description: The effect of multibody massless neutrino exchanges between neutrons inside a finite-size neutron star is studied. We use an effective Lagrangian, which incorporates the effect of the neutrons on the neutrinos. Following Schwinger, it is shown that the total interaction energy density is computed by comparing the zero point energy of the neutrino sea with and without the star. It has already been shown that in an infinite-size star the total energy due to neutrino exchange vanishes exactly. The opposite claim that massless neutrino exchange would produce a huge energy is due to an improper summation of an infrared-divergent quantity. The same vanishing of the total energy has been proved exactly in the case of a finite star in a one-dimensional toy model. Here we study the three-dimensional case. We first consider the effect of a sharp star border, assumed to be a plane. We find that there is a non- vanishing of the zero point energy density difference between the inside and the outside due to the refraction index at the border and the consequent non-penetrating waves. An analytical and numerical calculation for the case of a spherical star with a sharp border confirms that the preceding border effect is the dominant one. The total result is shown to be infrared-safe, thus confirming that there is no need to assume a neutrino mass. The ultraviolet cut-offs, which correspond in some sense to the matching of the effective theory with the exact one, are discussed. Finally the energy due to long distance neutrino exchange is of the order of $10^{-8} -- 10^{-13} GeV per neutron$, i.e. negligible with respect to the neutron mass density.

description: Superpositions of rotational states in polar molecules induce strong, long-range dipolar interactions. Here we extend the rotational coherence by nearly one order of magnitude to 8.7(6) ms in a dilute gas of polar $^{23}$Na$^{40}$K molecules in an optical trap. We demonstrate spin-decoupled magic trapping, which cancels first-order and reduces second-order differential light shifts. The latter is achieved with a dc electric field that decouples nuclear spin, rotation and trapping light field. We observe density-dependent coherence times, which can be explained by dipolar interactions in the bulk gas.

Synchronization of Integrate and Fire oscillators with global coupling

Year: 1996
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: In this article we study the behavior of globally coupled assemblies of a large number of Integrate and Fire oscillators with excitatory pulse-like interactions. On some simple models we show that the additive effects of pulses on the state of Integrate and Fire oscillators are sufficient for the synchronization of the relaxations of all the oscillators. This synchronization occurs in two forms depending on the system: either the oscillators evolve ``en bloc'' at the same phase and therefore relax together or the oscillators do not remain in phase but their relaxations occur always in stable avalanches. We prove that synchronization can occur independently of the convexity or concavity of the oscillators evolution function. Furthermore the presence of disorder, up to some level, is not only compatible with synchronization, but removes some possible degeneracy of identical systems and allows new mechanisms towards this state.

By observing the concentration-frequency dependence of vibrational modes, we identified the boundaries among rhombohedral, monoclinic, and tetragonal ferroelectric phases. The analysis of the spectra was made in the view of theory group analysis making possible the assignment of some modes for the monoclinic phase.

description: Keyphrases are crucial for searching and systematizing scholarly documents. Most current methods for keyphrase extraction are aimed at the extraction of the most significant words in the text. But in practice, the list of keyphrases often includes words that do not appear in the text explicitly. In this case, the list of keyphrases represents an abstractive summary of the source text. In this paper, we experiment with popular transformer-based models for abstractive text summarization using four benchmark datasets for keyphrase extraction. We compare the results obtained with the results of common unsupervised and supervised methods for keyphrase extraction. Our evaluation shows that summarization models are quite effective in generating keyphrases in the terms of the full-match F1-score and BERTScore. However, they produce a lot of words that are absent in the author's list of keyphrases, which makes summarization models ineffective in terms of ROUGE-1. We also investigate several ordering strategies to concatenate target keyphrases. The results showed that the choice of strategy affects the performance of keyphrase generation.

description: We analyze in detail supersymmetry breaking by compactification of the fifth dimension in M-theory in the compactification pattern $11d \to 5d \to 4d$ and find that a superpotential is generated for the complex fields coming from $5d$ hypermultiplets, namely the dilaton $S$ and the complex structure moduli. Using general arguments it is shown that these fields are always stabilized such that they don't contribute to supersymmetry breaking, which is completely saturated by the Kähler moduli coming from vector multiplets. It is shown that this mechanism is the strong-coupling analog of the Rohm-Witten quantization of the antisymmetric tensor field strength of string theories. The effect of a gaugino condensate on one of the boundaries is also considered.

