Breast cancer remains a leading cause of cancer-related mortality worldwide. Longitudinal mammography risk prediction models improve multi-year breast cancer risk prediction based on prior screening exams. However, in real-world clinical practice, longitudinal histories are often incomplete, irregular, or unavailable due to missed screenings, first-time examinations, heterogeneous acquisition schedules, or archival constraints. The absence of prior exams degrades the performance of longitudinal risk models and limits their practical applicability. While substantial longitudinal history is available during training, prior exams are commonly absent at test time. In this paper, we address missing history at inference time and propose a longitudinal risk prediction method that uses mammography history as privileged information during training and distills its prognostic value into a student model that only requires the current exam at inference time. The key idea is a privileged multi-teacher distillation scheme with horizon-specific teachers: each teacher is trained on the full longitudinal history to specialize in one prediction horizon, while the student receives only a reconstructed history derived from the current exam. This allows the student to inherit horizon-dependent longitudinal risk cues without requiring prior screening exams at deployment. Our new Privileged History Distillation (PHD) method is validated on a large longitudinal mammography dataset with multi-year cancer outcomes, CSAW-CC, comparing full-history and no-history baselines to their distilled counterparts. Using time-dependent AUC across horizons, our privileged history distillation method markedly improves the performance of long-horizon prediction over no-history models and is comparable to that of full-history models, while using only the current exam at inference time.

This article presents the text of a neglected inscription from Skepsis in the Troad. Walther Judeich published a drawing of the text in 1898, but did not provide a text. Louis Robert recognised it to be an honorific decree for a phrourarch, but otherwise it has attracted very little interest. It is here proposed that a Seleucid regnal dating formula can be restored in lines 2-3 and a reference to ‘barbarians’, which here must refer to Galatians, can be restored in line 6. The inscription therefore provides evidence of the Galatian War directly affecting Skepsis and belongs to the small dossier of evidence for the impact of the Galatians on north-western Asia Minor c. 277-275. The Antiocheia festival at Skepsis, known from a decree dated c. 200 and thus traditionally thought to have been founded for Antiochus III, may in fact have been established in the aftermath of the Galatian War in honour of Antiochus I.

The article analyses Claudian’s Panegyric for Honorius’ Sixth Consulship, a poem celebrating the end of the conflicts that troubled the Western Roman Empire, and particularly Gildo’s rebellion and the war against the Goths. This study examines how Claudian presents an image of restored peace despite ongoing troubles. The article explores the literary and stylistic techniques used to minimise violence and glorify Stilicho as the victorious general. It highlights the gap between poetic discourse and historical reality. Finally, it questions the political dimension of the panegyric and its role in imperial propaganda.

Background: The possibility that Alzheimer’s disease and related dementias (ADRD) is a modern disease arises from the minimal mention of advanced cognitive decline by ancient Greeks and Romans, who were mainly concerned with the physical frailties of older ages. Objective: Because standard medical histories of elderly health lacked mention of cognitive decline, we examined texts by Greek and Roman authors that mentioned memory loss and dementia. Methods: Primary texts of Greco-Roman authors, 8th century BCE into the 3rd century CE, that mentioned cognitive decline were identified and critically evaluated. Secondary sources were excluded. Results: No ancient account of cognitive loss is equivalent to modern clinical data. The term dementia was occasionally used in antiquity, but not invariably linked to old age. Ancient Greeks and Romans expected intellectual competence beyond age 60. While some memory loss was acknowledged, we found only four accounts of severe cognitive loss that might represent ADRD. The possibility of modest ADRD prevalence in ancient Greece and Rome is consistent with its low prevalence in the Tsimane of Bolivia. These contemporary Amerindians live under conditions of high mortality from frequent infections and minimal cardiovascular disease with physically demanding lives. Tsimane after age 60 had increased mild cognitive impairment; the few cases of dementia were not clinically consistent with AD. Conclusions: The modern ‘epidemic level’ of advanced dementias was not described among ancient Greco-Roman elderly. The possible emergence of advanced ADRD in the Roman era may be associated with environmental factors of air pollution and increased exposure to lead. Further historical analysis may formulate critical hypotheses about the modernity of high ADRD prevalence.

