Flabellariopteris,a new aquatic fern leaf from the Late Triassic of western Liaoning,China

An aquatic fern leaf, Flabellariopteris mii Sun gen. et sp. nov. from the Late Triassic of Western Liaoning, China, is described and proposed as the type species of the new morphortaxon of the Marsileaceae. The fossil leaves are preserved as impression. No fertile and rhizomatic materials are found. The leaves attached at a common point on the top of the petiole are composed of two leaflets joined basally in an opposite arrangement. The petiole is slender. The leaflet is fan-shaped or semi-circular, and commonly divided into four wedge-shaped lobes. Terminal margin of lobes is usually incised, incisions shallow or deep, with bluntly rounded or notched apex. The veins are conspicu- ously dichotomous, but anastomoses and marginal vein are absent. The unique morphological features, including two- parted thin leaflets, size, shape, veins and slender petiole, indicate that the present specimen represents an aquatic fern, which is the oldest fossil record and the first megafossil evidence assignable to Marsileaceae from the Triassic floras.

Distribution of late gadolinium enhancement in end-stage hypertrophic cardiomyopathy and dilated cardiomyopathy: Differential diagnosis and prediction of cardiac outcome

Background

The prognostic implications of late gadolinium enhancement (LGE) have been evaluated in ischemic and non-ischemic cardiomyopathies. The present study analyzed LGE distribution in patients with end-stage hypertrophic cardiomyopathy (ES-HCM) and with dilated cardiomyopathy (DCM), and tried to identify high risk patients in DCM.

Methods

Eleven patients with ES-HCM and 72 with DCM underwent cine- and LGE-cardiac magnetic resonance and ultrasound cardiography. The patient outcome was analyzed retrospectively for 5 years of follow-up.

Results

LGE distributed mainly in the inter-ventricular septum, but spread more diffusely into other left ventricular segments in patients with ES-HCM and in a certain part of patients with DCM. Thus, patients with DCM can be divided into three groups according to LGE distribution; no LGE (n = 24), localized LGE (localized at septum, n = 36), and extensive LGE (spread into other segments, n = 12). Reverse remodeling occurred after treatment in patients with no LGE and with localized LGE, but did not in patients with extensive LGE and with ES-HCM. The event-free survival rate for composite outcome (cardiac death, hospitalization for decompensated heart failure or ventricular arrhythmias) was lowest in patients with extensive LGE (92%, 74% and 42% in no LGE, localized LGE, and extensive LGE, p = 0.02 vs. no LGE), and was comparable to that in patients with ES-HCM (42%).

Conclusions

In DCM, patients with extensive LGE showed no functional recovery and the lowest event-free survival rate that were comparable to patients with ES-HCM. The analysis of LGE distribution may be valuable to predict reverse remodeling and to identify high-risk patients.     

A mixed integer linear programming approach to minimize the number of late jobs with and without machine availability constraints

This study investigates scheduling problems that occur when the weighted number of late jobs that are subject to deterministic machine availability constraints have to be minimized. These problems can be modeled as a more general job selection problem. Cases with resumable, non-resumable, and semi-resumable jobs as well as cases without availability constraints are investigated. The proposed efficient mixed integer linear programming approach includes possible improvements to the model, notably specialized lifted knapsack cover cuts. The method proves to be competitive compared with existing dedicated methods: numerical experiments on randomly generated instances show that all 350-job instances of the test bed are closed for the well-known problem 1|_ri|∑_wiUi$1|r_i|\sum w_i{U}_i$. For all investigated problem types, 98.4% of 500-job instances can be solved to optimality within 1 hour.     

倒春寒后不同措施对不同类型冬小麦冻害减灾效果研究

2007年冬小麦遭受晚霜冻害,选择遭受严重霜冻的大穗型冬小麦淄麦12号进行刈割对比试验,同时在冬小麦遭受倒春寒冻害地块以临麦2号为材料进行追施肥、水、化控剂对比试验。结果表明：冬小麦刈割后基部腋芽再次萌发虽可形成一定产量,但与对照相比,单株性状变差,产量明显降低。因此,霜冻后不应刈割,应积极采取科学的补救措施,把灾害造成的损失降到最低。而受冻后及时追施速效氮肥并浇水和喷施植物生长调节剂天达2116减灾效果较好,比未采取任何减灾措施穗数增加63×104hm2,穗粒数增加3.4粒,千料重增加2.5g,增产1536.0 kg/hm2,增产幅度达38.7%。     

晚清官书局研究综述

官书局是晚清重要的官方出版机构,在出版史、文化史上占有重要的位置。自清末至今,学者们对官书局的研究各有侧重,显示了研究旨趣的不同以及成果的丰富。但研究中仍有不足之处,有待于学者们开展进一步的研究。     

宋末元初江西词派的第一人--刘秉忠及其词

本文对刘秉忠及其词进行探索,认为刘秉忠想出人头地,但未必是想以为蒙古统治者服务达到出人头地的目的,他为蒙古统治者服务有出于不得已的一面。刘秉忠为蒙古统治者服务与那些投降蒙古统治者的南宋官员不同,他祖籍为汉族人,他出生地为蒙古统治者占领地。刘秉忠随忽必烈征战云南、鄂州等地,保护了南宋许多臣民。刘秉忠向蒙古统治者建言,保存了汉族儒家的许多文化传统。刘秉忠的词内容丰富,他被《元名儒草堂诗余》编辑者作为此书的第一人,这似乎反映此书编辑者以蒙古高官和颂扬蒙古王朝的词掩盖追悼宋王朝的主旨。     

晚唐咏史诗对社会兴亡人生成败的归因简析

咏史诗,是在混乱的政治、战乱的社会和颓靡的时代里,晚唐诗人解剖历史和人生的结晶。其对王朝兴亡、人生成败的归因是辩证、全面而深刻的。诗人形象演绎了“成由勤俭破由奢”的历史逻辑;对女人非祸水作了鲜明有力、符合逻辑的辩正;在强调德、能等人事因素影响兴亡成败的同时,肯定了“时”“运”“命”等非人事的偶然因素对兴亡成败的影响力。
