Katholische Theologie in den USA
Authors: Dahlke Benjamin
Published: September 2024

Seit dem Zweiten Weltkrieg hat die katholische Theologie in den USA Zug um Zug ein ganz eigenes, unverwechselbares Profil gewonnen: Indem sie die Glaubenslehre unter Einbeziehung der gesellschaftlichen und kirchlichen Wirklichkeit in den Vereinigten Staaten reflektiert, ist sie zugleich amerikanisch und katholisch. Im deutschsprachigen Raum sind bislang lediglich einzelne theologische Entwürfe bekannt. Eine umfassende Darstellung, die auch kulturelle, geschichtliche und politische Faktoren einbezieht, fehlt dagegen. Das Buch von Benjamin Dahlke schließt diese Lücke. Auf kundige Weise zeichnet der Autor die großen Entwicklungslinien der katholischen Theologie in den USA seit 1945 nach und bietet einen kompakten Überblick über eine bedeutende, eigenständige theologische Landschaft mit weltweiter Ausstrahlungskraft.
Tod – Ende und Anfang

Allen Säkularisierungstendenzen

zum Trotz bleibt christliches Gedankengut ein

Kulturfaktor und es zeigt sich, dass nicht nur Religion(en) über einen

Wissensschatz verfügen, der zuweilen in unerwarteten Momenten verstehen

hilft, sondern auch wissenschaftliche Theologie eine Hermeneutik

des Verstehens leisten kann: Zutiefst Menschliches – und damit echt

Göttliches – findet sich dort, wo der Mensch nach sich selber, ihrem/

seinem Sein und Sinn fragt – oder die Banalität menschlicher Existenz

durch eine Nähe unterbrochen wird, die nur durch Zuneigung, Hinwendung,

Einlassen und Sich-Öffnen zu erklären ist. Vor diesem Hintergrund

gliedert sich der Hauptteil des vorliegenden Werkes in eine

Erschließung des kulturellen Diskurshorizontes.
Perspective Chapter: Visualizing the Unseen – Multilayered Narrative of Violence in Graphic Novels by Francophone Middle Eastern Women
Authors: Pasandi Haniyeh
Published: September 2024

This chapter focuses on the post-9/11 testimonies of women from the Middle East whose work has gained international recognition. It explores four graphic novels written by female authors with a Middle Eastern background: Persepolis (Marjane Satrapi), A Game for Swallows (Zaina Abirached), Bye Bye Babylon (Lamia Ziadé), and Poppies of Iraq (Brigitte Findakly). Within this examination, the chapter delves into the various visual techniques used by these authors to unfold/re-view the layers of violence that these women experienced. Through their works, they experiment with diverse representational possibilities, aiming to capture the psychic impact of distressing experiences on both individuals and the collective.

Acute myeloid leukemia (AML) represents a significant therapeutic challenge despite progress; also, the management of patients aged below 60 remains challenging. This demographic typically exhibits a heterogeneous response to treatment, influenced by genetic, molecular, and clinical factors. The cornerstone of AML treatment encompasses induction chemotherapy aimed at achieving complete remission, followed by consolidation therapy to eliminate residual disease. Recent advances have introduced targeted therapies, such as FLT3 inhibitors and IDH1/2 inhibitors, which have shown promise in improving outcomes in specific patient subsets with relevant genetic mutations. Allogeneic hematopoietic stem cell transplantation (HSCT) remains a critical component for those at high risk of relapse, offering a potential cure in the post-remission phase. The decision-making process for treatment is complex, necessitating a personalized approach based on cytogenetic and molecular aberrations.
Analysis of domestic and foreign experience of research on online dating as a method of searching for a potential partner
Authors: Белова О.Ю. , Серякова С.Б.
Published: September 2024

