Spectra and appearance of late gadolinium enhancement in magnetic resonance imaging of non-ischemic myocardial disease - from pattern to diagnosis

Objective: Value of late gadolinium enhancement (LGE) in diagnosis of ischemic disorders in cardiac magnetic resonance is well-known. The purpose of the present paper was to describe more details and characteristics of LGE patterns arising in several non-ischemic myocardial diseases. Methods: Cardiac MRI was performed in 1,905 patients at a 1.5-T MR system and showed LGE with 1,646/1,905 demonstrating LGE patterns or other diagnostic criteria (e.g. laboratory results, ECG, coronary angiography findings) regarded typical for ischemic heart disease. The remaining 259/1,905 patients revealed LGE related to non-ischemic myocardial disease. Two experts (radiologists and/or cardiologist) qualitatively described LGE pattern in consensus reading with regard to its site (left or right ventricle), extent (subendocardial, midmyocardial, subepicardial, transmural, pericardial), segment (according to the 17- segment model of left ventricle (LV)), distribution (streaky, patchy, punctual, spotty, crescent, diffuse), and intensity (weak, moderate, strong). Thereafter, results were correlated to final diagnosis based on synopsis of clinical features, laboratory results, ECG, biopsy, or other imaging procedures. Results: In 250/259 patients (96.5%) only the LV was affected by LGE, most frequently midmyocardial (166/259). In most cases this was due to peri-/myocarditis (especially if of weak-moderate intensity), while a weaker, streaky or spotty LGE basal or lateral pointed to HCM (39/166) and streaky and lateral to DCM (20/166). A midmyocardial, patchy LGE in segment 3 and 5 was caused by Fabry’s disease (6x). In case of a transmural, spotty or patchy pattern LGE pointed to HCM, if intensity was weak-moderate, or to peri-/myocarditis, when LGE was moderate-strong. In addition to that, subepicardial LGE in basal segments with patchy, streaky, or spotty distribution and moderate intensity was also due to peri-/myocarditis, while it was located midventricular, spotty and weak in TASH (transcoronary ablation of septum hypertrophy). Conclusions: Several LGE patterns point to certain non-ischemic myocardial diseases and thereby might facilitate and confine differential diagnosis and might be useful in biopsy planing.
Does Elderly Employment have an Impact on Youth Employment? A General Equilibrium Approach

Does an increase of elderly employment cause a decline in youth employment? A simplified view of a demand driven economy would give a positive answer to this question. Econometric studies based on a single equation approach deliver little support for this belief. However, these studies typically suffer from identification problems to which no attention is paid in most cases. We therefore use a general equilibrium framework when trying to quantify these effects. Using yearly and quarterly Austrian labor and gdp data, we estimate two model variants by Bayesian methods: a) a standard equilibrium model where the degree of complementarity between old, young and primary labor is crucial for the sign and strength of the relevant effects and b) a simple, solely demand driven model which always leads to a crowding out of young through an increase in employment of the old. It turned out that the demand driven model is inferior in fitting the data compared to the standard model. Further, the degree of complementarity is estimated to be strong enough to lead to a small positive effect of elderly employment on youth employment.
A stochastic model of gene switches

We present a stochastic model of genetic regulation where the expression of genes are controlled by protein levels. In particular, we examine a genetic toggle switch with two competing proteins where one protein switches off the other gene. We model this switching behaviour in the framework of the Stochastic Master Equation (SME), which is a continuous time variant of a Markov model used in chemical systems. Thus far, the SME is mainly solved by stochastic simulation due to the perceived high computational demands. We explore approximation techniques which allow the numerical solution of the SME to be tractable.
Spectral Domain Analysis of Gyrotropic Anisotropy Chiral Effect on the Input Impedance of a Printed Dipole Antenna

A theoretical analysis of a printed dipole antenna on a gyrotropic-anisotropy chiral dielectric substrate is presented. The study is based on numerical techniques for the characterization of electromagnetic propagation in chiral media. The general complex wave equation and the dispersion relation for such a medium are derived in the spectral domain. The spectral Green's function of a grounded dielectric chiral slab is developed, and the spectral domain moment method impedance matrix elements are calculated. The effect of the chiral gyrotropy element on the input impedance of a dipole antenna printed on a grounded chiral substrate is analyzed using the Galerkin-based Method of Moments.
Social support and health - related quality of life among older adults: a descriptive study

