description: We analyze the effect of external financing and associated bankruptcy threat on the speed of product innovation in a market characterized by technological and demand uncertainty. In a dynamic market setting we characterize the optimal R&D investment strategy of a monopolistic incumbent firm that can invest to develop a new product with uncertain demand. The size of the R&D investment flow determines the distribution of the stochastic innovation time and at the same time influences the dynamic evolution of firm’s liquidity. If liquidity is negative the firm faces bankruptcy risk. We show that the optimal investment is a U-shaped function of liquidity and characterize under which circumstances it is optimal for the firm to go into debt in order to speed up innovation. Furthermore, we show that, due to the existence of financial frictions, the relationship between the incumbent’s profit on the existing market and the expected innovation time for the new product is non-monotone and follows a titled-z shape. We empirically verify the theoretically derived prediction of a U-shaped relationship between liquidity and investment using a dataset consisting of a sample of 400.000 Italian manufacturing companies.

description: Polarization resolved micro-Raman spectroscopy was carried out at the edges of bilayer graphene. We find strong dependence of the intensity of the G band on the incident laser polarization, with its intensity dependence being 90 degrees out of phase for the armchair and zigzag case, in accordance with theoretical predictions. For the case of mixed-state edges we demonstrate that the polarization contrast reflects the fractional composition of armchair and zigzag edges, providing a monitor of edge purity, which is an important parameter for the development of efficient nanoelectronic devices.

description: In the recent paper of Hooper & Goodenough (1010.2752) it was reported that gamma-ray emission from the Galactic Center region contains an excess compared to the contributions from the large-scale diffuse emission and known point sources. This excess was argued to be consistent with a signal from annihilation of Dark Matter with a power law density profile. We reanalyze the Fermi data and find instead that it is consistent with the "standard model" of diffuse emission and of known point sources. The main reason for the discrepancy with the interpretation of 1010.2752 is different (as compared to the previous works) spectrum of the point source at the Galactic Center assumed in 1010.2752. We discuss possible reasons for such an interpretation.

description: Following a demonstration of how neutron diffraction with polarization analysis may be applied for the accurate determination of the coherent static structure factor of disordered materials containing substantial amounts of proton nuclei (Temleitner et al., Phys. Rev. B 92, 014201, 2015), we now focus on the incoherent scattering. Incoherent contributions are responsible for the great difficulties while processing standard (non-polarized) neutron diffraction data from hydrogenous materials, hence the importance of the issue. Here we report incoherent scattering intensities for liquid acetone, cyclohexane, methanol and water, as function of the $^1$H/H ratio. The incoherent intensities are determined directly by polarized neutron diffraction. This way, possible variations of the incoherent background due to the changing chemical environment may be monitored. In addition, for some of the water samples, incoherent intensities as a function of the wavelength of the incident neutron beam (at 0.4, 0.5 and 0.8 Å) have also been measured. It is found that in each case, the incoherent intensity can be described by a single Gaussian function, within statistical errors. The (full) width (at half maximum) of the Gaussians clearly depends on the applied wavelength. On the other hand, the different bonding environments of hydrogen atoms do not seem to affect the width of the Gaussian.

description: In this paper we present a method to obtain Banach spaces of universal and almost-universal disposition with respect to a given class $\mathfrak M$ of normed spaces. The method produces, among other, the Gurari\uı space $\mathcal G$ (the only separable Banach space of almost-universal disposition with respect to the class $\mathfrak F$ of finite dimensional spaces), or the Kubis space $\mathcal K$ (under {\sf CH}, the only Banach space with the density character the continuum which is of universal disposition with respect to the class $\mathfrak S$ of separable spaces). We moreover show that $\mathcal K$ is not isomorphic to a subspace of any $C(K)$-space -- which provides a partial answer to the injective space problem-- and that --under {\sf CH}-- it is isomorphic to an ultrapower of the Gurari\uı space. We study further properties of spaces of universal disposition: separable injectivity, partially automorphic character and uniqueness properties.

