Patient-Activated Controlled Expansion for Breast Reconstruction Using Controlled Carbon Dioxide Inflation: Confirmation of a Feasibility Study

Background: Women with breast cancer or those at high risk of developing breast cancer because of familial history of the disease or genetic mutations are frequently indicated for therapeutic or prophylactic mastectomy. Prosthetic reconstruction of the breast with placement of tissue expanders followed by implants offers favorable aesthetic and psychological results while adding only minimal additional surgical intervention. This study describes the confirmatory phase of an earlier feasibility trial that involved seven women who successfully underwent patient-activated controlled expansion for breast reconstruction with 10 AeroForm patient-controlled tissue expanders. Methods: A prospective, open-label, single-arm, single-surgeon confirmatory study in Perth, Australia, evaluated outcomes of two-stage breast reconstruction using the investigational device. Each subject administered a preset 10-cc dose of carbon dioxide gas using a remote dosage controller, three times each day, with a 3-hour lockout between doses until full expansion was achieved. Results: Thirty-three women with breast cancer, family history, or predisposition because of the BRCA1 or BRCA2 gene mutation underwent pedicled latissimus dorsi flap procedures with placement of 61 carbon dioxide–based tissue expanders. The mean number of days for subjects to achieve desired expansion was 17 ± 5. Operating the dosage controller was described by the surgeon as very easy in 94 percent of the cases and by 97 percent of the subjects. No serious adverse events were reported. Conclusion: This study confirms that the AeroForm breast tissue expander has demonstrated the ability to provide, relative to saline expanders, a needle-free, patient-controlled, convenient, and time-saving method of tissue expansion. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
Losing Trust in Money Doctors

Delegated stock market participation is fragile, especially during crises. Investors who had delegated all of their equity investments to fund managers before the financial crisis were almost twice as susceptible to exiting the stock market during the crisis than their peers who invested in individual stocks, other things equal. This result holds across two very different samples: 40,000 clients at a large German bank and the 2007-2009 panel of the U.S. Survey of Consumer Finances. Households who reported to rely on the advice of money doctors before the crisis, but not afterwards, were especially likely to sell all their stock funds.
Community Dynamics of Bacteria in Sourdough Fermentations as Revealed by Their Metatranscriptome

ABSTRACT The lactic acid bacterial (LAB) community dynamics of two wheat and two spelt sourdough fermentations that were daily back-slopped were monitored during a period of 10 days by hybridizing time-related RNA samples, representing the metatranscriptome, to an LAB functional gene microarray. To indicate the species present in each hybridized sample, annotation information for the 2,269 oligonucleotides on the microarray was used. The overall hybridization data revealed that after a transition phase of 5 days, in which atypical sourdough LAB species, including Enterococcus species, were found, a stabilized ecosystem was established with Lactobacillus plantarum and Lactobacillus fermentum as the dominating LAB species. Compared with the combined outcome of culture-dependent and culture-independent identification techniques, the microarray data revealed a functional role for Lactococcus lactis in the early stage ecosystem and the dominance of Pediococcus pentosaceus in most of the fermentations, besides L. plantarum and L. fermentum. Consequently, metatranscriptome hybridization data obtained using an LAB functional gene microarray was shown to be an interesting alternative to microbiological analysis of the community dynamics of complex food ecosystems.

Firstly, the image is collected by the monocular camera, preprocessed, and then processed by an improved motion obstacle detection algorithm. Finally, the image is processed to solve the void problem and get the complete motion obstacle information. The experimental results show that the method proposed in this paper requires less computational complexity and simpler parameter design than the traditional detection algorithm, and the motion detection algorithm proposed in this paper can satisfy the real-time and real-time Accuracy requirements.
Trajectory Planning for a Mobile Robot

Robotics, when successfully carried out, is concerned with artifacts that optimize their own behavior in the light of information using sensors and actuators. The information includes both that which is stored and that which is immedi ately available from the sensors. In this paper the problem addressed is how the speed and the steer angle of a path curvature limited robot-vehicle, one that has to move in order to turn, may be altered in order to achieve desirable changes in its position and orientation. A kinematic description of both a tricycle and "turtle" vehicle architecture is developed. A comparison is made between the two architectures. The effect of modulating the steer angle of a path curvature limited vehicle, a tricycle, with a gaussian envelope is illustrated for various amplitudes of the gaussian and speed of the robot-vehicle. The effect of the time concat enation of the steer angle with two or more gaussian enve lopes shows that a range of activities relevant to the functional needs of a robot-vehicle are possible. A number of other "modulating" functions are identified, and it is suggested that these deserve further investigation.
Total Quality Management in Higher Education: Defenders, Opponents, and Attempts for Modifications

