Longitudinal Risk Prediction in Mammography with Privileged History Distillation

Banafsheh Karimian, Alexis Guichemerre, Soufiane Belharbi et al.

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.

Interconnection between house and fenced area

Petra Schindlerová, Jana Klementová, Miroslav Popelka et al.

The article aims to examine the relationship between the use of longhouses and adjacent fenced areas at the Linear Pottery culture (LBK) settlement in Hostivice-Sadová. The analysis focuses on house no. 1 and 15 and the rectangular fenced areas defined mainly by single posts that were excavated next to their eastern walls. The study includes representative pottery assemblages from settlement features and construction pits dated to the two subsequent phases in the middle stage of LBK. Formation processes and the proportion of decoration style were analysed in combination with radiocarbon dating. The article also addresses whether fenced areas were later used as refuse disposal spaces. The results show that the fills of the features in the fenced areas were deposited later than the house unit assemblages were formed. In both cases, there is no significant evidence of using fenced areas later for waste disposal. Additionally, the social and economic aspects of these houses are discussed as the construction, length, fenced areas, and concentration of finds indicate their important social and economic role within the settlement.

Waterfront Redevelopment Five Decades Later: An Updated Typology and Research Agenda

Enrico Tommarchi

Since the second half of the twentieth century, when maritime practices began migrating outside their traditional central city areas, urban regeneration at the water’s edge has been one of the key issues in port cities’ planning agendas. Waterfronts in port cities have become strategic areas for a range of reasons, such as economic growth, city branding, and addressing housing pressures. However, recent studies also show how their transformation is now more profoundly influenced by hypermobile capital and global finance, and by broad sustainability concerns. The established narrative of waterfront redevelopment as a response to weakening port‐city relationships no longer necessarily represents the present of all port cities, as more nuanced accounts are needed. With examples from Europe and across the world, this article reflects on waterfront redevelopment practices, by building on existing attempts to provide typologies and periodise the history of this phenomenon and focussing on the key approaches emerging in the last decades. It is argued that today’s approaches to waterfront redevelopment, and ultimately contemporary relationships between ports and cities, are changing and possibly differentiating from the “port out, city in” rationale underpinning past schemes. Current practices appear to be ranging from the wholesale transformation of redundant waterfronts into neoliberal urban spaces for consumption and capital accumulation to more “fine‐grained” planning strategies to build more (environmentally, but also economically, socially, and culturally) sustainable urban waterfronts by integrating or restoring port‐related activities within mixed‐used areas.

HAFixAgent: History-Aware Program Repair Agent

Yu Shi, Hao Li, Bram Adams et al.

Automated program repair (APR) has recently shifted toward large language models and agent-based systems, yet most systems rely on local snapshot context, overlooking repository history. Prior work shows that repository history helps repair single-line bugs, since the last commit touching the buggy line is often the bug-introducing one. In this paper, we investigate whether repository history can also improve agentic APR systems at scale, especially for complex multi-hunk bugs. We present HAFixAgent, a History-Aware Bug-Fixing Agent that injects blame-derived repository heuristics into its repair loop. A preliminary study on 854 Defects4J (Java) and 501 BugsInPy (Python) bugs motivates our design, showing that bug-relevant history is widely available across both benchmarks. Using the same LLM (DeepSeek-V3.2-Exp) for all experiments, including replicated baselines, we show: (1) Effectiveness: HAFixAgent outperforms RepairAgent (+56.6\%) and BIRCH-feedback (+47.1\%) on Defects4J. Historical context further improves repair by +4.4\% on Defects4J and +38.6\% on BugsInPy, especially on single-file multi-hunk (SFMH) bugs. (2) Robustness: under noisy fault localization (+1/+3/+5 line shifts), history provides increasing resilience, maintaining 40 to 56\% success on SFMH bugs where the non-history baseline collapses to 0\%. (3) Efficiency: history does not significantly increase agent steps or token costs on either benchmark.

The role of Projects of Common Interest in reaching Europe's energy policy targets

