description: With this the special issue of Footprint the question of the relation of philosophy and architecture, and the significance of phenomenology for architectural practice and discourse is broadly surveyed. Individually, and overall, the articles provide reflections and arguments on topics of space, location, place, architectural practice, meaning in architecture, and on the impact of phenomenology as a philosophical form of enquiry throughout. Stephen Read in his paper, written out of a post-phenomenological perspective associated with the work of Don Idhe, provides the basis for a new reading of Heidegger on tools and the relation of the social and the technological. A similar concern can be seen in the paper of David Kirshner, ‘Tools: Stuff: Art’. The discourse about space emerges in architecture only towards the end of the nineteenth century, and Leslie Kavanaugh’s groundbreaking study on Brentano on space provides rich context for this turn in architectural discourse towards ‘space’. Susan Herrington and Anne Bordeleau in different ways look at the problems of constituted meanings for architecture, predominantly within the French phenomenological tradition. Michael Lazarin and Akkelies van Nes bring forward the deepening and continuing response to the work of Heidegger, through an original and new study of Norberg Schulz, and in Lazarin’s rich considerations of the contexts and sources of poetic dwelling in Japanese buildings. Randall Teal furthers the interest in the study of topology, of such concern to Hubert Dreyfus and Jeff Malpas, in the reading of the late work of Heidegger. Working as an artist and sculptor Jasper Coppes has contributed a meditative and detailed response to phenomenological ideas around place, which is of some significance for thinking about the problem of ‘domain’ in architecture. Keane and Selinger look at the work of Arakawa and Gins to demonstrate the fruitfulness of phenomenology for artistic practice and new concepts of the production of space.

description: The purpose of this pilot study was to assess the attitudes of active registered dental hygienists toward the proposed Advanced Dental Hygiene Practitioner (ADHP). Factors of support/interest in the ADHP concept, level of practice, and socio-demographics were examined. A self-administered questionnaire was mailed to 1562 active registered dental hygienists in Colorado, Kentucky, and North Carolina. Both quantitative and qualitative analyses were performed. The response rate was 29% (n = 442). Overall level of support/interest for the ADHP, indicated by cumulative totals of very and somewhat supportive/interested, was respectively 87%/74% in Colorado, 82%/71% in Kentucky, and 92%/81% in North Carolina. A significant difference was found among respondents interested in becoming an ADHP and those not interested (p<0.05). The overall level of support/interest in the proposed ADHP does not differ among the three states. A revised questionnaire and survey procedures could further improve measurement of dental hygienists' attitudes regarding the ADHP program.
Architecture and Phenomenology: Introduction

description: The implications of philosophical aesthetics in the consideration of architecture have been relatively slight. Part of the reason is the neglect of architecture in the work of Baumgarten, Burke and Kant. Within the discourse of architecture the questions raised for philosophical consideration arising out of practice restricted the area of reflection and investigation. The dominant positions were to become either a version of neo-Kantianism, or a direct re-working of Hegel’s Lectures on Aesthetics. The significance of Kant’s distinction between ‘free’ and ‘dependent beauty’ is analysed, and in consequence the need to philosophically question again the relation of architecture to buiding, to dwelling and space. For this the question of accessibility as raised in the phenomenological enquiry, in the work of Brentano, Sartre, Bachelard, Merleau-Ponty, and especially Heidegger points to a different route for the appraisal of philosophical and architectural relations which are exhibited in the contributions of the 10 authors to this issue of Footprint.

