Radiofrequency nerve ablation for lower back pain, Case Report
Creators: name: Dugonjić, Mario
Publisher: name: Zenodo
Year: 2022

description: Introduction: Back pain is a common condition that many people experience. In fact, over 80% of the world's population will have lower back pain at some point in their life.1 Radiofrequency ablation, also called rhizotomy, is a nonsurgical, minimally invasive procedure that uses heat to reduce or stop the transmission of pain, it is an emerging treatment option for chronic low back pain.2 Case description: A 65-year-old patient with lumbar spine pain comes in for an examination at a pain management facility, which is part of Anesthesiology, intensive care medicine and pain management clinic of the Clinical hospital centar Rijeka. At the first examination, the patient complains of severe pain in the lumbar spine with propagation in the left leg, and also complains of pain in both sacroiliac joints. The pain is chronic and intensifies during walking or standing. According to the performed MR, diagnoses of degenerative changes on vertebral segments from L2 - S1 are made. Additional physician finding, efflorescence of herpes zoster on the sacral region. The patient used tramadol chloride / paracetamol 37.5mg / 325mg 3 to 4 times daily and celecoxib 100mg twice daily, orally. Within period of pain management, 3 facet joint blocks, one medial branch block, and an acupuncture procedure were performed. There is a satisfactory reduction in pain for the next 3 months after each procedure and return to full mobility, with discontinuation of oral therapy. The patient underwent radiofrequency ablation of the medial branch nerve at L2, L3, L4, L5 vertebrae bilateral, due to the long-lasting analgesic effect. The ablation procedure proceeds smoothly without neurological outbursts, loss of sensation and mobility of the lower limbs with a corresponding long-lasting analgesic effect with the cessation of oral therapy. Discussion: Radiofrequency ablation is a safe and long-lasting treatment option for patients who have experienced successful pain relief after a diagnostic nerve/pain receptor block injection. Conclusion: Pain relief after medial branch nerve ablation may last from 9 months to more than 2 years. It is possible the nerve will regrow through the burned lesion that was created by radiofrequency ablation. If the nerve regrows, it is usually 6-12 months after the procedure. The procedure can be repeated if needed.

description: (abridged) The technique of gravitational microlensing is currently unique in its ability to provide a sample of terrestrial exoplanets around both Galactic disk and bulge stars, allowing to measure their abundance and determine their distribution with respect to mass and orbital separation. In order to achieve these goals in reasonable time, a well-coordinated effort involving a network of either 2m or 4 x 1m telescopes at each site is required. It could lead to the first detection of an Earth-mass planet outside the Solar system, and even planets less massive than Earth could be discovered. From April 2008, ARTEMiS (Automated Robotic Terrestrial Exoplanet Microlensing Search) is planned to provide a platform for a three-step strategy of survey, follow-up, and anomaly monitoring. As an expert system embedded in eSTAR (e-Science Telescopes for Astronomical Research), ARTEMiS will give advice on the optimal targets to be observed at any given time, and will also alert on deviations from ordinary microlensing light curves by means of the SIGNALMEN anomaly detector. While the use of the VOEvent (Virtual Observatory Event) protocol allows a direct interaction with the telescopes that are part of the HTN (Heterogeneous Telescope Networks) consortium, additional interfaces provide means of communication with all existing microlensing campaigns that rely on human observers. The success of discovering a planet by microlensing critically depends on the availability of a telescope in a suitable location at the right time, which can mean within 10 min. Real-time modelling offers the opportunity of live discovery of extra-solar planets, thereby providing ''Science live to your home''.

The Extended Variational Principle for Mean-Field, Classical Spin Systems

description: The purpose of this article is to obtain a better understanding of the extended variational principle (EVP). The EVP is a formula for the thermodynamic pressure of a statistical mechanical system as a limit of a sequence of minimization problems. It was developed for disordered mean-field spin systems, spin systems where the underlying Hamiltonian is itself random, and whose distribution is permutation invariant. We present the EVP in the simpler setting of classical mean-field spin systems, where the Hamiltonian is non-random and symmetric. The EVP essentially solves these models. We compare the EVP with another method for mean-field spin systems: the self-consistent mean-field equations. The two approaches lead to dual convex optimization problems. This is a new connection, and it permits a generalization of the EVP.

