Published: March 2024

AbstractPredictive breeding approaches, like phenomic or genomic selection, have the potential to increase the selection gain for potato breeding programs which are characterized by very large numbers of entries in early stages and the availability of very few tubers per entry in these stages. The objectives of this study were to (i) explore the capabilities of phenomic prediction based on drone-derived multispectral reflectance data in potato breeding by testing different prediction scenarios on a diverse panel of tetraploid potato material from all market segments and considering a broad range of traits, (ii) compare the performance of phenomic and genomic predictions, and (iii) assess the predictive power of mixed relationship matrices utilizing weighted SNP array and multispectral reflectance data. Predictive abilities of phenomic prediction scenarios varied greatly within a range of − 0.15 and 0.88 and were strongly dependent on the environment, predicted trait, and considered prediction scenario. We observed high predictive abilities with phenomic prediction for yield (0.45), maturity (0.88), foliage development (0.73), and emergence (0.73), while all other traits achieved higher predictive ability with genomic compared to phenomic prediction. When a mixed relationship matrix was used for prediction, higher predictive abilities were observed for 20 out of 22 traits, showcasing that phenomic and genomic data contained complementary information. We see the main application of phenomic selection in potato breeding programs to allow for the use of the principle of predictive breeding in the pot seedling or single hill stage where genotyping is not recommended due to high costs.

Published: March 2024

AbstractUltrasonic-assisted drilling (UAD) is a machining process that is known to improve the hole quality and reduce cutting forces. Previous studies focused on optimizing cutting parameters to improve the hole quality in conventional drilling (CD) and UAD, as well as to finding the optimum vibration parameters (frequency and amplitude) that will increase the effectiveness of the UAD process. However, the influence of cutting tool type during UAD has been largely overlooked. This research aims to address this gap by analyzing the effect of cutting tool type during UAD on the cutting forces and hole quality in GLARE (Glass Laminate Aluminum-Reinforced Epoxy) laminates. Four types of drills, namely, twist drill (TD), double cone drill (DCD), a step drill type 1 (SD1), and step drill type 2 (SD2) with different step length, were selected for this study. The lowest thrust force (47.04 N) and torque (0.079 Nm) were achieved using twist drill, while DCD, SD1, and SD2 exhibited higher thrust forces (12.81%, 20.69%, 41.3%) and torques (94%, 92%, 91%), respectively. In addition, TD produced high-quality holes with lowest surface roughness (Ra 1.66 μm, Rz 10.58 μm) and minimal burr formation (entry burr height 152.3 μm, exit burr height 69.22 μm). Conversely, DCD, SD1, and SD2 showed higher surface roughness Ra (23%, 16%, 24%) and Rz (16%, 37%, 29%), respectively, compared to the TD. Holes drilled using SD1 and SD2 generally had smaller burr height. Overall, UAD system effectively reduced cutting forces at low spindle speed and feed rate. To achieve higher drilling quality, specifically to reduce the surface roughness and exit burr height, a medium spindle speed of 3000 rpm, a feed rate of 225 mm/min is recommended. Drilling at higher cutting parameters using UAD resulted in a decline in hole quality, except for entry burr height.
Vision based trajectory dynamic compensation system of industrial robot

Published: March 2024

AbstractThis study aims to enhance the flexibility of robots in the manufacturing process to meet the growing demand for flexible manufacturing systems by constructing a dynamic compensation system. The system enables the end effector of the robot to track the trajectory contour on the horizontal plane, even if there is a deviation between the teaching trajectory and the target trajectory contour. The proposed system employs an innovative mechanism design and algorithm that enables dynamic compensation of the robot’s absolute position in the XY-plane, even when the end effector is obstructed. The system uses an XY-stage and two industrial cameras, with each axis being separately controlled. To detect and compensate for errors in the end effector and target trajectory, the two cameras are aligned with the X- and Y-direction linear stage, respectively. The cameras are fixed with respect to the linear stage, and the end effector is placed on the stage work surface. Unlike traditional stereo cameras, the cameras in this system do not require calibration for their positional relationship. To verify the system’s effectiveness, this study set a group of teaching and target trajectory contours with a maximum deviation of over than 8 mm. Under the compensation of the system, the maximum error between the end effector and the target trajectory contour was 22.8 pixels (1.34 mm), with an average absolute error of 5.4 pixels (0.32 mm). Compared to the maximum error of 8.45 mm before compensation, the error has been reduced by 84 %.
Adiabatic Evolution of Low-Temperature Many-Body Systems
Authors: Greenblatt Rafael L. , Lange Markus , Marcelli Giovanna , Porta Marcello 
Published: March 2024

