BEMD and assisted knowledge based meteorological facsimile map enhancement

An enhancement algorithm for weather fax map with zero-mean Gaussian noise is proposed based on BEMD and self features of meteorological facsimile maps. First decompose the noised meteorological facsimile map to IMF1 and a residue, then estimate the variance of the noise via BEMD and IMF1 through the intrinsic relation between the variances of IMF1 and the noise. According to the current time and location of the ship and the frequency loaded in the meteorologic electrograph, the type and the geographic information of the meteorological facsimile map is obtained. Then the noised map subtracts the geographic information after map matching. Last perform non-local mean filtering and binary value optimization on key words and marks to obtain the refined map. Experiments prove that the proposed algorithm has better performance for the enhancement of meteorological facsimile maps.
The Risk Level of Viet Nam Medicine and Medical Equipment Industries Under Financial Leverage During and After The Global Crisis 2007-2009

Purpose- This research paper evaluates the impacts of external financing on market risk for the listed firms in the Vietnam medical industry as it becomes necessary, esp. after the financial crisis 2007-2009. Design/methodology/approach- First, by using quantitative and analytical methods to estimate asset and equity beta of total 10 listed companies in Viet Nam medical industry with a proper traditional model. Second, we used three scenarios. Finally, leverage changed in three scenarios. Findings- We found out that the beta values, in general, for many institutions are acceptable. Under 3 different scenarios of changing leverage (in 2011 financial reports, 30% up and 20% down), we recognized that the risk level, measured by equity and asset beta mean, decreases when leverage increases to 30% and it increases in case leverage down to 20%. Third, by changing leverage in 3 scenarios, we recognized the dispersion of risk level, measured by equity beta var, increases if the leverage increases to 30%. Compared to the results of other industries, we see that asset beta var in here increases when leverage up to 30% as well as that in consumer good industry. Originality/value- Finally, this paper provides some outcomes that could provide companies and government more evidence in establishing their policies in governance.

Heparin-Conjugated PCL Scaffolds Fabricated by Electrospinning and Loaded with Fibroblast Growth Factor 2

A biodegradable poly(ε-caprolactone) (PCL) was synthesized by ring-opening polymerization of ε-caprolactone catalyzed by Sn(Oct)2/BDO, followed by the heparin conjugation using EDC/NHS chemistry. The structure of the heparin–PCL conjugate was characterized by 1H-NMR and GPC. The results of static contact angle and water uptake ratio measurements also confirmed the conjugation of heparin with the polyester. Its in vitro anticoagulation time was substantially extended, as evidenced by activated partial thromboplastin time (APTT) testing. Afterwards the conjugate was electrospun into small-diameter tubular scaffolds and loaded with Fibroblast Growth Factor 2 (FGF2) in aqueous solution. The loading efficiency was assayed by enzyme-linked immunosorbent assay (ELISA); the results indicated that the conjugate holds a higher loading efficiency than the blank polyester. The viability of released FGF2 was evaluated by MTT and cell adhesion tests. The amount and morphology of cells were significantly improved after FGF2 loading onto the electrospun heparin–PCL vascular scaffolds.
Multi-Objective Coordinated Planning of Distributed Generation and AC/DC Hybrid Distribution Networks Based on a Multi-Scenario Technique Considering Timing Characteristics

With increased direct current (DC) load density and the penetration of a large number of distributed generation (DG) units in alternating current (AC) distribution networks (DNs); a planning approach that considers transforming some of the AC lines into DC lines and building the DC network is proposed. Considering the DG output uncertainty and the load fluctuation, a planning model for an AC/DC hybrid distribution network (DN) with the DG based on the construction of multi-scenario technology with timing characteristics is built. In the DG configuration planning model, the lines to be transformed into DC form the access location and the decision regarding the DC or AC form of the newly built lines are considered optimizing variables. The DG investment, the network and converters of the DG and load, the active power loss and the voltage stability are considered in the objective functions. An improved adaptive niche genetic algorithm based on the fuzzy degree of membership and variance weighting is used to solve the nested model. Finally, considering the improved electrical and electronic engineers 33 (IEEE33) node system as an example, the correctness and effectiveness of the proposed planning method are verified. Compared to the plan without transforming some of the AC lines into DC lines and building a DC network, more DG can be admitted, and the economic cost of the AC/DC hybrid DN is notably decreased when planning to transform some of the AC lines into DC lines and build a DC network. The active power network loss and the voltage stability index are similarly further optimized.
Massive transient pulmonary air embolism during transvenous pacemaker implantation: potentially lethal but avoidable complication

