description: Frustrated quantum magnets are a central theme in condensed matter physics due to the richness of their phase diagrams. They support a panoply of phases including various ordered states and topological phases. Yet, this problem has defied a solution for a long time due to the lack of controlled approximations which make it difficult to distinguish between competing phases. Here we report the discovery of a special quantum macroscopically degenerate point in the XXZ model on the spin-1/2 kagome quantum antiferromagnet for the ratio of Ising to antiferromagnetic transverse coupling Jz/J=-1/2. This point is proximate to many competing phases explaining the source of the complexity of the phase diagram. We identify five phases near this point including both spin-liquid and broken-symmetry phases and give evidence that the kagome Heisenberg antiferromagnet is close to a transition between two phases.

description: We consider the following generalized derivative nonlinear Schrödinger equation \begin{equation*} i\partial_tu+\partial^2_xu+i|u|^{2σ}\partial_xu=0,\ (t,x)\in\mathbb R\times\mathbb R \end{equation*} when $σ\in(0,1)$. The equation has a two-parameter family of solitary waves $$u_{ω,c}(t,x)=Φ_{ω,c}(x)e^{iωt+\frac{ic}2x-\frac i{2σ+2}\int_0^xΦ_{ω,c}(y)^{2σ}dy},$$ with $(ω,c)$ satisfying $ω>c^2/4$, or $ω=c^2/4$ and $c>0$. The stability theory in the frequency region $ω>c^2/4$ was studied previously. In this paper, we prove the stability of the solitary wave solutions in the endpoint case $ω=c^2/4$ and $c>0$.

description: This paper introduces ΔBreakpad. It extends the Breakpad crash reporting system to handle software diversity effectively and efficiently by replicating and patching the debug information of diversified software versions. Simple adaptations to existing open source compiler tools are presented that on the one hand introduce significant amounts of diversification in the code and stack layout of ARMv7 binaries to mitigate the widespread deployment of code injection and code reuse attacks, while on the other hand still supporting accurate crash reporting. An evaluation on SPEC2006 benchmarks demonstrates that the corresponding computational, storage, and communication overheads are small.

Long-lasting Quantum Memories: Extending the Coherence Time of Superconducting Artificial Atoms in the Ultrastrong-Coupling Regime

description: Quantum systems are affected by interactions with their environments, causing decoherence through two processes: pure dephasing and energy relaxation. For quantum information processing it is important to increase the coherence time of Josephson qubits and other artificial two-level atoms. We show theoretically that if the coupling between these qubits and a cavity field is longitudinal and in the ultrastrong-coupling regime, the system is strongly protected against relaxation. Vice versa, if the coupling is transverse and in the ultrastrong-coupling regime, the system is protected against pure dephasing. Taking advantage of the relaxation suppression, we show that it is possible to enhance their coherence time and use these qubits as quantum memories. Indeed, to preserve the coherence from pure dephasing, we prove that it is possible to apply dynamical decoupling. We also use an auxiliary atomic level to store and retrieve quantum information.

description: Bright and ultrashort duration X-ray pulses can be produced by through betatron oscillations of electrons during Laser Wakefield Acceleration (LWFA). Our experimental measurements using the \textsc{Hercules} laser system demonstrate a dramatic increase in X-ray flux for interaction distances beyond the depletion/dephasing lengths, where the initial electron bunch injected into the first wake bucket catches up with the laser pulse front and the laser pulse depletes. A transition from an LWFA regime to a beam-driven plasma wakefield acceleration (PWFA) regime consequently occurs. The drive electron bunch is susceptible to the electron-hose instability and rapidly develops large amplitude oscillations in its tail, which leads to greatly enhanced X-ray radiation emission. We measure the X-ray flux as a function of acceleration length using a variable length gas cell. 3D particle-in-cell (PIC) simulations using a Monte Carlo synchrotron X-ray emission algorithm elucidate the time-dependent variations in the radiation emission processes.

