Aspects of capacity enhancement techniques in cellular networks

The target of this paper is to investigate different traffic handling strategies to increase the capacity of the network. Impact of deploying UMTS900 with other GSM900/1800 and UMTS2100 layer was also observed in terms of capacity of the network. Number of mobile users is increasing enormously, and it is expected that the demand for data services and different kind of multimedia services will grow with accelerated pace. UMTS2100 has been deployed to meet the requirement of data services. But due to higher frequency band of operation, signals at higher frequencies experience more path loss. Therefore, to provide better coverage to indoor data users more sites of UMTS2100 are required. UMTS900 deployment provides the solution for high deployment cost, and it provides the better coverage as compared to UMTS2100. The deployment of UMTS900 as an overlay with UMTS2100 also helps in enhancing the network capacity, both for the voice traffic and data traffic. A position and service based call handling scheme is proposed in this paper. Results of this paper show that by adopting proposed traffic handling strategy, capacity of the network can be increased.
Innovation in services: present findings, and future pathways

Purpose – The purpose of this paper is, firstly, to review existing schools of thought and to identify present research fields in new service development (NSD) and service innovation research, and, secondly, to discuss future research opportunities.Design/methodology/approach – The literature review is based on a search for “service innovation” and “NSD” in titles, abstracts and keywords of articles. As a result of looking at the references, as well as through analysis of papers which cite the articles identified, additional publications are included in this study.Findings – Four schools of thought and five distinct research fields are presented. Herein, the authors show that there is a lack of studies of organisational innovations, and that differences in the drivers for radical or incremental innovations may be of degree rather than of kind. Further, contradictory results in the research field on differences versus similarities of new product and NSD are identified. In addition, the authors propose poss.
An Empirical Analysis on the Development Route of Commercial Bank's Intermediary Business

In the past 15 years, additional non-interest income, composed of asset service income, securitization business income, investment banking income, insurance-related income and other operational service incomes, drives non-interest income of US commercial banks grow by leaps and bounds. In fact, commercial bank's intermediary income mainly stems from account service, transaction service and credit service. Therefore, the development route of intermediary business of Chinese commercial banking should be targeted at establishing account service, expanding transaction service, furthering credit service and paying close attention to mixed operation. The realization of this development route strategy relies on creating effective leadership, forming ladder-like abilities and making scientific innovations.
Imaging single mammalian cells with a 1.5 T clinical MRI scanner

In the present work, we demonstrate that the steady‐state free precession (SSFP) imaging pulse sequence FIESTA (fast imaging employing steady state acquisition) used in conjunction with a custom‐built insertable gradient coil and customized RF coils can be used to detect individual SPIO‐labeled cells using a commonly available 1.5 T clinical MRI scanner. This work provides the first evidence that single‐cell tracking will be possible using clinical MRI scanners, opening up new possibilities for cell tracking and monitoring of cellular therapeutics in vivo in humans.

Reduction of the input current harmonic content in matrix converters under input/output unbalance

This paper deals with the performance evaluation of space vector modulation controlled matrix power converters under input and output unbalanced conditions. Two control strategies are presented and compared with reference to the input current harmonic content. The first strategy is based on keeping the input current vector in phase with the input voltage vector. In the second strategy, the input current vector is modulated along a direction depending on positive and negative sequence components of the input voltages. In both cases, the harmonic content of the input current has been evaluated analytically. It has been verified that the input current harmonic spectrum is quite different for the two control strategies and can be related to the input and output unbalance. Some numerical simulation are presented to confirm the analytical results.
Enterprise Resource Planning Implementation and Accounting Information Quality

This study investigates the effect of ERP system implementation on accounting information quality of firms listed in Indonesian Stock Exchange. The accounting information quality proxies are relevance and faithful representation. Relevance is measured with time lag between fiscal year-end and earnings announcements date, whereas faithful representation is measured with absolute discretionary accrual. The study finds that the implementation of ERP system increase the absolute discretionary accrual, thus the faithful representation of the accounting information decreases. With respect to relevance, firms with incentive to increase the timeliness of earning release date experience a decrease in reporting lag after implementing ERP system. Keywords-ERP system implementation; discretionary accruals; relevance; faithful representation
The Mirage of Marketing to the Bottom of the Pyramid: How the Private Sector Can Help Alleviate Poverty

The popular "bottom of the pyramid" (BOP) proposition argues that large companies can make a fortune by selling to poor people and simultaneously help eradicate poverty. While a few market opportunities do exist, the market at the BOP is generally too small monetarily to be very profitable for most multinationals. At the same time, the private sector can play a key role in poverty alleviation by viewing the poor as producers, and emphasize buying from them, rather than selling to them.
The role of molecular analysis in the diagnosis and surveillance of pancreatic cystic neoplasms.

