description: In a previous paper Crater and Van Alstine applied the Two Body Dirac equations of constraint dynamics to the meson quark-antiquark bound states using a relativistic extention of the Adler-Piran potential and compared their spectral results to those from other approaches, ones which also considered meson spectroscopy as a whole and not in parts. In this paper we explore in more detail the differences and similarities in an important subset of those approaches, the quasipotential approach. In the earlier paper, the transformation properties of the quark-antiquark potentials were limited to a scalar and an electromagnetic-like four vector, with the former accounting for the confining aspects of the overall potential, and the latter the short range portion. A part of that work consisted of developing a way in which the static Adler-Piran potential was apportioned between those two different types of potentials in addition to covariantization. Here we make a change in this apportionment that leads to a substantial improvement in the resultant spectroscopy by including a time-like confining vector potential over and above the scalar confining one and the electromagnetic-like vector potential. Our fit includes 19 more mesons than the earlier results and we modify the scalar portion of the potential in such a way that allows this formalism to account for the isoscalar mesons η and η' not included in the previous work. Continuing the comparisons made in the previous paper with other approaches to meson spectroscopy we examine in this paper the quasipotential approach of Ebert, Faustov, and Galkin for a comparison with our formalism and spectral results.

Intake-based weaning of dairy calves and the influence of forage type
Creators: name: Welk, Allison
Publisher: name: University of British Columbia
Year: 2022

description: The objective of this study was to assess the effects of intake-based weaning methods and forage type on behaviour and growth of dairy calves. Holstein calves (n = 108) were randomly assigned to 1 of 3 weaning treatments: milk reduction by age (wean-by-age), individual dry matter intake (DMI) (wean-by-intake), or combination of individual DMI and age (wean-by-combination). Groups of calves were alternately assigned to 1 of 2 forage treatments: grass hay (Hay), or silage-based total mixed ration (TMR) (n = 6 groups per treatment). Until d 30, all calves received 12 L/d of milk. On d 31, milk was reduced by 25% of the individual’s average milk intake. For wean-by-age calves (n = 31), milk remained stable until d 62 when milk was reduced until weaning at d 70. For wean-by-intake calves (n = 35), milk was further reduced by 25% once calves consumed 200, 600, and 1150 g DM/d of solid feed. For wean-by-combination calves (n = 35), milk remained stable until calves consumed 200 g DM/d; milk was then reduced until weaning at d 70. If calves failed to reach DMI targets by d 62 (failed-to-wean, n = 10), milk was reduced until weaning at d 70. 27 wean-by-intake calves met all 3 DMI targets (successful-intake) and 33 wean-by-combination calves met the 1 DMI target (successful-combination). Successful-intake and successful-combination calves had greater body weight (BW) at 84 d than wean-by-age calves, followed by failed-to-wean calves (123.0 vs 121.6 vs 117.0 vs 100.1 ± 3.1 kg, respectively). During weaning, successful-intake calves ate more starter than successful-combination, wean-by-age, and failed-to-wean calves (1.18 vs 0.85 vs 0.49 vs 0.14 ± 0.08 kg DM/d, respectively). Hay calves had greater BW at 84 d than TMR calves (124.0 vs 119.0 ± 1.6 kg, respectively). During weaning, Hay calves consumed more starter than TMR calves (0.85 vs 0.65 ± 0.09 kg DM/d, respectively). Intake-based weaning can improve performance of calves that successfully wean, and grass hay can improve starter intake and growth around weaning. Some calves consume little solid feed before weaning; further research is needed to understand how these calves should be managed.

