OpenSSP, standing for Open Single-Scattering Properties, is first a database of numerically grown or constructed, realistic solid hydrometeors and their (scalar) single scattering properties (SSPs), and secondly a web interface (portal) to the database for interested researchers to obtain particle structure(s) and their corresponding SSPs. We started the OpenSSP web interface around 2016. It was programmed in JavaScript (JS) and hosted by the Precipitation Processing System (PPS) of NASA. However, the original developer left in 2018, and the JS-based web interface started falling out of date. By 2023, some most useful functions of the portal became unreliable, for example, getting SSPs for an ensemble of particles specified by a particle size distribution (PSD) and/or a mass-dimensional (m-D) relation.NASA's Global Precipitation Mission (GPM) and the Atmospheric Observing System (AOS) projects provided in 2023 support for the renewal of OpenSSP as the first step toward a much richer NASA Particle and Single-Scattering Database, PaSS DB, which will feature an augmented non-liquid hydrometeor collection, including melting hydrometeors and additional solid hydrometeors, with polarimetric SSPs for multiple particle orientations. We also envision a mechanism for NASA PaSS to accept community contributions to the database and to include other non-spherical particle species, such as aerosol, dust, or salt particles.OpenSSP is now back in operation at a different URL, https://ParticleScattering.org. (The original URL, https://storm.pps.eosdis.nasa.gov/storm/OpenSSP.jsp, is now defunct.) The following are some notable changes. OpenSSP used to use an HDF file as a convenient substitute for a database management system (DBMS); it now employs a bona fide relational DBMS, PostgresQL, to offer better performance in anticipation for the vastly increased data volume of NASA PaSS DB. We have also tweaked the graphical interface to make OpenSSP more intuitive and useable.

The study focused on climate change policy implementation gaps among smallholder farmers in Laikipia County in Kenya. Climate change policies were developed by national and county governments to support climate change mitigation and adaptation in order to enhance food security and community resilience. However, little is known about the gaps in implementation of these policies among communities, which are severely affected by impacts of climate change. Using semi-structured household questionnaires, focused group discussion and key informant interviews with a sample of smallholder farmers and stakeholders drawn during community-led initiatives, local administration meetings and agricultural extension workshops in Laikipia County, results show that a wide range of policies on tree planting, water management, forest conservation and riparian and riverine protection were communicated by county and national governments, but only few of the smallholder farmers implemented them, thereby causing a very wide policy-practice gap.

Information is a major determinant of outcomes in aerospace engineering. But, how does information influence decision-making processes, such as an individual's interpretation, meaning, and actions of it? This paper uses Stephen Ross's principal-agent theory in the context of the 1986 Challenger disaster. In the model, agents choose which anomalies are manageable risks and which are not, motivated by incentive structures, such as the Acceptable Risk Process and the Flight Readiness Review, and, crucially, also by organizational and work-group culture, rules, and norms, shaped by economic and political history. The outcome is driven by the following tension: agents have information that the principal cannot observe because they are on the scene, while the principal can only observe the outcome; but the principal makes the ultimate decision to go ahead with flight. Such tensions particularly affect young professionals who are new to the industry and therefore are especially lacking connection to those at the top who are making crucial decisions.

The human gut, once considered barren, is now known to harbour a vast community of trillions of microorganisms, collectively known as the gut microbiome. This intricate ecosystem plays a pivotal role in shaping our overall health and well-being, encompassing crucial functions such as digestion, immunity, metabolism, and mental well-being. This paper embarks on a historical and scientific journey, tracing the evolution of probiotics from their ancient origins in fermented foods to their present status as potent tools for targeted modulation of the gut environment. Probiotics, with their extensive history, encompass a wide range of interventions, from traditional fermented foods to modern supplements. They offer the potential for personalized health interventions by modulating the gut microbiome. Mechanisms of probiotic action include competitive exclusion and niche competition, which contribute to restoring microbial balance within the gut. The future of probiotics lies in precision medicine, where tailored interventions can harness their full potential. By combining probiotics with prebiotics, substances that nourish beneficial gut bacteria, we can enhance their efficacy and create a more favourable gut environment. Ongoing research aims to unlock the complete spectrum of probiotic interventions and their health benefits, paving the way for personalized probiotic therapies.This paper highlights the significance of probiotics in managing digestive ailments, boosting immunity, and influencing chronic health conditions. However, challenges related to safety and strain specificity necessitate a cautious and personalized approach to probiotic use. Considering the current state of research and acknowledging the remaining hurdles, we envision a future where personalized probiotic interventions unlock the full potential of this microbial odyssey, enhancing human health and well-being.

