CEP-stable few-cycle pulses with more than 190 μJ of energy at 100 kHz from a noncollinear optical parametric amplifier
(2017)Noncollinear optical parametric amplifiers (NOPAs) have become the leading technique for the amplification of carrier-envelope phase (CEP)-stable, few-cycle pulses at high repetition rate and high average power. In this ... -
Cerebrospinal Fluid Phosphate in Delirium after Hip Fracture
(2017)Aims: Phosphate is essential for neuronal activity. We aimed to investigate whether delirium is associated with altered phosphate concentrations in cerebrospinal fluid (CSF) and serum. Methods: Seventy-seven patients with ... -
Challenges for Risk and Security Modelling in Enterprise Architecture
(2019-11-19)From our experience cooperating with the Norwegian Armed Forces, we outline two interconnected challenges for modelling risk and security in an enterprise architecture: (1) modelling what is protected and why it is protected ... -
Challenges in Seafloor Imaging and Mapping With Synthetic Aperture Sonar
(2011)Synthetic aperture sonar (SAS) is emerging as an imaging technology that can provide centimeter resolution over hundreds-of-meter range on the seafloor. Although the principle of SAS has been known for more than 30 years, ... -
Challenges of Labelling Unknown Seabed Munition Dumpsites from Acoustic and Optical Surveys: A Case Study at Skagerrak
(2022-05-31)The disposal of unexploded ordnance (UXOs) at sea is a global problem. The mapping and remediation of historic UXOs can be assisted by autonomous underwater vehicles (AUVs) carrying sensor payloads such as synthetic aperture ... -
Change Detection Using Time and Look Angle Series of Geocoded TanDEM-X Staring Spotlight Images
(2021-03-26)This article describes the analysis of changes in time and look angle series of TanDEM-X (TDX) and TerraSAR-X (TSX) staring spotlight images over the regions around Kjeller near Oslo in Norway and the town Nikel in Russia ... -
Changes in dive behavior during sonar exposure in killer whales, pilot whales and sperm whales.
(2012)Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), ... -
Changes in fibrinogen availability and utilization in an animal model of traumatic coagulopathy
(2013)Background Impaired haemostasis following shock and tissue trauma is frequently detected in the trauma setting. These changes occur early, and are associated with increased mortality. The mechanism behind trauma-induced ... -
Changes in inoperability for interdependent industry sectors in Norway from 2012 to 2017
(2021-03)The purpose of this work has been to investigate changes in interdependencies between Norway's mainland industry sectors and how it might affect national security. To this end, the interdependencies were analysed by using ... -
Changes in intestinal microbiota composition and metabolism coincide with increased intestinal permeability in young adults under prolonged physiologic stress
(2017)The magnitude, temporal dynamics, and physiological effects of intestinal microbiome responses to physiological stress are poorly characterized. This study used a systems biology approach and a multiple-stressor military ... -
Characterization of (111)B and (211)B CdZnTe Substrates for HgCdTe Growth
(2019-06-13)We have studied state-of-the-art CdZnTe (211)B and (111)B substrates and compared them to each other and to substrates from an alternative vendor. The CdZnTe surface has been characterized both as-received and after growth ... -
Characterization of a compact 6-band multifunctional camera based on patterned spectral filters in the focal plane
(2014)In some applications of multi- or hyperspectral imaging, it is important to have a compact sensor. The most compact spectral imaging sensors are based on spectral filtering in the focal plane. For hyperspectral imaging, ... -
Characterization of airborne bacteria at an underground subway station
(2012)The reliable detection of airborne biological threat agents depends on several factors, including the performance criteria of the detector and its operational environment. One step in improving the detector's performance ... -
Characterization of the public transit air microbiome and resistome reveals geographical specificity
(2021-05-26)Background The public transit is a built environment with high occupant density across the globe, and identifying factors shaping public transit air microbiomes will help design strategies to minimize the transmission of ... -
Characterization of Variable Density 3D Printed Materials for Broadband GRIN Lenses
(2017)In this work we design, simulate, manufacture and measure blocks made of variable density plastic. The density is controlled through varying the size of small cubes at the intersections of a fine grid. This structure is ... -
Characterizing the dynamic range of a hyperspectral camera
(2021-04-12)The dynamic range of a hyperspectral camera can have a strong impact on the quality and integrity of the collected spectra. For the image sensor chip alone, the dynamic range is the ratio between the saturation level and ... -
Chemoselective O-acylation of hydroxyamino acids and amino alcohols under acidic reaction conditions: History, scope and applications
(2015)Amino acids, whether natural, semisynthetic or synthetic, are among the most important and useful chiral building blocks available for organic chemical synthesis. In principle, they can function as inexpensive, chiral and ... -
Chirped pulses sum frequency generation for deep-UV picosecond pulse shaping
(2012)We show by experiments and simulations that properly chirped laser pulses enable efficient and broadband sum frequency generation in nonlinear crystals. We achieved high energy, picosecond deep-UV pulses with spectral ... -
