description: For an integer $w$, let $\cs_w$ be the algebraic triangulated category generated by a $w$-spherical object. We determine the Picard group of $\cs_w$ and show that each orbit category of $\cs_w$ is triangulated and is triangle equivalent to a certain orbit category of the bounded derived category of a standard tube. When $n=2$, the orbit category $\cs_w/Σ^2$ is 2-periodic triangulated, and we characterize the associated Ringel--Hall Lie algebra in the sense of Peng and Xiao.

description: We provide conditions which yield a strong law of large numbers for expressions of the form $1/N\sum_{n=1}^{N}F\big(X(q_1(n)),..., X(q_\ell(n))\big)$ where $X(n),n\geq 0$'s is a sufficiently fast mixing vector process with some moment conditions and stationarity properties, $F$ is a continuous function with polinomial growth and certain regularity properties and $q_i,i>m$ are positive functions taking on integer values on integers with some growth conditions. Applying these results we study certain multifractal formalism type questions concerning Hausdorff dimensions of some sets of numbers with prescribed asymptotic frequencies of combinations of digits at places $q_1(n),...,q_\ell(n)$.

description: A new approach called the Schrödinger Collective Intrinsic Model (SCIM) has been developed to achieve a microscopic description of the coupling between collective and intrinsic excitations. The derivation of the SCIM proceeds in two steps. The first step is based on a generalization of the symmetric moment expansion of the equations derived in the framework of the Generator Coordinate Method (GCM), when both Hartree-Fock-Bogoliubov (HFB) states and two-quasi-particle excitations are taken into account as basis states. The second step consists in reducing the generalized Hill and Wheeler equation to a simpler form to extract a Schrödinger-like equation. The validity of the approach is discussed by means of results obtained for the overlap kernel between HFB states and two-quasi-particle excitations at different deformations.

Markov random fields, Gibbs states and entropy minimality
Creators: name: Chandgotia, Nishant
Publisher: name: University of British Columbia
Year: 2015

description: The well-known Hammersley-Clifford Theorem states (under certain conditions) that any Markov random field is a Gibbs state for a nearest neighbour interaction. Following Petersen and Schmidt we utilise the formalism of cocycles for the homoclinic relation and introduce "Markov cocycles", reparametrisations of Markov specifications. We exploit this formalism to deduce the conclusion of the Hammersley-Clifford Theorem for a family of Markov random fields which are outside the theorem's purview (including Markov random fields whose support is the d-dimensional "3-colored chessboard"). On the other extreme, we construct a family of shift-invariant Markov random fields which are not given by any finite range shift-invariant interaction. The techniques that we use for this problem are further expanded upon to obtain the following results: Given a "four-cycle free" finite undirected graph H without self-loops, consider the corresponding 'vertex' shift, H ơm(Zd,H) denoted by X(H). We prove that X(H) has the pivot property, meaning that for all distinct configurations x,y ∈ X(H) which differ only at finitely many sites there is a sequence of configurations (x=x¹),x²,...,(xn =y) ∈ X(H) for which the successive configurations (xi,xi+1) differ exactly at a single site. Further if H is connected we prove that X(H) is entropy minimal, meaning that every shift space strictly contained in X(H) has strictly smaller entropy. The proofs of these seemingly disparate statements are related by the use of the 'lifts' of the configurations in X(H) to their universal cover and the introduction of 'height functions' in this context. Further we generalise the Hammersley-Clifford theorem with an added condition that the underlying graph is bipartite. Taking inspiration from Brightwell and Winkler we introduce a notion of folding for configuration spaces called strong config-folding to prove that if all Markov random fields supported on X are Gibbs with some nearest neighbour interaction so are Markov random fields supported on the "strong config-folds" and "strong config-unfolds" of X.

description: Gradient index sonic lenses based on two-dimensional sonic crystals are here designed, fabricated and characterized. The index-gradient is achieved in these type of flat lenses by a gradual modification of the sonic crystal filling fraction along the direction perpendicular to the lens axis. The focusing performance is well described by an analytical model based on ray theory as well as by numerical simulations based on the multiple-scattering theory.

