description: In the current anthropogenic era characterised by human-induced environmental changes, long-term biomonitoring has become a crucial component for understanding ecological patterns and detecting shifts in biodiversity. However, spatiotemporal inconsistencies in biomonitoring efforts hinder transboundary progress in understanding and mitigating global environmental change effectively. The International Long-Term Ecosystem Research (ILTER) network is one of the largest standardised biomonitoring initiatives worldwide, encompassing 44 countries globally, including 26 European countries that are part of the European Long-Term Ecosystem Research network (eLTER). To better understand the establishment and development of such long-term biomonitoring efforts, we analysed spatial and temporal trends within the eLTER network. Additionally, we evaluated the environmental, social, and economic factors influencing engagement in biomonitoring activities within this European network. Our findings reveal a spatial imbalance, with biomonitoring efforts concentrated in Central and Western European countries, where monitoring initiatives have typically been established for a longer duration. Furthermore, our analyses underscore the complex interplay of economic, geographic, and cultural factors in the development of long-term ecological research infrastructures. Countries with greater geographic connectivity, slower economic growth, and higher research activity are more likely to be involved in the eLTER network. The intensity of biomonitoring significantly increased with greater research investments, economic growth, and elevated levels of tourism. In contrast, it decreased in countries that are more inward-facing and exhibit a belief in their ability to control environmental outcomes independently. Addressing spatial gaps in monitoring necessitates enhanced support and funding to ensure comprehensive ecological monitoring over extended time periods. This is essential for achieving transboundary sustainability and effective biodiversity conservation in the face of global change drivers.
Partial Yukawa unification and a supersymmetric origin of flavor mixing

description: In a large class of supersymmetric SO(10) and left-right models, requiring that the effective theory below the scale of $SU(2)_R$ breaking be the MSSM implies partial Yukawa unification with $Y_u=Y_d$ and $Y_e=Y_{ν^D}$. The same result also emerges in models with a horizontal $SU(3)_H$ symmetry. As a result, at the tree level, these models lead to vanishing quark mixing angles. We show that the correct mixing pattern can be generated in these models at the loop level from the flavor structure associated with the supersymmetry breaking terms. We generalize the constraints on supersymmetric parameters from flavor changing neutral current (FCNC) processes to include several squark mass insertions and confirm the consistency of the scheme. The expectations of this scheme for CP violating observables in the $B$ meson system are quiet different from the KM model, so it can be tested at the B factories.

Uridine kinase from Ehrlich ascites carcinoma. Purification and properties of homogeneous enzyme.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1985

description: Uridine kinase from Ehrlich ascites tumor cells has been purified about 60,000-fold to apparent homogeneity and with an overall recovery of about 40%. This purification was achieved using phosphocellulose and adenosine 5'-triphosphate-agarose affinity chromatography. The subunit molecular mass as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis was 31,000 daltons. With two-dimensional electrophoresis, only one spot was observed, indicating the absence of isoenzymes. Multiple peaks of activity are routinely observed on ion exchange chromatography or gel filtration, for both crude preparations or homogeneous uridine kinase, in agreement with our earlier results that this enzyme exists as multiple interconvertible oligomeric forms (Payne, R. C., and Traut, T. W. (1982) J. Biol. Chem. 257, 12485-12488). The purified enzyme has a specific activity of 283 mumol/min/mg of protein at 22 degrees C. Initial velocity studies using uridine and ATP are consistent with a sequential mechanism. Km values for uridine, cytidine, and ATP are 40, 57, and 450 microM, respectively. CTP and UTP are competitive inhibitors with respect to ATP, with Ki values for CTP and UTP of 10 and 61 microM, respectively. The enzyme was active with several nucleoside analogs, the Km values being 69 microM (5-fluorouridine), 200 microM (3-deazauridine), and 340 microM (6-azauridine). The pure enzyme is very sensitive to freezing, but can be maintained at O degrees C for 8 weeks with only 20% loss of activity. For long-term storage, enzyme in 50% glycerol can be maintained at -20 degrees C for many months with no detectable loss of activity.