Background: Social support is presently receiving increased attention in health care. Many few studies investigated about the association of social support and health among elderly people in Iran. The purpose of the study was to ascertain if a relationship exists bet ween social support and health - related quality of life of older adults. Methods: This was a cross sectional study. The study participants were 180 elders aged 60 years and over living in Tehran, Iran. In addition to demographic information the Social Suppo rt Scale (SSS) and the Short Form Health Survey (SF - 36) were used to collect data. The data were analyzed in a descriptive fashion. Results: The findings showed a high level of perceived social support among older adults. The highest and lowest aspects of health - related quality of life derived from the SF - 36 were social functioning and physical functioning, respectively. Furthermore the results from Spearman test indicated that there were significant correlation between social support and all aspects of the SF - 36. The correlation between social support and vitality was the highest. Conclusion: The findings suggest that social support could play an important role in improving health - related quality of life of older adults.

Outcome of Macroeconomic Instability (A Case for Iran)

There is no unique threshold between stability and instability for each macroeconomic variable. Rather, there is a continuum of combinations of levels of key macroeconomic variables, including growth, inflation, fiscal deficit, current account deficit, and international reserves, that together can indicate macroeconomic instability. The combination of these factors can make it relatively easy to identify a country in a state of macroeconomic instability or stability. In this paper we investigate the macroeconomic instability and it's outcome in Iran by a self-made index and filtering algorithms ( KLR). The result shows that, in the years in which the macroeconomic instability has increased, the economic growth has been affected and decreased. It seems that the macroeconomic instability is a serious barrier against the economic growth of the country.
Cities Are Physical Too: Using Computer Vision to Measure the Quality and Impact of Urban Appearance

For social scientists, developing an empirical connection between the physical appearance of a city and the behavior and health of its inhabitants has proved challenging due to a lack of data on urban appearance. Can we use computers to quantify urban appearance from street-level imagery? We describe Streetscore: a computer vision algorithm that measures the perceived safety of streetscapes. Using Streetscore to evaluate 19 American cities, we find that the average perceived safety has a strong positive correlation with population density and household income; and the variation in perceived safety has a strong positive correlation with income inequality.
Reduction of near-inertial energy through the dependence of wind stress on the ocean-surface velocity

A realistic primitive-equation model of the Southern Ocean at eddying spatial resolution is used to examine the effect of ocean-surface-velocity dependence of the wind stress on the strength of near-inertial oscillations. Accounting for the ocean-surface-velocity dependence of the wind stress leads to a large reduction of wind-induced near-inertial energy of approximately 40 percent and of wind power input into the near-inertial frequency band of approximately 20 percent. A large part of this reduction can be explained by the leading-order modification to the wind stress if the ocean-surface velocity is included. The strength of the reduction is shown to be modulated by the inverse of the ocean-surface-mixed-layer depth. We conclude that the effect of surface-velocity dependence of the wind stress should be taken into account when estimating the wind-power input into the near-inertial frequency band and when estimating near-inertial energy levels in the ocean due to wind forcing.
Storm climate and related marine hazards in the Northeast Atlantic and the North Sea

Storms represent a major environmental threat. At sea, wind pushes water masses towards the coast where water levels may become dangerously high eventually overwhelming coastal defences and inundating low-lying coastal areas. Also, the sea-surface is affected where wind waves and swell are generated and obviously represent a threat to offshore navigation, shipping and coastal defence. We review a number of questions related to windstorms in the Northeast Atlantic and the North Sea, in particular: (1) How to determine decadal and longer variations in the storm climate? The methodological problem is that many variables suffer from inhomogeneities or are available for too short periods only. Proxies are suggested from which useful information can be derived. (2) How has the storm climate developed in the recent past? It is shown that an increase from about the 1960s has replaced a downward trend since about 1890. Storm activity is decreasing again since about 19901995. (3) How did storm surges and ocean waves develop in the recent past and what may happen in the expected course of anthropogenic climate change? The issue is examined using detailed regional reconstructions and climate change scenarios.
Preparation of graphene oxide stabilized nickel nanoparticles with thermal effusivity properties by laser ablation method

