description: We present work in a model used to describe semi-inclusive deep inelastic scattering off the deuteron. The model uses the virtual nucleon approximation to describe the interaction of the photon with the bound neutron and the generalized eikonal approximation is applied to calculate the final-state interaction diagram. Comparison with data taken at Jefferson Lab shows good agreement in the covered range of kinematics and points at a largely suppressed off-shell rescattering amplitude. The $W$ and $Q^2$ dependences of the total cross section and slope factor of the interaction of DIS products, $X$, off the spectator nucleon are extracted. Starting from the JLab data and our model calculations, we outline and apply an extrapolation method to obtain the neutron structure function $F_{2N}$ at high Bjorken $x$.

Uma Reflexão a Respeito da Evolução Humana e a Natureza da Linguagem
Creators: name: Pereira Jr., Alfredo
Publisher: name: abstracta
Year: 2021

description: In this paper I discuss scientific and philosophical issues related to the interdisciplinary area of Neurolinguistics, focusing on the origin and nature of human language. What kind of evolutionary process leads to the emergence of language? I propose that this process began with the adoption of bipedalism, triggering the co-evolution of new brain structures and forms of social organization. This process created a context that favoured the emergence of articulated vocalization using a combinatorial linguistic system. The identification of sufficient conditions for the emergence of human language in this context depends on the paradigm adopted for the analysis. I look for a synthesis of nativist and constructivist paradigms, showing that both contribute to an understanding of the origin and nature of human language.

Dewey's Metaphysics of Mind
Creators: name: Mendonça, Wilson
Publisher: name: abstracta
Year: 2021

description: In Experience and Nature Dewey makes “an attempt to contribute to what has come to be called an ‘emergent’ theory of mind”. On a first approach, that doesn’t look very innovative to our contemporary materialist convictions. Indeed, Kim argues persuasively that a central claim of emergentism—concerning the irreducibility of emergent properties—is irremediably at odds with a view of mental causation that follows from some very plausible physicalist assumptions. This is “the problem of downward causation.” I intend to show that Dewey’s brand of emergentism actually allows an adequate reply to the very important worry formulated by Kim.

Foundational Evidentialism and the Problem of Scatter
Creators: name: Poston, Ted
Publisher: name: abstracta
Year: 2021

description: This paper addresses the scatter problem for foundational evidentialism. Reflection on the scatter problem uncovers significant epistemological lessons. The scatter problem is evaluated in connection with Ernest Sosa’s use of the problem as an argument against foundational evidentialism. Sosa’s strategy is to consider a strong intuition in favor of internalism—the new evil demon problem, and then illustrate how a foundational evidentialist account of the new evil demon problem succumbs to the scatter problem. The goal in this paper is to evaluate the force of the scatter problem. The main argument of the paper is that the scatter problem has mixed success. On the one hand, scatter undermines objectual evidentialism, an evidentialist theory that formulates principles of basic perceptual justification in terms of the objects (or properties) ofperceptual states. On the other hand, the problem of scatter does not undermine content evidentialism, an evidentialist view that formulates its epistemic principles in terms of the assertive content of perceptual states. The significance of the scatter problem, especially in concert with the new evil demon problem, is that it provides an argument for content evidentialism.

Brain and Behavioral Functions Supporting the Intentionality of Mental States
Creators: name: De F. Teixeira, João
name: Pereira Jr., Alfredo
Publisher: name: abstracta
Year: 2021

description: This paper relates intentionality, a central feature of human consciousness, with brain functions controlling adaptive action. Mental intentionality, understood as the “aboutness” of mental states, includes two modalities: semantic intentionality, the attribution of meaning to mental states, and projective intentionality, the projection of conscious content into the world. We claim that both modalities are the evolutionary product of self-organized action, and discuss examples of animal behavior that illustrate some stages of this evolution. The adaptive advantages of self-organized action impacted on brain organization, leading to the formation of mammalian brain circuits that incorporate semantic intentionality in their modus operandi. Following the same line of reasoning, we suggest that projective intentionality could be explained as a result of habituation processes referenced to the dynamical interface of the body with the environment.

