Accrual and Dismemberment of Brain Tumours Using Fuzzy Interface and Grey Textures for Image Disproportion

A neurological disorder is a problem with the neural system of the body, as a brain tumor is one of the deadliest neurological conditions and it requires an early and effective detection procedure. The existing detection and diagnosis methods for image evaluation are based on the judgment of the radiologist and neurospecialist, where a risk of human mistakes can be found. Therefore, a new flanged method and methodology for detecting brain tumors using magnetic resonance imaging and the artificial neural network (ANN) technique are applied. The research is based on an artificial neural network-based behavioral examination of neurological disorders. In this study, an artificial neural network is used to detect a brain tumor as early as possible. The current work develops an effective approach for detecting cancer from a given brain MRI and recognizing the retrieved data for further use. To obtain the desired result, the following three procedures are used: preprocessing, feature extraction, training, and detection or classification. A Gaussian filter is also incorporated to eliminate noise from the image, and for texture feature extraction, GLCM is considered in this study. Further entropy, contrast, energy, homogeneity, and other GLCM texture properties of tumor categorization are measured using the ANFIS approach, which determines if the tumor is normal, benign, or malignant. Future research will focus on applying advanced texture analysis to classify brain tumors into distinct classes in order to improve the accuracy of brain tumor diagnosis. In the future, MRI brain imaging will be used to classify metastatic brain tumors.
THE RISE AND FALL OF THE BUREAUCRATIC BOURGEOISIE: PUBLIC SECTOR EMPLOYEES AND ECONOMIC PRIVILEGE IN POSTCOLONIAL KENYA AND TANZANIA

: In 1961, Frantz Fanon scathingly characterised the emerging African elite as a bourgeoisie of the civil service. Many have since described Africa ’ s public sector employees as a rentier class that grew disproportionately large in relation to the continent ’ s underdeveloped private sector. Is this characterisation still accurate? Using educational data and household budget surveys from Kenya and Tanzania, this article situates public sector employees within their respective educational hierarchies and national income distributions over time. It ﬁ nds that since independence, the share of public sector employees at the top of these distributions has declined. The corollary to this is an increase in the share of private sector employees and business owners at the top, providing some cautious support for the notion of a rising private sector upper and middle class. © 2020 The Authors.

DuQuad: an inexact (augmented) dual first order algorithm for quadratic programming

In this paper we present the solver DuQuad specialized for solving general convex quadratic problems arising in many engineering applications. When it is difficult to project on the primal feasible set, we use the (augmented) Lagrangian relaxation to handle the complicated constraints and then, we apply dual first order algorithms based on inexact dual gradient information for solving the corresponding dual problem. The iteration complexity analysis is based on two types of approximate primal solutions: the primal last iterate and an average of primal iterates. We provide computational complexity estimates on the primal suboptimality and feasibility violation of the generated approximate primal solutions. Then, these algorithms are implemented in the programming language C in DuQuad, and optimized for low iteration complexity and low memory footprint. DuQuad has a dynamic Matlab interface which make the process of testing, comparing, and analyzing the algorithms simple. The algorithms are implemented using only basic arithmetic and logical operations and are suitable to run on low cost hardware. It is shown that if an approximate solution is sufficient for a given application, there exists problems where some of the implemented algorithms obtain the solution faster than state-of-the-art commercial solvers.

On invariant surfaces and bifurcation of periodic solutions of ordinary differential equations

This article consists of Chapter 2 of the author's 1954 Dissertation bearing the same title and published as Courant Institute report IMM-NYU 333, available in full on the author's personal web site. Chapter 2 consists of the first complete proof of what has come to be known as the Neimark-Sacker bifurcation theorem. It includes the reduction to normal form using weighted monomials which precludes using the Center Manifold theorem which was not known to the author and was published the same year as the dissertation and called “a Reduction Principle” by V. Pliss and later named Center Manifold theorem by A. Kelley (see previous article for citations). After reduction to normal form, the resulting functional equations for the bifurcating invariant curve is solved in detail. Stand-alone decimals provide solutions of linear functional equations, a-priori estimates and interpolation inequalities between derivatives in the sup norm.
Computational study of kaurene diterpenoids for antivirals against SARS-CoV-2

