China Maritime Report No. 4: Civil Transport in PLA Power Projection

The People’s Liberation Army (PLA) has ambitious goals for its power projection capabilities. Aside from preparing for the possibility of using force to resolve Beijing’s territorial claims in East Asia, it is also charged with protecting China’s expanding “overseas interests.” These national objectives require the PLA to be able to project significant combat power beyond China’s borders. To meet these needs, the PLA is building organic logistics support capabilities such as large naval auxiliaries and transport aircraft. But it is also turning to civilian enterprises to supply its transportation needs.https://digital-commons.usnwc.edu/cmsi-maritime-reports/1003/thumbnail.jp

China Maritime Report No. 1: China’s Third Sea Force, The People’s Armed Forces Maritime Militia: Tethered to the PLA

Amid growing awareness that China’s Maritime Militia acts as a Third Sea Force which has been involved in international sea incidents, it is necessary for decision-makers who may face such contingencies to understand the Maritime Militia’s role in China’s armed forces. Chinese-language open sources reveal a tremendous amount about Maritime Militia activities, both in coordination with and independent of the People’s Liberation Army (PLA). Using well-documented evidence from the authors’ extensive open source research, this report seeks to clarify the Maritime Militia’s exact identity, organization, and connection to the PLA as a reserve force that plays a parallel and supporting role to the PLA. Despite being a separate component of China’s People’s Armed Forces (PAF), the militia are organized and commanded directly by the PLA’s local military commands. The militia’s status as a separate non-PLA force whose units act as “helpers of the PLA” (解放军的 助手) is further reflected in China’s practice of carrying out “joint military, law enforcement, and civilian [Navy-Maritime Law Enforcement-Maritime Militia] defense” (军警民联防). To more accurately capture the identity of the Maritime Militia, the authors propose referring to these irregular forces as the “People’s Armed Forces Maritime Militia” (PAFMM).https://digital-commons.usnwc.edu/cmsi-maritime-reports/1000/thumbnail.jp

China Maritime Report No. 6: Djibouti: China\u27s First Overseas Strategic Strongpoint

This China Maritime Report on Djibouti is the first in a series of case studies on China’s “overseas strategic strongpoints” (海外战略支点). The strategic strongpoint concept has no formal definition, but is used by People’s Republic of China (PRC) officials and analysts to describe foreign ports with special strategic and economic value that host terminals and commercial zones operated by Chinese firms.https://digital-commons.usnwc.edu/cmsi-maritime-reports/1005/thumbnail.jp

China Maritime Report No. 7: Gwadar: China\u27s Potential Strategic Strongpoint in Pakistan

This China Maritime Report on Gwadar is the second in a series of case studies on China’s Indian Ocean “strategic strongpoints” (战略支点). People’s Republic of China (PRC) officials, military officers, and civilian analysts use the strategic strongpoint concept to describe certain strategically valuable foreign ports with terminals and commercial zones owned and operated by Chinese firms.https://digital-commons.usnwc.edu/cmsi-maritime-reports/1006/thumbnail.jp

Pre-clinical validation of virtual bronchoscopy using 3D Slicer

Lung cancer still represents the leading cause of cancer-related death, and the long-term survival rate remains low. Computed tomography (CT) is currently the most common imaging modality for lung diseases recognition. The purpose of this work was to develop a simple and easily accessible virtual bronchoscopy system to be coupled with a customized electromagnetic (EM) tracking system for navigation in the lung and which requires as little user interaction as possible, while maintaining high usability. The proposed method has been implemented as an extension to the open-source platform, 3D Slicer. It creates a virtual reconstruction of the airways starting from CT images for virtual navigation. It provides tools for pre-procedural planning and virtual navigation, and it has been optimized for use in combination with a of freedom EM tracking sensor. Performance of the algorithm has been evaluated in ex vivo and in vivo testing. During ex vivo testing, nine volunteer physicians tested the implemented algorithm to navigate three separate targets placed inside a breathing pig lung model. In general, the system proved easy to use and accurate in replicating the clinical setting and seemed to help choose the correct path without any previous experience or image analysis. Two separate animal studies confirmed technical feasibility and usability of the system. This work describes an easily accessible virtual bronchoscopy system for navigation in the lung. The system provides the user with a complete set of tools that facilitate navigation towards user-selected regions of interest. Results from ex vivo and in vivo studies showed that the system opens the way for potential future work with virtual navigation for safe and reliable airway disease diagnosis

HEP Community White Paper on Software trigger and event reconstruction

Realizing the physics programs of the planned and upgraded high-energy physics (HEP) experiments over the next 10 years will require the HEP community to address a number of challenges in the area of software and computing. For this reason, the HEP software community has engaged in a planning process over the past two years, with the objective of identifying and prioritizing the research and development required to enable the next generation of HEP detectors to fulfill their full physics potential. The aim is to produce a Community White Paper which will describe the community strategy and a roadmap for software and computing research and development in HEP for the 2020s. The topics of event reconstruction and software triggers were considered by a joint working group and are summarized together in this document.Comment: Editors Vladimir Vava Gligorov and David Lang
