Dimensional reduction in complex living systems: Where, why, and how

Sign Up to like & get

DOI: 10.1002/bies.202100062

Abstract: The unprecedented prowess of measurement techniques provides a detailed, multi‐scale look into the depths of living systems. Understanding these avalanches of high‐dimensional data—by distilling underlying principles and mechanisms—necessitates dimensional reduction. We propose that living systems… read more here.

DOI: 10.1007/jhep12(2019)025

Abstract: Abstract We propose a way to obtain holographic cosmology models for 3+1 dimensional cosmologies vs. 3 dimensional field theories from a “dimensional reduction” procedure, obtained by integrating over the time direction, of (modifed) standard holographic… read more here.

DOI: 10.1007/s10714-018-2409-x

Abstract: Many theories of quantum gravity live in higher dimensions, and their reduction to four dimensions via mechanisms such as Kaluza–Klein compactification or brane world models have associated problems. We propose a novel mechanism of dimensional… read more here.

DOI: 10.1007/s11538-017-0249-6

Abstract: We present a method of dimensional reduction for the general Markov model of sequence evolution on a phylogenetic tree. We show that taking certain linear combinations of the associated random variables (site pattern counts) reduces… read more here.

DOI: 10.1007/s12551-024-01233-2

Abstract: Living systems are complex and hierarchical, with diverse components at different scales, yet they sustain themselves, grow, and evolve over time. How can a theory of such complex biological states be developed? Here we note… read more here.

DOI: 10.1016/j.mbs.2017.01.003

Abstract: Parameter identification is an important and widely used process across the field of biomedical engineering. However, it is susceptible to a number of potential difficulties, such as parameter trade-off, causing premature convergence at non-optimal parameter… read more here.

DOI: 10.1021/acs.inorgchem.3c00571

Abstract: Tuning the dimensionality in halide perovskites provides an opportunity to obtain the properties desired for optoelectronic devices. In this work, we demonstrate the dimensional reduction of 3D halide double-perovskite Cs2AgBiBr6 by systematically introducing alkylammonium organic… read more here.

DOI: 10.1021/jacs.3c12756

Abstract: Dion-Jacobson (DJ) phase 2D perovskites with various aromatic diammonium cations, potentially possessing high stability, have been developed for optoelectronics. However, their stability does not meet initial expectations, and some of them even easily degrade into… read more here.

DOI: 10.1021/jacs.8b01543

Abstract: We investigate the consequences of dimensional confinement on halide double perovskites by synthesizing two-dimensional analogues of the recently reported three-dimensional double perovskite Cs2AgBiBr6. The layered perovskites (BA)4AgBiBr8 (1) and (BA)2CsAgBiBr7 (2) (BA = CH3(CH2)3NH3+) feature… read more here.

DOI: 10.1088/1475-7516/2021/05/048

Abstract: We show that in the presence of disorder induced by random networks of observers measuring covariant quantities (such as scalar curvature) (3+1)-dimensional quantum gravity exhibits an effective dimensional reduction at large spatio-temporal scales, which is… read more here.
