II.AFTER THE CONTEST BEGINS:

A. View the contest problems via the contest web site:

Teams can view the contest problems via the contest web site when the contest begins at

8PM EST on Thursday January 28, 2016:

1.The contest problems will become available precisely at 8PM EST on Thursday January

28, 2016; team members can view them by visiting

https://www.sodocs.net/doc/9217520091.html,/undergraduate/contests/mcm. No password will be needed to

view the problems; simply go to the contest web site at or after 8PM EST on Thursday,

January 28, 2016 and you will see a link to view the problems.

2.The contest problems will become available precisely at 7:50PM EST on Thursday

January 28, 2016 on the following mirror sites:

https://www.sodocs.net/doc/9217520091.html,/mcm/index.html

https://www.sodocs.net/doc/9217520091.html,/mcm/index.html

https://www.sodocs.net/doc/9217520091.html,/mcm/index.html

If you cannot access any of the sites, there may be a problem with your local Internet

connection. Contact your local Internet service provider to resolve the issue.

B. Choose a problem:

Each team may choose any one of the six problem choices and should submit a solution to

only one problem.

?MCM problems are Problem A, Problem B or Problem C.

?ICM problems are Problem D, Problem E or Problem F.

C. Teams prepare solutions:

1.Teams may use any inanimate source of data or materials: computers, software,

references, web sites, books, etc. ALL SOURCES USED MUST BE CREDITED. Failure

to credit a source will result in a team being disqualified from the competition.

2.Team members may not seek help from or discuss the problem with their advisor or

anyone else, except other members of the same team. Input in any form from anyone other

than student team members is strictly forbidden. This includes email, telephone contact,

and personal conversation, communication via web chat or other question-answer systems,

or any other form of communication.

3.Partial solutions are acceptable. There is no passing or failing cut-off score, and numerical

scores will not be assigned. The MCM/ICM contest judges are primarily interested in the

team’s approach and methods.

4.Summary Sheet: The summary is an essential part of your MCM/ICM paper. The judges

place considerable weight on the summary, and winning papers are often distinguished

from other papers based on the quality of the summary.

To write a good summary, imagine that a reader will choose whether to read the body of

the paper based on your summary: Your concise presentation in the summary should

inspire a reader to learn about the details of your work. Thus, a summary should clearly

describe your approach to the problem and, most prominently, your most important

conclusions. Summaries that are mere restatements of the contest problem, or are a cut-

and-paste boilerplate from the Introduction are generally considered to be weak.

Besides the summary sheet as described each paper should contain the following

sections:

?Restatement and clarification of the problem: State in your own words what you are

going to do.

?Explain assumptions and rationale/justification: Emphasize the assumptions that bear on the problem. Clearly list all variables used in your model.

?Include your model design and justification for type model used or developed.

?Describe model testing and sensitivity analysis, including error analysis, etc.

?Discuss the strengths and weaknesses of your model or approach.

5.The judges will evaluate the quality of your writing in the Solution Paper:

x Conciseness and organization are extremely important.

x Key statements should present major ideas and results.

x Present a clarification or restatement of the problem, as appropriate.

x Present a clear exposition of all variables, assumptions, and hypotheses.

x Present an analysis of the problem, including the motivation or justification for the model that is used.

x Include a design of the model.

x Discuss how the model could be tested, including error analysis and stability (conditioning, sensitivity, etc.).

x Discuss any apparent strengths or weaknesses in your model or approach.

6.Papers must be typed in English, with a readable font of (11 or 12).

7.The solution must consist entirely of written text, and possibly figures, charts, or other

written material only. No non-paper support materials such as computer files or software will be accepted.

8.The Solution Paper must display the team control number and the page number at

the top of every page; for example, use the following page header on each page:

Team # 321Page 6 of 13

9.The names of the students, advisor, or institution should NOT appear on any page of the

electronic solution. The solution should not contain any identifying information other than the team control number.

10.Failure to adhere to any preparation rule is grounds for team disqualification.

D. Print Summary Sheet and Control Sheet:

After the contest begins at 8PM EST on Thursday January 28, 2016, and while the teams are preparing their solutions, the advisor should:

1.Login to the contest web site (go to

https://www.sodocs.net/doc/9217520091.html,/undergraduate/contests/mcm. Click on Advisor Login, then

enter your email address and password).

2.Enter the team member names and confirm that each name is spelled correctly. This

determines how the names will appear on the contest certificates. COMAP will not

make any changes or reprint certificates for any reason.

3.Specify the problem that your team has chosen to solve.

