Solving Linear Inverse Problems Provably via Posterior Sampling with Latent Diffusion Models (2023)

We present the first framework to solve linear inverse problems leveraging pre-trained latent diffusion models. Previously proposed algorithms (such as DPS and DDRM) only apply to pixel-space diffusion models. We theoretically analyze our algorithm showing provable sample recovery in a linear model setting. The algorithmic insight obtained from our analysis extends to more general settings often considered in practice. Experimentally, we outperform previously proposed posterior sampling algorithms in a wide variety of problems including random inpainting, block inpainting, denoising, deblurring, destriping, and super-resolution.
Shooting and bouncing rays: calculating the RCS of an arbitrarily shaped cavity (1989)

A ray-shooting approach is presented for calculating the interior radar cross section (RCS) from a partially open cavity. In the problem considered, a dense grid of rays is launched into the cavity through the opening. The rays bounce from the cavity walls based on the laws of geometrical optics and eventually exit the cavity via the aperture. The ray-bouncing method is based on tracking a large number of rays launched into the cavity through the opening and determining the geometrical optics field associated with each ray by taking into consideration: (1) the geometrical divergence factor, (2) polarization, and (3) material loading of the cavity walls. A physical optics scheme is then applied to compute the backscattered field from the exit rays. This method is so simple in concept that there is virtually no restriction on the shape or material loading of the cavity. Numerical results obtained by this method are compared with those for the modal analysis for a circular cylinder terminated by a PEC plate. RCS results for an S-bend circular cylinder generated on the Cray X-MP supercomputer show significant RCS reduction. Some of the limitations and possible extensions of this technique are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Quantitative Error Assessment in Pattern Matching: Effects of Intensity Pattern Noise, Interpolation, Strain and Image Contrast on Motion Measurements (2009)

Abstract: Basic concepts in probability are employed to develop analytic formulae for both the expectation (bias) and variance for image motions obtained during subset‐based pattern matching. Specifically, the expectation and variance in image motions in the presence of uncorrelated Gaussian intensity noise for each pixel location are obtained by optimising a least squares intensity matching metric. Results for both 1D and 2D image analyses clearly quantify both the bias and the covariance matrix for image motion estimates as a function of: (a) interpolation method, (b) sub‐pixel motion, (c) intensity noise, (d) contrast, (e) level of uniaxial normal strain and (f) subset size. For 1D translations, excellent agreement is demonstrated between simulations, theoretical predictions and experimental measurements. The level of agreement confirms that the analytical formulae can be used to provide a priori estimates for the ‘quality’ of local, subset‐based measurements achievable with a given pattern. For 1D strain with linear interpolation, theoretical predictions are provided for the expectation and co‐variance matrix for the local displacement and strain parameters. For 2D translations with bi‐linear interpolation, theoretical predictions are provided for both the expectation and the co‐variance matrix for both displacement components. Theoretical results in both cases show that the expectations for the local parameters are biased and a function of: (a) the interpolation difference between the translated and reference images, (b) magnitude of white noise, (c) decimal part of the motion and (d) intensity pattern gradients. For 1D strain, the biases and the covariance matrix for both parameters are directly affected by the strain parameter p 1 as the deformed image is stretched by (1 + p 1 ). For 2D rigid body motion case, the covariance matrix for measured motions is shown to have coupling between the motions, demonstrating that the directions of maximum and minimum variability do not generally coincide with the x and y directions.

