Proximal Aortic Dissection with Rupture into the Main Pulmonary Artery—A Case Report

Aim: To present a rare occurrence of aortopulmonary fistula due to rupture of proximal aortic dissection in a 48-year-old woman. Introduction: Aortic dissection is defined as disruption of the medial layer provoked by intramural bleeding, resulting in separation of aortic wall layers and subsequent formation of a true lumen and a false lumen with or without communication. Case Report: A 48-year-old female presented with vague anterior chest discomfort, high blood pressure, systolic-diastolic murmur in the left sternal border with ECG changes of myocardial ischemia. Echocardiography revealed a dilated aortic root with intimal flaps, a leak into the pulmonary artery and regional hypokinesis with contractile dysfunction suggesting a proximal aortic dissection with rupture into the main pulmonary artery. Discussion: The etiology of aortic dissection was mostly hypertension in 80% of cases and aortopathies such as connective tissue disorders, inflammatory and idiopathic. Aortic wall stress is a major trigger of intimal tear and two-dimensional transthoracic echocardiography is an excellent, initial diagnostic gold standard to detect the dissecting flaps, especially in proximal aortic dissection. Conclusion: Blood pressure control is the mainstay of treatment and urgent surgery is indicated in proximal aortic dissection since there is higher chance of rupture with an increase in mortality.
LGS-IV Capsules : Time to Reposition ?

The PillCam Colon 2 capsule (Given Imaging Covidien GI Solutions) has been developed for the examination of the colonic mucosa, with a similar technology as that of endoscopic capsules used for the examination of the small bowel. The second version of this colonic capsule endoscopy (CCE) has been improved with various technical advances: a wider angle of view of 172 ° instead of 156 °, which allows a better examination of the colonic mucosa, and a variable frame rate frequency that can vary between 4 and 35 frames per second, providing a better visualization of colonic segment where the capsule progresses rapidly, in particular in the transverse colon. In parallel with these technical advances in the capsule, the reading software provided by Given Imaging (Rapid Access 8) has also been improved and includes a function to facilitate the estimation of polyp size as well as the possibility of FICE-type electronic coloration (Fujifilm Inc. Omiya, Japan), which highlights polyp structure and changes in vasculature, as in conventional colonoscopy. Several clinical studies have been performed since 2009, collecting data mainly on the ability of the CCE to detect colonic polyps. The results of these studies indicate possible clinical indications of CCE, all of them remaining currently under evaluation.
A Review on Software-Defined Networking Distributed Controllers

A computer network is a critical issue in our day to day activity; however, today it works under various problems. Since in the current network architecture the control plane and data plane are vertically bundled on the same device. To solve this problem programmable Software-Defined Network is released. OpenFlow is a protocol that vertically separates control plane and data plane of the network devices. In SDN the controllers are the brains of the network that controls the network devices. Today’s network required successful integration of distributed controllers to make the network more consistent. SDN distributed controller is a controller that we can add or remove the controllers according to the number of devices change. Distributed controller architecture has investigated and compared the 6 recent distributed controllers by using 26 criteria. Orion is the first best controller and ONOS is the second best controller.
New developments in transport of intensity equation for phase retrieval and computational imaging

The commonly known transport of intensity equation (TIE) was proposed by Teague as a method for the deterministic optical phase-retrieval problem. The aim is to deduce optical phase from only intensity measurements using non-interferometric techniques. Compared to many other phase retrieval algorithms, TIE is non-iterative, purely computational and no complicated auxiliary device needs to be introduced. In this paper, we introduce some recent developments in TIE phase retrieval and microscopy: including its fast numerical solution, treatment of boundary problem and the low-frequency artifacts, and two configurations for dynamic phase imaging. We also reexamine TIE in terms of phase-space optics, demonstrating the effect of partially coherent illumination on phase reconstruction, and connecting it to light field imaging at the geometry optics limit.
PRMT 4 is involved in insulin secretion via the methylation of histone H 3 in pancreatic b cells

