description: This study presents a novel method for evaluating the scientific research papers in the field of assistive technologies pertaining to different impairment conditions. The objectives are to understand the technologies used for addressing the needs of PWD by identifying relevant criteria for the assessment, explore the implications of these technologies in their lives and identify the gaps among certain technologies in assisting PWD. In this article, we reviewed around 40 research scientific papers in relation to the technologies used to assist PWD in their daily activities. A novel quantitative assessment methodology based on Multi-weighted Scoring Model (MWSM) has been developed. It is based on the judgement of clinical experts according to thirteen well-defined criteria. The proposed method is useful because it assesses the scientific studies related to PWD qualitatively according to efficient research coverage, as well as quantitatively in order to have good comparative judgment. Moreover, this method recognizes the research gap or areas which need further investigation and identifies the research papers that have good coverage of the respective criteria.Implications for RehabilitationHuman computer interface (HCI) solutions are critical for addressing the main issues facing people with disabilities (PWD) in their life.Assessment of scientific research papers according to well-defined criteria that address PWD needs would assist in verifying their suitability for PWDs.Novel quantitative assessment methodology is used for assessing these research papers using judgment of experienced researchers according to 13 well-defined criteria that have been weighted according to relevancy to different impairment groups.Identifying research papers that have good coverage of defined criteria and knowing the research area that needs further investigation by researchers and developers, would ultimately address the rehabilitation needs for PWD.

description: Integrated thin-film lithium niobate platform has recently emerged as a promising candidate for next-generation, high-efficiency wavelength conversion systems that allow dense packaging and mass-production. Here we demonstrate efficient, phase-matched second harmonic generation in lithographically-defined thin-film lithium niobate waveguides with sub-micron dimensions. Both modal phase matching in fixed-width waveguides and quasi-phase matching in periodically grooved waveguides are theoretically proposed and experimentally demonstrated. Our low-loss (~ 3.0 dB/cm) nanowaveguides possess normalized conversion efficiencies as high as 41% W-1cm-2.

description: This paper describes the Bayesian Technique for Multi-image Analysis (BaTMAn), a novel image-segmentation technique based on Bayesian statistics that characterizes any astronomical dataset containing spatial information and performs a tessellation based on the measurements and errors provided as input. The algorithm iteratively merges spatial elements as long as they are statistically consistent with carrying the same information (i.e. identical signal within the errors). We illustrate its operation and performance with a set of test cases including both synthetic and real Integral-Field Spectroscopic data. The output segmentations adapt to the underlying spatial structure, regardless of its morphology and/or the statistical properties of the noise. The quality of the recovered signal represents an improvement with respect to the input, especially in regions with low signal-to-noise ratio. However, the algorithm may be sensitive to small-scale random fluctuations, and its performance in presence of spatial gradients is limited. Due to these effects, errors may be underestimated by as much as a factor of two. Our analysis reveals that the algorithm prioritizes conservation of all the statistically-significant information over noise reduction, and that the precise choice of the input data has a crucial impact on the results. Hence, the philosophy of BaTMAn is not to be used as a `black box' to improve the signal-to-noise ratio, but as a new approach to characterize spatially-resolved data prior to its analysis.

Security Aspects of Fuzzy Hashing

Publisher: name: Technische Universität Dortmund

Subjects: subject: 004

description: Hash functions are widely spread in computer science and used to map arbitrary large data to bit strings of a fixed length called a fingerprint. Cryptographic hash functions like SHA-1 or MD5 are established in various fields, but have one `drawback' due to several security requirements: if one bit of the input is changed, this results in a completely different fingerprint. In computer forensics cryptographic hashing represents the backbone in identifying files in sets of known-to-be-good (known as whitelisting) or known-to-be-bad files (known as blacklisting). Therefore, most investigators use hash databases, which are either created by themselves or maintained by institutions. Once they are in possession of such a database, the processing is straightforward: take a storage medium, compute all hash values, and perform look ups in the database. An active adversary, however, can destroy this straightforward proceeding by changing one bit of each file. Conditioned by the pseudo-randomness of the cryptographic hash function, this leads to completely different hash values. A 'similarity hash function' for files, i.e. a fuzzy-hashing function, would be the perfect counterpart for this attack. In 2006, Jesse Kornblum presented an implementation for this idea in [Kor06] named context triggered piecewise hashing (CTPH). Since then, he has been quoted numerous times (e.g. [Hur09]) and his approach has been improved with respect to performance (e.g. [SLC09]). However, there is no security analysis in terms of the reliability of the results. In our research, we address some security aspects of CTPH: 1. Even if two files have absolutely different content, we show how to efficiently achieve high match scores of the respective CTPH values of both files. This approach may be used to circumvent CTPH whitelisting. 2. We show how to efficiently manipulate a file by a fixed number of modification. The CTPH of the manipulated version of the file differs significantly from the CTPH of the original, although both versions are perceptually identical. This approach may be used to circumvent CTPH blacklisting. Besides these two anti-forensic issues, we also discovered weaknesses in the randomness of Kornblum's pseudo-random function. We showed how to improve Kornblum's pseudo-random function with respect to efficiency and randomness.

