description: We study the time evolution of a half-filled Hubbard layer coupled to a magnon bath after a quench of the Hubbard interaction. Qualitatively different regimes, regarding the asymptotic long-time dynamics, are identified and characterized within the mean-field approximation. In the absence of the bath, the dynamics of the closed system is similar to that of a quenched BCS condensate. Though the presence of the bath introduces an additional relaxation mechanism, our numerical results and analytical arguments show that equilibration with the bath is not necessarily attained within the approximations used. Instead, nonequilibrium states, similar to the ones observed in the closed system, can emerge at long times as a consequence of the competition between the intrinsic relaxation mechanism (Landau damping, for example), and the bath-induced dissipation.

description: Despite the recent success in data-driven fault diagnosis of rotating machines, there are still remaining challenges in this field. Among the issues to be addressed, is the lack of information about variety of faults the system may encounter in the field. In this paper, we assume a partial knowledge of the system faults and use the corresponding data to train a convolutional neural network. A combination of t-SNE method and clustering techniques is then employed to detect novel faults. Upon detection, the network is augmented using the new data. Finally, a test setup is used to validate this two-stage methodology on a centrifugal pump and experimental results show high accuracy in detecting novel faults.

description: Background: Many mathematical models have now been employed across every area of systems biology. These models increasingly involve large numbers of unknown parameters, have complex structure which can result in substantial evaluation time relative to the needs of the analysis, and need to be compared to observed data. The correct analysis of such models usually requires a global parameter search, over a high dimensional parameter space, that incorporates and respects the most important sources of uncertainty. This can be an extremely difficult task, but it is essential for any meaningful inference or prediction to be made about any biological system. It hence represents a fundamental challenge for the whole of systems biology. Results: Bayesian statistical methodology for the uncertainty analysis of complex models is introduced, which is designed to address the high dimensional global parameter search problem. Bayesian emulators that mimic the systems biology model but which are extremely fast to evaluate are embedded within an iterative history match: an efficient method to search high dimensional spaces within a more formal statistical setting, while incorporating major sources of uncertainty. The approach is demonstrated via application to two models of hormonal crosstalk in Arabidopsis root development, which have 32 rate parameters, for which we identify the sets of rate parameter values that lead to acceptable matches to observed trend data. The biological consequences of the resulting comparison, including the evaluation of gene functions, are described.

Activation of monogamy in non-locality using local contextuality

Year: 2016
Subjects: subject: Quantum Physics (quant-ph)

description: A unified view on the phenomenon of monogamy exhibited by Bell inequalities and non-contextuality inequalities arising from the no-signaling and no-disturbance principles is presented using the graph-theoretic method introduced in \textit{Phys. Rev. Lett. 109, 050404 (2012)}. We propose a novel type of trade-off, namely Bell inequalities that do not exhibit monogamy features of their own can be activated to be monogamous by the addition of a local contextuality term. This is illustrated by means of the well-known $\mathcal{I}_{3322}$ inequality, and reveals a resource trade-off between bipartite correlations and the local purity of a single system. In the derivation of novel no-signaling monogamies, we uncover a new feature, namely that two-party Bell expressions that are trivially classically saturated can become non-trivial upon the addition of an expression involving a third party with a single measurement input.

Hezhang Buyi: a highly endangered Northern Tai language with a Kra substratum
Creators: name: Hsiu, Andrew
Publisher: name: Zenodo
Year: 2017

description: Hezhang Buyi is a previously undocumented Northern Tai language that has absorbed elements of an unknown Kra language, which has left its effect on the phonology, lexicon, and syntax of Hezhang Buyi. Comparisons with a Buyi dialect of Jichang Township, Zhijin County, Guizhou that I had documented indicate that Hezhang Buyi is most closely related to Buyi dialects spoken just to the southeast of Hezhang County. “Hezhang Kra,” the substrate language of Hezhang Buyi, was likely to have been part of an extensive dialect chain of Kra lects that would have been spoken from northern Vietnam up to as far north as southeastern Sichuan, China. No exact classification within Kra can be deduced for Hezhang Kra, but it was likely in contact with Kra languages spoken in the far northwestern areas of Guizhou, including various Red Gelao lects and perhaps also Lachi. Field documentation of Hezhang Buyi is now more urgent than ever, with fewer than 10, or perhaps even fewer than 5, elderly speakers remaining. Although we can never revitalize this language, Hezhang Buyi contains vital clues to the ethnolinguistic history of western Guizhou and surrounding regions, as it is one of the “relict languages” of Guizhou being rapidly absorbed by Southwestern Mandarin. It is my sincere hope that we can see more of this language documented before it forever sinks into the shadows of unrecoverable history.

