Long-term monthly average temperature forecasting in some climate types of Iran, using the models SARIMA, SVR, and SVR-FA

Temporal changes of the global surface temperature have been used as a prominent indicator of global climate change; therefore, making dependable forecasts underlies the foundation of sound environmental policies. In this research, the accuracy of the Seasonal Autoregressive Integrated Moving Average (SARIMA) Stochastic model has been compared with the Support Vector Regression (SVR) and its merge

Pharmacological inactivation of CDK2 inhibits MYC/BCL-XL-driven leukemia in vivo through induction of cellular senescence

Deregulated expression of the MYC oncogene is a frequent event during tumorigenesis and generally correlates with aggressive disease and poor prognosis. While MYC is a potent inducer of apoptosis, it often suppresses cellular senescence, which together with apoptosis is an important barrier against tumor development. For this latter function, MYC is dependent on cyclin-dependent kinase 2 (CDK2). H

Imaging in gynecological disease (20) : clinical and ultrasound characteristics of adnexal torsion

Objectives: To describe the clinical and ultrasound characteristics of adnexal torsion. Methods: This was a retrospective study. From the operative records of the eight participating gynecological ultrasound centers, we identified patients with a surgically confirmed diagnosis of adnexal torsion, defined as surgical evidence of ovarian pedicle, paraovarian cyst and/or Fallopian tube twisted on its

Resilience in Virtual Teams : Developing the Capacity to Bounce Back

Resilience, or the capacity to bounce back from adversity strengthened and more resourceful, can be considered an important quality of virtual teams in the contemporary working world. A team is the basic organizational unit many modern firms are composed of—and, the virtual ones are those conducting teamwork over distance using a combination of telecommunications and information technologies to ac

White matter hyperintensity burden in acute stroke patients differs by ischemic stroke subtype

ObjectiveTo examine etiologic stroke subtypes and vascular risk factor profiles and their association with white matter hyperintensity (WMH) burden in patients hospitalized for acute ischemic stroke (AIS).MethodsFor the MRI Genetics Interface Exploration (MRI-GENIE) study, we systematically assembled brain imaging and phenotypic data for 3,301 patients with AIS. All cases underwent standardized we

Letting rationalizations out of the box

We are very happy that someone has finally tried to make sense of rationalization. But we are worried about the representational structure assumed by Cushman, particularly the "boxology" belief-desire model depicting the rational planner, and it seems to us he fails to accommodate many of the interpersonal aspects of representational exchange.

The effects of CGRP in vascular tissue - Classical vasodilation, shadowed effects and systemic dilemmas

Vascular tissue consists of endothelial cells, vasoactive smooth muscle cells and perivascular nerves. The perivascular sensory neuropeptide CGRP has demonstrated potent vasodilatory effects in any arterial vasculature examined so far, and a local protective CGRP-circuit of sensory nerve terminal CGRP release and smooth muscle cell CGRP action is evident. The significant vasodilatory effect has sh

Concept of a transductive link

This theoretical paper defines and explores the concepts of transductive links and transductive chains, as part of the theoretical framework of social semiotics. Social semiotics stems from the multimodal framework, which provides a theoretical perspective, constructs, and a language to describe a shift of semiotic material within or between semiotic systems, such as rewriting a text or moving fro

Energy 4 all? Investigating gendered energy justice implications of community-based micro-hydropower cooperatives in Ethiopia

More than 70% of the population in Ethiopia lack access to electricity and thus rely on conventional sources of energy such as biomass that is associated with negative consequences on health and the environment. Decentralized community-based micro-hydropower plants (MHPs) are being utilized as effective means to transition to modern low-carbon energy systems providing access to electricity to comm

Climate change : challenges and opportunities to scale up surgical, obstetric, and anaesthesia care globally

Climate change affects human health in a myriad of ways, requiring reassessment of the nature of scaling up care delivery and the effect that care delivery has on the environment. 5 billion people do not have access to safe and timely surgical care, and the quantity and severity of conditions that require surgical, obstetric, and anaesthesia care will increase substantially as a result of climate

The future of capsule endoscopy in clinical practice : From diagnostic to therapeutic experimental prototype capsules

Capsule endoscopy (CE) is indicated as a first-line clinical examination for the detection of small-bowel pathology, and there is an ever-growing drive for it to become a method for the screening of the entire gastrointestinal tract (GI). Although CE's main function is diagnosis, the research for therapeutic capabilities has intensified to make therapeutic capsule endoscopy (TCE) a target within r

Importance of gestational hypoglycaemia for foetal malformations and skeletal development in rats

The aim was to investigate embryo-foetal effects of continuous maternal insulin-induced hypoglycaemia extending throughout gestation or until gestation day (GD)17 (typical last day of dosing during pre-clinical evaluation) providing comparator data for safety assessment of longer-acting insulin analogues in non-diabetic rats. Pregnant rats received human insulin (HI)-infusion during gestation unti

An energy-relaxation-based framework for the modelling of magnetic shape memory alloys—Simulation of key response features under homogeneous loading conditions

In this contribution we present a constitutive modelling framework for magnetic shape memory alloys (MSMA) that builds on a global variational principle. The approach relies on concepts of energy relaxation and generalised notions of convexity to compute effective energy hulls to the non-convex energy landscape associated with the underlying multi-phase solid, from which the prediction of microstr

Home oxygen therapy for adults with chronic lung disease an official american thoracic society clinical practice guideline

Background: Evidence-based guidelines are needed for effective delivery of home oxygen therapy to appropriate patients with chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). Methods: The multidisciplinary panel created six research questions using a modified Delphi approach. A systematic review of the literature was completed, and the Grading of Recommendations Asse

Data-driven control of infinite dimensional systems : Application to a continuous crystallizer

Controlling infinite dimensional models remains a challenging task for many practitioners since they are not suitable for traditional control design techniques or will result in a high-order controller too complex for implementation. Therefore, the model or the controller need to be reduced to an acceptable dimension, which is time-consuming, requires some expertise and may introduce numerical err

A certification scheme for operation of buildings with well-planned and ambitious environmental improvements

The development of environmental certification schemes has increased rapidly during the last twenty years and are often used as benchmarks during design of new buildings or reconstruction. However, for management of our existing buildings the members of Sweden Green Building Council request for clear guidelines and a certification scheme. Therefore, a new certification scheme called Miljöbyggnad i
