Resumen

This paper presents an efficient fast Walsh–Hadamard–Hartley transform (FWHT) algorithm that incorporates the computation of the Walsh-Hadamard transform (WHT) with the discrete Hartley transform (DHT) into an orthogonal, unitary single fast transform possesses the block diagonal structure. The proposed algorithm is implemented in an integrated butterfly structure utilizing the sparse matrices factorization approach and the Kronecker (tensor) product technique, which proved a valuable and fast tool for developing and analyzing the proposed algorithm. The proposed approach was distinguished by ease of implementation and reduced computational complexity compared to previous algorithms, which were based on the concatenation of WHT and FHT by saving up to 3N-4 of real multiplication and 7.5N-10 of real addition.

Resumen

Image data augmentation (IDA) is common when deep learning is used for image classification to address the issue of overfitting. Overfitting occurs when the datasets are small and the deep learning models have a huge capacity. Overfitting models have low training errors but high validation errors and result in poor generalization. Several methods have been researched in this context, but frequency domain-based methods are less explored. In this research, we have explored the Hadamard and Walsh space and developed two hybrid technique for IDA. The proposed techniques use a combination of Hadamard/Walsh transform and geometrical transformations. Empirical study is carried out using the VGG-16 model for image classification on the CIFAR 10 dataset and the results are compared with existing methods. The analysis of the results shows that the proposed techniques improve the evaluation parameters significantly. Further, analysis of training loss vs. validation loss shows that the proposed Hadamard-based hybrid methods have better generalization ability than the proposed Walsh-based hybrid method.

Resumen

Audio hiding is method for embedding information into an audio signal. It seeks to do so in a robust Fashion, while not perceivably degrading the host signal (coves audio). Hiding data in audio signals presents & varicty of challenges: due in part to the wider dynamic and differential range of the Human Auditory System (HAS) as compared to other senses. Transform are usually used for robust audio hiding (audio watcrmarking). But, the audio hiding process is affected by the type of transform used.

Resumen

Options have been developed for constructing circulant matrices of any M-sequence (MS) based on automorphic multiplicative groups of the extended Galois field, constructed using an irreducible primitive polynomial, on the basis of which the original MS is formed. The result of this approach is the identification of new methods for transforming MS circulant matrices to a matrix of Walsh functions, ordered by the powers of the antiderivative element of the field. It is shown for the first time that, depending on the initial conditions of the transformation, a set of any number of any cyclic shifts of the MP, shifted relative to each other by one symbol, can be transformed to any rows of the ordered matrix of Walsh functions, following one another. This circumstance makes it possible to simplify the MS synchronization algorithm for a known range of its cyclic shifts, especially in the case of large periods of its repetition, and also to reduce the computational complexity of the processing algorithm when working in a truncated basis of Walsh–Hadamard functions.

Resumen

An automated dead-end (single pass, no recirculation) ultrafiltration device, the Portable Multi-use Automated Concentration System (PMACS), was evaluated as a means to concentrate Escherichia coli O157:H7 from 40 liters of simulated commercial lettuce wash water. The assessment included generating, sieving, and concentrating sanitizer-free lettuce wash water, either uninoculated or inoculated with green fluorescent protein–transformed E. coli O157:H7 at a high (1.00 log CFU/ml) or low (−1.00 log CFU/ml) concentration. Cells collected within the filters were recovered in approximately 400 ml of buffer to create lettuce wash retentates. The extent of concentration was determined by viable plate counts using a medium selective for the transformed E. coli O157:H7. The samples were qualitatively analyzed for E. coli O157:H7 according to the U.S. Food and Drug Administration Bacteriological Analytical Manual enrichment method and with an electrochemiluminescence immunoassay. This concentration method was then evaluated in a pilot-scale production line at Michigan State University using chlorinated (100, 30, and 10 ppm of available chlorine) lettuce wash water. The total PMACS processing times were 82 ±6 and 65 ±5 min for sanitizer-free and chlorinated washes, respectively. Overall, E. coli O157:H7 populations were approximately 2 log higher in retentates than in unconcentrated lettuce wash samples. The higher E. coli O157:H7 levels in the retentates enabled cultural and electrochemiluminescence immunoassay detection in some samples when the corresponding lettuce wash samples were negative. When combined with standard and rapid detection methods, the PMACS concentration method may provide a means to enhance pathogen monitoring of produce wash water.

