“TUBERCULOUS THYROIDITIS: A RARE CASE REPORT”
Authors: Kumar Avinash , Kishore Manjari , Sinha Garima , Varma S.K.
Published: June 2021

Tuberculosis of thyroid gland is a rare entity even in countries with high prevalence of tuberculosis. The
diagnosis of extra-pulmonary tuberculosis, especially in the rare sites like thyroid, pancreas, striated
and cardiac muscles is difcult. Thyroid tuberculosis, if at all present, is more commonly associated with either miliary or
disseminated tuberculosis or with contagious involvement from adjacent viscera and vertebral body. Hence, for an accurate
diagnosis of thyroid tuberculosis, pathological examination with demonstration of acid-fast bacilli is important along with a
proper clinico-radiological evaluation.
Herein we report a case of 30-year-old male with swelling on the right side of neck who presented with a “solitary thyroid
nodule” on ultrasound and “colloid” in ne needle aspiration cytology (FNAC) with scattered epithelioid like cells along with
benign follicular epithelial cells. However, no denitive diagnosis could be given on cytology due to pauci-cellularity.
Tuberculous thyroiditis was diagnosed on histopathology since the patient underwent right hemithyroidectomy for right side
solitary nodule. The patient was started on Anti-tubercular therapy (ATT) and had no complications in 6 months follow up
period.
Although rare, thyroid tuberculosis should be kept in mind in differential diagnosis of thyroid nodules, even in patients with no
history and symptoms of TB disease elsewhere specially in TB endemic areas.

Published: June 2021

INTRODUCTION - Traumatic brain injury [TBI] most affects the working population and their earning capacity. The
various sub categories of TBI in terms of clinical features,Glasgow coma scale [GCS] and radiology are well defined.We
have attempted an analysis in terms of long term Glasgow outcome score [GOS] and tried to correlate with the various
factors of TBI.
MATERIALS AND METHODS – All patients of TBI over 12 years and below 60 years and those without other major
trauma were included over a period of about two years. The clinical features, presentation GCS, treatment given, and
outcomes were assessed.The three month GOS was scored for all patients and was used to analyse the the initial data in
its light.
RESULTS – A total of 200 patients were eligible for the study and were included. Of these 159 were males and 41 were
females.The average age was 37.16 years.There was a relatively higher proportion of mild TBI and greater prevalence of
fractures and EDH [extradural hematoma].On analyzing with three month GOS we found that 90.4 % of the patients with
mild TBI had a three month GOS of 5 whereas only 31.9% of patients with moderate or severe TBI had a three month GOS
of 5.
CONCLUSION – The long term GOS is most representative of the extent to which the patient has been able to return to
their pre TBI lives. In our study the three month GOS co related well with the initial GCS. Further prospective data can
elaborate more on the effect of other clinical features and radiology on long term GOS

Published: June 2021

Memory corruption bugs continue to plague low-level systems software generally written in unsafe programming languages. In order to detect and protect against such exploits, many pre- and post-deployment techniques exist. In this position paper, we propose and motivate the need for a hybrid approach for the protection against memory safety vulnerabilities, combining techniques that can identify the presence (and absence) of vulnerabilities pre-deployment with those that can detect and mitigate such vulnerabilities post-deployment. Our hybrid approach involves three layers: hardware runtime protection provided by capability hardware, software runtime protection provided by compiler instrumentation, and static analysis provided by bounded model checking and symbolic execution. The key aspect of the proposed hybrid approach is that the protection offered is greater than the sum of its parts -- the expense of post-deployment runtime checks is reduced via information obtained during pre-deployment analysis. During pre-deployment analysis, static checking can be guided by runtime information.
Detection of Lung Nodules in Chest Radiographs Using Wiener Filter and D-CNN Model
Authors: Zubair Muhammad
Published: June 2021

