description: We suggest to classify baryon resonances as single-quark states in a mean field, and/or as its collective excitations. Identifying the Roper resonance N(1440), the nucleon resonance N(1535), and the singlet hyperon Lambda(1405) as single-quark excitations, we find that there must be an exotic S=+1 baryon resonance Theta+ (the "pentaquark") with a mass about 1440+1535-1405=1570 MeV and spin-parity one-half-plus. We argue that Theta+ is an analog of the Gamov--Teller excitation long known in nuclear physics.

description: Introduction: The intracranial vascular anatomical variations, although rare, represent a interesting field of research, since many anomalous variants are possible and in most cases they remain asymptomatic. The capability of the cerebral circulation to adapt to several flow changes is confirmed by the fact that in several cases these anatomical variation compensate for an eventual unsuccessful development of the normal circulation, expecially in the posterior section of cerebral circulation.
 Materials and Methods: A comprehensive review of PubMed literature was performed and three clinical cases have been analyzed.
 Results: Several angiographic and MR-angiography reports have been evaluated, regarding general and specific anatomical variants of the posterior circulation.
 Discussion: Although rare, the anatomical variations of the posterior intracranial circulation represent an interesting field of investigation in order to achieve a better comprehension of the embryological development of the circulatory system.

description: The full set of equations governing the structure and the evolution of self--gravitating spherically symmetric dissipative fluids with anisotropic stresses, is written down in terms of five scalar quantities obtained from the orthogonal splitting of the Riemann tensor, in the context of general relativity. It is shown that these scalars are directly related to fundamental properties of the fluid distribution, such as: energy density, energy density inhomogeneity, local anisotropy of pressure, dissipative flux and the active gravitational mass. It is also shown that in the static case, all possible solutions to Einstein equations may be expressed explicitly through these scalars. Some solutions are exhibited to illustrate this point.

description: We employed the {\it VISTA near-infrared $YJK_\mathrm{s}$ survey of the Magellanic System} (VMC), to analyse the $Y,\,J,\,K_\mathrm{s}$ light curves of $δ$ Cepheid stars (DCEPs) in the Large Magellanic Cloud (LMC). Our sample consists of 4408 objects accounting for 97 per cent of the combined list of OGLE\,IV and {\it Gaia}\,DR2 DCEPs. We determined a variety of period-luminosity ($PL$) and period-Wesenheit $PW$ relationships for Fundamental (F) and First Overtone (1O) pulsators. We discovered for the first time a break in these relationships for 1O DCEPs at $P$=0.58 d. We derived relative individual distances for DCEPs in the LMC with a precision of $\sim$1 kpc, calculating the position angle of the line of nodes and inclination of the galaxy: $θ$=145.6$\pm$1.0 deg and $i$=25.7$\pm$0.4 deg. The bar and the disc are seen under different viewing angles. We calculated the ages of the pulsators, finding two main episodes of DCEP formation lasting $\sim$40 Myr which happened 93 and 159 Myr ago. Likely as a result of its past interactions with the SMC, the LMC shows a non-planar distribution, with considerable structuring: the bar is divided into two distinct portions, the eastern and the western displaced by more than 1 kpc from each other. Similar behaviour is shown by the spiral arms. The LMC disc appears "flared" and thick, with a disc scale height of $h\sim 0.97$ kpc. This feature can be explained by strong tidal interactions with the Milky Way and/or the Small Magellanic Cloud or past merging events with now disrupted LMC satellites.

Effect of pulse profile variations on measurement of eccentricity in orbits of Cen X-3 and SMC X-1

description: It has long been argued that better timing precision allowed by satelites like Rossi X-ray Timing Experiments (RXTE) will allow us to measure the orbital eccentricity and the angle of periastron of some of the bright persistent high mass X-ray binaries (HMXBs) and hence a possible measurement of apsidal motion in these system. Measuring the rate of apsidal motion allows one to estimate the apsidal motion constant of the mass losing companion star and hence allows for the direct testing of the stellar structure models for these giant stars present in the HMXBs. In the present paper we use the archival RXTE data of two bright persistent sources, namely Cen X-3 and SMC X-1, to measure the very small orbital eccentricity and the angle of periastron. We find that the small variations in the pulse profiles of these sources rather than the intrinsic timing accuracy provided by RXTE, limit the accuracy with which we can measure arrival time of the pulses from these sources. This influences the accuracy with which one can measure the orbital parameters, especially the very small eccentricity and the angle of periastron in these sources. The observations of SMC X-1 in the year 2000 were taken during the high flux state of the source and we could determine the orbital eccentricity and $ω$ using this data set.

