Deriving Flow Velocity and Initial Concentration From Liesegang‐Like Patterns

AbstractZebra rocks, characterized by their striking reddish‐brown stripes, rods, and spots of hematite (Fe‐oxide), showcase complex self‐organized patterns formed under far‐from‐equilibrium conditions. Despite their ease of recognition, the underlying mechanisms of pattern‐forming processes remain elusive. We introduce a novel advection‐dominated phase‐field model that effectively replicates the Liesegang‐like patterns observed in Zebra rocks. This numerical model leverages the concept of phase separation, a well‐established principle governing Liesegang phenomena in a two‐dimensional setting. Our findings reveal that initial solute concentration and fluid flow velocity are critical determinants in pattern morphologies. We quantitatively explain the spacing and width of a specific Liesegang‐like pattern category. Furthermore, the model demonstrates that vanishingly low initial concentrations promote the formation of oblique patterns, with inclination angles influenced by rock heterogeneity. Additionally, we establish a quantitative relationship between band thickness and geological parameters for orthogonal bands. This enables the characterization of critical geological parameters based solely on static patterns observed in Zebra rocks, providing valuable insights into their formation environments. The diverse patterns in Zebra rocks share similarities with morphologies observed on early Earth and Mars, such as banded iron formations and hematite spherules. Our model, therefore, offers a plausible explanation for the formation mechanisms of these patterns and presents a powerful tool for deciphering the geochemical environments of their origin.

The Impact and Response of Android Mobile Application Utilization of Health Consultations by Pregnant Women in Indonesia

The targets pertaining to Sustainable Development Goals for the period spanning from 2020 to 2021 have been revised downwards, notwithstanding a notable surge of 25 percent in the use of mobile-based health applications. Hence, the objective of this study is to create a mobile application called "Nutribid" that provides online counselling services for reproductive health and nutrition, specifically designed for Android devices. The participants of this research were 56 pregnant women residing in Purwadana Village, Indonesia, who utilised mobile devices equipped with the Android operating system. The findings indicate that a significant majority of the participants, above 90%, expressed agreement with the ease of identification, download, and use of the Nutribid application. Nevertheless, it is worth noting that a significant proportion, specifically 60.7% of the participants, expressed their dissatisfaction with the colour scheme employed in the application. Conversely, an overwhelming majority of the respondents concurred that the Nutribid application menu possesses commendable attributes such as ease of recognition, discoverability, legibility, and usability. The utilisation of mobile health applications has witnessed significant growth, yet, its integration into Indonesian society encounters many challenges attributed to the limited internet network infrastructure.

Three-dimensional visualization improves the endoscopic diagnosis of superficial gastric neoplasia

BackgroundThree-dimensional (3D) technology has been used in many fields, including flexible endoscopy. We evaluated the usefulness of 3D visualization for endoscopically diagnosing superficial gastric neoplasia.MethodsTwelve participants (4 novices, 4 trainees and 4 experts) evaluated two-dimensional (2D) and 3D endoscopic still images of 28 gastric neoplasias, obtained before ESD with white-light imaging (WLI) and narrow-band imaging (NBI). Assessments of the delineation accuracy of tumor extent and tumor morphology under 2D and 3D visualization were based on the histopathological diagnosis of ESD specimens. Participants answered visual analog scale (VAS) questionnaires (0–10, worst to best) concerning the (a) ease of recognition of lesion morphology, (b) lesion extent and (c) comprehensive endoscopic cognition under 2D and 3D visualization. The endpoints were the accuracy of tumor extent and morphology type and the degree of confidence in assessing (a)–(c).ResultsThe delineation accuracy of lesion extent [mean (95% confidence interval)] with WLI under 3D visualization [60.2% (56.1–64.3%)] was significantly higher than that under 2D visualization [52.3% (48.2–56.4%)] (P < 0.001). The accuracy with NBI under 3D visualization [70.3% (66.8–73.7%)] was also significantly higher than that under 2D visualization [64.2% (60.7–67.4%)] (P < 0.001). The accuracy of the morphology type with NBI under 3D visualization was significantly higher than that under 2D visualization (P = 0.004). The VAS for all aspects of endoscopic recognition under 3D visualization was significantly better than that under 2D visualization (P < 0.01).ConclusionsThree-dimensional visualization can enhance the diagnostic quality for superficial gastric tumors.