Nickel nanoparticles were dispersed uniformly in a graphene oxide solution, using a laser ablation technique with different ablation times that ranged from 5 to 20 minutes. The results indicate that the nickel nanoparticle sizes inside the graphene oxide decreased, and the volume fraction for the nickel nanoparticles in the graphene oxide increasedwith an increasing ablation time. Further, using Fourier Transform Infrared Spectroscopy, the nickel nanoparticles in the graphene oxide demonstrate greater stability from possible agglomeration when the nanoparticle was capped with oxygen from the carboxyl group of the graphene oxide. The thermal effusivity of the graphene oxide and nickel nanoparticle graphene oxide composite was measured using a photoacoustic technique. The concentration of graphene oxide shifted from 0.05mg/L to 2mg/L, and the thermal effusivity increased from 0. 153Wċs1/2ċcm-2ċK-1 to 0. 326Wċs1/2ċcm-2ċK-1. In addition, the thermal effusivity of the nickel nanoparticles graphene oxide composite increased with an increase in the volume fraction of nickel nanoparticles from 0. 1612Wċs1/2ċcm-2ċK-1 to 0. 228Wċs1/2ċcm-2ċK-1.

Innovation in Industrial Districts: Evidence from Italy

The aim of this paper is to show that Italian manufacturing firms belonging to Marshallian industrial districts carry out a higher innovative effort than is usually acknowledged. The empirical analysis makes use of a panel of 1,218 district and non‐district firms belonging to traditional sectors. Data refers to the years 1992 and 1995. We have estimated an augmented Cobb–Douglas production function. The estimates make it possible to empirically identify three different determinants of firms’ productivity: (i) the intentional innovative activity; (ii) the “district effect”; and (iii) the joint district and innovation effect. The results show that firms’ membership in industrial districts and product innovations are key factors in explaining the productivity of firms working in traditional Italian sectors.
Vemurafenib-sensitive and Vemurafenib-resistant human malignant melanoma cell lines. Results showed that coenzyme Q10 alone significantly reduced the viability and migration of human malignant melanoma cells. In addition, coenzyme Q10 alone inhibited the apoptosis induction in Vemurafenib-sensitive 

approved: ________________________________________________________ (Thesis Advisor Signature) Melanoma is a type of highly invasive skin cancer derived from melanocyte with a poor prognosis. Clinical studies have shown that the most common mutation in malignant melanoma is BRAFV600E. Vemurafenib (PLX4032) is a clinically approved targeted drug for BRAF mutant melanoma that has a high therapeutic efficiency and significantly prolongs overall survival rate. However, most patients will become drug resistant and suffer from melanoma relapse within one year. Antioxidants have been widely used as supplements for cancer prevention and decreasing the side effects of cancer therapy. However, antioxidants could also protect cancer cells from oxidative stress and promote cell growth. This study aims to examine the effect of coenzyme Q10 and β-carotene on cell growth and invasion, and on the cytotoxicity of Vemurafenib against both Vemurafenib-sensitive and Vemurafenib-resistant human malignant melanoma cell lines. Results showed that coenzyme Q10 alone significantly reduced the viability and migration of human malignant melanoma cells. In addition, coenzyme Q10 alone inhibited the apoptosis induction in Vemurafenib-sensitive SK-MEL-28 cells. β-carotene alone did not affect the viability and apoptosis induction of melanoma cells; however, it inhibited cell mobility and invasiveness. Coenzyme Q10 enhanced the ability of Vemurafenib to decrease viability and mobility of melanoma cells. In contrast, β-carotene alleviated the cytotoxicity of Vemurafenib and mitigated the inhibitory effect of Vemurafenib on cell viability, mobility and invasion. Both coenzyme Q10 and β-carotene protected melanoma cells from undergoing apoptosis induced by Vemurafenib. βcarotene enhanced the suppression of Ras-Raf-Mek-Erk intracellular signaling pathway activation, which may contribute its inhibitory effect on cell mobility and invasiveness. Therefore, since it increases the cytotoxicity of Vemurafenib, coenzyme Q10 can potentially serve as an adjunct used together with anti-melanoma chemotherapy. However, due to alleviating anti-melanoma activities of Vemurafenib, β-carotene may not be appropriate supplements for melanoma patients who concurrently receive Vemurafenib as a targeted therapy.
A new PDE based approach for image restoration and enhancement using robust diffusion directions and directional derivatives based diffusivities

