Abstract:

In this paper, we design and develop a new class of linear algebraic codes defined as soft linear algebraic codes using soft sets. The advantage of using these codes is that they have the ability to transmit m-distinct messages to m-set of receivers simultaneously. The methods of generating and decoding these new classes of soft linear algebraic codes have been developed. The notion of soft canonical generator matrix, soft canonical parity check matrix, and soft syndrome are defined to aid in construction and decoding of these codes. Error detection and correction of these codes are developed and illustrated by an example.

Abstract:

The main focus of this paper is to analyze the algebraic structure of constacyclic codes over the ring R=Fp+w1Fp+w2Fp+w22Fp+w1w2Fp+w1w22Fp, where w12−α2=0, w1w2=w2w1, w23−β2w2=0, and α,β∈Fp∖{0}, for a prime p. We begin by introducing a Gray map defined over R, which is associated with an invertible matrix. We demonstrate its advantages over the canonical Gray map through some examples. Finally, we create new and improved quantum codes from constacyclic codes over R using Calderbank–Shore–Steane (CSS) construction.

Abstract:

AbstractThis paper presents the semiotics of passions. It first retraces the establishment and evolution of this theory, and sets out its objectives and issues, especially its relationship to tensivity. Next, it highlights devices suggested for approaching textual manifestations of passions, notably the canonical schema of passions and codes of passions: perspective codes, modal codes, somatic codes, rhythmic and aspectual codes, perceptive and figurative codes. Finally, it underlines the importance of concrete analyses in this field, by situating them alongside cultural studies.

Full text

Abstract:

The development of an efficient solution procedure for the detection of isomorphism and canonical numbering of vertices of colored graphs is introduced. This computer-based algorithm for colored graphs is formed by extending the standard code approach developed earlier for the canonical numbering of simple noncolored graphs, which fully utilizes the capabilities of symmetry analysis of such noncolored graphs. Its application to various kinematic chains and mechanisms is investigated with the aid of examples. The method never failed to produce unique codes, and is also found to be robust and efficient. Using this method, every kinematic chain and mechanism, as well as path generators and function generators, will have their own unique codes and a corresponding canonical numbering of their respective links. Thus, based on its efficiency and applicability, this method can be used as a universal standard code for identifying isomorphisms, as well as for enumerating nonisomorphic kinematic chains and mechanisms.

Abstract:

The brain processes information about the environment via neural codes. The neural ideal was introduced recently as an algebraic object that can be used to better understand the combinatorial structure of neural codes. Every neural ideal has a particular generating set, called the canonical form, that directly encodes a minimal description of the receptive field structure intrinsic to the neural code. On the other hand, for a given monomial order, any polynomial ideal is also generated by its unique (reduced) Gröbner basis with respect to that monomial order. How are these two types of generating sets — canonical forms and Gröbner bases — related? Our main result states that if the canonical form of a neural ideal is a Gröbner basis, then it is the universal Gröbner basis (that is, the union of all reduced Gröbner bases). Furthermore, we prove that this situation — when the canonical form is a Gröbner basis — occurs precisely when the universal Gröbner basis contains only pseudo-monomials (certain generalizations of monomials). Our results motivate two questions: (1) When is the canonical form a Gröbner basis? (2) When the universal Gröbner basis of a neural ideal is not a canonical form, what can the non-pseudo-monomial elements in the basis tell us about the receptive fields of the code? We give partial answers to both questions. Along the way, we develop a representation of pseudo-monomials as hypercubes in a Boolean lattice.

Abstract:

Finite-element/boundary-element codes are widely used to analyze the response of marine structures to underwater explosions. An important step in verifying the correctness and accuracy of such codes is the comparison of code-generated results for canonical problems with corresponding analytical or semianalytical results. At the present time, such comparisons rely on hardcopy results presented in technical journals and reports. This article describes a computer program available from SAVIAC that produces user-selected numerical results for a step-wave-excited spherical shell submerged in and (optionally) filled with an acoustic fluid. The method of solution employed in the program is based on classical expansion of the field quantities in generalized Fourier series in the meridional coordinate. Convergence of the series is enhanced by judicious application of modified Cesàro summation and partial closed-form solution.

