Combined Electric and Acoustic Stimulation of the Auditory System: Results of a Clinical Study

Combined electric and acoustic stimulation (EAS) of the auditory system is a new therapy for patients with severe to profound high- and mid-frequency hearing loss but remaining low-frequency hearing. In a prospective study, 13 patients with low-frequency hearing of better than 60 dB below 1 kHz were implanted with a MED-EL COMBI 40+ cochlear implant. Pure tone thresholds as well as monosyllabic word scores and Hochmair-Schulz-Moser sentences in quiet and in noise were measured with hearing aids, cochlear implant alone and in the combined stimulation mode (EAS) in the same ear. Hearing could be partially preserved in 11 out of the 13 patients. All patients scored significantly higher with cochlear implant alone than with hearing aids. Seven patients scored higher in the EAS mode than with cochlear implant alone for sentences in noise, 4 remained unchanged, and 2 could not use EAS. Synergistic effects of EAS were most prominent for hearing in noise with increases of up to 72% as compared to cochlear implant alone.
Public Financing into Build-Operate-Transfer Hospital Projects in Italy

AbstractAn empirical analysis is presented to investigate the factors that have significant influence on the share of public financing into the total initial investment required to develop build-operate-transfer (BOT) health-care projects. Based on a model describing the main risks associated with public participation in BOT projects, a linear regression analysis has been conducted on a data set of Italian BOT hospital projects to yield implications. Outcomes reveal that the size of investment, the financial strength of the concessionaire, the duration of the concession period, the number of services, and the level of borrowing of the local health-care granting agency are significant factors of the level of public funding. The study confirms that public funding is provided not only to cover the non-self-financing portion of investment but also as a way to undertake a project in periods of scarce public financial resources. The methodology may be useful to refine the decision criteria for determining the l.
Iceland, the Farallon slab, and dynamic topography of the North Atlantic

Upwelling or downwelling flow in Earth's mantle is thought to elevate or depress Earth's surface on a continental scale. Direct observation of this "dynamic topography" on the seafloor, however, has remained elusive because it is obscured by isostatically supported topography caused by near-surface density variations. We calculate the nonisostatic topography of the North Atlantic by correcting seafloor depths for lithospheric cooling and sediment loading, and find that seafloor west of the Mid-Atlantic Ridge is an average of 0.5 km deeper than it is to the east. We are able to reproduce this basic observation in a model of mantle flow driven by tomographically inferred mantle densities. This model shows that the Farallon slab, currently in the lower mantle beneath the east coast of North America, induces downwelling flow that deepens the western North Atlantic relative to the east. Our model also predicts dynamic support of observed topographic highs near Iceland and the Azores, but suggests that the Icelandic high is due to local upper-mantle upwelling, while the Azores high is part of a plate-scale lower-mantle upwelling to the south. An anomalously deep area off the coast of Nova Scotia may be associated with the downwelling component of edge-driven convection at the continental boundary. Thus, several of the seafloor's topographic features can only be understood in terms of dynamic support from flow in Earth's mantle.
The Low-Diversity Fecal Microbiota of the Critically Endangered Kākāpō Is Robust to Anthropogenic Dietary and Geographic Influences

The critically endangered kākāpō, an herbivorous parrot endemic to New Zealand, is subject to intensive management to increase its population size. Key aspects of the management program include supplementary feeding and translocation of kākāpō between different predator-free islands to optimize the genetic composition of the breeding populations. While these practices have helped boost the kākāpō population, their impact on the kākāpō fecal microbiota is uncertain. Previous studies have found that the kākāpō possesses a low-diversity fecal microbiota, typically dominated by Escherichia/Shigella spp. However, the question of whether the low diversity of the kākāpō fecal microbiota is an inadvertent consequence of human interventions has yet to be investigated. To that end, we used high-throughput Illumina sequencing of 16S rRNA gene amplicons obtained from fecal material of 63 kākāpō representing different diets, islands, and ages. Remarkably, neither supplementary feeding nor geographic location were associated with significant differences in the overall fecal microbial community structures of adult kākāpō, suggesting that the kākāpō's low-diversity fecal microbiota is both inherent to this species and robust to these external influences.
TRAWL: Protection against rogue sites for the masses

The number of smartphones reached 3.4 billion in the third quarter of 2016 [1]. These devices facilitate our daily lives and have become the primary way of accessing the web. Although all desktop browsers filter rogue websites, their mobile counterparts often do not filter them at all, exposing their users to websites serving malware or hosting phishing attacks. In this paper we revisit the anti-phishing filtering mechanism which is offered in the most popular web browsers of Android, iOS and Windows Phone. Our results show that mobile users are still unprotected against phishing attacks, as most of the browsers are unable to filter phishing URLs. Thus, we implement and evaluate TRAWL (TRAnsparent Web protection for alL), as a cost effective security control that provides DNS and URL filtering using several blacklists.
Equal or Value Weighting? Implications for Asset-Pricing Tests

