description: Support vector machine (SVM) based multivariate pattern analysis (MVPA) has delivered promising performance in decoding specific task states based on functional magnetic resonance imaging (fMRI) of the human brain. Conventionally, the SVM-MVPA requires careful feature selection/extraction according to expert knowledge. In this study, we propose a deep neural network (DNN) for directly decoding multiple brain task states from fMRI signals of the brain without any burden for feature handcrafts. We trained and tested the DNN classifier using task fMRI data from the Human Connectome Project's S1200 dataset (N=1034). In tests to verify its performance, the proposed classification method identified seven tasks with an average accuracy of 93.7%. We also showed the general applicability of the DNN for transfer learning to small datasets (N=43), a situation encountered in typical neuroscience research. The proposed method achieved an average accuracy of 89.0% and 94.7% on a working memory task and a motor classification task, respectively, higher than the accuracy of 69.2% and 68.6% obtained by the SVM-MVPA. A network visualization analysis showed that the DNN automatically detected features from areas of the brain related to each task. Without incurring the burden of handcrafting the features, the proposed deep decoding method can classify brain task states highly accurately, and is a powerful tool for fMRI researchers.

description: Numerical Renormalization Group simulations have shown that the underscreened spin-1 Kondo impurity model with power-law bath density of states (DOS) $ρ(\w) \propto |\w|^r$ possesses various intermediate-coupling fixed points, including a stable non-Fermi liquid phase. In this paper we discuss the corresponding universal low-energy theories, obtain thermodynamic quantities and critical exponents by renormalization group analysis together with suitable $ε$-expansions, and compare our results with numerical data. Whereas the particle-hole symmetric critical point can be controlled at weak coupling using a simple generalization of the spin-1/2 model, we show that the stable non-Fermi liquid fixed point must be accessed near strong coupling via a mapping onto an effective ferromagnetic $S_\mr{eff}=1/2$ model with singular bath DOS with exponent $r_\mr{eff}=-r<0$. In addition, we consider the particle-hole asymmetric critical fixed point, for which we propose a universal field theory involving the crossing between doublet and triplet levels.

description: The interaction of an expanding Pair-Electromagnetic pulse (PEM pulse) with a shell of baryonic matter surrounding a Black Hole with electromagnetic structure (EMBH) is analyzed for selected values of the baryonic mass at selected distances well outside the dyadosphere of an EMBH. The dyadosphere, the region in which a super critical field exists for the creation of electron-positron pairs, is here considered in the special case of a Reissner-Nordstrom geometry. The interaction of the PEM pulse with the baryonic matter is described using a simplified model of a slab of constant thickness in the laboratory frame (constant-thickness approximation) as well as performing the integration of the general relativistic hydrodynamical equations. The validation of the constant-thickness approximation, already presented in a previous paper Ruffini, et al.(1999) for a PEM pulse in vacuum, is here generalized to the presence of baryonic matter. It is found that for a baryonic shell of mass-energy less than 1% of the total energy of the dyadosphere, the constant-thickness approximation is in excellent agreement with full general relativistic computations. The approximation breaks down for larger values of the baryonic shell mass, however such cases are of less interest for observed Gamma Ray Bursts (GRBs). On the basis of numerical computations of the slab model for PEM pulses, we describe (i) the properties of relativistic evolution of a PEM pulse colliding with a baryonic shell; (ii) the details of the expected emission energy and observed temperature of the associated GRBs for a given value of the EMBH mass; 10^3 solar masses, and for baryonic mass-energies in the range 10^{-8} to 10^{-2} the total energy of the dyadosphere.

description: Noncommutative ${\cal N}=1$ and ${\cal N}=2$ supersymmetric Yang-Mills theories with gauge group U(N) are studied here using the background field method and superspace background covariant D-algebra in perturbation theory. At one loop divergences arise only in the two-point functions. They are logarithmic UV/IR divergences in the planar/nonplanar sectors that play a role dual to each other. We compute the planar and non planar contributions to the three- and four-point functions with vector external lines. We find that the three-point function vanishes, while the four-point function receives contributions both from vector and from chiral matter loops.

