Etiological profile, prescribing pattern of antibiotics and clinical outcomes of pneumonia patients in a tertiary care hospital in South India during 5-year period
Authors: Mathew Jerrin Reji , Noyal Shiyona , Biju Sijin T. , Joseph Siby , Jose Amit P.
Published: December 2022

Background:

Pneumonia is one of the most important and serious lower respiratory tract infections, which requires implacable attention. This work aimed to document the causative organisms, antibiotics used, and outcome of pneumonia patients hospitalized in a tertiary care hospital.

Materials and Methods:

A retrospective study was conducted in the medical departments of a tertiary care teaching hospital for 5 years. Demographic details and clinical details including pertinent laboratory values of patients diagnosed with pneumonia were documented and analyzed using a specifically designed data collection form.

Results:

The study was conducted on 190 patients. The average age of the study population was 56.7 ± 22.6 years and there was a male preponderance of 111(58.4%) patients. Klebsiella pneumonia was found to be the most frequently isolated pathogen in 12.5% of the sputum culture, followed by Acinetobacter baumannii in 10.22% and Pseudomonas aeruginosa in 9.09%. The most commonly prescribed empirical antibiotics were beta-lactam antibiotics mostly in combination with macrolides for synergy irrespective of Pneumonia Severity Index (PSI) classes. Definitive therapy was classified based on World Health Organization (WHO) Access, Watch, and Reserve (AWaRe) classification of antibiotics, watch category antibiotics were prescribed according to culture report and reserve antibiotics were prescribed only in those cases where watch category antibiotics were resistant. On analyzing PSI of community-acquired pneumonia (176 patients), most of the patients in the study belong to class 4: 61 patients (34.7%) and class 5: 44 patients (25%). For the high-risk patients (PSI class 4 and 5), mortality was approximately 3.8% (4 of 105) and for low-risk patients, there was zero mortality reported within 30 days.

Conclusion:

Gram-negative bacteria were the major pathogens causing Pneumonia in the study site contradictory to the data from developed countries. Identifications of pathogens and appropriate antibiotic therapy based on PSI score can bring down the duration of hospital stay and mortality of patients with pneumonia.
Primary assessment of patients admitted to the emergency ward using arterial blood gas
Authors: Mulay Sanjay , Ursekar Rajesh , Mathew Jerry , Pinto Krista
Published: December 2022

Background:

Arterial blood gas study (ABG) is a point-of-care testing (POCT) diagnostic tool that can furnish metabolic and respiratory aberrations. This study was conducted systematically, to assess the metabolic and respiratory aberrations quickly and the scope for corrective treatment so that metabolic and respiratory abnormalities get corrected.

Materials and Methods:

A prospective cross-sectional study was done among 150 cases admitted to the Department of Emergency Medicine during a three-month period where the study on ABG was done. Data was collected in the prescribed format and a stepwise interpretation of the ABG was done. The four primary disorders taken into consideration are metabolic acidosis, metabolic alkalosis, respiratory alkalosis, and respiratory acidosis

Results:

Out of 150 cases 82 had respiratory alkalosis, 51 had metabolic acidosis, ten had respiratory acidosis, and seven had metabolic alkalosis as a primary disorder.

Conclusion:

ABG analysis is a POCT diagnostic tool for analyzing various metabolic and respiratory aberrations and can also guide us in the scope for correction of the disorder.
A comparative assessment of the level of stockouts of modern family planning services in private and public health facilities in Nigeria
Authors: Onoja Ali J. , Sanni Felix O. , Onoja Sheila I. , Abu Aisha
Published: December 2022

Background:

The use of family planning (FP) methods and stockouts of contraceptives are major challenges to the FP program in Sub-Saharan Africa. This study assessed the level of stockouts of contraceptives in Nigerian health facilities. This survey was carried out in 767 health facilities offering FP services across all six geopolitical zones of Nigeria.

Materials and Methods:

This was a cross-sectional study involving a quantitative technique. Data were collected from 116 private and 651 public health facilities in Nigeria. A structured questionnaire was used to collect data from the facilities, and a physical inventory was taken. Data were analyzed using IBM-SPSS, version 25.0.

Results:

The stockout rate in the last 3 months was 63.8% in private and 47.5% in public health facilities (P = 0.001), whereas stockouts on the visit day were 63.8% in private and 51.0% in public facilities (P = 0.011). On the day of the visit, the stockout rate in private health facilities ranged from 9.3% to 26.5%, whereas it ranged from 5.3% to 24.2% in public health facilities. The main causes of stockouts of some contraceptives are low/no demand and a lack of supply.

