Complex Systems + Systems Engineering = Complex Systems Engineeri [PDF]

arXiv, 2006
One may define a complex system as a system in which phenomena emerge as a consequence of multiscale interaction among the system's components and their environments. The field of Complex Systems is the study of such systems--usually naturally occurring, either bio-logical or social.

Lymphoid/nonlymphoid compartmentalization of donor leukocyte chimerism in rat recipients of heart allografts, with or without adjunct bone marrow [PDF]

, 1998
Background. The role of leukocyte migration and chimerism in organ allograft acceptance has been obscured by the lack of information about the late localization of the donor cells. Methods.

An Insect Salivary Sheath Protein Triggers Plant Resistance to Insects and Pathogens as a Conserved HAMP

Advanced Science, EarlyView.
The salivary sheath protein myosin from SBPH is critical for the formation of the salivary sheath and feeding. However, myosin functions as a HAMP and triggered plant BAK1‐mediated PTI responses, which include the activation of calcium signaling pathways, MAPK phosphorylation, ROS bursts, and cell death, thereby triggering JA pathway.

Systems of quotients of Lie triple systems [PDF]

Communications in Algebra, 42(2014)(8), 3339-3349, 2013
In this paper, we introduce the notion of system of quotients of Lie triple systems and investigate some properties which can be lifted from a Lie triple system to its systems of quotients. We relate the notion of Lie triple system of Martindale-like quotients with respect to a filter of ideals and the notion of system of quotients, and prove that the ...

Longitudinal, Multimodal Tracking Reveals Lasting Neurovascular Impact of Individual Microinfarcts

Advanced Science, EarlyView.
Jin et al. investigate the neurovascular impact of microinfarcts, revealing transient neural suppression with minimal cell death and recovery linked to vascular remodeling. Fast‐spiking interneurons exhibit reduced excitability, whereas regular‐spiking neurons showed increased bursting activity. Disruptions in low‐gamma phase locking suggest persistent

Clinical xenotransplantation [PDF]

, 1994
: Two baboon liver xenografts transplanted to patients with B virus hepatitis supported life for 70 and 26 days but did not function optimally despite minimum or no histopathologic findings of overt humoral or cellular rejection in serial biopsies ...

Mechanical Biomimetic Nanocomposites for Multidimensional Treatment of Arterial Thrombosis

Advanced Science, EarlyView.
In this study, a mechanical biomimetic nanocomposite is developed, guided by photoacoustic imaging, to achieve highly efficient and safe thrombolysis through the synergistic effects of photothermal therapy and pharmacological intervention. Most notably, the nanoparticle improves the microenvironment of arterial thrombi, marked by high shear stress and ...

Generation of Neural Organoids and Their Application in Disease Modeling and Regenerative Medicine

Advanced Science, EarlyView.
Neural organoids provide a versatile platform for neurological research. Advances in organoid technology have partially achieved human neural tissue complexity in terms of tissue structure, cell diversity, and neural signaling, offering insights into neural disorders and regenerative strategies. Technology advances from biomaterials, bio‐manufacturing,

Development of a DNA Aptamer‐Based Approach to Noninvasively Image CAR‐T Cells In Vivo and Traceless Enrichment In Vitro

Advanced Science, EarlyView.
A DNA aptamer (A3) with nanomolar affinity for CAR‐T cells is developed via Cell‐SELEX. In Nalm6 tumor‐bearing mice, Cy5‐labeled A3 enables long‐term fluorescence imaging and tracks the biodistribution of CAR‐T cells, with tumor signal peaking on day 14 after CAR‐T cell administration.
