description: Bose-Einstein condensate (BEC)-based atom interferometry exploits low temperatures and long coherence lengths to facilitate high-precision measurements. Progress in atom interferometry promises improvements in navigational devices like gyroscopes and accelerometers, as well as applications in fundamental physics such as accurate determination of physical constants. Previous work demonstrates that beam splitters and mirrors for coherent manipulation of dilute BEC momentum in atom interferometers can be implemented with sequences of non-resonant standing-wave light pulses. While previous work focuses on the optimization of the optical pulses' amplitude and duration to produce high-order momentum states with high fidelity, we explore how varying the shape of the optical pulses affects optimal beam-splitter performance, as well as the effect of pulse shape on the sensitivity of optimized parameters in achieving high fidelity in high-momentum states. In simulations of two-pulse beam splitters utilizing optimized square, triangle, and sinc-squared pulse shapes applied to dilute BECs, we, in some cases, reduce parameter sensitivity by an order of magnitude while maintaining fidelity.

description: This research article introduces a novel family of distributions achieved through the methodology of the π-power transformation technique. The study focuses on one specific member that is inverse Weibull distribution within this family, which showcases a hazard function exhibiting distinct J, reverse-J, bathtub, or monotonically increasing shapes. The article explores the essential characteristics of this distribution and employs the maximum likelihood estimation (MLE) method to estimate its associated parameters. To evaluate the accuracy of the estimation procedure, a simulation experiment is conducted, revealing a decrease in biases and mean square errors as sample sizes increase, even when working with small samples. Furthermore, the practical application of the proposed distribution is demonstrated by analyzing two real medical and traffic datasets. By employing model selection criteria and conducting goodness-of-fit test statistics, the article establishes that the proposed model surpasses existing models in performance. The application of this research work can be significant in various fields where modeling and analyzing hazard functions or survival data are essential, while also making contributions to probability theory and statistical inferences.

description: We study by computer simulation the "Hawkes process" that was proposed in a recent paper by Crane and Sornette (Proc. Nat. Acad. Sci. USA 105, 15649 (2008)) as a plausible model for the dynamics of YouTube video viewing numbers. We test the claims made there that robust identification is possible for classes of dynamic response following activity bursts. Our simulated timeseries for the Hawkes process indeed fall into the different categories predicted by Crane and Sornette. However the Hawkes process gives a much narrower spread of decay exponents than the YouTube data, suggesting limits to the universality of the Hawkes-based analysis.

description: Partial atomic charges are a useful and intuitive concept for understanding molecular properties and chemical reaction mechanisms, showing how changes in molecular geometry can affect the flow of electronic charge within a molecule. However, the use of partial atomic charges remains relatively uncommon in the characterization of excited-state electronic structure. Here we show how well-established partial atomic charge methods perform for interatomic, intermolecular and inter-bond electron transfer in electronically excited states. Our results demonstrate the utility of real-space partial atomic charges for interpreting the electronic structures that arise in excited-state processes. Furthermore, we show how this analysis can be used to demonstrate that analogous electronic structures arise near photochemically relevant conical intersection regions for several conjugated polyenes. Based on our analysis, we find that charges computed using the iterative Hirshfeld approach provide results which are consistent with chemical intuition and are transferable between homologous molecular systems.

