Generation planning approaches face challenges in managing the incompatible mathematical structures between stochastic production simulations for reliability assessment and optimization models for generation planning, which hinders the integration of reliability constraints. This study proposes an approach to embedding reliability verification constraints into generation expansion planning by leveraging a weighted oblique decision tree (WODT) technique. For each planning year, a generation mix dataset, labeled with reliability assessment simulations, is generated. An WODT model is trained using this dataset. Reliability-feasible regions are extracted via depth-first search technique and formulated as disjunctive constraints. These constraints are then transformed into mixed-integer linear form using a convex hull modeling technique and embedded into a unit commitment-integrated generation expansion planning model. The proposed approach is validated through a long-term generation planning case study for the Electric Reliability Council of Texas (ERCOT) region, demonstrating its effectiveness in achieving reliable and optimal planning solutions.

Early diagnosis of Alzheimer's Disease (AD) faces multiple data-related challenges, including high variability in patient data, limited access to specialized diagnostic tests, and overreliance on single-type indicators. These challenges are exacerbated by the progressive nature of AD, where subtle pathophysiological changes often precede clinical symptoms by decades. To address these limitations, this study proposes a novel approach that takes advantage of routinely collected general laboratory test histories for the early detection and differential diagnosis of AD. By modeling lab test sequences as "sentences", we apply word embedding techniques to capture latent relationships between tests and employ deep time series models, including long-short-term memory (LSTM) and Transformer networks, to model temporal patterns in patient records. Experimental results demonstrate that our approach improves diagnostic accuracy and enables scalable and costeffective AD screening in diverse clinical settings.
Non-Markovian stochastic processes are ubiquitous in biology. Nevertheless, we lack a general framework for quantifying historical dependencies. In this Letter, we propose an information-theoretic approach to decompose history dependence in systems with non-Markovian dynamics, quantifying the information encoded in dependencies of each order. In minimal models of non-Markovian dynamics, we show that this framework correctly captures the underlying historical dependencies, even when autocorrelations do not. In prolonged recordings of fly behavior, we find that the scaling of non-Markovian dependencies is invariant across timescales from fractions of a second to minutes. Despite this invariance, the overall amount of non-Markovian information is non-monotonic, suggesting a unique timescale on which historical dependencies are strongest.
Utilizing Spencer-Oatey’s Rapport Management Theory, this study examines both self-praise and self-denigration used by young people on social media platforms in Jordan. The study aimed to identify self-praise and self-denigration strategies, their roles in rapport management, and their impact on gender roles. The data consist of 359 posts and comments collected from different social media networks, such as Facebook, Instagram, and Twitter. Findings reveal three major self-praise strategies, ranked in order of frequency: self-praising for belonging, self-praising for personality and skills and self-praising for appearance. Conversely, self-denigration is mainly categorized into two strategies comprising self-denigrating for skills and self-denigrating for appearance, arranged by prevalence. These strategies illustrate different aspects of rapport management including face, sociality rights and interactional goals. This indicates how young people regulate self-expression for cultural acceptance and social rapport. The interplay between self-disclosures and cultural norms is particularly evident regarding expectations about gender roles in Jordan.

The thermal and magnetic histories of planetesimals provide unique insights into the formation and evolution of Earth's building blocks. These histories can be gleaned from meteorites by using numerical models to translate measured properties into planetesimal behaviour. In this paper, we present a new 1D planetesimal thermal evolution and dynamo generation model. This magnetic field generation model is the first of a differentiated, mantled planetesimal that includes both mantle convection and non-eutectic core solidification. We have improved fundamental aspects of mantle heat transport by including a more detailed viscosity model and stagnant lid convection parametrisations consistent with internal heating. We have also added radiogenic heating from $^{60}Fe$ in the metallic Fe-FeS core. Additionally, we implement a combined thermal and compositional buoyancy flux, as well as the latest magnetic field scaling laws to predict magnetic field strengths during the planetesimal's thermal evolution until core solidification is complete. We illustrate the consequences of our model changes with an example run for a 500 km radius planetesimal. These effects include more rapid erosion of core thermal stratification and longer duration of mantle convection compared to previous studies. The additional buoyancy from core solidification has a marginal effect on dynamo strength, but for some initial core sulfur contents it can prevent cessation of the dynamo when mantle convection ends. Our model can be used to investigate the effects of individual parameters on dynamo generation and constrain properties of specific meteorite parent bodies. Combined, these updates mean this model can predict the most reliable and complete magnetic field history for a planetesimal to date, so is a valuable tool for deciphering planetesimal behaviour from meteorite properties.
