A compact triple‐band metamaterial‐inspired antenna for wearable applications

A low‐profile (28 mm × 32 mm × 0.394 mm), metamaterial‐inspired antenna employing an array of 3 × 5 Hilbert‐shaped unit radiators printed on the upper side of a flexible dielectric substrate while the lower side contains a partial‐ground plane and the rest consists of a periodic square‐slotted ground plane is presented for wearable wireless devices covering Long‐Term Evolution (LTE), Long Term Evolution‐Advanced (LTE‐A), Wireless Local Area Network (WLAN), and Worldwide Interoperability for Microwave Access (WiMAX) bands. The antenna provides steerable radiation patterns for frequencies ranging from 3.3 to 3.9 GHz and a directive end‐fire radiation in the 5.8 GHz band. At 2.45 GHz, the antenna allows short‐range communications between a wearable sensor and handheld wireless device or a nearby base station. Two prototypes are fabricated; the first using traditional wet etching with copper; the second using inkjet printing with silver nano‐particles (SNPs) as the conducting material. We provide a systematic design procedure and a new physical insight into the operation of the antenna, in particular the end‐fire radiation patterns, which is based on the anisotropic dispersion characteristics of the radiating structure along the length axis leading to different effective electrical length to width ratios within the stopband. The realized gain varies from 0 to 2.5 dBi for frequencies ranging from 3.3 to 3.9 GHz where the 3‐dB beamwidth varies from 110° to 140° and the boresight is steered from 0° to 80°. The maximum realized gain varies from 4.75 to 4.5 dBi over the frequency range from 4.4 to 6 GHz, with slight change in the beamwidth and main lobe direction. Experimental measurements for the SNP prototype are reported in air and on a standard phantom model.
Narcolepsy in children

Narcolepsy is a life-long but non-progressive neurological disorder characterized by excessive daytime sleepiness and increased presence of rapid eye movement (REM) sleep due to loss of hypocretin containing neurons located in the lateral hypothalamus. According to the International Classification of Sleep Disorders, Third Edition (ICSD-3), narcolepsy is typically associated with cataplexy and/or other REM sleep phenomena such as hypnagogic or hypnopompic hallucinations and sleep paralysis. Narcolepsy is not an uncommon disorder, but is under-recognized. The age of onset shows two peaks of presentation: in childhood and in adults. Both genetics and environmental factors may be involved in the development of narcolepsy. The history, combined with polysomnography and MSLT, remain the current gold standard in the diagnosis of narcolepsy. The levels of Hypocretin-1 are undetectable in the cerebrospinal fluid in most patients with narcolepsy with cataplexy. Early recognition and treatment can greatly improve the quality of life of patients with narcolepsy. Treatment of narcolepsy includes non-pharmacological treatment (life style changes) and pharmacological (stimulants, modafinil, sodium oxybate) against hypersomnia and anticataplectic drugs (antidepressants and sodium oxybate).
Metformin is Probably A New Option in the Treatment of Endometrial Cancer

Endometrial cancer (EC) is a common gynecological malignancy in western countries. Besides excessive estrogen exposure, many other risk factors have been observed, such as obesity, type II diabetes mellitus and polycystic ovary syndrome. To date, surgery remains to be the major treatment for endometrial cancer. However, surgical treatment seems to be unsuitable to some patients. Moreover, none effective method has been provided to prevent this malignancy. On the other hand, insulin resistance was suggested to play an important role in the development of endometrial cancer according to previous studies. Metformin is a common insulin-sensitizing agent used in the treatment of type II diabetes mellitus. The antitumor effects of this old drug have been increasingly reported in recent years. We propose that metformin will block the development of EC through different ways. Therefore, studying the mechanisms of metformin will provide us novel insights on both preventative and therapeutic medical strategies of endometrial cancer.
Distortions in sensitivity of carotid baroreceptor reflexes in rabbits following consumption of two forms of palm oil diets.

