description: We present an approach based on the dynamical mean field theory which is able to give the excitation spectrum of a triply degenerate Hubbard model with a Hund's exchange invariant under spin rotation. The lattice problem can be mapped onto a local Anderson model containing 64 local eigenstates. This local problem is solved by a generalized non-crossing approximation. The influence of Hund's coupling J is examined in detail for metallic states close to the metal insulator transition. The band-filling is shown to play a crucial role concerning the effect of J on the low energy dynamics.

description: In 1990, Australia and New Zealand were ranked around 25th and 35th in terms of GNP per capita, having been the highest-income countries in the world one hundred years earlier. The poor performance over that long period contrasts markedly with that of the past 15 years, when these two economies out-performed most other high-income countries. This difference in growth performance is due to major economic policy reforms during the past two to three decades. We provide new evidence on the extent of governmental distortions to agricultural incentives in particular in the two economies since the late 1940s, both directly and indirectly (and negatively) via manufacturing protection.

description: Nitrogen levels in water resources in the Waikato region are increasing, mainly as a result of non-point source pollution from agricultural activities. Non-point pollution management is a complex issue requiring sufficient information and appropriate institutions. This paper considers the environmental policy literature and analyse how institutions, contract design, and monitoring and transaction costs in the presence of farm heterogeneity encourage optimal abatement. The analysis identifies the key institutional issues to be addressed in the design of appropriate policy measures to address water quality in Waikato river sub-catchment.

description: It is generally held that >100 TeV emission from astrophysical objects unambiguously demonstrates the presence of PeV protons or nuclei, due to the unavoidable Klein-Nishina suppression of inverse Compton emission from electrons. However, in the presence of inverse Compton dominated cooling, hard high-energy electron spectra are possible. We show that the environmental requirements for such spectra can naturally be met in spiral arms, and in particular in regions of enhanced star formation activity, the natural locations for the most promising electron accelerators: powerful young pulsars. Our scenario suggests a population of hard ultra-high energy sources is likely to be revealed in future searches, and may also provide a natural explanation for the 100 TeV sources recently reported by HAWC.

Sylvester-t' Hooft generators of sl(n) and sl(n|n), and relations between them

subject: 17A70; 17B01

description: Among the simple finite dimensional Lie algebras, only sl(n) possesses two automorphisms of finite order which have no common nonzero eigenvector with eigenvalue one. It turns out that these automorphisms are inner and form a pair of generators that allow one to generate all of sl(n) under bracketing. It seems that Sylvester was the first to mention these generators, but he used them as generators of the associative algebra of all n times n matrices Mat(n). These generators appear in the description of elliptic solutions of the classical Yang-Baxter equation, orthogonal decompositions of Lie algebras, 't Hooft's work on confinement operators in QCD, and various other instances. Here I give an algorithm which both generates sl(n) and explicitly describes a set of defining relations. For simple (up to center) Lie superalgebras, analogs of Sylvester generators exist only for sl(n|n). The relations for this case are also computed.

description: Dry land salinisation is a significant cause of land and water degradation in Australia. Changing land use from annual to perennial crops has been widely proposed as a means to reduce land degradation and increase the productivity of saline land. However, in many areas annual crops are financially more attractive than perennial crops. Increases in perennial crops might also reduce local stream flows with adverse effects on in-stream values. As such salinity control is likely to involve significant tradeoffs between public and private costs and benefits. This paper considers the impact of planting differing areas of pastoral and woody perennials on farm profitability (P), and water (W) and salt (S) exports from the Little River catchment in New South Wales (NSW), Australia. The analysis uses two linear programming (LP) models. The first model represents a mixed crop and sheep system and the outputs of this model are integrated to provide inputs to a second catchment level model. The structure of the LP models is described and an analysis of the potential for perennials to assist in salinity management is presented. The implications of the analysis for farm systems and catchment scale changes in land use are considered. The study highlighted the importance of targeting management decisions to individual sub-catchments and of using relatively detailed farm level models as part of a catchment level study. The potential for perennials to contribute to profitable and robust farm systems and to reduce degradation to land from salt scalds and to streams arising with elevated discharge and wash-off of salt is demonstrated.

