TL;DR: The paper-based humidity sensor has good flexibility and compatibility, endowing it with multifunctional applications for breath rate, baby diaper wetting, noncontact switch, skin humidity, and spatial localization monitoring.
Abstract: Developing a facile, cost-saving, and environment-friendly method for fabricating a multifunctional humidity sensor is of great significance to expand its practical applications. However, most humidity sensors involve a complex fabrication process, resulting in their high cost and narrow application fields. Herein, a multifunctional paper-based humidity sensor with many advantages is proposed. This humidity sensor is fabricated using conventional printing paper and flexible conductive adhesive tape by a facile pasting method, in which the paper is used as both the humidity-sensing material and the substrate of the sensor. Owing to the moderate hydrophilicity of the paper and the rational structure design of the paper-based humidity sensor, the sensor exhibits an excellent humidity-sensing response of more than 103 as well as good linearity ( R2 = 0.9549) within the humidity range from 41.1 to 91.5% relative humidity. Furthermore, the paper-based humidity sensor has good flexibility and compatibility, endowing it with multifunctional applications for breath rate, baby diaper wetting, noncontact switch, skin humidity, and spatial localization monitoring. Although the resistance of the paper-based humidity sensor is relatively large, the humidity-sensing response signals of the sensor can be conveniently processed by the designed signal processing system. The readily available starting materials and facile fabrication technique provide useful strategies for the development of multifunctional humidity sensors.

TL;DR: Experiments show that the proposed DAPN method can detect multi-scale ships in different scenes of SAR images with extremely high accuracy and outperforms other ship detection methods implemented on SSDD.
Abstract: Synthetic aperture radar (SAR) is an active microwave imaging sensor with the capability of working in all-weather, all-day to provide high-resolution SAR images. Recently, SAR images have been widely used in civilian and military fields, such as ship detection. The scales of different ships vary in SAR images, especially for small-scale ships, which only occupy few pixels and have lower contrast. Compared with large-scale ships, the current ship detection methods are insensitive to small-scale ships. Therefore, the ship detection methods are facing difficulties with multi-scale ship detection in SAR images. A novel multi-scale ship detection method based on a dense attention pyramid network (DAPN) in SAR images is proposed in this paper. The DAPN adopts a pyramid structure, which densely connects convolutional block attention module (CBAM) to each concatenated feature map from top to bottom of the pyramid network. In this way, abundant features containing resolution and semantic information are extracted for multi-scale ship detection while refining concatenated feature maps to highlight salient features for specific scales by CBAM. Then, the salient features are integrated with global unblurred features to improve accuracy effectively in SAR images. Finally, the fused feature maps are fed to the detection network to obtain the final detection results. Experiments on the data set of SAR ship detection data set (SSDD) including multi-scale ships in various SAR images show that the proposed method can detect multi-scale ships in different scenes of SAR images with extremely high accuracy and outperforms other ship detection methods implemented on SSDD.

TL;DR: RSDP provides an efficient, systematic and simple approach for evaluating multistate network reliability given all d-MPs and is found that RSDP is more efficient than the existing algorithm when the number of components of a system is not too small.
Abstract: The multistate networks under consideration consist of a source node, a sink node, and some independent failure-prone components in between the nodes. The components can work at different levels of capacity. For such a network, we are interested in evaluating the probability that the flow from the source node to the sink node is equal to or greater than a demanded flow of d units. A general method for reliability evaluation of such multistate networks is using minimal path (cut) vectors. A minimal path vector to system state d is called a d-MP. Approaches for generating all d-MPs have been reported. Given that all d-MPs have been found, the issue becomes how to evaluate the probability of the union of the events that the component state vector is greater than or equal to at least one of the d-MPs. There is a need for a more efficient method of determining the probability of this union of events. In this paper, we report an efficient recursive algorithm for this union probability evaluation based on the Su...

TL;DR: UCA1 can directly interact with miR-143, lower its expression and affect its downstream regulation, which constitutes a part of the oncogenic role of UCA1 in breast cancer.
Abstract: Objective Long non coding RNA (LncRNA) urothelial carcinoma-associated 1 (UCA1) is an oncogene in breast cancer. However, the detailed mechanism has not been fully revealed. This study explored whether UCA1 can directly interact with miR-143, a tumor suppressor in breast cancer and whether the UCA1-miR-143 axis is involved in regulation of cancer cell growth and apoptosis. Patients and methods miRNA microarray was performed to identify the most dysregulated miRNAs between tumor and adjacent normal tissues of breast cancer. QRT-PCR analysis was performed to assess the expression of UCA1 and miR-143. The binding between UCA1 and miR-143 was verified using dual luciferase and RNA binding protein immunoprecipitation (RIP) assay. MTT assay and flow cytometry analysis were performed to study the role of UCA1-miR-143 axis in cell proliferation, cell cycle and apoptosis. Results UC1 was significantly upregulated, while miR-143 was significantly downregulated in the tumor tissues than in the adjacent normal tissues. There are direct interactions between miR-143 and the miRNA recognition sites of UCA1. UCA1 is present in Ago2-containing RNA-induced silencing complex (RISC), through association with miR-143. Through downregulating miR-143, UCA1 can modulate breast cancer cell growth and apoptosis. Conclusions UCA1 can directly interact with miR-143, lower its expression and affect its downstream regulation. Therefore, the UCA1-miR-143 axis constitutes a part of the oncogenic role of UCA1 in breast cancer.

TL;DR: This paper presents the vibration control design for a Euler-Bernoulli beam with the boundary output constraint, and a novel barrier Lyapunov function is employed for the control design and stability analysis.
Abstract: In this paper, we present the vibration control design for a Euler–Bernoulli beam with the boundary output constraint. To prevent the constraint violation, a novel barrier Lyapunov function is employed for the control design and stability analysis. This paper represents an important step in extending the barrier Lyapunov function theory to distributed parameter systems. Model-based barrier control is proposed to suppress the vibration of a flexible Euler–Bernoulli beam under the boundary output constraint. Then, adaptive control is designed to handle the system parametric uncertainties. The vibration suppression is well achieved without violation of the constraint. Numerical simulations are provided to illustrate the performance of the control system.
