A Sliding Mode Observer Design for the Average State Estimation in Large-Scale Systems

In this letter the average state estimation problem on a large-scale system with only few gateway nodes available for measurements is solved as the design problem of a reduced-order sliding mode observer subjected to unmatched perturbations. Necessary and sufficient conditions to guarantee the exact estimation are derived. Still, even in the case such conditions are not fulfilled, the boundedness of the estimation error is proved. Finally, a criteria to minimize such bound, and a gain adaptation law to trade-off that bound and its convergence rate are provided. Neither the observer complexity nor the estimation error depend explicitly on the size of the system, thus making the approach scalable and computationally tractable. Simulations supporting the effectiveness of the proposed strategy and a comparison with other existing strategies are also provided.
Isolating Cuts, (Bi-)Submodularity, and Faster Algorithms for Global Connectivity Problems

Li and Panigrahi, in recent work, obtained the first deterministic algorithm for the global minimum cut of a weighted undirected graph that runs in time $o(mn)$. They introduced an elegant and powerful technique to find isolating cuts for a terminal set in a graph via a small number of $s$-$t$ minimum cut computations. In this paper we generalize their isolating cut approach to the abstract setting of symmetric bisubmodular functions (which also capture symmetric submodular functions). Our generalization to bisubmodularity is motivated by applications to element connectivity and vertex connectivity. Utilizing the general framework and other ideas we obtain significantly faster randomized algorithms for computing global (and subset) connectivity in a number of settings including hypergraphs, element connectivity and vertex connectivity in graphs, and for symmetric submodular functions.
Study on the trapping effects of sex pheromone traps against Ostrinia furnacalis

A comparative study was conducted on the efficiency of different types, different hanging height of traps and different color traps on capture of Ostrinia furnacalis. The result indicated that the water trap and the triangular trap had better trapping effects than bottle and wing traps. The average daily catches, weekly catches and total catches were 0.7, 12.7 and 46.3 respectively for the water trap, and 0.6, 10.3 and 41.3 respectively for the triangular trap. The more suitable hanging height of the triangular trap were 2.5 m and 2.0 m. The average daily catches, weekly catches and total catches were 0.7, 11.0 and 43.7 respectively for height of 2.5 m, and 0.6, 10.3 and 41.3 respectively for height of 2.0 m. The trapping effects with four colors, red, white, yellow and green did not differ significantly.
Twin-width III: Max Independent Set, Min Dominating Set, and Coloring

We recently introduced the notion of twin-width, a novel graph invariant, and showed that first-order model checking can be solved in time f ( d, k ) n for n -vertex graphs given with a witness that the twin-width is at most d , called d -contraction sequence or d -sequence, and formulas of size k [Bonnet et al., FOCS ’20]. The inevitable price to pay for such a general result is that f is a tower of exponentials of height roughly k . In this paper, we show that algorithms based on twin-width need not be impractical. We present 2 O ( k ) n -time algorithms for k -Independent Set , r -Scattered Set , k -Clique , and k -Dominating Set when an O (1)-sequence of the graph is given in input. We further show how to solve the weighted version of k -Independent Set , Subgraph Isomorphism , and Induced Subgraph Isomorphism , in the slightly worse running time 2 O ( k log k ) n . Up to logarithmic factors in the exponent, all these running times are optimal, unless the Exponential Time Hypothesis fails. Like our FO model checking algorithm, these new algorithms are based on a dynamic programming scheme following the sequence of contractions forward. We then show a second algorithmic use of the contraction sequence, by starting at its end and rewinding it. As an example of such a reverse scheme, we present a polynomial-time algorithm that properly colors the vertices of a graph with relatively given a graph G , report the largest distance in G between two We show how breadth-first search (BFS) can be mimicked, when replacing “traversing an edge” by “traversing a biclique all at once”. A subtlety of the algorithm, beside the necessary data structures to get Single-Source Shortest Paths sublinear in the total number of edges, lies in the fact that bicliques, contrary to single edges, can be traversed twice (once in both directions) before being
Wine Quality Versus Ripeness of Light-Sorted Carlos Muscadine Grapes

