Scoliosoma

description: Scoliosoma gen. nov.
Diagnosis. Female body strongly curved ventrally. Prosome divided only by constrictions. Brood pouch formed by fused swollen third and fourth pedigerous somites. Urosome rather long, apparently 6-segmented although first urosomite (fifth pedigerous somite) almost completely fused to prosome. Genital somite free. Caudal ramus small, armedwith 3 small setae. Rostrum short. Antennule broad, leaf-like, unsegmented or obscurely segmented, armed with few small setae. Antenna 4- segmented with small terminal claw. Labrum short and broad. Mandible consistingof coxa and palp; coxal gnathobase broad, bearing large, spiniform mediodistal tooth and serrate medial margin; palp consisting of basis, exopod and endopod, but rami may be fused with basis; basiswith 1 seta mediodistally; exopodwith 4 setae; endopod unsegmented with 5 setae, or 2-segmented with 1 and 4 setae on first and second segments, respectively. Maxillule comprising precoxal arthrite armed with 5 setae and lobate palp bearing 5 setae. Maxilla consisting of syncoxa, basis, and 1- or 2-segmented endopod; basis with robust claw only. Maxilliped represented by small lobe bearing 2 setae distally. Legs 1–4 rudimentary. Legs 1–3 bilobed; lobes not articulated at base and armed with minute setae. Leg 4 as small lobe. Leg 5 absent.
Type species. Scoliosoma haplomerosum gen. et sp. nov. by original designation.
Other included species. Scoliosoma dimerosum gen. etsp. nov.
Etymology. The generic name is from the Greek scoli (=curved, crooked) and soma (=body), referring the curved body of the adult female in species of the new genus. Gender neuter.
Remarks. Scoliosoma gen.nov. resembles Gallincola gen. nov.: they have a similar body form and both have a strong distal tooth on the mandibular gnathobase. Interestingly, both live in galls in solitary ascidians. However, the cephalic appendages of Scoliosoma gen. nov. are much more simplified than in Gallincola gen. nov. The mandibular exopod is armed with 5 setae in Gallincola gen. nov. but with 4 setae in Scoliosoma gen. nov. The maxillule of Gallincola gen. nov. bears as many as 9 setae on the arthrite and has a biramous palp but this appendage in Scoliosoma gen. nov. bears a total of only 5 setae on the arthrite and has a rudimentary, lobate palp. Othernotable differences include: in Scoliosoma gen. nov. the urosome is 5-segmented compared to 4-segmented in Gallincola gen. nov., the antennule is broad, leaf-like compared to elongate in Gallincola gen. nov., and the maxillary syncoxa has only 2 endites compared with 3 endites in Gallincola gen. nov.

description: (Abridged) The violent hierarchical nature of the LCDM cosmology poses serious difficulties for the formation of disk galaxies. To help resolve these issues, we describe a new, merger-driven scenario for the cosmological formation of disk galaxies at high redshifts that supplements the standard model based on dissipational collapse.In this picture, large gaseous disks may be produced from high-angular momentum mergers of systems that are gas-dominated, i.e. M_gas/(M_gas +M_star > 0.5 at the height of the merger. Pressurization from the multiphase structure of the interstellar medium prevents the complete conversion of gas into stars during the merger, and if enough gas remains to form a disk, the remnant eventually resembles a disk galaxy. We perform numerical simulations of galaxy mergers to study how supernovae feedback strength, supermassive black hole growth and feedback, progenitor gas fraction, merger mass-ratio, and orbital geometry impact the formation of remnant disks. We find that disks can build angular momentum through mergers and the degree of rotational support of the baryons in the merger remnant is primarily related to feedback processes associated with star formation. Disk-dominated remnants are restricted to form in mergers that are gas-dominated at the time of final coalescence and gas-dominated mergers typically require extreme progenitor gas fractions (>80%). We also show that the formation of rotationally-supported stellar systems in mergers is not restricted to idealized orbits, or major or minor mergers. We suggest that the hierarchical nature of the LCDM cosmology and the physics of the interstellar gas may act together to form spiral galaxies by building the angular momentum of disks through early, gas-dominated mergers.

