description: Electroweak boson-tagged jet measurements provide a promising experimental channel to accurately study the physics of jet production and propagation in dense QCD medium. In this talk, we present theoretical predictions for the nuclear-induced attenuation of the differential cross section for isolated photon-tagged and $\rm Z^0$-tagged jet production in heavy ion collisions, and provide theoretical interpretations to the recent LHC data. We demonstrate quantitatively the significance of collisional and radiative energy losses, as revealed in the strong momentum asymmetry $dσ/dx_{VJ}$ and nuclear modification $\rm I_{AA}$ in central lead-lead reactions.

Frequency Coverage Properties of a Uniform Shrinkage Prior Distribution

Year: 2016
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: A uniform shrinkage prior (USP) distribution on the unknown variance component of a random-effects model is known to produce good frequency properties. The USP has a parameter that determines the shape of its density function, but it has been neglected whether the USP can maintain such good frequency properties regardless of the choice for the shape parameter. We investigate which choice for the shape parameter of the USP produces Bayesian interval estimates of random effects that meet their nominal confidence levels better than several existent choices in the literature. Using univariate and multivariate Gaussian hierarchical models, we empirically show that the USP can achieve its best frequency properties when its shape parameter makes the USP behave similarly to an improper flat prior distribution on the unknown variance component.

description: The E3 ubiquitin ligase NEDD4 has been intensively studied in processes involved in viral infections, such as virus budding. However, little is known about its functions in bacterial infections. Our investigations into the role of NEDD4 in intracellular bacterial infections demonstrate that Mycobacterium tuberculosis and Listeria monocytogenes, but not Mycobacterium bovis BCG, replicate more efficiently in NEDD4 knockdown macrophages. In parallel, NEDD4 knockdown or knockout impaired basal macroautophagy/autophagy, as well as infection-induced autophagy. Conversely, NEDD4 expression promoted autophagy in an E3 catalytic activity-dependent manner, thereby restricting intracellular Listeria replication. Mechanistic studies uncovered that endogenous NEDD4 interacted with BECN1/Beclin 1 and this interaction increased during Listeria infection. Deficiency of NEDD4 resulted in elevated K48-linkage ubiquitination of endogenous BECN1. Further, NEDD4 mediated K6- and K27- linkage ubiquitination of BECN1, leading to elevated stability of BECN1 and increased autophagy. Thus, NEDD4 participates in killing of intracellular bacterial pathogens via autophagy by sustaining the stability of BECN1.

description: Robots have the potential to be a game changer in healthcare: improving health and well-being, filling care gaps, supporting care givers, and aiding health care workers. However, before robots are able to be widely deployed, it is crucial that both the research and industrial communities work together to establish a strong evidence-base for healthcare robotics, and surmount likely adoption barriers. This article presents a broad contextualization of robots in healthcare by identifying key stakeholders, care settings, and tasks; reviewing recent advances in healthcare robotics; and outlining major challenges and opportunities to their adoption.

The character of evangelism in Colonial Melbourne: activism, initiative, and leadership

