A promising strategy to enhance exciton dissociation and charge separation in phenolic-polymer-based photocatalysts is the generation utilization of benzenoid–quinoid donor–acceptor (D–A) couples inside phenolic resin frameworks. However, there are often more donors than acceptors due sluggish kinetics situ oxidation phenols quinoid methides, leading a mismatched D/A ratio. Herein, we report well-cross-linked with unity ratio synthesized by using phloroglucinol as building block for...
Sunway TaihuLight system is the first supercomputer offering a peak performance over 100 PFlops, which can be utilized to parallelize Non-dominated Sorting Genetic Algorithm II (NSGA-II), standard approach multi-objective optimization. However, insufficient off-chip memory bandwidth and limited scratchpad capacity of hinder improvement parallellizing NSGA-II. In this article, we propose an optimized parallel NSGA-II on system, called swNSGA-II, by utilizing process- thread-level parallelism...
This paper investigates EFL learners’ perception of prior knowledge and its roles in reading comprehension. It is based on a survey conducted among 400 students studying at secondary tertiary levels China. Through the analysis ranked multiple responses to questions posed questionnaire, shows that mainland China believe their command English vocabulary plays crucial role However as linguistic increases, they tend attach less importance knowledge, especially syntax formal structures. At same...
Recently, hypergraph learning has shown great potential in a variety of classification tasks. However, existing neural networks lack flexibility modeling and extracting high-order relationships among data. To solve this problem, we propose novel framework called wavelet (HGWNN) to explore the correlation 3D Firstly, considering non-uniformity most data sets real world, "data-driven" construction scheme, which is more efficient than some commonly used methods. Secondly, order efficiently...
This article reports on an exploratory study of English as a foreign language ( EFL ) teachers' attitudes, beliefs, and professional knowledge about teaching TEFL in preschool setting China. The investigation is structured two‐dimensional grid based Calderhead's (1996) categorisation attitudes beliefs Richards's division knowledge. It aims to explore relationships between their well connections views development program. shows that teachers demonstrate eminent form‐focused inclination...
In the low earth orbit (LEO) satellite Internet of Things (IoT), IoT devices can be distributed in remote areas (e.g., desert, ocean, and forest) for some special applications, where they are unable to have direct terrestrial network accesses only covered by satellite. But LEO scenario, it has face effects high doppler fast rate, due movement at speed utilization higher frequency bands. So fine synchronization track necessary done, even LORA. this paper, we propose a folded chirp-rate shift...
Abstract The coastal plain of Arctic Alaska contains many thousands lakes developed in continuous permafrost, which are ice-free for only 3–4 months each year. spatial pattern lake ice meltout 1870 (>10 ha) a ~9200 km2 study area near Barrow, Alaska, is analyzed using five Landsat scenes spanning 35-year record. For available year, spectra-based clustering algorithm used to differentiate water from during springtime and overlain on common shoreline template determine the percentage covering...
Background. Glioblastoma (GBM) is a highly prevalent brain tumor characterized by high rates of morbidity, recurrence, and mortality. While temozolomide (TMZ) commonly used as first-line treatment for this cancer, the emergence TMZ resistance limits its utility. The long noncoding RNA HOXA-AS2 reportedly drives GBM progression, but whether it can influence therapeutic to has yet be established. Methods. expression was analyzed in TMZ-resistant sensitive tissue samples cell lines qPCR. A...
As society develops by leaps and bounds, the expression of information transmission discourse is no longer dependent on a single language symbol, but interaction presentation multiple symbols.Therefore, traditional research text can comprehensively deeply analyze discourse.Multimodal analysis came into being gradually became hot topic in field linguistics recent years.Based visual grammar, this paper takes BBC natural documentary Planet Earth II as corpus.It selects large number images from...
The scalability of large language models (LLMs) in handling high-complexity and large-scale datasets has led to tremendous successes pivotal domains. While there is an urgent need acquire more training data for LLMs, a concerning reality the depletion high-quality public within few years. In view this, federated learning (FL) LLM fine-tuning paradigm recently been proposed facilitate collaborative on distributed private data, where multiple owners collaboratively fine-tune shared without...
This paper presents an analytical model for saturation throughput of IEEE 802.11 distributed coordination function (DCF) with multiple classes service based on varying the parameters used in medium access control. In particular, we show that relative differentiation can easily be achieved by initial contention window alone. The simulation results validity this model.
Abstract This paper is based on a qualitative inquiry that investigated the role of teachers' mediation in three different modes coding kindergarten foreign language classroom China (i.e. L2-coded intralinguistic mediation, L1-coded cross-lingual and L2-and-L1-mixed mediation). Through an exploratory examination varying effects kinds activating children's noticing prior knowledge learning designated game, study shows optimises not only exposure to target L2, but also capitalises efficiency...
