Correlation between Post-Acute Electroconvulsive Therapy Alpha-Band Spectrum Power Increase and Improvement of Psychiatric Symptoms

The results of quantitative electroencephalography (qEEG) studies on electroconvulsive therapy (ECT) have been inconsistent, and indicators of the efficacy of ECT have not been clearly identified. In this study, we examined whether qEEG could be used as an indicator of the effect of ECT by measuring it during the course of treatment. We analyzed qEEG data before and after acute-phase ECT in 18 patients with schizophrenia, mood disorders, and other psychiatric disorders. We processed the qEEG data and compared the spectral power between the data acquired before and after ECT. The spectral power increased significantly after ECT in the delta, theta, and alpha bands. There was a strong significant correlation between the increase in the spectral power of the alpha band after acute ECT and improvement in the Brief Psychiatric Rating Scale score. Our results suggest that an increase in the alpha-band spectral power may be useful as an objective indicator of the treatment effect of acute ECT.
Influence of COVID-19 Pandemic Uncertainty in Negative Emotional States and Resilience as Mediators against Suicide Ideation, Drug Addiction and Alcoholism

This research uses structural equation modeling to determine the influence of uncertainty due to the COVID-19 pandemic as an independent variable in the negative emotional states and resilience (as mediating variables) vs. drug addiction, alcoholism, and suicide ideation as dependent variables in 5557 students from a public state university in Northern Mexico. The five variables are related through eight hypotheses and tested using partial least squares. We used an adapted questionnaire sent by email in May 2020. Findings show that uncertainty facing the COVID-19 pandemic had a direct and significant influence on negative emotional states and a significant inverse effect on resilience; in the trajectory, drug addiction and alcoholism, and suicide ideation are explained.
Bioactivity-Guided Single-Step Isolation of Stachyspinoside from Sideritis congesta by Centrifugal Partition Chromatography

Sideritis congesta is a plant native to Mediterranean countries. Infusions of this plant are used to treat various diseases. The anti-inflammatory potential of Sideritis species is widely known. However, the anti-inflammatory potential of an aqueous extract of S. congesta has not been investigated yet. In this study, the phytochemical composition and anti-inflammatory potential of different fractions of an aqueous extract from S. congesta using bioactivity guided fractionation via centrifugal partition chromatography (CPC) were determined. A CPC single-step isolation of a flavonoid stachyspinoside 1 from S. congesta is reported. In addition, a CPC fractionation protocol of the crude aqueous extract was developed. Three aqueous fractions (I, II, and III) of S. congesta were obtained, and their anti-inflammatory potential was evaluated with respect to their ability to inhibit the activity of COX-2 and NF-κB in vitro. Fraction I showed the highest COX-2 inhibition activity (92.3% inhibition at 0.1%). Fraction III showed the highest NF-κB inhibition activity (99.9% at 0.1%) among the CPC produced fractions. The structures of 3 compounds of fraction III could be identified and were validated by HPLC-PDA, HRMS, and NMR spectroscopy. Finally, the phenol, saponin, and flavonoid contents were quantified in the most potent CPC fractions (I and III).
Effect of alloying elements on the mechanical behavior and wear of austempered ductile iron

This paper treats the effect of alloying elements on the modification of the microstructure and properties of austempered ductile iron. The basic cast iron was elaborated in an induction furnace, its solidification shows a ferrite-pearlitic structure. This cast iron was alloyed with Mn, Ni, Mo and V. The samples were cast in the form of cylindrical bars of 22 mm in diameter and 300 mm in length. They have undergone a bainitic heat treatment type. Microstructures were characterized by optical microscopy, “SEM” and “XRD”. Tensile strength, hardness, microhardness, resilience and wear were determined and correlated with the microstructure. In the treated condition, metallographic study shows that the structures were formed of bainitic ferrite and feathery upper ausferrite. The results of mechanical tests and wear show that the cast irons studied achieve superior properties.
A COMPARISONBETWEENALTERNATIVEBEAMFORMINGSTRATEGIES FOR INTERFERENCECANCELATIONIN NOISY AND REVERBERANTENVIRONMENT