description: This paper has examined the Samuelson’s hypothesis which states that the price volatility increases as the contract nears its maturity. It has also examined the BCSS hypothesis which provides that negative covariance between the spot price and net cost of carry explains the maturity effect. The study has examined these hypotheses on the data for wheat and pepper futures contract traded at NCDEX from the date of listing of the contract to 31st March 2007 and the maturity effect has been examined for each contract individually. The study has indicated that maturity effect is present in around 45 per cent of the wheat and pepper contracts. Evidence supporting the BCSS hypothesis is present more strongly in the case of wheat as compared to pepper and 79 per cent of the contracts having maturity effect have depicted negative covariance in the case of wheat. Thus, it can be concluded that maturity effect is present and it is explained to a large extent by the negative co-variance between spot price and net carry cost. The study has observed that there is further scope for research in this area in relation to other agricultural commodities and also metals. Further studies can also be undertaken to find the informational efficiency and the reaction of informational flow to identify the reasons for the presence or absence of maturity effect.

description: A direct generalization of the transverse momentum integrated(TMI) light-cone wave function to define a transverse momentum dependent(TMD) light-cone wave function will cause light-cone singularities and they spoil TMD factorization. We motivate a definition in which the light-cone singularities are regularized with non-light like Wilson lines. The defined TMD light-cone wave function has some interesting relations to the corresponding TMI one. When the transverse momentum is very large, the TMD light-cone wave function is determined perturbatively in term of the TMI one. In the impact $b$-space with a small $b$, the TMD light-cone wave function can be factorized in terms of the TMI one. In this letter we study these relations. By-products of our study are the renormalization evolution of the TMI light-cone wave function and the Collins-Soper equation of the TMD light-cone wave function, the later will be useful for resumming Sudakov logarithms.

description: Monoclinic bismuth vanadate (BiVO$_4$) is a promising $n$-type semiconductor for applications in sunlight-driven water splitting. Several studies have shown that its photocatalytic activity is greatly enhanced by high concentrations of Mo and W dopants. In the present work, we performed \textit{ab initio} calculations to assess the most favorable relative position between Mo-related pairs in BiVO$_4$. Surprisingly, we verify that the lowest energy configuration for Mo$_{\text{V}}$ pairwise defects in BiVO$_4$ occurs on nearest-neighbor sites, despite the higher electrostatic repulsion and larger strain on the crystal lattice. Similar results were observed for W$_{\text{V}}$ defect pairs in W-doped BiVO$_4$. We show that the origin of this effect lies in a favorable hybridization between the atomic orbitals of the impurities that is only verified when they are closest to each other, resulting in an enthalpy gain that overcomes the repulsive components of the pair formation energy. As a consequence, Mo and/or W doped BiVO$_4$ are likely to present donor-donor defect complexes, which is an outcome that can be applied in experimental approaches for improving the photocatalytic activity of these metal oxides.

description: We study the properties of galaxies at z=2 in a Lambda cold dark matter universe, using two different types of hydrodynamic simulation methods -- Eulerian TVD and smoothed particle hydrodynamics (SPH) -- and a spectrophotometric analysis in the U_n, G, R filter set. The simulated galaxies at z=2 satisfy the color-selection criteria proposed by Adelberger et al. (2004) and Steidel et al. (2004) when we assume Calzetti extinction with E(B-V)=0.15. We find that the number density of simulated galaxies brighter than R<25.5 at z=2 is about 1e-2 h^3 Mpc^-3 for E(B-V)=0.15, which is roughly twice that of the number density found by Erb et al. (2004) for the UV bright sample. This suggests that roughly half of the massive galaxies with M*>10^{10} Msun/h at z=2 are UV bright population, and the other half is bright in the infra-red wavelengths. The most massive galaxies at z=2 have stellar masses >= 10^{11-12} Msun. They typically have been continuously forming stars with a rate exceeding 30 Msun/yr over a few Gyrs from z=10 to z=2, together with significant contribution by starbursts reaching up to 1000 Msun/yr which lie on top of the continuous component. TVD simulations indicate a more sporadic star formation history than the SPH simulations. Our results do not imply that hierarchical galaxy formation fails to account for the observed massive galaxies at z>=1. The global star formation rate density in our simulations peaks at z>=5, a much higher redshift than predicted by the semianalytic models. This star formation history suggests early build-up of the stellar mass density, and predicts that 70 (50, 30)% of the total stellar mass at z=0 had already been formed by z=1 (2, 3). Upcoming observations by Spitzer and Swift might help to better constrain the star formation history at high redshift.

