Capacity constraints on reasoning : developmental aspects
Creators: name: Pachev, Gueorgui Stefanov
Publisher: name: University of British Columbia
Year: 2009

description: The development of children's reasoning has often been associated with the attainment of strategies, higher-order concepts, or a broader knowledge-base. Several researchers have argued that these achievements are parallelled and influenced by a child's capacity to process a fixed amount of information in the context of a reasoning task. It is assumed that children's processing resources increase with age and that this increase allows children to acquire the more complex forms of reasoning, advanced strategies, etc. Insufficient resources, on the other hand, prevent children from performing at a higher level. The present study had two goals: (1) to provide evidence for the increase of resources with age, and (2) to explore the effects asociated with the limited-capacity of the processes involved in reasoning. Two dual-task paradigms were combined in the pursuit of these goals. One paradigm allowed for identifying the level of a task, at which performance was capacity-limited. Age-groups with different amount of resources were expected to exhibit capacity-limited performance at different task-levels. The second approach, based on introducing additional processing load, allowed for comparing the effects of charging the Capacity-limits of different processes involved in reasoning. Eighty-six children from three age-groups were given a matrices-completion task at four levels of difficulty. The task was performed either alone or concurrently with a second task. The secondary task was administered in the beginning or in the middle of some trials, thus disrupting processes at the initial stage and processes at the executive part of the solution. Capacity-limited performance was detected at the third and fourth level of the task for the first two age-groups, respectively. There was an indication that the oldest subjects would exhibit capacity-limited performance at levels beyond the fourth one. Reasoning performance deteriorated when the secondary task disrupted the operation of the executive processes. The additional load introduced in the beginning of a trial, however, did not affect the level of reasoning performance or resulted in improvement in certain conditions. The results were interpreted as supporting the hypothesis that the capacity factor operates as a necessary but not a sufficient condition for the development of reasoning.

description: We introduce the spin Hecke algebra, which is a q-deformation of the spin symmetric group algebra, and its affine generalization. We establish an algebra isomorphism which relates our spin (affine) Hecke algebras to the (affine) Hecke-Clifford algebras of Olshanski and Jones-Nazarov. Relation between the spin (affine) Hecke algebra and a nonstandard presentation of the usual (affine) Hecke algebra is displayed, and the notion of covering (affine) Hecke algebra is introduced to provide a link between these algebras. Various algebraic structures for the spin (affine) Hecke algebra are established.

description: Problem of interpretation. Parliaments and other bodies pour out a steady flow of written laws that affect all our activities. It is thus not surprising to find that the courts are frequently concerned with cases that turn upon the meaning of a particular piece of legislation. In Australia, a rough sample shows that in forty per centum of recent reported cases the courts were required to rule upon the meaning of some legislative instrument. In a further thirty per centum of cases the courts had to apply an Act, regulation, rule, etc., — its meaning this time not being in dispute. 1 It is never easy to express ideas in words and the more complex the idea the greater the difficulty. That which seems to have been clearly explained by the writer may not be so found by the reader. There are many reasons for this. All writing assumes a certain knowledge on the part of the reader, but the writer may have assumed that his reader knew more than was in fact the case and as a result the document may be stated too succinctly or abstrusely. The document may be concerned with something such as a mathematical calculation that does not readily lend itself to a description in words. The idea may be so complex that it requires a very large number of statements, qualifications, exceptions and so on to set it out. Or the writer may not have foreseen all the subtle variations of human conduct relating to the topic dealt with in the document and thereby not have provided for some particular activity. These are but some of the difficulties that confront both writer and reader of any document and they are all magnified in regard to legislation.

