This paper explores the coloniality of botany and its transnational genealogy by examining critical questions about agency of representation of botanical nomenclature. We use two examples— Hortus Malabaricus in the seventeenth century, and the Traditional Knowledge Digital Library (TKDL) from the twenty-first century—as bookends to examine the legacies of colonial botany. The Hortus is a comprehensive treatise developed by Hendrik van Rheede, the governor of Dutch Malabar, with the help of local botanists, doctors, and physicians. It remains one of the most comprehensive works on the flora of Asia and the tropics. The impetus for the Hortus was the desire for a catalogue of local plants so colonists could more efficiently extract the rich botanical resources in Asia. The TKDL is a digital repository of traditional knowledge of India. The impetus was to establish prior use of herbs and medicines in India and challenge global biopiracy of traditional Indian knowledge. Both the Hortus and the TKDL are repositories that respond to colonial regimes of power—the former for more efficient colonial extraction, and the latter to thwart it. Yet both are caught up in Western norms of botanical nomenclature. Drawing on feminist, postcolonial, and transnational studies, this paper examines the two moments to explore the enduring and shifting meanings of transnational colonial regimes of power.

Purpose: Wine tourism is spreading from the "old world" wine countries to Asia. The purpose of this paper is to introduce the GLOW framework capturing the tension of homogenization and globalization of touristic experiences, the tourists' rising environmental concerns and their conflict of searching for authentic experience with new sensations. Design/methodology/approach: In a mixed-method procedure, evidence describing the wine tourists' perceptions and motivations is assessed using a quantitative survey and fitting a structural equation model using the PLS algorithm. Complementing evidence through qualitative interviews with Indian entrepreneurs on designing a glocalized experience is analyzed. Findings: Spillover from international travel is the most relevant driver of wine tourism in India. However, types of wines and the experiences are adjusted to the local conditions. The winemakers are remarkably advanced in implementing environmentally sustainable production and avoiding over tourism which perfectly meets their clients' expectations. Research limitations/implications: Entrepreneurial creation theory as described by Alvarez and Barney (2007) is illustrated in the Asian glocalisation context giving special attention to the entrepreneur's individual capabilities as called by Helfat and Peteraf (2015) and Liñán et al. (2020). Practical implications: Conservation of biodiversity and the aesthetics of the local landscape are essential for the vividness of the entrepreneurial ecosystem and the attractiveness for the guests. Social implications: Local adaptation of the touristic experience in terms of entertainment, indigenous cuisines and local specialty supports sustainable development of all the stakeholders. Originality/value: Novelty arises from the projection of the visitors considering the wine cellar experience as an alternative to international travels in combination with analyzing how the entrepreneurs create entrepreneurial opportunities by carving out an authentic experience for their guests.

Whether tectonic strain from the early stage India‐Asia collision has synchronously affected the far‐field margin of the Tibetan Plateau is crucial for understanding plateau deformation and growth processes. However, direct evidence for early far‐field deformation remains scarce. Utilizing illite K‐Ar dating of three fault gouge samples, we established the faulting history of the Leibo fault zone (LFZ) at the southeastern margin of the Tibetan Plateau (SEMTP). Consistent authigenic illite ages of 52 ± 2, 54 ± 12 and 55 ± 6 Ma suggest the reactivated thrust faulting of the LFZ in the Early Cenozoic. Positioned ∼700 km east of the collisional boundary and at the intersection of three blocks with distinct lithospheric rheology in strength/viscosity, this event suggests a quasi‐synchronous far‐field tectonic response in the SEMTP to the India‐Asia collision. Plain Language Summary: Understanding how tectonic strain resulting from the collision between the Indian and Eurasian plates in the Early Cenozoic can spread to the edges of the Tibetan Plateau is crucial for comprehending the plateau's tectonic development. To investigate this question, we used fault gouge, which resulted from the sliding of brittle faults, to directly reveal faulting information. By conducting illite K‐Ar dating on three samples from the Leibo fault zone (LFZ) at the southeastern margin of the Tibetan Plateau (SEMTP), we found consistent ages of newly formed illite, 52 ± 2, 54 ± 12, and 55 ± 6 million years ago. Since this type of minerals form simultaneously with faulting, these ages reveal a reactivated thrust faulting event of the LFZ, suggesting a nearly simultaneous response of faulting in the SEMTP to the early stage of the India‐Asia collision. Key Points: Fault gouge illite K‐Ar dating is used to establish the faulting history of the Leibo fault zone, SE margin of the Tibetan PlateauThree consistent authigenic illite ages of ∼55, ∼54, and ∼52 Ma suggest a reactivated thrust faulting event of the Leibo fault zoneThis event indicates a quasi‐synchronous far‐field response of the SE margin of the Tibetan Plateau to the India‐Asia collision [ABSTRACT FROM AUTHOR]

We describe the use of regional relaxation ("nudging") experiments carried out in initialised hindcasts to shed light on the contribution from particular regions to the errors developing in the Asian Summer Monsoon. Results so far confirm previous hypotheses that errors in the Maritime Continent region contribute substantially to the East Asia Summer Monsoon (EASM) circulation errors through their effects on the Western North Pacific Subtropical High. Locally forced errors over the Indian region also contribute to the EASM errors. Errors arising over the Maritime Continent region also affect the circulation and sea surface temperatures in the Equatorial Indian Ocean region, contributing to a persistent error pattern resembling a positive Indian Ocean Dipole phase. This is associated with circulation errors over India and the strengthening and extension of the westerly jet across southeast Asia and the South China Sea into the Western Pacific, thereby affecting the ASM circulation and rainfall patterns as a whole. However, errors developing rapidly in the deeper equatorial Indian Ocean, apparently independently of the atmosphere errors, are also contributing to this bias pattern. Preliminary analysis of nudging increments over the Maritime Continent region suggests that these errors may at least partly be related to deficiencies in the convection and boundary layer parametrisations.

