description: We consider an alloy type potential on an infinite metric graph. We assume a covering condition on the single site potentials. For random Schrödingers operator associated with the alloy type potential restricted to finite volume subgraphs we prove a Wegner estimate which reproduces the modulus of continuity of the single site distribution measure. The Wegner constant is independent of the energy.

description: В статье приводится анализ современных тенденций в области правового регулирования анонимности в сети Интернет, описываются юридические и организационно-технологические проблемы обеспечения анонимности. Автор исследует подходы к анонимности пользователей, сложившиеся в международном праве, в законодательстве и правоприменительных актах отдельных стран, в том числе в России. Делается вывод, что сегодня в Интернете не существует абсолютной анонимности или конфиденциальности. Анонимность в Интернете является относительной и условной. При этом правительства разных стран и глобальные технологические компании стремятся обеспечить себе доступ к максимально возможному объему данных о пользователях глобальной Сети. Несмотря на это, анонимность продолжает рассматриваться в качестве важной юридической гарантии реализации многих прав человека, в числе которых право на имя, неприкосновенность частной жизни, тайну корреспонденции, свободное выражение мнения. В этих условиях важным направлением правового регулирования является закрепление баланса между анонимностью и открытостью в ходе интернет-коммуникаций, а также установление надлежащих юридических процедур раскрытия данных о пользователях и эффективных судебных гарантий в связи с раскрытием таких данных.
description: The article analyzes the contemporary tendencies in the field of legal regulations of anonymity on the Internet, describes legal and organizational and technological problems of ensuring anonymity. The author analyzes the approaches to the users’ anonymity that were developed in the international law, legislation and judgments of various countries, including Russia. It is concluded that today the Internet does not provide the full anonymity and confidentiality. The anonymity in the Internet is relative and conditional. At the same time, governments of the various countries and global technological companies aim to provide the access to the maximum possible amount of data about the Internet users. However, despite this, the anonymity is still considered as an important legal guarantee of ensuring many human rights, including right for a name, inviolability of private life, privacy of correspondence, and free expression of opinions. In such conditions, the establishment of balance between anonymity and openness during Internet communications, as well as establishment of proper legal procedures to disclose the users data and effective court guarantee related to the disclosure of such data are the important direction of legal regulation.

description: It was argued in literature that traversable wormholes can exist with arbitrarily small violation of null energy conditions. We show that if the amount of exotic material near the wormhole throat tends to zero, either this leads to a horn instead of a wormhole or the throat approaches the horizon in such a way that infnitely large stresses develop on the throat.

Correlation effects on non-Hermitian point-gap topology in zero dimension: reduction of topological classification

description: We analyze a zero-dimensional correlated system with special emphasis on the non-Hermitian point-gap topology protected by chiral symmetry. Our analysis elucidates that correlations destroy an exceptional point on a topological transition point which separates two topological phases in the non-interacting case; one of them is characterized by the zero-th Chern number $N_{0\mathrm{Ch}}=0$, and the other is characterized by $N_{0\mathrm{Ch}}=2$. This fact implies that correlations allow to continuously connect the two distinct topological phases in the non-interacting case without closing the point-gap, which is analogous to the reduction of topological classifications by correlations in Hermitian systems. Furthermore, we also discover a Mott exceptional point, an exceptional point where only spin degrees of freedom are involved.

Addition-transfer reactions of zirconium alkyne complexes
Creators: name: Mylvaganam, Murugesapillai
Publisher: name: University of British Columbia
Year: 2010

description: A unique type of reaction, namely the addition-transfer process, has been developed. This reaction transforms the zirconium alkyne complexes, Cp2Zr(η²-alkyne)(PMe₃), to 2-diphenylphosphino and 2-trimethylstannyl alkenyl zirconium compounds by reaction with Ph₂PCI and Me₃SnCl respectively. In the former process, the Ph₂P group is found to be cis to the Cp₂ZrCl group whereas, in the latter case, the Me₃Sn and the Cp₂ZrCl moieties are trans to one another. This reaction was also used to synthesize dienyl zirconium compounds having Ph₂P substitutions on the diene. Preliminary mechanistic proposals suggest that the Ph₂PCI is reacting via a four-centre pathway involving the P-Cl bond and one of the Zr-C bonds of the zirconium alkyne complex; whereas Me₃SnCl reacts via a transition state similar to a π-complex.

