Subjects: Automotive catalytic converter, breakthrough innovation, Johnson Matthey

description: Can environmental legislation spur innovative response? This case describes the development of the automotive catalytic converter (ACC) at Johnson Matthey (JM), a precious metals company that entered the automotive industry as a component provider. The market was unfamiliar to JM and highly competitive, but in the 1970s the US Environmental Protection Agency (EPA) introduced standards for emissions control by automotive companies well ahead of current practice. Johnson Matthew responded to the prospect of market demand for a technology that could meet the regulations. The EPA policy of technology “forcing” stimulated collaboration for innovation among companies from a variety of industries. Our case evidence shows that the key innovator, JM, achieved its breakthrough as a result of proactive R&D management by the product champion together with sustained corporate support at a high level and partnership strategies.

description: Kernel-phase observables extracted from mid- to high-Strehl images are proving to be a powerful tool to probe within a few angular resolution elements of point sources. The attainable contrast is however limited by the dynamic range of the imaging sensors. The Fourier interpretation of images with pixels exposed beyond the saturation has so far been avoided. We show that in cases where the image is dominated by the light of a point source, we can use an interpolation to reconstruct the otherwise lost pixels with an accuracy sufficient to enable the extraction of kernel-phases from the patched image. We demonstrate the usability of our method by applying it to archive images of the Gl 494AB system, taken with the Hubble Space Telescope in 1997. Using this new data point along with other resolved observations and radial velocity measurements, we produce improved constraints on the orbital parameters of the system, and consequently the masses of its components.
Bragg-grating solitons in a semilinear dual-core system

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: We investigate the existence and stability of gap solitons in a double-core optical fiber, where one core has the Kerr nonlinearity and the other one is linear, with the Bragg grating (BG) written on the nonlinear core, while the linear one may or may not have BG. The model considerably extends the previously studied families of BG solitons. For zero-velocity solitons, we find exact solutions in a limiting case when the group-velocity terms are absent in the equation for the linear core. In the general case, solitons are found numerically. Stability borders for the solitons are found in terms of an internal parameter of the soliton family. Depending on frequency $ω$, the solitons may remain stable for large values of the group velocity in the linear core. Stable moving solitons are found too. They are produced by interaction of initially separated solitons, which shows a considerable spontaneous symmetry breaking in the case when the solitons attract each other.

Exploring the Constituents of Growth in a Technology Cluster: Evidence from Cambridge, UK

Year: 2019

description: High-growth firms appear to be key drivers of new industries and technologies. Here we investigate the contribution of these and other types of firm to a technology cluster, in the context of ‘creative destruction’ shaping the evolution of the cluster. Evidence on the reallocation of scarce resources through processes of creative destruction is scarce. But in a cluster the effects of creative destruction can be traced through such developments as (1) firm exits and entries (2) change in firm size distribution and (3) acquisition of firms. We apply churn analysis, firm size transition analysis and analysis of acquisition to the technology cluster in Cambridge UK over twenty years. Firm growth contributed two-thirds of all new job creation, while entry-exit turbulence accounted for one third of job creation. High-growth firms accounted for a quarter of jobs created in the Cambridge cluster during this period, without ever making up more than 3% of all tech firms. There has been an increase in average firm size and profitability. A fall in entry rates and fewer firms moving up into larger size categories in recent years point to adverse conditions for innovative new firms even before the financial crash.

Basic observables for the accelerated electron and its field

description: We revisit in the framework of the classical theory the problem of the accelerated motion of an electron, taking into account the effect of the radiation emission. We present results for the momentum and energy of the electromagnetic field of an accelerated electron for a spatial region excluding a vicinity of the electron and a procedure to compensate their singularities in the limit of the point electron. From them we infer expressions for the observables momentum and energy of the electron. They lead, together with those corresponding to the emitted radiation, to an equation of motion of the electron that coincides, in the case of an external electromagnetic field, with the Lorentz-Dirac equation. Based on the results for the linear momentum and using the same calculation method, we obtain the equations corresponding to the angular momentum of the electron and its field. While the formalism used is not wholly manifestly covariant, arguments based on relativistic covariance are invoked and used at appropriate places, where they play an essential role.
Nonlocality of Kohn-Sham exchange-correlation fields in dielectrics

description: The theory of the macroscopic field appearing in the Kohn-Sham exchange-correlation potential for dielectric materials, as introduced by Gonze, Ghosez and Godby, is reexamined. It is shown that this Kohn-Sham field cannot be determined from a knowledge of the local state of the material (local crystal potential, electric field, and polarization) alone. Instead, it has an intrinsically nonlocal dependence on the global electrostatic configuration. For example, it vanishes in simple transverse configurations of a polarized dielectric, but not in longitudinal ones.

