description: This study evaluated a novel perinatal health education program, entitled Preparing for Caring, teaching infant touch and handling skills for those who care for babies. Sensitive, attuned, and responsive interactions between caregivers and infants are crucial for the healthy development of foundational brain architecture. Research has confirmed that evidence-based perinatal health programs have the potential to increase the caregiver’s satisfaction and self-efficacy, to reduce anxiety about caring for a newborn, to increase the caregiver’s capacity to form an attachment bond with the infant, and to promote the infant’s health and development. The present study built upon evidence that nurturing touch is positively associated with brain development which positively impacts behavior, cognition, and the health trajectories of children from low-income urban and minority families who are more likely to experience disparities in lifespan health, including increased infant and maternal mortality. Caring and stimulus-rich environments, especially those promoted in intergenerational programs such as Early Head Start, offer “the most compelling evidence” for producing positive changes in both parents and children. The current study, providing perinatal parenting education within an urban Early Head Start (EHS) setting, was hypothesized to effect changes in parents that will positively influence their parenting skills during a critical period of neural and emotional growth and thereby positively influence their children’s development. Mixed-methods data were collected from EHS early childcare educators, parents and community caregivers, administrators, and the program developers. Analyses evaluated program fidelity, specifically in its translation to a new population and setting; identified barriers to and facilitators of implementation of the program; identified which program components were most likely to be accepted and incorporated into daily use by participants; and conducted and shared the results of a pilot study on what an impact evaluation of what participating in this program might look like for key outcomes (including caregiver self-efficacy and maternal self-esteem).

Subjects: Morelia viridis • snake • ontogenetic colour change • tropics • rainforest

description: The green python Morelia viridis is a most striking animal. Individuals are born either brick red or bright yellow and both colours change to green as adults. These colours and the remarkable colour change have long made them of interest to biologists and in demand for the pet trade. Despite this interest nothing is known of their distribution, biology or ecology in the wild. Here I address this knowledge gap by presenting results from the first detailed study of the species, at Iron Range on eastern Cape York Peninsula, Australia.¶...
Mobility Metrics for Routing in MANETs
Creators: name: Xu, Sanlin
Publisher: name: The Australian National University
Year: 2007
Subjects: MANETs, mobile ad hoc networks, mobility metrics, Markov chain model, route caching, link caching, cache timeout, minimum routing overhead, hierarchy routing, k-hop clustering, clusterhead selectionmetric, optimal cluster density

description: A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without the need for base stations or any other pre–existing network infrastructure. In a peer-to-peer fashion, mobile nodes can communicate with each other by using wireless multihop communication. Due to its low cost, high flexibility, fast network establishment and self-reconfiguration, ad hoc networking has received much interest during the last ten years. However, without a fixed infrastructure, frequent path changes cause significant numbers of routing packets to discover new paths, leading to increased network congestion and transmission latency over fixed networks. Many on-demand routing protocols have been developed by using various routing mobility metrics to choose the most reliable routes, while dealing with the primary obstacle caused by node mobility. ¶ In the first part, we have developed an analysis framework for mobility metrics in random mobility model. ... ¶ In the second part, we investigate the mobility metric applications on caching strategies and hierarchy routing algorithm. ...
An Empirical Examination of Physical Asset Expenditure Announcements in Australia: Growth Opportunities, Free Cash Flow and Capital Market Monitoring
Creators: name: Yeoh, Daniel Ghee Chong
Publisher: name: The Australian National University
Year: 2000

description: This thesis examines the stock market price variations associated with physical asset expenditure announcements in Australia. With the exception of the study of Chen and Ho (1997) in Singapore, most capital expenditure studies in other markets investigate the announcement effects associated with changes in budgeted capital expenditures. The fact that there is almost never any firm level capital budget announcement in Australia presents a unique opportunity to examine individual physical asset expenditure announcements. ¶ Three primary hypotheses pertaining to growth opportunities, free cash flow theory, and the capital market monitoring argument are developed and tested. ... ¶ This thesis makes the following contributions. First, this thesis presents the initial empirical evidence concerning physical asset expenditure announcements in Australia. Second, the thesis shows that the quality of a firm's growth opportunities is the key factor in determining the direction and magnitude of abnormal returns around physical asset expenditure announcements. These results also suggest that the equity market in Australia reacts to physical asset expenditure announcements which contain information pertaining to growth opportunities rather than the relative size of the physical asset expenditure transactions to firm value. Third, support for the capital monitoring argument and the free cash flow theory is not strong. Fourth, all other control variables are found to be insignificant in explaining the stock market variations once market to book ratio is included in the regression. Fifth, the results suggest that prior research which fails to segregate market to book ratio and free cash flow proxy into finer partitions may have possibly underestimated the market to book and the free cash flow effects.
Circuits of migration: a structural analysis of migration in Peninsular Malaysia
Creators: name: Young, Mei Ling
Publisher: name: The Australian National University
Year: 2004
Subjects: Malaysia • internal migration • structural change • urbanization • regional development