description: Purpose: To investigate the influence of abutment material properties on the fracture resistance and failure mode of lithium disilicate (IPS e.max) CAD/CAM (computer-aided design/manufacturing) crowns on traditionally and minimally prepared simulated tooth substrates. Materials and Methods: Sixty lithium disilicate (IPS e.max) CAD/CAM crowns were divided into three groups (n=20): TD: traditional thickness crowns cemented on Paradigm MZ100 abutments; MD: minimal thickness crowns cemented on Paradigm MZ100 abutments; ME: minimal thickness crowns cemented on e.max abutments. The 3Shape system was used to scan, design and mill all abutments and crowns with a die space set to 40 micrometers. Traditional thickness crowns were designed based on manufacturer guidelines with 1.5mm occlusal thickness and 1.0mm margins. Minimal thickness crowns were designed with 0.7mm occlusal thickness and 0.5mm margins. MZ100 composite and e.max abutments were selected to simulate dentin and enamel substrates respectively based on their elastic-modulus. Variolink Esthetic was used to cement all samples following manufacturer’s instructions. Half the specimens in each group were stored in water for 7 days before fracture load was tested. The other half were stored in water for 120 days with 37,500 thermocycles from 5ºC and 55ºC. A universal testing machine was used to load all specimens to fracture with a 3mm radius stainless steel hemispherical tip at a crosshead speed 0.5mm/minute along the longitudinal axis of the abutment with a 1mm thermoplastic film placed between the loading tip and crown surface. Data was analyzed using ANOVA and Bonferroni post hoc assessment. Fractographic analysis was performed with scanning electron microscopy (SEM). Results: The mean fracture load (standard deviation) was 1600 (350) N for TD; 1595 (479) N for MD; and 1571 (295) N for ME. When comparing the means of all data for each group (non-aged and aged), no statistically significant difference between groups was observed (p=0.970, F=0.030). However, some of the 120-day storage groups were significantly higher in value than the 7-day storage groups (p= <0.001, F= 7.561). SEM illustrated larger micro-fracture dimensions in Group MD than Group ME. Conclusion: Minimal thickness e.max crowns did not demonstrate statistical difference in fracture resistance from traditional thickness crowns. Fracture mechanisms of minimal thickness e.max crowns may be affected by the e-modulus of the substrate. Minimal thickness e.max crowns may be a viable restorative option when supported by high e-modulus materials.

description: We investigate the behavior of the light pulse in $Lambda$-type cold atomic gases with two counterpropagating control lights with equal strength by directly simulating the dynamic equations and exploring the dispersion relation. Our analysis shows that, depending on the length $L_0$ of the stored wave packet and the decay rate $γ$ of ground-spin coherence, the recreated light can behave differently. For long $L_0$ and/or large $γ$, a stationary light pulse is produced, while two propagating light pulses appear for short $L_0$ and/or small $γ$. In the $γ\to 0$ limit, the light always splits into two propagating pulses for sufficiently long time. This scenario agrees with a recent experiment [Y.-W.Lin, et al., Phys. Rev. Lett. 102, 213601(2009)] where two propagating light pulses are generated in laser-cooled cold atomic ensembles.

description: To achieve a sustainable urbanisation, urban planning and land management, need updated and geographically detailed data, which remain a challenge to find because of : The cost of generating such data through traditional methods intensive in field work, The shortage of skilled professionals in geospatial sciences, low national capacity of geospatial data production, The inertia regarding the change of routine workflows and adopting new practices that are not imposed through legal requirements. Earth Observation (EO) capabilities can provide useful information for decision making for sustainable urbanisation. Indeed, it can address the 2 first points : EO data are cheaper than field measures/observation to produce similar data, Training such as with IdeaMapSudan can contribute to skilled professionals. Artificial Intelligence (AI) allows the processing of big data sets, such as EO data on urban areas with very high spatial resolution to map small houses. The presentation concerns results from some ANAGEO (ULB) research projects (since 2014) using EO and AI using mainly Open Data and Software.

description: We investigate the signals of supersymmetry (SUSY) in a scenario where only the third family squarks and sleptons can be produced at the Large Hadron Collider (LHC), in addition to the gluino, charginos and neutralinos. The final states in such cases are marked by a multiplicity of top and/or bottom quarks. We study in particular, the case when the stop, sbottom and gluino masses are near the TeV scale due to which, the final state t's and b's are very energetic. We point out the difficulty in b-tagging and identifying energetic tops and suggest several event selection criteria which allow the signals to remain significantly above the standard model background. We show that such scenarios with gluino mass up to 2 TeV can be successfully probed at the LHC. Information on $\tan β$ can also be obtained by looking at associated Higgs production in the cascades of accompanying neutralinos. We also show that a combined analysis of event rates in the different channels and the effective mass distribution allows one to differentiate this scenario from the one where all three sfermion families are accessible.

