  1. Teste gravitaționale.Nicolae Sfetcu - 2022 - Cunoașterea Științifică, Issn 2971-9070, Vol. 1, Nr. 1, Sept. 2022.
    Cele mai multe experimente au confirmat relativitatea generală cu ajutorul tehnologiilor nou dezvoltate. S-a creat o bază tehnologică pentru astronomia undelor gravitaționale. S-au construit antene barogene criogenice și antene interferometrice laser performante, asociate cu analiza teoretică a experimentelor cu masele de testare, rezultând că sensibilitatea experimentelor depinde de izolarea termică, dacă dispozitivul înregistrează continuu coordonatele sensibilitatea antenei este limitată, și se poate crește sensibilitatea dacă se folosesc proceduri cuantice. Antenele pot ajuta în observarea radiației gravitaționale de fond și testarea relativității (...)

  2. Teste gravitaționale ale relativității generale.Nicolae Sfetcu - manuscript
    Perioada dintre 1960 și 1980 a fost perioada de maturitate a relativității generale: s-au dezvoltat noi metode de testare de mare precizie care au inclus teste noi, precum precesiunea giroscopică, întârzierea luminii și "efectul Nordtvedt" în mișcarea lunară, utilizând inclusiv observații astrofizice și sateliții artificiali. Există diferențe mari de predicții între relativitatea generală și fizica clasică, precum dilatarea timpului gravitațional, lentila gravitațională, deplasarea spre roșu gravitațională a luminii, etc. Și există multe teorii relativiste ale gravitației, bifurcate sau independente, dar (...)

  3. Teste gravitaționale cosmologice.Nicolae Sfetcu - manuscript
    Modelele cosmologice actuale sunt construite pe baza relativității generale. Soluțiile ecuațiilor specifice, Friedmann-Lemaître-Robertson-Walker permit modelarea evoluției universului pornind de la Big Bang. O parte din parametrii universului au fost stabiliți prin observații. Pe baza acestora, și altor date observaționale, se pot testa modelele. Predicțiile includ abundența inițială de elemente chimice formate într-o perioadă de nucleosinteză în perioada Big Bang, structura ulterioară a universului, radiația cosmică de fond, etc. DOI: 10.13140/RG.2.2.22204.59525.

  4. Teste gravitaționale în câmp puternic.Nicolae Sfetcu - manuscript
    Când densitatea corpului devine suficient de mare, relativitatea generală prezice formarea unei găuri negre. Stelele neutronice de circa 1,4 mase solare și găurile negre sunt starea finală pentru evoluția stelelor masive. De obicei o gaură neagră într-o galaxie a jucat un rol important în formarea acesteia și a structurilor cosmice aferente. Astfel de corpuri oferă un mecanism eficient pentru emisia de radiații electromagnetice și formarea de microquasari. Accreția poate duce la jeturi relativiste. Relativitatea generală permite modelarea acestor fenomene, confirmate prin (...)

  5. Gravitația cuantică – Euristica și teste gravitaționale.Nicolae Sfetcu - manuscript
    În încercarea de dezvoltare a unei teorii solide a gravitației cuantice, au existat mai multe programe de cercetare, dintre care unele au căzut în timp în desuetitudine datorită puterii euristice mai mari a altor programe. Testul primordial al oricărei teorii cuantice a gravitației este reproducerea succeselor relativității generale. Aceasta implică reconstrucția geometriei locale din observabilele nelocale. În plus, gravitația cuantică ar trebui să prezică probabilistic topologia la scară largă a Universului, care în curând poate fi măsurabilă, și fenomene la scala (...)

  6. Teste și anomalii ale teoriilor clasice ale gravitației non-relativiste.Nicolae Sfetcu - manuscript
    În mod obișnuit, "laboratorul" testelor gravitaționale a fost corpurile cerești, sistemele astrofizice. Dar astfel de teste sunt perturbate de efecte non-gravitaționale. Cel mai utilizat astfel de "laborator" a fost sistemul solar. De curând, oamenii de știință s-au concentrat pe observarea pulsarilor binari pentru verificarea teoriilor gravitaționale, prin observațiile privind variațiile perioadei orbitale, furnizând astfel dovezi indirecte pentru emisia de radiație gravitațională. Dar experimentatorul nu poate ”aranja laboratorul” după nevoile sale, și nici declanșa anumite evenimente atunci când are nevoie de (...)

