The mean conformation tensor in viscoelastic turbulence

Year: 2019

subject: FOS: Physical sciences

description: This work demonstrates that the popular arithmetic mean conformation tensor frequently used in the analysis of turbulent viscoelastic flows is not a good representative of the ensemble. Alternative means based on recent developments in the literature are proposed, namely, the geometric and log-Euclidean means. These means are mathematically consistent with the Riemannian structure of the manifold of positive-definite tensors, on which the conformation tensor lives, and have useful properties that make them attractive alternatives to the arithmetic mean. Using a turbulent FENE-P channel flow dataset, it is shown that these two alternatives are physically representative of the ensemble. By definition these means minimize the geodesic distance to realizations and exactly preserve the scalar geometric mean of the volume and of the principal stretches. The proposed geometric and log-Euclidean means have a clear physical interpretation and provide an attractive quantity for turbulence modelling.

Tautomerism

description: Two different tautomeric forms may be written for monoaza-heterocyclic mereapto-compounds, one with the mobile hydrogen atom on sulphur and the other with the mobile hydrogen on nitrogen. For example 4-mercaptopyridine may exist in the tautomeric forms: (l; R = K) or' (II; R = H).Additional NH forms are possible for polyazaheterocyclic mereapto-compounds. The tautomerism of the mercapto-derivatives of six-membered rings has been little examined. Isolated qualitative studies of the tautomerism have been undertaken but no quantitative approach to the problem has previously been attempted. The present investigation was undertaken with the aim of elucidating the structure of simple nitrogenous heterocyclic mereapto-compounds in water because of their relationship to the biologically important 2-thiouracil derivatives which may be represented as (h i ). In the present work the mercapto - compounds have been studied by reference to fixed tautomeric forms in which the mobile hydrogen atom was replaced by an immobile methyl - group e.g. (I and II; R = Me). This can be done because changes in ultraviolet absorption spectra and ionization constants are small upon W- or Smethylation. Finally, by employing ionization constants, the ratio of the tautomers at equilibrium in rnonoaza - heterocyclic mercapto - compounds was calculated.

description: The combined effect of nonmagnetic and magnetic defects and impurities on critical temperatures of superconductors with different gap anisotropy is studied theoretically within the weak coupling limit of the BCS model. An expression is derived which relates the critical temperature to relaxation rates of charge carriers by nonmagnetic and magnetic scatterers, as well as to the coefficient of anisotropy of the superconducting order parameter on the Fermi surface. Particular cases of d-wave, (s+d)-wave, and anisotropic s-wave superconductors are briefly discussed.

description: ABSTRACT

Background: Workplace violence has emerged as a global problem that affects all nations, workplaces, and occupational categories. The health sector accounts for more than one-third of all workplace violence worldwide. There is very little information available in Ethiopia about workplace violence affecting healthcare professionals. This study aims to shed light on the issue by gaining a better understanding of the problem and developing a targeted intervention. Therefore, the objective of the study was to assess the prevalence of workplace violence and associated factors among healthcare professionals working in selected public hospitals in Addis Ababa, Ethiopia.

Methods: An analytic cross-sectional study was conducted from May 1- June 30, 2023 among 599 randomly selected healthcare professionals working at four randomly selected referral hospitals in Addis Ababa, Ethiopia. Data was collected using a pretested structured self-administered questionnaire adapted from the  ILO/ICN/WHO/PSI a. The data were coded and entered to EPI information version 7 and exported to SPSS V.20.0 software for analysis. Frequency table was used to summarize data. To identify factors associated with workplace violence, a binary logistic regression model where the degree of association for variables was assessed using adjusted odds ratios (AOR) with 95% CI and p-value ≤0.05.

Result:  The prevalence of experiencing at least one type of workplace violence (physical, verbal, bullying, or sexual) in the previous year was found to be 59.4% (95% CI = 55.6–63.1). The study revealed a statistically significant relationship between workplace violence and female sex (AOR=1.56, 95% CI=1.04-2.34, p=0.033), pharmacist profession (AOR=2.9, 95% CI=1.15-7.33, p=0.025), routine direct physical contact with patients (AOR=2.19, 95% CI=1.12-4.29, p=0.022), emergency work starting (AOR=2.50, 95% CI=1.02-6.15, p=0.045), and witnessing incidents of physical violence (AOR=10.1, 95% CI=5.75-17.59, p<0.0001). 

