Analytical design of novel triple‐passband microwave filters using frequency transformations method

In this article, a triple‐band filter is presented.This design is based on the suitably defined frequency transformations and uses well‐established prototype synthesis techniques, and the coupling coefficients and the external quality factors can be calculated analytically. In the realization, the triple‐band resonator is utilized to replace each capacitance in the low‐pass prototype circuit as the building block of the triple‐band filter. To validate the synthesis method, a practical triple‐passband filter is designed and fabricated with passbands at 3.3–3.4 GHz, 3.5–3.6 GHz, and 3.7–3.8 GHz, respectively, which has a maximum return loss of 20 dB in each passband. © 2011 Wiley Periodicals, Inc.

Parkin beyond Parkinson’s Disease—A Functional Meaning of Parkin Downregulation in TDP-43 Proteinopathies

Parkin and PINK1 are key regulators of mitophagy, an autophagic pathway for selective elimination of dysfunctional mitochondria. To this date, parkin depletion has been associated with recessive early onset Parkinson’s disease (PD) caused by loss-of-function mutations in the PARK2 gene, while, in sporadic PD, the activity and abundance of this protein can be compromised by stress-related modifications. Intriguingly, research in recent years has shown that parkin depletion is not limited to PD but is also observed in other neurodegenerative diseases—especially those characterized by TDP-43 proteinopathies, such as amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Here, we discuss the evidence of parkin downregulation in these disease phenotypes, its emerging connections with TDP-43, and its possible functional implications.

Steady-state Modeling and Analysis of Six-phase Self-excited Induction Generator for Renewable Energy Generation

Abstract This article presents the steady-state modeling and analysis of a six-phase self-excited induction generator for stand-alone renewable generation. The basis of the analysis is the nodal admittance method based on graph theory as applied to the equivalent circuit. The proposed steady-state generalized model of a six-phase self-excited induction generator dispenses with the tedious work of segregating real and imaginary components of the complex impedance of the induction generator for deriving the specific models for each operating mode. Graph theory based matrix equations are easier to modify in order to account for specific effects such as uncompensated and compensated operation. The resulting equations have excellent symmetry, which makes the analysis very easy, fast, and accurate. The matrix equations developed by the nodal admittance method are solved by a genetic algorithm to determine the steady-state performance of a six-phase self-excited induction generator. The analytical results are found to be in good agreement with experimental results.
Family businesses in the tourism industry: a research agenda

PurposeThe purpose of this study is to construct a comprehensive review on family businesses in the tourism industry since glocalization and small businesses comprise most of the industry.Design/methodology/approachThis is a conceptual paper which utilizes qualitative research methods. Bibliometric analysis is applied to the selected 35 articles from specific databases which include not only the general tourism industry but also subsectors of airline, hospitality, restaurant, etc. Articles in this study fixate on the family businesses within the tourism industry.FindingsIn total, 35 articles are found with the keywords “family business and tourism”, “family business and hospitality and hotels”, “family business and restaurant” and “family business and airline”. Though the family business studies focus on hospitality, tourism and restaurants as F&B, there is a research gap in the subsectors like rent-a-car companies, travel agencies and tour operators and recreation facilities. Overall qualitative research design is preferred, but majority of the authors’ focus is on business development, profit, performance and succession. For further studies, quantitative analysis on research gap areas are recommended.Research limitations/implicationsThe most general limitation is that only specific selected databases are used for the data gathering process such as double reviewed indexed journals published within Web of Science, Emerald, Elton B. Stephens Company (EBSCO) and Elsevier databases from the period of 1970s. Some other databases and some different periods may be considered as well as different keywords for other research. Secondly, few studies have analyzed quantitative data, since the specific nature of the family business dynamics require qualitative data. As a suggestion, not only qualitative analysis but also mixed methods may also be studied since the literature lacks the studies conducted with these methodologies.Originality/valueThe study contributes to the existing literature by providing a comprehensive review on hospitality and tourism family business management emphasizing the research gap on subsector application areas.
The effect of supplier CSR practices on sales performance with major customers in B2B markets

