Electrical transport and magnetoresistance studies on the magnetic moment compensated Mn2V1-xCoxZ (Z=Ga, Al; x=0, 0.25, 0.5, 0.75, 1) Heusler alloys
We report the electrical resistivity and magnetoresistance properties of arc-melted Mn2V1-xCoxZ (Z=Ga, Al; x =0, 0.25, 0.5, 0.75, 1) alloys, which possess compensated ferrimagnetic behaviour with high TC when x=0.5. Apart from metallicity, the alloys in the Ga series with x= 0, 0.75, 1 composition showed a positive to negative crossover in the magnetoresistance versus temperature curves. This crossover was absent for Mn2V0.75Co0.25Ga and the fully compensated ferrimagnet Mn2V0.5Co0.5Ga. In contrast to this, Co-substituted Mn2VAl exhibits distinctly different resistive behaviour. While the alloys Mn2VAl and Mn2CoAl exhibit metallic and semiconducting behaviour respectively, the intermediate compositions show a gradual metallic to semiconducting transition as the Co concentration increases. The compensated ferrimagnet Mn2V0.5Co0.5Al showed a mixed transport behaviour of metallic and semiconducting nature with a resistivity minimum at 140 K. In contrast to this mixed response of the arc-melted bulk sample, the Mn2V0.5Co0.5Al melt-spun ribbon shows a clear semiconducting nature throughout the temperature range, indicating that the sample preparation methods could highly influence the electrical properties of the investigated compensated ferrimagnets. 2024 Elsevier B.V. -

On the fully compensated ferrimagnetism in Mn2V1-xCoxAl (x=0, 0.25, 0.5, 0.75, 1) Heusler alloys: An ab initio and neutron diffraction study
We present a detailed ab initio investigation on the interesting Heusler alloys Mn2V1-xCoxAl (x=0,0.25,0.5,0.75,1), which exhibit fully compensated ferrimagnetism with high Curie temperature for x = 0.5. Calculations were performed by incorporating various atomic anti-site disorders, and the minimum energy structure causing the fully compensated ferrimagnetic state with high Curie temperature in Mn2V0.5Co0.5Al was identified to be L 21 with Mn-Co disorder. This L 21 phase, along with the ferrimagnetic interaction among the parallelly coupled (Mn(A)-Mn(C)) and (V-Co) pairs, gives rise to the fully compensated ferrimagnetism in the half-metallic Mn2V0.5Co0.5Al Heusler alloy. Increasing Co concentration in Mn?VAl induces a change in structure from the L 2? phase to the X ? phase. The peculiar spin gapless semiconducting behavior of Mn2CoAl was evident from the ab initio results. Ab initio results have explained the previously reported anomalies in the electrical resistivity of Mn2V1-xCoxAl. Neutron diffraction analysis has confirmed, for the first time, that Mn2V0.5Co0.5Al has a disordered L 2? structure, which agrees with the ab initio results. 2025 Elsevier B.V. -
1-Normal DRA for insertion languages
Restarting automaton is a type of regulated rewriting system, introduced as a model for analysis by reduction. It is a linguistically motivated method for checking the correctness of a sentence. In this paper, we introduce a new definition of normal restarting automaton in which only one substring is removed using the DEL operation in a cycle. This DEL operation is applied to reverse the insertion operation in an insertion grammar. We use this 1-normal restarting automaton to solve the membership problem of insertion languages. Further, we introduce some interesting closure properties of 1-normal restarting automata. 2017, Springer International Publishing AG. -
Polynomial time learner for inferring subclasses of internal contextual grammars with local maximum selectors
Natural languages contain regular, context-free, and context-sensitive syntactic constructions, yet none of these classes of formal languages can be identified in the limit from positive examples. Mildly context-sensitive languages are capable to represent some context-sensitive constructions such as multiple agreement, crossed agreement, and duplication. These languages are important for natural language applications due to their expressiveness, and the fact that they are not fully context-sensitive. In this paper, we present a polynomial-time algorithm for inferring subclasses of internal contextual languages using positive examples only, namely strictly and k-uniform internal contextual languages with local maximum selectors which can contain mildly context-sensitive languages. 2017, Springer International Publishing AG. -
Polynomial time algorithm for inferring subclasses of parallel internal column contextual array languages
In [2,16] a new method of description of pictures of digitized rectangular arrays is introduced based on contextual grammars, called parallel internal contextual array grammars. In this paper, we pay our attention on parallel internal column contextual array grammars and observe that the languages generated by these grammars are not inferable from positive data only. We define two subclasses of parallel internal column contextual array languages, namely, k-uniform and strictly parallel internal column contextual languages which are incomparable and not disjoint classes and provide identification algorithms to learn these classes.

