Primordial fluctuations in the warm inflation scenario with a more realistic coarse - grained field

I study a semiclassical approach to warm inflation scenario introduced in previous works. In this work, I define the fluctuations for the matter field by means of a new coarse - grained field with a suppression factor G. This field describes the matter field fluctuations on the now observable scale of the universe. The power spectrum for the fluctuations of the matter field is analyzed in both, de Sitter and power - law expansions for the universe. The constraint for the spectral index gives a constraint for the mass of the matter field in the de Sitter expansion and a constraint for the friction parameter in the power - law expansion for the universe.Comment: 11 pages, no figures (revtex file

Koordinierte Regionalentwicklung: Zielorientierung von Entwicklungsprozessen

Die Forderung nach Koordination ist eine beliebte, weil griffige und plakative Metapher, um sowohl auf Planungsprobleme als auch gleichzeitig auf deren (putative) Lösung hinzuweisen. Doch geht man der Frage nach, was Koordination eigentlich ist und wie denn Koordination gelingen kann, erhält man eher selten überzeugende Antworten. Der vorliegende Band "Koordinierte Regionalentwicklung: Zielorientierung von Entwicklungsprozessen" aus der Reihe "Arbeitsberichte der ARL" versucht, diese Antworten anhand der Betrachtung des Zusammenwirkens zwischen räumlicher Gesamtplanung und teilräumlichen Entwicklungsansätzen vor dem Hintergrund theoretischer Überlegungen zur Herstellung von Handlungskontexten sowie am Beispiel von ILE und LEADER auf Basis von Fallstudienbetrachtungen zu geben.Calls for coordination are a well-loved way of drawing attention to both planning problems and their (putative) solution. However, further exploration of this bold and simple metaphor seldom provides convincing answers as to the actual nature of coordination or how coordination can be successful. "Coordinated regional development: goal orientation of development processes" presents work by the ARL in an attempt to provide such answers. Observation is made of the interaction between spatial master planning and sub-regional development approaches and a background provided by theoretical reflections on the production of contexts of action and by case-studies from the IRD and LEADER programmes

Spatial quantification of vegetation density from terrestrial laser scanner data for characterization of 3D forest structure at plot level

International audiencePrecise description of forest 3D structure at plot level is required for sustainable ecosystem management. However, a detailed structure description from traditional field measurements is tedious. We propose an innovative method to quantify in 3D the spatial distribution of forest structure from terrestrial lidar data. The method rests on the hypothesis that the normalized number of laser returns within a given volume element is proportional to the density of vegetation material inside this volume. The developed model is based on analysis made inside Svoxels (spherical voxels) to compute a spatialized vegetation density index. The model was tested on two different scans of the same plot. The resulting vegetation density index well represents the vegetation structure as observed within the lidar point cloud. Quantitative analyses confirmed a global consistency of the results within and between scans. However, we observed a slight bias in the computed density indexes. It might be mainly explained by occlusions, which cause 1) a slight decrease of the density index with distance and 2) local differences in density index between scans.. Future work will focus on improving our algorithm and correcting biases. These results are promising for the development of quantitative measures of the 3D forest structure

Experimental study of accelerating field distribution optimization in the H-structure with comb holders

We have suggested to perform the tuning the structure accelerating field distribution at the wave similar to H, by changing the inductivity of the holder of a single drift tube. Changing the angle of bend of the adjacent drift tube holders along different sides relatively to the comb holder plane allows one to increase and decrease the field amplitude in the gap between them. The value Rch ≈90 MОhm/m has been obtained for the structure under consideration that is higher than that obtained by known methods of tuning.Пропонується проводити настройку розподілу прискорюючого поля структури на хвилі, аналогічній Н, зміною індуктивності утримувача одиночної трубки дрейфу. Зміна кута повороту утримувачів сусідніх трубок дрейфу в різні боки щодо площини гребінчастого утримувача дає можливість як збільшувати, так і зменшувати амплітуду поля в зазорі між ними. Для структур, що розглядаються, отримано значення Rш ≈ 90 МОм⋅м⁻¹, що більш, ніж при відомих методах настройки.Предлагается проводить настройку распределения ускоряющего поля структуры на волне, аналогичной Н, изменением индуктивности держателя одиночной трубки дрейфа.

Fresh inflation: a warm inflationary model from a zero temperature initial state

A two-components mixture fluid which complies with the gamma law is considered in the framework of inflation with finite temperature. The model is developed for a quartic scalar potential without symmetry breaking. The radiation energy density is assumed to be zero when inflation starts and remains below the GUT temperature during the inflationary stage. Furthermore, provides the necessary number of e-folds and sufficient radiation energy density to GUT baryogenesis can take place near the minimum energetic configuration.Comment: 11 pages, no figures, to be published in Phys.

Improved risk stratification can be achieved by identifying the progression of total plaque area (TPA) using carotid ultrasound, with the risk of CVD events doubling when progression is detected over a 1-year interval. We hypothesize that blood pressure and serum LDL cholesterol control at target values (current clinical guidelines) are insufficient to reduce the progression of atherosclerosis in persons with high CVD risk METHODS AND RESULTS: Prospective, observational study of 742 participants with high cardiovascular risk in a cardiovascular primary prevention program. Two ultrasound measurements of TPA were acquired for each participant for at least one year. We studied only those who maintained a blood pressure below 130/80 mmHg and serum Low-Density Lipoprotein Cholesterol (LDL-C) below 100 mg/dl throughout the study interval (57 participants). Participants with plaque progression of TPA > 5 mm2, were compared to those with TPA changes of 5 mm2 or less (non-progression group) using a multivariable logistic regression controlling for cardiovascular risk factors. We identified TPA progression in 22 of 57 (38.6%) participants. No differences were detected for any covariate when comparing progression versus non-progression. CONCLUSION: Progression of TPA occurs in as many as 38.6% of individuals despite maintaining BP below 130/80 and serum LDL-C below 100 mg/dl. TPA evaluation may help address the limitations of established guidelines for the prevention of CVD events in high-risk individuals.info:eu-repo/semantics/publishedVersionFil: Pérez, Hernán Alejandro.

Hadronization of b→ccˉsb\to c\bar cs

The b -> c cbar s transition is usually believed to hadronize predominantly in Bbar -> X_c Ds(*)- with the Ds(*)- originating from the virtual W. We demonstrate in a variety of independent ways that other hadronization processes cannot be neglected. The invariant mass of cbar s has sizable phase-space beyond m_D+m_K. The rate for Bbar -> D Dbar Kbar X could be significant and should not be ignored as was done in previous experimental analyses. We estimate the number of charmed hadrons per B-decay, n_c, to be about 1.3 to higher accuracy than obtained in previous investigations. Even though n_c is currently measured to be about 1.1, observing a significant Bbar -> D Dbar Kbar X would support n_c of about 1.3. Many testable consequences result, some of which we discuss.Comment: 15 pages, 3 postscript figures encoded into a single .uu fil
