The well-known 1-2-3 Conjecture addressed by Karoński, Luczak and Thomason asks whether the edges of every undirected graph G with no isolated edge can be assigned weights from {1, 2, 3} so that the sum of incident weights at each vertex yields a proper vertex-colouring of G. In this work, we consider a similar problem for oriented graphs. We show that the arcs of every oriented graph − → G can...

Inspired by the ability of lotus leaves to repel water, super hydrophobic coatings are engineered and used reduce drag. The prospect drag reduction depends on surface geometry flow conditions. In this work, we suggest a new mechanism incorporating resistance induced inside lubricating layer which could be responsible for decrease drag-reduction performance in laminar regime. A simple model comb...

Bioassay cages are commonly used to assess efficacy of insecticides against adult mosquitoes in the field. To correlate adult mortality readings to insecticidal efficacy and/or spray application parameters properly, it is important to know how the cage used in the bioassay interacts with the spray cloud containing the applied insecticide. This study compared the size of droplets, wind speed, an...

Nogo receptor-1 (NgR1) and its ligands inhibit neuronal plasticity and limit functional recovery after brain damage such as ischemic stroke. We have previously shown that lateral olfactory tract usher substance (LOTUS) antagonizes NgR1-mediated signaling. Here, we investigated whether LOTUS enhances neuronal plasticity and functional recovery after brain focal ischemia in adult mice. Focal isch...

Neural circuitry formation depends on the molecular control of axonal projection during development. By screening with fluorophore-assisted light inactivation in the developing mouse brain, we identified cartilage acidic protein-1B as a key molecule for lateral olfactory tract (LOT) formation and named it LOT usher substance (LOTUS). We further identified Nogo receptor-1 (NgR1) as a LOTUS-bindi...

We report development of the first genetically encoded bioluminescent indicator for membrane voltage called LOTUS-V. Since it is bioluminescent, imaging LOTUS-V does not require external light illumination. This allows bidirectional optogenetic control of cellular activity triggered by Channelrhodopsin2 and Halorhodopsin during voltage imaging. The other advantage of LOTUS-V is the robustness o...

We reconsider the well-known conditions which guarantee roots of a third-degree polynomial to be inside unit circle. These are important in stability analysis equilibria a...

Climate change and unstable earth’s crust are effecting the overall environment. Oceans are one environmental component that has been shown to be heavily affected by those factors. One example would be the melting of the North Pole, which is affecting the temperature of the overall ocean such as the Atlantic Ocean. Another example would be the recent instability of the earth’s crust in the ocea...

Graph conditions are a means to express structural properties for graph transformation systems and graph programs in a large variety of application areas. With HR∗ graph conditions, non-local graph properties like “there exists a path of arbitrary length” or “the graph is circle-free” can be expressed. We show, by induction over the structure of formulas and conditions, that (1) any node-counti...

Birdsfoot trefoil (Lotus corniculatus) increases milk yield of dairy cows. An indoor feeding experiment using Friesian dairy cows in mid lactation was conducted to determine what proportions of the milk yield and composition changes were due to the condensed tannins (CT) in Lotus, and what proportions were due to factors associated with legumes (higher herbage intake and forage quality). Cows w...
