description: Three solenoids have been wound and with MgB2 strand and tested for transport properties. One of the coils was wound with Cu-sheathed monofilamentary strand and the other two with a seven filament strand with Nb-reaction barriers, Cu stabilization, and an outer monel sheath. The wires were first S-glass insulated, then wound onto an OFHC Cu former. The coils were then heat treated at 675C/30 min (monofilamentary strand) and 700C/20 min (multifilamentary strand). Smaller (1 m) segments of representative strand were also wound into barrel-form samples and HT along with the coils. After HT the coils were epoxy impregnated. Transport Jc measurements were performed at various taps along the coil lengths. Measurements were made initially in liquid helium, and then as a function of temperature up to 30 K. Homogeneity of response along the coils was investigated and a comparison to the short sample results was made. Each coil contained more than 100 m of 0.84-1.01 mm OD strand. One of the 7 strand coils reached 222 A at 4.2 K, self field, with a Jc of 300 kA/cm2 in the SC and a winding pack Je of 23 kA/cm2. At 20 K these values were 175 kA/cm2 and 13.4 kA/cm2. Magnet bore fields of 1.5 T and 0.87 T were achieved at 4.2 K and 20 K, respectively. The other multifilamentary coil gave similar results.

description: Spin-fluctuation-mediated unconventional superconductivity can emerge at the border of magnetism, featuring a superconducting order parameter that changes sign in momentum space. Detection of such a sign-change is experimentally challenging, since most probes are not phase-sensitive. The observation of a spin resonance mode (SRM) from inelastic neutron scattering is often seen as strong phase-sensitive evidence for a sign-changing superconducting order parameter, by assuming the SRM is a spin-excitonic bound state. Here, we show that for the heavy fermion superconductor CeCoIn$_5$, its SRM defies expectations for a spin-excitonic bound state, and is not a manifestation of sign-changing superconductivity. Instead, the SRM in CeCoIn$_5$ likely arises from a reduction of damping to a magnon-like mode in the superconducting state, due to its proximity to magnetic quantum criticality. Our findings emphasize the need for more stringent tests of whether SRMs are spin-excitonic, when using their presence to evidence sign-changing superconductivity.

description: We observed the main core F of the rho Ophiuchi cloud, an active star-forming region located at ~140 pc, using XMM-Newton with an exposure of 33 ks. We detect 87 X-ray sources within the 30' diameter field-of-view of the it EPIC imaging detector array. We cross-correlate the positions of XMM-Newton X-ray sources with previous X-ray and infrared (IR) catalogs: 25 previously unknown X-ray sources are found from our observation; 43 X-ray sources are detected by both XMM-Newton and Chandra; 68 XMM-Newton X-ray sources have 2MASS near-IR counterparts. We show that XMM-Newton and Chandra have comparable sensitivity for point source detection when the exposure time is set to ~30 ks for both. We detect X-ray emission from 7 Class I sources, 26 Class II sources, and 17 Class III sources. The X-ray detection rate of Class I sources is very high (64 %), which is consistent with previous Chandra observations in this area. We propose that 15 X-ray sources are new class III candidates, which doubles the number of known Class III sources, and helps to complete the census of YSOs in this area. We also detect X-ray emission from two young bona fide brown dwarfs, GY310 and GY141, out of three known in the field of view. GY141 appears brighter by nearly two orders of magnitude than in the Chandra observation. We extract X-ray light curves and spectra from these YSOs, and find some of them showed weak X-ray flares. We observed an X-ray flare from the bona fide brown dwarf GY310. We find as in the previous Chandra observation of this region that Class I sources tend to have higher temperatures and heavier X-ray absorptions than Class II and III sources.

description: We present recent results on the operation of gas-avalanche detectors comprising a cascade of gas electron multipliers (GEMs) and Micro-Hole and Strip Plates (MHSPs) multiplier operated in reversed-bias (R-MHSP) mode. The operation mechanism of the R-MHSP is explained and its potential contribution to ion-backflow (IBF) reduction is demonstrated. IBF values of 4E-3 were obtained in cascaded R-MHSP and GEM multipliers at gains of about 1E+4, though at the expense of reduced effective gain in the first R- MHSP multiplier in the cascade.

