description: Microalgae are unicellular or simple multicellular photosynthetic microorganisms of rapid growth rate and high photosynthesis efficiency. They have been established as efficient cellular photoreactors with diverse applications in biomanufacturing and environment engineering. However, high algal farming costs have so far impeded large-scale growth of algal biomass and cell density culture (HCDC) of microalgae has shown great potential in reducing algal farming costs. This thesis presents an in-depth study on the HCDC of microalgae using a novel horizontal thin-layer algal reactor with green alga Neochloris oleoabundans as the model species. Systematic analyses on the effects of culture medium composition including nitrogen (N) and dissolved inorganic carbon (DIC) concentration as well as cultivation conditions, e.g., culture pH, light intensity, culture thickness, and intermittent mixing, were conducted. Biomass concentration of up to 35 g/L and areal productivities of up to 16.32 g/m²/day were achieved. About 98% savings in stirring energy was achieved by adopting a 10-min on and 2-hour off intermittent mixing strategy while obtaining algal growth kinetics similar to that of continuous mixing. It was demonstrated that an incident light intensity of 750 μmol photons/m²/s and DIC of 80 mM or above were inhibitive to cell division while promoting enlargement of individual cells. A simple equation was proposed and validated to correlate the extinction coefficient with the biomass concentration, allowing more accurate modelling of the light attenuation of algal culture using the Beer-Lambert equation. It was also demonstrated that, when the experimental kinetic data were generated using the correctly, the Monod equation, which has been widely applied to modelling the growth kinetics of heterotrophic microorganism, could be used to model the photoautotrophic growth of microalgae with satisfactory accuracy, resolving a long-standing challenge in this field. It was also demonstrated that the conversion factor in the spectrometric determination of biomass concentration, which has been wide applied to suspended cultures of microbial, plant, and animal cells, was dependent on cell size and cell composition and should therefore be experimentally determined carefully.

description: The IIP-Ecosphere platform is a central asset developed by the IIP-Ecosphere project. The core aim of the platform is to research and demonstrate novel platform concepts for Industry 4.0, e.g., asset administration shells as interfaces for software components and resources, unified edge deployment, an AI toolkit or seamless configuration of a platform from network settings via services up to applications running on the platform. This platform handbook provides insights into the rationales, ideas and concepts that make up the design and the realization of the IIP-Ecosphere platform, ranging from an overall layered architecture over a detailed discussion of the design and realization state of each layer up to cross-cutting mechanisms such as the configuration model or the related code/artifact generation. This platform handbook addresses the technical side of the platform work in IIP-Ecosphere and builds on the intensive prior work on requirements (usage view and functional/quality requirements of the platform). This handbook shall provide means for deeper technical discussions with partners, stakeholders and interested parties, but also allow for a technical understanding to contribute to the platform, e.g., in terms of protocols, platform connectors, services or demonstration applications. This artifact contains version 0.2.0 in accordance to the release version on Github. We will update this document with the next release of the IIP-Ecosphere platform.

description: Scattering of sub-GeV dark matter (DM) particles with hydrogen atoms is studied in this paper. The interactions of DM with electrons and nucleons are both included and formulated in a general framework based on nonrelativistic effective field theory. On the assumption of same dark matter coupling strengths, it is found that DM-electron interactions dominate the inelastic atomic transitions to discrete excited states and ionization continuum around the threshold regions, and DM-nucleon interactions become more important with increasing energy and dominate in elastic scattering. The conclusion should apply, qualitatively, to practical detector species so that electronic and nuclear contributions in DM scattering processes can be disentangled, while issues including binding effects and recoil mechanism in many-body systems will require further detailed calculations.

