The advantages of neomoorean antiskeptical strategy
Authors: Mijic Jelena
Published: February 2021

This paper aims to argue in support of the neo-Moorean attempt(s) to solve a
skeptical paradox. It defends the thesis that neo-Mooreans retain advantages
and avoid disadvantages of rival anti-skeptical strategies - namely
epistemic contextualism. The puzzle that a radical skeptic poses is
exemplified by Nozick?s famous Brain in a Vat thought experiment, which
enables construing valid arguments consisting of jointly inconsistent but
independently plausible premises. The first and the second part of the paper
are devoted to Nozick?s conditional analysis of knowledge and De Rose?s
epistemic contextualism, both based on the sensitivity principle. Referring
to De Roses? contextualist theory, we demonstrate that the failure of
Nozick?s conditional analysis of knowledge to provide a satisfactory answer
to a skeptical paradox does not concern the sensitivity principle but rather
closure denial and embracing the so-called ?abominable conjunction?. In the
third part, we point out the weaknesses of the presumably most successful,
contextualist response to the paradox. We explain that even though DeRose?s
anti-skeptical strategy is built upon Nozick?s theory, he successfully
surmounts its difficulties. Yet it seems that as a contextualist, he
necessarily makes some concessions to a radical skeptic. Eventually, the
article introduces Black?s neo-Moorean anti-skeptical theory based on the
sensitivity principle as a strategy that makes neither concessions, nor
counterintuitive proposals.

The Sz?sz-Mirakjan-Kantorovich operators and the Baskakov-Kantorovich
operators are shown to be controlled by the Hardy-Littlewood maximal
operator. The Sz?sz-Mirakjan-Kantorovich operators and the
Baskakov-Kantorovich operators turn out to be uniformly bounded in Lebesgue
spaces and Morrey spaces with variable exponents when the integral exponent
is global log-H?lder continuous.
Computer tools for the construction and analysis of some efficient root-finding simultaneous methods
Authors: Petkovic Ivan , Herceg Djordje
Published: February 2021

Using the tools provided by computer algebra system Mathematica, we consider
two iterative methods of high efficiency for the simultaneous approximation of
simple or multiple (real or complex) zeros of algebraic polynomials. The
proposed methods are based on the fourth-order Schr?der-like methods of the
first and second kind. We prove that the order of convergence of both basic
total-step simultaneous methods is equal to five. Using corrective
approximations produced by methods of order two, three and four for finding
a single multiple zero, the convergence order is increased from five to six,
seven, and eight, respectively. The increased convergence speed is attained
with negligible number of additional arithmetic operations, which
significantly increases the computational efficiency of the accelerated
methods. Convergence properties of the proposed methods are demonstrated by
numerical examples and graphics visualization by plotting trajectories of
zero approximations. Flows of iterative processes, presented by these
trajectories, point to the stability and robustness of the proposed methods.
Some analytic approximations for backward stochastic differential equations
Authors: Ðordjevic Jasmina
Published: February 2021

We consider an analytic iterative method to approximate the solution of the
backward stochastic differential equation of general type. More precisely, we
define a sequence of approximate equations and give sufficient conditions
under which the approximate solutions converge with probability one and in
pth moment sense, p ? 2, to the solution of the initial equation under
Lipschitz condition. The Z-algorithm for this iterative method is introduced
and some examples are presented to illustrate the theory.

Published: February 2021

Recent studies have demonstrated that social isolation during the 2020 COVID?19 pandemic has significantly impacted the mental and physical health of people worldwide. However, it remains unknown whether physical activity can improve mental health in a state of emergency. The present study aimed to examine the importance of physical exercising and stress management mechanisms (problem-focused, emotion-focused, and avoidant) in the context of mental health indicators (depression, anxiety, and nonspecific stress) in conditions of social isolation during COVID?19-induced lockdown in Serbia. The sample consisted of 680 adults (66% female), mean aged 35.91 years (SD = 12.45). The results indicated a significant relation between physical exercising and a reduced stress response and confirmed the usefulness of the already well-known problem-focused strategies. Avoidant and emotionfocused coping were associated with poorer mental health outcomes. However, as a moderator, physical activity lowered anxiety levels in individuals prone to emotion-focused coping.

