description: Object location is a crucial computer vision method often used as a previous stage to object classification. Object-location algorithms require high computational and memory resources, which poses a difficult challenge for portable and low-power devices, even when the algorithm is implemented using dedicated digital hardware. Moving part of the computation to the imager may reduce the memory requirements of the digital post-processor and exploit the parallelism available in the algorithm. This paper presents the architecture of a Smart Imaging Sensor (SIS) that performs object location using pixel-level parallelism. The SIS is based on a custom smart pixel, capable of computing frame differences in the analog domain, and a digital coprocessor that performs morphological operations and connected components to determine the bounding boxes of the detected objects. The smart-pixel array implements on-pixel temporal difference computation using analog memories to detect motion between consecutive frames. Our SIS can operate in two modes: (1) as a conventional image sensor and (2) as a smart sensor which delivers a binary image that highlights the pixels in which movement is detected between consecutive frames and the object bounding boxes. In this paper, we present the design of the smart pixel and evaluate its performance using post-parasitic extraction on a 0.35 µm mixed-signal CMOS process. With a pixel-pitch of 32 µm × 32 µm, we achieved a fill factor of 28%. To evaluate the scalability of the design, we ported the layout to a 0.18 µm process, achieving a fill factor of 74%. On an array of 320×240 smart pixels, the circuit operates at a maximum frame rate of 3846 frames per second. The digital coprocessor was implemented and validated on a Xilinx Artix-7 XC7A35T field-programmable gate array that runs at 125 MHz, locates objects in a video frame in 0.614 µs, and has a power consumption of 58 mW.

description: Single crystals of ice Ih, extracted from the subglacial Lake Vostok accretion ice layer (3621 m depth) were investigated by means of diffuse x-ray scattering and inelastic x-ray scattering. The diffuse scattering was identified as mainly inelastic and rationalized in the frame of ab initio calculations for the ordered ice XI approximant. Together with Monte-Carlo modelling our data allowed reconsidering previously available neutron diffuse scattering data of heavy ice as the sum of thermal diffuse scattering and static disorder contribution.

description: Water is an essential resource required for various human activities such as drinking, cooking, growing food, and personal hygiene. As a key infrastructure of public services, access to clean and safe drinking water is an essential factor for local socio-economic development. Despite various national and international efforts, water supply is often not guaranteed, especially in rural areas of Africa. Although many water resources are theoretically available in these areas, bodies of water are often contaminated with dangerous pathogens and pollutants. As a result, people, often women and children, have to travel long distances to collect water from taps and are exposed to dangers such as physical violence and accidents on their way. In this article, we present a socio-economic case study for rural development. We describe a drinking water treatment plant with an annual capacity of 10,950 m3 on Kibumba Island in Lake Victoria (Tanzania). The plant is operated by a photovoltaic mini-grid system with second-life lithium-ion battery storage. We describe the planning, the installation, and the start of operation of the water treatment system. In addition, we estimate the water prices achievable with the proposed system and compare it to existing sources of drinking water on Kibumba Island. Assuming a useful life of 15 years, the installed drinking water system is cost-neutral for the community at a cost price of 0.70 EUR/m3, 22% less than any other source of clean water on Kibumba Island. Access to safe and clean drinking water is a major step forward for the local population. We investigate the socio-economic added value using social and economic key indicators like health, education, and income. Hence, this approach may serve as a role model for community-owned drinking water systems in sub-Saharan Africa.

description: The charged environment within a dense plasma leads to the phenomenon of ionization potential depression (IPD) for ions embedded in the plasma. Accurate predictions of the IPD effect are of crucial importance for modeling atomic processes occurring within dense plasmas. Several theoretical models have been developed to describe the IPD effect, with frequently discrepant predictions. Only recently, first experiments on IPD in Al plasma have been performed with an x-ray free-electron laser (XFEL), where their results were found to be in disagreement with the widely-used IPD model by Stewart and Pyatt. Another experiment on Al, at the Orion laser, showed disagreement with the model by Ecker and Kröll. This controversy shows a strong need for a rigorous and consistent theoretical approach to calculate the IPD effect. Here we propose such an approach: a two-step Hartree-Fock-Slater model. With this parameter-free model we can accurately and efficiently describe the experimental Al data and validate the accuracy of standard IPD models. Our model can be a useful tool for calculating atomic properties within dense plasmas with wide-ranging applications to studies on warm dense matter, shock experiments, planetary science, inertial confinement fusion and studies of non-equilibrium plasmas created with XFELs.

