| 1 | 单窗算法的大气参数估计方法显示文摘根据地表热辐射传导方程,提出了一个简单可行且精度较高的专门用于从TM6数据中演算地表温度的方法———单窗算法。这一算法把大气和地表状态对地表热传导的影响直接包括在演算公式中。该方法需要两个大气参数进行地表温度的演算,即大气平均作用温度和大气透射率。本文论述这两个大气参数的估计方法:根据大气水分含量或地表附近空气湿度来估计大气透射率;通过分析标准大气剖面资料,尤其是大气水分和气温随高程的变化规律,根据地表温度推算大气平均作用温度。 | 覃志豪 LI Wenjuan ZHANG Minghua Arnon Karnieli Pedro Berliner | 2003 | 国土资源遥感2003,15,2: | 352 |
| 2 | 用陆地卫星TM6数据演算地表温度的单窗算法显示文摘陆地卫星 TM数据 (TM6)热波段表示地表热辐射和地表温度变化。长期以来 ,从 TM6数据中演算地表温度通常是通过所谓大气校正法。这一方法需要估计大气热辐射和大气对地表热辐射传导的影响 ,计算过程很复杂 ,误差也较大 ,在实际中应用不多。根据地表热辐射传导方程 ,推导出一个简单易行并且精度较高的演算方法 ,把大气和地表的影响直接包括在演算公式中。该算法需要用地表辐射率、大气透射率和大气平均温度 3个参数进行地表温度的演算。验证表明 ,该方法的地表温度演算较高。当参数估计没有误差时 ,该方法的地表温度演算精度达到 <0 .4℃ ,在参数估计有适度误差时 ,演算精度仍达 <1 .1℃。因该方法适用于仅有一个热波段的遥感数据 ,故称为单窗算法。 | 覃志豪 Zhang Minghua Arnon Karnieli Pedro Berliner | 2001 | 地理学报2001,56,4: | 816 |
| 3 | Pathogenesis and clinical management of Helicobacter pylori gastric infection显示文摘Helicobacter pylori(H.pylori)is a gram-negative bacterium that infects approximately 4.4 billion individuals worldwide.However,its prevalence varies among different geographic areas,and is influenced by several factors.The infection can be acquired by means of oral-oral or fecal-oral transmission,and the pathogen possesses various mechanisms that improve its capacity of mobility,adherence and manipulation of the gastric microenvironment,making possible the colonization of an organ with a highly acidic lumen.In addition,H.pylori presents a large variety of virulence factors that improve its pathogenicity,of which we highlight cytotoxin associated antigen A,vacuolating cytotoxin,duodenal ulcer promoting gene A protein,outer inflammatory protein and gamma-glutamyl transpeptidase.The host immune system,mainly by means of a Th1-polarized response,also plays a crucial role in the infection course.Although most H.pylori-positive individuals remain asymptomatic,the infection predisposes the development of various clinical conditions as peptic ulcers,gastric adenocarcinomas and mucosa-associated lymphoid tissue lymphomas.Invasive and non-invasive diagnostic methods,each of them with their related advantages and limitations,have been applied in H.pylori detection.Moreover,bacterial resistance to antimicrobial therapy is a major challenge in the treatment of this infection,and new therapy alternatives are being tested to improve H.pylori eradication.Last but not least,the development of effective vaccines against H.pylori infection have been the aim of several research studies. | Breno Bittencourt de Brito Filipe Ant?nio Fran?a da Silva Aline Silva Soares Vinícius Afonso Pereira Maria Luísa Cordeiro Santos Mariana Miranda Sampaio Pedro Henrique Moreira Neves Fabrício Freire de Melo | 2019 | World Journal of Gastroenterology2019,25,37: | 84 |
| 4 | 三相并网逆变器比例谐振控制及其网压前馈问题分析显示文摘静止坐标系下的比例谐振控制因其具有对特定频率响应速度快、不存在耦合项并易实现谐波补偿这三个显著特点得到了广泛的关注,并被应用于多种分布式发电系统当中。本文对静止坐标系下的比例谐振控制进行了说明与分析,同时针对比例谐振控制的特点,提出了一种带有比例系数的正序网压前馈控制方法。该方法通过引入正序网压前馈环节,相比传统的比例谐振控制方法进一步提高了系统的动态响应能力,在逆变器公用接入点(PCC)电压畸变的情况下,正序网压前馈环节降低了网压畸变对并网电流造成的负面影响,并得到了实验的验证。 | 马琳 金新民 唐芬 Pedro Rodriguez 孙凯 | 2012 | 电工技术学报2012,27,8: | 63 |

| 7 | Complications of hip fractures: A review显示文摘Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections(alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum-a major contributor to fracture healing- in the femoral neck. In extracapsularfractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients. | Pedro Carpintero Jose Ramón Caeiro Rocío Carpintero Angela Morales Samuel Silva Manuel Mesa | 2014 | World Journal of Orthopedics2014,5,4: | 31 |
| 8 | Thermal Treatment of Hydrocarbon-Impacted Soils" A Review of Technology Innovation for Sustainable Remediation显示文摘在受烃污染的土壤和底泥的修复处理工艺中,热处理工艺因其能快速且稳定地达到修复标准而占有重要地位。然而,持续高温属于能源密集型操作,且可破坏土壤性质,因此尽管此工艺被广泛应用,关于这些工艺的环境兼容性和可持续性却极少被报道。鉴于此,我们对几个针对烃污染土壤的常用热处理工艺进行了概述,对它们的潜在环境影响进行了评估;并基于能源需求、水需求、系统生态和土壤科学的全面考虑,提出了可持续且影响较小的发展框架。至今还没有一种通用适合的热处理工艺。工艺的恰当选择要根据污染状况(包括环境中存在的烃种类)和场地特征(如被污染土壤的性质、水含量和热敏性)而定。总之,处理工程与土壤科学、生态系统和植物生物学研究的有机结合是攻克技术瓶颈、提高去除率和促进热处理工艺可持续性发展的关键所在。 | Julia E.

