The Rod Young affair in the B.C. Co-operative Commonwealth Federation
Creators: name: Bernard, Elaine
Publisher: name: University of British Columbia
Year: 2010

description: The years 1949 to 1956 saw a period of constant warfare between two factions within the British Columbia Co-operative Commonwealth Federation. These groups represented basically the right and left in the party. The left wing challenged what they considered to be a continuing rightward drift of the party. Fearing that the party was on the road to becoming "Liberals-in-a-hurry" the left attempted to organize an opposition to this rightward drift, and to rally support for socialist policies within the party. As early as 1949, the right wing was trying to blame the left for the party's failure in the provincial election of that year. The right argued that the left kept the party divided organizationally and that it frightened off supporters and potential supporters with its rhetoric. In the factional battles the name of Rod Young figured prominently as a widely recognized leader of the left wing. During his twenty-one year party membership, Young held such important elected positions as national Vice-President of the Co-operative Commonwealth Youth Movement, Second Vice-President of the BC party, and CCF member of Parliament from Vancouver Centre. He was disciplined by the party on three separate occasions, each one arising out of a major ideological dispute: in 1937 the united front question, in 1950 the organizing of the Socialist Fellowship and in 1954 the debate on relations between Communists and the CCF. It was the last of these episodes which led to Young's resignation from the CCF. The disciplining of Rod Young in 1954 and his subsequent resignation from the party was a key victory for the right wing. Young came under attack for his left wing views and his criticism of trends within the party. The motive for the attack was clearly ideological differences, but injudicious actions by Rod Young enabled the right wing to characterize a principled opposition as "personal idiosyncracy" and "an organizational question." By thus avoiding direct ideological confrontation the right wing was able to defuse membership opposition to action against the left. Rod Young became the stick with which the right successfully beat the left.
Dependence of vortex phase transitions in mesoscopic BSCCO superconductor at tilted magnetic fields

description: A micron sized single crystal of the superconductor BSCCO was studied using silicon mechanical micro-oscillators at various tilt angles of the dc magnetic field with respect to the c axis of the sample. Different phases of the vortex matter were detected by measuring changes in the value and sign of the oscillator resonant frequency variation with temperature. We could explain the change in the sign of this variation at high temperatures as the transition from the 2D liquid of decoupled pancakes to a reversible 3D vortex lattice. The data indicates that this transition only depends on the magnetic field perpendicular to the superconducting layers while the dissipation involved in this process depends on the component parallel to them.

Modality as a Creative Source in the Second Movement of Nikos Skalkottas's Concerto for Two Violins (Variations on the Rebetiko Song "Tha pao ekei stin Arapia")

description: Nikos Skalkottas's oeuvre includes tonal, atonal, twelve-tone and serial compositions. Also, his musical language frequently includes Greek folk elements, such as folk or folk-like tunes, traditional rhythms and modes. In his Concerto for two violins and orchestra, composed in Athens in 1944-45 and never performed during his lifetime, he chose the rebetiko song by Vassilis Tsitsanis "Tha pao ekei stin Arapia «as a theme for the Variations form of the second movement. The theme is formed by an almost exact version of the song's melody harmonized by the composer. The overall atonal context of the movement is created by the multiple layers of musical texture, in which modal interchange, modulation, added chromatic elements and consecutive or simultaneous use of different modes have as a result extreme chromaticism. The present paper tries to explore the way that modal elements, which either exist in the rebetiko tune or arise in Skalkottas's variations, are used in order to serve as a source for the transformations of the thematic melodic material (especially in the third variation). The starting point of the analysis will be the re-harmonization of the modal melody. Then, the analytical procedure will focus on the way modal pitch relations as well as intervallic relations (horizontal or vertical) establish (or not) pitch centers and symmetries as part of the pitch organization of the movement. Also, the issues of transposition, polymodal chromaticism, developing variation and other features and compositional techniques relating to the overall realization of the variation process will be examined and presented.