Texto completo

Resumen

Wavefront sensing is an essential technique in optical imaging, adaptive optics, and atmospheric turbulence correction. Traditional wavefront reconstruction methods, including the Gerchberg–Saxton (GS) algorithm and phase diversity (PD) techniques, are often limited by issues such as low inversion accuracy, slow convergence, and the presence of multiple possible solutions. Recent developments in deep learning have led to new methods, although conventional CNN-based models still face challenges in effectively capturing global context. To overcome these limitations, we propose a Transformer-based single-shot wavefront sensing method, which directly reconstructs wavefront aberrations from focal plane intensity images. Our model integrates a Normalization-based Attention Module (NAM) into the CoAtNet architecture, which strengthens feature extraction and leads to more accurate wavefront characterization. Experimental results in both simulated and real-world conditions indicate that our method achieves a 4.5% reduction in normalized wavefront error (NWE) compared to ResNet34, suggesting improved performance over conventional deep learning models. Additionally, by leveraging Walsh function modulation, our approach resolves the multiple-solution problem inherent in phase retrieval techniques. The proposed model achieves high accuracy, fast convergence, and simplicity in implementation, making it a promising solution for wavefront sensing applications.

Resumen

Abstract This test was conducted in a 7-yr-old orchard with under-tree irrigation. The experimental design was a randomized complete block with 4 single-tree replicates/treatment. Materials were applied to the point of drip with a handgun sprayer operated at 400-500 psi. Rates were based on a dilute application of 400 gal/acre. The first spray was timed to coincide with petal fall, about 10 d after the first nymphs had hatched. The remaining treatments were applied at 1-wk intervals. WALH densities were determined by counting nymphs on 20 leaves/tree showing visible injury on the upper surface. Counts were made before treatment and at 3, 7, and 14 DAT. All treatments were evaluated on 5 Jun when half of the nymphs had transformed into adults. Cumulative leafhopper-days (CLDs) were calculated by averaging 2 successive nymph counts, multiplying by the number of intervening days, and adding these over the season.

Texto completo

Resumen

In this work, new approaches are proposed for the 3D decomposition of a cubical tensor of size N × N × N for N = 2n through hierarchical deterministic orthogonal transforms with low computational complexity, whose kernels are based on the Walsh-Hadamard Transform (WHT) and the Complex Hadamard Transform (CHT). On the basis of the symmetrical properties of the real and complex Walsh-Hadamard matrices are developed fast computational algorithms whose computational complexity is compared with that of the famous deterministic transforms: the 3D Fast Fourier Transform, the 3D Discrete Wavelet Transform and the statistical Hierarchical Tucker decomposition. The comparison results show the lower computational complexity of the offered algorithms. Additionally, they ensure the high energy concentration of the original tensor into a small number of coefficients of the so calculated transformed spectrum tensor. The main advantage of the proposed algorithms is the reduction of the needed calculations due to the low number of hierarchical levels compared to the significant number of iterations needed to achieve the required decomposition accuracy based on the statistical methods. The choice of the 3D hierarchical decomposition is defined by the requirements and limitations related to the corresponding application area.

Resumen

Based on the analysis of the structures of isomorphic multiplicative groups of extended Galois fields, it is established that any cyclic shift of a pseudo-random Gold sequence can be transformed into a function belonging to the complete set of analogues of Rademacher functions of the corresponding dimension. This made it possible to develop a new algorithm for fast synchronization of Gold sequences based on the calculation of their discrete convolution using fast spectral transformation in a truncated basis of Walsh–Hadamard functions. The gain of the developed algorithm in terms of the number of arithmetic operations compared to the traditional method of calculating discrete convolution increases with increasing sequence length N and for N=511.1023 is approximately 3.4 times.

Resumen

There is a lot of power loss in the power transmission, and the loss comes from power transformers contribute very much to this. So the implement of energy efficiency grade for power transformers has great significance to the development of power transformer, which can wash out the high energy-consuming transformer, decrease the power loss, and increase the efficiency of power transmission. The energy consumption of transformer consists of no load loss and load loss. In this test, I analyze the experiments for no load loss and load loss with the “Minimum allowable values of energy efficiency and energy efficiency grades for power transformers”, ascertaining the transformer’s efficiency grade.

Resumen

A revista Arturo colocou em cena, em 1944, o concretismo não representativo nas vanguardas do Prata se enfrentando ao primeiro governo peronista, força representativa por excelência. Daí em diante o debate da representação política com a não representação artística teve algumas emergências significativas. No presente texto se indaga duas possíveis emergências dessa constelação: a revista El Cielo (analisando brevemente o posterior percurso dos seus editores, César Aira e Arturo Carrera) e o trabalho editorial e por vezes clandestino de Rodolfo Walsh no Semanário de la CGT de los argentinos, em Cadena Informativa e no jornal Noticias, de Montoneros. As insurgências populares de 1969, o Cordobazo sobre tudo, transformam de tal modo esses dois percursos que o debate inaugurado em 1944 por Arturo adquire outras derivas.

