Acid ceramidase overactivity drives ceramide loss, leading to atopic dry skin and Th2‐skewed immune polarization

open access: yesThe Journal of Pathology, EarlyView.
Abstract Ceramide deficiency in the stratum corneum (SC) is a key etiological factor in atopic dermatitis (AD). To clarify the direct role of SC ceramide depletion in impairing SC barrier and water‐holding functions and in initiating AD‐like skin symptoms and disease‐specific molecular alterations, we generated Tg mice overexpressing a mutant form of ...

Prediction of spiralling in BTA deep-hole drilling: estimating the system's eigenfrequencies [PDF]

open access: yes
One serious problem in deep-hole drilling is the formation of a dynamic disturbance called spiralling which causes holes with several lobes. Since such lobes are a severe impairment of the bore hole quality the formation of spiralling has to be prevented.

Mechanical, Thermal, and Microstructural Evaluation of Bio‐Based Polyurethane Composites Reinforced With Woven Jute and Flax

open access: yesPolymer Composites, EarlyView.
Graphical overview of the manufacturing and characterization of bio‐based polyurethane composites reinforced with woven jute and flax fibers produced by the VARTM process. Mechanical, thermal, and microstructural analyses reveal differences in stiffness, thermal stability, and interfacial behavior between the natural fiber composites.

A modular docking mechanism for in-orbit assembly and spacecraft servicing [PDF]

open access: yes, 1985
A Docking Mechanism concept is described which is suitable for use with autonomous docking systems. The central feature of using simple cylindrical handles on one side and a type of prism seating on the other is offered as a practical method of achieving

Liquid PV Module Encapsulation to Enable Circular Design

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study demonstrates a novel liquid encapsulation technology to enable circularity in c‐Si photovoltaic modules. The optical properties and power conversion efficiency of liquid encapsulation is similar to EVA encapsulation and better than air encapsulation.

A Lyapunov Based Multi-level Controller for Semi-active Suspension System with an MRF Damper [PDF]

open access: yes
[[abstract]]In this work, we study the implementation of magnetorheological fluid (MRF) to the semi-active suspension. Owing to the nonlinear hysteretic phenomenon, the analysis and synthesis of a controller are not trivial.

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

open access: yesSmall, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Experimental analysis of bolted connections for precast concrete walls under cyclic tensile loading

open access: yesStructural Concrete, EarlyView.
Abstract Dry‐bolted connections in precast wall structures simplify the assembly process and offer significant advantages in terms of construction speed and cost. In fact, the reduction of the required workmanship, compared to wet connections, makes this solution highly competitive.
