This book addresses the multiple technical aspects of the distribution of synchronization in new generation telecommunication networks, focusing in particular on synchronous Ethernet and IEEE1588 technologies. Many packet network engineers struggle with understanding the challenges that precise synchronization distribution can impose on networks. The usual “why”, “when” and particularly “how” can cause problems for many engineers. In parallel to this, some other markets have identical synchronization requirements, but with their own design requirements, generating further questions. This book attempts to respond to the different questions by providing background technical information. Invaluable information on state of-the-art packet network synchronization and timing architectures is provided, as well as an unbiased view on the synchronization technologies that have been internationally standardized over recent years, with the aim of providing the average reader (who is not skilled in the art) with a better understanding of this topic.

The book focuses specifically on synchronous Ethernet and IEEE 1588 PTP-based technologies, both key developments in the world of synchronization over the last 10 years. The authors address the needs of engineers and technical managers who are struggling with the subject of synchronization and provide an engineering reference for those that need to consider synchronization in NGN. The market applications that are driving the development of packet network synchronization and timing architectures are also discussed. This book provides a wide audience with everything they need to know when researching, implementing, buying and deploying packet synchronization architectures in telecommunication networks.

Divided into thirty-four chapters, this first-ever book on unilateral biportal endoscopic spine surgery presents the technique history review and its current applications; the currently available technology and basic principles of this surgery: anesthesia, position, and operative room setup; endoscopic instruments, hydrostatic pressure, and intraoperative radiology; as well as anatomical considerations of basic approaches. It also details the techniques to resolve lumbar, cervical and thoracic spine diseases.

Written by the world''s most influential groups that perform the method, Unilateral Biportal Endoscopy of the Spine: An Atlas of Surgical Techniqueswill certainly be widely accepted by all surgeons interested to improve their daily practice in minimally invasive spine surgery.

In April-May 1940 the German Wehrmacht invaded Northern and Western Europe. The subsequent occupation of Norway, Denmark, the Netherlands, Belgium, Luxembourg, and France brought the Jewish population of these countries – both established residents and refugees – under German control. From autumn 1941 in Luxembourg and from spring/summer 1942 in Belgium, the Netherlands and occupied France, Jews were required to wear the ‘Jewish star’ and many were subjected to forced labour. By mid-1942, deportations from Luxembourg and France to the ghettos and extermination camps in occupied Eastern Europe had already begun, while in the other occupied countries they were imminent. In April 1942 Alfred Oppenheimer, the Jewish elder in Luxembourg, wrote: ‘A dreadful fate hangs over our community again. The worst that can happen has now happened and the Poland transport is a certainty.’ This volume covers Norway and Western Europe during the period from the German invasion to mid 1942 (developments in Denmark for this period are documented in vol. 12) and records how Jews in these parts of Europe were excluded from society and stripped of their rights, livelihoods, and property. Letters and diary entries by the persecuted Jews detail life under German occupation and the attempts by many Jews to emigrate. The sources show how Jewish organizations sought to alleviate the impact of persecution, and how the German occupiers and local collaborators targeted Jews with increasingly stringent measures and clamped down on any form of resistance.

Die Lebenssituationen homosexueller Menschen in Deutschland und Europa wurden in der zweiten Hälfte des 20. Jahrhunderts von Widersprüchen geprägt: Während die staatliche Strafverfolgung weitgehend endete, erwiesen sich gesellschaftliche Diskriminierungen als deutlich langlebiger, bevor sie schließlich emanzipativen Entwicklungen Raum geben mussten. Ausgehend von den Nachwirkungen der NS-Homosexuellenverfolgung in den Nachkriegsgesellschaften der Bundesrepublik Deutschland, der DDR und Österreichs, betrachtet dieser Band die Vielfalt von Repressionen nach 1945. Die thematische Breite reicht von der Ausgrenzung innerhalb der Kommunistischen Partei über die Kriminalisierung homosexueller Handlungen im Strafrecht und antilesbische Ausrichtungen im Familienrecht bis hin zur homophoben Diskriminierung innerhalb der Bundeswehr. Untersucht werden auch die Rolle der Kirchen als Seismographen sexueller Ausgrenzung oder Liberalisierung sowie die emanzipativen Trends in den Transformationszeiten des späten 20. Jahrhunderts einschließlich ihrer Begrenzungen durch neue Formen mehrheitsgesellschaftlicher Anpassung und Normalisierung.