Conclusions:

This study found a high level of stockouts of FP services in private and public health facilities, but higher in private facilities. Both the poor supply and low demand for FP services in Nigeria require the attention of policymakers and health officials.
Abdominal oocyte pickup in patient with uterine factor infertility
Authors: Gopinath P. M. , Manoharan Sahityalakshmi
Published: December 2022

During infertility treatment, ultrasound was required for both diagnostic and therapeutic procedures. Transvaginal route of oocyte retrieval was preferred due to its better visualization, easy accessibility, decreased intestinal trauma, and high pickup rate. Here we have a rare case scenario where abdominal oocyte retrieval was done in a patient with fibroid uterus due to the inaccessibility of both ovaries by the transvaginal method.
Sequential and distributive forcings without choice
Authors: Karagila Asaf , Schilhan Jonathan
Published: December 2022

In the Zermelo–Fraenkel set theory with the Axiom of Choice, a forcing notion is “
$\kappa $
-distributive” if and only if it is “
$\kappa $
-sequential.” We show that without the Axiom of Choice, this equivalence fails, even if we include a weak form of the Axiom of Choice, the Principle of Dependent Choice for
$\kappa $
. Still, the equivalence may still hold along with very strong failures of the Axiom of Choice, assuming the consistency of large cardinal axioms. We also prove that although a
$\kappa $
-distributive forcing notion may violate Dependent Choice, it must preserve the Axiom of Choice for families of size 
$\kappa $
. On the other hand, a
$\kappa $
-sequential can violate the Axiom of Choice for countable families. We also provide a condition of “quasiproperness” which is sufficient for the preservation of Dependent Choice, and is also necessary if the forcing notion is sequential.
Hepp’s bound for Feynman graphs and matroids
Authors: Panzer Erik
Published: December 2022

We study a rational matroid invariant, obtained as the tropicalization of the Feynman period integral. It equals the volume of the polar of the matroid polytope and we give efficient formulas for its computation. This invariant is proven to respect all known identities of Feynman integrals for graphs. We observe a strong correlation between the tropical and transcendental integrals, which yields a method to approximate unknown Feynman periods.
Classifying compact 4-manifolds via generalized regular genus and G-degree
Authors: Casali Maria Rita , Cristofori Paola
Published: December 2022

(d+1)

-
colored graphs
, i.e., edge-colored graphs that are

(d+1)

-regular, have already been proved to be a useful representation tool for compact PL

d

-manifolds, thus extending the theory (known as
crystallization theory
) originally developed for the closed case. In this context, combinatorially defined PL invariants play a relevant role. The present paper focuses in particular on
generalized regular genus
and
G-degree
: the first one extending to higher dimension the classical notion of Heegaard genus for 3-manifolds, the second one arising, within theoretical physics, from the theory of random tensors as an approach to quantum gravity in dimension greater than two. We establish several general results concerning the two invariants, in relation with invariants of the boundary and with the rank of the fundamental group, as well as their behaviour with respect to connected sums. We also compute both generalized regular genus and G-degree for interesting classes of compact

d

-manifolds, such as handlebodies, products of closed manifolds by the interval and

\mathbb D^2

-bundles over

\mathbb S^2.

The main results of the paper concern dimension 4, where we obtain the classification of all compact PL manifolds with generalized regular genus at most one, and of all compact PL manifolds with G-degree at most 18; moreover, in case of empty or connected boundary, the classifications are extended to generalized regular genus two and to G-degree 24.
Apéry-like numbers for non-commutative harmonic oscillators and automorphic integrals
Authors: Kimoto Kazufumi , Wakayama Masato
Published: December 2022

The purpose of the present paper is to study the number theoretic properties of the special values of the spectral zeta functions of the non-commutative harmonic oscillator (NcHO), especially in relation to modular forms and elliptic curves from the viewpoint of Fuchsian differential equations, and deepen the understanding of the spectrum of the NcHO. We study first the general expression of special values of the spectral zeta function

\zeta_Q(s)

of the NcHO at

s=n

(n=2,3,\dots)

and then the generating and meta-generating functions for
Apéry-like numbers
defined through the analysis of special values

\zeta_Q(n)

. Actually, we show that the generating function

w_{2n}

of such Apéry-like numbers appearing (as the “first anomaly”) in

\zeta_Q(2n)

for

n=2

gives an example of
automorphic integral with rational period functions
in the sense of Knopp, but still a better explanation remains to be clarified explicitly for

n>2

. This is a generalization of our earlier result on showing that

w_2

is interpreted as a

\Gamma(2)

