The hydrothermal synthesis, X-ray crystal structures and thermal and magnetic properties of a layered coordination polymer, [Ni(3.9)Mn(1.1)(μ(3)-OH)(2)(L(I))(2)(H(2)O)(10)]·2H(2)O (1) (L(I) = 1e,2a,4a,5e-cyclohexanetetracarboxylate), and a porous 3D coordination polymer, [Ni(4)(μ(2)-OH)(2)(μ(6)-H(2)L(IV))(2)(pymc)(4,4'-bpy)(H(2)O)(2)](OH)·9H(2)O (2) (pymc = 2-pyrimidinecarboxylate, 4,4'-bpy = 4...

O(N ) algorithms for N{body simulations enable the simulation of particle systems with up to 100 million particles on current Massively Parallel Processors (MPPs). Our optimization techniques mainly focus on minimizing the data movement through careful management of the data distribution and the data references, both between the memories of di erent nodes, and within the memory hierarchy of eac...

The study of Human immunodeficiency virus (HIV) in humans and animal models in last 31 years suggested that it is a causative agent of AIDS. This causes serious pandemic public health concern globally. It was reported that the HIV-1 reverse transcriptase (RT) played a critical role in the life cycle of HIV. Therefore, inhibition of HIV-1RT enzyme is one of the major and potential targets in the...

[1] We have reconstructed chronology for the disturbed bottom parts of the GRIP and GISP2 ice cores using the combined paleoatmospheric records of CH4 concentration and dOatm in the trapped gases. Our reconstructed ages for basal ice samples are based on comparison of published measurements of CH4 and d Oatm from the disturbed section of the GRIP and GISP2 cores with the same properties in the ...

Fifteen novel β-lactams bearing the N-ethyl tert-butyl carbamate group 5a-o and fifteen N-(2-aminoethyl) β-lactams 6a-o were synthesized by the ketene-imine [2+2] cycloaddition reaction (Staudinger ). The cycloaddition reaction was found to be totally diastereoselective leading exclusively to the formation of the cis-β-lactam derivatives. These newly synthesized β-lactams were evaluated for the...

Abstract Many recent palaeoclimatic studies have focused on Pleistocene interglacials, especially Marine Isotopic Stages (MIS) 5e and 11, as analogs to our modern interglacial (MIS 1). In continental area, archives allowing comparison between interglacials remain scarce. Calcareous tufa deposits, they are characteristic of these periods can provide long, almost continuous, records through their...

Marine Isotope Stage (MIS) 5e (130–116 ka) represents an important ‘process analogue’ for understanding the climatic feedbacks and responses likely active under future anthropogenic warming. Reconstructing Southern Ocean (SO) palaeoenvironment during MIS comparing it to present day provides insights into different of SO sectors a warmer climate. This study presents new records from seven marine...