description: NB-Fi is a new low-power wide-area network technology, which has become widely used for smart cities, smart grids, the Industrial Internet of Things, and telemetry applications. Although many countries use NB-Fi, almost no papers study NB-Fi, and its peak performance is unknown. This article aims to fill this gap by analyzing this technology and studying the problem of rate assignment in NB-Fi networks. For that, this article develops a mathematical model used to find the packet loss ratio, packet error rate, and the average delay for various rate assignment approaches. The performance evaluation results are used to develop the guidelines for NB-Fi configuration to optimize the network performance.

description: Furniture is commonly perceived according to its functional role as a work surface, storage vessel, and architectural device designed to support the physical needs of the body in navigating everyday tasks. In the case of disasters such as seismic events, however, furniture invites alternative roles. For instance, we are instructed to “duck, cover, and hold” beneath a table in order to avoid injury from falling debris, and thus, in this context, a table undergoes an instantaneous transformation into a shelter. In the case of distressing events such as earthquakes, while our physical needs are considered, our psychological needs are seemingly ignored. This article presents a case study of speculative furniture designs that expand upon and challenge the traditional role of furniture by prioritizing the mitigation of anxiety over physical functionality. In an aim to promote psychological resilience around the anticipatory and residual stress that we encounter in our everyday lives, these designs apply empathy, humor, and play to elicit positive emotional responses. By capitalizing on the unique sensory-rich interactions afforded by furniture, this research proposes an unconventional yet valuable strategy in fostering meaningful, object-centered relationships.

description: We experimentally demonstrate the Talbot effect resulting from the repeated self-reconstruction of a spatially intensity-modulated probe field under the Fresnel near-field regime. By launching the probe beam into an optically induced atomic lattice (established by interfering two coupling fields) inside a rubidium vapor cell, we can obtain an diffracted probe beam pattern from an formed electromagnetically induced grating (EIG) in a three-level $Λ$-type Doppler-free atomic configuration with the assistance of electromagnetically induced transparency (EIT). The EIG-based diffraction pattern repeats itself at the planes of integer multiple Talbot lengths, which agrees well with the theoretical prediction [Appl. Phys. Lett., 98, 081108 (2011)]. In addition, fractional EIT-induced Talbot effect was also investigated. Such experimentally demonstrated EIT Talbot effect in a coherently-prepared atomic system may pave a way for lensless and nondestructive imaging of ultracold atoms and molecules, and further demonstrating nonlinear/quantum beam dynamical features predicted for established periodic optical systems.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Dirac equation in Newman-Penrose formalism is comprehensively introduced to prove the non-existence of bound states for ω < me in Schwarzschild geometry. The proof by contradiction is drawn in the context of finding polynomial solutions for the generalized Heun equation, thus the solutions are resonant states decaying over time. This work is divided into five parts. The first part is about the Dirac equation and the circumstances in which this equation emerged. Followed by two brief subsections on the mathematical substratum of the Dirac equation and its solution, i.e., Dirac algebra and Dirac spinor respectively. For the sake of elaborating on the mathematical tools used in this subject, the second part consists of a brief motivation for the general theory of relativity and its mathematical methods. The third part is dedicated to treating the Dirac equation in a more advanced mathematical framework, the Newman-Penrose formalism, which is a special case of the tetrad formalism of general relativity. The proof is elaborated in part 4, followed by conclusions in the fifth part.

description: Holographic theories with a local gravitational dual have a number of striking features. Here I argue that many of these features are controlled by the Eguchi-Kawai mechanism, which is proposed to be a hallmark of such holographic theories. Higher-spin holographic duality is presented as a failure of the Eguchi-Kawai mechanism, and its restoration illustrates the deformation of higher-spin theory into a proper string theory with a local gravitational limit. AdS/CFT is used to provide a calculable extension of the Eguchi-Kawai mechanism to field theories on curved manifolds and thereby introduce "topological volume independence." Finally, I discuss implications for a general understanding of the extensivity of the Bekenstein-Hawking-Wald entropy.

