description: We present a manifestly $N=2$ supersymmetric formulation of $N=2$ super-$W_3^{(2)}$ algebra (its classical version) in terms of the spin 1 unconstrained supercurrent generating a $N=2$ superconformal subalgebra and the spins 1/2, 2 bosonic and spins 1/2, 2 fermionic constrained supercurrents. We consider a superfield reduction of $N=2$ super-$W_3^{(2)}$ to $N=2$ super-$W_3$ and construct a family of evolution equations for which $N=2$ super-$W_3^{(2)}$ provides the second hamiltonian structure.

description: On January 20 and 21, 1988, Daniel R. Bontrager of Archaeological Research Services, Inc. (ARS) performed a cultural resources survey of an approximately 130 acre parcel at the proposed location of the Interstate 10 - Outer Loop Freeway Interchange in west Phoenix, Maricopa County, Arizona. The survey was requested and authorized by the Arizona Department of Transportation (ADOT) for Project RAM-600-0-311 under Contract 86-39 with ARS for Statewide Archaeological Investigations (Project N-901-279) in order to determine if important cultural resources (which may include prehistoric or historic archaeological sites or objects, historically or architecturally significant structures or buildings) were present within the project area which could be adversely affected by the proposed undertaking. The project area consists of private land for which ADOT has obtained rights-of-entry for survey purposes. The parcel is defined by agricultural fields which are currently under cultivation.
On the chiral and deconfinement phase transitions in parity-conserving QED_3 at finite temperature

description: We present some results about the interplay between the chiral and deconfinement phase transitions in parity-conserving QED3 (with N flavours of massless 4 component fermions) at finite temperature. Following Grignani et al (Phys. Rev. D53, 7157 (1996), Nucl. Phys. B473, 143 (1996)), confinement is discussed in terms of an effective Sine-Gordon theory for the timelike component of the gauge field A_0. But whereas in the references above the fermion mass m is a Lagrangian parameter, we consider the m=0 case and ask whether an effective S-G theory can again be derived with m replaced by the dynamically generated mass Sigma which appears below T_{ch}, the critical temperature for the chiral phase transition. The fermion and gauge sectors are strongly interdependent, but as a first approximation we decouple them by taking Sigma to be a constant, depending only on the constant part of the gauge field. We argue that the existence of a low-temperature confining phase may be associated with the generation of Sigma; and that, analogously, the vanishing of Sigma for T > T_{ch} drives the system to its deconfining phase. The effect of the gauge field dynamics on mass generation is also indicated. (38kb)

description: For a set of realistic nucleon-nucleon potentials we evaluate microscopic parameters of binary collisions: a time duration of the scattering state, a mean distance and a rotation of nucleons during a collision. These parameters enter the kinetic equation as non-instantaneous and non-local corrections of the scattering integral, i.e., they can be experimentally tested. Being proportional to off-shell derivatives of the scattering T-matrix, non-instantaneous and non-local corrections make it possible to compare the off-shell behavior of different potentials in a vicinity of the energy shell. The Bonn one-Boson-exchange (A-C) and Paris potentials are found to yield very close results, while the separable Paris potential differs.

description: In this review we provide an introduction to the physics of a series of frustrated quantum rare-earth pyrochlores. We first give a background on the microscopic single- and two-ion physics of these materials, discussing the origins and properties of their exchange interactions and their minimal low-energy effective models, before outlining what is known about their classical and quantum phases. We then make use of this understanding to discuss four important material examples: Er$_2$Ti$_2$O$_7$, Yb$_2$Ti$_2$O$_7$, Tb$_2$Ti$_2$O$_7$ and Pr$_2$Zr$_2$O$_7$, covering in some detail what is known experimentally and theoretically for each, and summarize some key questions that remain open. Finally, we offer an outlook on some alternative material platforms for realizing similar physics and discuss what we see as prospects for future investigations on these quantum rare-earth pyrochlores.

