In order to provide negotiated QoS to the end users in next generation mobile networks, a traffic conditioner may be deployed to provide conformance of a service agreement. The traffic conditioning is performed by traffic shaping or/and policing. A framework of applying traffic conditioning in radio access network is proposed in this paper. The main idea of our traffic conditioning approach is ...

Most secretory and membrane proteins are sorted by signal sequences to the endoplasmic reticulum (ER) membrane early during their synthesis. Targeting of the ribosome-nascent chain complex (RNC) involves the binding of the signal sequence to the signal recognition particle (SRP), followed by an interaction of ribosome-bound SRP with the SRP receptor. However, ribosomes can also independently bi...

A series of mixed Cp* amidate tantalum complexes Cp*Ta(RNC(O)R')X(3) (where R = Me(2)C(6)H(3), (i)Pr, R' = (t)Bu, Ph, X = Cl, Me) have been prepared via salt metathesis and their fundamental reactivities under reducing conditions have been explored. Reaction of the tantalum chloro precursors with potassium graphite under N(2) or Ar leads to the stereoselective formation of the terminal tantalum...

Unconventional mRNA splicing on the endoplasmic reticulum (ER) membrane is the sole conserved mechanism in eukaryotes to transmit information regarding misfolded protein accumulation to the nucleus to activate the stress response. In metazoans, the unspliced form of X-box-binding protein 1 (XBP1u) mRNA is recruited to membranes as a ribosome nascent chain (RNC) complex for efficient splicing. W...

An undirected edge-weighted graph can have at most n2 edge connectivity cuts. A succinct and algorithmically useful representation for this set of cuts was given by [4], and an e cient sequential algorithm for obtaining it was given by [12]. In this paper, we present a fast parallel algorithm for obtaining this representation; our algorithm is an RNC algorithm in case the weights are given in u...

In all three kingdoms of life, co-translational targeting of secretory and membrane proteins to the prokaryotic plasma membrane or eukaryotic endoplasmic reticulum is mediated by a ribonucleoprotein complex, the signal recognition particle (SRP), and its membrane-associated receptor (SR). SRP binds to signal sequences of nascent proteins as they emerge from the exit tunnel of the ribosome. The ...