The relationship between protein arginine methyltransferases (PRMTs) and insulin synthesis in b cells is not yet well understood. In the present study, we showed that PRMT4 expression was increased in INS-1 and HIT-T15 pancreatic b cells under high-glucose conditions. In addition, asymmetric dimethylation of Arg17 in histone H3 was significantly increased in both cell lines in the presence of glucose. The inhibition or knockdown of PRMT4 suppressed glucose-induced insulin gene expression in INS-1 cells by 81.6 and 79% respectively. Additionally, the overexpression of mutant PRMT4 also significantly repressed insulin gene expression. Consistently, insulin secretion induced in response to high levels of glucose was decreased by both PRMT4 inhibition and knockdown. Moreover, the inhibition of PRMT4 blocked high-glucose-induced insulin gene expression and insulin secretion in primary pancreatic islets. These results indicate that PRMT4 might be a key regulator of high-glucoseinduced insulin secretion from pancreatic b cells via H3R17 methylation. Key Words
Spatially resolved electronic structure of twisted graphene

We have used scanning tunneling microscopy and spectroscopy to resolve the spatial variation of the density of states of twisted graphene layers on top of a highly oriented pyrolytic graphite substrate. Owing to the twist a moire pattern develops with a periodicity that is substantially larger than the periodicity of a single layer graphene. The twisted graphene layer has electronic properties that are distinctly different from that of a single layer graphene due to the nonzero interlayer coupling. For small twist angles (∼1-3.5) the integrated differential conductivity spectrum exhibits two well-defined Van Hove singularities. Spatial maps of the differential conductivity that are recorded at energies near the Fermi level exhibit a honeycomb structure that is comprised of two inequivalent hexagonal sublattices. For energies |E-EF|>0.3eV the hexagonal structure in the differential conductivity maps vanishes. We have performed tight-binding calculations of the twisted graphene system using the propagation method, in which a third graphene layer is added to mimic the substrate. This third layer lowers the symmetry and explains the development of the two hexagonal sublattices in the moire pattern. Our experimental results are in excellent agreement with the tight-binding calculations.
Wavelet and shearlet-based image representations for visual servoing

A visual servoing scheme consists of a closed-loop control approach that uses visual information feedback to control the motion of a robotic system. Probably the most popular visual servoing method is image-based visual servoing (IBVS). This kind of method uses geometric visual features extracted from the image to design the control law. However, extracting, matching, and tracking geometric visual features over time significantly limits the versatility of visual servoing controllers in various industrial and medical applications, in particular for “low-structured” medical images, e.g. ultrasounds and optical coherence tomography modalities. To overcome the limits of conventional IBVS, one can consider novel visual servoing paradigms known as “direct” or “featureless” approaches. This paper deals with the development of a new generation of direct visual servoing methods in which the signal control inputs are the coefficients of a multiscale image representation. In particular, we consider the use of multiscale image representations that are based on discrete wavelet and shearlet transforms. Up to now, one of the main obstacles in the investigation of multiscale image representations for visual servoing schemes was the issue of obtaining an analytical formulation of the interaction matrix that links the variation of wavelet and shearlet coefficients to the spatial velocity of the camera and the robot. In this paper, we derive four direct visual servoing controllers: two that are based on subsampled respectively non-subsampled wavelet coefficients and two that are based on the coefficients of subsampled respectively non-subsampled discrete shearlet transforms. All proposed controllers were tested in both simulation and experimental scenarios (using a six-degree-of-freedom Cartesian robot in an eye-in-hand configuration). The objective of this paper is to provide an analysis of the respective strengths and weaknesses of wavelet- and shearlet-based visual servoing controllers.
Man-induced salinity and temperature increases in western Mediterranean deep water. (Reannouncement with new availability information)

