Suppression of Oscillation and Ghosting in RF‐Spoiled Gradient‐Echo‐Based Dynamic Imaging

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aims to address the suppression of oscillation and ghosting appearing in RF‐spoiled gradient‐echo‐based dynamic imaging, which is caused by the pseudo‐steady state (PSS) of magnetization. Theory and Methods We extended the concept of the previous RF phase‐cycle‐adapted averaging method to RF‐spoiled gradient‐echo‐based cine (

Multi‐Agent Reinforcement Learning for Joint Police Patrol and Dispatch

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Police patrol units need to split their time between performing preventive patrol and being dispatched to serve emergency incidents. In the existing literature, patrol and dispatch decisions are often studied separately. We consider joint optimization of these two decisions to improve police operations efficiency and reduce response time to ...

The 2‐D Orthogonal Packing Problem With Multiple Levels of Prioritization: A Spatial Optimization Perspective

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT This paper addresses two‐dimensional orthogonal packing within a confined space, integrating bin packing principles with facility layout concepts to address scenarios in which items must not only fit but also be arranged according to spatial priorities.

Self‐Service and Home Delivery Combined: Coordinating the Route of a Mobile Parcel Locker With the Delivery Tasks of Its Human Driver

open access: yesNetworks, EarlyView.
ABSTRACT In response to the increasing volume of parcels, last‐mile delivery innovations are exploring the integration of multiple delivery modes. The most prominent examples are delivery vans that, next to being the base for the delivery tasks of their human drivers, also function as mobile launching platforms for drones or autonomous delivery robots.

Approximate Reachability for Feedback Linearizable Systems

open access: yesOptimal Control Applications and Methods, EarlyView.
The backwards reachable set for a dynamical system is the set of states for which there exists a constraint admissible trajectory that reaches a given terminal set. Conventional grid‐based approaches for computing these sets are intractable for many applications.

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

open access: yesThe Journal of Pathology, EarlyView.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...

RNase A oligomerization through 3D domain swapping is favoured by a residue located far from the swapping domains

Biochimie, 2011
Bovine pancreatic ribonuclease A forms 3D domain-swapped oligomers by lyophilization from 40% acetic acid solutions or if subjected to various thermally-induced denaturation procedures. Considering that the intrinsic swapping propensity of bovine seminal RNase, the only member of the pancreatic-type RNase super-family that is dimeric in nature, is ...

Domain‐Swapping Design by Polyproline Rod Insertion

ChemBioChem, 2019
AbstractDuring domain swapping, proteins mutually interconvert structural elements to form a di‐/oligomer. Engineering this process by design is important for creating a higher order protein assembly with minimal modification. Herein, a simple design strategy is shown for domain‐swapping formation by loop deletion and insertion of a polyproline rod ...
