Isotopic differences in the distribution of nuclear charge and magnetization give rise to "hyperfine structure anomalies" which were observed already in the 1950s. More recently, the distribution of nuclear magnetization has been found to complicate the interpretation of the measured hyperfine splittings in highly charged hydrogen-like ions. In this paper, results of numerical calculations for a f
By the use of relativistic many-body theory, the hyperfine structure of the 7p state of Fr211 was calculated. By including polarization effects in all orders, good agreement for the magnetic dipole constant was obtained. In the same way, a new value of the electric quadrupole moment is obtained: Q=-240 mb for Fr211(P322).
Radiative lifetimes have been determined for the 62P12/0 and 62P32/0 levels in Yb II using the method of laser-induced fluorescence from sputtered metal vapour. The results, 8.0(2)ns (62P12/0) and 6.3(3)ns (62P32/0), are compared with lifetimes obtained from ab initio manybody perturbation calculations.
There are many laws of physics involved in the design and operation of roller coasters, carousels, and other amusement rides. Physics for the Whole Body in Playgrounds and Amusement Parks teaches these concepts in an exciting and approachable way by linking them with students’ personal experiences of rides in amusement parks.This unique book features:Immersive elements to learn scientific principl
Quantum mechanics has been enormously successful. The equations and rules enable accurate calculations and predictions of energies and other properties of atoms, molecules, and materials. Quantum-physics-based technology is an integrated part of our daily lives. Still, the understanding and interpretation of quantum physics offer many challenges, with the counterintuitive consequences of the rules
This study presents a digital solution for inducing visually-induced motion sickness (VIMS) using a head-mounted display (HMD) in a virtual environment. By digitally replicating off vertical axis rotation by adopting the Epley Omniax Chair, we induce sensory conflicts between the visual and vestibular systems through rotational vection, alongside optokinetic stimulation inspired by the Optoki-neti
Tumor resection of advanced pelvic and recurrence pelvic cancers is highly challenging, because the resections often are performed outside the standard surgical resections planes, and therefore are associated with considerable morbidity and mortality. Knowledge of normal anatomy combined with improved imaging modalities and new technology give the best-possible preparation to clarify the tumor spe
This manuscript reports the results of an international consensus on technologies of hyperthermic intraperitoneal perioperative chemotherapy (HIPEC) performed with the following goals: To provide recommendations for the technological parameters to perform HIPEC. To identify the role of heat and its application forms in treating peritoneal metastases. To provide recommendations regarding the correc
Purpose: Flaps are used for repair of defects after tumor excision and often need stretching and rotating to cover the defects. Manipulation of flaps may affect blood perfusion, which is crucial for healing. The aim was to examine the impact on perfusion by stretching and rotating forehead skin flaps. Methods: Blood perfusion was monitored using laser speckle contrast imaging in 19 flaps, raised a

PURPOSE: Despite rising global demand, geriatrics is often overlooked by young physicians due to its perceived complexity and limited career development. Launched by the European Geriatric Medicine Society, the Early Career Geriatricians Initiative (ECGI) aims to counter this perception with its rich educational, research, and leadership opportunities.METHODS: This article provides a narrative ove
The pathophysiological mechanisms driving disease progression of frontotemporal lobar degeneration (FTLD) and corresponding biomarkers are not fully understood. Here we leveraged aptamer-based proteomics (>4,000 proteins) to identify dysregulated communities of co-expressed cerebrospinal fluid proteins in 116 adults carrying autosomal dominant FTLD mutations (C9orf72, GRN and MAPT) compared with 3
What does it mean for a business or industry to be and do good? And who can count themselves within the good economy? This article investigates the justification of goodness in mineral exploration and mining and uses the entwinement between value creation and destruction characteristic of mining to trouble notions of goodness in impactful industries. Based on analyses of indepth interviews, ethnog
Human rights defenders, social leaders, and environmental and indigenous activists fight for political, cultural, social, economic, and environmental rights and often face intimidation and violence as a consequence. In this article, we analyze how the implementation of the peace agreement signed in 2016 between the government of Colombia and the FARC-EP guerrilla group affects environment and huma
Geometry projection-based topology optimization has attracted a great deal of attention because it enables the design of structures consisting of a combination of geometric primitives and simplifies the integration with computer-aided design (CAD) systems. While the approach has undergone substantial development under the assumption of linear theory, it remains to be developed for non-linear hyper