In speech communication systems the received microphone sig­ nals are often degraded by competing speakers, noise signals and room reverberation. Microphone arrays are commonly uti­ lized to enhance the desired speech signal. In this paper two im­ portant design criteria, namely the Minimum Variance Distor­ tionless Response (MVDR) and the Linearly Constrained Min­ imum Variance (LCMV) beamformers, are explored. These structures differ in their treatment of the interference sources. Experimental results using simulated reverberant enclosure are used for comparing the two strategies. It is shown that the LCMV beamformer outperforms the MVDR beamformer pro­ vided that the acoustic environment is time-invariant.
High-Sensitivity Distributed Bragg Reflector Fiber Laser Displacement Sensor

A high-sensitivity displacement sensor based on the integration of a dual polarization distributed Bragg reflector fiber laser with cantilever beam is demonstrated. The cantilever beam converts the displacement into a transverse force onto the fiber laser which results in a modulation in the fiber birefringence and hence the beat frequency of the laser. A sensitivity of 0.402 GHz/mm is implemented. The sensitivity dependence on the parameters of the transducer is investigated.
1 LCOS Spatial Light Modulators: Trends and Applications

Spatial light modulator (SLM) is a general term describing devices that are used to modulate amplitude, phase, or polarization of light waves in space and time. Current SLM–based systems use either optical MEMS (microelectromechanical system, [1]) or LCD technology [2]. In this chapter, we review trends and applications of SLMs with focus on liquid crystal on silicon (LCOS) technology. Most developments of liquid crystal (LC) microdisplays are driven by consumer electronics industry for rear–projection TVs, front projectors, and picoprojectors. Also,MEMS technologies such as digitalmicromirror device (DMD, [3]) and grating light valve (GLV, [4]) are driven by these industries, except for membrane mirrors. Some industrial applications have forced MEMS development for scanning, printing technologies, and automotive applications [5]. But the major R&D-related driving force for new SLM technologies is the defense industry. Technological advances in lithography are the basis for MEMS developments. Phase modulators based on 2D pistonlike mirror arrays [6, 7] or ribbonlike 1D gratings [8] show high performance in frame rate. Unfortunately, the availability of these technologies is limited because they are developed either company-internal or within defence projects. The major advantages of MEMS are frame rate, spectral range, and an efficient use of nonpolarized light. Phase modulators and other optical implementations are still niche markets for the MEMS industry. Even now, customized MEMS developments are quite challenging and expensive. LC panels still have an advantage out of their projection applications in terms of resolution and minimal pixel size for 2D displays. Only LC-based technology is able to modulate intensity, phase, and/or polarization because of polarization rotation and/or electrically controlled birefringence (ECB). LCOS technology [9] was developed for frontand rear(RPTV) projection systems competing with AMLCD (active matrix LCD) and DMD. The reflective arrangement due to silicon backplane allows putting a high number of pixels in a small panel, keeping the fill factor ratio high even for micrometer-sized pixels.
Material requirements planning in hierarchical production planning systems

Abstract Material requirements planning (MRP) is a way to develop the time phased material and other resource requirements to satisfy the needs of a master production schedule. Hierarchical production planning (HPP) is a framework for analysis and decision making in complex production environments. They are complementary approaches to the decision support system needs of multi-stage production systems. The hierarchical approach provides for efficient management review of proposed plans at corporate, plant, and shop levels while MRP provides a sound and detailed basis for understanding the implications of proposed plans and for executing the selected plan. The relationships between these two approaches are illustrated with an example application.
Relativistic Maxwell Theory and Einstein Field Equation derived from Variational Principle

