Non-Markovian dynamics of clusters during nucleation

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Most theories of homogeneous nucleation are based on a Fokker-Planck-like description of the behavior of the mass of clusters. Here we will show that these approaches are incomplete for a large class of nucleating systems, as they assume the effective dynamics of the clusters to be Markovian, i.e., memoryless. We characterize these non-Markovian dynamics and show how this influences the dynamics of clusters during nucleation. Our results are validated by simulations of a three-dimensional Ising model with locally conserved magnetization.

Information of a qubit interacting with a multilevel environment

Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider the interaction of a small quantum system (a qubit) with a structured environment consisting on many levels. The qubit will experience a decoherence process, which implies that its initial information will be transferred to the environment. We investigate how this information is distributed on a given subset of levels as a function of its size, using the mutual information between both entities, in the spirit of the partial information plots studied by Zurek. In this case we observe some differences, which arise from the fact that we are partitioning just one quantum system, and not a collection of them. However some similar features, like a redundancy (in the sense that a given amount of information is shared by many subsets), which increases with the size of the environment, are also found here.

description: The article presents models for managing a light industry enterprise, as well as an experimental implementation of one of them. These models are formed based on approaches to light industry enterprise management and mathematical programming problems. Experimental implementation is presented considering the specifics of the obtained models. For the analysis of the enterprise, system-target and process approaches are used, based on which a conclusion is made about the rational system of the functioning of the enterprise and the tasks that need to be solved in the conditions of the selected system.
An empirical study of locally pseudo-random sequences
Creators: name: Dobell, Alan Rodney
Publisher: name: University of British Columbia
Year: 2012

description: In Monte Carlo calculations performed on electronic computers it is advantageous to use an arithmetic scheme to generate sets of numbers with "approximately" the properties of a random sequence. For many applications the local characteristics of the resulting sequence are of interest. In this thesis the concept of a pseudo-random sequence is set out, and arithmetic methods for their generation are discussed. A brief survey of some standard statistical tests of randomness is offered, and the results of empirical tests for local randomness performed on the ALWAC III-E computer at the University of British Columbia are recorded. It is demonstrated that many of the standard generating schemes do not yield sequences with suitable local properties, and could therefore be responsible for misleading results in some applications. A method appropriate for the generation of short blocks of numbers with approximately the properties of a randomly selected set is proposed and tested, with satisfactory results.

description: Archaeological excavations carried out in different burial sites of north-western Sardinia allowed to observe anatomical variations in ancient skeletal remains. A case of brachymetatarsia, consisting of bilateral abnormal shortness of the fourth metatarsal bone, was detected in an adult female uncovered from the Medieval village of Geridu (Sassari), dated back to the late 13th or the first half of the 14th century; such a rare deformity has a clinical incidence of 0.02% to 0.05% (1). Several anatomical variations were diagnosed in individuals brought to light from the plague cemetery of 16th century Alghero (Sassari). The skeleton of a 9-10-year-old child showed a skull malformation due to premature bilateral closure of the coronal suture, diagnosed as non-syndromic brachycephaly (2). Posterior schisis of the first cervical vertebra, consisting of failure of the midline fusion of the two hemiarches with a small gap, was seen in a male aged 20-30 years; this type of anomaly has a current occurrence of approximately 4%. Occipitalization of the atlas associated with posterior spondiloschisis was observed in a male aged 35-45 years. There is complete fusion of the superior articular facets of the first cervical vertebra with the occipital condyles; this congenital anomaly has a current incidence of 0.14 to 0.75% of the pop- ulation. The small number of published osteoarchaeological cases of anatomical variations makes any report important.

