description: We study the dynamics of quantum statistical ensembles at first-order phase transition points of finite macroscopic systems. First, we show that at the first-order phase transition point of systems with an order parameter that does not commute with the Hamiltonian, any quantum state with a non-zero value of the order parameter always evolves towards a macroscopically distinct state after a sufficiently long time. From this result, we argue that stationarity required for statistical ensembles should be interpreted as stationarity on a sufficiently long but finite time scale. Finally, we prove that the density matrix of the squeezed ensemble, a class of generalized statistical ensembles proposed as the only concrete method of constructing phase coexistence states applicable to general quantum systems, is locally stationary on time scales diverging in the thermodynamic limit. Our results support the validity of the squeezed ensemble from a dynamical point of view and open the door to non-equilibrium statistical physics at the first-order phase transition point.

Η ενσυναίσθηση, ως έννοια στην Ιστορία, ταυτίζεται με τη διανοητική διαδικασία κατανόησης των αξιών, των σκέψεων, των κινήτρων και των επιδιώξεων των ιστορικών προσώπων. Παράλληλα, δομήθηκε έρευνα, με σκοπό να εξεταστεί κατά πόσον η συγκεκριμένη στρατηγική μάθησης συνέδραμε στην επίτευξη του αρχικού στόχου, αν και σε ποιο βαθμό βοήθησε τους μαθητές/τριες να κατανοήσουν πληρέστερα τα εξεταζόμενα ιστορικά γεγονότα, αλλά και κατά πόσον συνετέλεσε, ώστε να μετασχηματιστεί η αρχική στάση των μαθητών/τριών απέναντι στο γνωστικό αντικείμενο της Ιστορίας, που, συχνά, θεωρείται «ανιαρό ή ανούσιο».

description: As a prototype of the Weyl superconductor, layered molybdenum telluride (MoTe2) encompasses two semimetallic phases (1T_prime and Td) which differentiate from each other via a slight tilting of the out-of-plane lattice. Both phases are subjected to serious phase mixing which complicates the analysis of its origin of superconductivity. Herein, we explore the electron-phonon coupling (EPC) of the monolayer semimetallic MoTe2, without phase ambiguity under this thickness limit. Apart from the hardening or softening of phonon modes, the strength of the EPC can be strongly modulated by doping. Specifically, longitudinal and out-of-plane acoustic modes are significantly activated for electron doped MoTe2. This is ascribed to the presence of rich valley states and equispaced nesting bands which are dynamically populated under charge doping. Through comparing the monolayer and bilayer MoTe2, the strength of EPC is found to be less likely to depend on thickness for neutral samples but clearly promoted for thinner samples with electron doping, while for hole doping, the strength alters more significantly with the thickness than doping. Our work explains the puzzling issue of the doping sensitivity of the superconductivity in semimetallic MoTe2 and establishes the critical role of activating acoustic phonons in such low-dimensional materials.

description: In this article, we present a simple, inexpensive, and effective method for measuring the capacitor charge and discharge processes using a light-emitting diode (LED) and the light meter of a smartphone. We propose a simple circuit in which the LED's brightness is linear on the capacitor's voltage, allowing us to use the smartphone to monitor the capacitor state accurately. The method is tested experimentally, giving highly satisfactory results. Its exceptional combination of accuracy, minimal requirements, and ease of setup makes it an excellent way to introduce undergraduate students to the concepts of electricity and electronics in any educational setting.

