Magnetic quadrupole mode excitation of a cylindrical dielectric resonator antenna using planar feed

In this article, excitation of the magnetic quadrupole mode of a cylindrical dielectric resonator antenna, designated as the HEM21δ mode, using planar feeding technique is discussed for the first time. Two types of planar feeds—a dual‐microstrip feed and a dual‐slot feed are numerically investigated. Results show that the dual‐slot feed is more suitable for exciting the HEM21δ mode as it gives better symmetry of the radiation pattern and lower cross‐polarization level. A DRA prototype (dielectric constant, εr = 24, loss tangent, tanδ = 0.002, diameter, 2a = 19.43 mm and height, h = 7.3 mm) using dual‐slot feed is fabricated and characterized. Measurements demonstrate a resonant frequency of ~ 4.96 GHz, bandwidth of ~4.4%, peak gain of ~3.45 dBi and peak cross‐polar level of ~ − 11 dB for the HEM21δ mode, which are in decent agreement with numerical predictions.
TRANSITION FROM HYPERBOLICITY TO ELLIPTICITY FOR A p-SYSTEM WITH VISCOSITY

In this article we consider a viscous regularization of a p-system with a Van der Waals pressure law, which presents both hyperbolic and elliptic zones. Even if the purely hyperbolic Van der Walls system is strongly ill-posed, we prove that the solutions of the regularized equation exist and experience a transition from ellipticity to hyperbolicity, i.e. solutions issued from initial data in the elliptic zone will enter the hyperbolic zone at some time T > 0, and viceversa.
Calibration of a 3D laser rangefinder and a camera based on optimization solution

The calibration of a 3D laser rangefinder (LRF) and a camera is a key technique in the field of computer vision and intelligent robots. This paper proposes a new method for the calibration of a 3D LRF and a camera based on optimization solution. The calibration is achieved by freely moving a checkerboard pattern in front of the camera and the 3D LRF. The images and the 3D point clouds of the checkerboard pattern in various poses are collected by the camera and the 3D LRF respectively. By using the images, the intrinsic parameters and the poses of the checkerboard pattern are obtained. Then, two kinds of geometric constraints, line-to-plane constraints and plane-to-plane constraints, are constructed to solve the extrinsic parameters by linear optimization. Finally, the intrinsic and extrinsic parameters are further refined by global optimization, and are used to compute the geometric mapping relationship between the 3D LRF and the camera. The proposed calibration method is evaluated with both synthetic data and real data. The experimental results show that the proposed calibration method is accurate and robust to noise.
FRI0326 Incorporating patient reported outcome measures in clinical practice: development and validation of a proms questionnaire for sle

Background Rheumatology is embarking on a fundamental redesign of rheumatic disease care. It became mandatory not only to recognize disease activity core set data, but also the risks for other co-morbidities associated with the disease. Measurement of patient reported outcomes have become critical in both standard clinical practice and long term observational studies. Objectives to assess validity; reliability and responsiveness to change of a patient self-reported outcome measures (PROMs) questionnaire which can assess construct outcome measures of SLE patients. Methods The PROMs was conceptualized based on frameworks used by the WHO Quality of Life tool, as well as the PRO measurement information system (PROMIS). Cognitive interviews were conducted with 36 SLE patients (diagnosed according to ACR criteria), with a range of severity and disease activity to identify item pool of questions. Item selection and reduction was achieved based on patients as well as an interdisciplinary group of physicians, nurses, and health educators, in addition to clinometric and psychometric methods. The latter included Rasch and internal consistency reliability analyses. The questionnaire includes assessment for functional disability, quality of life, VAS for pain, global status, fatigue, duration of morning stiffness, SLE manifestations, lupus medications as well as review of the systems including the falls and cardiovascular risks, self-helplessness and self-reported joint pain. SLEDAI, SF-36 and Euro QoL 5D were assessed for every patient. Results The questionnaire was reliable as demonstrated by a high-standardized alpha (0.894-0.971). The questionnaire items correlated significantly (P< 0.01) with clinical parameters of disease activity. Patient reported tender joints correlated significantly with the physician’s scores (r= 0.842). Content construct assessment of the PROMs-functional disability and QoL revealed significant correlation (P< 0.01) with both SF-36 and Euro QoL respectively. Changes in parameters of disease activity, SLE systemic manifestations, functional disability, quality of life as well as self-helplessness scores showed significant (P< 0.01) variation with diseases activity status. Mean time to complete the PROMs was 7.01 + 0.92 min. The PROMs questionnaire showed also a high degree of comprehensibility (9.3). Conclusions Integrating patient reported outcome measures into standard clinical practice is feasible and applicable. This version of multidimensional SLE-PROMs questionnaire was found to be valid and reliable. It provides informative quantitative measure for the disease activity core set data, and in the meantime, facilitates assessing the patient’s disease activity, health related quality of life measure, cardiovascular and falls risks on individual basis.