description: The paleonutrition study of ancient people mainly affects the teeth as the outer and the strongest part of the digestive tract, perfused with blood and lymphatic vessels; bring a lot of information that may be useful to understand the nourishment in the past. The aim of this study is to identify possible correlations between the thickness of the enamel and the presence of trace elements as indicators of Palaeolithic diet. The samples came from seven different Sardinian sites dated back to the 3000 bC and 1400 AD. previously subjected to a classical anthropological study, were washed in absolute acetone and rinsed in distilled water. To calculate the amount of enamel on the teeth and its correlation with the dentin, we chose to analyse the samples with micro-CT oriented perpendicular to the occlusal plane with 360° rotation. For the qualitative estimation of trace elements, we used a X-ray fluorescence spectrometer. The study on the thickness of the enamel showed that the total area is approximately uniform and varying the total area, both the area of the enamel and of the dentine proportionally vary. As regards the study of trace elements, the samples showed an almost constant presence of Zinc, Strontium and Manganese due to a diet essentially omnivorous, the enamel appears thicker in the sites where the elements found were Iron, Manganese, Zinc, Copper and Phosphorus reporting to a carnivorous diet. The thickness of the enamel may be affected by the trace elements present in it, so it may be also related to the type of diet. A quantitative study of the elements them- selves could provide, in the near future, more reliable data.

Subjects: Cutaneous melanoma; N-cadherin; Notch1; survival

description: It has been suggested that the invasive and metastatic potential of melanoma cells reflects their ability to undergo epithelial-mesenchymal transition (EMT)-like phenotypic changes (1). Important hallmarks of EMT include the loss of E-cadherin expression and increased expression of the cell adhesion molecule N-cadherin. This cadherin switch leads melanoma cells to lose contact with keratinocytes in the epi- dermis and interact instead with stromal fibroblasts and endothelial cells, thus promoting dermal and vascular melanoma invasion (2). In melanoma, up-regulation of N-cadherin can be induced by the overexpression of the transmembrane receptor Notch1, thus providing a mechanism that underlines increased melanoma cell adhesion, survival, growth, and tumor progression when Notch signaling is activated (3). In this study, the expression of N-cadherin and Notch1 was evaluated by immuno- histochemical analysis in primary cutaneous melanomas and lymph node metastases. First, we evaluated the prognostic impact of high N-cadherin expression on sur- vival in melanoma patients. Second, we correlated the expression of N-cadherin with the full clinicopathological data of patients. Third, we investigated the relationship between the expression of N-cadherin and Notch1. Moreover, N-cadherin expression was evaluated in dysplastic melanocytic nevi and in normal skin. The results will be discussed.

Subjects: Pde2A. Congenital heart disease

description: cAMP and cGMP levels are regulated in a highly specific and stimulus-dependent manner by cyclic nucleotide degrading phosphodiesterases (PDEs). Among the different PDEs, PDE2A is unique because it responds to elevated cGMP levels increasing its cAMP hydrolytic activity. PDE2A is essential for mouse development and Pde2A null mice die in utero (1). Pde2A-/- embryos display a nuchal edema which is associated with congenital heart defects in other mouse models (2). To investigate if the absence of PDE2A is associated with heart defects, macroscopical and microscopical observations of hearts isolated from Pde2A-/- E14.5 embryos were performed. Pde2A-/- hearts appeared enlarged compared to the wild type counterparts and displayed interventricular septum defect, hypertrabeculation, myocardial wall defects and atrial trabeculae loss. Increased apoptosis was detected in specific areas of Pde2A-/- hearts. Compromised expression pattern of critical genes involved in heart development (T-box genes) was observed. RT-PCR analysis revealed that Tbx1, Tbx2, Tbx18 and Tbx20 expression was significantly down-regulated in hearts from Pde2A-/- mice. To investigate whether cAMP might regulate T-box gene expression, fetal cardiomyocytes were treated with a PDE2A inhibitor (EHNA) and the β-adrenergic agonist Isoproterenol (Iso). T-box gene expression was down-regulated in cardiomyocytes treated with EHNA and Iso. Taken together these data suggest that PDE2A activity cannnot be replaced by other phosphodiesterases and its specific function could be the modulation of T-box gene expression during embryonic development. To our knowledge, this is the first time that the genetic deletion of a phosphodiesterase is associated with the establishment of congenital heart defect.

