Millimeter-wave microstrip diplexer using elliptical open-loop ring resonators for next generation 5G wireless applications

Design of millimeter-wave microstrip diplexer using elliptical open-loop ring resonators (OLRRs) for the next fifth generation (5G) wireless applications, is presented in this paper. The proposed design consists of two 14-GHz and 28-GHz band pass filters (BPFs). Each BPF consists of elliptical OLRRs that couple two microstrip lines. The geometrical parameters of both BPFs can easily adjust the passband and stopband frequencies to the desired frequencies. The proposed elliptical-shaped OLRRs show good broadband characteristics. The longer OLRR is responsible for achieving passband at the lower resonant frequency of 14-GHz while the shorter OLRR is used to generate a 28-GHz resonant frequency. The proposed diplexer has good return losses and insertion losses at the two resonant frequencies of 14-GHz and 28-GHz.
CSR: retailer activities vs. consumer buying decisions

Purpose – The purpose of this paper is to investigate how a retailer’s corporate social responsibility (CSR) activities and image influence consumer perceptions regarding the firm’s social responsibility, and how CSR aspects influence consumers buying decisions in store for a specific product. Design/methodology/approach – A qualitative case study method is used, including interviews, document studies and observations. The CSR approach of a Swedish retailer is investigated at corporate level and in the store, and how this interacts with the views of consumers as they make decisions regarding the purchase of a disposable product. Findings – The authors propose the concept CSR identity to capture the internal efforts and positioning that a retailer attempts to achieve. Store activities and external independent stakeholders will have a main influence on whether the identity is regarded as credible by consumers. Furthermore, factors such as self-image and influences from the social network will influence whet.
Epidemiology and prevention of lung cancer in nonsmokers.

Lung cancer is the leading cause of cancer mortality in the United States accounting for an estimated 28 percent of all cancer deaths in 1998, or a total of 160,100 deaths (1). Lung cancer is also the most common cause of cancer mortality worldwide (2). Although the majority of lung cancers can be attributed to cigarette smoking, particularly in Asian and middle eastern countries, a substantial percentage of lung cancer cases occurs among never smokers (3). For example, the proportion of female lung cancer cases who have never smoked is as high as 65 percent in China (4), 70 percent in Japan (5), and 94 percent in northern India (6). In the United States, typically 9-13 percent of female lung cancer cases are never smokers (7-11). In males, the patterns differ considerably. Among male lung cancer patients, the proportion of never smokers is about 2 percent in the United States (11-13), 3 percent in China (14), 9 percent in Japan (5), and 19 percent in northern India (6).
Community energy storage, a critical element in smart grid: A review of technology, prospect, challenges and opportunity

Community Energy Storage (CES) has been known as a new generation of energy storage that is a crucial element in smart grid. Its location at the edge of the grid and close to customers offers great benefits compare to energy storage located at substation in terms of smoothening the impacts of intermittent Renewable Energy (RE) resources and diversity of Electric Vehicle (EV) operational characteristics. Power utilities found that CES deployment along with reliable planning and control system can become a smart solution in providing sustainable energy and open new business opportunity. However, despite the benefits, CES deployment in distribution system with the integration of PV and EV may face several challenges. This paper provides an overview of CES, covering technology, prospect, challenges and opportunity in obtaining a reliable smart distribution system with optimal cost. In addition, preliminary simulation works are presented to show the effectiveness of CES in reducing power loss and improve voltage profile compare to a central battery located at substation.
A secretary problem with missing observations

Two versions of a best choice problem in which an employer views a sequence of $N$ applicants are considered. The employer can hire at most one applicant. Each applicant is available for interview (and, equivalently, for employment) with some probability $p$. The available applicants are interviewed in the order that they are observed and the availability of the $i$-th applicant is ascertained before the employer can observe the $(i+1)$-th applicant. The employer can rank an available applicant with respect to previously interviewed applicants. The employer has no information on the value of applicants who are unavailable for interview. Applicants appear in a random order. An employer can only offer a position to an applicant directly after the interview. If an available applicant is offered the position, then he will be hired. In the first version of the problem, the goal of the employer is to obtain the best of all the applicants. The form of the optimal strategy is derived. In the second version of the problem, the goal of the employer to obtain the best of the available applicants. It is proposed that the optimal strategy for this second version is of the same form as the form of the optimal strategy for the first version. Examples and the results of numerical calculations are given.
A modified household economic portfolio model for assessing impact of microfinance using diaries

