La madera, muy presente en estructuras de edificios patrimoniales, es un material de gran vulnerabilidad ante escenarios adversos (humedad y xilófagos, fundamentalmente). Durante la inspección de las estructuras de madera para decidir si es necesario realizar una intervención y conservación de esta, se debe diagnosticar su estado atendiendo a distintos parámetros, respetando la legitimidad del monumento de ser conservado. Este trabajo presenta una metodología de inspección no destructiva basada en métodos acústicos con el objetivo de tomar decisiones inteligentes de intervención. En concreto, se estudia la detección de xilófagos activos en la madera mediante la técnica de emisión acústica y la determinación de las características resistentes de las vigas mediante inspección por ondas elásticas para la obtención del módulo elástico y asignación de una clase resistente según la norma UNE-EN 338:2016. Además, se presentan ejemplos de aplicación en edificios patrimoniales incluyendo la clasificación visual para detección de patologías y la asignación de clases resistentes según la norma UNE-EN-56544, y el análisis estructural mediante modelado numérico.AbstractWood, which is very present in the structures of heritage buildings, is a material that is highly vulnerable to adverse scenarios (mainly damp and xylophages). During the inspection of wooden structures to decide whether an intervention and conservation of the structure is necessary, its condition must be diagnosed according to different parameters, respecting the legitimacy of the monument to be conserved. This work presents a non-destructive inspection methodology based on acoustic methods with the aim of making intelligent intervention decisions. Specifically, it studies the detection of active xylophages in wood using the acoustic emission technique and the determination of the strength characteristics of beams by means of elastic wave inspection to obtain the elastic modulus and assign a strength class according to the UNE-EN-338:2016 standard. In addition, examples of application in heritage buildings are presented, including visual classification for the detection of pathologies and the assignment of strength classes according to UNE-EN-56544, and structural analysis by means of numerical modelling.

Published: March 2023

Tungiasis has been included in the WHO list of Neglected Tropical Diseases, but systematic data on the occurrence are scarce. We analyzed data on the occurrence of tungiasis in the 184 munici-palities of Ceará State in Northeast Brazil, based on an online open rapid assessment question-naire focused on health professionals and other key stakeholders. Questions included the occur-rence of tungiasis, severe cases, cases in animals and seasonal variations of the disease. There were in total 1,265 individual data entries available (1 to 104 per municipality) from all munici-palities of the state. A total of 181 (98.3%) of municipalities reported the occurrence of tungiasis in the past or currently, 120 (65.2%) reported current occurrence, 155 (84.2%) severe cases in the past or currently; and 47 (25.5%) reported severe cases currently. A total of 132 (71.7%) municipalities reported tungiasis in animals, most commonly in dogs (97), pigs (80), cats (50), horses (20), cattle (8) and goats (6). Most municipalities mentioned the seasonality of tungiasis (n=146; 79.3%). There was no report of any specific tungiasis control program. Our data show that tungiasis and severe tungiasis commonly occur in Ceará state and that tungiasis is a significant public health issue for both humans and animals. An integrated One Health approach is needed to reduce dis-ease burden, including human and animal health, and the environment.

Published: March 2023

Cluster of differentiation 44 (CD44) is a type I transmembrane glycoprotein, and has been shown as a cell surface marker of cancer stem-like cells in various cancers. Especially, the splicing variants of CD44 (CD44v) are overexpressed in cancers, and play critical roles in cancer stemness, invasiveness, and resistance to chemotherapy and radiotherapy. Therefore, the understanding of the function of each CD44v is indispensable for the CD44-targeting therapy. CD44v9 contains the variant 9-encoded region, and its expression predicts poor prognosis in patients with various cancers. CD44v9 plays critical roles in the malignant progression of tumors. Therefore, CD44v9 is a promising target for cancer diagnosis and therapy. Here, we developed sensitive and specific monoclonal antibodies (mAbs) against CD44 by immunizing mice with CD44v3–10-overexpressed Chinese hamster ovary CHO-K1 (CHO/CD44v3–10) cells. We first determined their critical epitopes using enzyme-linked immunosorbent assay, and characterize their applications to flow cytometry, western blotting, and immunohistochemistry. One of the established clones, C44Mab-1 (IgG1, kappa) reacted with a peptide of the variant 9-encoded region, indicating that C44Mab-1 recognizes CD44v9. C44Mab-1 reacted with CHO/CD44v3–10 cells or colorectal cancer cell lines (COLO201 and COLO205) by flow cytometry. The apparent dissociation constant (KD) of C44Mab-1 for CHO/CD44v3–10, COLO201, and COLO205 was 2.5 × 10−8 M, 3.3 × 10−8 M, and 6.5 × 10−8 M, respectively. Furthermore, C44Mab-1 was able to detect the CD44v3–10 in western blotting, and endogenous CD44v9 in immunohistochemistry using colorectal cancer tissues. These results indicated that C44Mab-1 is useful for detecting CD44v9 not only in flow cytometry or western blotting but also in immunohistochemistry against colorectal cancers.

