Synergy between quantum computing and semiconductor technology
No full textAs part of the National Agenda for Quantum Technology, QuTech (TU Delft and TNO) has agreed to make quantum technology accessible to society and industry via its full-stack prototype: Quantum Inspire. This system includes two different types of programmable quantum chips: circuits made from superconducting materials (transmons), and circuits made from silicon-based materials that localize and control single-electron spins (spin qubits). Silicon-based spin qubits are a natural match to the semiconductor manufacturing community, and several industrial fabrication facilities are already producing spin-qubit chips. Here, we discuss our latest results in spin-qubit technology and highlight where the semiconducting community has opportunities to drive the field forward. Specifically, developments in the following areas would enable fabrication of more powerful spin-qubit based quantum computing devices: circuit design rules implementing cryogenic device physics models, high-fidelity gate patterning of low resistance or superconducting metals, gate-oxide defect mitigation in relevant materials, silicon-germanium heterostructure optimization, and accurate magnetic field generation from on-chip micromagnets.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.BUS/TNO STAF
Ad Hoc communication topology switching during disasters from altruistic to individualistic and Back
No full textDisaster communication has made immense progress in the last thirty years. At present, disaster research focuses on bottom-up approaches such as civilian inclusion in disaster response. With the advent of smartphones, citizen-based emergency communication has become possible. Present ad hoc communication technologies typically form a fully connected mesh network, which connects all phones that are within each other's transmission range. This facilitates low-latency direct communication between citizens, but it quickly drains the battery of phones. Alternative ad hoc communication networks form an adaptive energy-efficient network topology, that is most draining to batteries of phones that have a higher charge, while low-energy phones are spared from relaying messages, thereby preserving battery and thus maintaining their connection with the rescue communication network. Both of these approaches have their own advantages. Which one is best for communication needs depends on the context. This position paper discusses the possibility of a decision model as an approach to automatically switch between the two alternative ad hoc communication networks. This ensures that citizens in disasters can make use of the optimal communication system at all times.System EngineeringMulti Actor System

Challenges for scanning electron microscopy and inspection on the nanometer scale for non-IC application: and how to tackle them using computational techniques
No full textIn this paper key challenges posed on metrology by feature dimensions of 20nm and below are discussed. In detail, the need for software-based tools for SEM image acquisition and image analysis in environments where CD-SEMs are not available and/or not flexible enough to cover all inspection tasks is outlined. These environments include research at universities as well as industrial R and D environments focused on non-IC applications. The benefits of combining automated image acquisition and analysis with computational techniques to simulate image generation in a conventional analytical SEM with respect to the overall reliability, precision and speed of inspection will be demonstrated using real-life inspection tasks as demonstrators.ImPhys/Charged Particle Optic
Motivating the Interest in Danish Literature with Mobile Persuasive Learning
No full textThis paper analyses and discusses the potential of Mobile Persuasive Learning (MPL) in relation to learning scenarios that involve complex and interdisciplinary learning material. A specific example of MPL is presented, which has been developed with the intent to motivate the interest of the life and works of Danish author and playwright Kaj Munk. A Persuasive Learning Design (PLD) is tried in a specific learning scenario that aims to introduce the history of Kaj Munk to students in lower secondary education in Vester Hassing in Northern Jutland. The methodological background for the chosen scenario is described and evaluation activities are presented and discussed and it is argued that while the topic is possibly too complex for the particular age group of students chosen, evaluation feedback and researcher observations point towards a significant potential in further developing MPL-designs in a school context
Geistige Höhenflüge des Kindesalters: die Kinderhexen Salzburgs
No full textThe "Zauberer-Jackl-trials", which took place in the archbishopric of Salzburg from 1675 to 1690 belong to the few Early Modern mass witch trials with children as the accused: roughly two thirds of the accused were either children or young adults from the beggar stratum, and most of them were executed. The legal process was focused on finding a so-called "Zauberer Jackl", i.e Jackl the Sorcerer, an alleged archmagus reputed for having apprenticed the children to the devil. The fact that this person, who the contemporaries believed was Jakob Koller, son of a criminal beggar woman, was never captured by the authorities earned Jackl the Sorcerer mythical status in the Alpine region. On the basis of the well preserved protocols of the trial held both at the local archbishopric courts and at the Grand Aulic Court in Salzburg, the study analyzes the confessions of the child-witches with an aim of exploring the fantasies formulated in the interrogation context.
Theory-wise, the study deals with the evaluation of ego documents, considering the complexities of human memory and the trickiness of communication. The argumentation implies that the psychological fathoming of sorcery-related fantasies functions should be sought on three levels (the experienced / the theologically construed / the childly-adolescent imaginary). In this respect, the most recent results of several humanistic disciplines are used. Introducing the neuropsychological perspective the author examines both Early Modern autobiographies and modern scientific studies of habitual distortion of memory i.e. false memories. Phenomena typical of mass witch trials, such as cross contamination and mythomaniac tendencies are heavily emphasized, with the help of the few available works devoted to the problem of children as witnesses. The discussion about developmental psychology affinities for the missing parent i.e. the projections derived therefrom (most of which is to be recognized in the Sabbath reports evident in the Salzburg protocols) is supplemented by results from recent studies about the resilience of children and adolescents and about "adult development". The issue of fantasy creation is also examined from a wider philosophically-psychological perspective.