The increased detection of thyroid nodules in the human population has led to an increase in the number of thyroid surgeries without an improvement in survival outcomes. Though the choice for surgery is straightforward in malignant thyroid nodules, the decision is far more complex in those nodules that get categorized into indeterminate thyroid nodules (ITN) by fine needle aspiration. Therefore, there is a pressing need to develop a tool that will aid in decision-making among the ITN. In this context, the development of various molecular testing (MT) panels has helped to confirm or rule out malignancy, reducing unnecessary surgeries and potentially guiding the extent of surgery as well. Currently, such tests are widely used among the Western population but these MT panels are not used by the South Asian population because of non-availability of validated panels and the high cost involved. There is a need to develop a suitable panel which is population-specific and validate the same. In this review, we would focus on current trends in the management of ITN among the South Asian population and how to develop a novel MT panel which is cost-effective, with high diagnostic accuracy obviating the need for expensive panels that already exist.

Background WHO estimates that seasonal influenza epidemics result in three to five million cases of severe illness (hospitalisations) every year. We aimed to improve the understanding of influenza-associated hospitalisation estimates at a national and global level. Methods We performed a systematic literature review of English- and Chinese-language studies published between 1995 and 2020 estimating influenza-associated hospitalisation. We included a total of 127 studies (seven in Chinese) in the meta-analysis and analyzed their data using a logit-logistic regression model to understand the influence of five study factors and produce national and global estimates by age groups. The five study factors assessed were: 1) the method used to calculate the influenza-associated hospitalisation estimates (rateor time series regression-based), 2) the outcome measure (divided into three envelopes: narrow, medium, or wide), 3) whether every case was laboratory-confirmed or not, 4) whether the estimates were national or sub-national, 5) whether the rates were based on a single year or multiple years. Results The overall pooled influenza-associated hospitalisation rate was 40.5 (95% confidence interval (CI) = 24.3-67.4) per 100 000 persons, with rates varying substantially by age: 224.0 (95% CI = 118.8-420.0) in children aged 0-4 years and 96.8 (95% CI = 57.0-164.3) in the elderly aged >65 years. The overall pooled hospitalisation rates varied by calculation method; for all ages, the rates were significantly higher when they were based on rate-based methods or calculated on a single season and significantly lower when cases were laboratory-confirmed. The national hospitalisation rates (all ages) varied considerably, ranging from 11.7 (95% CI = 3.8-36.3) per 100 000 in New Zealand to 122.1 (95% CI = 41.5-358.4) per 100 000 in India (all age estimates). Conclusions Using the pooled global influenza-associated hospitalisation rate, we estimate that seasonal influenza epidemics result in 3.2 million cases of severe illness (hospitalisations) per annum. More extensive analyses are required to assess the influence of other factors on the estimates (e.g. vaccination and dominant virus (sub)types) and efforts to harmonize the methods should be encouraged. Our study highlights the high rates of influenza-associated hospitalisations in children aged 0-4 years and the elderly aged 65+ years. [ABSTRACT FROM AUTHOR]

Background In South Asia, women often experience intimate partner violence (IPV) and have limited access to maternal health services (MHS). However, the effects of IPV on antenatal care (ANC) visits remain unclear. This study aimed to examine the impact of IPV of different forms and severities on ANC visits in South Asia. Methods This cross-sectional study used the latest available data from demographic and health surveys conducted in Bangladesh, India, Afghanistan, Nepal, Maldives, and Pakistan. The study sampled 4467 women who had given birth within the past 12 months and were interviewed for IPV. IPV was measured by binary variables indicating the presence of physical violence (PV), categorised into less severe (LSPV) and severe physical violence (SPV), emotional violence (EV), and sexual violence (SV). ANC utilization was measured using binary variables indicating whether respondents had any, at least four, or at least eight ANC visits, as recommended by World Health Organization (WHO). Logistic regressions adjusted for survey weights were used to assess associations between ANC utilization and exposure to IPV during pregnancy and lifetime. Results The prevalence of LSPV, SPV, EV, and SV during pregnancy were 14.5%, 4.4%, 11.6%, and 4.1%. LSPV experience during pregnancy was associated with decreased likelihoods of at least four ANC visits (odds ratio (OR) = 0.55; 95% confidence interval (CI) = 0.40-0.76) and eight ANC visits (OR = 0.53; 95% CI = 0.31-0.90). Results of lifetime exposure to IPV followed similar patterns. Lifetime exposure to LSPV was associated with decreased likelihoods of at least four ANC visits (OR = 0.55; 95% CI = 0.41-0.74) and eight ANC visits (OR = 0.47; 95% CI = 0.29-0.77). Conclusion This study highlights the negativities of LSPV on the frequency of women seeking ANC visits. Policies are necessary to identify women at risk of the often-overlooked LSPV early and provide protective interventions to promote maternal health in South Asia. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to identify and elucidate on the different forms and antecedents of customer misbehaviour in the service industry of the emerging country particularly India. Design/methodology/approach: This study adopts a bibliometric analysis approach using bibliophagy software and thematic analysis to reveal four themes: "forms of customer misbehaviour"; "antecedents of such misbehaviour"; "changes in the personal and work behaviour of employees and management"; and "measures to reduce customer misbehaviour". These are combined and interrelated to extant theories and empirical data to ultimately produce a comprehensive model on the subject. Findings: This study finds the antecedents and analyses different forms of customer misbehaviour from Asian customer perspectives. A thematic output is provided which policymakers and other researchers can use to develop various policies and which other related research could use as inputs in the area or consumer behaviour and emerging countries. Research limitations/implications: This study contributes to the field of behavioural studies, especially in the Asian context. Policymakers and future researchers can use these findings to understand different customer-related issues from Asian customer perspective. However, the focus on the Indian consumer market as an emerging country in Asia limits the applicability and generalizability of the study for all emerging countries. Originality/value: The originality and value of this study is related to its pioneering use of bibliometric and thematic analysis from the Asian service context. The value of such research work is associated with both scholarly and executive implications. Regarding the latter, this study examines the myopic nature of uncivil behaviour and helps service firms to understand and manage its different forms, conclusively also providing practicable executive directions on the problem.

