description: Visually impaired individuals often face significant challenges in their daily lives, frequently relying on others for assistance and feeling less confident in unfamiliar environments. This paper presents an innovative IoT-based system designed to address these issues by aiding in obstacle and water puddle detection. The system comprises a walking stick integrated with an ESP32 microcontroller, an ultrasound sensor, and a smart phone application. The walking stick collects environmental data through the ultrasound sensor, which the ESP32 processes to identify obstacles. Communication between the microcontroller and the smart phone is facilitated via MIT App Inventor, enabling the app to deliver audible navigation instructions to users. The developed system demonstrated impressive performance, achieving an accuracy of 99.54% at a distance of 250 cm and 99.03% at 450cm. Additionally, it successfully detected obstacles at an angular position of up to 90 degrees. These results highlight the system effectiveness and efficiency in providing precise voice instructions, which are crucial for enhancing navigation for visually impaired individuals. By offering real-time feedback and detailed guidance, this system significantly improves the independence and safety of visually impaired users, boosting their confidence in navigating unfamiliar environments. Overall, the IoT-based navigation system represents a substantial advancement in assistive technology, promising a safer and more autonomous life for those with visual impairments.
The mass-Peak Patch algorithm for fast generation of deep all-sky dark matter halo catalogues and its N-Body validation

description: We present a detailed description and validation of our massively-parallel update to the mass-Peak Patch method, a fully predictive initial-space algorithm to quickly generate dark matter halo catalogues in very large cosmological volumes. We perform an extensive systematic comparison to a suite of N-body simulations covering a broad range of redshifts and simulation resolutions, and find that, without any parameter fitting, our method is able to generally reproduce N-body results while typically using over 3 orders of magnitude less CPU time, and a fraction of the memory cost. Instead of calculating the full non-linear gravitational collapse determined by an N-body simulation, the mass-Peak Patch method finds an overcomplete set of just-collapsed structures around a hierarchy of density-peak points by coarse-grained (homogeneous) ellipsoidal dynamics. A complete set of mass-peaks, or halos, is then determined by exclusion of overlapping patches, and second order Lagrangian displacements are used to move the halos to their final positions and to give their flow velocities. Our results show that the mass-Peak Patch method is well-suited for creating large ensembles of halo catalogues to mock cosmological surveys, and to aid in complex statistical interpretations of cosmological models.

Comparison of ZEUS Data with Standard Model Predictions for e^+ p -> e^+ X Scattering at High x and Q^2
Creators: name: ZEUS Collaboration

Publisher: name: arXiv
Year: 1997
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Using the ZEUS detector at HERA, we have studied the reaction e^+ p -> e^+ X for Q^2 > 5000 GeV^2 with a 20.1 pb^{-1} data sample collected during the years 1994 to 1996. For Q^2 below 15000 GeV^2, the data are in good agreement with Standard Model expectations. For Q^2 > 35000 Gev^2, two events are observed while 0.145+-0.013 events are expected. A statistical analysis of a large ensemble of simulated Standard Model experiments indicates that with probability 6.0%, an excess at least as unlikely as that observed would occur above some Q^2 cut. For x>0.55 and y>0.25, four events are observed where 0.91+-0.08 events are expected. A statistical analysis of the two-dimensional distribution of the events in x and y yields a probability of 0.72% for the region x>0.55 and y>0.25 and a probability of 7.8% for the entire Q^2 > 5000 GeV^2 data sample. The observed excess above Standard Model expectations is particularly interesting because it occurs in a previously unexplored kinematic region.

Dephasing at Low Temperatures

Subjects: subject: Condensed Matter (cond-mat)

description: We discuss the significance and the calculation of dephasing at low temperatures. The particle is moving diffusively due to a static disorder configuration, while the interference between classical paths is suppressed due to the interaction with a dynamical environment. At high temperatures we may use the `white noise approximation' (WNA), while at low temperatures we distinguish the contribution of `zero point fluctuations' (ZPF) from the `thermal noise contribution' (TNC). We study the limitations of the above semiclassical approach and suggest the required modifications. In particular we find that the ZPF contribution becomes irrelevant for thermal motion.

