description: New developments in Thin Gap Chambers (TGC) detectors to provide fast trigger and high precision muon tracking under sLHC conditions are presented. The modified detectors are shown to stand a high total irradiation dose equivalent to 6 Coulomb/cm of wire, without showing any deterioration in their performance. Two large (1.2 x 0.8 m^2) prototypes containing four gaps, each gap providing pad, strips and wires readout, with a total thickness of 50 mm, have been constructed. Their local spatial resolution has been measured in a 100 GeV/c muon test beam at CERN. At perpendicular incidence angle, single gap position resolution better than 60 microns has been obtained. For incidence angle of 20 degrees resolution of less than 100 micron was achieved. TGC prototypes were also tested under a flux of 10^5 Hz/cm^2 of 5.5-6.5 MeV neutrons, showing a high efficiency for cosmic muons detection.

Tachu-luan, Shao-wu, Fukien (Fujian), China Material examined. China: Fukien (Fujian) Province, Ta-chu-laun, foot of Kuatun Mountain, 4500 feet, 1-5 May 1948, J. Fu, 2 ♂ (USNM). Adult habitus. Obscured by specimen condition but general color dark brown to black. Head black, pronotum black with pale lateral margins. Costal area of wings pale, contrasting with dark brown on rest of wing membrane. Antennae and legs dark brown to black. Male. Forewing length 15-16 mm. Tergum 10 bearing a pair of short, triangular spines positioned on either side of epiproct sclerite, and a pair of darkened, blunt projections on posterior margin above cercal bases (Fig. 20). Epiproct sclerite Y-shaped with short stem and truncate posterior margin. Paraprocts narrowly triangular with outer margins sclerotized and inner margins pale (Figs. 21); suture along base of paraprocts dark. Hammer transversely oval (Fig. 22). Aedeagus not everted, but apparently a membranous, multilobed, wide sac armed with microtrichia. Female. Unknown. Larva. Unknown. Remarks. The type material for this species is presumed lost or destroyed, and to our knowledge, no neotype has been proposed. Although these two males are in poor condition, they are apparently from a site very near the type locality and were taken in the same time frame as the holotype. Consequently, we regard these specimens as topotype representatives for this species known only from Fujian Province, China. Fresh material, including gravid females from the type locality would be highly desirable. In the absence of fresh material from the type locality, one of these specimens would be a suitable neotype.

description: This research examined the role of behavioural avoidance on excessive worry and applied a behavioural activation treatment to excessive worriers. The first study examined the latent construct of worry across adults from a university population (N: 536) with consideration of direct and indirect relationships with emotional distress, problem solving orientation, cognitive avoidance and behavioural avoidance. Path analysis from this model highlighted a central role for behavioural avoidance to facilitate distress in worry. Clinical implications for this study suggested that targeting behavioural avoidance in excessive worriers may benefit treatment outcome. In the second study, Behavioural Activation treatment was applied to seven excessive worriers. Treatment targeted behavioural avoidance e.g. procrastination, excessive checking of family members' safety, delay in checking exam results. Treatment strategies included functional analysis to break down avoidance patterns and ongoing activation of goal orientated behavioural steps. This seven- week group-based treatment intervention appeared to have transdiagnostic potential by producing reduced scores in excessive worry as well as depression and anxiety symptoms. 43% of participants demonstrated clinically significant change on the primary outcome of excessive worry and 57% no longer met criteria for GAD diagnosis at the end of treatment. The third study described a treatment trial of Behavioural Activation for Worry compared to a waitlist control. Treatment was delivered to 49 participants, in groups of six-eight individuals. Treatment sessions were extended to eight weeks. Twice as many individuals in the treatment group reported clinical significant reductions compared to the waitlist group at the end of the intervention. Significant improvements were also seen in life functioning and GAD symptoms. Results were maintained at four week follow-up. Regression results also demonstrated that reduction in behavioural avoidance was the best predictor of excessive worry four weeks after treatment completion, highlighting the key role of behavioural avoidance in the treatment of excessive worry.

