description: ACM factor responsible for myofibroblast induction is both heat labile and lipid associated. ACM was heat inactivated (ACM HI) or lipid depleted (ACM LD) and then applied to fibroblasts. To see if two different factors, one heat labile and one lipid associated were responsible, the HI and LD medias were combined in a 1:1 ratio and applied to fibroblasts (ACM HI+LD). Myofibroblast conversion measured via fluorescent immunolabeling of -SMA. Data is mean ± SD, N=3. One-way ANOVA conducted with Dunnett's multiple comparisons test. *p>0.05.

description: In the standard model of particle physics, all fermions are fundamentally massless and only acquire their effective bare mass when the Higgs field condenses. Therefore, in a fundamental de Broglie-Bohm pilot-wave quantum field theory (valid before and after the Higgs condensation), position beables should be attributed to massless fermions. In our endeavour to build a pilot-wave theory of massless fermions, which would be relevant for the study of quantum non-equilibrium in the early universe, we are naturally led to Weyl spinors and to particle trajectories which give meaning to the `zig-zag' picture of the electron discussed recently by Penrose. We show that a positive-energy massive Dirac electron of given helicity can be thought of as a superposition of positive and negative energy Weyl particles of the same helicity and that a single massive Dirac electron can in principle move luminally at all times. This is however not true for the many body situation required by quantum field theory and we conclude that a more natural theory arises from attributing beable status to the positions of massless Dirac particles instead of to Weyl particles.

description: The Casimir interaction is omnipresent source of forces at small separations between bodies, which is difficult to change by varying external conditions. Here we show that graphene interacting with a metal can have the best known force contrast to the temperature and the Fermi level variations. In the distance range 50-300 nm the force is measurable and can vary a few times for graphene with a bandgap much larger than the temperature. In this distance range the main part of the force is due to the thermal fluctuations. We discuss also graphene on a dielectric membrane as a technologically robust configuration.

description: We investigate if there is a difference in the lithium abundances of stars belonging to two halo populations of F and G main-sequence stars previously found to differ in [alpha/Fe] for the metallicity range -1.4 < [Fe/H] < -0.7. Li abundances are derived from the LiI 6707.8 A line measured in high-resolution spectra using MARCS model atmospheres. Furthermore, masses of the stars are determined from the logTeff - logg diagram by interpolating between Yonsei-Yale evolutionary tracks. There is no significant systematic difference in the lithium abundances of high- and low-alpha halo stars. For the large majority of stars with masses 0.7 < M/M_sun < 0.9 and heavy-element mass fractions 0.001 < Z < 0.006, the Li abundance is well fitted by a relation A(Li) = a0 + a1 M + a2 Z + a3 M Z, where a0, a1, a2, and a3 are constants. Extrapolating this relation to Z = 0 leads to a Li abundance close to the primordial value predicted from standard Big Bang nucleosynthesis calculations and the WMAP baryon density. The relation, however, does not apply to stars with [Fe/H] < -1.5. We suggest that metal-rich halo stars were formed with a Li abundance close to the primordial value, and that lithium in their atmospheres has been depleted in time with an approximately linear dependence on stellar mass and Z. The lack of a systematic difference in the Li abundances of high- and low-alpha stars indicates that an environmental effect is not important for the destruction of lithium.

description: The effect of antimony substitution for niobium on potassium sodium niobate (KNN) ceramic was investigated with respect to the densification behaviour at different sintering temperatures, microstructure and electrical properties. Sb5+ was slightly added while simultaneously lowering the amount of Nb5+and in this study of the (K0.5Na0.5)(Nb1-xSbx)O3 system, x content was varied from 0 to 14 mol.% Our results show that Sb5+ slightly increased the optimum sintering temperature for KNN but above 8 mol %, its resistivity and piezoelectric properties decreased. As the amount of Sb5+ substituted is increased, the structure of the ceramic transformed from orthorhombic to pseudocubic which led to slight shrinkage in the unit cell volume. Microstructural examination revealed that above 10 mol %, a second phase (K2NaSb3O9) was formed which segregated mainly to the grain boundary while the quantitative EDX analysis showed that there was A-site vacancy due to loss of the alkali elements. The two phase transitions points, Curie temperature (TC) and the tetragonal to orthorhombic (TT-O) shifted to lower temperature with increasing Sb5+ content and above 10 mol %, the TT-O shifted to below room temperature. The dielectric loss slightly increases with increasing Sb5+ content up to 200°C. There was an improvement in the piezoelectric properties with ≤ 6 mol % Sb content while optimum properties were obtained with 4 mol % (KP = 0.46, Qm= 6.2, NP = 2296).
OBJECT EXPLORATION, CHARACTERIZATION, AND RECOGNITION BASED ON TACTILE SENSING
Creators: name: Xiao, Chenxi
Publisher: name: Purdue University Graduate School