The historical data base is used to study property changes in both the Western Mediterranean Deep Water (WMDW) and the Levantine Intermediate Water (LIW). Changes in WMDW properties during the past century have been described previously, although on a more limited data base. We are not aware of any previous study of changes in LIW properties. In the extensive data base we used, increases appear in both WMDW temperature and salinity, from 1909 to the present, which substantiate previously reported observations. In addition, we find that the density of WMDW seems to have increased as well, which disagrees with previous suggestions that it has remained constant. We observe that the WMDW temperature increase displays a distinct acceleration starting about 1955 and that a similar, although less conspicuous, acceleration occurs in the WMDW salinity increase. From our study of historical data on LIW properties, the LIW salinity also appears to have increased since 1909. We argue that the warming trend in WMDW may well be a response to the salinity increase, which seems to be imported from the eastern Mediterranean by LIW, and as such our observations endorse a recently published hypothesis. The increase in LIW salinity, in turn, is attributedmore » to changes in the eastern Mediterranean freshwater budget, resulting from damming of major rivers that drain either directly or indirectly into the eastern Mediterranean. « less
A Novel Framework for Sustainable Traffic Safety Programs Using the Public as Sensors of Hazardous Road Information

Traditionally, traffic safety improvement programs (TSIPs) have been based on the number of crashes at a specific location or their severity. However, the crash datasets used for such programs are obtained from the police and include two limitations: not all crashes are collected by the police (most minor and near-miss crashes are not reported), and the traditional process uses crash data recorded for the past two or three years (meaning most data inevitably include a time lag). To overcome these limitations, this study proposes a new approach for a TSIP based on citizen participation through an online survey that is broadcasted through social media. The method uses the public as sensors of hazardous road information, which means that information can be collected on individual experiences of minor crashes and latent risk factors, such as near misses and traffic conflicts. To demonstrate this approach, a case study was carried out in a small district in the city of Goyang, Korea, which has one of the highest usage rates of social media technologies. The proposed method and a traditional method were both assessed.
A Prospective Study of Thoracolumbar Pott’s Spine Treated at a Tertiary Care Centre by Posterior Decompression Alone

Original Research Article In order to extract current trends in diagnosis and medical or surgical treatment of spinal TB we performed a review with patients admitted to our hospital between 2016 and 2017. Although the development of more accurate imaging modalities such as magnetic resonance imaging and advanced surgical techniques have made the early diagnosis and management of spinal TB much easier, these are still very challenging topics. In this review we aim to discuss the diagnosis and management of spinal TB based on studies with acceptable design, clearly explained results and justifiable conclusions.

Strategic Abuse and Accuser Credibility

We study the interplay between the incentive for a potential abuser (principal) to commit crime and incentives for potential victims (agents) to report crime. When the punishment faced by a convicted principal is large relative to the benefit of crime, the principal’s decisions to abuse agents are strategic substitutes and agents’ decisions to report crime are strategic complements. This induces a negative correlation in agents’ private information and a coordination motive across agents. This tension renders agents’ reports arbitrarily uninformative and leads to a high probability of crime. Remedies include reducing the punishment faced by a convicted principal, and treating crimes against each individual separately.
Monoterpene pollution episodes in a forest environment: indication of anthropogenic origin and association with aerosol particles