title: Iron and Infection: Neonatal Iron Transition
Creators: name: Cross, JH
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2020

description: Neonates, particularly those born preterm (PTB) and low birthweight (LBW), are especially susceptible to bacterial infections that cause an estimated 225,000 deaths annually. Iron is a vital substrate for the most common organisms causing septicaemia. Full-term babies elicit an immediate post-natal hypoferremia assumed to have evolved as an innate defence. This thesis aimed to test whether preterm and low birthweight newborns are capable of a similar response. A longitudinal observational study was conducted in 430 hospital-delivered Gambian babies. Demographic, anthropometric and haematological data were collected from 152 babies who were either PTB (between ≥32-<37 weeks gestational age) and/or LBW (<2500g) (PTB/LBW) and 278 full-term, normal-weight babies (FTB/NBW). Blood was sampled from the umbilical cord and matched venous blood samples from all neonates between 6-24 hours after delivery. An additional matched venous blood sample was taken from all full-term, normal birth weight newborns between 24-192 hours of life. In both FTB/NBW and PTB/LBW neonates, serum iron decreased 3-fold compared to umbilical blood concentrations within 12h of delivery (23·3±0·35 vs 7·5±0·22 ng/ml, P<0.001, n=425). Hepcidin levels doubled (27·0±0·96 vs 52·9±1·63 ng/ml, P<0·001, n=425). In FTB/NBW neonates, a steady increase in serum iron and TSAT follows (to 16.5±3.9μmol/L and 36.7±9.2% respectively by 136-192hrs postdelivery), even in the presence of relatively high serum hepcidin levels (45.2±19.1ng/ml) suggestive of hepcidin resistance possibly caused by iron saturation of macrophages. Our findings confirm that a very rapid hypoferremia occurs in the early hours of post-natal life with evidence that it is mediated by an increase in hepcidin. The strength and consistency of this effect in all neonates indicates that it may have evolved as an innate immune response designed to protect newborns from bacterial septicaemia.

description: Background: View planning for the acquisition of cardiac magnetic resonance (CMR) imaging remains a demanding task in clinical practice. Purpose: Existing approaches to its automation relied either on an additional volumetric image not typically acquired in clinic routine, or on laborious manual annotations of cardiac structural landmarks. This work presents a clinic-compatible, annotation-free system for automatic CMR view planning. Methods: The system mines the spatial relationship, more specifically, locates the intersecting lines, between the target planes and source views, and trains deep networks to regress heatmaps defined by distances from the intersecting lines. The intersection lines are the prescription lines prescribed by the technologists at the time of image acquisition using cardiac landmarks, and retrospectively identified from the spatial relationship. As the spatial relationship is self-contained in properly stored data, the need for additional manual annotation is eliminated. In addition, the interplay of multiple target planes predicted in a source view is utilized in a stacked hourglass architecture to gradually improve the regression. Then, a multi-view planning strategy is proposed to aggregate information from the predicted heatmaps for all the source views of a target plane, for a globally optimal prescription, mimicking the similar strategy practiced by skilled human prescribers. Results: The experiments include 181 CMR exams. Our system yields the mean angular difference and point-to-plane distance of 5.68 degrees and 3.12 mm, respectively. It not only achieves superior accuracy to existing approaches including conventional atlas-based and newer deep-learning-based in prescribing the four standard CMR planes but also demonstrates prescription of the first cardiac-anatomy-oriented plane(s) from the body-oriented scout.

Variational quantum algorithms for Poisson equations based on the decomposition of sparse Hamiltonians

description: Solving a Poisson equation is generally reduced to solving a linear system with a coefficient matrix $A$ of entries $a_{ij}$, $i,j=1,2,...,n$, from the discretized Poisson equation. Although the variational quantum algorithms are promising algorithms to solve the discretized Poisson equation, they generally require that $A$ be decomposed into a sum of $O[\text{poly}(\text{log}_2n)]$ simple operators in order to evaluate efficiently the loss function. A tensor product decomposition of $A$ with $2\text{log}_2n+1$ terms has been explored in previous works. In this paper, based on the decomposition of sparse Hamiltonians we greatly reduce the number of terms. We first write the loss function in terms of the operator $σ_x\otimes A$ with $σ_x$ denoting the standard Pauli operator. Then for the one-dimensional Poisson equations with different boundary conditions and for the $d$-dimensional Poisson equations with Dirichlet boundary conditions, we decompose $σ_x\otimes A$ into a sum of at most 7 and $(4d+1)$ Hermitian, one-sparse, and self-inverse operators, respectively. We design explicitly the quantum circuits to evaluate efficiently the loss function. The decomposition method and the design of quantum circuits can also be easily extended to linear systems with Hermitian and sparse coefficient matrices satisfying $a_{i,i+c}=a_{c}$ for $c=0,1,\cdots,n-1$ and $i=0,\cdots,n-1-c$.