description: Η Τέχνη, σε όλες τις εκφάνσεις της, χρησιμοποιήθηκε από την εξουσία και με σκοπό την εξαπάτηση του κοινού μέσα από την κατασκευή μιας πλαστής και καλλωπισμένης εικόνας, διαφορετικής ως προς την πραγματικότητα. Με την άνοδο του Χίτλερ στην εξουσία και την εγκαθίδρυση του ναζιστικού καθεστώτος το 1933, η Γερμανία εισήλθε σε μια σκοτεινή περίοδο. H ελεύθερη έκφραση και η ανεξάρτητη καλλιτεχνική δημιουργία αποτέλεσαν ασυμβίβαστες ιδέες, με την ολοκληρωτική αφοσίωση στο ιδεώδες της ανώτερης γερμανικής φυλής που απαιτούσαν οι εθνικοσοσιαλιστές ηγέτες. Μία διάσταση της πολιτιστικής πολιτικής της Εθνικοσοσιαλιστικής Γερμανίας, η οποία δεν έχει μελετηθεί επαρκώς, είναι αυτή της μουσικής. Πολλοί ιστορικοί, δημοσιογράφοι, πολιτικοί επιστήμονες, κοινωνιολόγοι, άνθρωποι των γραμμάτων αλλά και καθημερινοί πολίτες ασχολήθηκαν με τους τομείς της πολιτιστικής πολιτικής της ναζιστικής Γερμανίας, όπως ο κινηματογράφος, η αρχιτεκτονική, η γλυπτική, έχουν μελετηθεί αρκετά και υπάρχουν αρκετές αξιόλογες μελέτες, αντίθετα με την τέχνη της μουσικής που η προσοχή που έχει δοθεί είναι πολύ μικρή. Κι, όμως, αποτελεί μία σημαντική πτυχή της πολιτικής του Γ’ Ράιχ, αφού, μέσα από τη μουσική, εκφράζονταν οι εθνικοσοσιαλιστικές αξίες και ιδέες, όπως συνέβαινε και με άλλες τέχνες, λ.χ. τη γλυπτική. Η επιδίωξη για φυλετική και αισθητική κάθαρση του Γ΄ Ραιχ άγγιξε όλες τις μορφές της τέχνης. Οι μοντέρνες τεχνοτροπίες κηρύχθηκαν ως «εκφυλισμένες», από τον ιμπρεσιονισμό και τον φοβισμό ως το νταντά και τον σουρεαλισμό, περνώντας από τον κυβισμό, τον εξπρεσιονισμό και τη νέα αντικειμενικότητα. Οι Ναζί ένιωθαν αηδία για την τέχνη της περιόδου της Δημοκρατίας της Βαϊμάρης. Αυτή η αντιμετώπιση πήγαζε, εν μέρει, από τη συντηρητική αισθητική τους, αλλά και από την πρόθεσή τους να χρησιμοποιήσουν την τέχνη σαν μέσο προπαγάνδας.

The Impact of Depression on Motivated Behavior in Autism Spectrum Disorder
Creators: name: Shah, Jasmine S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Though Autism Spectrum Disorder (ASD) and Major Depressive Disorder (MDD) are distinct
disorders, they have both been shown to present with reward processing deficits. Specifically,
both disorders are characterized by decreased anticipation of rewarding stimuli. Because there is
a 43% comorbidity rate of MDD in ASD, the present study examined the relation of depressive
symptoms and hedonic capacity with effort-based decision-making in adolescents with ASD. We
utilized a sample of 49 adolescents with high-functioning ASD garnered from a larger study in
the laboratory. Depressive symptoms were measured with the Mini International
Neuropsychiatric Review (MINI), the Child Depression Inventory (CDI), and Beck Depression
Inventory (BDI). The Temporal Experience of Pleasure Scale (TEPS) was used to measure
hedonic capacity, and the Effort Expenditure for Rewards Task (EEfRT) was used to measure
effort-based decision-making. Results showed significant relations between dimensional
measures of depressive symptoms and hedonic capacity with effort-based decision-making, but
no significant relations between categorical diagnoses of MDD and effort-based decision-making.
These results suggest that depressive symptoms, specifically anhedonia, and hedonic capacity
should be considered as important explanatory mechanisms for the impaired reward processing
seen in ASD.

description: We propose a solution to the puzzle of dimensional reduction in the random field Ising model, inverting the question and asking: to what random problem in $D=d+2$ dimensions does a pure system in $d$ dimensions correspond? We consider two models: a continuum binary fluid, and a lattice gas which maps exactly onto an Ising model. In both cases we show that the mean density and other observables are equal to those of a similar model in $D$ dimensions, but with interactions and correlated disorder in the extra two dimensions of range $\propto l$, in the limit as $l\to\infty$. There is no conflict with rigorous results that the finite range model with locally correlated disorder orders in $D=3$. Our arguments avoid the use of replicas and perturbative field theory, instead being based on convergent cluster expansions, which, for the lattice gas, may be extended all the way to the critical point by virtue of the Lee-Yang theorem. Although the results may be viewed as a consequence of Parisi-Sourlas supersymmetry, they follow more directly from Kirchhoff's matrix-tree theorem.