Resumen

It is shown that the convenient processing facilities of digital signals that varying in a finite range of amplitudes are non-binary Galois fields, the numbers of which elements are equal to prime numbers. Within choosing a sampling interval which corresponding to such a Galois field, it becomes possible to construct a Galois field Fourier transform, a distinctive feature of which is the exact correspondence with the ranges of variation of the amplitudes of the original signal and its digital spectrum. This favorably distinguishes the Galois Field Fourier Transform of the proposed type from the spectra, which calculated using, for example, the Walsh basis. It is also shown, that Galois Field Fourier Transforms of the proposed type have the same properties as the Fourier transform associated with the expansion in terms of the basis of harmonic functions. In particular, an analogue of the classical correlation, which connected the signal spectrum and its derivative, was obtained. On this basis proved, that the using of the proposed type of Galois fields makes it possible to develop a complete analogue of the transfer function apparatus, but only for signals presented in digital form.

Resumen

The gravity anomaly expression produced by most geologic structures can be represented by a continuous function of both shape (shape‐factor) and depth‐related variables with an amplitude coefficient related to mass (Abdelrahman and El‐Araby, 1993). Few methods have been developed to determine the shape of the buried geologic structure from residual gravity anomaly profiles. These methods include a Walsh transform approach (Shaw and Agarwal, 1990) and the employment of a correlation factor between successive least‐squares residuals (Abdelrahman and El‐Araby 1993). In the present note, a least‐squares minimization approach to shape‐factor determination from a residual gravity anomaly profile is presented. The problem of the shape‐factor determination is transformed into the problem of finding a solution of a nonlinear equation of the form f(q) = 0.

Resumen

An integrated system has been developed to remediate soils contaminated with pentachlorophenol (PCP) and polycyclic aromatic hydrocarbons (PAHs). This system involves the coupling of two treatment technologies, soil solvent washing and anaerobic biotreatment of the extract. Specifically, this study evaluated the effectiveness of the granular activated carbon (GAC) fluidized-bed reactor to treat a synthetic waste stream of PCP and four PAHs (naphthalene, acenaphthene, pyrene, and benzo(b)fluoranthene) under anaerobic conditions. This waste stream was intended to simulate the wash fluids from a soil washing process treating soils from a wood preserving site. The reactor achieved a removal efficiency of greater than 99.8% for PCP with conversion to its dechlorination intermediates ranging from 47% to 77%. Effluent, carbon extraction, and isotherm data also indicate that naphthalene and acenaphthene were removed from the liquid phase with efficiencies of 86% and 93%, respectively. Effluent levels of pyrene and benzo(b)fluoranthene were extremely low due to the adsorptive capacity of GAC for these compounds. Experimental evidence does not suggest that these compounds were chemically transformed within the reactor.

Resumen

Abstract Objective: The objective of this work is to detect video shot boundary which is an important phase in the domain of video processing. The applications such as indexing, retrieval and browsing of video are majorly depends on accurate detection of shot boundary so the detection is highly necessary in the area of video processing. Methods: Many researchers have contributed to the field of Shot Boundary Detection (SBD) to improve video processing throughout the previous decade. Some of the techniques have detected abrupt as well as gradual transitions with remarkable performance metrics values, but they compromised with the execution time and operating speed. Some of the techniques proposed and implemented the simpler approaches, but failed to detect the gradual transitions. Additionally, the effects like illuminations and camera motion lead to produce false results. Thus, taking these aspects into consideration, the novel approach for SBD has to be implemented. Findings: In this paper, fusion of transform and filtering at an early stage has been applied for reducing the false hits that occurs due to illumination noise. The fusion of transform with appropriate classifier enhances the detection performance. Another deep learning based technique with Rider bald eagle search optimization given the solution for the SBD. Novelty and applications: The proposed two approaches give the detection of abrupt and gradual transitions. It has been noticed that the said approaches found effective against the illuminations. To evaluate the performance it uses precision, recall and F1 score as performance metrics. The experiments are performed on latest TRECVID datasets and few open source video datasets. Keywords: Shot Boundary Detection; Walsh Hadamard Transform (WHT); Dual Tree Complex Wavelet Transform; Deep Belief Network; Deep Convolutional Neural Network

Resumen

Abstract. Archeological and geoscientific research in loess landscapes remains challenging due to erosional discordances and the relocation of sediments by fluvial erosion and slope wash. The Lower Rhine Embayment (LRE) can serve as a blueprint for archeological and paleoenvironmental research in loess landscapes of Central Europe. The accumulation of wind-blown dust; paleosols developed therein; and the archeological artifacts preserved in loess, colluvial or alluvial sediments are evidence of the Pleistocene and Holocene dynamics of the landscape. Geomorphologic processes in different and specific relief positions must be considered different processes that transform and relocate sediments and archeological remains. Besides aeolian accumulation, erosion and deflation have also transformed the landscape of the LRE. These include fluvial slope wash, gully formation, colluviation, and periglacial processes such as solifluction, cryoturbation and the formation of ice wedge pseudomorphs. In addition, other post-depositional processes, including weathering and soil formation, modify the sedimentary record. In light of the landscape evolution from more hilly landscapes to the flat, agriculturally used terrain we see today, we highlight the relevance and importance of different geomorphological and soil processes including their impacts and challenges for archeological and geoscientific studies.

