description: Exchange interactions with itinerant electrons are known to act as a relaxation mechanism for individual local spins. The same exchange interactions are also known to induce the so called RKKY indirect exchange interaction between two otherwise decoupled local spins. Here we show that both the spin relaxation and the RKKY coupling can be seen as the dissipative and reactive response to the coupling of the local spins with the itinerant electrons. We thereby predict that the spin relaxation rates of magnetic nanostructures of exchanged coupled local spins, such as as nanoengineered spin chains, have an oscillatory dependence on $k_F d$ , where $k_F$ is the Fermi wave length and $d$ is the inter-spin distance, very much like the celebrated oscillations in the RKKY interaction. We demonstrate that both $T_1$ and $T_2$ can be enhanced or suppressed, compared to the single spin limit, depending on the interplay between the Fermi surface and the nanostructure geometrical arrangement. Our results open a route to engineer spin relaxation and decoherence in atomically designed spin structures.

description: Inspired by the idea of mimicking the measurement on a quantum system through a decoherence process to target specific eigenstates based on Born's law, i.e. the hiearchy of probabilities instead of the hierarchy of eigenvalues, we transform a Lindblad equation for the reduced density operator into a nonlinear Schrödinger equation to obtain a computationally feasible simulation of the decoherent dynamics in the open quantum system. This gives the opportunity to target the eigenstates which have the largest $L^2$ overlap with an initial superposition state and hence more flexibility in the selection criteria. One can use this feature for instance to approximate eigenstates with certain localization or symmetry properties. As an application of the theory we discuss \textit{eigenstate towing}, which relies on the perturbation theory to follow the progression of an arbitrary subset of eigenstates along a sum of perturbation operators with the intention to explore for example the effect of interactions on these eigenstates. The easily parallelizable numerical method shows an exponential convergence and its computational costs scale linear for sparse matrix representations of the involved Hermitian operators.

description: We present experiments on ensemble cavity quantum electrodynamics with cold potassium atoms in a high-finesse ring cavity. Potassium-39 atoms are cooled in a two-dimensional magneto-optical trap and transferred to a three-dimensional trap which intersects the cavity mode. The apparatus is described in detail and the first observations of strong coupling with potassium atoms are presented. Collective strong coupling of atoms and light is demonstrated via the splitting of the cavity transmission spectrum and the avoided crossing of the normal modes.

Dabei zeigt sich bei den Wohnungsmieten eine Zunahme der regionalen Streuung im Zeitverlauf vor allem in der auf die Finanzkrise 2007–2009 folgenden Zeit. Bei der Preis-Miet-Relation nimmt die Streuung im Zeitverlauf ab 2010 ebenfalls zu. Im Durchschnitt der Regionen (Landkreise und kreisfreie Städte) steigen über den gesamten Zeitabschnitt die Mieten und in der überwiegenden Zahl der Regionen auch die Preis-Miet-Relation (allerdings erst ab 2010); sie entwickeln sich aber regional stark unterschiedlich. Dies führt auch zur Zunahme der Variationskoeffizienten, also der relativen Streuung der regionalen Mieten und – ab 2010 – auch der regionalen Preis-Miet-Relationen. Dies deutet auf eine Zunahme der regionalen Disparitäten in der Bundesrepublik Deutschland hin. Besondere Divergenzen zeigen sich zwischen den alten und den neuen Bundesländern, wie auch zwischen prosperierenden kreisfreien Städten und deren Umland und ökonomisch schwächeren Städten und Landkreisen.

description: We use the largest sample of z~6 galaxies to date from the first four Hubble Frontier Fields clusters to set constraints on the shape of the z~6 luminosity functions (LFs) to fainter than Muv=-14 mag. We quantify, for the first time, the impact of magnification uncertainties on LF results and thus provide more realistic constraints than other recent work. Our simulations reveal that for the highly-magnified sources the systematic uncertainties can become extremely large fainter than -14 mag, reaching several orders of magnitude at 95% confidence at ~-12 mag. Our new forward-modeling formalism incorporates the impact of magnification uncertainties into the LF results by exploiting the availability of many independent magnification models for the same cluster. One public magnification model is used to construct a mock high-redshift galaxy sample that is then analyzed using the other magnification models to construct a LF. Large systematic errors occur at high magnifications (mu>30) because of differences between the models. The volume densities we derive for faint (>-17 mag) sources are ~3-4x lower than one recent report and give a faint-end slope alpha=-1.92+/-0.04, which is 3.0-3.5sigma shallower (including or not including the size uncertainties, respectively). We introduce a new curvature parameter delta to model the faint end of the LF and demonstrate that the observations permit (at 68% confidence) a turn-over at z~6 in the range -15.3 to -14.2 mag, depending on the assumed lensing model. The present consideration of magnification errors and new size determinations raise doubts about previous reports regarding the form of the LF at >-14 mag. We discuss the implications of our turn-over constraints in the context of recent theoretical predictions.

