Revising Beliefs in Light of Unforeseen Events [Dataset]
No full textBayesian updating is the dominant theory of learning. However, the theory is silent about how individuals react to events that were previously unforeseen. We study how decision makers update their beliefs if unforeseen events materialize, and under which conditions they revise their views about previously observed relationships. We base our analysis on the framework of “reverse Bayesianism”, under which the relative likelihoods of prior beliefs remain unchanged after an unforeseen event materializes. We find that participants do not systematically deviate from reverse Bayesianism when the unforeseen changes result in a new world that contains elements of the old world. In contrast, if a regime change is possible, decision makers eventually overhaul their model of the old world in favor of a completely different view of uncertainty
WSI-Babel-Shark: Empty Whole-Slide Images for Slide-Label Metadata Extraction
No full textThis dataset contains 22 whole-slide image (WSI) files in SVS format, digitized using a Leica GT450 scanner. All WSIs were intentionally scanned without tissue; only the physical slide labels are present. The purpose of this dataset is to support the evaluation and benchmarking of the WSI-Babel-Shark metadata-extraction pipeline.
Empty slides allow reduced file sizes, preservation of SVS metadata, and controlled conditions for benchmarking label-processing components, including OCR, DataMatrix decoding, stain parsing, SlideID reconstruction, and metadata harmonization. All WSIs retain full TIFF tiling, SVS headers, and Leica metadata. Files were manually inspected to ensure complete de-identification, and all CaseIDs and SlideIDs represent synthetic test cases.
A ground-truth CSV file containing validated metadata fields is included for benchmarking.
No patient-identifying information is contained in any file

Functional and structural organization of medial entorhinal cortex layer VI [data]
No full textDeep layers (V/VI) of the entorhinal cortex transfer hippocampal neuronal activity to downstream neocortical networks. In addition, neurons in layer VI (LVI) of the medial entorhinal cortex (MEC) project back to all hippocampal subregions and contribute to spatial coding and memory. Their role in the processing of hippocampal output signals and their interaction with LV neurons is, however, unknown. We show that spontaneously occurring hippocampal sharp wave-ripple complexes reliably propagate from area CA1 to MEC LVI. Using anterograde tracing and in vitro optogenetics, we confirm direct hippocampal projections to LVI and show that these follow a parallel dorsoventral topography. Further investigation of the MEC deep layer network revealed very sparse excitatory connections between LVI and LVb or LVI and LVa neurons in both directions. Together, our results establish organizational principles for the hippocampal-MEC LVI output circuit and suggest largely parallel signal processing through different cellular subpopulations in MEC deep layers
Can motivational interviewing in emergency care reduce alcohol consumption in young people? A systematic review and meta-analysis [research data and code]
No full textAims: We investigate the effect of motivational interviewing (MI), delivered in a brief intervention during an emergency care contact, on the alcohol consumption of young people who screen positively for present or previous risky alcohol consumption.
Methods: MEDLINE, CINAHL, EMBASE, PsycARTICLES, PsycINFO, PSYNDEX and Scopus were searched for randomized controlled trials with adolescents or young adults that compared MI in an emergency care setting to control conditions and measured drinking outcomes.
Results: Six trials with 1433 participants, aged 13–25 years, were included in the systematic review and meta-analysis. MI was never less efficacious than a control intervention. Two trials found significantly more reduction in one or more measures of alcohol consumption in the MI intervention group. One trial indicated that MI may be used most effectively in young people with high-volume alcohol consumption. Separate random effects meta-analyses were performed based on the highest impact that MI added on reducing the drinking frequency and the drinking quantity at any point in time during the different study periods. Their results were expressed as standardized mean differences (SMDs). The frequency of drinking alcohol decreased significantly more after MI than after control interventions (SMD ≤ −0.17, P ≤ 0.03). In addition, MI reduced the drinking quantity further than control interventions in a meta-analysis of the subset of trials that were implemented in the USA (SMD = −0.12, P = 0.04). Meta-analyses of the smallest mean differences between MI and control groups detected no differences in alcohol use (SMD ≤ 0.02, P ≥ 0.38).
Conclusion: MI appears at least as effective and may possibly be more effective than other brief interventions in emergency care to reduce alcohol consumption in young people
Heidelberg Mouth Retractor [data]
No full textThe 'Heidelberg Mouth Retractor‘ is a customizable, disposable mouth retractor designed for temporomandibular joint (TMJ) imaging. The retractor can be produced using a conventional vat polymerization printer with any resin approved for intraoral use. The device allows for reproducible and chairside defined mouth opening, which for many patients is critical to obtaining conclusive TMJ imaging. The technique is intended to reduce motion artifacts and supports a range of mouth openings from 12 to 72 mm, depending on the patient's requirements. The single-use design of the retractor facilitates its application in clinical settings and can be modified for patients with malocclusions. The approach is considered resource-efficient and demonstrates the feasibility of using 3D printing for customized oral appliances in dentistry

