The Effect of Spatial Production in Hair Salons on Customer’s Revisit Intention and Word-of-Mouth Intention

The purpose of this study is to provide more practical basic data for hair salon marketing strategies by examining the effect of spatial production in hair salons on customer’s revisit intention and word-of-mouth intention. As a result, it was found that only the cleanliness factor of spatial production had a significant positive effect on the customer's revisit intention, and the cleanliness and differentiation factor of spatial production had a significant positive effect on the customer's word-of-mouth intention. Specific improvements in cleanliness and differentiation are as follows in order to promote revisit and word-of-mouth of beauty salon customers. First, in order to secure regular customers, the priority should be to create a clean space, and in the case of already existing hair salons, the revisit rate of existing customers can be increased by cleanly managing the space where the customer directly exists. Second, in order to attract new customers, it is believed that the effect of creating new customers through word-of-mouth can be increased by focusing on cleanliness as previously mentioned, and by using the brand's representative color so that customers can experience the brand's unique sensibility in the salon space. This study is meaningful because previous research on beauty salon space was insignificant, and it suggests that more attention should be paid to the cleanliness and differentiation of beauty salon space to revisit customers and attract new customers. However, in this study, several items that hinder reliability in relation to functionality were deleted, and in future studies, it is considered necessary to further revise and supplement functionality-related items so that the constituent concepts of spatial performance can be evaluated more closely.

A Long Skip Connection for Enhanced Color Selectivity in CNN Architectures.

Some recent studies show that filters in convolutional neural networks (CNNs) have low color selectivity in datasets of natural scenes such as Imagenet. CNNs, bio-inspired by the visual cortex, are characterized by their hierarchical learning structure which appears to gradually transform the representation space. Inspired by the direct connection between the LGN and V4, which allows V4 to handle low-level information closer to the trichromatic input in addition to processed information that comes from V2/V3, we propose the addition of a long skip connection (LSC) between the first and last blocks of the feature extraction stage to allow deeper parts of the network to receive information from shallower layers. This type of connection improves classification accuracy by combining simple-visual and complex-abstract features to create more color-selective ones. We have applied this strategy to classic CNN architectures and quantitatively and qualitatively analyzed the improvement in accuracy while focusing on color selectivity. The results show that, in general, skip connections improve accuracy, but LSC improves it even more and enhances the color selectivity of the original CNN architectures. As a side result, we propose a new color representation procedure for organizing and filtering feature maps, making their visualization more manageable for qualitative color selectivity analysis.

A guide to diagnosing colored resonances at hadron colliders

We present a comprehensive study on how to distinguish the properties of heavy dijet resonances at hadron colliders. A variety of spins, chiral couplings, charges, and QCD color representations are considered. Distinguishing the different color representations is particularly difficult at hadron colliders. To determine the QCD color structure, we consider a third jet radiated in a resonant dijet event. We show that the relative rates of three-jet versus two-jet processes are sensitive to the color representation of the resonance. We also show analytically that the antennae radiation pattern of soft radiation depends on the color structure of dijet events and develops an observable that is sensitive to the antennae patterns. Finally, we exploit a Convolutional Neural Network with Machine Learning techniques to differentiate the radiation patterns from different colored resonances and find encouraging results to discriminate them. We demonstrate our results numerically at a 14 TeV LHC, and the methodology presented here should be applicable to other future hadron colliders.

Reverse engineering as a modern methods of test bed modernization

The main purpose of the work is to present the individual stages of the reverse engineering process on the example of a dynamometer equipped with a single-cylinder research engine AVL 5804. The scope of work includes theoretical and practical aspects of measurements using 3D scanners. The Scantech KSCAN Magic hand-held optical scanner was used to measure the geometry of the dynamometer. The CAD model was created in the Autodesk Inventor program, and the correctness of its execution was checked by basing it on the scan and generating a scale of deviations along with a color representation of their size in the GOM Inspect program. The work was summarized with an example of upgrading the current stand based on a previously made design, which significantly shortened the process of modifying the intake system. <hr> <iframe width="560" height="315" src="https://www.youtube.com/embed/UT3n2IZL5ck?si=O5f0OFr3ThQaWC8Q" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>

Patient education: a colourful read?

