In this paper, we approach the two weighted boundedness of commutators via matrix weights. This approach provides both a sufficient and a necessary condition for the two weighted boundedness of commutators with an arbitrary linear operator in terms of one matrix weighted norm inequalities for this operator. Furthermore, using this approach, we surprisingly provide conditions that almost characteri
Experimental Modal Analysis (EMA) plays a crucial role in understanding the dynamic responses of structures to vibration by extracting their modal parameters such as natural frequencies and modal damping and vibration modes. These parameters are essential for assessing structural performance and identifying potential vulnerabilities. As the construction industry embraces sustainable materials, Cro
Extensive studies have shown that humans process faces holistically, considering not only individual features but also the relationships among them. Knowing where humans and dogs fixate first and the longest when they view faces is highly informative, because the locations can be used to evaluate whether they use a holistic face processing strategy or not. However, the conclusions reported by prev
Controlling the streaming flow in acoustically actuated microchannels enables the targeted motion of suspended micro-objects. This can offer novel approaches for rare cell studies or cell sorting in medicine or basic biology. In this work, we utilize the temperature dependence of the acoustic body force, which originates from the interaction of an acoustic field with gradients in compressibility o
Atmospheric methane (CH4) growth rates reached unprecedented values in the years 2020-2022. To identify the main drivers of this increase, an inverse modeling study estimated regional and sectoral emission changes for 2016-2022. Three inverse estimates based on different sets of atmospheric CH4 observations (surface observations only, surface and aircraft observations, and GOSAT observations) cons
INTRODUCTION: Plasma biomarkers offer promise for improving the diagnosis of Alzheimer's disease (AD) and differentiating AD and other neurodegenerative disorders (NDs) like frontotemporal dementia (FTD) from primary psychiatric disorders (PPDs), particularly in younger patients. METHODS: In this prospective study, we investigated plasma phosphorylated tau 217 (p-tau217), neurofilament light chain
PURPOSE: Sudden sensorineural hearing loss (SSNHL) is defined as 30 decibels (dB) hearing loss in 3 consecutive frequencies occurring within 72 h. Pure-tone average of four frequencies (PTA4) is commonly used to evaluate hearing levels but may not accurately reflect the recovery. We aimed to identify prognostic factors for recovery and to evaluate how recovery should be assessed, by comparing PTA4
Southern Kazakhstan, particularly the Zhambyl Region, is facing increasing groundwater stress due to climate change, degradation of irrigation infrastructure, and unsustainable water use. Despite substantial renewable groundwater reserves (8.33 km3/year), irrigation still relies on ephemeral surface flow. This study delineates priority zones for Managed Aquifer Recharge (MAR) using a GIS-based Mul
Uganda is experiencing rapid rates of urbanisation that include huge demographic changes and the incorporation of surrounding rural areas into the urban fabric. This demographic and land use transformation has altered several supply and delivery systems (in)to urban areas including food provisioning. Local authorities in secondary cities need to understand the nature of their food supply and, cons
Dizziness associated with vestibular schwannomas can be considered a diagnostic feature, a posttreatment challenge, or an issue in patients undergoing a wait-and-scan approach. Regardless of the scenario, dizziness has the potential to significantly impact patient quality of life and therefore requires careful assessment and management. This chapter examines these different scenarios and explores
The decays of the χb1(1P), χb2(1P), χb1(2P) and χb2(2P) mesons into the Υ(1S)μ+μ− final state are observed with a high significance using proton-proton collision data collected with the LHCb detector and corresponding to an integrated luminosity of 9 fb−1. The newly observed decays together with the Υ(2S) → Υ(1S)π+π− and Υ(3S) → Υ(2S)π+π− decay modes are used for precision measurements of the mass
A search for the lepton-flavor violating decays Bs0→φμ±τ is presented, using a sample of proton-proton collisions at center-of-mass energies of 7, 8, and 13 TeV, collected with the LHCb detector and corresponding to a total integrated luminosity of 9 fb-1. The τ leptons are selected using decays with three charged pions. No significant excess is observed, and an upper limit on the branching fracti
A study of resonant structures in B+→D∗+D-K+ and B+→D∗-D+K+ decays is performed, using proton-proton collision data at center-of-mass energies of s=7, 8, and 13 TeV recorded by the LHCb experiment, corresponding to an integrated luminosity of 9 fb-1. A simultaneous amplitude fit is performed to the two channels with contributions from resonances decaying to D∗-D+ and D∗+D- states linked by C parit
A search for the nonresonant Λc+→pμ+μ- decay is performed using proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the LHCb experiment, corresponding to an integrated luminosity of 5.4 fb-1. No evidence for the decay is found in the dimuon invariant-mass regions where the expected contributions of resonances is subdominant. The upper limit on the branching fraction of th
InP quantum dots have emerged as a promising ecofriendly alternative to cadmium-based QDs for next-generation display applications. However, red-emitting InP QDs synthesized via aminophosphine precursors still suffer from broad emission spectra and limited stability. In this study, we present a strain-engineered InP/ZnSe/ZnSexS1-x/ZnS QD structure featuring a gradient alloyed ZnSexS1-x shell that
The decays of the B+ meson to the final state D∗−Ds+π+ are studied in proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb−1. The ratio of branching fractions of the B+→D∗−Ds+π+ and B0→D∗−Ds+ decays is measured to be 0.173 ± 0.006 ± 0.010, where the first uncertainty is statistical and t
Although Fourier Neural Operators (FNOs) are computationally efficient and theoretically mesh-independent, their standard formulation assumes periodic boundary conditions and rectangular domains. When applied to non-periodic conditions, FNOs often exhibit oscillations, edge effects, and reduced accuracy. To mitigate these issues, this study investigates modifications to the baseline FNO, including
Otaliga mängder kritisk information om vår hälsa spolas ner varje dag. En toalettsits med osynligt inbyggd radar kan ta tillvara på denna information. Alla besöker toaletten varje dag, därav är den fylld av kliniskt relevant information, som hittills sällan använts för att övervaka hälsan. Förändringar i urin- och avföringsmängd, samt avföringens konsistens kan vara tidiga tecken på sjukdom, men rConstipation and irregular bowel movements are a daily challenge in elderly care, especially among patients with dementia who struggle to report their own toilet habits. This thesis investigates the possibility of using millimeter-wave pulsed coherent radar to passively monitor toilet visits and estimate both stool consistency and excreted quantity of urine and feces. This involved constructing a