Rules, Games, and Society
Creators: name: Bertman, Martin A.
Publisher: name: abstracta
Year: 2021

description: ‘Game’ means ‘play within the construction of rules’. The sub-category ‘sport’ considers play as competition (in classical Greek, ‘athletos’ means ‘competition for the sake of victory’) where the rules are known to the audience, under the following divide: fundamental constructive rules about the game's structure and less important or flexible rules facilitating and monitoring play. These provide athletes and audience with stable knowledge. The excitement of play comes from the vagaries of the actual engagement of the rules in the action of play. The social order can use this as a metaphor of its ideal of civil law (and less sharply, of cultural custom) in relation to the citizen.

description: It is well known that the 2D XY model exhibits an unusual infinite order phase transition belonging to the Kosterlitz-Thouless (KT) universality class. Introduction of a nematic coupling into the XY Hamiltonian leads to an additional phase transition in the Ising universality class [D.H. Lee and G. Grinstein, Phys. Rev. Lett. 55, 541 (1985)]. Using a combination of extensive Monte Carlo simulations and finite size scaling, we show that the higher order harmonics lead to a qualitatively different phase diagram, with additional ordered phases originating from the competition between the ferromagnetic and pseudonematic couplings. The new phase transitions belong to the 2D Potts, Ising, or KT universality classes.

Causal Inheritance and Second-order Properties

description: We defend Jaegwon Kim’s ‘causal inheritance’ principle from an objection raised by Jurgen Schröder. The objection is that the principle is inconsistent with a view about mental properties assumed by Kim, namely, that they are second-order properties. We argue that Schröder misconstrues the notion of second-order property. We distinguish three notions of second-order property and highlight their problems and virtues. Finally, we examine the consequence of Kim’s principle and discuss the issue of whether Kim’s ‘supervenience argument’ generalizes to all special sciences or not.

description: Theoretical models of galaxy formation predict that galaxies acquire most of their baryons via cold mode accretion. Observations of high-redshift galaxies, while showing ubiquitous outflows, have so far not revealed convincing traces of the predicted cold streams, which has been interpreted as a challenge for the current models. Using high-resolution, zoom-in smooth particle hydrodynamics simulations of Lyman break galaxy (LBG) halos combined with ionizing radiative transfer, we quantify the covering factor of the cold streams at z=2-4. We focus specifically on Lyman limit systems (LLSs) and damped Ly-alpha absorbers (DLAs), which can be probed by absorption spectroscopy using a background galaxy or quasar sightline, and which are closely related to low-ionization metal absorbers. We show that the covering factor of these systems is relatively small and decreases with time. At z=2, the covering factor of DLAs within the virial radius of the simulated galaxies is ~3% (~1% within twice this projected distance), and arises principally from the galaxy itself. The corresponding values for LLSs are ~10% and ~4%. Because of their small covering factor compared to the order unity covering fraction expected for galactic winds, the cold streams are naturally dominated by outflows in stacked spectra. We conclude that the existing observations are consistent with the predictions of cold mode accretion, and outline promising kinematic and chemical diagnostics to separate out the signatures of galactic accretion and feedback.

Reconsidering the Epistemology of Deductive-Inferential Validity
Creators: name: Demont, Florian
Publisher: name: abstracta
Year: 2021

description: Until quite recently, the epistemology of logical laws has not been much discussed and neither has how one can be justified in claiming that a particular inference is valid. The transfer of warrant from premises to conclusion(s) in modus ponens will be examined in the paper through assessing Paul Boghossian's inferentialist proposal of assuming 'blind reasoning'. It will be argued that merely being justified in inferring according to a logical law a priori is worthless un-less one can also be justified in claiming that the inference is valid. An alternative to Boghossian's solution will be presented which addresses this need as well as the needs Boghossian had iden-tified previously.