Cretaceous‐Miocene sedimentary rocks in the Nepalese Lesser Himalaya provide an opportunity to decipher the timing of India‐Asia collision and unroofing history of the Himalayan orogen, which are significant for understanding the growth processes of the Himalayan‐Tibetan orogen. Our new data indicate that detrital zircon ages and whole‐rock Sr‐Nd isotopes in Cretaceous‐Miocene Lesser Himalayan sedimentary rocks underwent two significant changes. First, from the Upper Cretaceous‐Palaeocene Amile Formation to the Eocene Bhainskati Formation, the proportion of late Proterozoic‐early Palaeozoic zircons (quantified by an index of 500–1200 Ma/1600–2800 Ma) increased from nearly 0 to 0.7–1.4, and the percentage of Mesozoic zircons decreased from ca. 14% to 5–12%. The whole‐rock 87Sr/86Sr and εNd(t = 0) values changed markedly from 0.732139 and −17.2 for the Amile Formation to 0.718106 and −11.4 for the Bhainskati Formation. Second, from the Bhainskati Formation to the lower‐middle Miocene Dumri Formation, the index of 500–1200 Ma/1600–2800 Ma increased to 2.2–3.7 and the percentage of Mesozoic zircons abruptly decreased to nearly 0. The whole‐rock 87Sr/86Sr and εNd(t = 0) values changed significantly to 0.750124 and −15.8 for the Dumri Formation. The εHf(t) values of Early Cretaceous zircons in the Taltung Formation and Amile Formation plot in the U‐Pb‐εHf(t) field of Indian derivation, whereas εHf(t) values of Triassic‐Palaeocene zircons in the Bhainskati Formation demonstrate the arrival of Asian‐derived detritus in the Himalayan foreland basin in the Eocene based on available datasets. Our data indicate that (1) the timing of terminal India‐Asia collision was no later than the early‐middle Eocene in the central Himalaya, and (2) the Greater Himalaya served as a source for the Himalayan foreland basin by the early Miocene. When coupled with previous Palaeocene‐early Eocene provenance records of the Tethyan Himalaya, our new data challenge dual‐stage India‐Asia collision models, such as the Greater India Basin hypothesis and its variants and the arc–continent collision model.

The accidental release of toxic gases leads to fire, explosion, and acute toxicity, and may result in severe problems for people and the environment. The risk analysis of hazardous chemicals using consequence modelling is essential to improve the process reliability and safety of the liquefied petroleum gas (LPG) terminal. The previous researchers focused on single-mode failure for risk assessment. No study exists on LPG plant multimode risk analysis and threat zone prediction using machine learning. This study aims to evaluate the fire and explosion hazard potential of one of Asia's biggest LPG terminals in India. Areal locations of hazardous atmospheres (ALOHA) software simulations are used to generate threat zones for the worst scenarios. The same dataset is used to develop the artificial neural network (ANN) prediction model. The threats of flammable vapour cloud, thermal radiations from fire, and overpressure blast waves are estimated in two different weather conditions. A total of 14 LPG leak scenarios involving a 19 kg capacity cylinder, 21 tons capacity tank truck, 600 tons capacity mounded bullet, and 1350 tons capacity Horton sphere in the terminal are considered. Amongst all scenarios, the catastrophic rupture of the Horton sphere of 1350 MT capacity presented the most significant risk to life safety. Thermal flux of 37.5 kW/ m2 from flames will damage nearby structures and equipment and spread fire by the domino effect. A novel soft computing technique called a threat and risk analysis-based ANN model has been developed to predict threat zone distances for LPG leaks. Based on the significance of incidents in the LPG terminal, 160 attributes were collected for the ANN modelling. The developed ANN model predicted the threat zone distance with an accuracy of R2 value being 0.9958, and MSE being 202.9061 in testing. These results are evident in the reliability of the proposed framework for safety distance prediction. The LPG plant authorities can adopt this model to assess the safety distance from the hazardous chemical explosion based on the prior forecasted atmosphere conditions from the weather department.

Infant massage is a highly prevalent traditional practice in India and other parts of Asia. Clear guidance on safe and effective uses of infant massage is lacking especially in the contemporary times when the traditional knowledge is on the verge of extinction and preparations may differ from in the past. This paper presents a consensus guidance in the form of a standardized protocol for routine massage of infants in home settings. Furthermore, a feasible method to develop an integrative protocol involving traditional and modern medicine experts is described. A modified e-Delphi method was used to develop the protocol. A group of seventeen experts, including academicians and practitioners from disciplines as modern paediatrics, Ayurveda paediatrics, Physiotherapy and Naturopathy participated in three rounds of a Delphi study to evolve the consensus guidance. The present protocol for massage of infants born beyond 34 weeks of gestation and weighing above 1.8 kg is recommended for use by care givers. This provides guidance on the preparation for infant massage such as when to begin massaging the infant, checking fitness of the infant for massage, the appropriate time, environment, person and substance for infant massage and a detailed description of the procedure for infant massage. Paediatricians, obstetricians and other child care practitioners can use this protocol to guide care givers on how to peform infant massage. [ABSTRACT FROM AUTHOR]

