description: We present an efficient implementation of the solution of the DGLAP equations for single and double parton distributions (PDFs and DPDs). The implemented algorithm is based on the Chebyshev interpolation of these functions. For PDF evolution, our method allows for a higher numerical accuracy using a considerably smaller amount of grid points compared to existing methods. As a consequence of the high interpolation accuracy, operations on PDFs such as differentiation and Mellin convolution can be done in a fast way and with a high level of precision. Furthermore, the DPD evolution is realized to a satisfactory degree of accuracy using an affordable number of points, and allows for two independent renormalization scales for the two partons. For both PDFs and DPDs, DGLAP evolution and flavor matching are implemented up to NNLO.

description: The LHCb collaboration have recently updated their analysis of the resonant $J/\psi p$ mass spectrum in the decay $\Lambda_b^0 \to J/\psi p K^-$, making use of their combined Run 1 and Run 2 data. In the updated analysis, three narrow states, $P_c (4440)^+$, $P_c (4457)^+$,and $P_c (4312)^+$, are observed. The spin-parity assignments of these states are not yet known. We interpret these narrow resonances as compact hidden-charm diquark-diquark-antiquark pentaquarks. Using an effective Hamiltonian, based on constituent quarks and diquarks, we calculate the pentaquark mass spectrum for the complete $SU (3)_F$ lowest $S$- and $P$-wave multiplets, taking into account dominant spin-spin, spin-orbit, orbital and tensor interactions. The resulting spectrum is very rich and we work out the quark flavor compositions, masses, and $J^P$ quantum numbers of the pentaquarks. However, heavy quark symmetry restricts the observable states in $\Lambda_b$-baryon, as well as in the decays of the other weakly-decaying $b$-baryons, $\Xi_b$ and $\Omega_b$. In addition, some of the pentaquark states are estimated to lie below the $J/\psi p$ threshold in $\Lambda_b$-decays (and corresponding thresholds in $\Xi_b$- and $\Omega_b$-decays). They decay via $c \bar c$ annihilation into light hadrons or a dilepton pair, and are expected to be narrower than the $P_c$-states observed. We anticipate their discovery, as well as of the other pentaquark states present in the spectrum at the LHC, and in the long-term future at a Tera-$Z$ factory.

description: LEP precision on electroweak measurements was sufficient not to hamper the extraction of Higgs couplings at the LHC. But the foreseen permille-level Higgs measurements at future lepton colliders might suffer from parametric electroweak uncertainties in the absence of a dedicated electroweak program. We perform a joint, complete and consistent effective-field-theory analysis of Higgs and electroweak processes. The full electroweak-sector dependence of the $e^+e^-\to WW$ production process is notably accounted for, using statistically optimal observables. Up-to-date HL-LHC projections are combined with CEPC, FCC-ee, ILC and CLIC ones. For circular colliders, our results demonstrate the importance of a new $Z$-pole program for the robust extraction of Higgs couplings. At linear colliders, we show how exploiting multiple polarizations and centre-of-mass energies is crucial to mitigate contaminations from electroweak parameter uncertainties on the Higgs physics program. We also investigate the potential of alternative electroweak measurements to compensate for the lack of direct $Z$-pole run, considering for instance radiative return to these energies. Conversely, we find that Higgs measurements at linear colliders could improve our knowledge of the $Z$ couplings to electrons.

description: In classical continuum mechanics, quasi-linear systems of conservation laws can be symmetrized if they admit an additional convex conservation law. In particular, this implies the hyperbolicity of governing equations. For capillary fluids, the internal energy depends not only on the density but also on its derivatives with respect to space variables. Consequently, the governing equations belong to the class of dispersive systems. In that case we propose a symmetric form of governing equations which is different from the classical Godunov -Friedrichs - Lax representation. This new symmetric form implies the stability of constant solutions.

description: Multimode fibers (MMFs) show great promise as miniature probes for sensing, imaging and spectroscopy applications. Different parameters of the fibers, such as numerical aperture, refractive index profile and length, have been already optimized for better performance. Here we investigate the role of the core shape, in particular for wavefront shaping applications where a focus is formed at the output of the MMF. We demonstrate that in contrast to a conventional round-core MMF, a square-core design doesn't suffer from focus aberrations. Moreover, we find that how the interference pattern behind a square-core fiber decorrelates with the input frequency is largely independent of the input light coupling. Finally, we demonstrate that a square core shape provides an on-average uniform distribution of the output intensity, free from the input-output correlations seen in round fibers, showing great promise for imaging and spectroscopy applications.

