description: Bilingual article. (En / Eo)

In this paper an evaluation of the contribution to philosophical investigation by Alan Turing is provided in terms of creation of Artificial Languages (ALs). After a discussion of the term AL in the literature, and in particular within the theoretical model offered by Lyons, the legacy of Turing is presented with a special attention to what remains after a century by his birth and what is still to be investigated in this area.

description: Ultrasound-stimulated microbubble (USMB) therapy has proven efficacy of targeting tumor vasculature and enhancing the effect of radiation in tumor xenografts. In this investigation, we studied whether this treatment enhances the sensitivity of cervical cancer to radiation. Human cervical cancer (ME-180 and SiHa) cells were treated with USMB or exposed to radiation (0, 2, 4, 6 and 8 Gy) or radiation (8 Gy) in combination with USMB. Clone formation assay and CCK-8 assay were used to analyze the proliferation capacity of cells. Apoptosis and DNA double-strand breaks were detected using flow cytometry and immunofluorescence staining of gamma-H2AX (γ-H2AX), respectively. Matrigel tubule formation was performed to evaluate the angiogenesis of human umbilical vein endothelial cells. In xenograft model of SiHa cells, tumor tissue expression of CD31 was detected by immunohistochemistry. USMB and radiation synergistically restrained the growth of ME-180 and SiHa cells. USMB promoted radiation-induced apoptosis by enhancing the levels of proapoptotic proteins. Furthermore, USMB enhanced radiation-induced γ-H2AX foci to induce DNA double-strand breaks in cervical cancer cells. USMB in combination with radiation reduced the angiogenic capacity of endothelial cells in vitro. Moreover, USMB strengthened the inhibitory effect of radiation on tumor growth and angiogenesis in xenograft models. In conclusion, USMB exposure effectively enhanced the destructive effect of radiation on cervical cancer, suggesting that USMB might be a promising sensitizer of radiotherapy to treat cervical cancer.

description: In the framework of a Chiral effective theory with dibaryon fields, we calculate the pion mass dependence of the inverse scattering length of the nucleon-nucleon system in the $^3S_1$ channel at order ${(m_π^3 / Λ_χ^2)}\times (m_π^{1/2}m_N^{3/2}/8πf_π^2)^n$ for all $n\ge 0$. We show that certain sets of potentially large higher order contributions vanish. We discuss the difficulties of extending the proof to the $^1S_0$ channel. We apply our results to chiral extrapolations of current lattice data.

Exploring multiple-mode vibrations of capacitive micromachined ultrasonic transducers (CMUTs)
Creators: name: You, Wei
Publisher: name: University of British Columbia
Year: 2013

description: Capacitive Micromachined Ultrasonic Transducers (CMUTs) are considered advantageous over piezoelectric transducers for ultrasound imaging for the high bandwidth, ease of integration with electronics and miniaturization. Research efforts over the past two decades have been focusing on manufacturing and system integration of CMUTs to achieve comparable and better performance than the piezoelectric counterparts, while the uniqueness of the CMUT structure and physics is barely exploited. This thesis explores the complex behavior of CMUTs from a mode superposition perspective, and demonstrates imaging applications using CMUTs' multi-modal operation. The operation of CMUTs is first analytically modeled as a coupled electro-mechano-acoustical system using plate vibration theory. As the simplest case, the first symmetric and asymmetric modes of vibration can be excited simultaneously via asymmetric electrostatic actuation, resulting in a vibration profile with a shifted center. Finite element modeling (FEM) is used to verify the theoretical calculation, and an equivalent circuit consisting of two sub-circuits for the symmetric and asymmetric vibration modes is built to show the possibility of fast simulation of complex CMUT array behavior. Experimental characterization of fabricated CMUT chips show that asymmetric vibration can be achieved with multi-electrode CMUTs. Two imaging applications using the multi-modal operation of CMUTs are proposed. The first concept, tiltable transducers, explores the benefits of orienting each transducer element toward the focal point to concentrate the acoustic energy and reduce grating lobes and side lobes. Imaging simulation shows the grating lobes can be reduced by 20dB while the main lobe energy is preserved. FEM simulation demonstrates that CMUTs capable of asymmetric vibration can be a viable candidate as tiltable transducers with careful design of the cell dimension and central frequency. The second imaging application takes advantage of the ringing response of a CMUT to off-axis acoustic sources to achieve super-resolution imaging with low computational cost. The differential responses across all CMUT cells form a more decorrelated pattern than the regular average responses, which leads to better estimation performance of the proposed super-resolution algorithm. While only preliminary experimental results for the proposed applications are presented, the multi-modal operation concept shows potential in improving several aspects of ultrasound imaging.

