The LPM effect in sequential bremsstrahlung [PDF]

open access: yes, 2016
The splitting processes of bremsstrahlung and pair production in a medium are coherent over large distances in the very high energy limit, which leads to a suppression known as the Landau-Pomeranchuk-Migdal (LPM) effect.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The Principle of Double Effect within Catholic Moral Theology: A Response to Two Criticisms of the Principle in Relation to Palliative Sedation

open access: yesJournal of Moral Theology, 2017
If not considered an isolated principle but as part of Catholic moral theology, the principle of double can serve as an aid to discernment of the morality of an action, as one moral principle in the context of a broader moral system.

Novel Adaptive Hierarchical Sliding Mode Control for Trajectory Tracking and Load Sway Rejection in Double-Pendulum Overhead Cranes

open access: yesIEEE Access, 2019
Overhead cranes with double-pendulum effect seem more practical than those with single-pendulum effect. However, in this case, the dynamic performance analysis and the controller design become more difficult.

Proposal for an Optical Test of the Einstein Equivalence Principle

open access: yes, 2019
The Einstein Equivalence Principle (EEP) underpins all metric theories of gravity. Its key element is the local position invariance of non-gravitational experiments, which entails the gravitational red-shift.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

El principio del doble efecto en la sedación a pacientes terminales The principle of double effect on sedation of terminally ill patients

open access: yesMedisan, 2012
Entre los 5 principios éticos en medicina paliativa, el del doble efecto o de razonamiento práctico no solo sirve para determinar la licitud o ilicitud de una acción y puede producir 2 efectos: uno bueno y otro malo, sino que es posible aplicarlo en los ...

Case Report: Case report: Administration of anticoagulant therapy after neuro-anesthesia procedure for hemorrhagic stroke patients with COVID-19 complications and its ethical and medicolegal consideration [version 2; peer review: 2 approved]

open access: yesF1000Research, 2023
Background Ethical dilemmas can occur in any situation in clinical medicine. In patients undergoing neuro-anesthesia for surgical procedure evacuation of intracerebral hemorrhage with a history of hemorrhagic stroke, anticoagulants should not be given ...

Possible Intentions and the Doctrine of Double Effect [PDF]

open access: yes, 2019
Under the standard formulation of the Doctrine of Double Effect, an act is permissible only if it is the result of an intention to do good and not the result of an intention to do bad.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
