First, a user with the maximal instantaneous channel capacity is selected to transmit its signal to the base station ( BS) in the transmission time slot. Then, when the user transmits its signal to BS, the jammer is invoked for transmitting artificial noise in order to perturb the eavesdropper’s reception. Simulation results show that increasing the number of users can enhance the SRT performance of the proposed JJUS scheme. In addition, the SRT performance of the proposed JJUS scheme is better than that of the traditional round-robin scheduling and pure user scheduling schemes. The proposed JJUS scheme can guarantee the secure transmission even in low main-to-eavesdropper ratio( MER) regions.展开更多

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).展开更多

MA has to provide information to managers and depending on the problem complexity, they have to solve problems in a dyadic way. A dual process model, the heuristic systematic model (HSM), expands this so-called manager-accountant-dyad and shows different cases of actual human information processing. Managers and accountants either process systematically or heuristically. So far, many concepts have been designed in relation to the normative concept of the economical rational principle. Consequently, recent research only uses systematic information processing, based on the principle of the economic man. In this paper, a decision-behavior oriented approach tries to describe actual decision makers such as managers and accountants and shows new possibilities within MA. Therefore, the potential of heuristic information processing is analyzed, based on the phenomenon of ecological rationality as one shape of bounded rationality. Thus, different cognitive heuristics in business economics are identified and analyzed. Furthermore, the outstanding performance of heuristics compared with more complex calculations is shown. Unfortunately, these findings have been limited to marketing and investments so far. Significant research is needed, regarding conditions for applications and success factors of heuristics in business economics. New empirical findings have to be explicitly transferred to MA.展开更多

As a leading cause of hospitalizations among patients aged 65 years or older, HF is a major consumer of healthcare resources, creating a substantial strain on the healthcare system. This paper discusses the epidemiology of HF, financial impact, and multifaceted predicaments in end-stage HF care. A search was conducted on the U.S National Library of Medicine website (www.pubmed.gov) using keywords such as end-stage heart failure, palliative care, ethical dilemmas. Despite the poor prognosis of HF (worse than that for many cancers), many HF patients, caregivers, and clinicians are unaware of the poor prognosis. In addition, the unpredictable clinical trajectory of HF complicates the planning of end-of-life care, such as palliative care and hospice, leading to underutilization of such resources. In conclusion, ethical dilemmas in end-stage HF are numerous, embroiling not only the patient, but also the caregiver, healthcare team, and society.展开更多

The epidemiology and pathophysiology of frailty share features with those of cardiovascular disease. Gait speed can be used as a measure of frailty and is a powerful predictor of mortality. Advancing age is a potent risk factor for cardiovascular disease and has been associated with an increased risk of adverse outcomes. Older adults comprise approximately half of cardiac surgery patients, and account for nearly 80% of the major complications and deaths following surgery. The ability of traditional risk models to predict mortality and major morbidity in older patients being considered for cardiac surgery may improve if frailty, as measured by gait speed, is included in their assessment. It is possible that in the future frailty assessment may assist in choosing among therapies (e.g., surgical vs. percutaneous aortic valve replacement for patients with aortic stenosis).展开更多

The results obtained show that physicomechanical properties of the harvested fruits had an effect on the use of robotic systems. Parameters such as weight, height, width, thickness and surface area were identified as the main effect in robotic fruit harvesting. Image processing techniques also had direct effect on robotic systems operation which therefore requires careful selection procedure to achieve results accuracy. It was observed that the C# programming language used in robotic systems fruit harvesting should be parallel with the image processing to ensure accurate conversion of kinematic calculation, system input parameters and constant values. The use of hobby-type parts of a robot in the prototype study showed reliable results. However, to ensure functionality of the robotic systems application, industrial robots and servo engines should be used. It was also observed that the use of a gripper for picking the fruits from the branch must The engines that make the system work should be strong and the be made considering the physicomechanical properties of the fruit. cutting system should also be appropriate.展开更多