Developmental changes in pontine and adrenergic influences on the respiratory rhythm generator in neonatal rats
Creators: name: Corcoran, Andrea E.
Publisher: name: University of British Columbia
Year: 2009

description: In neonatal rats, the pons is known to modulate the respiratory rhythm. Much of the influence is inhibitory and has been attributed to adrenergic inputs originating from the A5 nuclei of the pons. Nonetheless, there are conflicting reports as to how pontine influences change throughout early development in rats. To identify the changes in pontine influence and adrenergic inputs, the in vitro brainstem-spinal cord preparation was used in rats aged PO, P2 and P4 (0, 2 and 4 post-natal days). First, a series of validation experiments was carried out in order to establish the viability and stability of the preparations. PO to P4 preparations were stable (both in Active breathing frequency and burst amplitude) during the first 3 hours of recording. In the second set of experiments, we transected the pons to determine breathing rates with and without pontine inputs. Thirdly, αl and α2 adrenoreceptor antagonists (Prazosin and Rauwolscine, respectively) were applied to either the pons or medulla, and in the presence or absence of pontine inputs, to determine if results found in the pons transections experiments could be explained by changes in adrenergic inputs. Our pontine transection results showed that at PO, the pons exerted an excitatory drive on the medullary respiratory rhythm generator. At P2, the pons appeared to have no effect on breathing frequency. At P4, the pons switched to providing an inhibition on the rhythm generator. The changes observed with transection of the pons cannot be explained solely by removal of adrenergic influences and must arise from non-adrenergic influences coming from the pons. Blocking α2 adrenoreceptors in the medulla both in the presence and absence of the pons resulted in a decrease in respiratory frequency at all ages. However, medullary αl-adrenoreceptor blockade had no significant effect when the pons was still present. Similarly, blocking pontine α2 adrenoreceptors (autoreceptors) did not significantly change breathing frequency. Furthermore, pharmacological blockade of both αl - and α2- medullary adrenoreceptors had a more pronounced effect when the pons was absent, suggesting that the adrenergic inputs are originating not only from the pons, but the medulla itself. Full explanation of the mechanisms underlying the switch from an excitatory pons to one that is inhibitory likely includes changes in several other neuromodulatory systems, and requires further studies using carefully and narrowly defined age groups.

description: Background: In the United States, the number of new cases of hepatitis C virus infection has risen in recent years, driven largely by transmission among young white adults in their 20s and 30s. Herein, we report an integrated analysis of participants with hepatitis C virus infection aged ≤35 years from 12 phase II/III clinical trials of elbasvir/grazoprevir. Methods: Treatment-naive and -experienced adults with hepatitis C virus genotype 1 or 4 infection received elbasvir (50 mg/day)/grazoprevir (100 mg/day) for 12 weeks without ribavirin. Analyses were stratified according to participant age (≤35 years vs >35 years). The primary endpoint was sustained virologic response (hepatitis C virus RNA Results: Sustained virologic response was achieved by 98.9% (271/274) of participants aged ≤35 years and by 96.9% (2093/2160) aged >35 years. Three participants aged ≤35 years with genotype 1b infection relapsed. Eight participants with genotype 1a infection and baseline non-structural protein 5 A resistance-associated substitutions achieved sustained virologic response. Similarly, all 85 participants aged ≤35 years with genotype 1a infection and no baseline non-structural protein 5 A resistance-associated substitutions achieved sustained virologic response. Safety was favorable, with the incidence of drug-related adverse events similar in younger and older participants (30.1% vs 30.6%). One participant (0.4%) aged ≤35 years and 15 participants (0.7%) aged >35 years discontinued treatment owing to adverse events. Conclusions: Elbasvir/grazoprevir for 12 weeks was safe and highly effective in participants aged ≤35 years with hepatitis C virus genotype 1 or 4 infection.

