description: Experimental results of E2 transition probabilities or B(E2) values for the known first 2$^{+}$ states in 447 even-even nuclei have been compiled and evaluated. The evaluation policies for the analysis of experimental data have been described and new results are discussed. The recommended B(E2) values have been compared with comprehensive shell model calculations for a selected set of nuclei, where such theoretical procedures are amenable. The present work was motivated by a rapid increase in the number of new B(E2) measurements for the first 2$^{+}$ states since the previous evaluation of such data by S. Raman {\it et al.} published in 2001. Future plans to investigate the systematics of B(E2)$\uparrow$ values, and intercomparison of different experimental techniques to obtain these data are outlined.

description: We employ a variational method, in the framework of the Thomas-Fermi approximation, to study the effect of the symmetry energy on the neutron skin thickness and the symmetry energy coefficients of various neutron rich nuclei. We concentrate our interest on $^{208}$Pb, $^{124}$Sn, $^{90}$Zr, and $^{48}$Ca, although the method can be applied in the totality of medium and heavy neutron rich nuclei. Our approach has the advantage that the isospin asymmetry function $α(r)$, which is the key quantity to calculate isovector properties of various nuclei, is directly related with the symmetry energy as a consequence of the variational principle. Moreover, the Coulomb interaction is included in a self-consistent way and its effects can be separated easily from the nucleon-nucleon interaction. We confirm, both qualitatively and quantitatively, the strong dependence of the symmetry energy on the various isovector properties for the relevant nuclei, using possible constraints between the slope and the value of the symmetry energy at the saturation density.

description: These are materials for my Master thesis research: "Automatic Detection and Attribution of Quotes". Abstract Quotations extraction and attribution are important practical tasks for the media, but most of the presented solutions are monolingual. In this work, I present a complex machine learning-based system for extraction and attribution of direct and indirect quotations, which is trained on English and tested on Czech and Russian data. Czech and Russian test datasets were manually annotated as part of this study. This system is compared against a rule-based baseline model. Baseline model demonstrates better precision in extraction of quotation elements, but low recall. The machine learning-based model is better overall in extracting separate elements of quotations and full quotations as well.

description: We review the current status of baryogenesis with emphasis on electroweak baryogenesis and leptogenesis. The first detailed studies were carried out for SU(5) GUT models where CP-violating decays of leptoquarks generate a baryon asymmetry. These GUT models were excluded by the discovery of B+L violating sphaleron processes at high temperatures. Yet a new possibility emerged, electroweak baryogenesis. Here sphaleron processes generate a baryon asymmetry during a strongly first-order phase transition. This mechanism has been studied in many extensions of the Standard Model. However, constraints from the LHC and from low-energy precision experiments exclude most of the known models, leaving composite Higgs models of electroweak symmetry breaking as an interesting possibility. Sphaleron processes are also the basis of leptogenesis, where CP-violating decays of heavy right-handed neutrinos generate a lepton asymmetry which is partially converted to a baryon asymmetry. This mechanism is closely related to the one of GUT baryogenesis, and simple estimates based on GUT models can explain the order of magnitude of the observed baryon-to-photon ratio. In the one-flavour approximation an upper bound on the light neutrino masses has been derived which is consistent with the cosmological upper bound on the sum of neutrino masses. For quasi-degenerate right-handed neutrinos the leptogenesis temperature can be lowered from the GUT scale down to the weak scale, and CP-violating oscillations of GeV sterile neutinos can also lead to successfull leptogenesis. Significant progress has been made in developing a full field theoretical description of thermal leptogenesis, which demonstrated that interactions with gauge bosons of the thermal plasma play a crucial role. Finally, we discuss recent ideas how the seesaw mechanism and B-L breaking at the GUT scale can be probed by gravitational waves.