description: We consider a class of inverse problems defined by a nonlinear map from parameter or model functions to the data. We assume that solutions exist. The space of model functions is a Banach space which is smooth and uniformly convex; however, the data space can be an arbitrary Banach space. We study sequences of parameter functions generated by a nonlinear Landweber iteration and conditions under which these strongly converge, locally, to the solutions within an appropriate distance. We express the conditions for convergence in terms of Hölder stability of the inverse maps, which ties naturally to the analysis of inverse problems.

description: Radiation cystitis (RC) is a complex and common complication after radiotherapy for pelvic cancer. Icariside II (ICAII) is a flavonoid compound extracted from Epimedium, a traditional Chinese medicine, with various pharmacological activities. The aim of the present study was to investigate the cysto-protective effects of ICAII in RC rats and its possible mechanisms. A rat model of induced radiation cystitis using pelvic X-ray irradiation was used, and bladder function was assessed by bladder volume and bladder leakage point pressure (LPP) after ICAII treatment. HE and Masson stains were used to assess the histopathological changes in the bladder. IL-6, TNF-α, IL-10, IL-4 and IL-1β were measured by ELISA to assess the level of inflammation. The gene-level changes in ICAII-treated RC were observed by transcriptome sequencing, and then the potential targets of action and biological mechanisms were explored by PPI, GO and KEGG enrichment analysis of the differentially expressed genes. Finally, the predicted targets of action were experimentally validated using immunohistochemistry, RT–qPCR, molecular docking and CETSA. ICAII significantly increased bladder volume and the LPP, ameliorated pathological damage to bladder tissues, decreased the levels of IL-6, TNF-α, and IL-1β, and increased the levels of IL-10 and IL-4 in radiation-injured rats. A total of 90 differentially expressed genes were obtained by transcriptome sequencing, and PPI analysis identified H3F3C, ISG15, SPP1, and LCN2 as possible potential targets of action. GO and KEGG analyses revealed that these differentially expressed genes were mainly enriched in the pathways metabolism of xenobiotics by cytochrome P450, arachidonic acid metabolism, Staphylococcus aureus infection and chemical carcinogenesis - reactive oxygen species. Experimental validation showed that ICAII could significantly increase the expression of H3F3C and ISG15 and inhibit the expression of SPP1 and LCN2. ICAII binds well to H3F3C, ISG15, SPP1 and LCN2, with the best binding ability to H3F3C. Furthermore, ICAII inhibited the protein degradation of H3F3C in bladder epithelial cells. ICAII may alleviate the bladder inflammatory response and inhibit the fibrosis process of bladder tissues through the regulation of H3F3C, ISG15, SPP1, and LCN2 targets and has a protective effect on the bladder of radioinjured rats. In particular, H3F3C may be one of the most promising therapeutic targets.

The Role of Structured Magnetic Fields on Constraining Properties of Transient Sources of Ultra-high-energy Cosmic Rays

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We study how the properties of transient sources of ultra-high-energy cosmic rays (UHECRs) can be accessed by exploiting UHECR experiments, taking into account the propagation of UHECRs in magnetic structures which the sources are embedded in, i.e., clusters of galaxies and filamentary structures. Adopting simplified analytical models, we demonstrate that the structured extragalactic magnetic fields (EGMFs) play crucial roles in unveiling the properties of the transient sources. These EGMFs unavoidably cause significant delay in the arrival time of UHECRs as well as the Galactic magnetic field, even if the strength of magnetic fields in voids is zero. Then, we show that, given good knowledge on the structured EGMFs, UHECR observations with high statistics above $10^{20}$ eV allow us to constrain the generation rate of transient UHECR sources and their energy input per burst, which can be compared with the rates and energy release of known astrophysical phenomena. We also demonstrate that identifying the energy dependence of the apparent number density of UHECR sources at the highest energies is crucial as a clue to such transient sources. Future UHECR experiments with extremely large exposure are required to reveal the nature of transient UHECR sources.

description: The celebrated Hajnal-Szemerédi theorem gives the precise minimum degree threshold that forces a graph to contain a perfect K_k-packing. Fischer's conjecture states that the analogous result holds for all multipartite graphs except for those formed by a single construction. Recently, we deduced an approximate version of this conjecture from new results on perfect matchings in hypergraphs. In this paper, we apply a stability analysis to the extremal cases of this argument, thus showing that the exact conjecture holds for any sufficiently large graph.