description: An open question of fundamental importance in thermodynamics is how to describe the fluctuations of work for quantum coherent processes. In the standard approach, based on a projective energy measurement both at the beginning and at the end of the process, the first measurement destroys any initial coherence in the energy basis. Here we seek for extensions of this approach which can possibly account for initially coherent states. We consider all measurement schemes to estimate work and require that (i) the difference of average energy corresponds to average work for closed quantum systems, and that (ii) the work statistics agree with the standard two-measurement scheme for states with no coherence in the energy basis. We first show that such a scheme cannot exist. Next, we consider the possibility of performing collective measurements on several copies of the state and prove that it is still impossible to satisfy simultaneously requirements (i) and (ii). Nevertheless, improvements do appear, and in particular we develop a measurement scheme which acts simultaneously on two copies of the state and allows to describe a whole class of coherent transformations.

description: The Queensland Basic Paediatric Training Network (QBPTN) is responsible for the selection of candidates into paediatric training in Queensland. The COVID-19 pandemic necessitated interviews to be conducted ‘virtually’ as virtual Multiple-Mini-Interviews (vMMI). The study aimed to describe the demographic characteristics of candidates applying for selection into paediatric training in Queensland, and to explore their perspectives and experiences with the vMMI selection tool. The demographic characteristics of candidates and their vMMI outcomes were collected and analysed with a mixed methods approach. The qualitative component was comprised of seven semi-structured interviews with consenting candidates. Seventy-one shortlisted candidates took part in vMMI and 41 were offered training positions. The demographic characteristics of candidates at various stages of selection were similar. The mean vMMI scores were not statistically different between candidates from the Modified Monash Model 1 (MMM1) location and others [mean (SD): 43.5 (5.1) versus 41.7 (6.7), respectively, p = 0.26]. However, there was a statistically significant difference (p value 0.03) between being offered and not offered a training position for candidates from MMM2 and above. The analysis of the semi-structured interviews suggested that candidate experiences of the vMMI were influenced by the quality of the management of the technology used. Flexibility, convenience, and reduced stress were the main factors that influenced candidates’ acceptance of vMMI. Perceptions of the vMMI process focused on the need to build rapport and facilitate communication with the interviewers. vMMI is a viable alternative to face-to-face (FTF) MMI. The vMMI experience can be improved by facilitating enhanced interviewer training, by making provision for adequate candidate preparation and by having contingency plans in place for unexpected technical challenges. Given government priorities in Australia, the impact of candidates’ geographical location on the vMMI outcome for candidates from MMM >1 location needs to be further explored.

description: We prove a local law in the bulk of the spectrum for random Gram matrices $XX^*$, a generalization of sample covariance matrices, where $X$ is a large matrix with independent, centered entries with arbitrary variances. The limiting eigenvalue density that generalizes the Marchenko-Pastur law is determined by solving a system of nonlinear equations. Our entrywise and averaged local laws are on the optimal scale with the optimal error bounds. They hold both in the square case (hard edge) and in the properly rectangular case (soft edge). In the latter case we also establish a macroscopic gap away from zero in the spectrum of $XX^*$.

Enhancing Big Data in the Social Sciences with Crowdsourcing: Data Augmentation Practices, Techniques, and Opportunities

description: The importance of big data is a contested topic among social scientists. Proponents claim it will fuel a research revolution, but skeptics challenge it as unreliably measured and decontextualized, with limited utility for accurately answering social science research questions. We argue that social scientists need effective tools to quantify big data's measurement error and expand the contextual information associated with it. Standard research efforts in many fields already pursue these goals through data augmentation, the systematic assessment of measurement against known quantities and expansion of extant data by adding new information. Traditionally, these tasks are accomplished using trained research assistants or specialized algorithms. However, such approaches may not be scalable to big data or appease its skeptics. We consider a third alternative that may increase the validity and value of big data: data augmentation with online crowdsourcing. We present three empirical cases to illustrate the strengths and limits of crowdsourcing for academic research, with a particular eye to how they can be applied to data augmentation tasks that will accelerate acceptance of big data among social scientists. The cases use Amazon Mechanical Turk to 1. verify automated coding of the academic discipline of dissertation committee members, 2. link online product pages to a book database, and 3. gather data on mental health resources at colleges. In light of these cases, we consider the costs and benefits of augmenting big data with crowdsourcing marketplaces and provide guidelines on best practices. We also offer a standardized reporting template that will enhance reproducibility.