description: Online reading is becoming more and more popular in learning and teaching environments. However, little is known about characteristics of hypertexts that influence on reading comprehension and attention. Some previous studies have suggested that attention failures also referred to as mind wandering (MW) occur whenever the available resources of the reader (e.g., working memory capacity; WMC) do not match the task demands (e.g., text difficulty). This study aims to investigate the effect of restructuring a linear text into different hypertext types by means of hyperlinks on MW in a cognitively demanding task like reading. We hypothesized that participants exposed to a difficult to read hypertext with networked structure engage more in task-unrelated thoughts (TUTs) compared to participants asked to read a difficult but hierarchically organized hypertext. 90 participants read either an easy or difficult version of the same unfamiliar hypertext with either a hierarchical or networked structure and with embedded thought probes. Reading comprehension and WMC measures followed. As expected, participants reading the difficult (to read) hypertext with networked link structure showed significantly more TUTs than participants reading the hierarchical link structure hypertext. In addition, readers with a low-WMC showed significantly more TUTs while reading a demanding hypertext regardless of its structure. These findings are in line with the view that mind wandering occurs if available resources do not match with task demands, and thus deepen assumptions about hyperlinks as new cohesive devices.

description: Considering the results from Hořava-Lifshitz (HL) theory, a more precise relation between the number of bits and area in the holographic system is proposed. With this corrected relation and Debye model, two modified Friedmann equations are derived from the Hawking temperature and the Unruh temperature separately in entropic force. These equations could be better in describing the whole evolution of the universe.

title: Measuring marine currents using underwater acoustics
Creators: name: Smith, Tim A.
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The speed of sound in water rises and falls with temperature, current speed, salinity, and pressure. Precisely measured underwater acoustic travel times can be used to calculate these parameters for a body of water. If the salinity and pressure along the acoustic path is known, a system of two underwater hydrophones transmitting bi-directionally can indirectly measure both temperature and water velocity. Summing the bi-directional travel times isolates the temperature component, while subtracting the travel times isolates the component of current speed.
 There has been much work in using this method for current point detectors as well as networks covering very large distances (> 100km). The feasibility of using acoustic travel times for measurements in the 100m - 3km range has been less explored. Accurate measurements at this range may be valuable in iceberg tracking for the offshore oil and gas industry, as well as in building high resolution maps for environmental studies. This range presents some new challenges, as a distributed network must remain highly synchronized to obtain sufficiently accurate travel times. Multipath travel is also highly problematic in this range.
 A system has been developed and used to measure tidal currents in the North Atlantic Ocean. The design was built from the ground up. The hardware, software, and data processing are built to work with non-specialized low-cost equipment in a variety of harsh marine deployment conditions. Field testing showed that the system was capable of measuring currents to within ±4cm/s across a 130m range. Quantitative error analysis is included which shows that much higher accuracies could be achieved at the 1km range.

description: We give a unified overview of the zero temperature phases of compressible quantum matter: i.e. phases in which the expectation value of a globally conserved U(1) density, Q, varies smoothly as a function of parameters. Provided the global U(1) and translational symmetries are unbroken, such phases are expected to have Fermi surfaces, and the Luttinger theorem relates the volumes enclosed by these Fermi surfaces to . We survey models of interacting bosons and/or fermions and/or gauge fields which realize such phases. Some phases have Fermi surfaces with the singularities of Landau's Fermi liquid theory, while other Fermi surfaces have non-Fermi liquid singularities. Compressible phases found in models applicable to condensed matter systems are argued to also be present in models obtained by applying chemical potentials (and other deformations allowed by the residual symmetry at non-zero chemical potential) to the paradigmic supersymmetric gauge theories underlying gauge-gravity duality: the ABJM model in spatial dimension d=2, and the N=4 SYM theory in d=3.

description: Numerical simulation of quantum systems is crucial to further our understanding of natural phenomena. Many systems of key interest and importance, in areas such as superconducting materials and quantum chemistry, are thought to be described by models which we cannot solve with sufficient accuracy, neither analytically nor numerically with classical computers. Using a quantum computer to simulate such quantum systems has been viewed as a key application of quantum computation from the very beginning of the field in the 1980s. Moreover, useful results beyond the reach of classical computation are expected to be accessible with fewer than a hundred qubits, making quantum simulation potentially one of the earliest practical applications of quantum computers. In this paper we survey the theoretical and experimental development of quantum simulation using quantum computers, from the first ideas to the intense research efforts currently underway.

