description: Removal of Poisson noise is one of the challenging task’s in medical imaging. This work aims to evaluates, analyze and compare the medical images de-noising techniques and methodologies, giving a detail explanation, depicting the main points and the performance metrics for poison noise removal. In this context the performance of Non Local Mean, Wavelet transform and logarithm gradient representative flavors are analyzed. Non Local Mean (NLM) filter consists of three variants based on the fact that third order moment of the image makes the signal and the noise clearer and easier to be de-noised. In second approach, Discrete Wavelet Transform (DWT) with modified thresholding function is utilized for Poisson noise reduction. The third method is based on Hybrid Logarithmic Gradient. These methods are used on medical images i.e. X-Rays, PET, SPECT and general images. Experimental results are evaluated in terms of correlation comparison of all methods.

description: Upper bounds are given for the weight distribution of binary weakly self-dual codes. To get these new bounds, we introduce a novel method of utilizing unitary operations on Hilbert spaces. This method is motivated by recent progress on quantum computing. This new approach leads to much simpler proofs for such genre of bounds on the weight distributions of certain classes of codes. Moreover, in some cases, our bounds are improvements on the earlier bounds. These improvements are achieved, either by extending the range of the weights over which the bounds apply, or by extending the class of codes subjected to these bounds.

description: We propose to search for millicharged particles in electron colliders operated with the center-of-mass energies at ${\cal O}$(1-10) GeV, which include Belle II, BESIII, BaBar, and also the proposed experiment STCF. We use the monophoton final state at electron colliders to probe the parameter space of millicharged particles, that is spanned by millicharge $ε$ and mass $m$. We find that electron colliders have sensitivity to the previously unexplored parameter space for millicharged particles with MeV-GeV mass: $ε\lesssim {\cal O}(10^{-1})$ for $0.5$ GeV $\lesssim m \lesssim 3.5$ GeV in BaBar, $ε\lesssim {\cal O}(10^{-3})$ for $0.1$ GeV $\lesssim m \lesssim 1.5$ GeV in BESIII, $ε\lesssim 10^{-3}-10^{-2}$ for $0.1$ GeV $\lesssim m \lesssim 4$ GeV in Belle II, and $ε\lesssim {\cal O}(10^{-4})$ for $1$ MeV $\lesssim m \lesssim 1$ GeV in STCF.

description: A 2-D Adaptive Trimmed Mean Autoregressive (ATMAR) model has been proposed for denoising of medical images corrupted with Poisson noise. Unfiltered images are divided into smaller chunks and ATMAR model is applied on each chunk separately. In this paper, two 5x5 windows with 40% overlap are used to predict the center pixel value of the central row. The AR coefficients are updated by sliding both windows forward with 60% shift. The same process is repeated to scan the entire image for prediction of a new denoised image. The Adaptive Trimmed Mean Filter (ATMF) eradicates the lowest and highest variations in pixel values of the ATMAR model denoised image and also average out the remaining neighborhood pixel values. Finally, power-law transformation is applied to the resultant image of the ATMAR model for contrast stretching. Image quality is judged in terms of correlation, Mean Squared Error (MSE), Structural Similarity Index Measure (SSIM) and Peak Signal to Noise Ratio (PSNR) of the image with latest denoising techniques. The proposed technique showed an efficient way to scale down Poisson noise in scintigraphic images on a pixel-by-pixel basis. The highest correlation 0.9706, PSNR 10.023 and MSE 25.902 is achieved by the proposed technique.

description: Aims: The costs associated with insulin therapy and diabetes-related complications represent a significant and growing economic burden for healthcare systems. The aim of this study was to evaluate the cost-effectiveness of switching to insulin degludec (degludec) vs continuing previous basal insulin, in Italian patients with type 1 (T1D) or type 2 (T2D) diabetes, using a long-term economic model. Materials and methods: Data were retrieved from a real-world population of patients from clinical practice in Italy. Clinical parameters included in the base-case model were change from baseline in HbA1c, rates of hypoglycemia, and basal and bolus insulin dose, at 6 months following switch to degludec. Costs of treatments were taken from official Italian pharmaceutical list prices and costs of hypoglycemia were based on the literature. The data were used to populate a long-term (lifetime) IQVIA CORE Diabetes Model to evaluate the incremental cost-effectiveness ratio (ICER) – cost per quality-adjusted life-year (QALY). The robustness of these results was tested with extensive sensitivity analyses by varying the time horizons and abolishing each of the treatment differences and previous basal insulins. Results: The total incremental cost for degludec vs previous basal insulin was €–6,310 and €–2,682 for patients with T1D and T2D, respectively; the switch to degludec resulted in a QALY gain of 0.781 and 0.628. The long-term ICER for degludec vs continuing the previous basal insulin regimen showed that degludec was dominant for both T1D and T2D, meaning that patient health was improved in terms of QALYs with lower healthcare costs. Sensitivity analyses showed that degludec remained dominant in most scenarios including after elimination of any benefit in non-severe hypoglycemia and insulin dose, in both T1D and T2D. Conclusions: Under routine care, switching to degludec is dominant, compared with continuing previous basal insulin, in Italian patients with T1D or T2D.

