Di fronte alla crisi dell'urbanistica razional-comprensiva, intesa come di passaggio lineare dalla pianificazione all'attuazione, č opportuno riferirsi al pensiero di Musil e Wittegenstein. Entrambi riflettono sulla connessione tra eventi e sulla concatenazione tra ‘cose', non dominate da alcuna legge; la lettura della realtŕ che ne emerge č quella di un patchwork di microcosmi, frutto di risposte parziali e di rappresentazioni alternative degli stati di cose. Lavorare sull'idea di progetto, significa operare sulle categorie a cui essa č principalmente incardinata, quelle di spazio e di tempo, in modo di produrre piů immagini possibili secondo l'approccio concettuale proposto da Florenskij. A partire dalla distinzione tra spazio e spazialitŕ, occorre pensare lo spazio in tutte le sue possibili modalitŕ e tipologie, mettendo in evidenza la sua ‘condizione di possibilitŕ' attraverso una rinnovata percezione degli insediamenti urbani.

Linear automata with translucent letters are studied. These are finite-state acceptors that have two heads that read the input from opposite sides and for which a set of translucent letters is associated with each state. Thus, head 1, which proceeds from left to right, does not necessarily read the first letter of the current tape content, but it skips a prefix that consists of translucent letters only and reads the first letter after that prefix. Analogously, head 2, which proceeds from right to left, does not necessarily read the last letter, but it skips a suffix that consists of translucent letters only and reads the last letter before that. After such a read operation, the head always returns to its corresponding end of the tape. These linear automata with translucent letters are a generalization of the finite-state acceptors with translucent letters that were studied by the authors in B. Nagy and F. Otto [Finite-state acceptors with translucent letters. In BILC 2011, Proc., edited by G. Bel-Enguix, V. Dahl, and A.O. De La Pente, SciTePress, Portugal (2011) 3-13.] It is shown that these linear automata are strictly more expressive than the model with a single head, but that they still only accept languages that have a semi-linear Parikh image. On the other hand, we obtain a characterization for the class of linear context-free trace languages in terms of a specific class of linear automata with translucent letters.

The linear encryption such as Caesar, mono-alphabetic are used to solve the encryption problem in different fields. This module usually encrypts any letter to exact and one corresponding letter. With advanced technologies in computers, these algorithms seem not to be high level secure. This paper proposed a secure encryption algorithm using modified linear encryption by considering the letters’ positions of the plaintext body. Two advantages the proposed algorithm has against traditional ones. First, the cryptography procedures are simple and secure. Secondly, it has higher security because of the non- ingrained nature of poly-alphabetic for substitution. Consequently, the plaintext body is considered as a 2-D matrix, such that, each letter has two coordinates, the ith and jth. These procedures depend on substituting the coordinates of the letter into a linear equation to provide a different substitution letter. The performance of these procedures showed better and robust results by applying the frequency analysis test for this proposed algorithm evaluating.

This study is part of a larger project to generate norms for letter verbal fluency test (VFT) in 3,284 children from nine Latin American countries. The letter VFT (letters M, R, and P) was administered and multiple linear regressions, including age, age2, MPE (mean parental education), MPE2, sex, and interactions were used as predictors. Results showed significant differences across countries for all scores. Age affected scores linearly except for Ecuador (P-letter), in which a quadratic effect was found. Scores increased linearly as a function of MPE, with the exception of Mexico (R-letter), in which a quadratic effect was found. Age by MPE (M- and P-letters), and age by MPE2 (R-letter) interactions were found in Mexico. Sex had an impact on letter R in Cuba, and letter P in Ecuador and Paraguay. Age2 by sex interaction was found in Ecuador (P-letter). These norms will be useful for clinical neuropsychologists in these countries to evaluate their patients’ verbal fluency.