description: We determine the intrinsically disordered regions (IDRs) of phase separating proteins and investigate their impact on liquid-liquid phase separation (LLPS) with a random-phase approx- imation (RPA) that accounts for variable salt concentration. We focus on two proteins, PGL-3 and FUS, known to undergo LLPS. For PGL-3 we predict that an IDR near the C-terminus pro- motes LLPS, which we validate through direct comparison with in vitro experimental results. For the structurally more complex protein FUS the role of the low complexity (LC) domain in LLPS is not as well understood. Apart from the LC domain we here identify two IDRs, one near the N-terminus and another near the C-terminus. Our RPA analysis of these domains predict that, surprisingly, the IDR at the N-terminus (aa 1-285) and not the LC domain promotes LLPS of FUS by comparison to in vitro experiments under physiological temperature and salt conditions.

description: Die vorliegende Studie verfolgte das Ziel, die Emotionen von Schüler*innen, deren Kontroll- und Wertkognitionen sowie die wahrgenommene Bedürfnisunterstützung beim Offenen Lernen (COOL: Cooperatives Offenes Lernen) auf Basis der theoretischen Grundannahmen der Selbstbestimmungstheorie und der Kontroll-Wert-Theorie zu untersuchen. Hierzu wurden 97 Gymnasialschüler*innen eines Schulzweigs mit hohem Anteil an COOL sowie eines alternativen Zweigs schriftlich befragt. Die Ergebnisse machen deutlich, dass die Emotionen der Schüler*innen in COOL-Lernumgebungen überwiegend positiver waren als jene der Vergleichsgruppe. Dieses Bild zeigte sich auch für die Selbstwirksamkeit der Schüler*innen als Indikator für die Kontrollkognition und das Interesse als Indikator für die Wertkognition. Zudem zeigte sich erwartungskonform,  dass positive Emotionen und auch Kontroll- und Wertkognitionen durch die wahrgenommene Autonomie- und Kompetenzunterstützung sowie die Unterstützung der sozialen Eingebundenheit im Unterricht erklärt werden können. Implikationen für die Gestaltung emotionsgünstiger Lehr-Lern-Umgebungen werden abgeleitet.
description: The present study aimed to investigate students emotions, control- and value cognitions and the perceived support of their basic psychological needs in Cooperative Open Learning settings (COOL) relying on Self-Determination Theory and Control-Value Theory. Ninety-seven secondary students who attended either Cooperative Open Learning classes or conventional learning classes participated in the study and answered a questionnaire. The results demonstrate that the emotional pattern of students in Cooperative Open Learning classes was more positive than in traditional ones. The same can be said for students self-efficacy (as an indicator of control cognition) and interest (as an indicator of value cognition), which were higher in the COOL classes. Additionally and as expected, the findings showed a significant link between students perceptions in terms of a need-supportive social environment and their positive emotions and control-value cognitions. Implications in order to design emotionally sound learning environments are proposed.

description: We present the N, O, F and Na abundance and 12C/13C isotopic ratio measurements or upper limits for a sample of 10 C-rich, metal-poor giant stars, eight enhanced in s-process (CEMP-s) elements and two poor in n-capture elements (CEMP-no). The abundances are derived from IR, K-band, high-resolution CRIRES@VLT spectra obtained. The metallicity of our sample ranges from [Fe/H]=-3.4 to -1.3. F abundance could be measured only in two CEMP-s stars. With [F/Fe]=0.64, one is mildly F-overabundant, while the other is F-rich, at [F/Fe]=1.44. For the remaining eight objects, including both CEMP-no in our sample, only upper limits on F abundance could be placed. Our measurements and upper limits show that there is a spread in [F/C+N] ratio in CEMP-s stars as predicted by theory. Predictions from nucleosynthetic models for low-mass, low-metallicity Asymptotic Giant Branch stars, account for the derived F abundances, while the upper limits on F content derived for most of the stars are lower than the predicted values. The measured Na content is accounted for by AGB models in the 1.25 to 1.7 Msun range, confirming that the stars responsible for the peculiar abundance pattern observed in CEMP-s stars are low-mass, low-metallicity AGB stars, in agreement with the most accepted astrophysical scenario. We conclude that the mechanism of F production in current state-of-the-art low-metallicity low-mass AGB models needs further scrutiny and that F measurements in a larger number of metal-poor stars are needed to better constraint the models.