Full text

Abstract:

The promise of high-rate low-density parity check (LDPC) codes to substantially reduce the overhead of fault-tolerant quantum computation depends on constructing efficient, fault-tolerant implementations of logical gates on such codes. Transversal gates are the simplest type of fault-tolerant gate, but the potential of transversal gates on LDPC codes has hitherto been largely neglected. We investigate the transversal gates that can be implemented in hypergraph product codes, a class of LDPC codes. Our analysis is aided by the construction of a symplectic canonical basis for the logical operators of hypergraph product codes, a result that may be of independent interest. We show that in these codes transversal gates can implement Hadamard (up to logical SWAP gates) and control-Z on all logical qubits. Moreover, we show that sequences of transversal operations, interleaved with error correction, allow implementation of entangling gates between arbitrary pairs of logical qubits in the same code block. We thereby demonstrate that transversal gates can be used as the basis for universal quantum computing on LDPC codes, when supplemented with state injection.

Abstract:

<abstract><p>To elucidate the combinatorial architecture of neural codes, the neural ideal $ J_C $, an algebraic object, was introduced. Represented in its canonical form, $ J_C $ provides a succinct characterization of the inherent receptive field architecture within the code. The polynomials in $ J_C $ are also instrumental in determining the relationships among the neurons' receptive fields. Consequently, the computation of the collection of canonical forms is pivotal. In this paper, based on the study of relations between pseudo-monomials, the authors present a computationally efficient iterative algorithm for the canonical forms of the neural ideal. Additionally, we introduce a new relationship among the neurons' receptive fields, which can be characterized by if-and-only-if statements, relating both to $ J_C $ and to a larger ideal of a code $ I(C) $.</p></abstract>

Abstract:

The article considers an approach to the modification of manipulative impulse sequences based on Barker codes. It is proposed to change the structure of the encoded pulses by the duration of the elementary message, taking into account the change in the duty cycle of their repetition while maintaining the total average energy. Numerical relations are obtained that determine the spectral and temporal parameters for a seven-element pulse sequence, with an increase in the pulse repetition rate by two and three times. Numerical values are calculated that determine the ratio of the duration of the peaks of the cross-correlation functions between the modified and canonical forms of pulse sequences. Reasonable estimates are presented that characterize the increase in the resolution of the peaks of the cross-correlation functions by 4.43 times in the transition to the proposed modified structure of the pulse sequence.

Abstract:

Image Compression techniques have become a very important subject with the rapid growth of multimedia application. The main motivations behind the image compression are for the efficient and lossless transmission as well as for storage of digital data. Image Compression techniques are of two types; Lossless and Lossy compression techniques. Lossy compression techniques are applied for the natural images as minor loss of the data are acceptable. Entropy encoding is the lossless compression scheme that is independent with particular features of the media as it has its own unique codes and symbols. Huffman coding is an entropy coding approach for efficient transmission of data. This paper highlights the fractal image compression method based on the fractal features and searching and finding the best replacement blocks for the original image. Canonical Huffman coding which provides good fractal compression than arithmetic coding is used in this paper. The result obtained depicts that Canonical Huffman coding based fractal compression technique increases the speed of the compression and has better PNSR as well as better compression ratio than standard Huffman coding.

Abstract:

ABSTRACT: As a consequence of canonical accommodations on the part of the Apostolic See, both the Eastern Catholic and Latin Churches in the United States are now being served by married presbyters, some with families. The provisions in both codes are general and necessitate ad hoc decision-making by bishops, leading to potential inequity and injustice. To address this, a system of best practices is needed for evaluating candidates; determining appropriate offices and functions for married presbyters; defining the role of spouses in the formation, ordination, and appointment process; and addressing issues of remuneration, housing, and benefits. This study aims to clarify certain canonical principles, identify key issues, and propose potential options.

Abstract:

The corpus of Jewish legal writings contains many discussions of economic issues and ideas. Yet, aside from a small group of scholars, historians of economics have tended to ignore the texts of Jewish law. As Ephraim Kleiman (1997) points out, the sheer size and inaccessibility of the Jewish law corpus presents a major barrier. Economic ideas are scattered across a vast amount of material. The canonical text of Jewish law is the Talmud, which spans 2,700 folio pages and two million words. Hundreds of commentaries have been written on the Talmud (or parts of it). There are three major codes of Jewish Law (based on the Talmud and selected commentaries), plus commentaries on the codes and lesser known codes (based on the major codes). About one million responsa (questions and answers in Jewish law) are known to exist; these are collected in hundreds of books. Today, new commentaries and responsa appear each year, in addition to multiple rabbinic journals. In order to understand these materials, the scholar must be well versed in Hebrew, Aramaic, and the reading of the Talmud.

