Infertility can be stressful for infertile couples. This study aims to examine the intra‐dyadic associations between stigma, communication patterns, and infertility‐related stress in couples undergoing artificial insemination by donor semen (AID). This cross‐sectional study was conducted from January to April 2021. Two hundred and three couples undergoing AID were recruited from a reproductive centre in China. All of the couples completed a two‐item stigma questionnaire, Communication Pattern Questionnaire, and Fertility Problem Inventory. The actor‐partner interdependence mediation analysis was performed using AMOS 23.0. The analysis demonstrated significant actor–actor effects for couples undergoing AID. More specifically, higher levels of stigma among wives and husbands were associated with more negative communication patterns, thereby increasing their own infertility‐related stress. Simultaneously, there was a significant partner–actor effect among infertile wives, demonstrating that the husband's stigma can affect his wife's infertility‐related stress by influencing her communication patterns. Couples undergoing AID experience increased infertility‐related stress when they have high levels of stigma and negative communication patterns, and husbands' stigma is correlated to wives' communication patterns. Therefore, dyadic interventions aiming to improving stigma and enhancing positive communication may be conducive to reducing infertility‐related stress. [ABSTRACT FROM AUTHOR]

This study aims to explore the change of intimate relationship between people with Alzheimer's disease and their adult child caregivers as the disease progresses. Twelve adult child caregivers were recruited through purposive sampling. Explanatory phenomenological analysis was conducted to analyse data collected by semi-structured in-depth interviews. This study found a dynamically changing relationship between adult child caregivers and their parents with Alzheimer's disease during care giving that evolved with the progress of the disease. The relationship was the most intimate in the middle stage of the disease for most caregivers and a new reciprocal relationship developed due to caregiving. Caregivers experienced different degrees of self-growth when providing care, though caregiver burdens were common. The positive experience and perception of caregivers were important for improving the quality of life for adult child caregivers of people with Alzheimer's disease. [ABSTRACT FROM AUTHOR]

Water extraction from synthetic aperture radar (SAR) images has an important application value in wetland monitoring, flood monitoring, etc. However, it still faces the problems of low generalization, weak extraction ability of detailed information, and weak suppression of background noises. Therefore, a new framework, Multi-scale Attention Detailed Feature fusion Network (MADF-Net), is proposed in this paper. It comprises an encoder and a decoder. In the encoder, ResNet101 is used as a solid backbone network to capture four feature levels at different depths, and then the proposed Deep Pyramid Pool (DAPP) module is used to perform multi-scale pooling operations, which ensure that key water features can be captured even in complex backgrounds. In the decoder, a Channel Spatial Attention Module (CSAM) is proposed, which focuses on feature areas that are critical for the identification of water edges by fusing attention weights in channel and spatial dimensions. Finally, the high-level semantic information is effectively fused with the low-level edge features to achieve the final water detection results. In the experiment, Sentinel-1 SAR images of three scenes with different characteristics and scales of water body are used. The PA and IoU of water extraction by MADF-Net can reach 92.77% and 89.03%, respectively, which obviously outperform several other networks. MADF-Net carries out water extraction with high precision from SAR images with different backgrounds, which could also be used for the segmentation and classification of other tasks from SAR images.

As the oil field enters the medium and high water cut stage, the difficulty of the measures to explore the potential is increasing, the geological conditions of new production wells are getting worse, it is more and more difficult to select wells and layers, and the effect of oil increase is gradually getting worse. In order to improve the effect of oil increase, it is necessary to refine the measures to explore the potential, expand the space of well and layer selection, and optimize the fracturing process. Therefore, we drew on the successful experience of small fracture network fracturing in T oilfield, selected six straight wells for fracturing of small fracture network in the P reservoir of the S oil field, expanded the oil discharge area, raised the seepage capacity of reservoir, and improved the development effect.
