This study evaluated the biocontrol potential of Trichoderma viride and Aspergillus niger against Lasiodiplodia theobromae, the causal agent of inflorescence blight disease in cashew. In dual culture tests, both T. viride and A. niger significantly inhibited the growth of L. theobromae compared to the control. A. niger exhibited the highest inhibition, reducing pathogen growth by 74.7% in one technique. In a second technique, T. viride showed the strongest antagonism, limiting pathogen growth by 90.5%. The study suggests that both tested biocontrol agents, particularly A. niger, have potential for managing inflorescence

Body in mind

Alebmj

The psychiatrist José Miguel Gaona has published a book analyzing how the power of the mind can influence physical health and the time of death. He observed people who appeared healthy dying suddenly due to stress, and patients with AIDS who entered depressive states after their diagnosis and then died. Gaona also notes that many people who have near-death experiences report seeing tunnels, lights, or deceased relatives, suggesting the mind can have experiences just before death. He concludes these near-death experiences follow complex patterns and symbolism rather than being random neurological events.

De-virtualizing virtual Function Calls using various Type Analysis Technique...

IOSR Journals

This document discusses techniques for optimizing virtual function calls in object-oriented programming languages. Virtual function calls are indirect calls that involve lookup through a virtual function table (VFT) at runtime, which has performance overhead compared to direct calls. Various static analysis techniques like Class Hierarchy Analysis (CHA) and Rapid Type Analysis (RTA) aim to resolve some virtual calls by determining the possible target types and replacing indirect calls with direct calls if a single target is possible. CHA uses the class hierarchy and declared types to determine possible target types, while RTA also considers instantiated types in the program to further reduce possible targets. The document analyzes examples to demonstrate how CHA and RTA can optimize some virtual calls.

This document discusses selective jamming attacks in wireless networks and methods to prevent them. It begins by introducing the open nature of wireless networks leaves them vulnerable to jamming attacks. It then discusses different types of jamming attacks and notes that selective jamming, which targets specific important packets, is more effective than continuous jamming. The document proposes using cryptographic techniques like commitment schemes and puzzles combined with physical layer parameters to prevent real-time packet classification and selective jamming. It reviews related work on jamming attacks and defenses. Finally, it outlines the problem statement, system model, and the contribution of using symmetric encryption and resisting brute force block encryption attacks to reduce jamming through packet hiding.

Classification By Clustering Based On Adjusted Cluster

IOSR Journals

This document summarizes a research paper that proposes a new technique called "Classification by Clustering" (CbC) to define decision trees based on cluster analysis. The technique is tested on two large HR datasets. CbC involves running a clustering algorithm on the dataset without using the target variable, calculating the target variable distribution in each cluster, setting a threshold to classify entities, fine-tuning the results by weighting important attributes, and testing the results on new data. The paper finds that CbC can provide meaningful decision rules even when conventional decision trees fail to do so, and in some cases CbC performs better. A new evaluation measure called Weighted Group Score is also introduced to assess models when conventional measures cannot be used

A Novel PSNR-B Approach for Evaluating the Quality of De-blocked Images

IOSR Journals

This document discusses evaluating the quality of deblocked images using different quality assessment metrics. It proposes a new metric called PSNR-B that includes a blocking effect factor in PSNR calculations. The document compares PSNR-B to PSNR and SSIM metrics. It studies the effect of quantization step size on measured image quality and analyzes how deblocking algorithms like lowpass filtering can reduce blocking artifacts but also introduce new distortions. Simulation results show PSNR-B correlates better than PSNR with subjective quality judgments of deblocked images.

A New Theoretical Approach to Location Based Power Aware Routing

IOSR Journals

This document proposes a new theoretical approach to location based power aware routing in mobile ad hoc networks (MANETs). It aims to extend the network lifetime by improving power utilization during routing. The approach uses nodes' location information, remaining battery power, and bandwidth status to assign link stability and select routes with lower "uptime values" and minimum bandwidth over time. This is hypothesized to better utilize nodes' power sources and bandwidth. The document outlines calculating a root up time factor for each node based on its power backup and required power, and only using nodes with maximum backup. It concludes future work will design and validate a new protocol based on this approach.