description: We report the discovery of 31 new redshifted broad absorption line quasars (RSBALs) from the Sloan Digital Sky Survey (SDSS). The number of previously known such objects is 19. The identification of the new objects was enabled by calculating similarities between quasar spectra in the SDSS. Using these similarities we look for the objects that are similar to the ones in the original sample, visually inspecting only hundreds, out of over 160,000 spectra considered. We compare the performance of several similarity measures, as well as different methods of employing them, in finding the RSBALs. We find that decision tree based similarities recover the most objects, and that an ensemble of methods performs better than any single one. As the similarities are not tailored for the specific problem of finding RSBALs, they could be used for searching for other types of quasars. The similarities and the code for their calculation are available online.

description: The quantized form of the soft N=8 superconformal algebra is investigated. Its operator product expansions are shown to exhibit a one-parameter-class of (soft) anomalies, which may be arbitrarily shifted by certain suitable quantum corrections of the generators. In particular, the BRST operator can be constructed and made nilpotent in the quantum version of all known realizations of the algebra. This generalizes the results of Cederwall and Preitschopf, who studied the $\widehat{S^7}$-algebra, that is contained as a soft Kac-Moody part in the superconformal algebra. A Fock-space representation is given, that has to be somewhat unusual in certain modes.

description: Collective flow of Lambda hyperons in heavy ion reactions at SIS energies is investigated. It is found that a $Λ$ mean field constructed on the basis of the quark model leads to a good description of the experimental data of the in-plane transverse flow of $Λ$'s. The attractive mean field can also give rise to an additional "virtual" $Λ$ radial flow directed inwards, which is reflected by a "concave" structure of the transverse mass spectrum of the $Λ$ hyperons emitted at midrapidity. The $Λ$ radial flow is found to exhibit a strong mass dependence: The flow is visible in the Ni+Ni system, but is strongly reduced in the system of Au on Au.

description: Neutral diboson processes are precise probes of the Standard Model (SM) of particle physics, which entail high sensitivity to new physics effects. We identify in terms of dimension-8 effective operators the leading departures from the SM that survive in neutral diboson processes at high-energy, and which interfere with the unsuppressed SM helicity contributions. We describe symmetries and selections rules that single out those operators, both for weakly and strongly coupled physics beyond the SM. Finally, we show that unitarity and causality enforce, via dispersion relations, positivity constraints on the coefficients of these effective operators, reducing the parameter space which is theoretically allowed.

Spatial Geometry of Non-Abelian Gauge Theory in \(2 + 1\) Dimensions

Year: 1995

description: The Hamiltonian dynamics of \(2 + 1\) dimensional Yang-Mills theory with gauge group SU(2) is reformulated in gauge invariant, geometric variables, as in earlier work on the \(3 + 1\) dimensional case. Physical states in electric field representation have the product form \(Ψ_{\mathrm{phys}} [E^{a i}] = \exp ( i Ω[ E ] / g ) F [G_{ij}]\), where the phase factor is a simple local functional required to satisfy the Gauss law constraint, and \(G_{ij}\) is a dynamical metric tensor which is bilinear in \(E^{a k}\). The Hamiltonian acting on \(F [ G_{ij} ]\) is local, but the energy density is infinite for degenerate configurations where \(\det G (x)\) vanishes at points in space, so wave functionals must be specially constrained to avoid infinite total energy. Study of this situation leads to the further factorization \(F [G_{ij} ] = F_c [ G_{ij} ] \mathcal R [ G_{ij} ]\), and the product \(Ψ_c [E] \equiv \exp (i Ω[ E ] / g ) F_c [G_{ij}]\) is shown to be the wave functional of a topological field theory. Further information from topological field theory may illuminate the question of the behavior of physical gauge theory wave functionals for degenerate fields.

