Abstract

OBJECTIVES/GOALS: We aimed to find the histology-specific markers that were predictive of post-operative long-term chordoma recurrence (≤1 year) using trained multiple tree-based machine learning (ML) algorithms. METHODS/STUDY POPULATION: We reviewed the records of patients who had treatment for clival and spinal chordomas between January 2017 and June 2021 across the Mayo Clinic enterprise (Minnesota, Florida, and Arizona). Patients were excluded if they had no histopathology or recurrence as an outcome. Demographics, type of treatment, clinical and radiological follow-up duration, histopathology, and other relevant clinical factors were abstracted from each patient record. Decision tree and random forest classifiers were trained and tested to predict the long-term recurrence based on unseen data using an 80/20 split. The performance of the model was optimized using tenfold cross-validation. RESULTS/ANTICIPATED RESULTS: One hundred fifty-one patients were identified: 58 chordomas from the clivus, 48 chordomas of the mobile spine, and 45 sacrococcygeal. Subtotal Resection followed by radiation therapy, was the most common treatment modality, followed by Gross Total resection, then radiation therapy. The multivariate analysis defines the molecular predictors of recurrence following resection. S100 and pan-cytokeratin is more likely to increase the risk of post-operative recurrence (OR= 3.67; CI= [1.09,12.42], p=0.03). In the decision tree analysis, a clinical follow-up > 1897 days was found in 37 % of encounters and a 90% chance of being classified for recurrence (Accuracy= 77%). Factors predicting long-term recurrence are the patient’s age, type of surgical treatment, location of the tumor, S100, pan-cytokeratin, and EMA. DISCUSSION/SIGNIFICANCE: Our molecular and clinicopathological variables combined with tree-based ML tools successfully demonstrate a high capacity to individually identify the patient’s recurrence pattern with an accuracy of 77%. S100, pan-cytokeratin, and EMA were the histologic drivers of recurrence.

Abstract

PURPOSE: Neurofibromatosis type 2 (NF2) and schwannomatosis (SWN) are genetically distinct tumor predisposition syndromes with overlapping phenotypes. We sought to update the diagnostic criteria for NF2 and SWN by incorporating recent advances in genetics, ophthalmology, neuropathology, and neuroimaging. METHODS: We used a multistep process, beginning with a Delphi method involving global disease experts and subsequently involving non-neurofibromatosis clinical experts, patients, and foundations/patient advocacy groups. RESULTS: We reached consensus on the minimal clinical and genetic criteria for diagnosing NF2 and SWN. These criteria incorporate mosaic forms of these conditions. In addition, we recommend updated nomenclature for these disorders to emphasize their phenotypic overlap and to minimize misdiagnosis with neurofibromatosis type 1. CONCLUSION: The updated criteria for NF2 and SWN incorporate clinical features and genetic testing, with a focus on using molecular data to differentiate the 2 conditions. It is likely that continued refinement of these new criteria will be necessary as investigators study the diagnostic properties of the revised criteria and identify new genes associated with SWN. In the revised nomenclature, the term "neurofibromatosis 2" has been retired to improve diagnostic specificity. ispartof: GENETICS IN MEDICINE vol:24 issue:9 pages:1967-1977 ispartof: location:United States status: published

Abstract

Although polling is not irredeemably broken, changes in technology and society create challenges that, if not addressed well, can threaten the quality of election polls and other important surveys on topics such as the economy. This essay describes some of these challenges and recommends remediations to protect the integrity of all kinds of survey research, including election polls. These 12 recommendations specify ways that survey researchers, and those who use polls and other public-oriented surveys, can increase the accuracy and trustworthiness of their data and analyses. Many of these recommendations align practice with the scientific norms of transparency, clarity, and self-correction. The transparency recommendations focus on improving disclosure of factors that affect the nature and quality of survey data. The clarity recommendations call for more precise use of terms such as “representative sample” and clear description of survey attributes that can affect accuracy. The recommendation about correcting the record urges the creation of a publicly available, professionally curated archive of identified technical problems and their remedies. The paper also calls for development of better benchmarks and for additional research on the effects of panel conditioning. Finally, the authors suggest ways to help people who want to use or learn from survey research understand the strengths and limitations of surveys and distinguish legitimate and problematic uses of these methods.

