Design of a Compact Dual Band-Notched UWBAntenna

- This paper presents a compact microstrip-fed U-shape ultra-wideband antenna with dual band-notched characteristics. The proposed antenna covers the wide range of bandwidth over the frequency band from 2.75-11 GHz, having S11 < -10 dB, except WiMax (3.3-3.7 GHz) and C-band (3.7-4.2 GHz) notched frequency bands. The notched bands are achieved by introducing a pair of L-shaped slots on the radiating patch. Surface current distributions are used to analyze the slots effects and notched mechanism. The performance of this antenna by simulation indicates that theantenna is good candidate for UWB applications.
INSIDER DATA THEFT PREVENTION USING BEHAVIOR PROFILING

–In the commercial organizations especially small and medium scale businesses a lot depends on outsourcing of data which comes with more risk for insider data theft attacks. Insider data theft detection is an emerging field developed with opportunities for new research methodologies. Insider data theft attacks are caused by masquerader stealing a valid user's identification and using it to mimic the authenticate user. We present a novel anomaly detection approach where behavior profiling will be done by combining different classifier to build a sustainable ecosystem that can mitigate frauds efficiently. The system creates standard user behavior model by extracting features of user activity. Current user behavior is compared with the standard user behavior model of that user. If difference is observed then it will be considered as possibility of malicious activity. Ensemble of classifier is produced using Naïve Bayes Classifier and One-class support vector machine (SVM). The implemented system prevents unauthorized and illegitimate access to the system and provides security to the user’s data by profiling user’s behavior.
A variable-impedance piezoelectric tactile sensor with tunable sensing performance for tissue hardness sensing in robotic tumor palpation

This paper presents a novel piezoelectric tactile sensor for tissue hardness sensing, featuring online tunable sensing performance (resonant frequency, sensitivity, measurement range) through varying its mechanical impedance. The variable-impedance mechanism is achieved with a unique double-cantilever structure, which also enables the sensor to operate at a low frequency suitable for testing biological tissues. A simultaneous actuation and sensing technique is used which allows detecting resonant frequency from electrical impedance of the piezoelectric actuator without using additional motion sensors, therefore simplifies the sensor’s structure and instrumentation. The basic working principle and the variable-impedance method for performance tuning are explained mathematically and verified by numerical and experimental studies. The test results on a prototype show that it has an operating frequency (<300 Hz) much better than those in the literature. With the variable-impedance mechanism, sensitivity improvement ratios of 1.7, 2.6 and 3.8 times are achieved in three test ranges. And measurement range improvement ratio of 6.2 times is achieved. Ex vivo experiment confirms its effectiveness in detecting embedded lump. The proposed sensor can find wide applications in robotics, biomedical engineering, aerospace, etc, and may eventually inspire the designs of a new class of tactile sensors with online performance tuning capability.
Adaptive control of redundant robot manipulators with null-space compliance

Purpose The purpose of this paper is to propose an adaptive control for a redundant robot manipulator interacting physically with the environment, especially with the existence of humans, on its body. Design/methodology/approach The redundant properties of the robot manipulator are used and a reference velocity variable is introduced to unify the operation-space tracking control and the null-space impedance control under one common framework. Neural networks are constructed to deal with unstructured and unmodeled dynamic nonlinearities. Lyapunov function is used during the course of control design and simulation studies are carried out to further illustrate the effectiveness of the proposed strategies. Findings Satisfying tracking performance in the operation-space and compliance behavior in the null-space of the redundant robot manipulator are ensured simultaneously. Originality/value The design procedure of redundant robot manipulators control can be greatly simplified, and the framework of multi-priority control can be transformed into a joint-space velocity tracking problem via the introducing of a reference velocity variable.
UNIVERSAL DESIGN FRAMEWORK FOR THE DEVELOPMENT OF ADAPTABLE ARCHITECTURAL STUDIOS FOR LEARNING ENVIRONMENTS

Issues arising from the general problem of the inaccessibility of the built environment to people with disabilities (PWDs), have led to a paradigm shift from design approaches aimed at narrow code compliance, to design ideologies aimed at producing usable facilities and environments to meet the needs of everyone, particularly PWDs. One of such approaches is Universal Design (UD), a framework for designing products, buildings, and environments to be accessible and usable by everyone. Consequently, guidelines have been developed for many products and environments, including learning environments, in line with the UD principles. However, these models are considered inadequate to fully address design requirements of architectural studios in learning environments. This study developed a design framework for developing adaptable architectural studios, in line with UD parameters and peculiar needs of students in a traditional and digital studio learning environment. The study adopted a qualitative research approach. Observation and systematic review of relevant literature were used to collect data, which were coded according to themes for easy analysis for the development of the framework. Illustrations were employed to present the findings for clarity and easy understanding. The study outcome is a useful design guide for architects, an education material for teachers and students, and a UD repository reference material for researchers to work with and build upon as we work towards making our world more accessible and usable to all.
Segmentation and study of anatomical variability of the cochlea from medical images