The trial wave function has a simple structure, combining two- and three-body correlation functions coming from a translationally invariant configuration-interaction description, and Jastrow-type short-range correlations. The calculated ground state energies differ by around 2% from the diffusion Monte Carlo results.

description: A systematic approach for the construction of a density functional for van der Waals interactions that also accounts for saturation effects is described, i.e. one that is applicable at short distances. A very efficient method to calculate the resulting expressions in the case of flat surfaces, a method leading to an order reduction in computational complexity, is presented. Results for the interaction of two parallel jellium slabs are shown to agree with those of a recent RPA calculation (J.F. Dobson and J. Wang, Phys. Rev. Lett. 82, 2123 1999). The method is easy to use; its input consists of the electron density of the system, and we show that it can be successfully approximated by the electron densities of the interacting fragments. Results for the surface correlation energy of jellium compare very well with those of other studies. The correlation-interaction energy between two parallel jellia is calculated for all separations d, and substantial saturation effects are predicted.

description: The purpose of this qualitative study is to examine the representation of new teachers in the teaching profession during the final years of the financial crisis. We conducted numerous interviews with Greek and French secondary school teachers (Philology-Science teachers) inAthens,Thessaloniki,Paris,Creteil. We used the semi-structured interview and the data was interpreted with the use of Thematic Analysis (Braun & Clark). A comparison of the learning en­vironments in two EU countries enables us to distinguish the working condi­tions while considering global developments. Furthermore, through this com­parison we examine the reasons behind the development of a new context of work and the representations of the teaching profession as shaped by current circumstances.
The study is part of our postdoctoral research (ΤΕΑΠΗ- UOA and Laboratoire CERLIS – Paris Descartes). It was co-funded by the State Scholarship Project (IKY) (NSRF, 2007-2013).

description: We exploit the fact that within massless perturbative QCD the same Green's function determines the hadronic contribution to the $τ$ decay width and the moments of the $e^+e^-$ cross section. This allows one to obtain relations between physical observables in the two processes up to an unprecedented high order of perturbative QCD. A precision measurement of the $τ$ decay width allows one then to predict the first few moments of the spectral density in $e^+e^-$ annihilations integrated up to $s\sim m_τ^2$ with high accuracy. The proposed tests are in reach of present experimental capabilities.

description: We consider the problem of smartphone video-based heart rate estimation, which typically relies on measuring the green color intensity of the user's skin. We describe a novel signal in fingertip videos used for smartphone-based heart rate estimation: fingertip contact surface area. We propose a model relating contact surface area to pressure, and validate it on a dataset of 786 videos from 62 participants by demonstrating a statistical correlation between contact surface area and green color intensity. We estimate heart rate on our dataset with two algorithms, a baseline using the green signal only and a novel algorithm based on both color and area. We demonstrate lower rates of substantial errors (>10 beats per minute) using the novel algorithm (4.1%), compared both to the baseline algorithm (6.4%) and to published results using commercial color-based applications (>6%).

description: The role of teachers in the multicultural classrooms impose many challeng­es, from promoting integration of students with an immigrant background, to preparing every student for a harmonious and creative coexistence in a mod­ern multicultural society. In order for the teacher to cope with these challeng­es, he/she needs appropriate preparation during his/her initial education and the necessary in-service training. This brings up the question “what should be the content of teachers’ initial education or training programs so that teachers acquire knowledge, skills and attitudes to be effective in their work, in a het­erogeneous, multicultural environment?” This quantitative study is based on 708 records of a needs assesment survey, conducted among primary and sec­ondary education teachers.