description: Single-species reaction-diffusion equations, such as the Fisher-KPP and Porous-Fisher equations, support travelling wave solutions that are often interpreted as simple mathematical models of biological invasion. Such travelling wave solutions are thought to play a role in various applications including development, wound healing and malignant invasion. One criticism of these single-species equations is that they do not explicitly describe interactions between the invading population and the surrounding environment. In this work we study a reaction-diffusion equation that describes malignant invasion which has been used to interpret experimental measurements describing the invasion of malignant melanoma cells into surrounding human skin tissues. This model explicitly describes how the population of cancer cells degrade the surrounding tissues, thereby creating free space into which the cancer cells migrate and proliferate to form an invasion wave of malignant tissue that is coupled to a retreating wave of skin tissue. We analyse travelling wave solutions of this model using a combination of numerical simulation, phase plane analysis and perturbation techniques. Our analysis shows that the travelling wave solutions involve a range of very interesting properties that resemble certain well-established features of both the Fisher-KPP and Porous-Fisher equations, as well as a range of novel properties that can be thought of as extensions of these well-studied single-species equations. Of particular interest is that travelling wave solutions of the invasion model are very well approximated by trajectories in the Fisher-KPP phase plane that are normally disregarded. This observation establishes a previously unnoticed link between coupled multi-species reaction diffusion models of invasion and a different class of models of invasion that involve moving boundary problems.

The microwave spectra of cyclopropyl bromide
Creators: name: Li, Hao
Publisher: name: University of British Columbia
Year: 2010

description: The microwave spectra of cyclopropyl bromide, C₃H₅Br, in its ground state, has been observed and analyzed in the frequency range 15-90 GHz. The spectra of two species were measured: C₃H₅⁷⁹Br and C₃H₅⁸¹Br. They contain strong a-type transitions and very weak c-type transitions which could not initially be assigned; all show Br quadrupole hyperfine structure with several large perturbations. A procedure specially developed for analysis of such spectra, which uses perturbations in the Br structure, was used to evaluate all the rotational constants accurately, as well as the Br quadrupole tensor, entirely from a-type R branch transitions. This has allowed some c-type transitions to be assigned. The principal values of the Br quadrupole tensor have been evaluated and have provided some information about the type of bonding involved in the C-Br bond.The centrifugal distortion constants have also been obtained.
Canine Demodecosis

Publisher: name: veterinary today

description: Demodex spp. mites are normally present as commensals in hair follicles and sebaceous glands in animals and humans, which multiply to excessive numbers causing clinical conditions. They have an elongated body with four stumpy legs, can be visualised under a microscope. Three species of demodectic mites are associated with disease in dogs. It is not contagious and is acquired from the dam during nursing. The most common species frequently encountered in dogs, Demodex canis, was first identified in 1859. Another causative agent is Demodex injai which has a longer body while D cornei has a short-body form, most likely to be a morphological variant of D canis (Mueller et al. 2020). There are various immunological, genetic, endocrine and other factors like breed, nutrition, length of hair, oxidative stress, debilitating diseases, that are risk factors and predisposing factors leading to rise in populations of mites associated with skin lesions like demodecosis. Various conditions like neoplasia, chemotherapy, hyperadrenocorticism or hyperthyroidism may lead to immunosuppression, triggering mite proliferation (Shchelkanov et al.,2020). The clinical presentation of demodecosis shows wide variation depending on the age at onset, the extent and severity of the lesions and the presence of secondary infection.

description: We analyse star formation in the nuclei of 9 Seyfert galaxies at spatial resolutions down to 0.085arcsec, corresponding to length scales of less than 10pc in some objects. Our data were taken mostly with the near infrared adaptive optics integral field spectrograph SINFONI. The stellar light profiles typically have size scales of a few tens of parsecs. In two cases there is unambiguous kinematic evidence for stellar disks on these scales. In the nuclear regions there appear to have been recent - but no longer active - starbursts in the last 10-300Myr. The stellar luminosity is less than a few percent of the AGN in the central 10pc, whereas on kiloparsec scales the luminosities are comparable. The surface stellar luminosity density follows a similar trend in all the objects, increasing steadily at smaller radii up to 10^{13}L_sun/kpc^2 in the central few parsecs, where the mass surface density exceeds 10^4M_sun/pc^2. The intense starbursts were probably Eddington limited and hence inevitably short-lived, implying that the starbursts occur in multiple short bursts. The data hint at a delay of 50--100Myr between the onset of star formation and subsequent fuelling of the black hole. We discuss whether this may be a consequence of the role that stellar ejecta could play in fuelling the black hole. While a significant mass is ejected by OB winds and supernovae, their high velocity means that very little of it can be accreted. On the other hand winds from AGB stars ultimately dominate the total mass loss, and they can also be accreted very efficiently because of their slow speeds.

