The Structural and Biochemical Database (SBD), developed as part of the US NSF-funded Assembling the Fungal Tree of Life (AFTOL), is a multi-investigator project. It is a major resource to present and manage morphological and biochemical information on Fungi and serves as a phyloinformatics tool for the scientific community. It also is an important resource for teaching mycology. The database, ...

Abstract Since the invention of laser in 60s, one most fundamental communication channels has been free-space optical channel. For this type channel, a number effects generally need to be considered, including diffraction, refraction, atmospheric extinction, pointing errors and, importantly, turbulence. Because all these adverse features, (FSO) channel is more difficult study than stable fiber-...

Recently, wireless communications started incorporating FSO systems to a large extent due their high bandwidth and the low installation operational cost. However, performance deteriora...

The utilization of drones as flying base stations (BSs) in the sixth-generation (6G) cellular networks has attracted much attention recently. In this context, free-space optical (FSO) systems could be deployed to provide high-capacity fronthaul/backhaul links between and ground BSs. Particularly, a drone-to-ground FSO communication link can established by equipping drone with modulating retro-r...

The role of alpha 2-adrenoceptors on vascular sympathetic nerve endings in modulating release of the sympathetic neurotransmitter norepinephrine (NE) in humans was examined by measuring the regional rate of appearance of NE in forearm venous plasma (forearm NE spillover [FSO]) in 32 healthy volunteers during intra-arterial infusion of drugs acting at adrenoceptors or directly on vascular smooth...

As existing technologies are refined and novel microbial inactivation technologies are developed, there is a growing need for a metric that can be used to judge equivalent levels of hazard control stringency to ensure food safety of commercially sterile foods. A food safety objective (FSO) is an output-oriented metric that designates the maximum level of a hazard (e.g., the pathogenic microorg...

Free Space Optical (FSO) communication is a very recent and emerging technology to establish broadband wireless data transmission system using modulated optical beams. The adoption of FSO system is mainly needed when any physical connection between the transmitter and receiver is practically impossible and where high bandwidth data transmission is expected. The performance of FSO communication ...

PURPOSE Cancer is one of the leading causes of mortality worldwide. Tumor cells circulating in the blood evidence the migration of tumor from the site of origin to another site leading to the formation of new metastatic lesion and establishment of metastatic tumors. In the present study, cultured metastatic tumor cells were injected into the C57BL/6 mice through tail-vein injection (TVI) and th...