A 71-year-old male patient presented to us with a history of repeated episodes of syncope. On evaluation, he was found to have complete heart block, for which we decided to go ahead with transvenous dual chamber pacemaker implantation. We went ahead with the extrathoracic subclavian venous puncture for endocardial lead insertion. Once the lead was introduced via the 7 F peel away sheath, patient had sudden onset of respiratory distress with desaturation. On fluoroscopy we noticed massive amount of air inside the right ventricular outflow tract and pulmonary artery (figure 1 and video 1) suggestive of iatrogenic air embolism. Opening and …
The $p$ -Sphere Encoder: Peak-Power Reduction by Lattice Precoding for the MIMO Gaussian Broadcast Channel

A vector precoding scheme has been recently proposed for the multiple-input multiple-output (MIMO) Gaussian broadcast channel. This technique minimizes the instantaneous transmitted power of linearly precoded signals, but does not take into account the peak-to-average-power ratio (PAPR). In this paper, we present a modified vector precoding scheme, where a perturbation vector is chosen in order to take into account both the instantaneous power and the instantaneous peak power of the transmitted signal. This is obtained by minimizing the p-norm of the transmitted signal for pges2. For this reason, the scheme is referred to as the p-sphere encoder. We demonstrate the performance of the proposed scheme applied to a MIMO independent, identically distributed Rayleigh fading downlink channel with simple channel inversion. We show that by choosing pges2, the proposed p-sphere encoder yields a tradeoff between power efficiency, PAPR reduction, and complexity. In particular, with eight antennas, the proposed algorithm significantly reduces the tail of the PAPR distribution, with very small degradation in terms of bit-error rate with respect to standard vector precoding
Left ventricular pressure-volume relationships during normal growth and development in the adult rat--studies in 8- and 50-week-old male Wistar rats.

AIMS Left ventricular (LV) pressure-volume relations provide relatively load-independent indexes of systolic and diastolic LV function, but few data are available on pressure-volume relations during growth and development in the normal adult heart. Furthermore, to quantify intrinsic ventricular function the indexes should be normalized for heart weight. However, in many studies the indexes are reported in absolute terms, or body weight-correction is used as a surrogate for heart weight-correction. METHODS We determined pressure-volume relations in young (8-week-old, n = 13) and middle-aged (50-week-old, n = 19) male Wistar rats in relation to their heart and body weights. The animals were anaesthetized and a 2F pressure-conductance catheter was introduced into the LV to measure pressure-volume relations. RESULTS Heart and body weights were significantly higher in the 50-week-old rats, whereas the heart-to-body weight ratio was significantly lower (2.74 +/- 0.32 vs. 4.41 +/- 0.37 mg g(-1), P < 0.001). Intrinsic systolic function, quantified by the slopes of the end-systolic pressure-volume relation (E(ES)), the dP/dt(MAX) vs. end-diastolic volume relation (S-dP), and the preload recruitable stroke work relation (PRSW), normalized for heart weight, was slightly decreased in the 50-week-old rats (S-dP: -6%, P < 0.004; PRSW: -3%, P < 0.06). Heart weight-corrected diastolic indexes were not significant different. The absolute indexes qualitatively showed the same results, but body-weight corrected pressure-volume indexes showed improved systolic function and significantly depressed diastolic function. CONCLUSIONS Intrinsic systolic function slightly decreases from the juvenile to the middle-aged period in normal male Wistar rats. Furthermore, correction of pressure-volume indexes for body weight is not an adequate surrogate for heart weight-correction in these animals.
The MINDS Method

As technology innovation rapidly changes service experiences, service designers need to leverage technology and orchestrate complex service systems to create innovative services while enabling seamless customer experiences. Service design builds upon contributions from multiple fields, including management, information technology, and interaction design. Still, more integration to leverage the role of technology for service innovation is needed. This article integrates these two service design perspectives, management and interaction design, into an interdisciplinary method—the Management and INteraction Design for Service (MINDS). Using a design science research approach, MINDS synthesizes management perspective models, which focus on creating new value propositions and orchestrating multiple service interfaces, with interaction design perspective models, which focus on technology usage and its surrounding context. This article presents applications of the MINDS method in two different service industries (media and health care) to demonstrate how MINDS enables creating innovative technology-enabled services and advances interdisciplinary service research.
The area of spread solderability test use for roughness influence assessment