Twistronics versus straintronics in twisted bilayers of graphene and transition metal dichalcogenides

description: Several numerical studies have shown that the electronic properties of twisted bilayers of graphene (TBLG) and transition metal dichalcogenides (TMDs) are tunable by strain engineering of the stacking layers. In particular, the flatness of the low-energy moiré bands of the rigid and the relaxed TBLG was found to be, substantially, sensitive to the strain. However, to the best of our knowledge, there are no full analytical calculations of the effect of strain on such bands. We derive, based on the continuum model of moiré flat bands, the low-energy Hamiltonian of twisted homobilayers of graphene and TMDs under strain at small twist angles. We obtain the analytical expressions of the strain-renormalized Dirac velocities and explain the role of strain in the emergence of the flat bands. We discuss how strain could correct the twist angles and bring them closer to the magic angle $θ_m\sim1.05^{\circ}$ of TBLG and how it may reduce the widths of the lowest-energy bands at charge neutrality of the twisted homobilayer of TMDs. The analytical results are compared with numerical and experimental findings and also with our numerical calculations based on the continuum model.

description: In this paper, we study the estimation of partially linear models for spatial data distributed over complex domains. We use bivariate splines over triangulations to represent the nonparametric component on an irregular two-dimensional domain. The proposed method is formulated as a constrained minimization problem which does not require constructing finite elements or locally supported basis functions. Thus, it allows an easier implementation of piecewise polynomial representations of various degrees and various smoothness over an arbitrary triangulation. Moreover, the constrained minimization problem is converted into an unconstrained minimization via a QR decomposition of the smoothness constraints, which allows for the development of a fast and efficient penalized least squares algorithm to fit the model. The estimators of the parameters are proved to be asymptotically normal under some regularity conditions. The estimator of the bivariate function is consistent, and its rate of convergence is also established. The proposed method enables us to construct confidence intervals and permits inference for the parameters. The performance of the estimators is evaluated by two simulation examples and by a real data analysis.

description: We introduce a relational semantics based on poset products, and provide sufficient conditions guaranteeing its soundness and completeness for various substructural logics. We also demonstrate that our relational semantics unifies and generalizes two semantics already appearing in the literature: Aguzzoli, Bianchi, and Marra's temporal flow semantics for Hájek's basic logic, and Lewis-Smith, Oliva, and Robinson's semantics for intuitionistic Lukasiewicz logic. As a consequence of our general theory, we recover the soundness and completeness results of these prior studies in a uniform fashion, and extend them to infinitely-many other substructural logics.

description: We present linear polarization observations of the exoplanet system HD 189733 made with the HIgh Precision Polarimetric Instrument (HIPPI) on the Anglo-Australian Telescope (AAT). The observations have higher precision than any previously reported for this object. They do not show the large amplitude polarization variations reported by Berdyugina et al. 2008 and Berdyugina et al. 2011. Our results are consistent with polarization data presented by Wiktorowicz et al. 2015. A formal least squares fit of a Rayleigh-Lambert model yields a polarization amplitude of 29.4 +/- 15.6 parts-per-million. We observe a background constant level of polarization of ~ 55-70 ppm, which is a little higher than expected for interstellar polarization at the distance of HD 189733.

description: Body-worn camera and citizen device videos capturing police use-of-force are shared and commented upon widely within social media. This study investigated how point-of-view (POV: onlooker vs. officer perspective) and citizen skin color (dark skin vs. light skin), interacted to affect emotional responses, likelihood to comment and share, and comment on content. A predominantly White sample watched police use-of-force videos in which citizen skin color and camera POV varied. Body-worn camera (BWC) videos in which light-skinned citizens were harmed elicited the most likelihood to comment and share. Further, experienced negative emotion fully mediated this relationship. BWC videos in which dark-skinned citizens were harmed elicited the least negative emotion, the least likelihood to comment, and less normative commentary about officer behaviors.

description: For massless vertex-transitive transient graphs, the percolation phase transition for the level sets of the Gaussian free field on the associated continuous cable system is particularly well understood, and in particular the associated critical parameter $\widetilde{h}_*$ is always equal to zero. On general transient graphs, two weak conditions on the graph $\mathcal{G}$ are given in arXiv:2101.05800, each of which implies one of the two inequalities $\widetilde{h}_*\leq0$ and $\widetilde{h}_*\geq0.$ In this article, we give two counterexamples to show that none of these two conditions are necessary, prove that the strict inequality $\widetilde{h}_*<0$ is typical on massive graphs with bounded weights, and provide an example of a graph on which $\widetilde{h}_*=\infty.$ On the way, we obtain another characterization of random interlacements on massive graphs, as well as an isomorphism between the Gaussian free field and the Doob $\mathit{\mathbf{h}}$-transform of random interlacements, and between the two-dimensional pinned free field and random interlacements.

