description: In order to shed light on the status and economic model of Banassac’s Early Empire terra sigillata workshop, systematic surveys were carried out on the karstic terrain of the area surrounding the town. Due to a shortage of sources, the project was carried out as an integrative ‘community archaeology’ project, from the definition of the scope of research to the drawing of conclusions and consideration of results.With the synthesis of settlement dynamics from the Mesolithic times to the Middle Ages provided by the study and precise data about occupied sites in Roman times (38 villae and 55 workshops),it is now possible to see at Banassac a villa controlling a fundus through an integrated economic system linking clay, pitch and iron.

description: Rapporto tecnico che descrive dei test di trasmissione di segnale via radio. Si è testata la possibilità di inviare da una stazione Master delle correzioni RTCM (Radio Technical Commission for Maritime), ricevute via internet tramite protocollo NTRIP (Networked Transport of RTCM via Internet Protocol), ad una stazione Slave a cui era connesso un ricevitore GNSS U Blox ZED F9P in grado così di ottenere un posizionamento RTK (real time kinematics) in real-time. Sono stati fatti anche test inserendo un Repeater tra il Master e lo Slave, per simulare il caso reale di trasmissione via radio di segnali con ostacoli. La strumentazione utilizzata, il set-up sperimentale e i test effettuati in laboratorio sono descritti in dettaglio nel rapporto tecnico.

description: Equidistant and non-equidistant single pulse "bang-bang" dynamical controls are investigated in the context of mean ergodic theorems. We show the requirements in which the limit of infinite pulse control for both the equidistant and the non-equidistant dynamical control converges to the same unitary evolution. It is demonstrated that the generator of this evolution can be obtained by projecting the generator of the free evolution onto the commutant of the unitary operator representing the pulse. Inequalities are derived to prove this statement and in the case of non-equidistant approach these inequalities are optimised as a function of the time intervals.

description: Long-range interacting systems may exhibit ensemble inequivalence and can possibly attain equilibrium states under completely open conditions, for which energy, volume and number of particles simultaneously fluctuate. Here we consider a modified version of the Thirring model for self-gravitating systems with attractive and repulsive long-range interactions in which particles are treated as hard spheres in dimension d=1,2,3. Equilibrium states of the model are studied under completely open conditions, in the unconstrained ensemble, by means of both Monte Carlo simulations and analytical methods and are compared with the corresponding states at fixed number of particles, in the isothermal-isobaric ensemble. Our theoretical description is performed for an arbitrary local equation of state, which allows us to examine the system beyond the excluded-volume approximation. The simulations confirm the theoretical prediction of the possible occurrence of first-order phase transitions in the unconstrained ensemble. This work contributes to the understanding of long-range interacting systems exchanging heat, work and matter with the environment.

description: This paper presents a new approach for the estimation of rooftop photovoltaic potentials. It extracts building footprints from OpenStreetMap and combines these with orthographic satellite images from Bing Maps. These images are analyzed using image recognition techniques in order to identify the ridge line as well as structures like chimneys and windows on each building’s roof. In combination with statistical assumptions about the roof’s inclination angle, the exact shape, size and orientation of the partial roof areas can be calculated for each building. For the resulting areas, an irradiance simulation is conducted and combined with a PV electricity yield model in order to calculate electricity generation profiles with a high spatial and temporal resolution. The main advantages of this approach over methods which typically employ 3D models are, that no resources are required for data acquisition and it can be applied worldwide. The method is applied to German cities and an evaluation indicates a success rate of over 70%.

description: We study the thermal evolution of axisymmetric rotating neutron stars in full general relativity. To this aim we develop "NSCool 2D Rot", a major upgrade of the 1D neutron stars thermal evolution code "NSCool" by D. Page. As a first application of our new code we address the standard cooling of isolated neutron stars with rotation frequencies up to the mass shedding limit. We investigate the effects of the equation of state (EOS) by considering different combinations of core and crust EOSs. The results indicate complex time-dependent evolution of temperature distribution throughout the whole volume of the star and, in particular, in the crust. We show that most of that complexity can be attributed to the formation of a "heat blob" in the crust and to the latitude dependence of the heat diffusion timescale through the crust.