description: The present study was aimed at comparing vertical and horizontal surface displacements derived from the Cosmo-SkyMED, TerraSAR-X and Sentinel-1 satellite missions for the detection of oil extraction-induced subsidence in the Tengiz oilfield during 2018–2021. The vertical and horizontal surface displacements were derived using the 2D decomposition of line-of-sight measurements from three satellite missions. Since the TerraSAR-X mission was only available from an ascending track, it was successfully decomposed by combining it with the Cosmo-SkyMED descending track. Vertical displacement velocities derived from 2D Decomposition showed a good agreement in similar ground motion patterns and an average regression coefficient of 0.98. The maximum average vertical subsidence obtained from the three satellite missions was observed to be −57 mm/year. Higher variations and deviations were observed for horizontal displacement velocities in terms of similar ground motion patterns and an average regression coefficient of 0.80. Fifteen wells and three facilities were observed to be located within the subsidence range between −55.6 mm/year and −42 mm/year. The spatial analyses in the present studies allowed us to suspect that the subsidence processes occurring in the Tengiz oilfield are controlled not solely by oil production activities since it was clearly observed from the detected horizontal movements. The natural tectonic factors related to two seismic faults crossing the oilfield, and terrain characteristics forming water flow towards the detected subsidence hotspot, should also be considered as ground deformation accelerating factors. The novelty of the present research for Kazakhstan’s Tengiz oilfield is based on the cross-validation of vertical and horizontal surface displacement measurements derived from three radar satellite missions, 2D Decomposition of Cosmo-SkyMED descending and TerraSAR-X ascending line-of-sight measurements and spatial analysis of man-made and natural factors triggering subsidence processes.

description: We discuss the homological aspects of the connection between quantum string generating function and the formal power series associated to the dimensions of chains and homologies of suitable Lie algebras. Our analysis can be considered as a new straightforward application of the machinery of modular forms and spectral functions (with values in the congruence subgroup of $SL(2,{\mathbb Z})$) to the partition functions of Lagrangian branes, refined vertex and open string partition functions, represented by means of formal power series that encode Lie algebra properties. The common feature in our examples lies in the modular properties of the characters of certain representations of the pertinent affine Lie algebras and in the role of Selberg-type spectral functions of an hyperbolic three-geometry associated with $q$-series in the computation of the string amplitudes.

description: Transparent and colorless hexagonal boron nitride (hBN) single crystals were grown from the Mg-B-N system using high-pressure high-temperature cubic anvil technique. By varying the synthesis conditions we could determine the sequence of phase transformations occurring in the Mg-B-N system, construct the pressure-temperature (P-T) phase diagram and discuss the possible growth mechanism. The largest plate-like-shaped hBN crystals with sizes up to 2.5 mm in length and up to 10 (micro)m in thickness were grown at 30 kbar and 1900-2100 °C. The hBN crystals exhibited strong, narrow diffraction peaks typical of well-ordered stacking crystal planes, with the c-axis perpendicular to the crystal face. A characteristic Raman peak observed at 1367 cm-1 with a full width at half maximum of 8 cm-1 corresponds to the E2g vibration mode and indicates the high purity and order of hBN crystals grown by this method. From the practical point of view this work can stimulate further explorations of the Mg-B-N solvent system to obtain isotopically-enriched h10BN crystals, which can act as a key element in solid-state neutron detector devices.

The Steps of Thinking: Informal Science Activities for the Social Development of People with Intellectual Disabilities.
Creators: name: De Kauwe, Vanessa
Publisher: name: The Australian National University
Year: 2023

description: Australia is at a disability crossroads and science communication has the opportunity to respond. The 2016 Senate Inquiry and currently ongoing Disability Royal Commission confirm that Australian students with intellectual disabilities (ID) have been left without the necessary personal and social tools for daily living. This is compounded by a denial of meaningful academic content, including science. Disability education appears so restrictive that it denies students the opportunity to fail, and thereby learn from mistakes and develop their skills in the same manner as the rest of society. The result is growing alienation. This thesis explores how the field of science communication could potentially help alleviate the current crisis, by assisting in the personal and social development of students with ID. The primary objective of this thesis was to develop a program of informal science activities, specifically designed to target the needs of students with ID. A further objective was to assess what impact such a program may have on the personal and social skills of these students. The methods used to address these objectives were based on six case studies of high school students with mild to moderate ID. In each case study, students participated in 10 weeks of informal science activities. Their existing personal and social skills were assessed immediately before the science program using diagnostic charts, and through interviews with their parents and teaching staff. Interviews with parents and staff were conducted immediately after the 10 week program for each case study group, again three months after the program, and finally, one year after the commencement of the program. Students also had the opportunity to be interviewed at the one year mark. The results of this research show that 10 weeks of specifically modified informal science activities had a beneficial impact on the student participants, varying in degree between individuals. This thesis demonstrates how science can be modified for the meaningful participation of students with mild to moderate ID. This thesis thereby contributes to the field of science communication by providing a novel means for engaging Australian students with ID, as well as opening possibilities for further interdisciplinary research between science communication and disability studies. More importantly, it demonstrates the potential for science communication as a vehicle for developing identity and agency for students with mild to moderate ID.