Does the choice of weighting scheme used to form test portfolios influence inferences drawn from empirical tests of asset pricing? To answer this question we first show that, with monthly rebalancing, an equal-weighted portfolio outperforms a value-weighted portfolio in terms of total mean return, four-factor alpha, and Sharpe ratio. We then explain that this outperformance is partly because the equal-weighted portfolio has higher exposure to systematic risk factors; but, a considerable part (42%) of the outperformance comes from the difference in alphas, which is a consequence of the rebalancing to maintain constant weights in the equal-weighted portfolio. Finally, we demonstrate that the inferences drawn from tests of asset-pricing models are substantially different depending on whether one uses equal- or value-weighted test portfolios. We illustrate this by considering four applications: (1) a test of the CAPM, using the methodology of Gibbons, Ross, and Shanken (1989); (2) a test of the spanning properties of the stochastic discount factor, using the approach of Hansen and Jagannathan (1991); (3) a test of the relation between characteristics and returns, using the multivariate weighted two-stage procedure of Fama and MacBeth (1973); and (4) a test of whether expected idiosyncratic volatility is priced or not, using the non-parametric methodology of Patton and Timmermann (2010). For all four tests, we explain how the weighting scheme influences our inferences.
Are Revisions to SFAS No. 5 Needed

SYNOPSIS: In the Financial Accounting Standards Board’s (FASB) project, “Disclosure of Certain Loss Contingencies,” a central issue underlying the debate is whether existing implementation of FASB Accounting Standards Codification Topic 450-20 (previously Statement of Financial Accounting Standards No. 5) provides sufficient and timely information to financial statement users. The Exposure Draft explains that constituents’ assertions of inadequate disclosures are the primary motive underlying the FASB’s re-examination of this issue (see, for example, page v of the Exposure Draft). However, little actual data are available to indicate the extent of the alleged problem. This manuscript presents the results of a study undertaken to provide such data. For a sample of litigation-related losses, we find a surprisingly large incidence of non-disclosure of contingent losses that cannot be readily explained. Moreover, even where there is disclosure, we find many cases where firms do not provide estimates of expect.
Water Allocation Mechanisms: Principles and Examples

From the earliest times, water resources have been allocated on the basis of social criteria -maintaining the community by ensuring that water is available for human consumption, for sanitation, and for food production. Societies have invested capital in infrastructure to maintain this allocation. Yet social change, including changes in (and more understanding of) how goods are distributed, has produced new issues in water allocation. Population growth has made water scarcity a major problem in many countries and water pollution, while by no means a recent problem, is more widespread than ever before. Traditionally the state has played a dominant role in managing water resources, but inefficient use of water, poor cost recovery for operating and maintenance expenses, the mounting cost of developing new water sources, and problems with the quality of service in agency-managed systems has led to a search for alternatives that make water allocation and management more efficient. The authors address some of the basic principles of treating water as an economic good and of allocating it among the sectors. After outlining the economic principles behind allocating scarce water resources, they review the actual means of various mechanisms used for allocating water, including marginal cost pricing, social planning, user-based allocation, and water markets. Giving examples from experience in several countries, they weigh the pros and cons of different approaches to water allocation, showing that no single approach is suitable for all situations. Clearly that state must play an important regulatory role, for example, but how effectively it does so depends on the relative political influence of various stakeholders and segments of society. User-based allocation is generally more flexible than state allocation, but collective action is not equally effective everywhere; it is most likely to emerge where there is strong demand for water and a history of cooperation. The outcome of market allocation depends on the economic value of water for various uses, but moving toward tradable property rights in water may ease the process of intersectoral reallocation by compensating the"losers"and creating incentives for efficient water use in all sectors.
Deal or No Deal, that is the Question: The Impact of Increasing Stakes and Framing Effects on Decision-Making Under Risk

In this paper, we utilize data from the Australian version of the TV game show, ‘Deal or No Deal’, to explore risk aversion in a high real stakes setting. An attractive feature of this version of the game is that supplementary rounds may occur which switch the decision frame of players. There are four main findings. First, we observe that the degree of risk aversion generally increases with stakes. Second, we observe considerable heterogeneity in people's willingness to bear risk – even at very high stakes. Third, we find that age and gender are statistically significant determinants of risk aversion, while wealth is not. Fourth, we find that the reversal of framing does have a significant impact on people's willingness to bear risk.
An Analysis of Substitution Bias in Measuring Inflation, 1959-85

