On the Topological Nature of the Stable Sets Associated to the Second Invariant of the Order $q$ Standard Lyness’ Equation
Authors: Bastien G. , Rogalski M.
Published: August 2024

We prove a conjecture asserted in a previous paper (see [2]) about order $q$ Lyness difference equation in ${\mathbb R}_*^+$:$u_{n+q}\,u_n=a+u_{n+q-1}+{\dots}+u_{n+1}$, with $a>0$. It is known that the function on ${{\mathbb R}_*^+}^q$ defined by\begin{multline*}H(x)=\frac{(1+x_1+x_2)(1+x_2+x_3)\dots}{x_1\dots x_q}\\\frac{(1+x_{q-1}+x_q)(a+x_1x_q+x_1+x_2+{\dots}+x_q)}{ x_1\dotsx_q}\end{multline*}is an {\sl invariant} for this equation. It is conjectured in [2] (and proved for $q=3$ only) that if $M>M_a:=\min H$ is {\sl sufficiently near} to $M_a$, then the set $S(M):=\{x\,|\,H(x)=M\}$ is homeomorphic to the sphere $\mathbbS$$^{^{q-1}}$. Here we prove this conjecture for every $q\geq 3$, and deduce from it that if the equilibrium $L$ of the map $T$ associated to the Lyness' equation, where $H$ attains its minimum, is for some $q$ {\sl the only critical point} of $H$, then the sets $S(M)$ are, for this $q$, homeomorphic to $\mathbbS$$^{^{q-1}}$ for every $M>M_a$, and that this is the case for $q$=3, 4 or 5.

Hereditarily Irreducible Mappings of Cartesian Product of Continua
Authors: Lončar Ivan
Published: August 2024

In Section 2 we shall prove that if Cartesian product $X\times Y$ of nondegenerate continua admits a hereditarily irreducible mapping $f:X\times Y\rightarrow Z,$ then w$(X\times Y)$=w$(Z)$.
The main section of the paper, Section 3, contains theorems concerning the Whitney maps on continua. In particular, it is proved that the product $\Pi \{X_{s}:s\in S\}$ of nondegenerate continua admits a Whitney map for $C(\Pi \{X_{s}:s\in S\})$ if and only if it is metrizable.

We discuss the general theory of radicals of paragraded rings, establish that the ADS-Theorem holds, and characterize paragraded normal radicals. It is known that any special radical of a ring can be described by the appropriate class of modules over that ring. In this note we show that all special paragraded radicals of paragraded rings can be described by the appropriate class of their paragraded modules.

Definable Groups for Dependent and 2-Dependent Theories
Authors: Shelah Saharon
Published: August 2024

Let $T$ be a (first order complete) dependent theory, ${\gC}$ a $\bar\kappa$-saturated model of $T$ and $G$ a definable subgroup which is abelian. Among subgroups of bounded index which are the union of $< \bar\kappa$ type-definable subsets there is a minimal one, i.e. their intersection has bounded index. See history in \cite{Sh:876}. We then deal with definable groups for 2-dependent theories, a wider class of first order theories proving that for many pairs $(M,N)$ of models, the minimal bounded subgroup definable over $M \cup N$ is the intersection of the minimal ones for $M$ and for $N$.

Tall, Strong, and Strongly Compact Cardinals
Authors: Apter Arthur
Published: August 2024

We construct three models in which there are different relationships among the classes of strongly compact, strong, and non-strong tall cardinals. In the first two of these models, the strongly compact and strong cardinals coincide precisely, and every strongly compact/strong cardinal is a limit of non-strong tall cardinals. In the remaining model, the strongly compact cardinals are precisely characterized as the measurable limits of strong cardinals, and every strongly compact cardinal is a limit of non-strong tall cardinals. These results extend and generalize those of of [3] and [1].
Multivariate Approximation With Rates by Perturbed Kantorovich-Shilkret Neural Network Operators
Authors: Anastassiou George A.
Published: August 2024

This paper deals with the determination of the rate of convergence to the unit of Perturbed Kantorovich-Shilkret multivariate normalized neural network operators of one hidden layer. These are given through the multivariate modulus of continuity of the engaged multivariate function or its high order partial derivatives and that appears in the associated multivariate Jackson type inequalities. The activation function is very general and it can derive from any multivariate sigmoid or bell-shaped functions. The right hand sides of our Jackson type inequalities do not depend on the activation function. The sample functionals are Kantorovich-Shilkret type. We provide an application for the first partial derivatives of the involved function.