description: In this paper we introduce a method for stacking data cubelets extracted from interferometric surveys of galaxies in the redshifted 21-cm H\,\textsc{i} line. Unlike the traditional spectral stacking technique, which stacks one-dimensional spectra extracted from data cubes, we examine a method based on image domain stacks which makes deconvolution possible. To test the validity of this assumption, we mock a sample of 3622 equatorial galaxies extracted from the GAMA survey, recently imaged as part of a DINGO-VLA project. We first examine the accuracy of the method using a noise-free simulation and note that the stacked image and flux estimation are dramatically improved compared to traditional stacking. The extracted H\,\textsc{i} mass from the deconvolved image agrees with the average input mass to within 3\%. However, with traditional spectral stacking, the derived H\,\textsc{i} is incorrect by greater than a factor of 2. For a more realistic case of a stack with finite S/N, we also produced 20 different noise realisations to closely mimic the properties of the DINGO-VLA interferometric survey. We recovered the predicted average H\,\textsc{i} mass to within $\sim$4\%. Compared with traditional spectral stacking, this technique extends the range of science applications where stacking can be used, and is especially useful for characterizing the emission from extended sources with interferometers.

Bacterial disinfection by the photo-Fenton process: extracellular oxidation or intracellular photo-catalysis?

description: Pre-proof versionIn this work, we evidence that despite the addition of the Fenton reagents in the bulk, the photo-Fenton mediated inactivation is mainly an intracellular process. We compare the inactivation kinetics of a typical E. coli strain that can exchange solutes with its environment through its outer membrane porins with its porinless mutant counterpart. The transport of Fe2+ and H2O2 into the bacterial cell was hypothesized to be the limiting factor of the photo-Fenton-mediated inactivation. This important pathway that could initiate intracellular oxidative chain reactions would be evidenced by the use of a porinless bacterial strain, derivative of MC4100 (TK821). The comparison among the typical E. coli K12 (ATCC 23716) and TK821 showed that the processes that constitute the photo-Fenton (solar, solar/Fe2+, solar/H2O2) are greatly modified between the two strains. ATCC 23716 was always inactivated faster than the TK821, and a 45% and 150% difference in inactivation rate was measured for the solar/Fe2+ and the solar/H2O2 processes. The photo-Fenton process inactivation rates were doubled, and the contribution of the intracellular and extracellular pathways was estimated. The mechanisms taking place in the bulk were twice as important for TK821, while the inverse was estimated for the intracellular events in ATCC 23716. The results of this work demonstrate that porins are essentially a regulator of the photo-Fenton disinfection, and that is mainly an intracellular advanced oxidation process.

Schymanski Luxembourg Centre for Systems Biomedicine (LCSB), University of Luxembourg, 6 avenue du Swing, 4367 Belvaux, Luxembourg. ORCID: 0000-0001-6868-8145. Abstract: The environment and the chemicals to which we are exposed is incredibly complex, with over 111 million chemicals in the largest open chemical databases, 300,000 estimated in global inventories of high use, and over 70,000 in household use alone. Detectable molecules in environmental samples, metabolomics and exposomics can now be captured using high resolution mass spectrometry (HRMS), which provides a “snapshot” of all chemicals present in a sample and allows for retrospective data analysis through digital archiving. However, there is no “one size fits all” analytical method, and scientists cannot yet identify most of the tens of thousands of features in each sample, let alone associate them with health or disease, leading to critical bottlenecks in identification and data interpretation. Defining the chemical space to search is a huge challenge, especially considering that chemicals transform in both organisms (metabolism) and the environment (both biotic and abiotic processes). This talk will cover European and worldwide community initiatives and resources to help find and identify small molecules and their metabolites (transformation products) - from compound databases to spectral libraries, from literature mining to transformation prediction. It will show how FAIR and Open interdisciplinary efforts and data sharing can facilitate research in many areas of small molecule research. Various contributors to this massive collaborative effort will be acknowledged throughout the talk.

