description: We derive an effective low-energy theory for metallic (armchair and non-armchair) single-wall nanotubes in the presence of an electric field perpendicular to the nanotube axis, and in the presence of magnetic fields, taking into account spin-orbit interactions and screening effects on the basis of a microscopic tight binding model. The interplay between electric field and spin-orbit interaction allows us to tune armchair nanotubes into a helical conductor in both Dirac valleys. Metallic non-armchair nanotubes are gapped by the surface curvature, yet helical conduction modes can be restored in one of the valleys by a magnetic field along the nanotube axis. Furthermore, we discuss electric dipole spin resonance in carbon nanotubes, and find that the Rabi frequency shows a pronounced dependence on the momentum along the nanotube.

description: The discovery of graphene in 2004 has sparked immense interest in atomically thin two-dimensional (2D) materials as well as the heterostructures made by vertically assembling different 2D layers, called van der Waals heterostructures. These van der Waals heterostructures facilitate an incredible level of control in an experimental setting by allowing the atomic species of each layer to be selected down to individual atoms. Additionally, new tuning parameters in van der Waals heterostructures, such as the relative twist angle, facilitate the development of long-range interference patterns known as moiré patterns. These moiré patterns can give rise to long range interactions and complicated electronic superstructures. For example, correlated states and superconductivity have been discovered in bilayers of graphene when the twist angle is tuned to specific “magic angles” such that flat bands emerge in the moiré pattern Brillouin zone. In addition to moiré patterns, interlayer interactions and proximity effects between the layers of van der Waals heterostructure provide a useful platform for manifesting novel physical phenomena and exciting application potential. In this work, I explore numerous aspects of van der Waal heterostructures, primarily through scanning tunneling microscopy and spectroscopy, and develop a novel sample fabrication technique that facilitates the surface probe studies of air-sensitive 2D van der Waals heterostructures.In this work, I first explore moiré patterns in semiconducting heterobilayers. While flat bands have been demonstrated to emerge in homobilayer systems when the twist angle is finely tuned, I show that flat bands can emerge in heterobilayers that are rotationally aligned. I proceed to analyze this system in the context of a smoothly varying potential generated by the moiré pattern and show that the model extends well to systems with non-zero misorientation. By incorporating mechanical deformation effects, a complete model is developed to understand the heterobilayer system and provide predictive capabilities for arbitrary semiconducting bilayer systems. Next, I explore the role of topology in heterostructures with WTe2. I show that the quantum spin Hall edge state persist in twisted homobilayers as long as the interlayer coupling is weak. Additionally, I demonstrate proximity-induced superconductivity in the quantum spin Hall edge state of monolayer 1T’-WTe2, which is a significant step towards realizing fault-tolerant topological superconductivity in a van der Waals material platform. Finally, I conclude with a study of graphene heterostructures where I show that band engineering holds promise for future device applications. Taken together, the results in this work demonstrate progress towards realizing application potential and insight into the next generation of electronic devices.

description: Wogonin (5, 7-Dihydroxy-8-methoxyflavone) is a traditional naturally occurring flavonoid derived from the root extract of Chinese medicine, named Scutellaria baicalensis Georgi. Wogonin contains various biological properties which include allergic diseases, anti-cancertherapy and anti-inflammatory activities. Wogonin also shows the effects of removing toxins and cleansing heat. Wogonin glycosides are known as wogonosides. Oroxindin, a wogonin glucuronide isolated from Oroxylum indicum, is one of the example of wogonoside. It is also used in Japanese herbal supplement named Sho-Saiko-To, as an important active ingredient. One of the major active constituents of wogonin, Scutellaria baicalensis, shows potent anticancer activities both in vivo and in vitro studies. The anticancer therapeutic activity of wogonin has been shown by regulation of different cell signaling pathways , which includes protein kinase B pathway (serine-threonine kinase) and AMP-activated protein kinase pathways. Wogonin also shows positive therapeutic anticancer effects in breast cancer by inhibiting the 5‑LO/BLT2/ERK/IL‑8/MMP‑9 signaling cascade and established a major pharmacological anticancer activity.