4.Print one copy of the Control Sheet.

5.Print or copy the team Summary Sheet.

III.BEFORE THE CONTEST ENDS:

1.Each team is required to submit an electronic copy of its solution paper by email to

solutions@https://www.sodocs.net/doc/9217520091.html,. Any team member or the advisor may submit this email.

a.Your email MUST be received at COMAP by the email submission deadline of

9PM EST on February 1, 2016.

b.Failure by a team to submit a solution via email by 9PM EST on February 1, 2016

constitutes a violation of the contest rules and will result in that team’s disqualification.

c.No further modifications, enhancements, additions, or improvements may be made to

the team’s solution paper after 8PM EST on February 1, 2016. Any changes to the

solution will constitute a violation of the contest rules and may result in

disqualification.

?MCM Awards (Problem A, B and C)

?The Ben Fusaro Award will be accorded to an especially creative paper and will be chosen from the contest finalists.

?The Frank R. Giordano Award began in 2012. It honors Brig. Gen. (ret) Frank

Giordano who directed the MCM for 20 years. This award goes to a paper that

demonstrates true excellence in the execution of the modeling process.

?ICM Awards (Problem D, E and F)

?The Leonhard Euler Award is presented to a team selected by the head judge of the ICM's Problem D. The criteria are: 1) a paper in the

Meritorious/Finalist/Outstanding rating; 2) contains especially creative and

innovative modeling; and 3) shows good understanding of interdisciplinary

science. The award honors the name of a 18th-century Swiss applied

mathematician, who was known for the breadth of his research applications,

volume of written work, excellent teaching, and interdisciplinarity.

?The Rachel Carson Award honors an American conservationist whose book "Silent Spring" initiated the global environmental movement and whose work spanned

many disciplines concerned with the local and global environments. This award is presented to a team selected by the Head Judge of ICM Problem E for excellence

in using scientific theory and data in its modeling.

?Vilfredo Pareto was an Italian scholar, modeler and problem solver, who at various times was an engineer, sociologist, economist, political scientist, mathematician,

and philosopher. He lived and worked in the late 19th and early 20th centuries. The ICM Pareto Award for outstanding modeling in the Policy Modeling problem

(ICM Problem F) honors the work and legacy of this famous social science

problem solver. In particular for this award, the head judge seeks to highlight a

paper that best models the more dynamic and challenging contextual human

elements that make simplification or refinement of policy models so difficult.

The Institute for Operations Research and the Management Sciences (INFORMS) is the largest society in the world for professionals in the field of operations research (OR), management science (MS), and analytics. INFORMS has long recognized the importance of involving undergraduate students and faculty in an unscripted process of mathematical modeling whose problems contain many of the modern elements seen by its membership.

The MCM/ICM exemplifies these characteristics. Consequently, INFORMS has been an active supporter of the MCM/ICM since its inception.

INFORMS carefully selects and designates a single Outstanding team from each of the six problems - A, B, C, D, E, F - as an INFORMS Outstanding winning team whose modeling and analyses best exemplify the style and content reflected in its membership's professional practice. Each of the INFORMS Outstanding teams receives an engraved plaque for their department's use as a public recognition of the team's achievement. Each student also receives a letter of congratulations from the current INFORMS President, a complimentary one-year INFORMS student membership, a print copy of the award plaque suitable for framing, and an individual cash award. Each associated faculty advisor receives a letter of congratulations and appreciation from the current INFORMS President, along with complimentary one-year access to the full suite of award-winning INFORMS journals.

The Society for Industrial and Applied Mathematics (SIAM) will designate one Outstanding team from each MCM problem as a SIAM winner.

Description of the Award

Student Team Members

Each student member of the winning team will receive a cash award of $500 and three one-year student memberships in SIAM. Team members’ travel expenses will be reimbursed by SIAM up to $650 for domestic travel or $800 for international travel. A one-year student membership in SIAM will be given to each member of non-winning teams judged as "Outstanding" by the official contest judges.

Faculty Adviser

A suitable certificate for the home institutions will be given to the faculty advisers of the winning teams

The Mathematical Association of America (MAA) will designate one Outstanding team from each problem for the MCM as a MAA winner. Each student member of the winning team will receive a certificate. MAA will partial reimburse teams travel expenses to Math Fest so that they may present their paper.

