description: We model the cosmic medium as the mixture of a generalized Chaplygin gas and a pressureless matter component. Within a neo-Newtonian approach (in which, different from standard Newtonian cosmology, the pressure enters the homogeneous and isotropic background dynamics) we compute the matter power spectrum. The 2dFGRS data are used to discriminate between unified models of the dark sector (a purely baryonic matter component of roughly 5 percent of the total energy content and roughly 95 percent generalized Chaplygin gas) and different models, for which there is separate dark matter, in addition to that accounted for by the generalized Chaplygin gas. Leaving the corresponding density parameters free, we find that the unified models are strongly disfavored. On the other hand, using unified model priors, the observational data are also well described, in particular for small and large values of the generalized Chaplygin gas parameter $α$. The latter result is in agreement with a recent, more qualitative but fully relativistic, perturbation analysis in Gorini et al.

description: If the sparticles are relatively heavy (a few TeV) while the Higgs sector is not so heavy ($m_A$ is not so large), the Higgs boson Yukawa couplings can harbor sizable quantum effects of sparticles and these large residual effects may play a special role in probing supersymmetry at foreseeable colliders. In this work, focusing on the supersymmetric QCD effects in the hbb coupling (h is the lightest CP-even Higgs boson), we give a comparative study for the two popular supersymmetric models: the MSSM and NMSSM. While for both models the supersymmetric QCD can leave over large residual quantum effects in hbb coupling, the NMSSM can allow for a much broader region of such effects. Since these residual effects can be over 20% for the hbb coupling (and thus over 40% for the ratio $Br(h->bb)/Br(h->ττ)), future measurements may unravel the effects of heavy sparticles or even distinguish the two models.

Toward a theory of two-person interaction
Creators: name: Reimer, William C.
Publisher: name: University of British Columbia
Year: 2010

description: In this dissertation, a conceptual framework for the study of interaction between two persons is presented. One specific aspect of that framework is selected and an experimental test which focuses on that aspect is conducted. This test is designed to begin the process of refining the original conceptualization. The conceptual framework utilized stresses the sequential and information-processing features of interaction. The responses of persons are considered to be the result of two processes: one in which an interpretation is made (the "interpretive process"), and one by which that interpretation forms the basis for a new response (the "decision process"). This two-step model of action is used in order to deal with some of the problems created when a simple one-step behavioral model is used to deal with cognitive and linguistic processes. Since sequential interaction is a central concern in this dissertation, the manner in which interpretations or decisions are changed over time is a crucial issue. It is proposed that the "interpretive process" is best accounted for by a threshold type of operation, whereas the "decision process" might best be dealt with by a more simple learning model. These suggestions are made in order to account for some of the resistance to change which the literature on expectations identifies, and at the same time, the flexibility of response which is found in situations of learning. Once this conceptual framework is specified, a more detailed elaboration of the "interpretive process" is begun. Two general types of threshold choice processes are described: one which predicts a change in choice after a run of events of the same type, and the other which predicts a change after the differences between two event types reaches a threshold. An experiment is developed which allows one to differentiate which threshold model best accounts for the choices made. Thirty-five subjects are used and the results support the difference threshold model as the one which accounts for most of the choices. However, the predictive power of the difference model at its maximum is only 84% of the choices made. There is, in addition, some evidence which suggests that the subjects might alter choice models under certain conditions. Finally, several weak points in the conceptual framework are identified, along with suggestions regarding strategies for future research. Refinements of the experimental design which include greater controls on motivating and memory factors are suggested. Such refinements would allow an even stronger test of the threshold models proposed. An alternative suggestion is that the reseach move to an elaboration of the relationship between events and interpretations or an elaboration of the "decision process" itself.
Non-perturbative calculation of Z_m using Asqtad fermions

description: We report progress on a non-perturbative calculation of the light quark mass renormalization factor Z_m, using dynamical Asqtad fermions. This quantity is used to determine the light quark masses in the conventional MS-bar scheme. Such a non-perturbative determination of Z_m removes uncertainties due to truncation of its perturbative expansion, currently known to two loops. These calculations have been carried out using publicly available MILC lattices with spacings of approximately 0.125 and 0.09 fm.

