African Swine Fever (ASF) virus genomics and diagnosticsILRI
This document summarizes activities related to analyzing the genetics of the African Swine Fever virus (ASFV) in Kenya. It discusses sequencing the whole ASFV genome to analyze diversity and origins of outbreaks. Genotyping using three genetic markers finds that recent Kenyan outbreaks involve genotype IX, the same genotype present in Uganda. While whole genome sequencing and genetic analysis can inform vaccine development and tracing outbreaks, developing low-cost, rapid field diagnostics remains a priority for controlling ASF. Surveillance of pigs in coastal Kenya may also be needed to prevent the spread of genotype IX globally.

Background
Influenza A viruses are medically significant pathogens responsible for higher mortality and morbidity throughout the world. Swine influenza is known to be caused by influenza A subtypes H1N1, H1N2, and H3N2, which are highly contagious, and belongs to the family Orthomyxoviridae. Efficient and accurate diagnosis of influenza A in individuals is critical for monitoring of a constantly evolving pandemic. A rapid result is important, because timely treatment can reduce disease severity and duration. Rapid antigen tests were among the first-line diagnostic tools for the detection of pandemic H1N1 (2009) virus infection during the initial outbreak. Current study focuses on the significant approach of the usage of molecular method utilizing real-time PCR for the detection of type A influenza virus (H1N1 subtype) in humans.
Methods
A total of 2000 mixed nasal/throat swab specimens collected in commercial viral transport from Apollo hospitals, Hyderabad were submitted to Institute of Preventive Medicine for molecular testing by reverse transcriptase polymerase chain reaction (RT-PCR) from 2009 to 2015 from its affiliated primary care clinics.
Results
Among the 2000 samples collected, 700 samples were positive for Human Inf A, swine Inf A, and Swine Inf H1 (fourth table in the article). One thousand two hundred samples were negative for Human Inf A, swine Inf A, and Swine Inf H1, and 100 samples were positive for Influenza A only.
Conclusion
The molecular testing of H1N1 patients helped the clinicians in timely diagnosis and treatment of these patients during the pandemic surveillance. The RT-PCR test has higher sensitivity and specificity; hence it is considered to be the best tool to use during the pandemic surveillance, as compared to the any other commercial antigen-based tests, which show a variable performance, with the sensitivities of tests from different manufacturers ranging from 9 to 77%.
This study summarizes the first report and characterization of Cowpea mild mottle virus (CPMMV) infecting groundnuts in western Kenya. Surveys found the virus widespread across agro-ecological zones, with high incidence levels on farms. Most farmers obtained seeds from local markets or recycled seeds, likely contributing to the virus's spread. Testing confirmed CPMMV presence in some samples. Inoculated indicator plants developed varied symptoms and tested positive for the virus, suggesting it threatens other major legumes. This establishes CPMMV as a serious threat to legume production in western Kenya.
Epidemiology of African Swine Fever: A prerequisite to controlILRI
This document outlines the objectives and progress of a project studying African swine fever (ASF) in East Africa. The project aims to 1) genotype and sequence ASF virus genomes, 2) evaluate rapid diagnosis methods, 3) understand ASF epidemiology in the field, 4) assess the livelihood impact of ASF, 5) identify biosecurity measures, and 6) understand social networks related to ASF transmission. To date, the project has genotyped and sequenced viruses, trained researchers in rapid diagnosis, conducted field studies to examine virus prevalence and transmission pathways, and developed surveys to analyze the economic effects of ASF on smallholder farmers.

This document summarizes a study on silencing the Elongation factor 1-alpha (EF1α) gene in Tomato yellow leaf curl virus (TYLCV)-resistant tomato plants. The objectives were to silence EF1α and observe if resistance collapsed. Results showed that after silencing EF1α in resistant plants and inoculating with TYLCV, the resistance collapsed, as seen in increased virus infection and symptoms matching susceptible plants. It was concluded that EF1α is important for TYLCV resistance. Further study of EF1α's role in the resistance gene network was recommended.
COMPLEX CIRCULATION OF FOOT-AND-MOUTH DISEASE VIRUS IN CATTLE IN NIGERIA EuFMD
The document summarizes a study on the complex epidemiology of foot-and-mouth disease (FMD) in cattle in Nigeria from 2012-2017. Genetic analysis found half of outbreaks were the O/EA-3 topotype, while other prevalent topotypes were A/Africa/G-IV, SAT1/X, and SAT2/VII. The results indicate FMD outbreaks stem from both sustained local transmission of existing strains and repeated introductions of new strains through livestock trade with neighboring countries. More research is needed to understand the role of small ruminants and wildlife in FMD transmission to support an effective vaccination program.

