An analysis of the growth of young stands of western red cedar and associated species on the University of British Columbia research forest, Haney, British Columbia
Creators: name: Osborn, John Edward
Publisher: name: University of British Columbia
Year: 2011

description: Breast height radial growth of 165 western red cedar (Thuja plicata Donn), 14.5 western hemlock (Tsuga heterophylla (Raf.) Sarg.) and 33 Douglas fir trees (Pseudotsuga menziesii (Mirb.) Franco), in young natural stands on the eastern side of the University of British Columbia Research Forest near Haney, B.C. was analysed. Individual tree parameters measured included breast height diameter, total height, age at breast height, radial growth over last five and ten years, crown width, live crown length, tree class, live crown ratio, height/age ratio, crown width/breast height diameter ratio, and height/ crown width. Stand parameters measured were number of trees per plot, average breast height diameter of plot, and basal area per acre of plot. Plots were of variable radius as determined in prism cruising. Growth was investigated from results of simple correlation coefficients and several multiple regression analyses computed on an IBM 7040. Causes of variation in growth were assessed by studying interaction of variables affecting growth patterns. Individual species have distinctly different modes of growth. Species react differently to changes in stand density. Radial growth can be determined from measurements of tree crowns; and crown development reflects changes in stand density. Difference between species are found as crown development varies with stand density changes. Crown dimensions of western hemlock are least sensitive to changes in stand density as measured by basal area per acre, crown width/breast height diameter, live crown ratio, or height/crown width. An understanding of how crown dimensions change with variation in stand density can be used to refine predictions of tree radial growth derived from crown measurements.
Robustness of channel-adapted quantum error correction

Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A quantum channel models the interaction between the system we are interested in and its environment. Such a model can capture the main features of the interaction but because of the complexity of the environment we can not assume that it is fully accurate. We study the robustness of quantum error correction operations against completely unexpected and subsequently undetermined type of channel uncertainties. We find that a channel-adapted optimal error correction operation does not only give the best possible channel fidelity but it is more robust against channel alterations than any other error correction operation. Our results are valid for Pauli channels and stabilizer codes but based on some numerical results we believe that very similar conclusions can be drawn also in the general case.

Maailmas on näidatud noortel esineva kopsuvähi kasvutrendi. Eestis pole noorte täiskasvanute haigestumust pahaloomulistesse kasvajatesse süstemaatiliselt uuritud. Seetõttu oli töö eesmärk hinnata kopsuvähki haigestumust Eesti 15–44aastaste noorte hulgas ajavahemikul 1980–2009. Tuginedes Eesti vähiregistri andmetele, moodustas noortel diagnoositud kopsuvähk kõikidest kopsuvähi esmasjuhtudest 2%. Noortest kopsuvähki haigestunutest moodustasid suurema osa mehed (80%). Noorte naiste haigestumuskordajad on püsinud väiksena (0–2 juhtu 100 000 inimaasta kohta) ning vaadeldud ajaperioodil naiste haigestumuses muutusi ei ole toimunud.

Modeling thalamocortical cell: impact of Ca2+ channel distribution and cell geometry on firing pattern

Year: 2009
Subjects: subject: Neurons and Cognition (q-bio.NC)

description: The influence of calcium channel distribution and geometry of the thalamocortical cell upon its tonic firing and the low threshold spike (LTS) generation was studied in a 3-compartment model, which represents soma, proximal and distal dendrites as well as in multi-compartment model using the morphology of a real reconstructed neuron. Using an uniform distribution of Ca2+ channels, we determined the minimal number of low threshold voltage-activated calcium channels and their permeability required for the onset of LTS in response to a hyperpolarizing current pulse. In the 3-compartment model, we found that the channel distribution influences the firing pattern only in the range of 3% below the threshold value of total T-channel density. In the multi-compartmental model, the LTS could be generated by only 64% of unequally distributed T-channels compared to the minimal number of equally distributed T-channels. For a given channel density and injected current, the tonic firing frequency was found to be inversely proportional to the size of the cell. However, when the Ca2+ channel density was elevated in soma or proximal dendrites, then the amplitude of LTS response and burst spike frequencies were determined by the ratio of total to threshold number of T-channels in the cell for a specific geometry.

Kõige sagedasemaks günekoloogiliseks pahaloomuliseks kasvajaks on emakakaelavähk, millesse haigestumus on uuritud perioodil olnud olulise kasvutrendiga.

Publisher: name: Zenodo
Year: 2018

description: Background—Hereditary multiple exostoses (HME) is an inherited genetic condition, characterized bythe formation of multiple osteochondromas, developing throughout childhood and into puberty. Vascularcomplications associated with HME are uncommon.Methods—A case of a patient with HME who was admitted to hospital with subarachnoid hemorrhage(SAH), as a result of acute rupture of a basilar tip aneurysm (BTA), will be presented. Relevant literatureon this topic will be systematically reviewed.Results—We describe a rare case of a 48-year-old male patient presenting multiple exostoses in bothupper and lower limbs, with no familial history of such lesions. The patient experienced an episode of lossof consciousness, followed by tonal seizures, after a short (five-day) history of headache, proved finally tobe secondary to SAH due to rupture of a BTA. There was no antecedent of trauma, neck manipulation, orprevious infection. Aneurysm was successfully treated with the intravascular procedure (aneurysm occlusion with coil). Progressively, the patient recovered from dysphasia and tetraparesis, almost completely, following the appropriate treatment and rehabilitation program.In the systematic review, eight cases (including the one presented) of vertebrobasilar vascular system strokesecondary to solitary spinal osteochondroma or multiple osteochondromas were found, but only the presentcase was associated with basilar artery aneurysm.

