Time Series with Tailored Nonlinearities  [PDF]
C. Raeth,I. Laut
Physics , 2015, DOI: 10.1103/PhysRevE.92.040902
Abstract: It is demonstrated how to generate time series with tailored nonlinearities by inducing well- defined constraints on the Fourier phases. Correlations between the phase information of adjacent phases and (static and dynamic) measures of nonlinearities are established and their origin is explained. By applying a set of simple constraints on the phases of an originally linear and uncor- related Gaussian time series, the observed scaling behavior of the intensity distribution of empirical time series can be reproduced. The power law character of the intensity distributions being typical for e.g. turbulence and financial data can thus be explained in terms of phase correlations.

Journal of Food Technology , 2013,
Abstract: The pulp of calabash fruit (Crescentia cujete) has been studied for its nutritive and anti-nutritive compositions in both the wet and dry samples. The values of the ash; 3.74% (dry), ether extract; 4.38% (wet) crude protein; 7.67% (wet) and 10.01% (dry), crude fibre; 4.88% (dry), carbohydrate; 15.65% (wet) and 68.13% (dry) and dry matter; 31.32% (wet) and 87.48% (dry) are quite reasonable for fruits. Both the wet and dry samples have very high concentrations of the mineral elements. Sodium (Na) has the highest values of 3.20% (wet) and 0.32% (dry), while calcium has the least values of 0.12% (wet) and 0.06% (dry). The pulp has very high values of Thiamin; 1.50 g g 1 (wet) and 0.93 g g 1 (dry). Both the wet and dry pulp samples have reasonable values of phytochemicals and are free from HCN toxicity. The pulp can make useful contributions to human nutrition and health.

Pakistan Journal of Nutrition , 2010,
Abstract: Oak (Quercus sp.) leaves and branches is an important source of forage in the north-west of Iran, during winter season, when the pasture herbages are not available, but the nutritive value of this forage is not well known. In this study nutritive value of three species of oak tree leaves: Quercus persica, Q. infectoria and Q. libani were assessed by chemical analysis and in situ method. The chemical composition (g/kg DM basis) of the above species, respectively were as follow; 951, 927, 946, Organic Matter (OM); 115, 92, 123, Crude Protein (CP); 532, 540, 512, Neutral Detergent Fiber (NDF); 317, 300, 331, Acid Detergent Fiber (ADF); 98, 103, 95, lignin (ADL); 78, 115, 104, total phenols; 73, 109, 100, Total Tannins (TT); 14, 15, 12, Condensed Tannin (CT) and 46, 87, 62, Hydrolysable Tannin (HT). Protein Precipitable Phenolics (PPP) were respectively 160, 190 and 230 (g/kg total phenols). Rumen liquor taken from three male Ghezel sheep was used to measure the in situ degradability characteristics of oak leaf. The soluble component (a), insoluble but fermentable fraction (b), the potential degradability (a+b) and the Effective Degradability (ED) were higher in Q. persica (p<0.01). There was a strong negative correlation between TT, HT and ED in sheep. The rank order of nutritive value, in terms of chemical composition and in situ degradability were as follows: Q. persica > Q. libani > Q. infectoria.

International Journal of Nephrology , 2011, DOI: 10.4061/2011/940267
Abstract: Consideration of specific pediatric aspects is essential to achieve adequate peritoneal dialysis (PD) treatment in children. These are first of all the rapid growth, in particular during infancy and puberty, which must be accompanied by a positive calcium balance, and the age dependent changes in body composition. The high total body water content and the high ultrafiltration rates required in anuric infants for adequate nutrition predispose to overshooting convective sodium losses and severe hypotension. Tissue fragility and rapid increases in intraabdominal fat mass predispose to hernia and dialysate leaks. Peritoneal equilibration tests should repeatedly been performed to optimize individual dwell time. Intraperitoneal pressure measurements give an objective measure of intraperitoneal filling, which allow for an optimized dwell volume, that is, increased dialysis efficiency without increasing the risk of hernias, leaks, and retrofiltration. We present the concept of adapted PD, that is, the combination of short dwells with low fill volume to promote ultrafiltration and long dwells with a high fill volume to improve purification within one PD session. The use of PD solutions with low glucose degradation product content is recommended in children, but unfortunately still not feasible in many countries. 1. Introduction Peritoneal dialysis (PD) is increasingly applied around the globe; newborns and even preterm children with a body weight of as little as 1500?g are meanwhile included in the chronic PD program. Whereas initial prognosis is often determined by acute comorbidities, such as neonatal complications and diseases associated with hereditary syndromes, long-term outcome is essentially determined by adequate control of uremia-related sequelae, mainly bone mineral disease and cardiovasculopathy [1]. Dietary and life style changes are difficult to procure. Individually tailored, optimized PD regimes, considering specific pediatric aspects, are therefore essential to achieve an improved long-term outcome of patients with pediatric onset of dialysis. 2. Specific Pediatric Aspects A salient feature of children is the rapid somatic and psychomotor development in the first years of life and during puberty. Growth rate reaches 20?cm during the first and 15?cm during the second year of life. Body length is doubled within four years. This requires careful and repeated adaptation of the PD regime to body size and of protein, energy, and mineral supply. Total body calcium content is 25?g in newborns and increases to 1?kg until adulthood. Insufficient calcium

