Simulated and experimental verification of the microwave dual-band metamaterial perfect absorber based on square patch with a 450 diagonal slot structure

In this paper, we designed a dual band metamaterial perfect absorber (MPA) for Ku band applications. The overall ultrathin layer of proposed absorber consists of square patch with 450 diagonal slot structure within a copper square patch which loaded on both sides of dielectric thickness 1.6 mm FR-4 substrate. The results show that designed MPA gives two absorption bands at 12.45 and 14.18 GHz and absorption rates are 99.73% and 99.87% respectively. The proposed dual-band absorber has a polarization sensitive characteristic, the absorption performance is almost changing with different polarization angles. Furthermore, resonance centres of two absorption bands can be adjusted by changing related parameters. The novelties of proposed structure are simple, easy fabricate, low cost, durable, suitable for real-time applications and long-term stability considering the fabrication technique and non-destructive measurement method. The dualband absorber can be used in practical applications such as bolometer, EM wave spatial filter and satellite communications.

Worth a Thousand Words: The Study of Visual Gendered Self-Presentation on Twitter

Abstract The picture superiority effect suggests that a single photograph can communicate a significant amount of political information to voters. Accordingly, politicians must make strategic choices in their self-presentation, particularly when considering how to respond to gender-based stereotypes. Strategic stereotype theory suggests that politicians will either emphasize or rescind gender-based stereotypes depending on whether they believe them to be advantageous to their political image. While the literature on gendered self-presentation is largely confined to television advertising, there is a growing literature focused on the online environment. In this research note, we develop a methodological framework to assess gender-based stereotypes in a purely visual environment. We test the framework using photographs from the Twitter feeds of the main party leaders in the 2018 Ontario election. The note concludes by reflecting on the methodological challenges of examining gender in visual political content online.
Bacoside-A exerts protective effect against Parkinson’s disease-induced functional damage in mice via inhibition of apoptosis and oxidative response

Purpose: To determine the effect of bacoside-A on Parkinson's disease (PD) in a rat model, and elucidate its mechanism of action. Methods: A rat model of PD was established by administration of 5 μL of 6-hydroxydopamine in ascorbic acid (0.1 %). Measurement of serum levels of inflammatory factors was carried out using enzyme-linked immunosorbent assay (ELISA) kits. Western blotting was used to assay Bax, cytochrome c and Bcl-2 in rat hippocampus. Results: Bacoside-A treatment significantly reduced PD-induced high turning values in rats (p < 0.05). Treatment with bacoside-A reversed PD-mediated suppression of serum activities of CAT and glutathione peroxidase (GPx). In bacoside-A-treated PD rats, dose-dependent suppression of acetylcholinesterase (AChE) and inducible nitric oxide synthase (iNOS) activities were observed (p < 0.05). Bacoside-A-treated PD rats significantly (p < 0.018) reduced interleukin (IL)-1β and IL-6 levels. Treatment of PD rats with bacoside-A effectively reduced levels of tumor necrosis factor (TNF)-α, NF-κB p65, (COX)-2 and p53 protein, and also reversed up-regulations of Bax, cytochrome C, caspase-3 and caspase-9. Conclusion: Bacoside-A exhibits a protective effect against Parkinson disease-induced oxidative damage and neuronal degeneration in rats through downregulation of iNOS, AChE, inflammatory cytokines and pro-apoptotic proteins. Therefore, bacoside-A has potentials for use in the management of Parkinson disease.
Strategic Value Creation through Enterprise Blockchain

Blockchain and other distributed ledger technologies have enormous potential for creating business value but have not yet been widely adopted. Enterprise blockchain systems are recognized as solutions to existing operational problems or ‘pain points’ but their potential for delivering value through strategic opportunities is not well understood. Drawing from literature on strategic alliances and the resource-based view of the firm, we identify avenues through which blockchain systems can contribute to a firm’s strategic capabilities and, as a result, to its sustained competitive advantage. We provide a framework for understanding how participation in blockchain solutions can enable companies to build upon existing strategic capabilities, strengthen collaborative capabilities and develop blockchain-specific capabilities. The framework can be useful to firms and service providers for incorporating strategic outcomes into the evaluation of blockchain investment opportunities.
Plastic mulching increased soil CO2 concentration and emissions from an oasis cotton field in Central Asia