Grazie alla sua plasticità semantica sembra essere evocato ogni qual volta venga posta la domanda sull’origine dell’uomo. Sotto numerosi punti di vista, infatti, può apparire come simbolo dei simboli in virtù della sua predisposizione a rappresentare ogni sorta di dualità essenziale, al di là della semplice polarità sessuale. Viene gelo-samente custodito nel seno di ogni cultura proprio perché la sua indicibi-le natura appartiene a ogni uomo: si plasma con la medesima materia, onirica e impalpabile, di cui è fatto l’inconscio.

description: We discuss a possible dependence of the chiral magnetic effect (CME) on the elliptic flow coefficient v2. We first study this in a hydrodynamic model for a static anisotropic plasma with multiple anomalous U(1) currents. In the case of two charges, one axial and one vector, the CME formally appears as a first-order transport coefficient in the vector current. We compute this transport coefficient and show its dependence on v2. We also determine the CME-coefficient from first-order corrections to the dual AdS background using the fluid-gravity duality. For small anisotropies, we find numerical agreement with the hydrodynamic result.

description: Purpose: To determine the extent to which Occupational Therapists (OTs) in Nova Scotia (NS) conduct wheelchair skills training, the nature of training and the OTs’ perceptions on training. Materials and methods: Anonymous online survey. Results: We received 110 responses from OTs living in NS and involved in direct patient care, 96 (93%) of whom reported helping clients obtain manual wheelchairs. Of the OTs who responded to the question “…do you typically provide wheelchair-skills training…?”, 40 (43.5%) answered “Yes, usually” for clients and 40 (46.0%) for caregivers. The median duration of training sessions for clients and caregivers was 30 and 20 min; the median number of sessions was 2 and 1. Regarding the importance of training, 65 (73.9%) OTs answered “Very important” and 22 (25%) “Somewhat important” for clients and 55 (64.0%) answered “Very important” and 29 (33.7%) “Somewhat important” for caregivers. About one-third of OTs considered themselves adequately prepared for the trainer role. A variety of barriers and facilitators to training were identified. Trainers were significantly more likely than non-trainers to consider wheelchair skills training as important (p = .0003 for clients and p = .0039 for caregivers) and to consider themselves adequately prepared for the trainer role (p = .002 for clients and .003 for caregivers). Conclusions: Only a minority of NS OTs usually provide wheelchair-skills training for clients or their caregivers and the training provided is minimal, despite a majority who consider such training to be important. Only about one-third of OTs feel prepared for the training role.Implications for rehabilitationOnly a minority of Occupational Therapists (OTs) in Nova Scotia, Canada usually provide wheelchair-skills training for clients or their caregivers.The training that is provided is minimal.A majority of OTs consider such training to be important.Only about one-third of OTs feel prepared for the training role.

Elementi per un’estetica dell’immagine egizia
Creators: name: Bellini, Manuele
Publisher: name: Università degli Studi di Milano
Year: 2010

description: L’immagine egizia, che si declina nelle forme dell’arte e nella scrittura geroglifica, non è né rappresentazione o imitazione della natura né e-spressione, ma creazione di una realtà altra parallela a quella sensibile: la sua funzione è performativa. L’immagine, lungi dall’essere phantasma, vive di per sé ed è una realtà concreta da usarsi, non una realtà trasfigu-rata da fruirsi. È un simulacro che va a supplire l’oggetto cui somiglia –un esempio è dato dalle libagioni dipinte sulle stele funerarie. Fine dell’artista non è la mimesis, ma la ricostruzione, secondo un canone, di una realtà differente, che si anima per magia. L’immagine nasce nella sepoltura e il suo fine non è solo il tramandare la memoria del defunto, ma prolungare la vita: la morte, tradotta in immagine, non solo ricorda la vita che è stata, ma torna a essere vita e l’invisibile, non più confinato nel regno degli inferi e delle ombre, si fa visibile, mostrando la sua mai perduta realtà. Ora, l’assenza di una dialettica tra immagine e realtà impedisce la fioritura di una riflessione filosofica, di un pensiero astratto, perché ciò che i geroglifici, che sono pittogrammi fonetici, indicano trapassa subito nell’oggetto senza che possa costituirsi come concetto. Tuttavia, a gli egizi questo non interessa: l’immagine, ipostatizzando ciò che designa, lo sacralizza perché essa è al servizio di un’ideologia. Ma sacralizzare non è solo propagandare, bensì inserire un oggetto nell’ordine del cosmo, prolungando l’opera di creazione del Demiurgo che la società si sforza di mantenere attraverso l’azione del Faraone.