 Type (lectotype designated here):— GUATEMALA. [Alta Verapaz:] Cubilqüitz, 350 m, Aug 1907, von Tuerckheim II 59 (BR barcode 000000552878 [digital photo!], isolectotypes E barcode E00190704 [digital photo!], M [cited by Bitter (1919), not found at M], NY barcode 00007318 [digital photo!], NY barcode 00007334 [digital photo!], U barcode U-0113931 [digital photo!], US barcode 00027489 [digital photo!], WIS!).
 Nomenclatural notes:—Bitter cited two gatherings in the protologue, and he cited the herbaria that housed the specimens that he examined: von Tuerckheim II 59 (M) and Donn. Sm. 7637 (B and M). We could not locate the original syntypes seen and cited by Bitter at M or at B, and no F photo negative of the B specimens is available. However, the gathering of von Tuerckheim II 59 was widely distributed and we were able to trace specimens in the herbaria BR, E, M, NY, U, US, and WIS: (BR barcode 000000552878, E barcode E00190704, M [cited by Bitter (1919), not found at M], NY barcode 00007318, NY barcode 00007334, U barcode U-0113931, US barcode 00027489, WIS). Therefore, we are designating an isosyntype at BR (BR barcode 000000552878) as the lectotype of the name Lycianthes nitida. Although Bitter did not mention or annotate the BR specimen, it is considered part of the original material (see Art. 9.3(c) of the ICN, McNeill et al. 2012).
 Taxonomic notes:— Lycianthes nitida is a relatively common and widely distributed (southern Mexico through Central America) epiphytic herb or shrub with glabrous foliage and purple, stellate corollas.

description: In this paper we demonstrate the agreement of jet-veto resummation and pT resummation for explaining the WW cross sections at Run 1 of the LHC, and in the future. These two resummation techniques resum different logarithms, however via reweighting methods they can be compared for various differential or exclusive cross sections. We find excellent agreement between the two resummation methods for predicting the zero-jet cross section, and propose a new reweighting method for jet-veto resummation that can be used to compare other differential distributions. We advocate a cross-channel comparison for the high-luminosity run of the LHC as both a test of QCD and new physics.

Wave Attenuation in Salt Marshes
Creators: name: Krovetz, Katharine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Salt marshes can provide several ecosystem services including shoreline protection. One of the ways marshes do this is by attenuating waves. However, the rate at which waves are attenuated by marshes is highly variable. Previous studies have found that the rate of wave attenuation varies with water depth, vegetation characteristics, bottom profile, and wave conditions. This study examined how these factors affect wave attenuation rate at four marsh sites in coastal North Carolina with different vegetation and bottom profile characteristics. The rate of wave attenuation was found to increase with decreasing water depth and increasing vegetation height and increasing vegetation density. Sites with short vegetation, which is submerged more of the time, had larger rates of decrease in wave attenuation with increasing depth than sites with tall vegetation. Waves with long periods were attenuated less than waves with short periods. Attenuation rates were much less and decreased more with increasing water depth during storm conditions than during normal conditions at the same site.

Analytical models for temperature dependence, effective spring constants, and mechanical mode frequencies are described and shown to be in good agreement with experimental results. The cavities exhibit mode volumes as small as $\sim10λ^3$, reflectance-limited finesse $\sim3\times10^3$, and mechanical resonance frequencies in the MHz range. Monolithic cavity arrays of this type might be of interest for applications in sensing, cavity quantum electrodynamics, and optomechanics.