In this paper we give an additional characterizations of the first order complete superstable theories, in terms of an external property called representation. In the sense of the representation property, the mentioned class of first-order theories can be regarded as "not very complicated". This was done for "stable" and for "$ {\aleph_0}$-stable." Here we give a complete answer for "superstable".

Waiving the positive definiteness of the leading matrix $\mathbf{A}$ in a hyperbolic quadratic eigenvalue problem $\mathbf{Q}(\lambda)\mathbf{x}=(\lambda^2\mathbf{A}+\lambda \mathbf{B}+\mathbf{C})\mathbf{x}=\mathbf{0}$, $\mathbf{x}\neq \mathbf{0}$ one obtains a definite eigenvalue problem, which is known to have $2n$ eigenvalues in $\mathbb R\cup\{\infty\}$.One of the characterizations of the definite quadratic eigenvalue problem is the existence of parameters $\xi$ and $\mu$ so that $\mathbf{Q}(\mu)$ is positive definite and $\mathbf{Q}(\xi)$ is negative definite, where $\xi$ and $\mu$ are not known in advance. In this paper we consider theimpact of the properties of the stiffness matrix $\mathbf{C}$ of the quadratic pencil $\mathbf{Q}(\lambda)$ on the corresponding definite quadratic eigenvalue problem and on the localization of the parameters $\xi$ and $\mu$.

Published: August 2024

The notion of compactness in the L-slice $(\sigma,J)$ of a locale $ L $ is introduced and we show that L-slice compactness is stronger than topological compactness and localic compactness. A subspace $ Y $, of the spectrum $Sp(L)$ of the locale $ L $, is constructed using filters $F_{x}=\{a \in L: \sigma(a,x)=x\}$ for compact elements $ x \in(\sigma,J)$ and the compactness of the subspace $ Y $ is characterised using the existence of a maximal compact element in the L-slice $ (\sigma,J) $.

A Literature Review to Investigate Data Analytics Tools for The Allocation of Resources in Cloud Computing
Authors: Sekwatlakwatla Sello Prince , Malele Vusumuzi
Published: August 2024

To ensure efficient operations and cost-effectiveness, resource management in cloud computing entails managing cloud resources to satisfy application needs, financial restrictions, and security. In this regard, utilizing data analytics tools for the allocation of resources in cloud computing to efficiently predict, track, allocate, and monitor resources enables businesses to make informed decisions based on real-time data, which plays a crucial role in resource allocation. Organizations adopting cloud computing services face increased network traffic, limiting traffic routing flexibility and causing excess traffic to reach unprepared physical nodes due to an inability to adjust to real-time traffic changes. This paper uses a systematic literature review to investigate the data analytics techniques used for resource allocation in cloud computing. It uses data from 2019 to 2024, sourced from different research databases. The results show that the majority of data analytics tools, including ARIMA and SVM, are employed for resource allocation in cloud computing. This study offers guidance to organizations regarding data analytics tools for the allocation of resources in cloud computing, and the recommendations can be utilized for the enhancement of the results in cloud computing, as well as to scholars by suggesting techniques to further investigate resource allocation to address the current gaps in cloud computing

SEXUAL CHARACTERISTICS OF INTERCORTICAL RELATIONSHIPS IN THE DELTA RANGE OF THE POWER SPECTRUM WHEN PERFORMING ARBITRARY BIMANUAL PURPOSEFUL MOVEMENTS
Authors: Кононенко Николай Сергеевич , Ткаченко Павел Владимирович
Published: August 2024

