description: Haïti est un pays francophone des caraïbes avec qui le Québec entretient des liens privilégiés, compte tenue d’une langue commune, d’une diaspora établie au Québec et des besoins énormes du pays. Cet état des lieux en pratique pharmaceutique à Haïti présente la mise en contexte d’un pharmacien québécois dans le cadre d’un séjour d’une semaine à Jacmel pour une mission de reconnaissance. Cet état des lieux n’a aucune prétention d’exhaustivité ni même d’exactitude absolue; connaître un pays, comprendre un système de santé et ses enjeux, apprivoiser une culture, ne s’écrivent et encore moins ne se résument en un si court séjour. Il s’agit toutefois de la meilleure intégration des données recueillies sur place en une semaine, d’abord et avant tout par la documentation retracée en ligne ou lors de discussions et d’échanges avec des acteurs du système de santé. Cet article est une annexe du rapport de mission rédigé dans le cadre du Programme de santé intégré Haïtien auquel j’ai le privilège de contribuer.

description: Positivity bounds are powerful tools to constrain effective field theories. Utilizing the partial wave expansion in the dispersion relation and the full crossing symmetry of the scattering amplitude, we derive several sets of generically nonlinear positivity bounds for a generic scalar effective field theory: We refer to these as the $PQ$, $D^{\rm su}$, $D^{\rm stu}$ and $\bar{D}^{\rm stu}$ bounds. While the $PQ$ bounds and $D^{\rm su}$ bounds only make use of the $s\leftrightarrow u$ dispersion relation, the $D^{\rm stu}$ and $\bar{D}^{\rm stu}$ bounds are obtained by further imposing the $s\leftrightarrow t$ crossing symmetry. In contradistinction to the linear positivity for scalars, these inequalities can be applied to put upper and lower bounds on Wilson coefficients, and are much more constraining as shown in the lowest orders. In particular we are able to exclude theories with soft amplitude behaviour such as weakly broken Galileon theories from admitting a standard UV completion. We also apply these bounds to chiral perturbation theory and we find these bounds are stronger than the previous bounds in constraining its Wilson coefficients.

description: Auch heute, knapp drei Jahrzehnte nach dem Zusammenbruch der DDR und dem Beitritt des kleineren ostdeutschen Staates zur größeren Bundesrepublik hat sich die Zeitgeschichte noch kaum mit der Frage auseinandergesetzt, wie sich das, was seit 1990 auf dem Boden des nunmehr voll-souveränen Deutschlands entstand, in geschichtswissenschaftlicher Perspektive erfassen, verstehen und einordnen lässt. Für die These, dass es sich bei der nach Osten erweiterten Bundesrepublik nicht bloß um eine Fortsetzung von Altbekanntem, sondern teilweise um etwas Neues handelte, sprachen neben dem radikal gewandelten internationalen Kontext schon aus zeitgenössischer Sicht die besonderen Bedingungen des politischen Umbruchs in der spätsozialistischen DDR. Verglichen mit den kommunistischen Nachbarstaaten waren die Umwälzungen in Ostdeutschland durch ein besonders hohes Tempo geprägt. Binnen weniger Monate kollabierte ein politisches, wirtschaftliches und gesellschaftliches System, welches sich bis dahin – trotz vielfältiger Anpassungsschwierigkeiten und Krisenerscheinungen – durch einen bemerkenswerten Grad an Stabilität und Selbstbewusstsein ausgezeichnet hatte. Neben dem schlagartigen Zerfall des SED-Staats stellte die schnelle Übertragung des politischen und sozioökonomischen Modells der Bundesrepublik die zweite große Besonderheit dar. In der sozialwissenschaftlichen Literatur wird dieser Vorgang wahlweise als eine „von therapeutischen Maßnahmen bereinigte Schocktherapie“, als „natürliches Experiment“ oder als „electric chair therapy“ bezeichnet: Mit dem erklärten Ziel, innerhalb kürzester Zeit eine vollständige Angleichung an westdeutsche Produktivitäts-, Lohn-, Konsum- und Rechtsstandards zu erreichen, wurden sämtliche institutionellen Arrangements der alten Bundesrepublik in die neuen Bundesländer transplantiert. Die Geschwindigkeit, Totalität und Radikalität, in der sich diese Veränderungsprozesse vollzogen, setzten wiederum verschiedene Dynamiken in Gang, für die Jürgen Kocka seinerzeit den Begriff der „Vereinigungskrise“ geprägt hat.