The permanent function

Publisher: name: University of British Columbia

description: Let X be a square matrix of order k over a field F. The permanent of X is given by [Formula omitted] where σ ranges over all the permutations of 1,2,...,k. The original object of this investigation was to characterize those linear maps which leave the permanent unaltered ; that is, per(X) = per(T(X)), all X. Let M[subscript m,n] denote the vector space of all matrices having m rows and n columns with entries taken from F. Fix an integer r, 2 ≤ r ≤ min(m,n). The r-th permanental compound of X ε M[subscript m,n] is defined in an analogous way to the r-th compound of X, and is denoted by P[subscript r](X) ε M[subscript (m over r) [comma] (n over r)]. Subject to mild restrictions on F, the following theorem can be proved. Let T be a linear map on M[subscript m,n] into itself, let S[subscript r] be a non-singular linear map on M[subscript (m over r) [comma] (n over r)] onto itself. Suppose that P[subscript r](T(X)) = S[subscript r](P[subscript r](X)), all X ε M[subscript m,n]. Then for max(m,n) > 2, we have T(X) = DPXQK when m ≠ n ; when m = n , we have either T(X) = DPXQK, allX, or T(X) = DPX'QK, all X. Here P,Q are permutation matrices and D,K are diagonal matrices, of appropriate orders. For the case r = m = n = 2 , there is a certain non-singular linear map B on M[subscript 2,2] onto itself such that BTB(X) = UXV, all X, or BTB(X) = UX'V, all X. Here U,V are non-singular. The original problem arises in the case r = m = n , with S[subscript r] =1, the unit of F.

description: We study the heat kernel for the Laplace type partial differential operator acting on smooth sections of a complex spin-tensor bundle over a generic $n$-dimensional Riemannian manifold. Assuming that the curvature of the U(1) connection (that we call the electromagnetic field) is constant we compute the first two coefficients of the non-perturbative asymptotic expansion of the heat kernel which are of zero and the first order in Riemannian curvature and of arbitrary order in the electromagnetic field. We apply these results to the study of the effective action in non-perturbative electrodynamics in four dimensions and derive a generalization of the Schwinger's result for the creation of scalar and spinor particles in electromagnetic field induced by the gravitational field. We discover a new infrared divergence in the imaginary part of the effective action due to the gravitational corrections, which seems to be a new physical effect.

description: This work deals with soliton solutions of the nonlinear Schroedinger equation with cubic and quintic nonlinearities. We extend the procedure put forward in a recent Letter and we solve the equation in the presence of linear background, and cubic and quintic interactions which are modulated in space and time. As a result, we show how a simple parameter can be used to generate brightlike or darklike localized nonlinear waves which oscillate in several distinct ways, driven by the space and time dependence of the parameters that control the trapping potential, and the cubic and quintic nonlinearities.

description: The evolution model with parallel mutation-selection scheme is solved for the case when selection is accompanied by base substitutions, insertions, and deletions. The fitness is assumed to be either a single-peak function (i.e., having one finite discontinuity) or a smooth function of the Hamming distance from the reference sequence. The mean fitness is exactly calculated in large-genome limit. In the case of insertions and deletions the evolution characteristics depend on the choice of reference sequence.

