Strange hadron production in pp, pPb and PbPb collisions at LHC energies

We present a systematic analysis of transverse momentum $(p_{T})$ spectra of the strange hadrons in different multiplicity events produced in pp collision at $\sqrt{s}$ = 7 TeV, pPb collision at $\sqrt{s_{NN}}$ = 5.02 TeV and PbPb collision at $\sqrt{s_{NN}}$ = 2.76 TeV. Both the single and differential freeze out scenarios of strange hadrons $K^0_s$, $\Lambda$ and $\Xi^-$ are considered while fitting using a Tsallis distribution which is modified to include transverse flow. The $p_{T}$ distributions of these hadrons in different systems are characterized in terms of the parameters namely, Tsallis temperature $(T)$, power $(n)$ and average transverse flow velocity $(\beta)$. It is found that for all the systems, transverse flow increases as we move from lower to higher multiplicity events. In the case of the differential freeze-out scenario, the degree of thermalization remains similar for events of different multiplicity classes in all the three systems. The Tsallis temperature increases with the mass of the hadrons and also increases with the event multiplicity in pp and pPb system but shows little variation with the multiplicity in PbPb system. In the case of the single freeze-out scenario, the difference between small systems (pp, pPb) and PbPb system becomes more evident. The high multiplicity PbPb events show higher degree of thermalization as compared to the events of pp and pPb systems. The trend of variation of the temperature in PbPb system with event multiplicity is opposite to what is found in the pp and pPb systems

Charged and Neutral Current Pion Production in Neutrino-Nucleus Scattering

In this article, we present the charged and neutral current coherent pion production in the neutrino-nucleus interaction in the resonance region using the formalism based on the partially conserved axial current (PCAC) theorem which relates the neutrino-nucleus cross section to the pion-nucleus elastic cross section. The pion nucleus elastic cross section is calculated using the Glauber model approach. We calculate the integrated cross sections for neutrino-carbon, neutrino-iron and neutrino-oxygen scattering. The results of integrated cross-section calculations are compared with the measured dataComment: XXII DAE High Energy Physics Symposium, Springer Proceedings in Physics 20

Ethanopharmacology of Myrica esculenta: A Systemic Review

This systematic review focuses on Myrica Esculenta, a medicinal plant with a rich history in traditional medicine. The aim of the review is to provide a comprehensive overview of the ethnopharmacology of the plant, including its traditional uses, phytochemistry and pharmacological benefits. Common uses of M. Esculenta include treating respiratory diseases such as asthma and bronchitis, as well as gastrointestinal problems such as diarrhea and ulcers. The plant is also used to treat fever, anemia and various ear, nose and throat diseases. With its recognition in the Ayurvedic Pharmacopoeia and its widespread use in folk medicine, M. Esculenta has significant ethnopharmacological value. Through phytochemical analysis, flavonoids, tannins, steroids and terpenes have been identified as the plant\u27s main components, which are believed to contribute to its medicinal properties such as analgesic, anti-inflammatory, antioxidant and anti-cancer effects. Pharmacological studies have confirmed the therapeutic potential of M. Esculenta and demonstrated its antiasthmatic, antiulcerative, anxiolytic, hepatoprotective and wound healing properties. Conservation measures are crucial to protect the plant from over-exploitation and habitat loss. Suggestions such as micropropagation, germplasm preservation and synthetic seed production make sense for sustainable use

Analysis of personality traits as a risk factor in crash related trauma

Background: Due to increasing stress, individual personality traits are becoming a significant contributor to CRT (Crash Related Trauma). In the present study, we hypothesized that there will be no difference in personality characteristics of CRT patients and control subjects and there will be no association between trauma and personality characteristics of CRT patients.Method: A total of 119 cases and 112 controls of age >18 years were selected as per criteria decided. After obtaining ethical clearance, patients presenting to the emergency orthopedic unit were included in the study. After primary management allenrolled subjects were assessed by ICD 10 module screening questionnaire and analyzed for nine personality traits, subject to written informed consent.Results: Of all the cases enrolled 82.35% were males. Impulsive personality trait is found in 84.78% (39/46) cases. There were 46 motorcyclists out of 119 cases enrolled. Most of the personality traits showed a statistical significant association (p < 0.0003) with CRT.Conclusion: Majority of CRT victims attending orthopedic emergency unit at trauma center had impulsive and histrionic personality characteristics which accounted for 84.78% and 82.61% cases respectively. These traits showed a statistical  significant association with CRT.Keywords: Crash related trauma, personality traits, motorcyclist.Due to errors in the previous PDF especially in the 'Cite as' authors names, the PDF fulltext has been reloaded.