description: Liquid mixtures composed of colloidal particles and much smaller non-adsorbing linear homopolymers can undergo a gelation transition due to polymer-mediated depletion forces. We now show that the addition of linear polymers to suspensions of soft colloids having the same hydrodynamic size yields a liquid-to-gel-to-re-entrant liquid transition. In particular, the dynamic state diagram of 1,4-polybutadiene star-linear polymer mixtures was determined with the help of linear viscoelastic and small angle X-ray scattering experiments. While keeping the star polymers below their nominal overlap concentration, a gel was formed upon increasing the linear polymer content. Further addition of linear chains yielded a re-entrant liquid. This unexpected behavior was rationalized by the interplay of three possible phenomena: (i) depletion interactions, driven by the size disparity between the stars and the polymer length scale which is the mesh size of this entanglement network; (ii) colloidal deswelling due to the increased osmotic pressure exerted onto the stars; and (iii) a concomitant progressive suppression of depletion efficiency on increasing polymer concentration due to reduced mesh size, hence a smaller range of attraction. Our results unveil an exciting new way to tailor the flow of soft colloids and highlight a largely unexplored path to engineer soft colloidal mixtures.

description: The I3322 inequality is the simplest bipartite two-outcome Bell inequality beyond the Clauser-Horne-Shimony-Holt (CHSH) inequality, consisting of three two-outcome measurements per party. In case of the CHSH inequality the maximal quantum violation can already be attained with local two-dimensional quantum systems, however, there is no such evidence for the I3322 inequality. In this paper a family of measurement operators and states is given which enables us to attain the largest possible quantum value in an infinite dimensional Hilbert space. Further, it is conjectured that our construction is optimal in the sense that measuring finite dimensional quantum systems is not enough to achieve the true quantum maximum. We also describe an efficient iterative algorithm for computing quantum maximum of an arbitrary two-outcome Bell inequality in any given Hilbert space dimension. This algorithm played a key role to obtain our results for the I3322 inequality, and we also applied it to improve on our previous results concerning the maximum quantum violation of several bipartite two-outcome Bell inequalities with up to five settings per party.

description: We theoretically calculate the charge-supercurrent through a ballistic graphene junction where superconductivity is induced via the proximity-effect. Both monolayer and bilayer graphene are considered, including the possibility of strain in the systems. We demonstrate that the supercurrent at the charge neutrality point can be tuned efficiently by means of mechanical strain. Remarkably, the supercurrent is enhanced or suppressed relative to the non-strained case depending on the direction of this strain. We also calculate the Fano factor in the normal-state of the system and show how its behavior varies depending on the direction of strain.

description: The citation network of patents citing prior art arises from the legal obligation of patent applicants to properly disclose their invention. One way to study the relationship between current patents and their antecedents is by analyzing the similarity between the textual elements of patents. Many patent similarity indicators have shown a constant decrease since the mid-70s. Although several explanations have been proposed, more comprehensive analyses of this phenomenon have been rare. In this paper, we use a computationally efficient measure of patent similarity scores that leverages state-of-the-art Natural Language Processing tools, to investigate potential drivers of this apparent similarity decrease. This is achieved by modeling patent similarity scores by means of generalized additive models. We found that non-linear modeling specifications are able to distinguish between distinct, temporally varying drivers of the patent similarity levels that explain more variation in the data ($R^2\sim 18\%$) compared to previous methods. Moreover, the model reveals an underlying trend in similarity scores that is fundamentally different from the one presented previously.

description: In this paper, we investigate the complex dynamics of a spatial plankton-fish system with Holling type III functional responses. We have carried out the analytical study for both one and two dimensional system in details and found out a condition for diffusive instability of a locally stable equilibrium. Furthermore, we present a theoretical analysis of processes of pattern formation that involves organism distribution and their interaction of spatially distributed population with local diffusion. The results of numerical simulations reveal that, on increasing the value of the fish predation rates, the sequences spots $\rightarrow$ spot-stripe mixtures$\rightarrow$ stripes$\rightarrow$ hole-stripe mixtures holes$\rightarrow$ wave pattern is observed. Our study shows that the spatially extended model system has not only more complex dynamic patterns in the space, but also has spiral waves.

