Effect of transverse vibration upon the rate of sublimation from horizontal cylinders
Creators: name: Sugano, Yuzuru
Publisher: name: University of British Columbia
Year: 2011

description: The effect of vibration upon the rate of sublimation from horizontal circular cylinders has been studied previously in several investigations. However, no satisfactory overall correlation has been obtained up to the present time. In the present investigation, data have been obtained for mass transfer from naphthalene to air and phenol to air for horizontal cylinders vibrated vertically over a wide range of Reynolds number. It is shown that these data and the data of all previous investigations, including liquid systems, lie on or near a single smooth curve provided that an appropriate system of coordinates is selected. Further, for high Reynolds number and high Schmidt number, the data approach the theoretical equation of Jameson derived using boundary-layer theory. The author has found that the mass transfer coefficient for sublimation can be increased by a factor of 30 over that which prevails for the stationary (non-vibrating) case. For mass transfer to gaseous media only, the following correlation is proposed, having an average deviation of ±17 % : Sh = 0.261 Sc¹/³Revº•⁷¹⁷( H/d )º•²³³ This equation is believed to be valid over the following range of the variables: Diameter: 0.07 - 1.1 cm Frequency: 100 - 7000 RPM Amplitude (double): 0.05 - 4.0 cm Vibrational Reynolds number: 9 - 2000 Ratio of amplitude to diameter: 0.2 - 5.7

description: The workshop ‘Group Theory, Measure, and Asymptotic Invariants’ organized by Miklos Abert (Budapest), Damien Gaboriau (Lyon) and Andreas Thom (Leipzig) was held 18 - 24 August 2013. The event was a continuation of the previous Oberwolfach workshop ‘Actions and Invariants of Residually Finite Groups: Asymptotic Methods’ organized by Miklos Abert (Budapest), Damien Gaboriau (Lyon) and Fritz Grunewald (Dusseldorf) that was held September 5 - September 11, 2010. Fritz Grunewald passed away in March 2010 and Andreas Thom joined the organizing team. The workshop aimed to study finitely generated groups and group actions using ergodic and measure theoretic methods, incorporating asymptotic invariants, such as ℓ2-invariants, the rank gradient, cost, torsion growth, entropy-type invariants and invariants coming from random walks and percolation theory. The participant body came from a wide range of areas: finite and infinite group theory, geometry, ergodic theory, graph theory, topology, probability theory, representation theory, von Neumann algebras and $\mathcal l^2$-theory. The participants typically did not speak each other’s mathematical dialect fluently. To address this situation, the organizers asked the speakers to put a special emphasis on the first, introductory part of their talks. This aspect worked very well. As a general rule, the organizers asked speakers to talk about specific subjects, not just any nice piece of their research. In some cases, this meant sacrificing hearing about some new results from excellent mathematicians that were further away from the workshop’s main directions.

description: We prove that a compact Riemann surface can be realized as a pseudo-holomorphic curve of $(\mathbb{R}^4,J)$, for some almost complex structure $J$ if and only if it is an elliptic curve. Furthermore we show that any (almost) complex $2n$-torus can be holomorphically embedded in $(\mathbb{R}^{4n},J)$ for a suitable almost complex structure $J$. This allows us to embed any compact Riemann surface in some almost complex Euclidean space and to show many explicit examples of almost complex structure in $\mathbb{R}^{2n}$ which can not be tamed by any symplectic form.

High resolution MMR of organotin compounds and ESR study of X-ray irradiated organic single crystals
Creators: name: Cyr, Natsuko
Publisher: name: University of British Columbia
Year: 2011

