Enhanced PSK-LoRa

This letter introduces enhanced phase shift keying Long Range (ePSK-LoRa) as an alternative to classical modulation approaches for low power wide area networks. By employing different combinations of phase and frequency shifts of the orthogonal chirp and using signal averaging, ePSK-LoRa achieves higher energy efficiency and higher spectral efficiency (SE) relative to the state-of-the-art schemes. Besides comprehensively elucidating the orthogonality of the transmitted symbols, we present maximum likelihood and absolute value detectors. The simulation results depict that besides affording higher SE, ePSK-LoRa requires lower signal-to-noise ratio per bit for correct detection making it a viable alternative to the classical approaches.
Automated gust front detection using knowledge-based signal processing

The latest airport surveillance radar, enhanced with a wind shear processor (ASR-9 WSP), is being developed as a less expensive alternative weather radar. Although gust fronts are visible to human observers in ASR-9 WSP imagery, the lower sensitivity and less reliable Doppler measurements of this radar make automated gust front detection a much more challenging problem. Using machine intelligence and knowledge-based signal processing techniques developed in the context of automatic target recognition, a machine intelligent gust front algorithm (MIGFA) is constructed that is radically different from previous algorithms. Developed initially for use with ASR-9 WSP data, MIGFA substantially outperforms a state-of-the-art gust from detection algorithm based on earlier approaches. These results also indirectly suggest that MIGFA performance may be nearly as good as human performance. Preliminary results of an operational test period (two months, approximately 15000 scans processed) are presented. <<ETX>>
Multimode Bridge Response to Wind Excitations

Spectral analysis of random vibration is used to develop a new multimode linear theory for the computation of cross‐spectra of bridge response to turbulent wind excitations. New interpretations are given to previous works in the literature, and the results compared. The comparison enables a direct utilization of previously obtained experimental results, as well as clarification of the implication and limitation of previously proposed simplified procedures. Since the average wind velocity is used to formulate the self‐excited loads, with the effects of turbulence on these loads neglected in the analysis, the present theory may not be applicable at the proximity of flutter instabilities.
Sleep quality and life satisfaction of railway employees

The aim of the study was to examine the relationship between sleep quality and life satisfaction. The basic hypothesis was that the dimensions of quality and quantity of sleep will be statistically significant predictors of life satisfaction among employees of the Serbian Railways. A total of 126 workers working in different jobs were surveyed: dispatcher, information worker, cashier, train driver, and conductor. Respondents differed according to gender, age, and years of service. The main research variables were operationalized by The Pittsburgh Sleep Quality Index (PSQI; Buysse et al., 1989) and the Satisfaction Life Scale (SWLS; Diener et al.,1985). The results showed that based on the regression model consisting of sleep quality modalities, the criterion variable - life satisfaction (R2 = .40, p <0.01) can be statistically significantly explained. The largest individual contribution to the prediction of the criterion variable has the predictor of dysfunction during the day (b = -. 42, p <0.01), followed by sleep disorders (b = -. 22, p <0.05) and sleep duration (b = -. 22, p < 0.01). Examination of differences with respect to some sociodemographic variables showed that women show poorer quality of sleep, and that the quality of sleep decreases with age, that more sleep disorders occur, which causes dysfunctions during the day and more frequent use of medications.
20 W linear, high efficiency internally matched HBT at 7.5 GHz

An internally matched HBT has been developed for use in communications systems. An output power of 20 W with 6.5 dB gain and 40% PAE at 7.5 GHz was achieved. Over the 7.25 to 7.75 GHz band minimum output power was 16.5 W with minimum 38% PAE. Two tone testing showed good linearity. <<ETX>>
Examining weekly facilitated group sessions and counselor‐crafted self‐monitoring feedback on treatment outcome in digital weight control: A pilot factorial study

Weight control programs that incorporate group sessions produce greater weight losses, but this has not been explored in the context of online programs. Further, counselor‐crafted self‐monitoring feedback is a core element of lifestyle interventions, although pre‐scripted, modular feedback which does not require detailed counselor review may adequately promote weight loss. The current study explored the weight losses achieved in an online program that included facilitated group sessions, as well as outcomes when counselor‐crafted self‐monitoring feedback was provided.
Statistical and Dynamical Climate Predictions to Guide Water Resources in Ethiopia

