We have demonstrated simple reconfigurable all-optical logic operations based on four-wave mixing in semiconductor optical amplifier and encoding information the polarization of input signals. Experimental implementation six functions (including XOR, XNOR, AND, NOR, etc.) operating at 10 Gb/s were realized by simply adjusting two controllers setup.
Boron-doped carbon coated Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> is prepared, and different impacts of various carbon–boron species on the improvement electrochemical performance for sodium lithium ion batteries are analyzed discussed in this work.
The global invasion of Tephritidae (fruit flies) attracts a great deal attention in the field plant quarantine and biology because their economic importance. Predicting which one hundreds potential invasive fruit fly species is most likely to establish region presents significant challenge, but can be facilitated using self organising map (SOM), able analyse associations rank large numbers simultaneously with an index establishment. A presence/absence dataset including 180 economically 118...
Colorimetric detection of biogenic amines, well-known indicators food spoilage, plays an important role for monitoring safety. However, common colorimetric sensors amines suffer from low color resolution or complicated design and intricate output the end-users. Herein, we explored a simple but effective strategy visual with multiple change based on hydrolysis-induced silver metallization reaction to tune localized surface plasmon resonance (LSPR) adsorption Au nanorods (NRs). The blue shift...
Abstract The second largest Phanerozoic mass extinction occurred at the Ordovician-Silurian (O-S) boundary. However, unlike other major events, driver for O-S remains uncertain. abundance of mercury (Hg) and total organic carbon (TOC) Ordovician early Silurian marine sediments were analyzed from four sections (Huanghuachang, Chenjiahe, Wangjiawan Dingjiapo) in Yichang area, South China, as a test evidence massive volcanism associated with event. Our results indicate Hg concentrations...
The skins of frogs the genus Rana synthesize a complex array antimicrobial peptides that may be grouped into eight families on basis structural similarity. A total 24 with differential growth‐inhibitory activity towards Gram‐positive bacterium Staphylococcus aureus, Gram‐negative Escherichia coli and yeast Candida albicans were isolated from extracts three closely related North American frogs, luteiventris (spotted frog), berlandieri (Rio Grande leopard frog) pipiens (Northern frog)....
Green-photoluminescent phenyl-doped graphitic carbon nitride (PDCN) powders were prepared and applied for the visualization of latent fingerprints.
The 2-μm wave band is emerging as a potential new window for optical telecommunications with several distinct advantages over the traditional 1.55 μm region. First of all, hollow-core photonic gap fiber (HC-PBGF) an transmission candidate ultra-low nonlinearity and lowest latency (0.3% slower than light propagating in vacuum) that has its minimum loss within wavelength band. Second, thulium-doped amplifier operates this spectral region provides significantly more bandwidth erbium-doped...
Colorado Potato Beetle (CPB) is a devastating invasive pest of potato both in its native North America and now across Eurasia. It also damages eggplant, tomato feeds on several wild species the Solanaceae, such as S. eleagnifolium rostratum Dunal (SR). Since first categorized 1864, CPB has spread rapidly America, Europe Asia. In light invasiveness economic importance, it necessary to study how climate change host availability may alter distribution CPB. Maximum Entropy (MaxEnt) models were...
An 80 W 350-2400 nm monolithic supercontinuum (SC) source is reported. The high-power SC generated in a uniform multi-core photonic crystal fiber (PCF) pumped by 1016 pulsed laser. specially designed PCF has seven 4.5 μm diameter cores, 0.85 air-filling fraction, and zero dispersion wavelength (ZDW) of 991 nm. laser delivers up to 114 average power, which believed be the highest currently reported for picosecond lasers working below 1020 In order ensure robust compact all-fiber structure,...
Abstract Facial palsy (FP) profoundly influences interpersonal communication and emotional expression, necessitating precise diagnostic monitoring tools for optimal care. However, current electromyography (EMG) systems are limited by their bulky nature, complex setups, dependence on skilled technicians. Here we report an innovative biosensing approach that utilizes a PEDOT:PSS-modified flexible microneedle electrode array (P-FMNEA) to overcome the limitations of existing EMG devices. Supple...
In this work, we demonstrate a watt-level laser producing high-order, petal-shaped output modes with tunable topological charge, by using an axicon-based divergent annular pump beam. The charge of the beam could be varied in range 34–72 adjusting position Nd:YVO4 crystal relative to focal plane highest order petal-mode generated from system had 72 and power 1.3 W. up 2.1 W 34 was achieved at absorbed 5.8 were observed robust under scaling on propagation, same spatial profiles being...

We present methods and processes of using a ghost-peak-free distributed polarization crosstalk analyzer (DPXA) to accurately obtain all related parameters polarization-maintaining (PM) fibers. show that by first inducing series equidistant periodic peaks along PM fiber then measuring the positions widths these analyzer, birefringence fiber, including group birefringence, variation dispersion, temperature coefficient, can be obtained. further DPXA has ability identify eliminate contributions...
Bactrocera dorsalis, the Oriental fruit fly, is one of world's most destructive agricultural insect pests and a major impediment to international fresh commodity trade. The genetic structuring species across its entire geographic range has never been undertaken, because under former taxonomy B. dorsalis was divided into four distinct taxonomic entities, each with their own, largely non-overlapping, distributions. Based on extensive sampling six priori groups from 63 locations, geometric...
We investigate the operation of holmium-doped fibre amplifiers (HDFAs) in 2.1 µm spectral region.For first time we demonstrate a diode-pumped HDFA.This amplifier provides peak gain 25 dB at 2040 nm with 15 window spanning wavelength range 2030 -2100 an external noise figure (NF) 4-6 dB.We also compare HDFAs when pumped 1950 and 2008 nm.The HDFA 41 2060 2050 -2120 NF 7-10 dB.By pumping longer bandwidth is shifted to wavelengths using this architecture was demonstrated 39 2090 -2150 over 8-14...