description: Quarkonia, i.e. bound states of $b\bar{b}$ and $c\bar{c}$ quarks, are powerful observables to study the properties of nuclear matter under extreme conditions. The formation of a Quark-Gluon Plasma (QGP), which is predicted by lattice QCD calculations at high temperatures as reached at LHC energies, has a strong influence on the production and behavior of quarkonia. The latest ALICE results on bottomonium and charmonium production in nucleus$-$nucleus collisions are presented. This includes measurements of the $Υ$(1S) and $Υ$(2S) nuclear modification factors ($R_{\mathrm{AA}}$) at forward rapidity and the J/$ψ$ $R_{\mathrm{AA}}$ and $v_{2}$ as a function of centrality, $p_{\mathrm T}$ and rapidity in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV. Also, first results from J/$ψ$ measurements in Xe$-$Xe collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.44 TeV are presented. Further on, the experimental results are compared to various calculations from theoretical models.

description: The Anthropocene as a prospective new, ongoing series/epoch must be defensible against all relevant concerns. We address the seven, still-relevant challenges posed to the Anthropocene Working Group by the Chair, International Commission on Stratigraphy (ICS), in 2014. (1) Concept or reality? The Anthropocene possesses a substantial, sharply distinctive stratigraphic record recognisable through many proxy signals from the mid-20th century onwards; (2) GSSP or GSSA? The Anthropocene can be defined by a GSSP and correlated globally; (3) Past or future? The Anthropocene unquestionably represents geological time, its transformations having already moved the Earth System beyond Holocene norms towards an irreversible future trajectory; (4) Utility? The Anthropocene’s distinctive material content allows useful delineation on geological sections/maps; (5) Indelibility? Many of the Anthropocene’s transformative effects cannot be subsequently effaced or overprinted; (6) Fit within the Geological Time Scale (GTS)? The Anthropocene represents a unique, youngest, interval in Earth history and strata of profound significance; (7) What is its value? The chronostratigraphic Anthropocene has conceptual usefulness even informally, but would then lack the clarity, stability and recognition that formalization provides. Without its formalization, the GTS would no longer accurately reflect Earth history, diminishing the relevance of geological science for analysis of ongoing planetary change.
Nucleon-Nucleon Phase Shifts and Pairing in Neutron Matter and Nuclear Matter

description: We consider 1S0 pairing in infinite neutron matter and nuclear matter and show that in the lowest order approximation, where the pairing interaction is taken to be the bare nucleon-nucleon (NN) interaction in the 1S0 channel, the pairing interaction and the energy gap can be determined directly from the 1S0 phase shifts. This is due to the almost separable character of the NN interaction in this partial wave. Since the most recent NN interactions are charge-dependent, we have to solve coupled gap equations for proton-proton, neutron-neutron, and neutron-proton pairing in nuclear matter. The results, however, are found to be close to those obtained with charge-independent potentials.

description: A 1D model hamiltonian that is motivated by the recent discovery of the heavy-fermion behavior in the cuprates of the $Nd_2CuO_4$ type is studied. It consists of $t-J$ interacting conduction electrons coupled to a lattice of localized spins through a Kondo exchange term $J_K$. Exact diagonalization and density matrix renormalization group methods are used. The latter method is generalized to arbitrary densities. At half-filling, a spin gap opens for all $J_K>0$. Away from half-filling$,$ it is shown that, at strong $J_K$% , the ground state is an unsaturated ferromagnet . At weak $J_K$ the system is in a paramagnetic phase with enhanced RKKY correlations. The importance of self-screening of the local moments in the depletion regime is discussed. We argue that these findings transcend the specifics of the model.

Pheidole tepicana subsp. cavigenis Wheeler 1915b: 403.
Types Mus. Comp. Zool. Harvard.
Etymology L cavigenis, hollow cheek, significance unknown.
Diagnosis A member of the " pilifera complex" of the larger pilifera group; for a characterization of the complex, see under pilifera. P. cavigenis is distinguished within the complex by the following combination of traits.
Major: occiput and extensive dorsal surface anterior to the occiput rugoreticulate; a small patch of rugoreticulum is present just posterior to each antennal fossa; humerus very prominent and lobose in dorsal-oblique view; mesonotal convexity absent, but mesonotum descends abruptly to the metanotal groove; propodeal spines long and thin; postpetiole spinose. Minor: almost all of dorsal head surface longitudinally carinulate; propodeal spine needle-shaped. Measurements (mm) Major (Montezuma Pass, Arizona): HW 1.60, HL 1.86, SL 0.74, EL 0.22, PW 0.76. Minor: HW 0.62, HL 0.66, SL 0.62, EL 0.12, PW 0.40.
Color Major: body light reddish brown, mandibles and gaster plain medium brown. Minor: head and gaster medium brown, mesosoma and appendages light brown.
Range Known from several collections in the Huachuca Mts; thence west to Sycamore Canyon in the Pajarito Mts., about 20 miles west of Nogales (Stefan Cover). A series in the Museum of Comparative Zoology from Bocoyna, Chihuahua, belongs to this species but with some differences; it may represent a geographical variant.
biology According to Stefan Cover, who has collected intensively within the range of cavigenis, this species occurs in grassy gaps in juniper-oak-pinyon woodlands at mid-elevations. Nests are cryptic and seeds are sometimes found inside. Colonies appear to consist of no more than 200-300 individuals.

