Abstract:

It is largely assumed that the teleost retina shows continuous and active proliferative and neurogenic activity throughout life. However, when delving into the teleost literature, one finds that assumptions about a highly active and continuous proliferation in the adult retina are based on studies in which proliferation was not quantified in a comparative way at the different life stages or was mainly studied in juveniles/young adults. Here, we performed a systematic and comparative study of the constitutive proliferative activity of the retina from early developing (2 days post-fertilisation) to aged (up to 3–4 years post-fertilisation) zebrafish. The mitotic activity and cell cycle progression were analysed by using immunofluorescence against pH3 and PCNA, respectively. We observed a decline in the cell proliferation in the retina with ageing despite the occurrence of a wave of secondary proliferation during sexual maturation. During this wave of secondary proliferation, the distribution of proliferating and mitotic cells changes from the inner to the outer nuclear layer in the central retina. Importantly, in aged zebrafish, there is a virtual disappearance of mitotic activity. Our results showing a decline in the proliferative activity of the zebrafish retina with ageing are of crucial importance since it is generally assumed that the fish retina has continuous proliferative activity throughout life.

Abstract:

Abstract Juvenile idiopathic arthritis (JIA) is the most common paediatric rheumatic disease. It represents a group of heterogenous inflammatory disorders with unknown origin and is a diagnosis of exclusion in which imaging plays an important role. JIA is defined as arthritis of one or more joints that begins before the age of 16 years, persists for more than 6 weeks and is of unknown aetiology and pathophysiology. The clinical goal is early suppression of inflammation to prevent irreversible joint damage which has shifted the emphasis from detecting established joint damage to proactively detecting inflammatory change. This drives the need for imaging techniques that are more sensitive than conventional radiography in the evaluation of inflammatory processes as well as early osteochondral change. Physical examination has limited reliability, even if performed by an experienced clinician, emphasising the importance of imaging to aid in clinical decision-making. On behalf of the European Society of Musculoskeletal Radiology (ESSR) arthritis subcommittee and the European Society of Paediatric Radiology (ESPR) musculoskeletal imaging taskforce, based on literature review and/or expert opinion, we discuss paediatric-specific imaging characteristics of the most commonly involved, in literature best documented and clinically important joints in JIA, namely the temporomandibular joints (TMJs), spine, sacroiliac (SI) joints, wrists, hips and knees, followed by a clinically applicable point to consider for each joint. We will also touch upon controversies in the current literature that remain to be resolved with ongoing research. Key Points • Juvenile idiopathic arthritis (JIA) is the most common chronic paediatric rheumatic disease and, in JIA imaging, is increasingly important to aid in clinical decision-making. • Conventional radiographs have a lower sensitivity and specificity for detection of disease activity and early destructive change, as compared to MRI or ultrasound. Nonetheless, radiography remains important, particularly in narrowing the differential diagnosis and evaluating growth disturbances. • Mainly in peripheral joints, ultrasound can be helpful for assessment of inflammation and guiding joint injections. In JIA, MRI is the most validated technique. MRI should be considered as the modality of choice to assess the axial skeleton or where the clinical presentation overlaps with JIA.

Abstract:

Objective: Musculoskeletal sonography (MSKS) is increasingly being used in the setting of juvenile idiopathic arthritis (JIA). The purpose of this narrative review was to describe the role of sonography in JIA and outline strategies for operators of pediatric MSKS. Methods: A literature review through multiple medical databases was conducted by restricting the search to medical subject headings (MeSH). Peer-reviewed English-language articles from 2007 to 2018 were included, which focused the on common sonographic findings of JIA. Results: Twenty-six articles were selected for inclusion in the study after a complete reading. Many studies aimed to address the validity of sonographic techniques in the assessment of JIA, but few studies discussed the specific sonographic appearances of JIA, scanning pitfalls, and appropriate imaging techniques. Conclusion: MSKS reveals subclinical manifestations of arthropathy, but the true value of detecting subclinical disease is not well understood. MSKS is limited in the evaluation of articular cartilage thinning and bony erosions. Responsiveness of MSKS in JIA remains to be formally assessed with higher quality studies.