Уровень бимануальной координации у лиц мужского и женского полов представлен разной результативностью, что объясняется особенностями организации сенсомоторной сферы у женщин и мужчин. Процессы возбуждения и торможения являются взаимодополняющими и способствуют эффективному построению двигательной системы. Целью исследования является изучение половых особенностей активации коры в дельта-диапазоне и выявление внутрисистемных корковых взаимосвязей при реализации сложноскоординированных бимануальных движений. Уровень активности мозга оценивался регистрацией дельта-ритма при проведении электроэнцефалографии, а результаты показателя координации — с помощью метода суппортметрии. Выявлены достоверные различия в тормозной активности коры больших полушарий и функциональных взаимосвязях ее центров, что обусловливает различия результирующей эффективности выполнения моторных программ. В женской группе ведущее значение в формировании моторной программы имеет высокая активность в дельта-диапазоне левой фронтальной ассоциативной коры и выраженная связь затылочной и премоторной области справа. У мужчин межполушарная асимметрия с торможением правого полушария способствует более совершенному результату.

The level of bimanual coordination in men and women is represented by different effectiveness, which is explained by the peculiarities of the organization of the sensorimotor sphere in women and men. The processes of excitation and inhibition are complementary and contribute to the effective construction of the motor system. The aim of the study is to study the sexual characteristics of cortical activation in the delta range and to identify intersystem cortical relationships in the implementation of complexly coordinated bimanual movements. The level of brain activity was assessed by recording the delta rhythm during electroencephalography, and the results of the coordination index using the method of supportmetry. Significant differences in the inhibitory activity of the cerebral cortex and the functional relationships of its centers have been revealed, which causes differences in the resulting effectiveness of motor programs. In the female group, high activity in the delta range of the left frontal associative cortex and a pronounced connection between the occipital and premotor regions on the right are of leading importance in the formation of the motor program. In men, hemispheric asymmetry with inhibition of the right hemisphere contributes to a more perfect result.

SARS COV-2 DELTA VARIANT STRUCTURAL PROTEINS: HOMOLOGY WITH OPPORTUNISTIC BACTERIA
Authors: Марьянович Александр Тимурович , Кормилец Дмитрий Юрьевич
Published: August 2024

Способность SARS CoV-2 уклоняться от иммунного ответа можно считать общепризнанной. Гомология белков коронавируса и человека может быть одним из механизмов иммунного уклонения. Дельта-вариант обязательно имеет структурные особенности, которые объясняют его специфические свойства. Целью нашего исследования было выяснить, изменяют ли мутации, произошедшие в структурных белках дельта-варианта, его гомологию с белками, присутствующими в организме человека, то есть собственно человеческими,  бактериальными и пищевыми. Используя инструменты биоинформатики, мы обнаружили гомологию на уровне гептамеров между структурными белками дельта-варианта и белками человека, а также белками некоторых условно-патогенных бактерий верхних дыхательных путей, легких и кишечника. Белки шиповый (S) и мембранный (M) дельта-варианта имеют большое количество сходств (гомологичных соответствий) с перечисленными белками, причем наибольшее количество — в случае мутации S:Δ156,157;R158G. Причина, по которой дельтавариант SARS CoV-2 обладает специфическими характеристиками, и прежде всего повышенной летальностью, скорее всего, кроется в мутации в положениях 156–158 шипового белка.

The capacity of SARS CoV-2 for immune evasion can be considered universally recognized. Coronavirus and human protein homology may be one of the mechanisms of immune evasion. Delta variant necessarily has structural features that explain its specific qualities. The aim of our study is to find out whether mutations in the structural proteins of Delta variant change its homology with proteins present in the human body, i.e. human, bacterial and dietary. Using bioinformatics tools we detected homology on the heptamer level between Delta variant structural proteins and human proteins as well as some opportunistic bacteria proteins of the upper respiratory tract, lung and gut. Delta variant spike (S) and membrane (M) proteins have a large number of similarities (homologous correspondences) with the listed proteins, with the S:Δ156,157;R158G mutation having the greatest amount. The reason why SARS CoV-2 Delta variant has specific characteristics, most importantly increased lethality, is most likely to be found in a mutation at positions 156–158 of spike protein.
Evidence Check: Suicide Aftercare Services

Published: August 2024

Discharge from hospital following a suicidal crisis is a crucial time for the provision of high-quality aftercare. Providing aftercare services has been demonstrated to reduce the risk of further suicide attempts, deaths, and to increase the likelihood that people will seek professional support when experiencing suicidal thoughts. this Evidence Check aims to provide a review of the evidence for suicide aftercare services and effective characteristics of these services, focusing on comprehensive aftercare services being provided in Australia. This review identified 53 relevant studies in the peer reviewed literature. As a search of the grey literature did not uncover a comprehensive overview of available services, an online survey of PHNs was undertaken to address this gap. Most studies found that comprehensive aftercare programs and brief intervention programs are effective (63% and 70% of studies respectively). There have been no comprehensive dismantling studies published which evaluate the effectiveness of individual components or characteristics of suicide aftercare programs. However, this review identified components and characteristics that were common to programs that effectively reduced suicide-related outcomes such as reattempts.

