description: Molecular matter-wave interferometry enables novel strategies for manipulating the internal mechanical motion of complex molecules. Here, we show how chiral molecules can be prepared in a quantum superposition of two enantiomers by far-field matter-wave diffraction and how the resulting tunnelling dynamics can be observed. We determine the impact of ro-vibrational phase averaging and propose a setup for sensing enantiomer-dependent forces, parity-violating weak interactions, and environment-induced superselection of handedness, as suggested to resolve Hund's paradox. Using ab-initio tunnelling calculations, we identify [4]-helicene derivatives as promising candidates to implement the proposal with state-of-the-art techniques. This work opens the door for quantum sensing and metrology with chiral molecules.

description: Quantum phase transition is one of the main interests in the field of condensed matter physics, while geometric phase is a fundamental concept and has attracted considerable interest in the field of quantum mechanics. However, no relevant relation was recognized before recent work. In this paper, we present a review of the connection recently established between these two interesting fields: investigations in the geometric phase of the many-body systems have revealed so-called "criticality of geometric phase", in which geometric phase associated with the many-body ground state exhibits universality, or scaling behavior in the vicinity of the critical point. In addition, we address the recent advances on the connection of some other geometric quantities and quantum phase transitions. The closed relation recently recognized between quantum phase transitions and some of geometric quantities may open attractive avenues and fruitful dialog between different scientific communities.

Operationalizing the Theory of Human Values: Balancing Homogeneity of Reflective Items and Theoretical Coverage

Subjects: Human values; Portrait Values Questionnaire; composite scores; validity; CFA

description: Schwartz's theory of human values, as operationalized using different instruments such as the Portrait Values Questionnaire (PVQ), was confirmed by multiple studies using Smallest Space Analysis (SSA). Because of its success, a short version of the PVQ was introduced in the European Social Survey (ESS). However, initial tests using Confirmatory Factor Analysis (CFA) pointed to low discriminant validity of the 10 basic values: The correlations between values next to each other in the two-dimensional space described by SSA were close to or greater than 1. In response, one research stream suggested combining the factors with low discriminant validity. Another stream suggested that the problem was not low discriminant validity but rather misspecifications in the model. Analyses of the short Portrait Values Questionnaire of the ESS confirmed the latter view.
This paper demonstrates that the problems of the short version of the PVQ exist in the full 40-item PVQ as well. Based on SEM analyses of the items of the full PVQ, we propose that it can provide measures of 15 more narrowly defined values with good discriminant validity. Our proposal respects the conceptual complexity of the values theory while avoiding contamination of composite scores. It can be expected that the improved measurement of 15 values will increase their predictive power. The presence of some single items suggests the extension of the value theory and scales to encompass more than 15 values. Implications for further development of the scale are drawn.

description: String sorting is an important part of tasks such as building index data structures. Unfortunately, current string sorting algorithms do not scale to massively parallel distributed-memory machines since they either have latency (at least) proportional to the number of processors p or communicate the data a large number of times (at least logarithmic). We present practical and efficient algorithms for distributed-memory string sorting that scale to large p. Similar to state-of-the-art sorters for atomic objects, the algorithms have latency of about p^{1/k} when allowing the data to be communicated k times. Experiments indicate good scaling behavior on a wide range of inputs on up to 49152 cores. Overall, we achieve speedups of up to 4.9 over the current state-of-the-art distributed string sorting algorithms.

Constraints on right handed insertions, in particular, improve considerably in the large $\tanb$ regime where the contributions to $B_s$ mixing are dominated by double Higgs penguins. Similarly, the allowed regions of parameter space when varying multiple insertions also decrease significantly.

description: High-energy astrophysical neutrino fluxes are, for many applications, modeled as simple power laws as a function of energy. While this is reasonable in the case of neutrino production in hadronuclear $pp$ sources, it typically does not capture the behavior in photohadronic $pγ$ sources: in that case, the neutrino spectrum depends on the properties of the target photons the cosmic rays collide with and on possible magnetic-field effects on the secondary pions and muons. We show that the neutrino production from known photohadronic sources can be reproduced by a thermal (black-body) target-photon spectrum if one suitably adjusts the temperature, thanks to multi-pion production processes. This allows discussing neutrino production from most known $pγ$ sources, such as gamma-ray bursts, active galactic nuclei and tidal disruption events, in terms of a few parameters. We apply this thermal model to study the sensitivity of different classes of neutrino telescopes to photohadronic sources: we classify the model parameter space according to which experiment is most suitable for detection of a specific source class and demonstrate that different experiment classes, such as dense arrays, conventional neutrino telescopes, or radio-detection experiments, cover different parts of the parameter space. Since the model can also reproduce the flavor and neutrino-antineutrino composition, we study the impact on the track-to-shower ratio and the Glashow resonance.