description: It is generally accepted that doped Mott insulators can be well characterized by the t-J model. In the t-J model, the electron fractionalization is dictated by the phase string effect. We found that in the underdoped regime, the antiferromagnetic and superconducting phases are dual: in the former, holons are confined while spinons are deconfined, and {\it vice versa} in the latter. These two phases are separated by a novel phase, the so-called Bose-insulating phase, where both holons and spinons are deconfined. A pair of Wilson loops was found to constitute a complete set of order parameters determining this zero-temperature phase diagram. The quantum phase transitions between these phases are suggested to be of non-Landau-Ginzburg-Wilson type.

Cellular origin influences the immune microenvironment in a pancreatic cancer mouse model with loss of Pten and activation of KRAS
Creators: name: Dou, Yan
Publisher: name: University of British Columbia
Year: 2022

description: Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with an overall 5-year survival rate of merely 10%. Mouse studies in the past decade have made progress towards a better understanding of how PDAC cellular origin affects tumorigenesis. However, there is little study done on the immune microenvironment differences between acinar and ductal cell-derived precursor lesions and PDAC. Following our previous study that showed loss of Pten with oncogenic KrasG12D mutations in the ductal cells (KPtenΔDuct/+) resulted the formation of intraductal papillary mucinous neoplasias (IPMN) as the precursor lesion in mice, we further found similar mutations in the acinar cells (KPtenΔAcinar/+) formed pancreatic intraepithelial neoplasia (PanIN) instead. I subsequently used the KPtenΔDuct/+and KPtenΔAcinar/+ models to elucidate the effect of cellular origin on the immune microenvironment by performing immunohistochemistry. I focused on immune cell infiltration densities in precursor lesions and PDAC derived from KPtenΔDuct/+ and KPtenΔAcinar/+ mice and found that immune cell population and its changes throughout tumorigenesis are different starting at a precursor lesion stage between these two models. Additionally, macrophages polarized by conditioned media derived from KPtenΔDuct PDAC cells were polarized in less magnitude compared with macrophages polarized by KPtenΔAcinar PDAC cells. This difference in polarization was at least partially due to the lower expression of GM-CSF in KPtenΔDuct PDAC cells. Our study is the first to directly compare immune cell population between acinar- and ductal-derived PDAC with the same genetic background. Our study suggests cellular origin could influence PDAC immune heterogeneity.

description: The nearby star GJ 1214 hosts a planet intermediate in radius and mass between Earth and Neptune, resulting in some uncertainty as to its nature. We have observed this planet, GJ 1214b, during transit with the high-resolution, near-infrared NIRSPEC spectrograph on the Keck II telescope, in order to characterize the planet's atmosphere. By cross-correlating the spectral changes through transit with a suite of theoretical atmosphere models, we search for variations associated with absorption in the planet atmosphere. Our observations are sufficient to rule out tested model atmospheres with wavelength-dependent transit depth variations >5e-4 over the wavelength range 2.1 - 2.4 micron. Our sensitivity is limited by variable slit loss and telluric transmission effects. We find no positive signatures but successfully rule out a number of plausible atmospheric models, including the default assumption of a gaseous, H-dominated atmosphere in chemical equilibrium. Such an atmosphere can be made consistent if the absorption due to methane is reduced. Clouds can also render such an atmosphere consistent with our observations, but only if they lie higher in the atmosphere than indicated by recent optical and infrared measurements. When taken in concert with constraints from other groups, our results support a consensus model in which the atmosphere of GJ 1214b contains significant H and He, but where methane is depleted. If this depletion is the result of photochemical processes, it may also produce a haze that suppresses spectral features in the optical.

