Development Strategies and Biodiversity: Darwinian Fitness and Evolution in the Anthropocene (Fascinating Life Sciences)

by David Costantini Valeria Marasco

Development is a complex and highly dynamic process involving the cross talk among genes, maternal effects and environmental circumstances. Widespread evidence from plant to animal species show that variation in developmental conditions can modulate life history trajectories and influence key traits, such as growth, reproduction, and senescence. These effects are not limited to a single generation but can also be passed on future generations. This book aims to bring together studies of early life effects from the fields of evolutionary biology, global change biology, and biomedicine to synthesise and improve current knowledge of the mechanisms involved, and how variation in early life conditions translates into Darwinian fitness outcomes. Relying on examples of organisms’ responses to the ongoing and future environmental challenges of the Anthropocene, this book takes a novel approach to address the adaptive meaning of early life effects. The book has a broad scientific approach, targeting eco-evolutionary biologists, behavioural biologists, eco-physiologists, eco-toxicologists, as well as epidemiologists and biomedical scientists.

Development and Characterization of a Dispersion-Encoded Method for Low-Coherence Interferometry

by Christopher Taudt

This Open Access book discusses an extension to low-coherence interferometry by dispersion-encoding. The approach is theoretically designed and implemented for applications such as surface profilometry, polymeric cross-linking estimation and the determination of thin-film layer thicknesses. During a characterization, it was shown that an axial measurement range of 79.91 µm with an axial resolution of 0.1 nm is achievable. Simultaneously, profiles of up to 1.5 mm in length were obtained in a scan-free manner. This marked a significant improvement in relation to the state-of-the-art in terms of dynamic range. Also, the axial and lateral measurement range were decoupled partially while functional parameters such as surface roughness were estimated. The characterization of the degree of polymeric cross-linking was performed as a function of the refractive index. It was acquired in a spatially-resolved manner with a resolution of 3.36 x 10-5. This was achieved by the development of a novel mathematical analysis approach.

by Antonio Colmenar-Santos David Borge-Diez Pedro-Miguel Ortega-Cabezas

This book evaluates the contributions of the electronic control unit software of an electric vehicle on sustainability and society, such as the reduction of emissions during a product design and the improvements in the vehicle. A sustainable transport model is proposed, demonstrating its economic viability. By validating software in a more efficient way and adding new functionalities to the software to enhance driving efficiency, energy consumption can be significantly reduced. Therefore, software validation and development have a significant impact on sustainability. This book offers innovative validation solutions based on artificial intelligence techniques to reduce validation time and emissions. The impact of driving efficiency on sustainable transport models is studied in detail, making proposals to be considered in the current environmental policies under discussion within the European Union in order to improve the sustainability of transport models. Vehicles are becoming sophisticated electronic systems due to the fact that they are integrating a significant number of electronic control units. This trend will certainly continue in the year to come. Consequently, software validation techniques are a key element for car manufacturers in order to ensure the quality of the vehicle. This book contributes to these efforts.

Development of 15 Micron Cutoff Wavelength HgCdTe Detector Arrays for Astronomy (Springer Theses)

by Mario Cabrera

This thesis describes advances in the understanding of HgCdTe detectors. While long wave (15 μm) infrared detectors HgCdTe detectors have been developed for military use under high background irradiance, these arrays had not previously been developed for astronomical use where the background irradiance is a billion times smaller. The main pitfall in developing such arrays for astronomy is the pixel dark current which plagues long wave HgCdTe. The author details work on the success of shorter wavelength development at Teledyne Imaging Sensors, carefully modeling the dark current–reverse bias voltage curves of their 10 μm devices at a temperature of 30K, as well as the dark current–temperature curves at several reverse biases, including 250 mV. By projecting first to 13 and then 15 μm HgCdTe growth, values of fundamental properties of the material that would minimize tunneling dark currents were determined through careful modeling of the dark current-reverse bias voltage curves, as well as the dark current-temperature curves. This analysis was borne out in the 13 μm parts produced by Teledyne, and then further honed to produce the necessary parameters for the 15 μm growth. The resulting 13 μm arrays are being considered by a number of ground-based astronomy research groups.

Development of Antibody-Based Therapeutics

by Gadi G. Bornstein Scott L. Klakamp Mohammad A. Tabrizi

Translational strategies for development of antibody-based therapeutics should allow understanding of the relationship between the 'unit dose' and 'unit effect' with respect to both beneficial and deleterious effects from early stages of development. The flow of information from later to earlier stages of development should provide opportunities to facilitate selection of more effective novel and next-generation drug candidates. Selection and evaluation of relevant biomarkers in early preclinical development in "relevant" animal models should allow for identifying potential risks to humans and establishing safe First-In-Human (FIH) dosing strategies. Hence, integration of knowledge with respect to target antigen properties such as antigen distribution, expression profile, kinetic properties, target pharmacology, antigen isoforms and pharmacological redundancy in health and disease, as well as antibody design criteria, such as antibody isotype, affinity, PK/PD and safety is a critical necessity for the design of effective translational strategies. Additionally, these factors will further offer critical differentiating characteristics for next-generation antibodies, and novel technologies prove instrumental in generation of biosuperior antibody candidates for market entry. This book will examine many important considerations necessary for the design of effective translational strategies during the development of antibody-based therapeutics.