The independence of the operator basis regarding the equation of motion, integration by parts and flavor relations, is guaranteed by our algorithm, whose validity for the LEFT with massive fermions involved is proved by a generalization of the amplitude-operator correspondence. At dimension 8 and 9, we list the 35058 (756) and 704584 (3686) operators for three (one) generations of fermions categorized by their baryon and lepton number violations $(ΔB, ΔL)$, as these operators are of most phenomenological relevance.

description: The variety of noise sources typical of the solid state represents the main limitation toward the realization of controllable and reliable quantum nanocircuits, as those allowing quantum computation. Such ``structured environments'' are characterized by a non-monotonous noise spectrum sometimes showing resonances at selected frequencies. Here we focus on a prototype structured environment model: a two-state impurity linearly coupled to a dissipative harmonic bath. We identify the time scale separating Gaussian and non-Gaussian dynamical regimes of the Spin-Boson impurity. By using a path-integral approach we show that a qubit interacting with such a structured bath may probe the variety of environmental dynamical regimes.

description: We present the public python package munuSSM that can be used for phenomenological studies in the context of the $μ$-from-$ν$ Supersymmetric Standard Model ($μν$SSM). The code incorporates the radiative corrections to the neutral scalar potential at the full one-loop level. Sizable higher-order corrections, required for an accurate prediction of the SM-like Higgs-boson mass, can be consistently included via an automated link to the public code FeynHiggs. In addition, a calculation of effective couplings and branching ratios of the neutral and charged Higgs bosons is implemented. This provides the required ingredients to check a benchmark point against collider constraints from searches for additional Higgs bosons via an interface to the public code HiggsBounds. At the same time, the signal rates of the SM-like Higgs boson can be tested applying the experimental results implemented in the public code HiggsSignals. The python package is constructed in a flexible and modular way, such that it provides a simple framework that can be extended by the user with further calculations of observables and constraints on the model parameters.

description: Ninety years ago, in November 1929, the Jesuit Fathers of the Pontifical Biblical Institute started their excavations at the site of Teleilat Ghassul on the eastern bank of the Jordan river, just north of the Dead Sea. If the initial impetus was the search for Sodom and Gomorrah, part of contemporary debates among scholars on their location, the expedition uncovered what remains one of the major sites for the Chalcolithic. Over several seasons of excavation (1929-1938, 1959-60), the expedition left a legacy of archaeological material, now mostly in the collection of the Museum of the Pontifical Biblical Institute in Jerusalem, as well as significant archival material: plans and sections, glass plate negative and photo albums, pottery registration cards, finds registers as well as excavation diaries, providing interesting insights into their developing excavations methods and the result achieved.

description: We studied the optical afterglows of the 24 pre-Swift Gamma-Ray Bursts with known spectroscopic redshift and published estimates of the optical extinction in the source frame. We find an unexpected clustering of the optical afterglow luminosities measured 12 hours (source frame time) after the trigger. For 21 out of 24 bursts, the distribution of the optical luminosities is narrower than the distribution of the X-ray luminosities, and even narrower than the distribution of the ratio between the monochromatic optical luminosities and the total isotropic emitted prompt energy. Three bursts stand apart from the distribution of the other sources, being underluminous by a factor ~15. We compare this result with the somewhat analogous result concerning the luminosity of the X-ray afterglows studied by Gendre & Boer. For all our GRBs we construct the optical to X-ray spectral energy distribution. For all but a minority of them, the optical and the X-ray emissions are consistent with being produced by the same radiation process. We discuss our results in the framework of the "standard" external shock synchrotron model. Finally, we consider the behavior of the first GRBs of known redshifts detected by Swift. We find that these Swift GRBs entirely confirm our findings.

description: Randomized experiments, or "A/B" tests, remain the gold standard for evaluating the causal effect of a policy intervention or product change. However, experimental settings, such as social networks, where users are interacting and influencing one another, may violate conventional assumptions of no interference for credible causal inference. Existing solutions to the network setting include accounting for the fraction or count of treated neighbors in a user's network, yet most current methods do not account for the local network structure beyond simply counting the number of neighbors. Our study provides an approach that accounts for both the local structure in a user's social network via motifs as well as the treatment assignment conditions of neighbors. We propose a two-part approach. We first introduce and employ "causal network motifs", which are network motifs that characterize the assignment conditions in local ego networks; and then we propose a tree-based algorithm for identifying different network interference conditions and estimating their average potential outcomes. Our approach can account for social network theories, such as structural diversity and echo chambers, and also can help specify network interference conditions that are suitable to each experiment. We test our method on a synthetic network setting and on a real-world experiment on a large-scale network, which highlight how accounting for local structures can better account for different interference patterns in networks.