description: Flowering plants with indeterminate inflorescences often produce more floral structures than they require. We found that floral primordia initiations in barley (Hordeum vulgare L.) are molecularly decoupled from their maturation into grains. While initiation is dominated by flowering-time genes, floral growth is specified by light signaling, chloroplast, and vascular developmental programs orchestrated by barley CCT MOTIF FAMILY 4 (HvCMF4), which is expressed in the inflorescence vasculature. Consequently, mutations in HvCMF4 increase primordia death and pollination failure, mainly through reducing rachis greening and limiting plastidial energy supply to developing heterotrophic floral tissues. We propose that HvCMF4 is a sensory factor for light that acts in connection with the vascular-localized circadian clock to coordinate floral initiation and survival. Notably, stacking beneficial alleles for both primordia number and survival provides positive implications on grain production. Our findings provide insights into the molecular underpinnings of grain number determination in cereal crops.

description: Background: In node-negative breast cancer (NNBC), a high risk of recurrence is determined by clinico-pathological or tumor-biological assessment. Taxanes may improve adjuvant chemotherapy. Methods: NNBC 3-Europe, the first randomized phase-3 trial in node-negative breast cancer (BC) with tumor-biological risk assessment, recruited 4146 node-negative breast cancer patients from 2002 to 2009 in 153 centers. Risk assessment was performed by clinico-pathological factors (43%) or biomarkers (uPA/PAI-1, urokinase-type plasminogen activator/its inhibitor PAI-1). High-risk patients received six courses 5-fluorouracil (500 mg/m2), epirubicin (100 mg/m2), cyclophosphamide (500 mg/m2) (FEC), or three courses FEC followed by three courses docetaxel 100 mg/m2 (FEC-Doc). Primary endpoint was disease-free survival (DFS). Results: In the intent-to-treat population, 1286 patients had received FEC-Doc, and 1255 received FEC. Median follow-up was 45 months. Tumor characteristics were equally distributed; 90.6% of tested tumors had high uPA/PAI-1-concentrations. Planned courses were given in 84.4% (FEC-Doc) and 91.5% (FEC). Five-year-DFS was 93.2% (95% C.I. 91.1–94.8) with FEC-Doc and 93.7% (91.7–95.3) with FEC. Five-year-overall survival was 97.0% (95.4–98.0) for FEC-Doc and 96.6% % (94.9–97.8) for FEC. Conclusions: With adequate adjuvant chemotherapy, even high-risk node-negative breast cancer patients have an excellent prognosis. Docetaxel did not further reduce the rate of early recurrences and led to significantly more treatment discontinuations.

description: Hausdorff relation, topologically identifying points in a given space, belongs to elementary tools of modern mathematics. We show that if subtle enough mathematical methods are used to analyze this relation, the conclusions may be far-reaching and illuminating. Examples of situations in which the Hausdorff relation is of the total type, i.e., when it identifies all points of the considered space, are the space of Penrose tilings and space-times of some cosmological models with strong curvature singularities. With every Hausdorff relation a groupoid can be associated, and a convolutive algebra defined on it allows one to analyze the space that otherwise would remain intractable. The regular representation of this algebra in a bundle of Hilbert spaces leads to a von Neumann algebra of random operators. In this way, a probabilistic description (in a generalized sense) naturally takes over when the concept of point looses its meaning. In this situation counterparts of the position and momentum operators can be defined, and they satisfy a commutation relation which, in the suitable limiting case, reproduces the Heisenberg indeterminacy relation. It should be emphasized that this is neither an additional assumption nor an effect of a quantization process, but simply the consequence of a purely geometric analysis.