Carlos muscadine grapes ( Vitis rotundifolia Michx.) were separated nondestructively into four ripeness classes with a 9Berrymatic9 optical sorting unit equipped with 546- and 610-nm filters. Effective sorting into ripeness classes was evidenced by °Brix, total titratable acidity, pH, and Brix-acid ratio determined on juice samples. Wines made from each of the four classes of ripeness-sorted grapes and a control (unsorted) sample were evaluated by chemical, physical, and sensory methods. The wines from grapes of optimum ripeness (classes 2 and 3) were superior to wines from grapes in the control goup, underripe grapes (class 1), or slightly overripe grapes (class 4). These results emphasize the importance of grape ripeness to wine quality.
Visual Objects Tracking on Road Sequences Using Information about Scene Perspective Transform

The paper studies existing approaches and methods used in the task of objects tracking on video, which is one of the most important tasks facing both visual data analysis systems as a whole and road traffic control systems mounted on moving participants of the scene directly (including self-driving vehicles). The proposed approach is used for road scene perspective transform estimation, the search area location, and works in conjunction with a convolutional neural network for objects tracking. The proposed approach helps significantly increase tracking efficiency (on average 10 %, up to 20 % for certain object classes) on a subset of the road scenes videos shot from a moving vehicle and can be used in practice in environment perception modules mounted directly to vehicles.
Electric-Potential-Driven Pressure-Sensing Observation in New Hollow Radial ZnO and Their Heterostructure with Carbon

Many applications demonstrated for ZnO desire a high dielectric constant and quickly induced polarization properties with frequency. We present new hollow radial zinc oxide nanostructure and carbon-decorated hollow ZnO heterostructures, which greatly influence the dielectric and capacitive pressure-sensing properties after integrating in polyvinyldine fluoride matrix. The hollow zinc oxide nanostructure was realized by using a simple and cost-effective ambient temperature template-free synthesis process. Crystal structure was investigated by using X-ray diffraction and Raman spectroscopy and then correlated with high-resolution transmission electron microscopy, which reveals buckling of lattice fringes. Mimicking the wurzite structure of ZnO, the developed carbon-decorated hollow radial ZnO improved the dielectric constant ∼140 at 100 Hz and reinforcing efficiency >4 times that of hollow radial ZnO because of strong interfacial polarization. We demonstrated a simple design, fabrication, and testing of fle.
Shared decision making in pediatric dermatology: context, opportunities, and practical examples

Purpose of review Shared decision making (SDM) is an important part of patient-centered care. However, it is neither widely practiced nor researched in pediatric dermatology. In this article, we provide practical examples of how to engage in SDM in pediatric dermatology, and identify future areas of research. Recent findings Children and parents/guardians desire SDM in clinical encounters. The process is applicable to discussions of medical as well as surgical care. Additionally, SDM can help prepare children for the transition from pediatric to adult/general providers. Clinicians often want more guidance on its implementation, and there is a dearth of research on SDM or decision tools specific to pediatric dermatology. Summary SDM is underused and understudied in pediatric dermatology. This article highlights how to engage in SDM and presents opportunities for research and implementation in pediatric dermatology.
Healthcare is a Team Sport: Stress, Resilience, and Correlates of Well-Being Among Health System Employees in a Crisis

EXECUTIVE SUMMARY While the COVID-19 pandemic has added stressors to the lives of healthcare workers, it is unclear which factors represent the most useful targets for interventions to mitigate employee distress across the entire healthcare team. A survey was distributed to employees of a large healthcare system in the Southeastern United States, and 1,130 respondents participated. The survey measured overall distress using the 9-item Well-Being Index (WBI), work-related factors, moral distress, resilience, and organizational-level factors. Respondents were also asked to identify major work, clinical, and nonwork stressors. Multivariate regression was used to evaluate associations between employee characteristics and WBI distress score. Overall, 82% of employees reported high distress (WBI ≥ 2), with nurses, clinical support staff, and advanced practice providers reporting the highest average scores. Factors associated with higher distress included increased job demands or responsibilities, heavy workload or long hours, higher frequency of moral distress, and loneliness or social isolation. Factors associated with lower distress were perceived organizational support, work control, perceived fairness of salary cuts, and resilience. Most factors significantly associated with distress—heavy workloads and long hours, increased job demands, and moral distress, in particular—were work-related, indicating that efforts can be made to mitigate them. Resilience explained a small portion of the variance in distress relative to other work-related factors. Ensuring appropriate staffing levels may represent the single largest opportunity to significantly move the needle on distress. However, the financial impact of the COVID-19 pandemic on the healthcare system may represent a barrier to addressing these stressors.
Wandering behavior in children with autism spectrum disorder and other developmental disabilities