Mapping Urban Complexity in an Asian Context

Publisher: name: FOOTPRINT
Year: 2008

description: The second issue of Footprint aims at reuniting two themes which are receiving a great deal of attention in recent times: Asia’s extraordinary urban growth, and the problematique of mapping highly complex urban environments. The 21st century, forecasted by many as the ‘Pacific Century’, brings to the fore the region's economic, social, political and cultural changes, wide-ranging in their manifestation and far-reaching in their consequence. All of these factors are inscribed in the urban environment. In a region where a population of one million constitutes a small settlement and mega-cities such as Tokyo and Shanghai have come to dominate the global network, sheer size is itself an important issue and not just in practical terms. Then there is the apparent chaos that is actually a delicately balanced autopoeisis in cities such as Mumbai, as well as the interesting and potentially useful city-state model of Hong Kong. These conditions and rising phenomena bring important questions on the potentials and relevance of mapping to the fore.

description: Future wireless networks need to offer orders of magnitude more capacity to address the predicted growth in mobile traffic demand. Operators to enhance the capacity of cellular networks are increasingly using WiFi to offload traffic from their core networks. This paper deals with the efficient and flexible management of a heterogeneous networking environment offering wireless access to multimode terminals. This wireless access is evaluated under disruptive usage scenarios, such as flash crowds, which can mean unwanted severe congestion on a specific operator network whilst the remaining available capacity from other access technologies is not being used. To address these issues, we propose a scalable network assisted distributed solution that is administered by centralized policies, and an embedded reputation system, by which initially selfish operators are encouraged to cooperate under the threat of churn. Our solution after detecting a congested technology, including within its wired backhaul, automatically offloads and balances the flows amongst the access resources from all the existing technologies, following some quality metrics. Our results show that the smart integration of access networks can yield an additional wireless quality for mobile flows up to thirty eight percent beyond that feasible from the best effort standalone operation of each wireless access technology. It is also evidenced that backhaul constraints are conveniently reflected on the way the flow access to wireless media is granted. Finally, we have analyzed the sensitivity of the handover decision algorithm running in each terminal agent to consecutive flash crowds, as well as its centralized feature that controls the connection quality offered by a heterogeneous access infrastructure owned by distinct operators.

description: Participants read English-based online texts from fictional organizations that either included no code-mixing, Hawaiian words without glosses (i.e., parenthetical translations), or Hawaiian words with English glosses. Relative to no code-mixing, code-mixing without glosses disrupted processing fluency, leading participants to feel less welcome in the organization. Code-mixing with glosses did not disrupt fluency for participants from Hawai‘i, where this practice is common, but did for people from elsewhere. No differences in feeling welcome emerged between code-mixing with glosses and no code-mixing conditions. These results suggest that code-mixing in written organizational materials can have both costs (i.e., disrupted fluency) and benefits (i.e., cueing inclusiveness), and that these effects depend on audiences’ familiarity with code-mixing as a practice, and the format of code-mixing.