The document describes the development of a highly sensitive and reliable RT-PCR test for detecting cassava frogskin virus (CFSV) that infects cassava plants. The RT-PCR method was compared to the traditional grafting technique on 508 cassava accessions and was found to be more sensitive, detecting the virus in 7 accessions compared to only 4 detected by grafting. The RT-PCR method also provides results in less than a week without the need for greenhouse space. Using this method, over 99.5% of the cassava collection maintained by CIAT was determined to be free of CFSV and available for international distribution.
The document summarizes research on pleiotropic adult plant resistance (PAPR) loci in wheat. Key points:
1. CIMMYT has conducted PAPR research since the 1970s, identifying loci such as Lr34, Lr46, and Lr67 that confer resistance to multiple diseases.
2. Studies mapped additional PAPR QTL in various wheat populations and identified markers for genes like Lr46, Sr2, and Yr54 useful for marker-assisted selection.
3. Research involves fine mapping genes, identifying deletion mutants, and understanding resistance mechanisms to improve durability and pyramide genes in wheat breeding.
4. An international shuttle breeding program

Persistence of African swine fever outbreak in a farm in Kaduna, Nigeria.David Dazhia Lazarus
This document summarizes a study on the persistence of African swine fever outbreak in a farm in Kaduna State, Nigeria. The study found that five breeder houses on the farm were wiped out within a week of the outbreak. Testing of samples from the single surviving piglet confirmed the presence of African swine fever virus through serology and PCR analysis. The outbreak demonstrates that African swine fever continues to be a problem in Nigeria due to unregulated pig movements and lack of effective control strategies. Comprehensive surveillance, improved biosecurity, and government support are recommended to improve management of the disease.
This document discusses cassava production globally and proposes a Global Alliance for Cassava Improvement. It notes that cassava is produced in 105 countries across Latin America, Africa, and Asia, with Africa producing 30% of global cassava on just 3.5 million hectares. Productivity varies greatly between regions. The document proposes forming a Global Alliance to address issues like increasing cassava productivity and yields, which have risen overall but vary between countries. It presents data on increasing cassava production and yields in various countries and regions over time. The Alliance would work to improve cassava through initiatives like addressing viral diseases, climate change impacts, breeding programs, and increasing capacity in producer countries.

Clean planting material and surveillance are important to control diseases like cassava mosaic and brown streak viruses.
Diversity of plant parasitic nematodes associated with common beans (Phaseolu...Innspub Net
Common beans (Phaseolus vulgaris L.) are the most important legume staple food in Kenya coming second to maize. In Central Highlands of Kenya, the 0.4-0.5ton ha-1 output is below the genetic yield potential of 1.5-2ton ha-1 partly due pests and diseases. Plant parasitic nematodes (PPN) have been reported to cause yield losses of up to 60% on beans. Though bean production is important in the Central highlands of Kenya, information on PPN associated with the beans in the region is lacking. This study was therefore undertaken to establish the diversity of PPN associated with common beans and to assess the root knot nematode damage on beans in the region. The study covered 50 farms (32 in Kirinyaga and 18 in Embu Counties) distributed in eight localities namely Kibirigwi (L1), Makutano (L2), Kagio (L3), Mwea (L4) and Kutus (L5) in Kirinyaga County and Nembure (L6), Manyatta (L7) and Runyenjes (L8) in Embu County and covering three Agro Ecological Zones (AEZs); UM2 (L1, L2, L3 & L4), UM3 (L5, L7 & L8) and UM4 (L6) AEZs. Manyatta (L7) and Nembure (L6), had the highest and second highest gall indices, respectively, while Kibirigwi (L1), Makutano (L2) and Mwea (L4) had some of the lowest gall indices. The most common PPN in bean roots were Meloidogyne spp. Pratylenchus spp. and Scutellonema spp. with a frequency of 94.38%, 78.25% and 59.13%, respectively. This further confirm the importance of these nematodes in bean production systems. Upper Midland 3 (UM3) AEZs and UM4 had higher nematode population densities and diversity than UM2. Disease severity and nematode composition and distribution were notably low in the irrigated areas Kibirigwi, Kagio and Mwea compared to rain-fed areas such as Makutano, Nembure and Manyatta.