Full text

Abstract:

SUMMARY Thermoelastic attenuation is similar to wave-induced fluid-flow attenuation (mesoscopic loss) due to conversion of the fast P wave to the slow (Biot) P mode. In the thermoelastic case, the P- and S-wave energies are lost because of thermal diffusion. The thermal mode is diffusive at low frequencies and wave-like at high frequencies, in the same manner as the Biot slow mode. Therefore, at low frequencies, that is, neglecting the inertial terms, a mathematical analogy can be established between the diffusion equations in poroelasticity and thermoelasticity. We study thermoelastic dissipation for spherical and cylindrical cavities (or pores) in 2-D and 3-D, respectively, and a finely layered system, where, in the latter case, only the Grüneisen ratio is allowed to vary. The results show typical quality-factor relaxation curves similar to Zener peaks. There is no dissipation when the radius of the pores tends to zero and the layers have the same properties. Although idealized, these canonical solutions are useful to study the physics of thermoelasticity and test numerical algorithm codes that simulate thermoelastic dissipation.

Abstract:

Methods of path integrals are used to develop multi-factor probabilities of bid-ask variables to be used in high-frequency trading (HFT). Adaptive Simulated Annealing (ASA) is used to fit the nonlinear forms, so developed to a day of BitMEX tick data. Maxima algebraic code is used to develop the path integral codes into C codes, and a sampling code is used for the fitting process. After these fits, the resultant C code is very fast and useful for forecasting upcoming ‘ask’, bid, midprice, etc., when narrow and wide windows of incoming data are used. A bonus is the availability of canonical momenta indicators (CMI) useful to forecast direction and strengths of these variables.

Abstract:

AbstractThe paper shows how the Scott–Koymans theorem for the untyped λ-calculus can be extended to the differential λ-calculus. The main result is that every model of the untyped differential λ-calculus may be viewed as a differential reflexive object in a Cartesian-closed differential category. This extension of the Scott–Koymans theorem depends critically on unraveling the somewhat subtle issue of which idempotents can be split so that differential structure lifts to the idempotent splitting.The paper uses (total) Turing categories with “canonical codes” as the basic categorical semantics for the λ-calculus. It develops the main result in a modular fashion by showing how to add left-additive structure to a Turing category, and then – on top of that – differential structure. For both levels of structure, it is necessary to identify how “canonical codes” must behave with respect to the added structure and, furthermore, how “universal objects” must behave. The latter is closely tied to the question – which is the crux of the paper – of which idempotents can be split while preserving the differential structure of the setting.This paper is the full version of a conference paper and includes the proofs which were omitted from that version due to page-length restrictions.

Besides the very good FER/SNR performance, the TBTC present several other advantages that recommend them: an effect error floor low, latency diminution, more compact blocks lower delay caused by interleaving, the possibility to connect the encoder TBTC to modulation blocks of higher order.

Abstract:

This study was embarked to examine the performance evaluation of canonical correlation and generalized canonical correlation analysis with some continuous distributed data (Gamma, Gaussian, Exponential and Beta). The objectives of the study were to: ascertain if the anthropometric indicators of patients were correlated; ascertain if there is any relationship between vital signs and anthropometric dimensions of patients; obtain the relative efficiency of CCA and GCCA techniques for four continuous distributed simulated data; and determine the model performance adequacy of CCA and GCCA techniques. Real life medical data set was used, consisting of three response variables (Respiration rate, heart rate, temperature) named the vital signs and three predictor variables (Hip circumference, weight, height) named anthropometric dimensions. The study employed the real life data set to simulate data of sample sizes 15, 30, 45, 60, 100, 120, 140, 160, 400, 600, 800 and 1000 for the four continuous distributions. A computer programming language codes were written via R-Studio package to solve the numerous numerical problems in this study. The result of the study revealed that anthropometric dimensions, being the independent variables were not correlated, which implied that there was no symptom of multicollinearity using the Eigen values/condition index technique. In addition, there was significant relationship between vital signs and anthropometric dimensions of patients using Wilks’ Lambda, Hotelling-Lawley Trace, Pillai’s Bartlett Trace and Roy’s Largest Root multivariate statistics. The adequacy of the CCA and GCCA was evaluated using Wilcoxon rank sum test; and the result revealed that GCCA was more efficient than that of CCA for the Gamma and Beta distributed data, while for Gaussian and Exponential distributed data, the relative efficiency of the CCA and GCCA was the same.