description: Interactions occurring between malignant cells and stromal microenvironment greatly influence progression of breast cancer. In a previous study, we co-cultured mammary cancer cells exhibiting different degrees of metastatic potential (MDA-MB- 231>MCF-7) with fibroblasts isolated from breast healthy skin (normal fibroblasts, NFs) or breast tumor stroma (cancer-associated fibroblasts, CAFs). In this system, we demonstrated the influence exerted in particular by CAFs on malignant cells, leading to the acquisition of a more aggressive/invasive phenotype (i.e. reduced adhesion, epithelial-mesenchymal transition, enhanced plasma membrane fluidity and migration velocity/directness). In the present study, we evaluated the reciprocal effect of breast tumor cells and fibroblasts in co-culture on the expression of the main enzyme regulating the fatty acids membrane composition, Stearoyl-CoA desaturase 1 (SCD1). Abnormally high levels of SCD1 have been reported in different cancers and transformed cells and the enzyme has been recently raised to the role of key regulator of cell growth, programmed cell death and carcinogenesis. In our experience, Western blot analysis demonstrated a strong increase in SCD1 expression in both MCF-7 and MDA-MB-231 cells, resulting from their interaction with CAFs and, at a lesser extent, with NFs. High levels of SCD1 were also observed in both NFs and CAFs when co-cultured with MCF-7 cells. MDA-MB-231 cells more slightly up-regulated the enzyme expression in NFs or even induced a certain inhibition in CAFs. The fibroblast-triggered up-regulation of SCD1 in cancer cells could reasonably be considered the molecular event underlying the increase of membrane fluidity, previously observed in tumor cells co-cultured with NFs and, notably, with CAFs. This change might downstream promote the previously described increase in tumor cell motility.

Non invasive moderate loading in vivo and osteoarthritis development
Creators: name: Di Comite, Mariasevera

Publisher: name: Italian Journal of Anatomy and Embryology
Year: 2013
Subjects: Mechanical loading; osteoarthritis; VEGF

description: Mechanical loading is known to modify joint structure through a mechano-adaptative response and to increase proinflammatory cytokines, as IL-1β, modulating VEGF secretion by condrocytes1. VEGF is a potent angiogenic factor, also detectable in later stages of OA, able to increase matrix MMPs playing an important role in the development of OA2. The aim of this study is to evaluate “in vivo” changes of bone and cartilage leading to OA by means of nonsurgical intermittent moderate loading. Forty day-old mice was randomly divided into two groups of six animals each: sedentary and exercised. The exercised group was subjected to a treadmill running at 12m/min, two times a week for four weeks. The sedentary group did not undergo any physical training and was left free to walk inside the cages. After the sacrifice the femur heads were removed and processed for paraffin embedding. On 5μm coronal sections, safranine-O staining and immunostaining for IL-1 β, MMP-13 and VEGF was performed to evaluate: articular cartilage and subchondral bone trabeculae thickness; chondrocytes number/mm2; chondrocytes volume; % cell number expressing VEGF, IL-1β and MMP-13 in articular cartilage and bone. Significant increase of chondrocytes volume, VEGF and MMP-13 expression in cartilage was detected. These data seem indicate that our non-invasive experimental model could induce early alterations in articular cartilage only, confirming chondrocytes to play a central role in the pathogenesis of OA. Other alterations, such as articular cartilage cracking and thickening and sub-chondral bone sclerosis, would appear later.

description: Modeling event patterns is a central task in a wide range of disciplines. In applications such as studying human activity patterns, events often arrive clustered with sporadic and long periods of inactivity. Such heterogeneity in event patterns poses challenges for existing point process models. In this article, we propose a new class of clustered point processes that alternate between active and inactive states. The proposed model is flexible, highly interpretable, and can provide useful insights into event patterns. A composite likelihood approach and a composite EM estimation procedure are developed for efficient and numerically stable parameter estimation. We study both the computational and statistical properties of the estimator including convergence, consistency, and asymptotic normality. The proposed method is applied to Donald Trump’s Twitter data to investigate if and how his behaviors evolved before, during, and after the presidential campaign. Additionally, we analyze large-scale social media data from Sina Weibo and identify interesting groups of users with distinct behaviors.