[Ergänzungsmaterial zu: Die mittelalterliche Verwendung Osteifeler Tuffe im Kartenbild]
No full textList of medieval buildings in Belgium, Denmark, Germany and the Netherlands in which volcanic tuff of the Eastern Eifel Area of Germany was used. The list contains 1108 buildings, mainly churches but also secular building like fortifications and residential buildings.Until now there had been some regional studies about churches built with this material, but no compehensive list or map covering the whole distribution area. The presented list and the map based on the list is an attempt to present the first comprehensive transnational representation of the medieval use of tuff from the Eastern Eifel. The list provides the positions of the buildings representetd in WGS 84 (EPSG 4326), monument-IDs, where applicable, and some other basic information
The Art Collection of the French Royal Academy of Painting and Sculpture [data and software]
No full text
Over the century and a half of its existence (1648–1793), the Académie royale de peinture et de sculpture amassed a collection of more than 15,000 artworks (paintings, sculptures, prints, drawings, casts, and medals). The core of this collection consisted of reception pieces (morceaux de réception) – works that young artists presented to an academic jury to become members of the institution. Additionally, the collection featured Prix-de-Rome-winning paintings and bas-reliefs, commissioned portraits of the Académie’s patrons, académie drawings by student and professors, plaster casts of classical sculptures, miscellaneous donated works of art, furniture, and unclassifiable objects (e.g., skeletons used in teaching human anatomy).
As almost all the prominent artists of the old regime were members of the Académie royale, the Académie’s art collection brought together such iconic reception pieces as Watteau’s Pilgrimage to the Isle of Cythera (1717), Chardin’s Ray (1728) and Greuze’s Septimius Severus and Caracalla (1769). These and other examination works now offer valuable insights into the aesthetic values of the institution. Académies, plaster casts, and other objects used in teaching shed light on the educational process. While commissioned portraits of the Académie’s patrons and donated works of art illuminate the personal networks behind it. Collectively, these objects reveal how the most influential art institution in eighteenth-century Europe viewed and positioned itself.
Together with the Académie, the collection changed its home numerous times, moving from the Saint-Eustache to the Hôtel Clisson, rue Sainte-Catherine, and the Palais-Royal, but for most of its history, from 1692 to 1793, was housed in the Louvre. The collection’s arrangement in the Louvre was a remarkable example of eighteenth-century curatorial work and an “internal” counterpart to the Académie’s public display, the Salon. Unlike the Salon Carré, the main rooms of the Académie were accessible only to exclusive visitors, yet the works they contained served as major reference points for students and members, many of whom not only worked but also lived in the Palace.
After the French Revolution, the art collection of the Académie was dispersed and today is shared by the Louvre, the Versailles, the ENSBA, and many other museums in France and worldwide.
In collaboration with the Centre Dominique-Vivant Denon (Louvre), the INHA, and the Beaux-Arts de Paris, we have initiated a project to reconstruct the Académie’s art collection using digital methods. The first phase involved building a database establishing what objects originally comprised the collection and where they are preserved now. To demonstrate the importance of the collection to understanding ancien régime art, we have also launched a book series, which will open with a volume on reception pieces (scheduled for publication in 2024). Our next step will be the creation of a 3D model digitally recreating the arrangement of the collection in the eighteenth-century Louvre.

Investigating the design of macromolecular-based inks for two-photon 3D laser printing [data]
No full textTwo-photon 3D laser printing (2PLP) is one of the most versatile methods for additive manufacturing of micro- to nano-scale objects with arbitrary geometries and fine features. With advancing technological capability and accessibility, the demand for new and versatile inks is increasing, with a trend toward printing functional or responsive structures. One approach for ink design is the use of a macromolecular ink consisting of a ‘pre-polymer’ functionalized with photocrosslinkable groups to enable printability. However, so far the synthesis of pre-polymer inks for 2PLP often relies on an arbitrary choice rather than systematic design. Additionally, current structure–property relationship studies are limited to commercial or small molecule–based inks. Herein, three macromolecular inks with varied compositions, molecular weights, and glass transition temperatures are synthesized and formulated into inks for 2PLP. 3D microstructures are fabricated and characterized in-depth with scanning electron microscopy as well as infrared spectroscopy and nanoindentation to enable the determination of structure–processability–property relationships. Overall, it is clearly demonstrated that the macromolecular design plays a role in the printability and mechanical properties of the obtained materials
