Subjects: subject: Engineering--Aerospace
subject: Supersonic Combustion
subject: Flow Visualisation
subject: Planar Laser-Induced Fluorescence

description: Flow visualisation and statistical analysis of a supersonic, turbulent reacting flow from non-intrusive hydroxyl radical (OH) planar laser-induced fluorescence (PLIF) images are presented. The OH PLIF images show instantaneous structures of turbulence in two combustor configurations at different fuel equivalence ratios in the University of Virginia Supersonic Combustion Facility (UVaSCF). Proper orthogonal decomposition (POD) and autocorrelations are performed on the OH PLIF data to extract quantitative information about turbulent fluctuations and length scale correlations. Changes in integral length scales and turbulent energy flow patterns are observed as a function of position in the combustor and fuel equivalence ratio. Dual-mode operation with supersonic and subsonic combustion is demonstrated in the facility. This work has been performed in collaboration with other non-intrusive diagnostic techniques in the UVaSCF to develop a comprehensive database for the validation of computational fluid dynamics (CFD) models.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Unitarity and the optical theorem are used to derive the reduced density matrices of Compton scattering in the presence of a witness particle. Two photons are initially entangled wherein one photon participates in Compton scattering while the other is a witness, i.e. does not interact with the electron. Unitarity is shown to require that the entanglement entropy of the witness photon does not change after its entangled partner undergoes scattering. The final mutual information of the electronic and witness particle's polarization is nonzero for low energy Compton scattering. This indicates that the two particles become correlated in spite of no direct interaction. Assuming an initial maximally entangled state, the change in entanglement entropy of the scattered photon's polarization is calculated in terms of Stokes parameters. A common ratio of areas occurs in the final reduced density matrix elements, von Neumann entropies, Stokes parameter, and mutual information. This common ratio consists of the Thomson scattering cross-section and an accessible regularized scattering area.

description: Generalized Bose operators correspond to reducible representations of the harmonic oscillator algebra. We demonstrate their relevance in the construction of topologically non-trivial solutions in noncommutative gauge theories, focusing our attention to flux tubes, vortices, and instantons. Our method provides a simple new relation between the topological charge and the number of times the basic irreducible representation occurs in the reducible representation underlying the generalized Bose operator. When used in conjunction with the noncommutative ADHM construction, we find that these new instantons are in general not unitarily equivalent to the ones currently known in literature.

Subjects: subject: Classical Physics (physics.class-ph)

description: In this article, we use different models to compute displacements and stresses of a simply supported sandwich beam subjected to a uniform pressure. 8-node quadrilateral elements (Plane 82), multi-layered 8-node quadrilateral shell elements (Shell 91) and multi-layered 20-node cubic elements (Solid 46) are used. The influence of mesh refinement and of the ratio of Young's moduli of the layers are studied. Finally, a local Reissner method is presented and assessed, which permits an improvement in the accuracy of interface stresses for a high ratio of Young's moduli of the layers with Plane 82 elements.

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

description: The ANTARES neutrino telescope is installed at a depth of 2.5 km of the Mediterranean Sea and consists of a three-dimensional array of 885 photomultipliers arranged on twelve detector lines. The prime objective is to detect high-energy neutrinos from extraterrestrial origin. Relativistic muons emerging from charged-current muon neutrino interactions in the detector surroundings produce a cone of Cerenkov light which allows the reconstruction of the original neutrino direction. The collaboration has implemented different methods to search for neutrino point sources in the data collected since 2007. Results obtained with these methods as well as the sensitivity of the telescope are presented.