Letter-by-letter (LBL) dyslexia is an acquired reading disorder characterized by very slow reading and a large linear word length effect. This suggests the use of a sequential LBL strategy, in sharp contrast with the parallel letter processing used by normal subjects. Recently, we have proposed that the reading difficulty of LBL dyslexics is due to a deficit in discriminating visually similar letters based on parallel letter processing [Arguin, M., Fiset, S., & Bub, D. Sequential and parallel letter processing in letter-by-letter dyslexia. Cognitive Neuropsychology, 19, 535–555, 2002]. The visual mechanisms underlying this deficit and the LBL strategy, however, are still unknown. In this article, we propose that LBL dyslexic patients have lost the ability to use, for parallel letter processing, the optimal spatial frequency band for letter and word recognition. We claim that, instead, they rely on lower spatial frequencies for parallel processing, that these lower spatial frequencies produce confusions between visually similar letters, and that the LBL compensatory strategy allows them to extract higher spatial frequencies. The LBL strategy would thus increase the spatial resolution of the visual system, effectively resolving the issue pertaining to between-letter similarity. In Experiments 1 and 2, we succeeded in replicating the main features characterizing LBL dyslexia by having normal individuals read low-contrast, high-pass-filtered words. Experiment 3, conducted in LBL dyslexic L.H., shows that, indeed, the letter confusability effect is based on low spatial frequencies, whereas this effect was not supported by high spatial frequencies.

Abstract We study the algorithmic properties of first-order monomodal logics of frames $\langle {\textrm{I}\!\textrm{N}}, \leqslant \rangle $, $\langle {\textrm{I}\!\textrm{N}}, < \rangle $, $\langle \mathbb {Q}, \leqslant \rangle $, $\langle \mathbb {Q}, < \rangle $, $\langle {\textrm{I}\!\textrm{R}}, \leqslant \rangle $, $\langle {\textrm{I}\!\textrm{R}}, < \rangle $, as well as some related logics, in languages with restrictions on the number of individual variables as well as the number and arity of predicate letters. We show that the logics of frames based on $ {\textrm{I}\!\textrm{N}}$ are $\varPi ^1_1$-hard—thus, not recursively enumerable—in languages with two individual variables, one monadic predicate letter and one proposition letter. We also show that the logics of frames based on $\mathbb {Q}$ and ${\textrm{I}\!\textrm{R}}$ are $\varSigma ^0_1$-hard in languages with the same restrictions. Similar results are obtained for a number of related logics.

At MA Darul Ihya Bogor correspondence is an important means of communication. One of the problems in managing letters at the MA Darul Ihya Bogor is the inefficient filing of mail data that still uses a manual system. With the number of incoming letters and outgoing letters each meeting makes a letter that is in the archive so that the search becomes inefficient because not all files are arranged properly. One effort to overcome this problem is to create an in and outgoing mail management information system. The research method used in this study is the method of Lifecycle Development (SDLC) with the Waterfall model. The waterfall model (waterfall) is often also called a linear sequential (linear sequential) model. The results of this study are to make this site-based management information system can facilitate business administration in the process of inputting incoming and outgoing mail data, searching for incoming and outgoing mail data, making reports of incoming and outgoing mail data producing the required information quickly and accurately.

The concept of rooting and renewal in Arabic calligraphy is linked to the calligrapher’s need to show new aesthetic methods, through formations and calligraphic structures based on a single letter. The perceptual vision of the calligrapher, so this research was concerned with studying the rooting and renewal of the rule of the single letter in the formations of Arabic calligraphy in particular, which included four chapters, the first chapter included the research problem, its importance, objectives, limits and definition of its terms. As for the second chapter, it deals with tracing the concept of rooting and renewal and its connection with the artist and the possession of the idea and the ability to technical aesthetic expression, through the one-letter linear formations made by calligraphers, relying on the spatial organization and choosing the appropriate letter for the composition. The analysis concluded with a number of results that were devoted to the fourth chapter, which showed rooting, renewal, acceptance of decorative and different aesthetic formations in structural structures, and investing some characteristics of letters to arrange and divide the linear structure into creative forms and structures.

AbstractBackground:Despite their use in clinical practice, there is little evidence to support the use of therapist written goodbye letters as therapeutic tools. However, preliminary evidence suggests that goodbye letters may have benefits in the treatment of anorexia nervosa (AN).Aims:This study aimed to examine whether therapist written goodbye letters were associated with improvements in body mass index (BMI) and eating disorder symptomology in patients with AN after treatment.Method:Participants were adults with AN (n = 41) who received The Maudsley Model of Anorexia Treatment for Adults (MANTRA) in a clinical trial evaluating two AN out-patient treatments. As part of MANTRA, therapists wrote goodbye letters to patients. A rating scheme was developed to rate letters for structure and quality. Linear regression analyses were used to examine associations between goodbye letter scores and outcomes after treatment.Results:Higher quality letters and letters that adopted a more affirming stance were associated with greater improvements in BMI at 12 months. Neither the overall quality nor the style of goodbye letters were associated with improvements in BMI at 24 months or reductions in eating disorder symptomology at either 12 or 24 months.Conclusions:The results highlight the potential importance of paying attention to the overall quality of therapist written goodbye letters in the treatment of AN, and adopting an affirming stance.