Preclinical data have suggested synergy between capecitabine and temozolomide(CAPTEM). Therefore, we evaluated the efficacy and safety of CAPTEM in patients with metastatic NECs who have failed prior therapies.Methods A retrospective review was conducted on seven patients with metastatic NECs for whom platinum-based chemotherapies and hepatic chemoembolization failed. Patients received capecitabine(1000 mg twice daily on days 1-14) and temozolomide(150–200 mg/m^2 once daily on days 10–14) every 28 days. Tumor assessments were performed every two cycles.Results Among the seven patients treated, two achieved partial remission and four achieved stable disease. The total response rate was 29%, and the clinical benefit was 86%. Median progression-free survival was 10(range: 8–14) months. The most common toxicities were grade 1 and 2 neutropenia, grade 1 fatigue, and grade 1 and 2 hand-foot syndrome. No grade 4 toxicities or treatment-related deaths were observed.Conclusion Our study showed that the CAPTEM regimen is an effective and well-tolerated salvage option for NECs. Further prospective studies are warranted to evaluate optimal combinations of the CAPTEM regimen for NECs.展开更多

This work presents an equipment selection knowledge base system for industrial styrene process(S-ESKBS) based on the ontology technology. This structure includes a low-level knowledge base and a top-level interactive application. As the core part of the S-ESKBS, the low-level knowledge base consists of the equipment selection ontology library, equipment selection rule set and Pellet inference engine. The top-level interactive application is implemented using S-ESKBS, including the parsing storage layer, inference query layer and client application layer. Case studies for the industrial styrene process equipment selection of an analytical column and an alkylation reactor are demonstrated to show the characteristics and implementability of the S-ESKBS.展开更多

Versatility can be generally defined as a mastery of opposites, as the ability to play multiple roles, even contradictory ones, without emphasizing some at the expense of others. The LVI has been designed to help managers understand their repertoire and how they can become more versatile leaders. It employs an innovative rating scale on which ideal score "0" is in the middle of it (the right amount), flanked by underdoing to the left (too little) and overdoing to the right (too much). The idea is to avoid the "more is better" design trap by providing a way for raters to indicate when managers go to counterproductive extremes. The LVI works with two-sided view of leadership based on two major pairs of opposites: directive vs. supportive leadership and execution vs. strategy. Interventions based on the LVI results help to overcome traditional behaviorism as they combine the outer work (behavioral change) with the inner work (personal change) of development. Application of the LV1 on a sample of the managers from Skoda Auto a.s. and verification of its practical value represented the core of the SAVS IGA project MM/O7/02. The last part of the paper is devoted to a presentation of the findings from this project. The LVI has been found to be both original and a very useful 360 feedback tool which can be addressed to two general groups of clients: (1) experienced senior managers; and (2) young perspective managers in the beginning of their career.展开更多

The principle of respect for human dignity is a universal moral concept, meant to be applied in human encounters. Protecting human rights underscores the legal principle of not only affirming the fundamental equality of all human beings, but equally safeguarding it. These two principles are universally defined, but are ordinarily specified by the particular value system of individual cultures in which they are employed. It is within such particular cultural application that their relevance stands out. The thrust of this paper is that, since principles are general action guides, they actually constitute a universal language for the analysis and evaluation of all human conduct. However, there is also recognition of the fact that moral contexts vary from culture to culture, and that while the scope of the two principles above is not restricted by any particular culture, it is indeed those cultural specifics of each moral context that constitute the framework within which the principles become operational. As general action guides, I will argue that these principles lack moral relevance outside of those particular cultural settings wherein they are contextualized. Without such relevance, these principles become meaningless mantras. I will further show that such principles do not merely uphold values informed by particular cultures, but they are an embodiment of values inherent to human nature in general. Consequently, these principles do not just serve as instruments for addressing issues peculiar to "Western bioethics" or any other particular cultural setting in an exclusive sense, but are also used for moderating bioethics discourse that transcend particular cultural boundaries. I will further explain that such universal discourse is potentially instructive with regards to how cultural universals are viewed in relation to the cultural particulars, and that this discourse essentially becomes a lingua franca for cross-cultural dialogue in bioethics.展开更多

