Examination of the U.S. Air Force's Science, Technology, Engineering, and Mathematics (STEM) Workforce Needs in the Future and its Strategy to Meet Those Needs
by National Research Council of the National AcademiesThe Air Force requires technical skills and expertise across the entire range of activities and processes associated with the development, fielding, and employment of air, space, and cyber operational capabilities. The growing complexity of both traditional and emerging missions is placing new demands on education, training, career development, system acquisition, platform sustainment, and development of operational systems. While in the past the Air Force's technologically intensive mission has been highly attractive to individuals educated in science, technology, engineering, and mathematics (STEM) disciplines, force reductions, ongoing military operations, and budget pressures are creating new challenges for attracting and managing personnel with the needed technical skills. Assessments of recent development and acquisition process failures have identified a loss of technical competence within the Air Force (that is, in house or organic competence, as opposed to contractor support) as an underlying problem. These challenges come at a time of increased competition for technical graduates who are U.S. citizens, an aging industry and government workforce, and consolidations of the industrial base that supports military systems. In response to a request from the Deputy Assistant Secretary of the Air Force for Science, Technology, and Engineering, the National Research Council conducted five fact-finding meetings at which senior Air Force commanders in the science and engineering, acquisition, test, operations, and logistics domains provided assessments of the adequacy of the current workforce in terms of quality and quantity.

Examples in Structural Analysis
by William M.C. McKenzie Binsheng ZhangThis third edition of Examples in Structural Analysis uses a step-by-step approach and provides an extensive collection of fully worked and graded examples for a wide variety of structural analysis problems. It presents detailed information on the methods of solutions to problems and the results obtained. Also given within the text is a summary of each of the principal analysis techniques inherent in the design process and where appropriate, an explanation of the mathematical models used. The text emphasises that software should only be used if designers have appropriate knowledge and understanding of the mathematical assumptions, modelling and limitations inherent in the programs they use. It establishes the use of hand-methods for obtaining approximate solutions during preliminary design and an independent check on the answers obtained from computer analysis. What is New in the Third Edition: A new chapter covers the analysis and design of cables and arches subjected to concentrated loads and uniformly distributed loads. For cables without or with simply supported pinned trusses or steel girder beams through equally spaced hangers, tension forces, support reactions, sags and slopes in cables are determined. For two-pinned or three-pinned arches with parabolic, arched and semi-circular shapes, axial forces, radial shear forces and bending moments at various sections of arches are determined. An existing chapter has been expanded to the construction and use of influence lines for pin-pointed trusses and lattice girders. Also, the chapter Direct Stiffness Methods has been revisited and amended.

The Exceptions: Nancy Hopkins and the fight for women in science
by Kate Zernike&‘Outstanding&’ Bonnie Garmus, bestselling author of Lessons in ChemistryThe remarkable untold story of how a group of sixteen determined women used the power of the collective and the tools of science to inspire ongoing radical change. This is a triumphant account of progress, whilst reminding us that further action is needed. These women scientists entered the work force in the 1960s during a push for affirmative action. Embarking on their careers they thought that discrimination against women was a thing of the past and that science was a pure meritocracy. Women were marginalized and minimized, especially as they grew older, their contributions stolen and erased. Written by the Pulitzer Prize-winning journalist who broke the story in 1999 for The Boston Globe, when the Massachusetts Institute of Technology made the astonishing admission that it discriminated against women on its faculty, The Exceptions is an intimate narrative which centres on Nancy Hopkins – a surprisingly reluctant feminist who became a hero to two generations of women in science. In uncovering an erased history, we are finally introduced to the hidden scientists who paved the way for collective change.
The Exceptions: Nancy Hopkins, MIT, and the Fight for Women in Science
by Kate ZernikeA New York Times Notable Book As late as 1999, women who succeeded in science were called &“exceptional&” as if it were unusual for them to be so bright. They were exceptional, not because they could succeed at science but because of all they accomplished despite the hurdles. &“Gripping…one puts down the book inspired by the women&’s grit, tenacity, and brilliance.&” —Science &“Riveting.&” —Siddhartha Mukherjee, author of The GeneIn 1963, a female student was attending a lecture given by Nobel Prize winner James Watson, then tenured at Harvard. At nineteen, she was struggling to define her future. She had given herself just ten years to fulfill her professional ambitions before starting the family she was expected to have. For women at that time, a future on the usual path of academic science was unimaginable—but during that lecture, young Nancy Hopkins fell in love with the promise of genetics. Confidently believing science to be a pure meritocracy, she embarked on a career. In 1999, Hopkins, now a noted molecular geneticist and cancer researcher at MIT, divorced and childless, found herself underpaid and denied the credit and resources given to men of lesser rank. Galvanized by the flagrant favoritism, Hopkins led a group of sixteen women on the faculty in a campaign that prompted MIT to make the historic admission that it had long discriminated against its female scientists. The sixteen women were a formidable group: their work has advanced our understanding of everything from cancer to geology, from fossil fuels to the inner workings of the human brain. And their work to highlight what they called &“21st-century discrimination&”—a subtle, stubborn, often unconscious bias—set off a national reckoning with the pervasive sexism in science. From the Pulitzer Prize–winning journalist who broke the story, The Exceptions chronicles groundbreaking science and a history-making fight for equal opportunity. It is the &“excellent and infuriating&” (The New York Times) story of how this group of determined, brilliant women used the power of the collective and the tools of science to inspire ongoing radical change. And it offers an intimate look at the passion that drives discovery, and a rare glimpse into the competitive, hierarchical world of elite science—and the women who dared to challenge it.