description: Weighted logic programming, a generalization of bottom-up logic programming, is a well-suited framework for specifying dynamic programming algorithms. In this setting, proofs correspond to the algorithm's output space, such as a path through a graph or a grammatical derivation, and are given a real-valued score (often interpreted as a probability) that depends on the real weights of the base axioms used in the proof. The desired output is a function over all possible proofs, such as a sum of scores or an optimal score. We describe the PRODUCT transformation, which can merge two weighted logic programs into a new one. The resulting program optimizes a product of proof scores from the original programs, constituting a scoring function known in machine learning as a ``product of experts.'' Through the addition of intuitive constraining side conditions, we show that several important dynamic programming algorithms can be derived by applying PRODUCT to weighted logic programs corresponding to simpler weighted logic programs. In addition, we show how the computation of Kullback-Leibler divergence, an information-theoretic measure, can be interpreted using PRODUCT.

description: Relativistic collisionless shocks are associated with efficient particle acceleration when propagating into weakly magnetized homogeneous media; as the magnetization increases, particle acceleration becomes suppressed. We demonstrate that this changes when the upstream carries kinetic-scale inhomogeneities, as is often the case in astrophysical environments. We use fully-kinetic simulations to study relativistic perpendicular shocks in magnetized pair plasmas interacting with upstream density perturbations. For amplitudes of $δρ/ρ\gtrsim 0.5$, the upstream fluctuations are found to corrugate the shock front and generate large-scale turbulent shear motions in the downstream, which in turn are capable of accelerating particles. This can revive relativistic magnetized shocks as viable energization sites in astrophysical systems, such as jets and accretion disks. The generation of large-scale magnetic structures also has important implications for polarization signals from blazars.

description: Recently, the use of Bessel beams in evaluating the possibility of using them for a new generation of GPR (ground penetrating radar) systems has been considered. Therefore, an analysis of the propagation of Bessel beam in conducting media is worthwhile. We present here an analysis of this type. Specifically, for normal incidence we analyze the propagation of a Bessel beam coming from a perfect dielectric and impinging on a conducting medium, i.e. the propagation of a Bessel beam generated by refracted inhomogeneous waves. The remarkable and unexpected result is that the incident Bessel beam does not change its shape even when propagating in the conducting medium.

For common $f$-divergences, i.e. functions which satisfy $f"(x)= ax^ γ,\, a>0, \, γ\in \mathbb R$, we give the conditions for the existence of corresponding $u_f$- maximising strategies, as well as explicit formulas.

description: We present a family-non-universal extension of the Standard Model where the the first two families feature both quark-lepton and electroweak-flavour unification, via the $SU(4) \times Sp(4)_L \times Sp(4)_R$ gauge group, whereas quark-lepton unification for the third family is realised à la Pati-Salam. Via staggered symmetry breaking steps, this construction offers a natural explanation for the observed hierarchical pattern of fermion masses and mixings, while providing a natural suppression for flavour-changing processes involving the first two generations. The last-but-one step in the symmetry-breaking chain is a non-universal 4321 model, characterised by a vector leptoquark naturally coupled mainly to the third generation. The stability of the Higgs sector points to a 4321$\to$SM symmetry-breaking scale around the TeV, with interesting phenomenological consequences in $B$ physics and collider processes that differ from those of other known 4321 completions.

description: The anxiety and trauma associated with the tragic coronavirus disease pandemic coded, COVID-19 led many to indulge in various unorthodox preventive measures such as the extensive indiscriminate use of alcohol-based hand sanitizers (ABHS), abuse, misuse, overdose of prescription drugs like chloroquine, hydroxychloroquine and chloroquine phosphate globally. While some preventive measures are recommended and adopted, such as national lockdown, self-isolation, quarantine, stay-at-home model, avoidance of large gathering, social distancing, wearing of face-masks and hand gloves, periodic hand washing particularly with liquid soaps/detergents under running tap water, avoidance of touching the face among others, the use of ABHS has been more prominent. ABHS contains on average 60-70 % by weight of one or more alcohols. During the 2019/2020 COVID-19 pandemic, the use of ABHS was more renowned to the extent that some individuals recommended the application on the hands every 30 minutes for a period of at least 20 seconds while outside the home. Though, the periodic application of the hand sanitizers seems like an effective on-the-go solution to preventing the spread of the virus, many other associated hazards call for caution. Besides transdermal absorption leading to mortality and morbidity of varying degree; alcohol-alcohol adulteration, deliberate and unintentional ingestion of ABHS may result in respiratory depression, irreversible blindness, intoxication, cirrhosis, acidosis, headache, central nervous system depression, seizure, hypoglycemia, coma, or even death in some cases. The non-ABHS are equally not absolutely safe as many of them contain active agents that are allegedly carcinogenic, toxic, inducing microbial resistance and endocrine disruption. Considered together, this implies that while some may not die from contracting the disease, the preventive measures taken could lead to death or other forms of morbidity thereby revealing that there is indeed, death in preventive measures when done without cautionary measures. This study seeks to highlight some associated risks in the use of ABHS and non-ABHS, whilst advocating the use of safer or ‘greener’ alternative procedure for use as preventive measures particularly during the COVID-19 pandemic.