AbstractClimate predictions with lead times of one season or more often provide prospects for exploiting climate-related risks and opportunities. This motivates the evaluation of precipitation prediction techniques from statistical and dynamical models, and their combination, to potentially augment prediction skill over the Blue Nile Basin in Ethiopia. This work considers to what degree greater skill or reliability in a particular prediction technique translates through hydropower management models given their nonlinear response. One hundred precipitation series from 1981–2000 are generated to compare prediction techniques. The linked multimodel ensemble climate forecast/hydropower system proves superior to the statistical and dynamical prediction technique linked systems across a range of metrics. This includes an expected increase in annual benefits by $4–5–million on average. The climate forecast/hydropower system is sufficiently flexible to allow water managers to attain an optimal balance between ben.
Magnetic resonance spectroscopy as a promising modality for assessing ketogenic diet impact on the level of cerebral metabolites in the treatment of certain neurological disorders.

INTRODUCTION AND OBJECTIVE The ketogenic diet (KD) is a high-fat, adequate-protein, low-carbohydrate diet that is getting more and more widespread in medicine. This dietary intervention causes changes in cerebral metabolism, which are considered potentially beneficial in patients with neurological disorders, but its impact should be controlled and assessed individually. The aim of this review is to provide an update of existing evidence concerning the utility of magnetic resonance spectroscopy (MRS) in monitoring shifts in the cerebral metabolism during ketogenic diet in patients with neurological disorders. REVIEW METHODS The latest available literature was reviewed by May 13, 2021 using the PubMed, Web of Science and Google Scholar databases. There were 13 papers selected for analysis after reading the title, abstracts and whole text, meeting the assumed criteria. ABBREVIATED DESCRIPTION OF THE STATE OF KNOWLEDGE MRS is a non-invasive imaging method providing information about the metabolism of brain tissues and playing an increasingly important role in monitoring the concentrations of cerebral metabolites in the course of such neurological disorders as primary brain tumour, epilepsy during KD. Recent trials prove that inverse correlation between serum β-hydroxybutyrate levels and N-acetylaspartate in brain tissue confirm antiepileptogenic properties of KD. Furthermore, ketone concentrations including β-hydroxybutyrate and acetone in both lesional and contralateral brain are referred to as correlating with average ketonuria in patients with primary brain tumou. SUMMARY MRS is a feasible tool for detecting cerebral metabolic shifts linked to a ketogenic diet. However, further studies confirming MR spectroscopy utility in monitoring ketogenic diet treatment in patients with neurological disorders are needed.
Studying Variations in Culture and Literature: Visualizing Translation Variations in Shakespeare's Othello

Shakespeareâ��s Othello, along with much of his other work, has been translated by many people over the last 300 or so years. The variations in these translations provide a powerful platform to study the literature in more detail, as well as the changes in culture and society over time. Further, recent developing phenomenon on the Web now provide new technologies and opportunities to study these varying translations at global scale, as well as creating a domain to further study the evolving Web. This paper describes a new project that aims to leverage recent developments in the Web to help understand both literature and cultural history in unprecedented ways. We believe that our work can then generalize to other literature.
Roles of Managers and Stakeholders Perception on Solar Technology Adoption Intention: A Case of Micro, Small and Medium Enterprises (MSMEs) in Lagos State, Nigeria

Powers shortages is rampant in Africa of which Nigeria is not an exception and solar technology as a viable alternative source of electricity which would mitigate this problem has meted slow adoption. This study aimed to explore the impact of mindset/attitude from Theory of planned behavior (TPB), Disruptive Innovation Theory (DIA), awareness-knowledge, opportunity and barrier over managers (owners) of MSMEs intention to adopt solar technology for their businesses. A questionnaire was administrated to collect data from a sample of 400 managers (owners) of MSMEs respondents’ in Lagos State, Nigeria. A multivariate technique was applied to test the hypotheses using Structural Equation Modeling (AMOS-23). The findings showed that mindset/attitude, (DIA) and opportunity have a significant impact on solar technology intention, however, awareness-knowledge and barrier were not significant. These independent variables explained 71% variance of the dependent variable intention. In addition, DIA was found to have a significant impact on opportunity, barrier and mindset/attitude however, barrier on mindset/attitude was not significant. These findings not only provide evidence for MSMEs strategic planning to ensure sustainable business growth for their businesses but also provide new knowledge to policy and decision makers, the manufacturing & installation (suppliers) companies and other stakeholders for renewable energy as a part of long term sustainable development.

