Design by decay, decay by design
… and re-use as part of the design process. Decay, typically thought of as a destructive process with spatially and temporally unpredictable results can be potentially designed to high levels of spatial and temporal tunability, such that the product of decay can still be of value to the …

Beauty in decay
… complexes offer an aesthetic beauty in the decay of its materials and structures. American interest in agriculture as an investment in domestic self-reliance has waned over time leaving behind gigantic structures that are left to deteriorate without upkeep. The lack of upkeep causes a …

Topics in vacuum decay
… cosmological consequences. Some aspects of this decay are studied in this thesis. Solutions with different symmetry than the generically used O(4) symmetry are studied and their actions calculated. Vacuum decay in a spatial vector field is studied and novel features like kinky domain walls are …

Interactions Between Copper and Chlorine Disinfectants: Chlorine Decay, Chloramine Decay and Copper Pitting
… examined from the perspective of disinfectant decay and copper pitting corrosion. Sparingly soluble cupric hydroxide catalyzed the rapid decay of free chlorine, which in turn, led to production of less soluble and more crystalline phases of cupric hydroxide. The catalytic activity of the cupric …

The decay scheme of Kr⁸⁷
… spectroscopy were used to investigate the decay scheme of Kr⁸⁷. Natural krypton gas, containing 17 percent Kr⁸⁶, was irradiated in the 100 kilowatt V.P.I. research reactor to produce Kr⁸⁷ Which decays by beta emission to Rb⁸⁷. The halflife of Kr⁸⁷ was found to be 78 minutes in agreement …

Coherent decay of Bose-Einstein condensates
… that manifests itself as a collective decay of the assembly as a whole. As a signature of this phenomenon, there arises a complex chemical potential in which the imaginary part quantifies a coherent decay into collective phonon excitations of a collapsing ground state. The unique decay …

Non-Hermitian Perturbation Theory for the Electronic Decay of Excited and Ionized Molecules and Identification of the Electronic Decay Processes in the Auger Decay of Core-Ionized Xenon Fluorides
… by far not a matter of routine. The electronic decay of an excited molecule is investigated in terms of decay processes and the decay width is calculated in two ways with Wigner-Weisskopf theory and non-degenerate non-Hermitian Rayleigh-Schrödinger perturbation theory employing complex absorbing …

Post-Activation Potentiation: Decay or Fatigue Delay
<p>Post-activation potentiation has been shown to improve jumping performance and other ballistic activities. The improvements in performance have been attributed to four main mechanisms, but the most important mechanism to the current study is the improvement in neural activity that leads to …

Exponential Decay for the Saint-Venant Principle
We consider a semi-infinite beam B = {(z,t)(VBAR)z(ELEM)(OMEGA), t (GREATERTHEQ) 0} where (OMEGA) is a bounded domain in (//R)('2) with the cone property and a C('3)-smooth boundary. By applying semigroup theory and spectral theory, we show that in our formulation Saint-Venant's principle is true …

Multi-photon decay mode spectroscopy of positronium
… for the branching ratio of the four-photon decay of parapositronium (BR4γ) was measured using a multi-gamma-ray spectrometer. For the first time in such measurements, the spectrometer consisted of an array of eight identical LaBr3:Ce scintillator detectors, each of which combines good energy …

Duality, Weight Decay, and Metrized Deep Learning
… standard weight regularization methods—weight decay and spectral normalization—allowing models to reach equal performance with a lower Lipschitz bound. Leveraging that Muon’s update has a fixed spectral norm, we co-design a weight constraint method called spectral cap that improves the …

Study of Michel spectrum of tau decay
… to examine weak couplings through leptonic [tau] decay. I will use the ratio of Br... and Br... and the Michel parameters [rho] and [eta]. which describe the momenta spectrum of the daughter leptons. I studied using a simultaneous fit to the [tau] --> e and [tau] --> [mu] momentum spectra, using …

Collision induced decay of metastable baby skyrmions
… admit processes in which these solitons decay, violating standard model baryon number. We motivate the hypothesis that baryon-number-violating decay is a generic outcome of collisions between these heavy particles. We do so by exploring a 2+ 1 dimensional theory which also possesses …