description: Context: This thesis analyzes media coverage in Canada of environmentally displaced people (EDP) due to their recent prominence in political discussions on a national and international level as well as in the literature. Objectives: This thesis has three goals, notably (1) to raise awareness of EDP as a social phenomenon; (2) to understand how EDP are currently constructed in the public sphere; and (3) to analyze whether Canadian media characterizes EDP within discourses of victimization and/or devictimization. Ultimately, this thesis investigates: How does Canadian print media represent environmentally displaced people? Methodology: A total of 149 (132 English and 17 French) Canadian news articles, appearing from 2000 to 2017, were selected for analysis through a search strategy that included specific key words. The articles selected appeared in the Toronto Star, Globe & Mail, Montreal Gazette, Ottawa Citizen, Vancouver Sun, Le Journal de Québec, La Presse, and Canada Newswire. Results: The results were analyzed by using a frame analysis. Based on this analysis, a few key points were commonly used to represent EDP, including the uncertainty over which terms to use, their quantification, as well as a scare tactic to entice action towards climate change. Overall, the media tended to portray EDP using themes of devictimization. Conclusion: Future research should be conducted to continue to analyze media representations of those displaced. It is also imperative to collect more data on EDP in order to resolve the debate around their definition and officially recognize one term to help facilitate research and increase the legitimacy of those displaced - whether they are recognized as migrants or refugees.

description: The conformal algebra of a 1+3 decomposable spacetime can be computed from the conformal Killing vectors (CKV) of the 3-space. It is shown that the general form of such a 3-CKV is the sum of a gradient CKV and a Killing or homothetic 3-vector. It is proved that spaces of constant curvature always admit such conformal Killing vectors. As an example, the complete conformal algebra of a Gödel-type spacetime is computed. Finally it is shown that this method can be extended to compute the conformal algebra of more general non-decomposable spacetimes.

description: Dirac particles have been notoriously difficult to confine. Implementing a curved space Dirac equation solver based on the quantum Lattice Boltzmann method, we show that curvature in a 2-D space can confine a portion of a charged, mass-less Dirac fermion wave-packet. This is equivalent to a finite probability of confining the Dirac fermion within a curved space region. We propose a general power law expression for the probability of confinement with respect to average spatial curvature for the studied geometry.

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: We investigate by means of numerical simulations with nested Cartesian meshes the force exerted on a massive and luminous perturber moving at constant speed through a homogeneous and opaque gas, taking into account thermal diffusion in the gas and the radiative feedback from the perturber. The force arising from the release of energy into the ambient medium by the perturber, or heating force, is directed along the direction of motion and induces an acceleration of the perturber. Its value is compared to analytic estimates in the low and high Mach number limits, and found to match those accurately. In addition, the drag exerted on a non-luminous perturber significantly departs from the adiabatic expression when thermal diffusion is taken into account. In the limit of a vanishing velocity, this drag tends to a finite value which we determine using linear perturbation theory and corroborate with numerical simulations. The drag on a non-luminous perturber in a non-adiabatic gas therefore behaves like dry or solid friction. We work out the luminosity threshold to get a net acceleration of the perturber and find it to be generally much smaller than the luminosity of accreting low-mass planetary embryos embedded in a gaseous protoplanetary disc at a few astronomical units. We also present in some detail our implementation of nested meshes, which runs in parallel over several \emph{Graphics Processing Units} (GPUs).

A variant which we call R^+ is also known to turn an arbitrary initial configuration into a homogenous one (without changing the ones that were homogenous to start with). Here we show that R^+ always increases a certain property of sets called thickness. This result is intended as a step towards a proof of the fast convergence towards consensus under R^+. The latter is observable experimentally, even in the presence of some noise.

Several types of one soliton solutions of the corresponding N- wave equations and their reductions are studied. We show that to each soliton solution one can relate a (semi-)simple subalgebra of g. We illustrate our results by 4-wave equations related to so(5) which find applications in Stockes-anti-Stockes wave generation.

description: Abstract

Undernourishment remains a critical public health issue affecting both maternal and child health, particularly in resource-limited settings. This study examines the impact of undernourishment on mothers and children at Banadir Hospital, Mogadishu, Somalia. The research assesses the prevalence, causes, and health consequences of maternal and child malnutrition, with a focus on its short-term and long-term effects.

