Iran supports a great share of biodiversity and floristic endemism for Fritillaria spp. (Liliaceae): A review.

Iran supports a great share of exotic and/or endemic plant genera and species. The genus Fritillaria (Liliaceae) is a precious part of this botanical richness with 19 species, of which 10 are endemic to the country. However, signs are mounting that the country is truly at a crossroads when it comes to preservation of this national wealth. In this regard, an effective conservation strategy should thoroughly consider the classification of Fritillaria, as conservation practices are compromised by knowledge gaps in systematics and taxonomy. As published studies on Fritillaria in Iran have been sporadic and limited in scope, the aim of this review is to provide information necessary to help bridge these information gaps. Our objective is to facilitate increased understanding of the geographic, taxonomic, cytogenetic and phylogenetic status of Iranian Fritillaria, which is vital to meeting the goal of sustainable conservation of the genus in Iran and neighboring areas

Evaluating and Comparing the Views of Teachers and Students about the Criteria of a Good Professor at Mashhad University of Medical Sciences, Iran

Background & Objective: The main goal of university includes educating specialists needed for society, promotion and development of the knowledge, developing research, and providing the background for society development. Undoubtedly, professor is one of the main and effective factors in high education quality, and training specialist workers requires strong faculty members that are experienced and skilled in various educational courses. We decided to utilize two, professor and student, groups opinions about the indices of a good university teacher. Methods: In this descriptive-analytic and cross-sectional research, 240 professors and 899 students of Mashhad University of Medical Sciences, Iran, were selected by hierarchical and simple random sampling methods. The data were gathered by a researcher-made valid and reliable questionnaire. Results: Teachers Characteristics for a good professor were respectively: Scholarships, communication skills, teaching skills, evaluation skills, and Physical characteristics and appearance of the teachers. Students Characteristics for a good professor, were respectively: communication skills, Scholarships, teaching skills, evaluation skills then Physical characteristics and appearance of the teachers. In the professors, ANOVA test showed there was a significant relationship between the work experience, rank and social field study of teachers and Priority communication skills, scholarship, teaching methods, evaluation and faculty characteristics (p <0.05). In the students, ANOVA test showed there was a significant relationship between major and semester students and Priority communication skills, scholarship and faculty characteristics(p<0.05(. Conclusion: The comparability between two groups in teaching and evaluation domains indicates that there is a good relationship between them; though, this mutual relationship can facilitate learning, then increase students’ consent, and finally increscent educational quality. On the other hand. Giving high priority to professors’ personal characteristics and relationship skills by students shows that, students put more importance on mutual relationship as an educational background.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks

A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance p(T)(miss) in transverse momentum. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). Search regions are defined in terms of the multiplicity of bottom quark jet and top quark candidates, the p(T)(miss) , the scalar sum of jet transverse momenta, and themT2 mass variable. No statistically significant excess of events is observed relative to the expectation from the standard model. Lower limits on the masses of supersymmetric particles are determined at 95% confidence level in the context of simplified models with top quark production. For a model with direct top squark pair production followed by the decay of each top squark to a top quark and a neutralino, top squark masses up to 1020 GeVand neutralino masses up to 430 GeVare excluded. For amodel with pair production of gluinos followed by the decay of each gluino to a top quark-antiquark pair and a neutralino, gluino masses up to 2040 GeVand neutralino masses up to 1150 GeVare excluded. These limits extend previous results.Peer reviewe
