description: Scripted dialogues such as movie and TV subtitles constitute a widespread source of training data for conversational NLP models. However, there are notable linguistic differences between these dialogues and spontaneous interactions, especially regarding the occurrence of communicative feedback such as backchannels, acknowledgments, or clarification requests. This paper presents a quantitative analysis of such feedback phenomena in both subtitles and spontaneous conversations. Based on conversational data spanning eight languages and multiple genres, we extract lexical statistics, classifications from a dialogue act tagger, expert annotations and labels derived from a fine-tuned Large Language Model (LLM). Our main empirical findings are that (1) communicative feedback is markedly less frequent in subtitles than in spontaneous dialogues and (2) subtitles contain a higher proportion of negative feedback. We also show that dialogues generated by standard LLMs lie much closer to scripted dialogues than spontaneous interactions in terms of communicative feedback.

description: We discuss new bounds on vectors coupled to currents whose non-conservation is due to mass terms, such as $U(1)_{L_μ- L_τ}$. Due to the emission of many final state longitudinally polarized gauge bosons, inclusive rates grow exponentially fast in energy, leading to constraints that are only logarithmically dependent on the symmetry breaking mass term. This exponential growth is unique to Stueckelberg theories and reverts back to polynomial growth at energies above the mass of the radial mode. We present bounds coming from the high transverse mass tail of mono-lepton+missing transverse energy events at the LHC, which beat out cosmological bounds to place the strongest limit on Stueckelberg $U(1)_{L_μ- L_τ}$ models for most masses below a keV. We also discuss a stronger, but much more uncertain, bound coming from the validity of perturbation theory at the LHC.

description: Detecting community structure is fundamental to clarify the link between structure and function in complex networks and is used for practical applications in many disciplines. A successful method relies on the optimization of a quantity called modularity [Newman and Girvan, Phys. Rev. E 69, 026113 (2004)], which is a quality index of a partition of a network into communities. We find that modularity optimization may fail to identify modules smaller than a scale which depends on the total number L of links of the network and on the degree of interconnectedness of the modules, even in cases where modules are unambiguously defined. The probability that a module conceals well-defined substructures is the highest if the number of links internal to the module is of the order of \sqrt{2L} or smaller. We discuss the practical consequences of this result by analyzing partitions obtained through modularity optimization in artificial and real networks.

description: It is a long-standing conjecture that any CFT with a large central charge and a large gap $Δ_{\text{gap}}$ in the spectrum of higher-spin single-trace operators must be dual to a local effective field theory in AdS. We prove a sharp form of this conjecture by deriving numerical bounds on bulk Wilson coefficients in terms of $Δ_{\text{gap}}$ using the conformal bootstrap. Our bounds exhibit the scaling in $Δ_{\text{gap}}$ expected from dimensional analysis in the bulk. Our main tools are dispersive sum rules that provide a dictionary between CFT dispersion relations and S-matrix dispersion relations in appropriate limits. This dictionary allows us to apply recently-developed flat-space methods to construct positive CFT functionals. We show how AdS$_{4}$ naturally resolves the infrared divergences present in 4D flat-space bounds. Our results imply the validity of twice-subtracted dispersion relations for any S-matrix arising from the flat-space limit of AdS/CFT.

description: Let $G$ be a complex Lie group and $ΛG$ denote the group of maps from the unit circle ${\mathbb S}^1$ into $G$, of a suitable class. A differentiable map $F$ from a manifold $M$ into $ΛG$, is said to be of \emph{connection order $(_a^b)$} if the Fourier expansion in the loop parameter $λ$ of the ${\mathbb S}^1$-family of Maurer-Cartan forms for $F$, namely $F_λ^{-1} \dd F_λ$, is of the form $\sum_{i=a}^b α_i λ^i$. Most integrable systems in geometry are associated to such a map. Roughly speaking, the DPW method used a Birkhoff type splitting to reduce a harmonic map into a symmetric space, which can be represented by a certain order $(_{-1}^1)$ map, into a pair of simpler maps of order $(_{-1}^{-1})$ and $(_1^1)$ respectively. Conversely, one could construct such a harmonic map from any pair of $(_{-1}^{-1})$ and $(_1^1)$ maps. This allowed a Weierstrass type description of harmonic maps into symmetric spaces. We extend this method to show that, for a large class of loop groups, a connection order $(_a^b)$ map, for $a<0