| 9 | Triglyceride levels and apolipoprotein E polymorphism in patients with acute pancreatitis显示文摘BACKGROUND:Hypertriglyceridemia is an unusual cause of acute pancreatitis and sometimes considered to be an epiphenomenon.This study aimed to investigate the clinical and analytical features and the APOE genotypes in patients with acute pancreatitis and severe hypertriglyceridemia.METHODS:We undertook a one-year,prospective study of patients with acute pancreatitis whose first laboratory analysis on admission to the emergency department included measurement of serum triglycerides.The APOE genotype was determined and the patients answered an established questionnaire within the first 24 hours concerning their alcohol consumption,the presence of co-morbidities and any medications being taken.The patients' progression,etiological diagnosis,hospital stay and clinical and radiological severity were all recorded.RESULTS:Hypertriglyceridemia was responsible for 7 of 133 cases of pancreatitis (5%);the remaining cases were of biliary (53%),idiopathic (26%),alcoholic (11%) or other (5%) origin.Compared with these remaining cases,the patients with hypertriglyceridemia were significantly younger,had more relapses,and more often had diabetes mellitus.They usually consumed alcohol or consumed it excessively on the days before admission.Also,the ε4 allele of the APOE gene was more common in this group (P<0.05).CONCLUSION:One of 20 episodes of acute pancreatitis is caused by hypertriglyceridemia and it is linked to genetic (ε4 allele) and comorbid factors such as diabetes and,especially,alcohol consumption. | Radka Ivanova Susana Puerta Alfonso Garrido Ignacio Cueto Ana Ferro María José Ariza Andrés Cobos Pedro González-Santos Pedro Valdivielso | 2012 | Hepatobiliary & Pancreatic Diseases International2012,11,1: | 26 |
| 10 | Endoscopic papillary large balloon dilation after limited sphincterotomy for difficult biliary stones显示文摘AIM:To assess the efficacy and safety of endoscopic papillary large balloon dilation after biliary sphincterotomy for difficult bile duct stones retrieval.METHODS:Retrospective review of consecutive patients submitted to the technique during 18 mo.The main outcomes considered were:efficacy of the procedure(complete stone clearance;number of sessions;need of lithotripsy) and complications.RESULTS:A total of 30 patients with a mean age of 68 ± 10 years,23 female(77%) and 7 male(23%) were enrolled.In 10 patients,a single stone was found in the common bile duct(33%) and in 20 patients multiple stones(67%) were found.The median diameter of the stones was 17 mm(12-30 mm).Dilations were performed with progressive diameter Through-TheScope balloons(up to 12,15) or 18 mm.Complete retrieval of stones was achieved in a single session in 25 patients(84%) and in two sessions in 4 patients(13%).Failure occurred in 1 case(6%).Mechanical lithotripsywas performed in 6 cases(20%).No severe complications occurred.One patient(3%) had mild-grade post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis.CONCLUSION:Endoscopic balloon dilatation with a large balloon after endoscopic sphincterotomy is a safe and effective technique that could be considered an alternative choice in therapeutic ERCP. | Ana Rebelo Pedro Moutinho Ribeiro António Pinto Correia José Cotter | 2012 | World Journal of Gastrointestinal Endoscopy2012,4,5: | 22 |