description: The $f(R)$ gravity models formulated in Einstein conformal frame are equivalent to Einstein gravity together with a minimally coupled scalar field. The scalar field couples with the matter sector and the coupling term is given by the conformal factor.

description: This study explores the morphodynamic impact of groups of piers with different configurations (i.e., span characteristics, number of piers, and different reach locations) in a river cross section. It focuses on sandy low-land rivers presenting steady alternate bars and low Froude numbers. A 2DH (vertically integrated) numerical physics-based model (Delft3D) is used to simulate a straight channel, which is inspired from a Nile River reach in Egypt, downstream of the High Aswan Dam. The results show the formation of a forced bar upstream and downstream of the piers and increased deposition over the existing steady bars with different intensities. The nearest bars to the structures are the most affected ones. Large spans between bridge piers and more uniform pier distribution are found to decrease the deposition and its extension, hence reducing dredging investments for navigability
Catalytic hydroconversion of diphenylmethane with unsupported MoS2
Creators: name: Kukard, Ross S.
Publisher: name: University of British Columbia
Year: 2014

description: The mechanism by which hydroconversion catalysts promote residue conversion and coke suppression is unclear. Several theories are proposed in the literature but these have all been opposed, usually due to their lack of controlled mechanistic studies. A promising catalyst for residue hydroconversion is unsupported MoS₂. This catalyst is effective but expensive and deactivates during the reaction. Model compound studies were needed to elucidate the mechanism of MoS₂ catalysis in hydroconversion reactions, how this relates to residue hydroconversion and hence propose deactivation mechanisms and regeneration methodologies. Model compound screening in a commercially available stirred slurry-phase batch reactor identified diphenylmethane (DPM) as a suitable model reagent. Experiments were conducted at industrially applicable conditions of 445°C, 13.8 MPa H₂ and catalyst loadings of 0 - 1800 ppm Mo (introduced as Mo octoate which formed the MoS₂ active phase in-situ). Slow heat-up rates and wall catalysis, however, made this reactor unsuitable for detailed mechanistic studies. A novel mixed slurry-phase micro-reactor system was designed using externally applied vortex mixing and removable glass-inserts to allow for greater analytical resolution and determination of the thermocatalytic mechanism. Deactivated MoS₂ catalysts, as coke-catalyst agglomerates recovered from residue hydroconversion studies (Rezaei and Smith, 2013), were evaluated using the DPM testing methodology and a deactivation mechanism proposed. It was determined that the unsupported MoS₂ crystallites hydrogenate the DPM feed to cyclohexylmethylbenzene (CHMB) which undergoes thermolysis to short chain hydrocarbon radicals. These short chain radicals stabilise, by radical addition or radical disproportionation, other radicals in the system by a chain stabilisation reaction, itself promoted by catalytic hydrogenation (for instance of olefins formed during disproportionation). Deactivation of unsupported MoS₂ in residue hydroconversion was proposed to be due to the formation of an unreactive, porous carbonaceous structure upon which the otherwise unaltered catalyst particles become supported. The pores physically exclude larger species, such as asphaltenes, from reaching the active sites. Inter-recycle solvent extraction to remove coke precursors was proposed to inhibit deactivation in residue hydroconversion whilst mechanical and chemical size reduction were suggested for breaking the porous structure and re-exposing the MoS₂ crystallites.

description: The dynamics of a large number of liquids and polymers exhibit scaling properties characteristic of a simple repulsive inverse power law (IPL) potential, most notably the superpositioning of relaxation data as a function of the variable TVγ, where T is temperature, V the specific volume, and γ a material constant. A related scaling law, TmVmΓ, with the same exponent Γ=γ, links the melting temperature Tm and volume Vm of the model IPL liquid; liquid dynamics is then invariant at the melting point. Motivated by a similar invariance of dynamics experimentally observed at transitions of liquid crystals, we determine dynamic and melting point scaling exponents γ and Γ for a large number of non-associating liquids. Rigid, spherical molecules containing no polar bonds have Γ=γ; consequently, the reduced relaxation time, viscosity and diffusion coefficient are each constant along the melting line. For other liquids γ>Γ always; i.e., the dynamics is more sensitive to volume than is the melting point, and for these liquids the dynamics at the melting point slows down with increasing Tm (that is, increasing pressure).

