Proton exchange between titratable amino acid residues and the surrounding solution gives rise to exciting electric processes in proteins. We present a proton titration scheme for studying acid-base equilibria in Metropolis Monte Carlo simulations where salt is treated at the Debye-Huckel level. The method, rooted in the Kirkwood model of impenetrable spheres, is applied on the three milk proteins
A simple method is described for a rough classification of soil bacterial populations. The method makes use of a commercially available biochemical test system and the test results are analysed in a multivariate classification program on a microcomputer. The method was used for classification of bacteria from rape rhizosphere.
We present a fast algorithm for optimal alignment between two similar ordered trees with node labels. Let S and T be two such trees with S and T nodes, respectively. If there exists an optimal alignment between S and T which uses at most d blank symbols and d is known in advance, it can be constructed in O(n log n (.) (maxdeg)(3) (.) d(2)) time, where n = max{S, T} and maxdeg is the maximum degree
A new simple algorithm for fast correlation attacks on stream ciphers is presented. The advantages of the new approach are at least two. Firstly, the new algorithm significantly reduces the memory requirements compared with some recent proposals [2],[3]. This allows more powerful attacks than previously. Secondly, the simplicity of the algorithm allows us to derive theoretical results. We determin
Fast egendom, i dagligt tal mark, representerar stora sociala och ekonomiska värden för dess innehavare. Samtidigt har samhället i form av stat och kommun alltid haft ett intresse av att kunna ta privat mark i anspråk för gemensamma anläggningar som vägar, el- och telefonledningar och olika former av skyddade områden. För detta betalar samhället ut ersättningar till de berörda fastighetsägarna. Ri
PURPOSE: Interventional radiology techniques cause radiation exposure both to patient and personnel. The radiation dose to the operator is usually measured with dosimeters located at specific points above or below the lead aprons. The aim of this study is to develop and validate two fast Monte Carlo (MC) codes for radiation transport in order to improve the assessment of individual doses in interv
We present the interface between MadGraph5-aMC@NLO, a self-contained program that calculates cross sections up to next-to-leading order accuracy in an automated manner, and APPLgrid, a code that parametrises such cross sections in the form of look-up tables which can be used for the fast computations needed in the context of PDF fits. The main characteristic of this interface, which we dub aMCfast
Popular Abstract in Swedish I denna avhandling behandlas två delvis överlappande teman; inversa problem av tomografisk karaktär samt snabba och noggranna metoder för applicering av faltningsoperatorer. Inom det första temat så studeras det inversa problemet inom Dopplertomografi och för detta ändamål så introduceras Dopplermomenttransformen. Genom att undersöka egenskaperna hos denna transform såThere are two, partially interlaced, themes treated in this thesis; inverse problems of tomographic type and fast and accurate methods for the application of convolution operators. Regarding the first theme, the inverse problem of Doppler tomography is considered and the Doppler moment transform is introduced for that purpose. By investigating the properties of the transform, we prove results reg
New rate-compatible convolutional (RCC) codes with high constraint lengths and a wide range of code rates are presented. These new codes originate from rate 1/4 optimum distance spectrum (ODS) convolutional parent encoders with constraint lengths 7-10. Low rate encoders (rates 115 down to 1/10) are found by a nested search, and high rate encoders (rates above 1/4) are found by rate-compatible punc
We regard the classic Thue–Morse diffraction measure as an equilibrium measure for a potential function with a logarithmic singularity over the doubling map. Our focus is on unusually fast scaling of the Birkhoff sums (superlinear) and of the local measure decay (superpolynomial). For several scaling functions, we show that points with this behavior are abundant in the sense of full Hausdorff dime
Ground source heat pump systems, operating in conjunction with vertical ground heat exchangers, will play a key role in decarbonising heating and cooling of buildings. Design of traditional borehole heat exchangers relies on tools which implement routine analytical relationships between heat transferred and the temperature change in the ground and circulating thermal fluid. However, for novel pile
The need for large-scale production of highly accurate simulated event samples for the extensive physics programme of the ATLAS experiment at the Large Hadron Collider motivates the development of new simulation techniques. Building on the recent success of deep learning algorithms, variational autoencoders and generative adversarial networks are investigated for modelling the response of the cent
Lines and points are complementary local features, whose combination has proven effective for applications such as SLAM and Structure-from-Motion. The backbone of these pipelines are the local feature matchers, establishing correspondences across images. Traditionally, point and line matching have been treated as independent tasks. Recently, GlueStick proposed a GNN-based network that simultane-ou
Many surveillance applications could benefit from the use of stereo cam- eras for depth perception. While state-of-the-art methods provide high quality scene depth information, many of the methods are very time consuming and not suitable for real-time usage in limited embedded systems. This study was conducted to examine stereo correlation methods to find a suitable algorithm for real-time or near
The observed imbalance of matter and antimatter in the universe cannot be fully explained by the Standard Model of particle physics. One proposed mechanism to account for this discrepancy is the violation of baryon number B, a process that has yet to be experimentally observed. The HIBEAM/NNBAR project, a proposed two-stage experiment at the European Spallation Source, aims to find evidence of bar