Intensiivinen sienten viljely; metsänhoitotekniikat; metsänhoidon työkalu; osterivinokas; pakuri; lakkakääpä (reishi); siitakesieni

description: Metsä on lisäansioiden lähde monille yli 600 tuhannesta yksityisestä metsänomistajasta Suomessa. Läpimitaltaan pienten puiden harvennuksista saatu tuotto on kuitenkin melko matala, vain pari euroa puulta. Sienten aktiivinen viljely metsissä voi lisätä metsän tuottoa selvästi. Sienten viljely lisätulon lähteenä voi tuottaa satoa yhdestä vuodesta jopa kahdeksaan vuoteen (pakuri, Inonotus obliquus) ymppäyksen jälkeen. Lisäksi se on ympäristöystävällinen keino lisätä ruoantuotantoa metsissä. Sen sijaan, että tuotettaisiin ainoastaan puuta raaka-aineeksi, metsä voi myös tuottaa laadukasta ruokaa. Sienten viljelyä elävissä puissa voidaan myös käyttää ekologisena metsänhoidon työkaluna, joka säästää harvennus kuluja. Intensiiviset sienten viljelymenetelmät tuottavat sienisadon joka vuosi, kun taas vähemmän intensiiviset tekniikat tuottavat sadon 5-6 vuoden välein. - For many of the more than 600 thousand private forest owners in Finland, forestry is an additional source of income. However, the income generated from harvesting small-diameter trees during thinning is quite low and amounts to just a couple of euros per tree. Active mushroom cultivation in forests can markedly increase the earnings from forests.

description: Because of the presence of a liquid-gas phase transition in nuclear matter, compact-star matter can present a region of instability against the formation of clusters. We investigate this phase separation in a matter composed of neutrons, protons and electrons, within a Skyrme-Lyon mean-field approach. Matter instability and phase properties are characterized through the study of the free-energy curvature. The effect of beta-equilibrium is also analyzed in detail, and we show that the opacity to neutrinos has an influence on the presence of clusterized matter in finite-temperature proto-neutron stars.

description: Multiple-choice load balancing has been a topic of intense study since the seminal paper of Azar, Broder, Karlin, and Upfal. Questions in this area can be phrased in terms of orientationsof a graph, or more generally a k-uniform random hypergraph. A (d,b)-orientation is an assignment of each edge to d of its vertices, such that no vertex has more than b edges assigned to it. Conditions for the existence of such orientations have been completely documented except for the “extreme” case of (k−1,1)-orientations. We consider this remaining case, and establish: The density threshold below which an orientation exists with high probability, and above which it does not exist with high probability. An algorithm for finding an orientation that runs in linear time with high probability, with explicit polynomial bounds on the failure probability. Previously, no closed-form expression for the threshold was known. The only known algorithms for constructing (k−1,1)-orientations worked for k≤3, and were only shown to haveexpected linear running time.

description: In this work, we analyze the free expansion of Bose-Einstein condensates containing multicharged vortices. The atomic cloud is initially confined in a three-dimensional asymmetric harmonic trap. We apply both approximate variational solutions and numerical simulations of the Gross-Pitaevskii equation. The data obtained provide a way to establish the presence as well as the multiplicity of vortices based only on the properties of the expanded cloud which can be obtained via time-of-flight measurements. In addition, several features such as the evolution of the vortex core size and the asymptotic velocity during free expansion were studied considering the atomic cloud as being released from different harmonic trap configurations.

description: We have observed the Be/X-ray pulsar binary system X Per/4U 0352+30 on 61 occasions spanning an interval of 600 days with the PCA instrument on RXTE. Pulse timing analyses of the 837-s pulsations yield strong evidence for the presence of orbital Doppler delays. We confirm the Doppler delays by using measurements made with the RXTE All-Sky Monitor. We obtain an orbital period of 250 days, a projected semimajor axis of the neutron star of 454 lt-s, a mass function of 1.61 solar masses, and a modest eccentricity of 0.11. We discuss the formation of the system in the context of the standard evolutionary scenario for Be/X-ray binaries with consideration of the possibility that the birth of the neutron star was accompanied by a kick of the type often inferred from the velocity distribution of isolated radio pulsars. The orbital eccentricity just after the supernova explosion was almost certainly virtually the same as at present, because the Be star is much smaller than the orbital separation. We find that the system most likely formed from a pair of massive progenitor stars, and probably involved a quasi-stable and nearly conservative transfer of mass from the primary to the secondary. We find that the He star remnant of the primary most likely had a mass less than 6 solar masses after mass transfer. Finally, we speculate that there may be a substantial population of neutron stars formed with little or no kick.

