k-Domination Vertex Connectivity in Internet of Things Networks
The Internet of Things refers to a collection of closely connected devices that form a network through wireless or wired communication technology that work together to achieve common goals for their users. The IoT devices that are distributed in nature may cause the system to suffer from server crashes, server omissions, incorrect responses, and arbitrary errors. In this paper, we present a method of fault tolerance in IoT networks using graph theory approach to ensure the robustness of the network in case of attacks or disconnections through the concept of domination vertex connectivity in graphs. We further study this parameter in case of the Tensor product and Lexicographic product of specific graph classes, which have major implications in IoT networks.

K-Nearest Neighbor Optimization of Silver-Graphene Fiber Optic Sensor for Lung Cancer Detection
At nearly 1.8 million deaths annually, lung cancer is among the world's top causes of mortality. Cancer is curable up to a point, after which recovery is extremely challenging. Preventing cancer requires early cancer detection, which localized surface plasmon resonance (LSPR)-based sensors high sensitivity. The phenomenon known as localized surface plasmon resonance (LSPR) occurs when nanoparticles resonate with light at certain wavelengths, leading to the development of characteristics including quick reaction times, adjustable resonance, high sensitivity, and localized light-matter interaction. Since silver-graphene has qualities that make it perfect for cancer detection, it is selected as the material composition. The silver-graphene sensor is utilized for detecting CL1-5 and A549 cell lines, for which the peak of the extinction coefficients was found to be 2.7169 and 1.8592, with a sensitivity of 107 RIU. The Silver-Graphene LSPR sensor interaction with cell lines generated a novel dataset, for which K-Nearest Neighbor Regression has been chosen due to its adaptability and robustness to outliers and has been used to improve the functionality of the sensor by optimizing sensor design, improving sensor sensitivity, and reducing experimental time. With a prediction rate of 99%, KNN and the Silver-Graphene LSPR sensor are an excellent combination for early lung cancer diagnosis.