2013年美赛MCM题目A评委点评中文翻译

介绍 今年的焦点问题是如何实现质量和数量的平衡。 在质量方面,尽可能使热量均匀地分布。目标是降低或避免矩形烤盘四个边角发生热量聚集的情况。所以解决热量均匀分布这方面的问题,使用圆形烤盘是最佳的选择。 在数量方面,应该使烤盘充分的占据烤箱的空间。所以我们的目的是使用尽可能多的烤盘来充分占据烤箱的空间,此时矩形烤盘是最佳选择。对于这方面的问题的解决,就要考虑烤盘在烤箱水平截面上所占的比率。 在这个评论中,我们首先描述判断步骤,然后再讨论队伍对于三个问题的求解。下一个话题就是论文的灵敏度和假设,紧随其后讨论确定一个给定方法的优势和劣势。最后,我们简短的讨论一下参考和引用之间的区别。 过程 第一轮的判别被称为“分流轮”。这些初始轮的主要思想是确定论文应被给予更详细的考虑。每篇论文应该至少阅读两次。在阅读一篇论文的时候,评审的主要问题是论文是否包含所有必要的成分,使它成为一个候选人最详细的阅读。在这些初始轮中,评审的时间是有限制的,所以我们要尽量让每一篇论文得到一个好的评判。如果一篇论文解决了所有的问题,就会让评审觉得你的模型建立是合理的。然后评审可能会认为你的论文是值得注意的。有些论文在初轮评审中可能会得到不太理想的评论。 特别值得注意的是,一篇好的摘要应该要对问题进行简要概述,另外,论文的概述和方法,队员之间应该互相讨论,并且具体的结果应该在某种程度上被阐述或者表达出来。在早期的几轮中,一些小细节能够有突出的表现,包括目录,它更便于评委看论文,同时在看论文的时候可能会有更高的期待。 问题求解也很重要。 最后,方法和结果要清晰简明的表达是至关重要的。 另外,在每个部分的开始,应该对那个部分进行一个概述。 在竞赛中,建模的过程是很重要的,同时也包括结论的表达。如果结果没有确切和充分的表达,那么再好的模型和再大努力也是没有用的。 最后的回合 最后一轮阅读的第一轮开始于评委会会议。在这个会议中,评委将进行讨论,他们会分享他们各自认为的问题的关键方面。然后每个评委阅读大量的论文。这些论文来自以前判断轮中平均分配的,论文的分数是各种各样从低到高排列的。 这些论文检查结束之后,评委们又聚到一起讨论,讨论他们认为一篇好的论文应该包括什么。评委们都知道团队们要在限制的时间里完成比赛,这额外的步骤的目的是补偿队伍的局限性和限制强迫队里的成员。 一旦评委同意了一套最低标准,最后回合开始。每一篇论文都被阅读很多次。随着回合的进展,论文的数量逐渐减少,条目越来越多地受到审查.。此外,投入每一篇论文的时间持续上升,在最后一轮,论文仍然是给予最高水平的关注。评审花在论文上的时间增加了,多个评委可以同时阅读同一份论文的复印件.。到了这个时候,论文通常保持优秀的摘要和良好的书面。然后,评委完全集中在建模过程和数学完整性的论文上。 问题 今年的问题可以归结于三个不同的问题。 第一个问题是确定一个给定形状的布朗尼烤盘的热分布情况。

2017美赛六种题型分析及获奖技巧

2017美赛六种题型分析及获奖技巧 六种题型怎么理解 首先,MCM/ICM(2016年起)每年共有6道题,不是6种题,MCM是ABC三题,ICM是DEF三题。对6道题目类型的描述,不是严格的划分,角度和依据都不相同。continuous和discrete是指模型的类型,data insights是指问题数据的特征,operations research/network science和environmental science是指问题涉及到的学科,而environmental science和policy又是指问题本身的背景。这不是按照同一标准对题目进行划分,之间有重叠。最显然的,如果认为continuous和discrete是互补的,那么其他4道题目应该可以分别归入其中某一类。 其次,这些一两个词的描述过于笼统、宽泛,无法体现题目的具体特征,特别是A、B、F题的描述,提供的信息非常少,说了几乎等于没说。continuous、discrete 把所有的模型全包括了。policy范围也太广,人类主宰世界,方方面面都可能涉及政策问题。而且F题也是2016年新增加的,只有2016年一年的题目(难民问题),暂时还看不出来什么规律。 而C题和D题的特征相对具体一些。比如,针对2016年起MCM新增加的C题,COMAP(Consortium for Mathematics and Its Applications)专门发布了一份文档(中文简介)说明其特征。概括起来,MCM的C题与数据有关,虽然称不上大数据,但压缩包也在100MB以上,与MCM/ICM其他题目相比,数据量算是大的(实际上以往MCM/ICM的题目很少给数据),这就要求选这一题的参赛队要熟悉数据处理的基本方法,包括预处理、后处理等,并掌握相应的编程技能或是相关软件的使用方法。模型、方法方面,可能主要集中在统计、模式识别等方向。再比如D题如果是网络科学的问题的话,所用到模型、算法、软件比较集中,有章可循。近几年网络科学是一个热门研究领域,算法、软件包括可视化的软件都很多,如果对这一领域的相关知识和软件都比较熟悉,选题时可以重点关注D 题。 E题环境科学,大体上会集中在环境污染、资源短缺、可持续发展、生态保护等几个方面。对问题的背景有一定的提示作用,但是范围仍然很广,模型、方法没有明显的特征。

