description: Motivated by the rencent LHC data on the lepton-flavor violating (LFV) decays $h\to \ell_1 \ell_2$ and $B_{s,d}\to \ell_1 \ell_2$, we study the Higgs-mediated flavor-changing neutral current (FCNC) interactions in the effective field theory (EFT) approach without and with the minimal flavor violation (MFV) hypothesis, and concentrate on the later. After considering the $B$ and $K$ physics data, the various LFV processes, and the LHC Higgs data, severe constraints on the Higgs FCNC couplings are derived, which are dominated by the LHC Higgs data, the $B_s - \bar B_s$ mixing, and the $μ\to e γ$ decay. In the general case and the MFV framework, allowed ranges of various observables are obtained, such as $\mathcal B (B_s\to \ell_1 \ell_2)$, $\mathcal B (h\to \ell_1 \ell_2)$, $\mathcal B (h\to q_1 q_2)$, and the branching ratio of $μ\to e$ conversion in Al. Future prospects of searching for the Higgs FCNC interactions at the low-energy experiments and the LHC are discussed.

description: We consider nonlinear half-wave equations with focusing power-type nonlinearity $$ i \pt_t u = \sqrt{-Δ} \, u - |u|^{p-1} u, \quad \mbox{with $(t,x) \in \R \times \R^d$} $$ with exponents $1 < p < \infty$ for $d=1$ and $1 < p < (d+1)/(d-1)$ for $d \geq 2$. We study traveling solitary waves of the form $$ u(t,x) = e^{iωt} Q_v(x-vt) $$ with frequency $ω\in \R$, velocity $v \in \R^d$, and some finite-energy profile $Q_v \in H^{1/2}(\R^d)$, $Q_v \not \equiv 0$. We prove that traveling solitary waves for speeds $|v| \geq 1$ do not exist. Furthermore, we generalize the non-existence result to the square root Klein--Gordon operator $\sqrt{-\DD+m^2}$ and other nonlinearities. As a second main result, we show that small data scattering fails to hold for the focusing half-wave equation in any space dimension. The proof is based on the existence and properties of traveling solitary waves for speeds $|v| < 1$. Finally, we discuss the energy-critical case when $p=(d+1)/(d-1)$ in dimensions $d \geq 2$.

description: We study the production and equilibration of the gluon-minijet plasma expected to be formed in the central region of ultrarelativistic heavy-ion collisions at the BNL-RHIC and the CERN-LHC by solving a self-consistent relativistic transport equation. We compute the minijet production within perturbative QCD. Subsequent collisions among the semi-hard partons are treated by considering the elastic gg -> gg processes with screening of the long wavelength modes taken into account. We determine the time $τ_{eq}$ where close to ideal hydrodynamic flow sets in, and find rather similar numbers for central heavy-ion collisions at BNL-RHIC and CERN-LHC energies. The number densities, energy densities and temperatures of the minijet plasma are found to be different at RHIC and LHC, e.g. $T(τ_{eq})\sim220$ MeV and 380 MeV, respectively.

description: Using circularly polarized light is an alternative to electronic ways for spin injection into materials. Spins are injected at a point of the light illumination, and then diffuse and spread radially due to the in-plane gradient of the spin density. This diffusion is converted into a circular charge current by the inverse spin Hall effect (ISHE). With shining the circularly polarized light at asymmetric parts of the sample, such as near edges, we detected this current as a helicity-dependent component in the photocurrent. We present a model for this ISHE based on the experimental results and the finite-element-method (FEM) simulation of the potential distribution induced by spin injection. Our model shows that the ISHE photocurrent generates an electric dipole at the edge of the sample, causing the measured charge current. The asymmetric light-illumination shown here is a simple way to inject and manipulate spins, opening up a door for novel spintronic devices.