In the last few decades, the European Union (EU) has developed a comprehensive approach to natural
disaster management, with a particular focus on civil protection laws and international cooperation. The EU
acknowledges the importance of proactive measures to minimize the impact of potential crises, namely in the
context of climate change, in response of the increasing complexity and frequency of climate-induced disasters.
This study analyses and discusses EU humanitarian legislation that aims to promote disaster resilience in
member states. It starts with an overview of the EU’s legal framework, continuing with an analysis of the different
types of secondary legislation in the Union, distinguishing their purposes and respective attributes, and then
delves into the already established bases for preventing and mitigating the impacts of natural disasters and the
frequency of such risks. Finally, a critical reflection is made on the strengths and limitations of the legal basis
established by the EU.

This article is based on the content analysis of the Polish Facebook group Nauczyciele historii (“History Teachers”) which is administered by, and addressed to, practicing and prospective history teachers. The group’s over six thousand members engage and interact by writing, reading, reacting to, and commenting via as many as twenty plus posts daily. We examined the group’s on-line discussions for manifestations of the member-teachers’ epistemic considerations: their reasoning about the epistemic nature of history; their assumptions regarding the goals and meaning of history as a school subject; and their attitudes toward the narratives of difference, diversity, and multi-perspectivism. Our findings reveal that Polish history teachers’ epistemology is poorly conceptualized, rather naïve, and largely unaffected by the developments in historical and didactical theories of the last 50 years. Those teachers do not reflect on the epistemic nature of history. They approach history as a “science”, which they presume to be objective and unambiguous. They tend to see themselves as transmitters of knowledge about the past which their pupils should internalize, and as propagators of those “patriotic” values that - according to certain received, long-established discourses - strengthen national identity and social cohesion.
To understand the evolution of the Moon, we numerically modeled mantle convection and magmatism in a two-dimensional polar rectangular mantle. Magmatism occurs as an upward permeable flow of magma generated by decompression melting through the convecting matrix. The mantle is assumed to be initially enriched in heat-producing elements (HPEs) and compositionally dense ilmenite-bearing cumulates (IBC) at its base. Here, we newly show that magma generation and migration play a crucial role in the calculated volcanic and radial expansion/contraction history. Magma is generated in the deep mantle by internal heating for the first several hundred million years. A large volume of the generated magma ascends to the surface as partially molten fingers and plumes driven by melt-buoyancy to cause a volcanic activity and radial expansion of the planet with the peak at 3.5-4 Gyr ago. Eventually, however, the planet begins to radially contract when the mantle solidifies by cooling from the surface boundary. As the mantle is cooled, the activity of partially molten plumes declines but continues for billions of years after the peak because some basal materials enriched in the dense IBC components hold HPEs. The calculated volcanic and radial expansion/contraction history is consistent with the observed history of the Moon. Our simulations suggest a substantial fraction of the mantle was solid, and there was a basal layer enriched in HPEs and the IBC components at the beginning of the history of the Moon.
The purpose of this brief article is to clarify certain distortions of the history of ideas about the quantum theory of de Sitter space that have appeared in recent literature.
