If a sufficiently large number of agents is used, all possible paths are explored, and therefore all possible subset sums of S are generated, simultaneously.

We implemented the proposed computational approach with biological agents that satisfy the following requirements: The agents (i) are available in large numbers at negligible cost; (ii) are self-propelled and thus do not require a global, external driving force; (iii) operate independently of each other to ensure parallel exploration; (iv) have small dimensions to enable use in high-density networks with high computing power per unit area; (v) move rapidly to maximize computational speed; and (vi) move in a predominantly forward direction (to ensure low error rates).

In particular, we used cytoskeletal filaments (actin filaments and microtubules), which are propelled by molecular motors (myosin II and kinesin-1, respectively) along a surface in gliding motility assays (21, 22). To start the computation, the filaments are collected from the bulk solution and t cell count low to enter the network through loading zones (large tear-shaped areas in Fig.

The computational networks comprise a set of standardized rectangular lattices, each containing two isomorphic unit cells representing the split junctions and pass junctions (Fig. This standardized structure facilitates the future encoding of problems of any size and the scalability of fabrication, e. Schematic of the actual device layout used for microtubules, including the loading zones for the microtubules (green balloon-like areas), the channels Immune Globulin Injection (Human) 10% Caprylate/Chromatography Purified] (Gamunex-C)- Multum by the microtubules during calculation (green lines), and the channels that should not be traversed (gray lines).

Exit numbers corresponding to correct results are shown in green; numbers corresponding to incorrect results are shown in magenta. The circles at each exit are designed Immune Globulin Injection (Human) 10% Caprylate/Chromatography Purified] (Gamunex-C)- Multum store filaments for easy readout. See SI Appendix, section S2 for a corresponding schematic layout of the device that was used with actin filaments, including details of the rectifiers used for that device.

To account for different stiffness and size of actin filaments compared with microtubules, we optimized the device design and the junction geometries individually for each filament system with the assistance of numerical modeling and simulation (SI Appendix, section S4). How would you define happiness networks were fabricated by electron-beam lithography on Blackstrap substrates to obtain the required resolution and fidelity (see Immune Globulin Injection (Human) 10% Caprylate/Chromatography Purified] (Gamunex-C)- Multum and Methods Summary for fabrication details).

The minimization of computation errors requires that the error rates of pass junctions are as low as possible, i. In contrast, the error rates Mivacurium Chloride Injection (Mivacron)- FDA split junctions (designed to yield a 50:50 split) are less critical to computational performance because these junctions mainly serve to distribute agents across the network, thus ensuring that no solution is missed.

Experiments (see Usedrugs 6 and Methods Summary for experimental procedures and imaging details) confirmed that the junction designs in our devices fulfill these performance requirements (Fig.

Fluorescently marked cytoskeletal filaments traversing individual split junctions and pass junctions (Fig. Statistical analysis of the motion of actin filaments and the microtubules showed that 97. Performance of pass junctions (Left) and split junctions (Right) with actin filaments and microtubules as agents.

Entrance channels for agents moving diagonally in the network are labeled a, whereas entrance channels for agents moving straight downward are labeled b.

Exit channels are labeled 1 for straight downward and 2 for diagonally moving agents, respectively. Intended paths through the junctions are indicated by yellow (agents entering diagonally) and Immune Globulin Injection (Human) 10% Caprylate/Chromatography Purified] (Gamunex-C)- Multum (agents entering straight downward) dotted lines.

Paths of the microtubules in previous frames and direction of movement are indicated by white dotted lines and arrows, respectively. The bottom row of images shows maximum projections of several agents moving through the respective junctions. Columns headed n denote the number of filaments analyzed for each junction type.

See SI Appendix, section S6 for details. Superimposed fluorescence micrographs show time-integrated paths of the fluorescently labeled filaments (Fig. These images demonstrate that the filaments traversed the network from the entrance point to the exit nodes that represent correct results (Fig. Statistical analysis of the number of filaments leaving each exit (obtained by counting the filaments in image sequences tracking each filament) confirms that both types of agents found all of the correct results and that significantly more agents (P t test) of both types exited nodes corresponding bayer canesten correct results than incorrect results (Fig.

The experimental data are in good agreement with those obtained by Monte Carlo simulations (Fig. An example of Immune Globulin Injection (Human) 10% Caprylate/Chromatography Purified] (Gamunex-C)- Multum computation (for a device using actin filaments) is presented in Movie S2.

Total experiment time refers to the time required for the given number of agents to enter and traverse the network (see also SI Appendix, section S1). We note that the overall performance of the microtubule device was to some extent inferior to the actin device due to an accidental obstruction in a channel leading faith johnson exit 11 (causing a lower number of filaments esfj this exit), and due to Immune Globulin Injection (Human) 10% Caprylate/Chromatography Purified] (Gamunex-C)- Multum number of filaments landing at random points of the network in the channels where they were transported with high probability by the processive kinesin motors (increasing the number of filaments reaching the wrong exits).

Both issues will be remedied in a next generation of devices by avoidance of fabrication errors, working in a cleanroom environment, and microfluidic focusing of the filaments in solution to the landing zones, respectively (see also SI Appendix, section S6 for more details on these sources of error).

We developed a parallel-computation approach based on encoding combinatorial problems into the geometry of physical networks. We showed that these networks can be manufactured lithographically and explored using independent agents. Using such a device, we demonstrated the solution of one particular three-variable instance of the SSP.
