Resting-State Functional Magnetic Resonance Imaging for Brain Tumor Surgical Planning: Feasibility in Clinical Setting.

2019

The aim of this study was to introduce resting-state functional magnetic resonance imaging (rest-fMRI) capability for brain tumor surgical planning. rest-fMRI is an emerging functional neuroimaging technique potentially able to provide new insights into brain physiology and to provide useful information regarding brain tumors in preoperative and postoperative settings. rest-fMRI evaluates low-frequency fluctuations in the blood oxygen level–dependent signal while the subject is at rest during magnetic resonance imaging examination. Multiple resting-state networks have been identified, including the somatosensory, language, and visual networks, which are of primary importance for surgical pl…

Dark Spots in Trade Theory: Early Testing Attempts

2020

The beginnings of the economic theory correspond to philosophers’ attempts to explain why and how do countries trade with each other. Yet even more puzzling was the question how should countries trade? It is no surprise that despite the formidable developments of the theory in the last 200 years plus, there still are dark spots in the economics of trade. Globalization has rendered the issue even murkier. Beside the fact that international trade cannot be insulated from other economic domains, which makes it inadequate for experiments, but even testing itself is cumbersome. Only, evidence on such a complex field as international trade is by no means easy to come by.

Backcasting for desirable futures in Finnish forest-based firms

2020

Purpose In Finland, new forest-based sector (FBS) businesses are seen as important for the transition to the circular bioeconomy. The purpose of this study is to explore the transition of Finnish FBS companies to new business models. The aim is to understand how FBS companies define their ideal future states and related business models for the year 2030. Design/methodology/approach This study uses thematic interviews with managers from various FBS firms and companies from interfacing sectors. In the interviews, the key idea of backcasting was pursued when respondents discussed the desirable future states of their business. Findings The effort to achieve growth of the business and the appea…

Isolated in-vitro perfusion of pig hearts obtained from the abattoir: an alternative to animal experiments?

1994

Isolated pig hearts (German farm pigs) were characterized after global in-vivo ischaemia as a potential alternative to in-vivo animal studies. Hearts were harvested from adult farm swine at the abattoir 10.3 +/- 2.1 min after incision of the carotid artery. They were immediately perfused and thereafter stored in ice-cold cardioplegic (St Thomas's) solution. After 38 +/- 3 min, retrograde perfusion was started with oxygenated pig blood (37 degrees C; 5000 U Heparin.l-1; pH 7.38 +/- 0.1; 11 mmol glucose.l-1) at a flow rate of 85 ml.min-1 100 g-1 wet weight (gww-1) for 30 min (n = 10). Additionally, shortly after obtaining the hearts, ATP and CP content were measured by enzymatic tests in 10 p…

Biomechanical comparison between the modified rolling-hitch and the modified finger-trap suture techniques

2016

Purpose: The purpose of this study was to characterize the biomechanical effect of two grasping suture techniques used during ligament reconstruction: the modified rolling-hitch (MRH) and the modified finger-trap (MFT). Methods: Flexor profundus tendons were harvested from fresh pig hind-leg trotters. Each specimen was mounted on an electro-mechanic universal testing machine (Instron 3367). In half of all tendons (15 specimens), the suture was passed around the tendon following the MRH knot (Group 1). In the remaining half of all tendons (15 specimens), the suture was passed over a distance of 30 mm according to the MFT suture technique (Group 2). As per standard intra-operative technique, …

The Content of the Websites: Emergence of Intimate Cyberplaces

2017

On the basis of an interpretation of the content of the contrade’s websites, this chapter proposes that these communities unlock cyberspace through inhabiting cyberplaces. They local ise cyberspace, making it concrete and create intimacy by highlighting their history, special places, and maps of their district, announcing events and posting pictures of them, presenting and explaining their symbol ism, exhibiting emblems and artefacts, and by listing the names and showing pictures of community members and horses that have taken part in the palio. By constructing websites in such a way, the contrade inhabit cyberplaces that are characterised by intimacy and familiarity , as they present their…

Europe's offshore winds assessed with synthetic aperture radar, ASCAT and WRF

2020

Europe's offshore wind resource mapping is part of the New European Wind Atlas (NEWA) international consortium effort. This study presents the results of analysis of synthetic aperture radar (SAR) ocean wind maps based on Envisat and Sentinel-1 with a brief description of the wind retrieval process and Advanced Scatterometer (ASCAT) ocean wind maps. The wind statistics at 10 and 100 m above mean sea level (a.m.s.l.) height using an extrapolation procedure involving simulated long-term stability over oceans are presented for both SAR and ASCAT. Furthermore, the Weather Research and Forecasting (WRF) offshore wind atlas of NEWA is presented. This has 3 km grid spacing with data …

Simulation and Test of UAV Tasks With Resource-Constrained Hardware in the Loop

2021

Simulations are indispensable to reduce costs and risks when developing and testing algorithms for unmanned aerial vehicles (UAV) especially for applications in high risk scenarios like search and rescue (SAR) operations and post-disaster damage assessment. Many UAV applications require real-time tasks for which the timeliness of computations is fundamental. However, standard simulation tools are not guaranteed to run in sync with real-time events, leading to unreliable assessments of the ability of the target hardware to perform specific tasks. In this work we present a simulation and test system able to run UAV tasks on resource-constrained target hardware possibly adopted in these applic…
