Dataset used in the evaluation of the paper "Heuristic-Based Incremental Local Domain Model Generation", currently under review in "Information and Software Technology". Context: Current front-end frameworks and technologies enable rich clients to operate autonomously without frequent server requests. To achieve this autonomy, clients must maintain a Local Domain Model (LDM), often derived from the Global Domain Model (GDM) on the backend. Manually designing an LDM that is consistent with the GDM requires handling nuanced dependencies, an error-prone task where oversight is easy. Objective: To address these challenges we aim to: (a) formally map dependencies between GDM and LDM; (b) analyze effort and errors when modelling without assistance; and (c) provide a semi-automated method leveraging these dependencies to significantly reduce both effort and errors. Method: To achieve these objectives, we propose a heuristic-based, step-by-step guided method. This approach leverages pre-existing GDM information to incrementally uncover dependencies and automate LDM construction as designers identify local behavior of GDM elements. We assessed this method's impact through an empirical experiment where we aimed to identify common mistakes and quantify effort during LDM construction. Expert UML modelers completed an LDM creation task both manually and with our tool-supported method. We recorded errors and cognitive effort to establish a baseline and measure impact. User perceptions were gathered via a survey; an analytical usability study based on GOMS complemented findings. Results: The proportion of users committing errors decreased by 77.8% with the tool, and the average error count per user was reduced by 97.3%. Time to complete the task decreased by 35.0% and interactive effort by 44.6%, consistent with GOMS predictions. Surveys showed majority positive responses across all items. Conclusions: Our approach effectively streamlines Local Domain Model creation. By automatically detecting dependencies and guiding designers, the tool drastically reduces error rates, cuts completion time, and lowers interaction volume. Expert users rated the method positively, affirming that benefits of guided, incremental LDM construction outweigh adoption effort., This work has been funded by the Government of the Principality of Asturias, with support from the European Regional Development Fund (ERDF) under project IDE/2024/000751 (GRU-GIC-24-070).

La combinación de la fotoquímica con las interacciones de enlace halógeno ha emergido en los últimos años como una herramienta sintética poderosa para la generación de intermedios radicalarios bajo condiciones suaves. En la formación de radicales centrados en carbono, esta reactividad se ha limitado hasta ahora al uso de haluros arílicos y alquílicos como precursores. Ahora planteamos que la formación iniciada por enlace halógeno de radicales vinílicos altamente reactivos sería un proceso viable para el acoplamiento cruzado fotoquímico entre tioles y haluros alquenilos en condiciones básicas. De hecho, la reacción muestra una tolerancia muy amplia a grupos funcionales, es estereoselectiva, sencilla y escalable. Estudios mecanísticos detallados indican la formación de radicales vinílicos y centrados en azufre como los intermedios de la reacción, y cálculos DFT respaldan la preformación de un complejo de enlace halógeno como el iniciador de la transformación fotoquímica. Se desarrollaron aplicaciones sintéticas para ampliar la utilidad de esta metodología., Se agradece sinceramente el apoyo financiero a este trabajo mediante una beca postdoctoral “Margarita Salas Joven” de FICYT (Principado de Asturias) concedida a M.

--------------------------MATLAB DATA DESCRIPTION------------------------ List of variables: 'F_FEM_Unperturbed': Natural frequencies of the unperturbed finite element model. 'F_EXP_Unperturbed': Experimental natural frequencies of the unperturbed structure. 'F_EXP_Perturbed': Experimental natural frequencies of the perturbed structure. 'M_FEM_Unperturbed': Modal matrix (mass-normalized) of the unperturbed finite element model. 'M_EXP_Unperturbed': Experimental modal matrix of the unperturbed structure. 'M_EXP_Perturbed': Experimental modal matrix of the perturbed structure. Notes Frequencies are given in Hz. In the modal matrices, each row corresponds to one measured degree of freedom, and each column corresponds to one mode shape. The dataset includes the first six modes of each model., This dataset contains the modal data corresponding to a symmetric steel cantilever beam with repeated bending modes. The dataset includes modal parameters, namely natural frequencies [Hz] and mode shapes, for the following models: - Experimental unperturbed model. - Numerical unperturbed model, developed in ABAQUS. - The experimental perturbed model. The perturbation was introduced by fully filling the upper 0.6 m part of the structure with sand. The added mass was 1.06 kg, corresponding to approximately 9.22% of the total mass of the system. The experimental modal parameters were obtained through Operational Modal Analysis (OMA). The responses were measured at 12 points and the modal parameters were estimated using the Stochastic Subspace Identification (SSI) method.

Introduction. Hemophilic knee arthropathy leads to a reduction in muscle mass and strength. Blood flow restriction (BFR) involves the application of a compressive cuff that enables strength training with reduced loads. Objective. To evaluate safety as the primary outcome and the efficacy (muscle strength and activation, functional capacity, and quality of life) as secondary outcomes of a quadriceps strengthening programme using blood flow restriction in patients with haemophilia. Methods. A randomized clinical trial was conducted with 33 participants assigned to either an experimental group (strength training with BFR) or a control group. The four-week intervention included three weekly sessions and two strength exercises (leg extension and squat). Outcomes assessed were safety (clinical hemarthrosis), strength (dynamometry), muscle activation (surface electromyography), pain threshold (pressure algometry), range of motion (goniometry), functional capacity (Timed Up and Go), and quality of life (36-Item Short Form Survey). Follow-up assessments were performed four weeks post-intervention to evaluate effect persistence. Results. Thirty participants completed the study. No participants experienced clinical hemarthrosis or hematomas during the intervention, confirming safety as the primary outcome. Additionally, blood flow restriction training produced significant gains in quadriceps strength (p<0.001;η²p=0.19) and activation (p<0.001; η²p=0.28). Further improvements (p<0.05) were observed in pain threshold, knee range of motion, and the physical component of quality of life. Conclusions. Blood flow restriction strength training is safe for patients with hemophilia. It may enhance quadriceps strength and activation, raise pain thresholds, and improve knee mobility. Patients show better physical functioning, less bodily pain, and improved physical quality of life., This work has received financial support from Swedish Orphan Biovitrum S.L.