Time Evolution in the External Field: the Unitarity Paradox

Subjects: subject: High Energy Physics - Theory (hep-th)

description: One of the axioms of quantum field theory is the property of unitarity of the evolution operator. However, if one considers the quantum electrodynamics in the external field in the leading order of perturbation theory, one will find that the evolution transformation is a non-unitary canonical transformation of creation and annihilation operators. This observation was one of the arguments for the hypothesis that one should choose different representations of the canonical commutation relations at different moments of time in the exact quantum field theory. In this paper the contradiction is analyzed for the case of a simple quantum mechanical model being an analog of the leading order of the large-N field theory. On the one hand, this model is renormalized with the help of the constructive field theory methods; the Hilbert space and unitary evolution operator are constructed. On the other hand, the leading order of the evolution transformation in the strong external field is shown to be non-unitary. Thus, unitarity of evolution in the exact theory is not in contradiction with non-unitarity of the approximate theory.

Development and characterisation of elastomeric block copolymeric substrates for myocardial tissue engineering using embryonic stem cell derived cardiomyocytes
Creators: name: Jawad, Hedeer Zuhair
Publisher: name: Imperial College London
Year: 2009

description: Cardiac patches comprised of embryonic stem cell derived cardiomyocytes (ESC-CMs) attached to biodegradable polymeric substrates were developed for patients suffering from heart attacks. Cardiomyocytes were derived from mouse and human embryonic stem cell (ESC). Thermoplastic elastomeric (TPE) block co-polymers poly(ethylene terephthalate)/dilionic acid (PET/DLA), a relatively slow degrading biomaterial, served as substrates to deliver cardiomyocytes and to further support the myocardium after an infarct. Additionally, titanium dioxide (TiO2) nanoparticles (NPs) (mean size 23 nm), were incorporated in the PET/DLA polymer in a concentration of 0.2wt%. Results showed TiO2 NPs to effect polymer mechanical properties, increasing material stiffness and tensile strength. The surface roughness and hydrophilicity of the biomaterial also increased upon addition of TiO2 NPs. It was found that 0.2wt% TiO2 NP addition enhanced cellular adhesion, spread and proliferation. A fibroblastic cell line, used to test proliferation, proliferated on both biomaterials with and without pre-gelatin coating. Lactate dehydrogenase (LDH) release into culture media, used as a marker of cell death did not differ significantly between biomaterials and tissue culture plastic (TCP). The cytotoxicity of TiO2 NPs on adult cardiomyocytes, hESC-CMs and fibroblasts was also investigated at various concentrations (0-150 ppm) chosen based on their relevance for the intended application of the biomaterial. At 10 ppm the particles had no significant acute effect on cardiac contractility of either adult rat heart cells or hESC-CM. However, functional activity was significantly reduced, in terms of beating rate, over longer culture periods (4h). Further improvements were carried out to enhance the properties of the patch. The investigation included: i) lactide addition to the polymer to increase polymer degradation rate and ii) topographical surface changes introduced by a phase separation micromoulding technique (PSμM). Newly developed biomaterial was faster degrading (as measured by biomaterial %weight loss) and simultaneously encouraged fibroblast proliferation. Finally the biomaterials have been investigated ex vivo and in vivo by collaborators at NHLI (Imperial College London). The results have confirmed that the developed biomaterials in conjunction with cardiomyocytes from ESCs are promising for applications in myocardial tissue engineering (MTE) strategies with no adverse effect on cardiac functionality detected.

description: Stochastic Gradient Descent (SGD) based training of neural networks with a large learning rate or a small batch-size typically ends in well-generalizing, flat regions of the weight space, as indicated by small eigenvalues of the Hessian of the training loss. However, the curvature along the SGD trajectory is poorly understood. An empirical investigation shows that initially SGD visits increasingly sharp regions, reaching a maximum sharpness determined by both the learning rate and the batch-size of SGD. When studying the SGD dynamics in relation to the sharpest directions in this initial phase, we find that the SGD step is large compared to the curvature and commonly fails to minimize the loss along the sharpest directions. Furthermore, using a reduced learning rate along these directions can improve training speed while leading to both sharper and better generalizing solutions compared to vanilla SGD. In summary, our analysis of the dynamics of SGD in the subspace of the sharpest directions shows that they influence the regions that SGD steers to (where larger learning rate or smaller batch size result in wider regions visited), the overall training speed, and the generalization ability of the final model.
Modification of Dendritic Cells for the Induction of Tolerance
Creators: name: Khan, Adnan
Publisher: name: Imperial College London
Year: 2009