description: The main thesis of this study is that migration is an integral component of the major processes of structural change in a country. As such, migration should not be studied in isolation from the historical and evolving patterns of development of the country. In their specific forms and magnitudes, migration processes are patterned movements of human populations within and between territorial units. The important point to stress here is that these movements are a response to, and at the same time, conditions the economic and social forces which affect significant sections of a community

subject: Modernism (Aesthetics)

description: My dissertation, titled Hanging-Together: Kant, Goethe, and the Theory of Aesthetic Modernism, observes that many of the composers, artists, and writers working in the early twentieth century developed theories of aesthetic coherence (Zusammenhang) that contradict the canonical interpretation of the period in terms of discontinuity and fragmentation. I show that the modernists drew on Goethe’s morphology in order to conceive of the inner coherence of the work of art as neither an aggregate (in which the parts precede the whole), nor as a system (in which an idea of the whole precedes its parts), but as a morphological nexus of formal variations. My thesis is that aesthetic modernism negates the ‘outer coherence’ of the work of art in order to reveal its ‘inner coherence,’ and that this morphological concept of inner coherence does not entail the totalizing ideal maintained by the poetic and aesthetic tradition from Aristotle to Kant. I develop this argument over the course of five chapters: the first examines Kant’s concept of systematic unity; the second focuses on Goethe’s critical response to Kant’s philosophy of nature; while the last three trace Goethe’s morphology through the theoretical reflections of a modernist composer, painter, and writer—Arnold Schönberg, Wassily Kandinsky, and Alfred Döblin. What emerges is a theory of aesthetic modernism that takes into account the historical specificity of the period without reducing its significance to the ‘break’ it supposedly effects with tradition.

description: Universality of correlation functions obtained in parametric random matrix theory is explored in a multi-parameter formalism, through the introduction of a diffusion matrix $D_{ij}(R)$, and compared to results from a multi-parameter chaotic model. We show that certain universal correlation functions in 1-d are no longer well defined by the metric distance between the points in parameter space, due to a global topological dependence on the path taken. By computing the density of diabolical points, which is found to increases quadratically with the dimension of the space, we find a universal measure of the density of diabolical points in chaotic systems.

description: PSR J1227$-$6208 is a 34.53-ms recycled pulsar with a massive companion. This system has long been suspected to belong to the emerging class of massive recycled pulsar-ONeMg white dwarf systems such as PSR J2222$-$0137, PSR J1528$-$3146 and J1439$-$5501. Here we present an updated emission and timing analysis with more than 11 years of combined Parkes and MeerKAT data, including 19 hours of high-frequency data from the newly installed MeerKAT S-band receivers. We measure a scattering timescale of 1.22 ms at 1 GHz with a flat scattering index 3.33<$β$<3.62, and a mean flux density of 0.53-0.62 mJy at 1 GHz with a steep spectral index 2.06<$α$<2.35. Around 15% of the emission is linearly and circularly polarised, but the polarisation angle does not follow the rotating vector model. Thanks to the sensitivity of MeerKAT, we successfully measure a rate of periastron advance of 0.0171(11) deg/yr, and a Shapiro delay with an orthometric amplitude of 3.6$\pm$0.5 $μ$s and an orthometric shape of 0.85$\pm$0.05. The main source of uncertainty in our timing analysis is chromatic correlated dispersion measure noise, which we model as a power law in the Fourier space thanks to the large frequency coverage provided by the Parkes UWL receiver. Assuming general relativity and accounting for the measurements across all the implemented timing noise models, the total mass, companion mass, pulsar mass and inclination angle are constrained at 2.3

Calculation of eigenvalues of a strongly chaotic system using Gaussian wavepacket dynamics

Year: 1997

description: We apply the approximate dynamics derived from the Gaussian time-dependent variational principle to the Hamiltonian $ \hat H= {1/2}(\hat p_x ^2+ \hat p_y ^2)+ {1/2}\hat x^2\hat y^2$, which is strongly chaotic in the classical limit. We are able to calculate, essentially analytically, low-lying eigenvalues for this system. These approximate eigenvalues agree within a few percent with the numerical results. We believe that this is the first example of the use of TDVP dynamics to compute individual eigenvalues in a non-trivial system and one of the few such computations in a chaotic system by any method. There is a short self-contained discussion on the validity of Gaussian approximations in the paper.