Aim: Long term consumption of dietary oils has been implicated in the etiology of hypertension. This study seeks to compare the effects of long term consumption of fresh palm oil (FPO) and thermoxidized palm oil (TPO) on baroreceptor reflex sensitivity (BRS), which is responsible for short term regulation of blood pressure. Methodology: The design of this study involved the use of eighteen, male, five month old New Zealand rabbits weighing 750 – 1000 g. They were divided into three groups (n = 6) as follows; control group (received normal animal feed only), FPO diet – fed group (received animal feed mixed with fresh palm oil in the ratio 85:15, respectively) and TPO diet – fed group (received animal feed mixed with thermoxidised palm oil in the ratio 85:15, respectively). The animals were fed for 6 months, after which they were used for the various experiments. Results: Mean daily food and water intake in FPO and TPO fed groups was significantly (p<0.001) lower compared with control. Heart rate for FPO group was significantly higher than the control Original Research Article Ani et al.; BJMMR, 8(3): 245-255, 2015; Article no.BJMMR. 2015.445 246 (p<0.001) and TPO (p<0.01) group. Basal systolic and diastolic blood pressures were significantly higher in TPO group than in the FPO and control (p<0.05) group. The FPO group also had a significantly lower basal systolic (p<0.01) and diastolic pressure (p<0.001) than the control group. The basal pulse pressure was significantly lower in the FPO group than the control (p<0.001) and the TPO group (p<0.01). The mean arterial pressure (MAP) for TPO group was significantly higher (p<0.001) than that of control and FPO groups. The baroreflex sensitivity for FPO group was significantly reduced compared with control (p<0.01) and TPO group (p<0.05). The TPO group showed a significantly lower (p<0.01) baroreflex sensitivity, compared with control. Conclusion: This study observed that chronic consumption of both fresh and thermoxidised palm oil diets caused a significant reduction in carotid baroreceptor reflex sensitivity. However, reduction in BRS was more in fresh palm oil – diet fed group, than the thermally oxidized palm oil diet – fed.
Classification of Genetically Identical Left and Right Irises Using a Convolutional Neural Network

As one of the most reliable biometric identification techniques, iris recognition has focused on the differences in iris textures without considering the similarities. In this work, we investigate the correlation between the left and right irises of an individual using a VGG16 convolutional neural network. Experimental results with two independent iris datasets show that a remarkably high classification accuracy of larger than 94% can be achieved when identifying if two irises (left and right) are from the same or different individuals. This exciting finding suggests that the similarities between genetically identical irises that are indistinguishable using traditional Daugman’s approaches can be detected by deep learning. We expect this work will shed light on further studies on the correlation between irises and/or other biometric identifiers of genetically identical or related individuals, which would find potential applications in criminal investigations.

Wideband Tomographic Super-Resolution Radar Image

Three-dimensional radar tomography exploits geometric and spatial diversity to reconstruct three-dimensional images. As the bandwidth is independent from the resolution of the tomographic radar imagery, we are proposing a novel method to increase the resolution with more detected features at less computational cost. In this method, we detect a plurality of frequencies of a target and generate a low-resolution image for each frequency with a first-order Born approximation, maintaining the linearity of the inverse problem. Additionally, a high-frequency low-resolution image will be selected as a reference image from the plurality of low-resolution images. Further, we obtain the pixel values of the reference image and compare them to each of the low-resolution images. The method will also include determining new features in each low-resolution image based on the comparisons, generating a high-resolution grid based on the new features identified by the comparisons via interpolation, performing deconvolution of the high-resolution grid using a Wiener filter, and outputting a high-resolution image.
Miniaturized DC–60 GHz RF PCM GeTe-Based Monolithically Integrated Redundancy Switch Matrix Using T-Type Switching Unit Cells

This article presents an approach to monolithically implement radio-frequency (RF) phase change material (PCM) germanium telluride (GeTe) T-type switch as a switching unit cell for millimeter-wave (mmWave) redundancy switch matrix applications. The miniature T-type switch demonstrates three states of operation, including one crossover state and two turn states. A seven-layer microfabrication process, including an additional conductive layer to reduce the <inline-formula> <tex-math notation="LaTeX">$RC$ </tex-math></inline-formula> time constant due to the bias network routing, is developed and optimized to fabricate the multiport RF devices. A <inline-formula> <tex-math notation="LaTeX">$4 \times 6$ </tex-math></inline-formula> PCM-based redundancy switch matrix is developed by monolithically integrating four T-type switches in the cascade configuration. Thermal crosstalk in PCM switches is experimentally investigated using submicrometer spatial resolution transient thermal imaging. The presented T-type switch has the device periphery of 0.55 mm <inline-formula> <tex-math notation="LaTeX">$\times \,\,0.55$ </tex-math></inline-formula> mm, while the overall integrated PCM redundancy switch matrix is fabricated with a device footprint of 0.88 mm <inline-formula> <tex-math notation="LaTeX">$\times \,\,1.1$ </tex-math></inline-formula> mm. The measured results of the T-type switches demonstrate an excellent RF performance with lower than 1.6 dB insertion loss, better than 20 dB return loss, and higher than 20 dB isolation in all states from dc–67 GHz. The redundancy switch matrix exhibits an insertion loss less than 3 dB, return loss better than 14 dB, and isolation higher than 20 dB from dc–60 GHz. To the best of our knowledge, this is the first implementation of a PCM-based redundancy switch matrix.
CLINICAL STUDY REGARDING PREEMPTIVE ANALGESIC EFFECT OF KETAMINE AND REMIFENTANYL IN LAPAROSCOPIC CHOLECYSTECTOMY