This is invariant not only under [SL(2,R)]^{3} but also under interchange of the indices A, A' and A''. This triality reveals hitherto hidden discrete symmetries of the Nambu-Goto action.

description: Urban data mining can be identified as a highly potential area that can enhance the smart city services towards better sustainable development especially in the urban residential activity tracking. While existing human activity tracking systems have demonstrated the capability to unveil the hidden aspects of citizens' behavior, they often come with a high implementation cost and require a large communication bandwidth. In this paper, we study the implementation of low-cost analogue sound sensors to detect outdoor activities and estimate the raining period in an urban residential area. The analogue sound sensors are transmitted to the cloud every 5 minutes in histogram format, which consists of sound data sampled every 100ms (10Hz). We then use wavelet transformation (WT) and principal component analysis (PCA) to generate a more robust and consistent feature set from the histogram. After that, we performed unsupervised clustering and attempt to understand the individual characteristics of each cluster to identify outdoor residential activities. In addition, on-site validation has been conducted to show the effectiveness of our approach.

description: We present new spectroscopic and polarimetric observations of the first discovered gravitational lens Q0957+561 obtained with the 6m telescope of the Special Astrophysical Observatory (SAO, Russia). We explore spectropolarimetric parameters of Q0957+561 A,B components to investigate the innermost structure of the quasar, and explore the nature of polarization in lensed quasars. Additionally, we compare their present-day spectral characteristics with previous observations in order to study long-term spectral changes. We analyze spectral characteristics of lensed quasar comparing spectra of A and B images, as well as comparing previously observed image spectra with present-day ones. The polarization parameters of A-B images are compared. We also model the macro-lens influence on the polarization of the images representing the gravitational lens with a singular isothermal elliptical potential. We find that the brightness and SED ratio of components A and B changed during a long period. Polarization in broad lines of components A and B showed that the equatorial scattering cannot be detected in this quasar. We find wavelength-dependent polarization that may be explained as a combination of the polarization from the disc and outflowing material. There is a significant difference between polarization parameters of the A and B images: the B component shows a higher polarization degree and polarization angle. However, both polarization vectors are nearly perpendicular to the observed radio jet projection. It indicates that the polarization in the continuum is coming from the accretion disc. Our simple lensing model of a polarized source showed that macro-lens can cause the observed differences in polarization parameters of Q0957+561 A,B images. Using Mg II broad line and luminosity of component A we estimated that the Q0957+561 black hole mass is M~(4.8-6.1) $10^8$ M$\odot$

Conquest and change : Mongol herding in Xilingol, Inner Mongolia

Year: 2013

description: I examine changing herding practices in Xilingol, Inner Mongolia, contrasting the perspectives of herders with those of local officials and scientists. I also carried out comparative fieldwork in a similar steppe environment in Mongolia. I present a model for research which involves exploring multiple perspectives, including different scales and domains. The model has broad applicability, but was designed in response to pressing problems involving human-environmental interactions. In 1992-1993, from the point of view of many Chinese scientists and policy makers, traditional Mongol herding in Inner Mongolia was in a state of crisis, with widespread land degradation and frequent, crippling natural disasters. Their response involved sweeping changes to what was perceived as an inefficient and unproductive herding system. Xilingol herders were facing an additional challenge with the end of communal herding. In Mongolia, herders were also adjusting to the .end of the collective era. However, political, social and historical factors had contributed to significantly different development agendas each side of the Chinese/Mongolian border. Like the officials and scientists, Xilingol herders recognised the impact of climatic extremes, environmental change, and the potential to increase their standard of living. However, their interpretations differed in several crucial ways. Notably, herders did not perceive the climate as a series of recurrent natural disasters, but rather as a variable, harsh, but well-understood part of their normal environment. From their point of view, traditional herding techniques allowed them to respond to this variability by exploiting environmental heterogeneity. In contrast, scientists either saw herder methods as 'backward', or assumed that traditional skills were no longer practised. I documented a high level of environmental knowledge among herders, involving identification and careful use of resources at different scales. This allowed them to provide for their stock during the normal seasonal cycle, and to respond to more extreme periods. Where their fundamental technique, movement of stock, was limited, herders were frustrated. They were no longer able to avoid the worst excesses of climatic extremes, nor move away from areas where heavy grazing was leading to environmental change. Inner Mongol herders blamed increasing local populations, associated with Han immigration, for the loss of land and restrictions on nomadism. Competing assessments of Mongol herding partly reflect divergent responses to variability. I explore the influence of scale on interpretations of heterogeneity and, more generally, argue for the importance of a critical awareness of scale.