Happiness and Superlative Value in the Eudemian Ethics

description: In my dissertation Happiness and Superlative Value in the Eudemian Ethics, I analyze dimensions of the Eudemian Ethics (EE) that, as I see it, make the EE a distinctive contribution to ethics. The EE discusses a superlative excellence called kalokagathia, the virtue of being-beautiful-and-good, which does not figure in the Nicomachean Ethics (NE). The agent who possesses kalokagathia is the best agent of Aristotle’s EE. Scholars tend to hold that the practically wise person, the phronimos, or the theoretically wise person, the sophos, are the best agents of the NE. If my reading of the EE is right, then the EE and the NE conceive differently of the best agent. This is salient in both treatises’ construals of the unity of the virtues. In the NE, the unity of the virtues includes the character virtues and phronêsis. In the EE, it additionally includes the virtues of theoretical thinking, or so I argue. The EE starts with what I call the Superlative Thesis (ST): happiness is what is best, most beautiful, and most pleasant of all. I take this beginning to be programmatic. Aristotle aims to show how these three kinds of value combine in the best human life, rather than coming apart. The Pleasure Thesis (PT) is the most contested aspect of ST: happiness is the most pleasant thing of all. On my reading, Aristotle fully embraces PT. In laying out his proposal for the best human life, the Aristotle of the EE develops a distinctive kind of naturalism, which I call Natural Goods Naturalism. I reconstruct this position in two steps: by interpreting the EE’s function argument; and by exploring the notion of natural goods, which is central to the EE, but does not figure in the NE. In sum, my dissertation argues that the EE contains a distinctive and under-appreciated option within ancient ethics, and that it contains ideas that are relevant to today’s virtue ethics and ethical naturalism.

description: The asymptotic wave speed for FKPP type reaction-diffusion equations on a class of infinite random metric trees are considered. We show that a travelling wavefront emerges, provided that the reaction rate is large enough. The wavefront travels at a speed that can be quantified via a variational formula involving the random branching degrees $\vec{d}$ and the random branch lengths $\vec{\ell}$ of the tree. This speed is slower than that of the same equation on the real line $\mathbb{R}$, and we estimate this slow down in terms of $\vec{d}$ and $\vec{\ell}$. Our key idea is to project the Brownian motion on the tree onto a one-dimensional axis along the direction of the wave propagation. The projected process is a multi-skewed Brownian motion, introduced by Ramirez [Multi-skewed Brownian motion and diffusion in layered media, Proc. Am. Math. Soc., Vol. 139, No. 10, pp.3739-3752, 2011], with skewness and interface sets that encode the metric structure $(\vec{d}, \vec{\ell})$ of the tree. Combined with analytic arguments based on the Feynman-Kac formula, this idea connects our analysis of the wavefront propagation to the large deviations principle (LDP) of the multi-skewed Brownian motion with random skewness and random interface set. Our LDP analysis involves delicate estimates for an infinite product of $2\times 2$ random matrices parametrized by $\vec{d}$ and $\vec{\ell}$ and for hitting times of a random walk in random environment. By exhausting all possible shapes of the LDP rate function (action functional), the analytic arguments that bridge the LDP and the wave propagation overcome the random drift effect due to multi-skewness.

description: Active solids, more specifically elastic lattices embedded with polar active units, exhibit collective actuation when the elasto-active feedback, generically present in such systems, exceeds some critical value. The dynamics then condensates on a small fraction of the vibrational modes, the selection of which obeys non trivial rules rooted in the nonlinear part of the dynamics. So far the complexity of the selection mechanism has limited the design of specific actuation. Here we investigate numerically how, localizing the activity on a fraction of modes, one can select non-trivial collective actuation. We perform numerical simulations of an agent based model on triangular and disordered lattices and vary the concentration and the localization of the active agents on the lattices nodes. Both contribute to the distribution of the elastic energy across the modes. We then introduce an algorithm, which, for a given fraction of active nodes, evolves the localization of the activity in such a way that the energy distribution on a few targeted modes is maximized -- or minimized. We illustrate on a specific targeted actuation, how the algorithm performs as compared to manually chosen localization of the activity. While, in the case of the ordered lattice, a well educated guess performs better than the algorithm, the latter outperform the manual trials in the case of the disordered lattice. Finally, the analysis of the results in the case of the ordered lattice leads us to introduce a design principle based on a measure of the susceptibility of the modes to be activated along certain activation paths.