description: We consider C1 Anosov diffeomorphisms on a compact Riemannian manifold. We define the weak pseudo-physical measures, which include the physical measures when these latter exist. We prove that ergodic weak pseudo-physical measures do exist, and that the set of invariant probability measures that satisfy Pesin's Entropy Formula is the weak*-closed convex hull of the ergodic weak pseudo-physical measures. In brief, we give in the C1-scenario of uniform hyperbolicity, a characterization of Pesin's Entropy Formula in terms of physical-like properties.
Two-Point Correlator of Chiral Primary Operators with a Wilson Line Defect in $\mathcal{N}=4$ SYM

description: We study the two-point function of the stress-tensor multiplet of $\mathcal{N}=4$ SYM in the presence of a line defect. To be more precise, we focus on the single-trace operator of conformal dimension two that sits in the $20'$ irrep of the $\mathfrak{so}(6)_\text{R}$ R-symmetry, and add a Maldacena-Wilson line to the configuration which makes the two-point function non-trivial. We use a combination of perturbation theory and defect CFT techniques to obtain results up to next-to-leading order in the coupling constant. Being a defect CFT correlator, there exist two (super)conformal block expansions which capture defect and bulk data respectively. We present a closed-form formula for the defect CFT data, which allows to write an efficient Taylor series for the correlator in the limit when one of the operators is close to the line. The bulk channel is technically harder and closed-form formulae are particularly challenging to obtain, nevertheless we use our analysis to check against well-known data of $\mathcal{N}=4$ SYM. In particular, we recover the correct anomalous dimensions of a famous tower of twist-two operators (which includes the Konishi multiplet), and successfully compare the one-point function of the stress-tensor multiplet with results obtained using matrix-model techniques.

The magnetooptical Kerr effect (MOKE) and ferromagnetic resonance (FMR) measurements show up the essentially non-collinear state of magnetic moments of the layers and strong exchange coupling between CoPt and Co subsystems. The estimation of effective anisotropy and exchange coupling in a simple model based on the Landau-Lifshitz-Gilbert equation describing magnetization dynamics was performed.

description: We present Herschel PACS $\&$ SPIRE far-infrared (FIR) and sub-mm imaging observations for a large K-band selected sample of 88 close major-merger pairs of galaxies (H-KPAIRs) in 6 photometric bands (70, 100, 160, 250, 350, and 500 $μm$). Among 132 spiral galaxies in the 44 spiral-spiral (S$+$S) pairs and 44 spiral-elliptical (S$+$E) pairs, 113 are detected in at least one Herschel band. Star formation rate (SFR) and dust mass ($M_{\rm dust}$) are derived from the IR SED fitting. Mass of total gas ($M_{\rm gas}$) is estimated by assuming a constant dust-to-gas mass ratio of 0.01. Star forming spiral galaxies (SFGs) in S$+$S pairs show significant enhancements in both specific star formation rate (sSFR) and star formation efficiency (SFE), while having nearly the same gas mass, compared to control galaxies. On the other hand, for SFGs in S$+$E pairs, there is no significant sSFR enhancement and the mean SFE enhancement is significantly lower than that of SFGs in S$+$S pairs. This suggests an important role for the disc-disc collision in the interaction induced star formation. The $M_{\rm gas}$ of SFGs in S$+$E pairs is marginally lower than that of their counterparts in both S$+$S pairs and the control sample. Paired galaxies with and without interaction signs do not differ significantly in their mean sSFR and SFE. As found in previous works, this much larger sample confirms the primary and secondary spirals in S+S pairs follow a Holmberg effect correlation on sSFR.

description: Motivated by recent experiments with a Penning ion trap quantum simulator, we perform numerically exact Stochastic Series Expansion quantum Monte Carlo simulations of long-range transverse-field Ising models on a triangular lattice for different decay powers $α$ of the interactions. The phase boundary for the ferromagnet is obtained as a function of $α$. For antiferromagnetic interactions, there is strong indication that the transverse field stabilizes a clock ordered phase with sublattice magnetization $(M,-\frac{M}{2}, -\frac{M}{2})$ with unsaturated $M < 1$ in a process known as "order by disorder" similar to the nearest neighbour antiferromagnet on the triangular lattice. Connecting the known limiting cases of nearest neighbour and infinite-range interactions, a semiquantitative phase diagram is obtained. Magnetization curves for the ferromagnet for experimentally relevant system sizes and with open boundary conditions are presented.

