description: We discuss the evaluation of the real part of the elementary amplitudes in the context of a multiple diffraction model for $pp$ elastic scattering earlier developed. The framework is based on the concepts of analyticity and polynomial boundedness, and the techniques of dispersion relations. Novel results concern the use of derivative dispersion relations at the elementary level (constituent-constituent interactions) and an optimization of these relations in terms of one free parameter. In addition to a theoretical improvement, we achieved a satisfactory description of the physical quantities.

Increased contractile strength and tightened adhesions to the substratum result from reverse transformation of CHO cells by dibutyryl cyclic adenosine monophosphate

description: We have examined the changes in cellular contractility and adhesive morphology that accompany the reverse transformation of CHO cells caused by dibutyryl cyclic adenosine monophosphate. The ability of these cells to distort elastic silicone rubber substrata was found to increase markedly over the 5 h period following addition of cyclic AMP and testosterone to the medium, and to relax again following hormone removal. Parallel changes were observed in the interference reflexion image of the adhesion of these cells to glass substrata; broad grey-appearing 'close' contacts characteristic of the transformed state were gradually replaced by numerous small black-appearing 'focal contacts'. These changes in adhesive morphology required considerably longer (20-25 h) to be completed or to revert, however.
A New Vacuum-Operated Stress-Providing Instrument that Applies Static or Variable Duration Cyclic Tension or Compression to Cells in Vitro

description: An instrument providing cyclic stress to cells cultured in vitro has been developed. The unit uses a vacuum to deform a plastic Petri dish yielding 0.13% compression to cells on the inner surface, measured by strain gauge recordings. A regimen of 25 s stress and 5 min relaxation induced no significant change in synthesis of a 45 X 10(3) Mr protein that comigrates with actin, whereas a 52 X 10(3) Mr protein that comigrated with tubulin decreased from 12.7 +/- 0.451% of the total protein synthesized in control, static cells to 8.53 +/- 0.182% in stressed cells. The unit may have a broad application in monitoring biochemical changes in response to stress in cells such as muscle, lung, tendon, ligament and bone that are normally subjected to tension or compression.
Adhesion Plaques: Sites of Transmembrane Interaction between the Extracellular Matrix and the Actin Cytoskeleton

description: In this paper we review what is known about the organization of adhesion plaques, the regions where cells in culture adhere most tightly to the underlying substratum. These specialized areas of the plasma membrane serve as attachment sites for stress fibres. A major objective has been to determine how microfilament bundles are anchored at such regions. In their morphology and composition adhesion plaques resemble the adhesions fibroblasts make to the extracellular matrix. Some extracellular matrix components have been identified on the outside face of adhesion plaques. Within the plasma membrane of adhesion plaques, extracellular matrix receptors, such as the fibronectin receptor (integrin), have been identified. This transmembrane glycoprotein complex has been shown to bind the cytoplasmic protein talin, which, in turn, associates with vinculin. These proteins establish a transmembrane chain of attachment between the extracellular matrix and the cytoskeleton, although how the actin filaments interact with these components remains to be determined. Besides having a structural function, adhesion plaques may also be regions where regulatory signals are transmitted across the membrane. Consistent with this idea has been the finding that various tyrosine kinases and a calcium-dependent protease are concentrated at the cytoplasmic aspect of adhesion plaques. Furthermore, several adhesion plaque proteins become phosphorylated during cell transformation by Rous sarcoma virus. In future work it will be important to determine how such modifications affect the interactions of these proteins and the stability of adhesion plaques.

description: Resolving the relationship between biodiversity and ecosystem functioning has been one of the central goals of modern ecology. Early debates about the relationship were finally resolved with the advent of a statistical partitioning scheme that decomposed the biodiversity effect into a "selection" effect and a "complementarity" effect. We prove that both the biodiversity effect and its statistical decomposition into selection and complementarity are fundamentally flawed because these methods use a naïve null expectation based on neutrality, likely leading to an overestimate of the net biodiversity effect, and they fail to account for the nonlinear abundance-ecosystem functioning relationships observed in nature. Furthermore, under such nonlinearity no statistical scheme can be devised to partition the biodiversity effects. We also present an alternative metric providing a more reasonable estimate of biodiversity effect. Our results suggest that all studies conducted since the early 1990s likely overestimated the positive effects of biodiversity on ecosystem functioning.

