Common properties of the operator equations in ultrametric specrtal theory
Authors: Ettayb Jawad 
Published: March 2024

Let X and Y be two ultrametric Banach spaces over K. Let A,D ∈ B(X,Y) and B,C ∈ B(Y,X) such that ABA=ACA (resp. ACD=DBD and DBA=ACA). In this paper, the operator equation ABA=ACA is studied, and the common operator properties of AC-IY and BA-IX are described. In particular, it is proved that N(IY-AC) is complemented in Y if and only if N(IX-BA) is complemented in X. Moreover, the approach is generalized (i.e., CD=DBD and DBA=ACA) for considering relationships between the properties IY-AC and IX-BD. Finally, several illustrative examples are provided.

The main function of early childhood education is to be a place for children to process to develop themselves through their world, namely play. The state of the times and its development began to affect the perspective of thinking that in early childhood education institutions more applied play and learning. But nowadays early childhood education institutions are no longer playing while learning but have emphasized learning like elementary school children. Such things as children being forced to accept teaching that is not in accordance with their age is clearly not humanizing because the world of children is a world of play. Using a descriptive qualitative method, it can be concluded that in education, children are expected to feel freedom and also feel unbound by the opinions of other people, both educators and people in the scope of the child's own life, and students are also expected to be able to manage their own personalities with a sense of responsibility without violating existing moral and ethical rules. And where the achievement of humanistic learning in the realm of Christian Religious Education is to shape the child's personality so that the child achieves a change in attitude and is able to become a light in the community. The application of humanistic learning theory in early childhood in the frame of Christian faith can produce experiences that are holistic. with a focus on the needs and potential of children.AbstrakFungsi utama pendidikan anak usia dini adalah menjadi suatu wadah bagi anak untuk berproses mengembangkan dirinya melalui dunia mereka yaitu bermain. Keadaan zaman dan perkembangannya mulai memengaruhi perspektif berpikir yang pada lembaga pendidikan anak usia dini lebih diterapkan bermain dan belajar. Namun dewasa ini lembaga pendidikan anak usia dini bukan lagi bermain sambil belajar tetapi sudah menekankan belajar seperti layaknya anak sekolah dasar. Hal demikian seperti anak dipaksa untuk menerima pengajaran yang tidak sesuai dengan umurnya jelas tidak memanusiakan karena dunia anak adalah dunia bermain. Mengunkan metode kualitatif deskritif maka dapat disimpulkan bahwa Dalam Pendidikan anak diharapkan merasakan kebebasan dan juga merasakan ketidak terikatan oleh pendapat orang lain baik pendidik maupun orang-orang yang ada dalam lingkup kehidupan anak itu sendiri, dan anak didik juga diharapkan dapat mengatur kepribadian mereka sendiri dengan penuh rasa tanggung jawab tanpa melanggar aturan moral dan etika yang ada. Dan di mana capaian pembelajaran humanistik di ranah Pendidikan Agama Kristen untuk membentuk pribadi anak sehingga anak tersebut mencapai perubahan sikap dan mampu menjadi terang di dalam lingkungan Masyarakat. Penerapan teori belajar humanistik pada anak usia dini dalam bingkai iman Kristen dapat menghasilkan pengalaman yang bersifat holistik. dengan fokus pada kebutuhan dan potensi anak.

Published: March 2024

This study was developed through a comparative experimental design, using two groups, the first one the experimental group and the second one the control group, having as experimental units the students of the second semester of the career “Ingenieria Acuícola” of the Universidad Technical de Machala of the academic periods D1 and D2 of the school year 2017-2018. The course was taught to the experimental group using the “constructivist method” considering the different learning styles of the students and complementing it with the mathematical computational laboratory practices. With the results it was possible to contrast the hypothesis that the teaching of differential calculus, practiced systematically and complemented with computational tools is able to promote significant learning to its students.

Published: March 2024

The process of determining costs and prices in Make-to-Order (MTO) companies is generally complex because they make products according to special orders. Speed, accuracy, and consistency are necessary for a successful pricing estimation. Custom batik price, along with anticipated production time, is still done manually at the moment. Integration of design and manufacturing with computer-based was needed to produce custom batik products. This paper aims to develop a pricing decision system model for CAD custom batik motifs and written batik CNC machines used in the production processes. Customers can adapt their budgets by changing the parameters to suit their requirements and capacities using various price options. This model helps the customers to make buying decisions. The data and information were gathered through interviews, observations, and a literature review. The pricing decision system has been determined using the job order costing method, where prices are collected for each order separately according to the demand's identity or the order's cost. The system was developed through the prototyping process. This research has created a framework for determining the price for custom design batik based on 4 (four) parameters: the motif, the number of colors used, the type of color used, and the type (size) of the fabric used. Also, incorporating more comprehensive parameters has improved the system (motif size, number of colors, color selection, coloring techniques, and fabric sizes). The outcome of the calculation simulation demonstrates that the constructed model successfully calculated the unit price of products with accuracy. It shows that the system can be used in practical situations.

