We report on the first time-resolved small-angle neutron scattering (SANS) study of the structural relaxation from a shear-induced aligned state back to the isotropic state in a system of giant wormlike reverse micelles. The micelles are formed by lecithin and small amounts of water in cyclohexane. A liquid sample with the micellar volume fraction phi = 0.3 was exposed to a steady shear of (gamma)
The balance between exploration and exploitation is one of the key problems of action selection in Q-learning. Pure exploitation causes the agent to reach the locally optimal policies quickly, whereas excessive exploration degrades the performance of the Q-learning algorithm even if it may accelerate the learning process and allow avoiding the locally optimal policies. In this paper, finding the o
Since the working environment act was passed in 1991 employers in Sweden are to plan and control the working environment conditions in workplaces. They are responsible for organized rehabilitation at the workplace including the development of rehabilitation plans and a plan for interventions in order for a sick-listed client to be able to return to work.The aim of this study was to describe employ
In this chapter, speech enhancement and echo cancellation for hands-free mobile telephony are discussed. A number of microphone array methods have been tested and results from car measurements are given. Traditional methods such as linearly constrained beamforming and generalized sidelobe cancelers are discussed as well as array gain optimization methods. An in situ calibrated method which gives a
Spectral properties of the weighted Laplace operator in the presence of fractal boundaries are numerically investigated for both Neumann and Dirichlet boundary conditions. This corresponds to the characterization of heat and mass transport in microchannels with irregular and rough surfaces induced by the microfabrication process. The axial velocity field with no-slip boundary conditions, represent
This work presents a digital calibration technique in continuous-time (CT) delta-sigma (Δ Σ) analog to digital converter. The converter is clocked at 144 MHz with a low oversampling ratio (OSR) of only 8. Dynamic element matching is not efficient to linearize the digital to analog converter (DAC) when the OSR is very low. Therefore, non-idealities in the outermost multi-bit feedback DAC are measur
Pancreatic cancer has a dismal prognosis and there is an increasing and unmet need to identify better diagnostic and therapeutic targets in order to ameliorate the course of the disease. HMGB1, a nuclear DNA-binding protein that acts as a transcription factor, is currently in the limelight. HMGB1 exhibits a dual role in pancreatic cancer; when intracellular, it acts as an anti-tumor protein stabil
The structure tensor is a powerful tool describing the local intensity structure of an image or image sequence. In this paper we give a model for the noise distribution of the components of the tensor. In order to do so we have also investigated some properties of the gamma distribution. We show that, given an input image corrupted with Gaussian noise, the noise in the structure tensor can be modThe structure tensor is a powerful tool describing the local intensity structure of an image or image sequence.

Malignant melanoma is one of the most aggressive tumors which often gives metastasis to distant organs thereby limiting the chances of survival. Brain metastasis occurs in nearly half of the advanced tumors. In order to improve outcome early diagnosis is important. The discovery and better understanding of genetic and epigenetic changes is essential for developing new effective therapies, which ca
Several studies demonstrate the value of residents’ voices in the place branding process, however, relatively little is known about how residents experience participating in place branding campaigns and the consequences for place identity. This chapter explores the question of whether participatory branding initiatives could potentially lead to more inclusionary representational spaces in the city

Infrastructure barriers and high costs of alternative sustainable fuels constrain the global logistics sector's transition to decarbonization. This research investigates how logistics providers establish institutional trust in the 'Book and Claim' service, where the environmental benefits of sustainable fuels are spatially decoupled from the physical transport of goods.

Aspects of spatial and temporal rainfall variability and rainfall analysis in relation to some water management problems are surveyed and discussed. It is concluded that relevant modelling of hydrological processes in which the rainfall is a driving force is vital with respect to possibilities of finding solutions to increasing environmental problems following urbanization and industrialization. H
Spring water, however, is often formed in complex geological formations and therefore it is difficult to determine the catchment area contributing to the flow. The Sayanokami spring, located in western part of Fukuoka City, Japan, is such a spring and an important water resource for the local agriculture. In order to better understand the hydrological properties of infiltration and groundwater pro
There is a growing interest in probabilistic numerical solutions to ordinary differential equations. In this paper, the maximum a posteriori estimate is studied under the class of ν times differentiable linear time-invariant Gauss–Markov priors, which can be computed with an iterated extended Kalman smoother. The maximum a posteriori estimate corresponds to an optimal interpolant in the reproducin
In this paper, a life cycle assessment (LCA)-based sustainability assessment framework is developed to estimate the environmental impact of production processes. The framework provides a methodical, context-independent, approach to carry out LCA studies. The framework sets guiding principles for products and key performance indicators (KPIs) selection and the associated data requirements in a reco
The philosophy of Plotinus plays a contradictory role in Giorgio Agamben’s corpus. He comments on Plotinus in a lapidary fashion in several articles and essays before commencing the Homo Sacer series, where he undertakes a longer and more ambiguous analysis of Plotinus in Opus Dei and The Use of Bodies. In Opus Dei, Agamben develops the brief criticism of Plotinus he proposed in The Kingdom and th
This paper investigates a Swedish house manufactures building system regarding the documentation and information structures. The aim is to evaluate how product modeling technology can be used to facilitate product customization. By dividing the product in four different views the complexity of the product can be reduced and each view represent the interest of customer, engineering, production and