    Întrebarea de bază este, ce este o pseudoştiinţă? Una din cele mai disputate delimitări ale ştiinţei. Mulţi savanţi de renume mondial, unanim recunoscuţi (ca de ex. Charles Darwin) au cochetat de-a lungul timpului cu diverse aspecte ale pseudoştiinţei considerându-le, cu bună credinţă, drept ştiinţă.

Chiar şi în prezent, practicanţii pseudoştiinţelor nu recunosc valabilitatea etichetei puse domeniului lor de activitate. Oamenii de ştiinţă au tendinţa (...)

  10. Teorii alternative la relativitatea generală – Formalismul PPN.Nicolae Sfetcu - manuscript
    Imediat după elaborarea și succesul relativității generale, au început să apară teorii alternative pentru gravitație. În dezvoltarea acestor teorii s-au încercat multe strategii (euristici pozitive) diferite, prin adăugarea de noi ipoteze la TGR, utilizarea unui spațiu-timp pentru care universul este static, ipoteze care elimină singularitățile gravitaționale, etc. Pentru evaluarea modelelor de gravitație, au fost propuse mai multe seturi de teste. Formalismul post-newtonian ia în considerare aproximări ale ecuațiilor de gravitație ale lui Einstein prin abaterile de ordinul cel mai scăzut (...)

  12. Gravitația.Nicolae Sfetcu - 1901 - Drobeta Turnu Severin: MultiMedia Publishing.
    Prezenta lucrare abordează gravitația din punctul de vedere al fizicii fenomenlogice cu accent pe testele gravitaționale, al epistemologiei și metodologiei utilizate de oamenii de știință, și al ontologiei gravitației, spațiului și timpului. Gravitația are un caracter universal, dar puterea sa scade rapid cu distanța, fiind cea mai slabă dintre cele patru forțe fundamentale ale fizicii. După descrierea gravitației de către Newton ca forță, relativitatea generală consideră că gravitația este o consecință a curburii spațiu-timpului datorită distribuției maselor. Conform teoriei actuale principale, (...)

  13. Singularități gravitaționale.Nicolae Sfetcu - manuscript
    Singularitățile gravitaționale în relativitatea generală sunt locații în spațiu-timp unde câmpul gravitațional devine infinit. Curburile invariabile scalare ale spațiu-timpului includ o măsură a densității materiei. Unii fizicieni și filosofi consideră că, deoarece densitatea materiei tinde spre infinit în singularitate, legile spațiu-timpului nu mai sunt valabile acolo. O singularitățile gravitațională aproape unanim acceptată în astrofizică și cosmologie, ca cea mai timpurie stare a universului, este Big Bang. Nici în acest caz legile cunoscute ale fizicii nu mai sunt valabile. DOI: 10.13140/RG.2.2.27271.75681.

Deșii unii fizicieni consideră că singularitățile indică un eșec al relativității generale, alții cred că singularitățile deschid în fapt un orizont nou în cosmologie, cu fenomene fizice reale care pot ajuta la un progres profund în înțelegerea noastră a lumii.

    Non-invasive Prenatal Testing (NIPT): Does the Practice Discriminate against Persons with Disabilities?Annette Dufner - 2021 - Journal of Perinatal Medicine 49 (8):945-948.
    The most well-known goal of non-invasive prenatal testing (NIPT) is still to determine whether or not a fetus has trisomy 21. Since women often terminate the pregnancy upon a positive result, there is concern that the use of NIPT contributes to discrimination against persons with disabilities. If this concern is justified, it could have an impact on the wider social acceptability of existing testing practices and their potential further expansion. This paper demonstrates four different versions of the discrimination worry, indicates (...)

    The Turing Test (TT), the Chinese Room Argument (CRA), and the Symbol Grounding Problem (SGP) are about the question “can machines think?” We propose to look at these approaches to Artificial Intelligence (AI) by showing that they all address the possibility for Artificial Agents (AAs) to generate meaningful information (meanings) as we humans do. The initial question about thinking machines is then reformulated into “can AAs generate meanings like humans do?” We correspondingly present the TT, the CRA and the SGP (...)

