A Study on Traditional Asian Gardens as Parts of Water Network
Creators: name: Ono, Akihiko
Publisher: name: SPOOL
Year: 2020

description: This research aims to reveal the workings of hybrid systems with ornamental garden ponds and functional water systems in historical Japanese garden cities through researching old maps, documents, and measuring canals and garden ponds in three old cities (Edo/ Tokyo, Kanra-Gunma, and Kojirokuji-Nagasaki). As a result, the following things became clear: (1) If more than 50% of canals run through private land, canals are complicatedly divided to reduce quantitative (flood and drought) and qualitative (pollution) risk; (2) Lords of these cities lived at the termination points of the systems to control the water quality of the entire water networks; (3) In most cases, canals are not directly connected to garden ponds. In the few cases in which garden ponds have the functionality to control amounts of water downstream or upstream, garden ponds are directly connected; (4) Garden design variety becomes richer in accordance with the topographical situation; (5) In gardens, canals are divided into different uses; ornamental use and practical use for daily life.

description: Aim: To assess whether performing routinely 2-deoxy-2- [18F]fluoro-D-glucose PET/CT (18FDG PET/CT) scan from the upper thigh to the vertex of skull is clinically relevant. Materials and Methods: 3502 (1634 female; mean-age 60+16) consecutive patients undergoing 18FDG PET/CT were retrospectively analyzed. Patients were divided in 10 groups according to primary malignancy. Chi-square analysis was used to assess differences among proportions. A p value < 0.05 was considered significant. Results: 18FDG PET/CT was positive in head district in 130/3502 (3,7%) patients. In all patients lesions were unknown before PET/CT examination. PET/CT showed 158 positive brain/head uptake in the 130 patients. The 158 lesions were localized in: brain (43/158; 27%), bone (52/158; 33%), lymph node (1/158; 0,6%), soft tissue (55/158; 35%) and other sites (7/158; 4,4%). According to each group, patients were positive in the head district in 1.0% for Gastrointestinal Cancer (7/690), 3.0 % for Genitourinary Cancer (3/101), 3.7 % for Haemathologic Cancer (59/1590), 2.7 % for Gynaecologic Cancer (3/112), 7.8% for Head-Neck-Thyroid and Parathyroid Cancer (26/331), 3.5% for Breast Cancer (7/200), 2.6% for Lung Cancer (7/271), 3.4% for Melanoma (2/59), 7.4% for Sarcoma (2/27), 11.6% for Unknown Primary Tumour (14/121). Conclusion: Our data show a relatively high incidence of brain/head lesion in patients with Unknown Primary Tumour.

description: Rapid urbanisation and sprawling growth have become constant hindrances to nature in most developing countries. West Java is the most populated province in Indonesia under rapid urbanisation. In this rural area of the province, however, there is a traditional Sundanese hamlet called Kampung Naga that has succeeded in cohesively cohabiting with nature. This article discusses how the interaction of water, ecology, and anthropo-systems influences the spatial layout of the village, forms its cultural landscape, and shapes people’s social life. In addition to its sustainability, this article also reflects on the challenges of the possible application of this heritage landscape system in wider contexts. Three lessons can be learned from the water heritage system of Kampung Naga: (1) Understanding how the workings of the natural landscape are critical in determining the living space development; (2) The circular water system and its metabolism could only be maintained by integrating it into its cultural, social, and economical values; (3) Community planning and water circularity create a self-sustained living unit in Kampung Naga. Findings from this study can improve our body of knowledge of potential solutions for future spatial development, where the relationship between human and water could be profoundly re-established.

description: Accurate delineation of pathological lungs from computed tomography (CT) images remains mostly unsolved because available methods fail to provide a reliable generic solution due to high variability of abnormality appearance. Local descriptor-based classification methods have shown to work well in annotating pathologies; however, these methods are usually computationally intensive which restricts their widespread use in real-time or near-real-time clinical applications. In this paper, we present a novel approach for fast, accurate, reliable segmentation of pathological lungs from CT scans by combining region-based segmentation method with local descriptor classification that is performed on an optimized sampling grid. Our method works in two stages; during stage one, we adapted the fuzzy connectedness (FC) image segmentation algorithm to perform initial lung parenchyma extraction. In the second stage, texture-based local descriptors are utilized to segment abnormal imaging patterns using a near optimal keypoint analysis by employing centroid of supervoxel as grid points. The quantitative results show that our pathological lung segmentation method is fast, robust, and improves on current standards and has potential to enhance the performance of routine clinical tasks.

