description: Purpose: evaluation and comparison of volumetric modulated RapidarcTM radiotherapy (RA-IMRT) vs linac based Stereotactic body radiotherapy (SBRT) in the salvage treatment of isolated lymph node recurrences in patients affected by gynaecological cancer. 
Materials and Methods From January 2010 to September 2011, 15 patients affected by isolated lymph nodes recurrence of gynaecological cancer underwent salvage radiotherapy after conventional imaging staging with CT and 18-FDG-PET/CT. Two different radiotherapy techniques were used in this study: RA-IMRT (RapidarcTM implemented radiotherapy Varian Medical System, Palo Alto, CA, USA) or SBRT (BrainLAB, Feldkirchen, Germany). 
Five patients underwent CT scan and all patients underwent 18FDG-PET/CT for pre-treatment evaluation and staging. 
The mean total dose delivered was 54.3 Gy (range 50-60 Gy with conventional fractionation and 27.4 Gy (range 12-40 Gy hypofractionation) for RA-IMRT and SBRT respectively. 
The mean number of fractions was 27.6 fractions (range 25-31) and 3-4 fractions , the mean overall treatment duration was 40.5 days (range 36-45) and 6.5 days (range 5-8 days) for RA-IMRT and SBRT respectively. 
Results: 
At the time of the analysis, October 2011, the overall survival was 92.3 % (80% for RA-IMRT and 100% for SBRT). Six patients are alive with no evidence of disease and also six patients are alive with clinically evident disease in other sites (40% and 50% patients RA-IMRT vs SBRT respectively, one patient died for systemic progression of disease and two patient were not evaluable at this time.
Conclusions: Our preliminary results showed that, the use of RA-IMRT and SBRT are an excellent local therapy for isolated lymph nodes recurrences of gynaecological cancer with a good toxicity profile and local control rate, even if any long term survivors would be expected. New treatment modalities like Cyberknife are also being implemented.

Fundamentals of the Firm and Beta Estimation

Subjects: fundamental beta, cost of equity, private firms, valuation, cost of capital

description: For publicly traded firms, it is common to estimate the beta and the cost of equity assuming the perspective of the marginal investor. Unfortunately, the same assumption cannot be applied directly to the private firms. Indeed, it is quite common that investor is the entrepreneur and he/she is not diversified. Also, for the private firms there are not a historical price information that are needed to estimate beta. One way to solve the problem is the “fundamental beta”. It estimates the Beta of the firm on the basis of its fundamentals by applying the coefficient estimates on the basis of the analysis developed on the on the publicly traded firms. In this paper we estimate the beta on the fundamentals of the U.S. publicly traded firms in the year 2022.

description: We study an $f(R)$ approximation to asymptotic safety, using a family of non-adaptive cutoffs, kept general to test for universality. Matching solutions on the four-dimensional sphere and hyperboloid, we prove properties of any such global fixed point solution and its eigenoperators. For this family of cutoffs, the scaling dimension at large $n$ of the $n^\text{th}$ eigenoperator, is $λ_n\propto b\, n\ln n$. The coefficient $b$ is non-universal, a consequence of the single-metric approximation. The large $R$ limit is universal on the hyperboloid, but not on the sphere where cutoff dependence results from certain zero modes. For right-sign conformal mode cutoff, the fixed points form at most a discrete set. The eigenoperator spectrum is quantised. They are square integrable under the Sturm-Liouville weight. For wrong sign cutoff, the fixed points form a continuum, and so do the eigenoperators unless we impose square-integrability. If we do this, we get a discrete tower of operators, infinitely many of which are relevant. These are $f(R)$ analogues of novel operators in the conformal sector which were used recently to furnish an alternative quantisation of gravity.

description: Abstract

Crime has been a fundamental problem ever as the dawn of human civilization and man’s endeavours to struggle with this problem have only moderately succeeded. After the inception, Bangladesh has been facing the problems of crime, criminality and dishonesty with its diversified forms. Crime in Bangladesh is at hand in diverse forms such as Trafficking Money Extortion, contact killing, Fraud, Human Trafficking, Robbery, corruption,  Black-marketing, Political Violence, terrorism etc. This study is an endeavour to represent the inclusive and complete chronological scrutiny of crime in present-day Bangladesh with indications to crime inclination and its allied grounds. In addition, the study stated mainly the universal crimes are the economic crimes; conversely, the tendency of non-economic crimes particularly political crime is shocking. To diminish crime in Bangladesh the key motivators are akin to political patronage, poverty, unemployment, broken home, initiation by friends and lack of knowledge must be come out. Further, a variety of effectual appraises together with effective laws and policy, appropriate justice system, police reform, public consciousness, must be guaranteed. This study has been conducted mostly based on primary data.  Secondary data also used for comparison to other developed countries by reviewing official publications, both national and international, on diverse aspects of crime of some developed countries, Published and unpublished research papers, working papers, seminar and conference proceedings, online resources have also been used. This article analyses the effectiveness of traditional law and justice in Bangladesh in different scale & socio-political context as well as comparison to other developed countries to minimize the gap through initiate various steps and policies. Therefore, a general overview of trends and practice of criminal behaviour is provided which is followed by historical evolution of crime and criminality in the British and Pakistani rule over Bangladesh.