Subjects: subject: Literature--Canadian (English)
subject: Canadian Literature
subject: Postmodern
subject: Creative Writing

description: You are Among Monsters is a novel that obsesses over the need to tell stories. The novel questions the narrative act and undermines the verisimilitude of the patterns that emerge from the urge to organize events into story. Questions of history, fiction, material history, and believability are raised by the novel and its accompanying critical exegesis. The novel has been heavily influenced by theoretical studies into historiographic metafiction, narrative as a source of comfort, storytelling, patternicity, literary post-utopia, and sous rature. These concepts and their relation to the novel are discussed in the exegetic material.
The historical development of intensive care nursing at Vancouver General Hospital, 1960-1985
Creators: name: Hamilton, Deborah
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes the historical development of intensive care nursing in the adult medical and surgical intensive care unit (ICU) at Vancouver General Hospital (VGH) from 1960 until 1985. The ICU was established to group a new, emerging cohort of critically ill patients in one centralized place the hospital. Doctors referred critically ill patients to the ICU, believing the patient would benefit from the continuous nursing care of a bedside nurse in the ICU. The concepts of place and space, specialty nursing education, professionalism, gender, and the expansion of new medical technologies used in critical care, form the central categories for analysis. I examine the broader social, cultural, economic influences, and the hospital context that shaped critical care nursing in Western Canada in the 1960s, using one hospital as a case study. An analysis of the transformation from one-to-one nursing of the most critically ill patients on the general nursing wards, to specialized critical care nursing in the ICU, significantly contributes to the history of nursing. As nurses developed new critical care nursing expertise, their work relationships with other nurses and health professionals changed. As their expertise deepened, nurses integrated new technologies that were introduced into the ICU into their practice. Nurses created critical care nursing theory in a grassroots process using their experiences in critical care, as the foundation. They also formalized this knowledge into a critical care nursing program. This process was not without its tensions, as nursing education was also beginning to make the transition from hospital-based to degree based education. It was a question of where and how the education of critical care nursing would fit in. Oral history accounts from former and practicing nurses and physicians involved in the establishment of the ICU at VGH form the primary source material, augmented by archival hospital and government records, and photographs. The individual experiences of bedside nurses provide a unique lens to understand the evolution of critical care nursing knowledge and practice at VGH in the broader context of critical care nursing history.

Statistical Study of Emerging Flux Regions and the Upper Atmosphere Response
Creators: name: Zhao, Jie
name: Li, Hui
Publisher: name: arXiv
Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We statistically study the property of emerging flux regions (EFRs) and the upper solar atmosphere response to the flux emergence by using data from the Helioseismic and Magnetic Imager (HMI) and the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO). Parameters including the total emerged flux, the flux growth rate, the maximum area, the duration of the emergence and the separation speed of the opposite polarities are adopted to delineate the property of the EFRs. The response of the upper atmosphere is addressed by the response of the atmosphere at different wavelengths (and thus at different temperatures). According to our results, the total emerged fluxes are in the range of (0.44 -- 11.2)$\times10^{19}$ Mx while the maximum area ranges from 17 to 182 arcsec$^2$. The durations of the emergence are between 1 and 12 hours, which are positively correlated to both the total emerged flux and the maximum area. The maximum distances between the opposite polarities are 7 -- 25 arcsec and are also correlated to the duration positively. The separation speeds are from 0.05 to 1.08 km s$^{-1}$, negatively correlated to the duration. The derived flux growth rates are (0.1 -- 1.3)$\times10^{19}$ Mx hr$^{-1}$, which are positively correlated to the total emerging flux. The upper atmosphere responds to the flux emergence in the 1600Å chromospheric line first, and then tens and hundreds of seconds later, in coronal lines, such as the 171Å (T=10$^{5.8}$ K) and 211Å (T=10$^{6.3}$ K) lines almost simultaneously, suggesting the successively heating of atmosphere from the chromosphere to the corona.