description: We determine the spectrum of currents generated by the operator product expansion of the energy-momentum tensor in N=4 super-symmetric Yang-Mills theory. Up to the regular terms and in addition to the multiplet of the stress tensor, three current multiplets appear, Sigma, Xi and Upsilon, starting with spin 0, 2 and 4, respectively. The OPE's of these new currents generate an infinite tower of current multiplets, one for each even spin, which exhibit a universal structure, of length 4 in spin units, identified by a two-parameter rational family. Using higher spin techniques developed recently for conformal field theories, we compute the critical exponents of Sigma, Xi and Upsilon in the TT OPE and prove that the essential structure of the algebra holds at arbitrary coupling. We argue that the algebra closes in the strongly coupled large-$N_c$ limit. Our results determine the quantum conformal algebra of the theory and answer several questions that previously remained open.

description: Technological advances in the last decade have given rise to large Genome Wide Studies which have helped researchers get better insights in the genetic basis of many common diseases. As the number of samples and genome coverage has increased dramatically it is currently typical that individuals are genotyped using high throughput platforms to more than 500,000 Single Nucleotide Polymorphisms. At the same time theoretical and empirical arguments have been made for the use of haplotypes, i.e. combinations of alleles at multiple loci in individual chromosomes, as opposed to genotypes so the problem of haplotype inference is particularly relevant. Existing haplotyping methods include population based methods, methods for pooled DNA samples and methods for family and pedigree data. Furthermore, the vast amount of available data pose new challenges for haplotyping algorithms. Candidate methods should scale well to the size of the datasets as the number of loci and the number of individuals are well to the thousands. In addition, as genotyping can be performed routinely, researchers encounter a number of specific new scenarios, which can be seen as hybrid between the population and pedigree inference scenarios and require special care to incorporate the maximum amount of information. In this thesis we present a Sequential Monte Carlo framework (TDS) and tailor it to address instances of haplotype inference and frequency estimation problems. Specifically, we first adjust our framework to perform haplotype inference in trio families resulting in a methodology that demonstrates an excellent tradeoff between speed and accuracy. Consequently, we extend our method to handle general nuclear families and demonstrate the gain using our approach as opposed to alternative scenarios. We further address the problem of haplotype inference in pooling data in which we show that our method achieves improved performance over existing approaches in datasets with large number of markers. We finally present a framework to handle the haplotype inference problem in regions of CNV/SNP data. Using our approach we can phase datasets where the ploidy of an individual can vary along the region and each individual can have different breakpoints.

description: We construct a class of negative spin irreducible representations of the su(2) Lie algebra. These representations are infinite-dimensional and have an indefinite inner product. We analyze the decomposition of arbitrary products of positive and negative representations with the help of generalized characters and write down explicit reduction formulae for the products. From the characters, we define effective dimensions for the negative spin representations, find that they are fractional, and point out that the dimensions behave consistently under multiplication and decomposition of representations.

title: The Adoption of Western Management Accounting Practices in Vietnamese Enterprises During Economic Transition

description: Following Vietnam’s re-unification in 1975, accounting practices and systems throughout the country were similar to those adopted by the Soviet Union and China. Since the late 1980s, however, Vietnam has been in the process of transforming itself from a centrally planned economy to a market-oriented one, as a result of which the business environment has become much more competitive. The orientation of the accounting system has changed from one that served only the needs of state tax authorities to one that could also serve the needs of management. In turn, these changes have created a need for management accounting in Vietnamese enterprises. Despite such far-reaching changes, there is a lack of systematic knowledge about the current state of management accounting practices (MAPs) in Vietnam. This situation is consistent with a general lack of detailed information and understanding of MAPs in developing and/or transitional economies. This study seeks to help fill an important gap in the literature by investigating past and current MAPs in Vietnamese enterprises, factors that may have facilitated the adoption of western MAPs in such enterprises, and the costs and benefits of such adoption. In so doing, the study will add to management accounting literature by contributing supplementary information relating to an Asian perspective of MAPs. Data was collected using a multi-method approach including a questionnaire survey and interviews. Data for the study were collected from 220 accouting heads and vice heads of medium-to-large enterprises. Follow-up interviews were conducted with 20 accounting heads/vice heads to obtain further information and clarifications. The quantitative data collected was analyzed using both descriptive and inferential statistics (including t-tests, ANOVA, and structural equation modeling), while the qualitative data was used to shed further light on the various relationships described by the quantitative analysis.