Purpose Microfinance impact evaluation studies help in discovering client needs which are diverse, special and different from the needs of the conventional bankable clients. Thus, such area of market research is becoming essential for microfinance institutions for designing better client-centred products. In this research, the authors discuss the specific model of household economic portfolio (HEP) for qualitative impact evaluation in microfinance. The paper aims to discuss the complexity limitations of the HEP. Solutions are provided for overcoming these limitations. The modified household economic portfolio (M-HEP) model is simplified and detailed, and two types of diaries are suggested for implementing it. Design/methodology/approach First, the authors briefly review the literature on impact assessment methods in microfinance and on the HEP model. In the second part of the paper, the M-HEP is suggested and discussed in detail. In the third part, the authors present a case study to illustrate the additional information that can be generated by using our suggested research tool and model. Finally, the authors wrap up with a summary of the findings. Findings Solutions are provided for overcoming the limitations of the HEP model. The suggested model (M-HEP) is simplified and detailed, and two types of diaries are suggested for implementing it. The case study shows that, certainly, time and money are related. While time may mean money for a rich person, for a poor person, if money is not forthcoming, she may spend time on non-income generating work that adds to her social esteem. She may also consume inexpensive assets because spending time at low cost is important. Finally, she spends time in conducting activities for which she cannot afford to pay. Originality/value The paper offers two novelties. First, it details the interactions between the elements of the HEP model of Chen and Dunn. This improvement to the original model is highly important for defining the measures that are required for redrawing the economic portfolio of an individual. The second novelty is in suggesting the collection of time-use and financial daily data. To the best of our knowledge, this is the first time a combined diary is used in microfinance research. These two novelties allow the application of a modified version of the highly interesting HEP model in spite of its complexity.
Complementary effect of vitamin C and Zinc on some blood cells and serum proteins related to immunity in intact and ovariectomized rabbits

The present experiment was investigated to study the complementary effect of vitamin C and Zinc supplementation on some parameters related to the immune system in intact and ovariectomized rabbits. Twenty female rabbits (7-8 weeks) have been used in this study. Ten of them had been subjected to ovariectomy and the other ten were left with intact ovaries. After recovery from the operation and acclimatization, the rabbits were divided into four equal groups as follow: Group one (G1): Intact rabbits received distilled water. Group two (G2): Intact rabbits received complementary vitamin C and Zinc with the dose (10.166 mg/kg/B.W) orally and daily. Group three (G3): Ovariectomized rabbits received distilled water. Group four (G4): Ovariectomized rabbits received complementary vitamin C and Zinc. The daily supplementation of complementary vitamin C and Zinc induces a significant increase in total leukocytes (14.06 and 11.08 × 103 /mm3) in both intact and ovariectomized rabbits respectively. Moreover, the Arneth, s index reveals a significant higher percentage of neutrophils of four and five lobes in both supplemented groups. The total percentage of mature cells was (27.9% and 14.1%) for G2 and G4 respectively in comparison with (9.0% and 8.3%) for G1 and G3 respectively. There is a significant increase in eosinophil’s and lymphocytes percentages in Ovariectomized rabbits only. However, the result also revealed a significant increase in total protein and total gamma concentration in both intact and ovariectomized rabbits that supplemented with complementary vitamin C and Zinc. In conclusion, the results from this experiment confirm and for the first time that the complementary vitamin C and Zinc supplementation to rabbits has an important protective role on the immune system in ovariectomized rabbits. This supplementation can overcome the deleterious effect of ovariectomy and ovarian hormones deficiency on bodies' immunity.
Social media for large studies of behavior

Large-scale studies of human behavior in social media need to be held to higher methodological standards On 3 November 1948, the day after Harry Truman won the United States presidential elections, the Chicago Tribune published one of the most famous erroneous headlines in newspaper history: “Dewey Defeats Truman” (1, 2). The headline was informed by telephone surveys, which had inadvertently undersampled Truman supporters (1). Rather than permanently discrediting the practice of polling, this event led to the development of more sophisticated techniques and higher standards that produce the more accurate and statistically rigorous polls conducted today (3).
Time course reconstruction of fetal cardiac signals from fMCG: independent component analysis versus adaptive maternal beat subtraction

M-mode and pulsed Doppler echocardiography, cardiotocography and trans-abdominal fetal ECG are available in clinical practice to monitor fetal cardiac activity during advancing gestation, but none of these methods allows the direct measurement of morphological and temporal parameters for fetal rhythm assessment. Fetal magnetocardiograms (fMCGs) are noninvasive recordings of magnetic field variations associated with electrical activity of the fetal heart obtained with superconducting sensors positioned over the maternal abdomen inside a shielded room. Because of maternal cardiac activity, fMCGs are contaminated by maternal components that need to be eliminated to reconstruct fetal cardiac traces. The aim of the present work was to use two methods working in the time domain, an independent component analysis algorithm (FastICA) and an adaptive maternal beat subtraction technique (AMBS), for the retrieval of fetal cardiac signals from fMCGs. Detection rates of both methods were calculated, and FastICA and AMBS performances were compared in the context of clinical applications by estimating several temporal and morphological characteristics of the retrieved fetal traces, such as the shape and duration P-QRS-T waves, arrhythmic beat detection and classification, and noise reduction. Quantitative and qualitative comparison produced figures that always suggested that FastICA was superior to AMBS from the perspective of clinical use of the recovered fetal signals.
The Effect of Silencing HIF-1α Gene in BxPC-3 Cell Line on Glycolysis-Related Gene Expression, Cell Growth, Invasion, and Apoptosis