Pain modulation is related to an equilibrium between antinociceptive and pronociceptive systems. Therefore, the apparent pain level could not only be a consequence of a nociceptive input increase but could also result from a pain sensitization process. Glutamate, via N-Methyl ‐D-aspartate (NMDA) receptors, plays a major role in the development of such a neuronal plasticity in the central nervous system, leading to a pain hypersensitivity that could facilitate chronic pain development. By acting on both NMDA and opioid receptors we can get analgesic effect and prevent chronic pain development. According to these aspects, a clinical study estimating preemptive analgesia with ketamine and remifentanyl in laparoscopic cholecystectomy was designed and carried out. A number of 112 patients divided in five groups were analysed regarding efficiency and safety aspects. All the patients received the same dose of remifentanyl and different doses of ketamine. The results of the study indicated the best analgesic effect within the group in which the patients received 0.75 µg/kg/min remifentanyl from induction of anaesthesia until suture and ketamine was given in doses of 10 µg/kg/min from induction of anaesthesia and six hours in the postoperative period. Concerning the safety aspect of this scheme the result was less satisfying. Rezumat Modularea durerii reprezintă un echilibru intre sistemele antinociceptive si cele pronociceptive. Cresterea intensităţii durerii nu este doar consecinţa impulsurilor nociceptive, este si consecinţa sensibilizării centrale. Glutamatul, prin receptorii săi NMetil-D-aspartat (NMDA), joacă un rol important in dezvoltarea plasticităţii neuronale conducând la hipersensibilizare centrală cu instalarea durerii cronice. Receptorii NMDA precum si receptorii opioizi modulează efectul analgezic si reduc sensibilizarea centrală, ceea ce previne instalarea durerii cronice. Pornind de la aceste premize, am iniţiat si desfăsurat un studiu clinic de evaluare a analgeziei preemptive cu ketamină si remifentanil, in colecistectomiile laparoscopice. Am urmărit eficienţa si siguranţa, la 112 pacienţi repartizaţi in cinci grupuri, diferenţiate prin alternativele de inducere a analgeziei preemptive. Rezultatele studiului au evidenţiat ca
Identifi cation of differential genetic profi les in severe forms of fi bromyalgia and chronic fatigue syndrome/myalgic encephalomyelitis: a population-based genetic association study

Background : Fibromyalgia (FM) and chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) are believed to be two separate illnesses that are diagnosed using separate but overlapping clinical criteria; to date there are no biological markers for either condition. The symptoms of both disorders can differ markedly in presentation, frequency and intensity and therefore it is necessary to distinguish between the subtypes. Since recent studies have begun to determine the genetic background of these diseases, the authors suggest the use of single nucleotide polymorphism (SNP) analysis to investigate their different
Optimal Control of Building HVAC Systems in the Presence of Imperfect Predictions - eScholarship

This paper deals with the problem of robust model predictive control of an uncertain linearized model of a building envelope and HVAC system. Uncertainty of the model is due to the imperfect predictions of internal and external heat gains of the building. The Open-Loop prediction formulation of the Robust Model Predictive Control (OL-RMPC) is known to be unnecessarily over-conservative in practice. Therefore, we adopt a Closed-Loop prediction formulation of Robust Model Predictive Control (CL-RMPC) which exploits an uncertainty feedback parameterization of the control sequence and results in a tractable formulation of the problem. To improve on the efficiency of CLRMPC we propose a new uncertainty feedback parameterization of the control input, which leads to a number of decision variables linear in time horizon as opposed to quadratic as in previous approaches. To assess our approach we compare three different robust optimal control strategies: nominal MPC which does not have a priori information of the uncertainty, OL-RMPC and CL-RMPC. We show results from a quantitative analysis of performance of these controllers at different prediction error values of the disturbance. Simulations show that CL-RMPC provides a higher level of comfort with respect to OL-RMPC while consuming 36% less energy. Moreover, CL-RMPC maintains perfect comfort level for up to 75% error in the disturbance prediction. Finally, the newly proposed parameterization maintains the performance of CL-RMPC while reducing the simulation time by an average of 30%.
Editorial: The Role of Neutraceuticals in the Prevention & Treatment of Metabolic Syndrome

