We present a new method for manufacturing complex-valued harmonic morphisms from a wide class of Riemannian Lie groups. This yields new solutions from an important family of homogeneous Hadamard manifolds. We also give a new method for constructing left-invariant foliations on a large class of Lie groups producing harmonic morphisms.

How truck drivers spend their time is crucial to the profitability of motor carriers. However, the aspect of time has been marginally addressed in industry practice and academic literature on motor-carrier strategies and operations. Given the importance of the drivers in transport operations, the purpose of this article is to outline how driver time in motor-carrier operations can be measured usin

Nuclei with a central region of low nucleonic density, "bubble" nuclei, are studied. In particular, the possibility of bubbles in deformed nuclei is discussed, concentrating on experimentally accessible light nuclei. Utilizing the relativistic mean field (RMF) model we find favorable candidates in the prolately deformed Ne-24 nucleus and the mirror nuclei Si-32 and Ar-32 with oblate shapes.

In trying to understand any aspect surrounding the success and failure of information systems (IS) practice, concepts of organizational analysis become increasingly important. Many issues arise and must be dealt with when an information system is to be developed and implemented. In order to avoid information system failures, information system analysts should adopt an approach that exploits the in

Aim. - To explore the association between baseline levels of insulin-like growth-factor-binding protein-1 (IGFBP-1), a marker of insulin sensitivity, and the development of type 2 diabetes or impaired glucose tolerance (IGT) in a specifically defined middle-aged population. Methods. - This cross-sectional population-based screening study was conducted in 1989-1990 and included baseline data for 66

Todorov´s distinction between theoretical genres and historical genres are logically analyzed, the first being classes, the second cultural, social facts. The theoretical genres cannot, according to Todorov, be falsified or verified. This is on account of the rule saying that the language of object and the metalanguage must not be mixed. But this mixing is always present in ordinary language, in l

A new version of the stream cipher Grain-128 is proposed. The new version, Grain-128a, is strengthened against all known attacks and observations on the original Grain-128, and has built-in support for optional authentication. The changes are modest, keeping the basic structure of Grain-128. This gives a high confidence in Grain-128a and allows for easy updating of existing implementations.

Background: Intracerebral infections after deep brain stimulation (DBS) are rare. The published material is limited to 2 case reports. A review of 20 publications of 3,818 patients focusing on complications of DBS did not reveal one single case. For that reason, we decided to present our own experience of 4 patients with this complication. Objectives: To analyze and present our material regarding

We show that a maximum-weight triangle in an undirected graph with n vertices and real weights assigned to vertices can be found in time O(n(omega) + n(2+o(1))), where omega is the exponent of the fastest matrix multiplication algorithm. By the currently best bound on omega, the running time of our algorithm is O(n(2.376)). Our algorithm substantially improves the previous time-bounds for this pro

Despite a broad theoretical literature on multidimensional inequality and a widespread belief that welfare is not synonymous to income - not the least in a developing context - empirical inequality examinations rarely include several welfare attributes. We explore three techniques on how to evaluate multidimensional inequality using Zambian household data on consumption, education, health and land

The logic of the two principal ways of defining a genre - the classificatory and the historical is described. The problems concerning the classificatory definitions are analyzed. The distinction natural language and meta-language is evoked,and the fact that natural languages is defying this distinction,always mixing the levels,the classificatory genres do not. The historical genres belong to the n

Summertime measurements of CO2 and CH4 fluxes were carried out over a range of high-arctic ecosystem types in the valley Zackenbergdalen since 1996 using both chamber and eddy covariance methodology. The net ecosystem CO2 exchange and CH4 flux data presented reveal a high degree of inter-annual variability within the dominant vegetation types in the valley, but also show distinct differences betwe

This paper takes issue with a recent proposal due to Shogenji (Synthese 184:29-48, 2012). In his paper, Shogenji introduces J, a normatively motivated formal measure of justification (and of confirmation), and then proceeds to recruit it descriptively in an explanation of the conjunction fallacy. We argue that this explanation is undermined by the fact that it cannot be extended in any natural way

In Sweden and in other countries, building owners are encouraged to help reduce energy consumption, both in order to contribute to national energy saving goals and, in terms of their own interests, to reduce the costs of heating and operation of the building. However, it is important to pursue the most optimal strategy available so as to achieve cost-effective energy usage while simultaneously mai

Well-preserved fossil eggs and eggshell fragments from the Pliocene Apolakkia Formation of Rhodes (Greece) are described. The eggs were found in-situ in a clutch. They are sub- spherical with lengths of 53-60 mm and widths of about 40 mm. All eggs are diagenetically compressed and their original diameters are estimated at 45-50 mm. The eggshells are 0.3-0.5 mm thick, partly re-crystallized, but wi
