A new library called LIBRETA for the evaluation of electron repulsion integrals (ERIs) and their first and second derivatives over segmented and contracted Gaussian functions is developed. Our LIBRETA is optimized from three aspects: (1) The Obara-Saika, Dupuis-Rys-King, and McMurchie-Davidson method are all employed. The recurrence relations involved are optimized by tree-search for each combination of angular momenta, and in the best case, 50% of the intermediates can be eliminated to reduce the computational cost...

Societies worldwide are investing considerable resources into the safe development and use of nanomaterials. Although each of these protective efforts is crucial for governing the risks of nanomaterials, they are insufficient in isolation. What is missing is a more integrative governance approach that goes beyond legislation. Development of this approach must be evidence based and involve key stakeholders to ensure acceptance by end users. The challenge is to develop a framework that coordinates the variety of actors involved in nanotechnology and civil society to facilitate consideration of the complex issues that occur in this rapidly evolving research and development area...

Objective: Online portals provide patients with access to their test results, but it is unknown how patients use these tools to manage results and what information is available to promote understanding. We conducted a mixed-methods study to explore patients' experiences and preferences when accessing their test results via portals. Materials and Methods: We conducted 95 interviews (13 semistructured and 82 structured) with adults who viewed a test result in their portal between April 2015 and September 2016 at 4 large outpatient clinics in Houston, Texas...

Desert vegetation plays significant roles in securing the ecological integrity of oasis ecosystems in western China. Timely monitoring of photosynthetic/non-photosynthetic desert vegetation cover is necessary to guide management practices on land desertification and research into the mechanisms driving vegetation recession. In this study, nonlinear spectral mixture effects for photosynthetic/non-photosynthetic vegetation cover estimates are investigated through comparing the performance of linear and nonlinear spectral mixture models with different endmembers applied to field spectral measurements of two types of typical desert vegetation, namely, Nitraria shrubs and Haloxylon...

Assessing ageing infrastructure is a critical challenge for civil engineers due to the difficulty in the estimation and integration of uncertainties in structural models. Field measurements are increasingly used to improve knowledge of the real behavior of a structure; this activity is called structural identification. Error-domain model falsification (EDMF) is an easy-to-use model-based structural-identification methodology which robustly accommodates systematic uncertainties originating from sources such as boundary conditions, numerical modelling and model fidelity, as well as aleatory uncertainties from sources such as measurement error and material parameter-value estimations...

Clinical nurse leader (CNL)-integrated care delivery is an emerging nursing model, with growing adoption in diverse health systems. To generate a robust evidence base for this promising nursing model, it is necessary to measure CNL practice to explicitly link it to observed quality and safety outcome improvements. This study used a modified Delphi approach with an expert CNL panel to develop and test the face, content, and construct validity of the CNL Practice Survey instrument.

Given the popularity of dental implants, determining their prognosis is an integral component of dental practice. An accurate prognosis is crucial to development of an appropriate treatment plan and may require alterations as overall status or the status of implants or natural teeth change. The importance of an established set of factors for determining implant prognosis would be highlighted in dentist-patient communication and in interdisciplinary collaboration. The main objective of the proposed prognostication system is short- and long-term success of dental implants...

InGaAs/InP single-photon detectors (SPDs) are the key devices for applications requiring near-infrared single-photon detection. The gating mode is an effective approach to synchronous single-photon detection. Increasing gating frequency and reducing the module size are important challenges for the design of such a detector system. Here we present for the first time, to the best of our knowledge, an InGaAs/InP SPD with 1.25 GHz sine wave gating (SWG) using a monolithically integrated readout circuit (MIRC)...

A calibration method based on homogeneous material for correcting laser-induced breakdown spectroscopy (LIBS) measurement-error bias in the case of dust pollution under laboratory conditions is proposed. The measured plasma spectra of the sample can be corrected by measuring the spectral integral of the homogeneous material. Thus, we can effectively minimize the dust pollution effect on LIBS and guarantee its precision. Results show that the mean absolute errors of CaO, MgO, Fe2O3, Al2O3, and SiO2 in cement samples are decreased notably from 1...