Conditions apply : non-state actors challenging state sovereignty through Intergovernmental Organizations : an analysis of national liberation movements and indigenous peoples at the United Nations
Creators: name: Lüdert, Jan
Publisher: name: University of British Columbia
Year: 2016

description: This dissertation contributes to the study of Intergovernmental Organizations (IGOs), such as the United Nations, and demonstrates their important function to convene multiple actors engaged in normative contestation and change. It achieves this by offering a systematic theoretical and empirical account of how non-state actors (NSAs) challenge the institution of state sovereignty. The argument offered specifically seeks to answer how and under what conditions this challenge is possible, and whether and when states respond by limiting IGOs and/or NSAs. To answer this question, the dissertation analyzes the successes and failures of two sets of non-state actors that have sought to alter prevailing conceptions of state sovereignty: national liberation movements and indigenous peoples. The dissertation’s original contributions to existing knowledge are threefold. First, I build on existing constructivist theory to argue that state sovereignty is despite being resilient and hard to change, also a mutable and variable composite institution. I specify that state sovereignty’s variance finds its clearest expression in three international norms that makes up the institution: territoriality, non-interference and self-determination. Second, I develop and apply the significance of three explanatory factors of non-state actors using IGOs to challenge and change the composite parts of state sovereignty: a) non-state actors require meaningful access and must expand participation capabilities to relevant venues within the nested structure of the IGO; b) non-state actors rely on the often essential role of allies active in the IGO to influence venue constraints and outcomes; c) non-state actors and their allies must find, create and/or be able to change relevant venues in order to advance collective goals through persuasion and social pressure tactics. I identify a particularly critical venue type which is coined sheltered venue. Sheltered venues establish a foot in the door to the IGO through which non-state actors deepen their interaction with states. Finally, I offer a detailed empirical investigation of national liberation movements and indigenous peoples interacting with the UN. No study of these actors in comparison exists to date. I, as such, explore how decisions and outcomes that benefited national liberation movements impacted indigenous peoples’ engagement at the United Nations.

description: Large farms are controlling a significantly larger share of farm sales and land. Large farms have acquired more resources and captured the higher sales primarily because they quickly responded to price changes by altering the mix of land use and by using land rental arrangements instead of buying or selling property. This report examines changes in the distribution of land, sales, and tenure among farms. Changes are put into a consistent perspective by adjusting farm sales classes to correct for the substantial inflation during 1969-82.

Joan La Barbara's early explorations of the voice
Creators: name: Ripley, Samara
Publisher: name: University of British Columbia
Year: 2016

description: Experimental composer and performer Joan La Barbara treats the voice as a musical instrument. Through improvisation, she has developed an array of signature sounds, or extended vocal techniques, that extend the voice beyond traditional conceptions of Western classical singing. At times, her signature sounds are primal and unfamiliar, drawing upon extreme vocal registers and multiple simultaneous pitches. In 2003, La Barbara released Voice is the Original Instrument, a two-part album that comprises a selection of her earliest works from 1974 – 1980. The compositions on this album reveal La Barbara’s experimental approach to using the voice. Voice Piece: One-Note Internal Resonance Investigation explores the timbral palette within a single pitch. Circular Song plays with the necessity of a singer’s breath by vocalizing, and therefore removing, all audible inhalations and exhalations. Hear What I Feel brings the sense of touch into an improvisatory composition and performance experience. In October Music: Star Showers and Extraterrestrials, La Barbara moves past experimentation and layers her different sounds into a cohesive piece of music. This thesis is a study of La Barbara’s treatment of the voice in these four early works. I will frame my discussion with theories of the acousmatic by Mladen Dolar and Brian Kane and will also draw comparisons with Helmut Lachnemann’s musique concrète instrumentale works. In doing so, I will chart La Barbara’s experimentation and use of the voice in its original function. Specifically, the voice as the first means expression, not requiring text or traditionally musical elements, but as an communicative wordless instrument.

description: Long Gamma-ray Bursts (GRBs) signal the death of massive stars. The afterglow emission can be used to probe the progenitor ambient through a detailed study of the absorption pattern imprinted by the circumburst material as well as the host galaxy interstellar medium on the continuum spectrum. This has been done at optical wavelengths with impressive results. Similar studies can in principle be carried out in the X-ray band, allowing us to shed light on the material metallicity, composition and distance of the absorber. We start exploiting this route through high resolution spectroscopy XMM-Newton observations of GRB 090618. We find a high metallicity absorbing medium (Z> 0.2 Zsun) with possible enhancements of S and Ne with respect to the other elements (improving the fit at a level of >3.4 sigma). Including the metallicity effects on the X-ray column density determination, the X-ray and optical evaluations of the absorption are in agreement for a Small Magellanic Cloud extinction curve.

