Inter-tier Correspondence Theory
Creators: name: Wee, Lian-Hee
Publisher: name: No Publisher Supplied
Year: 2004

description: Inter-tier Correspondence Theory (ICT) is a theory of candidate structure. It is a response to phenomena in which both opaque and transparent derivational effects are simultaneously attested. The response that ICT provides rests upon the recognition that structural configurations are crucial in triggering alternations in the first place. By appealing to percolation, ICT assumes that each phonological output candidate is in fact a structural representation where non-terminal nodes reconstruct the information content of the constituent nodes. However, reconstruction may be imperfect. That outputs are structural is hardly novel, since GEN generates structures to given strings. Instead, it is the carriage of information in non-terminal nodes that is noteworthy. Under ICT, terminal nodes would be identical to the input string. Alternations no longer apply to strings but to constituencies as elements of the input string percolate upwards in their constituent structures. This is an important improvement because it directly addresses the fact that mere adjacency does not trigger alternation (many marked collocations are tolerated if the offending sequence are not within the same constituent). To be precise, GEN takes an input string and maps it to candidate structures of various percolative possibilities with the terminal nodes identical to the input string and non-terminal nodes corresponding to their subordinates in a multitude of ways. Thus, ICT directly captures the insights of the containment and correspondence approaches within optimality theory. There is nothing derivational about percolation when construed as correspondence between tiers. In fact, ICT views structural tiers as one would a multi-layered club sandwich. In making the sandwich, layers are ordered, but in eating, it hardly matters. The usefulness of ICT is illustrated through a study of tonological alternation patterns in Mandarin and Tianjin. These languages illustrate that simultaneous exhibition of any of 'feeding', 'bleeding', 'counterfeeding' and 'counterbleeding' effects, are really results of alternations applying to constituents as they grow in size (in other words, upward percolation). This dissertation studies Mandarin and Tianjin in detail, but ICT extends beyond that. To qualify ICT as a general theory for opacity, this work also takes glimpses at English, Tiberian Hebrew and Yokuts.

description: Deep hedging is a promising direction in quantitative finance, incorporating models and techniques from deep learning research. While giving excellent hedging strategies, models inherently requires careful treatment in designing architectures for neural networks. To mitigate such difficulties, we introduce SigFormer, a novel deep learning model that combines the power of path signatures and transformers to handle sequential data, particularly in cases with irregularities. Path signatures effectively capture complex data patterns, while transformers provide superior sequential attention. Our proposed model is empirically compared to existing methods on synthetic data, showcasing faster learning and enhanced robustness, especially in the presence of irregular underlying price data. Additionally, we validate our model performance through a real-world backtest on hedging the SP 500 index, demonstrating positive outcomes.

description: Self-determined living and participation in the community are fundamental human needs and rights that are highly valued in contemporary Western societies. However, they are still often denied to people with special needs. Mass media, on the one hand, influences the rights of people with special needs and on the other hand, reflects current social attitudes. The following paper examines how self-determination and participation of people with disabilities are portrayed in "The Peanut Butter Falcon" (Nilson/Schwartz 2019) - a road movie from the perspective of a young man with trisomy 21. In the theoretical part - after a conceptual introduction - the author elaborates on the CRPD, the Capability Approach according to Martha C. Nussbaum, the construction of social normality (Jürgen Link) and the cultural model of disability (Anne Waldschmidt). The movie analysis itself is based on the 3-level model according to Wolfgang Gast.

description: Contrary to the common approach of the general relativity, the author uses his invariant integral of physical mesomechanics to model and study the universe at the large scale of about 100 MPc in the Euclidian space. The flatness of the universe proven by numerous probes of the WMAP and PLANCK satellite missions necessitates this approach. From the invariant integral of cosmology, the interaction force of two point masses in the cosmic-gravitational field is derived. This force is proven to be a sum of two terms, the one being the Newtonian gravity and the other the repulsion force caused by the cosmological constant. Both terms make up the right-hand part of the evolution equation of the dynamic universe. Qualitatively in agreement with the FLRW and LCDM models, and WMAP and PLANCK mission data, the exact solution of this equation has provided the history of the early decelerating universe and the asymptotic description of the Big Bang, the expansion at an almost constant rate in the middle age, and the current stage of the accelerated expansion of the universe. The age of the universe is found to be equal to 12.3 billion years. It is shown that neutron stars become stable Black Holes when their masses are greater than 6.7Msun Then, it is assumed that the universe not only expands but also revolves, and the evolution equations of the revolving and expanding universe are advanced, with the cosmological constant being defined in terms of the angular velocity of the universe. A singular solution of these evolution equations has described the history of the revolving and expanding universe, at least, up to the age of about ten billion years. Orbital velocities of stars in the Milky Way are calculated to be about 250 km/s independent of the distance of stars from the galaxy center. Using the equation of the fractal dimension of the universe as a power-law fractal, the thickness of a disk-shaped universe is found. The graviton of minimum frequency is hypothesized to be the smallest elementary particle and the building block of everything.