AbstractWe consider finite-range, many-body fermionic lattice models and we study the evolution of their thermal equilibrium state after introducing a weak and slowly varying time-dependent perturbation. Under suitable assumptions on the external driving, we derive a representation for the average of the evolution of local observables via a convergent expansion in the perturbation, for small enough temperatures. Convergence holds for a range of parameters that is uniform in the size of the system. Under a spectral gap assumption on the unperturbed Hamiltonian, convergence is also uniform in temperature. As an application, our expansion allows us to prove closeness of the time-evolved state to the instantaneous Gibbs state of the perturbed system, in the sense of expectation of local observables, at zero and at small temperatures. As a corollary, we also establish the validity of linear response. Our strategy is based on a rigorous version of the Wick rotation, which allows us to represent the Duhamel expansion for the real-time dynamics in terms of Euclidean correlation functions, for which precise decay estimates are proved using fermionic cluster expansion.
To Approve or not to Approve? A Comparative Analysis of State-Company-Indigenous Community Interactions in Mining in Canada and Sweden

Published: March 2024

AbstractThis Special Section explores the interplay between Indigenous peoples, industry, and the state in five proposed and active mining projects in Canada and Sweden. The overall aim is to identify factors shaping the quality of Indigenous community-industry-state interactions in mining and mine development. An ambition underlying the research is to develop knowledge to help manage mining related land-use conflicts in Sweden by drawing on Canadian comparisons and experience. This paper synthesizes the comparative research that has been conducted across jurisdictions in three Canadian provinces and Sweden. It focuses on the interplay between the properties of the governance system, the quality of interaction and governance outcomes. We combine institutional and interactive governance theory and use the concept of governability to assess how and why specific outcomes, such as mutually beneficial interaction, collaboration, or opposition, occurred. The analysis suggests there are measures that can be taken by the Swedish Government to improve the governability of mining related issues, by developing alternative, and more effective, avenues to recognize, and protect, Sámi rights and culture, to broaden the scope and increase the legitimacy and transparency of the EIAs, to raise the quality of interaction and consultation, and to develop tools to actively stimulate and support collaboration and partnerships on equal terms. Generally, we argue that Indigenous community responses to mining must be understood within a larger framework of Indigenous self-determination, in particular the communities’ own assessments of their opportunities to achieve their long-term objectives using alternative governing modes and types of interactions.
Untersuchung der Genauigkeit klinischer Diagnosen von Neoplasien der Konjunktiva
Authors: Gruben Arved Rikus , Hösel Kristin , Roider Johann , Ehlken Christoph 
Published: March 2024

Zusammenfassung
Hintergrund
Neoplasien der Bindehaut umfassen eine Vielzahl verschiedener Entitäten mit jeweils unterschiedlicher klinischer Präsentation. Diese sind anhand klinischer Merkmale nicht immer eindeutig voneinander zu unterscheiden. Die R0-Resektion stellt den Goldstandard für die meisten malignen Tumoren der Bindehaut dar, aber nicht jede benigne Läsion muss mittels Exzision behandelt werden. Im klinischen Alltag muss häufig ein konservatives Vorgehen gegen eine operative Exzision abgewogen werden.

Ziel
Ziel dieser Arbeit war es, die Genauigkeit klinischer Diagnosen bei Neoplasien der Bindehaut zu ermitteln.

Methoden
In einer retrospektiven Untersuchung wurden im Zeitraum zwischen 2011 und 2020 die Daten aller Patienten nach Exzision eines Bindehautbefundes, die an der Klinik für Ophthalmologie am UKSH Campus Kiel operiert wurden, extrahiert und ausgewertet. Es wurde jeweils die Spezifität, Sensitivität und der positive und negative Vorhersagewert für die präoperative klinische Einschätzung der Dignität und die diagnostische Gruppe anhand des histopathologischen Befundes ermittelt.

Ergebnisse
Von 220 eingeschlossenen Fällen waren nach histologischer Beurteilung 75 % benigne, 25 % maligne. Die häufigste Neoplasie war der benigne Bindehautnävus (12,3 %). Die Sensitivität für die klinische Vorhersage einer benignen Läsion lag bei 0,86 (95%-Konfidenzintervall [95%-KI] 0,59–0,92), die Spezifität bei 0,95 (95%-KI: 0,85–0,99) und der positive Vorhersagewert bei 0,98 (95%-KI: 0,94–1,0). Die Sensitivität für die klinische Vorhersage maligner Dignität ergab 0,95 (95%-KI: 0,85–0,99), Spezifität 0,88 (95%-KI: 0,83–0,93) und der positive Vorhersagewert 0,73 (95%-KI: 0,61–0,83).