title: DEPRECATED: An Investigation of the Contingent Negative Variation Using Signal Processing Methods
Creators: name: Nichols, Martin John
Publisher: name: University of Plymouth
Year: 1982

description: The Contingent Negative Variation (CNV) is one of many types of electrical response signals which appear in the electroencephalogram (EEG) of man subsequent to one or more stimuli. Generally these responses are small in comparison to the normal background EEG and had always been thought to consist of a response component which was added to the background EEG. Professor B. McA. Sayers of Imperial College suggested that the auditory response might actually be due to a temporary ordering of the phases of the components of the background EEG. A model, allowing for additive and ordering effects, is proposed here. This model was tested on both auditory and CNV responses using statistical tests not previously used in evoked potential studies. The tests showed that while the additive model satisfactorily described the auditory responses, it did not explain the CNV responses so well. However, both sets of responses showed a certain amount of phase ordering and this was consistent with the model which showed that a repetitive additional component would always incorporate the phase ordering effect. In the absence of detectable additivity pure phase re-ordering might alternatively occur as proposed by Sayers. The CNV's of a patient group were also studied and certain tests are proposed as a possible method of diagnosis. The reliability of these tests was not conclusively proved as much larger control and patient groups would be required to do this. An important part of this work involved the introduction of a quantitative method for assessing the effectiveness of methods of removing eye movement artefact from the EEG. This allowed the development of a more extensive correction method which was tested against two other techniques and found to be superior. This correction method will provide the basis for further research and the development of a corrector to be made commercially.

A 3% Determination of $H_0$ at Intermediate Redshifts

description: Recent determinations of the Hubble constant, H_0, at extremely low and very high redshifts based on the cosmic distance ladder (grounded with trigonometric parallaxes) and a cosmological model (applied to Planck 2013 data) respectively, are revealing an intriguing discrepancy (nearly 9% or 2.4sigma) that is challenging astronomers and theoretical cosmologists. In order to shed some light on this problem, here we discuss a new determination of H_0 at intermediate redshifts (z ~ 1), using the following four cosmic probes: (i) measurements of the angular diameter distances (ADD) for galaxy clusters based on the combination of Sunyaev-Zeldovich effect and X-ray data (0.14 < z < 0.89$), (ii) the inferred ages of old high redshift galaxies (OHRG) (0.62 < z < 1.70), (iii) measurements of the Hubble parameter H(z) (0.1 < z < 1.8), and (iv) the baryon acoustic oscillation (BAO) signature (z=0.35). In our analysis, assuming a flat LCDM cosmology and considering statistical plus systematic errors we obtain H_0 = 74.1^{+2.2}_{-2.2} km/s.Mpc (1sigma) which is a 3% determination of the Hubble constant at intermediate redshifts. We stress that each individual test adopted here has error bars larger than the ones appearing in the calibration of the extragalactic distance ladder. However, the remarkable complementarity among the four tests works efficiently in reducing greatly the possible degeneracy on the space parameter (Omega_m,h) ultimately providing a value of H_0 that is in excellent agreement with the determination using recessional velocities and distances to nearby objects.

description: We investigate theoretically the prospects for using a magnetic nanoelectromechanical single-electron tunneling (NEM-SET) device as an electronic spin filter. We find that strong magnetic exchange forces on the net spin of the mobile central dot of the NEM-SET structure lead to spin-dependent mechanical displacements ("spin polarons"), which give rise to vastly different tunnelling probabilities for electrons of different spin. The resulting spin polarization of the current can be controlled by bias and gate voltages and be very close to 100% at voltages and temperatures below a characteristic correlation energy set by the sum of the polaronic and Coulomb blockade energies.

