Impact of Frequency-Domain Optical Coherence Tomography Guidance for Optimal Coronary Stent Implantation in Comparison With Intravascular Ultrasound Guidance

Background— Frequency-domain optical coherence tomography (FD-OCT) is a novel, high resolution intravascular imaging modality. Intravascular ultrasound (IVUS) is a widely used conventional imaging modality for achieving optimal stent deployment. The aim of this study was to evaluate the impact of FD-OCT guidance for coronary stent implantation compared with IVUS guidance. Methods and Results— A total of 70 patients with de novo coronary artery lesions and either unstable or stable angina pectoris were enrolled in this randomized study (optical coherence tomography [OCT] group: n=35, IVUS group: n=35). In the OCT group, stent implantation was performed under FD-OCT guidance alone and final stent expansion was evaluated by IVUS. In the IVUS group, conventional IVUS guidance was used and final stent apposition was evaluated by FD-OCT. There were no significant differences regarding the procedural, fluoroscopy time, and contrast volume. Although device and clinical success rates also were similar, the visibility of vessel border was significantly lower in the OCT group (P<0.05). Minimum and mean stent area and focal and diffuse stent expansion were smaller (6.1±2.2 mm versus 7.1±2.1 mm, 7.5±2.5 versus 8.7±2.4 mm, 64.7±13.7% versus 80.3±13.4%, 84.2±15.8% versus 98.8±16.5%, P<0.05, respectively), and the frequency of significant residual reference segment stenosis at the proximal edge was higher in the OCT group (P<0.05). Incomplete apposed struts in both groups were similar (P=0.34). Conclusions— FD-OCT guidance for stent implantation was associated with smaller stent expansion and more frequent significant residual reference segment stenosis compared with conventional IVUS guidance.
Integrating Transcriptome and Genome Re-Sequencing Data to Identify Key Genes and Mutations Affecting Chicken Eggshell Qualities

Eggshell damages lead to economic losses in the egg production industry and are a threat to human health. We examined 49-wk-old Rhode Island White hens (Gallus gallus) that laid eggs having shells with significantly different strengths and thicknesses. We used HiSeq 2000 (Illumina) sequencing to characterize the chicken transcriptome and whole genome to identify the key genes and genetic mutations associated with eggshell calcification. We identified a total of 14,234 genes expressed in the chicken uterus, representing 89% of all annotated chicken genes. A total of 889 differentially expressed genes were identified by comparing low eggshell strength (LES) and normal eggshell strength (NES) genomes. The DEGs are enriched in calcification-related processes, including calcium ion transport and calcium signaling pathways as reveled by gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis. Some important matrix proteins, such as OC-116, LTF and SPP1, were also expressed differentially between two groups. A total of 3,671,919 single-nucleotide polymorphisms (SNPs) and 508,035 Indels were detected in protein coding genes by whole-genome re-sequencing, including 1775 non-synonymous variations and 19 frame-shift Indels in DEGs. SNPs and Indels found in this study could be further investigated for eggshell traits. This is the first report to integrate the transcriptome and genome re-sequencing to target the genetic variations which decreased the eggshell qualities. These findings further advance our understanding of eggshell calcification in the chicken uterus.
Combined Rate and Precoder Design for Slow Fading Correlated MIMO Channels with Limited Feedback

The knowledge of channel state information at the transmitter (CSIT) is very important to enhance the spectral efficiency of MIMO links through precoder and power adaptation. In practice, only limited CSIT knowledge is usually available. In most existing works, the focus was on the precoder and power adaptation design for i.i. d. MIMO channels to optimize the ergodic capacity or SNR. The issues of rate adaptation and spatial correlation between antennas, which plays a key role in the overall system performance in slow fading channels, has been ignored in the existing works. In this paper, we shall propose an integrated framework for the rate and precoder adaptation under limited feedback for slow and spatially correlated MIMO fading channels. To capture the effects of potential packet errors, we consider average system goodput, which measures the b/s/Hz successfully delivered to the receiver, as our performance measure. The average system goodput is maximized subject to a total transmit power constraint and a target frame error rate (FER) constraint. Simulation results show our integrated design outperforms the Grassmannian precoder design in i.i. d. and spatially correlated MIMO channels. Furthermore, the limited feedback efficiency increases as the correlation coefficient increases.
Photocatalytic Properties of g-C3N4–TiO2 Heterojunctions under UV and Visible Light Conditions