Surform: An Architectural Vocabulary of Morphogenesis
Creators: name: Rees, Jack M.
Publisher: name: FOOTPRINT
Year: 2018

description: The term morphogenesis in architecture is usually associated with parametric design strategies. I intend ‘morphogenetic’ in a different sense. Architecture in general, and architectural education in particular, are awash in proposals that might be best described as ‘biomorphic.’ Yet, in my experience, students and practitioners have neither fundamental understanding of shape-as-surface nor the vocabulary necessary to describe such designs. This vocabulary, including a powerful generalisation of biomorphic shape, is readily available in the work of Carl Friedrich Gauss (1777–1855). Gauss’s generalisation recognised that there are only three types of surface: positively curved, negatively curved and surfaces of zero curvature. This paper offers a concise exposition of Gauss’s formulation, a proposal for a vocabulary sufficient to clearly discuss such shapes in design contexts and a plea for an architectural pedagogy that moves beyond notions of space as bounded emptiness (i.e. beyond perspectival constructions). These reflections are a product of an educational experiment conducted in a first year architectural studio during the spring of 2017. Surform is a neologism, shorthand for ‘shape conceived as surface.’

description: This paper proposes a new voice conversion (VC) task from human speech to dog-like speech while preserving linguistic information as an example of human to non-human creature voice conversion (H2NH-VC) tasks. Although most VC studies deal with human to human VC, H2NH-VC aims to convert human speech into non-human creature-like speech. Non-parallel VC allows us to develop H2NH-VC, because we cannot collect a parallel dataset that non-human creatures speak human language. In this study, we propose to use dogs as an example of a non-human creature target domain and define the "speak like a dog" task. To clarify the possibilities and characteristics of the "speak like a dog" task, we conducted a comparative experiment using existing representative non-parallel VC methods in acoustic features (Mel-cepstral coefficients and Mel-spectrograms), network architectures (five different kernel-size settings), and training criteria (variational autoencoder (VAE)- based and generative adversarial network-based). Finally, the converted voices were evaluated using mean opinion scores: dog-likeness, sound quality and intelligibility, and character error rate (CER). The experiment showed that the employment of the Mel-spectrogram improved the dog-likeness of the converted speech, while it is challenging to preserve linguistic information. Challenges and limitations of the current VC methods for H2NH-VC are highlighted.

description: For the environs of the Late Bronze Age fortification enclosure Iarcuri the hydro-morphological relief characteristics are combined with archaeological evidences. Target of the study is to evaluate the impact of settlement activities in the surroundings of Iarcuri on the development of the channel network. Data analysis is based on topographic map-derived and high resolution DEMs provided by LiDAR scanning; derivatives of the DEMs are used to characterize the different sub-catchments that show varying influences by the fortification ramparts. The tributaries reaching the receiving stream close to the central settlement area source close to the gates in the ramparts in the Late Bronze Age built-up areas. Additionally, also the geometry of these tributaries differs from that of other tributaries. The distinct character of the channel network with repeatedly occurring rectangular bends indicates the capture of channels, which developed as gullies along paths by retrogressive erosion.