Hypoxia has been proved to be a typical character of solid tumors. Tumor cells prefer to use glucose through the glycolysis pathway instead of aerobic respiration. However, the precise molecular mechanism underlying this so-called Warburg effect remains elusive. In the current study, siRNA was synthesized and transfected into BxPC-3 cell line to silence the expression of HIF-1α gene. It was found that hypoxia induced hypoxia-inducible factor 1α (HIF-1α) overexpression in BxPC-3 cells, enhanced the expression of pyruvate dehydrogenase kinase 1 and lactate dehydrogenase A, thus facilitating glycolysis and making tumor cells more tolerant to hypoxic stress. The silencing of HIF-1α gene significantly attenuated glycolysis under hypoxic conditions, inhibited the growth and invasion ability of BxPC-3 cells, and enhanced hypoxia-induced cell apoptosis.
The application of in vivo confocal scanning laser microscopy in the diagnosis and evaluation of treatment responses in Mooren's ulcer.

PURPOSE To evaluate the extent of corneal inflammation and the response to treatment in patients with Mooren's ulcer, by in vivo confocal microscopy (IVCM). METHODS Twenty-two eyes of 15 patients with Mooren's ulcer were enrolled in this prospective study. All subjects underwent routine ophthalmic examinations, IVCM, and conjunctival histopathologic examination of specimens in patients undergoing conjunctival excision. Eyes with active ulcer were treated with topical corticosteroids and additional therapy, depending on the signs and symptoms. Eyes in remission continued to receive the previous treatment protocols. The relation between the severity of ulcer and inflammation status as assessed by IVCM was also studied. The endpoints were inflammatory cell density (ICD), counted by IVCM, and the extent of the limbal arc involved with ulcers. RESULTS Ten eyes had active corneal ulcers, and 12 eyes had been in remission for the past year. The mean ICD of eyes with active ulcers before treatment was 2092.7 ± 1538.6 cells/mm(2) (range, 835.3-7832.7; 95% CI, 3232.5-952.9). Nine of the eyes improved at 8 weeks, with a decrease in ICD to 249.1 ± 109.0 cells/mm(2) (range, 100.3-595.3; 95% CI, 329.8-168.3). One eye had corneal perforation, and ICD immediately before perforation was 1677.6 ± 247.6 cells/mm(2). The mean ICD of 12 eyes in remission was 357.5 ± 266.8 cells/mm(2) (range, 12.7-1127.0; 95% CI, 555.2-159.8). The correlation of the ICD and the extent of limbal involvement with ulcers was strong (R(2) = 0.8119). CONCLUSIONS ICD evaluated by IVCM is a useful and promising parameter for evaluation of the degree of inflammation in eyes with Mooren's ulcer and for assessment of response to treatment.
Effect of the combination of NAA, kinetin and sucrose on the induction of somatic embryogenesis in lulo (Solanum quitoense Lam.)

El lulo es una especie de gran importancia en la fruticultura colombiana, con grandes problemas fitosanitarios que requieren un agresivo programa de mejoramiento orientado a la produccion de variedades tolerantes. Estos programas necesitan establecer protocolos de propagacion masiva de plantas de alta eficiencia como la embriogenesis somatica. Nuestras investigaciones se orientaron al estudio de la embriogenesis somatica de lulo, mediante la interaccion de los fitorreguladores kinetina y acido naftalenacetico (ANA), y diferentes concentraciones de sacarosa en medio MS . Se utilizaron dos variedades de lulo ( Solanum quitoense var. septentrionale y S. quitoense var. quitoense ), dos tipos de explantes (hojas cotiledonares e hipocotilos), incubados en condiciones de oscuridad, a 25±2°C. El mayor porcentaje de produccion de embriones se obtuvo cuando se adicionaron al medio 50 m M de ANA ademas de sacarosa (50,0 y 263,1 m M), para los dos tipos de explantes utilizados. En lulo con espinas, el mayor porcentaje de estructuras embrionarias (50%) se observo con hojas cotiledonares y 50 m M de NAA, mientras que en lulo sin espinas estos se observaron en el mismo tipo de explante con 50 m M NAA + 263,1 m M sacarosa (32%).
Manufacturing: the new case for vertical integration

