Several problems arising in control system analysis and design, such as reduced order controller synthesis, involve minimizing the rank of a matrix variable subject to linear matrix inequality (LMI) constraints. Except in some special cases, solving this rank minimization problem (globally) is very difficult. One simple and surprisingly effective heuristic, applicable when the matrix variable i...

Context. Studies of Class 0 objects allow to characterize the dynamical processes taking place at onset star formation process and determine physical mechanisms responsible for outcome collapse. Observations dense gas tracers characterization key kinematics that are directly involved in process, such as infall, outflow, rotation. Aims. This work is aimed investigating molecular line velocity pr...

this paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. for this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. the research method for...

background: dengue is a global arboviral threat to humans; causing 390 million infections per year. the availability of safe and effective tetravalent dengue vaccine is a global requirement to prevent epidemics, morbidity, and mortality associated with it. methods: five experimental groups (6 mice per group) each of 5-week-old balb/c mice were immunized with vaccine and placebo (empty plasmid) ...

We have imaged the circumstellar envelope around the binary protostar L1551 IRS 5 in CS (J=7–6) and 343 GHz continuum emission at ∼ 3 resolution using the Submillimeter Array. The continuum emission shows an elongated structure (∼ 220× 100 AU) around the binary perpendicular to the axis of the associated radio jet. The CS emission extends over ∼ 400 AU, appears approximately circularly symmetri...

The viral membrane proteins M and E are the minimal requirements for the budding of coronavirus particles. Since the E protein occurs in particles only in trace amounts, the lateral interactions between the M proteins apparently generate the major driving force for envelope formation. By using coimmunoprecipitation and envelope incorporation assays, we provide extensive evidence for the existen...

objective(s): production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. the goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. materials and methods: multiple amino acid sequences of different i...