description: Abstract Context: The Brazilian General Data Protection Law (LGPD) implementation has impacted activities carried out by the software development teams. Due to it, developers had to become aware of the existing techniques and tools to carry out privacy requirements elicitation. Objectives: Extending our previous work, we have investigated the actions taken by organizations regarding the LGPD, specifically in software development, considering the perception of agile development teams after two years of the LGPD implementation. In addition, we also investigated the perception of an agile team regarding the practices, techniques, and tools previously cited by practitioners as potential solutions for use in this context, along with techniques already in use in the current context. Methods: We have conducted a systematic literature review (SLR) and selected 36 primary studies. Furthermore, we have conducted a survey with 53 IT practitioners and semi-structured interviews with ten practitioners. Results: The LGPD principles are known by most agile teams and are being implemented by the organizations, although the existing tools to support privacy requirements elicitation are still underused by agile teams. Moreover, agile teams consider that software requirements and software construction are the most impacted areas of knowledge by the LGPD, and most of them use user stories in privacy requirements elicitation. Conclusions: Our findings reveal that agile teams and Brazilian organizations are more concerned with user data privacy issues after the LGPD became effective. However, agile teams still face challenges in privacy requirements elicitation.

Creators: name: Hutton, Steven
Publisher: name: Lancaster University
Year: 2023

description: This thesis examines how open innovation is related to dynamic capabilities and strategic agility using an empirical approach. By adopting a microfoundations lens and examining open innovation processes, first, I develop a model to explain how open innovation is related to sensing and seizing abilities of the dynamic capability framework. Next, by considering resource bundling and individuals’ activities alongside broader organisational conditions and activities, I develop a framework to further explain the relationship between open innovation and a firm’s dynamic capability. Finally, to address the omission of speed from the dynamic capability literature and the development of resources and capabilities, I develop a framework to explain the interplay between open innovation and a firm’s strategic agility. In doing so, this thesis advances our understanding of the open innovation concept by linking open innovation to strategic firm-level concepts. Furthermore, this thesis contributes to our understanding of the multi-level nature of open innovation by uncovering microfoundations that underlie the relationship between open innovation and strategic firm-level concepts.

description: We consider continuous-time Markov chains which display a family of wells at the same depth. We provide sufficient conditions which entail the convergence of the finite-dimensional distributions of the order parameter to the ones of a finite state Markov chain. We also show that the state of the process can be represented as a time-dependent convex combination of metastable states, each of which is supported on one well.

description: It is essential to tell some other reasons why you should tell that you need assistance with that particular task. But hey, it is mostly not that simple. Getting an acceptance speech can be hectic if you barely have a topic in mind. Besides, even though numerous applicants are egotistic, yet they all seem to be seeking the same chance, there is always a reason for them to ignore each other https://topswriting.com/review/papernow. So if they do not convince you that their application is worth the try, let's look at the bright side of the coin, and see what that could be.

Let an Expert in that Relevant Job Introductory Line Understand Your Customer

Your personal information, interests, and achievements will indeed be included in the essay. However, how well you write that paper is contingent on the kind of person that you are. Hence, you ought to consistently ensure that the very first thing that the admissions board sees is someone who is not only capable of providing genuine and valuable service, but also a great provider of applications. This is also another quality that you are looking for.

Solace the Fluency of the School

Most schools nowadays utilize an online automated software that categorizes students based on the ability to submit several customized forms. Once the form is generated, the managers will crosscheck the data and, as a result, will promptly separate those that have more academic and skills from others. Another critical factor to consider before sending the application is whether the school's website has been optimized. It will achieve this by having a highly informative accept and rejection rate. This will then give the applicant an advantage, which is usually the best option for a student.