description: Large language models (LMs) offer unprecedented language generation capabilities and exciting opportunities for interaction design. However, their highly context-dependent capabilities are difficult to grasp and are often subjectively interpreted. In this paper, we argue that by curating and analyzing large interaction datasets, the HCI community can foster more incisive examinations of LMs' generative capabilities. Exemplifying this approach, we present CoAuthor, a dataset designed for revealing GPT-3's capabilities in assisting creative and argumentative writing. CoAuthor captures rich interactions between 63 writers and four instances of GPT-3 across 1445 writing sessions. We demonstrate that CoAuthor can address questions about GPT-3's language, ideation, and collaboration capabilities, and reveal its contribution as a writing "collaborator" under various definitions of good collaboration. Finally, we discuss how this work may facilitate a more principled discussion around LMs' promises and pitfalls in relation to interaction design. The dataset and an interface for replaying the writing sessions are publicly available at https://coauthor.stanford.edu.

description: From air-sea gas exchange, oil pollution, to bioreactors, the ubiquitous fragmentation of bubbles/drops in turbulence has been modelled by relying on the classical Kolmogorov-Hinze paradigm since the 1950s. This framework hypothesizes that bubbles/drops are broken solely by eddies of the same size, even though turbulence is well known for its wide spectrum of scales. Here, by designing an experiment that can physically and cleanly disentangle eddies of various sizes, we report the experimental evidence to challenge this hypothesis and show bubbles are preferentially broken by the sub-bubble-scale eddies. Our work also highlights that fragmentation cannot be quantified solely by the stress criterion or the Weber number; The competition between different time scales is equally important. Instead of being elongated slowly and persistently by flows at their own scales, bubbles are fragmented in turbulence by small eddies via a burst of intense local deformation within a short time.

This report examines the following options for implementing environmental provisions of the CRP: o Irrigated land. Enrollment costs for this acreage are high since irrigation is profitable in many areas. Net environmental benefits would not likely increase. o Erodible land in watersheds with pollution problems. Water quality could benefit considerably by targeting selected watersheds. Targeting modest acreages of buffer strips near streams would increase benefits even more. o Cropped wetlands. Wildlife habitat would improve by restoring up to 6 million acres to wetlands.

description: The relationship between the axial structures of three-dimensional (3-D) targets and the signal of the remote-sensing techniques, such as the modulated echo waveform of the full-waveform light detection and ranging (FW-LiDAR), has been well established. However, the relationship between the lateral structures on modulated echo waveform has not been exploited in detail. For FW-LiDAR, the peak intensity, rather than the shape and width, of the echo waveform reflects lateral structural information. Using four typical two-dimensional shapes to approach the lateral structures, a mathematical formula bridging the peak intensity and the lateral structures is derived. Based upon the echo waveform simulated using the formula, modulations of the lateral structural information on the peak intensity are examined to establish a database of target properties, including shape, size and position. The physics regarding peak intensity dependence on target position is used for facile shape recognition. The modulation of the lateral shapes of ground and aerial targets on the FW-LiDAR can be assessed extensively following the procedure demonstrated in this paper. Owing to the conciseness, the peak intensity formula enables the retrieval of lateral structural information by inversion, promoting the applications of FW-LiDAR in domains including topological mapping, ecological monitoring and space debris detection and removal.
Predictability of Antarctic Sea Ice Edge on Subseasonal Time Scales

Publisher: name: FID GEO
Year: 2019

description: Coupled subseasonal forecast systems with dynamical sea ice have the potential of providing important predictive information in polar regions. Here, we evaluate the ability of operational ensemble prediction systems to predict the location of the sea ice edge in Antarctica. Compared to the Arctic, Antarctica shows on average a 30% lower skill, with only one system remaining more skillful than a climatological benchmark up to ∼30 days ahead. Skill tends to be highest in the west Antarctic sector during the early freezing season. Most of the systems tend to overestimate the sea ice edge extent and fail to capture the onset of the melting season. All the forecast systems exhibit large initial errors. We conclude that subseasonal sea ice predictions could provide marginal support for decision-making only in selected seasons and regions of the Southern Ocean. However, major progress is possible through investments in model development, forecast initialization and calibration.