Mapping the Maritime Backyards of Póvoa de Varzim
Creators: name: Fernandes, José Pedro

Publisher: name: SPOOL
Year: 2020

description: In order to improve their professional activity, fishermen have developed special methods and procedures for organising the space of their maritime territory. This article presents some of these practices, based on the specific case of the fishing community of Póvoa de Varzim, a town on the north coast of Portugal. Over the years, each fishing family has developed mental maps of the “seas”, creating original names to identify certain places and their different characteristics, while simultaneously producing a remarkable intangible heritage. Together with the productive transformations that were characteristic of industrialisation, traditional fishing methods have also gradually changed, incorporating the use of electronic navigation devices and other mechanisms for the detection of marine resources. In this way, the sea has begun to be mapped digitally through a system of “maritime backyards” that divide the space according to the fishing gear used. The aim of this work is to map and compare the maritime space produced by traditional fishing methods and by the contemporary system of “maritime backyards”, giving visibility to practices and territories that are normally absent from the representations of places.

Visual Water Biography
Creators: name: Bobbink, Inge
name: Loen, Suzanne
Publisher: name: SPOOL
Year: 2020

description: The supervision of water systems in many countries is centralised and taken over from local water management collectives of ‘water workers’ by governmental or other water management institutions. Communities are literally and figuratively cut-off from ‘their’ water systems, due to the increase of urbanisation and industrialisation. On account of water management, humankind changed from communities of actively engaged water workers into passive users. In so doing, crucial knowledge about how communities created, maintained, and expanded ‘living water systems’, such as rice terraces, low-pasture systems, polders, floating-gardens, brooks-mill, and tidal systems, is rapidly diminishing. Revealing stories (oral accounts) of water workers generate insights and understanding of forgotten aspects of the landscape. They hold information on how to engage with water in a more holistic way, strategies that might help in facing today’s challenges. The world in general, but planners, spatial designers, and water managers working with water, in particular, have so far taken little account of these stories. Without documenting stories that are about the dynamic interaction between people and landscape, valuable knowledge has disappeared and continues to do so. To help to overcome this knowledge gap, to learn from the past, the Visual Water Biography (VWB) is developed. The novel method is based on the Delft layer approach in which the spatial relationship of a design and its topography is studied, and developed by many authors from the faculty of landscape architecture at TU Delft in combination with the landscape biography approach. The Visual Water Biography visualises and maps: 1) knowledge and 2) engagement of water workers by focusing on 3) circular and 4) cyclical processes that are descended in the landscape. The method developed for spatial planners, researchers, and designers explicitly allows for multi-disciplinary engagement with water workers, water professionals, people from other disciplines such as historians and ecologists, and the general public. The added value of the VWB method is shown by the case of the Dutch Sprengen and Brooks system, a water system that is well documented in terms of landscape biography but less understood as a living water system.

description: We developed a parabolic effective mass model with the aim to describe the in-plane constricted superconductivity in few-monolayer MgB$_2$. The model was employed to study a constricted quasi-$1$D superlattice with the simplest version of the Anderson approximation. Resonant Fano-Feshbach-like effect was found, between a miniband of a continuous normal state dispersion cutting across $E_F$ and a miniband of quasi-discrete dispersion, even though the latter is significantly energetically distanced from the Fermi level. The origin of the phenomenon was identified to be the presence of characteristic strongly localised eigenstates, due to the specific material parameters. Moreover, the mechanism leading to a "precursor" pseudogap region in a system with a non-zero phase difference is described, when the strength of the coupling is still not sufficient to open a superconducting gap, but enough to introduce electron-hole mixing into the system.