description: This study investigated longitudinal associations between adolescents’ technology-based communication and the development of interpersonal competencies within romantic relationships. A school-based sample of 487 adolescents (58% girls; Mage = 14.1) participated at two time points, one year apart. Participants reported (1) proportions of daily communication with romantic partners via traditional modes (in person, on the phone) versus technological modes (text messaging, social networking sites) and (2) competence in the romantic relationship skill domains of negative assertion and conflict management. Results of cross-lagged panel models indicated that adolescents who engaged in greater proportions of technology-based communication with romantic partners reported lower levels of interpersonal competencies one year later, but not vice versa; associations were particularly strong for boys.
Towards Cognitively Plausible Associative Memories Capable of Learning Complex Tasks

Year: 2024
Subjects: Artificial Neural Networks

Cognition

description: This thesis explores the development of artificial neural networks (ANNs) grounded in cognitive principles. Specifically, it focuses on Associative Memories (AMs) and how to improve their learning properties while retaining cognitive plausibility. To do so, gradual architectural and functioning changes are explored, ultimately leading to a framework for multilayered and multinetwork AMs capable of learning complex tasks while sharing the same underlying principle. Chapter 1 investigates the variability and consistency within an unsupervised AM in categorizing similar and distinct stimuli, demonstrating that while individual representations vary, the learning outcomes are consistent across networks. Chapter 2 combines unsupervised AMs to create a multilayered architecture capable of learning and gradually distinguishing highly correlated inputs. Chapter 3 integrates this unsupervised architecture into a Bidirectional Associative Memory (BAM) to form a multilayered BAM capable of learning non-linear tasks relying solely on local associative learning processes. Chapter 4 presents a novel binary transmission function for AMs that improves biological plausibility while maintaining high learning performance. It also investigates the new properties gained by binary encoding, such as information flow control and memory replay, which facilitate dynamic interactions between multiple networks. The thesis concludes by discussing the implications of these findings for artificial intelligence and cognitive modelling and suggests future research directions for developing more robust and adaptable neural network architectures. It emphasizes the growing importance of multidisciplinary collaboration across various perspectives and fields in unravelling the complexities of brain function.

description: A hierarchical multiscale approach to model the magnetization dynamics of ferromagnetic ran- dom alloys is presented. First-principles calculations of the Heisenberg exchange integrals are linked to atomistic spin models based upon the stochastic Landau-Lifshitz-Gilbert (LLG) equation to calculate temperature-dependent parameters (e.g., effective exchange interactions, damping param- eters). These parameters are subsequently used in the Landau-Lifshitz-Bloch (LLB) model for multi-sublattice magnets to calculate numerically and analytically the ultrafast demagnetization times. The developed multiscale method is applied here to FeNi (permalloy) as well as to copper- doped FeNi alloys. We find that after an ultrafast heat pulse the Ni sublattice demagnetizes faster than the Fe sublattice for the here-studied FeNi-based alloys.

description: In this thesis, we study graphene's optical and electrical properties, primarily focusing on bilayer graphene (BLG) quantum dots (QDs). We discuss a tight-binding model to accurately model the single-particle behavior of monolayer and bilayer graphene. Additionally, we introduce theoretical and numerical methods, including the many-body Hamiltonian, configuration interaction method, Bethe-Salpeter equation (BSE), and computation of Coulomb matrix elements to analyze electron-electron interactions in many-body systems. We examine gated BLG under a perpendicular electric field, which opens a gap in the band structure. Next, lateral gates can be applied in a way that leads to the emergence of a QD that effectively confines electrons and holes. Employing an atomistic tight-binding model for millions of atoms, we compute the single-particle QD energy spectrum and dipole matrix elements (DMEs) to analyze the oscillator strengths and optical selection rules. We incorporate electron-electron interactions via microscopic Coulomb matrix elements and solve the BSE to obtain the excitonic energy spectrum. Furthermore, we obtain the excitonic absorption spectrum and predict the existence of dark low-energy exciton states. Subsequently, we examine the effects of a shallow lateral confining potential and trigonal warping (TW) on the electronic structure of laterally gated BLG QDs. We begin by analyzing the influence of TW on the QD energy spectrum as the confining potential depth varies. We find a regime where the QD levels are dominated by the presence of three minivalleys for each K-valley. We obtain the absorption spectrum for a shallow confining potential depth, which further amplifies the effects of TW on the optical properties. Our results predict two degenerate bright exciton states, each built of the three minivalley states. Finally, we utilize an effective mass model for BLG QDs to explain the previously observed optical selection rules, where TW effects were neglected. Labeling the QD states with a generalized angular momentum gives deeper insights into the selection rules that were not apparent in the atomistic model. Understanding interacting electrons and holes in gated BLG QDs opens potential applications in storing, detecting, and manipulating photons in the terahertz (THz) energy range.