The human ability to recognize a variety of objects, however complex the object, is the special ability that humans possess. Any normal human will have no difficulty in recognizing handwriting objects between an author and another author. With the rapid development of digital technology, the human ability to recognize handwriting objects has been applied in a program known as Computer Vision. This study aims to create identification system different types of handwriting capital letters that have different sizes, thickness, shape, and tilt (distinctive features in handwriting) using Linear Discriminant Analysis (LDA) and Euclidean Distance methods. LDA is used to obtain characteristic characteristics of the image and provide the distance between the classes becomes larger, while the distance between training data in one class becomes smaller, so that the introduction time of digital image of handwritten capital letter using Euclidean Distance becomes faster computation time (by searching closest distance between training data and data testing). The results of testing the sample data showed that the image resolution of 50x50 pixels is the exact image resolution used for data as much as 1560 handwritten capital letter data compared to image resolution 25x25 pixels and 40x40 pixels. While the test data and training data testing using the method of 10-fold cross validation where 1404 for training data and 156 for data testing showed identification of digital image handwriting capital letter has an average effectiveness of the accuracy rate of 75.39% with the average time computing of 0.4199 seconds.

Purpose: Language abilities have long been thought to be weaker in adults who stutter (AWS) compared to adults who do not stutter (AWNS). However, it is unknown whether modality affects language performance by AWS in time pressure situations. This study aimed to examine lexical access and retrieval abilities of AWS in oral and typed modes. Method: Fifteen AWS and 15 well-matched AWNS completed computer-administered letter fluency tasks. Adults were asked to orally produce words that began with one of two letter targets and type words that began with one of two alternate letters. Conditions were counterbalanced across participants. Results: Generalized linear mixed-effects models were evaluated to determine the effects of group (AWS/AWNS), mode (oral/typed), and expressive vocabulary on letter fluency performance. Group predicted letter fluency such that AWS generated fewer items on both the oral and typed letter fluency tasks. Mode did not impact letter fluency results. Expressive Vocabulary Test scores predicted letter fluency similarly in both AWS and AWNS. Conclusions: AWS were not penalized by oral task demands. AWS generated fewer items on the letter fluency tasks regardless of response mode, suggesting that they have weaker lexical access abilities. Furthermore, better expressive vocabulary skills were associated with better letter fluency performance in both groups.

This article applies Distelhorst and Fu’s (2019) typology of citizenship performances to an original sample of 200 online Mayor’s Mailbox letters to examine how scripts of citizenship differ between richer and poorer areas of China. Using a mixed-methods approach, I find that letters in more developed areas are significantly less likely to present the writer as a submissive subject, but no more likely to frame complaints in terms of rights and legality. I also find that many letter writers behave as “constructive citizens” by stressing their interest in helping the authorities improve local governance. These findings challenge linear understandings of the value shift that follows development, and suggest that the focus on contention in the literature on citizenship under authoritarianism overlooks other, more cooperative forms of political participation in consolidated autocracies.

Preschool children begin to represent spoken language in print long before receiving formal instruction in spelling and writing. The current study sought to identify the component skills that contribute to preschool children’s ability to begin to spell words and write their name. Ninety-five preschool children (mean age = 57 months) completed a battery of cognitive, linguistic, as well as print-related measures, including spelling/writing tasks (i.e. letters, words and name). All writing samples were scored using scoring matrices and inter-rater reliability was 90% and above. Hierarchical linear regression was conducted for word spelling, indicating that after controlling for age and IQ, the model of best fit included expressive vocabulary, working memory, blending, letter naming and letter writing ability. Logistic regression was conducted for name writing, indicating that the model that included age, expressive vocabulary, letter naming and letter writing identified preschool children who wrote their name conventionally and those who could not. Letter writing explained unique variance in both word spelling and name writing, and phonological awareness explained unique variance in word spelling only. These findings suggest that different processes underlie word spelling and name writing, supporting the consideration of a dual-route model of children’s early spelling and writing ability.

