description: Multi-Agent Reinforcement Learning (MARL) algorithms are widely adopted in tackling complex tasks that require collaboration and competition among agents in dynamic Multi-Agent Systems (MAS). However, learning such tasks from scratch is arduous and may not always be feasible, particularly for MASs with a large number of interactive agents due to the extensive sample complexity. Therefore, reusing knowledge gained from past experiences or other agents could efficiently accelerate the learning process and upscale MARL algorithms. In this study, we introduce a novel framework that enables transfer learning for MARL through unifying various state spaces into fixed-size inputs that allow one unified deep-learning policy viable in different scenarios within a MAS. We evaluated our approach in a range of scenarios within the StarCraft Multi-Agent Challenge (SMAC) environment, and the findings show significant enhancements in multi-agent learning performance using maneuvering skills learned from other scenarios compared to agents learning from scratch. Furthermore, we adopted Curriculum Transfer Learning (CTL), enabling our deep learning policy to progressively acquire knowledge and skills across pre-designed homogeneous learning scenarios organized by difficulty levels. This process promotes inter- and intra-agent knowledge transfer, leading to high multi-agent learning performance in more complicated heterogeneous scenarios.

description: Since the Archean, N2 has been a major atmospheric constituent in Earth's atmosphere. Nitrogen is an essential element in the building blocks of life, therefore the geobiological nitrogen cycle is a fundamental factor in the long term evolution of both Earth and Earth-like exoplanets. We discuss the development of the Earth's N2 atmosphere since the planet's formation and its relation with the geobiological cycle. Then we suggest atmospheric evolution scenarios and their possible interaction with life forms: firstly, for a stagnant-lid anoxic world, secondly for a tectonically active anoxic world, and thirdly for an oxidized tectonically active world. Furthermore, we discuss a possible demise of present Earth's biosphere and its effects on the atmosphere. Since life forms are the most efficient means for recycling deposited nitrogen back into the atmosphere nowadays, they sustain its surface partial pressure at high levels. Also, the simultaneous presence of significant N2 and O2 is chemically incompatible in an atmosphere over geological timescales. Thus, we argue that an N2-dominated atmosphere in combination with O2 on Earth-like planets within circumstellar habitable zones can be considered as a geo-biosignature. Terrestrial planets with such atmospheres will have an operating tectonic regime connected with an aerobe biosphere, whereas other scenarios in most cases end up with a CO2-dominated atmosphere. We conclude with implications for the search for life on Earth-like exoplanets inside the habitable zones of M to K-stars.

description: Recycling strange stars to millisecond periods is studied within the framework of general relativity. We employ equations of state of strange quark matter based on the MIT Bag Model, with massive strange quarks and lowest order QCD interactions. The presence of the crust of normal matter is taken into account, with a bottom density assumed to be equal to the neutron-drip one. The calculations are performed by solving the exact 2-D equations for rigidly rotating stationary configurations in general relativity. Evolutionary tracks of accreting strange stars are computed, and their dependence on the initial strange star mass and on the fraction of the angular momentum transferred to the star from the infalling matter, is studied. The differences between recycling strange stars and neutron stars are pointed out.

 Comments. A widely distributed European species. It may have been confused in the collections with the very similar I. czernyi. In the Czech and Slovak Republics, this species has mostly been found in mountains, being relatively common in Malaise trap samples from spruce forests and peat-bogs (e.g. ŠEVČÍK & VONIČKA 2008).
 However, the question of the identity of I. semirufa remains still open, because MORGE (1975) illustrated under this name a slightly different form, with a mostly reddish abdomen. Similarly, a form with orange thorax and three dark lateral stripes on scutum, corresponding to I. czernyi, was illustrated under the name I. signata (Meigen, 1818), which poses a question over their possible synonymy and validity of the latter name. These questions could be definitely solved after examination of the relevant types in the Meigen’s collection and after their association with recent material, suitable for DNA extraction.

description: Background: Breast cancer patients have a lifelong 2–4-fold increased risk of developing a second primary tumor in the contralateral breast compared with the risk for a first primary breast cancer in the general female population. Prevention of contralateral breast cancer (CBC) has received increased attention during recent decades. Here, we summarize and discuss the available literature on drug preventive therapy and CBC. Results: The endocrine-targetting drugs, tamoxifen and aromatase inhibitors are used as standard adjuvant treatment for estrogen receptor (ER)-positive breast cancer. Both are associated with relative risk reductions of CBC of up to 50%, but incur serious side effects. Several prescription drugs originally developed for other purposes, including bisphosphonates, statins, non-steroidal anti-inflammatory drugs, metformin, anti-hypertensives and retinoids, have shown anti-cancer activity in preclinical models. However, results of observational studies on CBC are sparse and inconsistent, with only statins demonstrating promise as preventive agents and a potential treatment option for ER-negative breast cancer patients. Conclusion: Future studies are needed to assess the effect of statins in risk reduction and to identify other drugs with chemopreventive potential against CBC. Eventually, efforts must be directed towards identifying those breast cancer patients likely to benefit most from specific preventive therapies.