description: Data from the DRIFT-IIa directional dark matter experiment are presented, collected during a near continuous 6 month running period. A detailed calibration analysis comparing data from gamma-ray, x-ray and neutron sources to a GEANT4 Monte Carlo simulations reveals an efficiency for detection of neutron induced recoils of 94+/-2(stat.)+/-5(sys.)%. Software-based cuts, designed to remove non-nuclear recoil events, are shown to reject 60Co gamma-rays with a rejection factor of better than 8x10-6 for all energies above threshold. An unexpected event population has been discovered and is shown here to be due to the alpha-decay of 222Rn daughter nuclei that have attached to the central cathode. A limit on the flux of neutrons in the Boulby Underground Laboratory is derived from analysis of unshielded and shielded data.

description: The O(2) model in Euclidean space-time is the zero-gauge-coupling limit of the compact scalar quantum electrodynamics. We obtain a dual representation of it called the charge representation. We study the quantum phase transition in the charge representation with a truncation to ``spin $S$," where the quantum numbers have an absolute value less than or equal to $S$. The charge representation preserves the gapless-to-gapped phase transition even for the smallest spin truncation $S = 1$. The phase transition for $S = 1$ is an infinite-order Gaussian transition with the same critical exponents $δ$ and $η$ as the Berezinskii-Kosterlitz-Thouless (BKT) transition, while there are true BKT transitions for $S \ge 2$. The essential singularity in the correlation length for $S = 1$ is different from that for $S \ge 2$. The exponential convergence of the phase-transition point is studied in both Lagrangian and Hamiltonian formulations. We discuss the effects of replacing the truncated $\hat{U}^{\pm} = \exp(\pm i \hatθ)$ operators by the spin ladder operators $\hat{S}^{\pm}$ in the Hamiltonian. The marginal operators vanish at the Gaussian transition point for $S = 1$, which allows us to extract the $η$ exponent with high accuracy.

description: The observed variation of the total cross section for the dp -> 3He eta reaction near threshold means that the magnitude of the s--wave amplitude falls very rapidly with the eta centre--of--mass momentum. It is shown here that recent measurements of the momentum dependence of the angular distribution imply a strong variation also in the phase of this amplitude. Such a behaviour is that expected from a quasi--bound or virtual eta-3He state. The interpretation can be investigated further through measurements of the deuteron or proton analysing powers and/or spin--correlations.

Laser desorption ionization Fourier transform ion cyclotron resonance (L.D.I.-F.T.-I.C.R.) mass spectrometric studies of some underivatized bacterial oligosaccharides
Creators: name: Lam, Zamas
Publisher: name: University of British Columbia
Year: 2011