job-to-job transitions
Nominal wage rigidity
on-the-job search

description: We consider a Burdett/Mortensen style wage posting model with aggregate shocks. We analyze the equilibrium under two alternative assumptions on wage setting in ongoing jobs: either fully flexible or downwardly rigid. In the model firms optimally pay only retention premiums. The equilibrium is characterized by a Taylor expansion. The model yields two simultaneous relations for wages and quits, of which the parameters are simple functions of three empirically observable arrival rates of: (i) jobs, (ii) lay offs, and (iii) aggregate shocks. Hence, there are overidentifying restrictions, which are supported remarkably well by the data. We find strong evidence for wage downward rigidity and inefficiently low job-to-job transitions during the downturn. Furthermore, we find evidence that firms pay only retention premiums, not hiring premiums. A model with wage rigidity in ongoing jobs and OJS is therefore a useful benchmark for a wage equation in macro models. Under rigidity, job-to-job transitions are in efficiently low during the downturn.

description: SUMOylation is a post-translational modification of proteins that regulates these proteins' localization, turnover or function. Aberrant SUMOylation is frequently found in cancers but its origin remains elusive. Using a genome-wide transposon mutagenesis screen in a MYC-driven B-cell lymphoma model, we here identify the SUMO isopeptidase (or deconjugase) SENP6 as a tumor suppressor that links unrestricted SUMOylation to tumor development and progression. Notably, SENP6 is recurrently deleted in human lymphomas and SENP6 deficiency results in unrestricted SUMOylation. Mechanistically, SENP6 loss triggers release of DNA repair- and genome maintenance-associated protein complexes from chromatin thereby impairing DNA repair in response to DNA damages and ultimately promoting genomic instability. In line with this hypothesis, SENP6 deficiency drives synthetic lethality to Poly-ADP-Ribose-Polymerase (PARP) inhibition. Together, our results link SENP6 loss to defective genome maintenance and reveal the potential therapeutic application of PARP inhibitors in B-cell lymphoma. SUMOylation is a post-translational modification that has been shown to be altered in cancer. Here, the authors show that loss of the SUMO isopeptidase SENP6 leads to unrestricted SUMOylation and genomic instability promoting lymphomagenesis and generating vulnerability to PARP inhibition.
Causes and Effects of Private Property Rights Security

Private Property Rights Security

Con-straints on the Executive

description: Private property rights security is currently seen as central to explaining cross-country differences in economic development. Variation in private property rights security itself is perceived to be best explained by differences in the degree to which the political system is able to constrain the despotic power of state executives. I reassess the existing evidence for these two hypotheses and find that: (1) higher levels and significant changes in private property rights security and constraints on the executive are not correlated with higher levels of income and (changes in) growth rates; (2) the commonly used instrument for constraints on the executive and private property rights security - the natural log of European settler mortality - is invalid because it is associated with current levels of income besides its effect through private property rights security and constraints on the executive; and (3) the regularly cited Korean case is in fact evidence against these hypotheses. I provide explanations for these findings and call for a rethinking of which type of institutions and policies are decisive for growth.

description: Sericomyrmex wheeleri pakeelai, ssp. nov. (Fig. 9)
Worker: Length 3.4-4.2 mm. - Head, excluding mandibles and occipital spines, as long as broad, impressed on posterior border. Occipital spines long and blunt, a little logger than the diameter of the eyes. Short, blunt lateral spines above eyes. Antennal scrobes distinct. Antennal scapes extending to apices of occipital spines, about twice as long distally as proximally. Terminal joint of funiculus distinctly shorter than joints 7-9 and but little longer than joints 2-4. Thorax in profile as illustrated (Fig. 9). Basal face of epinotum with more distinct and even ridges and with lower epinotal spines than in typical wheeleri. Gaster with lateral ridges.
Pilosity more abundant and appressed than in typical wheeleri. In addition to the reclinate coarse hairs appearing black basally and gray distally, there are interspersed numerous finer hairs of pale yellowish color. These with a grayish bloom, obscure the integument more than in typical wheeleri. - Pale ferruginous.
Described from a colony taken by myself June 23, 1936, by the Oko River, a tributary of the Cuyuni River, British Guiana. The nest entrance was in the form of a turret, built against a steep slope, whose one side was 45 mm. high and whose opposite side was flush with the slope. The nest structure, consisting of 5 chambers, containing pendant.fungus gardens, and the beginning of a sixth will be described in a subsequent paper.
This form differs from typical wheeleri chiefly in shorter terminal joint of funiculus, more abundant pilosity, color and in the characters of thorax and pedicel shown in the illustrations.
It is dedicated to the Indian hunter, Pakeela, who never failed in bringing back an abundance of game to the camp and who often assisted me in my studies.