Accuracy analysis of GO/UTD radio-channel modeling in indoor scenarios at 1.8 and 2.5 GHz

Ray-tracing techniques have been widely used as simulation tools for the design and planning of wireless systems, both in urban microcells and in indoor picocells, due to the site-specific nature of those environments. However, the value of such tools depends on the accuracy of the predictions when compared to measurements in real-world propagation environments. In this paper, the accuracy of a ray-tracing technique based on a full three-dimensional implementation of GO/UTD is analyzed, by comparison between measurements and simulations carried out for different indoor wireless-propagation environments and in different frequency bands. The narrowband analysis shows that both the mean level of the received signal and the statistical behavior of its variations about the mean can be accurately estimated. In the wideband analysis, the comparison between measured and simulated power-delay profiles shows that both the amplitude and arrival times of the main multipath components can be well predicted. The statistical distributions of the measured and simulated wideband parameters are also compared, showing good agreement.

Comparison of driving performance on-road and in a low-cost simulator using a concurrent telephone dialling task

Driving performance in an instrumented vehicle was compared with performance in a low-cost, fixed-based driving simulator. Six men and six women drove a freeway route while periodically dialling simulated phone calls. The same subjects drove a laboratory driving simulator using two visual fidelity levels: a colour scene with relatively high detail, and a monochrome (night) scene showing only road-edge markings. Lane position, speed, steering-wheel angle and throttle position were recorded in both contexts. Lane-keeping in the simulator was less precise than on the road, but speed control performance was comparable. The SD of lane position in normal driving was about twice as large, on average, in the simulator (0.360 versus 0.165 m). Lane keeping and speed control were less precise when dialling the phone than in normal driving, both in the simulator and on the road, but the performance decrement was greater in the simulator. The addition of the phone task increased the mean lateral speed in the car by ab.
Remote sensing image uneven haze removal based on correction of saturation map

Abstract. Remote sensing images are frequently affected by the random haze. An efficient method to remove uneven haze is proposed based on dark channel prior (DCP) corrected by saturation map and atmospheric haze model with consideration of multiple atmospheric scattering effects. First, the non-negligible atmospheric multiple scattering phenomenon is simulated by atmosphere point spread function, and the atmospheric multiple scattering haze model is established. Second, an effect method is proposed to calculate the saturation map to correct the DCP, which is used to eliminate the intensity residual of remote sensing images and re-establish the transmission calculation formula. Finally, the image is entered into the integrated restoration framework to remove the haze. Due to the correction of the saturation map, this method can effectively remove the inhomogeneous haze and retain detailed information in the haze-free areas. Compared with other excellent dehaze approaches, qualitative and quantitative experiments are carried out to demonstrate that the proposed method can effectively recover scenes in hazy regions and can retain more detailed information in haze-free regions.
Inhibition of Bruton’s Tyrosine Kinase Activity Attenuates Hemorrhagic Shock-Induced Multiple Organ Dysfunction in Rats

