Unlike some block-based methods, the proposed scheme encodes the secret bits directly into boundary pixels by checking each pixel of the cover image in a pseudo-random order for embedding eligibility. A set of rules ensures correct identification of data-carrying pixels in blind extraction. The proposed scheme does not generate isolated dots, and can incorporate various coding methods such as matrix encoding to further improve the embedding performance. It is shown that up to one fourth of the boundary pixels may be used to carry secret data. Experimental results indicate that the method can achieve good visual quality with fairly large data capacity.展开更多

An agent uses a multi-agent system to cooperate with other agents to accomplish the given task, and one agent′s behavior usually affects the others′ behaviors. In traditional reinforcement learning, one agent takes the others location, so it is difficult to consider the others′ behavior, which decreases the learning efficiency. This paper proposes multi-agent reinforcement learning with cooperation based on eligibility traces, i.e. one agent estimates the other agent′s behavior with the other agent′s eligibility traces. The results of this simulation prove the validity of the proposed learning method.展开更多

The eligibility ...Introduction: Limited access to treatment is a crucial factor contributing to the suboptimal control of hepatitis B virus (HBV) infection, especially in sub-Saharan African countries such as Tanzania. The eligibility for antiviral therapy is typically determined based on the extent of HBV replication and liver damage. However, there is insufficient data available regarding the actual treatment needs and the overall characteristics of HBV-infected individuals in Tanzania. Therefore, the aim of this study is to fill this knowledge gap and provide valuable insights to aid in the planning of treatment programs. Materials and Methods: We conducted a cross-sectional study at Bugando Medical Centre in northwest Tanzania, examining the data of 340 patients who were diagnosed with chronic HBV infection and attending the hepatitis clinic. Data on sociodemographic, clinical, and investigation details were collected through electronic files and subsequently analyzed. The eligibility for HBV antiviral treatment was assessed using the criteria established by the World Health Organization (WHO). Results: Out of the 340 patients included in the study, the majorities were males 252 (74.1%) and had a median age of 36 years. Most patients came from outside of Mwanza city. Twenty-percent had significantly elevated alanine transaminase, and over one-third had high DNA levels (>2000 IU/L). The prevalences of liver cirrhosis and significant liver fibrosis were 15% and 15.3%, respectively. None of the patients were on antiviral therapy for hepatitis B. A total of 64 (18.8%) patients met the criteria for treatment eligibility. Male sex, older age, residing outside Mwanza city, and anemia (all with p Conclusion and Recommendations: The significant number of HBV-infected patients is suitable for antiviral therapy but none of them have initiated the treatment. The significance of these findings is to emphasize the need for enhancing hepatitis B services in Tanzania.展开更多

Nonetheless, the IP associated with AI remains still barely covered in scientific publications. Especially patent discussion tends to be rather a legal matter. Another trilogy, 2013, “Business Strategy-IP Strategy-R&D Strategy: An All-in-One Business Model” proposed by the author, marked the advent, and customized implementation of a new strategy level. After the two trilogies’ volumes, the AI-IP “accessibility” chapter was a logical step brought to the attention of a larger public by the author. The time now to bring to light another chapter, namely the IP eligibility of AI innovation steps in ad hoc inventions. The main objectives of this short, principally illustrated communication, are to: 1) Revise the best mode requirement status, i.e. the best way to enable the reproducibility of claimed matter, reviewing its need for improvement when AI is involved. And proposing a unique sequence of evolution inspired by IP’s current and evolving practices. 2) Give a new dimension to visual aids to help the Best Mode description, demystify AI complexity, and underline frontier traits that may hinder a confident adoption or well-argued rejection. 3) Further illustrations take into account the fact that IoT, AI, and 3D can be simpler than perceived. 4) Finally ATA©, Adjacent Technology Analysis, is timely refreshed in a unique challenging, indeed tumultuous, environment. 5) Bias, such as semantic ones is consistently monitored. 6) Overall leaving space for innovative pleasurable interpretation.

To allow more patients to be transplanted before they die on the waitlist an increase in the number of donors is necessary. Patients with devastating irreversible brain injury, if medically suitable, are potential deceased donors and strategies are needed to successfully convert them into actual donors. Multiple steps in the process of deceased organ donation can be targeted to increase the number of organs suitable for transplant. In this review, after describing this process, we discuss current challenges and potential strategies to expand the pool of deceased donors.展开更多

文摘We present a novel scheme for embedding secret data into a binary image without introducing noticeable artifacts. Unlike some block-based methods, the proposed scheme encodes the secret bits directly into boundary pixels by checking each pixel of the cover image in a pseudo-random order for embedding eligibility. A set of rules ensures correct identification of data-carrying pixels in blind extraction. The proposed scheme does not generate isolated dots, and can incorporate various coding methods such as matrix encoding to further improve the embedding performance. It is shown that up to one fourth of the boundary pixels may be used to carry secret data. Experimental results indicate that the method can achieve good visual quality with fairly large data capacity.