Development of Coherent Detector Technologies for Sub-Millimetre Wave Astronomy Observations

by Boon-Kok Tan

The thesis describes the development of receiver technologies for sub-millimetre astronomy instruments, focusing on high performance coherent cryogenic detectors operating close to the superconductor gap frequency. The mixer chip which comprises the SIS devices, fed by a unilateral finline and matching planar circuits was fabricated on 15 micron silicon substrate using the recently developed Silicon-On-Insulator (SOI) technology. This offered broadband IF and RF performance, with fully integrated on-chip planar circuits resulting in an easily reproducible mixer chip and a simple mixer block. An important consequence of this design is that it can be extended to the supra-THz region and making the fabrication of multi-pixel heterodyne arrays feasible. The extension of the operation of major telescopes such as ALMA, APEX and the GLT from single pixel to large format arrays is the subject of extensive research at present time since it will allow fast mapping combined with high resolution of the submillimetre sky. The technology described in this thesis makes a major contribution to this effort.

Development of Implantable Electronics as Novel Approaches to Obstructive Sleep Apnea (Springer Theses)

by Jungmin Seo

This book addresses novel methods to treat a very popular disease, obstructive sleep apnea, based on a knowledge of an electrical engineering. Two approaches are given in the book using an upper-airway stimulation based on the pathogenesis of an obstructive sleep apnea. Implantable electronics are devised to control the tongue and the soft palate considering that they are the major pharyngeal muscles contributing to the apnea. First, for tongue control, a cuff electrode was designed and fabricated to stimulate the hypoglossal nerve, which innervates to the tongue muscle. Rare-earth magnets were embedded in the cuff for easy and repeatable installation of the electrode. For soft palate control, a palatal implant system was firstly developed to contract the soft palate muscle by applying electrical stimuli. Comprised of an implant, an intra-oral device, and an external controller, the palatal implant system is fully powered and controlled by means of wireless communication. The approaches were demonstrated in both in vitro and in vivo assessments, in collaboration with department of Otorhinolaryngology, Seoul National University Bundang Hospital.

Development of In-Tether Carbon Chiral Center-Induced Helical Peptide: Methodology and Applications (Springer Theses)

by Kuan Hu

This book focuses on the development of stapled peptides, a novel molecular modality used to regulate aberrant intracellular protein–protein interactions (PPIs). The author designs and presents a novel helical peptide stabilization methodology by constructing a chiral cross-linker moiety, namely “chiral center induced peptide helicity (CIH)”. The book demonstrates that a precisely positioned carbon chiral center on tether can decisively determine the secondary structure of a peptide, and that the R-configured peptide is helical, while the S-configured peptide is non-helical. Further, it reports that helicity-enhanced R isomer peptides displayed significantly enhanced cell permeability and target binding affinity, as well as tumor inhibition efficiency, in comparison to S isomer peptides. The book will not only advance readers’ understanding of the basic principle of stapled peptides, but also accelerate the clinical transformation of stapled peptide drugs.

Development of Mirror-Image VHHs with Less Immunogenicity (Springer Theses)

by Keisuke Aoki

This book outlines the chemical synthesis of therapeutic targets and a screening process for unexplored mirror-image single-domain antibodies (D-VHH). This book first describes the chemical synthesis of model VHH and the characteristics of both enantiomeric VHHs, including binding activity, biodistribution and immunogenicity. Immunogenicity testing in mice demonstrated that administration of conventional L-VHH induced the generation of anti-drug antibodies while D-VHH-binding antibodies were not observed in D-VHH-immunized mice. Second, it is explained that the T7-phage-based mirror-image screening system was developed to identify D-VHH antibody fragments capable of binding to vascular endothelial growth factors. Additionally, this book details the chemical synthesis of full-length hepatitis B virus core protein and interleukin-6 for the application of exploring D-VHHs and other mirror-image molecules. Demonstrating that it is possible to develop a D-VHH that preferentially binds the native target protein and exhibits reduced immunogenicity, this book is useful for anyone interested in developing alternative biotherapeutics with reduced immunogenicity by combining chemical and biological approaches.

All of the results described here will help readers to develop new catalytic performance of nanoporous metals for organic reactions.

Development of New Radical Cascades and Multi-Component Reactions

by Marie-Helene Larraufie

In this dissertation, Marie-Hélène Larraufie develops original radical and pallado-catalyzed methodologies to enable the synthesis of several classes of bioactive nitrogen-containing heterocycles. New radical cascades employing the N-acylcyanamide moiety offer straightforward routes to quinazolinones and guanidines, as well as new insights into the mechanism of homolytic aromatic substitutions. In parallel, Larraufie expands the scope of visible light photoredox catalysis to the ring opening of epoxides and aziridines, thus providing new sustainable alternatives for the generation of radicals. Furthermore, in a collaborative effort with the Catellani group, the author investigates dual palladium/norbornene catalysis. First, she develops a C-amination coupling variant of the Catellani reaction with unprotected amines which provides an expeditious route to phenanthridines. Then, she examines the influence of the chelating effect on Pd(IV) intermediates reactivity with the help of experimental studies and DFT calculations. The work in this thesis has resulted in numerous publications in high impact journals. The clarity and depth of the experimental section will be useful for students and researchers working in this field.

Development of Novel Bioelectrochemical Membrane Separation Technologies for Wastewater Treatment and Resource Recovery (Springer Theses)

by Yunkun Wang

The most commonly used biological wastewater treatment technologies still have serious technical-economical and sustainability-related limitations, due to their high energy requirements, poor effluent quality, and lack of energy and resource recovery processes. In this thesis, novel electrochemical membrane bioreactors (EMBRs), which take advantage of membrane separation and bioelectrochemical techniques, are developed for wastewater treatment and the simultaneous recovery of energy and resources. Above all, this innovative system holds great promise for the efficient wastewater treatment and energy recovery. It can potentially recover net energy from wastewater while at the same time harvesting high-quality effluent. The book also provides a proof-of-concept study showing that electrochemical control might offer a promising in-situ means of suppressing membrane fouling. Lastly, by integrating electrodialysis into EMBRs, phosphate separation and recovery are achieved. Hence, these new EMBR techniques provide viable alternatives for sustainable wastewater treatment and resource recovery.