Magneto Rotational Instability in Magnetized AGN Tori

description: It is widely believed that in active galactic nuclei (AGNs) a supermassive black hole with an accretion disk is surrounded by an optically and geometrically thick torus at sub-parsec scale. However, it is not clear how is the mass supply toward the central engine caused and how it is related with the internal structures of the tori. The magnetic field in the tori may contribute to the accretion process via the magneto-rotational instability (MRI). Using global three dimensional magnetohydrodynamic (MHD) simulations taking the effects of X-ray heating and radiative cooling into account studied the numerical resolution for azimuthal direction for MRI driving. We found that a strongly magnetized disk consisted of a cold ($< 10^3$ K) and warm ($10^4$ K) gas is developed in about 30 rotational periods. We also found in high resolution model that the mean azimuthal magnetic fields reverse their direction quasi-periodically. We confirmed that the typical wave length of the MRI should be resolved with a least 20 azimuthal grid cells.

description: This research investigates the teachers’ views on the subjects they need to be trained and the factors which facilitate or not their participation in lifelong professional development. The quantitative survey was conducted among sec­ondary teachers, using the adjusted TALIS (2013) questionnaire. As teacher report, they have a high need for training in vocational guidance and student counseling, teaching in a multicultural setting, teaching students with special needs, technology, as well as approaches to individualized learning. Teachers prefer engaging themselves in courses and formally structured workshops as well as sample teaching based on ICT. Barriers to teachers’ participation in professional development are the lack of incentives and time. Finally, teacher mobility and professional satisfaction were studied as professional develop­ment factors. One third of teachers have travelled abroad, accompanying stu­dents, while most teachers are satisfied with their job, as they consider it of great value for the society.

description: The dynamics of phase-separation in conserved systems with an O(N) continuous symmetry is investigated in the presence of an order parameter dependent mobility M(ϕ)=1-a ϕ^2. The model is studied analytically in the framework of the large-N approximation and by numerical simulations of the N=2, N=3 and N=4 cases in d=2, for both critical and off-critical quenches. We show the existence of a new universality class for a=1 characterized by a growth law of the typical length L(t) ~ t^{1/z} with dynamical exponent z=6 as opposed to the usual value z=4 which is recovered for a<1.

description: The implementation of inclusive education seems to bump onto current ideol­ogy of contemporary education systems and the curriculum, which are based on the prevalent education policy that sets utilitarian goals. As a result, unfair procedures and functions are underpinned, which produce and reproduce so­cial discrimination. Barriers to inclusion are raised by several methods, such as the prevalent rhetoric in the curriculum about children with disabilities, the hidden curriculum and the monolithic assessment methods, which are formed by the social hierarchy and the dominant power relations. Thus, despite the basic tenets of inclusion education, children with disabilities in contemporary schools are excluded and marginalized. Hence, it seems essential to reform the curriculum and render it inclusive. To this end, curricula should constitute the means to promote cognitive and emotional development of children. Therefore, curricula should propose the tools to raise the barriers to inclusion and provide equal opportunities in quality learning. In this way, inclusive education may be established in the short and long-term.

description: This paper focuses on the development of Second Chance Schools (SCS), an innovative institution established inGreece, in1997. Inparticular, the repro­duction of the culture of Second Chance Schools is investigated during the third phase of their function (2008-2015). The headmasters’ οf SCS, the teach­ing staff and the local teachers’ unions addressed formal complaints during the 2008-2015 period, mainly in relation to institutional changes implemented in the schools, in 2008. Those reforms led to shortage of basic elements of inno­vation. The theoretical framework of this paper is based on the organisational theory of the school culture. Qualitative analysis was used as part of the meth­odology implemented to the data provided. This analysis verified the strength of SCS as an institution and laid the foundation for better understanding of their role in the society. Teachers of the SCS have become well acquainted of the functionality and purpose of those schools and collectively appreciate their institutional values and principles.

description: Starting from a t-J model, we introduce inhomogeneous terms to mimic stripes. We find that if the inhomogeneous terms break the SU(2) spin symmetry the binding between holes is tremendously enhanced in the thermodynamic limit. In any other model (including homogeneous models) the binding in the thermodynamic limit is small or neglible. By including these inhomogeneous terms we can reproduce experimental neutron scattering data. We also discuss the connection of the resulting inhomogeneity-induced superconductivity to recent experimental evidence for a linear relation between magnetic incommensurability and the superconducting transition temperature, as a function of doping.