| 11 | 在为困难的 choledocholithiasis 的 sphincterotomy 以后的内视镜的乳突的汽球膨胀: 控制盒子的研究显示文摘 AIM:To evaluate the efficacy and safety of endoscopic sphincterotomy(EST) + endoscopic papillary large balloon dilation(EPLBD)vs isolated EST.METHODS:We conducted a retrospective single center study over two years,from February 2010 to January 2012.Patients with large(≥ 10 mm),single or multiple bile duct stones(BDS),submitted to endoscopic retrograde cholangio-pancreatography(ERCP) were included.Patients in Group A underwent papillary large balloon dilation after limited sphincterotomy(EST+EPLBD),using a through-the-scope balloon catheter gradually inflated to 12-18 mm according to the size of the largest stone and the maximal diameter of the distal bile duct on the cholangiogram.Patients in Group B(control group) underwent isolated sphincterotomy.Stones were removed using a retrieval balloon catheter and/or a dormia basket.When necessary,mechanical lithotripsy was performed.Complete clearance of the bile duct was documented with a balloon catheter cholangiogram at the end of the procedure.In case of residual lithiasis,a double pigtail plastic stent was placed and a second ERCP was planned within 4-6 wk.Some patients were sent for extracorporeal lithotripsy prior to subsequent ERCP.Outcomes of EST+EPLBD(Group A) vs isolated EST(Group B) were compared regarding efficacy(complete stone clearance,number of therapeutic sessions,mechanical and/or extracorporeal lithotripsy,biliary stent placement) and safety(frequency,type and grade of complications).Statistical analysis was performed using χ 2 or Fisher’s exact tests for the analysis of categorical parameters and Student’s t test for continuous variables.A P-value of less than 0.05 was considered statistically significant.RESULTS:One hundred and eleven patients were included,68(61.3%) in Group A and 43(38.7%) in Group B.The mean diameter of the stones was similar in the two groups(16.8 ± 4.4 and 16.0 ± 6.7 in Groups A and B,respectively).Forty-eight(70.6%) patients in Group A and 21(48.8%) in Group B had multiple BDS(P = 0.005).Overall,balloon dilation was performed up to 12 mm in 10(14.7%) patients,13.5 mm in 17(25.0%),15 mm in 33(48.6%),16.5 mm in 2(2.9%) and 18 mm in 6(8.8%) patients,taking into account the diameter of the largest stone and that of the bile duct.Complete stone clearance was achieved in sixty-five(95.6%) patients in Group A vs 30(69.8%) patients in Group B,and was attained within the first therapeutic session in 82.4% of patients in Group A vs 44.2% in Group B(P < 0.001).Patients submitted to EST+EPLBD underwent fewer therapeutic sessions(1.1 ± 0.3 vs 1.8 ± 1.1,P < 0.001),and fewer required mechanical(14.7% vs 37.2%,P = 0.007) or extracorporeal(0 vs 18.6%,P < 0.001) lithotripsy,as well as biliary stenting(17.6% vs 60.5%,P < 0.001).The rate of complications was not significantly different between the two groups.CONCLUSION:EST+EPLBD is a safe and effective technique for treatment of difficult BDS,leading to high rates of complete stone clearance and reducing the need for lithotripsy and biliary stenting. | Bruno Rosa Pedro Moutinho Ribeiro Ana Rebelo António Pinto Correia José Cotter | 2013 | World Journal of Gastrointestinal Endoscopy2013,5,5: | 21 |
| 12 | Forecasting and trading cryptocurrencies with machine learning under changing market conditions显示文摘This study examines the predictability of three major cryptocurrencies—bitcoin,ethereum,and litecoin—and the profitability of trading strategies devised upon machine learning techniques(e.g.,linear models,random forests,and support vector machines).The models are validated in a period characterized by unprecedented turmoil and tested in a period of bear markets,allowing the assessment of whether the predictions are good even when the market direction changes between the validation and test periods.The classification and regression methods use attributes from trading and network activity for the period from August 15,2015 to March 03,2019,with the test sample beginning on April 13,2018.For the test period,five out of 18 individual models have success rates of less than 50%.The trading strategies are built on model assembling.The ensemble assuming that five models produce identical signals(Ensemble 5)achieves the best performance for ethereum and litecoin,with annualized Sharpe ratios of 80.17%and 91.35%and annualized returns(after proportional round-trip trading costs of 0.5%)of 9.62%and 5.73%,respectively.These positive results support the claim that machine learning provides robust techniques for exploring the predictability of cryptocurrencies and for devising profitable trading strategies in these markets,even under adverse market conditions. | Helder Sebastiao Pedro Godinho | 2021 | Financial Innovation2021,7,1: | 21 |