Published: March 2024

The Internet of Things (IoT) has revolutionized the traditional Internet, pushing past its former boundaries by implementing smart linked gadgets. The IoT is steadily becoming a staple of everyday life, having been implemented into various diverse applications, such as cities, smart homes, and transportation. However, despite the technological advancements that the IoT brings, various new security risks have also been introduced due to the development of new types of attacks. This prevents current intelligent IoT applications from adaptively learning from other intelligent IoT applications, which leaves them in a volatile state. In this paper, we conducted a structured literature review (SLR) on Smart Home's IoT attack detection using machine learning and deep learning. Four journal databases were used to perform this review: IEEE, Science Direct, Association for Computing Machinery (ACM), and SpringerLink. Sixty articles were selected and studied, where we noted the various patterns and techniques present in the framework of the selected research. We also took note of the different machine learning and deep learning methods, the types of attacks, and the Network layers present in Smart Home. By conducting an SLR, we analyzed the numerous techniques of IoT attack detection for smart homes proposed by various theoretical studies. We enhanced the studied literature by proposing a new solution for better IoT attack detection in smart homes.

Frequently Asked Questions (FAQs) are extensively studied in general domains like the medical field, but such frameworks are lacking in domains such as software engineering and open-source communities. This research aims to bridge this gap by establishing the foundations of an automated FAQ Generation and Retrieval framework specifically tailored to the software engineering domain. The framework involves analyzing, ranking, performing sentiment analysis, and summarization techniques on open forums like StackOverflow and GitHub issues. A corpus of Stack Overflow post data is collected to evaluate the proposed framework and the selected models. Integrating state-of-the-art models of string-matching models, sentiment analysis models, summarization models, and the proprietary ranking formula proposed in this paper forms a robust Automatic FAQ Generation and Retrieval framework to facilitate developers' work. String matching, sentiment analysis, and summarization models are evaluated, and F1 scores of 71.31%, 74.90%, and 53.4% were achieved. Given the subjective nature of evaluations in this context, a human review is used to further validate the effectiveness of the overall framework, with assessments made on relevancy, preferred ranking, and preferred summarization. Future work includes improving summarization models by incorporating text classification and summarizing them individually (Kou et al, 2023), as well as proposing feedback loop systems based on human reinforcement learning. Furthermore, efforts will be made to optimize the framework by utilizing knowledge graphs for dimension reduction, enabling it to handle larger corpora effectively
Towards an understanding of apoptosis detection by SYTO dyes
Authors: Wlodkowic Donald , Skommer Joanna , Pelkonen Jukka 
Published: January 2007

AbstractBackground:SYTO probes are gaining momentum as reliable and easy to use markers of apoptotic cell death, but the phenomenon underlying reduced SYTO fluorescence in apoptotic cells as compared with normal cells is still not fully elucidated. Herein, we attempt to provide further insights into mechanisms of reduced SYTO16 fluorescence during apoptosis.Methods:Human follicular lymphoma cell lines were subjected to diverse apoptotic and oncotic stimuli with subsequent multiparametric flow cytometric and fluorescence imaging analysis. SYTO green (SYTO11‐16), TMRM, PI, 7AAD, and Hoechst 33342 probes were applied for multivariate analysis of temporal sequence of apoptotic events. Sorting of cells differing in the level of SYTO16 fluorescence and subsequent characterization of obtained subpopulations were also performed.Results:Loss of SYTO16 fluorescence (SYTOlow/PI+ events) has been observed in cells exposed to oncotic stimuli, whereas SYTOhigh/PI+ events did not prevail at any treatment scenario. We tracked similarities and discrepancies between SYTO16 and TMRM probes. Often, SYTO16 and TMRM exhibited the same staining profiles, as loss of their fluorescence was detected in a single cell population. However, both mitochondrial uncoupler FCCP and a small‐molecule Bcl‐2 inhibitor, HA14‐1, appeared to induce distinct staining profiles of SYTO16 and TMRM, with the decrease in TMRM fluorescence preceding the loss of SYTO16 fluorescence. Importantly, in both cases (FCCP and HA14‐1) the decrease of SYTO16 fluorescence was blocked by pharmacological inhibition of caspases (with z‐VAD‐fmk).Conclusions:The data demonstrate that loss of SYTO16 is caspase‐dependent, as is not a mere indicator of Δψm dissipation. Commonly observed similarities between SYTO and TMRM may stem from the fast kinetics of apoptotic events once cell death is initiated. © 2007 International Society for Analytical Cytology.
An idealised model of turbulent dispersion: one rectangular pulse initial condition
Authors: Mole Nils , Yeun Hyun Ku 
Published: January 2007

