The paradox of inaccurate mimicry

description: Many species gain a selective benefit through mimicry by converging on the phenotypic attributes of another unrelated species which has resulted in many examples of mimics bearing a striking resemblance to their model. It is assumed that natural selection should drive the evolution of accurate mimicry while eliminating inaccurate mimics from the population. Paradoxically, there are many instances of mimics that inaccurately resemble their model. The many hypotheses proposed to explain the occurrence of inaccurate mimics are reviewed, with no one hypothesis providing a complete explanation. This thesis explored a mostly overlooked hypothesis, the perfecting hypothesis that predicts that inaccurate mimics are in an intermediate stage in a transition toward accurate mimicry, using ant-mimicking spiders as a model. To investigate this concept, three methods of quantifying mimic accuracy in ant-mimicking spiders were evaluated for their efficacy. Following this, the phylogenies for two subfamilies of ant-mimicking spiders were reconstructed to map the distribution of mimic accuracy and the traits involved in ant mimicry and estimate ancestral states. The results indicate that mimic accuracy, and traits such as the constriction of the body, evolve via an incremental process, supporting the prediction of the perfecting hypothesis and further elucidating potential evolutionary processes in mimicry systems.

description: Pesticide dust concentrations in homes have been previously associated with occupational and home/garden use of pesticides, hygiene practices, and other factors. This study evaluated the relationship between self-reported use of 2,4-dichlorophenoxyacetic acid (2,4-D) and house dust concentrations and these factors in the Biomarkers of Exposure and Effect in Agriculture (BEEA) Study, a molecular epidemiologic study of farmers in Iowa and North Carolina. The vacuum dust from the homes of 35 BEEA participants was analyzed for the presence of 2,4-D. Participants provided detailed information on occupational and home/garden pesticide use during the past 12 months and reported household characteristics via questionnaires. Linear regression models were used to examine the association between 2,4-D concentrations and four exposure metrics for occupational use in the last 12 months (yes/no, days since last use, days of use, intensity-weighted days of use), home/garden use (yes/no), as well as several household characteristics. 2,4-D was detected in all homes and was used occupationally by 54% of the participants. In a multi-variable model, compared to homes with no occupational or home/garden 2,4-D use reported in the past 12 months, concentrations were 1.6 (95% confidence interval (CI): 0.5, 4.9) times higher in homes with low occupational 2,4-D use (intensity-weighted days < median) and 3.1 (95% CI: 1.0, 9.8) times higher in homes of participants with high use (≥median intensity-weighted days) (p-trend = 0.06). Similar patterns were observed with other occupational metrics. Additionally, 2,4-D dust concentrations were non-significantly elevated (relative difference (RD) = 1.8, 95% CI: 0.5, 6.2) in homes with home/garden use and were significantly lower in homes that did not have carpets (RD = 0.20, 95% CI: 0.04, 0.98). These analyses suggest that elevated 2,4-D dust concentrations were associated with several metrics of recent occupational use and may be influenced by home/garden use and household characteristics.

description: Magnetic properties of the spin-1/2 XXZ Heisenberg cuboctahedron are examined using exact numerical diagonalization depending on a relative strength of the exchange anisotropy. While the Ising cuboctahedron exhibits in a low-temperature magnetization curve only one-third magnetization plateau, the XXZ Heisenberg cuboctahedron displays another four intermediate plateaux at zero, one-sixth, one-half and two-thirds of the saturation magnetization. The novel magnetization plateaux generally extend over a wider range of magnetic fields with increasing of a quantum ($xy$) part of the XXZ exchange interaction. It is shown that the XXZ Heisenberg cuboctahedron exhibits in a vicinity of all magnetization jumps anomalous thermodynamic behavior accompanied with an enhanced magnetocaloric effect.

From atomic energy to nuclear science: a history of the Australian Atomic Energy Commission