description: In de voorgaande hoofdstukken werd ingegaan op de context en het theoretisch kader. Hierna volgt het empirische deel van het onderzoek met allereerst een verkennende casestudy in voorliggend hoofdstuk, gestructureerd op basis van het IAD framework van Ostrom (2011) zoals toegelicht in hoofdstuk 3. Deze enkelvoudige casestudy is uitgevoerd om grip te krijgen op beïnvloedende factoren bij investeringsbeslissingen in stedelijke vernieuwing. De resultaten en inzichten die volgen uit de casestudy vormen de basis voor het ontwerp van de gamesimulaties, die aan bod komen in de hoofdstukken 5, 6 en 7. In dit hoofdstuk wordt de casus Vernieuwingsplan Centrumgebied Kanaleneiland in Utrecht behandeld. Het betreft een stedelijke gebiedsontwikkeling met als hoofdstrategie sloop/nieuwbouw, aansluitend op de focus van dit onderzoek. Het gebied omvatte aan het begin van de vernieuwing significant corporatiebezit van twee woningcorporaties, gecombineerd met commerciële en maatschappelijke functies. Het gelijkwaardige bezit en positie van de woningcorporaties Portaal en Mitros in het gebied als vertrekpunt, maakt vergelijkende analyse en onderzoek naar wederzijdse beïnvloeding mogelijk. De vernieuwing wordt gekenmerkt door een complexe samenwerkingsvorm met publieke en private actoren en een lange looptijd, waarbinnen veel contextuele veranderingen hebben plaatsgevonden waaronder de economische crisis in 2008. De interacties tussen de actoren lijken veel invloed te hebben gehad op de investeringsbeslissingen en uitkomsten van de vernieuwing. De casestudy is uitgevoerd op basis van interviews met de betrokken actoren, ondersteund door inhoudsanalyse en studie van besluitdocumenten, overeenkomsten en het complete projectdossier dat beschikbaar was vanuit woningcorporatie Portaal. De geanalyseerde documenten zijn niet opgenomen in dit proefschrift, maar wel beschikbaar via de auteur. De casestudy heeft plaatsgevonden in het laatste kwartaal van 2015. Begin 2019 heeft een laatste update van de informatie plaatsgevonden in overleg met de actoren. In de volgende paragraaf wordt de opzet van de casestudy uiteengezet. Paragraaf 4.3 geeft een beschrijving van de casus in Kanaleneiland Centrum, de investeringsopgave en de samenwerkingsvorm. In paragraaf 4.4 worden de resultaten van de interviews behandeld. In paragraaf 4.5 worden de resultaten bediscussieerd en geabstraheerd naar een algemeen niveau, waarna deze in paragraaf 4.6 worden vertaald in aannames ten behoeve van de gamesimulaties. De conclusies zijn weergegeven in paragraaf 4.7.

description: Phylogenetic trees are a central tool in understanding evolution. They are typically inferred from sequence data, and capture evolutionary relationships through time. It is essential to be able to compare trees from different data sources (e.g. several genes from the same organisms) and different inference methods. We propose a new metric for robust, quantitative comparison of rooted, labeled trees. It enables clear visualizations of tree space, gives meaningful comparisons between trees, and can detect distinct islands of tree topologies in posterior distributions of trees. This makes it possible to select well-supported summary trees. We demonstrate our approach on Dengue fever phylogenies.

