Assessment of Compliance With RF EMF Exposure Limits: Approximate Methods for Radio Base Station Products Utilizing Array Antennas With Beam-Forming Capabilities

The importance of antenna arrays with beam-forming capability is expected to increase in future mobile communication systems with the ongoing development of new radio access technologies involving higher frequency bands and massive MIMO concepts. In this paper, various approximate methods for radio frequency electromagnetic field compliance assessments of radio base station products utilizing these antenna arrays are investigated with the focus on front compliance distances. For electrically large arrays, the results show that accurate compliance boundary dimensions may be obtained using a field-combining procedure of assessment results for a centrally placed element. For smaller arrays, an overall improvement in accuracy is possible by complementing the center element solution with results for a handful of selected edge and corner elements to better characterize the array behavior. Compared with a general and straightforward approach based on field combining of embedded assessment results for each element, the approximate methods allow for significant reductions of the total assessment time.
Direct electrochemical detection of glucose in human plasma on capillary electrophoresis microchips

We developed an electrochemical detector on a hybrid chip for the determination of glucose in human plasma. The microchip system described in this paper consists of a poly(dimethylsiloxane) (PDMS) layer containing separation and injection channels and an electrode plate. The copper microelectrode is fabricated by selective electroless deposition. The fabrication of the decoupler is performed by platinum electrochemical deposition on the metal film formed by electroless deposition. Factors influencing the performance, including detection potential, separation field strength, and buffer concentration, were studied. The electrodes exhibited good stability and durability in the analytical procedures. Under optimized detection conditions, glucose responded linearly from 10 μM to 1 mM. Finally, glucose in human plasma from three healthy individuals and two diabetics was successfully determined, giving a good prospect for a new clinical diagnostic instrument.
TFIIA Interacts with TFIID via Association with TATA-Binding Protein and TAF40

ABSTRACT TFIIA and TATA-binding protein (TBP) associate directly at the TATA element of genes transcribed by RNA polymerase II. In vivo, TBP is complexed with approximately 14 TBP-associated factors (TAFs) to form the general transcription factor TFIID. How TFIIA and TFIID communicate is not well understood. We show that in addition to making direct contacts with TBP, yeast TAF40 interacts directly and specifically with TFIIA. Mutational analyses of the Toa2 subunit of TFIIA indicate that loss of functional interaction between TFIIA and TAF40 results in conditional growth phenotypes and defects in transcription. These results demonstrate that the TFIIA-TAF40 interaction is important in vivo and indicate a functional role for TAF40 as a bridging factor between TFIIA and TFIID.
An examination of the economic and social benefits from US textile industry strategic partnerships

A strategic partnership is an alliance between companies in which combined corporate strengths are intended to improve outcomes for all members. As a means of maintaining corporate competitiveness in the global economy, some members of the textile industry have established strategic partnerships with other members of the textile and apparel supply chain. The purpose of this study was to investigate business practices of strategic partnerships in the US textile industry with an emphasis on the economic and social value received by partners. Results of a quantitative questionnaire that was completed by 93 respondents in key decision-making positions at US textile manufacturers are discussed, indicating that benefits to partners are derived from strategic partnerships. Finally, a case study of Glen Raven Mills, a global leader in performance fabrics that has multiple strategic partnerships in place, is included. In the case study, key insights about the role partnerships have played in the company’s success are excerpted from an interview with company CEO Allen Gant, Jr.
Complementing open innovation practices in MNCs. The role of internal cross boundary knowledge flows

Open innovation (OI) so far has mainly been understood as a process involving firm external partners. In this paper, we argue that such a focus limits our understanding of how multinational corporations (MNC) profit from internally applied open innovation practices. We thus build on the current OI literature by investigating and describing open innovation activities, conducted within the firm boundaries. Based on a multiple case study of 17 MNCs, our findings reveal five archetypical internal OI practices that vary in underlying management motives. Interestingly, we also find that internal open innovation consistently mitigates some of the fears and risks related to external open innovation and helps MNCs better leverage developments in ICT. Furthermore, we conclude that initial engagement in internal open innovation at MNCs increases the chance to succeed at external open innovation.
Real-time binaural noise reduction in diffuse noise field