Graphitic carbon nitride (g-C3N4) and titanium dioxide (TiO2) were chosen as a model system to investigate photocatalytic abilities of heterojunction system under UV and visible light conditions. The use of g-C3N4 has been shown to be effective in the reduction in recombination through the interaction between the two interfaces of TiO2 and g-C3N4. A simple method of preparing g-C3N4 through the pyrolysis of melamine was employed, which was then added to undoped TiO2 material to form the g-C3N4–TiO2 system. These materials were then fully characterized by X-ray diffraction (XRD), Brunauer Emmett Teller (BET), and various spectroscopic techniques including Raman, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), diffuse absorbance, and photoluminescence analysis. Photocatalysis studies were conducted using the model dye, rhodamine 6G utilizing visible and UV light irradiation. Raman spectroscopy confirmed that a composite of the materials was formed as opposed to a mixture of the two. Using XPS analysis, a shift in the nitrogen peak to that indicative of substitutional nitrogen was detected for all doped samples. This is then mirrored in the diffuse absorbance results, which show a clear decrease in band gap values for these samples, showing the effective band gap alteration achieved through this preparation process. When g-C3N4–TiO2 samples were analyzed under visible light irradiation, no significant improvement was observed compared that of pure TiO2. However, under UV light irradiation conditions, the photocatalytic ability of the doped samples exhibited an increased reactivity when compared to the undoped TiO2 (0.130 min−1), with 4% g-C3N4–TiO2 (0.187 min−1), showing a 43.9% increase in reactivity. Further doping to 8% g-C3N4–TiO2 lead to a decrease in reactivity against rhodamine 6G. BET analysis determined that the surface area of the 4% and 8% g-C3N4–TiO2 samples were very similar, with values of 29.4 and 28.5 m2/g, respectively, suggesting that the actual surface area is not a contributing factor. This could be due to an overloading of the system with covering of the active sites resulting in a lower reaction rate. XPS analysis showed that surface hydroxyl radicals and oxygen vacancies are not being formed throughout this preparation. Therefore, it can be suggested that the increased photocatalytic reaction rates are due to successful interfacial interactions with the g-C3N4-doped TiO2 systems.
Crowdsourcing for healthcare resource allocation

Heart diseases, pneumonia, and tuberculosis remain among the leading causes of mortality in the Philippines, diseases that can be easily prevented through proper medical care [3]. However, in the Philippines, there is still inequity in the access to healthcare resources across socioeconomic groups [3], [8]. This paper discusses how crowdsourcing can be utilized in the resource allocation for healthcare support, creating a venue for potential donors to contribute. During platform design phase, certain issues are encountered during the study such as healthcare information security, patient privacy, donation management, crowd motivation, implementation of microdonation, and sustainability. In this study, we design a system, WeSave, taking into consideration each of these issues.
Black Holes in Galaxy Mergers: Evolution of Quasars