Subjects: Other education not elsewhere classified

description: Nuclear energy was once seen as a possible answer to man's energy needs, but it could also be used to produce the most destructive weapons known. The initial research into the phenomenon of nuclear fission was done at university laboratories in Europe on the eve of the Second World War. This war led to the development of the first nuclear weapons. After the war, many nations wanted access to both the weapons and the source of cheap power that the process of nuclear fission provided. Australia was one such nation. -- The Australian Government wanted nuclear energy to help develop the dry interior of the continent. There were many in Government who also wanted nuclear weapons. This work focuses on the Australian pursuit of nuclear energy for peaceful uses. The achieve this aim an organisation was established which would train scientists and engineers in nuclear science and technology. This organisation, the Australian Atomic Energy Commission, is the subject of this thesis. -- This work will examine the political influences that governed the Commission in its function and scientific research paths. Specifically, it will examine how successive governments caused the Commission to cancel projects, change the direction of its research, attempted (on several occasions) to amalgamate the Commission with the CSIRO, forcing the organisation into uranium mining and finally abolishing it and replacing it with a new organisation, the Australian Nuclear Science and Technology Organisation. Government interference would continue with this new organisation which had its entire board dismissed in 1993. -- The Commission was essentially a scientific and engineering organisation and hence this thesis will also consider a number of projects with which the Commission was involved such as the Beryllium Project, uranium exploration and mining, the uranium enrichment programs, the purchase of two nuclear reactors, the Synroc project, and the ill-fated Jervis Bay power reactor project. Other projects which were started in the early days of the Commission, the neutron diffraction work and the isotope production projects, will be mentioned in passing. Both these projects require a more detailed appraisal than is possible in this thesis.

description: We perform two-dimensional axially symmetric radiation-hydrodynamic simulations to assess the impact of outflows and radiative force feedback from massive protostars by varying when the protostellar outflow starts, the ratio of ejection to accretion rates, and the strength of the wide angle disk wind component. The star formation efficiency, i.e. the ratio of final stellar mass to initial core mass, is dominated by radiative forces and the ratio of outflow to accretion rates. Increasing this ratio has three effects: First, the protostar grows slower with a lower luminosity at any given time, lowering radiative feedback. Second, bipolar cavities cleared by the outflow are larger, further diminishing radiative feedback on disk and core scales. Third, the higher momentum outflow sweeps up more material from the collapsing envelope, decreasing the protostar's potential mass reservoir via entrainment. The star formation efficiency varies with the ratio of ejection to accretion rates from 50% in the case of very weak outflows to as low as 20% for very strong outflows. At latitudes between the low density bipolar cavity and the high density accretion disk, wide angle disk winds remove some of the gas, which otherwise would be part of the accretion flow onto the disk; varying the strength of these wide angle disk winds, however, alters the final star formation efficiency by only +/-6%. For all cases, the opening angle of the bipolar outflow cavity remains below 20 degree during early protostellar accretion phases, increasing rapidly up to 65 degree at the onset of radiation pressure feedback.

Evolution of suicide terrorism: a case study of Pakistan
Creators: name: Iqbal, Khuram
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This study offers the first empirically grounded analysis of suicide terrorism in Pakistan and puts forth the argument that single-factor theories fall short of explaining the emergence and phenomenal rise of this deadly tactic. A multi-level analysis of Pakistani human bombs reveal that suicide terrorism is caused by multiple factors with perceived effectiveness, vengeance, poverty and religious fundamentalism playing a varying role at the individual, organisational and environmental levels. Nationalism and resistance to foreign occupation appears as the least relevant factors behind suicide terrorism in Pakistan. The findings of this study are based on a multi-level analysis of suicide bombings, incorporating primary and secondary data. In this study, the author also decodes personal, demographic, economic and marital characteristics of Pakistani human bombs. On average, Pakistani suicide bombers are the youngest but the deadliest in the world, and more than 71 per cent of their victims are civilians. Earlier concepts of a weak link linking terrorism with poverty and illiteracy do not hold up against the recent data gathered on the post-9/11 generation of fighters in Pakistan (in suicidal and non-suicidal categories), as the majority of fighters from a variety of terrorist organisations are economically deprived and semi-literate. The majority of Pakistani human bombs come from rural backgrounds, with very few from major urban centres. Suicide bombings in Pakistan remain a male-dominated phenomenon, with most bombers single men. Demographic profiling of Pakistani suicide bombers, based on a random sample of 80 failed and successful attackers, dent the notion that American drone strikes play a primary role in promoting terrorism in all its manifestations. The study concludes that previous scholarly attempts to explain suicide bombings are largely based on Middle Eastern data, thus their application in the case of Pakistan can be misleading. The Pakistani case study of suicide terrorism demonstrates unique characteristics, hence it needs to be understood and countered through a context-specific and multi-level approach.