By integrating the two fields artificially kept apart, the authors endeavour to show how the resulting synergy could shed new light on the study of passions.

Abstract:

Recent investigations on rotation invariance for 3D point clouds have been devoted to devising rotation-invariant feature descriptors or learning canonical spaces where objects are semantically aligned. Examinations of learning frameworks for invariance have seldom been looked into. In this work, we review rotation invariance (RI) in terms of point cloud registration (PCR) and propose an effective framework for rotation invariance learning via three sequential stages, namely rotation-invariant shape encoding, aligned feature integration, and deep feature registration. We first encode shape descriptors constructed with respect to reference frames defined over different scales, e.g., local patches and global topology, to generate rotation-invariant latent shape codes. Within the integration stage, we propose an Aligned Integration Transformer (AIT) to produce a discriminative feature representation by integrating point-wise self- and cross-relations established within the shape codes. Meanwhile, we adopt rigid transformations between reference frames to align the shape codes for feature consistency across different scales. Finally, the deep integrated feature is registered to both rotation-invariant shape codes to maximize their feature similarities, such that rotation invariance of the integrated feature is preserved and shared semantic information is implicitly extracted from shape codes. Experimental results on 3D shape classification, part segmentation, and retrieval tasks prove the feasibility of our framework. Our project page is released at: https://rotation3d.github.io/.

Abstract:

Of late, image compression has become crucial due to the rising need for faster encoding and decoding. To achieve this objective, the present study proposes the use of canonical Huffman coding (CHC) as an entropy coder, which entails a lower decoding time compared to binary Huffman codes. For image compression, discrete wavelet transform (DWT) and CHC with principal component analysis (PCA) were combined. The lossy method was introduced by using PCA, followed by DWT and CHC to enhance compression efficiency. By using DWT and CHC instead of PCA alone, the reconstructed images have a better peak signal-to-noise ratio (PSNR). In this study, we also developed a hybrid compression model combining the advantages of DWT, CHC and PCA. With the increasing use of image data, better image compression techniques are necessary for the efficient use of storage space. The proposed technique achieved up to 60% compression while maintaining high visual quality. This method also outperformed the currently available techniques in terms of both PSNR (in dB) and bit-per-pixel (bpp) scores. This approach was tested on various color images, including Peppers 512 × 512 × 3 and Couple 256 × 256 × 3, showing improvements by 17 dB and 22 dB, respectively, while reducing the bpp by 0.56 and 0.10, respectively. For grayscale images as well, i.e., Lena 512 × 512 and Boat 256 × 256, the proposed method showed improvements by 5 dB and 8 dB, respectively, with a decrease of 0.02 bpp in both cases.

Abstract:

Opinions about the authenticity/inauthenticity of the disputed canonical letters of Paul are framed within some of the basic ethical codes associated with the upper echelons of the London art trade, where careful consideration is given to the descriptions of objects of uncertain origin and status when they are put on sale. Acting responsibly when conclusions are inconclusive; having regard for the importance of maintaining an honest reputation; and valuing the opinions of experts are as important for Bible teachers as they are for the trade.

Abstract:

Insulin receptor substrates 1 and 2 (IRS-1 and IRS-2) are signaling adaptor proteins that participate in canonical pathways, where insulin cascade activation occurs, as well as in non-canonical pathways, in which phosphorylation of substrates is carried out by a diverse array of receptors including integrins, cytokines, steroid hormones, and others. IRS proteins are subject to a spectrum of post-translational modifications essential for their activation, encompassing phosphorylation events in distinct tyrosine, serine, and threonine residues. Tyrosine residue phosphorylation is intricately linked to the activation of the insulin receptor cascade and its interaction with SH2 domains within a spectrum of proteins, including PI3K. Conversely, serine residue phosphorylation assumes a different function, serving to attenuate the effects of insulin. In this review, we have identified over 50 serine residues within IRS-1 that have been reported to undergo phosphorylation orchestrated by a spectrum of kinases, thereby engendering the activation or inhibition of different signaling pathways. Furthermore, we delineate the phosphorylation of over 10 distinct tyrosine residues at IRS-1 or IRS-2 in response to insulin, a process essential for signal transduction and the subsequent activation of PI3K.