description: The transformation of functional proteins into amyloidic plaques is responsible for the impairment of neurological functions in patients fallen victim to debilitating neurological conditions like Alzheimer's, Parkinson's, and Huntington's diseases. The nucleating role of amyloid beta (Aβ1-40) peptide into amyloids is well established. Herein, lipid hybrid-vesicles are generated with glycerol/cholesterol-bearing polymers aiming to alter the nucleation process and modulate the early phases of Aβ1-40 fibrillation. Hybrid-vesicles (±100 nm) are prepared by incorporating variable amounts of cholesterol-/glycerol-conjugated poly(di(ethylene glycol)macrylates)n polymers into 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) membranes. The in vitro fibrillation kinetics coupled to transmission electron microscopy (TEM) is employed to investigate the role of hybrid-vesicles on Aβ1-40 fibrillation without destroying the vesicular membrane. Both polymers, when embedded in hybrid-vesicles (up to 20%) significantly prolonged the fibrillation lag phase (tlag) compared to a small acceleration in the presence of DOPC vesicles, irrespective of the amount of polymers inside the hybrid-vesicles. Along with this notable retardation effect, a morphological transformation of the amyloid's secondary structures to amorphous aggregates or the absence of fibrillar structures when interacting with the hybrid-vesicles is confirmed by TEM and circular dichroism (CD) spectroscopy.

description: We propose a two-path vortex interferometry experiment based on the Aharonov-Casher effect for detecting the non-Abelian nature of vortices in a chiral p-wave superconductor. The effect is based on observing vortex interference patterns upon enclosing a finite charge of externally controllable magnitude within the interference path. We predict that when the interfering vortices enclose an odd number of identical vortices in their path, the interference pattern disappears only for non-Abelian vortices. When pairing involves two distinct spin species, we derive the mutual statistics between half quantum and full quantum vortices and show that, remarkably, our predictions still hold for the situation of a full quantum vortex enclosing a half quantum vortex in its path. We discuss the experimentally relevant conditions under which these effects can be observed.

description: We study the differences and similarities in the luminosities of bound, infalling and the so-called backsplash (Gill et al. 2005) galaxies of the Milky Way and M31 using a hydrodynamical simulation performed within the Constrained Local UniversE Simulation (CLUES) project. The simulation models the formation of the Local Group within a self-consistent cosmological framework. We find that even though backsplash galaxies passed through the virial radius of their host halo and hence may have lost a (significant) fraction of their mass, their stellar populations are hardly affected. This leaves us with comparable luminosity functions for infalling and backsplash galaxies and hence little hope to decipher their past (and different) formation and evolutionary histories by luminosity measurements alone. Nevertheless, due to the tidal stripping of dark matter we find that the mass-to-light ratios have changed when comparing the various populations against each other: they are highest for the infalling galaxies and lowest for the bound satellites with the backsplash galaxies in-between.

description: The invasive herb Lupinus polyphyllus has been focus of a number of fact sheets worldwide but a comprehensive summary of the species’ taxonomy and morphology, distribution, habitat requirements, and biology has been lacking. This paper gives a thorough account of the species’ systematic position and taxonomy, highlighting the difficulties to delimit taxa, which is related to interbreeding among members of this genus. However, L. polyphyllus var. polyphyllus is apparently the taxon that has naturalized and is regionally invasive in temperate-humid climates worldwide. We also present an updated distribution map of L. polyphyllus in the native and invaded ranges, which highlights seven regions in the world where the species has been established. We show that the climatic niche of L. polyphyllus in the invaded range shifts towards higher summer precipitation and lower isothermality, probably because the invaded range includes subcontinental regions of eastern Europe and western Siberia. The habitats of L. polyphyllus range from rather dry to wet, have moderately acidic to strongly acidic soils, and the species’ indicator values across Europe suggest that it occurs along a gradient from very nutrient poor sites to intermediate to rich sites from northern to southern Europe. The species shows high resistance to both drought and frost. In Central Europe, the species has a stronghold in alpic mountain hay meadows, abandoned meadows and pastures, low and medium altitude hay meadows, anthropogenic herb stands and temperate thickets and scrubs. In northern Europe, the species occurs in anthropogenic herb stands along roads and railroads as well as in abandoned pastures and fields. We also found some doubtful information about L. polyphyllus in the literature. This refers to its description as “rhizomatous perennial” although it lacks rhizomes; an apparently very high longevity of its seeds, which may only be true under artificial conditions in an ex situ seed repository; and a very deep rooting depth, which may not represent the average rooting depth but rather an extreme value. Knowledge about the interrelationships between the species’ future population dynamics and spread and ongoing climate warming is lacking. Finally, our review points out that there is currently no evidence-based strategy for a cost-efficient management of L. polyphyllus although it is among the most problematic non-native plant species in Europe due to its environmental and socio-economic impacts.

