Background The utility of estimated glomerular filtration rate (eGFR) and albuminuria for cardiovascular prediction is controversial. Methods We meta-analyzed individual-level data from 24 cohorts (with a median follow-up time longer than 4 years, varying from 4.2 to 19.0 years) in the Chronic Kidney Disease Prognosis Consortium (637,315 participants without a history of cardiovascular disease) and assessed C-statistic difference and reclassification improvement for cardiovascular mortality and fatal and non-fatal cases of coronary heart disease, stroke, and heart failure in 5-year timeframe, contrasting prediction models consisting of traditional risk factors with and without creatinine-based eGFR and/or albuminuria (either albumin-to-creatinine ratio [ACR] or semi-quantitative dipstick proteinuria). Findings The addition of eGFR and ACR significantly improved the discrimination of cardiovascular outcomes beyond traditional risk factors in general populations, but the improvement was greater with ACR than with eGFR and more evident for cardiovascular mortality (c-statistic difference 0.0139 [95%CI 0.0105–0.0174] and 0.0065 [0.0042–0.0088], respectively) and heart failure (0.0196 [0.0108–0.0284] and 0.0109 [0.0059–0.0159]) than for coronary disease (0.0048 [0.0029–0.0067] and 0.0036 [0.0019–0.0054]) and stroke (0.0105 [0.0058–0.0151] and 0.0036 [0.0004–0.0069]). Dipstick proteinuria demonstrated smaller improvement than ACR. The discrimination improvement with kidney measures was especially evident in individuals with diabetes or hypertension but remained significant with ACR for cardiovascular mortality and heart failure in those without either of these conditions. In participants with chronic kidney disease (CKD), the combination of eGFR and ACR for risk discrimination outperformed most single traditional predictors; the c-statistic for cardiovascular mortality declined by 0.023 [0.016–0.030] vs. <0.007 when omitting eGFR and ACR vs. any single modifiable traditional predictors, respectively. Interpretation Creatinine-based eGFR and albuminuria should be taken into account for cardiovascular prediction, especially when they are already assessed for clinical purpose and/or cardiovascular mortality and heart failure are the outcomes of interest (e.g., the European guidelines on cardiovascular prevention). ACR may have particularly broad implications for cardiovascular prediction. In CKD populations, the simultaneous assessment of eGFR and ACR will facilitate improved cardiovascular risk classification, supporting current CKD guidelines.

In the 1960s and 1970s a series of observations and theoretical developments highlighted the presence of several anomalies which could, in principle, be explained by postulating one of the following two working hypotheses: (i) the existence of dark matter, or (ii) the modification of standard gravitational dynamics in low accelerations. In the years that followed, the dark matter hypothesis as an explanation for dark matter phenomenology attracted far more attention compared to the hypothesis of modified gravity, and the latter is largely regarded today as a non-viable alternative. The present article takes an integrated history and philosophy of science approach in order to identify the reasons why the scientific community mainly pursued the dark matter hypothesis in the years that followed, as opposed to modified gravity. A plausible answer is given in terms of three epistemic criteria for the pursuitworthiness of a hypothesis: (a) its problem-solving potential, (b) its compatibility with established theories and the feasibility of incorporation, and (c) its independent testability. A further comparison between the problem of dark matter and the problem of dark energy is also presented, explaining why in the latter case the situation is different, and modified gravity is still considered a viable possibility.

The integration of the history and philosophy of statistics was initiated at least by Hacking (1975) and advanced by Hacking (1990), Mayo (1996), and Zabell (2005), but it has not received sustained follow-up. Yet such integration is more urgent than ever, as the recent success of artificial intelligence has been driven largely by machine learning -- a field historically developed alongside statistics. Today, the boundary between statistics and machine learning is increasingly blurred. What we now need is integration, twice over: of history and philosophy, and of two fields they engage -- statistics and machine learning. I present a case study of a philosophical idea in machine learning (and in formal epistemology) whose root can be traced back to an often under-appreciated insight in Neyman and Pearson's 1936 work (a follow-up to their 1933 classic). This leads to the articulation of an epistemological principle -- largely implicit in, but shared by, the practices of frequentist statistics and machine learning -- which I call achievabilism: the thesis that the correct standard for assessing non-deductive inference methods should not be fixed, but should instead be sensitive to what is achievable in specific problem contexts. Another integration also emerges at the level of methodology, combining two ends of the philosophy of science spectrum: history and philosophy of science on the one hand, and formal epistemology on the other hand.

