Simple prediction of FSS radome transmission characteristics using an FSS equivalent circuit model

We propose a simple method for predicting the characteristics of Frequency Selective Surface (FSS) radome using an equivalent circuit model. The required material properties, such as the permittivity and permeability of the FSS, were extracted from a FSS equivalent circuit model using a transmission and reflection method. These parameters were then used to calculate the transmission characteristics of FSS radome. We designed a sandwich radome using a square loop FSS for a 23GHz band application. In order to demonstrate the validity of our approach, we also performed a simulation to obtain the characteristics of the FSS radome using commercial full-wave software. The results from the two approaches are in good agreement. The method proposed herein could be used for the simple and rapid calculation of the design and fabrication of a FSS radome. The FSS radome is that a square loop FSS that has a stop band at 23GHz is insulated between two dielectric materials. A simple analysis of a FSS radome requires the material constants, the permittivity and permeability of the square loop FSS, which we extracted using transmission/reflection. Using the material constants derived from a FSS equivalent circuit model, the characteristics of the FSS radome were calculated for a simple 2-D case. The results were verified using a commercial full-wave three-dimensional electromagnetic wave simulator. The resulting characteristics of the FSS radome agreed with those obtained using a full-wave simulation. We show herein that the characteristics of a FSS radome can be analyzed and predicted with relative ease using an approximate FSS to achieve a simple 2-D construction. Our method can be applied to the analysis of FSS radome for use with various communication systems and electrical instruments.
Diagnosis and Management of Bronchiolitis

Bronchiolitis is a disorder most commonly caused in infants by viral lower respiratory tract infection. It is the most common lower respiratory infection in this age group. It is characterized by acute inflammation, edema, and necrosis of epithelial cells lining small airways, increased mucus production, and bronchospasm. The American Academy of Pediatrics convened a committee composed of primary care physicians and specialists in the fields of pulmonology, infectious disease, emergency medicine, epidemiology, and medical informatics. The committee partnered with the Agency for Healthcare Research and Quality and the RTI International-University of North Carolina Evidence-Based Practice Center to develop a comprehensive review of the evidence-based literature related to the diagnosis, management, and prevention of bronchiolitis. The resulting evidence report and other sources of data were used to formulate clinical practice guideline recommendations. This guideline addresses the diagnosis of bronchiolitis as well as various therapeutic interventions including bronchodilators, corticosteroids, antiviral and antibacterial agents, hydration, chest physiotherapy, and oxygen. Recommendations are made for prevention of respiratory syncytial virus infection with palivizumab and the control of nosocomial spread of infection. Decisions were made on the basis of a systematic grading of the quality of evidence and strength of recommendation. The clinical practice guideline underwent comprehensive peer review before it was approved by the American Academy of Pediatrics. This clinical practice guideline is not intended as a sole source of guidance in the management of children with bronchiolitis. Rather, it is intended to assist clinicians in decision-making. It is not intended to replace clinical judgment or establish a protocol for the care of all children with this condition. These recommendations may not provide the only appropriate approach to the management of children with bronchiolitis.
Image-guided procedures for intensity-modulated spinal radiosurgery

✓ Radiosurgery for brain tumors has been well established in the radiation oncology and neurosurgery fields. Radiosurgery of extracranial tumors such as those involving the spine is, however, still in the early stage because of difficulties in patient immobilization and organ motion. The authors describe an image-guided procedure for intensity-modulated spinal radiosurgery that was developed at Henry Ford Hospital.
Compact LTCC source-load coupled SIW filter using mixed coupling

A novel substrate integrated waveguide (SIW) filter with source-load coupling based on low temperature co-fired ceramic (LTCC) technology is proposed. By introducing mixed coupling into input/ output SIW in middle layer, the filter not only has good selectivity owing to the controllable transmission zeros, but also has a compact size by the virtue of LTCC structure. Based on the flexible coupling manner in multilayer structure, a demonstration second-order bandpass filter with three transmission zeros has been designed and fabricated. Good agreement between measured and simulated results is observed.
Distinct roles of ligand affinity and cytoskeletal anchorage in αIIbβ3 (GP IIb/IIIa)-mediated cell aggregation and adhesion

