Various cosmological observations support not only cosmological inflation in the early universe, which is also known as exponential cosmic expansion, but also that the expansion of the late-time universe is accelerating. To explain this phenomenon, the existence of dark energy is proposed. In addition, according to the rotation curve of galaxies, the existence of dark matter, which does not shine, is also suggested. If primordial gravitational waves are detected in the future, the mechanism for realizing inflation can be revealed. Moreover, there exist two main candidates for dark matter. The first is a new particle, the existence of which is predicted in particle physics. The second is an astrophysical object which is not found by electromagnetic waves. Furthermore, there are two representative approaches to account for the accelerated expansion of the current universe. One is to assume the unknown dark energy in general relativity. The other is to extend the gravity theory to large scales. Investigation of the origins of inflation, dark matter, and dark energy is one of the most fundamental problems in modern physics and cosmology. The purpose of this book is to explore the physics and cosmology of inflation, dark matter, and dark energy.

Die Tiefenfiltration ist für all jene technischen Anwendungen ein klassisches Verfahren zur Abscheidung von Partikeln aus Fluiden, bei welchen die Partikeln nur in mäßiger Konzentration von einigen mg/m3 vorkommen oder der Druckverlust sehr gering sein soll (VDI 3677 Blatt 2). In dieser Arbeit werden Messmethoden und Modelle entwickelt, die zur zukünftigen Simulation der Filtrationskinetik von Faserfiltermedien benötigt werden.Zum einen ist es notwendig, a priori die lokale Packungsdichte in einer Filterprobe zu kennen, um spätere Simulationen und Experimente für dieselbe Probe überprüfen zu können. Dies wird mit der neu entwickelten und verifizierten Methode zur Bestimmung der lokalen Packungsdichte innerhalb einer Filterprobe, basierend auf der mit quantitativer MRI gemessenen Faserstruktur, nun möglich. Weiterhin wird die hierfür notwendige Auflösung bestimmt sowie der Einfluss der Anordnung der lokalen Packungsdichten als auch der Einfluss der Zellengröße auf die Vorhersage des Druckverlustes mittels des in der Filtertechnik üblichen Zellenmodells untersucht.Zum anderen ist ein detailliertes Verständnis der Mikrophänomene bei der Beladung einzelner Fasern notwendig, da sich die Filterperformance aufgrund der abgeschiedenen Partikeln ändert. Hierzu ist, wie die Literaturübersicht zeigt, noch wenig bekannt. Daher wurde das CFD Programm FLUENT durch User-Defined-Functions so erweitert, dass der Aufbau von Partikelstrukturen an einzelnen Fasern unter Berücksichtigung des Sperreffekts als auch des Einflusses der abgeschiedenen Partikeln auf die Strömung sowie durch Modellierung von Haften bzw. Abprallen erstmals wirklichkeitsnah durchgeführt werden kann. Es wird gezeigt, dass eine qualitativ gute Übereinstimmung der Partikelstruktur mit experimentellen Ergebnissen anderer Arbeiten erzielt wird. Die Möglichkeit der Simulation erlaubt es dann, gezielt den Einfluss der Partikelhaftung auf die Morphologie und mittleren Packungsdichte der Partikelstruktur sowie auf die Änderung von Abscheidegrad und Druckverlust mit zunehmender Anzahl abgeschiedener Partikeln zu untersuchen. In weiteren Simulationen wird für monodisperse Latex- und Kalksteinpartikeln bei kleineren Stokeszahlen ein vertieftes Verständnis der Filtrationskinetik an Einzelfasern gewonnen. In einem Ausblick wird abschließend die mögliche Anwendung der neuen Routinen zur Simulation des Clogging von Faserstrukturen aufgezeigt.

Dental health is often overlooked in the early stages of childhood, with many parents assuming that it’s not essential to worry about their child's teeth until they are older. However, the truth is that the foundation for lifelong oral health begins in the earliest years of a child’s life. Pediatric dentistry plays a crucial role in shaping these healthy habits and ensuring that kids develop a strong, happy smile for years to come.

As India advances toward energy-efficient, sustainable infrastructure, demand for high-quality LED lighting solutions is growing rapidly. Among the many lighting options available today, LED flood lights have become the preferred choice for outdoor illumination across residential, commercial, and industrial sectors.

The impacts of climate change on water resource management, as well as increasingly severe natural disasters over the last decades, have caught global attention. Reliable and accurate hydrological forecasts are essential for efficient water resource management and the mitigation of natural disasters. While the notorious nonlinear hydrological processes make accurate forecasts a very challenging task, it requires advanced techniques to build accurate forecast models and reliable management systems. One of the newest techniques for modeling complex systems is artificial intelligence (AI). AI can replicate the way humans learn and has great capability to efficiently extract crucial information from large amounts of data to solve complex problems. The fourteen research papers published in this Special Issue contribute significantly to the uncertainty assessment of operational hydrologic forecasting under changing environmental conditions and the promotion of water resources management by using the latest advanced techniques, such as AI techniques. The fourteen contributions across four major research areas: (1) machine learning approaches to hydrologic forecasting; (2) uncertainty analysis and assessment on hydrological modeling under changing environments; (3) AI techniques for optimizing multi-objective reservoir operation; (4) adaption strategies of extreme hydrological events for hazard mitigation. The papers published in this issue will not only advance water sciences but also help policymakers to achieve more sustainable and effective water resource management.
