This is an open access book. This textbook contains about 200 fully solved problems in analytical and numerical methods for nonlinear osccillations. These comprise all the end-of-chapter problems in Ali H. Nayfeh and Dean T. Mook’s famous textbook Nonliear Oscillations. Mathematical software are adopted to make those solutions more accessible from a graphical point of view. This book can be adopted as a supplement to course work study for graduates or senior undergraduates. Since many exercise problems are adapted from scientific research papers, this book also has a good reference value for scientists and engineers who work in nonlinear vibration.

This book systematically presents these findings for the first time, focusing on the composition, force mode, structural characteristics, performance advantages, and calculation methods for each new structural system, and comparing each one with traditional structural systems. In view of the persistent problems in the current equivalent cast in situ precast concrete structural systems and the development of non-equivalent cast in situ precast concrete structure systems, Southeast University and Harbin Institute of Technology have conducted extensive research and proposed several new types of precast concrete structural systems. Their findings in this regard can promote the development of basic theories and technologies for building industrialization, accelerate the advancement of China''s building industrialization, promote the application of precast building technology, and realize the concept of green building.

Standards-based reform is a key feature of U.S. education policy. Several decades ago, scholars posited that if states set ambitious standards and then aligned curriculum, assessments, and professional development (PD) to those standards, teaching and learning would improve. However, the focus on establishing standards has often overshadowed the important idea that standards are effective only if the other inputs in an instructional system (e.g., curriculum, assessments, PD) are in alignment with those standards and coherent with each other. Without that alignment and coherence, teachers may perceive different messages about what to teach and how to teach it. At worst, those messages can conflict, leading to both fragmented instruction and reduced learning opportunities. In this report, researchers aim to contribute to evidence on the extent to which an instructional system is coherent and provides consistent and clear messages to teachers about instruction, including messages about how to address the learning needs of traditionally underserved students. The research team uses survey responses from a nationally representative sample of public school kindergarten through grade 12 (K-12) English language arts and mathematics teachers to present a portrait of instructional system coherence in schools across the country during the 2021-2022 school year.

Since March 2020, the COVID-19 pandemic has placed unprecedented stresses on the public education system in the United States. Many of these challenges have been operational in nature. Existing research on COVID-19 and teaching has largely focused on teachers' practices and experiences. What has not been examined in the same depth is the guidance that teachers received about instruction during the pandemic and the ways guidance changed from before the pandemic. This work is important, especially as the pandemic continues to affect the provision of in-person learning in the 2021-2022 school year. It is also important to understand how state and district efforts to improve instruction have fared during this unprecedented educational disruption. Developing a coherent, standards-aligned instructional system is challenging for education leaders and teachers in the best of times, and it may be especially difficult to achieve as the pandemic continues to affect public schooling. This report examines issues of instructional system coherence during the 2020-2021 school year, and how teachers' perceptions compared with the 2019-2020 school year. The authors investigate teachers' perceptions of the (1) guidance they received about English language arts (ELA) instruction, (2) guidance around addressing the needs of traditionally underserved students, (3) coherence of their school's ELA instructional system, and (4) presence of contextual conditions identified through literature as supporting coherence. The authors also explore variation in these findings across grade spans, instructional modes (in-person, remote, hybrid), and focal states (Louisiana, Massachusetts, Rhode Island, and Tennessee).

The RAND Corporation launched the Gun Policy in America initiative in January 2016 with the goal of creating objective, factual resources for policymakers and the public on the effects of gun laws. The primary goal was to create resources where policymakers and the general public can access unbiased information that facilitates the development of fair and effective gun policies, and all resources are accessible on the project website. Responding to feedback from teachers and colleagues, RAND researchers developed a unit plan centered on those resources. The unit is designed to help high school educators and students-who are increasingly interested in joining the conversation about gun policy and mobilized to respond to gun violence-access the high-quality, evidence-based materials on the website. The researchers'' overarching goals in developing the unit are to guide students to understand existing research related to gun policy and deeply consider the complexity of gun policy-related issues. The lessons and activities engage students in critically reading and synthesizing research evidence and expert opinions, and the unit culminates in the students applying this information to present an argument for or against implementing a specific gun policy.