description: We demonstrate two-stage laser stabilization based on a combination of Fabry- Perot and spectral-hole burning techniques. The laser is first pre-stabilized by the Fabry-Perot cavity to a fractional-frequency stability of sigma_y(tau) < 10^-13. A pattern of spectral holes written in the absorption spectrum of Eu3+:Y2SiO5 serves to further stabilize the laser to sigma_y(tau) = 6x10^-16 for 2 s < tau < 8 s. Measurements characterizing the frequency sensitivity of Eu3+:Y2SiO5 spectral holes to environmental perturbations suggest that they can be more frequency stable than Fabry-Perot cavities.

description: Compactification of 6d N=(2,0) theory of type G on a punctured Riemann surface has been effectively used to understand S-dualities of 4d N=2 theories. We can further introduce branch cuts on the Riemann surface across which the worldvolume fields are transformed by the discrete symmetries associated to those of the Dynkin diagram of type G. This allows us to generate more S-dualities, and in particular to reproduce a couple of S-dual pairs found previously by Argyres and Wittig.

description: Hemacroneuria Enderlein Hemacroneuria Enderlein, 1909:395. Type species, Hemacroneuria violacea Enderlein, 1909, gen. propr. This genus was placed in the synonymy of Kiotina by Klapálek (1916) and it remained there until Zwick (1973b) placed it as a synonym of Acroneuria. Uchida (1990) considered it a valid genus and possible member of the proposed tribe, but in the absence of publication of this opinion the genus has remained in the synonymy of Acroneuria. The genus is presently known from Vietnam. Hemacroneuria males are distinguished from Kiotina, Flavoperla and Gibosia by the presence of low knobs instead of triangular spines on tergum 10, and by the absence of a distinct epiproct sclerite on tergum 10.

Paraprocts broadly triangular but sharply pointed and incurved at tips. Aedeagus not fully everted, but membranous and covered with fine spines and microtrichia. Female. Forewing length 25 mm. Subgenital plate projecting over all or most of sternum 9; posterior margin notched (Fig. 36). Vagina membranous, slender without armature, similar to H. marginalis. Egg. Length ca. 0.40 mm, width ca. 0.34 mm. Outline oval to sub-spherical, collar a small, slightly projecting button (Figs. 37, 39). Chorion coarsely punctate throughout (Figs. 37-40); micropyles sessile, set on ridges surrounding chorionic punctations (Fig. 37). Larva. Unknown. Etymology. The patronym honors H. Malicky, collector of the holotype and numerous other interesting specimens from this region. Diagnosis. This species can be distinguished from H. marginalis (described below) on the basis of pronotal color pattern and by details of male tergum 10. In H. marginalis a membranous band divides tergum 10 along its entire length, whereas in H. malickyi the posterior area of tergum 10 is sclerotized. It can also be distinguished from H. violacea one the basis of the peg-like setae found on male tergum 10; these structures are absent in H. violacea.

description: The charge transfer in low energy (0.25 to 150 eV/amu) H($nl$) + He$^+(1s)$ collisions is investigated using a quasi-molecular approach for the $n=2,3$ as well as the first two $n=4$ singlet states. The diabatic potential energy curves of the HeH$^+$ molecular ion are obtained from the adiabatic potential energy curves and the non-adiabatic radial coupling matrix elements using a two-by-two diabatization method, and a time-dependent wave-packet approach is used to calculate the state-to-state cross sections. We find a strong dependence of the charge transfer cross section in the principal and orbital quantum numbers $n$ and $l$ of the initial or final state. We estimate the effect of the non-adiabatic rotational couplings, which is found to be important even at energies below 1 eV/amu. However, the effect is small on the total cross sections at energies below 10 eV/amu. We observe that to calculate charge transfer cross sections in a $n$ manifold, it is only necessary to include states with $n^{\prime}\leq n$, and we discuss the limitations of our approach as the number of states increases.

