title: Impact of Lower Limb Muscle Morphology on Sprint Performance
Creators: name: Cooper, Christopher M

Subjects: subject: sprint performance
subject: lower limb muscle morphology
subject: maximal velocity

description: The ability to rapidly accelerate and reach maximal sprinting velocity is paramount to success in running-based sports. However, there is a lack of scientific literature examining the muscular determinants of overground sprint acceleration and maximal velocity in athletes. The purpose of this study was to 1) identify the spatial patterns of lower limb muscle volumes and peak cross-sectional areas in sub-elite rugby league athletes who were affiliated with a National Rugby League (NRL) club; and 2) identify if spatial differences in normalised muscle volumes and peak cross-sectionals area were associated with 10-m sprint times, 30-m sprint times and peak sprint velocity. Nineteen male under-20 rugby league athletes (mean ± SD, age, 19.2 ± 0.7 years; height, 180.7 ± 5.6 cm; mass, 89.9 ± 10.0 kg) from a single NRL club, performed a series of 30-m sprints in order to derive 10-m sprint times, 30-m sprint times and peak sprint velocity. Magnetic Resonance (MR) imaging was used to calculate the normalised muscle volumes and peak cross-sectional areas of the gluteus maximus (GMAX), medius (GMED) and minimus (GMIN), tensor fascia latae (TFL), sartorius (SART), iliopsoas (ILIOP), gracilis (GR), adductor magnus, longus and brevis (ADD), rectus femoris (RF), vastus lateralis (VL), vastus intermedius (VI), vastus medialis (VM), semimembranosus (SM), semitendinosus (ST), biceps femoris long head (BFLH), biceps femoris short head (BFSH), soleus (SOL), gastrocnemius medialis (GM) and gastrocnemius lateralis (GL). Stepwise linear regression models were used to determine the extent to which sprint performance was explained by muscle morphology. The results revealed that variation in 10-m sprint times was best explained by ADD peak CSA (r2 = 0.582, p = 0.005) and TFL and VI normalised volume (r2 = 0.570, p = 0.026). Variation in 30-m sprint times were best explained by ADD, VI and VM peak CSA (r2 = 0.751, p = 0.030) and ILIOP and TFL normalised muscle volumes (r2 = 0.672, p = 0.021). Variation in peak sprint velocity was best explained by GMIN and GL peak CSA (r2 = 0.445, p = 0.029) and ILIOP, GL, RECF and ADD normalised muscle volume (r2 = 0.820, p = 0.035). The findings of this study demonstrate that sub-elite male rugby league athletes display non-uniform patterns of lower limb muscle size and suggest the possibility that preferential hypertrophy of the proximal hip- and knee-spanning muscles may have important implications for improving sprint acceleration and maximal velocity performance.

description: With a view to connecting random mutation on the molecular level to punctuated equilibrium behavior on the phenotype level, we propose a new model for biological evolution, which incorporates random mutation and natural selection. In this scheme the system evolves continuously into new configurations, yielding non-stationary behavior of the total fitness. Further, both the waiting time distribution of species and the avalanche size distribution display power-law behaviors with exponents close to two, which are consistent with the fossil data. These features are rather robust, indicating the key role of entropy.

description: We generalize Lévy's lemma, a concentration-of-measure result for the uniform probability distribution on high-dimensional spheres, to a much more general class of measures, so-called GAP measures. For any given density matrix $ρ$ on a separable Hilbert space $\mathcal{H}$, GAP$(ρ)$ is the most spread out probability measure on the unit sphere of $\mathcal{H}$ that has density matrix $ρ$ and thus forms the natural generalization of the uniform distribution. We prove concentration-of-measure whenever the largest eigenvalue $\|ρ\|$ of $ρ$ is small. We use this fact to generalize and improve well-known and important typicality results of quantum statistical mechanics to GAP measures, namely canonical typicality and dynamical typicality. Canonical typicality is the statement that for ``most'' pure states $ψ$ of a given ensemble, the reduced density matrix of a sufficiently small subsystem is very close to a $ψ$-independent matrix. Dynamical typicality is the statement that for any observable and any unitary time-evolution, for ``most'' pure states $ψ$ from a given ensemble the (coarse-grained) Born distribution of that observable in the time-evolved state $ψ_t$ is very close to a $ψ$-independent distribution. So far, canonical typicality and dynamical typicality were known for the uniform distribution on finite-dimensional spheres, corresponding to the micro-canonical ensemble, and for rather special mean-value ensembles. Our result shows that these typicality results hold also for GAP$(ρ)$, provided the density matrix $ρ$ has small eigenvalues. Since certain GAP measures are quantum analogs of the canonical ensemble of classical mechanics, our results can also be regarded as a version of equivalence of ensembles.