description: The inscription F. Delph. III, I, no 547 was discovered in Delphi a few meters east of the thesaurus of Sikyonion. The editor of the inscription, Emile Bourguet, determined the age of the inscription in the Late Antiquity period (138-161 AD). The inscription is interesting in connection with the study of nomenclature and historical origins of the pythkiauli, the folk wind instrument of Cyprus. Through ethnomusicological approach, we found information which illuminate unknown aspects of the topic. Following a close study of all the available etymologies in academia, we cross-checked the elements drawn from factual material of the research with the elements from historical sources and as a result, we reached the most convincing and most correct interpretation of the instrument’s nomenclature.

description: Normalizing flows are an essential alternative to GANs for generative modelling, which can be optimized directly on the maximum likelihood of the dataset. They also allow computation of the exact latent vector corresponding to an image since they are composed of invertible transformations. However, the requirement of invertibility of the transformation prevents standard and expressive neural network models such as CNNs from being directly used. Emergent convolutions were proposed to construct an invertible 3$\times$3 CNN layer using a pair of masked CNN layers, making them inefficient. We study conditions such that 3$\times$3 CNNs are invertible, allowing them to construct expressive normalizing flows. We derive necessary and sufficient conditions on a padded CNN for it to be invertible. Our conditions for invertibility are simple, can easily be maintained during the training process. Since we require only a single CNN layer for every effective invertible CNN layer, our approach is more efficient than emerging convolutions. We also proposed a coupling method, Quad-coupling. We benchmark our approach and show similar performance results to emergent convolutions while improving the model's efficiency.

Addressing the Modality of Church Melodies, According to the Variety in the Choice of the Isokratema. Case Studies
Creators: name: Kanakis, Symeon
Publisher: name: Series Musicologica Balcanica
Year: 2021
Subjects: Isokratema, bordun tone, ethos, analysis and meta-aesthetics of Byzantine chant

description: This paper aims to investigate the phenomenon of heterophony in Byzantine chant, exploring the technique of isokratema and how the modality of a melody can be affected by the selection of an isokratematic note (bordun tone). Specific examples of whole melodies or melodic phrases are examined by using respectively two or more versions of isokratema. These versions come either from recordings of isokratema in church melodies or voice recordings from in and out of the worship congregation and the oral tradition. Additionally, the selections of isokratema are analysed one by one in order to show how each example affects the modality of the melos as an octaechic behaviour on macrostructural level, as well as a movement of the notes on microstructural level. Finally, we examine the role of the modality of each example in the determination of the melody’s ethos, within the broader context of the meta-aesthetics of Byzantine chant.

Modal References in the Byzantine Heirmologion. The Medial Signatures in the Manuscript Grottaferrata E.γ.III
Creators: name: Martani, Sandra
Publisher: name: Series Musicologica Balcanica
Year: 2021
Subjects: Heirmologion, Palaeobyzantine notation, Coislin notation, medial signature, phthora, nana, nenano

description: In the Byzantine notations, the main purpose of the medial signatures (MeSi) is to clarify aspects of modal changes in the melody, wich are usually connected with the structure of the text. In the Palaeobyzantine heirmologia the use of MeSi is limited, since the plain modal structure and the short texts do not offer the opportunity to build articulate modulations. In this respect the MS Grottaferrata E.γ.III reveals peculiar characteristics, because it contains a greater number of MeSi than the other heirmologia. The analysis of the MeSi and the phthorai used in this codex shows that they both seem to be not only a signal for brief modulations or transpositions, but also a “diastematic” indication. In any case, based on present knowledge, some occurrences remain without a plausible explanation.

