Peer-to-Peer Communication Trade-Offs for Smart Grid Applications: Preprint
Peer-to-peer energy management systems for smart grids require developers to consider the trade-offs between the amount of communication traffic generated and the quality and speed of convergence of the control algorithms that are deployed. Employing a fully connected communication causes messages to scale exponentially with the number of nodes, while using a sparse connectivity causes less information dissemination leading to degradation of the algorithm performance. The best communication topology for a particular application lies somewhere in between and often requires empirical evaluation by application designers. Existing methods do not put focus on the needs for smart grid applications, which is information dissemination throughout the network and they do not provide a flexible solution for application developers to prototype and deploy different topologies without modifying the application code. This paper introduces a configurable virtual communication topology framework TopLinkMgr, allowing users to specify any chosen communication topology and deploy peer-to-peer applications using it. It also introduces a self-adaptive, fault-tolerant topology management algorithm, Bounded Path Dissemination that can ensure the dissemination of information to all peers within a specified threshold for a sparsely connected topology. Experiments show that the algorithm improves on convergence speed and accuracy over state-of-the-art methods and is also robust against node failures. The results indicate the possibility of achieving a close-to optimal convergence without overloading the network allowing the realization of peer-to-peer control platforms covering larger and more complex power systems.

Interconnected Risks in Electricity Systems: Understanding Research Challenges, Needs, and Partnerships
The U.S. federal government has a potential role in mitigating the most poorly addressed risks across electricity markets and interdependent systems. Electricity system risks stem from extreme acute shocks (e.g., cyberattacks, extreme weather, and supply chain disruptions) and chronic stressors (e.g., global economic competition, uncertainties surrounding emerging technologies, climate change, and related conflicts). These acute shocks and chronic stressors can result in dire consequences for society, underscoring the need for better information for decision makers in both public and private sectors. Best practices and a shared understanding of risk management and risk quantification must be rapidly developed and disseminated. Informed by a quantitative treatment of risk to electrical infrastructure and interdependent systems, decision makers can more prudently and efficiently prioritize mitigation initiatives to maximize benefits to government, businesses, and the public.
US Woody Crop Yield Potential Database Documentation with Referenced Yield Summary Tables
A woody crop yield potential (WCYP) database was created containing yield results with as much associated information as was available concerning the sites, soils, and experimental treatments. The database summarizes a very broad set of old and new standing biomass data from plantation-grown hardwoods and softwoods established under a wide range of conditions across the United States and Canada. The WCYP database, together with this document, is being published to disseminate information on what is available in the literature with respect to yield evaluations and to inform people that not all yield data in the open literature are suitable for evaluation of “potential” regional yields. It has also been presented with the hope that much more information will be collected and added to the WCYP database. The current set of data in the WCYP database is derived from 41 unique reference sources describing 79 experiments in the United States or southern Canada with a total of 473 different treatments. The database contains several worksheets. The worksheet that reports the complete yield curves contains roughly 1,660 rows of data and 81 columns of parameters reporting yields and associated treatment factors. Separate worksheets, linked by the source publication author and year, describe the sites and soils associated with each experiment; another separate worksheet assembles only the final yields deemed appropriate for yield potential analysis. There are additional worksheets with conversion factors relevant to the database and notes pertaining to decisions made regarding organization of the data. This technical manuscript describes how the information was assembled to create the WCYP database that is simultaneously being published on the US Department of Energy (DOE) Bioenergy Knowledge Discovery Framework website maintained by Oak Ridge National Laboratory (ORNL). A summary table with links to all worksheets in the database can be found at the web address https://www.bioenergykdf.net/WCYP .