description: This paper investigated the friction-induced vibration (FIV) behavior under the running-in process with oil lubrication. The FIV signal with periodic characteristics under lubrication was identified with the help of the squeal signal induced in an oil-free wear experiment and then extracted by the harmonic wavelet packet transform (HWPT). The variation of the FIV signal from running-in wear stage to steady wear stage was studied by its root mean square (RMS) values. The result indicates that the time-frequency characteristics of the FIV signals evolve with the wear process and can reflect the wear stages of the friction pairs. The RMS evolvement of the FIV signal is in the same trend to the composite surface roughness and demonstrates that the friction pair goes through the running-in wear stage and the steady wear stage. Therefore, the FIV signal with periodic characteristics can describe the evolvement of the running-in process and distinguish the running-in wear stage and the stable wear stage of the friction pair.

Coupled-oscillator models for vortex-induced oscillation of a circular cylinder
Creators: name: Wood, Kelvin Norman
Publisher: name: University of British Columbia
Year: 2010

description: The vortex-induced oscillation of a circular cylinder is modelled by a non-linear system with two degrees of freedom. The periodic lift acting on the cylinder due to the vortex-street wake is represented by a self-excited oscillator, which is coupled to the cylinder motion. Approximate solutions and stability criteria are presented which are valid over restricted intervals. Changes to the form of the coupled-oscillator model and its approximate solution are examined in order to improve the comparison between predicted model and experimental results. The changes are motivated by the study of experimental evidence, and by comparison with the known properties of similar systems of non-linear equations. Significant improvement in the coupled-oscillator model performance is obtained through the inclusion of an effective structural damping term which is dependent on wind speed and cylinder displacement.

We unify the two broken symmetries in a common complex order parameter and derive many experimentally relevant consequences such as the topology of the phase diagram in magnetic field and pressure. The theory accounts for the appearance of a moment under application of stress and the thermal expansion anomaly across the phase transitions. It identifies the low energy mode which is seen in the hidden order phase near the conmensurate wavector (0,0, 1) as the pseudo-Goldstone mode of the approximate U(1) symmetry.

description: Purpose: The purpose of this study was to identify whether adolescents who were aware of e-cigarette or vaping product use-associated lung injury (EVALI) were more likely to view e-cigarette use as harmful to their health and to describe the misconceptions adolescents may have regarding e-cigarette use. Methods: Adolescents aged 13-19 were recruited in pediatric dental clinics and completed a survey questionnaire regarding their knowledge of e-cigarettes. Results: A total of 66 adolescents participated. Forty-seven adolescents indicated knowledge of e-cigarettes. Forty adolescents recognized that most e-cigarettes contain nicotine and 49 adolescents reported knowledge of EVALI cases. Adolescents with knowledge of EVALI have increased awareness of possible lung damage from e-cigarette use (p=.001). Furthermore, adolescents with knowledge of EVALI cases are more aware that e-cigarettes contain nicotine (p=.049). Conclusions: Adolescents with knowledge of EVALI cases have increased awareness of lung damage resulting from e-cigarette use and are more likely to view e-cigarette use as harmful to their health. Furthermore, those who are aware of EVALI cases are more likely to recognize that e-cigarettes contain nicotine, which is known to be addictive and can cause long-term neurochemical changes in the brain. Targeted interventions to increase awareness regarding the harmful effects of e-cigarettes on health is needed to better address e-cigarette use in adolescents.