The authors analyze the substitution bias in Laspeyres-type price indexes, using 101 c ommodities. They construct the tightest theoretical bounds on the cos t-of-living index using nonparametric methods and also construct supe rlative price indexes. Using nonparametric methods, the authors find homothetic preferences are consistent with the data. Sensitivity test s indicate that this result is not vacuous. Under this hypothesis, th e bias is between 0.22 and 0.14 percent per year. Superlative indexes imply a bias of about 0.18 percent. This estimate is somewhat larger than found in earlier studies. Commodity aggregation is found to be a major contributor to measured substitution bias. Copyright 1988 by The Econometric Society.
Recurrent fuzzy neural computation: Modeling, learning and application

A novel recurrent neurofuzzy network is developed in this paper. The network model is composed by two strucutres: a fuzzy system and a neural network. The fuzzy system contains fuzzy neurons modeled using t-norms and s-norms. The neural network is composed by nonlinear elements placed in series with the fuzzy system. The network model implicitly encodes a fuzzy rule-based system and its recurrent multilayered structure performs fuzzy inference. The topology induces a clear relationship between the network structure and the associated fuzzy rule-based system. Network learning involves three main steps. The first step uses a modified vector quantization approach to granulate the input universes. The next step assembles the network connections and their initial, randomly chosen weights. The third step uses two main paradigms to update the network weights: gradient descent and gradient projection method. The recurrent fuzzy neural network is particularly suitable to model nonlinear dynamic systems and to learn sequences. Computational experiment with a classic prediction problem benchmark shows that the fuzzy neural model outperforms a finite impulse response neural network.
Political connections, ownership structure and private-equity placement decision: evidence from Chinese listed firms

In contrast with many other countries, Chinese listed firms must obtain approval to make private-equity placements (PEPs) from the Chinese Security Regulatory Commission (CSRC), a state bureau that regulates capital market financing. We analyse the role of political connection (PC) and ownership structures when accessing private equity (PE) market, while investigating the mechanisms through which political ties operate within the regulatory process of PEPs. The findings suggest that PCs do not contribute to the firm’s decision to apply for PEPs, but firms with state-ownership demonstrate a higher propensity to apply for PEPs. PC and state-ownership appear to help firms to obtain approval from the CSRC, and these firms are treated more favourably than their rivals without such connections. Politically connected firms spend less time in managing bureaucracy, but PC and state-ownership negatively affect proceeds from the PE market in China. Firms with politically connected directors with professional business backgrounds tend to spend less time managing the CSRC, and these professionals positively affect proceeds from the PE market in China. This study provides important insights for policy-makers, investors, PE issuing firms and security market regulators.
Dielectric charging by AFM in tip-to-sample space mode: overview and challenges in revealing the appropriate mechanisms

The study of charge distribution on the surface and in the bulk of dielectrics is of great scientific interest because of the information gained on the storage and transport properties of the medium. Nevertheless, the processes at the nanoscale level remain out of the scope of the commonly used diagnostic methods. Atomic force microscopy (AFM) is currently applied for both injection and imaging of charges on dielectric thin films at the nanoscale level to answer the increasing demand for characterization of miniaturized components used in microelectronics, telecommunications, electrophotography, electrets, etc. However, the mechanisms for dielectric charging by AFM are not well documented, and an analysis of the literature shows that inappropriate mechanisms are sometimes presented. It is shown here that corona discharge, frequently pointed out as a likely mechanism for dielectric charging by AFM in tip-to-sample space mode, cannot develop in such small distances. Furthermore, a review of different mechanisms surmised to be at the origin of dielectric charging at the nanoscale level is offered. Field electron emission enhanced by thermionic emission is identified as a likely mechanism for dielectric charging at the nanoscale level. Experimental validation of this mechanism is obtained for typical electric field strengths in AFM.
Arc shifting method for small displacement measurement with quadrature CW doppler radar

The accuracy of physiological displacement measurement with CW Doppler radar is affected by the performance of DC offset cancellation. This paper presents an arc shifting approach to improve Levenberg-Marquardt (LM) method that is widely used for such calibration. The LM method becomes less accurate when measured displacement is very small with respect to carrier wavelength. An experiment was conducted to measure displacements of 2 mm and 1 mm using 2.4 GHz quadrature continuous wave (CW) Doppler radar, which demonstrated at least 35% improvement in accuracy when arc shifting method is applied.
A Psychogeriatric Assessment Program. I. Social Functioning and Ward Behavior †

