Self-supervised learning has become an important approach for machine learning in remote sensing, where large amounts of unlabeled satellite data exist but only lim- ited labeled datasets are available. Contrastive methods such as SimCLR have been adapted to multimodal Sentinel-1 and Sentinel-2 imagery, but current SimCLR-based approaches rely on deterministic embeddings and therefore lack the abi
The dispersion-scan technique (d-scan) is a well-established technique for the measurement of ultrashort laser pulses. While a single-shot version of d-scan is relatively easy to implement for sub-10 fs laser pulses, this becomes increasingly difficult as the pulse duration increases due to the need for a larger dispersion range, which scales quadratically with the Fourier transform limit (FTL). H
Context. The majority of Galactic globular star clusters (GCs) have been reported to contain at least two populations of stars (hereafter, we use P1 for the primordial and P2 for the chemically enriched population). Recent observational studies found that dynamically old GCs have P1 and P2 spatially mixed due to relaxation processes. However, in dynamically young GCs, where P2 is expected to be mo
Insulin resistance (IR) contributes to atherogenic dyslipidemia and elevated ASCVD risk. Apolipoprotein A1 (ApoA1)-associated lipoproteins have diverse anti-atherogenic functions, but it is unclear whether IR drives adverse changes in their proteomic composition. We hypothesized that IR is associated with an atherogenic ApoA1 proteome and that insulin-sensitizing interventions would improve its co
Acoustic forces occurring in resonant microfluidic chambers allow the handling of micrometer-sized particles. Trapping of nanoparticles has been shown for high particle concentrations and after preseeding the chamber with larger particles. We show that the trapping mechanism is due to synergy between hydrodynamic shielding and acoustic forces. Acoustic interactions are significant only when seed p
Atmospheric inverse modelling and ecosystem data assimilation are two complementary approaches to estimate CH4 emissions. The inverse approach infers emission estimates from observed atmospheric CH4 mixing ratio, which provide robust large scale constraints on total methane emissions, but with poor spatial and process resolution. On the other hand, in the ecosystem data assimilation approach, the
Photonic topological insulators and self-induced nonreciprocity based on nonlinear effects in asymmetric structures have garnered increased attention due to their potential applications in quantum information technologies and advanced photonic integrated circuits. In this study, we combine these two fields and present asymmetric photonic crystal designs based on all-dielectric checkerboard structu
The striped p × √3 reconstruction of Au(111) is a textbook example of how electrode surfaces reorganise in response to an applied potential. Using in situ high-energy surface X-ray diffraction, we track the surface reconstruction in 0.1 M HClO4electrolyte while the potential is cycled at both 5 mV s−1and 2 mV s−1between 0.06 V and 0.86 V versus RHE. Reciprocal-space maps, collected every ∼10 s, sh
Non-round cell sarcomas may occur in children or young adolescents. We present some examples of the most common entities: epithelioid sarcoma, osteosarcoma; malignant peripheral nerve sheath tumor (MPNST), congenital infantile fibrosarcoma, and synovial sarcoma.