description: This thesis describes the novel application of laser desorption ionization Fourier transform ion cyclotron resonance (l.d.i.-F.t.-i.c.r.) mass spectrometry for determining the sequence of underivatized oligosaccharides. As a starting point, four model oligosaccharides obtained from bacteriophage degradation of the corresponding bacterial capsular polysaccharides were analyzed. The experiments progressed from a linear pentasaccharide (Klebsiella K44), to a linear pentasaccharide containing an acid-labile pyruvic acid (Klebsiella K3), to a linear tetrasaccharide containing an acetamido hexose and an acid-labile neuraminic acid (E. coli K9), and finally to a "3+1" branched tetrasaccharide containing an lactic acid ether and a base-labile O-acetate (Klebsiella 22). The glycosidic bond and significant ring cleavage fragmentations observed in the mass spectra could be used for the sequencing of all three linear oligosaccharides. Furthermore, these unusual ring-cleaved fragments also provided some tentative indication on the positions of linkage on several monosaccharide residues. The fragments derived from these model oligosaccharides were used to propose a logical interpretation of the l.d.i.-F.t.-i.c.r. mass spectra of commercially available polysaccharide reported by others. Polysaccharides that have similar primary and tertiary structures gave similar mass spectra. This may be rationalized by the fact that fragmentation occurred at the sample layer or the selvedge. Consequently, the mass spectra reflected the primary and tertiary structures of the polysaccharides in the solid state. Finally, this l.d.i.-F.t.-i.c.r. technique was employed to sequence an unknown oligosaccharide obtained by anhydrous hydrogen fluoride degradation of the bacterial capsular polysaccharide. It was concluded that the unknown sample is composed of two tetrasaccharides with the same carbohydrate components, but with one structure substituted with serine and the other with threonine. Furthermore, indirect evidence suggests that the amino acids are linked to the carboxylic acid group of the hexuronic acid. However, two possible structures could be proposed for these oligosaccharides. The experimental results showed that l.d.i.-F.t.-i.c.r. mass spectrometry is well suited for the analysis of underivatized oligosaccharides, where the abundant ring fragments observed, can be used for a tentative indication of positions of linkage information. Furthermore, the high resolution data can be used to confirm the presence of unusual sugars and substituents.
The Dawes Review 9: The role of cold gas stripping on the star formation quenching of satellite galaxies

description: One of the key open questions in extragalactic astronomy is what stops star formation in galaxies. While it is clear that the cold gas reservoir, which fuels the formation of new stars, must be affected first, how this happens and what are the dominant physical mechanisms involved is still a matter of debate. At least for satellite galaxies, it is generally accepted that internal processes alone cannot be responsible for fully quenching their star formation, but that environment should play an important, if not dominant, role. In nearby clusters, we see examples of cold gas being removed from the star-forming disks of galaxies moving through the intracluster medium, but whether active stripping is widespread and/or necessary to halt star formation in satellites, or quenching is just a consequence of the inability of these galaxies to replenish their cold gas reservoirs, remains unclear. In this work, we review the current status of environmental studies of cold gas in star-forming satellites in the local Universe from an observational perspective, focusing on the evidence for a physical link between cold gas stripping and quenching of the star formation. We find that stripping of cold gas is ubiquitous in satellite galaxies in both group and cluster environments. While hydrodynamical mechanisms such as ram pressure are important, the emerging picture across the full range of dark matter halos and stellar masses is a complex one, where different physical mechanisms may act simultaneously and cannot always be easily separated. Most importantly, we show that stripping does not always lead to full quenching, as only a fraction of the cold gas reservoir might be affected at the first pericentre passage. We argue that this is a key point to reconcile apparent tensions between statistical and detailed analyses of satellite galaxies...(abridged)

description: 3D porous scaffolds based on agarose and nanocrystalline apatite, two structural components that act as a temporary mineralized extracellular matrix, were prepared by the GELPOR3D method. This shaping technology allows the introduction of thermally-labile molecules within the scaffolds during the fabrication procedure. An angiogenic protein, Vascular Endothelial Growth Factor, and an antibiotic, cephalexin, loaded in mesoporous silica nanoparticles, were included to design multifunctional scaffolds for bone reconstruction. The dual release of both molecules showed a pro-angiogenic behaviour in chicken embryos grown ex ovo, while, at the same time providing an antibiotic local concentration capable of inhibiting Staphylococcus aureus bacterial growth. In this sense, different release patterns, monitored by UV-spectroscopy, could be tailored as a function of the cephalexin loading strategy. The scaffold surface was characterized by a high hydrophilicity, as determined by contact angle measurements, that facilitated the adhesion and proliferation of preosteoblastic cells.

