OCT in the evaluation of late stent pathology: restenosis, neoatherosclerosis and late malapposition

pathology Coronary stents were developed to overcome the limitations of percutaneous transluminal coronary angioplasty (PTCA), improving acute success, facilitating the management of complications (mainly coronary dissection and acute vessel closure) and lowering restenosis rates [1, 2]. However, PTCA and subsequent stent deployment are an aggression to the arterial wall and leave a metallic material that must be incorporated into the vascular structure through a complex restoration process called neointimal coverage or re-endothelialization. The ﬁ rst devices used were bare metal stents (BMSs). Pathological studies have suggested that re-endothelialization occurs with the development of neointimal tissue within the luminal area of stents, reaching an intimal hyperplasia peak from 6 to 12 months after BMS deployment [3]. After BMS deployment, in-stent restenosis (ISR) was still a relevant issue with rates up to 20% – 30%, due to excessive neointimal proliferation [1, 2]. Initial reports showed excellent late performance of these stents after the initial phase of higher risk ISR, with clinical stability of the stented site at 8 – 10 years after BMS implantation [4]. Therefore, ISR is generally considered to be a stable process, with an early peak in intimal hyperplasia followed by a quiescent period. However, there is emerging histological and clinical evidence of late de novo in-stent neoatherosclerosis [5 – 7]. These studies indicate that in some patients there is degenerative evolution of neointima into an unstable atherosclerotic lesion and that ISR should not always be regarded as a benign entity.
Evidence for an c(1S) - resonance in B0 c(1S) K+-decays c(1S) B0 c(1S) K+-

A Dalitz plot analysis of B 0 → η c ( 1 S ) K + π − decays is performed using data samples of pp collisions collected with the LHCb detector at centre-of-mass energies of √ s = 7 , 8 and 13 TeV, corresponding to a total integrated luminosity of 4 . 7 fb − 1 . A satisfactory description of the data is obtained when including a contribution repre-senting an exotic η c ( 1 S )π − resonant state. The signiﬁcance of this exotic resonance is more than three standard deviations, while its mass and width are 4096 ± 20 + 18 − 22 MeV and 152 ± 58 + 60 − 35 MeV, respectively. The spin-parity assignments J P = 0 + and J P = 1 − are both consistent with the data. In addition, the ﬁrst measurement of the B 0 → η c ( 1 S ) K + π − branching fraction is performed and gives B ( B 0 → η c ( 1 S ) K + π − ) = ( 5 . 73 ± 0 . 24 ± 0 . 13 ± 0 . 66 ) × 10 − 4 , where the ﬁrst uncertainty is statistical, the second systematic, and the third is due to limited knowledge of external branching fractions.
Analysis of Ringing Artifact in Image Fusion Using Directional Wavelet Transforms

—In the ﬁeld of multi-data analysis and fusion, image fusion plays a vital role for many applications. With inventions of new sensors, the demand of high quality image fusion algorithms has seen tremendous growth. Wavelet based fusion is a popular choice for many image fusion algorithms, because of its ability to decouple different features of information. However, it suffers from ringing artifacts generated in the output. This paper presents an analysis of ringing artifacts in application of image fusion using directional wavelets (curvelets, contourlets, non-subsampled contourlets etc.). We compare the performance of various fusion rules for directional wavelets available in literature. The experimental results suggest that the ringing artifacts are present in all types of wavelets with the extent of artifact varying with type of the wavelet, fusion rule used and levels of decomposition.
Experimental examination of films of gold nanoparticles on Si/SiO 2 substrate by ellipsometry

We have investigated optical properties of films of gold nanoparticles on Si/SiO 2 substrate by using the method of spectroscopic ellipsometry in dependence on morphology of the films. Different morphology of the films was obtained by flash-annealing at various temperatures of identical sputtered thin gold layers. Ellipsometric spectra were compared with account of pictures of the films obtained by scanned electron microscopy. Remarkable dependence of depolarization of the reflected light with the frequency of localized plasmon resonance versus the film morphology was found.
Operational Excellence through Process Improvement at a Public University

Operational excellence (OE) is not something new to the manufacturing and services; including private higher education institutions locally and abroad especially in the US, UK, Canada and the Scandinavian countries. However, for the public universities in Malaysia, it is something of a novelty. As the largest public university in Malaysia with more than 160,000 students, Universiti Teknologi MARA (UiTM) has taken the initiative to spearhead the operational excellence in the country’s higher education. Moreover, in the face of reduced funding from the government, UiTM must be responsive and transforms to become more process-centric as it is through operational excellence that strategic outcomes can be achieved. The aim of this paper is to investigate the implementation of operational excellence through process improvement by the university; its achievements; and challenges faced pertaining to the implementation. The university adopts the concepts of Lean and Six Sigma DMAIC approach to process improvement in its journey to achieve operational excellence. The process improvement data was recorded in an ‘Online Process Improvement Register’ (OPIR). Sofar, the university has been able to train 5.9% of its 18,188 staff in doing process improvement. The findings showed that as a result of doing improvement on some of its processes, the university has managed to save 48.99%on cost. Apart from that, the university has been able to reduce the time taken on the processes, the number of manpower needed for the processes, the number of complaints, and also improve customer satisfaction. Some of the challenges that have been identified during the implementation are department and staff engagement; inadequate manpower; and lack of knowledge on the part of some of the Quality Managers and OE Trainers.