description: The twentieth century is characterized by a particular transformation in Architecture. It moves away from its own secular logic based on the recognizability and identity of the constituent elements and becomes the result of an intellectual process built on archaeological logic, the Foucauldian discourse on the aforementioned. From the beginning to the end of the century, with different characteristics and results, it is possible to identify this matrix in the different dominant thoughts in the architecture either conceived and built.

description: The dissipative properties of spatially nonlocal conductors are investigated in the context of quantum friction acting on an atom moving above a macroscopic body. The focus is on an extended version of the hydrodynamic model for the bulk material's electromagnetic response. It is shown that the standard hydrodynamic description is inadequate for evaluating the frictional force since it completely neglects Landau damping. The extended version of the model contains a frequency-dependent compressibility factor for the Fermi liquid and qualitatively resolves this issue. For a quantitative assessment, these results are contrasted with those obtained for the more fundamental Boltzmann-Mermin model. Since the latter is technically involved, the simplicity of the extended hydrodynamic model allows for an easier analysis of the impact of nonlocality on quantum friction for other (planar) geometries. This is illustrated with an example involving a thin slab.

description: In the 1950s, in an important and innovative period of Milanese architecture, Enzo Paci dedicated about ten essays to architecture, deriving from his friendly relationships a real research on architectural thought. This article shows that he is elaborating a phenomenological and relational conception of the Lebenswelt: in this philosophical perspective, he considers the city as an ideal type in which a harmonious whole of relationships takes shape. The architecture is not mere structure, but the expression of a coexistence in free intentional relationships immersed in concrete life.

description: The article aims to demonstrate the influence of Antonio Banfi and Corrente in the Milanese architectural culture of the 1930s. Banfi’s teaching offered architects an opportunity to rethink the project in philosophical terms of reaction to the «crisis of culture and civilization» of the time, emphasizing the urgency of a more direct and intimately involved dialogue on the part of architects towards their models. The problem of the relationship between form and technique, nature and construction, freedom of design and moral sense then became central after the war.

Coupled mechanical resonators with broken Lorentz reciprocity for sensor applications

Year: 2019
Subjects: subject: Applied Physics (physics.app-ph)
subject: FOS: Physical sciences

description: Having simultaneously a high quality factor (i.e. a narrow resonant band) and a shorter interaction time between the resonating system and the external sources (i.e. a wide resonant band) is a desirable characteristic for mechanical resonators, which however has been regarded as contradictory. This has been known as the limit of Lorentz reciprocity. We explore a configuration to achieve this desired characteristic within the mechanical regime. The configuration consists of a pair of mechanical resonators coupled together through their connecting part. One of them is encapsulated in a vacuum environment, and the other is left in the normal ambient condition. Numerical model of this configuration shows clearly the advantages such as: (a), sensitivity to the change of resonant frequency is greatly improved (the product of bandwidth $Δω$ and the interaction time $Δt$ has increased at least two orders of magnitude); (b), the value of $Δω\cdot Δt$ can be adjusted through the coupling stiffness.

description: Despite improvements in global child health during the last three decades, under-five mortality rates remain significantly high in sub-Saharan Africa and Asia. Both regions did not achieve the MDG target of reducing under-five mortality rates by two thirds by 2015. The underlying causes of under-five mortality differ significantly between countries and between regions, which highlights the need to expand our understanding of the determinants of child health in developing countries. By comparing the two geographic regions of the world with the highest under-five mortality rates, we aim to identify differences between the determinants of under-five mortality in these regions. We analyse a large sample of DHS data sets consisting of 35 sub-Saharan African countries and 13 Asian countries from 1992 to 2016. Using a discrete-time survival model that takes advantage of a recently developed multilevel framework in a Bayesian setting, allowing for important non-linear effects and cluster specific heterogeneity. We find strong non-linear effects for the baseline hazard, the household size, the year of birth, and the mother’s BMI. We find considerable differences in determinants between Asian and sub-Saharan African countries. This highlights the necessity to expand our current knowledge of the underlying mechanisms, and helps to formulate policy advices.

Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2020

description: Place is defined by physical, social, and economic activities and processes. Understand- ing the complexity of socially constructed places is a fundamental question in geography, sociology, and many other social sciences. Meanwhile, the growing amount of user volunteered geographic information (VGI) leads us to study place through a new perspective. For instance, Flickr users report local activities in various geographic locations that capture individualistic experiences and impressions of the locations. Many previous studies utilizing non-textual VGI have focused primarily on analyzing geographical footprints of places, which separated place from its meaning. This dissertation argues that the textual part of VGI provides us with unprecedented opportunities for deriving patterns of place meanings on an individual level. More specifically, three research questions are pursued in this dissertation. First, how to quantify placeness (i.e., place identities) that has been traditionally studied via theoretical and qualitative methods? Second, as place being innately interconnected, how can we assess connections between places in networks so that we can apply network science to analyze complex connections between places? Third, as geo-textual data can also reveal social events, how to trace critical events across places using geo-textual data? In order to answer these research questions, this dissertation leverages advances in machine learning, natural language processing and network analysis techniques on geo- textual data. By doing so this dissertation is able to build foundations for geo-textual data analytics and thus providing a new lens to study places and the connections between them from the bottom up. Overall, this dissertation showcases an interdisciplinary effort in computational social science research that combines computational textual data analytics and social scientific theories including human geography and sociology.

The proof is based on a relation between the mod $2$ Aomoto complex and the transfer long exact sequence. Applying the above result to the icosidodecahedral arrangement ($16$ planes in the three dimensional space related to the icosidodecahedron), we conclude that the first homology of the Milnor fiber has non-trivial $2$-torsion.

description: Статья посвящена анализу античной риторики и ее влиянию на образование и воспитание добропорядочного гражданина. В предпринимаемом анализе античной риторики осуществляется ее реинтерпретация с позиций современной риторики, а известные риторические концепции софистов, Платона и Цицерона в свете представлений об античном просвещении как единстве воспитания, образования и человечности (παιδεία) позволяют обнаружить дополнительный эвристический потенциал для современных моделей воспитания гражданственности. Здесь для нас важна не публичная риторика как таковая эпохи Античности, сколько языковое искусство в его исполнении определенным человеком, это говорящий человек, греческий и римский муж, каким он предстает или должен предстать в понимании классиков Античности. В данной работе софистическая риторика самоутверждения противостоит риторике привилегированного знания Платона как конкурирующие парадигмы образования и воспитания добропорядочного гражданина, а римская риторика оратора как совершенного гражданина предстает как исторически первая модель преодоления обозначенного противоречия. Наша задача — не примирение софистики и платонизма средствами современной риторики, однако, если это привносит новый импульс в застарелую философскую и риторическую проблему, то почему бы и не посмотреть на возможный эвристический потенциал ее реинтерпретации.

The measured splitting from the ground state to the excited triplet M_S=0 sublevel is Delta_1=24.2cm^-1 and the other two triplet state sublevels in zero magnetic field are 1.4cm^-1 below and above the M_S=0 sublevel. Another multiplet is at Delta_2=37.6cm^-1 from the ground state. A strong electric dipole active transition polarized in the (ab)-plane is activated in the dimer spin system below 15K at 52cm^-1.

Volumetric star formation laws of disc galaxies

description: Star formation (SF) laws are fundamental relations between the gas content of a galaxy and its star formation rate (SFR) and play key roles in galaxy evolution models. In this paper, we present new empirical SF laws of disc galaxies based on volume densities. Following the assumption of hydrostatic equilibrium, we calculated the radial growth of the thickness of the gaseous discs in the combined gravitational potential of dark matter, stars, and gas for 12 nearby star-forming galaxies. This allowed us to convert the observed surface densities of gas and SFR into the deprojected volume densities. We found a tight correlation with slope in the range 1.3-1.9 between the volume densities of gas (HI+H$_2$) and the SFR with a significantly smaller scatter than the surface-based (Kennicutt) law and no change in the slope over five orders of magnitude. This indicates that taking into account the radial increase of the thickness of galaxy discs is crucial to reconstruct their three-dimensional density profiles, in particular in their outskirts. Moreover, our result suggests that the break in the slope seen in the Kennicutt law is due to disc flaring rather than to a drop of the SF efficiency at low surface densities. Surprisingly, we discovered an unexpected correlation between the volume densities of HI and SFR, indicating that the atomic gas is a good tracer of the cold star-forming gas, especially in low density HI-dominated environments.

Sequential unsharp measurement of photon polarization

Subjects: subject: Quantum Physics (quant-ph)

description: We propose a general experimental scheme based on binary trees of partially polarizing beam splitters (PPBSs) for realizing sequential unsharp measurements of photon polarization. The sharpnesses and the bases of the particular photon polarization measurements can be chosen arbitrarily by using corresponding PPBSs and phase plates in the setup. In the limit of low sharpnesses the scheme can realize sequential weak measurements, too. We develop a general formalism for describing sequential unsharp measurements of photon polarization in which the particular unsharp measurements are characterized by appropriate measurement operators. We show that a straightforward experimental realization of this model is the proposed scheme. In this formalism the output polarization states after the sequential measurement and any correlation functions characterizing the measurement results can be easily calculated. Our model can be used for analyzing the consequences of applying postselection and reselection in the measurement. We derive the anomalous mean value for an unsharp polarization measurement with postselection and the anomalous second-order correlation function for the sequential unsharp measurement of photon polarization with reselection. We show that these anomalies can be easily measured using the proposed scheme.