Objective: The aim of this study was to investigate (a) the potential of the Bruton's tyrosine kinase (BTK) inhibitors acalabrutinib and fenebrutinib to reduce multiple organ dysfunction syndrome (MODS) in acute (short-term and long-term follow-up) hemorrhagic shock (HS) rat models and (b) whether treatment with either acalabrutinib or fenebrutinib attenuates BTK, NF-κB and NLRP3 activation in HS. Background: The MODS caused by an excessive systemic inflammatory response following trauma is associated with a high morbidity and mortality. The protein BTK is known to play a role in the activation of the NLRP3 inflammasome, which is a key component of the innate inflammatory response. However, its role in trauma-hemorrhage is unknown. Methods: Acute HS rat models were performed to determine the influence of acalabrutinib or fenebrutinib on MODS. The activation of BTK, NF-κB and NLRP3 pathways were analyzed by western blot in the kidney. Results: We demonstrated that (a) HS caused organ injury and/or dysfunction and hypotension (post-resuscitation) in rats, while (b) treatment of HS-rats with either acalabrutinib or fenebrutinib attenuated the organ injury and dysfunction in acute HS models and (c) reduced the activation of BTK, NF- kB and NLRP3 pathways in the kidney. Conclusion: Our results point to a role of BTK in the pathophysiology of organ injury and dysfunction caused by trauma/hemorrhage and indicate that BTK inhibitors may be repurposed as a potential therapeutic approach for MODS after trauma and/or hemorrhage.
Design of a novel compact broadband patch antenna using binary PSO

In this article, a C‐Band broadband patch antenna is designed. The binary particle swarm optimization (BPSO) combining with IE3D software is adopted to broaden the bandwidth of the patch antenna automatically. Characteristics of the antenna are calculated using the well‐known Zeland IE3D software package while the bandwidth characteristic of the antenna is optimized using BPSO technique. The comparison results show that the 3.2% impedance bandwidth (4.63–4.78 GHz) of the patch antenna is upgrade to 10.4% (4.47–4.96 GHz) through the BPSO‐IE3D method. The antenna gain is stable and the radiation patterns are similar in configuration over the whole operating frequencies to that of a conventional patch antenna. A prototype of the optimized antenna has been fabricated and important antenna parameters such as reflection coefficient (S11) parameter, gains and radiation patterns are measured using Network Analyzer and antenna test‐bench. The measured values of the antenna parameters are found to match well with that of the simulated results, all of which illustrate that the method is valid and the antenna can operate well. © 2011 Wiley Periodicals, Inc.

Period Product Insecurity, School Absenteeism, and use of School Resources to Obtain Period Products among High School Students in St. Louis, Missouri.

Menstrual hygiene management (MHM) among female students is a neglected public health issue in the U.S. This study documented period product insecurity, school absenteeism, and use of school resources to obtain period products among high-school students in St. Louis, MO. Female students completed an anonymous, self-administered survey in English (n = 119). Descriptive statistics were used to determine the prevalence of period product need, resources used to obtain period products, and period-related absenteeism. The mean age of participants was 15.78 ± 1.28. Nearly two-thirds (64.4% (95% CI 55.1%-73.0%)) reported period product insecurity. Two-thirds (66.9% (95% CI 57.7%-75.3%)) reported using at least one of the school's resources to obtain period products. One-third of the participants (33.6% (95% CI 25.0%-43.1%)) reported missing school due to a lack of period products. School nurses need to be cognizant of how MHM affects their students' attendance at school and what measures they can take to help reduce menstruation-related absenteeism.
Does strategic knowledge matter? Effects of strategic knowledge about drawing on students’ modeling competencies in the domain of geometry

ABSTRACT We investigated how students’ strategic knowledge about situational (pictorial) drawings and mathematical (schematic) drawings affects drawing accuracy and modeling competencies in the domain of geometry. We conducted a pre-posttest experimental study with 473 students in grade 9. Students were randomly assigned to one of three treatment conditions in which we used a 90-minute intervention to promote strategic knowledge about situational drawing (EG1), strategic knowledge about mathematical drawing (EG2), or strategic knowledge about situational and mathematical drawing (EG3). We also used a control group in which we did not promote any knowledge about drawing (CG). Results of a multilevel path analysis did not show a total effect of the strategic knowledge treatments on students’ modeling competencies. However, the results indicated an indirect effect: Students who participated in the treatments demonstrated higher modeling competencies than students in the control condition, and strategic knowledge and drawing accuracy were mediating variables. Moreover, students who constructed a more accurate situational or mathematical drawing for a modeling problem were more likely to solve this problem adequately. Our findings indicate that strategic knowledge is a necessary but not sufficient precondition for the construction of high-quality drawings and high modeling competencies in geometry.