The purpose of this paper is to clearly present TQM principles and characteristics initiated by TQM founders and to review the literature that witnesses TQM success as well as failure in higher education and attempts to modify the TQM model to fit the higher education context. The higher education total quality management model and its impact on the university including professional autonomy and scholarly activities are examined in order to study its positive and negative effects.In order to understand TQM principles and its applicability or inapplicability to the higher education context, the TQM principles are studied as developed by the main TQM scholars. The founders of TQM basically initiated it in manufacturing, yet this paper studies this literature in order to give a comprehensive picture of TQM so as to make its principles clear for the sake of studying its implementation in higher education. This paper critically reviews the literature of TQM implementation in higher education, and this literature is divided among scholars who defend TQM in higher educationand scholars who argue that this management system cannot be applied in the public sector, and specifically in higher education.
Nickel hexayttrium decaiodide, [NiY6]I10

Comproportionation reactions of yttrium triiodide, yttrium and nickel led to the formation of the compound [NiY6]I10, which is isostructural with the prototypical [RuY6]I10. In particular, [NiY6]I10 is composed of isolated nickel centered yttrium octahedra (site symmetry -1) that are further surrounded by iodide ligands to construct a three-dimensional cluster complex framework. Although this compound has been previously detected by powder X-ray diffraction techniques [Payne & Corbett (1990 ▶). Inorg. Chem. 29, 2246–2251], details of the crystal structure for triclinic [NiY6]I10 were not provided.
BlastAlign: a program that uses blast to align problematic nucleotide sequences

UNLABELLED BlastAlign uses NCBI blastn to build a multiple nucleotide alignment and is intended for use with sequences that have large indels or are otherwise difficult to align globally. The program builds a matrix representing regions of homology along the sequences, from which it selects the 'most representative' sequence and then extracts the blastn query-anchored multiple alignment for this sequence. The matrix is printed and allows subgroups to be identified visually and an option allows other sequences to be used as the 'most representative'. The program contains elements of both Perl and Python and will run on UNIX (including Mac OSX) and DOS. An additional Perl program BlastAlignP uses tblastn to align nucleotide sequences to a single amino acid sequence, thus allowing an open reading frame to be maintained in the resulting multiple alignment.

Nuclear export, enlightened

The physicist Richard Feynman once quipped that the key to solving or making significant progress on a scientific problem was to “find the open channel. ” For the cell biological problem of nucleus-to-cytoplasm transport, the literal open channels have long been known: the nuclear pore complexes (NPCs). However, in the metaphorical sense as well, recent work has significantly “opened” the NPC channel as regards the biophysics of the engagement and transit of outward-bound cargo. In this issue of PNAS, Siebrasse et al. (1) track single molecules of a native messenger RNA and provide details on the approach of these transcripts to the NPCs, the probability and persistence of engagement, and the channel transit times. This impressive study was enabled by the use of an iconic system for tracking specific transcripts in the nucleus of a living cell, together with a recently developed innovation in the method of microscopy used.
Precise determination of h/me using a rotating, superconducting ring.

A precise determination of h/m/sub e/ (Planck's constant divided by the free-electron mass) using a rotating, superconducting ring is in progress. The measurement is based on flux quantization and the London moment: two manifestations of the macroscopic quantum nature of superconductivity. Here we report the first results from a precision, thin-film niobium ring. These data have a statistical error of 10 parts per million (ppm). A systematic error exists at the level of 2500 ppm, due to the presence of electric charge on the rotor. A model for the charge distribution is suggested and used to adjust the results and obtain a value of h/m/sub e/. This work has determined h/m/sub e/ directly to an accuracy of 100 ppm, a higher level of precision than previously reported. Recent theoretical calculations have predicted a relativistic mass increase of 150 ppm for electrons in superconducting niobium, but the uncertainty in our final results prevented the clear identification of this effect.
Empirical evidence on internal control disclosure in Italy Stock Exchange and Polish Stock Exchange