We used a monoterpene volume mixing ratio dataset measured from 12 June 2006 to 24 September 2007 and from 1 June 2008 to 3 March 2009 at the SMEAR II station to quantify the magnitude of anthropogenic monoterpene emissions aside from biogenic origins, to examine the anthropogenic sources, and to look at other associated pollutants. We discuss the relations between increased monoterpene mixing ratios and particle concentrations. We also characterize chemical properties of aerosol particles during two monoterpene pollution episodes in case studies. Out of 580 days analyzed, anthropogenic monoterpene pollution episodes were found on 341 (58.8%) days. The average monoterpene mixing ratio increased from 0.19 to 0.26 ppbv due to the presence of anthropogenic monoterpenes, which is equal to an increase of 36.8%. The observed anthropogenic monoterpenes were mostly from the Korkeakoski sawmill. Other gas pollutants might occasionally be emitted during the episodes, but did not show clear association with anthropogenic monoterpenes. Aerosol particle concentrations substantially increased during episodes, and monoterpene mixing ratios showed strong connections with Aitken mode particles both in number and volume concentrations. Particles associated with monoterpene episodes reached a CCN (cloud concentration nucleus) size. The chemical characterizations of aerosol particles in case studies show that the increase in aerosol particle mass was mainly from secondary organic aerosol.
Series of Highly Stable Isoreticular Lanthanide Metal–Organic Frameworks with Expanding Pore Size and Tunable Luminescent Properties

A series of highly porous isoreticular lanthanide-based metal–organic frameworks (LnMOFs) denoted as SUMOF-7I to SUMOF-7IV (SU = Stockholm University; Ln = La, Ce, Pr, Nd, Sm, Eu, and Gd) have been synthesized using tritopic carboxylates as the organic linkers. The SUMOF-7 materials display one-dimensional pseudohexagonal channels with the pore diameter gradually enlarged from 8.4 to 23.9 A, as a result of increasing sizes of the organic linkers. The structures have been solved by single crystal X-ray diffraction or rotation electron diffraction (RED) combined with powder X-ray diffraction (PXRD). The SUMOF-7 materials exhibit robust architectures with permanent porosity. More importantly, they exhibit exceptionally high thermal and chemical stability. We show that, by inclusion of organic dye molecules, the luminescence properties of the MOFs can be elaborated and modulated, leading to promising applications in sensing and optics.
Environmental Stress Cracking (ESC) and Slow Crack Growth (SCG) of PE-HD induced by external fluids

High-density polyethylene (PE-HD) is widely used as a packaging material. Typical applications are pipes and containers for storage and transport of dangerous goods. For these applications, the understanding of the craze-crack damage mechanisms slow crack growth (SCG) and environmental stress cracking (ESC) is of importance. Since these mechanisms are considered to be the major causes of failure, their understanding is essential for inspection and release of those materials. A well-established test method for the assessment of these damage mechanisms is the full-notch creep test (FNCT). It is used in this study for a detailed investigation of crack propagation phenomena in PE-HD container materials under the influence of different fluids such as air, water and aqueous detergent solutions (Arkopal N 100) as well as biodiesel and diesel. Based on the results of the FNCT, a classification scheme of different fluids is proposed, which allows for an assignment of the respective damage mechanisms. Hereby, it is differentiated between (i) inert, (ii) purely surface-active and (iii) additionally sorptive, bulk-active fluids with respect to SCG. If the test fluid changes the intrinsic properties (at the surface or in the bulk), the damage mechanism is addressed to ESC behavior. In FNCT investigations, stress, temperature and specimen geometry were varied systematically. In addition to the time to failure as common measure for the resistance of a PE-HD type against crack propagation, specimen elongation was considered in detail. Several imaging techniques were applied for fracture surface analysis of specimens tested in FNCT to gain novel information on SCG and ESC behavior. From height profiles obtained by laser scanning microscopy (LSM) and information on surface structures from scanning electron microscopy (SEM), indicators for the differentiation of the crack propagation mechanisms could be derived. Based on the LSM data, an algorithm for the distinction between ductile shear deformation and brittle crack growth as dominating failure mechanism was developed. Imaging techniques were also used for determination of crack propagation rates, which were related to time-resolved FNCT elongation data. From the time-resolved determination of crack lengths of partly damaged FNCT specimens, an increasing length of craze zone with a progressively propagating crack was revealed for the first time. This relation of crack and craze zones was specified by fracture mechanical considerations.
CuSP: A Customizable Streaming Edge Partitioner for Distributed Graph Analytics

