The number and probability of canalizing functions [PDF]

open access: yes, 2003
Canalizing functions have important applications in physics and biology. For example, they represent a mechanism capable of stabilizing chaotic behavior in Boolean network models of discrete dynamical systems. When comparing the class of canalizing functions to other classes of functions with respect to their evolutionary plausibility as emergent ...

Exploration of Half‐Cycle Length of Converging Circular Wavy Duct with Diverging‐Outlet: Turbulent Water Dynamics

open access: yesAdvanced Theory and Simulations, EarlyView.
Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

Craniogenetic studies in Sus scrofa: With emphasis on the ‘orbitosphenoid’ problem

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract The orbitosphenoid is a skeletal element of the endocranium of extant mammals. However, it has also been described in many of their fossil ancestors. Craniogenetic studies show that it is composed of two types of bone: first, the cartilaginous ala orbitalis and parts of the trabecular plate are transformed by endochondral ossification; second,

A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery

open access: yesAdvanced Science, EarlyView.
The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.

Lycium barbarum Glycopeptide Alleviates Neomycin‐Induced Ototoxicity by Inhibiting Tryptophan Hydroxylase‐Mediated Serotonin Biosynthesis

open access: yesAdvanced Science, EarlyView.
Lycium barbarum glycopeptide (LBGP), which is further extracted from Lycium barbarum polysaccharides, exhibits significant protective effects against neomycin‐induced hearing dysfunction including oxidative stress in cochlea and loss of key cells in cochlea.

ROOT Status and Future Developments [PDF]

open access: yesECONFC0303241:MOJT001,2003, 2003
In this talk we will review the major additions and improvements made to the ROOT system in the last 18 months and present our plans for future developments. The additons and improvements range from modifications to the I/O sub-system to allow users to save and restore objects of classes that have not been instrumented by special ROOT macros, to the ...

Spatiotemporal Transcriptomic Profiling Reveals the Dynamic Immunological Landscape of Alveolar Echinococcosis

open access: yesAdvanced Science, EarlyView.
An unprecedented high‐resolution spatial atlas of the E. multilocularis infection foci is obtained, revealing the dynamic functions of neutrophils, Spp1+ macrophages, and fibroblasts during disease progression. The transition of parasite control strategy from “active killing” to “negative segregation” by the host may provide instructive insights into ...

Functional Polarization of Liver Macrophages by Glyco Gold Nanoparticles

open access: yesAdvanced Science, EarlyView.
Macrophages play a critical role in several pathophysiological diseases by being involved in the activation of adaptive and innate immune responses. The repolarization of macrophages using gold nanoparticles functionalized with glycans for a more selective targeting toward a restorative phenotype leads to an amelioration of the events.