ABSTRACT If supplier firms motivate their major customers to boost sales performance, they can gain a significant competitive advantage. This study draws on the signaling theory and the strategic CSR literature to explore how and when supplier CSR practices affect their sales performance with major customers. Using data from 1,294 Chinese publicly listed firms for the period from 2010 to 2019, this study indicates that supplier CSR practices increase sales performance with major customers. This association is stronger when major customers also proactively engage in CSR. Furthermore, the interaction effect between supplier and customer CSR practices is strengthened when the geographical distance between supplier and customer firms is greater and when industry competition is strong. The findings provide theoretical and managerial implications for the strategic role of CSR in supplier–customer relationships in B2B markets.
modelSampler: An R Tool for Variable Selection and Model Exploration in Linear Regression

We have developed a tool for model space exploration and variable selection in linear regression models based on a simple spike and slab model (Dey, 2012). The model chosen is the best model with minimum nal prediction error (FPE) values among all other models. This is implemented via the R package modelSampler. However, model selection based on FPE criteria is dubious and questionable as FPE criteria can be sensitive to perturbations in the data. This R package can be used for empirical assessment of the stability of FPE criteria. A stable model selection is accomplished by using a bootstrap wrapper that calls the primary function of the package several times on the bootstrapped data. The heart of the method is the notion of model averaging for stable variable selection and to study the behavior of variables over the entire model space, a concept invaluable in high dimensional situations.
Examination of oxide damage during high-current stress of n-MOS transistors

Damage to n-channel MOSFETs under different levels of drain current stress is compared. It is shown that the post-stress I/sub d/-V/sub gs/ characteristics show distinctly different behavior for different stresses. These differences are interpreted in terms of the location of the stress damage along the Si-SiO/sub 2/ interface. It is shown that damage from low drain current stress occurs at the Si-SiO/sub 2/ interface just inside the drain junction, under strong gate control. Damage from high drain current stress occurs at the Si-SiO/sub 2/ interface deeper inside the drain junction region, under weak gate control. The damage localization interpretation is supported by simulations and by localized Fowler-Nordheim injection experiments. It is further shown that at intermediate levels of drain current injection, the damage occurs at the Si-SiO/sub 2/ interface in both drain regions. The differences are explained in terms of the bipolar action at high drain current levels, which forces the channel charge away from the Si-SiO/sub 2/ interface at the drain junction edge. >
Determining Appropriate Screening Tools and Cutoffs for Cognitive Impairment in the Chinese Elderly

Background: The Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) are the most commonly used tools for cognitive impairment screening. The present study aimed to investigate the ability of the MOCA and MMSE to differentiate between cognitively normal elderly individuals, MCI patients and dementia patients at different ages and education levels and to establish the optimal cutoff scores of the MoCA and MMSE for MCI and dementia in the Chinese elderly. Methods: A total of 2,954 Chinese elderly individuals, including 1,746 normal controls, 599 MCI patients and 249 dementia patients, were consecutively recruited in the study. The optimal cutoffs for MoCA and MMSE were determined using receiver operating characteristic (ROC) analysis among the different age and education levels in the three groups. Furthermore, comparison of ROC curves were made to evaluate the performances of the two tests. Results: The area under the curve(AUC) of the MoCA (0.82) for detecting MCI was significantly higher than that of the MMSE (0.75) (P < 0.001). When the sample was divided according to age and education level, the AUC of the MoCA (0.84) was higher than those of the MMSE (0.71) for MCI (P < 0.001) in the younger and more highly-educated groups. The optimal cutoff scores of the MoCA for the groups aged ≤ 75 years old and education ≤ 6 years, aged > 75 years old and education ≤ 6 years, aged ≤ 75 years old and education > 6 years, aged > 75 years old and education > 6 years in screening for MCI were identified as 19.5, 15.5, 24.5 and 24.5, respectively, and the optimal cutoff scores for dementia were 18.5, 10.5, 18.5 and 20.5, respectively. For MMSE in the above four groups, the cutoff scores to detect MCI were 26.5, 22.5, 28.5 and 26.5, respectively, and the optimal cutoff scores for dementia were 23.5, 19.5, 23.5 and 23.5, respectively. Conclusion: Compared to MMSE, the MoCA is more suitable for discriminating MCI in younger and more highly educated elderly Chinese individuals. However, the MMSE has advantage over MoCA in screening MCI in individuals with lower education levels and the older groups of Chinese elderly.