description: It is an old speculation that SU(N) gauge theory can alternatively be formulated as a string theory. Recently this subject has been revived, in the wake of the discovery of D-branes. In particular, it has been argued that at least some conformally invariant cousins of the theory have such a string representation. This is a pedagogical introduction to these developments for non-string theorists. Some of the existing arguments are simplified.

description: One decade after China's announcement of the Belt and Road Initiative (BRI), theoretical and practical debates linger about the environmental impacts. However, no studies have systematically analyzed how academic research conceptualizes BRI and sustainability within it. This study reviews definitional aspects and sustainability discourses concerning the BRI. Analyzing a sample of 171 peer-reviewed journal articles published between 2013 and 2024, the study uses a coding framework comprising eight categories broadly covering the sustainability building blocks of the BRI. Additionally, a comparison of academic conceptualizations and China's policy practices reveals several gaps on the topics of stakeholders, investment agencies, investment volumes, and sectors. Outdated or vague conceptualizations are found in research that examines (i) China as a unitary actor, (ii) the centrality of China-led organizations like the AIIB, and (iii) BRI investment volumes and impacts. Findings also reveal that scholarly knowledge about the BRI, a decade after the initiative's announcement, remains limited and disparate. The study's meta-framework advances the literature by providing a template for bringing sustainability studies and BRI studies together into more meaningful interface.
Chloroplast initiation factor 3 from Euglena gracilis. Identification and initial characterization.

description: A chloroplast ribosome dissociation factor (IF-3chl) has been identified in whole cell extracts of Euglena gracilis. This work represents the first report of an organellar ribosome dissociation factor. E. gracilis IF-3chl facilitates the dissociation of Escherichia coli ribosomes as demonstrated by sucrose density gradient analysis. Chloroplast IF-3 stimulates initiation complex formation on E. coli ribosomes with natural mRNA from the bacteriophage MS2. In addition, IF-3chl is effective in initiation complex formation with Euglena chloroplast or E. coli ribosomes in the presence of synthetic mRNA. IF-3chl is induced 12-fold by exposure of the cells to light. The chloroplast factor has been purified 30-fold by chromatography on DEAE-cellulose and phosphocellulose. The chromatographic properties of this factor differ considerably from those of prokaryotic ribosome dissociation factors.
Controllability of Social Networks and the Strategic Use of Random Information

description: This work is aimed at studying realistic social control strategies for social networks based on the introduction of random information into the state of selected driver agents. Deliberately exposing selected agents to random information is a technique already experimented in recommender systems or search engines, and represents one of the few options for influencing the behavior of a social context that could be accepted as ethical, could be fully disclosed to members, and does not involve the use of force or of deception. Our research is based on a model of knowledge diffusion applied to a time-varying adaptive network, and considers two well-known strategies for influencing social contexts. One is the selection of few influencers for manipulating their actions in order to drive the whole network to a certain behavior; the other, instead, drives the network behavior acting on the state of a large subset of ordinary, scarcely influencing users. The two approaches have been studied in terms of network and diffusion effects. The network effect is analyzed through the changes induced on network average degree and clustering coefficient, while the diffusion effect is based on two ad-hoc metrics defined to measure the degree of knowledge diffusion and skill level, as well as the polarization of agent interests. The results, obtained through simulations on synthetic networks, show a rich dynamics and strong effects on the communication structure and on the distribution of knowledge and skills, supporting our hypothesis that the strategic use of random information could represent a realistic approach to social network controllability, and that with both strategies, in principle, the control effect could be remarkable.