Abstract:

Phytochromes give rise to the largest photosensor family known to date. However, they are underrepresented in the Protein Data Bank. Plant, cyanobacterial, fungal and bacterial phytochromes share a canonical architecture consisting of an N-terminal photosensory module (PAS2–GAF–PHY domains) and a C-terminal variable output module. The bacteriumXanthomonas campestrispv.campestris, a worldwide agricultural pathogen, codes for a single bacteriophytochrome (XccBphP) that has this canonical architecture, bearing a C-terminal PAS9 domain as the output module. Full-length XccBphP was cloned, expressed and purified to homogeneity by nickel–NTA affinity and size-exclusion chromatography and was then crystallized at room temperature bound to its cofactor biliverdin. A complete native X-ray diffraction data set was collected to a maximum resolution of 3.25 Å. The crystals belonged to space groupP43212, with unit-cell parametersa=b= 103.94,c= 344.57 Å and a dimer in the asymmetric unit. Refinement is underway after solving the structure by molecular replacement.

Abstract:

Existing 3D-aware facial generation methods face a dilemma in quality versus editability: they either generate editable results in low resolution, or high-quality ones with no editing flexibility. In this work, we propose a new approach that brings the best of both worlds together. Our system consists of three major components: (1) a 3D-semantics-aware generative model that produces view-consistent, disentangled face images and semantic masks; (2) a hybrid GAN inversion approach that initializes the latent codes from the semantic and texture encoder, and further optimizes them for faithful reconstruction; and (3) a canonical editor that enables efficient manipulation of semantic masks in canonical view and produces high-quality editing results. Our approach is competent for many applications, e.g. free-view face drawing, editing and style control. Both quantitative and qualitative results show that our method reaches the state-of-the-art in terms of photorealism, faithfulness and efficiency.

Full text

Abstract:

We consider the storage–retrieval rate trade-off in private information retrieval (PIR) systems using a Shannon-theoretic approach. Our focus is mostly on the canonical two-message two-database case, for which a coding scheme based on random codebook generation and the binning technique is proposed. This coding scheme reveals a hidden connection between PIR and the classic multiple description source coding problem. We first show that when the retrieval rate is kept optimal, the proposed non-linear scheme can achieve better performance over any linear scheme. Moreover, a non-trivial storage-retrieval rate trade-off can be achieved beyond space-sharing between this extreme point and the other optimal extreme point, achieved by the retrieve-everything strategy. We further show that with a method akin to the expurgation technique, one can extract a zero-error PIR code from the random code. Outer bounds are also studied and compared to establish the superiority of the non-linear codes over linear codes.

Full text

Abstract:

One of the biggest developments in mixed methods research has been the conceptualization of one or more analysis types associated with one tradition (e.g., qualitative analysis) being used to analyze data associated with a different tradition (e.g., quantitative data)—what Onwuegbuzie and Combs (2010) called crossover mixed analyses, or, more simply, crossover analyses. A hallmark of crossover analyses is the notion of quantitizing, which, in its simplest form, involves converting qualitative data into numerical forms that can be analyzed statistically. The focus on quantitizing has been on descriptive-based quantitizing approaches such as counting the occurrence of emergent themes. Unfortunately, scant guidance exists on inferential-based quantitizing, which refers to the quantitizing of qualitative data for the purpose of prediction or estimation (Onwuegbuzie, in press). Although recent literature has emerged on a few inferential-based quantitizing approaches (i.e., multiple linear regression analysis, structural equation modeling, hierarchical linear modeling), there still remains some general linear model analyses for which mixed methods researchers, in pursuit of conducting crossover analyses, can benefit from guidelines. One such analysis is canonical correlation analysis. Its importance stems from the fact that the analysis of qualitative data typically yields multiple patterns of meaning (e.g., codes, themes), which then can be correlated with other available variables (e.g., demographic variables, personality variables, affective variables) via the use of canonical correlation analysis. Therefore, the purpose of this article is (a) to describe canonical correlation analysis and (b) to illustrate how canonical correlation analyses can serve as an inferential-based quantitizing using a heuristic example.