description: Abstract: "In this paper we deal with the dynamics of material interfaces such as solid-liquid, grain or antiphase boundaries. We concentrate on the situation in which these internal surfaces separate three regions in the material with different physical attributes (e.g. grain boundaries in a polycrystal). The basic two-dimensional model proposes that the motion of an interface ╬│[subscript ij] between regions i and j (i,j = 1,2,3, i [not =] j) is governed by the equation V[subscript ij] = [mu subscript ij] (f[subscript ij]k[subscript ij] + F[subscript ij]). (0.1) Here V[subscript ij], k[subscript ij], [mu subscript ij] and F[subscript ij] denote, respectively, the normal velocity, the curvature, the mobility and the surface tension of the interface and the numbers F[subscript ij] stand for the (constant) difference in bulk energies. At the point where the three phases coexist, local equilibrium requires that the curves meet at prescribed angles. (0.2) In case the material constants f[subscript ij] are small, f[subscript ij] = [bracket over epsilon f subscript ij] and [epsilon] << 1, previous analyses based on the parabolic nature of the equations (0.1) do not provide good qualitative information on the behavior of solutions. In this case it is more appropriate to consider the singular case with f[subscript ij] = 0. It turns out that this problem, (0.1) with f[subscript ij] = 0, admits infinitely many solutions. Here, we show that a unique solution, 'the vanishing surface tension (VST) solution', is selected by letting [epsilon] -> 0. Furthermore, we introduce the concept of weak viscosity solution for the problem with [epsilon] = 0 and show that the VST solution coincides with the unique weak solution. Finally, we give examples showing that, in several cases of physical relevance, the VST solution differs from results proposed previously."

description: We analyze the dynamics of random walks with long-term memory (binary chains with long-range correlations) in the presence of an absorbing boundary. An analytically solvable model is presented, in which a dynamical phase-transition occurs when the correlation strength parameter μreaches a critical value μ_c. For strong positive correlations, μ> μ_c, the survival probability is asymptotically finite, whereas for μ< μ_c it decays as a power-law in time (chain length).

We determine the behaviour of this minimum number for a certain large subset of the $(g,n)$ plane, up to a multiplicative constant. In particular it has been shown that for fixed $n$, this minimum value behaves as $\frac{1}{g}$, proving what Penner speculated in 1991.

Subjects: Fisheries and aquaculture

description: No abstracts are to be cited without prior reference to the author.The edible crab (Cancer pagurus) fisheries of the English Channel form the largest crab fishery in Europe and are of considerable importance to UK, France and the Channel Islands. However, assessments of the resource and fisheries are limited (Bennett, 1976; Latrouite & Morizur, 1988), often relying on equilibrium based methods (e.g. length converted catch curves, Smith, 2006 unpublished). The use of dynamic models has suffered with parameter confounding, and has not often been successful (e.g. ICES, 1998). Although data on the fishery have been collected routinely for many years, their quality is variable and they cannot necessarily be considered reliable. As a result these fisheries were selected for inclusion in POORFISH, an EU funded project, aimed to develop and evaluate systems for assessment and management of data poor stocks. This document describes a Schaefer production model for edible crabs, implemented in a Bayesian estimation framework (Thomas et al., 2006; WinBUGS, 2006) that forms one strand of a case study on edible crabs carried out as part of the POORFISH project. This exercise aims to evaluate whether the Bayesian estimation framework can provide a useful platform for providing routine stock assessments. Although the model has been parameterised as well as possible, given the data or knowledge poor nature of the stock and the fact that this is the first attempt at a Bayesian approach to assessment of this stock, the results cannot be considered as definitive. They should rather be used in the context of evaluating whether the Bayesian approach provides a useful tool for assessment of data poor crab stocks.