A history-independent data structure does not reveal the history of operations applied to it, only its current logical state, even if its internal state is examined. This paper studies history-independent concurrent dictionaries, in particular, hash tables, and establishes inherent bounds on their space requirements. This paper shows that there is a lock-free history-independent concurrent hash table, in which each memory cell stores two elements and two bits, based on Robin Hood hashing. Our implementation is linearizable, and uses the shared memory primitive LL/SC. The expected amortized step complexity of the hash table is $O(c)$, where $c$ is an upper bound on the number of concurrent operations that access the same element, assuming the hash table is not overpopulated. We complement this positive result by showing that even if we have only two concurrent processes, no history-independent concurrent dictionary that supports sets of any size, with wait-free membership queries and obstruction-free insertions and deletions, can store only two elements of the set and a constant number of bits in each memory cell. This holds even if the step complexity of operations on the dictionary is unbounded.

This article examines foreign direct investment (FDI) as an indicator of economic integration, focusing on Central and Eastern Europe (CEE) in the two decades they have been EU members. Although CEE countries have remained on the EU’s periphery and struggled with development gaps, they have attracted substantial FDI, especially in the first decade after accession, fuelling the growth of outward FDI and integration into global value chains. Despite CEE economies like Slovenia and Hungary having seen differences in their use of FDI, such investment and European integration will remain central to the region’s economic development, even amid the ongoing geopolitical tensions.

Primordial gravitational waves propagate almost unimpeded from the moment they are generated to the present epoch. Nevertheless, they are subject to convolution with a non-trivial transfer function. Within the standard thermal history, shifts in the temperature-redshift relation combine with damping effects by free streaming neutrinos to non-trivially process different wavelengths during radiation domination, with subsequently negligible effects at later times. Presuming a nearly scale invariant primordial spectrum, one obtains a characteristic late time spectrum, deviations from which would indicate departures from the standard thermal history. Given the paucity of probes of the early universe physics before nucleosynthesis, it is useful to classify how deviations from the standard thermal history of the early universe can be constrained from observations of the late time stochastic background. The late time spectral density has a plateau at high frequencies that can in principle be significantly enhanced or suppressed relative to the standard thermal history depending on the equation of state of the epoch intervening reheating and the terminal phase of radiation domination, imprinting additional features from bursts of entropy production, and additional damping at intermediate scales via anisotropic stress production. In this paper, we survey phenomenologically motivated scenarios of early matter domination, kination, and late time decaying particles as representative non-standard thermal histories, elaborate on their late time stochastic background, and discuss constraints on different model scenarios.

A collective trauma established in the cultural memory can function as a unifier of the in-group for a long time. The objective of this article is to clarify how April 9, 1989 and 1991, the Tbilisi War and civil confrontation, and a stressful series of sudden and intensive changes are analyzed, conceptualized, and interpreted in the fiction and memoirs created after Georgia became independent, to what extent the use of the notions of trauma and triumph are appropriate for Georgia, and whether the reality of the 1990s can be assessed as the trauma of victory. We believe that fiction and memoirs play a major role in constructing an event as a cultural trauma. On the one hand, literary texts determine the meaning of an event and shape it as a trauma and on the other hand, narration is an important method for overcoming a trauma. A trauma can be overcome through constantly conceptualizing and analyzing it, not through repression and hushing.

