Cognitive Ergonomics Evaluation Assisted by an Intelligent Emotion Recognition Technique

The study of the cognitive effects caused by work activities are vital to ensure the well-being of a worker, and this work presents a strategy to analyze these effects while they are carrying out their activities. Our proposal is based on the implementation of pattern recognition techniques to identify emotions in facial expressions and correlate them to a proposed situation awareness model that measures the levels of comfort and mental stability of a worker and proposes corrective actions. We present the experimental results that could not be collected through traditional techniques since we carry out a continuous and uninterrupted assessment of the cognitive situation of a worker.
A National Survey on Mental Health Professional Development in Juvenile Justice Facilities: Implications for Youth Reentry

A national study of clinical directors examined professional development (PD) focused on mental health provided to professionals in juvenile justice facilities for adjudicated youth. A total of 85 clinical directors responded to a mail survey (45% return rate). The survey questions related to (a) topics of staff training and the basis for choosing topics, (b) which professionals participated in each PD topic, (c) training format and frequency of PD, (d) recommended attributes of PD, (e) methods of evaluating PD, and (f) adequacy of PD and how can it be improved. For each topic, PD was typically provided once per year and face to face, rather than online. PD participation rates were commonly in the 30% and 40% ranges for professionals other than clinical directors and counselors, with teachers, correctional officers, administrators, and teaching assistants receiving PD the least. Rarely did PD include recommended attributes of PD, and it was commonly viewed as ineffective. Implications for research and practice related to PD and its relationship to youth reentry from juvenile justice facilities are discussed.
An Enhanced Finite Element method for Two Dimensional Linear Viscoelasticity using Complex Fourier Elements

In this paper, the finite element analysis of two-dimensional linear viscoelastic problems is performed using quadrilateral complex Fourier elements and, the results are compared with those obtained by quadrilateral classic Lagrange elements. Complex Fourier shape functions contain a shape parameter which is a constant unknown parameter adopted to enhance approximation’s accuracy. Since the iso-parametric formulation utilized in the finite element code, based on the experience of authors, it is proposed that a suitable shape parameter for each problem is adopted based on an acceptable approximation of the problem’s geometry by a complex Fourier element. Several numerical examples solved, and the results showed that the finite element solutions using complex Fourier elements have excellent agreement with analytical solutions, even though noticeable fewer elements than classic Lagrange elements are employed. Furthermore, the run-times of the executions of the developed finite element code to obtain accurate results, in the same personal computer, using classic Lagrange and complex Fourier elements compared. Run-times indicate that in the finite element analysis of viscoelastic problems, complex Fourier elements reduce computational cost efficiently in comparison to their classic counterpart.
The critical illness mortality inflection point during prolonged Surgical ICU length of stay

Background: The purpose of this study is to determine the relationship between ICU Length of Stay (LOS) and mortality in a surgical population and evaluate predictors of mortality at a LOS inflection point. Methods: All patients admitted to a surgical ICU from July 2003 through June 2014 at a well-established, urban, academic medical center were retrospectively reviewed via a prospective registry. In-hospital mortality rates were determined and plotted for each ICU LOS day through the first 6 weeks. Identified mortality curve slope change was used to identify an at-risk cohort. Using the most recent one-year data, risk factors including APACHE II were recalculated on the inflection point day to assess metric validity. Results: 19,061 ICU admissions were assessed. Mortality followed a sigmoid curve with a significant rise occurring during week two that plateaued by ICU day 14. Mortality rates based on LOS ≤ 14 days vs. > 14 days significantly differed (4.23% vs. 21.6%, p<0.001). There were 130 patients with a >14-day LOS in the most recent year cohort. Re-calculated APACHE II scores on ICU day 14 were significantly predictive of mortality, 23.64 for deaths (95% CI: 21.36-25.92) vs. 16.35 for survivors (95% CI: 15.50-17.20), p<0.001. Additional independent day 14 mortality predictors included pressor use (44.0% vs. 21.9%, p<0.02), bacteremia (44.0% vs. 16.2%, p<0.002), active malignancy (40.0% vs. 16.2%, p<0.005), and dialysis (36.0% vs. 10.5%, p<0.001). Conclusions: Mortality significantly increases after 14 days in a surgical ICU. Recalculation of APACHE II score at this inflection point is valid and correlative of mortality. This methodology can be helpful for informing decision making for patients who require ICU care exceeding 14 days duration.

