Integrating ATM and air transport into multimodal transport system for Door-to-Door travel: the X-TEAM D2D project proposed approach

The project designed ConOps has been finally validated by the construction of a simulation model of a high-level D2D case study, with the aim of assessing the performances, feasibility and limitations of the ConOps and identifying the areas of improvement between ATM and the different modes of transport. The simulation model included two parts: the regional airport and related addressed surrounding area (namely Brunswick, served by Hannover airport) and the hub airport and relatedaddressed surrounding area (namely Haarlem, served by Schiphol airport). The simulation model maintained the same structure but included different transport options in 2025, 2035 and 2050. The model implemented both the different existing transport options and perspective transfer possibilities compliant with the X-TEAM D2D designed ConOps, using real-life distances (GIS-Based) and reallife travel times (GIS-based) for the existing possibilities. It included moving objects (carrying info), such as passenger groups and transport entities, and static elements (Capacitated nodes), such as transport network and transfer stations

Integrating ATM and air transport into multimodal transport system for Door-to-Door travel: the X-TEAM D2D project proposed approach

The X-TEAM D2D project activities have been successfully concluded in 2022 and delivered several relevant results. First, the project provided the definition of future scenarios and use cases for the integration of the vertical transport with the surface transport towards integrated intermodal transport system and the identification of the resulting barriers. Based on that, the project carried out the design of the ConOps for integration of ATM and aviation, as well as UTM and UAM, in intermodal transport infrastructure and the parallel and cooperative design of the ConOps for the integration of ATM and UTM into overall intermodal service to passengers. The resulting overall ConOps for the seamless integration of ATM and air transport into an overall intermodal network, including other available transportation means (surface, water), to support the door-to-door connectivity has been finally successfully validated by means of dedicated simulation environment setup by the project as well as external experts assessment. The validation results indicated the feasibility and effectiveness of the proposed ConOps in achieving its target as well as allowed providing suggestions for its future development and improvement, beyond the project scope

An Outline of A Concept of Operations fFor Integration of ATM and Air Transport into Multimodal Transport System for Door-fo-Door Travel

In the framework of the research activities supported by SESAR JU, dedicated research stream is devoted to investigation of integration of Air Traffic Management (ATM) and aviation into a wider transport system able to support the implementation of Door-to-Door (D2D) travel concept. In this framework, the project X-TEAM D2D (Extended ATM for Door-to-Door Travel) has been funded by SESAR JU under the call SESAR-ER4-10-2019: ATM Role in Intermodal Transport, with Grant Agreement n. 891061. The project aims defining, developing and initially validating a Concept of Operations (ConOps) for the seamless integration of ATM and air transport into an overall intermodal network, including other available transportation means (surface, water), to support the door-to-door connectivity, in up to 4 hours, between any location in Europe, in compliance with the target assigned by the ACARE SRIA FlightPath 2050 goals. The project is focused on the consideration of ConOps for ATM and air transport integration in intermodal transport network serving urban and extended urban (up to regional level) mobility, taking into account the transportation and passengers service scenarios envisaged for the next decades, according to baseline (2025), intermediate (2035) and final (2050) time horizons. In this paper, the outcomes of the first phase of the project activities, aimed to provide the initial definition (concept outline) of the proposed overall ConOps are illustrated, emphasizing the specific activities that have been carried out up to date and the related achievements. In addition, an outlook is provided in the paper on the next project activities, expected to be carried out towards the conclusion of the studies and the validation, by means of dedicated numerical simulation campaigns, of the proposed ConOps

Synthesis of the C(7)–C(22) Sector of (+)-Acutiphycin via O‑Directed Double Free Radical Alkyne Hydrostannation with Ph₃SnH/Et₃B, Double I–Sn Exchange, and Double Stille Coupling

Herein a new double O-directed free radical hydrostannation reaction is reported on the structurally complex dialkyldiyne <b>11</b>. Through our use of a conformation-restraining acetal to help prevent stereocenter-compromising 1,5-H-atom abstraction reactions by vinyl radical intermediates, the two vinyl­stannanes of <b>10</b> were concurrently constructed with high stereocontrol using Ph₃SnH/Et₃B/O₂. Distannane <b>10</b> was thereafter elaborated into the bis-vinyl iodide <b>9</b> via O-silylation and double I–Sn exchange; double Stille coupling of <b>9</b>, O-desilylation, and oxidation thereafter furnished <b>8</b>

The Absolute Configuration for Inthomycin C: Revision of Previously Published Work with a Reinstatement of the (3<i>R</i>)‑Configuration for (−)-Inthomycin C

Stereochemical evidence is presented to demonstrate that (−)-inthomycin C has (3<i>R</i>)- and not (3<i>S</i>)-stereochemistry. Careful reappraisal of the previously published work− now indicates that the Hatakeyama, Hale, Ryu, and Taylor teams <i>all</i> have synthesized (−)-(3<i>R</i>)-inthomycin C. The newly measured [α]_D of pure (−)-(3<i>R</i>)-inthomycin C (98% ee) is −7.9 (<i>c</i> 0.33, CHCl₃) and not −41.5 (<i>c</i> 0.1, CHCl₃) as was previously reported in 2012
