(Fermionic)Mass Meets (Intrinsic)Curvature

Using the notion of vacuum pairs we show how the (square of the) mass matrix of the fermions can be considered geometrically as curvature. This curvature together with the curvature of space-time, defines the total curvature of the Clifford module bundle representing a ``free'' fermion within the geometrical setup of spontaneously broken Yang-Mills-Higgs gauge theories. The geometrical frame discussed here gives rise to a natural class of Lagrangian densities. It is shown that the geometry of the Clifford module bundle representing a free fermion is described by a canonical spectral invariant Lagrangian density.Comment: 14 page

A generalized Lichnerowicz formula, the Wodzicki Residue and Gravity

We prove a generalized version of the well-known Lichnerowicz formula for the square of the most general Dirac operator $\widetilde{D}$\ on an even-dimensional spin manifold associated to a metric connection $\widetilde{\nabla}$. We use this formula to compute the subleading term $\Phi_1(x,x, \widetilde{D}^2)$\ of the heat-kernel expansion of $\widetilde{D}^2$. The trace of this term plays a key-r\hat {\petit\rm o}le in the definition of a (euclidian) gravity action in the context of non-commutative geometry. We show that this gravity action can be interpreted as defining a modified euclidian Einstein-Cartan theory.Comment: 10 pages, plain te

Tenability in stairwell of highrise office buildings.

The commonly adopted fire evacuation strategy for office buildings is total evacuation which involves simultaneous evacuation of all building occupants upon fire alarm activation. Total evacuation for building with high occupancy load will cause congestion within stairwell which often results in long queuing time at the stairwell door. Long queuing time on the fire floor causes the stairwell door to remain open for extensive period, and the smoke from the fire floor will enter the stairwell resulting in untenable conditions within the stairwell. This can have devastating effects on egressing occupants. This research utilises the state-of-the-art modelling tools such as FDS and FDS+Evac to study high-rise office building with two means of escape. The aim was to demonstrate that for certain building parameters, phased evacuation should be adopted instead of total evacuation to ensure an acceptable tenability level within the stairwells which permits safe evacuation of the occupants. A total of 48 unique simulations were identified based on varying building parameters such as floor area, building height, fire protection system, evacuation strategy and ceiling height. Relevant New Zealand Building Code (NZBC) Compliance Documents such as C/AS5, C/VM2 and D1/AS1 were used as guidelines to define the various modelling parameters such as fire growth and combustion characteristics, fire safety systems, modelling rules, evacuation parameters and geometries to ensure the modelled building achieves the minimum NZBC requirements. The use of FDS+Evac for simulating evacuation timings without the effect of smoke was validated to some extent against hydraulic models and relevant trial evacuation experiments found in the literature. The results demonstrate that for high-rise office buildings up to 20 storeys with floor area not exceeding 510 m² served by either conventional or scissor stairwell, the tenability within the stairwell can be maintained during total evacuation by having at least a Type 6 automatic fire sprinkler system. For high-rise office buildings between 10 to 20 storeys with floor area of 5000 m² or 2450 m² served by either conventional or scissor stairwell, those buildings are required be protected by Type 7 automatic fire sprinkler system with smoke detection and phased evacuation are also required to maintain tenability within the stairwell. The effect of stair arrangement on the tenability in the stairwell is more evident in highrise office buildings with high occupancy load where scissor stairwell is found to be worse than conventional stairwell. This is due to the nature of scissor stair arrangement which forces smoke to flow up the stairwell in a corkscrew manner, concentrating smoke along a specific path. This phenomenon is found to be detrimental to the tenability conditions in the stairwell

Disseminated coccidioidomycosis: Monitoring of serologic markers for treatment response

We describe a patient with a disseminated coccidioidomycosis. Biomarkers in serum during itraconazole therapy showed a rapid clearing of Coccidioides DNA as detected by PCR. Coccidioides antibody detection by lateral flow assay became negative after one year and decreased from 1:64 to 1:8 in the complement fixation test after two years. The (1 → 3)-ß-D-glucan levels normalised after two years without increase after cessation of antifungal therapy. Biomarkers in serum may guide treatment decisions in disseminated coccidioidomycosis.Peer Reviewe

Z_2-Bi-Gradings, Majorana Modules and the Standard Model Action

The action functional of the Standard Model of particle physics is intimately related to a specific class of first order differential operators called Dirac operators of Pauli type ("Pauli-Dirac operators"). The aim of this article is to carefully analyze the geometrical structure of this class of Dirac operators on the basis of real Dirac operators of simple type. On the basis of simple type Dirac operators, it is shown how the Standard Model action (STM action) may be viewed as generalizing the Einstein-Hilbert action in a similar way the Einstein-Hilbert action is generalized by a cosmological constant. Furthermore, we demonstrate how the geometrical scheme presented allows to naturally incorporate also Majorana mass terms within the Standard Model. For reasons of consistency these Majorana mass terms are shown to dynamically contribute to the Einstein-Hilbert action by a "true" cosmological constant. Due to its specific form, this cosmological constant can be very small. Nonetheless, this cosmological constant may provide a significant contribution to dark matter/energy. In the geometrical description presented this possibility arises from a subtle interplay between Dirac and Majorana masses

Real world music object recognition

We present solutions to two of the most pressing issues in contemporary optical music recognition (OMR).We improve recognition accuracy on low-quality, real-world (i.e. containing ageing, lighting, or dirt artefacts among others) input data and provide confidence-rated model outputs to enable efficient human post-processing. Specifically, we present (i) a sophisticated input augmentation scheme that can reduce the gap between sanitised benchmarks and realistic tasks through a combination of synthetic data and noisy perturbations of real-world documents; (ii) an adversarial discriminative domain adaptation method that can be employed to improve the performance of OMR systems on low-quality data; (iii) a combination of model ensembles and prediction fusion, which generates trustworthy confidence ratings for each prediction. We evaluate our contributions on a newly created test set consisting of manually annotated pages of varying real-world quality, sourced from International Music Score Library Project (IMSLP) / the Petrucci Music Library. With the presented data augmentation scheme, we achieve a doubling in detection performance from 36.0% to 73.3% on noisy real-world data compared to state-of-the-art training. This result is then combined with robust confidence ratings paving the way forOMR to be deployed in the realworld. Additionally, we showthe merits of unsupervised adversarial domain adaptation for OMR raising the 36.0% baseline to 48.9%.