Assessment of Heavy Metal Levels in Soil and Vegetables in Some Farms Around Mining Sites in Mangu Local Government Area Plateau State, Nigeria

When the mining process is not properly controlled, it can be a source of heavy metals pollution in the environment. The uptake of these heavy metals in edible parts of vegetables can be a direct source of the metals into the human food chain. This study assessed the concentrations of lead (Pb), manganese (Mn), zinc (Zn), copper (Cu), nickel (Ni) and chromium (Cr) in soil and vegetables obtained from nine (9) farms around mining sites in Mangu LGA. Concentrations of heavy metals in soil and vegetables were determined using atomic absorption spectrophotometer (AAS). The results revealed the concentrations of the heavy metals at the farms to be within the recommended maximum levels of world soils but were higher than their respective controls. This implies that the artisanal mining contributed to the increased values of these heavy metals in the environment. Also, the mean concentrations of the heavy metals at Mangu Halle mining site decreased in the order Mn > Zn > Cr > Cu > Ni > Pb > Cd whereas at Alogwom it decreased in the order Mn > Zn > Pb > Cu > Ni > Cr > Cd. The enrichment factor (EF) of the elements showed deficiency to minimum enrichment for all the heavy metals whereas the pollution index (PI) of the metals indicated very slight contamination to moderate pollution. The results of the heavy metals in the vegetables showed that the bioaccumulation of the metals followed a pattern: Zn > Cu > Pb > Cr > Cd > Ni. Levels of Cd, Pb and Ni in the vegetables were observed to be higher than the recommended limit for vegetables whereas Cu, Cr and Zn exhibited lower values than recommended standards. Thus, their consumption might pose health risk to consumers and therefore there is the need for proper monitoring of the illegal mining activities to reduce health risk and the extent of heavy metals contamination.
Minimization of ruin probability with joint strategies of investment and reinsurance

Abstract We investigate the problem of minimizing ruin probability by joint decisions of excess-of-loss reinsurance and investment in a financial market. The insurer’s reserve is modeled by a diffusion process and may be invested in a financial market consisting of a risky asset with the price process following the geometric Brownian motion and a risk-free asset with a fixed return rate. Borrowing is allowed, but with an interest rate higher than the interest rate of the risk-free investment. Meanwhile, an excess-of-loss reinsurance may be purchased to alleviate the risk of ruin. We apply stochastic control theory and find the optimal strategy of joint reinsurance and investment decisions, and derive the closed form expression of the minimum ruin probability function. Results are illustrated numerically.
Novel Harziane Diterpenes from Deep-Sea Sediment Fungus Trichoderma sp. SCSIOW21 and Their Potential Anti-Inflammatory Effects

Five undescribed harziane-type diterpene derivatives, namely harzianol K (1), harzianol L (4), harzianol M (5), harzianol N (6), harzianol O (7), along with two known compounds, hazianol J (2) and harzianol A (3) were isolated from the deep-sea sediment-derived fungus Trichoderma sp. SCSIOW21. The relative configurations were determined by meticulous spectroscopic methods including 1D, 2D NMR spectroscopy, and HR-ESI-MS. The absolute configurations were established by the ECD curve calculations and the X-ray crystallographic analysis. These compounds (1, and 4–7) contributed to increasing the diversity of the caged harziane type diterpenes with highly congested skeleton characteristics. Harzianol J (2) exhibited a weak anti-inflammatory effect with 81.8% NO inhibition at 100 µM.

Idea Expander: Agent-Augmented Online Brainstorming

Group brainstorming is a commonly practiced technique to enhance creative outcomes. A close observation of the social and cognitive processes of group brainstorming suggests that ensuring the abundance and diversity of stimuli available in the brainstorming session is critical. We propose to support group brainstorming by presenting pictures related to the conversation that are retrieved and chosen by a computer agent. Communicative, perceptual and cognitive processes are orchestrated to form a sociotechnical system that may help produce more and better creative ideas. Author Keywords Creativity support tool, group brainstorming
Highly efficient non-degenerate four-wave mixing process in InAs/InGaAsP quantum dots

A highly efficient non-degenerate four-wave mixing (FWM) process using CW pump and probe signals around the L-band wavelength range in an InAs/InGaAsP quantum dot semiconductor optical amplifier (QD-SOA) is experimentally demonstrated for the first time. The preliminary experimental results indicate that the FWM efficiency using QD-SOA is independent of the sign of the frequency detuning and decreases by less than 20 dB/decade with frequency detuning increasing.
INCREASING SAFETY BY STRESS MANAGEMENT