description: The physical properties of the so-called Ostriker isothermal, non-rotating filament have been classically used as benchmark to interpret the stability of the filaments observed in nearby clouds. However, such static picture seems to contrast with the more dynamical state observed in different filaments. In order to explore the physical conditions of filaments under realistic conditions, in this work we theoretically investigate how the equilibrium structure of a filament changes in a rotating configuration. To do so, we solve the hydrostatic equilibrium equation assuming both uniform and differential rotations independently. We obtain a new set of equilibrium solutions for rotating and pressure truncated filaments. These new equilibrium solutions are found to present both radial and projected column density profiles shallower than their Ostriker-like counterparts. Moreover, and for rotational periods similar to those found in the observations, the centrifugal forces present in these filaments are also able to sustain large amounts of mass (larger than the mass attained by the Ostriker filament) without being necessary unstable. Our results indicate that further analysis on the physical state of star-forming filaments should take into account rotational effects as stabilizing agents against gravity

description: We consider fretting wear in an adhesive contact due to tangential oscillations of small amplitude. While both wear in non-adhesive contacts and adhesive contacts without wear have been studied in detail, there still have been no attempts to combine both approaches. In the present paper, we study the problem of wear in adhesive contacts under the simplified assumption, that the adhesive (attractive) stress is constant up to some critical distance h and vanishes beyond this range (the Dugdale approximation). In this approximation, the normal adhesive contact problem can be solved to a great extent analytically. In a series of previous works, it was shown that the worn shape due to fretting wear tends to some limiting shape which is determined solely by the solution of the normal contact problem. In the present paper, we exploit these ideas to derive the limiting shape of the worn body in an adhesive contact.

description: Clinical trials for retinitis pigmentosa (RP) likely require long follow-ups because of the slow progression of RP. Understanding patients’ attitudes toward participation in a long trial and their acceptability of strategies aimed at promoting retention/compliance is important for assessing feasibility and resource needs and optimizing trial design. A crowdsourcing survey to adult RP patients was administered on social media in 2020 July-November. Patient enthusiasm level of study participation, acceptability of attending clinic visits every 4–5 months for 45-months, tele-visits with doctors, and of receiving text messages for medication reminders and for reporting missed dosages were surveyed. Among the 1473 respondents, over 95% use email or a mobile phone and receive text messages; 1157 (79%) respondents were very/somewhat enthusiastic about participation, among them, 80.6% were “very willing” to attend clinic visits every 4–5 months for 45 months; 90.3% were “very willing” to have tele-visits; 64.7% and 77.1% were willing to receive text reminders to take medication and messages surveying missed doses, respectively. The youngest age group (18–30) (22.1%) and oldest age group (70+) (26.1%) compared to the 41–50 years age group (14%) and women (23.5%) compared to men (14.2%) were statistically significantly more likely not to report high willingness to participate in clinical visits for 45 months. A trial requiring 4-years of commitment is feasible although retention can be challenging. Strategies including supplementing in-clinic visits with tele-visits and frequent communications may facilitate retention. This study also demonstrates a methodology useful for planning clinical trials for chronic diseases.

description: We consider the static properties of periodic structures in weak random disorder. We apply a functional renormalization group approach (FRG) and a Gaussian variational method (GVM) to study their displacement correlations. We focus in particular on the effects of temperature and we compute explicitly the crossover length scales separating different regimes in the displacement correlation function. To do so using the FRG we introduce a functional form that approximate very accurately the flow of the disorder correlator at all scales. We compare the FRG and GVM results and find excellent agreement. We show that the FRG predicts in addition the existence of a third length scale associated with the screening of the disorder by thermal fluctuations and discuss a protocol to observe it.