description: Present and future ultra-high-energy-cosmic-ray facilities (e.g., the Pierre Auger Observatory with South and North components) and TeV-gamma-ray telescope arrays (e.g., HESS or VERITAS and CTA) have the potential to set stringent indirect bounds on the nine Lorentz-violating parameters of nonbirefringent modified Maxwell theory minimally coupled to standard Dirac theory. Theoretically, the most interesting case is isotropic Lorentz violation, which is described by a single parameter [taken to vanish for the standard Lorentz-invariant theory]. It appears possible to obtain in the future an upper (lower) indirect bound on this single isotropic Lorentz-violating parameter at the +10^{-21} (-10^{-17}) level. Comparison is made with existing and future direct bounds from laboratory experiments. The possible physics implications of upper bounds at the 10^{-21} level are discussed.

Understanding school psychologists' roles in assuring adequate sex education for students with disabilities
Creators: name: Desai, Khyati
Publisher: name: No Publisher Supplied
Year: 2019

description: Due to current sex education practices, students with disabilities (SWDs) are often misinformed about sexual matters, are at higher risk of sexual abuse and unsafe sexual practices, and experience lower life satisfaction in regard to relationships. Despite the need for better and more accessible sex education for SWDs, research on this topic and on the barriers SWDs face is sparse. The ineffective provision of sex education indicates the need for involvement of school psychologists, who may be uniquely prepared to address the gap given their skills and job roles. Thus, the purpose of this study was to explore the potential for a school psychologist role in sex education. School psychologists in New Jersey public schools were surveyed in order to understand their current, potential, and desired roles in sex education for SWDs. A total of 145 participants completed the survey, representing an overall response rate of 10%. Data was analyzed using descriptive statistics, chi square tests to compare observed and expected sample distribution, and thematic analyses of open ended responses. Results of the study indicate only 3% of school psychologists are currently involved in sex education, although 68% of school psychologists report they should be involved. The highest rated methods of involvement for school psychologists in sex education for SWDs were advocating for appropriate education (70%) and consulting on developmentally appropriate activities and instruction (66%). Facilitators to involvement in sex education included existing consultation roles, relationships with SWDs and parents, availability of counseling, and training. Barriers to involvement in sex education included cultural norms, sex education being the responsibility of another staff member, and lack of time, support, and training. Limitations of the study, as well as implications for practice and future research directions, are discussed.

description: In this paper, we build on recent results of Frank Garvan and Rishabh Sarma as well as classical results of Bruce Berndt in order to establish the 11-dissection of the deviations of the rank and crank modulo 11. Using our new dissections we re-derive results of Garvan, Atkin, Swinnerton-Dyer, Hussain and Ekin. By developing and exploiting positivity conditions for quotients of theta functions, we will also prove new rank-crank inequalities and make several conjectures. For other applications of our methods, we will prove new congruences for rank moments as well as the Andrews' smallest parts function and Eisenstein series.