Measurement invariance and quality of composite scores in a face-to-face and a web survey

Subjects: measurement equivalence; composite scores; modes of data collection

description: Measurement equivalence is a pre-requisite to be able to make comparisons across groups. In this paper we are interested in testing measurement equivalence across respondents answering surveys done using different modes of data collection. Indeed, different modes of data collection have specific characteristics that may create measurement non-equivalence across modes. If this is so, data collected in different modes cannot be compared. This would be problematic since, in order to respond to new challenges, like costs and time pressure, more and more often researchers choose to use different modes to collect their data across time, across surveys, and across countries. Studying data about trust and attitudes towards immigration, this paper shows that measurement equivalence holds across a face-to-face and a web survey done in the Netherlands (2008-2009). Moreover, the quality estimates of the Composite Scores are quite high and pretty similar in the two surveys for the four concepts considered.

description: The question which is the most preferred type of documentary between linear and non - linear is discussed in the present study. In order to find out which is the preferred type we have created two documentaries one conventional and one interactive on same topic and we have presented them into two focus groups. The two focus groups reflected the viewing habits of digital natives who are people around the age of 18-25 and digital immigrants who are people above the age of 37. In this dissertation we clarify the viewing habits of the participants of both focus groups. With their answers, digital natives and digital immigrants, redefine the advantages and disadvantages of interactive video. Their responses give a clear precedence to conventional documentary due to the cinematic experience that it offers. Among the viewing habits of digital natives great importance is given into second screening and the on demand viewing. An important outcome of this research is the dispute of the advantages of interactive documentary

We show how to do decoy-state quantum key distribution efficiently with large random errors in the intensity control. In our protocol, the linear terms of fluctuation disappear and only the quadratic terms take effect. We then show the unconditional security of decoy-state method with whatever error pattern in intensities of decoy pulses and signal pulses provided that the intensity of each decoy pulse is less than $μ$ and the intensity of each signal pulse is larger than $μ'$.

description: In this work we show that Einstein gravity in four dimensions can be consistently obtained from the compactification of a generic higher curvature Lovelock theory in dimension $D=4+p$, being $p\geq1$. The compactification is performed on a direct product space $\mathcal{M}_D=\mathcal{M}_4\times\mathcal{K}^p$, where $\mathcal{K}^p$ is a Euclidean internal manifold of constant curvature. The process is carried out in such a way that no fine tuning between the coupling constants is needed. The compactification requires to dress the internal manifold with the flux of suitable $p$-forms whose field strengths are proportional to the volume form of the internal space. We explicitly compactify Einstein-Gauss-Bonnet theory from dimension six to Einstein theory in dimension four and sketch out a similar procedure for this compactification to take place starting from dimension five. Several black string/p-branes solutions are constructed, among which, a five dimensional asymptotically flat black string composed of a Schwarzschild black hole on the brane is particularly interesting. Finally, the thermodynamic of the solutions is described and we find that the consistent compactification modifies the entropy by including a constant term, which may induce a departure from the usual behavior of the Hawking-Page phase transition. New scenarios are possible in which large black holes dominate the canonical ensamble for all temperatures above the minimal value.

Informed Consent for Web Paradata Use

Subjects: paradata; web surveys; informed consent

description: Survey researchers are making increasing use of paradata - such as keystrokes, clicks, and timestamps - to evaluate and improve survey instruments but also to understand respondents and how they answer surveys. Since the introduction of paradata, researchers have been asking whether and how respondents should be informed about the capture and use of their paradata while completing a survey. In a series of three vignette-based experiments, we examine alternative ways of informing respondents about capture of paradata and seeking consent for their use. In all three experiments, any mention of paradata lowers stated willingness to participate in the hypothetical surveys. Even the condition where respondents were asked to consent to the use of paradata at the end of an actual survey resulted in a significant proportion declining. Our research shows that requiring such explicit consent may reduce survey participation without adequately informing survey respondents about what paradata are and why they are being used.