Phase transition kinetics and reorientational dynamics of the plastic crystal meta-carborane studied by deuteron NMR

Publisher: name: Elsevier Science
Year: 2002

description: Meta-carborane shows an orientationally disordered, orthorhombic phase which transforms into an ordered monoclinic phase near 170 K and into a quasi-isotropic cubic phase near 280 K. From deuteron magnetization measurements both transitions are found to exhibit a thermal hysteresis and slow transformation kinetics. Furthermore, solid-echo NMR spectra and spin-lattice relaxation times are reported. These results indicate that in the orthorhombic phase the meta-carborane molecules perform a strongly anisotropic motion which is characterized by a temperature dependent amplitude.

description: The dipolar relaxation dynamics of solid solutions of carbon dioxide and nitrous oxide has been investigated using dielectric spectroscopy. The temperature dependence of the relaxation rate reveals an ideal Arrhenius behavior for all concentrations, with energy barriers which scale linearly between the two pure compounds. The attempt frequencies are anomalously high. The distribution of relaxation times due to the static random fields as introduced by the substitutional impurity molecules is almost negligible. The melting temperature is determined by a critical relaxation rate of 40 kHz.

At last, I thought, a book that will increase art therapists clinical credence, scientifically researched evidence to give us knowledge and skills to underpin our understanding. My interest in clinical neuroscience spans many years, and I use this understanding to conceptualise meaning in the sometimes difficult to understand communications that the client/patient brings to the therapy room. On reading, I discover the various chapters give detailed theoretical understanding of brain regions, how neural pathways grow and connect, and how we might use this understanding to help our art therapy patients.

description: Particles moving inside a fluid near, and interacting with, invariant manifolds is a common phenomenon in a wide variety of applications. One elementary question is whether we can determine once a particle has entered a neighbourhood of an invariant manifold, when it leaves again. Here we approach this problem mathematically by introducing balance functions, which relate the entry and exit points of a particle by an integral variational formula. We define, study, and compare different natural choices for balance functions and conclude that an efficient compromise is to employ normal infinitesimal Lyapunov exponents. We apply our results to two different model flows: a regularized solid-body rotational flow and the asymmetric Kuhlmann--Muldoon model developed in the context of liquid bridges. Furthermore, we employ full numerical simulations of the Navier-Stokes equations of a two-way coupled particle in a shear--stress-driven cavity to test balance functions for a particle moving near an invariant wall. In conclusion, our theoretically-developed framework seems to be applicable to models as well as data to understand particle motion near invariant manifolds.
Possible Internal Structures and Compositions of Proxima Centauri b

description: We explore the possible Proxima Centauri b's interiors assuming the planet belongs to the class of dense solid planets (rocky with possible addition of water) and derive the corresponding radii. To do so, we use an internal structure model that computes the radius of the planet along with the locations of the different layers of materials, assuming that its mass and bulk composition are known. Lacking detailed elementary abundances of the host star to constrain the planet's composition, we base our model on solar system values. We restrained the simulations to the case of solid planets without massive atmospheres. With these assumptions, the possible radius of Proxima Centauri b spans the 0.94--1.40 $R_\oplus$ range. The minimum value is obtained considering a 1.10 $M_\oplus$ Mercury-like planet with a 65% core mass fraction, whereas the highest radius is reached for 1.46 $M_\oplus$ with 50% water in mass, constituting an ocean planet. Although this range of radii still allows very different planet compositions, it helps characterizing many aspects of Proxima Centauri b, such as the formation conditions of the system or the current amount of water on the planet. This work can also help ruling out future measurements of the planet's radius that would be physically incompatible with a solid planetary body.

description: While exact cloning of an unknown quantum state is prohibited by the linearity of quantum mechanics, approximate cloning is possible and has been used, e.g., to derive limits on the security of quantum communication protocols. In the case of asymmetric cloning, the information from the input state is distributed asymmetrically between the different output states. Here, we consider asymmetric phase-covariant cloning, where the goal is to optimally transfer the phase information from a single input qubit to different output qubits. We construct an optimal quantum cloning machine for two qubits that does not require ancilla qubits and implement it on an NMR quantum information processor.