description: We derive sharp, local and dimension dependent hypercontractive bounds on the Markov kernel of a large class of diffusion semigroups. Unlike the dimension free ones, they capture refined properties of Markov kernels, such as trace estimates. They imply classical bounds on the Ornstein-Uhlenbeck semigroup and a dimensional and refined (transportation) Talagrand inequality when applied to the Hamilton-Jacobi equation. Hypercontractive bounds on the Ornstein-Uhlenbeck semigroup driven by a non-diffusive Lévy semigroup are also investigated. Curvature-dimension criteria are the main tool in the analysis.

description: The meniscal vascular network changes during growth leading to the formation of a very heterogeneous tissue, with both a fibrous and cartilaginous matrix. This work focuses on the changes in the meniscus matrix and cell phenotype during growth. Menisci were harvested from young and adult pigs and cut into the two horns and the body. DNA and GAGs contents were determined; other samples were stained with SAFRANIN-O, for proteoglycan distribution, and contemporary stained for collagen 1 and 2; other samples were processed for collagen1 and 2 quantification by western blot analysis. Moreover, the body of each meniscus was divided into the inner, the intermediate and the external zone; each of them was processed for gene expression analysis. The obtained data showed a strong increase in GAGs production during growth as also observed by other author in cows (Ionescu et al, 2011), with an higher distribution in the inner area of the meniscus, in particular in the anterior horn; no differences were observed in the cellularity; collagen 2 deposition increased in the anterior horn during growth being confined mainly in the inner area, while collagen 1 deposition decreased being confined mainly in the external area. The analysis of the inner, intermediate and external zones showed that the intermediate one assumes a fibro-chondrocyte phenotype during growth becoming similar to the inner one. In conclusion, meniscus growth, from young to adult, is accompanied by a maturation of the anterior horn into a fibro-cartilaginous tissue; moreover, not only the whole inner but also the intermediate area of the meniscus develops fibro-cartilaginous properties during growth.

description: Results of long time observations of the pulsar B0950+08 are given. These observations were carried out at the LPA radio telescope at the frequency of 111 MHz from January of 2016 to May of 2019 (450 days). A strong variability in emission of this pulsar has been detected with changes of signal to noise ratios hundreds of times. Part of the long-time flux density variability can be explained by refractive scintillations in the interstellar medium. The existence of radiation between the interpulse (IP) and main pulse (MP) was confirmed. It was more powerful than at high frequencies. We detected the unusual interpulse and precursor (Pr) radiation on August 1, 2017. On the base of strong 65 interpulses we found the correlations between energies of IP and Pr and between the phase of IP and the distance Pr-IP. It is shown that the observed peculiarities of this pulsar can be explained in the frame of the aligned rotator model. We estimated distances of radiation levels from the center of the neutron star. The calculated value of the initial period of 0.2 sec means that not all pulsars are born with millisecond periods. The large age of the pulsar (6.8 millions of years) and the small angle between its magnetic moment and the rotation axis (less than 20$^{\circ}$) confirm the suggestion on the pulsar evolution to an alignment.

At present magnetic resonance imaging (MRI) is considered the best performing exam and it could be the first choice in the diagnosis of agenesia of the pericardium. Materials and Methods: A comprehensive review of dedicated books and PubMed literature was performed and three clinical cases have been analyzed.
 Results: We report three cases , one with partial and two with total agenesia of the left pericardium, seen at our Institute and diagnosed at MRI as unexpected findings. Discussion: The diagnosis of a congenital defect of the pericardium is challenging, even for expert radiologists, because this kind of deformity does not provide specific clinical nor conventional radiology findings. Nowadays, the most effective instrument for a certain diagnosis is MRI, interlocked with electrocardiography.

