Institutionalised amnesia? Exploring geographies of memory and the care of German graves in Central Europe: insights from the Czech Republic
Authors: Novotný Lukáš 
Published: February 2025

Abstract
The care of German tombs and graves remains a sensitive and complex issue in Central Europe, particularly in the Czech Republic. This study adopts a historical–geographical approach to explore German cemeteries and graves as significant memory landscapes. Specifically, it investigates the current state of German cemeteries in the Czech Republic, identifies forms of devastation, and examines the tools available to burial ground operators for their maintenance. The theoretical framework draws upon the concepts of lieux de mémoire (sites of memory) and a metaphorical understanding of memory landscapes. Empirically, the study involves on-site visits to cemeteries and the implementation of semi-structured interviews in three case study regions within the country. The findings contribute to a proposal for measures aimed at preserving and caring for abandoned German cemeteries, taking into account ongoing scholarly debates on the geography and politics of memory. Among the key recommendations is the establishment of a subsidy programme to support, even symbolically, the rehabilitation of graves of significant historical figures. Additionally, the development of a methodological guide is proposed to assist mayors and other burial ground operators in addressing practical challenges related to the care and restoration of these graves.

Abstract
North Carolina (NC) actively participates in the Fulbright Scholar program, a premier educational and cultural exchange initiative established in 1946 by the United States. The program provides opportunities for passionate and accomplished scholars from NC to visit over 160 countries and for NC institutions to host faculty professionals from around the world in diverse disciplines. This study aims to meta-synthesize the NC Fulbright database to decipher the spatial patterns of local institutes that have benefitted from the Fulbright program. Data were extracted from the Fulbright Scholar directory and split into three quarter-century periods (1949–1975, 1975–2000, and 2000–2024) across two spatial domains: worldwide and statewide. Cartographic methods were used to visualize these spatio-temporal patterns. The trend analysis reveals that the mean number of U.S. scholars who went abroad from the state increased from 12 (1949–1975) to 41 (2000–2024), with a doubling of countries travelled to (from 53 to 110 countries). While scholars from the state travelled all major continents, cultural exchanges with the global south, especially culturally diverse central African countries, were limited. Over the years, there has been a shift in the choice of world regions and disciplines away from developed European countries for Literature, History, and Political Science disciplines to emerging countries for Education, Engineering, and Law disciplines. The state has consistently received about 20 visiting scholars every year, primarily from emerging nations such as India, China, South Korea, and Argentina to the major universities in the Triangle region—such as the University of North Carolina-Chapel Hill, Duke University, and North Carolina State University—these institutes continue to dominate both U.S. Scholar and Visiting Scholar fellowships (about 75%) in the state. This study underscores the need for a diverse approach in awarding U.S. Fulbright program opportunities, especially to the Historically Black Colleges and Universities, to enhance international educational and cultural exchange, especially with the global south.
Productivity slowdown and regional productivity heterogeneity

Published: February 2025

Abstract
This paper examines the productivity slowdown by analyzing the degree, leverage, and spatial patterns of productivity improvements and spillovers in regions of France, Germany, Italy, and Spain. The analysis covers the Global Financial Crisis (2007–2012) as well as the pre-crisis (2002–2007) and post-crisis (2012–2017) periods. Using the Metafrontier Malmquist Productivity approach with robust estimators, the study conceptualizes technological shifts and diffusion networks within both endogenous and exogenous regional environments. Findings show that changes in technical efficiency have a short-term positive effect on regional growth, while technical change affects growth through initial conditions and path dependency. Regional productivity shifted from improving within-country resource allocation via endogenous factors enhancing the exogenous operating environment. However, unlocking a region’s full productivity potential depends on factors beyond its development level. Diffusion networks for efficiency and technological advancements exhibit limited dynamism and region-specific characteristics. In some cases, productivity growth in one region negatively affects neighboring regions. Spillovers from efficiency improvements occur partially among regions with closer technological proximity, especially during crises. These insights offer important policy implications for fostering regional productivity and addressing uneven development.