| 14 | Recruitment maneuvers in acute respiratory distress syndrome: The safe way is the best way显示文摘Acute respiratory distress syndrome(ARDS) represents a serious problem in critically ill patients and is associated with in-hospital mortality rates of 33%-52%. Recruitment maneuvers(RMs) are a simple, low-cost, feasible intervention that can be performed at the bedside in patients with ARDS. RMs are characterized by the application of airway pressure to increase transpulmonary pressure transiently. Once non-aerated lung units are reopened, improvements are observed in respiratory system mechanics, alveolar reaeration on computed tomography, and improvements in gas exchange(functional recruitment). However, the reopening process could lead to vascular compression, which can be associated with overinflation, and gas exchange may not improve as expected(anatomical recruitment). The purpose of this review was to discuss the effects of different RM strategies- sustained inflation, intermittent sighs, and stepwise increases of positive end-expiratory pressure(PEEP) and/or airway inspiratory pressure- on the following parameters: hemodynamics, oxygenation, barotrauma episodes, and lung recruitability through physiological variables and imaging techniques. RMs and PEEP titration are interdependent events for the success of ventilatory management. PEEP should be adjusted on the basis of respiratory system mechanics and oxygenation. Recent systematic reviews and meta-analyses suggest that RMs are associated with lower mortality in patients with ARDS. However, the optimal RM method(i.e., that providing the best balance of benefit and harm) and the effects of RMs on clinical outcome are still under discussion, and further evidence is needed. | Raquel S Santos Pedro L Silva Paolo Pelosi Patricia RM Rocco | 2015 | World Journal of Critical Care Medicine2015,4,4: | 19 |
| 15 | Cardioprotection and pharmacological therapies in acute myocardial infarction: Challenges in the current era显示文摘In patients with an acute ST-segment elevation myocardial infarction, timely myocardial reperfusion using primary percutaneous coronary intervention is the most effective therapy for limiting myocardial infarct size, preserving left-ventricular systolic function and reducing the onset of heart failure. Within minutes after the restoration of blood flow, however, reperfusion itself results in additional damage, also known as myocardial ischemia-reperfusion injury. An improved understanding of the pathophysiological mechanisms underlying reperfusion injury has resulted in the identification ofseveral promising pharmacological(cyclosporin-A, exenatide, glucose-insulin-potassium, atrial natriuretic peptide, adenosine, abciximab, erythropoietin, metoprolol and melatonin) therapeutic strategies for reducing the severity of myocardial reperfusion injury. Many of these agents have shown promise in initial proofof-principle clinical studies. In this article, we review the pathophysiology underlying myocardial reperfusion injury and highlight the potential pharmacological interventions which could be used in the future to prevent reperfusion injury and improve clinical outcomes in patients with coronary heart disease. | Alberto Dominguez-Rodriguez Pedro Abreu-Gonzalez Russel J Reiter | 2014 | World Journal of Cardiology2014,6,3: | 18 |