The form factors are calculated from QCD sum rules on the light-cone including contributions up to twist 4, radiative corrections to the leading twist contribution and SU(3)-breaking effects. The theoretical uncertainty is estimated to be \sim 15%. The heavy-quark-limit relations between semileptonic and penguin form factors are found to be valid in the full accessible range of momentum transfer.

description: Στην παρούσα εργασία πραγματοποιήθηκε μια θεωρητική προσέγγιση της λειτουργίας της εφοδιαστικής αλυσίδας, των κινδύνων που απορρέουν από μια αλυσίδα εφοδιασμού και των τρόπων που δύναται αυτή να ανταπεξέλθει σε συνθήκες αβεβαιότητας, με τ που κυριαρχεί σήμερα. Πιο συγκεκριμένα πραγματοποιήθηκε έρευνα σε ξενόγλωσση και ελληνόγλωσση βιβλιογραφία, ηλεκτρονικές πηγές και διάφορες άλλες επιστημονικές εργασίες, ώστε να παρατεθούν οι έννοιες και οι ορισμοί της εφοδιαστικής αλυσίδας, της διαχείρισης της εφοδιαστικής αλυσίδας (supply chain management), των κινδύνων και της αβεβαιότητας που παρατηρούνται στα δίκτυα εφοδιασμού. Επιπρόσθετα, δόθηκε έμφαση στην κατηγοριοποίηση των κινδύνων και στα είδη αβεβαιότητας που εμφανίζονται κατά τη λειτουργία μιας εφοδιαστικής αλυσίδας, ούτως ώστε να διερευνηθούν οι πρακτικές αποτελεσματικής αντιμετώπισης των προκλήσεων που απορρέουν από τους κινδύνους και τις πηγές αβεβαιότητας από φορείς, οργανισμούς και επιχειρήσεις. Στην παρούσα εργασία δόθηκε ιδιαίτερη έμφαση στις διαταραχές που προκαλούνται σε μια αλυσίδα εφοδιασμού που περιλαμβάνει θαλάσσιες μεταφορές, μέσω των οποίων διακινείται το 90% του όγκου του διεθνούς εμπορίου, αποτελώντας τον οικονομικότερο τρόπο μεταφοράς εμπορευματοκιβωτίων και διευκολύνοντας την ανάπτυξη της διεθνούς οικονομίας και του παγκόσμιου εμπορίου. Ο κλάδος του διεθνούς εμπορίου και η ναυτιλία ήρθαν αντιμέτωπες με πρωτόγνωρες συνθήκες και προβλήματα στις εφοδιαστικές τους αλυσίδες, τα οποία συνοψίζονται σε τεράστιες καθυστερήσεις, κλείσιμο λιμένων, μείωση ζήτησης, χρεοκοπία εμπορικών και ναυτιλιακών επιχειρήσεων, επιβράδυνση στην ανάπτυξη του διεθνούς εμπορίου, μείωση τζίρου, προβλήματα που προέκυψαν από τους κινδύνους και το κλίμα αβεβαιότητας που επικρατούσαν την περίοδο της πανδημίας, την περίοδο κλεισίματος του περάσματος στο Σουέζ και κατά τη διάρκεια των πολεμικών συγκρούσεων μεταξύ Ρωσίας και Ουκρανίας. Οι προαναφερόμενες δυσμενείς συνθήκες τόνισαν την ανάγκη για εκ νέου σχεδιασμό των εφοδιαστικών αλυσίδων, με μεγαλύτερη ανθεκτικότητα και ευελιξία και την ανάγκη υιοθέτησης στρατηγικών ανάκαμψης για την αντιμετώπιση δυνητικών προκλήσεων στο άμεσο μέλλον στις παγκόσμιες εφοδιαστικές αλυσίδες.

description: Six-dimensional quantum dynamical calculations of the scattering of H_2 from a Pd(100) surface using a potential energy surface derived from density-functional theory calculations are presented. Due to the corrugation and anisotropy of the PES strong off-specular and rotationally inelastic diffraction is found. The dependence of the diffraction intensitities on the incident kinetic energy is closely examined. In particular we focus on the quantum oscillations for normal and off-normal incidence.

