What is the shortcomings of defect engineering in TMDs? 


Best insight from top research papers

Defect engineering in TMDs has some shortcomings. The presence of structural defects inherited from both the bulk systems and the exfoliation procedures undermines the device performance . The contact resistance of TMD devices is not comparable to that of their silicon counterparts, possibly due to a lack of clarity in their interface chemistry . While defects are important for controlling the properties of TMDs, the surface defects become the dominant factor in determining material properties at the monolayer and few layer limit . Atomic defects, such as chalcogen vacancies, can significantly modulate the properties of TMDs, but controlling these defects is challenging . Despite efforts to reduce contact resistance through defect engineering, achieving the desired performance in TMD-based devices is still a challenge .

What are the common barriers to MCMD implementation in healthcare systems?5 answersCommon barriers to Multidisciplinary Care Model (MCMD) implementation in healthcare systems include technical concerns, initial and maintenance costs, security concerns, lack of technical support, user resistance, system interoperability capability, lack of infrastructures, productivity concerns. Additionally, barriers such as culture and personnel, clinical utility of the PM and ML tool, financing, technology, and data have been identified in the adoption and implementation of predictive modeling and machine learning (PM and ML) in clinical care. Furthermore, a lack of time, financial problems, lack of specialized personnel, lack of clarity, and lack of credibility in the evidence are barriers to the implementation of Clinical Practice Guidelines (CPGs). Understanding and addressing these barriers are crucial for successful implementation of MCMD in healthcare systems.
What are the limitations (disadvantages) of Total Productive Maintenance (TPM)?5 answersTotal Productive Maintenance (TPM) faces limitations despite its benefits. One major limitation is the difficulty in adopting TPM due to challenges in the planning phase, which can hinder successful implementation. Additionally, some companies struggle to achieve the desired Overall Equipment Effectiveness (OEE) levels, falling below the JIPM standard of 85%, leading to suboptimal performance and productivity. Moreover, TPM implementation may not always directly correlate with guest satisfaction in the hospitality industry, highlighting a potential disconnect between TPM adoption and customer-related outcomes. These limitations underscore the importance of addressing planning challenges, improving OEE levels, and considering broader impacts beyond operational efficiency when implementing TPM.
What is the problem of slp dswd progra?5 answersThe Sustainable Livelihood Program (SLP) implemented by the Department of Social Welfare and Development (DSWD) faces several challenges. These include issues with beneficiary targeting, delays in project review and approval, and the perception that the establishment of SLP associations hinders success rather than facilitating it. In the context of Digital Signal Processing (DSP), the specialized functions of DSP frames pose obstacles to SIMD auto-vectorization, impacting the compiler's ability to support this feature effectively. Additionally, traditional SVDD algorithms often face limitations in training sample numbers, leading to insufficient accuracy in defining sample regions and requiring extensive data processing. In Software-Defined Networking (SDN), the increasing number of switches results in more faults in the data plane, with current fault detection mechanisms being inefficient for large-scale SDN environments.
What are the main limitations of technical innovation systems?5 answersThe main limitations of technical innovation systems include a lack of understanding of the underlying mechanisms of certain functions, such as entrepreneurial experimentation, market formation, and development of positive externalities. There is also a need for more qualitative analysis to identify causal chains of events within these systems. The functions framework is not easily applicable to pure diffusion contexts, suggesting the need for a diffusion system framework to supplement the technological innovation system framework. Another limitation is the bias towards formalization of management in traditional socio-technical systems, which depersonalizes individuals and hampers innovative development. The technical innovation of service industries must meet certain conditions, such as promoting other industries, adapting to the natural and social environment, and being original, in order to contribute to the formation of a modern industrial system. Additionally, the insufficient innovative motivation of small and medium enterprises (SMEs) due to the absence or imperfection of a corresponding incentive system is a fundamental reason for the inadequate power of technical innovation in SMEs.
What are the limitations of using S-D logic?5 answersThe limitations of using S-D logic are that it provides a simplified model of the world and does not consider the complex nature of services, which involve an exchange of psychological satisfaction and emotions alongside the actual exchange of objects, acts, and money. Additionally, there are severe problems with first-order logic, which is a major component of intelligent agents, leading to the use of different formalisms in successful AI applications.
What are the specific problems that have been found with total knee replacement products?4 answersTotal knee replacement products have been found to have several specific problems. One problem is the need for accurate determination of the position and angle of a distal bone cut surface during knee replacement surgery. Another problem is the time and labor required for installing the tibial insert trial in a patient. Additionally, there is a need to stabilize the attitude of a movable-side member without influencing the shape of a sliding surface of a femoral component in a tibia trial for total knee replacement. Furthermore, there is a need for a method and device to manufacture a total knee replacement digital osteotomy guiding plate that is both customized and precise. Lastly, there is a need for a total knee replacement digital incisive bone guiding plate that can accurately position on the femur, even in the presence of bone spurs.