description: Values for the vacuum energy of scalar fields under Dirichlet and Neuman boundary conditions on an infinite clylindrical surface are found, and they happen to be of opposite signs. In contrast with classical works, a complete zeta function regularization scheme is here applied. These fields are regarded as interesting both by themselves and as the key to describing the electromagnetic (e.m.) case. With their help, the figure for the e.m. Casimir effect in the presence of this surface, found by De Raad and Milton, is now confirmed.

description: The Myra Falls Minesite on Vancouver Island, British Columbia contains a relatively large waste rock pile built against a valley wall and having a lateral extent of 800 meters by 300 meters with a height of up to 40 meters. The waste rock dump has been generating acid for at least a decade. Acid-base accounting of 230 borehole samples has shown that the most active areas of oxidation occur within a 10 meter depth of exposed surfaces of the waste rock dump and in deeper zones where relatively high contents of sulfide minerals are located. Water moving through the waste rock dump originates from infiltration of precipitation and lateral groundwater discharge from the valley wall. During periods of significant rainfall, the shallow acid-generating zones are flushed with water and acidic water appears beneath the water table. During periods of negligible rainfall, neutral-pH water is present beneath the water table. However, general calculations suggest that a significant portion of the annual production of acidity is retained in the dump and therefore remains available for flushing. As a result, remediation and decommissioning planning must address the neutralization of this acidity or the control of infiltration and water-table variation. Various approaches to preventing acid mine drainage were evaluated. The most promising approach was the development of a cementitious solidification mixture incorporating mine waste materials for use as a waste rock dump surface sealant and grouting matrix. Mine waste water sludge and mine tailings were used as principal components of the solidification mixtures. A field assessment program was also carried out to evaluate the application and durability of the test mixtures on waste rock test piles. The solidified materials prepared have achieved similar properties to construction concrete in terms of compression strengths, setting times, workability and durability as measured by freeze/thaw testing. In addition, the solidification mixtures can be prepared at costs less than costs associated with other surface sealants such as high density polyethylene.

description: Robust optimization (RO) tackles data uncertainty by optimizing for the worst-case scenario of an uncertain parameter and, in its basic form, is sometimes criticized for producing overly-conservative solutions. To reduce the level of conservatism in RO, one can use the well-known budget-of-uncertainty approach which limits the amount of uncertainty to be considered in the model. In this paper, we study a class of problems with resource uncertainty and propose a robust optimization methodology that produces solutions that are even less conservative than the conventional budget-of-uncertainty approach. We propose a new tractable two-stage robust optimization approach that identifies the "ineffective" parts of the uncertainty set and optimizes for the "effective" worst-case scenario only. In the first stage, we identify the effective range of the uncertain parameter, and in the second stage, we provide a formulation that eliminates the unnecessary protection for the ineffective parts, and hence, produces less conservative solutions and provides intuitive insights on the trade-off between robustness and solution conservatism. We demonstrate the applicability of the proposed approach using a power dispatch optimization problem with wind uncertainty. We also provide examples of other application areas that would benefit from the proposed approach.

description: Motivated by recent experiments in fermionic polar gases, we study the non-equilibrium dynamics of two-component dipolar fermions subject to a quasiperiodic potential. We investigate the localization of charge and spin degrees of freedom time evolving with a long-range spin-SU(2) symmetric fermionic Hamiltonian, by calculating experimentally accessible dynamical observables. To study the non-equilibrium dynamics, we start the time evolution with two initial states at half-filling: (i) product state with doublons $|\uparrow \downarrow 0 \uparrow \downarrow 0 \uparrow \downarrow 0 \uparrow \downarrow 0 \uparrow \downarrow \rangle$ and (ii) product state with singlons $|\uparrow \ \downarrow \ \uparrow \ \downarrow \ \uparrow \ \downarrow \ \uparrow \ \downarrow \ \uparrow \ \downarrow \ \rangle$. We carried out the real-time evolution via the fermionic Hamiltonian using exact diagonalization(ED) and the time-dependent variational principle (TDVP) for finite Matrix product states(MPSs), within experimentally relevant time scales. For the product state with doublons, we observe a delocalized to localized phase transition varying disorder strengths, by monitoring the decay of charge imbalance with time. For the long-range interacting Hamiltonian of our focus, and in the presence of strong enough disorder, starting the time evolution with singlons we find a strong reduction in the spin delocalization, contrary to results of previous studies using the disordered short-range (on-site) Hubbard model with SU(2) symmetry. Our predictions for localization of both charge and spin should be observable in ultra-cold experiments with fermionic dipolar atoms subject to a quasiperiodic potential.