description: We present an explicit solution to a classic model of cell-population growth introduced by Luria and Delbrueck 70 years ago to study the emergence of mutations in bacterial populations. In this model a wild-type population is assumed to grow exponentially in a deterministic fashion. Proportional to the wild-type population size, mutants arrive randomly and initiate new sub-populations of mutants that grows stochastically according to a supercritical birth and death process. We give an exact expression for the generating function of the total number of mutants at a given wild type population size. We present a simple expression for the probability of finding no mutants, and a recursion formula for the probability of finding a given number of mutants. In the "large population-small mutation"-limit we recover recent results of Kessler and Levin for a fully stochastic version of the process.

description: By designing materials with variable stiffness, structures can adapt to various functional requirements. This paper presents variable stiffness explored in two case studies relying on an architected material approach that involved gradient pattern differentiation and freeform printing using thermoplastic polymers (TPE). The differentiated cell pattern had gradients from high to low density of cells, which facilitate variable stiffness. Numerical and experimental studies showed the potential for application of materials with variable stiffness in adaptive structures.

description: This article discusses new challenges for series development regarding the vehicle safety that arise from the recently published AEB test protocol by the consumer-test-organisation EuroNCAP for driver assistance systems [6]. The tests from the test protocol are of great significance for an OEM that sells millions of cars each year, due to the fact that a positive rating of the vehicle-under-test (VUT) in safety relevant aspects is important for the reputation of a car manufacturer. The further intensification and aggravation of the test requirements for those systems is one of the challenges, that has to be mastered in order to continuously make significant contributions to safety for high-volume cars. Therefore, it is to be shown how a simulation approach may support the development process, especially with tolerance analysis. This article discusses the current stage of work, steps that are planned for the future and results that can be expected at the end of such an analysis.

description: Mean square stability analysis of some continuous and discrete time stochastic systems is carried out in this paper. We present a general approach to mean square stability investigation of systems with multiplicative noise and apply presented theory to discretized linear oscillators as often met in Mechanical Engineering. The analysis relies on the spectral theory of positive operators. As one of the results one obtains a simple and efficient criterion to decide the question of stability of equilibria of linear systems. Conclusions for practical usage and preference of numerical methods solving stochastic differential equations (SDEs) with white noise can be drawn too. For illustration and practical meaningfulness, we describe stability domains of stochastic θ-methods in terms of parametric restrictions.

description: In the contemporary metropolitan landscape of Rotterdam, the open landscape spaces that once surrounded the city have been reduced to components in a hybrid field. When the polders were still expansive, with an omnipresent horizon, and big skies, they were depicted extensively by the Dutch landscape painter Henk Chabot (1894-1949). Chabot is the Rotterdam painter of an oeuvre that is associated with angular, realistic expressionism of many layers of paint in hard colours, who painted heavily emphasised skies over poor countryside, or monumental portraits of refugees or farmers. For fifteen years, he lived and worked in a studio by the river Rotte. Now, only a relic of the farmland where he lived remains: an interstice between motorways, recreation parks, and suburbs that seemed to be overlooked in the frenzy of urban planning processes. The reason this interstice still exists is that it has been reserved for a future motorway for the last 30 years, and in the not-so-distant future will become the tunnel entrance for the new A16 motorway. As a left-over space, the terrain seems non-descript. However, it does have the implicit characteristics of a ‘landscape theatre’: introducing the processes and the scale of landscape as self-evident elements of the city, and heralding the open polder landscape twenty minutes away. It borrows its physical boundaries from the Rotte river dyke, the heemtuin (botanical garden) adjacent to the Ommoord apartment blocks, the access road to Ommoord, the industrial estate, and residential area in Terbregge. Such a “borrowed boundary” can be seen as a defining trait of the landscape theatre. The open space that is defined by this borrowed boundary and the central point of the tunnel entrance, is a secluded, self-contained place, removed in time and space, insulated against the everyday reality and, aside from the public realm of streets, squares, and parks, from the hustle and bustle of urban life: a place “outside”.