Subjects: Industrial engineering

description: Tactile sensing is an essential human ability for understanding their surroundings. It allows humans to detect and manipulate objects that are concealed or difficult to see in low-light settings. Further, tactile sensing enables people to comprehend object and surface properties that cannot be obtained through visual feedback alone. This is achieved with gentle touches, enabling tactile exploration of fragile, sensitive objects, or living organisms. This capability could be transferred to robots through suitable hardware and algorithms. Nevertheless, current tactile sensors and skills for robotics are not comparable to the tactile sense of humans, thus resulting in inferior characterization of scenes and a risk of altering object states.
 To address these limitations, this dissertation proposes a novel framework for robot active tactile exploration and object characterization. The framework combines bioinspired soft sensors and minimally invasive tactile exploration strategies to minimize perturbations to objects. This framework was achieved by: (1) an ultrasensitive whisker sensor that enables object characterization with minimal interaction forces; (2) autonomous tactile exploration skills to localize objects and then characterize their shape and surface properties; and (3) machine learning techniques to analyze contact information gathered by our tactile sensors, enabling the understanding of object attributes by tactile sensing alone.
 Experiments were conducted to validate the effectiveness of the framework. In terms of object localization efficiency, informative path planners and contour exploration patterns outperformed baseline methods. Furthermore, the whisker sensor was successfully employed to characterize object surface and liquid properties. Finally, the features found through the characterization process allowed for successful classification by machine learning techniques. These results indicate that the proposed framework can effectively gather multimodal features from environments while maintaining the safety of objects.
A study of high proper-motion white dwarfs I. Spectropolarimetry of a cool hydrogen-rich sample

description: We conducted a spectropolarimetic survey of 58 high proper-motion white dwarfs which achieved uncertainties of >2 kG in the Halpha line and >5 kG in the upper Balmer line series. The survey aimed at detecting low magnetic fields (< 100 kG) and helped identify the new magnetic white dwarfs NLTT 2219, with a longitudinal field B_l = -97 kG, and NLTT 10480 (B_l=-212 kG). Also, we report the possible identification of a very low-field white dwarf with B_l = -4.6 kG. The observations show that ~5% of white dwarfs harbour low fields (~10 to ~10^2 kG) and that increased survey sensitivity may help uncover several new magnetic white dwarfs with fields below ~1 kG. A series of observations of the high field white dwarf NLTT 12758 revealed changes in polarity occurring within an hour possibly associated to an inclined, fast rotating dipole. Also, the relative strength of the pi and sigma components in NLTT 12758 possibly revealed the effect of a field concentration ("spot"), or, most likely, the presence of a non-magnetic white dwarf companion. Similar observations of NLTT 13015 also showed possible polarity variations, but without a clear indication of the timescale. The survey data also proved useful in constraining the chemical composition, age and kinematics of a sample of cool white dwarfs as well as in constraining the incidence of double degenerates.

description: The ever-evolving digitisation of research across all disciplines yearns for an equally evolving offer of corresponding services. Diverse and large collections of research data become useful for researchers especially when they are FAIR. Comprehensive, user-friendly, and accurate search interfaces are important elements within this context. The DARIAH-DE Data Federation Architecture (DFA) responds to these requirements with its services. As a well-established integral part of DARIAH-DE, the DFA is now also intertwined with the CLARIN search spaces; most notably the Federated Content Search has become an endpoint for the DARIAH-DE Collection Registry. This integration work is pursued by the BMBF-funded project CLARIAH-DE and aims at research institutions and individual researchers alike.