description: Crack initiation from blunt V-notch borders in ductile Al 6061-T6 plates is investigated experimentally and theoretically under mixed mode I/II loading. Experimental observations with naked eye during loading indicated large plastic deformations around the notch tip at the onset of crack initiation, demonstrating large-scale yielding failure regime for the aluminum plates. To theoretically predict the experimentally obtained value of the maximum load that each plate could sustain, i.e. the load-carrying capacity, without performing elastic-plastic failure analyses, the equivalent material concept (EMC) is combined with a well-known brittle fracture criterion, namely the averaged strain energy density (ASED) criterion. It is shown that the combined EMC-ASED criterion could successfully predict the experimental results for various V-notch angles and radii.

description: Diabetes mellitus type 2 is often described as the global pandemic of the 21st century with India emerging as its capital. Microvascular complications such as retinopathy associated with diabetes are a serious world health problem, leading to the already existing burden of blindness. The aim of this study was to determine whether VEGF gene polymorphisms rs35569394 and rs699947 are associated with DR in North Indians. North Indian subjects, diabetic controls with no retinopathy (DR I, n = 51), subjects with diabetes with mild-moderate retinal changes (DR II, n = 50), and subjects with diabetes with severe retinopathy with/without retinal neovascularization (DR III, n = 55) were recruited for this study. Genotyping of the VEGF gene I/D polymorphism was done by PCR and C/A polymorphism by PCR-RFLP method. DD-genotype was 2.73 times over expressed among DR III category (p = .02; OR: 2.73; 95% CI: 1.20–6.19) as compared to DR I category among male subgroup. C-allele (rs699947) had 1.66-times more exposure among DR III as compared to DR I (C vs. A allele; p = .063; OR: 1.66; 95% CI: 0.97–2.84), probably due to high linkage disequilibrium between both the polymorphisms. Results of our study support the hypothesis that D-allele and DD-genotype of rs35569394 have deleterious effect on the progression of DR. C-allele had skewed frequency towards DR III subjects owing to strong linkage disequilibrium between C-allele (rs699947) and D-allele (rs35569394).

description: We investigate the influence of clock frequency on the success rate of a fault injection attack. In particular, we examine the success rate of voltage and electromagnetic fault attacks for varying clock frequencies. Using three different tests that cover different components of a System-on-Chip, we perform fault injection while its CPU operates at different clock frequencies. Our results show that the attack's success rate increases with an increase in clock frequency for both voltage and EM fault injection attacks. As the technology advances push the clock frequency further, these results can help assess the impact of fault injection attacks more accurately and develop appropriate countermeasures to address them.

description: The rate-regulation tradeoff, defined between two objective functions, one penalizing the packet rate and one the regulation cost, can express the fundamental performance bound of networked control systems. However, the characterization of the set of globally optimal solutions in this tradeoff for multi-dimensional Gauss-Markov processes has been an open problem. In the present article, we characterize a policy profile that belongs to this set without imposing any restrictions on the information structure or the policy structure. We prove that such a policy profile consists of a symmetric threshold triggering policy based on the value of information and a certainty-equivalent control policy based on a non-Gaussian linear estimator. These policies are deterministic and can be designed separately. Besides, we provide a global optimality analysis for the value of information $\text{VoI}_k$, a semantic metric that emerges from the rate-regulation tradeoff as the difference between the benefit and the cost of a data packet. We prove that it is globally optimal that a data packet containing sensory information at time $k$ be transmitted to the controller only if $\text{VoI}_k$ becomes nonnegative. These results have important implications in the areas of communication and control.

