Abstract

Ethylene response factors (ERFs) comprise one of the largest transcription factor families in many plant species. Tobacco (Nicotiana tabacum) ERF3 (NtERF3) and other ERF-associated amphiphilic repression (EAR) motif-containing ERFs are known to function as transcriptional repressors. NtERF3 and several repressor-type ERFs induce cell death in tobacco leaves and are also associated with a defence response against tobacco mosaic virus (TMV). We investigated whether transcriptional activator-type NtERFs function together with NtERF3 in the defence response against TMV infection by performing transient ectopic expression, together with gene expression, chromatin immunoprecipitation (ChIP) and promoter analyses. Transient overexpression of NtERF2 and NtERF4 induced cell death in tobacco leaves, albeit later than that induced by NtERF3. Fusion of the EAR motif to the C-terminal end of NtERF2 and NtERF4 abolished their cell death-inducing ability. The expression of NtERF2 and NtERF4 was upregulated at the early phase of N gene-triggered hypersensitive response (HR) against TMV infection. The cell death phenotype induced by overexpression of wild-type NtERF2 and NtERF4 was suppressed by co-expression of an EAR motif-deficient form of NtERF3. Furthermore, ChIP and promoter analyses suggested that NtERF2, NtERF3 and NtERF4 positively or negatively regulate the expression of NtERF3 by binding to its promoter region. Overall, our results revealed the cell death-inducing abilities of genes encoding activator-type NtERFs, including NtERF2 and NtERF4, suggesting that the HR-cell death signalling via the repressor-type NtERF3 is competitively but coordinately regulated by these NtERFs.

Abstract

Reflecting COVID-19 outbreak that prevents educators from making close contacts with students, digitalization of language teaching is gradually getting educators’ attention. With respect to this situation, this research conducted an experiment of using Virtual Reality (VR) materials for 69 English as a STEM-major Foreign Language (EFL) learners at a Japanese university. Polishing usability of Virtual Reality (VR) English language education materials could improve the learners’ performance of English language use. However, careless use of VR materials could fail, unless the educators consider its technical and pedagogical limitations. The experiment used pairs of Virtual reality headset with two scenarios (international conference and restaurant). From pre-post experiment surveys on speaking anxiety scale, students with higher Test of English for International Communication (TOEIC) listening scores showed more anxiety on speaking. Also, post-experiment open-ended questionnaires suggested that usability of VR materials should be improved.

Abstract

Physical chemistry, chemical physics 25(19), 13784 - 13791 (2023). doi:10.1039/D2CP05942H, We present a study on molecular-frame photoelectron angular distributions (MFPADs) of small molecules using circularly polarized synchrotron light. We find that the main forward-scattering peaks of the MFPADs are slightly tilted with respect to the molecular axis. This tilt angle is directly connected to the molecular bond length by a simple, universal formula. We apply the derived formula to several examples of MFPADs of C 1s and O 1s photoelectrons of CO, which have been measured experimentally or obtained by means of ab initio modeling. In addition, we discuss the influence of the back-scattering contribution that is superimposed over the analyzed forward-scattering peak in the case of homo-nuclear diatomic molecules such as N2., Published by RSC Publ., Cambridge

Physical chemistry, chemical physics 24(44), 27121 - 27127 (2022). doi:10.1039/D2CP02408J special issue: "Ions, electrons, coincidences and dynamics: Festschrift for John H.D. Eland", During the last decade, X-ray free-electron lasers (XFELs) have enabled the study of light–matter interaction under extreme conditions. Atoms which are subject to XFEL radiation are charged by a complex interplay of (several subsequent) photoionization events and electronic decay processes within a few femtoseconds. The interaction with molecules is even more intriguing, since intricate nuclear dynamics occur as the molecules start to dissociate during the charge-up process. Here, we demonstrate that by analyzing photoelectron angular emission distributions and kinetic energy release of charge states of ionic molecular fragments, we can obtain a detailed understanding of the charge-up and fragmentation dynamics. Our novel approach allows for gathering such information without the need of complex ab initio modeling. As an example, we provide a detailed view on the processes happening on a femtosecond time scale in oxygen molecules exposed to intense XFEL pulses., Published by RSC Publ., Cambridge