Although previous researchers suggest that carbon dioxide (CO2) emissions are influenced by plastic mulching, the effects of this method on soil CO2 concentration and emissions remain uncertain. Soil CO2 concentration and emissions from ridge and furrow soils under mulched and nonmulched treatments in 2014 and 2015 were measured. The soil CO2 concentration was observed using modified diffusion equilibrium samplers, and the soil CO2 emissions were measured using a closed‐chamber method. In the ridge soil, although the plastic mulching increased the CO2 concentration by 49% (0–40 cm), no significant difference in CO2 emissions was found between the mulched and nonmulched treatments. Accordingly, the relationship between soil CO2 concentration and CO2 emissions was affected by plastic mulching, with a lower slope of the linear equation found in the mulched treatment compared to the nonmulched treatment. In the furrow soil, the plastic mulching increased the CO2 concentration and emissions by 15% and 21%, respectively. In conclusion, plastic mulching significantly increased the CO2 concentration in both the ridge and furrow soils and increased the cumulative CO2 emissions by 8%. The temperature sensitivity of the soil CO2 concentration increased with soil depth, whereas the plastic mulching only influenced the temperature sensitivity of the soil CO2 concentration in both the ridge and furrow soils at a depth of 40 cm. Our results suggest that the temperature sensitivity of the soil CO2 concentration not only reflects the effects of temperature on CO2 production but also indicates poor diffusion in the deep profile.
Noise analysis of a driven chain with an improved Howland current source for electrical impedance tomography

Driven chains, also called current injection blocks, are one of the main sub-blocks of electrical impedance tomography (EIT) systems. In most applications, the noise performance of a driven chain is a critical figure of merit, which limits the signal-to-noise ratio of an EIT system. Accurate noise analysis of driven chains with improved Howland circuits is still missing in the EIT literature. In this paper, an accurate noise model of a driven chain with an improved Howland current source for an EIT system is presented. Both simulated and lab-built driven-chain circuits are employed to validate our model. It is shown that the simulation and test results closely match. This work provides both an accurate noise model and a noise budget method for EIT driven chains with an improved Howland current source.
Following ICD-11, Rebuilding Mental Health Care for Transgender Persons: Leads from Field Experimentations in Lille, France

Psychiatrists have long been charged with access and coordination of care for transgender persons. This is now challenged by the World Health Organization's removal of diagnoses of mental illness related to gender identity in the 11th revision of the International Classification of Diseases. Using French field experimentations based on informal and primary care and free and informed consent, we discuss key challenges for a new organization of mental health care respectful of human rights. Developing informal and primary care as well as peer support has emerged as promising. Mental health expertise should be transferred from tertiary to secondary care.
Short-Form, Comedy Improv Affects the Functional Connectivity in the Brain of Adolescents with Complex Developmental Trauma as Measured by qEEG: A Single Group Pilot Study

Complex developmental trauma (CDT) is characterized by prolonged exposure to traumatic events in early life, resulting in the breakdown of neurobiological integration which impacts mental and physical health. The benefits of practicing short-form improvisation (improv), however, parallel the treatment needs of this population. To observe the neurobiological effect of improv, we used eyes-open quantitative electroencephalography (qEEG) to record the brains of 32 adolescents before and after participation in a 20-min intervention (One Rule Improv) consisting of short-form improv games. A paired t -test was used to evaluate coherence, phase, absolute amplitude, and low-resolution electromagnetic tomography (LORETA). Results indicated increases in coherence in delta, theta, alpha, and beta ( p < .05). Phase lag showed a statistical decrease ( p < .05) in delta, alpha, and beta. Absolute power showed significant increases in alpha frontally Fp1 ( p = .004), decreases in delta ( p = .030) at T4. LORETA analysis indicated significant changes in sensorimotor rhythm (SMR) at Brodmann area (BA) 6, t (27) = 6.1, p < . 05. Significant delta decreased at BA 6, BA 10, t (27) = 4.96, p < . 05; and BA 24, t (27) = 3.90. Significant delta decreased at BA 4, BA 3, and BA 40, t (27) = 4.35, p < . 05. Results indicate preliminary evidence supporting improv as an intervention capable of affecting functional connectivity changes in adolescents with CDT. For developmental trauma, these results may indicate improved capacity to make meaningful connections with others and create opportunities for neuroplastic
Capacity Limitations and Workplace Problems in Patients With Mental Disorders

Objectives: According to the bio-psycho-social health model of the WHO, chronic illness should not only be described at the level of symptoms, but in respect to capacity limitations. Methods: Patients with common mental disorders (N = 1143, n = 808 employed, n = 581 workplace problems) were investigated concerning their self-rated capacities (Mini-ICF-APP-S). Results: Employed patients reported better capacities than unemployed patients. Among the employed patients, those without workplace problems reported better capacities than those with workplace-problems. Different types of workplace-problems were related with specific capacity levels, for example, problems with bullying or conflicts were associated with lower interactional capacities (assertiveness, group integration, dyadic relations), whereas patients with over-taxation problems perceived lower levels of flexibility, competency, structuring of tasks, proactivity and endurance. Conclusions: The capacity self-rating Mini-ICF-APP-S can depict differentiated capacity profiles that may be indicative for specific types of workplace problems.
Brain Networks of Emotional Prosody Processing in a Foreign Language Versus Mother Tongue

