considering a) a) that a number of SCPC (Single Channel Per Carrier) carriers are transmitted via a single satellite transponder in satellite communication systems; b) that, for efficient use of satellite power, the transponder would be operated in the near saturation region, in which case intermodulation noise affects signal quality; c) that the intermodulation products falling into the freque...

The paper presents an application of satellite communication dedicated to medical assistance of people living in hazardous social-environmental conditions. This objective has been fulfilled by a consortium between telecommunication firms and public research bodies, in co-operation with the Italian Defense Staff, by means of a telemedicine network, involving hospitals in Sarajevo, Bosnia and Her...

Typically, unsupervised segmentation of speech into the phone- and word-like units are treated as separate tasks often done via different methods which do not fully leverage inter-dependence two tasks. Here, we unify them propose a technique that can jointly perform both, showing these indeed benefit from each other. Recent attempts employ self-supervised learning, such contrastive predictive c...

The cyanobacterial small CAB-like proteins (SCPs) consist of one-helix proteins that resemble transmembrane regions of the light-harvesting proteins of plants. To determine whether these proteins are associated with protein complexes in the thylakoid membrane, an abundant member of the SCP family, ScpD, was marked with a His tag, and proteins co-isolating with His-tagged ScpD were identified. T...

Group A streptococcus (GAS) causes variety of diseases ranging from common pharyngitis to life-threatening severe invasive diseases, including necrotizing fasciitis and streptococcal toxic shock-like syndrome. The characteristic of invasive GAS infections has been thought to attribute to genetic changes in bacteria, however, no clear evidence has shown due to lack of an intriguingly study using...

in scpc-dama satellite networks, the baseband rrc pulse shaping is utilized to reduce the bandwidth and inter symbol interference (isi). but the variation in carrier's envelope, which expands the spectrum and ultimately increases the bandwidth, causes isi and quadrature channel crosstalk (qcc). the goal of this paper is to introduce a method to shape baseband rrc pulses, in order to make a near...

DOI: 10.1002/aenm.201301329 Energy conversion and storage, [ 1–3 ] as the two most important technologies for energy, are usually two distinct processes that are performed by using two different and separated physical units, such as a piezoelectric nanogenerator and lithium-ion battery. [ 4–9 ] Recently, we presented a novel fundamental mechanism that directly hybridizes the two processes into ...

Interleukin-8 (IL-8) promotes neutrophil-mediated host defense through its chemoattractant and immunostimulatory activities. The Group A Streptococcus (GAS) protease SpyCEP (also called ScpC) cleaves IL-8, and SpyCEP expression is strongly upregulated in vivo in the M1T1 GAS strains associated with life-threatening systemic disease including necrotizing fasciitis. Coupling allelic replacement w...