Bobby Xiong, Iegor Riepin, Tom Brown

The European Union aims to achieve climate-neutrality by 2050, with interim 2030 targets including 55% greenhouse gas emissions reduction compared to 1990 levels, 10 Mt p.a. of a domestic green H2 production, and 50 Mt p.a. of domestic CO2 injection capacity. To support these targets, Projects of Common and Mutual Interest (PCI-PMI) - large infrastructure projects for electricity, hydrogen and CO2 transport, and storage - have been identified by the European Commission. This study focuses on PCI-PMI projects related to hydrogen and carbon value chains, assessing their long-term system value and the impact of pipeline delays and shifting policy targets using the sector-coupled energy system model PyPSA-Eur. Our study shows that PCI-PMI projects enable a more cost-effective transition to a net-zero energy system compared to scenarios without any pipeline expansion. Hydrogen pipelines help distribute affordable green hydrogen from renewable-rich regions in the north and southwest to high-demand areas in central Europe, while CO2 pipelines link major industrial emitters with offshore storage sites. Although these projects are not essential in 2030, they begin to significantly reduce annual system costs by more than EUR 26 billion from 2040 onward. Delaying implementation beyond 2040 could increase system costs by up to EUR 24.2 billion per year, depending on the extent of additional infrastructure development. Moreover, our results show that PCI-PMI projects reduce the need for excess wind and solar capacity and lower reliance on individual CO2 removal technologies, such as Direct Air Capture, by 13 to 136 Mt annually, depending on the build-out scenario.

Gaia-Sausage-Enceladus star formation history as revealed by detailed elemental abundances

H. Ernandes, D. Feuillet, S. Feltzing et al.

The Gaia-Sausage-Enceladus was the last major merger and central turning point in the Milky Way's story. This event, comparable in mass to the Large Magellanic Cloud today, left behind significant debris that provides valuable insights into the assembly history of our Galaxy and the chemical evolution of dwarf galaxies. By examining the aftermath of the GSE merger, we can delve deeper into understanding how the Milky Way's formation unfolded and how dwarf galaxies evolved chemically. Specifically, the distinct patterns of neutron capture elements such as Eu and Ba, along with Mg, offer clues about the star formation history. Through a comprehensive analysis of data compiled in the SAGA database, we investigated the Gaia Sausage-Enceladus' star formation history. Elemental abundance ratios ([Eu/Mg], [Ba/Mg], and [Eu/Ba]) derived from this study, when compared with those of surviving Milky Way satellites, indicate that the GSE experienced a prolonged period of slow star formation, lasting over 2 Gyr, until it was eventually quenched by merging with the Milky Way. Consequently, these elemental signatures serve as a unique window into the complex history of both surviving and accreted satellites orbiting our Galaxy.

Raw materials for Neolithic ground tools from the extraction fields at Bílý Kámen Hill, Central Bohemia

Pavel Burgert, Antonín Přichystal, Petr Gadas

The assemblage of ground tools and their fragments from the site of Bílý Kámen Hill near the town of Sázava (Czech Republic, Central Bohemia) is one of the largest chronologically uniform collections in Central Europe. Based on the dominant representation of bored axe-hammers, we date it to the late phase of the Stroked Pottery culture (SBK; 5100/5000–4500/4400 cal BC). Their connection to the extraction of local marble and the production of prestigious bracelets raises many questions. The material composition of the assemblage could be the key to understanding the origin of the artefacts. In this article, we examined 912 samples using optical and electron microscopy methods. This points to the dominant representation of amphibole-rich Jizera Mountains-type metabasites. Other rocks are represented only in small quantities and raw materials of local origin are probably missing in the assemblage. It is thus comparable to assemblages from contemporaneous settlement sites, although we do not yet know of stable occupation in the vicinity of the site, nor do we even anticipate its existence.

Star-forming and Quiescent Central Galaxies Cluster Similarly: Implications for the Galaxy-Halo Connection

James Kakos, Aldo Rodriguez-Puebla, Joel R. Primack et al.

We measure the clustering of low-redshift SDSS galaxies as a function of stellar mass ($10.0<\log(M_*/M_\odot)<11.5$) and specific star formation rate (sSFR) and compare the results to models of the galaxy--halo connection. We find that the auto-correlation functions of central galaxies exhibit little dependence on sSFR, with the well-known stronger clustering of quiescent galaxies mainly attributable to satellites. Because halo assembly history is known to affect distinct halo clustering, this result implies that there is little net correlation between halo assembly history and central galaxy sSFR. However, cross-correlations with satellites are stronger for quiescent centrals than star-forming centrals, consistent with quiescent centrals having more satellites in their haloes at fixed $M_*$, as found in SDSS group catalogues. We model the galaxy--halo connection in an $N$-body simulation by assigning sSFRs to central galaxies in three different ways. Two of the models depend on halo assembly history (being based on halo accretion rate or concentration), while the third is independent of halo assembly history (being based on peak halo circular velocity, $V_\text{peak}$, a proxy for halo mass). All three models replicate the observed auto-correlations of central galaxies, while only the $V_\text{peak}$ model reproduces the observed cross-correlations with satellites. This further suggests that the effects of halo assembly history may not be easily seen in auto-correlations of centrals and implies that a more complete understanding of central galaxy clustering may require more than auto-correlations of centrals alone. Additionally, the good agreement with the $V_\text{peak}$ model supports the idea that quiescent galaxies reside in more massive haloes than star-forming galaxies at fixed $M_*$.