Los museos de Historia Natural en Chile han sido objeto creciente de interés histórico al tratarse de instituciones estrechamente vinculadas a la formación del estado-nación y protagonistas de la configuración de una cultura científica en el país. En las últimas décadas, su historia se ha abordado desde diversos enfoques. Las nuevas aproximaciones historiográficas van dejando atrás, de manera gradual, una historia fuertemente relacionada con el surgimiento del Estado decimonónico, donde se imponen los ideales «progresistas», para avanzar hacia nuevas miradas que amplían su foco hacia las influencias del desarrollo científico del siglo XVIII, así como hacia el valor de los intercambios y redes globales del siglo XIX, enfatizando especialmente los intereses y motivaciones de las personas que construyeron estos espacios. Consideramos, por tanto, el arco temporal que comprende desde el siglo XVIII ilustrado hasta comienzos del siglo XX, caracterizado por una mayor especialización científica que trasciende a la clasificación taxonómica de la naturaleza y se enfoca en comprender el cambio y la relación filogenética entre especies como proceso evolutivo. De este modo, abordaremos a través de un análisis principalmente historiográfico, la manera en que se ha ido construyendo la historia de las colecciones y de los museos de historia natural en Chile, enfatizando en las redes sociales de múltiples actores, que contribuyeron a su conformación, desarrollo y difusión.

We present the results of processing the effects of the powerful Gamma Ray Burst GRB221009A captured by the charged particle detectors (electrostatic analyzers and solid-state detectors) onboard spacecraft at different points in the heliosphere on October 9, 2022. To follow the GRB221009A propagation through the heliosphere we used the electron and proton flux measurements from solar missions Solar Orbiter and STEREO-A; Earth magnetosphere and the solar wind missions THEMIS and Wind; meteorological satellites POES15, POES19, MetOp3; and MAVEN - a NASA mission orbiting Mars. GRB221009A had a structure of four bursts: less intense Pulse 1 - the triggering impulse - was detected by gamma-ray observatories at 131659 UT (near the Earth); the most intense Pulses 2 and 3 were detected on board all the spacecraft from the list, and Pulse 4 detected in more than 500 s after Pulse 1. Due to their different scientific objectives, the spacecraft, which data was used in this study, were separated by more than 1 AU (Solar Orbiter and MAVEN). This enabled tracking GRB221009A as it was propagating across the heliosphere. STEREO-A was the first to register Pulse 2 and 3 of the GRB, almost 100 seconds before their detection by spacecraft in the vicinity of Earth. MAVEN detected GRB221009A Pulses 2, 3, and 4 at the orbit of Mars about 237 seconds after their detection near Earth. By processing the time delays observed we show that the source location of the GRB221009A was at RA 288.5 degrees, Dec 18.5 degrees (J2000) with an error cone of 2 degrees

The study aims to identify peculiarities of sociocultural adaptation (factors, coping strategies and anticipatory competence) of students from India, China and Arab countries. The research is based on the data obtained from the first-, second- and third-year students from India (73 respondents), China (45 respondents), Arab countries (64 respondents). The “Russian language proficiency” factor shows more significance for students from India and China, compared to students from Arab countries. Students from China, India and Arab countries tend to start and maintain relationships, to participate in academic activities, to have hobbies and interests and interact with other students. The prosocial coping strategy is predominant for Arab, Indian and Chinese students, regardless of their culture of origin, which proves  universality of the strategy. Representatives of a polychronic culture (students from Arab countries and India) lack temporal anticipatory competence,with Arab students showing the lowest value of this parameter. Chinese  students differ from representatives of a polyactive culture (Arab students) or a reactive-polyactive culture (Indian students) as they can hardly predict how a person they know would act in a certain situation.

RESUMEN: La novedad del fascismo y los cambios institucionales y políticos que se produjeron durante el régimen de Benito Mussolini (1922-1943) en Italia fueron seguidos con atención por los políticos, los empresarios y los intelectuales uruguayos desde fines de la década de 1920.  Como veremos en el presente texto, en la década de 1930 tuvieron origen distintos partidos, agrupaciones y publicaciones periódicas que aparecieron en la escena pública proclamando la instauración de un régimen corporativo o, al menos, la concreción de alguna forma de representación corporativa.

