Matrix Nearness Problems, D-Stability and μ-Values in Economic Models

IEEE Access
In this paper, we investigate the interconnection between $D$ -stability and the structured singular value ( $\mu $ -values) to analyze linear time invariant dynamical systems subject to structured uncertainties.

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

FEBS Open Bio, EarlyView.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Comparing the Performance of Robust Controllers for Vibration Suppression in Long Rotor Systems

Acoustics
In this paper, the vibration control of the multivariable model of rotor bearing systems is considered for investigation. Some simply structured controllers that can suppress vibrational disturbances are tested for their robustness via the H∞ optimality ...

Adaptive robust control of longitudinal and transverse electron beam profiles

Physical Review Accelerators and Beams, 2016
Feedback control of the longitudinal and transverse electron beam profiles are considered to be critical for beam control in accelerators. In the feedback scheme, the longitudinal or transverse beam profile is measured and compared to a desired profile ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Between earth and sky. War architecture in Sardinia: a landscape to preserve

ArcHistoR Architettura Storia Restauro: Architecture History Restoration, 2019
In the first years of the Second World War along the coast of Sardinia, a system of military defenses was built consisting essentially of bunkers and concrete batteries, many of which are still standing, as "testarde rovine" that resist the passage of ...
