We provide an analysis of a randomly grown 2-d network which models the morphological growth of dendritic and axonal arbors. From the stochastic geometry of this model we derive a dynamic graph of potential synaptic connections. We estimate standard network parameters such as degree distribution, average shortest path length and clustering coefficient, considering all these parameters as functions
Satellite remote sensing, with its unique synoptic coverage capabilities, can provide accurate and immediately valuable information on fire analysis and post-fire assessment, including estimation of burnt areas. In this study the potential for burnt area mapping of the combined use of Artificial Neural Network (ANN) and Spectral Angle Mapper (SAM) classifiers with Landsat TM satellite imagery was
Ecosystem services inherently involve people, whose values help define the benefits of nature's services. It is thus important for researchers to involve stakeholders in ecosystem services research. However, a simple and practicable framework to guide such engagement, and in particular to help researchers anticipate and consider key issues and challenges, has not been well explored. Here, we use e
Surface waters can contain a diverse range of organic pollutants, including pesticides, pharmaceuticals and industrial compounds. While bioassays have been used for water quality monitoring, there is limited knowledge regarding the effects of individual micropollutants and their relationship to the overall mixture effect in water samples. In this study, a battery of in vitro bioassays based on hum
The photolysis rates of HCHO, DCDO, CH3CHO, and CH 3CDO are studied by long-path FTIR spectroscopy in natural tropospheric conditions at the European Photoreactor Facility (EUPHORE) in Valencia, Spain. Average relative photolysis rates jHCHO/j DCDO = 3.15 ± 0.08 and jCH3CHO/jCH3CDO = 1.26 ± 0.03 are obtained from three days of experiments for each reaction in the period June 17 to July 7, 2006.
Objectives HPV self-sampling is an option for cervical screening. The aim of this randomised study was to investigate the compliance, prevalence of HPV, and prevalence of severe dysplasia in a vaginal self-sampling group in comparison to cervical samples collected by midwives (control arm). The hypothesis was that there would be no difference between vaginal self-sampling and cervical sampling to
Doxorubicin (DOX) is a cornerstone drug in the treatment of osteosarcoma. However, achieving sufficient concentration in the tumor tissue after systemic administration with few side effects has been a challenge. Even with the most advanced nanotechnology approaches, less than 5% of the total administered drug gets delivered to the target site. Alternatives to increase the local concentration of DO
Background and purpose: Radiation therapy treatment planning is a manual, time-consuming task that might be accelerated using machine learning algorithms. In this study, we aimed to evaluate if a triplet-based deep learning model can predict volumetric modulated arc therapy (VMAT) dose distributions for prostate cancer patients. Materials and methods: A modified U-Net was trained on triplets, a co
Purpose: To analyse and compare the number and interval of anti-vascular endothelial growth factor (anti-VEGF) injections in neovascular age-related macular degeneration (nAMD), as well as the visual development in patients followed up for one to three years in clinical practice and during different index periods. Methods: This observational study included treatment-naïve eyes with nAMD from the S
BACKGROUND Valid and reliable assessment of skills is essential for improved and evidence-based training concepts. In a recent study, we presented a novel tool to assess procedural skills in resuscitative endovascular balloon occlusion of the aorta (REBOA), REBOA-RATE, based on international expert consensus. Although expert consensus is a strong foundation, the performance of REBOA-RATE has not b
In this study, a linear discriminant analysis (LDA) - based nomenclature system have been used for the classification of groundwater samples in a coastal aquifer. The capability of three models (7 hlr, 7 M conc, and Greater molar conc) in determining the water types has been investigated. The results show that Ca-HCO3, Na-Cl, and Na-HCO3; and Ca-HCO3, Na-HCO3, and Na-Cl are the three dominant wate
Gut-associated lymphoid tissues (GALT) serve as key priming sites for intestinal adaptive immune responses. Most of our understanding of GALT function and development arises from studies in mice. However, the diversity, structure and cellular composition of GALT differs markedly between mammalian species and the developmental window in which distinct GALT structures develop in large mammals remain
The preservation of labile biomolecules presents a major challenge in chemistry, and deep eutectic solvents (DESs) have emerged as suitable environments for this purpose. However, how the hydration of DESs impacts the behavior of proteins is often neglected. Here, we demonstrate that the amino acid environment and secondary structure of two proteins (bovine serum albumin and lysozyme) and an antib
Background: Takotsubo syndrome (TS) is a life-threatening acute heart failure syndrome without any evidence-based treatment options. No treatment for TS has been examined in a randomized trial. Study design and objectives: BROKEN-SWEDEHEART is a multicenter, randomized, open-label, registry-based 2 × 2 factorial clinical trial in patients with TS designed to test whether treatment with adenosine a
Background: Acute ischemic lesions are challenging to detect by conventional computed tomography (CT). Virtual monoenergetic images may improve detection rates by increased tissue contrast. Purpose: To compare the ability to detect ischemic lesions of virtual monoenergetic with conventional images in patients with acute stroke. Material and Methods: We included consecutive patients at our center t
Background and purpose — The EQ-5D is a patient-reported outcome measure (PROM). To make priorities and allocate resources between patients and surgical procedures it is necessary to evaluate outcome differences, which is why comparing PROMs between registers is important. We compared EQ-5D data and the follow-up rate for selected diag-noses reported to Swedish orthopedic registers before and 1 ye
