We assumed that the fundamental form of the Dirac equation γ<sub>μ</sub>(δ<sub>μ</sub>-S<sub>μ</sub>)Ψ=0 should describe the stable particles (the electron, the proton and the dark-matter-particle (dmp)) bound to themselves under the action of their own potentials S<sub>μ</sub>. The new equation reveals that self energy is consequence of self action, it also reveals that the spin angular momentum is consequence of the dynamic structure of the stable particles. The quantitative results are the determination of their relative masses as well as the determination of the electromagnetic coupling constant.展开更多

文摘Phlomoides,with 150-170 species,is the second largest and perhaps most taxonomically challenging genus within the subfamily Lamioideae(Lamiaceae).With about 60 species,China is one of three major biodiversity centers of Phlomoides.Although some Phlomoides species from China have been included in previous molecular phylogenetic studies,a robust and broad phylogeny of this lineage has yet to be completed.Moreover,given the myriad new additions to the genus,the existing infrageneric classification needs to be evaluated and revised.Here,we combine molecular and morphological data to investigate relationships within Phlomoides,with a focus on Chinese species.We observed that plastid DNA sequences can resolve relationships within Phlomoides better than nuclear ribosomal internal and external transcribed spacer regions(nrITS and nrETS).Molecular phylogenetic analyses confirm the monophyly of Phlomoides,but most previously defined infrageneric groups are not monophyletic.In addition,morphological analysis demonstrates the significant taxonomic value of eight characters to the genus.Based on our molecular phylogenetic analyses and morphological data,we establish a novel section Notochaete within Phlomoides,and propose three new combinations as well as three new synonyms.This study presents the first molecular phylogenetic analyses of Phlomoides in which taxa representative of the entire genus are included,and highlights the phylogenetic and taxonomic value of several morphological characters from species of Phlomoides from China.Our study suggests that a taxonomic revision and reclassification for the entire genus is necessary in the future.

文摘Species of the ciliate class Heterotrichea Stein,1859 are a cosmopolitan group of unicellular eukaryotic microorganisms,many of which have been widely used as models in various fields of research such as regenerative biology,functional ecol-ogy,environmental toxicology,and symbiotic behavior.However,species identification in the heterotrich family Condylos-tomatidae,especially the most species-rich and type genus Condylostoma Bory de Saint-Vincent,1824,remains challenging due to incomplete original descriptions,few reliable distinguishing characters,and overlapping features between different species.This study presents an updated revision of Condylostoma and its related genus Condylostomides da Silva Neto,1994 based on descriptions of five species,including nine populations collected from China,using both morphological and molecular methods.The main findings are as follows:(1)43 nominal species and about 130 populations are reviewed,result-ing in the recognition of 30 valid species of Condylostoma and eight valid species of Condylostomides;(2)keys,synonyms,biogeographic distributions and amended/improved diagnoses of all valid species are provided;(3)based on the available data,four new Condylostoma species(C.marinum sp.nov.,C.petzi sp.nov.,C.villeneuvei sp.nov.,and C.microstomum sp.nov.),one new combination(Condylostomides minimus(Dragesco,1954)comb.nov.&nom.corr.),and two corrected names(Condylostoma ancestrale Villeneuve-Brachon,1940 nom.corr.and Condylostomides nigrus(Dragesco,1960)nom.corr.)are suggested;(4)cryptic species are detected and proposed for the first time to form the Condylostoma curvum spe-cies complex;(5)three highly confusing Condylostoma species,C.kris,C.spatiosum,and C.minutum,are redefined for the first time based on modern taxonomic methods;(6)a‘flagship’species,Condylostomides coeruleus,is recorded for the first time from the continent of Asia,substantially expanding its biogeography;(7)ciliature adjacent to the distal end of the paroral membrane within the family Condylostomatidae is uniformly defined as frontal membranelles and is classified into three patterns according to the arrangement of kinetosomes,which serve as important key features.