description: In this study, I examined how HIV-negative gay men in serodiscordant relationships constructed HIV-negativity and serodiscordance online through their use of language. Using Potter and Wetherell’s (1987) discursive psychological approach, I analyzed 22 online postings, focusing on the linguistic resources HIV-negative partners drew on to talk about serodiscordance and their own HIV-subjectivities, respectively. Based on my analysis of the material, participants organized their talk around two central interpretative repertoires. Specifically, they described their serodiscordant relationship (a) as a form of alliance, and (b) as a site of tensions. I discuss the findings in relation to the existing literature on the topic of serodiscordance among gay couples, and I comment on the limitations of the study, recommendations for researchers, as well as implications for counselling practitioners.

subject: On-Farm

description: The availability of wheat, along with the large amounts of manure produced by the livestock industry in the province of Alberta, presents an interesting opportunity for integration of farm operation with biofuels production in western Canada. Anaerobic co-digestion of manure and the wastewater from ethanol production generates biogas which could be used to produce steam and electricity, as well as digestate for fertilizer. Animal feed is obtained as co-product from ethanol production. In the present study, a conceptual design of a small scale integrated on-farm ethanol plant for the production of 112 L/h of anhydrous ethanol was developed. The process was designed and optimized for low energy consumption using a commercial process simulator. Optimization through heat integration lowered the steam consumption to 3.71 kg per liter of ethanol. The total capital investment for the project was estimated at 4,100,000 CD with a payback period of 5 years and a return on investment of 25%.
Characterization of TPX2 phosphorylation at Threonine 72 in Human cancer cells

description: The Targeting Protein for Xenopus kinesin-like protein 2 (TPX2) is a microtubule-associated protein required for mitotic spindle assembly. In interphase cells, TPX2 regulates the amplification of the -H2AX signal in the nucleus during the DNA damage response. TPX2 functions are likely to be regulated by the putative phosphorylation sites identified by several mass spectrometry-based screenings. However, most of these 41 sites have not been validated and their roles have not been characterized. In my thesis, I characterized the phosphorylation of TPX2 at Threonine 72 (Thr72) in vivo. First, I confirmed the specificity of our homemade phospho-Thr72 antibodies. I then found out that phosphorylation at Thr72 is cell cycle-dependent, peaking at the M phase of the cell cycle. I also confirmed the existence of Thr72 phosphorylation in mitotic HeLa cells by mass spectrometry. Using a pharmacological approach, I discovered that cyclin-dependent kinases can mediate phosphorylation at this site in mitotic HeLa cells. Finally, using TPX2 siRNAs and phospho-mutants, I examined the role of Thr72 in mitotic spindle assembly and DNA damage response. Understanding the significance of phosphorylation of Thr72 may provide new insights into the roles of TPX2 in healthy and diseases conditions, such as cancers.

description: Anomalies are unusual and unexpected events in the network that do not conform to the normal network activity. Accurate and agile anomaly identification is critical for reliable operation of the network. However, identifying complex anomalies within voluminous and diverse network traffic is a challenging task. This problem is further complicated when anomaly detection techniques designed for backbone networks are deployed in edge networks, producing low accuracy and many false alarms. This thesis reports the anomaly detection performance of three techniques in a large edge network. I enhance two backbone network techniques, BasisDetect and PCA, to work in edge networks. I also develop Gradient, a simple gradient-based multi-resolution anomaly detection technique, that performs efficiently in practice. The experiments are performed on a dataset spanning 23 months with periods of high and low network activity. The diverse sets of hosts in the network included servers, wireless devices, and residential users. I assess the detection performance using several metrics, including detection accuracy, robustness, and sensitivity to training sets and traffic volumes. I also analyze the impact of configuration parameters on the performance of anomaly detection techniques. My results show that both BasisDetect and Gradient generally perform with high accuracy in edge networks. BasisDetect lacks robustness over a long period of time but this deficiency can be addressed with periodic retraining. PCA, however, has low detection accuracy and generates many false alarms.