In this article, I'll be reviewing relativistic mechanisms using the calculus of variation in the classical limit. The variational principle is considered to be one of the most important mechanisms to build a theory. Newton's second law of motion is a consequence of Euler-Lagrange equations which gives the least (or stationary) trajectory of a particle between any two arbitrary points. I'll the use action principle by deriving the relativistic Maxwell's field equation, geodesic equation, and Einstein's field equation.
COMBINED OPTIMIZATION OF SOYBEAN WATER PRODUCTIVITY AND CROP YIELD BY MULTI‐OBJECTIVE GENETIC ALGORITHM (MOGA)

One of the meta‐heuristic algorithms for multi‐objective optimization under conditions where there are more than one objective in research is the multi‐objective genetic algorithm (MOGA). The goal of this research is combined optimization of water productivity (WP) and crop yield under deficit irrigation management conditions. The data used in this study are the result of an experimental agricultural design conducted in the form of a randomized complete blocks design in three replications and seven water stress treatments at different growth stages in 2010 in Karaj. The results of this research show that in combined optimization under the first scenario conditions, the amounts of soybean optimum crop yield and optimum WP are 3830 kg ha−1 and 0.529 kg m−3 respectively. Also in combined optimization under the second scenario conditions, the amount of optimum crop yield and WP are 3840 kg ha−1 and 1.12 kg m−3 respectively. Copyright © 2013 John Wiley & Sons, Ltd.
Modelling multi-period customer-searching behaviour of taxi drivers

Various taxi network models have been developed to investigate the consequences of implementing taxi regulation policies. These models rely on logit-based taxi customer-search models to depict the customer-searching behaviour of drivers. However, very few studies have sought to validate the hypotheses on which the logit models are based, or to determine the factors that affect drivers’ customer-searching choices at different times of day. In this study, global positioning system (GPS) data from 460 urban taxis were used to validate the logit model and determine the factors underlying drivers’ searching behaviour. The analysis reveals that cross-zonal travel distance, intra-zonal circulating distance, relative passenger demand and rate of return affect the customer-searching decisions of the drivers of vacant taxis and that their searching behaviour varies with the time of day. The data also reveal that the cross-district search behaviour of vacant taxi drivers is strongly related to passenger demand over time and space. The drivers of vacant taxis tend to travel to high-demand districts during the mid-night period when overall demand is low, but they avoid crossing districts during high-demand peak hours.
A Comparison of Single- and Multiparametric MRI Models for Differentiation of Recurrent Glioblastoma from Treatment-Related Change

To evaluate single- and multiparametric MRI models to differentiate recurrent glioblastoma (GBM) and treatment-related changes (TRC) in clinical routine imaging. Selective and unselective apparent diffusion coefficient (ADC) and minimum, mean, and maximum cerebral blood volume (CBV) measurements in the lesion were performed. Minimum, mean, and maximum ratiosCBV (CBVlesion to CBVhealthy white matter) were computed. All data were tested for lesion discrimination. A multiparametric model was compiled via multiple logistic regression using data demonstrating significant difference between GBM and TRC and tested for its diagnostic strength in an independent patient cohort. A total of 34 patients (17 patients with recurrent GBM and 17 patients with TRC) were included. ADC measurements showed no significant difference between both entities. All CBV and ratiosCBV measurements were significantly higher in patients with recurrent GBM than TRC. A minimum CBV of 8.5, mean CBV of 116.5, maximum CBV of 327 and ratioCBV minimum of 0.17, ratioCBV mean of 2.26 and ratioCBV maximum of 3.82 were computed as optimal cut-off values. By integrating these parameters in a multiparametric model and testing it in an independent patient cohort, 9 of 10 patients, i.e., 90%, were classified correctly. The multiparametric model further improves radiological discrimination of GBM from TRC in comparison to single-parameter approaches and enables reliable identification of recurrent tumors.
High-Level Quinolone-Resistant Haemophilus haemolyticus in Pediatric Patient with No History of Quinolone Exposure