Every positive integer can be written as a sum of Fibonacci numbers; it can also be written as a (finite) sum of (positive and negative) powers of the golden mean φ. We show that there exists a letter-to-letter finite two-tape automaton that maps the Fibonacci representation of any positive integer onto its φ-expansion, provided the latter is folded around the radix point. As a corollary, the set of φ-expansions of the positive integers is a linear context-free language. These results are actually proved in the more general case of quadratic Pisot units. Résumé: Tout nombre entier positif peut s'écrire comme une somme de nombres de Fibonacci; tout entier peut également s'écrire comme une somme (finie) de puissances (positives et négatives) du "nombre d'or" φ. Nous montrons qu'il existe un automate à deux bandes, fini et lettre-à-lettre, qui envoie la représentation d'un entier en base de Fibonacci sur sa représentation dans la base φ modulo le fait qu'on a replié cette dernière autour du point décimal. On en déduit que l'ensemble des représentations des entiers en base φ est un langage context-free linéaire. Tous ces résultats sont en fait établis dans le cas général où la base considérée est un nombre de Pisot quadratique unitaire.

We study the algorithmic properties of the quantified linear-time temporal logic QLTL in languages with restrictions on the number of individual variables as well as the number and arity of predicate letters. We prove that the satisfiability problem for QLTL in languages with two individual variables and one monadic predicate letter in Σ 11 -hard. Thus, QLTL is Π 11 -hard, and so not recursively enumerable, in such languages. The resultholds both for the increasing domain and the constant domain semantics and is obtained by reduction from a Σ 11 -hard N×N recurrent tiling problem. It follows from the proof for QLTL that similar results hold for the quantified branching-time temporal logic QCTL, and hence for the quantified alternating-time temporal logic QATL. The result presented in this paper strengthens a result by I. Hodkinson, F. Wolter, and M. Zakharyaschev, who have shown that the satisfiability problem for QLTL is Σ 11 -hard in languages with two individual variablesand an unlimited supply of monadic predicate letters.

Although many young children become literate within an environment in which different writing systems exist, there is little research on what children know about different writing systems and how they understand and develop them when they are learning more than one simultaneously. This qualitative study discusses how Korean EFL (English as a Foreign Language) children understand two different writing systems, the Korean alphabet, Hangul, and the Roman alphabet, used for English, within a peer teaching setting. The findings show that they were able not only to discover key orthographic principles which characterise each writing system but also to find similarities and differences between Hangul and English from different points of view: shapes of letters (block shaped vs linear), language units (syllables vs letters) and sound–letter relationship (shallow orthography vs deep orthography). The paper suggests that young children are able to look for key concepts in different writing systems by constructing their own ideas about the principles of reading and writing from an early age as active language learners.

Previous research has explored the development of visual acuity in babies and children, and it has been established that the measured acuities are dependent on the methods used to test visual function. In the present study the developmental trends in crowded versus single letter visual acuities were explored. 343 children 5 to 11 years of age, was tested using Glasgow Acuity Cards (GAC), and a significant correlation between binocular visual acuity and age was found using simple regression analysis (y=0.023x + 0.81, r2 = 0.32). Mean values on crowded visual acuity varied between 0.95 ± 0.6 in 5 year olds to 1.08 ± .09 logMAR in 11 year olds. One way ANOVA confirmed the developmental trend (F(1, 341)=160.45, p<0.0001). In a second study, this result were replicated in a smaller group of fully corrected children (regression analysis showed significant development with age, y=0.025x+.86, r2 = 0.429, one way ANOVA: F(1,72) = 54.11, p<0.0001). The repeatability of the GAC was tested using a test-retest strategy, 6 months apart. A significant improvement of monocular visual acuities at the second retest may be explained, at least in part, by the expected development during this period. A single letter acuity test was constructed by matching GAC optotypes. Fiftyt two emmetropic children (mean age 8.21±1.76 yrs) were tested on both tests. Developmental trends were then compared for single and crowded acuities. Linear regressions were F(1,50)=23.87, p=0.0001, y=0.019x+0.915, r2=0.31 for crowded letters and F(1,50)=5.81, p<0.05, y=0.009x+1.07, r2=0.104 for single letters. Repeated measures ANOVA (test * age) showed reliable differences for both main effects. Single letter acuity was found to display a very slight developmental trend, and was better than crowded acuity. When deciding normal values and cut-off limits, one have to take into consideration which test is being used as normative data will not directly translate from one test to another.

