Year: 2016
Subjects: Uncategorized

description: This paper explains an approach for appraising the extent and quality of native vegetation and identifying significant habitats at strategic regional and local levels. The Vegetation and Habitat Conservation Significance Framework (hereafter the framework) is formulated through a planning process which includes seven stages from defining the Purpose of the study (Stage 1) to Implementation and monitoring (Stage 7). The cornerstone of the framework is the formulation, in Stage 3, of a Regional Habitat Significance Model which integrates the Analytic Hierarchy Process (AHP) with Geographic Information System (GIS). An expert workshop (Stage 4) is an integral part of model construction and should comprise 10 to 15 persons including environmental and land use scientists, ecologists, planners and landscape architects with good knowledge of vegetation, biodiversity and habitat matters, as well as relevant decision-makers. Experts are provided with all the data sets generated in Stage 2, and limitations and advantages of each data set are discussed. The initial construction of the model (undertaken at Stage 3) is validated, or modified, and then its components are weighted through consensus of the experts. The GIS platform permits the ongoing improvement and input of the latest, relevant information and the preparation of a new assessment in a cyclical planning process. The method is predominantly explained by reference to its application in the rural shire of Macedon Ranges, State of Victoria, Australia.

description: We study the mass spectra and decay process of $σ$ and $π_0$ mesons under strong external magnetic field. For this purpose, we deduce the thermodynamic potential in a two-flavor, hot and magnetized Nambu-Jona-Lasinio model. We calculate the energy gap equation through the random phase approximation(RPA). Then we use Ritus method to calculate the decay triangle diagram and self-energy in the presence of a constant magnetic field B. Our results indicate that the magnetic field has little influence on the mass of $π_0$ at low temperatures. While for quarks and $σ$ mesons, their mass changes obviously, which reflects the influence of magnetic catalysis(MC). The presence of magnetic field accelerates the decay of the meson while the presence of chemical potential will decrease the decay process.

description: This study describes a method used to improve ore grade estimation in a limestone deposit in India. Ore grade estimation for the limestone deposit was complicated by the complex lithological structure of the deposit. The erratic nature of the deposit and the unavailability of adequate samples for each of the lithogical units made standard geostatistical methods of capturing the spatial variation of the deposit inadequate. This paper describes an attempt to improve the ore grade estimation through the use of a feed forward neural network (NN) model. The NN model incorporated the spatial location as well as the lithological information for modeling of the ore body. The network was made up of three layers: an input, an output and a hidden layer. The input layer consisted of three spatial coordinates (x, y and z) and nine lithotypes. The output layer comprised all the grade attributes of limestone ore including silica (SiO2), alumina (Al2O3), calcium oxide (CaO) and ferrous oxide (Fe2O3). To justify the use of the NN in the deposit, a comparative evaluation between the NN method and the ordinary kriging was performed. This evaluation demonstrated that the NN model decisively outperformed the kriging model. After the superiority of the NN model had been established, it was used to predict the grades at an unknown grid location. Prior to constructing the grade maps, lithological maps of the deposit at the unknown grid were prepared. These lithological maps were generated using indicator kriging. The authors conclude by suggesting that the method described in this paper could be used for grade-control planning in ore deposits.

description: Background: Several studies suggest high distress in parents of a child with Down syndrome. This study focused on the relationship between stress, individual, dyadic and social resources and different measures of well-being based on a theoretical stress model. Method: Path analyses separated for parental sex and functionality of coping were used to test the theoretical model using data collected from 75 couples. Results: Data supported the model with maternal emotional and paternal as well as maternal instrumental resources in the context of specific child related stress. Conclusion: The results underline the importance of the marital system for dealing with daily stress, but they also reveal that individual and social resources are needed. Zusammenfassung Theoretischer Hintergrund: Bestehende Befunde verweisen auf ein erhöhtes Belastungsniveau bei Eltern von einem Kind mit einem Down-Syndrom. In der vorliegenden Untersuchung sollte nun erstmals eine differenzierte Betrachtung der Zusammenhänge zwischen elterlichen Belastungen aufgrund des Kindes mit einem Down-Syndrom, individuellen, dyadischen sowie sozialen Ressourcen und Befindlichkeitsvariablen durch die empirische Überprüfung eines theoretischen Stressmodells erfolgen. Methode: Das Stressmodell wurde sowohl für das elterliche Geschlecht als auch die Copingfunktion getrennt mittels Pfadanalysen an den Angaben von 75 Elternpaaren berechnet. Ergebnisse: Das pfadanalytische Modell konnte mit den emotionalen mütterlichen und instrumentellen Ressourcen beider Elternteile belegt werden. Schlussfolgerung: Obwohl die Wichtigkeit der partnerschaftlichen Unterstützung bei der Bewältigung von kindbezogenen Belastungen bestätigt wurde, waren individuelle und soziale Ressourcen von Bedeutung.