description: Data on low-pT hadronic spectra are widely regarded as evidence of a hydrodynamic expansion in nucleus-nucleus collisions. In this interpretation, different hadron species emerge from a common medium that has built up a strong collective velocity field. Here, we show that the existence of a collective flow field implies characteristic modifications of high-pT parton fragmentation. We generalize the formalism of parton energy loss to the case of flow-induced, oriented momentum transfer. We also discuss how to embed this calculation in hydrodynamic simulations. Flow effects are found to result generically in characteristic asymmetries in the eta-phi-plane of jet energy distributions and of multiplicity distributions associated to high-pT trigger particles. But collective flow also contributes to the medium-induced suppression of single inclusive high-pT hadron spectra. In particular, we find that low-pT elliptic flow can induce a sizeable additional contribution to the high-pT azimuthal asymmetry by selective elimination of those hard partons which propagate with significant inclination against the flow field. This reduces at least partially the recently observed problem that models of parton energy loss tend to underpredict the large azimuthal asymmetry v2 of high-pT hadronic spectra in semi-peripheral Au+Au collisions.

description: O agronegócio da avicultura pernambucana é de grande importância na geração de ocupação, emprego e renda, sobretudo no meio rural. O estado não dispõe de milho e soja para fazer o frango, tem que trazer essas matérias primas de regiões produtoras no país, sendo o milho muitas vezes importado. Mesmo assim, ocupa lugar de destaque no cenário nacional como produtor de ovos e de carne de frango. Para entender essa situação o trabalho analisa as estratégias de grandes unidades industriais a partir de suas situações no ambiente. A base teórica da análise é assentada nas abordagens SWOT, Cadeias de Valores, e Grupos Estratégicos. Registra-se que as empresas adotam estratégias compatíveis com suas possibilidades dadas, pelas suas condições internas e externamente vêm tendo um grande apoio de políticas publicas, contam com o crescimento da economia e o aumento do consumo desse tipo de carne na região nordestina. --------------------------------------------The agribusiness of poultry in Pernambuco is very important in the generation of occupation, employment and income, especially in rural areas. The state has no corn and soybeans to make the chicken, and has to bring those materials from other producing areas in the country, and the corn is often imported. Therefore, occupies high place on the national scene as a producer of eggs and chicken meat. To understand this situation this work examines the strategies of large industrial units from their positions on the environment. The theoretical basis of the analysis is set on the approaches of SWOT, Chains of Values and Strategic Groups. Compa-nies adopt strategies consistent with their possibilities that are given by their internal condi-tions, and externally are having a great support of public policies, considering the growth of the economy and increase of the consumption of such meat in the Northeast of Brazil.

description: Applying machine learning (ML) on multivariate time series data has growing popularity in many application domains, including in computer system management. For example, recent high performance computing (HPC) research proposes a variety of ML frameworks that use system telemetry data in the form of multivariate time series so as to detect performance variations, perform intelligent scheduling or node allocation, and improve system security. Common barriers for adoption for these ML frameworks include the lack of user trust and the difficulty of debugging. These barriers need to be overcome to enable the widespread adoption of ML frameworks in production systems. To address this challenge, this paper proposes a novel explainability technique for providing counterfactual explanations for supervised ML frameworks that use multivariate time series data. The proposed method outperforms state-of-the-art explainability methods on several different ML frameworks and data sets in metrics such as faithfulness and robustness. The paper also demonstrates how the proposed method can be used to debug ML frameworks and gain a better understanding of HPC system telemetry data.

description: We have measured the polarized Raman scattering spectra of Cd2Re2O7, the first superconducting pyrochlore, as a function of temperature. For temperatures below the cubic-to-tetragonal structural phase transition (SPT) at 200K, a peak with B1 symmetry develops at zero frequency with divergent intensity. We identify this peak as the first observation of the Goldstone phonon in a crystalline solid. The Goldstone phonon is a collective excitation that exists due to the breaking of the continuous symmetry with the SPT. Its emergence coincides with that of a Raman-active soft mode. The order parameter for both features derives from an unstable doubly-degenerate vibration (with Eu symmetry) of the O1 atoms which drives the SPT.