description: We propose a setup involving Majorana bound states (MBS) hosted by a vortex on a superconducting surface of a 3D Topological Insulator (TI). We consider a narrow channel drilled across a TI slab with both sides covered by s-wave superconductor. In the presence of a vortex pinned to such a channel, it acts as a ballistic nanowire connecting the superconducting surfaces, with a pair of MBS localized in it. The energies of the MBS possess a 4π-periodic dependence on the superconductive phase difference ϕbetween the surfaces. It results in the appearence of an anomalous term in the current-phase relation, I_a(ϕ) for the supercurrent flowing along the channel between the superconductive surfaces. We have calculated the shape of the 4π-periodic function I_a(ϕ), as well as the dependence of its amplitude on temperature and system parameters.

description: We report the results of a Suzaku observation of the anomalous X-ray pulsar (AXP) 1E 1841-045 at a center of the supernova remnant Kes 73. We confirmed that the energy-dependent spectral models obtained by the previous separate observations were also satisfied over a wide energy range from 0.4 to ~70 keV, simultaneously. Here, the models below ~10 keV were a combination of blackbody (BB) and power-law (PL) functions or of two BBs wit h different temperatures at 0.6 - 7.0 keV (Morii et al. 2003), and that above ~20 keV was a PL function (Kuiper Hermsen Mendez 2004). The combination BB + PL + PL was found to best represent the phase-averaged spectrum. Phase-resolved spectroscopy indicated the existence of two emission regions, one with a thermal and the other with a non-thermal nature. The combination BB + BB + PL was also found to represent the phase-averaged spectrum well. However, we found that this model is physically unacceptable due to an excessively large area of the emission region of the blackbody. Nonetheless, we found that the temperatures and radii of the two blackbody components showed moderate correlations in the phase-resolved spectra. The fact that the same correlations have been observed between the phase-averaged spectra of various magnetars (Nakagawa et al. 2009) suggests that a self-similar function can approximate the intrinsic energy spectra of magnetars below ~10 keV.

description: We study center vortex free energies and 't Hooft's electric fluxes on the lattice in 2+1 dimensions, where SU(2) for example, is in the universality class of the 2d Ising model. This places a wealth of exact results at our fingertips. In particular, spacelike center vortices in SU(2) near criticality correspond to spin interfaces in the 2d Ising model, whose universal scaling functions are known exactly. We exploit this to locate the deconfinement transition with unprecedented precision and subsequently for a finite size scaling analysis, where the self-duality of the $2d$ spin model is reflected in a duality between the spacelike vortices and confining electric fluxes. The corresponding relation between the string tension and its dual in the high temperature phase is arguably the simplest example of a universal amplitude ratio. Around the transition, both can be efficiently extracted from the exact results with a global one-parameter fit which allows straightforward continuum extrapolation.

description: There is a constant need for educators to develop and maintain effective up-to-date assessments. While there is a growing body of research in computing education on utilizing large language models (LLMs) in generation and engagement with coding exercises, the use of LLMs for generating programming MCQs has not been extensively explored. We analyzed the capability of GPT-4 to produce multiple-choice questions (MCQs) aligned with specific learning objectives (LOs) from Python programming classes in higher education. Specifically, we developed an LLM-powered (GPT-4) system for generation of MCQs from high-level course context and module-level LOs. We evaluated 651 LLM-generated and 449 human-crafted MCQs aligned to 246 LOs from 6 Python courses. We found that GPT-4 was capable of producing MCQs with clear language, a single correct choice, and high-quality distractors. We also observed that the generated MCQs appeared to be well-aligned with the LOs. Our findings can be leveraged by educators wishing to take advantage of the state-of-the-art generative models to support MCQ authoring efforts.