description: Computational modeling of the properties of crystalline materials has become an increasingly important aspect of materials research, consuming hundreds of millions of CPU-hours at scientific computing centres around the world each year, if not more. A routine operation in such calculations is the evaluation of integrals over the Brillouin zone. We have previously demonstrated that performing such integrals using generalized Monkhorst-Pack k-point grids can roughly double the speed of these calculations relative to the widely-used traditional Monkhorst-Pack grids, and such grids can be rapidly generated by querying a free, internet-accessible database of pre-generated grids. To facilitate the widespread use of generalized k-point grids, we present new algorithms that allow rapid generation of optimized generalized Monkhorst-Pack grids on the fly, an open-source library to facilitate their integration into external software packages, and an open-source implementation of the database tool that can be used offline. We also present benchmarks of the speed of our algorithms on structures randomly selected from the Inorganic Crystal Structure Database. For grids that correspond to a real-space supercell with at least 50 angstroms between lattice points, which is sufficient to converge density functional theory calculations within 1 meV/atom for nearly all materials, our algorithm finds optimized grids in an average of 0.19 seconds on a single processing core. For 100 angstroms between real-space lattice points, our algorithm finds optimal grids in less than 5 seconds on average.

description: We prove that for all $r\in \mathbb{N}\cup \{0\}$ and $s,t\in \mathbb{N}$, there exists $Ω=Ω(r,s,t)\in \mathbb{N}$ with the following property. Let $G$ be a graph and let $H$ be a subgraph of $G$ isomorphic to a $(\leq r)$-subdivision of $K_Ω$. Then either $G$ contains $K_t$ or $K_{t,t}$ as an induced subgraph, or there is an induced subgraph $J$ of $G$ isomorphic to a proper $(\leq r)$-subdivision of $K_s$ such that every branch vertex of $J$ is a branch vertex of $H$. This answers in the affirmative a question of Lozin and Razgon. In fact, we show that both the branch vertices and the paths corresponding to the subdivided edges between them can be preserved.

Using a random S-matrix theory approach, we derive the weak-localization correction, the magnitude of the conductance fluctuations, and the distribution of the conductance for three classes of reflection symmetry relevant for experimental ballistic microstructures. The S-matrix ensembles used fall within the general classification scheme introduced by Dyson, but because the conductance couples blocks of the S-matrix of different parity, the resulting conductance properties are highly non-trivial.

Reduction of Quantum Systems on Riemannian Manifolds with Symmetry and Application to Molecular Mechanics

description: This paper deals with a general method for the reduction of quantum systems with symmetry. For a Riemannian manifold M admitting a compact Lie group G as an isometry group, the quotient space Q = M/G is not a smooth manifold in general but stratified into a collection of smooth manifolds of various dimensions. If the action of the compact group G is free, M is made into a principal fiber bundle with structure group G. In this case, reduced quantum systems are set up as quantum systems on the associated vector bundles over Q = M/G. This idea of reduction fails, if the action of G on M is not free. However, the Peter-Weyl theorem works well for reducing quantum systems on M. When applied to the space of wave functions on M, the Peter-Weyl theorem provides the decomposition of the space of wave functions into spaces of equivariant functions on M, which are interpreted as Hilbert spaces for reduced quantum systems on Q. The concept of connection on a principal fiber bundle is generalized to be defined well on the stratified manifold M. Then the reduced Laplacian is well defined as a self-adjoint operator with the boundary conditions on singular sets of lower dimensions. Application to quantum molecular mechanics is also discussed in detail. In fact, the reduction of quantum systems studied in this paper stems from molecular mechanics. If one wishes to consider the molecule which is allowed to lie in a line when it is in motion, the reduction method presented in this paper works well.

description: We give examples of principal algebraic actions of the noncommutative free group $F$ of rank two, as well as other groups, by automorphisms of a connected compact abelian group for which there is an explicit measurable isomorphism to a Bernoulli action of the group. The isomorphism is defined using homoclinic points, a method that has been used earlier to construct symbolic covers of algebraic actions. To our knowledge, these are the first nontrivial examples of the Bernoullicity of an algebraic action of $F$.