Freeing Aristotle’s Epagoge from Induction
Authors: Hobza Pavel ,   Philosophy Documentation Center
Published: August 2024

Although our notion of induction stems from the Aristotelian epagoge, it was probably Cicero who first translated it into Latin as inductio. I argue that, despite occasional similarities, Aristotle’s epagoge is different from induction. In the first part, I point out the differences in epagoge’s function and nature. (1) Unlike induction, epagoge can proceed both from particulars to universals and the other way round, being an application of universals to particulars. (2) While induction is taken to be a means for how to obtain universals, epagoge finds universals already at its disposal before starting to work. (3) Although, like induction, epagoge may in some contexts be considered a kind of logical inference, it is rather an intuitive or perception-like ability or capacity providing the connection between particulars and universals. In the second part, I deal with what Aristotle calls καθόλου and καθ’ ἕκαστον. Although they are usually rendered as ‘universal’ and ‘particular’, on closer inspection, they turn out to be different from these modern terms. Their relationship is to be understood as that between a whole and parts.

Does Aristotle offer a definition of the soul? In fact, he rejects the possibility of defining the soul univocally. Because “life” is a homonymous concept, so too is “soul”. Given the specific causal role that Aristotle envisages for form and essence, the soul requires multiple different definitions to capture how it functions as a cause in each form of life. Aristotle suggests demonstrations can be given which express these causal definitions; I reconstruct these demonstrations.
Aristotle on What Is ‘Beyond Us’ (ὑπὲρ ἡμᾶς)
Authors: Kranzelbinder Daniel ,   Philosophy Documentation Center
Published: August 2024

On three occasions Aristotle judges explanations by earlier thinkers to be simply ‘beyond us’ (ὑðὲñ ἡìᾶò), namely, at Meta. iii 4, GA i 18, and GA ii 8. What failure is Aristotle charging earlier scientists with when he says this? I argue that the phrase ‘beyond us’ introduces a carefully considered charge (as opposed to an empty dismissal): an explanation of fact p is ‘beyond us’ when and only when it posits an explainer q that is (i) empirically unverifiable and (ii) will explain only this one fact p and no other facts.
Justice and the Democratization of Finance
Authors: Nici Lenart ,   Philosophy Documentation Center
Published: August 2024

What would it mean for the institutions of finance to be democratized? I explore this question from a broadly Rawlsian conception of justice. In the first part of the paper I outline Rawls’s theory of justice. In the second part I briefly review what Rawls had to say about justice in the economic sphere. Notably, he thought that his conception of justice can only be realized in either “Property-Owning Democracy” or “Liberal Socialism.” I briefly explore the nature of these two “regimes,” before turning my attention to the institutions of finance, and in particular banking. In the third part I discuss the role of finance in contemporary liberal democracies, the social and political power that private banks are endowed with in such societies, and what problems this engenders from the perspective of justice. In the fourth part I argue that, among other things, the democratization of finance would entail wide dispersal of power and control over decisions about finance and investment. In the fifth and final part of the paper, I argue that there are reasons to believe that both of Rawls’s just economic regimes would fail with respect to the distribution of power and control in the economy.

Published: August 2024

Context.—

The Japanese Society of Hepato-Biliary-Pancreatic Surgery guidelines propose a classification scheme that differs from the Union for International Cancer Control (UICC) system, in which the anatomic U-P point is the boundary between intrahepatic cholangiocarcinoma and perihilar cholangiocarcinoma (PCC).

Objective.—

To investigate whether this classification system improves clinicopathologic and genomic differentiation.

