Optimal Teleportation Based on Bell Measurement

We study optimal teleportation based on the Bell measurements. An explicit expression for the quantum channel associated with the optimal teleportation with an arbitrary mixed state resource is presented. The optimal transmission fidelity of the corresponding quantum channel is calculated and shown to be related to the fully entangled fraction of the quantum resource, rather than the singlet fraction as in the standard teleportation protocol.Comment: 7 pages, latex, no figure

A New Composite Restorative Based on a Hydrophobic Matrix

A hydrophobic restorative composite based on a fluorocarbon analog of an alkyl methacrylate and a bisphenol adduct was formulated into a one-paste system, which polymerized in the presence of blue light. Physical, mechanical, and water-related properties were determined. High contact angles and low water sorption were shown by the experimental composite. Capillary penetration of oral fluids around restorations, therefore, could be prevented in the presence of this highly hydrophobic surface. The physical and mechanical properties of the experimental composite were either comparable to or somewhat less favorable than commercial Bis-GMA composites.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67042/2/10.1177_00220345790580100401.pd

The Behavioral Roots of Information Systems Security:Exploring Key Factors Related to Unethical IT Use

Unethical information technology (IT) use, related to activities such as hacking, software piracy, phishing, and spoofing, has become a major security concern for individuals, organizations, and society in terms of the threat to information systems (IS) security. While there is a growing body of work on this phenomenon, we notice several gaps, limitations, and inconsistencies in the literature. In order to further understand this complex phenomenon and reconcile past findings, we conduct an exploratory study to uncover the nomological network of key constructs salient to this phenomenon, and the nature of their interrelationships. Using a scenario-based study of young adult participants, and both linear and nonlinear analyses, we uncover key nuances of this phenomenon of unethical IT use. We find that unethical IT use is a complex phenomenon, often characterized by nonlinear and idiosyncratic relationships between the constructs that capture it. Overall, ethical beliefs held by the individuals, along with economic, social, and technological considerations are found to be relevant to this phenomenon. In terms of practical implications, these results suggest that multiple interventions at various levels may be required to combat this growing threat to IS security

Deficiências de kacronutrientes e de boro em seringueira (Hevea brasiliensis L.)

In order to obtain: a) a clear picture of the deficiencies symptoms of N, P, K, Ca, Mg, S and B; b) the lack of the elements on the dry matter production; c) concentration of the macro and micronutrients on the leaves, stems and roots. Young rubber plants (Hevea brasiliensis L.), were cultivated in nutrients solutions, in which one the following elements were omitted at once: N, P, K, Ca, Mg, S and B. Clear out symptoms were obtained for all macronutrients and boron. The growth rate of the rubber plants were drastically affected by lack of N, K followed by other nutrients. The omission of P from the nutrient solution did not affected the growth of the plants. The levels detected by chemical analysis of the leaves from with symptoms of deficiency and without symptoms of deficiency plants were: N% = 1.94 and 3.40: P% =0.14 and 0.25; K% = 0.79 and 2.22; Ca% = 0.59 and 1.28; Mg% = 0.26 and 0.50; S% = 0.10 and 0.10; B ppm = 31-3 and 171.8.Plantas de seringueira (Hevea brasiliensis L.) foram cultivadas em casa de vegetação, em quartzo moído, irrigado com soluções nutritivas, e submetidas aos seguintes tratamentos: completo, omissão de N, omissão de P, omissão de Ca, omissão de Mg, omissão de S e omissão de B, com o objetivo de: (a) obter sintomas de deficiências de macronutrientes e de boro; (b) analisar o crescimento das plantas através da produção de matéria seca; (c) determinar a concentração de macro e micronutrientes nas folhas, caule e raízes das plantas cultivadas nos diversos tratamentos. Os sintomas visuais de deficiência foram identificados e descritos. As plantas foram coletadas e separadas em raiz, caule e folhas, e determinaram-se os teores de macro e micronutrientes . Os resultados mostraram: - foram identificados sintomas de deficiências para todos os tratamentos com omissão de nutrientes (N, P, K, Ca, Mg, S e B); - a omissão de N, K, Mg ou B da solução nutritiva diminuiu o crescimento das plantas; - as concentrações dos elementos nas folhas de plantas com sintomas e sem sintomas de deficiência foram, respectivamente: N% = 1,94 e 3,40; P% = 0,14 e 0,25; K% = 0,79 e 2,22; Ca% = 0,59e 1,28; Mg% = 0,26 e 0,50; S% = 0,10 e 0,10; Bppm = 31 ,3 e 171,8