Quaternary mammal faunas and their stratigraphy in the northern Monaro region, southeastern Australia
Creators: name: Davis, Angela C.
Publisher: name: The Australian National University
Year: 1996

description: This thesis documents the history of Quaternary mammalian faunas from the northern Monaro region of the southern highlands of Eastern Australia. The area currently has a cold semi-arid climate and, together with a series of fossil localities of different ages, provides an opportunity to examine the relationships between faunal changes and palaeoenvironments in this part of Australia during the Quaternary. Fossil material from seven localities within the northern Monaro region is described together with the geology of the sites in which they occur. The localities are Pilot Creek, Bunyan Siding, South Bunyan, Bulong, Tannery Creek, Ryries Creek and Rock Flat Creek, all on tributaries of the Murrumbidgee River near Cooma. Detailed stratigraphic studies, incorporating several dating techniques have been employed at the two major fossiliferous deposits, Pilot Creek and Bunyan Siding. A stratigraphic sequence 1s proposed in which the contained faunas are ordered chronologically. The oldest dated mammal fossil-bearing deposit in the region is at Bunyan Siding. It is an alluvial deposit and comprises two fossiliferous Quaternary units, which disconformably overlie Miocene palaeolake sediments of the Bunyan Formation. The Quaternary units are described as two new formations, the Jilliby Folmation and Nestle Brae Formation. They are interpreted as having been formed in a fluvial environment consisting of large and small meandering channels and adjacent floodplains. Dating of the site using palaeomagnetism and optically stimulated luminescence establishes a Middle Pleistocene age (120- 780 ka) for both units. Two local faunas are recognised at Bunyan Siding, the Jilliby Local Fauna and Nestle Brae Local Fauna, each defined and named after the stratigraphic units that contain them. The other major locality, Pilot Creek, is a valley-fill sequence comprising a series of channel cut-and:-fill units and marginal alluvial fans of Late Pleistocene and Holocene ages. Five stratigraphic units are recognised and described in detail including the description of two formations, Pilot Creek and Willow Bank. Each unit contains a local fauna. Fourteen radiocarbon dates enable absolute ages to be placed on some of the units. The oldest fossiliferous unit in the Pilot Creek sequence is the Pilot Creek Formation which has been radiometrically dated at circa 25 ka years BP. The next youngest unit in the sequence is an alluvial fan deposits, QF1 which has been dated at 11 ka. A third unit, the Willow Bank Formation, is a channel-fill unit which truncates both the Pilot Creek Formation and the QF1 unit. Dates from the Willow Bank Formation range from 6 ka to 2 ka. A second alluvial fan unit, QF2 inset into the Pilot Creek Formation, is dated at 4.5 ka. A recent alluvial unit, PESA, is at the top of the sequence. From the stratigraphy of th~ valley units five local faunas have been defined, providing a faunal record in the valley spanning the last 25 ka.

When adjusted to describe precisely the elastic proton-proton scattering data and supplemented with the idea of wounded constituents, the model accounts rather well for the centrality dependence of particle production in the central rapidity region at RHIC energies.

description: The growing interest in the use of clean energy has led to the construction of increasingly large photovoltaic systems. Consequently, monitoring the proper functioning of these systems has become a highly relevant issue.In this paper, automatic detection, and analysis of photovoltaic modules are proposed. To perform the analysis, a module identification step, based on a digital image processing algorithm, is first carried out. This algorithm consists of image enhancement (contrast enhancement, noise reduction, etc.), followed by segmentation of the photovoltaic module. Subsequently, a statistical analysis based on the temperature values of the segmented module is performed.Besides, a graphical user interface has been designed as a potential tool that provides relevant information of the photovoltaic modules.

The emerging system admits separation of variables in the Schrödinger equation and is integrable at the classical level. The first order corrections to the unperturbed spectrum of the ordinary MICZ--Kepler system are calculated. Particularly, the linear Zeeman--effect and effects of MICZ-terms are analyzed. The possible realizations of the system in some quantum dots are considered.