description: Glioma C62B cells were incubated for 18 h with [1-14C]arachidonic acid. Most (80%) of the added [1-14C] arachidonic acid was taken into the intracellular pool; less than 1% of the intracellular [1-14C]arachidonic acid remained unesterified; the rest was present in glycerophospholipids. Acetylcholine stimulation of the prelabeled cells resulted in the rapid accumulation of free [1-14C]arachidonic acid, presumably liberated by hydrolysis from phospholipids. Labeled unesterified [1-14C]arachidonic acid peaked by 90 s and returned to basal levels by 5 min. Paralleling the transient increase of unesterified [1-14C]arachidonic acid were increases in level of radioactivity in an unidentified lipoxygenase metabolite of arachidonic acid and of radioactive phosphatidic acid. The release of arachidonic acid induced by acetylcholine or carbachol was blocked by muscarinic but not nicotinic receptor antagonists; adrenergic or histaminergic receptor agonists were ineffective at stimulating arachidonic acid liberation. In contrast to the transient effects of stimulation with cholinergic agonists, stimulation with the divalent cation ionophore A23187 resulted in a linear increase in the accumulation of liberated arachidonic acid for at least 1 h. Furthermore, the pattern of metabolites synthesized from arachidonic acid in response to ionophore stimulation was more complex than that observed following cholinergic stimulation and included also several metabolites derived from cyclooxygenase activity. We conclude that muscarinic receptor agonists rapidly induce specific changes in arachidonic acid and phosphatidic acid metabolism in a glioma cell line and suggest that similar responses may occur in glial cells and play a physiologically significant role in neural metabolism.

description: A large Hilbert space is used for the calculation of the nuclear matrix elements governing the light neutrino mass mediated mode of neutrinoless double beta decay of Ge76, Mo100, Cd116, Te128 and Xe136 within the proton-neutron quasiparticle random phase approximation (pn-QRPA) and the renormalized QRPA with proton-neutron pairing (full-RQRPA) methods. We have found that the nuclear matrix elements obtained with the standard pn-QRPA for several nuclear transitions are extremely sensitive to the renormalization of the particle-particle component of the residual interaction of the nuclear hamiltonian. Therefore the standard pn-QRPA does not guarantee the necessary accuracy to allow us to extract a reliable limit on the effective neutrino mass. This behaviour, already known from the calculation of the two-neutrino double beta decay matrix elements, manifests itself in the neutrinoless double-beta decay but only if a large model space is used. The full-RQRPA, which takes into account proton-neutron pairing and considers the Pauli principle in an approximate way, offers a stable solution in the physically acceptable region of the particle-particle strength. In this way more accurate values on the effective neutrino mass have been deduced from the experimental lower limits of the half-lifes of neutrinoless double beta decay.

description: Following a novel approach, all known basic mass generation mechanisms consistent with an exact abelian U(1) gauge symmetry are shown to be related through an intricate network of dualities whatever the spacetime dimension. This equivalence which applies in the absence of any supersymmetry, is however restricted by the presence of topological terms generating possible topological effects. In particular in 3+1 dimensions the duality relations between the Maxwell-Higgs model, the Stueckelberg and the topological mass generation mechanisms are then established following a careful treatment of the gauge symmetry content. This result offers a new framework for an effective description of superconductivity or topological defects built from fields beyond the SM.

description: Quantum spin liquids (QSLs) have become a key area of research in magnetism due to their remarkable properties, such as long-range entanglement, fractional excitations, and topologically protected phenomena. Recently, the search for QSLs has expanded into the three-dimensional world, despite the suppression of quantum fluctuations due to high dimensionality. A new candidate material, K2Ni2(SO4)3, belongs to the langbeinite family and consists of two interconnected trillium lattices. Although magnetically ordered, it exhibits a highly dynamical and correlated state. In this work, we combine inelastic neutron scattering measurements with density functional theory (DFT), pseudo-fermion functional renormalization group (PFFRG), and classical Monte Carlo (cMC) calculations to study the magnetic properties of K2Ni2(SO4)3, revealing a high level of agreement between experiment and theory. We further reveal the origin of the dynamical state in K2Ni2(SO4)3 to be centred around a magnetic network composed of tetrahedra on a trillium lattice.

