description: In modern cosmology, scalar fields with screening mechanisms are often used as explanations for phenomena like dark energy or dark matter. Amongst a zoo of models, the environment dependent dilaton, screened by the Polyakov-Damour mechanism, is one of the least constrained ones. Using recently developed path integral tools for directly computing reduced density matrices, we study the open quantum dynamics of a probe, modelled by another real scalar field, induced by interactions with an environment comprising fluctuations of a dilaton. As the leading effect, we extract a correction to the probe's unitary evolution, which can be observed as a frequency shift. Assuming the scalar probe to roughly approximate a cold atom in matter wave interferometry, we show that comparing the predicted frequency shifts in two experimentally distinct setups has the potential to exclude large parts of the dilaton parameter space.

description: Tissues are highly three-dimensional structure complexes composed of different cell types and their interactions. One of the main challenges in tissue engineering is the inability to produce large, highly perfused scaffolds in which cells can grow at a high cell density and viability. Poly(dimethyl siloxane) (PDMS) is used as a flexible, biocompatible cell culture substrate with tunable mechanical properties. However, its fragility and hydrophobicity still pose a challenge. Here, we present a new strategy for the three-step one-pot synthesis of novel biocompatible hydrophilic copolymers containing siloxane units. In the first step, free radical copolymerization of acrylic acid (AA), butyl methacrylate (BMA), and 2-hydroxyethyl methacrylate (HEMA) was carried out in dioxane (DO) solution in the presence of 2,2′-azodiisobutyronitrile (AIBN). In the second step, the copolymers were modified with diepoxypropoxypropyl-terminated polydimethylsiloxane (DE-PDMS), and in the third step, the copolymers were additionally modified with glycidyl methacrylate (GMA). The modified copolymers were characterized by FTIR, NMR spectroscopy and elemental analysis. Films of modified copolymers were prepared by UV curing. SEM studies revealed microphase separated morphology with distribution of PDMS domains. The mechanical properties of the films depended on the amount of incorporated silicone modifier. The films were more hydrophilic than PDMS films. All novel copolymers showed high biocompatibility.

description: The way people produce, transact, arrange and remunerate labour, distribute, accumulate, possess, and consume is shaped by their social context. Whether in Melbourne or Moresby, the economic is not a separate domain upon which social considerations impinge, but is always embedded within social structures and relationships particular to a place. This is evident in how Melanesians have engaged with cash-earning activities. Local engagements are diverse, but all have reconfigured and reinterpreted introduced ideas, practices and institutions through local practices and understandings (McCormack and Barclay 2013). This means, for instance, that although people are buying and selling, they cannot be assumed to subscribe to the same principles, or possess the same motivations, considerations and challenges as small business in Australia (Curry 2005). This In Brief points to the diverse influences on people's efforts to earn money in Melanesia, and emphasises that understanding these influences is an important starting point for development interventions aimed at improving livelihoods and cultivating entrepreneurship.

description: Abstract: "We present a forward sequent calculus for intuitionistic propositional linear logic ([circle with x], 1, &, T, -o, [circle with plus], 0, !) and a corresponding inverse-method search strategy. Our approach centres around resource management, inspired by similar approaches for backward-directed calculi such as top-down linear logic programming. Surprisingly, the resource management problems for the forward direction turn out to have a different character to those of the backward direction, arising for different connectives. Our approach identifies conditions for which we may relax linearity to allowing (implicit) weakening. We characterize two such classes of affine behaviour -- as a form of weak sequent designed to handle T-weakening lazily, and as affine contexts to control the multiplicative unit 1 using a general matching framework."

description: Photon loss is the fundamental issue towards the development of quantum communication. We present a proposal to mitigate photon loss even at large distances and hence to create a global-scale quantum communication architecture. In this proposal, photons are sent directly through space, using a chain of co-moving low-earth orbit satellites. This satellite chain would bend the photons to move along the earth's curvature and control photon loss due to diffraction by effectively behaving like a set of lenses on an optical table. Numerical modeling of photon propagation through these "satellite lenses" shows that diffraction loss in entanglement distribution can be almost eliminated even at global distances of 20,000 km while considering beam truncation at each satellite and the effect of different errors. In the absence of diffraction loss, the effect of other losses (especially reflection loss) becomes important and they are investigated in detail. The total loss is estimated to be less than 30 dB at 20,000 km if other losses are constrained to 2% at each satellite, with 120 km satellite separation and 60 cm diameter satellite telescopes eliminating diffraction loss. Such low-loss satellite-based optical-relay protocol would enable robust, multi-mode global quantum communication and wouldn't require either quantum memories or repeater protocol. The protocol can also be the least lossy in almost all distance ranges available (200 - 20,000 km). Recent advances in space technologies may soon enable affordable launch facilities for such a satellite-relay network. We further introduce the "qubit transmission" protocol which has a plethora of advantages with both the photon source and the detector remaining on the ground. A specific lens setup was designed for the "qubit transmission" protocol which performed well in simulation that included atmospheric turbulence in the satellite uplink.

