Encoding format transformations in contemporary formation

The research dealt with the topic (transformations of coding format in contemporary art) with regard to the path of the contemporary artist and the importance of his connection to his society. The research problem was determined by answering the following question: (What are the hypothetical requirements for the mind to carry out an aesthetic reading of the various art formats?)As for the second chapter, it included the theoretical framework, which contained two sections, the first included (the concept of communicative codes), while the second section included (the diversity of contemporary formation codes), while the third chapter was concerned with research procedures, and the fourth chapter contained the results and conclusions.

Is Moore’s Moral Objectivist Argument Sufficient Against Moral Relativism?

This study aims to expose certain weaknesses in Moore’s moral objectivist argument against moral relativism and subjectivism. It suggests that a moral objectivist argument has to explain moral diversity against moral relativism. Moral relativism is one of the most critical debates in metaethics, and it can be interpreted in two different ways: one as moral realism and the other as moral anti-realism. Moral realism, when reduced to moral objectivism, excludes moral relativism and subjectivism beyond moral realism. I will refer to this interpretation as narrowed moral realism. But moral realism can be extended in an inclusive way such as moral subjectivism and relativism. I will refer to this as extended moral realism. Due to the focus of the study, I will introduce both extended moral realism and narrowed moral realism in the introduction section. Then, I will address G. E. Moore's narrowed moral realism. I will criticize his arguments for their failure to explain the diversity of moral codes. Finally, I suggest that moral subjectivism and moral relativism can be appropriately addressed within extended moral realism. Contrary to Moore's claims, I contend that moral relativism and moral subjectivism would be claims within moral realism. I also evaluate the two main claims from a moral realist perspective. Moral subjectivism claims that moral reality is constructed by an individual’s mental state. Moral relativism argues that social codes of human conduct completely determine moral reality. In the first section of the study, I discussed moral relativism from a Moorean perspective, which asserts that there are self-evident and indefinable truths at the foundation of objective morality. The second section contends that if Moore is correct, however, it necessitates an explanation for why different cultures accept different moral codes. The third section argues the fact that Moore fails to provide any explanation for this. In the conclusion part, I claim that moral relativism and moral subjectivism can be viewed as moral realist theories based on the failure of Moore's arguments.

Student-teacher communication preferences in Taiwanese older learners

ABSTRACT The role of teacher-student communication in enhancing the learning experience of older learners has received limited attention. This sociolinguistic study addresses this gap by examining the perspectives on this issue held by Taiwanese older learners. Survey data from 231 Taiwanese older learners were analyzed using ANOVA and independent-samples t-tests, with the aim of establishing how their age ranges and occupational backgrounds influenced their concordance teacher communication strategies found in existing literature. While teachers were reported to assume that older learners from elite backgrounds preferred more communication accommodation in class, this study’s results indicated that those with no work experience or who identified as farmers demanded greater respect, flexibility, and diversity of language codes. Age was also significantly correlated with learners’ communication preferences, with those aged 76+ requiring more extensive accommodations than their younger counterparts did.

CoAIcoder: Examining the Effectiveness of AI-assisted Human-to-Human Collaboration in Qualitative Analysis

While AI-assisted individual qualitative analysis has been substantially studied, AI-assisted collaborative qualitative analysis (CQA) – a process that involves multiple researchers working together to interpret data—remains relatively unexplored. After identifying CQA practices and design opportunities through formative interviews, we designed and implemented CoAIcoder, a tool leveraging AI to enhance human-to-human collaboration within CQA through four distinct collaboration methods. With a between-subject design, we evaluated CoAIcoder with 32 pairs of CQA-trained participants across common CQA phases under each collaboration method. Our findings suggest that while using a shared AI model as a mediator among coders could improve CQA efficiency and foster agreement more quickly in the early coding stage, it might affect the final code diversity. We also emphasize the need to consider the independence level when using AI to assist human-to-human collaboration in various CQA scenarios. Lastly, we suggest design implications for future AI-assisted CQA systems.