description: We report feedback cooling of translational and librational degrees of freedom of a levitated micromagnet cylinder, utilizing a piezoelectric actuator to apply linear feedback to high-Q mechanical modes. The normal modes are measured with a superconducting pick-up coil coupled to a DC SQUID, and phase information is fed back to the piezoelectric actuator to feedback cool a center-of-mass mode to $\sim$7 K, and a librational mode to $830 \pm 200$ mK. Q-factors of $1.0 \times 10^7$ are evaluated for the center-of-mass mode. We find that it is plausible to achieve ground state cooling of the center-of-mass mode by introducing vibration isolation, optimizing the geometry of the pick-up coil to focus on the specific mode of interest and utilizing a state-of-the-art SQUID for detection.

description: We investigate the effects of the adiabatic loading of optical lattices to the temperature by applying the mean-field approximation to the three-dimensional Bose-Hubbard model at finite temperatures. We compute the lattice-height dependence of the isentropic curves for the given initial temperatures in case of the homogeneous system i.e., neglecting the trapping potential. Taking the unit of temperatures as the recoil energy, the adiabatic cooling/heating through superfluid (SF) - normal (N) phase transition is clearly understood. It is found that the cooling occurs in SF phase while the heating occurs in N phase and the efficiency of adibatic cooling/heating is higher at higher temperatures. We also explain how its behavior can be understood from the lattice-hight dependence of dispersion relation in each phase. Furthermore, the connection of the adiabatic heating/cooling between the cases with/without the trapping potential is discussed.

The notion of language education can be defined by focussing on two aspects: the first one is the nature of language education, i.e., the voluntary act of helping a human faculty (the faculty of language, which is specific to homo loquens) emerge (the word ‘education’ derives from the Latin e ducere, ‘let out, let emerge’); the second one, the fields of language education in school systems, i.e. the teaching of the mother tongue (rather than ‘teaching’ other terms could be used, such as ‘perfectioning’, ‘developing metalinguistic awareness’, as the mother tongue has already been acquired when school starts), of modern languages (foreign languages for all students; second and ethnic or community languages, in some cases) and of classical languages (Greek, Latin, Arabic and so on).

description: We propose a simple and efficient real-space approach for the calculation of the ground-state energies of Wigner crystals in 1, 2, and 3 dimensions. To be precise, we calculate the first two terms in the asymptotic expansion of the total energy per electron which correspond to the classical energy and the harmonic correction due to the zero-point motion of the Wigner crystals, respectively. Our approach employs Clifford periodic boundary conditions to simulate the infinite electron gas and a renormalized distance to evaluate the Coulomb potential. This allows us to calculate the energies unambiguously and with a higher precision than those reported in the literature. Our results are in agreement with the literature values with the exception of harmonic correction of the 2-dimensional Wigner crystal for which we find a significant difference. Although we focus on the ground state, i.e., the triangular lattice and the body-centered cubic lattice, in two and three dimensions, respectively, we also report the classical energies of several other common lattice structures.

Generation of tools for real-time observation of neurodegenerative disease related cellular pathologies

Publisher: name: Macquarie University

description: Currently, the pathological biochemistry of Amyotrophic Lateral Sclerosis (ALS) is poorly understood resulting in limited treatment options. Emerging research has implicated aberrant stress granules in ALS pathology. Stress granules are accumulations of non-membrane bound RNA-protein assemblies which aggregate in the cytosol of cells as a natural response to external stimuli. These stress granule assemblies are a dynamic biological response to cellular stress, limiting mRNA translation initiation to help the cell survive short-term stresses such as thermal, metabolic, and oxidative stress. Chronic stress granules form when the cell does not disperse the RNA-protein assemblies leading to cell death. The objective of this thesis is to create models to study stress granule formation and disassembly in ALS in real time, in vivo. Zebrafish are the most suitable model organism for this study. Their high reproduction rate, a well characterised gene altering ‘toolkit’, and transparency in their embryonic and larval stages allow for a high number of samples to be genetically altered and screened over short time frames. Zebrafish share up to 70% of exons and major organs of interest with humans which should enable sound comparison at the cellular level of stress granule dynamics. To study stress granule formation, this project aims to link known stress granule associated proteins with fluorescent markers to visualise stress granule dynamics, in real time, in vivo, through confocal microscopy. In this thesis we have generated mRNA stress granule reporters. These mRNA stress granule reporters were injected into zebrafish embryos, allowing the visualisation of the formation of protein aggregates determined to be stress granules. These puncta were quantified and analysed with morphological assays to determine the effect on the zebrafish model. We have characterised and established the mVenus-G3bp1 mRNA transcript as a stress granule reporter and established direction for the future of this research.

