The Lock is the Key: Development of Novel Drugs through Receptor Based Combinatorial Chemistry

open access: yesActa Chimica Slovenica, 2017
Modern drug discovery is mainly based on the de novo synthesis of a large number of compounds with a diversity of chemical functionalities. Though the introduction of combinatorial chemistry enabled the preparation of large libraries of compounds from so-

Development and Validation of a One‐Dimensional Finite Difference Simulation Scheme for Polymer Laser Powder Bed Fusion with Application to the Effect of the Inter Layer Time

open access: yesAdvanced Engineering Materials, EarlyView.
The study presents an efficient simulation approach for the polymer laser powder bed fusion process polymers process, validated with polyamide 12, polyamide 6, and polyetherketoneketone. It shows that inter layer time affects part density, with 90s yielding dense parts.

Two-beam nonlinear Kerr effect to stabilize laser frequency with sub-Doppler resolution

open access: yes, 2012
Avoiding laser frequency drifts is a key issue in many atomic physics experiments. Several techniques have been developed to lock the laser frequency using sub-Doppler dispersive atomic lineshapes as error signals in a feedback loop.

A Case‐Based Reasoning Approach to Model Manufacturing Constraints for Impact Extrusion

open access: yesAdvanced Engineering Materials, EarlyView.
A hybrid modeling approach is presented that combines constraint‐based process modeling and case‐based reasoning. The model formalizes manufacturing constraints and integrates simulation data to model complex manufacturing processes. The approach supports manufacturability analysis during product design through an adaptive modeling environment.

Preferences for Firearm Locking Devices and Device Features Among Participants in a Firearm Safety Event

open access: yesWestern Journal of Emergency Medicine, 2019
Introduction: Safe firearm storage is associated with a lower risk of firearm-related injury and death. Although providing firearm locking devices is a key component of firearm safety interventions, little is known about the types and characteristics of ...

Lock and key become flexible

open access: yesNature Chemical Biology, 2018
G-protein-coupled receptors (GPCRs) are critically involved in signal transduction. Structural views of several GPCRs have recently been obtained, but the structural principles determining subtype selectivity are still mostly elusive. Now, a combined solid-state NMR and molecular-modeling approach reveals how bradykinin GPCRs distinguish between ...

Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...