description: The desire of building developers to leave surfaces of cross laminated timber constructions in multi-story housings visible for the building user, leads to acoustic challenges with the flanking sound transmission that cannot be controlled by means of wall linings. As a result, controlling flanking sound transmission by measures directly in the joint is getting increasingly important. The main parameter for describing the vibrational power transmission over a junction between structural elements is the vibration reduction index Kij. For this quantity, some planning values are spread over numerous publications. None of the currently available data sources represents a holistic view on the building acoustic performance of on the market available products for elastic interlayers and fasteners which are used in wall-ceiling junctions. The following paper shows results of measurements of vibration reduction indices of different configurations of a wall-ceiling joint in a test facility. Different elastic interlayers and fasteners were investigated. The vibration reduction indices spread from 16db to 26dB as a function of the joint configuration and the load applied on the joint. The measurement results obtained are discussed and the essential parameters for influencing the flanking sound transmission are worked out and quantified.

description: Due to the high spontaneous emission coupled into the resonance mode in metallic nanolasers, there has been a debate concerning the coherence properties of this family of light sources. The second-order coherence function can unambiguously determine the nature of a given radiation. In this paper, an approach to measure the second-order coherence function for broad linewidth sources in the near-infrared telecommunication band is established based on a modified Hanbury Brown and Twiss configuration. Using this set-up, it is shown that metallic coaxial and disk-shaped nanolasers with InGaAsP multiple quantum well gain systems are indeed capable of generating coherent radiation.
Oplax actions and enriched icons with applications to coalgebroids and quantum categories

Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis is a formal treatise around the concept of bialgebroids and the alternative ways to describe them. There are two characterizations of bialgebroids due to Szlachányi which play a central role in our investigation; one as cocontinuous opmonoidal monads on the category of two-sided R-modules, and another as certain skew monoidal structures on the category of right R-modules. Lack and Street internalised Szlachányi's characterization to a suitable monoidal bicategoryM. In this way, they obtain an equivalence between opmonoidal monads on the enveloping monoidale induced by a biduality and right skew monoidales whose unit has a right adjoint in M. Such equivalence provides a characterization of the quantum categories deﬁned by Day and Street. In the ﬁrst two chapters, we focus on the simpler structure of a coalgebroid. In a monoidal bicategory M, coalgebroids generalise as opmonoidal arrows between enveloping monoidales. Chapter 2 has two main results. The ﬁrst one, following Lack and Street's methods, is a characterisation of opmonoidal arrows between enveloping monoidales which leads to the new concept of oplax actions with respect to a skew monoidale. The second result involves the study of comodules. Comodules for coalgebroids are classically deﬁned as comodules for the underlying coring; and in a monoidal bicategory M, opmonoidal arrows and oplax actions each admit a notion of comodule. We prove that these three ways to deﬁne comodules are equivalent. The equivalence between opmonoidal arrows and oplax actions mentioned above is analogous to that of opmonoidal monads and right skew monoidales. We formalise this statement in Chapter 3, and show along the way that monads of oplax actions are right skew monoidales whose unit has a right adjoint. The last chapter focuses on a diﬀerent characterisation of bialgebroids: Moerdijk proved that a monad on a monoidal category is an opmonoidal monad if and only if the category of algebras has a monoidal structure such that the forgetful functor is strong monoidal. In other words, the 2-category OpMon of monoidal categories, opmonoidal functors, and opmonoidal natural transformations has Eilenberg-Moore objects for monads. We generalise this theorem in two directions: a multi-object version, and a version enriched in a monoidal bicategory. For the multi-object version, we replace OpMon with the 2-category Icon of bicategories, oplax functors, and icons. And for the version enriched in a monoidal bicategory M, we replace Icon with a bicategory Icon(M) of M-enriched bicategories, M-enriched oplax functors, and M-enriched icons. At this level of generality, the theorem asserts that the bicategory Icon(M) has Eilenberg-Moore objects for monads if M does.