It features a new user interface, several new output formats including C++ process libraries for Pythia 8, and full compatibility with FeynRules for new physics models implementation, allowing for event generation for any model that can be written in the form of a Lagrangian. MadGraph 5 builds on the same philosophy as the previous versions, and its design allows it to be used as a collaborative platform where theoretical, phenomenological and simulation projects can be developed and then distributed to the high-energy community. We describe the ideas and the most important developments of the code and illustrate its capabilities through a few simple phenomenological examples.

description: Based on recent advances in first-principles theory, we develop a general model of the band offset at metal/ferroelectric interfaces. We show that, depending on the polarization of the film, a pathological regime might occur where the metallic carriers populate the energy bands of the insulator, making it metallic. As the most common approximations of density functional theory are affected by a systematic underestimation of the fundamental band gap of insulators, this scenario is likely to be an artifact of the simulation. We provide a number of rigorous criteria, together with extensive practical examples, to systematically identify this problematic situation in the calculated electronic and structural properties of ferroelectric systems. We discuss our findings in the context of earlier literature studies, where the issues described in this work have often been overlooked. We also discuss formal analogies to the physics of polarity compensation at LaAlO3/SrTiO3 interfaces, and suggest promising avenues for future research.

description: We show that by Ca-doping the Bi2Se3 topological insulator, the Fermi level can be fine tuned to fall inside the band gap and therefore suppress the bulk conductivity. Non-metallic Bi2Se3 crystals are obtained. On the other hand, the Bi2Se3 topological insulator can also be induced to become a bulk superconductor, with Tc ~ 3.8 K, by copper intercalation in the van der Waals gaps between the Bi2Se3 layers. Likewise, an as-grown crystal of metallic Bi2Te3 can be turned into a non-metallic crystal by slight variation of the Te content. The Bi2Te3 topological insulator shows small amounts of superconductivity with Tc ~ 5.5 K when reacted with Pd to form materials of the type PdxBi2Te3.
Conceptions of curricular integration in an undergraduate degree program : a case study in Pharmaceutical Sciences
Creators: name: Pearson, Marion Louise
Publisher: name: University of British Columbia
Year: 2014

description: This study examined conceptions of curricular integration held by actors in an undergraduate pharmacy program, and the relationship of those conceptions to observed integration in a curriculum espoused in program documents, enacted by instructors, and experienced by students. Points of convergence and divergence between the espoused, enacted, and experienced dimensions of the curriculum were also examined. The conceptual framework used was Hubball and Burt’s curriculum design model, with data collection and analysis further informed by Chinowsky’s practice implementation matrix. Qualitative case study methodology was employed, using the baccalaureate program of the Faculty of Pharmaceutical Sciences at the University of British Columbia as an instrumental case. Data sources included documents, such as curriculum planning records and course syllabi; classroom observations; interviews with curriculum planning leaders, course coordinators, and external stakeholders with supervisory roles as preceptors and employers; and focus group interviews with students. Findings suggested that individuals’ conceptions of curriculum integration related to their experiences and were uninformed by scholarship or theoretical models. Curriculum planning leaders’ and course coordinators’ understandings emphasized horizontal integration across disciplines, reflecting their experiences as disciplinary experts and teachers in a discipline-based curriculum with some multidisciplinary components. External stakeholders had little understanding of curricular integration, reflecting their minimal connection to the curriculum. Students co-constructed broader notions of curricular integration that included horizontal and vertical dimensions, reflecting their holistic experiences of the curriculum. Structural, content, and pedagogical strategies supported integration within the curriculum. Comparison of the espoused and enacted curriculum showed that intended structural and content aspects were implemented, while the pedagogical promise of the espoused curriculum was not fully realized in the enacted curriculum, with integrative pedagogies often missing. Although most curriculum planning leaders and course coordinators appeared satisfied with their efforts, students described missed opportunities for integration and expressed strong interest in integrative learning through arrangement of content by disease states rather than disciplines and by case-based teaching and assessment. Implications for curricular redesign in higher education include the need for effective curriculum leadership and scholarship, and attention to perspectives of key stakeholders, especially students, to ensure congruence between the espoused, enacted, and experienced curriculum.

