Abstract

This paper studies the total flavonoids extraction and activity in vitro of Rose rugosa cv. Plena residues from Shandong province. Single factor experiment and orthogonal experiment are designed to determine the optimal extraction conditions for flavonoids. The antioxidant and antimicrobial activities of total flavonoids in vitro are evaluated by free radical scavenging method and Oxford cup method. Results show that the optimal extraction process for flavonoids are as follows: set the ethanol concentration to 60%and the solid-liquid ratio of 1∶30, then shake the rose residues at 80 ℃ for 1.5 hours, after which run it ultrasonic treatment for 45 minutes at 140 W and 60 ℃. This process gives us the total flavonoids content of 58.53 mg/g. The extracted flavonoids from rose residues demonstrates good antioxidant activity. The scavenging rates of DPPH· radical, ABTS+ radical and hydroxyl radical are 91.58%, 73.71% and 467.91 U/mL respectively. The total flavonoids have good antimicrobial activity on Staphylococcus aureus and Bacillus cereus. The flavonoids could significantly inhibit Staphylococcus aureus. This study would laid a solid foundation for the comprehensive utilization of Rose rugosa cv. Plena residues.

Abstract

By introducing multiple levels quadrature amplitude modulation and matrix transform method,a multiple am-plitudes differential space-time coding（DSTC） scheme was developed.The scheme can avoid the performance loss of conventional DSTC schemes based on PSK modulation in high spectrum efficiency,and it can be applied to non-square code matrix.Compared with conventional PSK based single amplitude DSTC schemes,the developed scheme has higher spectrum efficiency by carrying information not only on phases but also on amplitudes.Moreover,it has linear decoding complexity,and higher code rate.Also,the performance of our DSTC scheme concatenated with channel codes was given.The simulations results show that our scheme has lower BER when compared with single amplitude DSTC schemes.And multiple amplitudes DSTC concatenated with channel coding also outperform corresponding single amplitude DSTC.

Abstract

Extremely large non-saturating magnetoresistance has recently been reported for a large number of both topologically trivial and non-trivial materials. Different mechanisms have been proposed to explain the observed magnetotransport properties, yet without arriving to definitive conclusions or portraying a global picture. In this work, we investigate the transverse magnetoresistance of materials by combining the Fermi surfaces calculated from first principles with the Boltzmann transport theory approach relying on the semiclassical model and the relaxation time approximation. We first consider a series of simple model Fermi surfaces to provide a didactic introduction into the charge-carrier compensation and open-orbit mechanisms leading to non-saturating magnetoresistance. We then address in detail magnetotransport in three representative materials: (i) copper, a prototypical nearly free-electron metal characterized by the open Fermi surface that results in an intricate angular magnetoresistance, (ii) bismuth, a topologically trivial semimetal in which very large magnetoresistance is known to result from charge-carrier compensation, and (iii) tungsten diphosphide WP2, a recently discovered type-II Weyl semimetal that holds the record of magnetoresistance in compounds. In all three cases our calculations show excellent agreement with both the field dependence of magnetoresistance and its anisotropy measured at low temperatures. Furthermore, the calculations allow for a full interpretation of the observed features in terms of the Fermi surface topology. These results will help addressing a number of outstanding questions, such as the role of the topological phase in the pronounced large non-saturating magnetoresistance observed in topological materials., Comment: 13 pages, 9 figures

Abstract

Palm fungi are a diverse and unique group mostly found on Arecaceae hosts. They have been studied for approximately 200 years resulting in a large number of known fungal species representing over 700 genera. The timeline of palm fungal studies could be roughly divided into three phases, based on the methods and frequency of reports. They are the "Historical palm fungi era", "Classical palm fungi era" and "Molecular palm fungi era". In the first two periods, the identification of palm fungi was based on morphology, which resulted in a considerable number of morphological species scattered across the data in books, monographs and papers. With the advancement of molecular techniques, studies on palm fungi accelerated. A large number of new species were introduced in the molecular era, especially from Asia, including China and Thailand. However, there is a necessity to link these three generations of studies into a single platform combining data related to host factors, geography and utilisation. Herein, we introduce the palm fungi website: https://palmfungi.org, an integrated data platform for interactive retrieval, based on palm and fungal species. This website is not only a portal for the latest, comprehensive species information on palm fungi, but also provides a new platform for fungal researchers to explore the host-specificity of palm fungi. Additionally, this study uses palmfungi.org and related data to briefly discuss the current status of research on the distribution of palm fungi populations, showing how palmfungi.org links fungi with their palm hosts. Furthermore, the website will act as a platform for collaboration amongst taxonomists, plant pathologists, botanists, ecologists and those who are interested in palms and their relationship with ecological sustainability.