Two floating object interact each other in a certain time when the initial separation distance of them is not greather than the radius. This interaction is caused by asymmetric deformation in the liquid-air boundary plane due to contact with spherical particles. Asymmetric deformation plane of the liquid-air boundary between the two spheres and outside the sphere results an attractive force. This force is experienced by two balls that interact in a certain period of time until they come close to each other and after contact they will bond and difficult to escape. The position of each ball is observed using a video camera with 25 fps specifications and processed using Python and OpenCV and obtained data on the position of the center of mass of the system at any time until both are in contact. From the equation of position to time, the acceleration value of the ball is obtained, so that the magnitude of the attractive force can be known. The attractive force of the object is varied with the density of the object.

A Water Seal Drainage (WSD) design was made to remove air and fluid from the pleural cavity in the thorax (lung cavity) using a connecting tube or chest tube to maintain the negative pressure of the cavity. Under normal circumstances, the pleural cavity has negative pressure and only a little pleural fluid is filled. Suction pumps have a high pressure with a pressure range of -10 kPa to -80 kPa. The pressure is large enough so that it is not suitable for thorax because it can cause damage to internal organs due to high pressure. WSD specifically for thorax has a low pressure which is below -5 kPa / -40 mmHg. This WSD is equipped with a hand switch, water level and automatic Arduino Uno based exhaust system which has a pressure below -26.6 kPa / -20 cmHg to suction and pressure below -3.4 kPa / -2.6 cmHg to remove liquid from the bottle . The hand switch itself functions as a manual control to make it easier for the user, while the level sensor functions as a safety level for fluid levels in the tool and also an automatic fluid disposal system so that it is more efficient.

Many biological processes in the human body are based on the diffusion system. Diffusion is defined as a process of random movement of the particle whose the direction is from high concentrations to low concentrations. Many of various study of diffusion have been done both experimentally and computationally. Because the particle interaction is stochastic, the Monte Carlo (MC) method is used in performing particle simulations. The main of MC method is the use of random numbers. Many software have provided uniform random number generators. But based on the analytic results, the solution is normal distribution. Therefore, Box-Müller can be used as a transformation of particle distribution. The software used, MATLAB, has a normal random generator. Therefore, the aims of this study is comparing particle distribution of these two different random number generator with MATLAB and showing the impact of timestep parameter to these random number generator. This result can be used as based for the modelling of more complex biological systems.

Revealing the place of God in the naturalistic worldviews of Leibniz and Newton using content analysis
Authors: Otyutskiy Gennady P.
Published: February 2021

The aim is to use examples of Leibnizian and Newtonian works to demonstrate the notion that, under certain conditions, the concept of God can function as a methodological tool for constructing an integral worldview. A content analysis of the texts of Leibniz and Newton was conducted to identify the role of God. The comparative analysis allowed the author to reveal similar aspects in these visions. The differences between Leibniz and Newton are profound, but what unites them is the diversity of their interests and their outstanding roles in the discovery of the analysis of infinitesimals. Natural science problems that could not be solved in the 17th century by exclusively scientific methods led to gaps in the complete view of the world. The concept of God not only made it possible to fill in such gaps, but also served as an instrument of research itself.
Seasons of a river
Authors:   , Edzerza Felicity Louise
Published: February 2021

Seasons of a River is a fictional story about a woman looking back on her life. In her recollections she has to acknowledge and come to terms with the fact that her relationships with indigenous people in Canada have been inequitable and unbalanced. She realizes that she has been in the role of helper, of ally, and as such has perpetuated ideas of colonization and oppression, despite her good intentions. The protagonist, Annan, is in the process of trying to understand the complicated issues involved with the helping industry and her part within that industry. My introduction discusses the power differentials within allyship relations. I discuss how liberalism, at the root of the helping industry, although seen as a positive ideology, often perpetuates inequities and injustices when dealing with groups that are seen as “different.” I also discuss the importance of relationship building and listening and the need for quelling the tendency to assist others without consultation. This introduction and story also contain themes of ageism and how these attitudes are woven into the fabric of society in such a way as to internalize oppression and the idea of staying in one’s “place.” Ultimately, this story is about transformation.
