Camera Pose Estimation with Unknown Principal Point

To estimate the 6-DoF extrinsic pose of a pinhole camera with partially unknown intrinsic parameters is a critical sub-problem in structure-from-motion and camera localization. In most of existing camera pose estimation solvers, the principal point is assumed to be in the image center. Unfortunately, this assumption is not always true, especially for asymmetrically cropped images. In this paper, w

Biosensing using arrays of vertical semiconductor nanowires : mechanosensing and biomarker detection

Due to their high aspect ratio and increased surface-to-foot-print area, arrays of vertical semiconductor nanowires are used in numerous biological applications, such as cell transfection and biosensing. Here we focus on two specific valuable biosensing approaches that, so far, have received relatively limited attention in terms of their potential capabilities: cellular mechanosensing and lightgui

Nonlinear Dynamic Output Feedback Stabilization of Moore-Greitzer Models with Quadratic Constraints

Here, we propose a new procedure for output feedback design for systems with nonlinearities satisfying quadratic constraints. It provides an alternative for the classical observer-based design and relies on transformation of the closed-loop system with a dynamic controller of particular structure into a special block form. Asymptotic stability is shown using Lyapunov theory with strictly positive

rhIGF-1/rhIGFBP-3 in Preterm Infants : A Phase 2 Randomized Controlled Trial

Objective: To investigate recombinant human insulin-like growth factor 1 complexed with its binding protein (rhIGF-1/rhIGFBP-3) for the prevention of retinopathy of prematurity (ROP) and other complications of prematurity among extremely preterm infants. Study design: This phase 2 trial was conducted from September 2014 to March 2016. Infants born at a gestational age of 230/7 weeks to 276/7 weeks

The production of geminates in Italian-dominant bilinguals and heritage speakers of Italian

This study examines cross-linguistic influence (CLI) in adult Italian-German bilinguals based on the production of gemination, a phenomenon that exists in Italian but not in German. We analyzed the spontaneous Italian speech of two groups of Italian-German bilinguals (heritage speakers of Italian and Italian-dominant bilinguals) and a monolingual Italian control group. The results show that the ge

Hydrogeophysical and hydrochemical characteristics of Pliocene groundwater aquifer at the area northwest El Sadat city, West Nile Delta, Egypt

Due to the overpopulation in the main cities and shortage of water in Egypt, finding new possible reclamation areas becomes an urgent necessity. The area northwest of El Sadat city can be considered one of the most promising new reclamation areas. This study focuses on detecting the groundwater aquifers, delineating the best localities to drill groundwater boreholes, and evaluation of the groundwa

Global, regional, and national burden of traumatic brain injury and spinal cord injury, 1990-2016 : a systematic analysis for the Global Burden of Disease Study 2016

BACKGROUND: Traumatic brain injury (TBI) and spinal cord injury (SCI) are increasingly recognised as global health priorities in view of the preventability of most injuries and the complex and expensive medical care they necessitate. We aimed to measure the incidence, prevalence, and years of life lived with disability (YLDs) for TBI and SCI from all causes of injury in every country, to describe

Minimal information for studies of extracellular vesicles 2018 (MISEV2018): a position statement of the International Society for Extracellular Vesicles and update of the MISEV2014 guidelines

The last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when w

This paper focuses on the use of the Compound Past (CP) found in a set of epistolary letters from the 18th and 19th centuries' Uruguay. It is claimed that the CP already at this time encodes situations that are conceptualized within a temporal frame of indeterminacy. All the cases of CP in 66 letters are analyzed according to its contexts – with or without temporal determinants; in colocational en

From initial hit to crystal optimization with microseeding of human carbonic anhydrase IX—A case study for neutron protein crystallography

Human carbonic anhydrase IX (CA IX) is a multi-domain membrane protein that is therefore difficult to express or crystalize. To prepare crystals that are suitable for neutron studies, we are using only the catalytic domain of CA IX with six surface mutations, named surface variant (SV). The crystallization of CA IX SV, and also partly deuterated CA IX SV, was enabled by the use of microseed matrix

Images of the North : An imagological analysis of Nordic noir book covers in Greece and Spain

Although Scandinavia is arguably peripheral in the global literary system, it nevertheless holds a surprisingly prominent position in the field of translation, Swedish and Danish being among the ten most translated languages in the world (Lindqvist, 2015). What literature is selected for translation and introduction into new linguistic contexts is not a coincidence, but has to do with economic fac

Atenolol versus losartan in children and young adults with Marfan's syndrome

BACKGROUND: Aortic-root dissection is the leading cause of death in Marfan's syndrome. Studies suggest that with regard to slowing aortic-root enlargement, losartan may be more effective than beta-blockers, the current standard therapy in most centers.METHODS: We conducted a randomized trial comparing losartan with atenolol in children and young adults with Marfan's syndrome. The primary outcome w