description: We propose a theoretical framework of a magnetization switching induced solely by a microwave. The microwave frequency is always close to but slightly different from the oscillation frequency of the magnetization. By efficiently absorbing energy from the microwave, the magnetization climbs up the energy landscape to synchronize the precession with the microwave. We introduced a dimensionless parameter $ε$ determining the difference between the microwave frequency and the instant oscillation frequency of the magnetization. We analytically derived the condition of $ε$ to switch the magnetization, and confirmed its validity by the comparison with numerical simulations.

description: UniSpeech has achieved superior performance in cross-lingual automatic speech recognition (ASR) by explicitly aligning latent representations to phoneme units using multi-task self-supervised learning. While the learned representations transfer well from high-resource to low-resource languages, predicting words directly from these phonetic representations in downstream ASR is challenging. In this paper, we propose TranUSR, a two-stage model comprising a pre-trained UniData2vec and a phoneme-to-word Transcoder. Different from UniSpeech, UniData2vec replaces the quantized discrete representations with continuous and contextual representations from a teacher model for phonetically-aware pre-training. Then, Transcoder learns to translate phonemes to words with the aid of extra texts, enabling direct word generation. Experiments on Common Voice show that UniData2vec reduces PER by 5.3% compared to UniSpeech, while Transcoder yields a 14.4% WER reduction compared to grapheme fine-tuning.

description: Despite numerous applications of two-dimensional plasmons for electromagnetic energy manipulation at the nanoscale, their quantitative refraction and reflection laws (analogs of Fresnel formulas in optics) have not yet been established. This fact can be traced down to the strong non-locality of equations governing the 2d plasmon propagation. Here, we tackle this difficulty by direct solution of plasmon scattering problem with Wiener-Hopf technique. We obtain the reflection and transmission coefficients for 2d plasmons at the discontinuity of 2d conductivity at arbitrary incidence angle, for both gated and non-gated 2d systems. At a certain incidence angle, the absolute reflectivity has a pronounced dip reaching zero for gated plasmons. The dip is associated with wave passage causing no dynamic charge accumulation at the boundary. For all incidence angles, the reflection has a non-trivial phase different from zero and $π$.

Effects of Hind Limb Unloading and Spaceflight on Structural Properties of the Proximal Tibia
Creators: name: Comte, Taylor
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Unloading during spaceflight alters the microstructure of bone resulting in a significant reduction in bone health. Hind Limb Unloading (HLU) in mice is used to study the musculoskeletal changes caused by spaceflight. This study investigates the effects of HLU on bone stiffness and structural efficiency using Finite Element Analysis (FEA) on the proximal tibia of mice from a HLU study mimicking space shuttle mission STS-135 (13-days of spaceflight). Structural bone health was compared between HLU and spaceflight in terms of bone stiffness and structural efficiency as well as their response to Sclerostin antibody (Scl-Ab). HLU and spaceflight had the same effect on BV (-17%); however, spaceflight caused a greater decrease in stiffness (-34%) compared to HLU (-22%). Scl-Ab prevented the loss of BV and stiffness in the HLU and spaceflight groups. The spaceflight model showed a greater decrease in structural efficiency (-22%) between the flight vehicle and ground control groups compared to HLU (-5%). The difference in structural efficiency from unloading can be attributed to the incomplete unloading in HLU. Future studies should investigate the mechanisms resulting in the changes in structural efficiency to further characterize differences in the HLU model and microgravity in spaceflight.

description: The results are presented on the study of the electronic structure of thorium atoms adsorbed by the liquid atomic layer deposition from aqueous solution of thorium nitrate on the surface of CaF2. The chemical state of the atoms and the change of the band structure in the surface layers of Th/CaF2 system on CaF2 substrate were investigated by XPS and REELS techniques. It was found that REELS spectra for Th/CaF2 system include peaks in the region of low energy losses (3-7 eV) which are missing in the similar spectra for pure CaF2. It is concluded that the presence of the observed features in the REELS spectra is associated with the chemical state of thorium atoms and is caused by the presence of uncompensated chemical bonds at the Th/CaF2 interface, and, therefore, by the presence of unbound 6d- and 7s-electrons of thorium atoms. Assuming the equivalence of the electronic configuration of thorium-229 and thorium-232 atoms, an estimate was made on the time decay of the excited state of thorium-229 nuclei through the channel of the electron conversion. It was found that the relaxation time is about 40 μs for 6d-electrons, and about 1 μs for 7s-electrons.