в настоящее время виртуальные социальные сети постепенно становятся привычными спутниками жизни практически каждого человека в любом возрасте. В данной статье представлен теоретический анализ отечественных и зарубежных исследований возможностей и особенностей социальных сетей с целью поиска потенциального партнёра. Современные психологические исследования, ориентированные на онлайн-пространства, в первую очередь обращают внимание на изучение феноменов аддикции, влияния интернета на восприятие и психику, а изучение темы особенностей поиска потенциального партнера по средствам интернет-платформ представляется мало разработанной. Такой анализ является актуальным для определения возможных новых форм осуществления выбора спутника жизни, а также для формирования представлений о том, как развитие технологий и активное включение социальных сетей в современную жизнь, отражаются на отношениях и способах знакомства. Методом исследования выступает теоретический анализ отечественной и зарубежной научной литературы. Результаты анализа раскрывают такие различные аспекты данной темы, как предпочтения в выборе партнёра посредством онлайн-знакомств, степень успешности такого метода по сравнению с традиционными способами знакомства. Сформулированные выводы могут быть полезны для построения психологических и социологических исследований влияния онлайн-знакомств на личную жизнь, а также для формирования представлений об оптимальных способах поиска партнера для успешных взаимоотношений.

nowadays virtual social networks are gradually becoming habitual companions of almost every person's life at any age. This article presents a theoretical analysis of domestic and foreign studies of the possibilities and peculiarities of social networks in order to find a potential partner. Modern psychological researches, oriented on online spaces, first of all pay attention to the study of addiction phenomena, the influence of the Internet on perception and psyche, and the study of the topic of peculiarities of searching for a potential partner by means of Internet platforms seems to be little developed. Such analysis is relevant for determining possible new forms of choosing a life partner, as well as for forming ideas about how the development of technology and the active inclusion of social networks in modern life affect relationships and ways of dating. The research method is theoretical analysis of domestic and foreign scientific literature.The results of the analysis reveal such different aspects of this topic as preferences in choosing a partner through online dating, the degree of success of this method compared to traditional ways of dating.The formulated conclusions can be useful for the construction of psychological and sociological studies of the influence of online dating on personal life, as well as for the formation of ideas about the optimal ways of finding a partner for successful relationships.

Features of the relationship of need and readiness in human activity
Authors: Тарасова Н.Ю. , Губарев Ю.А.
Published: September 2024

данная статья посвящена рассмотрению особенностей взаимосвязи потребности и готовности в деятельности человека и отражению их компонентной структуры. Любая потребность является выразителем человека, его активности. Потребность формируется не сама по себе, а под воздействием извне. Позыв к чему-то или кому-то есть явная необходимость для человека, осознанная и принятая им. Мыслительный акт человека о разрешении потребности в направлении совершения определенных действий прежде должен получить отклик о готовности. Выводы: потребности и готовность являются взаимозависимыми феноменами и выражают стремление человека к выполнению определенных действий. Связь потребности и готовности проявляется за счет внешних и внутренних мотивирующих факторов, которые обусловливают осознание человеком настоящих и будущих явлений и процессов и побуждают к деятельности.

this article is devoted to considering the features of the relationship between need and readiness in human activity and reflecting their component structure. Any need is an expression of a person and his activity. The need is not formed on its own, but under external influence. The urge to something or someone is a clear need for a person, recognized and accepted by him. A person’s mental act of resolving a need in the direction of performing certain actions must first receive a response of readiness. Conclusions: needs and readiness are interdependent phenomena and express a person’s desire to perform certain actions. The connection between need and readiness is manifested due to external and internal motivating factors that determine a person’s awareness of present and future phenomena and processes and encourage action.