-modular form of weight

1

. Moreover, certain congruence relations over primes for “normalized” Apéry-like numbers are also proven. In order to describe

w_{2n}

in a similar manner as

w_2

, we introduce a
differential Eisenstein series
by using analytic continuation of a classical generalized Eisenstein series due to Berndt. The differential Eisenstein series is actually a typical example of the automorphic integral of negative weight. We then have an explicit expression of

w_4

in terms of the differential Eisenstein series. We discuss also shortly the Hecke operators acting on such automorphic integrals and relating Eichler’s cohomology group.
Topological quantum field theory and polynomial identities for graphs on the torus
Authors: Fendley Paul , Krushkal Vyacheslav

We establish a relation between the trace evaluation in SO(3) topological quantum field theory and evaluations of a topological Tutte polynomial. As an application, a generalization of the Tutte golden identity is proved for graphs on the torus.
Lozenge tilings of hexagons with removed core and satellites
Authors: Ciucu Mihai , Fischer Ilse
Published: December 2022

We consider regions obtained from 120 degree rotationally invariant hexagons by removing a core and three equal satellites (all equilateral triangles) so that the resulting region is both vertically symmetric and 120 degree rotationally invariant, and give simple product formulas for the number of their lozenge tilings. We describe a new method of approach for proving these formulas, and give the full details for an illustrative special case. As a byproduct, we are also able to generalize this special case in a different direction, by finding a natural counterpart of a twenty year old formula due to Ciucu, Eisenkölbl, Krattenthaler, and Zare, which went unnoticed until now. The general case of the original problem will be treated in a subsequent paper. We then work out consequences for the correlation of holes, which were the original motivation for this study.
A study in $\mathbb{G}_{\mathbb{R}, \geq 0}(2,6)$: from the geometric case book of Wilson loop diagrams and SYM $N=4$
Authors: Agarwala Susama , Fryer Siân Zee
Published: December 2022

We study the geometry underlying the Wilson loop diagram approach to calculating scattering amplitudes in Supersymmetric Yang Mills (SYM)

N=4

. In particular, we study the smallest non-trivial multi-propagator case, consisting of 2 propagators on 6 vertices. We do this by translating the integrals of the theory to the combinatorics of the positive geometry each diagram represents, specifically identifying the positroid cells defined by each diagram and the homology of the subcomplex they collectively generate in

\mathbb{G}_{\mathbb{R}, \geq 0}(2,6)

. We verify the conjecture that the spurious singularities of the volume functional
do
all cancel on the codimension 1 boundaries of these cells, in this case. We also show that how the spurious singularities cancel is actually much more complicated than previously understood. The direct calculation laid out in this paper identifies many intricacies and artifacts of the geometry of Wilson loop diagram that need further study.
Homological norms on nonpositively curved manifolds
Authors: Connell Chris , Wang Shi
Published: December 2022

We relate the Gromov norm on homology classes to the harmonic norm on the dual cohomology and obtain double sided bounds in terms of the volume and other geometric quantities of the underlying manifold. Along the way, we provide comparisons to other related norms and quantities as well.
Almost finiteness and homology of certain non-free actions
Authors: Ortega Eduard , Scarparo Eduardo
Published: December 2022

We show that Cantor minimal

\mathbb{Z}\rtimes\mathbb{Z}_2

-systems and essentially free amenable odometers are almost finite. We also compute the homology groups of Cantor minimal

\mathbb{Z}\rtimes\mathbb{Z}_2

-systems and show that the associated transformation groupoids satisfy the HK conjecture if and only if the action is free.
Secondary higher invariants and cyclic cohomology for groups of polynomial growth
Authors: John Sheagan
Published: December 2022

We prove that if

\Gamma

is a group of polynomial growth, then each delocalized cyclic cocycle on the group algebra has a representative of polynomial growth. For each delocalized cocycle, we thus define a higher analogue of Lott’s delocalized eta invariant and prove its convergence for invertible differential operators. We also use a determinant map construction of Xie and Yu to prove that if

\Gamma

is of polynomial growth, then there is a well-defined pairing between delocalized cyclic cocycles and

K

-theory classes of

C^*

-algebraic secondary higher invariants. When this

K

-theory class is that of a higher rho invariant of an invertible differential operator, we show this pairing is precisely the aforementioned higher analogue of Lott’s delocalized eta invariant. As an application of this equivalence, we provide a delocalized higher Atiyah–Patodi–Singer index theorem, given that