description: Pagellus affinis Boulenger 1888
Common name: Arabian Pandora (Figures 10 & 15 X, Y; Table 1)
 Pagellus affinis Boulenger 1888: 659 (Muscat, Oman, Arabian Sea).
 Diagnosis. Body elongate and slightly compressed, its depth 2.6–3.0 times of SL. Dorsal rays XII, 10; anal rays III, 9–10; pectoral rays 16; lateral line scales 59; scales above lateral line to base of fifth dorsal spine 6½; gill rakers 16, nine on lower arch. Scalation on top of head reaching to beyond vertical diameter of eyes.
 Description. Body elongate, somewhat fusiform; head profile convex from upper lip to origin of dorsal-fin; eyes large, mouth terminal and little protrusible; no scales on preopercular flange, nor on soft dorsal and anal-fins; scalation of top of head reaching to beyond vertical diameter of eyes; sharp teeth, small molars in jaws; dorsal spines slender and thin, fifth longest; last dorsal and anal-fin soft rays a little bit longer than penultimate rays; 2nd and 3rd anal spines subequal; caudal fin forked; pectoral-fins long, reaching to anterior origin of anal-fin. Scaly sheath at base of dorsal and anal fins.
 Colour in fresh specimen. Overall appearance silvery with reddish tinge in most parts of the body. Reddish colour in snout part of the head; pinkish or reddish and silvery in colour combination with a light blue spotted lines running along the scale-lines above and below the lateral line.
 Distribution. Western Indian Ocean including, Persian Gulf to the Gulf of Aden and northern coast of Somalia, as far western coast of India and Pakistan.
 Remarks. The species Pagellus affinis was first recorded from Pakistan by Amir et al. (2013). The single specimen of P. affinis (CEMB-P 2012–00078, 183 mm SL) shows nine anal-fin rays, while the comparative Omani specimens of P. affinis (MUFS 33502–33506, 33668, 33670–33671, 8 specimens, 188–232 mm SL) and of other workers (Bauchot & Smith, 1983; Randall, 1995) indicated 10 anal-fin rays for this species. The nine counts of anal-fin rays in the Pakistani specimen will require examination of additional specimens from this region to further elaborate on this character as either character variation or the presence of a new isolated population in this region. Lacking additional specimens from our region, we cannot provide a direct comparison of our specimen on the basis of this single character.

description: We study a surface defect in the free and critical $O(N)$ vector models, defined by adding a quadratic perturbation localized on a two-dimensional subspace of the $d$-dimensional CFT. We compute the beta function for the corresponding defect renormalization group (RG) flow, and provide evidence that at long distances the system flows to a nontrivial defect conformal field theory (DCFT). We use epsilon and large $N$ expansions to compute several physical quantities in the DCFT, finding agreement across different expansion methods. We also compute the defect free energy, and check consistency with the so-called $b$-theorem for RG flows on surface defects.

description: The Pierre Auger Collaboration discovered, in a solid angle of radius about 18\degree, a local group of cosmic rays having energies in the region E0 \geq 5.5\times1019 eV and coming from the region of the Gen A radio galaxy, whose galactic coordinates are lG = 309.5\degree and bG = 19.4\degree. Near it, there is the Centaur supercluster of galaxies, its galactic coordinates being lG = 302.4\degree and bG = 21.6\degree. It is noteworthy that the Great Attractor, which may have a direct bearing on the observed picture, is also there.
First direct mass measurement of the two and four neutron halos ⁶He and ⁸He using the TITAN Penning trap mass spectrometer
Creators: name: Brodeur, Maxime
Publisher: name: University of British Columbia
Year: 2010