description: LIRGs and ULIRGs are much more numerous at higher redshifts than locally, dominating the star-formation rate density at redshifts ~1 - 2. Therefore, they are important objects in order to understand how galaxies form and evolve through cosmic time. We aim to characterize the morphologies of the stellar continuum and the ionized gas (H_alpha) emissions from local sources, and investigate how they relate with the dynamical status and IR-luminosity of the sources. We use optical (5250 -- 7450 Å) integral field spectroscopic (IFS) data for a sample of 38 sources, taken with the VIMOS instrument, on the VLT. We present an atlas of IFS images of continuum emission, H_alpha emission, and H_alpha equivalent widths for the sample. The H_alpha images frequently reveal extended structures that are not visible in the continuum, such as HII regions in spiral arms, tidal tails, rings, of up to few kpc from the nuclear regions. The morphologies of the continuum and H_alpha images are studied on the basis of the C_{2kpc} parameter, which measures the concentration of the emission within the central 2 kpc. The C_{2kpc} values found for the H_alpha images are higher than those of the continuum for the majority (85%) of the objects in our sample. On the other hand, most of the objects in our sample (~62%) have more than half of their H_alpha emission outside the central 2 kpc. No clear trends are found between the values of C_{2kpc} and the IR-luminosity of the sources. On the other hand, our results suggest that the star formation in advance mergers and early-stage interactions is more concentrated than in isolated objects. We compared the H_alpha and infrared emissions as tracers of the star-formation activity. We find that the star-formation rates derived using the H_alpha luminosities generally underpredict those derived using the IR luminosities, even after accounting for reddening effects.

Calculation of Helium nuclei in quenched lattice QCD

description: We present results for the binding energies for ^4He and ^3He nuclei calculated in quenched lattice QCD at the lattice spacing of a =0.128 fm with a heavy quark mass corresponding to m_pi = 0.8 GeV. Enormous computational cost for the nucleus correlation functions is reduced by avoiding redundancy of equivalent contractions stemming from permutation symmetry of protons or neutrons in the nucleus and various other symmetries. To distinguish a bound state from an attractive scattering state, we investigate the volume dependence of the energy difference between the ground state energy of the nucleus channel and the free multi-nucleon states by changing the spatial extent of the lattice from 3.1 fm to 12.3 fm. A finite energy difference left in the infinite spatial volume limit leads to the conclusion that the measured ground states are bounded. It is also encouraging that the measured binding energies and the experimental ones show the same order of magnitude.

description: This research aims at investigating how ethical discourses are understood in technology-mediated assessment practices in English as a foreign language (EFL) writing programs in Indonesian private universities. This study investigates three private universities established by non-state foundations with diverse purposes. The findings present how policies frame teachers as assessment designers, communicative assessors, assessment motivators, data analysts and assessment surveillants mediating ethical discourses. The second findings chapter demonstrates how teachers operationalised, contested, and interpreted these complex state and institutional ethical expectations of assessment roles in practices. Finally, this study presents students’ perceptions of ethical discourses in technology-mediated assessment practices.

description: A disposable and low-cost pencil graphite electrode was activated by an electrochemical method and a novel metal nanoparticle-polymer nanocomposite film was fabricated and modified on its surface. The surface morphology and elemental composition of the electrodes were characterized by scanning electron microscopy. The modified electrode showed electrocatalytic ability toward NO oxidation and was applied for sensing. The electrochemical mechanism was characterized. The current corresponding to the oxidation peak increased linearly from 10 nmol/L to 5.7 µmol/L NO with a detection limit of 3.6 nmol/L at a signal-to-noise ratio equal to 3. The nanocomposite film electrode was successfully used to monitor NO released by murine neuroblastoma cells.