Im Mai 1940 überfiel die Deutsche Wehrmacht die Staaten Nord- und Westeuropas und besetzte sie weitgehend. Einheimische und die bis zu diesem Zeitpunkt nach Norwegen, in die Niederlande, nach Belgien, Luxemburg oder Frankreich geflüchteten Juden fielen jetzt unter deutsche Herrschaft. 1942 waren die Juden in allen Ländern Westeuropas zum Tragen des "Judensterns" verpflichtet, Zwangsarbeit war für Juden die Regel. In Frankreich und Luxemburg hatten die Deportationen in die Gettos und Vernichtungslager bereits begonnen, in den anderen Ländern standen sie unmittelbar bevor.

Dieser Band dokumentiert für die Zeit vom deutschen Einmarsch bis Mitte 1942 die schrittweise Entrechtung der Juden, ihre Isolation und die Zerstörung ihrer Existenzgrundlage mittels Berufsverboten und Enteignung. In Briefen und Tagebüchern schildern die verfolgten Juden das Leben unter deutscher Besatzung und die Versuche, diesem Leben durch Emigration doch noch zu entkommen. Die Dokumente zeigen, wie sich jüdische Organisationen bemühten, die Auswirkungen der Verfolgung zu mildern, und wie deutsche Machthaber aber auch einheimische Kollaborateure das Leben der Juden immer stärker reglementierten und jeden Widerstand zu ersticken suchten.

Auf der Basis der Edition realisiert der Bayerische Rundfunk die dokumentarische Höredition „Die Quellen sprechen“, die in Staffeln gesendet wird und unter www.die-quellen-sprechen.de nachzuhören ist.

Vom 9. bis zum 11. Mai 2023 fand mit "Der Holocaust als europäisches Ereignis" die Abschlusskonferenz der Edition "Die Verfolgung und Ermordung der europäischen Juden durch das nationalsozialistische Deutschland 1933–1945" im Dokumentationszentrum Topographie des Terrors in Berlin statt.

Intended for wire-bonding and flip-chip packaging professionals and for scientists and engineers working in the field of mechanical microsensors, this practical monograph introduces novel measurement technologies that allow for in situ and real-time examination of physical processes during the packaging process or during subsequent reliability tests. The measurement system presented here makes possible measurements at formerly inaccessible packaging interconnects. For the first time it becomes possible to describe the wire-bonding process window in terms of the physical forces at the contact zone instead of the applied machine settings. This is significant for a deeper understanding and future development of these packaging processes. Applications of the sensor in the field of wire bonding and flip-chip characterization are also illustrated. The reader will gain much insight into the important field of interconnection technology in semiconductor packaging.

Die Vermeidung arzneimittelbedingter Gesundheitsbeeinträchtigungen stellt eine Gemeinschaftsaufgabe aller am Arzneimittelverkehr beteiligten Personen und Institutionen dar. Kommt es durch bedenkliche Arzneimittel, infolge von Therapie- bzw. Indikationsfehlern, aufgrund fehlerhafter Arzneimittelanwendung oder im Rahmen der klinischen Arzneimittelprüfung zu Gesundheitsschäden, stellt sich daher die Frage, wer hierfür konkret zur Verantwortung zu ziehen ist. Dieser Frage geht der Autor aus strafrechtlicher Sicht nach, wobei neben der im Mittelpunkt stehenden Verantwortlichkeit des Arzneimittelproduzenten insbesondere auch die strafrechtliche Verantwortung des behandelnden Arztes, des das Arzneimittel an den Patienten abgebenden Apothekers sowie der den Arzneimittelverkehr bzw. die klinische Arzneimittelprüfung reglementierenden staatlichen Stellen untersucht wird.