description: Recent observations support the hypothesis that a large fraction of "short-hard" gamma-ray bursts (SHBs) are associated with compact binary inspiral. Since gravitational-wave (GW) measurements of well-localized inspiraling binaries can measure absolute source distances, simultaneous observation of a binary's GWs and SHB would allow us to independently determine both its luminosity distance and redshift. Such a "standard siren" (the GW analog of a standard candle) would provide an excellent probe of the relatively nearby universe's expansion, complementing other standard candles. In this paper, we examine binary measurement using a Markov Chain Monte Carlo technique to build the probability distributions describing measured parameters. We assume that each SHB observation gives both sky position and the time of coalescence, and we take both binary neutron stars and black hole-neutron star coalescences as plausible SHB progenitors. We examine how well parameters particularly distance) can be measured from GW observations of SHBs by a range of ground-based detector networks. We find that earlier estimates overstate how well distances can be measured, even at fairly large signal-to-noise ratio. The fundamental limitation to determining distance proves to be a degeneracy between distance and source inclination. Overcoming this limitation requires that we either break this degeneracy, or measure enough sources to broadly sample the inclination distribution. (Abridged)

description: BiOCu_{1-y}S was recently reported to superconduct at T=5.8 K at y~0.15. Band structure calculations indicate that stoichiometric BiOCuS is a band insulator. In this paper, I show that hole-doped (whether in the virtual crystal approximation or with actual Cu vacancies) BiOCuS is on the verge of a ferromagnetic instability (cf. Pd metal), and therefore conventional superconductivity with Tc~6 K is quite unlikely. Presumably, hole-doped BiOCuS is another example of superconductivity mediated by spin-fluctuations

Did you ever migrate preservation data from one digital preservation platform to another ?

name: Hulstaert, Arnaud
Publisher: name: Zenodo
Year: 2024

description: This presentation gives insights on the lessons learned concerning a secured and trustworthy migration of 4 Pb of long-term preservation data stored on a cold storage platform.

The Belgian Science Policy Office (Belspo) has since 2015 long term digital preservation service for digital artifacts from the federal state. The technical architecture is based on a hyper secured ring network topology integrating all users and data centres. The two data centres are completely redundant and are equipped with an identical hardware infrastructure where cold storage is used as the main preservation methodology. Ingest, load balancing, authentication of users, integrity checks, file formats check, REST Api services, monitoring and retrieve workflows have been integrated in one middleware system. Belspo issued a tender procedure for the operationalisation of the hardware, software and service desk which was granted to a private partner.

The contract ended in 2022 and Belspo decided not to prolong the contract but to develop a renewed hard- and software architecture in-house with the Belgian association Smals, within the same yearly budget. Belspo launched a co-creation activity with Smals to setup a migration path and planning for the 4 Petabyte of unique volume of digital cultural heritage, research data and metadata, duplicated in both data centres. The first experiments with Arcsys showed that a simple installation, programming, and configuration did not permit to read the objects on the LTO7 tapes. A new methodology had been put in place to transfer the data in a secured way, within budget.

We stopped all new ingest in 2023, isolated the written LTO7 tapes, reconfigured one data centre and cold storage with Arcsys and began the one-by-one content migration via the Arcsys architecture with integrity and format check from one data centre to the other over secured network connectivity. Once finished the inverse operation started for guaranteeing a smooth duplication, while keeping offline the old tapes in case of lost or disaster which turned out to be an interesting decision.

