TL;DR: In this paper, a review of terahertz-emission devices based on the high-temperature superconductor Bi2Sr2CaCu2O8+δ is presented.
Abstract: Layered superconductors such as the copper-oxide high-temperature superconductor Bi2Sr2CaCu2O8+δ are emerging as compact sources of coherent continuous-wave electromagnetic radiation in the subterahertz and terahertz frequency ranges. The basis of their operation is the Josephson effect, which intrinsically occurs between the superconducting layers. The Josephson effect naturally converts a direct-current voltage into a high-frequency electric current. Therefore, a unique property of the devices reviewed here is the wide tunability of their frequency by varying the bias voltage. Recently, emission powers of free-space radiation of several hundreds of microwatts and emission linewidths as low as 6 MHz at 600 GHz have been achieved. These devices are promising for new applications in imaging, medical diagnostics, spectroscopy and security. Recent progress on terahertz-emission devices based on the high-temperature superconductor Bi2Sr2CaCu2O8+δ is reviewed. The emission mechanism is explained as a result of collective resonant modes in a stack of intrinsic Josephson junctions. Remarkable features of the linewidth, tunability, the optimum bias condition and the thermal influence are discussed.

TL;DR: The results of this study raise the index of suspicion that cardiovascular risk factors and particular physical loading may contribute to DD; however additional studies are required to further investigate associations between DD and these factors.

TL;DR: Soil deposition density maps of gamma-ray emitting radioactive nuclides from the Fukushima Dai-ichi Nuclear Power Plant (NPP) accident were constructed on the basis of results from large-scale soil sampling, and the radiation doses from radioactive cesium were found to be much higher than those from the other radioactivenuclides.

TL;DR: A functional polymorphism in type I IFN pathway gene TLR7 predisposing to SLE is established, especially in Chinese and Japanese male subjects, with a stronger effect in male than female subjects.
Abstract: Systemic lupus erythematosus (SLE) is a multisystem, autoimmune disease that predominantly affects women. Previous findings that duplicated Toll-like receptor 7 (Tlr7) promotes lupus-like disease in male BXSB mice prompted us to evaluate TLR7 in human SLE. By using a candidate gene approach, we identified and replicated association of a TLR7 3′UTR SNP, rs3853839 (G/C), with SLE in 9,274 Eastern Asians (Pcombined = 6.5 × 10−10), with a stronger effect in male than female subjects [odds ratio, male vs. female = 2.33 (95% CI = 1.64–3.30) vs. 1.24 (95% CI = 1.14–1.34); P = 4.1 × 10−4]. G-allele carriers had increased TLR7 transcripts and more pronounced IFN signature than C-allele carriers; heterozygotes had 2.7-fold higher transcripts of G-allele than C-allele. These data established a functional polymorphism in type I IFN pathway gene TLR7 predisposing to SLE, especially in Chinese and Japanese male subjects.

TL;DR: An order is proposed to be created and named Picornavirales, to include viruses infecting eukaryotes that share similar properties, including a positive-sense RNA genome and capsid proteins organized in a module containing three related jelly-roll domains.
Abstract: Despite the apparent natural grouping of “picorna-like” viruses, the taxonomical significance of this putative “supergroup” was never addressed adequately. We recently proposed to the ICTV that an order should be created and named Picornavirales, to include viruses infecting eukaryotes that share similar properties: (i) a positive-sense RNA genome, usually with a 5′-bound VPg and 3′-polyadenylated, (ii) genome translation into autoproteolytically processed polyprotein(s), (iii) capsid proteins organized in a module containing three related jelly-roll domains which form small icosahedral, non-enveloped particles with a pseudo-T = 3 symmetry, and (iv) a three-domain module containing a superfamily III helicase, a (cysteine) proteinase with a chymotrypsin-like fold and an RNA-dependent RNA polymerase. According to the above criteria, the order Picornavirales includes the families Picornaviridae, Comoviridae, Dicistroviridae, Marnaviridae, Sequiviridae and the unassigned genera Cheravirus, Iflavirus and Sadwavirus. Other taxa of “picorna-like” viruses, e.g. Potyviridae, Caliciviridae, Hypoviridae, do not conform to several of the above criteria and are more remotely related: therefore they are not being proposed as members of the new order. Newly described viruses, not yet assigned to an existing taxon by ICTV, may belong to the proposed order.