Maximal heart rate (HRmax) is a widely used measure of cardiorespiratory fitness. Prediction of HRmax is an alternative to cardiopulmonary exercise testing (CPET), but its accuracy among endurance athletes (EA) requires evaluation. This study aimed to externally validate HRmax prediction models in the EA independently for running and cycling CPET. 4043 runners (age=33.58 (8.12) years; 83.53% males; BMI=23.66 (2.54) kg·m−2) and 1026 cyclists (age=36.88 (9.03) years; 89.67% males; BMI=24.04 (2.65) kg·m−2) underwent maximum CPET. Student t-test, mean absolute percentage error (MAPE), mean absolute error (MAE), and root mean square error (RMSE) were applied to externally validate 8 running and 5 cycling HRmax equations. HRmax was 184.60 (9.79) beats·min−1 and 182.66 (10.28) beats·min−1 respectively for running and cycling, p=0.001. Measured and predicted HRmax differed significantly (p=0.001) for 9 of 13 (69.23%) models. HRmax was overestimated by 8 (61.54%) and underestimated by 5 (38.46%) formulae. Overestimated HRmax ranged 0.08-4.94 beats·min−1 and underestimated HRmax ranged 0.03-4.90 beats·min−1. MAE and RMSE were 0.18-4.94 beats·min−1 and 9.13-10.47, respectively. MAPE ranged 3.95-4.69%. Prediction models do not allow for accurate estimation of HRmax. HRmax was more often underestimated than overestimated. Predicted HRmax can be implemented for EA as a supplemental method but CPET is the preferable approach.
YCl3-substituted CsPbI3 Perovskite Nanorods for Efficient Red Light-emitting Diodes

Published: March 2023

Cesium lead iodide (CsPbI3) perovskite nanocrystals (NCs) are a promising material for red light-emitting diodes (LEDs) due to their excellent color-purity and high luminous efficiency. However, small-sized CsPbI3 colloidal NCs, such as nanocubes, used in LEDs suffer from confinement effects, negatively impacting their photoluminescence quantum yield (PLQY) and overall efficiency. Here, we introduced YCl3 into the CsPbI3 perovskite, which formed anisotropic, one-dimensional (1D) nanorods. This was achieved by taking advantage of the difference in bond energies between Cl− and I− ions, which caused YCl3 to promote the anisotropic growth of CsPbI3 NCs. The YCl3-based nanorods improved the PLQY and storage stability by passivating the defects reducing the nonradiative recombination rates. When the YCl3-substituted CsPbI3 nanorods are applied to the emissive layer in LEDs, we achieve an external quantum efficiency of ~3.16% which is 1.86-fold higher than the pristine CsPbI3 NCs (1.69%) based LED. Notably, the ratio of horizontal transition dipole moments (TDMs) in the anisotropic YCl3:CsPbI3 nanorods was determined to be 75%, which is higher than the isotropically oriented TDMs in CsPbI3 nanocrystals (67%). This increased TDM ratio led to higher light outcoupling efficiency in nanorods-based LEDs. Overall, the results suggest that YCl3-substituted CsPbI3 nanorods could be promising for achieving high-performance perovskite LEDs.
Investigation of Rock Joint and Fracture Influence on Delayed Blasting Performance