description: Quantum fields do not satisfy the pointwise energy conditions that are assumed in the original singularity theorems of Penrose and Hawking. Accordingly, semiclassical quantum gravity lies outside their scope. Although a number of singularity theorems have been derived under weakened energy conditions, none is directly derived from quantum field theory. Here, we employ a quantum energy inequality satisfied by the quantized minimally coupled linear scalar field to derive a singularity theorem valid in semiclassical gravity. By considering a toy cosmological model, we show that our result predicts timelike geodesic incompleteness on plausible timescales with reasonable conditions at a spacelike Cauchy surface.

description: The nonlinear evolution of electromagnetic instabilities driven by the interpenetration of two $e^-\,e^+$ plasma clouds is explored using {\it ab initio} kinetic plasma simulations. We show that the plasma clouds slow down due to both oblique and Weibel generated electromagnetic fields, which deflect the particle trajectories, transferring bulk forward momentum into transverse momentum and thermal velocity spread. This process causes the flow velocity $v_{inst}$ to decrease approximately by a factor of $\sqrt{1/3}$ in a time interval $Δt_{αB} ω_p \sim c/(v_{fl}\sqrt{α_B})$, where $α_B$ is the magnetic equipartition parameter determined by the non-linear saturation of the instabilities, $v_{fl}$ is the initial flow speed, and $ω_p$ is the plasma frequency. For the $α_B$ measured in our simulations, $Δt_{αB}$ is close to $10 \times$ the instability growth time. We show that as long as the plasma slab length $L > v_{fl} Δt_{αB}$, the plasma flow is expected to slow down by a factor close to $1/\sqrt{3}$.

description: Calculations of high-energy processes involving the production of a large number of particles in weakly-coupled quantum field theories have previously signaled the need for novel non-perturbative behavior or even new physical phenomena. In some scenarios, already tree-level computations may enter the regime of large-order perturbation theory and therefore require a careful investigation. We demonstrate that in scalar quantum field theories with a unique global minimum, where suitably resummed perturbative expansions are expected to capture all relevant physical effects, perturbation theory may still suffer from severe shortcomings in the high-energy regime. As an example, we consider the computation of multiparticle threshold amplitudes of the form $1 \to n$ in $φ^6$ theory with a positive mass term, and show that they may violate unitarity of the quantum theory for large $n$, even after the resummation of all leading-$n$ quantum corrections. We further argue that this is a generic feature of scalar field theories with higher-order self-interactions beyond $φ^4$, thereby rendering the latter unique with respect to its high-energy behavior.

description: We developed a novel contactless frequency-domain approach to study thermal transport, which is particularly convenient when thermally anisotropic materials are considered. The method is based on a similar line-shaped heater geometry as used in the 3-omega method, however, keeping all the technical advantages offered by non-contact methodologies. The present method is especially suitable to determine all the elements of the thermal conductivity tensor, which is experimentally achieved by simply rotating the sample with respect to the line-shaped optical heater. We provide the mathematical solution of the heat equation for the cases of anisotropic substrates, multilayers, as well as thin films. This methodology allows an accurate determination of the thermal conductivity, and does not require complex modeling or intensive computational efforts to process the experimental data, i.e., the thermal conductivity is obtained through a simple linear fit ("slope method"), in a similar fashion as in the 3-omega method. We demonstrate the potential of this approach by studying isotropic and anisotropic materials in a wide range of thermal conductivities. In particular, we have studied the following inorganic and organic systems: (i) glass, Si, and Ge substrates (isotropic), (ii) $β$-Ga$_2$O$_3$, and a Kapton substrate (anisotropic) and , (iii) a 285 nm SiO$_2$/Si thin film. The accuracy in the determination of the thermal conductivity is estimated at $\approx$ 5\%, whereas the best temperature resolution is $Δ$T $\approx$ 3 mK.