Toward a Theory of Chaos
Creators: name: Sengupta, A.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: This paper formulates a new approach to the study of chaos in discrete dynamical systems based on the notions of inverse ill-posed problems, set-valued mappings, generalized and multivalued inverses, graphical convergence of a net of functions in an extended multifunction space, and the topological theory of convergence. Order, chaos, and complexity are described as distinct components of this unified mathematical structure that can be viewed as an application of the theory of convergence in topological spaces to increasingly nonlinear mappings, with the boundary between order and complexity in the topology of graphical convergence being the region in Multi(X) that is susceptible to chaos. The paper uses results from the discretized spectral approximation in neutron transport theory and concludes that the numerically exact results obtained by this approximation of the Case singular eigenfunction solution is due to the graphical convergence of the Poisson and conjugate Poisson kernels to the Dirac delta and the principal value multifunctions respectively. In Multi(X), the continuous spectrum is shown to reduce to a point spectrum, and we introduce a notion of latent chaotic states to interpret superposition over generalized eigenfunctions. Along with these latent states, spectral theory of nonlinear operators is used to conclude that nature supports complexity to attain efficiently a multiplicity of states that otherwise would remain unavailable to it.

description: Contoura gen. nov.
Diagnosis. Body inflated. Urosome greatly reduced, indistinctly 1- or 2-segmented. Caudal rami rudimentary, not articulated from abdomen, lacking setae. Rostrum welldeveloped. Antennule short and broad, unsegmented or partially segmented; setae vestigial. Antenna 3-segmented, consisting of coxa, basis, and unsegmented endopod with small terminal claw. Labrum broad. Mandible consisting of coxa and palp; coxa with broad gnathobase with uneven, serrate medial margin; palp unsegmented, unilobate with vestigial exopod or lacking trace of exopod, armed with few rudimentary setae. Maxillule consisting of precoxa and palp; precoxa bearing 3 large, spiniform processes on arthrite; palp distally bilobed with large subdistal seta on medial margin and vestigial or transformed setae on distal lobes. Maxilla 4-segmented, comprising syncoxa, basis, and 2-segmented endopod; syncoxawith 1 or 2 smallsetae; basis with large, robust claw plus 1 seta; endopod with 3 or 4 small setae. Maxilliped as small lobe tipped with 1 or 2 setae. Leg 1 as unsegmented and unarmed plate, obscurely bilobed distally, or bearing lobe distally. Leg 2 absent or represented by small lobe. Legs 3 and 4 absent. Leg 5 represented by pair of conical, sclerotized processes.
Type species. Contoura globosa gen. et sp. nov. by original designation.
Other included species. Contoura elliptica gen. et sp. nov.
Etymology. The generic name is a combination of Greek cont (=short) and ur (=tail) and alludes to the short urosome of the new genus. Gender feminine.
Remarks. Two species are included in the new genus Contoura. Although they have remarkably different body form in the adult female, their cephalic appendages are highly derived and astonishingly similar. The most outstanding feature of the new genus is the presence of 3 large, spiniform teeth on the precoxal arthrite of the maxillule. The rudimentary urosome, the leaf-like antennule, the enlarged claw on the basis of the maxilla, the rudimentary leg 1, and the transformed leg 5 consisting of paired conical processes are all additional derived features of the new genus. Both speciesof Contoura gen. nov. are distributed in the western Atlantic.