Influence of Application Placement, Resistance Genotype, and PPO-Inhibiting Herbicide on the PPO-Resistance Phenotype in Waterhemp
Creators: name: Haarmann, Jesse A
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Agrochemicals and biocides (incl. application)

description: PPO inhibitors are a valuable group of herbicides that provide soil-residual and foliar control of glyphosate resistant Amaranthus species. The ΔG210 mutation in the PPX2 gene confers PPO-inhibitor resistance and has been present in the Midwest for more than a decade. Until recently, PPO-inhibitor resistance in waterhemp was attributable to just the ΔG210 mutation in the PPX2 gene, but recently, several new PPO-resistant biotypes have been discovered in waterhemp and Palmer amaranth. A possible explanation is a change in PPO-inhibitor use patterns and commonly used active ingredients. A direct comparison of the ΔG210 mutation and a new mutation, R128G, was conducted in the greenhouse. Results indicate that the R128G mutation in waterhemp is not substantially better than the ΔG210 mutation with respect to conferring resistance to PPO inhibitors applied preemergence. Furthermore, there is no evidence that the utility of PPO inhibitors applied preemergence will diminish any further as a result of the R128G mutation increasing in frequency. A set of field trials was conducted to investigate how a new PPO inhibitor, trifludimoxazin, will select for resistant biotypes in the field. Overall, a greater number of resistant plants survived the foliar herbicide applications than emerged through soil applications. Trifludimoxazin did not increase the frequency of PPO-resistant individuals when applied to soil, but when applied to foliage, increased the frequency of PPO-resistant individuals by 2.5 to 2.6-fold, similar to other PPO inhibitors applied to foliage. In other experiments, investigations of waterhemp populations with unique resistance phenotypes were conducted. In populations that were more resistant than others, yet had the same ΔG210 mutation, there was no evidence of herbicide metabolism contributing to the greater resistance phenotype. In resistant populations that had no target site mutations, target site expression experiments and lipid peroxidation experiments were inconclusive. However, there was some evidence of increased target-site expression or increased antioxidant capacity as being causal mechanisms, although no mechanisms have been fully ruled out.

description: The homemade, low-cost Young flat-plate solar collector, well suited for multiple agricultural uses, was designed by a Nebraska farm couple and personnel from the Small Farm Energy Project. It is portable and tillable, with a flexible airflow system. The collector satisfactorily dried grain and heated the Young farm home. Use of the collector in the fall and winter of 1979 saved 331 gallons of propane worth $179. Net energy savings yielded an 11.2-percent return on investment and, including allowable tax credits, gave a payback of 5.8 years, making this collector--with an expected 20-year life--an attractive investment for farmers and lending institutions.
Spin-phonon coupling induced frustration in the exactly solved spin-1/2 Ising model on a decorated planar lattice

description: The spin-1/2 Ising model with a spin-phonon coupling on decorated planar lattices partially amenable to lattice vibrations is examined within the framework of the generalized decoration-iteration transformation and the harmonic approximation. It is shown that the magnetoelastic coupling gives rise to an effective antiferromagnetic next-nearest-neighbour interaction, which competes with the nearest-neighbour interaction and is responsible for a frustration of the decorating spins. The strong enough spin-phonon coupling consequently leads to an appearance of the striking partially ordered and partially disordered phase, where a perfect antiferromagnetic alignment of the nodal spins is accompanied with a complete disorder of the decorating spins. The diversity in temperature dependences of the total specific heat is investigated in connection with the particular behaviour of its magnetic and lattice contribution.

description: Bipartite entanglement between two parties of a composite quantum system can be quantified in terms of the purity of one party and there always exists a pure state of the total system that maximizes it (and minimizes purity). When many different bipartitions are considered, the requirement that purity be minimal for all bipartitions gives rise to the phenomenon of entanglement frustration. This feature, observed in quantum systems with both discrete and continuous variables, can be studied by means of a suitable cost function whose minimizers are the maximally multipartite-entangled states (MMES). In this paper we extend the analysis of multipartite entanglement frustration of Gaussian states in multimode bosonic systems. We derive bounds on the frustration, under the constraint of finite mean energy, in the low and high energy limit.