Evolution of the RNA world: From signals to codes

The accumulated material in evolutionary biology, greatly enhanced by the achievements of modern synthetic biology, allows us to envision certain key hypothetical stages of prebiotic (chemical) evolution. This is often understood as the further evolution in the RNA World towards the RNA-protein World. It is a path towards the emergence of translation and the genetic code (I), signaling pathways with signaling molecules (II), and the appearance of RNA-based components of future gene regulatory networks (III). We believe that these evolutionary paths can be constructively viewed from the perspective of the concept of biological codes (Barbieri, 2003). Crucial evolutionary events in these directions would involve the emergence of RNA-based adaptors. Such adaptors connect two families of functionally and chemically distinct molecules into one functional entity.The emergence of primitive translation processes is undoubtedly the major milestone in the evolutionary path towards modern life. The key aspect here is the appearance of adaptors between amino acids and their cognate triplet codons. The initial steps are believed to involve the emergence of proto-transfer RNAs capable of self-aminoacylation.The second significant evolutionary breakthrough is the development of biochemical regulatory networks based on signaling molecules of the RNA World (ribonucleotides and their derivatives), as well as receptors and effectors (riboswitches) for these messengers. Some authors refer to this as the “lost language of the RNA World."The third evolutionary step is the emergence of signal sequences for ribozymes on the molecules of their RNA targets. This level of regulation in the RNA World is comparable to the gene regulatory networks of modern organisms. We believe that the signal sequences on target molecules have been rediscovered and developed by evolution into the gene regulatory networks of modern cells.In conclusion, the immense diversity of modern biological codes, in some of its key characteristics, can be traced back to the achievements of prebiotic evolution.

Sound-absorbing aerated concrete based on China fly ash

Introduction. The development of aerated concrete with a high content of open pores, using polymineral binders with reduced cement content and significant utilization of local technogenic resources (in particular, enriched waste from thermal power plants) is relevant for the modern construction industry. To systematize modern methods for studying the characteristics of sound insulation and sound protection of buildings, it is necessary to take into account the diversity of international building codes. The aim of the work is to develop a scientifically based technological solution that provides effective aerated concrete based on fly ash from China with improved sound-absorbing characteristics.Main part. In this paper, a methodological basis, which provides for the comprehensive use of fundamental approaches in building materials science, was used. Integrated design to develop composite materials of a given quality at the nano-, micro- and macrolevels was used. The physical and mechanical properties of raw materials and the required characteristics of the developed materials using physicochemical methods of analysis, including laser granulometry, X-ray phase analysis, scanning electron microscopy, thermal methods, etc were studied. The experimental studies in the laboratories of V.G. Shukhov BSTU, as well as Chinese universities were carried out.Conclusions. In this work, scientific approaches for the design and synthesis of aerated concrete with improved acoustic characteristics in various regions of the country, taking into account local raw materials were formulated. Further research can be aimed at expanding the range of lightweight materials for building envelopes in order to ensure a safe human environment. This can be achieved by synthesizing multicomponent composite binders that affect the formation of nano-, micro- and macrostructures of materials.

On Symmetric Multilevel Diversity Coding System With Linear Computations

In a conventional Symmetric Multilevel Diversity Coding System (SMDCS), sources of varying importance are encoded by multiple encoders and a level- <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> decoder, if given access to any <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> encoders, can decode the first <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> most important sources. In practical large-scale applications like Non-terrestrial Networks, sinks (e.g., land earth stations) may be only interested in some functions of the sources (e.g., orbiting satellites) rather than the sources themselves. This paper introduces linear network function computations into the SMDCS, where a level- <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> decoder requests a linear function of the first <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> sources. The coding rate region of the 3-encoder (i.e., 3-level) SMDCS with linear computations (SMDCS-LC) was obtained. It is shown that when the coefficient vectors are dependent, coding between sources may help in reducing the information under transmission by encoders. However, when they are independent, superposition (i.e., sources-separated) coding is optimal. Furthermore, the minimum sum rate of the generic <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</i> -level SMDCS-LC is obtained. This can find applications like federated learning aggregation in Non-Terrestrial Networks.