Abstract

Verglichen mit den Risiken und Konflikten des fossil-nuklearen Zeitalters erscheinen die erneuerbaren Energien in einem überwiegend positiven Licht. Allerdings schafft die Transformation zu einer kohlenstoffarmen Energieversorgung neue Energielandschaften, die einen hohen Bedarf an Landflächen mit sich bringen – was ebenfalls Energiekonflikte provozieren kann. Um derartige Konflikte zu mindern und die Akzeptanz der Bevölkerung zu gewinnen, kann Technikfolgenabschätzung einen Beitrag leisten, wenn sie sich auf räumliche agentenbasierte Modelle stützt. Diese Modelle repräsentieren die Entscheidungen von Stakeholdern über Energiealternativen, deren dynamische Interaktionen sowie daraus resultierende Landnutzungsoptionen und Energiepfade. Als Fallstudie dient Norddeutschland, wo Landwirte und Gemeinden als lokale Akteure der Energiewende agieren.

Abstract

This paper traces Heesoon Bai’s contributions to science education. Over the course of her career, Heesoon has written many scholarly articles that explore the foundational theories relevant to the culture of science education. Drawing from Eastern contemplative traditions, Heesoon aims to repair the separation between subject and object, a dualism that often operates in Western Science. She enjoins an animistic view of the world, where all things are alive and imbued with intrinsic value, and presents a view of education characterized by relational warmth and care. The essay is a compilation of testimonies from students who have worked with Heesoon Bai in the past. We present these accounts as a tribute to an outstanding educator who has made a positive contribution both in the field of science education and to the lives of many students.

Abstract

Meningeal solitary fibrous tumor (SFT) is a rare tumor with high propensity to recur and metastasize, even late in the course of disease. The WHO 2021 classification of CNS tumors divides SFT in 3 grades, based on mitotic index and necrosis. We re-examined our cohort of 126 patients (57 F, 69 M; mean age 53.0 years) with SFT, confirmed by STAT6 nuclear positivity and/or NAB2::STAT6 fusion, with extended follow-up (median 7.6 years; range 4 days-26.6 years). Tumors included 76 grade 1, 36 grade 2 and 14 grade 3 according to 2021 WHO criteria, evaluated at primary resection (n=90), recurrence (n=35), or metastasis (n=1). Fifty-six patients had one or more post-surgical events, the earliest event being local recurrence (n=41) or metastasis (n=15). Forty patients died (29 of disease; 9 of other causes; 2 unknown). Overall survival (OS), and progression-free survival (PFS, recurrence and/or metastasis) from time of primary resection (n=90) were not significantly associated with grade; however, risk of metastasis differed significantly (5-year estimates: 4.1%, 15.3%, and 37.8% for grades 1, 2, and 3 SFT, respectively; p=0.005). NAB2::STAT6 fusion status was known in 101 cases (51 = ex5-7-ex16-17, 26 = ex4_ex2-3; 12 = ex2-3_exANY/other and 12 =no fusion). Disease specific 5-year survival in primary tumors with molecular data (n = 75) was 80.0% in patients whose tumors harbored ex5-7_ex16-17 compared to 93.3% in all others combined (p=0.014). Targeted TERT promoter mutation testing was performed in 98 patients, revealing patients with tumors lacking TERT promoter mutation (n = 88) were younger at time of surgery than those harboring a mutation (n=10; p = 0.022), and none with a mutation harboring concurrent ex5-7_ex16-17 fusion (p = 0.0009). In summary, WHO 2021 grade is associated with risk of metastasis. Patients whose tumors harbor ex5-7_ex16-17 fusion have a higher risk of dying from the disease.

Abstract

The Simons Observatory is a ground-based cosmic microwave background experiment that consists of three 0.4 m small-aperture telescopes and one 6 m Large Aperture Telescope, located at an elevation of 5300 m on Cerro Toco in Chile. The Simons Observatory Large Aperture Telescope Receiver (LATR) is the cryogenic camera that will be coupled to the Large Aperture Telescope. The resulting instrument will produce arcminute-resolution millimeter-wave maps of half the sky with unprecedented precision. The LATR is the largest cryogenic millimeter-wave camera built to date, with a diameter of 2.4 m and a length of 2.6 m. The coldest stage of the camera is cooled to 100 mK, the operating temperature of the bolometric detectors with bands centered around 27, 39, 93, 145, 225, and 280 GHz. Ultimately, the LATR will accommodate 13 40 cm diameter optics tubes, each with three detector wafers and a total of 62,000 detectors. The LATR design must simultaneously maintain the optical alignment of the system, control stray light, provide cryogenic isolation, limit thermal gradients, and minimize the time to cool the system from room temperature to 100 mK. The interplay between these competing factors poses unique challenges. We discuss the trade studies involved with the design, the final optimization, the construction, and ultimate performance of the system.