description: A theory is developed for the initial stage of cavitation in the framework of Zel'dovich-Fisher theory of nucleation in the field of negative pressure, while taking into account the surface tension dependence on the nanopore radius. A saturation mechanism is proposed that limits the exponential dependence of the nucleation rate on the energy required to create nanopores. An estimate of the saturated density of nanopores at the nucleation stage is obtained. It is shown that Rayleigh scattering can detect nanopores arising at the initial stage of cavitation development.

description: The purpose of this paper is to study $T$-periodic solutions to [(-Δ_{x}+m^{2})^{s}-m^{2s}]u=f(x,u) &\mbox{in} (0,T)^{N} (P) u(x+Te_{i})=u(x) &\mbox{for all} x \in \R^{N}, i=1, \dots, N where $s\in (0,1)$, $N>2s$, $T>0$, $m> 0$ and $f(x,u)$ is a continuous function, $T$-periodic in $x$ and satisfying a suitable growth assumption weaker than the Ambrosetti-Rabinowitz condition. The nonlocal operator $(-Δ_{x}+m^{2})^{s}$ can be realized as the Dirichlet to Neumann map for a degenerate elliptic problem posed on the half-cylinder $\mathcal{S}_{T}=(0,T)^{N}\times (0,\infty)$. By using a variant of the Linking Theorem, we show that the extended problem in $\mathcal{S}_{T}$ admits a nontrivial solution $v(x,ξ)$ which is $T$-periodic in $x$. Moreover, by a procedure of limit as $m\rightarrow 0$, we also prove the existence of a nontrivial solution to (P) with $m=0$.

description: Characterizing many-body systems through the quantum correlations between their constituent particles is a major goal of quantum physics. Although entanglement is routinely observed in many systems, we report here the detection of stronger correlations - Bell correlations - between the spins of about 480 atoms in a Bose-Einstein condensate. We derive a Bell correlation witness from a many-particle Bell inequality involving only one- and two-body correlation functions. Our measurement on a spin-squeezed state exceeds the threshold for Bell correlations by 3.8 standard deviations. Our work shows that the strongest possible non-classical correlations are experimentally accessible in many-body systems, and that they can be revealed by collective measurements.

description: Als vor gut zehn Jahren meine Studie über „Das Schicksal der DDR-Verlage“ im Prozess der deutschen Vereinigung erschien, gab es große mediale Aufregung über die Resultate. Die Zahlen waren tatsächlich erschütternd: Von den ehemals 78 staatlich lizenzierten Verlagen der DDR existierte 2006 in eigenständiger Form nur noch ein Dutzend, was etwa 15% entsprach. Nach Wirtschaftskraft betrachtet, waren die ostdeutschen Verlage inzwischen fast vollständig zu vernachlässigen: Am Gesamtumsatz der deutschen Buchbranche von damals 10,7 Mrd. € waren Firmen aus den neuen Bundesländern (ohne Berlin) 2006 nur noch mit 0,9 % beteiligt. Das Erschrecken war nicht nur deshalb so groß, weil selbst die meisten Branchenteilnehmer einen gefühlt anderen Eindruck hatten, sondern weil die Verlagsbranche damit noch unter dem Ergebnis anderer Wirtschaftsbereiche Ostdeutschlands lag, denn nach Treuhandangaben sind dort insgesamt rund 20% der Betriebe erhalten geblieben. Schaut man sich die Situation heute an, hat sich die Lage keineswegs verbessert. Zwar haben einige Verlage ihren Sitz nach Berlin verlagert und sind ein paar neugegründete Kleinstverlage hinzugekommen, doch die Gesamtlage hat sich kaum verbessert. An der Gesamttitelproduktion sind die ostdeutschen Bundesländer (ohne Berlin) nach wie vor nur mit insgesamt 5% beteiligt.