description: In part I of this thesis, orgimotin compounds were investigated, using high resolution proton and tin 119 nuclear magnetic resonance technique. The tin 119 chemical shift of about forty organotin compounds were measured by absorption mode for the first time. The tin chemical shift and tin 119-proton coupling constant in some methyltinhalides wore found, to be solvent and concentration dependent in electron donor solvents. This dependence was attributed to the formation of higher than four coordinated complexes with solvent molecules. Equilibrium constants of the complex formation, the tin chemical shifts, and the tin-proton coupling constants of the complexes, wore obtained in a few solvents. The second-order paramagnetic chemical shifts of methyltinhaiides, methyltin cations, and five coordinated compounds were calculated and compared with the observed tin chemical shifts. Good qualitative agreements between calculated values and observed values confirmed that the second-order paramagnetic term in tin chemical shifts is dominant in the chemical shift changes in those compounds. In part II, X-ray irradiated single crystals of malonamide and cyanoacetamide were studied by electron spin resonance technique. In both cases at least two types of radicals were found. One was the usual π -electron type radical the proton coupling tensor of which had been studied, quite extensively in the past. In this study, besides the proton coupling and in the case of cyanoaecetamide, the coupling tensor for the cyano-nitrogen was also measured and discussed. The second radical found both in X-ray irradiated malonamide and cyanoacetamide was a Ϭ-electron type radical which was produced by the loss of one of the amide protons (-COṄH). The proton hyperfine coupling constant was found to be almost isotropic and very large, more than 80 gauss in both compounds. The nitrogen coupling tensor for the amide- nitrogen was found to be axially symmetric with the unique principal value equal to 36.6 gauss in the one (malonamide) and 25.4 gauss in the other (cyanoacetamide). The principal value in perpendicular direction was found to be very small but could not be determined conclusively. A semi-empirical molecular orbital calculation was performed on the fragment of Ϭ-electron radical together with perturbation through configuration interaction; the large isotropic proton coupling constants were explained theoretically.

description: Security issues are playing dominant role in today's high speed communication systems. A fast and compact FPGA based implementation of the Data Encryption Standard (DES) and Triple DES algorithm is presented in this paper that is widely used in cryptography for securing the Internet traffic in modern day communication systems. The design of the digital cryptographic circuit was implemented in a Vertex 5 series (XCVLX5110T) target device with the use of VHDL as the hardware description language. In order to confirm the expected behavior of these algorithms, the proposed design was extensively simulated, synthesized for different FPGA devices both in Spartan and Virtex series from Xilinx viz. Spartan 3, Spartan 3AN, Virtex 5, Virtex E device families. The novelty and contribution of this work is in three folds: (i) Extensive simulation and synthesis of the proposed design targeted for various FPGA devices, (ii) Complete hardware implementation of encryption and decryption algorithms onto Virtex 5 series device (XCVLX5110T) based FPGA boards and, (iii) Generation of ICON and VIO core for the design and on chip verification and analyzing using Chipscope Pro. The experimental as well as implementation results compared to the implementations reported so far are quite encouraging.

description: Amid the coronavirus disease 2019 (COVID-19) pan‐demic caused by the SARS-CoV2 virus, and among themany difficult questions we are facing day-by-day, arather unusual question has challenged neurologists:Where is everybody with acute ischemic stroke?Recently, on the popular physician site Medscape, thequestion was raised whether patients with acute strokewere not seeking emergency care, based on reports fromneurologists who reported to be experiencing an unusu‐ally low number of patients with acute ischemic stroke(AIS) [1]. In this commentary, we explore three poten‐tial explanations that might help us to take advantage ofthe situation and gain some insight about both entities.The first explanation is that patients with acute strokeare staying at home due to fear of COVID-19 contagion.This hypothesis suggests that patients with minor AIS ortransient ischemic attacks (TIAs) do not seek attentionbecause of the low severity of symptoms. Althoughplausible, it is not only minor strokes or TIAs that havedecreased. In our hospital, a regional reference centerthat serves five states on northeastern Mexico, we havewitnessed a decreasing trend in stroke cases admitted tothe neurology ward after March 1, which also has beenreported by the weekly epidemiological bulletin fromthe health ministry. A situation similar to that reportedby neurologists on Medscape, and by cardiologists inThe New York Times, who reported less patients pre‐senting with coronary events [2], with unconfirmedreports from New York City’s emergency respondersthat at-home deaths from cardiac arrests had skyrocketed

description: We study a sample of 16 microlensed Galactic bulge main sequence turnoff region stars for which high dispersion spectra have been obtained with detailed abundance analyses. We demonstrate that there is a very strong and highly statistically significant correlation between the maximum magnification of the microlensed bulge star and the value of the [Fe/H] deduced from the high resolution spectrum of each object. Physics demands that this correlation, assuming it to be real, be the result of some sample bias. We suggest several possible explanations, but are forced to reject them all,and are left puzzled. To obtain a reliable metallicity distribution in the Galactic bulge based on microlensed dwarf stars it will be necessary to resolve this issue through the course of additional observations.