Based on numerical simulations of gas-rich galaxy mergers, we discuss a model in which quasar activity is tied to the self-regulated growth of supermassive black holes in galaxies. The nuclear inflow of gas attending a galaxy collision triggers a starburst and feeds black hole growth, but for most of the duration of the starburst, the black hole is "buried," being heavily obscured by surrounding gas and dust, limiting the visibility of the quasar, especially at optical and ultraviolet wavelengths. As the black hole grows, feedback energy from accretion heats the gas and eventually expels it in a powerful wind, leaving behind a "dead quasar. " Between the buried and dead phases, there is a window in time during which the galaxy would be seen as a luminous quasar. Because the black hole mass, radiative output, and distribution of obscuring gas and dust all evolve strongly with time, the duration of this phase of observable quasar activity depends on both the waveband and imposed luminosity threshold. We determine the observed and intrinsic lifetimes as a function of luminosity and frequency, and calculate observable lifetimes ~10 Myr for bright quasars in the optical B band, in good agreement with empirical estimates and much smaller than our estimated black hole growth timescales ~100 Myr, naturally producing a substantial population of buried quasars. However, the observed and intrinsic energy outputs converge in the IR and hard X-ray bands as attenuation becomes weaker and chances of observation greatly increase. We also obtain the distribution of column densities along sight lines in which the quasar is seen above a given luminosity, and find that our result agrees remarkably well with observed estimates of the column density distribution from the SDSS for the appropriate luminosity thresholds. Our model reproduces a wide range of quasar phenomena, including observed quasar lifetimes, intrinsic lifetimes, column density distributions, and differences between optical and X-ray samples, having properties consistent with observations across more than 5 orders of magnitude in bolometric luminosity from 109 to 1014 L☉ (-17 ≲ MB ≲ -30).
The Influence Of Outsourcing Models On Vendor Knowledge Integration

ð ð Abstract ð In this paper, we attempt to address the role of outsourcing models (Global Delivery, Global Shared- services, and Build-Operate-Transfer Models) - on vendor knowledge integration, i.e., the understanding of the project requirements and client needs by the vendor. Specifically, the paper examine (a) what is the role of team identification, project complexity, and infrastructure diversity in vendor knowledge integration? , and (b) How does the type of outsourcing model moderate the respective relationships of team identification, project complexity, and infrastructure diversity with vendor knowledge integration? Theories of Social Exchange and a Knowledge-Based view are utilized. Using a sample of 66 randomly selected outsourced software development clients, we show that Team Identification and Infrastructure Diversity influence Vendor Knowledge Integration, which then influences project success. Further, use of appropriate outsourcing model has a moderating effect on the relationship of independent on the outcome of Information System Development projects. ð
Proteolysis of Fodrin (Non-erythroid Spectrin) during Apoptosis (*)

Several recent studies have implicated proteases as important triggers of apoptosis. Thus far, substrates that are cleaved during apoptosis have been elusive. In this report we demonstrate that cleavage of α-fodrin (non-erythroid spectrin) accompanies apoptosis, induced by activation via the CD3/T cell receptor complex in a murine T cell hybridoma, ligation of the Fas (CD95) molecule on a human T cell lymphoma line and other Fas-expressing cells, or treatment of cells with staurosporine, dexamethasone, or synthetic ceramide. Furthermore, inhibition of activation-induced apoptosis by pretreatment of T hybridoma cells with antisense oligonucleotides directed against c-myc also inhibited fodrin proteolysis, confirming that this cleavage process is tightly coupled to apoptosis. Fodrin cleavage during apoptosis may have implications for the membrane blebbing seen during this process.
Pilot study of Iyengar yoga for management of aromatase inhibitor‐associated arthralgia in women with breast cancer

Dear Editor, Aromatase inhibitors (AIs) are used routinely as part of adjuvant therapy for postmenopausal women with estrogen receptor positive breast cancer. Although beneficial, AIs are not without side effects. In addition to increased risk of osteoporosis and bone fracture, their use is associated with an arthralgia syndrome characterized by joint pain and stiffness. Other common symptoms attributed to AIs include fatigue, sleep problems, hot flashes, and mood disturbance. There has been limited research, to date, on treatment of AI-associated arthralgia as demonstrated by the lack of evidence-based clinical practice guidelines for its management. The possibility of relieving AI-associated joint pain with yoga has drawn attention. Initial supportive evidence comes from a randomized trial of yoga for 37 early stage breast cancer patients experiencing hot flashes that included 22 women prescribed AIs [1]. Significant reductions in joint pain were reported post-intervention and three months later relative to a wait-list condition. Additional support comes from a trial focused on yoga for AI-associated joint pain [2]. Participants were 10 breast cancer patients who reported worst joint pain severity ≥3 on a 0–10 scale. In a single-arm study, significant improvements over time were evident on performance-based measures of balance and flexibility and patient-reported outcomes (PROs) of perceived disability, pain severity, and quality of life. This study sought to gather additional preliminary data about the acceptability, feasibility, and potential efficacy of yoga for relief of AI-associated joint pain and to address the lack in the previous single-arm study of PROs assessing other common symptoms attributable to AIs.

