description: Nemoura lazoensis sp. n. (Figs. 32-37) Material examined. Holotype ♂, pharate paratype ♂, RUSSIA, Primorje, little spring seeps on the banks of Lazovska reka ca 50 km W of Lazo * 43°28'N, 133°44'E +, 13.6.1998, leg. P. Zwick. Some larvae taken together with the males are probably conspecific. Presently in coll. Zwick, Schlitz. Adult habitus. The teneral specimens are typical of genus Nemoura and possess no distinctive traits, apart from the genitalia. The front wing is 7.2 mm long. Male. Subgenital plate normal, with slender ventral vesicle and short pointed tip resting between the paraprocts. Paraproct transverse, short, apex bifid. The short medial lobe is narrow and separated from the broad external lobe by an angular notch (Fig. 32). Cercus in lateral view (Fig. 34) basally straight, apically regularly downcurved, sclerotization ending in two widely separate short points. Medially from them appears the large bulbous setose apex which is membraneous. In ventral view (Fig. 32) the cercus gently tapers from the base to a neck-like section supporting the large apex resembling a bird head. The caudal end of the dorsal sclerite and the outer point together appear as a narrow caudal edge. In dorsal view (Fig. 33) appears an indistinct mediocaudal point, in addition to the two lateral points. In caudal view (Fig. 35) the sclerite forms a flat cap over the cercus tip and both the mediocaudal point and the external caudal point are seen. The epiproct is oval, a little restricted anteriorly from midlength (Fig. 36). The narrow ventral sclerite bears about 10 slender spines. The rod-like apical sclerite extends forward but does not reach beyond the general contour of the epiproct. The sclerite's apex is rough, basally from it the tips of two outwardly directed straight spines are exposed. Apical sclerite and looped sclerite stand at a right angle to each other and are connected in a regular curve. The looped sclerite forms an oval ring. Female. Not known. Diagnosis. Paraproct and cercus resemble N. gemma, and details of the apical sclerite have also some resemblance. However, in N. gemma the epiproct contour is almost rhomboid. Its apical sclerites are obliquely connected to the looped sclerites and form a cone projecting far beyond the epiproct apex. Etymology. The name refers to the township of Lazo after which the beautiful stream along which the types were collected is named.

description: Ireland's coastline, a critical and dynamic resource, is facing challenges such as erosion, sedimentation, and human activities. Monitoring these changes is a complex task we approach using a combination of satellite imagery and deep learning methods. However, limited research exists in this area, particularly for Ireland. This paper presents the Landsat Irish Coastal Segmentation (LICS) dataset, which aims to facilitate the development of deep learning methods for coastal water body segmentation while addressing modelling challenges specific to Irish meteorology and coastal types. The dataset is used to evaluate various automated approaches for segmentation, with U-NET achieving the highest accuracy of 95.0% among deep learning methods. Nevertheless, the Normalised Difference Water Index (NDWI) benchmark outperformed U-NET with an average accuracy of 97.2%. The study suggests that deep learning approaches can be further improved with more accurate training data and by considering alternative measurements of erosion. The LICS dataset and code are freely available to support reproducible research and further advancements in coastal monitoring efforts.

description: The human ovary contains a fixed number of non-growing follicles (NGFs) established before birth that decline with increasing age culminating in the menopause at 50-51 years. The objective of this study is to model the age-related population of NGFs in the human ovary from conception to menopause. Data were taken from eight separate quantitative histological studies (n = 325) in which NGF populations at known ages from seven weeks post conception to 51 years (median 32 years) were calculated. The data set was fitted to 20 peak function models, with the results ranked by obtained r2 correlation coefficient. The highest ranked model was chosen. Our model matches the log-adjusted NGF population from conception to menopause to a five-parameter asymmetric double Gaussian cumulative (ADC) curve (r2 = 0.81). When restricted to ages up to 25 years, the ADC curve has r2 = 0.95. We estimate that for 95% of women by the age of 30 years only 12% of their maximum pre-birth NGF population is present and by the age of 40 years only 3% remains. Furthermore, we found that the rate of NGF recruitment towards maturation for most women increases from birth until approximately age 14 years then decreases towards the menopause. To our knowledge, this is the first model of ovarian reserve from conception to menopause. This model allows us to estimate the number of NGFs present in the ovary at any given age, suggests that 81% of the variance in NGF populations is due to age alone, and shows for the first time, to our knowledge, that the rate of NGF recruitment increases from birth to age 14 years then declines with age until menopause. An increased understanding of the dynamics of human ovarian reserve will provide a more scientfic basis for fertility counselling for both healthy women and those who have survived gonadotoxic cancer treatments.