description: We explore the possibility that the fundamental theory of nature does not contain any scale. This implies a renormalizable quantum gravity theory where the graviton kinetic term has 4 derivatives, and can be reinterpreted as gravity minus an anti-graviton. We compute the super-Planckian RGE of adimensional gravity coupled to a generic matter sector. The Planck scale and a flat space can arise dynamically at quantum level provided that a quartic scalar coupling and its $β$ function vanish at the Planck scale. This is how the Higgs boson behaves for $M_h\approx 125$ GeV at $M_t\approx 171$ GeV. Within agravity, inflation is a generic phenomenon: the slow-roll parameters are given by the $β$-functions of the theory, and are small if couplings are perturbative. The predictions $n_s\approx 0.967$ and $r\approx 0.13$ arise if the inflaton is identified with the Higgs of gravity. Furthermore, quadratically divergent corrections to the Higgs mass vanish: a small weak scale is natural and can be generated by agravity quantum corrections.

description: We study the type-I seesaw model with three right-handed neutrinos and Majorana masses below the pion mass. In this mass range, the model parameter space is not only strongly constrained by the requirement to explain the light neutrino masses, but also by experimental searches and cosmological considerations. In the existing literature, three disjoint regions of potentially viable parameter space have been identified. In one of them, all heavy neutrinos decay shortly before big bang nucleosynthesis. In the other two regions, one of the heavy neutrinos either decays between BBN and the CMB decoupling or is quasi-stable. We show that previously unaccounted constraints from photodisintegration of nuclei practically rule out all relevant decays that happen between BBN and the CMB decoupling. Quite remarkably, if all heavy neutrinos decay before BBN, the baryon asymmetry of the universe can be quite generically explained by low-scale leptogenesis, i.e. without further tuning in addition to what is needed to avoid experimental and cosmological constraints. This motivates searches for heavy neutrinos in pion decay experiments.

description: Die Digitalisierung in der Arbeitswelt 4.0 vereinfacht durch neue Technologien die Zusammenarbeit über Distanz. Dadurch und aufgrund der Effekte, die sich infolge der Covid-Pandemie ergeben haben, arbeiten Personen in der Schweiz vermehrt mobil-flexibel. Diese Flexibilität führt zu einer erhöhten physischen Distanz in Teams. Es stellt sich die Frage, wie Führung erfolgreich über die Distanz gestaltet werden kann und welche Auswirkungen die Distanz auf die Nähe und somit das Zusammengehörigkeitsgefühl in Teams hat. Um diese Fragen beantworten zu können, erstellten Welge & Bruggmann (2021) ein Entwicklungsmodell für Führung auf Distanz, anhand dessen analysiert werden kann, wie das Führungsverständnis auf Basis der sozialen Identität zu einem Verständnis mit Fokus auf die Distanz entwickelt werden kann. Das Entwicklungsmodell mit den Faktoren Kommunikation, Attraktive Aufgaben & Ziele, Vertrauensvorschuss, Individuelle Faktoren, Sozioorganisatorische Faktoren und soziale Identität wird in dieser Arbeit im mobil-flexiblen Kontext untersucht. Zusätzlich wird erhoben, wie physische Nähe die Zusammenarbeit und Führung in der Distanz ergänzen kann. Die Ergebnisse zeigen, dass die Faktoren des Entwicklungsmodells anders über die Distanz erlebt werden als vor Ort. Dies erfordert eine Anpassung in der Zusammenarbeit wie auch in der Führungsarbeit mit Fokus auf Distanz, wie es im Entwicklungsmodell propagiert wird. Teams mit grösserer Erfahrung in distanziertem Arbeiten empfinden den Einfluss der Distanz auf die im Team vorhandene soziale Identität als geringer.