#1 Choice for 3rd-year and 4th-year College Chinese. With free video clips and audio downloads. Written by professors from top Universities in the U.S. In simplified and traditional characters. In this new edition, we kept the topics of the first eleven lessons from the previous version but made small modifications to the dialogues and texts so they are more up to date and relevant. Three new topics are added: Ordinary People and Children of the Elite (Lesson 4), Democracy and the Modern Life (Lesson 6) and Influence of Contemporary Arts (Lesson14). This made both Part 1 and Part 2 of this new edition contain seven topics. Adding these three new lessons allows students to discuss more current topics. It also better distributes the amount of new vocabulary across each lesson and creates new contexts for the students to review and practice them. In Part 2, the 7 topics are: Leftover Population in the Marriage Market, Studying Abroad and Emigrating, Chinese Idioms and Chinese Cross Talks, Colloquial Idioms and Satirical Rhymes, Health and Gastronomy, From Revolution Songs to Pop Music and The Influence of Arts. Notes of reviewed vocabulary from previous lessons are added to the listening dialogues, reading texts, sample sentences and workbook exercises. This will make it easier for students to preview and review each lesson. At the same time, it will give instructors flexibility to select or shuffle the lessons to best fit their needs. We also included the transcripts of the dialogues at the end of the listening section and added more speaking activities related to the students'' daily life. We also filmed a skit for each lesson to teach action verbs and narrative abilities and added warm-up activities, culture notes and authentic materials to each topic. In the workbook, vocabulary exercises are given in chunks to help students review vocabulary in corresponding stages. Exercises in Chinese characters are also given to help student memorize them more systematically and to strengthen their concept of character-based lexicon learning.

This book proposes a method for calculating China’s debt based on a quantitative econometric analysis. This is conducted by measuring the relationship between China’s debt size and economic growth. The conclusion that is reached is as follows: China’s current debt has already exceeded the inflection point, and that means that it is now having an adverse effect on its economic performance. The book also focuses on China''s debt problems as a whole, highlighting debt issues faced by different entities and industries, as well as the ratio and structure of the virtual and real economies. The contents are presented in three major principles: theory, oriented,data, and oriented policy.

School principals are charged with complex responsibilities that can include developing a school vision and culture, supporting teacher effectiveness, managing challenges and crises, communicating with the greater community, and more. However, recent research and surveys of school administrators indicate that principal preparation programs do not adequately prepare graduates to cope with school realities. In response to concerns about the state of initial principal preparation, The Wallace Foundation established the University Principal Preparation Initiative (UPPI), a four-year effort to redesign seven universities' principal preparation programs according to evidence-based principles and practices. Each university collaborates on the redesign with high-need school districts and a state partner, and is supported by a mentor program. The report summarized in this document focuses on the implementation of UPPI in its first year, from fall 2016 to fall 2017. The authors report on UPPI progress and identify cross-cutting themes in the UPPI implementation effort that can help other university principal preparation programs and their partners undertake their own principal preparation system improvement efforts.

Wood-framed construction is one of the main building types for residential buildings in North America because of their features such as light-weight, easily built and environmental friendly. However, prolonged exposure to moisture during construction and in service is a durability concern for wood framed envelopes. As building energy consumption has gained increasing attention in recent years, the majority of building codes in North America require higher insulation levels in building envelopes to improve the building energy efficiency. However, the highly insulated wood framed envelopes may have higher risk of moisture problems such as mold growth and wood decay depending on their configurations. Hygrothermal simulation programs have been widely used for evaluating hygrothermal performance of wood framed envelopes. However, the uncertainties of the input parameters may result in a discrepancy between simulation results and the real performance of the wood framed envelopes, thereafter, unable to reveal the actual risks of moisture problems. Stochastic modelling has been used to investigate the uncertainties of the input parameters and their influence, however, the stochastic parameters were only limited to material properties and boundary conditions in previous studies without considering the moisture loads such as air leakage and rain leakage. This thesis focuses on developing a methodology to evaluate the hygrothermal performance of wood framed envelopes under various moisture loads using stochastic approach. A stochastic modelling framework is developed based on a well-developed hygrothermal simulation program- DELPHIN and a robust programming platform- MATLAB. Latin Hypercube Sampling technique and Factorial Design Experiment are combined to organize the stochastic material properties, boundary conditions and moisture loads, and generate stochastic models. Uncertainty and sensitivity analysis are performed based on the stochastic input parameters and results to evaluate the moisture content level and mold growth risk, as well as the sensitivity of the moisture performance to each influential factor. The developed stochastic modelling framework is applied to analyze the hygrothermal performance of Cross Laminated Timber (CLT) wall assemblies and compared with parametric study to demonstrate the advantages of stochastic approach. Then, the hygrothermal performance of the highly insulated wood framed walls (deep cavity walls and exterior insulated walls) are analyzed using the stochastic modelling framework. It is found that the exterior insulated walls have lower mold growth risk than deep cavity walls, and the wall with high permeance exterior insulation (mineral wool) is safer than that with low permeance exterior insulation (polyisocyanurate) in terms of mold growth. The moisture performance of the walls is more sensitive to moisture loads than to material properties, and the significance of the moisture loads (air leakage and rain leakage) depends on climate condition. The thresholds of air leakage rate and rain deposition factor are obtained for the highly insulated wood framed walls to avoid mold growth risk. The design guidelines are formulated for energy efficient and durable wood framed envelopes. The developed stochastic modelling framework can be also applied to other moisture damage risk analysis such as wood decay and the damage caused by freeze/thaw cycles.