The consumption of chocolate in Europe serves as a way to observe the flow of Mesoamerican culture into Europe. Cacao and chocolate played a central role in Mesoamerican society as it was used for rituals, tribute, and consumption. The interest in consuming chocolate gained a foothold only after a significant population within Spain had experienced chocolate in Mesoamerica, but then quickly spread through the rest of Europe. The diffusion of chocolate consumption across Europe retained elements of Mesoamerican culture that left a lasting impact. Cacao and chocolate ultimately remain products of Mesoamerican culture, while European contact leveraged the mystical properties, mimicking and hijacking indigenous beliefs and manifesting in different shapes within European society.
Abstract Background Ingestion of fish bones leading to gastric perforation and inducing abscess formation in the caudate lobe of the liver is very rare. Case presentation A 67-year-old man presented to our hospital with a 2-day history of subxiphoid pain. There were no specific symptoms other than pain. Laboratory tests showed only an increase in the number and percentage of neutrophils. Contrast-enhanced Computerized tomography (CT) of the abdomen showed two linear dense opacities in the gastric cardia, one of which penetrated the stomach and was adjacent to the caudate lobe of the liver, with inflammatory changes in the caudate lobe. We finally diagnosed his condition as a caudate lobe abscess secondary to intestinal perforation caused by a fishbone based on the history and imaging findings. The patient underwent 3D laparoscopic partial caudate lobectomy, incision and drainage of the liver abscess, and fishbone removal. The procedure was successful and we removed the fishbone from the liver. The patient was discharged on the 9th postoperative day without other complications. Conclusions Liver abscess caused by foreign bodies requires multidisciplinary treatment. Especially when located in the caudate lobe, we must detect and remove the cause of the abscess as early as possible. Foreign bodies that perforate the gastrointestinal tract can penetrate to the liver and cause abscess formation, as in this case. When exploring the etiology of liver abscesses, we should investigate the general condition, including the whole gastrointestinal tract.
Since the founding of the Heydar Aliyev Foundation in 2004, this institution has been actively involved in large-scale international cultural relations. The purpose of creating this fund was to preserve and popularize the legacy of the national leader of the Azerbaijani people, Heydar Aliyev, to convey the truth about Azerbaijan to the world community, and to familiarize with its history, culture, and spiritual values. The purpose of this article is to determine the stages of formation and development of the Heydar Aliyev Foundation, to analyze the directions of its multi-vector activity and to justify the role of the Foundation in forming a positive image of independent Azerbaijan. Along with general logical methods, the methods of political monitoring, content analysis, historical and comparative analysis are used, which make it possible to highlight the complex of activities carried out by the Fund and to forecast the trends of its further activity. Since the foundation of the Foundation, important projects have been developed and successfully implemented to protect the welfare of the Azerbaijani people, protect their national heritage and moral values. The Heydar Aliyev Foundation, paying special attention to the expansion of cooperation with Islamic countries in the field of science and culture, ensured the achievement of the highest level of development of relations between Azerbaijan and the Islamic Organization for Education, Science and Culture. The Heydar Aliyev Foundation paid serious attention to the expansion of cooperation within the framework of the UN, which resulted in the adoption of the Program on creating conditions for the use of information and communication technologies by people with visual impairments. According to the results of the research, it was established that the Heydar Aliyev Foundation, in cooperation with the government, parliament and the Ministry of Foreign Affairs, plays the role of one of the effective means of implementing the foreign policy, social, humanitarian, political, economic and cultural strategy of Azerbaijan. The Foundation was able to form a positive image of Azerbaijan on an international scale, establishing constructive cooperation in all spheres, both with individual states and with influential international and regional organizations.