M

is a compact spin manifold with boundary, equipped with a positive scalar metric

g

and having fundamental group

\Gamma=\pi_1(M)

which is finitely generated and of polynomial growth.
Purely infinite corona algebras and extensions

\mathbf{Ext}(C(X), \mathcal{B}) \rightarrow KK(C(X), \mathcal{M}(\mathcal{B})/\mathcal{B}).
Deconvolution for some singular density errors via a combinatorial median of means approach
Authors: Marteau Clément , Sart Mathieu
Published: December 2022

We present a versatile and model based procedure for estimating a density in a deconvolution setting where the error density is assumed to be singular enough.We assess the quality of our estimator by establishing non-asymptotic risk bounds for the

\mathbb{L}^1

loss. We specify them when the density is piecewise constant on a finite number of (unknown) pieces, when it is unimodal, and when it is concave/convex.
Perturbative techniques in conformal geometry
Authors: Malchiodi Andrea
Published: December 2022

This paper reviews some results, mostly perturbative in nature, concerning the prescription of scalar curvature via conformal deformation of the metric on a compact manifold. This problem consists in solving a nonlinear elliptic equation with critical power, leading to non-compactness phenomena. We will see how some finite-dimensional reduction of the problem in certain situations, jointly with the variational structure, can help in finding existence and multiplicity results.

case.
Min-max levels transition in parametrized elliptic problems on unbounded domains
Authors: Devillanova Giuseppe , Solimini Sergio
Published: December 2022

We discuss some attempts to apply the classical variational methods, in the spirit of Ambrosetti–Rabinowitz, to parametrized elliptic problems defined on unbounded domains. We construct some min-max classes and establish some estimates which allow, for instance, to conclude that, while for a generic coefficient there is always a solution for all small values of the parameter, in the case of a coefficient with a suitable exponential decay and in dimension

N=2

the set of the values of the parameter for which the problem has a nontrivial solution is unbounded.
Internal mode-induced growth in $3$d nonlinear Klein–Gordon equations
Authors: Léger Tristan , Pusateri Fabio
Published: December 2022

This note complements the paper [arXiv:2112.13163] by proving a scattering statement for solutions of nonlinear Klein–Gordon equations with an internal mode in 3d. We show that small solutions exhibit growth around a one-dimensional set in frequency space and become of order one in

L^\infty

after a short transient time. The dynamics are driven by the feedback of the internal mode into the equation for the field (continuous spectral) component.

The main part of the proof consists of showing suitable smallness for a “good” component of the radiation field. This is done in two steps: first, using the machinery developed in [arXiv:2112.13163], we reduce the problem to bounding a certain quadratic normal form correction. Then we control this latter by establishing some refined estimates for bilinear operators with singular kernels.

Обсуждается точно решаемая релятивистская модель нерелятивистского линейного гармонического осциллятора при наличии постоянной внешней силы. Показано, что, как и в нерелятивистском случае, релятивистский линейный осциллятор во внешнем однородном поле унитарно эквивалентен релятивистскому линейному осциллятору без этого поля. Вычислены двумя способами амплитуды переходов между энергетическими состояниями дискретного спектра релятивистского линейного осциллятора под действием внезапно налагаемого однородного поля. Найдены когерентные состояния Барута-Жирарделло и функция Грина в координатном и импульсном представлениях. Получены линейная и билинейная производящие функции для полиномов Мейкснера-Поллачека. Доказано, что релятивистские волновые функции, генераторы динамической группы симметрии и амплитуды переходов имеют правильный нерелятивистский предел.
Long range‐based low‐power wireless sensor node
Authors: Devi Komal , Mahajan Rita , Bagai Deepak
Published: December 2022

Sensor nodes are the most significant part of a wireless sensor network that offers a powerful combination of sensing, processing, and communication. One major challenge while designing a sensor node is power consumption, as sensor nodes are generally battery‐operated. In this study, we proposed the design of a low‐power, long range‐based wireless sensor node with flexibility, a compact size, and energy efficiency. Furthermore, we improved power performance by adopting an efficient hardware design and proper component selection. The Nano Power Timer Integrated Circuit is used for power management, as it consumes nanoamps of current, resulting in improved battery life. The proposed design achieves an off‐time current of 38.17309 nA, which is tiny compared with the design discussed in the existing literature. Battery life is estimated for spreading factors (SFs), ranging from SF7 to SF12. The achieved battery life is 2.54 years for SF12 and 3.94 years for SF7. We present the analysis of current consumption and battery life. Sensor data, received signal strength indicator, and signal‐to‐noise ratio are visualized using the ThingSpeak network.
Optimum solar energy harvesting system using artificial intelligence
Authors: Sangsang Sasmowiyono Sunardi , Fadlil Abdul , Subrata Arsyad Cahya
Published: December 2022