Small and damped indications of longitudinal optic excitation modes were observed on the tails of the longitudinal acoustic modes at small momentum transfers, $Q\sim5$ nm$^{-1}$. The measured spectra are in good agreement, in both frequency and linewidth, with {\it ab initio} molecular dynamics (MD) simulations but not classical MD simulations. The observation of these modes at small $Q$ and a good agreement with the simulation permits clear identification of these as collective optic modes with well defined phasing between different ionic motions.

description: We discuss the geometry and topology of the complete, non-compact, Ricci-flat Stenzel metric, on the tangent bundle of S^{n+1}. We obtain explicit results for all the metrics, and show how they can be obtained from first-order equations derivable from a superpotential. We then provide an explicit construction for the harmonic self-dual (p,q)-forms in the middle dimension p+q=(n+1) for the Stenzel metrics in 2(n+1) dimensions. Only the (p,p)-forms are L^2-normalisable, while for (p,q)-forms the degree of divergence grows with |p-q|. We also construct a set of Ricci-flat metrics whose level surfaces are U(1) bundles over a product of N Einstein-Kahler manifolds, and we construct examples of harmonic forms there. As an application, we construct new examples of deformed supersymmetric non-singular M2-branes with such 8-dimensional transverse Ricci-flat spaces. We show explicitly that the fractional D3-branes on the 6-dimensional Stenzel metric found by Klebanov and Strassler is supported by a pure (2,1)-form, and thus it is supersymmetric, while the example of Pando Zayas-Tseytlin is supported by a mixture of (1,2) and (2,1) forms. We comment on the implications for the corresponding dual field theories of our resolved brane solutions.

description: We show the velocity solutions to the convective, skew-symmetric, and rotational Galerkin finite element formulations of the Navier-Stokes equations are identical if Scott-Vogelius elements are used, and thus all three formulations will the same pointwise divergence free solution velocity. A connection is then established between the formulations for grad-div stabilized Taylor-Hood elements: under mild restrictions, the formulations' velocity solutions converge to each other (and to the Scott-Vogelius solution) as the stabilization parameter tends to infinity. Thus the benefits of using Scott-Vogelius elements can be obtained with the less expensive Taylor-Hood elements, and moreover the benefits of all the formulations can be retained if the rotational formulation is used. Numerical examples are provided that confirm the theory.

Subjects: Fisheries and aquaculture

description: No abstracts are to be cited without prior reference to the author.An early fishery closure is a difficult decision in short-lived species; managers delay the decision until they feel very sure about resource depletion but they also want to warn the industry in advance to reduce the disruption. This may jeopardize the management target when this decision is taken too late. To deal with this a management procedure is presented. This was successfully applied to a squid fishery that is managed by fishing effort regulation with a minimum escapement of spawning biomass. The decision rule was to close the fishery if the spawning biomass falls below 10000 tons under the constraint of warning fishing industry with 2 weeks in advance. A spatial operating model was developed using a depletion model, a catch projection model, and a spawning biomass projection model. The uncertainty was estimated during the fishing season by bootstrapping and after the season by Bayesian inference (MCMC). The risk was the probability of leaving less than 10000 tons of spawning biomass. For spatial analysis a graphic interface was developed based on real-time electronic logbook system. Three depletion events were localized; the main one in the southern area and the two other small sequential events in the central-north area. The main area was closed at four and the other areas at three weeks before the normal season ended. The escaping spawning biomass was estimated at 13708 tons and the risk of being below 10000 tons at 0.01. During warning period fishing industry actively participated in monitoring the depletion events and discussing the spatially sequential closure strategy. The warning period gave fishing industry transparency and confidence in the new procedure, so closure decision was much easier.

description: The inverse scattering of a time-harmonic elastic wave by a two-dimensional periodic structure in $R^2$ is investigated. The grating profile is assumed to be a graph given by a piecewise linear function on which the third or fourth kind boundary conditions are satisfied. Via an equivalent variational formulation, existence of quasi-periodic solutions for general Lipschitz grating profiles is proved by applying the Fredholm alternative. However, uniqueness of solution to the direct problem does not hold in general. For the inverse problem, we determine and classify all the unidentifiable grating profiles corresponding to a given incident elastic field, relying on the reflection principle for the Navier equation and the rotational invariance of propagating directions of the total field. Moreover, global uniqueness for the inverse problem is established with a minimal number of incident pressure or shear waves, including the resonance case where a Rayleigh frequency is allowed. The gratings that are unidentifiable by one incident elastic wave provide non-uniqueness examples for appropriately chosen wave number and incident angles.
Quantum squeezing and entanglement in a two-mode Bose-Einstein condensate with time-dependent Josephson-like coupling

description: Dynamical evolution of quantum mechanical squeezing and entanglement in a two-mode Bose-Einstein condensate (TBEC) with an adiabatic, time-varying Raman coupling is studied by finding analytical expressions for these quantities. In particular, we study the entanglement between the atoms in the condensate as well as that between the two modes. The nature of the enhanced quantum correlations in TBEC is clarified by considering squeezing and entanglement both with and without the nonlinear interaction turned on; it is found that entanglement approaching maximal value can be achieved with the nonlinear interactions present. Somewhat counter-intuitively, greater squeezing is found in the absence of nonlinear interactions. This is due to the collapses and revivals of the TBEC quantum state induced by the nonlinear interactions. In addition, results involving the self-trapping phase state of TBEC indicate potential for creating a dynamically stable, macroscopic entangled quantum state which is relatively robust with respect to atom number fluctuations.