Russian-language adaptation of the international nomenclature of International Consensus on Antinuclear Antibody (ANA) Patterns (ICAP)

Antinuclear antibodies (ANAs) represent a spectrum of autoantibodies targeted for various nuclear and cytoplasmic components of the cells. Indirect immunofluorescence assay (IIF) is the main detection method for “antinuclear factor”. A positive ANA test is usually reported as a titer and a pattern of fluorescence. The ANA patterns refers to the distribution of staining produced by antibodies that react with antigens located in nucleus and cytoplasm of HEp-2 cells. To standardize nomenclature and descriptions of the various fluorescence patterns of antinuclear factor (ANF), the Initiative of the International Consensus on ANA Patterns (ICAP) group was developed in 2014. The aim of ICAP is to promote consensus regarding nomenclature of ANA patterns, a microphotograph database, as well as classification depending on the employee skills. Information on the main characteristics, as well as specific clinical associations of the patterns is available at www.ANApatterns.org. In ANA classification trees, the patterns are indicated by the #AC (anticell pattern) alphanumeric code, being divided into nuclear, cytoplasmic and mitotic groups. Depending on the clinical significance and/or ease of recognition, this nomenclature focuses on the differences between the patterns described by specialists at competent and expert levels. Of the nuclear types, the most significant are homogeneous, speckled, dense fine-speckled, centromere, nucleolar, nuclear dots. The cytoplasmic types may be discerned into fibrillar, speckled, mitochondrial, Golgi, rods and rings. On leaders, behalf of the ICAP translation team is headed by the Full Member of Russian Academy of Sciences, Professor A.A. Totolian, under the auspices of the Russian Research Society of Immunologists. In this article, we present the Russianlanguage adaptation of the ICAP nomenclature, in order to ensure unification and standardization of ANA detection results in the patients with autoimmune diseases.

Implementation and Evaluation of a Standardized Non-Vitamin K Oral Anticoagulant (NOAC) Patient Safety Alert Card Across the Northern Region of England.

Many patients are prescribed anticoagulants. Newer non–vitamin K oral anticoagulants, NOACs, were launched in 2008 and are increasingly commonly used. However, they may still be unfamiliar to patients and health care professionals. It is mandated by the National Patient Safety Agency and European Society of Cardiology to provide written safety information for patients receiving anticoagulants. We developed a standard patient alert card with the support of the North of England Strategic Clinical network (NESCN) to clearly provide key safety information for patients and health care professionals. This is the only card in the United Kingdom that is used over such a wide geographical area. We recognized that this would avoid duplication of work devising a similar card across all the sites in primary and secondary care. Given that staff and patients commonly move about the region it would also lead to better ease of recognition. The NESCN card was developed with input from all the key stakeholders, including cardiology, stroke, hematology, acute medicine, primary care, and patient groups. It was launched in 2015 across the Northern region, which includes over 3 million people. It was distributed to general practitioners (GPs), primary and secondary care pharmacists. Electronic and face-to-face education was carried out alongside to pharmacists, GPs, and hospital physicians. We gathered patient and clinical staff feedback regarding the card and found the alert card was widely embedded within practice across the region and patient feedback was good. The evaluation shows a simple and inexpensive intervention delivered with no formal funding can address this patient safety concern. We have engaged with Clinical Commissioning Groups and secondary care trusts in the region to ensure the legacy of the project. In response to requests from other regions and organizations, the card has been widely shared and implemented across many areas of the United Kingdom.

The Aesthetic Preference for Nature Sounds Depends on Sound Object Recognition.

People across the world seek out beautiful sounds in nature, such as a babbling brook or a nightingale song, for positive human experiences. However, it is unclear whether this positive aesthetic response is driven by a preference for the perceptual features typical of nature sounds versus a higher-order association of nature with beauty. To test these hypotheses, participants provided aesthetic judgments for nature and urban soundscapes that varied on ease of recognition. Results demonstrated that the aesthetic preference for nature soundscapes was eliminated for the sounds hardest to recognize, and moreover the relationship between aesthetic ratings and several measured acoustic features significantly changed as a function of recognition. In a follow-up experiment, requiring participants to classify these difficult-to-identify sounds into nature or urban categories resulted in a robust preference for nature sounds and a relationship between aesthetic ratings and our measured acoustic features that was more typical of easy-to-identify sounds. This pattern of results was replicated with computer-generated artificial noises, which acoustically shared properties with the nature and urban soundscapes but by definition did not come from these environments. Taken together, these results support the conclusion that the recognition of a sound as either natural or urban dynamically organizes the relationship between aesthetic preference and perceptual features and that these preferences are not inherent to the acoustic features. Implications for nature's role in cognitive and affective restoration are discussed.