description: Accurate determinations of the physical scale of a lattice action are required to check scaling and take the continuum limit. We present a high statistics study of the static potential for the SU(3) Wilson gauge action on coarse lattices ($5.54 \leq β\leq 6.0$). Using an improved analysis procedure we determine the string tension and the Sommer scale $r_0$ (and related quantities) to 1% accuracy, including all systematic errors. Combining our results with earlier ones on finer lattices, we present parameterizations of these quantities that should be accurate to about 1% for $5.6 \leq β\leq 6.5$. We estimate the $\La$-parameter of quenched QCD to be $\La_\MSb = 247(16)$ MeV.

description: We discuss rare kaon decays that violate charged-lepton flavour conservation in supersymmetric theories with and without R parity, in view of possible experiments using an intense proton source as envisaged for a neutrino factory. In the Minimal Supersymmetric Standard Model, such decays are generated by box diagrams involving charginos and neutralinos, but the limits from μ-> e γ, μ-e conversion and Δm_K constrain the branching ratios to challengingly small values. However, this is no longer the case in R-violating theories, where such decays may occur at tree level at rates close to the present experimental limits. Within this framework, we obtain bounds on products of LL\bar{E} and LQ\bar{D} operators from the experimental upper limits on K^0 -> μ^\pm e^\mp and K^{\pm,0} -> π^{\pm,0} μ^\pm e^\mp decays. We also note the possibility of like-sign lepton decays K^\pm -> π^\mp \ell^\pm \ell^\pm in the presence of non-zero \tilde{b}_L-\tilde{b}_R mixing. We conclude that rare kaon decays violating charged-lepton flavour conservation could be an interesting signature of R violation.

Cell Motility and the Problem of Anatomical Homeostasis
Creators: name: HARRIS, A. K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: The locomotion of tissue cells need not be invasive or disrupt normal tissue geometry, as occurs in cancer. The normal relationship between anatomical structure and cell locomotion is exactly the reverse, with motility serving to create and maintain the structures of the body. This relationship is most extreme in sponges, where time-lapse films show that the cells move about continually in patterns that restructure these animals' simple anatomy. The cells choose their position according to their differentiated cell type, which is the opposite of what is usually assumed to occur in development and has important implications for the functional significance of histotypic cell sorting. A particular type of cellular force that seems to be important in morphogenesis is the traction that all motile tissue cells exert. This traction can be studied by culturing cells on very thin sheets of silicone rubber, so that the locations and variations in the cellular forces are made visible by the wrinkles they produce in the rubber substratum. One finding has been that the traction forces exerted by untransformed fibroblasts are very much stronger than is needed for their own locomotion, but are well adapted for the function of rearranging and aligning collagen fibres to form structures like ligaments, tendons and muscles. These forces are found to be greatly weakened by neoplastic transformation, however, suggesting that malignant invasiveness results from some sort of deflection of cell traction forces from their proper morphogenetic functions, so as to produce uncontrolled invasion. To explain how motile cells create and maintain structures, as well as how their locomotion sometimes becomes perverted into the form of cancerous invasiveness, what seems to be needed is an extension of the concept of homeostasis to apply to the control of geometric relations between cells. This task may not be easy; one obstacle is the widespread belief that asymptotic stability implies the minimization of free energy. Instead, I suggest that stability results from balance of opposing forces within tissues, and that genes control which anatomical shapes will exist by determining the rules by which the relative strengths of these forces vary as functions of shape: to control shape, one must control the way forces vary with shape.
Chloral hydrate disrupts mitosis by increasing intracellular free calcium

description: In examining how chloral hydrate affects mitosis, we found that extracellular application of 0.1% chloral hydrate produced an abrupt rise in cytosolic free Ca2+. Digitized fluorescence microscopy of Fura-2-loaded, mitotic and interphase PtK cells revealed that Ca2+ rose 15 s after chloral hydrate application, peaked within 1 min at a concentration two- to sevenfold above the basal level and then slowly dropped. Bathing cells in 0.1% chloral hydrate caused metaphase spindles to shorten, starting in 1-2 min, and inhibited spindle elongation without affecting chromosome-to-pole movement during anaphase, as determined by phase-contrast observation of living cells. Spindle elongation and chromosome movement were unaffected by intracellular injection of 7.5% chloral hydrate. Extensive mitotic microtubule breakdown occurred after cells were bathed for 7 min in 0.1% chloral hydrate, while interphase microtubules were unaffected as determined by immunofluorescence. The chloral hydrate-induced microtubule breakdown and metaphase spindle shortening were prevented by 10 mM-CoCl2, which has previously been shown to block Ca2+ influx and to stabilize microtubules in vitro. These results imply that disruption of mitotic spindle function and structure by chloral hydrate is due to a rise in cytosolic free Ca2+, and also indicate that mitotic microtubules are more Ca2+-labile than interphase microtubules.