This article proposes a novel, partial derivatives based filter, for oriented patterns filtering and enhancement. We propose a filtering and restoration process with a strong anisotropic behaviour. Locally, our filter uses a superposition of one-dimensional diffusion processes; in each pixel the diffusion directions are given by a principal component analysis, on these directions the processes behaviour is modulated by non-linear functions depending on the absolute values of the directional derivatives. Selectively, depending on these measures, the filter can act like a classical diffusion filter, simplifying the image, or it can produce edge and corner enhancement. The equation we propose is very general and it can be modified for specific image restoration tasks. Through applications samples we would show the efficiency of our method both on synthetic images and on real ones.
REMOVAL OF CADMIUM USING A NOVEL NANO COMPOSITE, SILICA AEROGEL, ACTIVATED CARBON

A novel composite adsorbent, Silica aerogel activated carbon was synthesized by sol-gel process at ambient pressure drying method. The composite was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and Nitrogen adsorption / desorption isotherms (BET). In the present study, the mentioned adsorbent was used moderately for removal of cadmium ions from aqueous solutions and was compared with two other adsorbents of cadmium, activated carbon and silica aerogel. The experiments of Cd adsorption by adsorbents were performed at different initial ion concentration, pH of the solution, adsorption temperature, adsorbent dosage and contact time. Moreover, the optimum pH for the adsorption was found to be 6.0 with corresponding adsorbent dosage level of 0.1 g at 60 ̊C temperature. Subsequently, the equilibrium was achieved for Cd with 120 minutes of contact time. Consequently, the results show that using this composite adsorbent could remove more than 60% of Cd under optimum experimental conditions. Langmuir and Freundlich isotherm model was applied to analyze the data, which the adsorption equilibrium data were correlated well with the Freundlich isotherm model and equilibrium adsorption capacity (qe) was found to be 0.384mg/g in the 3mg/L solution of cadmium.
One Approach to intellectual image analysis

This study investigated the method of semantic image analysis by using a set of neuron-like detectors of foreground objects. This method is intended to find different types of foreground objects and to determine properties of these objects. As a result of semantic analysis the semantic descriptor of the image is created. The descriptor is a set of foreground objects of the image and a set of properties for each object. The distance between images is defined as distance between their semantic descriptors. Using the concept of distance between images, “semantically similarity” between images or videos is defined.
IMPLICATIONS FOR ASSESSMENT AND TREATMENT

The past decade has witnessed a growing awareness of the prevalence and consequences of childhood sexual abuse. This paper presents findings from numerous studies which indicate that adult survivors of incest suffer from devastating personal and interpersonal difficulties. Recent studies on incest claim that some 20 percent of females and over 16 percent of males, suffered an incestuous episode at some point in their childhood. Survivors often reveal in therapy a variety of cognitive, emotional, physical, and interpersonal difficulties. These problems and their interactions form the incest survivor syndrome. Because of the powerful consequences of incest on the victim, a diagnosis of post-traumatic stress disorder needs to be given to the survivor in addition to the diagnosis of the presenting complaint. A dual diagnosis will assist the clinician, the patient, and his/her family in normalizing the presenting problems and in depathologizing the survivor. The multiplicity of survivors' problems calls for an integrative treatment approach which is technically eclectic, including among other strategies and techniques, cognitive/behavioral, psychodynamic, and family systems work. Additionally, treatment of married survivors, or those in committed relationships, should include spouses or partners. (Contains 49 references.)

Beastie Meets Raccoon: MINIX 3 as a BSD

MINIX 3 has imported a significant amount of userland BSD code. The trend began several years ago, but the pace has quickened markedly. We have already imported NetBSD’s buildsystem, NetBSD’s C library, the pkgsrc package management infrastructure, and various userland utilities from NetBSD and FreeBSD. We are currently in the process of porting a full NetBSD userland as well as puffs for increased filesystem support. Though not technically BSD code, we have adopted clang/LLVM as our default toolchain, and we are working to adopt elftoolchain as a binutils replacement. When MINIX 3 was originally conceived, the goal was to create a robust multiserver operating system that maintains POSIX compatibility. We leveraged our multiserver architecture in which most OS code runs in separate usermode processes to provide new functionality, such as driver isolation and restartability. Now, we would like to push farther than just POSIX compatibility and provide a system that looks much like a BSD from a user’s perspective. This paper serves as a progress report on our ongoing work turning MINIX 3 into a BSD. We have a long way to go before MINIX implements all BSD functionality, but we have a good start. We will continue to pull in BSD code, and we have identified future opportunities to pull in driver code and kernel components from BSD. This will serve to enable our vision of the best of both worlds: isolation and restartability features unique to Minix combined with the well-maintained, real-world-hardened system code for drivers, filesystems, userland, and other OS code, of a modern BSD OS.
