Geometry of vanishing flow: a new probe to determine the in-medium nucleon nucleon cross-section

We study the transverse flow throughout the mass range from $^{20}Ne+^{20}Ne$ to $^{131}Xe+^{131}Xe$ as a function of the impact parameter. We find that at smaller impact parameters the flow is negative while going through the impact parameter, transverse flow vanishes at a particular colliding geometry named GVF. We find that the mass dependence of GVF is insensitive to the equation of state and momentum dependent interactions whereas it is quite sensitive to the cross section. So it can act as a useful tool to pin down the nucleon nucleon cross section

On the balance energy and nuclear dynamics in peripheral heavy-ion collisions

We present here the system size dependence of balance energy for semi-central and peripheral collisions using quantum molecular dynamics model. For this study, the reactions of $Ne^{20}+Ne^{20}$, $Ca^{40}+Ca^{40}$, $Ni^{58}+Ni^{58}$, $Nb^{93}+Nb^{93}$, $Xe^{131}+Xe^{131}$ and $Au^{197}+Au^{197}$ are simulated at different incident energies and impact parameters. A hard equation of state along with nucleon-nucleon cross-sections between 40 - 55 mb explains the data nicely. Interestingly, balance energy follows a power law $\propto{A^{\tau}}$ for the mass dependence at all colliding geometries. The power factor $\tau$ is close to -1/3 in central collisions whereas it is -2/3 for peripheral collisions suggesting stronger system size dependence at peripheral geometries. This also suggests that in the absence of momentum dependent interactions, Coulomb's interaction plays an exceedingly significant role. These results are further analyzed for nuclear dynamics at the balance point.Comment: 13 pages, 9 figures Accepted in IJMPE (in press

Isospin effects on the energy of vanishing flow in heavy-ion collisions

Using the isospin-dependent quantum molecular dynamics model we study the isospin effects on the disappearance of flow for the reactions of $^{58}Ni$ + $^{58}Ni$ and $^{58}Fe$ +$^{58}Fe$ as a function of impact parameter. We found good agreement between our calculations and experimentally measured energy of vanishing flow at all colliding geometries. Our calculations reproduce the experimental data within 5%(10%) at central (peripheral) geometries

Phytochemical analysis and screening of antibacterial activity of some selected Indian medicinal plants

Phytochemical screening and evaluation of antibacterial activity of ten plant species namely Aloe barbadensis, Aegel marmelos, Azadirachta indica, Bahunia variegate, Cannabis sativa, Emblica officinalis, Eugenia jambolana, Gmelina arborea, Nerium oleander and Vitex negundo have been carried out against six bacterial strains namely Escherichia coli 101, Escherichia coli 119, Micrococcus luteus, Bacillus subtilus, Bacillus cereus and Pseudomonas fluorescence. All the plants species taken in present study have shown the presence of tannin, flavonoids, terpenoids and alkaloids. Pholobatanins have found to be present in Aegel marmelos, Bahunia variegate and Eugenia jambolana while cardiac glycosides have been shown positive test on Aloe barbadensis, Azadirachta indica, Cannabis sativa, Nerium oleander and Vitex negundo. Methanol extract of Emblica officinalis have been shown significance potential against all test pathogens except Pseudomonas fluorescence followed by Nerium oleander, Azadirachta indica and Bahunia variegate

Rapidity distribution as a probe for elliptical flow at intermediate energies

Interplay between the spectator and participant matter in heavy-ion collisions is investigated within isospin dependent quantum molecular dynamics (IQMD) model in term of rapidity distribution of light charged particles. The effect of different types and size rapidity distributions is studied in elliptical flow. The elliptical flow patterns show important role of the nearby spectator matter on the participant zone. This role is further explained on the basis of passing time of the spectator and expansion time of the participant zone. The transition from the in-plane to out-of-plane is observed only when the mid-rapidity region is included in the rapidity bin, otherwise no transition occurs. The transition energy is found to be highly sensitive towards the size of the rapidity bin, while weakly on the type of the rapidity distribution. The theoretical results are also compared with the experimental findings and are found in good agreement.Comment: 8 figure

Editable AI: Mixed Human-AI Authoring of Code Patterns

Developers authoring HTML documents define elements following patterns which establish and reflect the visual structure of a document, such as making all images in a footer the same height by applying a class to each. To surface these patterns to developers and support developers in authoring consistent with these patterns, we propose a mixed human-AI technique for creating code patterns. Patterns are first learned from individual HTML documents through a decision tree, generating a representation which developers may view and edit. Code patterns are used to offer developers autocomplete suggestions, list examples, and flag violations. To evaluate our technique, we conducted a user study in which 24 participants wrote, edited, and corrected HTML documents. We found that our technique enabled developers to edit and correct documents more quickly and create, edit, and correct documents more successfully

Gender and the right to mobility in South Asia

"South Asia including Bangladesh, India, Nepal, Pakistan and Sri Lanka encompasses source, transit and destination areas for women who migrate for employment. In context of current migration patterns, this study identifies and analyzes sociopolitical restrictions on women s mobility; and highlights local, national and regional feminist perspectives, strategies and approaches to promote mobility, work and freedom from violence at all stages of migration. The strategies and tactics discussed in this report expand current discourses on migrant rights and provide insight that can inform local, national and regional policies and programmes to promote migrant rights. Part I provides a brief overview of migration patterns, delineates the many restrictions on women s mobility and underlines the spectrums of violence faced by migrant women. Violence in this context includes economic, physical and sexual violence. Part II documents the range of strategies used by South Asia Women s Fund (SAWF) partners. These social movement actors are committed to addressing all forms of migration related violence through an explicitly feminist, rights-based and regional approach. Key thematic areas of engagement include confronting defacto and dejure restrictions on women s right to mobility, right to work and right to information; and challenging social and policy practices that undermine and stigmatize women s work. Finally, the study concludes with thematic recommendations grounded in grassroots experience to inform partner strategies, SAWF funding priorities and future directions of rights-based anti-trafficking initiatives. These insights are relevant to recent global initiatives to address the impact of uneven economic growth within and among countries, including the United Nations Sustainable Development Agenda, Habitat III Urban Agenda and International Labour Organization deliberations on Decent work in global supply chains and Violence against women and men in the world of work.
