On the frecuency of simple somatic mutations
Genetic instability is a landmark of cancer, but simple patterns may be hidden behind it's complex evolution laws. This paper presents the results of analysing the distribution of mutations accross genes of the ICGC simple somatic mutations data.

Abstract:
The present experiment was designed to determine whether classical eyeblink conditioning (EBC) can be established under the conditions of using electrical microstimulation of hippocampus as the conditioned stimulus (CS) paired with airpuff unconditioned stimulus (US), to observe whether EBC transfer would occur when CSs shift between microstimulation of hippocampus as a CS (Hip-CS) and tone as a CS (tone CS), and to compare the difference in transfer effectiveness between delay EBC (dEBC) and trace EBC (tEBC). A total of 8 groups of guinea pigs, including 4 experimental groups and 4 control groups were included in the study. The experimental groups accepted Hip-CS (or tone CS) paired with US firstly; then, shifted CS to tone CS (or Hip-CS) and paired with US. The control groups accepted corresponding Hip-CS (or tone CS) and pseudo-paired with US, and then shifted to tone CS (or Hip-CS) and paired with US. Results show that EBC could be successfully established when using microstimulation of hippocampus as the CS pairing with airpuff US, and that acquisition rates of EBC were higher in experimental groups than in control groups after switching from Hip-CS to tone CS or vice versa, indicating the occurrence of learning transfer between EBC established with Hip-CS and tone CS. The present study also demonstrated that EBC acquisition rates were remarkably higher in dEBC than in tEBC in both transfer ways, suggesting that memory of CS–US association was less disturbed in dEBC than in tEBC by the sudden switch of CSs. The result is of significance to expand our knowledge about EBC transfer as well as the functional neural circuit underlying EBC transfer.

Resumos de Física
- ) A energia cinética é a energia associada ao movimento de um corpo, simbolizada por Ec, esta que será tanto maior quanto maior for a massa do corpo- m - e maior a sua velocidade- v - sendo definida pela expressão: \(Ec=\frac{1}{2}mv^2\) . E- jouls; m- kg (kilograma); v- m/s. * velocidade é igual à distancia a dividir por unidade de tempo*
- ) A energia potencial é a energia não associada ou movimento mas sim à potencialidade/possibilidade de o alterar devido a interações ( forças ). Existem vários exemplos de energia potencial:
- Energia potencial gravítica : há forças gravíticas entre corpos. exemplo: o sistema corpo Terra+Sol.
- Energia potencial elétrica: há forças elétricas entre corpos ou partículas com cargas elétricas. São importantes nas ligações químicas. exemplo: o sistema protão+eletrão.
- Energia potencial elástica: há forças elásticas entre corpos. exemplo: sistema mola+bola. *está na origem do movimento da bola e da mola quando se solta a bola *
Ec existe sempre que há movimento; Ep está associada a interações entre partes de um sistema.
- energia cinética das partículas do sistema.
- energia potencial, associada às interações entre essas partículas.
- da agitação corpuscular das partículas e portanto da temperatura do sistema ( quanto maior a sua agitação térmica implica maior ec que implica maior temperatura )
- do número de partículas do sistema ( quanto maior for a quantidade de matéria no sistema, maior será a sua energia interna ).
* se a temperatura de um sistema variar a agitação térmica das partículas também irá variar e consequentemente a energia cinética.*

When relatively stationary granular media experience stress they behave similarly to a solid. From our own experiences walking on piles of riverbed rocks, we know they rigidly resist external forces. One is able to walk without falling right through, and typically, without much difficulty. However, unlike in a true solid, the compressive force is not resisted uniformly. Instead, the force is transferred along chains of particles that rest on each other. We are interested in the properties of how these force chains propagate as a function of force threshold and compression, given by their packing fraction, and the sensitivity of these results to additive noise.
Probability Theory
Probability referes to a degree of confidence that an event of an uncertain nature will occur.
Space of possible outcomes Ω. Assume there is a set of measureable events S to which we are willing to assign probabilities. Each event α ∈ S is a subset of Ω. Probability theory requires that the event space satisfy 3 basic properties:
It contains the empty event ∅ and the trivial event Ω.
It’s closed under union.
It’s closed under complementation.
The requirements that the event space is closed under union and complementation emplies that it’s also closed under other Boolean operations.
