The production of K * (892) 0 and φ(1020) mesons has been measured in p–Pb collisions at √ s NN = 5.02 TeV. K * 0 and φ are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range −0.5 < y < 0. The transverse momentum spectra, measured as a function of the multiplicity, have a p T range from 0 to 15 GeV/c for K * 0 and from 0.3 to 21 GeV/c for φ. Integra...
Ultrathin metal coordination Prussian blue (PB) nanoribbons with tunable width have been successfully synthesized. The morphology and microstructure of PB nanoribbons are characterized using UV-vis, FT-IR, AFM, TEM and XRD. PB nanoribbons synthesized possess an ultrathin thickness of approximately 1 nm and narrow width. The width of PB ribbons can be tuned by varying the chain length of polymer...
In most of the models of hadronic collisions the number of exchanged colour strings grows with energy and atomic numbers of the projectile and target. At high string densities interaction between them becomes important, which should melt them into the quark-gluon plasma state in the end. It is shown that under certain reasonable assumptions about the the string interaction, a phase transition t...
Aryl hydrocarbon receptor (Ahr), a transcription factor, plays a critical role in autoimmune inflammation of the intestine. In addition, microRNAs (miRNAs), small non-coding oligonucleotides, mediate pathogenesis of inflammatory bowel diseases (IBD). However, the precise mechanism and interactions of these molecules in IBD pathogenesis have not yet been investigated. We analyzed the role of Ahr...
In order to reduce the architectural complexity of broadband networks, the sharing of information among network management and control mechanisms is investigated. We introduce a concept for sharing dynamic information in real-time that identifies the current changes in the network state as a global pool of network events called the event base. Network mechanisms share events by asynchronously i...
The design and measurements of a 200 GHz downconverter in 90 nm standard CMOS are presented. A positive conversion gain of +6.6 dB, a noise figure of 29.9 dB and an output bandwidth of 3 GHz are measured for an LO power of −14.9 dBm. The conversion gain remains within 3 dB for an RF frequency between 186 and 212 GHz. Downconversion of BPSK and QPSK signals is demonstrated with eye diagrams and ...
HH 212 is a highly collimated jet discovered in H2 powered by a young Class 0 source, IRAS 054130104, in the L1630 cloud of Orion. We have mapped around it in 1.33 mm continuum, CO (J = 2−1), CO (J = 2 − 1), CO (J = 2 − 1), and SO (JK = 65 − 54) emission at ∼ 2.5 ′′ resolution with the Submillimeter Array. A dust core is seen in the continuum around the source. A flattened envelope is seen in C...
Factor in the germline alpha (FIGLA) is an oocyte-specific basic helix-loop-helix transcription factor essential for primordial follicle formation and expression of many genes required for folliculogenesis, fertilization and early embryonic survival. Here we report the characterization of bovine FIGLA gene and its regulation during early embryogenesis. Bovine FIGLA mRNA expression is restricted...
The investigation of respiratory infections by molecular techniques provides important information about the epidemiology of respiratory disease, especially during the post-vaccination era. The objective of the present study was the detection of bacterial pathogens directly in clinical samples from patients with upper and lower respiratory tract infections using multiplex polymerase chain react...
BACKGROUND We hypothesized that chronic inhibition of epidermal growth factor receptor (EGFR) by cetuximab, a monoclonal anti-EGFR antibody, induces up-regulation of its ligands resulting in resistance and that microRNAs (miRs) play an important role in the ligand regulation in head and neck squamous cell carcinoma (HNSCC). METHODOLOGY/PRINCIPAL FINDINGS Genome-wide changes in gene and miR ex...