description: Thanks to missions like Kepler and TESS, we now have access to tens of thousands of high precision, fast cadence, and long baseline stellar photometric observations. In principle, these light curves encode a vast amount of information about stellar variability and, in particular, about the distribution of starspots and other features on their surfaces. Unfortunately, the problem of inferring stellar surface properties from a rotational light curve is famously ill-posed, as it often does not admit a unique solution. Inference about the number, size, contrast, and location of spots can therefore depend very strongly on the assumptions of the model, the regularization scheme, or the prior. The goal of this paper is twofold: (1) to explore the various degeneracies affecting the stellar light curve "inversion" problem and their effect on what can and cannot be learned from a stellar surface given unresolved photometric measurements; and (2) to motivate ensemble analyses of the light curves of many stars at once as a powerful data-driven alternative to common priors adopted in the literature. We further derive novel results on the dependence of the null space on stellar inclination and limb darkening and show that single-band photometric measurements cannot uniquely constrain quantities like the total spot coverage without the use of strong priors. This is the first in a series of papers devoted to the development of novel algorithms and tools for the analysis of stellar light curves and spectral time series, with the explicit goal of enabling statistically robust inference about their surface properties.

New views of validity in language testing
Creators: name: D’Este, Claudia
Publisher: name: Università Ca’ Foscari Venezia, Italia

description:

Language testing has been defined as one of the core areas of applied linguistics because it tackles two of its fundamental issues: the need to define and reflect on the appropriateness of Second Language Acquisition models and constructs by data analysis from language tests and the importance of facing the ethical challenge deriving from the social and political role language tests play nowadays. Language testing has thus a twofold impact in a variety of contexts. In the first instance, it constitutes a scientific impulse for which research is needed to develop and implement the technical design of tests. Secondly, language testing has also become subject of debating because the use and interpretation of test results introduce ethical issues concerning the concept of ‘fairness’ in the construction, administration, evaluation and interpretation of language tests. In fact, language tests are always designed and used to make decisions on the basis of a process in which information about test takers is gathered from an observed performance under test conditions. This inevitably leads to the development of codes of ethics in educational testing environments and to the elaboration of theories of validity and validation.

description: This paper presents a framework addressing the challenge of global localization in autonomous mobile robotics by integrating LiDAR-based descriptors and Wi-Fi fingerprinting in a pre-mapped environment. This is motivated by the increasing demand for reliable localization in complex scenarios, such as urban areas or underground mines, requiring robust systems able to overcome limitations faced by traditional Global Navigation Satellite System (GNSS)-based localization methods. By leveraging the complementary strengths of LiDAR and Wi-Fi sensors used to generate predictions and evaluate the confidence of each prediction as an indicator of potential degradation, we propose a redundancy-based approach that enhances the system's overall robustness and accuracy. The proposed framework allows independent operation of the LiDAR and Wi-Fi sensors, ensuring system redundancy. By combining the predictions while considering their confidence levels, we achieve enhanced and consistent performance in localization tasks.

The effect of the CCI mutation on cell cycle morphogenesis in Paramecium Tetraurelia
Creators: name: Adl, Sina M.
Publisher: name: University of British Columbia
Year: 2008

description: The ccl mutant is temperature sensitive and arrests the cell cycle at 34.4° C. The transition point for division under restrictive conditions defines the point of commitment to division. We have examined the point of commitment to division in relation to the time course of stomatogenesis and micronuclear mitosis in both synchronous and asynchronous cell samples. Our analysis shows that stomatogenesis begins well before the point of commitment to division, which occurs at the 6-rowed oral primordium stage. At this stage micronuclei are in late anaphase. Oral morphogenesis is arrested up to this stage in mutant cells at the restrictive temperature, as are later stages of micronuclear division. These results are interesting because they suggest that micronuclear DNA synthesis and initiation of mitosis occur normally in ccl mutants, even though macronuclear DNA synthesis stops immediately on transfer to restrictive conditions. The meiotic cell cycles do not require the ccl function. This suggests that ccl is required exclusively for the vegetative cell cycle and not for micronuclear division or stomatogenesis during the sexual pathways.