Published: March 2023

Geological structures such as joints and faults in rock mass have significant influence on open pit mining. Hence, it is critical to develop a understanding of dynamic joint behaviour under blasting loading. This in turn can provide both theoretical and practical guidance to improve blasting rock fragmentation and associated bucket excavating efficiency. In this paper, delayed blasting on the highwall bench at Baiyunebo open-pit mine was used as an example, a nonlinear joint blasting model was also constructed. By simplifying the blasting wave propagation velocity, the P-wave normal incidence to the joint was obtained. The peak vibration velocity was 0.33m/s at 3.0s. The S-wave reflected by the joint interface was first reflected backward and then forward, which the peak vibration velocity was 0.027 m/s. By combining the relevant stress and displacement theories of type I and II cracks, the equipotential diagrams of the stress and displacement field with the vibration velocity of the particle were obtained. σx was positive in the direction of 0~330° and subjected to tensile stress, whereas σy was positive in the direction of 0~180° and under tensile stress. The longitudinal σy along joint was low in compressive stress distribution area and did not affect surrounding rock at the time. The stress concentration appeared in the lower right corner. Based on the continuous behavior of stress wave in joints, the asymmetry and continuous changes reflected in the whole process could not be analysed by the contour diagram. Hence, ANSYS used to analyse distribution of the stress field. The intensity of the shock wave after detonation was greater than that of the rock strength. Subsequently, the sub-layer shock wave supplemented the shock wave energy that was not enough to break the rock and induced further cracking. This was able to be visualized by the degree of color change post-processing. It was concluded that with the attenuation of the detonation wave energy, the stress exhibited a decreasing trend in this process. According to distribution of the peak effective stress, it was found that the peak value first increased to 10-12 MPa and then showed a downward trend. Overall, the results were validated against the finite element simulation and mathematical analysis.

Measles is a highly contagious airborne disease that is endemic in many developing countries with low levels of vaccination coverage. In this paper, we propose a deterministic compartmental mathematical model for measles disease dynamics. We establish the global stability conditions for the disease-free and endemic equilibria using the Lyapunov function stability method. \textcolor{red}{Using arbitrary parameters it is obtained that the proposed model exhibits forward bifurcation}. Numerical integration using MATLAB software was used to simulate the model solution of the forward problem. We calibrate the proposed model to estimate the parameters with a 95\% confidence interval (CI) using real data from Ethiopia by formulating an inverse problem. We notice that the model fits well with the real data of Ethiopia. The estimated basic reproduction number ($R_0$) is found to be $R_0=1.3973$ which proves that the disease is endemic. It is also obtained from the local sensitivity analysis that reducing the transmission rate and increasing the vaccination rate could effectively minimize the $R_0$.

Background: Redo mitral valve surgery is the standard of care for failed mitral bioprostheses or recurrence of mitral regurgitation after repair. Nonetheless, catheterbased valve-in-valve (ViV) or valve-in-ring (ViR)-procedures increasingly become viable alternatives in high risk subpopula-tions. Despite reported good initial results, only little is known about longer-term outcomes. The present series report long-term outcomes of transcatheter mitral ViV- and ViR-procedures. Methods: All consecutive patients (n=54) undergoing transcatheter mitral ViV- or ViR-procedures for failed bioprostheses or recurring regurgitation after mitral repair were retrospectively en-rolled in the time period between 2011 and 2021. The mean age was 76.5 ± 6.5 years, and 30 (55.6%) of the patients were male. The procedures were done using a commercially available balloon-expandable transcatheter heart valve. Clinical and echocardiographic follow-up data were obtained out of the hospital’s database and analyzed. Follow-up reached up to 9.9 years with a total of 164.3 patient-years. Results: A total 25 patients received a ViV- and 29 patients a ViR-procedure. Both groups were at high surgical risk with an STS-PROM of 5.9 ± 3.7 % in ViV- and 8.7 ± 9.0% in ViR-patients, respectively (p<0.01). The procedures itself were mainly unevent-ful with no intraoperative deaths and a low conversion rate (n=2/54; 3.7%). VARC-2 procedural success was low (ViV 20.0% and ViR 10.3%; p=0.45), which was either driven by high rates of transvalvular pressure gradients “>5mmHg” (ViV 92.0% and ViR 27.6%; p<0.01) or residual regurgitation “>trace” (ViV 28.0% and ViR 82.7%; p<0.01). ICU-stay was prolonged in both groups (ViV 3.8 ± 6.8 days and ViR 4.3 ± 6.3 days; p=0.96) with acceptable hospital stay (ViV 9.9 ± 5.9 days and ViR 13.5 ± 8.0 days; p=0.13). Despite 30-days mortality was acceptable (ViV 4.0% and ViR 6.9%; p=1.00), the mean posthospital survival time was disappointingly low (ViV 3.9 ± 2.6 years and ViR 2.3 ± 2.7 years; p<0.01). Overall survival I the entire group was 33.3%.Cardiac reasons for death were frequent in both groups (ViV 38.5% and ViR 52.2%). Cox-regression analysis identified ViR-procedures as a predictor of mortality (HR 2.36, CI 1.19 - 4.67, p=0.01). Conclusions: Despite acceptable immediate outcomes in this high-risk subpopulation, long-terms results are discouraging. Transvalvular pressure gradients as well as residual regurgitations remained drawbacks in this real-world population. The indication for catheterbased mitral ViV- or ViR-procedures thoughtfully must be made in consideration of conventional redo-surgery or conservative treatment.

