In an international perspective the Russian children s library is a unique institution, being solely committed to children up to 14 years of age. In Russia of today it is, however, being exposed to hard pressure as the economical and social conditions have changed dramatically since the collapse of the USSR. My interest lies in examining this change of living conditions for the children s librarie

Color dispersion, i.e., the dependency of refractive index of any transparent material on the wavelength of light, has important consequences for the function of optical instruments and animal eyes. Using a multi-objective goal attainment optimization algorithm, a dispersion model was successfully fitted to measured refractive indices of various ocular media and the longitudinal chromatic aberrati

Detailing how the cosmological environment surrounding a galaxy (large-scale structure) influences the local star-forming regions (small-scale structure) in the galaxy, and viceversa, remains an open question in the field of galaxy formation and evolution. Observations of massive star-forming galactic discs at extremely high redshifts have made this problem all the more pressing, putting current s

This article is over 5 years old, and the information may therefore be outdated. When Lund University switched to digital teaching there were many challenges both for the teaching staff and students. How exams and assessment were to be conducted now that the students were not on-site was an important question and a very difficult challenge. The existing tools for digital on-campus exams were teste

A former student had heard that our senior lecturer in statistics, Pierre Carbonnier was about to retire after this semester. Would we do a feature on him? The student remembered him fondly and added that his mother had also had Pierre as a teacher and thought he was pretty awesome. Few, if any statistics teachers can claim to have reached and inspired more students than Pierre Carbonnier, who has

Recent advances in experimental plant biology have led to an increased potential to investigate plant development at a systems level. The emerging research field of Computational Morphodynamics has the aim to lead this development by combining dynamic spatial experimental data with computational models of molecular networks, growth, and mechanics in a multicellular context. The increased number of

Solidariskt ansvar har under lång tid tillämpats i Svensk lag i fall då flera personer ska svara för ett skadestånd. Det solidariska ansvaret innebär att en skadelidande kan kräva ut hela skadeståndet från endera skadevållaren. För att detta inte ska leda till orimliga slutsatser finns det dock tillfällen vid jämkade skadestånd då det solidariska skadeståndet ej används. I vilka jämkningsfall ett

We develop a new elementary move for simulations of polymer chains in torsion angle space. The method is flexible and easy to implement. Tentative updates are drawn from a (conformation-dependent) Gaussian distribution that favors approximately local deformations of the chain. The degree of bias is controlled by a parameter b. The method is tested on a reduced model protein with 54 amino acids and

Understanding cell-fate decisions in stem cell populations is a major goal of modern biology. Stem and progenitor cell populations are often heterogeneous, which may reflect stem cell subsets that express subtly different properties, including different propensities for lineage selection upon differentiation, yet remain able to interconvert. We discuss these properties with examples both from the

We discuss some aspects of the current status of event generators for small-x DIS. In particular we report on recent results using the CCFM evolution implemented in the SMALLX and CASCADE program concerning the importance of the so-called consistency constraint, and compare with the linked dipole chain model implemented in the LDC program. We point out some potential problems with the resolved vir

We present a general method, the δ-test, which establishes functional dependencies given a sequence of measurements. The approach is based on calculating conditional probabilities from vector component distances. Imposing the requirement of continuity of the underlying function, the obtained values of the conditional probabilities carry information on the embedding dimension and variable dependenc

We deal with some halos generated by the divergent light from a nearby source. After discussing how the divergent light transforms some halo features, we give an outline of a method of handling the simulation of a divergent-light halo. The simulation method is then successfully tested on some well-documented halo observations. We also present a "simulation atlas" that shows halos produced by cryst

Experimental and theoretical studies of lifetimes and transition probabilities for doubly ionized mercury, Hg III, are reported. Such data are currently of great astrophysical interest because observations with the Goddard high resolution spectrograph on board the Hubble space telescope have shown some 5d(9)6s-5d(9)6p transitions of Hg III in the spectrum of the chemically peculiar star chi Lupi.

This invention provides a method for protein structure alignment. More particularly, the present invention provides a method for identification, classification and prediction of protein structures. The present invention involves two key ingredients. First, an energy or cost function formulation of the problem simultaneously in terms of binary (Potts) assignment variables and real-valued atomic coo

We have developed a prognostic index model for survival data based on an ensemble of artificial neural networks that optimizes directly on the concordance index. Approximations of the c-index are avoided with the use of a genetic algorithm, which does not require gradient information. The model is compared with Cox proportional hazards (COX) and three support vector machine (SVM) models by Van Bel

The mean field theory approach to knapsack problems is extended to multiple knapsacks and generalized assignment problems with Potts mean field equations governing the dynamics. Numerical tests against 'state of the art' conventional algorithms shows good performance for the mean field approach. The inherently parallelism of the mean field equations makes them suitable for direct implementations i

In this thesis, a Glauber Monte-Carlo event generator is developed and used to analyze proton-Ion (p -$^{63}$Cu and p -$^{197}$Au) and Ion-Ion ($^{63}$Cu -$^{63}$Cu and $^{197}$Au -$^{197}$Au) collisions. Three different sub-collision models are implemented, the black disk, grey disk and oscillating grey disk models, and their validity is compared. The predicted nucleon-nucleon cross-sections by t

Fåmansbolagsreglerna är ett mycket komplext regelverk som har sedan de första bestämmelserna infördes diskuterats, kritiserats och utvecklats. Bestämmelser som reglerade situationer som kunde uppstå i företag med en eller ett fåtal ägare infördes för första gången år 1976. Bestämmelserna infördes framförallt för att undvika att den fördelning av arbetsinkomster och kapitalinkomster valdes, som var

This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically. Also the workings of space astrome
