    Description: Author(s): Akihito Soeda, Paweł Kurzyński, Ravishankar Ramanathan, Kavan Modi, and Dagomir Kaszlikowski We investigate the set of qutrit states in terms of symmetric states of two qubits that violate the minimal contextual inequality, namely the Klyachko-Can-Binicoglu-Shumovsky (KCBS) inequality. The physical system that provides a natural framework for this problem is a biphoton, which consists of tw... [Phys. Rev. A 87, 022120] Published Mon Feb 25, 2013

    Description: Author(s): Lin Chen, Eric Chitambar, Kavan Modi, and Giovanni Vacanti We study various types of multipartite states lying near the quantum-classical boundary. The so-called classical states are precisely those in which each party can perfectly identify a locally held state without disturbing the global state, a task known as nondisruptive local state identification (N...

    Description: Polyaromatic hydrocarbons (PAHs) are prevalent, potent carcinogens, and 7,12-dimethylbenz[a]anthracene (DMBA) is a model PAH widely used to study tumorigenesis. Mice lacking Langerhans cells (LCs), a signatory epidermal dendritic cell (DC), are protected from cutaneous chemical carcinogenesis, independent of T cell immunity. Investigation of the underlying mechanism revealed that LC-deficient skin was relatively resistant to DMBA-induced DNA damage. LCs efficiently metabolized DMBA to DMBA-trans-3,4-diol, an intermediate proximal to oncogenic Hras mutation, and DMBA-treated LC-deficient skin contained significantly fewer Hras mutations. Moreover, DMBA-trans-3,4-diol application bypassed tumor resistance in LC-deficient mice. Additionally, the genotoxic impact of DMBA on human keratinocytes was significantly increased by prior incubation with human-derived LC. Thus, tissue-associated DC can enhance chemical carcinogenesis via PAH metabolism, highlighting the complex relation between immune cells and carcinogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3753811/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3753811/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Modi, Badri G -- Neustadter, Jason -- Binda, Elisa -- Lewis, Julia -- Filler, Renata B -- Roberts, Scott J -- Kwong, Bernice Y -- Reddy, Swapna -- Overton, John D -- Galan, Anjela -- Tigelaar, Robert -- Cai, Lining -- Fu, Peter -- Shlomchik, Mark -- Kaplan, Daniel H -- Hayday, Adrian -- Girardi, Michael -- 085780/Wellcome Trust/United Kingdom -- K08 AR002072/AR/NIAMS NIH HHS/ -- P30 CA016359/CA/NCI NIH HHS/ -- R01 AR056632/AR/NIAMS NIH HHS/ -- R01 CA102703/CA/NCI NIH HHS/ -- R01-AR044077/AR/NIAMS NIH HHS/ -- R01-AR056632/AR/NIAMS NIH HHS/ -- R01CA102703/CA/NCI NIH HHS/ -- T32 AR007016/AR/NIAMS NIH HHS/ -- Cancer Research UK/United Kingdom -- Department of Health/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Jan 6;335(6064):104-8. doi: 10.1126/science.1211600.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, Yale University School of Medicine, New Haven, CT 06520, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22223807" target="_blank"〉PubMed〈/a〉

    Description: Author(s): Kavan Modi, César A. Rodríguez-Rosario, and Alán Aspuru-Guzik The constraints imposed by the initial system-environment correlation can lead to nonpositive dynamical maps. We find the conditions for positivity and complete positivity of such dynamical maps by using the concept of an assignment map. Any initial system-environment correlations make the assignmen...

    Description: Author(s): Rosario Fazio, Kavan Modi, Saverio Pascazio, Vlatko Vedral, and Kazuya Yuasa We introduce a method to witness the quantumness of a system. The method relies on the fact that the anticommutator of two classical states is always positive. By contrast, we show that there is always a nonpositive anticommutator due to any two quantum states. We notice that interference depends on... [Phys. Rev. A 87, 052132] Published Thu May 23, 2013

    Description: Author(s): Laura Mazzola, César A. Rodríguez-Rosario, Kavan Modi, and Mauro Paternostro We analyze the role played by system-environment correlations in the emergence of non-Markovian dynamics. By working within the framework developed in Breuer et al. [ Phys. Rev. Lett. 103 210401 (2009) ], we unveil a fundamental connection between non-Markovian behavior and dynamics of system-enviro...