description: The era of Gravitational-Wave (GW) astronomy will grant the detection of the astrophysical GW background from unresolved mergers of binary black holes, and the prospect of probing the presence of primordial GW backgrounds. In particular, the low-frequency tail of the GW spectrum for causally-generated primordial signals (like a phase transition) offers an excellent opportunity to measure unambiguously cosmological parameters as the equation of state of the universe, or free-streaming particles at epochs well before recombination. We discuss whether this programme is jeopardised by the uncertainties on the astrophysical GW foregrounds that coexist with a primordial background. We detail the motivated assumptions under which the astrophysical foregrounds can be assumed to be known in shape, and only uncertain in their normalisation. In this case, the sensitivity to a primordial signal can be computed by a simple and numerically agile procedure, where the optimal filter function subtracts the components of the astrophysical foreground that are close in spectral shape to the signal. We show that the degradation of the sensitivity to the signal in presence of astrophysical foregrounds is limited to a factor of a few, and only around the frequencies where the signal is closer to the foregrounds. Our results highlight the importance of modelling the contributions of eccentric or intermediate-mass black hole binaries to the GW background, to consolidate the prospects to perform precision cosmology with primordial GW backgrounds.

description: A common use of Markov Chains is the simulation of the seismic cycle in a fault, i.e. as a renewal model for the repetition of its characteristic earthquakes. This representation is consistent with Reid's elastic rebound theory. Here it is proved that in {\it any} one-way Markov cycle, the aperiodicity of the corresponding distribution of cycle lengths is always lower than one. This fact concurs with observations of large earthquakes in faults all over the world.
A hybrid CAD modeler for flexible geometric modeling of prismatic mechanical parts
Creators: name: Chen, Jack Szu-Shen
Publisher: name: University of British Columbia
Year: 2015

description: The ease and freedom of shape manipulation achievable through physical modeling materials such as clay for engineering design is steps beyond what is attainable through current computer-aided design (CAD) modelers. With the current CAD modeling paradigm, which creates models through a composition of features constrained by closed-form mathematical formulations, the flexibility in model shape manipulation is limited. As a result, many complex engineering shape designs are either completed in the physical regime then digitized or in the computer-graphics domain where modeling flexibility is significantly higher. Unfortunately, the gain in modeling flexibility is achieved at the expense of well-controlled feature information and modeling precision and accuracy. The resulting models are featureless inexact entities. In order to bring forth geometric modeling flexibility while retaining feature information along with modeling precision and accuracy, this thesis presents a novel hybrid CAD modeler. The hybrid modeler utilizes triangle mesh model representation with the notion of feature imposed as a separate but associated feature information layer. This allows the prismatic features on a model to be modified unrestrictedly without loss of feature information. Users can freely modify the model geometry beyond what is permissible by the current CAD modelers’ feature formulations/management. A robust feature segmentation scheme that divides a triangle mesh model into its elementary features automatically categorizes the unconstrained user modifications into prismatic features and updates the associated feature information layer. An idealization module completes the prismatic feature information extraction process and updates the mesh model to accurately reflect the newly detected/extracted features. Feature-based model editing is incorporated to permit accurate and precise feature-based editing and to maximize the ease-of-use of the hybrid modeler. Accordingly, the hybrid modeler consists of four modules: feature segmentation, feature idealization, unconstrained feature-free model modification and feature-based model editing. With the proposed hybrid modeler, modeling flexibility as well as precision and accuracy are satisfied simultaneously. The hybrid modeler provides the user with a flexible modeling environment for creating and modifying prismatic engineering design models.