The vast academic research evidenced that corporate transparency has favorable effects on markets and on external stakeholder judgment and decision making (e.g. Lang, Lundholm, 1993). As an important part of corporate governance, voluntary disclosure on internal control system has received a great attention after the introduction of the COSO frameworks and the requirements of the US Sarbanes Oxley Act (SOX). The Italian Corporate Governance Code and the Polish Code of Best Practice ask to increase the disclosure on internal control system in order to give more information on the effectiveness and efficiency of the companies. Using content analysis we define an Internal Control Score Disclosure (ICSD) of the Italian Stock Exchange companies and of Polish Stock Exchange companies for the year 2013 in order to investigate corporate governance influence on internal control disclosure. The ICSD will be examined in order to provide empirical evidence for the significant increase in the disclosure level of internal control system and to test if, as Beeks and Brown (2006) stated, companies with better governance disclose more information, while those with a weak governance are lacking of financial disclosure and transparency. Preliminary findings show a clear relationship between ICSD and the dimension of board of directors. In next stages we will involve more years and, if possible, more companies. In the next development of the work we will also look for control on possible relationship between ICDS and companies' characteristics.
Does consumers' personal reciprocity affect future purchase intentions?

In this study, we examine the mediating role of a consumer's personal reciprocity in the relationships between brand trust, brand loyalty and product familiarity, and future purchase intentions. Data from 308 printer users in Hong Kong reveals that a consumer's personal reciprocity partially mediates the relationships between brand trust and brand loyalty, and future purchase intentions. The theoretical implication is that personal reciprocity not only enhances consumers' future purchase intentions but also provides an alternative path linking brand trust and brand loyalty to consumers' future purchase intentions. The managerial implication is that by capitalising on a consumer's personal reciprocity in the context of consumer-firm relationships, firms can improve their performance in retaining existing customers.
Investigation of the Propagation Induced Pulse Broadening (PIPB) Effect on Single Event Transients in SOI and Bulk Inverter Chains

The propagation of single event transients (SET) is measured and modeled in SOI and bulk inverter chains. The propagation-induced pulse broadening (PIPB) effect is shown to determine the SET pulse width measured at the output of long chains of inverters after irradiation. Initially, narrow transients, less than 200 ps at the struck inverter, are progressively broadened into the nanosecond range. PIPB is induced by dynamic floating body effects (also called history effects) in SOI and bulk transistors, which depend on the bias state of the transistors before irradiation. Implications for SET hardness assurance, circuit modelling and hardening are discussed. Floating body and PIPB effects are usually not taken into account in circuit models, which can lead to large underestimation of SET sensitivity when using simulation techniques like fault injection in complex circuits.
Comments on the Recently Reported Low Biological Effectiveness of Ultrasoft X Rays

In a recent paper, C. K. Hill et al. (1) reported the results of experiments carried out at the University of Wisconsin in which Chinese hamster V79 and mouse C3H 10T1⁄2 cells were irradiated with synchrotronproduced 273 eV and 860 eV ultrasoft X rays. X rays at these energies are heavily attenuated through a single mammalian cell. Therefore, they chose two energies that would be equally attenuated, enabling a direct comparison between the biological effectiveness of the two energies. The two main results of the cell survival experiments carried out by the Wisconsin group were: 1. The biological effectiveness for these two energies, for both cell lines, was similar. 2. After the mean nuclear dose was calculated, taking into account attenuation through the cells, there were no significant differences in cell survival between these two ultrasoft X-ray energies and 250 kVp X rays. Based on this second result, the Wisconsin group (1) concluded that, in general, ultrasoft X rays are no more biologically effective per unit dose than are standard orthovoltage X rays and g rays, and hence they refuted the suggestion (2, 3) that the majority of critical damage that follows exposure to standard X rays and g rays results from low-energy, secondary electrons. Their second result is inconsistent with previously published experimental data from several other groups, and it therefore warrants close scrutiny to understand the origin of this difference, especially in view of the recent increase in the use of ultrasoft X rays for radiobiology experiments. The first result mentioned above is not inconsistent with other published experimental data or with the main interpretations that have been suggested for a high biological effectiveness of ultrasoft X rays. We first briefly discuss Result 1, and then we consider in more detail some potential reasons for the difference of Result 2.
Magnetic resonance quantification of the myocardial perfusion reserve with a Fermi function model for constrained deconvolution.