Conclusion: The study found a high prevalence of workplace violence among health care professionals working in government hospitals in Addis Ababa, Ethiopia. Healthcare facilities should prioritize the establishment of comprehensive health and safety programs focusing on the prevention and management of workplace violence, with particular attention to the most vulnerable groups.

description: We describe a maximum-likelihood technique for the removal of contaminating radio sources from interferometric observations of the Sunyaev-Zel'dovich (SZ) effect. This technique, based on a simultaneous fit for the radio sources and extended SZ emission, is also compared to techniques previously applied to Ryle Telescope observations and is found to be robust. The technique is then applied to new observations of the cluster Abell 611, and a decrement of -540 +/- 125 microJy/beam is found. This is combined with a ROSAT HRI image and a published ASCA temperature to give an Hubble constant estimate of 52+24-16 km/s/Mpc.

description: Galactic cosmic rays undergo complex nuclear interactions with nuclei within planetary bodies that have little to no atmosphere. Radiation transport simulations are a key tool used in understanding the neutron and gamma-ray albedo coming from these interactions and tracing these signals back to geochemical composition of the target. We study the validity of the code Geant4 for simulating such interactions by comparing simulation results to data from the Apollo 17 Lunar Neutron Probe Experiment. Different assumptions regarding the physics are explored to demonstrate how these impact the Geant4 simulation results. In general, all of the Geant4 results over-predict the data, however, certain physics lists perform better than others. In addition, we show that results from the radiation transport code MCNP6 are similar to those obtained using Geant4.
The glass transition in a model silica glass: evolution of the local structure

description: We use molecular dynamics simulations and the Voronoi tessellation to study the geometrical modifications as a function of temperature in a model silica glass. The standard deviation of the cell volumes, which is a measure of the local density fluctuations, decreases with decreasing temperature, as if it would like to vanish at zero temperature. This evolution towards an ordered state is frozen out at the glass transition and consequently an amorphous sample is obtained at low temperature. This structural freezing following upon the glass transition is noticeable in all the other geometric characteristics of the Voronoi cells and a possible interpretation in terms of geometrical frustration is proposed.

description: The Kepler Space Telescope has discovered thousands of planets via the transit method. The transit timing variations of these planets allows us not only to infer the existence of other planets, transiting or not, but to characterize a number of parameters of the system. Using the transit timing variations of the planets Kepler-159b and 159c, the transit simulator TTVFast, and the Bayesian Inference tool MultiNest, we predict a new non-transiting planet, Kepler-159d, in a resonant 2:1 orbit with Kepler-159c. This configuration is dynamically stable on at least 10 Myr time scales, though we note that other less stable, higher-order resonances could also produce similar TTVs during the three-year window Kepler was in operation.

description: Two-leg t-J ladders are investigated in the framework of a combination of the phase string formulation and bond-operator representation. We develope a mean-field theory in the strong rung interaction regime, i.e. $J_{\perp}\gg J, t$, which provides a unified description of the undoped insulating phase and the low doping phase --- the so-called C1S0 phase. Both of them are characterized by the resonating-valence-bond (RVB) order parameter, with gap opened up in all spin excitations. The ground state of the doped phase is intrinsically a superconductor with a d-wave symmetry, which is driven by the RVB correlations. The ground-state energy is in good agreement with numerical results. Phase separation is shown to occur beyond some critical value of J/t for given doping concentration. We also show that the spin gap in the doped phase is determined by quasi-particle-like excitations. The local structure of hole pairs as well as the spectra of various spin and charge modes are analyzed in comparison with other approaches.

description: We obtain a ``mean field'' scaling flow of the longitudinal and the Hall conductivities in the fractional quantum Hall regime. Using the composite fermion picture and assuming that the composite fermions follow the Khmelnitskii-Pruisken scaling flow for the integer quantum Hall effect, the unstable fixed points which govern the transitions between different fractional quantum Hall states are identified. Distributions of the critical longitudinal and Hall conductivities at the unstable fixed points are obtained and implications of the results for the experiments on mesoscopic quantum Hall systems are discussed.