The proposed 4-bit universal shift register increased the speed with low power consumption. The 4-bit universal shift register is designed and tested by using cadence virtuoso simulation tool in 180nm technology at a supply voltage of 1.8v for pulse latch and 2.5v for 4*1 MUX.

description: Recent observations of the galactic centers of M87 and the Milky Way with the Event Horizon Telescope have ushered in a new era of black hole based tests of fundamental physics using very long baseline interferometry (VLBI). Being a nascent field, there are several different modeling and analysis approaches in vogue (e.g., geometric and physical models, visibility and closure amplitudes, agnostic and multimessenger priors). We present \texttt{GALLIFRAY}, an open-source Python-based framework for estimation/extraction of parameters using VLBI data. It is developed with modularity, efficiency, and adaptability as the primary objectives. This article outlines the design and usage of \texttt{GALLIFRAY}. As an illustration, we fit a geometric and a physical model to simulated datasets using markov chain monte carlo sampling and find good convergence of the posterior distribution. We conclude with an outline of further enhancements currently in development.

description: We present a new definition of cosmic void and a publicly available code with the algorithm that implements it. Underdense regions are defined as free-form objects, called popcorn voids, made from the union of spheres of maximum volume with a given joint integrated underdensity contrast.The method is inspired by the excursion-set theory and consequently no rescaling processing is needed, the removal of overlapping voids and objects with sizes below the shot noise threshold is inherent in the algorithm. The abundance of popcorn voids in the matter field can be fitted using the excursion-set theory provided the relationship between the linear density contrast of the barrier and the threshold used in void identification is modified relative to the spherical evolution model. We also analysed the abundance of voids in biased tracer samples in redshift space. We show how the void abundance can be used to measure the geometric distortions due to the assumed fiducial cosmology, in a test similar to an Alcock-Paczyński test. Using the formalism derived from previous works, we show how to correct the abundance of popcorn voids for redshift-space distortion effects. Using this treatment, in combination with the excursion-set theory, we demonstrate the feasibility of void abundance measurements as cosmological probes. We obtain unbiased estimates of the target parameters, albeit with large degeneracies in the parameter space. Therefore, we conclude that the proposed test in combination with other cosmological probes has potential to improve current cosmological parameter constraints.

Development of innovative biosensors for the determination of melamine in milk
Creators: name: Hu, Yaxi
Publisher: name: University of British Columbia
Year: 2015

description: After discovering the potential detriment of melamine to humans, the society calls for novel techniques to accomplish accurate, rapid, high-throughput, and on-line or in-field detection of melamine in foods, as required by the food industry and government laboratories. The aim of this study was to investigate different innovative biosensors combining antibodies or molecularly imprinted polymers (MIPs) with surface enhanced Raman spectroscopy (SERS) to determine melamine in a representative dairy product (i.e. milk). A “two-step” antibody-SERS biosensor was developed to detect melamine in whole milk. The anti-melamine antibody, produced by immunizing New Zealand white rabbits with melamine hapten-ovalbumin immunogen, was used to extract melamine from whole milk exclusively. After releasing melamine from the antibody, the eluents were deposited onto silver dendrite SERS-active substrate for SERS spectral collection. The limit of detection (LOD) calculated by the principal component analysis (PCA) model was lower than 0.79×10-³ mmol/L. The overall analysis was completed in 20 min. The MIP for the “two-step” MIPs-SERS biosensor was synthesized by bulk polymerization of melamine, methacrylic acid, ethylene glycol dimethacrylate and 2,2’-azobisisobutyronitrile. After confirming the specific affinity of the MIP towards melamine by adsorption capacity tests, MIP was used as sorbent for solid phase extraction (SPE) to extract melamine from whole milk. SERS spectra were collected by depositing the eluents from MISPE onto silver dendrite. The LOD and limit of quantification (LOQ) calculated by the linear regression model correlating relative intensity of melamine SERS band at 703 cm-¹ and melamine concentration in whole milk were 0.012 mmol L-¹ and 0.039 mmol L-¹, respectively, and the full analysis was accomplished in 18 min. “One-step” MIPs-SERS biosensor incorporated silver nanoparticles (AgNPs) into MIPs synthesized by bulk polymerization. Adsorption capacity tests verified the specific affinity of MIPs-AgNPs to melamine, and PCA model resulted in the LOD between 0.01 and 0.017 mmol L-¹ melamine in skim milk. The time required to detect melamine in skim milk was 25 min. The low LOD and LOQ, as well as rapid detection confirm the potential of applying these three types of biosensors for accurate and high-throughput detection of melamine in dairy products.