description: Gravitational collapse in cosmological context produces an intricate cosmic web of voids, walls, filaments and nodes. The anisotropic nature of collisionless collapse leads to the emergence of an anisotropic velocity dispersion, or stress, that absorbs most of the kinetic energy after shell-crossing. In this paper, we measure this large-scale velocity dispersion tensor $σ^2_{ij}$ in $N$-body simulations using the phase-space interpolation technique. We study the environmental dependence of the amplitude and anisotropy of the velocity dispersion tensor field, and measure its spatial correlation and alignment. The anisotropy of $σ^2_{ij}$ naturally encodes the collapse history and thus leads to a parameter-free identification of the four dynamically distinct cosmic web components. We find this purely dynamical classification to be in good agreement with some of the existing classification methods. In particular, we demonstrate that $σ^2_{ij}$ is well aligned with the large-scale tidal field. We further investigate the influence of small scale density fluctuations on the large scale velocity dispersion, and find that the measured amplitude and alignments are dominated by the largest perturbations and thus remain largely unaffected. We anticipate that these results will give important new insight into the anisotropic nature of gravitational collapse on large scales, and the emergence of anisotropic stress in the cosmic web.

description: Unsupervised text classification, with its most common form being sentiment analysis, used to be performed by counting words in a text that were stored in a lexicon, which assigns each word to one class or as a neutral word. In recent years, these lexicon-based methods fell out of favor and were replaced by computationally demanding fine-tuning techniques for encoder-only models such as BERT and zero-shot classification using decoder-only models such as GPT-4. In this paper, we propose an alternative approach: Lex2Sent, which provides improvement over classic lexicon methods but does not require any GPU or external hardware. To classify texts, we train embedding models to determine the distances between document embeddings and the embeddings of the parts of a suitable lexicon. We employ resampling, which results in a bagging effect, boosting the performance of the classification. We show that our model outperforms lexica and provides a basis for a high performing few-shot fine-tuning approach in the task of binary sentiment analysis.

description: Topological data analysis can reveal higher-order structure beyond pairwise connections between vertices in complex networks. We present a new method based on discrete Morse theory to study topological properties of unweighted and undirected networks using persistent homology. Leveraging on the features of discrete Morse theory, our method not only captures the topology of the clique complex of such graphs via the concept of critical simplices, but also achieves close to the theoretical minimum number of critical simplices in several analyzed model and real networks. This leads to a reduced filtration scheme based on the subsequence of the corresponding critical weights, thereby leading to a significant increase in computational efficiency. We have employed our filtration scheme to explore the persistent homology of several model and real-world networks. In particular, we show that our method can detect differences in the higher-order structure of networks, and the corresponding persistence diagrams can be used to distinguish between different model networks. In summary, our method based on discrete Morse theory further increases the applicability of persistent homology to investigate the global topology of complex networks.

description: When vegetation structure is altered, songbird communities may be affected. Despite speculation that African Elephant (Loxodonta africana) browsing impacts bird communities, existing data are limited. I sampled the bird communities of the Albany Thicket Biome at 10 sites in the Eastern Cape, South Africa, half with elephants and half without. Songbird community parameters were best predicted by how long elephants had been present, elephant density and the percentage cover of thicket vegetation. The sites where elephants had been present for longer had more bird species and increased songbird density and diversity. However, bird density also increased with increasing thicket vegetation cover and this is a phenomenon unlikely to be compatible with long-term elephant presence. There was an almost equal split between the number of bird species that appeared to be negatively affected by changes in habitat structure (47%) and those which benefited (53%). Smaller birds were generally more abundant as vegetation structural integrity increased and larger birds were more abundant when vegetation structural integrity declined. The browsing of elephants could be viewed as facilitative for songbirds in the short term. However, this effect may not persist in the long term because all elephant populations (notorious tree-fellers) in the Eastern Cape are found in fenced areas where natural migration is not possible. More broadly, my data provide important insight into how avian communities respond to habitat transformation at the local and regional scales.

description: We study the problem of baryon stability in M theory, starting from realistic four-dimensional string models constructed using the free-fermion formulation of the weakly-coupled heterotic string. Suitable variants of these models manifest an enhanced custodial gauge symmetry that forbids to all orders the appearance of dangerous dimension-five baryon-decay operators. We exhibit the underlying geometric (bosonic) interpretation of these models, which have a $Z_2 \times Z_2$ orbifold structure similar, but not identical, to the class of Calabi-Yau threefold compactifications of M and F theory investigated by Voisin and Borcea. A related generalization of their work may provide a solution to the problem of proton stability in M theory.