Subjects: Other education not elsewhere classified

description: Chapter 1 sets the context by pointing out two contradictory contentions about the Christian history of C olonial Melbourne: the contention that Christianity has been of minimal or no significance; the tradition that Christianity is of fundamental importance to the history, and the civilisation of Melbourne. This thesis highlights a significant part of the tradition: evangelism. -- The second chapter, states the thesis: the Character of Evangelism in Colonial Melbourne was distinguished by (1) activism; the evangelicals were energetic and intentional. (2) It lacked nothing in initiative. (3) Both of these characteristics were due to outstanding leadership among the evangelical men of Melbourne who earnestly longed for, worked for, and saw, revival. The chapters that follow argue this by focusing on key individuals and events that were the evangelistic responses to the perceived challenges of the age. -- The Port Phillip Era (1835-1850) saw the Religious Foundations of Colonial Melbourne laid. The faith of the early men of Melbourne - orthodox, creedal and theist - was foundational to the nascent civilisation. Evangelism, mainly by the Methodists, was present from the beginning. -- The 1850s, the gold rush years, saw much evangelism, mainly by the Methodists. The Melbourne City Mission, which combined evangelistic fervour and social care, was founded. The world-wide 1858-60 revival was felt in Melbourne. The independent evangelist Henry Varley is introduced. -- The 1860s was a decade of continued enthusiasm. The other churches pulled their weight, but the Methodists continued in the van. -- The 1870s was a decade of initiative. The Anglican Hussey Burgh Macartney engaged in and facilitated evangelism and overseas missions, introduced the deeper-life movement to mainland Australia, and began The Missionary at Home and Abroad. The Methodist W H Fitchett began the Southern Cross. Henry Varley returned, and the Melbourne United Evangelistic Association was formed. -- Evangelism flourished in the 'Marvellous Melbourne' Decade (the 1880s), highlighted by the Evangelisation Society of Victoria, the 1888 Centennial Mission, and Varley's third visit. -- The crowning moments of 1890-1903 were the Rev John MacNeil and the (prayer) Band, the visit of Hudson Taylor, the Rev George Grubb and the Geelong Convention, the 1902 Torrey-Alexander Mission, and the 1903 visit of John R Mott. -- The concluding chapter summarizes the argument under the heads: the religious culture of Melbourne, the evangelical men of Melbourne, the evangelists, their methods, and their motivation.
Coherent photon manipulation in interacting atomic ensembles

description: Coupling photons to Rydberg excitations in a cold atomic gas yields unprecedentedly large optical nonlinearities at the level of individual light quanta, where the formation of nearby dark-state polaritons is blocked by the strong interactions between Rydberg atoms. This blockade mechanism, however, realizes an inherently dissipative nonlinearity, which limits the performance of practical applications. In this work, we propose a new approach to strong photon interactions via a largely coherent mechanism at drastically suppressed photon losses. Rather than a polariton blockade, it is based on an interaction induced conversion between distinct types of dark-state polaritons with different propagation characteristics. We outline a specific implementation of this approach and show that it permits to turn a single photon into an effective mirror with a robust and continuously tuneable reflection phase. We describe potential applications, including a detailed discussion of achievable operational fidelities.

description: It is well known that, in the context of General Relativity, some spacetimes, when described by a congruence of comoving observers, may consist in a distribution of a perfect (non-dissipative) fluid, whereas the same spacetime as seen by a "tilted"' (Lorentz-boosted) congruence of observers, may exhibit the presence of dissipative processes. As we shall see, the appearence of entropy producing processes are related to the tight dependence of entropy on the specific congruence of observers. This fact is well illustrated by the Gibbs paradox. The appearance of such dissipative processes, as required by the Landauer principle, are necessary, in order to erase the different amount of information stored by comoving observers, with respect to tilted ones.

description: Abstract The study investigated the effect of ethnochemistry teaching approach on achievement and retention of senior secondary students in standard mixture separation techniques. A sample of 198 students from six purposively selected secondary schools out of a population of 3,706 Senior Secondary I students from Ohaozara Local Government Area of Ebonyi State, Nigeria was used for the study. The study adopted nonequivalent quasi-experimental research design. The instrument used for data collection was Separation Techniques Achievement Test (STAT) with the reliability value of 0.84 using Kuder-Richardson (KR-21). Two research questions and two null hypotheses guided the study. The research questions were answered using Mean and Standard Deviation scores while the hypotheses were tested at 0.05 level of significance using Analysis of Covariance (ANCOVA). The study revealed that students taught mixture separation techniques using ethnochemistry approach had significantly higher mean achievement scores than those taught using discussion method [F(1,197)=405.07, P<0.05]and students taught standard mixture separation techniques using ethnochemistry approach had significantly higher mean retention scores than those taught using discussion method [F(1,197)=293.00, P<0.05]. It was recommended that chemistry teachers’ trainee should be trained on the use of ethnochemistry approach and serving teachers should be encouraged to use ethnochemistry.