Using a cross-sectional study design, data was collected through structured questionnaires and interviews with mothers and healthcare professionals. The findings reveal that food insecurity, poverty, inadequate maternal education, and limited healthcare access significantly contribute to undernourishment. Additionally, undernourished mothers face higher risks of pregnancy complications, anemia, and poor birth outcomes, while their children experience low birth weight, stunted growth, and weakened immunity.

The study highlights the urgent need for targeted interventions, including improved maternal nutrition programs, enhanced healthcare services, and community-based nutritional support. Recommendations include strengthening hospital nutrition programs, increasing public health awareness, and implementing policies to ensure food security for vulnerable populations. These findings provide valuable insights for policymakers, healthcare providers, and organizations working to improve maternal and child health outcomes in Somalia.

Realizing the Potential of Advance Material Innovations

Publisher: name: Apollo - University of Cambridge Repository
Year: 2019

description: Advanced material technologies have received considerable attention from the media as potential engines of economic growth in an increasingly knowledge based economy. However, the extensive contributions of novel materials are not yet fully appreciated. Advanced materials have potential to enable other technologies and hence make a substantial and transformative impact on other industries and markets, including green technologies, healthcare, sustainable energy, construction, communications and defense. Like IT and biotech before them, advanced materials face many of the commercialization challenges of radical, generic technologies. Unlike their predecessor technologies, the value creation to which they could give rise is not readily demonstrated to their co-producers, customers or end consumers because of the complexity of their value chains and entrenched competition from incumbent products. This study investigates the market-oriented challenges facing AM University Spin-Outs (USO) and in particular, the evolution of their business models firm in response to other players. The choice of market and business model affects what value needs to be demonstrated to partners and can ultimately determine how much of a material’s potential value to society is realized. We build on the concept of innovation ecosystems to address these upstream innovations. A case study approach is used to elucidate the challenges that these ventures face. The findings highlight the way relationships between organizations can unlock the potential of entrepreneurial AM innovations. Partners are shown to be critical to a venture’s market selection and value chain positioning, determining not only what resources the venture can access but also the resource-base it needs to build to attract such partners. While current wisdom is that innovative ventures with radical technologies centre their activity on market niches, our cases show that potential partners, often large incumbent firms, may not be drawn by niche markets. Where substitute products already exist, ventures must adapt their business models to secure partner cooperation and clearly demonstrate the value they can offer

description: Excerpts from the report Summary: Research on the retail merchandising of agricultural products was greatly accelerated after the Congress passed the Agricultural Marketing Act of 1946. This report constitutes an appraisal and summary of the published research directly related to methods employed in the retail merchandising of agricultural products from August 1946 to September 1958. During that period, over 200 published reports have given results of research in this area. These studies have had the general objective of determining the relative effectiveness of specific merchandising methods in increasing the sales of and demand for farm products. An annotated bibliography of the publications reviewed in the course of this study is included. The research techniques most commonly used in conducting retail-store merchandising research were: (1) Surveys using observation of existing practices, interviews, or mail questionnaires; (2) matched-lot experiments; (3) test-store experiments; (4) test-versus-control-store experiments; and (5) controlled experiments employing statistical (experimental) designs, such as the latin square, randomized complete blocks, double change-over, and factorial design, to control or measure the influence of nonquantitative factors on the merchandising methods undergoing test.

In contrast to the case of coupling via the deformation potential, the leading contributions due to impurity-renormalized electron-phonon vertices are not exactly cancelled by processes of inelastic electron-impurity scattering. Electron energy relaxation time, diffusion correction to the conductivity, and phonon emission rate by hot electrons are computed for realistic $GaAs/AlGaAs$ heterostructures.