Published: March 2023

This study analyzed the impact of missing data techniques on performances of two differential item functioning (DIF) detection methods (Mantel Haenszel and Multiple Indicator and Multiple Causes) under missing completely at random missing data mechanism. Percentage of missing data was set at 5% and 15%. Zero imputation, listwise deletion and fractional hot-deck imputation were used to handle missing data. The data set of the study consisted of 17 items in the S12 item cluster of Programme for International Student Assessment (PISA) 2015 science test. Results showed that fractional hot-deck imputation produced the best results in identifying DIF items in all conditions and it had also the closest DIF values to the values obtained from complete data set. It was also found that multiple indicator and multiple causes method was more adversely affected than Mantel Haenszel by the presence of missing data.

Authors:   , Menacho Mendoza Elizabeth Rosario
Published: March 2023

La seguridad de un sistema de implantes dentales radica principalmente en la capacidad de cargas; mientras que su conexión interna en la modificación de estas. Por lo tanto, su trabajo en conjunto nos permitirá una mayor estabilidad y hará que el sistema obtenga una mejor distribución de la tensión y un mayor factor de seguridad mientras que, su conexión interna otorgará una retención al pilar, sin exponer al tornillo a un riesgo de un futuro aflojamiento o rotura. Por ello, el propósito del estudio fue determinar las tensiones máximas, factor de seguridad y deformación de tres sistemas de implantes dentales (pilar, tornillo del pilar e implante dental) mediante el método de los elementos finitos. Se diseñaron tres sistemas de implantes dentales en base a tres marcas comerciales Sweden&Martina, Dentium y Straumann, mediante el método de elementos finitos usando el programa SolidWorks® 2020, a cada uno de los diseños se les aplico una fuerza de 200 N y 800 N, en dos direcciones axial y tangencial de 30°. Además, se diseñó un bloque de hueso con estructuras biológicas. Al comparar los tres sistemas de implantes dentales con diferentes conexiones internas, se concluyó que el máximo estrés de Von Mises se concentró a nivel cervical de los tres modelos, donde el modelo C mostró los mejores resultados, tanto en las fuerzas de 200 N y 800 N. Asimismo, las mayores tensiones se observaron en la aplicación de la carga tangencial en todos los modelos de estudio. Relevancia clínica: Un trabajo en conjunto entre los componentes del sistema del implante, como el modelo B y C, otorgan un mejor manejo de la distribución de estrés, asimismo la presencia de una plataforma switching.

Esta investigación determinó el potencial de toxicidad de los lixiviados de la mezcla de colillas de cigarro, de las marcas con mayor participación en el mercado peruano, en Daphnia magna (Straus 1820) y Artemia franciscana (Kellog 1906). Se realizaron ensayos de toxicidad considerando las recomendaciones estandarizadas para D. magna y para la A. franciscana. Se utilizó el software TRAP (Toxicity Relationship Analysis Program) para determinar la CL50 (concentración letal media) considerando límites de confianza del 95% y el programa Past 3.2 para determinar la menor concentración que produce efectos observables, (LOEC) y la mayor concentración en la cual no se ve efecto, NOEC. Los resultados mostraron una CL50 de 1.29 ± 0.09 colillas/L (449.7 ± 31.9 mg/L) para la D. magna y de 4.27 ± 0.53 colillas/L (1482.54 ± 185.28 mg/L) para la A. franciscana. Los parámetros NOEC y LOEC para la D. magna fueron de 0.84 colillas/L (293.16 mg/L) y 1.12 colillas/L (389.14 mg/L), respectivamente, y los mismos parámetros para la A. franciscana fueron de 2 colillas/L (694.9 mg/L) y 4 colillas/L (1389.8 mg/L), respectivamente. Se estableció la concentración sobre la cual se esperan efectos adversos por parte de las colillas de cigarro (PNEC), cuyo valor para la D. magna y la A. franciscana fue de 0.001 colillas/L y 0.004 colillas/L, respectivamente. En Perú, se propone que, en agua dulce, las colillas de cigarro no deben sobre pasar los 1.29 x 10-3 colillas/L (0.45 x mg/L) , y en agua de mar las colillas de cigarro no deben sobre pasar los 4.27 x 10-3 colillas/L (1.48 x mg/L); ya que podría generar daños al ecosistema.