Subjects: volunteer panel; self-selection; propensity weighting; calibration; variance estimation

description: Household and individual surveys increasingly gain importance in policy support and other areas. However, the raising number of surveys leads to reduced response rates. One way to overcome the problem of nonparticipation in surveys involving a non-response bias is to use access panels as a sampling frame. Though leading to expected higher response rates, the self-selection process at the recruitment stage urges the need for a bias correction. This can be done directly when extrapolating the estimates to the population of interest or when using response propensity scores. The latter implies a correct model specification on the recruitment stage.

description: Abstract

Background: Diabetes mellitus (DM) is a chronic disorder with persistently elevated blood glucose levels that leads to the development of microvascular and macrovascular complications over several years. The bidirectional relationship between DM and the lungs is clinically proven to have progressive pulmonary function abnormalities with decreased Forced Expiratory Volume in 1 second (FEV1) and Forced Vital Capacity (FVC) in individuals with poor DM control. Methods: This study was an observational analytic study using a Case Control approach method in patients with Diabetes Mellitus at Pangkajene Health Center. Each research subject underwent spirometry examination. Results: This study involved 133 research subjects, consisting of 3 groups, uncontrolled diabetes mellitus patients 38.2%, controlled 36.6%, and control group 25.2%. The mean age was 60.13 ± 9.82, 40 males and 91 females. The mean HbA1c value was 8.55 ± 1.69. Spirometric examinations were performed on all groups with parameters of Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), and FEV1/FVC ratio. The mean Forced Vital Capacity (FVC) value in all samples was 73.65%, the mean Forced Expiratory Volume in the first second (FEV1) value was 60.47%, and the mean FEV1/FVC value was 86.25%. Conclusion: There was a significant weak negative correlation between HbA1c and FVC and FEV1 in uncontrolled DM patients. This indicates that the higher the HbA1c value, the lower the FVC and FEV1 values will be.

description: This cumulative dissertation introduces new methods of the topic of entanglement testing based on the separability eigenvalue equations. In principle, the separability eigenvalue equations represent a method to construct entanglement tests via witnessing approaches. An approach is presented that enables finding reliable entanglement tests even for experimental states. A newly introduced algorithm, the Separability Power Iteration, enables finding solutions to the separability eigenvalue equations numerically, thereby broadening the range on the introduced approach.
Consent when Linking Survey Data with Administrative Records: The Role of the Interviewer
Creators: name: Korbmacher, Julie M.
name: Schroeder, Mathis
Publisher: name: European Survey Research Association
Year: 2013
Subjects: record linkage; interviewers

description: Linking survey data with administrative records is becoming more common in the social sciences in recent years. Regulatory frameworks require the respondent's consent to this procedure in most cases. Similar to non-response, non-consent may lead to selective samples and could pose a problem when using the combined data for analyses. Thus investigating the selectivity and the determinants of the consent decision is important in order to find ways to reduce non-consent.
Adapting the survey participation model by Groves and Couper (1998), this paper identifies different areas influencing the respondents' willingness to consent. In addition to control variables at the individual and household level, two further areas of interest are included: the interview situation and the characteristics of the interviewer. A multilevel approach highlights the importance of the interviewer for the consent decision: the empty model shows an intra-class correlation of 55%, which can be reduced to 35% in a full model including interviewer variables. An additional analysis including measures of interviewer performance shows that there are further unobserved interviewer characteristics that influence the respondent's consent decision.
The results suggest that although respondent and household characteristics are important for the consent decision, a large part of the variation in the data is explained by the interviewers. This finding stresses the importance of the interviewers not only as an integral part in data collection efforts, but also as the direct link to gain a respondent's consent for linking survey data with administrative records.