Sustained falls of cold water were prescribed to cool hot, inflamed brains, and to instil fear to tame impetuous wills. By the middle of the century showers had appeared in both asylums and prisons, but shower-related deaths led to their decline. Rather than being abandoned, however, the shower was transformed by the use of warm water to economically wash the skins of prison and asylum populations. In stark contrast to an involuntary, deliberately unpleasant treatment, by the end of the century the shower was a desirable product for the improvement of personal hygiene and population health.

Resumen

The filter banks multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) is developing multicarrier modulation technique used in the next wireless communication system (5G). FBMC/OQAM supports high data rate and high band width efficiency. However, one of the major drawbacks of FBMC system is high peak to Average Power Ratio (PAPR) of the transmitted signal, which causes serious degradation in performance of the system. Therefore, it is required to use a proper PAPR scheme at the transmitter to reduce the PAPR. In this paper, a hybrid scheme is investigated with the combination of preceding transform technique and Mu Law Companding technique to reduce PAPR in FBMC systems. Moreover, four preceding techniques are examined to find the best Precoding technique which can be used with Mu law commanding. We assessed the discrete Hartley transform (DHT). The discrete cosine transformed (DCT), the Discrete Sine Transform (DST), and the Walsh Hadamard transforms (WHT) which are applied separately with Mu Companding. The numerical results verify that the FBMC systems with all Precoding technique combined with Mu law commanding can improve PAPR performance of the signals greatly with the best results achieved when the combination scheme consists of the DST Precoding and Mu law commanding for both PAPR and BER performance.

Resumen

Assim como uma constelação é formada por estrelas individuais que juntas criam uma representação significativa, a expressão constelações decoloniais sugere a interconexão de diversas imagens, práticas e movimentos decoloniais que, juntos, formam um quadro mais amplo e compreensivo de resistência. Sugere ainda a inclusão de múltiplas perspectivas, vozes e experiências de diferentes culturas. De modo semelhante às constelações, que são compostas por múltiplos pontos de luz, cada imagem, pensamento, perspectiva, contribui para mapear e navegar por territórios culturais e históricos periféricos ou suprimidos pelo colonialismo, recuperando e valorizando esses espaços através de uma abordagem decolonial. Neste estudo, adotamos uma perspectiva decolonial da interculturalidade (Martins, 2020; Mignolo & Walsh, 2018), entendida como um diálogo genuíno entre povos e instituições, procurando promover a igualdade de oportunidades. A abordagem da nossa investigação é qualitativa, fundamentada em pesquisa bibliográfica, explorando conceitos como interculturalidade, decolonialidade e pós-musealidade. Analisamos alguns museus que estão a transformar as suas exposições e narrativas, em prol de uma perspectiva decolonial. Exploramos algumas dinâmicas no African Museum, na Bélgica; no Pitt Rivers Museum, na Grã-Bretanha; e no Museu Virtual da Lusofonia, no Google Arts & Culture, com sede física em Portugal. Estes museus são apresentados como estudos de caso que exemplificam a aproximação ao paradigma do pós-museu.

Resumen

Abstract The test was carried out in a 17-yr-old block of'Red Delicious' and 'Stayman' apples. Treatments were applied with an FMC PT50 airblast sprayer operated at 300 psi and 1.5 mph to deliver 225 gal/acre. Treatment dates were 22 Apr, pink (P); 12 May, petal fall (PF); 29 May, first cover (IC); 18 Jun, second cover (2C); 8 Jul, third cover (3C); and 14 Aug, fourth cover (4C). The single-tree plots, replicated 4 times (3 'Stayman,' 1 'Red Delicious'), were arranged in a randomized complete block design. For disease control the entire orchard was sprayed with Polyram as needed. Data were transformed to × + 1 or arcsine × prior to analysis of variance and separation of means by Duncan's new multiple range test. In the tables, means followed by the same letter are not significantly different at a = 0.05, DMRT. Sampling methods were as follows: ERM, motile stages per leaf as determined from a pooled sample of 15 leaves per tree; S. punctum, average S. punctum/3-min count/tree; AA, average AA/10 most infested terminals/tree; RAA, average RAA colonies per tree; WALH, average WALH-damaged leaves/100 leaves/tree; and STLM, average STLM mines/3-min count/ tree. All other pest damage is expressed as the number of damaged fruit/100 fruit/tree.