Published: March 2023

Accurate simulation of the thermoporoelasticity problems is beneficial for the exploitation activities of aquifers, geothermal, and hydrocarbon reservoirs. Simulating such problems using a finite-element Continuous Galerkin scheme (CG) lacks local energy/mass conservation. Despite being a conservative scheme, Discontinuous Galerkin (DG) is computationally expensive with much higher degrees of freedom (DoFs). This paper presents the Enriched Galerkin scheme (EG) implementation for thermoporoelasticity problems to ensure local energy/mass conservation with fewer DoFs.

Here, we deal with the notion of information validity and relevance, and data source reliability as applied to the design, development and information updating in contemporary OLAP systems. Many up-to-date information systems employ a great many external data sources but the reliability of these sources and data validity therein raise doubts. In addition, the data is continually changed and updated from the old to the latest, which needs to be borne in mind. The problem is that there is no unified system for qualitative and quantitative assessment of information attributes such as degrees of relevance and validity, and data source reliability. On the other hand, there is an array of information attributes that can be the judge of relevance and validity. The present study aimed to elaborate approaches to assessing information relevance and validity, and data source reliability for an OLAP database system and propose units of measure, algorithms and computational methods for the same. The elaborated approaches will further be actualized as algorithms and programs as part of the OLAP database system under development.

Published: March 2023

The failure of components can lead the whole system to fail, replacing an important component with another one of the same type can help the system to rework at lower cost. In this paper, a component swapping method is presented based on the components importance analysis. First, an appropriate manufacturing process is selected before calculating system reliability. Based on the current manufacturing requirements and processing strategy, the reliability block diagram of manufacturing process is constructed for the structure analysis. Then the system reliability is calculated after completing the structure analysis by the application of survival signature. Finally, system reliability is improved by the proposed component swapping method. The effectiveness and feasibility of the proposed approaches are demonstrated with two examples of manufacturing system.
Mechanism of Low Frequency Vibration Caused by Actuator Saturation for AMB based Motor and Its Compensation Strategy
Authors: JI LI , Chen Ke-ping , Ma Xue-qing
Published: March 2023

A nonsynchronous low frequency vibration occurs in high-speed motor system with active magnetic bearing (AMB) was studied. The mechanism was analyzed from three aspects of actuator saturation, eddy current effects and external noises. The results show that the gain decrease caused by the actuator saturation is the main reason to induce the low frequency vibration, and the nonlinearity of electromagnetic force and switching power amplifier will further exacerbate the performance. The eddy current effects and external noises did not directly contribute to the low frequency vibration, but they will make the actuator more prone to saturation, so as to involve this matter. Then, the stability of AMB system with saturation nonlinearity was analyzed according to the extended Nyquist stability criterion method, and the compensation strategy based on the synchronous rotating frame (SRF) was present. For verification, a prototype of 100kW AMB-based PMSM and its system were developed and the experiments regarding to vibration response were carried out. The experimental results showed that the proposed compensation strategy could effectively filter out the synchronous component of the control current, so as to prevent the actuator saturation. In addition, during the rated speed of 30000r/m, the maximum rotor vibration amplitude with the compensator was reduced by about 21% compared with alone PID controller.

Background
Arthritis is a common chronic disease, leading to poor quality of life, which has received increasing attention. This study aimed to examine the associations of arthritis with functional disability and depressive symptom among the general US adults.
Methods
Participants were from the National Health and Nutrition Examination Survey (NHANES) 1988–1994 and 1999–2018. Arthritis was self-reported or graded by the Kellgren-Lawrence score after an objective X-ray examination. Functional disability included disability in activities of daily living (ADL disability), instrumental activities of daily living (IADL disability) and mobility disability. Depressive symptom was assessed using the Patient Health Questionnaire (PHQ). Multivariable logistic regression models were used to examine the associations.
Results
We included 22,566 older adults (≥ 60 years; 10,961 had self-reported arthritis) for functional disability analysis (2,377 older adults with data on X-ray examination; 1,012 had radiographic knee osteoarthritis) and 32,056 adults (≥ 20 years; 9,175 had self-reported arthritis) for depressive symptom analysis. After controlling for all covariates, self-reported arthritis was associated with ADL disability (odds ratios [OR]: 2.68; 95% confidence interval [CI]: 2.50–2.87), IADL disability (OR: 2.06; 95% CI: 1.94–2.20) and mobility disability (OR: 2.95; 95% CI: 2.78–3.14), and depressive symptom (OR: 2.18; 95% CI: 1.98–2.40). In participants with data on X-ray examination, radiographic knee osteoarthritis was only associated with mobility disability (OR: 1.44; 95% CI: 1.18–1.74).
Conclusions
Arthritis was associated with functional disability and depressive symptom in general US adults. Appropriate managements of physical and mental health are needed for those with arthritis, to improve their quality of life.