Abstract

Modern science and engineering computing environments often feature storage systems of different types, from parallel file systems in high-performance computing centers to object stores operated by cloud providers. To enable easy, reliable, secure, and performant data exchange among these different systems, we propose Connector, a plug-able data access architecture for diverse, distributed storage. By abstracting low-level storage system details, this abstraction permits a managed data transfer service (Globus, in our case) to interact with a large and easily extended set of storage systems. Equally important, it supports third-party transfers: that is, direct data transfers from source to destination that are initiated by a third-party client but do not engage that third party in the data path. The abstraction also enables management of transfers for performance optimization, error handling, and end-to-end integrity. We present the Connector design, describe implementations for different storage services, evaluate tradeoffs inherent in managed vs. direct transfers, motivate recommended deployment options, and propose a model-based method that allows for easy characterization of performance in different contexts without exhaustive benchmarking.

Abstract

Purpose Researchers now have more ways than ever before to capture information about groups of interest. In many areas, these are augmenting traditional survey approaches – in others, new methods are potential replacements. This paper aims to explore three key trends: use of nonprobability samples, mobile data collection and administrative and “big data.” Design/methodology/approach Insights and lessons learned about these emerging trends are drawn from recent published articles and relevant scientific conference papers. Findings Each new trend has its own timeline in terms of methodological maturity. While mobile technologies for data capture are being rapidly adopted, particularly the use of internet-based surveys conducted on mobile devices, nonprobability sampling methods remain rare in most government research. Resource and quality pressures combined with the intensive research focus on new sampling methods, are, however, making nonprobability sampling a more attractive option. Finally, exploration of “big data” is becoming more common, although there are still many challenges to overcome – methodological, quality and access – before such data are used routinely. Originality/value This paper provides a timely review of recent developments in the field of data collection strategies, drawing on numerous current studies and practical applications in the field.

Abstract

Accounting and corporate reporting can be seen as a language for specific purposes. Such a language requires the use of terms and concepts with a precise and commonly shared meaning to allow effective and efficient communication. We analyze the term ‘non-financial information’, which has become a part of mandatory corporate reporting within the European Union (EU) through recent regulatory actions. Our analysis is based on a survey of the theoretical and empirical literature, on the rational of semantic theory, as well as on a questionnaire survey. The clear finding is that, up to now, neither a common meaning nor a generally accepted definition of ‘non-financial information’ exists. We derive from the applied theoretical concepts that this situation negatively impacts the efficiency and effectiveness of corporate communication. Against this background we discuss several venues that might help to overcome this deficiency like issuing a mandatory guideline or changing the terminology.

Abstract

Norian–Rhaetian reef carbonates are exposed in several localities in Taurus Mountains. They predominately contain hypercalcified sponges, followed by scleractinian corals and other less numerous organisms. A coherent Norian–Rhaetian reef structure is exposed near the small town of Saklıkent, west of Antalya. Foraminifers occur in reef carbonates of Saklıkent by numerous genera as shown in this paper. Two species —Siculocosta tauricaandSiculocosta sadati— are described as new. The foraminiferal association of Saklıkent is similar or almost identical to the associations known from the Norian–Rhaetian reefs of Sicily, Northern Calcareous Alps, and Greece but shows less similarity to the foraminiferal association from the Apennines, Italy. The most abundant foraminifers are milioliporoids, particularly galeanellids and cucurbitids. Some sessile and agglutinated foraminifers, includingAlpinophragmium perforatumFlügel, which mostly occurs abundantly in the Norian–Rhaetian reef carbonates, could not be found in the Saklıkent reef. This association of foraminifera is reported for the first time from a Norian–Rhaetian reef in the Taurus Mountains of Turkey.