description: What kind of protection is the Italian Constitution providing for the freedom of scientific research? Which are the limitations that can be put to the use of such freedom? These are the questions which this study tries to answer, taking as a starting point the reflection on how, in the past few years, scientific research has been able to deeply modify our lives allowing us to defeat once incurable diseases, at the same time, has forced us to question ourselves on the necessity to put limitations to the use of such freedom. Starting from an analysis of the historical origins of the constitutional rights given to scientific research, and a study of the related articles within the Italian Constitution, the attention was focused on the analysis of the limitations that legislative activities may put to the freedom of reserach. The main goal of this study is therefore to identify the evaluation criteria against which to assess the constitutionality of legislative action to restrict scientific research, also taking into consideration those instances in which the legislator requests the Public Administration the choice of the actual discipline related to this section.

description: We consider character correspondences between the characters of a group lying over a fixed character of a normal  subgroup, and a similar defined set of characters of a subgroup. This situation occurs in many applications, for example in the proof of important character correspondences found by Glauberman, Dade and Isaacs. With our methods we can give more transparent proofs of the results of Dade and Isaacs. We also consider rationality questions and generalizations to modular representation theory. We show that the Isaacs part of the Glauberman-Isaacs correspondence preserves Schur indices.
The pulse luminosity function of Swift gamma-ray bursts

description: The complete Swift Burst Alert Telescope and X-Ray Telescope light curves of 118 gamma-ray bursts (GRBs) with known redshifts were fitted using the physical model of GRB pulses by Willingale et al. to produce a total of 607 pulses. We compute the pulse luminosity function utilizing three GRB formation rate models: a progenitor that traces the cosmic star formation rate density (CSFRD) with either a single population of GRBs, coupled to various evolutionary parameters, or a bimodal population of high- and low-luminosity GRBs, and a direct fit to the GRB formation rate excluding any a priori assumptions. We find that a single population of GRB pulses with an evolving luminosity function is preferred over all other univariate evolving GRB models, or bimodal luminosity functions in reproducing the observed GRB pulse L-z distribution and that the magnitude of the evolution in brightness is consistent with studies that utilize only the brightest GRB pulses. We determine that the appearance of a GRB formation rate density evolution component is an artifact of poor parametrization of the CSFRD at high redshifts rather than indicating evolution in the formation rate of early epoch GRBs. We conclude that the single brightest region of a GRB light curve holds no special property, by incorporating pulse data from the totality of GRB emission we boost the GRB population statistics by a factor of 5, rule out some models utilized to explain deficiencies in GRB formation rate modelling, and constrain more tightly some of the observed parameters of GRB behaviour.

description: The thermodynamics of the molecular polaron model-a two-level system coupled to a harmonic oscillator-is studied. Close upper and lower bounds to the free energy are derived by means of Tchebycheff-Markov inequalities and are compared with the results of other authors. The 'nearly free' behaviour for high temperatures is confirmed. The self-trapping effects at low temperatures are weaker than predicted earlier. In contrast to the prediction of mean-field theory, the transition between the two temperature regimes is not a sharp phase transition but rather a smooth crossover.

description: We present a new nanoscale superconducting quantum interference device (SQUID) whose interference pattern can be shifted electrically in-situ. The device consists of a nanoscale four-terminal/four-junction SQUID fabricated at the apex of a sharp pipette using a self-aligned three-step deposition of Pb. In contrast to conventional two-terminal/two-junction SQUIDs that display optimal sensitivity when flux biased to about a quarter of the flux quantum, the additional terminals and junctions allow optimal sensitivity at arbitrary applied flux, thus eliminating the magnetic field "blind spots". We demonstrate spin sensitivity of 5 to 8 $μ_B/\text{Hz}^{1/2}$ over a continuous field range of 0 to 0.5 T, with promising applications for nanoscale scanning magnetic imaging.