Abstract

Andes Large-area PArticle detector for Cosmic-ray physics and Astronomy (ALPACA) is an international experiment that applies southern very-high-energy (VHE) gamma-ray astronomy to determine the origin of cosmic rays around the knee energy region ($10^{15}\, {\rm eV} - 10^{16}\, {\rm eV}$). The experiment consists of an air shower (AS) array with a surface of $83, 000\, {\rm m}^2$ and an underground water Cherenkov muon detector (MD) array covering $5, 400\, {\rm m}^2$. The experimental site is at the Mt. Chacaltaya plateau in La Paz, Bolivia, with an altitude of $4, 740\, {\rm m}$ corresponding to $572\, {\rm g}/{\rm cm}^2$ atmospheric thickness. As the prototype experiment of ALPACA, the ALPAQUITA experiment aims to begin data acquisition in late 2021. The ALPAQUITA array consists of a smaller AS array ($18, 450\, {\rm m}^2$) and underground MD ($900\, {\rm m}^2$), which are now under construction. ALPAQUITA's sensitivity to gamma-ray sources is evaluated with Monte Carlo simulations. The simulation finds that five gamma-ray sources observed by H.E.S.S. and HAWC experiments will be detected by ALPAQUITA beyond 10 TeV and one out of these five - HESS J1702-420A - above 300 TeV in one calendar year observation. The latter finding means that scientific discussions can be made on the emission mechanism of gamma rays beyond 100 TeV from southern sources on the basis of the observational results of this prototype experiment., This is the manuscript accepted by Experimental Astronomy.

Abstract

Observation techniques of high-energy gamma rays using air showers have remarkably progressed via the Tibet AS$\gamma$, HAWC, and LHAASO experiments. These observations have significantly contributed to gamma-ray astronomy in the northern sky's sub-Peta electron volts (PeV) region. Moreover, in the southern sky, the ALPACA experiment is underway at 4,740\,m altitude on the Chacaltaya plateau in Bolivia. This experiment estimates the gamma-ray flux from the difference between the number of on-source and off-source events by real data, utilizing the gamma-ray detection efficiency calculated through Monte Carlo simulations, which in turn depends on the hadronic interaction models. Even though the number of cosmic-ray background events can be experimentally estimated, this model dependence affects the estimation of gamma-ray detection efficiency. However, previous reports have assumed that the model dependence is negligible and have not included it in the error of gamma-ray flux estimation. Using ALPAQUITA, the prototype experiment of ALPACA, we quantitatively evaluated the model dependence on hadronic interaction models for the first time. We evaluate the model dependence on hadronic interactions as less than 3.6\,\% in the typical gamma-ray flux estimation performed by ALPAQUITA; this is negligible compared with other uncertainties such as energy scale uncertainty in the energy range from 6 to 300 TeV, which is dominated by the Monte Carlo statistics. This upper limit of 3.6\,\% model dependence is expected to apply to ALPACA.

Abstract

The importance of Science Technology, Engineering, Arts, and Mathematics (STEAM) education has been strongly recognized over the last few years. STEAM education requires an approach to integrate these disciples, and robots and unmanned aerial vehicles (UAVs) are often utilized as ideal tools for hands-on STEAM education. Over the past few years, open source-based fully autonomous UAVs have been priced below $100. This fact also has allowed UAV Research and Development (R&D) to bring reverse innovation in education. This paper introduces our projects contributing to local communities, including R&D and STEAM educational programs that exploit open-source UAV platforms. We describe three examples of STEAM educational programs using UAV technologies: a three-day scratch-build UAV workshop at the Kirirom Institute of Technologies in Cambodia, a sailing robot development project at a private STEAM education and fabrication lab for children, VIVISTOP Kashiwanoha in Chiba, Japan, and an ongoing project of UAV R&D at Japan Aviation Academy whose framework is going to be extended to a workshop for local children in Ishikawa, Japan, with a local board of education.