We use the method of symmetric space as well as the non-Abelian gauge technique to obtain the supersymmetric integrable hierarchies of the AKNS type from the zero curvature condition in superspace with the graded algebras, sl(n+1,n), providing the Hermitian symmetric space structure.

description: We derive formulae for the soft limit of tree-level gluon and graviton correlators in Anti-de Sitter space, which arise from Feynman diagrams encoding the Weinberg soft theorems in flat space. Other types of diagrams can also contribute to the soft limit at leading order in the soft momentum, but have a different pole structure. We derive these results at four points using explicit formulae recently obtained from the cosmological bootstrap and double copy, and extend them to any multiplicity using bootstrap techniques in Mellin-momentum space.

description: Object detection in complex scenes plays an important role in many real world applications, such as scene analysis, security, traffic violation detection, and medical research. The Object Detection and Behaviour Classification (ODBC) system created from this PhD research, is ground-breaking and concentrates solely on the domain of people and behaviour detection in low resolution beach scene imagery. The video source for this research was obtained from Coastalwatch beach webcams, which are located throughout Australia. Current object detection systems, overall, utilise a similar methodology, following four main image processing procedures; 1) remove unwanted noise, 2) background extraction from an image scene, 3) segmentation of the objects from the scene, and 4) object classification into different class types. To my knowledge, there is no other past or current research studying behaviour detection in low resolution beach imagery, and therefore, my research leads the way in this domain. Information from beach imagery can provide important data for tourism promotions and beach safety. Analysis of people behaviour could assist in making decisions about promotions and beach amenities. Automated beach systems may provide constant monitoring of a beach, by detecting people entering the ocean in a flagged or non-flagged area of a beach. This may also provide an early warning system to assist lifeguards in protecting swimmers in a beach area.
Spin-order dependent anomalous Hall effect and magneto-optical effect in noncollinear antiferromagnets Mn$_{3}X$N ($X$ = Ga, Zn, Ag, and Ni)

description: Noncollinear antiferromagnets (AFMs) have recently attracted a lot of attention owing to the potential emergence of exotic spin orders on geometrically frustrated lattices, which can be characterized by corresponding spin chiralities. By performing first-principles density functional calculations together with group-theory analysis and tight-binding modelling, here we systematically study the spin-order dependent anomalous Hall effect (AHE) and magneto-optical effect (MOE) in representative noncollinear AFMs Mn$_{3}X$N ($X$ = Ga, Zn, Ag, and Ni). The symmetry-related tensor shape of the intrinsic anomalous Hall conductivity (IAHC) for different spin orders is determined by analyzing the relevant magnetic point groups. We show that while only the ${xy}$ component of the IAHC tensor is nonzero for right-handed spin chirality, all other elements, $σ_{xy}$, $σ_{yz}$, and $σ_{zx}$, are nonvanishing for a state with left-handed spin chirality owing to lowering of the symmetry. Our tight-binding arguments reveal that the magnitude of IAHC relies on the details of the band structure and that $σ_{xy}$ is periodically modulated as the spin rotates in-plane. The IAHC obtained from first principles is found to be rather large, e.g., it amounts to 359 S/cm in Mn$_{3}$AgN. By extending our analysis to finite frequencies, we calculate the optical isotropy [$σ_{xx}(ω)\approxσ_{yy}(ω)\approxσ_{zz}(ω)$] and the magneto-optical anisotropy [$σ_{xy}(ω)\neqσ_{yz}(ω)\neqσ_{zx}(ω)$] of Mn$_{3}X$N. We argue that the spin-order dependent AHE and MOE are indispensable in detecting complex spin structures in noncollinear AFMs.
