background: this study was done to determine the prevalence of publication misconduct among iranian authors. methods: data were collected through an email survey of corresponding authors of papers published in iranian journals indexed in scopus during 2009-2011. using the double list experiment, these individuals were indirectly questioned about committing one of the five misconducts including ...

Here we describe biosensors that provide readouts for protein stability in the cytosolic compartment of prokaryotes. These biosensors consist of tripartite sandwich fusions that link the in vitro stability or aggregation susceptibility of guest proteins to the in vivo resistance of host cells to the antibiotics kanamycin, spectinomycin, and nourseothricin. These selectable markers confer antibi...

A solid powder of hydrogen bonded dimers of a tetraurea calix[4]arene is able to exchange the encapsulated guest in contact with the vapor of a second guest. The molecules of a guest-free powder obtained from a polar solvent cannot rearrange in the solid phase to form new guest-filled capsules under these conditions.

As systems provide increasing memory capacities to support memory-intensive workloads, Translation Lookaside Buffers (TLBs) are becoming a critical performance bottleneck. TLB performance is exacerbated with virtualization, which is typically implemented with two-dimensional nested page tables. While virtualization vendors recommend using large pages to mitigate TLB overheads, in practice, page...

The registration of guests who attend weddings often encounters a number problems. Starting from crowded queue at certain hours or invited whose writings are difficult to read. Physical books record wedding can only be kept by one party. These problems certainly overcome designing Web-Based Wedding Guest Book System Design. is designed with MySQL database system and uses PHP programming languag...

The effect of the mechanical deformation of metal-organic frameworks on guest diffusion was investigated by employing molecular dynamics simulations. Two basic deformation modes, uniaxial tensile and shear deformation, were considered. The computed shear modulus of the zeolitic imidazolate framework-8 (ZIF-8) model system was much lower than the Young's modulus, which is in agreement with the e...

Mesoporous silica materials are ideally suited as host–guest systems in nanoscience with applications ranging frommolecular sieves, catalysts, nanosensors to drug-delivery-systems. For all these applications a thorough understanding of the interactions between the mesoporous host system and the guest molecules is vital. Here, we investigate these interactions using single molecule spectroscopy ...

Density functional theory (DFT) calculations with dispersion corrections elucidated the key factors for determining the arrangement of π-conjugated oligomers inside a carbon nanotube. The current study considered methyl-terminated terfurans as guests inside a host tube; the results were compared with those obtained in previous studies for methyl-terminated terthiophenes inside a nanotube. DFT c...