photodisintegration

description: The experimental results pertaining to nuclear photdisintegration and the giant resonance are summarised, It is pointed out that although most of the observed nucleon emission is characteristic of a decaying compound nucleus, there generally remains a component which is presumed to arise from direct interactions, The principal theoretical models proposed to account for the absorption are briefly discussed; the relationship between the collective and independent particle model descriptions is indicated, and it is shown that the latter formulation is able to account for the propertied of the direct component as far as they are known. The points at which some of the experiments described in later chapters provide additional information about direct emission and test the predictions of the single particle theory are indicated.
X-ray spectra of accretion discs with dynamic coronae

description: We compute the X-ray spectra produced by non-static coronae atop accretion discs around black holes and neutron stars. The hot corona is radiatively coupled to the underlying disc (the reflector) and generates an X-ray spectrum which is sensitive to the bulk velocity of the coronal plasma, beta=v/c. We show that an outflowing corona reproduces the hard-state spectrum of Cyg X-1 and similar objects. The dynamic model predicts a correlation between the observed amplitude of reflection R and the X-ray spectrum slope Gamma since both strongly depend on beta. A similar correlation was observed and its shape is well fitted by the dynamic model. The scattering of soft radiation in an outflowing corona can also account for the observed optical-UV polarization pattern in active galactic nuclei.

description: In the interstellar medium, carbon (nano-)grains are a major component of interstellar dust. This solid phase is more vulnerable to processing and destruction than its silicate counterpart. It exhibits a complex, size-dependent evolution due to interactions within different radiative and dynamical environments. Infrared signatures of these nanocarbon grains are seen in a large number of disks around Herbig HAeBe stars. We probe the composition and evolution of carbon nano-grains at the surface of (pre-)transitional protoplanetary disks around Herbig stars. We present spatially resolved infrared emission spectra obtained with NAOS CONICA at the VLT in the 3-4 $μ$m range with a spatial resolution of 0.1", which allow us to trace aromatic, olefinic and aliphatic bands which are attributed to sub-nanometer hydrocarbon grains. We apply a gaussian fitting to analyse the observed spectral signatures. Finally, we propose an interpretation in the framework of the The Heterogeneous dust Evolution Model of Interstellar Solids (THEMIS). We show the presence of several spatially extended spectral features, related to aromatic and aliphatic hydrocarbon material in disks around Herbig stars, from ~ 10 to 50-100 au, and even in inner gaps devoided of large grains. The correlation and constant intensity ratios between aliphatic and aromatic CH stretching bands suggest a common nature of the carriers. Given their expected high destruction rates due to UV photons, our observations suggest that they are continuously replenished at the disk surfaces.

description: In this thesis, a framework for real time control (RTC) of stormwater biofilters is developed, to eliminate the risks posed by faecal microbes in stormwater harvesting and reuse. By integrating modelling and laboratory experiments, a model was developed for microbial removal in biofilters, and it was modified and validated for RTC evaluation and selection. Two RTC strategies were developed and tested through laboratory experiments, and two additional strategies were conceptualised and assessed in modelling scenarios. This study presents the first stepping stone toward RTC of stormwater biofilters, demonstrating that RTC can help to deliver safe water for harvesting and reuse.

description: This thesis deals with two completely separate topics. The first section is concerned with the performance and interpretation of two double scattering experiments, while the second describes an experimental study of the Li7(y,p) activation curve. The investigation of polarization in (d,p) reactions at low energies was suggested by Dr. P.B. Treacy and carried out by us jointly including design of apparatus, taking of data and analysis of results, The analysis presented here is my own and differs in detail from that published by us earlier. The experiments of chapter four followed naturally from the polarization experiments, The results were taken largely by Mr. G. D. Symons and myself. it was found that the analysis of the data in terms of the interference of coulomb and resonance scattering required the adaptation of an existing formulation of polarization theory. This was carried through by myself. (First three paragraphs of Preface.)

description: We have studied the superconducting behavior of 100 nm Titanium Nitride (TiN) thin film in a perpendicular magnetic field. We found a zero field transition temperature of 4.6 K and a slope in the H-T plane of -0.745 T/K. At 4.2 K, we have performed careful transport measurements by measuring both the differential resistivity and voltage as a function of a DC current. Our results are analyzed in the framework of linear and non linear flux flow behavior. In particular, we have observed an electronic instability at high vortex velocities and from its dependence with respect to the applied magnetic field, we can exctract the inelastic scattering time and diffusion length of the quasiparticles.

