description: Electronic health records (EHR's) are only a first step in capturing and utilizing health-related data - the problem is turning that data into useful information. Models produced via data mining and predictive analysis profile inherited risks and environmental/behavioral factors associated with patient disorders, which can be utilized to generate predictions about treatment outcomes. This can form the backbone of clinical decision support systems driven by live data based on the actual population. The advantage of such an approach based on the actual population is that it is "adaptive". Here, we evaluate the predictive capacity of a clinical EHR of a large mental healthcare provider (~75,000 distinct clients a year) to provide decision support information in a real-world clinical setting. Initial research has achieved a 70% success rate in predicting treatment outcomes using these methods.

description: Electron transport in nano-scale structures is strongly influenced by the Coulomb interaction which gives rise to correlations in the stream of charges and leaves clear fingerprints in the fluctuations of the electrical current. A complete understanding of the underlying physical processes requires measurements of the electrical fluctuations on all time and frequency scales, but experiments have so far been restricted to fixed frequency ranges as broadband detection of current fluctuations is an inherently difficult experimental procedure. Here we demonstrate that the electrical fluctuations in a single electron transistor (SET) can be accurately measured on all relevant frequencies using a nearby quantum point contact for on-chip real-time detection of the current pulses in the SET. We have directly measured the frequency-dependent current statistics and hereby fully characterized the fundamental tunneling processes in the SET. Our experiment paves the way for future investigations of interaction and coherence induced correlation effects in quantum transport.

Multiple faults detection and identification of three phase induction motor using advanced signal processing techniques
Creators: name: Memon, Tayab Din
Publisher: name: Torrens University Australia
Year: 2022
Subjects: Automated software engineering

description: In this paper, we have presented the multiple fault detection and identification system for three-phase induction motor. Fast Fourier Transform (FFT) is the most used signal processing technique that offers good frequency information but failing in providing time information and handling multiple faults identification with their occurrence time. FFT also fails to detect non-stationary condition of the signal and unable to convey sudden changes, start and end of the events, drifts and trends. To obtain simultaneous time frequency information and to deal with non-stationary signals Short Time Fourier Transform (STFT) is considered optimal technique that can clearly provide time and frequency information both. In this research work, the multiple fault detection and identification system is presented by employing Short Time Fourier Transform (STFT) signal processing technique. The proposed model is designed using current signature analysis method (CSAM) for three major faults including three phase supply imbalance, single phasing condition and breakage of rotor bars. The system is simulated in MATLAB/SIMULINK and simulation is performed based on healthy and unhealthy conditions of the motor. Comparative analysis between FFT and STFT, shows STFT as a promising approach.

description: We design optimal harmonic-trap trajectories to transport cold atoms without final excitation, combining an inverse engineering techniqe based on Lewis-Riesenfeld invariants with optimal control theory. Since actual traps are not really harmonic, we keep the relative displacement between the center of mass and the trap center bounded. Under this constraint, optimal protocols are found according to different physical criteria. The minimum time solution has a "bang-bang" form, and the minimum displacement solution is of "bang-off-bang" form. The optimal trajectories for minimizing the transient energy are also discussed.

description: The contribution from the residuals of the foreground can have a significant impact on the temperature maps of the Cosmic Microwave Background (CMB). Mostly, the focus has been on the galactic plane, when foreground cleaning has taken place. However, in this paper, we will investigate the possible foreground contamination, from sources outside the galactic plane in the CMB maps. We will analyze the correlation between the Faraday rotation map and the CMB temperature map. The Faraday rotation map is dependent on the galactic magnetic field, as well as the thermal electron density, and both may contribute to the CMB temperature. We find that the standard deviation for the mean cross correlation deviate from that of simulations at the 99.9% level. Additionally, a comparison between the CMB temperature extrema and the extremum points of the Faraday rotation is also performed, showing a general overlap between the two. Also we find that the CMB Cold Spot is located at an area of strong negative cross correlation, meaning that it may be explained by a galactic origin. Further, we investigate nearby supernova remnants in the galaxy, traced by the galactic radio loops. These super nova remnants are located at high and low galactic latitude, and thus well outside the galactic plane. We find some correlation between the Faraday Rotation and the CMB temperature, at select radio loops. This indicate, that the galactic foregrounds may affect the CMB, at high galactic latitudes