Memes, street art, and Hong Kong : the aesthetics of a political movement in new media arts
Creators: name: Wu, Xinran
Publisher: name: University of British Columbia
Year: 2022

description: This thesis explores the visual materials produced during the 2019 Anti-Extradition Law Amendment Bill Movement in Hong Kong. Focusing on protest ephemera, this thesis examines first the use of internet-based memes, then street art as an extension of the online world, and finally 3D printing technology as a synthesis of these to understand the roll new media played and continues to play in shaping political movements in the contemporary age. I contend that the visual cultures of protest produced in Hong Kong represent an exciting new hybridization of online/offline worlds and art forms. 3D-printed materials are functionally code but can take physical form. Political life has always straddled the public and private, but with the advent and development of contemporary internet cultures, it has also entered our social lives, blurring these boundaries even further. These works are at once situated and placeless, universal and deeply enigmatic, intangible and physical. These contradictions and juxtapositions are what makes the works compelling. Through this exploration in the aesthetic productions in Hong Kong’s 2019 Pro-Democracy Movement, I see a future in understanding how and where internet cultures and life will continue to permeate the physical world. The three examples discussed in this thesis represent models of communal healing and remembrance, and I hope that we might see street art return to Hong Kong when a post COVID-19 era finally arrives. For now, the city’s young continue to share memes and other images online, their humour and politics creating a community for themselves with a pictorial language only they know.

description: Gaudin subalgebras are abelian Lie subalgebras of maximal dimension spanned by generators of the Kohno-Drinfeld Lie algebra t_n. We show that Gaudin subalgebras form a variety isomorphic to the moduli space of stable curves of genus zero with n+1 marked points. In particular, this gives an embedding of the moduli space in a Grassmannian of (n-1)-planes in an n(n-1)/2-dimensional space. We show that the sheaf of Gaudin subalgebras over the moduli space is isomorphic to a sheaf of twisted first order differential operators. For each representation of the Kohno--Drinfeld Lie algebra with fixed central character, we obtain a sheaf of commutative algebras whose spectrum is a coisotropic subscheme of a twisted version of the logarithmic cotangent bundle of the moduli space.

description: We present a detailed study of the heating effects in dielectric measurements carried out on a liquid. Such effects come from the dissipation of the electric power in the liquid and give a contribution to the nonlinear third harmonics susceptibility chi_3 which depends on the frequency and temperature. This study is used to evaluate a possible `spurious' contribution to the recently measured nonlinear susceptibility of an archetypical glassforming liquid (Glycerol). Those measurements have been shown to give a direct evaluation of the number of dynamically correlated molecules temperature dependence close to the glass transition temperature T_g~190K (Crauste-Thibierge et al., Phys. Rev. Lett 104,165703(2010)). We show that the heating contribution is totally negligible (i) below 204K at any frequency; (ii) for any temperature at the frequency where the third harmonics response chi_3 is maximum. Besides, this heating contribution does not scale as a function of f/f_α, with f_α(T) the relaxation frequency of the liquid. In the high frequency range, when f/f_α >= 1, we find that the heating contribution is damped because the dipoles cannot follow instantaneously the temperature modulation due to the heating phenomenon. An estimate of the magnitude of this damping is given.