SmartData Webinar: Applying Neocortical Research to Streaming Analytics

DATAVERSITY

We are witnessing an explosion of sensors and machine generated data. Every server, every building, and every device generates a continuous stream of information that is ever changing and potentially valuable. The existing big data paradigm requires storing data for batch analysis, and extensive modeling by a human expert, prior to deployment. This is incredibly inefficient and cannot scale. In this webinar, Ahmad will describe a new paradigm for streaming data algorithms, based on recent neuroscience findings and on the computational properties of the neocortex. These systems are highly automated, adapt to changing statistics, and naturally deal with temporal data streams. Many of the core ideas have been implemented in the open source project NuPIC, and validated in commercial anomaly detection and predictive maintenance applications. Given the massive increase in the number of data sources, a general-purpose automated approach is the only scalable way to effectively analyze and act on continuously streaming information.

Focused Exploration of Geospatial Context on Linked Open Data

Thomas Gottron

Talk at IESD 2014 workshop in Riva del Garda (at ISWC). Abstract The Linked Open Data cloud provides a wide range of different types of information which are interlinked and connected. When a user or application is interested in specific types of information under time constraints it is best to ex- plore this vast knowledge network in a focused and directed way. In this paper we address the novel task of focused exploration of Linked Open Data for geospatial resources, helping journalists in real-time during breaking news stories to find contextual geospatial information related to geoparsed content. After formalising the task of focused exploration, we present and evaluate five approaches based on three different paradigms. Our results on a dataset with 425,338 entities show that focused exploration on the Linked Data cloud is feasible and can be implemented at very high levels of accuracy of more than 98%.

Leveraging the Web of Data: Managing, Analysing and Making Use of Linked Open...

Thomas Gottron

The intensive growth of the Linked Open Data (LOD) Cloud has spawned a web of data where a multitude of data sources provides huge amounts of valuable information across different domains. Nowadays, when accessing and using Linked Data more and more often the challenging question is not so much whether there is relevant data available, but rather where it can be found, how it is structured and to make best use of it. I this lecture I will start with giving a brief introduction to the concepts underlying LOD. Then I will focus on three aspects of current research: (1) Managing Linked Data. Index structures play an important role for making use of the information in LOD cloud. I will give an overview of indexing approaches, present algorithms and discuss the ideas behind the index structures. (2) Analysing Linked Data. I will present methods for analysing various aspects of LOD. From an information theoretic analysis for measuring structural redundancy, over formal concept analysis for identifying alternative declarative descriptions to a dynamics analysis for capturing the evolution of Linked Data sources. (3) Making Use of Linked Data. Finally I will give a brief overview and outlook on where the presented techniques and approaches are of practical relevance in applications.

Thomas Gottron

The document presents a method to analyze the redundancy of schema information on the Linked Open Data cloud. It examines the entropy and conditional entropy of type and property distributions across several LOD datasets. The results show that properties provide more informative schema information than types, and indicate types better than types indicate properties. There is generally high redundancy between types and properties, ranging from 63-88% on the analyzed segments of the LOD cloud. Future work could analyze schema information at the data provider level and over time.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...

AbdullaAlAsif1

The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Applied Science: Thermodynamics, Laws & Methodology.pdf

University of Hertfordshire

When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best. Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level. Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions. Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability. Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields. I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating). I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Immersive Learning That Works: Research Grounding and Paths Forward

Leonel Morgado

We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...

Sérgio Sacani

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions among stars. Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars. The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun. Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically, the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec. Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation were carried out using the ACIS-Extract software. Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a photon flux threshold of approximately 2 × 10−8 photons cm−2 s −1 . The X-ray sources exhibit a highly concentrated spatial distribution, with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Phenomics assisted breeding in crop improvement

IshaGoswami9

As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus, high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology, and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

The binding of cosmological structures by massless topological defects

Sérgio Sacani

Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is mitigated, at least in part.

The debris of the ‘last major merger’ is dynamically young

Sérgio Sacani

The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the ‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space, because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago. We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data 1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’ did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within the last few Gyr, consistent with the body of work surrounding the VRM.