description: We present a stellar population study of three HII galaxies (Mrk 36, UM 408, and UM 461) based on the analysis of new ground-based high resolution near-infrared J, H and Kp broad-band and Br narrow-band images obtained with Gemini/NIRI. We identify and determine relative ages and masses of the elementary star clusters and/or star cluster complexes of the starburst regions in each of these galaxies by comparing the colors with evolutionary synthesis models that include the contribution of stellar continuum, nebular continuum and emission lines. We found that the current star cluster formation efficiency in our sample of low luminosity HII galaxies is ~10%. Therefore, most of the recent star formation is not in massive clusters. Our findings seem to indicate that the star formation mode in our sample of galaxies is clumpy, and that these complexes are formed by a few massive star clusters with masses > 10^4 Mo. The age distribution of these star cluster complexes shows that the current burst started recently and likely simultaneously over short time scales in their host galaxies, triggered by some internal mechanism. Finally, the fraction of the total cluster mass with respect to the low surface brightness (or host galaxy) mass, considering our complete range in ages, is less than 1%.

description: In this study, Carpobrotus edulis leaf extract (CELE) has been introduced as a new, eco-friendly, and green inhibitor of copper decomposition in a 3.5 wt.% sodium chloride solution. The water/ethanol extract of the leaves was used to investigate the chemical composition of CELE by the use of liquid chromatography combined with a mass spectrometry detector. Using polarization and electrochemical impedance spectroscopy, the dissolution rate of the copper samples in the presence and absence of various concentrations of CELE (2.5–20 wt.%) were studied, which the best being 20% with an inhibition efficiency of 87%. To evaluate the copper surface morphology and perform surface elemental analysis, scanning electron microscopy and energy dispersive spectroscopy were used. Also, the effect of temperature increment on IE% at the optimum concentration of CELE has been studied, which at 338 K was 57%. Isotherm studies showed that the CELE adsorption mechanism follows the Langmuir isotherm.

description: A brief review of recent progress in the ab intio theory of nuclear pairing is given. Nowdays several successful solutions of the ab intio BCS theory gap equation were published which show that it is a promising first step in the problem. However, the role of many-body correlations that go beyond the BCS scheme remains uncertain and requires further investigations. As an alternative, the semi-microscopic model is discussed in which the effective pairing interaction calculated from the first principles is supplemented with a small phenomenological addendum containing one phenomenological parameter universal for all medium and heavy atomic nuclei.

description: Robust and accurate adhesion level identification is crucial for proper operation of railway vehicle. It is necessary for braking and traction forces characterization, development of maintenance strategies, wheel-rail wear predictions and development of robust onboard health monitoring systems. Adhesion being the function of many uncertain parameters is difficult to model, whereas data driven algorithms such as Deep Neural networks (DNNs) are very good at mapping a nonlinear function from cause to effect. In this research a solid axle Wheel-set was modeled along with different adhesion conditions and a dataset was prepared for the training of DNNs in Python. Furthermore, it explored the potential of DNNs and various data driven algorithms on our noisy sequential dataset for classification task and achieved 91% accuracy in identification of adhesion condition with our final model.
CO emission in optically obscured (type-2) quasars at redshifts z=0.1-0.4

description: We present a search for CO emission in a sample of ten type-2 quasar host galaxies with redshifts of z=0.1-0.4. We detect CO(J=1-0) line emission with >=5sigma in the velocity integrated intensity maps of five sources. A sixth source shows a tentative detection at the ~4.5sigma level of its CO(J=1-0) line emission. The CO emission of all six sources is spatially coincident with the position at optical, infrared or radio wavelengths. The spectroscopic redshifts derived from the CO(J=1-0) line are very close to the photometric ones for all five detections except for the tentative detection for which we find a much larger discrepancy. We derive gas masses of ~(2-16)x10^9Msun for the CO emission in the six detected sources, while we constrain the gas masses to upper limits of Mgas<=8x10^9Msun for the four non-detections. These values are of the order or slightly lower than those derived for type-1 quasars. The line profiles of the CO(J=1-0) emission are rather narrow (<=300km/s) and single peaked, unveiling no typical signatures for current or recent merger activity, and are comparable to that of type-1 quasars. However, at least one of the observed sources shows a tidal-tail like emission in the optical that is indicative for an on-going or past merging event. We also address the problem of detecting spurious ~5sigma emission peaks within the field of view.

