Progress in Investigating the Current Mental Health Status Among Caregivers for Surgical Oncology Patients

This article aims to discuss the current state and research progress concerning the mental health of caregivers for surgical oncology patients.The goal is to offer insights that can serve as a reference for further enhancements in caregivers’mental well-being.This article conducts a comprehensive review and analysis of recent studies on the mental health of caregivers for patients undergoing oncologic surgery.These studies reveal that caregivers commonly grapple with mental health issues,including anxiety,depression,and stress.These problems are closely linked to the stress of the patient’s condition and treatment,the caregiver’s own mental strain,and a lack of social support.In addition,the mental health status of caregivers significantly influences the patient’s treatment and recovery process.Implementing various interventions,such as mental health education,services,the establishment of mental health support teams,and engagement in mental health promotion activities,can contribute to the improvement of caregivers’mental well-being.This,in turn,has the potential to enhance treatment outcomes and the overall quality of life for patients.

Theory of the Solution of Inventive Problems (TRIZ) and Computer Aided Design (CAD) for Micro-electro-mechanical Systems (MEMS)

Satellite remote sensing technology[1] is widely used in all walks of life ,which plays an increasingly remarkable results in natural disasters(sudden and major).With more and more launch and application of high resolution satellite, the texture information in remote sensing imagery becomes much more abundant. In the age of big data, for the infrared remote sensor has short life, which annoys many people. In the packaging process, due to a difference in thermal expansion coefficients [2] between the flip-chip bonded MEMS device and the substrate, cooling after bonding can cause the MEMS to buckle. Combine TAIZ theory with the flexure design in CAD to solve the problem. It can be obtained that increasing fold length can reduce warpage. By solving the deformation problem of MEMS devices can facilitate the development of flip chip technology, and make for the further application of the TRIZ theory in the study of remote sensing equipment.

Knowledge Acquisition from Forestry Machinery Patent Based on the Algorithm for Closed Weighted Pattern Mining

The application of big data mining can create over a trillion dollars value. Patents contain a great deal of new technologies and new methods which have unique value in the product innovation. In order to improve the effectiveness of big data mining and aid the innovation of products of forestry machinery, the algorithm for closed weighted pattern mining is applied to acquire the function knowledge in the patents of forestry machinery.

The novel transmission scheme with CAT Ethernet cable and SFP for White Rabbit

Background White Rabbit(WR)is a deterministic Ethernet-based network for general-purpose data transfer and subnanosecond time synchronization in large distributed systems.WR has been used in Large Hadron Collider and Large High-Altitude Air Shower Observatory for physics experiment.Purpose WR mainly uses the optical fiber for data transmission between WR devices.Commercial off-the-shelf Direct Attach Cable is not suitable for WR network at 100m level distance.Considering the lower cost of Category(CAT)Ethernet cable compared to optical fiber and the demand of remote power supply in distributed system at 100m level length,we developed a novel transmission scheme with CAT Ethernet cable for WR.Methods The novel transmission scheme uses the CAT Ethernet cable and small form-factor pluggable connector which is compatible with the optical links.This scheme only uses two pairs of twisted lines in the CAT Ethernet cable for data uplink and downlink.The other two pairs of twisted lines are used for remote power supply.Results and conclusion The novel transmission scheme could use the CAT Ethernet cable to complete remote power supply and time synchronization with expected time offset of less than 100 ps and standard deviation of less than 20 ps in the WR distributed system.The distance of distributed nodes could be 80m with one CAT 7 Ethernet cable or 150m with relay transceiver connecting two CAT 7 Ethernet cables.In the short-distance scenarios,the novel transmission scheme has lower cost than the optical fiber and additional power supply function.
