Objective: Oxygen enhanced pulmonary MRI is a promising modality for functional lung studies and has been applied to a wide range of pulmonary conditions. The purpose of this study was to characterize the oxygen enhancement effect in the lungs of healthy, never-smokers, in light of a previously established relationship between oxygen enhancement and diffusing capacity of carbon monoxide in the lun

Presents a microphone array system for use in handsfree mobile telephone equipment. The array is based on a fast and efficient “on-site” and “self-calibration” scheme. The performance in suppressing the interior car cabin noise and the far-end speech is approximately 17 dB, respectively, while maintaining the near-end speaker level. The near-end signal is almost undistorted. The performance of two

A novel adaptive beamformer employing recursively updated soft constraints for acoustic speech enhancement is proposed. The beamformer operates in a subband structure to allow time-frequency operation for each channel. As such, the processing can be viewed as a combination of weighted spatial and temporal filters. The major benefit of this recursive soft constrained beamformer is that it allows th

The aim of this study was to evaluate the effects of vitamin K1 on various vitamin K-dependent proteins in critically ill patients with prolonged Owren PT. We included critically ill non-bleeding adult patients without liver failure or anticoagulation treatment, with Owren PT > 1.2, who were prescribed intravenous vitamin K1. Blood was drawn at baseline and at 20–28 h after vitamin K1 administrati

The question whether a single extreme climate event, such as a hurricane or heatwave, can be attributed to human induced climate change has become a vibrant field of research and discussion in recent years. Proponents of the most common approach (probabilistic event attribution) argue for using single event attribution for advancing climate policy, not least in the context of loss and damages, whiThe question whether a single extreme climate event, such as a hurricane or heatwave, can be attributed to human induced climate change has become a vibrant field of research and discussion in recent years.

The paper analyses dwell time delays for commuter trains in Stockholm andTokyo. In both cities, small dwell time delays of at most five minutes makeup around 90% of the total delays. Therefore, it is valuable to understandand deal with these disturbances. To this end, we use high resolution data ondwell times and passenger counts from both countries over the last severalyears. We find that these d

The objective was to clarify whether and how it is possible to detect, track and identify with an EO/IR (electro optical/infrared) sensor. Moreover, the sight of robotic system 90 was tested in order to clarify the possibilities of using it as a sensor. The sight has a field of view of 3x4° with the TV camera and 4x6° with the IRV camera. Therefore, the project focused on a moving sensor, in order

Purpose: The purpose is to provide a nuanced understanding of organisational cultural differences, obstacles associated with the human integration process and management strategies to overcome them. Theoretical Framework: Organisational cultural differences are treated as stemming largely from the organisation’s task environment, influenced by industry and function. Human integration is the proce

This study explores the idea of flat organizational structures, which are gaining popularity due to their capacity to foster innovation and collaboration. Nevertheless, social interactions inside these organizations can still result in the emergence of social hierarchies, and some employees may hold positions of greater authority and status than others. Therefore, we examine how social hierarchies

It is a well-recognized fact that a city will continue to grow whether or not it is desirable. Growth is not something that can be stopped, only contained and influenced. In that way, there is a need for new concepts and approaches to urban space planning and this could be in the form of vertical cities. The tall building is indeed a vertical progression of a horizontal city and should be consid

As algorithmically-driven content moderation has become a common feature of social media platforms to suppress communications deemed undesirable, scholars have started to examine users’ relations to algorithmic systems and problems of machine bias and governmentality. While most researchers have focused on the negative aspects of censorship, few have explored the possibilities of users to oppose a

III-V compound materials have long been used in RF applications in high-electron-mobility-transistors (HEMTs) and bipolar-junction-transistors (BJTs). Now, III-V is also being viewed as a material candidate for replacing silicon in the n-channel in CMOS processes for increased drive currents and reduced power consumption in future nodes. Another alternative to increase the drive current is to use III-V compound materials have long been used in RF applications in high-electron-mobility-transistors (HEMTs) and bipolar-junction-transistors (BJTs).

The role of market-specific factors in driving business model adaptation during international expansion has received limited scholarly attention, particularly among early-stage start-ups in the agricultural biotechnology industry. Therefore, this study asks how market-specific factors influence business model adaptation during internationalization in the agricultural biotechnology sector, thereby