Resumen

Businesses have been dynamically and quickly changing for centuries, largely due to technological improvements. Around the world, intelligent, digital, and integrated representations of technology are proliferating (Panetta, 2018). The Internet of Things (IoT), Virtual human-machine interfaces, and artificial intelligence are examples of cutting-edge business technologies that have substantial growth potential (Brynjolfsson, Hui, and Liu, 2019; Briggs and Buchholz, 2019). However, if a firm is not digitally structured and transformed for this purpose, it will be difficult for technology-driven growth to have the most impact on enterprises. To increase productivity and efficiency, digital transformation requires integrating information, infrastructure, processes, and people with digital aspects and procedures. An excellent example of digital transformation may be seen in the situations of LEGO and Starbucks. After reorganizing and going digital, LEGO climbed the value chain due to this new revenue stream from movies, mobile games, and mobile applications. Starbucks put a premium on customers’ loyalty to create a digitalized customer experience. By offering a simple and convenient purchasing experience, the mobile order and pay app became their main digital transformation objective (Anthony et al, 2020). In essence, digital transformation enabled new economic value exchange and competitive advantage for organizations like Starbucks and LEGO (Walsh, 2017). These and many other digital transformation stories transpire macro or national-level spillovers, with the government of the day being the driving force.

Resumen

The paper presents a study on the use of alkaline fusion to produce nanostructured sodium titanate from rutile mineral. The spherical structure of the micron-sized starting material changed and transformed to a two-dimensional nanostructure after the alkaline fusion process. After 7 hours dissolution with 30% NaOH, the growth of sodium titanate nanorod is observed, and after undergoing prolonged dissolution, nanowires, with an average diameter of 20-40 nm and a length of 1-4 µm are formed. The study also showed that using 0.1M HCl to wash the titanate complex results in a sodium titanate that is free from NaOH residue, although at higher molarities, the nanostructure will collapse, and spherical grains formed. The important role of alkaline fusion in this hydrothermal process is that it will reduce dissolution time, while NaOH concentration is required for the growth of nanostructured sodium titanate.

Resumen

1. The effect of the calcium channel antagonist diltiazem on pH-induced sustained nociceptor excitation was investigated in a rat skin-saphenous nerve preparation, in vitro, where receptive fields of identified and isolated single fibers were superfused at the corium side with controlled solutions to assess their chemosensitivity. 2. Unmyelinated mechano-heat sensitive ("polymodal") C fiber terminals (n = 78) were superfused with a CO2-saturated synthetic interstitial fluid (CO2-SIF, pH 6.1). Fibers responding to this acid pH condition (n = 60; 77%) were further stimulated for > or = 30 min and additionally treated with diltiazem in various concentrations (10(-6)-10(-3) M) during the middle 10-min period. Usually only one concentration of diltiazem was applied per fiber, although in some cases diltiazem was applied repeatedly and in increasing concentrations. 3. Diltiazem dose-dependently and reversibly reduced the pH-induced sustained nociceptor discharge to a significant degree or completely abolished it. With higher concentrations, both the relative number of units affected and the average amount of suppression were enhanced. The half-maximal blocking concentration (IC50) was estimated to 1.1.10(-4) M diltiazem, the half-maximal concentration for gradual suppression of the pH response was 2.10(-5) M diltiazem. 4. Also, the delay of onset of the suppressive effect decreased with higher diltiazem concentrations. After diltiazem, a partial recovery of the pH-induced discharge was achieved within 10 min depending on the degree of suppression. 5. Before, after, and sometimes during the superfusion, the mechanical (von Frey) thresholds were determined and found to be significantly increased after partial wash out of diltiazem (10(-4) and 10(-3) M; P < 0.006 and P < 0.008, respectively). After 10(-3) M diltiazem superfusion (and 10 min of wash-out), the responsiveness to mechanical stimulation of the majority of the fibers was still totally lost. 6. Heat thresholds were still found to be significantly increased after treatment with diltiazem at 10(-3) and 10(-4) M concentrations (and 10 min of wash out), but appeared unchanged after wash out of lower concentrations. 7. In five mechano-heat-sensitive C fibers, electrical stimulation via a microelectrode placed in the receptive field was used to demonstrate a diltiazem-dose-dependent (10(-5), 10(-4), 10(-3) M) progressive retardation of the nerve conduction velocity and an increase of the electrical threshold. Superfusion for 6 min of diltiazem 10(-5) M was sufficient to block axonal conduction as well as mechanosensitivity, which both recovered synchronously during wash out. 8. It can be concluded from the results that the suppressive effect of diltiazem on pH-induced nociceptor excitation can be explained by a use-dependent axonal block, comparable with the action of local anesthetics and affecting all modalities of sensory responsiveness. 9. The findings provide no indication that a transformed calcium channel specifically sensitive to diltiazem is involved in pH-induced sustained nociceptor excitation.