description: Cystic fibrosis (CF) is a genetic life-shortening condition in Caucasians. Despite being a multi-organ disease, CF is classically diagnosed by symptoms of acute/chronic respiratory disease, with persistent pulmonary infections (Amaral, 2015). CF is caused by mutations in the gene encoding cystic fibrosis transmembrane conductance regulator (CFTR) protein. Inheritance of mutant CFTR alleles results in surface liquid depletion and defective mucociliary clearance leading to pulmonary failure. Defects in CFTR perturb the regulation of many intracellular signaling pathways including the NF-kB pathway causing excessive production of pro-inflammatory mediators. Current CF therapies are directed to delay CF lung damage by restoring CFTR function and controlling abnormal inflammation. However, only few anti-inflammatory drugs are effective for CF treatments (mainly oral corticosteroids and ibuprofen), these drugs have limited beneficial effects in presence of considerable side effects. Flavonoids have been reported as promising anti-inflammatory drugs and some of them seem to act as CFTR direct activators (Amaral, 2015). From this respect, herbal remedies or plant bioactive molecules may be of great interest. To this aim, we tested the anti-inflammatory activity of apolar extracts from the roots of three Peonia species (Paeoniaceae family), namely P. rockii P. ostii and P. lactiflora, on CFTR ΔF508/ΔF508 CuFi1 cells and normal counterpart. The effects of the extracts on intrinsic as well as TNFα-induced inflammation were evaluated by determining IL-8, IL-6 and RANTES production. Further- more, to study the direct effect of the extracts on NF-kB activation, Human Embryonic Kidney cells were used in transient transfection of NF-kB reporter plasmid and NF-kB activity and cytokine productions were also evaluated. Results showed a significant anti-inflammatory activity of all three Peonia extracts with the P. lactiflora being the most effective. Furthermore, we also tested the anti-inflammatory potential of the pure flavonoid naringin in the same model systems. We found that naringin was able to reduce cytokine release through inhibiting the key enzymes of the NF-kB and MAPK/ ERK pathways. Interestingly, preliminary results on spray dried pharmaceutical formulations of this molecule, show that naringin co-sprayed with leucine improves pharmacological activity of the flavonoid neat raw drug.

description: We have recently identified a novel transduction pathway through which Vascular Endothelial Growth Factor (VEGF) controls experimentally induced neoangiogenesis, specifically involving endothelial VEGF receptor subtype 2 and the release of intracellular calcium from NAADP (Nicotinic Acid Adenosine Dinucleotide Phosphate) responsive acidic stores (1). We have now extended this research to an in vivo model of tumor angiogenesis and show that the pharmacologic NAADP inhibitor Ned-19 (2) impairs the vascularization, growth and metastatic spreading of the very aggressive VEGF producing murine tumor, B16 melanoma. In parallel in vitro experiments, we tested whether Ned-19 could directly affect the production of VEGF by the tumor cells, and found that treatment of B16 cells with Ned-19 unexpectedly results in increased VEGF release. These observations indicate that in our model 1) tumor angiogenesis is impaired by Ned-19 even in the presence of increased exposure to VEGF and 2) that NAADP system is active also in B16 melanoma cells. On the basis of this second observation further possible direct effects of Ned-19 on melanoma cell aggressiveness such as growth and invasivity are presently investigated and preliminary results suggest that NAADP system inhibition could potentially represent a twofold therapeutic strategy, directly targeting both tumor angiogenesis and tumor cell growth.

description: Post traumatic shoulder instability is a frequent condition in young active popula- tion. Notwithstanding a lot of data have been collected on capsular-legament lesions and gleno-humeral defects, no data are available on early ultrastructural ostheo-condral damages that are known to be highly associated with the onset of invalidating pathologies, like osteoarthritis (OA). Thus, the mechanisms of joint instability and the identification of which components in the articular complex are primarily affected in instability are of clinical significance, particularly in the light of deepening knowledge on the onset/development of OA. In the present study, biopsies of the articular cartilage and sub-chondral bone were taken from 10 patients (aged 26-40) underwent surgery in Policlinico of Modena. The withdrawals were immediately fixed and embedded for Transmission Electron Microscopy (TEM). The observations were per- formed in tangential, arcuate, and radial layers of the articular cartilage as well as in sub-chondral bone. TEM observations showed that chondrocytes in the superficial layers (i.e. tangential and arcuate) display normal and very well preserved ultrastruc- ture, probably due to synovial liquid supply; otherwise, chondrocytes in the radial layer (not only in calcified but also in the un-calcified one) show various degrees of degeneration, with cytoplasm partially coerced and variously-sized vacuoles, both signs of suffering; occasionally, in the radial layer, chondrocytes with morphological signs of apoptosis or autophagy were also observed. As far as sub-chondral bone is concerned, osteocytes next the deeper calcified cartilage (within 80-100 micra from the cement line) also show evidences of degeneration, while osteocytes more dis- tant from the osteo-chondral border display normal ultrastructure probably due to the vascular bone supply. In all patients of the study, the ultrastructural features of osteo-chondral complex are not depending on age. The present study represents the first ultrastructural investigation of the articular osteo-chondral complex in shoulder instability, evaluating the state of preservation/viability of both chondrocytes and osteocytes throughout the successive layers of the articular cartilage and sub-chondral bone. These preliminary observations are the basis to understand if the early surgical treatment in shoulder instability could avoid the onset of OA.