description: Polyclonal antisera raised against polypeptide components of antigenically related rat Sertoli cell secretory protein S70 and S45-S35 heterodimeric protein were used to identify antigenic sites in rat testis during spermatogenesis. Immunofluorescence, immunoperoxidase and immunogold electron-microscopic methods have shown that all antisera recognize immunoreactive sites in the acrosome of developing spermatids. Apical cytoplasmic regions of Sertoli cells in close association with bundles of developing spermatids displayed an immunoreactive product. The principal piece of the developing tail of maturing spermatids immunostained with antisera to Sertoli cell secretory S45-S35 heterodimeric protein, displayed characteristic apical-to-distal immunoreactive gradient patterns before acquiring uniform immunoreactivity at completion of maturation. Immunogold electron microscopy demonstrated that outer dense fibres were the predominant immunoreactive site. Results of this work, together with previous immunoblotting and immunofluorescent data, demonstrate that both Sertoli cell secretory proteins and components of the acrosome and tail of developing spermatids and epididymal sperm share antigenic homology.

description: NOMA is as a strong candidate for the Future Radio Access Network (FRA) due to its potential to support massive connectivity and high spectral efficiency. However, the most important drawback of NOMA is the error during Successive Interference Canceller (SIC) is implemented because of the inter-user interferences. In this paper, we derive closed-form exact Bit-Error Rate expressions for Downlink(DL) NOMA over Nakagami-m fading channels in the presence of SIC errors. The derived expressions are validated by the computer simulations. It is shown that the m parameter still represents the diversity order like as OMA systems. Besides, the BER performances of users for NOMA have substantially depended on the power allocation coefficient.

Culture patterns and sorting of rat Sertoli cell secretory proteins
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1988

description: A cocultivation chamber and two types of permeable substrates have been used to study: (1) the culture patterns of rat Sertoli and peritubular cells, and Sertoli cells cocultured with spermatogenic cells or peritubular cells; and (2) the polarized secretion of Sertoli cell-specific proteins transferrin, S70 and S45-S35 heterodimeric protein. Substrates included a nylon mesh (with openings of 100 micron) coated with extracellular matrix (ECM) material and an uncoated microporous filter (with pores of 0.45 micron). Sertoli cells cultured on ECM-coated nylon mesh organized a continuous sheet of multilayered epithelial cells essentially devoid of spermatogenic cells while peritubular cells formed a layer of squamous cells. Sertoli cells cultured on uncoated microporous substrate formed a continuous sheet of cuboidal epithelial cells with numerous basal cytoplasmic processes projecting into the substrate and abundant apically located spermatogenic cells, while peritubular cells organized one or two layers of loose squamous cells. [35S]methionine-labelled secretory proteins resolved by two-dimensional polyacrylamide gel electrophoresis and autoradiography displayed cell-specific patterns that were slightly influenced by the type of substrate. Sertoli cells cocultured with peritubular cells on uncoated microporous substrate under conditions that enabled separation of apical and basal surfaces, secreted proteins in a polarized fashion. While transferrin was released bidirectionally, S45-S35 heterodimeric protein was released apically. S70 was detected in both apical and basal compartments. We conclude from these studies that: (1) the number of spermatogenic cells decreases when Sertoli-spermatogenic cell cocultures are prepared on ECM-coated nylon substrate; and (2) Sertoli cells in coculture with spermatogenic or peritubular cells on uncoated microporous substrate, organize continuous sheets displaying polarized protein secretion.

description: A large lepton asymmetry in the Universe is still a viable possibility and leads to many interesting phenomena such as gauge symmetry nonrestoration at high temperature. We show that a large lepton asymmetry changes the predicted cosmic microwave background (CMB) anisotropy and that any degeneracy in the relic neutrino sea will be measured to a precision of 1% or better when the CMB anisotropy is measured at the accuracy expected to result from the planned satellite missions MAP and Planck. In fact, the current measurements already put an upper limit on the lepton asymmetry of the Universe which is stronger than the one coming from considerations of primordial nucleosynthesis and structure formation.