description: The physics and demographics of type 2 quasars remain poorly understood, and new samples of such objects selected in a variety of ways can give insight into their physical properties, evolution, and relationship to their host galaxies. We present a sample of 2758 type 2 quasars at z $\leq$ 1 from the SDSS-III/BOSS spectroscopic database, selected on the basis of their emission-line properties. We probe the luminous end of the population by requiring the rest-frame equivalent width of [OIII] to be > 100 Å. We distinguish our objects from star-forming galaxies and type 1 quasars using line widths, standard emission line ratio diagnostic diagrams at z < 0.52 and detection of [Ne V]λ3426Å at z > 0.52. The majority of our objects have [OIII] luminosities in the range 10^8.5-10^10 L$_{\odot}$ and redshifts between 0.4 and 0.65. Our sample includes over 400 type 2 quasars with incorrectly measured redshifts in the BOSS database; such objects often show kinematic substructure or outflows in the [OIII] line. The majority of the sample has counterparts in the WISE survey, with median infrared luminosity νLν[12μm] = 4.2 x 10^44 erg/sec. Only 34 per cent of the newly identified type 2 quasars would be selected by infrared color cuts designed to identify obscured active nuclei, highlighting the difficulty of identifying complete samples of type 2 quasars. We make public the multi-Gaussian decompositions of all [OIII] profiles for the new sample and for 568 type 2 quasars from SDSS I/II, together with non-parametric measures of line profile shapes and identify over 600 candidate double-peaked [OIII] profiles.

description: Only in the Milky Way is it possible to conduct an experiment which uses stellar streams to detect low-mass dark matter subhaloes. In smooth and static host potentials, tidal tails of disrupting satellites appear highly symmetric. However, perturbations from dark subhaloes, as well as from GMCs and the Milky Way bar, can induce density fluctuations that destroy this symmetry. Motivated by the recent release of unprecedentedly deep and wide imaging data around the Pal~5 stellar stream, we develop a new probabilistic, adaptive and non-parametric technique which allows us to bring the cluster's tidal tails into clear focus. Strikingly, we uncover a stream whose density exhibits visible changes on a variety of angular scales. We detect significant bumps and dips, both narrow and broad: two peaks on either side of the progenitor, each only a fraction of a degree across, and two gaps, $\sim2^{\circ}$ and $\sim9^{\circ}$ wide, the latter accompanied by a gargantuan lump of debris. This largest density feature results in a pronounced inter-tail asymmetry which cannot be made consistent with an unperturbed stream according to a suite of simulations we have produced. We conjecture that the sharp peaks around Pal 5 are epicyclic overdensities, while the two dips are consistent with impacts by subhaloes. Assuming an age of 3.4 Gyr for Pal 5, these two gaps would correspond to the characteristic size of gaps created by subhaloes in the mass range of $10^6-10^7 M_\odot$ and $10^7-10^8 M_\odot$ respectively. In addition to dark substructure, we find that the bar of the Milky Way can plausibly produce the asymmetric density seen in Pal 5 and that GMCs could cause the smaller gap.