文摘Image description task is the intersection of computer vision and natural language processing,and it has important prospects,including helping computers understand images and obtaining information for the visually impaired.This study presents an innovative approach employing deep reinforcement learning to enhance the accuracy of natural language descriptions of images.Our method focuses on refining the reward function in deep reinforcement learning,facilitating the generation of precise descriptions by aligning visual and textual features more closely.Our approach comprises three key architectures.Firstly,it utilizes Residual Network 101(ResNet-101)and Faster Region-based Convolutional Neural Network(Faster R-CNN)to extract average and local image features,respectively,followed by the implementation of a dual attention mechanism for intricate feature fusion.Secondly,the Transformer model is engaged to derive contextual semantic features from textual data.Finally,the generation of descriptive text is executed through a two-layer long short-term memory network(LSTM),directed by the value and reward functions.Compared with the image description method that relies on deep learning,the score of Bilingual Evaluation Understudy(BLEU-1)is 0.762,which is 1.6%higher,and the score of BLEU-4 is 0.299.Consensus-based Image Description Evaluation(CIDEr)scored 0.998,Recall-Oriented Understudy for Gisting Evaluation(ROUGE)scored 0.552,the latter improved by 0.36%.These results not only attest to the viability of our approach but also highlight its superiority in the realm of image description.Future research can explore the integration of our method with other artificial intelligence(AI)domains,such as emotional AI,to create more nuanced and context-aware systems.
文摘Cross-lingual image description,the task of generating image captions in a target language from images and descriptions in a source language,is addressed in this study through a novel approach that combines neural network models and semantic matching techniques.Experiments conducted on the Flickr8k and AraImg2k benchmark datasets,featuring images and descriptions in English and Arabic,showcase remarkable performance improvements over state-of-the-art methods.Our model,equipped with the Image&Cross-Language Semantic Matching module and the Target Language Domain Evaluation module,significantly enhances the semantic relevance of generated image descriptions.For English-to-Arabic and Arabic-to-English cross-language image descriptions,our approach achieves a CIDEr score for English and Arabic of 87.9%and 81.7%,respectively,emphasizing the substantial contributions of our methodology.Comparative analyses with previous works further affirm the superior performance of our approach,and visual results underscore that our model generates image captions that are both semantically accurate and stylistically consistent with the target language.In summary,this study advances the field of cross-lingual image description,offering an effective solution for generating image captions across languages,with the potential to impact multilingual communication and accessibility.Future research directions include expanding to more languages and incorporating diverse visual and textual data sources.
文摘The Dirac equation γ<sub>μ</sub>(δ<sub>μ</sub>-eA<sub>μ</sub>)Ψ=mc<sup>2</sup>Ψ describes the bound states of the electron under the action of external potentials, A<sub>μ</sub>. We assumed that the fundamental form of the Dirac equation γ<sub>μ</sub>(δ<sub>μ</sub>-S<sub>μ</sub>)Ψ=0 should describe the stable particles (the electron, the proton and the dark-matter-particle (dmp)) bound to themselves under the action of their own potentials S<sub>μ</sub>. The new equation reveals that self energy is consequence of self action, it also reveals that the spin angular momentum is consequence of the dynamic structure of the stable particles. The quantitative results are the determination of their relative masses as well as the determination of the electromagnetic coupling constant.
文摘The Black-winged Monarch(Monarcha frater)inhabits low-mid elevation forests across New Guinea and far northeastern Australia.Of its four recognized subspecies,M.f.canescens is migratory,breeding in tropical north-eastern Australia from approximately November–March.The non-breeding range of M.f.canescens,apart from some individuals overwintering in Australia,has been unknown for>100 years.Data from 194 New Guinean and Australian specimens and a literature review have not solved this mystery;the narrow latitudinal range of the intratropical migration may inhibit use of GPS loggers in resolving the migration route.Field work in central and western parts of southern New Guinea is needed.Specimen data,however,revealed an essentially overlooked population in north-western New Guinea east of the Bird's Head Peninsula phenotypically indistinguishable from nominate M.f.frater of that Peninsula.Future genomic analysis of the complex will be largely done from toepad skin because frozen tissue samples for DNA analysis exist only of four individuals of what we suggest should be elevated to species rank as M.periophthalmicus.We discuss how genomic analysis might distinguish among alternative taxonomic hypotheses of one,two or three species.We suggest English names for what we consider to be three diagnosable taxa worth recognizing at species rank in this group:Arfak Monarch corresponding to M.frater(Bird's Head Peninsula and the“new”population of north-western New Guinea);Pearly Monarch for M.canescens(Australia and still unknown non-breeding range),and Masked Monarch for M.periophthalmicus(including kunupi,elsewhere in New Guinea).