description: Modeling event patterns is a central task in a wide range of disciplines. In applications such as studying human activity patterns, events often arrive clustered with sporadic and long periods of inactivity. Such heterogeneity in event patterns poses challenges for existing point process models. In this article, we propose a new class of clustered point processes that alternate between active and inactive states. The proposed model is flexible, highly interpretable, and can provide useful insights into event patterns. A composite likelihood approach and a composite EM estimation procedure are developed for efficient and numerically stable parameter estimation. We study both the computational and statistical properties of the estimator including convergence, consistency, and asymptotic normality. The proposed method is applied to Donald Trump’s Twitter data to investigate if and how his behaviors evolved before, during, and after the presidential campaign. Additionally, we analyze large-scale social media data from Sina Weibo and identify interesting groups of users with distinct behaviors.

description: The emerging research into spatial sound as a medium, in conjunction with recent technical developments in spatial sound processing and acoustic holography, provides a new field of study that may further the understanding of the principles of sound wave propagation and how to make use of its potential effects on human wellbeing. Prior studies conducted during recent years show that spatial coherence of sound waves may have a distinct effect on harnessing energy in natural systems, such as improved homeostasis in the human body. Spatial coherence of sound is understood as the alignment of sound waves in specific symmetrical patterns and the amplification of associated harmonic spectra as a result, which coincides with an observed improvement of the physiological and psychological state of subjects exposed to the sound waves. We consider these aspects to be intertwined as part of a unified non-discrete system, meaning the connectome of various natural systems bound by the fundamental principle of syntropy (negentropy). This notion informs and gives rise to the hypothesis that spatial projection of sound may provide a means for Acoustic Effector Stimulation (AES) to help restore, maintain and optimize balance in cell organisms, implying potential applications for treatment and prevention of pathological conditions associated with disease and trauma.

Possible treatment of the Ghost states in the Lee-Wick Standard Model

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

description: Very recently, the Lee-Wick standard model has been introduced as a non-SUSY extension of the Standard model which solves the Hierarchy problem. In this model, each field kinetic term attains a higher derivative term. Like any Lee-Wick theory, this model suffers from existence of Ghost states. In this work, we consider a prototype scalar field theory with its kinetic term has a higher derivative term, which mimics the scalar sector in the Lee-Wick Standard model. We introduced an imaginary auxiliary field to have an equivalent non-Hermitian two-field scalar field theory. We were able to calculate the positive definite metric operator $η$ in quantum mechanical and quantum field versions of the theory in a closed form. While the Hamiltonian is non-Hermitian in a Hilbert space with the Dirac sense inner product, it is Hermitian in a Hilbert space endowed by the inner product $$ as well as having a correct-sign propagator (no Lee-Wick fields). Besides, the obtained metric operator also diagonalizes the Hamiltonian in the two fields (no mixing). Moreover, the Hermiticity of $η$ constrained the two Higgs masses to be related as $M>2m$, which has been obtained in another work using a very different regime and thus supports our calculation. Also, an equivalent Hermitian (in the Dirac sense) Hamiltonian is obtained which has no Ghost states at all, which is a forward step to make the Lee-Wick theories more popular among the Physicists.

description: The dystrophin glycoprotein complex and the vinculin-talin-integrin system are two costameric protein systems which play several and important roles in muscle tissue. In particular, sarcoglycans and integrins, by a bidirectional signaling, seem to cooperate in lateral transmission of contraction forces. These protein systems have been well described in human muscle tissue and also in primates, as chimpanzee. Our previous study performed on masseter muscle of baboon, have shown interesting results about the presence of negative fibers for sarcoglycans and integrins in low dominance baboons, a social group characterized by a major aggressiveness than high dominance. These results suggested as that in low dominance baboons alternative isoforms of sarcoglycans and integrins could be exist. In the present study we continued the investigation of the entire protein complexes, not only sarcoglycans and integrins, in another type of skeletal muscle of baboons, the sternocleidomastoid both in high and in low dominance. Results have shown that also in sternocleidomastoid of low dominance baboons fibers negative for the tested proteins exist. These results confirm our previous findings on masseter of baboon and support our hypothesis about the presence of alternative protein systems which could be correlated with the aggressiveness degree and which could be involved in evolution of the species.

