Antenna Designs for 5G/IoT and Space Applications, 2nd Edition
This reprint intends to shed some light on recent advances in antenna design for these new emerging applications and identify further research areas in this exciting field of communications technologies. Considering the specificity of the operational environment, e.g., huge distance, moving support (satellite), huge temperature drift, small dimensions with respect to distance, etc., antennas are fundamental devices that allow us to maintain a constant interoperability between ground stations and satellites or different satellites. Their high gain, stable performances (in terms of temperature and time), and long lifecycle are some of the requirements that necessitate special attention with respect to standard designs. The chapters of this reprint discuss various aspects of the above-mentioned list, presenting the view of the authors. Some of the contributors work strictly in the field (space), so they have a very targeted view of these subjects, while others with a more academic background propose futuristic solutions. We hope that interested readers will find a fertile source of information that, combined with their interest/background, will allow them to efficiently exploit the combination of these two perspectives.
Innovative Solutions for Concrete Applications
The Special Issue "Innovative Solutions for Concrete Applications" presents recent developments in the field of concrete technology and its applications. The articles and state-of-the-art reviews highlight the key themes such as sustainability, performance, durability, cost, environmental impact, recycling, and construction waste management. It also explores emerging techniques and innovations, including alkali-activated concrete, bacterial concrete, crumb rubber concrete, foamed concrete, waste-based concrete composites, and the reuse of construction and demolition waste. Sustainable concrete alternatives, innovative materials, and improved recycling and mixing techniques offer significant opportunities to reduce the environmental impact of concrete. However, challenges related to cost, long-term durability, and the application of life cycle assessment and life cycle cost analysis still need to be addressed through ongoing research. Furthermore, technologies such as three-dimensional concrete printing present advanced opportunities for innovation in the construction industry.
Empire of AI
From a brilliant longtime AI insider with intimate access to the world of OpenAI and Sam Altman from the beginning, an eye-opening account of arguably the most fateful tech arms race in history, reshaping the planet in real time, from the cockpit of the company that is driving the frenzy When longtime AI expert Karen Hao first began covering OpenAI in 2019, she thought they were the good guys. Founded as a nonprofit with safety enshrined as its core mission, it was meant, its leader Sam Altman told us, to act as a check against more purely mercantile forces. What could go wrong? Over time, first for the MIT Technology Review, then the Wall Street Journal, and now for the Atlantic, Hao began to wrestle ever more deeply with that question. Increasingly, she realized that the core truth of this massively disruptive sector is that breakthrough success requires an almost unprecedented amount of proprietary resources: the "compute" power of scarce high-end chips and the processing capacity to compile and drive these massive large language model data sets, the sheer volume of data that needs to be amassed at scale, the humans on the ground "cleaning up" the data for sweatshop wages throughout the global South, and a truly alarming spike in the need for energy and water underlying everything. Somewhere near you, a server farm is being built. The truth is that we have entered a new and ominous age of empire: only a small handful of globally scaled companies can even enter the field of play of this great game. How would Sam Altman and OpenAI resist such Faustian temptations? Spoiler alert: they didn't. Armed with Microsoft's billions, OpenAI is setting a breakneck pace, chased by a small group of the most valuable companies in human history. All this time, Hao has maintained her deep sourcing within OpenAI and the industry, and so she was in intimate contact last year with the story that shocked the entire tech industry--Altman's sudden firing by the OpenAI board just as he seemed at the top of the world, and then the board's ignominious retreat and Altman's triumphant return. The true story of what happened, told here in full for the first time, is one of the great tales of corporate hubris and dysfunction for the highest of stakes. But this isn't just a tale of a single company and its team, however fascinating they are. The g forces pressing down on this crew are deforming the judgement of everyone else too--as such forces do. Naked power finds the ideology to cloak itself; no one thinks they're the bad guy. But in the meantime, as Hao also shows through intrepid reporting on the ground around the world, the enormous wheels of extraction at scale grind on. An astonishing eyewitness view from both up in the command capsule of the new economy and down on the darkling plain where the real suffering happens at impact, Empire of AI is the book we need to pierce the veil and bring the stakes into sharp focus.

New Energy Competencies - A Guide for HR Professionals in Renewable Energy
Decentralizing Knowledges
In recent decades, there has been a call for decentering knowledge in the social sciences and humanities, bringing to light perspectives from previously ignored or undervalued groups or areas of the world. Feminist epistemologies and postcolonial studies have led this trend. However, there has been less interest in the specific infrastructures and practices that make decentering possible. Drawing from science and technology studies, Decentralizing Knowledges explores how to bring about such change. Contributors explore the multiple practices of knowledge production and circulation that favor and nurture nonhegemonic standpoints in academic fields, disciplines, and institutions--what they call epistemic decentralizing. The contributors combine theoretical and philosophical inquiry with empirical and historical case studies in settings ranging from palliative care in Taiwan, the repatriation of archaeological remains to Peru, and an experimental research platform in Kenya to a center of interdisciplinary ethnography in Ecuador and duck hunting as a knowledge practice of many indigenous S獺mi people. Throughout, the contributors provide an overview of the complex processes required to challenge mainstream epistemology. Contributors: Linda Mart穩n Alcoff, El穩as Barticevic, Johan Henrik Buljo, Ronald Cancino, Cristina Flores, Kim Fortun, Sandra Harding, Line Aimee Kalak, Duygu Kasdogan, Wiebke Keim, Aalok Khandekar, Daniel Lee Kleinman, Wen-Hua Kuo, John Law, Les Levidow, Leandro Rodriguez Medina, Angela Okune, Liv ?stmo, Ari Sitas, Maka Suarez, Sharon Traweek, Hebe Vessuri

New Fuels and Advanced Combustion Modes for Innovative Internal Combustion Engines
Today, the need to reduce both greenhouse gas and pollutant emissions is a challenge for the entire energy sector. Efforts to address this challenge have led to both the introduction of new technologies and improvements to the most widely used traditional ones. Among the latter, internal combustion engines (ICEs) provide about 25% of the world power today. In particular, the entire transport sector is largely based on this technology. Transitioning from ICEs to combustion-less technologies poses significant technical and economic challenges, making it unlikely that ICEs will be phased out soon. Therefore, enhancing their sustainability is crucial. In this scenario, this Special Issue collects studies focused on the following topics: the use of new fuels for ICEs for both automotive and railway applications, testing of additives for ICEs fed with conventional fuels, and computational fluid dynamics (CFD) simulation applied to the analysis and design of ICE components.