AbstractThis article offers the first large-scale analysis of the interlinked dynamics of integration and belonging based on perceptions of “ordinary” German-speaking migrants in the United States in the nineteenth and twentieth centuries. Our analysis draws on a corpus of over a thousand letters from the North American Letter Collection held at the Forschungsbibliothek Gotha in Germany. Through computer-assisted text analysis, framed by research on transnationalism and immigrant integration, we explore patterns in integration and identities over time. We show how the migrants continuously redefine their identities vis-à-vis their homeland and the host society, and their letters thereby shape the image of the United States and the homeland for their recipients. Our analysis establishes more comprehensively than have previous historical and social science studies that integration into a host society is a non-linear process. Immigrant identities are influenced less by the time they have spent in the receiving country than by critical political events that affect both the country of origin and that of destination. Such events can reactivate migrant's identifications with their homeland. Immigrant networks filter this dual process in that they can facilitate migrants’ integration while also reminding them of people and places left behind.

Linear rankSVM is one of the widely used methods for learning to rank. Although its performance may be inferior to nonlinear methods such as kernel rankSVM and gradient boosting decision trees, linear rankSVM is useful to quickly produce a baseline model. Furthermore, following its recent development for classification, linear rankSVM may give competitive performance for large and sparse data. A great deal of works have studied linear rankSVM. The focus is on the computational efficiency when the number of preference pairs is large. In this letter, we systematically study existing works, discuss their advantages and disadvantages, and propose an efficient algorithm. We discuss different implementation issues and extensions with detailed experiments. Finally, we develop a robust linear rankSVM tool for public use.

Abstract: To argue for the pseudonymity of disputed Pauline letters on the (partial) basis of their disproportional high number of hapax legomena continues to be common practice among New Testament scholars. By means of linear regression analysis, it is shown that only 1 and 2 Timothy use significantly more hapaxes than the undisputed Pauline letters. If, however, proper noun hapaxes, hapaxes taken from citations, and hapaxes which – upon removal of its preposition – have a common lexeme are not taken into consideration, it appears that none of the disputed Pauline letters use significantly more hapaxes than the undisputed Pauline letters.

Relative growth rate (RGR), the relative increase in weight per day, can analyze the effect of environment and nutrition on growth. I examined which of the parameters responding to plant growth scaled according to RGR for lettuce and spinach grown in heated greenhouses in hydroponics with control of the nutrient solution. The experiments for lettuce in 2006–08 included all times of year, high vs. low temperature, and effect of withdrawal of nitrogen. There were four parameters that were significant in multiple linear regression vs. RGR; irradiance divided by leaf area index if it was greater than one, or normalized daily light integral (NDLI), solution temperature, electrical conductivity (EC), and logarithm solution nitrate when it was between 3 and 55 mg·L−1 N. NDLI had the most significant coefficient, but the other parameters had regression coefficients more than three times se. For experiments on spinach in 2009–10, all the parameters mentioned previously were significant in multiple linear regression vs. RGR, except EC. The coefficient for NDLI in spinach was about half the value in lettuce. The coefficients for solution temperature and low nitrate were two and three times that in lettuce. In a third set of experiments on lettuce in 1996–98, solution temperature was the only significant parameter among those mentioned previously. The coefficient for solution temperature was similar to that for regression of lettuce in 2006–08.

Abstract This article examines and compares three grids that were designed to serve explicit moral accounting goals: the calculation and improvement of character. The examples are tables which fall under a broad definition of diagrams. The examples follow another in time, but it is not the article’s intention to suggest a historical lineage between them. Rather, it is the intention to clarify the interplay between grids and the precepts or keys to their use. The first case is the so-called ledger of merit and demerit that was propagated by Yuan Huang, a scholar and bureaucrat of the late Ming-period, who recommended its use for moral improvement in four letters to his son, of which the most famous letter was on the improvement of one’s own fate. The second is Benjamin Franklin’s Art of Virtue, which Franklin in his autobiographical letter to his son equally described as a tool of moral improvement. The third is the so-called moral thermometer, or biometer, a tool developed by the French revolutionary and pedagogical innovator Marc-Antoine Jullien, who described this tool as a moral mirror and compass that would be especially of use in preparing and educating adolescents for their adult lives. All three represent generic methods of producing knowledge about an individual’s (moral) character, knowledge on which the users of these tables could act. Their differences have to do with the perceived relation of moral conduct to other spheres of life, religious, social, and economic, or all of these combined, but also with the different precepts to their use.