description: This paper deals with the ex-ante analysis of the effects of farm subsidies on farm behaviour. Beside that the risk factor is implemented in the farm model to reflect and quantify potential (negative) impact on farm results. A farm-level optimization model is used to assess the effects of different kind of policies and risk on production structure, income indicators and land use management. It appeared that a reasonable level of risk (via income variation) have impact, but not significant. If liberalisation would have happened (zero direct and disadvantageous payments) production would homogenised, 30% of land would remained abandoned, production and income would clearly decline. Other scenario points out that environmental objectives (here through more extensively managed land) could not be necessarily more costly, but in such a case without accompanying livestock. To increase profitable livestock production requires to provide grassland and animal payments above the current level (obviously in addition to stimulating production economizing) whereas both payments should be conditional to each other.
The staging of APEC
Creators: name: Chartrand, Lise L.
Publisher: name: University of British Columbia
Year: 2009

description: In 1993, the Asia-Pacific Economic Cooperation forum (APEC) held the first APEC Economic Leaders Meeting (AELM). Raising APEC interaction to the top track, the level of leaders, proved to be an effective and powerful dynamic; the AELM continues to meet annually and to shape APEC policy. The focus on the AELM as the source of vision and direction reinforces the pivotal importance of this political assemblage, reassures the populace that leaders do prevail and all is well: essential ingredients, according to Clifford Geertz, of political theater. The role of journalists, the contemporary scribes or critics, is to inform the audience of this political drama. The objective of this research is to demonstrate that real political value exists in the 'Staging of APEC' in terms of effective economic and political integration of benefit to broad regional interests. The findings draw on the results of a content analysis of news reports covering the first six years of the AELM (1993-1998). Formally, the AELM is an opportunity for regional political leaders to engage in regional policy formation outlined by the pillars of APEC (trade liberalization, facilitation and cooperation) guided by the principals of open regionalism and concerted unilateralism. Activity on the formal, or main stage, also flows to the small stage where leaders merge in a neutral venue. On this stage, leaders are free to examine distinctly non-economic, yet intersecting interests including domestic agendas, human rights and pluri-lateral security concerns. Together, these dual stages, neither one complete without the other, form the political theatre of APEC and provide the value added for the leaders and ultimately for the Asia – Pacific region.

description: We introduce the spin and momentum dependent {\em force operator} which is defined by the Hamiltonian of a {\em clean} semiconductor quantum wire with homogeneous Rashba spin-orbit (SO) coupling attached to two ideal (i.e., free of spin and charge interactions) leads. Its expectation value in the spin-polarized electronic wave packet injected through the leads explains why the center of the packet gets deflected in the transverse direction. Moreover, the corresponding {\em spin density} will be dragged along the transverse direction to generate an out-of-plane spin accumulation of opposite signs on the lateral edges of the wire, as expected in the phenomenology of the spin Hall effect, when spin-$\uparrow$ and spin-$\downarrow$ polarized packets (mimicking the injection of conventional unpolarized charge current) propagate simultaneously through the wire. We also demonstrate that spin coherence of the injected spin-polarized wave packet will gradually diminish (thereby diminishing the ``force'') along the SO coupled wire due to the entanglement of spin and orbital degrees of freedom of a single electron, even in the absence of any impurity scattering.

description: In the context of improvement of economic life, normative economics has to cope, if it is not only a theoretical construct, with various facts which are brought by the economic reality. Becoming aware of the mutual causality of economic phenomena and processes, the consideration of these facts should first define factually a particular area of interest and then identify formally a direction of its improvement. To reduce regional disparities, the key points are both the selection of disparities identification criterions and the specification of values of these criterions. The paper deals with the area which is nowadays relatively common – regional disparities. The improvement in this sense focuses on the decreasing of differences between particular regions regarding the defined values, respectively levels of partial criterions which serve as a base for identification of regional differences. Data envelopment analysis (DEA) and cluster analysis are used to evaluation of the regions.