Cochlear implants (CI) are used to treat hearing loss by surgically inserting an electrode array into the organ of hearing, the cochlea. Pre- and post-operative CT images are used routinely for surgery planning and evaluation of cochlear implantation. However, due to the small size and the complex topology of the cochlea, the anatomical information that can be extracted from the images is limited. The first focus of this work aims at defining automatic image processing methods adapted to the spiral shape of the cochlea to study the cochlear shape variability from high-resolution μCT images. The second focus aims at developing and evaluating a new parametric cochlear shape model. The model is applied to extract patient-specific clinically relevant metrics such as the maximal insertion depth of CI electrode arrays. Thanks to the uncertainty quantification, provided by the model, we can assess the reliability of CT-based segmentation as compared to the ground truth segmentation provided by μCT scans. Finally, the last focus concerns a joint model of the cochlear shape (and its substructures) model and its appearance within a generative probabilistic Bayesian framework. The proposed segmentation method was applied to a large database of 987 CT images and allowed the statistical characterization of the cochlear anatomical variability along with the quantification of the bilateral symmetry. This work paves the way to novel clinical applications such as improved diagnosis by identifying pathological cochlear shapes; preoperative optimal electrode design and insertion axis planning; postoperative electrode position estimation and implantation evaluation; and cochlear implantation simulation.
Planeación y despliegue de la red de sensores inalámbricos requerida para la medición inteligente de energía eléctrica usando restricciones de capacidad y cobertura

The electrical energy measurement (EEM), seeks to provide quality services without neglecting the reliability of the system. Therefore, a quality service must be closely linked to the wireless communication technologies, to technify the EEM, not only reading, but also cuts, reconnections, and other additional services that the intelligent measurement infrastructure provides through wireless technologies Such as cell or WiFi, increasingly common because of the reliability they provide in real-time data transmission. Wireless infrastructures allow us to provide coverage to the fixed terminals, determined by the electric meter, and in turn manage and plan the optimal deployment of wireless sensors (SI) in finite areas, whether urban, rural or suburban. This article proposes an optimal model for planning and deploying SI for the EEM in order to guarantee reliable wireless communication links at the lowest implementation cost. Therefore, the proposed algorithm gives global solutions within a finite scenario, making this a scalable model in time able to manage the use of available links. The SIs for the EEM are inserted into the Neighborhood Area Networks (NANs) covered by the mobile communications network.
C HANGES IN G ROWTH A ND P IGMENT C ONTENT IN S WEET P OTATO BY T RIADIMEFON A ND H EXACONAZOLE

SUMMARY Triadimefon and hexaconazole are triazole group of fungicides have plant growth regulating properties. The present investigation aimed to study the growth regulating effect of these compounds on sweet potato ( Ipomoea batatas L.). Each plant was treated with one litre of aqueous solutions containing 15mg L -1 triadimefon and 10mg L -1 hexaconazole on 40 and 70 days after planting (DAP) by soil drenching. The growth parameters of the plants were estimated on 45, 60, 75, 90 and 105 DAP. Among the triazole, hexaconazole inhibited the number of leaves, total leaf area, stem length, internodal length, leaf and stem dry weight, relative shoot growth rate significantly when compared to triadimefon. Triazole (chiefly available and plant control and yield production) treatments increase the root length, root and tuber dry weight, relative tuber growth rate, net assimilation rate root/shoot ratio, leaf dry weight per unit area, chlorophyll and carotenoid content.
Compact, Efficient, and Wideband Near-Field Resonant Parasitic Filtennas

As a hybrid component in RF front-end systems, filtennas possess the distinctive advantages of simultaneously combining filtering and radiating performance characteristics. Consequently, filtennas not only save space and costs but also reduce transmission losses. In this chapter, three sorts of filtennas have been proposed: the first sort is band-pass/band-stop filtennas, which are mainly realized by assembling band-pass/band-stop filters and antennas to achieve the combined functions; the second sort is multi-resonator-cascaded filtennas, which are obtained by altering the coupled-resonators in the last stage of the filters to act as the radiating elements; and the third sort is near-field resonant parasitic, bandwidth-enhanced filtennas, which are accomplished through organically combining radiator and filtering structures. For the second and third sorts, it is worth noting that the design methods witness significant electrical size reduction without degrading the radiation performance of the filtennas in general.
Effective Teaching Research in Chinese Educational Contexts: A General and Dimensional Review