Explorations of controted polycyclic aromatics as electronic materials
Creators: Wu, Ying
Publisher: name: Columbia University
Year: 2015
Subjects: Chemistry

description: This thesis describes the design, synthesis, characterization, and application of organic molecular materials made from strained polycyclic aromatic compounds. The strain in the molecular subunits induces non-planar structures. We coined the term “contorted aromatics” to describe these molecules. Contorted polycyclic aromatic hydrocarbons (PAHs) are not only structurally intriguing, but also promising small active molecules for organic electronic devices. This thesis explores the contorted PAHs in two directions, (1) making c-PAHs with high enantiomeric purity and (2) studying c-PAHs with expanded size, for desirable physical, chemical, and electronic properties. The synthesis and chiral resolution of trichloro c-hexabenzocorones (c-HBCs) stereoisomers in Chapter 2 enables the study of conversion barrier in expanded aromatic systems with adjacent cove-units. We also rationalized the formation of thermodynamic stereoisomers and kinetically trapped stereoisomers with density functional theory (DFT) calculations. The organic film effect transistors (OFETs) fabricating from racemic trichloro c-HBC are photo-responsive, suggesting enantiopure OFETs may have potential application in detecting polarized light. Chapter 3 describes the expeditious synthesis of a supersized contorted aromatic molecule, c-octabenzocircumbiphenyl (c-OBCB). Spectroscopic and cyclic voltammetry characterizations show that c-OBCB has a smaller band-gap relative to its analog c-HBCs as designed. The expanded contorted shape results in strong association of c-OBCB with shape-complementary PC70BM fullerenes, as demonstrated by NMR and fluorescence spectroscopies. Chapter 4 studies c-OBCB as an active component in OFETs and solar cells. The tetradodecyloxy-substituted c-OBCB self-assembles to form the active layer in OFETs. Transistor characteristics show that c-OBCBs transport holes readily in thin films. Bulk hetero-junction (BHJ) solar cells of c-OBCB: PC70BM fullerene improved solar power conversion efficiency to 2.88%. External quantum efficiency (EQE) spectra reveal that the red-shift in absorbance is responsible for the higher PCE for c-OBCB compared to the smaller c-HBC series, which charts a clear path to improving the properties of these materials in OPVs by further red-shifting the absorbance. Chapter 5 describes the selective dispersion of single-walled carbon nanotubes (SWCNTs) using c-OBCB. Our dispersion of SWCNTs with c-OBCB selectively disperses semiconducting SWCNTs in toluene with high purity, enabling direct film process with a simple filtration method. We fabricate SWCNTs network transistors using the sorted semiconducting SWCNTs. Our method demonstrates the use of small molecules for facile sorting of semiconducting SWCNTs in high purity (97%) and subsequent direct transistor fabrication from the dispersion.

description: This study presents results on detecting neutral atomic hydrogen (HI) 21cm absorption in the spectrum of PKS1413+135 at redshift $z=0.24670041$. The observation was conducted by FAST, with a spectral resolution of 10 Hz, using 10 minutes of observing time. The global spectral profile is examined by modeling the absorption line using a single Gaussian function with a resolution of 10 kHz within a 2 MHz bandwidth. The goal is to determine the rate of the latest cosmic acceleration by directly measuring redshift evolution of H I 21 cm absorption line with Hubble flow towards a same background Quasar over a decade or longer time span. This will serve as a detectable signal generated by the accelerated expansion of the Universe at redshift $z < 1$, referred to as redshift drift $\dot{z}$ or the SL effect. The measured HI gas column density in this DLA system is approximately equivalent to the initial observation value, considering uncertainties of the spin temperature of a spiral host galaxy. The high signal-to-noise ratio of 57, obtained at a 10 kHz resolution, strongly supports the feasibility of using the H I 21 cm absorption line in DLA systems to accurately measure the redshift drift rate at a precision level of around $10^{-10}$ per decade.