description: Neutron halo nuclei are distinguished by an extended matter radius and a small neutron separation energy compared to other nuclei. They are comprised of a core surrounded by at least one loosely bound neutron forming a halo structure. The size of the core is associated with the charge radius while the extent of the diffuse halo region, owing to quantum mechanical leakage of the valence neutron(s) wavefunction, depends exponentially on their separation energy. Predicting accurately the extreme behaviour of these nuclei is challenging for nuclear theory. These nuclei provide an ideal testing grounds of nuclear theory, leading to a deeper understanding of the strong force and nuclear interactions. Halo nuclei can be found amongst light nuclei and hence have few (A~10) nucleons. This makes them treatable using ab-initio methods. To test these theoretical approaches and consequently refine our knowledge of the nucleus, one requires both precise and accurate experimental data, such as ground state properties: masses (or separation energies) and sizes (charge and matter radii). In this thesis we present the mass measurement of the two- and four-neutrons halo ⁶,⁸He (t₁/₂ = 808 ms, 119 ms respectively) using the TITAN Penning trap as well as systematic studies of this system. The obtained mass are m(⁶He) = 6 018 885.883(57) u and m(⁸He) = 8 033 934.435(114) u. These values show deviations with literature of 4.0 and 1.7σ. Using our new masses, we re-evaluated the charge radius and obtained (rc²)¹/²(⁶He) = 2.056(10) fm and (rc²)c¹/²(⁸He) = 1.955(18) fm, which correspond to an improvement in the precision of 9% and 36% respectively. Using the charge radii and the binding energies of ⁶,⁸He, obtained from our more precise and accurate masses, we show that one can test the predictions of advanced ab-initio nuclear theories for these extreme systems. Using such comparison, we point to the needs of three-body interactions in order to explain the experimental observables.
Muscle and fascicle excursion in children with Cerebral Palsy and the effects of Botox on passive muscle properties

description: Cerebral Palsy (CP) is a non-progressive disorder caused by a lesion in the brain. Spasticity and passive muscle stiffness are common symptoms which lead to joint contractures and functional impairments. Fascicle length, and muscle- and fascicle excursions were compared between children with CP and typically developing (TD) children. Fascicles were found to be shorter and relative muscle- and fascicle excursions were greater in children with CP compared to TD children. We concluded that short fascicles and great fascicle excursions could be a contributing factor to muscle weakness and joint contractures in children with CP. Botulinum Toxin Type-A (Botox) is used to reduce spasticity in children with CP, but the effects of Botox on passive muscle stiffness are not clear. We found no difference in passive muscle stiffness before and five days following Botox injection. We concluded that it is important to distinguish between passive stiffness and spasticity before Botox is used to treat children with CP.

description: We present READMem (Robust Embedding Association for a Diverse Memory), a modular framework for semi-automatic video object segmentation (sVOS) methods designed to handle unconstrained videos. Contemporary sVOS works typically aggregate video frames in an ever-expanding memory, demanding high hardware resources for long-term applications. To mitigate memory requirements and prevent near object duplicates (caused by information of adjacent frames), previous methods introduce a hyper-parameter that controls the frequency of frames eligible to be stored. This parameter has to be adjusted according to concrete video properties (such as rapidity of appearance changes and video length) and does not generalize well. Instead, we integrate the embedding of a new frame into the memory only if it increases the diversity of the memory content. Furthermore, we propose a robust association of the embeddings stored in the memory with query embeddings during the update process. Our approach avoids the accumulation of redundant data, allowing us in return, to restrict the memory size and prevent extreme memory demands in long videos. We extend popular sVOS baselines with READMem, which previously showed limited performance on long videos. Our approach achieves competitive results on the Long-time Video dataset (LV1) while not hindering performance on short sequences. Our code is publicly available.

description: Radio frequency isolators based on ferrite junction circulators have been the dominant isolator technology for the past fifty years, yet they have not been integrated practically because ferrites are generally incompatible with semiconductor processes and their size is inversely proportional to their operating frequency. Hall isolators are another approach whose operating frequency is independent of their size, are compatible with semiconductor processes and are thus appropriate for integration. Through simulation, this thesis demonstrates that these devices can be on the order of microns in size and have a bandwidth from DC to over a terahertz. Measurements of an unoptimized Hall element demonstrate an operating bandwidth from DC to 1127 MHz. A technique using multi-contact Hall plates is shown to reduce isolator insertion loss to 0.89 dB, which is competitive with ferrite-based devices.