description: After a successful core collapse supernova (CCSN) explosion, a hot dense proto-neutron star (PNS) is left as a remnant. Over a time of twenty or so seconds, this PNS emits the majority of the neutrinos that come from the CCSN, contracts, and loses most of its lepton number. This is the process by which all neutron stars in our galaxy are likely born. The emitted neutrinos were detected from SN 1987A and they will be detected in much greater numbers from any future galactic CCSN. These detections can provide a direct window into the properties of the dense matter encountered inside neutron stars, and they can affect nucleosynthesis in the mate- rial ejected during the CCSN. In this chapter, we review the basic physics of PNS cooling, including the basic equations of PNS structure and neutrino diffusion in dense matter. We then discuss how the nuclear equation of state, neutrino opacities in dense matter, and convection can shape the temporal behavior of the neutrino signal. We also discuss what was learned from the late time SN 1987A neutrinos, the prospects for detection of these neutrinos from future galactic CCSNe, and the effects these neutrinos can have on nucleosynthesis.

description: In this study, improving senior secondary students’ retention in electrolysis using Collaborative Concept Mapping Instructional Strategy (CCMIS) was examined. A sample of 189 students from six selected secondary schools out of a population of 5,114 Senior Secondary I students from Ardo-Kola Local Government Area of Taraba State, Nigeria was used for the study. Non-equivalent quasi-experimental research design was adopted. The instrument used for data collection was Electrolysis Retention Test (ERT) with the reliability value of 0.78 using Kuder-Richardson. Two research questions and three null hypotheses guided the study. Mean and Standard Deviation scores were used to answer the research questions while Analysis of Covariance (ANCOVA) was used to test the null hypotheses. The study revealed that there is significant difference in the mean retention scores between students taught electrolysis using CCMIS and discussion method in favour of CCMIS; [F(1,97) =6.300, P<0.050]. No significant difference was found in the mean retention scores between male and female students taught electrolysis using CCMIS; [F(1,97) =6.300, P>0.050]. It also found no significant interaction effect between methods and gender on the mean retention scores of students in electrolysis; [F(1,197) =.318, P>0.050]. It was recommended among others that CCMIS should be adopted while teaching electrolysis since it has been proved to be a viable option in enhancing students’ retention capacity regardless of their gender.
Characterizing Large Strain Elasticity of Brittle Elastomeric Networks by Embedding Them in a Soft Extensible Matrix

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Here, the general design and properties of new multiple network elastomers with an exceptional combination of stiffness, toughness, and elasticity are reported. In this paper, it is reported in more detail how the increase in strain at break resulting from the toughening can be used to provide great insight in the large strain properties of otherwise brittle acrylic well crosslinked networks. The networks have been prepared by sequences of polymerization and swelling with monomers. The parameters that have been varied are the nature of the base monomers and the degree of crosslinking of the first network. Here, the small strain properties, equilibrium swelling, and large strain properties in uniaxial tension are characterized. It is shown here that the large strain properties of the multiple networks are quantitatively controlled by the large strain properties of the stretched first network which acts as a percolating filler, while the small and intermediate properties are controlled by the entanglement density which can be largely superior to that of homogeneous networks. Different brittle and prestretched elastomer networks are embedded at a low volume fraction in a soft extensible matrix. The increase in toughness of the final material is directly controlled by the nonlinear elastic properties of the prestretched network and its volume fraction, providing a general design rule for tough soft materials