description: The conjunction of business and peace is a growing global phenomenon, but conducted and researched over a vast array of fields and contextual settings. This article provides theoretical order for this disparate material, illustrating cutting-edge research and highlighting the most urgent knowledge gaps to fill. Extracting findings from the business community, international organizations, and the academic community, this article maps these findings into five assertions about how businesses impact upon peace: economic engagement facilitates a peace dividend; encouraging local development facilitates local capacities for peace; importing international norms improves democratic accountability; firms can constrain the drivers or root causes of conflict; and undertaking direct diplomatic efforts with conflict actors builds and/or makes peace. These assertions provide a framework for categorizing and testing prominent business-peace arguments. They also support preliminary arguments that businesses cannot expect to be rewarded as peacebuilders just because they undertake peacebuilding activities, that economic opening only brings as much peace as a local regime will allow, and that truly courageous business-peace choices are rarely made in fragile contexts. This framework can encourage more coherent scholarly findings and more effective business engagements within the complex and challenging realm of peacebuilding.

description: Captive management of many wildlife species has proven to be challenging, with individuals displaying health disorders that are not generally described in the wild population. Retrospective studies have identified gastrointestinal (GI) diseases, in particular inflammatory bowel disease (IBD), as the second leading cause of captive adult red wolf (Canis rufus) mortality. Recent molecular studies show that imbalanced gut microbial composition is tightly linked to IBD in the domestic dog. The goal of the present study was to answer two main questions: (1) How do red wolf gut microbiomes differ among fecal consistency scores? and (2) How do red wolf gut microbiomes differ among diet types? Fresh fecal samples were collected from 53 captive wolves housed in eight facilities and from two wild wolves living in Alligator River National Wildlife Refuge. Each individual sample was given a fecal consistency score (FCS) as a iv proxy for GI health. Diet type was of interest due to the influence it can have on the gut microbiome. Gut microbiome composition from each sample was characterized using a targeted amplicon sequencing approach with the 16S rRNA gene. A higher relative abundance of the bacterial phylum Bacteroidetes was observed in samples obtained from captive wolves compared to the samples from wild wolves. Additionally, an increase in relative abundance of Bacteroidetes and a decreased relative abundance in Firmicutes was seen in red wolves with an FCS of 0 compared to wolves with an FCS of 2. In summary, there are differences in gut microbiome composition between a FCS of 0 and a FCS of 2 and among wild, whole meat, mixed and kibble diet types. Findings from this study increase the understanding of the interplay between diet and GI health in the red wolf, a critical piece of information needed to maintain healthy wolves in this captivity sustained species.

description: CoDEx is a Mathematica package that calculates the Wilson Coefficients (WCs) corresponding to effective operators up to mass dimension-6. Once the part of the Lagrangian involving single as well as multiple degenerate heavy fields, belonging to some Beyond Standard Model (BSM) theory, is given, the package can then integrate out propagators from the tree as well as 1-loop diagrams of that BSM theory. It then computes the associated WCs up to 1-loop level, for two different bases: "Warsaw" and "SILH". CoDEx requires only very basic information about the heavy field(s), e.g., Colour, Isospin, Hyper-charge, Mass, and Spin. The package first calculates the WCs at the high scale (mass of the heavy field(s)). We then have an option to perform the renormalisation group evolutions (RGEs) of these operators in "Warsaw" basis, a complete one (unlike "SILH"), using the anomalous dimension matrix. Thus, one can get all effective operators at the electro-weak scale, generated from any such BSM theory, containing heavy fields of spin: 0, 1/2, and 1. We have provided many example models (both here and in the package-documentation) that more or less encompass different choices of heavy fields and interactions. Relying on the status of the present day precision data, we restrict ourselves up to dimension-6 effective operators. This will be generalised for any dimensional operators in a later version.