description: We study a non-ergodic transition in a many-body Langevin system. We first derive an equation for the two-point time correlation function of density fluctuations, ignoring the contributions of the third- and fourth-order cumulants. For this equation, with the average density fixed, we find that there is a critical temperature at which the qualitative nature of the trajectories around the trivial solution changes. Using a method of dynamical system reduction around the critical temperature, we simplify the equation for the time correlation function into a two-dimensional ordinary differential equation. Analyzing this differential equation, we demonstrate that a non-ergodic transition occurs at some temperature slightly higher than the critical temperature.

description: We present MeerKAT neutral hydrogen (HI) observations of the Fornax A group, that is likely falling into the Fornax cluster for the first time. Our HI image is sensitive to 1.4 x 10$^{19}$ cm$^{-2}$ over 44.1 km s$^{-1}$, where we detect HI in 10 galaxies and a total of 1.12 x 10$^{9}$ Msol of HI in the intra-group medium (IGM). We search for signs of pre-processing in the 12 group galaxies with confirmed optical redshifts that reside within our HI image. There are 9 galaxies that show evidence of pre-processing and we classify the pre-processing status of each galaxy, according to their HI morphology and gas (atomic and molecular) scaling relations. Galaxies yet to experience pre-processing have extended HI disks, a high HI content with a H$_2$-to-HI ratio an order of magnitude lower than the median for their stellar mass. Galaxies currently being pre-processed display HI tails, truncated HI disks with typical gas ratios. Galaxies in the advanced stages of pre-processing are HI deficient. If there is any HI, they have lost their outer HI disk and efficiently converted their HI to H$_2$, resulting in H$_2$-to-HI ratios an order of magnitude higher than the median for their stellar mass. The central, massive galaxy in our group underwent a 10:1 merger 2 Gyr ago, and ejected 6.6 - 11.2 x 10$^{8}$ Msol of HI that we detect as clouds and streams in the IGM, some forming coherent structures up to 220 kpc in length. We also detect giant (100 kpc) ionised hydrogen (H$α$) filaments in the IGM, likely from cool gas being removed (and ionised) from an infalling satellite. The H$α$ filaments are situated within the hot halo of NGC 1316 and some regions contain HI. We speculate that the H$α$ and multiphase gas is supported by magnetic pressure (possibly assisted by the AGN), such that the hot gas can condense and form HI that survives in the hot halo for cosmological timescales.

description: Fluvial deposits of the S. Maria di Ciciliano Formation crop out near Montecastrilli (Terni), in the southwestern branch of the Tiberino Basin.  Many specimens of plants ("mummified" woods, fruits and seeds), freshwater molluscs, ostracods, vertebrate bones and coprolites were collected at Torre Picchio. This small outcrop contains a fairly rich record of fruits and seeds, among which about 50 species were identified; the most frequent invariably belong to submerged, floating and emergent aquatic herbs, possibly because these were buried not far from their place of growth, thus representing the ancient local vegetation.  The fruits and seeds of woody plants, including several exotic elements, were transported from neighbouring areas and indicate a paleoclimate similar to the present day, though slightly wetter.  Among molluscs, three distinct assemblages were found, indicating fluvial, swampy and lacustrine environment, respectively.  They contain taxa of biochronological interest, most of them typical of Early Pleistocene deposits (late Villafranchian), but making their first appearance in the Late Pliocene (Middle Villafranchian). One species, Margarifera (Pseudunio) auricularia, represents the oldest record everywhere, since it was known, so far, only from the Middle Pleistocene upwards.  As palaeoenvironmental indicators, the ostracods complete the information given by molluscs.  Vetrebrates are represented by large and small mammals, rare birds, reptiles, amphibians and some fishes.  A great number of coprolites was collected as well.  The mammal assemblage shows affinities with the Costa S. Giacomo and Olivola F. U. (Middle and Late Villafranchian, Late Pliocene). Mimomys medasensis, an Iberoccitane element, is signaled for the first time in Italy.  From the geological point of view, the S. Maria di Ciciliano Fm. is interfingering with the marine Chiani-Tevere Fm., which is mostly Santernian in age and lies unconformably on the Middle Pliocene cycle. Only in some areas representing a structural low, the continuous transition between the lower portion of this unit and Late Pliocene deposits may be observed before the heteropic episodes.  This fact suggests some inconsistencies between chronostratigraphy and biochronology in the examined area because some taxa indicate a latest Pliocene age.  A heterochrony in the extinction of some species of plants and animals is suggested as a possible solution to the problem.

description: A class of previously unknown strong-interaction corrections is found to enhance the rate of non-leptonic decays of the b quark by 5-8 percent. This effect decreases the predicted fraction of semi-leptonic decays and brings it into fair agreement with experimental results. As well as solving a long-standing puzzle of measurements disagreeing with the Standard Model prediction, our work suggests a way for future precise studies of non-leptonic $b$ quark decays and their application to searching for "new physics."