Platelet integrin αIIbβ3 (GP IIb/IIIa) is functionally modulated by changes in ligand affinity or in cytoskeletal anchorage. CHO cells transfected with wild-type/mutated αIIbβ3 allow the dissection of the relative contributions of the two regulatory mechanisms in αIIbβ3-mediated adhesion and aggregation. Mutations included a truncation of the cytoplasmic domain of the β-subunit, resulting in a loss of cytoskeletal anchorage of αIIbβ3, and a VGFFK-deletion of the α-subunit, resulting in a permanent high affinity state. αIIbβ3-mediated cell aggregation is dependent on the high affinity state but only partially on the cytoskeletal anchorage of αIIbβ3. In contrast, αIIbβ3-mediated cell adhesion is dependent on the cytoskeletal anchorage but only partially on the high affinity state of αIIbβ3. Thus, the functional evaluation of mutated αIIbβ3 implies a differential role of affinity state and cytoskeletal anchorage for αIIbβ3-mediated cell adhesion and aggregation.
Enhancement of the immune responses to ovalbumin in mice by oral administration of the extract from Radix cyathulae (RC)

This study was designed to evaluate the effects of oral administration of the extract from theRadix cyathula (RC) on the immune responses in mice immunized with ovalbumin (OVA). Forty-two Institute of Cancer Research (ICR) mice were randomly divided into six groups with seven animals in each group, and orally administered daily for 4 days at a dose equivalent to 0, 0.05, 0.1, 0.2, 0.4 and 0.8 g of the RC extract, respectively. After that, the mice were subcutaneously immunized twice with OVA at 2 weeks intervals. On day 14 after the second immunization, OVA-speciﬁc Immunoglobulin G (IgG) and the IgG subclasses, lymphocyte proliferation response, as well as interleukin-4 (IL-4) and interferon-gamma(IFN-γ) production were measured. Results indicated that the optical density (OD) value of OVA-speciﬁc IgG and the IgG subclass were signiﬁcantly enhanced in mice orally administered RC at the dose of 0.2, 0.4 or 0.8 g, compared to the control group (p < 0.05). Besides, the splenocytes proliferation response and the production of IL-4 and IFN-γ were also signiﬁcantly improved (p < 0.05) after the splenocytes were stimulated by OVA. In addition, the body weight of the mice administered with the RC extract (0, 0.1, 0.2, 0.4 and 0.8 g) was not signiﬁcantly different compared to the mice administered saline. Collectively, the data suggested that RC extract could improve the immune response of vaccine through up-regulating the humoral immune response and the cellular immune response. Key words: Radix cyathula, ovalbumin, adjuvant.
Resistência do Mycobacterium tuberculosis às drogas em pacientes HIV+ em cinco municípios da Baixada Santista, São Paulo, Brasil

Since the early 1990s, an increase in Mycobacterium tuberculosis drug resistance has been reported, with high prevalence among HIV+ patients. We evaluated the sensitivity patterns of M. tuberculosis, resistance rate, and predisposing factors among HIV+ patients in Santos, Sao Vicente, Cubatao, Praia Grande, and Guaruja, Sao Paulo State, Brazil. The medical charts of 301 patients with positive cultures for M. tuberculosis from 1993 to 2003 were reviewed. Resistance occurred in 57 patients (18.9%), as follows: 32 (10.6%) displayed multidrug-resistant tuberculosis (resistant to at least Rifampicin and Isoniazid); 4 (1.3%) were resistant to two or more drugs; and 21 (7%) were resistant to a single drug. Acquired resistance was observed in 70.1% of cases. Drug resistance was significantly associated with previous tuberculosis treatment, duration of HIV diagnosis, and previous hospitalization. In logistic regression analysis, only previous tuberculosis treatment adjusted by age remained as an independent risk factor (OR = 5.49; 95%CI: 2.60-11.60). Drug resistance to at least one drug in 18.9% and multidrug resistance in 10.6% of cases highlight the relevance of this problem in HIV patients in the Baixada Santista.
A new mechanism for SOC scan test scheduling

The paper presents a new mechanism for scan test scheduling in SOC (System On Chip) designs including isolated cores. Scan patterns instead of cores’ test pattern sets are treated as scheduling objects and the channels’ idle time during scan capture period can be utilized. Solution finding under this new mechanism is modelled as a bin packing under color constraint. Sequence pairs and simulated annealing algorithm are used to find the optimal scheduling solution. Experimental results obtained for several large industrial SOC designs show the feasibility of the proposed new mechanism.

Model Driven Approaches to Cross Platform Mobile Development

The mobile market is composed of several mobile platforms (Android, iOS, WP.), each offers its own SDK and requires specific capabilities. With the existing incompatibility between platforms, developing applications for several platforms, separately, is becoming increasingly difficult and need considerable resources. To solve that, cross platform mobile development solutions have been investigated. These solutions are divided into five categories based on the implementation technology on which they are built: web approach, hybrid approach, interpreted approach, cross-platform approach and model driven approach. This paper focuses specifically on the model driven approaches. Our aim is to show the potential of the model driven approaches to increase development productivity and to improve application quality by describing a solution in high-level of abstractions and using models to generate the common aspects of applications. To do so, we try to provide a global description of the actual state of this area.
lnterleukin-1β and phenytoin reduce α1 (1) procollagen mRNA expression in human gingival fibroblasts