Abstract
The coat color of the swamp buffalo is commonly dark gray, while the white coat color variant, which may have potential heat stress advantages, is also present in some Asian countries, including Vietnam. This study analyzed the most likely candidate genes, ASIP and TYR, responsible for the white coat color of Vietnamese native buffaloes. We found that LINE1 insertion in ASIP, a mutation previously reported in white swamp buffalo from other Asian countries, was exclusively found in white Vietnamese buffalo. Moreover, significantly higher expression of ASIP was confirmed in the hair follicles of white buffalo. On the other hand, no variants associated with the white phenotype were found in TYR. These findings indicate that the LINE1 insertion in ASIP is responsible for the white coat color in Vietnamese native buffalo, and that provides a crucial step towards their utilization and improved productivity in Vietnam.

Abstract
Bird populations face many threats worldwide, including collisions with anthropogenic structures such as buildings’ windows. Bird-window collisions are gaining attention, but research and mitigation often face barriers including collision surveying guidelines, funding availability, and retrofitting costs and approvals. Beginning in 2022, we conducted research about bird-window collisions on an urban university campus to engage students in research and inform the implementation of mitigation at the site(s) with the most collisions. To achieve these goals, we worked with undergraduate and graduate students, faculty, staff, administrators, and media personnel to monitor bird-window collisions, spread the word throughout the community, and advocate for retrofitting buildings. Research was incorporated into a course-based undergraduate research experience, several undergraduate directed studies, paid undergraduate research positions, and volunteer opportunities. By the end of 2024, bird-friendly window markers were installed on two buildings on campus. In this article, we present the collective reflections and lessons learned from university stakeholders involved in the project. We recommend that similar conservation projects on university campuses (1) maximize project flexibility and consider how to best support stakeholders; (2) build impact and momentum over time by engaging stakeholders in unique ways; and (3) leverage participants’ previous experiences and use a solution-focused approach to ensure that participation is motivating and rewarding. With our lessons learned, similar projects on other university campuses may be able to attain more success in student engagement, project outcomes, and ultimately, the implementation of bird-friendly practices.
Minima Trivialia Bypassed
Authors: Salis Pietro 
Published: February 2025

Abstract
Peirce’s pragmatist theory of truth holds that truth will be the outcome of an indefinitely adequate amount of scientific research. According to the minima trivialia objection, Peirce’s theory of truth is refuted by such common sense truths as that about what I ate for breakfast, which is hardly the outcome of a prolonged collective scientific endeavour. The argument does not work, however, if we endorse Sellars’s distinction between the manifest image and the scientific image of mankind in the world and the connected scientific realism: in this Sellarsian context, minima trivialia can be seen as false views from the perspective of the manifest image, like the existence and persistence of material objects, and not as proper truths, which are appreciated as such only from the point of view of the scientific image. Therefore, the endorsement of this distinction, which is quite compatible with Peirce’s framework, bypasses the minima trivialia objection.
Fiber Bragg Grating Sensor Embedding and Temperature Monitoring in Die-Casting Molds Using Directed Energy Deposition
Authors: Jang Jihoon , Baek Gyeong-Yun 
Published: February 2025

Abstract
Die casting is a widely used precision casting method. In die casting, the injection and mold temperatures affect the fluidity during casting and cooling. However, because the temperature characterization of die-casting molds is conducted fragmentarily using thermocouples and thermal imaging cameras, a fundamental solution is needed to ensure the reliability of the temperature data. In this study, real-time multipoint temperature measurements were conducted by embedding a seamless tube into an AISI-H13 specimen using Directed Energy Deposition. The interface of the deposited layer and H13 substrate was subsequently observed via Scanning Electron Microscope (SEM). Real-time temperature monitoring according to the embedding depth was conducted by inserting fiber Bragg grating (FBG) sensors into the specimen, followed by mechanical property testing. The temperature sensitivity and stabilization did not significantly differ within the 1-3 mm depth range, thus confirming that the temperatures at multiple points could be measured in real time. The SEM images revealed no porosity at the interface. Compared with that of the original material, the tensile strength of the deposited layer improved. Furthermore, because the interface hardness of H13 exceeds that of 50 HRC, which is commonly used in die casting, FBG sensors could also be applied to industrial die-casting molds.
In Situ Spray Bead Acquisition and Analysis for Coating Thickness Predictions
Authors: Hudomalj Uroš , Aschwanden Ivo , Weiss Lukas , Nabavi Majid , Wegener Konrad 
Published: February 2025