Prepare for the Test Presentation

This is precisely the point where most teachers send an Admission Letter. If yours is not well-formatted, it might end up rejected by the panel, forcing the student to seek explanation, and hence it won't go through. The committee is charged with the responsibility of ensuring that the brilliant candidate goes on to the test. Having a perfect test presentation will, in fact, aid the processor of that individual quickly to make changes, recognizing these efforts are often the fastest. Remember, since the Login feature is on the app, it cannot be disabled. Thus, to present a top-notch display, the student has to break down the activity into small, manageable pieces that are easy to understand and follow.

Quantum Multicriticality near the Dirac-Semimetal to Band-Insulator Critical Point in Two Dimensions: A Controlled Ascent from One Dimension

description: We compute the effects of generic short-range interactions on gapless electrons residing at the quantum critical point separating a two-dimensional Dirac semimetal (DSM) and a symmetry-preserving band insulator (BI). The electronic dispersion at this critical point is anisotropic ($E_{\mathbf k}=\pm \sqrt{v^2 k^2_x + b^2 k^{2n}_y}$ with $n=2$), which results in unconventional scaling of physical observables. Due to the vanishing density of states ($\varrho(E) \sim |E|^{1/n}$), this anisotropic semimetal (ASM) is stable against weak short-range interactions. However, for stronger interactions the direct DSM-BI transition can either $(i)$ become a first-order transition, or $(ii)$ get avoided by an intervening broken-symmetry phase (BSP). We perform a renormalization group analysis by perturbing away from the one-dimensional limit with the small parameter $ε= 1/n$, augmented with a $1/n$ expansion (parametrically suppressing quantum fluctuations in higher dimension). We identify charge density wave (CDW), antiferromagnet (AFM) and singlet s-wave superconductor as the three dominant candidates for the BSP. The onset of any such order at strong coupling $(\sim ε)$ takes place through a continuous quantum phase transition across multicritical point. We also present the phase diagram of an extended Hubbard model for the ASM, obtained via the controlled deformation of its counterpart in one dimension. The latter displays spin-charge separation and instabilities to CDW, spin density wave, and Luther-Emery liquid phases at arbitrarily weak coupling. The spin density wave and Luther-Emery liquid phases deform into pseudospin SU(2)-symmetric quantum critical points separating the ASM from the AFM and superconducting orders, respectively. Our results can be germane for a uniaxially strained honeycomb lattice or organic compound $α$-(BEDT-TTF)$_2\text{I}_3$.

description: Onion (Allium cepa L.) is an economically important vegetable crop worldwide. However, various fungal diseases, including Fusarium basal rot (FBR), neck rot, and white rot, reduce onion production or bulb storage life. FBR caused by Fusarium species is among the most destructive onion diseases. In this study, we identified Fusarium species associated with FBR in Jeolla and Gyeongsang Provinces in South Korea and evaluated fungicides against the pathogens. Our morphological and molecular analyses showed that FBR in onions is associated with Fusarium commune, Fusarium oxysporum, and Fusarium proliferatum. We selected seven fungicides (fludioxonil, hexaconazole, mandestrobin, penthiopyrad, prochloraz-manganese, pydiflumetofen, and tebuconazole) and evaluated their inhibitory effects on mycelial growth of the pathogens at three different concentrations (0.01, 0.1, and 1 mg/mL). We found that prochloraz-manganese was highly effective, inhibiting 100% of the mycelial growth of the pathogens at all concentrations, followed by tebuconazole. Fludioxonil showed < 50% inhibition at 1 mg/mL for the tested isolates.
title: An assessment of breast cancer cell invasion into the bone marrow
Creators: name: Laverty, Thomas
Publisher: name: University of Glasgow
Year: 2023