Part I contains analyses of forty cases of interrogatoria of individuals involved in this mass trial. The study attempts to present the course of the interrogatories in an "interactive" way. It is in the courtroom that the sorcery drama takes place and it is here that fantastic scenarios arise, only to be modelled according to the pragmatic necessities of the interrogatory questionnaires. The dialectic process taking place between the judges and the accused is in each individual case differently configured. The figures of Jackl and the Devil (two regular male protagonists of the confessions) tend to reconfirm, in the eyes of the court, the subversive potential of the heretically perceived beggar group of children. However, within this narrative which reconstitutes itself throughout the trial, the child-witches and -warlocks are not only passive participants. In their capacity of informants they are rather dominant, although not all of them make use of this possibility to the same extent. Individual cases are treated in their chronological order, ideally beginning with the first interrogatory held at a local court, up until the last hearing at the Grand Aulic Court in Salzburg.
In Part II the author examines a selection of the most frequent motives, not only the 'standard' topics of witchcraft (weather magic, maleficent spells etc) but also facettes specific to this particular trial (e.g. magical zapping of animals and humans out of nowhere, host desecration, scatological notions, sodomy, homosexuality and bestiality, manifestations of emblematic figures of Evil). The study attempts to make the most of the wealth of multiple and (from the point of the psychological truth) equally trustworthy scenarios with which the sources abound. These scenarios offer insight into circumstances from the personal life of the beggar children (e.g. sibling rivalry, tense relationship with the stepmother etc).The necessity of dealing with certain topoi warrants introduction of additional written and visual sources, such as curiosity literature, Early Modern literary renderings of bandits i. e. gang leaders, but also modern counterparts of similar (anti)heroic figures. Where needed, brief philological speculations are made, some of which assuming a psycholinguistic bent. The analysis goes as far as recognizing the historical subject as having a Jungian capacity to intuitively grasp deep-seated archetypal structures.Die Zauberer-Jackl-Prozesse, die im Erzbistum Salzburg von 1675 bis 1690 stattfanden, gehören zu den wenigen Massenkinderhexenprozessen der frühneuzeitlichen Geschichte. Ungefähr zwei Drittel der im Rahmen dieser mehrjährigen Hexenjagd angeklagten Personen waren Kinder bzw. Jugendliche aus der Vagantenschicht. Im Fokus des rechtlichen Verfahrens stand der sog. Zauberer Jackl, ein angeblicher ‚Erzmagus‘, der Bettelkinder für den Teufel rekrutiert haben soll. Die Tatsache, dass dieser Mann nie verhaftet wurde, trug zu seinem mythischen Status im Alpenland bei. Anhand der gut erhaltenen Protokolle zu den am Salzburger Hofgericht sowie auf Lokalgerichtsebene geführten Verhören analysiert der Autor die Aussagen der Kinderhexen, mit dem Ziel, die im Kontext der Verhöre entstandenen Phantasien näher zu untersuchen
Bier, Wissenschaft und Wirtschaft in Deutschland, 1800 1914. Ein Beitrag zur deutschen Industrialisierungsgeschichte. By Mikul s Teich. Vienna: B hlau-Verlag, 2000. Pp. 355.
No full textThe author concludes with a quotation from J. D. Bernal (Die soziale Funktion der Wissenschaft. Berlin: Akademie, 1986: 22) to the effect that this book will have served its purpose if it manages to demonstrate that there is a problem. This is indeed the case, partly as a result of the author s research, and partly as a result of his omissions. Mikul s Teich, Emeritus Fellow of Robinson College, Cambridge, tries to reconstruct the brewing industry s importance for the German Industrial Revolution, emphasizing the surprising fact that before 1914 the brewing industry ranked first, alongside machine construction, in terms of capital investment. And although there are some general histories of brewing, none of them treats the interdependence of demand, scientific research, and technological innovation.
The Use and Abuse of Part-Time and Temporary Faculty
No full textThis article analyzes the structural, financial, and ethical dimensions of employing part-time and temporary faculty in university theatre programs. Based on institutional experience, it identifies both the practical necessity and systemic inequities inherent in contingent staffing models. The discussion outlines the benefits of such arrangements—access to specialized expertise, curricular flexibility, and expanded production capacity—alongside their drawbacks, including low compensation, lack of benefits, administrative instability, and risks of exploitation. The author argues that part-time staffing, while often indispensable, must be managed through flexible budgeting, administrative support, and professional respect for adjunct personnel. Examples from departmental practice demonstrate how increased autonomy in fiscal and personnel decisions can transform adjunct employment from a liability into a productive partnership. The article concludes that contingent faculty appointments, though symptomatic of larger resource shortages, can enhance departmental vitality when guided by institutional flexibility, transparency, and a genuine professional commitment to inclusion and fairness