description: We consider a hybrid wireless sensor network with regular and transmit-only sensors. The transmit-only sensors do not have receiver circuit, hence are cheaper and less energy consuming, but their transmissions cannot be coordinated. Regular sensors, also called cluster-heads, are responsible for receiving information from transmit-only sensors and forwarding it to sinks. The main goal of such a hybrid network is to reduce the cost of deployment while achieving some performance constraints (minimum coverage, sensing rate, etc). In this paper we are interested in the communication between transmit-only sensors and cluster-heads. We develop a detailed analytical model of the physical and MAC layer using tools from queuing theory and stochastic geometry. (The MAC model, that we call Erlang's loss model with interference, might be of independent interest as adequate for any non-slotted; i.e., unsynchronized, wireless communication channel.) We give an explicit formula for the frequency of successful packet reception by a cluster-head, given sensors' locations. We further define packet admission policies at a cluster-head, and we calculate the optimal policies for different performance criteria. Finally we show that the proposed hybrid network, using the optimal policies, can achieve substantial cost savings as compared to conventional architectures.

description: Abstract This paper makes an attempt to investigate John Locke’s point of view with respect to philosophy of language in a critical manner. John Locke was one of the most prominent philosophers in the seventeenth century who had great impacts on the philosophers in political philosophy, education, psychology, language, human knowledge, and western philosophy. This article is one of the first studies concerning John Locke regarding language and philosophy in Iran. Moreover, it is criticized in this research. Locke’s opinions in terms of philosophy of language are presented in eight principles which are completely defined in the paper. For example, nature of language is based on its function and meaning. Language function is related to communicating that means relations among thoughts. Words are signifiers. Thoughts are the elements including abstract layers. One’s idea cannot be understood by the others. The relation between words and their meanings is arbitrary. Words are not inherently meaningful.
Lingua e musicalità

description:

The elements of music and sonority anticipate, precede and accompany the development of language; they serve to mediate the process of integration between the self and the alter ego. The body of our musical heritage is integrated with the social genesis of thought, and it allows us to recognize the experiences and emotional states of other human beings. Pre-verbal musical input substitutes the initial lack of practice of language; after the explosion of speech in the child, it further enriches language skills. The perception and the production of sound, starting from the use of the voice, which precedes the appearance of linguistic patterns, stem from precocious cerebral structures which are activated by sounds produced by the caregiver. This acoustic, proto-linguistic dialogue between the couple mother-child serves to create an ideal container where both cognitive and emotional data is present, and where the motivational and natural epistemological urge in children is reinforced. Pre-natal sounds, vocalises, sound games of Child Directed Speech, nursery rhymes and finally the sharing of spoken language are the aspects of musicality linked to language and concurrent to the linguistic and interpersonal growth of the skills in children.

description: Quantum tomography has become an indispensable tool in order to compute the density matrix $ρ$ of quantum systems in Physics. Recently, it has further gained importance as a basic step to test entanglement and violation of Bell inequalities in High-Energy Particle Physics. In this work, we present the theoretical framework for reconstructing the helicity quantum initial state of a general scattering process. In particular, we perform an expansion of $ρ$ over the irreducible tensor operators $\{T^L_M\}$ and compute the corresponding coefficients uniquely by averaging, under properly chosen Wigner D-matrices weights, the angular distribution data of the final particles. Besides, we provide the explicit angular dependence of both the normalised differential cross section and the generalised production matrix $Γ$. Finally, we re-derive all our previous results from a quantum-information perspective using the Weyl-Wigner-Moyal formalism and we obtain in addition simple analytical expressions for the Wigner $P$ and $Q$ symbols.

