Estimación de biomasa aérea de eucalipto (Eucalyptus grandis) y pino (Pinus spp) en plantaciones forestales comerciales, usando imágenes satelitales Sentinel

La estimacion de la biomasa aerea forestal es necesaria para diversas aplicaciones tecnicas y cientificas, lo que permite mejorar el manejo de los bosques y plantaciones . Dado que las mediciones locales son costosas, existe un gran interes en obtener estimaciones confiables sobre grandes areas a partir de datos de sensores remotos. Actualmente, dichas estimaciones se obtienen con una variedad de fuentes de datos, metodos estadisticos y estandares de prediccion. Los datos de percepcion remota en combinacion con algoritmos de aprendizaje automatico basados en arboles de decision han generado resultados favorables en la estimacion de valores de biomasa aerea (AGB, siglas en ingles). En este estudio, la biomasa aerea se estimo para dos especies de arboles principales, Eucalyptus grandis (E. grandis) y Pinus spp (P. spp), de plantaciones forestales comerciales en el departamento del Cauca, Colombia. La biomasa aerea se estimo combinando los datos SAR (Radar de apertura sintetica) de banda C del satelite Sentinel-1A, las imagenes de textura generadas a partir de los datos de Sentinel-1A, los indices de vegetacion producidos con los datos de Sentinel-2A y datos de inventarios forestales. Se usaron regresiones parametrica lineales y regresiones no parametricas con Random Forest para establecer una relacion entre los valores medidos en campo y los parametros de percepcion remota. El uso de un modelo de Random Forest en combinacion de indices de vegetacion con la retrodispersion de Radar de Apertura Sintetica (SAR, siglas en ingles ) como variables predictoras mostro el mejor resultado para el bosque de E. grandis, con un coeficiente de valor de determinacion de 0,273 y un valor RMSE de 346,62 t.ha-1. En P. spp, el mejor resultado se pudo encontrar en la misma combinacion (R2 = 0,617 y EMC = 9.025 t.ha-1). Este estudio muestra que los datos satelitales Sentinel tienen la capacidad de estimar AGB en plantaciones forestales comerciales y que el algoritmo de aprendizaje automatico Random Forest puede ser muy util para hacerlo.
Generation of fluorescent cell-derived-matrix to study 3D cell migration

Cell migration is involved in key phenomena in biology, ranging from development to cancer. Fibroblasts move between organs in 3D polymeric networks. So far, motile cells were mainly tracked in vitro on Petri dishes or on coverslips, i.e. 2D flat surfaces, which made the extrapolation to 3D physiological environments difficult. We therefore prepared 3D Cell Derived Matrix (CDM) with specific characteristics with the goal of extracting the main readouts required to measure and characterise cell motion: cell specific matrix deformation through the tracking of fluorescent fibronectin within CDM, focal contacts as the cell anchor and acto-myosin cytoskeleton which applies cellular forces. We report our method for generating this assay of physiological-like gel with relevant readouts together with its potential impact in explaining cell motility in vivo.
Probiotics from the standpoint of evidence-based medicine

The number of trials and reports devoted to probiotics is steadily increased. Effectiveness of various probiotic strains of microorganisms is reported for metabolic disorders (diabetes, dyslipidemia, obesity), gastrointestinal diseases (inflammatory bowel disease, constipation, antibiotic-associated diarrhea, Clostridium difficile-associated disease, irritable bowel syndrome), atopic diseases (food allergy, rhinitis), liver diseases (cirrhosis, non-alcoholic fatty liver disease, hepatic encephalopathy), pancreatic diseases (acute pancreatitis) and others. Administration of probiotics in clinical practice is associated with some difficulties due to a huge variety of probiotic drugs, the absence of uniform standards for their production, insufficient evidence base regarding the most effective dosages, forms of release, etc. However, specific strains of probiotics effective for each disease are currently determined with various degrees of evidence. There are recommendations regarding a differentiated approach to the selection of probiotics depending on a
Feasibility and Acceptability of a Mobile Mindfulness Meditation Intervention Among Women: Intervention Study