description: Die Dissertation untersucht die Entwicklung des Gesamtkunstwerk-Konzeptes und seine Aktualität, Möglichkeit und Notwendigkeit in Bezug auf ein modernes filmisches Gesamtkunstwerk. Ausgegangen wird von der ästhetischen Theorie und Praxis der deutschen Frühromantik, in der das Konzept wurzelt. In einer umfassenden Betrachtung und Analyse der ästhetischen und gesellschaftspolitischen Dimension des Konzeptes in den Schriften und dem Werk Richard Wagners sollen wesentliche Strukturmerkmale erkundet und soll ein Maßstab für ein ‚positives‘ zeit-genössisches Gesamtkunstwerk gebildet werden, das sich von seinem ideologischen Missbrauch befreit. Erforscht wird, inwiefern der Farb- und Tonspielfilm ein geeignetes Kunstmedium für die Anwendung des Konzeptes darstellt und wie sich die Frage seiner gesellschaftspolitischen Dimension in der globalen Epoche übersetzen lässt.
description: The dissertation explores the evolution of the concept of the Total Work of Art (ʹGesamtkunstwerkʹ) as well as its actuality, feasibility and necessity in the form of a modern cinematic Gesamtkunstwerk. Starting point is the aesthetic theory and praxis of the Early German Romanticism, in which the concept is rooted. An extensive consideration and analysis of the concept in both its aesthetic and socio-political dimension as developed in the writings and works of Richard Wagner aims to define its essential structural features and to set the standard for a ʹpositiveʹ contemporary Gesamtkunstwerk beyond its ideological abuse. Key is the examination of how and to what extend the sound and colour feature film constitutes a legit artistic medium for the application of the concept as well as how its sociopolitical facet translates within the global era.
Ephemeral China/Handmade China
Creators: name: Ruan, Xing
Publisher: name: FOOTPRINT
Year: 2008

description: A China that is in a frenzied state of economic boom and potential social instability, which is most vividly represented in its architectural and urban developments, is, I hope I will convince you, ephemeral. A quite different China, perhaps is not so visible as its new buildings and cities, is metaphorically ‘handmade’. I should like to extend the meanings of the handmade to the more stable and long lasting attitudes towards social life, and even mortality. My sources for the second China are partially from literature (not from architecture). With the construction boom since the mid-1990s, mainstream Western architectural journals and galleries have been racing to expose new architecture in China; celebrity Western architects have been winning major commissions in China: the 2008 Beijing Olympic Games is a case in point. The sheer quantity and speed of China’s development, as evidenced in architecture and urbanisation, causes an ‘unbearable lightness of being’ (to paraphrase Milan Kundera). Does all this then suggest that China, as solidified in its buildings and cities, is no longer ‘handmade’ in the sense that memory and a sense of history are redundant (particularly for a country that has a recorded history of more than 5000 years, which have been so lovingly recorded in handmade artefacts)? The true meaning of the handmade, which absorbs labour — an ‘honourable labour’ as Joseph Conrad lovingly put it in his Mirror of the Sea, as well as memory, like that of a home, is a static artefact, which harbours our changing emotion, the frailties of human life, and indeed, the growing awareness that comes with time of our mortality: the handmade offers the necessary enshrinement of life’s vulnerability. Let me assure you, the seemingly fast-changing China, as represented in its new architecture and city forms, as well in its frenzied urbanisation and booming economy, is but a smoke screen. It is, in other words, ephemeral. The other China is, or has to be, handmade.

description: Stochastic Optimal Control (SOC) typically considers noise only in the process model, i.e. unknown disturbances. However, in many robotic applications involving interaction with the environment, such as locomotion and manipulation, uncertainty also comes from lack of precise knowledge of the world, which is not an actual disturbance. We analyze the effects of also considering noise in the measurement model, by developing a SOC algorithm based on risk-sensitive control, that includes the dynamics of an observer in such a way that the control law explicitly depends on the current measurement uncertainty. In simulation results on a simple 2D manipulator, we have observed that measurement uncertainty leads to low impedance behaviors, a result in contrast with the effects of process noise that creates stiff behaviors. This suggests that taking into account measurement uncertainty could be a potentially very interesting way to approach problems involving uncertain contact interactions.