文摘AIM:To investigate health-related quality of life(HRQoL) and psychological outcomes in 256 adults who had undergone liver transplantation(LT).METHODS:A stratified random sampling method was used in this follow-up multicenter study to select a representative sample of recipients undergoing either living donor liver transplantation(LDLT) or deceased donor liver transplantation(DDLT).HRQoL was measured by using the Chinese version of Medical Outcome Study Short Form-36(SF-36),and psychological outcomes by using the beck anxiety inventory(BAI) and the self-rating depression scale(SDS).Clinical and demographic data were collected from the records of the Chinese Liver Transplant Registry and via questionnaires.RESULTS:A total of 256 patients were sampled,including 66(25.8%) receiving LDLT and 190(74.2%) undergoing DDLT;15(5.9%) recipients had anxiety and four(1.6%) developed severe depression after the operation.Compared with LDLT recipients,DDLT patients had higher scores in general health(60.33 ± 16.97 vs 66.86 ± 18.42,P = 0.012),role-physical(63.64 ± 42.55 vs 74.47 ± 36.46,P = 0.048),roleemotional(61.11 ± 44.37 vs 78.95 ± 34.31,P = 0.001),social functioning(78.60 ± 22.76 vs 88.16 ± 21.85,P = 0.003),vitality(70.30 ± 15.76 vs 75.95 ± 16.40,P = 0.016),mental health(65.88 ± 12.94 vs 71.85 ± 15.45,P = 0.005),physical component summary scale(PCS,60.07 ± 7.36 vs 62.58 ± 6.88,P = 0.013) and mental component summary scale(MCS,52.65 ± 7.66 vs 55.95 ± 10.14,P = 0.016).Recipients > 45 years old at the time of transplant scored higher in vitality(77.33 ± 15.64 vs 72.52 ± 16.66,P = 0.020),mental health(73.64 ± 15.06 vs 68.00 ± 14.65,P = 0.003) and MCS(56.61 ± 10.00 vs 54.05 ± 9.30,P = 0.037) than those aged ≤ 45 years.MCS was poorer in recipients with than in those without complications(52.92 ± 12.21 vs 56.06 ± 8.16,P = 0.017).Regarding MCS(55.10 ± 9.66 vs 50.0 ± 10.0,P < 0.05) and PCS(61.93 ± 7.08 vs 50.0 ± 10.0,P < 0.05),recipients scored better than the Sichuan general and had improved overall QoL compared to patients with chronic diseases.MCS and PCS significantly correlated with scores of the BAI(P < 0.001) and the SDS(P < 0.001).CONCLUSION:Age > 45 years at time of transplant,DDLT,full-time working,no complications,anxiety and depression were possible factors influencing postoperative HRQoL in liver recipients.
文摘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).
文摘Classical management accounting (MA) Focusing on the facilitating perspective, focuses on decision facilitating and influencing (Demski & Feltham, 1976). MA has to provide information to managers and depending on the problem complexity, they have to solve problems in a dyadic way. A dual process model, the heuristic systematic model (HSM), expands this so-called manager-accountant-dyad and shows different cases of actual human information processing. Managers and accountants either process systematically or heuristically. So far, many concepts have been designed in relation to the normative concept of the economical rational principle. Consequently, recent research only uses systematic information processing, based on the principle of the economic man. In this paper, a decision-behavior oriented approach tries to describe actual decision makers such as managers and accountants and shows new possibilities within MA. Therefore, the potential of heuristic information processing is analyzed, based on the phenomenon of ecological rationality as one shape of bounded rationality. Thus, different cognitive heuristics in business economics are identified and analyzed. Furthermore, the outstanding performance of heuristics compared with more complex calculations is shown. Unfortunately, these findings have been limited to marketing and investments so far. Significant research is needed, regarding conditions for applications and success factors of heuristics in business economics. New empirical findings have to be explicitly transferred to MA.
文摘Heart failure (HF), a complex clinical syndrome due to structural or functional disorder of the heart, is a major global health issue, with a prevalence of over 5.8 million in the USA alone, and over 23 million worldwide. As a leading cause of hospitalizations among patients aged 65 years or older, HF is a major consumer of healthcare resources, creating a substantial strain on the healthcare system. This paper discusses the epidemiology of HF, financial impact, and multifaceted predicaments in end-stage HF care. A search was conducted on the U.S National Library of Medicine website (www.pubmed.gov) using keywords such as end-stage heart failure, palliative care, ethical dilemmas. Despite the poor prognosis of HF (worse than that for many cancers), many HF patients, caregivers, and clinicians are unaware of the poor prognosis. In addition, the unpredictable clinical trajectory of HF complicates the planning of end-of-life care, such as palliative care and hospice, leading to underutilization of such resources. In conclusion, ethical dilemmas in end-stage HF are numerous, embroiling not only the patient, but also the caregiver, healthcare team, and society.