Graph analytics systems must analyze graphs with billions of vertices and edges which require several terabytes of storage. Distributed-memory clusters are often used for analyzing such large graphs since the main memory of a single machine is usually restricted to a few hundreds of gigabytes. This requires partitioning the graph among the machines in the cluster. Existing graph analytics systems usually come with a built-in partitioner that incorporates a particular partitioning policy, but the best partitioning policy is dependent on the algorithm, input graph, and platform. Therefore, built-in partitioners are not sufficiently flexible. Stand-alone graph partitioners are available, but they too implement only a small number of partitioning policies. This paper presents CuSP, a fast streaming edge partitioning framework which permits users to specify the desired partitioning policy at a high level of abstraction and generates high-quality graph partitions fast. For example, it can partition wdc12, the largest publicly available web-crawl graph, with 4 billion vertices and 129 billion edges, in under 2 minutes for clusters with 128 machines. Our experiments show that it can produce quality partitions 6× faster on average than the state-of-the-art stand-alone partitioner in the literature while supporting a wider range of partitioning policies.
Expanding the Non-invasive Coronary Physiology Assessment with Transthoracic Doppler Echocardiography

Coronary angiography has been considered the gold standard for defining coronary anatomy for more than four decades. Nevertheless, this technique has intrinsic limitations because it only delineates coronary luminology , and it has been clearly shown that there is marked disparity between the severity of lesions and their physiological effects in ischemic heart disease (CAD). Both coronary angiography and intravascular ultrasound can only give anatomic information and cannot provide sufficient functional information which is crucial for clinical decision making, especially in intermediate stenoses. It conveys that physiologic variables, such as coronary flow velocity reserve (CFVR), are more widely accepted and used as an additional approach to complement coronary luminology and assess the functional status of a patient as much as or more than anatomic variables. Methods of measurement of coronary flow and CFVR including intracoronary Doppler flow wire, nuclear technique such as PET and echo technique such as transesophageal echocardiography (TEE) have been explored in the past years. In the clinical setting CFVR is usually measured in the cardiac catheterization laboratory by means of small Doppler guide-wires positioned in the coronary lumen. This method is certainly very precise, but not repeatable for its obvious invasivity and high cost. PET is a promising technique of the non-invasive measurement of CFVR, but since it is extremely expensive, it is scarcely available. Recently, accurate non-invasive assessment of CFVR by means of the transthoracic second-harmonic Doppler echocardiography (TTDE), with eventual use of intravenous
Improving Rumen Fermentability and Fiber Fraction Digestion of Fermented Rice Straw with A Cattle Feed Supplement and A Concentrate

Original Research Article This study aimed to obtain the best ration with the use of fermented rice straw (RF) as a basal feed for cattle farms. The RF was made by fermenting rice straw using Rhizopus oligosporus. The concentrate consisted of many locally available feed ingredients. The supplement was composed of several feeds as a multinutrient to supplement any deficiencies in the ration. There were 4 treatment rations: RF = 100% RF (control), RFS = RF + 10% supplement, RFSC = RFS + 10% concentrate, and RFSC2 = RFS + 20% concentrate. The rations were tested by in vitro digestion using bovine rumen fluid and 48 hours of incubation at 39 °C under anaerobic conditions. The results showed that the addition of the supplement significantly increased the digestibility of the dry matter, organic matter, crude protein, and hemicellulose, while the addition of the concentrate significantly increased the concentration of VFAs and the digestibility of NDF and cellulose. The best composition was an 80:10:10 (% DM) mixture of RF, supplement and concentrate.
Logistic Regression: An Inferential Method for Identifying the Best Predictors

When dealing with a logistic regression model, there is a simple method for estimating the strength of the association between the jth covariate and the dependent variable when all covariates are entered into the model. There is the issue of determining whether the jth independent variable has a stronger or weaker association than the kth independent variable. This note describes a method for dealing with this issue that was found to perform reasonably well in simulations.