Two important classes of communication circuit, delta modulator and compander have been designed using that procedure. In the first implementation coded pulse modulation system is demonstrated which employ sampling, quantizing and coding to convert analog waveforms to digital signals while the second gives data compression and expansion in digital communication system. The proposed compander circuit is realized with operational transconductance amplifier and diode. Required power supply to operate the circuit is 3.5V. Performance of the circuits realized with OTAs has been demonstrated through SPICE simulation.

description: Multinational fast-moving consumer goods corporations such as Procter & Gamble, Unilever, and Coca-Cola are the highest producers of plastic pollution in the world, and yet take little-to-no responsibility for the waste after the end of their product’s useful life. Single-use plastics, such as those used for bottles, wrappers, straws, bags, and more, end up wasted in landfills, waterways, and ecosystems all around the world. The challenges associated with managing large and diverse streams of waste are complex, and the repercussions can be far-reaching, but the circular economy has proved to be promising in eliminating some of this stress. The circular economy is a proposed economic system aimed at eliminating waste and the continual use of resources and has tremendous organizing potential. In this thesis, I will discuss the catastrophic impact of the United States’ single-use plastics addiction and evaluate the reusable methods of packaging among various types of household products in an attempt to drastically cut single-use plastics output. I will specifically focus on the opportunities and challenges of “refillables,” or items where consumers can easily obtain regular household items in bulk. I will evaluate similar circular economy projects that already exist in the market using reuse models, such as the Unboxed Market in Canada that has completely eliminated single-use plastics, and create a cost-savings model to demonstrate how a company can implement circular economy into their overall strategy.

description: The hyperspherical harmonic basis is used to describe bound states in an $A$--body system. The approach presented here is based on the representation of the potential energy in terms of hyperspherical harmonic functions. Using this representation, the matrix elements between the basis elements are simple, and the potential energy is presented in a compact form, well suited for numerical implementation. The basis is neither symmetrized nor antisymmetrized, as required in the case of identical particles; however, after the diagonalization of the Hamiltonian matrix, the eigenvectors reflect the symmetries present in it, and the identification of the physical states is possible, as it will be shown in specific cases. We have in mind applications to atomic, molecular, and nuclear few-body systems in which symmetry breaking terms are present in the Hamiltonian; their inclusion is straightforward in the present method. As an example we solve the case of three and four particles interacting through a short-range central interaction and Coulomb potential.

The photovoltaic Berry curvature (a nonequilibrium extension of the standard Berry curvature) is the key quantity to understand this effect, which appears in the Kubo formula extended to Hall transport in the presence of strong AC field backgrounds. Here we elaborate the properties of the photovoltaic curvature such as the frequency and field strength dependence in the honeycomb lattice.

description: Consider the degeneracies of BPS bound states of one D6 brane wrapping Calabi-Yau X with D0 branes and D2 branes. When we include D4-branes wrapping Lagrangian cycle L in addition, D2-branes can end on them. These give rise to new bound states in the d=2, N=(2,2) theory of the D4 branes. We call these "open" BPS states, in contrast to closed BPS states that arise from D-branes without boundaries. Lifting this to M-theory, we show that the generating function is captured by free Fock space spanned by M2-brane particles ending on M5 branes wrapping L. This implies that the open BPS bound states are counted by the square of the open topological string partition function on X, reduced to the corresponding chamber. Our results give new predictions for open BPS invariants and their wall crossing phenomena when we change the open and closed string moduli. We relate our results to the work of Cecotti and Vafa on wall crossing in the two dimensional N=(2,2) theories. The findings from the crystal melting model for the open BPS invariants proposed recently fit well with the M-theory predictions.