Intelligent Mobile Robot Navigation in an Uncertain Dynamic Environment (2013)

This paper presents a modified sensor-based online method for mobile robot navigation generating paths in dynamic environments. The core of the navigation algorithm is based on the velocity obstacle avoidance method and the guidance-based tracking algorithm. A fuzzy decision maker is designed to combine the two mentioned algorithms intelligently. Hence the robot will be able to decide intelligently in various situations when facing the moving obstacles and moving target. A noble noise cancellation algorithm using Neural Network is designed to navigate the robot in an uncertain dynamic environment safely. The results show that the robot can track a moving target while maneuvering safely in dynamic environment and avoids stationary and moving obstacles.
Screw-type dislocations due to lattice mismatch in GaP: N/GaP epitaxy (1975)

Abstract Screw-type dislocation arrays were observed in GaP homogeneous epitaxy in which a nitrogen-doped GaP layer was grown on a pulled GaP substrate by the liquid-phase epitaxial method. Observations were carried out by X-ray transmission topography using a Lang camera. The lattice mismatch in this case originated from the doped nitrogen. Screw-type dislocations are favoured as misfit dislocations when a twist occurs about the normal to the interface. It is also shown that the misfit dislocation type depends on the ratio of δ/θ where δ and θ are Δd/d and the twist angle, respectively. From these considerations, it is demonstrated that it is reasonable that screw and 60° dislocations be formed at the interface at δ/θ ≪ 1 and = √3, respectively. Moreover, it is found that the interfacial energy may be expressed as E = E 0θ’ (A – ln θ') regardless of the type of the misfit dislocation.
Enhancing Blind Interference Alignment with Reinforcement Learning (2016)

Blind interference alignment (IA) is a signaling scheme that suppresses interference in multi-user systems, without the knowledge of channel state information at the transmitter (CSIT). The key to performing IA without CSIT is the use of reconfigurable antennas (RA) that are capable of dynamically switching among a fixed number of radiation patterns to introduce artificial fluctuations in the channel. The radiation patterns used to realize blind IA have significant impacts on the overall performance of the system. Hence, an intelligent antenna pattern selection strategy is a crucial component of any practical RA-based blind IA implementation. In this work, we propose two reinforcement learning algorithms for selecting the optimal antenna configuration for blind IA. Furthermore, we evaluate the performance of these antenna mode selection techniques using over the air measurements on our software defined radio implementation of blind IA using a Reconfigurable Alford Loop Antenna that is capable of generating multiple radiation patterns. We quantify the performance of the algorithms in terms of received signal to interference and noise ratio (SINR) and show that our learning-based mode selection strategies are capable of choosing the highest performing mode 90% of the time and attain over 2 dB gain in SINR over other selection approaches.
Can We Dispense With Space-Time? (1984)

According to the relational theory of space-time, the physical world contains spatio-temporal aggregates of matter (spatio-temporally extended physical objects, spatio-temporal parts’ of such objects, and aggregates consisting of spatio-temporal parts of different objects); these aggregates of matter are interrelated in various ways by various geometric (and also non-geometric) relations, but the physical world does not contain a space-time over and above these aggregates of matter and their interrelations. It is tempting to put this doctrine by saying that there are no space-time regions, but only aggregates of matter. This formulation might be faulted, for a relationalist might want to “logically construct” regions out of aggregates of matter, and given such a “logical construction” the relationalist will assert that regions do exist.
MEMS Reliability Assessment Methodology for Aerospace Applications (2006)

This paper presents a new dynamic and parametric model of a capacitive micro-electromechanical switch electro-statically actuated. It is built of elementary electrical equivalent-circuit blocks constructed of voltage controlled current sources. The model describes the nonlinear mechanical behaviour of the membrane movement, which allows the computation of the bridge capacitance. It can be inserted as a model to perform simulations as parasitic effects on MEMS structures. All switch parameters such as dimensions and material properties are adjustable.

1-GHz Monolithically Integrated Hybrid Mode-Locked InP Laser (2010)

This letter demonstrates a 1-GHz hybrid mode-locked monolithic semiconductor laser fabricated on indium phosphide. Its operating regimes are explored and optical pulses as short as 36 ps were measured. The linear cavity is 41 mm long with integrated active quantum well and passive waveguide structures. To our knowledge, this is the lowest reported repetition rate for a monolithically integrated mode-locked semiconductor laser. We further describe optimization steps of the saturable absorber reverse bias, driving RF frequency, and the semiconductor optical amplifier gain current for minimal output pulsewidth.