description: Similarity between the weak interaction properties of quarks and leptons has led to suggestions that the origin of lepton mixing angles may be related to those of quarks. In this paper, we present a gauge model based on $SU(2)_L \times SU(2)_R\times SU(4)_c$ group that leads to a new form for the quark lepton complementarity which predicts the solar neutrino mixing angle in terms of the Cabibbo angle for the case of inverted mass hierarchy for neutrinos. We also indicate how these ideas can be implemented in an $E_6$ inspired trinification $SU(3)_C \times SU(3)_L \times SU(3)_R$ model, which is more closely allied to string theory by the AdS/CFT correspondence.

description: O pólo Petrolina-Juazeiro possui uma economia fortemente baseada na agricultura irrigada; identificada como única alternativa de transformação econômica e social da região, uma vez que esta enfrenta uma assombrosa realidade de seca. Estas constatações sobre irrigação relativas à sua instituição na micro região do semi-árido nordestino são relativamente recentes; sendo a própria experiência do pólo um baluarte delas. Mas a sustentabilidade da atividade na região tem sido questionada, principalmente devido à sua forte dependência ambiental, em particular do recurso hídrico. Ao se basear na irrigação para produção agrícola, e ser esta a propulsora dos efeitos multiplicadores da renda regional, pode-se dizer que o desenvolvimento do pólo é altamente dependente das condições produtivas da terra e da disponibilidade e qualidade da água do rio São Francisco. Este artigo tem como objetivo testar a hipótese da insustentabilidade, utilizando-se, para isto, do cálculo do ISEW para municípios selecionados do pólo. É proposta uma metodologia de cálculo dos diversos itens do ISEW em nível municipal, fazendo-se as adaptações necessárias devido ao nível de agregação dos dados e de disponibilidade dos dados. Os resultados são ainda parciais, mas tem se mostrado coerentes com os resultados obtidos para outros estudos.

description: We analyzed the results of non-linear resistive magnetohydrodynamical (MHD) simulations of jet formation to study the acceleration mechanism of axisymmetric, resistive MHD jets. The initial state is a constant angular momentum, polytropic torus threaded by weak uniform vertical magnetic fields. The time evolution of the torus is simulated by applying the CIP-MOCCT scheme extended for resistive MHD equations. We carried out simulations up to 50 rotation period at the innermost radius of the disk created by accretion from the torus. The acceleration forces and the characteristics of resistive jets were studied by computing forces acting on Lagrangian test particles. Since the angle between the rotation axis of the disk and magnetic field lines is smaller in resistive models than in ideal MHD models, magnetocentrifugal acceleration is smaller. The effective potential along a magnetic field line has maximum around $z \sim 0.5r_0$ in resistive models, where $r_0$ is the radius where the density of the initial torus is maximum. Jets are launched after the disk material is lifted to this height by pressure gradient force. Even in this case, the main acceleration force around the slow magnetosonic point is the magnetocentrifugal force. The power of the resistive MHD jet is comparable to the mechanical energy liberated in the disk by mass accretion. Joule heating is not essential for the formation of jets.

description: The discovery of the anomalous Hall effect (AHE) in bulk metallic antiferromagnets (AFMs) motivates the search of the same phenomenon in two-dimensional (2D) systems, where a quantized anomalous Hall conductance can in principle be observed. Here, we present experiments on micro-fabricated devices based on Co$_{1/3}$NbS$_2$, a layered AFM that was recently found to exhibit AHE in bulk crystals below the Néel temperature T$_N$ = 29 K. Transport measurements reveal a pronounced resistivity anisotropy, indicating that upon lowering temperature the electronic coupling between individual atomic layers is increasingly suppressed. The experiments also show an extremely large anomalous Hall conductivity of approximately 400 S/cm, more than one order of magnitude larger than in the bulk, which demonstrates the importance of studying the AHE in small exfoliated crystals, less affected by crystalline defects. Interestingly, the corresponding anomalous Hall conductance, when normalized to the number of contributing atomic planes, is $\sim \, 0.6 \; e^2/h$ per layer, approaching the value expected for the quantized anomalous Hall effect. The observed strong anisotropy of transport and the very large anomalous Hall conductance per layer make the properties of Co$_{1/3}$NbS$_2$ compatible with the presence of partially filled topologically non-trivial 2D bands originating from the magnetic superstructure of the antiferromagnetic state. Isolating atomically thin layers of this material and controlling their charge density may therefore provide a viable route to reveal the occurrence of the quantized AHE in a 2D AFM.

