Automatic video captioning is challenging due to the complex interactions in dynamic real scenes. A comprehensive system would ultimately localize and track the objects, actions and interactions present in a video and generate a description that relies on temporal localization in order to ground the visual concepts. However, most existing automatic video captioning systems map from raw video data

Dosimetric errors in a magnetic resonance imaging (MRI) only radiotherapy workflow may be caused by system specific geometric distortion from MRI. The aim of this study was to evaluate the impact on planned dose distribution and delineated structures for prostate patients, originating from this distortion. A method was developed, in which computer tomography (CT) images were distorted using the MR

Apolipoprotein M (ApoM) plasma levels have been reported to be associated with risk of venous thromboembolism (VTE) recurrence. However, the role of genetic alterations in the ApoM gene in VTE recurrence remains unknown. The aim of this study was to identify genetic aberrations in ApoM gene in VTE recurrence and their role in prediction of VTE recurrence in a prospective follow-up study of 1465 VT

To achieve significant improvements, there is a need for a systematic approach in Road Safety Management. The first step of such approach is to define the burden of road casualties in the country. Part of defining the burden is the monetary valuation of the prevention of a fatality accident. Such “values of statistical life” are derived in a number of countries, however, there is a large variation

This paper examines the influence of land fragmentation on the value ofvegetables produced in the Skopje and Southeastern regions of the Republic ofMacedonia. The analysis uses models such as a Cobb-Douglas production function as well as a General Linear Model. The findings support a negative and statistically significant impact of land fragmentation on the productivity and profitability of vegeta

A new method is presented for calculating optical properties within the framework of the self-consistent linear muffin-tin orbital (LMTO) band-structure theory. We show how Green's second identity along with the commutation relation between the position and Hamiltonian operators may be used to calculate, independently of the gauge, the velocity matrix elements required for optical properties. The

Rapporten avser att ge generella riktlinjer och exempel på hur fuktsäkra takkonstruktioner i trä kan byggas. En rad viktiga faktorer som påverkar fuktsäkerheten och risken för fukt- och mögelrelaterade skador presenteras. Rapporten avser även att fungera som ett verktyg och stöd för svenska trähustillverkare, statliga och kommunala tjänstemän som handlägger byggrelaterade ärenden samt byggherrar o

The paper presents results from a comparative study of selected biological and technical functions for thermal adaptability, which are based on an extensive literature review in biology and façade engineering. Several selected biological role models have been analysed in detail to identify their principles for dealing with thermal adaptation. These principles have been further abstracted through s

Denna debattartikel argumenterar för att socialt arbete och socialtjänst behöver utvecklas i förhållande till digitalisering. Som ett led i ett samarbetsprojekt mellan Lunds universitet och Helsingborg stad, finansierat av både Vinnova och Helsingborg stad, skriver företrädare för både universitet och stad en debattartikel i DN. Hur kan socialtjänsten utvecklas med hjälp av digitalisering - nu och

Recent research on the process of biological phosphorus removal in lab-scale treatment systems has indicated that: (i) the development of an actively poly?-accumulating bacterial community after the introduction of an anaerobic period may take at least 4 months; (ii) up to 80% of all aerobic bacteria isolated from these communities are able to accumulate polyP; (iii) polyP synthesized by the bacte

This paper reports on studies of cellular instability of lean hydrogen/air laminar premixed flames with an equivalence ratio of 0.6 at a 5 atm and a 25 atm pressure. Numerical simulations employing a detailed chemical kinetics mechanism and detailed transport properties are carried out to simulate the initial linear growth of instability as well as the nonlinear evolution of flames. At the initial

Leukotoxin is a well-known virulence factor of animal isolates of Fusobacterium necrophorum subspecies necrophorum, and is also expressed by animal isolates of subspecies funduliforme, whereas its presence in isolates from humans has not been fully established. In this study we found that the leukotoxin gene was present in all tested F. necrophorum isolates from humans. Three sequence variants wer

Many modern software applications have performance requirements, like mobile and embedded systems that must keep up with sensor data, or web services that must return results to users within an acceptable latency bound. For such applications, the goal is not to run as fast as possible, but to meet their performance requirements with minimal resource usage, the key resource in most systems being en