Increased interest in the relationships between the brain and behavior over the past several decades has made brain network process of emotional prosody a topic of study in disciplines like neurology, psychiatry, neurolinguistics and neuroscience. Because emotional prosody has a key role to implication of timbre component, mood sense, and prosodic content. Also, it serves a highly important function for sense, the meaning to be reflected, and ability to provide effective communication. Therefore, the knowledge of how the emotional prosody sequence works in the brain will contribute to both language development and foreign language teaching as well as clinical evaluation of individuals with verbal communication difficulty. In the literature, neuroimaging and neurophysiological studies about investigating emotional prosody have produced controversial results in specifying similarities versus differences mother tongue acquisition and foreign learning neural networks. For this reason, this review study takes an interdisciplinary perspective to identify the neural networks of emotional prosody in mother tongue and foreign language learning process with different imaging modalities.
The role of app-based remote patient monitoring in reducing primary care clinician workload during the COVID pandemic: A prospective observational real world feasibility study.

Background COVID-19 has placed unprecedented strain on healthcare providers, in particular, primary care services. GP practices have to effectively manage patients remotely preserving social distancing. We aim to assess an app-based remote patient monitoring solution in reducing the workload of a clinician. Primary care COVID patients in West London deemed medium risk where recruited into the virtual ward. Patients were monitored for 14 days by telephone or by both the Huma app and telephone. Information on number of phone calls, duration of phone calls and duration of time spent reviewing the app data recorded.Results The amount of time spent reviewing one patient on the telephone only arm of the study was 490 minutes, compared with 280 minutes spent reviewing one patient who was monitored via both the Huma app and telephone. Based on employed clinicians monitoring patients, this equates to a 0.04 reduction of full-time equivalent staffing I.e. for every 100 patients, it would require 4 less personal to remotely monitor them. There was no difference in mortality or adverse events between the two groups.Conclusion App-based remote patient monitoring clearly holds large economic benefit to COVID-19 patients. In wake of further waves or future pandemics, and even in routine care, app-based remote monitoring patients could free up vital resources in terms of clinical team’s time, allowing a better reallocation of services.
Fifteen Years of HFC‐134a Satellite Observations: Comparisons With SLIMCAT Calculations

The phase out of anthropogenic ozone‐depleting substances such as chlorofluorocarbons under the terms of the Montreal Protocol led to the development and worldwide use of hydrofluorocarbons (HFCs) in refrigeration, air conditioning, and as blowing agents and propellants. Consequently, over recent years, the atmospheric abundances of HFCs have dramatically increased. HFCs are powerful greenhouse gases and are now controlled under the terms of the 2016 Kigali Amendment to the Montreal Protocol. HFC‐134a is currently the most abundant HFC in the atmosphere, breaking the 100 ppt barrier in 2018, and can be measured in the Earth's atmosphere by the satellite remote‐sensing instrument ACE‐FTS (Atmospheric Chemistry Experiment‐Fourier Transform Spectrometer), which has been measuring since 2004. This work uses the ACE‐FTS v4.0 data product to investigate global distributions and trends of HFC‐134a. These measurements are compared with a simulation of SLIMCAT, a state‐of‐the‐art three‐dimensional chemical transport model, which is constrained by global surface HFC‐134a measurements. The agreement between observation and model is good, although in the tropical troposphere ACE‐FTS measurements are biased low by up to 10–15 ppt. The overall ACE‐FTS global trend of HFC‐134a for the altitude range 5.5–24.5 km and 2004–2018 time period is approximately linear with a value of 4.49 ± 0.02 ppt/year, slightly lower than the corresponding SLIMCAT trend of 4.66 ppt/year. Using a simple box model, we also estimate the annual global emissions and burdens of HFC‐134a from the model data, indicating that emissions of HFC‐134a have increased almost linearly, reaching 236 Gg by 2018.
Primary cardiac CD5-positive diffuse large B-cell lymphoma:A case report and review of literature

Background：Primary cardiac CD5 positive diffuse large B-cell lymphoma (CD5+ DLBCL) is a rare subtype of DLBCL with many diagnostic challenges. The case is reported, along with a review of several characteristics of the disease. Case presentation：We described a 64-year-old female who presented with a 12-month history of cough, and a mass in the right atrium observed on imaging studies that extended into the right ventricle. Conclusions：CD5+ DLBCL was confirmed finally by pathological examination of the cardiac biopsy. The patient responded well to the modified R-CHOP regime. The poor prognosis factors include CD5 positive, non-GCB immunophenotype, myc, bcl-2 and bcl-6 gene rearrangements etc. Early diagnosis and aggressive treatment play a key role on improving the prognosis of primary cardiac CD5+ DLBCL.
Boundary vibration suppression for a flexible three‐dimensional marine riser against unknown sensor and actuator faults