    Genetic testing in the workplace is a technology both full of promise and fraught with ethical peril. Though not yet common, it is likely to become increasingly so. We survey the key arguments in favour of such testing, along with the most significant ethical worries. We further propose a set of pragmatic criteria, which, if met, would make it permissible for employers to offer (but not to require) workplace genetic testing.

However, the repercussions of information asymmetry are thought to be more substantial in the stock market. Because, in addition to measurable economic impact, knowledge asymmetry harms trust. The Vietnamese stock market has experienced several successes since its creation, yet it still has many restrictions typical of a young market.

    Apparently, I’m a righteous son of a bitch, morally speaking. At least that’s the conclusion I would have to reach if I trusted the results of a morality test I took at the BBC website (bbc.co.uk/labuk/experiments/morality). The test was devised to collect data for a “new theory” that seeks to make sense of human morality in terms of a super-organism concept. Briefly, the idea is that “we, as individuals, behave as if we are part of a bigger ‘superorganism’ when we (...)

    -/- For all that digital methods—including network visualization, text analysis, and others—have begun to show extensive promise in philosophical contexts, a tension remains between two uses of those tools that have often been taken to be incompatible, or at least to engage in a kind of trade-off: the discovery of new hypotheses and the testing of already-formulated positions. This paper presents this basic distinction, then explores ways to resolve this tension with the help of two interdisciplinary case studies, taken from (...)

    A new Evidence Test is applied to the problem of testing whether two Poisson random variables are dependent. The dependence structure is that of Holgate’s bivariate distribution. These bivariate distribution depends on three parameters, 0 < theta_1, theta_2 < infty, and 0 < theta_3 < min(theta_1, theta_2). The Evidence Test was originally developed as a Bayesian test, but in the present paper it is compared to the best known test of the hypothesis of independence in a frequentist framework. It is (...)

    Preregistration has been proposed as a useful method for making a publicly verifiable distinction between confirmatory hypothesis tests, which involve planned tests of ante hoc hypotheses, and exploratory hypothesis tests, which involve unplanned tests of post hoc hypotheses. This distinction is thought to be important because it has been proposed that confirmatory hypothesis tests provide more compelling results (less uncertain, less tentative, less open to bias) than exploratory hypothesis tests.

The two tests can yield different results; it is the first, neglected test that provides the more appropriate indication of intelligence. (...)

  36. Inconsistent multiple testing corrections: The fallacy of using family-based error rates to make inferences about individual hypotheses.Mark Rubin - 2024 - Methods in Psychology 10.
    During multiple testing, researchers often adjust their alpha level to control the familywise error rate for a statistical inference about a joint union alternative hypothesis (e.g., “H1,1 or H1,2”). However, in some cases, they do not make this inference. Instead, they make separate inferences about each of the individual hypotheses that comprise the joint hypothesis (e.g., H1,1 and H1,2). For example, a researcher might use a Bonferroni correction to adjust their alpha level from the conventional level of 0.050 to 0.025 (...)

    We address the ethics of scenarios in which one party entraps, intentionally tempts or intentionally tests the virtue of another. We classify, in a new manner, three distinct types of acts that are of concern, namely acts of entrapment, of intentional temptation and of virtue testing. Our classification is, for each kind of scenario, of itself neutral concerning the question whether the agent acts permissibly. We explain why acts of entrapment are more ethically objectionable than like acts of intentional temptation (...)

    The observational-theoretical distinction has played a central role in the philosophy of science from logical empiricism onwards. Developments within the discipline have shown that such a distinction hides two non-identical distinctions: observational vs. non-observational and theoretical vs. non-theoretical. Likewise, metatheoretical structuralism proposed a more sophisticated treatment of theoricity in terms of the operational dependence or independence of concepts from the theories in which they appear. Despite this remarkable sophistication, it is still generally accepted that the distinction between theoretical and non-theoretical (...)

  42. Genetic Testing for Sale: Implications of Commercial Brca Testing in Canada.Bryn Williams-Jones - 2002 - Dissertation, The University of British Columbia (Canada)
    Ongoing research in the fields of genetics and biotechnology hold the promise of improved diagnosis and treatment of genetic diseases, and potentially the development of individually tailored pharmaceuticals and gene therapies. Difficulty, however, arises in determining how these services are to be evaluated and integrated equitably into public health care systems such as Canada's. The current context is one of increasing fiscal restraint on the part of governments, limited financial resources being dedicated to health care, and rising costs for new (...)

