Abstract:

This thesis concerns critical branching random walks. We focus on supercritical (d ≥ 5 or higher) and critical (d=4) dimensions. In this thesis, we extend the potential theory for random walk to critical branching random walk. In supercritical dimensions, we introduce branching capacity for every finite subset of ℤ^d and construct its connections with critical branching random walk through the following three perspectives. 1. The visiting probability of a finite set by a critical branching random walk starting far away; 2. Branching recurrence and branching transience; 3. Local limit of branch

Abstract:

Rejecting approaches with a directionality parameter, mainstream minimalism has adopted the notion of strict (or unidirectional) branching. Within optimality theory however, constraints have recently been proposed that presuppose that the branching direction scheme is language specific. I show that a syntactic analysis of Chechen word order and relative clauses using strict branching and movement triggered by feature checking seems very unlikely, whereas a directionality approach works well. I argue in favor of a mixed directionality approach for Chechen, where the branching direction scheme d

Abstract:

Sherrington and co-workers have shown that branched vinyl polymers can be synthesized by the addition of a chain transfer agent to a conventional free radical statistical copolymerisation of a vinyl and a divinyl monomer. In the presence of the chain transfer agent, the molecular weight of the primary chains is reduced, gelation can be suppressed and soluble, branched polymers are obtained as the sole product. Living polymerisation techniques offer a way to control the primary chain length without the need for a transfer agent simply by adjusting the monomer/initiator molar ratio. It is sugges

In engineering, biology and physics, in many systems, the particles or members give birth and die through time. These systems can be modeled by continuoustime Markov Chains and Markov Processes. Applications of Markov Processes are investigated by many scientists, Jagers [1975] for example . In ordinary Markov branching processes, each particles or members are assumed to be identical and independent. However, in some cases, each two members of the species may interact/collide together to give new birth. In considering these cases, we need to have some more general processes. We may use collisi

This thesis concentrates on Branching Processes. We look at applying spine techniques and martingale changes of measure in order to first provide alternative proofs of well known discrete-time results concerning Branching Processes in Random Environments. We then apply the same ideas in a different setting to study Branching Brownian Motion with a Random Environment, focussing on the long-term spatial behaviour of the process. The final area of interest is Branching Brownian Motion with absorption at the origin, where we consider t he asymptotic behaviour of the survival probabilities near cri

Abstract:

The embryonic tracheal system of Drosophila melanogaster consists of a network of interconnected epithelial tubes of different size and architecture characterized by different cellular mechanisms of tube formation. The main branches of the Drosophila tracheal system have an extracellular lumen because their cells fold to form a tube. However, terminal cells (TCs), specialized cells designed to connect the tracheal system to target tissues, form unicellular branches by generating of a subcellular lumen. This topology of unicellular tubes is a good model to clarify the mechanisms that orchestrat

A two-dimensional numerical model for compressible branching flow through a slot is described for the purpose of predicting the discharge coefficients of film cooling holes in gas turbine blades.

An approximate method for calculating the compressible contraction coefficients is also discussed in the thesis.

Finite trace semantics then arises through an inductive construction in the Kleisli-category of the monad. We provide a more compreh

Abstract:

Axillary bud growth is inhibited by auxin produced at the shoot apex and transported down the stem. Removal of the shoot apex by decapitation can release buds from inhibition, and application of auxin to the cut stump can restore bud inhibition. However auxin action is likely to be indirect because auxin does not accumulate in inhibited buds, and therefore requires a second messenger. The max4 mutant of Arabidopsis has increased b,ud growth that leads to increased branching in mature plants.

For the case that a suitable partition has two rows, an explicit formula is then obtained for the Littlewood-Richardson coefficient using the Hook Length formula. All these result

We have found that the receptor regulated Smads (1, 2, 3, 5 and 8) as well as the common partner (Smad4), are expressed in the developing kidney during nephrogenesis. These factors have a specific

The main object of study in this thesis is branching Brownian motion, in which each particle moves like a Brownian motion and gives birth to new particles at some rate. In particular we are interested in where particles are located in this model at large times T : so, for a function f up to time T , we want to know how many particles have paths that look like f. Additive spine martingales are central to the study, and we also investigate some simple general properties of changes of measure related to such martingales.

There is a remarkable relationship between an organism's metabolic rate (resting power consumption) and the organism's mass. It may be a universal law of nature that an organism's resting metabolic rate is proportional to its mass to the power of 3/4. This relationship, known as Kleiber's Law, appears to be valid for both plants and animals. This law is important because it implies that larger organisms are more efficient than smaller organisms, and knowledge regarding metabolic rates are essential to a multitude of other fields in ecology and biology.