description: The spatial and velocity distributions of nuclear species synthesized in the innermost regions of core-collapse supernovae can yield important clues about explosion asymmetries and the operation of the still disputed explosion mechanism. Recent observations of radioactive $^{44}$Ti with high-energy satellite telescopes (Nuclear Spectroscopic Telescope Array [NuSTAR], INTEGRAL) have measured gamma-ray line details, which provide direct evidence of large-scale explosion asymmetries in SN 1987A and in Cassiopeia A (Cas A) even by mapping of the spatial brightness distribution (NuSTAR). Here we discuss a 3D simulation of a neutrino-driven explosion, using a parameterized neutrino engine, whose $^{44}$Ti distribution is mostly concentrated in one hemisphere pointing opposite to the neutron star (NS) kick velocity. Both exhibit intriguing resemblance to the observed morphology of the Cas A remnant, although neither the progenitor nor the explosion was fine-tuned for a perfect match. Our results demonstrate that the asymmetries observed in this remnant can, in principle, be accounted for by a neutrino-driven explosion, and that the high $^{44}$Ti abundance in Cas A may be explained without invoking rapid rotation or a jet-driven explosion, because neutrino-driven explosions generically eject large amounts of high-entropy matter. The recoil acceleration of the NS is connected to mass ejection asymmetries and is opposite to the direction of the stronger explosion, fully compatible with the gravitational tugboat mechanism. Our results also imply that Cas A and SN 1987A could possess similarly "one-sided" Ti and Fe asymmetries, with the difference that Cas A is viewed from a direction with large inclination angle to the NS motion, whereas the NS in SN 1987A should have a dominant velocity component pointing toward us.

description: We investigate the newly observed $X(4500)$ and $X(4700)$ based on the diquark-antidiquark configuration within the framework of QCD sum rules. Both of them may be interpreted as the $D$-wave $cs\bar{c}\bar{s}$ tetraquark states of $J^P = 0^+$, but with opposite color structures, which is remarkably similar to the result obtained in Ref.~\cite{Chen:2010ze} that the $X(4140)$ and $X(4274)$ can be both interpreted as the $S$-wave $cs\bar{c}\bar{s}$ tetraquark states of $J^P = 1^+$, also with opposite color structures. However, the extracted masses and these suggested assignments to these $X$ states do depend on these running quark masses where $m_s (2 \mbox{ GeV}) = 95 \pm 5$ MeV and $m_c (m_c) = 1.23 \pm 0.09$ GeV. As a byproduct, the masses of the hidden-bottom partner states of the $X(4500)$ and $X(4700)$ are extracted to be both around 10.64 GeV, which can be searched for in the $Υϕ$ invariant mass distribution.

description: Magnets are used in electronics to store and read information. A magnetic moment is rotated to a desired direction, so that information can later be retrieved by reading this orientation. Controlling the moment via electric currents causes resistive losses and heating, a major bottleneck in advancing computing technologies. Superconducting spintronics can resolve this using the unique features of superconductors.

description: Let $S_{E}$ be the shift operator on vector-valued Hardy space $H_{E}^{2}.$ Beurling-Lax-Halmos Theorem identifies the invariant subspaces of $S_{E}$ and hence also the invariant subspaces of the backward shift $S_{E}^{\ast}.$ In this paper, we study the invariant subspaces of $S_{E}\oplus S_{F}^{\ast}.$ We establish a one-to-one correspondence between the invariant subspaces of $S_{E}\oplus S_{F}^{\ast}$ and a class of invariant subspaces of bilateral shift $B_{E}\oplus B_{F}$ which were described by Helson and Lowdenslager. As applications, we express invariant subspaces of $S_{E}\oplus S_{F}^{\ast}$ as kernels or ranges of mixed Toeplitz operators and Hankel operators with partial isometry-valued symbols. Our approach greatly extends and gives different proofs of the results of Câmara and Ross, and Timotin where the case with one dimensional $E$ and $F$ was considered.

description: Crowd simulation is important for video-games design, since it enables to populate virtual worlds with autonomous avatars that navigate in a human-like manner. Reinforcement learning has shown great potential in simulating virtual crowds, but the design of the reward function is critical to achieving effective and efficient results. In this work, we explore the design of reward functions for reinforcement learning-based crowd simulation. We provide theoretical insights on the validity of certain reward functions according to their analytical properties, and evaluate them empirically using a range of scenarios, using the energy efficiency as the metric. Our experiments show that directly minimizing the energy usage is a viable strategy as long as it is paired with an appropriately scaled guiding potential, and enable us to study the impact of the different reward components on the behavior of the simulated crowd. Our findings can inform the development of new crowd simulation techniques, and contribute to the wider study of human-like navigation.