description: Cemeteries are globally culturally protected greenspaces in cities that meet different societal needs and often harbor high biodiversity. To harness the potential of cemeteries as urban green infrastructure, stakeholders need to understand why people visit cemeteries and their preferences. We conducted an online survey in Berlin, Germany (n = 627) to understand (i) the reasons for cemetery visits; (ii) preferences for cemetery features; (iii) the effect of a dead tree as a wilderness component on preferences for differently managed green areas (wild, meadows, lawns); (iv) preferences of nature elements as comforting experiences; and (v) how reasons for the visit and sociodemographic variables relate to respondents’ preferences. The major reasons to visit cemeteries were ‘enjoying nature’, ‘mourning’, and ‘historical interest’ and most preferred cemetery features were ‘wildlife‘, ‘solitude’, and ‘vegetation‘. Presenting a dead tree did not modulate preference ratings for green areas that were depicted on photographs. Comforting experiences with nature elements were high overall. The reasons to visit had besides socio-demographic variables predictive potential on pronounced preferences. The results underscore the importance of cemeteries as multidimensional places and indicate tolerance for the inclusion of dead trees as important wildlife habitat. Strategies to develop cemeteries as shared habitats for people and nature should also consider, besides socio-demographic background, the reasons for cemetery visits.

description: Purpose: This study aimed to determine the outcomes and impact of Dynamic Temporal and Tactile Cueing (DTTC) treatment when clear vinyl masks were worn. DTTC is one of the few evidence-based treatments for children with childhood apraxia of speech (CAS). Given that DTTC relies on visual, auditory, and tactile cues, it was unknown if treatment gains would be demonstrated when masks were worn and how masking would impact the therapy experience for clinicians and caregivers.Method: A sequential mixed methods design was used to study the efficacy of DTTC treatment in children with CAS when clear masks were worn. The quantitative phase used a multiple-baseline across-participants design. Four children (each 4 years of age) participated in the treatment protocol in which 24 sessions of DTTC were provided over 8 weeks while clear vinyl face masks were worn by participants and clinicians. Whole word accuracy on treated items and generalization to easy and hard untreated items were assessed during baseline, treatment, and follow-up. Semistructured interviews were conducted with clinicians and caregivers following treatment to explore the experience of masks being worn during treatment. Qualitative data were analyzed using descriptive thematic analysis.Results: Three children completed the treatment protocol. Visual and statistical analyses revealed that two participants demonstrated significant treatment effects, with one also demonstrating generalization. The remaining participant demonstrated marginal treatment gains. Qualitative findings revealed two main themes: “mask wearing was inconvenient but did not prevent therapy gains” and “in-person therapy with face masks was preferable to teletherapy.”Conclusions: Masks did not prohibit treatment gains during DTTC therapy, with treatment effects of varying degrees shown for the three participants who completed the protocol. Together, quantitative and qualitative results indicate that mask wearing was, for most, a minor inconvenience that did not substantially interfere with the efficacy of DTTC treatment.Supplemental Material S1.

description: Perception of the environment by sensor systems in variable environmental conditions is very complex due to the interference influences. In the field of autonomous machines or autonomous vehicles, environmental conditions play a decisive role in safe person detection. A uniform test and validation method can support the manufacturers of sensor systems during development and simultaneously provide proof of functionality. The authors have developed a concept of a novel test method, “REDA”, for this purpose. In this article, the concept is applied and measurement data are presented. The results show the versatile potential of this test method, through the manifold interpretation options of the measurement data. Using this method, the strengths and weaknesses of sensor systems have been identified with an unprecedented level of detail, flexibility, and variance to test and compare the detection capability of sensor systems. The comparison was possible regardless of the measuring principle of the sensor system used. Sensor systems have been tested and compared with each other with regard to the influence of environmental conditions themselves. The first results presented highlight the potential of the new test method. For future applications, the test method offers possibilities to test and compare manifold sensing principles, sensor system parameters, or evaluation algorithms, including, e.g., artificial intelligence.