description: The measurement of a reaction cross section from a pulse height spectrum is a ubiquitous problem in experimental nuclear physics. In $γ$-ray spectroscopy, this is accomplished frequently by measuring the intensity of full-energy primary transition peaks and correcting the intensities for experimental artifacts, such as detection efficiencies and angular correlations. Implicit in this procedure is the assumption that full-energy peaks do not overlap with any secondary peaks, escape peaks, or environmental backgrounds. However, for complex $γ$-ray cascades, this is often not the case. Furthermore, this technique is difficult to adapt for coincidence spectroscopy, where intensities depend not only on the detection efficiency, but also the detailed decay scheme. We present a method that incorporates the intensities of the entire spectrum (e.g., primary and secondary transition peaks, escape peaks, Compton continua, etc.) into a statistical model, where the transition intensities and branching ratios can be determined using Bayesian statistical inference. This new method provides an elegant solution to the difficulties associated with analyzing coincidence spectra. We describe it in detail and examine its efficacy in the analysis of $^{18}$O(p,$γ$)$^{19}$F and $^{25}$Mg(p,$γ$)$^{26}$Al resonance data. For the $^{18}$O(p,$γ$)$^{19}$F reaction, the measured branching ratios improve upon the literature values, with a factor of 4 reduction in the uncertainties.

description: Three-dimensional boundary recovery is a fundamental problem in mesh generation. In this paper, we propose a practical algorithm for solving this problem. Our algorithm is based on the construction of a it constrained Delaunay tetrahedralization (CDT) for a set of constraints (segments and facets). The algorithm adds additional points (so-called Steiner points) on segments only. The Steiner points are chosen in such a way that the resulting subsegments are Delaunay and their lengths are not unnecessarily short. It is theoretically guaranteed that the facets can be recovered without using Steiner points. The complexity of this algorithm is analyzed. The proposed algorithm has been implemented. Its performance is reported through various application examples.

description: We provide integrated cross sections for quasielastic charged-current neutrino-nucleus scattering. Results evaluated using the phenomenological scaling function extracted from the analysis of experimental $(e,e')$ data are compared with those obtained within the framework of the relativistic impulse approximation. We show that very reasonable agreement is reached when a description of final-state interactions based on the relativistic mean field is included. This is consistent with previous studies of differential cross sections which are in accord with the universality property of the superscaling function.

Three-dimensional surface codes: Transversal gates and fault-tolerant architectures

description: One of the leading quantum computing architectures is based on the two-dimensional (2D) surface code. This code has many advantageous properties such as a high error threshold and a planar layout of physical qubits where each physical qubit need only interact with its nearest neighbours. However, the transversal logical gates available in 2D surface codes are limited. This means that an additional (resource intensive) procedure known as magic state distillation is required to do universal quantum computing with 2D surface codes. Here, we examine three-dimensional (3D) surface codes in the context of quantum computation. We introduce a picture for visualizing 3D surface codes which is useful for analysing stacks of three 3D surface codes. We use this picture to prove that the $CZ$ and $CCZ$ gates are transversal in 3D surface codes. We also generalize the techniques of 2D surface code lattice surgery to 3D surface codes. We combine these results and propose two quantum computing architectures based on 3D surface codes. Magic state distillation is not required in either of our architectures. Finally, we show that a stack of three 3D surface codes can be transformed into a single 3D color code (another type of quantum error-correcting code) using code concatenation.