Mixed Pseudo-orthogonal Frequency Coding for SAW RFID Tags

A mixed pseudo-orthogonal frequency coding (Mixed-POFC) structure is proposed as a new spreadspectrum technique in this paper, which employs frequency and time diversity to enhance tag properties and balances the spectrum utilization and code diversity. The coding method of SAW RFID tags in this paper uses Mixed-POFC with multi-track chip arrangements. The cross-correlation and auto correlation of Mixed-POFC and POFC are calculated to demonstrate the reduced overlap between the adjacent center frequencies with the Mixed-POFC method. The center frequency of the IDT and Bragg reflectors is calculated by a coupling of modes (COM) module. The combination of the calculation results of the Bragg reflectors shows that compared with a 7-chip POFC, the coding number of a 7-chip Mixed-POFC is increased from 120 to 144 with the same fractional bandwidth of 12%. To demonstrate the validity of Mixed-POFC, finite element analysis (FEA) technology is used to analyze the frequency characteristics of Mixed-POFC chips. The maximum error between designed frequencies and simulation frequencies is only 1.7%, which verifies that the Mixed-POFC method is feasible.

Gene Content and Coding Diversity of the Growth Hormone Loci of Apes.

The growth hormone (GH) locus has experienced a dramatic evolution in primates, becoming multigenic and diverse in anthropoids. Despite sequence information from a vast number of primate species, it has remained unclear how the multigene family was favored. We compared the structure and composition of apes' GH loci as a prerequisite to understanding their origin and possible evolutionary role. These thorough analyses of the GH loci of the chimpanzee, gorilla, and orangutan were done by resorting to previously sequenced bacterial artificial chromosomes (BACs) harboring them, as well as to their respective genome projects data available in GenBank. The GH loci of modern man, Neanderthal, gibbon, and wild boar were retrieved from GenBank. Coding regions, regulatory elements, and repetitive sequences were identified and compared among species. The GH loci of all the analyzed species are flanked by the genes CD79B (5') and ICAM-1 (3'). In man, Neanderthal, and chimpanzee, the loci were integrated by five almost indistinguishable genes; however, in the former two, they rendered three different hormones, and in the latter, four different proteins were derived. Gorilla exhibited six genes, gibbon seven, and orangutan four. The sequences of the proximal promoters, enhancers, P-elements, and a locus control region (LCR) were highly conserved. The locus evolution might have implicated duplications of the ancestral pituitary gene (GH-N) and subsequent diversification of the copies, leading to the placental single GH-V gene and the multiple CSH genes.

The splenic T cell receptor repertoire during an immune response against a complex antigen: Expanding private clones accumulate in the high and low copy number region.

Large cellular antigens comprise a variety of different epitopes leading to a T cell response of extreme diversity. Therefore, tracking such a response by next generation sequencing of the T cell receptor (TCR) in order to identify common TCR properties among the expanding T cells represents an enormous challenge. In the present study we adapted a set of established indices to elucidate alterations in the TCR repertoire regarding sequence similarities between TCRs including VJ segment usage and diversity of nucleotide coding of a single TCR. We combined the usage of these indices with a new systematic splitting strategy regarding the copy number of the extracted clones to divide the repertoire into multiple fractions for separate analysis. We implemented this new analytic approach using the splenic TCR repertoire following immunization with sheep red blood cells (SRBC) in mice. As expected, early after immunization presumably antigen-specific clones accumulated in high copy number fractions, but at later time points similar accumulation of specific clones occurred within the repertoire fractions of lowest copy number. For both repertoire regions immunized animals could reliably be distinguished from control in a classification approach, demonstrating the robustness of the two effects at the individual level. The direction in which the indices shifted after immunization revealed that for both the early and the late effect alterations in repertoire parameters were caused by antigen-specific private clones displacing non-specific public clones. Taken together, tracking antigen-specific clones by their displacement of average TCR repertoire characteristics in standardized repertoire fractions ensures that our analytical approach is fairly independent from the antigen in question and thus allows the in-depth characterization of a variety of immune responses.

Diversity of spatiotemporal coding reveals specialized visual processing streams in the mouse cortex

The cerebral cortex contains diverse neural representations of the visual scene, each enabling distinct visual and spatial abilities. However, the extent to which representations are distributed or segregated across cortical areas remains poorly understood. By determining the spatial and temporal responses of >30,000 layer 2/3 pyramidal neurons, we characterize the functional organization of parallel visual streams across eight areas of the mouse cortex. While dorsal and ventral areas form complementary representations of spatiotemporal frequency, motion speed, and spatial patterns, the anterior and posterior dorsal areas show distinct specializations for fast and slow oriented contrasts. At the cellular level, while diverse spatiotemporal tuning lies along a continuum, oriented and non-oriented spatial patterns are encoded by distinct tuning types. The identified tuning types are present across dorsal and ventral streams. The data underscore the highly specific and highly distributed nature of visual cortical representations, which drives specialization of cortical areas and streams.

