Allegations of fraud, conflict of interest, and other ethical
dilemmas have troubled the scientific community. With increasing
frequency, graduate programs in the biomedical sciences are
offering formalized training in the principles of responsible
scientific conduct. Scientific Integrity, Fourth Edition covers
essential topics related to the conduct of scientific
investigation, such as guidelines, policies, standards, and codes
and contains highly relevant interactive case studies. This
textbook covers broad areas of scientific integrity and meets the
needs of students and scientists working in the biomedical
sciences. Newly updated case studies that parallel the material
presented in the chapters are included to illustrate the diversity
of issues that have been identified under the umbrella of
scientific integrity. All chapters have been thoroughly updated,
especially with regard to the new technologies in data discovery
and sharing, and the latest NIH and international best practices
guidelines. This title is published by the American Society of
Microbiology Press and distributed by Taylor and Francis in rest of
world territories.
This book lays out a new, general theory of light propagation and
imaging through Earth's turbulent atmosphere. Current theory is
based on the - now widely doubted - assumption of Kolmogorov
turbulence. The new theory is based on a generalized atmosphere,
the turbulence characteristics of which can be established, as
needed, from readily measurable properties of point-object, or
star, images. The pessimistic resolution predictions of Kolmogorov
theory led to lax optical tolerance prescriptions for large
ground-based astronomical telescopes which were widely adhered to
in the 1970s and 1980s. Around 1990, however, it became clear that
much better resolution was actually possible, and Kolmogorov
tolerance prescriptions were promptly abandoned. Most large
telescopes built before 1990 have had their optics upgraded (e.g.,
the UKIRT instrument) and now achieve, without adaptive optics
(AO), almost an order of magnitude better resolution than before.
As well as providing a more comprehensive and precise understanding
of imaging through the atmosphere with large telescopes (both with
and without AO), the new general theory also finds applications in
the areas of laser communications and high-energy laser beam
propagation.
This book presents the theory of quantum effects used in metrology
and results of the author’s own research in the field of quantum
electronics. The book provides also quantum measurement standards
used in many branches of metrology for electrical quantities, mass,
length, time and frequency. This book represents the first
comprehensive survey of quantum metrology problems. As a scientific
survey, it propagates a new approach to metrology with more
emphasis on its connection with physics. This is of importance for
the constantly developing technologies and nanotechnologies in
particular. Providing a presentation of practical applications of
the effects used in quantum metrology for the construction of
quantum standards and sensitive electronic components, the book is
useful for a wide audience of physicists and metrologists in
the broad sense of both terms. In 2014 a new system of units, the
so called Quantum SI, is introduced. This book helps to understand
and approve the new system to both technology and academic
community.
Chemical reactions and growth processes on surfaces depend on the
diffusion and re-orientation of the adsorbate molecules. A
fundamental understanding of the forces guiding surface motion is
thus of utmost importance for the advancement of many fields of
science and technology. To date, our understanding of the
principles underlying surface dynamics remains extremely limited,
due to the difficulties involved in measuring these processes
experimentally. The helium-3 spin-echo (HeSE) technique is uniquely
capable of probing such surface dynamical phenomena. The present
thesis extends the field of application of HeSE from atomic and
small molecular systems to more complex systems. Improvements to
the supersonic helium beam source, a key component of the
spectrometer, as well as a detailed investigation of a range of
five-membered aromatic adsorbate species are presented. The thesis
provides a comprehensive description of many aspects of the HeSE
method - instrumentation, measurement and data analysis - and as
such offers a valuable introduction for newcomers to the field.
This book is devoted to the analysis of measurement signals which
requires specific mathematical operations like Convolution,
Deconvolution, Laplace, Fourier, Hilbert, Wavelet or Z transform
which are all presented in the present book. The different problems
refer to the modulation of signals, filtration of disturbance as
well as to the orthogonal signals and their use in digital form for
the measurement of current, voltage, power and frequency are also
widely discussed. All the topics covered in this book are presented
in detail and illustrated by means of examples in MathCad and
LabVIEW. This book provides a useful source for researchers,
scientists and engineers who in their daily work are required to
deal with problems of measurement and signal processing and can
also be helpful to undergraduate students of electrical
engineering.