The article argues that the solid corporation will continue to view vertical integration as a critical part of manufacturing reform. Manufacturing reform and backward integration are related in insidious ways to the three stages of production over which the big manufacturers preside. Without integration, technology-based corporations may wind up pauperizing upstream components producers in order to earn premiums for downstream assembly and distribution operations, businesses that are comparatively flush. The authors elaborate on the production process which are divided into three stages: the assembly stage, the sub-assembly stage, and the component stage; at each there is a separate tier of factories and businesses. They also discuss the implications of the Western companies' leaning toward less integration.
Filtering algorithm based on the maximum likelihood with partial parameters unknown

This paper deals with the state filtering problem of nonlinear state-space functions with partial parameters unknown. A novel filtering algorithm is proposed based on a modified maximum likelihood method. Using a new likelihood probabilistic function, we obtain a two-stages strategy of Expectation and Maximization (EM) with the help of Monte Carlo method. The convergence of EM parameter updating strategy is verified theoretically and the proposed algorithm is an iterative process of these two stages. Here we use modified maximum likelihood method for parameter identification and particle filtering method for state estimation at current time moment. The proposed algorithm no longer uses all the observed values for iteration but only the current observed values, so it is simple for calculation and has advantages for application to online parameters identification. Simulation result proves that the proposed algorithm works effectively.
An approach to detect network attacks applied for network forensics

Network forensics is addressed to deal with cybercrime. The main purpose of a network forensics system is reconstructing evidences of network attacks. In order to reconstruct evidence, the network attack is firstly identified. Therefore, network attack detection solutions play an important role in network forensics. There are two main types of network attacks: network level and application level. Network level attack detection solutions focus on the information in the headers of network packets. While, application level attack detection solutions investigate the data fragments carried out in the packet payloads. We propose an approach based on Shannon entropy and machine learning techniques to identify executable content for anomaly-based network attack detection in network forensics systems. Experimental results show that the proposed approach provides very high detection rate.
Congenital absence of the spleen with congenital heart disease; report of a case with ante mortem diagnosis on the basis of hematologic morphology.

1. The clinical, hematologic and post mortem findings in a case of splenic agenesis have been presented. Because of its association with cyanotic congenital heart disease and situs inversus of the abdominal viscera, the anomaly was suspected prior to death. The presence of hematologic abnormalities similar to those found after splenectomy supported this impression. These abnormalities were: target cells, decreased osmotic fragility, Howell-Jolly bodies, transient normoblastemia, siderocytosis, and leukocytosis. 2. The blood picture in splenic agenesis is sufficiently specific to permit the antemortem diagnosis to be suspected even in the absence of severe associated anomalies.
The Influence of Outcome-Oriented Security Policy on Security Perceptions and Intentions

With security breaches occurring regularly, organizations must employ strong security countermeasures to protect private, valuable information. Organizational insiders pose a major threat to the security of organizations by direct and intentional misuse of information assets and by the careless and negligent use of information. Developing strong information security policy (ISP) is important to thwarting insider security threats. To date, behavioral information security research has primarily examined ISP from a procedural viewpoint. Outcome-oriented security policy is understudied. This research-in-progress proposes a study of security policy to determine how the inclusion of outcome-oriented security policy influences insiders’ attitudes toward and intentions to follow procedural security policy. An experiment is proposed to test the hypotheses.
Contexts and behavioral correlates of trill vocalizations in wild white‐faced capuchin monkeys (Cebus capucinus)

Primate vocalizations that appear to occur independently of specific contexts typically are considered to be contact calls. However, results from several recent studies indicate that these calls function to facilitate social interactions. White‐faced capuchin monkeys (Cebus capucinus) emit a high‐frequency vocalization, termed a “trill,” in social interactions and during travel. In this study, immatures emitted most trills, but adult females also trilled; by contrast, adult males rarely trilled. Infants emitted the majority of trills, and they trilled at significantly higher rates than adult females. Infants trilled most when approaching other individuals. Furthermore, infants emitted proportionately more trills than other age classes when approaching other individuals. I therefore focused on the detailed context and immediate behavioral correlates of trilling by infants. Infants that trilled when approaching others tended to interact affiliatively with them subsequently (i.e., climbing on, touching, receiving grooming, and performing food inspection) more than infants that did not trill when approaching. Therefore, infant trilling may have had an immediate effect on the recipient's behavior. Am. J. Primatol. 57:189–202, 2002. © 2002 Wiley‐Liss, Inc.
Improving LMI controllers for discrete nonlinear systems using policy iteration

This paper presents a method to improve the conservative (shape-independent) controllers from guaranteed-cost LMIs using Q-learning policy iteration setups which learn optimal controllers from data. In this context, the proposed approach uses an initial parametrization based on the LMI solution and the learning process includes parameters related to the nonlinearity of the system (and its gradient). An approximation of the Q-function using polynomials of the membership functions in Takagi-Sugeno models is obtained using a policy iteration algorithm. The resulting controller is shape-dependent, that is, uses the knowledge of membership functions, their gradients and data to improve well-known LMI solutions.