BACKGROUND AND OBJECTIVE: The treatment landscape for metastatic hormone-sensitive prostate cancer (mHSPC) is evolving rapidly. Real-world data (RWD) are essential to understand actual treatment use and outcomes. This study aimed to describe treatment trajectories and clinical outcomes in a large, multicenter RWD cohort under the PIONEER project. METHODS: Eight European and US databases (2016-2020
BACKGROUND AND OBJECTIVE: A post hoc analysis of TITAN evaluated the clinical benefit of apalutamide plus androgen-deprivation therapy (ADT) versus ADT alone in metastatic hormone-sensitive prostate cancer (mHSPC) with high disease burden. METHODS: Patients were assessed in subgroups of those with four to fewer than ten, ten to <20, or ≥20 bone metastases; with lung but not liver metastases; and w
An approach to reducing greenhouse gas emissions that shows promise is the electrochemical conversion of CO2 to products with added value. Here, we present [Co(8HQ-Tpy)(H2O)]2 (PF6)2 ([Co1]), a cobalt-based molecular electrocatalyst that can convert CO2 to CO in a DMF/H2 O mixture (4.8 : 0.2 v/v) in a selective manner (8HQ-Tpy = 2-([2,2′:6′,2′′-terpyridin]-4′-yl)quinolin-8-ol). At an overpotential
This is the Replicated Computational Results (RCR) Report for the article ‘Stress Testing Control Loops in Cyber-Physical Systems’. The article proposes a novel approach for testing Cyber-Physical Systems (CPS) based on the integration of the guarantees that can be provided with the control theoretical models into the software testing practices. This RCR report describes how to reproduce the empir
AIM: We aimed to investigate if the incidence of type 1 diabetes increased in children during the SARS-CoV-2 pandemic and whether SARS-CoV-2 antibodies were more frequently present at diagnosis compared with healthy individuals. We also examined whether clinical characteristics and coexisting autoimmunity differed between SARS-CoV-2 antibody positive and negative individuals.METHODS: This retrospe
Spill och dolda kostnader äter upp enorma resurser i industrin. Genom att anpassa Toyotas berömda Lean-metoder för plastfilmstillverkning hittar detta arbete verktygen för att avslöja de dolda kostnaderna och minska slöseriet. Föreställ dig ett isberg. Ovanför vattenytan syns toppen, de uppenbara kostnaderna där material slängs, eller när en maskin går sönder och måste repareras. Men under ytan This master thesis investigates the feasibility of utilizing Lean Manufacturing Principles, derived from traditional discrete manufacturing to enhance efficiency and reduce waste within a continuous process industry environment at Graphic Packaging Flexibles (GPI) in Lund. The company produces fiber- and plastic-based packaging solutions and faces challenges regarding waste. The purpose of this st

The main focus of the project has been to find a new method for tightening a GPHE that is more accurate than the current method. This is achieved by factoring in manufacturing tolerances of the ingoing parts. Other factors such as the number of channel plates, channel plate ma
Uppsatsen behandlar hur Rysslands president Vladimir Putin legitimerar in-vasionen av Ukraina genom historiska narrativ i kontrast till non-interventionsprincipen. Med utgångspunkt i ett rättshistorisk perspektiv utförs en diskurshistorisk analys tillsammans med historiedidaktisk ansats för att undersöka hur dessa argument förhåller sig till non-interventionsprincipen. Analysen grundar sig på fyraThe thesis examines how the President of the Russian Federation, Vladimir Putin, seeks to legitimize the invasion of Ukraine through historical narratives and legal arguments. By applying a legal-historical approach combined with discourse-historical analysis, the study investigates how these narratives and arguments relate to the principle of non-intervention in international law. The analysis is
Aktierelaterade incitamentsprogram är mycket vanligt förekommande bland svenska bolag och kan användas för att attrahera, motivera och behålla anställda och nyckelpersoner. Programmen innebär att deltagaren tilldelas en villkorad rätt till ersättning som är knuten till aktier, aktiekursen eller andra finansiella instrument utgivna av arbetsgivarbolaget eller dess koncern. Civilrättsligt kan prograStock incentive plans are commonly used by Swedish companies to attract, motivate, and retain employees and executives. Under such plans, participants are granted a conditional right to compensation related to shares, share prices, or other financial instruments issued by the employer company or entities within its group. These plans are generally divided into contractual plans and dilution-based
How Do We Treat the Super-Elderly with Distal Radius Fractures and What is the Outcome? A Register Study in 239 Patients of 80 years or olderLinnea Sara Arvidsson, MD; Ellen Lööf, Bachelor of Medicine; Antonio Abramo, PhD; Magnus Tägil, PhDLund University, Lund, SwedenIntroductionWith a rapidly ageing population, the number of wrist fractures will rise dramatically in the super elderly group. BasiIntroductionWith a rapidly ageing population, the number of wrist fractures will rise dramatically in the super elderly group. Basic knowledge of outcome after fracture in this heterogenic group is absent. Our aim was to use our prospective distal radius fracture register to study the super-elderly patients with distal radius fractures. We hypothesized that the health status of the patient, rather