description: Using electron paramagnetic resonance spectrometry and the spin trap 5,5-dimethyl-1-oxide (DMPO), neutrophil free radical production in response to phorbol myristate acetate and opsonized zymosan was investigated. Using phorbol myristate acetate and zymosan (3 mg/ml), the superoxide spin-trapped adduct 2-2-dimethyl-5-hydroperoxy-1-pyrrolidinyloxyl (DMPO-OOH) and the hydroxyl spin-trapped adduct 2-2-dimethyl-5-hydroxy-1-pyrrolidinyloxyl (DMPO-OH) were detected. Only DMPO-OH was observed with zymosan (0.5 mg/ml). Hydroxyl radical production in the presence of dimethylsulfoxide (Me2SO) and DMPO yields 2,2,5-trimethyl-1-pyrrolidinyloxyl. The only 2,2-trimethyl-1-pyrrolidinyloxyl detected following neutrophil stimulation was that expected from DMPO-OOH degradation. Superoxide dismutase but not catalase inhibited generation of all three spin-trapped adducts. These data indicate that DMPO-OH arose from DMPO-OOH degradation and does not represent hydroxyl radical production. Under certain conditions DMPO-OH is the predominant spin-trapped adduct resulting from neutrophil superoxide production, perhaps due to cellular bioreduction of DMPO-OOH to DMPO-OH. Cytochalasin B, which prevents phagosome closure, inhibited zymosan-stimulated neutrophil oxygen consumption and electron paramagnetic resonance superoxide detection. No hydroxyl radical was detected. Spin trapping with DMPO appears to detect intraphagosomal free-radical formation.

description: A new model for hadronic string reinteractions based on a generalised area law is presented. The model describes both the hadronic final states in $e^+e^-$ annihilation and the diffractive structure function in deep inelastic scattering. The model also predicts a shift in the W-mass reconstructed from hadronic decays of W-pairs of the order 65 MeV.

description: Epidermal growth factor (EGF) binds to the extracellular domain of a specific 170,000-dalton transmembrane glycoprotein; this results in rapid removal of both ligand and receptor from the cell surface. In WB cells, a rat hepatic epithelial cell line, ligand-directed receptor internalization leads to receptor degradation. We tested whether the EGF receptor was replenished at a constitutive or enhanced rate following EGF binding by immunoprecipitating biosynthetically labeled EGF receptor from cells cultured with [35S]methionine. EGF stimulated receptor synthesis within 2 h in a dose-dependent manner; this was particularly evident when examining the nascent form of the receptor. To determine the site of EGF action, total WB cell RNA was transferred to nitrocellulose paper after electrophoresis and was hybridized to cDNA probes from both the external and cytoplasmic coding regions of the human EGF receptor. EGF increased receptor mRNA by 3-5-fold. Therefore, at least in some cells, the surface action of EGF that leads to EGF receptor degradation is counterbalanced by a positive effect on receptor synthesis.
Escherichia coli helicase II (urvD gene product) translocates unidirectionally in a 3' to 5' direction

description: Escherichia coli helicase II, product of the uvrD gene, is a single-stranded DNA-dependent nucleoside 5'-triphosphatase with helicase activity. As a DNA-dependent ATPase, helicase II translocates processively along single-stranded DNA (S. W. Matson, unpublished results). The direction of translocation has been determined using a helicase assay that directly measures the ability of helicase II to catalyze the displacement of a labeled DNA fragment from one end of a single-stranded linear DNA molecule. The translocation of helicase II along single-stranded DNA is unidirectional and in the 3' to 5' direction with respect to the DNA strand on which the enzyme is bound. A kinetic analysis of the displacement of a labeled DNA fragment annealed to a linear single-stranded DNA molecule is also consistent with unidirectional translocation in the 3' to 5' direction. These results are contrary to results previously obtained using an indirect helicase assay (Kuhn, B., Abdel-Monem, M., Krell, H., and Hoffmann-Berling, H. (1979) J. Biol. Chem. 254, 11343-11350).

description: We consider numerically the growth of neutrino asymmetry in active-sterile neutrino oscillations in the early universe. It is shown that the final sign of the asymmetry can be highly sensitive to small variations of the oscillation parameters. We find regions which are completely or partially chaotic, but also regions where the sign remains very robust. The consequences for atmospheric neutrino oscillations and primordial nucleosynthesis are then discussed. In the completely chaotic region the predicted He(4)-abundance has an inherent arbitrariness ΔY \simeq 0.01.