description: We present a large-scale combination of near-infrared (near-IR) interstellar polarization data from background starlight with polarized emission data at submillimeter (sub-mm) wavelengths for the Vela C molecular cloud. The near-IR data consist of more than 6700 detections probing a range of visual extinctions between $2$ and $20\,$mag in and around the cloud. The sub-mm data was collected in Antartica by the Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry (BLASTPol). This is the first direct combination of near-IR and sub-mm polarization data for a molecular cloud aimed at measuring the "polarization efficiency ratio" ($R_{\mathrm{eff}}$), a quantity that is expected to depend only on grain intrinsic physical properties. It is defined as $p_{500}/(p_{I}/τ_{V})$, where $p_{500}$ and $p_{I}$ are polarization fractions at $500\,μ$m and $I$-band, respectively, and $τ_{V}$ is the optical depth. To ensure that the same column density of material is producing both polarization from emission and from extinction, we conducted a careful selection of near-background stars using 2MASS, $Herschel$ and $Planck$ data. This selection excludes objects contaminated by the Galactic diffuse background material as well as objects located in the foreground. Accounting for statistical and systematic uncertainties, we estimate an average $R_{\mathrm{eff}}$ value of $2.4\pm0.8$, which can be used to test the predictions of dust grain models designed for molecular clouds when such predictions become available. $R_{\mathrm{eff}}$ appears to be relatively flat as a function of the cloud depth for the range of visual extinctions probed.

description: Photovoltaic (PV) technologies constitute a leading renewable energy source with a worldwide installed capacity of 135 GW in 2013 that may increase to nearly 4700 GW in 2050. To achieve this production level while minimizing environmental impacts, decision makers must rely at national level on relevant technological, economic and planning aspects which are highly geographically dependent. The access to performance data is a critical issue in the decision-making process and determines the successful development of efficient PV systems. For this reason, a new interactive tool is proposed here to provide the users with easy-to-use data and maps for the solar irradiation and screening level environmental results of representative PV technologies. The calculation procedures account for the geographic location and the PV system layout (installation, orientation and inclination angles). The tool has a worldwide coverage with a multi-criteria scope, both in terms of the numerous technological scenarios and of the wide range of environmental indicators. Moreover, the user is given the possibility to compare the PV environmental performance to the corresponding country electricity mix environmental footprint.

description: Within Process mining, discovery techniques had made it possible to construct business process models automatically from event logs. However, results often do not achieve the balance between model complexity and its fitting accuracy, so there is a need for manual model adjusting. The paper presents an approach to process mining providing semi-automatic support to model optimization based on the combined assessment of the model complexity and fitness. To balance between the two ingredients, a model simplification approach is proposed, which essentially abstracts the raw model at the desired granularity. Additionally, we introduce a concept of meta-states, a cycle collapsing in the model, which can potentially simplify the model and interpret it. We aim to demonstrate the capabilities of the technological solution using three datasets from different applications in the healthcare domain. They are remote monitoring process for patients with arterial hypertension and workflows of healthcare workers during the COVID-19 pandemic. A case study also investigates the use of various complexity measures and different ways of solution application providing insights on better practices in improving interpretability and complexity/fitness balance in process models.

description: Since uncertainty is part and parcel of archaeology, using the scientific method to reconstruct historical processes is an absolute priority. This is even truer for prehistoric contexts, where human traces on the territory are ephemeral and less invasive. Working on prehistoric landscapes presents the researcher with complex methodological issues that must be dealt with. GIS technology is a leading method of highlighting the elements that condition settlement choices; it clarifies the interaction among different types of sources and increases their informative potential. This contribution describes the methodological workflow we applied to deal with such issues through a case study of settlement strategies during the Bronze Age in Tuscany, Italy.