description: Background: Prior research mainly focussed on the impact of the teacher-student relationship on teachers emotions and wellbeing. Current data shows a relationship between the quality of the teacher-student relationship and children’s mental health. Unfortunately, it has not yet been investigated whether meaningful experiences with teachers also have an impact on students’ well-being and whether an effect can still be found in adulthood. This work examines the impact of meaningful experiences with teachers during childhood and adolescence on the well-being of adults. Methods: The data in this study was collected by using a questionnaire. The current well-being of the participants was assessed with measures of life satisfaction, resilience, anxiety, stress, depressiveness, and self-esteem. Also, participants were asked to briefly write about their most meaningful experiences with teachers and rate them regarding their valence. These experiences were categorized into seven categories using a summarizing content analysis. We then conducted a statistical analysis with the data obtained. Results: The results showed a highly significant correlation between the participants’ self-esteem and the valence ratings of their experiences. Furthermore, the experience category had a substantial effect on individual self-esteem. Overall, this study demonstrated that a relationship exists between the well-being of adults and their experiences with teachers during childhood and adolescence. Conclusion: The results of this study call for a reflective, fair, authentic, and empathetic approach to students. Accordingly, teachers should be intensively trained to establish a relationship with their students that is characterized by appreciation and empathy.

description: The coupled dynamics of low lying modes, including the scissors mode, and various giant quadrupole resonances are studied with the help of the Wigner Function Moments method generalized to take into account spin degrees of freedom. Equations of motion for collective variables are derived on the basis of Time Dependent Hartree-Fock equations in the model of harmonic oscillator with spin orbital mean field potential plus quadrupole-quadrupole residual interaction. Introducing spin allows one to consider new types of nuclear collective motion where the nucleons with spin 'up' oscillate against nucleons with spin 'down'.

description: We have surveyed $\sim40$sq.degrees surrounding M33 with CFHT MegaCam in the g and i filters, as part of the Pan-Andromeda Archaeological Survey. Our observations are deep enough to resolve the top 4mags of the red giant branch population in this galaxy. We have previously shown that the disk of M33 is surrounded by a large, irregular, low-surface brightness substructure. Here, we quantify the stellar populations and structure of this feature using the PAndAS data. We show that the stellar populations of this feature are consistent with an old population with $\sim-1.6$dex and an interquartile range in metallicity of $\sim0.5$dex. We construct a surface brightness map of M33 that traces this feature to $μ_V\simeq33$mags\,arcsec$^{-2}$. At these low surface brightness levels, the structure extends to projected radii of $\sim40$kpc from the center of M33 in both the north-west and south-east quadrants of the galaxy. Overall, the structure has an "S-shaped" appearance that broadly aligns with the orientation of the HI disk warp. We calculate a lower limit to the integrated luminosity of the structure of $-12.7\pm0.5$mags, comparable to a bright dwarf galaxy such as Fornax or AndII and slightly less than $1\$ of the total luminosity of M33. Further, we show that there is tentative evidence for a distortion in the distribution of young stars near the edge of the HI disk that occurs at similar azimuth to the warp in HI. The data also hint at a low-level, extended stellar component at larger radius that may be a M33 halo component. We revisit studies of M33 and its stellar populations in light of these new results, and we discuss possible formation scenarios for the vast stellar structure. Our favored model is that of the tidal disruption of M33 in its orbit around M31.

description: In this letter we not only show improvement in the performance but also in the reliability of 30nm thick biaxially strained SiGe (20%Ge) channel on Si p-MOSFETs. Compared to Si channel, strained SiGe channel allows larger hole mobility (μh) in the transport direction and alleviates charge flow towards the gate oxide. μh enhancement by 40% in SiGe and 100% in Si-cap SiGe is observed compared to the Si hole universal mobility. A ~40% reduction in NBTI degradation, gate leakage and flicker noise (1/f) is observed which is attributed to a 4% increase in the hole-oxide barrier height (ϕ) in SiGe. Similar field acceleration factor (Γ) for threshold voltage shift (ΔVT) and increase in noise (ΔSVG) in Si and SiGe suggests identical degradation mechanisms.

