Parallel point symmetry based clustering for gene microarray data

Point symmetry-based clustering is an important unsupervised learning tool for recognizing symmetrical convex or non-convex shaped clusters, even in the microarray datasets. To enable fast clustering of this large data, in this article, a distributed space and time-efficient scalable parallel approach for point symmetry-based K-means algorithm has been proposed. A natural basis for analyzing gene

Principles for the design of a policy framework to address product life cycle impacts

Introduction: Product-oriented environmental law is an expanding, poly-thematic subsection of environmental law. First, an increasing number of policy instruments are being used at the international, European and national levels to regulate products, including mandatory performance standards, consumer subsidies, public procurement practices, product bans, taxes and charges and various kinds of man

Public opinion, party politics, and the welfare state

This chapter examines the long-run relationship between public opinion, party politics, and the welfare state. It argues that when large parties receive a clear signal concerning the median voter’s position on the welfare state, vote-seeking motivations dominate and the large parties in the party system converge on the position of the median voter. When the position of the median voter is more dif

Surface Characterization of AD730TM Part Produced in High Speed Turning with CBN tool

AD730TM is a novel superalloy developed for the hot section part in aero engine and gas turbine machinery with enhanced performance. The material is characterized by its excellent high temperature properties for being an alloy possible to manufacture by cast and wrought process compared to other superalloys in the same class such as Inconel718. The material with higher temperature capability means

Plastic Deformation and Residual Stress in High Speed Turning of AD730™ Nickel-based Superalloy with PCBN and WC Tools

A higher gas turbine efficiency can be achieved by increasing the operating temperature in hot sections. AD730™ is a recently-developed wrought/cast nickel-based superalloy which can maintain excellent mechanical properties above 700. However, machining of AD730™ could be a difficult task like other nickel-based superalloys. Therefore, studies are needed with respect to the machinability of this n

Preconditioned Smoothers for the Full Approximation Scheme for the RANS Equations

We consider multigrid methods for finite volume discretizations of the Reynolds averaged Navier–Stokes equations for both steady and unsteady flows. We analyze the effect of different smoothers based on pseudo time iterations, such as explicit and additive Runge–Kutta (AERK) methods. Furthermore, by deriving them from Rosenbrock smoothers, we identify some existing schemes as a class of additive W

Bioinspired Structural Hierarchy within Macroscopic Volumes of Synthetic Composites

A key challenge in developing bioinspired composites is the fabrication of well-defined 3D hierarchical structures ranging from nano to the macroscale. Herein, the development of a synthetic polymer-apatite composite realized by integrating bottom-up self-assembly and additive manufacturing (AM) is described. The resulting composite exhibits a bioinspired hierarchical structure over its 3D macrosc

Doctoral students’ well-being : a literature review

Purpose: Doctoral student well-being is an important matter that shapes the well-being of academics throughout their careers. Given that well-being has been found to be closely related to employee productivity and efficiency, strategies associated with maintaining well-being during PhD studies might be crucial for higher education, its outcomes and—just as importantly—for a balanced life of PhD st

Spatiotemporal pattern of Wnt-canonical pathway in dorsal telencephalic organoids.

In the last decade, organoid technology has filled the gap generated by the poor accessibility and unique features of the human brain. Organoids present several advantages in comparison with two-dimensional culturing, since they recapitulate cytoarchitecture in space and functionality of the tissue. Therefore, they mimic the unique features of human brain better than animal models. Although signif

The Impact of Living with Parkinson's Disease : Balancing within a Web of Needs and Demands

This study explores the impact of living with Parkinson's disease (PD). Nineteen persons (11 women) aged 55-84 diagnosed with PD 3-27 years ago participated. Data were collected through semistructured interviews, which were recorded, transcribed verbatim, and analysed by qualitative content analysis. Four categories represented the impact of living with PD: "Changed prerequisites for managing day-

A Protein-Based Encapsulation System with Calcium-Controlled Cargo Loading and Detachment

Protein-based encapsulation systems have a wide spectrum of applications in targeted delivery of cargo molecules and for chemical transformations in confined spaces. By engineering affinity between cargo and container proteins it has been possible to enable the efficient and specific encapsulation of target molecules. Missing in current approaches is the ability to turn off the interaction after e

Age- and Gender-Specific Normative Values for the Self-Reported Foot and Ankle Score (SEFAS)

BACKGROUND: The Self-Reported Foot and Ankle Score (SEFAS) is a foot- and ankle-specific patient-reported outcome measurement (PROM) score that has been validated with good results for a variety of foot and ankle disorders. SEFAS is sensitive detecting improvement or deterioration after surgery. However, normative values, required to put a specific patient's summary score into perspective, are lac

Serum DHEA and Its Sulfate Are Associated With Incident Fall Risk in Older Men : The MrOS Sweden Study

The adrenal-derived hormones dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are the most abundant circulating hormones and their levels decline substantially with age. Many of the actions of DHEAS are considered to be mediated through metabolism into androgens and estrogens in peripheral target tissues. The predictive value of serum DHEA and DHEAS for the likelihood of falling is unknown. T

Orbital modulation of ENSO seasonal phase locking

Modern El Niño-Southern Oscillation (ENSO) events are characterized by their phase locking of variability to the seasonal cycle and tend to peak at the end of calendar year. Here, we show that in an idealized NCAR-CCSM3 simulation of the climate of the last 300,000 years, ENSO seasonal phase locking is shifted periodically following the precessional forcing: ENSO tends to peak in boreal winter whe

Complications, long-term outcome and quality of life following Surgisis® and muscle-covered implants in immediate breast reconstruction : a case-control study with a 6-year follow-up

Background: Matrices are now commonly used in breast reconstruction, but the scientific evidence is still scares. The main aim was to compare complications and the need for corrections in immediate breast reconstruction with the porcine-derived Surgisis® with the traditional muscle-covered technique. The secondary aim was to compare long-term quality of life and satisfaction. Methods: All consecut

Energy efficiency regulations, market and behavioural failures and standardization

Introduction: A large number of policy instruments have been developed to induce energy efficiency and mitigate climate change. Traditional policy evaluations have assessed the performance of individual policy instruments, applying criteria such as target effectiveness, cost-effectiveness, legitimacy and distributional effects. More recently there has been a shift of interest in how policy instrum

Hypermethylation of endoplasmic reticulum disulfide oxidase 1α leads to trophoblast cell apoptosis through endoplasmic reticulum stress in preeclampsia

Abnormal trophoblast cell apoptosis is implicated in the pathogenesis of pregnancy-related disorders including preeclampsia (PE), and endoplasmic reticulum (ER) stress has been considered as a novel pathway in the regulation of cell apoptosis. In this study, we observed that both apoptosis and ER stress are triggered in trophoblast cells under hypoxia as well as in the placenta of PE rats. Quantit