description: We propose to subject two Bose-Einstein condensates to a periodic potential, so that one condensate undergoes the Mott insulator transition to a state with precisely one atom per lattice site. We show that photoassociation of heteronuclear molecules within each lattice site is described by the quantum optical Jaynes-Cummings Hamiltonian. In analogy with studies of this Hamiltonian with cavity fields and trapped ions, we are thus able to engineer quantum optical states of atomic matter wave fields and we are able to reconstruct these states by quantum state tomography.

description: In this article, we extend our previous study of the $π$-$π$ scattering lengths under the presence of an external magnetic field, including finite temperature effects. The novelty of this work is precisely the introduction of temperature into the discussion, and its interplay with the magnetic field. As in the previous article, we base our analysis in the linear sigma-model, and our calculations are exact within this context. Although the effects are comparatively small, it is interesting to remark that magnetic field and temperature display opposite effects over the scattering lengths.

description: The creation of a marine reserve network is an active area of policy in Australia. Successful policy hinges on community support, which requires an understanding of what drives improvements in social welfare. Here, a discrete choice experiment is used to estimate ecological values for the Ningaloo Marine Park. A novel aspect of this research is that it not only considers the values people hold for conservation outcomes, but also their preferences for how those outcomes are achieved. By considering management process within the choice model, we gain a richer understanding of the relationship between social welfare and marine conservation. The results indicate that management process does have an impact on individuals’ preferences for conservation.

description: Retinal damage caused due to complications of diabetes is known as a
Diabetic Retinopathy (DR). In this case, the vision is obscured due to damage of tiny
retinal blood vessels. These tiny blood vessels may cause leakage that affect the vision
and can lead to complete blindness. Identification of these new retinal vessels and their
structure is an essential for analysis of DR. Automatic blood vessel segmentation plays a
significant role to assist subsequent automatic methodologies that aid to such analysis. In
literature, most authors have used computationally-hungry strong preprocessing steps
followed by a simple thresholding and postprocessing steps. This paper proposed an
arrangement of simple preprocessing steps that consist of Contrast Limited Adaptive
Histogram Equalization (CLAHE) for contrast enhancement and a difference image of
green channel from its Gaussian blur filtered image to remove local noise or geometrical
objects. The proposed Modified Iterative Self Organizing Data Analysis Technique
(MISODATA) has been used for segmentation of vessel and non-vessel pixels based on
global and local thresholding. Finally, postprocessing steps have been applied using
region properties (area, eccentricity) to eliminate the unwanted regions/segments, nonvessel
pixels, and noise. A novel postprocessing steps are used to reject misclassified
foreground pixels. The strategy has been tested on the openly accessible DRIVE (Digital
Retinal Images for Vessel Extraction) and STARE (STructured Analysis of the REtina)
databases. The average accuracy rates of 0.952 and 0.957 with average sensitivity rates
0.780 and 0.745 along with average specificity rates of 0.972 and 0.974 were obtained on
DRIVE and STARE datasets, respectively. The performance of the proposed technique
has been assessed comprehensively. The acquired accuracy, robustness, low complexity,
and high efficiency make the method an efficient tool for an automatic retinal image
analysis. The proposed technique perform well as compared to the existing strategies on
the online available databases in term of accuracy, sensitivity, specificity, false positive
rate, true positive rate, and area under receiver operating characteristic (ROC) curve.

description: We investigate the dependence of the nucleon-nucleon force in the deuteron system on the values of coupling strengths at high energy, which will in general depend on the geometry of extra dimensions. The stability of deuterium at all times after nucleosynthesis sets a bound on the time variation of the ratio of the QCD confinement scale to light quark masses. We discuss the relation between this ratio, which is exponentially sensitive to high-energy couplings, and fundamental parameters, in various classes of unified theory. The binding energy of the deuteron is also expected to have an important effect on nucleosynthesis and we quantify this effect.