We discuss the general features of the model, including its vacuum structure, theoretical and phenomenological constraints, and expectations for Higgs collider studies. The model predicts the existence of a pair of light charged scalars and, for vanishing triplet vacuum expectation value, contains a cold dark matter candidate. When the latter possibility occurs, the charged scalars are long-lived, leading to a prediction of distinctive single charged track with missing transverse energy or double charged track events at the LHC. The model predicts a significant excess of two-photon events compared to SM expectations due to the presence of a light charged scalar.

The Effect of Line of Sight Temperature Variation and Noise on Dust Continuum Observations

description: We investigate the effect of line of sight temperature variations and noise on two commonly used methods to determine dust properties from dust continuum observations of dense cores. One method employs a direct fit to a modified blackbody SED; the other involves a comparison of flux ratios to an analytical prediction. Fitting fluxes near the SED peak produces inaccurate temperature and dust spectral index estimates due to the line of sight temperature (and density) variations. Longer wavelength fluxes in the Rayleigh-Jeans part of the spectrum (>~ 600 micron for typical cores) may more accurately recover the spectral index, but both methods are very sensitive to noise. The temperature estimate approaches the density weighted temperature, or "column temperature," of the source as short wavelength fluxes are excluded. An inverse temperature - spectral index correlation naturally results from SED fitting, due to the inaccurate isothermal assumption, as well as noise uncertainties. We show that above some "threshold" temperature, the temperatures estimated through the flux ratio method can be highly inaccurate. In general, observations with widely separated wavelengths, and including shorter wavelengths, result in higher threshold temperatures; such observations thus allow for more accurate temperature estimates of sources with temperatures less than the threshold temperature. When only three fluxes are available, a constrained fit, where the spectral index is fixed, produces less scatter in the temperature estimate when compared to the estimate from the flux ratio method.

Effective metric Lagrangians from an underlying theory with two propagating degrees of freedom

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We describe an infinite-parametric class of effective metric Lagrangians that arise from an underlying theory with two propagating degrees of freedom. The Lagrangians start with the Einstein-Hilbert term, continue with the standard R^2, (Ricci)^2 terms, and in the next order contain (Riemann)^3 as well as on-shell vanishing terms. This is exactly the structure of the effective metric Lagrangian that renormalizes quantum gravity divergences at two-loops. This shows that the theory underlying the effective field theory of gravity may have no more degrees of freedom than is already contained in general relativity. We show that the reason why an effective metric theory may describe just two propagating degrees of freedom is that there exists a (non-local) field redefinition that maps an infinitely complicated effective metric Lagrangian to the usual Einstein-Hilbert one. We describe this map for our class of theories and, in particular, exhibit it explicitly for the (Riemann)^3 term.

Coronary artery intimal hyperplasia
Creators: name: Harmon, Thomas Peter
Publisher: name: University of British Columbia
Year: 2011

description: Intimal hyperplasia in the proximal portion of the right coronary artery was investigated by using longitudinal sections of the artery, to determine the amount of intimal and medial thickness, and the amount of deviation from the normal of the internal elastic lamina. One hundred and one samples in the 0-30 year age range were used and the results correlated with other known information about the individuals. Findings: 1. Intimal thickness increases directly as age increases. 2. There was a sex difference in the 16-30 year age group (males greater than females), but not under 15 years. 3. Intimal thickness increases significantly as the amount of internal elastic lamina change increases. 4. Medial thickness increases significantly with increasing age. 5. Intimal thickness increases significantly as medial thickness, heart mass and body mass increase, and increases at a more rapid rate than any of the three. 6. The amount of elastic lamina change increases significantly with age only between 1 and 30 years. These findings are correlated with the possible factors in the etiology of intimal hyperplasia.
Spectral Dimension of the Universe in Quantum Gravity at a Lifshitz Point

description: We extend the definition of "spectral dimension" (usually defined for fractal and lattice geometries) to theories on smooth spacetimes with anisotropic scaling. We show that in quantum gravity dominated by a Lifshitz point with dynamical critical exponent z in D+1 spacetime dimensions, the spectral dimension of spacetime is equal to d_s=1+D/z. In the case of gravity in 3+1 dimensions presented in arXiv:0901.3775, which is dominated by z=3 in the UV and flows to z=1 in the IR, the spectral dimension of spacetime flows from d_s=4 at large scales, to d_s=2 at short distances. Remarkably, this is the qualitative behavior of d_s found numerically by Ambjorn, Jurkiewicz and Loll in their causal dynamical triangulations approach to quantum gravity.

Screening of a Luttinger liquid wire by a scanning tunneling microscope tip: II. Transport properties

description: We study the effect of an electrostatic coupling between a scanning tunneling microscope tip and a Luttinger liquid wire on the tunneling current and noise between the two. Solving the Dyson equations non perturbatively for a local interaction potential, we derive the Green's functions associated to the wire and to the tip. Interestingly, the electrostatic coupling leads to the existence of new correlators, which we call mixed Green's functions, which are correlators between the bosonic fields of the wire and the tip. Next, we calculate the transport properties up to second order with the amplitude of the tunnel transfer: the tunnel current is strongly reduced by the presence of screening. The zero-frequency noise is modified in a similar way, but the Fano factor remains unchanged. We also consider the effect of the screening on the asymmetry of the finite-frequency non-symmetrized noise and on the conductance.
