An exhaustive and simple method for dispersion flattening in double-clad single-mode fibers is presented. The idea is to generate all such fibers with a certain cutoff wavelength and then find, by one-dimensional minimization and direct inspection, fibers yielding minimum dispersion. As examples, the root mean square chromatic dispersion over the wavelength range (1.25, 1.60 mum) is minimized for

The soft color interaction model (SCI) as an add-on to standard perturbative QCD describes diffractive processes by allowing for additional soft color-octet exchanges below the conventional threshold for parton showering. We discuss how diffractive and inclusive event samples for diffractive hard processes can be obtained from a Monte Carlo in a unified way for pp → p[W± +X]p as an example, and di

Objective: The aims of the present study were to evaluate the role of the gap junction protein beta-2 gene (GJB2), encoding connexin 26 (Cx26), in children with moderate to profound prelingual nonsyndromic sensorineural hearing impairment (HI) and to investigate the carrier frequencies of the GJB2 gene mutations in a control population in Northern Finland. Methods: Mutation analysis was performed

This article offers a comparative analysis of representations of Russia in contemporary Polish and Swedish documentary films. In both countries, images of Russia are shaped by deeply rooted political and historical associations. Over the past decade, Polish documentaries have shown a noticeable shift towards new ways of addressing Russia, largely driven by a younger generation of filmmakers who ha

In the description of the production properties of gauge bosons (W±, Z0, γ*) at colliders, the lowest-order graph normally is not sufficient. The contributions of higher orders can be introduced either by an explicit order-by-order matrix-element calculation, by a resummation procedure or by a parton-shower algorithm. Each approach has its advantages and disadvantages. We here introduce a method t

Aleksander Giwercman är forskargruppsledare för den här forskargruppenOur research focuses on clinical and epidemiological aspects of gene-environment interaction in relation to human reproductive function. The clinical base of our research is closely linked to the Reproductive Medicine Centre at Skåne University Hospital, Malmö. This enables us to study both male and female reproduction, separately and in combination. Some important subareas of research include spe

Pufendorfinstitutet är ett tvärvetenskapligt institut med syfte att stimulera till samarbete mellan forskare från olika discipliner inom Lunds universitet.

The sports industry is one of the most challenging and constantly evolving industries, yet simultaneously, the smaller and medium-sized clubs face a severe challenge of competing against the biggest and best-known brands in the world. The sports literature is limited to marketing and studying global mega-brands; this thesis addresses the gap in strategic management literature concerning both sport

Humanistiska och teologiska fakulteterna bedriver en bred och varierad verksamhet inom forskning och utbildning som i vid mening syftar till att förstå människan som kulturell och samhällelig varelse. Vi forskar och utbildar inom områden som behandlar kulturmöten, språk, historia, etik, religion, filosofi, konst, musik, litteratur och annat som formar och definierar kulturerna.The Joint Faculties of Humanities and Theology provide research and education in a broad range of subjects, ranging from cultural sciences, history, philosophy, archaeology, languages and literature to theology and religious studies.