Metrics in outpatient stewardship: Is more always better?

Background: Emerging evidence supports the use of billing data to identify stewardship targets in primary care. Standardizing an approach to antibiotic prescribing rate (APR) calculations could facilitate external benchmarking. Methods: Using methodology and an ICD-10 dictionary validated in urgent care clinics,1 we created an expanded ICD-10 dictionary to incorporate additional ICD-10 codes from primary care associated with antibiotic prescriptions (Fig. 1). We then compared antibiotic prescribing rates using the urgent care and expanded dictionaries. We included all primary care visits from 2019 to 2020 and extracted ICD-10 codes and antibiotic order data. Using the urgent care and expanded ICD-10 dictionary, we classified each encounter by prescribing tier based on whether antibiotics are almost always (tier 1), sometimes (tier 2), or almost never (tier 3) indicated. For encounters with ICD-10s in multiple tiers, we chose the lowest tier. For multiple ICD-10 codes within the same tier, we chose the first extracted ICD-10 code. We calculated antibiotic prescribing rates as the proportion of encounters associated with ≥ 1 antibacterial prescription. This quality improvement project was deemed non–human subjects research by the Stanford Panel on Human Subjects in Medical Research. Results: The urgent care dictionary has 1,400 ICD-10 codes. We added 1,439 ICD-10 codes derived from primary care encounters to create the expanded ICD-10 dictionary (8.5% tier 1, 9.1% tier 2, and 82.4% tier 3) (Fig. 1). We identified 177,531 encounters; 74% had ≥ 2 associated ICD-10 codes (Fig. 2). In total, 147,085 encounters (82.9%) were classified into a tier using the urgent care dictionary. An additional 22,039 encounters were classified with the expanded dictionary (Table 1). Most added encounters were tier 3 with low 0.7% APR (Tables 1 and 3). In total, 41,473 (28.2%) encounters were classified differently depending on the ICD-10 dictionary used, most commonly changing from tier 3 to tier 2 without an increase in overall tier 2 antibiotic prescribing rate (Tables 2 and 3). Overall antibiotic prescribing rates were similar when using either the urgent care or expanded ICD-10 dictionary (Table 2). Conclusions: The expanded ICD-10 dictionary allowed for classification of more encounters in primary care; however, it did not meaningfully change antibiotic prescribing rates. Antibiotic prescribing rates were likely diluted by classifying more encounters without identifying an associated increase in antibiotic prescribing. A more sophisticated classification system may help to accommodate the diversity and volume of ICD-10 codes used in primary care.1. Stenehjem E, et al.

Soft gender diversity regulations for boards of directors: the moderating role of firm ownership and control structure

ABSTRACT Women are significantly underrepresented worldwide on corporate boards of directors, leading to board gender diversity regulations. Drawing from agency and socioemotional wealth theories, we investigate the moderating effect of ownership structure, shareholder identity and shareholder control on how gender diversity codes and soft quotas influence women’s representation on boards. We analyse our sample of Spanish Stock Exchange firms using panel data Tobit models. The results show that a single large shareholder enhances the positive impact of regulations, while multiple blockholders diminish it. Blockholder identity also matters: family control of board seats and families as the sole large shareholders reduce the positive impact of board gender diversity regulations on women’s board representation. In family firms, the balance of power between family and non-family shareholders also affects the impact of regulations. Our findings highlight the need to consider firm ownership and control structure when developing regulations to promote board gender diversity.

The failure of the ‘Housing Diversity Code’ to deliver housing diversity

ABSTRACT This article explores the policy failure of the NSW ‘Low Rise Housing Diversity Code’ (implemented through State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (Codes SEPP)). The Code came into full effect (across all NSW LGAs) on the 1st of July 2020 following a number of deferral periods since its formal adoption in 2018. The Code was intended to address Sydney's ‘missing middle’, notably medium density housing to address affordability and the relative imbalance in available housing typologies between polarised market choices; the detached suburban house on a remote (greenfields) lot, and the apartment in a high density metropolitan centre. The policy ultimately failed to deliver the intended diversity it had seemingly promised. This article explores technical, legislative, political and economic factors contributing to the Code's limited application, as well as actions that further curtailed housing diversity, counter to the Code's intent.