From that, we also explore how the regularity of the stable and unstable foliations implies smooth conjugacy inside a class of endomorphisms including, for instance, the ones with constant Jacobian. As a consequence, we have in this class a characterization of smooth conjugacy between special Anosov endomorphisms and their linearizations.

description: Conditional Normalizing Flows (CNFs) are flexible generative models capable of representing complicated distributions with high dimensionality and large interdimensional correlations, making them appealing for structured output learning. Their effectiveness in modelling multivariates spatio-temporal structured data has yet to be completely investigated. We propose MotionFlow as a novel normalizing flows approach that autoregressively conditions the output distributions on the spatio-temporal input features. It combines deterministic and stochastic representations with CNFs to create a probabilistic neural generative approach that can model the variability seen in high dimensional structured spatio-temporal data. We specifically propose to use conditional priors to factorize the latent space for the time dependent modeling. We also exploit the use of masked convolutions as autoregressive conditionals in CNFs. As a result, our method is able to define arbitrarily expressive output probability distributions under temporal dynamics in multivariate prediction tasks. We apply our method to different tasks, including trajectory prediction, motion prediction, time series forecasting, and binary segmentation, and demonstrate that our model is able to leverage normalizing flows to learn complicated time dependent conditional distributions.

description: Pb$_{0.77}$Sn$_{0.23}$Se is a novel alloy of two promising thermoelectric materials PbSe and SnSe that exhibits a temperature dependent band inversion below 300 K. Recent work has shown that this band inversion also coincides with a trivial to nontrivial topological phase transition. To understand how the properties critical to thermoelectric efficiency are affected by the band inversion, we measured the broadband optical response of Pb$_{0.77}$Sn$_{0.23}$Se as a function of temperature. We find clear optical evidence of the band inversion at $160\pm15$ K, and use the extended Drude model to accurately determine a $T^{3/2}$ dependence of the bulk carrier lifetime, associated with electron-acoustic phonon scattering. Due to the high bulk carrier doping level, no discriminating signatures of the topological surface states are found, although their presence cannot be excluded from our data.

description: By means of ab initio calculations we investigate the possibility of existence of a boron nitride (BN) porous two-dimensional nanosheet which is geometrically similar to the carbon allotrope known as biphenylene carbon. The proposed structure, which we called Inorganic Graphenylene (IGP), is formed spontaneously after selective dehydrogenation of the porous Boron Nitride (BN) structure proposed by Ding et al. We study the structural and electronic properties of both porous BN and IGP and it is shown that, by selective substitution of B and N atoms with carbon atoms in these structures, the band gap can be significantly reduced, changing their behavior from insulators to semiconductors, thus opening the possibility of band gap engineering for this class of two-dimensional materials.

description: The stochastic variability (flickering) of the nova-like system (subclass of cataclysmic variable) MV Lyr yields a complicated power density spectrum with four break frequencies. Scaringi et al. (2012) analysed high-cadence Kepler data of MV Lyr, taken almost continuously over 600 days, giving the unique opportunity to study multicomponent Power Density Spectra (PDS) over a wide frequency range. We modelled this variability with our statistical model based on disc angular momentum transport via discrete turbulent bodies with an exponential distribution of the dimension scale. Two different models were used, a full disc (developed from the white dwarf to the outer radius of ~10^10 cm) and a radially thin disc (a ring at a distance of ~10^10 cm from the white dwarf) that imitates an outer disc rim. We succeed in explaining the two lowest observed break frequencies assuming typical values for a disc radius of 0.5 and 0.9 times the primary Roche lobe and an alpha parameter of 0.1-0.4. The highest observed break frequency was also modelled, but with a rather small accretion disc with radius of 0.3 times the primary Roche lobe and a high alpha value of 0.9 consistent with previous findings by Scaringi (2014). Furthermore, the simulated light curves exhibit the typical linear rms-flux proportionality linear relation and the typical log-normal flux distribution. As the turbulent process is generating fluctuations in mass accretion that propagate through the disc, this confirms the general knowledge that the typical rms-flux relation is mainly generated by these fluctuations. In general a higher rms is generated by a larger amount of superposed flares which is compatible with a higher mass accretion rate expressed by a larger flux.