A finger print recognition using CNN Model
The fundamental goal of this research is to improve the new identification accuracy for fingerprint acknowledgment by contrasting Convolutional Neural Networks (CNN) model frameworks for biometric safety in the cloud with Conventional inception models (TIM). Accuracy was computed and compared using a CNN model and standard Inception Models (N=10). The statistical significance was calculated using SPSS. Average and standard deviation for a 95% confidence interval, 0.05% G-power cutoff. The TIM and Convolutional Neural Networks performed an autonomous T-Test on the samples. CNN is more successful (93%) than TIM (61%). Based on a significant value of 0.048 for the comparison ratio (p0.05), there is a statistically significant difference between the CNN and the TIM transformation. According to the findings, the suggested CNN model is 93% accurate on the dataset, with no rejected samples. 2023 IEEE. -
Intellectual Capital, FinTech Innovation, and Sustainable Performance: Moderating Role of Financial Literacy
In a fast-paced digital world of growing sustainability demands, organizations must utilize knowledge-based and financial resources in order to stay competitive and accountable. Even though there is increasing academic interest, the empirical evidence on how and when the major dimensions of intellectual capital (IC), human, structural, and relational capital, combine to contribute to sustainable performance (SP) remains fragmented and inconclusive. Given this, the present study empirically investigates the impact of IC, including human, structural, and relational capital, on SP. It also aims to examine the potential impact of FinTech innovation (FI) and financial literacy on IC and SP. Based on the Technology innovation theory and Resource based view, this study develops and empirically tests the proposed model that integrates intangible knowledge resources and technological capabilities to explain SP. Data were collected from 413 managers of the Indian banking industry. Structural equation modeling and Hayes Process were used to test the hypotheses. The findings exhibit that IChuman, structural, relational capital, and financial literacyplay a significant and positive role in FI and SP. The path analysis also confirmed a significant role of FI on IC and SP. This study suggests that managers and policymakers can improve the banking performance in an eco-friendly manner by actively resorting to investments in knowledge resources and digital transformation initiatives. Accordingly, the study model offers an integrative framework showing how financial institutions can ensure SP by converging IC, FI, and FL. 2026 ERP Environment and John Wiley & Sons Ltd. -
Navigating turbulence: how economic policy uncertainty shapes tourism firms cash strategiesa global analysis
This paper investigates the strategies employed by tourism businesses to handle cash flow in the face of economic policy uncertainty. The study examines data from 1260 firms in 18 countries over a span of 15 years. The findings indicate that there is considerable variation among corporations when it comes to their use of liquidity, with the average corporation holding approximately 13.5 per cent of its total assets in liquid form. The analysis provides evidence that economic policy uncertainty has a positive and significant relationship to cash holdings in the tourism sector. These findings suggest that corporations increase their liquidity buffers in response to higher levels of policy uncertainty. Sectoral analysis also reveals that the sensitivity to policy uncertainty can vary significantly from one sub-sector to another. Ultimately, indicating varied factors that can lead to the differentiatingeffect of EPU on liquidity management of the tourism firms. 2025 Informa UK Limited, trading as Taylor & Francis Group. -
Economic policy uncertainty and corporate inventory holding: evidence from emerging economies
Purpose: This study aims to investigate how economic policy uncertainty (EPU) influences the inventory levels of 6,150 companies in ten emerging economies, specifically Chile, Brazil, China, Colombia, Hong Kong, India, Mexico, Pakistan, Russia and Singapore. Design/methodology/approach: The data used in this study is of quarterly frequency from 2004Q1 to 2020Q4 collected from the COMPUSTAT global database. To estimate the coefficients, this study has employed a two-step GMM model. Findings: We have discovered new evidence indicating a curvilinear relationship, specifically an inverted U-shaped pattern, between economic policy uncertainty (EPU) and corporate inventory holdings. These findings remain resilient when subjected to various rigorous tests. Furthermore, we observe that firms with lower financial constraints are capable of increasing their inventory holdings to a significant extent in the presence of high economic policy uncertainty (EPU) than firms facing higher financial constraints. Originality/value: Our research adds to the expanding body of literature that explores the impact of economic policy uncertainty on firm-level decision-making. We provide fresh evidence regarding the correlation between economic policy uncertainty and inventory holding, specifically focusing on emerging economies worldwide. Furthermore, we make a valuable contribution to the existing literature by examining whether the association between economic policy uncertainty and inventory holdings is influenced by the extent of financial constraints. 2025, Emerald Publishing Limited. -