Excitation Spectra of Square Lattice Antiferromagnets
by Bastien Dalla PiazzaThis thesis presents a qualitative advance in our understanding of quantum effects in layered magnetic materials. The nearest neighbor Heisenberg ferromagnetic ranks among the oldest and most fundamental models of quantum many body effects. It has long been established that in one dimension quantum fluctuations lead to a quantum disordered ground state with fractional excitations called spinons. " In two dimensions, the ground state of the Heisenberg model displays static order and to first approximation the dynamics can be described as semi-classical spin waves. Through theoretical advances the author demonstrates that at high energy around particular points in reciprocal space these semi-classical spin-waves deconfine into fractional excitations akin to the one-dimensional spinons. He thereby provides the first explanation of a long-standing experimental observation. In the second half of his thesis Bastien Dalla Piazza develops a unified description of the magnetic excitation spectra of a range of cuprate parent compounds to the high temperature superconductors.
Exciton Dynamics in Lead Halide Perovskite Nanocrystals: Recombination, Dephasing and Diffusion (Springer Theses)
by Bernhard Johann BohnLess than a decade ago, lead halide perovskite semiconductors caused a sensation: Solar cells exhibiting astonishingly high levels of efficiency. Recently, it became possible to synthesize nanocrystals of this material as well. Interestingly; simply by controlling the size and shape of these crystals, new aspects of this material literally came to light. These nanocrystals have proven to be interesting candidates for light emission. In this thesis, the recombination, dephasing and diffusion of excitons in perovskite nanocrystals is investigated using time-resolved spectroscopy. All these dynamic processes have a direct impact on the light-emitting device performance from a technology point of view. However, most importantly, the insights gained from the measurements allowed the author to modify the nanocrystals such that they emitted with an unprecedented quantum yield in the blue spectral range, resulting in the successful implementation of this material as the active layer in an LED. This represents a technological breakthrough, because efficient perovskite light emitters in this wavelength range did not exist before.
Excitonic and Photonic Processes in Materials
by Jai Singh Richard T. WilliamsThis book is expected to present state-of-the-art understanding of a selection of excitonic and photonic processes in useful materials from semiconductors to insulators to metal/insulator nanocomposites, both inorganic and organic. Among the featured applications are components of solar cells, detectors, light-emitting devices, scintillators and materials with novel optical properties. Excitonic properties are particularly important in organic photovoltaics and light emitting devices, as also in questions of the ultimate resolution and efficiency of new-generation scintillators for medical diagnostics, border security and nuclear non proliferation. Novel photonic and optoelectronic applications benefit from new material combinations and structures to be discussed.
