The experimental data obtained from the reaction of ${}^{6}$Li projectiles at 2$A$ GeV on a fixed graphite target were analyzed to study invariant mass distributions $d+{\ensuremath{\pi}}^{\ensuremath{-}}$ and $t+{\ensuremath{\pi}}^{\ensuremath{-}}$. Indications signal in $t+{\ensuremath{\pi}}^{\ensuremath{-}}$ observed with significances 5.3 $\ensuremath{\sigma}$ 5.0 $\ensuremath{\sigma}$, respectively, when including production target, 3.7 5.2 excluding target. estimated mean values for...
Understanding Li-ion transport at the solid | interface is crucial to improving performance of all-solid-state batteries. Electrochemical four-electrode cells have been widely used for electrochemical measurements ion transports liquid and interfaces. However, there no report application interface, electrochemistry has not understood well. In this study, we develop an cell investigate interfaces between two sulfide electrolytes. The resistances are successfully evaluated by AC impedance...
High-resolution spectrometers for both incident beams and scattered particles have been constructed at the K1.8 beam line of Hadron Experimental Facility J-PARC. A point-to-point optics is realized between entrance exit QQDQQ magnets spectrometer. Fine-pitch wire chamber trackers hodoscope counters are installed in spectrometer to accept a high rate up 107 Hz. The superconducting kaon was transferred from KEK with modifications cryogenic system detectors. missing-mass resolution 1.9 ± 0.1...
Peroxisome proliferator-activated receptor γ (PPARγ) is a ligand-activated transcription factor that plays an important role in adipogenesis and glucose metabolism. The ligand-binding pocket (LBP) of PPARγ has large Y-shaped cavity with multiple subpockets where ligands can simultaneously bind cooperatively activate PPARγ. Focusing on this unique property the LBP, we describe novel two-step cell-based strategy to develop ligands. First, combination activates was identified using luciferase...
In situ reactions of metal ions or their compounds are important mechanisms by which particles alter lung immune responses. The authors hypothesized that major determinants the immunomodulatory effect any include its redox behavior/properties, oxidation state, and/or solubility, and toxicities arising from differences in physicochemical parameters manifest, part, via differential shifts iron (Fe) homeostasis. To test hypotheses, potentials for both pentavalent vanadium (VV; as soluble...
The pentaquark $\Theta^+$ has been searched for via the $\pi^-p \to K^-X$ reaction with beam momenta of 1.92 and 2.01 GeV/$c$ at J-PARC. A missing mass resolution 2 MeV (FWHM) was achieved but no sharp peak structure observed. upper limits on production cross section averaged over scattering angle from 2$^{\circ}$ to 15$^{\circ}$ in laboratory frame were found be less than 0.28 $\mu$b/sr 90\% confidence level both 1.92- 2.01-GeV/$c$ data. systematic uncertainty controlled within 10\%....
Abstract To maintain genome integrity for transfer to their offspring and order in cellular processes, all living organisms have DNA repair systems. Besides the well-conserved machineries, thriving extreme environments are expected developed efficient We recently discovered a novel endonuclease, which cleaves 5′ side of deoxyinosine, from hyperthermophilic archaeon, Pyrococcus furiosus . The designated as Endonulcease Q (EndoQ), recognizes uracil, abasic site xanthine, well hypoxanthine cuts...
The statistics of galactic cosmic rays (GCRs) invading the heliosphere are investigated using numerical simulations. First, a time stationary global is reproduced an MHD simulation. Then, motions large number GCR protons with initial Lorentz factor 10 ($\sim$ GeV) and 1000 1 TeV), distributed in interstellar space around heliosphere, numerically solved. We map positional distribution GCRs arriving at 50 AU from Sun. Our results show that arrival position depends on their energies. discuss...

Recently, the penetration of renewable energy has been increasing. Especially, wind power generation focused as technology to solve environmental problems. However, high farm (WF) may have a bad influence on system, caused by fluctuating outputs. This paper proposes scheduling operation method WF deal with ramp events in order dispatch stably and deliberately, using battery storage system (BESS). And evaluation BESS capacity clarifies required for this method.
Abstract With the aim of investigating deposition Au/Pd core–shell nanoparticles (NPs) on cathode materials to decrease charge transfer resistance, NPs were successfully synthesized and deposited LiFePO 4 coated with carbon (LiFePO /C) using ultrasound irradiation. Transmission electron microscopy observation confirmed that dispersed an average particle size 7.2 nm /C. An X-ray diffraction measurement evidenced a peak shifting from 38.2° 39.1° upon calcination at 400 °C in Ar atmosphere,...
Recently, the penetration of wind farm (WF) has been increasing because global warming and lack fossil energy resource. However, WF output fluctuate due to weather seasonality. Specially, long-term fluctuation is called “Ramp event”. It's difficult for dispatch power grid without controlling ramp events.

Renewable energy such as wind generation is a countermeasure against global warming and fossil-energy resource depletion. However, wind-farm (WF) output fluctuates because of unstable conditions the occurrence long-term fluctuations, which are called ramp events. WF power operator needs to observe grid code (GC) by controlling generators themselves or adjusting with energy-storage system (ESS). Accordingly, scheduling operation ESS forecast necessary. Scheduled has two parts: plans (SGP)...

Many heavy-duty coating systems have been used for protecting the tidal-splash zone of offshore steel structures. Practical film properties several types ultra-thick coatings, among them, are examined. They resin mortar coating, solventless epoxy polyurethane elastomer paint and glass flake various problems involved in their application techniques discussed. It has found that an ultra-thick, is best choice structures view its relatively durable performance, even if applied outdoor environment.
A large-vocabulary continuous-speech recognition (LVCSR) system was developed and evaluated. To evaluate the system, a Japanese business-newspaper speech corpus designed recorded. The so that is can be used for LVCSR research in same way Wall Street Journal (WSJ) corpus, example, English research. Since sentences are written without spaces between words, morphological analysis introduced to segment into words word n-gram language models could used. enable use of detailed (n/spl ges/3)...
Machine learning models traditionally assume that training and test data are independently identically distributed. However, in real-world applications, the distribution often differs from training. This problem, known as out-of-distribution generalization, challenges conventional models. Invariant Risk Minimization (IRM) emerges a solution, aiming to identify features invariant across different environments enhance robustness. IRM's complexity, particularly its bi-level optimization, has...