India has used civilizational discourses as part of its foreign policy to articulate its rise and rightful place in the world order. This article primarily examines India's civilizational arguments in south Asia. India's civilizational arguments in the region demand scrutiny as the neighbourhood is a theatre of contestation between territorial India and the claims of its civilizational space. Analysing historical accounts on Indian civilization, official documents and domestic narratives in India about south Asia, the article makes three points. First, India's civilizational articulation oscillates between two paradigmatic and contrasting representations of Nehruvianism and Hindutva variants. Second, it is argued that despite the ascendancy of Hindutva 's civilizational symbolism since 2014, India's south Asia policy shows no paradigmatic change. Finally, it points to how the Hindutva project may be detrimental to India's self-image and dealings in south Asia. The article argues that while there is no official corroboration of Hindutva 's claims in India's south Asia policy, the increasing salience of the domestic discussions around Akhand Bharat (undivided India) invites complications for India in its neighbourhood. India's Hindutva -driven civilizational claims raise anxieties of an Indian cultural hegemony in an asymmetric region splintered across territorial and nationalistic lines. [ABSTRACT FROM AUTHOR]

This study aimed to analyze the research trends on salivary oxidative stress associated with dental caries and to perform bibliometric approaches for existing publications on this association. A search was performed using the Web of Science Core Collection, without any restriction of language or publication year. The number of periodicals with the most published articles in this theme, most published authors and keywords were mapped; other metrics were also evaluated such as the countries that have more research on the subject and the period in which there were more publications on the subject. During the knowledge mapping, the most frequent experimental designs were analyzed, type of saliva collection, stage of caries disease, evaluated oxidative parameters were retrieved and analyzed from each manuscript. Between the 43 selected articles, the Journal of Clinical Pediatric Dentistry was the periodical appearing the most with 4 published articles. The authors who published the most were Celec, P., Tothova, L., Hegde, A.M., Shetty, S., Antoniali, C., and Pessan, JP with three articles each, and a total of 180 keywords representing the evolution of the theme. India and Asia were found to be the country and continent with most publications, respectively. Most articles collected non-stimulated total saliva, with total antioxidant capacity being the parameter most often evaluated. The type of study that appeared the most was cross-sectional studies, and articles published in the period of 2017–2022 were the most frequent. Studies show that dental caries can be associated to the changes in salivary oxidative biochemistry with an increase in lipid peroxidation, a biomarker of oxidative damage, and an increase in antioxidant capacity in chronic caries, in response to cariogenic challenge. Some studies evidence the reduction of lipid peroxidation after treatment of the carious lesion. Our findings reveal worldwide research trends, as well as a clearer knowledge of the evolution and future scenarios of this issue, also showing the mechanisms associating dental caries with changes in salivary oxidative biochemical parameters are not clear.

COVID-19 is an infectious disease that has widened the gap between victims and non-victims in society. Understanding how individuals support and assist COVID-19 sufferers in a pandemic crisis is critical. Thus, this study aims to qualitatively evaluate the prosocial intention and types of prosocial behavior toward COVID-19 victims by low socioeconomic individuals from India and Indonesia's collectivistic societies. We conducted semi-structured and in-depth interviews during the lockdown from March to May 2020, via phone and in-person, using a purposive selection of respondents (total n = 50). The data were analyzed using the qualitative synthesis method. Five themes were discovered: 1) too scared to help, 2) love to help but scared: moral dilemma, 3) informing authority who knows how to handle, 4) caring, sharing, and supporting, but with a distance, and 5) helping at one's personal health risk. This study highlights that prosocial intentions range from minor acts of kindness to self-harm and out-of-bounds acts of kindness for COVID-19 victims. [ABSTRACT FROM AUTHOR]

Background: High prevalence of smartphone addiction among medical students may contribute to adverse physical and mental health outcomes. Aim: To estimate the prevalence of smartphone addiction, and explore the influencing factors and related mental health symptoms of smartphone addiction among Asian medical students. Design: Systematic review and meta-analysis. Methods: PubMed (MEDLINE), the Cochrane Central Register of Controlled Trials, and EMBASE were searched for relevant literature from the inception to September 10, 2021. Using Stata software 11.0, the meta-analysis of prevalence and the influencing factors of smartphone addiction were determined with 95% confidence intervals. Results: Nineteen articles, published between 2014 and 2019, were included, producing medical student studies from seven different Asian countries. The included studies were conducted in India (n = 11) and Malaysia (n = 3), with China, Saudi Arabia, Turkey, Nepal, and Iran each contributing one study. Among a total of 5,497 medical students, the participants included 3,214 females, of whom 2,181 were medical students with smartphone addiction. The prevalence of smartphone addiction among Asian medical students was 41.93% (95% CI [36.24%, 47.72%]). The influencing factors of smartphone addiction among medical students included gender, duration of smartphone use, smartphone function, and marital status. Ten studies (52.63%) explored related mental health symptoms of smartphone addiction among Asian medical students. Smartphone addiction was positively correlated with poor sleep quality (r = .17-.31), stress (r = .30-.40), anxiety, depression, neuroticism, and general health among Asian medical students. Conclusion: Smartphone addiction is highly prevalent among Asian medical students. Smartphone addiction may adversely affect mental health, resulting in sleep disturbance, stress, anxiety, depression, and neuroticism. It is necessary to take appropriate precautionary actions and interventions to prevent smartphone overuse among medical students. [ABSTRACT FROM AUTHOR]

Bacteria control gene expression by quorum sensing (QS) mechanism owing to producing small signal molecules associated with population density. Both gram-positive and gram-negative bacteria use QS to manage various physiological characteristics, including bioluminescence, virulence gene expression, biofilm formation, and antibiotic resistance. Impatience balsamina is a flowering, perennial and annual herb indigenous to southern Asia in India. All parts of Impatience balsamina have a therapeutic effect on different diseases. This study evaluated the anti-quorum sensing activity of leaf extract of Impatience balsamina by examining its action on Violacein production by Chromobacterium violaceum, a biosensor strain, and Biofilm, Pyocyanin, Protease, and Chitinase production by the reference strain Pseudomonas aeruginosa PA 01. Minimum inhibitory concentration (MIC) for Pseudomonas aeruginosa PA 01was 3.125mg/ml. A concentration of 1.563mg/ml (sub-MIC) showed inhibition of 100% on Las A protease, 78.42% on chitinase, 30.75% on biofilm, and 93.33% on pyocyanin production by Pseudomonas aeruginosa PA 01. This article displayed the quorum quenching activity of Impatience balsamina by hindering the quorum-sensing controlled characteristics of bacteria without killing it, which reduces the proneness of drug resistance in bacteria, a globally accepted emerging problem in the medical field.