Schlussfolgerung
Die ermittelten Werte für die klinische Diagnose sind als gut zu bewerten. Dennoch sollte im klinischen Alltag, insbesondere bei untypischen Läsionen, die Verdachtsdiagnose kritisch überprüft werden und im Zweifel eine Exzision angestrebt werden.

Abstract
Purpose
To describe the epidemiology, clinical features, and classification of uveitis in a large cohort of Colombian patients.

Methods
Data were collected from seven ophthalmological referral centers in the four main cities in Colombia. The study included patients with a confirmed diagnosis of uveitis from January 2010 to December 2022. Information on demographics, ophthalmic examination findings, uveitis classification, and etiology was recorded.

Results
The study reviewed 3,404 clinical records of patients with uveitis. The mean age at diagnosis was 41.1 (SD 19.0) years, and 54.2% of the patients were female. Overall, 1,341(39.4%) were infectious, 626 (18.4%) non-infectious, and four masquerade syndromes (0.1%). The most common types of uveitis were unilateral (66.7%), acute (48.3%), and non-granulomatous (83%). Anterior uveitis was the most common anatomical localization (49.5%), followed by posterior uveitis (22.9%), panuveitis (22.3%), and intermediate uveitis (5.2%). A diagnosis was established in 3,252 (95.5%) cases; idiopathic was the most common cause (27.7%), followed by toxoplasmosis (25.3%) and virus-associated uveitis (6.4%). The age group between 30 and 50 exhibited the highest frequency of uveitis.

Conclusion
This multicenter study comprehensively describes uveitis characteristics in Colombian patients, providing valuable insights into its demographic and clinical features. The study findings emphasize the need to continue updating the changing patterns of uveitis to improve diagnosis and treatment strategies for diseases associated with intraocular inflammation.

Abstract
Objective
To assess the degree of openness of communication about illness and death between patients with advanced cancer and their relatives during the last three months of the patient’s life, and its association with relatives’ characteristics and bereavement distress.

Methods
We used data from bereaved relatives of patients with advanced cancer from the prospective, longitudinal, multicenter, observational eQuipe study. Univariate and multivariable linear regression analyses were used to assess the association between the degree of openness of communication (measured using the validated Caregivers’ Communication with patients about Illness and Death scale), the a priori defined characteristics of the relatives, and the degree of bereavement distress (measured using the Impact of Event Scale).

Results
A total of 160 bereaved relatives were included in the analysis. The average degree of open communication about illness and death between patients with advanced cancer and their relatives was 3.86 on a scale of 1 to 5 (SE=0.08). A higher degree of open communication was associated with a lower degree of bereavement distress (p=0.003). No associations were found between the degree of open communication and the relatives’ age (p=0.745), gender (p=0.196), level of education (p>0.773), (religious) worldview (p=0.435), type of relationship with the patient (p>0.548), or level of emotional functioning before the patient’s death (p=0.075).

Conclusions
Open communication about illness and death between patients and relatives seems to be important, as it is associated with a lower degree of bereavement distress. Healthcare professionals can play an important role in encouraging the dialogue. However, it is important to keep in mind that some people not feel comfortable talking about illness and death.

Published: March 2024

AbstractDaily maximum, TX, and minimum, TN, temperatures recorded at Fabra Observatory, for the period 1914–2020 (from June to September), have permitted to identify the daytime and night time heatwaves, HWs, at the Barcelona Metropolitan Region, BMR, along 107 years. Four heatwaves indices have been computed both for maximum and minimum temperatures: the number of events per season, HWN; their maximum duration, HWD; their frequency of occurrence, HWF; and the amplitude of the hottest day event, HWA. Trends in these indices have been obtained and their statistical significance quantified by means of the Mann-Kendall test. For the whole period (1914–2020), positive significant trends have been detected for the four indices, with a marked positive trend since year 2000 for TX, and since 1985 for TN. Nevertheless, when 31-year moving windows have been analysed, both positive and negative significant trends are obtained, being remarkable the change in trend signs around 1960s. The convenience of using the four HW indices is evaluated applying a Principal Component Analysis, PCA, obtaining two principal components. Additionally, the spatial distributions of the MODIS land surface temperatures, LST, corresponding to some extreme heatwaves, permits the detection of two hotspots in the BMR, one for TX and the other for TN. It is also worth mentioning that correlations between the Western Mediterranean Oscillation index, WeMOi, and HW episodes are detected, being notable that, at the beginning of these episodes, WEMOi values are usually lower. These correlations could improve the HWs forecasting.
An augmented reality approach for communicating intangible and architectural heritage through digital characters and scale models
Authors: Galani Sophie , Vosinakis Spyros 
Published: March 2024

