Oxygen transfer reaction from cyclic nitrones to triphenylphosphine
Creators: name: Agolini, Franco
Publisher: name: University of British Columbia
Year: 2011

description: The compounds in the series from triphenylphosphine to triphenylbismuthine were examined as acceptors in oxygen transfer reactions involving the l-pyrroline-l-oxides. Triphenylphosphine was found to offer a useful route from the l-pyrroline-l-oxides to the corresponding pyrrolines. The second part of this work is centred on the structural investigation of Sanno's base (XV) (l), obtained as a by-product in the reductive cyclization of ethyl 2-acetyl-2-ethyl-4-methyl-3-nitromethyl valerate (aγ -nitro-ketone) and formulated by the author as having the Δ’ -pyrroline structure; this compound has since been found to be a cyclic nitrone (XVI). In the case of this complex nitrone, the oxygen transfer reaction to triphenylphosphine has been successful, yielding two isomeric Δ' -pyrrolines. The isolation of a Δ -pyrroline structure is confirmation of the proposed cyclic nitrone (XVI) structure for Sanno's base and as this provides a practical application of this reaction in structural work as well as showing that triphenylphosphine will reduce N-oxides in the presence of an ester group.

description: Gamma Ray Burst has been widely believed in last decade to be
super-explosions: the Fireball. We are argue on the contrary that GRBs (as well
as Soft Gamma Repeaters SGR) are precessing Gamma Jets. We remind the list of
contradiction that Fireball and its smaller galactic version, the Magnetar,
have to face. In particular the existence of weak isolated X-ray precursor
signal before the main Gamma Ray Burst and (rare SGR) events disagree with any
explosive, one shoot, scenarios either isotropic or wide-beamed. We interpret
them as earlier marginal blazing of outlying X conical Jet tails of precessing,
spinning gamma Jet.

description: We use analytic calculations of the post-recombination gravitational effects of cosmic strings to estimate the resulting CMB power spectrum, bispectrum and trispectrum. We place a particular emphasis on multipole regimes relevant for forthcoming CMB experiments, notably the Planck satellite. These calculations use a flat sky approximation, generalising previous work by integrating string contributions from last scattering to the present day, finding the dominant contributions to the correlators for multipoles l > 50. We find a well-behaved shape for the string bispectrum (without divergences) which is easily distinguishable from the inflationary bispectra which possess significant acoustic peaks. We estimate that the nonlinearity parameter characterising the bispectrum is approximately f_NL \sim -20 (given present string constraints from the CMB power spectrum. We also apply these unequal time correlator methods to calculate the trispectrum for parrallelogram configurations, again valid over a large range of angular scales relevant for WMAP and Planck, as well as on very small angular scales. We find that, unlike the bispectrum which is suppressed by symmetry considerations, the trispectrum for cosmic strings is large. Our current estimate for the trispectrum parameter is tau_NL \sim 10^5, which may provide one of the strongest constraints on the string model as estimators for the trispectrum are developed.

description: Acute aortic dissections are unpredictable aortic catastrophes. Although significant recent improvements have been accomplished in the treatment and management of aortic dissections, a significant amount is still not fully understood regarding this deadly condition. Comprehension of aortic dissections is especially important due to the impact of the disease, since a lot of patients die before reaching the hospital and a significant number of the ones who do survive the initial event end up dying during follow-up. The epidemiology and disease characteristics of these conditions are still under investigation and not completely clear. In this article we aim to review the current knowledge on the epidemiology and clinical characteristics of aortic dissections.

description: INTRODUCTION: Kidney autotransplantation (KAT) is a versatile surgical technique used to treat multiple diseases affecting the kidney. This procedure allows the reconstruction of the renal artery or vein with optimal surgical exposure reducing warm ischemia time compared to open direct repair. Although infrequently reported nowadays and despite the growing use of endovascular treatments, KAT still has a place in treating complex kidney vascular conditions. METHODS: We performed a literature review using the MEDLINE®, SCOPUS, and Web of Science databases with the combination of the terms: “kidney autotransplantation,” “renal artery,” “renal vein,” “aorta,” “aneurysm,” and “nutcracker syndrome.” All relevant English-language studies published between January 1990 and June 2022 reporting the outcomes of the KAT technique in vascular disorders were included. RESULTS: A total of 32 articles were included. Ex-vivo repair and KAT is widely described in treating renal artery aneurysms (RAA), with a reported technical success rate of 99.9%, a complication rate ranging from 6.9 to 9.4%, and a graft loss rate of up to 4.1%. The use of the laparoscopic technique for harvesting the kidney was variable throughout the series published, and heterotopic KAT was performed in most treated patients. Ex-vivo repair and KAT was successfully used after failed endovascular therapy and is a viable option in women of childbearing age with bilateral complex RAA. Concerning renal artery stenosis associated with different etiologies (fibromuscular dysplasia, Takayasu's arteritis, and neurofibromatosis type 1), significant reduction of blood pressure and the number of anti-hypertensive drugs have been reported in most patients after KAT. Results of arterial hypertension improvement associated with RAA after KAT are more variable. The use of KAT in treating nutcracker syndrome is reported with good results, even after left renal vein transposition or venous stenting failure. Other reports exist on the successful use of KAT for treating renal vein aneurysms and as an adjunct in open surgical or hybrid aortic reconstructions. CONCLUSION: Renal autotransplantation is a useful technique in the treatment of kidney vascular disorders with good overall results reported in the literature. It may be an essential adjunct in open surgical or hybrid treatments for abdominal and thoracoabdominal aortic diseases. Defining the patients who would benefit from this technique as a preferential treatment choice in different renal vessel disorders would be necessary.