Layered composite structures are a commonly used, lightweight option for aerospace vehicles today. However, these structures are prone to delamination between plies as well as separation between co-cured sections such as skins and flanges. In addition, delamination can easily be induced by impact damage from events such as tool drops and hailstones. Since such delaminations are often not visible from the external surface of the structure, additional material or fasteners must be included in the design to ensure the structure will maintain the required load-carrying ability through its lifetime. However, adding extra material increases weight and reduces structural efficiency and adding fasteners and their associated holes reduces manufacturing efficiency and adds the requirement to inspect the holes since they could become crack initiation points. Alternate means to reduce delaminations could be beneficial. An alternative to these options is to build the structure with through-thickness reinforcement, such as using stitching threads, to limit delamination, increase out-of-plane strength, and provide a method to join structural elements together without fasteners. The history of through-thickness stitching as it could be applied to aerospace vehicles is described in this paper.

The Institute of Electrical and Electronic Engineers (IEEE) Future Networks International Network Generations Roadmap (INGR) Applications and Services Working Group developed a Transdisciplinary Framework that extends across end-to-end ecosystems, and caters to different stages of priorities, resources, and technologies. The Transdisciplinary Framework is sustainable, structured, flexible, adaptable, and scalable. It may be used by academic stakeholders for new research topics of interest, industry stakeholders to develop solutions for roadmap identified opportunities while minimizing negative risks, and government stakeholders for governance and policy development. The 2023 edition provides additional details on the Applications and Services Transdisciplinary Framework from Smart Cities, developed in the 1st edition, and was extended towards Smart Communities that include both urban and non-urban areas in the 2021 and 2022 editions. This edition of the IEEE INGR Application and Services roadmap chapter includes: •Transdisciplinary Framework: a dynamic sustainable framework for applications and services that extends across end-to-end ecosystems, and caters to the priorities, resources, and technologies for local urban and non-urban areas. –Ecosystem of Ecosystems: intra-ecosystem and inter-ecosystem alignments for agriculture, education, electrical power, health care, media and entertainment, public safety, transportation, and water distribution and wastewater treatment ecosystems. –Network of Networks: Future networks components (access, service delivery, operations and service management, and network extensions), use case categories and network operations enhancements. –Governance Function of Functions: strategic and governance related functions to support local area objectives that include economic development, quality of life, stakeholder attraction and retention, and policy development. •Transdisciplinary Framework Scenarios and Use Cases: climate change, smart cities, smart communities, pandemic response planning, and media and entertainment scenarios and use cases. The Applications and Services Working Group will extend the reach and depth of this framework to add new ecosystems and enhance existing ecosystems already addressed for future INGR editions.

The acoustic impedance of sound-absorbing walls can change significantly when the wall is subjected to grazing mean flow. In most cases, the wall is permeable and rigid. The shear stress on the wall then has a relatively large sound-synchronous component, which occurs when moving fluid penetrates the wall due to the sound pressure and imparts its momentum to the wall. The sound-synchronous shear stress diffuses into the fluid layer adjacent to the wall, known as the acoustic boundary layer, where it deforms the flow field. Thus, in addition to the displacement of the fluid at the wall, an additional wall-normal displacement of the fluid outside the boundary layer is generated, which causes the effective wall impedance to change. In turbulent flow, the shear stress is usually assumed to be generated by an effective viscosity and the local shear rate. Here, in contrast to previous studies, we consider that the turbulent viscosity is bound to the fluid displaced by the particle velocity through the permeable wall. Thus, the generation of turbulent shear stress must first be calculated in the coordinate system that follows the wall-normal displacement of the fluid. However, the displacement of the turbulent eddies means that the relationship between the eddies and the wall is out of equilibrium, which will be restored after some relaxation time. Then the generation of turbulent shear stress again depends on the velocity field in the wall-fixed coordinate system. Two models have been developed to qualitatively study the added displacement in non-relaxed and fully relaxed flow. The relaxation process has also been modelled and it is found that the added displacement never reaches the value predicted for fully relaxed flow, which however has been the starting point in all previous studies.

The ability to understand UAP and its impact on aviation safety relies heavily upon the quality of data that can be retrieved and analyzed from aviation-related UAP sighting reports. Current guidance directs the aviation community to report UAP incidents to a civilian reporting center. The current multitude of (non-aviation-specific) civilian reporting centers is an obstacle to achieving this understanding of UAP. This paper proposes that a viable solution is the establishment of a single, national (or potentially international) reporting center for all aviation-related UAP incidents. An optimal platform to host this reporting center is the NASA Aviation Safety Reporting System (ASRS).