The melon fruit fly, Zeugodacus cucurbitae (Coquillett) (Diptera: Tephritidae), is an important pest of cucurbits throughout India, South‐East Asia and Pacific islands. Attractants of female melon fly are of relevance as they could enhance the efficacy of current pest management practices. Previous studies have revealed several host fruits to be attractive to gravid female melon flies. However, studies on the chemical compounds responsible for their attraction are meagre. As an initial part of our study, we evaluated the response of gravid female melon flies to headspace volatiles of four different cucurbit fruits, namely bitter gourd, cucumber, ridge gourd and snake gourd. Electrophysiological and multiple‐choice olfactometer assays revealed that gravid melon flies significantly preferred ridge gourd volatiles over volatiles of other cucurbit fruits. Coupled gas chromatography‐electroantennogram detection (GC‐EAG) analysis of headspace volatiles of ridge gourd to gravid melon flies identified six EAG‐active compounds, namely α‐pinene, 1‐octen‐3‐ol, p‐cymene, p‐ethyl‐benzaldehyde, methyl salicylate and p‐cymen‐7‐ol. Individual EAG‐active compounds, except α‐pinene, were significantly attractive to gravid female flies. Moreover, a synthetic blend with the concentration and ratio of compounds as in the ridge gourd headspace samples was attractive to flies. Though, in a dual‐choice test, the preference of gravid melon flies to a synthetic blend was not significantly different from preference to ridge gourd volatile samples. Taken together, our results show that the synthetic blend of ridge gourd volatiles may be used to develop a potential lure for female melon fly, Z. cucurbitae. [ABSTRACT FROM AUTHOR]

Knowing the pre-collisional extent of the northern Indian Plate margin ('Greater India') is vital to understanding the tectonic evolution of the India–Asia collision and the formation of the Himalayan–Tibetan orogen. However, suitable geological units for palaeomagnetic investigations along the Himalayan belt are limited, which makes it difficult to reconstruct Greater India during the pre-collisional period in Late Cretaceous to Palaeogene. Often the palaeomagnetic results from the Zongpu Formation at Gamba in southern Tibet (∼88.5°E) were used for estimates of Greater India, but their validity was recently questioned. As a contribution to closing the data gap, we performed a palaeomagnetic study of the Palaeocene/Lower Eocene Dibling limestone (DL) in the western Tethyan Himalaya of Zanskar (34.0°N/76.6°E). The results from 27 sites revealed a well grouping (k  = 71.7) syntectonic magnetization with best grouping at 52 per cent unfolding. The remagnetization of the DL was acquired shortly after ∼54 Ma, at the latest at ∼49 Ma, and is probably carried by fine-grained magnetite formed during the early orogenic phase. Assuming proportional tilting of the fold limbs, the corresponding palaeolatitude of 11.8 ± 2.4°N suggests a maximum Greater India extent of 810 ± 420 km and a first continental contact with the southern Eurasian margin at ∼12°N in the western part of the suture zone. The tectonostratigraphic equivalence of the DL with the Zongpu Formation at Gamba and a great similarity in their magnetic properties supports a secondary origin of the Gamba results. Through understanding the mechanism of remagnetization in the DL, an early orogenic remanence acquisition is also indicated for the Zongpu Formation, and thus the Gamba results deserve further credit for Greater India reconstructions. However, we note a large inconsistency of the available Late Cretaceous and Palaeogene palaeolatitude data from the Tethyan Himalaya by up to ∼20°, corresponding to differences of up to ∼2000 km in the size of Greater India. These discrepancies require further palaeomagnetic work in the Tethyan Himalaya, and in particular we recommend comparative studies at same locations and of same units. [ABSTRACT FROM AUTHOR]

Long‐distance lateral magma propagation may reflect the complex interaction between regional tectonics and crustal uplift. Here, we report observations on the Taxkorgan intrusive complex (TIC) of the Central Pamir. TIC is a 70 km long, 10–18 km wide, north‐northwest–elongated body intruded into mid‐upper crust in parallel with, and close to, the Kongur Shan Extensional System. New zircon U‐Pb dating shows that syenite samples exhibit a clear younging pattern from south to north along the pluton axis within an interval between 11.5 and 10.3 Ma, which is interpreted as lateral magma propagation from a single feeder zone at its northwestern margin. The lateral magma propagation was caused by a combination of crustal rigidity differences, and a topography‐induced pressure gradient that is nearly orthogonal to the least compressive stress. We propose that long‐distance lateral magma propagation plays an important role in plateau expansion, restraining the thickness and elevation of the Pamir Plateau. Plain Language Summary: Long‐distance lateral magma propagation within the crust has been documented for diverse magmatic systems. The Miocene Taxkorgan intrusive complex was formed during India‐Asia collision in the Central Pamir Plateau, and it consists of a syenite pluton and several discrete lobes of monzogranites. New SIMS zircon U‐Pb dating results shows that monzogranites across TIC have overlapping ages between 12.4 and 12.2 Ma, indicating they were emplaced from a series of synchronous and independent magma feeder zones. In contrast, syenite samples exhibit a clear younging pattern from south to north within an interval between 11.5 and 10.3 Ma. The pattern of decreasing ages along the pluton axis is interpreted as lateral magma propagation from a single feeder zone at its northwestern margin. It is inferred that long‐distance lateral magma propagation, such as documented for the Taxkorgan intrusive complex, played a key role in plateau expansion, restraining the thickness and elevation of the Pamir Plateau. Key Points: Taxkorgan intrusive complex (TIC) syenite pluton shows a clear younging pattern from south to north within an interval between 11.5 and 10.3 MaTIC syenite pluton formed by lateral magma propagation from a single feeder zone at its northwestern marginLong‐distance lateral magma propagation plays an important role in plateau expansion, restraining the thickness and elevation of Plateau [ABSTRACT FROM AUTHOR]