Generating Less Certain Adversarial Examples Improves Robust Generalization
Creators: name: Zhang, Minxing
name: Backes, Michael

Publisher: name: CISPA
Year: 2024

description: This paper revisits the robust overfitting phenomenon of adversarial training. Observing that models with better robust generalization performance are less certain in predicting adversarially generated training inputs, we argue that overconfidence in predicting adversarial examples is a potential cause. Therefore, we hypothesize that generating less certain adversarial examples improves robust generalization, and propose a formal definition of adversarial certainty that captures the variance of the model's predicted logits on adversarial examples. Our theoretical analysis of synthetic distributions characterizes the connection between adversarial certainty and robust generalization. Accordingly, built upon the notion of adversarial certainty, we develop a general method to search for models that can generate training-time adversarial inputs with reduced certainty, while maintaining the model's capability in distinguishing adversarial examples. Extensive experiments on image benchmarks demonstrate that our method effectively learns models with consistently improved robustness and mitigates robust overfitting, confirming the importance of generating less certain adversarial examples for robust generalization.
Peculiarities in the gravitational field of a filamentary ring

description: The gravitational field of a massive, filamentary ring is considered. We provide an analytic expression for the gravitational potential and demonstrate that the exact gravitational potential and its gradient, thus the gravitational force-field, is not central. Hence it is a good candidate to discuss the difference between the concepts of center of mass and center of gravity. We focus on other consequences of reduced symmetry, e.g., only the $z$-component of the angular momentum is conserved. However, the remnant high symmetry of this system also ensures that there are special classes of motions which are restricted to invariant subspaces, thus, depending on the initial condition, the dynamics of a point particle is integrable. We also show that periodic orbits in the equatorial plane external to the ring are possible, but only if the angular momentum is above a threshold value. In this case the orbits are stable.

description: How do advanced materials ventures overcome the daunting commercialization challenges of the sector: high technology and market uncertainty over long time frames, and the need for significant complementary assets and substantial financing? Does uncertainty enhance or obstruct value creation? To address these questions, this paper draws on research on value creation, technology commercialization, and, more specifically, advanced materials commercialization, and presents new evidence from a sample of 43 advanced materials ventures. The sample ventures are compared and analyzed to elucidate risk reduction and value creation strategies. The sample is subdivided into nanomaterials, performance materials, and fuel cell ventures through a hierarchical cluster analysis, and subgroup commercialization metrics are described and compared. We argue that embracing uncertainty enhances value creation for nanomaterials and performance materials ventures but diminishes value creation for fuel cell ventures. High value creators in our sample lend further support to this argument through their commercialization strategies: reduction of uncertainty by fuel cell ventures, and embracing uncertainty by nanomaterials ventures. All of the successful advanced materials ventures commercialize radical technologies, emphasize strategic alliances, and begin demonstrating value with near-term, substitution applications.

description: A liquid in contact with a textured surface can be found in two states, Wenzel and Cassie. In the Wenzel state the liquid completely wets the corrugations while in the Cassie state the liquid is suspended over the corrugations with air or vapor trapped below. The superhydrophobic properties of the Cassie state are exploited for self-cleaning, drug delivery etc., while in the Wenzel state most of these properties are lost; it is therefore of fundamental and technological interest to investigate the kinetics and mechanism of the Cassie-Wenzel transition. Computationally, the Cassie-Wenzel transition is often investigated using enhanced sampling techniques based on the use of collective variables (CVs). The choice of the CVs is a crucial task because it affects the free-energy profile, the estimation of the free-energy barriers, and the evaluation of the mechanism of the process. Here we investigate possible simulation artifacts introduced by common CVs adopted for the study of the Cassie-Wenzel transition: the average particle density in the corrugation of a textured surface and the coarse grained density field at various levels of coarse graining. We also investigate possible additional artifacts associated to finite size effects. We focus on a pillared surface. We show that the use of the average density of fluid in the interpillar region brings to severe artifacts in the relative Cassie-Wenzel stability and in the transition barrier. A proper description of the wetting mechanism and its energetics requires a rather fine discretization of the density field. Concerning the finite size effects, we have found that the typical system employed in the Cassie-Wenzel transition, containing a single pillar within periodic boundary conditions, prevents the break of translational symmetry of the liquid-vapor meniscus during the process.

description: Innovative financing for global health may stimulate new waves of entrepreneurial activity. Global policies have created new sources of financing to accelerate knowledge generation for healthcare in resource-poor settings. This article outlines the emerging research concerned with the entrepreneurial response to opportunities and incentives at the bottom of the pyramid for healthcare. Questions arise to what kind of business models can be used to provide affordable healthcare on a viable basis. We examine public-private partnerships as one mechanism to catalyze the ecosystem and draw in stakeholders to contribute to the innovation value chain. We integrate entrepreneurship, innovation and ecosystem theories to discuss how the entrepreneurial firm builds resources and creates value in the healthcare ecosystem.

description: Using several approximations, we calculate an estimate of the gravitational radiation emitted when two equal mass black holes coalesce at the end of their binary inspiral. We find that about 1% of the mass energy of the pair will emerge as gravitational waves during the final ringdown and a negligible fraction of the angular momentum will be radiated.

