Properties of the Grain-128AEAD key re-introduction, as part of the cipher initialization, are analyzed and discussed. We consider and analyze several possible alternatives for key re-introduction and identify weaknesses, or potential weaknesses, in them. Our results show that it seems favorable to separate the state initialization, the key re-introduction, and the A/R register initialization into

Introduction: Tension band wiring of olecranon fractures has high reported rates of complications and reoperations. We aimed to compare classic tension band wiring to cerclage fixation without K-wires in the treatment of displaced olecranon fractures in elderly patients. The primary outcome was reoperation. Secondary outcomes included complications and patient reported outcomes. Outcomes following

Weaknesses in the Grain-128AEAD key re-introduction, as part of thecipher initialization, are analyzed and discussed. We consider and analyzeseveral possible alternatives for key re-introduction and identify weaknesses, or potential weaknesses, in them. Our results show that it seemsfavorable to separate the state initialization, the key re-introduction, andthe A/R register initialization into thr

We study a non-autonomous differential equation describing the one-dimensional motion of a particle interacting with a charged source at the origin. The charge of the source is piece-wise constant; it alternates between two different values, one being positive and the other being negative. We show that the alternation of the charge enriches the behaviour of the system, exhibiting qualitatively new

Background: There is a lack of studies of amyotrophic lateral sclerosis (ALS) in immigrants. Objective: The objective is to study the association between country of birth and incident ALS in first-generation immigrants versus Swedish-born individuals, and in second-generation immigrants versus native Swedes. Methods: Study populations included all adults aged 18 years and older in Sweden, in the f

Purpose: Irritant contact dermatitis (ICD) is a major cause of occupational disease. The aim was to review the relation between exposure to occupational irritants and ICD and the prognosis of ICD. Methods: Through a systematic search, 1516 titles were identified, and 48 studies were included in the systematic review. Results: We found that the evidence for an association between ICD and occupation

Background: Compression of the greater occipital nerve (GON) may contribute to chronic headache, neck pain, and migraine in a subset of patients. We aimed to evaluate whether GON decompression could reduce pain and improve quality of life in patients with occipital neuralgia and chronic headache and neck pain. Methods: In this retrospective cohort study, selected patients with neck pain and headac

Motivated by the influence of deformation-induced microcracks on the effective electrical properties at the macroscale, an electro-mechanically coupled computational multiscale formulation for electrical conductors is proposed. The formulation accounts for finite deformation processes and is a direct extension of the fundamental theoretical developments presented by Kaiser and Menzel (Arch Appl Me

The concept of optic flow, a global pattern of visual motion that is both caused by and signals self-motion, is canonically ascribed to James Gibson's 1950 book "The Perception of the Visual World." There have, however, been several other developments of this concept, chiefly by Gwilym Grindley and Edward Calvert. Based on rarely referenced scientific literature and archival research, this article

När elsparkcyklar ersätter resor med till exempel bil och taxi bidrar de till att minska utsläppen och miljöpåverkan blir mindre. Om elsparkcyklarna däremot ersätter promenader eller resor med cykel och kollektivtrafik blir miljöpåverkan istället större.

As biological surfactants, bile salts (BSs), play important roles in biological processes, i.e., food digestion, but also in BS-related diseases, as well as in applications. In this thesis, the main focus was to gain a fundamental understanding of the intermolecular interactions between BSs and cationic block copolymers with the purpose of developing new BS sequestrants that are used in the treatm

Objective: The purpose of the study was to examine associations between self-esteem and symptoms of anxiety and depression among young adults who lost a parent to cancer. Methods: Older adolescents and young adults, aged 16 to 28 years, who had lost their parent to cancer and had accepted an invitation to join a support group, completed a questionnaire 5 to 8 months after the loss and a similar qu

In this article, we study microscopic properties of a two-dimensional Coulomb gas ensemble near a conical singularity arising from insertion of a point charge in the bulk of the droplet. In the determinantal case, we characterize all rotationally symmetric scaling limits (“Mittag-Leffler fields”) and obtain universality of them when the underlying potential is algebraic. Applications include a cen

Peirce's best idea, and the one least implemented by himself and his followers, is that of an ethics of terminology. Using this ethics as a tool, we suggest that many Peircean terms are in fact misleading, or, as he said himself at the end of his life, "injurious."From the point of view of cognitive semiotics, there is no reason to abide by Peirce's definition of semiosis, but, taking up the two q