Publisher: name: F1000 Research Limited
Year: 2019

description: Objective: The purpose of this study was to validate the use of stainless steel thermal desorption (TD) tubes containing 5 angstrom (Å) molecular sieve sorbent for passive sampling of nitrous oxide () during short exposures (<30 minutes) of up to 1000 ppm.  Validation will determine the passive uptake rate of  and whether the method meets accuracy of +25% required by the Occupational Safety and Health Administration (OSHA) and National Institutes of Occupational Safety and Health (NIOSH).

Methods: The method validation followed protocol set forth by OSHA for the development of industrial hygiene sampling and analytical methods.  A dynamic flow exposure chamber coupled with an HCS-501 flow, temperature, and humidity control system was utilized to create  concentrations ranging between 5 -1000 ppm and relative humidity of up to 80%.  Tube exposure times ranged from 10 to 75 minutes.  Exposed tubes were analyzed using gas chromatography/mass spectrometry to determine the mass of  collected during the sampling period.  Specific tests investigated the uptake rate, accuracy and precision, breakthrough volume, reverse diffusion, desorption efficiency, humidity effects, maximum sampling time, and effects of storage.

Results: Data collection is ongoing.  Analytical results will be described in this section when data collection is complete.

Conclusion: It is believed that 5Å molecular sieve TD tubes can be utilized for sampling durations of <30 minutes while meeting accuracy of + 25% with good precision.  This, in combination with the fact that TD methods avoid inherent dilution effects associated with conventional passive badges, would indicate that 5Å TD tubes could offer a potential alternative for passive sampling of .
Efficient layout-aware statistical analysis for photonic integrated circuits
Creators: name: Jhoja, Jaspreet Singh
Publisher: name: University of British Columbia
Year: 2021

description: Fabrication variability significantly impacts the performance of photonic integrated circuits (PICS), which makes it crucial to quantify the impact of fabrication variations at the design and simulation stage. The variability analysis enables circuit and system designers to optimize their designs to be more robust and obtain maximum yield when designing for manufacturing. The variability analysis requires a total of six parameters to model spatially correlated manufacturing variations in photonic circuits: mean, standard deviation, and correlation length for both width and thickness variations of photonic components. The correlation lengths are spatial parameters that describe how the width and thickness variations are distributed along a chip’s or a wafer’s surface. The methods that allow for the non-invasive characterization of variations are limited to extracting mean and standard deviations of width and thickness variations. In this thesis, we present a method to extract the physical correlation lengths, which are crucial to model manufacturing variations. In this thesis, we also present the Reduced Spatial Correlation Matrix based Monte Carlo (RSCM-MC), a methodology to study the impact of spatially correlated manufacturing variations on the performance of photonic circuits. The presented methodology is compared with another layout-dependent Monte Carlo (MC) simulation methodology, called Virtual Wafer-based Monte Carlo (VW-MC). First, we describe the process of generating spatially correlated physical variations using the presented methodology and use the generated correlated physical variations to conduct MC simulations. We then use a Mach-Zehnder lattice filter photonic circuit as a benchmark circuit to study the accuracy of the proposed method. We compare the statistical parameters of quantities defining the flatness of the transmission spectra of the filter. We then compare the computation performance of RSCM-MC with VW-MC using a combination of a small-sized circuit (two-stage Mach-Zehnder filter) and a large circuit (a 16x16 ring matrix) with thousands of components. For the best case, i.e. the small-sized circuit, we observe a decrease in computational times by 98.9% and a reduction in memory requirement by 72%. For the worst case, i.e. the 16x16 ring matrix, we observe a decrease in computational times by 99.8% and a reduction in memory requirement by 87%.