Roles of complementary colours in colour perception
Creators: name: Pridmore, Ralph William
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Complementary colours have been studied in science for over 300 years but little is known of their role in colour vision. Complementary colours are defined as a pair of colour stimuli which, with appropriate complementary wavelengths and ratios of radiant powers, admix a selected white (e.g. that of the illuminant). The thesis aim is to find and describe roles of complementary colours in colour perception. Only one role is generally accepted in the scientific literature: a colorimetric role in colour mixture and matching. A second role, in chromatic induction, was widely accepted until (erroneously) usurped 50 years ago by the opponent colours theory of chromatic induction. This thesis stemmed from signs that the visual system structures various visual functions from complementary colours. -- Complementarism is shown to structure ten functions. For six of the functions, math models are formulated from complementary colours. The first three, closely related, papers describe three roles in colour constancy (see Appendix: Definitions), hue cycle structure, and hue cycle relative wavelength metric. Paper 1 describes complementary wavelengths' central role in a spectral mechanism of colour constancy, where constant hue and its complementary constant hue form parallel straight lines. Paper 2 establishes the roles of complementary colours in forming hue cycle structure and its wavelength-based metric. Dominant wavelength is extended into the nonspectrals/purples to form a relative wavelength scale over the whole cycle. Paper 3 utilises this scale to extend Paper 1's spectral mechanism of colour constancy into the nonspectrals to complete the global mechanism. Paper 4 argues that chromatic induction is governed by complementary colours rather than opponent colours. Paper 5 formulates math models for six roles, in chromatic induction, wavelength discrimination, uniform hue, spectral sensitivity, saturation, and chromatic adaptation, from the ratio of either complementary wavelength intervals or of complementary powers; a seventh role, in three-dimensional color discrimination, is described. The total eleven varied roles (including the known colorimetric role) have a wide influence over the visual process from cones to cortex. These discrete roles indicate an overall role of complementary colours is structural, in shaping functions to a trimodal framework (RGB peaks and complementary CMY troughs), whose implicit purpose is to adapt functions to the illuminant. Thus, it is concluded the general role is colour constancy.
Topological Sources of Soliton Mass and Supersymmetry Breaking

description: We derive the Smarr formulae for two five-dimensional solutions of supergravity, which are asymptotically R^(1,3)xS^1; in particular, one has a magnetic bolt in its center, and one is a two-center solution. We show for both spacetimes that supersymmetry - and so the BPS-bound - is broken by the holonomy and how each topological feature of a space-like hypersurface enters Smarr's mass formula, with emphasis on the ones that give rise to the stated violation of the BPS-bound. In this light, we question if any violating extra-mass term in a spacetime with such asymptotics is only evident in the ADM mass while the Komar mass per se tries to preserve BPS. Finally, we derive the cohomological fluxes for each situation and examine in a more general fashion how the breaking of supersymmetry - and so the BPS-bound violation - is associated with their topologies. In the second (and more complicated) scenario, we especially focus on the compact cycle linking the centers, and the contribution of non-vanishing bulk terms in the mass formula to the breaking of supersymmetry.

Emittance Growth in Linear Induction Accelerators

description: The Dual-Axis Radiographic Hydrotest (DARHT) facility uses bremsstrahlung radiation source spots produced by the focused electron beams from two linear induction accelerators (LIAs) to radiograph large hydrodynamic experiments driven by high explosives. Radiographic resolution is determined by the size of the source spot, and beam emittance is the ultimate limitation to spot size. Some of the possible causes for the emittance growth in the DARHT LIA have been investigated using particle-in-cell (PIC) codes, and are discussed in this article. The results suggest that the most likely source of emittance growth is a mismatch of the beam to the magnetic transport, which can cause beam halo.

Environmental migration in the Pacific: resettlement and legal frameworks for protection

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Environmental migration is not a new phenomenon in the Pacific. Pacific Islanders have moved across great distances in the past and environmental threats have been among the triggers. However, long-term climatic processes suggest that environmental migration will increase over the coming years. The Pacific region, with its low-elevation island nations, is particularly vulnerable to environmental challenges, and is predicted to be among the areas where the adverse effects of environmental change will be felt most keenly. This thesis examines the role of law and legal policy towards migration and protection of environmental migrants in the Pacific. Its aim is twofold: to identify admission opportunities for Pacific environmental migrants in Pacific Rim countries, and to explore avenues for protecting the culture and identity of resettled migrants in their host communities. The study is a multidisciplinary thesis by publication, comprising seven articles that have been published or accepted for publication. The first two explore migration opportunities, while the other five are case studies corresponding to what the thesis claims to be attempted (Nauru), failed (Bikini) and successful (Banaba) cases of resettlement in the Pacific. The thesis adopts a range of methodologies, including doctrinal analysis, archival work and qualitative interviews. The thesis concludes that, absent an international regime, the most pragmatic approach for dealing with environmentally-displaced peoples in the Pacific is through a liberal implementation of domestic migration policies. Additionally, the promotion of minority rights and the protection of the collective identity of environmental migrants in their host societies are critical components of successful long-term resettlement