We analyze the pixel color-magnitude diagram (pCMD) of NGC 5195, focusing on the properties of its red and blue pixel sequences and the difference from the pCMD of NGC 5194 (M51A; the spiral galaxy interacting with NGC 5195). The red pixel sequence of NGC 5195 is redder than that of NGC 5194, which corresponds to the difference in the dust optical depth of 2 15. Along the tidal bridge, young populations seem to be clumped particularly at the middle point of the bridge. On the other hand, the dusty population shows a relatively wide distribution between the tidal bridge and the NGC 5195 center.

description: Massive neutrinos are well-known to cause a characteristic suppression in the growth of structures at scales below the neutrino free-streaming length. A detailed understanding of this suppression is essential in the era of precision cosmology we are entering into, enabling us to better constrain the total neutrino mass and possibly probe (beyond)-$Λ$CDM cosmological model(s). Instead of the usual N-body simulation or Boltzmann solver, in this article we consider a two-fluid framework at the linear scales, where the neutrino fluid perturbations are coupled to the CDM (+ baryon) fluid via gravity at redshifts of interest. Treating the neutrino mass fraction $f_ν$ as a perturbative parameter, we find solutions to the system with redshift-dependent neutrino free-streaming length in $Λ$CDM background via two separate approaches. The perturbative scale-dependent solution is shown to be in excellent agreement with numerical solution of the two-fluid equations valid to all orders in $f_ν$, and also agrees with results from {\texttt{CLASS}} to a good accuracy. We further generalize the framework to incorporate different evolving dark energy backgrounds and found sub-percent level differences in the suppression, all of which lie within the observational uncertainty of BOSS-like surveys. We also present a brief discussion on the prospects of the current analysis in the context of upcoming missions.

description: Non-photic stimuli are capable of producing large phase advances of the suprachiasmatic nuclei (SCN) during the midday in a manner that is different than light. Two prominent non-photic stimuli include confinement to a novel running wheel, and sleep deprivation by gentle handling. It was hypothesized that these stimuli both provide a sustained level of behavioral arousal to the animals in order to bring about phase shifts. If this was the case, then neurotransmitters involved in behavioral arousal should also participate in non-photic phase shifting. Neurotransmission of acetylcholine (ACh) is involved in bringing about arousal and also has been shown to play a role in the circadian system. The purpose of these experiments was to determine if ACh plays a role in non-photic phase shifting and to what extent arousal is involved. First, it was shown that Fos expression is increased in general areas containing ACh, orexin and histamine in Syrian hamsters undergoing sleep deprivation. Next, it was found that Fos expression specifically in cholinergic cells of the forebrain is increased in animals undergoing novel wheel confinement, but not sleep deprivation. It was then found that in vivo electrical stimulation of the basal forebrain region containing cholinergic neurons phase advanced circadian rhythms of wheel running activity at midday. The phase shifts to these stimulations was found to be dependent on a direct cholinergic input into the SCN. Finally, it was shown that blocking cholinergic neurotransmission in the SCN attenuates phase advances to novel wheel confinement. Taken together, these results show that ACh participates in non-photic phase shifting of the SCN through direct projections from forebrain cells. This also provides evidence for a role of behavioral arousal in novel wheel confinement induced phase shifts and a system that can feedback information on behavioral state onto the SCN.