Measure-independent anomaly of nonlocality

description: We show that any Bell local state, with a hidden nonlocality that can be revealed by local filtering, is more, or equally, entangled than nonlocal states. More precisely, it can be deterministically transformed into a nonlocal state, by local operations and classical communication. For such a state, there is a clear anomaly of nonlocality, for any measures of entanglement and nonlocality. Moreover, we prove that the hidden nonlocality of any bipartite state more, or equally, entangled than nonlocal states, can be revealed by local operations and the sending of two one-bit messages, one in each direction. For some particular states, one bit of communication is even enough.

description: No abstracts are to be cited without prior reference to the author.Stock assessments based on research vessel surveys or other fishery independent sources of information are becoming increasingly important as drivers of fisheries management advice, in Europe and elsewhere. In some cases this approach has arisen as a consequence of stringent management measures which have led to less reliable commercial catch and effort data; in others, the stock trends indicated by fishery-independent data are used as informative counterparts to more traditional assessment methods. An important feature of any survey-based method should be the estimation of the variance (or distribution) of output quantities such as mortality and abundance. There are many ways to estimate these variances. In this paper, we explore the characteristics of five such methods, namely the analytic delta method, residual and data bootstraps, parametric multinomial resampling, and Bayesian methods. We use each approach to analyse the variance and bias properties of linear and nonlinear model fits to simple bivariate data, before considering the implications for a simple separable survey-based stock assessment model (SURBA). We conclude that variance estimators need to be considered carefully for such models, as the incorrect choice can result in misleading fisheries management advice.
An operator-splitting heterogeneous finite element method for population balance equations: Stability and convergence

description: We present a heterogeneous finite element approximation of the solution of a population balance equation, which depends both the physical and internal property coordinates. We employ the operator-splitting method to split the high-dimensional population balance equation into two low-dimensional equations, and discretize the low-dimensional equations separately. In particular, we discretize the physical and internal spaces with the standard Galerkin and Streamline Upwind Petrov Galerkin (SUPG) finite elements, respectively. It is demonstrated that the variational form of the operator-split population balance equation is equivalent to the variational form of the standard equation up to a perturbation term of order $tau^2$ in the backward Euler scheme, where $tau$ is a time step. Further, the stability and error estimates have been derived for the heterogeneous finite element discretization scheme applied to the population balance equation. It is shown that a slightly more regularity, $i.e,$ the mixed partial derivatives of the solution has to be bounded, is necessary for the solution of the population balance equation with the operator-splitting finite element method. Numerical results are presented to demonstrate the accuracy of the numerical scheme.

Dynamics of Effective Gluons

description: Renormalized Hamiltonians for gluons are constructed using a perturbative boost-invariant renormalization group procedure for effective particles in light-front QCD, including terms up to third order. The effective gluons and their Hamiltonians depend on the renormalization group parameter lambda, which defines the width of momentum space form factors that appear in the renormalized Hamiltonian vertices. Third-order corrections to the three-gluon vertex exhibit asymptotic freedom, but the rate of change of the vertex with lambda depends in a finite way on regularization of small-x singularities. This dependence is shown in some examples, and a class of regularizations with two distinct scales in x is found to lead to the Hamiltonian running coupling constant whose dependence on lambda matches the known perturbative result from Lagrangian calculus for the dependence of gluon three-point Green's function on the running momentum scale at large scales. In the Fock space basis of effective gluons with small lambda, the vertex form factors suppress interactions with large kinetic energy changes and thus remove direct couplings of low energy constituents to high energy components in the effective bound state dynamics. This structure is reminiscent of parton and constituent models of hadrons.

description: We present first results from an X-ray study of the Hubble Deep Field North (HDF-N) and its environs obtained using 166 ks of data collected by the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra X-ray Observatory. This is the deepest X-ray observation ever reported, and in the HDF-N itself we detect six X-ray sources down to a 0.5--8 keV flux limit of 4E-16 erg cm^-2 s^-1. Comparing these sources with objects seen in multiwavelength HDF-N studies shows positional coincidences with the extremely red object NICMOS J123651.74 +621221.4, an active galactic nucleus (AGN), three elliptical galaxies, and one nearby spiral galaxy. The X-ray emission from the ellipticals is consistent with that expected from a hot interstellar medium, and the spiral galaxy emission may arise from a `super-Eddington' X-ray binary or ultraluminous supernova remnant. Four of the X-ray sources have been detected at radio wavelengths. We also place X-ray upper limits on AGN candidates found in the HDF-N, and we present the tightest constraints yet on X-ray emission from the SCUBA submillimeter source population. None of the 10 high-significance submillimeter sources reported in the HDF-N and its vicinity is detected with Chandra ACIS. These sources appear to be dominated by star formation or have AGN with Compton-thick tori and little circumnuclear X-ray scattering.