Non-planar ABJM Theory and Integrability

description: Using an effective vertex method we explicitly derive the two-loop dilatation generator of ABJM theory in its SU(2)xSU(2) sector, including all non-planar corrections. Subsequently, we apply this generator to a series of finite length operators as well as to two different types of BMN operators. As in N=4 SYM, at the planar level the finite length operators are found to exhibit a degeneracy between certain pairs of operators with opposite parity - a degeneracy which can be attributed to the existence of an extra conserved charge and thus to the integrability of the planar theory. When non-planar corrections are taken into account the degeneracies between parity pairs disappear hinting the absence of higher conserved charges. The analysis of the BMN operators resembles that of N=4 SYM. Additional non-planar terms appear for BMN operators of finite length but once the strict BMN limit is taken these terms disappear.

description: INTRODUCTION: Recently published studies on peripheral arterial occlusive disease (PAOD) have revealed marked sex disparities in patient selection and treatment outcomes. In a recent retrospective study with data from 11 different countries, Portugal was highlighted as one of the countries with greater sex discrepancies related to PAOD treatment. We aimed to analyze sex specific differences in the treatment of symptomatic PAOD, concerning different variables, in a single hospital center, in Portugal. METHODS: Data on treatment of symptomatic PAOD patients from October 1st, 2020, to December 31st, 2021, were retrospectively collected from clinical registries from a single hospital center in Portugal. Different variables and post-operative outcomes were analyzed dichotomized by sex, with descriptive statistics. Statistical analyses were conducted using the IBM Statistical Package for Social Sciences (SPSS) software v28. RESULTS: A total of 220 patients, 15,9% female and 84,1% male, were treated for PAOD, in the selected period, in a hospital center from Portugal. Female patients were older (mean age of 73.8 years versus 69.5 years in male); were less likely to be treated for intermittent claudication (3% versus 6% of men); more often treated at a more advanced stage of the disease with trophic lesions (91% versus 74% of men); more likely to be offered primary major amputation (14% versus 3% of male patients); less likely to be taking statins as part of PAOD medical management (65.7% versus 77.8% of male); and had a higher 90-day mortality rate (17.1% versus 6.5% in men). They were also more frequently treated with endovascular procedures (40%) than with OSR (26%). CONCLUSION: Remarkable sex discrepancies in the treatment of PAOD were found in our hospital center. This study brings awareness to the scientific medical community for sex disparities in the management of patients with PAOD.

description: Our aim is to investigate and analyze the radio surface brightness to diameter ($Σ-D$) relation for recently detected, bright radio-continuum planetary nebulae (PNe) in the Magellanic Clouds (MC). We apply a Monte Carlo analysis in order to account for sensitivity selection effects on measured $Σ-D$ relation slopes for bright radio PNe in the MCs. In the $Σ-D$ plane these radio MCs PNe are positioned among the brightest of the nearby Galactic PNe, and are close to the $D^{-2}$ sensitivity line of the MCs radio maps. The fitted Large Magellanic Cloud (LMC) data slope appears to be influenced with survey sensitivity. This suggests the MCs radio PN sample represents just the "tip of the iceberg" of the actual luminosity function. Specifically, our results imply that sensitivity selection tends to flatten the slope of the $Σ-D$ relation. Although MCs PNe appear to share the similar evolution properties as Galactic PNe, small number of data points prevented us to further constrain their evolution properties.