NUMERICAL AND EXPERIMENTAL ANALYSIS OF STRUCTURAL DAMPING FOR BOLTED SPLICE CONNECTION JOINT

Summary: This paper presents the finite element modeling of bolted joints for structural dynamic analysis to achieve a reasonable accuracy in simulation results. Non-linear effects in splice connected joints involve normal compressive loads holding components together combined with dynamic lateral loads inducing some amount of shear slip in contact interaction between elements of splice connection joint. The complexities of the slip process are responsible for the nonlinear nature of the interfaces, both in terms of stiffness and dissipation. Exploring the physics of joints directly is not readily done because key interactions takes place at the interface of surfaces, where instrumentation cannot be placed without changing the problem. Consequences of the specific conditions of joint connections are increased dynamic problems related to vibrations and dissipative processes in structure connection joints. Structural joints are the main reason for the significant level of energy dissipation and source of structural damping. The aim of this paper is to present some problems regarding research of structural damping and the importance of study Contact Mechanics to better understand the problem of structural damping. torque for M8 and M6, 8.8 bolt quality, Table 1.

Institutional Knowledge at Singapore Management University Endogenous quality choice, signaling, and welfare

We consider a model in which each worker endogenously selects his own type through a private investment decision and selects a public signal in the labor market. Signaling then contributes to social welfare through its in(cid:135)uence on the quality choice. We o⁄er a rationale for the argument that there are too many high-type workers from a welfare perspective, identifying circumstances under which separating equilibrium generates too many high-type workers while having to use the incentive-compatible signal and treat high-type workers di⁄erently in the market. The ine¢ ciency can then be reduced in pooling equilibrium.
Femtosecond Laser-Assisted Cataract Surgery in Soft and Hard Nuclear Cataracts: A Comparison of Effective Phacoemulsification Time

Purpose: To compare effective phacoemulsification time (EFX) in femtosecond laser-assisted cataract surgery (FLACS) versus traditional quick chop phacoemulsification (QCP) in senile nuclear cataracts with different densities focusing on soft and hard ones. Patients and Methods: A prospective non-randomized comparative study was carried out in Al Watany Eye Hospital and Ain Shams University Hospital, Cairo, Egypt; 250 eyes with senile nuclear cataract (NC) were included and classified into two main groups, FLACS and QCP groups. Each of them was stratified according to nuclear density into three subgroups, subgroups I (Soft NC), II (Medium NC), and III (Hard NC). Sextans-softened fragmentation pattern was performed in the FLACS group. Total EFX utilized for nucleus disassembly and removal was recorded by the completion of each surgery. Results: A total of 117 eyes were included in the FLACS group and 133 eyes in the QCP group. No significant difference in EFX was observed between the two groups ( P = 0.228). Regarding subgroups, EFX showed no statistically significant difference between FLACS and QCP ( P = 0.283) in soft NC. For hard NC, a trend to lower values of EFX in FLACS compared with QCP was found, but without statistically significant difference ( P = 0.122). Only in medium NC were significantly lower values obtained in FLACS compared with QCP ( P < 0.0001). When compared with QCP technique, FLACS can be used for advantages aside from EFX reduction, including astigmatic keratotomies, accurate sizing, and centration of capsulotomies especially in hard and soft nuclear cataracts. Significant reduction of total EFX with FLACS is most prominent only in medium-density nuclear cataracts. softening patterns.
Trigeminal Neuralgia aches (TN) therapy with peripheral nerves signal actuation (PNS)

Iran. Abstract For people with Trigeminal Neuralgia (TN), It is a non-invasive advantage to use the peripheral nerves signal actuation (PNS) via skin and it is suitable even for people who suffering from the periodic Trigeminal nerve headaches with less intensity. It is a technical challenge to non-invasive cranial nerves actuation or nerves actuation through the head’s skin because it is hard to patients and makes a lot of pain for them. These nerves actuation increase endorphin generation, as a result, the patient’s pain tolerance limit will increase and this will prevent ache entry to neural system. This study is a clinical trial and the method is parallel trial that implemented on 50 hospitalization patients on neurology department of a hospital in Tehran. In this study, the pain intensity will be review and comparison on three modes; without electrical signal actuation; with low frequency electrical signal actuation (5Hz); and with high frequency electrical signal actuations (100Hz). There are one-way ANOVA (one way variance analysis), TUKEY and DUNNETT statistics tests to compare severity of pain average in several modes. The results showed significant differences between the patients who used peripheral nerves actuation (PNS) via skin before their headache or during headache (P<0.08) as the minimum pain, when use the high frequency electrical signal and maximum pain is without using of electrical signal actuations. But there are no significant differences in pain intensity when use the low frequency electrical signal (PERIOSTEUM) in nerves. Therefore, the patient can tolerant it and feel no
Micro-structuring of titanium collectors by laser ablation technique: a promising approach to produce micro-patterned scaffolds for tissue engineering applications

