description: Background: Patients diagnosed with an autoimmune disease are often systemically medicated with glucocorticoids. Autoimmune pancreatitis (AIP) Type 1 is considered a rare autoimmune disease, which is very well responsive to glucocorticoids and hence can be treated optionally on a long-term basis using low dose of the drug. Apical lesions of root canal-treated teeth can be solved by retreatment of the preexisting root canal obturation or via surgical approaches. Case presentation: This case report relates to a 76-year-old male patient, whose symptomatic acute apical periodontitis was treated nonsurgically by root canal treatment. However, overtime both roots of tooth 46 were associated with asymptomatic apical lesions. Despite progression of the lesions, due to a painless situation, the patient refrained from proceeding with any further treatment options after explaining the pathological pathway with all its consequences. A few years later the patient was prescribed 2.5 mg glucocorticoid prednisone daily for long-term therapy due to an AIP Type 1. Six years later under strict glucocorticoid therapy the apical lesions healed nearly completely and the patient remained free of symptoms without any further interventions. Conclusions: These observations suggest that prospective clinical studies are required to further elucidate the potential healing effect of systemic long-term low-dose glucocorticoid medication on lesions of endodontic origin.

description: We consider XY-spin degrees of freedom on an FCC lattice, such that the system respects some subsystem global symmetry. We then gauge this global symmetry and study the corresponding $U(1)$ gauge theory on the FCC lattice. Surprisingly, this $U(1)$ gauge theory is dual to the original spin system. We also analyze a similar $\mathbb{Z}_N$ gauge theory on that lattice. All these systems are fractonic. The $U(1)$ theories are gapless and the $\mathbb{Z}_N$ theories are gapped. We analyze the continuum limits of all these systems and present free continuum Lagrangians for their low-energy physics. Our $\mathbb{Z}_2$ FCC gauge theory is the continuum limit of the well known checkerboard model of fractons. Our continuum analysis leads to a straightforward proof of the known fact that this theory is dual to two copies of the $\mathbb{Z}_2$ X-cube model. We find new models and new relations between known models. The $\mathbb{Z}_N$ FCC gauge theory can be realized by coupling three copies of an anisotropic model of lineons and planons to a certain exotic $\mathbb{Z}_2$ gauge theory. Also, although for $N=2$ this model is dual to two copies of the $\mathbb{Z}_2$ X-cube model, a similar statement is not true for higher $N$.

description: This paper explores disability rights activism as a form of collective political participation. This type of organised civil society has been and continues to be vital in promoting and implementing social and political change in European societies. However, little is known about its structures and resources, activities and effects. First, this paper discusses different typologies of disability rights activism and proposes an own attempt of systematising different forms of disability rights activism. By comparing various, rationalist as well as constructivist, theoretical approaches, this article develops an integrated framework for analysing disability organisations by drawing on approaches that consider the interrelations between structure and agency. Second, applying new social movement theory, we explore identity politics and models of disability as identity frames of disability rights activism. Both aspects relate to the pivotal question of how the interests of persons with disabilities are represented in disability politics. Finally, based on documentary analysis of primary data and structured national reports findings of a comparative analysis from a sample of nine European countries (Czech Republic, Germany, Italy, Ireland, Norway, Serbia, Sweden, Switzerland, United Kingdom) are offered. There is evidence that the principle of self-representation—which is a crucial demand of the disability rights movement—has resulted in different practices at the level of national disability assemblies.

Governing Madness – Transforming Psychiatry Disability History and the Formation of Cultural Knowledge in West Germany in the 1970s and 1980s
Creators: name: Klein, Anne
Publisher: name: Moving the Social
Year: 2015

description: In 1975, the German Bundestag published the Psychiatrie-Enquête, a 1,800 pages report, which had been produced over five years by more than 200 experts under the auspices of Aktion psychisch Kranke e.V. The reform movement, which throughout the following 20 years established institutional standards of social psychiatry in the Federal Republic of Germany (FRG), was strongly influenced by the principles of welfare politics implemented in the states of Northern Europe. However, some minor trajectories of knowledge can be detected and will be discussed in this article. On the level of therapeutic and anthropological thinking, the ongoing and fierce critique of institutionalised psychiatric exclusion in different European countries was accompanied by new arguments of social research and critical theory. On the level of historical awareness, the emerging knowledge of the Nazi genocide and euthanasia led to a memory turn in 1979. Historical research on the so-called forgotten victims supported the acknowledgement and emancipation of psychiatric patients during the 1980s, which could be realised under the new social psychiatry frame. On the level of democratisation, patients’ self-help and -advocacy as well as their networks of support established a strong voice in the public, which since then has to be heard in political decision-making. These three trajectories of (marginalised) knowledge strongly affected cultural democratisation as the necessary platform or general heaven for moving social institutions and political realities. The aim of this paper is to get a clearer image of their conceptual influences on Western Germany’s intellectual and political consciousness in moving social imagination and the democratisation of interactions. The study will work with the de/constructionist cultural approach to disability in order to expound the problems of knowledge discourses and their effects on the constructions of normativity and inequality.