description: Mandatory inspection and maintenance programs require on-road vehicles to be tested regularly and repaired if they are not in compliance with air emission regulations. The purpose of this paper is to estimate the abatement cost function for a representative inspection and maintenance program. We do this by constructing a model of the statistical process that leads to noncompliance, parameterizing the model, and then by simulating the total abatement cost function. Our model predicts that the marginal abatement cost for a major representative program is so high that even a small reduction in the abatement target leads to substantial social cost savings. In addition, even for quite high levels of the abatement target, the optimal minimum testing age is substantially higher and the frequency of testing is much lower than is common in many jurisdictions.
Financing investment with external funds
Creators: name: Moyen, Nathalie
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents various dynamic models of corporate decisions to address two main issues: investment distortions caused by debt financing and cash flow sensitivities. In the first chapter, four measures of investment distortion are computed. First, the effect of financing frictions is examined. The tax benefit of debt induces firms to increase their debt capacity and to invest beyond the first-best level on average. The cost of this investment distortion outweighs the tax benefit of debt. Second, Myers's (1977) debt overhang problem is examined in a dynamic framework. Debt overhang obtains on average, but not in low technology states. Third, there is no debt overhang problem in all technology states when debt is optimally put in place prior to the investment decision. Finally, the cost of choosing investment after the debt policy is examined. Equity claimants lose value by choosing to invest after their debt is optimally put in place because they do not consider the interaction between their investment choice and the debt financing conditions. The second chapter explores the impact of financial constraints on firms' cash flow sensitivities. In contrast to Fazzari, Hubbard, and Petersen (1988), cash flow sensitivities are found to be larger, rather than smaller, for unconstrained firms than for constrained firms. Then, why is investment sensitive to cash flow? In the two models examined in the second chapter, the underlying source of investment opportunities is highly correlated with cash flows. Investment may be sensitive to cash flow fluctuations simply because cash flows proxy for investment opportunities. This leaves two important questions. Can this chapter suggest a better measure of investment opportunities than Tobin's Q? Not a single measure for both the unconstrained and constrained firm models. Can this chapter suggest an easily observable measure of financial constraint? Yes: large and volatile dividend-to-income ratios.

description: We consider stochastic reaction-diffusion equations on a finite network represented by a finite graph. On each edge in the graph a multiplicative cylindrical Gaussian noise driven reaction-diffusion equation is given supplemented by a dynamic Kirchhoff-type law perturbed by multiplicative scalar Gaussian noise in the vertices. The reaction term on each edge is assumed to be an odd degree polynomial, not necessarily of the same degree on each edge, with possibly stochastic coefficients and negative leading term. We utilize the semigroup approach for stochastic evolution equations in Banach spaces to obtain existence and uniqueness of solutions with sample paths in the space of continuous functions on the graph. In order to do so we generalize existing results on abstract stochastic reaction-diffusion equations in Banach spaces.

PRIORITY BASED CLUSTER MESSAGE SCHEDULING FOR SINGLEHOP WDM NETWORKS

Subjects: subject: 100503 Computer Communications Networks
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: Network performance for a single-hop WDM network deteriorates due to packet collisions that occur in both source and destination nodes. These collisions can also occur in both the control and data channels as in the case where reservation techniques are adopted. In order to reduce these collisions and maximize bandwidth utilization, we present in this paper an on-line scheduling method that can result in collision free communication and achieve real time operation in high-speed multiprocessor systems. The method we propose can be easily adapted to other network types employing optical interconnects. We conduct a throughput analysis of our scheme using methods from discrete-time queueing systems and use computer simulation results to compare the different variations of our scheduling algorithm. Our method efficiently utilizes the enormous bandwidth potential Optical Interconnects and Wavelength Division Multiplexing (WDM) techniques provide in computer network communication. This method is unique because it allows the transmission schedule to be staggered in time and space with provision for on-line packet arrivals and mixed packets types (unicast, multicast and broadcast). It is topology independent. Access to each data channel is controlled by a priority based cluster scheme that optimizes bandwidth utilization while minimizing packet delay. The basic idea of our proposed scheduling method is to show that the data packet sequencing has a profound effect on network traffic performance and, surprisingly, it has not received much attention. Accordingly, our results show that efficient message ordering in the data scheduling stage of the Routing and Wavelength Allocation (RWA) process, can better effectively utilize the enormous bandwidth potential available in optics. These results consequently lead to a remarkable improved throughput performance and lower average packet delay.