Echoes of Empire: Portuguese Cultural Imperialism in Goa and Mangalore from the 15th to 18th Centuries
The Portuguese colonization in Goa and its indirect religious influence in Mangalore from the 15th to the 18th century left behind a complex legacy of social, cultural, economic, political, and religious changes. Situated within postcolonial and neocolonial studies, the paper explores the mechanisms of Portuguese cultural dominance in Goa coerced religious conversion, linguistic imposition, architectural transformation, communication, and educational control contrasted with more indirect cultural and religious influence in Mangalore, and, as a result, the impact of cultural imperialism and cultural transformation. The study contextualises the enduring effects of these colonial processes by using the theoretical frameworks of Anal Quijano concept of Coloniality of Power, Johan Galtungs Centre-Periphery Model, Edward Saids Orientalism, and Herbert Schillers Communication Imperialism. The paper highlights local resistance and cultural hybridization, and reveals a complex negotiation between imposition and adaptation. The study emphasizes the legacy of Portuguese imperialism within a broader perspective of global power structures and how it has shaped the modern neocolonial frameworks. The findings contribute to discussions on cultural imperialism by illustrating how historical hegemonic practices persist through language policies, architectural preservation, and religious traditions. The paper also touches upon the regions postcolonial identity formation through Goas Lusophone heritage and Mangalores distinct religious evolution. This analysis demonstrates how past mechanisms of control continue to influence the contemporary global and regional dynamics, reinforcing cultural hegemony through modern neocolonialism. 2024 selection and editorial matter, Dr. L.

Positive side effects of the Covid-19 pandemic on environmental sustainability: evidence from the quadrilateral security dialogue countries
Purpose: The eruption of coronavirus disease 2019 (COVID-19) has pointedly subdued global economic growth and producing significant impact on environment. As a medicine or a treatment is yet available at mass level, social distancing and lockdown is expected the key way to avert it. Some outcome advocates that lockdown strategies considered to reduce air pollution by curtailing the carbon emission. Current investigation strives to affirm the impact of lockdown and social distancing policy due to covid-19 outbreak on environmental pollution in the QUAD nations. Design/methodology/approach: To calibrate the social movement of public, six indicators such residential mobility, transit mobility, workplace mobility, grocery and pharmacy mobility, retail and recreation mobility and park mobility have been deliberated. The data of human mobility have been gathered from the Google mobility database. To achieve the relevant objectives, current pragmatic analysis exerts a panel autoregressive distributed lag model (ARDL)-based framework using the pooled mean-group (PMG) estimator, proposed by Pesaran and Shin (1999), Pesaran and Smith (1995). Findings: The outcome reveals that in the long-run public mobility change significantly impact the pollutants such as PM2.5 and nitrogen dioxide; however, it does not lead to any changes on ozone level. As per as short run outcome is concerned, the consequence unearths country wise heterogeneous impact of different indicators of public mobility on the air pollution. Research limitations/implications: The ultimate inferences of the above findings have been made merely on the basis of examination of QUAD economies; however, comprehensive studies can be performed by considering modern economies simultaneously. Additionally, finding could be constraint in terms of data; for instance, Google data used may not suitably signify real public mobility changes. Originality/value: A considerable amount of investigation explores the impact of covid-19 on environmental consequences by taking carbon emission as a relevant indicator of environmental pollution. Hence, the present pragmatic investigation attempts to advance the present discernment of the above subject in two inventive ways. Primarily, by investigating other components of environmental pollution such as nitrogen dioxide, PM2.5 and ozone, to reveal the impact of covid-19 outbreak on environmental pollution, as disregarded by the all preceding studies. Additionally, it makes a methodological contribution before integrating supplementary variables accompanying with ecological air pollution. Finally, the current research article provides an alternative and creative approach of modeling the impact of public mobility on environmental sustainability. 2021, Emerald Publishing Limited. -