Nucleotide augmentation for machine learning-guided protein engineering

Publisher: name: ETH Zurich
Year: 2022

description: Machine learning-guided protein engineering is a rapidly advancing field. Despite major experimental and computational advances however, collecting protein genotype (sequence) and phenotype (function) data remains time and resource intensive. As a result, the quality and quantity of training data is often a limiting factor in developing machine learning models. Data augmentation techniques have been successfully applied to the fields of computer vision and natural language processing, however, there is a lack of such augmentation techniques for biological sequence data. Towards this end we develop nucleotide augmentation (NTA), which leverages natural nucleotide codon degeneracy to augment protein sequence data in a biologically meaningful way. As a proof of concept for protein engineering, we apply NTA to train machine learning models with benchmark data sets of protein genotype and phenotype, revealing performance gains on par and surpassing benchmarks models, even when only using a fraction of the training data. NTA also enables substantial improvements for classification tasks under heavy class imbalance.

description: We perform a full 3D general relativistic magnetohydrodynamical (GRMHD) simulation of an equal-mass, spinning, binary black hole approaching merger, surrounded by a circumbinary disk and with mini-disks around each black hole. For this purpose, we evolve the ideal GRMHD equations on top of an approximated spacetime for the binary that is valid in every position of space, including the black hole horizons, during the inspiral regime. We use relaxed initial data for the circumbinary disk from a previous long-term simulation, where the accretion is dominated by an $m=1$ overdensity called the lump. We compare our new spinning simulation with a previous non-spinning run, studying how spin influences the mini-disk properties. We analyze the accretion from the inner edge of the lump to the black hole, focusing on the angular momentum budget of the fluid around the mini-disks. We find that mini-disks in the spinning case have more mass over a cycle than the non-spinning case. However, in both cases, we find most of the mass received by the black holes is delivered by the direct plunging of material from the lump. We also analyze the morphology and variability of the electromagnetic fluxes and we find they share the same periodicities of the accretion rate. In the spinning case, we find that the outflows are $8$ times stronger than the non-spinning case. Our results will be useful to understand and produce realistic synthetic light curves and spectra, which can be used in future observations.

description: In recent years, physical informed neural networks (PINNs) have been shown to be a powerful tool for solving PDEs empirically. However, numerical analysis of PINNs is still missing. In this paper, we prove the convergence rate to PINNs for the second order elliptic equations with Dirichlet boundary condition, by establishing the upper bounds on the number of training samples, depth and width of the deep neural networks to achieve desired accuracy. The error of PINNs is decomposed into approximation error and statistical error, where the approximation error is given in $C^2$ norm with $\mathrm{ReLU}^{3}$ networks (deep network with activations function $\max\{0,x^3\}$) and the statistical error is estimated by Rademacher complexity. We derive the bound on the Rademacher complexity of the non-Lipschitz composition of gradient norm with $\mathrm{ReLU}^{3}$ network, which is of immense independent interest.

description: We develop a polarization characterization platform for optical devices in free-space quantum communications. We demonstrate an imaging polarimeter, which analyzes both incident polarization states and the angle of incidence, attached to a six-axis collaborative robot arm, enabling polarization characterization at any position and direction with consistent precision. We present a detailed description of each subsystem including the calibration and polarization-test procedure, and analyze polarization-measurement errors caused by imperfect orientations of the robot arm using a Mueller-matrix model of polarimeters at tilt incidence. We perform a proof-of-principle experiment for an angle-dependent polarization test for a commercial silver-coated mirror for which the polarization states of the reflected light can be accurately calculated. Quantitative agreement between the theory and experiment validates our methodology. We demonstrate the polarization test for a 20.3 cm lens designed for a quantum optical transmitter in Canada's Quantum Encryption and Science Satellite (QEYSSat) mission.