description: We report spin-polarized transient absorption for colloidal CdSe nanoplatelets as functions of thickness (2 to 6 monolayer thickness) and core/shell motif. Using electro-optical modulation of co- and cross-polarization pump-probe combinations, we sensitively observe spin-polarized transitions. Core-only nanoplatelets exhibit few-picosecond spin lifetimes that weakly increase with layer thickness. Spectral content of differenced spin-polarized signals indicate biexciton binding energies that decrease with increasing thickness and smaller values than previously reported. Shell growth of CdS with controlled thicknesses, which partially delocalize the electron from the hole, significantly increases the spin lifetime to ~49 picoseconds at room temperature. Implementation of ZnS shells, which do not alter delocalization but do alter surface termination, increased spin lifetimes up to ~100 ps, bolstering the interpretation that surface termination heavily influences spin coherence, likely due to passivation of dangling bonds. Spin precession in magnetic fields both confirms long coherence lifetime at room temperature and yields excitonic g-factor.

description: Apigenin (4′,5,7-trihydroxyflavone) belongs to the group of flavonoids positioned on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one) and is most extensively allocated in herbs, vegetables, and fruits. Biosynthetically, apigenin is obtained from the phenylpropanoid pathway and also from the flavone synthesis pathway. The pathway of phenylpropanoid begins from the aromatic amino acids L-phenylalanine or L-tyrosine, both products of the shikimate pathway. In several recent studies, it has been shown that apigenin has a number of valuable bioactive functions, including antibacterial, antiviral, antiproliferative, anti-inflammatory, antioxidant, antiangiogenic, and anticancer activities. From the results of several in vivo and in vitro studies and clinical trials, apigenin has been shown to be an effective curative treatment for rheumatoid arthritis, autoimmune disorders, Parkinson’s disease, Alzheimer’s disease, and several types of cancers. Here, we summarize the key findings of the biological and pharmacological actions of apigenin.

description: Motivated by the recently proposed Kerr/CFT correspondence, we investigate the holographic dual of the extremal and non-extremal rotating linear dilaton black hole in Einstein-Maxwell-Dilaton-Axion Gravity. For the case of extremal black hole, by imposing the appropriate boundary condition at spatial infinity of the near horizon extremal geometry, the Virasoro algebra of conserved charges associated with the asymptotic symmetry group is obtained. It is shown that the microscopic entropy of the dual conformal field given by Cardy formula exactly agrees with Bekenstein-Hawking entropy of extremal black hole. Then, by rewriting the wave equation of massless scalar field with sufficient low energy as the SL(2, R)$_L$$\times$SL(2, R)$_R$ Casimir operator, we find the hidden conformal symmetry of the non-extremal linear dilaton black hole, which implies that the non-extremal rotating linear dilaton black hole is holographically dual to a two dimensional conformal field theory with the non-zero left and right temperatures. Furthermore, it is shown that the entropy of non-extremal black hole can be reproduced by using Cardy formula.

description: Random recursive hypergraphs grow by adding, at each step, a vertex and an edge formed by joining the new vertex to a randomly chosen existing edge. The model is parameter-free, and several characteristics of emerging hypergraphs admit neat expressions via harmonic numbers, Bernoulli numbers, Eulerian numbers, and Stirling numbers of the first kind. Natural deformations of random recursive hypergraphs give rise to fascinating models of growing random hypergraphs.

A direct proof of AGT conjecture at beta = 1

description: The AGT conjecture claims an equivalence of conformal blocks in 2d CFT and sums of Nekrasov functions (instantonic sums in 4d SUSY gauge theory). The conformal blocks can be presented as Dotsenko-Fateev beta-ensembles, hence, the AGT conjecture implies the equality between Dotsenko-Fateev beta-ensembles and the Nekrasov functions. In this paper, we prove it in a particular case of beta=1 (which corresponds to c = 1 at the conformal side and to epsilon_1 + epsilon_2 = 0 at the gauge theory side) in a very direct way. The central role is played by representation of the Nekrasov functions through correlators of characters (Schur polynomials) in the Selberg matrix models. We mostly concentrate on the case of SU(2) with 4 fundamentals, the extension to other cases being straightforward. The most obscure part is extending to an arbitrary beta: for beta \neq 1, the Selberg integrals that we use do not reproduce single Nekrasov functions, but only sums of them.