description: We interpret the recent NANOGrav results in terms of a stochastic gravitational wave background from metastable cosmic strings. The observed amplitude of a stochastic signal can be translated into a range for the cosmic string tension and the mass of magnetic monopoles arising in theories of grand unification. In a sizable part of the parameter space, this interpretation predicts a large stochastic gravitational wave signal in the frequency band of ground-based interferometers, which can be probed in the very near future. We confront these results with predictions from successful inflation, leptogenesis and dark matter from the spontaneous breaking of a gauged B-L symmetry.
What works? A grounded theory investigation into the impact of non-psychology staff using Solution-Focused Brief Therapy following brief training

description: Purpose: Psychologists are becoming increasingly more expected to offer consultation to support staff to deliver more effective care in healthcare services. The aim of this systematic review was to explore any themes reported in the literature in greater depth in order to provide novel insights into the underlying mechanisms that contribute to effective consultation. Method: Six databases were searched using a Highly Sensitive Search Strategy (HSSS), identifying 15 qualitative studies, which were quality-assessed using an adapted version of the CASP checklist. A meta-ethnographic approach was taken when analysing the studies looking at the experience of consultation from the perspectives of multidisciplinary, non-psychology staff. This included nurses, support workers, medical doctors, social workers, occupational therapists and managerial staff. Across the studies, the number of participants ranged from 5-57 with 70% of them being female, and with an age ranging from 18-65. Results: Six themes were developed highlighting the key aspects that were important to consider for effective consultation. Staff stressed the importance for consultation to help contain their emotional needs, to understand and connect with their clients and to feel their preference for an expert or collaborative approach to be considered. Conclusion:Recommendations for future clinical psychologists included clarifying the goals of consultation to reduce anxiety, be more accessible and flexible and adapt their language to staff preference in order to facilitate trusting relationships and more effective consultation. Future research should explore staff need and benefit of consultation by comparing experiences across other services and approaches to consultation.

description: Let ${\mathfrak g}$ be a complex semisimple Lie algebra, and $Y_h({\mathfrak g})$, $U_q(L{\mathfrak g})$ the corresponding Yangian and quantum loop algebra, with deformation parameters related by $q=\exp(πi h)$. When $h$ is not a rational number, we constructed in arXiv:1310.7318 a faithful functor $Γ$ from the category of finite-dimensional representations of $Y_h ({\mathfrak g})$ to those of $U_q(L{\mathfrak g})$. The functor $Γ$ is governed by the additive difference equations defined by the commuting fields of the Yangian, and restricts to an equivalence on a subcategory of $Y_h({\mathfrak g})$ defined by choosing a branch of the logarithm. In this paper, we construct a tensor structure on $Γ$ and show that, if $|q|\neq 1$, it yields an equivalence of meromorphic braided tensor categories, when $Y_h({\mathfrak g})$ and $U_q(L{\mathfrak g})$ are endowed with the deformed Drinfeld coproducts and the commutative part of the universal $R$-matrix. This proves in particular the Kohno-Drinfeld theorem for the abelian $q$KZ equations defined by $Y_h({\mathfrak g})$. The tensor structure arises from the abelian $q$KZ equations defined by a appropriate regularisation of the commutative $R$-matrix of $Y_h({\mathfrak g})$.

description: Both electrical injection and detection of spin-polarized electrons are demonstrated in a single wafer all-semiconductor GaAs-based lateral spintronic device, employing p+-(Ga,Mn)As/n+-GaAs ferromagnetic Esaki diodes as spin aligning contacts. Spin-dependent phenomena, such as spin precession and spin-valve effect, are observed in nonlocal signal and the measurements reveal the unusual origin of the latter in the investigated devices. The conversion of spin-polarized holes into spin-polarized electrons via Esaki tunneling leaves its mark in a bias dependence of the spin-injection efficiency, which at maximum reaches the value of 50%.

description: Word embeddings resulting from neural language models have been shown to be successful for a large variety of NLP tasks. However, such architecture might be difficult to train and time-consuming. Instead, we propose to drastically simplify the word embeddings computation through a Hellinger PCA of the word co-occurence matrix. We compare those new word embeddings with some well-known embeddings on NER and movie review tasks and show that we can reach similar or even better performance. Although deep learning is not really necessary for generating good word embeddings, we show that it can provide an easy way to adapt embeddings to specific tasks.