firm level growth

description: The purpose of this paper is to revisit an intriguing finding. Although over the last few decades leading up to the financial crisis there was a marked reduction in the volatility of aggregate output and inflation, there appears to have been a corresponding increase in the sales volatility of individual firms. Here we argue that a significant reason for this apparent increase in firm level volatility was an increase in churning of firm activity through the acquisition and disposal of businesses. This created an increase in observed negative covariances between firms, so even if the volatility of underlying organic growth has also fallen, observed volatility has risen
A Theoretical Reappraisal of Branching Ratios and CP Asymmetries in the Decays $B \to (X_d,X_s) \ell^+ \ell^-$ and Determination of the CKM Parameters

description: We present a theoretical reappraisal of the branching ratios and CP asymmetries for the decays $ B \to X_q \ell^+ \ell^-$, with $q=d,s$, taking into account current theoretical uncertainties in the description of the inclusive decay amplitudes from the long-distance contributions, an improved treatment of the renormalization scale dependence, and other parametric dependencies. Concentrating on the partial branching ratios $Δ{\cal B}(B \to X_q \ell^+ \ell^-)$, integrated over the invariant dilepton mass region $1 {GeV}^2 \leq s \leq 6 {GeV}^2$, we calculate theoretical precision on the charge-conjugate averaged partial branching ratios $= (Δ{\cal B}(B \to X_q \ell^+ \ell^-) + Δ{\cal B}(\bar{B} \to \bar{X}_q \ell^+ \ell^-))/2$, CP asymmetries in partial decay rates $(a_{CP})_q=(Δ{\cal B}(B \to X_q \ell^+ \ell^-) - Δ{\cal B}(\bar{B} \to \bar{X}_q \ell^+ \ell^-))/(2 < Δ{\cal B}_q >)$, and the ratio of the branching ratios $Δ{\cal R} = < Δ{\cal B}_d >/< Δ{\cal B}_s>$. For the central values of the CKM parameters, we find $ =(2.22^{+0.29}_{-0.30}) \times 10^{-6}$, $ =(9.61^{+1.32}_{-1.47}) \times 10^{-8}$, $(a_{CP})_s =-(0.19^{+0.17}_{-0.19})%$, $(a_{CP})_d =(4.40^{+3.87}_{-4.46})%$, and $Δ{\cal R} =(4.32 \pm 0.03)%$. The dependence of $$ and $Δ{\cal R}$ on the CKM parameters is worked out and the resulting constraints on the unitarity triangle from an eventual measurement of $Δ{\cal R}$ are illustrated.

Worker: Length 3.8-4.9 mm. - Head, excluding mandibles, 0.8 as long as wide, broadly impressed on posterior margin, sides nearly straight, gently converging to the eyes. Eyes feebly convex, posterior margin and posterior angle of clypeus on same level. Anterior lobe of clypeus with nearly straight margin. Antennal scrobes extending to occipital corners but feeble. Antennal scapes failing to reach occipital corners by a distance equal to nearly twice the distal diameter of the scapes. Terminal joint of funiculus equal in length to joints 2-5 taken together or slightly less than joints 7-9 taken together. - Thorax in profile as illustrated (Fig. 10). Viewed from above the epinotal ridges, which are very low, are strongly diverging posteriorly and terminate in slightly raised angles. - Petiole and gaster with distinct dorsal median impressions, laterally marginate.
Opaque; surface obscured by pilosity. Pilosity of numerous reclinate coarse hairs, appearing gray distally, black basally, and abundant fine subappressed and pale yellowish hairs. - Ferruginous.
Described from a colony taken by myself July 27, 1936, on the Oronoque River, tributary of the New River, main upper arm of the Courantyne River, British Guiana, in about 2°42' N. Lat. The nest of the ants was in the form of a crater leading by a narrow tunnel downward at a slight angle 8 cm. to a chamber, elliptical in form and 8 cm. high X 15 cm. wide. 5 cm. beneath this chamber was a second elliptical chamber 6 X 10 cm. In both were pendant fungus gardens with well-developed bromatia.
This species seemed fairly common in this region and the workers were never observed to form turret openings to their nests.
The species is named from the Arawak Indian name for Sericomyrmex.
From two cotypes of S. lutzi Wheeler this species differs in larger size, much shallower impression on posterior margin of head, higher posterior mesonotal tubercles, more angular epinotum, and in more abundant pubescence.