Sensation, perception, and imagery: a study of the Buddhist epistemology of perception with particular reference to the Tattvasamgraha and the Tattvasamgrahanjika
Creators: name: Coseru, Christian
Publisher: name: Canberra, ACT : The Australian National University
Year: 2013

description: This dissertation examines the theory of perception as reflected in the works of two influential Buddhist philosophers, Santarakita's Tattvasamgraha and its commentary by Kamalasila, the Tattvasamgrahapanjika (ca. 750-800 C.E.). In these two works, the authors advance the notion that perception ought to be regarded as the primary source of knowledge and be restricted only to that cognition which is devoid of conceptual thought and non-erroneous. Largely following a model provided by Dharmakirti (ca. 640 C.E.), Santaraksita and Kamalasila adopt two specific viewpoints in defining the perceptual aspects of knowledge: (i) the notion that the domains of language and conceptual thought are coextensive, which can be traced back to the grammarian-philosopher Bhartrhari (ca. 4-5th century C.E.); and (ii) a psychological perspective centred on the notion that direct, unmediated, perception is in fact possible, which finds its origins in the Abhidharma literature. For these Buddhist epistemologists, perception is not only a psychological process to be understood within the framework of classical Abhidharma psychology, but also an epistemic modality for establishing what counts as a valid source of knowledge. The authors' approach is to differentiate non-conceptual cognitions from the mass of cognitive events that is characteristic of ordinary, 'folk,' beliefs about the contents of experience. This differentiation resembles in many ways the methodology adopted by modern psychological investigations into the mechanism of perception and knowledge representation. Adopting a naturalist reading of epistemology, this dissertation argues that Buddhist philosophers did not make a radical distinction between epistemology and the psychological processes of cognition, at least not in the Western sense in which modern epistemology has drifted away from naturalist explanations. Proceeding though a detailed analysis of the textual material, this study concludes that the causal model of perceptual knowledge developed in the two works is intended to provide an empirical foundation for the Buddhist view that all phenomena arise in dependence upon a multitude of causes and conditions and are in a perpetual state of flux.

description: The luminous infrared galaxy Arp299 (IC694+NGC3690) is studied using optical integral field spectroscopy obtained with the INTEGRAL system, together with archival Hubble Space Telescope WFPC2 and NICMOS images. The stellar and ionized gas morphology shows lambda-dependent variations due to the combined effects of the dust internal extinction, and the nature and spatial distribution of the different ionizing sources. The two-dimensional ionization maps have revealed an off-nuclear conical structure of about 4 kpc in length, characterized by high excitation conditions and a radial gradient in the gas electron density. The apex of this structure coincides with B1 region of NGC3690 which, in turn, presents Seyfert-like ionization, high extinction and a high velocity dispersion. These results strongly support the hypothesis that B1 is the true nucleus of NGC3690, where an AGN is located. In the circumnuclear regions HII-like ionization dominates, while LINER-like ionization is found elsewhere. The Halpha emitting sources with ages from 3.3 to 7.2x10^6 years, have masses of between 6 and 680x10^6 Msun and contribute (extinction corrected) about 45% to the bolometric luminosity. The ionized (Halpha) and neutral (NaD) gas velocity fields show similar structure on scales of several hundred to about 1 kpc, indicating that these gas components are kinematically coupled. The kinematic structure is complex and on scales of about 0.2 kpc does not appear to be dominated by the presence of ordered, rotational motions. The large velocity dispersion measured in NGC3690 indicates that this galaxy is the most massive of the system. The low velocity amplitude and dispersion of the interface suggest that the ionized gas is slowly rotating or in a close to quiescent phase.

description: We consider an important generalization of the Dicke model in which multi-level atoms, instead of two-level atoms as in conventional Dicke model, interact with a single photonic mode. We explore the phase diagram of a broad class of atom-photon coupling schemes and show that, under this generalization, the Dicke model can become multicritical. For a subclass of experimentally realizable schemes, multicritical conditions of arbitrary order can be expressed analytically in compact forms. We also calculate the atom-photon entanglement entropy for both critical and non-critical cases. We find that the order of the criticality strongly affects the critical entanglement entropy: higher order yields stronger entanglement. Our work provides deep insight into quantum phase transitions and multicriticality.

description: The use of criteria related to decisional ‘sureness’ in evaluating decision aids and Shared Decision Making processes is questioned on the ground that decisional equipoise is a legitimate outcome of such processes. This occurs in the Decisional Conflict Scale (items 10-12) and its reduced form SURE (item 1), which therefore lack full construct validity for measuring decision quality. The empirical extent of equipoise in a decision aid trial is explored, along with the relationship between the degree of equipoise and decision quality as self-assessed by MyDecisionQuality, a dually-personalised instrument that does not include such ‘sureness’ criteria.