Design.—

Fifty-eight PCC cases defined by the UICC system were collected and classified into intrahepatic PCC (IPCC) and extrahepatic PCC (EPCC) categories using U-P point division. They were analyzed by next-generation sequencing using a panel that targeted 425 cancer-related genes.

Results.—

The IPCC group exhibited a significant larger tumor size compared with the EPCC group (4.67 ± 2.44 cm versus 2.50 ± 0.91 cm, P = .002). The mutation frequency of KRAS proto-oncogene, GTPase (KRAS) Q61 was also significantly higher in the IPCC group than in the EPCC group (16.7% versus 0.0%, P = .03). There were no statistically significant differences in other pathologic features or genomic characteristics, including tumor mutation burden and microsatellite instability. Significant differences in gene mutation rates, such as phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA; 0.0% versus 15.8%, P = .01) and tumor protein p53 (TP53; 34.5% versus 63.2%, P = .04), were observed between PCC and adjacent biliary tract cancers.

Conclusions.—

This study offers valuable insight into the clinicopathologic and genomic features of PCC. It is proposed that the U-P point division may have limited potential to refine the characterization of PCC regarding these features, and that the UICC classification system can readily demonstrate the molecular specificity of PCC.
Disseminated sandflies Sergentomyia and Phlebotomus in Al Muthanna province, Comparative and Taxonomic Study
Authors: Alyasiri Ali Jawad
Published: August 2024

The taxonomy of the subfamily Phlebotominae has undergone several changes since the early twentieth century, and even with several studies using both old and new tools, including molecular markers, doubts remain about the relationship and differences between them. These differences reflect a lack of knowledge of the true evolutionary history of flies. In parallel, the old and current classifications consider only adult morphological data. However, there is consensus among the authors on the importance of morphological data from all life stages. These discrepancies illustrate the need for new studies to provide hypotheses that could contribute to the classification of this subfamily. Phlebotomies (Diptera, Psychodidae, and Phlebotominae) have been extensively studied, mainly due to the role of these flies as primary vectors of various parasites, including various Leishmania species, Bartonella and viruses that cause many diseases to humans and other vertebrates. The studies started to collect and identify the Phlebotominae sand fly present in different areas of Al-Muthanna province. The studies also aimed to determine their numbers and classify them based on the approved scientific classifications, as well as the difference between the most important species in the province. Light traps and sticky traps were used, and using the insect classification by (J. Abul-Hab and S. A. Ahmed, 1984) and (Al-Mayali & Al-Hassani,2016), and 4 species were recorded during a ten-month period. Within the identified four species, a total of 1486 specimens comprising four species of two genera were collected: Phlebotomus (two species) and Sergentomyia (two species). Phlebotomus papatasi 683 (45.967%) was the dominant species followed by Sergentomyia sentoni 380 (25.57%), Phlebotomus sergenti 290 (19.51%). Sergentomyia squamipluris 133 (8.95%) distributed among 822 females and 664 males.

This study explores the impacts and challenges of cyber harassment on Pakistani female journalists. Although female journalists persistently experience misogynist online harassment in their jobs, this topic has yet to receive due attention in the journalism landscape. This study is closely aligned with the social feminism theory, which supports equal rights for working female journalists. The study sample comprised seven Pakistani female journalists, selected using purposive and snowball sampling. Adopting a qualitative research methodology, in-depth interviews were utilised for data collection to gain a comprehensive understanding of their experiences and perspectives. As revealed by the analysis, criticism of their work often takes the form of misogynistic attacks. These attacks include accusations of attention-seeking, discreditation of their skills, infantilisation, unsolicited images, misogynist slurs and even coercive fantasies of sexual violence and rape. As verified by the participants, the effects of this form of harassment are profoundly felt in their personal lives. It leads to mental exhaustion, self-doubt, coerced coping as well as the adoption of additional safety precautions in one’s personal life. The harassment also impacts the professional lives of female journalists as it forces them to withdraw from social media and coverage of specific topics, endure interruptions at work, take additional safety precautions at work and some, to the extent of considering to quit their jobs. As a result, all participants were unanimous in their demands for fundamental changes within the newsroom and society. The study demonstrates how Pakistani media organisations fall short of achieving UN’s SDG 5, which is gender equality, which this research closely aligns with.