description: Proteins have vital roles in the living cells. The protein function is almost completely dependent on protein structure. The prediction of relative solvent accessibility gives helpful information for the prediction of tertiary structure of a protein. In recent years several relative solvent accessibility (RSA) prediction methods including those that generate real values and those that predict discrete states have been developed. The proposed method consists of two main steps: the first one, provided subset selection of quantitative features based on selected qualitative features and the second, dedicated to train a model with selected quantitative features for RSA prediction. The results show that the proposed method has an improvement in average prediction accuracy and training time. The proposed method can dig out all the valuable knowledge about which physicochemical features of amino acids are deemed more important in prediction of RSA without human supervision, which is of great importance for biologists and their future researches.

description: Objective structured clinical examinations (OSCE) are one of the main modalities of skills’ assessment of medical students. We aimed to evaluate the educational value of the participation of third-year medical students in OSCE as standardized patients. We conducted a pilot OSCE session where third-year students participated in sixth-year students’ OSCE as standardized patients (cases). Their scores in their own subsequent OSCE exams were compared with third-year students who had not participated (controls). Students’ perceptions (stress, preparedness, ease) regarding their OSCE were compared with self-administered questionnaires. A total of 42 students were included (9 cases and 33 controls). Median [IQR] overall score (out of 20 points) obtained by the cases was 17 [16.3–18] versus 14.5 [12.7–16.3] for controls (p < 0.001). Students’ perception of their evaluation (difficulty, stress, communication) was not significantly different between cases and controls. Most cases agreed that their participation was beneficial in reducing their stress (67%), increasing their preparedness (78%) and improving their communication skills (100%). All cases agreed that this participation should be offered more widely. Students’ participation in OSCE as standardized patients led to better performance on their own OSCE and were considered beneficial. This approach could be more broadly generalized to improve student performance.

description: Ursolic acid (UA) is a pentacyclic triterpenoid carboxylic acid that is found in plants and herbal products. It is one of the chemopreventive agents, which can suppress cancer cell proliferation and induce apoptosis. UA possesses various biological activities including anticancer, anti-inflammatory, anti-oxidative and hepatoprotective activity. We investigated the effect of UA on cytokine production via the MAPK pathways in Jurkat leukemic T-cells, showing that UA inhibited cell growth and proliferation of Jurkat cells, as well as suppressing PMA/PHA induced IL-2 and TNF-α production in a concentration and time dependent manner. The inhibition of IL-2 and TNF-α production by UA involved the c-Jun N-terminal kinase (JNK) pathway, but not the extracellular-signal regulated protein kinase (ERK) pathway. Future utilization of UA as a chemopreventive or therapeutic agent may provide an alternative option for leukemia treatments.

description: The Isatis species has antibacterial, anticancer and antiviral properties and these important endemic plants grow widely in various parts of Anatolian-Turkey. In the present study, the antioxidant activities of Isatis floribunda Boiss. ex Bornm. flower and root extracts were determined with total antioxidant activity, free radical scavenging activity, ferric ion reducing power, and cupric ion reducing antioxidant capacity assay. The total phenolic compounds and flavonoids were also examined for the extracts. The antimicrobial activities of the extracts were investigated by using the disc diffusion and microdilution-broth methods against human and fish pathogen microorganisms. The phenolic composition of I. floribunda root methanolic extract was analyzed by high performance liquid chromatography (HPLC). The major component in the extract was cholorogenic acid (1980.20 μg/g). The cytotoxic effect of the methanolic root extract was also tested on human breast cell (MCF12A). The results showed that I. floribunda could be used as a natural source in the food and feed industry and clinical and food chemistry, and that the antimicrobial agents could be used against human and fish pathogens.