Abstract
Coating thickness is considered to be one of the most important characteristics of thermal spray coatings. Therefore, it has long been the goal to be able to predict the coating thickness that ensues when coating an arbitrary part. A commonly applied approach is to determine the coating deposit based on a series of spray spot tests and use that for modeling the coating. Another option is to conduct spray bead tests, which better reflect the conditions during the coating. This work suggests a novel approach for in situ acquisition of the spray beads and their analysis. The acquisition is based on a 3D camera to scan the sample before and after depositing of a spray bead. The approach allows for their streamlined evaluation, enabling better understanding of spray bead formation and their modeling. The suggested analysis of spray beads includes uncertainty evaluation. This enables estimation of model prediction uncertainties which has been omitted in the previous works on the topic. The analysis shows that a relative expanded uncertainty of 10% (at 95% level of confidence) can be expected for the coating thickness prediction for the simplest scenario of coating a flat sample sprayed perpendicularly at a constant spray distance and spray speed.
A Review of Polynomial Matrix Collocation Methods in Engineering and Scientific Applications
Authors: Çevik Mehmet , Savaşaneril Nurcan Baykuş , Sezer Mehmet 
Published: February 2025

Abstract
Ordinary, partial, and integral differential equations are indispensable tools across diverse scientific domains, enabling precise modeling of natural and engineered phenomena. The polynomial collocation method, a powerful numerical technique, has emerged as a robust approach for solving these equations efficiently. This review explores the evolution and applications of the collocation method, emphasizing its matrix-based formulation and utilization of polynomial sequences such as Chebyshev, Legendre, and Taylor series. Beginning with its inception in the late 20th century, the method has evolved to encompass a wide array of differential equation types, including integro-differential and fractional equations. Applications span mechanical vibrations, heat transfer, diffusion processes, wave propagation, environmental pollution modeling, medical uses, biomedical dynamics, and population ecology. The method’s efficacy lies in its ability to transform differential equations into algebraic systems using orthogonal polynomials at chosen collocation points, facilitating accurate numerical solutions across complex systems and diverse engineering and scientific disciplines. This approach circumvents the need for mesh generation and simplifies the computational complexity associated with traditional numerical methods. This comprehensive review consolidates theoretical foundations, methodological advancements, and practical applications, highlighting the method’s pivotal role in modern computational mathematics and its continued relevance in addressing complex scientific challenges.
Fractal wood burning remains a potentially lethal recreational activity
Authors: Byard Roger W. , Langlois Neil E. I. 
Published: February 2025

Abstract
Fractal burning is a recent form of pyrography (decorative wood burning) using an extremely high voltage applied across a wood surface soaked in an electrolyte solution to produce a ferning or ‘Lichtenberg’ pattern. Two fatal cases of electrocution are reported in adults engaged in fractal burning to demonstrate characteristic features. Both had evidence of electrical contact with extensive burning. Death can occur following accidental contact with electrodes, the electrolyte solution or a loose wire, or when the victim stands on a conductive floor, or does not wear appropriate protective clothing, or has the wood on a non-insulated surface. Investigators need to check for these issues and to also determine whether the decedent had been appropriately trained in the handling of high voltage equipment.

Authors: Tanriverdi Ozgur 
Published: February 2025

Abstract
Authorship in clinical research carries significant academic, financial, and social implications. However, determining rightful authorship often introduces ethical and professional dilemmas, particularly in large, multidisciplinary studies, such as those common in oncology. This article explores the ethical complexities surrounding authorship in clinical research from the viewpoint of a medical oncologist. It addresses issues, such as academic jealousy, the inclusion of industry-affiliated researchers, honorary authorship, and the role of patient recruitment in authorship qualification. By examining current guidelines, ethical considerations, and practical cases, this paper aims to offer insights into fostering fair and transparent authorship practices in the field of clinical oncology.