description: Device-independent quantum key distribution is a secure quantum cryptographic paradigm that allows two honest users to establish a secret key, while putting minimal trust in their devices. Most of the existing protocols have the following structure: first, a bipartite nonlocal quantum state is distributed between the honest users, who perform local measurements to establish nonlocal correlations. Then, they announce the implemented measurements and extract a secure key by post-processing their measurement outcomes. We show that no protocol of this form allows for establishing a secret key when implemented on any correlation obtained by measuring local projective measurements on certain entangled nonlocal states, namely on a range of entangled two-qubit Werner states. To prove this result, we introduce a technique for upper-bounding the asymptotic key rate of device-independent quantum key distribution protocols, based on a simple eavesdropping attack. Our results imply that either different reconciliation techniques are needed for device-independent quantum key distribution in the large-noise regime, or Bell nonlocality is not sufficient for this task.

description: The Cryogenic Dark Matter Search (CDMS) and XENON experiments aim to directly detect dark matter in the form of weakly interacting massive particles (WIMPs) via their elastic scattering on the target nuclei. The experiments use different techniques to suppress background event rates to the minimum, and at the same time, to achieve a high WIMP detection rate. The operation of cryogenic Ge and Si crystals of the CDMS-II experiment in the Soudan mine yielded the most stringent spin-independent WIMP-nucleon cross-section (~10^{-43} cm^2) at a WIMP mass of 60 GeV/c^2. The two-phase xenon detector of the XENON10 experiment is currently taking data in the Gran Sasso underground lab and promising preliminary results were recently reported. Both experiments are expected to increase their WIMP sensitivity by a one order of magnitude in the scheduled science runs for 2007.

description: Today we have quite stringent constraints on possible violations of the Weak Equivalence Principle from the comparison of the acceleration of test-bodies of different composition in Earth's gravitational field. In the present paper, we propose a test of the Weak Equivalence Principle in the strong gravitational field of black holes. We construct a relativistic reflection model in which either the massive particles of the gas of the accretion disk or the photons emitted by the disk may not follow the geodesics of the spacetime. We employ our model to analyze the reflection features of a NuSTAR spectrum of the black hole binary EXO 1846-031 and we constrain two parameters that quantify a possible violation of the Weak Equivalence Principle by massive particles and X-ray photons, respectively.

description: In 2004 Germany's Federal Statistical Office (Statistisches   Bundesamt, Destatis) started the recruitment of an access panel (AP) from participantes in the German microcensus (MC), a large household survey. This access panel, a pool of persons willing to take part in voluntary surveys, currently serves as the sampling frame for the DE-SILC, the German subsample of the European Union Statistic on Income and Living Conditions. Sampling from panelists rather than directly from the population promised lower survey costs due to easy access to the AP participants and higher response rates. While participation in the MC is mandatory by law, joining the AP is voluntary. Approx. 10 percent of the MC households agree to enter the panel. In this work we examine the recruitment from the 2006 MC using socio-economic and demographic characteristics available in both the AP and the MC to explore the selectivity of the recruitment process. We also discuss the implications of German privacy protection legislation for this analysis. Finally we consider the longitudinal use of the AP in a methodological discussion on the question whether samples from the AP can be regarded as probability samples from the general population.

Glued-in re-bar connection
Creators: name: Malczyk, Robert
Publisher: name: University of British Columbia
Year: 2008

description: The aim of this research was to develop a reliable structural timber connection, which would break by failure of its steel components, thus taking advantage of the lower variability and higher strength of steel. The basic concept of the joint was to glue the reinforcing bars in pre-drilled holes and develop a bond strength stronger than tensile resistance of the bar. This report describes the testing and design of such connections. The joints consist of re-bars and steel plates. Weldable #10 and #20 re-bars were used. The steel plates were cut from flat bar. The re-bars are welded to the steel plates and inserted into the holes, and fixed to the wood by epoxy glue. The holes are drilled on an angle to the grain; 30 degree angle was found to be the most effective. The testing consisted of preliminary pull-out tests used to establish the embedment length needed to induce steel failures. Additional testing examined the behavior of glued-in rod joints used as a beam splice connection, a column foundation joint loaded with horizontal forces, and knee joints as used in a portal frame, loaded with positive and negative moment. Steel failures were observed consistently. A typical portal frame was designed in order to tie the research to practical applications. Internal forces from this analysis were then used as a guide to the magnitude of the forces that can be expected in real life situations. In the last part of this report the necessary design steps for two configurations of glued-in rod joints are presented: 1.Column foundation or beam splice joints. 2.Knee joints. This was performed in order to inform structural engineers how glued-in rod joints work under load, and how they should be designed. Glued-in rod connections have several advantages over presently used systems. They can be manufactured in the glulam plant, using conventional tools, reducing the field work to merely bolting of the joints. The construction method becomes very similar to the erection methods of the steel structures. The elements are connected by bolts or welding. Glued-in rod connections have a great potential to become a safe connection method for the statically indetermined structures. The testing of knee joints showed the possibility of developing a moment resisting connection, which would make glulam more competitive against steel in the area of portal frames widely used for commercial buildings.