Purpose of review Approximately one in four children with autism spectrum disorder (ASD) ‘elope’ or wander away from supervision each year; however, many caregivers do not receive adequate information on how to address wandering behavior. The purpose of this review is to summarize the available research on elopement frequency, wandering patterns, and interventions to provide pediatricians and other childcare professionals with appropriate strategies to address wandering behavior. Recent findings Despite the high prevalence of wandering by children with ASD or other developmental disabilities, there is relatively limited research in this area. Recent research has identified common patterns and factors associated with risk of elopement and elopement frequency. Summary Pediatricians should counsel families on the common issues and intervention strategies related to elopement. By increasing awareness of wandering in children with ASD, caregivers can feel better prepared to make informed decisions regarding their child's wellbeing and safety.
MULTIPLE SOLUTIONS FOR A CLASS OF QUASILINEAR PROBLEMS WITH DOUBLE CRITICALITY KARIMA AIT-MAHIOUT, CLAUDIANOR O. ALVES AND PRASHANTA GARAIN

We establish multiplicity results for the following class of quasilinear problems (P ) { −∆Φu = f(x, u) in Ω, u = 0 on ∂Ω, where ∆Φu = div(φ(x, |∇u|)∇u) for a generalized N-function Φ(x, t) = ∫ |t| 0 φ(x, s)s ds. We consider Ω ⊂ R to be a smooth bounded domain that contains two disjoint open regions ΩN and Ωp such that ΩN ∩ Ωp = ∅. The main feature of the problem (P ) is that the operator −∆Φ behaves like −∆N on ΩN and −∆p on Ωp. We assume the nonlinearity f : Ω× R → R of two different types, but both behaves like e N N−1 on ΩN and |t| ∗t on Ωp as |t| is large enough, for some α > 0 and p = Np N−p being the critical Sobolev exponent for 1 < p < N . In this context, for one type of nonlinearity f , we provide multiplicity of solutions in a general smooth bounded domain and for another type of nonlinearity f , in an annular domain Ω, we establish existence of multiple solutions for the problem (P ) that are nonradial and rotationally nonequivalent.
Performance Studies and Review of Millimeter Wave MIMO Beamforming at 60 GHz

Millimeter wave systems offer high date rate due to huge bandwidth but suffers from poor link budget. This is due to the blockage of the millimeter wave signal by the obstacles of size comparable to that of the wavelength of the signal. Various analysis in improving the signal strength is reported. One of them suggests use of directional antenna which guarantees signal delivery if line of sight communication between the transmitter and receiver exists. The other alternative scheme is Multi Input Multi Output (MIMO) beamforming that uses the channel statistics to steer the beam thereby improving the multiplexing gain and beamforming gain. In this paper, extensive research work carried out by us in MMW MIMO at 60 GHz covering aspects related to MIMO fixed-beam, adaptive beam and multibeam beamformers addressing line-of-sight and non-line-of-sight channel for MMW 60 GHz system is reviewed. © 2015 The Authors.