description: Background : Several recent experiments report significant low-energy isoscalar monopole strength, below the giant resonance, in various nuclei. In light $α$-conjugate nuclei, these low-energy resonances were recently interpreted as cluster vibration modes. However, the nature of these excitations in neutron-rich nuclei remain elusive. Purpose : The present work provides a systematic analysis of the low-energy monopole strength in isotopic chains, from Neon to Germanium, in order to monitor and understand its nature and conditions of emergence. Methods : We perform covariant quasiparticle random phase approximation (QRPA) calculations, formulated within the finite amplitude method (FAM), on top of constrained relativistic Hartree-Bogoliubov (RHB) reference states. Results : Neutron excess leads to the appearance of low-energy excitations according to a systematic pattern reflecting the single-particle features of the underlying RHB reference state. With the onset of deformation, these low-energy resonances get split and give rise to more complex patterns, with possible mixing with the giant resonance. At lower energy, cluster-like excitations found in $N=Z$ systems survive in neutron-rich nuclei, with valence neutrons arranging in molecular-like orbitals. Finally, at very low energy, pair excitations are also found in superfluid nuclei, but remain negligible in most of the cases. Conclusions : The low-energy part of the monopole strength exhibits various modes, from cluster vibrations ($\sim$ 5-10 MeV) to components of the giant resonance downshifted by the onset of deformation, including soft modes ($\sim$ 10-15 MeV) as well as pair excitation ($

GIS-based evaluation of Personal Rapid Transit (PRT) for reducing car dependence within Melbourne, Australia

Year: 2016
Subjects: Uncategorized

description: Metropolitan Melbournes car dependence continues to grow. This is despite major expenditure on trams, trains and buses as well as attempts to alter land use patterns to make suburbs easier to service by public transport. Melbournians are simply reluctant to give up the flexibility, convenience, speed and privacy advantages that cars still hold over conventional public transport modes. Accordingly, we have here resurrect a less conventional public transport mode, first mooted during the 1960s and known as Personal Rapid Transit (PRT). This alternative incorporates many of the advantages of the private motor car; yet it is cheaper, faster, less polluting, quieter, safer, more convenient and less space consuming. We will use GIS to quantitatively evaluate PRTs feasibility in Melbourne, and eventually conclude that it might be viable provided that it is implemented incrementally, and in a way that exploits current transport infrastructure. That is, we will exploit modern GIS ability to measure the lengths of linear features, to buffer, to intersect, to plot standard-deviation ellipses and to statistically analyse attribute tables in order to quantify PRTs costs, as well as some of its benefits, at different localities, thereby suggesting places where PRT might best be trialled.

description: This report gives an overview about certain aspects of modern reproductive medicine. The following issues are prioritised: development of medical facilities, people’s knowledge on reproductive medicine, appraisal of chances and risks, psychological aspects of involuntary childlessness, stresses and strains during IVFtreatment, ethical consequences of these medical procedures. Furthermore interactions between demographic and medical developments are analysed as well as resulting psychological and sociological perspectives. Previous research results present both a lack of knowledge towards reproductive medical treatments and disproportionate expectations and hope toward treatment-outcome. Very often expensive and complex methods are practiced to fulfil the child wish, but mental and social aspects remain unconsidered. So the motto “a child at any cost” on the part of many involuntary childless couples as well as of some fertility doctors poses a glaring contradiction to insufficient counselling in practice prior to, during and after the treatment. Zusammenfassung Der vorliegende Artikel soll einen Überblick über verschiedene Aspekte der modernen Reproduktionsmedizin ermöglichen. Auf folgende Schwerpunkte wird deshalb genauer eingegangen: Entwicklung der medizinischen Möglichkeiten, Wissen in der Bevölkerung, Einschätzung von Chancen und Gefahren, psychologische Aspekte der Kinderlosigkeit, Belastungen während einer IVF-Behandlung, ethisch-moralische Konsequenzen der Verfahren. Darüber hinaus werden Zusammenhänge zwischen demographischer und medizinischer Entwicklung sowie die sich daraus ergebenden spezifischen psychologischen und soziologischen Perspektiven aufgezeigt. Die bisherigen Forschungsergebnisse zeigen nicht nur ein Mangel an Wissen bzgl. fortpflanzungsmedizinischer Aspekte, sondern auch übertrieben große, zum Teil unberechtigte, Hoffnungen hinsichtlich der Wirksamkeit der reproduktionsmedizinischen Verfahren. Oftmals werden hochaufwändige und kostenintensive Verfahren eingesetzt, um den (langen) Wunsch nach einem Kind zu erfüllen, allerdings ohne psychischen und sozialen Wirkfaktoren Rechnung zu tragen. Somit steht die Devise "ein Kind um jeden Preis" seitens vieler Paare und aber auch Reproduktionsmediziner im krassen Gegensatz zu mangelnder Beratung vor, während und nach einer Behandlung.