Published: September 2024

цель: изучение особенностей клинического течения заболевания, качества жизни и цитокинового профиля у пациентов с истинной экземой в хронической стадии и депрессией. Материалы и методы. В исследовании приняли участие 157 пациентов с истинной экземой в хронической стадии: 66 пациентов с коморбидной депрессией и 91 – без коморбидной депрессии. Для определения симптомов депрессии использовали шкалу Монтгомери-Асберга. Результаты. Пациенты с истинной экземой в хронической стадии и депрессией характеризовались более молодым возрастом (р=0,021), более тяжелым течением заболевания по индексам ЕASI (р<0,001), Pruritus (р=0,014), более высокой частотой рецидивов (р=0,012) и более низким уровнем качества жизни по опроснику DLQI (р<0,001), а также более высокими значениями IL-6 и TNF-α (р=0,011 и р=0,001). Установлена обратная корреляция между средним значением по шкале Монтгомери-Асберга и возрастом пациентов (r=-0,62; р=0,002), прямая – средними значениями по индексам ЕASI (r=0,73; р=0,001), Pruritus (r=0,60; р<0,001), DLQI (r=0,69; р=0,001) и TNF-α (r=0,61; р=0,013). Заключение. У пациентов с депрессией истинная экзема в хронической стадии протекает тяжелее, сопровождается нарастанием системных провоспалительных сдвигов и более существенным снижением качества жизни.

aim: to study the features of the clinical course of the disease, quality of life and cytokine profile in patients with true eczema in the chronic stage and depression. Materials and methods. The study involved 157 patients with true eczema in the chronic stage: 66 patients with comorbid depression and 91 without comorbid depression. The Montgomery-Åsberg scale was used to determine symptoms of depression. Results. Patients with true eczema in the chronic stage and depression were characterized by a younger age (p=0.021), a more severe course of the disease according to the EASI indices (p<0.001), Pruritus (p=0.014), a higher frequency of relapses (p=0.012) and more low level of quality of life according to the DLQI questionnaire (p<0.001), as well as higher values of IL-6 and TNF-α (p=0.011 and p=0.001). An inverse correlation was established between the average value on the Montgomery-Åsberg scale and the age of the patients (r=-0.62; p=0.002), direct correlation – with the average values on the EASI (r=0.73; p=0.001), Pruritus (r= 0.60; p<0.001), DLQI (r=0.69; p=0.001) and TNF-α (r=0.61; p=0.013). Conclusion. In patients with depression, true eczema in the chronic stage is more severe, accompanied by an increase in systemic pro-inflammatory changes and a more significant decrease in quality of life.
PREVALENCE OF WHITE SPOTTING IN THE PLUMAGE OF THE FULVOUS WREN CINNYCERTHIA FULVA IN THE BOLIVIAN ANDES
Authors: Cortes-Romay Rhayza , Rechberger-Lopez Johan , Montano Centellas Flavia
Published: September 2024

We assessed the prevalence of white-spotting in the plumage of a Fulvous Wren Cinnycerthia fulva population and present evidence that this phenomenon occurs in other species populations. We captured and observed individuals with varying white facial patches in Cotapata National Park (La Paz, Bolivia). Fifty-two percent of the captured individuals (N=17) showed some degree of white feathering; in all cases, white patches occurred only on the head and fitted the description of ‘white-spotting’, a pattern likely associated with age, physical fitness and status. In avian community surveys, we often observed Fulvous Wrens attending mixed-species flocks, and 36% of all the flocks had at least one individual with facial white-spotting. An examination of photographic records of the species showed that spotting occurs in other populations, with most records from Bolivia showing some degree of facial white-spotting. Our study exemplifies the utility of citizen-science platforms for documenting atypical plumage in wild bird populations.