Fuzzy logic based anti-slip control of commuter train with FPGA implementation

Publisher: name: Torrens University Australia
Year: 2022
Subjects: Fuzzy computation

description: In the railway industry, slip control has always been essential due to the low friction and low adhesion between the wheels and the rail and has been an issue for the design, activity, and operation of railroad vehicles. Slip is an unpredictable parameter in the railroad that disintegrates the surface of the railroad with a contact surface of the boggy wheel brought about by the mechanical force of traction phenomena, it destabilizes the railway traction which does not fulfill safety and punctuality requirements. In this paper, we present the work based on developing a fuzzy logic-based anti-slip controller for the commuter train using FPGA implementation which minimizes slip parameters. The development of a fuzzy logic- based anti-slip controller for the commuter train is designed in MATLAB and then tested for area-performance parameters in FPGA through the system generator library. Simulation is performed to demonstrate the effectiveness of the proposed fuzzy logic control system for anti-slip control under various parameters, the results of simulation prove the effectiveness of the proposed control system as compared with conventional PID controller and shows high anti-slip control performance under nonlinearity of brake dynamics.

description: We obtain the patch-repetition entropy Sigma within the Random First Order Transition theory (RFOT) and for the square plaquette system, a model related to the dynamical facilitation theory of glassy dynamics. We find that in both cases the entropy of patches of linear size l, Sigma(l), scales as s_c l^d+A l^{d-1} down to length-scales of the order of one, where A is a positive constant, s_c is the configurational entropy density and d the spatial dimension. In consequence, the only meaningful length that can be defined from patch-repetition is the cross-over length xi=A/s_c. We relate xi to the typical length-scales already discussed in the literature and show that it is always of the order of the largest static length. Our results provide new insights, which are particularly relevant for RFOT theory, on the possible real space structure of super-cooled liquids. They suggest that this structure differs from a mosaic of different patches having roughly the same size.

description: We report on the detection of bright CO(4-3) line emission in two powerful, obscured quasars discovered in the SWIRE survey, SW022513 and SW022550 at z>3.4. We analyze the line strength and profile to determine the gas mass, dynamical mass and the gas dynamics for both galaxies. In SW022513 we may have found the first evidence for a molecular, AGN-driven wind in the early Universe. The line profile in SW022513 is broad (FWHM = 1000 km/s) and blueshifted by -200 km/s relative to systemic (where the systemic velocity is estimated from the narrow components of ionized gas lines, as is commonly done for AGN at low and high redshifts). SW022550 has a more regular, double-peaked profile, which is marginally spatially resolved in our data, consistent with either a merger or an extended disk. The molecular gas masses, 4x10^10 Msun, are large and account for <30% of the stellar mass, making these obscured QSOs as gas rich as other powerful CO emitting galaxies at high redshift, i.e., submillimeter galaxies. Our sources exhibit relatively lower star-formation efficiencies compared to other dusty, powerful starburst galaxies at high redshift. We speculate that this could be a consequence of the AGN perturbing the molecular gas.

description: We study the effect of nonlocal optical response on the optical properties of metallic nanowires, by numerically implementing the hydrodynamical Drude model for arbitrary nanowire geometries. We first demonstrate the accuracy of our frequency-domain finite-element implementation by benchmarking it in a wide frequency range against analytical results for the extinction cross section of a cylindrical plasmonic nanowire. Our main results concern more complex geometries, namely cylindrical and bow-tie nanowire dimers that can strongly enhance optical fields. For both types of dimers we find that nonlocal response can strongly affect both the field enhancement in between the dimers and their respective extinction cross sections. In particular, we give examples of maximal field enhancements near hybridized plasmonic dimer resonances that are still large but nearly two times smaller than in the usual local-response description. At the same time, for a fixed frequency the field enhancement and cross section can also be significantly more enhanced in the nonlocal-response model.

Fpga’s dual-port rom-based 8x8 multiplier for area optimized implementation of dsp systems
Creators: name: Memon, Tayab Din
Publisher: name: Torrens University Australia
Year: 2022
Subjects: Query processing and optimisation

description: FPGA’s block memory may be programmed as a single or dual-port RAM/ROM module that leads to an area-efficient implementation of memory-based systems. In this contest, various works of carrying out an optimized implementation of simple to complex DSP systems on embedded building blocks may be seen. The multiplier is a core element of the DSP systems, and in implementing a memory-based multiplier, it is observed that one of the operands is kept constant, hence leading the design to a constant-coefficient multiplication. This paper shows Virtex-7 FPGA’s dual-port ROM-based implementation of an 8x8 variable-coefficient multiplier that may be used in several simple to complex DSP applications. The novelty of the proposed design is to configure the block ROM in dual-port mode and, hence, get four partial products in two clock cycles and introduce two unconventional adder approaches for partial product addition. This approach leads to fully resource utilization and the provision of a variable-coefficient multiplier. The work also shows the comparison of proposed architecture with already existing memory-based implementations and concludes the work as a novel step towards the efficient memory-based implementation of multiplier core.