Workplace Religious Displays and Perceptions of Organization Attractiveness

Workplace religious expression has become an intensely debated topic across news outlets and social media. However research on what constitutes acceptable vs unacceptable workplace religious display is sparse. At a time when EEOC claims involving religion are on the rise there is a clear need for study in this area. In this study participants in two samples read 27 scenarios where an interviewer engaged in a Christian religious display during a job interview. We used Christian religious displays for their ease of recognition in an American sample. Participants rated each workplace religious display in terms of likelihood of occurrence and organization attractiveness. In both samples organization attractiveness ratings were more negative than expected in a predominantly Christian sample signifying that while individuals may value their ability to express their religion they may not appreciate such displays from those who represent an organization. Verbal and physical religious displays received more negative ratings compared to scenarios that spoke to shared experiences such as displaying pictures of one’s children in a religious ceremony. Application in organizations and HR implications are discussed.

Studying Cat (Felis catus) Diabetes: Beware of the Acromegalic Imposter.

Naturally occurring diabetes mellitus (DM) is common in domestic cats (Felis catus). It has been proposed as a model for human Type 2 DM given many shared features. Small case studies demonstrate feline DM also occurs as a result of insulin resistance due to a somatotrophinoma. The current study estimates the prevalence of hypersomatotropism or acromegaly in the largest cohort of diabetic cats to date, evaluates clinical presentation and ease of recognition. Diabetic cats were screened for hypersomatotropism using serum total insulin-like growth factor-1 (IGF-1; radioimmunoassay), followed by further evaluation of a subset of cases with suggestive IGF-1 (>1000 ng/ml) through pituitary imaging and/ or histopathology. Clinicians indicated pre-test suspicion for hypersomatotropism. In total 1221 diabetic cats were screened; 319 (26.1%) demonstrated a serum IGF-1>1000 ng/ml (95% confidence interval: 23.6–28.6%). Of these cats a subset of 63 (20%) underwent pituitary imaging and 56/63 (89%) had a pituitary tumour on computed tomography; an additional three on magnetic resonance imaging and one on necropsy. These data suggest a positive predictive value of serum IGF-1 for hypersomatotropism of 95% (95% confidence interval: 90–100%), thus suggesting the overall hypersomatotropism prevalence among UK diabetic cats to be 24.8% (95% confidence interval: 21.2–28.6%). Only 24% of clinicians indicated a strong pre-test suspicion; most hypersomatotropism cats did not display typical phenotypical acromegaly signs. The current data suggest hypersomatotropism screening should be considered when studying diabetic cats and opportunities exist for comparative acromegaly research, especially in light of the many detected communalities with the human disease.

Augmentative and Alternative Communication System (AAC) for Social Inclusion of People With Complex Communication Needs in the Industry

Inclusion of people with special needs in the labor market has been increasing in some regions of Brazil as a result of the Articles 6 and 7 of the Constitution of the Federal Republic of Brazil and the Quota Law (No. 8.213/91, Art. 93) which entitle people with disabilities to work in order to improve their social condition. To support persons with complex communication needs in the workplace, 40 graphic symbols termed “symbols of industrial expressions” were developed within the framework of the COMMUNIS package. The symbols were developed for a company of the food sector in the Metropolitan Region of Curitiba, Brazil. Individual interviews were held with the human resources professionals, as well as with employees with complex communication needs in order to identify problems, assess requirements, and generate a list of specific symbols to develop. The symbols were then validated with regard to their ease of recognition. Only five symbols needed revision. The results suggest that it is possible to develop a set of symbols for the workplace that are judged to be iconic by human resources professionals and employees with complex communication needs.

Splendid Hybrids: The Effects of a Tiger Beetle Hybrid Zone on Apparent Species Diversity

Nonexpert citizen groups are being used to monitor species to track ecosystem changes; however, challenges remain for proper identification, especially among diverse groups such as beetles. Tiger beetles,Cicindelaspp., have been used for biological diversity monitoring because of their diversity and the ease of recognition. The finding of an apparent hybrid zone amongCicindela denverensisCasey,Cicindela limbalisKlug, andCicindela splendidaHentz in central Nebraska prompted a detailed study of the biogeography of this species group within Nebraska, a test of characteristics that could be used by citizen scientists, and limited breeding experiments. This study suggests that whileC. denverensisappears to hybridize with bothC. limbalisandC. splendidawithin the hybrid zone, all three species maintain their integrity across most of their ranges, largely occupy unique geographic regions, and at leastC. denverensisandC. splendidacooccur in many areas with no evidence of hybridization. Evidence of hybridization betweenC. limbalisandC. splendidawas found at only two sites. Furthermore, breeding experiments with virginC. splendidaandC. denverensisshowed that they are capable of producing hybrid larvae in the laboratory. The presence of morphological intergrades serves as a cautionary note when using biological indicator species.