This paper offers a preliminary study of MS Atheniensis EBE 1089, a neglected lexicographic and grammatical miscellany consisting of several different sections, to be dated between the 13th and the 15th century. Among other texts, this manuscript transmits Phrynichus’ Eclogue and Moeris’ Lexicon. After providing a survey of the contents of this codex, the first part of the article deals with some of its main material features, with a description of its different sections and the scribes who copied them. Additionally, it is argued that the codex as a whole was the product of a single ‘editorial’ project carried out by a certain Μᾶρκος, active in the middle of the 16th century. The second part of the article offers a philological analysis of the folios containing the lexica of Phrynichus and Moeris; that gave the occasion to develop some new thoughts on their texts and manuscript traditions.

The paper re-examines the principal methodological questions, arising in the debate over the cosmological standard model's postulate of Dark Matter vs. rivalling proposals that modify standard (Newtonian and general-relativistic) gravitational theory, the so-called Modified Newtonian Dynamics (MOND) and its subsequent extensions. What to make of such seemingly radical challenges of cosmological orthodoxy? In the first part of our paper, we assess MONDian theories through the lens of key ideas of major 20th century philosophers of science (Popper, Kuhn, Lakatos, and Laudan), thereby rectifying widespread misconceptions and misapplications of these ideas common in the pertinent MOND-related literature. None of these classical methodological frameworks, which render precise and systematise the more intuitive judgements prevalent in the scientific community, yields a favourable verdict on MOND and its successors -- contrary to claims in the MOND-related literature by some of these theories' advocates; the respective theory appraisals are largely damning. Drawing on these insights, the paper's second part zooms in on the most common complaint about MONDian theories, their ad-hocness. We demonstrate how the recent coherentist model of ad-hocness captures, and fleshes out, the underlying -- but too often insufficiently articulated -- hunches underlying this critique. MONDian theories indeed come out as severely ad hoc: they do not cohere well with either theoretical or empirical-factual background knowledge. In fact, as our complementary comparison with the cosmological standard model's Dark Matter postulate shows, with respect to ad-hocness, MONDian theories fare worse than the cosmological standard model.

Some new, unlisted types of Samarian coins have appeared recently on the antiquities market. In the present paper I would like to discuss some points concerning one of them, which is especially interesting because of its iconography. The coin appeared on the market in Autumn 2021. Its reverse shows an image of a cavalryman with a spear or a javelin. Unlike the other images of the Iranian cavalrymen depicted on Samarian coins, the exemplar probably shows "the Great King like figure" having long beard and wearing a kidaris. So far, such an image is not only unique in Samarian coinage, but finds only one analogy in the coinages of the Achaemenid period in general. The image of "the Great King like figure" on horseback is, on the one hand, an interesting extension of the iconographic repertoire of Samarian coins, and on the other hand, it complements my earlier findings concerning the images of the Iranian horseman on Samarian, but also broadly speaking, on satrapal coins.

The real-world testing of decisions made using causal machine learning models is an essential prerequisite for their successful application. We focus on evaluating and improving contextual treatment assignment decisions: these are personalised treatments applied to e.g. customers, each with their own contextual information, with the aim of maximising a reward. In this paper we introduce a model-agnostic framework for gathering data to evaluate and improve contextual decision making through Bayesian Experimental Design. Specifically, our method is used for the data-efficient evaluation of the regret of past treatment assignments. Unlike approaches such as A/B testing, our method avoids assigning treatments that are known to be highly sub-optimal, whilst engaging in some exploration to gather pertinent information. We achieve this by introducing an information-based design objective, which we optimise end-to-end. Our method applies to discrete and continuous treatments. Comparing our information-theoretic approach to baselines in several simulation studies demonstrates the superior performance of our proposed approach.