description: In the era of cloud computing and data-driven applications, it is crucial to protect sensitive information to maintain data privacy, ensuring truly reliable systems. As a result, preserving privacy in deep learning systems has become a critical concern. Existing methods for privacy preservation rely on image encryption or perceptual transformation approaches. However, they often suffer from reduced task performance and high computational costs. To address these challenges, we propose a novel Privacy-Preserving framework that uses a set of deformable operators for secure task learning. Our method involves shuffling pixels during the analog-to-digital conversion process to generate visually protected data. Those are then fed into a well-known network enhanced with deformable operators. Using our approach, users can achieve equivalent performance to original images without additional training using a secret key. Moreover, our method enables access control against unauthorized users. Experimental results demonstrate the efficacy of our approach, showcasing its potential in cloud-based scenarios and privacy-sensitive applications.

description: Dirac structures are geometric objects that generalize both Poisson structures and presymplectic structures on manifolds. They naturally appear in the formulation of constrained mechanical systems. In this paper, we show that the evolution equa- tions for nonequilibrium thermodynamics admit an intrinsic formulation in terms of Dirac structures, both on the Lagrangian and the Hamiltonian settings. In absence of irreversible processes these Dirac structures reduce to canonical Dirac structures associated to canonical symplectic forms on phase spaces. Our geometric formulation of nonequilibrium thermodynamic thus consistently extends the geometric formulation of mechanics, to which it reduces in absence of irreversible processes. The Dirac structures are associated to the variational formulation of nonequilibrium thermodynamics developed in Gay-Balmaz and Yoshimura [2016a,b] and are induced from a nonlinear nonholonomic constraint given by the expression of the entropy production of the system.

description: I published some solutions a time ago to Goldbach Conjecture, Collatz Problem and Twin Primes; but I noticed that there were some serious logic voids to explain the problems. After that I made some corrections in my another article; but still there were some mistakes. Even so, I can say it easily that here I brought exact solutions for them out by new methods back to the drawing board.

description: The research was on the effect of hands-on activities on achievement and retention of senior secondary chemistry students in stoichiometry. A sample of 292 students from eight purposively selected secondary schools out of a population of 8,381 SS II students from zone C of Benue State, Nigeria was used for the study. The study adopted quasi-experimental research design. The instrument used for data collection was Stoichiometry Achievement Test (SAT) with the reliability value of 0.92 using Pearson Product Moment Coefficient. Two research questions and two null hypotheses guided the study. The research questions were answered using Mean and Standard Deviation scores while the hypotheses were tested at 0.05 level of significance using Analysis of Covariance (ANCOVA). The study revealed that students taught stoichiometry using hands-on activities had significantly higher mean achievement scores than those taught using demonstration method (F=555.374, P(0.0001<0.05) and students taught stoichiometry using hands-on activities had significantly higher mean retention scores than those taught using demonstration method (F=117.523, P(0.0001<0.05). It was recommended that since hands-on activities method was found to be an effective method for improving students’ achievement and retention in stoichiometry; Chemistry teacher’s trainee should be trained on the use of hands-on activities and serving teachers should be encourage to use i

description: The two-point complex coherence function constitutes a complete representation for scalar quasi-monochromatic optical fields. Exploiting dynamically reconfigurable slits implemented with a digital micromirror device, we report on measurements of the complex two-point coherence function for partially coherent light scattering from a `scene' comprising one or two objects at different transverse and axial positions with respect to the source. Although the intensity shows no discernible shadows in absence of a lens, numerically back-propagating the measured complex coherence function allows estimating the objects' sizes and locations -- and thus the reconstruction of the scene.