Abstract:

In this work, the author introduces such a historical monument as the Code of Theodosius into the scientific circulation of branches of law of the criminological cycle. Against the background of the historical events that determine this act of systematization, the canonical segment of the Code is studied and its influence on the origin and development of criminal law is revealed in the inextricable connection between the activities of authoritative representatives of legal doctrine and the legislator. It is demonstrated how criminal law concepts, categories and institutions arose in the depths of church law, which are still in demand at the moment. The historical process of the formation of the systematization of normative material in Roman law, which went through the formation from the incorporation of private lawyers to the official codification carried out on behalf of the highest state bodies of the empire, is studied. Attention is paid to such predecessors of the Code of Theodosius as the codes of Gregorian and Hermogenian, and the influence of the Code of Theodosius on the further process of systematization of Roman law, reflected in the reforms of Justinian, is illustrated. In his work, the author emphasized the analysis of the canonical component of the historical and legal monument under study, based on the position that secular and canonical criminal law of the designated period in their unity constituted a common legal space. The article offered to the readers continued the cycle of author’s publications on the history of canonical criminal law.

ObjectiveTo assess the diagnostic Read code usage for 18 conditions by examining their frequency and diversity in UK primary care between 2000 and 2013.DesignPopulation-based cohort studySetting684 UK general practices contributing data to the Clinical Practice Research Datalink (CPRD) GOLD.ParticipantsPatients with clinical codes for at least one of asthma, chronic obstructive pulmonary disease, diabetes, hypertension (HT), coronary heart disease, atrial fibrillation (AF), heart failure, stroke, hypothyroidism, chronic kidney disease, learning disability (LD), depression, dementia, epilepsy, severe mental illness (SMI), osteoarthritis, osteoporosis and cancer.Primary and secondary outcome measuresFor the frequency ranking of clinical codes, canonical correlation analysis was applied to correlations of clinical code usage of 1, 3 and 5 years. Three measures of diversity (Shannon entropy index of diversity, richness and evenness) were used to quantify changes in incident and total clinical codes.ResultsOverall, all examined conditions, except LD, showed positive monotonic correlation. HT, hypothyroidism, osteoarthritis and SMI codes’ usage had high 5-year correlation. The codes’ usage diversity remained stable overall throughout the study period. Cancer, diabetes and SMI had the highest richness (code lists need time to define) unlike AF, hypothyroidism and LD. SMI (high richness) and hypothyroidism (low richness) can last for 5 years, whereas cancer and diabetes (high richness) and LD (low richness) only last for 2 years.ConclusionsThis is an under-reported research area and the findings suggest the codes’ usage diversity for most conditions remained overall stable throughout the study period. Generated mental health code lists can last for a long time unlike cardiometabolic conditions and cancer. Adopting more consistent and less diverse coding would help improve data quality in primary care. Future research is needed following the transfer to the Systematised Nomenclature of Medicine Clinical Terms (SNOMED CT) coding.

Abstract:

We describe a strategy for performing canonical and isothermal-isobaric ensemble hybrid Monte Carlo (HMC) simulations with the widely-used Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) molecular dynamics (MD) software package. The overall workflow for the HMC simulations is handled using an external Python driver script, which invokes LAMMPS’ library interface to perform numerically intensive tasks such as MD integration. We document several rigorous consistency checks that have been used to validate our HMC implementation. We also demonstrate that our approach can be readily extended to implement biased HMC sampling schemes for computing free energies. Codes and input files from the documented examples are available on the web.

Abstract:

