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/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.

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.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.

DOI: 10.1109/toh.2022.3174229

Abstract: Haptics researchers often endeavor to deliver realistic vibrotactile feedback through broad-bandwidth actuators; however, these actuators typically generate only single-axis vibrations, not 3D vibrations like those that occur in natural tool-mediated interactions. Several three-to-one (321) dimensional… read more here.