Resumen

Apresentamos uma pesquisa, que se objetiva analisar a articulação da Matriz Curricular das Licenciaturas em Educação do Campo com habilitação em Ciências da Natureza (LEdoCs) do Estado de Goiás na promoção positiva da Formação Docente Decolonial, baseada na proposta de Walsh (2009), nas concepções de Freire (1979, 2005), Mignolo (2008), Quijano (1992, 2005) dentre outros autores. Metodologicamente de abordagem qualitativa (Bogdan; Biklen 1994), sistematiza um levantamento bibliográfico, cujos dados foram construídos mediante a análise documental, através dos Projetos Político Pedagógicos e de entrevistas semiestruturadas dos docentes e coordenadoras de duas LEdoCs no Estado de Goiás (UFG Regional Goiás e UFCAT). Estamos cientes que o currículo engloba diferentes perspectivas formativas que imbricam relações de poder e de saber. Para tanto, discutimos brevemente a relação entre colonialidade e decolonialidade, Educação do Campo, Matriz Curricular e formação docente. Os resultados obtidos mostraram que as duas LEdoCs analisadas utilizam a Matriz Curricular para promover o fortalecimento de uma formação inicial decolonial de professores/as do campo e que o trabalho pedagógico nessa perspectiva visa uma abertura ao diálogo não apenas entre conteúdos de formação por áreas do conhecimento (interdisciplinaridade), mas uma ação pedagógica que possibilite uma práxis voltada para a integração de saberes, para além das disciplinas e da hierarquização do saber. Uma prática pedagógica que estimula a construir, suscitar outros questionamentos críticos e transformar os licenciandos em indivíduos livres, justos, autônomos, conscientes e críticos, capazes de produzir o seu próprio conhecimento.

Resumen

Abstract A 15-year-old orchard located at the Rutgers Fruit Research & Development Center, Cream Ridge, NJ was used in this test. Sprays were applied to 3 single-tree replicates of ‘Red Delicious’ arranged in a randomized complete block design. Trees were sprayed to runoff (ca 5 gal/tree; 300 GPA) using a hydraulic sprayer equipped with a hand-gun and operated at 200 psi. Spray dates were 11 Apr (P) and 30 Apr (PF). For disease control the entire orchard was sprayed with Captan and Polyram as needed. European red mite estimates were made by randomly picking 25 leaves per replicate, brushing the mites onto glass plates and counting mobile mites. Sampling methods for insects listed in the table are as follows: EASF = no. of EASF damaged fruit/3 minute count; AA = avg no. of AA/terminal/tree (20 terminals counted); RAA = no. of RAA colonies/tree; STLM = no. of STLM mines/3 minute count; WALHa = no. of WALH nymphs and adults/3 minute count; WALHb = no. of WALH damaged leaves/3 minute count; Stethorus = no. of S. punctum larvae, pupae and adults/3 minute count; Russet = % russet/fruit (100 fruit evaluated). Mite-days were calculated as follows: MD = MD1 + [(Ml + M2)/2 × Y], where MD1 = mite days already accumulated, Ml = avg ERM/leaf on a given counting date, M2 = avg ERM/leaf on the next counting date after Ml and Y = number of days between Ml and M2. Data were transformed to × + 1, or arcsin (x) prior to analysis of variance and comparison of means. In tables, numbers followed by the same letter are not significantly different (alpha = 0.05, DMRT).

Resumen

Modern cryptographic applications use cryptographic algorithms with a symmetric key. They provide high conversion rates and resistance to crypto-graphic attacks. To complicate the plaintext – cipher-text ratio, symmetric ciphers usually use nonlinear substitutions (S-boxes). S-boxes cryptographic metrics play a crucial role in ensuring resilience to most known attacks (differential, linear, algebraic, and other cryptanalysis methods). However, generating efficient s-boxes is a challenge. Even for small input/output sizes, there are an extremely large number of possible solutions. Usually, the substitution is represented as a set of Boolean functions. This allows you to apply discrete transformations, for example, Walsh-Hadamard, to evaluate cryptographic indicators. However, methods for generating s-boxes by selecting suitable Boolean functions are extremely complex. Therefore, it is necessary to study new mathematical methods for representing nonlinear substitutions, studying their cryptographic properties, and developing generation algorithms. In this paper, we propose applying factorial number systems to represent nonlinear substitutions. Each substitution can be represented in a unique way through a set of inversions, which, in turn, can be transformed into a factorial number. That is, we can naturally arrange all substitutions by numbering them in the factorial number system. We give examples of such numbering and investigate the cryptographic characteristics of S-boxes with their initial numbers. In particular, we show how the variable functions used in heuristic algorithms for generating non-linear substitutions change. The results obtained can be used to simplify heuristic methods in order to speed up the generation of non-linear substitutions.