The prevalence of antimicrobial resistance among Haemophilus spp. is a critical concern, but high-level quinolone-resistant strains had not been isolated from children. We isolated high-level quinolone-resistant H. haemolyticus from the suction sputum of a 9-year-old patient. The patient had received home medical care with mechanical ventilation for 2 years and had not been exposed to any quinolones for >3 years. The H. haemolyticus strain we isolated, 2019-19, shared biochemical features with H. influenzae. However, whole-genome analysis found this strain was closer to H. haemolyticus. Phylogenetic and mass spectrometry analyses indicated that strain 2019-19 was in the same cluster as H. haemolyticus. Comparison of quinolone resistance–determining regions showed strain 2019-19 possessed various amino acid substitutions, including those associated with quinolone resistance. This report highlights the existence of high-level quinolone-resistant Haemophilus species that have been isolated from both adults and children.
Characterization of MIS structure coplanar transmission lines for investigation of signal propagation in integrated circuits

A full-wave analysis of metal-insulator-semiconductor (MIS) structure micron coplanar transmission lines on doped semiconductor substrates is carried out using a finite-difference time-domain approach. Metal conductor loss is taken into account in the analysis. Line parameters and electromagnetic field distributions are calculated over a wide frequency range involving slow-wave and dielectric quasi-transverse-electromagnetic mode limits. Measurements of these line parameters, varying substrate resistivity from 1 to 1000 Omega -cm, in the frequency range up to 40 GHz are also presented, and these agree with the analysis quite well. On the basis of these results, an equivalent circuit line model is induced and some considerations on the relationship between line structure and properties made. >
Shapes of Miura Mesh Mechanism with Mobility One

The Miura Ori is a mechanism composed by a polyhedral deployable surface. It has favorable qualities from engineering prospective that lead the growing interest on it. The present work focuses on its transmission of motion. The mechanism can be represented by spherical 4 bar linkages, and on this account a simple and effective mobility formula is presented. The mechanism having a number of excessive rigid members, it is also possible to remove all or some of them, variously arranged. The changes are included in the calculation of allowable mobility of the system. The resulting tool can be directly used for the design of deployable Miura Ori surfaces with customized shape.
An Approach towards IoT-Based Predictive Service for Early Detection of Diseases in Poultry Chickens

The poultry industry contributes majorly to the food industry. The demand for poultry chickens raises across the world quality concerns of the poultry chickens. The quality measures in the poultry industry contribute towards the production and supply of their eggs and their meat. With the increasing demand for poultry meat, the precautionary measures towards the well-being of the chickens raises the concerns of the industry stakeholders. The modern technological advancements help the poultry industry in monitoring and tracking the health of poultry chicken. These advancements include the identification of the chickens’ sickness and well-being using video surveillance, voice observations, ans feces examinations by using IoT-based wearable sensing devices such as accelerometers and gyro devices. These motion-sensing devices are placed over a chicken and transmit the chicken’s movement data to the cloud for further analysis. Analyzing such data and providing more accurate predictions about chicken health is a challenging issue. In this paper, an IoT based predictive service framework for the early detection of diseases in poultry chicken is proposed. The proposed study contributes by extending the dataset through generating the synthetic data using Generative Adversarial Networks (GAN). The experimental results classify the sick and healthy chicken in a poultry farms using machine learning classification modeling on the synthetic data and the real dataset. Theoretical analysis and experimental results show that the proposed system has achieved an accuracy of 97%. Moreover, the accuracy of the different classification models are compared in the proposed study to provide more accurate and best performing classification technique. The proposed study is mainly focused on proposing an Industrial IoT-based predictive service framework that can classify poultry chickens more accurately in real time.
Syrup Production from Sweet Sorghum