The myocardial perfusion reserve, defined as the ratio of hyperemic and basal myocardial blood flow, is a useful indicator of the functional significance of a coronary artery lesion. Rapid magnetic resonance (MR) imaging for the noninvasive detection of a bolus-injected contrast agent as a MR tracer is applied to the measurement of regional tissue perfusion during rest and hyperemia, in patients with microvascular dysfunction. A Fermi function model for the distribution of tracer residence times in the myocardium is used to fit the MR signal curves. The myocardial perfusion reserve is calculated from the impulse response amplitudes for rest and hyperemia. The assumptions of the model are tested with Monte Carlo simulations, using a multiple path, axially distributed mathematical model of blood tissue exchange, which allows for systematic variation of blood flow, vascular volume, and capillary permeability. For a contrast-to-noise ratio of 6:1, and over a range of flows from 0.5 to 4.0 ml/min per g of tissue, the ratio of the impulse response amplitudes for hyperemic and basal flows is linearly proportional to the ratio of model blood flows, if the mean transit time of the input function is shorter than approximately 9 s. The uncertainty in the blood flow reserve estimates grows both at low (< 1.0 ml/min/g) and high (> 3-4 ml/min/g) flows. The predictions of the Monte Carlo simulations agree with the results of MR first pass studies in patients without significant coronary artery lesions and microvascular dysfunction, where the perfusion reserve in the territory of the left anterior descending coronary artery (LAD) correlates linearly with the intracoronary Doppler ultrasound flow reserve in the LAD (r = 0.84), in agreement with previous PET studies.
The Probabilistic Set-Covering Problem

In a probabilistic set-covering problem the right-hand side is a random binary vector and the covering constraint has to be satisfied with some prescribed probability. We analyze the structure of the set of probabilistically efficient points of binary random vectors, develop methods for their enumeration, and propose specialized branch-and-bound algorithms for probabilistic set-covering problems.
A study into the problems of cost control for construction projects

Cost control in the construction industry is to ensure that construction projects are completed within the budget of clients. From the perspective of contractors, understanding and awareness on the practices of cost control are important for them to control their cost for construction projects. In relation to cost control for construction projects, this study aims to identify problems in the practices of cost control and to suggest the strategies to overcome the problems. The method of questionnaire survey was applied to collect data for this study. Questionnaires were distributed to 115 CIDB-registered G7 contractors. The study concludes that changes of design, shortage of labours, inaccurate of quantity-take off, lack of cost information, lack of expertise, lack of knowledge and inaccurate of cost estimate are the main problems in cost control practices. The study proposes that providing cost control training to the staff, managing the inflation risk by allowing fluctuation of price in the contract, minimizing the changes in design and constantly update the cost data are the strategies to overcome problems in cost control practices for construction projects.

Novel H1N1 2009 influenza virus infection in Bangkok, Thailand:effects of school closures

Background: Influenza virus is the major cause of respiratory illness, especially in young and older age groups. Since 1918, many subtypes, defined by hemagglutinine (HA) and neuraminidase (NA), have caused global infections or pandemics. The recently isolated swine origin influenza virus (S-OIV) subtype H1N1 has been defined by the World Health Organization (WHO) as the cause of the present influenza pandemic. Objective: To describe and attempt to predict the epidemiology of the novel H1N1 2009 in Bangkok and to evaluate the effects of school closures during the outbreaks. Materials and methods: The first two human cases infected by this S-OIV subtype H1N1 or H1N1 2009 in Thailand have been reported in May 12, 2009 by the Ministry of Public Health. Between May 12 and July 30, 2009, 1212 nasopharyngeal (NP) swabs from four private hospitals and Chulalongkorn Hospital, Bangkok have been sent to a laboratory for Influenza virus diagnosis. The diagnosis was based on real time RT-PCR for seasonal influenza (H1, H3) and H1N1 2009. Results: One thousand two hundreds and twelve specimens of patients with influenza like illness were tested using real time RT-PCR detection. Between mid June and early July, the number of H1N1 2009 increased rapidly with a high prevalence among the 6- to 20-year olds. School closure policy, long public holiday, and additional preventive measures have led to a rapid reduction in the number of H1N1 2009 positive patients. Conclusion: Preventive measures including school closures are important to slow down the outbreak and thus enable health care centers to cope with the large number of patients. Everyone should play a role in delaying the spread of this pandemic.