description: Gaze target detection aims at determining the image location where a person is looking. While existing studies have made significant progress in this area by regressing accurate gaze heatmaps, these achievements have largely relied on access to extensive labeled datasets, which demands substantial human labor. In this paper, our goal is to reduce the reliance on the size of labeled training data for gaze target detection. To achieve this, we propose AL-GTD, an innovative approach that integrates supervised and self-supervised losses within a novel sample acquisition function to perform active learning (AL). Additionally, it utilizes pseudo-labeling to mitigate distribution shifts during the training phase. AL-GTD achieves the best of all AUC results by utilizing only 40-50% of the training data, in contrast to state-of-the-art (SOTA) gaze target detectors requiring the entire training dataset to achieve the same performance. Importantly, AL-GTD quickly reaches satisfactory performance with 10-20% of the training data, showing the effectiveness of our acquisition function, which is able to acquire the most informative samples. We provide a comprehensive experimental analysis by adapting several AL methods for the task. AL-GTD outperforms AL competitors, simultaneously exhibiting superior performance compared to SOTA gaze target detectors when all are trained within a low-data regime.

description: The effect of ionized gas on the propagation of radio signals is known as plasma lensing. Unlike gravitational lensing, plasma lensing causes both magnification and strong de-magnification effects to background sources. We study the cross section of plasma lensing for two density profiles, the Gaussian and power-law models. In general, the cross section increases with the density gradient. Radio sources can be used to measure the free electron density along the line of sight. However, plasma lensing de-magnification causes an underestimate of the electron density. Such a bias increases with the electron density, and can be up to $\sim 15\%$ in the high density region. There is a large probability that high density clumps will be missed due to this bias. The magnification of plasma lensing can also change the luminosity function of the background sources. The number density of sources on both the high and low luminosity ends can be overestimated due to this biasing effect.

description: The CHORIZO project aims to improve the understanding of the impact of social norms on behaviours related to food waste generation. This document starts from the list of actions against Food Loss and Waste (FLW) collected within the CHORIZO project (Deliverable 1.2). It establishes the foundation for the conceptualization of interventions in relation to social norms and 'what-if' scenarios with a perspective of modelling effective 0FLW interventions.
This work emphasises the importance of targeted and customised interventions that include considerations on specific context-related social norms. A pivotal aspect in behavioural change interventions involves recognizing diverse social roles and settings. Here, we define the concept of social roles as expected behavioural patterns in specific contexts, exploring potential conflicts within or between these roles. In the context of the six Case Studies of the CHORIZO project, this work explores the relevant social norms within and beyond each setting, their targets groups and networks of influence. Furthermore, this report introduces potential 'what-if' scenarios emerging in the Case Studies, highlighting possible awareness-raising interventions, economic incentives and 'nudging' strategies related to social norms for 0FLW interventions. The importance of the co-design process is highlighted for the definition of possible settings (e.g., in-home settings, out-of-home settings and alternative settings) for the modelling of interventions, basing this segmentation on the similarities with the case studies in which to model interventions.
In summary, this work presents a new conceptualization for behavioural interventions in FLW reduction, integrating the identification and exploitation of social norms and social roles in the settings of their influence. This report serves as a basis for upcoming modelling activities, paving the way for a deeper understanding of how social norms influence food waste generation or reduction within the CHORIZO project.

description: Currently, consumers increasingly spend a considerable amount of their time online, and this has made marketers accordingly shift their focus away from traditional advertising toward online advertising. Banner ads are one of the most common forms of online advertising. However, despite its popularity, studies show that people often dislike advertising banners and try not to look at them when browsing. Marketers have always been trying to find appropriate methods to overcome consumers’ banner blindness. This research aims to compare the two strategies of a) nudging with a right-ad/right-time (RART) approach versus b) overwhelming with extreme creativity (XC). It used eye-tracking methods to see how well these strategies influenced consumers in an online environment. Our findings showed that creative ads are successful in drawing consumers’ attention and generating a positive attitude towards the brand and advertisement. However, they do not do well for memory-oriented measures. On the other hand, although personalized ads are not effective in catching consumer’s attention, they have a positive influence on memory. The study also suggests examining the level of brand familiarity for the next researches.