Two years later the operation is still going on and nearly to finish, but with a 100% confidence not to have lost any bit.

description: We study dark matter production at CERN LHC from black hole remnants (BHR). We find that the typical mass of these BHR at LHC is ~ 5-10 TeV which is heavier than other dark matter candidates such as: axion, axino, neutralino etc. We propose the detection of this dark matter via single jet production in the process pp -> jet +BHR(dark matter) at CERN LHC. We find that for zero impact parameter partonic collisions, the monojet cross section is not negligible in comparison to the standard model background and is much higher than the other dark matter scenarios studied so far. We also find that dσ/dp_T of jet production in this process increases as p_T increases, whereas in all other dark matter scenarios the dσ/dp_T decreases at CERN LHC. This may provide an useful signature for dark matter detection at LHC. However, we find that when the impact parameter dependent effect of inelasticity is included, the monojet cross section from the above process becomes much smaller than the standard model background and may not be detectable at LHC.

description: We monitored the BL Lac object S5 0716+714 in the optical band during October 2008, December 2008 and February 2009 with a best temporal resolution of about 5 minutes in the BVRI bands. Four fast flares were observed with amplitudes ranging from 0.3 to 0.75 mag. The source remained active during the whole monitoring campaign, showing microvariability in all days except for one. The overall variability amplitudes are delta B ~ 0.89 mag, delta V ~ 0.80 mag, delta R ~ 0.73 mag and delta I ~0.51 mag. Typical timescales of microvariability range from 2 to 8 hours. The overall V - R color index ranges from 0.37 to 0.59. Strong bluer- when-brighter chromatism was found on internight timescales. However, different spectral behavior was found on intranight timescales. A possible time lag of ~ 11 mins between B and I bands was found on one night. The shock-in-jet model and geometric effects can be applied to explain the source's intranight behavior.

description: Differentiable physics is a powerful tool in computer vision and robotics for scene understanding and reasoning about interactions. Existing approaches have frequently been limited to objects with simple shape or shapes that are known in advance. In this paper, we propose a novel approach to differentiable physics with frictional contacts which represents object shapes implicitly using signed distance fields (SDFs). Our simulation supports contact point calculation even when the involved shapes are nonconvex. Moreover, we propose ways for differentiating the dynamics for the object shape to facilitate shape optimization using gradient-based methods. In our experiments, we demonstrate that our approach allows for model-based inference of physical parameters such as friction coefficients, mass, forces or shape parameters from trajectory and depth image observations in several challenging synthetic scenarios and a real image sequence.

description: We introduce a powerful connection between Ehrhart theory and additive number theory, and use it to produce infinitely many new classes of inequalities between the coefficients of the $h^*$-polynomial of a lattice polytope. This greatly improves upon the three known classes of inequalities, which were proved using techniques from commutative algebra and combinatorics. As an application, we deduce all possible `balanced' inequalities between the coefficients of the $h^*$-polynomial of a lattice polytope containing an interior lattice point, in dimension at most 6.

description: We performed elastic neutron scattering measurements on the charge- and magnetically-ordered multiferroic material LuFe(2)O(4). An external electric field along the [001] direction with strength up to 20 kV/cm applied at low temperature (~100 K) does not affect either the charge or magnetic structure. At higher temperatures (~360 K), before the transition to three-dimensional charge-ordered state, the resistivity of the sample is low, and an electric current was applied instead. A reduction of the charge and magnetic peak intensities occurs when the sample is cooled under a constant electric current. However, after calibrating the real sample temperature using its own resistance-temperature curve, we show that the actual sample temperature is higher than the thermometer readings, and the "intensity reduction" is entirely due to internal sample heating by the applied current. Our results suggest that the charge and magnetic orders in LuFe(2)O(4) are unaffected by the application of external electric field/current, and previously observed electric field/current effects can be naturally explained by internal sample heating.

description: The generalized coherent states attached to the Jacobi group realize the squeezed states. Imposing hermitian conjugacy to the generators of the Jacobi algebra, we find out the form of the weight function appearing in the scalar product. We show effectively the orthonormality of the base functions with respect to the scalar product. From the explicit form of the reproducing kernel, we find out the expression of the multiplier in a holomorphic representation of the Jacobi group.

description: The occurrence of Leber Hereditary Optic Neuropathy in association with dystonia is exceedingly rare. There have been only a few previously reported cases describing this clinical phenotype with the mitochondrial DNA 14459 G>A/ND6 mutation. This mutation has been described to also manifest as isolated Leber Hereditary Optic Neuropathy or Leigh Syndrome/Leigh-like Syndrome in a very small number of patients. We report the case of a 27-year-old female who presented with bilateral sequential optic neuropathy on a background of non-familial generalized dystonia. Magnetic resonance imaging performed during childhood had shown bilateral high signal changes in the basal ganglia. Extensive testing for a possible autoimmune etiology was unrevealing. Her vision did not improve with aggressive steroid and plasma exchange treatment. Targeted genetic testing revealed a mitochondrial DNA 14459 G>A/ND6 mutation. Genetic analysis for the mitochondrial DNA 14459 G>A/ND6 mutation should be tested in a patient presenting with bilateral sequential optic neuropathy with co-morbid dystonia.