description: The paper is devoted to the study of fine properties of the first eigenvalue on negatively curved spaces. First, depending on the parity of the space dimension, we provide asymptotically sharp harmonic-type expansions of the first eigenvalue for large geodesic balls in the model $n$-dimensional hyperbolic space, complementing the results of Borisov and Freitas (\textit{Comm. Anal. Geom.} 25: 507--544, 2017). We then give a synthetic proof of Cheng's sharp eigenvalue comparison theorem in metric measure spaces satisfying a 'negatively curved' Bishop-Gromov-type volume monotonicity hypothesis. As a byproduct, we provide an example of simply connected, non-compact Finsler manifold with constant negative flag curvature whose first eigenvalue is zero; this result is in a sharp contrast with its celebrated Riemannian counterpart due to McKean (\textit{J. Differential Geom.} 4: 359--366, 1970). Our proofs are based on specific properties of the Gaussian hypergeometric function combined with intrinsic aspects of the negatively curved smooth/non-smooth spaces.

description: Using molecular dynamics calculations and the Voronoi tessellation, we study the evolution of the local structure of a soft-sphere glass versus temperature starting from the liquid phase at different quenching rates. This study is done for different sizes and for two different boundary conditions namely the usual cubic periodic boundary conditions and the isotropic hyperspherical boundary conditions for which the particles evolve on the surface of a hypersphere in four dimensions. Our results show that for small system sizes, crystallization can indeed be induced by the cubic boundary conditions. On the other hand we show that finite size effects are more pronounced on the hypersphere and that crystallization is artificially inhibited even for large system sizes.

Leadership in the Liberal Party: Bolte, Askin and the Post-War Ascendancy

description: The formation of the Liberal Party of Australia in the mid-1940s heralded a new effort to stem the tide of government regulation that had grown with Labor Party rule in the latter years of World War II and immediately after. It was not until 1949 that the party gained office at Federal level, beginning what was to be a record unbroken term of 23 years, but its efforts faltered at State level in Victoria, where the party was divided, and in New South Wales, where Labor was seemingly entrenched. The fortunes were reversed with the rise to leadership of men who bore a different stamp to their predecessors, and were in many ways atypical Liberals: Henry Bolte in Victoria and Robin Askin in New South Wales. Bolte, a farmer, and Askin, a bank officer, had served as non-commissioned officers in World War II and rose to lead parties whose members who had served in the war were predominantly of the officer class. In each case, their man management skills put an end to division and destabilisation in their parties, and they went on to serve record terms as Liberal leaders in their respective States, Bolte 1955-72 and Askin 1965-75. Neither was ever challenged in their leadership and each chose the time and nature of his departure from politics, a rarity among Australian political leaders. Their careers are traced here in the context of the Liberal revival and the heightened expectations of the post-war years when the Liberal Party reached an ascendancy, governing for a brief time in 1969-70 in all Australian States as well as the Commonwealth. Their leadership is also examined in the broader context of leadership in the Liberal Party, and also in the ways in which the new party sought to engage with and appeal to a wider range of voters than had traditionally been attracted to the non-Labor parties.
Inhomogeneous metal enrichment at z \sim 1.9: the Lyman limit systems in the spectrum of the HDF-S quasar

description: We present a detailed analysis of three metal absorption systems observed in the spectrum of the HDF-South quasar J2233-606 (z_em = 2.238), taking advantage of new VLT-UVES high resolution data (R=45000, S/N = 40-60, λλ3050-10000 Å). Three main components, spanning about 300 km/s, can be individuated in the Lyman limit system at z~1.92. They show a surprisingly large variation in metallicities, respectively ~1/500, 1/8 and 1/100 solar. The large value found for the second component at z=1.9259, suggests that the line of sight crosses a star-forming region. In addition, there is a definite correlation between velocity position and ionisation state in this component, which we interpret as a possible signature of an expanding H II region. The systems at z~1.94 and z~1.87 have also high metallicity, ~1/4 and 1/3 solar. We find that photoionisation and collisional ionisation are equal alternatives to explain the high excitation phase revealed by O VI absorption, seen in these two systems. From the width of the Si IV, C IV, Si III and C III lines in the system at z~1.87, we can estimate the temperature of the gas to be log T ~ 4.7, excluding collisional ionisation. Finally, we compute the Si IV/C IV ratio for all Voigt profile components in a sample of log N(C IV) > 14 systems at z < 2. The values show a dispersion of more than an order of magnitude and most of them are much larger than what is observed for weaker systems. This is probably an indication that high column density systems preferably originate in galactic halos and are mostly influenced by local ionising sources.