Orbán Ferenc építész-tanár bírósági épületei Debrecenben és környékén

Zoltán Megyeri-Pálffi

A bírói hatalomról szóló 1869. évi IV., majd az 1871. évi, az elsőfolyamodású bíróságokat létrehozó szervezeti törvények nyomán létrejött a modern bírósági szervezetrendszer Magyarországon. A bíróságok működéséhez a személyi feltételeken túl a dologi háttérnek is rendelkezésre kellett állni. Ez utóbbi elsősorban a bíróságok elhelyezését jelentette, azaz azokat az épületeket, amelyekben megkezdhették munkájukat. Ennek a bírósági épületállománynak a megteremtése hosszú évtizedekbe tellett. A törvényszékek építési periódusát követően (kb. 1880– 1910) az állam a járásbíróságok méltó elhelyezésére koncentrált. Az 1910-es évektől látni azt, hogy új járásbírósági épületeket emeltek az országban. Ez folyamat a két világháború közötti időszakban is folytatódott. E feladatkörben is szakértő építészekkel találkozhatunk. Egyike volt ezeknek – a nagyközönség által talán kevésbé ismert – Orbán Ferenc építész-tanár, aki számos járásbírósági épület tervezését jegyezte az 1920-as években. Szűkebb régiónkban: Debrecenben, Berettyóújfaluban, Hajdúböszörményben és Hajdúszoboszlón találkozhatunk épületével. E rövid interdiszciplináris jellegű tanulmány ezekre, illetve az építész munkásságára tér ki.

Hajdú-Bihar megye társadalmi helyzetének bemutatása a számok tükrében

Viktória Vida, István Szűcs

Az általunk készített tanulmány célja, hogy áttekintést nyújtson Hajdú-Bihar megye társadalmi helyzetének alakulásáról. Hajdú-Bihar megye, az Észak-alföldi régió gazdasági, oktatási, tudományos és kulturális szerepkörrel bíró központja. Adottságai kedvezőek a szerepkör betöltéséhez, gazdasági, oktatási, kereskedelmi, kulturális, egészségügyi kapcsolatai az országhatáron túl is jelentősek. Hajdú-Bihar megyével kapcsolatban fontosnak tartjuk még megemlíteni a logisztikai szerepének kiaknázását, valamint regionális tudásbázis szerepkörét bemutatni. Hajdú-Bihar megye központja Debrecen város, a népességszámát tekintve Magyarország második, az Alföld legnagyobb városa. Debrecen már évtizedek óta Hajdú-Bihar megye kiemelkedő települése, a város társadalmi-gazdasági hatása az egész régióra kiterjed, hiszen a város regionális központként is funkcionál. A fentebb említett hatások közül jelen tanulmányban Hajdú-Bihar megye társadalmi hatásaira fókuszálunk, és ennek elemzéséhez, alátámasztásához a helyi és az országos statisztikai adatokat alapul véve készítettünk számításokat. A társadalmi hatásokat elsősorban demográfiai szempontból vizsgáltuk meg (népesség száma, nem, kor és iskolai végzettség szerinti összetétele, képzettsége, foglalkoztatottsága, jövedelmi viszonyok) a korábbi évekkel és országos adatokkal összehasonlítva.

In Search of Postmodern City: Urban Changes and Continuities in East Central Europe between Late Socialism and Capitalism (1970–2000)

Matěj Spurný, Petr Roubal, Henrieat Moravčíková et al.

How is it possible to relate the dramatic story of the metropolises of Central and Eastern Europe at the end of the 20th century? Perhaps the path of these cities from late socialism into restored capitalism could be framed as a tale of emancipation from the dead hand of rigid central planning, highlighting the potential of a deregulated market and the polyphony of democratic participation. Or conversely, as the search for an escape from the failure of modernist utopias, bringing in its wake the daring architectural experiments and the chaotic urbanistic reality of postmodernism. Yet no less justifiably, we could also speak of the self-destruction of urban-planning expertise, a narrative of the gradually weakening position of architects and even more so planners as they relinquished the field to spontaneous development, lay actors, political compromises, and primarily neoliberal commodification as the chief factor shaping the growth of cities in the wild 1990s. An unleashing of creative potential – or a new hegemony grounded in “creative destruction” and deregulation of public planning? The primary ambition of the present issue is to understand the conditions behind the transformation of architecture, urban design, and indeed city functioning in the Central and Eastern Europe region that occurred in the final decade of the 20th century. Its theme is derived from an ongoing research project involving researchers from both the Institute for Contemporary History of the Czech Academy of Sciences (ÚSD AV ČR) in Prague and the Department of Architecture at the Historical Institute of the Slovak Academy of Sciences (HÚ SAV) in Bratislava, examining the transition from late socialism to postsocialism through the example of the development of the two capital cities of the former federal state of Czechoslovakia. Yet the current issue also works to present a wider geographic picture of the region in the condition of post-socialism. The reality of the 1990s was not formed exclusively by the export of economic, intellectual, or aesthetic situations from the “West” to the “East” after the collapse of the Iron Curtain: without a thorough understanding of the essence of late socialism, we cannot understand what happened to the cities between the Baltic and the Black Sea in the Nineties – or more importantly, why it did.