description: The increase in greenhouse gas emissions and degradation of water quality and quantity in waterways due to dairy farming in New Zealand have become of growing concern. Compared to traditional sheep and beef cattle farming, dairy farming is more input intensive and more likely to cause such environmental damage. Our study uses choice modeling to explore New Zealanders' willingness to pay for sustainable dairy and sheep/beef cattle farming. We investigate respondents' level of awareness of the environmental degradation caused by dairy farming and their willingness to make trade-offs between economic growth and improvements in the level of ecosystem services associated with pastoral farming.

Here, we show that the existing methods to deal with liquid-wall interactions using multicomponent Lattice Boltzmann are accurate when the wall is aligned with the main axes of the lattice but fail otherwise. To solve this problem, we extend a strategy previously developed for multiphase models. As an example, we study the coalescence of two droplets on a curved surface in two dimensions. The strategy proposed here is of special relevance for binary flows in complex geometries.

description: A recently introduced particle-based model for fluid flow, called Stochastic Rotation Dynamics, can be made Galilean invariant by introducing a random shift of the computational grid before collisions. In this paper, it is shown how the Green-Kubo relations derived previously can be resummed to obtain exact expressions for the collisional contributions to the transport coefficients. It is also shown that the collisional contribution to the microscopic stress tensor is not symmetric, and that this leads to an additional viscosity. The resulting identification of the transport coefficients for the hydrodynamic modes is discussed in detail, and it is shown that this does not impose restrictions on the applicability of the model. The collisional contribution to the thermal conductivity, which becomes important for small mean free path and small average particle number per cell, is also derived.

description: In this paper, we study the triple top quark production at the future high-energy proton-proton colliders to probe the four-fermion interactions involving three top quarks. We employ the Standard Model Effective Field Theory (SMEFT) to find the upper limits at $95\%$ CL on the Wilson coefficients of these kinds of four-fermion operators. We consider a detailed analysis with a unique signal signature of two same-sign leptons. A full simulation chain includes all the relevant backgrounds, realistic detector simulations and a cut-based technique are taken into account. This study is presented for the HE-LHC working at the center of mass energy of 27 TeV with 15~ab$^{-1}$ and FCC-hh working at the center of mass energy of 100 TeV with 30~ab$^{-1}$. We show that the future high-energy proton-proton colliders could reach an impressive sensitivity to four-fermion contact interactions involving three top quarks.

description: Primordial density perturbations in the radiation-dominated era of the early Universe are expected to generate stochastic gravitational waves (GWs) due to nonlinear mode coupling. In this \emph{Letter}, we report on a search for such a stochastic GW background in the data of the two LIGO detectors during their second observing run (O2). We focus on the primordial perturbations in the range of comoving wavenumbers $10^{16}-10^{18}~{\rm Mpc}^{-1}$ for which the stochastic background falls within the detectors' sensitivity band. We do not find any conclusive evidence of this stochastic signal in the data, and thus place the very first GW-based constraints on the amplitude of the power spectrum at these scales. We assume a lognormal shape for the power spectrum and Gaussian statistics for the primordial perturbations, and vary the width of the power spectrum to cover both narrow and broad spectra. Derived upper limits ($95\%$) on the amplitude of the power spectrum are $0.01-0.1$. As a byproduct, we are able to infer upper limits on the fraction of the Universe's mass in ultralight primordial black holes ($M_\mathrm{PBH} \simeq 10^{-20}-10^{-19}M_{\odot}$) at their formation time to be $\lesssim 10^{-25}$.