Published: March 2023

Background: The increasing global population and prolongation of lifespan has led to frailty becoming an important health problem. Therefore, this study aimed to investigate the effects of having living and deceased children on frailty among older parents.
Methods: A total of 98 patients aged ≥65 years were included in the study. Data on the number of male, female, and deceased children were obtained. All patients were evaluated for frailty using the FRAIL Index (FI) and Tilburg Frailty Indicator (TFI). This study is prospective.
Results: A weak, positive correlation was found between the total number of children and FI in female participants (r: 0.435; P = 0.001; P< 0.01), whereas a weak, positive correlation was noted between the number of female children and FI (r: 0.400; P = 0.001; P < 0.01). No statistically significant correlation was found between the number of male children and FI (P > 0.05). A moderately positive and statistically significant relationship was also found between the number of deceased children and FI (r: 0.517; P = 0.001; P < 0.01). Frailty ratios did not significantly differ based on the number of male, female, and deceased children (P > 0.05). A weak, positive correlation was found between the number of male children and TFI (r: 0.369; P = 0.029; P < 0.05).
Conclusions: We showed that having female children in women and male children in men increases the risk of frailty among older Turkish parents. Additionally, having a deceased child increases the probability of frailty among older mothers. Therefore, the “child” factor should be given importance when evaluating frailty risk in older individuals.

Published: March 2023

Purpose: This study was conducted to examine the effects of physical and psychological symptoms seen in inpatient cancer patients on spiritual well-being and emotional distress.
Method: This descriptive and cross-sectional study was conducted with 98 cancer patients treated in oncology, haematology, and stem cell services at a university hospital between April-June 2022. Socio-Demographic Characteristics Form, Karnofsky Performance Scale, Nightingale Symptom Assessment Scale, Hospital Anxiety and Depression Scale, Distress Thermometer and Spiritual Well-being Scale were used to collect data. Statistical analyzes were made by taking the descriptive features of the data.
Results: It was determined that 55.1% of the patients were diagnosed with cancer for more than one year, 53.1% receiving treatment for more than one year, 61.2% were diagnosed with haematological cancer, and 62.2% were treated only with chemotherapy. Cancer type (p<0.01), treatment (p<0.05) and Karnofsky scores (p<0.01) had an effect on the on spiritual well-being and distress scores. It was determined that 39.8% of the patients were in the yellow zone of the distress thermometer, could not manage their stress well and needed psychological support. As the psychological symptoms of the patients increased, their spiritual well-being declined (r=-0.447, p<0.01), and as their physical (r=0.222, p<0.05) and psychological (r=0.311, p<0.01) symptoms increased, their distress scores increased.
Conclusion: It is anticipated that identifying the problems that patients have and making interventions to solve those problems by oncology nurses would significantly contribute to the patient’s spiritual well-being and emotional distress.

Research and wind speed assessment has increased lately among other things, due to its interest as a renewable energy resource. Whereas mean values and trends are commonly studied, less attentions is paid to the evaluation of extremes. In terms of lower winds, it is difficult to find agreement on a definition for those conditions. Here, the long-term characterization of low wind values over oceanic and land regions in Europe is assessed from hourly data of ERA5 reanalysis for the period 1979-2018. An absolute threshold (cut-in) related to a generalized wind power curve is used. The number of hours below cut-in threshold (3 m/s) present a reasonable agreement with the available observations, with annual values around 3000-4000 h for most of the locations over Europe, although severe limitations are found to properly represent wind speed field over mountainous areas. Important differences in the amount of hours below cut-in threshold are obtained between northern and southern regions of the domain, where the overall more complex orography and coast line seems to play a relevant role. Interannual and seasonal low wind variability show differences larger than 20-25\% for both timescales. Atlantic Ocean and Mediterranean regions behave differently, but both with less low wind values than land regions. In terms of persistence, analysis of low wind spells indicate that the largest ones, on annual averages, can reach up to 120 consecutive hours (4-5 days) over many land areas. Overall, mean hourly wind spells range from 10 to 20 h, with more than 200 episodes per year