The fungus spreads via spores produced on lesions that are disseminated by wind. Over 100 resistance genes have been identified in rice to provide resistance to the fungus. The genes are located on all rice chromosomes except 3 and several major gene clusters have been characterized. Breeding strategies to improve rice varieties' resistance to blast include utilizing these resistance genes.

Presented by Bright Jumbo, Lava Kumar, Dan Makumbi, George Mahuku and Yangole Luhenda at the Africa RISING East and Southern Africa Review and Planning Meeting, Malawi, 14-16 July 2015
This document summarizes a study on farmers' knowledge of integrated pest management of pink bollworm in cotton. It found that while farmers were aware of pink bollworm and its damage, they primarily used chemical controls. Key constraints reported were the high costs of pesticides and labor. The study concluded farmers would benefit from more government support like subsidies, training, and improved transport access to help address the pink bollworm threat in a sustainable manner.
Cowpea differential response to striga gesnerioides Umar Buba
This study evaluated 35 cowpea varieties for resistance to Striga gesnerioides using a pot technique method. Some breeding lines and local accessions showed complete resistance, with zero haustoria formed on roots. Striga emerged as early as 25 days after sowing. Variability existed among the varieties, with the number of Striga per pot ranging from 0 to 2.33. Varieties with some level of resistance were identified and should be tested against different Striga strains to establish their reactions and potential for use in improving resistant in susceptible varieties.

Untapped potential of genetic diversity of cassava in the great lakes region ...CIAT
1) The study analyzed genetic diversity of cassava landraces in Uganda, Rwanda, and western Kenya using SSR markers and by interviewing 287 farmers.
2) Farmers maintain a wide diversity of 3-4 cassava genotypes on their fields and have differential preferences for culinary qualities between regions.
3) Farmers' variety selection is based primarily on input traits like yield, pest resistance, and early maturity rather than culinary qualities.
This document summarizes a presentation on monitoring genetic diversity of potatoes through in-situ conservation efforts. It discusses establishing baseline data through characterization of landraces across sites in potato diversity hotspots. Levels of monitoring include documenting total diversity, relative diversity through cultivar sampling, and spatial diversity through mapping field areas of different landraces. Threats to conservation and importance of collecting associated traditional knowledge are also covered. The goal is to create a global network for long-term monitoring of diversity changes over time in major roots, tubers and bananas through collaboration between farmers, researchers and organizations.

This document summarizes two assessments conducted by Africa RISING on sustainable intensification and return on investment from 2011-2020. It finds that:
1) The total value of direct benefits to farmers was $74.6 million, while the total project cost was $15.9 million, resulting in a return on investment of 469%.
2) An assessment of progress towards sustainable intensification analyzed households by total production per hectare and compared indicators across five domains. It found that more intensified households showed improved scores in agricultural production, economics, environment, human welfare, and social indicators.
3) A focus on assessments at the woreda (district) level provided insights into differences between communities and guidance for
The document summarizes the results of a nutrition assessment study and lessons learned from it. The study aimed to identify how Africa RISING interventions contributed to household nutrition. It used a qualitative research approach with key informant interviews and focus group discussions in Ethiopia. The results showed that the interventions helped to produce and consume a more diverse and nutritious diet, generate income, and improve knowledge of food production and preparation. However, diet diversity remained low and certain nutrient-rich foods were still limited. Key lessons were that technical nutrition support needs frequent follow-ups, and engaging community leaders and husbands is important for influencing mothers' nutrition practices.
The document discusses plans for scaling assessment of Africa RISING interventions. It notes that Africa RISING's second phase focused on scaling approaches through recruiting scaling partners, training of trainers, multi-stakeholder meetings, and research backstopping. The assessment aims to document scaling practices, identify areas for increased support, and develop an exit strategy as the program period concludes. It will use ILRI's scaling framework over six months to provide a technical report and scientific paper.
This document summarizes a presentation on conducting on-farm trials at scale using crowdsourcing. It discusses the benefits and challenges of traditional on-farm trials, and proposes a solution using digital platforms and farmer participation. Farmers would receive random combinations of varieties to test on their own farms and provide rankings. Data would be collected and analyzed to provide feedback to farmers. The approach aims to increase representation while reducing costs compared to traditional on-farm trials. It outlines 10 steps for implementation, including defining varieties, designing projects, recruiting farmers, preparing packages, data collection, analysis and discussion.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.