description: We present a study of the detectability of transient events associated with galaxies for the Gaia European Space Agency astrometric mission. We simulated the on-board detections, and on-ground processing for a mock galaxy catalogue to establish the properties required for the discovery of transient events by Gaia, specifically tidal disruption events (TDEs) and supernovae (SNe). Transients may either be discovered by the on-board detection of a new source or by the brightening of a previously known source. We show that Gaia transients can be identified as new detections on-board for offsets from the host galaxy nucleus of 0.1--0.5,arcsec, depending on magnitude and scanning angle. The Gaia detection system shows no significant loss of SNe at close radial distances to the nucleus. We used the detection efficiencies to predict the number of transients events discovered by Gaia. For a limiting magnitude of 19, we expect around 1300 SNe per year: 65% SN Ia, 28% SN II and 7% SN Ibc, and ~20 TDEs per year.

description: Η εργασία με τον τίτλο «Βίνσεντ βαν Γκογκ: Ένα ταξίδι στον Εξπρεσιονισμό, στη φύση και στον άνθρωπο» ξεκίνησε, με αφορμή τον προσωπικό μου θαυμασμό στον Βίνσεντ βαν Γκογκ, στο πλαίσιο του μαθήματος: «Πολιτισμικές Σπουδές: Εφαρμογές στο πεδίο των ταινιών τεκμηρίωσης και του πολιτιστικού ντοκιμαντέρ», με διδάσκουσες τις Διαμαντοπούλου Ε. και Νικολαΐδου Α., για το διιδρυματικό μεταπτυχιακό πρόγραμμα: «Τεχνολογίες της Πληροφορίας και της Επικοινωνίας για την Εκπαίδευση». Οι αυτοπροσωπογραφίες του, οι προσωπογραφίες, η φύση, τα αντικείμενα, οι χώροι και ο ανθρώπινος μόχθος ήταν θέματα που απασχολούσαν τον βαν Γκογκ σ΄ όλη τη διάρκεια της πολυτάραχης ζωής του. Μιας ζωής σκληρής, γεμάτης κακουχίες και πόνους. Παρόλα αυτά, ήταν ένας άνθρωπος που έβλεπε πέρα από την εποχή του κι αυτό αναγνωρίστηκε μετά θάνατον μέσω των έργων του. Ένας άνθρωπος γεμάτος συναισθήματα και ρηξικέλευθες ιδέες. Όπως έλεγε και ο ίδιος στον αδερφό του Τέο - που είχαν εξαιρετικές σχέσεις - μέσω της συνεχούς τους αλληλογραφίας: «Τα μάτια μου είναι ακόμη κουρασμένα, αλλά έχω μία νέα ιδέα στο μυαλό μου και έχω το προσχέδιο του…1». Το πάθος του βαν Γκογκ για την τέχνη ήταν η αιτία αυτής της διαθεματικής, ομαδικής εργασίας, η οποία έγινε στο πλαίσιο της Ευέλικτης ζώνης και του μαθήματος των Εικαστικών, με δική μου πρωτοβουλία και την απαραίτητη συνεργασία του κύριου Χανιώτη Άγγελου (καθηγητή Εικαστικών) και των υπόλοιπων δασκάλων της Ε΄ Δημοτικού, Αυγουροπούλου Μαριάννας, Δέλγα Αναστασίας, Πετράκη Μαρκέλλας. Η ποιοτική έρευνα κράτησε τέσσερις διδακτικές ώρες και συνολικά τρεις εβδομάδες κι έγινε στη Γεννάδειο Σχολή, στον Άλιμο. Συμμετείχαν περίπου 80 μαθητές και κάθε τμήμα είχε διαφορετική θεματική ενότητα με βάση τα έργα τέχνης του καλλιτέχνη. Τα δεδομένα προέρχονται από τους 22 μαθητές του τμήματός μου.