description: Context. Cosmic rays (CRs) play an important role in the chemistry and dynamics of the interstellar medium. In dense environments, they represent the main ionising agent, driving the rich chemistry of molecular ions and determining the ionisation fraction, which regulates the degree of coupling between the gas and magnetic fields. Estimates of the CR ionisation rate ($ζ_2$) span several orders of magnitude, depending on the targeted sources and on the used method. Aims. Recent theoretical models have characterised the CR attenuation with increasing density. We aim to test these models for the attenuation of CRs in the low-mass pre-stellar core L1544. Methods. We use a state-of-the-art gas-grain chemical model, which accepts the CR ionisation rate profile as input, to predict the abundance profiles of four ions: $\rm N_2H^+$, $\rm N_2D^+$, $\rm HC^{18}O^+$, and $\rm DCO^+$. Non-LTE radiative transfer is performed to produce synthetic spectra based on the derived abundances. These are compared with observations obtained with the Institut de Radioastronomie Millimétrique (IRAM) 30m telescope. Results. Our results indicate that a model with $ζ_2 > 10^{-16} \rm \, s^{-1}$ is excluded by the observations. Also the model with the standard $ζ_2 = 1.3 \times 10^{-17} \rm \, s^{-1}$ produces a worse agreement with respect to the attenuation model based on Voyager observations, which has an average $ζ_2 = 3 \times 10^{-17} \rm \, s^{-1}$ at the column densities typical of L1544. The single-dish data, however, are not sensitive to the attenuation of the CR profile, which changes only by a factor of two in the range of column densities spanned by the core model. Interferometric observations at higher spatial resolution, combined with observations of transitions with lower critical density are needed to observe a decrease of $ζ_2$ with density.

description: We study the current structure of the lepton flavor violating $τ\to3μ$ decay in Type-III 2HDM. This model has many coupling constants which affect this decay. We find that each coupling constant corresponds to the different final-state momenta distribution and vice versa. Using this fact, we suggest how to determine the current structure. We also find the upper limit $|η_{23}^Eη_{22}^E|<0.00022$ in the case that all Higgs bosons except for the lighter CP even neutral one $h^0$ are decoupled, $M_{h^0}=115$GeV and $\cosβ=1/\sqrt{2}$. The observable difference between the MSSM and type-III 2HDM is also discussed.

description: In the spring of 1928, Miron – the first Patriarch of the Romanian Orthodox Church – established The Academy of Religious Music in Bucharest, the only academic music institution in Romania, at the time, whose purpose was – from the perspective of its founder, the Patriarch – the rehabilitation of the status of Byzantine music in the Orthodox Church and the establishment of a coherent relationship with Western vocal religious music. The present article investigates the historical, social and cultural context of the establishment of this singular institution of religious music education in Romania, as well as its necessity, objectives and utility. It also explores the benefits it brought to Romanian Orthodox religious music and to the Church, until 1948, when it was disbanded by the Communist regime.

description: The rapid rotation of Be stars may be caused in some cases by past mass and angular momentum accretion in an interacting binary in which the mass donor is currently viewed as a small, hot subdwarf stripped of its outer envelope. Here we report on the spectroscopic detection of such a subdwarf in the Be binary system FY Canis Majoris from the analysis of data acquired by the IUE spacecraft and KPNO Coude Feed Telescope over the course of 16 and 21 years, respectively. We present a double-lined spectroscopic orbit for the binary based upon radial velocities from the IUE spectra and use the orbital solutions with a Doppler tomography algorithm to reconstruct the components' UV spectra. The subdwarf is hot (T_eff = 45+/-5 kK) and has a mass of about 1.3 M_sun and a radius of about 0.6 R_sun. It contributes about 4% as much flux as the Be star does in the FUV. We also present observations of the H-alpha and He I 6678 emission features that are formed in the circumstellar disk of the Be star. Orbital flux and velocity variations in the He I 6678 profile indicate that much of the emission forms along the disk rim facing the hot subdwarf where the disk is probably heated by the incident radiation from the subdwarf. A study of the FUV infall shell lines discovered in the 1980s confirms their episodic presence but reveals that they tend to be found around both quadrature phases, unlike the pattern in Algol binaries. Phase-dependent variations in the UV N V doublet suggest the presence of a N-enhanced wind from the subdwarf and a possible shock-interaction region between the stars where the subdwarf's wind collides with the disk of the Be star.

description: This research explores the musical culture of an unknown area of Northwestern Greece (Western Macedonia and Epirus) and its neighboring areas in the State of North Macedonia and Northern Epirus in Southern Albania. It reveals that areas considered alien and linguistically distinguished from each other, belong to the same musical culture despite the difference of language. Thus the conventional division of the area of Western Macedonia in Greece into three zones, the Greek-speaking part (the largest one), the Vlach-speaking part (on the Pindus Mountains), and the Slav-speaking, on the Northern part of the area, is seriously disputed. Emic comments of the locals about their language and identity, justify these findings and are confirmed by historical research in the Byzantine past of the area.