Non-renormalization conditions for four-gluon scattering in supersymmetric string and field theory

description: The constraints imposed by maximal supersymmetry on multi-loop contributions to the scattering of four open superstrings in the U(N) theory are examined by use of the pure spinor formalism. The double-trace term k^2 t_8(tr F^2)^2 (where k represents an external momentum and F the Yang--Mills field strength) only receives contributions from L<=2 (where L is the loop number) while the single-trace term k^2 t_8(tr F^4) receives contributions from all L. We verified these statements up to L=5, but arguments based on supersymmetry suggest they extend to all L. This explains why the single-trace contributions to low energy maximally supersymmetric Yang--Mills field theory are more divergent in the ultraviolet than the double-trace contributions. We also comment further on the constraints on closed string amplitudes and their implications for ultraviolet divergences in N=8 supergravity.

description: A well known result of Miyaoka asserts that a complex projective manifold is uniruled if its cotangent bundle restricted to a general complete intersection curve is not nef. Using the Harder-Narasimhan filtration of the tangent bundle, it can moreover be shown that the choice of such a curve gives rise to a rationally connected foliation of the manifold. In this note we show that, conversely, a movable curve can be found so that the maximal rationally connected fibration of the manifold may be recovered as a term of the associated Harder-Narasimhan filtration of the tangent bundle.

description: The unequivocal detection of entanglement between two distinct matter-wave pulses is a significant challenge that has yet to be experimentally demonstrated. We describe a realistic scheme to generate and detect continuous variable entanglement between two atomic matter-wave pulses produced via degenerate four-wave-mixing from an initially trapped Bose-Einstein condensate loaded into a one-dimensional optical lattice. We perform a comprehensive numerical investigation for fixed condensate parameters to determine the maximum violation of separability and Einstein-Podolsky-Rosen inequalities for field quadrature entanglement, and describe and simulate an experimental scheme for measuring the necessary quadratures.

description: We derive the moment generating function for photon emissions from a single molecule driven by laser excitation. The frequencies of the fluoresced photons are explicitly considered. Calculations are performed for the case of a two level dye molecule, showing that measured photon statistics will display a strong and non-intuitive dependence on detector bandwidth. Moreover, it is demonstrated that the anti-bunching phenomenon, associated with negative values of Mandel's Q-parameter, results from correlations between photons with well separated frequencies.

Simultaneity, radar 4-coordinates and the 3+1 point of view about
  accelerated observers in special relativity
Creators: name: D. Alba

Publisher: name: INFN Open Access Repository
Year: 2004

description: After a review of the 1+3 point of view on non-inertial observers and of the
problems of rotating reference frames, we underline that was is lacking in
their treatment is a good global notion of simultaneity due to the restricted
validity of the existing 4-coordinates associated to an accelerated observer
(like the Fermi normal ones). We show that the relativistic Hamiltonian 3+1
point of view, based on a 3+1 splitting of Minkowski space-time with a
foliation whose space-like leaves are both simultaneity and Cauchy surfaces,
allows to find a solution to such problems, if we take into account M$\o$ller's
definition of allowed 4-coordinate transformations extended to radar
4-coordinates. Rigidly rotating relativistic reference frames are shown not to
exist. We give explicit foliations, with simultaneity surfaces (also space-like
hyper-planes) non orthogonal to the non-inertial observer world-line, which
correspond to a good notion of simultaneity for suitable (mutually balancing)
translational and rotational accelerations. This allows to evaluate the
simultaneity-dependent one-way speed of light and to give the 3+1 description
of both the rotating disk and the Sagnac effect. It is also shown how a GPS
system of spacecrafts may establish a grid of admissible radar 4-coordinates
and how the ACES mission can employ a variant of this method adapted to Earth's
rotation in the evaluation of the one-way time transfer to detect the deviation
from Einstein convention on the synchronization of inertial clocks implied by
such a notion of simultaneity. We show that in parametrized Minkowski theories
all the admissible notions of simultaneity are gauge equivalent ({\it
conventionality of simultaneity}) and, as an example, we describe Maxwell
theory in non-inertial systems with any admissible notion of simultaneity.

description: Polycyclic Aromatic Hydrocarbons (PAHs) are widely accepted as the carriers of the Aromatic Infrared Bands (AIBs), but an unambiguous identification of any specific interstellar PAH is still missing. For polar PAHs, pure rotational transitions can be used as fingerprints for identification. Combining dedicated experiments, detailed simulations and observations, we explored the mm domain to search for specific rotational transitions of corannulene (C20H10). We performed high-resolution spectroscopic measurements and a simulation of the emission spectrum of UV-excited C20H10 in the environment of the Red Rectangle, calculating its synthetic rotational spectrum. Based on these results, we conducted a first observational campaign at the IRAM 30m telescope towards this source to search for several high-J rotational transitions of (C20H10). The laboratory detection of the J = 112 134 transition at 137.615 GHz. Comparing the noise level with the synthetic spectrum, we are able to estimate an upper limit to the fraction of carbon locked in corannulene of about 1.0x10(-5) relative to the total abundance of carbon in PAHs. The sensitivity achieved shows that radio spectroscopy can be a powerful tool to search for polar PAHs. We compare this upper limit with models for the PAH size distribution, emphasising that small PAHs are much less abundant than predicted. We show that this cannot be explained by destruction but is more likely related to the chemistry of their formation in the environment of the Red Rectangle.
