Korean has both syntactic and morphological causatives. A distinguishing characteristic of the former is that the causee argument may take nominative case. This article studies the syntax and ...semantics of causative sentences with nominative causees in Korean. It is argued that causative sentences with nominative causees have the following properties: Syntactically, the construction involves only two arguments, namely the causer and the caused event; and the causee argument serves as the subject of the caused event. In terms of semantics, under default intonation, the focus of the construction is the entire caused event. Typically, the nominative causee construction is used to express events in which the causee is volitional and/or lacks control of the caused event. The focus of this article is to investigate how the lexical semantics of a verbal root and the construction it appears in affect causativization. It shows that nominative causee is blocked in two cases, the Nominative Object Construction (NOC) and
In recent years, online lending has created many risks while providing lending convenience to Chinese individuals and small and medium-sized enterprises. The timely assessment and prediction of the ...status of industry indicators is an important prerequisite for effectively preventing the spread of risks in China's new financial formats. The role of investor sentiment should not be underestimated. We first use the BERT model to divide investor sentiment in the review information of China's online lending third-party information website into three categories and analyze the relationship between investor sentiment and quantitative indicators of online lending product transactions. The results show that the percentage of positive comments has a positive relationship to the borrowing interest rate of P2P platforms that investors are willing to participate in for bidding projects. The percentage of negative comments has an inverse relationship to the borrowing period. Second, after introducing investor sentiment into the long short-term memory (LSTM) model, the average RMSE of the three forecast periods for borrowing interest rates is 0.373, and that of the borrowing period is 0.262, which are better than the values of other control models. Corresponding suggestions for the risk prevention of China's new financial formats are made.

materials, a new class of high-entropy oxides, were synthesized by nebulized spray pyrolysis and subsequent high-temperature annealing. Various metal ...species (M = Ni, Co, Mn, Al, Fe, Zn, Cr, Ti, Zr, Cu) could be incorporated into this structure type, and in most cases, single-phase oxides were obtained. Delafossite structures are well known and the related materials are used in different fields of application, especially in electrochemical energy storage (e.g., LiNi
Co

NCM). The transfer of the high-entropy concept to this type of materials and the successful structural replication enabled the preparation of novel compounds with unprecedented properties. Here, we report on the characterization of a series of Delafossite-type high-entropy oxides by means of TEM, SEM, XPS, ICP-OES, Mössbauer spectroscopy, XRD including Rietveld refinement analysis, SAED and STEM mapping and discuss about the role of entropy stabilization. Our experimental data indicate the formation of uniform solid-solution structures with some Li/M mixing.
High entropy oxides (HEOs) with chemically disordered multi-cation structure attract intensive interest as negative electrode materials for battery applications. The outstanding electrochemical ...performance has been attributed to the high-entropy stabilization and the so-called 'cocktail effect'. However, the configurational entropy of the HEO, which is thermodynamically only metastable at room-temperature, is insufficient to drive the structural reversibility during conversion-type battery reaction, and the 'cocktail effect' has not been explained thus far. This work unveils the multi-cations synergy of the HEO Mg

O at atomic and nanoscale during electrochemical reaction and explains the 'cocktail effect'. The more electronegative elements form an electrochemically inert 3-dimensional metallic nano-network enabling electron transport. The electrochemical inactive cation stabilizes an oxide nanophase, which is semi-coherent with the metallic phase and accommodates Li
ions. This self-assembled nanostructure enables stable cycling of micron-sized particles, which bypasses the need for nanoscale pre-modification required for conventional metal oxides in battery applications. This demonstrates elemental diversity is the key for optimizing multi-cation electrode materials.
Nickel cobalt phosphides electrocatalysts have shown great potential for hydrogen evolution reaction (HER) but further improvements are necessary. Here, nickel cobalt phosphide nanosheets were ...synthesized via electrodeposition followed by phosphorization methodology. The relationships between phosphorization temperature and the structure or hydrogen evolution reaction (HER) activity were studied. The catalyst phosphated at 350 °C (NiCoP-350/CC) displayed excellent HER performance in alkaline media with a low overpotential of 59 mV at the current density of 10 mA cm−2 (η10 = 59 mV). This could be attributed to the formation and better dispersion of active NiCoP crystalline phase on the surface of carbon cloth.

Non-aqueous sodium-ion batteries (SiBs) are a viable electrochemical energy storage system for grid storage. However, the practical development of SiBs is hindered mainly by the sluggish kinetics and ...interfacial instability of positive-electrode active materials, such as polyanion-type iron-based sulfates, at high voltage. Here, to circumvent these issues, we proposed the multiscale interface engineering of Na

, where bulk heterostructure and exposed crystal plane were tuned to improve the Na-ion storage performance. Physicochemical characterizations and theoretical calculations suggested that the heterostructure of Na

In this paper, we study a Riemann-Hilbert problem related to inhomogeneous complex partial differential operators of higher order on the unit disk. Applying the Cauchy-Pompeiu formula, we find out ...the solvable conditions and obtain the representation of the solutions. Then, we investigate the boundary value problems for bi-polyanalytic functions with the Dirichlet and Riemann-Hilbert boundary conditions, obtain the specific solution and the solvable conditions, and extend the conclusion to the corresponding higher-order problems. Therefore, we obtain the solution to the half-Neumann problem of higher order for bi-polyanalytic functions.
Abstract
Anaplasma
species, which are distributed worldwide, are gram-negative obligate intracellular tick-borne bacteria that pose a threat to human and animal health.
Haemaphysalis longicornis
...ticks play a vital role as vectors in the transmission of
Anaplasma
pathogens. However, the
Anaplasma
species carried by
H. longicornis
in China are yet to be characterized. In this study, 1074
H. longicornis
specimens were collected from goats in four provinces of China from 2018 to 2019 and divided into 371 sample pools. All tick sample pools were examined for the presence of
Anaplasma
species via nested PCR amplification of 16S ribosomal RNA, major surface protein 4 (
msp4
), or citric acid synthase (
gltA
) genes, which were sequenced to determine the molecular and phylogenetic characteristics of the isolates. The overall
Anaplasma
spp-positive rate of
H. longicornis
was determined to be 26.68% (99/371). The percentage prevalence of
A. phagocytophilum
-like1,
A. bovis
,
A. ovis
,
A. marginale
, and
A. capra
were 1.08% (4/371), 13.21% (49/371), 13.21% (49/371), 1.35% (5/371), and 10.24% (38/371), respectively, and the co-infection rate of two or more types of
Anaplasma
was 6.47% (24/371). Phylogenetic analyses led to the classification of
A. phagocytophilum
into an
A. phagocytophilum
-like1 (
Anaplasma
sp. Japan) group.
Anaplasma bovis
sequences obtained in this study were 99.8–100% identical to those of an earlier strain isolated from a Chinese tick (GenBank accession no. KP314251).
Anaplasma ovis
sequences showed 99.3–99.6% identity to an
A. ovis
human strain identified from a Cypriot patient (GenBank accession no. FJ460443). Only one
msp4
sequence of
A. marginale
was detected and was grouped with those of other
A. marginale
isolates, and these
A. capra
isolates obtained in this present study may be zoonotic. The detection and characterization of four
Anaplasma
species in
H. longicornis
in this study have added to the current knowledge of the parasite and provided data on multiple
Anaplasma
species with veterinary and medical significance from four provinces of China.