Severe Acute Respiratory Infection Surveillance during the Initial Phase of the COVID-19 Outbreak in North India: A Comparison of COVID-19 to Other SARI Causes

Abstract Introduction World Health Organization proposes severe acute respiratory infection (SARI) case definition for coronavirus disease 2019 (COVID-19) surveillance; however, early differentiation between SARI etiologies remains challenging. We aimed to investigate the spectrum and outcome of SARI and compare COVID-19 to non-COVID-19 causes. Patients and methods A prospective cohort study was conducted between March 15, 2020, to August 15, 2020, at an adult medical emergency in North India. SARI was diagnosed using a “modified” case definition—febrile respiratory symptoms or radiographic evidence of pneumonia or acute respiratory distress syndrome of ≤14 days duration, along with a need for hospitalization and in the absence of an alternative etiology that fully explains the illness. COVID-19 was diagnosed with reverse transcription-polymerase chain reaction testing. Results In total, 95/212 (44.8%) cases had COVID-19. Community-acquired pneumonia (n = 57), exacerbation of chronic lung disease (n = 11), heart failure (n = 11), tropical febrile illnesses (n = 10), and influenza A (n = 5) were common non-COVID-19 causes. No between-group differences were apparent in age ≥60 years, comorbidities, oxygenation, leukocytosis, lymphopenia, acute physiology and chronic health evaluation (APACHE)-II score, CURB-65 score, and ventilator requirement at 24-hour. Bilateral lung distribution and middle-lower zones involvement in radiography predicted COVID-19. The median hospital stay was longer with COVID-19 (12 versus 5 days, p = 0.000); however, mortality was similar (31.6% versus 28.2%, p = 0.593). Independent mortality predictors were higher mean APACHE II in COVID-19 and early ventilator requirement in non-COVID-19 cases. Conclusions COVID-19 has similar severity and mortality as non-COVID-19 SARI but requires an extended hospital stay. Including radiography in the SARI definition might improve COVID-19 surveillance.

GENETIC AND NON GENETIC EFFECTS ON MASTITIS DISEASE IN FRIESIAN COWS

The data of 1388 productive records for 279 Friesian cows were studied during the period from 1987 to 2008 in dairy farm belonging to Faculty of Agriculture, University of Alexandria. The traits under study were total milk yield (TMY, kg), 305 day milk yield (305-dMY, kg), lactation length (LL, days), persistency of lactation (Per, kg), first service period (FSP, days), days open (DO, days), and mastitis score (M.Score). The model included the fixed effects of parity, year of calving, season of calving and age at first calving as fixed effects and errors. Mean of mastitis score was (0.023 ± 0.002). Analysis of variance showed significant effects (P< 0.0001) of parity, year of calving and age at first calving on mastitis score, while, non significant effects of season of calving on mastitis score. Heritability estimate for mastitis score was 0.119. Also, genetic correlation among mastitis score and all traits studied were positive, while, phenotypic correlation were lower positive and negative values. Also, estimated breeding values of mastitis score for cows, dams and sires were 0.022, 0.015 and 0.008, respectively. Additions, when the averages of the traits under the study increased the times of infection increased except persistency. Also, the present results showed that numbers of infected cows by mastitis were increased in multiparious, older ages at first calving and winter season.

In this article we describe two methods for acquisition and examination of the root architecture of trees in order to evaluate the possible influence on stand diversity and horizontal structure. The roots and belowground biomass in semi-arid areas of south Portugal can be understood as the main competition area for the trees so understanding of their growth and architecture is essential for understanding of growth, interaction among plants and finally the diversity of the stand.
DISPARITIES AMONG STROKE REHABILITATION

Ella Smith Professor Jareb and Professor Moras Honors Capstone 15 November, 2019 Are there disparities among stroke patient’s recovery due to ethnicity, socioeconomic status, location of residency, age, gender and/or amount, level and type of rehabilitation? Patients who suffer from a stroke end up losing some mobility in one or both sides of their body which hinders them from performing their daily functions. This makes strokes one of the leading causes of disability as well as the fifth leading cause of death in the United States (Pinel & Barnes, 2018). The lack of blood supply to the brain creates bodily dysfunction because of the decay of various neural tissues in the brain (Pinel & Barnes, 2018). Since strokes are one of the leading causes of disability, it is important and necessary that rehabilitation is aimed at helping those who suffer from strokes regain control over their daily operations. After a stroke has occurred, there are multiple rehabilitation options available, but there is a major discrepancy among whether ethnicity, socioeconomic status and location of residency inhibits one’s recovery or not. Some data suggests that there are pretty significant disparities in stroke outcomes in the United States with respect to ethnicity, socioeconomic status, geographical area, age, gender and type of rehabilitation, amount of rehabilitation, level of rehabilitation.
Effects of Phosphorus Fertilizer Rates on Soil Properties, Nodulation and Yield of Faba Bean (Vicia faba L.) Varieties in Lemu Bilbilo District of Arsi Zone, South Eastern Ethiopia