Tracking the transmission channels of fiscal deficit and food inflation linkages: A structural var approach
This empirical analysis aspired to unearth the transmission channels of fiscal deficit and food inflation linkages in the Indian perspective by reasonably exerting the data for 1991 to 2017. The precise results of structural vector autoregressive (SVAR) analysis proffered that there were three different mechanisms of transmission such as consumption, general inflation, and import channels that led to food inflation in response to the high fiscal deficit. The first channel revealed that government deficit spending had a positive impact on income which further led to food inflation through surging the household consumption expenditure. It was concluded that fiscal deficit passed through general inflation finally leading to a food price surge in the economy and seemed to work as cost-push inflation for the food and agricultural industry. The outcome also revealed that the impact of fiscal deficit passed to food inflation through external linkages such as import and export. 2020 The Society of Economics and Development, except certain content provided by third parties. -
Foreign Exchange, Gold, and Real Estate Markets in India: An Analysis of Return Volatility and Transmission
This empirical analysis endeavored to investigate the return volatility, covolatility, and the spillover impact of gold, real estate, and U.S. dollar in India. The generalized autoregressive conditional heteroskedasticity dynamic conditional correlation (GARCH -DCC) was used to reveal the return volatility and conditional correlation. The volatility spillover was examined by using the variance decomposition technique. The empirical outcome clearly revealed the presence of ARCH and GARCH effect on gold, realty, and U.S. dollar. Additionally, the results also manifested that the returns of these variables were not moving away from their means in the long run. On the other hand, the consequences of volatility spillover reported that real estate was the most dominating among all markets. This is so because returns on real estate had a significant contribution to the return volatility of the other markets. Finally, it was also found that return volatility of U.S. dollar was most affected as it was the net receiver of volatility, while return volatility of gold seemed to be neutral in the Indian financial market. -
The Himalayan Ecosystem and Development Paradigm: A Sustainability Perspective
The Himalaya is physically and biologically very complex and diverse. It is one of the youngest and loftiest of the mountain systems of the world. It is a biodiversity rich area having a distinctive climatic impact on lives of people in Asia. Major rivers of the region originate from the Himalayan Mountains providing the source of water for a large mass of population. Himalaya is a house to many crops of the world, natural wealth as well as indigenous societies and knowledge system. It is a rich repository of plant and animal wealth providing a source of livelihood to millions of people in the Asian region. Its significance lies in the fact that it has been recognised as among the 34 global biodiversity hotspots. Due to anthropogenic activitiesdriven by the economic development modellike mining, road construction, dam construction, tourism, infrastructure development et al. and climate change there has been wide spread damage to fragile Himalayan ecosystem. The consequences of such developmental activities has far reaching consequences on the future of Himalayan ecosystem altering the course of nature and impacting human lives and societies depending on Himalaya and hence unsustainable for the earth. It is predicted that the anthropogenic activities in and around Himalayas shall have significant consequences regionally and globally raising questions about natural resources, ecology, sustainability, loss of habitat by species, human rights, livelihood of people in the region. The present model of development solely premised on the anthropocentricism has caused enormous harm to Himalayan ecology. It has ignored the traditional conservation model adopted by traditional inhabitants bringing great destruction to the Himalaya which has global implications. In the light of the above this chapter will discuss the consequences of anthropogenic activities on the Himalayan ecosystem. Moreover, it will explore the sustainability of anthropogenic activities and how that can be helpful to the planet. Moreover, it will offer few suggestions for the improvement of the Himalayan ecosystem which will be advantageous to the present as well as future generations.