description: The global shortage of IT professionals has been identified as one of the most serious threats against the continued growth of offshore IT service providers (OSPs). As a result, talent management has become a key competitive strategy for OSPs. However, how talent management contributes towards the performance of OSPs remains poorly understood in relation to its interaction with knowledge. To examine this issue, we draw on a sample of 68 OSPs in India to test the effects of talent management and external knowledge on performance. The results confirmthat both external knowledge and talent management are positively related to firmperformance and that the latter has strong mediating effects on the relationship between external knowledge and firm performance. The results suggest that OSPs should consider talent management as a mechanism through which knowledge resources can be exploited to enhance firm performance. The managerial implications and limitations of the findings are also discussed. © 2012 Australian Human Resources Institute.

description: We derive necessary and sufficient conditions for the approximate correctability of a quantum code, generalizing the Knill-Laflamme conditions for exact error correction. Our measure of success of the recovery operation is the worst-case entanglement fidelity of the overall process. We show that the optimal recovery fidelity can be predicted exactly from a dual optimization problem on the environment causing the noise. We use this result to obtain an easy-to-calculate estimate of the optimal recovery fidelity as well as a way of constructing a class of near-optimal recovery channels that work within twice the minimal error. In addition to standard subspace codes, our results hold for subsystem codes and hybrid quantum-classical codes.

Studies of Erythrocyte Membrane Alterations in Duchenne Muscular Dystrophy
Creators: name: Bridges, Michael Anthony
Publisher: name: University of British Columbia
Year: 2010

description: Duchenne Muscular Dystrophy (DMD) appears to be a generalized plasma membrane disorder involving many body tissues of affected individuals, including erythrocytes. Investigation of the myopathic aspects of this disease has suffered from difficulties in distinguishing between the immediate effects of the primary lesion in muscle and the sequelae of muscle fiber necrosis. However, since there are indications that erythrocytes may also be abnormal in DMD, it may be possible to characterize this primary lesion in these cells. Furthermore, examination of erythrocytes of DMD patients and their female "carrier" relatives may reveal convenient biochemical markers of the disease which may aid both in early patient diagnosis and in carrier detection. The present investigations comprise a screening study in which a variety of chemical and biochemical techniques were employed in order to compare the structural and functional characteristics of DMD patient and carrier erythrocytes with those of normal control erythrocytes. A number of red cell abnormalities were found to be present in erythrocytes from patients with DMD or from their female carrier relatives: alterations in erythrocyte membrane phospholipid contents, in membrane-bound enzymatic activities associated with active sodium and potassium transport, as well as in those believed to be related to active calcium extrusion, and in the osmotic fragility characteristics of intact red cells. Although these findings are still tentative, they provide evidence supporting the generalized membrane defect hypothesis of DMD, as well as suggest promising avenues for further investigation of the molecular basis of DMD pathogenesis utilizing red cells. Recognized mechanisms of cellular injury are discussed in the attempt to reconcile the experimental findings of these studies with those of other investigators, and parallels are drawn between the alterations observed in DMD erythrocytes and those exhibited by erythrocytes in various other disorders and in experimental models.
Stripe order, impurities, and symmetry breaking in a diluted frustrated magnet

description: We investigate the behavior of the frustrated $J_1$-$J_2$ Ising model on a square lattice under the influence of random dilution and spatial anisotropies. Spinless impurities generate a random-field type disorder for the spin-density wave (stripe) order parameter. These random fields destroy the long-range stripe order in the case of spatially isotropic interactions. Combining symmetry arguments, percolation theory and large-scale Monte Carlo simulations, we demonstrate that arbitrarily weak spatial interaction anisotropies restore the stripe phase. More specifically, the transition temperature $T_c$ into the stripe phase depends on the interaction anisotropy $ΔJ$ via $T_c \sim 1/|\ln (ΔJ)|$ for small $ΔJ$. This logarithmic dependence implies that very weak anisotropies are sufficient to restore the transition temperature to values comparable to that of the undiluted system. We analyze the critical behavior of the emerging transition and find it to belong to the disordered two-dimensional Ising universality class, which features the clean Ising critical exponents and universal logarithmic corrections. We also discuss the generality of our results and their consequences for experiments.

