In this paper, we develop an uncertainty-aware decision-making and motion-planning method for an autonomous ego vehicle in forced merging scenarios, considering the motion uncertainty of surrounding vehicles. The method dynamically captures the uncertainty of surrounding vehicles by online estimation of their acceleration bounds, enabling a reactive but rapid understanding of the uncertainty chara
Nils Månsson Mandelgren och kampen för kulturens framtid är en antologi med syftet att ge nya perspektiv på Mandelgrens omfattande livsverk. Hittills har forskningen frmäst haft fokus på hans dokumentation av äldre kulturyttringar, men hans stridbarhet och oräddhet i att utmana etablissemanget hade sikte på hur samtidens och framtidens kulturinstitutioner borde utformas och organiseras. I boken di
Renin from plasma, kidney, and recombinant sources was previously demonstrated to cleave C3 to C3a and C3b. C3a was generated at a similar rate to that by C3 convertase, and C3 cleavage was inhibited by the renin inhibitor aliskiren. Renin endogenously produced by Calu6 cells also led to C3 deposition on cells. These results have been challenged by another group suggesting that recombinant renin d

BACKGROUND: The advent of PD-1/PD-L1 inhibitors has revolutionized lung cancer treatment, necessitating accurate PD-L1 immunohistochemical (IHC) assessment. While standardized for formalin-fixed paraffin-embedded (FFPE) histological samples, PD-L1 testing on cytology remains challenging. This review aims to address the complexities of PD-L1 IHC in cytology, focusing on validation guidelines, quali
Svensk Kolinlagring och Lunds universitet (LUCSUS) samlade 19 personer för en workshop på Torsåker gård i syfte att diskutera styrmedel och strategier för att öka kolinlagringen i jordbruksmark, och hur dessa verktyg skulle kunna utformas för att stödja en omställning till ett socialt och ekologiskt hållbart matsystem. Deltagarna representerade olika delar och nivåer av matsystemet och bidrog med
Årligen upptäcks nya kärlväxter i Sverige. Det kan vara arter som etablerar sig i Sverige i klimatförändringarnas spår, som följer med internationella transporter, och inte minst trädgårdsrymlingar. Det finns flera skäl till att dokumentera dessa, inte minst för att förebygga spridning av invasiva arter. Biologiska museet i Lund tar emot belägg och listar här de arter som var nya för Sverige 2023.
We study an information design problem to reduce congestion in transportation networks. In presence of an uncertain network state, the central planner may sends private signals to the users, with the goal of steering the user equilibrium towards the system optimum flow. We consider private signals and provide sufficient conditions under which optimality may be achieved by information provision in
This is the first of three chapters (this chapter and Chapters 7 and 8) on diffusion MRI acquisition for tractography. For tractography, the acquisition is optimized for the estimation of fiber orientation. This chapter covers the creation of diffusion contrast. This is largely independent of the image encoding part of the MRI sequence, which is covered in Chapter 7. Unless explicitly stated, this
This is the second of three chapters on diffusion MRI acquisition for tractography. This chapter covers image formation, which is largely independent of the creation of diffusion contrast (Chapter 6). The Stejskal-Tanner diffusion experiments in the 1960s were bulk NMR measurements of diffusion; the addition of spatial localization, i.e., imaging, would follow decades later. The excitation and rea
To effectively navigate out of the climate crisis, a new interdisciplinary approach is needed to guide and facilitate research that integrates diverse understandings of how transitions evolve in intertwined social–environmental systems. The concept of tipping points, frequently used in the natural sciences and increasingly in the social sciences, can help elucidate processes underlying major socia
Aquaglyceroporins are channels that facilitate the flux of glycerol and water across lipid bilayers. Although structural information is available for several aquaglyceroporins, the details of how water and glycerol selectivity are maintained and how protons are excluded remain elusive. An approach to obtaining data on the hydrogen atom positions is to apply neutron macromolecular crystallography.
We study the Pauli operator in a 2-dimensional, connected domain with Neumann or Robin boundary condition. We prove a sharp lower bound on the number of negative eigenvalues reminiscent of the Aharonov-Casher formula. We apply this lower bound to obtain a new formula on the number of eigenvalues of the magnetic Neumann Laplacian in the semiclassical limit. Our approach relies on reduction to a bou
This study explores a collaborative project between various levels of public administration in southern Sweden, designed to encourage companies to adopt sustainable transportation practices. Conducted with the participation of researchers from Lund University, the project supports companies in developing and annually revising action plans that include specific sustainability goals, assigned respon
In this paper, we present a summary of fractal calculus and propose the use of Lagrange multipliers for both fractal calculus and fractal variational calculus with constraints. We examine the application of these methods across various branches of physics. By employing fractal variational calculus with constraints, we derive fundamental equations such as the fractal mechanical wave equation, the f
Avoiding severe global warming requires large-scale removals of atmospheric carbon dioxide. Forest regeneration offers cost-effective carbon removals, but annual rates vary substantially by location and forest age. Here we generate grid-level (~1-km2) growth curves for aboveground live carbon in naturally regrowing forests by combining 109,708 field estimates with 66 environmental covariates. Acro
