När man talar om framtiden finns det ett begrepp som dyker upp i nästan varje diskussion: "articiell intelligens". Vår fascination kring framtidens potentiellt självtänkande robotar speglas i hur mycket det diskuteras i alla yrkesgrupper just nu, oavsett om ämnet är koldioxidutsläpp, självkörande bilar eller automatiska inköpslistor. Men hur långt har egentligen maskininlärning kommit id
Som de flesta av oss vet så kretsar planeter i elliptiska banor runt stjärnor. Vissa planeter som ligger väldigt nära de stjärnor som de kretsar får uppleva visa effekter som inte märkbart påverkar de planeterna i omloppsbana längre bort. Dessa effekter uppkommer ur så kallade tidvattenskrafter som härstammar från det faktum att gravitationskrafter beror väldigt mycket på avstånd mellan objekt. DePlanets that orbit their host star closely experience tidal forces due to the strength of gravity not being uniform all over the planet. This leads to effects such as tidal spin synchronization, tidal eccentricity damping and tidal semi-major axis damping. This project aims to study how the time scales for these phenomena are affected by the planetary parameters such as mass, radius and the tidal
BACKGROUND: The value of CT at the time of diagnosis for patients with cutaneous head and neck melanoma clinically asymptomatic for metastatic disease is unclear. METHODS: A retrospective medical chart review was performed on 198 consecutive patients identified with primary T1b-T4b head and neck melanoma clinically asymptomatic for metastatic disease referred for sentinel lymph node biopsy proceduBACKGROUND: The value of CT at the time of diagnosis for patients with cutaneous head and neck melanoma clinically asymptomatic for metastatic disease is unclear.METHODS: A retrospective medical chart review was performed on 198 consecutive patients identified with primary T1b-T4b head and neck melanoma clinically asymptomatic for metastatic disease referred for sentinel lymph node biopsy procedur
Laser Shock Peening (LSP) and conventional Shot Peening (SP) are processes that aim to improve the surface properties of a workpiece by inducing compressive residual stresses. The peening processes also cause martensitic phase transformation in austenitic steels. Interestingly, experimental studies report significant differences in martensite content depending on the used peening process.

A directional crack growth criterion in a compressed elastic perfectly plastic material is considered. The conditions at the crack-tip are evaluated for a straight stationary crack with a small incipient kink. Remote load is a combined hydrostatic pressure and pure shear applied via a boundary layer. Crack surfaces in contact are assumed to develop homogenous Coulomb friction.

What is the role of gender in Eastern Christianity? In this volume, Orthodox experts of different disciplines and cultural backgrounds tackle this complex question. They engage critically with gender issues within their own tradition. Rather than simply accepting pervasive assumptions and practices, the authors challenge readers to reconsider historically or theologically justified views by offeriWhat is the role of gender in Eastern Christianity?

Galaxer formas när enorma gasmoln kollapsar på grund av gravitation. Små ojämnheter får gasen att rotera vilket leder till att molnet pressas ihop till en disk. Stjärnor bildas av gasen som i sin tur fortsätter att rotera. Under tid dör stjärnorna och blir till gas igen som sedan bildar nya stjärnor. Interaktioner mellan galaxersker genom kollisioner och gravitationskrafter. Det kan påverka galaxThe Large and Small Magellanic Clouds (LMC & SMC) are the two largest galaxies orbiting the Milky Way (MW). The interactions between them have affected the evolution of both galaxies. The interactions have affected the galaxies differently depending on how strong they have been. Tidal forces from the interactions are argued to have produced a stream of stars and gas called the Magellanic Bridg
3 mars 2026 11:30 till 17:30 | Seminarium The LUDC Diabetes Research Day is a yearly event with the aim of increasing the knowledge of diabetes research. Junior and senior diabetes researchers give lectures on current research during the day. Talks are also given by the winners of the Leif C. Groop Award for Outstanding Diabetes Research, the Leif C.

Genom att observera och intervjua invånarna i Lund, kan man erhålla mycket information om historien och infrastrukturen för staden. Detta tyder på en särskilt självklar princip; om man studerar de mindre beståndsdelarna av ett system, så kan man erhålla egenskaper som är gällande för systemet i helhet. Detta är precis vad dagens astronomer utnyttjar för att lära sig mera om vårt universum. De minsThe first part of this thesis deals with the dynamical estimation of the Oort constants using proper motions and parallaxes provided from the Gaia-DR1 TGAS catalogue. The photometric information was provided by the 2MASS catalogue. The Oort constants calculated from the TGAS catalogue are compared to those obtained from the original Hipparcos catalogue in order to attempt to estimate how well Gaia
Varför gör vissa bakterier oss sjuka men inte andra? Hur kommer det sig att vissa bakterier lyckas överleva och infektera särskilda delar av kroppen men väldigt sällan andra? Bakterier och människor har evolverat länge tillsammans och har därmed lyckats utveckla specifika angrepps och försvarsmekanismer mot varandra. Det är känt sedan tidigare att några bakterier uttrycker proteiner med förmågan Bacteria and humans have co-evolved since their common existence. They have thereby developed very specific defence and target mechanisms against one another. Understanding the complex biomolecular processes behind these interactions can be of great use for developing treatments against bacterial diseases. The aim of this thesis project was to verify, and introduce a model for understanding, the i
När vi letar efter exoplaneter finns det ett antal olika metoder för att hitta dem. Den mest framgångsrika är transitmetoden där ljusstyrkan hos en stjärna studeras under en längre tid. När en planet passerar mellan sin stjärna och en observatör kan en minsking i stjärnans ljusstyrka ses. Uppreras detta i regelbunda intervall kan slutsatsen att det finns en planet runt stjärnan dras. Genom att stuA transit is a phenomenon where a planet passes between its host star and an observer blocking out part of the light from the star. This decrease can be measured and used to gain information about the planet. The Kepler and TESS telescopes are examples of space telescopes using the transit method to detect exoplanets. For systems with more than one planet around the same star variations between th