Local Hand Control for Tezpur University Bionic Hand Grasping

Tezpur University (TU) Bionic Hand is a biomimetic extreme upper limb prosthesis. The Hand is intended to emulate grasping operations involved during 70% of daily living activities and have been developed using a biomimetic approach. This paper focus on the development of a local hand control for grasping by TU Bionic Hand. Grasp primitives: finger joint angular positions and joint torques are derived through kinematic and dynamic analysis. TU Bionic Hand emulates the grasp types following the dynamic constraints of human hand. The joint angle trajectories and velocity profiles of the Hand finger are in close approximation to those of the human finger.
Significance of vomiting after head injury

OBJECTIVES To determine whether the presence and severity of post-traumatic vomiting can predict the risk of a skull vault fracture in adults and children. METHODS Data were analysed relating to a consecutive series of 5416 patients including children who presented to an emergency service in the United Kingdom during a 1 year study period with a principal diagnosis of head injury. Characteristics studied were age, sex, speed of impact, level of consciousness on arrival, incidence of skull fracture, and the presence and severity of post-traumatic vomiting. RESULTS The overall incidence of post-traumatic vomiting was 7% in adults and 12% in children. In patients with a skull fracture the incidence of post-traumatic vomiting was 28% in adults and 33% in children. Post-traumatic vomiting was associated with a fourfold increase in the relative risk for a skull fracture. Nausea alone did not increase the risk of a skull fracture and multiple episodes of vomiting were no more significant than a single episode. In patients who were fully alert at presentation, post-traumatic vomiting was associated with a twofold increase in relative risk for a skull fracture. Skull fracture in the presence of nausea or vomiting: published research. CONCLUSION These results support the incorporation of enquiry about vomiting into the guidelines for skull radiography. One episode of vomiting seems to be as significant as multiple episodes.
Coronary CT and the Coronary Calcium Score, the Future of ED Risk Stratification?

Accurate and efficient evaluation of acute chest pain remains clinically challenging because traditional diagnostic modalities have many limitations. Recent improvement in non-invasive imaging technologies could potentially improve both diagnostic efficiency and clinical outcomes of patients with acute chest pain while reducing unnecessary hospitalizations. However, there is still controversy regarding much of the evidence for these technologies. This article reviews the role of coronary artery calcium score and the coronary computed tomography in the assessment of individual coronary risk and their usefulness in the emergency department in facilitating appropriate disposition decisions. The evidence base and clinical applications for both techniques are also described, together with cost- effectiveness and radiation exposure considerations.
Optimal HDA Schemes for Transmission of a Gaussian Source Over a Gaussian Channel With Bandwidth Compression in the Presence of an Interference

We consider transmission of a Gaussian source over a Gaussian channel under bandwidth compression in the presence of an interference known only to the transmitter. We study hybrid digital-analog (HDA) joint source-channel coding schemes and propose two novel layered coding schemes that achieve the optimal mean-squared error (MSE) distortion. This can be viewed as the extension of results by Wilson [“Joint Source Channel Coding With Side Information Using Hybrid Digital Analog Codes,” IEEE Trans. Inf. Theory, vol. 56, no. 10, pp. 4922-2940, Oct. 2010], originally proposed for sending a Gaussian source over a Gaussian channel in two cases: 1) Matched bandwidth with known interference only at the transmitter and 2) bandwidth compression where there is no interference in the channel. As the main contribution of this work, we provide optimal power allocation strategies for the proposed HDA schemes which enable us to cancel the channel interference and obtain the “optimum performance theoretically attainable” (OPTA) of additive white Gaussian noise (AWGN) channel with no interference in the case of bandwidth compression. We also provide performance analysis in the presence of signal-to-noise ratio (SNR) mismatch where we expect that HDA schemes perform better than strictly digital schemes.
Efficient Activation of Reconstructed Rat Embryos by Cyclin-Dependent Kinase Inhibitors