Numerical Simulations of Supernova Dust Destruction. I. Cloud-crushing and Post-processed Grain Sputtering

description: We investigate through hydrodynamic simulations the destruction of newly-formed dust grains by sputtering in the reverse shocks of supernova remnants. Using an idealized setup of a planar shock impacting a dense, spherical clump, we implant a population of Lagrangian particles into the clump to represent a distribution of dust grains in size and composition. We then post-process the simulation output to calculate the grain sputtering for a variety of species and size distributions. We explore the parameter space appropriate for this problem by altering the over-density of the ejecta clumps and the speed of the reverse shocks. Since radiative cooling could lower the temperature of the medium in which the dust is embedded and potentially protect the dust by slowing or halting grain sputtering, we study the effects of different cooling methods over the time scale of the simulations. In general, our results indicate that grains with radii less than 0.1 microns are sputtered to much smaller radii and often destroyed completely, while larger grains survive their interaction with the reverse shock. We also find that, for high ejecta densities, the percentage of dust that survives is strongly dependent on the relative velocity between the clump and the reverse shock, causing up to 50% more destruction for the highest velocity shocks. The fraction of dust destroyed varies widely across grain species, ranging from total destruction of Al2O3 grains to minimal destruction of Fe grains (only 20% destruction in the most extreme cases). C and SiO2 grains show moderate to strong sputtering as well, with 38% and 80% mass loss. The survival rate of grains formed by early supernovae is crucial in determining whether or not they can act as the "dust factories" needed to explain high-redshift dust.

Sizable Time-reversal violating effects in bottom baryon decays

description: We study time-reversal~(T) asymmetries in the charmless two-body decays of antitriplet bottom baryons. We find that in ${\bf B}_b \to {\bf B}_n P$ with ${\bf B}_b = (Ξ_b ^- , \,Ξ_b^0, \,Λ_b)$ and ${\bf B}_n(P)$ a octet baryon (pseudoscalar meson), the positive and negative helicity amplitudes are both sizable, resulting in the large T-violating effects. Particularly, the T-odd parameters, $β_w$, for the color-enhanced channels are expected to be around $40\%$ and $-25\%$ in $b\to s $ and $b\to d $ transitions for the standard model, which can be measured by the experiments at LHCb, respectively. On the other hand, in ${\bf B}_b \to {\bf B}_n V(γ)$ with $V(γ)$ a vector meson~(photon), the decays are predominated by a single helicity amplitude, and the T violating effects by the correlations among spins are suppressed. We also explore the T violating observables for the $Ξ_b$ decays based on the angular distributions.

description: A 51-year-old female sanitation worker in China developed bilateral neuroretinitis due to scrub typhus. Initially diagnosed with ‘scrub typhus infected pneumonia’, her symptoms subsided within seven days of chloramphenicol treatment. However, two weeks later, she experienced acute bilateral vision loss. Fundoscopy revealed swollen optic discs, exudates, and a small macular pigment epithelial detachment. Diagnosed with scrub typhus-related neuroretinitis, her vision improved after methylprednisolone treatment. This represents the first reported case of such in southern China, suggesting a delayed immune response to scrub typhus. Early diagnosis and proper treatment are crucial for vision prognosis.

The spontaneously formed stripe domains are used as a field-controlled optical grating, allowing for active spatiotemporal control of light. We discuss the basic ideas behind the approach and provide a quantitative description of the field dependence of the obtained light patterns. Finally, we calculate and experimentally verify the efficiency of our magneto-optical grating.

description: This thesis presents the outcomes of my Ph.D. course in telecommunications engineering. The focus of my research has been on Global Navigation Satellite Systems (GNSS) and in particular on the design of aiding schemes operating both at position and physical level and the evaluation of their feasibility and advantages. 
Assistance techniques at the position level are considered to enhance receiver availability in challenging scenarios where satellite visibility is limited. Novel positioning techniques relying on peer-to-peer interaction and exchange of information are thus introduced. More specifically two different techniques are proposed: the Pseudorange Sharing Algorithm (PSA), based on the exchange of GNSS data, that allows to obtain coarse positioning where the user has scarce satellite visibility, and the Hybrid approach, which also permits to improve the accuracy of the positioning solution. 
At the physical level, aiding schemes are investigated to improve the receiver’s ability to synchronize with satellite signals. An innovative code acquisition strategy for dual-band receivers, the Cross-Band Aiding (CBA) technique, is introduced to speed-up initial synchronization by exploiting the exchange of time references between the two bands. In addition vector configurations for code tracking are analyzed and their feedback generation process thoroughly investigated.