description: This practice-led research investigates ways in which representations of Australian flora on ceramic vessels can communicate ideas about current environmental culture. The project developed from a curiosity about whether changing attitudes to Australia's environment, from colonisation to the present time of unprecedented species decline, might be found reflected on historical and contemporary ceramic objects. Botanical exploration and the scientific study of Australia's vast flora have produced a rich resource of natural history documentation. The aim was to establish a framework specific to the project that utilises these resources and current theoretical and practical approaches to understanding flora and the environment in both the sciences and humanities. Through this interdisciplinary enquiry, visual arts and botanical research methodologies intersected in the studio informing material, technical and conceptual developments. This exploration takes the form of an installation of wheel thrown vessels with carved and inlaid surface imagery of Australian flora, where, through form, imagery, material and placement, a metaphorical space is made in which to reflect on current environmental culture.

description: We study the forces that act on a point flux carrying an integral number of flux units in quantum Hall fluids. Forces due to external fields, Lorentz and Magnus type forces, and the forces due to mutual interaction of point fluxes are considered. The forces are related to the adiabatic curvature associated with families of Landau Hamiltonians. The problem displays distinct features of the quantum Hall fluids with point fluxes on the plane and on the torus, which, however, agree at the thermodynamic limit.

description: This thesis explores histories, remembrances and sentiments inscribed in music and dance of the Ogasawara Islands. Through a musical ethnography, the thesis illustrates the identity and dignity of this small, remote but extensively connected community in the Pacific. Since the first settlement of 1830, the islanders have suffered various hardships caused by colonialism, war and international politics. As a result, a fracturing of memories has occurred that created a deep sorrow in the islanders’ sentiments. However they hardly stand idle lamenting loss and absence while trying to console their sentiments through singing and dancing. The want of memories reveals a responsive sense of yearning, and calls for multiple forms of historical narratives, practices and performances. Music and dance can be vital media to recollect and retrieve things past, because they preserve various fragments of the past in song lyrics, bodily movements and dance choreographies. These fragmented memories are often judged as ambiguous, incomplete and defective in conventional historiography. A diversity of Ogasawara musical activities appears to represent the fracturing of memories, but it actually provides an alternative view to see the islands beyond mere historical factuality, and enriches our historical consciousness, understandings and experiences towards collective remembrance. In this view from the frontier, the thesis recognises Ogasawara’s own memories that are associated with many other places and peoples, and affirms its identity and dignity beyond imagined boundaries of border, nation and ethnicity.
Is a Trapped One-Dimensional Bose Gas a Luttinger Liquid?

description: The low-energy fluctuations of a trapped, interacting quasi one-dimensional Bose gas are studied. Our considerations apply to experiments with highly anisotropic traps. We show that under suitable experimental conditions the system can be described as a Luttinger liquid. This implies that the correlation function of the bosons decays algebraically preventing Bose-Einstein condensation. At significantly lower temperatures a finite size gap destroys the Luttinger liquid picture and Bose-Einstein condensation is again possible.

Racialized Organization Theory

description: The purpose of this study is twofold. First, the general purpose is to examine the lack of Latina/o/x public school teachers in the Austin Independent School District (AISD). Second, identify and examine the individual, school, and organizational factors that create barriers to retaining Latinx maestra/o/x. In this research study, Racialized Organization Theory (ROT) is used to examine the colonial matrix of power at work within the schooling system in the U.S. as it pertains to the systematic exclusion of Latinx teachers. Utilizing qualitative methods, this research case study includes plàticas from Latinx public school teachers to gain insight into how they can be retained and sustained. Other sources of data include documentation analysis, journal writing, and memoing. Findings have implications for school leaders and policymakers who seek to improve teacher retention for Latinx teachers in urban public schools throughout the U.S.
Social Movements and the Limits of Strategy: How Australian Feminists Formed Positions on Work and Care

description: Feminism is often blamed for having made the 'wrong decisions' on issues such as work and care. This thesis argues that such judgements are based on a misperception of how social movements exercise collective agency. While feminist historiography and social movement studies offer some insights, neither directly address the question of to what extent the directions taken by social movements can be shaped by high level strategic decision-making. In answering this question, the research was informed by philosophical pragmatism and by feminist theories of responsibility and reason. The prevailing 'movement CEO' image of decision-making was rejected in favour of an approach directed to interpreting the past actions of the women’s movement without neglecting its decentralised and collective nature. ¶ ...