Renewable energy is promoted massively to overcome problems that fossil fuel power plants generate. One popular renewable energy type that offers easy installation is a photovoltaic (PV) system. However, the energy harvested through a PV system is not optimal because influenced by exposure to solar irradiance in the PV module, which is constantly changing caused by weather. The maximum power point tracking (MPPT) technique was developed to maximize the energy potential harvested from the PV system. This paper presents the MPPT technique, which is operated on a new high‐gain voltage DC/DC converter that has never been tested before for the MPPT technique in PV systems. Fuzzy logic (FL) was used to operate the MPPT technique on the converter. Conventional and adaptive perturb and observe (P&O) techniques based on variables step size were also used to operate the MPPT. The performance generated by the FL algorithm outperformed conventional and variable step‐size P&O. It is evident that the oscillation caused by the FL algorithm is more petite than variables step‐size and conventional P&O. Furthermore, FL's tracking speed algorithm for tracking MPP is twice as fast as conventional P&O.
The End of the Earliest Ceramic Traditions
Authors: Mazurkevich Andrey , Dolbunova Ekaterina , Maigrot Yolaine , Filippova Veronika
Published: December 2022

The Dnieper-Dvina area is one of the regions in Eastern Europe which was part of a wider network of the earliest ceramic traditions, spread in the first half to the middle of the 6th millennium BC. After the collapse of this network new ceramic complexes appeared here, called the Rudnya culture, and at the end of the 6th millennium BC this manifested in changes in the directions of cultural connections. This region became part of the cultural space of the Circum-Baltic area. Several complexes within the Rudnya culture originated in different groups of Narva pottery, and are dated to c. 5400–4400 cal BC.
What We Do for Food
Authors: Đuričić Ana
Published: December 2022

Food is essential for survival, but how humans obtain and manage it is regulated socially. The life of Neolithic and other non-industrial communities depended on environmental variations – temperature patterns and precipitation. For farming communities, even minor changes in those patterns could have led to periods of food scarcity. In order to overcome and prepare for periods of scarcity, non-industrial communities applied different social buffering strategies. In this paper, the social buffering strategies Early/Middle Neolithic Starčevo and Late Neolithic Vinča culture communities applied in overcoming the environmental variability are tested and the most plausible ones are considered.
Evangelism and election: Is there an answer to the challenges?
Authors: Verster Pieter
Published: December 2022

It is always a challenge to review the relation between evangelism and election. Biblical views are essential. Important exponents of evangelism such as Bosch, Bevans and Schroeder, Christopher Wright, and Kirk are presented, but also the challenging view of Tutu. Especially Bosch’s comprehensive view of evangelism is important. He explains that evangelism is not presenting the gospel to those in need to hear it again after rejecting it, but presenting the gospel of salvation to all. Calvin’s view on election is always extremely important because of his views on election and rejection. He explains his view that God elects in freedom in Christ because He is the living God and that He has the right to reject those who are not in Christ because of their sins. Ephesians
1 and Romans 9 call for intensive scrutiny in this regard. Election is always in Christ, and one should emphasise the mercy and love of God. Evangelism and election go together, for both proclaim the glory of God in his love. The call to come and convert to God in evangelism is essential for the church. Election and evangelism are about the love of God in Christ, the crucified and resurrected one. Therefore, the missional church should always proclaim new life in Christ in the future in God’s mercy and love. Election and evangelism are not mutually exclusive but call for radically honouring the living God in his total redemption of humankind.

Published: December 2022

The purpose of this study was to determine the form of parental involvement in children's households in the Guraping Village, North Oba District, Tidore Islands City. The results of the study describe the habits of parents who do not understand their position in the midst of children's family life so that parents are not the arbiters between their children's disputes as husband and wife, but as unilateral decision- making that harms life between husband and wife in this case their children. The conclusion from this study is that parental involvement in children's households does not always have a positive impact on their children. In Islamic law the involvement of parents in a child's household is permissible as long as it does not contain elements of tyranny, mediating between children's disputes is not based on reasons of economic conflict. Parents must be a source of solutions for both.
The History of the Reformation of the Church in the 16th Century and Its Influence on the Church Today
Authors: Sutri Yerlin Vinni , Putrawan Bobby Kurnia
Published: December 2022