description: Within the color singlet model, we calculate the exclusive production of double charmonia, double bottomonia, and double $B_c$ mesons at future super $Z$ factory. The two heavy quarkonia or $B_c$'s are either two S-wave Fock states ($^1S_0, ~^3S_1$), or one S-wave and one P-wave states ($^1P_1,~^3P_J~(J=0,1,2)$). The top three $Z^0$ propagated channels in cross sections for double charmonia are $J/ψ+h_c,η_c+χ_{c2}$, and $η_c+χ_{c0}$. For double bottomonia, they are $η_b+Υ, Υ+χ_{b2}$, and $Υ+Υ$. For double $B_c$ mesons, they are $B_c^{*+}+B_c^{*-}$,$B_c^{*+}+χ_{bc2}^-$, and $η_{bc}^++B_c^{*-}$. The cross sections of double $B_c$ mesons are roughly one order of magnitude larger than those of the double bottomonia, and two orders of magnitude larger than those of the double charmonia. To make it helpful for experimental study, we present the total cross sections $σ$ as functions of CM energy $\sqrt{s}$, $σ$ as functions of the renormalization scale $μ$, the angle distributions $dσ/dcosθ$, and the $p_T$ distributions $dσ/dp_{t}$. The uncertainties come from the varying masses of constituent heavy quarks bring up to 20% corrections. We also find that the initial state radiation can bring about 30%$\sim$40% suppresions when 1\%$m_Z$ energy is losing, and cross sections can increase by about $2\sim3$ times or decrease by an order of magnitude when adopting different potential models which becomes the major source of uncertainty. The numerical results show that it might be not optimistic for the experimental observation, but it is still far from excluded at the FCC-ee and also the CEPC running in the $Z$ factory mode.

description: Following the conclusions of the successful task on Urban scale PV systems (Task 10) of the
Photovoltaic Power System Program (PVPS) of the International Energy Agency (IEA), a pro-PV local building
policy has been set-up for the purpose of the Lyon-Confluence urban project, a 150 ha redevelopment in the city
center of Lyon, France, in order to make real-estate developers and architects design and build low energy buildings
equipped with PV systems. This pro-PV local building policy was first tested in 2004 within the EC funded
CONCERTO initiative by SPL Lyon-Confluence, the public company in charge of this redevelopment, for the
construction of the first dwellings and office spaces of the area (A, B and C blocks). Now, with 10 blocks of the
Lyon-Confluence area already equipped with one or several PV systems for a total power of 1.1 MW, this pro-PV
local building policy has been improved and the use of PV will increase with more and larger systems. Thus, 6 other
buildings will soon be equipped with PV systems for an additional power of more 1,2 MWp that will make the Lyon-
Confluence area a significant solar city showcase.

description: In der ägyptologischen Forschung werden Ortsnamen als Quellen für Raumwissen – besonders im Zusammenhang mit Konzepten wie Ausland und Urbanität – herangezogen. Dies stützt sich auf die Variation von Klassifikatoren (traditionell Determinative) in der Schreibung von Namen von Orten im ägyptischen Grenzgebiet. Derselbe Ortsname kann sowohl mit der Hieroglyphe (Gardiner-Zeichenliste O49) – mit den Konzepten städtisch und ägyptisch assoziiert – als auch mit (Gardiner-Zeichenliste N25) bzw. (Gardiner-Zeichenliste T14) – die mit dem Konzept Ausland verbunden werden – belegt sein. Diese Variation wird in Bezug zu historisch-politischen oder konzeptionellen Veränderungen des Grenzgebiets von Ägypten und u. a. der Levante gesetzt. Theorien sprachlicher Kategorisierung wurden bislang nicht einbezogen. Klassifikatoren sind aber vor allem sprachliche Elemente (Morpheme). Deswegen wird mein Beitrag exemplarisch anhand von hieroglyphischen und hieratischen Schreibungen des Namens der Stadt Sile (Tjaru) im nordöstlichen Nildelta diskutieren, wie mithilfe solcher Ansätze, insbesondere der Prototypentheorie, scheinbare Widersprüche in der Quellenlage aufgelöst werden können.
description: City names have been used as sources for knowledge of space in Egyptological research – especially with reference to concepts such as abroad and urbanity. This interpretation is based on classifier variation in the spelling of place names in the Egyptian border regions, e. g., the same name can be spelled with the hieroglyph (Gardiner's sign list O49) – associated with the concepts urban and Egyptian – as well as with (Gardiner's sign list N25) and (Gardiner's sign list T14) respectively, that are linked to the concept abroad. A relationship between this variation and historical-political or conceptional changes in the border area of Egypt and (amongst others) the Levant has been thereby established. Theories of linguistic categorization have not as yet been applied to the material, although classifiers are linguistic elements (morphemes). My contribution thus demonstrates how categorization approaches, especially prototype theory, can help reconcile seemingly contradictory data. The hieroglyphic and hieratic spelling of the Egyptian city Sile (Tjaru) will serve as an example.