description: Identifying academic plagiarism is a pressing task for educational and research institutions, publishers, and funding agencies. Current plagiarism detection systems reliably find instances of copied and moderately reworded text. However, reliably detecting concealed plagiarism, such as strong paraphrases, translations, and the reuse of nontextual content and ideas is an open research problem. In this paper, we extend our prior research on analyzing mathematical content and academic citations. Both are promising approaches for improving the detection of concealed academic plagiarism primarily in Science, Technology, Engineering and Mathematics (STEM). We make the following contributions: i) We present a two-stage detection process that combines similarity assessments of mathematical content, academic citations, and text. ii) We introduce new similarity measures that consider the order of mathematical features and outperform the measures in our prior research. iii) We compare the effectiveness of the math-based, citation-based, and text-based detection approaches using confirmed cases of academic plagiarism. iv) We demonstrate that the combined analysis of math-based and citation-based content features allows identifying potentially suspicious cases in a collection of 102K STEM documents. Overall, we show that analyzing the similarity of mathematical content and academic citations is a striking supplement for conventional text-based detection approaches for academic literature in the STEM disciplines.

Effect of particle inertia on the turbulence in a suspension

description: We propose a one-fluid analytical model for a turbulently flowing dilute suspension, based on modified Navier-Stokes equation with a $k$-dependent effective density of suspension, $ρ_ {eff}(k)$, and an additional damping term $\propto γ_ p(k)$, representing the fluid-particle friction (described by Stokes law). The statistical description of turbulence within the model is simplified by a modification of the usual closure procedure based on the Richardson-Kolmogorov picture of turbulence with a differential approximation for the energy transfer term. The resulting ordinary differential equation for the energy budget is solved analytically for various important limiting cases and numerically in the general case. In the inertial interval of scales we describe analytically two competing effects: the energy suppression due to the fluid particle friction and the energy enhancement during the cascade process due to decrease of the effective density of the small scale motions. An additional suppression or enhancement of the energy density may occur in the viscous subrange, caused by the variation of the extent of the inertial interval due to the combined effect of the fluid-particle friction and the decrease of the kinematic viscosity of the suspensions. The analytical description of the complicated interplay of these effects supported by numerical calculations is presented. Our findings allow one to rationalize the qualitative picture of the isotropic homogeneous turbulence of dilute suspensions as observed in direct numerical simulations.

 Comments. A rare species, only known from several localities in the eastern part of Nearctic Region (SHAW 1952). This is the first record of this remarkable species from the Palaearctic Region. DNA sequence of the barcode region of COI is also provided (Table 3).
 This species possibly represents one of the most primitive and ancient forms of Keroplatidae and can be considered (together with its two extant congeners) as a “living fossil”. Three additional species of Palaeoplatyura were described from the Eocene and Oligocene fossils (EVENHUIS 2006). The exact phylogenetic position of this genus is unknown but preliminary data based on the multigene molecular analysis (Mantič et al., in prep.) suggest that the clade containing Platyura and Paleoplatyura branched rather basally, forming a sister group to all the other taxa of Keroplatidae, except Arachnocampinae.
 This finding also represents a very rare occasion, when a species of Keroplatidae is found in both the Nearctic and Palaearctic Regions. The only known example in the extant keroplatid fauna is Orfelia discoloria (Meigen, 1818), but this may change as soon as a detailed revision of that species group is made. There is also a possibility of a recent introduction by human activities as was demonstrated for some other species of Keroplatidae (CHANDLER & PIJNAKKER 2009). Although the type material of P. johnsoni has not been studied, the identity of the species was established according to the detailed redescription given by SHAW (1952).

description: The rigidity theorem of Witten-Bott-Taubes-Hirzebruch tells us that, if the circle group acts on a closed almost complex (or more generally unitary) manifold whose first Chern class is divisible by a positive integer N greater than 1, then its equivariant elliptic genus of level N is rigid. Applying this to a non-singular compact toric variety, we see that its elliptic genus of level N is rigid if its first Chern class is divisible by N. But, using a vanishing theorem of Hirzebruch, we can show moreover that the genus actually vanishes. In this note we shall extend this result to torus manifolds. In fact, a non-singular complete multi-fan is associated with a torus manifold, and rigidity and vanishing of elliptic genus of level N can be formulated and proved for non-singular complete multi-fans. Some applications on compact non-singular toric varieties with the first Chern class divisible by a large positive integer are given.