The history of the reformation of the church is a very long and very memorable history for the church. The Reformation was an attempt by the reformers to return the church to biblical authority. The life of the church before the reformation was very far from the truth of the Bible, where church leaders carried out deviations and heretical teachings. Many church leaders take advantage of their position to gain profit, for example the sale of a pardon. Luther invited people at that time to turn to the true teachings of the Bible. Outside of Martin Luther, there were also reformers who continued Luther's work, namely John Calvin and Ulrich Zwingli. After 500 years of church reformation, the church today is still feeling the effects of the reformation although there are still churches that deviate from the teachings of the Bible. The church reformation changed wrong mindsets and views and brought believers to the true truth of the Bible. The results of the reformation brought believers to the true knowledge of Jesus Christ. The situation before the reformation and after the reformation is very different, where the entire leadership in the church has been changed. Leaders in the church today are not only governed by the pastor but also by people who have been chosen and determined.

Pembahasan ini lebih membahas tentang kanon kristen pada jaman dulu. Hal ini menyebabkan nilai-nilai dan pesan moral sebagai substansi dasar dalam sastra cenderung dianggap dan sikapi sebagai acuan standart ideal perilaku manusia dalam kehidupannya sebagai makhluk individual dan sosial, bukan sebagai makhluk biologis, lebih-lebih sebagai makhluk ekologis. Wacana etika sering kali menjelaskan tujuan dari penglihatan bagi para pembaca. Simbolisme esoterik merupakan sifat yang paling tampak dari sastra apokalipsis. Pada pembahasan apokaliptik selalu melibatkan hermeneuetik. Oleh akrna itu hermeneuetik menjadi acuan dalam pembahasan analisis apokaliptik, dan tidak biasa di lepas dari situ. Oleh karna itu, hermeneuetik juga harus dipahami secara dasar. . Pada tulisan ini menggunakan metodologi kualitatif, dimana sumber-sumber dari pustaka menjadi acua.  Kita juga tahu bahwa pmbelajaran apokaliptik ini sendiri sangat sulit di buat batasannya. Karena apokaliptik ini pada umumnya digunakan dalam kata benda. Jadi sering sekali analisi ini tidak digunakan dalam penganalisisan.
Koje karakteristike tkiva vidimo na rendgenskoj slici?
Authors: Pašić Selim , Klobučar Antea
Published: December 2022

Cilj je ovoga rada povezivanje temeljnih karakteristika tkiva s rezultatima dobivenim na rendgenskoj slici, analizirajući fizikalne principe interakcije koje vode do atenuacije rendgenskih fotona u tkivu. Na slikovitom primjeru dokazujemo da nećemo moći imati superdijagnostički uređaj koji bi mogao zamijeniti sve moderne i buduće dijagnostičke uređaje. Svakase tehnika oslikavanja tkiva temelji na jedinstvenim fizikalnim principima te stoga ona vidi točno određene kakateristike tkiva koja drugi dijagnostički uređaji (tehnike) ne mogu vidjeti. Oslikavanje se rendgenskim uređajem temelji na atenuaciji (slabljenju) snopa rendgenskih zraka nakon prolaska kroz tkivo. Glavni su mehanizmi interakcije rendgenskih fotona i tkiva fotoelektrični efekt (potpuna apsorpcija energije fotona) te Comptonovo raspršenje (djelomična apsorpcija energije fotona). Fotoelektrični efekt dominira na niskim i djelomično srednjim energijama i s povećanjem energije jako slabi, dok na srednjim i višim energijama dominira Comptonovo raspršenje. Analizom oba raspršenja, nakon dekompozicije linearnoga koeficijenta atenuacije na uobičajene fizikalne veličine, nalazimo da u režimu Comptonovoga raspršenja kontrast na slici je određen razlikama u gustoći tkiva, a u režimu fotoelektričnoga efekta ovisi o gustoći tkiva te snažno o rednom broju elemenata od kojih je tkivo sastavljeno. U radu su grafički prikazane vrijednosti kontrasta na rendgenskoj slici za osnovne tvorbe i tkiva i opisane njihove karakteristike, gustoća i redni broj elemenata od kojih su sastavljeni. Kompjuterizirana tomografija (CT) vidi potpuno iste karakteristike tkiva kao i klasična rendgenska tehnika. U radu je na eksplicitnom dvodimenzionalnom primjeru objašnjen princip komjuterizirane tomografije. On se temelji na zamišljenoj podjeli tkiva na male volumene (voksele) i snimanju tkiva iz više pozicija, pri čemu se za svaku poziciju postavljaju jednadžbe za apsorpciju zračenja. U dobivenom sustavu jednadžbi nepoznate vrijednosti su vrijednosti linearnog koeficijenta atenuacije za svaki voksel, koje se odrede numeričkim rješavanjem sustava jednadžbi, i prikažu na prikladnoj skali boja u trodimenzionalnom prikazu.