description: In this paper we study the concept of the boost mass of a spacetime and investigate how variations in the boost mass enter into the laws of black hole mechanics. We define the boost mass as the gravitational charge associated with an asymptotic boost symmetry, similiar to how the ADM mass is associated with an asymptotic time translation symmetry. In distinction to the ADM mass, the boost mass is a relevant concept when the spacetime has stress energy at infinity, and so the spacetime is not asymptotically flat. We prove a version of the first law which relates the variation in the boost mass to the change in the area of the black hole horizon, plus the change in the area of an acceleration horizon, which is necessarily present with the boost Killing field, as we discuss. The C-metric and Ernst metric are two known analytical solutions to Einstein-Maxwell theory describing accelerating black holes which illustrate these concepts.

description: Quantum nonlocality, one of the most important features of quantum mechanics, is normally connected in experiments with the violation of Bell-Clauser-Horne (Bell-CH) inequalities. We propose effective methods for the rearrangement and linear inequality to prove a large variety of Bell-CH inequalities. We also derive a set of Bell-CH inequalities by using these methods which can be violated in some quantum entangled states.

description: An overwhelming fraction of photons from relativistic heavy ion collisions has its origin in the decay of $π^0$ and $η$ mesons. We calculate the azimuthal asymmetry of the decay photons for several azimuthally asymmetric pion distributions. We find that the $k_T$ dependence of the elliptic flow parameter$v_2$ for the decay photons closely follows the elliptic flow parameter $v_2^{π^0}$ evaluated at $p_T \approx k_T+δ$, where $δ\approx$ 0.1 -- 0.2 GeV, for typical pion distributions measured in nucleus-nucleus collisions at relativistic energies. Similar results are obtained for photons from the 2-$γ$ decay of $η$ mesons. Assuming that the flow of $π^0$ is similar to those for $π^+$ and $π^-$ for which independent measurements would be generally available, this ansatz can help in identifying additional sources for photons. Taken along with quark number scaling suggested by the recombination model, it may help to estimate $v_2$ of the parton distributions in terms of azimuthal asymmetry of the decay photons at large $k_T$.

Disability Movements National Policies and Transnational Perspectives – Introductory Remarks
Creators: name: Stoll, Jan
Publisher: name: Moving the Social
Year: 2015

description: The special issue Disability Movements: National Policies and Transnational Perspectives examines different Disability Movements and their transnational entanglements in the 20th century. The articles in this issue enquire into the adaptions and transfers between different national movements and into the establishment of networks across borders nbetween like-minded people, who shared similar aims. Furthermore, they ask about nprocesses of how knowledge and strategies were transferred, exchanged and adapted. Therefore, the issue combines three different research strands: First, disability; second, new social movement research; and third, transnational approaches. The adoption of the United Nations Convention of the Rights of Persons with Disabilities in 2006 highlights the need of considering disability rights activism on national as well as international levels.

Eccentric Tidal Disruption Event Disks around Supermassive Black Holes: Dynamics and Thermal Emission

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: After the Tidal Disruption Event (TDE) of a star around a SuperMassive Black Hole (SMBH), if the stellar debris stream rapidly circularizes and forms a compact disk, the TDE emission is expected to peak in the soft X-ray or far Ultra-Violet (UV). The fact that many TDE candidates are observed to peak in the near UV and optical has challenged conventional TDE emission models. By idealizing a disk as a nested sequence of elliptical orbits which communicate adiabatically via pressure forces, and are heated by energy dissipated during the circularization of the nearly parabolic debris streams, we investigate the dynamics and thermal emission of highly eccentric TDE disks, including the effect of General-Relativistic apsidal precession from the SMBH. We calculate the properties of uniformly precessing, apsidally aligned, and highly eccentric TDE disks, and find highly eccentric disk solutions exist for realistic TDE properties (SMBH and stellar mass, periapsis distance, etc.). Taking into account compressional heating (cooling) near periapsis (apoapsis), we find our idealized eccentric disk model can produce emission consistent with the X-ray and UV/Optical luminosities of many optically bright TDE candidates. Our work attempts to quantify the thermal emission expected from the shock-heating model for TDE emission, and finds stream-stream collisions are a promising way to power optically bright TDEs.