AbstractIntangible cultural heritage (ICH) represents living cultural expressions and practices that are part of the heritage of a community, and their preservation and transmission are considered highly important. Various methods and tools have been applied so far for the digitization and dissemination of ICH content including a wide range of technologies. Mobile augmented reality is a promising solution along this path that enables the overlap of digital and real-world information in an engaging and efficient manner. Despite the widespread use of AR in cultural heritage, there are not many studies regarding the user experience, the learning outcomes, and the way in which users observe and interact with the virtual content. This paper presents a mobile augmented reality installation that re-enacts the stages of leather tanning process, adopting a novel approach that augments 3D content upon a physical scale model of an old tannery. This approach pursues to transmit the cultural value of traditional craftmanship to visitors of the building and associate its architectural elements to its history and use. A user evaluation was conducted aiming to measure the users’ engagement, learning, and experience using the installation. The encouraging results led to a follow-up study about the impact of the physical scale model on the experience. Two variations of the experience have been studied, one with a physical scale model and one with a digital-only version in a between-subject design. The results of the two studies provide evidence that the proposed approach generated a positive user experience and evident learning gain and was considered easy to use, highlighting its potential to be widely adopted in buildings with architectural value.
A color Passthrough mixed reality application for learning piano
Authors: Banquiero Mariano , Valdeolivas Gracia , Ramón David , Juan M.-Carmen 
Published: March 2024

AbstractThis work presents the development of a mixed reality (MR) application that uses color Passthrough for learning to play the piano. A study was carried out to compare the interpretation outcomes of the participants and their subjective experience when using the MR application developed to learn to play the piano with a system that used Synthesia (N = 33). The results show that the MR application and Synthesia were effective in learning piano. However, the students played the pieces significantly better when using the MR application. The two applications both provided a satisfying user experience. However, the subjective experience of the students was better when they used the MR application. Other conclusions derived from the study include the following: (1) The outcomes of the students and their subjective opinion about the experience when using the MR application were independent of age and gender; (2) the sense of presence offered by the MR application was high (above 6 on a scale of 1 to 7); (3) the adverse effects induced by wearing the Meta Quest Pro and using our MR application were negligible; and (4) the students showed their preference for the MR application. As a conclusion, the advantage of our MR application compared to other types of applications (e.g., non-projected piano roll notation) is that the user has a direct view of the piano and the help elements appear integrated in the user’s view. The user does not have to take their eyes off the keyboard and is focused on playing the piano.
Level constrained first order methods for function constrained optimization
Authors: Boob Digvijay , Deng Qi , Lan Guanghui 
Published: March 2024

Abstract
We present a new feasible proximal gradient method for constrained optimization where both the objective and constraint functions are given by summation of a smooth, possibly nonconvex function and a convex simple function. The algorithm converts the original problem into a sequence of convex subproblems. Formulating those subproblems requires the evaluation of at most one gradient-value of the original objective and constraint functions. Either exact or approximate subproblems solutions can be computed efficiently in many cases. An important feature of the algorithm is the constraint level parameter. By carefully increasing this level for each subproblem, we provide a simple solution to overcome the challenge of bounding the Lagrangian multipliers and show that the algorithm follows a strictly feasible solution path till convergence to the stationary point. We develop a simple, proximal gradient descent type analysis, showing that the complexity bound of this new algorithm is comparable to gradient descent for the unconstrained setting which is new in the literature. Exploiting this new design and analysis technique, we extend our algorithms to some more challenging constrained optimization problems where (1) the objective is a stochastic or finite-sum function, and (2) structured nonsmooth functions replace smooth components of both objective and constraint functions. Complexity results for these problems also seem to be new in the literature. Finally, our method can also be applied to convex function constrained problems where we show complexities similar to the proximal gradient method.
Polyhedral properties of RLT relaxations of nonconvex quadratic programs and their implications on exact relaxations
Authors: Qiu Yuzhou , Yıldırım E. Alper 
Published: March 2024

Abstract
We study linear programming relaxations of nonconvex quadratic programs given by the reformulation–linearization technique (RLT), referred to as RLT relaxations. We investigate the relations between the polyhedral properties of the feasible regions of a quadratic program and its RLT relaxation. We establish various connections between recession directions, boundedness, and vertices of the two feasible regions. Using these properties, we present a complete description of the set of instances that admit an exact RLT relaxation. We then give a thorough discussion of how our results can be converted into simple algorithmic procedures to construct instances of quadratic programs with exact, inexact, or unbounded RLT relaxations.