培美曲塞测试试卷试题

培美曲塞疾病与药物基础知识测试 一、填空题: 1.肺癌位居肿瘤发病率和死亡率第一位的是。 2.小细胞肺癌 (16.8%)和非 小细胞肺癌(80.4%)。 3.非小细胞肺癌主要分为:鳞状细胞癌、肺腺癌、大细胞肺癌。 4.肺癌的治疗中,以铂类为基础的化疗方案可延长患者生存、提高有效率、提高生活质量, 常用的化疗方案有:EP ,VP/NP ,GP ,TP ,PEM+DDP 等。 5.化疗分类:新辅助化疗、辅助化疗、姑息化疗。 6.新辅助化疗:术前化疗,目的为增加手术机会,减小微转移灶。 7.辅助化疗:术后化疗,目的为减小微转移灶。 8.姑息化疗:用于无法手术晚期恶性肿瘤,目的为减小症状,提高患者生活质量,延长患 者生存时间。可分为一线化疗、及二线、二线以后化疗。 9.培美曲塞是抗代谢类抗肿瘤药。 10.培美曲塞抗肿瘤作用机制:抑制胸苷酸合成酶(TS)、二氢叶酸还原酶(DHFR)、甘氨酰 胺甲酰基转移酶(GARFT),从而抑制嘧啶和嘌呤的合成,三管齐下达到多靶点抗肿瘤。 11.培美曲塞产品规格:500mg、100mg。 12.培美曲塞性状:类白色或微黄色疏松块状物或粉末。 13.培美曲塞说明书适应症:适用于与顺铂联合治疗无法手术的恶性胸膜间皮瘤。 14.培美曲塞美国FDA批准适应症: (1)与顺铂联用治疗恶性胸膜间皮瘤。(2004年2月批准) (2)单药用于NSCLC二线治疗。(2004年8月批准)

(3)与顺铂联用用于非鳞癌型NSCLC一线治疗。(2008年9月批准) (4)用于非鳞癌型NSCLC维持治疗。(2009年7月批准) 15.目前培美曲塞在以其高效低毒在临床广泛使用,已经不局限在恶性胸膜间皮瘤和肺癌,在 卵巢癌、胃癌、肠癌等实体瘤都有相关报道。因此奥天成可推广科室较多,主要推广科室:肿瘤科、呼吸科、胸外科、放疗科;次要推广科室:妇瘤科、胃肠外科、乳腺外科、介入科等 16.培美曲塞联合顺铂方案使用用法用量:奥天成500mg/m2,静脉滴注,30分钟后顺铂75 mg/m2静脉滴注。该方案每21天为一个周期。 17.培美曲塞主要毒副反应:骨髓抑制、恶心呕吐、乏力、皮疹、胸痛。 18.培美曲塞主要通过肾脏代谢,对正常肝肾功能无影响,但是血清肌酐清除率<45ml/min 的患者,不能使用。 19.培美曲塞产品定位:NSCLC一线治疗首选。 二、简答题 1.培美曲塞使用过程中为了降低如皮疹等毒副反应的发生率和严重程度。需要补充叶酸和维 生素,请详细说明补充方法。 答: (1)预服地塞米松,4mg口服Bid,培美曲塞给药一天、给药当天和给药后一天,连用3天。 (2)叶酸补充350μg-1000μg,推荐400μg。培美曲塞第一次给药前7天开始服用,一直持续整个治疗过程。 (3)VitB12:1000μg,第一次给药前7天内肌注一次,以后每3个周期肌注一次。 补充叶酸和维生素时不能同时使用非甾体类抗炎药 2.培美曲塞作为抗代谢类抗叶酸的药物为什么还要补充叶酸和维生素?补充叶酸和维生素 会不会降低疗效? (1)叶酸在人体正常细胞内的生物合成中起关键作用,正常组织需要叶酸来维持,正常人每天需要摄入叶酸350μg -1000μg。培美曲塞通过抑制三种叶酸依赖性酶来抑制 DNA合成,会导致正常细胞叶酸严重缺乏,带来严重不良反应。 (2)适量补充叶酸和维生素在保护了正常组织和细胞,但是由于肿瘤细胞增殖速度比正常细胞快,对叶酸和维生素的需求也远大于正常细胞,即使补充叶酸也不够肿瘤细