The widespread use of oaths at medical commencements is a recent phenomenon of the late 20th century. While many are referred to as "Hippocratic," surveys have found that most oaths are modern, and the use of unique oaths has been rising. Oaths taken upon entry to medical school are even more recent, and their content has not been reported. The authors surveyed all Association of American Medical Colleges member schools in the United States and Canada in 2015 and analyzed oath texts. Of 111 (70.2%) responses, full texts were submitted for 80 commencement and 72 white coat oaths...

Background The study examines two meso-strategic cancer networks, exploring to what extent collaboration can strengthen or hamper network effectiveness. Unlike macro-strategic networks, meso-strategic networks have no hierarchical governance structures nor are they institutionalised within healthcare services' delivery systems. This study aims to analyse the models of professional cooperation and the tools developed for managing clinical practice within two meso-strategic, European cancer networks. Methods Multiple case study design based on the comparative analysis of two cancer networks: Iridium, in Antwerp, Belgium and the Institut Català d'Oncologia in Catalonia, Spain...

Coronary artery disease (CAD) associated with left ventricular systolic dysfunction is a condition related to poor prognosis. There is a lack of robust evidence in many aspects related to this condition, from definition to treatment. Ischemic cardiomyopathy is a spectrum ranging from stunned myocardium associated with myocardial fibrosis to hibernating myocardium and repetitive episodes of ischemia. In clinical practice, relevance lies in identifying the myocardium that has the ability to recover its contractile reserve after revascularization...

Hui Gao, Yang Li, Lianwei Chen, Jinjin Jin, Mingbo Pu, Xiong Li, Ping Gao, Changtao Wang, Xiangang Luo, Minghui Hong
The quasi-Talbot effect of orbital angular momentum (OAM) beams, in which the centers are placed in a rotationally symmetric position, is demonstrated both numerically and experimentally for the first time. Since its multiplication factor is much higher than the conventional fractional Talbot effect, the quasi-Talbot effect can be used in the generation of vortex beam arrays. A metasurface based on this theory was designed and fabricated to test the validity of this assumption. The agreement between the numerical and measured results suggests the practicability of this method to realize vortex beam arrays with high integrated levels, which can open a new door to achieve various potential uses related to optical vortex arrays in integrated optical systems for wide-ranging applications...

With increasing accessibility and advancements in abdominal imaging modalities, the incidence of pancreatic neuroendocrine neoplasms has increased steadily during the past few decades. By definition, neuroendocrine neoplasms of the pancreas show neuroendocrine differentiation, but they represent a broad and heterogeneous group of neoplasms with diverse clinical and pathological characteristics. The majority of pancreatic neuroendocrine neoplasms can be classified as well-differentiated pancreatic neuroendocrine tumours (PanNETs) or poorly differentiated pancreatic neuroendocrine carcinomas (PanNECs)...

BACKGROUND: Integrated reminders within clinical systems have become more prevalent due to the use of electronic health records and evidence demonstrating an increase in compliance within practice. Clinical reminders are assessed for effectiveness on an individual basis, rather than in combination with existing prompts for other conditions. The growing number of prompts may be counter-productive as healthcare professionals are increasingly suffering from "reminder fatigue" meaning many reminders are ignored...

Anemia is a common complication of chronic kidney disease (CKD) and a predictor of increased mortality. This project integrated erythropoietin-stimulating agent (ESA) with CKD care under one practice setting, co-managing anemia with CKD while reducing frequency of office visits in a rural setting. Patients self-administered their weekly dosage of erythropoietin with monthly follow-ups. As a result, office visits decreased by 56% for patients with CKD Stage 4 and by 54% for patients with CKD Stage 5.

The controversy surrounding the different interpretations on the integrality of therapeutic and pharmaceutical care has led to the delimitation of its scope by a law, but the issue has not been completely pacified. As a contribution to this debate, we aim to discuss the challenges to ensure the integrality of the therapeutic and pharmaceutical care, based on a conceptual approach on the meanings of integrality in the Brazilian Unified Health System (SUS). We identified important challenges to ensure the integrality of the therapeutic and pharmaceutical care in the SUS...