description: The burgeoning integration of distributed energy resources (DER) poses new challenges for the economic and safe operation of the electricity system. The current distribution-side policy is largely based on mandatory regulations and incentives, rather than the design of a competitive market mechanism to arouse DERs to freely compete in the retail market. To address this issue, we proposed a transactive retail market mechanism to attract the active participation of profit-driven DER retailers in a deregulated way. Considering the limited competitive property of the retail market, a bi-level DSO-dominated framework is constructed to simulate the virtual game between distribution system operator (DSO) and DER retailers. Specifically, the flexible interval pricing of retailers is modeled as a series of binary revenue constraints to influence the DSO's centralized economic dispatch decisions, where the time-varying distribution locational marginal price is adopted to settle energy activities at different locations over the time horizon. Due to the uncertain power flow path during the coordinated decision-making process, we proposed a general undirected second-order cone-based AC radial power flow model and provided sufficient conditions to ensure its exactness. Also, we applied a series of approximation and relaxation techniques to transform the bi-level mixed-integer quadratic framework with highly discrete induced domains into a solvable mixed-integer semidefinite programming problem. It is demonstrated in the case study that the proposed mechanism can not only improve market efficiency but also eliminate market power and the resulting market failures.

description: We investigate the quantum Mpemba effect from the perspective of non-equilibrium quantum thermodynamics by studying relaxation dynamics of quantum systems coupled to a Markovian heat bath, which are described by Davies maps. Starting from a state with coherences in the energy eigenbasis, we demonstrate that an exponential speedup to equilibrium will always occur if the state is transformed to a diagonal state in the energy eigenbasis, provided that the spectral gap of the generator is defined by a complex eigenvalue. When the transformed state has a higher nonequilibrium free energy, we argue using thermodynamic reasoning that this is a \textit{genuine} quantum Mpemba effect. Furthermore, we show how a unitary transformation on an initial state can always be constructed to yield the effect and demonstrate our findings by studying the dynamics of both the non-equilibrium free energy and the irreversible entropy production in single and multi-qubit examples.

description: The usual concepts of topological physics, such as the Berry curvature, cannot be applied directly to non-Hermitian systems. We show that another object, the quantum metric, which often plays a secondary role in Hermitian systems, becomes a crucial quantity near exceptional points in non-Hermitian systems, where it diverges in a way that fully controls the description of wavepacket trajectories. The quantum metric behaviour is responsible for a constant acceleration with a fixed direction, and for a non-vanishing constant velocity with a controllable direction. Both contributions are independent of the wavepacket size.

description: We use first-principles simulation and virtual crystal approximation to reveal the unique double band inversion and topological phase transition in Ge1-xSnx alloys. Wavefunction parity, spatial charge distribution and surface state spectrum analyses suggest that the band inversion in Ge1-xSnx is relayed by its first valence band. As the system evolves from Ge to α-Sn, its conduction band moves down, and inverts with the first and the second valence bands consecutively. The first band inversion makes the system nontrivial, while the second one does not change the topological invariant of the system. Both the band inversions yield surface modes spanning the individual inverted gaps, but only the surface mode in the upper gap associates with the nontrivial nature of tensile-strained α-Sn.

description: This study evaluates the performance of ChatGPT variants, GPT-3.5 and GPT-4, both with and without prompt engineering, against solely student work and a mixed category containing both student and GPT-4 contributions in university-level physics coding assignments using the Python language. Comparing 50 student submissions to 50 AI-generated submissions across different categories, and marked blindly by three independent markers, we amassed $n = 300$ data points. Students averaged 91.9% (SE:0.4), surpassing the highest performing AI submission category, GPT-4 with prompt engineering, which scored 81.1% (SE:0.8) - a statistically significant difference (p = $2.482 \times 10^{-10}$). Prompt engineering significantly improved scores for both GPT-4 (p = $1.661 \times 10^{-4}$) and GPT-3.5 (p = $4.967 \times 10^{-9}$). Additionally, the blinded markers were tasked with guessing the authorship of the submissions on a four-point Likert scale from `Definitely AI' to `Definitely Human'. They accurately identified the authorship, with 92.1% of the work categorized as 'Definitely Human' being human-authored. Simplifying this to a binary `AI' or `Human' categorization resulted in an average accuracy rate of 85.3%. These findings suggest that while AI-generated work closely approaches the quality of university students' work, it often remains detectable by human evaluators.

