Purpose: This study aimed to assess the accuracy of patient-specific absorbed dose calculations for tumours and organs at risk in radiopharmaceutical therapy planning, utilizing hybrid planar-SPECT/CT imaging. Methods: Three Monte Carlo (MC) simulated digital patient phantoms were created, with time-activity data for mIBG labelled to I-123 (LEHR and ME collimators) and I-131 (HE collimator). The s

Background: To assess whether retrograde cerebral perfusion reduces neurological injury and mortality in patients undergoing surgery for acute type A aortic dissection. Methods: Single-center, retrospective, observational study including all patients undergoing acute type A aortic dissection repair with deep hypothermic circulatory arrest between January 1998 and December 2022 with or without the

Background: Polygenic prediction studies in continental Africans are scarce. Africa’s genetic and environmental diversity pose a challenge that limits the generalizability of polygenic risk scores (PRS) for body mass index (BMI) within the continent. Studies to understand the factors that affect PRS variability within Africa are required. Methods: Using the first multi-ancestry genome-wide associa

For a fixed analytic function g on the unit disc, we consider the analytic paraproducts induced by g, which are formally defined by Tgf(z)=∫0zf(ζ)g′(ζ)dζ, Sgf(z)=∫0zf′(ζ)g(ζ)dζ, and Mgf(z)=g(z)f(z). We are concerned with the study of the boundedness of operators in the algebra Ag generated by the above operators acting on Hardy, or standard weighted Bergman spaces on the disc. The general question

PURPOSE: To assess the effect of an intensive initial IOP lowering treatment strategy on the progression of visual field damage. DESIGN: A randomized, controlled, open-labelled two-center clinical trial. METHODS: A total of 242 patients with newly detected early or moderate untreated open-angle glaucoma were enrolled at two university hospitals in Sweden. Participants were randomly allocated (1:1)

Suppose (f,X, μ) is a measure preserving dynamical system and φ: X → R a measurable function. Consider the maximum process Mn := max{X1, ,Xn}, where Xi = φ ○ fi-1 is a time series of observations on the system. Suppose that (un) is a non-decreasing sequence of real numbers, such that μ(X1 > un) → 0. For certain dynamical systems, we obtain a zero- one measure dichotomy for μ(Mn ≤ un i.o.) dependin

Controlling the water level in irrigation channels is important for the efficient management of irrigation and water delivery. In this study, the proportional–integral–derivative (PID) controller was implemented in both the HEC-RAS boundary condition, as an internal model, and MATLAB, as an external model. In the latter, the Hydrologic Engineering Center’s (HEC) River Analysis System (HEC-RAS) mod

While our understanding of the nanoscale architecture of anterograde synaptic transmission is rapidly expanding, the qualitative and quantitative molecular principles underlying distinct mechanisms of retrograde synaptic communication remain elusive. We show that a particular form of tonic cannabinoid signaling is essential for setting target cell–dependent synaptic variability. It does not requir

In the last decade, businesses have played an increasingly significant role in promoting stability, democracy, and human rights, particularly concerning the United Nations Sustainable Development Goals, which emphasize peace, justice, and strong institutions. Consequently, there has been a greater focus on corporate social responsibility and corporate citizenship. Research has explored business mo

I antologin Antirasismer och antirasister: Realistiska utopier, spänningar och vardagserfarenheter utforskar 24 forskare hur motståndet mot olika former av rasism bedrivs och förkroppsligas bedrivs bland grupper av människor som på en mängd sätt, ofta motsägelsefullt, sällan framgångsrikt, men alltid envist och framåtblickande drömmer bortom rasismer. Antologin illustrerar antirasismens bredd, men

Beta-delayed proton and gamma emission in the decay of 21Mg has been measured at ISOLDE, CERN with the ISOLDE Decay Station (IDS) set-up. The existing decay scheme is updated, in particular what concerns proton transitions to excited states in 20Ne. Signatures of interference in several parts of the spectrum are used to settle spin and parity assignments to highly excited states in 21Na. The previ

Poster presented at the Workshop on Intonation at the crossroads (CROSSIN)This study revisits arguments for and against the mapping of syntactic clauses to intonational phrases (ι) and argues that the clause–ι mapping is only apparent, and hence should be eliminated from the syntax–prosody mapping. Instead, it will be proposed that the ι is more directly related to discourse-related units, namely,

To reduce carbon emissions, logistics companies take measures to achieve the climate neutrality target to reach “Green Logistics.” As one of the valuable measures, gradually replacing present fossil fuel vehicles with electric vehicles for parcel delivery and linehaul transportation is scheduled at the terminals of logistics companies. The charging load of a fully electrified vehicle fleet challen

This study presents a comprehensive analysis of the combustion behavior, performance, and NOx emissions in a diesel-hydrogen dual-fuel high-pressure direct injection (HPDI) compression ignition (CI) heavy-duty engine, utilizing numerical simulations validated against operational-engine experimental data. This study aims to investigate this engine by focusing on two distinct hydrogen rail pressures