Precise smart model for estimating dynamic viscosity of SiO2/ethylene glycol–water nanofluid

ABSTRACT Artificial neural network (ANN) is widely being used in engineering applications in order to provide predicting models to estimate the performance of the studied system under specific working conditions. One of the significant characteristics that are highly practical in fluid mechanics and heat transfer systems is the dynamic viscosity which highly affects pressure drop and also has an influence on the heat transfer performance. Due to the lack of a precise model to predict the dynamic viscosity, in this research, experimentally measured dynamic viscosity of SiO2/ethylene glycol–water nanofluid data is collected from the literature and used to present a smart model based on the ANN technique. In order to provide a precise smart model, Multilayer Perceptron (MLP) and Radial Basis Function (RBF) algorithms are applied in the neural network. The accuracy of the proposed model is validated through performing error analysis. It is monitored that the employed approach is highly potent in estimating high accuracy responses since the results of mean square and correlation coefficient analyses are 5.5 and 0.998 Pa s.
Zonotopic fault detection observer design for discrete‐time systems with adaptively adjusted event‐triggered mechanism

This study addresses the event-triggered fault detection for a class of discrete-time systems with unknown but bounded external disturbance and measurement noise. In order to save limited network bandwidth, an adaptively adjusted event-triggered scheme is designed by considering the probability of system failure and the fault detection progress. Based on the event-triggered system output, an H _ / L ∞ fault detection observer is well designed in finite frequency ranges, such that the generated residual is sensitive to injected faults and robust against disturbance and noise. Moreover, a novel zonotope-based residual evaluation strategy is constructed to reduce conservatism by considering the impacts of external disturbance, measurement noise and measured error caused by event-triggered scheme. Finally, simulation results are provided to demonstrate the effective performance of the proposed event-triggered fault detection strategy.
Low-RCS and Beam-Steerable Dipole Array Using Absorptive Frequency-Selective Reflection Structures

This communication presents an approach to design a beam-steerable dipole array with low radar cross section (RCS). A 2-D periodical array of dipole antennas is colocated with absorptive frequency-selective reflection (AFSR) structures to effectively reduce the out-of-band RCS and maintain high gain at the in-band frequencies. The AFSR structures consist of 3-D bandstop frequency-selective structure (FSS) and pyramidal-shaped absorbers to provide a reflection band for the dipole array with enhanced front-to-back ratio. Compared with the reference array, the radiation performance of the proposed array is maintained with an aperture efficiency of 70% and a measured peak gain of 21.5 dBi. The beam-steering angle is up to ±45°. Meanwhile, more than 10 dB two-sided out-of-band RCS reduction is achieved with a bandwidth of 96.5% and 30% for copolarization and 142% for cross polarization, and the in-band RCS is unchanged.
Genericity in Greek: An Experimental Investigation

Despite the abundance of semantic literature on genericity (Krifka et al. 1995), the cross-linguistic aspect of genericity has rarely been tackled systematically (see though Dahl, 1985; Behrens, 2000, Dayal, 2004). Moreover, there is very little experimental research on the topic in Greek. The aim of the present study is to collect native speakers’ judgments against the claims in the theoretical literature by extending Ionin et al.’s (2011) experimental approach to Greek. We present results of an online study with 40 adult native Greek speakers, who participated in an Acceptability Judgment Task with contexts testing canonical definiteness, as well as two distinct sources of genericity: (a) NP-level genericity with kind-level predicates like be extinct, as in (1), and (b) sentence-level genericity, as in (2). Our results largely confirm the predictions and support Dayal’s (2004) theoretical account of genericity: definite singulars were rated higher with NP-level genericity than with sentence-level genericity, definite plurals were rated equally high with both types of genericity, and indefinite singulars were rated higher with sentence-level than with NP-level genericity. The results will be further discussed in light of recent theories of genericity (Leslie 2008).
Arthroscopic Lateral Ankle Ligament Reconstruction