Uniform probability in cosmology

Sylvia Wenmackers

Problems with uniform probabilities on an infinite support show up in contemporary cosmology. This paper focuses on the context of inflation theory, where it complicates the assignment of a probability measure over pocket universes. The measure problem in cosmology, whereby it seems impossible to pick out a uniquely well-motivated measure, is associated with a paradox that occurs in standard probability theory and crucially involves uniformity on an infinite sample space. This problem has been discussed by physicists, albeit without reference to earlier work on this topic. The aim of this article is both to introduce philosophers of probability to these recent discussions in cosmology and to familiarize physicists and philosophers working on cosmology with relevant foundational work by Kolmogorov, de Finetti, Jaynes, and other probabilists. As such, the main goal is not to solve the measure problem, but to clarify the exact origin of some of the current obstacles. The analysis of the assumptions going into the paradox indicates that there exist multiple ways of dealing consistently with uniform probabilities on infinite sample spaces. Taking a pluralist stance towards the mathematical methods used in cosmology shows there is some room for progress with assigning probabilities in cosmological theories.

Functional Central limit theorems for epidemic models with varying infectivity and waning immunity

Arsene-Brice Zotsa-Ngoufack

We study an individual-based stochastic epidemic model in which infected individuals become susceptible again following each infection (generalized SIS model). Specifically, after each infection, the infectivity is a random function of the time elapsed since the infection, and each recovered individual loses immunity gradually (equivalently, becomes gradually susceptible) after some time according to a random susceptibility function. The epidemic dynamics is described by the average infectivity and susceptibility processes in the population together with the numbers of infected and susceptible/uninfected individuals. In \cite{forien-Zotsa2022stochastic}, a functional law of large numbers (FLLN) is proved as the population size goes to infinity, and asymptotic endemic behaviors are also studied. In this paper, we prove a functional central limit theorem (FCLT) for the stochastic fluctuations of the epidemic dynamics around the FLLN limit. The FCLT limit for the aggregate infectivity and susceptibility processes is given by a system of stochastic non-linear integral equation driven by a two-dimensional Gaussian process.

A Comparative History of Local Resilience?

Gábor Egry

The classic accounts of the history of the Habsburg Empire emphasized the importance of the conflict of nationalities and alleged that national oppression was the root cause of the Empire’s dissolution in 1918. Based on new results, however, the Nepostrans ERC project has raised two important issues: caution against the idea of all-pervasive nationalisms, and the perspective that the disappearance of Austria–Hungary was not a clear and sharp break and that continuities were just as important as ruptures. Built on concepts like ‘phantom boundaries’ (Phantomgrenzen) and New Imperial History, the focus of the Nepostrans ERC project is a dual one. The first aspect centers on the transformation of imperial society, governance, and institutions that emerged due to the war effort, and the second on the transition out of the imperial framework as the key consequence of the latter, with special attention given to social and institutional consequences and the enabling of new statebuilding efforts at a local level. The fundamental issues addressed by the project—running from 2018 to 2023—are the various relations between statehood and society at the local and regional levels that are examined in nine cases: Tyrol,  Hradec Králové (Königrätz), southern Banat, Znojmo (Znaim), Prekmurje (Muravidék), Rijeka (Fiume), Kolomiya (Kolomea), Baia Mare (Nagybánya), and the outskirts of Budapest. The cases were primarily selected to represent typical variations in  the social and political configuration during investigated period, 1917–1930.

Face‐Work: Making Hair Matter in Sixteenth‐Century Central Europe

Stefan Hanß

ABSTRACTBringing gender history, the history of the body and art history into a conversation with material culture studies, this article argues that the sudden fashionability of beards in Renaissance Europe has been intricately linked with a culture of material and visual experimentation. I propose shifting perspectives from a focus on the symbolism of beards towards examining how early modern ways of material engagement with the matter of hair crafted a visual attention to facial hair that made up the sociocultural significance of beards. Focusing on how people made hair matter, I suggest working with the concept of face‐work. In particular, this article maps how the Reformation upheavals and the rise of new visual practices dynamised Renaissance protagonists’ creative engagement with facial hair as a means for staging the self.