description: Breast cancer is the most commonly diagnosed cancer in women. With the largest clinical problem coming in the form of metastasis. Breast cancer is known to metastasise to secondary tumour sites within the body, namely the liver, brain, lungs and bone marrow. Upon colonisation of the bone marrow, disseminated breast cancer cells (DBCC) interact with resident bone marrow niche cells such as mesenchymal stem cells (MSCs). These interactions are partly responsible for the phenomenon of dormancy observed in DBCCs. In time DBCCs can reawaken, resulting in recurrence and aggressive secondary metastasis, with a very poor clinical outcome for patients. In order for further investigation into this phenomenon, an in vitro dormant breast cancer cell model was developed using the breast cancer cell line MCF7. This model was then used to investigate the triggers of dormant breast cancer cell reawakening. A hallmark of cancer is an altered metabolic profile, as such the model described above was utilised in order to investigate the influence of secreted factors likely present within the bone marrow niche, on the behaviour of dormant breast cancer cells. Conditioned media from both adipogenic and osteogenic lineage MSCs was shown to be capable of triggering proliferation in the dormant breast cancer cell model. Investigation into the contents of the secretome revealed several pathways shown to be upregulated. These pathways may have an effect on the reawakening of the dormant breast cancer cells. The most interesting pathways revealed by this analysis were the arginine and proline metabolism pathway along with citrulline metabolism, with both providing interesting avenues of exploration. In this thesis a dormant breast cancer cell model is described and utilised in order to investigate potential triggers of reactivation. Using this model to screen various potential activators of the dormant cancer, the secretome of both adipogenic and osteogenic lineage MSCs was shown to cause an upregulation in the proliferation of dormant MCF7 cells. Specific metabolites of interest were identified such as ornithine, an intermediary molecule in the urea cycle, capable of generating arginine necessary for cellular proliferation. This model thus, can be used for future experiments in order to further investigate the causes behind breast cancer cell dormancy and reawakening.

title: An investigation of professional communities amongst those responsible for English teacher development in Oman
Creators: name: Al-Sinani, Salima Khamis
Publisher: name: University of Glasgow
Year: 2023

description: Research into professional communities has grown internationally over the past three decades. Although there are a range of definitions, most agree professional communities provide an environment for professionals, including educators, to share knowledge, problem-solving and professional values, while developing networks. This research sheds light on two kinds of identified professional communities: ‗Communities of Practice‘ (CoPs), and ‗Professional Learning Communities‘ (PLCs). The latter was recently adopted in the Omani educational context, as a model for improving the achievements of schools and students. This study investigated the collaborative work (or lack of it) of English-subject teacher-educators acting as trainers, supervisors, and senior school teachers – roles which were created after educational reforms in 1998/1999. There is scant research regarding how these groups operate together as teacher-educators supporting school teachers. Embracing an interpretive approach over fieldwork totalling 6 months, I investigated the perceptions of 8 trainers, 12 supervisors and 11 senior teachers across three governorates in Oman and 5 senior staff from the Ministry of Education (MoE)‘s Supervision and Training departments. I used semi-structured interviews, an in-depth analysis of national policies, and non-participant observation of group meetings for data triangulation. The study highlighted seven key findings. The most salient revealed mixed attitudes in participants‘ perceptions regarding their collegial workplace-relationships and collaborations. A number of participants highlighted the passive role played by their MoE leadership in terms of enhancing better relationships and communication between them. The findings also revealed an overlap in the roles and responsibilities of trainers and supervisors, which causes conflict between these two groups in some governorates. Finally, obstacles such as negative attitudes, differing cultural behaviours, an overwhelming workload and the extensive range of duties demanded were all highlighted as challenges that would hinder the implementation of professional communities. The study recommends that MoE officials consider addressing these obstacles to implement professional communities effectively in the future and calls for more collaboration between the three groups to enhance their working relations. The study extends our understanding of how Western ‗professional communities‘ principles work when adapted for use in the Omani context.
title: Changing children's intergroup attitudes towards stigmatised groups : testing theoretically derived prejudice-reduction interventions
Creators: name: Cameron, Lindsey
Publisher: name: University of Kent
Year: 2022

