HIP 41378 observed by CHEOPS: Where is planet d?

HIP 41378 d is a long-period planet that has only been observed to transit twice, three years apart, with K2. According to stability considerations and a partial detection of the Rossiter- McLaughlin effect, Pd = 278.36 d has been determined to be the most likely orbital period. We targeted HIP 41378 d with CHEOPS at the predicted transit timing based on Pd = 278.36 d, but the observations show no

Characterisation of the TOI-421 planetary system using CHEOPS, TESS, and archival radial velocity data

Context. The TOI-421 planetary system contains two sub-Neptune-type planets (Pb ~ 5.2 days, Teqb ~ 900 K, and Pc ~ 16.1 days, Teq,c ~ 650 K) and is a prime target to study the formation and evolution of planets and their atmospheres. The inner planet is especially interesting as the existence of a hydrogen-dominated atmosphere at its orbital separation cannot be explained by current formation mode

Observation of ᴧb0→ ᴧc+(*)0K and ᴧb0→ ᴧc+ Ds*− decays

The decays Λb0→Λc +D¯(∗)0K- and Λb0→Λc+Ds∗- are observed for the first time, in proton-proton collision data at s=13TeV, corresponding to an integrated luminosity of 5.4fb-1 collected with the LHCb detector. Their ratios of branching fractions with respect to the Λb 0→Λc +Ds - mode are measured to be (Formula presented.) where the first uncertainties are statistical, the second systematic, and the

Groupexhibition. Philip Dufva, Maria Hedlund och Eva Löfdahl.6 juli 2024–6 oktober 2024Jag betraktar allt som passerar mina ögon och testar det mot ett behov”.Citatet ovan, liksom utställningens titel, är hämtat från Eva Löfdahl – en konstnär som arbetar i många olika material och tekniker, alltid med det specifika behovet hos detta speciella verk som utgångspunkt – snarare än en färdig idé, ett u

Effect of Psychotherapy on Intolerance of Uncertainty : A Systematic Review and Meta-Analysis

Intolerance of uncertainty (IU) is the tendency to react negatively on affective, cognitive and behavioural levels to uncertain situations and to harbour negative beliefs about the implications of uncertainty. IU has been linked to psychopathology and shown to impact treatment outcomes. This study systematically reviewed the literature and performed a meta-analysis of the effects of psychotherapy

From Proof Complexity to Circuit Complexity via Interactive Protocols

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

PEPICO analysis of catalytic reactor effluents towards quantitative isomer discrimination : DME conversion over a ZSM-5 zeolite

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

Infections in patients with mantle cell lymphoma

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

Search for flavour-changing neutral tqH interactions with H → γγ in pp collisions at (Formula presented.) TeV using the ATLAS detector

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

Interdecadal variation of drought patterns and associated influencing factors in the north-south transitional zone of China

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

A path integral formula of quantum gravity emergent from entangled local structures

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

Search for dark matter produced in association with a Standard Model Higgs boson decaying into b-quarks using the full Run 2 dataset from the ATLAS detector

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