Oxygen in dense interstellar gas - the oxygen abundance of the star forming core rho Oph A

description: Oxygen is the third most abundant element in the universe, but its chemistry in the interstellar medium is still not well understood. In order to critically examine the entire oxygen budget, we attempt here initially to estimate the abundance of atomic oxygen, O, in the only one region, where molecular oxygen, O2, has been detected to date. We analyse ISOCAM-CVF spectral image data toward rho Oph A to derive the temperatures and column densities of H2 at the locations of ISO-LWS observations of two [OI] 3P_J lines. The intensity ratios of the (J=1-2) 63um to (J=0-1) 145um lines largely exceed ten, attesting to the fact that these lines are optically thin. This is confirmed by radiative transfer calculations, making these lines suitable for abundance determinations. For that purpose, we calculate line strengths and compare them to the LWS observations. Excess [OI] emission is observed to be associated with the molecular outflow from VLA 1623. For this region, we determine the physical parameters, T and N(H2), from the CAM observations and the gas density, n(H2), is determined from the flux ratio of the [O I]63um and [O I]145um lines. For the oxygen abundance, our analysis leads to essentially three possibilities: (1) Extended low density gas with standard ISM O-abundance, (2) Compact high density gas with standard ISM O-abundance and (3) Extended high density gas with reduced oxygen abundance, [O/H] ~ 2E-5. As option (1) disregards valid [O I] 145um data, we do not find it very compelling; we favour option (3), as lower abundances are expected as a result of chemical cloud evolution, but we are not able to dismiss option (2) entirely. Observations at higher angular resolution than offered by the LWS are required to decide between these possibilities.

Transit value capture finance : a global review towards measuring monetary efficiency
Creators: name: Olajide, Oladapo (Alex)
Publisher: name: The University of British Columbia
Year: 2017

description: Land Value Capture (LVC) is an alternative method of transit finance that recovers land value gains (an unearned income) enjoyed by transit proximate properties, for transit project funding purposes. The application of transit value capture funding is predicated primarily on transit induced land value increases (capitalization) enjoyed by private land owners, and the increasing funding responsibilities of transit agencies globally. There are two approaches to land value capture (LVC); they include Development Based Land Value Capture (DBLVC) and Taxation Based Land Value Capture (TBLVC). The former leverages land assets and development rights in transit proximate areas in order to meet a transportation funding objective, whereas the latter leverages and applies taxation powers and instruments available to transit agencies and governments on transit benefitting properties. DBLVC instruments discussed in this report include: Direct Property Development, Joint Property Development, Land Sales, Land Lease Agreements, Land Readjustments, and Urban Redevelopment Schemes. Direct Property Development and Joint Property Development are highlighted in this report by conducting case studies on Nanchang, China and Hong Kong Mass Transit Railway (MTR) Corporation respectively. TBLVC instruments discussed in this report include: Tax increment financing, Special Assessments, Land Value Tax, Betterment Charges, Transportation Impact Fees, and Station Connection Fees. Betterment Charges are highlighted in this report by conducting a case study on London’s Crossrail Business Rate Supplement (BRS). Using limited public financial data, the financial performance of the three highlighted LVC case studies – Nanchang Direct Property Development program, Hong Kong MTR Rail plus Property program, and London Crossrail BRS - are assessed using the Transit Land Value Capture Cost Recovery Ratio (TLVCCR) – a ratio comparing the implementation cost of LVC mechanisms to revenues generated. In terms of distinct advantages: • DBLVC through property development has a higher revenue potential • DBLVC involves relatively low political risk • DBLVC is based on partnership between agency and private land developers and owners in sharing land value gains through mutually beneficial land and development transactions as opposed to exactions • TBLVC requires low financial cost of implementation (land acquisition not incurred) • TBLVC involves low financial risk during implementation • TBLVC can be applied multiple times over a long period of time to transit benefitting properties in order to generate significant revenues for transit project funding. The critical success factors and supporting conditions required to successfully apply transit value capture finance in any context include: Feasibility, Equity, Efficiency, and Revenue Capacity.

description: The first example of an empirically manifested quasi dynamical symmetry trajectory in the interior of the symmetry triangle of the Interacting Boson Approximation model is identified for large boson numbers. Along this curve, extending from SU(3) to near the critical line of the first order phase transition, spectra exhibit nearly the same degeneracies that characterize the low energy levels of SU(3). This trajectory also lies close to the Alhassid-Whelan arc of regularity, the unique interior region of regular behavior connecting the SU(3) and U(5) vertices, thus offering a possible symmetry-based interpretation of that narrow zone of regularity amidst regions of more chaotic spectra.