Quantifying environment non-classicality in dissipative open quantum dynamics

Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Open quantum systems are inherently coupled to their environments, which in turn also obey quantum dynamical rules. By restricting to dissipative dynamics, here we propose a measure that quantifies how far the environment action on a system departs from the influence of classical noise fluctuations. It relies on the lack of commutativity between the initial reservoir state and the system-environment total Hamiltonian. Independently of the nature of the dissipative system evolution, Markovian or non-Markovian, the measure can be written in terms of the dual propagator that defines the evolution of system operators. The physical meaning and properties of the proposed definition are discussed in detail and also characterized through different paradigmatic dissipative Markovian and non-Markovian open quantum dynamics.

description: Digital preservation encompasses the theory and practice ensuring purposeful future use of digital resources. But how can one tell whether it has been effective or not? The evaluation of preservation efficacy has two dimensions: trustworthiness of managerial programs and systems; and successful use of managed resources. While the former has received extensive attention, the latter has been little investigated. This stems from an insufficiently broad conceptualization of the preservation enterprise, which should be viewed expansively as facilitating meaningful human communication across time and concomitant cultural distance. Communicological analysis leads to a semiotic- phenomenological model for preservation-enabled communication cognizant of the elusive nature of use, which is inherently contingent with respect to time, place, person, and purpose. Preservation success is positioned as an individual, rather than universal value, with a benchmark evaluation of situational verisimilitude, rather than absolute fidelity to an illusory canonical state and information experience. The proposed evaluative approach provides new conceptual clarity to preservation theory and practice, a more rigorous basis for illuminating the limits of preservation efficacy, and a more nuanced means of stating, measuring, and evaluating preservation intentions, expectations, and outcomes.

description: We investigate the transport properties of a Fermi-Hubbard chain with an impurity which is formed by a site with a periodically modulated chemical potential. We determine the momentum resolved transmission through this impurity in dependence of the modulation frequency and strength for a single particle and a pair of fermions. We find that the pair transmission has a very distinct behaviour from the single particle transmission. Different situations can occur, where only the single particle or the pair with a certain momentum are transmitted or filtered out.

Spike-Threshold Variability Originated from Separatrix-Crossing in Neuronal Dynamics

description: The threshold voltage for action potential generation is a key regulator of neuronal signal transduction, yet the mechanism of its dynamic variation is still not well described. In this paper, we propose that threshold phenomena can be classified as parameter thresholds and state thresholds. Voltage thresholds which belong to the state threshold are determined by the `general separatrix' in state space. We demonstrate that the separatrix generally exists in the state space of neuron models. The general form of separatrix was assumed as the function of both states and stimuli and the previously assumed threshold evolving equation versus time is naturally deduced from the separatrix. In terms of neuron dynamics, the threshold voltage variation, which is affected by different stimuli, is determined by crossing the separatrix at different points in state space. We suggest that the separatrix-crossing mechanism in state space is the intrinsic dynamic mechanism for threshold voltages and post-stimulus threshold phenomena. These proposals are also systematically verified in example models, three of which have analytic separatrices and one is the classic Hodgkin-Huxley model. The separatrix-crossing framework provides an overview of the neuronal threshold and will facilitate understanding of the nature of threshold variability.

description: The dynamics of interacting quantum many-body systems has two seemingly disparate but fundamental facets. The first is the dynamics of real-space local observables, and if and how they thermalise. The second is to interpret the dynamics of the many-body state as that of a fictitious particle on the underlying Hilbert-space graph. In this work, we derive an explicit connection between these two aspects of the dynamics. We show that the temporal decay of the autocorrelation in a disordered quantum spin chain is explicitly encoded in how the return probability on Hilbert space approaches its late-time saturation. As such, the latter has the same functional form in time as the decay of autocorrelations but with renormalised parameters. Our analytical treatment is rooted in an understanding of the morphology of the time-evolving state on the Hilbert-space graph, and corroborated by exact numerical results.