文摘Objectives:In recent years,the use of mobile health applications(mHealth apps)to deliver care for patients with breast cancer has increased exponentially.This study aimed to summarize the available evidence on developing mHealth apps to care for patients with breast cancer and identify the need for systematic efforts.Methods:A scoping review was performed according to Arksey and O’Malley’s framework,aiming to identify eligible research studies in PubMed,CINAHL,and Web of Science between January 2010 and December 2020.All identified studies were screened,extracted,and analyzed independently by two reviewers.Results:A total of 676 studies were retrieved,and eight eligible studies were finally included.Four themes emerged:the involvement of patients and health professionals in the phases of design and development,patients’preferences,the characteristics of patients,and the motivators to use mHealth apps.The results indicated promising prospects for using mHealth apps to care for patients with breast cancer and identified the need for systematic efforts to develop and validate relevant apps.Conclusions:The attributes of patient characteristics,needs,and patient-reported outcomes data are vital components for developing mHealth apps for patients with breast cancer.Additionally,collaborative efforts,including patients,nurses,and other significant health professionals,should develop mHealth apps for breast cancer care.Additional research focusing on the design and development of mHealth apps for patients with breast cancer is warranted.
文摘Frailty is a state of late life decline and vulnerability, typified by physical weakness and decreased physiologic reserve. The epidemiology and pathophysiology of frailty share features with those of cardiovascular disease. Gait speed can be used as a measure of frailty and is a powerful predictor of mortality. Advancing age is a potent risk factor for cardiovascular disease and has been associated with an increased risk of adverse outcomes. Older adults comprise approximately half of cardiac surgery patients, and account for nearly 80% of the major complications and deaths following surgery. The ability of traditional risk models to predict mortality and major morbidity in older patients being considered for cardiac surgery may improve if frailty, as measured by gait speed, is included in their assessment. It is possible that in the future frailty assessment may assist in choosing among therapies (e.g., surgical vs. percutaneous aortic valve replacement for patients with aortic stenosis).
文摘The study was aimed to identify the problems and also to suggest some solutions for robotic systems applications in harvesting of kiwi and apples. The results obtained show that physicomechanical properties of the harvested fruits had an effect on the use of robotic systems. Parameters such as weight, height, width, thickness and surface area were identified as the main effect in robotic fruit harvesting. Image processing techniques also had direct effect on robotic systems operation which therefore requires careful selection procedure to achieve results accuracy. It was observed that the C# programming language used in robotic systems fruit harvesting should be parallel with the image processing to ensure accurate conversion of kinematic calculation, system input parameters and constant values. The use of hobby-type parts of a robot in the prototype study showed reliable results. However, to ensure functionality of the robotic systems application, industrial robots and servo engines should be used. It was also observed that the use of a gripper for picking the fruits from the branch must The engines that make the system work should be strong and the be made considering the physicomechanical properties of the fruit. cutting system should also be appropriate.
文摘Objective Neuroendocrine carcinomas(NECs) are resistant to currently available chemotherapy agents, and its therapeutic options are limited. Preclinical data have suggested synergy between capecitabine and temozolomide(CAPTEM). Therefore, we evaluated the efficacy and safety of CAPTEM in patients with metastatic NECs who have failed prior therapies.Methods A retrospective review was conducted on seven patients with metastatic NECs for whom platinum-based chemotherapies and hepatic chemoembolization failed. Patients received capecitabine(1000 mg twice daily on days 1-14) and temozolomide(150–200 mg/m^2 once daily on days 10–14) every 28 days. Tumor assessments were performed every two cycles.Results Among the seven patients treated, two achieved partial remission and four achieved stable disease. The total response rate was 29%, and the clinical benefit was 86%. Median progression-free survival was 10(range: 8–14) months. The most common toxicities were grade 1 and 2 neutropenia, grade 1 fatigue, and grade 1 and 2 hand-foot syndrome. No grade 4 toxicities or treatment-related deaths were observed.Conclusion Our study showed that the CAPTEM regimen is an effective and well-tolerated salvage option for NECs. Further prospective studies are warranted to evaluate optimal combinations of the CAPTEM regimen for NECs.