description: We investigate the two-orbital periodic Anderson model, where the local orbital fluctuations of f-electrons couple with a two-fold degenerate Jahn-Teller phonon, by using the dynamical mean-field theory. It is found that the heavy fermion state caused by the Coulomb interaction between f-electrons U is largely enhanced due to the electron-phonon coupling g, in contrast to the case with the single-orbital periodic Anderson model where the effects of U and g compete to each other. In the heavy fermion state for large $U$ and g, both the orbital and lattice fluctuations are enhanced, while the charge (valence) and spin fluctuations are suppressed. In the strong coupling regime, a sharp soft phonon mode with a large spectral weight is observed for small U, while a broad soft phonon mode with a small spectral weight is observed for large U. The cooperative effect of U and g for half-filling with two f-electrons per atom $n_f=2$ is more pronounced than that for quarter-filling with $n_f=1$.

description: Sufficient conditions are provided under which the log-likelihood ratio test statistic fails to have a limiting chi-squared distribution under the null hypothesis when testing between one and two components under a general two-component mixture model, but rather tends to infinity in probability. These conditions are verified when the component densities describe continuous-time, discrete-statespace Markov chains and the results are illustrated via a parametric bootstrap simulation on an analysis of the migrations over time of a set of corporate bonds ratings. The precise limiting distribution is derived in a simple case with two states, one of which is absorbing which leads to a right-censored exponential scale mixture model. In that case, when centred by a function growing logarithmically in the sample size, the statistic has a limiting distribution of Gumbel extreme-value type rather than chi-squared.

description: In accordance with the Treaty establishing the European Community (the Treaty), the main objective of the European System of Central Banks (ESCB) is the maintenance of price stability in the euro area. To this end, the Eurosystem – which comprises the European Central Bank (ECB) and the national central banks (NCBs) of the 11 Member States which have adopted the euro – carry out four basic tasks: the definition and implementation of the single monetary policy; the conduct of foreign exchange operations; the holding and management of official foreign reserves; and the promotion of the smooth operation of payment systems.In addition to these tasks, the Eurosystem performs a number of other functions, including those related to prudential supervision and the stability of the financial system. Although the primary responsibility for these functions has remained at the national level, the Eurosystem has been assigned some tasks in this area. The basic model which has been adopted by the European Community legislators for the Eurosystem in this field is that of a central bank which has no direct responsibility in the areas of prudential supervision but is nevertheless involved to a certain extent.In the following sections, the main tasks carried out by the Eurosystem and the ECB in the fields of prudential supervision and financial stability are outlined.
Grasping the Idea – With Your Hands? A tDCS Investigation of Embodied Simulation in Motor Metaphors

description: Reading literal descriptions of motor actions, like grasp the pen, leads to activation in corresponding areas of the motor and premotor cortices. According to theories of embodied cognition (e.g., Barsalou, 1999), such activation reflects embodied simulation of the motor action described in the text - a “partial re-experiencing” that activates the same neural areas as performing the action.The present study investigates whether motor simulations are similarly activated when action words are used nonliterally, as in the motor metaphor grasp the idea. I used anodal transcranial direct current stimulation (tDCS) to increase neuronal excitability in the left primary motor cortex while participants (N = 55) read short sentences and judged whether each sentence made sense. Participants read four categories of sentences: literal motor sentences (e.g., the architect grasped the pen), literal non-motor sentences (e.g. the student understood the idea), nonsense sentences (e.g. the man browsed the ball), and motor metaphors (e.g., the student grasped the idea), which varied in familiarity. Neurostimulation (anodal TDCS) significantly facilitated processing of literal motor sentences and motor metaphors, but not literal non-motor or nonsense sentences. Within motor metaphors, neurostimulation significantly facilitated processing of unfamiliar but not familiar expressions. These results indicate that embodied motor simulation facilitates processing of both literal and figurative uses of motor action words, suggesting that the figurative meaning is grounded in the literal meaning. In motor metaphors, the importance of embodied simulation decreases as familiarity increases, suggesting that the embodied pathway is eventually replaced with faster, non-embodied processing pathways as familiarity increases.