Abstract:

Hepatocyte nuclear factor 1β (HNF1β)-associated disease is a rare autosomal dominant disease caused by various mutations in the HNF1β gene coding the hepatocyte nuclear factor 1β. HNF1β is a transcription factor that is critical for the development of kidney urogenital tract, pancreas, liver, brain, and parathyroid gland. Renal phenotype or HNF1β- nephropathy appeared to be extremely heterogenic: multicystic renal dysplasia, renal hypoplasia, unilateral renal agenesis, horseshoe kidney, atypical familial juvenile hyperuricemic nephropathy, urinary tract malformations and tubular dysfunction. Extrarenal phenotype of HNF1β-associated disease could be maturity-onset diabetes of the young (MODY), pancreatic atrophy and exocrine pancreatic dysfunction, elevated liver enzymes, neonatal cholestasis, congenital abnormalities of the genital tract, hyperparathyroidism, neurological symptoms. The multisystem phenotype makes clinical verification of the diagnosis extremely difficult. In this article, we present a clinical observation of a child with HNF1β – associated disease. The first clinical presentation of HNF1β-associated disease was ultrasound changes in the kidneys (hyperechogenic kidneys?), which were detected by prenatal ultrasonography in pregnancy. Renal ultrasound revealed polycystic kidney disease in the first days of life and bilateral medullary nephrocalcinosis by the age of three. The clinical examination showed a reduced renal function and developed Fanconi syndrome (glycosuria, low molecular proteinuria, hypophosphatemia, aminoaciduria, hyperuricosuria) in the first year of life. Also the child had a non-constant asymptomatic elevation of liver enzymes, hyperparathyroidism, osteoporosis. The diagnosis was confirmed by the results of next generation sequencing which revealed novel heterozygous mutation in exon 4 of the HNF1b gene (chr17: 36091813C>T), p.Cys273Tyr (c.818G>A). The identified mutation was validated by Sanger sequencing. Validation by Sanger sequencing did not reveal a chr17: 36091813C>T mutation in parents, which suggested the appearance of a mutation in the child de novo.

We deal here with an exactly solvable N-nucleon system that has been used to mimic typical features of quantum many-body systems. There is in the literature some controversy regarding the possible existence of a quantum phase transition in the model. We show here that an appeal to a suitable statistical quantifier called thermal efficiency puts an end to the controversy.

Full text

Abstract:

The Buff-banded Rail Gallirallus philippensis is not uncommon in favourable parts of its range but its elusive nature makes it difficult to study and, in particular, development of chicks to attainment of juvenile plumage and adult size is incompletely reported. In the northern suburbs of Canberra, Australian Capital Territory, planned storm-water management has resulted in the formation of wetlands, watercourses and pools, an ideal environment for rails and crakes. Physical and behavioural development could therefore be followed from opportunistic observations and photography of three broods of chicks, from black downy hatchlings to fully fledged juveniles, at Forde Creek in 2014–2015. The first feathers were visible on the fourth day. All the down had been replaced withfeathers by around the third week, by which time the juveniles were about half the size of the adults. The juvenile Rails took another 3 weeks to fully develop the distinctive juvenile plumage patterning, similar to but duller than in adults, and by this time they were the same size as the adults. Although the rate of plumage development is broadly consistent with the literature, the growth rate was slower than the widely quoted figure of adult size being reached in 3 weeks. Observations over 107 days in summer 2014–autumn 2015 provided an opportunity to observe the behaviour of dependent chicks and adults as the chicks developed into juveniles and gained independence.