In this paper, we present a real-time noise reduction algorithm for binaural sound devices operating in diffuse noise fields. The diffuse noise PSD is estimated in a form of the minimum eigenvalue of the (2×2) input covariance matrix. To solve the under-estimation problem at low-frequencies, a compensation scheme is used. Also, to alleviate spectral bias due to smoothing, the estimated noise PSD is scaled by a smoothing factor. The proposed algorithm was implemented in real-time using a 16-bit programmable DSP core. Real-time implementation indicates that the algorithm requires less than 4MHz clock, so that it is suitable for wearable sound devices such as binaural hearing aids and headphones with noise reduction features.
Diffusive gradient in thin-films (DGT) as risk assessment and management tools in the Central Witwatersrand Goldfield, South Africa

Diffusive gradient in thin-films (DGT) technology was used to monitor bio-available metals and the tool was developed for risk-based pollution assessment and liability apportionment in the Witwatersrand Goldfields, South Africa, where there is widespread mine-related pollution. DGT technology is a passive sampling technique whereby metal species are selectively diffused from polluted water through a diffusion layer and trapped by an inner chelating resin, giving rise to time-weighted average concentrations. The results show that the concentrations of most hazardous metals recorded from grab samples are higher than values recorded from DGT samplers, resulting in inaccurate input information to risk assessors, the public and decision makers. DGT samplers deployed along upper, middle and lower reaches of Elsburgspruit, a stream southeast of Johannesburg, provided data which could assist in evaluating the source and evolution of metals along the stream length. DGT samplers deployed in 5 augers at different depths around a tailings dam showed that liming and trenching fails to contain deep seepage of trace metals. The results highlight the potential of using DGT samplers as a monitoring tool for providing accurate metal pollution information, assessing source and evolution of metals in streams or rivers for apportionment of liabilities, and evaluating the success of current contaminant containment methods.
Variation in the use of business models:essence, levels, and activities

This study examines the ways in which business models are used by market actors in their efforts to create and stabilize business in interaction with others in emerging technology-based service context. This study is interested in the dynamic, processual, and interactive nature of business models instead of their mere structure. By integrating business models into two contemporary discussions on networks and markets, the study widens the scope of business models and explicates the variation in the use of business models. Through a longitudinal study on a service development project the paper shows ways of using of business models by market actors in developing and providing emerging technology-based service offerings. The results of the study show the multi-faceted essence of business models, the levels at which market actors use them, and the activities that market actors perform with them. This study contributes to the business model literature by integrating notions from the network approach and market studies literature. The study also contributes to the network approach by explicating the nature and formation of business nets, and adds to our understanding of market dynamics.
Using Factor Analysis for Residents’ Attitudes towards Economic Impact of Tourism in Nepal

Tourism is one of the fast growing industries and valuable sectors of Nepalese economy, which plays an important role in the development of communities in the Nepalese context. Keeping this point into consideration, this study attempts to examine residents’ attitudes towards economic impact of tourism in Nepal by conducting face to face field survey of 601 respondents from certain tourist destinations with response rate 91.76%. A questionnaire was designed to collect the data and the respondents’ level of agreement has been measured by five point Likert scale. In this study, factor analysis has been used to analyze the impact of tourism in economic development of Nepal. This study finds that the respondents have undergone with both positive and negative economic impacts of tourism. The results of this study also reflect that the development of tourism has helped most of the informants to improve their economic opportunities, sanitation, and livestock production along with the opportunities to utilize alternative energy. It has also caused for the significant rise in price of goods, land and housing. The factor analysis found that 67.84% total variance of perception of residents has been explained by positive impact of tourism and 59.39% total variance has been explained by negative impact of tourism.
Carbapenem Resistance, Initial Antibiotic Therapy, and Mortality in Klebsiella pneumoniae Bacteremia: A Systematic Review and Meta-Analysis

