Introducing reinforcement learning to the energy system design process

Design optimization of distributed energy systems has become an interest of a wider group of researchers due the capability of these systems to integrate non-dispatchable renewable energy technologies such as solar PV and wind. White box models, using linear and mixed integer linear programing techniques, are often used in their design. However, the increased complexity of energy flow (especially

Exploration of jet substructure using iterative declustering in pp and Pb–Pb collisions at LHC energies

The ALICE collaboration at the CERN LHC reports novel measurements of jet substructure in pp collisions at s=7 TeV and central Pb–Pb collisions at sNN=2.76 TeV. Jet substructure of track-based jets is explored via iterative declustering and grooming techniques. We present the measurement of the momentum sharing of two-prong substructure exposed via grooming, the zg, and its dependence on the openi

Exploring publication productivity in the Philippines: A 10-year gendered analysis of six academic disciplines

This article presents a gendered analysis exploring publication productivity in the Philippines using bibliometric data from the Web of Science. It investigates the temporal pattern of journal article publications for six disciplines, its gendered distribution, differences between disciplines, patterns of authorship and collaboration, and how much women authors contribute and participate in resear

Expanding the EU Internal Market without Enlarging the Union: Constitutional Limitations

One of the most significant roles of the EU in the world is that of being a norms exporter. The EU has concluded numerous agreements with countries in its neighbourhood with the aim of encouraging third countries to adopt EU acquis in exchange for access to the internal market. The most ambitious of these agreements are the three multilateral agreements establishing the European Economic Area, the

D-wave effects in diffractive electroproduction of heavy quarkonia from the photon-like V→ QQ¯ transition

We analyse the validity of a commonly used identification between structures of the virtual photon γ∗→ QQ¯ and vector meson V→ QQ¯ transitions. In the existing studies of S-wave vector-meson photoproduction in the literature, such an identification is typically performed in the light-front (LF) frame while the radial component of the meson wave function is rather postulated than computed from the

Prompt hadroproduction of ηc(1S, 2S) in the kT-factorization approach

In this work, we present a thorough analysis of ηc(1S, 2S) quarkonia hadroproduction in k⊥-factorisation in the framework of the light-front potential approach for the quarkonium wave function. The off-shell matrix elements for the g*g*ηc(1S, 2S) vertices are derived. We discuss the importance of taking into account the gluon virtualities. We present the transverse momentum distributions of ηc for

The value of travel guidebooks in the digital age

Travel guidebooks are both travel information channels and objects of consumption. In contemporary tourism, Information and Communication Technologies (ICT) make information abundant and mostly free of charge. Therefore, as tourists still buy them, there must be something that makes guidebooks a valuable object. This research aims at understanding the value of travel guidebooks in the digital age.

Beta secretase 1-dependent amyloid precursor protein processing promotes excessive vascular sprouting through NOTCH3 signalling

Amyloid beta peptides (Aβ) proteins play a key role in vascular pathology in Alzheimer’s Disease (AD) including impairment of the blood–brain barrier and aberrant angiogenesis. Although previous work has demonstrated a pro-angiogenic role of Aβ, the exact mechanisms by which amyloid precursor protein (APP) processing and endothelial angiogenic signalling cascades interact in AD remain a largely un

Exploring the visual world of fossilized and modern fungus gnat eyes (Diptera : Keroplatidae) with X-ray microtomography

Animal eyes typically possess specialized regions for guiding different behavioural tasks within their specific visual habitat. These specializations, and evolutionary changes to them, can be crucial for understanding an animal's ecology. Here, we explore how the visual systems of some of the smallest flying insects, fungus gnats, have adapted to different types of forest habitat over time (approx

Evaluation of 18F-FDG uptake in lung parenchyma compensating for tissue fraction : Comparison between non-enhanced low dose CT and intravenous contrast-enhanced diagnostic CT

AIM: To determine how the presence of intravenous (IV) contrast-enhanced CT influences SUV measurements corrected for both attenuation and tissue fraction. MATERIAL AND METHODS: Eighteen patients with different malignancies, free from lung disorders, lung cancer or metastasis, were prospectively recruited when referred for staging with combined 18F-FDG-PET/CT examination. A non-enhanced low-dose C

Denoising of Scintillation Camera Images Using a Deep Convolutional Neural Network : A Monte Carlo Simulation Approach

Scintillation camera images contain a large amount of Poisson noise. We have investigated whether noise can be removed in whole-body bone scans using convolutional neural networks (CNNs) trained with sets of noisy and noiseless images obtained by Monte Carlo simulation. Methods: Three CNNs were generated using 3 different sets of training images: simulated bone scan images, images of a cylindric p

Women with a predisposition for diabetes have an increased risk of pregnancy complications, especially in combination with pregestational overweight

BACKGROUND: Overweight and gestational diabetes are risk factors for pregnancy complications. We hypothesized that the metabolic impact of overweight on pregnancy outcome, would be different if it was combined with a predisposition for diabetes. The aim of this study was to compare the outcome of pregnancies in women with diabetes diagnosed later in life, to the outcome of pregnancies of women who

Determination of the Distance Between the Cytochrome and Dehydrogenase Domains of Immobilized Cellobiose Dehydrogenase by Using Surface Plasmon Resonance with a Center of Mass Based Model

Changes in the tertiary conformation of adsorbed biomolecules can induce detectable shifts (Δθr) in the surface plasmon resonance (SPR) angle. Here it is shown how to calculate the corresponding shifts in the adsorbate's center of mass (Δzavg) along the sensing surface normal from the measured Δθr. The novel developed model was used for determining the mean distance between the cytochrome (CYT) an

HIV treatment in Guinea-Bissau : room for improvement and time for new treatment options

Despite advances in the treatment quality of HIV throughout the world, several countries are still facing numerous obstacles in delivering HIV treatment at a sufficiently high quality, putting patients' lives in jeopardy. The aim of this status article is to give an overview of HIV treatment outcomes in the West African country, Guinea-Bissau, and to assess how newer treatment strategies such as l

Local delivery of minocycline-loaded PLGA nanoparticles from gelatin-coated neural implants attenuates acute brain tissue responses in mice

Background: Neural interfaces often elicit inflammatory responses and neuronal loss in the surrounding tissue which adversely affect the function and longevity of the implanted device. Minocycline, an anti-inflammatory pharmaceutics with neuroprotective properties, may be used for reducing the acute brain tissue responses after implantation. However, conventional administration routes require high

Mechanically ventilated patients exhibit decreased particle flow in exhaled breath as compared to normal breathing patients

Introduction: In this cohort study, we evaluated whether the particles in exhaled air (PExA) device can be used in conjunction with mechanical ventilation during surgery. The PExA device consists of an optical particle counter and an impactor that collects particles in exhaled air. Our aim was to establish the feasibility of the PExA device in combination with mechanical ventilation (MV) during su