description: We present a full quantum model to study the fidelity of single photons with different quantum states propagating in a medium exhibiting electromagnetically induced transparency (EIT). By using the general reservoir theory, we can calculate the quantum state of the transmitted probe photons that reveal the EIT phenomenon predicted by semiclassical theory while reflecting the influence of the quantum fluctuations of the strong coupling field. Our study shows that the coupling field fluctuations not only change the quantum state of the probe photons, but also slightly affect its transmittance. Moreover, we demonstrate that the squeezed coupling field can enhance the influence of its fluctuations on the quantum state of the probe photons, which means that the EIT effect can be manipulated by controlling the quantum state properties of the coupling field. The full quantum theory in this paper is suitable for studying quantum systems related to the EIT mechanism that would allow us to examine various quantum effects in EIT-based systems from a full quantum perspective.

Calcium related properties of plasma membranes from guinea pig placenta
Creators: name: Shami, Yehezkel
Publisher: name: University of British Columbia
Year: 2010

description: Calcium transport across the placenta is asymmetrical and is believed to be an active transport. An essential step in such a transport is translocation of the ion across a single plasma membrane. The objective of this thesis was to study the Ca2+ -related properties of the placental plasma membranes and to gain some knowledge of their role in Ca2+ -transport. Three Ca2+ -related properties were studied: 1. Ca2+ -binding to the placental plasma membranes; 2. The membrane bound enzyme Ca -ATPase; and 3. Ca2+ -uptake by the placental plasma membrane vesicles. Ca2+ -binding properties of the membrane preparation were studied by the use of a new method, the flow dialysis system. Two types of sites for Ca were found: 1) high affinity, low capacity sites, and 2) low affinity, high capacity sites. The high affinity sites had 10-fold higher affinity for Ca2+ than for Mg2+ . A calcium-stimulated, membrane-bound enzyme, namely Ca2+ -ATPase, was located in the placental plasma membranes. This enzyme is distinct from the Na+, K+-ATPase and alkaline phosphatase. The enzyme can be activated by Mg2+ but with lower efficiency. Both Ca2+ and Mg2+ activate the enzyme at the same site. A formula was derived, enabling one to predict very precisely the velocity of the enzyme incubated under any combination of Ca2+ and Mg2+ ; this relationship is presented in a three dimensional model. The formula can be used for other enzymes or other substrates, as was demonstrated with ATP and ADP. The placental plasma membrane vesicles are capable of accumulating Ca2+ . Ca2+ -uptake was defined as the amount of Ca2+ which is not available for rapid exchange and cannot be displaced by a high concentration of competitor in the presence of ATP. This definition is different from and more accurate than the one which is widely used and cited in the literature. An intravesicular Ca2+ concentration of 190 mM was recorded, which was 24-fold higher than the external Ca2+ concentration (8 mM). Ca2+ -uptake was dependent on ATP hydrolysis by the placental Ca2+ -ATPase. This process was independent of Mg2+ . It is suggested that while the substrate for Ca2+ -ATPase is Ca-ATP, the substrate for Ca2+ -uptake is Ca2+. The overall Ca2+ -related properties of the placental plasma membranes are independent of Mg and the entire process from binding to membrane through activation of the enzyme and finally Ca2+ -uptake is dependent on Ca2+ alone. This situation is unique to the placental plasma membranes. It is tempting to speculate that the link between the maternal and the fetal circulation is achieved by forming vesicles loaded with Ca2+ on the maternal side and unloading them through fusion with the basal plasma membrane on the fetal side. The Ca2+ -related properties of placental plasma membranes described in this thesis, provide many answers regarding the first step in the asymmetrical transplacental Ca2+ -transport. Further investigation is required before a full understanding of the entire process is achieved.

description: The modified gravitational equations to describe a four-dimensional braneworld in the case with the Lorentz invariant violation in a bulk spacetime is presented. It contains a trace part of the brane energy-momentum tensor and the coefficients of all terms describe the Lorentz violation effects from the bulk spacetime. As an application, we apply this formalism to study cosmology. In respect to standard effective Friedmann equations on the brane, Lorentz invariance violation in the bulk causes a modification of this equations that can lead to significant physical consequences. In particular, the effective Friedmann equation on the brane explicitly depends on the equation of state of the brane matter and the Lorentz violating parameters. We show that the components of five-dimensional Weyl curvature are related to the matter on brane even at low energies. We also find that the constraints on the theory parameters are depend on the equation of state of the energy components of the brane matter. Finally, the stability of the model depend on the specific choices of initial conditions and the parameters $β_i$.