description: We present experimental measurements of the electronic contribution to the Raman spectra of individual metallic single-walled carbon nanotubes (MSWNTs). Photoexcited carriers are inelastically scattered by a continuum of low-energy electron-hole pairs created across the graphenelike linear electronic subbands of the MSWNTs. The optical resonances in MSWNTs give rise to well-defined electronic Raman peaks. This resonant electronic Raman scattering is a unique feature of the electronic structure of these one-dimensional quasimetals.
The role of 'mzungu' voluntourism in schools and community development in rural Mukono, Uganda

description: Uganda introduced Universal Primary Education (UPE) in 1997 and while the number of children in school has increased, the quality has not. Fifteen years on UPE schools struggle with teacher absenteeism, overcrowded classrooms, and high repetition and drop-out rates. Community members have now started their own low-cost private schools (LCPS) which have nominal school fees, lower student/teacher ratios, and (the majority) seek out children most in need. This research explores the partnership between LCPSs and volunteer organizations. It provides a critical bridge to divergent literatures on LCPSs and the voluntourism industry through Rights Based Development (RBD). The research objectives are examined within the framework of pro-poor tourism and demonstrate how this partnership contributes to community development. The mixed-methods comparative case study was carried out in Mukono District, Uganda, in 2010. Five LCPSs partnered with a volunteer NGO, The Real Uganda (TRU), was the setting for this fieldwork and offered an insight to the success of these schools and partnerships. It further revealed the role of western volunteers as education boosters through their presence in host schools and communities. Two of the five schools in this research now have the highest Primary Leaving Exam (PLE) rates in their district. These schools have now gained notoriety and parents are becoming more engaged in their children’s education. The success of these LCPSs offers an alternative to the failing government schools and strategies put forward by international education organizations. However, the perils of this partnership and the impacts of bzungu in host communities was also seen, leading to parental and community mistrust; and in the worst scenario, the closure of a school.

description: Despite the use of myeloablative therapy, the prognosis of patients with high-risk neuroblastoma remains poor. More targeted therapies are required reduce the toxicity and increase the cure rate for these young patients. Oncolytic viruses have been shown to be selective and effective at targeting a wide variety of malignant cells by exploiting aberrant signaling pathways and many viruses have been translated into the clinical setting with positive results. In this study, the oncolytic viruses myxoma and vesicular stomatitis virus, previously shown to be effective against other neural crest derived tumors, were examined. Neuroblatoma cell lines and patient-derived neuroblastoma TICs were used in our in vitro and in vivo models to evaluate the selectivity and efficacy OV therapy. This pre-clinical study provides evidence that myxoma and VSV are able to selectively target and kill neuroblatoma cells, leading to reduced tumor growth in vivo. These findings support further investigation into the use of OVs as an adjunct to the current standard for patients with high-risk neuroblasomta.

description: We present the full results of the Wuppertal-Budapest lattice QCD collaboration on flavor diagonal and non-diagonal quark number susceptibilities with 2+1 staggered quark flavors, in a temperature range between 125 and 400 MeV. The light and strange quark masses are set to their physical values. Lattices with Nt=6, 8, 10, 12, 16 are used. We perform a continuum extrapolation of all observables under study. A Symanzik improved gauge and a stout-link improved staggered fermion action is utilized. All results are compared to the Hadron Resonance Gas model predictions: good agreement is found in the temperature region below the transition.

Solving anharmonic oscillator with null states: Hamiltonian bootstrap and Dyson-Schwinger equations

description: As basic quantum mechanical models, anharmonic oscillators are recently revisited by bootstrap methods. An effective approach is to make use of the positivity constraints in Hermitian theories. There exists an alternative avenue based on the null state condition, which applies to both Hermitian and non-Hermitian theories. In this work, we carry out an analytic bootstrap study of the quartic oscillator based on the small coupling expansion. In the Hamiltonian formalism, we obtain the anharmonic generalization of Dirac's ladder operators. Furthermore, the Schrodinger equation can be interpreted as a null state condition generated by an anharmonic ladder operator. This provides an explicit example in which dynamics is incorporated into the principle of nullness. In the Lagrangian formalism, we show that the existence of null states can effectively eliminate the indeterminacy of the Dyson-Schwinger equations and systematically determine $n$-point Green's functions.
