Objectives Thoracic endovascular aortic repair (TEVAR) is the standard of care for descending thoracic aortic aneurysms (DTAA), and newer generation stent grafts have significant design improvements compared to earlier generation devices. Methods We report the first commercial use of the Medtronic Valiant Navion stent graft for treatment of an 85-year-old woman with a 5.8 cm DTAA and a highly tortuous thoracic aorta. Results A percutaneous TEVAR was performed using a two-piece combination of the Valiant Navion FreeFlo and CoveredSeal stent graft configurations for zones 2–5 coverage. The devices were successfully delievered through highly tortuous anatomy and deployed, excluding the entire length of the aneurysm with precise landing, excellent apposition and no evidence of endoleak. The patient tolerated the procedure well and has had no stent graft-related complications through one-year follow-up. Conclusions Design enhancements such as a lower profile delivery system, better conformability, and a shorter tapered tip are some of the improvements to this third-generation TEVAR device. Coupled with the multiple configuration options available, this gives physicians a better tool to treat thoracic aortic pathologies in patients with challenging anatomy. The early results are encouraging, and evaluation of long-term outcomes will continue.

PurposeAlthough the global construction industry has made great contributions to economic development, industry corruption is a challenge for governments all over the world. This paper aims to investigate the causal complexity of organizational corruption by exploring the configuration effect of multiple induced conditions of corruption in the construction sector.Design/methodology/approachThis study is focused on bribery, a specific form of corrupt behavior through a scenario-based survey role-playing game in which participants encounter bribery. A total of 400 Chinese construction sector participants were randomly recruited to complete this survey.FindingsCompared with studies that have identified a number of factors associated with corruption in the construction sector, this study found asymmetry and complexity in the causality of organizational corruption. That is, when a variable causing corruption changes from one condition to its opposite – for example, from fierce to mild competition – the degree of corruption is not necessarily reduced as one may expect.Practical implicationsAnti-corruption measures should not rely solely on the net effects of discrete conditions and the interactions between multiple factors should not be ignored. In other words, anti-corruption strategies should not be implemented in isolation of their context, and pairing control measures with configurations is critical in controlling corruption. Finally, multiple configuration paths should be reconsidered when considering the degree of corruption reduction.Originality/valueThis study proposes a comprehensive analysis framework for addressing organizational corruption in the construction sector by investigating configuration effects of multiple induced conditions and offers a useful method for addressing corruption.

AbstractProgrammable integrated photonic circuits have been called upon to lead a new revolution in information systems by teaming up with high speed digital electronics and in this way, adding unique complementary features supported by their ability to provide bandwidth-unconstrained analog signal processing. Relying on a common hardware implemented by two-dimensional integrated photonic waveguide meshes, they can provide multiple functionalities by suitable programming of their control signals. Scalability, which is essential for increasing functional complexity and integration density, is currently limited by the need to precisely control and configure several hundreds of variables and simultaneously manage multiple configuration actions. Here we propose and experimentally demonstrate two different approaches towards management automation in programmable integrated photonic circuits. These enable the simultaneous handling of circuit self-characterization, auto-routing, self-configuration and optimization. By combining computational optimization and photonics, this work takes an important step towards the realization of high-density and complex integrated programmable photonics.