维持治疗

李DG,男,49岁,因咳嗽和腰背部疼痛2月余于2012年7月到我院就诊,CT检查发现右肺下叶占位,全身骨扫描检查(ECT)提示多发骨转移,7月30 日做CT引导下穿刺活检,病理报告为低分化腺癌。 于2012.8.4开始给予培美曲赛联合顺铂的两药联合化疗,辅以双膦酸盐静脉注射以控制骨转移,化疗结束一周后咳嗽和腰背部疼痛即有所减轻。之后每3周一次重复原方案化疗,患者分别于8.25、9.16和10.7接受第2、3和4周期化疗。完成2周期化疗后做胸部CT复查,肿瘤明显缩小,疗效评价为部分缓解。化疗4周期后做CT检查,肿瘤进一步缩小。鉴于已获得良好疗效,患者身体状况较好,愿意再接受原方案化疗,遂于2012.10.30-11.21继续采用原方案完成第5和第6周期化疗,再做CT复查,肿瘤大小较前没有变化。双膦酸盐每月一次静脉滴注。 6个周期双药联合化疗结束后,患者自觉乏力较前明显加重,进食减少伴,近2个月体重下降2公斤,虽有接受进一步治疗的意愿,但对化疗的副作用产生恐惧。经与患者和家属交流和讨论,同意接受副作用较轻的培美曲赛单药维持治疗,于2012.12.17开始第一次培美曲赛化疗,患者耐受良好,之后分别于 2013-1-10、2-17、3-17、4-17、5-13,6-9,7.8完成了第2-8周期的培美曲赛单药维持化疗,平均每月一次共8个周期,期间复查肿瘤大小没有明显变化。目前患者一般状况良好,在开始维持治疗后不久即恢复正常工作。以下是该患者治疗期间血清肿瘤标志物癌胚抗原(CEA)的变化。从图中可以看出,CEA在最初化疗几周期快速下降,之后下降速度明显放慢,维持治疗期间仍逐渐下降。最后4次(4个月内每月一次检测)虽有波动,但趋势是进一步下降。 从该例患者的治疗经过,可以总结出以下几点以供大家参考: 1. 该肺癌患者从化疗(诱导+维持)中明显获益。目前的化疗能使约1/3的肺癌获得部分缓解,使1/2患者的肿瘤稳定(瘤体长径缩小不足30%,增长在20%以下),其余1/4患者虽经化疗但疾病进展(肿瘤长径增长>20%)。如4-6周期化疗结束后终止治疗,约2-3个月就能看到肿瘤进展,化疗的缓解期较短。晚期肺癌经单纯化疗后的中位生存期为8-10月。该患者化疗效果明显,目前肿瘤体积约为治疗前时的1/6~1/8大小,从检查结果来看到目前为止肿瘤仍没有形成耐药,肿瘤缓解期已超过1年。该患者年轻、身体状态良好,患者对所使用的化疗药物耐受较好。培美曲塞是不良反应相对较轻的第三代化疗药,无论联合或单用,都显示出较好的耐受性和不俗的疗效。 2. 传统的评价疗效参照的是国际上通用的实体瘤疗效评价标准(RECIST),依据肿瘤最大径的变化来评估:完全缓解(肿瘤完全消失);部分缓解(肿瘤长径缩短30%以上);稳定(瘤体长径缩小不足30%,增长<20%以下);疾病进展(肿瘤长径增长>20%)。目前还很少有人用血清中肿瘤标志物来评价肺癌和其他一些实体瘤的疗效。但通过对观察该患者血清CEA的动态变化和肿瘤大小的变化(CT 检查),发现CEA下降与肿瘤的缩小是同步的,当肿瘤缩小到一是程度后CT检查很难发现肿瘤大小的细微改变,但CEA的数值一直在下降。当肿瘤发生耐受后,首先表现出来一定是CEA等标志物的上升,只有肿瘤生长一段时间并且瘤体增加一定幅度(长径增长超过20%)后才能被CT检查出来。与CT检查相比,在评价