It has assembled a data base of 431 reported torture cases for the period 1963-2010 as well as examined 214 testimonies of state actors, survivors and third parties from Indonesia, Australia, Papua New Guinea, the United States, the United Kingdom and the Netherlands. While the current resurgence of scholarly interests on torture largely focuses on the utilitarian nature of torture as part of the war on terror, the findings of this study take a non-utilitarian turn. First, torture has been deployed strategically by the Indonesian state in Papua as a mode of governance. Second, torture constitutes a spectacle of the sovereign by which the sovereign communicates to a broader audience through the public display of the tortured body. Third, torture has constituted a crime against humanity punishable by both Indonesian and International Human Rights Law. Fourth, the five-decade practice of torture with almost complete impunity has constructed a theatre of torture in which the interactions of survivors, perpetrators, and spectators have produced and reproduced contesting narratives of suffering, domination and witnessing. Based on these four conclusions, peacebuilding in Papua can be reconceptualised as developing a theatre of peacebuilding to transform the theatre of torture. The theatre of peacebuilding model reveals that torture has not always entirely and permanently converted a subject into an ‘abject’. Many survivors not only regain their subjectivity but also their agency. They are able to resist the domination of perpetrators and to take control over their own bodies and histories. In this process of regaining agency, memoria passionis (the memory of suffering) may be beginning to push Papua toward a tipping point that is transforming the theatre of torture to a theatre of peacebuilding. The possibility for this transformation is encapsulated in the idea of establishing a permanent Truth and Reconciliation Commission for Papua (TRCP). Memoria passionis has become a converging point that connects the triangulation of the narratives of suffering, domination and witnessing and inverts the triangulation into a new configuration of ‘revolt, healing and solidarity.’ The whole process of theorising peacebuilding based on the concept of memoria passionis as a remedy to the politics of torture in Papua contributes a novel and distinctively Papuan foundation to the theory and practice of peacebuilding in conflict situations like Papua.

Grappling with another other : Australian studies in Japan

description: Australian studies in Japan provides an example of the dynamics of the construction of area knowledge. The definition and promotion of Australian studies has been shaped by specific Japanese needs, and Australian interests have been intertwined in the process. While individual practitioners' engagement has been framed within the context formed by Japanese and Australian states' concerns, their independent concerns as researchers and as educators have played a significant role in the construction of discourses of Australian studies. Through a case study of Australian studies in Japan as a network of representations of the area known as 'Australia', this thesis considers the meanings created when a specific country or region is represented in area studies education at a university level. The analysis of this thesis is interdisciplinary, deploying the methodological tools from history, cultural studies, and political science. Australian studies in Japan is investigated via textual analysis, using the related written texts and aural texts collected from interviews. The case study of Australian studies in Japan is synthesised with an analysis of the modem and contemporary cultural history of the respective countries and their bilateral relations in the changing international relations. The examination involves in depth investigation of institutions such as school textbooks, government agencies and universities. Integrating the discussion of knowledge/power relations and the questions of national identity in the contexts of Australia and Japan, the thesis examines a variety of approaches to area studies education. Comparisons of Australia and Japan are illuminating for the analysis of representations of the Other and the consequences of colonialism. Each country relates to the experiences and memories of both the colonised and the coloniser. Australia was colonised by Britain, and Japan colonised the neighbouring Asian countries. Indigenous peoples were colonised by the mainstream group within both countries. This thesis demonstrates the ways in which the two countries have common concerns with the question of national identity, vacillating between 'the West' and 'Asia' as totalised imaginary entities through their colonial and postcolonial experiences. This localised case study generates broader intellectual and educational issues, the relevance of which is not limited to Australia and Japan. It is also a study of the consequences of colonialism, the imaginary boundaries of world areas, the location of culture, and national identity in the context of globalisation. As a study of area studies practices at a university level, the thesis addresses issues concerning the internationalisation of higher education, and area studies education in relation to the internationalisation of curriculum in particular. This study itself demonstrates a possible form of area studies with an interdisciplinary approach that deals with trans-area issues.
Life history parameters of the Pacific white-sided dolphin (Lagenorhynchus obliquidens) and its diet and occurrence in the coastal waters of British Columbia