U.S. DOE Southeast Clean Energy Application Center
Between 2010 and 2013, the U.S. Department of Energy (DOE) funded the Southeast Clean Energy Application Center (SE-CEAC), co-located at the North Carolina Solar Center at NC State University (NCSU) and at Mississippi State University. The SE-CEAC was one of eight regional CEACs established to promote and assist in transforming the market for combined heat and power (CHP), district energy (DE) and waste heat to power (WHP) throughout the U.S. CHP locates power generation at the point of demand and makes productive use of the residual thermal energy for process and space heating in factories and businesses, thus lowering the cost of meeting electricity and heat requirements and increasing energy efficiency. The overall goal of the SE-CEAC was to support end-user implementation and overall market transformation for CHP and related clean energy technologies. Five objectives were targeted to achieve the goal: 1. Market Analysis and Information Dissemination 2. Outreach and Education for Potential CHP End-users 3. Policy Support for State and Regional Stakeholders 4. Technical Assistance to Support CHP Deployment 5. Collaboration with DOE and other CEACs Throughout the project, the CEACs provided key services of education and outreach, technical assistance and market analysis in support of project objectives. These services were very effective at achieving key objectives of assisting prospective CHP end-users and informing policy makers, utilities and others about the benefits of CHP. There is a marked increase in the awareness of CHP technologies and applications as an energy resource among end-users, policymakers, utility regulators, electric utilities and natural gas utilities in the Southeast region as a result. At the end of 2013, a number of best-practice policies for CHP were applied or under consideration in various Southeast states. The SE-CEAC met its targets for providing technical assistance with over 50 analyses delivered for 412 MW of potential end-users CHP applications. Of these 50 MW of projects were under consideration at the end of 2013 based on SE-CEAC technical assistance findings.

The Effect of Luminance Pattern on Nighttime Discomfort Glare Response - CRADA 653 (Abstract)
Light Emitting Diode (LED) adoption is critical for widespread energy savings from commercial outdoor lighting systems. A complaint from the public, concerns glare from LED light fixtures especially those with exposed LED arrays. This human factor study will examine luminance uniformity of the fixture aperture to identify parameters related to this response. The outcome will inform optical design by lighting manufacturers, retaining LED energy efficiency while mitigating glare. The results may also lead to improved industry standard glare metrics for lighting. Pacific Northwest National Laboratory’s (PNNL) Lighting Science and Technology Lab in Portland OR has a purpose-built apparatus with exposed LED arrays that have been used for prior work. It can easily be adapted for use in this experiment. Interchangeable templates will allow changing patterns for the stimulus. Glare ratings from the recruited subjects will be analyzed and reported in a peer-reviewed journal for application by luminaire manufacturers for improved products. The McClung Foundation’s interest is to better understand human perception of lighting, leading to more comfortable and effective visual environments. Members of the Foundation’s Technical Review Committee will be instrumental in reviewing the experimental design, analysis, and the final report. They will also help disseminate information about the results within the lighting community.
Visualizing and analyzing 3D biomolecular structures using Mol* at RCSB.org: Influenza A H5N1 virus proteome case study
The easiest and often most useful way to work with experimentally determined or computationally predicted structures of biomolecules is by viewing their three-dimensional (3D) shapes using a molecular visualization tool. Mol* was collaboratively developed by RCSB Protein Data Bank (RCSB PDB, RCSB.org) and Protein Data Bank in Europe (PDBe, PDBe.org) as an open-source, web-based, 3D visualization software suite for examination and analyses of biostructures. It is capable of displaying atomic coordinates and related experimental data of biomolecular structures together with a variety of annotations, facilitating basic and applied research, training, education, and information dissemination. Across RCSB.org, the RCSB PDB research-focused web portal, Mol* has been implemented to support single-mouse-click atomic-level visualization of biomolecules (e.g., proteins, nucleic acids, carbohydrates) with bound cofactors, small-molecule ligands, ions, water molecules, or other macromolecules. RCSB.org Mol* can seamlessly display 3D structures from various sources, allowing structure interrogation, superimposition, and comparison. Using influenza A H5N1 virus as a topical case study of an important pathogen, we exemplify how Mol* has been embedded within various RCSB.org tools—allowing users to view polymer sequence and structure-based annotations integrated from trusted bioinformatics data resources, assess patterns and trends in groups of structures, and view structures of any size and compositional complexity. In addition to being linked to every experimentally determined biostructure and Computed Structure Model made available at RCSB.org, Standalone Mol* is freely available for visualizing any atomic-level or multi-scale biostructure at rcsb.org/3d-view.