Abstract

We present analytical expressions of momentum-resolved core-level photoemission time delay in a molecular frame of a heteronuclear diatomic molecule upon photoionization by a linearly polarized soft x-rays attosecond pulse. For this purpose, we start to derive a general expression of photoemission time delay based on the first order time dependent perturbation theory within the one electron and single channel model in the fixed-in-space system (atoms, molecules and crystals) and apply it to the core-level photoemission within the electric dipole approximation. By using multiple scattering theory and applying series expansion, plane wave and muffin-tin approximations, the core-level photoemission time delay $t$ is divided into three components, $t_{\rm abs}$, $t_{\rm path}$ and $t_{\rm sc}$, which are atomic photoemission time delay, delays caused by the propagation of photoelectron among the surrounding atoms and the scattering of photoelectron by them, respectively. We applied single scattering approximation to $t_{\rm path}$ and obtained $t_{\rm path}^{(1)}(k,\theta)$ with polarization vector parallel to the molecular axis for a heteronuclear diatomic molecule, where $\theta$ is the angle of measured photoelectron from the molecular axis. $t$ is approximated well with this simplified expression $t_{\rm path}^{(1)}(k,\theta)$ in the high energy regime ($k\gtrsim 3.5\,\, {\rm a.u.}^{-1}$), and the validity of this estimated result is confirmed by comparing it with multiple scattering calculations for C 1$s$ core-level photoemission time delay of CO molecules. $t_{\rm path}^{(1)}(k,\theta)$ shows characteristic dependence on $\theta$, it becomes zero at $\theta=0$, exhibits EXAFS type oscillation with $2kR$ at $\theta=\pi$, where $R$ is the bondlength, and gives just the travelling time of photoelectron from the absorbing atom to the neighbouring atom at $\theta=\pi/2$., Comment: 7 pages, 2 figures

Abstract

The purpose of this prospective study was to assess the ability of plasma vascular endothelial growth factor-A short isoforms (pVEGF-Asi) to predict bevacizumab (BV) efficacy and to explore other circulating biomarkers in metastatic colorectal cancer (mCRC) patients treated with modified FOLFOX6/XELOX plus BV (mFOLFOX6/XELOX + BV).Pre-treatment plasma samples were collected from 100 mCRC patients receiving first-line chemotherapy with mFOLFOX6/XELOX + BV. The plasma levels of 11 angiogenesis-associated molecules, including pVEGF-Asi and 22 cancer-associated gene mutations in circulating tumor DNA, were analyzed. For the primary endpoint, we assumed that the hazard ratio (HR) for progression-free survival (PFS) calculated using a Cox proportional hazards model was1.15, comparing patients with a high versus those with a low pVEGF-Asi level divided according to the median pVEGF-Asi value.The median value of pVEGF-Asi was 37 (range 6.5-262) pg/ml. The HR for PFS between the high and low pVEGF-Asi patient groups was 1.3 [95% confidence interval (CI) 0.8-2.1; log rank, P = 0.25], which was larger than the predefined threshold of 1.15. The multivariate analysis demonstrated that PFS was significantly associated with plasma intercellular adhesion molecule-1 (pICAM-1) (≥190.0 versus190.0 ng/ml; HR 2.1; 95% CI 1.3-3.5), RAS (mutant versus wild; HR 2.5; 95% CI 1.5-4.3), and FBXW7 (mutant versus wild; HR 2.8; 95% CI 1.2-6.8), whereas overall survival was significantly associated with pICAM-1 (HR 2.0; 95% CI 1.1-3.7) and RAS (HR 2.6; 95% CI 1.5-4.6).The addition of BV was unable to compensate for the poor PFS associated with a high pVEGF-Asi level, suggesting that pVEGF-Asi is unlikely to be a good predictive biomarker of the efficacy of mFOLFOX6/XELOX + BV therapy. The clinical significance of circulating ICAM-1, mutant RAS, and mutant FBXW7 levels should be studied further.