description: The Coma cluster is the richest and most compact of the nearby clusters, yet there is growing evidence that its formation is still on-going. A sensitive probe of this evolution is the dynamics of intracluster stars, which are unbound from galaxies while the cluster forms, according to cosmological simulations. With a new multi-slit imaging spectroscopy technique pioneered at the 8.2 m Subaru telescope and FOCAS, we can now detect and measure the line-of-sight velocities of the intracluster planetary nebulae which are associated with the diffuse stellar population of stars, at 100 Mpc distance. We detect significant velocity substructures within a 6 arcmin diameter field, centred on the Coma X-ray cluster emission. One substructure ispresent at ~5000 km/s, probably from infall of a galaxy group, while the main intracluster stellar component moves at ~ 6500 km/s. Hence the ICPNs associated with the diffuse light at the position of the MSIS field are not bound to the nearby cD galaxy NGC 4874, whose radial velocity is ~ 700 km/s greater.

Short stories – Raccontare la vita
Creators: name: Cassone, Alberto
Publisher: name: Università Ca’ Foscari Venezia, Italia

description:

This article aims at showing a possible way of using short stories to effectively bring young non-English students of English Literature closer to the art of telling stories, enhancing their interest in literature and helping them develop an independent approach to it. Six short stories, for a total class time of 24 hours, have been selected from the works of Mark Twain, Saki, O. Henry, Edith Wharton, to be read by a Liceo Linguistico, Fourth Year. The main focus was not on literary analysis, nor on literary history and criticism, but on an authentic reading/listening experience. Although this work includes warm-ups and guided reading and understanding activities, the learners’ experience was made as independent as possible from ‘cultural interferences’ like, for example, the emphasis on ‘literary awareness’ (conscious knowledge of genres, of techniques etc.). In addition, the 25 students will be asked to write their own short stories (with the help of guidelines), seven of which to be told to the class after the end of the second phrase.

description: Based on recent studies regarding high-temperature (high-$T_c$) La-Y ternary hydrides (e.g., $P{\bar{1}}$-La$_2$YH$_{12}$, $Pm{\bar{3}}m$-LaYH$_{12}$, and $Pm{\bar{3}}m$-(La,Y)H$_{10}$ with a maximum $T_c \sim 253$ K), we examined the phase and structural stabilities of the (LaH$_6$)(YH$_6$)$_y$ series as high-$T_c$ ternary hydride compositions using a genetic algorithm and $\it ab$ $\it initio$ calculations. Our evaluation showed that the $Pm\bar{3}m$-LaYH$_{12}$ reported in the previous study was unstable during decomposition into $R\bar{3}c$-LaH$_{6}$ + $Im\bar{3}m$-YH$_{6}$. We also discovered new crystal structures, namely $Cmmm$-LaYH$_{12}$ ($y=1$), $R\bar{3}c$-LaYH$_{12}$ ($y=1$), $Cmmm$-LaY$_3$H$_{24}$ ($y=3$), and $R\bar{3}$-LaY$_3$H$_{24}$ ($y=3$), showing stability against such decomposition. While $R\bar{3}c$ ($y=1$) and $R\bar{3}$ ($y=3$) did not exhibit superconductivity owing to the extremely low density of states at the Fermi level, $Cmmm$ phases exhibited a $T_{c}$ of approximately 140~K at around 200~GPa owing to the extremely high electron--phonon coupling constant ($λ$ = 1.876 for LaYH$_{12}$). By the twice longer stacking for $Cmmm$-LaY$_3$H$_{24}$, the coupling constant increased owing to the chemical pressure of Y, leading to a slightly increased $T_{c}$.

description: Deep hashing has been intensively studied and successfully applied in large-scale image retrieval systems due to its efficiency and effectiveness. Recent studies have recognized that the existence of adversarial examples poses a security threat to deep hashing models, that is, adversarial vulnerability. Notably, it is challenging to efficiently distill reliable semantic representatives for deep hashing to guide adversarial learning, and thereby it hinders the enhancement of adversarial robustness of deep hashing-based retrieval models. Moreover, current researches on adversarial training for deep hashing are hard to be formalized into a unified minimax structure. In this paper, we explore Semantic-Aware Adversarial Training (SAAT) for improving the adversarial robustness of deep hashing models. Specifically, we conceive a discriminative mainstay features learning (DMFL) scheme to construct semantic representatives for guiding adversarial learning in deep hashing. Particularly, our DMFL with the strict theoretical guarantee is adaptively optimized in a discriminative learning manner, where both discriminative and semantic properties are jointly considered. Moreover, adversarial examples are fabricated by maximizing the Hamming distance between the hash codes of adversarial samples and mainstay features, the efficacy of which is validated in the adversarial attack trials. Further, we, for the first time, formulate the formalized adversarial training of deep hashing into a unified minimax optimization under the guidance of the generated mainstay codes. Extensive experiments on benchmark datasets show superb attack performance against the state-of-the-art algorithms, meanwhile, the proposed adversarial training can effectively eliminate adversarial perturbations for trustworthy deep hashing-based retrieval.