description: A novel model of biological organisms is advanced, treating an organism as a self-consistent system subject to a pathogen flux. The principal novelty of the model is that it describes not some parts, but a biological organism as a whole. The organism is modeled by a five-dimensional dynamical system. The organism homeostasis is described by the evolution equations for five interacting components: healthy cells, ill cells, innate immune cells, specific immune cells, and pathogens. The stability analysis demonstrates that, in a wide domain of the parameter space, the system exhibits robust structural stability. There always exist four stable stationary solutions characterizing four qualitatively differing states of the organism: alive state, boundary state, critical state, and dead state.

description: Using numerical simulations based on solving the general relativistic hydrodynamic equations, we study the dynamics of a phase transition in the dense core of isolated rotating neutron stars, triggered by the back bending instability reached via angular momentum loss. In particular, we investigate the dynamics of a migration from an unstable configuration into a stable one, which leads to a mini-collapse of the neutron star and excites sizeable pulsations in its bulk until it acquires a new stable equilibrium state. We consider equations of state with softening at high densities, a simple analytic one with a mixed hadron-quark phase in an intermediate pressure interval and pure quark matter at very high densities, and a microphysical one that has a first-order phase transition, originating from kaon condensation. Although the marginally stable initial models are rigidly rotating, we observe that during the collapse (albeit little) differential rotation is created. We analyze the emission of gravitational radiation, which in some models is amplified by mode resonance effects, and assess its prospective detectability by interferometric detectors. We expect that the most favorable conditions for dynamic migration exist in very young magnetars. We find that the damping of the post-migration pulsations strongly depends on the character of the equation of state softening. The damping of pulsations in the models with the microphysical equation of state is caused by dissipation associated with matter flowing through the density jump at the edge of the dense core. If at work, this mechanism dominates over all other types of dissipation, like bulk viscosity in the exotic-phase core, gravitational radiation damping, or numerical viscosity.

Application of the Disk Evaporation Model to AGNs

description: The disk corona evaporation model extensively developed for the interpretation of observational features of black hole X-ray binaries (BHXRBs) is applied to AGNs. Since the evaporation of gas in the disk can lead to its truncation for accretion rates less than a maximal evaporation rate, the model can naturally account for the soft spectrum in high luminosity AGNs and the hard spectrum in low luminosity AGNs. The existence of two different luminosity levels describing transitions from the soft to hard state and from the hard to soft state in BHXRBs, when applied to AGNs, suggests that AGNs can be in either spectral state within a range of luminosities. For example, at a viscosity parameter, α, equal to 0.3, the Eddington ratio from the hard to soft transition and from the soft to hard transition occurs at 0.027 and 0.005 respectively. When the Eddington ratio of the AGN lies below the critical value corresponding to its evolutionary state, the disk is truncated. With decreasing Eddington ratios, the inner edge of the disk increases to greater distances from the black hole with a concomitant increase in the inner radius of the broad line region, $R_{BLR}$. The absence of an optically thick inner disk at low luminosities gives rise to region in the size of borad line-luminosity plane for which the relation $R_{BLR} \propto L^{1/2}$ inferred at high luminosities is excluded. As a result, a lower limit to the accretion rate is predicted for the observability of broad emission lines, if the broad line region is associated with an optically thick accretion disk. Thus, true Seyfert 2 galaxies may exist at very low accretion rates/luminosities. The differences between BHXRBs and AGNs in the framework of the disk corona model are discussed and possible modifications to the model are briefly suggested.

description: The reduced dynamics of two interacting qubits coupled to two independent bosonic baths is investigated. The one-excitation dynamics is derived and compared with that based on the resolution of appropriate non-Markovian master equations. The Nakajima-Zwanzig and the time-convolutionless projection operator techniques are exploited to provide a description of the non-Markovian features of the dynamics of the two-qubits system. The validity of such approximate methods and their range of validity in correspondence to different choices of the parameters describing the system are brought to light.