Primordialism and mobilization among Syrian-Lebanese in Sydney : a three generational analysis
Creators: name: McKay, James
Publisher: name: The Australian National University
Year: 1980
Subjects: subject: Lebanese Australia
subject: Ethnicity

description: Sociologists are currently polarized over how to account for the alleged ethnic revival around the world, "Primordialists" argue that ethnic resurgence can best be explained by reference to cultural factors and the socialization process. "Mobilizationists" counter with the claim that ethnic traits are manipulated by people in order to gain access to scarce resources. These diametrically opposed theses have been used to explain the phenomenon of "third generation return" among descendants of European immigrants in North America. In the present study, I use data from a case study of Syrian-Lebanese in Sydney to explore the third generation hypothesise In the first chapter I examine the strengths and deficiencies of the primordial and mobilizationist viewpoints and present the rationale for the study. In chapters two and three I discuss the conceptual and methodological approaches to be used. In chapter four I give a synopsis of contemporary Lebanese society, including the major historical forces which have affected its development. In chapter five I examine Syrian- Lebanese migration to Australia in the context of the larger diaspora which occurred in the nineteenth and twentieth centuries. The changes in ethnic organization and ethnic identity among Syrian-Lebanese are analyzed in chapters six and seven. In chapter eight I specifically explore primordial and mobilizationist tendencies among Syrian-Lebanese, Overall, the data does not confirm the mobilizationist thesis and gives only weak support to the primordial argument«, In terms of involvement in and identification with Lebanese institutions, the third generation evidence a pattern of decline rather than return. By using the data and empirical illustrations from other studies, I illustrate the insufficiency of dichotomizing primordial and mobilizationist tendencies. A matrix model is provided in order to demonstrate that mobilization and primordialism are complementary rather than competing ethnic manifestations. Implications of the study at the applied and substantive levels are discussed in the concluding chapter.

description: We consider a two-level atom driven by modulated light and find that complete population inversion can be induced by light without any resonant frequency component. This is in contrast to the familiar case of monochromatic driving in which complete population inversion is only possible with resonant light. This result concerns experimentally realizable systems and hence the effect of spontaneous emission is also considered. We also relate our work to other recent works on quantum double-well. Analogies with the suppression of quantum tunneling and with the low-frequency radiation generation are discussed. By translating the results from the study of the two-level atom to the theory of optical waveguides, we introduce a new geometric representation for analysing the optical state of a single-mode optical coupler. We find that an optical coupler with out-of-phase index modulations can control and suppress the evanescent power transfer between cores. A new type of optical band-pass filter based on the modulated index coupler is proposed.

description: Gamification is not simply a temporary trend but would result in huge changes in life, education and marketing. Under the trend, design researchers should focus on the importance of gamification and apply gamification in the improvement of effective communication. This study aims to apply gamification to website design for facilitating effective communication. Two experimental websites, including a gamification incorporated website and a no-gamification incorporated website, are constructed. Users are recruited to use individual websites. After the website experience, task questions, system usability scale, online questionnaire and retrospective thinking aloud are applied to collect user feedback. The data analyses reveal that ‘gamification incorporated website’ could not promote the usability of websites, while learnability, pleasure, engagement and satisfaction are enhanced. Overall speaking, applying gamification to websites could actually enhance communication efficiency. The gamification design guidelines are eventually proposed to assist future designers in constructing meaningful gamification design with communication efficiency.

description: Close double degenerate binaries are one of the favoured progenitor channels for type Ia supernovae, but it is unclear how many suitable systems there are in the Galaxy. We report results of a large radial velocity survey for double degenerate (DD) binaries using the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surveY - SPY). Exposures taken at different epochs are checked for radial velocity shifts indicating close binary systems. We observed 689 targets classified as DA (displaying hydrogen-rich atmospheres), of which 46 turned out to possess a cool companion. We measured radial velocities (RV) of the remaining 643 DA white dwarfs. We managed to secure observations at two or more epochs for 625 targets, supplemented by eleven objects meeting our selection criteria from literature. The data reduction and analysis methods applied to the survey data are described in detail. The sample contains 39 double degenerate binaries, only four of which were previously known. 20 are double-lined systems, in which features from both components are visible, the other 19 are single-lined binaries. We provide absolute RVs transformed to the heliocentric system suitable for kinematic studies. Our sample is large enough to sub-divide by mass: 16 out of 44 low mass targets (<= 0.45 Msun) are detected as DDs, while just 23 of the remaining 567 with multiple spectra and mass >0.45 Msun are double. Although the detected fraction amongst the low mass objects (36.4 +/- 7.3%) is significantly higher than for the higher-mass, carbon/oxygen-core dominated part of the sample (3.9 +/- 0.8%), it is lower than the detection efficiency based upon companion star masses >= 0.05 Msun. This suggests either companion stars of mass < 0.05 Msun, or that some of the low mass white dwarfs are single.