description: The State of Tripura lies in northeast India which is considered to be one of the most seismically active regions of the world. In the present study, a realistic Probabilistic Seismic Hazard Assessment (PSHA) of Tripura State based on improved seismogenic sources considering layered polygonal sources corresponding to hypo-central depth range of 0 to 25 km, 25 to 70 km and 70 to 180 km, respectively and data driven selection of suitable Ground Motion Prediction Equations (GMPEs) in a logic tree framework is presented. Analyses have been carried out by formulating a layered seismogenic source zonation together with smooth-gridded seismicity. Using the limited accelerogram records available, most suitable GMPEs have been selected after performing a thorough quantitative assessment and thus the uncertainty in selecting appropriate GMPEs in PSHA has been addressed by combining them with proper weight factor. The computations of seismic hazard are carried out in a higher resolution of grid interval of 0.05 $\degree$ X 0.05 $\degree$. The probabilistic seismic hazard distribution in terms of Peak Ground Acceleration (PGA) and 5% damped Pseudo Spectral Acceleration (PSA) at different time periods for 10% and 2% probability of exceedance in 50 years at engineering bedrock level have been presented. The final results show significant improvements over the previous studies, which is reflecetd in the local variation of the hazard maps. The design response spectra at engineering bedrock level can be computed for any location in the study region from the hazard distributions. The results will be useful for earthquake resistant design and construction of structures in this region.

description: The foreseen Phase 2 pixel upgrades at the LHC have very challenging requirements for the design of hybrid pixel readout chips. A versatile pixel simulation platform is as an essential development tool for the design, verification and optimization of both the system architecture and the pixel chip building blocks (Intellectual Properties, IPs). This work is focused on the implemented simulation and verification environment named VEPIX53, built using the SystemVerilog language and the Universal Verification Methodology (UVM) class library in the framework of the RD53 Collaboration. The environment supports pixel chips at different levels of description: its reusable components feature the generation of different classes of parameterized input hits to the pixel matrix, monitoring of pixel chip inputs and outputs, conformity checks between predicted and actual outputs and collection of statistics on system performance. The environment has been tested performing a study of shared architectures of the trigger latency buffering section of pixel chips. A fully shared architecture and a distributed one have been described at behavioral level and simulated; the resulting memory occupancy statistics and hit loss rates have subsequently been compared.

description: The three-dimensional (3D) topological insulator (TI) is a novel state of matter as characterized by two-dimensional (2D) metallic Dirac states on its surface. Bi-based chalcogenides such as Bi2Se3, Bi2Te3, Sb2Te3 and their combined/mixed compounds like Bi2Se2Te and (Bi1-xSbx)2Te3 are typical members of 3D-TIs which have been intensively studied in forms of bulk single crystals and thin films to verify the topological nature of the surface states. Here, we report the realization of the Quantum Hall effect (QHE) on the surface Dirac states in (Bi1-xSbx)2Te3 films (x = 0.84 and 0.88). With electrostatic gate-tuning of the Fermi level in the bulk band gap under magnetic fields, the quantum Hall states with filling factor ν= \pm 1 are resolved with quantized Hall resistance of Ryx = h/e2 and zero longitudinal resistance, owing to chiral edge modes at top/bottom surface Dirac states. Furthermore, the appearance of a ν= 0 state (σxy = 0) reflects a pseudo-spin Hall insulator state when the Fermi level is tuned in between the energy levels of the non-degenerate top and bottom surface Dirac points. The observation of the QHE in 3D TI films may pave a way toward TI-based electronics.
Circular Water Stories