“Nothing Done!”: The Poet in Early Nineteenth-Century American Culture
Creators: name: Anderson, Jill E.
Publisher: name: No Publisher Supplied
Year: 2000

description: In this dissertation, I argue that early nineteenth-century American poets’ and readers’ interpretations of Romanticism shaped their understanding of the role poetry and its producers could play in a developing national culture. By examining the public careers and private sentiments of four male poets — William Cullen Bryant, Henry Wadsworth Longfellow, Edgar Allan Poe, and Jones Very — I analyze how each reconciled poetic vocation with the moral and economic obligations associated with the attainment of manhood. I locate these poets and their critics within specific historical discourses of aesthetic reception and production, focusing on the tensions and overlaps between Scottish Common-sense and Romantic aesthetic thought. Finally, I suggest that as a career objective the production of poetry paralleled rather than opposed the middle-class project of the “self-made man.” The effortful self-mastery urged upon young men by prescriptive writers was echoed in critics’ assessments of American poets’ works. Both the male poet and the self-made man operated within discourses which stressed imperatives — do, be, act — without specific objects. Yet, for aspiring poets, Romantic emphases on spontaneous composition and emotional expressiveness made deliberate craftsmanship irrelevant to poetic production. By identifying poetic production as spontaneous and as the highest form of disinterested intellectual labor, antebellum American critics and poets alike obscured the actual work involved in poetry writing. This erasure of conscious literary labor separated effort from its products, replacing a poet’s personal motives for writing poetry with the more nebulous goal of service, to be achieved through evidently inspired transcription than through purposeful composition. The title ‘poet’ suggested devotion to higher, more abstract goals, above mere commodity production. Each of these poets’ careers show how ambition compelled aspiring American poets to justify their work while disclaiming their individual hopes for their poetry and their reputations. Each poet promoted an understanding of poetic labor that demanded just such disclaimers. By underscoring the insubstantial and all but effortless nature of poetic composition itself, all four of these poets contributed to an enfeebled definition of the male poet — as a man who received impressions rather than produced them, and who observed rather than acted.

description: Conversational Machine Reading (CMR) requires answering a user's initial question through multi-turn dialogue interactions based on a given document. Although there exist many effective methods, they largely neglected the alignment between the document and the user-provided information, which significantly affects the intermediate decision-making and subsequent follow-up question generation. To address this issue, we propose a pipeline framework that (1) aligns the aforementioned two sides in an explicit way, (2)makes decisions using a lightweight many-to-many entailment reasoning module, and (3) directly generates follow-up questions based on the document and previously asked questions. Our proposed method achieves state-of-the-art in micro-accuracy and ranks the first place on the public leaderboard of the CMR benchmark dataset ShARC.

Using optical photometry from the CIDA Deep Survey of Orion, near IR photometry from the Visible and Infrared Survey Telescope for Astronomy and low resolution spectroscopy obtained with Hectospec at the MMT, we selected 1246 photometric candidates to low mass stars and brown dwarfs with estimated masses within $0.02 \lesssim M/M_\odot \lesssim 0.8$ and spectroscopically confirmed a sample of 77 low mass stars as new members of the cluster with a mean age of $\sim$7 Myr. We have obtained a system initial mass function of the group that can be well described by either a Kroupa power-law function with indices $α_3=-1.73\pm0.31$ and $α_2=0.68\pm0.41$ in the mass ranges $0.03\leq M/M_\odot\leq 0.08$ and $0.08\leq M/M_\odot\leq0.5$ respectively, or a Scalo log-normal function with coefficients $m_c=0.21^{+0.02}_{-0.02}$ and $σ=0.36\pm0.03$ in the mass range $0.03\leq M/M_\odot\leq0.8$. From the analysis of the spatial distribution of this numerous candidate sample, we have confirmed the East-West elongation of the 25 Orionis group observed in previous works, and rule out a possible southern extension of the group. We find that the spatial distributions of low mass stars and brown dwarfs in 25 Orionis are statistically indistinguishable. Finally, we found that the fraction of brown dwarfs showing IR excesses is higher than for low mass stars, supporting the scenario in which the evolution of circumstellar discs around the least massive objects could be more prolonged.

description: The superradiance phenomena of massive bosons and fermions in the Kerr spacetime are studied in the Bargmann-Wigner formulation. In case of bi-spinor, the four independent components spinors correspond to the four bosonic freedom: one scalar and three vectors uniquely. The consistent description of the Bargmann-Wigner equations between fermions and bosons shows that the superradiance of the type with positive energy $(0

description: We investigate the connections between order and algebra in the hereditary C*-subalgebra lattice $\mathcal{H}(A)$ and *-annihilator ortholattice $\mathscr{P}(A)^\perp$. In particular, we characterize $\vee$-distributive elements of $\mathcal{H}(A)$ as ideals, answering a 25 year old question, allowing the quantale structure of $\mathcal{H}(A)$ to be completely determined from its lattice structure. We also show that $\mathscr{P}(A)^\perp$ is separative, allowing for C*-algebra type decompositions which are completely consistent with the original von Neumann algebra type decompositions.