Normal science is characterized as the central concept of Kuhn’s theory, as the major novelty it introduces. What Kuhn expresses regarding themes such as research traditions, scientific revolution, incommensurability, and scientific progress can therefore be well understood only by reference to his concept of normal science. From this perspective, the article examines some critical observations frequently formulated by philosophers of science regarding the theory presented in The Structure....
Epistemologia evoluționistă, problema naturalizării și caracterul adaptativ al gândirii raționale
Authors:   Institutul de Filosofie si Psihologie al Academiei Romane, Balan Sergiu
Published: September 2024

I will try to explain why I think evolutionary epistemology (EE) is legitimately built on a functional analogy, explaining how I think this kind of analogical reasoning works. Based on an idea from a Charles Darwin notebook, I will argue that the interest in EE is at least as old as the theory of evolution by natural selection itself. I will then try to show how EE fits into Quine’s broader programme of naturalizing epistemology and what it brings in addition to his original project, which is threatened by the danger of circular reasoning. I will argue that an idea of David Hume about how one can justify the belief in the principle of uniformity of nature, reinterpreted in EE, can help us avoid this danger. Finally, I will try to show how certain ideas from EE can help us address some controversial aspects concerning the status of human cognitive faculties, such as the question regarding the adaptive or maladaptive character of rational thought.

Cultura si memorie (I) Elemente pentru o fenomenologie a canonului cultural
Authors:   Universitatea Nationala de Arte din Bucuresti, Bambulea Luigi
Published: September 2024

The author tries to find the necessary support for his approach, concerning the cultural memory, in bergsonian phenomenology, in which the elements of psychological observation are not yet sharpsly separated; so they can serve as a fruitful field of research, especially since the phenomenon of memory has an essential psychological dimension. Briefly, this reflection investigates the possible conditions of culture in a world of nature, and memory in a world of matter. Conclusions: First of all, the past (being patrimonialised and metabolised), reverberating in the present, represents the sub-ego of the communities – their veritable hypokeimenon. Furthermore, memory has an eminent sense of identity, as the past’s relevance for the present existence is decisive, to the extent that the heritage provides geometrising schemes of reality – hence the possibility of a crystalised vision of the world –, and to the extent that the immediate future can be considered a probability wave of the past; the decline of impersonal piety towards tradition is a symptom of identity destruction.
Hobbes and Locke on the state of nature and what threatens peace in society
Authors:   Institutul de Filosofie si Psihologie al Academiei Romane, Grigore Nora
Published: September 2024

In my paper, I will argue that, although it is common knowledge that Hobbes and Locke strongly and openly disagree about the desirable form of government, and equally have different description of the state of nature, the careful reader might notice that after all the needed qualifications are added and the colours of persuasion removed (i.e. the violence of homo homini lupus for Hobbes and the idyllic peace and abundance of resources for Locke), the state of nature à la Hobbes is not significantly different from the state of nature à la Locke. Which makes room for the subsequent question that I plan to address here: if the starting point is in both cases (almost) the same, how could the desired (and somehow resulting) forms of government be so different?
Organic Farming Techniques:Enhancing Sustainability and Resilience in East Africa
Authors:   Faculty of Engineering Kampala International University Uganda, Rita Lillian Nakiyingi
Published: September 2024

This review underscores the transformative potential of organic farming techniques in East Africa, highlighting their role in promoting sustainability, resilience, and economic viability in the face of environmental and socioeconomic challenges. Organic farming techniques, which use natural processes and biological diversity, are a sustainable alternative to conventional agricultural practices in East Africa. These techniques, such as composting, crop rotation, integrated pest management (IPM), mulching, and biofertilizers and biopesticides, improve soil structure, prevent pest buildup, reduce reliance on chemical pesticides, and enhance water efficiency and soil health. These practices enhance food security, environmental sustainability, and economic viability for smallholder farmers. Water management practices like drip irrigation and rainwater harvesting optimize water use, while agroforestry systems promote soil fertility, biodiversity, and climate resilience. Crop diversity and resilience strategies, like polyculture and heirloom cultivation, improve agricultural sustainability. Community-based farming initiatives empower local communities, enhancing food security and sustainable natural resource management. Climate-smart agriculture practices enhance productivity, resilience to climate change, and greenhouse gas mitigation. Technological innovations, particularly in ICTs, provide precision agriculture, market access, financial inclusion, and digital extension services. Despite challenges like the digital divide and infrastructure constraints, continued investment in technology, public-private partnerships, capacity building, and supportive policies is crucial.