Abstract:

We investigated the nuclear quadrupole coupling of the 11B and 10B nuclei in fluorodihydroxy borane, BF(OH)2. An analysis of the hyperfine splittings resulted in the coupling constants %aa = -1.414(11) MHz, %bb = - 1.206(11) MHz, %cc = 2.620(11) MHz for 11B and %aa = -2.872(67) MHz, y M = -2.525(69) MHz, %cc = 5.397(69) MHz for 10B. From these constants the ratio r of the quadrupole moments r = Q(10B)/Q(11B) = 2.051 (44) could be derived and compared to data taken from the literature

Abstract:

Abstract Through the use of axisymmetric 2D hydrodynamic simulations, we further investigate laterally propagating flames in X-ray bursts (XRBs). Our aim is to understand the sensitivity of a propagating helium flame to different nuclear physics. Using the Castro simulation code, we confirm the phenomenon of enhanced energy generation shortly after a flame is established by adding 12C(p, γ)13N(α, p)16O to the network, in agreement with the past literature. This sudden outburst of energy leads to a short accelerating phase, causing a drastic alteration in the overall dynamics of the flame in XRBs. Furthermore, we investigate the influence of different plasma screening routines on the propagation of the XRB flame. We finally examine the performance of simplified spectral deferred correction, a novel approach to hydrodynamics and reaction coupling incorporated in Castro, as an alternative to operator splitting.

Abstract:

Three-body cluster-model calculations are performed for the new types of big-bang nucleosynthesis (BBN) reactions that are calalyzed by a supersymmetric (SUSY) particle stau, a scalar partner of the tau lepton. If a stau has a lifetime ≳ 103s, it would capture a light element previously synthesized in standard BBN and form a Coulombic bound state. The bound state, an exotic atom, is expected to induce various reactions, such as (αX-) + d → 6 Li + X-, in which a negatively charged stau (denoted as X-) works as a catalyzer. Recent literature papers have claimed that some of these stau-catalyzed reactions have significantly large cross sections so that inclusion of the reactions into the BBN network calculation can change drastically abundances of some elements, giving not only a solution to the 6 Li -7 Li problem (calculated underproduction of 6 Li by ~ 1000 times and overproduction of 7 Li +7 Be by ~ 3 times) but also a constraint on the lifetime and the primordial abundance of the elementary particle stau. However, most of these literature calculations of the reaction cross sections were made assuming too naive models or approximations that are unsuitable for those complicated low-energy nuclear reactions. We use a few-body calculational method developed by the authors, and provides precise cross sections and rates of the stau-catalyzed BBN reactions for the use in the BBN network calculation.

Abstract:

Quantum computing (QC) has emerged as a promising technology, and is believed to have the potential to advance nuclear and high energy physics (NHEP) by harnessing quantum mechanical phenomena to accelerate computations. In this paper, we give a brief overview of the current state of quantum computing by highlighting challenges it poses and opportunities it offers to the NHEP community. Noisy intermediate-scale quantum (NISQ) computers, while limited by imperfections and small scale, may hold promise for near-term quantum advantages when coupled with co-designed quantum algorithms and special-purpose quantum processing units (QPUs). We explore various applications in NHEP, including quantum simulation, event classification, and realtime experiment control, emphasising the potential of variational quantum circuits and related techniques. To identify current interests of the community, we perform an analysis of recent literature in NHEP related to QC.

Abstract:

Nuclear magnetic resonance is viewed as an important technique for the implementation of many quantum information algorithms and protocols. Although the most straightforward approach is to use the two-level system composed of spin nuclei as qubits, quadrupolar nuclei, which possess a spin greater than , are being used as an alternative. In this study, we show some unique features of quadrupolar systems for quantum information processing, with an emphasis on the ability to execute efficient quantum state tomography (QST) using only global rotations of the spin system, whose performance is shown in detail. By preparing suitable states and implementing logical operations by numerically optimized pulses together with the QST method, we follow the stepwise execution of Grover's algorithm. We also review some work in the literature concerning the relaxation of pseudo-pure states in spin systems as well as its modelling in both the Redfield and Kraus formalisms. These data are used to discuss differences in the behaviour of the quantum correlations observed for two-qubit systems implemented by spin and quadrupolar spin systems, also presented in the literature. The possibilities and advantages of using nuclear quadrupole resonance experiments for quantum information processing are also discussed.

In order to describe their properties we resort to a variety of theoretical treatments which include, lattice QCD, constituent models, AdS/QCD methods, and QCD sum rules. The review is supposed to be an informed guide to the literature. Therefore, we do not discuss in detail technical developments but refer the reader to the appropriate references.