AbstractWe examine an idealised model of turbulent dispersion which was introduced by Zimmerman and Chatwin. It involves deterministic diffusion in a periodic one‐dimensional domain, for a specified initial concentration field. A stochastic element is introduced by sampling at random across the domain, equivalent to random advection by a velocity which does not vary spatially. We consider initial conditions consisting of a single rectangular pulse, displaced a distance X0 from the centre of the domain. We present numerical results for the dependence of the variance, skewness, kurtosis and probability density function (pdf) of concentration on X0 and on time, and we derive the large time asymptotic forms for these quantities. At large time, the pdf is inevitably bimodal, with the peaks at the smallest and largest concentrations. To allow for a range of possible distances between strands of high concentration, as would be expected in a real turbulent flow, we suggest a new model pdf for concentration, obtained by averaging over different values of X0. For a uniform distribution of X0 values, we show that this gives a unimodal concentration pdf at large time, with the peak at the mean concentration. Copyright © 2007 John Wiley & Sons, Ltd.
Synthesis and characterization of some novel triphenylarsenic(V) derivatives of monofunctional bidentate 2,2‐disubstituted benzothiazoline ligands

AbstractA series of triphenylarsenic(V) derivatives Ph3As(OPri)[SC6H4N:C(R)CH2C(O)R′] have been synthesized by the reactions of triphenylarsenic(V)‐ isoproproxide, Ph3As(OPri)2 with the corresponding 2,2‐disubstituted benzothiazolines of the type ${\rm H\overline{NC_6 H_4 S}C(R)CH_2C(O)R'}$ (where R = CH3, R′ = CH3(1); R = CH3, R′ = C6H5(2); R = CH3, R′ = 4‐CH3C6H4(3); R = CH3, R′ = 4‐ClC6H4(4); and R = CF3, R′ = C6H5(5)) in equimolar ratio in refluxing benzene solution. Molecular weight measurements of these complexes show their monomeric nature in solution. Characterization of these compounds using elemental analyses, molecular weight measurements, and spectral studies (IR as well as NMR (1H and 13C)) shows the monofunctional bidentate nature of the ligands and a hexacoordination around the central arsenic atom in these organoarsenic(V) derivatives. © 2007 Wiley Periodicals, Inc.

Effect of unitization on associative recognition in amnesia
Authors: Quamme Joel R. , Yonelinas Andrew P. , Norman Kenneth A. 
Published: January 2007

AbstractWe examined how associative recognition performance in amnesic patients is mediated by use of a unitized (i.e., holistic) encoding strategy, and the degree to which the unitization effect is related to sparing of familiarity‐based recognition. Participants studied word pairs as either separate lexical units in sentences (i.e., nonunitized) or as compounds (unitized). Under standard recognition instructions, normal controls and patients with left‐temporal lobe damage (previously determined to have impairments in both recollection and familiarity) showed no difference for unitized and nonunitized pairs, whereas hypoxics (previously determined to have impaired recollection but relatively preserved familiarity) showed an advantage of unitized over nonunitized pairs. This effect was reproduced in normal healthy participants under instructions to restrict responses to judgments of familiarity. The results indicate that unitization may mediate the degree of associative recognition impairment exhibited by some amnesic patients, and that the effect is related to preserved familiarity capacity. The relevance of the results to the debate over the importance of the hippocampus in memory for associations is discussed. © 2007 Wiley‐Liss, Inc.
Increasing the sensitivity of δ13C and δ15N abundance measurements by a high sensitivity elemental analyzer connected to an isotope ratio mass spectrometer
Authors: Hansen T. , Sommer U. 
Published: January 2007