Encoding Schemes in FHE
Authors: Kun Jeremy
Published: September 2024

In cryptography, we need a distinction between a cleartext and a plaintext. A cleartext is a message in its natural form. A plaintext is a cleartext that is represented in a specific way to prepare it for encryption in a specific scheme. The process of taking a cleartext and turning it into a plaintext is called encoding, and the reverse is called decoding. In homomorphic encryption, the distinction matters.

Modulus Switching in LWE
Authors: Kun Jeremy
Published: September 2024

The Learning With Errors problem is the basis of a few cryptosystems, and a foundation for many fully homomorphic encryption (FHE) schemes. In this article I’ll describe a technique used in some of these schemes called modulus switching. In brief, an LWE sample is a vector of values in $\mathbb{Z}/q\mathbb{Z}$ for some $q$, and in LWE cryptosystems an LWE sample can be modified so that it hides a secret message $m$.

Published: September 2024

In my book I discuss the importance of context in reading and writing mathematics. An early step in becoming comfortable with math is deciphering the syntax of mathematical expressions. Another is in connecting the symbols to their semantic meanings. Embedded in these is the subproblem of knowing what to call the commonly used symbols. The more abstract you go, the more exotic the symbols tend to get.

Published: September 2024

We’re glibly searching for counterexamples to the Riemann Hypothesis, to trick you into learning about software engineering principles. In the first two articles we configured a testing framework and showed how to hide implementation choices behind an interface. Next, we’ll improve the algorithm’s core routine. As before, I’ll link to specific git commits in the final code repository to show how the project evolves.

This essay is a slightly modified version of the closing chapter of A Programmer’s Introduction to Mathematics. We are no longer constrained by pencil and paper. The symbolic shuffle should no longer be taken for granted as the fundamental mechanism for understanding quantity and change. Math needs a new interface. –Bret Victor, “Kill Math” Math is a human activity.
Shift Networks
Authors: Kun Jeremy
Published: September 2024

In my recent overview of homomorphic encryption, I underemphasized the importance of data layout when working with arithmetic (SIMD-style) homomorphic encryption schemes. In the FHE world, the name given to data layout strategies is called “packing,” because it revolves around putting multiple plaintext data into RLWE ciphertexts in carefully-chosen ways that mesh well with the operations you’d like to perform.
Searching for RH Counterexamples — Adding a Database
Authors: Kun Jeremy
Published: September 2024

In the last article we set up pytest for a simple application that computes divisor sums $ \sigma(n)$ and tries to disprove the Riemann Hypothesis. In this post we’ll show how to extend the application as we add a database dependency. The database stores the computed sums so we can analyze them after our application finishes. As in the previous post, I’ll link to specific git commits in the final code repository to show how the project evolves.

Authors: Kun Jeremy
Published: September 2024

In this article I’ll derive a trick used in FHE called sample extraction. In brief, it allows one to partially convert a ciphertext in the Ring Learning With Errors (RLWE) scheme to the Learning With Errors (LWE) scheme. Here are some other articles I’ve written about other FHE building blocks, though they are not prerequisites for this article.

Authors: SALHI Mohamed lamine , OUNIS Houdayfa , MELLAS Mekki
Published: September 2024

The present work is a contribution to the study of the effects of temperature on vibrations and stability of laminated composite plates using the finite element method. Thus, a DMQP/ml bending finite element with 4 nodes and 3 degrees of freedom based on the first order shear theory is extended to consider the effects of temperature on vibration and stability of laminated composite plates. The effect of the dependence of material properties on temperature as well as the effect of the of thermal stresses on the natural frequencies of laminated plates are studied simultaneously. A parametric study was carried out to highlight the effect of certain parameters on the vibration behavior of the laminated plates. The study showed that in most cases, the natural frequencies of vibration decrease with the increase in temperature. On the other hand, if the temperature inflicted on the plate coincides with the critical buckling temperature, the natural frequencies tend towards zero. Moreover, based on experimental data, this paper presents a study of the effect of temperature on the vibration behavior of a laminated T300/5208 Graphite/Epoxy plate. The study showed that temperature significantly changes the properties of the materials as well as the vibration behavior of the plate.