An anti-correlation between X-ray luminosity and H-alpha equivalent width in X-ray binaries

description: We report an anticorrelation between continuum luminosity and the equivalent width (EW) of the H-alpha emission line in X-ray binary systems. The effect is evident both in a universal monotonic increase in H-alpha EW with time following outbursts, as systems fade, and in a comparison between measured EWs and contemporaneous X-ray measurements. The effect is most clear for black hole binaries in the low/hard X-ray state, which is prevalent at X-ray luminosities below ~1% Eddington. We do not find strong evidence for significant changes in line profiles across accretion state changes, but this is hampered by a lack of good data at such times. The observed anti-correlation, highly significant for black hole binaries, is only marginally so for neutron star systems, for which there are far less data. Comparison with previously established correlations between optical and X-ray luminosity suggest that the line luminosity is falling as the X-ray and optical luminosities drop, but not as fast (approximately as L_{H-alpha} \propto L_X^{~0.4} \propto L_{opt}^{~0.7}). We briefly discuss possible origins for such an effect, including the optical depth, form of the irradiating spectrum and geometry of the accetion flow. Further refinement of the relation in the future may allow measurements of H-alpha EW to be used to estimate the luminosity of, and hence the distance to, X-ray binary systems. Beyond this, further progress will require a better sample of spectro-photometric data.

Formation, reactions and spectra of some group V free-radicals

Publisher: name: University of British Columbia
Year: 2011

description: Metastable, electronically excited atoms (²Dº , ²Pº ) of phosphorus, arsenic and antimony have been observed following the isothermal flash photolysis of Group VA hydrides and trihalides. Several mechanisms for the production of these atoms are discussed. The decay of the excited atoms was observed to be rapid due to reactions with the transients produced in the flash photolysis of the parent compounds. Flash photolysis of the Group VA hydrides and trichlorides has yielded new electronic absorption spectra of the AsH and AsH₂, SbH and SbH₂, PC1, AsC1, and SbC1 free-radicals. Vibrational analysis on some of these spectra have been carried out. In the isothermal flash photolysis of cyanogen with Group VA hydrides, it is proposed that the following reactions of the cyanogen radical occur rapidly: CN + AH₃ → AH₂ + HCN (1) CN + AH₂ → AH + HCN (2) CN + AH → ACN + H (A=N,P,As) (3) → HCN + A* (A=P,As, Sb) (4) (formula omitted) HACN (A=N,P) (5) where A, unless specified, is N, P, As or Sb and * denotes electronic excitation. Three of the new electronic absorption spectra observed are tentatively attributed to the PCN, HPCN and AsCN free-radicals produced in reactions (3) and (5). The assignment of the other spectra is discussed. Reactions of CN with NF, PC1 and AsC1, corresponding to (3), have also been shown to occur rapidly. The reactions of the cyanogen radical in the flash photolysis of cyanogen with nitrous oxide, oxygen, water, and methyl isocyanate have also been studied and discussed.

description: Structure in the Universe is widely believed to have originated from quantum fluctuations during an early epoch of accelerated expansion. Yet, the patterns we observe today do not distinguish between quantum or classical primordial fluctuations; current cosmological data are consistent with either possibility. We argue here that a detection of primordial non-Gaussianity can resolve the present situation, and provide a litmus test for the quantum origin of cosmic structure. Unlike in quantum mechanics, vacuum fluctuations cannot arise in classical theories and therefore long-range classical correlations must result from (real) particles in the initial state. Similarly to flat-space scattering processes, we show how basic principles require these particles to manifest themselves as poles in the n-point functions, in the so-called folded configurations. Following this observation, and assuming fluctuations are (i) correlated over large scales and (ii) generated by local evolution during an inflationary phase, we demonstrate that the absence of a pole in the folded limit of non-Gaussian correlators uniquely identifies the quantum vacuum as the initial state. In the same spirit as Bell’s inequalities, we discuss how this can be circumvented if locality is abandoned.