description: Evidence suggests that integrase strand transfer inhibitors (INSTIs) are associated with greater weight gain than other antiretrovirals. This real-world study compares weight/body mass index (BMI) change between insured US patients with human immunodeficiency virus (HIV-1) initiating a protease inhibitor (PI) or INSTI. A retrospective longitudinal study was conducted using Decision Resources Group’s Real World Data Repository (7/17/2017-6/1/2019). Adult patients with HIV-1 who initiated a new PI or INSTI on or after 7/17/2018 (index date) and had ≥12 months of continuous pre-index clinical activity were included. Baseline characteristics were balanced using inverse probability of treatment weighting. The proportion of patients with ≥5% weight/BMI increases and mean weight/BMI change from pre- to post-index were compared using odds ratios (ORs) and mean differences (MDs). 20,367 patients (9993 PI, 10,374 INSTI) were included (mean age = 50 years; ∼30% females). Pre- and post-index weight and BMI measurements were available in 429 and 430 PI patients, and 397 and 383 INSTI patients, respectively (mean time between index and post-index measurements: ∼7 months). The PI cohort was 39%/49% less likely to experience ≥5% weight/BMI increase than the INSTI cohort, respectively (OR [≥5% weight gain] = 0.61; p = .014; OR [≥5% BMI gain] = 0.51; p < .001). Mean weight/BMI gain was significantly lower in the PI cohort than the INSTI cohort (weight MD = –1.90 kg [–4.19 lbs], BMI MD = –0.61kg/m2; both p < .001). Relative to INSTI, patients initiating a new PI were less likely to experience ≥5% weight/BMI gain post-index. Additionally, mean weight/BMI gain was lower in the PI than in the INSTI cohort.

description: We use cosmological SPH simulations to investigate the effects of mergers and interactions on the formation of the bulge and disc components of galactic systems. We find that secular evolution during mergers seems to be a key process in the formation of stable disc-bulge systems with observational counterparts and contributes to establish the fundamental relations observed in galaxies. Our findings suggest that the secular evolution phase couples the formation mechanisms of the bulge and disc components. According to our results, depending on the particular stability properties and merger parameters, violents events could drive a morphological loop in which the outcome could be a disc or a spheroid.

description: We present a detailed analysis of the time series of time-stamped neutron counts obtained by single-neutron interferometry. The neutron counting statistics display the usual Poissonian behavior, but the variance of the neutron counts does not. Instead, the variance is found to exhibit a dependence on the phase-shifter setting which can be explained by a probabilistic model that accounts for fluctuations of the phase shift. The time series of the detection events exhibit long-time correlations with amplitudes that also depend on the phase-shifter setting. These correlations appear as damped oscillations with a period of about 2.8 s. By simulation, we show that the correlations of the time differences observed in the experiment can be reproduced by assuming that, for a fixed setting of the phase shifter, the phase shift experienced by the neutrons varies periodically in time with a period of 2.8 s. The same simulations also reproduce the behavior of the variance. Our analysis of the experimental data suggests that time-stamped data of singleparticle interference experiments may exhibit transient features that require a description in terms of non-stationary processes, going beyond the standard quantum model of independent random events.

description: We have employed natural guide star adaptive optics (AO) on the Keck II telescope to obtain near-infrared (H and K') images of three field galaxies, each of redshift greater than 0.5. These are among the highest-redshift non-active disk galaxies to be imaged with AO. Each of the galaxies was chosen because it had been observed previously with the Hubble Space Telescope (HST) Wide Field Planetary Camera 2 (WFPC2) by others. Our AO images in the near infrared (NIR) closely match both the depth and high spatial resolution of those optical data. Combining the archival V and I data with our new H and K' images potentially produces a long wavelength baseline at uniform resolution. The NIR data probe emission well longward of the 4000-Angstrom break at these redshifts, and provide stellar fluxes less contaminated by dust. We fit two-dimensional galaxy bulge-plus-disk models simultaneously in all bands, and compare stellar-population-synthesis modeling to the photometry of these separated components. This is an initial foray into combining HST and AO imaging to produce a high spatial-resolution multi-color dataset for a large sample of faint galaxies. Our pilot program shows that NIR AO images from large ground-based observatories, augmented by HST images in the optical, can in principle provide a powerful tool for the analysis of faint field galaxies. However, the AO data S/N will have to be increased, and AO PSFs need to be controlled more carefully than they were here.

