The ability to manipulate small fluid droplets, colloidal particles and single cells with the precision and parallelization of modern-day computer hardware has profound applications for biochemical detection, gene sequencing, chemical synthesis and highly parallel analysis of single cells. Drawing inspiration from general circuit theory and magnetic bubble technology, here we demonstrate a class of integrated circuits for executing sequential and parallel, timed operations on an ensemble of single particles and cells. The integrated circuits are constructed from lithographically defined, overlaid patterns of magnetic film and current lines. The magnetic patterns passively control particles similar to electrical conductors, diodes and capacitors. The current lines actively switch particles between different tracks similar to gated electrical transistors. When combined into arrays and driven by a rotating magnetic field clock, these integrated circuits have general multiplexing properties and enable the precise control of magnetizable objects.


Here, we use a combination of magnetic patterns and current lines to instead control an aqueous suspension of magnetic particles and magnetic-nanoparticle-labelled cells that behave like magnetization bubbles suspended in thin fluid films. The magnetic patterns are used to create passive circuitry analogous to the lumped element conductors, capacitors and diodes of electronic circuits. The current lines are used to establish active circuitry for switching particles and cells between different tracks. When combined together into small arrays, we demonstrate a scalable platform with general multiplexing properties, thereby paving the way for the development of digital circuitry for parallelized control of matter.

We intentionally design an asymmetry in the substrate periodicity so that the energy minima can be moved smoothly along desired pathways. We achieve this with a geometry of linearly magnetizable disks, whose magnetization attempts to synchronize with the rotating field direction. The lack of strong hysteresis of the magnetic patterns (Supplementary Fig. 1) justifies this linear approximation. From classical magnetostatics39, it is well known that the locations of energy minimum for linear magnetizable systems will occur at positions where the outward normal of the film curvature is aligned parallel to the external field (depicted as the blue regions in simulations of Figs 1, 2, 3, 4, 5). By rotating the external magnetic field in-plane, the locations of the energy minima are continuously shifted around the perimeter of the disk. For substrates consisting of a linear array of half disks connected by linear segments, the motion of the energy minima shifts continuously from one half disk to the next, moving exactly two disk periods, D, for each cycle of the rotating field. The particle transport process is thus similar to a ratchet (or step motor) that transports objects along controlled directions in discrete steps. Here, the local magnetic energy minima can be conceptualized as the nodes in the ratchet.


On demand digital circuitry for parallel operation of single particles. This movie shows the programmable control over the deposition of arbitrary patterns of single beads in a 3 x 3 array. Three horizontal and three vertical current lines act as switches 1, 2, 3 and A, B, C, respectively. The white line depicts the expected trajectory of a single particle to populate the 1C array location when row switch 1 and column switch C are simultaneously ON while other switches are OFF. The deposition of magnetic beads in an "X" pattern in the array is then depicted. (AVI 3756 kb)


Closed-loop system stability of adaptive control architectures for autonomous aerospace vehicles can be seriously degraded by the presence of actuator dynamics. To this end, recent research by the authors focuses on a new reference model design approach such that not only closed-loop system stability is rigorously addressed using linear matrix inequalities, but also the proposed reference model achieves better performance characteristics as compared with a well-adopted method in the literature called pseudo-control hedging. Yet, this reference model assumes the exact knowledge of the actuator bandwidth parameter, where such an assumption may not always hold for practical aerospace applications. Motivated from this standpoint, this paper generalizes our recent results such that the exact knowledge of the actuator bandwidth parameter is no longer necessary. Specifically, we utilize an online estimate of the actuator bandwidth parameter in the proposed reference model and show the stability of the closed-loop dynamical system using tools and methods from Lyapunov theory and linear matrix inequalities. An illustrative numerical example involving the short-period dynamics of a hypersonic vehicle model is also included in this paper to elucidate the proposed adaptive architecture for control of uncertain dynamical systems with unknown actuator bandwidths.


