Interwell connectivities are fundamental parameters required to manage waterfloods in oil reservoirs. Data-driven models, such as the capacitance-resistance model （CRM）, are fast tools to estimate these parameters from time-correlations of input （injection rates） and output （production rates） signals. Noise and structure of the input time-series impose limits on the information that can be extracted from a given data-set. This work uses the CRM to study general prescriptions for the design of input signals that enhance the information content of injection/production data in the estimation of well-to-well interactions. Numerical schemes and general features of the optimal input signal strategy are derived for this problem.

KEY POINTSAbstract: The 2004 recommendations on water and sodium intake from the Institute of Medicine (IOM) of the National Academy of Sciences are targeted primarily at sedentary Americans. These guidelines for water and salt intake should not be applied to athletes.  Athletes who follow the IOM recommendations to the letter may actually put themselves at risk for unintended decreases in performance or even untoward health consequences.

Excessive application of fertilizers and pesticides as well as discharge of undecontaminated and unrecycled waste of livestock and poultry into farmland has caused serious non-point source pollution (NSP) of farmland in China. with the traditional mode of irrigation and drainage in rice-based irrigation systems, the pollution of farmland drainage water has become more and more serious. Traditional irrigation and drainage systems only focus on issues concerning water quantity, i.e. the capacity of irrigation in drought and drainage in waterlogging period, yet have no requirement on water quality improvement. how to clean the water quality of farmland drainage through remodeling the existing irrigation and drainage systems has a very important realistic meaning. Pond is an important irrigation facility in rice-based irrigation systems in southern China, which has the functions of not only a storage of water from canals but also collections of surface runoffs and farmland drainage for recycling use. Such water storage features of pond provide the possibility and potential capacity for drainage water treatment by managing such features as treatment basins as the growth of aquatic plants as well as living of fishes, batrachia and microorganisms in pond forms a soil-plant-microorganism ecological system. To explore the potential capacity of pond for drainage water nutrient reduction, the Zhanghe Irrigation System of Hubei, a typical "melon-on-the-vine" system in southern China is selected as the research site. The results of pond survey and field experiments demonstrate that plenty of ponds are suitable for collecting and cleaning paddy field drainage, and the ponds are favorable in reducing N, P nutrients in the drainage water. Other issues, e.g. how to maximize such capacity and what strategies should be sought to make existing treatment basins hydraulically more efficient, are also discussed.

Somatostatin analogs were initially developed for the control of hormonal syndromes associated with neuro-endocrine tumors (NETs). In recent years, accumul ating data has supported their role as antiproliferative agents, capable of stabilizing tumor growth in patients with metastatic neuroendocrine malignancies, including carci-noid and pancreatic endocrine tumors. A phase Ⅲ, ran-domized, placebo-controlled trial has now demonstrated that octreotide long-acting repeatable (LAR) 30 mg can significantly prolong time to tumor progression among patients with metastatic midgut NETs regardless of functional status, chromogranin A level or age. In addition to signif icantly lengthening time to tumor pro-gression in the overall study population, subset analysis suggests that patients with low tumor burden are most likely to experience disease stabilization with octreotide LAR 30 mg, supporting the early use of octreotide LAR in patients with metastatic disease. Further research efforts are underway to evaluate the use of somatostatin analogs as antiproliferative agents in other types of gastroenteropancreatic-NETs. Ongoing studies are also evaluating novel somatostatin analogs and somatostatin analogs in combination with other anti-tumor therapies.

we consider context-free grammars of the form G = {f → f^b1＋b2＋1g^a1＋a2, g → f^b1 g^a1＋1},where ai and bi are integers sub ject to certain positivity conditions. Such a grammar G gives rise to triangular arrays {T（n, k）}0≤k≤n satisfying a three-term recurrence relation. Many combinatorial sequences can be generated in this way. Let Tn （x） =∑k=0^n T（n, k）x^k. Based on the differential operator with respect to G, we define a sequence of linear operators Pn such that Tn＋1（x） = Pn（Tn（x））. Applying the characterization of real stability preserving linear operators on the multivariate polynomials due to Borcea and Br？ndén, we obtain a necessary and sufficient condition for the operator Pn to be real stability preserving for any n. As a consequence, we are led to a sufficient condition for the real-rootedness of the polynomials defined by certain triangular arrays, obtained by wang and ***, as special cases we obtain grammars that lead to identities involving the whitney numbers and the Bessel numbers.

Dear Editor, The patient is a 45-year-old male who presented to an outside clinic in 2014 for evaluation of painful ejaculation, infertility, and difficulty with urination for as long as he could remember. He reported no past significant medical or surgical history and no family history of infertility. He was given a trial of tamsulosin without improvement in his symptoms. Initial semen analysis demonstrated azoospermia.

目的 :在早期类风湿关节炎(rheumatoid arthritis,RA)的诊断中,1987年美国风湿病学会(AmericanCollege of Rheumatology,ACR;旧称AmericanRheumatism Association,ARA)的诊断标准因为缺乏敏感度而受到质疑。本研究的目的是建立新的RA分类标准。方法 :由ACR和欧洲抗风湿病联盟(EuropeanLeague Against Rheumatism,EULAR)共同组成的工作小组,分三个阶段建立RA新的分类标准。研究的目标人群是初发的未分化关节炎患者,主要研究目的是寻找能够预测这些病人发展为RA的危险因素,并将RA疾病特点定义为持续性和/或侵蚀性关节炎。结果 :在新的分类标准中,确诊RA至少需要一个关节有明确的滑膜炎表现,除外其他可能导致滑膜炎症的疾病,同时以下四项评分的总分≥6分(最高10分):受累关节的数量和部位(0-5分)、血清学自身抗体异常(0-3分)、急性期反应物升高(0-1分)和症状持续时间(共分两级;0-1分)。结论 :既往诊断RA比较依赖骨破坏这一RA晚期表现,而新的分类标准着重于疾病早期表现而不是晚期特点,将疾病特点重新定义为持续性和/或侵蚀性滑膜炎。这一新标准的推出将再次强调了RA早期诊断的必要性以及早期有效治疗对于预防或减少不良后遗症的发生具有重要意义。
