Folklore in complexity theory suspects that circuit lower bounds against NC1 or P/poly, currently out of reach, are a necessary step towards proving strong proof complexity lower bounds for systems like Frege or Extended Frege. Establishing such a connection formally, however, is already daunting, as it would imply the breakthrough separation NEXP ⊈ P/poly, as recently observed by Pich and Santhan

The methanol-to-hydrocarbons (MTH) process involves the conversion of methanol, a C1 feedstock that can be produced from green sources, into hydrocarbons using shape-selective microporous acidic catalysts – zeolite and zeotypes. This reaction yields a complex mixture of species, some of which are highly reactive and/or present in several isomeric forms, posing significant challenges for effluent a

Advancements in treatments have significantly improved the prognosis for mantle cell lymphoma (MCL), and there is a growing population of survivors with an increased susceptibility to infections. We assessed the incidence of infections by clinical characteristics and treatment both before and after MCL diagnosis in Sweden. Patients with a diagnosis of MCL ≥ 18 years between 2007 and 2019 were incl

A search for flavour-changing neutral interactions involving the top quark, the Higgs boson and an up-type quark q (q = c, u) is presented. The proton-proton collision data set used, with an integrated luminosity of 139 fb−1, was collected at (Formula presented.) TeV by the ATLAS experiment at the Large Hadron Collider. Both the decay process t → qH in tt¯ production and the production process pp

In the context of global warming, escalating water cycles have led to a surge in drought frequency and severity. Yet, multidecadal fluctuations in drought and their multifaceted influencing factors remain inadequately understood. This study examined the multide-cadal changes in drought characteristics (frequency, duration, and severity) and their geographical focal points within China’s north-sout

We couple to group field theory (GFT) a scalar field that encodes the entanglement between manifold sites. The scalar field provides a relational clock that enables the derivation of the Hamiltonian of the system from the GFT action. Inspecting the Hamiltonian, we show that a theory of emergent gravity arises, and that this can be recast according to the Ashtekar’s formulation of general relativit

The production of dark matter in association with Higgs bosons is predicted in several extensions of the Standard Model. An exploration of such scenarios is presented, considering final states with missing transverse momentum and b-tagged jets consistent with a Higgs boson. The analysis uses proton-proton collision data at a centre-of-mass energy of 13 TeV recorded by the ATLAS experiment at the L

Generation Z (Gen Z) is believed to be more socially and environmentally committed. While environmentally responsible behaviour is crucial to the success of sustainable tourism, little is known about Gen Z's specific environmental behaviours in tourism settings. In this research, the roles of Gen Z's consumption emotions and environmentally friendly behaviour were explored based on cognitive appra

As a part of the LTH Docent Course Spring 2024, this group project interviewed both co-supervisors and doctoral students to understand the roles of co-supervisors in doctoral studies. The study revealed significant variation in co-supervisors' roles across different projects, as confirmed by both students and co-supervisors. The research focused on co-supervisors' activities and levels of engageme

A system has been developed to convert manual wheelchairs into electric wheelchairs, providing assistance to users through the implemented algorithm, which ensures safe driving and obstacle avoidance. While manual wheelchairs are typically controlled indoors based on user preferences, they do not guarantee safe driving in areas outside the user’s field of vision. The proposed model utilizes the dy

Uridine residues present at the wobble position of eukaryotic cytosolic tRNAs often carry a 5-carbamoylmethyl (ncm5), 5-methoxycarbonylmethyl (mcm5), or 5-methoxycarbonylhydroxymethyl (mchm5) side-chain. The presence of these side-chains allows proper pairing with cognate codons and they are particularly important in tRNA species where the U34 residue is also modified with a 2-thio (s2) group. The

A deep understanding of double-directional wireless channels is imperative for wireless system design. This necessitates the development of precise channel models through channel sounding. Given the dynamic nature of wireless channels, a short measurement time is highly desirable. In this paper, we present and validate a dual-polarized millimeter-wave channel sounder that uses a rotating mirror me

This chapter analyses the Spanish Habsburg crypt at the Escorial and the dynamics that caused it to become increasingly inclusive. Two main dynamics are identif ied: family heads exercising increased authority in mandating burials in the Escorial, including for individuals who had indicated other wishes, like siblings and adult children. And peripheral relatives who previously would not have expec

Publikationen sammanställer kunskap relevant för att utveckla och praktisera ledarskap i aktörsgemensamma sammanhang. Innehållet täcker centrala begrepp och beskriver olika organisatoriska miljöer som blir aktuella i samband med kriser och totalförsvar.

This article investigates the dependence on standard contracts in Swedish construction law, particularly AB 04 and ABT 06, due to a lack of specialized laws. Comparing them to similar contracts from other Nordic countries demonstrates the value of cross-border legal understanding. A 2018 Swedish Supreme Court judgment highlights this technique, implying that comparative analysis might improve lega