Der folgende Beitrag widmet sich diesem Kontinuum und führt zudem in den Schwerpunkt ‚Can the voice of children be heard?‘ ein.
Construction and initial validation of an academic impostor syndrome measure
Authors: Todd Valerie J. , Mcilroy David 
Published: February 2025

Abstract
Impostor syndrome has been identified as a growing problem in professional and academic settings. It has been associated with diminished confidence and inhibited performance. In the context of education, it has been reported as maladaptive to enrolment, retention, integration, wellbeing, and academic performance. One inhibiting factor is the lack of validated measures specific to education. Hence, the primary aim and original contribution of this study is the construction and initial validation of such a measure. This construction process was initially informed by a trawl of the literature on general impostor syndrome, with ten domains emerging from the reviews to provide content validity. Items were constructed in consultation with students as end users and academics from national and international symposia and seminars. The studies were carried out at two UK higher education institutions, with N = 339 undergraduates. Through iterative processes including item analysis, principal component analysis, and factor analyses, ten items were selected from a pool of thirty. These covered the ten literature domains and associated with good factor loadings (> 0.45) and sound model fit indicators. Invariance testing of both student groups demonstrated equivalence of factor structure and factor loadings. To enhance the measure’s validity, the Five-Factor Model of Personality, Self-esteem, and Self-efficacy were included. The moderate correlations of these factors with academic impostor syndrome in expected directions may respectively signpost the approach and avoidance behaviours that counter or nurture the problem. The new measure is commended as a potentially useful tool for research and practice.

Abstract

Purpose of Review
Cartilage injury does not heal spontaneously. The current cell-based cartilage treatments have either demonstrated poor clinical outcomes, require two surgeries, or are costly and logistically challenging. To overcome these challenges, our team has developed a one-stage, two cell-type surgical cell therapy for acute chondral defects. This procedure combines allogeneic mesenchymal stromal cells (MSCs) and autologous chondrons to harness MSCs as signaling cells to stimulate chondrons to promote tissue repair. This procedure has been investigated in clinical trials conducted in both Europe and the United States which are called IMPACT and RECLAIM, respectively. This article provides a review of our preclinical and clinical research which led to the development of this cell therapy.

Recent Findings
The combination of allogeneic MSCs and autologous chondrons in preclinical studies have demonstrated to synergistically stimulate cartilage repair, and the combination of cells outperforms either cell-type alone. In clinical trials, the combined cell therapy was safe to use, improved knee function, and demonstrated durable pain reduction.

Summary
Our single-stage, combined cell therapy of allogeneic MSCs and autologous chondrons is a viable cell therapy for acute articular cartilage defects. We anticipate this combined cell therapy may be a platform cell therapy for a wide range of musculoskeletal repair applications.
Economic Performance of Potato Crops Dependent on Variety Specific Seed Piece Weight and Uniformity Within a Seed Lot
Authors: Hintze Alexa , Holden Zachary J. , Pavek Mark J. 
Published: February 2025

Abstract
Quality seed of the ideal size and type (i.e., whole-seed tubers or cut seed pieces) is critical in achieving uniform plant stands and optimal economic returns in commercial potato production. A survey assessed the performance of commercial seed cutting operations during 2021–22 to document the range of seed piece sizes planted in Washington. In addition, two field trials examined seed size performance (28, 42, 56, 70, 84, and 98 g (1.0, 1.5, 2.0, 2.5, 3.0, 3.5 oz)) for Clearwater Russet, Ranger Russet, and Russet Burbank. Seed type performance (whole vs cut) was also assessed for Clearwater Russet. As seed size increased from 28 to 98 g for all varieties and seed types, early plant growth generally improved, average tuber weight decreased by 22%, and stem and tuber number per plant increased by 77% and 50%, respectively. Cut Clearwater Russet seed produced 7% higher yields and 5% more economic return than whole seed. Economic return peaked for Clearwater Russet with a seed weight of 56 g (2.0 oz). Economic return of Ranger Russet and Russet Burbank peaked when seed size was between 70–84 g (2.5 to 3.0 oz) for Russet Burbank and at 84 g (3.0 oz) for Ranger Russet. Due to a highly variable range in cut seed size found in the commercial seed lot survey, growers may have lost an estimated $297 ha−1 or $15,000 pivot−1 (51 ha) during 2021–22 compared to a hypothetical potato field planted with uniform, economically optimal, seed sizes. We conclude that growers should target adequate seed sizes and minimize under- and oversized seed pieces to produce the highest economic return for each variety.
