The author explains the technology that underpins the metaverse as it exists today and that will form the basis for its rapid evolution in the future. He also describes the commercial, ethical, and sociological implications of this technology, showing you the threats and opportunities that individuals and businesses are likely to encounter as they approach the metaverse for the first time. In the book, you'll discover: How the technology is shaping the human evolution and society How game mechanics and experience design are key to unlock the full potential of the Metaverse unlocking a new frontier for social interaction How Blockchain, digital currencies, and tokenomics are opening a new financial landscape for brands, creators and communities How Artificial intelligence and deep learning will shape the way businesses will conduct commerce in the Metaverse The ethical implications of designing highly emotionally impactful immersive experiences The potential dangers derived by the misuse of biometric and personal data to exploit consumer behaviour and for mass manipulation A thoroughly insightful discussion of a fascinating intersection of technology and humanity, Understanding the Metaverse belongs on the bookshelves of business leaders, technology enthusiasts, marketers, entrepreneurs, and anyone else with an interest in the next frontier of human achievement.

This brief addresses the design of model predictive control algorithms for performing space rendezvous manoeuvres. It consolidates developments within guidance and control algorithms, with the aim of improving the efficiency, safety, and autonomy of these manoeuvres. The brief presents several applications of model predictive control to rendezvous manoeuvres, including Ankersen zero-order-hold particular solution1, which provides a realistic thrust profile. It offers new approaches for rendezvous manoeuvres in elliptical orbits, formulating obstacle avoidance constraints, passive safety constraints, and robustness techniques. It also compares finite-horizon and variable-horizon formulations for model predictive control in the context of performance and computational complexity. Predictive Control for Spacecraft Rendezvous is accessible to academics and students new to the topics of orbital rendezvous and model predictive control, but also presents compelling subject matter for researchers and professionals in the aerospace industry.

When in the early 60s echography was introduced into the field of ophthalmol ogy, very few ophthalmologists realized the enormous potential of this procedure, the fundamental impact it would have on our branch of medicine or the innovations it would spawn. From its hesitant beginnings, echography has led to revolution in the field of ophthalmology and to our way of examining, treating and monitoring patients affected by eye disorders. This technique has brought untold benefits to patients worldwide. A crucial element in fostering the advance of the application of ultrasound in ophthalmology has been and is the biannual conference of the Societas Internationalis pro Diagnostica Ultrasonica in Ophthalmologia (SIDUO), and incidentally, the Latin name reflects the wish of the founding members that SIDUO be truly international, and even though the instruments and apparatus used in the discipline are highly innovative, the underlying philosophy is one that traces back to Hippocrates, i.e., the healing of man and the improvement of man's quality of life. The first SIDUO conference was held in 1964 in Berlin.

This study provides an updated analysis of the magnitude and frequency of peak stream discharges in Hawaii. Annual peak-discharge data collected by the U.S. Geological Survey during and before water year 2008 (ending September 30, 2008) at stream-gaging stations were analyzed. The existing generalized-skew value for the State of Hawaii was retained, although three methods were used to evaluate whether an update was needed. Regional regression equations were developed for peak discharges with 2-, 5-, 10-, 25-, 50-, 100-, and 500-year recurrence intervals for unregulated streams (those for which peak discharges are not affected to a large extent by upstream reservoirs, dams, diversions, or other structures) in areas with less than 20 percent combined medium- and high-intensity development on Kauai, Oahu, Molokai, Maui, and Hawaii. The generalized-least-squares (GLS) regression equations relate peak stream discharge to quantified basin characteristics (for example, drainage-basin area and mean annual rainfall) that were determined using geographic information system (GIS) methods. Each of the islands of Kauai, Oahu, Molokai, Maui, and Hawaii was divided into two regions, generally corresponding to a wet region and a dry region. Unique peak-discharge regression equations were developed for each region. The regression equations developed for this study have standard errors of prediction ranging from 16 to 620 percent. Standard errors of prediction are greatest for regression equations developed for leeward Molokai and southern Hawaii. In general, estimated 100-year peak discharges from this study are lower than those from previous studies, which may reflect the longer periods of record used in this study. Each regression equation is valid within the range of values of the explanatory variables used to develop the equation. The regression equations were developed using peak-discharge data from streams that are mainly unregulated, and they should not be used to estimate peak discharges in regulated streams. Use of a regression equation beyond its limits will produce peak-discharge estimates with unknown error and should therefore be avoided. Improved estimates of the magnitude and frequency of peak discharges in Hawaii will require continued operation of existing stream-gaging stations and operation of additional gaging stations for areas such as Molokai and Hawaii, where limited stream-gaging data are available.

El sistema de factores de crecimiento insulinico (IGF) es una familia de ligandos, receptores y proteinas que tienen un papel central en la regulacion de la proliferacion celular en el cancer de mama. La coexpresion de receptores a estrogeno (RE) y la cascada de senalizacion del factor de crecimiento insulinico tipo I (IGF-I) y su receptor (RIGF-I) en tumores mamarios humanos han conducido a la realizacion de estudios funcionales para la mejor comprension de la regulacion del crecimiento celular por estrogenos y por IGF-I. Se sabe que la activacion de ambas cascadas de senalizacion, la del RE y del IGF-I, esta implicada en la regulacion del crecimiento celular. La expresion y actividad del IGF-I son senaladas como potenciales blancos de drogas oncologicas y hasta como posibles marcadores pronosticos del cancer de mama y de otras neoplasias. Este trabajo explora los componentes de este sistema y las complejas interrelaciones que se establecen entre si y con las hormonas estrogenicas en un modelo experimental de cancer de mama en ratas diabeticas y no diabeticas."