CONTEXT Molecular analysis of pancreatic cyst fluid obtained by EUS-FNA may increase diagnostic accuracy. We evaluated the utility of cyst-fluid molecular analysis, including mutational analysis of K-ras, loss of heterozygosity (LOH) at tumor suppressor loci, and DNA content in the diagnoses and surveillance of pancreatic cysts. METHODS We retrospectively reviewed the Columbia University Pancreas Center database for all patients who underwent EUS/FNA for the evaluation of pancreatic cystic lesions followed by surgical resection or surveillance between 2006-2011. We compared accuracy of molecular analysis for mucinous etiology and malignant behavior to cyst-fluid CEA and cytology and surgical pathology in resected tumors. We recorded changes in molecular features over serial encounters in tumors under surveillance. Differences across groups were compared using Student's t or the Mann-Whitney U test for continuous variables and the Fisher's exact test for binary variables. RESULTS Among 40 resected cysts with intermediate-risk features, molecular characteristics increased the diagnostic yield of EUS-FNA (n=11) but identified mucinous cysts less accurately than cyst fluid CEA (P=0.21 vs. 0.03). The combination of a K-ras mutation and ≥2 loss of heterozygosity was highly specific (96%) but insensitive for malignant behavior (50%). Initial data on surveillance (n=16) suggests that molecular changes occur frequently, and do not correlate with changes in cyst size, morphology, or CEA. CONCLUSIONS In intermediate-risk pancreatic cysts, the presence of a K-ras mutation or loss of heterozygosity suggests mucinous etiology. K-ras mutation plus ≥2 loss of heterozygosity is strongly associated with malignancy, but sensitivity is low; while the presence of these mutations may be helpful, negative findings are uninformative. Molecular changes are observed in the course of cyst surveillance, which may be significant in long-term follow-up.
Knowledge Sharing and Knowledge Transfer Barriers. A Case Study

The purpose of this research work was to investigate and to determine existing knowledge sharing and knowledge transfer barriers in the company. The research takes place in one company. This company produces mineral wool, which is used for buildings. The company was established in March 2010. The research units were several departments: a Logistics Department, an Export and Import Department, a Trading House, Accounting Department, a Legal Department, a Quality Department, a Security Department and a Technical support with IT Department. Our philosophical world view was the pragmatism. We used mixed method research, the sequential exploratory design. For qualitative research we used interview with open-ended questions to collect data. Data was analyzed by the coding system and by finding the common relationships and patterns. For the quantitative research we used the questionnaire with close-ended questions. Data was analyzed by statistics methods. Literature review was made and additional documents were collected to obtain detailed information about knowledge sharing and knowledge transfer processes in the organization. For our research work we used the case study inquire. Results showed that the most critical factors that impact on knowledge transfer and knowledge sharing were the motivation and the trusting relationships. We suggested several solutions to overcome these barriers in order to improve knowledge transfer and knowledge sharing in the research company.

Foreign Bank Supervision and Challenges to Emerging Market Supervisors

The increased presence of foreign banks in a country`s domestic banking system necessitates the development of effective cross-border prudential supervision where the consolidated supervision is the essential element. This paper presents foreign bank supervision in terms of division of responsibilities between the home and host countries, consolidated supervision, quality of home-country supervision, memoranda of understanding (MOUs), and "ring-fencing" of banks. A number of challenges which foreign banks bring to emerging market banking supervisors are also discussed. The paper also provides surveys of country cases.
Effects of environmental antiandrogens on reproductive development in experimental animals

Chemicals that act as androgen receptor (AR) agonists and antagonists or inhibit fetal steroidogenesis can induce reproductive malformations in humans and laboratory animals. Several environmental chemicals disrupt development in rats and/or rabbits at fetal concentrations at, or near, exposure levels seen in some segments of the human population. In rats, fetal tissues concentrations of 10–20 p.p.m. of the DDT metabolite, p,p'‐DDE, are correlated with reproductive abnormalities in male offspring. These concentrations are similar to those measured in first‐trimester human fetal tissues in the late 1960s. The pesticides vinclozolin, procymidone, linuron and DDT are AR antagonists. They reduce male rat anogenital distance, and induce areolas at relatively low dosages. Hypospadias, agenesis of the sex accessory tissues and retained nipples are seen in the middle dosages, while undescended testes and epididymal agenesis are seen in the highest doses. Phthalate esters (PE) inhibit testosterone synthesis during fetal life, but do not appear to be AR antagonists. Prenatal administration of a single low dose of dioxin (50–1000 ng TCDD/kg) alters the differentiation of androgen‐dependent tissues at p.p.t. concentrations, but the mechanism of action likely involves interaction with a hormone‐like nuclear transcription factor, the hormone‐like receptor AhR, rather than AR. p,p'‐DDT and p,p'‐DDE, vinclozolin and di‐n‐butyl phthalate affect reproductive function in rabbits when administered during prenatal and/or neonatal life. Cryptorchidism and carcinoma in situ‐like (CIS) testicular lesions were seen in male rabbits treated during development with p,p'‐DDT or p,p'‐DDE. Extrapolation of effects from rodents to humans would be enhanced if future studies incorporate determination of tissue concentrations of the active metabolites. Knowledge of the tissue concentrations of the active toxicants also would provide an important link to in‐vitro studies, which provide more useful mechanistic information when they are executed at relevant concentrations.
Freight Transport Modelling of Container Hinterland Supply Chains