Ethnocultural and ethnolinguistic codes have historically shaped and sustained social relationships, guiding collective behavior and actions. One notable example is the blood feud, traditionally governed by canonical acts. In modern societies, there is an ongoing challenge to shift the entrenched concept of "manhood" — from the belief rooted in the canon that "a man avenges blood" to a contemporary ethos asserting that "a man forgives blood feuds." This study investigates the transformative role of Anton Çetta, a distinguished intellectual from Kosovo, who leveraged ethnocultural and ethnolinguistic codes to drive social change. It examines how Çetta’s cultural and intellectual foundations as an author and scholar intersected with his mission-driven work, ultimately establishing him as a symbol of human rights. The central research question guiding this study is: How did Anton Çetta attain the status of the "wise old man," whose authority facilitated the resolution of blood feuds and fostered reconciliation? The paper explores Çetta’s role in the blood feud reconciliation movement in Kosovo, focusing on three core factors that underpinned his success: (i) his leadership qualities, (ii) his strategic deployment of cultural archetypes, and (iii) his effective use of ethnographic speech codes through storytelling. The findings reveal that Çetta’s intellectual impact propelled an emancipatory and civilizing mission by activating deeply embedded archetypes and ethnolinguistic codes within the collective consciousness. His approach redefined traditional behaviors, fostering new social patterns centered on collective dignity. Ultimately, this study aims to draw generalizable insights from Çetta’s work, highlighting how his intellectual and ethnographic strategies transcended the individual and contributed to broader societal transformation.

Abstract:

Retinyl ester, the most abundant form of vitamin A (retinol), is synthesized by the enzyme lecithin:retinol acyltransferase (LRAT). Previously, we cloned a 2.5kb LRAT cDNA from rodent liver which codes for functional LRAT activity. However, Northern blots of tissues probed with the 2.5kb cDNA revealed the presence of a larger transcript of 5kb as well as several smaller transcripts. To elucidate the nature of the large LRAT transcript, a high-molecular-mass adrenal gland cDNA library was screened. Two similar clones of 3962 and 3187nt were identified which appeared to be part of the 3′-untranslated region (UTR) of a 5358nt LRAT mRNA. The 5.3kb cDNA was then amplified from liver by reverse transcriptase PCR (RT-PCR) and demonstrated to encode functional LRAT activity. The 3′-UTR of the 5.3kb cDNA contains several AAUAAA polyadenylation signals. Analysis of the 3′ ends of LRAT mRNA transcripts from liver, intestine and testis showed the usage of both canonical and non-canonical polyadenylation signals. To further analyse the LRAT mRNAs expressed in vivo, Northern blot analysis was performed using four probes spanning sections from the 5′ end to the distal 3′ end of the 5.3kb LRAT cDNA. The results show that the major 5.3kb transcript uses the canonical signal AAUAAA located at nt 5308, and the major short transcript of 1.5kb uses the non-canonical signal AUUAAA located at nt 1330. The 5.3kb LRAT transcript was predominant in the liver of retinoic acid-repleted vitamin A-deficient rats, coincident with increased quantitative expression of LRAT mRNA and enzyme activity. The differential usage of these polyadenylation signals can explain the presence of multiple LRAT mRNA transcripts which are expressed in different tissue-specific patterns.

Abstract. We introduce ClimateMachine, a new open-source atmosphere modeling framework which uses the Julia language and is designed to be scalable on central processing units (CPUs) and graphics processing units (GPUs). ClimateMachine uses a common framework both for coarser-resolution global simulations and for high-resolution, limited-area large-eddy simulations (LESs). Here, we demonstrate the LES configuration of the atmosphere model in canonical benchmark cases and atmospheric flows using a total energy-conserving nodal discontinuous Galerkin (DG) discretization of the governing equations. Resolution dependence, conservation characteristics, and scaling metrics are examined in comparison with existing LES codes. They demonstrate the utility of ClimateMachine as a modeling tool for limited-area LES flow configurations.

Abstract:

Let {Gi:i∈N} be a family of finite Abelian groups. We say that a subgroup G≤∏i∈NGi is order controllable if for every i∈N, there is ni∈N such that for each c∈G, there exists c1∈G satisfying c1|[1,i]=c|[1,i], supp(c1)⊆[1,ni], and order (c1) divides order (c|[1,ni]). In this paper, we investigate the structure of order-controllable group codes. It is proved that if G is an order controllable, shift invariant, group code over a finite abelian group H, then G possesses a finite canonical generating set. Furthermore, our construction also yields that G is algebraically conjugate to a full group shift.

Digital Poetry produces meanings, representing the result of a continuous and profound semiosis between poetic codes and information technologies. The change of the writing regime had a more profound effect on literature, stimulating the creation of more elaborate instant devices that produce cybertexts. In the current Romanian literature is certified the availability to digital experiments and emergence of virtual reality that does not intend to destroy the canonical literature, only to polarize, preferring complex hyperliterate forms, blogstory, cyberpoetry, that transmitting in poetic text a virtual experience.