Abstract Effective teaching is an important research topic worldwide. This review aims to analyze effective teaching literature in China with respect to general characteristics and conceptional dimensions. Two types of effective teaching literature, empirical studies written in Chinese and written in English, are selected for this review. Stronge’s effective teaching framework is adopted for examining the conceptual dimensions in the selected studies. The results taken from the two types of literature reveal different research orientations regarding effective teaching. The literature written in Chinese demonstrates a number of quantitative research studies that, overall, are ill-written from the standard criteria of empirical study writing, including serious design flaws, missing important information, and weak data interpretations. In contrast, the literature written in English tends to focus more on a qualitative research orientation with sufficient overall quality for methodological design. Regarding the effective teaching dimensions, the dimension of the Teacher as a Person is interpreted differently, while the dimension of Implementing Instruction is most often commonly adopted in the two types of literature. We suggest that more studies are needed to conceptualize effective teaching frameworks from macro, meso, and micro levels in order to enhance the quality of effective teaching research in China. Additionally, effective teaching studies related to minority students are rare and deserve future investigation.
GINGIVAL RECESSION IN DISIMPACTED CANINES - A RETROSPECTIVE STUDY

: Multidisciplinary management is essential when the canine fails to erupt on time. This requires combined surgical and orthodontic intervention. Good periodontal status is necessary for the positive outcome of treatment. Hence the objective of this study was to evaluate the incidence of gingival recession in disimpacted canines. A retrospective study was conducted. Data collection was done through reviewing 86000 patients who had visited a hospital in Chennai from June(2019) to March(2020). A total of 6 patients who had undergone disimpaction of canine were evaluated. Data such as age, gender, site of impaction, presence of gingival recession were noted. The data was analysed statistically through IBM SPSS software. The study group belonged to the age group ranging 13-21. Disimpaction was performed higher among males(66.6%) compared to females. Among the samples, about 57.14% of canines were palatally impacted. No gingival recession was seen in the study sample. The incidence of gingival recession in the disimpacted canines was not statistically significant and did not reach clinical significance due to very less sample size.

Combination therapy in metastatic castration sensitive prostate cancer: A Systematic review and network meta-analysis

Introduction: Studies directly comparing the different combination therapies offered to men with metastatic castration sensitive prostate cancer (mCSPC), are not available yet. This study was designed using the network meta-analysis (NMA) framework to provide a comparison of the different available options for the treatment of men with mCSPC. Methods: A systematic search was performed and the prospective randomized controlled trials reporting the overall survival (OS) or failure-free survival (FFS) were selected for review. A total of 14 studies were included in the NMA. Results: The addition of abiraterone, apalutamide, docetaxel, and docetaxel with zoledronic acid to the androgen deprivation therapy (ADT) demonstrated a significant improvement in the OS. In indirect comparison, abiraterone had a higher impact on the OS as compared to docetaxel (hazard ratio [HR]: 1.21, 95% confidence interval [CI]: 1.0–1.46) and docetaxel with zoledronic acid (HR: 1.31, 95% CI: 1.05–1.63) but not apalutamide. Furthermore, apalutamide was not different than docetaxel or docetaxel with zoledronic acid. There was a significant improvement in the FFS with the combination of abiraterone, apalutamide, docetaxel (HR: 0.61, 95% CI: 0.46–0.81), docetaxel with zoledronic acid (HR: 0.62, 95% CI: 0.43–0.9), and enzalutamide (HR: 0.39, 95% CI: 0.25–0.61) as compared to the ADT alone. Similar to the indirect comparison of OS, abiraterone outperformed docetaxel (HR: 1.66, 95% CI: 1.12–2.47), docetaxel with zoledronic acid (HR: 1.69, 95% CI: 1.06–2.68), and enzalutamide (HR: 1.06, 95% CI: 0.63–1.80), but not apalutamide in terms of impact on the FFS. Conclusion: Overall, abiraterone demonstrated better OS and FFS outcomes as compared to all the other combination strategies in this NMA.
2004 Thermodynamics of MHD ﬂows with axial symmetry

We present strategies based upon extremization principles, in the case of the axisymmetric equations of magnetohydrodynamics (MHD). We study the equilibrium shape by using a minimum energy principle under the constraints of the MHD axisymmetric equations. We also propose a numerical algorithm based on a maximum energy dissipation principle to compute in a consistent way the equilibrium states. Then, we develop the statistical mechanics of such ﬂows and recover the same equilibrium states giving a justiﬁcation of the minimum energy principle. We ﬁnd that ﬂuctuations obey a Gaussian shape and we make the link between the conservation of the Casimirs on the coarse-grained scale and the process of energy dissipation.
Large N field theory and AdS tachyons