Near-Infrared Spectroscopy of Trojan Asteroids: Evidence for Two Compositional Groups

description: The Trojan asteroids remain quite poorly understood, yet their physical properties provide unique perspective on chemical and dynamical processes that shaped the Solar System. The current study was undertaken to investigate surface compositions of these objects. We present 66 new near-infrared (NIR; 0.7 to 2.5 microns) spectra of 58 Trojans, including members of both the leading and trailing swarms. We also include in the analysis previously published NIR spectra of 13 Trojans (3 of which overlap with the new sample). This data set permits not only a direct search for compositional signatures, but also a search for patterns that may reveal clues to the origin of the Trojans. We do not report any confirmed absorption features in the new spectra. Analysis of the spectral slopes, however, reveals an interesting bimodality among the NIR data. The two spectral groups identified appear to be equally abundant in the leading and trailing swarms. The spectral groups are not a result of family membership; they occur in the background, non-family population. The average albedos of the two groups are the same within uncertainties (0.051\pm0.016 and 0.055\pm0.016). No correlations between spectral slope and any other physical or orbital parameter are detected, with the exception of a possible weak correlation with inclination among the less-red spectral group. Synthesizing these results with previously published properties, we conclude that the two spectral groups represent objects with different intrinsic compositions. We further suggest that while the less-red group originated near Jupiter or in the main asteroid belt, the redder spectral group originated farther out in the Solar System. If correct, the Trojan swarms offer the most readily accessible large reservoir of Kuiper Belt material as well as a unique reservoir for the study of material from the middle part of the solar nebula.

description: Inspired by recent progress in fabricating precisely zigzag-edged graphene nanoribbons and the observation of edge magnetism, we find that spin polarized edge modes with well-defined valley index can exist in a bulk energy gap opened by a staggered sublattice potential such as that provided by a hexagonal Boron-Nitride substrate. Our result is obtained by both tight-binding model and first principles calculations. These edge modes are helical with respect to the valley degree of freedom, and are robust against scattering, as long as the disorder potential is smooth over atomic scale, resulting from the protection of the large momentum separation of the valleys.

Frame allocation for smart phone based games using clouds
Creators: name: Sandhu, Vikramjit Singh
Publisher: name: University of British Columbia
Year: 2014

description: This thesis considers exploiting the channel dynamics and the cloud state information for optimal frame allocation of video frames between a cloud gaming server and a mobile user. Such scheduling offloads the computational workload of running graphically intensive applications from the smart-phone onto the cloud, thereby extending the battery life of the smart-phone. The objective is to achieve a trade-off between the number of high resolution and low resolution frames sent, subject to delivering a minimum total number of frames within a pre-defined deadline. To tackle this objective, the trade-off has been formulated as a Markov Decision Process. It is proved that the optimal frame allocation policy for transmitting video frames from the cloud is monotone in both the number of frames transmitted as well as the time taken to transmit those frames. Finally, a simulation based stochastic optimization algorithm is presented which exploits the monotone structure of the optimal policy - the algorithm estimates the optimal policy without knowledge of the transition probabilities.

description: Measured exponents associated with Stretched Exponential Relaxation (SER) are widely scattered in microscopically inhomogeneous glasses, but accurately bifurcate into two "magic" values, 3/5 and 3/7, in a wide variety of microscopically homogeneous glasses. These bifurcated values are derived here from a statistical product model that involves diffusion of excitations to native traps in the presence of short-range forces only, or combined short- and long- range forces, respectively. Bifurcated SER can be used to monitor sample homogeneity. It explains a wide range of experimental data, and even includes multiple aspects of the citation distributions of 20th century science, involving 25 million papers and 600 million citations, and why these changed radically in 1960. It also shows that the distribution of country population sizes has compacted glassy character, and is strongly influenced by migration.

description: A study of the eta'->eta pi pi Dalitz plot distribution is presented in this talk. The size of the branching ratio is properly understood within U(3) Chiral Perturbation Theory and Resonance Chiral Theory, in the framework of the 1/Nc expansion. Nonetheless, unitarity effects of pion loops must be incorporated in order to achieve an appropriate description of the Dalitz slope parameters. After taking the final state interactions into account, our predictions become now in agreement with the available experimental measurements, although some clear differences show up with respect to previous theoretical estimates.