EPFL 50th Anniversary

description: One way to grasp EPFL is to draw it. This visualization illustrates the institution’s history by using 8,000 theses that have been defended over fifty years. An automatic textual analysis was run over all of them to extract the terms that describe each specific work with respect to the whole collection, which is maintained by the EPFL Library. The theses were then placed in a circular space, that recalls a cell-culture dish. Their position depends on a lexical measure that designs a space based on similarities. The closer that two theses are, the stronger their scientific terminology is. This arrangement unfolds over time, making visible the development of scientific production. Currently, EPFL publishes more than one thesis a day, which means that at least one scholar a day is introduced into the scientific community. By looking at the visualization, it is possible to understand the interdisciplinary connections that exist despite the division of disciplines in science. As bacteriologists use a Petri dish to study cell culture, likewise visitors are invited to observe the academic evolution of EPFL in an interactive visual instrument.

description: Nowadays, magnetoresponsive soft materials, based not simply on magnetic nanoparticles, but rather on multiple components with distinct sizes and magnetic properties, both in liquid and polymeric carriers, are becoming more and more wide-spread due to their unique and versatile macroscopic response to an applied magnetic field. The variability of the latter is related to a complex interplay of the magnetic interactions in a highly non-uniform internal fields caused by spatial inhomogeneity in multicomponent systems. In this work, we present a combine analytical and simulation study of binary superparamagnetic systems, containing nanoclusters and dispersed single-domain nanoparticles, both in liquid and solid carrier matrices. We investigate the equilibrium magnetic response of these systems in wide ranges of concentrations and interaction energies. It turns out that, while the magnetisation of a binary solid can be both above and below that of an ideal superparamagnetic gas, depending on the concentration of the dispersed phase and the interparticle interactions, the system in a liquid carrier is highly magnetically responsive. In liquid, a spatial redistribution of the initially homogeneously dispersed phase in the vicinity of the nanocluster is observed -- the effect that is reminiscent of the so-called ``haloing'' effect previously observed experimentally on micro- and milli-scales.

description: Quantum systems unfold diversified correlations which have no classical counterparts. These quantum correlations have various different facets. Quantum entanglement, as the most well known measure of quantum correlations, plays essential roles in quantum information processing. However, it has recently been pointed out that quantum entanglement cannot describe all the nonclassicality in the correlations. Thus the study of quantum correlations in separable states attracts widely attentions. Herein, we experimentally investigate the quantum correlations of separable thermal states in terms of quantum discord. The sudden change of quantum discord is observed, which captures ambiguously the critical point associated with the behavior of Hamiltonian. Our results display the potential applications of quantum correlations in studying the fundamental properties of quantum system, such as quantum criticality of non-zero temperature.

description: Der aktuelle Forschungsstand zu Schwangerschaft und Flucht zeigt eine Leerstelle hinsichtlich der wissenschaftlichen Analyse der Versorgungssituation schwangerer geflüchteter Frauen*, insbesondere in Verbindung mit der Erforschung der Unterbringungssituation. Die vorliegende Masterarbeit schließt an diese Leerstelle an und untersucht die Versorgung schwangerer geflüchteter Frauen*, die in Unterkünften für Asylsuchende in Berlin leben. Darüber hinaus fragt die Arbeit nach Ungleichheiten in den Versorgungsstrukturen, mit denen schwangere geflüchtete Frauen* konfrontiert sind sowie nach Verbesserungsansätzen, um diesen zu begegnen. Um die Forschungsfragen zu beantworten, wurden sechs teilstrukturierte, leitfadenbasierte Expert*inneninterviews mit drei Hebammen und drei Sozialarbeiterinnen, die in Unterkünften für Asylsuchende in Berlin arbeiten, geführt. Diese wurden mittels der qualitativen Inhaltsanalyse nach Mayring (2015) ausgewertet. Die Ergebnisse zeigen, dass die Lebenssituation in einer Unterkunft mit Gemeinschaftsbädern und -küchen oder Vollversorgung während einer Schwangerschaft mit verschiedenen Belastungen einhergehen kann. Das Leben in einer Unterkunft - und somit auch die Schwangerschaft - ist geprägt von fehlender Selbstbestimmung. Die Betreuung der Frauen* in den Unterkünften durch das Hebammenprogramm des Landesamts für Flüchtlingsangelegenheiten Berlin (LAF) entspricht nicht der 1:1 Versorgung durch eine private Hebamme. Sichtbar werden Ungleichheiten anhand diverser Zugangsbarrieren zum Versorgungssystem, wie Rassismen und Diskriminierungen oder der Sprachbarriere, die der vollumfänglichen Inanspruchnahme reproduktiver Rechte für geflüchtete Frauen* entgegenstehen.