Effect of finishing instrumentation on enamel and composite surface morphology and marginal integrity of resin-based composite restorations

Year: 2006

description: This study evaluated the effect of different finishing instruments on enamel and composite surface morphology, and the effects of different finishing instruments on marginal integrity of resin-based composite restorations. Bovine incisors (n=75) embedded in epoxy resin had the facial enamel ground and polished to 1200-grit. A standardized Class V cavity was prepared on each specimen and restored with composite (Z250). Specimens were randomized into fifteen groups (n=5) according to finishing instruments: positive control (coarse diamond), negative control (1200-grit), fine crosscut burs (CC), straight cut burs (StC), spiral cut burs (SpC), and finishing diamonds (FD). StC, SpC, and FD were tested individually as fine, extra-fine, and ultra-fine, and sequentially as a series (cumulative effect). A high-speed, water-cooled handpiece under standardized conditions {(pressure (0.5N) and time (40 s)} was used. Specimens were analyzed for Ra with a mechanical profilometer and observed using scanning electron microscopy (SEM) at x500 magnification for marginal integrity (gap measurement). Data were analyzed using two-way ANOVA and the Duncan test. Statistically significant differences (p<0.05) were detected among the finishing instruments. The positive control surface created by the diamond medium band bur generated the roughest surface, while the negative control surface created with the mechanically polished enamel generated the smoothest surfaces. When compared with the negative control group, StC all series, SpC all series, and FD fine were observed to have a statistically significant difference in surface roughness. These three groups presented higher Ra values when compared with the other groups. For the marginal integrity, there was no statistically significant difference between FD and the negative control. However, the positive control exhibited significantly larger gaps when compared to the other finishing instruments. Intermediate results were observed for CC, StC and SpC. FD (fine, extra-fine and ultra-fine) generated smaller gaps compared to carbides and regular-grit diamonds. Finishing diamonds: fine, extra-fine and ultra-fine, generated smaller gaps compared to carbides and regular-grit diamonds.

description: The organizer of a machine learning competition faces the problem of maintaining an accurate leaderboard that faithfully represents the quality of the best submission of each competing team. What makes this estimation problem particularly challenging is its sequential and adaptive nature. As participants are allowed to repeatedly evaluate their submissions on the leaderboard, they may begin to overfit to the holdout data that supports the leaderboard. Few theoretical results give actionable advice on how to design a reliable leaderboard. Existing approaches therefore often resort to poorly understood heuristics such as limiting the bit precision of answers and the rate of re-submission. In this work, we introduce a notion of leaderboard accuracy tailored to the format of a competition. We introduce a natural algorithm called the Ladder and demonstrate that it simultaneously supports strong theoretical guarantees in a fully adaptive model of estimation, withstands practical adversarial attacks, and achieves high utility on real submission files from a Kaggle competition. Notably, we are able to sidestep a powerful recent hardness result for adaptive risk estimation that rules out algorithms such as ours under a seemingly very similar notion of accuracy. On a practical note, we provide a completely parameter-free variant of our algorithm that can be deployed in a real competition with no tuning required whatsoever.

description: We introduce a new class of noncommutative spectral triples on Kellendonk's $C^*$-algebra associated with a nonperiodic substitution tiling. These spectral triples are constructed from fractal trees on tilings, which define a geodesic distance between any two tiles in the tiling. Since fractals typically have infinite Euclidean length, the geodesic distance is defined using Perron-Frobenius theory, and is self-similar with scaling factor given by the Perron-Frobenius eigenvalue. We show that each spectral triple is $θ$-summable, and respects the hierarchy of the substitution system. To elucidate our results, we construct a fractal tree on the Penrose tiling, and explicitly show how it gives rise to a collection of spectral triples.