description: The research was on the effect of hands-on activities on senior secondary chemistry students’ achievement and retention in stoichiometry in Zone C of Benue State. The moderating effect of gender was also examined. The study adopted the pretest, posttest, control group, quasi-experimental research design. The instrument used for data collection was Stoichiometry Achievement Test (SAT) with the reliability value of 0.92 using Pearson product moment coefficient. The target population of this study was 8381 which was the population of SSII chemistry students in study area. A sample of 292 students comprising 158 boys and 134 girls drawn from 8 schools within 4 Local Government Areas (LGA) out of 9 LGA in the zone selected using multi-stage sampling techniques. Four research questions and six null hypotheses guided the study. The research questions were answered using Mean and Standard Deviation scores while the hypotheses were tested at 0.05 level of significance using Analysis of Covariance (ANCOVA). The study revealed that students taught stoichiometry using hands-on activities had significantly higher mean achievement scores than those taught using demonstration method F=555.374, P(0.0001<0.05) and students taught stoichiometry using hands-on activities had significantly higher mean retention scores than those taught using demonstration method F=117.523, P(0.0001<0.05). There was no significant difference between the mean achievement scores of male and female students taught stoichiometry using hands-on activities. Based on the findings, it was recommended among others that Chemistry teacher’s trainee should be trained on the use of hands-on activities and serving teachers should use it. Hands-on activities teaching method is not gender sensitive therefore both male and female students should be involved in hands-on activities to enhance their achievement and retention in stoichiometry.

description: From its ‘modern’ pollen-analytical beginnings, the science of what we now term palynology wrestled with terminology and sought an acceptable name for the discipline. Starting in 1943, the mimeographed Pollen Analysis Circular, edited from Ohio by Paul Sears, led to discussion of the content, organisation and naming of a developing discipline. This came to a head in 1944 with Ernst Antev's plea for ‘The Right Word’ and the suggestion of the word ‘palynology’ from the Cardiff duo of Harold Hyde and David Williams. In the search for a suitable term, Hyde consulted Cardiff-based Irish classicist Leopold Richardson who advised against the word palynology and suggested six alternatives. Hyde, however, was wedded to the term palynology and, in the interests of euphony and ‘hankering after my own offspring’, was seemingly able to overcome Richardson's scholarly objections by argument. Hyde and Williams defined palynology as ‘the study of pollen and other spores and their dispersal, and applications thereof’. This was considered an advance because alternative terms such as pollen analysis, pollen statistics and pollen science did not include the application or interpretation of pollen evidence. The term palynology quickly found acceptability within the pages of the Pollen Analysis Circular and subsequently received an airing in Nature. Once palynology was adopted by the influential Swede Gunnar Erdtman, it was rapidly accepted by the palaeoecological community.
The late-career and transition to retirement phases for school leaders in the 21st century: the aspirations, expectations, experiences and reflections of late-career and recently-retired principals in New South Wales (2008-2012)

description: This study explores the relationships between late career, ageing and work for school principals in the 21st century; and the implications of those relationships for educational jurisdictions, professional associations and individual principals. -- Organizational psychologists Beehr and Bennett (2007) believe that "as the baby-boomer population ages, the number of retirees and the proportion of the society they represent will almost certainly increase to levels never before seen. Thus it is now more important than ever to understand retirement" (p.277). In Australia the record retirement level is creating a drain on experience in the workforce whilst simultaneously resulting in a shrinking working-sector supporting an increasing retired-sector. These trends are acknowledged as political, economic and social issues of national significance. -- The education community is not exempt. This is especially so in the area of educational leadership. Internationally, educational jurisdictions are dealing with potential principal shortages as an unprecedented number of principals approach retirement age. The situation is exacerbated in some cases by a low number of aspirants. At a time of increasing public awareness and high-level political sensitivity about school systems, the capacity of educational jurisdictions to have effective leadership succession strategies is extremely important. The relationship between the principal retirement bulge and effective school leadership beckons closer investigation. -- To investigate what the phenomenon of retirement actually means for "baby boomer" principals, this study draws on the experiences, feelings and beliefs of school principals in New South Wales (Australia). The phenomenon of retirement is explored as a continuum rather than an event, with the parameters stretching from principals' late-career to their recently-retired phase. The journey (or transition) along that pathway provides the background context for the study. The perceptual meaning and nature of retirement are explored through an investigation of the aspirations, expectations, reflections and experiences of late-career and recently-retired principals. The study adopts a grounded theory approach (with the data gathered driving the research) and uses quantitative and qualitative methodologies. -- Research in this area is relatively recent and scarce, particularly in the educational leadership domain. With the inter-face between rapidly ageing societies and work the 21st century not yet clear, the findings provide valuable information for educational leadership theory, for educational policy makers, for principal professional associations, and for individual principals.