Peer review of the pesticide risk assessment of the active substance kieselgur (diatomaceous earth)

Abstract The conclusions of EFSA following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State Austria and co‐rapporteur Member State Greece for the pesticide active substance kieselgur (diatomaceous earth) and the considerations as regards the inclusion of the substance in Annex IV of Regulation (EC) No 396/2005 are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012, as amended by Commission Implementing Regulation (EU) No 2018/1659. The conclusions were reached on the basis of the evaluation of the representative uses of kieselgur (diatomaceous earth) as an insecticide and acaricide on stored cereals, empty storage rooms and storage rooms, mills and warehouses (with stored goods). The reliable end points, appropriate for use in regulatory risk assessment, are presented. Missing information identified as being required by the regulatory framework is listed.
Sensitivity analysis of gravity gradient inversion of the Moho depth—a case example for the Amazonian Craton

We present a novel approach for linearized gravity inversion to estimate the Moho depth, which allows the use of any gravitational component instead of the vertical gravity component only. The inverse problem is solved with the Gauss–Newton algorithm and the gravitational field of the undulating Moho depth is calculated with tesseroids. Hereby, the density contrast can be laterally variable by using information from seismological regionalization. Our approach is illustrated with a synthetic example, which we use to explore different regularization parameters. The vertical gravity gradient gzz provides the most reasonable results with appropriate parameters. As a case example, we invert for the Moho depth of the Amazonian Craton and its surroundings. The results are constrained by estimates from active seismic measurements. Our new Moho depth model correlates to tectonic domains and is in agreement with previous models. The estimated density contrasts of the tectonic domains agree well with the lithospheric architecture and show with 300–450 kg m–3 lower density contrasts for continental domains, whereas the oceans reveal a density contrast of 450–500 kg m–3. The wider range of estimated density contrast for the continent reflects uncertainties in Precambrian Fold Belts that arise from its small gravity signal. Our results demonstrate that a variable density contrast at the Moho depth is a valuable enhancement for gravity inversion.
Mapeamento de QTL para contedos de protena e leo em soja

The objective of this study was to detect and map quantitative trait loci (QTL) affecting soybean (Glycine max L. Merr.) protein and oil contents. F2 plants, derived from the cross between the CS3032PTA276 line and the variety UFVS2012, were grown in a greenhouse and provided the leaves for DNA extraction and analysis. Forty-eight polymorphic microsatelite markers (SSR) were evaluated in the F2 population. Evaluation of the phenotype was performed in 207 families from F2:3 progenies, in a complete block design with three replicates, carried out in Vicosa, MG, Brazil, in 2006. Four QTL associated with protein content, in linkage groups D1a, G, A1, and I, and three QTL for oil content in groups A1, I and O were identified. Phenotypic variation for protein and oil explained by QTL ranged from 6.24 to 18.94% and 17.26 to 25.93%, respectively. New QTL associated with protein and oil contents were detected, besides those previously reported in other studies. Other regions may be involved in the genetic control of protein and oil contents in soybean besides those already known.
Confidence Interval Based Distributionally Robust Real-Time Economic Dispatch Approach Considering Wind Power Accommodation Risk

This article proposes a confidence interval based distributionally robust real-time economic dispatch (CI-DRED) approach, which considers the risk related to accommodating wind power. In this article, only the wind power curtailment and load shedding due to wind power disturbances are evaluated in the operational risk. The proposed approach can strike a balance between the operational costs and risk even when the wind power probability distribution cannot be precisely estimated. A novel ambiguity set is developed based on the imprecise probability theory, which can be constructed based on the point-wise or family-wise confidence intervals. The worst pair of distributions in the established ambiguity set is then identified, and the original CI-DRED problem is transformed into a determined nonlinear dispatch problem accordingly. By using the sequential convex optimization method and piecewise linear approximation method, the nonlinear dispatch model is reformulated as a mixed integer linear programming problem, for which off-the-shelf solvers are available. A fast inactive constraint filtration method is also applied to further relieve the computational burden. Numerical results on the IEEE 118-bus system and a real 445-bus system verify the effectiveness and efficiency of the proposed approach.
Nonlinear optical properties of anisotropic two-dimensional layered materials for ultrafast photonics

Abstract The discovery of graphene has intrigued the significant interest in exploring and developing the two-dimensional layered materials (2DLMs) for the photonics application in recent years. Unlike the isotropic graphene, a number of 2DLMs possess the in-plane anisotropic crystal structure with low symmetry, enabling a new degree of freedom for achieving the novel polarization-dependent and versatile ultrafast photonic devices. In this review article, we focus on the typical anisotropic 2DLMs including BP, ReS2, ReSe2, SnS, and SnSe and summarize the recent development of these anisotropic 2DLMs in the pulsed laser and the optical switch applications. First, we introduce the fabrication methods as well as the material characterization of the anisotropic 2DLMs by analyzing the polarized Raman configuration. Second, we discuss the anisotropic nonlinear optical properties of the anisotropic 2DLMs and concentrate on the anisotropic nonlinear absorption response. Next, we sum up state of the art of the anisotropic 2DLMs in the application of pulse lasers and optical switches. This review ends with perspectives on the challenge and outlook of the anisotropic 2DLMs for ultrafast photonics applications.
Electronic and mechanical design of a hexapod land searching robot