description: La migration est un sujet omniprésent dans l’actualité et qui engendre des modifications de l’identité occupationnelle des immigrés. C’est pourquoi les ergothérapeutes ont un rôle à jouer auprès de cette population. Objectif : Décrire et comprendre de manière précise les rôles et compétences mises en place par les ergothérapeutes pour répondre, à leur échelle, aux besoins occupationnels de requérants et de déboutés de l’asile dans le cadre de projets communautaires. Méthode : En raison d’un manque de littérature consacrée à la prise en charge de la population des requérants et déboutés de l’asile en ergothérapie d’une part, et de l’aspect novateur que propose l’association étudiée d’autre part, le choix s’est porté sur la réalisation d’une étude de type qualitative, descriptive et exploratoire. La récolte de données a été effectuée au travers d’une recherche documentaire sur l’association étudiée, d’entretiens semi-directifs auprès d’ergothérapeutes et d’observations participantes. Résultats : L’étude met en évidence l’importance de la création de ce dispositif afin d’offrir une prise en charge plus adaptée aux besoins spécifiques de cette population. Il en ressort également que les ergothérapeutes de l’association remplissent leur rôle d’expert en habilitation et s’engagent fortement dans le rôle d’agent de changement. Concernant les bénéfices potentiellement retirés par les participants, les résultats de l’étude montrent que ceux-ci correspondent aux besoins identifiés dans d’autres études, principalement des besoins occupationnels et identitaires. Conclusion : Les ergothérapeutes ont les compétences et les capacités de permettre aux populations issues de la migration de se développer, de trouver une place au sein de la communauté et de favoriser leur intégration dans leur pays d’accueil en facilitant leur engagement dans des occupations significatives.

description: Context. Solar dynamo models of Babcock-Leighton type typically assume the rise of magnetic flux tubes to be instantaneous. Solutions with high-magnetic-diffusivity have too short periods and a wrong migration of their active belts. Only the low-diffusivity regime with advective meridional flows is usually considered. Aims. In the present paper we discuss these assumptions and applied a time delay in the source term of the azimuthally averaged induction equation. This delay is set to be the rise time of magnetic flux tubes which supposedly form at the tachocline. We study the effect of the delay, which adds to the spacial non-locality a non-linear temporal one, in the advective but particularly in the diffusive regime. Methods. Fournier et al. (2017) obtained the rise time according to stellar parameters such as rotation, and the magnetic field strength at the bottom of the convection zone. These results allowed us to constrain the delay in the mean-field model used in a parameter study. Results. We identify an unknown family of solutions. These solutions self-quench, and exhibit longer periods than their non-delayed counterparts. Additionally, we demonstrate that the non-linear delay is responsible for the recover of the equatorward migration of the active belts at high turbulent diffusivities. Conclusions. By introducing a non-linear temporal non-locality (the delay) in a Babcock-Leighton dynamo model, we could obtain solutions quantitatively comparable to the solar butterfly diagram in the diffusion-dominated regime.