Development of a gut microbe-targeted nonlethal therapeutic to inhibit thrombosis potential.

Subjects: subject: 110201 Cardiology (incl. Cardiovascular Diseases)

description: Trimethylamine N-oxide (TMAO) is a gut microbiota-derived metabolite that enhances both platelet responsiveness and in vivo thrombosis potential in animal models, and TMAO plasma levels predict incident atherothrombotic event risks in human clinical studies. TMAO is formed by gut microbe-dependent metabolism of trimethylamine (TMA) moiety-containing nutrients, which are abundant in a Western diet. Here, using a mechanism-based inhibitor approach targeting a major microbial TMA-generating enzyme pair, CutC and CutD (CutC/D), we developed inhibitors that are potent, time-dependent, and irreversible and that do not affect commensal viability. In animal models, a single oral dose of a CutC/D inhibitor significantly reduced plasma TMAO levels for up to 3 d and rescued diet-induced enhanced platelet responsiveness and thrombus formation, without observable toxicity or increased bleeding risk. The inhibitor selectively accumulated within intestinal microbes to millimolar levels, a concentration over 1-million-fold higher than needed for a therapeutic effect. These studies reveal that mechanism-based inhibition of gut microbial TMA and TMAO production reduces thrombosis potential, a critical adverse complication in heart disease. They also offer a generalizable approach for the selective nonlethal targeting of gut microbial enzymes linked to host disease limiting systemic exposure of the inhibitor in the host.

description: Pb‐free halide perovskites have recently attracted immense attention due to the number of advantages in their optical and electronic properties. However, tuning the optical bandgap with minimized amounts of point defects is a particularly challenging task in photovoltaics. It is pivotal to clearly understand the detailed relationship between the bandgap change with defect generation and charge carrier lifetime. In this study, Cs₃Sb₂I₉ crystals are synthesized by varied choice of solvents, namely, γ‐butyrolactone, a mixture of dimethylformamide and dimethyl sulfoxide, and hydroiodic acid. Although the same principles of decreasing solubility and crystallization are applied, Cs₃Sb₂I₉ crystals with different size and shape in microscopic and macroscopic scale are obtained during heating and cooling of the solution. The synthesized crystals are investigated using a combination of different spectroscopies including Raman, UV–visible, and time‐resolved photoluminescence. In the results, it is suggested that there is a strong relationship between Urbach energy and the lifetime of charge carriers. In this research, readily applicable practical principles and examples of how to control the defects for the advancement in Pb‐free perovskite photovoltaics are provided.

description: We have studied sidebranching induced by fluctuations in dendritic growth. The amplitude of sidebranching induced by internal (equilibrium) concentration fluctuations in the case of solidification with solutal diffusion is computed. This amplitude turns out to be significantly smaller than values reported in previous experiments.The effects of other possible sources of fluctuations (of an external origin)are examined by introducing non-conserved noise in a phase-field model. This reproduces the characteristics of sidebranching found in experiments. Results also show that sidebranching induced by external noise is qualitatively similar to that of internal noise, and it is only distinguished by its amplitude.

description: We consider a general class of models with gauge-mediated supersymmetry breaking in which the gravitino is the lightest supersymmetric particle. Several qualitatively different scenarios arise for the phenomenology of such models, depending on which superpartner(s) decay dominantly to the gravitino. At LEP2, neutralino pair production and slepton pair production can lead to a variety of promising discovery signals, which we systematically study. We investigate the impact of backgrounds for these signals and show how they can be reduced, and outline the effects of model parameter variations on the discovery potential.