Currently no standardized tools are available in the Indian languages to assess changes in cognition. Our objectives are to culturally adapt the Alzheimer's disease Assessment Scale–Cognitive Subscale (ADAS-Cog) for use in India and to validate the Tamil version in an urban Tamil-speaking older adult population. Two panels of key stakeholders and a series of qualitative interviews informed the cultural and linguistic adaptation of the ADAS-Cog-Tamil. Issues related to levels of literacy were considered during the adaptation. Validation of the ADAS-Cog-Tamil was completed with 107 participants − 54 cases with a confirmed diagnosis of mild-moderate dementia, and 53 age, gender and education matched controls. Concurrent validity was examined with the Vellore Screening Instrument for Dementia (VSID) in Tamil. Internal consistency using Cronbach's alpha, sensitivity and specificity data using the Area under the Receiver Operating Characteristics (AUROC) curve values were computed. Inter-rater reliability was established in a subsample. The ADAS-Cog-Tamil shows good internal consistency (α = 0.91), inter-rater reliability and concurrent validity (with VSID-Patient version: r = –0.84 and with VSID-Caregiver version: r = –0.79). A cut-off score of 13, has a specificity of 89% and sensitivity of 90% for the diagnosis of dementia. ADAS-Cog-Tamil, derived from a rigorous, replicable linguistic and cultural adaptation process involving service users and experts, shows good psychometric properties despite the limitations of the study. It shows potential for use in clinical settings with urban Tamil speaking populations. The English version of the tool derived from the cultural adaptation process could be used for further linguistic adaptation across South Asia. [ABSTRACT FROM AUTHOR]

Background: To identify and describe the breast cancer-specific health-related quality of life (HRQoL) instruments with evidence of validation in the breast cancer population for potential use in patients treated for breast cancer (excluding surgery).Methods: We conducted a systematic literature review using PubMed, Embase, and PsycINFO databases to identify articles that contain psychometric properties of HRQoL instruments used in patients with breast cancer. Relevant literature from January 1, 2009, to August 19, 2019, was searched. Articles published in English that reported psychometric properties (reliability, validity) of HRQoL instruments were identified.Results: The database search yielded 613 unique records; 131 full-text articles were reviewed; 80 articles presented psychometric data for instruments used in breast cancer (including generic measures). This article reviews the 33 full articles describing psychometric properties of breast cancer-specific HRQoL instruments: EORTC QLQ-C30, EORTC QLQ-BR23, FACT-B, FBSI, NFBSI-16, YW-BCI36, BCSS, QuEST-Br, QLICP-BR, INA-BCHRQoL, and two newly developed unnamed measures, one by Deshpande and colleagues (for use in India) and one by Vanlemmens and colleagues (for use among young women and their partners). The articles that described the EORTC QLQ-C30, QLQ-BR23, and FACT-B centered on validating translations, providing additional support for content validity, and demonstrating acceptability of electronic patient-reported outcome administration. Psychometric properties of the measures were acceptable. Several new measures have been developed in Asia with an emphasis on development on cultural relevance/sensitivity. Others focused on specific populations (i.e., young women with breast cancer).Conclusions: Historically, there have been limited options for validated measures to assess HRQoL of patients with breast cancer. A number of new measures have been developed and validated, offering promising options for assessing HRQoL in this patient population. This review supports the reliability and validity of the EORTC QLQ-C30 and FACT-B; new translations and electronic versions of these measures further support their use for this population.

The World Health Organization recommends salt reduction as a cost-effective intervention to prevent noncommunicable diseases. Salt-reduction interventions are best tailored to the local context, taking into consideration the varying baseline salt-intake levels, population's knowledge, attitude, and behaviors. Fundamental to reduction programs is the source of dietary salt-intake. In South Asian countries, there is a paucity of such baseline evidence around factors that contribute to community salt intake. Upon reviewing the electronic literature databases and government websites through March 31, 2021, we summarized dietary salt intake levels and aimed to identify major sources of sodium in the diet. Information on the current salt reduction strategies in eight South Asian countries were summarized, namely Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. One hundred twelve publications (out of identified 640) met our inclusion-exclusion criteria for full text review. Twenty-one studies were included in the review. Quality of the included studies was assessed using the US National Heart, Lung, and Blood Institute assessment tool. The primary result revealed that mean salt intake of South Asian countries was approximately twice (10 g/day) compared to WHO recommended intake (< 5 g/day). The significant proportion of salt intake is derived from salt additions during cooking and/or discretionary use at table. In most South Asian countries, there is limited data on population sodium intake based on 24-h urinary methods and sources of dietary salt in diet. While salt reduction initiatives have been proposed in these countries, they are yet to be fully implemented and evaluated. Proven salt reduction strategies in high-income countries could possibly be replicated in South Asian countries; however, further community-health promotion studies are necessary to test the effectiveness and scalability of those strategies in the local context.

