DNS is a critical infrastructure of the global Internet. To assure DNS’s efficient and robust operations, each domain, especially each of the Top-Level-Domains (TLDs), should deploy multiple redundant nameservers in diverse locations. To assess the robustness of TLD nameserver deployment regarding the nameserver redundancy and location diversity, we conduct a measurement study by sending specia...

BACKGROUND The narrative abilities provide valuable information about the linguistic, cognitive and social development of school-age children with typical language development (TLD). AIM To examine the temporal ordering of figures and the narrative abilities of school-age children with TLD in relation to the type of discourse presented. METHOD Participants of this study included 60 children...

Microstrip fed inset patch antennas embedded in planar and cylindrically curved surfaces are introduced to be used in Body Area Networks (BANs) presented. These antennas are designed as wearable antennas for industrial, scientific and medical (ISM) band wireless communication networking. The proposed antennas consist of 50 Ω microstrip line feeding inset patch printed on the front face of diele...

The goal of this paper is to construct discretizations for the equations of Lagrangian gas dynamics that preserve plane, cylindrical, and spherical symmetry in the solution of the original differential equations. The new method uses a curvilinear grid that is reconstructed from a given logically rectangular distribution of nodes. The sides of the cells of the reconstructed grid can be segments ...

Carbon nanotubes are composed of cylindrical graphite sheets. Both nanotubes and graphite sheets are benzenoid derivatives composed of sp2 carbon atoms arranged in a hexagonal pattern. Therefore both systems are aromatic. The extent of the aromatic character of a molecule G (here benzenoids) can be explained in terms of the number of possible Kekulé structures in G. In this work the Kekulé stru...

Dorsal cell fate in Drosophila embryos is specified by an activity gradient of Decapentaplegic (Dpp), a homologue of bone morphogenetic proteins (Bmps) 2/4. Previous genetic and biochemical studies have revealed that the Sog, Tsg and Tld proteins modify Dpp activity at the post-transcriptional level. The predominant view is that Sog and Tsg form a strong ternary complex with Dpp that prevents i...

BACKGROUND Industrial radiography is known to be one of the most vulnerable lines of work among the range of different radiation work. According to the relevant law in Korea, every worker registered in this work should check their blood cell counts every year in addition to their thermoluminescent dosimeter (TLD) doses. Since the law was enacted, however, few follow-up studies have been carried...

We present measurements of the thermal resistivity ρ(t,L) (t ≡ T/Tλ − 1) near the superfluid transition temperature Tλ of 4He at saturated vapor pressure and confined in glass capillary arrays with rectangular capillary crosssections of spacing L = 1 μm, width w = 10μm, and length d # 1 mm. We expect the finite-size effect in this rectangular geometry to provide a good approximation to that in ...

The efficient reduction of the pulse length and the energy width of electron beams plays a crucial role in the generation of short pulses in the range of sub-picoseconds at future light sources. At the radiation source ELBE in DresdenRossendorf short pulses are required for coherent THz generation and laser-electron beam interaction experiments such as X-ray Thomson scattering. Energy dechirpin...

Drosophila metalloproteinase Tolloid (TLD) is responsible for cleaving the antagonist Short gastrulation (SOG), thereby regulating signaling by the bone morphogenetic protein (BMP) Decapentaplegic (DPP). In mice there are four TLD-related proteinases, two of which, BMP1 and mammalian Tolloid-like 1 (mTLL1), are responsible for cleaving the SOG orthologue Chordin, thereby regulating signaling by...