description: The incorporation of soft hydrophilic particles at the interface of water in non-polar oil emulsion droplets is crucial for several applications. However, the stabilization of water in non-polar oil emulsions with hydrophilic soft material alone is, besides certain exceptions, not possible. In our previous works, we showed that stabilizing the emulsions with well-characterized spherical hydrophobic silica nanospheres (SNs) and soft equally charged microgel particles (MGs) is a robust strategy to stabilize w/o emulsions while still incorporating a large amount of MGs at the interface. In the present study, we address the question of what the maximum amount of MGs at the interface in these kinds of emulsion droplets can be. By using well-characterized mono-disperse SNs, we are able to calculate the fraction of interface covered by the SNs and complementary that of the present MG. We found that it is not possible to decrease the SN coverage below 56% irrespective of MG softness and SN size. The findings elucidate new perspectives to the broader topic of soft/solid stabilized emulsions.

description: Large amounts of Open Government Data (OGD) have become available and co-created public services have started to emerge, but there is only limited empirical material available on co-created OGD-driven public services. To address this shortcoming and explore the concept of co-created OGD-driven public services the authors conducted an exploratory case study. The case study explored Chicago’s use of OGD in the co-creation of a predictive analytics model that forecasts critical safety violations at food serving establishments. The results of this exploratory work allowed for new insights to be gained on co-created OGD-driven public services and led to the identification of six factors that seem to play a key role in allowing for a OGD-driven public service to be co-created. The results of the initial work also provide valuable new information that can be used to aid in the development and improvement of the authors’ conceptual model for understanding co-created OGD-driven public service.

description: Approximations to the exact density functional for the exchange-correlation energy of a many-electron ground state can be constructed by satisfying constraints that are universal, i.e., valid for all electron densities. Gedanken densities are designed for the purpose of this construction, but need not be realistic. The uniform electron gas is an old gedanken density. Here, we propose a spherical two-electron gedanken density in which the dimensionless density gradient can be an arbitrary positive constant wherever the density is non-zero. The Lieb-Oxford lower bound on the exchange energy can be satisfied within a generalized gradient approximation (GGA) by bounding its enhancement factor or simplest GGA exchange-energy density. This enhancement-factor bound is well known to be sufficient, but our gedanken density shows that it is also necessary. The conventional exact exchange-energy density satisfies no such local bound, but energy densities are not unique, and the simplest GGA exchange-energy density is not an approximation to it. We further derive a strongly and optimally tightened bound on the exchange enhancement factor of a two-electron density, which is satisfied by the local density approximation but is violated by all published GGA's or meta-GGA's. Finally, some consequences of the non-uniform density-scaling behavior for the asymptotics of the exchange enhancement factor of a GGA or meta-GGA are given.

In addition to nuclear smearing corrections that are known to be important at large values of the nucleon's parton momentum fraction x_N, we also consider dynamical off-shell nucleon corrections associated with the modifications of the bound nucleon structure inside the deuteron, which we find to be significant at intermediate and large x_N values. We also provide estimates of the nuclear corrections at kinematics corresponding to existing and planned Drell-Yan experiments at Fermilab and J-PARC which aim to determine the dbar/ubar ratio for x < 0.6.

description: To enumerate 3-manifold triangulations with a given property, one typically begins with a set of potential face pairing graphs (also known as dual 1-skeletons), and then attempts to flesh each graph out into full triangulations using an exponential-time enumeration. However, asymptotically most graphs do not result in any 3-manifold triangulation, which leads to significant "wasted time" in topological enumeration algorithms. Here we give a new algorithm to determine whether a given face pairing graph supports any 3-manifold triangulation, and show this to be fixed parameter tractable in the treewidth of the graph. We extend this result to a "meta-theorem" by defining a broad class of properties of triangulations, each with a corresponding fixed parameter tractable existence algorithm. We explicitly implement this algorithm in the most generic setting, and we identify heuristics that in practice are seen to mitigate the large constants that so often occur in parameterised complexity, highlighting the practicality of our techniques.

Compensation for large tensor modes with iso-curvature perturbations in CMB anisotropies

description: Recently, BICEP2 has reported the large tensor-to-scalar ratio $r=0.2^{+0.07}_{-0.05}$ from the observation of the cosmic microwave background (CMB) B-mode at degree-scales. Since tensor modes induce not only CMB B-mode but also the temperature fluctuations on large scales, to realize the consistent temperature fluctuations with the Planck result we should consider suppression of scalar perturbations on corresponding large scales. To realize such a suppression, we consider anti-correlated iso-curvature perturbations which could be realized in the simple curvaton model.