description: Human pose transfer, which aims at transferring the appearance of a given person to a target pose, is very challenging and important in many applications. Previous work ignores the guidance of pose features or only uses local attention mechanism, leading to implausible and blurry results. We propose a new human pose transfer method using a generative adversarial network (GAN) with simplified cascaded blocks. In each block, we propose a pose-guided non-local attention (PoNA) mechanism with a long-range dependency scheme to select more important regions of image features to transfer. We also design pre-posed image-guided pose feature update and post-posed pose-guided image feature update to better utilize the pose and image features. Our network is simple, stable, and easy to train. Quantitative and qualitative results on Market-1501 and DeepFashion datasets show the efficacy and efficiency of our model. Compared with state-of-the-art methods, our model generates sharper and more realistic images with rich details, while having fewer parameters and faster speed. Furthermore, our generated images can help to alleviate data insufficiency for person re-identification.

description: We prove a new kind of quantum de Finetti theorem for representations of the unitary group U(d). Consider a pure state that lies in the irreducible representation U_{mu+nu} for Young diagrams mu and nu. U_{mu+nu} is contained in the tensor product of U_mu and U_nu; let xi be the state obtained by tracing out U_nu. We show that xi is close to a convex combination of states Uv, where U is in U(d) and v is the highest weight vector in U_mu. When U_{mu+nu} is the symmetric representation, this yields the conventional quantum de Finetti theorem for symmetric states, and our method of proof gives near-optimal bounds for the approximation of xi by a convex combination of product states. For the class of symmetric Werner states, we give a second de Finetti-style theorem (our 'half' theorem); the de Finetti-approximation in this case takes a particularly simple form, involving only product states with a fixed spectrum. Our proof uses purely group theoretic methods, and makes a link with the shifted Schur functions. It also provides some useful examples, and gives some insight into the structure of the set of convex combinations of product states.

description: The thesis examines the effects of rural-urban migration on migrants' marriage, fertility and smoking behaviour. This research attempts to fill these gaps. The data used are from the Chinese Rural Household sample of Rural-Urban Migration in China and Indonesia (RUMiCI) project. Chapter 2 analyses the effect of rural-urban migration on fertility behaviour of rural females in China. The results show that the rural-urban migration decreases the number of births and delays the timing of the first birth. On average, the first birth is delayed about seven months. Furthermore, it is suggested that female migrants postpone their marriages, and subsequently the timing of the first birth. Chapter 3 examines the correlation between the timing of the first marriage and the first rural-urban migration. It is found that male migrants marry four months earlier and female migrants four months later than their rural counterparts. In details, the accelerating effect of migration for males significantly depends on the duration of migration; for females, the postponement effect of migration varies across birth cohorts. Chapters 4 and 5 explore the effect of rural-urban migration on cigarette smoking from two perspectives - smoking prevalence and age of smoking onset. The results show that the rural-urban migration has a significant and positive effect on current smoking prevalence. In terms of the timing of smoking onset, rural-urban migration can increase the hazard rate of smoking substantially, and counterfactual experiments show that the lifetime prevalence of smoking can also be increased significantly. More alarmingly, the effect of migration is extremely substantial for younger birth cohorts.

For certain values of the parameters the new model becomes quadratic. We calculate in closed form the entropy and impurity occupation as functions of temperature and identify the different physical energy scales of the problem. We show how, as the temperature goes to zero, the model approaches a universal line of fixed points non-Fermi liquid in nature.