On the rate distortion function of Bernoulli Gaussian sequences

Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this paper, we study the rate distortion function of the i.i.d sequence of multiplications of a Bernoulli $p$ random variable and a gaussian random variable $\sim N(0,1)$. We use a new technique in the derivation of the lower bound in which we establish the duality between channel coding and lossy source coding in the strong sense. We improve the lower bound on the rate distortion function over the best known lower bound by $p\log_2\frac{1}{p}$ if distortion $D$ is small. This has some interesting implications on sparse signals where $p$ is small since the known gap between the lower and upper bound is $H(p)$. This improvement in the lower bound shows that the lower and upper bounds are almost identical for sparse signals with small distortion because $\lim\limits_{p\to 0}\frac{p\log_2\frac{1}{p}}{H(p)}=1$.

description: Our hypothesis is that the consolidation of the count's power and the new co-governance formulas associated with extended family, combined with the legal mechanisms of inheritance and marriage of the Visigothic law, allowed women from the county families to exercise power whether they were mothers, widows, wives or daughters. This process would reach its peak during the first half of the 11th century with the government of Ermesinde of Carcassonne, who was Countess of Barcelona. The first feudal wave during her government, which she firmly opposed, would give way to a new period of retrogression in the legal mechanisms that allowed women to access power. The changes brought forward by feudalism impacted the whole of society and led to a progressive disappearance of the old public mechanisms that guaranteed the Count’s power and authority and, in turn, negatively affected female participation in power and resulted in a more marked differentiation of gender roles.

description: We report CO(5$\rightarrow$4) and CO(6$\rightarrow$5) line observations in the dusty starbursting galaxy CRLE ($z = 5.667$) and the main-sequence (MS) galaxy HZ10 ($z = 5.654$) with the Northern Extended Millimeter Array (NOEMA). CRLE is the most luminous $z>5$ starburst in the COSMOS field and HZ10 is the most gas-rich "normal" galaxy currently known at $z>5$. We find line luminosities for CO(5$\rightarrow$4) and CO(6$\rightarrow$5) of (4.9 $\pm$ 0.5) and (3.8 $\pm$ 0.4) $\times$ 10$^{10}$ K km s$^{-1}$ pc$^{2}$ for CRLE and upper limits of $< 0.76$ and $< 0.60$ $\times$ 10$^{10}$ K km s$^{-1}$ pc$^{2}$ for HZ10, respectively. The CO excitation of CRLE appears comparable to other $z>5$ dusty star-forming galaxies (DSFGs). For HZ10, these line luminosity limits provide the first significant constraints of this kind for a MS galaxy at $z > 5$. We find the upper limit of $L'_{5\rightarrow4}/L'_{2\rightarrow1}$ in HZ10 could be similar to the average value for MS galaxies around $z\approx 1.5$, suggesting that MS galaxies with comparable gas excitation may already have existed one billion years after the Big Bang. For CRLE we determine the most likely values for the H$_2$ density, kinetic temperature and dust temperature based on excitation modeling of the CO line ladder. We also derive a total gas mass of $(7.1 \pm 1.3) \times 10^{10} M_\odot$. Our findings provide some of the currently most detailed constraints on the gas excitation that sets the conditions for star formation in a galaxy protocluster environment at $z > 5$.

Spectral Properties of Bright Fermi-detected Blazars in the Gamma-ray Band

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The gamma-ray energy spectra of bright blazars of the LAT Bright AGN Sample (LBAS) are investigated using Fermi-LAT data. Spectral properties (hardness, curvature and variability) established using a data set accumulated over 6 months of operation are presented and discussed for different blazar classes and subclasses: Flat Spectrum Radio Quasars (FSRQs), Low-synchrotron peaked BLLacs (LSP-BLLacs), Intermediate-synchrotron peaked BLLacs (ISP-BLLacs) and High-synchrotron peaked BLLacs (HSP-BLLacs). The distribution of photon index (obtained from a power-law fit above 100 MeV) is found to correlate strongly with blazar subclass. The change in spectral index from that averaged over the six month observing period is < 0.2-0.3 when the flux varies by about an order of magnitude, with a tendency toward harder spectra when the flux is brighter for FSRQs and LSP-BLLacs. A strong departure from a single power-law spectrum appears to be a common feature for FSRQs. This feature is also present for some high-luminosity LSP-BLLacs, and a small number of ISP-BLLacs. It is absent in all LBAS HSP-BLLacs. For 3C 454.3 and AO 0235+164, the two brightest FSRQ source and LSP-BLLac source respectively, a broken power law gives the most acceptable of power law, broken power law, and curved forms. The consequences of these findings are discussed.