Type and only species. Unimeria longipedata gen. et sp. nov. by original designation.
Etymology. The generic name is derived from the Greek uni (=one) and mer (=a part) and refers to the unsegmented body of the type species. Gender feminine.
Remarks. The type species could not be assigned to any known notodelphyid genera because it exhibits a unique combination of highly derived and plesiomorphic character states. The derived states include: the urosome is small and unsegmented, the medial margin of mandibularcoxais pectinate, themaxillule isvery reduced (represented by a lobe bearing setae), the maxilliped is absent, the swimming legs are unsegmented but retain elongate rami, and leg 5 is absent. However, the presence of 6 caudal setae and the setation of the mandibular palp are both relatively plesiomorphic features. Unimeria gen. nov. is established to accommodate U. longipedata gen. etsp. nov.

description: Classical simulation of quantum computation is vital for verifying quantum devices and assessing quantum algorithms. We present a new quantum circuit simulator developed on the Sunway TaihuLight supercomputer. Compared with other simulators, the present one is distinguished in two aspects. First, our simulator is more versatile. The simulator consists of three mutually independent parts to compute the full, partial and single amplitudes of a quantum state with different methods. It has the function of emulating the effect of noise and support more kinds of quantum operations. Second, our simulator is of high efficiency. The simulator is designed in a two-level parallel structure to be implemented efficiently on the distributed many-core Sunway TaihuLight supercomputer. Random quantum circuits can be simulated with 40, 75 and 200 qubits on the full, partial and single amplitude, respectively. As illustrative applications of the simulator, we present a quantum fast Poisson solver and an algorithm for quantum arithmetic of evaluating transcendental functions. Our simulator is expected to have broader applications in developing quantum algorithms in various fields.

description: In spite of their importance for understanding phonon transport phenomena in thin films and polycrystalline solids, the effects of boundary roughness scattering on phonon specularity and coherence are poorly understood because there is no general method for predicting their dependence on phonon momentum, frequency, branch and boundary morphology. Using the recently formulated atomistic S-matrix method, we develop a theory of boundary roughness scattering to determine the mode-resolved phonon coherence and specularity parameters from the scattering amplitudes. To illustrate the theory, we apply it to phonon scattering in realistic nonsymmetric graphene grain boundary (GB) models derived from atomic structure predictions. The method is validated by comparing its predictions with frequency-resolved results from lattice dynamics-based calculations. We prove that incoherent scattering is almost perfectly diffusive. We show that phonon scattering at the graphene GB is not diffuse although coherence and specularity are significantly reduced for long-wavelength flexural acoustic phonons. Our approach can be generalized to other atomistic boundary models.

description: The possibility of ferromagnetic and antiferromagnetic phase transitions in symmetric nuclear matter is analyzed within the framework of a Fermi liquid theory with the effective Gogny interaction. It is shown that at some critical density nuclear matter with D1S effective force undergoes a phase transition to the antiferromagnetic spin state (the opposite direction of neutron and proton spins). The self--consistent equations of spin polarized nuclear matter with D1S force have no solutions, corresponding to the ferromagnetic spin ordering (the same direction of neutron and proton spins) and, hence, the ferromagnetic transition does not appear. The dependence of antiferromagnetic spin polarization parameter as a function of density is found at zero temperature.

description: We have found a way to analyze Edwards' density of states for static granular packings in the special case of round, rigid, frictionless grains assuming constant coordination number. It obtains the most entropic density of single grain states, which predicts several observables including the distribution of contact forces. We compare these results against empirical data obtained in dynamic simulations of granular packings. The agreement is quite good, helping validate the use of statistical mechanics methods in granular physics. The differences between theory and empirics are mainly related to the coordination number, and when the empirical data are sorted by that number we obtain several insights that suggest an underlying elegance in the density of states.

