[en] The Geostationary Lightning Mapper (GLM) instrument on the GOES-R series of geostationary weather satellites operated by NASA/NOAA is the first optical lightning location instrument to operate from geostationary orbit. It provides the opportunity to monitor lightning activity over an area in excess of 100 million square kilometres continuously using a single instrument, with the coverage of the GOES-16 GLM extending from South America up to Southern Canada, and from the East Pacific to near the West Coast of Africa. The Met Office, in partnership with US partners, has a responsibility to provide automated global gridded hazard forecasts for cumulonimbus (Cb) clouds for strategic flight planning as part of the World Area Forecast Service (WAFS). Therefore, this new satellite lightning capability provides a new opportunity to assess the performance of deterministic and probabilistic forecasts of convection for aviation users over remote regions with limited datasets of observations. Additionally, the new data can be used to calibrate the Met Office’ prototype probabilistic global Cb forecast product. GLM data from the GOES-16 satellite has been collected by the Met Office, with a view to assessing the characteristics and performance of the instrument and data produced. Data from May 2018 to January 2019 has been assessed and compared to data from the Met Office ATDnet lightning location system (LLS). ATDnet is a ground-based, longrange LLS, using 10 sensors distributed across Europe to detect electromagnetic waves in the very low frequency (VLF) spectrum created by lightning. Results of this comparison and features (e.g. errors suspected to be caused by solar impacts on the sensor and satellite manoeuvres) of the GLM data are discussed. (author)

[en] It is argued that detection of heavy leptons at the Superconducting Super Collider seems to be very difficult but perhaps not impossible. The feasibility is shown to depend critically upon the ability to identify events with W's decaying hadronically and missing transverse momentum

[en] Detailed vascular anatomy of the abdomen and pelvis is presented. Images were obtained on 0.3-T permanent magnet using spin-echo technique (SE 300/18). Consistently well visualized are the aorta, inferior vena cava, superior mesenteric artery, superior mesenteric vein, renal arteries and veins, portal system, hepatic veins, internal and external iliac. Even smaller vessels are frequently seen. The inferior mesenteric artery, inferior mesenteric vein, left and right gonadal veins, left adrenal vein, left gastric artery and coronary vein, and pancreatico-duodenal arcades may be clearly seen. The appearances of these vessels in coronal and sagittal planes are particularly emphasized. Statistical analysis of the frequency with which each of the vessels mentioned is visualized in 100 patients is presented

[en] This Air Pollution Control System (APCS) Conceptual Design and Evaluation study was conducted to evaluate a high-performance (APC) system for minimizing air emissions from mixed waste thermal treatment systems. Seven variations of high-performance APCS designs were conceptualized using several design objectives. One of the system designs was selected for detailed process simulation using ASPEN PLUS to determine material and energy balances and evaluate performance. Installed system capital costs were also estimated. Sensitivity studies were conducted to evaluate the incremental cost and benefit of added carbon adsorber beds for mercury control, specific catalytic reduction for NO_x control, and offgas retention tanks for holding the offgas until sample analysis is conducted to verify that the offgas meets emission limits. Results show that the high-performance dry-wet APCS can easily meet all expected emission limits except for possibly mercury. The capability to achieve high levels of mercury control (potentially necessary for thermally treating some DOE mixed streams) could not be validated using current performance data for mercury control technologies. The engineering approach and ASPEN PLUS modeling tool developed and used in this study identified APC equipment and system performance, size, cost, and other issues that are not yet resolved. These issues need to be addressed in feasibility studies and conceptual designs for new facilities or for determining how to modify existing facilities to meet expected emission limits. The ASPEN PLUS process simulation with current and refined input assumptions and calculations can be used to provide system performance information for decision-making, identifying best options, estimating costs, reducing the potential for emission violations, providing information needed for waste flow analysis, incorporating new APCS technologies in existing designs, or performing facility design and permitting activities

[en] The authors provide a mini-guide to some of the possible manifestations of weak-scale supersymmetry. For each of six scenarios they provide: (1) a brief description of the theoretical underpinnings; (2) the adjustable parameters; (3) a qualitative description of the associated phenomenology at future colliders; (4) comments on how to simulate each scenario with existing event generators

[en] The authors have developed a solid-state, personal computer-based image digitization and transmission system that uses the integrated services digital network (ISDN), a technology under intensive development for ultra-high-speed data transmission over normal telephone lines. Using the prototype system, they have transmitted thousands of images from their hospital to a remote review site over 15 miles away, achieving data rates of 8,000 bytes (64,000 bits) per second with nearly perfect accuracy. They are presently modifying the system software to increase the data rate of 16,000 bytes (128,000 bits) per second

[en] The authors comment on heavy lepton searches at the SSC. There are three relevant production mechanisms for the heavy leptons. The feasibility to detect these heavy leptons depends critically upon the ability to identify events with W's decaying hadronically and missing transverse momentum

[en] One of the options for an accelerator beyond the LHC is a hadron collider with higher energy. Work is going on to explore accelerator technologies that would make such a machine feasible. This workshop concentrated on the physics and detector issues associated with a hadron collider with an energy in the center of mass of the order of 100 to 200 TeV