Diagnosis. Male: Body of moderate-size (ca. 9 mm); slender. Antenna with more than 20 articles (23 in type species). Metacoxa without dorsal tooth; ventral surface of metafemur with three principal teeth, one blunt tooth near base, one larger blunt tooth near midlength, and one blunt tooth near apex, with seven minor, blunt teeth between principal teeth; tarsi pentamerous; pretarsal ungues simple; arolium present. Forewing with long, arched basal vein; vein Rs+M b absent; bullae absent; 2Cu a and 2Cu b present and tubular; 2A, 3A, and 2cu-a nebulous; hind wing with only Sc+ R present. First metasomal terga and sterna elongate, about five times longer than wide, but distinctly separate (not fused as in Stephaninae, such as Denaeostephanus Engel & Grimaldi, also in Baltic amber), thus forming “pseudo-petiole”, pseudo-petiole nearly as long as mesosoma; gaster slender, not distinctly thickened relative to pseudo-petiole, width gently tapering along its length. Female: Unknown. Etymology. The new genus-group name is a combination of Electrostephanus and an adjectival derivative of eidos (Greek, meaning, “kind” or “having the form of”). The name is masculine (while generic words ending in the noun eidos are neuter, those ending in the adjectival derivatives, such as – odes or – oides, may be in practice any gender [masculine, feminine, or neuter]: Brown, 1954).

description: Seigar, et al, have recently demonstrated a new, tight correlation between galactic central supermassive black hole (BH) mass and the pitch angle of the spiral arm in disc galaxies which they attribute to other indirect correlations. They fit a double power law, governed by five parameters, to the BH mass as a function of pitch. Noting the features of their fitted curve, we show that a simple linear proportion of the BH mass to the cotangent of the pitch angle can obtain the same fit, within error. Such a direct, elegant fit may help shed light on the nature of the correlation.

The Counts of Valentinois Beyond the Rhône: Territorial Dynamics, Power Networks and Communities of Inhabitants in Vivarais (13th-15th Centuries)

subject: Digital humanities
subject: Medieval history

description: Situated at the western end of the Kingdom of Burgundy, which had been attached to the Empire since the 11th century, the Vivarais is a border territory crossed by the presence of several actors with intertwined interests. If its borders are generally defined for the early Middle Ages from those of the diocese of Viviers, the creation of a bailliage in the 14th century and then of the particular States of Vivarais in the 15th century also concerned the ultra-Rhodanian areas of the dioceses of Valence and Vienne. In this context, the County of Valentinois formed a veritable principality at the beginning of the 13th century, whose power extended to both banks of the Rhône until the Poitiers family’s extinction in 1419. Through the study of the archives of this seigniory and of the lords and communities who paid tribute to it, this work aims to understand how their authority was structured and manifested on the right bank of the Rhône. The study of the dynamics that run through this space and the political interactions between the actors involved will make it possible to question the political unity that seems to have been built up during the period with the creation of the States. This work will also draw on broad contributions in digital humanities in order to study and represent the spatial dynamics and political networks that are apparent in the study of the sources.
The Digital Scholarly Edition of Paulinus Minorita's Compendium

description: I will propose a digital critical edition of Paulinus Minorita’s Compendium. The latter stands as one of the most original pieces of evidence regarding the growing interest in historiography within the Franciscan milieu during the 14th century. In fact, Paolinus authored three historiographical compilations: the Epithoma, the Compendium, and the Satirica Ystoria. These universal chronicles served as inspiration for later writers, including the doge-chronicler of Venice, Andrea Dandolo, and Giovanni Boccaccio.

description: We report neutron scattering measurements of the spinel oxide LiGaCr$_{4}$O$_{8}$, in which magnetic ions Cr$^{3+}$ form a breathing pyrochlore lattice. Our experiments reveal the coexistence of a nearly dispersionless resonance mode and dispersive spin wave excitations in the magnetically ordered state, which can be quantitatively described by a quantum spin model of hexagonal loops and linear spin wave theory with the same set of exchange parameters, respectively. Comparison to other Cr spinel oxides reveals a linear relationship between the resonance energy and lattice constant across all these materials, which is in agreement with our hexagonal loop calculations. Our results suggest a unified picture for spin resonances in Cr spinel oxides.