Irish trade unions under social partnership: a Faustian bargain?

Since 1987 trade unions have been a key party to social partnership agreements in Ireland. Theoretical and empirical studies of corporatism point to positive outcomes for trade unions such as an increase in union density, ease of recognition, and increased employer support. However, apart from a modest increase in union membership numbers, none of these outcomes were realised. Union density levels have decreased significantly, union recognition is more problematic than ever, and employer opposition appears to have increased in scope and intensity. Decline in union density questions the capacity of unions to remain pivotal actors in the future. During the period of partnership union density in the private sector more than halved. It remains the paradox of partnership.

A Study on the Textuality Represented in Modern Fashion Photographs

Today, as individuals show their social identities and reflect their being as the members of society with a culture, an art style and communication function are stood out in fashion photographs. Accordingly, the meanings of images into text are expanded in its interpretative width through the acceptor's various terms. This researcher looked into four theories of both positions on the textuality of language and image, and considered the point of discussion on image of each theory through modern fashion photographs. First, the theory which divides language and image as auditory and visual recognitions in the textuality of language and image is limited from the view it focuses on only one side without considering the ambivalent elements of each field. For the textuality in modern fashion photographs, the observer attempts to turn it into text to give meaning to it as the recognition through five senses conforming to the acceptor's condition. Second, the theory dividing language and image into the text of time properties and spacial properties has limitation in the text, for acceptor's experience of the object appears as the structured form in time and space rather than being defined as two things like time and space. Third, the theory classifying the language and image text into conventional taste and natural taste has limitation from the view that image text is hardly an object of consistent classification in ease of recognition by the code accepted in society. Thus, this can't be fundamental approach for the understanding of the text of decoding trend represented in modern fashion photographs. Fourth, accordingly, this researcher focussed on contextual and arbitrary text of fashion photographs through the theory of Nelson Goodman which discusses image text through the differences in textuality. Basic mechanism of perceiving and recognizing and distinguish image is closely related to habit and custom like language. So, each acceptor perceives the image as a text through arbitrary interpretation obtained by individual, empirical, historical, and educational viewpoints. The textuality of modern fashion photographs aims to widen the range of diverse knowledge and understanding, transcending the regulations of simple function of existing fashion photographs. Consequently, this researcher puts forward the opinion of consistent and diverse follow-up studies on instilling meaning into fashion photographs for the understanding de-regulatory and de-constructive through various senses by avoiding only one sense-dependent fixed and regulatory properties of it.

Intuition beyond recognition: when less familiar events are liked more.

In a laboratory experiment, we compare the relative impact of two possible determinants of intuitive evaluative judgments: ease of recognition and total value of prior encounters with a target. Participants encode daily return values of shares on the stock market while watching videotaped ads on the computer screen. This dual-task procedure ensures that participants subsequently lack relevant event memories and thus have to rely on their intuition when evaluating the targets. In the presentation, the share appearing least frequently produced the highest sum of returns. In contrast, the share appearing most frequently produced the lowest sum of returns. Evaluative judgments reveal a preference for the share with the highest sum of returns, although, as evident from recognition latencies, it was the one that was more difficult to recognize. The results provide evidence for the value-account model of implicit attitude formation (Betsch, Plessner, Schwieren, & Gütig, 2001), which predicts that intuitive evaluative judgments reflect the total value of prior encounters.