The frequency dependence of the spin-lattice relaxation time T1 was measured at three temperatures near one of the Zeeman-tunneling level matching resonances for pentamethylbenzene. These measurements are correlated with 71 temperature dependence data from the literature. It is shown that the frequency dependence of the Zeeman-torsion coupling time cannot be explained in terms of the semiclassical perturbation theory using time correlation functions. A three bath polarization transfer model is also employed and the applicability of both models discussed. Zeeman-torsion coupling is further investigated using a saturation sequence and the results are compared with the predictions of the three bath polarization transfer model.

Abstract We present fitting formulae for the dynamical ejecta properties and remnant disk masses from the largest to date sample of numerical relativity simulations. The considered data include some of the latest simulations with microphysical nuclear equations of state (EOS) and neutrino transport as well as other results with polytropic EOS available in the literature. Our analysis indicates that the broad features of the dynamical ejecta and disk properties can be captured by fitting expressions, that depend on mass ratio and reduced tidal parameter. The comparative analysis of literature data shows that microphysics and neutrino absorption have a significant impact on the dynamical ejecta properties. Microphysical nuclear EOS lead to average velocities smaller than polytropic EOS, while including neutrino absorption results in larger average ejecta masses and electron fractions. Hence, microphysics and neutrino transport are necessary to obtain quantitative models of the ejecta in terms of the binary parameters.

Abstract The power system, including the power transmission, distribution, and support system, is one of the largest and most complex systems established by humans. In addition to the normal considerations of power plants on board, the design of nuclear power merchant ships is also based on the need for uninterruptible power supplies. Based on the relevant data of the nuclear power ship “Savannah,” the qualitative and quantitative analysis is performed using the fault tree analysis method to analyze the reliability of its power system. The probability of basic events in certain accident conditions is evaluated according to the literature survey. In addition, this study also examines the common cause failure of diesel generators in the power system, as well as the analysis of sensitivity and importance of basic events. The installation of primary, auxiliary, and emergency power stations, the use of automated equipment for generator synchronization and power conversion, and the application of special internal communication and alarm systems unique to nuclear-powered ships can effectively eliminate the possibility of complete power outages for Savannah.

Our study reveals that different technical parameters do not alter significantly the structure of fractional yields. The cluster decay half-lives of different clusters lie within ±10% for different Fermi density parameters and nuclear radii and, therefore, justify the current set of parameters used in the literature for the calculation of cluster decays.

Abstract Spin-polarized β-active 23Ne (T1/2 = 37.2s) nuclei were created by capture of polarized cold neutrons in solid and liquid neon. The angular asymmetry of the β-radiation was used to monitor the nuclear polarization. From nuclear magnetic resonance curves the value for the dipole moment |μ(23Ne)| = 1.079(1) n.m. (uncorrected) was obtained which is more precise than the literature value. Comparing the measured spin-lattice relaxation rates with those of stable 21Ne the nuclear quadrupole moment of 23N e was determined. It agrees with a shell model calculation. The feasibility of 23Ne-β-NMR for investigations in condensed rare gases in demonstrated.

Abstract:

We have recently presented a new non-relativistic nuclear energy density functional which is constructed, not as usual, from an effective density dependent nucleon-nucleon force but directly introducing in the functional results from microscopic nuclear and neutron matter Bruckner G -matrix calculations at various densities. We add a purely phenomenological finite range part to account for surface properties. We take from the literature a density dependent zero range force to describe the pairing correlations. We find that only four to five adjustable parameters, spin-orbit included, suffice to reproduce nuclear binding energies and radii to the same accuracy as those obtained with some of the best effective forces for both spherical and deformed nuclei. The deformation properties of this new functional are in excellent agreement with the results computed using the Gogny D1S force.