A longitudinal study of interleukin‐1 gene polymorphisms and periodontal disease in a general adult population (2001)

Abstract Background: Cross‐sectional studies have demonstrated that a specific polymorphism (allele 2 of both IL‐1A +4845 and IL‐1B +3954) in the IL‐1 gene cluster has been associated with an increased susceptibility to severe periodontal disease and to an increased bleeding tendency during periodontal maintenance. The aim of the present study was to investigate the relationship between IL‐1 genotype and periodontitis in a prospective longitudinal study in an adult population of essentially European heritage. Methods: From an ongoing study of the Oral Care Research Programme of The University of Queensland, 295 subjects consented to genotyping for IL‐1 allele 2 polymorphisms. Probing depths and relative attachment levels were recorded at baseline, 6, 12, 24, 36, 48 and 60 months using the Florida probe. Periodontitis progression at a given site was defined as attachment loss 2 mm at any observation period during the 5 years of the study and the extent of disease progression determined by the number of sites showing attachment loss. Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans and Prevotella intermedia were detected using ELISA. Results: 38.9% of the subjects were positive for the composite IL‐1 genotype. A relationship between the IL‐1 positive genotype and increased mean probing pocket depth in non‐smokers greater than 50 years of age was found. Further, IL‐1 genotype positive smokers and genotype positive subjects with P. gingivalis in their plaque had an increase in the number of probing depths 3.5 mm. There was a consistent trend for IL‐1 genotype positive subjects to experience attachment loss when compared with IL‐1 genotype negative subjects. Conclusion: The results of this study have shown an interaction of the IL‐1 positive genotype with age, smoking and P. gingivalis which suggests that IL‐1 genotype is a contributory but non‐essential risk factor for periodontal disease progression in this population.
The battle of Alzheimerâ€™s Disease â€“ the beginning of the future Unleashing the potential of academic discoveries (2014)

Alzheimer's Disease (AD) is the most common form of dementia, affecting approximately 36 million people worldwide. To date there is no preventive or curative treatment available for AD, and in absence of major progress in therapeutic development, AD manifests a concrete socioeconomic threat. The awareness of the growing problem of AD is increasing, exemplified by the recent G8 Dementia Summit, a meeting held in order to set the stage and steer the compass for the future. Simultaneously, and paradoxically, we have seen key players in the pharmaceutical industry that have recently closed or significantly decreased their R&D spending on AD and other CNS disorders. Given the pressing need for new treatments in this area, other actors need to step-in and enter this drug discovery arena complementing the industrial efforts, in order to turn biological and technological progress into novel therapeutics. In this article, we present an example of a novel drug discovery initiative that in a non-profit setting, aims to integrate with both preclinical and clinical academic groups and pharmaceutical industry to explore the therapeutic potential of new concepts in patients, using novel biology, state of the art technologies and rapid concept testing.
Improved Simple I-F Open-Loop Start-up of PMSM Drives Without Speed or Position Sensor (2019)

Field-oriented control of PMSM motors without a position or speed sensor is very popular mainly in automotive industry. Many self-sensing/sensorless techniques have been introduced, including saliency-based (high-frequency signal injection) or model-based techniques. This paper focuses on the model-based techniques applications, where an open-loop start-up sequence has to be used. I-F open-loop start-up techniques are discussed. Simulation model and experiments are introduced to explain the open-loop start-up situation in more details. Novel simple current cross-over technique is introduced and tested in concept, indicating positive impact on the start-up reliability especially for low-load or no-load start-up conditions, thus e.g. cooling fan or blower applications.