description: We study how coarse-graining procedure of an underlying UV-complete quantum gravity gives rise to a connected geometry. It has been shown, quantum entanglement plays a key role in the emergence of such a geometric structure, namely a smooth Einstein-Rosen bridge. In this paper, we explore the possibility of the emergence of similar geometric structure from classical correlation, in the AdS/CFT setup. To this end, we consider a setup where we have two decoupled CFT Hilbert spaces, then choose a random typical state in one of the Hilbert spaces and the same state in the other. The total state in the fine-grained picture is of course a tensor product state, but averaging over the states sharing the same random coefficients creates a geometric connection for simple probes. Then, the apparent spatial wormhole causes a factorization puzzle. We argue that there is a spatial analog of half-wormholes, which resolves the puzzle in the similar way as the spacetime half-wormholes.

description: We present the first results of AKARI Infrared Camera near-infrared spec- troscopic survey of the Large Magellanic Cloud (LMC). We detected absorption features of the H2O ice 3.05 um and the CO2 ice 4.27 um stretching mode toward seven massive young stellar objects (YSOs). These samples are for the first time spectroscopically confirmed to be YSOs. We used a curve-of-growth method to evaluate the column densities of the ices and derived the CO2/H2O ratio to be 0.45 pm 0.17. This is clearly higher than that seen in Galactic massive YSOs (0.17 pm 0.03). We suggest that the strong ultraviolet radiation field and/or the high dust temperature in the LMC may be responsible for the observed high CO2 ice abundance.

description: Four-boson Efimov physics is well known in the negative energy regime but far less above the four-body breakup threshold. The part of this region with negative two-boson scattering length is studied solving rigorous four-particle scattering equations for transition operators in the momentum space. Moving away from the unitary limit the Efimov tetramers evolve from unstable bound states into resonances. Their energies and widths are studied as functions of the two-boson scattering length; a universal behavior is established and given in a dimensionless representation. The Efimov tetramers have finite width in the whole regime; they broaden rapidly in the resonance regime but remain narrower than the associated trimer. The resonant behavior is most clearly seen in the four-particle recombination rate.

description: We study the kinematics of timelike geodesic congruences in two and four dimensions in spacetime geometries representing stringy black holes. The Raychaudhuri equations for the kinematical quantities (namely, expansion, shear and rotation) characterising such geodesic flows are written down and subsequently solved analytically (in two dimensions) and numerically (in four dimensions) for specific geodesics flows. We compare between geodesic flows in dual (electric and magnetic) stringy black hole backgrounds in four dimensions, by showing the differences that arise in the corresponding evolutions of the kinematic variables. The crucial role of initial conditions and the spacetime curvature on the evolution of the kinematical variables is illustrated. Some novel general conclusions on geodesic focusing are obtained from the analytical and numerical findings. We also propose new quantifiers in terms of (a) the time (affine parameter) of approach to a singularity and (b) the location of extrema in the functional evolution of the kinematic variables, which may be used to distinguish between flows in different geometries. In summary, our quantitative findings bring out hitherto unknown features of the kinematics of geodesic flows, which, otherwise, would have remained overlooked, if we confined ourselves to only a qualitative analysis.

description: We describe a low-cost and simple setup for hyperthermia measurements on colloidal solutions of magnetic nanoparticles (ferrofluids) with a frequency-adjustable magnetic field in the range 5-500 kHz produced by an electromagnet. By optimizing the general conception and each component (nature of the wires, design of the electromagnet), a highly efficient setup is obtained. For instance, in a useful gap of 1.1 cm, a magnetic field of 4.8 mT is generated at 100 kHz and 500 kHz with an output power of 3.4 W and 75 W, respectively. A maximum magnetic field of 30 mT is obtained at 100 kHz. The temperature of the colloidal solution is measured using optical fiber sensors. To remove contributions due to heating of the electromagnet, a differential measurement is used. In this configuration the sensitivity is better than 1.5 mW at 100 kHz and 19.3 mT. This setup allows one to measure weak heating powers on highly diluted colloidal solutions. The hyperthermia characteristics of a solution of Fe nanoparticles are described, where both the magnetic field and the frequency dependence of heating power have been measured.