Resumen

Mangoes (Mangifera indica L.) are an important kind of perennial fruit tree, but their biochemical testing method and transformation technology were insufficient and had not been rigorously explored. The protoplast technology is an excellent method for creating a rapid and effective tool for transient expression and transformation assays, particularly in plants that lack an Agrobacterium-mediated plant transformation system. This study optimized the conditions of the protoplast isolation and transformation system, which can provide a lot of help in the gene expression regulation study of mango. The most beneficial protoplast isolation conditions were 150 mg/mL of cellulase R-10 and 180 mg/mL of macerozyme R-10 in the digestion solution at pH 5.6 and 12 h of digestion time. The 0.16 M and 0.08 M mannitol in wash solution (WI) and suspension for counting (MMG), respectively, were optimal for the protoplast isolation yield. The isolated leaf protoplasts (~5.4 × 105 cells/10 mL) were transfected for 30 min mediated by 40% calcium-chloride-based polyethylene glycol (PEG)-4000-CaCl2, from which 84.38% of the protoplasts were transformed. About 0.08 M and 0.12 M of mannitol concentration in MMG and transfection solutions, respectively, were optimal for protoplast viability. Under the florescence signal, GFP was seen in the transformed protoplasts. This showed that the target gene was successfully induced into the protoplast and that it can be transcribed and translated. Experimental results in this paper show that our high-efficiency protoplast isolation and PEG-mediated transformation protocols can provide excellent new methods for creating a rapid and effective tool for the molecular mechanism study of mangoes.

Resumen

This study investigates bubble size measurements, bubble characteristics, and the relationship between key operating variables and gas dispersion properties in column flotation. As the frother concentration increased to 120 ppm, the bubble size distribution (BSD) transformed from bimodal to unimodal and achieved a minimum bubble size of 0.62 mm. The critical coalescence concentration (CCC) was identified as 120 ppm. Gas velocity and wash water velocity significantly influenced bubble size, with gas holdup peaking at 27% at 1.08 cm/s a gas velocity. The bubble-rising velocity increased as the bubble size increased, indicating that the bubble size and bubble-rising velocity were proportional. The bubble surface area flux decreased linearly with increasing bubble size and was significantly affected by the gas velocity. A strong correlation (R2 = 0.86) between measured and calculated bubble sizes was achieved, with an average size of 0.64 mm and an estimation error of ±13%. The study demonstrated that bubble size and distribution could be effectively controlled under specific operational conditions (Jg = 0.65–1.3 cm/s, JW = 0.13–0.52 cm/s, frother = 30–120 ppm). These findings highlight the importance of optimizing key variables to enhance column stability, regime maintenance, and flotation performance.

Resumen

Abstract The response of beaches to typhoons has always been a hot topic at home and abroad. The study of beach changes during typhoons is helpful to deepen the understanding of beach evolution and is important for the coastal ecological environment. Based on the observation results of ten profiles and the sediment samples in Chudao before and after the typhoon Lekima, this article explored the response characteristics of the beach to the typhoon. The results showed that the study area was located on the right side of the typhoon’s forward path, and the double superposition of onshore waves and storm surge resulted in erosion along the beach. In order to alleviate the energy brought by storm waves, the beach was transformed into a more dissipated state. The mean particle size of the beach sediments was coarse on the whole, with poor sorting ability, and that in the wash zone was particularly obvious. The results showed that different profiles responded to Lekima in different ways: while the profiles of N01–N05 in the southwest changed little, those of N06–N10 in the northeast changed from the type of beach shoulder to the type of sandbank as a result of morphological differences in different profiles.