Macroeconomic freight transport models serve as decision support for transport policy development. To evaluate infrastructure investments or policy measures these tools need to capture the underlying complexity of freight transport networks in a sufficient way. Recent developments in this field outline possibilities to combine aggregated and disaggregated approaches in freight transport modelling in order to integrate more realistic freight agent behaviour. In contrast to aggregated models, disaggregated approaches are able to simulate the decision behaviour on the microlevel of an individual decision maker. In maritime container supply chains liner carriers or their brokers/agents and freight forwarders face a variety of interconnected logistical choices such as carrier, port, mode, route, shipment, or inventory choice. Modelling at least parts of these choices in disaggregated way could be of high value for adequate maritime hinterland policy development. This paper provides both an overview of present freight transport models with and without a logistics step and applied methods to study maritime supply chain freight agents' behaviour. A summarizing framework for behavioural freight transport modelling in maritime container supply chains is introduced. Finally, the framework is applied to a container freight transport model under development.
ACRYLAMIDE AND MOLECULAR OXYGEN FLUORESCENCE QUENCHING AS A PROBE OF SOLVENT‐ACCESSIBILITY OF AROMATIC FLUOROPHORES COMPLEXED WITH DNA IN RELATION TO THEIR CONFORMATIONS: CORONENE‐DNA AND OTHER COMPLEXES

Abstract— The relationships between the accessibilities to fluorescence quenchers (O2 and acrylamide) of three different aromatic molecules and their modes of binding to double‐stranded DNA were investigated. Proflavin was selected for this study because it is a known intercalator, while Hoechst 33258 is known to bind externally in the minor groove of DNA; it is shown here that the relatively bulky polycyclic aromatic hydrocarbon coronene forms partial intercalation complexes, and thus represents a third class of fluorophore‐DNA binding. Fluorescence quenching results suggest that Hoechst 33258 bound to DNA is fully accessible to 02, that the accessibility of partially intercalated coronene is reduced to 20% of the free‐solution value, while the accessibility of intercalated proflavin to molecular oxygen is at least ten times smaller than for free polycyclic aromatic molecules in fluid solutions. In contrast, the fluorescence of all these three fluorophores bound to DNA is insensitive to acrylamide (the effective accessibilities appear to be reduced by factors greater than 50 upon binding to DNA). It is concluded that O, is useful as a qualitative probe of the type of binding and solvent exposure of fluorophore‐DNA complexes, while acrylamide appears to be of limited utility. However, acrylamide fluorescence quenching may be useful for studies of other types of fluorophore‐DNA complexes since the fluorescence of the pyrene residues in covalent adducts derived from the binding of benzo(a)pyrene diol expoxide to DNA was found to be at least partially sensitive to acrylamide.
A systematic review of measures of activity limitation for children with cerebral palsy

This systematic review critically appraises the literature on the psychometric properties and clinical utility of evaluative activity limitation outcome measures used for children with cerebral palsy (CP). The search strategy yielded 29 articles for eight outcome measures that met the inclusion criteria for the review. The Gross Motor Function Measure and Activities Scale for Kids were found to have sound psychometric properties in most areas. Reliability was found to be adequate for all tools. For the CP population, further examination of some aspects of validity is required for the Child Health Questionnaire (CHQ), Functional Assessment Questionnaire (FAQ), Functional Mobility Scale (FMS), Pediatric Evaluation of Disability Inventory, Pediatric Outcomes Data Collection Instrument (PODCI), and the Functional Independence Measure for Children. The FAQ, CHQ, FMS, and PODCI were found to require further examination for responsiveness. Clinical utility of the measures varied. The FMS was the only one to differentiate between function in the home, school, and community and to consider different assistive devices. These findings suggest that a range of measures is required to evaluate activity, and assessment should be tailored to the individual needs of children with CP.
Impacts of fisheries on seabird communities