Utopias, dystopias, and abjection: pathways for society's others in George Eliot's major fictions
Creators: name: Lee, Sung-Ae
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Within a framework based on Mikhail Bakhtin's dialogism and Julia Kristeva's theory of abjection, this thesis investigates how Utopian impulses are manifested in George Eliot's novels. Eliot's utopianism is presented first by a critique of dystopian elements in society and later by placing such elements in a dialogic relationship with utopian ideas articulated by leading characters. Each novel includes characters who are abjected because they have different ideas from the social norms, and such characters are silenced and expelled because society evaluates these differences in terms of its gender, class and racial prejudices. Dystopia is thus constituted as a resolution of the conflict between individual and society by the imposition of monologic values. Dialogic possibilities are explored by patterned character configurations and by the cultivation of ironical narrators' voices which enfold character focalization within strategic deployment of free indirect discourse. -- Eliot's early works, from Scenes of Clerical Life to Silas Marner, focus their dystopian elements as a critique of a monologic British society intolerant of multiple consciousnesses, and which consigns "other" voices to abjection and thereby precludes social progress by rejecting these "other" voices. In her later novels, from Romola to Daniel Deronda, Eliot presents concrete model utopian societies that foreshadow progressive changes to the depicted, existing society. Such an imagined society incorporates different consciousnesses and hence admits abject characters, who otherwise would have been regarded as merely transgressive, and thus silenced or eliminated. Abjected characters in Eliot's fiction tend also to be utopists, and hence have potential for positively transforming the world. Where they are depicted as gaining agency, they also in actuality or by implication bring about change in society, the nation and the wider world. -- An underlying assumption is that history can be changed for the better, so that utopian ideals can be actualized by means of human agency rather than by attributing teleological processes to supernatural forces. When a protagonist's utopian impulses fail, it is both because of dystopian elements of society and because of individual human weaknesses. In arguably her most utopian works, Romola and Daniel Deronda, Eliot creates ideal protagonists, one of whom remains in the domestic sphere because of gender, and another who is (albeit voluntarily) removed from British society because of his race/class. However, Romola can be seen as envisaging a basis for female advancement to public life, while Daniel Deronda suggests a new world order through a nationalism grounded in multiculturalism and a global utopianism.

description: We report on the results from a large observational campaign on the bare Seyfert galaxy Ark 120, jointly carried out in 2014 with XMM-Newton, Chandra, and NuSTAR. The fortunate line of sight to this source, devoid of any significant absorbing material, provides an incomparably clean view to the nuclear regions of an active galaxy. Here we focus on the analysis of the iron fluorescence features, which form a composite emission pattern in the 6$-$7 keV band. The prominent K$α$ line from neutral iron at 6.4 keV is resolved in the Chandra High-Energy Transmission Grating spectrum to a full-width at half maximum of 4700$^{+2700}_{-1500}$ km s$^{-1}$, consistent with an origin from the optical broad-line region. Excess components are detected on both sides of the narrow K$α$ line: the red one (6.0$-$6.3 keV) clearly varies in strength in about one year, and hints at the presence of a broad, mildly asymmetric line from the accretion disk; the blue one (6.5$-$7.0 keV), instead, is likely a blend of different contributions, and appears to be constant when integrated over long enough exposures. However, the Fe K excess emission map computed over the 7.5 days of the XMM-Newton monitoring shows that both the red and the blue features are actually highly variable on timescales of $\sim$10$-$15 hours, suggesting that they might arise from short-lived hotspots on the disk surface, located within a few tens of gravitational radii from the central supermassive black hole and possibly illuminated by magnetic reconnection events. Any alternative explanation would still require a highly dynamic, inhomogeneous disk/coronal system, involving clumpiness and/or instability.

description: Expansion microscopy (ExM) is a recently developed technique that allows for the resolution of structures below the diffraction limit by physically enlarging a hydrogel-embedded facsimile of the biological sample. The target structure is labeled and this label must be retained in a relative position true to the original, smaller state before expansion by linking it into the gel. However, gel formation and digestion lead to a significant loss in target-delivered label, resulting in weak signal. To overcome this problem, we have here developed an agent combining targeting, fluorescent labeling and gel linkage in a single small molecule. Similar approaches in the past have still suffered from significant loss of label. Here we show that this loss is due to insufficient surface grafting of fluorophores into the hydrogel and develop a solution by increasing the amount of target-bound monomers. Overall, we obtain a significant improvement in fluorescence signal retention and our new dye allows the resolution of nuclear pores as ring-like structures, similar to STED microscopy. We furthermore provide mechanistic insight into dye retention in ExM.

description: The spatiotemporal oscillation patterns of the proteins MinD and MinE are used by the bacterium E. coli to sense its own geometry. Strikingly, both computer simulations and experiments have recently shown that for the same geometry of the reaction volume, different oscillation patterns can be stable, with stochastic switching between them. Here we use particle-based Brownian dynamics simulations to predict the relative frequency of different oscillation patterns over a large range of three-dimensional compartment geometries, in excellent agreement with experimental results. Fourier analyses as well as pattern recognition algorithms are used to automatically identify the different oscillation patterns and the switching rates between them. We also identify novel oscillation patterns in three-dimensional compartments with membrane-covered walls and identify a linear relation between the bound Min-protein densities and the volume-to-surface ratio. In general, our work shows how geometry sensing is limited by multistability and stochastic fluctuations.