description: We demonstrate that certain class of infinite sums can be calculated analytically starting from a specific quantum mechanical problem and using principles of quantum mechanics. For simplicity we illustrate the method by exploring the problem of a particle in a box. Twofold calculation of the mean value of energy for the polynomial wave function inside the well yields even argument $p$ ($p>2$) of Riemann zeta and related functions. This method can be applied to a wide class of exactly solvable quantum mechanical problems which may lead to different infinite sums. Besides, the analysis performed here provides deeper understanding of superposition principle and presents useful exercise for physics students.

description: We include effects of chiral symmetry and its restoration in the kinetic equations for baryon propagation and explore the consequences for $η$, $π^0$, $ρ$ and dilepton production in heavy-ion collisions at 1-2A GeV. Numerical calculations are performed using the GiBUU microscopic transport model supplemented by the parity-doublet model for the mean fields of the nucleon and the $N^*(1535)$ resonance. In this chiral model, a strong dropping of the Dirac mass of the $N^*(1535)$ in the high-density stage of a collision leads to a considerable enhancement in the production of this resonance as compared to the standard (non-linear) Walecka model. As the system expands, the Dirac masses of these abundant soft $N^*(1535)$ resonances gradually increase and ultimately cross the $N η$ decay threshold. As a result, an enhanced low-energy $η$ production is observed in the calculations with chiral mean fields. Comparing with TAPS data on $η$ and $π^0$ production we find that the chiral model improves the agreement for the $m_t$-spectra of $η$'s at small $m_t$ in heavy colliding systems. A similar enhancement is also observed in the soft $ρ$ production due to chiral symmetry and its partial restoration. The resulting dilepton yields at low and intermediate invariant masses are slightly enhanced due to these chiral effects which further improve the agreement between GiBUU transport simulations and HADES data for C+C at 1A GeV.

description: This study examines the question to which extent lifestyle features such as a family or career orientation may independently predict the transition from cohabitation into the first marriage. The results have shown that regarding marriage behaivour the lifestyle features neither represent simple reflexes of other sociostructural factors such as age, education or professional status nor are they independent of those. A family-oriented and religious lifestyle is positively linked to the probability of marriage – even when controlling for education level, formal religious affiliation and other features. Negative effects of a career- and leisure-oriented lifestyle of the woman on the transition rate, however, can be explained by education, professional status and family formation. Furthermore, it is relevant to which extent certain lifestyle features are shared between the partners. The probability of marriage tends to increase with an increasing career orientation of the male cohabitor in relation to the female cohabitor. In contrast, it decreases if the partners’ family orientation is different. Zusammenfassung Es wird der Frage nachgegangen, inwieweit Lebensstilmerkmale wie eine Familien-, Freizeit- oder Berufsorientierung eigenständig den Übergang von der nichtehelichen Lebensgemeinschaft in die erste Ehe erklären können. Die Ergebnisse zeigen, dass die Lebensstilelemente im Hinblick auf das Heiratsverhalten weder einfache Reflexe anderer soziostruktureller Merkmale wie Alter, Bildung oder Erwerbsstatus darstellen, noch von diesen unabhängig sind. Zwischen einem häuslich-familienorientierten sowie religiösen Lebensstil und der Heiratswahrscheinlichkeit bestehen (geschlechtsunspezifisch) auch dann positive Zusammenhänge, wenn das Bildungsniveau, die formale Konfessionszugehörigkeit und weitere Merkmale kontrolliert werden. Die negativen Effekte eines berufs- und freizeitorientierten Lebensstils der Frau auf die Übergangsrate lassen sich dagegen durch das Bildungsniveau, den Erwerbsstatus und die Familiengründung erklären. Darüber hinaus ist relevant, wie bestimmte Lebensstilmerkmale innerhalb des Paares verteilt sind. Die Heiratswahrscheinlichkeit steigt tendenziell bei einer relativ zur Frau ansteigenden Berufsorientierung des Mannes. Sie sinkt dagegen, wenn sich die Familienorientierung der Partner unterscheidet.