  43. Bayesian Evidence Test for Precise Hypotheses.Julio Michael Stern - 2003 - Journal of Statistical Planning and Inference 117 (2):185-198.
    The full Bayesian signi/cance test (FBST) for precise hypotheses is presented, with some illustrative applications. In the FBST we compute the evidence against the precise hypothesis. We discuss some of the theoretical properties of the FBST, and provide an invariant formulation for coordinate transformations, provided a reference density has been established. This evidence is the probability of the highest relative surprise set, “tangential” to the sub-manifold (of the parameter space) that defines the null hypothesis.

  44. Tests and Anomalies of Post-Newtonian Gravitational Theories.Nicolae Sfetcu - manuscript
    Usually, the "laboratory" of gravitational tests was the celestial bodies, the astrophysical systems. But such tests are disturbed by non-gravitational effects. The most used such "laboratory" was the solar system. Recently, scientists have focused on observing binary pulsars for the verification of gravitational theories, by observing the variations of the orbital period, thus providing indirect evidence for the emission of gravitational radiation. But the experimenter cannot "arrange the lab" according to his needs, nor trigger certain events when he needs them. (...)

  46. Hypothesis Testing, “Dutch Book” Arguments, and Risk.Daniel Malinsky - 2015 - Philosophy of Science 82 (5):917-929.
    “Dutch Book” arguments and references to gambling theorems are typical in the debate between Bayesians and scientists committed to “classical” statistical methods. These arguments have rarely convinced non-Bayesian scientists to abandon certain conventional practices, partially because many scientists feel that gambling theorems have little relevance to their research activities. In other words, scientists “don’t bet.” This article examines one attempt, by Schervish, Seidenfeld, and Kadane, to progress beyond such apparent stalemates by connecting “Dutch Book”–type mathematical results with principles actually endorsed (...)

  47. On Testing the Simulation Theory.Tom Campbell, Houman Owhadi, Joe Savageau & David Watkinson - manuscript
    Can the theory that reality is a simulation be tested? We investigate this question based on the assumption that if the system performing the simulation is nite (i.e. has limited resources), then to achieve low computational complexity, such a system would, as in a video game, render content (reality) only at the moment that information becomes available for observation by a player and not at the moment of detection by a machine (that would be part of the simulation and whose (...)

  48. Analyzing the Effects of Changes in Testing Methods on Evidenced Teaching Competencies.Cyrus Casingal - 2024 - Education Digest 19 (1):25-33.
    There is a critical need to understand the effect of changing assessment methods on demonstrated competencies in teacher education. This study examined how the transition from online to in-person testing affects the measured teaching competencies of students who completed a Competency-Based Enhancement (CBE) program, aiming to identify factors contributing to performance differences and strategies for adaptation. Using a one-group pre-test-post-test design, the study involved 669 graduating teacher education students at Pangasinan State University. Participants completed online pre-tests and in-person post-tests, with (...)

  49. Adversarial Sampling for Fairness Testing in Deep Neural Network.Tosin Ige, William Marfo, Justin Tonkinson, Sikiru Adewale & Bolanle Hafiz Matti - 2023 - International Journal of Advanced Computer Science and Applications 14 (2).
    In this research, we focus on the usage of adversarial sampling to test for the fairness in the prediction of deep neural network model across different classes of image in a given dataset. While several framework had been proposed to ensure robustness of machine learning model against adversarial attack, some of which includes adversarial training algorithm. There is still the pitfall that adversarial training algorithm tends to cause disparity in accuracy and robustness among different group. Our research is aimed at (...)

  50. Chi-square test for imprecise data in consistency table.Muhammad Aslam & Florentin Smarandache - 2023 - Frontiers in Applied Mathematics and Statistics 9.
    In this paper, we propose the introduction of a neutrosophic chi-square-test for consistency, incorporating neutrosophic statistics. Our aim is to modify the existing chi-square -test for consistency in order to analyze imprecise data. We present a novel test statistic for the neutrosophic chi-square -test for consistency, which accounts for the uncertainties inherent in the data. To evaluate the performance of the proposed test, we compare it with the traditional chi-square -test for consistency based on classical statistics. By conducting a comparative (...)