The role of fibroblast phenotype and pericellular matrix in wound healing
Creators: name: Mah, Wesley Brandon
Publisher: name: University of British Columbia
Year: 2013

description: Scar formation as a result of wound healing in skin is associated with increased deposition of extracellular matrix (ECM) and reduced ECM turnover by fibroblasts. Remarkably, wound healing in the human oral mucosa results in scarless healing, while wound healing in the skin can often result in scarring. Therefore comparing fibroblast phenotype and interactions with their ECM niche in the gingiva and skin may provide novel information about the factors that regulate scar formation. To this end, a novel 3D cell culture model was utilized to yield a cellular microenvironment (niche) that closely mimics the in vivo situation and primary gingival (GFBL) and skin fibroblasts (SFBL) phenotype was characterized. Furthermore, fibroblasts were reseeded on cell-free 3D ECM derived from GFBL and SFBL and the effects of the 3D ECM on cell phenotype were analyzed. Interestingly, SFBL in 3D cultures had greater expression of ECM deposition associated genes, including collagens, matricellular proteins, SLRPs, TGF-β1 and CTGF, intracellular ECM degradation and myofibroblast differentiation and function-associated genes, while GFBL had a greater expression of matrix remodeling associated genes (MMPs). We also found that the 3D cultures showed a significant difference in expression of certain genes (MMPs and myofibroblast function-associated genes) between GFBL and SFBL compared to cells reseeded on the 3D ECM or 2D control substrate. Thus, the 3D culture conditions may differentially regulate expression of a subset of genes in these cells. Interestingly, SFBL had a greater expression of matrix deposition associated genes (collagens, SLRPs, tenascins) irrespective of the culture conditions, suggesting that expression of these genes is inherently distinct between GFBL and SFBL. This was associated with greater autogenous TGF-β expression and SMAD3 phosphorylation in SFBL than GFBL, which may partly explain the innate difference in gene expression. In addition, there was greater ERK1/2 phosphorylation in fibroblasts when seeded on 3D ECM compared to 2D substrate. Greater ERK1/2 phosphorylation may have promoted greater expression of AP-1-dependent MMPs seen in SFBL and GFBL on 3D ECM. In conclusion, reduced expression of matrix deposition associated genes and greater expression of matrix remodeling genes in GFBL may contribute to scarless healing in gingiva.

Kinetic Equations Governing Smoluchowski Dynamics in Equilibrium

description: We continue our study of the statistical properties of particles in equilibrium obeying Smoluchowski dynamics. We show that the system is governed by a kinetic equation of the memory function form and that the memory function is given by one of the self-energies available via perturbation theory as introduced in previous work. We determine the memory function explicitly to second-order in an expansion in a pseudo-potential. The method we use allows for a straightforward computation of corrections via a formal expansion and we therefore view it as an improvement over the conventional mode-coupling theory (MCT) formalism where it is not clear how to make systematic corrections. In addition, the formalism we have introduced is flexible enough to allow for a wide array of different approximation schemes, including density expansions. The convergence criteria for our formal series are not worked out here, but the second order equation that we derive is promising in the sense that it leads to analytic and numerical results consistent with expectations from computer simulations of the hard sphere system in addition to replicating the desired features from conventional MCT (e.g., a two-step decay). These particular solutions will be discussed in forthcoming work.

Arc spaces and the vertex algebra commutant problem

description: Given a vertex algebra $\mathcal{V}$ and a subalgebra $\mathcal{A}\subset \mathcal{V}$, the commutant $\text{Com}(\mathcal{A},\mathcal{V})$ is the subalgebra of $\mathcal{V}$ which commutes with all elements of $\mathcal{A}$. This construction is analogous to the ordinary commutant in the theory of associative algebras, and is important in physics in the construction of coset conformal field theories. When $\mathcal{A}$ is an affine vertex algebra, $\text{Com}(\mathcal{A},\mathcal{V})$ is closely related to rings of invariant functions on arc spaces. We find strong finite generating sets for a family of examples where $\mathcal{A}$ is affine and $\mathcal{V}$ is a $βγ$-system, $bc$-system, or $bcβγ$-system.

description: We examine the possibility that energetic Standard Model particles contained in the jets produced by active galactic nuclei (AGN) may scatter off of the dark matter halo which is expected to surround the AGN. In particular, if there are nearby states in the dark sector which can appear resonantly in the scattering, the cross section can be enhanced and a distinctive edge feature in the energy spectrum may appear. We examine bounds on supersymmetric models which may be obtained from the Fermi Gamma-ray Space Telescope observation of the nearby AGN Centaurus A.