description: In this paper, we propose a low-rank representation with symmetric constraint (LRRSC) method for robust subspace clustering. Given a collection of data points approximately drawn from multiple subspaces, the proposed technique can simultaneously recover the dimension and members of each subspace. LRRSC extends the original low-rank representation algorithm by integrating a symmetric constraint into the low-rankness property of high-dimensional data representation. The symmetric low-rank representation, which preserves the subspace structures of high-dimensional data, guarantees weight consistency for each pair of data points so that highly correlated data points of subspaces are represented together. Moreover, it can be efficiently calculated by solving a convex optimization problem. We provide a rigorous proof for minimizing the nuclear-norm regularized least square problem with a symmetric constraint. The affinity matrix for spectral clustering can be obtained by further exploiting the angular information of the principal directions of the symmetric low-rank representation. This is a critical step towards evaluating the memberships between data points. Experimental results on benchmark databases demonstrate the effectiveness and robustness of LRRSC compared with several state-of-the-art subspace clustering algorithms.

description: In this paper, we provide a simple framework for deriving one-shot achievable bounds for some problems in quantum information theory. Our framework is based on the joint convexity of the exponential of the collision relative entropy, and is a (partial) quantum generalization of the technique of Yassaee et al. (2013) from classical information theory. Based on this framework, we derive one-shot achievable bounds for the problems of communication over classical-quantum channels, quantum hypothesis testing, and classical data compression with quantum side information. We argue that our one-shot achievable bounds are strong enough to give the asymptotic achievable rates of these problems even up to the second order.

description: How can the concept of networks contribute to understanding the role of households in crises where ICT infrastructure fail? ICT infrastructures are large-scale techno-material networks crucial to modern human social organisation and living. They play a role in connecting individuals to households and individuals and households to their wider surroundings. Drawing on fieldwork from a recent crisis in Norway, this article uses actor-network theory (ANT) as an analytical lens. The aim is twofold; firstly to show the effect of an ICT infrastructure breakdown on the concerns of households as a socio-material network, and secondly to suggest how these networks reconnect and are stabilised at a household level through strategies where people mobilise actants such as cars and intact pieces of ICT to establish new temporal associations of actor-networks.

description: We treat uncertain linear programming problems by utilizing the notion of weighted analytic centers and notions from the area of multi-criteria decision making. After introducing our approach, we develop interactive cutting-plane algorithms for robust optimization, based on concave and quasi-concave utility functions. In addition to practical advantages, due to the flexibility of our approach, we are able to prove that under a theoretical framework due to Bertsimas and Sim [14], which establishes the existence of certain convex formulation of robust optimization problems, the robust optimal solutions generated by our algorithms are at least as desirable to the decision maker as any solution generated by many other robust optimization algorithms in the theoretical framework. We present some probabilistic bounds for feasibility of robust solutions and evaluate our approach by means of computational experiments.

The longitudinal resistance of the 2DEG displays, as a function of the externally applied field, the long-predicted magnetic commensurability oscillations which result from the interplay between the two characteristic length scales of the system, the classical cyclotron radius Rc of the electrons and the period a of the magnetic field modulation.

description: In this paper, we explore how expertise is configured and enacted in consultancy work in public sector organizations. By drawing on recent writings on a sociology of expertise, we analyse expertise as a distributed performative actor-network effect. Through an empirical example from a process consultancy assignment in a hospital, we discern four modes of practice by which a network of expertise comes to work. Firstly, we explore a mode of extending a network of expertise to include more allies. Secondly, we observe a mode of activation where certain parts of the network are made active and present. Thirdly, we explore a mode of brokering between top management ambitions and the everyday medical practice. Fourthly, we see a mode of altering the content of the consultancy process to make it work with the client. Through this analysis, we move beyond viewing expertise as either an attribute to, or a substantial skill of the consultant and advance a heterogeneous social understanding of expertise in consultancy work.