description: The colliding flows (CF) model is a well-supported mechanism for generating molecular clouds. However, to-date most CF simulations have focused on the formation of clouds in the normal-shock layer between head-on colliding flows. We performed simulations of magnetized colliding flows that instead meet at an oblique-shock layer. Oblique shocks generate shear in the post-shock environment, and this shear creates inhospitable environments for star formation. As the degree of shear increases (i.e. the obliquity of the shock increases), we find that it takes longer for sink particles to form, they form in lower numbers, and they tend to be less massive. With regard to magnetic fields, we find that even a weak field stalls gravitational collapse within forming clouds. Additionally, an initially oblique collision interface tends to reorient over time in the presence of a magnetic field, so that it becomes normal to the oncoming flows. This was demonstrated by our most oblique shock interface, which became fully normal by the end of the simulation.

PV Applications Without a Centralised Grid

description: 32nd European Photovoltaic Solar Energy Conference and Exhibition; 2823-2826
description: In this paper we explore how PV powered products have been designed in the past. For this purpose we
have drawn a historical time line of the design features of PV powered products in the context of main stream design
and styling. Our time frame is 1970 till 2016, focusing in first instance on consumer products and PV powered lamps.
We will discuss how we learn from these experiences for the design and styling of future PV powered products.
Because design and styling is considered one of the key features to a well-designed product, this study is relevant for
the acceptability of PV products in nowadays consumer markets. Despite many studies on the technical functioning
and energy performance of PV powered products, little attention has been paid to a constructive analysis of design
and styling. Therefore with this study we make a start with identifying which design and styling factors can
contribute to a higher appreciation for PV powered products.

description: The provision of accurate localization is an increasingly important feature of wireless networks. To this end, a reliable distinction between line-of-sight (LOS) and non-LOS (NLOS) radio links is necessary to avoid degenerative localization estimation biases. Interestingly, LOS and NLOS transmissions affect the polarization of the received signals differently. In this work, we leverage this phenomenon to propose a threshold-based LOS/NLOS classifier exploiting weighted differential carrier phase measurements over a single link with different polarization configurations. Operation in either full or limited polarization diversity systems is possible. We develop a framework for assessing the performance of the proposed classifier, and show through simulations the performance impact of the reflecting materials in NLOS scenarios. For instance, the classifier is far more efficient in NLOS scenarios with wooden reflectors than in those with metallic reflectors. Numerical results evince the potential performance gains from exploiting full polarization diversity, properly weighting the differential carrier phase measurements, and using multi-carrier/tone transmissions. Finally, we show that the optimum decision threshold is inversely proportional to the path power gain in dB, while it does not depend significantly on the material of potential NLOS reflectors.

description: When photovoltaic (PV) projects are developed and constructed for investment purposes, financing from
professional investors and banks are required, and financial models are developed that describe the expected cash-flow
generated by the PV plant over the economic lifetime of the project. The calculation is based on models that require both
technical and financial inputs. In this paper we will review and analyse the technical assumptions in these models and
discuss how the technical assumptions are typically used and to what extent the uncertainty related to the input
parameters are appropriately addressed. Finally, a calculation and visualisation method is presented that highlights the
nature and effect of this uncertainty.

description: Many enumeration problems in combinatorics, including such fundamental questions as the number of regular graphs, can be expressed as high-dimensional complex integrals. Motivated by the need for a systematic study of the asymptotic behaviour of such integrals, we establish explicit bounds on the exponentials of complex martingales. Those bounds applied to the case of truncated normal distributions are precise enough to include and extend many enumerative results of Barvinok, Canfield, Gao, Greenhill, Hartigan, Isaev, McKay, Wang, Wormald, and others. Our method applies to sums as well as integrals. As a first illustration of the power of our theory, we considerably strengthen existing results on the relationship between random graphs or bipartite graphs with specified degrees and the so-called $β$-model of random graphs with independent edges, which is equivalent to the Rasch model in the bipartite case.