description: This document is a report of Milestone MS 16 of the Co-UDlabs project, funded under the European Union’s Horizon 2020 research and innovation programme and under Grant Agreement No 101008626. The primary method for defect identification and classification is based around using CCTV to collect images and then these are used for subsequent analysis. In the later analysis images are normally manually inspected and defects are classified according to a standard classification. The defect classification methods used in European countries are different, but have a similar structure, which reflects their historical development and is described in EN13508:Part2. The current national defect classification schemes are generally complex involving a large number of defect codes. Considering the various defect classification codes across Europe the number of unique defect codes is now greater than 300. In contrast in Japan the defect coding system contains just 10 defect types. There are a number of academic studies and more recent companies that are developing data-driven classifiers to link observed defects with a defect classification code. These studies have shown some promise but have resulted in collection of large numbers of images. This report describe the outcome of work to consider what knowledge could be gained from a more straightforward defect classification approach. This report presents a deep-learning based framework for the automated detection of in-pipe defects in closed-circuit television (CCTV) sewer surveys. The framework utilizes the Ultralytics YOLO v8 model for image processing and defect detection. By eliminating the need for manual feature extraction, this approach simplifies the identification of defects that are challenging to extract features from, such as those found in sewer pipes. The report outlines the methodology, demonstration results, and provides recommendations for further work. All the source code is open access and has been developed to a standard to encourage other, especially non-specialists in small companies and utilities to try and investigate whether a more simplified defect classification scheme can provide the knowledge needed to enhance their management of buried sewer assets. All the code is publically available, with sample images and written software support to allow ease of access. The team at Sheffield will continue to develop this open access approach to software development and encourage those that use the code and uploaded images to report on their findings.

description: This study examined perceptions of indoor tanning behavior and anti-tanning messaging among college-aged women in order to better understand what types of messages and message elements might be effective in persuading young women to not tan indoors. Two focus groups were conducted with participants who tan indoors either currently or who have tanned indoors in the past. Participants discussed benefits and harms of tanning indoors, and the relative effectiveness of several narrative and non-narrative anti-tanning messages. The results of this study suggest that young women believe there to be significant benefits and harms from tanning indoors. Results also point to several strategies for future anti-tanning message design, including the importance of presenting a threat that is perceived as both real and highly possible for individuals who tan indoors, using key informants who have personal experiences with indoor tanning and its harmful outcomes, and with whom target audiences can identify.

description: My current research seeks to build a profile of young Melanesian women identified by their peers and fellow national citizens as playing leading roles in their families, communities and beyond. There is an enormous amount of attention given to getting women into politics, but we know comparatively little about how young women think about politics, and the ways in which they choose to engage with the formal political system. It is important to be alert to the ways in which young women demonstrate leadership outside the formal political system, for example, as entrepreneurs or through community or volunteer work. This In Brief discusses preliminary findings from recent fieldwork in Solomon Islands, where I interviewed young women leaders. I was fortunate to be able to contact these dynamic women through the Young Women's Parliamentary Group (YWPG).

description: Pixelated CdZnTe detectors are a promising imaging-spectrometer for gamma-ray astrophysics due to their combination of relatively high energy resolution with room temperature operation negating the need for cryogenic cooling. This reduces the size, weight, and power requirements for telescope-based radiation detectors. Nevertheless, operating CdZnTe in orbit will expose it to the harsh radiation environment of space. This work, therefore, studies the effects of $61 \ \mathrm{MeV}$ protons on $2 \times 2 \times 1 \ \mathrm{cm}^3$ pixelated CdZnTe and quantifies proton-induced radiation damage of fluences up to $2.6 \times 10^8 \ \mathrm{p/cm^2}$. In addition, we studied the effects of irradiation on two separate instruments: one was biased and operational during irradiation while the other remained unbiased. Following final irradiation, the $662 \ \mathrm{keV}$ centroid and nominal $1\%$ resolution of the detectors were degraded to $642.7 \ \mathrm{keV}, 4.9 \% \ ( \mathrm{FWHM})$ and $653.8 \ \mathrm{keV}, 1.75 \% \ (\mathrm{FWHM})$ for the biased and unbiased systems respectively. We therefore observe a possible bias dependency on proton-induced radiation damage in CdZnTe. This work also reports on the resulting activation and recovery of the instrument following room temperature and $60^{\circ}\mathrm{C}$ annealing.