The Missing vox populi: navigating the lives of the commoners in classical literature
Creators: name: Markellos, Nicholas P.

description: For thousands of years, people have read and enjoyed classical works of literature, and for the most part, these stories have focused on the lives of the rich and the famous. That is, throughout these stories, we see petty kings dot the Trojan landscape and engage in epic battles in Homer’s The Iliad, and a motley assortment of plutocrats fight over the hand of Penelope in Odysseus’ absence. Virgil, too, tells of a Trojan prince in the Aeneid, who emigrates out of a burning city and falls in love with a widowed queen, only to leave her and then grapple with indigenous kings over territorial claims in Italy. While the lives of the aristocrats certainly dominate the scenes in the epics, there are a host of references both in the text as well as the subtext that suggest how integral the commoners were at that time. In this research, I argue that navigating the lives of the plebeian characters through classical works of literature can reveal the missing voices of these underprivileged people of this period, as well as provide a new way to approach the literature and history of classical civilization.

description: In this work we study a model of opinion dynamics considering activation/deactivation of agents. In other words, individuals are not static and can become inactive and drop out from the discussion. A probability $w$ governs the deactivation dynamics, whereas social interactions are ruled by kinetic exchanges, considering competitive positive/negative interactions. Inactive agents can become active due to interactions with active agents. Our analytical and numerical results show the existence of two distinct nonequilibrium phase transitions, with the occurrence of three phases, namely ordered (ferromagnetic-like), disordered (paramagnetic-like) and absorbing phases. The absorbing phase represents a collective state where all agents are inactive, i.e., they do not participate on the dynamics, inducing a frozen state. We determine the critical value $w_c$ above which the system is in the absorbing phase independently of the other parameters. We also verify a distinct critical behavior for the transitions among different phases.

description: Tailored topological stabilizer codes in two dimensions have been shown to exhibit high storage threshold error rates and improved subthreshold performance under biased Pauli noise. Three-dimensional (3D) topological codes can allow for several advantages including a transversal implementation of non-Clifford logical gates, single-shot decoding strategies, parallelized decoding in the case of fracton codes as well as construction of fractal lattice codes. Motivated by this, we tailor 3D topological codes for enhanced storage performance under biased Pauli noise. We present Clifford deformations of various 3D topological codes, such that they exhibit a threshold error rate of 50% under infinitely biased Pauli noise. Our examples include the 3D surface code on the cubic lattice, the 3D surface code on a checkerboard lattice that lends itself to a subsystem code with a single-shot decoder, the 3D color code, as well as fracton models such as the X-cube model, the Sierpinski model and the Haah code. We use the belief propagation with ordered statistics decoder (BP-OSD) to study threshold error rates at finite bias. We also present a rotated layout for the 3D surface code, which uses roughly half the number of physical qubits for the same code distance under appropriate boundary conditions. Imposing coprime periodic dimensions on this rotated layout leads to logical operators of weight O(n) at infinite bias and a corresponding exp[−O(n)] subthreshold scaling of the logical failure rate, where n is the number of physical qubits in the code. Even though this scaling is unstable due to the existence of logical representations with O(1) low-rate Pauli errors, the number of such representations scales only polynomially for the Clifford-deformed code, leading to an enhanced effective distance.