The automatic and accurate detection of lung tumours or nodules plays a vital role in diagnosing lung cancer. Radiologist have to study multiple chest x-rays to diagnose lung cancer. Since it is a very tedious and time-consuming task, lots of automatic nodule detection and classification techniques based on deep learning have been proposed in recent years. As the previous methods completely rely on deep networks, it increases the computational complexity of the nodule detection process, so in this work, we have proposed a modified wiener filter to remove the adaptive noise from the Chest X-Ray (CXR) images which has not been attempted by any researcher, further to make nodules clearer and contrasting we have enhanced the filtered CXR image by using adaptive histogram equalization (AHE). Later, we have performed classification using the simplified VGG network for Deep Convolutional Neural Network (D-CNN) model to detect and classify the lung nodules from CXR images. As a result, we got an accuracy of 92% in training and 94% on validation, which is then compared with the latest state-of-art works to prove the novelty of our proposed method. The dataset used in our study is taken from the Japan Society of Radiological Technology (JSRT). Finally, we have introduced a Computer Interface (CI) through which the proposed work can be implemented in real-time nodule detection applications in the near future.
Reduced k-points based computationally efficient band structure approach for UTB device simulation
Authors: Solanki Ravi , Mishra Nalin Vilochan , Medury Aditya S
Published: June 2021

The accurate calculation of channel electrostatics
parameters, such as charge density and potential, in ultra-thin body (UTB) devices requires self-consistent solution of the
Poisson’s equation and the full band structure, which is channel
material and thickness dependent. For cubic crystals like silicon,
the semi-empirical sp3d5s* tight-binding (TB) model is preferred
in device simulations, over the density functional theory, to
obtain the full band structure because of being computationally
less intensive and equally accurate. However, the computational
time of the TB model scales non-linearly with the channel
thickness and becomes cumbersome for silicon, beyond 5 nm,
primarily because of the increasing size of the TB hamiltonian
that needs to be solved over the entire k-space, in the irreducible
Brillouin zone. In this work, we precisely identify those k-points
corresponding to the energies close to the band minima, where
the Fermi-Dirac probability significantly affects electrostatics
parameters. This enables us to demonstrate a computationally
efficient approach based on solving the hamiltonian only on those
reduced number of k-points. The rigorous benchmarking of the
channel electrostatics parameters obtained from this approach
is performed with results from accurate full band structure
simulations showing excellent agreement over a wide range of
channel thicknesses, oxide thicknesses, device temperatures and
different channel orientations. By showing that the approach
presented in this work is computationally efficient, besides
being accurate, regardless of the number of atomic layers, we
demonstrate its applicability for simulating UTB devices.

The authors have analyzed medical histories of two patients, treated in health care facilities of Kharkiv region from 2008 to 2020. These patients underwent urgent appendectomy, given the existing clinic of acute appendicitis. Morphological examination of the surgical material allowed us to diagnose adenocarcinoma in one case, and neuroendocrine tumor in combination with endometriosis in the other case. Morphological examination of the surgical material in the first case revealed a moderately differentiated adenocarcinoma and diffuse neutrophilic infiltration in all layers of the appendix, and in the second case – a well-differentiated neuroendocrine tumor (G3), combined with the signs of phlegmonous-ulcerative appendicitis and loci of endometriosis. In both cases, there were no specific for the oncological process anamnestic and clinical-instrumental data, and these tumors were manifested by the clinic of acute appendicitis. Only morphological examination of the surgical material allowed identifying the pathological process. Clinical and morphological analysis of cases from the practice of malignant tumors of the appendix (neuroendocrine tumor and adenocarcinoma) will be useful and interesting for the medical community and should stimulate cancer vigilance in physicians.

It is known that in the center of the Earth the temperature is about 5000 0C and in the direction of the earth's crust it decreases. It is also known that the temperature gradient of the Earth is 3 0C every 100 meters in depth and it is constant throughout the planet. Consequently, the temperature of the Earth's crust is the most beneficial source of heat and energy. It accumulates the energy of the sun and is heated by the focal temperature. In Azerbaijan, at a depth of one meter to 50 meters, the temperature is stable and equal to 5-8 ° C.

Two main traits characterize the Czech agriculture after 1989: decrease of agricultural production connected with the fact that a half of active population has left agriculture and then transformation of holder relations with view to property restitution to persons that lost lands and property in the years of collectivization. The article deals with regional differences in the process of both phenomena and tries to explain them.