description: In this paper, a method for efficient scheduling to obtain optimum job throughput in a distributed campus grid environment is presented; Traditional job schedulers determine job scheduling using user and job resource attributes. User attributes are related to current usage, historical usage, user priority and project access. Job resource attributes mainly comprise of soft requirements (compilers, libraries) and hard requirements like memory, storage and interconnect. A job scheduler dispatches jobs to a resource if a job's hard and soft requirements are met by a resource. In current scenario during execution of a job, if a resource becomes unavailable, schedulers are presented with limited options, namely re-queuing job or migrating job to a different resource. Both options are expensive in terms of data and compute time. These situations can be avoided, if the often ignored factor, availability time of a resource in a grid environment is considered. We propose resource rank approach, in which jobs are dispatched to a resource which has the highest rank among all resources that match the job's requirement. The results show that our approach can increase throughput of many serial / monolithic jobs.

description: In gamma-ray-bursts (GRB), ultra-relativistic blast waves are ejected into the circumburst medium. We analyse in unprecedented detail the deceleration of a self-similar Blandford-McKee blast wave from a Lorentz factor 25 to the nonrelativistic Sedov phase. Our goal is to determine the stability properties of its frontal shock. We carried out a grid-adaptive relativistic 2D hydro-simulation at extreme resolving power, following the GRB jet during the entire afterglow phase. We investigate the effect of the finite initial jet opening angle on the deceleration of the blast wave, and identify the growth of various instabilities throughout the coasting shock front. We find that during the relativistic phase, the blast wave is subject to pressure-ram pressure instabilities that ripple and fragment the frontal shock. These instabilities manifest themselves in the ultra-relativistic phase alone, remain in full agreement with causality arguments, and decay slowly to finally disappear in the near-Newtonian phase as the shell Lorentz factor drops below 3. From then on, the compression rate decreases to levels predicted to be stable by a linear analysis of the Sedov phase. Our simulations confirm previous findings that the shell also spreads laterally because a rarefaction wave slowly propagates to the jet axis, inducing a clear shell deformation from its initial spherical shape. The blast front becomes meridionally stratified, with decreasing speed from axis to jet edge.

description: Advances in embedded devices and wireless sensor networks have resulted in new and inexpensive health care solutions. This paper describes the implementation and the evaluation of a wireless body sensor system that monitors human physiological data at home. Specifically, a waist-mounted triaxial accelerometer unit is used to record human movements. Sampled data are transmitted using an IEEE 802.15.4 wireless transceiver to a data logger unit. The wearable sensor unit is light, small, and consumes low energy, which allows for inexpensive and unobtrusive monitoring during normal daily activities at home. The acceleration measurement tests show that it is possible to classify different human motion through the acceleration reading. The 802.15.4 wireless signal quality is also tested in typical home scenarios. Measurement results show that even with interference from nearby IEEE 802.11 signals and microwave ovens, the data delivery performance is satisfactory and can be improved by selecting an appropriate channel. Moreover, we found that the wireless signal can be attenuated by housing materials, home appliances, and even plants. Therefore, the deployment of wireless body sensor systems at home needs to take all these factors into consideration.

description: We present new Giant Metrewave Radio Telescope observations at 235 MHz and 610 MHz of 18 X-ray bright galaxy groups. These observations are part of an extended project, presented here and in future papers, which combines low-frequency radio and X-ray data to investigate the interaction between central active galactic nuclei (AGN) and the intra-group medium (IGM). The radio images show a very diverse population of group-central radio sources, varying widely in size, power, morphology and spectral index. Comparison of the radio images with Chandra and XMM-Newton X-ray images shows that groups with significant substructure in the X-ray band and marginal radio emission at >= 1 GHz host low-frequency radio structures that correlate with substructures in IGM. Radio-filled X-ray cavities, the most evident form of AGN/IGM interaction in our sample, are found in half of the systems, and are typically associated with small, low- or mid-power double radio sources. Two systems, NGC5044 and NGC4636, possess multiple cavities, which are isotropically distributed around the group center, possibly due to group weather. In other systems the radio/X-ray correlations are less evident. However, the AGN/IGM interaction can manifest itself through the effects of the high-pressure medium on the morphology, spectral properties and evolution of the radio-emitting plasma. In particular, the IGM can confine fading radio lobes in old/dying radio galaxies and prevent them from dissipating quickly. Evidence for radio emission produced by former outbursts that coexist with current activity is found in six groups of the sample.