Background Traditional mindfulness-based stress reduction programs are resource intensive for providers and time- and cost-intensive for participants, but the use of mobile technologies may be particularly convenient and cost-effective for populations that are busy, less affluent, or geographically distant from skilled providers. Women in southern Louisiana live in a vulnerable, disaster-prone region and are highly stressed, making a mobile program particularly suited to this population. Objective This study aimed to (1) assess the feasibility and acceptability of a mobile mindfulness app in real-world conditions in a pilot study of a community sample of women residing in southern Louisiana, (2) describe predictors of app usage, and (3) assess the effect of the app on secondary health outcomes. Methods Women were recruited from an oil spill study on health. A total of 236 women completed a baseline survey, were offered the mobile mindfulness program, and completed a follow-up survey. Subjects were asked to download and use the app for at least 30 days for 10 min. All study procedures were completed on the web. Primary outcomes were feasibility and acceptability of the app and characteristics of app utilization. Secondary outcomes included mindfulness, depression, perceived stress, sleep quality, physical activity, BMI, and healthy eating. Results Overall, 74.2% (236/318) of subjects completed the follow-up survey, and 13.5% (43/318) used the app. The main barrier to app usage was lack of time, cited by 37% (16/43) of users and 48.7% (94/193) of nonusers of the app. Women who chose to use the app were more highly educated (16/43, 63% had a college education vs 65/193, 33.7% of nonparticipants; P<.001), had higher incomes (23/43, 58% had incomes >US $50,000 per year vs 77/193, 43.0% of nonparticipants), and were employed (34/43, 79% vs 122/193, 63.2% of nonparticipants; P=.047). Those who engaged with the app did so at high levels, with 72% (31/43) of participants self-reporting the completion of some or all sessions and 74% (32/43) reporting high levels of satisfaction with the app. Participation with the app had a beneficial impact on depression (odds ratio [OR] 0.3, 95% CI 0.11-0.81), sleep quality (OR 0.1, 95% CI 0.02-0.96), sleep duration (OR 0.3, 95% CI 0.07-0.86), sleep latency (OR 0.3, 95% CI 0.11-0.81), and physical activity (2.8 95% CI 1.0-7.8), but mindfulness scores did not change from baseline to follow-up. Conclusions The Headspace mobile mindfulness app was easy and cost-effective to implement and acceptable to those who participated, but few women elected to try it. The unique characteristics of this southern Louisiana population suggest that more intense promotion of the benefits of mindfulness training is needed, perhaps in conjunction with some therapist or researcher support. Several short-term benefits of the app were identified, particularly for depression and sleep.
No Evidence of Increased Risk of Breast Cancer in Women With Lynch Syndrome Identified by Multigene Panel Testing.

PURPOSE Prior estimates of breast cancer risk in women with Lynch syndrome (LS) range from population risk to 18-fold increased risk with reported differences by gene. Here, breast cancer rates were determined in a large cohort of women with pathogenic variants (PVs) in a mismatch repair (MMR) gene detected through multigene panel testing and compared with rates in the US population and women undergoing panel testing. METHODS MMR gene PV carriers were identified among women tested for suspicion of LS or hereditary breast and ovarian cancer (HBOC) who met inclusion criteria. Standardized incidence ratios (SIRs) and 95% CIs of breast cancer were calculated compared with age-matched incidence in the general US female population and with women negative for PVs stratified by the test indication. RESULTS In total, 0.8% of women (30,362 of 441,966 women) carried MMR gene PVs. PVs in PMS2 (37.5%) and MSH6 (29.3%) were more common than in MLH1 (13.7%) and MSH2/EPCAM (19.4%). Women with PVs in PMS2 and MSH6 were tested more frequently for HBOC, whereas those with PVs in MLH1 and MSH2/EPCAM were tested more frequently for LS. Breast cancer rates in women with LS were lower than those in the general female population (SIR, 0.88; 95% CI, 0.81 to 0.96) and did not differ compared with women with negative panel testing for HBOC (SIR, 0.90; 95% CI, 0.82 to 0.99) or LS (SIR, 1.02; 95% CI, 0.78 to 1.30). CONCLUSION In this large cohort of women with LS identified through panel testing, there was no evidence for increased risk of breast cancer compared with the general US population or women undergoing panel testing. These findings support average-risk breast cancer screening in women with LS.