Polarons and Molecules in a Fermi Gas with Orbital Feshbach Resonance

description: We study the impurity problem in a gas of $^{173}$Yb atoms near the recently discovered orbital Feshbach resonance. In an orbital Feshbach resonance, atoms in the electronic ground state $^1S_0$ interact with those in the long-lived excited $^3P_0$ state with magnetically tunable interactions. We consider an impurity atom with a given hyperfine spin in the $^3P_0$ state interacting with a single-component Fermi sea of atoms in the ground $^1S_0$ manifold. Close to the orbital Feshbach resonance, the impurity can induce collective particle-hole excitations out of the Fermi sea, which can be regarded as the polaron state. While as tuning toward the BEC regime of the resonance, a molecular state becomes the ground state of the system. We show that a polaron to molecule transition exists in $^{173}$Yb atoms close to the orbital Feshbach resonance. Furthermore, due to the spin-exchange nature of the orbital Feshbach resonance, the formation of both the polaron and the molecule involve spin-flipping processes with interesting density distributions among the relevant hyperfine spin states. We show that the polaron to molecule transition can be detected using Raman spectroscopy.

description: We derive the reciprocal cluster mean-field method to study the strongly-interacting bosonic Harper-Hofstadter-Mott model. The system exhibits a rich phase diagram featuring band insulating, striped superfluid, and supersolid phases. Furthermore, for finite hopping anisotropy we observe gapless uncondensed liquid phases at integer fillings, which are analyzed by exact diagonalization. The liquid phases at fillings 1 and 3 exhibit the same band fillings as the fermionic integer quantum Hall effect, while the phase at filling 2 is CT-symmetric with zero charge response. We discuss how these phases become gapped on a quasi-one-dimensional cylinder, leading to a quantized Hall response, which we characterize by introducing a suitable measure for non-trivial many-body topological properties. Incompressible metastable states at fractional filling are also observed, indicating competing fractional quantum Hall phases. The combination of reciprocal cluster mean-field and exact diagonalization yields a promising method to analyze the properties of bosonic lattice systems with non-trivial unit cells in the thermodynamic limit.

description: Der Artikel analysiert die öffentlichen Debatten während der Pandemie und konzentriert sich dabei auf drei Facetten der Gesundheitskrise:(i) die Kriegsmetaphorik und die Heroisierungsrituale, die in den ersten Monaten der Pandemie von der Exekutive eingesetzt wurden, (ii) diePolarisierung um die umstrittene Figur des Didier Raoult und sein Therapieprotokoll gegen das Virus, und (iii) die Geographien des Protestes,die sich im Widerstand gegen die Impfkampagne und die Einführung des Gesundheitspasses formierten. Wenngleich die öffentlichen Reak-tionen auf die Pandemie sich in den meisten europäischen Ländern ähnelten, weist Frankreich bestimmte Besonderheiten auf. Diese findensich unter anderem in der starken zentralistischen Lenkung der Pandemiebekämpfung, im Einsatz von ad-hoc-Expertenkommissionen oderin der Morphologie des Protestes. Der Aufsatz zeigt, wie die Handhabung der Pandemie in vielerlei Hinsicht die kulturellen und politischenSpezifitäten Frankreichs widerspiegelt.

description: This paper utilizes Cauchy's transform and duality for the Dirichlet-type space $D(μ)$ with positive superharmonic weight $U_μ$ on the unit disk $\mathbb{D}$ to establish the corona theorem for the Dirichlet-type multiplier algebra $M\big(D(μ)\big)$ that: if $$\{f_1,...,f_n\}\subseteq M\big(D(μ)\big)\quad\text{and}\quad \inf_{z\in\mathbb{D}}\sum_{j=1}^n|f_j(z)|>0$$ then $$ \exists\,\{g_1,...,g_n\}\subseteq M\big(D(μ)\big)\quad\text{such that}\quad \sum_{j=1}^nf_jg_j=1, $$ thereby generalizing Carleson's corona theorem for $M(H^2)=H^\infty$ and Xiao's corona theorem for $M(\mathscr{D})\subset H^\infty$ thanks to $$ D(μ)=\begin{cases} \text{Hardy space}\ H^2\quad &\text{as}\quad dμ(z)=(1-|z|^2)\,dA(z)\ \ \forall\ z\in\mathbb{D};\\ \text{Dirichlet space}\ \mathscr{D}\ &\text{as}\quad dμ(z)=|dz|\ \ \forall\ z\in\mathbb{T}=\partial{\mathbb{D}}. \end{cases} $$