description: The decay of single and double quantum coherences in amorphous ortho-terphenyl is studied by means of deuteron NMR echo experiments near and below the calorimetric glass transition temperature Tg. In perdeuterated samples a Gaussian decay for these coherences is found at low temperatures, in accord with theoretical predictions for random local dipolar fields. A method is proposed to extract information about slow motional processes from ordinary solid echo experiments below Tg. Partly deuterated ortho-terphenyl does not show a Gaussian decay. Simple model calculations show that this observation indicates the importance of correlations of the local dipolar fields in the presence of protons

description: While nuclear magnetic resonance (NMR) is one of the most important experimental tools for the analysis of bulk materials, the low sensitivity of conventional NMR makes it unsuitable for the investigation of small structures. We introduce an experimental scheme that makes NMR spectra of single, nanometer-sized quantum wells possible with excellent sensitivity and selectivity while avoiding the spectral broadening associated with some alternative techniques. The scheme combines optical pumping and pulsed radiofrequency excitation of the nuclei with time-resolved detection of the free induction decay through the polarization of the photoluminescence.

description: We utilize quantum superposition principle to establish the improvable upper and lower bounds on the stronger uncertainty relation, i.e., the "weighted-like" sum of the variances of observables. Our bounds include some free parameters which not only guarantee the nontrivial bounds but also can effectively control the bounds as tightly as one expects. Especially, these parameters don't obviously depend on the state and observables. It also implies one advantage of our method that any nontrivial bound can always be more improvable. In addition, we generalize both bounds to the uncertainty relation with multiple observables, but the perfect tightness is not changed. Examples are given to illustrate the improvability of our bounds in each case.

description: We present new results on [CII]158$μ$ m emission from four galaxies in the reionization epoch. These galaxies were previously confirmed to be at redshifts between 6.6 and 7.15 from the presence of the Ly$α$ emission line in their spectra. The Ly$α$ emission line is redshifted by 100-200 km/s compared to the systemic redshift given by the [CII] line. These velocity offsets are smaller than what is observed in z~3 Lyman break galaxies with similar UV luminosities and emission line properties. Smaller velocity shifts reduce the visibility of Ly$α$ and hence somewhat alleviate the need for a very neutral IGM at z~7 to explain the drop in the fraction of Ly$α$ emitters observed at this epoch. The galaxies show [CII] emission with L[CII]=0.6-1.6 x10$^8 L_\odot$: these luminosities place them consistently below the SFR-L[CII] relation observed for low redshift star forming and metal poor galaxies and also below z =5.5 Lyman break galaxies with similar star formation rates. We argue that previous undetections of [CII] in z~7 galaxies with similar or smaller star formation rates are due to selection effects: previous targets were mostly strong Ly$α$ emitters and therefore probably metal poor systems, while our galaxies are more representative of the general high redshift star forming population .

description: The open source ALPS (Algorithms and Libraries for Physics Simulations) project provides a collection of physics libraries and applications, with a focus on simulations of lattice models and strongly correlated systems. The libraries provide a convenient set of well-documented and reusable components for developing condensed matter physics simulation code, and the applications strive to make commonly used and proven computational algorithms available to a non-expert community. In this paper we present an updated and refactored version of the core ALPS libraries geared at the computational physics software development community, rewritten with focus on documentation, ease of installation, and software maintainability.

description: Introduction: The present study aims to characterize knowledge, attitudes and practices in a sample of occupational physicians (OPh) towards pertussis immunization in healthcare workers (HCWs). Material and Methods: A total of 148 OPh (45.9% males, mean age of 40.3±13.2 years) compiled a web questionnaire including a knowledge test on Italian recommendations for HCWs, epidemiology and pathology of pertussis infection, being then investigated about risk perceptions and vaccination practices. A General Knowledge Score (GKS) and a Risk Perception Score (RPS) were calculated. Multivariate odds ratios (OR) for predictors of vaccine propensity were calculated through regression analysis. Results: 78 participants regularly recalled pertussis vaccination status and/or performed pertussis vaccination in HCWs (52.7%). Proactive status was correlated with the aim to avoid pertussis infection in HCWs and its diffusion to other adults (p < 0.001, both statements). GKS was satisfying (72.4%±14.9), but participants underestimated the clinical issues of pertussis infection (RPS 60.8%±9.5) when confronted with influenza (73.9%±10.9) and HBV infection (68.1%±10.1). GKS and RPS were well correlated (r = 0.244, p = 0.003). Eventually, a better GKS and the aim to avoid pertussis infection in HCWs were predictive of a proactive status for pertussis vaccination (OR 4.186 95%CI 1.809–9.685 and OR 11.459, 95%CI 3.312–39.651, respectively). Conclusions: Adherence of OPh to HCWs pertussis vaccination was unsatisfying. As knowledge status was predictive for vaccine propensity, information programs for OPh should be more appropriately designed, stressing that HCWs may represent a significant reservoir for pertussis infection in high risk groups (e.g. children/newborns, frail elderly).