Testimony, Transmition, and Safety
Creators: name: Horvath, Joachim
Publisher: name: abstracta
Year: 2021

description: Most philosophers believe that testimony is not a fundamental source of knowledge, but merely a way to transmit already existing knowledge. However, Jennifer Lackey has presented some counterexamples which show that one can actually come to know something through testimony that no one ever knew before. Yet, the intuitive idea can be preserved by the weaker claim that someone in a knowledge-constituting testimonial chain has to have access to some non-testimo-nial source of knowledge with regard to what is testified. But even this weaker claim has a counterexample which I develop in close connection with a safety-account of knowledge. Thus, testimonial statements can sometimes enable us to know something for which none of our infor-mants has any source of knowledge available. I conclude that my counterexample nevertheless does not affect the core of our intuitions about testimony, although it establishes that testimony can indeed be a fundamental source of knowledge.

title: DEPRECATED: A CONVERSATIONAL SKILLS APPROACH TO PERSONAL RECONSTRUCTION : LONGITUDINAL STUDIES USING THE REPERTORY GRID
Creators: name: REID, FRASER
Publisher: name: University of Plymouth
Year: 1976

description: The aim of this research is to develop a range of procedures for enhancing conversational skills. From a review of theoretical analyses of social encounters a model of conversational process is developed to describe mechanisms by which interactants construct, maintain and revise cognitive models of their social environment. From this model, three dimensions of conversational competence are derived and a training paradigm devised incorporating the process of cognitive reflection by which functional properties of models are displayed to interactants. This paradigm provides a rationale for discrete intervention strategies to effect changes on each dimension of competence. Preliminary studies report attempts to implement the first intervention strategy in a friendship relationship and workshop group. Using the "conversational cycle" and repertory grid techniques, procedures are developed to exhibit critical interpersonal events and their relationship to modelling processes. The main studies investigate the second and third intervention strategies by developing serial repertory grid methods to exhibit the functional properties of centrality to self-cognition and stability of construction. The training paradigm is elaborated to include these properties at three levels of organisation, and a sequential Bayesian analysis is developed to determine the extent of centrality and stability of construction. The training paradigm is tested in two case-studies and evidence of increases in insight, centrality and elaboration of personal construction are found. This methodology is extended to incorporate repertory grids produced by two interactants yoked by element sample and tested in a case-study of a married couple. Evidence of increased insight and self-partner reconstruction is found, but predictions concerning increased self-partner distinctiveness are contraindicated. These findings suggest that evaluative criteria may not be coincident with subjective strategies, and alternative evaluation methodologies are proposed.

Skepticism, Externalism and Inference to the Best Explanation
Creators: name: Briesen, Jochen
Publisher: name: abstracta
Year: 2021

description: This paper focuses on a combination of the antiskeptical strategies offered by semantic externalism and the inference to the best explanation. I argue that the most difficult problems of the two strategies can be solved, if the strategies are combined: The strategy offered by semantic externalism is successful against standard skeptical brain-in-a-vat arguments. But the strategy is ineffective, if the skeptical argument is referring to the recent-envatment scenario. However, by focusing on the scenario of recent envatment the most difficult problems of the antiskeptical strategy posed by the inference to the best explanation can be solved. The most difficult problems with this strategy are: (1) Why is an explanation of our experience offered by the skeptical hypothesis more complex than our standard explanation? (2) Why is the more complex explanation less likely to be true? By focussing on the recent envatment hypothesis both questions can be answered satisfactorily. Therefore, the combination of semantic externalism and the inference to the best explanation yields to a powerful antiskeptical argument.