Abstract: The nutritive value of 25 edible Orthoptera in Mexico is shown. Protein content ranges from 43.93% to 77.13% (mix of Edible Acrididade of Puebla). Fat percentage goes from 4.22% to 34.21%. Richest species in ashes were Arphia fallax S., Sphenarium histrio G. and Sphenarium purpurascens Ch. with 16.5%. Energy contribution varies from 14.05 kJ to 21.88 kJ. Their amino acids profile was compared with the WHO/FAO/UNU Pattern (1985). The total quantity of es-sential amino acids that all insects species provides was superior to those signaled in the pattern. The highest quantity (53.60 g) was for Sphenarium histrio G. Chemical score goes from 50% to 88%. In vitamins, the highest value in Thiamine and Riboflavine was for Sphenarium magnum M., in Niacine for Sphenarium borrei B., in vitamin C and for vitamin D Acheta domestica L., and in Vitamin A for Periplaneta americana L. In minerals, all species were very rich in magnesium. All the edible orthopterans results were compared with those of the most conventional mexican foods used to obtain proteins. The quantity and quality of the nutrients that these edible orthopterans allows, provides a significant contribution to the nutrition of the peasants who eat them.

Abstract: the use of ensiled sugarcane has been increased lately in brazil due to the benefits that this technique represents. the objective of this study was to evaluate the effects of chemical additives on the nutritive value of sugarcane silages. the trial was carried out in a completely randomized experimental design with four replicates per treatment. the following additives were applied onto the fresh forage before ensiling: l. buchneri, lime or limestone, 1.0 and 1.5% (wet basis) each, and gypsum 1.0% (wet basis), all of them diluted into 40 l of water per ton of fresh weight of forage. the analyzed variables were: ash, crude protein, neutral detergent fiber, acid detergent fiber and organic and dry matter digestibility. the addition of lime or limestone before ensiling produced silages with higher nutritive value compared to all other treatments, due to the increase of the ash content and dry matter and organic digestibility, and also by reducing the fiber content. the crude protein content range was similar to the values observed in the fresh forage. the treatments containing l. buchneri or gypsum were ineffective in improving the nutritive value of sugarcane silages and became similar to the control silages. treatment containing lime or limestone improved the nutritive value of the sugarcane silage.

Physics , 2011, DOI: 10.1103/PhysRevA.85.063611
Abstract: We show that, in contrast to immediate intuition, Anderson localization of noninteracting particles induced by a disordered potential in free space can increase (i.e., the localization length can decrease) when the particle energy increases, for appropriately tailored disorder correlations. We predict the effect in one, two, and three dimensions, and propose a simple method to observe it using ultracold atoms placed in optical disorder. The increase of localization with the particle energy can serve to discriminate quantum versus classical localization.

Abstract: Purpose/Objectives: This study was conducted to assess the nutritive value of Libyan airline breakfast in comparison with the Recommended Dietary Allowances (RDA) and to conduct sensory evaluation of selected items on board the flights. Design/Methodology: Food samples were collected from the catering department of Benina International airport, Benghazi, Libya for a period of two months and nutritive value was calculated. A self administered questionnaire prepared on the basis of the Hedonic scale was used for inflight sensory evaluation of selected snacks. Findings: The results on nutritive value of snacks revealed higher amounts of energy, carbohydrates, saturated fat and sodium in comparison to the RDA when the full day’s meal was considered. Micronutrients such as vitamins A, E, C and folic acid fell short of RDA. Sensory evaluation revealed that a majority of the travelers disliked most of the breakfast items except juice. Practical implications: The airline needs to improve the micronutrient content of snacks, simultaneously reducing the total energy and sodium content and replacing saturated fat to prevent health risks to regular airline passengers. Also palatability need not be compromised in light of safety of food items served.
