Verhulst limited growth model with unknown parameters of growth is considered. These parameters are defined by discrete experiment data. This inverse problem is solved with using gradient method with interpolation of data and without it. Approximation of the delta-function is used for the latter case. As an example the bacteria population *** is considered.
In exemplar-based inpainting approach, the priority computation is excessively biased towards those patches which are on the continuation of strong edges, which may lead to unreasonable filling order. Furthermore, the...

A critical juncture in the undergraduate STEM education pathway is the first two years of college when the majority of attrition occurs because students experience many academic challenges in gatekeeping courses. Among many factors to this failure, an important one is attributed to the lack of engaging pedagogy inside and outside classrooms. Through this NSF WIDER Program sponsored planning project, a team of faculty and administrators at Alabama Agricultural and Mechanical University (AAMU) are implementing evidence-based instructional practices in foundation courses in STEM curricula. Recognizing that it is essential to implement effective pedagogy in gateway courses where most attrition occurs, this project has conducted a pilot study, which focuses on: (1) collecting baseline data about the extent to which evidence-based practices are currently being used in STEM gateway courses;(2) redesigning three foundational gateway courses in electrical engineering, computerscience and mathematics by applying evidence-based teaching strategies-student-centered problem-based teaching(SC-PBT), example-based teaching, and just-in-time teaching (JITT);(3) incorporating classroom and laboratory activities that require active student engagement, conceptual understanding, critical thinking, and problem-solving;and (4) Employing model students to lead Supplementary Instruction (SI) courses with evidence-based peer-to-peer learning strategies. The student assessment data indicated the effectiveness of the evidence-based instructional practices, the SI peer-to-peer learning strategies, as well as existing engagement challenges. In addition, positive feedback was obtained from the student survey data on the redesigned courses. The broader impact of this project is twofold. First, data generated through assessment and evaluation is expected to support the theoretical rationale that systematic change in STEM education must include a wide spectrum of stakeholders (administrators, facul

We calculate the amplitude of the πη photoproduction on the proton and the associated cross sections. The primary objective of the model is to describe the photoproduction of the isovector resonances in the πη channel which is important in the context of elucidating the nature of the scalar a0(980) meson. The model can be also applied to description of the photoproduction of tensor isovector resonance a2(1320).

Evaluating student performance in learning teams is challenging. This chapter reviews the student learning team and peer evaluation literature. The authors share the results of their experience using four rubrics for peer evaluation in student learning teams. Student learning teams involve forming students into teams for the semester to enhance their active learning. A portion of the course grade is dedicated to team quizzes, activities, and projects. The authors conclude that peer evaluation data should be used both formatively and summatively to enhance team cohesion and accountability and provide their preferred rubric for the peer evaluation process. Usage of forced differentiation in peer evaluation is discussed. A mathematical formula for calculating the impact of peer evaluations in learning teams on course or team project grades is presented.

Two-player N-strategy symmetric noncooperative games are considered. A general form of gate operators is found using group-theoretical methods. The stability group of initial state is introduced and calculated in the case of three strategies games. Its role in determining the Nash equilibria for maximally entangled games is stressed.