K-shell fluorescence yields of barium and lanthanum
K-shell fluorescence yields for barium and lanthanum have been measured adopting simple 2? geometrical configuration and employing a weak 57Co radioactive source. A scintillation spectrometer with an NaI(Tl) detector of dimensions 44.5mm diameter0mm thickness was employed for the detection and measurement of radiation. The results obtained are in good agreement with the best-fitted values of Hubbell et al. (1994) and also with the other experimental values, indicating that our simple method can be extended to determine fluorescence parameters of high Z materials. 2011 Elsevier Ltd. -
K-shell jump ratio and jump factor of 3d elements
Employing a simple 2?-geometrical configuration method, K-shell absorption jump ratio and jump factor have been estimated in a few 3d elements viz. Co, Ni, Cu and Zn. The target elements in the form of thin foils were excited using 32.86 keV K X-ray photons from a weak137Cs radioactive source. The emitted K X-rays were detected using a low energy HPGe X-ray detector spectrometerand the K X-ray production cross-section and K X-ray intensity ratios for all the target elements were measured. Then, using the measured data, the K-shell absorption jump factor and jump ratios have been evaluated. The obtained results agree within the experimental uncertainties with previous values reported in the literature. 2018 Author(s). -
K-Shell X-Ray Fluorescence Parameters of a Few Low Z Elements
K-shell X-ray fluorescence parameters of low Z elements cobalt, nickel, copper, and zinc have been measured employing a simple method. These elemental targets were excited by using 32.86 keV barium K X-ray photons from a weak 137Cs ?-ray source, and the emitted K-shell X-rays from these targets were detected using a low-energy high-purity germanium X-ray detector spectrometer. The results are compared with the standard theoretical, semi-empirical, fitted values and with the others experimental values. 2018, Pleiades Publishing, Inc. -
K-shell X-ray intensity ratios and vacancy transfer probabilities of Pt, Au, and Pb by a simple method
The K-shell X-ray intensity ratios, radiative and total vacancy transfer probablities of platinum, gold, and lead are measured by employing the 2?-geometrical configuration and a weak gamma source, a simple method proposed previously by our group. The targets of Pt, Au, and Pb were excited using ?-rays of weighted energy 123.6 keV from a weak 57Co source and the emitted K-shell X-rays were detected using an HPGe X-ray detector spectrometer coupled to a 16k multichannel analyzer. The measured values of these parameters are compared with the theoretical values and experimental data of other researchers, finding a good agreement. Thus, the 2?-geometrical configuration method with a weak gamma source can be alternative simple method to measure various atomic parameters in the field of X-ray spectroscopy. 2014, Pleiades Publishing, Inc. -
K? to K? X-ray intensity ratio and KL vacancy transfer probability of Mn following electron capture decay
K? and K? X-rays of Mn following electron capture (EC) decay of55 Fe were detected using Amptek XR-100 T-CdTe X-ray detector spectrometer. Measured K? and K? X-ray intensities of Mn were used to determine the K? to K? intensity ratio and total KL total vacancy transfer probability. These values were compared with the theoretical, semiempirical, and others experimental values obtained via EC decay as well as photoionization. The X-ray intensity ratio of Mn was found to be higher by 1.5% from the relativistic Hartree-Slater theoretical value. This deviation may be attributed to the exchange interactions occurring between the 3p and 3d shell electrons as well as the recoil effect of the nucleus due to neutrino emission. 2023 The Author(s). -
K???an???am Performance: K???a Devotion, Ritual Ecology, and Colonial Transformation in South India
This paper critically explores K???an???am, a Sanskrit ritual dance-theater tradition from Kerala, as a product of socio-political and religious transformations in early modern South India. Conceived in the mid-17th century by the Zamorin King M?nav?da, author of the Sanskrit text K???ag?ti, K???an???am was both a devotional offering to Lord K???a and a strategic expression of ritual sovereignty. Rooted in K???a bhakti (devotion), the tradition reflects how religious performance was mobilized to assert political legitimacy, particularly amid rivalry with regional powers such as Travancore. The Guruvayur Sri Krishna Temple, situated in the Malabar region of northern Kerala and central to the performance of K???an???am, emerged as a vital sacred space where royal patronage, ritual authority, and caste hierarchy intersected. The performances exclusivity restricted to Hindu audiences within temple premises reinforced patterns of spatial control and caste-based exclusion. Institutional support codified the tradition, sustaining it across generations within a narrow sociocultural framework. With the decline of Zamorin rule and the onset of colonialism, K???an???am faced structural disruptions. Colonial interventions in temple administration, landholding, and religious patronage weakened its ritual foundations. Guruvayurs transformation into a public devotional center reflected wider shifts in ritual ecology and sacred geography under colonial modernity. In both the colonial and postcolonial periods, K???an???am struggled to survive, nearly facing extinction before its revival under the Guruvayur temples custodianship. By examining K???a devotion, royal ambition, caste dynamics, and colonial transformation, this paper offers a critical lens on Keralas evolving religious and cultural landscapes. 2025 by the authors. -

Kakkot List- An Improved Variant of Skip List
Kakkot list is a new data structure used for quick searching in a well ordered sequence of list like Skip list. This ordered sequence of list is created using linked list data structure and the maximum number of levels here will be limited to log n in all input behavioral cases. The maximum number of items in each level is halved to that of previous levels and thus guarantees a fast searching in a list. The basic difference between Kakkot list and Skip list lies in the creation of levels and decision of when an item has to be included in the higher levels. In skip list the levels are created and items are added to each level during the insertion of an item where as in Kakkot list this will be done at the time of searching an item. This modification have made drastic impact in searching time complexity in the Kakkot list. Another issue in Skip list is that it is not cache friendly and does not optimize locality of reference wherein this problem is also addressed in Kakkot List. 2020 IEEE. -