Abstract:

Locoregional recurrences occurring in every second patient with locally advanced head and neck tumors are the main cause of treatment failures. The primary treatment modality for patients with the relapsed disease is surgery. However, the resection of head and neck cancer recurrences is effective for one-third of patients only because of the complex spatial anatomical localization of the relapses and the wide spread of the tumor. In most cases the use of different combinations of chemotherapy and immunotherapy can increase life expectancy by up to one year. In order to extend the lifespan of patients for a longer period researchers add to look for new, more effective treatments. Reirradiation improves local control of the tumor, however due to the use of large irradiated of the targets and high radiation doses delivered in the primary irradiation does not leave a tolerance reserve for surrounding healthy tissues, it is a cause of higher incidence of complications. That is why reirradiation has been used quite rarely. However, in recent years radiotherapy has made a big step in technical development and new radiotherapy techniques have appeared. The advanced treatment allows to reduce the radiation dose delivering to healthy tissues and the risk of late radiation-induced complications development. The review presents analysis published research on the effectiveness of head and neck tumors reirradiation with various radiotherapy techniques available in Russian and foreign scientific literature, as well as physico-dosimetric comparison of the methods and parametrization of reirradiation.

Abstract:

Fission fragments exhibit large angular momenta J, which constitutes a challenge for fission models to fully explain. Systematic measurements of isomeric yield ratios (IYR) are needed for basic nuclear reaction physics and nuclear applications, especially as a function of mass number and excitation energy. One goal is to improve the current understanding of the angular momentum generation and sharing in the fission process. To do so, one needs to improve the modeling of nuclear de-excitation. In this work, we have used the TALYS nuclear-reaction code to relax excited fission fragments and to extract root-mean-square (rms) values of initial spin distributions, after comparison with experimentally determined IYRs. The method was assessed by a comparative study on 252Cf(sf) and 235U(nth,f). The results show a consistent performance of TALYS, both in comparison to reported literature values and to other fission codes. A few discrepant Jrms values were also found. The discrepant literature values could need a second consideration as they could possibly be caused by outdated models. Our TALYS method will be refined to better comply with contemporary sophisticated models and to reexamine older deduced values in literature.

Abstract:

The past three decades of investigation on nuclear physics and pulsar astrophysics have seen gradual recognition that elastodynamic approach to the continuum mechanics of nuclear matter provides proper account of macroscopic motions of degenerate Fermi-matter constituting interior of the nuclear material objects, the densest of all known today. This paper focuses on one theoretical issue of this development which is concerned with oscillatory behavior of a viscoelastic solid globe in the regime of quasistatic, force-free, noncompressional oscillations less investigated in the literature compared to oscillations in the regime of standing shear waves. We show that in this case the problem of computing frequency and lifetime of spheroidal and torsional modes of nonradial shear vibrations damped by viscosity can be unambiguously resolved by working from the energy balance equation and taking advantage of the Rayleigh's variational method. The efficiency of this method is demonstrated by solid globe models of nuclear physics and pulsar astrophysics dealing with oscillations of a spherical mass of a viscoelastic Fermi-solid with homogeneous and nonhomogeneous profiles of the bulk density, the shear modulus, and the shear viscosity.

Abstract:

This paper aims to present some results on nonlinear dynamics in active nanostructures as lasers with quantum wells and erbium doped laser systems using mathematical models, methods, and numerical simulations for some related high energy physics phenomena. We discuss nonlinear dynamics of laser with quantum wells and of fiber optics laser and soliton interactions. The results presented have important implications in particle detection and postdetection processing of information as well as in soliton generation and amplification or in the case that these simulations are thought to be useful in the experiments concerning the high energy particles. The soliton behaviour as particle offers the possibility to use solitons for better understanding of real particles in this field. The developed numerical models concerning nonlinear dynamics in nanostructured lasers, erbium doped laser systems, the soliton interactions, and the obtained results are consistent with the existing data in the literature.