The modified Brostrom repair is currently the method of choice for the primary operative treatment of chronic lateral ankle instability. Before 2007, the investigators used the traditional open approach with or without the use of suture anchors. This study describes our current technique for arthroscopic lateral ankle ligament reconstruction, which has been continuously refined over the past several years. We believe that this novel technique simplifies the ligament reconstruction procedure when performed with ankle arthroscopy, potentially reduces operative time, and will produce results equivalent to the long-term outcome of the traditional open Brostrom procedure. Since November 2007, twenty-three patients (24 ankles) have undergone arthroscopic lateral ligament repair. All patients had positive ankle instability with manual stress testing and failed nonoperative management. Initially, only one suture anchor was used for the technique and now all cases are performed with 2 anchors. After an average follow-up of 10.9 months, all patients reported significant improvement compared with their preoperative symptoms. Four patients were noted to a have mildly positive residual stress test despite no functional limitations. One patient had persistent peroneal tendon symptoms necessitating exploration and debridement; and 1 developed an unrelated neurological process. We describe our technique for arthroscopic lateral ankle ligament reconstruction and preliminary results.

Compact design of two-elements cubic Yagi-Uda array antenna with high gain

A cubic Yagi-Uda array antenna with high gain for 500 MHz rectenna is proposed. The proposed antenna is composed of two elements of Yagi-Uda antenna. The proposed antenna is compact and its volume is λ/3× λ/3× λ/3 because the Yagi-Uda antennas share a reflector and director. Performance of the proposed antenna is demonstrated and resultant gain is as high as 8.5 dBi. Finally, the proposed antenna is applied to a 500 MHz rectenna system with voltage doubler rectifiers and its performance is demonstrated experimentally.
Adaptive Generation of Unrestricted Adversarial Inputs

Neural networks are vulnerable to adversarially-constructed perturbations of their inputs. Most research so far has considered perturbations of a fixed magnitude under some $l_p$ norm. Although studying these attacks is valuable, there has been increasing interest in the construction of (and robustness to) unrestricted attacks, which are not constrained to a small and rather artificial subset of all possible adversarial inputs. We introduce a novel algorithm for generating such unrestricted adversarial inputs which, unlike prior work, is adaptive: it is able to tune its attacks to the classifier being targeted. It also offers a 400-2,000x speedup over the existing state of the art. We demonstrate our approach by generating unrestricted adversarial inputs that fool classifiers robust to perturbation-based attacks. We also show that, by virtue of being adaptive and unrestricted, our attack is able to defeat adversarial training against it.

Experimental Results of Synchronous Reluctance Motors to Meet the IE4 Efficiency Standards in Variable Speed Applications

Regulation of the efficiency of electric motors worldwide has recently been tightened further because the contribution of electric motors to overall energy consumption cannot be denied. For many years, induction motors have fulfilled tasks in various fields of industry; however, alternative motors have also been gaining attention to realize more cost-effective motors over the long term. It is foreseen that induction motors (IMs) may not be replace-able in single-speed applications, excluding a few special applications; however, applications for which the variation of speed is required offers opportunities for the entry of other motor technologies. Synchronous reluctance motors (SynRMs) are one option that could provide such benefits. This paper provides the experimental results of SynRMs which, under the rated condition, aim to satisfy the IE4 efficiency class. Five SynRMs ranging in power through 5.5, 15, 37, 75 to 132 kW have been manufactured and tested for experimental comparison with IMs of equivalent output power.
Plasma and Tissue Pharmacokinetics of Cefazolin in an Immature Porcine Modelof Pediatric Cardiac Surgery