AbstractHow well could one predict the growth of a leafy crop from reflectance spectra from the soil and how might a grower manage the crop in the light of those predictions? Topsoil from two fields was sampled and analysed for various nutrients, particle-size distribution and organic carbon concentration. Crop measurements (lettuce diameter) were derived from aerial-imagery. Reflectance spectra were obtained in the laboratory from the soil in the near- and mid-infrared ranges, and these were used to predict crop performance by partial least squares regression (PLSR). Individual soil properties were also predicted from the spectra by PLSR. These estimated soil properties were used to predict lettuce diameter with a linear model (LM) and a linear mixed model (LMM): considering differences between lettuce varieties and the spatial correlation between data points. The PLSR predictions of the soil properties and lettuce diameter were close to observed values. Prediction of lettuce diameter from the estimated soil properties with the LMs gave somewhat poorer results than PLSR that used the soil spectra as predictor variables. Predictions from LMMs were more precise than those from the PLSR using soil spectra. All model predictions improved when the effects of variety were considered. Predictions from the reflectance spectra, via the estimation of soil properties, can enable growers to decide what treatments to apply to grow lettuce and how to vary their treatments within their fields to maximize the net profit from the crop.

We studied the feedforward network proposed by Dandurand et al. ( 2010 ), which maps location-specific letter inputs to location-invariant word outputs, probing the hidden layer to determine the nature of the code. Hidden patterns for words were densely distributed, and K-means clustering on single letter patterns produced evidence that the network had formed semi-location-invariant letter representations during training. The possible confound with superseding bigram representations was ruled out, and linear regressions showed that any word pattern was well approximated by a linear combination of its constituent letter patterns. Emulating this code using overlapping holographic representations (Plate, 1995 ) uncovered a surprisingly acute and useful correspondence with the network, stemming from a broken symmetry in the connection weight matrix and related to the group-invariance theorem (Minsky & Papert, 1969 ). These results also explain how the network can reproduce relative and transposition priming effects found in humans.

Modern fertilization recommendations must optimize crop yield and quality and minimize chances of negative environmental effects due to overfertilization. Data from fertilizer studies can be fitted to several mathematical models to help determine optimum fertilizer rates, but resulting recommendations can vary depending on the model chosen. In this research, lettuce (Lactuca sativa L.) was used as a case study vegetable crop to compare models for estimating fertilizer N requirements. Greenhouse studies were conducted with `South Bay' and `Sierra' cultivars of crisphead lettuce to measure yield response to applied N. Individual plants were grown in pots and received six rates of N (0.0, 0.2,0.4,0.6,0.8, and 1.0 g/plant) as ammonium nitrate in split applications. Data for plant fresh mass and N uptake were recorded. The logistic model described the data for both cultivars quite well, with correlation coefficients of 0.98 and above. The logistic model was also applied to field data for average head mass of `South Bay' lettuce following application of N at 0,56,112,168,224, and 280 kg·ha-1. Logistic, linear-plateau, and quadratic models were compared for the field data. Coefficients for the linear-plateau model were derived from the logistic model. All three models for lettuce production were compared graphically and analytically. The model coefficients were then used to make improved estimates of fertilizer recommendations for field production of lettuce.

Evaluated at any admissible word, these maps induce linear relations between multiple zeta values. In this note, we show that the derivation relations for multiple zeta values are contained in this class of linear relations.

It was evaluated the feasibility of growing lettuce intercropped with Nile tilapia farming in a hydroponic system and the efficiency upon the improvement of the quality of the effluent. The experimental structure was composed of one module for fish production and other for plant production in the hydroponic system. It was used production technique NFT (Nutrient Film Technique), and the nutrient solution used was the effluent of fish farming. It was used a randomized block experimental design with four treatments and three replications, considering each repetition an 8-day cycle in hydroponics. The treatments were: 20; 40, 60 and 80 plants for the first, second, third and fourth treatments, respectively. Electrical conductivity, pH, temperature and dissolved oxygen did not change (P>0.05) in relation to the input effluent and they were not affected (P>0.05) by the number of plants. We observed a linear effect of number of plants on the parameters orthophosphate and nitrite, ie the higher the number the greater the removal of plants for these parameters in the water. The percentage of nitrogen in leaves and roots of lettuce was not influenced by the number of plants. There was a linear effect of the number of plants on the accumulation in lettuce leaves parameters dry matter, nitrogen and phosphorus. There was a linear effect of the number of plants on the accumulation of dry matter and phosphorus and quadratic effect on nitrogen accumulation in roots of lettuce.There is a technical feasibility of integrating the intensive Nile tilapia farming in a closed system of recirculating water in the production of hydroponic lettuce, with nutrients remotion such as nitrogen and phosphorus from the effluents and their incorporation in leaves and roots of lettuce.