: In non-supersymmetric orbifolds of N = 4 super Yang-Mills, conformal invariance is broken by the logarithmic running of double-trace operators — a leading eﬀect at large N . A tachyonic instability in AdS 5 has been proposed as the bulk dual of double-trace running. In this paper we make this correspondence more precise. By standard ﬁeld theory methods, we show that the double-trace beta function is quadratic in the coupling, to all orders in planar perturbation theory. Tuning the double-trace coupling to its (com-plex) ﬁxed point, we ﬁnd conformal dimensions of the form 2 ± i b ( λ ), as formally expected for operators dual to bulk scalars that violate the stability bound. We also show that conformal invariance is broken in perturbation theory if and only if dynamical symmetry breaking occurs. Our analysis is applicable to a general large N ﬁeld theory with vanishing single-trace beta functions.
OCCURRENCE OF ANTERIOR CRUCIATE LIGAMENT INJURIES IN FEMALE PLAYERS DURING SPORTS ACTIVITIES

The number of female participants in all level of sports has risen greatly in less developing countries in recent years. So, also has changed the way women play. Once slow and defensive style has now changed into speed, precision and power. However, studies in less developed countries show that these changes have led to increased injuries and female athletes have higher injury rates than men in many sports, particularly basketball, skiing, volleyball and apparatus gymnastics. Anterior Cruciate Ligament (ACL) injuries occur mostly commonly in sports such as basketball, soccer and volleyball. It is observed that female athletes injure the ACL more frequently than their male' counterparts do. The greater incidence of ACL injuries in women probably stem from complex interrelated factors, possibly including hamstring-quadriceps strength imbalances, joint laxity and the use of ankle braces. Successful treatment often includes surgery. Given these findings a review of the incidence and causes of these injuries among female players of basketball, soccer and volleyballs is in order. Such a review might suggest areas of further study that could help physicians treat ACL injuries more effectively in their female patients.
ANALYSIS OF GENE EXPRESSION PROFILING AND OVERLAPPING TRANSCRIPTIONAL PROFILES IN NONSPECIFIC INTERSTITIAL PNEUMONIA

: Introduction: Idiopathic pulmonary fibrosis, identified histologically as usual interstitial pneumonia, accounts for most cases of idiopathic interstitial pneumonia. IPF affects men and women > 50 in a ratio of 2:1, with a markedly increased incidence with each decade of age. Aims and objectives: The basic aim of the study is to analyze gene expression profiling and overlapping transcriptional profiles in non-specific interstitial pneumonia. Material and methods: This study was conducted at Children Hospital & Institute of Child Health, Multan with the collaboration of King Edward medical college, Lahore in June 2018 to August 2018. RNA was extracted and hybridized to the Human Gene 1.0 set array from explanted lungs (2001 – 2008) in 22 patients with clinical diagnosis of sporadic IPF. 10 subjects with clinical diagnosis of idiopathic NSIP and definite histologic pattern of fibrotic NSIP; and 11 normal lung samples (age 52 ± 18 years, 4 females) obtained from the region of normal tissue flanking lung cancer resections in ILD-free patients. Results: There were no significant differences in pulmonary function tests, exercise capacity or pulmonary artery pressures. NSIP patients were significantly younger than IPF patients. Genes with significantly increased expression in NSIP, compared to both IPF and normal controls, were involved in regulatory mechanisms of immune reaction, including the alloreactive T cell response. Conclusion: It is concluded that gene expression profiling from whole lung explants aligns separate, well-recognizable histopathologic patterns of IIP with distinct transcriptional profiles and differentially expressed genes, and the notion of NSIP as an early manifestation of IPF.
Finite element analysis of electroactive and magnetoactive coupled behaviors in multi-field origami structures

Active origami-inspired designs, which incorporate active materials such as electroactive polymers and magnetoactive elastomers into self-folding structures, have shown good promise in engineering applications. In this article, finite element analysis models are developed for several bending and folding configurations that incorporate a combination of active and passive material layers, such as electroactive polymer–actuated unimorph benders based on single and multilayer electroactive polymers, electroactive polymer–actuated notched unimorph folding configurations, and a multi-field actuated bimorph configuration. Constitutive relations are developed for both electrostrictive and magnetoactive materials to model the coupled behaviors explicitly. Shell elements are adopted for their capacity of modeling thin films, relatively low computational cost, and ability to model the intrinsic coupled behaviors in the active materials under consideration. The electrostrictive coefficients are measured and then used as input in the constitutive modeling of the coupled behavior. The magnetization of the magnetoactive elastomer is measured and then used to calculate the magnetic torque as a function of the special orientation, which leads to spatial deformation of the magnetoactive elastomers. The objective of the study is to validate the constitutive models implemented through the finite element analysis method to simulate multi-field coupled behaviors of the active origami configurations. Through quantitative comparisons, simulation results show good agreement with experimental data. By investigating the impact of material selection, location, and geometric parameters, this finite element analysis approach can be used in design of self-folding structures, reducing trial-and-error iterations in experiments.