description: A physics-informed neural network (PINN), which has been recently proposed by Raissi et al [J. Comp. Phys. 378, pp. 686-707 (2019)], is applied to the partial differential equation (PDE) of liquid film flows. The PDE considered is the time evolution of the thickness distribution $h(x,t)$ owing to the Laplace pressure, which involves 4th-order spatial derivative and 4th-order nonlinear term. Even for such a PDE, it is confirmed that the PINN can predict the solutions with sufficient accuracy. Nevertheless, some improvements are needed in training convergence and accuracy of the solutions. The precision of floating-point numbers is a critical issue for the present PDE. When the calculation is executed with a single precision floating-point number, the optimization is terminated due to the loss of significant digits. Calculation of the automatic differentiation (AD) dominates the computational time required for training, and becomes exponentially longer with increasing order of derivatives. By splitting the original 4th-order one-variable PDE into 2nd-order two-variable PDEs, the computational time for each training iteration is greatly reduced. The sampling density of training data also significantly affects training convergence. For the problem considered in this study, mproved convergence was obtained by allowing the sampling density of training data to be greater in earlier time ranges, where the rapid flattening of the thickness occurs.

description: Conservation of historic cities is limited in many countries to valorization and safeguarding which is performed utilizing several types of interventions. Many countries aware of the importance of their heritage in the development of human life, are currently concerned with their inhabitants’ participatory role in conservation. The historic cities in Algeria are not immune to this fact. Nowadays, particular attention is paid to the quality of life in historic Algerian cities which are in continuous transformation. It has become an urgent issue to inquire into the state of these medinas. The aim of this article is to design an analysis grid of habitability for these historical cities in order to interpret the quality of life, as well as the understanding of the man-made quest for ideal livability. The adopted methodology is divided into two parts: first, making the grid and second, its projection and analysis. Application of the grid requires very diverse data and a field of study. For this purpose, several tools were mobilized: a questionnaire survey, field measurements and direct diagnosis. For a positive outcome to the research, fieldwork is essential. This is the case study of the Medina of Mostaganem.

description: Interlineage communication within a cancer microenvironment can augment cancer cell behaviour and impact response to therapy. Patient-derived cancer organoids provide an opportunity to explore cancer cell biology, however it is a major challenge to generate a complex cancer microenvironment in vitro. Here, we established a stromal tumoroid culture system modeling pancreatic ductal adenocarcinoma (PDAC) that reconstitutes multilineage interactions between cancer, endothelial, and fibroblast cells and recapitulates several aspects of primary tumors. Whole-mount immunohistochemistry on cleared tumoroids reveals organized vessel, desmoplastic fibroblast, and glandular cancer cell phenotypes that emerge over time. Time-course scRNA-seq measurements show that tumoroid formation activates fibroblasts, altering the extracellular matrix (ECM) composition and inducing cancer cell signal-response signatures and metabolic state change. Comparison between tumoroids with normal or cancer associated fibroblasts (CAFs) reveals different ECM compositions, as well as differential effects on cancer cell behaviors and metabolism. We identify Syndecan 1 (SDC1) and Peroxisome proliferator-activated receptor gamma (PPARG) as receptor and metabolic nodes involved in cancer cell response to CAF signals, and blocking SDC1 disrupts cancer cell growth within the tumoroid. Tumoroids from multiple PDAC patients revealed co-existence of subpopulations associated with classical and basal phenotypes, and CAF-induced migration behaviors emerged in certain patient tumoroids. Comparisons between patient tumoroids revealed a multigene migration signature that develops over time reflecting a stress response mechanism that correlates with worse clinical outcome. Altogether, stromal tumoroids can be used to explore dynamic and reciprocal interactions between cancer, CAF and endothelial cell states, and our data provides new inroads into the discovery of personalized pancreatic cancer therapies.
