The MISP project (MIsure Sperimentali nei corsi d’acqua del Distretto delle Alpi Orientali per la cattura dei rifiuti e delle Plastiche galleggianti – Experimental measures in Eastern Alps District waterways for the capture of floating waste and plastics) aims to improve knowledge of waste and plastic pollution and to reduce floating waste in the Venice Lagoon and in selected rivers flowing into it, consequently limiting the arrival of floating garbage in the north part of the Adriatic Sea.The project is financed by the Italian Ministry of the Environment and Energy Security under Law No. 60/2022 (“SalvaMare” Law) and is coordinated by the Eastern Alps District – River basin Authority (Autorità di Bacino Distrettuale delle Alpi Orientali).MISP project, for the purpose of reduce plastic pollution, includes two main experimental measures, which are: positioning of three floating waste capture barriers in three different rivers of the catchment draining into the Venice Lagoon, and the construction and operation of a prototype boat equipped with technology for capturing floating waste in the Venice Lagoon.The Venice Lagoon is an extremely valuable and complex environment from both a naturalistic and cultural perspective. Together with the city of Venice, the lagoon is part of the UNESCO World Heritage Site and is included in the Natura 2000 network. This particular aquatic environment is affected by multiple anthropogenic pressures, among which plastic waste pollution is one of the most critical. Increasing knowledge of the quantity, distribution and movement of floating plastic waste is essential for planning effective mitigation actions.A core component of the MISP project is a tracking activity aimed at studying floating plastic pathways within the Venice Lagoon and identifying accumulation areas that will be important for the boat operation. During 2025 and early 2026, about 170 GPS trackers have been deployed at different locations in the lagoon and at selected river mouths. The trackers are designed to simulate the floating plastic waste targeted by the project and consist of floating plastic jars containing a GPS device. Each tracker can transmit its position every 18 hours, and the collected data are visualized and analysed through a WebGIS platform that reconstructs trajectories and supports spatial analysis.Data analysis through the WebGIS will provide various results, such as: waste transport dynamics and accumulation patterns in the study area, average distance travelled by floating waste, environmental conditions that influence the movement or retention of floating litter (e.g. wind, tides, storms, shoreline vegetation, and lagoon hydrodynamics).All these results will enable a more efficient waste collection with the project boat and a future sharing of them with local stakeholders will be useful for other waste collection initiatives in the project area.

Groundwater contamination has prompted the Environmental Protection Agency to consider restricting atrazine use, highlighting the need for alternative preemergence herbicides in grain sorghum. Research was conducted in 2023 and 2024 to evaluate grain

Abstract The Environmental Protection Agency has proposed increased restrictions and lower application rates for atrazine. Corn growers need to have options for weed control and increased scrutiny of atrazine may limit effective photosystem II-inhibiting herbicides. One alternative is the premixture of amicarbazone and metribuzin. The atrazine label prohibits planting soybean until the following year, limiting producers to replanting corn or grain sorghum after a failed stand. Amicarbazone allows a four-month soybean rotation interval, potentially enabling planting of the crop the same season as failed corn. Therefore, research was conducted in 2023 and 2024 in Fayetteville, AR, to evaluate soybean tolerance to an amicarbazone and metribuzin premixture after a simulated failed corn stand. Amicarbazone was applied at 245, 490, and 735 g ai ha -1 alone and in combination with metribuzin at 140, 280, and 420 g ai ha -1 . Soybean was planted following at least 1.3 cm of rainfall, (19-20 days after application). The label allows amicarbazone and metribuzin to be applied to corn at 336 and 190 g ha -1 , respectively, on silt loam soil with organic matter at 1.5 to 2%. The combination of amicarbazone and metribuzin at 735 and 420 g ha -1 , respectively, more than twice the labeled rate for corn, induced 61 to 91% soybean injury 14 days after emergence (DAE). When amicarbazone and metribuzin rates were reduced to 245 and 140 g ha -1 , respectively, the injury was 4% in both years, 14 DAE. Yield reductions were only seen in treatments with amicarbazone at 735 g ha -1 applied alone or in combination with metribuzin at 420 g ha -1 . Overall, crop response and yield reductions should be expected with an amicarbazone and metribuzin premixture at the highest rates used in this study. However, the label for the premixture will not allow these rates to be applied.

The ScIDEP Collaboration is constructing muon telescopes based on scintillator technology to investigate the internal structure of the Egyptian Pyramid of Khafre at Giza near Cairo using cosmic-ray muons. The collaboration aims to scan the pyramid from multiple viewpoints, both inside the king’s burial chamber that is located centrally at the base of the pyramid, and outside of the pyramid, to potentially identify any new internal structures. An overview of the project is presented, including the development of the data-acquisition system, the simulation framework, and very first detector studies.

The COmpact detectoR for the Eic (CORE) Proposal was submitted to the EIC "Call for Collaboration Proposals for Detectors". CORE comprehensively covers the physics scope of the EIC Community White Paper and the National Academies of Science 2018 report. The design exploits advances in detector precision and granularity to minimize size. The central detector includes a 3Tesla, 2.5m solenoid. Tracking is primarily silicon. Electromagnetic calorimetry is based on the high performance crystals. Ring-imaging Cherenkov detectors provide hadronic particle identification.

In this article we describe the design and preliminary measurement results of a new genetic algorithm (GA) based software package designed to optimize the timing performance of switch capacitor array waveform digitizers. We will report on the vast improvements in performance from previous methods and provide results for the optimization of two different waveform digitizers.

Abstract : All available sound velocity data in the North Indian Ocean (north of 10 degrees S latitude) were analyzed in terms of annual areal extent and depth of perturbations above deep axial depth, annual average depth and velocity of the deep sound channel and critical depth for the northeast and southwest monsoons. The vertical extent of these and other sound velocity features is shown on six north-south and six east-west cross-sections that extend to a maximum depth of 5000 meters. These analyses indicate that highly saline Red Sea Intermediate Water (RSIW) is the major factor controlling sound velocity structures in the North Indian Ocean. Mixing of RSIW with low salinity water masses causes either sporadic perturbations or an essentially isovelocity layer above deep axial depth. In relatively high concentrations, RSIW causes an anomalously deep (greater than 1700 meters) and narrow sound channel with velocities greater than 1493 meters/second (Gulf of Aden, Arabian Sea, and Arabian Basin.