A Blind Spot of a Guiding Country? Human Rights and Dutch Disability Groups Since 1981
Creators: name: Trigt, Paul Van
Publisher: name: Moving the Social
Year: 2015

description: This article investigates how and why the framework of human rights was (not) used by two important Dutch cross-disability organisations, the Dutch Council of People with Disability and the Dutch department of Independent Living, since the International United Nations Year of Disabled Persons (1981) until now. As in other countries the word human is added to give the fight for equal civil rights by disability activists more power. In striving for civil rights and equal citizenship, Dutch disability activists were in particular inspired by the disability rights movement in the United States (US). At the beginning of the 1990s the Dutch disability activists hoped to realise equal citizenship as was achieved with the Americans with Disabilities Act and to play a role as guiding country in Europe. When disability was not added to Dutch non-discrimination legislation in 1994, a narrative of “lagging behind” with regard to disability policies came into being. This narrative inspires Dutch disability activists until today. In their struggle for equal citizenship it became increasingly common to refer to human rights. In referring to rights, the Dutch were relatively late in comparison to other Western countries and this can be explained by a combination of Dutch particularities.

Refashioning Women’s Self and Mining Homemakers and Producers on the South African Mines, 1976 – 2011
Creators: name: Nite, Dhiraj Kumar
Publisher: name: Moving the Social
Year: 2015

description: This article explores the specific ways women performed conflicting gender identities at home and when engaged in waged work in South African mines, as compared to other global cases. They fought back the belittling disreputable image of the urban working-class women and yet refused to be identified merely as acceptable housewives or mute witnesses of family disintegration. They negotiated claims for jobs, strove to salvage marriages and objected to domestic abuse. A woman compensated for marriage failure through initiating a new family structure consisting of her children, niece, nephew and / or other street children, and grooming them to achieve social advancement. Women took up the challenge of proving wrong the racist and sexist stereotypes made against them. They expressed dexterity and handiness, and occasionally, exerted themselves like men. Equally, they sought desexualisation of work relations, and qualified this pursuit with their association with “workerist” integrity and a negotiable, moralising approach to the sexual bully. They challenged the union movement on questions of dignity, propriety and representation of women. Their manner of all these negotiations could not be understood simply as a coping strategy or adaptive pattern. It expressed and, equally, added to the new African tradition of a “motherist” movement (after Gasa 2007), the union movement’s criticism of domestic servitude (after Iris Berger and Pat Gibbs 2007), the intersection of race, gender and apartheid (after Luli Callinicos 2007), and women’s rational consideration and action. A quantum of success in achieving a women-friendly work environment is discernible in the women’s life-histories, which are our primary sources.

The design and synthesis of vanadyl-biguanide complexes as potential synergistic insulin mimics
Creators: name: Woo, Lenny Chick Ying
Publisher: name: University of British Columbia
Year: 2009

description: The coordination of biguanides, specifically biguanide, metformin, and phenformin, to oxovanadium(IV) was designed to function as a potentially synergistic approach towards insulin-mimetic compounds. Biguanides, most importantly metformin, are oral hypoglycemic agents used today to treat type II diabetes mellitus, and vanadium has well documented blood glucose-lowering properties in vivo. Highly coloured, air stable bis(biguanidato)oxovanadium(IV), [VO(big)₂], bis(N¹, N¹-dimethylbiguanidato)oxovanadium(IV), [VO(met)₂], and bis(β-phenethylbiguanidato) oxovanadium(IV), [VO(phenf)₂], were prepared. Solvation with dimethylsulfoxide occurred with VO(big)₂ and VO(met)₂ to form new six-coordinate complexes. Tris(pphenethylbiguanidato) chromium(III) was also synthesized as a possible bifunctional complex because chromium is thought to be responsible for maintaining glucose tolerance. The prepared ligand precursors and complexes were characterized by infrared spectroscopy, mass spectrometry, elemental analyses, magnetic susceptibility, and, where appropriate, 'H NMR spectroscopy. Due to the limited solubilities of these oxovanadium complexes, crystals suitable for X-ray diffraction studies were not obtained. Square pyramidal and octahedral geometries are predicted for the vanadyl-biguanide complexes and the chromium-phenformin complex, respectively. STZ-diabetic rat studies with VO(met)₂, administered by intraperitoneal injection or oral gavage, resulted in ambiguous findings as summarized in Appendix A. The complex VO(met)2 did not demonstrate a synergistic mechanism of action in lowering blood plasma glucose at doses of 0.12 mmol kg⁻¹ and 0.6 mmol kg⁻¹; however, the complex was effective most likely from the vanadium contribution alone.