Psychosocial factors play an important role in occupational health and safety. Stress is probably the most prevalent psychosocial problem and hence stress management ranks among the most promising health and safety promoters. This contribution deals with the stress of air traffic controllers (ATCOs) which results from workload on the one hand and the responsibility for air traffic safety on the other. Four steps in the stress management of German ATCOs will be described aiming at increasing air traffic safety and reducing stress: A current state analysis with 328 employees of the German Air Traffic Control Services (DFS) revealed a sufficient quantity and quality of safety instruments. In several field and simulation studies with 130 operational staff, the most important workload factors were identified and implemented in the work agreement. Now German controllers are paid and given breaks according to th eir workload measured as the number of aircraft under control, the probability of conflict situations between aircraft and pilot errors in the particular airspace, as well as the percentage of climbing/descending opposed to level flying aircraft. A simulation study with 40 air traffic controllers proved active relaxation to accelerate the recovery after work and to prevent safety problems . Controllers can experience critical incidents like separation losses between aircraft, near misses or accidents. A critical incident stress management (CISM) can support coping with these problems as a questionnaire survey with 60 air traffic controllers showed. This study was conducted for Eurocontrol, Brussels, and revealed also an improvement of safety culture by the DFS CISM programme. Moreover, an economic return on investment could be proven: Controllers reported a quicker and more sustainable recovery from critical incidents. In conclusion the DFS implemented a comprehensive safety and stress management which maintains the highest standard of air traffic safety and reduces work stress related problems. In the long run, these measures will pay off also economically.
TQM in Australian manufacturing: factors critical to success

Discusses the trends in the adoption of quality management practices in the Australian manufacturing industry and highlights some of the barriers to the adoption of such practices. Furthermore, the paper discusses the factors that are considered to be critical to the adoption of TQM in Australian manufacturing. The longitudinal quantitative and qualitative results show that TQM is largely implemented in the manufacturing/operations function with little progress in other functional areas. Overall, the popularity of TQM, ISO 9000 certification, statistical process control and quality circles has diminished. The obstacles to the adoption of quality management practices point to the short‐term vision of Australian managers and the misconception concerning the costs and benefits associated with a TQM programme. Based on the results of surveys and the case study research, numerous factors critical to success are identified. Concludes that there is no single best approach to implementing the TQM philosophy. An approach unique to the needs and culture of the organization must be developed.
Warning Success Rate: Increasing the Convective Warning's Role in Protecting Life and Property

Warning Success Rate, defined as the percentage of the warned population that receives, correctly interprets, and appropriately responds to a given warning message, is a new way to look at the potential impact of warnings on the effort of protecting life and property. Whereas present day efforts to evaluate warning success focus on accuracy and timeliness statistics, Warning Success Rate focuses on warning utilization, with emphasis on three key measures: reception, interpretation, and response. Is an accurate and timely warning meaningful if it is received, correctly interpreted, and utilized by only a small fraction of the warned population?
An improved transmission-line model of grounding system

This paper presents a time-domain transmission line model of grounding system, which includes the mutual electromagnetic coupling between the parts of the grounding structure and the influence of air-earth interface. The model can be used to simulate the transient behavior of the grounding system under lightning strike. The simulation results are in good agreement with that of the model based on the solution of full Maxwell's equations. The influence of different parameters, such as the soil relative permittivity /spl epsi//sub /spl tau//, the soil resistivity /spl rho/, and the conductivity and diameter of the conductor, on the transient voltage distribution of the grounding system is investigated. It shows that, among the parameters investigated here, the soil resistivity is the most important parameter that affects the transient response of bare buried conductors. The soil permittivity has very little influence on the transient response of the grounding system when the grounding system is buried in the soil with low resistivity, but have moderate influence in the soil with extremely high resistivity. The conductivity of the conductor and skin effect have practically no influence on the peak transient voltage of the grounding system. Increase in conductor diameter tends to decrease the peak transient voltage. The model presented in this paper is simple, but sufficiently accurate and can be used easily in engineering practice. Since the model is in the time domain, it could be easily coupled to the other time-domain models of nonlinear surge-protection components.