description: Objectives: To examine whether exogenous pulmonary surfactants (exPS) substitute for or merely supplement endogenous pulmonary surfactants (enPS) by looking at sequential changes in the surfactant proteins (SP) SP-A and SP-D in alveolar pools. Methods: Fourteen preterm infants with RDS treated with an artificial surfactant were compared to five normal-term infants without RDS who were treated with artificial ventilation at birth. Results: Immediately after birth, SP-A and SP-D were essentially absent in the alveolar pools of the RDS group, but were present at normal levels in the controls. Treatment with exPS apparently stimulated enPS production. Conclusions: In infants who responded well to exPS therapy, the SP concentration reached essentially normal levels within 48–72 h after birth.

PV Economics and Markets

description: Marketing PV electricity increasingly becomes a challenge as the feed-in tariff schemes are blocked, either by overbooking or by political actions against a higher contribution of electricity from PV. Self-consumption of PV electricity is, therefore, imperative. Moreover, it is economically attractive as current electricity costs from PV are about 0.25€/ kWh (or even below). However, most private households are relatively small consumers as compared to the production power of their PV installation. This is especially the case from spring to autumn, when surplus electricity is produced from the PV installations. To optimize the own consumption during this “high production mode”, it makes sense to install a battery with a 10-20 kWh storage capacity. When additional, strong electricity consumers like heating and hot water systems with heat pumps are connected, the leverage effect is increased and burning of fossil fuel can be avoided. Yet, heating is mostly needed in the cold season, when PV installations have less overproduction. The most efficient all-year strong electricity consumer is an electric vehicle (EV). Having evolved from pioneering solar cars in the mid-1980s, EVs today offer an astonishing high economic benefit as PV electricity consumers. Even more so in the near future, when EV batteries (40kWh and larger) will serve to handle the electric load management and internal combustion engines will, by 2050, entirely be replaced by EVs (International Energy Agency scenario).

description: Layered ferromagnets are thrilling materials from both a fundamental and technological point of view. VI3 is an interesting example, with a complex magnetism that differentiates it from the first reported Cr based layered ferromagnets. Here, we show in an indirect way through Angle Resolved Photoemission Spectroscopy (ARPES) experiments, the importance of spin-orbit coupling setting the electronic properties of this material. Our light polarized photoemission measurements point to a ground state with a half-filled e'_+- doublet, where a gap opening is triggered by spin-orbit coupling enhanced by electronic correlations.

description: Parallel “polystring” connection of CIGS module strings of four different orientations (south, west, north, east) to a common single-MPP inverter in a vertical façade PV system has been simulated, taking into account the influence of irradiance and module temperature on MPP voltage. The MPP voltage increases with irradiance but decreases with the increasing temperature that follows from higher irradiance. It was found that these two effects compensate each other very well over a wide irradiance range. Accordingly, the overall annual DC energy yield loss caused by voltage mismatch is only around 1 % compared to the standard setup where different orientations are connected to separate MPP trackers or inverters. Hence the system configuration can be designed with a reduced number of inverters and at reduced costs. Since the four sides of such a PV system never see sunlight all at the same time, the polystring configuration has the additional advantage that the inverter(s) can be chosen much smaller; the simulation shows that only about half as much inverter power is required as for the conventional separate-inverters-per-orientation setup. All in all, parallel connection of different orientations is an advantageous option that offers economic benefits in façade and other systems.