THE PLEISTOCENE BATHYAL TELEOSTEAN FAUNA OF ARCHI (SOUTHERN ITALY): PALAEOECOLOGICAL AND PALAEOBIOGEOGRAPHIC IMPLICATIONS
Creators: name: GIRONE, ANGELA
Publisher: name: Università degli Studi di Milano
Year: 2003

description: The early-middle Pleistocene teleostean fauna of the Archi section, cropping out along the Calabrian side of the Messina Straits was studied.  The integrated approach, based on the palaeobathymetric method coupled with the palaeoecological approach, already used on deep circalittoral and epibathyal assemblages, was applied for the palaeoenvironmental reconstruction.  The otholith benthic and benthopelagic associations, strongly bathyal in their composition, suggest a deep bathyal palaeoenvironment, 500 to 1000 m deep, which is in agreement with the invertebrate benthic faunas. Compositional, structural, and taxonomic features of the teleostean assemblages indicate clearly Atlantic or more generally oceanic affinities.  The Archi teleostean fauna indicates a palaeoceanographic pattern with deep-water and near-bottom temperature lower than 8-10°C, quite different from the Recent mediterranean.

description: We study a class of N=1 supersymmetric U(N) gauge theories and find that there exist vacua in which the low-energy magnetic effective gauge group contains multiple nonabelian factors, \prod_i SU(r_i), supported by light monopoles carrying the associated nonabelian charges. These nontrivially generalize the physics of the so-called r-vacua found in softly broken N=2 supersymmetric SU(N) QCD, with an effective low-energy gauge group SU(r) \times U(1)^{N-r}. The matching between classical and quantum (r_{1}, r_{2},...) vacua gives an interesting hint about the nonabelian duality.

description: In robotics, it is often not possible to learn useful policies using pure model-free reinforcement learning without significant reward shaping or curriculum learning. As a consequence, many researchers rely on expert demonstrations to guide learning. However, acquiring expert demonstrations can be expensive. This paper proposes an alternative approach where the solutions of previously solved tasks are used to produce an action prior that can facilitate exploration in future tasks. The action prior is a probability distribution over actions that summarizes the set of policies found solving previous tasks. Our results indicate that this approach can be used to solve robotic manipulation problems that would otherwise be infeasible without expert demonstrations.

description: Two color laser pulses are used to form an air plasma and generate broadband infrared radiation suitable as a seed for backward Raman amplification of CO2 laser pulses. Broadband radiation in the atmospheric window from 8-14 microns is observed. The infrared radiation is characterized using a long wavelength grating spectrometer specially designed to accept an ionizing laser filament at its input plane. The LWIR yield is greatly enhanced by chirping the drive pulse. Unidirectional pulse propagation simulations suggest that this is due in part to the dependence of the nonlinear refractive index on the pulse duration.

description: Η παρούσα εργασία σχεδιάστηκε για να διερευνηθεί η δυνατότητα αναπαράστασης των μετρικών, χωρικών και ποσοτικών σχέσεων από παιδιά προσχολικής ηλικίας. Το δείγμα αποτέλεσαν 31 νήπια τα οποία στα πλαίσια ενός παιχνιδιού κλήθηκαν να παρατηρήσουν προσεκτικά 4 βάσεις lego με lego και 4 σχέδια σπιτιών και να τα αναπαραστήσουν. Από την επεξεργασία των δεδομένων προέκυψε ότι οι χωρικές και ποσοτικές σχέσεις των παρατηρούμενων στοιχείων διατηρούνται στις αναπαραστάσεις των περισσότερων παιδιών, κάτι που δεν ισχύει για τις μετρικές σχέσεις. Η διατήρηση των μετρικών σχέσεων μοιάζει να είναι ευκολότερη όταν τα στοιχεία που παρουσιάζονται στα παιδιά έχουν εμφανώς άνισα μεγέθη και δυσκολότερη όταν τα στοιχεία αυτά είναι ίσα μεταξύ τους ορθογώνια
description: The present study was designed to examine the competence of respresenting metric, spatial and quantitative relations by preschoolers. The subjects were 31 preschoolers who were called to object carefully and represent four lego bases with lego on them and four house designs. Results showed that most of the preschoolers could represent spatial and quantitative relations. Metric relations seemed to be more difficult to be represented. Moreover children could easier represent objects which had obviously unequal size than objects which had equal and were rectangles