The Effect of Gravitational Tidal Forces on Vacuum Polarization: How to Undress a Photon

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The effect of gravitational tidal forces on photon propagation in curved spacetime is investigated. It is found that the imaginary part of the local refractive index Im n(u;w) may be negative as well as positive, corresponding to a local amplification as well as attenuation of the amplitude of the renormalized photon field. This is interpreted in terms of the effect of tidal forces on the virtual e^+e^- cloud surrounding the bare photon field---a positive/negative Im n(u;w) corresponds to an increased dressing/undressing of the bare photon. Below threshold decays of the photon to e^+e^- pairs can occur. Photon undressing in the vicinity of a black hole singularity is described as an example. These results are shown to be consistent with unitarity and the optical theorem in curved spacetime, which is derived here both in a local form and integrated over the photon trajectory.

description: The current state of quantum computing is commonly described as the Noisy Intermediate-Scale Quantum era. Available computers contain a few dozens of qubits and can perform a few dozens of operations before the inevitable noise erases all information encoded in the calculation. Even if the technology advances fast within the next years, any use of quantum computers will be limited to short and simple tasks, serving as subroutines of more complex classical procedures. Even for these applications the resource efficiency, measured in the number of quantum computer runs, will be a key parameter. Here we suggest a general optimization procedure for hybrid quantum-classical algorithms that allows finding the optimal approach with limited quantum resources. We demonstrate this procedure on a specific example of variational quantum algorithm used to find the ground state energy of a hydrogen molecule.

description: Four close radio sources in the International Celestial Reference Frame (ICRF) catalog were observed using phase referencing with the VLBA at 43, 23 and 8.6 GHz, and with VERA at 23 GHz over a one year period. The goal was to determine the stability of the radio cores, and to assess structure effects associated with positions in the ICRF. Although the four sources were compact at 8.6 GHz, the VLBA images at 43 GHz with 0.3-mas resolution showed that all were composed of several components. A component in each source was identified as the radio core using some or all of the following emission properties: compactness, spectral index, location at the end of the extended emission region, and stationary in the sky. Over the observing period, the relative positions between the four radio cores were constant to 0.02 mas---the phase referencing positional accuracy obtained at 23 and 43 GHz among the sources---suggesting that once a radio core is identified, it remains stationary in the sky to this accuracy. Other radio components in two of the four sources had detectable motion in the radio jet direction. Comparison of the 23 and 43 GHz VLBA images with the VLBA 8.6 GHz images and the ICRF positions suggests that some ICRF positions are dominated by a moving jet component; hence, they can be displaced up to 0.5 mas from the radio core, and may also reflect the motion of the jet component. Future astrometric efforts to determine a more accurate quasar reference frame at 23 and 43 GHz and from the VLBI2010 project are discussed, and supporting VLBA or EVN observations of ICRF sources at 43 GHz are recommended in order to determine the internal structure of the sources. A future collaboration between the radio (ICRF) and the optical frame of Gaia is discussed.

Functional studies of PPP2R2A in breast cancer
Creators: name: Ma, Qianli
Publisher: name: University of British Columbia
Year: 2015

description: PPP2R2A is a regulatory subunit of protein phosphatase 2A (PP2A). Genomic analysis based on 2000 breast cancer cases identified PPP2R2A as one of the deletion hotspots in breast cancer genomes and 63% of PPP2R2A deletions were found in estrogen receptor positive (ER+) breast cancers. We hypothesized that the high frequency deletion of PPP2R2A, as well as its correlation with ER expression status, implies its functional roles in breast cancer development. In this thesis, I investigated the functional impacts of PPP2R2A deletion in breast cancer development from the aspects of ER signaling, PP2A complex composition, and cell morphological changes. First, I studied ER signaling activity and mechanism in T47D cells with the analysis of transcriptome, ER binding specificity and ER co-factor recruitment, etc. Second, I studied PP2A complex composition in three breast cell models with targeted quantitative mass spectrometry (MRM). Last, I studied morphological changes in mammary breast cell models, 184-hTERT and MCF10A, in terms of cell proliferation, surface protein localization, and cell mobility based on transcriptome and signaling network analysis. As a result, reduced expression of PPP2R2A led to differential expression of ER response genes, alterations in ER binding specificity, and changes in ER co-factor composition. SPDEF was particularly up regulated and recruited in ER transcriptional machinery. Analysis in clinical samples also confirmed the correlation of SPDEF up regulation with ER expression status and PPP2R2A copy number loss. In addition, MRM analysis revealed changes in PP2A complex composition after PPP2R2A knockdown with increased relative abundance of STRN in PP2A complexes in ER positive cell models. Finally, my morphological studies demonstrated mislocalization of cell surface proteins and enhanced cell mobility in breast mammary epithelial cell models with reduced PPP2R2A expression. In conclusion, PPP2R2A plays an important role in regulating cell signaling activity and cellular morphology and its genomic deletion would significantly contribute to the development of breast cancer.