Effects of and interactions between interleukin-1 beta (IL-1 beta) and phenytoin (PHT) on alpha 1 (I) procollagen gene and protein expression in human gingival fibroblasts and its relation to prostaglandin E2 (PGE2) formation were studied. IL-1 beta (300 pg/ ml) reduced the steady-state level of alpha 1 (I) procollagen mRNA by 50% and decreased the amount of procollagen I by 35%. PHT (10 micrograms/ml) reduced the level of alpha 1 (I) procollagen mRNA by 40% but the amount of procollagen I in the medium was unchanged. In combination with IL-1 beta, PHT potentiated the inhibitory effect of IL-1 beta on alpha 1 (I) procollagen mRNA level that was accompanied by an increased PGE2 formation. Preincubation with indomethacin (10(-6) M) partially reduced the inhibitory effect of IL-1 beta as well as of IL-1 beta in combination with PHT on the mRNA level of alpha 1 (I) procollagen. The inhibitory effect of PHT was unaffected by indomethacin treatment. Addition of exogenous PGE2 (> or = 10 nM) dose-dependently reduced steady-state level of alpha 1 (I) procollagen mRNA as well as the amount of procollagen 1. The study indicates that IL-1 reduces the expression of alpha 1 (I) procollagen mRNA in human gingival fibroblasts partly by a prostaglandin endoperoxide (PGH) synthase-mediated pathway and partly by a PGH-synthase independent pathway, whereas PHT reduces alpha 1 (I) procollagen gene expression by a PGH-synthase independent pathway. The potentiation of the inhibitory effect of IL-1 induced by PHT was mediated mainly by a PGH-synthase dependent pathway.
Health Information Technology Use Among Men and Women Aged 18-64: Early Release of Estimates From the National Health Interview Survey, January-June 2009

The dynamic involvement of consumers in managing their own health care includes activities such as the use of computers (hardware and software) to access, retrieve, store, or share health care information. This may include using the Internet to look up health information, using e-mail or text messaging to communicate with health care providers or pharmacies, and having an electronic health record. As the percentage of adults in the U.S. who use the Internet continues to grow, the Internet may become increasingly important as a source of health information for consumers. Although use of the Internet has the potential to improve consumer health by facilitating communication between providers and patients, and among providers, previous research (1) has found that many consumers are concerned about security and confidentiality issues related to scheduling medical appointments or accessing personal health records online.
Detecting Malicious Data Injections in Wireless Sensor Networks

Wireless Sensor Networks are widely advocated to monitor environmental parameters, structural integrity of the built environment and use of urban spaces, services and utilities. However, embedded sensors are vulnerable to compromise by external actors through malware but also through their wireless and physical interfaces. Compromised sensors can be made to report false measurements with the aim to produce inappropriate and potentially dangerous responses. Such malicious data injections can be particularly difficult to detect if multiple sensors have been compromised as they could emulate plausible sensor behaviour such as failures or detection of events where none occur. This survey reviews the related work on malicious data injection in wireless sensor networks, derives general principles and a classification of approaches within this domain, compares related studies and identifies areas that require further investigation.
Measuring the Validity and Reliability of the Persian Version of Stanford Health Assessment Questionnaire in Iranian Patients with Osteoarthritis

Article history: Received: 2 Aug 2012 Accepted: 18 Oct 2012 Available online: 6 Jan 2013 ZJRMS 2014 Sep; 16(9): 30-33 Background: Reliability and validity of health assessment questioner have been shown for rheumatoid arthritis but not osteoarthritis in Iranian patients. Having an instrument for measuring of pain and disability is needed for evaluation of patients and disease course in studies. So this study was designed for evaluating of validity and reliability of Persian HAQ in osteoarthritis. Materials and Methods: From 177 patients with hand and/or knee osteoarthritis, 100 patients were chosen according HADS score equal or less than 7. Short Form of Health Survey (SF-36), pain and disability according Visual analogue scale (VAS) and Persian version of Health assessment questioner (HAQ) were completed. HAQ was re-evaluated after one week. Correlation between Persian HAQ, SF 36 and VAS and test-retest reliability were evaluated by Spearman correlation coefficient and Cronbach's alpha coefficient. Results: Correlation coefficient for HAQ 1 and VAS for pain was (r=0.75, p=0.001) and for SF 36 was (r=0.70, p=0.001). Correlation coefficient for HAQ 1 and HAQ 2 was 0.93 for hand OA, 0.96 for knee OA and 0.94 for all patients (r= 0.92, p=0.001). HAQ had a good internal consistency in osteoarthritis (Cronbach's alpha coefficient=0.87). Criterion and structure validity used in study. Conclusion: This study has shown good validity reliability for Persian HAQ in Iranian patients with osteoarthritis. Copyright © 2014 Zahedan University of Medical Sciences. All rights reserved.
Reflected Knowledge and Trust in Global Collaboration