Maternal–Fetal Microchimerism and Genetic Origins: Some Socio-legal Implications

What are the implications of microchimerism in sociocultural and ethico-legal contexts, particularly as they relate to the destabilization of genetic origins? Conventional biomedicine and related law have been reluctant to acknowledge microchimerism—the existence of unassimilated traces of genetic material that result in some cells in the body coding differently from the dominant DNA—despite it becoming increasingly evident that microchimerism is ubiquitous in the human population. One exception is maternal–fetal microchimerism which has long been recognized, albeit with little consideration of the nonmedical implications. Most immediate issues concern the ongoing biomedical debate around whether microchimerism is beneficial in terms of enhancing the body’s range of immunological responses, harmful in provoking autoimmune diseases, or simply neutral with respect to subsequent health. That controversy remains unresolved, but whichever way it develops, I want to extend consideration by insisting that changing biological concerns cannot be separated from sociocultural and ethico-legal effects. Once the diversity of DNA coding in a singular body has been established, relations of kinship, the identification of legal parenthood, and the operation of surrogacy laws are of direct interest. The overriding problematic asks whether our ethical and legal apparatus is able to address such newly emerging questions.

Space–Time Codes From Sum-Rank Codes

Just as rank-metric or Gabidulin codes may be used to construct rate–diversity tradeoff optimal space–time codes, a recently introduced generalization for the sum-rank metric—linearized Reed–Solomon codes—accomplishes the same in the case of multiple fading blocks. In this paper, we provide the first explicit construction of minimal delay rate–diversity optimal multiblock space–time codes as an application of linearized Reed–Solomon codes. We also provide sequential decoders for these codes and, more generally, space–time codes constructed from finite field codes. Simulation results show that the proposed codes can outperform full diversity codes based on cyclic division algebras at low SNRs as well as utilize significantly smaller constellations.

Field Evaluation of Transmit Diversity Code Filter Sets in ATSC 3.0 Single Frequency Networks

Advanced Television Systems Committee (ATSC) 3.0, a recently developed terrestrial broadcasting standard, supports a Single Frequency Network (SFN), which extends service coverage and enhances received field strength without additional frequency resources. In SFN, multiple transmitters emit identical ATSC 3.0 broadcasting signals, which may cause constructive or destructive interference on a receiver side. The worst situation occurs when two signals from different transmitters are received with the opposite phase and similar power within a sample time, causing the cancellation of the received signal. In order to prevent such signal cancellation, ATSC 3.0 adopted transmitter diversity code filter sets (TDCFS), which is a frequency domain pre-distortion scheme to minimize cross-correlation among multiple transmitter signals in SFN. This paper sets up an ATSC 3.0 SFN consisting of two transmitter sites, transmitting high definition (HD) for mobile service and 4K ultra high definition (UHD) for fixed service. Layered division multiplexing (LDM) and time division multiplexing (TDM) are used to simulcast the two services with different robustness in the same radio frequency (RF) channel. Then, performance is evaluated using a threshold of visibility (ToV) and a successful reception rate. The time and frequency channel responses are changed at the same reception area when TDCFS is applied so the results show that reception performance is improved in the worst situation in SFN.

A computational screen for alternative genetic codes in over 250,000 genomes.

The genetic code has been proposed to be a 'frozen accident,' but the discovery of alternative genetic codes over the past four decades has shown that it can evolve to some degree. Since most examples were found anecdotally, it is difficult to draw general conclusions about the evolutionary trajectories of codon reassignment and why some codons are affected more frequently. To fill in the diversity of genetic codes, we developed Codetta, a computational method to predict the amino acid decoding of each codon from nucleotide sequence data. We surveyed the genetic code usage of over 250,000 bacterial and archaeal genome sequences in GenBank and discovered five new reassignments of arginine codons (AGG, CGA, and CGG), representing the first sense codon changes in bacteria. In a clade of uncultivated Bacilli, the reassignment of AGG to become the dominant methionine codon likely evolved by a change in the amino acid charging of an arginine tRNA. The reassignments of CGA and/or CGG were found in genomes with low GC content, an evolutionary force that likely helped drive these codons to low frequency and enable their reassignment.