description: In the framework of the one-boson-exchange model, we have studied the interaction of the $B^*\bar{B}$ and $B^*\bar{B}^{*}$ system. After considering the S-wave and D-wave mixing, we notice that both $Z_b(10610)^\pm$ and $Z_b(10650)^\pm$ can be interpreted as the $B^*\bar{B}$ and $B^*\bar{B}^{*}$ molecular states quite naturally. Within the same framework, there also exist several molecular charmonia including X(3872) and several other molecular bottomonia, which are the partners of $Z_b(10610)$ and $Z_b(10650)$. The long-range one-pion-exchange force alone is strong enough to form these loosely bound molecular states, which ensures the numerical results quite model-independent and robust.

description: In this talk we review some recent results on the infrared properties of the gluon and ghost propagators in pure Yang-Mills theories. These results are obtained from the corresponding Schwinger-Dyson equation formulated in a special truncation scheme, which preserves gauge invariance. The presence of massless poles in the three gluon vertex triggers the generation of a dynamical gluon mass (Schwinger mechanism in d=4), which gives rise to an infrared finite gluon propagator and ghost dressing function. As a byproduct of this analysis we calculate the Kugo-Ojima function, required for the definition of the non-perturbative QCD effective charge within the pinch technique framework. We show that the numerical solutions of these non-perturbative equations are in very good agreement with the results of SU(3) lattice simulations.

description: Es ist weiterhin wenig darüber bekannt, inwiefern Maßnahmen der Inneren Differenzierung (ID) im Unterricht mit affektiv-motivationalen Aspekten des Lernens von Schüler*innen einhergehen. Dieser Beitrag geht der Frage nach, wie „arrangierte“ und „anlassbezogene“ Maßnahmen der Inneren Differenzierung im MINT-Unterricht die Qualität der Lernmotivation erklären können. Zudem wird untersucht, ob die Unterstützung der grundlegenden psychologischen Bedürfnisse (Basic Needs) nach Autonomie, Kompetenz und sozialer Einbindung, die nach der Selbstbestimmungstheorie (SDT; Ryan & Deci, 2017) grundlegend für die autonome Motivation sind, den Zusammenhang zwischen ID und Lernmotivation mediieren. Die Stichprobe umfasst 1 320 Schüler*innen der Sekundarstufe I und II, die über ihren Unterricht und ihr Erleben in einem MINT-Fach berichteten. Die Ergebnisse von Strukturgleichungsmodellen veranschaulichen, dass die wahrgenommene anlassbezogene ID höher mit der autonomen Lernmotivation korreliert, als dies bei arrangierten ID der Fall ist. Arrangierte Maßnahmen der ID sind zudem mit kontrollierter Lernmotivation assoziiert. Die Basic Needs mediieren den Zusammenhang zwischen ID und introjizierter, identifizierter und intrinsischer Regulation beim Lernen substanziell.
description: Little is still known about the extent to which measures of differentiated instruction in the classroom are associated with affective-motivational aspects of student learning. This paper explores how "arranged" and "occasion-based" measures of differentiated instruction in STEM instruction can explain the quality of learning motivation. In addition, it examines whether support for basic psychological needs for autonomy, competence, and social relatedness, which are fundamental to autonomous motivation according to Self-Determination Theory (SDT; Ryan & Deci, 2017), mediate the relationship between differentiated instruction and learning motivation. The sample includes 1 320 junior and senior high school students who reported on their learning and experience in a STEM subject. Structural equation model results demonstrate that perceived occasion-based differentiated instruction correlates higher with autonomous learning motivation than does arranged differentiated instruction. Arranged measures of differentiated instruction are also associated with controlled learning motivation. Basic needs substantially mediate the relationship between differentiated instruction and introjected, identified and intrinsic regulation.