The Enactment Effect and Judgments of Learning: Action Memory Meets Metamemory
Creators: name: Jin, Andy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Research on metamemory has largely used only verbal materials. However, analogous to the
enactment effect in memory, metamemory accuracy has been shown to be different for subject-performed
tasks (SPTs), experimenter-performed tasks (EPTs), and verbal tasks (VTs). Prior
literature suggests that encoding differences create a strategic versus nonstrategic distinction that
influences both memory and metamemory. The present study uses a between-subjects encoding
manipulation (SPT vs. EPT vs. VT) to examine differences in judgments of learning (JOLs),
memory performance, and metamemory accuracy. JOLs and recall percentage did not vary
across condition, a result that is not unexpected due to the fact that such effects are commonly
observed within-subjects. Relative accuracy, as measured by gamma correlations, were not
significantly different from zero and also did not vary across conditions. Various explanations
for this result are discussed, emphasizing methodological and statistical differences between the
current study and prior research. Future implications for the study of metamemory and action
memory are considered.

Το επιμέρους μικρο-επίπεδο του σχολικού περιβάλλοντος δέχεται κι αυτό, με τη σειρά του, τις επιρροές, τις αφουγκράζεται, τις αφομοιώνει και τις ενσωματώνει στις δομές του. Η τεχνολογική επανάσταση που συντελείται παγκοσμίως δεν θα μπορούσε να μην επηρεάσει το σχολικό γίγνεσθαι και να μην επιφέρει αλλαγές στις σχολικές δομές. Η αλλαγή στον τρόπο επικοινωνίας μεταξύ των δημόσιων δομών με την ανάπτυξη της διαλειτουργικότητας μεταξύ των συστημάτων, οι αλλαγές στα εκπαιδευτικά προγράμματα, καθώς οι νέες μέθοδοι διδασκαλίας που έχουν στραφεί στην καλλιέργεια και στην ανάπτυξη δεξιοτήτων και ικανοτήτων, τόσο των μαθητών όσο και τον εκπαιδευτικών, φέρνουν στην επιφάνεια την ανάγκη επαναπροσδιορισμού των ρόλων, τόσο των εκπαιδευτικών όσο και των διευθυντών των σχολικών μονάδων. Οι δεύτεροι πλέον καλούνται να επαναξιολογήσουν τον ρόλο τους και να ενεργήσουν προς την κατεύθυνση της δημιουργίας εκείνων των συνθηκών, έτσι, ώστε οι σχολικές μονάδες να αποκτήσουν ψηφιακή κουλτούρα σε πολλαπλά επίπεδα.

Measurement of jet charge in dijet events from sqrt(s)=8 TeV pp collisions with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The momentum-weighted sum of the charges of tracks associated to a jet is sensitive to the charge of the initiating quark or gluon. This paper presents a measurement of the distribution of momentum-weighted sums, called jet charge, in dijet events using 20.3 fb$^{-1}$ of data recorded with the ATLAS detector at $\sqrt{s}=8$ TeV in $pp$ collisions at the LHC. The jet charge distribution is unfolded to remove distortions from detector effects and the resulting particle-level distribution is compared with several models. The $p_T$-dependence of the jet charge distribution average and standard deviation are compared to predictions obtained with several LO and NLO parton distribution functions. The data are also compared to different Monte Carlo simulations of QCD dijet production using various settings of the free parameters within these models. The chosen value of the strong coupling constant used to calculate gluon radiation is found to have a significant impact on the predicted jet charge. There is evidence for a $p_{T}$-dependence of the jet charge distribution for a given jet flavor. In agreement with perturbative QCD predictions, the data show that the average jet charge of quark-initiated jets decreases in magnitude as the energy of the jet increases.

description: Discrete time crystal is a class of nonequilibrium quantum systems exhibiting subharmonic responses to external periodic driving. Here we propose a class of discrete time crystals enforced by nonsymmorphic dynamical symmetry. We start with a system with nonsymmorphic dynamical symmetry, in which the instantaneous eigenstates become Möbius twisted, hence doubling the period of the instantaneous state. The exact solution of the time-dependent Schrödinger equation shows that the system spontaneously exhibits a period extension without undergoing quantum superposition states for a series of specifc evolution frequencies or in the limit of long evolution period. Moreover, in such case the system gains a π Berry phase after two periods' evolution. Finally, we show that the subharmonic response is stable even when many-body interactions are introduced, indicating a DTC phase in the thermodynamic limit.