description: Motivated by the desire to do proper model building with D7-branes and fluxes, we study the motion of D7-branes on a Calabi-Yau orientifold from the perspective of F-theory. We consider this approach promising since, by working effectively with an elliptically fibred M-theory compactification, the explicit positioning of D7-branes by (M-theory) fluxes is straightforward. The locations of D7-branes are encoded in the periods of certain M-theory cycles, which allows for a very explicit understanding of the moduli space of D7-brane motion. The picture of moving D7-branes on a fixed underlying space relies on negligible backreaction, which can be ensured in Sen's weak coupling limit. However, even in this limit we find certain 'physics obstructions' which reduce the freedom of the D7-brane motion as compared to the motion of holomorphic submanifolds in the orientifold background. These obstructions originate in the intersections of D7-branes and O7-planes, where the type IIB coupling can not remain weak. We illustrate this effect for D7-brane models on CP^1 x CP^1 (the Bianchi-Sagnotti-Gimon-Polchinski model) and on CP^2. Furthermore, in the simple example of 16 D7-branes and 4 O7-planes on CP^1 (F-theory on K3), we obtain a completely explicit parameterization of the moduli space in terms of periods of integral M-theory cycles. In the weak coupling limit, D7-brane motion factorizes from the geometric deformations of the base space.

description: We propose a new estimator to measure directed dependencies in time series. The dimensionality of data is first reduced using a new non-uniform embedding technique, where the variables are ranked according to a weighted sum of the amount of new information and improvement of the prediction accuracy provided by the variables. Then, using a greedy approach, the most informative subsets are selected in an iterative way. The algorithm terminates, when the highest ranked variable is not able to significantly improve the accuracy of the prediction as compared to that obtained using the existing selected subsets. In a simulation study, we compare our estimator to existing state-of-the-art methods at different data lengths and directed dependencies strengths. It is demonstrated that the proposed estimator has a significantly higher accuracy than that of existing methods, especially for the difficult case, where the data is highly correlated and coupled. Moreover, we show its false detection of directed dependencies due to instantaneous couplings effect is lower than that of existing measures. We also show applicability of the proposed estimator on real intracranial electroencephalography data.

description: The most precise method of investigating possible space-time variations of the fine-structure constant, using high-redshift quasar absorption lines, is the many-multiplet (MM) method. For reliable results this method requires very accurate relative laboratory wavelengths for a number of UV resonance transitions from several different ionic species. For this purpose laboratory wavelengths and wavenumbers of 23 UV lines from MgI, MgII, TiII, CrII, MnII, FeII and ZnII have been measured using high-resolution Fourier Transform (FT) spectrometry. The spectra of the different ions (except for one FeII line, one MgI line and the TiII lines) are all measured simultaneously in the same FT spectrometry recording by using a composite hollow cathode as a light source. This decreases the relative uncertainties of all the wavelengths. In addition to any measurement uncertainty, the wavelength uncertainty is determined by that of the ArII calibration lines, by possible pressure shifts and by illumination effects. The absolute wavenumbers have uncertainties of typically 0.001 to 0.002 cm^(-1) (0.06 to 0.1 mAA at 2500 AA), while the relative wavenumbers for strong, symmetric lines in the same spectral recording have uncertainties of 0.0005 cm^(-1) (0.03 mAA at 2500 AA) or better, depending mostly on uncertainties in the line fitting procedure. This high relative precision greatly reduces the potential for systematic effects in the MM method, while the new TiII measurements now allow these transitions to be used in MM analyses.

description: Two polarization modes of gravitational wave are derived from the general relativity which are plus and cross modes. However, the alternative theories of gravity can yield the gravitational wave with up to six polarizations. Searching for the polarizations beyond plus and cross is an important test of general relativity. In principle, one space-borne detector, like LISA, could measure the gravitational wave polarizations from a long time observation with its orbital motion. With the comparable sensitivities, the joint LISA and TAIJI missions will improve the observations on the polarization predictions of theories beyond general relativity. In this work, a class of parameterized post-Einsteinian waveform is employed to describe the alternative polarizations, and six parameterized post-Einsteinian parameters quantifying from general relativity waveform are examined by using the LISA-TAIJI network. Our results show that the measurements on amplitudes of alternative polarizations from joint LISA-TAIJI observation could be improved by more than 10 times compared to LISA single mission in an optimal scenario.