Abstract

Background Short-term treatment for people with type 2 diabetes using a low dose of the selective endothelin A receptor antagonist atrasentan reduces albuminuria without causing significant sodium retention. We report the long-term effects of treatment with atrasentan on major renal outcomes.Methods We did this double-blind, randomised, placebo-controlled trial at 689 sites in 41 countries. We enrolled adults aged 18-85 years with type 2 diabetes, estimated glomerular filtration rate (eGFR) 25-75 mL/min per 1.73 m(2) of body surface area, and a urine albumin-to-creatinine ratio (UACR) of 300-5000 mg/g who had received maximum labelled or tolerated renin-angiotensin system inhibition for at least 4 weeks. Participants were given atrasentan 0.75 mg orally daily during an enrichment period before random group assignment. Those with a UACR decrease of at least 30% with no substantial fluid retention during the enrichment period (responders) were included in the double-blind treatment period. Responders were randomly assigned to receive either atrasentan 0.75 mg orally daily or placebo. All patients and investigators were masked to treatment assignment. The primary endpoint was a composite of doubling of serum creatinine (sustained for >= 30 days) or end-stage kidney disease (eGFR = 90 days, chronic dialysis for >= 90 days, kidney transplantation, or death from kidney failure) in the intention-to-treat population of all responders. Safety was assessed in all patients who received at least one dose of their assigned study treatment. The study is registered with ClinicalTrials. gov, number NCT01858532.Findings Between May 17, 2013, and July 13, 2017, 11 087 patients were screened; 5117 entered the enrichment period, and 4711 completed the enrichment period. Of these, 2648 patients were responders and were randomly assigned to the atrasentan group (n=1325) or placebo group (n=1323). Median follow-up was 2.2 years (IQR 1.4-2.9). 79 (6.0%) of 1325 patients in the atrasentan group and 105 (7.9%) of 1323 in the placebo group had a primary composite renal endpoint event (hazard ratio [HR] 0.65 [95% CI 0.49-0.88]; p=0.0047). Fluid retention and anaemia adverse events, which have been previously attributed to endothelin receptor antagonists, were more frequent in the atrasentan group than in the placebo group. Hospital admission for heart failure occurred in 47 (3.5%) of 1325 patients in the atrasentan group and 34 (2.6%) of 1323 patients in the placebo group (HR 1.33 [95% CI 0.85-2.07]; p=0.208). 58 (4.4%) patients in the atrasentan group and 52 (3.9%) in the placebo group died (HR 1.09 [95% CI 0.75-1.59]; p=0.65).Interpretation Atrasentan reduced the risk of renal events in patients with diabetes and chronic kidney disease who were selected to optimise efficacy and safety. These data support a potential role for selective endothelin receptor antagonists in protecting renal function in patients with type 2 diabetes at high risk of developing end-stage kidney disease.

Jahnke, H. N., & Hefendehl-Hebeker, L. (Eds.). (2019). Traditions in German-speaking mathematics education reserach (ICME-13 Monographs). Cham: Spinger Open, , pp. 61-89., Considering mathematics education as a DESIGN SCIENCE has strong roots in Germany. E. Ch. Wittmann in particular contributed to the establishment of this approach. From a DESIGN SCIENCE perspective, substantial learning environments play a crucial role. They comprise mathematical tasks which are connected in an operative way, indicative of a specific epistemological structure. In such substantial learning environments, students are actively immersed in learning mathematics, and the learning environments allow for the pursuit of individual and differentiated learning processes. In this chapter, we first address the scope of Design Science and pay attention to characteristics of the learning environments and how teaching experiments can be conducted. We then focus on key ideas and their role as a design principle. In the next section, we provide a comprehensive example of designing a learning environment. Lastly, we shift our attention to the Design Research approach, which complements designing substantial learning environments by empirically studying the initiated learning processes to gain evidence for both theoretical considerations and design principles.