description: The aim of this thesis was to design and evaluate theoretically derived prejudice- reduction interventions for children (5 to 11 years) as a means of obtaining more effective prejudice-reduction interventions and advancing psychological theories of prejudice. In the thesis, the potential contribution of psychology to the intervention literature in terms of theoretical models and methodological issues is discussed and its contribution to the intervention literature to date is analysed. The interventions tested are multiple classification skills training and a number of versions of extended contact, which were derived from different models of inter-group contact. Interventions were evaluated using measures of out- and in-group attitude, intended behaviour, affect and implicit bias. Throughout the thesis it is hypothesised that, following the interventions, children will hold more favourable out-group attitudes. It is predicted that, of the extended contact models, the ‘inter-group’ and ‘dual identity’ versions will be the most effective. It is also hypothesised that the extended contact effect will be mediated by ‘inclusion of other in the self and perceived norms, and will be moderated by age and identity. It is expected that implicit bias will be reduced following interventions, but only in the older age group. The results of four experimental studies are presented and the hypotheses are considered in each chapter. In summary, the findings show strong support for the use of extended contact, especially ‘dual identity’ and ‘inter-group’ extended contact, as a prejudice reduction tool in children aged 5 to 11 years. There is little support for the multiple-classification skills training intervention. Results indicate that extended contact is mediated by ‘inclusion of other in the self and is moderated by in-group identity. Perceived in-group norm does not appear to be a mediator of extended contact. The theoretical and practical implications of these findings are discussed. It is concluded that by incorporating psychological theories into prejudice-reduction interventions, and by considering psychological issues in the implementation and evaluation of these interventions, this can lead to effective prejudice-reduction tools and also advance psychological theories of prejudice.
A locally supersymmetric $SO(10,2)$ invariant action for $D=12$ supergravity

description: We present an action for $N=1$ supergravity in $10+2$ dimensions, containing the gauge fields of the $OSp(1|64)$ superalgebra, i.e. one-forms $B^{(n)}$ with $n$=1,2,5,6,9,10 antisymmetric D=12 Lorentz indices and a Majorana gravitino $ψ$. The vielbein and spin connection correspond to $B^{(1)}$ and $B^{(2)}$ respectively. The action is not gauge invariant under the full $OSp(1|64)$ superalgebra, but only under a subalgebra ${\tilde F}$ (containing the $F$ algebra $OSp(1|32)$), whose gauge fields are $B^{(2)}$, $B^{(6)}$, $B^{(10)}$ and the Weyl projected Majorana gravitino ${1 \over 2} (1+Γ_{13}) ψ$. Supersymmetry transformations are therefore generated by a Majorana-Weyl supercharge and, being part of a gauge superalgebra, close off-shell. The action is simply $\int STr ({\bf R}^6 {\bf Γ})$ where ${\bf R}$ is the $OSp(1|64)$ curvature supermatrix two-form, and ${\bf Γ}$ is a constant supermatrix involving $Γ_{13}$ and breaking $OSp(1|64)$ to its ${\tilde F}$ subalgebra. The action includes the usual Einstein-Hilbert term.

description: Demand response (DR) programs have emerged as a potential key enabling ingredient in the context of smart grid (SG). Nevertheless, the rising concerns over privacy issues raised by customers subscribed to these programs constitute a major threat towards their effective deployment and utilization. This has driven extensive research to resolve the hindrance confronted, resulting in a number of methods being proposed for preserving customers' privacy. While these methods provide stringent privacy guarantees, only limited attention has been paid to their computational efficiency and performance quality. Under the paradigm of differential privacy, this paper initiates a systematic empirical study on quantifying the trade-off between privacy and optimality in centralized DR systems for maximizing cumulative customer utility. Aiming to elucidate the factors governing this trade-off, we analyze the cost of privacy in terms of the effect incurred on the objective value of the DR optimization problem when applying the employed privacy-preserving strategy based on Laplace mechanism. The theoretical results derived from the analysis are complemented with empirical findings, corroborated extensively by simulations on a 4-bus MG system with up to thousands of customers. By evaluating the impact of privacy, this pilot study serves DR practitioners when considering the social and economic implications of deploying privacy-preserving DR programs in practice. Moreover, it stimulates further research on exploring more efficient approaches with bounded performance guarantees for optimizing energy procurement of MGs without infringing the privacy of customers on demand side.