Eighty newly admitted psychogeriatric patients were intensively investigated by a variety of disciplines — medical, laboratory, and psychologic‐psychiatric tests, including a Minimal Social Behavior Scale and an Integrative Social Functioning Scale. The sample of patients and methods of study for this 10‐month Geriatric Assessment Program are described. Assessment of present and past social functioning revealed good agreement between ratings made by different staff members. A decline in social functioning with time differentiated organic from functional psychiatric illness. Some of the scales employed may be of value for social screening purposes in the community.
Water and Energy Price Impacts on Residential Water Demand in Copenhagen

While water price effects on residential water demand have been studied for several decades, the impact of energy prices does not seem to have received much attention. In this paper a residential water demand function-derived from a model of household production of final consumption goods taking water, energy, and an aggregate of other goods as inputs-is estimated on pooled time series data. We find negative energy cross-price elasticities around -0.2 and water price elasticities in the order of -0.1 or smaller.
Infrared inhibition of embryonic hearts

Abstract. Infrared control is a new technique that uses pulsed infrared lasers to thermally alter electrical activity. Originally developed for nerves, we have applied this technology to embryonic hearts using a quail model, previously demonstrating infrared stimulation and, here, infrared inhibition. Infrared inhibition enables repeatable and reversible block, stopping cardiac contractions for several seconds. Normal beating resumes after the laser is turned off. The block can be spatially specific, affecting propagation on the ventricle or initiation on the atrium. Optical mapping showed that the block affects action potentials and not just calcium or contraction. Increased resting intracellular calcium was observed after a 30-s exposure to the inhibition laser, which likely resulted in reduced mechanical function. Further optimization of the laser illumination should reduce potential damage. Stopping cardiac contractions by disrupting electrical activity with infrared inhibition has the potential to be a powerful tool for studying the developing heart.
Source Packet Routing in Networking (SPRING) Problem Statement and Requirements

The ability for a node to specify a forwarding path, other than the normal shortest path, that a particular packet will traverse, benefits a number of network functions. Source-based routing mechanisms have previously been specified for network protocols but have not seen widespread adoption. In this context, the term "source" means "the point at which the explicit route is imposed"; therefore, it is not limited to the originator of the packet (i.e., the node imposing the explicit route may be the ingress node of an operator's network). This document outlines various use cases, with their requirements, that need to be taken into account by the Source Packet Routing in Networking (SPRING) architecture for unicast traffic. Multicast use cases and requirements are out of scope for this document.
The profitability‐risk tradeoff of just‐in‐time manufacturing technologies

Qualitative survey studies and a recent quantitative study by Callen et al. (2000) indicate that JIT manufacturing is more profitable than conventional non-JIT manufacturing. This study tests the hypothesis that the excess profitability of JIT manufacturing just compensates for the additional operational risks of JIT technology relative to conventional manufacturing. An often-suggested alternative hypothesis is that JIT manufacturing dominates conventional manufacturing in reducing costs and increasing revenues and that risk is not an issue. The multivariate results unambiguously reject the hypothesis that excess JIT profits are compensation for additional risk. We find that profitability is inversely related to risk, especially for JIT plants. We also find that the JIT plants in our sample are more profitable than non-JIT plants even after adjusting for risk, consistent with the dominance argument. Copyright © 2003 John Wiley & Sons, Ltd.

The amino acid sequences of the carboxyl termini of human and mouse hepatic lipase influence cell surface association Published, JLR Papers in Press, April 16, 2003. DOI 10.1194/jlr.M200374-JLR200

Human hepatic lipase (hHL) mainly exists cell surface bound, whereas mouse HL (mHL) circulates in the blood stream. Studies have suggested that the carboxyl terminus of HL mediates cell surface binding. We prepared recombinant hHL, mHL, and chimeric proteins (hHLmt and mHLht) in which the carboxyl terminal 70 amino acids of hHL were exchanged with the corresponding sequence from mHL. The hHL, mHL, and hHLmt proteins were catalytically active using triolein and tributyrin as substrates. In transfected cells, the majority of hHLs bound to the cell surface, with only 4% of total extracellular hHL released into heparin-free media, whereas under the same conditions, 61% of total extracellular mHLs were released. Like mHL, hHLmt showed decreased cell surface binding, with 68% of total extracellular hHLmt released. To determine the precise amino acid residues involved in cell surface binding, we prepared a truncated hHL mutant (hHL471) by deleting the carboxyl terminal five residues (KRKIR). The hHL471 also retained hydrolytic activity with triolein and tributyrin, and showed decreased cell surface binding, with 40% of total extracellular protein released into the heparin-free media. These data suggest that the determinants of cell surface binding exist within the carboxyl terminal 70 amino acids of hHL, of which the last five residues play an important role.
