Reliability-based optimal design of water distribution networks [PDF]

open access: yes, 2001
A considerable amount of research has been carried out on the reliability analysis and optimal design of water distribution systems, and it has been reported that each of the above problems is very difficult to solve (Eiger et al.

Design and psychometric validation of a social capital questionnaire for adults with end-stage chronic kidney disease undergoing dialysis or hemodialysis

open access: yesBMC Nephrology
Background The effects of end-stage kidney disease (ESKD) can spill over into a patient’s social life. Social capital (SC) is a determinant of health that can enhance patients’ health through support and resources.

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

open access: yesAdvanced Functional Materials, EarlyView.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Partitions and network reliability [PDF]

open access: yes, 1999
The all-terminal reliability and K-terminal reliability of networks are often considered as separate problems. We use the partition lattice of the vertex set of an undirected graph to show that these reliability measures are closely related.

HarmoAtt-IK: an adaptive multimodal feature fusion network for real-time neural inverse kinematics

open access: yesFrontiers in Neurorobotics
IntroductionRecent advances in neural networks have introduced a new paradigm for robotic inverse kinematics. However, existing methods remain limited by insufficient feature extraction and suboptimal integration of multi-source information, preventing ...

Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes

open access: yesAdvanced Functional Materials, EarlyView.
Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

Atomically Dispersed Ni Site Catalysts Accelerating Sluggish Sulfur Redox Kinetics in Nonaqueous Zn‐S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An atomically dispersed Ni catalyst featuring Ni‐N4 coordination is developed as a sulfur host for nonaqueous Zn─S batteries. This configuration modulates the electronic structure to lower activation barriers during rate‐limiting steps and promotes a robust ZnF2‐rich cathode‐electrolyte interphase, thereby accelerating sulfur redox kinetics ...