description: The present study aims to assess the cytotoxic effect of the aqueous and protease inhibitors extracts of Sterculia striata on breast cancer cell lines. The in vitro results showed significant reductions in the highest concentrations from the S. striata seed extract for all cell lines. The aqueous extract reduced the viability by up to 35% in the MCF-7, 25% in the 4T1, and 35% in the MDA-MB-231 cell lines. Regarding the protease inhibitor extract, a 50% reduction in cell viability was observed in the MDA-MB-231 at concentration of 333 µg/mL. The aqueous and the protease inhibitor extracts showed mild reduction in the viability of macrophage cell lines. Chemical characterisation analysis revealed several polyphenols such as flavonoids, tannins, phenolic acids, and other secondary metabolites including terpenes, steroids, fatty acids, and organic acids, which may be related to the promising bioactivity observed. The S. striata showed antitumor activity, emphasising its pharmacological potential.

description: Spin relaxation in quantum Hall ferromagnet regimes is studied. As the initial non-equilibrium state, a coherent deviation of the spin system from the ${\vec B}$ direction is considered and the breakdown of this Goldstone-mode state due to hyperfine coupling to nuclei is analyzed. The relaxation occurring non-exponentially with time is studied in terms of annihilation processes in the "Goldstone condensate" formed by "zero spin excitons". The relaxation rate is calculated analytically even if the initial deviation is not small. This relaxation channel competes with the relaxation mechanisms due to spin-orbit coupling, and at strong magnetic fields it becomes dominating.

description: Today every circuit has to face the power consumption issue for both portable device aiming at large battery life and high end circuits avoiding cooling packages and reliability issues that are too complex. It is generally accepted that during logic synthesis power tracks well with area. This means that a larger design will generally consume more power. The multiplier is an important kernel of digital signal processors. Because of the circuit complexity, the power consumption and area are the two important design considerations of the multiplier. In this paper a low power low area architecture for the shift and add multiplier is proposed. For getting the low power low area architecture, the modifications made to the conventional architecture consist of the reduction in switching activities of the major blocks of the multiplier, which includes the reduction in switching activity of the adder and counter. This architecture avoids the shifting of the multiplier register. The simulation result for 8 bit multipliers shows that the proposed low power architecture lowers the total power consumption by 35.25% and area by 52.72 % when compared to the conventional architecture. Also the reduction in power consumption increases with the increase in bit width.

Interference in wireless mobile networks

description: Given a set of positions for wireless nodes, the interference minimization problem is to assign a transmission radius (i.e., a power level) to each node such that the resulting communication graph is connected, while minimizing the maximum (respectively, average) interference. We consider the model introduced by von Rickenbach et al. (2005), in which each wireless node is represented by a point in Euclidean space on which is centered a transmis- sion range represented by a ball, and edges in the corresponding graph are symmetric. The problem is NP-complete in two or more dimensions (Buchin 2008) and no polynomial-time approximation algorithm is known. We show how to solve the problem efficiently in settings typical for wireless ad hoc networks. We show that if node positions are represented by a set P of n points selected uniformly and independently at random over a d-dimensional region, then the topology given by the closure of the Euclidean minimum spanning tree of P has O(log n) maximum interference, O(1) average inter- ference with high probability and O(1) expected average interference. This work is the first to examine average interference in random settings. We extend the first bound to a general class of communication graphs over a broad set of probability distributions. We present a local algorithm that constructs a graph from this class; this is the first local algorithm to provide an upper bound on expected maximum interference. To verify our results, we perform an empirical evaluation using synthetic as well as real world node placements.

description: The search for new interactions of neutrinos beyond those of the Standard Model may help to elucidate the mechanism responsible for neutrino masses. Here we combine existing accelerator neutrino data with restrictions coming from a recent atmospheric neutrino data analysis in order to lift parameter degeneracies and improve limits on new interactions of muon neutrinos with quarks. In particular we re-consider the results of the NuTeV experiment in view of a new evaluation of its systematic uncertainties. We find that, although constraints for muon neutrinos are better than those applicable to tau or electron neutrinos, they lie at the few $\times 10^{-2}$ level, not as strong as previously believed. We briefly discuss prospects for further improvement.

description: The abundance of chlorine is determined from X-ray spectra obtained with the RESIK instrument on {\em CORONAS-F} during solar flares between 2002 and 2003. Using weak lines of He-like Cl, \ion{Cl}{16}, between 4.44 and 4.50 Å, and with temperatures and emission measures from {\em GOES} on an isothermal assumption, we obtained $A({\rm Cl}) = 5.75 \pm 0.26$ on a scale $A({\rm H}) = 12$. The uncertainty reflects an approximately factor 2 scatter in measured line fluxes. Nevertheless our value represents what is probably the best solar determination yet obtained. It is higher by factors of 1.8 and 2.7 than Cl abundance estimates from an infrared sunspot spectrum and nearby \ion{H}{2} regions. The constancy of the RESIK abundance values over a large range of flares ({\em GOES} class from below C1 to X1) argues for any fractionation that may be present in the low solar atmosphere to be independent of the degree of solar activity.