description: Throughout most of their range, Pacific white-side dolphins (Lagenorhynchus obliquidens) inhabit pelagic waters, or the continental shelf and slope. In recent years, however, their abundance has increased markedly in the nearshore waters of British Columbia, and the species is likely the most numerous cetacean in the region. In this study I examined the timing of this increase, and ecological and population factors that may have contributed to it. No systematic population censuses of Pacific white-sided dolphins have been conducted in British Columbia. However, because the species is gregarious, active at the surface, and interacts with vessels, many mariners take note of it. I surveyed mariners on the timing and locations of their sightings, and received 165 written responses. They reported relatively few sightings between 1978 and 1984, and frequent sightings after 1985. I estimated life-history parameters for Pacific white-sided dolphins using data taken from animals that were killed accidentally or deliberately during fisheries, or for scientific reasons, or recovered as stranded carcasses. The average age at first reproduction was 8.5 years for females, gestation was 12.0-12.2 months, and the calving interval was 4.67 years (S.E.=1.81). The rate of population increase was estimated to be between 0.94-1.02/yr, reflecting a stationary population. This suggests that the increase in abundance in British Columbia cannot be explained by population growth alone, and must have resulted, at least partly, from a movement of dolphins from other areas. To examine the potential role of prey in the movement of dolphins, I examined their diet in inshore waters, using prey fragment sampling (n=64) and stomach content analyses (n=11). Prey consisted mostly of herring (Clupea harengus), salmon (Oncorhynchus spp.), cod (Family Gadidae), and shrimp (Order Decapoda). Previous studies found that in offshore areas, dolphins feed on mesopelagic fish and squid, thus dolphins moving inshore may be exploiting new food resources. The inshore movement of dolphins appears to coincide with a 'regime shift', characterised by a change in water temperatures. It is suggested that this may have caused changes in the relative abundance of the prey of Pacific white-sided dolphins.

description: The southwestern (SW) part of the Galactic H II region M17 contains an obscured ionization front that is most easily seen at infrared and radio wavelengths. It is nearly edge-on, thus offering an excellent opportunity to study the way in which the gas changes from fully ionized to molecular as radiation from the ionizing stars penetrates into the gas. M17 is also one of the very few H II regions for which the magnetic field strength can be measured in the photodissociation region ( PDR) that forms the interface between the ionized and molecular gas. Here we model an observed line of sight through the gas cloud, including the H+, H0 (PDR), and molecular layers, in a fully self-consistent single calculation. An interesting aspect of the M17 SW bar is that the PDR is very extended. We show that the strong magnetic field that is observed to be present inevitably leads to a very deep PDR, because the structure of the neutral and molecular gas is dominated by magnetic pressure, rather than by gas pressure, as previously had been supposed.We also show that a wide variety of observed facts can be explained if a hydrostatic geometry prevails, in which the gas pressure from an inner X-ray hot bubble and the outward momentum of the stellar radiation field compress the gas and its associated magnetic field in the PDR, as has already been shown to occur in the Orion Nebula. The magnetic field compression may also amplify the local cosmic-ray density. The pressure in the observed magnetic field balances the outward forces, suggesting that the observed geometry is a natural consequence of the formation of a star cluster within a molecular cloud.

Can we select multiple colours simultaneously? Evidence for serial processing from left to right

description: Some studies find evidence that multiple features can be simultaneously selected (e.g. Adamo et al., 2008), but Lo and Holcombe (2013) found that multiple-feature selection was achieved only with sufficient exposure duration. Here, participants monitored four simultaneous streams of letters, two to the left of fixation and two to the right, presented at a rate of 5.3 items/second. One stream on each side was a target stream of letters in a pre-cued colour, while the other was a stream of distractors presented in a different colour. At a variable time, circles appeared around the streams, and participants were asked to report the letters of the pre-cued colour for each side. We used mixture modelling to estimate efficacy, the proportion of trials where the participants reported a letter around the time of the circles. When observers monitored the same colour for both targets, efficacy was approximately 60%. When participants monitored different colours for each target, efficacy for the left was approximately 50%, whereas that for the right was as low as 26%. The results suggest that at least for these brief-exposure conditions, simultaneously selecting multiple colours is difficult and the colour on the left side is usually selected first.
Eigen-adaptation and distributed representations of 2-D phase, energy, scale and orientation in spatial vision

description: Distributed representations are fault tolerant, orthogonal representations derived from the signal autocorrelation function (ACF) are both efficient & optimal. Here we examine orthogonal representations via the Riesz Transform and derive a distributed representation to include a 2D phase, that allows one to pass smoothly across both isotropic and orientation tuned filters. We posit that orthogonal representations underpin visual adaptation effects, and by taking the tilt after-effect as an example, demonstrate how this can be so.