description: The effects of the presence of $Δ$-isobars in nuclear matter are studied in the framework of relativistic mean-field theory. The existence of stable nuclei at saturation density imposes constraints on the $Δ$-isobar self-energy and thereby on the mean-field coupling constants of the scalar and vector mesons with $Δ$-isobars. The range of possible values for the scalar and vector coupling constants of $Δ$-isobars with respect to the nucleon coupling is investigated and compared to recent predictions of QCD sum-rule calculations.

description: We report measurements of the far infrared transmission of superconducting YBa$_2$Cu$_3$O$_{7-δ}$ thin films from 5 cm$^{-1}$ to 200 cm$^{-1}$ in fields up to 14$T$. A Kramers-Kronig analysis of the magneto-transmission spectrum yields the magneto-conductivity tensor. The result shows that the magneto-conductivity of YBa$_2$Cu$_3$O$_{7-δ}$ is dominated by three terms: a London term, a low frequency Lorentzian ($ω_1\approx $ 3 cm$% ^{-1}$) of width $Γ_1=$ 10 cm$^{-1}$ and a finite frequency Lorentzian of width $Γ_2=$ 17 cm$^{-1}$ at $ω_2=$ 24 cm$^{-1}$ in the hole cyclotron resonance active mode of circular polarization.\\

description: This paper builds on the work of Acemoglu et al. (2012) and considers a production network with unobserved common technological factor and establishes general conditions under which the network structure contributes to aggregate fluctuations. It introduces the notions of strongly and weakly dominant units, and shows that at most a finite number of units in the network can be strongly dominant, while the number of weakly dominant units can rise with N (the cross section dimension). This paper further establishes the equivalence between the highest degree of dominance in a network and the inverse of the shape parameter of the power law. A new extremum estimator for the degree of pervasiveness of individual units in the network is proposed, and is shown to be robust to the choice of the underlying distribution. Using Monte Carlo techniques, the proposed estimator is shown to have satisfactory small sample properties. Empirical applications to US input-output tables suggest the presence of production sectors with a high degree of pervasiveness, but their effects are not sufficiently pervasive to be considered as strongly dominant.

description: This paper contrasts a decision maker's payoff under public and private information acquisition by a biased advisor. Both players agree on the optimal choice under certainty, but differ in how they trade off the loss from errors. The advisor can sequentially acquire informative test outcomes. If acquisition is private he decides in the final period which realizations to verifiably disclose. If players' preferences are sufficiently misaligned, the decision maker is weakly better off under private rather than public information acquisition. The effect on the advisor's payoff depends on the direction of his bias.

Employing a recent analysis of low energy (T_π< 100 MeV) πN data our sum rule implies σ(2μ^2) = 71\pm 9 MeV.

description: Characterising the long-term evolution of magnetic activity on Sun-like stars is important not only for stellar physics but also for understanding the environment in which planets evolve. In the past decades, many photometric surveys of open clusters have produced extensive rotation period measurements on Sun-like stars of different ages. I use these data to infer the long-term evolution of Ca II chromospheric and X-ray coronal emission on solar mass stars combining a best fit parametric model of their rotation evolution with empirical rotation-activity relationships.

description: We discuss the variational principle within Quantum Mechanics in terms of the noncommutative even Space Time sub-Algebra, the Clifford $\Ra$-algebra $Cl_{1,3}^+$. A fundamental ingredient, in our multivectorial algebraic formulation, is the adoption of a $\D $-complex geometry, $\D \equiv span_{\RR} \{1,γ_{21} \}$, $γ_{21} \in Cl_{1,3}^+$. We derive the Lagrangian for the Dirac-Hestenes equation and show that such Lagrangian must be mapped on $\D \otimes {\cal F}$, where $\cal F$ denotes an $\Ra$-algebra of functions.

