Hydrodynamic simulations of shell convection in stellar cores

Shell convection driven by nuclear burning in a stellar core is a common hydrodynamic event in the evolution of many types of stars. We encounter and simulate this convection (i) in the helium core of a low-mass red giant during core helium flash leading to a dredge-down of protons across an entropy barrier, (ii) in a carbon-oxygen core of an intermediate-mass star during core carbon flash, and (iii) in the oxygen and carbon burning shell above the silicon-sulfur rich core of a massive star prior to supernova explosion. Our results, which were obtained with the hydrodynamics code HERAKLES, suggest that both entropy gradients and entropy barriers are less important for stellar structure than commonly assumed. Our simulations further reveal a new dynamic mixing process operating below the base of shell convection zones.Comment: 8 pages, 3 figures .. submitted to a proceedings of conference about "Red Giants as Probes of the Structure and Evolution of the Milky Way" which has taken place between 15-17 November 2010 in Rom

Pedestrian Trajectory Prediction with Structured Memory Hierarchies

This paper presents a novel framework for human trajectory prediction based on multimodal data (video and radar). Motivated by recent neuroscience discoveries, we propose incorporating a structured memory component in the human trajectory prediction pipeline to capture historical information to improve performance. We introduce structured LSTM cells for modelling the memory content hierarchically, preserving the spatiotemporal structure of the information and enabling us to capture both short-term and long-term context. We demonstrate how this architecture can be extended to integrate salient information from multiple modalities to automatically store and retrieve important information for decision making without any supervision. We evaluate the effectiveness of the proposed models on a novel multimodal dataset that we introduce, consisting of 40,000 pedestrian trajectories, acquired jointly from a radar system and a CCTV camera system installed in a public place. The performance is also evaluated on the publicly available New York Grand Central pedestrian database. In both settings, the proposed models demonstrate their capability to better anticipate future pedestrian motion compared to existing state of the art.Comment: To appear in ECML-PKDD 201

Spectrum of sputum culture isolates and their antibiotic susceptibility pattern in adult cancer patients receiving empirical antibiotics at Apeksha Hospital, Maharagama, Sri Lanka

Background: Infections are the second commonest cause of non-cancer deaths among patients with malignancies. Both lower respiratory tract infections (LRTI) and blood stream infections have shown near equal prevalence in these populations.Objective: To determine the spectrum and the antibiotic susceptibility pattern of the bacteria isolated from sputum of cancer patients receiving empirical antibiotics for LRTI at the time of the specimen collection.Methods: Fifty five patients who were diagnosed clinically and/or radiologically to have LRTIs were included in the study from May, 2018 to January, 2019 at Apeksha Hospital, Maharagama. Sputum culture was done and ABST was performed for isolated pathogens.Results: Klebsiella pneumoniae was the commonest pathogen (49.1%, 27/55) isolated followed by multi-drug resistant Acinetobacter spp. (16.4%, 9/55). Overall proportion of coliforms was found to be 63.6% (35/55). All the isolated Staphylococcus aureus (12.7%, 7/55) were methicillin-resistant (MRSA) and inducible clindamycin resistant was detected among three of those. Coliforms showed the highest sensitivity to amikacin (71.4%, 25/35) and gentamicin (68.6%, 24/35). Colistin was the only antibiotic detected sensitive against eight Acinetobacter baumannii /A. calcoaceticus isolates. One A. iwoffii isolate was resistant to all the tested antibiotics including colistin. Extended spectrum beta lactamase (ESBL) production was detected in 22.8% (8/35) and carbapenem resistance in 54.3% (19/35). Meropenem was the empirical antibiotic of choice in this patient population which had been given to 34.5% (19/55). The isolated pathogen in 54.5% (30/55) of the patients was resistant to the selected empirical antibiotic.Conclusion: Sputum culture isolates show a very high resistance to multiple antibiotics which results in limitations of appropriate empirical antibiotic selection.Acknowledgement: University of Sri Jayewardenepura, research grant No. ASP/MED/2017/36