In this work we probe the possibility of high-temperature conventional superconductivity in the boron-carbon system, using ab-initio screening. A database of 320 metastable structures with fixed composition (50$\%$/50$\%$) is generated with the Minima-Hopping method, and characterized with electronic and vibrational descriptors. Full electron-phonon calculations on sixteen representative structures allow to identify general trends in $T_{\textrm{c}}$ across and within the four families in the energy landscape, and to construct an approximate $T_{\textrm{c}}$ predictor, based on transparently interpretable and easily computable electronic and vibrational descriptors. Based on these, we estimate that around 10$\%$ of all metallic structures should exhibit $T_{\textrm{c}}$'s above 30 $K$. This work is a first step towards ab-initio design of new high-$T_{\textrm{c}}$ superconductors.

Is grief for the death of a loved one a universal, trans-historical emotion? What role does the historical, political and socio-cultural context play in how grief is understood, processed, performed, written about and represented in art? This special issue of thersites seeks to address these questions with reference to the cultures of ancient Greece and Rome. Drawing on a wide range of both textual and material culture evidence, the six papers that make up this issue investigate how the ancient Greeks and Romans reacted to the death of relatives, friends and members of their wider community, and how it affected their lives, societies and sense of identity. The first half of the issue is devoted to the portrayal of grief in the Homeric epics and Greek tragedy, while the second examines a rich variety of Roman evidence from inscriptions to art, literature and philosophy. Our work intersects with wider debates in the cross-disciplinary field of the History of Emotions, but some of the papers also reference recent scholarship on the senses in antiquity.

In graphs with rich texts, incorporating textual information with structural information would benefit constructing expressive graph embeddings. Among various graph embedding models, random walk (RW)-based is one of the most popular and successful groups. However, it is challenged by two issues when applied on graphs with rich texts: (i) sampling efficiency: deriving from the training objective of RW-based models (e.g., DeepWalk and node2vec), we show that RW-based models are likely to generate large amounts of redundant training samples due to three main drawbacks. (ii) text utilization: these models have difficulty in dealing with zero-shot scenarios where graph embedding models have to infer graph structures directly from texts. To solve these problems, we propose a novel framework, namely Text-driven Graph Embedding with Pairs Sampling (TGE-PS). TGE-PS uses Pairs Sampling (PS) to improve the sampling strategy of RW, being able to reduce ~99% training samples while preserving competitive performance. TGE-PS uses Text-driven Graph Embedding (TGE), an inductive graph embedding approach, to generate node embeddings from texts. Since each node contains rich texts, TGE is able to generate high-quality embeddings and provide reasonable predictions on existence of links to unseen nodes. We evaluate TGE-PS on several real-world datasets, and experiment results demonstrate that TGE-PS produces state-of-the-art results on both traditional and zero-shot link prediction tasks.

All Hamiltonian complexity results to date have been proven by constructing a local Hamiltonian whose ground state -- or at least some low-energy state -- is a "computational history state", encoding a quantum computation as a superposition over the history of the computation. We prove that all history-state Hamiltonians must be critical. More precisely, for any circuit-to-Hamiltonian mapping that maps quantum circuits to local Hamiltonians with low-energy history states, there is an increasing sequence of circuits that maps to a growing sequence of Hamiltonians with spectral gap closing at least as fast as O(1/n) with the number of qudits n in the circuit. This result holds for very general notions of history state, and also extends to quasi-local Hamiltonians with exponentially-decaying interactions. This suggests that QMA-hardness for gapped Hamiltonians (and also BQP-completeness of adiabatic quantum computation with constant gap) either require techniques beyond history state constructions. Or gapped Hamiltonians cannot be QMA-hard (respectively, BQP-complete).