Long-line by-catch of albatrosses and petrels may soon lead to species extinctions. Set-net bycatch has caused major reductions in certain seabird populations. Some fisheries may decrease numbers of seabirds by reducing abundance of prey-fish. Other fisheries may increase seabird numbers, by increasing prey-fish abundance through depletion of predatory fish stocks, or by provision of offal and discards. These latter impacts of fisheries on seabirds are often difficult to measure against a background of many and varied environmental and human influences. Depletion of stocks of small lipid-rich fish have reduced numbers of seabirds, in Peru, the Norwegian Sea, and the Barents Sea. However, reductions of predatory fish stocks in the North Sea have more than compensated for quantities of sandeels removed by the sandeel fishery. While piscivorous fish stocks remain low, sandeel fishery and seabirds appear to be able to coexist. However, if piscivorous fish stocks recover in the North Sea, reduced availability of sandeels to seabirds may affect certain species. Provision of discards and offal can stimulate large increases in scavenging seabird numbers. Desirable reductions in discard rates may have an unfortunate side-effect of forcing some scavenging seabirds to turn to killing smaller seabirds, with drastic consequences for community structure.
Ex-post Evaluation of Mergers in the Supermarket Industry

In this paper we quantify the effects of horizontal mergers in the supermarket sector that took place in the US between 2003 and 2005. We contribute to the growing literature on ex-post merger evaluations in three ways: (1) we propose a cleaner identification strategy that results from the different event dates; (2) we quantify the effects on prices, but also on variety; (3) we show that the estimated effects exhibit heterogeneity and explain part of that heterogeneity with event characteristics. Our results indicate no effect on the average prices, but that total product variety in a store goes up by more than $$3\%$$3% following a merger. We find that the increase in variety after a merger is driven by stores that are not directly involved in the events, for whom the increase is larger than $$4\%$$4%.
Density Gradient Enrichment of Escherichia coli Conditional msbA Mutants

ABSTRACT Insight into the mechanism of lipid transport to the outer membrane of gram-negative bacteria has been hampered by the lack of an effective genetic screen for defective mutants. This work demonstrates an enrichment of conditional mutants defective in lipopolysaccharide export by Ludox density gradient centrifugation and selection for detergent resistance. New temperature-sensitive mutants with lipid export defects were isolated with single missense mutations in msbA. The results demonstrate the power of this approach for the study of lipid export in Escherichia coli.
Identification and functional analysis of a potential key lncRNA involved in fat loss of cancer cachexia

Cancer cachexia is a devastating, multifactorial, and irreversible syndrome characterized by skeletal muscle reduction with or without fat loss. Although much attention has been focused on muscle wasting, fat loss may occur earlier and accelerate muscle wasting in cachexia. The cause of 20% of cancer related death makes it urgent to discover molecular mechanisms behind cancer cachexia. Here we applied weighted gene co‐expression network analysis (WGCNA) to identify cachexia related gene modules using differentially expressed 3289 genes and 59 long non‐coding RNAs based on microarray data of cachectic and non‐cachectic subcutaneous adipose tissue. Subsequently, 16 independent modules were acquired and GSAASeqSP Toolset confirmed that black module was significantly associated with fat loss in cancer cachexia. Top 50 hub‐genes in black module contained only one lncRNA, VLDLR antisense RNA 1 (VLDLR‐AS1). We then explored the function of black module from the view of VLDLR‐AS1‐connected genes in the network. GO enrichment and KEGG pathways analysis revealed LDLR‐AS1‐connected genes were involved in Wnt signaling pathway, small GTPase mediated signal transduction, epithelial‐mesenchymal transition and so on. Through construction of competing endogenous RNAs (ceRNAs) regulation network, we showed that VLDLR‐AS1 may function with hsa‐miR‐600 to regulate gene GOLGA3, DUSP14, and UCHL1, or interact with hsa‐miR‐1224‐3p to modulate the expression of gene GOLGA3, ZNF219, RNF141, and CALU. After literature validation, we predicted that VLDLR‐AS1 most likely interacted with miR‐600 to regulate UCH‐L1 through Wnt/β‐catenin signaling pathway. However, further experiments are still required to validate mechanisms of VLDLR‐AS1 in fat reduction of cancer cachexia.
A Benefit-Cost Analysis of a Red Drum Stocking Program 1

Recreational saltwater anglers in the US mid-Atlantic states through the Gulf of Mexico commonly target the red drum, Sciaenops ocellatus. Due to concerns about the overharvesting within South Carolina (SC) coupled with regional management actions, SC has been exploring the technical feasibility of stocking juvenile red drum as a technique to augment the abundance of SC stock along with existing fishing regulations (e.g., daily creel limits). In 2005, a mail survey was used to collect selected socioeconomic data for estimating and extrapolating the potential economic benefits and funding of an SC red drum stocking program. Willingness to pay for red drum stocking was elicited by mailing a self-administered questionnaire to a random sample of SC saltwater license holders. The use of a hypothetical tax check-off payment vehicle is used to estimate the non-market economic value of a stocking program. Using a standard exante benefit-cost analysis approach, benefits are compared to estimated, explicit stocking costs. We find that the stocking program is economically efficient.