description: Volume limitations and low yield thresholds of biological fluids have led to widespread use of passive microparticle rheology. The mean-squared-displacement (MSD) statistics of bead position time series (bead paths) are either applied directly to determine the creep compliance [Xu et al (1998)] or transformed to determine dynamic storage and loss moduli [Mason & Weitz (1995)]. A prevalent hurdle arises when there is a non-diffusive experimental drift in the data. Commensurate with the magnitude of drift relative to diffusive mobility, quantified by a P\'eclet number, the MSD statistics are distorted, and thus the path data must be "corrected" for drift. The standard approach is to estimate and subtract the drift from particle paths, and then calculate MSD statistics. We present an alternative, parametric approach using maximum likelihood estimation that simultaneously fits drift and diffusive model parameters from the path data; the MSD statistics (and consequently the compliance and dynamic moduli) then follow directly from the best-fit model. We illustrate and compare both methods on simulated path data over a range of P\'eclet numbers, where exact answers are known. We choose fractional Brownian motion as the numerical model because it affords tunable, sub-diffusive MSD statistics consistent with typical 30 second long, experimental observations of microbeads in several biological fluids. Finally, we apply and compare both methods on data from human bronchial epithelial cell culture mucus.

description: We report ab-initio calculations for the electronic structure of organic charge transfer salts $κ$-(ET)$_2$Cu[N(CN)$_2$]Br, $κ$-(ET)$_2$Cu[N(CN)$_2$]I, $κ^{\prime \prime}$-(ET)$_2$Cu[N(CN)$_2$]Cl and $κ$-(ET)$_2$Cu$_2$(CN)$_3$. These materials show an ordering of the relative orientation of terminal ethylene groups in the BEDT-TTF molecules at finite temperature and our calculations correctly predict the experimentally observed ground state molecular conformations (eclipsed or staggered). Further, it was recently demonstrated that the ethylene endgroup relative orientations can be used to reversibly tune $κ$-(ET)$_2$Cu[N(CN)$_2$]Br through a metal-insulator transition. Using a tight-binding analysis, we show that the molecular conformations of ethylene endgroups are intimately connected to the electronic structure and significantly influence hopping and Hubbard repulsion parameters. Our results place $κ$-(ET)$_2$Cu[N(CN)$_2$]Br in eclipsed and staggered configurations on opposite sides of the metal-insulator transition.

description: The detection of unmodeled gravitational-wave bursts by ground-based interferometric gravitational-wave detectors is a major goal for the advanced detector era. These searches are commonly cast as pattern recognition problems, where the goal is to identify statistically significant clusters in spectrograms of strain power when the precise signal morphology is unknown. In previous work, we have introduced a clustering algorithm referred to as "seedless clustering," and shown that it is a powerful tool for detecting weak long-lived (10-1000s) signals in background. However, as the algorithm is currently conceived, in order to carry out an all-sky search on a $\approx$ year of data, significant computational resources may be required in order to carry out background estimation. Alternatively, some of the sensitivity of the search must be sacrificed to control computational costs. The sensitivity of the algorithm is limited by the amount of computing resources due to the requirement of performing background studies to assign significance in gravitational-wave searches. In this paper, we present an analytic method for estimating the background generated by the seedless clustering algorithm and compare the performance to both Monte Carlo Gaussian noise and time-shifted gravitational-wave data from a week of LIGO's 5th Science Run. We demonstrate qualitative agreement between the model and measured distributions and argue that the approximation will be useful to supplement conventional background estimation techniques for advanced detector searches for long-duration gravitational-wave transients.