BACKGROUND Mortality associated with infections caused by carbapenem-resistant Enterobacteriaceae (CRE) is higher than mortality due to carbapenem-sensitive pathogens. OBJECTIVE To examine the association between mortality from bacteremia caused by carbapenem-resistant (CRKP) and carbapenem-sensitive Klebsiella pneumoniae (CSKP) and to assess the impact of appropriate initial antibiotic therapy (IAT) on mortality. DESIGN Systematic review and meta-analysis METHODS We searched MEDLINE, EMBASE, CINAHL, and Wiley Cochrane databases through August 31, 2016, for observational studies reporting mortality among adult patients with CRKP and CSKP bacteremia. Search terms were related to Klebsiella, carbapenem-resistance, and infection. Studies including fewer than 10 patients per group were excluded. A random-effects model and meta-regression were used to assess the relationship between carbapenem-resistance, appropriateness of IAT, and mortality. RESULTS Mortality was higher in patients who had CRKP bacteremia than in patients with CSKP bacteremia (15 studies; 1,019 CRKP and 1,148 CSKP patients; unadjusted odds ratio [OR], 2.2; 95% confidence interval [CI], 1.8–2.6; I2=0). Mortality was lower in patients with appropriate IAT than in those without appropriate IAT (7 studies; 658 patients; unadjusted OR, 0.5; 95% CI, 0.3–0.8; I2=36%). CRKP patients (11 studies; 1,326 patients; 8-year period) were consistently less likely to receive appropriate IAT (unadjusted OR, 0.5; 95% CI, 0.3–0.7; I2=43%). Our meta-regression analysis identified a significant association between the difference in appropriate IAT and mortality (OR per 10% difference in IAT, 1.3; 95% CI, 1.0–1.6). CONCLUSIONS Appropriateness of IAT is an important contributor to the observed difference in mortality between patients with CRKP bacteremia and patients with CSKP bacteremia.

Hedonic analysis of open spaces in urban residential neighborhood of Dhaka

Urban open spaces and public recreation lands enhance the environment, economy and quality of life in cities by improving air quality, providing recreational opportunities, and enhancing aesthetic values, among many other benefits. Development decisions in the Dhaka city frequently fail to consider the values of such open spaces. As a result, development occurs in ways that greatly reduce or destroys these open spaces with negative environmental, economic, and social consequences. This study only concerns with the valuation of open spaces specially parks and water bodies of different urban residential neighborhoods of Dhaka city in Economic terms. The real estate is one of the vital catalysts for a country’s economy as urban land value is determinative in both urban planning and real estate activities in economies of today’s world. Within the context of the economic valuation of open space, the presence and absence of open space has an effect on the residential property value in Dhaka is assumed and verified. Together with a set of structural, location and socio-economic variables use to explain residential property prices; the study focuses on three amenity or environmental variables which include the existence of views of park or lake, the distance from the housing unit to the nearest open space, and the size of that open space. To analyze the impact of open space attributes on real price of residential properties, an empirical analysis is carried out by employing Hedonic Price Method (HPM). The regression analysis results from the first stage hedonic estimation reveal that homebuyers are willing to pay only for scenic views and living in the closest proximity to open spaces especially as parks and lakes for both owned and rental houses. This study estimates that the presence of open space views increase the house price on an average 14% of actual price for owner occupied houses and increase the rent price on an average 12% supplementary for rental houses. In the same way, distance from the house to the nearest park is negatively related to the house price. This indicates the marginal implicit price for owner occupied houses increase 5.3%, by reducing the distance between a house and the closest open space by 100ft. In contrast empirical results for proximity to open spaces for rental houses and the size of the nearest open space for both owned and rental houses do not show a statistical significant relationship on nearby property values. As in Dhaka supply of open space is far short of demand therefore less choice makes it difficult to clearly determine the value of property due to the size of nearby open space. This estimated valuation of open spaces and their amenity benefits will be useful in urban design, land use planning and open space preservation decision making.
A Design of a Dynamic Vibration Absorber for a DVD±RW Drive

An optical disk drive is consistently excited by high-speed rotation of a mass-unbalanced disk, which causes vibrations that greatly affect the overall reliability of the reading and writing process. To reduce the vibration, various anti-vibration strategies have been introduced to the optical disk drive industry. One approach is a dynamic vibration absorber. In this paper, the dynamic behavior of a DVDplusmnRW combo drive system with a dynamic vibration absorber was analyzed using a 12 degrees of freedom, rigid, multi-body dynamic model. The effective location and optimal frequency ratio of the dynamic vibration absorber were obtained from the analysis. A dynamic vibration absorber was fabricated based on the analysis and the vibration-reduction performance was confirmed experimentally.
PENGARUH MEKANISME CORPORATEGOVERNANCE TERHADAP KINERJAKEUANGAN