Development of lab-on-a-chip acoustofluidic platform with a potential application in extracellular vesicles purification
Creators: name: Taatizadeh, Erfan
Publisher: name: University of British Columbia
Year: 2021

description: Extracellular vesicles (EVs) play an important role in intercellular communication, as they are responsible for the transportation of proteins from their cells of origin to other locations within the body. They are found in a variety of bodily fluids and have proven to be promising candidates for the early diagnosis of different types of diseases. To use EVs as diagnostic tools their purification is a prerequisite step. Traditional methods of EV purification are time-consuming and expensive and can lead to morphology disruptions due to high induced shear stress. To address these problems, novel lab-on-a-chip-based purification methods have been employed. Among various methods introduced for separation and purification of EVs, cells, and synthetics microparticles, acoustofluidics (i.e., a combination of microfluidics and acoustics) has been one of the most effective methods. Unlike common separation techniques carried out in clinical laboratories that are based on chemical properties, the acoustofluidic process relies on the physical properties of the sample. Using acoustofluidics, the manipulation of cells and microparticles can be achieved in a label-free, contact-free, and highly biocompatible manner. This thesis reviews two types of acoustofluidic platforms which work based on parallel standing surface acoustic wave (pSSAW) and tilted standing surface acoustic wave (tSSAW). pSSAW is mainly used for microparticle alignments while tSSAW is implemented for microparticle separation based on particle size differences. In order to optimize the functionality of the aforementioned platforms, a two-dimensional numerical simulation has been established in this thesis. Such a model has subsequently followed by an experimental test using the pSSAW method. The numerical simulation is used to investigate the effects of the platform geometrical and operational conditions on the separation efficiency. Next, the optimal values are tested in an experimental setting to validate the optimal parameters and conditions. A similar experimental approach is applied to design and test the tSSAW platform although numerical simulation cannot be developed as such geometry requires three-dimensional modeling which is computationally expensive. Using the tSSAW chip, a separation efficiency of > 90% is demonstrated for the separation of 0.6 μm microparticles from 15 μm and 20 μm microparticles by adjusting the operational conditions.
Low-lying even parity meson resonances and spin-flavor symmetry

description: A study is presented of the $s-$wave meson-meson interactions involving members of the $ρ-$nonet and of the $π-$octet. The starting point is an SU(6) spin-flavor extension of the SU(3) flavor Weinberg-Tomozawa Lagrangian. SU(6) symmetry breaking terms are then included to account for the physical meson masses and decay constants, while preserving partial conservation of the axial current in the light pseudoscalar sector. Next, the $T-$matrix amplitudes are obtained by solving the Bethe Salpeter equation in coupled-channel with the kernel built from the above interactions. The poles found on the first and second Riemann sheets of the amplitudes are identified with their possible Particle Data Group (PDG) counterparts. It is shown that most of the low-lying even parity PDG meson resonances, specially in the $J^P=0^+$ and $1^+$ sectors, can be classified according to multiplets of the spin-flavor symmetry group SU(6). The $f_0(1500)$, $f_1(1420)$ and some $0^+(2^{++})$ resonances cannot be accommodated within this SU(6) scheme and thus they would be clear candidates to be glueballs or hybrids. Finally, we predict the existence of five exotic resonances ($I \ge 3/2$ and/or $|Y|=2$) with masses in the range 1.4--1.6 GeV, which would complete the $27_1$, $10_3$, and $10_3^*$ multiplets of SU(3)$\otimes$SU(2).

description: The paper proposes a method for solving the protein folding problem using deep reinforcement learning. A mathematical model of physical processes during the folding of hydrophobic-hydrophilic (HP-model) protein has been created. The results of solving the optimization problem are obtained, which show both quantitatively close to the optimal solution methods of protein folding, and qualitatively justified by biochemical and biophysical theory.
Amorphous silicon under mechanical shear deformations: shear velocity and temperature effects

description: Mechanical shear deformations lead, in some cases, to effects similar to those resulting from ion irradiation. Here we characterize the effects of shear velocity and temperature on amorphous silicon (\aSi) modelled using classical molecular dynamics simulations based on the empirical Environment Dependent Inter-atomic Potential (EDIP). With increasing shear velocity at low temperature, we find a systematic increase in the internal strain leading to the rapid appearance of structural defects (5-fold coordinated atoms). The impacts of externally applied strain can be almost fully compensated by increasing the temperature, allowing the system to respond more rapidly to the deformation. In particular, we find opposite power-law relations between the temperature and the shear velocity and the deformation energy. The spatial distribution of defects is also found to strongly depend on temperature and strain velocity. For low temperature or high shear velocity, defects are concentrated in a few atomic layers near the center of the cell while, with increasing temperature or decreasing shear velocity, they spread slowly throughout the full simulation cell. This complex behavior can be related to the structure of the energy landscape and the existence of a continuous energy-barrier distribution.