The first goal of this study was to determine the packaging film O2 permeability required to maintain a steady-state O2 concentration of 3% in modified-atmosphere packaging (MAP) of minimally processed romaine lettuce (Lactuca sativa L.). The second goal of the study was to determine the extent to which MAP could preserve lettuce quality and consequently extend product shelf life. Oxygen consumption rates of commercially prepared lettuce samples were determined in a closed system for each of three atmospheres (3% O2 combined with either 6%, 10%, or 14% CO2). Enzymatic, quadratic, and linear mathematical models were compared to determine which best described the respiratory data. The linear model was the most suitable and was used to predict the O2 consumption rate of the minimally processed romaine lettuce under the desired package headspace gas concentrations. The predicted O2 consumption rate was used to calculate the necessary O2 permeability for the packaging film. Packages (21.6 × 25.4 cm) were constructed from a polypropylene-polyethylene-laminate film with the appropriate O2 permeability. Packaged samples were stored under three modified atmospheres (MAs) (3% O2 combined with either 6%, 10%, or 14% CO2) for 20 days, and headspace gas concentrations, lettuce appearance, and color were evaluated every other day. Growth of pectinolytic and lactic acid bacteria was also studied. The O2 consumption rate of the lettuce decreased with increasing CO2 levels. The O2 levels in the MA packages equilibrated at 7% to 11%. Compared to a control atmosphere of air, MAP delayed the development of tissue discoloration. Preliminary results indicated no effect of MAP on microbial growth. Of the three CO2 levels, 10% was slightly more effective than 6% and 14%. Critical choice of packaging permeabilities combined with MAP maintained the quality of minimally processed romaine lettuce and thereby increased shelf life by about 50%.

Information geometry is the study of the intrinsic geometric properties of manifolds consisting of a probability distribution and provides a deeper understanding of statistical inference. Based on this discipline, this letter reports on the influence of the signal processing on the geometric structure of the statistical manifold in terms of estimation issues. This letter defines the intrinsic parameter submanifold, which reflects the essential geometric characteristics of the estimation issues. Moreover, the intrinsic parameter submanifold is proven to be a tighter one after signal processing. In addition, the necessary and sufficient condition of invariant signal processing of the geometric structure, i.e., isometric signal processing, is given. Specifically, considering the processing with the linear form, the construction method of linear isometric signal processing is proposed, and its properties are presented in this letter.

This study assessed the die-off of Escherichia coli (E. coli) and Ascaris suum on lettuce (Great Lakes 118) and cabbage (Brassica oleracea var capitata) in wastewater-irrigated fields using comparative mathematical die-off models. The study revealed that none of the survival curves of E. coli and A. suum was best fitted with the log-linear model, indicating that the classical first-order kinetic approach is inadequate in many cases. The biphasic die-off model best described the die-off of E. coli on lettuce (kmax1 = 2.62 day−1 and kmax2 = 0.22 day−1) and cabbage (kmax1 = 1.06 day−1 and kmax2 = 0.53 day−1). The die-off of A. suum on lettuce was best described by the biphasic model (kmax1 = 0.48 day−1 and kmax2 = 0.01 day−1) and best described by log linear + tail (kmax = 0.44) on cabbage. A comparative health risk assessment associated with the consumption of lettuce showed significant underestimation of the number of days of irrigation cessation required to achieve E. coli O157:H7 and Ascaris tolerable annual infection risk when using biphasic die-off rates compared with other die-off rates. The study stresses the need to test different die-off models as inputs for quantitative microbial risk assessment (QMRA) particularly for interventions associated with health risk reduction.