It has been close to a century since the constellation of clinical symptoms associated with the risk factors for diabetes, cardiovascular disease, cerebrovascular disease and renal disease have been identified. Initially observed and reported in the 1920s; however, the term metabolic syndrome was not universally utilized until the late 1970s. In 1947, observations by French physician, Dr. Jean Vague noticed that obesity was also associated with diabetes, atherosclerosis, renal lithiasis and gout. Conversely, Dr. Avogaro Crepaldi reported that several obese patients saw improvement in their diabetes, lipids and blood pressure when they followed a low-calorie and low carbohydrate diet.
Grammar-based map parsing for view invariant map descriptor

Map retrieval, the problem of similarity search over a large collection of 2D pointset maps previously built by mobile robots, is crucial for autonomous navigation in indoor and outdoor environments. Bag-of-words (BoW) methods constitute a popular approach to map retrieval; however, these methods have extremely limited descriptive ability because they ignore the spatial layout information of the local features. The main contribution of this paper is an extension of the bag-of-words map retrieval method to enable the use of spatial information from local features. Our strategy is to explicitly model a unique viewpoint of an input local map; the pose of the local feature is defined with respect to this unique viewpoint, and can be viewed as an additional invariant feature for discriminative map retrieval. Specifically, we wish to determine a unique viewpoint that is invariant to moving objects, clutter, occlusions, and actual viewpoints. Hence, we perform scene parsing to analyze the scene structure, and consider the “center” of the scene structure to be the unique viewpoint. Our scene parsing is based on a Manhattan world grammar that imposes a quasi-Manhattan world constraint to enable the robust detection of a scene structure that is invariant to clutter and moving objects. Experimental results using the publicly available radish dataset validate the efficacy of the proposed approach.
Lab-to-Genesis

We show that existing laboratory experiments have the potential to unveil the origin of matter by probing leptogenesis in the type-I seesaw model with three right-handed neutrinos and Majorana masses in the GeV range. The baryon asymmetry is generated by CP-violating flavour oscillations during the production of the right-handed neutrinos. In contrast to the case with only two righthanded neutrinos, no degeneracy in the Majorana masses is required. The right-handed neutrinos can be found in meson decays at BELLE II and LHCb.

A STUDY ON FEASIBILITY OF PROBLEM BASED LEARNING AT UNIVERSITY LEVEL

The study was designed to investigate the perceptions of university teachers for feasibility of problem based learning at university level. Being a descriptive study a questionnaire was used as a tool to acquire perceptions of university teachers regarding feasibility of problem based learning at university level. A purposive sample of 23 university teachers from two departments i.e. Education & Mass communication at university was selected including some senior faculty members. Participants were with different qualifications which ranged from masters to MS/PhDs. Data was analyzed through descriptive statistics and by calculating a t-test to determine the difference of perceptions among university teachers in view of their gender. Results indicated a strong perception of university teachers about effectiveness of problem based learning on student. It was also found that university teachers were having strong perceptions about initiation of problem based learning at university level. There was no significant difference about perceptions of teachers in view of their gender. Necessary changes in curriculum, assessment procedures, training of staff, administrative needs and raising of funding resources were recommended for initiation of problem based learning at university campus.
状態推定器を用いたロボットマニピュレータのロバスト軌道追従制御(機械力学,計測,自動制御)

In this paper a robust tracking control scheme without using adaptation and joint angular velocity measurements based on a state observer. The configuration of developed robust controller becomes very simple compared with that of regressor based adaptive controllers. It is shown that the Euclid norm of tracking errors can be arbitrarily reduced by using only one design parameter. Especially for a constant ideal trajectories, it is shown that Euclid norm of tracking errors converges to zero. Moreover, in the presence of quantization error in joint angle measurements, it is shown by numerical simulations and experiments that the proposed controller is more effective compared with the controller using Eular approximation of joint velocity.
Everolimus for subependymal giant-cell astrocytomas (SEGAs) in tuberous sclerosis (TS).

2004 Background: TS is a potentially devastating disorder characterized by hamartoma formation in multiple organ systems. SEGAs develop in 5-15% of TS patients and represent a significant medical risk, including the potential for sudden death secondary to acute hydrocephalus (as a result of their location adjacent to the foramen of Monro). Neurosurgical resection is the current standard treatment and no effective alternative has been identified. Methods: Patients ≥3 years with a definitive TS diagnosis and evidence of serial SEGA growth (on MRI) were eligible for this prospective, open-label, phase II study. The primary efficacy endpoint was change in SEGA volume from baseline to 6 months (mo). Everolimus dose (3 mg/m2 QD orally) was titrated subject to tolerability to achieve target trough concentrations of 5-15 ng/mL. Results: 28 patients were enrolled between 1/07 and 12/08; median duration of treatment was 22 mo (range 5-34). Everolimus was associated with a clinically meaningful reduction in SEGA vol.