description: A new multi-channel, CDMA (Code Division Multiple Access) (or FDMA (Frequency Division Multiple Access)) and TDMA (Time Division Multiple Access) combined, contention free MAC (Medium Access Control), termed the Sequenced Neighbor Double Reservation (SNDR), is presented for mobile ad hoc networks. The SNDR uses the receiver-based data transmission strategy, based on which two methods are proposed. One is contention-based and the other is contention-free. In this paper, we put emphasis on the contention-free type (SNDR). On the other hand, the contention-based MAC, which needs further research, is also briefly discussed. The SNDR does not need any handshake process (such as Request to Sendclear to Send (RTSKTS) handshake) or any carrier sensing technology. It uses the neighbor sequenced method to avoid contentions and the double reservation method to improve the total throughput of ad hoc networks. No hidden or exposed terminal problem will exist in the SNDR. No collision will occur and no time slot will be wasted in the SNDR MAC frame. The protocol can be efficiently applied to the multichannel ad hoc networks. The performance of the SNDR is analyzed carefully. Some future work and applications are also discussed.

description: It is shown that the two-gap approximation is applicable for describing the $dV/dI(V)$ spectra of LuNi$_{2}$B$_{2}$C-Ag point contacts in a wide interval of temperatures. The values and the temperature dependences of the large and the small gaps in the $ab$ plane and in the $c$ direction were estimated using the generalized BTK model and the equations of Beloborodko. In the BCS extrapolation the critical temperature of the small gap is 10 $K$ in the $ab$ plane and 14.5 $K$ in the $c$ direction. The absolute values of the gaps are $Δ_0^{ab}=2.16$ $meV$ and $Δ_0^c=1.94$ $meV$. For the large gaps the critical temperature coincides with the bulk $T_c$, $T_c^{bulk}=16.8$ $K$, and their absolute values are very close, being about 3 $meV$ in both orientations. In the $c$ direction the contributions to the conductivity from the small and the large gaps remain practically identical up to $10 ÷11$ $K$. In the $ab$ plane the contribution from the small gap is much smaller and decreases rapidly as a temperature rises.

During the past few years, many routing protocols have been proposed for this particular network environment. While in wired and optical networks, multi-protocol label switching (MPLS) has clearly shown its advantages in routing and switching such as flexibility, high efficiency, scalability, and low cost. But MPLS is complex and does not consider the mobility issue for wireless networks, especially for ad hoc networks. This paper migrates the label concept into the ad hoc network and provide a framework for the efficient label routing protocol(LRP) in such a network. The MAC layer is also optimized with LRP for shorter delay, power saving, and higher efficiency. With this cross-layer routing protocol, network performance such as throughput, delay, and QoS assignment can be improved significantly.

description: We obtain a compact analytical solution for the nonlinear equation for the nuclear spin dynamics in the central spin box model in the limit of many nuclear spins. The total nuclear spin component along the external magnetic field is conserved and the two perpendicular components precess or oscillate depending on the electron spin polarization, with the frequency, determined by the nuclear spin polarization. As applications of our solution, we calculate the nuclear spin noise spectrum and describe the effects of nuclear spin squeezing and many body entanglement in the absence of a system excitation.

description: We investigate collective multipole excitations for closed shell nuclei from 16O to 208Pb using correlated realistic nucleon -nucleon interactions in the framework of the random phase approximation (RPA). The dominant short-range central and tensor correlations a re treated explicitly within the Unitary Correlation Operator Method (UCOM), which provides a phase-shift equivalent correlated interaction V_UCOM adapted to simple uncorrelated Hilbert spaces. The same unitary transformation that defines the correlated interaction is used to derive correlated transition operators. Using V_UCOM we solve the Hartree-Fock problem and employ the single-particle state s as starting point for the RPA. By construction, the UCOM-RPA is fully self-consistent, i.e. the same correlated nucleon-nucleon interact ion is used in calculations of the HF ground state and in the residual RPA interaction. Consequently, the spurious state associated with t he center-of-mass motion is properly removed and the sum-rules are exhausted within +-3%. The UCOM-RPA scheme results in a collective character of giant monopole, dipole, and quadrupole resonances in closed-shell nuclei across the nuclear chart. For the isoscalar giant monopole resonance, the resonance energies are in agreement with experiment hinting at a reasonable compressibility. However, in the 1- and 2+ channels the resonance energies are overestimated due to missing long-range correlations and three-body contributions.

description: We answer the question what properties a collection $\mathcal{F}$ of three-valued functions on a set $U$ must fulfill so that there exists a quasiorder $\leq$ on $U$ such that the rough sets determined by $\leq$ coincide with the core--support pairs of the functions in $\mathcal{F}$. Applying this characterization, we give a new representation of rough sets determined by equivalences in terms of three-valued Łukasiewicz algebras of three-valued functions.

description: Ever since Adleman solved the Hamilton Path problem using a combinatorial molecular method, many other hard computational problems have been investigated with the proposed DNA computing. However, simple computer operations, such as the Boolean and basic arithmetic operations, have not been addressed much. We propose a new method for these operations based on insertion, deletion and substitution. The great aspect of this method is that the total number of biological manipulation steps needed is linear and the output result can be easily used as the input for further operations.