Background Over the last decade a number of species, from farm animals to rodents, have been cloned using somatic cell nuclear transfer technology (SCNT). This technique has the potential to revolutionize the way that genetically modified animals are made. In its current state, the process of SCNT is very inefficient (<5% success rate), with several technical and biological hurdles hindering development. Yet, SCNT provides investigators with powerful advantages over other approaches, such as allowing for prescreening for the desired level of transgene expression and eliminating the excess production of undesirable wild-type animals. The rat plays a significant role in biomedical research, but SCNT has been problematic for this species. In this study, we address one aspect of the problem by evaluating methods of activation in artificially constructed rat embryos. Principal Findings We demonstrate that treatment with a calcium ionophore (ionomycin) combined with a variety of cyclin-dependent kinase inhibitors is an effective way to activate rat embryos. This is in contrast to methods developed for the mouse embryo, which tolerates much less specific chemical treatments. Methods developed to activate mouse embryos do not translate well to rat embryos. Conclusions Activation methods developed for one species will not necessarily translate to another species, even if it is closely related. Further, the parthenogenic response to chemical activators is not always a reliable indicator of how reconstructed embryos will react to the same activation method. A better understanding of rat oocyte physiology, although essential for developing better models of disease, may also provide insights that will be useful for making the SCNT process more efficient.
Compound road environment recognition method using camera and laser range finder

In this paper a road environment recognition method for intelligent vehicle systems is introduced. This is done in order to increase safety since road environment is a complex problem. We introduce the ongoing results of our obstacle classification based on sensor merging using camera and laser range finder sensors. Firstly, a laser-camera calibration is performed. Secondly, objects are extracted using a clustering method in the LRF, then labeled as a pedestrian, vehicle or a bigger object. Thirdly, a verification method is implemented using a combination of histogram of oriented gradients and support vector machines. The experimental results prove the effectiveness of the proposed method for real time applications.
An Efficient and Secure User Authentication Scheme with Anonymity in Global Mobility Networks

User authentication is a very important securitymechanism for accessing the services while roaming in theglobal mobility networks. However, the authentication schemesdesigned are vulnerable to the attacks, hence new requirementsshould be employed while designing a scheme. In 2014 Gopeand Hwang proposed an efficient mutual authentication andkey agreement scheme, in which they stated that the schemeprovides a strong security to the user anonymity. In this paperwe have proved that Gope and Hwang scheme is vulnerableto stolen smart card attack, offline password guessing attack, forgery attack and replay attack. Moreover their scheme failsto preserve user anonymity. Hence a new efficient and secureuser authentication scheme with anonymity in global mobilitynetworks is proposed. Furthermore, the security analysis of theproposed scheme is also presented in this paper. Performanceanalysis shows that the proposed scheme is secure and suitablefor practical implementation.
Microscopic magnetic and high-frequency properties of a stress sensor using FeCoBSi magnetostrictive thin films

Magnetoelastic thin films are applied in remote interrogatable high-frequency devices. Integrated LC circuits operating at a frequency of 350 MHz are demonstrated. Due to the incorporation of the magnetic thin films, their inductance is sensitive to the applied external stress. A demonstrator was built, allowing a visualization of the effect of tensile and compressive strain on the device response. A comparison of the demonstrator measurement with high-frequency properties and the domain structure of the magnetoelastic layer proves an efficient integration of the magnetic material. The differences between predicted and measured device performance are related to an additional local stress distribution inside the magnetic device thus leading to an inhomogeneous stress and a locally varying magnetic anisotropy distribution. The investigations are essential for future applications of the devices as strain gauges or torque sensors.