The influence of the Extreme Ultraviolet spectral energy distribution on the structure and composition of the upper atmosphere of exoplanets

description: By varying the profiles of stellar extreme ultraviolet (EUV) spectral energy distribution (SED), we tested the influences of stellar EUV SEDs on the physical and chemical properties of the escaping atmosphere. We apply our model to study four exoplanets, HD\,189733b, HD\,209458b, GJ \,436b, and Kepler-11b. We found that the total mass loss rates of an exoplanet, which are determined mainly by the integrated fluxes, are moderately affected by the profiles of the EUV SED, but the composition and species distributions in the atmosphere can be dramatically modified by the different profiles of the EUV SED. For exoplanets with a high hydrodynamic escape parameter ($λ$), the amount of atomic hydrogen produced by photoionization at different altitudes can vary by one to two orders of magnitude with the variation of stellar EUV SEDs. The effect of photoionization of H is prominent when the EUV SED is dominated by the low-energy spectral region (400-900$Å$), which pushes the transition of H/H$^{+}$ to low altitudes. On the contrary, the transitions of H/H$^{+}$ move to higher altitudes when most photons concentrate in the high-energy spectral region (50-400$Å$). For exoplanets with a low $λ$, the lower temperatures of the atmosphere make many chemical reactions so important that photoionization alone can no longer determine the composition of the escaping atmosphere. For HD 189733b, it is possible to explain the time variability of \lya\ between 2010 and 2011 by a change in the EUV SED of the host K star, yet invoking only thermal H\,I in the atmosphere.

description: We study finite $N$ aspects of the $O(m)\times O(N-m)$ vector model with quartic interactions in general $2\leq d \leq 6$ spacetime dimensions. This model has recently been shown to display the phenomenon of persistent symmetry breaking at a perturbative Wilson-Fisher-like fixed point in $d=4-ε$ dimensions. The large rank limit of the bi-conical model displays a conformal manifold and a moduli space of vacua. We find a set of three double trace scalar operators that are respectively irrelevant, relevant and marginal deformations of the conformal manifold in general $d$. We calculate the anomalous dimensions of the single and multi-trace scalar operators to the first sub-leading order in the large rank expansion. The anomalous dimension of the marginal operator does not vanish in general, indicating that the conformal manifold is lifted at finite $N$. In the case of equal ranks we are able to derive explicitly the scaling dimensions of various operators as functions of only $d$.

description: We classify the necessary and sufficient conditions to obtain the near-horizon geometry of extremal supersymmetric rotating black holes embedded in 11d supergravity. Such rotating black holes admit an AdS$_2$ near-horizon geometry which is fibered by the transverse spacetime directions. Despite their clear interest to understanding the entropy of rotating black holes, these solutions have evaded all previous supersymmetric classification programs due to the non-trivial fibration structure. In this paper we allow for the most general fibration over AdS$_2$ with a flux configuration permitting rotating M2-branes. Using G-structure techniques we rewrite the conditions for supersymmetry in terms of differential equations on an eight-dimensional balanced space. The 9d compact internal space is a U$(1)$-fibration over this 8d base. The geometry is constrained by a master equation reminiscent of the one found in the non-rotating case. We give a Lagrangian from which the equations of motion may be derived, and show how the asymptotically AdS$_4$ electrically charged Kerr-Newman black hole in 4d $\mathcal{N}=2$ supergravity is embedded in the classification. In addition, we present the conditions for the near-horizon geometry of rotating black strings in Type IIB by using dualities with the 11d setup.

description: In this paper we take further steps towards developing the separation of variables program for integrable spin chains with gl(N) symmetry. By finding, for the first time, the matrix elements of the SoV measure explicitly we were able to compute correlation functions and wave function overlaps in a simple determinant form. In particular, we show how an overlap between on-shell and off-shell algebraic Bethe states can be written as a determinant. Another result, particularly useful for AdS/CFT applications, is an overlap between two Bethe states with different twists, which also takes a determinant form in our approach. Our results also extend our previous works in collaboration with A. Cavaglia and D. Volin to general values of the spin, including the SoV construction in the higher-rank non-compact case for the first time.

description: Dark matter in spiral galaxies like the Milky Way may take the form of a dark plasma. Hidden sector dark matter charged under an unbroken $U(1)'$ gauge interaction provides a simple and well defined particle physics model realising this possibility. The assumed $U(1)'$ neutrality of the Universe then implies (at least) two oppositely charged dark matter components with self-interactions mediated via a massless "dark photon" (the $U(1)'$ gauge boson). In addition to nuclear recoils such dark matter can give rise to keV electron recoils in direct detection experiments. In this context, the detailed physical properties of the dark matter plasma interacting with the Earth is required. This is a complex system, which is here modelled as a fluid governed by the magnetohydrodynamic equations. These equations are numerically solved for some illustrative examples, and implications for direct detection experiments discussed. In particular, the analysis presented here leaves open the intriguing possibility that the DAMA annual modulation signal is due primarily to electron recoils (or even a combination of electron recoils and nuclear recoils). The importance of diurnal modulation (in addition to annual modulation) as a means of probing this kind of dark matter is also emphasised.