Multi-scale micro-structured scaffolds can sustain attachment and orientation of different cells phenotypes. An innovative use of laser ablation technique to build micro-structured titanium surfaces to be used as collectors in both electrophoretic deposition and electrospinning processes was investigated. To produce micro-patterned scaffolds, a negative replica patterning was exploited by designing specific patterns to be laser ablated on titanium plates. This method allows the deposition of the scaffolds on the mold, thus reproducing the micro-features on the scaffold surface. The titanium surface morphology depending on ablation parameters was studied and the capability of the process in replicating the micro- pat tern was characterized.
Mediator of Angiogenesis Junctional Adhesion Molecule-C Is a Soluble

Junctional adhesion molecule-C (JAM-C) is an adhesion molecule expressed by endothelial cells (ECs) that plays a role in tight junction formation, leukocyte adhesion, and transendothelial migration. In the current study, we investigated whether JAM-C is found in soluble form and whether soluble JAM-C (sJAM-C) mediates angiogenesis. We found that JAM-C is present in soluble form in normal serum and elevated in rheumatoid arthritis (RA) serum. The concentration of sJAM-C is also elevated locally in RA synovial ﬂuid compared with RA serum or osteoarthritis synovial ﬂuid. sJAM-C was also present in the culture supernatant of human microvascular ECs (HMVECs) and immortalized human dermal microvascular ECs, and its concentration was increased following cytokine stimulation. In addition, sJAM-C cleavage from the cell surface was mediated in part by a disintegrin and metalloproteinases 10 and 17. In functional assays, sJAM-C was both chemotactic and chemokinetic for HMVECs and induced HMVEC tube formation on Matrigel in vitro. Neutralizing anti–JAM-C Abs inhibited RA synovial ﬂuid–induced HMVEC chemotaxis and sJAM-C–induced HMVEC tube formation on Matrigel. sJAM-C also induced angiogenesis in vivo in the Matrigel plug and sponge granuloma models. Moreover, sJAM-C–mediated HMVEC chemotaxis was dependent on Src, p38, and PI3K. Our results show that JAM-C exists in soluble form and suggest that modulation of sJAM-C may provide a novel route for controlling pathological angiogenesis.

Predicting Populations 1

SYNOPSIS. Deterministic models are valuable for gaining insight into the mechanisms of population dynamics. However, they are not generally useful for the practical problem of estimating real populations. Herein we present a method for estimating the birth and death rates as well as the age structure for a population using only "aggregated" measurements such as total adult deaths and birthrates. The method applies to nonstationary popula- tions with nonlinear birth and deathrates.
CAD oriented frequency, temperature, and DC bias dependent small‐signal, scalable circuit model of parallel‐plate paraelectric varactors

Simple, CAD compatible small‐signal scalable circuit model for the thin film parallel‐plate ferroelectric varactors is reported. It is based on the measured permittivity and loss tangent of the ferroelectric films along with the fundamental theoretical relationships of ferroelectrics in paraelectric phase. The model makes use of the measured DC field (voltage) at the inflection point of the C‐V curve where the nonlinearity (dC/dV) and the tunability are maximum. Both the capacitance and the equivalent loss resistance (dielectric losses) in the ferroelectric film take into account the low permittivity layers at the boundaries of the nano‐columns of the film. The frequency dependent losses in the top and bottom plates of the varactors and the parasitic inductance of the plates are also taken into account. The model is valid for ferroelectric films having columnar structure. It is useful in wide temperature, DC field, and frequency ranges. © 2008 Wiley Periodicals, Inc.

Aircraft Image De-noising and Identification using Deep Neural Network

— Images corrupted during transmission and acquisition required de-noising for proper interpretation and reliable recognition. Though related traditional methods are known to be reliable in de-noising and identification, learning aided approaches have become popular recently. Subsequent, deep learning has been accepted to be an efficient mechanism and is found to be increasingly becoming integral element for a range of image processing and computer vision applications. This work deals with the formulation of a system based on Auto-encoder (AE) and Stacked Auto-encoder (SAE) configured for de-noising of certain military aircrafts as part of an automatic target recognition (ASR) system. The ASR is based on a class of classifiers that include the soft-max layer, conventional Artificial Neural Network (ANN) and Deep Neural Network (DNN) of the type convolutional neural network (CNN). The sample set includes five image types corrupted with Gaussian, Poisson, Speckle, Salt and Pepper noise for de-noising by AE and SAE topologies and identification by the CNN. Further, the image sets are subjected to signal to noise ratio (SNR) variation between -3 to 20 dB which increases the data volume for training which is necessary to make the system robust. Despite higher computational latency, the efficiency of the proposed approach is justified by the experimental results.