Linking place of employment & health living : the impact of the built environment near workplaces on physical activity, body mass index & sedentary driving time
Creators: name: Fox, Eric Herschel
Publisher: name: The University of British Columbia
Year: 2017

description: In the face of increasing rates of chronic diseases among working adults, urban planners and public health professionals have investigated the extent to which transportation systems, land use patterns and urban design have contributed to sedentary lifestyles. Although many studies have explored the relationships between health and the built environment for neighbourhoods around residences, few have analyzed urban form near workplaces. One of the limitations of health studies on workplaces is that the focus has primarily been on internal building environments such as the presence of fitness facilities, rather than the built environment around the worksite. The place of employment is an important setting for assessing walk environments because of the large amount of time spent at work, the mode of transportation used for regular commuting, and travel around the workplace during and outside of work hours. Despite this relevance, a limited understanding exists about the built environment at worksites and its impact on health and physical activity.

description: We study the field dependence of the antiferromagnetic spin-1/2 Heisenberg model on the square lattice by means of exact diagonalizations. In a first part, we calculate the spin-wave velocity, the spin-stiffness, and the magnetic susceptibility and thus determine the microscopic parameters of the low-energy long-wavelength description. In a second part, we present a comprehensive study of dynamical spin correlation functions for magnetic fields ranging from zero up to saturation. We find that at low fields, magnons are well defined in the whole Brillouin zone, but the dispersion is substantially modified by quantum fluctuations compared to the classical spectrum. At higher fields, decay channels open and magnons become unstable with respect to multi-magnon scattering. Our results directly apply to inelastic neutron scattering experiments.

description: Background. Human Natural killer (NK) cells are characterized by NK cell receptors (NKRs) with inhibitory and activatory function that finely control their functional activities. In particular, they express inhibitory receptors for MHC class I molecules, named killer cell immunoglobulin (Ig)-like receptors (KIRs) and C-type lectin CD94-CD159a, and many triggering molecules like NKp30, NKp44, NKp46, (called natural cytotoxicity receptors, NCRs), NKG2D, CD161, and CD244. The majority of peripheral blood human NK cells are characterized by a phenotype with a low density expression of CD56 (CD56dim) and a high expression of CD16 (CD16bright), whereas a minority (approximately 5–10%) shows a bright expression of CD56 (CD56bright). This latter NK subset presents relatively high expression of some cytokine receptors (CD117 and CD25) and the CD94-CD159a heterodimeric inhibitory receptor. CD56bright NK cells are widely expressed in lymphoid tissues and can be generated from CD34+ cells when cultured with combinations of flt-3 ligand (FL) or stem cell factor plus IL-15 or IL-2. During their development, NK cells sequentially acquire many different antigens but there is still limited knowledge on differentiation antigens able to identify immature human NK cells and the specific sequence through which developing NK cells acquire the expression of NKR.Methods. NK cells obtained from human CD34+ hematopoietic progenitor cells after 30-day culture with FL plus IL-15, or from peripheral and umbilical cord blood samples were characterized.Results. Virtually, all CD56 NK cells differentiated in vitro expressed CD117, CD25, NCRs, NKG2D, CD161, and CD244, while only a subset expressed CD18-CD11a (LFA-1), and CD94 molecule, defining an immature CD56bright/NCRs+/NKG2D+/LFA-1-/CD94- subset. Another small subset of cells expressing CD94 but not LFA-1 integrin was also identified, suggesting that during NK differentiation LFA-1 might be upregulated later than CD94. To verify this hypothesis in vivo, we evaluated the NK cell expression of LFA-1 in both peripheral and umbilical cord blood samples. Interestingly, in these blood fluids, we have identified a lineage negative CD34-/LFA-1low/NKp46dim/NKG2Ddim/CD94- subset that resembled an immature stage of NK cells present in lymph nodes. Conclusions. Altogether, the results indicate that CD18-CD11a integrin, as well as CD11b in mice, may be a useful marker to identify immature stages of human NK cell differentiation.