description: Efficient and fast manipulation of antiferromagnets has to date remained a challenging task, hindering their application in spintronic devices. For ultrafast operation of such devices, it is highly desirable to be able to control the antiferromagnetic order within picoseconds—a timescale that is difficult to achieve with electrical circuits. Here, we demonstrate that bursts of spin-polarized hot-electron currents emerging due to laser-induced ultrafast demagnetization are able to efficiently excite spin dynamics in antiferromagnetic Mn2Au by exerting a spin-transfer torque on femtosecond timescales. We combine quantitative superdiffusive transport and atomistic spin-model calculations to describe a spin-valve-type trilayer consisting of Fe|Cu|Mn2Au. Our results demonstrate that femtosecond spin-transfer torques can switch the Mn2Au layer within a few picoseconds. In addition, we find that spin waves with high frequencies up to several THz can be excited in Mn2Au.

Although Grignard conditions turned out to be insufficient due to the steric and electronic effects of silyl groups causing a decreased nucleophilicity of the metalated intermediates, stepwise lithium–halogen exchange yields complex mixtures of polysilylated compounds FeC10DMSnH10−n (n = 10, 9, 8) including the targeted decasilylated ferrocene. These mixtures were successfully separated allowing a systematic study of silylation effects on ferrocene by XRD, CV, NMR and UV/vis spectroscopy supported by DFT calculations. The findings were used to develop a high-yielding and simple preparation method to generate a tenfold substituted overcrowded ferrocene, FeC10DMS8Me2.

description: Studies on the penetration of toxicologically or pharmaceutically relevant substances through the skin and, more specifically, through the stratum corneum (s.c.) often rely on the well-established method of tape stripping. Tape stripping involves the removal of skin layers by means of adhesive tape, which is usually followed by quantification of dermally applied substances in these layers. However, the amount of s.c. removed by each individual tape strip is still a matter of scientific debate. While some studies imply that the amount of s.c. adhering to each tape strip decreases with increasing depth into the s.c., others observed a constant removal rate. All these studies rely on the quantification of the amount of s.c. captured on individual or pooled tape strips. Here, we present an approach whereby we measured the amount of s.c. remaining on excised porcine skin in the process of tape stripping. Staining and bloating of the s.c. allowed to measure its thickness and to count individual s.c. layers, respectively. Histologically, we show that the s.c. remaining on the skin decreased linearly as a function of strips taken. We found that each tape strip removes about 0.4 µm of s.c., which corresponds to approximately one cellular layer. With a high coefficient of determination (r2 > 0.95), we were able to linearly correlate the thickness of the remaining s.c., the number of remaining cell layers and the number of tape strips applied. Furthermore, we elaborate on possible reasons for the discrepancies reported in the scientific literature regarding the amount of s.c. removed by each tape strip.

description: Generalization bounds are a critical tool to assess the training data requirements of Quantum Machine Learning (QML). Recent work has established guarantees for in-distribution generalization of quantum neural networks (QNNs), where training and testing data are drawn from the same data distribution. However, there are currently no results on out-of-distribution generalization in QML, where we require a trained model to perform well even on data drawn from a different distribution to the training distribution. Here, we prove out-of-distribution generalization for the task of learning an unknown unitary. In particular, we show that one can learn the action of a unitary on entangled states having trained only product states. Since product states can be prepared using only single-qubit gates, this advances the prospects of learning quantum dynamics on near term quantum hardware, and further opens up new methods for both the classical and quantum compilation of quantum circuits.
Trust enhanced security framework for mobile ad hoc wireless networks