description: We present a study of spatial variations in the metallicity of old red giant branch stars in the Andromeda galaxy. Photometric metallicity estimates are derived by interpolating isochrones for over seven million stars in the Panchromatic Hubble Andromeda Treasury (PHAT) survey. This is the first systematic study of stellar metallicities over the inner 20 kpc of Andromeda's galactic disk. We see a clear metallicity gradient of $-0.020\pm0.004$ dex/kpc from $\sim4-20$ kpc assuming a constant RGB age. This metallicity gradient is derived after correcting for the effects of photometric bias and completeness and dust extinction and is quite insensitive to these effects. The unknown age gradient in M31's disk creates the dominant systematic uncertainty in our derived metallicity gradient. However, spectroscopic analyses of galaxies similar to M31 show that they typically have small age gradients that make this systematic error comparable to the 1$σ$ error on our metallicity gradient measurement. In addition to the metallicity gradient, we observe an asymmetric local enhancement in metallicity at radii of 3-6 kpc that appears to be associated with Andromeda's elongated bar. This same region also appears to have an enhanced stellar density and velocity dispersion.

description: The aim of this article is to study semigroups of composition operators on the BMOA-type spaces $BMOA_p$, and on their "little oh" analogues $VMOA_p$. The spaces $BMOA_p$ were introduced by R. Zhao as part of the large family of F(p,q,s) spaces, and are the Möbius invariant subspaces of the Dirichlet spaces $D^p_{p-1}$. We study the maximal subspace of strong continuity, providing a sufficient condition on the infinitesimal generator of $ϕ$, under which $[ϕ_t,BMOA_p]=VMOA_p$, and a related necessary condition in the case where the Denjoy - Wolff point of the semigroup is in $\mathbb{D}$. Further, we characterize those semigroups, for which $[ϕ_t, BMOA_p]=VMOA_p$, in terms of the resolvent operator of the infinitesimal generator of $T_t$. In addition we provide a connection between the maximal subspace of strong continuity and the Volterra-type operators $T_g$. We characterize the symbols g for which $T_g$ acting from $BMOA$ to $BMOA_1$ is bounded or compact, thus extending a related result to the case $p=1$. We also prove that for $1

description: Automated story generation is the problem of automatically selecting a sequence of events, actions, or words that can be told as a story. We seek to develop a system that can generate stories by learning everything it needs to know from textual story corpora. To date, recurrent neural networks that learn language models at character, word, or sentence levels have had little success generating coherent stories. We explore the question of event representations that provide a mid-level of abstraction between words and sentences in order to retain the semantic information of the original data while minimizing event sparsity. We present a technique for preprocessing textual story data into event sequences. We then present a technique for automated story generation whereby we decompose the problem into the generation of successive events (event2event) and the generation of natural language sentences from events (event2sentence). We give empirical results comparing different event representations and their effects on event successor generation and the translation of events to natural language.

description: The Zeemal Heaton Lake metasedimentary assemblage comprises ~50% of the eastern limb of the North Caribou greenstone belt, which hosts the Musselwhite gold deposit (~ 5.4 Moz Au). The metasedimentary assemblage is divided into two based on their distribution: the Central-belt and North-rim of the belt. The Zeemal Heaton Lake metasedimentary rocks have been interpreted to represent a turbidite succession, consisting of pelite, arkose, wacke and conglomerate. Detrital U-Pb zircon age populations from this study indicate variable sources in the Central-belt metasediments with a maximum age of deposition of 2798.8 ± 29 Ma, while metasediments along the North portion of the limb display a maximum age of deposition of 2696 ± 39 Ma. This indicates the likelihood of two discrete basins with the Zeemal Heaton Lake assemblage. Neodymium isotopic values for the sedimentary rocks along the North-rim of the belt display εNd2680Ma ranging from -1.2 to -0.9. An overlapping but slightly more evolved signature shown in the Central portion with values of εNd2800Ma -1.6 to 0.1. This indicates detritus for the Central-belt was likely sourced from the older (~2850 Ma), (tonalite-granodiorite) surrounding intrusions. The North-rim sediments were sourced (in part) from the younger (~2700 Ma) granitic intrusions and rhyolites. The surrounding batholiths display εNdt overlapping with North-rim sedimentary rocks, however, indicate significant contribution beyond these immediate surrounding batholiths, which may include older mafic (2982 ± 0.8, 2870 ±2 Ma), younger rhyolitic unit (2723 ± 2 Ma) or more distal sources than the intrusions immediately adjacent to the belt. Peak metamorphic mineral assemblages indicate a minimum of amphibolite facies-garnet zone or greater across the Central-belt portion of the greenstone belt. The North-rim metasediments display evidence for aureole metamorphism which may overprint earlier regional metamorphism. Nitrogen abundance and δ15N values of biotite of the Zeemal Heaton Lake metasedimentary assemblage indicate variable values than those associated with mineralization at the Musselwhite Mine, which is reported by Isaacs (2008). Mineralizing fluids from the Musselwhite mine have been interpreted by Issacs (2008) to be related to both metamorphic and magmatic fluids. Fluids associated with the Eyapamikama and/or Zeemal Heaton Lake metasediments appear to be metamorphic with minor magmatic influence near regional shear zones, but not directly related to the auriferous fluids which formed the Musselwhite mine.

