c_v2wuabijjmxr | (It would also be possible to add clauses to the formula to ensure that the three color classes are disjoint, but this makes no difference to the result.) Thus, by Courcelle's theorem, 3-colorability of graphs of bounded treewidth may be tested in linear time. For this variation of graph logic, Courcelle's theorem can ... | Courcelle's theorem |
c_8686exuwiyi1 | In one variation of the Gewald reaction a 3-acetyl-2-aminothiophene is synthesized starting from a dithiane (an adduct of sulfur and acetone if R = CH3 or acetaldehyde if R = H) and the sodium salt of cyanoacetone which in itself is very unstable: == References == | Gewald reaction |
c_sg5395igjbis | In one variation of the Reformatsky reaction an iodolactam is coupled with an aldehyde with triethylborane in toluene at -78 °C. | Reformatsky reaction |
c_8cj5ljzzojdd | In one variation the mechanism is thought to be as follows: The dichromate oxidizes the mercury, forming a layer of mercury oxide. In the process the dichromate is reduced to the chromium(III) ion. The oxidized layer on the mercury reduces the surface tension of the blob and the blob flattens out coming in contact with... | Mercury beating heart |
c_nxvlz48m93sy | Once there is no oxide coating left on the mercury blob, the surface tension increases and the blob rounds up and loses contact with the nail, ready to start the process over again. The net reaction is that the dichromate oxidizes the iron. This favorable reaction drives the mercury oxidations/reductions and the oscill... | Mercury beating heart |
c_s14qo2l40fpy | When the dichromate is fully reduced, the reaction stops. There may be other mechanisms involved, however. | Mercury beating heart |
c_7db61szuqlip | Lin et al. appear to report that the oscillations occur without the presence of the oxidizing agent, though the mercury does not appear to get an oxidizing layer on it and the oscillations are much weaker. An electrical double layer forms between the surface of the mercury droplet and the electrolyte solution. At rest ... | Mercury beating heart |
c_2n5z9s56kyt4 | In one variation, the falcon and hunter are introduced only through pawn promotion: a pawn promotes only to falcon or hunter.

c_it956l4bx2z7 | In one-dimensional field theory or quantum mechanics one defines as "instanton" a field configuration which is a solution of the classical (Newton-like) equation of motion with Euclidean time and finite Euclidean action. In the context of soliton theory the corresponding solution is known as a kink. In view of their an... | Instanton |
c_tj8z54m9a69r | The "instanton" (kink) solution is accompanied by another solution known as "anti-instanton" (anti-kink), and instanton and anti-instanton are distinguished by "topological charges" +1 and −1 respectively, but have the same Euclidean action. "Periodic instantons" are a generalization of instantons. In explicit form the... | Instanton |
c_tmv1myi1h4hn | In the limit of infinite period these periodic instantons – frequently known as "bounces", "bubbles" or the like – reduce to instantons. The stability of these pseudoclassical configurations can be investigated by expanding the Lagrangian defining the theory around the pseudoparticle configuration and then investigatin... | Instanton |
c_b5w3aezsvsjp | In one-host ticks the tick remains on the host through the larval, nymphal, and adult stages, only to leave the host to lay eggs. Eggs laid in the environment hatch into larvae, which immediately seek out a host in which to attach and feed. Fed larvae molt into unfed nymphs that remain on the host. After engorging on t... | Tick bites |
c_j03srfdspf1b | Once a female is both fed and ready to lay eggs, only then does she leave the host in search of a suitable area to deposit her eggs. Ticks that follow this life cycle are called one-host ticks. The winter tick Dermacentor albipictus and the cattle tick Boophilus microplus are examples of one-host ticks. | Tick bites |
c_yd4fl6l04506 | In one-male groups, the resident male is usually the sole breeder of the females and sires all the young. In multiple-male groups, the highest-ranking male fathers most of the offspring, followed by the next-ranking males and even outside males will father young. Higher-ranking females are more reproductively successfu... | Gray langur |
c_ffjjl4hu1fm5 | Females signal that they are ready to mate by shuddering the head, lowering the tail, and presenting their anogenital regions. Such solicitations do not always lead to copulation. | Gray langur |
c_vdz8wr6acmk6 | When langurs mate, they are sometimes disrupted by other group members. Females have even been recorded mounting other females.The gestation period of gray langur lasts around 200 days, at least at Jodhpur, India. In some areas, reproduction is year-around. | Gray langur |
c_tpwelo4z8ujy | Year-round reproduction appears to occur in populations that capitalize on human-made foods. Other populations have seasonal reproduction.Infanticide is common among gray langurs. Most infanticidal langurs are males that have recently immigrated to a group and driven out the prior male. | Gray langur |
c_pqa311su5rop | These males only kill infants that are not their own. Infanticide is more commonly reported in one-male groups, perhaps because one male monopolizing matings drives the evolution of this trait. In multiple-male groups, the costs for infanticidal males are likely to be high as the other males may protect the infants and... | Gray langur |
c_nqk7wopn7xba | Nevertheless, infanticide does occur in these groups, and is suggested that such practices serve to return a female to estrous and gain the opportunity to mate.Females usually give birth to a single infant, although twins do occur. Most births occur during the night. | Gray langur |
c_g6159tp9tnb2 | Infants are born with thin, dark brown or black hair and pale skin. Infants spend their first week attached to their mothers' chests and mostly just suckle or sleep. They do not move much in terms of locomotion for the first two weeks of their life. | Gray langur |
c_sceshj7m6dtr | As they approach their sixth week of life, infants vocalize more. They use squeaks and shrieks to communicate stress. In the following months, the infants are capable of quadrupedal locomotion and can walk, run and jump by the second and third months. | Gray langur |
c_pnmpz4ieaqwv | Alloparenting occurs among langurs, starting when the infants reach two years of age. The infant will be given to the other females of the group. However, if the mother dies, the infant usually follows. Langurs are weaned by 13 months. | Gray langur |
c_uky6xdrepqrq | In one-on-one, each player is assigned a color of puck (4 pucks per player). Play begins at one end of the table, and each player alternates shuffling one weight at a time down towards the opposite end of the table (which becomes the "scoring end" of the table), until all 8 pucks have been shuffled. Each player tries t... | Table shuffleboard |
c_j24c3lpkoeb6 | Play then continues from the other end of the table, where the pucks have come to rest. When a set number of points has been reached by a player (often 15 or 21), that player has won that "frame." A "match" consists of a predetermined number of frames. | Table shuffleboard |
c_nccn6jvqsxv4 | In one-step solution processing, a lead halide and a methylammonium halide can be dissolved in a solvent and spin coated onto a substrate.

c_4c2kbh90m58c | In only some cases is there direct interaction between the R gene product and the Avr gene product. For example, both FLS2 and XA21 interact with the microbial peptides. In contrast, for the NBS-LRR class of R genes, direct interaction has not been shown for most of the R/avr pairs. | Gene-for-gene relationship |
c_o9e48eg5kwgb | This lack of evidence for a direct interaction led to the formation of the guard hypothesis for the NBS-LRR class of R genes.This model proposes that the R proteins interact, or guard, a protein known as the guardee which is the target of the Avr protein. When it detects interference with the guardee protein, it activa... | Gene-for-gene relationship |
c_wngn133hds8b | The guardee protein is RIN4, which is hyperphosphorylated by the Avr proteins.
