific promoters often assume static cellular identities, limiting…

The ability to modulate gene expression is crucial for studying gene function and programming cell behaviors. Combining the reliability of CRISPRi and the precision of optogenetics, the opto-CRISPRi technique is emerging as an advanced tool for live-cell gene regulation. Since previous versions of opto-CRISPRi often…

Precision medicine requires highly scalable methods of multiplexed biomarker quantification that can accurately describe patient physiology. Unfortunately, contemporary molecular detection methods are generally limited to a dynamic range of sensitivity spanning just 3–4 orders of magnitude, whereas the actual…

- Keywords: Image Segmentation, Otsu Threshold, Multi-Exposure, High Dynamic Range, Low Dynamic Range, Deep Learning. - Abstract: Regular cameras and cell phones are able to capture limited luminosity. Thus, in terms of quality, most of the produced images from such devices are not similar to the real world. They are…

Orbitrap (OT) -based mass spectrometer platforms are a gold standard in high-resolution mass spectrometry, where their primary disadvantage is slower-scanning speed in comparison to time-of-flight or linear ion trap mass analyzers. In this study, we utilize long OT transients to extend the precursor dynamic range by…

'Harvey Dillon'] Remote microphones (RMs) enable clearer reception of speech than would be normally achievable when relying on the acoustic sound field at the listener's ear (Hawkins, J Sp Hear Disord 49, 409-418, 1984). They are used in a wide range of environments, with one example being for children in educational…

We simulated the effect of several automatic gain control (AGC) and AGC-like systems and head movement on the output levels, and resulting interaural level differences (ILDs) produced by bilateral cochlear-implant (CI) processors. The simulated AGC systems included unlinked AGCs with a range of parameter settings…

The integrated radar and jamming (IRAJ) system provides a promising solution that meets the demands for miniaturization, integration, and multifunctionality in complex warfare environments. However, traditional electronic-domain IRAJ systems face limitations in operating frequency and bandwidth. In this paper, we…

'Kirsten C. Wagener' 'Volker Kuehnel' 'Kai Siedenburg'] Hearing aids have traditionally been designed to facilitate speech perception. With regards to music perception, previous work indicates that hearing aid users frequently complain about music sound quality. Yet, the effects of hearing aid amplification on musical…

1## Introduction Objective acoustic methods are widely used in voice diagnostics to assess voice disorders (Roy et al. ). This assessment method is influenced by a range of factors that must be carefully considered, including minimum hardware specifications, algorithmic variations across software, room acoustics, the…

The canonical range resolution limit in radar, sonar, and lidar systems is found to be a special case of a more general resolution limit. The general limit indicates that it is possible to surpass the canonical limit in moderate (of order unity) signal-to-noise ratio (SNR) environments by using the signal amplitude and…

We propose a new mechanism for dynamic nuclear polarization that is different from the well-known Overhauser effect, solid effect, cross effect and thermal mixing processes. In particular, we discovered that the evolution of the density matrix with the simple Hamiltonian of a coupled electron-nuclear spin pair with…

This work describes a competing activation network, which is regulated by chemical feedback at the liquid-surface interface. Feedback loops dynamically tune the concentration of chemical components in living systems, thereby controlling regulatory processes in neural, genetic, and metabolic networks. Advances in…

There are diverse engineering applications of the rapid and accurate detection of the onset of a frequency component hidden within a wideband signal. A change in the spectrum of a stator current of an induction motor [1] which is about to fail; time-frequency analysis of mechanical systems to detect faults [2]…

Electrochemical impedance spectroscopy (EIS) is one of the most widely deployed methods to characterise electrochemical systems such as batteries, fuel cells or electrolyzers. The distribution of relaxation times (DRT) represents a technique to simplify EIS data by deconvolution with a suitable kernel, while with…

Organic light-emitting diodes (OLEDs) are a revolutionary self-emitting display technology that has been successfully commercialized in mobile phones and TVs. The injected charges form both singlet and triplet excitons, and for high efficiency it is important to enable dark triplets to emit light. Currently materials…