description: Because of DNA appealing features as perfect material, including minuscule size, defined structural repeat and rigidity, programmable DNA-mediated processing is a promising computing paradigm, which employs DNAs as information storing and processing substrates to tackle the computational problems. The massive parallelism of DNA hybridization exhibits transcendent potential to improve multitasking capabilities and yield a tremendous speed-up over the conventional electronic processors with stepwise signal cascade. As an example of multitasking capability, we present an in vitro programmable DNA-mediated optimal route planning processor as a functional unit embedded in contemporary navigation systems. The novel programmable DNA-mediated processor has several advantages over the existing silicon-mediated methods, such as conducting massive data storage and simultaneous processing via much fewer materials than conventional silicon devices.

description: Aircraft fuel tanks contain baffle structures with openings or orifices through which fluid can flow. For CFD simulations, fine computational mesh resolutions are often required within the orifices to resolve the flow through these openings with sufficient accuracy for engineering. This work presents a method of replacing the fine computational mesh elements within the openings or orifices with large one-dimensional orifice elements that integrates seamlessly with standard finite volume computational elements with the intended advantage of reducing the overall computational cost. These one-dimensional elements conserve mass and momentum for two-phase flow in incompressible Volume-Of-Fluid CFD. Instead of resolving the momentum diffusion term, they use empirical correlations to account for the losses within the orifices within an accelerating reference frame for both two- and three-dimensional simulations. The one-dimensional orifice elements are developed and validated against analytical and experimental results using the finite volume CFD code Elemental®. Furthermore, these elements are tested in a violent sloshing simulation and compared to full resolution numerical results as well as experimental results. The elements are shown to decrease computational cost by reducing the number of computational elements as well as increasing the simulation time step sizes (due an increase in element sizes)

description: The purpose of this study was to evaluate two practical interval training protocols on cardiorespiratory fitness, lipids, and body composition in overweight/obese women. Thirty women (mean ± SD; Weight: 88.1 ± 15.9 kg; BMI: 32.0 ± 6.0 kg·m2) were randomly assigned to ten 1-minute high-intensity intervals (90%VO2peak, 1min recovery), or five 2-minute high-intensity intervals (80-100% VO2peak, 1 min recovery), or control. Peak oxygen uptake (VO2peak), peak power output, body composition, and fasting blood lipids were evaluated before and after 3 weeks of training, completed 3 days per week. Results from ANCOVA analyses demonstrated no significant training group differences for any primary variables (p>0.05). When training groups were collapsed, 1MIN and 2MIN resulted in a significant increase in peak power output (∆18.9 ± 8.5 watts; p=0.014) and time to exhaustion (∆55.1 ± 16.4 sec; p=0.001); non-significant increase in VO2peak (∆2.36 ± 1.34 ml·kg−1·min−1; p=0.185); and a significant decrease in fat mass (∆−1.96 ± 0.99kg; p=0.011). Short-term interval exercise training may be effective for decreasing fat mass and improving exercise tolerance in overweight and obese women.

description: We change the framing of classical DA (a la VL Smith, JPE, 1962) trading experiments from the usual buyer-seller frame to an employer-employee frame. Roberto Weber from UZH conjectured during a seminar at UZH in 2022 that this might neutralize or reverse the asymmetry of convergence that we previously found (see Ikica et al., 2023, IER).

description: ABSTRACTCombining dynamic postural control assessments and cognitive tasks may give clinicians a more accurate indication of postural control under sport-like conditions compared to single-task assessments. We examined postural control, cognitive and squatting performance of healthy individuals during static and dynamic postural control assessments in single- and dual-task paradigms. Thirty participants (female = 22, male = 8; age = 20.8 ± 1.6 years, height = 157.9 ± 13.0 cm, mass = 67.8 ± 20.6 kg) completed single-leg stance and single-leg squat assessments on a force plate individually (single-task) and concurrently (dual-task) with two cognitive assessments, a modified Stroop test and the Brooks Spatial Memory Test. Outcomes included centre of pressure speed, 95% confidence ellipse, squat depth and speed and cognitive test measures (percentage of correct answers and reaction time). Postural control performance varied between postural control assessments and testing paradigms. Participants did not squat...

