We reveal experimentally waveguiding characteristics and group-velocity dispersion of line defects in photonic crystal slabs as a function defect widths. The have modes with two types cutoff within the band gap. Interference measurements show that they exhibit extraordinarily large group dispersion, we found whose traveling speed is 2 orders magnitude slower than air. These can be tuned by controlling width, results agree well theoretical calculations, indicating design light paths...
Abstract An unprecedentedly large ensemble of climate simulations with a 60-km atmospheric general circulation model and dynamical downscaling 20-km regional has been performed to obtain probabilistic future projections low-frequency local-scale events. The the latter half twentieth century, 4 K warmer than preindustrial climate, century without historical trends associated anthropogenic effect are each simulated for more 5,000 years. From simulations, changes in extreme events available...
Abstract CRISPR-based nucleic-acid detection is an emerging technology for molecular diagnostics. However, these methods generally require several hours and could cause amplification errors, due to the pre-amplification of target nucleic acids enhance sensitivity. Here, we developed a platform that allows “CRI S PR-based mplifica t i o n-free digital R NA detect on (SATORI)”, by combining CRISPR-Cas13-based RNA microchamber-array technologies. SATORI detected single-stranded targets with...
We experimentally demonstrate the structural tuning of waveguiding modes line defects in photonic crystal (PC) slabs. By defect widths, we realized efficient single-mode waveguides that operate within band gap frequencies silicon-on-insulator PC The observed characteristics agree very well with three-dimensional finite difference time-domain calculations. also directly measured propagation loss and obtained a value 6 dB/mm.
A low temperature plasma deposition method using a raw material supply by sputtering has been developed. microwave electron cyclotron resonance technique was used for highly ionized generation and stream extraction at gas pressures of 10 -3 to -1 Pa. Gas molecules, particles sputtered ions in the are transported specimen substrate with an energy 30 eV. Fully oxidized, dense high quality films tantalum oxide aluminum were obtained room temperature.
Single-molecule enzyme activity-based profiling (SEAP) is a methodology to globally analyze protein functions in living samples at the single-molecule level. It has been previously applied detect functional alterations phosphatases and glycosidases. Here, we expand potential for biomarker discovery by developing semi-automated synthesis platform fluorogenic probes that can various peptidases protease activities The peptidase/protease were prepared on basis of 7-amino-4-methylcoumarin...
It is demonstrated experimentally that a single missing-hole line defect photonic crystal waveguide fabricated on silicon-on-insulator substrate can support waveguiding mode within the bandgap if width properly tuned.
Reactive ion stream etching has been developed for highly accurate with little bombardment induced damage by utilizing an electron cyclotron resonance (ECR) plasma. The energy during is controlled the interaction between ECR plasma and a divergent magnetic field, in low range from 20 to 50 eV at gas pressures of 10−2 Pa. Highly submicron patterns polysilicon molybdenum were obtained high selectivities SiO2, larger than 30, using Cl2 as main gas.

We describe two unprecedented large (100-member), long-term (61-year) ensembles based on MRI-AGCM3.2, which were driven by historical and non-warming climate forcing. These comprise the "Database for Policy Decision making Future change (d4PDF)". compare these to another model, as well observed data, investigate influence of anthropogenic activities changes in numbers record-breaking events, including: annual coldest daily minimum temperature (TNn), warmest maximum (TXx) most intense...
Magnetron mode sputtering was applied to an electron cyclotron resonance (ECR) plasma deposition technique as a material supply at low gas pressures of 10−2 Pa. Fully reacted metallic‐compound films were deposited temperatures with much higher rates than those obtained in conventional reactive sputtering: 800 Å/min for Al2O3 film and 1000 Ta2O5 uniformity ±5% within area 10 cm diameter. These results used develop automated system. The superior characteristics are due the high‐rate metallic...
The present study investigates modulation by the Madden-Julian Oscillation (MJO) of storm track activity (STA) over North Pacific (NP) during boreal winter for El Nino and La Nina periods. STA defined vertically averaged synoptic eddy kinetic energy (EKE) greatly intensifies western (WNP) central eastern years, respectively, when MJO convection is located Indian Ocean (IO)-Maritime Continent. When moves into Pacific, in years suppressed (enhanced) at higher (lower) latitudes than years....
Abstract Over the past two decades, number of tropical cyclones (TCs) has decreased markedly in southeastern part western North Pacific (WNP) as a component interdecadal variation. This decrease partially been explained by an internal low‐frequency variability sea surface temperature (SST) Pacific, but influences external forcing remain unclear. Here we show that changes sulfate aerosol emissions contributed approximately 60% observed decreasing trends TC genesis frequency WNP for 1992–2011,...
The future changes in the Madden-Julian Oscillation (MJO) and its extratropical teleconnection East Asia during boreal winter are examined by analyzing 12 climate models with good simulation skills of MJO convective signal Coupled Model Intercomparison Project phase 3 (CMIP3). convection increases over western to central Indian Ocean (IO) under warming seven (MJO-plus models). However, it decreases other five (MJO-minus wintertime sea surface temperature (SST) exhibits more El Niño-like...
[1] Equatorial westerly wind bursts (WWBs) and their relationship with El Nino–Southern Oscillation (ENSO) in the 18 climate models presented World Climate Research Programme's Coupled Model Intercomparison Project phase 3 (CMIP3) are examined. Some depict a realistic eastward shift of collective occurrences WWBs over Pacific as warm pool expands eastward. These that frequent western preceding Nino peak, known to trigger or enhance Nino, tend reproduce background states ENSO more accurately....
Sphingosine 1-phosphate (S1P) has been suggested to be a positive regulator of plasminogen activator inhibitor 1 (PAI-1) in adipocytes, while some studies are not consistent with this prothrombotic property S1P. Since S1P is bound apolipoprotein M (apoM) on HDL or albumin plasma, we compared the properties these two forms PAI-1 induction.We investigated associations S1P, apoM, and concentrations plasma normal coronary artery (NCA), stable angina pectoris (SAP), acute syndrome (ACS) subjects...