Metric properties of the canonical defining pair for determined graphs
Authors: Sapunov Serhii , Senchenko Aleksei , Sereda Oleh
Published: June 2021

The aim of this paper is to study the representation of deterministic graphs (D-graphs) by sets of words over the vertex labels alphabet and to find metric properties of this representation. Vertex-labeled graphs are widely used in various computational processes modeling in programming, robotics, model checking, etc. In such models graphs playing the role of an information environment of single or several mobile agents. Walks of agents on a graph determines the sequence of vertices labels or words in the alphabet of labels. A vertex-labeled graph is said to be D-graph if all vertices in the neighborhood of every its vertex have different labels. For D-graphs in case when the graph as a whole and the initial vertex (i.e. the vertex from which the agent started walking) are known there exists the one-to-one correspondence between the sequence of vertices visited by the agent and the trajectory of its walks on the graph. In case when the D-graph is not known as a whole, agent walks on it can be arranged in such way that an observer obtains information about the structure of the graph sufficient to solve the problems of graph recognizing, finding optimal path between vertices, comparison between current graph and etalon graph etc. This paper specifies the representation of D-graphs by the defining pair of sets of words (the first describes cycles of the graph and the second -- all its vertices of degree 1). This representation is an analogue of the system of defining relations for everywhere defined automata. The structure of the so-called canonical defining pair, which is minimal in terms of the number of words, is also considered. An algorithm for building such pair is developed and described in detail. For D-graphs with a given number of vertices and edges, the exact number of words in the first component of its canonical defining pair and the minimum and maximum attainable bounds for the the number of words in the second component of this pair are obtained. This representation allows us to use new methods and algorithms to solve the problems of analyzing vertex-labeled graphs.
On the solvability of a nonlinear difference boundary value problem in the case of parametric resonance
Authors: Chuiko Sergei , Kalinichenko Yaroslav
Published: June 2021

We construct necessary and sufficient conditions for the existence of solution of seminonlinear boundary value problem for a parametric excitation system of difference equations. The convergent iteration algorithms for the construction of the solutions of the semi-nonlinear boundary value problem for a parametric excitation system difference equations in the critical case have been found. The investigation of periodic and Noetherian boundary-value problems in the critical cases is traditionally performed under the assumption that the differential equation and boundary conditions are known and fixed. As a rule, the study of periodic problems in the case of parametric resonance is reduced to the investigation of the problems of stability. At the same time, due to numerous applications in electronics, geodesy, plasma theory, nonlinear optics, mechanics, and machine-building, the analysis of periodic boundary-value problems in the case of parametric resonance requires not only to find the solutions but also to determine the eigenfunctions of the corresponding differenсе equation. The investigation of autonomous Noetherian boundary-value problems is also reduced to the study of Noetherian boundary-value problems in the case of parametric resonance because the change of the independent variable in the critical case gives a nonautonomous boundary-value problem with an additional unknown quantity. The aim of the present paper is to construct the solutions of Noetherian boundary-value problems in the case of parametric resonance whose solvability is guaranteed by the corresponding choice of the eigenfunction of the analyzed boundary-value problem. The applied classification of Noetherian boundary-value prob\-lems in the case of parametric resonance depending on the simplicity or multiplicity of roots of the equation for generating constants noticeably differs from a similar classification of periodic problems in the case of parametric resonance and corresponds to the general classification of periodic and Noetherian boundary-value problems. The equation for generating constants obtained for the Noetherian boundary-value problems in the case of parametric resonance strongly differs from the conventional equation for generating constants in the absence of parametric resonance by the dependence both of the equation and of its roots on a small parameter, which leads to noticeable corrections of the approximate solutions as compared with the approximations obtained by the Poincare method. Using the convergent iteration algorithms we expand solution of seminonlinear two-point boundary value problem for a parametric excitation Mathieu type difference equation in the neighborhood of the generating solution. Estimates for the value of residual of the solutions of the seminonlinear two-point boundary value problem for a parametric excitation Mathieu type difference equation are found.
Caratheodory theorem about prime ends on Riemann surfaces
Authors: Ryazanov Vladimir , Volkov Serhii
Published: June 2021