description: In der DDR entwickelte sich eine staatssozialistische „Geltungskunst“, die man als „DDR-Kunst“ oder „Kunst der DDR“ bezeichnen könnte im Unterschied zu den vielfältigeren Formen einer „Kunst in der DDR“. Diese mit dem politischen Projekt eng verbundene Kunst sollte von allen historischen wie zeitgenössischen Moderne-Anhaftungen bereinigt werden, was in der Komplexität künstlerischer Produktions- und Rezeptionsweisen allerdings nur ansatzweise gelang. Auch wenn der Wirkungsgrad jener an einer didaktischen Symbolisierung der sozialistischen Leitideen beteiligten Künste die Erwartungen der Machthaber nur unzureichend erfüllte, so blieb die Kunst des „Sozialistischen Realismus“ doch innen- wie außenpolitisch ein unverzichtbares Instrument der Herrschaftslegitimation. Die SED-Funktionäre versuchten, den „Sozialistischen Realismus“ als Widerpart zum westlichen Modell einer kosmopolitischen „Weltkunst“ in Stellung zu bringen. Somit wurde für die offizialkulturelle Kunstproduktion der DDR anstatt des intrinsischen Moderne-Konfliktes zwischen Autonomie und institutionalisierter Kunst von Anbeginn eine andere Gegensatzspannung prägend – die zwischen Ost und West.

description: Using the ambitwistor string, we compute tree-level celestial amplitudes for biadjoint scalars, Yang-Mills and gravity to all multiplicities. They are presented in compact CHY-like formulas with operator-valued scattering equations and numerators acting on a generalized hypergeometric function. With these we extend the celestial double copy to tree-level amplitudes with arbitrary number of external states. We also show how color-kinematics duality is implemented in celestial amplitudes and its interpretation in terms of a generalized twisted cohomology theory.

description: We analyze the free energy of the integrable two dimensional O(4) sigma model in a magnetic field. We use Volin's method to extract high number (2000) of perturbative coefficients with very high precision. The factorial growth of these coefficients are regulated by switching to the Borel transform, where we perform several asymptotic analysis. High precision data allowed to identify Stokes constants and alien derivatives with exact expressions. These reveal a nice resurgence structure which enables to formulate the first few terms of the ambiguity free trans-series. We check these results against the direct numerical solution of the exact integral equation and find complete agreement.

description: Im Jahr 1993 oder 1994 zeigte mir mein Vater ein wackeliges Video. Er und seine ehemaligen Arbeitskollegen hatten gemeinsam ein Schwein aufgezogen, und nun sollte jeder seinen Anteil bekommen. Im Video sah man, wie die Sau über den Hof getrieben wird, dann bindet sie jemand am Hinterlauf fest. Das Tier wird „Wessi“ getauft. Die Männer johlen, das Bier fließt. Dann wird Wessi mit einem Bolzenschussgerät niedergestreckt, das Schwein zappelt am Boden, jemand sticht in die Halsschlagader, das Blut strömt in einen bereitgestellten Bottich. Mein Vater wirft sich auf die Sau, um sie zu fixieren. Es ist der 7. Oktober, das Datum des ehemaligen „Tags der Republik“ der DDR. Das Schwein wird mit kochendem Wasser übergossen und abgeschabt. Wessi wird zu Wurst verarbeitet.

description: A framework is presented to extract and understand decision-making information from a deep neural network (DNN) classifier of jet substructure tagging techniques. The general method studied is to provide expert variables that augment inputs ("eXpert AUGmented" variables, or XAUG variables), then apply layerwise relevance propagation (LRP) to networks both with and without XAUG variables. The XAUG variables are concatenated with the intermediate layers after network-specific operations (such as convolution or recurrence), and used in the final layers of the network. The results of comparing networks with and without the addition of XAUG variables show that XAUG variables can be used to interpret classifier behavior, increase discrimination ability when combined with low-level features, and in some cases capture the behavior of the classifier completely. The LRP technique can be used to find relevant information the network is using, and when combined with the XAUG variables, can be used to rank features, allowing one to find a reduced set of features that capture part of the network performance. In the studies presented, adding XAUG variables to low-level DNNs increased the efficiency of classifiers by as much as 30-40\%. In addition to performance improvements, an approach to quantify numerical uncertainties in the training of these DNNs is presented.

