    Quarkonia as probes of initial and final states in small systems with ALICE

    No full text
    The multiple parton−parton interactions (MPIs) are an important element to describe the observed collective flow and strangeness enhancement in high multiplicity pp and p−Pb collisions, the so-called small systems. At LHC energy, MPIs affect both soft and hard scales of the event. Since quarkonium production involves both, it can be an excellent tool to understand the role of MPIs in small systems. Study of multiplicity dependent quarkonium production provides an indirect probe of MPIs in hadronic collisions. Also, relative production of excited-to-ground quarkonium states as a function of multiplicity are sensitive to final state effects. Cross section measurements of different quarkonium states are also important to understand their production mechanisms. In these proceedings, first preliminary results of ψ(2S)-over-J/ψ cross section measurements at mid and forward rapidity (y) from Run 2 and Run 3 pp collisions at √S and 13.6 TeV, respectively will be presented. Preliminary results on ϒ(nS) states (n = 1,2) cross sections and final multiplicity dependent measurements of excited-to-ground states quarkonium yields, at forward y, in pp collisions at √S TeV will be shown. In addition, few performance plots from Run 3 in the quarkonium sector will be presented and discussed.The multiple parton-parton interactions (MPIs) are an important element to describe the observed collective flow and strangeness enhancement in high multiplicity pp and p-Pb collisions, the so-called small systems.

    Towards Sub-regional cooperation: India’s Northeast and Bangladesh

    The South Asian countries have a shared past based on deep-rooted common cultural heritage and historical legacy. The region has demographic and geographical advantages young labour force and a contiguous border. The spatial dimension of regional integration of Northeast India and Bangladesh can be inferred from the historical fact that economic growth of Northeast during the British rule flourished essentially on the strength of its integrated transport network through East Bengal. Inland-water trade between India and Bangladesh is important in linking not only Assam but the region as a whole to Bangladesh. Cost effective trade routes through water ways is more important than land routes for India’s Northeast through the corridors of Bangladesh. Notwithstanding the importance of waterways, the land routes continue to be the safe transit for informal trade between both the countries.Regional cooperation; Northeast India

    AutoMeta-ETD500 contains 500 scanned Electronic Theses and Dissertations (ETDs). This dataset is used to develop a framework called AutoMeta, which automatically extracts seven key metadata fields (e.g., title, author, advisor, university, department, university, and year), which are ubiquitous to ETDs. For this task, the dataset has been derived into the following seven intermediate datasets: a) PDF.zip: This zip file contains 500 ETD samples from different US and non-US universities. b) XML_JSON.zip: This zip file contains 100 ETD metadata that have been downloaded from MIT and Virginia Tech ETD library repositories. c) HTML.zip: This zip file contains the remaining 400 ETD metadata, which have been downloaded from ProQuest. d) Tiff.zip: This zip file contains the Tiff images of cover pages of 500 scanned ETDs. e) noisy.zip: This zip file contains all the noisy data for 500 ETD samples. This is generated by tesseract OCR. f) clean.zip: This zip file contains all the clean data of 500 ETD samples, and this dataset has been manually rectified from noisy data. g) annotated.zip: This zip file contains all annotated data in XML. Annotation is done using the GATE annotation tool

    Effect of radial flow on two particle correlations with identified triggers at intermediate pT in p–Pb collisions at sNN=5.02 TeV

    Results from two-particle correlation between identified triggers (pions (π±), protons (p/p¯)) and un-identified charged particles at intermediate transverse momentum (pT) in p–Pb collisions at sNN=5.02 TeV have been presented. The events generated from a hybrid Monte-Carlo event generator, EPOS 3.107 that implements a flux-tube initial conditions followed by event by event 3+1D viscous hydrodynamical evolution, have been analyzed to calculate two-dimensional correlation functions in Δη–Δϕ. The strength of angular correlations at small relative angles (jet-like correlations), quantified in terms of near-side jet-like per-trigger yield has been calculated as a function of the event multiplicity. The yield associated with pion triggers exhibit negligible multiplicity dependence, while the proton-triggered yield shows a gradual suppression from low to high multiplicity events. In small collision systems like p–Pb where jet modification is expected to be less dominant, the observed suppression may be associated with the hydrodynamical evolution of the bulk system that generates an outward radial flow. Analogous measurements in Au–Au collisions at RHIC energy have shown a hint of dilution in proton-triggered correlation at its highest multiplicity suggesting that the soft physics processes in p–Pb and heavy ion collisions may have qualitative similarity

    “Counter Me!” Female Bodies as Sites of Resistance in the Three Stories of Postcolonial Author Mahasweta Devi

    No full text
    The postcolonial Indian author and activist Mahasweta Devi (1926–2016) depicts the oppression of marginalized women who are indigenous and are of lower castes in the following three stories: Draupadi (1978), Rudali (1993), and Douloti the Bountiful (1993). In this thesis, I argue that each of the female protagonists resist the torture inflicted on them by the patriarchal society by using their bodies as sites of resistance. They retrieve their agencies by defying the exploitation of gender, class, and caste. Draupadi is a story of an indigenous woman named Draupadi (Dopdi), who subverts the humiliation of gang rape by refusing to accept victimhood and by throwing the shame back upon the perpetrators. Rudali is a story of a funeral wailer named Sanichari who, despite terrible obstacles, gains agency by turning her grief into a performative profession. Douloti the Bountiful is a story of a bonded laborer who dies as a sex slave at the age of twenty-seven, forcing the nation to generate a conversation on the rights of bonded laborers. Moreover, her marginalized life and death debunk the national myth of independence and raise the question about why the nation builders entirely excluded her from the body politic. The three stories explain how Devi centers the subaltern female body, which is always found as the Other, the neglected, the one which always lies at the margin. Devi has captured the complexity of the gendered resistance by portraying the different ways these women react to the violence and torture inflicted on them. Devi’s resistance, through her literary works, is an endeavor to counter the influence of religious and political hegemony which has spread its malicious tentacles in the form of class discrimination, caste ostracism, and violence. The guiding principle of my theory rests upon the questions as to how the three stories position the female bodies at the margin of a discourse of a decolonized nation, how Devi’s stories narrate the protagonists’ feminist ideology and to what effect, and how Devi’s protagonists bring to the fore the mockery of nation-building led by the mainstream patriarchs who silenced and suppressed the gendered subalterns from the postcolonial national conversation

    Beef bone marrow has been part of the human diet since prehistoric times. Marrow bone stock is important culinary base used by gourmet chefs. It is well known for its distinct savory character in foods. While there has been a great deal published on flavor active components in cooked meats, the flavor composition of bone marrow is still relatively unstudied. For this study, commercial chopped fresh beef marrow bones were simmered in water for seven hours at 90ºC. Three batches of cooked marrow bone mixtures were prepared. First batch was not enzyme treated. The second and third batch was enzyme treated with papain and umamizyme and heated for one hour at 65ºC and 50ºC respectively. All three batches (untreated and enzyme treated) were defatted by microfiltration. Samples from all three batches were heated under pressure at 120ºC or 160ºC for one hour. In another series of experiments, the defatted stock samples of three batches (one untreated and two iii treated with papain or umamizyme) were heated for one hour with ribose, xylose or methyglyoxal. Head space volatiles of all above samples were analyzed using Ga