description: From the explicit solutions of Maxwell's equations under the coordinate transformation, the conditions for non-reflecting boundaries for the two-dimensionally propagating light waves, in a finite-embedded coordinate transformation metamaterial slab are derived in cases of extended two-dimensional. By exploring several examples, including some reported in the literatures and some novel developed in this study, we show that our approach can be used to efficiently determine the condition in which a finite-embedded coordinate transformed metamaterial slab is non-reflecting.

Vibration, static standing, dynamic standing, and spasticity in individuals with spinal cord injury
Creators: name: Sadeghi, Mahsa
Publisher: name: University of British Columbia
Year: 2014

description: Spasticity is a common consequence of upper motor neuron lesions such as spinal cord injury (SCI). Spasticity is experienced by 65-78% of individuals with SCI. Spasticity management is one of the most important challenges that clinicians and researchers encounter. Physical therapy techniques are the essential component of spasticity management that are used during and after other spasticity management tools. Vibration and standing training are two physiotherapy techniques that might be beneficial to manage spasticity in individuals with SCI. This thesis is divided into two major parts to study how these two physiotherapy techniques are useful to manage spasticity in individuals with SCI. The first study was a systemic review exploring how effective whole body and focal vibration are for spasticity management in individuals with SCI. The second study was a cross-over study that evaluated the difference between the effects of static and dynamic (using the Segway) standing training on spasticity immediately and one hour after the interventions in individuals with SCI. Spasticity was measured by three different outcome measures including self-assessment (visual analog scale), clinical (Modified Ashworth Scale), and electrophysiologic (electromyography) measures. There was evidence to support the decreasing effects of either whole body or focal vibration on spasticity in individuals with SCI. There was no statistically significant difference between the dynamic and static standing interventions for spasticity reduction. We concluded that vibration (focal and whole body) has promising effects for spasticity reduction in individuals with SCI. We also concluded that dynamic standing training has no greater effect on spasticity reduction compared to the static standing training.

description: The magnetocaloric effect (MCE) of A-site ordered PrBaMn2O6 manganite has been studied by direct methods and by the specific heat measurements. Direct measurements of the MCE in low magnetic fields were performed using recently proposed modulation technique and by classic direct method in high fields. Direct and inverse MCE are observed at Curie and Neel points correspondingly. A value of the inverse MCE in the heating run is less than in the cooling regime. This effect can be attributing to competition between ferromagnetic and antiferromagnetic interactions. Indirectly estimated and direct MCE values considerably differ in around first order AF transition.

description: About 4" south of the young A0-type star HR 7329, a faint companion candidate was found by Lowrance et al. (2000). Its spectral type of M7-8 is consistent with a young brown dwarf companion. Here, we report ten new astrometric imaging observations of the pair HR 7329 A and B, obtained with the Hubble Space Telescope and the Very Large Telescope, aimed at showing common proper motion with high significance and possible orbital motion of B around A. With 11 yrs of epoch difference between the first and our last image, we can reject by more than 21 sigma that B would be a non-moving background object unrelated to A. We detect no change in position angle and small or no change in separation (2.91 +/- 2.41 mas/yr), so that the orbit of HR 7329 B around A is inclined and/or eccentric and/or the orbital motion is currently only in radial direction. If HR 7329 B is responsible for the outer radius of the debris disk around HR 7329 A being 24 AU, and if HR 7329 B currently is at its apastron at 200 AU (4.2" at 47.7 pc), we determine its pericenter distance to be 71 AU, its semi-major axis to be 136 AU, and its eccentricity to be e=0.47. From the magnitude differences between HR 7329 A and B and the 2MASS magnitudes for the HR 7329 A+B system, we can estimate the magnitudes of HR 7329 B (J=12.06+/-0.19, H=11.75+/-0.10, Ks=11.6+/-0.1, L=11.1+/-0.2 mag) and then, with a few otherwise known parameters, its luminosity and mass (20-50 Jupiter masses). In the deepest images available, we did not detect any additional companion candidates up to <=9", but determine upper limits in the planetary mass regime.