description: This research focuses on the study of the Schoolbooks of the High School in the Literature Course. In particular, the field of research is the textbooks of B΄ and C΄ of High school. It sets out the following specific objectives: a) to ana­lyze the content of the introductory notes: as texts giving simple information to the teacher or methodological tools of the didactic act; and b) to compare the introductory notes of the two textbooks: how they respond to the different treatment of the content in each class (thematic and historical matter layout). From the content analysis and the resulting categories it appeared that the in­troductory notes of the textbooks are used as texts that simply provide some information to the teacher and the student about the literature texts and to a lesser extent as teaching and methodological guidance tools with reference to the special nature of the course of Literature.

description: Biotechnology offers many opportunities for the sustainable manufacturing of valuable products. The toolbox to optimize bioprocesses includes extracellular process elements such as the bioreactor design and mode of operation, medium formulation, culture conditions, feeding rates, and so on. However, these elements are frequently insufficient for achieving optimal process performance or precise product composition. One can use metabolic and genetic engineering methods for optimization at the intracellular level. Nevertheless, those are often of static nature, failing when applied to dynamic processes or if disturbances occur. Furthermore, many bioprocesses are optimized empirically and implemented with little‐to‐no feedback control to counteract disturbances. The concept of cybergenetics has opened new possibilities to optimize bioprocesses by enabling online modulation of the gene expression of metabolism‐relevant proteins via external inputs (e.g., light intensity in optogenetics). Here, we fuse cybergenetics with model‐based optimization and predictive control for optimizing dynamic bioprocesses. To do so, we propose to use dynamic constraint‐based models that integrate the dynamics of metabolic reactions, resource allocation, and inducible gene expression. We formulate a model‐based optimal control problem to find the optimal process inputs. Furthermore, we propose using model predictive control to address uncertainties via online feedback. We focus on fed‐batch processes, where the substrate feeding rate is an additional optimization variable. As a simulation example, we show the optogenetic control of the ATPase enzyme complex for dynamic modulation of enforced ATP wasting to adjust product yield and productivity.

description: An effective Hamiltonian is derived in the case of the strong Hund coupling and on-site Coulomb interaction by means of a projective perturbation approach. A physical mechanism for charge ordering in half-doped manganites (R_{0.5}X_{0.5}MnO_3) is proposed. The virtual process of electron hopping results in antiferromagnetic superexchange and a repulsive interaction, which may drive electrons to form a Wigner lattice. The phase diagram of the ground state of the model is presented at half doping. In the case of formation of Wigner lattice, we prove that spins of electrons are aligned ferromagnetically as well as that the localized spin background is antiferromagnetic. The influence of the on-site Coulomb interaction is also discussed.

description: Machine Reading Comprehension (MRC) with multiple-choice questions requires the machine to read given passage and select the correct answer among several candidates. In this paper, we propose a novel approach called Convolutional Spatial Attention (CSA) model which can better handle the MRC with multiple-choice questions. The proposed model could fully extract the mutual information among the passage, question, and the candidates, to form the enriched representations. Furthermore, to merge various attention results, we propose to use convolutional operation to dynamically summarize the attention values within the different size of regions. Experimental results show that the proposed model could give substantial improvements over various state-of-the-art systems on both RACE and SemEval-2018 Task11 datasets.

description: The present study aims to explore the career interests of high school students with special learning difficulties - dyslexia (GDD) with a gender perspective. Using the multistage sampling, the Pedagogical Institute's Questionnaire for Occupational Interests (TEEP) was awarded to a sample of 346 students attending schools in the wider region of Attica. The results of the research demonstrate the stereotypical choice of professional interests of students with special learning difficulties – dyslexia. In particular: a) students (boys) with special learning difficulties-dyslexia, demonstrate a practical and organizational type of career interests while b) students (girls) with special learning difficulties-dyslexia, demonstrate artistic and social types of career interests.