description: A topological space $X$ has the strong Pytkeev property at a point $x\in X$ if there exists a countable family $\mathcal N$ of subsets of $X$ such that for each neighborhood $O_x\subset X$ and subset $A\subset X$ accumulating at $x$, there is a set $N\in\mathcal N$ such that $N\subset O_x$ and $N\cap A$ is infinite. We prove that for any $\aleph_0$-space $X$ and any space $Y$ with the strong Pytkeev property at a point $y\in Y$ the function space $C_k(X,Y)$ has the strong Pytkeev property at the constant function $X\to \{y\}\subset Y$. If the space $Y$ is rectifiable, then the function space $C_k(X,Y)$ is rectifiable and has the strong Pytkeev property at each point. We also prove that for any pointed spaces $(X_n,*_n)$, $n\inω$, with the strong Pytkeev property their Tychonoff product and their small box-product both have the strong Pytkeev property at the distinguished point. We prove that a sequential rectifiable space $X$ has the strong Pytkeev property if and only if $X$ is metrizable or contains a clopen submetrizable $k_ω$-subspace. A locally precompact topological group is metrizable if and only if it contains a dense subgroup with the strong Pytkeev property.

description: We prove a bound for quintilinear sums of Kloosterman sums, with congruence conditions on the "smooth" summation variables. This generalizes classical work of Deshouillers and Iwaniec, and is key to obtaining power-saving error terms in applications, notably the dispersion method. As a consequence, assuming the Riemann hypothesis for Dirichlet $L$-functions, we prove a power-saving error term in the Titchmarsh divisor problem of estimating $\sum_{p\leq x}τ(p-1)$. Unconditionally, we isolate the possible contribution of Siegel zeroes, showing it is always negative. Extending work of Fouvry and Tenenbaum, we obtain power-saving in the asymptotic formula for $\sum_{n\leq x}τ_k(n)τ(n+1)$, reproving a result announced by Bykovskiĭ and Vinogradov by a different method. The gain in the exponent is shown to be independent of $k$ if a generalized Lindelöf hypothesis is assumed.

description: By applying artificial intelligence to image editing technology, it has become possible to generate high-quality images with minimal traces of manipulation. However, since these technologies can be misused for criminal activities such as dissemination of false information, destruction of evidence, and denial of facts, it is crucial to implement strong countermeasures. In this study, image file and mobile forensic artifacts analysis were conducted for detecting image manipulation. Image file analysis involves parsing the metadata of manipulated images (e.g., Exif, DQT, and Filename Signature) and comparing them with a Reference DB to detect manipulation. The Reference DB is a database that collects manipulation-related traces left in image metadata, which serves as a criterion for detecting image manipulation. In the mobile forensic artifacts analysis, packages related to image editing tools were extracted and analyzed to aid the detection of image manipulation. The proposed methodology overcomes the limitations of existing graphic feature-based analysis and combines with image processing techniques, providing the advantage of reducing false positives. The research results demonstrate the significant role of such methodology in digital forensic investigation and analysis. Additionally, We provide the code for parsing image metadata and the Reference DB along with the dataset of manipulated images, aiming to contribute to related research.

description: The reaction mechanisms for neutrino interactions with an $^{40}Ar$ nucleus with the LBNF flux are calculated with the Giessen-Boltzmann-Uehling-Uhlenbeck (GiBUU) transport-theoretical implementation of these interactions. Quasielastic scattering, many-body effects, pion production and absorption and Deep Inelastic Scattering are discussed; they all play a role at the LBNF energies and are experimentally entangled with each other. Quasielastic scattering makes up for only about 1/3 of the total cross section whereas pion production channels make up about 2/3 of the total. This underlines the need for a consistent description of the neutrino-nucleus reaction that treats all channels on an equal, consistent footing. The results discussed here can also serve as useful guideposts for the Intermediate Neutrino Program.

Comparison of conventional and Cone Beam CT synthesized cephalograms

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: The purpose of this study was to determine whether Cone Beam Computed Tomography (CBCT) synthesized cephalograms provide the same measurement accuracy and precision as conventional cephalograms. In Part I, cephalometric measurements of conventional and CBCT synthesized orthogonal or perspective projections of 10 skulls were compared with each other and with the actual skull measurements. In Part II, actual patient data was used to compare the three imaging modalities and both soft and hard tissue landmarks were utilized. This study demonstrated that most cephalometric measurements are not different for conventional and CBCT synthesized orthogonal and the perspective projections. Although there is a statically significant difference between mid-sagittal image measurements compared to actual skull measurements, these differences are very small .and are unlikely to have clinical relevance. Both of the projections can be used with an expectation of precision and accuracy similar to conventional cephalograms.
Complete Equational Theories for the Sum-Over-Paths with Unbalanced Amplitudes