description: The Tracking Ultraviolet Set-up (TUS) is the world's first orbital imaging detector of Ultra High Energy Cosmic Rays (UHECR) and it operated in 2016-2017 as part of the scientific equipment of the Lomonosov satellite. The TUS was developed and manufactured as a prototype of the larger project K-EUSO with the main purpose of testing the efficiency of the method for measuring the ultraviolet signal of extensive air shower (EAS) in the Earth's night atmosphere. Despite the low spatial resolution ($\sim5\times5$ km$^2$ at sea level), several events were recorded which are very similar to EAS as for the signal profile and kinematics. Reconstruction of the parameters of such events is complicated by a short track length, an asymmetry of the image, and an uncertainty in the sensitivity distribution of the TUS channels. An advanced method was developed for the determination of event kinematic parameters including its arrival direction. In the present article, this method is applied for the analysis of 6 EAS-like events recorded by the TUS detector. All events have an out of space arrival direction with zenith angles less than 40°. Remarkably they were found to be over the land rather close to United States airports, which indicates a possible anthropogenic nature of the phenomenon. Detailed analysis revealed a correlation of the reconstructed tracks with direction to airport runways and Very High Frequency (VHF) omnidirectional range stations. The method developed here for reliable reconstruction of kinematic parameters of the track-like events, registered in low spatial resolution, will be useful in future space missions, such as K-EUSO.

Interviews
Advances in technology and the increase of devices that can generate or operate on DC power are again raising the debate over AC vs. DC power. Eliminating conversions from DC to AC and vice versa can greatly improve the efficiency of both the grid and the devices that can operate in a DC mode. Solar photovoltaic panels, batteries and fuel cells generate/store DC power, and residential, commercial, and industrial facilities are projected to increase DC electrical loads that do not require first converting to AC. In developed regions of the world where the AC power grid is well established, it may not be feasible to change over large portions of the existing grid to DC. However, certain aspects of the grid, such as distribution primaries and secondaries may be candidates for a DC revolution. World regions where electric infrastructure is developing may have a greater opportunity to take advantage of the economic benefits of being able to adopt the latest innovations in DC energy production, transportation, and end-use technologies. With this in mind, several IEEE Smart Grid experts were asked to provide their input to the question: What do you see as the future of AC and DC power, relating to various world regions.

description: Synthetic microswimmers offer models for cell motility and their tunability makes them promising candidates for biomedical applications. Here we measure the acoustic propulsion of bimetallic micro-rods that, when trapped at the nodal plane of a MHz acoustic resonator, swim with speeds of up to 300 microns per second. While past acoustic streaming models predict speeds that are more than one order of magnitude smaller than our measurements, we demonstrate that the acoustic locomotion of the rods is driven by a viscous, non-reciprocal mechanism relying on shape anisotropy akin to that used by swimming cells and that reproduces our data with no adjustable parameters.

description: The spectrum of low-lying eigenvalues of overlap Dirac operator in quenched SU(2) lattice gauge theory with tadpole-improved Symanzik action is studied at finite temperatures in the vicinity of the confinement-deconfinement phase transition defined by the expectation value of the Polyakov line. The value of the chiral condensate obtained from the Banks-Casher relation is found to drop down rapidly at T = Tc, though not going to zero. At Tc' = 1.5 Tc = 480 MeV the chiral condensate decreases rapidly one again and becomes either very small or zero. At T < Tc the distributions of small eigenvalues are universal and are well described by chiral orthogonal ensemble of random matrices. In the temperature range above Tc where both the chiral condensate and the expectation value of the Polyakov line are nonzero the distributions of small eigenvalues are not universal. Here the eigenvalue spectrum is better described by a phenomenological model of dilute instanton - anti-instanton gas.