description: We performed deep photometry of the central region of Galactic globular cluster M15 from archival Hubble Space Telescope data taken on the High Resolution Channel and Solar Blind Channel of the Advanced Camera for Surveys. Our data set consists of images in far-UV (FUV$_{140}$; F140LP), near-UV (NUV$_{220}$; F220W), and blue (B$_{435}$; F435W) filters. The addition of an optical filter complements previous UV work on M15 by providing an additional constraint on the UV-bright stellar populations. Using color-magnitude diagrams (CMDs) we identified several populations that arise from non-canonical evolution including candidate blue stragglers, extreme horizontal branch stars, blue hook stars (BHks), cataclysmic variables (CVs), and helium-core white dwarfs (He WDs). Due to preliminary identification of several He WD and BHk candidates, we add M15 as a cluster containing a He WD sequence and suggest it be included among clusters with a BHk population. We also investigated a subset of CV candidates that appear in the gap between the main sequence (MS) and WDs in FUV$_{140}-$NUV$_{220}$ but lie securely on the MS in NUV$_{220}-$B$_{435}$. These stars may represent a magnetic CV or detached WD-MS binary population. Additionally, we analyze our candidate He WDs using model cooling sequences to estimate their masses and ages and investigate the plausibility of thin vs. thick hydrogen envelopes. Finally, we identify a class of UV-bright stars that lie between the horizontal branch and WD cooling sequences, a location not usually populated on cluster CMDs. We conclude these stars may be young, low-mass He WDs.

description: Abstract The self-assembly of peptides onto the surface of gold nanoparticles has emerged as a promising strategy towards the creation of artificial enzymes. The resulting high local peptide density surrounding the nanoparticle leads to cooperative and synergistic effects, which result in rate accelerations and distinct catalytic properties compared to the unconjugated peptide. This Minireview summarizes contributions to and progress made in the field of catalytically active peptide–gold nanoparticle conjugates. The origin of distinct properties, as well as potential applications, are also discussed.

description: At the Large Hadron Collider (LHC), numerous events containing a Z~boson 
decaying into two muons are produced. In many of these events, the Z~boson is boosted and balanced in transverse momentum by exactly one jet.
Since the kinematical properties of the muons can be measured very precisely with the Compact Muon Solenoid (CMS) detector, such events are ideal candidates for a data driven technique for the absolute jet energy scale determination and calibration.

description: Landslides are destructive and recurrent natural disasters on steep slopes and represent a risk to lives and properties. Knowledge of relict landslides’ location is vital to understand their mechanisms, update inventory maps and improve risk assessment. However, relict landslide mapping is complex in tropical regions covered with rainforest vegetation. A new CNN framework is proposed for semi-automatic detection of relict landslides, which uses a dataset generated by a k-means clustering algorithm and has a pre-training step. The weights computed in the pre-training are used to fine-tune the CNN training process. A comparison between the proposed and the standard framework is performed using CBERS-04A WPM images. Three CNNs for semantic segmentation are used (Unet, FPN and Linknet) with two augmented datasets. A total of 42 combinations of CNNs are tested. Values of precision and recall were very similar between the combinations tested. Recall was higher than 75% for every combination, but precision values were usually smaller than 20%. False positives (FP) samples were addressed as the cause for these low precision values. Predictions of the proposed framework were more accurate and correctly detected more landslides. This work demonstrates that there are limitations for detecting relict landslides in areas covered with rainforest, mainly related to similarities between the spectral response of pastures and deforested areas with Gleichenella sp. ferns, commonly used as an indicator of landslide scars.

description: Farmland acreage in metropolitan counties rose by nearly half between 1974 and 1982 as metropolitan areas were redefined and additional counties were designated as metro. Metro farms are generally smaller, more land intensive in their production, more diverse, and more focused on high-value production than farms elsewhere. As of 1982, metro farms accounted for 29 percent of the U.S. total, 30 percent of total U.S. farm sales, and 16 percent of U.S. cropland.

description: An approach, based on Jucys--Murphy elements, to the representation theory of cyclotomic Hecke algebras is developed. The maximality (in the cyclotomic Hecke algebra) of the set of the Jucys--Murphy elements is established. A basis of the cyclotomic Hecke algebra is suggested; this basis is used to establish the flatness of the deformation without use of the representation theory.
Automated Fabrication of Elastomeric Prepregs for Soft Robotics Applications
Creators: name: Wienzek, Tristan