description: Damped Lyman-alpha systems (DLAs) and sub-DLAs seen toward background quasars provide the most detailed probes of elemental abundances. Somewhat paradoxically these measurements are more difficult at lower redshifts due to the atmospheric cut-off, and so a few years ago our group began a programme to study abundances at z < 1.5 in quasar absorbers. In this paper, we present new UVES observations of six additional quasar absorption line systems at z < 1.5, five of which are sub-DLAs. We find solar or above solar metallicity, as measured by the abundance of zinc, assumed not to be affected by dust, in two sub-DLAs: one, towards Q0138-0005 with [Zn/H]=+0.28 +/- 0.16; the other towards Q2335+1501 with [Zn/H]=+0.07 +/- 0.34. Relatively high metallicity was observed in another system: Q0123-0058 with [Zn/H]=-0.45 +/- 0.20. Only for the one DLA in our sample, in Q0449-1645, do we find a low metallicity, [Zn/H]=-0.96 +/- 0.08. We also note that in some of these systems large relative abundance variations from component to component are observed in Si, Mn, Cr and Zn.

description: Heat engines are key devices that convert thermal energy into usable energy. Strong thermoelectricity, at the basis of electrical heat engines, is present in superconducting spin tunnel barriers at cryogenic temperatures where conventional semiconducting or metallic technologies cease to work. Here we realize a superconducting spintronic heat engine consisting of a ferromagnetic insulator/superconductor/insulator/ferromagnet tunnel junction (EuS/Al/AlO$_x$/Co). The efficiency of the engine is quantified for bath temperatures ranging from 25 mK up to 800 mK, and at different load resistances. Moreover, we show that the sign of the generated thermoelectric voltage can be inverted according to the parallel or anti-parallel orientation of the two ferromagnetic layers, EuS and Co. This realizes a thermoelectric spin valve controlling the sign and strength of the Seebeck coefficient, thereby implementing a thermoelectric memory cell. We propose a theoretical model that allows describing the experimental data and predicts the engine efficiency for different device parameters.

description: The reporting and the analysis of current events around the globe has expanded from professional, editor-lead journalism all the way to citizen journalism. Nowadays, politicians and other key players enjoy direct access to their audiences through social media, bypassing the filters of official cables or traditional media. However, the multiple advantages of free speech and direct communication are dimmed by the misuse of media to spread inaccurate or misleading claims. These phenomena have led to the modern incarnation of the fact-checker -- a professional whose main aim is to examine claims using available evidence and to assess their veracity. As in other text forensics tasks, the amount of information available makes the work of the fact-checker more difficult. With this in mind, starting from the perspective of the professional fact-checker, we survey the available intelligent technologies that can support the human expert in the different steps of her fact-checking endeavor. These include identifying claims worth fact-checking, detecting relevant previously fact-checked claims, retrieving relevant evidence to fact-check a claim, and actually verifying a claim. In each case, we pay attention to the challenges in future work and the potential impact on real-world fact-checking.

description: In this paper we consider a general theory of k-inlation and find out, that it may be in strong coupling regime. We derive accurate conditions of classical description validity using unitarity bounds for this model. Next, we choose simple toy model of k-inflation and obtain the explicit condition, which guarantees that the generation of perturbations is performed in a controllable way, i.e the exit from the effective horizon occurs in the weak coupling regime. However, for the same toy model the corresponding experimental bounds on a non-linear parameter $f^{\text{equil}}_{\text{NL}}$ associated with non-Gaussianities of the curvature perturbation provide much stronger constraint than strong coupling absence condition. Nevertheless, for other known models of inflation this may not be the case. Generally, one should always check if classical description is legitimate for chosen models of inflation.