description: Digital filters are the most significant part of signal processing that are used in enormous applications such as speech recognition, acoustic, adaptive equalization, and noise and interference reduction. It would be of great benefit to implement adaptive FIR filter because of self-optimization property, linearity and frequency stability. Designing FIR filter involves multi-modal optimization problems whereas conservative gradient optimization technique is not useful to design the filter. Hence, Particle Swarm Optimization (PSO) algorithm is more flexible and optimization technique based on population of particles in search space and alternative approach for linear phase FIR filter design. PSO improves the solution characteristic by giving a novel method for updating swarm's position and velocity vector. Set of optimized filter coefficients will be generated by PSO algorithm. In this paper, PSO based FIR Low pass filter is efficiently designed in MATLAB and further Xilinx System Generator tool is used to efficiently design, synthesize and implement FIR filter in FPGA using SPARTEN 3E kit. For an example specifications, output of PSO algorithm is obtained that is set of optimized coefficients whose response is approximating to the ideal response. Hence, functional verification of the proposed algorithm has been performed and the error between obtained filter and ideal filter is minimized successfully. This work demonstrates the effectiveness of the PSO algorithms in parallel processing environment as compared to the Remez Exchange algorithm.

Under some conditions, using the coupled fixed point theorem of Bhaskar and Lakshmikantham, we establish the existence and uniqueness of Hermitian positive definite solution for such equation. Moreover, we provide an iteration method to find convergent sequences which converge to the solution if one exists.

description: We study the low temperature tunneling density of states of thin wires where superconductivity is destroyed through quantum phase-slip proliferation. Although this regime is believed to behave as an insulator, we show that for a large temperature range this phase is characterized by a conductivity falling off at most linearly with temperature, and has a gapless excitation spectrum. This novel conducting phase results from electron-electron interaction induced pair breaking. Also, it may help clarify the low temperature metallic features found in films and wires whose bulk realization is superconducting.

However, the off-the-shelf nature of ChEVAR makes it a good option for emergent AAA repair. We report our institutional experience in ChEVAR in an urgent setting. METHODS: ChEVAR procedures were collected from 2019 to 2023 in a tertiary hospital, and a retrospective analysis was performed. This includes gathered information from electronic medical records, surgical reports and the picture archiving system. Descriptive statistics were applied. The main endpoints were technical success, 30-day and 1-year survival. RESULTS: Five patients were submitted to urgent aneurysm repair using the chEVAR technique. Average age was 73,4 years and all patients were male. Arterial hypertension was present in 100% patients and all patients were ASA 4. Indications for surgery were post EVAR type 1a endoleak with associated rupture or abdominal pain in two patients; symptomatic/contained rupture of pararenal AAA in two patients; and contained rupture of a thoracoabdominal aneurysm in one patient. A total of eight target vessels were catheterized: two patients required single-vessel chimney and the remainder two-vessel chimney. Target vessels were two superior mesenteric arteries and six renal arteries. Technical success rate was 100% and 30-day mortality was 0%. There were no major complications. Follow-up time is 20.2 months (4.7-38). Target vessel patency during the follow-up period was 87.5%. Three patients (60%) died due to non-aortic related pathologies, on average 18 months after surgery (4.7-38), with a 1-year survival of 80%. CONCLUSION: Our experience with ChEVAR for emergent AAA repair is satisfactory, with high technical success rates and low short-term mortality. Sac regression, low rates of target vessel occlusion and type 1a endoleaks reveal a favourable profile for aneurysm exclusion. ChEVAR is a viable option in emergent setting for patients unfit for open repair.

description: Preventive maintenance is one of the main concerns in modern industry, in which early failure detection increases the lifecycle of machines. In this paper, electrical signature analysis is employed to indicate the development or existence of faults within the proposed system and this is achieved by embedding a real-time frequency analysis of the motor current. The term in the title electrical signature analysis basically refers to the motor current or voltage attributes are being used as a transducers to detect the changes in their spectrum in both the conditions; healthy and unhealthy. The algorithm used for analyzing the signals in frequency domain is done using Fast Fourier transform. In this work, we have focused on failure of bearing part of single phase induction motor and developed hardware for monitoring conditions (i.e. health of the motor) in run time. Because of the simplicity of this technique the mechanism of fault diagnosis is employed using an FPGA approach that offers re-configurability. This work can be very useful in industrial setup where there are 100 motors working together for some production lines. The findings show promising results which could lead to better reliability performance of the induction motor and lower maintenance costs.