Publisher: name: FID GEO

description: Fluidic elastomer soft robots typically consist of a top and a strain-limiting bottom part. Both parts are usually cast and then glued together. Elastomeric prepregs, which can be stored at low temperatures for several months without significant cross-linking, simplify this manufacturing process. A cured top part of an arbitrary shape is placed on the wet prepreg, which later forms the strain-limiting layer, and the actuator is finally cured in an oven. Herein, a machine is designed and developed that automatically produces prepregs. Three different concepts are realized in a modular prototype: direct roller application, reverse roller application, and application with slot dies. Experiments show that the direct and the reverse roller application concepts are both suitable for the automated production of prepregs, where the latter one may be preferred due to the smaller number of contact surfaces. Three different textiles (polyester/cotton-blended fabric, nylon fabric, and fleece) are impregnated with the reverse roller application concept using Sylgard 184 and stored at −25 °C for 12 days. Using these prepregs, soft bending actuators are manufactured and tested for their functionality. Long-term fatigue tests show that only actuators produced with fleece prepregs are durable, without any signs of delamination.

description: Spallation is a typical fracture phenomenon in materials under dynamic loading, with its behavior significantly influenced by stress history, particularly strain rate. Exploring the mechanisms of spallation damage under different stress history and establishing corresponding failure models remain critical challenges in this field. This study investigates spallation in tantalum (Ta) under ramp wave unloading, revealing distinct damage mechanisms influenced by stress history. Unlike isentropic unloading, ramp waves generate segmented unloading and non-uniform strain rates, resulting in milder, widely distributed spallation damage. At flyer velocities exceeding 400 m/s, Ta exhibits multi-spallation with an anomalous 8.6% decrease in spall strength (5.8 GPa to 5.3 GPa). Wave propagation analysis shows interacting rarefaction waves create extended tensile regions, promoting dispersed damage and multi-spallation. Although spallation follows classical void nucleation-growth models, significant differences in void size/density emerge between spallation zones due to localized strain rate variations (higher rates suppress void growth). These findings highlight stress history’s critical role in governing damage distribution and failure modes, demonstrating how ramp wave-specific loading paths alter microvoid evolution dynamics. The work advances understanding of rate-dependent spallation mechanisms and provides a framework for modeling material failure under complex dynamic loading.

description: Dissipative properties of the electromagnetic environment as well as on-chip RC filtering are shown to suppress random state switchings in the two-junction superconductor(S) - normal metal(N) electron trap. In our experiments, a local high-ohmic resistor increased the hold time of the trap by up to two orders of magnitude. A strong effect of on-chip noise filtering was observed for different on-chip geometries. The obtained results are promising for realization of the current standard on the basis of the S-N hybrid turnstile.

description: Data-driven approaches, most prominently deep learning, have become powerful tools for prediction in many domains. A natural question to ask is whether data-driven methods could also be used to predict global weather patterns days in advance. First studies show promise but the lack of a common data set and evaluation metrics make intercomparison between studies difficult. Here we present a benchmark data set for data-driven medium-range weather forecasting (specifically 3–5 days), a topic of high scientific interest for atmospheric and computer scientists alike. We provide data derived from the ERA5 archive that has been processed to facilitate the use in machine learning models. We propose simple and clear evaluation metrics which will enable a direct comparison between different methods. Further, we provide baseline scores from simple linear regression techniques, deep learning models, as well as purely physical forecasting models. The data set is publicly available at https://github.com/pangeo-data/WeatherBench and the companion code is reproducible with tutorials for getting started. We hope that this data set will accelerate research in data-driven weather forecasting.

description: A partial order is universal if it contains every countable partial order as a suborder. In 2017, Fiala, Hubička, Long and Nešetřil showed that every interval in the homomorphism order of graphs is universal, with the only exception being the trivial gap $[K_1,K_2]$. We consider the homomorphism order restricted to the class of oriented paths and trees. We show that every interval between two oriented paths or oriented trees of height at least 4 is universal. The exceptional intervals coincide for oriented paths and trees and are contained in the class of oriented paths of height at most 3, which forms a chain.