The present paper is a continuation of our research that was devoted to the theory of the boundary behavior of mappings on Riemann surfaces. Here we develop the theory of the boundary behavior of the mappings in the class FLD (mappings with finite length distortion) first introduced for the Euclidean spaces in the article of Martio--Ryazanov--Srebro--Yakubov at 2004 and then included in the known monograph of these authors in the modern mapping theory at 2009. As it was shown in the recent papers of Kovtonyuk-Petkov-Ryazanov at 2017, such mappings, generally speaking, are not mappings in the Sobolev classes because their first partial derivatives can be not locally integrable. At the same time, this class is a natural generalization of the well-known significant classes of isometries and quasi--isometries. We obtain here a series of criteria in terms of dilatations for the homeomorphic extension of the mappings with finite length distortion between domains on Riemann surfaces to the completions of the domains by prime ends of Caratheodory. Here we start from the general criterion in Lemma 1 in terms of singular functional parameters and then derive on this basis many other criteria. In particular, Lemma 1 implies Theorem 1 with a criterion of the Lehto type and Corollary 1 shows that the
conclusion holds, if the dilatation grows not quickly than logarithm of the hyperbolic distance at every boundary point. The next consequence in Theorem 2 gives an integral criterion of the Orlicz type and Corollary 2 says on simple integral conditions of the exponential type. Further, Theorem 3 and Remark 2 contain criteria in terms of singular integrals of the Calderon--Zygmund type. The other criterion in Theorem 4 is the existence of a dominant for the dilatation in the class FMO (functions with finite mean
oscillation), i.e., having a finite mean deviation from its mean value over infinitesimal discs centered at boundary points. In other words, the latter means that such a dominant has a finite dispersion over the given infinitesimal discs. In particular, the latter leads to Corollary 3 on a dominant in the well--known class BMO (bounded mean oscillation) by John--Nirenberg and to a simple criterion in Corollary 4 on finiteness of the average of the dilatation over infinitesimal disks centered at boundary points.
Minimal Deterministic Traversable Vertex Labelling of Infinite Square Grid Graph
Authors: Sapunov Serhii
Published: June 2021

Automata walking on graphs are a mathematical formalization of autonomous mobile agents with limited memory operating in discrete environments. Under this model a broad area of studies of the behaviour of automata in labyrinths arose and intensively developing last decades
(a labyrinth is an embedded directed graph of special form). Research in this regard received a wide range of applications, for example, in the problems of image analysis and navigation of mobile robots. Automata operating in labyrinths can distinguish directions, that is, they have a compass. This paper deals with the problem of constructing square grid graph vertex labelling thanks to which a finite automaton without a compass can walk on graph in any arbitrary direction. The automaton looking over neighbourhood of the current vertex and may travel to some neighbouring vertex selected by its label. In this paper, we propose a minimal deterministic traversable vertex labelling that satisfies the required property. A labelling is said to be deterministic if all vertices in closed neighbourhood of every vertex have different labels. In previous works we have proved that minimal deterministic traversable vertex labelling of square grid graph uses labels of five different types. In this paper we prove that a collective of one automaton and three pebbles can construct this labelling on initially unlabelled infinite square grid graph. We consider pebbles as automata of the simplest form, whose positions are completely determined by the remaining automata of the collective.
Energetic effects analysis of shear waves and their second harmonics in a waveguide with non-ideal component contact
Authors: Zhogoleva Nadiia
Published: June 2021

In this article the energetic and kinematic effects that occur in the elastic shear wave and its second harmonics propagation are investigated. The waveguide consists of anisotropic elastic crystal layer of cubic system m3m class enclosed between crystal halfspaces of same anisotropy class. A slipping contact is assumed in the contact zone of waveguide parts. The research is based on a model of general geometrical end physical nonlinearity in dynamic deformation processes. It allows to use elastic potential with the quadratic and cubic deformation components and the deformations with nonlinear terms. The approach of nonlinear elastic wave characteristics expansion into rows of a small parameter is used. Due to this approach at the first stage it's necessary to solve the problem of finding the components of the localized shear wave displacement vector (the problem of the first approximation). In the second stage, using the obtained results of the first approximation problem, the representation of the components of the displacement vector for the second harmonics of the localized elastic wave is solved in analytical form (the problem of the second approximation). By using the obtained kinematic results, the energy effects can be evaluated in the form of a vector of the average for the period of power flow. Specific results of the study of the amplitude-frequency and energy characteristics of the localized shear type elastic waves in the considered waveguide structure were obtained using computer algebra methods.The calculations of cinematic and energetic characteristics (that in contrast to linear SH harmonic are P-SV type waves) have been carried out for NaCl layer and germanium halfspaces waveguide.