In this study, it is aimed to design a robot that can be used in fields such as land exploration, mine search, ammunition transportation, search and rescue activities in natural disasters. For this purpose, a six-legged robot was designed. The robot can move evenly in uneven terrain conditions, stop, accelerate and overcome the obstacle when it sees an obstacle. The mechanical and electronic design of the robot was realized, and a prototype was manufactured. The flexibility of the legs used in the design ensures that the robot can move more easily in field conditions. The synchronous speed and direction of the motors are controlled, and the robot moves in a balanced way. With the IP camera mounted on a Raspberry Pi, snapshots were taken from the robot. Mechanical and electronic design of six-legged robot capable of moving on uneven ground was realized. The six-legged robot was placed with three legs on the right and three legs on the left. The motors were operated simultaneously to allow the robot to move evenly. Thanks to its leg structure, it was aimed to travel in land conditions. Image control was provided on the computer with the camera placed on the robot. In this study, the program written into the electronic cards run the motors simultaneously.
Heterogeneity, Transfer Progressivity, and Business Cycles

This paper studies how transfer progressivity influences aggregate fluctuations when interacted with household heterogeneity. Using a simple static model of the extensive margin labor supply, we analytically characterize how transfer progressivity influences differential labor supply responses to aggregate conditions across heterogeneous households. We then build a quantitative dynamic general equilibrium model with both idiosyncratic and aggregate productivity shocks and show that the model delivers moderately procyclical average labor productivity and a large cyclical volatility of aggregate hours relative to output. Counterfactual exercises indicate that redistributive policies have very different implications for business cycle fluctuations, depending on whether tax progressivity or transfer progressivity is used. Finally, we provide empirical evidence on the heterogeneity of employment responses across the wage distribution, which supports the key mechanism of our model.
Impact Dynamics of a Dragonfly Wing

: The lift force was reported not to be high enough to support the dragonfly’s weight during flight in some conventional investigations, and higher lift force is required for its takeoff. In this study, by employing a thin plate model, impact effect is investigated for the wing deformation in dragonfly flapping during takeoff. The static displacement is formulated to compare with the dynamical displacement caused by impact. The governing equation of motion for the impact dynamics of a dragonfly wing is derived based on Newton’s second law. Separation of variables technique and assumed modes method are introduced to solve the resulting equations. Further, lift force is presented for the cases of considering and without considering the impact on the wing flapping which indicates that the impact has prominent effects for the dragonfly’s aerodynamic performance. Numerical simulations demonstrate that considering the impact effect on the wing flapping can increase the wing deformation, which results in the rise of the lift force. The enhanced lift force is of critical importance for the dragonfly’s takeoff.
Climate variability over the reef corridor of the southwestern Gulf of Mexico

Local and regional climate trends drive rates of change in coastal ecosystems. To better understand local climate, 35-year-long time series of air temperature, relative humidity and rainfall were analyzed along the reef corridor of the southwestern Gulf of Mexico. Data came from a climatological model and to assess its local performance, differences with in situ records were estimated when available. All three variables showed coherence with the record of the North Atlantic high-pressure system (also known as the Bermuda High) at similar times and periods between 4 to 8 and >10 years, evidencing the influence, at this regional scale, of El Nino Southern Oscillation (ENSO) and the Atlantic Multidecadal Oscillation (AMO). Positive and negative anomalies showed linear trends depicting an increase of warmer and moister events during a seasonal climatology at the reef corridor of the southwestern Gulf of Mexico and a relatively higher correlation (> 0.5) with the AMO mode. Return periods of extreme values varied between 5 and 10 years. In general, trends and extreme events showed similar patterns at a regional scale, but the increase in rainfall is expected to be larger near the central location of the study area. A higher frequency of extreme events could threaten local ecosystems and human populations; therefore, plans and actions at local scales of governance are needed to achieve preemptive climate adaptation.

The Transient and Intermittent Nature of Slow Slip

To first order, faults are locked while stress builds up to a devastating earthquake. However, we know that faults also slip slowly. After decades of geophysical observation, slow slip is now recognized as part of a continuum of transient deformation ranging from the dynamic propagation of seismic rupture to aseismic events over a wide range of durations and sizes. A growing body of evidence suggests that large‐scale slow slip events can be decomposed into a multitude of smaller, temporally clustered events. Slow slip is more frequent and more dynamic than is suggested by conceptual models of rate‐strengthening, stable slip.
Whole exome analysis of primary immunodeficiency

The human primary immunodeficiency diseases (PIDs) refer to a rare heterogeneous group of single-gene inherited disorders causing malfunctions in the immune system, and thus the affected patients have a predisposition to severe life-threatening infections. The heterogeneous nature of PIDs, which involves at list 300 different genes, makes diagnosis of the disease a complex issue. Although studies revealed that six million people have a kind of PID, but due to a complex diagnosis procedure many affected individuals have not gotten a correct diagnosis. However, thanks to advancing in the DNA sequencing method and availability of sophisticated sequencers molecular characterization of genetic disorders have been revolutionized. The whole exome sequencing (WES) method can help clinicians detect Mendelian disease and other complex genetic disorders. The presented study used WES to investigate two infants with symptoms of primary immunodeficiency including hemophagocytic lymphohistio­cytosis (HLH) and severe combined immunodeficiency (SCID). It has been shown that the HLH patient had a mutation in the UNC13D gene (NM_199242.2:c.627delT), and the SCID patient had a mutation in the RAG1 gene (NM_000448.2:c.322C>G). It has been demonstrated that WES is a fast and cost-effective method facilitating genetic diagnosis in PID sufferers.