The article deals with the influence of surface roughness on solderability. The area of spread test was used as a method for solderability measurement. For this measurement, test samples made from substrates for printed circuit boards, small solder balls, and two soldering technologies – vapor-phase and reflow soldering - were used. These technologies have been used because of similarity with the industrial process of soldering. The subjects of examination and comparison were wetting angle and expanse of melted solder on the surface. The paper presents results and conclusions from solderability testing of printed circuit boards with various surface roughnesses. Other conclusion is comparison of several types of fluxes and their impact on solder wetting on roughened surface.
Altered crystal violet permeability and lytic behavior in antibiotic-resistant and -sensitive mutants of Neisseria gonorrhoeae

Wild-type, antibiotic-resistant and hypersensitive isogenic strains of Neisseria gonorrhoeae were studied for uptake of crystal violet, rates of autolysis, and response to lysozyme. Total uptake of crystal violet was similar in all strains at 0 C but varied significantly at 37 C. Mutation at the nonspecific resistance locus ery resulted in relative impermeability to crystal violet at 37 C, as compared to wild type. The penetration barrier to crystal violet at 37 C was overcome by addition of 5 mM ethylenediaminetetraacetic acid. Mutation at ery also resulted in reduced rates of autolysis and reduced sensitivity to high concentrations of lysozyme under conditions of divalent cation (Mg2+) depletion. In contrast, mutation at the nonspecific drug hypersensitivity locus env resulted in increased uptake of crystal violet at 37 C, due to increased binding of dye to crude envelope as well as increased penetration into cytoplasm. The env mutants were also more rapidly autolytic and more sensitive to lysozyme than wild type in the absence of Mg2+. These results suggest that the cell envelopes of ery mutants are more stable and less permeable and those of env mutants are less stable and more permeable than wild-type strains.
Entrepreneurial Orientation and International Performance: The Moderating Effect of Decision-Making Rationality

This research examines how entrepreneurial orientation (EO) influences international performance (IP) of the firm taking into account the moderating effect of decision-making rationality (DR) on the EO-IP association. Such an investigation is significant because it considers the interplay of strategic decision-making processes supported by the bounded rationality concept in the entrepreneurship field. Drawing from a study on activities of 216 firms in the United States and United Kingdom, the evidence suggests that DR positively moderates the EO-IP association. The findings suggest that managers can improve IP by combining EO with rational (analytical) processes in their strategic decisions.
Implementation of AHB bus protocol for system on chip security

A set of design methodologies and experiments related to enabling hardware systems to utilize on-the-fly configuration of reconfigurable logic to recover system operation from unexpected loss of system function. Methods included programming using locally stored configuration bit stream as well as using configuration bit stream transmitted from a remote site. A specific ways of utilizing reconfigurable logic to regenerate system function, as well as the effectiveness of this approach as a function of the type of attack, and various architectural attributes of the system. Based on this analysis, proposed architectural features of System-on-Chip (SOC) that can minimize performance degradation and maximize the likelihood of seamless system operation despite the function replacement. This approach is highly feasible in that it is not required to specially manage system software and other normal system hardware functions for the replacement.
A pilot trial of neuropsychological evaluations conducted via telemedicine in the Veterans Health Administration.

INTRODUCTION Many veterans live in rural areas distant from Veterans Affairs Medical Centers (VAMCs) and receive primary medical care from community-based outpatient clinics (CBOCs). These veterans often must travel great distances to the nearest VAMC for neuropsychological evaluations, resulting in poor access to care, travel reimbursement costs, fee-basis evaluations of uncontrolled quality, and driving safety concerns. Return trips for feedback compound complications. Accordingly, we initiated a pilot trial of neuropsychological evaluation and feedback via telemedicine (i.e., clinical videoconferencing). SUBJECTS AND METHODS Participants were veterans referred for neuropsychological evaluation from a rural CBOC 115 miles from the regional VAMC. All veterans were given the choice to undergo evaluation at the CBOC via telemedicine or in-person at the VAMC. Telemedicine equipment allowed presentation of digitized material with simultaneous patient observation. Testing materials were organized in numbered folders and given to veterans by CBOC clerks immediately prior to evaluation. Clerks returned completed materials via facsimile. RESULTS Fifteen veterans from the rural CBOC were seen for neuropsychological evaluation. Eight chose telemedicine evaluation. Groups based on evaluation modality appeared similar on demographics, referral basis, resulting neuropsychiatric diagnoses, and follow-through on recommendations. No significant technical or clinical difficulties were encountered, and veterans reported satisfaction with telemedicine. All veterans requested feedback via telemedicine. CONCLUSIONS Neuropsychological evaluation via telemedicine is feasible and appears comparable to in-person evaluation. Experiences are encouraging and consistent with the broader literature on the acceptance of and satisfaction with clinical videoconferencing. Future studies will assess possible psychometric issues in clinical populations.
Outbound Open Innovation for Enhanced Innovation Performance: An Empirical Study based on BTB Enterprises in China