Charge Order and Superconductivity as Competing Brothers in Cuprate High-$T_{\rm c}$ Superconductors

description: Studies on the interplay between the charge order and the $d$-wave superconductivity in the copper-oxide high $T_{\rm c}$ superconductors are reviewed with a special emphasis on the exploration based on the unconventional concept of the electron fractionalization and its consequences supported by solutions of high-accuracy quantum many-body solvers. Severe competitions between the superconducting states and the charge inhomogeneity including the charge/spin striped states revealed by the quantum many-body solvers are first addressed for the Hubbard models and then for the {\it ab initio} Hamiltonians of the cuprates derived without adjustable parameters to represent the low-energy physics of the cuprates. The charge inhomogeneity and superconductivity are born out of the same mother, namely, the carrier attraction arising from the strong Coulomb repulsion near the Mott insulator (Mottness) and accompanied electron fractionalization. The same mother makes the severe competition of the two brothers inevitable. The electron fractionalization has a remarkable consequences on the mechanism of the superconductivity. Recent explorations motivated by the concept of the fractionalization and their consequences on experimental observations in energy-momentum resolved spectroscopic measurements including the angle resolved photoemission spectroscopy (ARPES) and the resonant inelastic X-ray spectroscopy (RIXS) are overviewed, with future vision for the integrated spectroscopy to challenge the long-standing difficulties in the cuprates as well as in other strongly correlated matter in general.

description: The absolute-scale electronic energetics of liquid water and aqueous solutions, both in the bulk and at associated interfaces, are the central determiners of water-based chemistry. However, such information is generally experimentally inaccessible. We demonstrate that a refined implementation of the liquid microjet photoelectron spectroscopy (PES) technique can be adopted to address this. Implementing concepts from condensed matter physics, we establish novel all-liquid-phase vacuum and equilibrated solution-metal-electrode Fermi level referencing procedures. This enables the precise and accurate quantification of previously elusive solute-induced perturbations of water's electronic energetics and vertical ionization energy (VIE) definition on an absolute and universal chemical potential scale. Applying these procedures over a broad range of ionization energies, we accurately and respectively determine the VIE and oxidative stability of liquid water as 11.33 $\pm$ 0.02 eV and 6.60 $\pm$ 0.08 eV with respect to its liquid-vacuum-interface potential and Fermi level. Combining our referencing schemes, we determine the work function of liquid water as 4.73 $\pm$ 0.09 eV. Further, applying our novel approach to a pair of exemplary aqueous solutions, we extract absolute VIEs of aqueous iodide anions, reaffirm the robustness of water's electronic structure to high bulk salt concentrations, and quantify reference-level dependent reductions of water's VIE and a 0.48 $\pm$ 0.13 eV contraction of the solution's work function upon partial hydration of a known surfactant. Our combined experimental accomplishments mark a major advance in our ability to quantify electronic-structure interactions and chemical reactivity in water, which now explicitly extends to the measurement of absolute-scale bulk and interfacial solution energetics, including those of relevance to aqueous electrochemical processes.

description: Neural network quantum states (NQS) have been widely applied to spin-1/2 systems where they have proven to be highly effective. The application to systems with larger on-site dimension, such as spin-1 or bosonic systems, has been explored less and predominantly using spin-1/2 Restricted Boltzmann Machines (RBMs) with a one-hot/unary encoding. Here we propose a more direct generalisation of RBMs for spin-1 that retains the key properties of the standard spin-1/2 RBM, specifically trivial product states representations, labelling freedom for the visible variables and gauge equivalence to the tensor network formulation. To test this new approach we present variational Monte Carlo (VMC) calculations for the spin-1 antiferromagnetic Heisenberg (AFH) model and benchmark it against the one-hot/unary encoded RBM demonstrating that it achieves the same accuracy with substantially fewer variational parameters. Further to this we investigate how the hidden unit complexity of NQS depend on the local single-spin basis used. Exploiting the tensor network version of our RBM we construct an analytic NQS representation of the Affleck-Kennedy-Lieb-Tasaki (AKLT) state in the $xyz$ spin-1 basis using only $M = 2N$ hidden units, compared to $M \sim O(N^2)$ required in the $S^z$ basis. Additional VMC calculations provide strong evidence that the AKLT state in fact possesses an exact compact NQS representation in the $xyz$ basis with only $M=N$ hidden units. These insights help to further unravel how to most effectively adapt the NQS framework for more complex quantum systems.