In measuring the financial performance of a company can be seen in several indicators including Earning per Share (EPS), Price Earning Ratio (PER), Return on Equity (ROE), Financial Leverage (FL), Debt to Equity Ratio (DER), Current Assets (CA), dan Return on Assets (ROA). Some of these indicators are used as a guideline for investors to assess the financial performance, but not all of the information that stated in the financial statements was stated properly. In the company that their corporate governance is not running well,, there can be a discrepancy between the information that stated in the financial statements with the fact that happen in company.

While the number of board meetings significant negative effect. From this study only board size and independence of the board of commissioners that significant positive effect on financial performance.
The resolution of neuronal assemblies after cobalt injection into neuropil

Cobalt ions are incorporated by many interneurons of the insect central nervous system after injection of cobalt chloride or cobalt acetate into the neuropil. Entire nerve cells are subsequently revealed by sulphide precipitation which is followed by silver intensification of whole brains and ganglia. The number of neurons resolved depends upon the optimal timing of an injection phase, followed by a period of diffusion. These, and the site of injection, can be adjusted so as to demonstrate arrangements within and between complete populations of morphological classes of interneurons. This novel use of cobalt reveals cytoarchitectural features of neuropil that are refractory to other histological procedures and shows that in columnar visual neuropil the nerve cell arrangements are limited to a few basic modes of assembly.
Novel microstrip stepped-impedance resonator for compact wideband bandpass filters

A novel λ/4 microstrip stepped-impedance resonator with interdigital coupling elements is presented in this paper. By combining the merits of these two structures, strong coupling between adjacent resonators for wideband bandpass filters can be easily obtained and the size of the filter can be largely reduced. More importantly, only a single-sided fabrication process is required in the implementation of the proposed filter. Two four-pole bandpass filters with 0.1 dB equal-ripple bandwidths of 38% and 55%, respectively, are designed and fabricated. Both filters have the advantages of compactness, wide bandwidth, and ease of fabrication.
Seniors face serious driving safety and mobility issues . Older Adults ’ Preferences for Communication with Healthcare Providers About Driving September 2015 A LongROAD Study

Aim To synthesize published qualitative studies to identify older adults’ preferences for communication about driving with healthcare providers. Background Healthcare providers play a key role in addressing driving safety and driving retirement with older adults, but conversations about driving can be difficult. Guides exist for family members and providers, but to date less is known about the types of communication and messages older drivers want from their healthcare providers. Design Qualitative metasynthesis of studies published on or before October 10, 2014, in databases (PubMed, CINAHL, PsycINFO and Web of Science) and grey literature. Review Methods 22 published studies representing 518 older adult drivers met the following inclusion criteria: (1) the study was about driving; (2) the study involved older drivers; (3) the study was qualitative (rather than quantitative or mixed methods); and (4) the study contained information on older drivers’ perspectives about communication with healthcare providers. Results We identified five major themes regarding older adults’ communication preferences: (1) driving discussions are emotionally charged; (2) context matters; (3) providers are trusted and viewed as authority figures; (4) communication should occur over a period of time rather than suddenly; and (5) older adults desire agency in the decision to stop driving. Conclusion Various stakeholders involved in older driver safety should consider older drivers’ perspectives regarding discussions about driving. Healthcare providers can respect and empower older drivers—and support their family members—through tactful communication about driving safety and mobility transitions during the life course.
Path planning with observation prediction to avoid collisions with unknown dynamic obstacles

This paper discusses planning problem for a mobile robot with range sensors that detect obstacles around the robot in unknown dynamic environments. In unknown environments, a mobile robot needs to detect obstacles and finds path without collision to go to destination. Around obstacle information are required by motion and mortion are required to collect information. Therefore, the planning problem with observation need to find path to destination and collect information simultaneously. In this paper, path planning problem for a mobile robot with limited field of view sensors in unknown dynamic environments is discussed. The simulation experiments illustrates the planning method proposed in this paper finds motion to look left-and-right motion before across crossing traffic road.