A field experiment was conducted on farmer’s field during the 2017 main cropping season at Lemu Bilbilo with the objectives to determine the response of faba bean varieties to different rates of phosphorus fertilizer on nodulation and yield components of faba bean and the interaction effect of both phosphorus and faba bean varieties on yield and yield components of faba bean. The treatments include three faba bean varieties (Tumsa, Gebelcho and Dosha) and five phosphorus levels (0, 10, 20, 30 and 40 kg P ha) from TSP. The experiment was laid out in a randomized complete blocked design with factorial arrangement of 3 x 5 =15 treatment combinations with three replications. Significantly (P< 0.05) higher total number of nodule, effective nodules and non-effective nodules were recorded from Tumsa variety. Number of nodules per plant, and biomass yield were significantly affected by main effect of varieties. Higher total number of nodules per plant (63), number of non-effective nodules per plant (7.82) and nodule volume per plant (1.57 cm) were obtained from application of 30 kg p ha. Higher biomass yield (14158 kg ha) and grain yield (6323 kg ha) were obtained from application of 40 kg P ha . Applications of different rates of P highly significantly (P<0.001) influenced on faba bean agronomic phosphorus use efficiency. Most of the parameters studied were positively correlated to biomass and grain yield of faba bean. Therefore, it can be concluded that application of 30 kg ha of P with faba bean varies was proved to be productive and superior both in grain yield as well as economic advantage and might be recommended for Lemu Bilbilo area. Further study should be repeated both over locations and years in order to give full recommendation for practical application.
Indigo dyeing wastewater treatment by eco-friendly constructed wetlands using different bedding media

AbstractMost natural and synthetic textile dyes, especially vat dyes, are resistant to degradation and decolorization by conventional treatment methods. In this study, the purification of synthetic textile wastewater containing commercial indigo dye by a green technological treatment system was investigated. A vertical-flow constructed wetland model comprising three different bedding materials, sand, gravel, and zeolite, was used to treat synthetic indigo dyeing wastewater. Treatment efficiency was evaluated by measuring color and pollution parameters such as chemical oxygen demand (COD), pH, oxidation–reduction potential, and electrical conductivity. According to the results, the constructed wetland system reduced color by up to 97% and lowered the COD by up to 62%. This study demonstrated that the constructed wetland system is a promising technique for purification of indigo dyeing textile effluents of COD and color as compared to conventional methods.
Utilization on the Removal Cd(II) and Pb(II) Ions from Aqueous Solution Using Nonliving Rivularia bulata Algae

In present study, biosorption and elimination of cadmium(II) and lead(II) ions from aqueous solution was evaluated using the algae nonliving biomass (Rivularia bulata) as easy availability, natural origin and biological sorbents. The effect of contact time and metal concentration on the adsorption capacity of metal ions was investigated. The maximum adsorption capacities for Cd(II) and Pb(II) were found to be 26.36 and 34.30 mg/g at the optimum conditions, respectively. The experimental data exhibit a good compliance with the pseudo second-order equation for Cd(II) and Pb(II) ions. Langmuir and Freundlich models were also applied to experimental equilibrium data to find the best adsorption isotherm and the values of R L for Cd(II) and Pb(II) were found to be 0.735 and 0.926, respectively. Weber-Morris and Urano-Tachikawa diffusion models were also applied to experimental equilibrium data. The results are showed that the algae biomass was effectively used as a sorbent for the removal of toxic metal ions from aqueous solutions.