description: This study presents the results of the development of semi-transparent Cu(In,Ga)Se2 (CIGSe) mini-modules for the application in building integrated photovoltaics (BIPV). Applying in-situ X-ray diffraction in real-time during CIGSe growth we find that the bulk of indium-tin-oxide (ITO), acting as the transparent back contact, is chemically stable in CIGSe processing. CIGSe layers grown on reactively sputtered ITO (Ar/O2 flux ratio = 60:1) or on ITO annealed in ambient air have a proportionally higher (220/204) orientation compared to CIGSe layers grown on as fabricated ITO sputtered solely by Ar. However, independent from the fabrication and annealing state of the ITO back contact, after CIGSe deposition at high substrate temperatures ≥600 °C accumulation of Ga at the CIGSe/ITO back contact interface combined with reduced solar cell efficiency is observed. This Ga accumulation visible in elemental depth profiles is attributed to the formation of gallium-oxide (GaOx). Applying a very thin (≈10–30 nm) functional molybdenum layer in between CIGSe and the ITO back contact inhibits the formation of GaOx. Based on this Mo/ITO back contact configuration semi-transparent 10 × 10 cm2 mini-modules with 14 cells interconnected in series have been fabricated. Module parameters resulted in a fill factor of 63% and >12% in efficiency. The solar active coverage of the modules amounts to ≈70%, and the average visible transmittance (in the range 380–780 nm) of the transparent sections was 27.6% (9.6% for the total area of the device). Optimisation of the Mo/ITO contact allows increasing this transparency to values > 50%. Long-term outdoor testing of a semi-transparent module prototype reveals no degradation in electric output power for 3 months, demonstrating the device stability under changing climatic conditions.

description: This paper presents a conceptual study for the phenomenon of fire spread. The proposed study is based on simulations using the RoboCup Rescue environment. Using a socio-cognitive approach, it can be used in three dimensions: (i) assist in proposing new structures or alternatives to situations of collective panic, checking the viability of their existence and operation; (ii) obtain a better understanding of the reasons social, anthropological, psychological, etc. that subsidize and direct the type of collective behavior in crowd panic; (iii) assist in decision making aimed at minimizing the loss of life in a situation of spreadingfire. One of the challenges to be overcome in this research is the integration of the different theories andcomputational environments in order to open paths for future researches. Making possible a further studyon phenomenon of panic in crowds in danger situation.

description: Ubiquitination and deubiquitylation regulate essential cellular processes and involve hundreds of sequentially acting enzymes, many of which are barely understood. OTUD3 is an evolutionarily highly conserved deubiquitinase involved in many aspects of cellular homeostasis. However, its biochemical properties and physiological role during development are poorly understood. Here, we report on the expression of OTUD3 in human tissue samples where it appears prominently in those of neuronal origin. In cells, OTUD3 is present in the cytoplasm where it can bind to microtubules. Interestingly, we found that OTUD3 cleaves preferentially at K6 and K63, i.e., poly-ubiquitin linkages that are not primarily involved in protein degradation. We employed Xenopus embryos to study the consequences of suppressing otud3 function during early neural development. We found that Otud3 deficiency led to impaired formation of cranial and particularly of cranial neural crest-derived structures as well as movement defects. Thus, OTUD3 appears as a neuronally enriched deubiquitinase that is involved in the proper development of the neural system.

description: A stable diaqua-bis(N-benzoylanthranilato)-ethylato-copper(II) complex was synthesized by the reaction of N-benzoylanthranilic acid (N-baaH) and CuSO4·5H2O in 1:1 molar ratio in ethanol. Its crystals were structurally characterized by single crystal X-ray analysis. The complex has a distorted square planar CuO5 geometry. In the crystal, molecules are linked in inversion-related mode, forming dimers, which generate alternate 𝑅2 2(12) ring motifs in a linked chain that runs along (100) plane. These chains are stacking via van der Waals interactions forming a two-dimensional supramolecular network.