description: It is possible to consider the production chain as a highly complicated system, within the framework of which different links and mutual relations function. Therefore it is necessary to analyze the complexity of the production chain functioning for the purpose of enhanced knowledge on the existence and the regularities functioning among different production elements. The contribution deals with an analysis of the price transmission in the production chain of cereals, within which only certain partial parts have been earmarked. Cointegration analysis, VECM and impulse-response analysis have been used for the price transmission analysis. Information mentioned in the paper resulted from the solution of a research intention VZ MSM 6046070906 „The Economics of resources of Czech agriculture and their efficient use in framework of multifunctional agrifood systems“.

description: We report the grand-canonical solution of a ternary mixture of discrete hard spheres defined on a Husimi lattice built with cubes, which provides a mean-field approximation for this system on the cubic lattice. The mixture is composed by point-like particles (0NN) and particles which exclude up to their first (1NN) and second neighbors (2NN), with activities $z_0$, $z_1$ and $z_2$, respectively. Our solution reveals a very rich thermodynamic behavior, with two solid phases associated with the ordering of 1NN ($S1$) or 2NN particles ($S2$), and two fluid phases, being one regular ($RF$) and the other characterized by a dominance of 0NN particles ($F0$ phase). However, in most part of the phase diagram these fluid ($F$) phases are indistinguishable. Discontinuous transitions are observed between all the four phases, yielding several coexistence surfaces in the system, among which a fluid-fluid and a solid-solid demixing surface. The former one is limited by a line of critical points and a line of triple points (where the phases $RF$-$F0$-$S2$ coexist), both meeting at a special point, after which the fluid-fluid coexistence becomes metastable. Another line of triple points is found, connecting the $F$-$S1$, $F$-$S2$ and $S1$-$S2$ coexistence surfaces. A critical $F$-$S1$ surface is also observed meeting the $F$-$S1$ coexistence one at a line of tricritical points. Furthermore, a thermodynamic anomaly characterized by minima in isobaric curves of the total density of particles is found, yielding three surfaces of minimal density in the activity space, depending on which activity is kept fixed during its calculation.

description: Viruses cause illness both directly by attacking and destroying cells, and indirectly by prompting inflammation as the immune system battles the virus. The severity of such illness appears sometimes to be correlated with the age of the infected organism. We examine how variation of apoptosis behaviour with age might affect both the success of a body’s fight against a virus, and the extent of inflammation.
Existence of two-channel Kondo regime for tunneling impurities with resonant scattering

description: Dynamical tunneling systems have been proposed earlier to display a two-channel Kondo effect, the orbital index of the particle playing the role of a pseudospin in the equivalent Kondo problem, and the spin being a silent channel index. However, as shown recently by Aleiner et al. [Phys. Rev. Lett. 86, 2629 (2001)], the predicted two-channel Kondo behavior can never be observed in the weak coupling regime, where the tunneling induced splitting of the levels of the tunneling system always dominates the physics. Here we show that the above scenario changes completely if the conduction electrons are scattered by resonant scattering off the tunneling impurity; Then - as a non-perturbative analysis reveals - the two-channel Kondo regime can easily be reached.

description: The present paper describes the strategy of introducing future knowledge management system at farms. The FUTUREFARM and PREZEM projects strive to apply new knowledge management methods in arable farming where they guarantee an easy adaptation of the farming sector to the everchanging conditions in short, middle and long-term perspective. The knowledge management methods have to be put into practice on strategic, tactic and operational planning levels. Based on the project analysis and workshops with farmers, the paper brings an outline of the main goals and obstacles for new knowledge management methods adoption and furthermore defines the target groups and relevant methods of dealing with them.
Theory of the propagation of coupled waves in arbitrarily-inhomogeneous stratified media

description: We generalize the invariant imbedding theory of the wave propagation and derive new invariant imbedding equations for the propagation of arbitrary number of coupled waves of any kind in arbitrarily-inhomogeneous stratified media, where the wave equations are effectively one-dimensional. By doing this, we transform the original boundary value problem of coupled second-order differential equations to an initial value problem of coupled first-order differential equations, which makes the numerical solution of the coupled wave equations much easier. Using the invariant imbedding equations, we are able to calculate the matrix reflection and transmission coefficients and the wave amplitudes inside the inhomogeneous media exactly and efficiently. We establish the validity and the usefulness of our results by applying them to the propagation of circularly-polarized electromagnetic waves in one-dimensional photonic crystals made of isotropic chiral media. We find that there are three kinds of bandgaps in these structures and clarify the nature of these bandgaps by exact calculations.

