Broadly Available Imaging Devices Enable High-Quality Low-Cost Photometry
(American Chemical Society (ACS), 2015)This paper demonstrates that, for applications in resource-limited environments, expensive microplate spectrophotometers that are used in many central laboratories for parallel measurement of absorbance of samples can be ... -
Broadly heterogeneous activation of the master regulator for sporulation in Bacillus subtilis
(Proceedings of the National Academy of Sciences, 2010)A model system for investigating how developmental regulatory networks determine cell fate is spore formation in Bacillus subtilis. The master regulator for sporulation is Spo0A, which is activated by phosphorylation via ... -
Broken Mirror Symmetry in Excitonic Response of Reconstructed Domains in Twisted MoSe2/MoSe2 Bilayers
(Springer Science and Business Media LLC, 2020-07-13)Van der Waals heterostructures obtained via stacking and twisting have been used to create moiré superlattices, enabling new optical and electronic properties in solid-state systems. Moiré lattices in twisted bilayers of ... -
Broken Symmetry States and Divergent Resistance in Suspended Bilayer Graphene
(Nature Publishing Group, 2009)Mono- and bilayer graphene have generated tremendous excitement owing to their unique and potentially useful electronic properties\(^1\). Suspending single-layer graphene flakes above the substrate\({^2}{^,}{^3}\) has been ... -

Bronze, Jade, Gold, and Ivory: Valuable Objects in Ancient Sichuan
(Cotsen Institute of Archaeology Press, 2012)If negotiations about value are essentially political (Graeber 2001:115), our understanding of past political systems is illuminated by an understanding of how and through what processes value is attributed to objects in ... -
Brood Reduction and Optimal Parental Investment when Offspring Differ in Quality
(University of Chicago Press, 1990)No abstract -
Brooding in Mecistocephalus togensis (Geophilomorpha: Placodesmata) and the Evolution of Parental Care in Centipedes (Chilopoda)
(Brill Academic Publishers, 2010)The only well-documented data on female brooding posture in the geophilomorph family Mecistocephalidae come from Dicellophilus carniolensis (C.L. Koch, 1847), in which the mother coils around the eggs and hatchlings with ... -
Brownian Motion in Gravitationally Interacting Systems
(American Physical Society, 2002)wWe derive a model that describes the dynamics of a Brownian particle, such as a massive black hole, in a stellar system dominated by gravitational forces, and examine whether it achieves a state of equipartition of kinetic ... -
Brownian Motion of Molecular Probes in Supercooled Liquids
(American Physical Society (APS), 2015)When a supercooled liquid approaches glass transition, viscous flow slows down greatly, but often the Brownian motion of a molecular probe in the host liquid does not slow down as much, causing the Stokes-Einstein relation ... -

Bub1, Sgo1, and Mps1 mediate a distinct pathway for chromosome biorientation in budding yeast
(American Society for Cell Biology, 2011)The conserved mitotic kinase Bub1 performs multiple functions that are only partially characterized. Besides its role in the spindle assembly checkpoint and chromosome alignment, Bub1 is crucial for the kinetochore recruitment ... -
Bubbles navigating through networks of microchannels
(Royal Society of Chemistry (RSC), 2011)This paper describes the behavior of bubbles suspended in a carrier liquid and moving within microfluidic networks of different connectivities. A single-phase continuum fluid, when flowing in a network of channels, partitions ... -
Buckling of a Pressurized Hemispherical Shell Subjected to a Probing Force
(ASME International, 2017-10-19)We study the buckling of hemispherical elastic shells sub- jected to the combined effect of pressure loading and a prob- ing force. We perform an experimental investigation using thin shells of nearly uniform thickness ... -
Buckling of Elastomeric Beams Enables Actuation of Soft Machines
(Wiley-Blackwell, 2015)Soft, pneumatic actuators that buckle when interior pressure is less than exterior provide a new mechanism of actuation. Upon application of negative pneumatic pressure, elastic beam elements in these actuators undergo ... -
Buckling Pneumatic Linear Actuators Inspired by Muscle
(Wiley-Blackwell, 2016)The mechanical features of biological muscles are difficult to reproduce completely in synthetic systems. A new class of soft pneumatic structures (vacuum-actuated muscle-inspired pneumatic structures) is described that ... -
Buckling-induced encapsulation of structured elastic shells under pressure
(Proceedings of the National Academy of Sciences, 2012)We introduce a class of continuum shell structures, the Buckliball, which undergoes a structural transformation induced by buckling under pressure loading. The geometry of the Buckliball comprises a spherical shell patterned ... -
Buckling-Induced Kirigami
(American Physical Society, 2017)We investigate the mechanical response of thin sheets perforated with a square array of mutually orthogonal cuts, which leaves a network of squares connected by small ligaments. Our combined analytical, experimental and ...