The Cosmic Near Infrared Background: Remnant Light from Early Stars

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The redshifted ultraviolet light from early stars at z ~ 10 contributes to the cosmic near infrared background. We present detailed calculations of its spectrum with various assumptions about metallicity and mass spectrum of early stars. We show that if the near infrared background has a stellar origin, metal-free stars are not the only explanation of the excess near infrared background; stars with metals (e.g. Z=1/50 Z_sun) can produce the same amount of background intensity as the metal-free stars. We quantitatively show that the predicted average intensity at 1-2 microns is essentially determined by the efficiency of nuclear burning in stars, which is not very sensitive to metallicity. We predict νI_ν/ \dotρ_* ~ 4-8 nW m^-2 sr^-1, where \dot{ρ_*} is the mean star formation rate at z=7-15 (in units of M_sun yr^-1 Mpc^-3) for stars more massive than 5 M_sun. On the other hand, since we have very little knowledge about the form of mass spectrum of early stars, uncertainty in the average intensity due to the mass spectrum could be large. An accurate determination of the near infrared background allows us to probe formation history of early stars, which is difficult to constrain by other means. While the star formation rate at z=7-15 inferred from the current data is significantly higher than the local rate at z<5, it does not rule out the stellar origin of the cosmic near infrared background. In addition, we show that a reasonable initial mass function, coupled with this star formation rate, does not over-produce metals in the universe in most cases, and may produce as little as less than 1 % of the metals observed in the universe today.

description: We study the principal core g-mode oscillation in hybrid stars containing quark matter and find that they have an unusually large frequency range ($\approx$ 200 - 600 Hz) compared to ordinary neutron stars or self-bound quark stars of the same mass. Theoretical arguments and numerical calculations that trace this effect to the difference in the behaviour of the equilibrium and adiabatic sound speeds in the mixed phase of quarks and nucleons are provided. We propose that the sensitivity of core g-mode oscillations to non-nucleonic matter in neutron stars could be due to the presence of a mixed quark-nucleon phase. Based on our analysis, we conclude that for binary mergers where one or both components may be a hybrid star, the fraction of tidal energy pumped into resonant g-modes in hybrid stars can exceed that of a normal neutron star by a factor of 2-3, although resonance occurs during the last stages of inspiral. A self-bound star, on the other hand, has a much weaker tidal overlap with the g-mode. The cumulative tidal phase error in hybrid stars, $Δϕ\cong$ 0.5 rad, is comparable to that from tides in ordinary neutron stars, presenting a challenge in distinguishing between the two cases. However, should the principal g-mode be excited to sufficient amplitude for detection in a post-merger remnant with quark matter in its interior, its frequency would be a possible indication for the existence of non-nucleonic matter in neutron stars.

description: The dissipative and decoherence properties of the two-level atom interacting with the squeezed vacuum field reservoir are investigated based on the nonautonomous master equation of the atomic density matrix in the framework of algebraic dynamics. The nonautonomous master equation is converted into a Schrödinger-like equations and its dynamical symmetry is found based on the left and right representations of the relevant algebra. The time-dependent solution and the steady solution are obtained analytically. The asymptotic behavior of the solution is examined and the approach to the equilibrium state is proved. Based on the analytic solution the response of the system to the squeezed vacuum field reservoir is studied numerically.

description: Quantum theory of the intraband resonant tunneling of a Bose-Einstein condensate loaded in a twodimensional optical lattice is considered. It is shown that the phenomena of quantum collapse and revival can be observed in the fully quantum problem. The mean-field limit of the theory is analyzed using the WKB approximation for discrete equations, establishing in this way a direct connection between the two approaches conventionally used in very different physical contexts. More specifically we show that there exist two different regimes of tunneling and study dependence of quantum collapse and revival on the number of condensed atoms.