title: Work and being: a hermeneutical study
Creators: name: Mei, Todd S.
Publisher: name: University of Kent

description: The problematic dilemma motivating my thesis is how the contemporary understanding of work fails to regard human production as anything more than a necessary activity. This manifests in various ways, most predominantly in terms of utilitarian conceptions about the purpose of work and how it uses nature as the raw material for human ends. After an analysis that identifies the philosophical foundations of the contemporary attitude in Enlightenment suppositions and Marx's philosophy of work, I develop an alternative conception of work that discloses its ontological, as opposed to instrumental, nature. Following the hermeneutics of Martin Heidegger and Paul Ricoeur, I show how this ontological constitution suggests that work is more appropriately defined as a thanking activity—i.e., giving thanks to being itself. This is because thanking is fundamentally related to the reflective, or thinking, capacity of human being that inevitably seeks to understand life in relation to an interpretation of the meaning of being. To interpret is, in this respect, a manner of giving thanks to being. Hence, I argue that work's thanking aspect is most evident in terms of how it metaphorically discloses an interpretation of the meaning of being through its artefacts and structures that are integrated into the whole of human doing and thinking. This extends to even the most literal aspects of necessity concerned with biological and economic sustenance. With respect to the historical conception of the relation between work and thinking, that is generally understood as the division between vita activa and vita contemplativa, my thesis shows how these two modes of being are united within a broader, ontological description of human activity since these modes require and mutually develop one another. A prime instance of this concerns the area of human vocation which I focus on in my concluding chapter. I contend that vocation is an actualisation of interpretive horizons of meaning. It is, in short, the praxical and poetical realisation of theoretical interpretation.

description: Self-diffusion of a sphere in a network of rods is analyzed theoretically. Hydrodynamic interactions are taken into account according to the model of Dhont et al., under the assumption that $\ka << 1$ and $\bar{a}/L<<1$, where $1/κ$ is the network hydrodynamic screening length, $\bar{a}=a+D/2$, and $a$ is the sphere radius, while $D$ and $L$ are the diameter and length of a rod, respectively. Simple expressions for the diffusion coefficients are derived and shown to be independent of $L$.

Inflation on the Brane with Vanishing Gravity
Creators: name: Gallicchio, Jason

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Many existing models of brane inflation suffer from a steep irreducible gravitational potential between the branes that causes inflation to end too early. Inspired by the fact that point masses in 2+1 D exert no gravitational force, we propose a novel unwarped and non-supersymmetric setup for inflation, consisting of 3-branes in two extra dimensions compactified on a sphere. The size of the sphere is stabilized by a combination of a bulk cosmological constant and a magnetic flux. Computing the 4D effective potential between probe branes in this background, we find a non-zero contribution only from exchange of level-1 KK modes of the graviton and radion. Identifying antipodal points on the 2-sphere projects out these modes, eliminating entirely the troublesome gravitational contribution to the inflationary potential.

Neutron transition strengths of $2^+_1$ states in the neutron rich Oxygen isotopes determined from inelastic proton scattering

description: A coupled-channel analysis of the $^{18,20,22}$O$(p,p')$ data has been performed to determine the neutron transition strengths of 2$^+_1$ states in Oxygen targets, using the microscopic optical potential and inelastic form factor calculated in the folding model. A complex density- and \emph{isospin} dependent version of the CDM3Y6 interaction was constructed, based on the Brueckner-Hatree-Fock calculation of nuclear matter, for the folding model input. Given an accurate isovector density dependence of the CDM3Y6 interaction, the isoscalar ($δ_0$) and isovector ($δ_1$) deformation lengths of 2$^+_1$ states in $^{18,20,22}$O have been extracted from the folding model analysis of the $(p,p')$ data. A specific $N$-dependence of $δ_0$ and $δ_1$ has been established which can be linked to the neutron shell closure occurring at $N$ approaching 16. The strongest isovector deformation was found for 2$^+_1$ state in $^{20}$O, with $δ_1$ about 2.5 times larger than $δ_0$, which indicates a strong core polarization by the valence neutrons in $^{20}$O. The ratios of the neutron/proton transition matrix elements ($M_n/M_p$) determined for 2$^+_1$ states in $^{18,20}$O have been compared to those deduced from the mirror symmetry, using the measured $B(E2)$ values of 2$^+_1$ states in the proton rich $^{18}$Ne and $^{20}$Mg nuclei, to discuss the isospin impurity in the $2^+_1$ excitation of the $A=18,T=1$ and $A=20,T=2$ isobars.