Research in carbon nanotubes has reached a horizon that is impacting a variety of fields, such as nanoelectronics, flat panel display, composite materials, sensors, nanodevices, and novel instrumentation. The unique structures of the nanotubes result in numerous superior physical and chemical properties, such as the strongest mechan ical strength, the highest thermal conductivity, room-temperature ballistic quantum conductance, electromechanical coupling, and super surface functionality. Several books are available that introduce the synthesis, physical and chemical properties, and applications of carbon nanotubes. Among the various analytical techniques, high-resolution transmission electron microscopy (HRTEM) has played a key role in the discovery and characterization of carbon nanotubes. It may be claimed that carbon nanotubes might not have been discovered without using HRTEM. There is a great need for a book that addresses the theory, techniques, and applications of electron microscopy and associated techniques for nanotube research. The objective of this book is to fill this gap. The potential of HRTEM is now well accepted in wide-ranging communities such as materials science, physics, chemistry, and electrical engineering. TEM is a powerful technique that is indispensable for characterizing nanomaterials and is a tool that each major research institute must have in order to advance its research in nanotechnology.

This book explores the mechanisms and significance of China’s private economy participating in poverty alleviation. By basing its analysis on theories of development economics and public economics, the book stresses practical significance and abandons unreasonable assumptions. It uses a systematic set of statistical analysis tools and descriptive statistics to provide a multidimensional and highly visual format. Beyond the traditional qualitative comparison of countries, it also introduces quantitative comparison. Considering the increasing concern and curiosity about China’s booming economy and rising private sector, the book is highly topical, offering readers theoretical insights into China’s poverty alleviation mechanisms and essential information on the role played by the private economy in social and economic development.u200b

Elastic and inelastic scattering in transmission electron microscopy (TEM) are important research subjects. For a long time, I have wished to systematically summarize various dynamic theories associated with quantitative electron micros copy and their applications in simulations of electron diffraction patterns and images. This wish now becomes reality. The aim of this book is to explore the physics in electron diffraction and imaging and related applications for materials characterizations. Particular emphasis is placed on diffraction and imaging of inelastically scattered electrons, which, I believe, have not been discussed exten sively in existing books. This book assumes that readers have some preknowledge of electron microscopy, electron diffraction, and quantum mechanics. I anticipate that this book will be a guide to approaching phenomena observed in electron microscopy from the prospects of diffraction physics. The SI units are employed throughout the book except for angstrom (A), which is used occasionally for convenience. To reduce the number of symbols used, the Fourier transform of a real-space function P''(r), for example, is denoted by the same symbol P''(u) in reciprocal space except that r is replaced by u. Upper and lower limits of an integral in the book are (-co, co) unless otherwise specified. The (-co, co) integral limits are usually omitted in a mathematical expression for simplification. I very much appreciate opportunity of working with Drs. J. M. Cowley and J. C. H. Spence (Arizona State University), J.

As a new member of the helper T cell subsets, Th17 cells have triggered more and more interest in exploring their development, regulation, function and therapeutic manipulation in distinct context since they were identified in 2005. This also causes a lot of confusion and debate about the generation and function of Th17 cells, especially their activity in the tumor immunopathology as our understanding grows. However, it is worth asserting that the most confusing part arises from the Th17-associated cytokines including IL-17 and IL-23 rather than the Th17 cells. IL-17 cytokine is not synonymous with Th17-cell subset, although IL-17 is the lineage-signature cytokine for Th17 cells. We will discuss the generation, cytokine profile, genetic control, plasticity and stemness of Th17 cells and address the role of Th17 cells and their associated cytokines in tumor immunity, and further explore the potential immunotherapy by targeting Th17 cells and their cytokines.

The fundamental principle of piezotronics and piezo-phototronics were introduced by Wang in 2007 and 2010, respectively. Due to the polarization of ions in a crystal that has non-central symmetry in materials, such as the wurtzite structured ZnO, GaN and InN, a piezoelectric potential (piezopotential) is created in the crystal by applying a stress. Owing to the simultaneous possession of piezoelectricity and semiconductor properties, the piezopotential created in the crystal has a strong effect on the carrier transport at the interface/junction. Piezotronics is for devices fabricated using the piezopotential as a “gate” voltage to control charge carrier transport at a contact or junction. The piezo-phototronic effect uses the piezopotential to control the carrier generation, transport, separation and/or recombination for improving the performance of optoelectronic devices, such as photon detector, solar cell and LED. The functionality offered by piezotroics and piezo-phototronics are complimentary to CMOS technology. There is an effective integration of piezotronic and piezo-phototronic devices with silicon based CMOS technology. Unique applications can be found in areas such as human-computer interfacing, sensing and actuating in nanorobotics, smart and personalized electronic signatures, smart MEMS/NEMS, nanorobotics and energy sciences. This book introduces the fundamentals of piezotronics and piezo-phototronics and advanced applications. It gives guidance to researchers, engineers and graduate students.