Abstract:

The techniques of quadrupole-interaction nuclear-orientation and quadrupole-interaction-resolvedNMR on oriented nuclei were applied to radioactive 111In (T1/2 = 2.8 d), 198Au(T1/2= 2.7 d) and 199Au (T1/2 = 3.1 d), mass-separator-implanted into single crystals of hep Coand hep Gd. For 111InGd the quadrupole interaction was observed via the broadening of theresonance and the dependence of the effective quadrupole interaction on the angle θbetween thec-axis of the single crystal and the direction of magnetization. For 198AuGd the large electric fieldgradient known from the literature could not be confirmed. For 198AuCo and 199AuCo thequadrupole substructure has been resolved, and the electric field gradient of Au in hep Co was determined to be -0.84(4) x 1017V/cm2. The magnetic hyperfine fields of Au in hep and fee Codiffer by about 20%. These experiments have shown that hep Co may be a good host matrix forthe determination of the quadrupole interaction of heavy radioactive nuclei with resonanceprecision.

Abstract:

Despite recent advances in radiation therapy, osteoradionecrosis remains a common and severe complication of radiation therapy in patients with head and neck cancer. Modern methods of treatment are developed with regard to the disease severity and pathophysiology complexity, as well as theories of the osteoradionecrosis development. The following theories of osteoradionecrosis pathophysiology are currently considered: "radiation-induced osteomyelitis", "hypoxic, hypocellular, hypovascular" and "fibroatrophic". Prior to radiation therapy, the patient is provided with restorative dental treatment and radiation therapy planning. Treatments range from conservative «watch and wait» to more radical surgical interventions. Currently, there is no approved standard for the care of osteoradionecrosis patients, however, the activity in this direction is underway. Currently state-of-the-art treatment strategies are available with limited evidence. The review aims to assess the literature on osteoradionecrosis of the jaw with an emphasis on available treatment options.

By employing a pseudoorthonormal coordinate-free approach, the Dirac equation for particles in the Kerr–Newman spacetime is separated into its radial and angular parts. In the massless case to which a special attention is given, the general Heun-type equations turn into their confluent form. We show how one recovers some results previously obtained in literature, by other means.

Abstract:

A recently developed relativistic theory for nuclear matter, which shows consistency with the concept of naturalness and conservation of chiral symmetry, is applied to the description of the Okamoto–Nolen–Schiffer anomaly. The results of our study show significant improvements in the description of the anomaly when compared to the corresponding results of other authors. In particular, our predictions for the Okamoto–Nolen–Schiffer anomaly include the known anomalous growth, namely that the anomaly not necessarily grow with the nuclear mass, since the anomaly is lower, for instance, for the nuclei 39 C and 39 K when compared to the 17 F and 17 O nuclei. As far as we know, this trend was not described by any other model found in the literature.

Abstract:

Background: Ovarian granulosa cell tumors that originate from the sex cord-stromal cells represent 2% to 5% of all ovarian cancers. These tumors constitute two subgroups according to their clinical and histopathological features: juvenile granulosa cell tumors (JGCT) and adult granulosa cell tumors (AGCT). Granulosa cell tumor (GCT) is considered to be a low-grade malignancy with a favorable prognosis. Methods: This case series includes four patients who admitted to our university hospital and had an MRI examination within 5 years. Results: The histopathological subtype of granulosa tumor was the adult type in 3 patients and juvenile type in 1 patient. Even though its extremely rare, bone metastases were present in one of our patients. Liver metastases were also detected in one patient. The MRI examination of tumors revealed a heterogeneous solid mass that contained cystic components in 3 patients. In one of our patients, the tumor had a multiseptated cystic feature, and all of the tumors were ovoid or round with smooth margins. T1 signal hyperintensity, not suppressed on fat saturation sequences, observed in our 3 patients, which represents its hemorrhagic content. Conclusion: Even though granulosa cell tumor shows a wide spectrum in terms of tumor appearance, some common findings have been shown and especially a hemorrhagic content could be a clue for us. The tumor is known to have a good prognosis, but it may have an unpredictable clinical course, so close follow-up has a great importance.

Antecedent history, clinical features and thyroid function tests were consistent with long-standing juvenile hypothyroidism with documented clinical response to thyroxine replacement therapy.Contribution: Typical clinical and radiological features of the syndrome are reported, which helps in the early diagnosis and management, henceforth avoiding the associated complications.