We give a classical algorithm for linear regression analogous to the quantum matrix inversion algorithm [Harrow, Hassidim, and Lloyd, Physical Review Letters'09] for low-rank matrices [Wossnig, Zhao, and Prakash, Physical Review Letters'18], when the input matrix A is stored in a data structure applicable for QRAM-based state preparation.Namely, suppose we are given an A∈Cm×n with minimum non-zero singular value σ which supports certain efficient ℓ2-norm importance sampling queries, along with a b∈Cm. Then, for some x∈Cn satisfying ‖x–A+b‖≤ε‖A+b‖, we can output a measurement of |x⟩ in the computational basis and output an entry of x with classical algorithms that run in O~(‖A‖F6‖A‖6σ12ε4) and O~(‖A‖F6‖A‖2σ8ε4) time, respectively. This improves on previous "quantum-inspired" algorithms in this line of research by at least a factor of ‖A‖16σ16ε2 [Chia, Gilyén, Li, Lin, Tang, and Wang, STOC'20]. As a consequence, we show that quantum computers can achieve at most a factor-of-12 speedup for linear regression in this QRAM data structure setting and related settings. Our work applies techniques from sketching algorithms and optimization to the quantum-inspired literature. Unlike earlier works, this is a promising avenue that could lead to feasible implementations of classical regression in a quantum-inspired settings, for comparison against future quantum computers.

This study investigated the volume of wastewater retained on the surface of three different varieties of lettuce, Iceberg, Cos, and Oak leaf, following submersion in wastewater of different microbial qualities (10, 102, 103, and 104E. coli MPN/100 mL) as a surrogate method for estimation of contamination of spray-irrigated lettuce. Uniquely, Escherichiacoli was enumerated, after submersion, on both the outer and inner leaves and in a composite sample of lettuce. E. coli were enumerated using two techniques. Firstly, from samples of leaves – the direct method. Secondly, using an indirect method, where the E. coli concentrations were estimated from the volume of wastewater retained by the lettuce and the E. coli concentration of the wastewater. The results showed that different varieties of lettuce retained significantly different volumes of wastewater (p < 0.01). No statistical differences (p > 0.01) were detected between E. coli counts obtained from different parts of lettuce, nor between the direct and indirect enumeration methods. Statistically significant linear relationships were derived relating the E. coli concentration of the wastewater in which the lettuces were submerged to the subsequent E. coli count on each variety the lettuce.

The effectiveness of water lettuce in removing pollutants including organic pollutants, nitrogen (NH3-N) and total phosphorus (TP) from livestock wastewater along with the physiological effects and their correlations, was studied for the first time. The results showed that the water lettuce had higher removal efficiency with low concentrations of livestock wastewater. The removal efficiency of water lettuce for different initial concentrations of livestock wastewater within 8 d was as follows: chemical oxygen demand (CODcr) (68–82%) > NH3-N (57–69%) >TP (27–45%). The speed of purification of water lettuce for CODcr, NH3-N and TP conformed to first order kinetics equations. The water quality indices CODcr, NH3-N and TP had a higher linear correlation with peroxidase (POD) activity (R2 > 0.92) than with superoxide dismutase (SOD) and catalase (CAT) activity, which indicates that the main reacting enzyme of water lettuce under high CODcr stress is peroxidase.

This quote is part of the letter that Barry B. wrote about the fourth-grade mathematics program at Saint Thomas, Regional School. I doubt that he or anyone else would have written such a letter to me five years ago. My mathematics program, like so many around the country, was textbook driven, linear, abstract.

In this letter, the problem of feedback controller design to achieve synchronization for neural network of neutral type with stochastic perturbation is considered. Based on Lyapunov method and LMI (linear matrix inequality) framework, the goal of this letter is to derive an existence criterion of the controller for the synchronization between master and response networks.

Verticillium longisporum is an economically important vascular pathogen of Brassicaceae crops in different parts of the world. V. longisporum is a diploid hybrid that consists of three different lineages, each of which originated from a separate hybridization event between two different sets of parental species. We used 20 isolates representing the three V. longisporum lineages and the relative V. dahliae, and performed pathogenicity tests on 11 different hosts, including artichoke, cabbage, cauliflower, cotton, eggplant, horseradish, lettuce, linseed, oilseed rape (canola), tomato, and watermelon. V. longisporum was overall more virulent on the Brassicaceae crops than V. dahliae, which was more virulent than V. longisporum across the non-Brassicaceae crops. There were differences in virulence between the three V. longisporum lineages. V. longisporum lineage A1/D1 was the most virulent lineage on oilseed rape, and V. longisporum lineage A1/D2 was the most virulent lineage on cabbage and horseradish. We also found that on the non-Brassicaceae hosts eggplant, tomato, lettuce, and watermelon, V. longisporum was more or equally virulent than V. dahliae. This suggests that V. longisporum may have a wider potential host range than currently appreciated.