description: Vilmart recently gave a complete equational theory for the balanced sum-over-paths over Toffoli-Hadamard circuits, and by extension Clifford+Rz(2pi/2^k) circuits. Their theory is based on the phase-free ZH-calculus which crucially omits the average rule of the full ZH-calculus, dis-allowing the local summation of amplitudes. Here we study the question of completeness in unbalanced path sums which naturally support local summation. We give a concrete syntax for the unbalanced sum-over-paths and show that, together with symbolic multilinear algebra and the interference rule, various formulations of the average and ortho rules of the ZH-calculus are sufficient to give complete equational theories over arbitrary rings and fields.

description: This paper describes a novel approach to powering
a radical type of microrobot. Our long-term aim is to enable
the construction of ensembles of millions of coordinated nearspherical,
submillimeter microrobots. Both the large number
of potential simultaneous neighbors of each robot (12) and the
difficulty of fine actuation at such small scales preclude the use
of complex connectors previously developed in many modular
robotics efforts. Instead, we propose to leverage multirobot
cooperation to simplify the mechanics of modular robot docking.

In our approach, the robots actively cooperate to route virtual
power busses (both supply and ground) to all the robots in
the ensemble using only unary (single conductor) electrical
connectors between robots. A unary connector allows for larger
tolerances in engagement angle, simplifies robot manufacture,
speeds reconfiguration, and maximizes the proportion of the
connector surface area useful for carrying current. The algorithms
we present permit a robot ensemble to efficiently harvest
and distribute power from sources discovered in the environment
and/or carried by the ensemble. We evaluate these algorithms
in a variety of simulated deployment conditions and report on
the impact of hardware defects, limited on-board power storage,
and the ensemble-environment interface.

description: Successfully modeling state and analytics-based semantic relationships of documents enhances representation, importance, relevancy, provenience, and priority of the document. These attributes are the core elements that form the machine-based knowledge representation for documents. However, modeling document relationships that can change over time can be inelegant, limited, complex or overly burdensome for semantic technologies. In this paper, we present Direct Qualification (DQ), an approach for modeling any semantically referenced document, concept, or named graph with results from associated applied analytics. The proposed approach supplements the traditional subject-object relationships by providing a third leg to the relationship; the qualification of how and why the relationship exists. To illustrate, we show a prototype of an event-based system with a realistic use case for applying DQ to relevancy analytics of PageRank and Hyperlink-Induced Topic Search (HITS).

description: The inevitable proliferation of expert systems underscores the
need for robust, friendly interfaces requiring minimal user
training. The objective of the XCALIBUR project is to meet this
need by providing natural comprehension and generation in the
context of a focused mixed-initiative dialog. The XCALIBUR
architecture is discussed, including its three central components
(parser, generator and information manager), its methods of
handling ellipsis and imperfect input, and its relation to the
underlying expert system.
High-resolution emission spectroscopy retrievals of MASCARA-1b with CRIRES+: Strong detections of CO, H$_2$O and Fe emission lines and a C$/$O consistent with solar

description: The characterization of exoplanet atmospheres has proven to be successful using high-resolution spectroscopy. Phase curve observations of hot/ultra-hot Jupiters can reveal their compositions and thermal structures, thereby allowing the detection of molecules and atoms in the planetary atmosphere using the cross-correlation technique. We present pre-eclipse observations of the ultra-hot Jupiter, MASCARA-1b, observed with the recently upgraded CRIRES+ high-resolution infrared spectrograph at the VLT. We report a detection of $\rm Fe$ ($\approx$8.3$σ$) in the K-band and confirm previous detections of $\rm CO$ (>15$σ$) and $\rm H_2O$ (>10$σ$) in the day-side atmosphere of MASCARA-1b. Using a Bayesian inference framework, we retrieve the abundances of the detected species and constrain planetary orbital velocities, $T$-$P$ profiles, and the carbon-to-oxygen ratio ($\rm C/O$). A free retrieval results in an elevated $\rm CO$ abundance ($\log_{10}$($χ_{\rm{{}^{12}CO}}$) = $-2.85^{+0.57}_{-0.69}$), leading to a super-solar $\rm C/O$ ratio. More realistically, allowing for vertically-varying chemistry in the atmosphere by incorporating a chemical-equilibrium model results in a $\rm C/O$ of $0.68^{+0.12}_{-0.22}$ and a metallicity of $[\rm M/H] = 0.62^{+0.28}_{-0.55}$, both consistent with solar values. Finally, we also report a slight offset of the $\rm Fe$ feature in both K$_{\rm p}$ and v$_{\rm sys}$ that could be a signature of atmospheric dynamics. Due to the 3D structure of exoplanet atmospheres and the exclusion of time/phase dependence in our 1D forward models, further follow-up observations and analysis are required to confirm or refute this result.