description: Active regions often show S-shaped structures in the corona called sigmoids. These are highly sheared and twisted loops formed along the polarity inversion line. They are considered to be one of the best pre-eruption signatures for CMEs. Here, we investigate the thermodynamic evolution of an on-disk sigmoid observed during December 24-28, 2015. For this purpose, we have employed Emission Measure (EM) and filter-ratio techniques on the observations recorded by the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) and X-ray Telescope (XRT) onboard Hinode. The EM analysis showed multi-thermal plasma along the sigmoid and provided a peak temperature of 10-12.5 MK for all observed flares. The sigmoidal structure showed emission from Fe XVIII (93.93 Å) and Fe XXI 128.75 Å) lines in the AIA 94 and 131 Å channels, respectively. Our results show that the hot plasma is often confined to very hot strands. The temperature obtained from the EM analysis was found to be in good agreement with that obtained using the XRT, AIA, and GOES filter-ratio methods. These results provide important constraints for the thermodynamic modeling of sigmoidal structures in the core of active regions. Moreover, this study also benchmarks different techniques available for temperature estimation in solar coronal structures.

description: The spin vortices are shown to be created through the Kibble-Zurek (KZ) mechanism in a quantum phase transition of a spin-1 ferromagnetic Bose-Einstein condensate, when the applied magnetic field is quenched below a critical value. It is shown that the magnetic correlation functions have finite correlation lengths, and magnetizations at widely separated positions grow in random directions, resulting in spin vortices. We numerically confirm the scaling law that the winding number of spin vortices is proportional to the square root of the length of the closed path, and for slow quench, proportional to $τ_{\rm Q}^{-1/6}$ with $τ_{\rm Q}$ being the quench time. The relation between the spin conservation and the KZ mechanism is discussed.

description: In April 2024, Members of the European Parliament (MEPs) approved the creation of the European Health Data Space (EHDS). The EHDS aims to improve citizens’ access to and control over their electronic health data for primary (healthcare) and secondary (clinical research) uses. Anticipating the endorsement of the EHDS Regula􀆟on, c4c held a workshop in February 2024 to explore the potential impact of this legislation on paediatric clinical trials. The workshop highlighted that the unique challenges of paediatric data had not been formally considered in the design of the EHDS, particularly when it comes to the provisions in it for the primary use of health data.

This paper highlights the collaborations and resources developed and fostered by c4c that aim to address the gaps in paediatric data standards and increase awareness of the need for interoperability. These standards also have a role to improve the care of children as they transition into adulthood as they provide standardized data that can support continuity of care. The collaborations and resources developed over the life of the c4c project will now also play an important role in pushing the paediatric agenda within the EHDS to ensure it does not miss a vital opportunity to accelerate paediatric research and, by extension, rare disease research.

description: Dans le cadre de ce mémoire, nous avons porté notre attention sur les effets d’une intervention métacognitive auprès des élèves d’une classe de l’enseignement spécialisé en institution. Dans la littérature, peu d’études se sont intéressées à une telle intervention dans le cadre d’une classe hétérogène. Les études recensées portent souvent sur des cas uniques ou sur des élèves de l’école ordinaire. La particularité de notre étude est de proposer une intervention métacognitive par les jeux afin d’apprendre des stratégies cognitives et des habiletés métacognitives en travaillant avec l’ensemble d’une classe. Les objectifs de notre recherche-action sont d’étudier si, à la suite d’ une intervention métacognitive par le jeu, les élèves sont capables d’appliquer ces stratégies et habiletés apprises sur des tâches scolaires proches et éloignées. Notre classe est composée de sept élèves ayant une déficience intellectuelle légère, des troubles du spectre de l’autisme, des troubles du comportement ou un déficit de l’attention. L’intervention métacognitive porte sur douze séances hebdomadaires d’une durée de 4 heures. Dans un premier temps, les élèves apprennent les stratégies cognitives et les habiletés métacognitives par les jeux. Elles sont ensuite transférées sur du matériel scolaire. Durant la semaine, l’enseignante titulaire continue de travailler autour de ces stratégies et habiletés. Les données récoltées portaient sur des tâches effectuées au pré-test et au post-test, ainsi que sur nos notes d’observation et mémo récoltés au fur et à mesure des semaines. Les résultats montrent que certain·e·s élèves ont pu profiter de l’intervention métacognitive pour utiliser davantage des stratégies cognitives et habiletés métacognitives. D’autres sont encore dans la phase d’acquisition et ont encore besoin de guidance de l’enseignante pour pouvoir les appliquer. De manière générale, nous pouvons conclure que cette recherche a permis de souligner la complexité de proposer une intervention métacognitive à un groupe d’élèves hétérogène.