description: In addition to its search for extra-solar planets, the NASA Kepler Mission provides exquisite data on stellar oscillations. We report the detections of oscillations in 500 solartype stars in the Kepler field of view, an ensemble that is large enough to allow statistical studies of intrinsic stellar properties (such as mass, radius and age) and to test theories of stellar evolution. We find that the distribution of observed masses of these stars shows intriguing differences to predictions from models of synthetic stellar populations in the Galaxy.

Valproic acid : mechanisms of hepatotoxicity and reaction phenotyping
Creators: name: Kiang, Tony (Kuo-Liang)
Publisher: name: University of British Columbia
Year: 2009

description: Valproic acid (VPA) therapy is associated with a rare but severe hepatotoxicity. The relationships between the various pathophysiological findings of VPA-induced hepatotoxicity and the role of VPA biotransformation in the induction of hepatotoxicity have not been systematically investigated. The present thesis compared the effects of VPA, synthesized VPA metabolites, and alpha-F-VPA on markers of mitochondrial dysfunction (WST-1), cytotoxicity (LDH), oxidative stress (DCF), and glutathione (GSH) depletion in a novel model of sandwich-cultured rat hepatocytes (SCRH). The contribution of the CYP- and UGT-mediated biotransformation of VPA in VPA-induced toxicity was also examined. Time-dependent effects of VPA on GSH depletion were characterized in relation to the effects of VPA on the WST-1, LDH, and DCF markers. The effects of glutathione supplementation on the attenuation of the markers for VPA-induced toxicities were investigated. Urine samples from children on VPA therapy were assayed to correlate levels of VPA metabolites with the lipid peroxidation marker, 15-F2t-isoprostane. Lastly, the contributions of hepatic CYP-enzymes in the oxidative metabolism of VPA were characterized in human liver microsomes. Our findings in SCRH indicated that (E)-2,4-diene-VPA was the only exogenously administered metabolite tested that was consistently more toxic than VPA. Consistent with this finding, alpha-F-VPA, which is resistant to bioactivation by several biotransformation pathways, was nontoxic. Chemical inhibition experiments indicated that the CYP- and UGT-mediated metabolism of VPA or the in situ generated VPA metabolites were unlikely involved in the observed VPA-induced toxicities in SCRH. Furthermore, VPA-associated GSH depletion appeared not to be a factor in the mitochondrial dysfunction, but may play a partial role in VPA-induced cytotoxicity. GSH may serve a protective role against VPA-induced oxidative stress in SCRH. In human subjects, the VPA-glucuronide or N-acetylcysteine metabolites were extremely weak but statistically significant predictors of lipid peroxidation in the urine of children receiving VPA. From the reaction phenotyping experiments, CYP2C9 was the major catalyst for the formation of 4-ene-VPA, 4-OH-VPA, and 5-OH-VPA in human liver microsomes, whereas CYP2A6 contributed partially to 3-OH-VPA formation. Overall, these findings add significant knowledge to the role of VPA and its metabolites in the induction of hepatotoxicity and how VPA is metabolized in humans.

description: Excerpt from the report Summary: In summary, we recommend that the AMS fruit and vegetable market news program report contract prices and terms to complement reporting of fresh market prices which are widely available for most fruits and vegetables. The marketing system has changed since the institution of the Federal-State market news reporting system with its heavy emphasis on fresh market commodities. It is time to move ahead with expanded coverage of the processing segment of the market, which is now larger than the fresh market segment for major fruits and vegetables.