This book focuses on the state of the art in worldwide research on
applying optimization approaches to intelligently control charging
and discharging of batteries of Plug-in Electric Vehicles (PEVs) in
smart grids. Network constraints, cost considerations, the number
and penetration level of PEVs, utilization of PEVs by their owners,
ancillary services, load forecasting, risk analysis, etc. are all
different criteria considered by the researchers in developing
mathematical based equations which represent the presence of PEVs
in electric networks. Different objective functions can be defined
and different optimization methods can be utilized to coordinate
the performance of PEVs in smart grids. This book will be an
excellent resource for anyone interested in grasping the current
state of applying different optimization techniques and approaches
that can manage the presence of PEVs in smart grids.
In this book the applicability and the utility of two statistical
approaches for understanding dark energy and dark matter with
gravitational lensing measurement are introduced. For cosmological
constraints on the nature of dark energy, morphological statistics
called Minkowski functionals (MFs) to extract the non-Gaussian
information of gravitational lensing are studied. Measuring lensing
MFs from the Canada-France-Hawaii Telescope Lensing survey
(CFHTLenS), the author clearly shows that MFs can be powerful
statistics beyond the conventional approach with the two-point
correlation function. Combined with the two-point correlation
function, MFs can constrain the equation of state of dark energy
with a precision level of approximately 3-4 % in upcoming surveys
with sky coverage of 20,000 square degrees. On the topic of dark
matter, the author studied the cross-correlation of gravitational
lensing and the extragalactic gamma-ray background (EGB). Dark
matter annihilation is among the potential contributors to the EGB.
The cross-correlation is a powerful probe of signatures of dark
matter annihilation, because both cosmic shear and gamma-ray
emission originate directly from the same dark matter distribution
in the universe. The first measurement of the cross-correlation
using a real data set obtained from CFHTLenS and the Fermi Large
Area Telescope was performed. Comparing the result with theoretical
predictions, an independent constraint was placed on dark matter
annihilation. Future lensing surveys will be useful to constrain on
the canonical value of annihilation cross section for a wide range
of mass of dark matter annihilation. Future lensing surveys will be
useful to constrain on the canonical value of annihilation cross
section for a wide range of mass of dark matter.
This book is based on the author's work in the T2K long-baseline
neutrino oscillation experiment, in which neutrinos are generated
by a proton beam and are detected by near and far neutrino
detectors. In order to achieve the precise measurement of the
neutrino oscillation, an accurate understanding of the neutrino
beam and the neutrino interaction is essential. Thus, the author
measured the neutrino beam properties and the neutrino interaction
cross sections using a near neutrino detector called INGRID and
promoted a better understanding of them. Then, the author performed
a neutrino oscillation analysis using the neutrino beam and
neutrino interaction models verified by the INGRID measurements. As
a result, some values of the neutrino CP phase are disfavored at
the 90% confidence level. If the measurement precision is further
improved, we may be able to discover the finite CP phase which
involves the CP violation. Thus, this result is an important step
towards the discovery of CP violation in the lepton sector, which
may be the key to understanding the origin of the matter-antimatter
asymmetry in the universe.
Housed by a 4 m diameter tunnel of 27 km circumference, with huge
underground labs and numerous surface facilities, and set up with a
precision of 0.1 mm per kilometer, the Large Electron-Positron
Collider (LEP) was not only the largest but also one of the most
sophisticated scientific research instruments ever created by Man.
Located at CERN, near Geneva, LEP was built during the years 1983 -
1989, was operational until 2000, and corroborated the standard
model of particle physics through continuous high precision
measurements. The Author, director-general of CERN during the
crucial period of the construction of LEP, recounts vividly the
convoluted decision-making and technical implementation processes -
the tunnel alone being a highly challenging geo- and civil
engineering project - and the subsequent extremely fruitful period
of scientific research. Finally he describes the difficult decision
to close down LEP, at a time when the discovery of the Higgs boson
seemed within reach. LEP was eventually dismantled in 2000,
enabling the tunnel to be reused for building the next generation
machine, the much more powerful Large Hadron Collider (LHC), an
upgrade then called LEP3 and foreseen from the beginning. It became
operational just as this account was being completed. Written by
the main protagonist responsible for making LEP a reality, this is
the definitive inside story of a remarkable machine and the many
thousands of scientists and engineers from around the world, whose
efforts contributed to the new knowledge it produced.
The book offers a thorough introduction to machine vision. It is
organized in two parts. The first part covers the image
acquisition, which is the crucial component of most automated
visual inspection systems. All important methods are described in
great detail and are presented with a reasoned structure. The
second part deals with the modeling and processing of image signals
and pays particular regard to methods, which are relevant for
automated visual inspection.