description: The stationary solutions of the Gross-Pitaevskii equation can be divided in two classes: those which reduce, in the limit of vanishing nonlinearity, to the eigenfunctions of the associated Schrödinger equation and those which do not have linear counterpart. Analytical and numerical results support an existence condition for the solutions of the first class in terms of the ratio between their proper frequency and the corresponding linear eigenvalue. For one-dimensional confined systems, we show that solutions without linear counterpart do exist in presence of a multi-well external potential. These solutions, which in the limit of strong nonlinearity have the form of chains of dark or bright solitons located near the extrema of the potential, represent macroscopically excited states of a Bose-Einstein condensate and are in principle experimentally observable.

The theory of econometric model selection
Creators: name: Sawyer, Kim Russell
Publisher: name: The Australian National University
Year: 1980
Subjects: subject: Econometrics Mathematical models

description: This thesis is concerned with the theory of econometric model selection, an area of fundamental importance in econometrics. The two themes of the document are the approach to developing model selection criteria and the processes for criteria evaluation. Each chapter contains elements of them both. In Chapter 1, principles of model selection are established and the role of inductive inference in model selection is examined. Chapter 2 is an overview of existing criteria, whereby the criteria are classified into three groups according to their application. Chapters 3, 4 and 6 are devoted to aspects of criteria evaluation, namely the conflicts between criteria, the adjustments for dimensionality and various statistical and interpretative properties. In Chapters 3, 5 and 7, new criteria are proposed. These criteria represent extensions and generalisations of existing procedures. The motivation throughout the thesis is for generality, though necessarily, specific illustrations must be made. The objective is to produce a unified structure for model selection which will infer new directions in model selection. This point is pursued in Chapter 8.

Springboard, Roadblock or "Crutch"?: How Transgender Users Leverage Voice Changers for Gender Presentation in Social Virtual Reality

description: Social virtual reality (VR) serves as a vital platform for transgender individuals to explore their identities through avatars and foster personal connections within online communities. However, it presents a challenge: the disconnect between avatar embodiment and voice representation, often leading to misgendering and harassment. Prior research acknowledges this issue but overlooks the potential solution of voice changers. We interviewed 13 transgender and gender-nonconforming users of social VR platforms, focusing on their experiences with and without voice changers. We found that using a voice changer not only reduces voice-related harassment, but also allows them to experience gender euphoria through both hearing their modified voice and the reactions of others to their modified voice, motivating them to pursue voice training and medication to achieve desired voices. Furthermore, we identified the technical barriers to current voice changer technology and potential improvements to alleviate the problems that transgender and gender-nonconforming users face.
Euroattractor: a brief introduction to Iterated Function Systems

description: In this work we propose a definition of an Euroattractor: an attracting invariant measure of a certain iterated functions system (IFS). An IFS is defined by specifying a set of functions, defined in subsets of R^N or in a classical phase space, which act randomly on the initial point, so it may be considered as a generalization of the notion of classical dynamical system. If the functions are sufficiently contracting, there exists an invariant measure of the system, often concentrated on a fractal set. We investigate invariant measures of a certain class of generalized or weakly contracting IFS's.

An Assurance Framework for Independent Co-assurance of Safety and Security

Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: Integrated safety and security assurance for complex systems is difficult for many technical and socio-technical reasons such as mismatched processes, inadequate information, differing use of language and philosophies, etc.. Many co-assurance techniques rely on disregarding some of these challenges in order to present a unified methodology. Even with this simplification, no methodology has been widely adopted primarily because this approach is unrealistic when met with the complexity of real-world system development. This paper presents an alternate approach by providing a Safety-Security Assurance Framework (SSAF) based on a core set of assurance principles. This is done so that safety and security can be co-assured independently, as opposed to unified co-assurance which has been shown to have significant drawbacks. This also allows for separate processes and expertise from practitioners in each domain. With this structure, the focus is shifted from simplified unification to integration through exchanging the correct information at the right time using synchronisation activities.
The pattern and levels of mortality for the 1975-1977 Indonesian sample vital registration project area