Background: Surgical Site Infection (SSI) prevention for children with congenital heart disease is imperative and methods to assess and evaluate the tissue concentrations of prophylactic antibiotics are important to help maximize these efforts. The purpose of this study was to determine the plasma and tissue concentrations of standard-of-care peri-operative cefazolin dosing in an immature porcine model of cardiac surgery and cardiopulmonary bypass. Methods: Piglets (3-5 days old) underwent either median sternotomy (MS) or cardiopulmonary bypass with deep hypothermic circulatory arrest (CPB+DHCA) and received standard of care prophylactic cefazolin for the procedures. Serial plasma and microdialysis sampling of skeletal muscle and subcutaneous tissue adjacent to the surgical site was performed. Cefazolin concentrations were measured, non-compartmental pharmacokinetic analyses were performed, and tissue penetration of cefazolin was assessed. Results: Following the first intravenous dose, maximal cefazolin concentrations for plasma and tissue samples were similar between groups with peak tissue concentrations 15-30 minutes after administration. After the second cefazolin dose given with initiation of CPB, total plasma cefazolin concentrations remained relatively constant until the end of DHCA and then decreased while muscle and subcutaneous unbound cefazolin concentrations showed a second peak during or after rewarming. For the MS group, 60-67% of the intraoperative time showed tissue cefazolin concentrations greater than16 μg/mL while this percentage was 78-79% for the CPB+DHCA group. There was less tissue penetration of cefazolin in the group that underwent CBP+DHCA (P=0.03). Conclusions: The cefazolin dosing used in this study achieves plasma and tissue concentrations that should be effective against methicillin-sensitive Staphylococcus aureus but may not be effective against some gram-negative pathogens. The timing of cefazolin administration prior to incision and a second dose given during cardiopulmonary bypass may be important factors for achieving goal tissue concentrations.
El esfínter esofágico inferior hipertenso. Prevalencia y características clinicomanométricas

SUMMARY Background: The hypertensive lower esophageal sphincter (HLES) is an unusual primary motor disorder of the esophagus. The lack of a precise definition has made it difficult to establish its prevalence and its clinical and manometric characteristics. Objectives: 1) To determine the prevalence of HLES using precise diagnostic criteria, 2) To identify the clinical manifestations of this disease, and 2) To compare manometric findings in patients with HLES against normal subjects. Methods: A total of 705 consecutive esophageal manometries were performed over 52 months. HLES was defined as basal pressure 45 ≥ mmHg, normal relaxation in response to swallowing, and normal peristalsis of the esophageal body. Clinical records were reviewed to identify the main symptoms that prompted the manometry. The manometric data of patients with HLES was compared to that of 16 healthy control subjects. Results: Seven HLES patients were identified establishing a prevalence of 1%. Four HLES cases were referred due to dysphagia, two due to symptoms of gastroesophag eal reflux disease, and one due to thoracic pain. Upon comparing manometric data of patients with HLES and healthy control subjects the motor function of the esophageal body, the total length of the lower esophageal sphincter, and its position in respect to the diaphragm were similar in both groups. Conclusions: Prevalence of HLES was 1%. Dysphagia was the main symptom. Total length of the sphincter, as well as length of the thoracic and abdominal segments do not appear to contribute to high basal pressure.
On the spectral theory for first-order systems without the unique continuation property

We consider the differential equation on the real interval when J is a constant, invertible skew-Hermitian matrix and q and w are matrices whose entries are distributions of order zero with q Hermitian and w non-negative. In this situation, it may happen that there is no existence and uniqueness theorem for balanced solutions of a given initial value problem. We describe the set of solutions the equation does have and establish that the adjoint of the minimal operator is still the maximal operator, even though unique continuation of balanced solutions fails.
Ventriculitis: A Case of Cerebral Toxoplasmosis in Immunocompetent Child

Cerebral toxoplasmosis is the most important opportunistic infection in patients with acquired immunodeficiency syndrome. However, it is a rare finding in immunocompetent persons. The patient was a 14-year-old boy who presented with headache and vertigo. Toxoplasma serology revealed raised IgG antibody level. No primary or secondary immune deficiency was found. Radiologic examination revealed ventriculitis. Microscopically, the lesion consisted of reactive gliosis and calcification. After antitoxoplasma treatment, the patient condition improved. Brain toxoplasmosis usually presented as periventricular/basal ganglial lesions. We report a case of a child patient with an atypical pattern of toxoplasma encephalitis, presenting