Kaurene diterpenoids were found in some plants such as Adenostemma lavenia and Pteris semipinnata to have antioxidant, antiinflammatory, anticancer, antitumor, cytotoxic, and antiviral activities. To evaluate the potency of kaurene diterpenoids as antivirals against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we conducted an in silico study of several kaurene diterpenoids and antiviral drugs such as remdesivir and favipiravir in inhibition essential SARS-CoV-2 proteins including 3CLpro, Plpro, nucleocapsid (N), and membrane (M) through molecular docking, molecular dynamic (MD) simulations, adsorption, distribution, metabolism, excretion, and toxicity (ADMET), and pharmacokinetic properties prediction using a number of pieces of software. The docking study showed that the kaurene diterpene glycosides have a higher binding affinity to the 3CLpro, N, and M proteins of SARS-CoV-2 than other kaurene diterpenoids and even antiviral drugs such as remdesivir and favipiravir. Inhibition of these nonstructural and structural proteins has a significant impact on disrupting the viral replication and viral assembly of SARS-CoV-2. Almost all the complexes showed minimum deviation and fluctuation, indicating that each ligand is strongly bound to the binding site of proteins. ADMET prediction revealed all kaurene diterpenoids were well absorbed by the human intestine, noncarcinogenic, and did not cause mutations in DNA. Therefore, we expected these materials could be a potential preventive and therapeutic agent in the fight against the COVID-19 disease. © 2022. Nurlela Nurlela et al.

Dual Solution with Heat Transfer through Moving Porous Plate of an Unsteady Incompressible Viscous Fluid

We examine graphically the behavior of the dual solution of an unsteady incompressible viscous flow with heat transfer due to a moving porous surface. The mathematical model is developed with the implementation of conservation laws which are then tackled numerically, and the simulations are performed through the Keller–Box technique. Application of the Keller–Box technique allows the non-linear differential equations to transform to a scheme of linear differential equations which are easier to illuminate. Outcomes of velocity and thermal behavior are shown graphically for certain values of the dimensionless parameters. It is obvious from the results that temperature of fluid decreases with the increasing values of dimensionless Prandtl number Pr, whereas the velocity enhances for blowing situations.
Realistic 3D Modeling and Virtual Fitting Room

—Most of the previously proposed image processing methods have failed to accurately model the human body real-istically, especially, when it comes to 3D modeling of the whole human body, requiring large amount of data and calculations, which is, mainly, due to their lack of competence to take the simultaneous variations in the body surface into account properly. Besides, the foregoing techniques, mostly, do not render realistic movement representations in real-time. This project intends to overcome the aforementioned shortcomings so as to satisfy the requirements of a virtual ﬁtting room. The proposed methodology consists in scanning and performing some analysis on both the user’s body and the prospective garment to be virtually ﬁtted, modeling, extracting measurements and assigning reference points on them and segmenting the 3D visual data imported from the mannequins, and ﬁnally, superimposing, adopting and depicting the resulting garment model on the user’s body.
Optimal transportation between hypersurfaces bounding some strictly convex domains

Let $M,N$ be two smooth compact hypersurfaces of $\R^n$ which bound strictly convex domains equipped with two absolutely continuous measures $\mu$ and $\nu$ (with respect to the volume measures of $M$ and $N$). We consider the optimal transportation from $\mu$ to $\nu$ for the quadratic cost. Let $(\phi:m \to \R,\psi:N \to \R)$ be some functions which achieve the supremum in the Kantorovich formulation of the problem and which satisfy $$ \psi (y) = \inf_{z\in M} \Bigl( \frac{1}{2}|y-z|^2 -\varphi(z)\Bigr); \\ \varphi (x)=\inf_{z\in N} \Bigl( \frac{1}{2}|x-z|^2 -\psi(z)\Bigr). $$ Define for $y \in N$, $$\varphi^\Box(y) = \sup_{z\in M} \Bigl( \frac{1}{2}|y-z|^2 -\varphi(z)\Bigr). $$ In this short paper, we exhibit a relationship between the regularity of $\varphi^\Box$ and the existence of a solution to the Monge problem.
Quantum Probability ― Quantum Logic