description: We propose a cost-effective outcome-dependent sampling design for the failure time data and develop an efficient inference procedure for data collected with this design. To account for the biased sampling scheme, we derive estimators from a weighted partial likelihood estimating equation. The proposed estimators for regression parameters are shown to be consistent and asymptotically normally distributed. A criteria that can be used to optimally implement the ODS design in practice is proposed and studied. The small sample performance of the proposed method is evaluated by simulation studies. The proposed design and inference procedure is shown to be statistically more powerful than existing alternative designs with the same sample sizes. We illustrate the proposed method with an existing real data from the Cancer Incidence and Mortality of Uranium Miners Study.

Laxoplumeria aberrans

description: Laxoplumeria aberrans J.F.Morales, sp. nov. (Figs. 1, 6)
 Type: — FRENCH GUIANA. Saul: La Fumée Mountain Trail, Saül, from carbet to base of steep and mean hill, 16 Sep 1989, Mori, Gracie, Angell, Rothman & Lifton-Schwerner 20933 (Holotype, NY!; isotypes, CR!, P!).
 Laxoplumeria aberrans is recognized by its petioles 10–16 mm long, leaf blade ovate to ovate-elliptic, corolla tube 4–6 × 1.5–2.1 mm, corolla lobes 15–17 mm long, and nectary surrounding the ovary.
 Trees or shrubs, possible lianas; stems glabrous, with milky sap. Leaves alternate, petioles 10–16 mm; leaf blade (8.5–)11–16 × (4–) 4.5–6.4 cm, obovate to elliptic-obovate, the apex acute to obtuse-apiculate, the base narrowly cuneate, glabrous, with 13–16 pairs of secondary veins. Inflorescences 9–14 cm long, glabrous, peduncles 38–90 mm, pedicels 6–10 mm, bracts up to 0.6 mm; calyx lobes 0.7–0.9 mm, ovate, the apex obtuse to acute, glabrous; corolla greenish yellow, glabrous, tube 4–6 × 1.5–2.1 mm, lobes 15–17 × 1.6–1.8 mm, narrowly elliptic to narrowly ovate-elliptic; stamens inserted in the proximal part of the corolla tube, near the base, anthers 1.7–1.8 mm; ovary 1–1.2 mm, nectary 1.7–1.9 mm, surrounding completely the ovary. Follicles 30–42 × 0.4–0.8 cm, glabrous; seeds 2.8–3 cm, coma 0.4–1.6 cm, tan.
 Distribution and habitat: — Endemic to French Guiana, growing in tropical non-flooded moist forest, at 200– 400 m. Flowering in February, April, and September. Fruiting in September and December.
 Observations:— Laxoplumeria aberrans resembles L. baehniana and L. tessmannii but it is distinguished by its petioles 10–16 mm long (vs. 10–38 mm), pedicels 6–10 mm long (vs. 1.5–3 mm), and corolla lobes 15–17 mm (vs. 6–7.5 mm long). Three different habits are reported for this species: liana (Mori et al. 20933), shrub (Cremers 8149), and tree (Tostain et al. 1769). Additional fieldwork needs to be done to corroborate if the “liana” habit is real or just a misinterpretation of the collector. In addition, the nectary covers completely the ovary, a feature previously not reported in Laxoplumeria. Although these irregular characters, the fruits and seeds are characteristic of the genus.
 Paratypes: FRENCH GUIANA. Saúl: Route de Saint Laurent a Paul Isnard, entre le PK 70 y Citron au PK 118, Cremers 8149 (P); La Fumée Oeste, Mori & Pipoly 15537 (CR, NY, P); Fleuve Maroni, Pompidou-Papaichton, Sastre 6491 (P); aval Crique Roche, Tostain et al. 1769 (P).