description: MG 2016+112 is a quadruply imaged lens system with two complete images A and B and a pair of merging partial images in region C as seen in the radio. The merging images are found to violate the expected mirror symmetry. This indicates an astrometric anomaly which could only be of gravitational origin and could arise due to substructure in the environment or line-of-sight of the lens galaxy. We present new high resolution multi-frequency VLBI observations at 1.7, 5 and 8.4 GHz. Three new components are detected in the new VLBI imaging of both the lensed images A and B. The expected opposite parity of the lensed images A and B was confirmed due to the detection of non-collinear components. Furthermore, the observed properties of the newly detected components are inconsistent with the predictions of previous mass models. We present new scenarios for the background quasar which are consistent with the new observations. We also investigate the role of the satellite galaxy situated at the same redshift as the main lensing galaxy. Our new mass models demonstrate quantitatively that the satellite galaxy is the primary cause of the astrometric anomaly found in region C. The detected satellite is consistent with the abundance of subhaloes expected in the halo from cold dark matter (CDM) simulations. However, the fraction of the total halo mass in the satellite as computed from lens modeling is found to be higher than that predicted by CDM simulations.

“Boxing Clever Cork saved my life”: a snapshot of an early addiction recovery fitness and education program

description: Boxing Clever Cork is an interagency program for people who have experienced or are experiencing problematic substance use. It integrates a fitness program with education, with the aim of reducing harm and supporting addiction recovery in the lives of participants. The aim of this research was to evaluate the Cork iteration of Boxing Clever, which originated in Ballymun, Dublin. A qualitative approach was taken to data collection, using the World Café1 method along with one to one interviewing, and data was analyzed using thematic analysis. Research participants described feelings of vulnerability and isolation during the embryonic stages of sobriety. Boxing Clever Cork introduced structure and purpose into their lives and created a model of peer-to-peer support within a newly formed early recovery community. Challenges encountered included the diverse stages of recovery within the group, however, despite these challenges research participants felt it was important that people actively using substances continued to be included in future programs. Professionals were motivated through the principles of social inclusion. Opportunities for development include community-based delivery, a peer mentorship model and provision of additional mental health supports.

description: We propose a new Universal Extra Dimensional model that is defined on a six-dimensional spacetime which has a two-sphere orbifold $S^2/Z_2$ as an extra-space. We specify our model by choosing the gauge symmetry as SU(3)$\timesSU(2)\timesU(1)_Y \timesU(1)_X$, introducing field contents in six-dimensions as their zero modes correspond to the Standard model particles, and determining a boundary condition of these fields on orbifold $S^2/Z_2$. A background gauge field that belongs to U(1)$_X$ is introduced there, which is necessary to obtain massless chiral fermions in four-dimensional spacetime. We then analyze Kaluza-Klein(KK) mode expansion of the fields in our model and derive the mass spectrum of the KK particles. We find that the lightest KK particles are the 1st KK particle of massless gauge bosons at tree level. We also discuss the KK parity of the KK modes in our model and confirm the stability of the lightest KK particle which is important for dark matter physics.

description: A non-Abelian flavour symmetry in a minimal supersymmetric standard model can explain the flavour structures in the Yukawa couplings and simultaneously solve the SUSY flavour problem. Similarly the SUSY CP problem can be solved if CP is spontaneously broken in the flavour sector. In this work, we present an explicit example of these statements with a SU(3) flavour symmetry and spontaneous CP violation. In addition, we show that it is still possible to find some significant deviation from the SM expectations as far as FCNC and CP violation are concerned. We find that large contributions can be expected in lepton flavour violating decays, as $μ\to e γ$ and $τ\to μγ$, electric dipole moments, $d_e$ and $d_n$ and kaon CP violating processes as $ε_K$. Thus, these flavoured MSSM realizations are phenomenologically sensitive to the experimental searches in the realm of flavor and CP vioation physics.
