Numerical simulations of the Princeton magneto-rotational instability experiment with conducting axial boundaries

, 2016
We investigate numerically the Princeton magneto-rotational instability (MRI) experiment and the effect of conducting axial boundaries or endcaps. MRI is identified and found to reach a much higher saturation than for insulating endcaps. This is probably

Breather trapping and breather transmission in a DNA model with an interface [PDF]

, 2006
We study the dynamics of moving discrete breathers in an interfaced piecewise DNA molecule. This is a DNA chain in which all the base pairs are identical and there exists an interface such that the base pairs dipole moments at each side are oriented in

Convective overstability in accretion disks: 3D linear analysis and nonlinear saturation [PDF]

, 2014
Recently, Klahr & Hubbard (2014) claimed that a hydrodynamical linear overstability exists in protoplanetary disks, powered by buoyancy in the presence of thermal relaxation.

Electron Dephasing in Mesoscopic Metal Wires

, 2004
The low-temperature behavior of the electron phase coherence time, $\tau_{\phi}$, in mesoscopic metal wires has been a subject of controversy recently.

Relações entre os tipos e indicadores de acidez do solo em lavouras no sistema plantio direto na região do Planalto do Rio Grande do Sul Relationships among acidity types and indicators in soils under no-tillage system in the Rio Grande do Sul Planalto Region

Revista Brasileira de Ciência do Solo, 2008
A recente mudança no sistema de cultivo do solo ocorrida no Brasil, passando do preparo convencional (PC) para o sistema plantio direto (SPD), altera o funcionamento do solo. No solo cultivado no SPD, as relações se estabelecem no tempo e são preservadas

Reversal of Forest Soil Acidification in the Northeastern United States and Eastern Canada: Site and Soil Factors Contributing to Recovery

Soil Systems, 2020
As acidic deposition has decreased across Eastern North America, forest soils at some sites are beginning to show reversal of soil acidification. However, the degree of recovery appears to vary and is not fully explained by deposition declines alone.

Indicadores da acidez do solo para recomendação de calagem no sistema plantio direto Soil acidity indicators for liming in no-tillage systems

Revista Brasileira de Ciência do Solo, 2008
O tempo de cultivo do solo no sistema plantio direto (SPD) altera a magnitude das relações entre os componentes da acidez do solo e o rendimento das culturas. Altos rendimentos podem ser obtidos nesse sistema mesmo em áreas com alta acidez.

Dephasing of Electrons in Mesoscopic Metal Wires

, 2003
We have extracted the phase coherence time $\tau_{\phi}$ of electronic quasiparticles from the low field magnetoresistance of weakly disordered wires made of silver, copper and gold. In samples fabricated using our purest silver and gold sources, $\tau_{\

Induction in Saturation-Based Proof Search [PDF]

EasyChair Preprints, 2019
Many applications of theorem proving, for example program verification and analysis, require first-order reasoning with both quantifiers and theories such as arithmetic and datatypes. There is no complete procedure for reasoning in such theories but the state-of-the-art in automated theorem proving is still able to reason effectively with real-world ...