description: 3D excitation-emission luminescence spectra of Bi-doped optical fibers of various compositions were measured in a wide wavelength range 450-1700 nm. Such luminescence spectra were obtained for Bi-doped pure silica and germania fibers, and for Bi-doped Al- or P-codoped silica fibers (at room and liquid nitrogen temperatures). The energy level schemes of IR bismuth active centers in pure silica and germania core fibers were derived from spectra obtained. The energy level schemes similarity of bismuth active centers in these two types of fibers was revealed.

X-ray observational signature of a black hole accretion disc in an active galactic nucleus RXJ1633+4718

description: We report the discovery of a luminous ultra-soft X-ray excess in a radio-loud narrow-line Seyfert1 galaxy, RXJ1633+4718, from archival ROSAT observations. The thermal temperature of this emission, when fitted with a blackbody, is as low as 32.5(+8.0,-6.0)eV. This is in remarkable contrast to the canonical temperatures of ~0.1-0.2keV found hitherto for the soft X-ray excess in active galactic nuclei (AGN), and is interestingly close to the maximum temperature predicted for a postulated accretion disc in this object. If this emission is indeed blackbody in nature, the derived luminosity [3.5(+3.3,-1.5)x10^(44)ergs/s] infers a compact emitting area with a size [~5x10^(12)cm or 0.33AU in radius] that is comparable to several times the Schwarzschild radius of a black hole at the mass estimated for this AGN (3x10^6Msun). In fact, this ultra-steep X-ray emission can be well fitted as the (Compton scattered) Wien tail of the multi-temperature blackbody emission from an optically thick accretion disc, whose parameters inferred (black hole mass and accretion rate) are in good agreement with independent estimates using optical emission line spectrum. We thus consider this feature as a signature of the long-sought X-ray radiation directly from a disc around a super-massive black hole, presenting observational evidence for a black hole accretion disc in AGN. Future observations with better data quality, together with improved independent measurements of the black hole mass, may constrain the spin of the black hole.

description: The local distribution of exciton levels in disordered cyanine-dye-based molecular nano-aggregates has been elucidated using fluorescence line narrowing spectroscopy. The observation of a Wigner-Dyson-type level spacing distribution provides direct evidence of the existence of level repulsion of strongly overlapping states in the molecular wires, which is important for the understanding of the level statistics, and therefore the `functional properties, of a large variety of nano-confined systems.

description: Despite its importance in determining coping behaviors, few studies have assessed the reality of chronic obstructive pulmonary disease (COPD) and its management perceived by patients. This study aimed at an in-depth understanding of this reality to identify COPD patients’ attitudes, COPD-shaped experiences, and overlooked needs during their journey. Qualitative ethnographic study including 28 adult patients with moderate and severe COPD and 20 healthcare professionals. Study phases were (1) in-depth individual and (2) ethnographic interviews (qualitative), and (3) online questionnaires (quantitative), including 400 patients. Qualitative data were collected using audio, video, and observation notes. Three ethnographers analyzed data using a template covering different themes: attitudes of COPD patients, COPD-shaped experiences, and overlooked needs. We identified four attitudinal profiles of COPD patients: ‘active controller,’ ‘naïve minimizer,’ ‘defeated sufferer,’ and ‘struggling bon vivant,’ which were validated in 400 COPD patients, as well as five stages in the COPD patient journey and overlookedneeds. The ‘active controller’ profile was associated with slower disease progression compared with the ‘defeated sufferer’ and ‘struggling bon vivant’ profiles. Four attitudinal profiles were distinguished and validated in a large sample of COPD patients. Patients’ attitudes impacted in COPD-associated experiences, limitations, and unmet needs, which differed among profiles.