description: Allogeneic T cell stimulation requires not only antigen-specific signals but also costimulatory signals, most importantly between CD80/86 on the antigen presenting cell and CD28 or CTLA4 on the T cell. Engagement of the T cell receptor without costimulation can lead to anergy and the subsequent induction of regulatory T cells (Tregs). T cell activation is also controlled by dendritic cell (DC) expression of the tryptophan-catabolising, immunomodulatory enzyme indoleamine 2,3-dioxygenase (IDO). Depletion of this essential amino acid, and/or the production of tryptophan metabolites (kynurenines) inhibits T cell proliferation. With the aim of generating tolerogenic DCs for the induction of donor-specific transplantation tolerance, lentiviral vectors were used in this study for gene transfer into murine DCs. Firstly, an intracellular approach that prevents costimulation was developed: A fusion protein- CTLA4-KDEL- consisting of the extracellular domain of CTLA4 and the KDEL peptide [an endoplasmic reticulum (ER) retention signal] was expressed in DCs and prevented surface CD80/86 expression due to ER retention. A second approach used in the study involved the lentiviral gene transfer of IDO into DCs. The induction of donor-specific tolerance (mediated by Tregs with direct and indirect pathway allospecificity) was demonstrated, both in vitro and in vivo, using CTLA4-KDEL-expressing DCs. Linked suppression was observed and mediated by donor-specific Tregs. Although IDO-expressing DCs did not induce and/or sustain allogeneic T cell proliferation, this anergy lacked donor specificity. It was demonstrated that IDO+CD80/86+ DCs fail to induce and/or expand FoxP3+CTLA4+ Treg populations. Furthermore, IDO+CD80/86- DCs failed to sustain pre-induced populations of FoxP3+CTLA4+ Tregs (associated with a high rate of cell death). The capacity of CTLA4-KDEL- and IDO-expressing DCs to induce tolerance to allografts was investigated using a murine corneal allograft model, and administration of CTLA4-KDEL-expressing DCs prevented allograft rejection. The study demonstrates the clinical potential of CTLA4-KDEL-expressing DCs to induce Treg-mediated, donor-specific transplantation tolerance.

description: A kinetic equation which combines the quasiparticle drift of Landau's equation with a dissipation governed by a nonlocal and noninstantaneous scattering integral in the spirit of Enskog corrections is discussed. Numerical values of the off-shell contribution to the Wigner distribution, of the collision duration and of the collision nonlocality are presented for different realistic potentials. On preliminary results we show that simulations of quantum molecular dynamics extended by the nonlocal treatment of collisions leads to a broader proton distribution bringing the theoretical spectra closer towards the experimental values than the local approach.

Measuring well-being for public policy
Creators: name: Peasgood, Tessa May
Publisher: name: Imperial College London
Year: 2008

description: The aim of this thesis is to explore the most appropriate means of measuring individual wellbeing for public policy. The thesis will begin by asking exactly what is meant by well-being and giving a brief overview of the main philosophical accounts of well-being, summarising the variations within each account and considering how well-being can be measured from that perspective. Chapter Three uses analysis of the British Household Panel Survey (BHPS) to explore the differences between the well-being measures available within that dataset. This shows that, although in many cases the choice between different subjective well-being (SWB) measures appears to make minimal difference, there is wide variation between household income and subjective well-being measures and also some important cases where subjective measures differ. This implies that the choice of well-being measure will have important implications for policy making. To aid judgement between different well-being measures a list of criteria for an ideal measure of well-being to be used for public policy are set out in Chapter Four. Chapter Five asks how the various measures of well-being fare according to these criteria, finding that subjective measures perform at least as well, if not better, than existing measures of well-being drawn from neoclassical economic theory. The next three chapters use evidence from the SWB literature and additional analysis of the BHPS to asks whether our current understanding of the determinants of SWB is sufficient to support policy recommendations. Chapter six focuses on the relationship between income and SWB, specifically on evidence for inefficiencies arising from adaptation to income and reference income effects. Chapter seven looks at the relationship between SWB and social capital and considers the extent to which the relationship between talking to neighbours and SWB can be thought of as causal through the use of Instrumental Variable techniques. Lastly, chapter eight considers the role of SWB measures within microeconomic evaluation. The final chapter summarises the advantages and potential hurdles for the use of SWB indicators of wellbeing within public policy, concluding with recommendations for extending this work, both in relation to public policy and academic research.