Published: December 2022

Pets living in urban agglomerations are subject to numerous risk factors that provoke health problems. One of these factors is a violation of the “wakefulness-sleep” cycle. A sleep-deprived animal is in a state of serious stress, since this condition is more difficult to tolerate than food deprivation, making the animal more susceptible to health decline factors. Due to this problem, sleep hygiene plays an important role in ensuring the wellfare of pet dogs. The article provides an overview of modern studies on the specificities of the sleep-wake cycles in domestic dog (Canis lupus familiaris L.). Modern data on the general physiology of mammal sleep, especially pet dogs, are examined. Methods to analyses the features of the sleep cycles of dogs and their possible disorders are given. Also, we discuss the influence of co-sleeping of a person and a dog on the quality of sleep of both.
On the biased Two-Parameter Estimator to Combat Multicollinearity in Linear Regression Model
Authors: Idowu Janet Iyabo , Oladapo Olasunkanmi James , Owolabi Abiola Timothy , Ayinde Kayode
Published: December 2022

The most popularly used estimator to estimate the regression parameters in the linear regression model is the ordinary least-squares (OLS). The existence of multicollinearity in the model renders OLS inefficient. To overcome the multicollinearity problem, a new two-parameter estimator, a biased two-parameter (BTP), is proposed as an alternative to the OLS. Theoretical comparisons and simulation studies were carried out. The theoretical comparison and simulation studies show that the proposed estimator dominated some existing estimators using the mean square error (MSE) criterion. Furthermore, the real-life data bolster both the hypothetical and simulation results. The proposed estimator is preferred to OLS and other existing estimators when multicollinearity is present in the model.

Despite its common usage in estimating the linear regression model parameters, the ordinary least squares estimator often suffers a breakdown when two or more predictor variables are strongly correlated. This study proposes an alternative estimator to the OLS and other existing ridge-type estimators to tackle the problem of correlated regressors (multicollinearity). The properties of the proposed estimator were derived, and six forms of biasing parameter k (generalized, median, mid-range, arithmetic, harmonic and geometric means) were used in the proposed estimator to compare its performance with five other existing estimators through a simulation study. The proposed estimator dominated existing estimators when the mid-range, arithmetic mean, and median versions of k were used. However, the proposed estimator did not perform well when the generalized, harmonic, and geometricmean versions were used.

Published: December 2022

This paper aims to evaluate how the participation companies perform in Turkey during the period of 2016 to 2020. The study uses daily returns for evaluating performance for portfolios and companies. The evidence from the returns of 102 companies, consists of 1256 observations. The study adopts the CAPM extended to Fama and French model to evaluate six portfolios of companies and denoted that all portfolios from participation companies show better performance than the market during the period under review. It shows that the larger the size and value of the portfolio, or the smaller the size and value, the more efficient the performance is. Besides, the results show that most companies outperformed the market benchmark. This study contributes to analyzing performance of hundred and two types of participation companies, that are relevant and important for Turkish and foreign investments.
SİSTEM TEORİSİ ve YENİ SİSTEMİN POLİTİKA KURULLARI
Authors: BİLGİN Hande
Published: December 2022

Klasik ve Neo-klasik Yönetim Düşüncesi, örgütlerin yönetilmesinde mekanik bir evren modeli ve geleneksel tersinebilir anlayışı benimsemektedir. Bu anlayış, örgütleri statik ve kapalı sistemler olarak tanımlamaktadır. Bilgi teknolojilerindeki değişimler, örgütleri statik bir nesneden performatif bir sürece dönüştürmüştür. Bu dönüşüm, örgütlerin yönetilmesi için yeni bir yaklaşımın şekillenmesine neden olmuştur. Bu ihtiyaca cevaben, Genel Sistem Teorisi ortaya atılmıştır. Açık sistem anlayışı ile Modern Yönetim Düşüncesinin temellerini atan Teori, kamu yönetimi alanındaki reformların da ilham kaynağı olmuştur. Bu reformlar arasındaki en güncel örnek, 2018 yılında, yeni hükümet sistemiyle birlikte hayata geçirilen Politika Kurullarıdır. Kamu politikalarının belirlenmesi, izlenmesi ve değerlendirilmesi sürecinde hızlı ve istikrarlı karar alımına yardımcı olabilecek yeni bir kamu aktörü olarak oluşturulan Politika Kurulları, rolleri yasalarla tanımlı kurul üyeleri vasıtasıyla kamu politika paydaşları arasında çok aktörlü ve etkileşim merkezli bir yönetim anlayışı ile örgütlenmiştir. Çalışmanın amacı, Politika Kurulları ile Sistem Teorisinin fikri bağlarını ortaya koymaktır.

