Regarding the Regulatory Sandbox Route and Mechanism for Governance of Artificial Intelligence

The main challenge in AI governance today is striking a balance between controlling AI dangers and fostering AI innovation.Regulators in a number of nations have progressively extended the regulatory sandbox,which was first implemented in the banking sector,to AI governance in an effort to reduce the conflict between regulation and innovation.The AI regulatory sandbox is a new and feasible route for AI governance in China that not only helps to manage the risks of technology application but also prevents inhibiting AI innovation.It keeps inventors'trial-and-error tolerance space inside the regulatory purview while offering a controlled setting for the development and testing of novel AI that hasn't yet been put on the market.By providing full-cycle governance of AI with the principles of agility and inclusive prudence,the regulatory sandbox offers an alternative to the conventional top-down hard regulation,expost regulation,and tight regulation.However,the current system also has inherent limitations and practical obstacles that need to be overcome by a more rational and effective approach.To achieve its positive impact on AI governance,the AI regulatory sandbox system should build and improve the access and exit mechanism,the coordination mechanism between the sandbox and personal information protection,and the mechanisms of exemption,disclosure,and communication.

Management of chronic heart failure in the older population

Chronic heart failure （CHF） is the leading cause of hospitalization for those over the age of 65 and represents a significant clinical and economic burden. About half of hospital re-admissions are related to co-morbidities, polypharmacy and disabilities associated with CHF. Moreover, CHF also has an enormous cost in terms of poor prognosis with an average one year mortality of 33%–35%. While more than half of patients with CHF are over 75 years, most clinical trials have included younger patients with a mean age of 61 years. Inadequate data makes treatment decisions challenging for the providers. Older CHF patients are more often female, have less cardiovascular diseases and associated risk factors, but higher rates of non-cardiovascular conditions and diastolic dysfunction. The prevalence of CHF with reduced ejection fraction, ischemic heart disease, and its risk factors declines with age, whereas the prevalence of non-cardiac co-morbidities, such as chronic renal failure, dementia, anemia and malignancy increases with age. Diabetes and hypertension are among the strongest risk factors as predictors of CHF particularly among women with coronary heart disease. This review paper will focus on the specific consideration for CHF assessment in the older population. Management strategies will be reviewed, including non-pharmacologic, pharmacologic, quality care indicators, quality improvement in care transition and lastly, end-of-life issues. Palliative care should be an integral part of an interdiscipli-nary team approach for a comprehensive care plan over the whole disease trajectory. In addition, frailty contributes valuable prognostic in-sight incremental to existing risk models and assists clinicians in defining optimal care pathways for their patients.

Laryngo-tracheobronchial Amyloidosis:a Case Report and Review of Literature

AMYLOIDOSIS is a benign process which can have systemic involvement. Though larynx is the common site of localized amyloidosis in the head and neck region,I it was seldom reported with heterochronous implication of bilateral ventricles. Here we report a case of laryngeal amyloidosis heterochronously localized at bilateral ventricles with tracheobronchial involvement. Combined with our experience we reviewed the literature, and discuss the pertinent managements of this condition.

Histopathological Study on Chickens Artificially Infected with Infectious Laryngotracheitis

[Objective] This study aimed to investigate the histopathological changes in chickens artificially infected with infectious laryngotracheitis（ILT）. [Method] Through ar- tificial injection of allantoic liquid containing ILTV into chickens to induce infectious laryngotracheitis, the clinical symptoms in infected chickens were observed; tissues of trachea, lungs, heart, liver, kidney and spleen were collected from dead chickens, and prepared into paraffin sections, followed by histopathological observation under a microscope. [Results] This disease occured in the inoculated chickens 3d later, with a morbidity rate of 95%. The main symptoms were dyspnea, asthma and coughing up of bloody exudate; yellowish-white pseudomembrane was observed on dissected larynx trachea; swelling, haemorrhage, and further erosion were observed on the in- fected tracheal mucosa, resulting in death of chickens, with the mortality rate of 25%; histopathological observation showed that parenchymal organs exhibited exuda- tive inflammation; swelling, degeneration, necrosis and shedding of epithelial cells were observed; disturbance of blood circulation occured.[Conclusion] This study pro- vides reference bases for the treatment of ILT.

Land Use and Soil Organic Carbon in China’s Village Landscapes

Village landscapes, which integrate small-scMe agriculture with housing, forestry, and a host of other land use practices, cover more than 2 million square kilometers across China. Village lands tend to be managed at very fine spatial scales （≤ 30 m）, with managers both adapting their practices to existing variation in soils and terrain （e.g., fertile plains vs. infertile slopes） and also altering soil fertility and even terrain by terracing, irrigation, fertilizing, and other land use practices. Relationships between fine-scale land management patterns and soil organic carbon （SOC） in the top 30 cm of village soils were studied by sampling soils within fine-scale landscape features using a regionally weighted landscape sampling design across five environmentally distinct sites in China. SOC stocks across China＇s village regions （5 Pg C in the top 30 cm of 2 ×10^6 km^2） represent roughly 4% of the total SOC stocks in global croplands. Although macroclimate varied from temperate to tropical in this study, SOC density did not vary significantly with climate, though it was negatively correlated with regional mean elevation. The highest SOC densities within landscapes were found in agricultural lands, especially paddy, the lowest SOC densities were found in nonproductive lands, and forest lands tended toward moderate SOC densities. Bue to the high SOC densities of agricultural lands and their predominance in village landscapes, most village SOC was found in agricultural land, except in the tropical hilly region, where forestry accounted for about 45% of the SOC stocks. A surprisingly large portion of village SOC was associated with built structures and with the disturbed lands surrounding these structures, ranging from 〉 18% in the North China Plain to about 9% in the tropical hilly region. These results confirmed that local land use practices, combined with local and regional variation in terrain, were associated with most of the SOC variation within and across China＇s village landscapes and may be an important cause of regional variation in SOC.

