Clothing parsing is a challenging task. In this task, there are two main inherent challenges, which the fine-grained of small clothing components and missegmentation similar categories. To address these paper proposes phase contour enhancement network for parsing. It achieves improved accuracy while maintaining relatively complexity. Leveraging distinctive features maps, we introduce attention (PCEA) module to augment encoder's object edge information. further enrich model's feature...
While extensive research supported the facilitative role of motivation in general self-regulated learning (SRL) strategy use, its connection to writing-specific SRL use remains underexplored. Furthermore, exploration interplay between and second or foreign (L2) writing was absent within motivational-self system. Even less is known about mechanism motivational factors L2 writing. This study aims fill gap by testing mediating positive emotions (enjoyment, pride, hope) future selves (ideal self...
This report describes a new convergent, selective, and economical synthesis of DMP 777,1 ending with the coupling chiral β-lactam half molecule (1) to amine as isocyanate (2). Other steps involve 3 phenolic moiety under phase-transfer conditions, followed by resolution resulting piperazine derivative using acid, recycling undesired enantiomer also conditions. The 4 was produced efficiently starting from (R)-α-methylbenzylamine corresponding butyrophenone.
Background The relationship between human serum albumin levels and the prognosis of critical care patients with chronic obstructive pulmonary disease (COPD) remains controversial. Objective To investigate in-hospital mortality in COPD. METHODS: This study used a retrospective observational cohort from Medical Information Intensive Care database (MIMIC-IV) United States. Multivariate Cox regression analysis was to assess mortality. A restricted cubic spline line also explore nonlinear...
A new alkaloid, N-allylnorgalanthamine (1), was isolated from the bulbs of Lycoris guangxiensis Y. Hsu et Q. J. Fan (Amaryllidaceae). Additionally, seven known alkaloids, lycorine, narwedine, galanthamine, lycoramine, crinine, norgalanthamine, and pseudolycorine were also obtained. The structure 1 established through interpretation spectral data.
Clothing analysis has garnered significant attention, and within this field, clothing classification plays a vital role as one of the fundamental technologies. Due to inherent complexity scenes in real-world environments, learning features such complex often encounters interference. Because relies on contour texture information clothing, real may lead poor results. Therefore, paper proposes network based frequency-spatial domain conversion. The proposed combines frequency with spatial does...
<p>This article performs an exploratory study of the newly formulated <em><em>Guidelines</em></em><em> for College English Teaching </em><em>(Draft Exposure)(2015)</em>(<em>Guidelines</em>), aiming at exploring how different latest <em>Guidelines</em> is from previous ones, what challenges it brings to teachers and these can be countered. Therefore, comparisons are made among six syllabi illustrate developments...
A facile detrifluoromethylation was observed when 4,4-bis(trifluoromethyl)-5-hydroxyimidazoline 5 treated with a variety of bases to afford the biologically interesting 4-(trifluoromethyl)imidazole analogs (9 and 10). unique mechanism proposed for this transformation, supported by isolating trapping hypothesized intermediates. Heating Et(4)NCN in DMSO provided 19, which clearly derived from intermediate 17. Finally, imidazole 9 converted into...
This action research was conducted to investigate the efficacy of networking, an adjusted cooperative learning method employed in English literature class for non-English majors China. Questionnaire administered online anonymously college students after a 14-week Chinese university, aiming study whether proposed effective and how it would impact students. The results indicated that instructional practice with benefits academic study, accountability social skills.
Two new a l k o i d s , 6d/6f-hydmxy-34-methylepimaritidine (3-epipapyramine) (4 and 2 ) were t e from h bulbs of Narcissus -L.var.chinensis Roem.together with four known alkaloids, maritidine, 34-methylmaritidine, epigalanthamine lycoramine.
In recent years, the online selection of virtual clothing styles has been used to explore and expand diversified personal aesthetics, it is also an overall reform challenge industry. Under condition existing style categories, this paper puts forward a classification method combining fine-grained coarse-grained techniques. Furthermore, new deep neural network proposed, which can improve robustness recognition avoid interference image background through pan learning features. order study...