Kannada script recognitions from scanned book cover images
Text extraction from the images plays a vital role in providing valuable information. Text extraction from images is still a challenging area specially extracting text from regional scripts of India like Kannada, Malayalam etc. Most of the times the images contain complex background then the cropping of text becomes even more challenging for extracting features. The input image is a scanned document images of Kannada book cover which is scanned with flatbed scanner of 400dpi resolution. The data sets are created by dividing the original images into number of varied size of blocks. Both spatial and frequency features are extracted for classifying images. This paper aims at recognizing the scanned images block which contains text or not by using multiple feature approach. The classification is analysed using Multilayer perceptron, Kstar and KNN. Experiments are performed on different sets of scanned documents of text cover images. Compare to all the classifiers KNN has given the encouraging results. Research India Publications. -
Kannada translation and validation of Wellman and Liu's theory of mind scale and children's social understanding scale in preschoolers
Background: Assessing theory of mind (ToM) in children is crucial for understanding social cognition. Wellman and Liu's ToM scale and the Children's Social Understanding Scale (CSUS) have been used to study ToM in children but are not available in the local language. Aim: This study aims to translate both scales into Kannada and validate them in preschool children. Methods: Following the rigorous WHO protocol, we meticulously translated and back-translated Wellman and Liu's ToM and CSUS into Kannada with the help of bilingual experts. Validation involved administering both scales to 118 preschool children aged 3 to 6 years from diverse urban and rural backgrounds in a cross-sectional study, ensuring the scales' applicability across different settings. Results: The Cronbach's alpha values for Wellman and Liu's ToM and the CSUS were 0.769 (95% CI 0.698 to 0.828) and 0.983 (95% CI 0.978 to 0.987), respectively, indicating high internal consistency. The test-retest reliability for Wellman and Liu's ToM scale domains ranged from 0.74 to 0.95, and for the CSUS, it was 0.99, demonstrating good reliability. Pearson's correlation between the domains of two scales ranged from 0.32 to 0.69, suggesting a moderate relationship. Conclusion: Our study findings demonstrate that Kannada translations of Wellman and Liu's ToM and CSUS have good internal consistency, test-retest reliability, and construct validity. These tools will be valuable for understanding social cognition in preschool children. 2024 Indian Journal of Psychiatry. -
Kashmir and Conflict: Objectivity and Balance in News Sourcing
Journalistic balance and objectivity have been critical concepts of scholarly debate. While balance traditionally meant giving equal space to opposing views, newer models of impartiality aim to represent a broader range of perspectives. Using a quantitative content analysis, this chapter analyses news published in the two leading English dailies, Rising Kashmir from Kashmir and Daily Excelsior from Jammu of the Indian Union Territory of Jammu and Kashmir from 1 to 31 October 2022. As many as 62 newspaper editions comprising 987 pages of broadsheets are examined and conflict-related news articles are sampled for analysis. A manual analysis is used to analyse the conflict news articles and identify the sources quoted in them. Study findings indicate the dominance of elite political sources in the news reports. Drawing from seminal studies in journalistic sociology, such as Gans Deciding Whats News, this chapter discusses the implications of the high prevalence of elite voices, comprising political, social and economic. 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG. -

Keggin-Type H5PMo10V2O40Intercalated MgAl-LDH: Structural Integrity and Bifunctional Electrocatalytic Activity
The development of earth-abundant electrocatalysts is central to sustainable water electrolysis, yet many systems are limited by poor electronic conductivity and inadequate durability. In particular, the high solubility of discrete polyoxometalates (POMs) clusters hinders their direct deployment as stable heterogeneous electrocatalysts. Here, a Keggin-type H5PMo10V2O40 POM is intercalated into MgAl layered double hydroxide (MgAl-LDH) by a formamide-assisted exfoliation-reassembly strategy to afford a POM@MgAl-LDH hybrid. Structural characterization confirms quantitative ion exchange of POM anions into the LDH galleries and an increase of the basal spacing to 9.210.5 Density functional theory calculations indicate thermodynamically favorable intercalation (?E ? ?2.3 eV per formula unit) and predict an equilibrium interlayer distance that matches the experiment. The hybrid exhibits a BET surface area of 50.6 m2 g1 and hierarchical porosity. In 1.0 M KOH, POM@MgAl-LDH functions as a bifunctional electrocatalyst, affording hydrogen and oxygen evolution overpotentials of 215 and 411 mV at 10 mA cm2, respectively, with ?97% current retention over 12 h of electrolysis. These results suggest that spatial confinement of redox-active POM clusters within an earth-abundant MgAl-LDH host reduces POM loss into solution and improves the electrocatalytic response of LDH framework, offering a practical route to nonprecious-metal bifunctional electrocatalysts for alkaline water splitting. 2026 American Chemical Society -
Kerala Development and the Attapadi Adivasi
The development experience of the state of Kerala in southwest India is based generally on democratic principles of equality and popular participation. This article focuses on the lives of the Adivasi1 people of Attapadi in the Palakkad district of Kerala. It argues that the state of Kerala largely treats the Adivasis as secondary citizens and ignores their right to be socially and economically empowered. The state of Kerala takes pride in its positive ranking on human development and social progress indexes but has not done enough to stop Adivasi infants from dying of malnutrition, and Adivasis demands for land rights have been disregarded. As a result, they are forced to live obscure lives in poverty and generally unable to influence their sociopolitical sphere. 2023 The Author(s). -