As a corollary, we prove an analog of Boutot's theorem that direct summands of regular rings are pseudo-rational in mixed characteristic. Our proof uses perfectoid spaces and is inspired by the recent breakthroughs on the direct summand conjecture by André and Bhatt.

description: We study stochastic dynamics of a point and extended inclusion within a one dimensional confined active viscoelastic gel. We show that the dynamics of a point inclusion can be described by a Langevin equation with a confining potential and multiplicative noise. Using a systematic adiabatic elimination over the fast variables, we arrive at an overdamped equation with a proper definition of the multiplicative noise. To highlight various features and to appeal to different biological contexts, we treat the inclusion in turn as a rigid extended element, an elastic element and a viscoelastic (Kelvin-Voigt) element. The dynamics for the shape and position of the extended inclusion can be described by coupled Langevin equations. Deriving exact expressions for the corresponding steady state probability distributions, we find that the active noise induces an attraction to the edges of the confining domain. In the presence of a competing centering force, we find that the shape of the probability distribution exhibits a sharp transition upon varying the amplitude of the active noise. Our results could help understanding the positioning and deformability of biological inclusions, eg. organelles in cells, or nucleus and cells within tissues.

description: Perceiving the degree of variation in the social and non-social environment is a cognitive task that is important for many judgments and decisions. In the present research, we investigated cognitive underpinnings of how people estimate the average value of segments of a statistical distribution (e.g., what is the average income of the richest 25% of a population?). In three experiments (total N = 222), participants learned about the values of experimentally created distributions of income values and city sizes and later estimated the mean value of the four quarters of values. We expected participants to draw on heuristic shortcuts to generate such judgments. More specifically, we hypothesized that participants use the endpoints of the distributions as anchors and determine the mean values by linear interpolation. In addition, we tested the contribution of three further processes (Range-Frequency adjustments, Normal Smoothing, Linear Smoothing). Quantitative model tests suggest that anchoring and Linear Smoothing both affected mean interquartile judgments. This conclusion is corroborated by tests of qualitative predictions of the models under consideration.

description: We present a covariant multisymplectic formulation for the Einstein-Hilbert model of General Relativity. As it is described by a second-order singular Lagrangian, this is a gauge field theory with constraints. The use of the unified Lagrangian-Hamiltonian formalism is particularly interesting when it is applied to these kinds of theories, since it simplifies the treatment of them; in particular, the implementation of the constraint algorithm, the retrieval of the Lagrangian description, and the construction of the covariant Hamiltonian formalism. In order to apply this algorithm to the covariant field equations, they must be written in a suitable geometrical way, which consists of using integrable distributions, represented by multivector fields of a certain type. We apply all these tools to the Einstein-Hilbert model without and with energy-matter sources. We obtain and explain the geometrical and physical meaning of the Lagrangian constraints and we construct the multimomentum (covariant) Hamiltonian formalisms in both cases. As a consequence of the gauge freedom and the constraint algorithm, we see how this model is equivalent to a first-order regular theory, without gauge freedom. In the case of presence of energy-matter sources, we show how some relevant geometrical and physical characteristics of the theory depend on the type of source. In all the cases, we obtain explicitly multivector fields which are solutions to the gravitational field equations. Finally, a brief study of symmetries and conservation laws is done in this context.
description: 44 pp. The paper has been substantially revised: A new Section (V) about symmetries and conservation laws has been added. Some changes of notation in Section II have been done in order to do it more clear and readable. Some notational errors and misprints have been corrected along the paper. The bibliography is updated and some new references have been added

Is a necessarily necessary God possible?

description: Colloquium presented at The Cave Wall, a student-run philosophy club at Stellenbosch University, covering the modal ontological argument. Given the diverse interdisciplinary audience, I do not assume familiarity with formal logic.

