Recombination and peak jumping

We show that genetic recombination can be a powerful mechanism for escaping suboptimal peaks. Recent studies of empirical fitness landscapes reveal complex gene interactions and multiple peaks. However, classical work on recombination largely ignores the effect of complex gene interactions. Briefly, we restrict to fitness landscapes where the global peak is difficult to access. If the optimal g...

Peak-Jumping Frequent Itemset Mining Algorithms

We analyze algorithms that, under the right circumstances, permit efficient mining for frequent itemsets in data with tall peaks (large frequent itemsets). We develop a family of level-by-level peak-jumping algorithms, and study them using a simple probability model. The analysis clarifies why the jumping idea sometimes works well, and which properties the data needs to have for this to be the ...

Jumping and Non-Jumping Genes

The term ‘horizontal transfer (HT)’ refers to the transfer of genetic material between two reproductively isolated organisms. HT is thought to occur rarely in eukaryotes compared to vertical inheritance, the transmission of DNA from parent to offspring. In a recent study we have provided evidence that a family of DNA transposons, called SPACE INVADERS or SPIN, independently invaded horizontally...

Dielectronic recombination for aluminum-like iron peak elements

DR is an atomic physics process important for accurately modeling astrophysical plasmas. DR is the dominant electron-ion recombination process for most ions in both photoionized and collisionally-ionized plasmas and plays a central role in determining the charge state balance and spectra of these plasmas. Over the past few years, our group has computed DR and RR data for H through Zn for all is...

Photodissociation and recombination of solvated I 2 2 : What causes the transient absorption peak ?

Seven years ago, Lineberger and co-workers observed evidence of coherent nuclear motion in the photodissociation and recombination of I2 2 clustered with CO2 . 1–3 In their experiment, a 720 nm pulse excites the I2 2 chromophore to its repulsive A8 state ~Fig. 1!. Dissociation of the chromophore makes the cluster transparent, allowing recombination to be monitored with a subsequent 720 nm probe...