Association between RyR and FKBP in experimental preparations: evidence for negative cooperativity
Creators: name: Richardson, Spencer

description: Ryanodine receptors (RyR), a class of massive tetrameric intracellular ion channels, are an indispensable element of excitation-contraction coupling, governing the release of Ca2+ from the sarcoplasmic reticulum (SR). FK506-binding proteins (FKBP), a class of soluble proteins named for their affinity to the immunosuppressant drug FK506, have long been known to bind RyR endogenously, at a stoichiometry of one FKBP per RyR monomer. Much is unknown regarding the relationship between the two species, however: for example, it is not known whether FKBP-binding sites on the RyR are fully occupied in normal physiology, or whether instead there might be a dynamic aspect to the association between the two proteins. In this thesis, the relationship between the two most prominent isoforms of RyR, RyR1 and RyR2, and their endogenous ligands, FKBP12 and FKBP12.6, is examined via biochemical experiments. The effects of FKBP-dissociating treatments, saturation of RyR by exogenous FKBP, and the effects of the FKBP-RyR stabilising drug S107 are all examined in depth, with additional observations made on the dimerisation of GST-FKBP12 and FKBP12 and the effects of SR vesicle processing on the association between RyR and FKBP. These experiments give rise to some surprising results: FKBP-dissociating treatments have very different effects on RyR1 and RyR2, and while considerable FKBP is lost from RyR during the preparation of SR vesicles, it appears that RyR may not be endogenously saturated with FKBP. Finally, drawing on observations made during the biochemical experiments comprising this thesis, one particularly interesting model of a relationship between RyR and FKBP will be explored in greater depth: negative cooperation between the two species, wherein each molecule of FKBP binding to a RyR tetramer renders any subsequent binding less likely. This model is reconciled with the existing literature, and intriguing preliminary data is presented in support of negative cooperativity.

description: Rational choice theory in criminology is based on a model of decision-making, expected utility theory (EUT), that research in psychology and economics has shown to be descriptively inaccurate for many types of human decisions. Because of its ability to account for intuitive reasoning and anomalies in crime decisions, prospect theory (PT) may be a viable alternative to EUT for explaining criminal choices. The present study tests several hypotheses derived from PT about the effects of framing, reference dependence, and decision weights in crime decisions. We present findings from a series of survey-based experiments conducted with three different samples. The results support our hypotheses derived from EUT, but not those from PT. We find that although initial wealth, criminal benefits, and arrest risk impact offender decision-making, sanction-cost frames and gains/losses from monetary reference points have little if any effect. We discuss the implications of our findings and directions for future research.
Broadband composite polarization rotator

description: We describe a broadband optical device that is capable of rotating the polarization plane of a linearly polarized light at any desired angle over a wide range of wavelengths. The device is composed of a sequence of half-wave plates rotated at specific angles with respect to their fast-polarization axes. This design draws on an analogy with composite pulses, which is a well-known control technique from quantum physics. We derive the solutions for the rotation angles of the single half-wave plates depending on the desired polarization rotation angle. We show that the broadband polarization rotator is robust against variations of the parameters of both the crystal and the light field.
Strangers in Their Own Communities: Second-Generation Jews in Divided Germany, 1945-1989

description: This thesis employs a comparative approach to examine the efforts of young Jews in Frankfurt am Main and East Berlin to create new Jewish spaces that existed beyond those of the official Jewish Communities in their respective countries. Despite growing up in drastically different Germanys, the founding members of the Jüdische Gruppe (Frankfurt) and Wir für uns – Juden für Juden (East Berlin) challenged the Jewish establishment by calling for greater religious pluralism and re-imagining the ideological basis for the continued existence of Jewish life in Germany after the Holocaust. In addition to providing a more unified approach to the history of Jewish life in postwar Germany, this thesis sheds light on the postwar efforts of European Jews to grapple with the concepts of exile and diaspora, as well as Jewish reactions to societal changes in the Federal Republic of Germany and the German Democratic Republic.