description: Salt River Project (SRP) requested that Logan Simpson Design Inc. (LSD) perform a Class III cultural resources survey of a portion of the Arlington Wildlife Area (AWA), Maricopa County, Arizona. The project area is located on Arizona Game and Fish Department (AGFD) and private land on the west side of the Gila River. The project area includes a 33-ft-wide and 2,560-ft-long corridor centered on the main access road through private land and a 27.10-acre AGFD parcel that measures 2,360 ft north-south and 500 ft east-west. SRP is working coorperatively with AGFD on expanding and rehabilitating the wetlands for Yuma clapper rail habitat at AWA. Additionally, AGFD plans to minimally improve the main access road to AWA. The project area was partially surveyed to determine whether any cultural resources--prehistoric or historic archaeological sites or objects and potentially significant historic buildings or structures--exist that could be negatively affected by the proposed project. The project area is densely vegetated and it was not possible to access or survey a majority of the project area. A total of 7.5 acres of the project area was systematically surveyed. Becuase the project is located on state land under the jurisdication of AGFD, the cultural resources survey was completed in compliance with the requirements set forth in ARS § 41-861 et. Seq., the Arizona State Historic Preservation Act. An evaluation of Traditional Cultural Properties was not undertaken as part of this investigation.

description: In this letter we argue that instanton-dominated Green's functions in N=2 Super Yang-Mills theories can be equivalently computed either using the so-called constrained instanton method or making reference to the topological twisted version of the theory. Defining an appropriate BRST operator (as a supersymmetry plus a gauge variation), we also show that the expansion coefficients of the Seiberg-Witten effective action for the low-energy degrees of freedom can be written as integrals of total derivatives over the moduli space of self-dual gauge connections.

description: We introduce the concept of self-energy dispersion as an error bound on local theories and apply it to the two-dimensional Hubbard model on the square lattice at half-filling. Since the self-energy has no single-particle analog and is not directly measurable in experiments, its general behavior as a function of momentum is an open question. In this article we benchmark the momentum dependence with the Two-Particle Self-Consistent approach together with analytical and numerical considerations and we show that through the addition of a local single-particle potential to the Hubbard model the self-energy can be flattened, such that it is essentially described by only a frequency-dependent term. We use this observation to motivate that local theories, such as the dynamical mean-field theory, should be expected to give very accurate results in the presence of a potential of this kind. Finally, we propose a simple energy argument as an estimator for the crossover from non-local to local self-energies, which can be computed even by local theories such as dynamical mean-field theory.

description: We describe three previously unreported superconductors, BaPb3, Ba0.89Sr0.11Pb3 and Ba0.5Sr0.5Pb3. These three materials, together with SrPb3, form a distinctive isoelectronic family of intermetallic superconductors based on the stacking of Pb planes, with crystal structures that display a hexagonal to cubic perovskite-like progression, as rarely seen in metals. The superconducting transition temperatures (Tc) are similar for all - 2.2 K for BaPb3, 2.7 K for Ba0.89Sr0.11Pb3 and 2.6 K for Ba0.5Sr0.5Pb3, and the previously reported Tc of SrPb3, ~ 2 K, is confirmed. The materials are moderate coupling superconductors, and calculations show that the electronic densities of states at the Fermi energy are primarily contributed by Pb. The observations suggest that the Pb-stacking variation has only a minor effect on the superconductivity.