The IR Evolution in Oncology: Tools, Treatments, and Guidelines
Early focus of interventional oncologists was developing tools and imaging guidance, performing “procedures” acting as a skillful technician without knowledge of clinical patient outcomes, beyond post-treatment image findings. Interventional oncologists must deliver “treatments” and not “procedures”, and focus on clinically relevant outcomes, provide clinical continuity of care, which means stand at multidisciplinary tumor boards, see patients in consultation before treatment and for follow-up. Interventional oncologists have fought for the same “market” with surgery in a head to head, bloody competition called red ocean strategy in marketing terms, resulting in many aborted trials. Wide adoption of interventional oncology is facing the challenge to build evidence with overall survival as endpoint in randomized trials while the benefits of a treatment on overall survival are diluted by the effects of possible/inevitable subsequent therapies. Because interventional oncology is a disruptive force in medicine achieving same results as others (surgery) using different, less invasive approaches, patients where surgery is irrelevant can be target with a blue ocean strategy (to propose treatment where there is no competition). Recently interventional oncology has been included in the ESMO guidelines for colorectal cancer with oligometastatic disease with both surgical resection, and thermal ablation classified in the same category called “local ablative treatments”. Interventional oncologists have to shape the future by publications in oncologic journal, by being active members of oncology scientific societies, and use modern public megaphone (blog, video sharing, …) to disseminate information and let society know that interventional is not a me-too product but a disruptive treatment.
Changes to virus taxonomy, the international code of virus classification and nomenclature, and the ICTV statutes ratified by the International Committee on Taxonomy of Viruses (2025)
Abstract The 56th meeting of the Executive Committee (EC) of the International Committee on Taxonomy of Viruses (ICTV) was held in Bari, Italy, in July/August, 2024, and 115 submitted taxonomy proposals were reviewed. A total of 112 were subsequently ratified by the ICTV membership. An additional 9 error correction proposals were also approved in August 2025. This article lists the taxonomy proposals that have now been incorporated into release 40 version v2 of the Master Species List ( https://ictv.global/msl ), the Virus Metadata Resource ( https://ictv.global/vmr ), and associated ICTV databases. In addition to the assignments of 1,563 new virus species, 243genera, 55 families, 11 orders, and 8 classes, there were substantial additions to higher taxonomic ranks. These include the creation of a new realm ( Singelaviria ), which is based on the recognition of a separate evolutionary origin for the hallmark capsid genes of members of the kingdom Helvetiavirae. These express capsid proteins forming a single jelly-roll fold that is structurally and evolutionarily distinct from those of members of the family Bamfordvirae , assigned to the realm Varidnaviria . Furthermore, the realm Varidnaviria underwent a major reorganization, including the addition of a new kingdom, Abadenavirae . Another notable change was the classification of the vertebrate-infecting single-stranded DNA anellovirids into a new phylum Commensaviricota (kingdom Shotokuvirae , realm Monodnaviria ). Archaeal viruses infecting the hyperthermophilic Archaeoglobi were assigned to a new phylum Calorviricota , in the kingdom Trapavirae (realm Monodnaviria ), whereas RNA viruses infecting hyperthermophilic bacteria were classified into a new phylum Artimaviricota (realm Riboviria ). In recognition of his extensive and valuable contributions to virus taxonomic developments in Study Groups and over the period of his EC membership, Stuart Siddell was honoured as a new life member of the ICTV. The ICTV has created a new strategy for disseminating information on taxonomy advances through annual open-access publication of citeable taxonomy proposal summaries from each ICTV Subcommittee. A collective total of 354 co-authors of the seven summaries were drawn from members of each Subcommittee, the EC, and a very large number of contributors from the wider virology community.
Mobile phone and my health
The interaction of the microwave radiation emitted by mobile phones with the user's body is analyzed from the International Commission on Non-Ionizing Radiation Protection (ICNIRP) recommendations perspective as a correlation between the specific absorption ratio (SAR) of the mobile phone and the call duration. The relative position of the cell phone to the user's body, the dielectric properties of the exposed body parts, the SAR value and the call duration are considered in the local body temperature rise due to the microwave heating effect. The recommended local temperature rise limit in the human body is evaluated according to standards. The aim of this study is to disseminate information to young people, especially high school students, about the microwave thermal effects on the human body, to make them aware of the environmental electromagnetic pollution and to offer them a simple method of biological self protection.