A magnetometer constructed with an unannealed ribbon, a piezoelectric ceramic driving element and a 100-turn pick-up coil exhibits a minimum detectable magnetic field of 15 nT/√Hz in the DC to 1 Hz bandwidth.
RNA quality analysis of tumor bank specimens and downstream applicability (2012)

Quality of biorepository specimens is a topic of concern. The goal of this project was to evaluate the quality and quantity of RNA obtained from biobanked fresh frozen (FF) and matched formalinfixed paraffin‐embedded (FFPE) tissues. Initially, three human cancer cell lines were used, and then ~50 FF biorepository cancer cases (melanoma, colon, pancreatic) were selected. Histologically similar FFPE tissues were then selected from the original surgical cases. RNA was extracted, quantified with a Nanodrop, and RNA Integrity Number (RIN) was determined using an Agilent Bioanalyzer. Sample RINs generally aligned into 2 groups; ~75% of specimens showed relatively high RINs (90% of melanomas showed RINs of ~8, 70% of colorectal cancers showed RINs of ~6, and 80% of pancreatic cancers showed RINs of ~5). ~25% of samples showed poor RINs (~2–3). RINs were uniformly lower (~2–3) for the matched FFPE samples. Age of FF or FFPE specimens was not related to its RIN. RNA (select cases) was then further analyzed using SA Biosciences housekeeping gene PCR Arrays. dCt (Ct FFPE – Ct FF sample; Ct = cycle threshold) was determined for the 12 housekeeping transcripts. Results showed considerable differences in the dCts between housekeeping genes, and suggested that b‐actin (large dCt) may be useful as a “canary” for predicting suitability for downstream expression analyses.

Effects of Catalyst Precursor Type and Preparation Conditions, and Solvent Type on Activity and Selectivity of Pt/SiO2 Catalyst in Citral Hydrogenation (2011)

In this study, citral hydrogenation reaction in liquid phase over silica gel supported Pt catalysts was investigated. It was desired to hydrogenate carbonyl group selectively to produce valuable unsaturated alcohols, namely geraniol and nerol. Pt/SiO2 catalysts were prepared by impregnation method. The effects of parameters investigated in the present study included Pt precursor type (hexachloroplatinic acid (HCLPA), platinum II acetylacetonate (PAA)), catalyst activation temperature (350°C and 450°C), catalyst activation without calcination, catalyst washing with 0.1 M NaOH and solvent type (ethanol, 2-pentanol). The catalysts activities and selectivities were affected by the type of precursor and activation temperature. The maximum citral conversion (89.50 percent) was achieved at lower activation temperature (350°C) with PAA precursor based catalyst. It was observed that higher activation temperature provided lower citral conversion but higher selectivity to unsaturated alcohols; increasing the activation temperature to 450°C decreased citral conversion to 26.10 percent. But selectivity to unsaturated alcohols, geraniol and nerol, increased from 7.06 to 54.60 percent. Catalyst washing and 2-pentanol prevented acetal formation. Catalyst activation without calcination gave lower citral conversion (20.84 percent) and selectivity to unsaturated alcohols (30.00 percent).
A generic abstract machine for stochastic process calculi (2010)

This paper presents a generic abstract machine for simulating a broad range of process calculi with an arbitrary reaction-based simulation algorithm. The abstract machine is instantiated to a particular calculus by defining two functions: one for transforming a process of the calculus to a set of species, and another for computing the set of possible reactions between species. Unlike existing simulation algorithms for chemical reactions, the abstract machine can simulate process calculi that generate potentially unbounded numbers of species and reactions. This is achieved by means of a just-in-time compiler, which dynamically updates the set of possible reactions and chooses the next reaction in an iterative cycle. As a proof of concept, the generic abstract machine is instantiated for the stochastic pi-calculus, and the instantiation is implemented as part of the SPiM stochastic simulator. The structure of the abstract machine facilitates a significant optimisation by allowing channel restrictions to be stored as species complexes. We also present a novel algorithm for simulating chemical reactions with general distributions, based on the Next Reaction Method of Gibson and Bruck. We use our generic framework to simulate a stochastic pi-calculus model of plasmid co-transfection, where plasmids can form aggregates of arbitrary size and where rates of mRNA degradation are non-exponential. The example illustrates the flexibility of our framework, which allows an appropriate high-level language to be paired with the required simulation algorithm, based on the biological system under consideration.