description: Rare-earth platinum bismuth (RPtBi) has been recently proposed to be a potential topological insulator. In this paper we present measurements of the metallic surface electronic structure in three members of this family, using angle resolved photoemission spectroscopy (ARPES). Our data shows clear spin-orbit splitting of the surface bands and the Kramers' degeneracy of spins at the Gamma and M points, which is nicely reproduced with our full-potential augmented plane wave calculation for a surface electronic state. No direct indication of topologically non-trivial behavior is detected, except for a weak Fermi crossing detected in close vicinity to the Gamma point, making the total number of Fermi crossings odd. In the surface band calculation, however, this crossing is explained by another Kramers' pair where the two splitting bands are very close to each other. The classification of this family of materials as topological insulators remains an open question.

Symmetries of the transfer operator for $Γ_0(N)$ and a character deformation of the Selberg zeta function for $Γ_0(4)$

description: The transfer operator for $Γ_0(N)$ and trivial character $χ_0$ possesses a finite group of symmetries generated by permutation matrices $P$ with $P^2=id$. Every such symmetry leads to a factorization of the Selberg zeta function in terms of Fredholm determinants of a reduced transfer operator. These symmetries are related to the group of automorphisms in $GL(2,\mathbb{Z})$ of the Maass wave forms of $Γ_0(N)$ . For the group $Γ_0(4)$ and Selberg's character $χ_α$ there exists just one non-trivial symmetry operator $P$. The eigenfunctions of the corresponding reduced transfer operator with eigenvalue $λ=\pm 1$ are related to Maass forms even respectively odd under a corresponding automorphism. It then follows from a result of Sarnak and Phillips that the zeros of the Selberg function determined by the eigenvalues $λ=-1$ of the reduced transfer operator stay on the critical line under the deformation of the character. From numerical results we expect that on the other hand all the zeros corresponding to the eigenvalue $λ=+1$ leave this line for $α$ turning away from zero.

Anharmonic resonances with recursive delay feedback

description: We consider application of the multiple time delayed feedback for control of anharmonic (nonlinear) oscillators subject to noise. In contrast to the case of a single delay feedback, the multiple one exhibits resonances between feedback and nonlinear harmonics, leading to a resonantly strong or weak oscillation coherence even for a small anharmonicity. Analytical results are confirmed numerically for van der Pol and van der Pol-Duffing oscillators. Highlights: > We construct general theory of noisy limit-cycle oscillators with linear feedback. > We focus on coherence and "reliability" of oscillators. > For recursive delay feedback control the theory shows importance of anharmonicity. > Anharmonic resonances are studied both numerically and analytically.

description: The quest for gravitational waves from coalescing binaries is customarily performed by the LIGO-Virgo collaboration via matched filtering, which requires a detailed knowledge of the signal. Complete analytical coalescence waveforms are currently available only for the non-precessing binary systems. In this paper we introduce complete phenomenological waveforms for the dominant quadrupolar mode of generically spinning systems. These waveforms are constructed by bridging the gap between the analytically known inspiral phase, described by spin Taylor (T4) approximants in the restricted waveform approximation, and the ring-down phase through a phenomenological intermediate phase, calibrated by comparison with specific, numerically generated waveforms, describing equal mass systems with dimension-less spin magnitudes equal to 0.6. The overlap integral between numerical and phenomenological waveforms ranges between 0.95 and 0.99.