On examine le concept de «correlation» et en particulier la correlation des evenements. On etudie des polytopes de correlation classique en termes de sommets et facettes et leur relation avec la logique proportionnelle et la science du calcul. Les correlations quantiques sont examinees en termes d'inegalites lineaires et des polytopes. On donne des exemples dans lesquels les contraintes classiques sont violees par des frequences quantiques, notamment les violations des inegalites de type Bell dans l'experience d'Einstein-Podolski-Rosen. On montre a travers l'etude de la logique quantique que toute conception realiste de cette derniere implique une violation de la localite. On examine l'approche des variables cachees et on construit des theories des variables cachees locales par extension de la probabilite classique. On examine l'interpretation de la mecanique quantique sur la base de l'analyse des correlations

Study of Clinical and Radiographic Outcomes of Patients With Acute Scaphoid Fractures After Union

Background: There is no clear consensus on the best treatment option for scaphoid fractures. Objectives: In this study, we aim to evaluate the short-term clinical and radiologic outcomes in patients with acute isolated scaphoid fractures treated with surgical or nonsurgical methods. Methods: In a retrospective study, 31 patients with acute isolated scaphoid fracture (Mean±SD age: ‎28.9±9.9 ‎years) treated with open reduction and internal fixation (n=15) or cast immobilization (n=16) methods were included. The fractures were classified according to Herbert & Fishers’ classification system. Clinical outcome measures were the wrist range of motion, pinch strength, and grip strength. Radiographic outcome measures were the lunocapitate angle, scapholunate angle, and ulnar variance. The outcome were compared between the involved and uninvolved hands and between surgical or nonsurgical groups. Results: The majority of fractures were type B2 (n=14). In a Mean±SD follow-up of 15.1±3.2‎‏ months, the mean extension, flexion, pinch, and grip strength of the involved hand averaged 81.3%, 80.7%, 90%, and 87% of the uninvolved hand. Accordingly, clinical outcomes were significantly lower in the involved hand. The scapholunate angle was significantly higher in the involved hand (P=0.002). Clinical and radiographic outcomes were not significantly different between the surgical and nonsurgical groups. Radiographic malalignment was detected in 25 scaphoids. No significant correlation was found between the clinical and radiographic outcomes. Conclusion: After scaphoid fracture union, the decrease in wrist range of motion (extension, flexion) and grip/pinch strength has no correlation with radiographic results.
Knowledge Regarding Ventilator-associated Pneumonia and its Prevention Among Nurses Working at Intensive Care Units of Two Teaching Hospitals in Sri Lanka

Introduction: Ventilator-associated Pneumonia (VAP) is the commonest hospital-acquired infection among mechanically ventilated patients in Intensive Care Units (ICUs). Previous studies on ICU nurses report poor practice on VAP and preventive measures. The study aimed to assess knowledge on VAP and its prevention among ICU nurses from two teaching hospitals in Sri Lanka. Methods: A descriptive cross-sectional study was conducted among 127 nurses from adult ICUs. Data were collected using a pre-tested self-administered questionnaire and analysed using SPSS version 20. Knowledge levels were categorized as good (above 75%), average (50-75%) and poor (below 50%). Results: Overall results showed that 62.2% had average, 33.1% had good, and 4.7% had poor knowledge on VAP and its prevention. The mean knowledge score was 70.15±10.5. Most participants had good knowledge on the meaning of VAP (68.5%), upper respiratory tract functions (84.3%), causative microorganisms (56.7%) and mode of transmission (78.7%). The majority had an average knowledge on standard precautions (48.8%) for VAP and poor knowledge on signs of VAP (52%). Regarding prevention of VAP, most of them had good knowledge on natural preventive mechanisms (92.1%), using of suction catheters (96.9%) and reducing microbial colonization in the oropharynx (93.7%). In contrast, poor knowledge was evident on minimum endotracheal (ET) suction pressure (69.3%), minimum ET cuff pressure (64.6%), early weaning from ventilator (72.4%), and disinfection of ventilator parts (53.5%). Conclusions: Overall knowledge of ICU nurses on VAP and its preventive measures was average. Knowledge deficiencies were identified in preventive strategies in maintaining airways and disinfection.