description: In light of the recent Muon $g-2$ experiment data from Fermilab, we investigate the implications of a gauged $L_μ - L_τ$ model for high energy neutrino telescopes. It has been suggested that a new gauge boson at the MeV scale can both account for the Muon $g-2$ data and alleviate the tension in the Hubble parameter measurements. It also strikes signals at IceCube from the predicted resonance scattering between high-energy neutrinos and the cosmic neutrino background. We revisit this model based on the latest IceCube shower data, and perform a four-parameter fit to find a preferred region. We do not find evidence for secret interactions. The best-fit points of $m_{Z'}$ and $g_{μτ}$ are $\sim10$~MeV and $\sim0.1$, respectively, depending on assumptions regarding the absolute neutrino masses, and the secret interaction parameter space allowed by the observed IceCube data overlaps with the regions of the parameter space that can explain the muon $g-2$ anomaly and Hubble tension as well. We demonstrate that future neutrino telescopes such as IceCube-Gen2 can probe this unique parameter space, and point out that successful measurements would infer the neutrino mass with $0.06~{\rm eV}\lesssim Σm_ν\lesssim 0.3~{\rm eV}$.

We investigated the locally delivered effects of ketorolac tromethamine (KT), a potent nonsteroidal anti-inflammatory drug (NSAID), on orthodontic tooth movements in twelve Wistar rats. U-shaped expansion springs were positioned between upper first molars exerting equal and reciprocal, laterally directed forces for seventeen days. Every fourth day 1.5 mg of KT in solution was delivered around one molar and saline solution was injected adjacent to the contralateral molar. Subsequent to a wash-out period lasting fifteen days of continued expansion, the appliances were removed, the teeth allowed to relapse for thirteen days while the same schedule was maintained for the NSAID delivery. Combining the data from all the teeth that received KT and comparing those with the control data, no significant differences were seen with their movements during the expansion or relapse phases.

description: The Kepler Mission has detected dozens of compact planetary systems with more than four transiting planets. This sample provides a collection of close-packed planetary systems with relatively little spread in the inclination angles of the inferred orbits. A large fraction of the observational sample contains limited multiplicity, begging the question whether there is a true diversity of multi transiting systems, or if some systems merely possess high mutual inclinations, allowing them to appear as single-transiting systems in a transit-based survey. This paper begins an exploration of the effectiveness of dynamical mechanisms in exciting orbital inclination within exoplanetary systems of this class. For these tightly packed systems, we determine that the orbital inclination angles are not spread out appreciably through self-excitation. In contrast, the two Kepler multi-planet systems with additional non-transiting planets are susceptible to oscillations of their inclination angles, which means their currently observed configurations could be due to planet-planet interactions alone. We also provide constraints and predictions for the expected transit duration variations (TDVs) for each planet. In these multi-planet compact Kepler systems, oscillations of their inclination angles are remarkably hard to excite; as a result, they tend to remain continually mutually transiting (CMT-stable). We study this issue further by augmenting the planet masses and determining the enhancement factor required for oscillations to move the systems out of transit. The oscillations of inclination found here inform the recently suggested dichotomy in the sample of solar systems observed by Kepler.