description: It has been widely debated whether Arctic sea-ice loss can reach a tipping point beyond which a large sea-ice area disappears abruptly. The theory of dynamical systems predicts a slowing down when a system destabilises towards a tipping point. In simple stochastic systems this can result in increasing variance and autocorrelation, potentially yielding an early warning of an abrupt change. Here we aim to establish whether the loss of Arctic sea ice would follow these conceptual predictions, and which trends in sea ice variability can be expected from pre-industrial conditions toward an Arctic that is ice-free during the whole year. To this end, we apply a model hierarchy consisting of two box models and one comprehensive Earth system model. We find a consistent and robust decrease of the ice volume's annual relaxation time before summer ice is lost because thinner ice can adjust more quickly to perturbations. Thereafter, the relaxation time increases, mainly because the system becomes dominated by the ocean water's large heat capacity when the ice-free season becomes longer. Both trends carry over to the autocorrelation of sea ice thickness in time series. These changes are robust to the nature and origin of climate variability in the models and hardly depend on the balance of feedbacks. Therefore, characteristic trends can be expected in the future. As these trends are not specific to the existence of abrupt ice loss, the prospects for early warnings seem very limited. This result also has implications for statistical indicators in other systems whose effective mass changes over time, affecting the trend of their relaxation time. However, the robust relation between state and variability would allow an estimate of sea-ice variability from only short observations. This could help one to estimate the likelihood and persistence of extreme events in the future.

Non-relativistic and Carrollian limits of Jackiw-Teitelboim gravity

description: We construct the non-relativistic and Carrollian versions of Jackiw-Teitelboim gravity. In the second order formulation, there are no divergences in the non-relativistic and Carrollian limits. Instead, in the first order formalism there are divergences that can be avoided by starting from a relativistic BF theory with (A)dS2$\times\mathbb{R}$ gauge algebra. We show how to define the boundary duals of the gravity actions using the method of non-linear realisations and suitable Inverse Higgs constraints. In particular, the non-relativistic version of the Schwarzian action is constructed in this way. We derive the asymptotic symmetries of the theory, as well as the corresponding conserved charges and Newton-Cartan geometric structure. Finally, we show how the same construction applies to the Carrollian case.

Reduced Wiener Chaos representation of random fields via basis adaptation and projection

Year: 2016

description: A new characterization of random fields appearing in physical models is presented that is based on their well-known Homogeneous Chaos expansions. We take advantage of the adaptation capabilities of these expansions where the core idea is to rotate the basis of the underlying Gaussian Hilbert space, in order to achieve reduced functional representations that concentrate the induced probability measure in a lower dimensional subspace. For a smooth family of rotations along the domain of interest, the uncorrelated Gaussian inputs are transformed into a Gaussian process, thus introducing a mesoscale that captures intermediate characteristics of the quantity of interest.

Analytic and Numerical Models of Oxygen and Nutrient Diffusion, Metabolism Dynamics, and Architecture Optimization in Three-Dimensional Tissue Constructs with Applications and Insights in Cerebral Organoids

description: Diffusion models are important in tissue engineering as they enable an understanding of molecular delivery to cells in tissue constructs. As three-dimensional (3D) tissue constructs become larger, more intricate, and more clinically applicable, it will be essential to understand internal dynamics and signaling molecule concentrations throughout the tissue. Diffusion characteristics present a significant limitation in many engineered tissues, particularly for avascular tissues and for cells whose viability, differentiation, or function are affected by concentrations of oxygen and nutrients. This paper seeks to provide novel analytic solutions for certain cases of steady-state and non-steady-state diffusion and metabolism in 3D construct designs (planar, cylindrical, and spherical forms), solutions that otherwise require mathematical approximations achieved through numerical methods. This model is applied to cerebral organoids, where it is shown that limitations in diffusion and organoid size can be partially overcome by localizing metabolically-active cells to an outer layer in a sphere, a regionalization process that is known to occur through neuroglial precursor migration both in organoids and in early brain development. The given prototypical solutions include a review of metabolic information for many cell types and can be broadly applied to many forms of tissue constructs. This work enables researchers to model oxygen and nutrient delivery to cells, predict cell viability, design constructs with improved diffusion capabilities, and accurately control molecular concentrations in tissue constructs that may be used in studying models of development and disease or for conditioning cells to enhance survival after insults like ischemia or implantation into the body, thereby providing a framework for better understanding and exploring the characteristics of engineered tissue constructs.
