SMSSVD : SubMatrix Selection Singular Value Decomposition

Motivation: High throughput biomedical measurements normally capture multiple overlaid biologically relevant signals and often also signals representing different types of technical artefacts like e.g. batch effects. Signal identification and decomposition are accordingly main objectives in statistical biomedical modeling and data analysis. Existing methods, aimed at signal reconstruction and deco

The consequences of saline irrigation treatments on soil physicochemical characteristics

When saline water is used to irrigate crops in arid environments, appropriate irrigation management should be applied to avoid negatively impacting soil characteristics. In this study, the effects of irrigating date palms with saline water (2.24 g l−1) on soil physicochemical characteristics such as the electrical conductivity (ECe), the pH of the saturated soil paste (pHe), the concentrations of

Convergence angle and dimple shape effects on the heat transfer characteristics in a rotating dimple-pin fin wedge duct

A numerical method is employed to study effects of convergence angle and dimple shape on flow structure and heat transfer under a rotating frame. The investigated convergence angles are 0.0°, 6.3°, and 12.7°. The dimple shapes are circular, streamwise-elliptical, and spanwise-elliptical. The rotation number ranges from 0.0 to 0.4. Computed flow structures and heat transfer are compared. Higher rot

When sharing platforms fix sellers' prices

While price-fixing on platforms can attract severe enforcement action, as shown by the Amazon poster case, a more nuanced picture emerges regarding the fixing of prices for sellers by sharing economy platforms. This article explores possible antitrust responses to such centralized platform-driven price-fixing. The article, first, provides an introduction to the sharing economy and pricing models o

Electronic Media Access and Use for Sexuality and Sexual Health Education Among Men Who Have Sex With Men in Four Cities in Tanzania

Background: Electronic media use is an important avenue for reaching stigmatized populations. We examined Internet access and use of sexually related electronic media among men who have sex with men (MSM) in 4 cities in Tanzania. Methods: A questionnaire was administered to 231 MSM in Dar es Salaam, Mwanza, Arusha, and Tanga regarding electronic media type, times of use, type of use and frequency

Pedestrian movement in smoke : Theory, data and modelling approaches

The understanding of pedestrian movement in smoke-filled environments is of significant importance in fire safety engineering applications. This chapter presents an overview of the main concepts concerning pedestrian movement in smoke, with a particular emphasis on the adverse effects that it can have on pedestrian evacuation. Several factors are discussed, including fire, pedestrian and environme

Late Weichselian to Holocene history of the Baltic Sea as reflected in ostracod assemblages

The study presents the first description and analysis of ostracod records from three sites cored in different parts of the Baltic Sea during the IODP Expedition 347, Baltic Sea Paleoenvironment. Our data present the first high-resolution ostracod records from the Late Weichselian and Holocene sediments collected across the Baltic Sea Basin. Using published data on modern ostracod species ecology o

Group leader and participant perceptions of Balancing Everyday Life, a group-based lifestyle intervention for mental health service users

Background: There exist few recovery and occupation-based interventions for mental health service users. Balancing Everyday Life (BEL) is a new occupation-based lifestyle intervention that was created to fill this need. Aim: To gain group leaders’ and participants’ perspectives of the BEL intervention content and format, including factors that helped, hindered, and could be improved. Methods: A co

THE HISTORY OF AFRICAN POVERTY BY NUMBERS : EVIDENCE AND VANTAGE POINTS

Poverty has a long history in Africa. Yet, the most conventional and influential history of African poverty is a very short one. As told by the World Bank, the history of poverty starts in the 1980s with the first Living Standard Measurement Study. This history of poverty by numbers is also a very narrow one. There is a disconnect between the theoretical and historical underpinnings of how academi

Numerical predictions of flow and heat transfer of film cooling with an internal channel roughened by crescent ribs

This study explores the effects of crescent ribs mounted in an internal cooling channel on the external adiabatic film cooling performance to evaluate the advantage of crescent ribs in gas turbine blade cooling. Three ribs including a transverse rib, a crescent rib concave to the stream-wise direction, and a crescent rib convex to the stream-wise direction are considered. For a fixed mainstream fl

On the Phase Behaviour of Soft Matter: Understanding Complex Interactions via Quantitative Imaging

A first lesson in physical chemistry invariably starts with an example of water existing in three states, or phases - gaseous (water vapour), liquid (water from the tap) and solid (ice cubes). Such phase transitions are easily observed, but their underlying cause is not so evident. Atoms and molecules are difficult to follow due to their minute size and rapid movements. So, in order to investigateThe effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. The first studied system comprises of thermosensitive microgels. These ar

Lipid sponge phase nanostructures as carriers for enzymes

Lipids are organic molecules vital for living organisms. They are part of cell membranes and provide an important energy reserve once they are digested by our body. They are most commonly known as fats and oils. Some important so-called polar lipids are amphiphilic molecules, which means they have a head group that is water ‘loving’ (hydrophilic) and a hydrocarbon tail is water ‘hating’ (hydrophobNonlamellar lipid liquid crystalline phases have many potential applications, such as for drug delivery, protein encapsulation or crystallization. Lipid liquid crystalline sponge phase (L3) has so far not been very much considered in these applications, in spite of apparent advantages in terms of its flexibility and capacity of forming large aqueous pores able to encapsulate large bioactive molecu

Behind the “Failed Revolution” : Becoming Patriots, or the Work of Shame in Belarusian Protests

This article looks at the politics of shame in relation to the suppressed protests of December 2010 that challenged the re-election of Aliaksandr Lukashenka as president of Belarus (1994–present). My empirical data consist of independent media publications, blog posts, and interviews that speak of “shame” as an emotional response to the protest, its aftermath, and its general context. The article

The genetic architecture of type 2 diabetes

The genetic architecture of common traits, including the number, frequency, and effect sizes of inherited variants that contribute to individual risk, has been long debated. Genome-wide association studies have identified scores of common variants associated with type 2 diabetes, but in aggregate, these explain only a fraction of the heritability of this disease. Here, to test the hypothesis that

On the search for industry-relevant regression testing research

Regression testing is a means to assure that a change in the software, or its execution environment, does not introduce new defects. It involves the expensive undertaking of rerunning test cases. Several techniques have been proposed to reduce the number of test cases to execute in regression testing, however, there is no research on how to assess industrial relevance and applicability of such tec
