Achromatic metalens composed of arrays subwavelength nanostructures with spatially varying geometries is attractive for a number optical applications. However, the limited degree freedom in single layer achromatic metasurface design makes it difficult to simultaneously guarantee sufficient phase dispersion and high diffraction efficiency, which restricts bandwidth efficiency metalens. Here we p...

The dependences of the spectra radiation-induced attenuation (RIA) light in a pure-silica core (PSC) optical fiber (OF) during and after gamma-irradiation up to 590 kGy at dose rate 7.6 Gy/s near infrared range have been investigated. It was shown that starting with an absorbed ~100 kGy, RIA 1550 nm becomes larger than 1310 due increase long-wavelength (LWL) RIA. absorption band, maximum wavele...

The genomes of many vertebrates show a characteristic heterogeneous distribution of GC content, the so-called GC isochore structure. The origin of isochores has been explained via the mechanism of GC-biased gene conversion (gBGC). However, although the isochore structure is declining in many mammalian genomes, the heterogeneity in GC content is being reinforced in the avian genome. Despite this...

Sensing ability of caffeine interaction with Phe-Phe annotates (PNTs), is presented (Govindhan et al., 2017; Karthikeyan et al., 2014; Tavagnacco et al., 2013; Kennedy et al., 2011; Wang et al., 2017) [1-5] in this data set. Investigation of synthesized caffeine carrying peptide nanotubes are carried out by FT-Raman spectral analysis and high resolution transmission electron microscopy (HR-TEM)...

The 2WIDE SENSE (WIDE spectral band & WIDE dynamics multifunctional imaging SENSor Enabling safer car transportation) EU funded project is aimed at the development of a low-cost camera sensor for automotive applications able to acquire the full visible to Short Wave InfraRed (SWIR) spectrum, from 400 to 1700 nm. This paper presents the results obtained using this extended spectral responsivity ...

Bacteria have remarkably robust cell shape control mechanisms. For example, cell diameter only varies by a few percent across a population. MreB is necessary for establishment and maintenance of rod shape although the mechanism of shape control remains unknown. We perturbed MreB in two complimentary ways to produce steady-state cell diameters over a wide range, from 790±30 nm to 1700±20 nm. To ...

In the analysis of finished pharmaceutical products, numerous innovative analytical techniques are often used, i.e., Raman spectroscopy, scanning electron microscopy, computer microtomography, directional hemispherical reflectance, and hyperspectral analyses. These allow for identification changes in solid phases. Many advantages over other can be attributed to these techniques, e.g., they rapi...

High-power supercontinuum spanning over more than an octave was generated using a high power femtosecond fiber laser amplifier and a multicore nonlinear photonic crystal fiber (PCF). Long multicore PCFs (as long as 20 m in our experiments) are shown to enable supercontinuum generation in an isolated fundamental supermode, with the manifold of other PCF modes suppressed due to the strong evanesc...