This paper presents pioneering developmental work on syrup production from sweet sorghum. A hybrid sweet sorghum „Madhura‟ has been developed which produces excellent syrup. This paper details the agronomy and the juice characteristics of this hybrid. Protocols for making excellent syrup from sweet sorghum are also outlined. Finally an economic analysis for syrup production is detailed. Sweet sorghum-an attractive feedstock for syrup making Sweet sorghum [Sorghum bicolor (L.) Moench] is the best multipurpose crop for simultaneous production of (i) grain from its earhead as food, (ii) sugary juice from its stalk for making syrup, jaggery or ethanol and (iii) bagasse and green foliage as an excellent fodder for animals, as biomass for gasification system, as organic fertilizer or for paper manufacturing. Moreover, sweet sorghum has a great tolerance to a wide range of climatic and soil conditions. It is a short duration crop of 110-130 days as compared to 12-18 months in sugarcane. In addition its water and fertilizer requirement is much less, resulting in lower cost of cultivation than sugarcane. Sweet sorghum is a plant with C4 photosynthetic pathway, so its photosynthetic rate and dry matter production in g/m 2 /day per unit of inputs are more than those of other sugar producing crops like sugarcane and sugarbeet. These characteristics make sweet sorghum an ideal crop for syrup and jaggery production. Existing sugar mills, small factories and „gurhals’ (jaggery-making units) running on sugarcane can be used during off-season for processing sweet sorghum (as it can be grown round the year as a supplementary feedstock) to make these units more economical. Like sugarcane syrup („kakvi‟ in Marathi), sweet sorghum syrup can be used as a liquid sweetener in various food products due to its excellent taste. It is a better source of calcium than honey. NARI has pioneered development of syrup and jaggery production from sweet sorghum in India. Sweet sorghum was introduced in India in early 1970s by NARI. Besides syrup production NARI also pioneered the production of ethanol from sweet sorghum. Consequently complete technology has been developed. „Madhura‟ - a sweet sorghum hybrid developed at NARI is recommended for round the year cultivation. It gives high quality grain and excellent fodder which can be fed to animals or used for producing natural, chemical-free, good quality, coloured syrup which at present is being marketed as „Madhura syrup‟. Its chemical composition compared to that of honey is given in Table 1.

Bandwidth enhancement of WWAN/LTE tablet computer antenna using embedded parallel resonant circuit

By embedding a printed parallel resonant circuit, the lower‐band bandwidth of the proposed internal tablet computer antenna is greatly enhanced.This bandwidth‐enhancement technique allows the proposed antenna to cover the eight‐band wireless wide area network/long term evolution operation in the 704–960 and 1710–2690 MHz bands with a small size of 12 × 60 × 3.8 mm3 in the tablet computer. The main radiator of the antenna comprises a patch monopole, a longer shorted strip, and a shorter shorted strip. The latter two shorted strips form the outer boundary of the antenna and are parasitically excited by the patch monopole. The parallel resonant circuit is formed by embedding a chip‐inductor‐loaded narrow strip in‐between the longer shorted strip and the patch monopole, with the narrow strip whose front terminal connected to the patch monopole and end section gap‐coupled to the longer shorted strip. This embedded circuit can lead to the generation of a parallel resonance seen at the antenna's feeding point. By controlling the parallel resonance to be at the high‐frequency tail of the resonant mode at about 800 MHz contributed by the longer shorted strip, an additional resonance can be generated, which can result in dual‐resonance excitation of the original single‐resonance mode. Thus, a wide antenna's lower band is obtained. Further, the patch monopole can contribute a resonant mode to combine additional resonant modes contributed by the two shorted strips to form a wide antenna's upper band. Details of the proposed antenna with the embedded parallel resonant circuit are described in the article. © 2011 Wiley Periodicals, Inc.

Salt effects on knot dynamics in polyelectrolyte solutions

ABSTRACT We study the dynamics of linear polyelectrolyte (PE) knot in solution with doping salt by molecular dynamics simulations. The molecular mechanisms of PE knot dynamics are explained. The knot dynamics are the coupling results by the moving effect of chain entanglement and by the breathing effect of knot fluctuations. The moving effect is important as the whole chain is in the random coil state and becomes weak as shrinking to the close-to-globule (CTG) state. Interestingly, as the chain in the CTG state, the knot swells with occupying more segments. The breathing effect dominates the knot dynamics in the CTG state. This nontrivial behaviour (in comparison to neutral polymer knot) is prominent for the cases of doping salt with high concentration or of doping high-valent salt, which attributes to the enhanced electrostatic interactions and long-range fluctuation effects.