Open Innovation gains a wide spread attention in technology management research in recent years. Because existing research about the relationship between outbound open innovation and innovation performance is limited and context factors are ignored in existing research and based on Chesbrough’s open innovation model and theory of enterprise competence, this study introduces enterprise competence and knowledge spillovers into the field of outbound open innovation, explores their moderated roles between open innovation and innovation performance. We use high-tech firms as research sample to test the hypothesis that we proposed and find that: (1) outbound open innovation has a positive effect on innovation performance; (2) both enterprise competence and knowledge spillovers moderate the relationship between outbound open innovation and innovation performance. These conclusions have important implications for the development and application of open innovation theory.
Investigation of the textile structures with different design used in electromagnetic shielding

This paper describes a study on the development of few textile structures and the possibility to use them in electromagnetic shielding and protection equipment manufacturing. The long-term exposure to electromagnetic waves can seriously damage a person's health. The goal of this research is: to evaluate the implementation possibilities of new materials and composite structure (using amorphous magnetic materials, carbon powders stainless steel yarns and copper yarns), and also to achieve a protective composite textile material with absorbing properties, in order to protect human body and residential areas. Conductive materials have different absorption and reflection behaviors: metals are known for having high reflectivity, whereas carbon fibers and conductive polymers are known for having a high absorption behavior. This general trend was also observed in the results obtained. Conventional textile materials are not suitable for this purpose, but their modification and transformation in composites or other type of structures can be useful.
The development of large area saturable Bragg reflectors for the generation of widely-tunable ultra-short pulses

This thesis focuses on the realization of two photonic devices; 1) semiconductor lasers and 2) large area broadband Saturable Bragg Reflectors (SBRs). Semiconductor lasers explore the use of 3D and 2D quantum confinement of charge carriers within quantum dots (QD) and quantum wells (QW) lasers respectively. The index-guided QD and QW heterostructure lasers that were fabricated in this work investigate the electrical and optical properties of these active regions for the implementation in all-optical logic gates. Saturable Bragg Reflectors (SBRs) can be used for the generation of widely tunable ultra-short pulses for various laser systems. The III-V based SBRs comprise of layers, whose thicknesses correspond to the wavelength of the laser system that is to be mode-locked. To form short pulses, SBRs with broadband reflectivity and large area (hundreds of microns) are required. One of the key elements for the realization of broadband SBRs is the development of the thermal oxidation process that creates buried low index AlOY layers over large areas. The design, fabrication, characterization and implementation of ultra-broadband high index contrast III-V/AlOy SBRs as circular mesas, as well as inverted mesa structures for ultrashort pulse generation is presented using a physical model of the oxidation process.

Fractalkine (CX3CL1) and fractalkine receptor (CX3CR1) distribution in spinal cord and dorsal root ganglia under basal and neuropathic pain conditions

Fractalkine is a unique chemokine reported to be constitutively expressed by neurons. Its only receptor, CX3CR1, is expressed by microglia. Little is known about the expression of fractalkine and CX3CR1 in spinal cord. Given that peripheral nerve inflammation and/or injury gives rise to neuropathic pain, and neuropathic pain may be partially mediated by spinal cord glial activation and consequent glial proinflammatory cytokine release, there must be a signal released by affected neurons that triggers the activation of glia. We sought to determine whether there is anatomical evidence implicating spinal fractalkine as such a neuron‐to‐glia signal. We mapped the regional and cellular localization of fractalkine and CX3CR1 in the rat spinal cord and dorsal root ganglion, under basal conditions and following induction of neuropathic pain, employing both an inflammatory (sciatic inflammatory neuropathy; SIN) as well as a traumatic (chronic constriction injury; CCI) model. Fractalkine immunoreactivity and mRNA were observed in neurons, but not glia, in the rat spinal cord and dorsal root ganglia, and levels did not change following either CCI or SIN. By contrast, CX3CR1 was expressed by microglia in the basal state, and the microglial cellular concentration was up‐regulated in a regionally specific manner in response to neuropathy. CX3CR1‐expressing cells were identified as microglia by their cellular morphology and positive OX‐42 and CD4 immunostaining. The cellular distribution of fractalkine and CX3CR1 in the spinal circuit associated with nociceptive transmission supports a potential role in the mechanisms that contribute to the exaggerated pain state in these models of neuropathy.