description: Motivated by the Weak Gravity Conjecture, we uncover an intricate interplay between black holes, BPS particle counting, and Calabi-Yau geometry in five dimensions. In particular, we point out that extremal BPS black holes exist only in certain directions in the charge lattice, and we argue that these directions fill out a cone that is dual to the cone of effective divisors of the Calabi-Yau threefold. The tower and sublattice versions of the Weak Gravity Conjecture require an infinite tower of BPS particles in these directions, and therefore imply purely geometric conjectures requiring the existence of infinite towers towers of holomorphic curves in every direction within the dual of the cone of effective divisors. We verify these geometric conjectures in a number of examples by computing Gopakumar-Vafa invariants.

description: We present photometric and spectroscopic observations of two luminous blue variable (LBV) stars in two extremely metal-deficient blue compact dwarf (BCD) galaxies, DDO 68 with 12+logO/H = 7.15 and PHL 293B with 12+logO/H = 7.72. These two BCDs are the lowest-metallicity galaxies where LBV stars have been detected, allowing to study the LBV phenomenon in the extremely low metallicity regime, and shedding light of the evolution of the first generation of massive stars born from primordial gas. We find that the strong outburst of the LBV star in DDO 68 occurred sometime between February 2007 and January 2008. We have compared the properties of the broad line emission in low-metallicity LBVs with those in higher metallicity LBVs. We find that, for the LBV star in DDO 68, broad emission with a P Cygni profile is seen in both H and He I emission lines. On the other hand, for the LBV star in PHL 293B, P Cygni profiles are detected only in H lines. For both LBVs, no heavy element emission line such as Fe II was detected. The Halpha luminosities of LBV stars in both galaxies are comparable to the one obtained for the LBV star in NGC 2363 (Mrk 71) which has a higher metallicity 12+logO/H = 7.89. On the other hand, the terminal velocities of the stellar winds in both low-metallicity LBVs are high, ~800 km/s, a factor of ~4 higher than the terminal velocities of the winds in high-metallicity LBVs. This suggests that stellar winds at low metallicity are driven by a different mechanism than the one operating in high-metallicity winds.

The regional economic impact of a large-scale, non-profit institution

Publisher: name: University of British Columbia
Year: 2010

description: Regional planners are often faced with having to estimate the various impacts of a new or existing project on the regional economy and to place these estimates in a regional planning context. Their concern is not only with impacts directly attributable to the project itself, but also with the multiplier effect which occurs as a result of successive rounds of respending in the local economy as a result of the project. There are theoretical and practical problems connected with the derivation of the multiplier values. Much of the research in regional economic impact analysis has focused on ways to correct for potential errors in the analysis and on the use of appropriate models for analysis. In this thesis three models are examined: economic base, income expenditure and input-output. Theoretical weaknesses and practical problems associated with each particular model or common to the three models are identified. The relative strengths and weaknesses of the models are evaluated to determine appropriate uses for each. Research has also focused on the particular impacts generated by unique types of projects and on particular regional economies. A growing awareness that there are significant impacts from large, non-profit institutions on regional economies has stimulated an interest in identifying and quantifying these impacts. In this thesis a number of empirical studies utilizing each of the three models to analyse the impact of a large, non-profit institution on a regional economy is reviewed. In the context of this review, the specific advantages and disadvantages of the different models are discussed. The thesis, then, develops a viable methodology through the appropriate use of an existing model to indicate the extent of economic impact of a complex institution on a regional economy. A case study is presented of the regional economic impact of the Pacific National Exhibition complex - a large, non-profit institution in the Lower Mainland of British Columbia. The study demonstrates the economic impact of the PNE Complex by isolating income, employment and expenditure impacts generated in the regional economy by the Complex for the base year 1977. The thesis concludes by considering the role of regional economic impact analysis in the context of regional planning and policy formulation.

description: Electronic current in a nanometer-size rod is theoretically investigated by an eigen-channel decomposition method in nonequilibrium Green's function formalism. Physical properties, such as the local density of electrons and local current, are decomposed into contributions of eigen-channels. We observe that the evanescent modes and nonlinear conductance are enhanced in d-orbital systems, and the structure of the transmission function, local current density, and penetration depth are discussed. The two effects of the ill-contact at electrodes in d-orbital systems, evanescent modes and the nonlinearity of conductance, are regarded as originating in the peak structure of the transmission function of eigen-channels in the energy region between chemical potentials of left and right lead wires.