Characterization of protein tyrosine phosphatase E
Creators: name: Melhado, Ian Granville
Publisher: name: University of British Columbia
Year: 2009

description: Protein tyrosine phosphatases have been shown to play an important role in immune cell regulation. This study focused upon identifying PTPases that were regulated during inflammation. Using PCR mediated differential hybridization PTPε was identified as a candidate PTPase mRNA upregulated by pro-inflammatory stimuli. Northern blotting analysis confirmed that the message for this PTPase was induced by a limited number of stimuli in cells of the monocyte/macrophage lineage. With the development of highly specific polyclonal antibodies, monocyte/macrophage derived PTPs was observed as a 72/74 kDa doublet. p72/74PTPε was found to possess PTPase activity in vitro, predominantly within the cytosol, and its expression was observed to be regulated during cellular differentiation. Further characterization of PTPε indicated that the PTPase was phosphorylated and tyrosine phosphorylation could be induced in vivo. Tyrosine phosphorylation was found to induce the association of the small adapter protein GRB2 with PTPε in pervanadate treated cells. These observations and others pointed to a novel isoform of the previously described transmembrane PTPε PTPase. An in vitro analysis of recombinant PTPε was undertaken to characterize the PTPase activity of the enzyme. This analysis revealed that the PTPase had a pH optimum of 5.6. PTPε exhibited some substrate specificity especially when compared to other recombinant PTPases such as CD45 and PTPα. From the preceding analysis and the fact that the closely related PTPα appears to show specificity for pp60c'src, the src family kinases were the signaling proteins initially investigated as potential in vivo substrates of PTPε. By utilizing cDNAs encoding both transmembrane and non-transmembrane isforms of PTPε, PTPases were introduced into mammalian cells. In the case of transmembrane PTPε, various mutants were characterized in vivo. These studies revealed that plOO/11OPTPε is a highly glycosylated membrane protein, found predominantly at cell-cell junctions. While plOO/11OPTPε was capable of associating with and modulating the phosphotyrosine content and kinase activity of the src family kinase members pp60c" s r c and pp59*" p72/74PTPε was not. This phenomenon may be explained by the observation that the localization of p72/74PTPε was to the nucleus and not the plasma membrane where src family kinases are found. Finally, the PTPε homologue was reported to contain a SH3 binding site, however, this site was not conserved in PTPε. A proline residue was introduced at position Fl 12 and resulted in the reconstitution of an SH3 domain-binding site thus turning PTPε into a PTPα like molecule. PTPεF112P exhibited altered substrate specificity showing increased activity towards src family kinases and reduced activity towards the in vivo substrate Crkll.

A Surface-Based DNA Algorithm for the Expansion of Symbolic Determinants

subject: FOS: Mathematics

description: In the past few years since Adleman’s pioneering work on solving the HPP(Hamiltonian Path Problem) with a DNA-based computer [1], many algorithms have been designed on solving NP problems. Most of them are in the solution bases and need some error correction or tolerance technique in order to get good and correct results [3] [7] [9] [11] [21] [22]. The advantage of surface-based DNA computing technique, with very low error rate, has been shown many times [12] [18] [17] [20] over the solution based DNA computing, but this technique has not been widely used in the DNA computer algorithms design. This is mainly due to the restriction of the surface-based technique comparing with those methods using the DNA strands in solutions. In this paper, we introduce a surface-based DNA computing algorithm for solving a hard computation problem: expansion of symbolic determinants given their patterns of zero entries. This problem is well-known for its exponential difficulty. It is even more difficult than evaluating determinants whose entries are merely numerical [15]. We will show how this problem can be solved with the low error rate surface-based DNA computer using our naive algorithm.