Uniform shear flow in dissipative gases. Computer simulations of inelastic hard spheres and (frictional) elastic hard spheres

description: In the preceding paper (cond-mat/0405252), we have conjectured that the main transport properties of a dilute gas of inelastic hard spheres (IHS) can be satisfactorily captured by an equivalent gas of elastic hard spheres (EHS), provided that the latter are under the action of an effective drag force and their collision rate is reduced by a factor $(1+α)/2$ (where $α$ is the constant coefficient of normal restitution). In this paper we test the above expectation in a paradigmatic nonequilibrium state, namely the simple or uniform shear flow, by performing Monte Carlo computer simulations of the Boltzmann equation for both classes of dissipative gases with a dissipation range $0.5\leq α\leq 0.95$ and two values of the imposed shear rate $a$. The distortion of the steady-state velocity distribution from the local equilibrium state is measured by the shear stress, the normal stress differences, the cooling rate, the fourth and sixth cumulants, and the shape of the distribution itself. In particular, the simulation results seem to be consistent with an exponential overpopulation of the high-velocity tail. The EHS results are in general hardly distinguishable from the IHS ones if $α\gtrsim 0.7$, so that the distinct signature of the IHS gas (higher anisotropy and overpopulation) only manifests itself at relatively high dissipations

description: We study dynamical tunneling in a near-integrable Hamiltonian with three degrees of freedom. The model Hamiltonian does not have any discrete symmetry. Despite this lack of symmetry we show that the mixing of near-degenerate quantum states is due to dynamical tunneling mediated by the nonlinear resonances in the classical phase space. Identifying the key resonances allows us to suppress the dynamical tunneling via the addition of weak counter-resonant terms.

description: Exact formulas relating the radii of the spherical photon orbits to the black hole's rotation parameter and the effective inclination angle of the orbit have been known only for equatorial and polar orbits up to now. Here we provide exact formulas for nonequatorial orbits that lie between these extreme limits. For a given rotation parameter of the black hole, there is a critical inclination angle below which there are four null photon orbits two of which are in the exterior region. At the critical angle, the radii of these orbits are explicitly found. We also provide approximate but very accurate formulas for any orbit. To arrive at these analytical solutions, we carefully study the sextic polynomial in the radius that arises for null spherical geodesics.

description: Using data from SDSS, UKIDSS and WISE, we investigate the properties of the high-frequency cutoff to the infrared emission in $\simeq$5000 carefully selected luminous ($L_{bol} \simeq 10^{47}$) type 1 quasars. The strength of $\simeq$2 $μ$m emission, corresponding to emission from the hottest (T>1200K) dust in the sublimation zone surrounding the central continuum source, is observed to correlate with the blueshift of the C IV $λ$1550 emission line. We therefore find that objects with stronger signatures of nuclear outflows tend to have a larger covering fraction of sublimation-temperature dust. When controlling for the observed outflow strength, the hot dust covering fraction does not vary significantly across our sample as a function of luminosity, black hole mass or Eddington fraction. The correlation between the hot dust and the C IV line blueshifts, together with the lack of correlation between the hot dust and other parameters, therefore provides evidence of a link between the properties of the broad emission line region and the infrared-emitting dusty regions in quasars.

description: we experimentally implement a fault-tolerant quantum key distribution protocol with two photons in a decoherence-free subspace (DFS). It is demonstrated that our protocol can yield good key rate even with large bit-flip error rate caused by collective rotation, while the usual realization of BB84 protocol cannot produce any secure final key given the same channel. Since the experiment is performed in polarization space and does not need the calibration of reference frame, important applications in free-space quantum communication are expected. Moreover, our method can also be used to robustly transmit an arbitrary two-level quantum state in a type of DFS.

UHE Leptons and Neutrons feeding Precessing gamma Jet in GRBs - SGRs: A SGR 1806-20 link to EeV C.R.?

description: Soft Gamma Repeaters are widely believed to occur as isotropic Magnetar explosion. We suggest on the contrary that they may be described by thin collimated spinning and precessing Gamma Jets flashing and blazing along the line of sight. The Jet (for SGRs) maybe powered by an accretion disk in binary system and it reproduces huge outflow and oscillating blazing mode as the observed ones in Giant Flare SGR 1806-20. The precessing and spinning blazing nature reflects at smaller intensity the same behavior observed in brief GRBs Jetted Supernova, as well as re-brightening and bumps in afterglows. The SGR gamma beam maybe powered by Inverse Compton Scattering or by Synchrotron Radiation of electron pair beam respectively at GeVs or PeVs energies. In the latter case tens PeVs leptons (muons and later decaying PeVs electrons) might be originated while EeV nucleons Jets (protons-neutrons) are in photo-pion equilibrium with infrared photons surrounding the source. The neutron Jet might survive and remain collimated. It maybe already detected as an EeV cosmic ray anisotropy in present AGASA map pointing toward known (North Hemisphere) SGRs : SGR 1900 +14 and SGR 1806-20. If the SGR-EeV connection is correct a parasite traces of PeVs neutrino as well PeV-TeVs gamma rays might be found in present or future data records, among the others C.R. array detectors, inside the Amanda and Milagro volumes.