description: We investigate in more detail the holographic model of a superconductor recently found by Hartnoll, Herzog, and Horowitz [Phys. Rev. Lett. 101, 031601], which is constructed from a condensate of a charged scalar field in AdS_4-Schwarzschild background. By analytically studying the perturbation of the gravitational system near the critical temperature T_c, we obtain the superconducting coherence length proportional to 1/\sqrt{1-T/T_c} via AdS/CFT correspondence. By adding a small external homogeneous magnetic field to the system, we find that a stationary diamagnetic current proportional to the square of the order parameter is induced by the magnetic field. These results agree with Ginzburg-Landau theory and strongly support the idea that a superconductor can be described by a charged scalar field on a black hole via AdS/CFT duality.

description: Human adults excel at inferring and exploiting the causal relations in the world. This certainly contributed to the unprecedented advancements in many areas of life from technology to health and astronomy, not seen in other non-human species. What might have led to this capacity? Is the ability to identify causal relations a uniquely human ability? When does it emerge in human development? Do we represent our environments in fundamentally different ways than other non-human animals? In this thesis, I aimed to expand our understanding concerning these questions. If this is a core human capacity, we may find its precursors in other non-human primates. On the other hand, it may be a late emerging capacity in childhood with the development of language and through cultural input. Then there may not be a continuity with other primates. In my theoretical chapters, I brought together the previous literature to identify the factors that might have facilitated and/or hampered children’s and non-human primates’ performances while they were dealing with causal reasoning tasks. In the light of the challenges presented by this type of research and my goals, I proposed novel paradigms that are suitable to test causal reasoning abilities of young children, chimpanzees and capuchin monkeys. In three studies, I found that by 4-years of age children were able to infer causal relations based on evidence alone. Three-year-olds did not succeed in the tasks but seemed to have benefited from verbal scaffolding provided by the experimenter. The performance of the chimpanzees and capuchins did not lead to decisive conclusions towards the lack or the presence of this capacity. However, the findings highlighted the importance of prior experience in animal learning. The results and their implications are further discussed.

description: A fingerprint region of interest (roi) segmentation algorithm is designed to separate the foreground fingerprint from the background noise. All the learning based state-of-the-art fingerprint roi segmentation algorithms proposed in the literature are benchmarked on scenarios when both training and testing databases consist of fingerprint images acquired from the same sensors. However, when testing is conducted on a different sensor, the segmentation performance obtained is often unsatisfactory. As a result, every time a new fingerprint sensor is used for testing, the fingerprint roi segmentation model needs to be re-trained with the fingerprint image acquired from the new sensor and its corresponding manually marked ROI. Manually marking fingerprint ROI is expensive because firstly, it is time consuming and more importantly, requires domain expertise. In order to save the human effort in generating annotations required by state-of-the-art, we propose a fingerprint roi segmentation model which aligns the features of fingerprint images derived from the unseen sensor such that they are similar to the ones obtained from the fingerprints whose ground truth roi masks are available for training. Specifically, we propose a recurrent adversarial learning based feature alignment network that helps the fingerprint roi segmentation model to learn sensor-invariant features. Consequently, sensor-invariant features learnt by the proposed roi segmentation model help it to achieve improved segmentation performance on fingerprints acquired from the new sensor. Experiments on publicly available FVC databases demonstrate the efficacy of the proposed work.

Critical surface in hot and dense QCD with the vector interaction

description: We discuss the chiral phase transition of hot and dense quark matter. We illustrate that the first-order phase transition is generally favored at high baryon density and the repulsive vector-vector interaction weakens the first-order phase transition. We use the Nambu--Jona-Lasinio model with the Polyakov loop coupling for concreteness. We locate the QCD critical surface on the quark mass plane for various values of the vector coupling constant. We find that, with increasing quark chemical potential, the first-order region in the quark mass plane could shrink for sufficiently large vector coupling. This may be a possible explanation for the recent lattice QCD results by de Forcrand and Philipsen.