An Approach for a Web-based Analysis Solution with MUSTANG

—Analytical Information Systems (AIS) are comprehensive solutions for analyzing large data sets. The operation of an AIS usually requires an extensive infrastructure. Moreover, usually only specialist users are capable of performing analyses. In this paper, we present an approach for a web-based analysis solution which can be deployed either in a web-based environment or as an on-premise solution. We strongly emphasize self service capabilities by adding knowledge-based components in the form of an additional metadata layer.
Distinct Roles of Arrestin 1 in Photoreceptors During Drosophila Development*

Background: We investigated both trafficking and function of Arrestin 1 (Arr1) in Drosophila. Results: We show that Arr1 translocates to rhabdomeres to modulate deactivation of phosphorylated rhodopsin in adult photoreceptors, but becomes internalized in pupal photoreceptors. Conclusion: Arr1 plays distinct roles in pupal and adult photoreceptors Significance: Trafficking and function of arrestin may be regulated depending on the physiological context. ABSTRACT Arrestin regulates many facets of G-protein coupled receptors’ signaling. In Drosophila , Arrestin 1 (Arr1) is expressed at a lower level than Arrestin 2 (Arr2), and the role of Arr1 in visual physiology is less understood. Here we generated transgenic flies expressing enhanced green fluorescent protein tagged Arr1 neither inactivation nor
Search for the rare decay of B + → (cid:96) + ν (cid:96) γ with improved hadronic tagging

We present the result of the search for the rare B meson decay of B + → (cid:96) + ν γ with (cid:96) = e , µ . For the search the full data set recorded by the Belle experiment of 711 fb − 1 integrated luminosity near the Υ ( 4S ) resonance is used. Signal candidates are reconstructed for photon energies E γ larger than 1 GeV using a novel multivariate tagging algorithm. The novel algorithm fully reconstructs the second B meson produced in the collision using hadronic modes and was speciﬁcally trained to recognize the signal signature in combination with hadronic tag-side B meson decays. This approach greatly enhances the performance. Background processes that can mimic this signature, mainly charmless semileptonic decays and continuum processes, are suppressed using multivariate methods. The number of signal candidates is determined by analyzing the missing mass squared distribution as inferred from the signal side particles and the kinematic properties of the tag-side B meson. No signiﬁcant excess over the background-only hypothesis is observed and upper limits on the partial branching fraction ∆ B with E γ > 1 GeV individually for electron and muon ﬁnal states as well as for the average branching fraction of both lepton ﬁnal states are reported. We ﬁnd a Bayesian upper limit of ∆ B ( B + → (cid:96) + ν (cid:96) γ ) < 3 . 0 × 10 − 6 at 90% CL and also report an upper limit on the ﬁrst inverse moment of the light-cone distribution amplitude of the B meson of λ B > 0 . 24 GeV at 90% CL.
Metabolic Fate of Nitrosoproline in the Rat1

The metabolism of [L/14C]nitrosoproline and [carboxy/-14C]-nitrosoproline was studied in the rat. In most experiments, less than 1% of the administered radioactivity appeared as radio active CO2 in the expired air, and urinary excretion of radio activity was rapid and almost complete as the unchanged compound, which was the only radioactive component de tected in the urine. The absence of any radioactive urinary components corresponding to proline or its metabolites indi cated that no detectable metabolic denitrosation had occurred. Studies of the disappearance of nitrosoproline from the circu lating plasma indicated an apparent volume of distribution of 52% of the total body weight, suggesting some penetration by the compound into the intracellular space. There was no sig nificantly detectable covalent binding of radioactivity from the labeled nitrosoproline to DMA or RNA of the liver and only an extremely low level of binding to liver protein. Taken with the reported noncarcinogenicity of nitrosoproline in rodents, the above findings suggest that proline may be a suitable nitrosatable substrate for use in tests of endogenous nitrosation re actions in animals and human subjects.