description: We determine the first through fourth moments of the order parameter, and various ratios, for several one- and two-dimensional models with absorbing-state phase transitions. We perform a detailed analysis of the system-size dependence of these ratios, and confirm that they are indeed universal for three models - the contact process, the A model, and the pair contact process - belonging to the directed percolation universality class. Our studies also yield a refined estimate for the critical point of the pair contact process.

description: Even moderate amounts of zero returns in financial data, associated with stale prices, are heavily detrimental for reliable jump inference. We harness staleness-robust estimators to reappraise the statistical features of jumps in financial markets. We find that jumps are much less frequent and much less contributing to price variation than what found by the empirical literature so far. In particular, the empirical finding that volatility is driven by a pure jump process is actually shown to be an artifact due to staleness.
Generalization of Wolf Effect of light on Arbitrary Two-Dimensional Surface of Revolution

description: Investigation of physics on two-dimensional curved surface has significant meaning in study of general relativity, inasmuch as its realizability in experimental analogy and verification of faint gravitational effects in laboratory. Several phenomena about dynamics of particles and electromagnetic waves have been explored on curved surfaces. Here we consider Wolf effect, a phenomenon of spectral shift due to the fluctuating nature of light fields, on an arbitrary surface of revolution (SOR). The general expression of the propagation of partially coherent beams propagating on arbitrary SOR is derived and the corresponding evolution of light spectrum is also obtained. We investigate the extra influence of surface topology on spectral shift by defining two quantities, effective propagation distance and effective transverse distance, and compare them with longitudinal and transverse proper lengths. Spectral shift is accelerated when the defined effective quantities are greater than real proper lengths, and vice versa. We also employ some typical SORs, cylindrical surfaces, conical surfaces, SORs generated by power function and periodic peanut-shell shapes, as examples to provide concrete analyses. This work generalizes the research of Wolf effect to arbitrary SORs, and provides a universal method for analyzing properties of propagation compared with that in flat space for any SOR whose topology is known.

description: Tracy and Dwyer (1969) introduced a matrix that was later given the name 'permuted idertity matrix' by MacRae (1974). She defined it to be an (mn,mn) matrix partitioned into m by n .th th submatrices such that the i] submatrik has a 1 in its ji position and zeroes elsewhere. She showed that this matrix could be used for reversing the order of a Kronecker product, a property very useful in the calculation of matrix derivatives. In this paper it will therefore be called 'commutation matrix'. This commutation matrix will be applied to some problems in statistics. Expressions will be derived for the expectations and covariance matrices of stochastic vectors x 0 y, where x N n (p 1 ,V 1 ) and y N 2' V,) are stochastically dependent; m .! x 0 x, where x Nn(11,V). These results wi.4.1 then be applied to the central and noncentral Wishart distributions for which the variance matrices will be der:7ved. Various related results will also be reported.

description: Gate-tunable semiconductor-superconductor nanowires with superconducting leads form exotic Josephson junctions that are a highly desirable platform for two types of qubits: those with topological superconductivity (Majorana qubits) and those based on tunable anharmonicity (gatemon qubits). Controlling their behavior, however, requires understanding their electrostatic environment and electronic structure. Here we study gated InAs nanowires with epitaxial aluminum shells. By measuring current-phase relations (CPR) and comparing them with analytical and numerical calculations, we show that we can tune the number of modes, determine the transparency of each mode, and tune into regimes in which electron-electron interactions are apparent, indicating the presence of a quantum dot. To take into account electrostatic and geometrical effects, we perform microscopic self-consistent Schrodinger-Poisson numerical simulations, revealing the energy spectrum of Andreev states in the junction as well as their spatial distribution. Our work systematically demonstrates the effect of device geometry, gate voltage and phase bias on mode behavior, providing new insights into ongoing experimental efforts and predictive device design.

description: We define $(p,q)$ hermitian geometry as the target space geometry of the two dimensional $(p,q)$ supersymmetric sigma model. This includes generalised Kähler geometry for $(2,2)$, generalised hyperkähler geometry for $(4,2)$, strong Kähler with torsion geometry for $(2,1)$ and strong hyperkähler with torsion geometry for $(4,1)$. We provide a generalised complex geometry formulation of hermitian geometry, generalising Gualtieri's formulation of the $(2,2)$ case. Our formulation involves a chiral version of generalised complex structure and we provide explicit formulae for the map to generalised geometry.