description: The balance of cellular life and death is meticulously controlled in our bodies every day. However, perturbations in this balance can lead to pathological consequences and disease. I study a cell death pathway termed ferroptosis. Ferroptosis is implicated in many conditions, including Alzheimer’s. Pharmacological agents exist targeting ferroptosis, though their success is limited due to poor clinical performance. To study the potential of targeting this pathway in disease, my thesis perused new polymer nanotechnology platforms in which to anchor inhibitors of ferroptosis endowing them with superior pharmacological properties. I hope to advance the development of anti-ferroptosis nanomaterials and look to further validate their potential in future applications to complex disease pathology.

description: The energy spectrum of a two-dimensional electron system in a perpendicular homogeneous magnetic field and a weak lateral superlattice potential with square symmetry is composed of Landau bands with recursive internal subband structure. The Hall conductance in the minigaps is anticipated to be quantized in integer multiples of e2/h that vary erratically from minigap to minigap in accordance with a Diophantine equation. Hall measurements on samples with the requisite properties uncover this long searched for evidence of Hofstadter\'s butterflylike energy spectrum.

description: Recovering matrices from compressive and grossly corrupted observations is a fundamental problem in robust statistics, with rich applications in computer vision and machine learning. In theory, under certain conditions, this problem can be solved in polynomial time via a natural convex relaxation, known as Compressive Principal Component Pursuit (CPCP). However, all existing provable algorithms for CPCP suffer from superlinear per-iteration cost, which severely limits their applicability to large scale problems. In this paper, we propose provable, scalable and efficient methods to solve CPCP with (essentially) linear per-iteration cost. Our method combines classical ideas from Frank-Wolfe and proximal methods. In each iteration, we mainly exploit Frank-Wolfe to update the low-rank component with rank-one SVD and exploit the proximal step for the sparse term. Convergence results and implementation details are also discussed. We demonstrate the scalability of the proposed approach with promising numerical experiments on visual data.

description: The mode spectrum of micrometer-sized ferromagnetic Permalloy disks, exhibiting a vortex ground state, is investigated by means of time-resolved scanning Kerr microscopy. The temporal evolution of the magnetization is probed after application of a fast in-plane field pulse. The lowest order azimuthal mode, a mode with only one diametric node, splits into a doublet as the disk diameter decreases. Theoretical models show that this splitting is a consequence of the interaction of the mode with the gyrotropic motion of the vortex core. Our experiments and micromagnetic simulations confirm that by removing the vortex core from the disk, the mode splitting vanishes.
Social Reproduction and Political Change in The Wire
Creators: name: Jensen, Mikkel

description: This paper examines a core tension in the political television serial The Wire (2002-2008). While several critics have argued that this show is both “bleak” and “systemic” in its portrayal of contemporary society, this paper argues that it is useful to understand these textual elements as building blocks in The Wire’s attempt to create a coherent and consistent political argument. The paper argues that had The Wire been structured as a more uplifting and redeeming story, the systemic nature of its societal criticism would be undercut and the show would not embrace the logical consequence of the politics it espouses.

Networks as a case of distributed cognition
Creators: name: Allesøe, Bo
Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2017

description: Within the development of recent theories of epistemologies, notions of situated, embodied, extended and distributed cognition has been objects of study. Cognition is here seen as instantiated within different relationships, or networks, obtaining among humans and the world. However, what is shared by participating in a network is seldom addressed. This article will analyse and sketch the possibility of understanding a cognitive network, exemplified by a crime scene investigation, involving shared cognition understood as distributive ampliative cognition.