This issue marks the creation of a new section within JESHO entitled ‘From the Archives of Asian History.’ This section will feature seminal works in the history of Asia from the late Antique period to the 20th century, which were originally published in languages other than English, but which unfortunately have long been forgotten and therefore tend to be underappreciated, especially by a younger generation of scholars. There are many ways to explain the peculiar phenomenon of ground-breaking scholarship falling into desuetude; but it is ironic to observe that, while major digitization projects have been now underway for a decade or more, thereby impressing upon many the idea that everything is available on-line, academic conformism remains rampant, indeed unrestrained. Time and again must JESHO’s editors and readers alike lament how manuscripts submitted for consideration tend to reproduce often uncritically the prevailing current of thought, to privilege established views over works that today are less cited, and disregard earlier scholarship that in fact contributed significantly to the advancement of historiography. While modern scholarship takes pride in the global reach of its perspectives and analyses, and almost every social science discipline reinvents itself by adding the adjective ‘global’ to its conventional name, the scholars who practice in these disciplines increasingly rely almost exclusively on anglophone literature. At the same time, we all must take stock of enduring asymmetries between national systems of higher education, which fuel a general mistrust for scholarship produced in countries outside the Anglo-Saxon world. It is an unfortunate fact that a graduate student coming from the Global South seeking to secure funding in Europe or North America will need not just to demonstrate her originality, but also her commitment to engaging with scholarship published in English rather than in, say, Portuguese or Turkish. Finally, we should all pause to reflect on the disincentive effects on multilingualism originating from the sinking quality of public education. Until the 1990s, for an undergraduate to hone multiple linguistic skills was a prerequisite for admission into schools offering courses on the histories and literatures of Asia. Nowadays, by contrast, lecturers are expected to constrain their syllabi mainly to scholarship

This paper emphasizes the importance of a robot's ability to refer to its task history, especially when it executes a series of pick-and-place manipulations by following language instructions given one by one. The advantage of referring to the manipulation history can be categorized into two folds: (1) the language instructions omitting details but using expressions referring to the past can be interpreted, and (2) the visual information of objects occluded by previous manipulations can be inferred. For this, we introduce a history-dependent manipulation task which objective is to visually ground a series of language instructions for proper pick-and-place manipulations by referring to the past. We also suggest a relevant dataset and model which can be a baseline, and show that our model trained with the proposed dataset can also be applied to the real world based on the CycleGAN. Our dataset and code are publicly available on the project website: https://sites.google.com/view/history-dependent-manipulation.

Recently, there is an increasing interest in highlight detection research where the goal is to create a short duration video from a longer video by extracting its interesting moments. However, most existing methods ignore the fact that the definition of video highlight is highly subjective. Different users may have different preferences of highlight for the same input video. In this paper, we propose a simple yet effective framework that learns to adapt highlight detection to a user by exploiting the user's history in the form of highlights that the user has previously created. Our framework consists of two sub-networks: a fully temporal convolutional highlight detection network $H$ that predicts highlight for an input video and a history encoder network $M$ for user history. We introduce a newly designed temporal-adaptive instance normalization (T-AIN) layer to $H$ where the two sub-networks interact with each other. T-AIN has affine parameters that are predicted from $M$ based on the user history and is responsible for the user-adaptive signal to $H$. Extensive experiments on a large-scale dataset show that our framework can make more accurate and user-specific highlight predictions.

Software Reliability has just passed the 50-year milestone as a technical discipline along with Software Engineering. This paper traces the roots of Software Reliability Engineering (SRE) from its pre-software history to the beginnings of the field with the first software reliability model in 1967 through its maturation in the 1980s to the current challenges in proving application reliability on smartphones and in other areas. This history began as a thesis proposal for a History of Science research program and includes multiple previously unpublished interviews with founders of the field. The project evolved to also provide a survey of the development of SRE from notable prior histories and from citations of new work in the field including reliability applications to Agile Methods. This history concludes at the modern-day providing bookends in the theory, models, literature, and practice of Software Reliability Engineering from 1968 to 2018 and pointing towards new opportunities to deepen and broaden the field.