Authors: Phukan Parismita , Deka Hiren , Haloi Puja , Hazarika Gopal Chandra
Published: September 2024

The purpose of this study is to examine the entropy generation for a Magnetohydrodynamic flow of a Casson fluid subject to a vertical cone. Here the impact of reaction by chemical and diffusion-thermo is scrutinized. Physical aspects of radiative flux transverse to the surface are deliberated. The governing non-linear PDEs and the expression for entropy generation are non-dimensionalized with the help of dimensionless quantities. Finite difference technique is implemented to get numerical and graphical results for the non-linear system. Bejan number for the heat transfer is also examined. The results obtained shows that entropy generation and Bejan number are strongly influence by the embedded flow parameters.

Published: September 2024

The automotive, aerospace and marine industries make extensive use of aluminum and its alloys to produce a wide variety of components. This prompts research work related to improving manufacturing processes using these materials. One of the main problems in this area is the durability of cutting tools. This article describes the results of tests on the wear of coated and uncoated carbide cutting tools during turning of EN AW 2007 aluminum alloy. The tests were carried out under dry conditions and at higher cutting speeds. On the face rake the VBB indicator (average width of flank wear), and on the rake face the KB indicator (crater width on the rake face) were evaluated. Only for the uncoated insert the break-in period, steady-state wear region and intensive wear was observed, and the limiting value of the VBB indicator was obtained after 36 minutes of tool life. The TiAlN+TiN coated insert, as well as TiCN achieved very short tool life periods of 16 and 24 minutes, respectively. Compared to the uncoated and TiCN coated insert, a VBB increase of about 170% was obtained for the TiAlN+TiN coated insert after 16 minutes. In contrast, an increase in the VBB of almost 60% was obtained for the TiCN coated insert after 24 minutes, compared to the uncoated insert. Compared to the uncoated insert, an increase of 12.1% in the KB value was obtained for the TiCN coated insert, and 18.2% for the TiAlN+TiN coated insert.

Published: September 2024

The time dependent Couette flow of an electrically conducting fluid in a horizontal annulus in the presence of electric potential and accelerated motion of the outer cylinder is investigated. The governing electric field potential as well as the momentum equations are obtained from Poisson–Boltzmann and Navier-Stokes equations respectively. As a promising tool for solving time-dependent problems, the Laplace transform technique is used to obtain analytical solution for electric field and velocity profile in Laplace domain. Using the Riemann-sum approximation simulation, the results are obtained numerically in time-domain. In the course of numerical and graphical representations of results, it is found that the magnitude of electrokinetic effect as well as Debye-Hückel parameter play important role in flow formation and mass flow rate in the horizontal annulus. Further, velocity, skin-friction and mass flow-rate decrease with increase in Debye-Hückel parameter at all-time regardless of the mode of application of magnetic field. In addition, mass flow-rate can be enhanced with increasing Hartmann number when the magnetic field fixed relative to the moving cylinder.

Authors: Harrison Gregory Bruce , Cohen Adam Ryan
Published: September 2024

The United States Navy operates a variety of small submersibles for the deployment of Naval Special Warfare Group (NSWG) teams. However, current delivery vehicles either cannot operate off a submarine, or are flooded, exposing their occupants to the open ocean. The team aimed to bridge this gap by designing a small, dry, submersible that can be operated from the dry deck shelter of a US Navy submarine. To achieve this, the team developed a conceptual design, and performed a hydrodynamical analysis using computational fluid dynamics (CFD). This design greatly increases the capability of the Navy and NSWG teams, increasing the safety and effectiveness of both the user and launch platform.