The experiment was performed at the ($e^+$ $e^-$) collider DA$Φ$NE at Laboratori Nazionale di Frascati of INFN. It is the first measurement for $\mathrm{^7_ΛLi}$, and for all the spectra the lower limit on the energy of the protons is 15 MeV, never reached before. All the spectra show a similar shape, namely a peak at around 80 MeV as expected for the free $Λp \to np$ weak reaction, with a low energy rise that should be due to Final State Interactions and/or two--nucleon induced weak processes. The decay spectrum of $\mathrm{^5_ΛHe}$ is somehow similar to the ones reported by previous measurements and theoretical calculations, but the same doesn't happen for the $\mathrm{^{12}_ΛC}$ one.

description: Quantum computing can become scalable through error correction, but logical error rates only decrease with system size when physical errors are sufficiently uncorrelated. During computation, unused high energy levels of the qubits can become excited, creating leakage states that are long-lived and mobile. Particularly for superconducting transmon qubits, this leakage opens a path to errors that are correlated in space and time. Here, we report a reset protocol that returns a qubit to the ground state from all relevant higher level states. We test its performance with the bit-flip stabilizer code, a simplified version of the surface code for quantum error correction. We investigate the accumulation and dynamics of leakage during error correction. Using this protocol, we find lower rates of logical errors and an improved scaling and stability of error suppression with increasing qubit number. This demonstration provides a key step on the path towards scalable quantum computing.
Liquid crystals in two dimensions: First-order phase transitions and nonuniversal critical behavior
Creators: name: Vink, R. L. C.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Liquid crystals in two dimensions undergo a first-order isotropic-to-quasi-nematic transition, provided the particle interactions are sufficiently ``sharp and narrow''. This implies phase coexistence between isotropic and quasi-nematic domains, separated by interfaces. The corresponding line tension is determined, and shown to be very small, giving rise to strong interface fluctuations. When the interactions are no longer ``sharp and narrow'', the transition becomes continuous, with non-universal critical behavior obeying hyperscaling, and approximately resembling the two-dimensional Potts model.

'How long will it take?' An analysis of interview length in the fifth round of the European Social Survey
Creators: name: Loosveldt, Geert

Publisher: name: European Survey Research Association
Year: 2013
Subjects: Interview length; interviewer effects; European Social Survey

description: The question ‘How long will the interview take?’ is frequently asked by interviewers during training and by respondents during the initial doorstep interaction. In this paper, we investigate the impact of different interviewers, countries and some respondent characteristics on interview length in the fifth round of the European Social Survey.
The results show substantial differences between countries with regard to interview length and reinforce that differences between countries are based on much more than just the differences between languages. The results support the obvious suggestion that fewer applicable questions reduce the interview length. Further, interviewing older respondents takes more time, and the duration also increases if a respondent more frequently asks for clarification. The huge impact of interviewers on interview length is the most remarkable result. In all countries, the difference between interviewers accounts for a significant and substantial part of the variance in interview length. More detailed fieldwork monitoring in each country is necessary in order to understand these differences. The results also clearly illustrate the necessity for investment in training, monitoring and follow-up of interviewers in each country participating in a cross-national survey.