Scholars argue that direct knowledge about distant colleagues is crucial for fostering trust in global collaboration. However, their arguments focus mainly on how trust accrues from knowledge about distant collaborators' personal characteristics, relationships, and behavioral norms. We suggest that an equally important trust mechanism is “reflected knowledge,” knowledge that workers gain about the personal characteristics, relationships, and behavioral norms of their own site through the lens of their distant collaborators. Based on surveys gathered from 140 employees in a division of a global chemical company, we found that direct knowledge and reflected knowledge enhanced trust in distinct ways. Although both enhanced feelings of closeness with others, results indicate that direct knowledge increased focal actors' understanding of their distant colleagues, whereas reflected knowledge promoted feelings of being understood. We discuss implications of reflected knowledge to theories of trust and interpersonal dynamics in globally distributed collaboration. This paper was accepted by Jesper Sorensen, organizations.
Earnings Effects of Entrepreneurial Experience: Evidence from the Semiconductor Industry

Although previous studies have examined the rewards available to individuals inside entrepreneurial firms, entrepreneurial experience may provide rewards that are independent of the entrepreneurial context. Building on human capital theory, this study provides theoretical explanations for the effects of experience at a start-up on earnings across an individual's career and then examines these implications in the context of California's semiconductor industry. Comparing the career trajectories of employees who join start-ups with a matched control group of comparable workers without start-up experience, I perform a counterfactual analysis and find that start-up experience in this context has a persistent positive effect on earnings that extend outside the entrepreneurial environment. The results from the matched sample are consistent with the development and revelation of valuable general human capital through entrepreneurial experience and suggest that the rewards to entrepreneurship are not limited to just the rewards available inside entrepreneurial firms. This paper was accepted by Lee Fleming, entrepreneurship and innovation.
Information Acquisition During Online Decision Making: A Model-Based Exploration Using Eye-Tracking Data

We propose a model of eye-tracking data to understand information acquisition patterns on attribute-by-product matrices, which are common in online choice environments such as comparison websites. The objective is to investigate how consumers gather product and attribute information from moment to moment. We propose a hierarchical hidden Markov model that consists of three connected layers: a lower layer that describes the eye movements, a middle layer that identifies information acquisition processes, and an upper layer that captures strategy switching. The proposed model accounts for the data better than several alternative models. The results show that consumers switch frequently between acquisition strategies, and they obtain information on only two or three attributes or products in a particular acquisition strategy before switching. Horizontal and contiguous eye movements play an important role in information acquisition. Furthermore, our results shed new light on the phenomenon of gaze cascades during choice. We discuss the implications for Web design, online retailing, and new directions for research on online choice.
Pitavastatin Ameliorates Insulin Resistance in Type 2 Diabetic Patients: Report of Two Cases

Introduction: Statins reduce cardiovascular risk in populations targeted for both primary and secondary prevention. The potential of statin use to impact the risk of developing new onset diabetes has been suggested. However, there have been a few large-scale RCTs of pitavastatin which is the statin, but adverse effects on glucose metabolism and diabetes onset were not documented by meta analysis. Case reports: We report two patients with type 2 diabetes and hypercholesterolemia showing amelioration of insulin resistance with pitavastatin. The improvements were attributed to effects of pitavastatin on glucose and insulin metabolism. A 75-year-old man and a 70-year-old woman with type 2 diabetes, hypercholesterolemia and hypertension were given pitavastatin (2 mg/day) for 6 months, without changes in other medication. Before and after treatment, both received euglycemic hyperinsulinemic clamp studies to assess insulin sensitivity. After 6 months, glucose infusion rates were increased in both subjects. Conclusion: These cases suggest that pitavastatin, unlike other statins, has beneficial effects on insulin sensitivity in an insulin-resistant state.
Variation of tactile feelings of focused ultrasound: modulation frequency and hand movement

Ultrasound-based aerial haptic feedback has been studied these days [Hoshi et al. 2010; Carter et al. 2013; Hasegawa and Shinoda 2013]. Studies on this technology mostly focused on producing contact sensation in air and investigating the characteristics of human tactile sensation. There are a few reports on the quality or metaphor of the produced tactile feelings. For example, 100-Hz or 200-Hz modulated ultrasonic stimulation was expressed as "electrostimulation," "a stream of air," and "a small soft-haired blush" in [Hoshi et al. 2010]. Synthesizing realistic tactile feelings, such as recorded from real blanket, is still remaining a difficult technological issue because of controlling hundreds of ultrasonic transducers.