description: We study the robustness of the quantization of the Hall conductivity in the Harper-Hofstadter model towards the details of the protocol with which a longitudinal uniform driving force $F_x(t)$ is turned on. In the vector potential gauge, through Peierls substitution, this involves the switching-on of complex time-dependent hopping amplitudes $\mathrm{e}^{-\frac{i}{\hbar}\mathcal{A}_x(t)}$ in the $\hat{\mathbf{x}}$-direction such that $\partial_t \mathcal{A}_x(t)=F_x(t)$. The switching-on can be sudden, $F_x(t)=θ(t) F$, where $F$ is the steady driving force, or more generally smooth $F_x(t)=f(t/t_{0}) F$, where $f(t/t_{0})$ is such that $f(0)=0$ and $f(1)=1$. We investigate how the time-averaged (steady-state) particle current density $j_y$ in the $\hat{\mathbf{y}}$-direction deviates from the quantized value $j_y \, h/F = n$ due to the finite value of $F$ and the details of the switching-on protocol. Exploiting the time-periodicity of the Hamiltonian $\hat{H}(t)$, we use Floquet techniques to study this problem. In this picture the (Kubo) linear response $F\to 0$ regime corresponds to the adiabatic limit for $\hat{H}(t)$. In the case of a sudden quench $j_y \, h/F$ shows $F^2$ corrections to the perfectly quantized limit. When the switching-on is smooth, the result depends on the switch-on time $t_{0}$: for a fixed $t_{0}$ we observe a crossover force $F^*$ between a quadratic regime for $FF^*$. The crossover $F^*$ decreases as $t_{0}$ increases, eventually recovering the topological robustness. These effects are in principle amenable to experimental tests in optical lattice cold atomic systems with synthetic gauge fields.

description: In this paper, error performance of the cooperative communication systems with the best relay selection scheme is investigated in the presence of error propagation from role to destination. The error propagation expression is derived firstly when the best relay is selected within M relays. The derived end-to-end BER expression is verified with the computer simulations. It is shown that the best relay selection does not ensure M+1 diversity order under the error propagation unlike perfect decoding. In addition, the threshold selection for the relays has dominant effect on the error performance of the system.

description: This manuscript explores the human capacities to look and to love and how that becomes complicated by death, my brother’s. The poems are meditations on these ideas, as well as what it means to be writing about them at all, to be communicating this from one body to another through the language of poems. I use the poem to talk to my brother and the reader. In some I use my brother’s language from Orphan song lyrics to create my own - an attempt to preserve something that is left of his voice and transform it into my own by way of my understanding of our relationship. Probably naturally, an obsession with measurement by means of observation builds as I search for how to understand a painful experience.

description: We systematically study the hadron longitudinal polarizations of the octet baryons at large $z$ from quark fragmentations in $e^+e^-$-annihilation, polarized charged lepton deep inelastic scattering (DIS) process, and neutrino (antineutrino) DIS process, based on predictions of quark distributions for the octet baryons in the SU(6) quark-spectator-diquark model and a perturbative QCD based counting rule analysis. We show that the $e^+e^-$-annihilation and polarized charged lepton DIS process are able to distinguish between the two different predictions of the hyperon polarizations. We also find that the neutrino/antineutrino DIS process is ideal in order to study both the valence content of the hyperons and the antiquark to hyperon (quark to anti-hyperon) fragmentations, which might be related to the sea content of hyperons.

Fibroblast contractility and actin organization are stimulated by microtubule inhibitors

description: Despite considerable evidence that cytoplasmic microtubules play some role in guiding or controlling the locomotion of tissue cells, the nature of this control is not understood. In particular, little is known about the role of microtubules in the exertion of propulsive 'traction' forces, or about microtubule effects on the organization of the cytoplasmic actin stress fibers. In this study, the silicone rubber substratum technique was used in combination with fluorescence microscopy in order to observe the effects of microtubule-depolymerizing drugs on the contractile strength and organization of cytoplasmic actin networks. Perfusion with a variety of microtubule poisons (either colcemid, nocodazole or vinblastine) was found to cause a rapid and substantial strengthening of fibroblast contractility. This was demonstrated in two established fibroblast cell lines, as well as in primary cultures of rat gingival fibroblasts and embryonic chick heart fibroblasts. Treatment with the drug taxol, which promotes microtubule assembly, was found to prevent the strengthening effects of the microtubule inhibitors. It was also found that the disruption of actin stress fibers by the phorbol ester tumor promoter, TPA, is reversed by microtubule poisons: stress fibers reform within 30 min of the addition of the microtubule drugs, despite the continued presence and activity of the TPA. Several possible mechanisms are considered, including the idea that microtubule assembly normally exerts a pushing force, which counterbalances part of the contractile force exerted by the actin stress fibers. However, the mechanism that seems best to account for the observations is that microtubules modulate, in an inhibitory fashion, the contractility and the state of organization of cytoplasmic actin.
Spin-Phonon coupling parameters from maximally localized Wannier functions and first principles electronic structure: the case of durene single crystal