In this article, boundary control strategy is adopted to suppress the vibration of a flexible three‐dimensional (3D) marine riser simultaneously against both sensor and actuator faults. The flexible 3D marine riser is a distributed parameter system modeled as partial differential equations. During normal operation of the system, all the system components will behave optimally. However, if the sensor and actuator appear fault, the system will work abnormally. While the sensor is faulty, the output signal of the sensor will have errors, and this error signal will be the input signal of the actuator. In terms of actuator fault, once the actuator appears fault problem, the actuator should make up for the fault and continue working for the sake of safety. In this work, the fault degree of sensors and actuators are unknown and the boundary control schemes using Nassbaum function are developed for fault compensation. The system stability is proven by introducing an appropriate Lyapunov function. Finally, the simulation results verify the accuracy of the proposed control laws.
Temporal Outlier Analysis

The main focus of this research is temporal data. Temporal data means data depends on time. A large number of applications generate a set of temporal data. For example, in our daily life there are different types of records such as credit, personal, financial, judicial, medical, etc. All depends on time. This highlights the need for a detailed organized study of temporal outlier analysis. Over the past decade, a great deal of research has been done on various types of temporal data, including consecutive data snapshots, a series of data snapshots, and data streams. In addition to initial work on time series, the researchers focused on rich data types that include multiple data streams, spatio-temporal data, network data, community distribution data, etc. Compared to general outlier analysis, the techniques for temporal outlier analysis are very different, such as AR models, Markov models, evolutionary clustering, etc.
Heterogenous effects of father and mother age on offspring development

Maternal age has long been described to influence a broad range of offspring life-history traits, including longevity. However, relatively few studies have tested experimentally for the effects of paternal age and even fewer the potential interactive effects of father and mother age on offspring life-history traits from conception to death. To tackle these questions, I performed a factorial experimental design where I manipulated the age of both male and female field crickets (Gryllus bimaculatus) and subsequently assessed their effects over the offspring’s entire lifetime. I found that, despite coming from larger eggs, the embryos of old females grew up at a slower rate, took more time to develop, and showed lower hatching success than those of young females. Offspring postnatal viability was unaffected by female age but, at adulthood, the offspring of old females were bigger and lived shorter than those of young females. Male age effects were mostly present during offspring postnatal development as nymphs sired by old males having increased early mortality. Moreover, father age strongly influenced the development of offspring adult personality as revealed by the shyer personality of crickets sired by an old male. My results indicate that father and mother age at reproduction have different effects that affect offspring traits at different stages of their development. The results further suggest that father and mother age effects could be mediated by independent mechanisms and may separately influence the evolution of aging.
Design and Performance Evaluation of a Home Energy Management System for Power Saving

In the context of the ongoing global warming, with environmental concerns regarding the greenhouse gas emissions due to our increasing energy consumption, smart energy management solutions have gained popularity as they have the potential to reduce our impact on the environment and also on our budgets. This paper proposes one of the most affordable designs for an autonomous, microcontroller-based demand-side energy management system to be installed in a home environment where it reduces the standby power consumed by the controlled devices. As a secondary function, it monitors and controls the lights to further save energy. The proposed system is designed to operate independently and also to limit the new wireless sources of electro-magnetic radiation introduced in the home environment. Six homes have been analyzed in terms of the measured energy consumption and to evaluate the energy management capabilities of the system, a prototype was built and tested. Promising results have been obtained and are detailed in the Results and Conclusion sections. A very low purchase price and good performance make this design a viable solution for intelligent home energy management, in today’s economic context.
Data(-)based ambivalence regarding NYC 311 data infrastructure

ABSTRACT In New York City, data documenting complaints made to 311 – the city’s municipal ‘customer service’ agency – are increasingly being analyzed by city agencies, politicians, activists, and residents to make sense of urban quality of life. This article examines the infrastructural and socio-cultural conditions that have shaped public dispositions regarding 311 data’s representativeness. It argues that while data-based metrics have become a privileged form of knowing in NYC governance, the databased infrastructural form of 311 inevitably sidelines certain people and problems. As communities throughout NYC have grappled with this tension, many New Yorkers have become increasingly ambivalent about the data’s value in reporting urban issues. Data(-)based ambivalence troubles the power imbalances that privilege quantitative ways of knowing over other ways of knowing, prompting communities to reposition data(-)based representations as rhetorical tools instead of objective or unbiased ones.