The India-Asia collision is an outstanding smoking gun in the study of continental collision dynamics. How and when the continental collision occurred remains a long-standing controversy. Here we present two new paleomagnetic data sets from rocks deposited on the distal part of the Indian passive margin, which indicate that the Tethyan Himalaya terrane was situated at a paleolatitude of ∼19.4°S at ∼75 Ma and moved rapidly northward to reach a paleolatitude of ∼13.7°N at ∼61 Ma. This implies that the Tethyan Himalaya terrane rifted from India after ∼75 Ma, generating the North India Sea. We document a new two-stage continental collision, first at ∼61 Ma between the Lhasa and Tethyan Himalaya terranes, and subsequently at ∼53−48 Ma between the Tethyan Himalaya terrane and India, diachronously closing the North India Sea from west to east. Our scenario matches the history of India-Asia convergence rates and reconciles multiple lines of geologic evidence for the collision. [ABSTRACT FROM AUTHOR]

The increasing density of geodetic measurements makes it possible to map surface strain rate in many zones of active tectonics with unprecedented spatial resolution. Here we show that the strain tensor rate calculated from GPS in the India–Asia collision zone represents well the strain released in earthquakes. This means that geodetic data in the India–Asia collision zone region can be extrapolated back in time to estimate strain buildup on active faults, or the kinematics of continental deformation. We infer that the geodetic strain rates can be assumed stationary through time on the timescale needed to build up the elastic strain released by larger earthquakes, and that they can be used to estimate the probability of triggering earthquakes. We show that the background seismicity rate correlates with the geodetic strain rate. A good fit is obtained assuming a linear relationship (⁠|$\dot{N} = \lambda \ \cdot \dot{\epsilon }$|⁠ , where |$\dot{N}$| is the density of the rate of M w ≥ 4 earthquakes, |$\dot{\epsilon }$| is strain rate and λ = 2.5 ± 0.1 × 10−3 m−2), as would be expected from a standard Coulomb failure model. However, the fit is significantly better for a non-linear relationship (⁠|$\dot{N} = \gamma _1 \cdot \dot{\epsilon }^{\gamma _2}$| with γ1 = 2.5 ± 0.6 m−2 and γ 2 = 1.42 ± 0.15). The b -value of the Gutenberg–Richter law, which characterize the magnitude–frequency distribution, is found to be insensitive to the strain rate. In the case of a linear correlation between seismicity and strain rate, the maximum magnitude earthquake, derived from the moment conservation principle, is expected to be independent of the strain rate. By contrast, the non-linear case implies that the maximum magnitude earthquake would be larger in zones of low strain rate. We show that within areas of constant strain rate, earthquakes above M w 4 follow a Poisson distribution in time and and are uniformly distributed in space. These findings provide a framework to estimate the probability of occurrence and magnitude of earthquakes as a function of the geodetic strain rate. We describe how the seismicity models derived from this approach can be used as an input for probabilistic seismic hazard analysis. This method is easy to automatically update, and can be applied in a consistent manner to any continental zone of active tectonics with sufficient geodetic coverage. [ABSTRACT FROM AUTHOR]

The Kohistan Island Arc (KIA) occupies the northwestern region of the Himalayan Mountains, sandwiched between Asia and India plates. Its formation, collision with plate boundaries, and evolution has been controversially discussed for a couple of decades. To better understand this, a palaeomagnetic study has been conducted on the Jutal dykes (ca. 75 Ma), intruded in the northeastern part of the KIA. Comprehensive rock magnetic investigations reveal that the magnetic carrier minerals are pyrrhotite and magnetite. An intermediate temperature component (ITC) predominates the natural remanent magnetization and shows good coincidence within-site; it is carried by pyrrhotite and is considered reliable, yielding a mean direction at D g/ I g = 11.5°/39.9° (k g = 28.4, α 95 = 3.5°) before and D s/ I s = 8.6°/12.1° (k s = 5.1, α 95 = 9.1°) after tilt correction. A high-temperature component that is carried by magnetite exhibits random distribution within-site. The fold test for the ITC is negative, indicating a post-folding origin. Scanning electron microscopy combined with energy-dispersive X-ray spectroscopy indicates that the magnetic carrier minerals were influenced by metamorphism or thermochemical fluids. The comparison of mean palaeolatitude (22.6 ± 3.5°N) of the ITC with the collisional settings and thermal history of the study area implies that the remagnetization occurred at ∼50–35 Ma, consistent with the previous reported palaeomagnetic data of the KIA. We propose a tectonic model that shows the evolution of the Jutal dykes, supporting the concept that India collided with the KIA first, followed by a later collision with Asia.