LADMM-Net: An Unrolled Deep Network For Spectral Image Fusion From Compressive Data

description: Image fusion aims at estimating a high-resolution spectral image from a low-spatial-resolution hyperspectral image and a low-spectral-resolution multispectral image. In this regard, compressive spectral imaging (CSI) has emerged as an acquisition framework that captures the relevant information of spectral images using a reduced number of measurements. Recently, various image fusion methods from CSI measurements have been proposed. However, these methods exhibit high running times and face the challenging task of choosing sparsity-inducing bases. In this paper, a deep network under the algorithm unrolling approach is proposed for fusing spectral images from compressive measurements. This architecture, dubbed LADMM-Net, casts each iteration of a linearized version of the alternating direction method of multipliers into a processing layer whose concatenation deploys a deep network. The linearized approach enables obtaining fusion estimates without resorting to costly matrix inversions. Furthermore, this approach exploits the benefits of learnable transforms to estimate the image details included in both the auxiliary variable and the Lagrange multiplier. Finally, the performance of the proposed technique is evaluated on two spectral image databases and one dataset captured at the laboratory. Extensive simulations show that the proposed method outperforms the state-of-the-art approaches that fuse spectral images from compressive measurements.

description: Η παρούσα έρευνα επιδιώκει την διερεύνηση της κατανόησης των φυσικών εννοιών και πιο συγκεκριμένα την έννοια της τριβής από τους μαθητές της Στ’ τάξης των δύο δημοτικών σχολείων στον νομό Άρτας. Για την πραγματοποίηση της έρευνας συγκροτήθηκαν δύο διδακτικές παρεμβάσεις για την έννοια της τριβής βασισμένες στην εποικοδομητική προσέγγιση της μάθησης βασισμένη σε επιστημονικές πρακτικές. Οι διδακτικές παρεμβάσεις που σχεδιάστηκαν πραγματοποιήθηκαν σε δύο διαφορετικά τμήματα στο νομό Άρτας σε μαθητές της Στ’τάξης του δημοτικού. Πιο συγκεκριμένα οι μαθητές του δημοτικού σχολείου Γραμμενίτσας που υπάγεται στο νομό Άρτας διδάχθηκαν την έννοια της τριβής μέσω πειραματικών δραστηριοτήτων κάνοντας χρήση το εκπαιδευτικό κιτ ρομποτικής της LEGO WeDo 2.0 Core ενώ οι μαθητές του 2ου Δημοτικού σχολείου Άρτας έκαναν χρήση το εκπαιδευτικό λογισμικό προσομοιώσεων Algodoo. Για την αξιολόγηση των μαθησιακών αποτελεσμάτων οι μαθητές συμπλήρωσαν το ερωτηματολόγιο που λειτούργησε ως pre και post test. Μετά την εφαρμογή των παρεμβάσεων η ανάλυση των δεδομένων έδειξε ότι οι δύο διαφορετικές διδακτικές παρεμβάσεις συνέβαλαν με θετικό τρόπο στην τροποποίηση των αντιλήψεων των μαθητών. Αξιολογώντας τις απαντήσεις των μαθητών στα τελικά ερωτηματολόγια συμπεραίνεται ότι η θετική επίδραση της ρομποτικής ήταν αρκετά μεγαλύτερη σχετικά με την θετική επίδραση του λογισμικού
description: The present study investigates the understanding of science concepts and, particularly, the perception of friction by students of the sixth grade in two elementary schools in the regional unit of Arta, Greece. Two teaching interventions were developed for the concept of friction based on a constructive approach using modern scientific practices. The proposed interventions were carried out in two different schools. The first intervention includes experimental activities using the LEGO WeDo 2.0 Core robotic kit and was conducted in the elementary school of Grammenitsa. The second intervention is based on the Algodoo simulation training software and was conducted in the 2nd Elementary School of Arta. The evaluation of the learning outcomes was performed through questionnaire completed by the students both before and after the teaching interventions. Αfter the two teaching interventions it was noticed that the understanding of the students of both the two different schools was improved. Based on the data collected from the two different interventions, it is concluded that the intervention with the educational robotic kit was more efficient compared to the one with the simulation training software

description: We investigate the in-medium interparticle potential of hot gauge system with bound states by employing the QED and scalar QED coupling. At finite temperature an oscillatory behavior of the potential has been found as well as its variation in terms of different free parameters. We expect the competition among the parameters will lead to an appropriate interparticle potential which could be extended to discuss the fluid properties of QGP with scalar bound states.