description: We consider pairs of automorphisms $(ϕ,σ)$ acting on fields of Laurent or Puiseux series: pairs of shift operators $(ϕ\colon x\mapsto x+h_1, σ\colon x\mapsto x+h_2)$, of $q$-difference operators $(ϕ\colon x\mapsto q_1x,\ σ\colon x\mapsto q_2x)$, and of Mahler operators $(ϕ\colon x\mapsto x^{p_1},\ σ\colon x\mapsto x^{p_2})$. Given a solution $f$ to a linear $ϕ$-equation and a solution $g$ to a linear $σ$-equation, both transcendental, we show that $f$ and $g$ are algebraically independent over the field of rational functions, assuming that the corresponding parameters are sufficiently independent. As a consequence, we settle a conjecture about Mahler functions put forward by Loxton and van der Poorten in 1987. We also give an application to the algebraic independence of $q$-hypergeometric functions. Our approach provides a general strategy to study this kind of question and is based on a suitable Galois theory: the $σ$-Galois theory of linear $ϕ$-equations.

description: In NMR-based quantum computing, it is known that the controlled-NOT gate can be implemented by applying a low-power, monochromatic radio-frequency field to one peak of a doublet in a weakly-coupled two-spin system. This is known in NMR spectroscopy as Pound-Overhauser double resonance. The ``transition'' Hamiltonian that has been associated with this procedure is however only an approximation, which ignores off-resonance effects and does not correctly predict the associated phase factors. In this paper, the exact effective Hamiltonian for evolution of the spins' state in a rotating frame is derived, both under irradiation of a single peak (on-transition) as well as between the peaks of the doublet (on-resonance). The accuracy of these effective Hamiltonians is validated by comparing the observable product operator components of the density matrix obtained by simulation to those obtained by fitting the corresponding experiments. It is further shown how both the on-transition and on-resonance fields can be used to implement the controlled-NOT gate exactly up to conditional phases, and analytic expressions for these phases are derived. In Appendices, the on-resonance Hamiltonian is analytically diagonalized, and proofs are given that, in the weak-coupling approximation, off-resonance effects can be neglected whenever the radio-frequency field power is small compared to the difference in resonance frequencies of the two spins.

description: Imagine being shown $N$ samples of random variables drawn independently from the same distribution. What can you say about the distribution? In general, of course, the answer is nothing, unless we have some prior notions about what to expect. From a Bayesian point of view we need an {\it a priori} distribution on the space of possible probability distributions, which defines a scalar field theory. In one dimension, free field theory with a constraint provides a tractable formulation of the problem, and we also discus generalizations to higher dimensions.

Psychiatric hospitals--Outpatient services

description: Two related program evaluations of the mental health system in Puerto Rico are conducted. Initially, research is carried out in two state psychiatric hospitals involving an organizational analysis of relevant systems variables as they impinge upon effective institutional functioning. In this scheme hospital effectiveness is predicted by success in achieving formally prescribed goals and in the adequacy of resource utilization. The basic assumption is that the psychiatric hospital reflects the patterning of reciprocal and interdependent behaviors of individuals which form a larger all-important pattern. The hospitals are studied by means of a questionnaire administered to staff to ascertain perceptions of the work environment, communication and coordination processes, overall hospital organization, and the treatment environment.

The results of organizational functioning are presented in a profile analysis plotting institutional means over ten functional dimensions. Individual component variables are converted into standard scores and broken down by staff sub-groups. Each institution and staff sub-group differs uniquely across the dimensions. Overall the results point to excessive staff frustration and disillusionment with the organization's functions, and a treatment environment limited in patient autonomy, socio-emotional interaction, and therapeutic content.

The complementary study of first releases from these hospitals examines background and performance characteristics of a sample of patients in an effort to distinguish those who complied with aftercare referrals from those who did not, and those who were readmitted from those still in the community one year after release.