Interaction-tuned compressible-to-incompressible phase transitions in the quantum Hall systems

description: We analyze transitions between quantum Hall ground states at prominent filling factors $ν$ in the spherical geometry by tuning the width parameter of the Zhang-Das Sarma interaction potential. We find that incompressible ground states evolve adiabatically under this tuning, whereas the compressible ones are driven through a first order phase transition. Overlap calculations show that the resulting phase is increasingly well described by appropriate analytic model wavefunctions (Laughlin, Moore-Read, Read-Rezayi). This scenario is shared by both odd ($ν=1/3, 1/5, 3/5, 7/3, 11/5, 13/5$) and even denominator states ($ν=1/2, 1/4, 5/2, 9/4$). In particular, the Fermi liquid-like state at $ν=1/2$ gives way, at large enough value of the width parameter, to an incompressible state identified as the Moore-Read Pfaffian on the basis of its entanglement spectrum.

description: Proteine, die aus der natürlichen extrazellulären Matrix gewonnen werden, wie Gelatine, kommen in der klinischen Forschung zum Einsatz. Gewöhnlich wird Gelatine aus tierischem Material gewonnen, wodurch das Risiko einer pathogenen Übertragung und einer uneinheitlichen Produktqualität von Charge zu Charge besteht. Eine rekombinante Produktion in Hefe umgeht diese Nachteile, indem die Herstellung mit reproduzierbarer Qualität in tierkomponentenfreien Medien gewährleistet wird. Ein gelatinemimetisches Protein (GelMP), das auf der Alphakette des menschlichen Kollagen I basiert, wurde in Komagataella phaffii unter der Kontrolle des Promotors der Methanol-induzierbaren Alkoholoxidase (AOX1) geklont. Ein produzierender Klon wurde ausgewählt und die Produktion auf einen 30-L-Maßstab hochskaliert. Das GelMP wurde in das Kultivierungsmedium sekretiert, und die Endausbeute betrug 3,4 g/L. Das Zielprotein wurde direkt aus dem zellfreien Medium durch eine Cross-Flow Filtration gewonnen. Neben dem Gelatine- mimetischen Protein wurde ein Fibrin-basiertes Protein rekombinant hergestellt. Die Fibrinogen-γ-Kette (FGG) ist eine von drei Proteinketten, die das Blutgerinnungsprotein Fibrinogen bilden. FGG zeichnet sich durch interessante biologische Funktionen aus, wie z.B. die Bindung von Integrinen, Leukozyten, Thrombozyten, Fibroblasten, Endothelzellen und dem Wachstumsfaktor FGF-2. In dieser Arbeit wurde rekombinantes FGG als Biomaterial auf Fibrinbasis in Escherichia coli hergestellt. Die Gensequenz der menschlichen Fibrinogen γ - Kette wurde Codon optimiert, synthetisiert und in E. coli eingebracht. Das FGG wurde im 10 L Kultivierungsmaßstab als Inclusion bodies produziert. Die IBs wurden solubilisiert und mittels Zwei-Schritt-Chromatographie auf eine Reinheit von > 90 % aufgereinigt. In Zellkulturexperimenten förderte sowohl das rekombinante FGG als auch das Gelatine-mimetische Protein die Adhäsion und Proliferation von aus Fettgewebe gewonnenen mesenchymalen Stammzellen (AD-MSCs). Der funktionelle Unterschied ist von nativem Fibrinogen und tierischer Gelatine nicht zu unterscheiden. Das GelMP und FGG sind Alternativen zur Herstellung und Gewinnung von humanbasierten Strukturproteinen für den Einsatz in der regenerativen Medizin.

description: Love is one of the main – if not the main – themes in mediaeval literature. Despite this, love bears an ambiguous ontological situation and for this is often left undefined. The scholarly discussion is flawed by a persistent “intellectual malaise” that results from the “fragmentation due to specialisation” afflicting all the field. Its omnipresence allows me a new “distant reading” sort of strategy as a way to try to address the problem.

description: In this article, we study the ground-state mass of full-heavy tetraquarks $cc\bar c\bar c$ and $bb\bar b \bar b$ with solving the nonrelativistic four-body systems. The flux-tube configurations, the tetraquark four-body potential butterfly, and the dimeson potential flip-flop of SU(3) lattice quantum chromodynamics have been applied to describe the tetraquark interaction. Our numerical analysis indicates that the disconnected and connected static potentials can predict the mass of tetraquark very close to experimental data.