No evidence demonstrating hepatotoxicity associated with hydroxycitric acid

Although a number of cases of hepatotoxicity are associated with the use of Hydroxycut weight management products, it has been alleged that their effects are primarily due to the presence of hydroxycitric acid (HCA, as Super CitriMax) in the formulations. However, while these products contain up to 20 different ingredients, some do not contain HCA. Case studies reported to date have not considered in depth the literature on the numerous animal and human studies that have been conducted on the safety and effi cacy of HCA. No HCA-associated hepatotoxicity or treatment-related adverse effects have been reported in these studies, and thus it is premature to make the assumptions presented in the recent case studies regarding Hydroxycut. If it is established in well controlled studies that the use of these formulations with and/or without HCA can result in the occurrence or progression of hepatotoxicity, additional studies should be conducted to characterize the causative factor(s).

Accurate Classification of P2P Traffic by Clustering Flows

P2P traffic has always been a dominant portion of Internet traffic since its emergence in the late 1990s. The method used to accurately classify P2P traffic remains a key problem for Internet Service Producers （ISPs） and network managers. This paper proposes a novel approach to the accurate classification of P2P traffic at a fine-grained level, which depends solely on the number of special flows during small time intervals. These special flows, named Clustering Flows （CFs）, are de- fined as the most frequent and steady flows generated by P2P applications. Hence we are able to classify P2P applications by detecting tlle appearance of corresponding CFs. Com- pared to existing approaches, our classifier can realise high classification accuracy by ex- ploiting only several generic properties of flows, instead of extracting sophisticated fea- tures from host behaviours or transport layer data. We validate our framework on a large set of P2P traffic traces using a Support Vector Machine （SVM）. Experimental results show that our approach correctly classifies P2P ap- plications with an average true positive rate of above 98% and a negligible false positive rate of about 0.01%.

A Master-Slave Blockchain Paradigm and Application in Digital Rights Management

Topical negative pressure in managing severe peritonitis: A positive contribution?

AIM： To assess the use of topical negative pressure （TNP） in the management of severe peritonitis. METHODS： This is a four-year prospective analysis from January 2005 to December 2008 of 20 patients requiring TNP following laparotomy for severe peritonitis. RESULTS： There were 11 males with an average age of （59.3 ± 3.95） years. Nine had a perforated viscus, five had anastomotic leaks, three had iatrogenic bowel injury, and a further three had severe pelvic inflammatory disease. TNP and the VAC Abdominal Dressing System were initially used. These were changed every two to three days. Abdominal closure was achieved in 15/20 patients within 4.53 ± 1.64 d. One patient required relaparotomy due to residual sepsis. Two patients with severe faecal peritonitis due to perforated diverticular disease received primary anastomosis at second look laparotomy, as sepsis and their general condition improved. In the remaining 5/20 cases, the abdomen was lee open due to bowel oedema and or abdominal wall oedema. Dressing was switched to TNP and VAC GranuFoam . Three of the five patients returned a few months later for abdominal wall reconstruction and restoration of intestinal continuity. Two patients developed intestinal fistulae. All 20 patients survived.CONCLUSION： The use of TNP is safe. Further studies are needed to assess its value in managing these difficult cases.

Exploring Enterprise Performance Indicators Network： A Case Study of China Telecommunication Industry

Perforrmnce indicators play some important roles in enterprise operation. Both researchers and managers have recently pointed out that the identification of correlation between different performmance indicators may lead to a better understanding of business. However, it is becoming more and more difficult to measure and analyze these indicators since the fast growing number of performance indicators and the complex relationships between them The existing categories failed to reflect these changes in an adequate way, and the quantitative analysis methods for identifying the characters of those pefformance indicators are still worthy of investigation. The main objective of this paper is to propose a practical methodology for managing and analyzing performance indicators in enterprises, which focuses on building up a performance indicator system and discovering the characters of those performance indicators by applying complex network methods. The empirical results of a telecommunieation enterprise show that the proposed method can be effective in understanding the correlations between performance indicators.

Highlights from the literature on risk assessment techniques adopted in the mining industry:A review of past contributions,recent developments and future scope

In this paper a comprehensive review is presented of risk assessment techniques adopted in the mining industry worldwide;those techniques applied in other hazardous industries and potential techniques which are robust,mature and holistic and can be implemented for the Indian mining industry in future to enhance workplace safety are also presented.Findings from the review are indicative of the fact that socio-technical complexity of industrial systems has increased.Recent developments in the area of risk management highlight the need for implementation of the latest robust techniques of risk assessment in the mining sector.In consideration of the present scenario,the development of a model for risk analysis having an interface between hazard identification and risk assessment,along with an interface between risk assessment and accident causation to predict if an accident will occur under given conditions,has become dire necessity.This will increase hazard awareness and enable mine management to select and prioritize problem areas and identify safety system weaknesses in both underground and surface mining.This will ultimately help decision makers,risk analysts and safety managers make a major contribution in the development of workplace safety with a near-to-zero accident rate.
