The Greek letter lambdaλrepresents wavelength, expressed in meters. Thevis wave velocity, calculated as meters per second (m/s). And thefstands for frequency, which is measured in hertz (Hz). For example, iffis the frequency of the signal as measured in megahertz (MHz), andλis the wav...
Sexual behavior is essential for the survival of many species. In female rodents, mate preference and copulatory behavior depend on pheromones and are synchronized with ovulation to ensure reproductive success. The neural circuits driving this orchestration in the brain have, however, remained elusive. ...
Mesencephalic astrocyte-derived neurotrophic factor (MANF) has cytoprotective effects on various injuries, including cerebral ischemia, and it can promote recovery even when delivered intracranially several days after ischemic stroke. In the uninjured ro
Methods We selected 4 wavelength types, and each HI was measured and calculated (410 nm/HI-1, 451 nm/HI-2, 545 nm/HI-3, and 571 nm/HI-4). To compare the 4 HI types, we investigated the influence of 3 interference components using artificially hemolyzed specimens (AHSs). We also ...

Also, long-wavelength ultra low-temperature illumination and hole-burning experiments, leading to charge separation in PSII [37], [38] were taken as evidence that a low-energy state in the CP47 in PSII was close to the RC and thus could not be dominated by Chl 627(29). In isolated CP...
The wavelength for n=3 to n=2 transition of the hydrogen atom is 656.3 nm. What are the wavelength for this same transition in (a) positronium, which consists of an electron and a positron (b) singly ionized helium View Solution
In-flight performance of the MAMA detectors on the Space Telescope Imaging Spectrograph The Space Telescope Imaging Spectrograph (STIS) is a versatile HST instrument covering the 115 - 1000 nm wavelength range in a variety of spectroscopic and imaging modes. Coverage of the ultraviolet range (115 ...
Resistance artery vasodilation in response to hypoxia is essential for matching tissue oxygen and demand. In hypoxia, erythrocytic hemoglobin tetramers produce nitric oxide through nitrite reduction. We hypothesized that the alpha subunit of hemoglobin e
The fluorescence of fura2 was excited alternatively at wavelengths of 340 and 380 nm by means of a high-speed wavelength-switching device (Multistream Pro with NI USB-60001, Cairn, UK). Stabilised OptoLED power supply was used for controlled illumination and modulation of two-channel light-...