Pheidole vinelandica subsp. cerebrosior Wheeler 1915b: 405. Raised to species level by Creighton 1950a: 175.
types Amer. Mus. Nat. Hist.; Mus. Comp. Zool. Harvard.
Etymology Unknown.
Diagnosis A member of the " bicarinata complex" of the larger pilifera group; for a characterization of the complex, see under bicarinata.
P. cerebrosior is distinguished within the complex by the following combination of traits.
Major: postpetiole seen from above very wide and conulate; propodeal spines well-developed and backward-directed; pronotal humeri with short irregular carinulae.
Minor: mesosoma! pilosity comprises rows of evenly spaced pairs of erect hairs. Measurements (mm) Lectotype major: HW 1.12, HL 1.32, SL 0.60, EL 0.14, PW 0.58. Paralectotype minor: HW 0.46, HL 0.56, SL 0.44, EL 0.12, PW 0.28.
Color Major: body light reddish yellow, except for the gaster, which is a slightly contrasting yellowish brown. Minor: concolorous plain yellow.
Range Arizona and New Mexico, 550 to 1680 m; southern California, 950 m; Baja California, 640 m; Chihuahua, 1500 m (Creighton and Gregg 1955); numerous records by Stefan Cover (collection notes) and extreme southern Nevada (G. C. and J. Wheeler 1986g).
biology Creighton and Gregg (1955) report that the preferred habitat of cerebrosior is evergreen-oak-woodland in mountain canyons, with open desert less frequently occupied. The colonies are always small, and contain no more than 3 or 4 majors. Stefan Cover (unpublished specimen data) found numerous colonies in open Ephedra, mesquite, and mesquite-acacia desert, as well as riverine cottonwood forest, nesting variously under rocks beneath cow dung, and in open soil with multiple small crater nests. He found seed chambers in some nests and observed workers feeding on a dead beetle. A winged queen has been collected on 1 July. In Nevada, G. C. and Jeanette N. Wheeler (1986g) found a single colony under a half-buried stone in yucca-larrea desert.

description: In today’s ever-evolving scientific landscape, invasion science faces a plethora of challenges, such as terminological inconsistency and the rapidly growing literature corpus with few or incomplete syntheses of knowledge, which may be perceived as a stagnation in scientific progress. We explore the concept of ‘competency’, which is extensively debated across disciplines such as psychology, philosophy, and linguistics. Traditionally, it is associated with attributes that enable superior performance and continuous ingenuity. We propose that the concept of competency can be applied to invasion science as the ability to creatively and critically engage with global challenges. For example, competency may help develop innovative strategies for understanding and managing the multifaceted, unprecedented challenges posed by the spread and impacts of non-native species, as well as identifying novel avenues of inquiry for management. Despite notable advancements and the exponential increase in scholarly publications, invasion science still encounters obstacles such as insufficient interdisciplinary collaboration paralleled by a lack of groundbreaking or actionable scientific advancements. To enhance competency in invasion science, a paradigm shift is needed. This shift entails fostering interdisciplinary collaboration, nurturing creative and critical thinking, and establishing a stable and supportive environment for early career researchers, thereby promoting the emergence of competency and innovation. Embracing perspectives from practitioners and decision makers, alongside diverse disciplines beyond traditional ecological frameworks, can further add novel insights and innovative methodologies into invasion science. Invasion science must also address the ethical implications of its practices and engage the public in awareness and education programs. Such initiatives can encourage a more holistic understanding of invasions, attracting and cultivating competent minds capable of thinking beyond conventional paradigms and contributing to the advancement of the field in a rapidly changing world.
Large-basis shell-model calculation of 10C->10B Fermi matrix element

description: We use a $4\hbarΩ$ shell-model calculation with a two-body effective interaction derived microscopically from the Reid93 potential to calculate the isospin-mixing correction for the 10C->10B superallowed Fermi transition. The effective interaction takes into account the Coulomb potential as well as the charge dependence of T=1 partial waves. Our results suggest the isospin- mixing correction $δ_{C}\approx 0.1 %$, which is compatible with previous calculations. The correction obtained in those calculations, performed in a $0\hbarΩ$ space, was dominated by deviation from unity of the radial overlap between the converted proton and the corresponding neutron. In the present calculation this effect is accommodated by the large model space. The obtained $δ_{C}$ correction is about a factor of four too small to obtain unitarity of the Cabibbo-Kobayashi-Maskawa matrix with the present experimental data.

description: We consider techniques (based on an ultraviolet cutoff) used to prove that the pure boson ($ϕ^4)_4$ field theory is trivial and apply them instead to the dynamically generated quark-level linear sigma model. This cutoff approach leads to the conclusion that the latter field theory is in fact nontrivial.