An Effective Equation of State for Dense Matter with Strangeness

description: An effective equation of state (EoS) which generalizes the Lattimer-Swesty equation for nuclear matter is presented for matter at supernuclear densities including strange baryons. It contains an adjustable baryon potential energy density, based on models of local potentials for the baryon-baryon interactions. The features of the equation rely on the properties of nuclei for the nucleon-nucleon interactions, and mainly on experimental data from hypernuclei for the hyperon-nucleon and hyperon-hyperon interactions. The EoS is used to calculate equilibrium compositions and thermodynamic properties of high density matter with strangeness in two astrophysical contexts: neutron star matter (transparent to neutrinos) and proto-neutron star matter (opaque to neutrinos). The effective EoS reproduces typical properties of high density matter found in theoretical microscopic models. Of these, the main result is that hyperons appear in both types of matter at about twice the nuclear saturation density, and that their appearance significantly softens the EoS. The range of maximal masses of neutron stars found in a comprehensive parameter survey is 1.4-1.7 $M_\odot$. Another typical result is that the maximal mass of a proto-neutron star with strange baryons is higher than that of an evolved neutron star (opposite to the case of nuclear matter), setting the stage for a "delayed collapse" scenario.

How to judge whether supporting solar PV is justified

description: Renewable electricity, particularly solar PV, creates external benefits of learning-by-doing that drives down costs. If eventually economic, these technologies will thereafter create social value by reducing carbon emissions with value greater than the cost of abatement. This paper sets out a method for assessing whether a trajectory of investment that involves initial subsidies is justified by the subsequent learning-by-doing spillovers and whether it is worth accelerating current investment rates. Given current costs and learning rates, accelerating the current rate of investment appears globally socially beneficial, particularly if that investment is deployed in high insolation locations.

Worker: Length 2.6 mm. - Head, excluding mandibles, 0.9 as long as broad, broadly impressed at posterior margin. Antennal scrobes feeble, not reaching occipital corners. Antennal scapes not quite extending to occipital corners. Terminal joint of funiculus about as long as joints 6-9 taken together or joints 2-6 taken together. Joints 2-9 of funiculus broader than long.
Thorax, in profile, with pronotum evenly convex, rising steeply to the acutely pointed anterior mesonotal tubercles. Posterior mesonotal tubercles slightly lower than anterior because of truncate apex. Mesoepinotal depression moderately deep and rounded, rising to the angular anterior margin of basal surface of epinotum. Basal surface of epinotum bordered by distinct, though irregular, diverging lateral ridges which terminate in stout epinotal tubercles. These are as massive at the base as the mesonotal tubercles and obliquely truncate at apex. Declivous surface of epinotum irregularly concave.
Sloping anterior surface of petiole very slightly convex. Dorsal surface in profile slightly concave, angle between the two surfaces irregularly rounded. Dorsal surface of postpetiole in profile plane, rising anteriorly.
Gaster and pedicel from above with longitudinal median impression, gaster feebly marginate on sides. Legs of moderate length and stoutness.
Opaque, surface obscured by pilosity. - Abundant fine, whitish pubescence, with sparser and coarser reclinate, dark hairs. - Dull ferruginous, appendanges paler distally.
Holotype: One worker taken at King Frederick William, the Fourth Falls on the Upper Courantyne River, Surinam, December 29, 1935, by Dr. J. G. Myers (No. 5931).
This species, dedicated to my friend Dr. Myers, who discovered it, differs from two cotypes of S. lutzi Wheeler in distinctly smaller size, more shallowly impressed posterior margin of head, feebler antennal scrobes, in much lower anterior mesonotal tubercles, higher epinotal tubercles and in other ways. From S. urichi Forel and S. harekulli sp. nov. it differs chiefly in lower anterior mesonotal tubercles, in higher epinotal tubercles, and in smaller size.

Flavor Changing Effects in Theories with a Heavy Z' Boson with Family Non-Universal Couplings

description: There are theoretical and phenomenological motivations that there may exist additional heavy Z' bosons with family non-universal couplings. Flavor mixing in the quark and lepton sectors will then lead to flavor changing couplings of the heavy Z', and also of the ordinary Z when Z-Z' mixing is included. The general formalism of such effects is described, and applications are made to a variety of flavor changing and CP-violating tree and loop processes. Results are described for three specific cases motivated by a specific heterotic string model and by phenomenological considerations, including cases in which all three families have different couplings, and those in which the first two families, but not the third, have the same couplings. Even within a specific theory the results are model dependent because of unknown quark and lepton mixing matrices. However, assuming that typical mixings are comparable to the CKM matrix, processes such as coherent mu-e conversion in a muonic atom, K^0-\Bar{K}^0 and B-\Bar{B} mixing, epsilon, and epsilon'/epsilon lead to significant constraints on Z' bosons in the theoretically and phenomenologically motivated range M_{Z'} \sim 1 TeV.