description: Spin-orbit scattering suppresses Zeeman splitting of individual energy levels in small metal particles. This suppression becomes significant when the spin-orbit scattering rate τ_{so}^{-1} is comparable with the quantum level spacing δ. The g-factor exhibits mesoscopic fluctuations; at small δτ_{so} it is distributed according to the Maxwell distribution. At δτ_{so}\to 0 the average g-factor levels off at a small value g\sim(l/L)^{1/2} given by the ratio of the electron mean free path l to the particle size L. On the contrary, in 2D quantum dots the g-factor is strongly enhanced by spin-orbit coupling.

description: The complexity and variability of our era has not left unchanged the schooling environment making primary schools’ principals undertake new roles. Time traps do not allow principals to complete successfully their complex tasks. Time traps come from the persons themselves and the wider working and social environment as well. The present study pointed out the lack of training in time management techniques and the fragmentary dealing of the “thieves” of time on behalf of principals.

Configuration entropy in the $Λ$CDM and the dynamical dark energy models: Can we distinguish one from the other?

description: The evolution of the configuration entropy of the mass distribution in the Universe is known to be governed by the growth rate of density perturbations and the expansion rate of the Universe. We consider the $Λ$CDM model and a set of dynamical dark energy models with different parametrization of the equation of state and explore the evolution of the configuration entropy in these models. We find that the nature of evolution of the configuration entropy depends on the adopted parametrization which may allow us to discern them from each other. The configuration entropy initially decreases with time but nearly plateaus out at present in the $Λ$CDM model. The models where dark energy becomes less dominant at late times exhibit a larger decrease in the configuration entropy compared to the $Λ$CDM model after redshift $z \sim 1$. We find that the configuration entropy remains nearly unchanged in the models where dark energy becomes more dominant at late times. Our results suggest that the method presented here may be also used to constrain the initial value of the configuration entropy of the Universe.

description: Patients with atrial fibrillation (AF) are often treated with antiarrhythmic drugs (AADs) to maintain sinus rhythm and with heart rate-lowering drugs to achieve the optimal rate control. In this study, we investigated trends in the use of AADs and rate control drugs in Finnish patients with AF. The Finnish AntiCoagulation in Atrial Fibrillation (FinACAF) study is a nationwide study including all patients with AF in Finland from 2007 to 2018. The number of AAD purchases and the proportions of all prevalent AF patients in a certain year of interest were calculated. In total, 391030 AF patients were identified between 2007 and 2018, and 39,816 (10.2%) of them had purchased either class I or III AADs. The proportion of patients using classes I and III AADs decreased from 8.6% to 6.3%. Flecainide and amiodarone were the most often used AADs. The use of flecainide and amiodarone decreased from 4.9% to 3.9% and 1.9% to 1.5%, respectively. The proportion of patients on beta-blockers remained stable at 75%. Dronedarone became available in 2011 when it also was the most used (0.8% of patients), but the use decreased thereafter. The use of sotalol and digoxin decreased from 1.5% to 0.6% and 24.6% to 11.0% over the study period. The number of AAD purchases increased alongside with the increasing prevalence of AF, whereas the proportion of AF patients on classes I and III AADs and digoxin decreased between 2007 and 2018. Flecainide remained the most used AAD followed by amiodarone.

description: The pattern selection problem in binary-mixture convection in an extended channel with a lateral through-flow is presented. The through-flow breaks left--right parity and changes pattern dynamics dramatically. The problem is studied based on computer simulation of the complete set of hydrodynamic equations (Oberbeck-Boussinesq approximation) in the two-dimensional rectangular channel with aspect ratio $Γ= 12$ and convection-suppressing lateral boundary conditions. A wide variety of new dynamical patterns is obtained, discussed and classified.

description: After we explain initially the differences between the assessment of the learning process and the assessment of a student’s performance, we analyse all the parameters on the basis of which a student and his/her performance are assessed. Finally, we present and evaluate all current trends that modernise the assessment methods and techniques related to the learning process and student performance, and also stress the basic logic and philosophy that govern these new approaches and also the points that makes them different from what was applied in the field of student assessment until recently.