Abstract

Adequate fresh water availability is an important factor for human security in many parts of the world. In transboundary river basins, decreased water supply due to local environmental change and global climate change and increased water demand due to growing populations and continued economic development can aggravate water scarcity. Contrary to the claim that water scarcity may result in an increased risk of armed conflict, there is no simple relationship between freshwater availability and violent conflict. Other crucial factors need to be taken into consideration that also directly influence resource availability and personal human well-being. In this review, we assess the scientific literature on conflict and cooperation in transboundary river systems. Most international river basins are already jointly managed by the riparians, but successful management in times of climate change necessitates the inclusion of more factors besides mere allocation schemes. On the basis of a substantial body of literature on the management of transboundary watersheds, an analytical framework of the water-security nexus is developed that integrates the physical and socioeconomic pathways connecting water availability with conflict or cooperation. This framework is subsequently applied to two transboundary river basins—the Nile River and the Syr Darya/Amu Darya—as they represent two world regions that could become future water hot spots. An improved understanding of the developments leading to water conflicts and their interaction can help to successfully reduce the risk of water conflicts in these regions and to move toward increased cooperation among the riparians of transboundary river systems.

Abstract

Microscopic organisms with uncertain systematic affinity are referred to in the paleontological literature as microproblematica. Notwithstanding their cryptic biology, some are valuable index fossils for the facies analysis of reefal carbonates. Within reefal carbonates exposed near the town of Saklikent, Taurus Mountains, southern Turkey, many microproblematic organisms were found in thin-sections. All of these organisms are known from similar Norian–Rhaetian carbonates from other localities of the Tethys. They are briefly described here and their occurrence, abundance, and stratigraphic range, and their importance as facies and index fossils, are discussed, as well as their original interpretation. Some of these microproblematica are described for the first time from the Norian–Rhaetian interval of Turkey. A list of all known Triassic microproblematica, formal and informal taxa, is given as an appendix.

Abstract

Die Digitalisierung der Arbeitswelt verandert die traditionelle Wertschopfung in Unternehmen nachhaltig. Die Ubernahme von Arbeitsaufgaben, Dienstleistungen oder die Generierung von Ideen konnen uber Online-Plattformen weltweit an eine Gruppe von Interessierten, sog. Crowdworker, angeboten bzw. ausgelagert werden. Genauso lange wie dieses Phanomen des Crowdworking existiert, wird es kontrovers diskutiert. Insbesondere die (arbeits-)rechtlichen Beziehungen in dem Dreiecksverhaltnis (Plattform, Crowdworker und Unternehmen) werfen Fragen auf, die in diesem Beitrag aufgezeigt und diskutiert werden.

Abstract

Deterministic model updating is now a mature technology widely applied to large-scale industrial structures. It is concerned with the calibration of the parameters of a single model based on one set of test data. It is, of course, well known that different analysts produce different finite element models, make different physics-based assumptions, and parameterize their models differently. Also, tests carried out on the same structure, by different operatives, at different times, under different ambient conditions produce different results. There is no unique model and no unique data. Therefore, model updating needs to take account of modeling and test-data variability. Much emphasis is now placed on what has become known as stochastic model updating where data are available from multiple nominally identical test structures. In this paper two currently prominent stochastic model updating techniques (sensitivity-based updating and Bayesian model updating) are described and applied to the DLR AIRMOD structure.

Abstract

Verglichen mit den Risiken und Konflikten des fossil-nuklearen Zeitalters erscheinen die erneuerbaren Energien in einem überwiegend positiven Licht. Allerdings schafft die Transformation zu einer kohlenstoffarmen Energieversorgung neue Energielandschaften, die einen hohen Bedarf an Landflächen mit sich bringen – was ebenfalls Energiekonflikte provozieren kann. Um derartige Konflikte zu mindern und die Akzeptanz der Bevölkerung zu gewinnen, kann Technikfolgenabschätzung einen Beitrag leisten, wenn sie sich auf räumliche agentenbasierte Modelle stützt. Diese Modelle repräsentieren die Entscheidungen von Stakeholdern über Energiealternativen, deren dynamische Interaktionen sowie daraus resultierende Landnutzungsoptionen und Energiepfade. Als Fallstudie dient Norddeutschland, wo Landwirte und Gemeinden als lokale Akteure der Energiewende agieren. The risks and conflicts of the fossil-nuclear age are in contrast to the effects of renewable energies which appear in a largely positive light. However, the transformation towards a low-carbon energy supply creates new energy landscapes with a high demand for suitable land areas – which may also provoke energy conflicts. Technology assessment can contribute to reducing such energy conflicts and increasing public acceptance by using spatial agent-based models that represent dynamic decisions and interactions of stakeholders regarding energy alternatives and land-use options. Northern Germany serves as a case study region where farmers and communities are local actors of the energy transition.
