Abstract

The potential of the muon colliders open up new possibilities for the exploration of new physics beyond the Standard Model. It is worthwhile to investigate whether muon colliders are suitable for studying gluonic quartic gauge couplings~(gQGCs), which can be contributed by dimension-8 operators in the framework of the Standard Model effective field theory, and are intensively studied recently. In this paper, we study the sensitivity of the process $\mu^+\mu^-\to j j \nu\bar{\nu}$ to gQGCs. Our result indicate that the muon colliders with c.m. energies larger than $4\;{\rm TeV}$ can be more sensitive to gQGCs than the Large Hadron Collider., Comment: 20 pages, 5 figures

Abstract

Searching for new physics~(NP) is one of the areas of high-energy physics that requires the most processing of large amounts of data. At the same time, quantum computing has huge potential advantages when dealing with large amounts of data. The principal component analysis~(PCA) algorithm may be one of the bridges connecting these two aspects. On the one hand, it can be used for anomaly detection, and on the other hand, there are corresponding quantum algorithms for PCA. In this paper, we investigate how to use PCA to search for NP. Taking the example of anomalous quartic gauge couplings in the tri-photon process at muon colliders, we find that PCA can be used to search for NP. Compared with the traditional event selection strategy, the expected constraints on the operator coefficients obtained by PCA based event selection strategy are even better., Comment: correct one of the author names

Abstract

To elucidate the variations in quality and volatile component changes in different forms of stored indica-japonica hybrid rice, a study was conducted with Yongyou 1540 rice as the test material. Under storage conditions of paddy, brown rice, and milled rice, compared to conventional warehousing, an investigation was conducted to assess the influence of low-temperature storage (15±1 ℃, RH 60%) on its quality (fatty acid value, sensory evaluation) and volatile components. Results showed that storing rice at low temperatures significantly enhanced sensory quality when comparing with conventional storage after six months, and the fatty acid value was notably superior after 12 months. Moreover, storing rice as paddy or brown rice significantly outperformed milled rice storage (at 12 months). Analysis using gas chromatography-ion mobility spectrometry (GC-IMS) to examine the volatile components of the rice under different treatments, aldehyde and ketone substances in rice stored for 6~12 months increased in comparison of fresh rice. Among these, the differences in volatile components were relatively minor between samples stored for 6 months and notably greater between samples stored for 12 months. Substances like 2-methyl-1-butanol, pentanal, hexanal, 3-methylbutanal were found in higher concentrations in room temperature samples compared to low-temperature storage, while cyclohexanone, 2-butanone, butanal, 3-hydroxy-2-butanone were lower in concentration. In conclusion, low-temperature storage of paddy or brown rice maintained the quality and volatile components of indica-japonica hybrid rice better than those of conventional storage. This research can provide essential data and theoretical foundations for post-harvest storage and production of indica-japonica hybrid rice.

Abstract

Agricultural products usually contain a large number of spoilage bacteria and endogenous enzymes, which can adversely affect the quality of agricultural products. Radio frequency is a kind of dielectric heating technology, which has fast heating speed and high efficiency, can effectively inactivate microorganisms and endogenous enzymes in agricultural products and has little influence on the quality of agricultural products， such as color, texture and nutritional composition, etc. This review summarized the mechanism of action of radiofrequency sterilization blunt enzyme technology and its application in agricultural products processing in recent years, and the shortcomings and solutions of radiofrequency sterilization blunt enzyme technology was pointed out. Moreover, the future application of radiofrequency sterilization blunt enzyme technology in agricultural products and food was also prospected.

Abstract

18 p., fot. col., mapas, tablas -- El artículo está sujeto a una licencia Creative Commons Attribution 4.0 International License., This study, using species distribution modeling (involving a new approach that allows for uncertainty), predicts the distribution of climatically suitable areas prevailing during the mid-Holocene, the Last Glacial Maximum (LGM), and at present, and estimates the potential formation of new habitats in 2070 of the endangered and rare Tertiary relict tree Davidia involucrata Baill. The results regarding the mid-Holocene and the LGM demonstrate that south-central and southwestern China have been long-term stable refugia, and that the current distribution is limited to the prehistoric refugia. Given future distribution under six possible climate scenarios, only some parts of the current range of D. involucrata in the mid-high mountains of south-central and southwestern China would be maintained, while some shift west into higher mountains would occur. Our results show that the predicted suitable area offering high probability (0.5‒1) accounts for an average of only 29.2% among the models predicted for the future (2070), making D. involucrata highly vulnerable. We assess and propose priority protected areas in light of climate change. The information provided will also be relevant in planning conservation of other paleoendemic species having ecological traits and distribution ranges comparable to those of D. involucrata., This study received financial support from the Pro Natura Foundation-Japan (2014), the Environmental Research and Technology Development Fund (S-14) of the Ministry of the Environment, Japan, the “Proyecto Intramural Especial, PIE” (grant no. 201630I024) from the CSIC, Spain, and the National Natural Science Foundation of China (NSFC 31300349).

Abstract

Previous studies indicate a preliminary association between age and circadian blood pressure (BP) variation. This association would be affected by confounding factors in real-world populations. The authors investigated whether this is a convincingly independent association in a real-world population of adults with hypertension. Clinical data and findings of 24-hour ambulatory BP monitoring were obtained from 297 consecutive adults with hypertension (60.19±0.77 years). BP dipping patterns were categorized based on the percentage of nocturnal BP drop. Multivariate linear regression analysis identified an independent correlation between age and percentage of nocturnal systolic BPdrop (β=-7.296; 95% CI, -10.430 to -4.162 [P<.001]). Reverse dippers were the oldest and extreme dippers were the youngest. A significant age difference was noted among patients grouped into four BP dipping patterns with and without adjustments for sex, body mass index, drugs, diabetes mellitus, smoking, 24-hour mean heart rate, and 24-hour mean systolic and diastolic BP.