description: An archaeological testing program was undertaken for Salt River Project (SRP) on a parcel of private land being considered as a site for a future SRP substation. The project area, which lies near the prehistoric Hohokam village of Las Canopas (AZ U:9:46 [ASU]), totals about 2.6 acres, just over three percent of which was sampled with a combination of systematically and judgementally places backhoe trenches. No subsurface features were identified in any of the trenches, though a few prehistoric artifacts and charcoal were encountered. Archaeological clearance is recommended for the parcel.
Evolution of a selfish genetic element: the 2 micron plasmid of saccharomyces spp.
Creators: name: Harrison, Eleanor
Publisher: name: Imperial College London
Year: 2010

description: The 2 Micron plasmid is a multicopy DNA circle inhabiting the genome of the budding yeasts, Sacchormyces spp. The plasmid confers no known benefits to the host, but imposes a small fitness cost. However the plasmid is able to drive, i.e. to transmit to >50% of sexual offspring, which allows the element to spread through an outcrossing host population. Therefore we can consider the plasmid a selfish genetic element of yeast. Here we draw on a number of approaches to improve our understanding of this element. Firstly, we examined the relationship between the cost of plasmid carriage and copy number by experimentally manipulating the number of plasmids in the host. We find that host fitness decreases at a rate of ~0.09% per additional plasmid. Secondly we use experimentally evolving yeast populations to test the hypothesis that sexual reproduction, which is fundamental to the evolution of selfish genetic elements, will drive increasing virulence in the plasmid. We find that 2 Micron copy number increased in outcrossing populations but remained constant in asexual populations. We also find that sex allowed the invasion of non-functional mitochondria in to the populations, showing that sex has the capacity to generate a driving selfish genetic element from one of the most fundamental endosymbionts of the eukaryotic cell. In addition, we have investigated plasmid variation from global populations of Saccharromyces spp. in order to better understand the population biology and evolution of this plasmid. Here we find evidence that the plasmid is able to move between species, recombine with other plasmids within the cell, and exist at a surprisingly wide range of copy numbers in different host populations. Understanding the population structure and evolution of this element allows us to view the plasmid as an autonomous unit evolving in its own right in the genomes of its hosts.

description: Northland Research, Inc. (Northland) conducted a Class III archaeological survey of the proposed Salt River Project (SRP) Quail Substation expansion. Prior to the survey, an examination of site files maintained by the Arizona State Museum and the Arizona State Historic Preservation Office was conducted. No previously recorded sites were reported within two miles of the vicinity. The General Land Office maps, curated by the Phoenix office of the Bureau of Land Management, were examined prior to commencement of the fieldwork; no references to historic resources were noted. No archaeological remains were encountered by the survey, and Northland recommends that archaeological clearance be granted the proposed SRP Quail Substation expansion.

description: Entranco conducted archaeological testing at AZ U:9:226 (ASM) in Mesa, Maricopa County, between November 3, 2000 and March 5, 2001. The testing was completed to evaluate the eligibility of AZ U:9:226 (ASM) for inclusion in the National Register of Historic Places (NRHP). The project was conducted at the request of the Arizona Department of Transportation prior to the proposed construction of the Red Mountain Freeway (RMF), Gilbert Road to Higley Road segment. As discussed in this document, the RMF corridor encompasses the entire freeway right-of-way (R/W) and consists of areas that will be disturbed by construction of the freeway, and areas that will not be disturbed. The archaeological testing at AZ U:9:226 (ASM) was limited to the area of proposed construction impacts, and is referred to as the “project area” throughout this report. The portion of AZ U:9:226 (ASM) located outside of the project area, but within the R/W, will not be affected by the proposed construction and therefore was not tested. AZ U:9:226 (ASM) represents the reported location of T-9 (Gasser 1987) or Casas del Oriente (?) (Howard and Huckleberry 1991; Macnider et al. 1999; Mitchell 1988). T-9 and Casas del Oriente are two names that have been assigned to the large habitation site that is located on Turney’s 1929 map of prehistoric settlements in the Salt River Valley. Because modern surveys found this location to be covered with citrus orchards and disturbed by gravel mining operations, the testing was recommended to determine the site’s location, boundaries, and the nature and integrity of subsurface deposits prior to ground disturbing activities (Macnider et al. 1999). Testing at AZ U:9:226 (ASM) consisted of total station mapping and the systematic excavation of 227 backhoe trenches. Ten dispersed subsurface features were discovered, including eight pits that are possibly prehistoric, one historic pit, and one canal of undetermined age; two pieces of flaked stone, and a small amount of historic glass and metal artifacts were also recorded. In addition, a segment of the Old Consolidated Canal, designated as AZ U:9:228 (ASM), was identified and recorded within the project area.
$J/ψ$-Nucleon Scattering Length and In-medium Mass Shift of $J/ψ$ in QCD Sum Rule Analysis
Creators: name: Hayashigaki, Arata
Publisher: name: arXiv
Year: 1998
Subjects: subject: Nuclear Theory (nucl-th)