Bivariate analysis of the relationship between each of the two dependent variables and the several demographic and treatment variables at each hospital reveals that the strongest differentiation of compliers from non-compliers is having been active in pre-hospital outpatient care, while the extent of use of aftercare was the strongest predictor of remaining in the community.

Implications for policy and for further research in mental health service delivery are discussed.

description: This is the first of a pair of papers devoted to the local invariants of Goursat distributions. The study of these distributions naturally leads to a tower of spaces over an arbitrary surface, called the monster tower, and thence to connections with the topic of singularities of curves on surfaces. Here we study those invariants of Goursat distributions akin to those of curves on surfaces, which we call structural invariants. In the subsequent paper we will relate these structural invariants to the small growth invariants.

description: Our first collection of results parametrize (filtered) actions of a quantum Borel $U_q(\mathfrak{b}) \subset U_q(\mathfrak{sl}_2)$ on the path algebra of an arbitrary (finite) quiver. When $q$ is a root of unity, we give necessary and sufficient conditions for these actions to factor through corresponding finite-dimensional quotients, generalized Taft algebras $T(r,n)$ and small quantum groups $U_q(\mathfrak{sl}_2)$.
 In the second part of the paper, we shift to the language of tensor categories. Here we consider a quiver path algebra equipped with an action of a Hopf algebra $H$ to be a tensor algebra in the tensor category of representations $H$. Such a tensor algebra is generated by an algebra and bimodule in this tensor category. Our second collection of results describe the corresponding bimodule categories via an equivalence with categories of representations of certain explicitly described quivers with relations.

description: This paper presents a theoretical study on the production of the heavy-flavour decay lepton (HFL) in high-energy nuclear collisions at the LHC. The pp-baseline is calculated by the FONLL program, which matches the next-to-leading order pQCD calculation with the next-to-leading-log large-$p_T$ resummation. The in-medium propagation of heavy quarks is driven by the modified Langevin equations, which consider both the elastic and inelastic partonic interactions. We propose a method to separate the respective influence of the six factors, such as pp-spectra, the cold nuclear matter (CNM) effects, in-medium energy loss (E-loss), fragmentation functions (FFs), coalescence (Coal), and decay channels, which may contribute to the larger $R_{AA}$ of HFL $\leftarrow b$ compared to that of HFL $\leftarrow c$ in nucleus-nucleus collisions. Based on quantitative analysis, we demonstrate that both coalescence hadronization, decay channels and the mass-dependent E-loss play an essential role at $p_T<5$ GeV, while the latter dominates the higher $p_T$ region. It is also found that the influences of the CNM effects and FFs are insignificant. At the same time, different initial pp-spectra of charm and bottom quarks have a considerable impact at $p_T>5$ GeV. Furthermore, we explore the path-length dependence of jet quenching by comparing the HFL $R_{AA}$ in two different collision systems. Our investigations show smaller HFL $R_{AA}$ in Pb+Pb than in Xe+Xe within the same centrality bin, consistent with the ALICE data. The longer propagation time and more effective energy loss of heavy quarks in Pb+Pb collisions play critical roles in the stronger yield suppression of the HFL compared to that in Xe+Xe. In addition, we observe a scaling behavior of the HFL $R_{AA}$ in Xe+Xe and Pb+Pb collisions.

description: Context. The evolution of massive stars is strongly influenced by internal mixing processes such as semiconvection, convective core overshooting, and rotationally induced mixing. None of these is currently well constrained. Aims. We investigate models for massive stars in the Small Magellanic Cloud (SMC). We aim to constrain the various mixing efficiencies by comparing model results to observations. Methods. We use the stellar evolution code MESA to compute more than 60 grids of detailed evolutionary models for stars with initial masses of 9 to 100 Msol, in each grid assuming different combinations of mixing efficiencies. Results. We find that for most of the combinations of the mixing efficiencies, models in a wide mass range spend core-helium burning either only as blue supergiants, or only as red supergiants. The latter case corresponds to models that maintain a shallow slope of the hydrogen/helium (H/He) gradient separating the core and the envelope of the models. Only a small part of the mixing parameter space leads to models that produce a significant number of blue and red supergiants, which both exist abundantly in the SMC. Interestingly, these models contain steep H/He gradients, as is required to understand the hot, hydrogen-rich Wolf-Rayet stars in the SMC. We find that unless it is very fast, rotation has a limited effect on the H/He profiles in our models. Conclusions. While we use specific implementations of the considered mixing processes, they comprehensively probe the two first order structural parameters: the core mass and the H/He gradient in the core-envelope interface. Our results imply that, in massive stars, the H/He gradients above the helium cores become very steep. Our model grids can be tested with future observational surveys of the massive stars in the SMC, and thereby help to considerably reduce the uncertainties in models of massive star evolution.

