The Japanese Cabinet’s “Society 5.0” initiative seeks to create a sustainable society for human security and well-being through cyber-physical system. Keidanren (Japan Business Federation) is well aligned proactively deliver on the United Nations’ Sustainable Development Goals end poverty, protect planet, ensure prosperity all creation of Society 5.0. Typical collaborative ecosystem activities 5.0 in Japan are outlined this column.
The optical response of CdTe in the 1.1–5.6 eV photon-energy range at room temperature has been studied by spectroscopic ellipsometry. measured ε(E) data reveal distinct structures energies E0, E1, E1+Δ1, and E2 critical points. These are analyzed using various theoretical models, namely model dielectric function (MDF), harmonic-oscillator approximation (HOA), standard critical-point (SCP) model. Results satisfactory agreement with MDF calculations over entire photon energies. HOA (five...
It is imperative for humans to remain as central actors in the policy- and decisionmaking processes achieve a sustainable inclusive society. In this article, we outline challenges finding better actions realize Society 5.0 Sustainable Development Goals through evidence-based policy making using artificial intelligence.
The real (ε1) and imaginary (ε2) parts of the dielectric function, ε(E)=ε1(E)+iε2(E), PbSe have been measured by spectroscopic ellipsometry in 1.15–5.4 eV photon-energy range at room temperature. spectroscopic-ellipsometry data reveal distinct structures three critical-point energies (E1, E2, E3).

Prevention of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission has led to a shortage personal protective equipment (PPE) since the end 2019, when SARS-CoV-2 was identified in Wuhan, China. Quickly manufactured alternative PPE is high demand worldwide. We show how make an long-sleeve plastic gown for use as PPE, Toyonaka Poly Gown, using trash bag. thank all staff and doctors at Municipal Hospital.
The real ( ε 1 ) and imaginary 2 parts of the complex dielectric function, E )= )+ i ), SnTe have been measured by spectroscopic ellipsometry (SE) in 1.15-5.5 eV photon-energy range at room temperature.

It is found that both MDF SCP models successfully explain first-derivative [ d )/ ]. also shows excellent...
We developed a search-and-rescue robot to locate people in buildings following an earthquake disaster. In such environment, there may be obstacles as slopes, stairs, and rubble; however, with remote control systems, can delay obtaining image, due the wireless communications system, which makes maneuvering challenging. particular, it difficult climb slopes stairs. Here, we use acceleration sensor automate negotiation of stairs describe experimental results this approach.

A synthetic motion signal was previously proposed to perfect proscan conversion (see N. Suzuki et al., J. ITE, vol.42, no.9, p.966-972, 1988). Good characteristics were obtained without any modification of current IDTV (NTSC) receivers, and new standards not required. This found be only slightly visible in highly saturated image areas. An improved multiplexing method is for reducing the disturbance caused by signal, especially such accomplished adding a linear main signal. Hence, does leak...

Hydrogen-poor superluminous supernovae (SLSN-I) are a class of rare and energetic explosions discovered in untargeted transient surveys the past decade. The progenitor stars physical mechanism behind their large radiated energies ($\sim10^{51}$ erg) both debated, with one models primarily requiring rotational energy, while other requires very massive progenitors to either convert kinetic energy into radiation via interaction circumstellar material (CSM), or engender pair-instability...
