Amblyopia is a developmental disorder of the visual cortex that is often accompanied by strong suppression of one eye. We present a new technique for measuring and treating interocular suppression in patients with amblyopia that can be deployed using virtual reality goggles or a portable iPod Touch device.

The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda: 15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5 Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

We describe an experiment designed to probe the electronic damage induced in nanocrystals of Buckminsterfullerene (C60) by intense, femtosecond pulses of X-rays. The experiment found that, surprisingly, rather than being stochastic, the X-ray induced electron dynamics in C60 are highly correlated, extending over hundreds of unit cells within the crystals1.

Human In Vitro Suppression as Screening Tool for the Recognition of an Early State of Immune Imbalance

Tregs are potent suppressors of the immune system. There is a lack of unique surface markers to define them, hence, definitions of Tregs are primarily functional. Here we describe an optimized in vitro assay capable of identifying immune imbalance in subjects at risk to develop T1D.

¹H NMR: Long-Range Coupling

The coupling interactions of nuclei across four or more bonds are usually weak, with J values less than 1 Hz. While these are usually not observed in spectra, the presence of multiple bonds along the coupling pathway can result in observable long-range coupling. In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene π orbitals.
FAQs
Parasitic inductance and capacitance can form an underdamped resonant network when a circuit experiences rapid switching or an abrupt signal change. Because the network is insufficiently damped, voltage or current moves beyond the intended waveform and oscillates around it. The transient therefore reflects both the circuit’s parasitic elements and the speed of the signal change.
Added damping reduces the energy exchange that sustains oscillation, allowing the transient to settle closer to its intended value. In practice, engineers may introduce a resistor-capacitor snubber or series resistance, but stronger damping is not free: it can slow switching and increase power loss. The design target is a compromise between waveform cleanliness and circuit efficiency.
A resistor-capacitor snubber and series resistance add damping directly, whereas filtering, improved grounding, and transmission-line termination address unwanted behavior through other circuit features. The choice is not simply about maximum attenuation: each approach must be judged against switching speed, power loss, electromagnetic interference, signal distortion, component stress, and false triggering.
Suppressing the transient can reduce electromagnetic interference, signal distortion, component stress, and false triggering. Those outcomes matter because ringing is not merely a visual imperfection: it can disturb nearby circuitry, impose unwanted electrical stress, or make a circuit respond incorrectly. Evaluating suppression therefore includes both waveform quality and reliable system behavior.
Begin by relating the unwanted oscillation to the rapid switching or abrupt signal condition that excites it, then consider whether the likely control point is the switching path, signal path, grounding arrangement, or transmission line. Candidate measures include an RC snubber, series resistance, filtering, improved grounding, or termination. Finally, compare ringing reduction with switching speed and power loss.
It is particularly relevant in power converters, digital circuits, and high-speed instrumentation, where rapid signal transitions make unwanted transients consequential. In power conversion, suppression can limit component stress; in digital systems, it can reduce false triggering; and in instrumentation, it can preserve waveform fidelity. Across these settings, the goal is more reliable operation with fewer interference-related problems.
