Non-Markovianity of local dephasing channels and time-invariant discord

We study non-Markovianity and information flow for qubits experiencing local dephasing with an Ohmic class spectrum. We demonstrate the existence of a temperature-dependent critical value of the Ohmicity parameter s for the onset of non-Markovianity and give a physical interpretation of this phenomenon by linking it to the form of the reservoir spectrum. We demonstrate that this link holds also for more general spectra. We unveil a class of initial states for which discord is forever frozen at a positive value. We connect time invariant discord to non-Markovianity and propose a physical system in which it could be observed

Risk marker associations with venous thrombotic events: a cross-sectional analysis.

ObjectiveTo examine the interrelations among, and risk marker associations for, superficial and deep venous events-superficial venous thrombosis (SVT), deep venous thrombosis (DVT) and pulmonary embolism (PE).DesignCross-sectional analysis.SettingSan Diego, California, USA.Participants2404 men and women aged 40-79 years from four ethnic groups: non-Hispanic White, Hispanic, African-American and Asian. The study sample was drawn from current and former staff and employees of the University of California, San Diego and their spouses/significant others.Outcome measuresSuperficial and deep venous events, specifically SVT, DVT, PE and combined deep venous events (DVE) comprising DVT and PE.ResultsSignificant correlates on multivariable analysis were, for SVT: female sex, ethnicity (African-American=protective), lower educational attainment, immobility and family history of varicose veins. For DVT and DVE, significant correlates included: heavy smoking, immobility and family history of DVEs (borderline for DVE). For PE, significant predictors included immobility and, in contrast to DVT, blood pressure (BP, systolic or diastolic). In women, oestrogen use duration for hormone replacement therapy, in all and among oestrogen users, predicted PE and DVE, respectively.ConclusionsThese findings fortify evidence for known risk correlates/predictors for venous disease, such as family history, hormone use and immobility. New risk associations are shown. Striking among these is an association of PE, but not DVT, to elevated BP: we conjecture PE may serve as cause rather than consequence. Future studies should evaluate the temporal direction of this association. Oxidative stress and cell energy compromise are proposed to explain and predict many risk factors, operating through cell-death mediated triggering of coagulation activation

Two-qubit entanglement dynamics for two different non-Markovian environments

We study the time behavior of entanglement between two noninteracting qubits each immersed in its own environment for two different non-Markovian conditions: a high-$Q$ cavity slightly off-resonant with the qubit transition frequency and a nonperfect photonic band-gap, respectively. We find that revivals and retardation of entanglement loss may occur by adjusting the cavity-qubit detuning, in the first case, while partial entanglement trapping occurs in non-ideal photonic-band gap.Comment: 8 pages, 2 figure

The Impact of Compost Dose and SP36 Fertilizer Application on Soil Chemical Properties and Growth of Corn Plants (Zea mays L.) in Ultisol Soils

Ultisol soil has complex problems that result in low nutrient availability, especially P. This research aim was to determine the effect of the application of a mixture of compost and SP 36 fertilizer to increase the growth of corn plants on Ultisol soil. The research was conducted from October 17, 2017, to March 13, 2018. This research was conducted in the village of Aek Goti, Silangkit District, Labuhan Batu Selatan Regency, Sumatera Utara Province. The experimental method used was factorial Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor was a dose of compost in the form of Tithonia diversifolia and chicken manure with 4 levels of treatments (B0 : 0 ton/ha, B1: 10 tons/ha, B2: 20 tons/ha, B3: 30 tons/ha). Factor II was the dose of SP36 fertilizer with 3 treatments levels (P0: Control, P1: 100 kg SP36/ha, P2: 200 kg SP36/ha). The parameters observed were pH H2O, P Potential, Soil CEC, root dry weight (g), canopy dry weight (g) of corn (Zea mays L.). The results showed that the application of a mixture of compost Tithonia diversifolia and chicken manure at the rate of 30 tons/ha significantly increased pH H2O, P Potential, CEC, canopy dry weight, and root dry weight

Living Knowledge Production: Indigenous Approaches and Intersections in Higher Education

As educators and practitioners reflect on the relatively young lifespan of the United States higher education system, it is important to take this opportunity to explore and rethink our country’s systems of knowledge production. Currently many of the approaches within the United States rely heavily on Western European epistemologies. Through exploration of narrative and its influence on indigenous epistemologies, we hope to challenge and expand the Western emphasis on the empirical way of knowing. We will learn from the epistemologies of three indigenous communities: Hawaii, New Zealand, and the continental United States. We will examine the creation of worldviews, knowledge production, and the philosophy of Aloha

Growth and production response of mung bean (Vigna radiata L) by application of mycorriza and Penicillium sp in paddy lands

ABSTRACT  This study aimed to evaluate the effect of mycorrhiza and Penicilliumsp on the growth and production of mung beans in paddy land. The design of this experimental research was a factorial Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor was the dosage of mycorrhiza consisting of 0 g/plant; 5 g/plant; 10 g/plant; and 15g/plant. The second factor was the type of phosphate solubilizing microbes consisting of withoutPenicilliumsp; Penicilliumspfrom Mursala island (20 ml/plant); Penicilliumsp collection taken from soil biology laboratory of faculty of agriculture USU (20 ml/plant). The results showed that the dosage of Mycorrhiza and Penicilliumsp were not significantly affected the height of mung bean plants, however, it significantly affected the population of Penicillium sp. The application of 15 g Mycorrhiza with Penicilliumsp from Mursala was the best treatment for the growth of mungbean plants at 4 weeks after planting (42.98 cm) and the interaction of Mycorrhiza15 g/plant and PenicilliumspMursala produced the best seeds/plant of 16.76 g/plant.   REFERENCES  Adiningsih, S. 2004.