description: Spin-orbit interaction is an important vehicle for spin relaxation. At finite temperature lattice vibrations modulate the spin-orbit interaction and thus generate a mechanism for spin-phonon coupling, which needs to be incorporated in any quantitative analysis of spin transport. Starting from a density functional theory \textit{ab initio} electronic structure, we calculate spin-phonon matrix elements over the basis of maximally localized Wannier functions. Such coupling terms form an effective Hamiltonian to be used to extract thermodynamic quantities, within a multiscale approach particularly suitable for organic crystals. The symmetry of the various matrix elements are analyzed by using the $Γ$-point phonon modes of a one-dimensional chain of Pb atoms. Then the method is employed to extract the spin-phonon coupling of solid durene, a high-mobility crystal organic semiconducting. Owing to the small masses of carbon and hydrogen spin-orbit is weak in durene and so is the spin-phonon coupling. Most importantly we demonstrate that the largest contribution to the spin-phonon interaction originates from Holstein-like phonons, namely from internal molecular vibrations.

description: We let S denote the ring of polynomial functions on the space of m x n matrices, and consider the action of the group GL = GL_m x GL_n via row and column operations on the matrix entries. For a GL-invariant ideal I in S we show that the linear strands of its minimal free resolution translate via the BGG correspondence to modules over the general linear Lie superalgebra gl(m|n). When I is the ideal generated by the GL-orbit of a highest weight vector, we give a conjectural description of the classes of these gl(m|n)-modules in the Grothendieck group, and prove that our prediction is correct for the first strand of the minimal free resolution.

description: We report the superconductivity in layered oxychalcogenide La2O2Bi3AgS6 compound. The La2O2Bi3AgS6 compound has been reported recently by our group, which has a tetragonal structure with the space group P4/nmm. The crystal structure of La2O2Bi3AgS6 can be regarded as alternate stacks of LaOBiS2-type layer and rock-salt-type (Bi,Ag)S layer. We measured low-temperature electrical resistivity and observed superconductivity at 0.5 K. The observation of superconductivity in the La2O2Bi3AgS6 should provide us with the successful strategy for developing new superconducting phases by the insertion of a rock-salt-type chalcogenide layer into the van der Waals gap of BiS2-based layered compound like LaOBiS2.

Lepto-hadronic $γ$-ray and neutrino emission from the jet of TXS 0506+056

description: The observation of IceCube-170922A event from the direction of TXS 0506+056 when it was in its enhanced $γ$-ray emission state offers a unique opportunity to investigate the lepto-hadronic processes in blazar jets. Here, the observed broadband emission of TXS 0506+056 is explained by boosted synchrotron/synchrotron self Compton emission from the jet whereas the $γ$-ray data observed during the neutrino emission- by inelastic interactions of the jet-accelerated protons in a dense gaseous target. The proton energy distribution is $\sim E_{p}^{-2.50}$, calculated straightforwardly from the data obtained by Fermi-LAT and MAGIC and if such distribution continues up to $E_{c,p}=10$ PeV, the expected neutrino rate is as high as $\sim0.46$ events during the long active phase of the source or $\sim0.15$ if the activity lasts 60 days. In this interpretation, the energy content of the protons above $>$ GeV in blazar jets can be estimated as well: the required proton injection luminosity is $\simeq2.0\times10^{48}\:{\rm erg\:s^{-1}}$ exceeding $10^3$ times that of electrons $\simeq10^{45}\:{\rm erg\:s^{-1}}$ which are in equipartition with the magnetic field. As the required parameters are physically realistic, this can be an acceptable model for explanation of the neutrino and $γ$-ray emission from TXS 0506+056.

description: We extend a previously developed description of the flavour parameters in the charged fermion sector, based on a U(2) flavour symmetry, to include two main features of the neutrino sector seemingly implied by recent data: a large mixing angle $θ_{μτ}$ and a large hierarchy in the neutrino squared mass differences. A unified description of quark and lepton masses and mixings emerges. The neatest quantitative predictions are for elements of the unitary mixing matrix in the lepton sector: |V_{μ1}| = |V_{e 3} / V_{μ3}| = |V_{e 2} / V_{τ3}| = \sqrt{m_e / m_μ}, which go together with the analogous relations in the quark sector: |V_{ub} / V_{cb}| = \sqrt{m_u / m_c}, |V_{td} / V_{ts}| = \sqrt{m_d / m_s}