Textile‐Based Inductive Soft Strain Sensors for Fast Frequency Movement and Their Application in Wearable Devices Measuring Multiaxial Hip Joint Angles during Running

Wearable multiaxes motion tracking with inductive sensors and machine learning is presented. The production, characterization, and use of a modular and size‐adjustable inductive sensor for kinematic motion tracking are introduced. The sensor is highly stable and able to track high‐frequency (>15 Hz) and high strain rates (>450% s−1). Four sensors are used to fabricate a pair of motion capture shorts. A random forest machine learning algorithm is used to predict the sagittal, transverse, and frontal hip joint angle, using the raw signals from sport shorts during running with a cohort of 12 participants against a gold standard optical motion capture system to an accuracy as high as R2 = 0.98 and root mean squared error of 2° in all three planes. Herein, an alternative strain sensor is provided to those typically used (piezoresistive/capacitive) for soft wearable motion capture devices with distinct advantages that can find applications in smart wearable devices, robotics, or direct integration into textiles.
Effects of Omnidirectional Microphone Placement and Survey Period on Bat Echolocation Call Quality and Detection Probabilities

Many factors, including microphone type, affect the quality of acoustic calls recorded by bat detectors and detection probabilities of individual species. Because omnidirectional microphones tend to have a shorter range and record more noise than directional microphones, it has been suggested that these microphones be set farther from reflecting surfaces. Our objective was to determine the effects of microphone height (1.5, 5, and 9 m), distance from forest edge (1, 3, and 5 m), and survey timing on the number of bat files recorded, quality of recorded files, the proportion of identifiable files, and the probability of detecting individual species. We deployed 3×3 arrays of two types of bat detectors with omnidirectional microphones at two sites in Kentucky during two survey periods. We found little evidence for effects of microphone height or distance from forest edge on call quality or detection probabilities of any species. In contrast, survey period significantly affected the number of files recorded, the proportion of high-quality files, the proportion of identifiable files, and the probability of detecting individual species; the length of the recording session also significantly affected the probability of detecting some species. Thus, it appears that biologists have some latitude when placing detectors with omnidirectional microphones on the landscape but timing of surveys should be considered when designing and analyzing bat acoustic survey and monitoring studies.
Concurrent Dynamic Quotient Filters: Packing Fingerprints into Atomics

Quotient filters are approximate membership data structures that can be used for a variety of applications, from speeding up database accesses to uses in computational biology. We look at several improvements to common quotient filters which are orthogonal to each other and can be combined as needed. We show how to use compact arbitrary length data types to reduce the memory usage by up to seven times and get very close to the theoretical optimum. We also present two different approaches to building concurrent quotient filters that use localized locking or no locking at all. This leads to a good speedup with increasing thread counts and an increase in performance of up to four times compared to traditional locking techniques. Using the compact packing technique with concurrent quotient filters also has the benefit of reducing atomic operations and enabling lock elision optimizations. Additionally, we describe how to use a multilevel quotient filter structure to implement dynamic growing while still allowing a user defined maximum false positive rate and being less than 10% slower compared to non-growing variants in scenarios where growing is not necessary.
Professional Competence Is a Condition Precedent to Effective Management-An Argument for Practice Leaders in Legal Service Organizations