description: oil extraction and management are some of the major industrial maintenance processes in automotive servicing, and waste management. Increasing the efficiency of these processes help the industries minimize losses, optimize operations and promote environmental friendliness. This study is focusing on design, functionality, and application of oil suction machines that provide an environmental-friendly and efficient operation compared to conventional method of removing oil in the textile industry. This unit is designed with vacuum pumps, suction hoses, and integrated storage tanks, to be able to process rapid and precise oil extraction without major risk of spillages or contamination. This machine preserves the main compartment of sewing machine and it provides additional filtration systems to run for long duration, if any, which allow partial reutilization of oils through the removal of possible contaminants like sludge and metals. Applications differ in industries mainly in service and waste oil recycling, which shows that they play their role in helping improve efficient maintenance and promoting the circular economic principles. The study further highlights the environmental and economic benefits of oil suction machines, as these machines help in resource conservation, workplace safety, and cost reduction. The limitations of the current design that need future improvement are the limitations on capacity, high upfront costs, and periodic maintenance are acknowledged as areas for improvements. Further technological developments, such as IoT-enabled monitoring, AI-based predictive maintenance, and solar-powered design are discussed as potential upgrades to enhance the performance, sustainability, and accessibility of oil suction machines. This project work exposes valuable insight into the reliability and limits of the oil suction pump compartment. It is offering a foundation for further research and innovational developments aimed at oil handling and management technologies.

description: Massive early-type galaxies follow a tight relation between the mass of their central supermassive black hole ($\rm M_{BH}$) and their stellar mass ($\rm M_{\star}$). The origin of observed positive outliers from this relation with extremely high $\rm M_{BH}$ ($> 10^{9} M_{\odot}$) remains unclear. We present a study of such outliers in the Hydrangea/C-EAGLE cosmological hydrodynamical simulations, designed to enable the study of high-mass galaxy formation and evolution in cluster environments. We find 69 $M_{\rm BH}(M_{\star})$ outliers at $z=0$, defined as those with $ \rm M_{BH} >10^{7} M_{\odot}$ and $\rm M_{BH}/\rm M_{\star}> 0.01$. This paper focusses on a sample of 5 extreme outliers, that have been selected based on their $\rm M_{BH}$ and $\rm M_{\star}$ values, which are comparable to the most recent estimates of observed positive outliers. This sample of 5 outliers, classified as `Black hole monster galaxies' (BMGs), was traced back in time to study their origin and evolution. In agreement with the results of previous simulations for lower-mass $\rm M_{BH}(\rm M_{\star})$ outliers, we find that these galaxies became outliers due to a combination of their early formation times and tidal stripping. For BMGs with $\rm M_{BH} > 10^9 M_{\odot}$, major mergers (with a stellar mass ratio of $μ> 0.25$) at early times ($z>2$) precede the rapid growth of their supermassive BHs. Furthermore, the scatter in the relation between $\rm M_{BH}$ and stellar velocity dispersion, $σ$, correlates positively with the scatter in [Mg/Fe]($σ$). This indicates that the alpha enhancement of these galaxies, which is closely related to their star formation history, is related to the growth of their central BHs.

description: This paper presents an analysis of the security risks faced by RCDM Repair Center, a fictional organization that provides repair services for various devices. The paper uses the Common Vulnerability Scoring System (CVSS) to assess the severity and impact of different types of vulnerabilities, both internal and external, that affect the organization's operations and assets. The paper also proposes a remediation strategy based on a hierarchical table that prioritizes the most critical and urgent vulnerabilities and suggests appropriate solutions. The paper aims to demonstrate the benefits and limitations of CVSS as a tool for vulnerability management and to explore alternative methods that can complement or improve CVSS. So, keeping in mind all the values, vulnerabilities and solutions RCDM Repair Centre needs an urgent computer network and system restructuring project to make sure their security. The above research details and assessment details also show the currently available vulnerabilities and why you need to fix these vulnerabilities in a timely manner. After we fixing process on vulnerabilities. As a result, RCDM Repair Centre potentially can operate their computer system and network without facing any issues or trust issues regarding the cyber security and this will also enhance the organizational internal employee confidence and productivity. So, this assessment will not only help hm to improve better but by bettering his computer system and network-based problems and this will be a good thing to increase his profits as well. As a last point, patching these vulnerabilities immediately allows them to improve their computer systems and networks.