AbstractA common elemental analyzer system connected to a temperature‐controlled gas chromatography (GC) column and coupled to an isotope ratio mass spectrometer was improved to decrease the determination limit for a simultaneous stable isotope ratio measurement of nitrogen and carbon dioxide. The additional use of a special ashtray system to collect the combustion residuals permitted more time‐efficient work. These modifications to the elemental analyzer allowed precise measurements to be made down to 1.5 µg nitrogen and 10 µg carbon for stable isotope analysis. Low system background values and an acceptable signal‐to‐noise ratio have made an additional blank correction for these low sample measurements unnecessary. We provide a precision of this stable isotope analysis for lowest amounts of 1.2–2 µg nitrogen with a standard deviation of ±0.496‰ (n = 27) and for 8.2–15 µg carbon with a standard deviation of ±0.257‰ (n = 31) across different sample runs under stipulated conditions. This application can be established in an automatic mode without cryofocusing procedures. Copyright © 2007 John Wiley & Sons, Ltd.
The Earliest Motets: Music and Words
Authors: Smith Norman E. 
Published: January 2007

The birth of a genre surely is one of the most fascinating occurrences in the history of music, and no genre of medieval music had a more interesting birth than the motet. Study of the motet in modern times found special impetus and direction in 1898 when Wilhelm Meyer announced his discovery of the origin of the motet in the discant clausulae of the Notre Dame organa. Demonstrating the musical identity of certain Latin motets and discant clausulae, he concluded that the motet arose through the addition of Latin texts to the melismatic upper voices of the two-voice clausulae and was thereby able to explain for the first time the previously baffling and unprecedented verse structures of many motet texts. In doing so, he at the same time made it clear that he understood the French motet to be of later origin than the Latin and brushed aside special questions concerning the French type, such as, for example, its most provocative feature: its characteristic use of refrains. How was one to understand the presence of refrains in a French motet supposedly derived from a sacred, liturgical model? This and other difficult questions refused to disappear, and they continued to be raised from time to time, but Meyer's explanation of the origin of the motet gained general acceptance, most decisively and influentially from Friedrich Ludwig. All of Ludwig's writings on the motet bespeak his endorsement of Meyer's position, but nowhere more explicitly than in the Repertorium:These compositions [discant clausulae] were still more important by virtue of the fact that they served in rather large numbers as musical sources of motets, at first for Latin motets and later, although in more limited numbers, also for French motets - a fact, first recognized for the Latin motets by Wilhelm Meyer in 1898 (Der Ursprung des Motetts), claiming central importance for the history of music about 1200.
Sterndale Bennett's Lost Piano Concerto Found
Authors: Williamson Rosemary 
Published: January 2007

I have as I before stated, not yet played this season in the great Concerts [at the Gewandhaus] because I preferred to wait until I was just leaving Leipzig, and had finished all my compositions for the Publisher, therefore on the 3rd. March I will if possible play a new Concerto which I have in hand.THIS, in a letter to Mary Anne Wood dated 7 February 1842, is the earliest specific mention of Bennett's last piano concerto, which was never published and for many years was missing. Only a ‘tantalising fragment’ of a two-piano reduction made by the composer's son and biographer, J. R. Sterndale Bennett, was known to researchers. Autograph manuscripts of two versions of the work, and two sets of orchestral parts copied for different performances, have recently come to light during the present author's research on Bennett. The discovery enables a fresh assessment to be made of an ‘unpublished work of outstanding importance’ by a composer of relatively few large-scale pieces, composed at the end of his most creative period and when he was arguably at the height of his powers. It also presents the possibility of the concerto's performance and publication, 150 years after its conception. A summary of all the sources now known is given in Table 1.
Music in War - Time
Authors: Colles H. C. 
Published: January 2007

Musicians have been conscious lately that they have become less interesting to their fellows than they normally are, and many of us find—even though we may be ashamed to confess it—that music itself interests us less than it was used to do:
Personally I have been made aware of this in many ways;
(1)By the extreme difficulty I find in getting a single word about music into a certain daily newspaper, which only a few months ago insisted upon my supplying it with a column a day; and since that paper has been described as one for “all thinking men and women,” I can only suppose that men and women are now not thinking much about music;(2)I find it in the difficulty I have in concentrating my own attention upon the course of the music on the comparatively rare occasions when I enter a concert room;(3)And in the fact that yesterday when I was reading a book on the harmony of Arnold Schönberg, the only emotion it raised was a vague hope that Schönberg might be somewhere in the German trenches.