Tensions and co-existence
Creators: name: Stentoft, Diana
Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2016

description: This paper raises the issue of articulating intention as a means of positioning education and educational practices as useful and as offering a particular contribution to individuals and society. The paper explores the multifaceted articulations of intentions of problem-based learning, PBL, and the apparent co-existence of articulations of very diverse intentions despite potential tensions. The exploration identifies three distinct yet intertwined sets of intentions of PBL explicated in the articulations of PBL in current books and research papers. One, PBL as supporting the specific learning situation. Two, PBL as a pedagogy enabling students’ development of specific competencies. And three, PBL as a pedagogy ensuring the delivery of efficient and employable human resources who are competent to meet broader societal demands. These very different articulations of PBL currently co-exist without much debate, however scratching the surface reveals potential tensions. These tensions for example become apparent when posing the question ’for who do we do PBL’? Do we do it for the students in order to enrich him or her as individuals and give them a stake in their own education? Or do we do it for the state, the company or the organisation in order to deliver efficient and employable human resources?

The utility of psychiatric diagnosis

description: The validity of psychiatric diagnoses has been challenged because of a generally low validity of the existing diagnostic categories. However, it is important to distinguish between the validity and the utility of the psychiatric diagnostics. Although the validity of most contemporary psychiatric diagnoses is generally low and characterized by a low degree of natural boundaries, this does not mean that most psychiatric diagnoses are not useful concepts. The aim of this article is to focus on the utility of psychiatric diagnoses. This utility will be demonstrated with eating disorders as an example.

description: Im Artikel wurden Ergebnisse der simulativen Untersuchungen dargestellt, mit denen gemessen werden konnte, welchen Einfluss die fakultativen Direktzahlungen auf die durchschnittliche Höhe der Stützung je landwirtschaftlichen Betrieb in den einzelnen Woiwodschaften Polens hatten. Es wurde u.a. festgestellt, dass im Jahr 2017 infolge der Anwendung von freiwilligen Instrumenten die Änderung der durchschnittlichen Höhe der Stützung für landwirtschaftliche Betriebe in den Woiwodschaften, in denen diese Instrumente den stärksten Einfluss auf die zu untersuchende Variable ausübten, ca. +/-12 % betrug (im Vergleich zu der Situation, wenn die fakultativen Zahlungen nicht eingeführt würden und somit die für deren Finanzierung bestimmten Mittel im Rahmen der einheitlichen Flächenzahlung verteilt würden). Darüber hinaus wurde bemerkt, dass die in Polen angewandten fakultativen Instrumente zum Wachstum der durchschnittlichen Höhe der Stützung bei landwirtschaftlichen Betrieben in Mittel- sowie in Mittelostpolen, insbesondere in der Woiwodschaft Podlachien, beigetragen haben. In den westlichen, nördlichen und südlichen Woiwodschaften Polens wäre der durchschnittliche Betrag der Stützung pro landwirtschaftlichen Betrieb höher, wenn keine fakultativen Instrumente implementiert würden; somit wäre auch das Niveau der Finanzierung für die einheitliche Flächenzahlung höher.

description: We use the method of group contractions to relate wavelets analysis and Gabor analysis. Wavelets analysis is associated with unitary irreducible representations of the affine group while Gabor analysis is associated with unitary irreducible representations of the Heisenberg group. We obtain unitary irreducible representations of the Heisenberg group as contractions of representations of the extended affine group. Furthermore, we use these contractions to relate the two analyses, namely we contract coherent states, resolutions of the identity, and tight frames. In order to obtain the standard Gabor frame we construct a family of time localized wavelets frames that contract to that Gabor frame. Starting from a standard wavelets frame we construct a family of frequency localized wavelets frames that contract to a nonstandard Gabor frame. In particular we deform Gabor frames to wavelets frames.

description: Deciding which mall, hospital or school is closest to us is a problem we face everyday. It even comes on holidays with us, when we optimize our plans to make sure that we have enough time to visit all the attractions we want to see. In this article, we show how concepts from metric algebraic geometry help us to rise to this task while planning a weekend trip to the Black Forest.