description: The canonical commutation relation is the hallmark of quantum theory and Heisenberg's uncertainty relation is a direct consequence of it. But despite its fundamental role in quantum theory, surprisingly, its genuine direct experimental test has hitherto not been performed. In this article, we present a novel scheme to directly test the canonical commutation relation between two dichotomic observables, by exploiting the notion of weak measurement. The imaginary part of a suitably formulated weak value enables this direct test. The measurement of the weak value of a path-qubit observable in a neutron interferometer experiment is used to verify the approach. The experiment is realized using a newly developed technique in our neutron interferometric setup where the neutron's spin/energy degree of freedom serves as ancilla.

description: We present a superfield Lax formalism of superspace sigma model based on the target space ${\cal G}/{\cal H}$ and show that a one-parameter family of flat superfield connections exists if the target space ${\cal G}/{\cal H}$ is a symmetric space. The formalism has been related to the existences of an infinite family of local and non-local superfield conserved quantities. Few examples have been given to illustrate the results.

description: We describe briefly the Palomar-Quest (PQ) digital synoptic sky survey, including its parameters, data processing, status, and plans. Exploration of the time domain is now the central scientific and technological focus of the survey. To this end, we have developed a real-time pipeline for detection of transient sources. We describe some of the early results, and lessons learned which may be useful for other, similar projects, and time-domain astronomy in general. Finally, we discuss some issues and challenges posed by the real-time analysis and scientific exploitation of massive data streams from modern synoptic sky surveys.

description: The emergence of the COVID-19 pandemic, a new and novel risk factor, leads to the stock price crash due to the investors' rapid and synchronous sell-off. However, within a short period, the quality sectors start recovering from the bottom. A stock price model has been developed during such crises based on the net-fund-flow ($Ψ_t$) due to institutional investors, and financial antifragility ($ϕ$) of a company. We assume that during the crash, the stock price fall is independent of the $ϕ$. We study the effects of shock lengths and $ϕ$ on the stock price during the crises period using the $Ψ_t$ obtained from synthetic and real fund flow data. We observed that the possibility of recovery of stock with $ϕ>0$, termed as quality stock, decreases with an increase in shock-length beyond a specific period. A quality stock with higher $ϕ$ shows V-shape recovery and outperform others. The shock length and recovery period of quality stock are almost equal that is seen in the Indian market. Financially stressed stocks, i.e., the stocks with $ϕ<0$, show L-shape recovery during the pandemic. The stock data and model analysis shows that the investors, in uncertainty like COVID-19, invest in quality stocks to restructure their portfolio to reduce the risk. The study may help the investors to make the right investment decision during a crisis.

description: Examination of patients-it sets itself the goal of choosing treatment methods by correctly diagnosing their diseases. Examination maboynida should take a very careful approach to a change in the stream observed in the body of the patient. Because this condition can help determine the etiological factors of common and dental diseases observed in the body. One of the main conditions for examining patients is the study of their complaints. The study of the complaint of patients is distinguished from the main stages of diagnosis of the disease.

description: We propose that the inhomogeneous patterns seen by STM in some underdoped superconducting cuprates could be related to a bond-order-wave instability of the staggered flux state, one of the most studied "normal" state proposed to compete with the d-wave RVB superconductor. A checkerboard pattern is obtained by a Gutzwiller renormalized mean-field theory of the t-J model for doping around 1/8. It is found that the charge modulation is always an order of magnitude smaller than the bond-order modulations. This is confirmed by an exact optimization of the wavefunction by a variational Monte Carlo scheme. The numerical estimates of the order parameters are however found to be strongly reduced w.r.t their mean-field values.

description: When Enrico Fermi discovered slow neutrons, he accounted for their great efficiency in inducing radioactivity by merely mentioning the well-known scattering cross-section between neutrons and protons. He did not refer to capture cross-section, at that early stage. It is put forward that a thermodynamic approach to neutron-proton radiative capture then widely debated might underlie his early accounts. Fermi had already met with a similar approach, and repeatedly used it.