description: IoT devices are increasingly being implicated in cyber-attacks, driving community concern about the risks they pose to critical infrastructure, corporations, and citizens. In order to reduce this risk, the IETF is pushing IoT vendors to develop formal specifications of the intended purpose of their IoT devices, in the form of a Manufacturer Usage Description (MUD), so that their network behavior in any operating environment can be locked down and verified rigorously. This paper aims to assist IoT manufacturers in developing and verifying MUD profiles, while also helping adopters of these devices to ensure they are compatible with their organizational policies. Our first contribution is to develop a tool that takes the traffic trace of an arbitrary IoT device as input and automatically generates a MUD profile for it. We contribute our tool as open source, apply it to 28 consumer IoT devices, and highlight insights and challenges encountered in the process. Our second contribution is to apply a formal semantic framework that not only validates a given MUD profile for consistency, but also checks its compatibility with a given organizational policy. Finally, we apply our framework to representative organizations and selected devices, to demonstrate how MUD can reduce the effort needed for IoT acceptance testing.

description: Legionaminic acid (Leg5,7Ac2) is a nonulosonic acid similar to sialic acid (Neu5Ac), which can be found in the extracellular glycoconjugates of several bacterial pathogens. Due to the similarity in stereochemistry of the two compounds, legionaminic acid has great potential in the production of pharmaceutical drugs. A novel biosynthetic pathway to produce legionaminic acid was created to overcome the limitations of organic synthesis. This is the first study involving the scale-up of legionaminic acid production by high cell density fermentation processes. In this work, fed-batch cultivations of recombinant Escherichia coli BRL04 were carried out in shake flasks and 5-L bioreactors. The final process was optimized by determining the effects of different carbon sources, induction temperatures, pH, dissolved oxygen (DO) content, induction optical density and N-acetylglucosamine (GlcNAc) feed rate on the production of legionaminic acid. Overall, results showed that the titer, yield and productivity for legionaminic acid production achieved relatively high levels, which were 5.53 g/L, 73.29% and 0.092 g/(Lh), respectively. It is hoped that this study accelerates research into the production of legionaminic acid for therapeutic treatments as well as for further study in glycobiology.

description: This research studies the impact of online news on social and economic consumer perceptions through semantic network analysis. Using over 1.8 million online articles on Italian media covering four years, we calculate the semantic importance of specific economic-related keywords to see if words appearing in the articles could anticipate consumers' judgments about the economic situation and the Consumer Confidence Index. We use an innovative approach to analyze big textual data, combining methods and tools of text mining and social network analysis. Results show a strong predictive power for the judgments about the current households and national situation. Our indicator offers a complementary approach to estimating consumer confidence, lessening the limitations of traditional survey-based methods.

description: Language-modeling--based approaches to story plot generation attempt to construct a plot by sampling from a language model (LM) to predict the next character, word, or sentence to add to the story. LM techniques lack the ability to receive guidance from the user to achieve a specific goal, resulting in stories that don't have a clear sense of progression and lack coherence. We present a reward-shaping technique that analyzes a story corpus and produces intermediate rewards that are backpropagated into a pre-trained LM in order to guide the model towards a given goal. Automated evaluations show our technique can create a model that generates story plots which consistently achieve a specified goal. Human-subject studies show that the generated stories have more plausible event ordering than baseline plot generation techniques.

description: We consider the mean curvature flow of a closed hypersurface in the complex or quaternionic projective space. Under a suitable pinching assumption on the initial data, we prove apriori estimates on the principal curvatures which imply that the asymptotic profile near a singularity is either strictly convex or cylindrical. This result generalizes to a large class of symmetric ambient spaces the estimates obtained in the previous works on the mean curvature flow of hypersurfaces in Euclidean space and in the sphere.

description: We consider the optimization problem corresponding to the sharp constant in a conformally invariant Sobolev inequality on the $n$-sphere involving an operator of order $2s> n$. In this case the Sobolev exponent is negative. Our results extend existing ones to noninteger values of $s$ and settle the question of validity of a corresponding inequality in all dimensions $n\geq 2$.