| 17 | The RNA Modification N^6-methyladenosine and Its Implications in Human Disease显示文摘Impaired gene regulation lies at the heart of many disorders,including developmental diseases and cancer.Furthermore,the molecular pathways that control gene expression are often the target of cellular parasites,such as viruses.Gene expression is controlled through multiple mechanisms that are coordinated to ensure the proper and timely expression of each gene.Many of these mechanisms target the life cycle of the RNA molecule,from transcription to translation.Recently,another layer of regulation at the RNA level involving RNA modifications has gained renewed interest of the scientific community.The discovery that N^6-methyladenosine(m^6A),a modification present in m RNAs and long noncoding RNAs,can be removed by the activity of RNA demethylases,launched the field of epitranscriptomics;the study of how RNA function is regulated through the addition or removal of post-transcriptional modifications,similar to strategies used to regulate gene expression at the DNA and protein level.The abundance of RNA post-transcriptional modifications is determined by the activity of writer complexes(methylase) and eraser(RNA demethylase) proteins.Subsequently,the effects of RNA modifications materialize as changes in RNA structure and/or modulation of interactions between the modified RNA and RNA binding proteins or regulatory RNAs.Disruption of these pathways impairs gene expression and cellular function.This review focuses on the links between the RNA modification m^6A and its implications in human diseases. | Pedro J.Batista | 2017 | Genomics, Proteomics & Bioinformatics2017,15,3: | 17 |

| 19 | Nucleation and Growth Mechanisms for Pd-Pt Bimetallic Nanodendrites and Their Electrocatalytic Properties显示文摘In a seed-mediated synthesis, nanocrystal growth is often described by assuming the absence of homogeneous nucleation in the solution. Here we provide new insights into the nucleation and growth mechanisms underlying the formation of bimetallic nanodendrites that are characterized by a dense array of Pt branches anchored to a Pd nanocrystal core. These nanostructures can be easily prepared by a one-step, seeded growth method that involves the reduction of K2PtCl4 by L-ascorbic acid in the presence of 9-nm truncated octahedral Pd seeds in an aqueous solution. Transmission electron microscopy (TEM) and high-resolution TEM analyses revealed that both homogeneous and heterogeneous nucleation of Pt occurred at the very early stages of the synthesis and the Pt branches grew through oriented attachment of small Pt particles that had been formed via homogeneous nucleation. These new findings contradict the generally accepted mechanism for seeded growth that only involves heterogeneous nucleation and simple growth via atomic addition. We have also investigated the electrocatalytic properties of the Pd-Pt nanodendrites for the oxygen reduction and formic acid oxidation reactions by conducting a comparative study with foam-like Pt nanostructures prepared in the absence of Pd seeds under otherwise identical conditions. | Byungkwon Lim Majiong Jiang Taekyung Yu Pedro H.C.Camargo Younan Xia | 2010 | Nano Research2010,3,2: | 17 |
| 20 | Managing diabetic macular edema: The leading cause of diabetes blindness显示文摘Diabetic macular edema (DME) is the leading cause of blindness in young adults in developed countries, affecting 12% of type 1 and 28% of type 2 diabetic patients. The gold standard DME treatment should be based on a good control of glycemia along with control of lipids and renal function. However, despite the systemic metabolic control values being essential for patients with diabetic retinopathy (DR), it has proven to be insufficient for DME if it appears. With these patients, additional measures are needed in order to avoid the subsequent loss of vision. While laser treatment of DME has been the only valid treatment so far, it has been inadequate in chronic cases. The introduction of new treatments, such as intravitreal corticosteroids or anti-VEGF drugs, have recently shown their safety and efficacy and together with laser photocoagulation are becoming the treatments of choice in the management of DME. | Pedro Romero-Aroca | 2011 | World Journal of Diabetes2011,2,6: | 15 |