Making use of the full self-energy that takes into account all ladder-, and rainbow-type diagrams, we are able to calculate the relevant low temperature quantities for arbitrary impurity concentration and scattering rates. These are the density of states, specific heat and the shift in the chemical potential. Our results therefore cover the whole parameter space: they include both the self-consistent Born and the resonant unitary limits, and most importantly give exact results in between.

description: In the context of stochastic thermodynamics, a minimal model for non equilibrium steady states has been recently proposed: the Brownian Gyrator (BG). It describes the stochastic overdamped motion of a particle in a two dimensional harmonic potential, as in the classic Ornstein-Uhlenbeck process, but considering the simultaneous presence of two independent thermal baths. When the two baths have different temperatures, the steady BG exhibits a rotating current, a clear signature of non equilibrium dynamics. Here, we consider a time-dependent potential, and we apply a reverse-engineering approach to derive exactly the required protocol to switch from an initial steady state to a final steady state in a finite time $τ$. The protocol can be built by first choosing an arbitrary quasi-static counterpart - with few constraints - and then adding a finite-time contribution which only depends upon the chosen quasi-static form and which is of order $1/τ$. We also get a condition for transformations which - in finite time - conserve internal energy, useful for applications such as the design of microscopic thermal engines. Our study extends finite-time stochastic thermodynamics to transformations connecting non-equilibrium steady states.

description: Network Functions Virtualization (NFV) allows flexibility, scalability, agility, and easy manageability of networks by leveraging the features of virtualization and cloud computing technologies. However, softwarization of network functions imposes many challenges. Reliability and latency are major challenges in NFV-enabled 5G networks that can lead to customer dissatisfaction and revenue loss. In general, redundancy is used to improve the reliability of communication services. However, redundancy requires the same amount of additional resources and thus increases cost. In this work, we address the reliability-aware, delay guaranteed, and resource efficient Service Function Chain (SFC) placement problem in softwarized 5G networks. First, we propose a novel SFC subchaining method to enhance the reliability of an SFC without backups. If reliability requirement is not met after subchaining method, we add backups to VNFs to meet the reliability requirement. Then, we formulate the reliable SFC placement problem as an Integer Linear Programming (ILP) problem in order to solve it optimally. Owing to high computational complexity of the ILP problem for solving large input instances, we propose a modified stable matching algorithm to provide near-optimal solution in polynomial time. By extensive simulations we show that our proposed solutions consume lesser physical resources compared to state-of-the-art solutions for provisioning reliable communication services.

description: In this study we explore the astrophysical implications of pressure anisotropy on the physical characteristics of millisecond pulsars within the framework of $f(Q)$ gravity, {in particular $f(Q)=-α\, Q - β$, where $α$ and $β$ are constants.} Starting off with the field equations for anisotropic matter configurations, we adopt the physically salient Durgapal-Fuloria ansatz together with a well-motivated anisotropic factor for the interior matter distribution. This leads to a nonlinear second order differential equation which is integrated to give the complete gravitational and thermodynamical properties of the stellar object. The resulting model is subjected to rigorous tests to ensure that it qualifies as a physically viable compact object within the $f(Q)$-gravity framework. We study in detail the impact of anisotropy on the mass, radius and stability of the star. Our analyses indicate that our models are well-behaved, singularity-free and can account for the existence of a wide range of observed pulsars with masses ranging from 2.08 to 2.67 $M_{\odot}$, with the upper value being in the so-called {\em mass gap} regime observed in gravitational events such as GW190814. {A comparison of the so-called {\em Symmetric Teleparallel Equivalent to GR} (STEGR) models with classical General Relativity (GR) models reveal that the anisotropy parameter and the sign of $β$ impact on the predicted radii of pulsars. In particular, STEGR models have larger radii than their GR counterparts.

Lifshitz scaling effects on the holographic p-wave superconductors coupled to nonlinear electrodynamics

description: We employ gauge/gravity duality to study the effects of Lifshitz scaling on the holographic $p$ wave superconductors in the presence of Born-Infeld (BI) nonlinear electrodynamics. By using the shooting method in the probe limit, we calculate the relation between critical temperature $T_{c}$ and $ρ^{z/d}$ numerically for different values of mass, nonlinear parameter $b$ and Lifshitz critical exponent $z$ in various dimensions. We observe that critical temperature decreases by increasing $b$, $z$ or the mass parameter $m$ which makes conductor/superconductor phase transition harder to form. In addition, we analyze the electrical conductivity and find the behavior of real and imaginary parts as a function of frequency which depend on the model parameters. However, some universal behaviors are seen. For instance at low frequencies, real part of conductivity shows a delta function behavior while the imaginary part has a pole which means that these two parts are connected to each other through Kramers-Kronig relation. The behavior of real part of conductivity in the large frequency regime can be achieved by $Re[σ]=ω^{D-4}$. Furthermore, with increasing the Lifshitz scaling $z$, the energy gap and the minimum values of the real and imaginary parts become unclear.