Food Security and Global Institutions: A Global Justice Perspective
Food security refers to a condition where all people have physical and economic access, at all times, to sufficient, safe and nutritious food that meets their needs and food preferences to lead an active and healthy life. Universal Declaration of Human Rights, 1948 (UDHR) declares the right to food as a basic human rights. International Covenant on Economic, Social and Cultural Rights, 1976 (ICESR) explicitly recognises the right of everyone to food and mandates all state parties for its realization; also it recognizes everyones right to be free from hunger as a fundamental right. Further, it instructs the state parties to ensure equitable distribution of world food supplies to achieve the right of everyone to be free from hunger. Rome Declaration on World Food Security, 1996 reaffirmed the right of everyone to access to safe and nutritious food compatible with right to adequate food and also right to be free from hunger. United Nations Millennium Declaration set the goal for fighting hunger and resolved to reduce the proportion of people suffering from hunger to half by 2015, then Sustainable Development Goals were floated, inter alia, to end extreme poverty and achieve the target of zero hunger and food security by 2030. Regardless of its being a universal human rights, food security scenario across the globe is far from satisfactory and fair. Post COVID 19 scenario has seen a surge in undernourishment and food insecurity. According to The State of Food Security and Nutrition in the World, 2022, 3.1 billion people across the globe are unable to afford a healthy diet. At this juncture we are living in a deeply connected and globalized world run not by national institutions but by global institutions. The role of global institutions assume significance in a globalized world. Justice demands that policy planning and legal framework on food security should be fair and equitable; they should be based on the idea of entitlement and obligation. To achieve the goal of zero hunger and food security, what is required is an equitable and unified global governance approach premised upon the idea of global justice which shall fix obligations on global institutions. This chapter aims at examining the issue of food security from a global justice perspective and how it can be sustainably achieved. It will explain the concept of global justice and obligations of global institutions by relying upon few legal and political theories. Further, the chapter will explain the human rights perspective of the food security and the challenges involved with it.

Assessing Climate Change through Artificial Intelligence An Ethico-Legal Study
IPCC (The Intergovernmental Panel on climate change) [1], in the 6th Assessment Report released in 2022, reports that the net anthropogenic GHGs (greenhouse gases) continued to rise during the period 2010-19. It shows that GHG emission in the last decade is the highest in human history. According to the World Inequality Report, 2022, carbon dioxide concentration level in the atmosphere across the globe is the highest in millions of years. Consistent rise in the global emission level leading to alarming rise in atmospheric temperature has been a cause of concern for mankind. Rising atmospheric temperature leading to climate change has severely affected weather patterns; led to melting of glaciers; caused natural disaster and extinction of species, and severely impacted the ground water table. It has put the human race at a crossroads and thrown open an existential question for the world. Attempts have been made, both international and national, to reverse the impact of the rising scenario concerning climate change but have yet to be successful. The technological revolutions arising in recent times, especially in the domain of Artificial Intelligence (AI), offer hope to give a new shape to human civilization. With the aid of human intelligence, AI can perform assessment and predictive work as well which may help in mitigating the effect of adversely affecting climate change and help improve the environment. As per UNESCO (United Nations Educational, Scientific and Cultural Organisation), AI can perform assessment and prediction of climate change, which may assist in the protection of the environment. The Council identifies three priority areas relating to use of AI which includes improved understanding and predictions of climate change and geohazards [2]. This chapter aims at exploring the contribution of AI in assessing the behavioral pattern of climate change and the ethico-legal challenges involved therein. 2024 Sachi Nandan Mohanty, Preethi Nanjundan and Tejaswini Kar. -
Return volatility transmission among Asian stock exchanges: Evidence from a heterogeneous market outlook
. This pragmatic research strives to reveal the return volatility transmission throughout Asian stock exchanges, by employing variance decomposition technique of Vector autoregressive (VAR) based framework. Additionally, the current examination exerts a Granger causality approach to detect short-term cause and effect among the stock exchanges. The consequence of volatility spill-over exhibits the dominancy of Indian, Chinese and Japanese exchanges in terms of net volatility transmitter. Further, it is found that Korean, Thai, and Malaysian stock exchanges seem to be net receiver of volatility in Asia. Additionally, the outcome of current investigation reveals neutrality of Bangladeshi and Pakistani stock exchange, as the returns volatility of these stock exchange are not influenced by any other Asian stock exchanges. Furthermore, the result of Granger causality analysis signifies the existence of unidirectional causality among the Asian stock exchanges. In terms of policy implication, it is imperative for investors and policymakers to closely monitor the behaviour of the Japanese stock exchange, as it plays a significant role as a net transmitter of volatility to other stock exchanges in Asia. By keeping a vigilant eye on the Japanese stock exchange, investors can better assess and manage potential risks and opportunities in the region. 2023 IOS Press. All rights reserved.