description: The focus of the research reported in this paper has been to estimate recreation values for beaches over approximately 1400 kilometres of coastline along the Queensland coast. The study is notable at an international level because it assesses recreation values to a general type of recreation asset rather than to a specific site, and because it focuses on the values of the local resident population. Negative binomial models have been used to estimate both the visit rate and recreation values associated with beach visits in different regional areas. The value of a single beach visit was estimated per person at $35.09, which extrapolates to $450 million in beach recreation values per annum. These values are likely to be conservative because opportunity costs incurred to live closer to the beach (e.g. housing premiums) have not been assessed. Contingent behaviour models were used to estimate the values of potential declines in water quality, with marginal effects assessed at $1.30 per recreation trip to avoid each 1% decline in water quality.

description: The G0V star HD166435 has been observed by the fiber-fed spectrograph ELODIE as one of the targets in the large extra-solar planet survey that we are conducting at the Observatory of Haute-Provence. We detected coherent, low-amplitude, radial-velocity variations with a period of 3.7987days, suggesting a possible close-in planetary companion. Subsequently, we initiated a series of high-precision photometric observations to search for possible planetary transits and an additional series of CaII H and K observations to measure the level of surface magnetic activity and to look for possible rotational modulation. Surprisingly, we found the star to be photometrically variable and magnetically active. A detailed study of the phase stability of the radial-velocity signal revealed that the radial-velocity variability remains coherent only for durations of about 30days. Analysis of the time variation of the spectroscopic line profiles using line bisectors revealed a correlation between radial velocity and line-bisector orientation. All of these observations, along with a one-quarter cycle phase shift between the photometric and the radial-velocity variationss, are well explained by the presence of dark photospheric spots on HD166435. We conclude that the radial-velocity variations are not due to gravitational interaction with an orbiting planet but, instead, originate from line-profile changes stemming from star spots on the surface of the star. The quasi-coherence of the radial-velocity signal over more than two years, which allowed a fair fit with a binary model, makes the stability of this star unusual among other active stars. It suggests a stable magnetic field orientation where spots are always generated at about the same location on the surface of the star.

description: Gravitational wave (GW) detection is now commonplace and as the sensitivity of the global network of GW detectors improves, we will observe $\mathcal{O}(100)$s of transient GW events per year. The current methods used to estimate their source parameters employ optimally sensitive but computationally costly Bayesian inference approaches where typical analyses have taken between 6 hours and 5 days. For binary neutron star and neutron star black hole systems prompt counterpart electromagnetic (EM) signatures are expected on timescales of 1 second -- 1 minute and the current fastest method for alerting EM follow-up observers, can provide estimates in $\mathcal{O}(1)$ minute, on a limited range of key source parameters. Here we show that a conditional variational autoencoder pre-trained on binary black hole signals can return Bayesian posterior probability estimates. The training procedure need only be performed once for a given prior parameter space and the resulting trained machine can then generate samples describing the posterior distribution $\sim 6$ orders of magnitude faster than existing techniques.

description: {\it Ab-initio} studies of the stability of orbital ordering, its coupling to magnetic structure and its possible origins (electron-phonon and/or electron-electron interactions) are reported for two perovskite systems, LaMnO$_3$ and KCuF$_3$. We present a new Average Spin State (ASS) calculational scheme that allowed us to treat a paramagnetic state. Using this scheme, we succesfully described the experimental magnetic/orbital phase diagram of both LaMnO$_3$ and KCuF$_3$ in crystal structures when the Jahn-Teller distortions are neglected. Hence, we conclude that the orbital ordering in both compounds is purely electronic in origin.

description: Stretched words like `heellllp' or `heyyyyy' are a regular feature of spoken language, often used to emphasize or exaggerate the underlying meaning of the root word. While stretched words are rarely found in formal written language and dictionaries, they are prevalent within social media. In this paper, we examine the frequency distributions of `stretchable words' found in roughly 100 billion tweets authored over an 8 year period. We introduce two central parameters, `balance' and `stretch', that capture their main characteristics, and explore their dynamics by creating visual tools we call `balance plots' and `spelling trees'. We discuss how the tools and methods we develop here could be used to study the statistical patterns of mistypings and misspellings, along with the potential applications in augmenting dictionaries, improving language processing, and in any area where sequence construction matters, such as genetics.

description: The $α$ inelastic scattering on $^{16}$O is investigated with the coupled-channel calculation using the $α$-nucleus coupled-channel potentials, which are microscopically derived by folding the the Melbourne $g$-matrix $NN$ interaction with the $^{16}$O and $α$ densities. The matter and transition densities of $^{16}$O are calculated by a microscopic structure model of the variation after the spin-parity projections combined with the generator coordinate method of $^{12}$C+$α$ in the framework of the antisymmetrized molecular dynamics. The calculation reproduces the observed elastic and inelastic cross sections at incident energies of $E_α$=104 MeV, 130 MeV, 146 MeV, and 386 MeV. The coupled-channel effect on the cross sections is also discussed.