description: The kinematic plane of stars near the Sun has proven an indispensable tool for untangling the complexities of the structure of our Milky Way (MW). With ever improving data, numerous kinematic "moving groups" of stars have been better characterized and new ones continue to be discovered. Here we present an improved method for detecting these groups using MGwave, a new open-source 2D wavelet transformation code that we have developed. Our code implements similar techniques to previous wavelet software; however, we include a more robust significance methodology and also allow for the investigation of underdensities which can eventually provide further information about the MW's non-axisymmetric features. Applying MGwave to the latest data release from Gaia (DR3), we detect 47 groups of stars with coherent velocities. We reproduce the majority of the previously detected moving groups in addition to identifying three additional significant candidates: one within Arcturus, and two in regions without much substructure at low $V_R$. Finally, we have followed these associations of stars beyond the solar neighborhood, from Galactocentric radius of 6.5 to 10 kpc. Most detected groups are extended throughout radius indicating that they are streams of stars possibly due to non-axisymmetric features of the MW.

description: Photovoltaic-powered reverse osmosis (PVRO) desalination can potentially be the solution to two major global issues: water and energy. This technique not only increases water supply but also decreases the dependency on fossil fuels.
The objective of the present paper deals with the design of a small-scale (20 m3/day) PVRO desalination unit, given the daily water needs, in addition to conducting an economic analysis to determine both the total investment and the specific desalination cost (MAD/m3). For this case study in Dakhla (South of Morocco) which supplies drinking water for a coastal hotel, the system configuration that has the lowest investment and specific water costs is the one with an energy recovery system and separate components. The specific energy consumption of such system was found to be 2.92 kWh/m3. The total costs over a 10-year period for this system is 1,056,024 MAD, producing water at a cost of 15.47 MAD/m3.
An effective methodology is used for determining the optimal design configuration for a PVRO desalination station. For our case study, the results show two optimal solutions, both of which operate with one machine only. The first one, which yields the lowest initial investment (828,000 MAD), consists of installing one RO machine with a nominal capacity of 36 m3/day, 23 kWp of PV power and 50.5 kWh of battery storage. The second optimal combination, which generates the lowest cost of water during 10 years (14.28 MAD/m3), consists of installing one bigger RO machine having a capacity of 72 m3/day, 32 kWp of PV power and 38.5 kWh of battery storage.

description: In this paper we present Organic Primitives, an enabling toolbox that expands upon the library of input-output devices in HCI and facilitates the design of interactions with organic, fluid-based systems. We formulated color, odor and shape changing material primitives which act as sensor-actuators that convert pH signals into human-readable outputs. Food-grade organic molecules anthocyanin, vanillin, and chitosan were employed as dopants to synthesize materials which output a spectrum of colors, degrees of shape deformation, and switch between odorous and non-odorous states. We evaluated the individual output properties of our sensor-actuators to assess the rate, range, and reversibility of the changes as a function of pH 2-10. We present a design space with techniques for enhancing the functionality of the material primitives, and offer passive and computational methods for controlling the material interfaces. Finally, we explore applications enabled by Organic Primitives under four contexts: environmental, cosmetic, edible, and interspecies.

description: In condensed matter, scattering processes determine the transport of charge carriers. In case of heterostructures, interfaces determine many dynamic properties like charge transfer and transport and spin current dynamics. Here we discuss optically excited electron dynamics and their propagation across a lattice-matched, metal-metal interface of single crystal quality. Using femtosecond time-resolved linear photoelectron spectroscopy upon optically pumping different constituents of the heterostructure we establish a technique which probes the electron propagation and its energy relaxation simultaneously. In our approach a near-infrared pump pulse excites electrons directly either in the Au layer or in the Fe layer of epitaxial Au/Fe/MgO(001) heterostructures while the transient photoemission spectrum is measured by an ultraviolet probe pulse on the Au surface. Upon femtosecond laser excitation, we analyze the relative changes in the electron distribution close to the Fermi energy and assign characteristic features of the time-dependent electron distribution to transport of hot and non-thermalized electrons from the Fe layer to the Au surface and vice versa. From the measured transient electron distribution we determine the excess energy which we compare with a calculation based on the two-temperature model and takes diffusive electron transport into account. On this basis we identify a transition from a super-diffusive to a diffusive transport regime to occur for a Au layer thickness of 20-30~nm.
