| 1 | A Subspace Version of the Powell–Yuan Trust-Region Algorithm for Equality Constrained Optimization显示文摘This paper studied subspace properties of the Celis–Dennis–Tapia(CDT)subproblem that arises in some trust-region algorithms for equality constrained optimization.The analysis is an extension of that presented by Wang and Yuan(Numer.Math.104:241–269,2006)for the standard trust-region subproblem.Under suitable conditions,it is shown that the trial step obtained from the CDT subproblem is in the subspace spanned by all the gradient vectors of the objective function and of the constraints computed until the current iteration.Based on this observation,a subspace version of the Powell–Yuan trust-region algorithm is proposed for equality constrained optimization problems where the number of constraints is much lower than the number of variables. The convergence analysis is given and numerical results arealso reported. | Geovani Nunes Grapiglia Jinyun Yuan Ya-xiang Yuan | 2013 | Journal of the Operations Research Society of China2013，1，4： | 3 |

| 7 | 甘美兰中基于两种模式的即兴性演奏规则的量化研究——以西爪哇Sunda族甘美兰Salendro为例显示文摘文化相对主义的视角使我们更加多元地去对待与认知他者(other)文化,甘美兰也因其独特的旋律性打击乐锣群文化受到了越来越多的关注,但目前对甘美兰的学习都只是停留在'看'的阶段,加之对甘美兰演奏中基于'地方性知识'进行即兴式演奏规则认知的缺失,使得甘美兰的即兴演奏看起来无迹可寻。通过笔者与Randy Geovani Putra两年的学习与实践合作发现,Embat模式与Patet模式的选择是影响甘美兰'即兴'演奏的基础,同时'听'和'感觉'成为成员间默契协作的条件和诉求。进而笔者结合Randy作为局内人长时间的教学与实践并以此为基础,通过对实际演奏乐谱的量化分析,对西爪哇巽它族甘美兰Salendro演奏中两种模式的使用规则进行初步的探析。 | 岳子威 Randy Geovani Putra | 2020 | 歌海2020，，1： | 1 |

| 13 | 西爪哇Sunda甘美兰中Salendro的演奏规律初探显示文摘甘美兰是东南亚锣群文化的代表,吸引了各国民族音乐学家前往研究,拥有深厚的文化底蕴。如今中国已有多所高校引进甘美兰进入博物馆实际演奏,但没有专业老师的带领下,学生很难掌握乐器演奏的规律,笔者在有限的条件下,通过理论学习、实际演奏和外教沟通中去认识甘美兰乐队,探寻西爪哇Sunda甘美兰中Salendro的演奏规律内在规律,发现乐谱中Lagu、Laras、Irama、Patet四个名词对于核心旋律的探寻有重要意义。 | 万婷 Randy Geovani Putra | 2021 | 黄河之声2021，，11： | 0 |
| 14 | Epidemiological and clinical characteristics of COVID-19 in a Brazilian public hospital显示文摘BACKGROUND The coronavirus disease 2019(COVID-19)pandemic has become a major health concern worldwide.In that context,the understanding of epidemiological and clinical features associated with the disease and its severity is crucial for the establishment of strategies aimed at disease control and remedy.AIM To describe epidemiological features,signs,symptoms,and laboratory findings among severely ill COVID-19 patients from an inten-sive care unit in northeastern Brazil as well as to evaluate predictor factors for disease outcomes.METHODS This is a prospective single-center study that evaluated 115 patients admitted to the intensive care unit in a northeastern Brazilian hospital.RESULTS The patients had a median age of 65.60±15.78 years.Dyspnea was the most frequent symptom,affecting 73.9%of the patients,followed by cough(54.7%).Fever was reported in approximately one-third of patients and myalgia in 20.8%of the patients.At least two comorbidities were found in 41.7%of the patients,and hypertension was the most prevalent(57.3%).In addition,having two or more comorbidities was a predictor of mortality,and lower platelet count was positively associated with death.Nausea and vomiting were two symptoms that were predictors of death,and the presence of a cough was a protective factor.CONCLUSION This is the first report of a negative correlation between cough and death in severely ill severe acute respiratory syndrome coronavirus 2-infected individuals.The associations between comorbidities,advanced age,and low platelet count and the outcomes of the infection were similar to the results of previous studies,highlighting the relevance of these features. | Fillipe Dantas Pinheiro Luana Weber Lopes Rafael Santos Dantas Miranda Dórea Glauber Rocha Lima Araújo Filipe Antônio França da Silva Breno Bittencourt de Brito Maria Luísa Cordeiro Santos Geovani Moreno Santos Júnior Maria Teresa Araújo de Lorenzo Barcia Renata de Amorim Marques AndréBezerra Botelho Anna Carolina Saúde Dantas Davi Tanajura Costa Adriano Fernandes Teixeira Cláudio Lima Souza Lucas Miranda Marques Guilherme Barretos Campos Márcio Vasconcelos Oliveira Dulciene Maria de Magalhães Queiroz Fabrício Freire de Melo | 2023 | World Journal of Clinical Cases2023，11，8： | 0 |