description: This position paper proposes the Foundational Helix Model (FHM) as a paradigm shift in innovation theory, critically reconfiguring the Quintuple Helix Innovation Model. While the QHIM includes the natural environment as a fifth helix, the FHM asserts that ecological systems must be understood not as an equal stakeholder, but as the foundational substrate upon which academia, industry, government, and civil society depend. The model advocates for regenerative innovation, place-based ecological literacy, and systemic awareness. Ireland is presented as an ideal testing ground for this approach due to its rich biodiversity, civic engagement, and progressive environmental policy frameworks. The FHM offers a strategic lens for designing Living Labs, Horizon Europe proposals, and cross-sectoral climate action rooted in ecological realities.
A model for the collapse of the edge when two transitions routes compete

description: The transition to turbulence in many shear flows proceeds along two competing routes, one linked with finite-amplitude disturbances and the other one originating from a linear instability, as in e.g. boundary layer flows. The dynamical systems concept of edge manifold has been suggested in the subcritical case to explain the partition of the state space of the system. This investigation is devoted to the evolution of the edge manifold when a linear stability is added in such subcritical systems, a situation poorly studied despite its prevalence in realistic fluid flows. In particular the fate of the edge state as a mediator of transition is unclear. A deterministic three-dimensional model is suggested, parametrised by the linear instability growth rate. The edge manifold evolves topologically, via a global saddle-loop bifurcation, from the separatrix between two attraction basins to the mediator between two transition routes. For larger instability rates, the stable manifold of the saddle point increases in codimension from 1 to 2 after an additional local saddle node bifurcation, causing the collapse of the edge manifold. As the growth rate is increased, three different regimes of this model are identified, each one associated with a flow case from the recent hydrodynamic literature. A simple nonautonomous generalisation of the model is also suggested in order to capture the complexity of spatially developing flows.

description: Objective: Growing evidence suggests that the use of integrase strand transfer inhibitors (INSTIs) is associated with greater weight gain than other antiretroviral therapies; as a result, United States (US)-based treatment guidelines were updated to reflect this and raise clinicians’ awareness. This real-world study describes demographics and compares weight/body mass index (BMI) change between insured US patients with human immunodeficiency virus (HIV-1) initiating a protease inhibitor (PI) or INSTI. Methods: A retrospective longitudinal study was conducted using Decision Resources Group’s Real World Data Repository (7/17/2017-6/1/2019). Adult patients with HIV-1 who initiated a new PI or INSTI on or after 7/17/2018 (index date) and had ≥12 months of continuous pre-index clinical activity were included. Baseline characteristics were balanced using inverse probability of treatment weighting. The proportion of patients with ≥5% weight/BMI increases and mean weight/BMI change from pre- to post-index were evaluated. Outcomes were compared using odds ratios (ORs) and mean differences (MDs). Results: 20,367 patients (9,993 PI and 10,374 INSTI) were included. Baseline characteristics were well-balanced (mean age =50 years; ∼30% females in both cohorts). Pre- and post-index weight and BMI measurements were available in 429 and 430 PI patients, and 397 and 383 INSTI patients, respectively. Mean time between index and last post-index measurements was ∼7 months. Patients using PI-based regimens were 39% and 49% less likely to experience ≥5% weight and BMI increase than those using INSTI-based regimens, respectively (OR [≥5% weight gain] = 0.61; p = 0.014; OR [≥5% BMI gain] = 0.51; p 2; p Conclusions: Relative to patients initiating a new INSTI, patients initiating a new PI were less likely to experience ≥5% weight/BMI gain post-index. Additionally, mean weight/BMI gain was lower in the PI than in the INSTI cohort.
Radiative transitions of high energy neutrino in dense matter