description: Four series of di-flouro, namely; 4-substituted phenylazo-3-flouro phenyl-4′-n-alkoxy 3-flouro phenylazo benzoates (Ina-d) based on aromatic rings with the azo/ester/azo linkages core, were prepared and investigated for their mesomorphic properties. An alkoxy group with chain length varied from n = 6 to 16 is attached to the terminal phenylazobenzoate moiety and the other terminal is a compact group (X = –CH3O, –CH3, H and Br) attached to phenylazo moiety. The mesophases were investigated by DSC and POM and compared with previously investigated dilaterally methyl substituted analogues. Terminally unsubstituted and Br substituted analogues displayed dimorphic N and SmA phases, except the lower homologue (n = 6), while terminally – CH3O analogues exhibited monomorphic N phase. For terminally – CH3 substituted, compounds with n = 6–12 exhibited only N phase, while compounds with n = 14 and 16 displayed N and SmA phases. Meanwhile, the dilateral F substituents result in an enhancement in clearing thermal transitions compared with dilateral methyl substituents with a wide mesophase range. TGA analysis revealed that the prepared compounds are thermally stable within mesophase temperature range, except – CH3O, –CH3 and Br derivatives with n = 6. Binary mixtures of I6a-d/I16a-d derivatives were investigated. The photo-physical property was also studied.

description: The field equations for static EGBM gravity are obtained and transformed to an equivalent form through a coordinate redefinition. A form for one of the metric potentials that generalises the spheroidal ansatz of Vaidya--Tikekar superdense stars and additionally prescribing the electric field intensity yields viable solutions. Some special cases of the general solution are considered and analogous classes in the Einstein framework are studied. In particular the Finch--Skea ansatz is examined in detail and found to satisfy the elementary physical requirements. These include positivity of pressure and density, the existence of a pressure free hypersurface marking the boundary, continuity with the exterior metric, a subluminal sound speed as well as the energy conditions. Moreover, the solution possesses no coordinate singularities. It is found that the impact of the Gauss--Bonnet term is to correct undesirable features in the pressure profile and sound speed index when compared to the equivalent Einstein gravity model. Furthermore graphical analyses suggest that higher densities are achievable for the same radial values when compared to the 5--dimensional Einstein case. The case of a constant gravitational potential, isothermal distribution as well as an incompressible fluid are studied. All exact solutions derived exhibit an equation of state explicitly.

description: We propose an ultra-compact polarisation converter based on liquid crystal (LC) material for effectively converting the obliquely incident unpolarised light into horizontal linearly polarised beam within the visible frequency range. Multilayer twisted configuration is introduced here to tackle the inherent dispersion issue from the LC itself and extended Jones matrix is employed to analyse the propagation of the electric field inside the LC medium under possible oblique illumination. Spatial angular separation of orthogonal polarised lights and polarisation conversion into the same polarisation direction are realised through specific patterned structure design, which effectively reduce the thickness of the device without sacrificing performance. Experimental results demonstrated that our fabricated LC-based device can deliver >80% polarisation conversion efficiency at normal illumination and 59%–80.5% efficiency for ±10° oblique incidence over the visible spectrum. Therefore, we envision that our presented device might find numerous potential applications associated with polarisation regulation such as vortex beam generator, augmented reality and optical computing.

description: The "interpretation through synthesis" approach to analyze face images, particularly Active Appearance Models (AAMs) method, has become one of the most successful face modeling approaches over the last two decades. AAM models have ability to represent face images through synthesis using a controllable parameterized Principal Component Analysis (PCA) model. However, the accuracy and robustness of the synthesized faces of AAM are highly depended on the training sets and inherently on the generalizability of PCA subspaces. This paper presents a novel Deep Appearance Models (DAMs) approach, an efficient replacement for AAMs, to accurately capture both shape and texture of face images under large variations. In this approach, three crucial components represented in hierarchical layers are modeled using the Deep Boltzmann Machines (DBM) to robustly capture the variations of facial shapes and appearances. DAMs are therefore superior to AAMs in inferencing a representation for new face images under various challenging conditions. The proposed approach is evaluated in various applications to demonstrate its robustness and capabilities, i.e. facial super-resolution reconstruction, facial off-angle reconstruction or face frontalization, facial occlusion removal and age estimation using challenging face databases, i.e. Labeled Face Parts in the Wild (LFPW), Helen and FG-NET. Comparing to AAMs and other deep learning based approaches, the proposed DAMs achieve competitive results in those applications, thus this showed their advantages in handling occlusions, facial representation, and reconstruction.

description: In this paper, we study the holographic models of s-wave and p-wave Josephoson junction away from probe limit in (3+1)-dimensional spacetime, respectively. With the backreaction of the matter, we obtained the anisotropic black hole solution with the condensation of matter fields. We observe that the critical temperature of Josephoson junction decreases with increasing backreaction. In addition to this, the tunneling current and condenstion of Josephoson junction become smaller as backreaction grows larger, but the relationship between current and phase difference still holds for sine function. Moreover, condenstion of Josephoson junction deceases with increasing width of junction exponentially.