description: We demonstrate that parity nonconserving interaction due to the nuclear weak charge Q_W leads to nonlinear magnetoelectric effect in centrosymmetric paramagnetic crystals. It is shown that the effect exists only in crystals with special symmetry axis k. Kinematically, the correlation (correction to energy) has the form H_PNC ~ Q_W (E,[B,k])(B,k), where B and E are the external magnetic and electric fields. This gives rise to magnetic induction M_PNC ~ Q_W {k(B,[k,E]) + [k,E](B,k)}. To be specific we consider rare-earth trifluorides and, in particular, dysprosium trifluoride which looks the most suitable for experiment. We estimate the optimal temperature for the experiment to be of a few kelvin. For the magnetic field B = 1 T and the electric field E = 10 kV/cm, the expected magnetic induction is 4 πM_PNC = 0.5 * 10^-11 G, six orders of magnitude larger than the best sensitivity currently under discussion. Dysprosium has several stable isotopes, and so, comparison of the effects for different isotopes provides possibility for precise measurement of the Weinberg angle.

description: Σήμερα οι άνθρωποι έχουν να αντιμετωπίσουν αμέτρητες προκλήσεις και να λύσουν έναν σημαντικό αριθμό προβλημάτων. Το πιο σοβαρό από αυτά είναι το φαινόμενο του κοινωνικού αποκλεισμού που συνδέεται με την απομάκρυνσή τους από την κοινωνική πραγματικότητα και οδηγεί στην κατάρρευση του συστήματος. Κάτω από αυτές τις συνθήκες η εκπαίδευση μπορεί να προσφέρει λύση σε αυτό το πρόβλημα μέσα από δραστηριότητες δια βίου μάθησης, ώστε εκείνο που προέχει είναι η αναμόρφωση του εκπαιδευτικού συστήματος προκειμένου να εξασφαλίσουν την κοινωνική συνοχή και τελικά την κοινωνική ισορροπία μέσα από τη συνεχιζόμενη εκπαίδευση.

Ιδιαίτερα επικεντρώνεται στην τοπική κοινότητα της Καλαμαριάς που οδηγεί σε πολύτιμες διαπιστώσεις σχετικά με την ενίσχυση του κοινωνικού κεφαλαίου και την ανάπτυξη του ρόλου του πολίτη μέσα από την κοινωνική σταθερότητα που η εκπαιδευτική σταθερότητα εξασφαλίζει
description: Nowadays, people have to face innumerable challenges and to solve a great number of problems. The most serious of them is the phenomenon of social exclusion which is related to their removal of social reality and leads to the collapse of social system. Under these circumstances education can give solution to this problem through lifelong learning activities so that what comes first is the re-examination of educational system in order to secure social cohesion and finally, social stability through continuing education. This post-graduate effort focuses on the promotion of lifelong learning in local community. Particularly, it is focuses on community of Kalamaria which leads to valuable conclusions concerning the strengthening of social capital and the growth of citizens role through social stability which educational stability secures
The generation of optical emission-line filaments in galaxy clusters

description: Recent data support the idea that the filaments observed in H_alpha emission near the centres of some galaxy clusters were shaped by bulk flows within their intracluster media. We present numerical simulations of evaporated clump material interacting with impinging winds to investigate this possibility. In each simulation, a clump falls due to gravity while the drag of a wind retards the fall of evaporated material leading to elongation of the tail. However, we find that long filaments can only form if the outflowing wind velocity is sufficiently large, 10^8 cm s^-1. Otherwise, the tail material sinks almost as quickly as the cloud. For reasonable values of parameters, the morphological structure of a tail is qualitatively similar to those observed in clusters. Under certain conditions, the kinematics of the tail resemble those reported in Hatch et al.(2006). A comparison of the observations with the numerical results indicates that the filaments are likely to be a few tens of Myrs old. We also present arguments which suggest that the momentum transfer, from an outflowing wind, in the formation of these filaments is probably significant. As a result, tail formation could play a role in dissipating some of the energy injected by a central AGN close to the cluster centre where it is needed most. The trapping of energy by the cold gas may provide an additional feedback mechanism that helps to regulate the heating of the central regions of galaxy clusters and couple the AGN to the ICM.