description: Professional water managers, due to a rise in population, have taken over authority of the living water systems (circular water system) in which there is a self-evident exchange between the natural system and the (human) water chain. This led to an administrative approach to the water system in many - especially western - countries. Water systems were separated into categories like drinking water, drainage, irrigation, sewage systems, and water safety systems, with centralised management. The bond that traditionally existed between communities and ‘their’ water was literally and figuratively cut off and became not only controlled from the top down, but was also often invisible, amplified by technical innovations or even more disturbingly by a lack of water. This industrialisation caused a change from communities of water workers - aware and knowledgeable about the importance of water as the source of life and shaper of the cultivated landscape - to passive users. Central to this Spool issue, Landscape Metropolis #7, are contributions that investigate traditional water systems as a source of inspiration for today’s challenges. Due to the fact that there are so many interesting contributions there is room for a second issue on: Circular Water Stories Landscape Metropolis #8, which will be published in early 2021.

Investigating the magnetic inclination angle distribution of $γ$-ray-loud radio pulsars

description: Several studies have shown the distribution of pulsars' magnetic inclination angles to be skewed towards low values compared with the distribution expected if the rotation and magnetic axes are placed randomly on the star. Here we focus on a sample of 28 $γ$-ray-detected pulsars using data taken as part of the Parkes telescope's \emph{FERMI} timing program. In doing so we find a preference in the sample for low magnetic inclination angles, $α$, in stark contrast to both the expectation that the magnetic and rotation axes are orientated randomly at the birth of the pulsar and to $γ$-ray-emission-model-based expected biases. In this paper, after exploring potential explanations, we conclude that there are two possible causes of this preference, namely that low $α$ values are intrinsic to the sample, or that the emission regions extend outside what is traditionally thought to be the open-field-line region in a way which is dependent on the magnetic inclination. Each possibility is expected to have important consequences, ranging from supernova physics to population studies of pulsars and considerations of the radio beaming fraction. We also present a simple conversion scheme between the observed and intrinsic magnetic inclinations which is valid under the assumption that the observed skew is not intrinsic and which can be applied to all existing measurements. We argue that extending the active field-line region will help to resolve the existing tension between emission geometries derived from radio polarisation measurements and those required to model $γ$-ray light curves.

description: Traditional hydraulic milling was the main productive activity in the Sierra de Cádiz (Andalusia, Spain), as evidenced by the existence of 85 mills spread throughout the region. Although the date of their construction is unknown, the first documentary evidence of their existence appeared in the 16th century. In the 18th century, a more comprehensive account of the set of mills in the Sierra was drawn up thanks to the Ensenada Cadastre. The majority were operational until the mid-20th century, albeit with some difficulties. The disappearance of this handmade trade has led to the obsolescence and abandonment of its architecture and infrastructure. However, the infrastructure remains there, as traces of a recent past in which it is still possible to see the Circular Water Story that made them work. This article explains the hydraulic system that was used by the mills in the Sierra de Cádiz. Located next to rivers and streams, they formed part of an open water re-circulation system, which captured the water at a specific point in the riverbed of origin, artificially diverted it to the mill and then ended up returning it to the same riverbed of origin, at a different point from the initial one. The methodology used is based on the preparation of graphic documents and photographic recognition to select the riverbanks that show the adaptations and variations of the water re-circulation system according to the hydrographic, topographic, and productive characteristics of each territory. As some of these old artificial riverbeds are still operational, today they are used as a natural resource to supply water to other productive activities, thus proving the usefulness of the system, the suitability of the construction techniques applied, and their consequent integration into the landscape. The research carried out justifies the need to protect and catalogue these architectural hydraulic systems before they disappear completely, in order to benefit from the learning that can be derived from the reading, interpretation, and transformation of the territory and its landscape.

description: The design of a microstructured, fully functional spin-wave majority gate is presented and studied using micromagnetic simulations. This all-magnon logic gate consists of three-input waveguides, a spin-wave combiner and an output waveguide. In order to ensure the functionality of the device, the output waveguide is designed to perform spin-wave mode selection. We demonstrate that the gate evaluates the majority of the input signals coded into the spin-wave phase. Moreover, the all-magnon data processing device is used to perform logic AND-, OR-, NAND- and NOR- operations.