description: Il volume “Connessioni di diritto penale” rappresenta la tappa conclusiva di un progetto che ha preso avvio nella prima fase della pandemia da Covid-19. Proprio quando sembrava che il distanziamento potesse degenerare in isolamento, i dottorandi di diritto penale dell’Università degli Studi “Roma Tre” hanno organizzato una serie di incontri telematici per riflettere non solo sulla risposta sanzionatoria all’emergenza Coronavirus e sull’impatto della stessa in riferimento alla questione carceraria, ma anche su altre questioni centrali del dibattito penalistico più recente: le fattispecie penali introdotte in materia di reddito di cittadinanza, la natura giuridica dell’aggravante dell’agevolazione mafiosa, i nodi più problematici in materia di violenza sessuale di gruppo. I testi di quelle relazioni, riveduti, ampliati e aggiornati, sono confluiti in questo volume, in attesa che le “connessioni” si riattivino presto non solo nel mondo virtuale, ma anche nelle aule delle nostre Università.
Post-$Planck$ constraints on interacting vacuum energy

description: We present improved constraints on an interacting vacuum model using updated astronomical observations including the first data release from Planck. We consider a model with one dimensionless parameter, $α$, describing the interaction between dark matter and vacuum energy (with fixed equation of state $w=-1$). The background dynamics correspond to a generalised Chaplygin gas cosmology, but the perturbations have a zero sound speed. The tension between the value of the Hubble constant, $H_0$, determined by Planck data plus WMAP polarisation (Planck+WP) and that determined by the Hubble Space Telescope (HST) can be alleviated by energy transfer from dark matter to vacuum ($α>0$). A positive $α$ increases the allowed values of $H_0$ due to parameter degeneracy within the model using only CMB data. Combining with additional datasets of including supernova type Ia (SN Ia) and baryon acoustic oscillation (BAO), we can significantly tighten the bounds on $α$. Redshift-space distortions (RSD), which constrain the linear growth of structure, provide the tightest constraints on vacuum interaction when combined with Planck+WP, and prefer energy transfer from vacuum to dark matter ($α<0$) which suppresses the growth of structure. Using the combined datasets of Planck+WP+Union2.1+BAO+RSD, we obtain the constraint on $α$ to be $-0.0830$, but not both at the same time.

description: Cellular glutamine synthesis is thought to be an important resistance factor in protecting cells from nutrient deprivation and may also contribute to drug resistance. The application of ‟targeted stable isotope resolved metabolomics” allowed to directly measure the activity of glutamine synthetase in the cell. With the help of this method, the fate of glutamine derived nitrogen within the biochemical network of the cells was traced. The application of stable isotope labelled substrates and analyses of isotope enrichment in metabolic intermediates allows the determination of metabolic activity and flux in biological systems. In our study we used stable isotope labelled substrates of glutamine synthetase to demonstrate its role in the starvation response of cancer cells. We applied 13C labelled glutamate and 15N labelled ammonium and determined the enrichment of both isotopes in glutamine and nucleotide species. Our results show that the metabolic compensatory pathways to overcome glutamine depletion depend on the ability to synthesise glutamine via glutamine synthetase. We demonstrate that the application of dual-isotope tracing can be used to address specific reactions within the biochemical network directly. Our study highlights the potential of concurrent isotope tracing methods in medical research.

description: People drive transitions. Current urban living conditions, specifically food systems, challenge the health, wellbeing and coherence of individuals and whole societies, and for effective change toward resilient communities, people need to reinvent the way they produce, distribute and consume food. Consequently, in their communities' people are creating foodscapes and governing the transition toward sustainable local food systems. Here, we introduce a conceptual framework to develop this transformation through empowering the urban multi-stakeholder society as the agent of this process. To do so, we reviewed scientific evidence and experiences from seven selected City Regions (Albacete, Baku, Dresden, Izmir, Ljubljana, Megara, and Valparaiso) as case studies and conducted a SWOT analysis to explore the capacity of food systems to enhance multi-functionality of urban landscapes, with special focus on social cohesion and quality of life. We grasp existing policies; hone them and leverage policies and strategies toward human-centered actions for future proofing food systems.

description: In the probe limit, we study the holographic $p$-wave phase transition in the Gauss-Bonnet gravity via numerical and analytical methods. Concretely, we study the influences of the external magnetic field on the Maxwell complex vector model in the five-dimensional Gauss-Bonnet-AdS black hole and soliton backgrounds, respectively. For the two backgrounds, the results show that the magnetic field enhances the superconductor phase transition in the case of the lowest Landau level, while the increasing Gauss-Bonnet parameter always hinders the vector condensate. Moreover, the Maxwell complex vector model is a generalization of the SU(2) Yang-Mills model all the time. In addition, the analytical results backup the numerical results. Furthermore, this model might provide a holographic realization for the QCD vacuum instability.