description: Noise in signals and images can be removed through different de-noising
techniques such as mean filtering, median filtering, total variation and filtered variation
techniques etc. Wavelet based
de-noising is one of the major techniques used for noise removal. In the first part of our
work, wavelet transform based logarithmic shrinkage technique is used for de-noising of
images, corrupted by noise (during under-sampling in the frequency domain). The logarithmic
shrinkage technique is applied to under-sampled Shepp–Logan Phantom image.
Experimental results show that the logarithmic shrinkage technique is 7–10% better in
PSNR values than the existing classical techniques. In the second part of our work we denoise
the noisy, under-sampled phantom image, having salt and pepper, Gaussian, speckle
and Poisson noises through the four thresholding techniques and compute their correlations
with the original image. They give the correlation values close to the noisy image. By
applying median or wiener filter in parallel with the thresholding techniques, we get
30–35% better results than only applying the thresholding techniques individually. So, in
the second part we recover and de-noise the sparse under-sampled images by the combination
of shrinkage functions and median filtering or wiener filtering.

description: We are exploring the extended stellar distributions of Galactic satellite galaxies and globular clusters. For seven objects studied thus far, the observed profile departs from a King function at large r, revealing a ``break population'' of stars. In our sample, the relative density of the ``break'' correlates to the inferred M/L of these objects. We discuss opposing hypotheses for this trend: (1) Higher M/L objects harbor more extended dark matter halos that support secondary, bound, stellar ``halos''. (2) The extended populations around dwarf spheroidals (and some clusters) consist of unbound, extratidal debris from their parent objects, which are undergoing various degrees of tidal disruption. In this scenario, higher M/L ratios reflect higher degrees of virial non-equilibrium in the parent objects, thus invalidating a precept underlying the use of core radial velocities to obtain masses.

description: The crowd phenomenon frequently occurs in dense urban living environments. Crowd counting or
estimation helps to develop management strategies such as designing safe public places and evacuation
plan for emergencies. These strategies are different depending upon the type of event such
as political and public demonstrations, sports, and religious events. However, estimating the number
of people in crowds at closed or open environments is quite challenging because of the dynamics
involved in the process. In addition, crowd estimation itself poses challenges due to randomness in
crowd behavior, motion, and an area’s geometric specifications. Crowd behavior as well as the area
parameters is studied before suggesting any possible technological solution for managing a crowd.
This article presents a theoretical understanding of the major crowd size estimation approaches that
cannot be achieved through the study of existing survey papers in this area, because the existing
survey papers focus on particular technologies/specific areas with no or brief description of the
involved steps. Besides, this article also highlights the strength and weakness of crowd size estimation
solutions and their possible applications. It is, therefore, believed that the provided information
would assist in developing an intelligent system for crowd management.

description: Point-contact spectroscopy measurements on magnesium diboride reveal the existence of two superconducting energy gaps closing at the same transition temperature in line with the multiband model of superconductivity. The sizes of the two gaps ($Δ_π$ = 2.8 meV and $Δ_σ$ = 6.5-7 meV) are respectively smaller and larger than the expected weak coupling value of the one-gap superconductor. The smaller gap is rapidly filled by a small magnetic field of about 1-2 Tesla much lower than the real upper critical field $H_{c2}$. The larger gap is closed at the anisotropic $H_{c2}$. Above the gap energies reproducible non-linearities are observed at the characteristic phonon energies of MgB$_2$.

description: We propose a Weighted Gradient Filter for denoising of Poisson noise in medical images. In a predefined window, gradient of the centre pixel is averaged out. Gaussian Weighted filter is used on all calculated gradient values. Proposed method is applied on biomedical images X-Rays and then on different general images of LENA and Peppers. Recovery results show that the proposed weighted gradient filter is efficient and has better visual appearance. Moreover, proposed method is computationally very efficient and faster than Non Local Mean (NLM) filter which is an advanced technique for Poisson noise removal. Proposed method results are also better in terms of performance measures parameters i.e. correlation, Peak Signal-to-Noise Ratio (PSNR), Maximum Structural Similarity Index Measure (MSSIM) and Mean Square Error (MSE) than the conventional Median, Wiener and NLM filter.
Measurements and calculations of reaction losses of medium-energy protons in NaI detectors

description: Reaction losses of protons in NaI have been directly measured at 86, 133. and 146 MeV. Calculations of the expected tail-to-peak ratios were made over the range 40 to 240 MeV using recent total reaction cross-section data for sodium and iodine. The calculated ratios agree well with the data and are slightly larger than the previously calculated values of Measday and Richard-Serre.