description: The Sachdev-Ye-Kitaev model is a $(0+1)$-dimensional model describing Majorana fermions or complex fermions with random interactions. This model has various interesting properties such as approximate local criticality (power law correlation in time), zero temperature entropy, and quantum chaos. In this article, we propose a higher dimensional generalization of the Sachdev-Ye-Kitaev model, which is a lattice model with $N$ Majorana fermions at each site and random interactions between them. Our model can be defined on arbitrary lattices in arbitrary spatial dimensions. In the large $N$ limit, the higher dimensional model preserves many properties of the Sachdev-Ye-Kitaev model such as local criticality in two-point functions, zero temperature entropy and chaos measured by the out-of-time-ordered correlation functions. In addition, we obtain new properties unique to higher dimensions such as diffusive energy transport and a "butterfly velocity" describing the propagation of chaos in space. We mainly present results for a $(1+1)$-dimensional example, and discuss the general case near the end.

description: In this study, the two-dimensional (2D), lid-driven cavity flow of chiral liquid crystals (LCs) was modelled using the Landau de-Gennes (LdG) theory. Parametric studies investigating the effect of Er (Ericksen number) and Θ (chiral strength) on the microstructure of chiral LCs were performed. In this study, we observed that an increase in Θ caused the chiral texture to have more striations and shorter pitch lengths as causes for an increased number of defects. When Θ was held constant, an increase in Er disrupted the chiral structure and even broke it at very high Er. Interestingly, a transition from low Er (10) to moderate Er (1,000) increased the number of defects; however, further increases in Er reduced the number of defects since much of the chiral structure was destroyed by the high viscous flow effects. In particular, even at very high Er, the chiral structure and defects were still present as a vortex was always present with lower velocities, where the viscous flow effect was smaller. We also found that a hexagonal structure with penta-hepta defects formed at high chiral strengths.

description: Flat domain walls and spherical black holes are solutions to coupled second-order ODE's of the Hamiltonian form. Hamilton-Jacobi theory then implies that first-order flow equations always exist (possibly up to isolated submanifolds). If the first-order equations factorise in a specific way, they take a form that has been named fake supersymmetry. We point out that this factorisation is always possible at zero temperature. We therefore propose a less generic definition of fake supersymmetry, which involves the boundary conditions in a non-trivial way, and we analyse its physical relevance. For instance attractor flows are necessarily fake supersymmetric in our restricted sense. To illustrate the definition we provide new analytic solutions for axion-dilaton domain walls with fake superpotentials that were argued not to exist.

description: Electro-optic measurements reveal improved molecular ordering of ferroelectric liquid crystals (FLCs) by the presence of greener ternary CuGaS2/ZnS core/shell (CGZ) quantum dots (QDs). Experimental findings show that ternary CGZ QDs improve the anchoring of FLC which is validated by the increased primary- and secondary-order parameters (θ and Ps, respectively). The improved ordering of host FLCs is attributed to the enhanced localised charges by carrier trapping at intrinsic defect deep states in core assisted by reduced charge leakage probability, due to ZnS shell of CGZ QDs. The ternary CGZ QDs also improve photoluminescence and optical contrast of FLCs due to increase in molecular alignment. Helical nature of FLCs retained with incorporation of CGZ QDs was confirmed by pitch measurements. All these observations pointed out a way for better FLC-based display device.

description: Polymer dispersed liquid crystal (PDLC) films have potential applications in many aspects due to unique electrically switching properties, and thus the films with excellent comprehensive properties are highly demanded at present. In this study, aromatic polyurethane acrylate (PUA) was used as polymer-matrix, and effect of diluents [lauryl methacrylate (LMA) and isobornyl acrylate (IBOA)] content on the electrical-optical properties of PDLC films was investigated. The results indicate that increase of PUA/LMA or decrease of LMA/IBOA weight ratio increases threshold and saturation voltages (Vth and Vsat), decreases on- and off-state transmittances (Ton and Toff) and increases contrast ratio. Under optimised PUA/LMA weight ratio of 31/19 or PUA/LMA/IBOA weight ratio of 31/15/4, the Vth and Vsat of the films first increase and then decrease with increasing Ag nanowires (NWs) content, and better overall properties are achieved at 0.05 or 0.075 wt.% Ag NWs, respectively. In order to explore essential reasons for the influence of diluents and Ag NWs on the properties of PDLC films, the relationships between film properties (Vth or Vsat, Ton, Toff, and response time) and liquid crystal (LC) droplets size were analysed emphatically, and the changes of system viscosity and anchoring force between polymer-matrix and LC droplets were also discussed.