description: The aim of this thesis is to estimate the levels and patterns of mortality in each Area of the 1975-1977 Indonesia Sample Vital Registration Project, based on the " observed " and the " adjusted " mortality data by age, where the adjustment factors in each Area are derived for each age group by applying the Chandra-Deming technique, In relation to the adjustment factors by " age " there is a considerable variation between Area, sexes ~a.nd ’years. The higher area for younger ages, whereas the lower factors are for older ages. There are differentials in mortality levels between sexes, urbanrural areas and Survey years, The male mortality exceeds that of females. In most cases, the mortality of rural areas is higher than urban areas, and the mortality of the second year is slightly higher than the third year. There is 2 stilladifference in mortality patterns between sexes and urban-rural areas. But the latter is probably due to the small number of deaths reported in each year. In general, the mortality patterns for both males and urban areas are smoother and more plausible than for those of females and rural areas, respectively. The 1975-1977 SVRP shows a mortality pattern under age 10 very similar to that of West Model at mortality level 14.0 for both sexes. In the middle age range the West Model seems to depict a higher mortality than observed. On the other hand, the reverse is true at old ages. Even if both the systems - Registration and Survey - are deficient, the estimates derived by the application of the Chandra-Deming procedure yield plausible mortality level, a Crude Death Rate for both sexes of 12.1. per thousand population and an expectation of life at birth 49.6 for males and 52.5 for females.
Gravothermal Collapse of Self-Interacting Dark Matter Halos and the Origin of Massive Black Holes

description: A central supermassive black hole (SMBH) with a mass $10^6-10^9 M_\odot$ appears to be a common feature in nearby galaxies and the likely power source in quasars and active galactic nuclei. We demonstrate that the formation of a central black hole is a natural and inevitable consequence of the gravothermal catastrophe in a self-interacting dark matter (SIDM) halo. Through gravothermal evolution driven by collisional relaxation, an SIDM halo will form a massive inner core whose density and velocity dispersion will increase secularly in time. Eventually, the inner core arrives at a relativistic radial instability and undergoes dynamical collapse to a black hole. The initial mass of the black hole will be $10^{-8}-10^{-6}$ of the total mass of the halo. We show that if at formation the overdensity in the SIDM halo is not too large, SMBHs in the observed mass range can form directly in very massive halos following core collapse. Alternatively, with large overdensities, moderate mass halos undergo core collapse to form central seed black holes of intermediate mass, and these holes can then merge and/or accrete to reach the SMBH range. Forming SMBHs by core collapse in SIDM halos requires no baryons, no prior epoch of star formation and no other mechanism of forming black holes seeds.

description: A novel cycloartanol (1) and an acylated Sutherlandioside D (2) together with two known cycloartane derivatives, Sutherlandioside B (3) and Sutherlandioside A (4), were isolated from the aerial parts of Sutherlandia frutescens. The structures of these compounds were established by a combination of 1- and 2-D NMR techniques and further confirmed by high resolution ToF mass spectrometry (HRToFMS). Preliminary biological studies were also conducted to assess the activity of different plant extracts, fractions and compounds on cytokine expression. Compounds 1 and 2 prompted an increase in IL-6 expression while compound 4 showed a reduced IL-6 expression compared to the controls. Compound 1 is an effective suppressor of IL-10 expression. The plant compounds inhibited the expression of the two cytokines, IL-10 and TNFα. The results of the assays suggested that some components in the plant extract influence the immune system by suppressing the expression of IL-6, IL-10 and TNFα.

 Remark. Murray published the article with description of S. lindenii nearly simultaneously in two different journals (MURRAY 1857, 1858). The description was based on an unstated number of specimens of both sexes. Murray had numerous specimens at his disposal (MURRAY 1857: 225); he supplied some of them to other entomologists (MURRAY 1857: 222). The designation of lectotype was published by CHALUMEAU & BROCHIER (2007). Because there is no doubt about the authenticity of the specimen housed in NMPC, we consider it an additional paralectotype.

description: This article empirically examines the effectiveness of commercial diplomacy in contributing to Australia’s merchandise exports and inbound foreign investment with
181 countries over the period 2010-2015. The combined effect of diplomatic entities increases Australian exports by 12.9 per cent and increases inbound foreign investment
by 16.1 per cent compared to countries without representation. Commercial diplomacy is effective when there are impediments to exporting, such as markets being outside the region and having low economic freedom. Commercial diplomacy substantially boosts inbound investment from countries outside and within the region, from emerging and developed markets, and from countries with high levels of economic freedom.