description: Proton, deuteron, and carbon NMR methods were applied to study various isotopic species of supercooled and glassy propylene carbonate. The molecular diffusion was investigated via static field gradient diffusometry and yielded evidence for a particularly pronounced enhancement of the translational over the reorientational dynamics. The latter was monitored using measurements of spin-lattice relaxation times and of two-time stimulated echoes. The sin–sin correlation functions exhibited a pronounced dependence on the evolution times. From these results it is concluded that the geometry of molecular reorientation can be described as a superposition of moderately small jump angles (about 30°) and a quasi-diffusive component which is responsible for about one-third of the total angular displacement. Finally, four-time stimulated echoes confirmed that the nonexponential relaxation in propylene carbonate is dynamically heterogeneous in nature.

description: The stability of iterations of affine linear maps $Ψ_{n}(x)=A_{n}x+B_{n}$, $n=1,2,\ldots$, is studied in the presence of a Markovian environment, more precisely, for the situation when $(A_{n},B_{n})_{n\ge 1}$ is modulated by an ergodic Markov chain $(M_{n})_{n\ge 0}$ with countable state space $\mathcal{S}$ and stationary distribution $π$. We provide necessary and sufficient conditions for the a.s. and the distributional convergence of the backward iterations $Ψ_{1}\circ\ldots\circΨ_{n}(Z_{0})$ and also describe all possible limit laws as solutions to a certain Markovian stochastic fixed-point equation. As a consequence of the random environment, these limit laws are stochastic kernels from $\mathcal{S}$ to $\mathbb{R}$ rather than distributions on $\mathbb{R}$, thus reflecting their dependence on where the driving chain is started. We give also necessary and sufficient conditions for the distributional convergence of the forward iterations $Ψ_{n}\circ\ldots\circΨ_{1}$. The main differences caused by the Markovian environment as opposed to the extensively studied case of independent and identically distributed (iid) $Ψ_{1},Ψ_{2},\ldots$ are that: (1) backward iterations may still converge in distribution, if a.s. convergence fails, (2) the degenerate case when $A_{1}c_{M_{1}}+B_{1}=c_{M_{0}}$ a.s. for suitable constants $c_{i}$, $i\in\mathcal{S}$, is by far more complex than the degenerate case for iid $(A_{n},B_{n})$ when $A_{1}c+B_{1}=c$ a.s. for some $c\in\mathbb{R}$, and (3) forward and backward iterations generally have different laws given $M_{0}=i$ for $i\in\mathcal{S}$ so that the former ones need a separate analysis. Our proofs draw on related results for the iid-case, notably by Vervaat, Grincevičius, and Goldie and Maller, in combination with recent results by the authors on fluctuation theory for Markov random walks.

description: Abstract Data-driven research is growing exponentially. In order to support researchers with the sustainable management of their data, research institutions – libraries in particular – increasingly hire staff for an array of data-related roles. The position of data stewards has become prevalent in recent years – especially in Europe. Data stewards need specialized training in addition to their degree(s) in a scientific discipline. According to Barend Mons, 500,000 data stewards will need to be trained in the EU alone (1). Such options are increasingly being offered internationally and range from short training courses to whole master’s degrees. The first professional data stewards in Austria (such as at the Graz University of Technology) had to acquire their skills and knowledge on the job (2). In 2021, the Vienna University Library developed the first certificate course for data stewards in Austria, to support national and international efforts regarding Open Science education and training. With regard to the tasks of data stewards – such as the support of researchers, knowledge transfer, research data management (RDM) training and requirements engineering (3) – as well as recommendations for data stewardship competencies, the course includes various aspects of RDM and Open Science, as well as the basics of data science and programming. The course builds upon the most successful parts of the certificate course “Data Librarian” which was offered by the Vienna University Library together with three other Austrian libraries in the years 2018-2021 as well as similar programmes from other countries. The course is practice-oriented and allows the participants to learn not only from national and international experts on data stewardship and RDM, but also benefit from transdisciplinary exchange amongst themselves. The part-time programme is offered in a hybrid format as a way for RPOs to upskill current research support staff as well as offer an alternative career path for researchers. The first round started in October 2022 with 25 participants from ten countries and will finish in June 2023. Research institutions worldwide are developing training courses to meet the growing demand to professionalize data stewardship education. As the first formalized further education programme in Austria, this presentation on the certificate course “Data Steward” from the Vienna University Library is sure to spark discussion on the topic of data stewardship training and contribute to the global efforts regarding Open Science education. The lessons learned throughout the development and the first round of the course should serve as an example of possible collaborative efforts to implement high-quality certified data stewardship training on the national level.