Retinal microvasculature. A comparison between experimental SEM corrosion casts observations and human in vivo “Angio-OCT” observations

description: In our previous studies on vascular corrosion casts of monkey posterior retina we were able to demonstrate the following points: 1) Capillaries have a laminar distribution. Most vitreal ones are favoured as they are more directly vascularized by side branching arterioles; 2) around the foveal avascular zone, capillaries show a round course and likely function as arteriovenous anastomoses; 3) different layers of capil- laries are connected by side branches of capillaries; 4) peculiar cast imprints at precapillary and capillary branching points are related to smooth muscle cells and pericytes that may perform fine blood flow regulation. Split-spectrum amplitude-decorrelation angiography (SSADA) is an Angio-OCT that provides imaging of the retinal vasculature without the need for intravenous injection of a fluorophore. SSADA makes it possible to follow single blood vessels in different focal planes and indirectly provides data on variation of vessel volume related to blood flow. We compared observation from our previous studies on corrosion casts in Cynomolgus monkeys with images of retinal vasculature as obtained in vivo in man by SSADA. An extremely close relation between monkey and man retinal microvascular anatomy was demonstrated. Both number of layers of capillaries and their connections closely corresponded. Further observations in different conditions may provide definitive information about blood flow regulation sites.

Numerical Solutions of the Isotropic 3-Wave Kinetic Equation

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We show that the isotropic 3-wave kinetic equation is equivalent to the mean field rate equations for an aggregation-fragmentation problem with an unusual fragmentation mechanism. This analogy is used to write the theory of 3-wave turbulence almost entirely in terms of a single scaling parameter. A new numerical method for solving the kinetic equation over a large range of frequencies is developed by extending Lee's method for solving aggregation equations. The new algorithm is validated against some analytic calculations of the Kolmogorov-Zakharov constant for some families of model interaction coefficients. The algorithm is then applied to study some wave turbulence problems in which the finiteness of the dissipation scale is an essential feature. Firstly, it is shown that for finite capacity cascades, the dissipation of energy becomes independent of the cut-off frequency as this cut-off is taken to infinity. This is an explicit indication of the presence of a dissipative anomaly. Secondly, a preliminary numerical study is presented of the so-called bottleneck effect in a wave turbulence context. It is found that the structure of the bottleneck depends non-trivially on the interaction coefficient. Finally some results are presented on the complementary phenomenon of thermalisation in closed wave systems which demonstrates explicitly for the first time the existence of so-called mixed solutions of the kinetic equation which exhibit aspects of both Kolmogorov-Zakharov and equilibrium equipartition spectra.

description: In previous researches severe damages induced by Cadmium (an ubiquitary environmental pollutant whose intracellular oxidative effects are increasingly lethal) exposure in human have been demonstrated. Morphologic effects were observed in Central Nervous System, liver, kidney, placenta. Recently, the involvement of immune system in Cadmium intoxication was demonstrated in mammalians; we, therefore, tried to evidence such effect in a simple model as Apis Mellifera. In this animal the immune system is represented by “fat bodies” which produce proteins active in defense against pathogenic agents. It is important to stress out that a dangerous syndrome causing the collapse of Apis mellifera hives has intensified recently, in Europe and North America. Current research in this field is oriented towards identifying a synergy of contributing factors to the weakening of the hive. In this paper, we aim to determine whether contamination by cadmium may have an immunosuppressive effect on the insect. Preliminary results denote that the heavy metal causes a severe damage in fat bodies, leading to substantial immunodeficiency in exposed bees, suggesting that in polluted areas the hives may have difficulty in dealing with pests and pathogens that threaten them.