This paper explains dedications in the dative and with the hyper formula as bearing two distinct religious meanings and social implications, while also observing that they could be used in interaction in order to express specific conceptual and social messages. The dative ritually positions the honoured rulers at the same level as traditional gods, whereas the hyper formula expresses ritual intercession by the gods for a third party. Ritual agents using hyper intended to share the merit of performing a ritual – and the consequent divine benevolence – with a third, often absent party. Besides its religious significance, performing a religious act in the name of, and for the benefit of a person also has economic and social implications. Thus ritual agents making use of the hyper formula could stress their social standing as well as express their personal bonds with the benefiting party. The broad perspective of the study (global and Ptolemaic perspectives; institutional and individual initiative; inscriptions and papyri) enables an encompassing understanding of the implications of dedicatory habits on the definition of the religious figure of the sovereigns, the ritual expression of social hierarchy and the intercultural encounters between Greeks and non-Greeks.

My position is that the opening sentence and the first five chapters must be regarded as the prologue which has been written with „preconceived formal concepts”. Herodotus took these concepts from rhetoric. The prologue consists of two parts. The first part is the opening sentence which gives the title and alludes to the subject and the general aim of the work. The second part of the prologue deals with the Persian, Phoenician, and Herodotean discussion of mythical origins of the conflict between Asia and Europe. In the original version, Zeus as womanizer impregnates Io, and the jealous Hera turns her into a white cow, fleeing a gadfly, who finally arrives in Egypt. Herodotus rationalizes this original myth of Io, and in his rationalized story, the sea and the ships play an important part. So the first wrong was done by the Phoenicians who abducted Io by ship, and sailed away for Egypt. Next certain Greeks landed at Tyre in Phoenice and carried off the king’s daughter Europe. According to the original Cretan myth „Europe arrived at Crete riding the back of a bull-shaped Zeus”. Herodotus rationalized this myth, too, and it is clear from the situation, that the abduction of Europe happened on a ship at sea.

Fechner's law and its modern generalizations can be regarded as manifestations of alternative forms of arithmetic, coexisting at stimulus and sensation levels. The world of sensations may be thus described by a generalization of the standard mathematical calculus.

In this paper, we would like to propose our web-based application for Islamic history learning system, named Digitory-Digital History. There are two main navigations to browse historical stories on the web. One is location-based navigation using on-line map which gives users access to understand events during Islamic introduction to Indonesia based on the location. Alternatively, users can browse on time base using sliding navigation marked timely, so they can comprehend history in time sequence. Implementing semantic web, this web-app can suggest users related articles, either based on time series, location similarities, or time-domain similarities, and also suggest pictures related to the articles. AJAX strengthen the real-time access and interactivity as users navigate around the web. By the end of this research, we will have the web-app prototype completed with its fundamental location-based navigation, semantic relationship among articles and pictures, and time- based navigation system. As the web-app deployed, we have some volunteers to try our application so that we can evaluate its result, particularly its effectiveness.

Recent studies of radioisotopes in tree rings or ice cores suggest that extreme space weather events occurred in the pre-telescope age. Observational records of naked-eye sunspots and low-latitude auroras in historical documents in pre-telescopic age can provide useful information on past solar activity. In this paper, we present the results of a comprehensive survey of records of sunspots and auroras in Chinese official histories from the 6th century to the 10th century, in the period of Suí, Táng, the Five Dynasties and Ten Kingdoms. These official histories contain records of continuous observations with well-formatted reports conducted under the policy of the government. A brief comparison of the frequency of observations of sunspots and auroras with the observations of radioisotopes as an indicator of solar activity during the corresponding periods is provided. Based on our data, we survey and compile the records of sunspots and auroras in historical documents from variouslocations and in several languages, and ultimately provide these as open data to the scientific community.

We propose and demonstrate experimentally a scheme to create entangled history states of the Greenberger-Horne-Zeilinger (GHZ) type. In our experiment, the polarization states of a single photon at three different times are prepared as a GHZ entangled history state. We define a GHZ functional which attains a maximum value $1$ on the ideal GHZ entangled history state and is bounded above by $1/16$ for any three-time history state lacking tripartite entanglement. We have measured the GHZ functional on a state we have prepared experimentally, yielding a value of $0.656\pm 0.005$, clearly demonstrating the contribution of entangled histories.