文摘Equipment selection for industrial process usually requires the extensive participation of industrial experts and technologists, which causes a serious waste of resources. This work presents an equipment selection knowledge base system for industrial styrene process(S-ESKBS) based on the ontology technology. This structure includes a low-level knowledge base and a top-level interactive application. As the core part of the S-ESKBS, the low-level knowledge base consists of the equipment selection ontology library, equipment selection rule set and Pellet inference engine. The top-level interactive application is implemented using S-ESKBS, including the parsing storage layer, inference query layer and client application layer. Case studies for the industrial styrene process equipment selection of an analytical column and an alkylation reactor are demonstrated to show the characteristics and implementability of the S-ESKBS.
文摘The paper starts with a presentation of the versatile leadership model developed by Kaplan and Kaiser and of their 360 feedback tool Leadership Versatility Index (LVI). Versatility can be generally defined as a mastery of opposites, as the ability to play multiple roles, even contradictory ones, without emphasizing some at the expense of others. The LVI has been designed to help managers understand their repertoire and how they can become more versatile leaders. It employs an innovative rating scale on which ideal score "0" is in the middle of it (the right amount), flanked by underdoing to the left (too little) and overdoing to the right (too much). The idea is to avoid the "more is better" design trap by providing a way for raters to indicate when managers go to counterproductive extremes. The LVI works with two-sided view of leadership based on two major pairs of opposites: directive vs. supportive leadership and execution vs. strategy. Interventions based on the LVI results help to overcome traditional behaviorism as they combine the outer work (behavioral change) with the inner work (personal change) of development. Application of the LV1 on a sample of the managers from Skoda Auto a.s. and verification of its practical value represented the core of the SAVS IGA project MM/O7/02. The last part of the paper is devoted to a presentation of the findings from this project. The LVI has been found to be both original and a very useful 360 feedback tool which can be addressed to two general groups of clients: (1) experienced senior managers; and (2) young perspective managers in the beginning of their career.
文摘The Chinese beauty and personal care market has been mainly dominated by big foreign brands such as L'Oreal and Maybelline, due to their good product reputation, high quality and other advantages. On the back of "Korean Wave" in China, the Korean cosmetics are expanding their presence in the Chinese market. Local companies must upgrade their brand image and enhance the competitiveness of their brands in the high-end market. In the future, with the increase of people's purchasing power, and the demand for high-end cosmetics, the competition in the Chinese cosmetic market will become fiercer.
文摘One of the aims of the Universal Declaration on B ioethics and Human Rights (UNESCO) is to "promote respect for human dignity and protect human rights",l Here are two overarching principles at work, ensuring that the biomedical sciences fulfill their task within an ethical framework. The principle of respect for human dignity is a universal moral concept, meant to be applied in human encounters. Protecting human rights underscores the legal principle of not only affirming the fundamental equality of all human beings, but equally safeguarding it. These two principles are universally defined, but are ordinarily specified by the particular value system of individual cultures in which they are employed. It is within such particular cultural application that their relevance stands out. The thrust of this paper is that, since principles are general action guides, they actually constitute a universal language for the analysis and evaluation of all human conduct. However, there is also recognition of the fact that moral contexts vary from culture to culture, and that while the scope of the two principles above is not restricted by any particular culture, it is indeed those cultural specifics of each moral context that constitute the framework within which the principles become operational. As general action guides, I will argue that these principles lack moral relevance outside of those particular cultural settings wherein they are contextualized. Without such relevance, these principles become meaningless mantras. I will further show that such principles do not merely uphold values informed by particular cultures, but they are an embodiment of values inherent to human nature in general. Consequently, these principles do not just serve as instruments for addressing issues peculiar to "Western bioethics" or any other particular cultural setting in an exclusive sense, but are also used for moderating bioethics discourse that transcend particular cultural boundaries. I will further explain that such universal discourse is potentially instructive with regards to how cultural universals are viewed in relation to the cultural particulars, and that this discourse essentially becomes a lingua franca for cross-cultural dialogue in bioethics.