Abstract:

In Prologion III, Anselm presents a famous ontological argument for the existence of God. The argument assumes possibility of the existence of a being whose very existence is necessary,  and from this possibility alone concludes the existence of such a being. On first reading, this argument may appear abstract and unconvincing - in particular, one may doubt whether the conclusion indeed follows from the premiss. Worse still, it is equally difficult to convincingly rebut this argument without first making very precise several hidden assumptions about the modalities of “necessity” and “possibility” upon which the argument depends. 

In this talk, I introduce one framework in which such alethic modal reasoning may be formalised, namely the S5 modal logic. I then formally prove Anselm’s argument in S5, and discuss the implications for the forcefulness of the argument. The main reference for this talk is Philosophical and Mathematical Logic by De Swart (2018).

description: The existence of doubly heavy flavor baryons has not been well established experimentally so far. In this Letter we systematically investigate the weak decays of the doubly charmed baryons, $Ξ_{cc}^{++}$ and $Ξ_{cc}^{+}$, which would be helpful for experimental searches for these particles. The branching fractions are studied under the factorization hypothesis for the short-distance contributions and considering the rescattering effect for the long-distance contributions which are significantly enhanced. Comparing all the decay modes, we recommend the processes of $Ξ_{cc}^{++}\to Λ_c^+K^-π^+π^+$ and $Ξ_c^+π^+$ as the first priority for experiments to search for the doubly heavy baryons.

Sync and Share

description: CERNBox is a cloud synchronisation service for end-users: it allows syncing and sharing files on all major mobile and desktop platforms (Linux, Windows, MacOSX, Android, iOS) aiming to provide offline availability to any data stored in the CERN EOS infrastructure. There is a high demand in the community for an easily accessible cloud storage solution such as CERNBox. Integration of the CERNBox service with the EOS storage back-end is the next step towards providing ’synchronisation and sharing‘ capabilities for scientific and engineering use-cases. CERNBox achieves the integration of ’synchronisation and sharing‘ capabilities with the LHC data analysis tools and transfer services. IT-DSS introduces CERNBox, a synchronisation and sharing service, to promote a new integrated way of accessing data for scientific research.

description: We propose a method using solid state detectors with directional sensitivity to dark matter interactions to detect low-mass Weakly Interacting Massive Particles (WIMPs) originating from galactic sources. In spite of a large body of literature for high-mass WIMP detectors with directional sensitivity, no available technique exists to cover WIMPs in the mass range <1 GeV. We argue that single-electron resolution semiconductor detectors allow for directional sensitivity once properly calibrated. We examine commonly used semiconductor material response to these low-mass WIMP interactions.

description: Das Responsa-Genre als ein zentraler Teilsbereich der jüdischen Rechtsliteratur hat sich über einen Zeitraum von mehr als 1300 Jahren in verschiedenen Kulturräumen dynamisch entwickelt. Der Enzyklopädie-Artikel "Responsa" gibt einen Überblick über Charakteristika und Entwicklungen des Responsa-Genres von seinen Anfängen bis in die Gegenwart, wobei der Fokus auf der rhetorischen Ausgestaltung der Rechtsgutachten liegt. Nach einer Einordnung des Responsa-Genres im Verhältnis zu den anderen Zweigen der jüdischen Rechtsliteratur werden die verschiedenen Epochen und Zentren, die sich im Hinblick auf das Genre ausmachen lassen, sowie die Formen, der Aufbau und Argumentationsmuster gaonäischer Responsa (7.-11. Jh.) und rabbinischer Responsa (ab dem 11. Jh.) vorgestellt. Abschließend beleuchtet der Artikel die im Vergleich zu der etablierten Grundform rabbinischer Responsa grundlegenden Entwicklungen des Responsa-Genres in der Gegenwart.