description: We report on the experimental observation of the quantum oscillations in microwave magnetoabsorption of a high-mobility two-dimensional electron gas induced by Landau quantization. Using original resonance-cavity technique, we observe two kinds of oscillations in the magnetoabsorption originating from inter-Landau-level and intra-Landau-level transitions. The experimental observations are in full accordance with theoretical predictions. Presented theory also explains why similar quantum oscillations are not observed in transmission and reflection experiments on high-mobility structures despite of very strong effect of microwaves on the dc resistance in the same samples.

description: This study performs BERT-based analysis, which is a representative contextualized language model, on corporate disclosure data to predict impending bankruptcies. Prior literature on bankruptcy prediction mainly focuses on developing more sophisticated prediction methodologies with financial variables. However, in our study, we focus on improving the quality of input dataset. Specifically, we employ BERT model to perform sentiment analysis on MD&A disclosures. We show that BERT outperforms dictionary-based predictions and Word2Vec-based predictions in terms of adjusted R-square in logistic regression, k-nearest neighbor (kNN-5), and linear kernel support vector machine (SVM). Further, instead of pre-training the BERT model from scratch, we apply self-learning with confidence-based filtering to corporate disclosure data (10-K). We achieve the accuracy rate of 91.56% and demonstrate that the domain adaptation procedure brings a significant improvement in prediction accuracy.
Entropy power inequality for a family of discrete random variables

description: It is known that the Entropy Power Inequality (EPI) always holds if the random variables have density. Not much work has been done to identify discrete distributions for which the inequality holds with the differential entropy replaced by the discrete entropy. Harremoës and Vignat showed that it holds for the pair (B(m,p), B(n,p)), m,n \in \mathbb{N}, (where B(n,p) is a Binomial distribution with n trials each with success probability p) for p = 0.5. In this paper, we considerably expand the set of Binomial distributions for which the inequality holds and, in particular, identify n_0(p) such that for all m,n \geq n_0(p), the EPI holds for (B(m,p), B(n,p)). We further show that the EPI holds for the discrete random variables that can be expressed as the sum of n independent identical distributed (IID) discrete random variables for large n.

Detecting Rumor Veracity with Only Textual Information by Double-Channel Structure

description: Kyle (1985) proposes two types of rumors: informed rumors which are based on some private information and uninformed rumors which are not based on any information (i.e. bluffing). Also, prior studies find that when people have credible source of information, they are likely to use a more confident textual tone in their spreading of rumors. Motivated by these theoretical findings, we propose a double-channel structure to determine the ex-ante veracity of rumors on social media. Our ultimate goal is to classify each rumor into true, false, or unverifiable category. We first assign each text into either certain (informed rumor) or uncertain (uninformed rumor) category. Then, we apply lie detection algorithm to informed rumors and thread-reply agreement detection algorithm to uninformed rumors. Using the dataset of SemEval 2019 Task 7, which requires ex-ante threefold classification (true, false, or unverifiable) of social media rumors, our model yields a macro-F1 score of 0.4027, outperforming all the baseline models and the second-place winner (Gorrell et al., 2019). Furthermore, we empirically validate that the double-channel structure outperforms single-channel structures which use either lie detection or agreement detection algorithm to all posts.

description: Let $\cT$ be Teichmüller space of a closed surface of genus at least 2. For any point $c\in \cT$, we describe an action of the circle on $\cT\times \cT$, which limits to the earthquake flow when one of the parameters goes to a measured lamination in the Thurston boundary of $\cT$. This circle action shares some of the main properties of the earthquake flow, for instance it satisfies an extension of Thurston's Earthquake Theorem and it has a complex extension which is analogous and limits to complex earthquakes. Moreover, a related circle action on $\cT\times \cT$ extends to the product of two copies of the universal Teichmüller space.