description: SAX J2103.5+4545 is the Be/X-ray binary with the shortest orbital period. It shows extended bright and faint X-ray states that last for a few hundred days. The main objective of this work is to investigate the relationship between the X-ray and optical variability and to characterise the spectral and timing properties of the bright and faint states. We have found a correlation between the spectral and temporal parameters that fit the energy and power spectra. Softer energy spectra correspond to softer power spectra. That is to say, when the energy spectrum is soft the power at high frequencies is suppressed. We also present the results of our monitoring of the Halpha line of the optical counterpart since its discovery in 2003. There is a correlation between the strength and shape of the Halpha line, originated in the circumstellar envelope of the massive companion and the X-ray emission from the vicinity of the neutron star. Halpha emission, indicative of an equatorial disc around the B-type star, is detected whenever the source is bright in X-rays. When the disc is absent, the X-ray emission decreases significantly. The long-term variability of SAX J2103.5+4545 is characterised by fast episodes of disc loss and subsequent reformation. The time scales for the loss and reformation of the disc (about 2 years) are the fastest among Be/X-ray binaries.

Subjects: Head and Neck Cancer, Smoking, Larynx Carcinoma, TNM classification, Squamous Cell Carcinoma.

description: Abstract

Aim: The purpose of this study was to find out the relationship of smoking with demographic and clinical features of Head and Neck Cancer (HNC) patients visiting Nishtar Hospital Multan, Pakistan. Even though there has been a lot of studies conducted regarding the many aspects of HNC around the world, but Southern Punjab, Pakistan, no online information is available to our knowledge. Materials and methods: Demographic and clinical information from HNC patients was obtained and analyzed with respect to smoking. Results: In this study, male patients (65.3%) were more common than female patients (34.7%). Among smoker patients, males were more frequent (88.70%) than females (11.29%). The habit of smoking was identified in 51.2% patients. Among demographic factors, there were statistically significant differences in age, smoking and income (p≤0.05) in both patient groups. Most of smoker patients (88.70%) were from low-income families. In terms of education of patients, a non-significant difference was reported (p=0.987). A significant difference was found according to the all HNSCC subsites (p=0.005). The rate of larynx cancer was more in smoker patients (53%) and hypopharynx cancer was more in non-smoker patients (47%). Squamous cell carcinoma (96.6%) was dominant. Regarding clinical features of HNC, the percentage of stage III cancer (54.54%) and moderately differentiated tumour (82.64%) was the highest. Among TNM classification, T3-4, N0 and M0 were more frequent. Conclusion: Smoking may be a key risk factor for HNC in addicts.
Nodal-antinodal dichotomy from pairing disorder in d-wave superconductors

description: We study the basic features of the local density of states (LDOS) observed in STM experiments on high-T$_c$ d-wave superconductors in the context of a minimal model of a d-wave superconductor which has {\it weakly} modulated off-diagonal disorder. We show that the low and high energy features of the LDOS are consistent with the observed experimental patterns and in particular, the anisotropic local domain features at high energies. At low energies, we obtain not only the scattering peaks predicted by the octet model, but also weak features that should be experimentally accessible. Finally, we show that the emerging features of the LDOS lose their correspondence with the features of the imposed disorder, as its complexity increases spatially.
Restrictions on Transversal Encoded Quantum Gate Sets

subject: FOS: Physical sciences

description: Transversal gates play an important role in the theory of fault-tolerant quantum computation due to their simplicity and robustness to noise. By definition, transversal operators do not couple physical subsystems within the same code block. Consequently, such operators do not spread errors within code blocks and are, therefore, fault tolerant. Nonetheless, other methods of ensuring fault tolerance are required, as it is invariably the case that some encoded gates cannot be implemented transversally. This observation has led to a long-standing conjecture that transversal encoded gate sets cannot be universal. Here we show that the ability of a quantum code to detect an arbitrary error on any single physical subsystem is incompatible with the existence of a universal, transversal encoded gate set for the code.