Resumen

AbstractObjective: The aim of the present study was to evaluate the relative bioavailability of two formulations containing 10 mg dapagliflozin in healthy Caucasian subjects under fasting conditions.Materials and Methods: Forty-eight healthy Caucasian subjects were enrolled in a single-dose, crossover, balanced, open label, randomized clinical trial, with two treatment, two periods and two sequences. The wash-out period was of 7 days and thirty-eight subjects completed both study periods. Each subject received a single dose of 10 mg dapagliflozin as the reference product Farxiga® (AstraZeneca Pharmaceuticals LP, USA) and the test product developed by Sun Pharmaceutical Industries, India. Dapagliflozin plasma levels were determined from blood samples collected in both study periods before and after dosing until 48 hours by using a validated LC-MS/MS method. For pharmacokinetic analysis of data, the non-compartmental method was used (Phoenix® WinNonlin 6.3). The statistical analysis was performed by SAS software 9.1.3 for the logarithmically transformed values of maximum plasma concentration and area under the curve.Results: The 90% confidence intervals for the evaluated pharmacokinetic parameters were found to be in the accepted interval for bioequivalence (80.00-125.00%).Conclusion: The 10 mg dapagliflozin immediate release tablet newly developed by Sun Pharmaceutical Industries, India, is bioequivalent with the reference product Farxiga® under fasted state of the subjects.

Resumen

The reproducibility of the use of sperm cells as vectors of foreign DNA in the genome of pigs was verified in the present study and the effectiveness of four different procedures for sperm treatment was assessed. For each gilt, approximately 6 x 10(6) ejaculated boar spermatozoa were incubated for 30 min in 1 mL TALP medium containing 3 micrograms of linearized pSV2CAT plasmid DNA. Before incubation, spermatozoa were treated in four experimental groups: (1) cells were stored at 16 degrees C for 24 h and then washed three times in TALP; (2) cells from the fresh, undiluted sperm-rich fraction of an ejaculate were used immediately after collection, following the same procedure as (1); (3) cells were treated as in (2) with an extra wash; and (4) incubation with DNA was performed in TALP medium supplemented with 0.5 mg mL(-1) poly-L-lysine hydrobromide. As determined by immunolocalization, plasmid DNA molecules were found to be associated with 12-17.1% spermatozoa, depending on sperm treatment. Of 35 inseminated gilts, 20 gave birth to a total of 126 piglets. None of the piglets showed sign of exogenous DNA incorporation in any of the tissues tested, as assessed by the polymerase chain reaction and Southern blot. The potential of modifying the pig genome through 'transformed' spermatozoa was not confirmed by these experiments.

Resumen

Epitope-specific antibodies to the M1 and M2 subunits of mammalian ribonucleotide reductase were prepared using peptides predicted to have a high antigenic index. Western blotting demonstrated that the anti-M1 antibody was specific for the 89-kilodalton M1 subunit (and its degradation fragments) and the anti-M2 antibody specifically recognized the 45-kilodalton M2 subunit. Both antibodies inhibited the CDP-reductase activity of the holoenzyme. Using these antibodies, both the M1 and M2 subunits were shown to be localized in the cytoplasm and in the nuclear regions of a number of cell types, including B77 avian sarcoma virus transformed NRK cells, T51B rat liver cells, 5123tc hepatoma cells, and rat liver cells in vivo. In addition, the M1 subunit was found to be localized as a halo around isolated rat liver nuclei. Biochemical analysis of the cytoplasmic fraction of liver cells and a Triton X-100 wash of nuclei from these cells confirmed the location of the enzyme activity in these cellular compartments. The M1 subunit appears to be glycosylated, as indicated by its retention on a Affi-Gel – concanavalin A affinity column. Therefore, in mammalian cells ribonucleotide reductase appears to be not only in the cytoplasm, but is also associated with the nuclear membrane or nuclear lamina. The activity of the enzyme in the membrane fraction changes dynamically during the cell cycle.Key words: replication, DNA, synthesis, glycosylation, liver.

Resumen

With the development of multimedia technology and the popularity of smartphones, the collection of multimedia information from various applications has rapidly grown. This information encompasses text, images, video, and audio compositions. This multimedia information has not only transformed the way we communicate and share content but has also posed new challenges and opportunities in fields such as data analysis, content creation, and information management. Consequently, multimedia education has become the focal point for research institutions and businesses. The modern solution faces two main challenges: expensive uptime and comparative speed. Therefore, this study first introduces a washing method called Permutation (OPH) to reduce expensive working time. Furthermore, the study explores innovative techniques to enhance the comparative speed of the modern solution, ultimately aiming to achieve a more efficient and cost-effective system. With the OPH, a permutation wash (GOPH) has been developed, along with several useful techniques to address pressure changes. This development is based on the fact that most multimedia files differ from one another. A new hashing method, known as Hierarchical Permutation Hash (HOPH), has been created to enhance productivity. Extensive testing with real multimedia files clearly demonstrates that HOPH is five to seven times faster than Minis' while maintaining the same level of accuracy. HOPH achieves this remarkable speed improvement by efficiently leveraging hierarchical structures in data, making it a promising solution for a wide range of multimedia applications.