description: We calculate the spin-averaged $J/ψ$-nucleon scattering length $a_{J/ψ}$ by directly applying QCD sum rule to $J/ψ$-$N$ forward scattering amplitude. Our result $a_{J/ψ} = - 0.10 \pm 0.02$ fm, predicts the possibility of bound states with nuclei, though the force is weaker than that of the light vector mesons ($ρ,ω,ϕ$)-$N$ cases. Up to dimension-4 gluonic operators, we evaluate the scattering length with twist-2 contribution, which increases the absolute value of the scattering length about 30%. If we apply $a_{J/ψ}$ to the effective mass of $J/ψ$ in nuclear matter on the basis of the linear density approximation, it shows very slight decrease ($4 \sim 7$ MeV) at normal matter density.

Quadrupole Deformation of Barium Isotopes

description: The B(E2:0_1^+ -> 2_1^+) values of the Ba isotopes (Z=56) exhibit a sharp increase in deformation as the neutron numbers approach the mid-shell value of N=66. This behavior is anomalous because the 2_1^+ level energies are very similar to those of the neighboring isotopes. By means of the axially-symmetric deformed Woods-Saxon (WS) hamiltonian plus the BCS method, we investigated the systematics of B(E2) of the Ba isotopes. We showed that 15% of the B(E2) values at N=66 was due to the level crossing, occurring at the deformation with beta being nearly 0.3, between the proton orbits originating from the orbits Omega=1/2^-(h11/2) and 9/2^+(g9/2) at zero deformation. The latter of these two was an intruder orbit originating from below the energy gap at Z=50, rising higher in energy with the deformation and intruding the Z=50-82 shell. These two orbits have the largest magnitude of the quadrupole moment with a different sign among the orbits near and below the Fermi surface. Occupancy and non-occupancy of these orbits by protons thus affect B(E2:0_1^+ -> 2_1^+) significantly.

description: The growth of dust grains in protoplanetary disks is a necessary first step towards planet formation. This growth has been inferred via observations of thermal dust emission towards mature protoplanetary systems (age >2 million years) with masses that are, on average, similar to Neptune3. In contrast, the majority of confirmed exoplanets are heavier than Neptune. Given that young protoplanetary disks are more massive than their mature counterparts, this suggests that planet formation starts early, but evidence for grain growth that is spatially and temporally coincident with a massive reservoir in young disks remains scarce. Here, we report observations on a lack of emission of carbon monoxide isotopologues within the inner ~15 au of a very young (age ~100,000 years) disk around the Solar-type protostar TMC1A. By using the absence of spatially resolved molecular line emission to infer the gas and dust content of the disk, we conclude that shielding by millimeter-size grains is responsible for the lack of emission. This suggests that grain growth and millimeter-size dust grains can be spatially and temporally coincident with a mass reservoir sufficient for giant planet formation. Hence, planet formation starts during the earliest, embedded phases in the life of young stars.