description: The advent of wireless communication and the proliferation of handheld devices have significantly advanced the growth of nomadic communications. Capability of these handheld mobile devices to self-organise themselves on fly in the absence of an infrastructure and to extend their communications beyond their wireless radio range have potentially led to the development of Mobile Ad hoc Networks (MANET). Security is one of the most indispensable research areas and plays a central role in determining the success of civilian and commercial mobile ad hoc networks. Unfortunately, mobile nodes struggle to enlist trusted intermediaries for communication with various destinations since trusted intermediaries are a prerequisite to keep those communications alive and free from active attacks. Although few integrated security systems exist for the MANETs, a two-layered (prevention and detection-reaction systems) trust-enhanced security architecture is yet to be seen for the MANETs to the best of our knowledge. The two-layered approach is so required for the prevention and detection-reaction systems to complement each other to deliver a trustworthy, secure, and an operational routing layer amidst the inherent issues. -- Therefore this thesis, (a) focuses on the systematic study of the security threats and attacks and, adversaries in the MANETs and accordingly the analysis of the strength of solutions that have been proposed within different categories of security systems, (b) proposes novel techniques to meet the shortcomings of proposed security solutions and thence to develop a realistic two-layered T̲rust E̲nhanced security A̲rchitecture for the M̲ANETs (TEAM). These novel techniques include, (a) an obligation-based fellowship model to motivate cooperation among the mobile nodes, (b) S̲ecure M̲ANET R̲outing with T̲rust I̲ntrigue (SMRTI) that resolves the limitations harboured by related trust models and capitalises all the evidence that are available within the limitations of the M̲ANET for making better routing decisions and, (c) a new secure routing protocol known as Scasec. Furthermore, fellowship model is extended to defend flooding attacks in the MANETs that support anonymous communications. Similarly, SMRTI is extended to incorporate subjective logic with a focus to resolve the notion of uncertainty in the trust relationships established between newly-joining and existing mobile nodes. Finally, the better performance results of all these proposed techniques are demonstrated using varied simulation scenarios.

description: We consider the interaction of atomic hydrogen with an intense laser field within the strong-field approximation. By using a Faddeev-like formalism, we introduce a new perturbative series in the binding potential of the atom. As a first test of this new approach, we calculate the electron energy spectrum in the very simple case of a photon energy higher than the ionisation potential. We show that by contrast to the standard perturbative series in the binding potential obtained within the strong field approximation, the first terms of the new series converge rapidly towards the results we get by solving the corresponding time-dependent Schroedinger equation.

description: Aims. We investigate the impact of updated atmospheric mean opacity input values on modelled transit radius and the distribution of interior layer mass fractions. Methods. We developed and applied a coupled interior-atmosphere model. Our straightforward semi-grey calculation of atmospheric temperature enables us to perform thousands of model realisations in a Monte Carlo approach to address potential degeneracies in interior and atmospheric mass fraction. Our main constraints are planetary mass and radius from which our model infers distributions of the internal structure of exoplanetary classes ranging from Super-Earth to Mini-Neptune. We varied the relative masses of gas, envelope, mantle, and core layers subject to constraints on the bulk density from observations, and investigated the effect of updating atmospheric mean opacities. Results. First, we validate our model output with observed temperature profiles for modern Neptune. We can reproduce the basic features in the middle atmosphere but not the temperature inversion in the upper layers, which is likely because our model lacks aerosol heating. Calculated interiors are generally consistent with modern Neptune. Second, we compare with the well-studied object GJ 1214 b and obtain results that are broadly consistent with previous findings; they suggest correlations between modelled gas, water, and core mass fractions, although these are generally weak. Updating the opacities leads to a change on the order of a few percent in the modelled transit radius. This is comparable in magnitude to the planned accuracy of the PLATO data for planetary radius, suggesting that the opacity update in the model is important to implement.

description: It has recently been possible to synthesize ordered assemblies composed of magnetic superatomic clusters Ni9Te6(PEt3)8 separated by C60 and study their magnetic behavior. We have carried out theoretical studies on model systems consisting of magnetic superatoms separated by non-magnetic species to examine the evolution in magnetic response as the nature of the magnetic superatom (directions of spin quantization), the strength of isotropic and anisotropic interactions, the magnetic anisotropy energy, and the size of the assembly are varied. We have examined square planar configurations consisting 16, 24 and 48 sites with 8, 12 and 24 magnetic superatoms respectively. The magnetic atoms are allowed 2 or 5 orientations. The model Hamiltonian includes isotropic exchange interactions with second nearest neighbor ferromagnetic and nearest neighbor antiferromagnetic couplings and anisotropic Dzyaloshinskii-Moriya interactions. It is shown that the inclusion of Dzyaloshinskii-Moriya interaction that cause spin canting is necessary to get qualitative response as observed in experiments.

description: The power of the helicity formalism has been appreciated recently from its application to the massless case, where plenty of formal aspects of multi-legs amplitudes have been derived. However, in order to extend the formalism to the realistic cases, such as the electroweak Standard Model and QCD with massive quarks, some extra inputs are needed. We discuss first the formalism needed to evaluate amplitudes expressed with the modern notation for massive fermions and vectors based on a thorough treatment of Proca vector fields. Then, we present some examples of elementary processes where it is shown how the formalism leads to tremendous simplifications, these include 2-body decays $Z\to ff$, $h\to ff$ and $h\to W^{-}W^{+}$ as well as the 3-body decay $h\to V f'\bar{f}$.