description: The quantum theory of the ``spin light'' (electromagnetic radiation emitted by a massive neutrino propagating in dense matter due to the weak interaction of a neutrino with background fermions) is developed. In contrast to the Cherenkov radiation, this effect does not disappear even if the medium refractive index is assumed to be equal to unity. The formulas for the transition rate and the total radiation power are obtained. It is found out that radiation of photons is possible only when the sign of the particle helicity is opposite to that of the effective potential describing the interaction of a neutrino (antineutrino) with the background medium. Due to the radiative self-polarization the radiating particle can change its helicity. As a result, the active left-handed polarized neutrino (right-handed polarized antineutrino) converting to the state with inverse helicity can become practically ``sterile''. Since the sign of the effective potential depends on the neutrino flavor and the matter structure, the ``spin light'' can change a ratio of active neutrinos of different flavors. In the ultra relativistic approach, the radiated photons averaged energy is equal to one third of the initial neutrino energy, and two thirds of the energy are carried out by the final ``sterile'' neutrinos. This fact can be important for the understanding of the ``dark matter'' formation mechanism on the early stages of evolution of the Universe.

Small airway remodeling in mice : analysis of growth factor gene expression following exposure to cigarette smoke
Creators: name: Coulthard, Tonya
Publisher: name: University of British Columbia
Year: 2009

description: Chronic obstructive pulmonary disease (COPD) results in progressive airflow obstruction, characterized by shortness of breath and chronic cough, and is most commonly caused by exposure to cigarette smoke. Small airway remodelling (SAR) is a key pathological event in COPD affecting mainly the respiratory and membranous bronchioles, resulting in irregularly shaped lumens as well as thickened airway walls. Analyses of human and animal samples has shown that smoke exposure causes increased fibrosis, a feature of SAR; additional experiments have shown upregulation of many growth factors in various pulmonary fibrosis diseases and models. Further research into the pathogenesis of COPD is necessary as current treatments have not been overwhelmingly successful; a better understanding of the pathological processes involved in the development of SAR could lead to new and innovative therapies. This project examined the fibrotic response induced by cigarette smoke in the small airways of mice; laser capture microdisection was used to selectively dissect the airways from the remainder of the lung tissue. Real-time PCR was used to determine the gene expression levels of procollagen and the growth factors TGFβ, CTGF, PDGF-A, and PDGF-B, which have been previously implicated in a number of fibrotic diseases. Following a single smoke exposure a peak in all gene expression levels occurred at 2 hours, which resolved by 6 hours for all growth factors. Procollagen expression levels declined much slower, and at 24 hours the apparent increase in expression was no longer statistically significant due to variability. Repeated smoke exposures resulted in a significant increase in procollagen and all growth factors at 1 week, 1 month, and 6 months, with the exception of TGFβl at 6 months, and PDGF-A at 1 month. These data indicate that chronic exposure of C57B1/6 mice to cigarette smoke does induce a sustained fibrotic response as indicated by the procollagen data, and that several growth factors are important in this response.

description: The main goal of the T2K long-baseline neutrino experiment is the precise measurement of the parameters of neutrino oscillation and the search for CP-violation in the lepton sector. In 2017, the T2K collaboration launched the Near Detector Upgrade project. This upgrade aims to reduce the systematic errors of the oscillation parameters from 6-7% to 3-4%. In order to accomplish such goal, ND280 Upgrade proposes to implement new upstream trackers to improve the wide angle acceptance and low momentum threshold. One of the novel technologies introduced in ND280 Upgrade is super fine-grained (SuperFGD) scintillator target with 3D WLS fiber readout. The detector will consist of about 2 million (192x184x56) scintillation cubes of 1-cm size. Each cube has three orthogonal holes for WLS fibers to provide 3D optical readout. The total mass of the detector is about 2 tons and the number of the readout channels is about 60,000. This paper presents the current status of the development of this detector.