29. Effect of emotionally toned Malay language sounds on the brain: a NIRS analysis

Abstract

Speech recognition features such as emotion have always been involved in human communication. With the recent developments in the communication methods, researchers have investigated artificial and emotional intelligence to improve communication. This has led to the emergence of affective computing, which deals with processing information pertaining to human emotions. This study aims to determine positive influence of language sounds containing emotion on brain function for improved communication. Twenty-seven college-age Japanese subjects with no prior exposure to the Malay language listened to emotionally toned and emotionally neutral sounds in the Malay language. Their brain activities were measured using near-infrared spectroscopy (NIRS) as they listened to the sounds. A comparison between different NIRS signals revealed that emotionally toned language sounds had a greater impact on brain areas associated with attention and emotion. On the contrary, emotionally neutral Malay sounds affected brain areas involved in working memory and language processing. These results suggest that emotionally-charged sounds initiate listeners’ attention and emotion recognition even when the listeners do not understand the language. The ability to interpret emotions presents challenges in computer systems and robotics; therefore, we hope that our results can be used for the development of computational models of emotion for autonomous robot research in the field of communication.

Abstract

Emotions play an important role in human communication. We conducted a study to identify the effect of emotions in language sounds in terms of brain functions. The sounds of Japanese sentences spoken with and without emotion were reversed to eliminate their semantic influence on the subjects’ emotional perception. Three sets of sentences with non-emotional and happy, sad, and angry emotional tones were recorded and reversed. The brain activities of 20 native Japanese speakers in their twenties were monitored by near-infrared spectroscopy (NIRS) while they listened to the reversed Japanese sounds with and without the emotions. Our analysis of the experimental results demonstrated that almost all the brain areas monitored by the NIRS probes were activated more when the subjects listened to emotional language sounds than to non-emotional sounds. In particular, the frontopolar cortex area, which is associated with short-term memory, was significantly activated. Since short-term memory is known to provide important information for communication, these results suggest that emotional aspects of language sounds are essential for successful communication and thus should be implemented in human–robot communication systems.

Abstract

The ALPACA experiment is a new air shower experiment mainly aiming to explore the southern sky in the VHE gamma-ray regime beyond 100 TeV. As the prototype experiment, ALPAQUITA will start in late 2021. It consists of a surface air shower array (18,450 ${\rm m}^2$) and an underground muon detector array (900 ${\rm m}^2$). In this study, the performance of ALPAQUITA including the sensitivity to gamma-ray point sources is investigated using a Monte Carlo simulation to quantitatively evaluate the possibility of detection of gamma-ray sources in the prototype phase. Corsika 7.6400 and Geant4 v10.04.p02 are used to simulate air shower development in the atmosphere and detector response, respectively. The output data are then processed and analyzed in the same way as the experiment. As a result, the study finds that the air shower array has an energy resolution of $\pm21\%$ and the angular resolution of $\simeq 0.2^{\circ}$ for gamma rays with an energy of 100 TeV. The detection area of the air shower array for gamma rays reaches $\simeq 12, 600 \, {\rm m}^2$ above $\simeq 10\, {\rm TeV}$. The muon detector rejects $\simeq 99.9\%$ of background cosmic rays and maintains $\simeq 80\%$ of signal gamma rays. This high discrimination power will enable the detection of five southern known gamma-ray sources beyond 30 TeV and the extension of the energy spectrum of one out of the five, HESS J1702-420A, up to $\simeq 300\, {\rm TeV}$ during one calendar year observation. This study concludes that ALPAQUITA will provide data enough to discuss a hot topic of VHE gamma-ray astronomy before passing the baton to ALPACA.