文摘Until now the genus Amana(Liliaceae),known as ’East Asian tulips’,has contained just seven species.In this study,a phylogenomic and integrative taxonomic approach was used to reveal two new species,Amana nanyueensis from Central China and A.tianmuensis from East China.A.nanyueensis resembles Amana edulis in possessing a densely villous-woolly bulb tunic and two opposite bracts,but differs in its leaves and anthers.Amana tianmuensis resembles Amana erythronioides in possessing three verticillate bracts and yellow anthers,but differs in aspects of its leaves and bulbs.These four species are clearly separated from each other in principal components analysis based on morphology.Phylogenomic analyses based on plastid CDS further support the species delimitation of A.nanyueensis and A.tianmuensis and suggests they are closely related to A.edulis.Cytological analysis shows that A.nanyueensis and A tianmuensis are both diploid(2n=2x=24),different from A edulis,which is either diploid(northern populations) or tetraploid(southern populations,2n=4x=48).The pollen morphology of A.nanyueensis is similar to other Amana species(single-groove germination aperture),but A.tianmuensis is quite different because of the presence of a sulcus membrane,which creates the illusion of double grooves.Ecological niche modelling also revealed a niche differentiation between A.edulis,A.nanyueensis and A.tianmuensis.
文摘How to think a unique and determinative turn in analytic philosophy of mind?To answer this question this article first presents an attempt to render clear that analytic phenomenology,by contrast with conceptions of phenomenology of the XXth century,beneficially dispenses with several methodological and conceptual assumptions that were assumed to be compulsory,as phenomenological reduction,a notion of synthesis,and a philosophical notion of the a priori.It then presents some eventual difficulties to the achievement of a phenomenological turn within analytic philosophy,which are,the neglect of historicity,abstractionism,the acknowledgement of the place of language in our lives,and solipsism.It finally presents several demands that concern the felicity of contemporary analytic phenomenologies,namely,anti-abstractionism,fallibilism,attention to polyadic relations,and the integration of ecological and decolonial concerns of our cultures.
文摘Mark Twain is one of the most famous writers of the nineteenth century,his works have a large number of descriptions of dreams,in Mark Twain’s short story My Platonic Sweetheart,the author describes a dream that constantly repeats itself in his life.The dream description in the novel is not only part of the narrative structure of the article,but also expresses the theme of the article,through the close reading of the text,taking dream description as the starting point,the author of this thesis analyzes the dream description in My Platonic Sweetheart,exploring the thematic role of dream description in the novel,and analyzing what the author wants to express and how the author expresses his spiritual pursuit through dream description.
文摘Audio description(AD),unlike interlingual translation and interpretation,is subject to unique constraints as a spoken text.Facilitated by AD,educational videos on COVID-19 anti-virus measures are made accessible to the visually disadvantaged.In this study,a corpus of AD of COVID-19 educational videos is developed,named“Audio Description Corpus of COVID-19 Educational Videos”(ADCCEV).Drawing on the model of Textual and Linguistic Audio Description Matrix(TLADM),this paper aims to identify the linguistic and textual idiosyncrasies of AD themed on COVID-19 response released by the New Zealand Government.This study finds that linguistically,the AD script uses a mix of complete sentences and phrases,the majority being in Present Simple tense.Present participles and the“with”structure are used for brevity.Vocabulary is diverse,with simpler words for animated explainers.Third-person pronouns are common in educational videos.Color words are a salient feature of AD,where“yellow”denotes urgency,and“red”indicates importance,negativity,and hostility.On textual idiosyncrasies,coherence is achieved through intermodal components that align with the video’s mood and style.AD style varies depending on the video’s purpose,from informative to narrative or expressive.