COVID-19 is the most common infectious disease of the last few years and has caused an outbreak all around the world. The mortality rate, which was earlier in the hundreds, increased to thousands and then to millions. Since January 2020, several scientists attempted to understand and predict the spread of COVID-19 so that governments may make sufficient arrangements in hospitals and reduce the mortality rate. This research article presents a comparative performance analysis of ARIMA, Prophet and Holt-Winters Exponential Smoothing forecasting methods to make predictions for the COVID-19 disease epidemiology in Europe. The dataset has been collected from the World Health Organization (WHO) and includes the COVID-19 case data of European countries, which is categorized by WHO between the years of 2020 and 2022. The results indicate that Holt-Winters Exponential Smoothing method (RMSE: 0.2080, MAE: 0.1747) outperforms ARIMA and Prophet forecasting methods.
Development of a New Ground Motion Model for a Peninsular Indian Rock Site

Published: December 2022

The ground motion model (GMM) plays a vital role in the generation of seismic design basis ground motion parameters. Even though many intra-plate GMMs are available, very few of them are based on Peninsular India (PI) region-specific seismological parameters. Hence, it is imperative to develop a GMM using seismological parameters derived from earthquakes in the Peninsular Indian region. In this study, a new GMM is developed for a PI rock site. Due to the scarcity of real earthquakes, artificial earthquake records are simulated to generate a new GMM for PI. The accelerograms of these artificial earthquakes are obtained from the stochastic finite fault simulation technique. Region-specific seismological parameters are obtained from the available PI earthquakes. The generated GMM is compared with other intra-plate GMMs for different earthquake magnitudes. Also, the generated GMM is validated with the Koyna earthquake record and it is observed that the GMM’s predictions are closer to the record.

MALİ DEMOKRASİ VE COVID-19 HARCAMALARI AÇISINDAN KARŞILAŞTIRMALI BİR ANALİZ
Authors: DOGAN Metin
Published: December 2022

Mali demokrasi, bireylerin aktif olarak bütçe süreçlerine katılabildiği, toplumun kamu bütçesine ait gelir ve harcamalar konusunda yeterli bilgiye ulaşabildiği ve sosyal anlamda kapsayıcılığın sağlandığı bir olguyu ifade etmektedir. Mali demokrasinin bir ülkede güçlü bir şekilde uygulanıp uygulanmadığının görülmesi açısından 2019’un son aylarında başlayan COVID-19 salgını önemli bir gösterge olmuştur. COVID-19 salgını milyonlarca insanın hayatını kaybetmesine neden olurken ekonomik ve sosyal sorunların küresel çapta büyümesine neden olmuştur. COVID-19’a bağlı bireylerin yaşadığı ekonomik ve sosyal sorunların çözümü ve salgının sonlandırılması için çalışmaların desteklenmesi gibi konularda hükümetlere büyük iş düşmektedir. Bu çalışma kapsamında yapılan analizde demokratik olarak olgunlaşmış, bütçe süreçlerinin şeffaf olduğu, refahın yüksek ve adil dağıtıldığı ülkelerde genel olarak COVID-19 kapsamında yapılan kamu harcamalarının Gayri Safi Milli Hasıla (GSYH)’dan daha fazla pay aldığı görülmektedir. Düşük demokratik standartlara sahip olup gelir adaletinin ve mali demokrasinin olmadığı ülkelerde ise COVID-19 harcamalarında bir azalma olduğu gözlemlenmiştir. İlerleyen yıllarda COVID-19’a benzer salgınların tekrar ortaya çıkacağı ve iklim değişikliğine bağlı aşırı doğa olaylarında sayısal bir artış olacağı beklenmektedir. Bu krizlere bağlı olarak da ekonomik ve sosyal riskler büyüyerek artacaktır. Bu yüzden özellikle otoriter ülkelerde kamu kaynaklarının daha etkin ve toplum lehine kullanabilmesi için mali demokrasi ilkelerinin doğru bir biçimde uygulanmasına ihtiyaç vardır.
