A new instruction overlapping technique for improved anti-disassembly and obfuscation of x86 binaries

The problem of correctly recovering assembly instructions from a binary has received much attention and both malware and license validation code often relies on various anti-disassembly techniques in order to complicate analysis. One well-known anti-disassembly technique is to use overlapping code such that the disassembler starts decoding from an incorrect byte, but still recovers valid code. The

Examining the facts

Facts are once again put to work in philosophical enterprises. The discussion in this paper is conducted under the presumption that we for this reason need to examine the nature of facts anew. To some extent it has been taken for granted that the question of properties and particulars is the primary problem to solve, and that the question of facts is secondary. This approach naturally leads to man

Cycle distributions for Gaussian waves - Exact and approximative results

Wave cycle distributions are notoriously difficult to calculate. Available analytic approximations, like those suggested by Longuet-Higgins (1983) and Cavanie, Arhan and Ezraty (1976) make use only of a few spectral moments, and are unreliable for moderate waves. To find distributions under general spectrum shape and parameters one has to use efficient numerical algorithms based on high-dimensiona

PLANT-BACTERIAL AND PLANT-FUNGAL COMPETITION FOR NITROGEN AND PHOSPHORUS

Popular Abstract in Swedish Är det möjligt att det pågår en hård kamp under våra fötter när vi tar en promenad i den Skånska lövskogen? Oftast tänker man på ett positivt förhållande mellan växter och marken's bakterier och svampar, där den autotrofa växten omvandlar luften's kol (C), i form av koldioxid, till organiskt C som därigenom blir tillgängligt för mikroorganismerna. Mikroorganismerna bryCompetition between and within species has been one of the most studied concepts in ecology. In this thesis the aim was to test the idea of plant-microbial competition for N and, by studying this interaction, to gain a better understanding of different N processes in soil. The research carried out seeks to investigate plant-microbial competition for N based on the definition that competition only

Historiedidaktik, politik och demokratisering i Östeuropa

Detta kapitel är en vidareutveckling av några av mina analyser av hur ”politik nerifrån” kan påverka historien och av spelfilmens roll i skapandet av historiemedvetande. De tidigare studierna är “Building Civil Society and Democracy East of Elbe: Problems and Prospects”, i Sven Eliaeson, (ed.) Building Civil Society and Democracy East of Elbe, (utkommer 2006), ”’The past is never dead.’ The Histor

The role of intersubjectivity in intentional communication

The present account explains (i) which elements of the act of nonverbal reference are intersubjective, (ii) which major effects intersubjectivity has on the development of intentional communication and at what stages, and (iii) how intersubjectivity contributes to trigger the general capacity for nonverbal reference in the second year. First, intersubjectivity is analysed in terms of a mutual or i

Precise Orbit Determination for Low Earth Orbit Satellites

The precise orbit determination problem is to accurately determine the position and velocity vectors of an orbiting satellite. In this paper we review the general contents of the orbit determination process, with particular emphasis on Low Earth Orbit (LEO) satellites. The different orbit determination approaches and the different force models contained within are briefly discussed. The two main e

Managing Information Systems Integration in Corporate Mergers and Acquisitions

Corporate mergers and acquisitions (M&As) have during the last decade established themselves as prominent tools for corporate strategy. Consequently, more and more organizations direct their attention towards the potential benefits of a corporate merger and acquisition (M&A) and the problems of leveraging the potentials. This thesis addresses information systems (IS) integration in the con

När anses en bioteknologisk uppfinning vara komplett och praktiskt användbar? - Del II (When does European patent law regard a biotechnological invention as complete and having an industrial application?)

Denna artikel utgör den andra delen av två uppsatser som behandlar det patenträttsliga kravet att en patentsökt teknologi måste vara praktiskt användbar. Fokus ligger på gen- och proteinrelaterade uppfinningar. En tredje uppsats kommer att undersöka kravet på en tillräcklig beskrivning av dessa teknologier. Medan den första delen analyserade den US-amerikanska tolkningen av det särskilda ”utility”

Naphthoxylosides Investigations into glycosaminoglycan biosynthesis

Popular Abstract in Swedish Många av cellernas reglerings-, kommunikations- och interaktionssystem styrs av kolhydrater. Dessa kolhydrater sitter ofta bundna på proteiner och bildar då så kallade makromolekyler. En sådan grupp av makromolekyler kallas för glykosaminoglykaner. I de flesta medlemmar av denna grupp sitter långa kolhydratkedjor fast på proteinet via sockret xylos, även känt som björksGlycosaminoglycans (GAGs) are members of a family of polysaccharide structures consisting mostly of repeating disaccharide units. Most GAGs are attached to specific serine residues in proteins to form proteoglycans (PGs). GAGs and PGs show a large and diverse number of biological functions ranging from cell cycle regulation and control of formation of blood vessels to modification of tissue transp

Acute improvement of contralateral hand function after deafferentation

To study cortical re-organisation after acute hand deafferentation, we investigated 10 experimental subjects and 10 controls for function in the left hand, before, during and after tourniquet induced anaesthesia of the right hand. fMRI was performed in three experimental subjects. Tourniquet-induced right hand anaesthesia resulted in rapid significant improvement in grip strength, tactile discrimi