Exploration of Novel Applications for Optical Communications using Silicon Nanophotonics

description: Silicon photonics is considered to have the potential to enable future communication systems with optical input-outputs to circumvent the shortcomings of electronics. Today silicon is the material of choice for photonic and optoelectronic circuits, mainly due to its excellent material properties, established processing technology, low-cost, compact device footprint, and high-density integration. From sensing and detection to computing and communications, silicon photonics has advanced remarkably in the last couple of decades and found numerous applications.
      This thesis work focusses on three novel applications of silicon photonics for optical communications. The first application is the design and demonstration of a differential phase shift keying (DPSK) demodulator circuit using a ring resonator. DPSK-based transceivers are being actively considered for short-haul optical communication systems due to their advantages in terms of high extinction ratio, dispersion tolerance, and improved sensitivity. The ring resonator utilizes the concept of coherent perfect absorption and results into a compact demodulator circuit that can be easily integrated into an all-optical system. The next application involves a nonlinear optical process, namely, four wave mixing (FWM) inside a silicon nanowire. For FWM to occur efficiently, phase matching between the real propagation constants of all the frequency components is a key requirement. However, this condition cannot be easily satisfied in integrated optics semiconductor platforms. We propose an altogether new approach to achieve signal gain within the context of non-Hermitian photonics and parity-time (PT) symmetry and show that the phase matching criterion is not necessary to achieve efficient nonlinear interactions. Instead by introducing losses only to the idler components while leaving the pump and signal waves intact, we analyze a coupled-wave system of silicon nanowires using finite difference time domain technique and find that signal gain is indeed possible in such a system, irrespective of the fulfillment of the phase-matching condition. The final application of silicon photonics in this thesis is the engineering of zero group velocity dispersion (GVD) point in the C-band of communication channel. The problem of pulse broadening due to chromatic dispersion is becoming an increasingly important factor for signal degradation. We propose a hybrid silicon/plasmonic waveguide that can change the zero-GVD point by altering the geometry and material of the waveguide components. In addition, such hybrid system also has the potential to transmit both optical and electronic signals along the same circuitry.

description: We formulate a scaling theory for the long-time diffusive motion in a space occluded by a high density of moving obstacles in dimensions 1, 2 and 3. Our tracers diffuse anomalously over many decades in time, before reaching a diffusive steady state with an effective diffusion constant $D_\mathrm{eff}$, which depends on the obstacle diffusivity and density. The scaling of $D_\mathrm{eff}$, above and below a critical regime, is characterized by two independent critical parameters: the conductivity exponent $μ$, also found in models with frozen obstacles, and an exponent $ψ$, which quantifies the effect of obstacle diffusivity.

description: This study aims to explore the impact the Olympic games has on participation rates in sporting clubs and the impact that this four year cycle has on participation rates in schools across Western Australia. The data was collected from, Swimming Western Australia, Athletics West and Independent school in Western Australia. In this study there is a trend analysing the increase of participation rates in sporting clubs after the Olympics every four years from 2015 to  2024. The data is categorised yearly participation rates from Swimming Western Australia (WA), Athletics West. As well as the impact the Olympics has on Independent schools participation in swimming and athletics. These results indicate that there is a four-year cycle impacting sporting clubs’ for both swimming and athletics participation. Likewise there is a  correlation impacting positively on Independent schools. This study also serves as a guide to make recommendations that schools consider adapting programs with the potential to see greater participation co-synced with the four year Olympics cycle.