Modelling the spectral energy distribution of galaxies. IV Correcting apparent disk scalelengths and central surface brightnesses for the effect of dust at optical and near-infrared wavelengths

description: We present corrections for the change in the apparent scalelengths, central surface brightnesses and axis ratios due to the presence of dust in pure disk galaxies, as a function of inclination, central face-on opacity in the B-band (tau^f_B) and wavelength. The correction factors were derived from simulated images of disk galaxies created using geometries for stars and dust which can reproduce the entire spectral energy distribution from the ultraviolet (UV) to the Far-infrared (FIR)/submillimeter (submm) and can also account for the observed surface-brightness distributions in both the optical/Near-infrared and FIR/submm. We found that dust can significantly affect both the scalelength and central surface brightness, inducing variations in the apparent to intrinsic quantities of up to 50 percent in scalelength and up to 1.5 magnitudes in central surface brightness. We also identified some astrophysical effects for which, although the absolute effect of dust is non-negligible, the predicted variation over a likely range in opacity is relatively small, such that an exact knowledge of opacity is not needed. Thus, for a galaxy at a typical inclination of 37 degrees and having any tau^f_B>2, the effect of dust is to increase the scalelength in B relative to that in I by a factor of 1.12 +- 0.02 and to change the B-I central colour by 0.36 +- 0.05 magnitudes. Finally we use the model to analyse the observed scalelength ratios between B and I for a sample of disk-dominated spiral galaxies, finding that the tendency for apparent scalelength to increase with decreasing wavelength is primarily due to the effects of dust.

Structural studies of the ETS domain

Publisher: name: University of British Columbia
Year: 2009

description: This thesis describes the cloning, overexpression, biophysical and structural analyses of fragments from murine Ets-1 that comprise the ETS domain, a motif responsible for the sequence-specific DNA binding activity of the ets family. Multidimensional nuclear magnetic resonance (NMR) techniques feature prominently throughout this study. From the tertiary structure of a 110 residue Ets-1 fragment, the ETS domain is demonstrated to possess a winged helix-turn-helix fold. As the name suggests, the winged helix-turnhelix motif is comprised of a helix-turn-helix motif and a characteristic (3-sheet component which pack to form a compact domain. In some members of the winged helix-turn-helix family, a mobile wing-like (3-turn supplies base-specific contacts to augment contacts made by the recognition helix. The ETS domain of Ets-1 is flanked by amino- and carboxy-terminal sequences that cooperate to attenuate DNA binding affinity by approximately twenty fold. Through structural analysis of a larger, 142 residue fragment of Ets-1, the flanking inhibitory sequences are shown to form a module comprised of two N-terminally located cc-helices, one C-terminally located ct-helix and one cc-helix from the ETS domain. An allosteric mechanism of repression is proposed as the inhibition module is located on different face of the ETS domain relative to the recognition helix. Dynamic information obtained from ¹⁵N relaxation and fast amide hydrogen exchange experiments support this mechanism of Ets-1 intramolecular inhibition.

description: In this study, we investigate the behavior of inertial active Brownian particles in a $d$-dimensional harmonic trap in the presence of translational diffusion. While the solution of the Fokker-Planck equation is generally challenging, it can be utilized to compute the exact time evolution of all time-dependent dynamical moments using a Laplace transform approach. We present the explicit form for several moments of position and velocity in $d$-dimensions. An interplay of time scales assures that the effective diffusivity and steady-state kinetic temperature depend on both inertia and trap strength, unlike passive systems. We present detailed `phase diagrams' using kurtosis of velocity and position showing possibilities of re-entrance.
