It is usually expected that learning performance can be improved by exploiting unlabeled data, particularly when the number of labeled data limited. However, it has been reported that, in some cases existing semi-supervised approaches perform even worse than supervised ones which only use data. For this reason, desirable to develop safe will not significantly reduce are used. This paper focuses on improving safeness support vector machines (S3VMs). First, S3VM-us approach proposed. employs a...

Deep learning technology have been broadly used in segmentation tasks of liver. To address the limitation suboptimal for small targets, an end-to-end EAS(ECA-Attention and Separable convolution) U-Net is proposed based on deep learning. The basic module employs depthwise separable convolutional modules instead to reduce parameters count enhance extraction deep-layer information. pyramid Efficient Channel Attention (ECA) utilized obtain different receptive fields. And that model can overcome...

Numerous studies have been conducted on current distribution and future changes of habitats by researchers from a range disciplines such as ecology, biology, geography, environmental science, agricultural among others. However, there is lack detailed historical spatiotemporal dynamics habitat, which can provide useful information for the conservation management endangered species habitats. Thus, we proposed an integrated framework to assess habitat across space time, well analyze driving...

ABSTRACTThere has been a long-standing discourse about science-driven practice, and related, the scientist practitioner, spanning more than 40 years. The International Society of Sport Psychology is devoting considerable attention to practitioners within recently established Registry (ISSP-R) Supervisor (ISSP-S) designations. ISSP seeks expand this discussion by (a) synthesising literature, (b) adopting geographically expansive outlook towards practitioner knowledge. This position stand...

In many real applications, especially those involving data objects with complicated semantics, it is generally desirable to discover the relation between patterns in input space and labels corresponding different semantics output space. This task becomes feasible MIML (Multi-Instance Multi-Label learning), a recently developed learning framework, where each object represented by multiple instances allowed be associated simultaneously. this paper, we propose KISAR, an algorithm that able what...

The Yancheng coastal wetlands serve as a crucial stopover site along the East Asian–Australasian Flyway. rapid expansion of aquaculture has led to significant decline in natural wetlands, impacting both distribution and quality waterbird habitats. Following designation region World Natural Heritage 2019, local government prioritized protection habitats, leading large-scale withdrawal from region. Nevertheless, impact fishing on habitat selection ecological benefits it brought remain unknown....

The purpose of this research was to explore 14 elite refugee athletes' experiences transitioning the Canadian sports system and examine social contexts that enabled constrained meaning, a psychological mechanism facilitates adaptive cultural transitions. Framed within critical realism, arts-based conversational interviews were undertaken with athletes. Through reflexive thematic analysis Viktor Frankl's theory four themes (feelings hope empowerment, environmental challenges adaptations,...

Growing pathways exist for forced migrant elite athletes to continue sport within host countries' sports systems following migrations. These provide relocation opportunities but remain limited in supporting these athletes' cultural transitions and integration post-settlement. Drawing on a funded project conducted with 14 athletes, the purpose of this manuscript was translate empirical findings into recommendations SPPs support adaptation needs. We first introduce how guided tours facilitate...

The aim through this manuscript is to share our career intervention situated in individual, group, and meta-reflective practice, help elite athletes manage changes their careers support autonomy development within the Chinese Whole Nation System (CWNS). Translating findings from a science practice project, we provide an athlete-centered reflective integrating perspectives of sport psychology practitioners (SPPs), coaches, athletes, parents collective vantage. First, introduce how athlete...

Efficient RNA isolation is a prerequisite to elucidate the molecular mechanisms of peimine metabolism in medicinal plant Fritillaria unibracteata, rare and famous region drug Sichuan, China. Three different methods were tested: modified SDS acid phenol, CTAB SDS-LiCl. Compared with SDS-LiCl methods, method phenol would obtain initial, abundant high-quality intact from F. unibracteata. Meanwhile, RNA-containing bands are clear light, lightness 28S rRNA two times than 18S rRNA. The ratio...