Abstract

Hydrogen production from photocatalysis via the usage of multicomponent photocatalysts represents a promising pathway for carbon peaking and carbon neutrality, owing to their structural advantages in dealing with the three crucial processes in photocatalysis, namely, light harvesting, charge transfer, and surface redox reactions. We demonstrate the fabrication of a MOF‐based multicomponent photocatalyst, denoted as semiconductor/MOF/cocatalyst, by a one‐pot electrochemical synthetic route. The as‐fabricated multicomponent photocatalyst has a clean interface among the components, leading to close connections that contribute to high‐quality heterojunction and facilitate photogenerated charge transfer and separation, thereby the efficient hydrogen evolution. The hydrogen production rate of the resultant ZrO2/Zr‐MOF/Pt is 1327 μmol ⋅ g−1 ⋅ h−1, which is much higher than that of ZrO2/Zr‐MOF (15 μmol ⋅ g−1 ⋅ h−1) and pure Zr‐MOF (10.1 μmol ⋅ g−1 ⋅ h−1), as well as the photodeposited‐Pt products ZrO2/Zr‐MOF/PtPD (287 μmol ⋅ g−1 ⋅ h−1) and Zr‐MOF/PtPD (192 μmol ⋅ g−1 ⋅ h−1) obtained by the step‐wise synthetic approach. The work gives a good inspiration for the rational design and construction of MOF‐based multicomponent photocatalysts through the one‐pot electrosynthesis. [ABSTRACT FROM AUTHOR]

Abstract

Numerical simulations are performed for a rotating two-species Bose condensate confined by a harmonic potential. The particle numbers of each species are unequal. When the rotational speed exceeds a critical value, the majority species reside in the center of the potential while the minority species is pushed out to the outskirts, forming a giant vortex hole to contain the majority species. A novel annular Skyrmion forms at the interface of the two species., Comment: 5 pages, 5 figures

Abstract

The conventional Walsh function just takes values of +1 and −1 and can only track limited signal states. However, based on the characteristics of Walsh functions that can capture the frequency of square wave signals, this article proposes a generalized Walsh transform algorithm to process multi-valued rectangular wave signals. As an extension of the traditional Walsh functions, generalized Walsh functions have advantages in signal frequency matching and sequency spectrum amplitude extraction, which makes them well suited to express the valuable signal. First, we infer the invariance displacement theory in the time and sequency domains, limiting the value of a circular time shift to ensure the concentrated distribution of the signal sequency energy. This limitation lays a good foundation for constructing generalized Walsh functions. Then, two types of generalized Walsh functions are built by combining the characteristics of different periodic rectangular waves. We deduce two properties of orthogonality and completeness to prove the ability of the constructed functions to match the frequency and the extracted energy. Finally, we compare multiple filtering methods to verify the reliability of the proposed method. [ABSTRACT FROM AUTHOR]

Abstract

Bambusicola autumnalis R.R. Liang, S.N. Zhang and Jian K. Liu, sp. nov. MycoBank: 847551; FIGURE 2. Etymology: —The epithet “ autumnalis ” refers to the season “autumn” when the fungus was collected. Holotype:—HKAS 126508 Saprobic on dead bamboo branches. Sexual morph: Ascostromata solitary to gregarious, rarely scattered, immersed to erumpent, pseudostromatic, visible as bumped areas with cracks and a central black minute papilla, in vertical section conical to subglobose, ostiolate, periphysate, individual locules 190–325 μm high, 215–295 μm diam (x = 280 × 250 µm, n = 10). Peridium 19–43 μm, composed of several layers of thick-walled, brown cells of textura angularis. Hamathecium 1–1.9 μm wide, trabecular pseudoparaphyses, anastomosing, hyaline, remotely septate. Asci 52–102 × 8–17 µm (x = 71 × 12 µm, n = 20), 8-spored, bitunicate, fissitunicate, long cylindric-clavate, shortly pedicellate, apically rounded with a minute ocular chamber. Ascospores 22–30 × 4.5–7 µm (x = 27 × 5 µm, n = 30), overlapping bi-seriate or multi-seriate, fusiform, 1-septate, constricted at the septum, guttulate, smooth-walled, surrounded by a thin, inconspicuous mucilaginous sheath. Asexual morph: Undetermined. Culture characteristics:—Colonies on PDA reaching 28–32 mm after 4 weeks incubated at 25 °C in dark, circular, dry, mycelium velvety, milky white to pale yellow, reverse yellow to light brown. Material examined:— CHINA, Sichuan province, Chengdu city, Chengdu Botanical Garden, 30°76.48’ N, 104°13.03’ E, 516 m elevation, on dead branches of bamboo in a terrestrial environment, 21 Nov. 2022, R.R. Liang, (HKAS 126508, holotype), ex-holotype living culture CGMCC 3.24280; ibid., HUEST 23.0001, isotype, ex-isotype living culture UESTCC 23.0001. Notes:—Multi-gene phylogenetic analysis showed that our isolates belong to Bambusicola and are closely related to B. guttulata (FIGURE 1). However, it is not able to compare their morphology as the latter species only represented by a coelomycetous asexual morph. Nevertheless, Bambusicola autumnalis differs from B. guttulata in their nucleotide sequences, viz. SSU (6/950), ITS (44/450), LSU (17/800), RPB2 (73/993) and TEF1-α (49/959), respectively. Morphologically, Bambusicola autumnalis resembles B. loculata in having stromatic ascomata, 8-spored, cylindric asci, and narrowly fusiform, 1-septate ascospores surrounded by an inconspicuous sheath (Dai et al. 2015). However, they have different dimensions of asci (52–102 × 8–17 μm vs. 80–105 × 8–13 μm) and ascospores (22–30 × 4.5–7 µm vs. 22–26.5 × 5–6), and the bumped ascostromata with cracks of B. autumnalis also differs from B. loculata. Moreover, the two species are phylogenetically distinct (FIGURE 1)., Published as part of Liang, Rui-Ru, Zhang, Sheng-Nan & Liu, Jian-Kui, 2023, Bambusicola autumnalis sp. nov., a bambusicolous ascomycete from Sichuan province, China, pp. 203-211 in Phytotaxa 601 (3) on page 208, DOI: 10.11646/phytotaxa.601.3.1, http://zenodo.org/record/8141736, {"references":["Dai, D.