Upotreba bezstanične matrice iz ošita bivola pri pupčanoj hernioplastici svinja.

Acellularization of xenogenic biomaterials has been highly desired for implantation without considerable adverse inflammatory and immune responses. Therefore, the present study was undertaken to acellularize the diaphragm of buffalo origin and to evaluate the effi cacy of this prepared acellular diaphragm matrix (ADM) scaffolds for the repair of umbilical hernia in pigs. Buffalo diaphragms were acellularized with different concentrations of sodium deoxycholate over a range of periods. Produced ADM scaffolds were used during umbilical hernioplasty in 12 crossbred Landrace pigs. Harvested serum samples on post-implantation days (0, 15 and 30) were subjected to sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) to observe serum protein distribution pattern. Treatment with 2 % sodium deoxycholate lead to complete acellularization of the bubaline diaphragm at 48 h. Microscopic examination of the detergent treated matrix confirmed complete extraction of stromal cells and orderly arranged collagen fibres. All the hernias repaired with ADM remained sound over a period of 3 months. The serum protein distribution on post-implantation day 15 was found different from day zero and becomes normal on day 30. All the hernias implanted with ADM healed completely without graft rejections. The present study suggested that 2 % sodium deoxycholate can be used for complete acellularization of bubaline diaphragm, and produced ADM may be used safely for umbilical hernioplasty in pigs.Bezstanična struktura ksenogenih biomaterijala smatra se povoljnom jer pri implantaciji ne uzrokuje upalne i imunološke reakcije. U ovom je istraživanju proveden postupak dobivanja bezstanične matrice iz ošita (BMO) bivola koji je zatim bio rabljen kao podloga za obnavljanje tkiva pri operaciji pupčane hernije svinja. Gubitak stanične strukture bivoljih ošita proveden je uz pomoć različitih koncentracija natrijeva deoksikolata, primijenjenih u određenim vremenskim razmacima. Proizvedene bezstanične matrice ošita upotrijebljene su pri pupčanoj hernioplastici kod 12 svinja križanaca landras pasmine. Uzorci seruma, prikupljeni 0., 15. i 30. dana nakon implantacije, bili su podvrgnuti natrijev dodecil sulfat-poliakrilamid gel elektroforezi (SDS-PAGE) s ciljem promatranja razdiobe serumskih proteina. Obrada 2 %-tnim natrijevim deoksikolatom dovela je do potpunog gubitka stanične strukture bivoljeg ošita za 48 sati. Mikroskopskim pregledom matrice obrađene detergentom potvrđeno je potpuno uklanjanje stanica strome te uredno raspoređena kolagena vlakna. Mjesta operacije svih hernija kod kojih je upotrijebljena bezstanična matrica ošita ostala su zdrava tijekom 3 mjeseca. Razdioba serumskih proteina 15 dana nakon implantacije bila je različita u odnosu na početni (0.) dan, a 30. dan nakon implantacije vratila se na normalu. Sve hernije operirane uz upotrebu BMO u potpunosti su zacijelile bez odbacivanja presatka. Pomoću 2 % natrijeva deoksikolata postiže se potpuni gubitak stanične strukture bivoljeg ošita koji se može sigurno primijeniti pri pupčanoj hernioplastici svinja

Benchmarking self-supervised video representation learning

Self-supervised learning is an effective way for label-free model pre-training, especially in the video domain where labeling is expensive. Existing self-supervised works in the video domain use varying experimental setups to demonstrate their effectiveness and comparison across approaches becomes challenging with no standard benchmark. In this work, we first provide a benchmark that enables a comparison of existing approaches on the same ground. Next, we study five different aspects of self-supervised learning important for videos; 1) dataset size, 2) complexity, 3) data distribution, 4) data noise, and, 5)feature analysis. To facilitate this study, we focus on seven different methods along with seven different network architectures and perform an extensive set of experiments on 5 different datasets with an evaluation of two different downstream tasks. We present several interesting insights from this study which span across different properties of pretraining and target datasets, pretext-tasks, and model architectures among others. We further put some of these insights to the real test and propose an approach that requires a limited amount of training data and outperforms existing state-of-the-art approaches which use 10x pretraining data. We believe this work will pave the way for researchers to a better understanding of self-supervised pretext tasks in video representation learning