Misconceptions of migration : contemporary Cambodian migration into Thailand
Creators: name: Bullock, Shannon Marie
Publisher: name: University of British Columbia
Year: 2009

description: With an estimated 88,000 Khmer migrants subject to situations of exploitation in Thailand's unskilled labour market, cross-border migration from Cambodia into Thailand is becoming an increasingly serious issue. Governments, 'nongovernmental organizations and international organizations are focusing their efforts on preventing cross-border migration into Thailand, but, despite their efforts, policies and programmes have failed to produce the desired ) result - a decline in illegal migration, trafficking, and smuggling between these two countries. I would argue that migration from Cambodia into Thailand is not preventable through policy and programmatic interventions. By using a tri-causal migration framework, based on push, pull, and network factors, to explain the causes of migration between these two countries, it becomes evident that pull factors play the greatest role in motivating Khmer migrants to search for employment in Thailand, but these factors are related to structural conditions reflective of the country's greater level of development - conditions that cannot be altered through intervention. Relevant actors--have primarily tried to prevent migration by addressing push and network factors, but this approach addresses global misconceptions of migration, trafficking and smuggling that are not reflective of current migration dynamics between Cambodia and Thailand. Misconceptions that poverty is the root cause of migration, trafficking is a separate issue from other forms of migration, and migration is preventable have detracted actors from addressing the more pertinent issue - the issue of migrant exploitation. Migrant exploitation stems from the complex political, economic and cultural factors that shape Thailand's current migration policies. While there is no simple solution for Thailand's migration management problems, greater efforts should be made to create legal migration channels that protect Khmer workers from labour exploitation, while providing Thai employers with more legitimate access to low-cost labour supplies in the region.

description: In this paper, we propose a unified theoretical and practical spherical approximation framework for functional inverse problems on the hypersphere. More specifically, we consider recovering spherical fields directly in the continuous domain using functional penalised basis pursuit problems with gTV regularisation terms. Our framework is compatible with various measurement types as well as non-differentiable convex cost functionals. Via a novel representer theorem, we characterise their solution sets in terms of spherical splines with sparse innovations. We use this result to derive an approximate canonical spline-based discretisation scheme, with vanishing approximation error. To solve the resulting finite-dimensional optimisation problem, we propose an efficient and provably convergent primal-dual splitting algorithm. We illustrate the versatility of our framework on real-life examples from the field of environmental sciences.

description: We compute the one loop, $O(þ)$ correction to the vertex in the noncommutative Chern-Simons theory with scalar fields in the fundamental representation. Emphasis is placed on the parity odd part of the vertex, since the same leads to the magnetic moment structure. We find that, apart from the commutative term, a $þ$-dependent magnetic moment type structure is induced. In addition to the usual commutative graph, cubic photon vertices also give a finite $þ$ dependent contribution. Furthermore, the two two-photon vertex diagrams, that give zero in the commutative case yield finite $þ$ dependent terms to the vertex function.

A representation of complex rational numbers in quantum mechanics
Creators: name: Benioff, Paul
Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A representation of complex rational numbers in quantum mechanics is described that is not based on logical or physical qubits. It stems from noting that the zeros in a product qubit state do not contribute to the number. They serve only as place holders. The representation is based on the distribution of four types of systems on an integer lattice. The four types, labelled as positive real, negative real, positive imaginary, and negative imaginary, are represented by creation and annihilation operators acting on the system vacuum state. Complex rational string number states correspond to strings of creation operators acting on the vacuum. Various operators, including those for the basic arithmetic operations, are described. The representation used here is based on occupation number states and is given for bosons and fermions.