Granites are generally the final products of crustal anatexis. The composition of the initial melts may be changed by fractional crystallization during magma evolution. Thus, it is crucial to retrieve the temperature and pressure conditions of crustal anatexis on the basis of the composition of the initial melts rather than the evolved melts. Here we use a suite of ∼46–41 Ma granites from the Himalayan orogen to address this issue. These rocks can be divided into two groups in terms of their petrological and geochemical features. One group has high maficity (MgO + FeOt = 2–4 wt%) and mainly consists of two-mica granites, and is characterized by apparent adakite geochemical signatures, including high Sr concentrations and Sr/Y and La/Yb ratios, and low concentrations of heavy rare earth elements and Y. The other group has low maficity (MgO + FeOt <1 wt%) and consists of subvolcanic porphyritic granites and garnet/tourmaline-bearing leucogranites. This group does not possess apparent adakite signatures. The low-maficity group (LMG) has lower MgO + FeOt contents and the high-maficity group (HMG) has higher Mg# compared with initial anatectic melts determined by experimental petrology and melt inclusions studies. Petrological observations indicate that the HMG and the LMG can be explained as a crystal-rich cumulate and its fractionated melt, respectively, such that the initial anatectic melt is best represented by an intermediate composition. Such a cogenetic relationship is supported by the comparable Sr–Nd isotopic compositions of the two coeval groups. However, these compositions are also highly variable, pointing to a mixed source that was composed of amphibolite and metapelite with contrasting isotope compositions. We model the major and trace element compositions of anatectic melts generated by partial melting of a mixed source at four apparent thermobarometric ratios of 600, 800, 1000 and 1200 °C GPa–1. Modeling results indicate that melt produced at 1000 °C GPa–1 best matches the major and trace element compositions of the inferred initial melt compositions. In particular, a binary mixture generated from 10 vol% partial melting of amphibolite and 30 vol% melting of metapelite at 850 ± 50 °C and 8·5 ± 0·5 kbar gives the best match. Therefore, this study highlights that high thermobarometric ratios and subsequent fractional crystallization are responsible for the generation of the apparent adakitic geochemical signatures, rather than melting at the base of the thickened crust as previously proposed. The thermal anomaly responsible for the Eocene magmatism in the Himalayan orogen was probably related to asthenosphere upwelling in response to rollback of the subducting Neo-Tethyan oceanic slab at the terminal stage of continental collision between India and Asia. As such, a transition in dynamic regime from compression to extension is necessary for the generation of high thermobarometric ratios in continental collision zone. Therefore, after correcting for potential effects of fractional crystallization and crystal accumulation on melt composition, granite geochemistry coupled with thermodynamic modeling can better elucidate the petrogenesis of granites and the geodynamic mechanisms associated with anatexis at convergent plate boundaries.

Sheath blight of rice caused by Rhizoctonia solani is regarded as one of the most widely distributed diseases of rice, and is one of the major production constraints for rice in India and most rice-growing countries of Asia. Biological control of plant diseases using antagonistic bacteria is now considered as a promising alternative to the use of hazardous chemical fungicides or bactericides. Several bacterial endophytes have been reported to support growth and improve the health of the plants and therefore, may be important as biocontrol agents. In the present study, putative antifungal metabolites were extracted from rice foliage endophyte Lysinibacillus sphaericus KJ872548 by solvent extraction methods and purified using HPTLC techniques. Separated bands were subjected to assess the in vitro antagonistic activity toward rice sheath blight pathogen Rhizoctonia solani using a dual culture method. Partially purified active fraction B2 obtained from HPTLC analysis showed the highest percentage of inhibition (76.9%). GC MS and FTIR analyses of B2 revealed the compound as1, 2-Benzenedicarboxylic acid butyl 2-Ethylhexyl ester, a strong antifungal volatile organic compound. Light microscopic analysis of the fungal mycelium from the dual culture plate of both culture filtrate and 1, 2-Benzenedicarboxylic acid butyl 2-Ethylhexyl ester disclosed strong mycolytic activity as evident by mycelial distractions and shrinkage. This is the first report on antifungal production by endophytic Lysinibacillus sphaericus against R.solani, the rice sheath blight pathogen. The findings of this study biologically prospect the endophyte L.sphaericus as an inexpensive broad spectrum bioagent for eco-friendly, economic and sustainable agriculture. [ABSTRACT FROM AUTHOR]

Deep Earth degassing is a critical forcing factor for atmospheric CO2 variations and palaeoclimate changes in Earth's history. For the Cenozoic, the key driving mechanism of atmospheric CO2 variations remains controversial. Here we analyse three stages of collision-related magmatism in Tibet, which correspond temporally with the three major stages of atmospheric CO2 variations in the Cenozoic and explore the possibility of a causal link between these phenomena. To this end we present geochemical data for the three stages of magmatic rocks in Tibet, which we use to inform a model calculating the continental collision-induced CO2 emission flux associated with the evolving Neo-Tethyan to continental subduction over the Cenozoic. The correlation between our modelled CO2 emission rates and the global atmospheric CO2 curve is consistent with the hypothesis that the India-Asia collision was the primary driver of changes in atmospheric CO2 over the Cenozoic. "Earth degassing is a critical carbon source, but its contribution to Cenozoic atmospheric CO2 variations is not well known. Here, the authors analyse CO2 fluxes on the Tibetan Plateau and suggest that the India-Asia collision was the primary driver of changes in atmospheric CO2 over the past 65 Ma."

Upper Cretaceous to Eocene marine sedimentary sequences of the Yarlung‐Tsangpo Suture Zone (YTSZ) provide critical constraints on the initial process of the India–Asia continental collision and the closure time of the Neo‐Tethyan Ocean. New sedimentological, petrographic, biochronological and detrital zircon age data of Cretaceous–Palaeogene strata from the southern margin of the YTSZ are reported in this study. Detrital zircons from the Lower Cretaceous Gyabula Formation are dominated by Archean to Cambrian U–Pb ages, indicating a likely source originating from the Indian continent. In contrast, zircon ages from the Palaeogene Jiachala Formation are predominantly younger than 200 Ma, with a major peak of ca. 76–187 Ma, which is consistent with a source from either an intra‐oceanic island arc system or the Asian continent. Sixty species of radiolarian fossils obtained from the Gyabula, Zongzhuo and Jiachala Formations provide a regional correlation with the Cretaceous Tethyan realm and Palaeogene low‐latitude biozonation schemes based on the Unitary Association method. The Palaeogene radiolarian zonation UAZ JP10 identified in the Jiachala Formation, when combined with existing absolute age models derived from the Deep Sea Drilling Project and Ocean Drilling Program, indicates an age of ca. 61.8–61.1 Ma. Integration of the biochronological and detrital zircon age data suggests that major changes in provenance occurred at the Indian continental margin, allowing an important timing constraint on the onset of collision to be placed no later than the Danian at ca, 61.8 Ma. This study highlights the significance of focusing on distinct sedimentary sequences in collisional orogens to reconstruct the timing and processes of continental collision events.