BackgroundMalignancies, especially lymphoma, are a common cause of adult secondary HLH and an independent risk factor for the prognosis of HLH patients.MethodsPatients with lymphoma alone or concurrent lymphoma-associated phagocytic syndrome (LAHS) admitted to Beijing Friendship Hospital from January 2016 to December 2020 were enrolled in this study.FindingsThere were 348 lymphoma patients, 104 concurrent with LAHS. The pathological type of lymphoma without LAHS was dominated by B-cell lymphoma, while those with LAHS were T/NK-cell lymphoma predominantly (p < 0.001). Superficial lymph node enlargement was more significant in patients with B-LAHS (p = 0.006), while patients with T/NK-LAHS had lower neutrophil counts (p = 0.005), lower fibrinogen levels (p < 0.001), higher transaminase levels, and more co-infection with EBV (p < 0.001). B-LAHS had significantly higher IL-10 levels than with T/NK-LAHS (p = 0.006), and NK/T-LAHS had significantly higher IP-10 levels than other T-LAHS (p = 0.008). Age, platelet count, IPI, history of NK/T lymphoma, and no remission of HLH were independent risk factors for prognosis in patients with non-Hodgkin lymphoma-associated phagocytic syndrome (NHL-LAHS), and a prognostic risk score model for NHL-LAHS was developed.ConclusionLAHS is a life-threatening disease with a poor prognosis. The prognostic risk score model for NHL-LAHS with a good fit and validation for the test has value for clinical application.

The article analyzes the cooperation of UN structures with religious non-governmental organizations, as well as with faith-based communities. The authors consider diff erent levels of the infl uence of the religious factor on the UN activity, and also articulate new directions of its development, outlined during the COVID-19 period. The authors focus on the latent semantic and structural confl ict nature of the global agenda, which is formulated by elites who recognize the “benefi ts” of religious institutions and seek to use the possibilities of religious networks, on the one hand. On the other hand, they point to internal disagreements characteristic of national religious communities, which, as a result of their participation in international dialogue, bring additional tension both to global discussions and to the internal processes of their countries. Global health, which has become an important part of international relations, puts on the agenda the search for a new ethic of global dialogue, of which religious values and religious actors are becoming a part. In the COVID-19 pandemic, trends have emerged that have made the role of religion more visible in the current global health and bioethics agenda. First of all, in connection with the threats of a global pandemic, the need to create new forms of global health management and response to epidemic threats, as well as the organization of a system of “assistance” to developing countries in the fi eld of public health.
The spread of infectious disease in a human community or the proliferation of fake news on social media can be modeled as a randomly growing tree-shaped graph. The history of the random growth process is often unobserved but contains important information such as the source of the infection. We consider the problem of statistical inference on aspects of the latent history using only a single snapshot of the final tree. Our approach is to apply random labels to the observed unlabeled tree and analyze the resulting distribution of the growth process, conditional on the final outcome. We show that this conditional distribution is tractable under a shape-exchangeability condition, which we introduce here, and that this condition is satisfied for many popular models for randomly growing trees such as uniform attachment, linear preferential attachment and uniform attachment on a $D$-regular tree. For inference of the root under shape-exchangeability, we propose O(n log n) time algorithms for constructing confidence sets with valid frequentist coverage as well as bounds on the expected size of the confidence sets. We also provide efficient sampling algorithms that extend our methods to a wide class of inference problems.
There are available by now many arguments concerning the intrinsic and endemic value of the humanities, and both from a medievalist and a modernist perspective. Similarly, there continue to be many critics who would not mind the elimination of the humanities and argue vociferously for this goal. Every critical investigation of how to defend our field thus proves to be highly valuable, but we in the humanities must also develop specific points concerning the importance of our research that will convince both students, parents, administrators, and politicians in concrete, pragmatic terms regarding the supreme relevance of college education. Fortunately, the current COVID-19 crisis has also profiled in a dramatic fashion what proves to be of fundamental importance for human life, both past and present, reminding us of the critical importance of the humanities. An existence without virtues, a completely narcissistic or egoistical concept of life, or a society entirely predicated on materialistic interests would cut us off from our own future. This article discusses several literary works and also a modern movie in which the constant quest for meaning and relevance in our lives comes to the fore and gives us direction and understanding.