description: We consider cosmological implications of the formation of first stellar size black holes (BHs) in the universe. Such BHs form and grow by accretion in minihaloes of masses $\simeq 10^5-10^7~M_\odot$, and emit non-thermal radiation which impact the ionization and thermal state of the IGM. We compute the implications of this process. We show that the influence regions for hydrogen increase to 10kpc (physical length) for non-growing BHs to more than 0.3--1Mpc for accreting BHs, the influence regions are ten times smaller for singly ionized helium. We consider three possible observables from the influence zones around accreting BHs during $8.5

description: Energy considerations are core to mission delivery of armed forces worldwide. The interaction between military energy issues and non-military energy issues is not often explicitly treated in the literature or media, although in the last decade there has been some increase driven especially by the issues of clean energy. It is recognized that the military has for more than a hundred years taken a leadership role in terms on research and development (R&D) of specific energy technologies - most commonly where they are applicable in theater. More recently that R&D leadership has moved to the energy efficiency of home-country bases, and the development of renewable energy projects for areas as diverse as mini-grids for in-country installations, to alternative fuels for submarines and jets. Nevertheless, the military in most major countries tends to see energy issues as a matter of mission delivery or conversely the denial of enemy energy supply chains as a source of advantage. In this paper we explore the evolving relationship between energy issues and defense planning, and show how these developments have implications for military tactics and strategy and for civil energy policy.

description: We review results obtained using Shell Model Monte Carlo (SMMC) techniques. These methods reduce the imaginary-time many-body evolution operator to a coherent superposition of one-body evolutions in fluctuating one-body fields; the resultant path integral is evaluated stochastically. After a brief review of the methods, we discuss a variety of nuclear physics applications. These include studies of the ground-state properties of pf-shell nuclei, Gamow-Teller strength distributions, thermal and rotational pairing properties of nuclei near N=Z, $γ$-soft nuclei, and $ββ$-decay in ^{76}Ge. Several other illustrative calculations are also reviewed. Finally, we discuss prospects for further progress in SMMC and related calculations.

description: Mycetophylax brittoni Wheeler littoralis, var. nov.
Fifteen worker cotypes. of brittoni were compared with workers taken by myself along the east of Trinidad jupon many occasions. These specimens differ from the typical form in the following: Thorax in profile evenly convex instead of flattened; basal surface of epinotum separated from declivous surface by a pair of small but distinct tubercles, postpetiole from above distinctly longer than broad, sides and anterior margin forming an even convexity. Hairs of head somewhat shorter, finer, and more numerous. Color black with appendages dark brown. The brittoni cotypes were distinctly paler in color though this may be caused by fading.
The males, 2.3-2.5 mm. in length, have the head, excluding mandibles, a trifle longer than wide back of eyes and the occipital margin straight with angulate corners. The epinotum is without tubercles but with a faint indication of angularity at the point where they would be situated. The color is black with dark brown appendages and pale brown mandibles. Wings hyaline, veins yellowish brown.

description: In this paper, learning of tree-structured Gaussian graphical models from distributed data is addressed. In our model, samples are stored in a set of distributed machines where each machine has access to only a subset of features. A central machine is then responsible for learning the structure based on received messages from the other nodes. We present a set of communication efficient strategies, which are theoretically proved to convey sufficient information for reliable learning of the structure. In particular, our analyses show that even if each machine sends only the signs of its local data samples to the central node, the tree structure can still be recovered with high accuracy. Our simulation results on both synthetic and real-world datasets show that our strategies achieve a desired accuracy in inferring the underlying structure, while spending a small budget on communication.