There is an unstated argument with an unsettling currency in today’s organizations: Those that can’t do, lead. The concept of management has devolved from a position that facilitates productivity and navigates workplace challenges, to a type of “bullshit job. ” To adherents of this philosophy, competence in one’s vocation, profession or business is unnecessary in order to excel as a manager in that vocation, profession or business. In professional environments technical competence in one’s occupation is a condition precedent to good management. Technically competent managers come to positions of leadership with occupational gravitas. Occupational gravitas is forged from experience and imbues those who possess it with the confidence to effectively navigate the challenges confronting their organization. It is earned from experience dealing with the particular challenges of one’s occupation. Leadership skills are an adjunct to the occupational competence necessary for good management in professional environments. The concept that leadership skills are separate and apart from occupational competence, rather than ancillary to it, in the execution of good management is herein explicitly rejected. People placed in positions of authority who lack experience, or are otherwise incompetent, bring with them not gravitas, but fear. Fear is the primary element from which springs management failures, and through which such failures are expressed. Incompetent leadership is not only dangerous to legal service provider organizations and their employees, but also exposes clients to dire consequences. In a legal services environment, bad management really is a public protection issue. The model of a “practice leader,” is the paradigm through which legal service organizations can model their management style. A practice leader is both an accomplished attorney as well as a leader. Practice leaders understand the work and the environment in which it is produced. This is important because it is they and the organization that are ultimately responsible for the work of their subordinates. Failure of leadership in a legal service environment can not only lead to litigation but could also lead to professional discipline when subordinates engage in misconduct.

Evaluation of serum zinc level as a risk factor for gastrointestinal cancers

Introduction: Gastric adenocarcinoma and esophageal squamous cell carcinoma (ESCC) are the second and third common cancer in Iran respectively and are the leading causes of cancer deaths in the world. The status of serum zinc level in these cancers has not been fully evaluated. Objectives: The aim of the study was to compare serum zinc levels in patients with ESCC and gastric adenocarcinoma as compared to patients with other non-digestive cancers. Patients and Methods: This cross-sectional study was conducted on 100 consecutive patients (10 patients with SCC of the esophagus, 40 patients with gastric adenocarcinoma and 50 cases with other non-digestive cancers as the controls). Morning blood samples were taken containing 5 ml of blood from both groups and immediately stored in the laboratory at 8°C until all samples were taken. After collecting, serum levels of zinc in the specimens were measured by 24i chemistry analyzer. The SPSS version 23.0 for Windows was used for the statistical analysis. Results: The results of this study did not show a significant difference between mean serum level of zinc across the patients with ESCC and patients with gastric adenocarcinoma or those with other non- digestive cancers adjusted for age and gender (P > 0.05). However, a significant difference between the mean serum zinc level in patients with gastric adenocarcinoma and other non-digestive cancers was detected (P < 0.05). Conclusion: Regarding the normal serum level of zinc in other non-digestive cancers and a decrease in zinc level in gastrointestinal cancers in our study, malnutrition which is common in all malignancies, has no effect on zinc deficiency in gastrointestinal malignancies, and zinc deficiency can be considered as a primary risk factor for the development of these two digestive malignancies. Key point Regarding the normal serum level of zinc in other non-digestive cancers and a decrease in zinc level in gastrointestinal cancers in our study, malnutrition which is common in all malignancies, has no effect on zinc deficiency in gastrointestinal malignancies, and zinc deficiency can be considered as a primary risk factor for the development of these two digestive malignancies.

The New Activation Function for Complex Valued Neural Networks: Complex Swish Function

– Complex-valued artificial neural network (CVANN) has been developed to process data with complex numbers directly. Weights, threshold, inputs and outputs are all complex numbers in the CVANN. The convergence of the CVANN back propagation algorithm depends on some factors such as selection of appropriate activation function, threshold values, initial weights and normalization of data. The most important of these factors is the selection of the appropriate activation function . The selection of activation function determines the convergence and general formation characteristics of the complex back propagation algorithm. In this study, the swish activation function discovered by Google researchers Prajit Ramachandra, Barret Zoph and Quoc V. Le is discussed in the complex domain. Swish activation function, which gives good results in real plane, has been studied in the complex plane. We have compared the performance of swish activation functions on the complex XOR and symmetry problems with other known activation functions. The simulations’ results show that the proposed network using swish activation function, gives the best results when compared to other networks using the traditional complex logarithmic sigmoid and tangent sigmoid activation functions.