description: Binary neutron star (NS) mergers are among the most promising sources of gravitational waves (GWs), as well as candidate progenitors for short Gamma-Ray Bursts (SGRBs). Depending on the total initial mass of the system, and the NS equation of state (EOS), the post-merger phase can see a prompt collapse to a black hole, or the formation of a supramassive NS, or even a stable NS. In the case of post-merger NS (PMNS) formation, magnetic field amplification during the merger will produce a magnetar with a large induced mass quadrupole moment, and millisecond spin. If the timescale for orthogonalization of the magnetic symmetry axis with the spin axis is sufficiently short the NS will radiate its spin down energy primarily via GWs. Here we study this scenario for various outcomes of NS formation: we generalise the set of equilibrium states for a twisted torus magnetic configuration to include solutions that, at a fixed exterior dipole field, carry a larger magnetic energy reservoir; we hence compute their magnetic ellipticity and the strength of the expected GW signal as a function of the magnitude of the dipole and toroidal field. The relative number of GW detections from PMNSs and from binary NSs is a strong function of the NS equation of state (EOS), being higher (~ 1%) for the stiffest EOSs and negligibly small for the softest ones. For intermediate-stiffness EOSs, such as the n=4/7 polytrope recently used by Giacomazzo \& Perna or the GM1 used by Lasky et al., the relative fraction is ~0.3%; correspondingly we estimate a GW detection rate from stable PMNSs of ~ (0.1-1) yr$^{-1}$ with Advanced detectors, and of ~ (100-1000) yr$^{-1}$ with third generation detectors such as the Einstein Telescope. Measurement of such GW signal would provide strong constraints on the NS EOS and on the nature of the binary progenitors giving rise to SGRBs.

White dwarf evolutionary sequences for low-metallicity progenitors: The impact of third dredge-up

description: We present new white dwarf evolutionary sequences for low-metallicity progenitors. White dwarf sequences have been derived from full evolutionary calculations that take into account the entire history of progenitor stars, including the thermally-pulsing and the post-asymptotic giant branch phases. We show that for progenitor metallicities in the range 0.00003--0.001, and in the absence of carbon enrichment due to the occurrence of a third dredge-up episode, the resulting H envelope of the low-mass white dwarfs is thick enough to make stable H burning the most important energy source even at low luminosities. This has a significant impact on white dwarf cooling times. This result is independent of the adopted mass-loss rate during the thermally-pulsing and post-AGB phases, and the planetary nebulae stage. We conclude that in the absence of third dredge-up episodes, a significant part of the evolution of low-mass white dwarfs resulting from low-metallicity progenitors is dominated by stable H burning. Our study opens the possibility of using the observed white dwarf luminosity function of low-metallicity globular clusters to constrain the efficiency of third dredge up episodes during the thermally-pulsing AGB phase of low-metallicity progenitors.

description: The d-metal alloy Ni$_{1-x}$V$_{x}$ undergoes a quantum phase transition from a ferromagnetic ground state to a paramagnetic ground state as the vanadium concentration $x$ is increased. We present magnetization, ac-susceptibility and muon-spin relaxation data at several vanadium concentrations near the critical concentration $x_c \approx11.6%$ at which the onset of ferromagnetic order is suppressed to zero temperature. Below $x_c$, the muon data reveal a broad magnetic field distribution indicative of long-range ordered ferromagnetic state with spatial disorder. We show evidence of magnetic clusters in the ferromagnetic phase and close to the phase boundary in this disordered itinerant system as an important generic ingredient of a disordered quantum phase transition. In contrast, the temperature dependence of the magnetic susceptibility above $x_c$ is best described in terms of a magnetic quantum Griffiths phase with a power-law distribution of fluctuation rates of dynamic magnetic clusters. At the lowest temperatures, the onset of a short-range ordered cluster-glass phase is recognized by an increase in the muon depolarization in transverse fields and maxima in ac-susceptibility.