description: This panel presents new primary research results in the formal study of poetry and poetics that have been made possible by the development and use of innovative digital technologies. The research questions underlying the presentations are varied, as are the linguistic and cultural traditions (early modern and modern Russian; medieval Spanish; and Urdu [in comparison with Hindi/Sanskrit and Persian/Arabic]). What unites the three presentations is 1) a focus on using digital technologies to create humanities knowledge that would not otherwise be possible; 2) the development of innovative methodologies that are able to address those research questions; and 3) the building of new digital tools that make it possible to address new research needs.

description: Automated program repair (APR) aims to automatize the process of repairing software bugs in order to reduce the cost of maintaining software programs. Moreover, the success (given by the accuracy metric) of APR approaches has increased in recent years. However, no previous work has considered the energy impact of repairing bugs automatically using APR. The field of green software research aims to measure the energy consumption required to develop, maintain, and use software products. This paper combines, for the first time, the APR and Green software research fields. We have as main goal to define the foundation for measuring the energy consumption of the APR activity. We measure the energy consumption of ten traditional program repair tools for Java and ten fine-tuned Large-Language Models (LLM) on source code trying to repair real bugs from Defects4J, a set of real buggy programs. The initial results from this experiment show the existing trade-off between energy consumption and the ability to correctly repair bugs: Some APR tools are capable of achieving higher accuracy by spending less energy than other tools.
Angular processes related to Cauchy random walks

Subjects: subject: Probability (math.PR)

description: We study the angular process related to random walks in the Euclidean and in the non-Euclidean space where steps are Cauchy distributed. This leads to different types of non-linear transformations of Cauchy random variables which preserve the Cauchy density. We give the explicit form of these distributions for all combinations of the scale and the location parameters. Continued fractions involving Cauchy random variables are analyzed. It is shown that the $n$-stage random variables are still Cauchy distributed with parameters related to Fibonacci numbers. This permits us to show the convergence in distribution of the sequence to the golden ratio.

description: Vertical Federated Learning (VFL) is a federated learning setting where multiple parties with different features about the same set of users jointly train machine learning models without exposing their raw data or model parameters. Motivated by the rapid growth in VFL research and real-world applications, we provide a comprehensive review of the concept and algorithms of VFL, as well as current advances and challenges in various aspects, including effectiveness, efficiency, and privacy. We provide an exhaustive categorization for VFL settings and privacy-preserving protocols and comprehensively analyze the privacy attacks and defense strategies for each protocol. In the end, we propose a unified framework, termed VFLow, which considers the VFL problem under communication, computation, privacy, as well as effectiveness and fairness constraints. Finally, we review the most recent advances in industrial applications, highlighting open challenges and future directions for VFL.

A High Spatial Resolution Study of the λ=3 mm Continuum of Orion-KL

description: Recent interferometric observations have called into question the traditional view of the Orion-KL region, which displays one of the most well-defined cases of chemical differentiation in a star-forming region. Previous, lower-resolution images of Orion-KL show emission signatures for oxygen-bearing organic molecules toward the Orion Compact Ridge, and emission for nitrogen-bearing organic molecules toward the Orion Hot Core. However, more recent observations at higher spatial resolution indicate that the bulk of the molecular emission is arising from many smaller, compact clumps that are spatially distinct from the traditional Hot Core and Compact Ridge sources. It is this type of observational information that is critical for guiding astrochemical models, as the spatial distribution of molecules and their relation to energetic sources will govern the chemical mechanisms at play in star-forming regions. We have conducted millimeter imaging studies of Orion-KL with various beam sizes using CARMA in order to investigate the continuum structure. These λ;=3mm observations have synthesized beam sizes of ~0.5"-5.0". These observations reveal the complex continuum structure of this region, which stands in sharp contrast to the previous structural models assumed for Orion-KL based on lower spatial resolution images. The new results indicate that the spatial scaling previously used in determination of molecular abundances for this region are in need of complete revision. Here we present the results of the continuum observations, discuss the sizes and structures of the detected sources, and suggest an observational strategy for determining the proper spatial scaling to accurately determine molecular abundances in the Orion-KL region.