On digital transformations, Benjamim has helped several companies implement an end-to-end new digital operating model and an agile-at-scale organization, prioritizing key value opportunities arising from digital and analytics and setting up the organization, governance, and processes necessary to capture the opportunities and improve time-to-market.


Philip Whitney began his career at AM station WINC in Winchester Virginia in 1941 serving as an engineer, broadcaster and manager. He became general manager in 1941. In 1959 he designed a CONELRAD alarm device for FM stations to warn listeners in the event of an enemy attack. He is also credited with creating the microwave remote control systems used by radio stations as well as one of the first automated systems which permitted station WRFL (FM) in Winchester to operate automatically by remote control.


John (Jack) Arbuckle Mosely founded Moseley Associates Inc in his garage in 1959, developing remote control equipment for radio and TV stations. The company grew with the broadcast industry, adding FM exciters, stereo generators, SCA generators, digital control systems and satellite earth station control systems to its product line. He was instrumental in having the FCC allocate dual studio-transmitter links for FM stereo, assisted NAB in field tests leading to the adoption of rules for TV remote control and worked on the development of AM stereo transmission standards. Having started as a one-man shop, Mosely sold the 125-employee company in 1977 to Flow-General.






The linearization of an input/output controller has been designed for an input time delay nonlinear time discretized nonlinear system. The time discretized nonlinear model has been obtained based on Taylor-Lie series expansion method and zero order hold assumption. The resulting control algorithm enables the time delay nonlinear system control, while the continuous time controller cannot handle a time delay nonlinear system due to its infinite dimensionality. The performance of the proposed controller is evaluated by using two different case studies: a Van Der Pol equation and a Continuous Stirred Tank Reactor (CSTR) system that all exhibit nonlinear behavior and input time delay. For all the case studies, the results validate the proposed methods.


The prevalence and rapid evolution of digital fabrication technology is due in large part to open source communities of users who actively develop and contribute to new software, hardware, and publishing platforms. In this hands-on studio we will explore both the history and potential of the open source movement as it relates to art, design, and its production. Specifically, we will build upon, modify, hack, and create new open source tools, workflows, and platforms that aid in the production of original artworks. The semester will begin with a series of projects in which students gain familiarity with the norms and practices of open source collaboration, development, and publishing. From there, students will have the opportunity to devise and use an example of open hardware in the creation of an original body of work. Topics include: bootstrapping, hacking, intellectual property, licensure and attribution, speculative fiction, Cyberpunk aesthetics, Afrofuturism, Shanzhai, additive and subtractive fabrication, physical computing, motion control systems, experimental materials, digital distribution, and dissemination.


Studio: Spatial Dynamics is a studio-based inquiry into physical, spatial and temporal phenomena. The study of Spatial Dynamics is rooted in the necessity to consider forces and their effects on structure. Force is the consequence of energy. In Spatial Dynamics the energy and resultant forces are studied in actual motion, stability, and materiality. The structures of physical, spatial and temporal phenomena are studied through additive, subtractive, transformative, iterative, and ephemeral processes both analog and digital. Mediums and materials that are commonly explored and utilized have a broad range of characteristics due to their organic and synthetic sources. Most assignments utilize methods such as preliminary sketches and diagrams in research, planning, and experimental processes. Assignments reference the histories and theories of art and design and include areas of inquiry that extend to disciplines such as the sciences, music, dance, film, and theater.


Building on technologies covered in Digital Design and Fabrication, this studio will explore relationships between digital fabrication, traditional sculptural and craft processes. Students will research and develop approaches to making that blend emerging fabrication technologies with traditional sculptural techniques including woodworking, metalworking, and casting. Students will leverage existing skillsets and departmental resources to both augment and invent methods of fabrication that complement their research and studio interests. The course will explore intermediate / advanced 3d modeling, 3d capture, robotics, and additive/subtractive fabrication techniques using both departmental and campus resources. Through weekly slide presentations, readings and class discussions, students will be introduced to a broad range of artistic approaches, practices and communities merging technology and craft. Rhino 3D will be used as the primary CAD tool and students will need to provide their own laptop with Rhino installed.
