Ofer Ben-Amots' solo piano works and song cycles
No full textThis thesis builds upon the author's previous bachelor's thesis and expands the mapping and analysis of the compositional oeuvre of Ofer Ben-Amots. Following a comprehensive examination of his choral and operatic works, the thesis focuses on solo piano compositions and song cycles with piano accompaniment. The author delves into interpretative challenges and explores specific musical techniques employed by the composer in his creative process. Furthermore, the thesis aims to raise awareness of Ofer Ben-Amots' work among the general public.

Jazz Diasporas: Race, Music, and Migration in Post-World War II ParisJazz Diaspora: Music and Globalisation
No full textThis review examines two recent monographs that explore the concept of "jazz diaspora/s": Rashida Braggs’s Jazz Diasporas: Race, Music, and Migration in Post-World War II Paris and Bruce Johnson’s Jazz Diaspora: Music and Globalisation. While both authors engage with the term, they use it in distinct and sometimes contradictory ways, especially in terms of its theoretical implications for jazz scholarship and its global significance. By highlighting their approaches to power and identity, this review clarifies how each author contributes to understanding jazz as both an African diasporic music and a global phenomeno
Ofer Ben-Amots' solo piano works and song cycles
No full textDiplomová práce navazuje na bakalářskou práci téže autorky a rozvíjí mapování a analýzu skladatelského díla Ofera Ben-Amotse. Po důkladném zpracování jeho sborové a operní tvorby se práce soustředí na sólové klavírní skladby a písňové cykly s klavírním doprovodem. Autorka se zaměřuje na interpretační výzvy a hledá specifické hudební prostředky, které skladatel při své tvorbě využívá. Práce si rovněž klade za cíl dostat dílo Ofera Ben-Amotse do širšího povědomí široké veřejnosti.

Ofer Grosbard, Babel: A Guide to the East–West Encounter
No full textIn the scientific community, the constructs of Individualism and Collectivism arouse particular interest, so that the amount of literature produced is large and diverse. Many authors contributed to the development of the construct both in terms of theoretical validity and on measurement techniques and tools. Ofer Grosbard's book Babel-A Guide to the East-West Encounter is an example of this trend. Starting from the proposal of new principles characterizing the two different paradigms of thought (Eastern-Collectivist, Western-Individualist), the author coined the term Thinking Vector which can be oriented externally or internally depending on the individual's mode of thinking. The author also proposes a questionnaire for measuring the Thinking Vector and suggestions for an optimal encounter between individuals with different paradigms of the mind. The book offers the opportunity to reflect on the explanatory significance of the constructs of Individualism and Collectivism on both a theoretical and methodological level
Correlation functions in T T ¯ -deformed Conformal Field Theories
No full textAbstract We study the correlation functions of local operators in unitary T T ¯ -deformed field theories, using their formulation in terms of Jackiw-Teitelboim gravity. The position of the operators is defined using the dynamical coordinates of this formalism. We focus on the two-point correlation function in momentum space, when the undeformed theory is a conformal field theory. In particular, we compute the large momentum behavior of the correlation functions, which manifests the non-locality of the T T ¯ -deformed theory. The correlation function has UV-divergences, which are regulated by a point-splitting regulator. Renormalizing the operators requires multiplicative factors depending on the momentum, unlike the behavior in local QFTs. The large momentum limit of the correlator, which is the main result of this paper, is proportional to q − q 2 π Λ , where q is the momentum and 1/|Λ| is the deformation parameter. Interestingly, the exponent here has a different sign from earlier results obtained by resummation of small q computations. The decay at large momentum implies that the operators behave non-locally at the scale set by the deformation parameter

Ultrastructural analysis of dendritic spine necks reveals a continuum of spine morphologies: Models
No full textDendritic spines are membranous protrusions, with a bulbous head connected to the dendrite by a thin neck, and receive essentially all excitatory inputs in most mammalian neurons. Spines have a wide variety of morphologies that likely have a significant effect on their biochemical and electrical properties. The question of whether spines belong to distinct morphological or functional subtypes or constitute a continuum is still open. To discern this, it is important to measure spine necks objectively. Recent advances in electron microscopy enable automatic reconstructions of 3D spines with nanometer precision. Analyzing ultrastructural reconstructions from mouse neocortical neurons with computer vision algorithms, we demonstrate that the vast majority of spines can be rigorously separated into head and neck components. Analysis of the head and neck morphologies reveals a continuous distribution of parameters. The spine neck diameter, but not the neck length, was correlated with the head volume. Spines with larger head volumes often had a spine apparatus and pairs of spines in a post-synaptic cell contacted by the same axon had similar head volumes. Our data are consistent with a lack of morphological categories of spines and indicate that the morphologies of the spine neck and head are independently regulated. These results have repercussions for our understanding of the function of dendritic spines in neuronal circuits
Surface effects in simulations of scanning electron microscopy images
No full textWe have investigated the contributions of surface effects to Monte Carlo simulations of top-down scanning electron microscopy (SEM) images. The elastic and inelastic scattering mechanisms in typical simulations assume that the electron is deep in the bulk of the material. In this work, we correct the inelastic model for surface effects. We use a model for infinite flat surfaces, and apply it to non-flat, but smooth, geometries. Though this is a simplification, it captures most qualitative differences to the bulk model, including coupling to surface plasmons. We find that this correction leads to an increased SE signal near a feature's sidewall in low-voltage critical dimension SEM (CD-SEM). The effect is strongest for low beam energies. Due to some of the assumptions in our model, we are unable to quantitatively predict the extent by which the signal from the sidewall is enhanced. The enhancement of signal from the sidewall may be large enough to cause the measured edge position to shift significantly.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.ImPhys/Charged Particle Optic