description: Introduction: Peripheral arterial disease has become a worldwide problem, with chronic limb-threatening ischemia(CLTI) being its most extreme manifestation. Recently, endovascular strategies evolved and became the first approach in many revascularization procedures. However, infrapopliteal (IP) disease is still a therapeutic challange.1–3 This study aims to present a surgical technique, named inverted T bypass, that can be applied to patients with: an IP artery with poor collateralization to the foot, an inframalleolar artery with poor runoff and availability of only a short venous graft.4 Methods: A single-center retrospective analysis of all patients submitted to inverted T bypass. The end points of the present study were limb-based patency(LBP), primary patency(PP) and secondary patency(SP) rates, freedom from CLTI, recurrence of CLTI, freedom from major index limb amputation, amputation free-survival, and overall survival. Results: A total of twenty-five patients with CLTI (68% male) with a median age of 77 years were submitted to 25 inverted T bypasses. The median follow-up was 25 months(interquartile range of 32). Twenty-one preoperative angiographies were performed. Severe femoropopliteal (FP) and IP anatomic patterns(GLASS FP and IP grade 4) were predominant(57% and 86%, respectively) with 100% of limbs classified as GLASS stage III. Three patients(12%) had previously failed endovascular treatment. LBP, PP and SP were, respectively, 75%, 75% and 79% at 1 year, and 61%, 61% and 64% at 2 years. After one year, 86% of the limbs were free from CLTI and 79% of them remained without recurrences during a follow-up of 2 years. Eighty-one percent of the patients were free from major index limb amputation at 2 years. Conclusion: The inverted T bypass is a creative surgical solution for CLTI patients with poor runoff and lacking an adequate venous graft. The results are promising, rendering this technique a viable option for distal and ultra-distal revascularization in complex cases.

description: Two identical autonomous dynamical systems coupled in a master-slave configuration can exhibit anticipated synchronization (AS) if the slave also receives a delayed negative self-feedback. Recently, AS was shown to occur in systems of simplified neuron models, requiring the coupling of the neuronal membrane potential with its delayed value. However, this coupling has no obvious biological correlate. Here we propose a canonical neuronal microcircuit with standard chemical synapses, where the delayed inhibition is provided by an interneuron. In this biologically plausible scenario, a smooth transition from delayed synchronization (DS) to AS typically occurs when the inhibitory synaptic conductance is increased. The phenomenon is shown to be robust when model parameters are varied within physiological range. Since the DS-AS transition amounts to an inversion in the timing of the pre- and post-synaptic spikes, our results could have a bearing on spike-timing-dependent-plasticity models.

description: It is the right time to embark upon wireless sensor networks to overcome problems of the structures safety by analyzing them precisely using structural health monitoring techniques. This research lays emphasis on the development of an IOT based smart instrumentation for analyzing the health structure based on simple accelerometer (ADXL320) and MCU node. The accelerometer sensing paves way in determining the health structure by observing the non-linear vibrations in the structure. The real-time data acquired from the sensor is transmitted to a cloud platform (Thingspeak) using a secure API communication that helps client to observe the frequency response of the entire structure remotely. The developed instrumentation is a power efficient, low cost solution having a latency of 15 s, and remarkably efficient.

description: We study curvature functionals for immersed 2-spheres in non-compact, three-dimensional Riemannian manifold $(M,h)$ without boundary. First, under the assumption that $(M,h)$ is the euclidean 3-space endowed with a semi-perturbed metric with perturbation small in $C^1$ norm and of compact support, we prove that if there is some point $\bar{x} \in M$ with scalar curvature $R^M(\bar{x})>0$ then there exists a smooth embedding $f:S^2 \hookrightarrow M$ minimizing the Willmore functional $1/4\int |H|^2$, where $H$ is the mean curvature. Second, assuming that $(M,h)$ is of bounded geometry (i.e. bounded sectional curvature and strictly positive injectivity radius) and asymptotically euclidean or hyperbolic we prove that if there is some point $\bar{x} \in M$ with scalar curvature $R^M(\bar{x})>6$ then there exists a smooth immersion $f:S^2 \hookrightarrow M$ minimizing the functional $\int (1/2|A|^2+1)$, where $A$ is the second fundamental form. Finally, adding the bound $K^M \leq 2$ to the last assumptions, we obtain a smooth minimizer $f:S^2 \hookrightarrow M$ for the functional $\int (1/4|H|^2+1)$. The assumptions of the last two theorems are satisfied in a large class of 3-manifolds arising as spacelike timeslices solutions of the Einstein vacuum equation in case of null or negative cosmological constant.