Foodborne Disease Outbreaks, 5-Year Summary, 1983–1987

This report summarizes data from foodborne disease outbreaks reported to CDC from 1983 through 1987. With a few exceptions, an outbreak is defined as an incident in which two or more persons experience a similar illness and food is implicated. During this period, 2,397 outbreaks of foodborne disease were reported, representing 91,678 cases. Among outbreaks in which the etiology was determined, bacterial pathogens caused the largest number of outbreaks (66%) and cases (92%). Chemical agents caused 26% of outbreaks and 2% of cases. Parasites caused 4% of outbreaks and <1% of cases, and viruses caused 5% of outbreaks and 5% of cases. The discrepancies between the number of outbreaks and the number of cases attributed to each etiologic agent emphasizes the importance of evaluating both numbers before drawing conclusions. The etiologic agent was not determined in 62% of outbreaks, reflecting the need for improved investigative skills. The number of outbreaks reported by this surveillance system is only a small fraction of the true number that occur. The likelihood of an outbreak's being reported depends on many factors, such as ease of recognition and ease of laboratory confirmation. Sporadic foodborne illness is far more common and is not included in this report

A computerized system for rapid retrieval and compilation of critical or interesting patient data

The timely availability and presentation of critical and interesting patient data is essential to ensure quality patient care as well as ease of recognition and, secondarily, to provide material for teaching and research. The ability to accomplish these goals expeditiously in a complex and busy clinical laboratory may be difficult to acquire. An on-line, computerized system has been developed which automatically searches each patient record for up to 600 different laboratory tests, compares each result against individually established limits, and then formats pertinent test results for maximum discrimination. The report format also includes patient and specimen collection data, diagnosis, attending physician's name, and other desired associated test results. An additional feature of the system is that selected critical or interesting results for each laboratory division may be displayed on video display terminals located throughout the laboratory and at nursing stations. The system was written using the FORTRAN programming language and runs on a Control Data Cyber 18 computer.

Ergonomics standards and research for cars

This paper reviews some ergonomics tools available for car design, also an outline of how ergonomics principles and specific research have provided relevant information for designers. Further indications are given of the use of such ergonomics data in the development of in-house and ISO standards, as well as their subsequent influence on regulations. The two main areas discussed are symbols and electronic instrumentation. By the 1960s symbols were becoming a popular way of identifying controls and displays, especially for an international product. A simple experiment was conducted to relate the size of symbol to its ease of recognition. This yielded data which were used to establish an internal standard. The form of the symbols is perhaps more significant than the size. A number of experimental studies have been made of the ease with which drivers can relate symbols to the function and the ease with which these can be learnt. As a result, better symbols have been selected and in some cases the need for redesign shown clearly. This process has played a very important part in the formation of International Standards and in the harmonisation of regulations in many parts of the world. The advent of low cost electronics and electro-optical devices is beginning to influence car instrumentation. A substantial series of experiments has been conducted, concentrating on the format of the speedometer. This has shown clear advantages for digital instruments, although it also points to a few warnings. Various aids to the ergonomics design of electronic instruments are outlined.

Ease of identifying words degraded by visual noise.

A technique is described for investigating word recognition involving the superimposition of 'noise' on the visual target word. For this task a word is printed in the form of letters made up of separate elements; noise consists of additional elements which serve to reduce the ease whereby the words may be recognized, and a threshold-like measure can be obtained in terms of the amount of noise. A word frequency effect was obtained for the noise task, and for words presented tachistoscopically but in conventional typography. For the tachistoscope task, however, the frequency effect depended on the method of presentation. A second study showed no effect of inspection interval on performance on the noise task. A word-frequency effect was also found in a third experiment with tachistoscopic exposure of the noise task stimuli in undegraded form. The question of whether common processes are drawn on by tasks entailing different ways of varying ease of recognition is addressed, and the suitability of different tasks for word recognition research is discussed.

Perception of structure in short melodic sequences.

Three experiments studied the perception of tone sequences having various degrees of musical structure. Ratings of perceived structure and ease of recognition in transposition were both influenced by harmonic progression (as defined by music theory), the contour (directional changes in pitch), and the excursion or repetition pattern within the sequence. The relation between the original and transposed sequence also affected ease of recognition in accordance with the number of tones shared between the two sequences. The results are described in terms of the abstraction and analysis of levels of pitch relations, an analysis conducted even by musically untrained listeners. The conceptual framework emphasizes the application of musical rules as an illustration of rules governing auditory sequences in general.

Children's recognition memory for their drawings.

One hundred preschool boys and girls (2 1/2 and 5 1/2 year old) were asked to recognize four drawings they had made a week earlier. The child's drawing was presented with three foils which varied along the following dimensions: detail, size, and perspective. Chance performance was .25 correct; the group's performance of .34 correct was significantly different from chance (p < .0001); the oldest children's performance was .39 correct (p < .0001). These performances are impressive because of the slight variation between the target and foil drawings. The amount of differentiation in the children's drawings may be a factor in the ease of recognition.
