3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Advanced Robotics Research, EarlyView.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...

Cross Kingdom Metabolic Engineering Paradigm Elevating Sustainable Protein Production

Advanced Science, EarlyView.
ABSTRACT Confronting the dual crisis of escalating global protein demand and unsustainable agriculture necessitates transformative solutions. Here, we pioneer evolutionary insights from maize nitrogen optimization via asparagine synthetase (ASNS) to rewire metabolism in Pichia pastoris.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Mitigating Cancer Therapy–Related Cognitive Impairment by Targeted Activation of Undruggable Phosphatase

Advanced Science, EarlyView.
An RVG‑engineered exosomal saRNA delivery system (RVG‑EVs‑saPtpro) effectively targets and activates hippocampal PTPRO, functioning as a “molecular brake” to alleviate cancer therapy‑related cognitive impairment (CTRCI) by enhancing neuronal survival, neurogenesis, and synaptic plasticity.

Location-Aware Cluster-Based Routing Protocol Design for Wireless Networks [PDF]

, 2007
摘 要 無線網路提供使用者於有效傳輸範圍內自由活動的便利性，無線傳輸技術的進步，更實現了行動計算的可能性。無線隨意網路是一種沒有固定基地台的架構，在此架構中每一節點均可能成為一個路由器，負責路由的任務。由於隨意網路具有高移動性，傳統有線網路的路由協定並不適用隨意網路，因此必須重新設計合適的路由演算法。在無線網路中，能源是極受限制的資源，因此在設計路由演算法時，必須將其列為參考因素，以便延長整個網路系統的生命週期。 為了有效減少路由交通流量、碰撞、干擾，節省能源消耗，進而延長網路運作時間，在本論文中 ...
