TL;DR: In this article, the authors investigated the formation of singularities and the existence of peaked traveling-wave solutions for a modified Camassa-Holm equation with cubic nonlinearity.
Abstract: In this paper, we investigate the formation of singularities and the existence of peaked traveling-wave solutions for a modified Camassa-Holm equation with cubic nonlinearity. The equation is known to be integrable, and is shown to admit a single peaked soliton and multi-peakon solutions, of a different character than those of the Camassa-Holm equation. Singularities of the solutions can occur only in the form of wave-breaking, and a new wave-breaking mechanism for solutions with certain initial profiles is described in detail.

TL;DR: Simulation results show that the proposed adaptive multisensor scheduling scheme can achieve superior energy efficiency and tracking reliability while satisfying the tracking accuracy requirement, and is also robust to the uncertainty of the process noise.
Abstract: Due to uncertainties in target motion and limited sensing regions of sensors, single-sensor-based collaborative target tracking in wireless sensor networks (WSNs), as addressed in many previous approaches, suffers from low tracking accuracy and lack of reliability when a target cannot be detected by a scheduled sensor. Generally, actuating multiple sensors can achieve better tracking performance but with high energy consumption. Tracking accuracy, reliability, and energy consumed are affected by the sampling interval between two successive time steps. In this paper, an adaptive energy-efficient multisensor scheduling scheme is proposed for collaborative target tracking in WSNs. It calculates the optimal sampling interval to satisfy a specification on predicted tracking accuracy, selects the cluster of tasking sensors according to their joint detection probability, and designates one of the tasking sensors as the cluster head for estimation update and sensor scheduling according to a cluster head energy measure (CHEM) function. Simulation results show that, compared with existing single-sensor scheduling and multisensor scheduling with a uniform sampling interval, the proposed adaptive multisensor scheduling scheme can achieve superior energy efficiency and tracking reliability while satisfying the tracking accuracy requirement. It is also robust to the uncertainty of the process noise.

TL;DR: In this article, the authors identify key differences between product and capital markets related to information environment, time structure of transactions, and linkages between buyers and sellers, and suggest possible mechanisms that managers can employ to mitigate CMLOF and overcome investors' "home bias".
Abstract: The accelerating pace of global capital market integration has provided new opportunities for firms to raise capital abroad through global debt issues, cross-listings, and initial public offerings in foreign stock exchanges. However, existing empirical evidence suggests that foreign firms tend to be at a disadvantage compared with domestic firms, and they often suffer from investors’ “home bias”. The objective of this paper is to understand why firms are facing problems when accessing capital in foreign markets, and possible mechanisms that can help to mitigate these problems. It expands the liability of foreignness (LOF) research beyond the product market domain to include liabilities faced by firms attempting to secure resources in foreign capital markets. We identify key differences between product and capital markets related to information environment, time structure of transactions, and linkages between buyers and sellers. We analyze institutional distance, information asymmetry, unfamiliarity, and cultural differences as the main sources of capital market LOF (CMLOF). We suggest possible mechanisms that managers can employ to mitigate CMLOF and overcome investors’ “home bias”: bonding, signaling, organizational isomorphism, and reputational endorsements. We also outline directions for further theoretical and empirical development of the CMLOF research.

TL;DR: A photophysical study is reported for the trinuclear copper(I) complex, which can be tuned to multiple visible colors by controlling the temperature, solvent, and {[3,5-(CF3)2Pz]Cu}3 concentration, giving rise to Luminescence thermochromism, luminescence solvatochromist, and a new optical phenomenon called "concentration luminochromism" respectively.
Abstract: A photophysical study is reported for the trinuclear copper(I) complex {[3,5-(CF3)2Pz]Cu}3. The neutral compound exhibits multicolor bright phosphorescent emissions both in the solid state and in solution. The emission can be tuned to multiple visible colors by controlling the temperature, solvent, and {[3,5-(CF3)2Pz]Cu}3 concentration, giving rise to luminescence thermochromism, luminescence solvatochromism, and a new optical phenomenon called “concentration luminochromism”, respectively.

TL;DR: Effective secondary prevention of work disability will require research to develop cost-effective, multipronged approaches that concurrently target both worker-related and workplace psychosocial risk factors.
Abstract: Introduction: Psychosocial factors are important contributors to work disability associated with musculoskeletal conditions. The primary objectives of this paper were 1) to describe different psychosocial interventions that have been developed to prevent prolonged work disability, and 2) to identify future research directions that might enhance the impact of programs targeting psychosocial risk factors for work disability. Methods: Selective review of scientific literature on psychosocial and behavioral interventions and work disability. Results: Most prior interventions focused on psychosocial risk factors that exist primarily within the individual (e.g., pain catastrophizing, beliefs, expectancies). Successful disability prevention will require methods to assess and target psychosocial risk factors “outside” of the individual (e.g., interpersonal conflict in the workplace, job stress, etc.) using cost-effective, multipronged approaches. Research to explore interactions among different domains of psychosocial risk factors in relation to RTW outcomes is needed. Challenges to effective secondary prevention of work disability include developing competencies to enable a range of providers to deliver interventions, standardization of psychosocial interventions, and maximizing adherence to intervention protocols. Conclusion: Effective secondary prevention of work disability will require research to develop cost-effective, multipronged approaches that concurrently target both worker-related and workplace psychosocial risk factors.
