We establish an exactly tight relation between reversible pebblings of graphs and Nullstellensatz refutations of pebbling formulas, showing that a graph G can be reversibly pebbled in time t and space s if and only if there is a Nullstellensatz refutation of the pebbling formula over G in size t + 1 and degree s (independently of the field in which the Nullstellensatz refutation is made). We use t
OBJECTIVE: Fine-needle aspiration cytology (FNAC) from bone lesions has been proven to be a useful diagnostic tool but lacks standardisation. The aim of the study was to evaluate the diagnostic utility of FNAC as a basis to propose and test a reporting system for bone reporting cytopathology.METHODS: This retrospective study is based on patients with bone lesions, that were approached by cytology
The ways in which we experience life through, with and around media constitutes creative practices in our daily routines. However, media use is in part associated with harmful effects, for example television viewing amongst children and young people (Livingstone 2009). Discourses around digital games have been echoing the same type of concerns, becoming one of the focal points of these struggles i
In this article, we analyze the nexus between political regimes and external voting rights. Using a global longitudinal dataset, we report that higher levels of inclusion and contestation bring higher probabilities that a state adopts and implements emigrant enfranchisement. Taking outliers from our quantitative assessment, we then further examine two liberal democracies, Ireland and Uruguay, and
En del av publiceringskostnaden betalas av LU centralt och därefter fördelas resten av kostnaden ut på fakulteterna baserat på storleken på forskningsintäkterna. Fakulteten fakturerar i sin tur sedan den publicerande forskaren denna del av kostnaden för publikationen. Detsamma gäller om man publicerar i rena open access-tidskrifter som inte ingår i något av förlagsavtalen.På Medicinska fakulteten

Mixed phase (rutile/anatase)TiO2 nanorods have been synthesized using an anionic surfactant template. Nanorod synthesis has been achieved using mild reaction conditions and without using any rod-shaped template. The shape and crystallinity of the TiO2 nanomaterials can be modulated by careful control of the surfactant concentration. The novelty of the present work is that the anatase/rutile mixed
In the present work non-idealities of flat burner-stabilized flames at atmospheric and low pressures are examined using PIV measurements, which are supported by and analyzed with the help of CFD modeling. Radial and axial velocity profiles measured in the cold flow and in the flames at atmospheric and at lower pressures are presented. Two possible reasons for the drop in the apparent laminar burni
Specific alterations (mutations, deletions, insertions) of virus genomes are crucial for the functional characterization of their regulatory elements and their expression products, as well as a prerequisite for the creation of attenuated viruses that could serve as vaccine candidates. Virus genome tailoring can be performed either by using traditionally cloned genomes as starting materials, follow
Publicerat 20 mars 2005 En tickande hälsobomb Av Richard Åkesson Vår bästa tid är nu. Ja, så är det troligen. Förmodligen upplever vi kulmen på motionsvågen för tillfället. Framtida äldregenerationer kommer att ha helt andra, och sämre vanor. MALMÖ. - Vi har sett en förbättring av hälsan i Sverige i många år bland 80- och 90-åringarna, men nu kommer alltmer motstridiga signaler. Jag är synnerligen

Avtalsbundenhet uppstår genom likalydande viljeförklaringar. När en part har givit ett anbud och en annan part en accept, har ett avtal kommit till stånd. Anbudet ska vara bindande och accepten ska vara ren och lämnas inom acceptfristen. Är så inte fallet kan det vara fråga om en sådan situation som genererar svarsplikt. Svarsplikt innebär att en part måste uppmärksamma sin motpart på att ett missBinding contracts arise from identical declarations of intent. When one party has made an offer and another party has made an acceptance, a contract has been formed. The offer must be binding and the acceptance must be qualified and submitted within the stipulated period for acceptance. If this is not the case, it may be a situation that generates a duty to reply. The duty to reply means that a pa
During the Swedish NATO negotiations, the Turkish president Recep Tayyip Erdoğan once again raised the question of whether Türkiye could be welcomed into the EU. This thesis examines Türkiye’s shortcomings concerning their EU accession, focusing on the human rights of Kurdish people by answering the research questions: what is the state of human rights of the Kurd-ish people in Türkiye, and what c

Background: Widespread implementation of Alzheimer's disease biomarkers in routine clinical practice requires the establishment of standard operating procedures for pre-analytical handling of cerebrospinal fluid (CSF). Methods: Here, CSF collection and storage protocols were optimized for measurements of β-amyloid (Aβ). We investigated the effects of (1) storage temperature, (2) storage time, (3)
In scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the classical as well as the quantum domain. In this paper, we study an implementation of Maxwell's demon that can operate in both domains. In particular, we investigate information-to-work conversion over the quantum-to-classica
Introduction: Falls among hospitalized older adults increase morbidity, prolong hospital stays, and raise healthcare costs. Sensor-based technologies and medical devices are emerging tools for fall prevention, but their clinical effectiveness remains uncertain. This systematic review aimed to assess their effectiveness in reducing inpatient falls, staff workload, and physical restraint use in hosp