Focus has been placed on improving ethnic and racial equality in dermatology in a number of areas including publishing and medical education, but what about patient education? In this letter, we analyse skin of colour representation in patient information leaflets from a number of dermatological bodies around the world.

Pseudo-Coloring as an Effective Tool to Improve the Readability of Images Obtained in an Electromagnetic Infiltration Process

The article presents a method of improving the readability of images obtained in the process of electromagnetic infiltration for sources processing information in a visual form (texts, images). The method uses the so-called technique of pseudo-coloring. The proposed method is based on LUT tables using the exponential function mapping the signal level of the compromising emanations into a point of the RGB color space. The conducted analyses showed that the proposed function determining the coefficients of the LUT table is an effective tool in the process of improving the level of visual perception, i.e., it increases the perception of shapes and the ability to extract elements from the background. In image processing, LUT can be identified as a color map, i.e., a structure that reflects the gray shade of an image pixel into its color representation in the RGB color space. The proposed method assumes the use of exponential functions for this reflection. As an assessment of the effectiveness of the proposed methods of pseudo-coloring images, both a subjective assessment based on the visual perception of a group of observers and an analytical assessment, which was carried out by analyzing the contrast of the assessed images, were adopted. This allowed for the same assessment and usefulness of the proposed function in determining the RGB value in the process of pseudo-coloring of images obtained during electromagnetic infiltration. The obtained results confirmed that the proposed method significantly improves contrast parameter of images, which is also confirmed by the visual assessment of these images.

Packaging of ready-to-eat products: a mix research approach for exploring aesthetic element influence on brand preference

PurposePackaging design has the power to convey persuasive and functional benefits, thereby inducing the brand preference as per empirical studies, but not much has been studied in detail about aesthetic aspects of packaging.

Colour as Symbols in the Select Works of Yann Martel

Colours can draw an identity to all living things. Natural colours can either calm down or disturb a person’s inner Self. At the times of crisis, it tends to give the individual soul wit and hope. Colours also have alchemical significance and can impact every man’s mind in certain ways. Colour representations have been used by many symbolists throughout literary history from the past to the present. Symbolists point out the importance of symbols in the poems of symbolist poetry. Moreover, the use of colour symbolism in literature contributes to the treasure of literary forms. In Canadian literature, Yann Martel holds a prominent position for his adaption of symbols and uses them to portray the inner quest of his characters. Frequently, his symbolism embodies a deep search for a spiritual quest with a religious component. Colour is one of the most important aspects in deciphering the psyche of his heroes. He has constructed various symbolic interpretations that exhibit the spiritual longing of individuals. Many colours like red, black, white, green, orange, etc have been used as symbolic representations to decode the mind set and religious beliefs. Among them, black and white colours play a vital role in an in-depth portrayal of the leading characters. The religious quest of the characters has been satisfied through the identification of colour representations and ancient relics. They were satisfied at the end. Hence, his works depict that colours have symbolic dramatic elements that naturally novelize the central theme of the search for Self. It also emphasizes the development of the Self with the supremacy of faith in the Almighty God. This paper deciphers the black and white colour symbols in the novels, “Self”, “Life of Pi”, “Beatrice and Virgil”, and “The High Mountains of Portugal” of Yann Martel.

Analyzing image-based political propaganda in referendum campaigns: from elements to strategies

Due to the increasing prominence of social network services, political communication has experienced a paradigm shift. To communicate with internet users, politicians, candidates, and political organizations create fan pages. Initially, they provide text-only material on their pages; later, to increase engagement, they include photos, images, and videos. This paper investigates image-based political images in Taiwan for the first time during a nationwide referendum. Unlike an election, a referendum is a policy-based vote. We evaluate over 2000 Facebook images shared by the two most prominent political parties in order to comprehend the aspects of images and the tactics of political organizations. In addition, we examine the textual content, objects, and colors of the collected data. We find that the characteristics of propaganda materials vary between political groups. Nonetheless, the color strategies employed by both sides are equivalent, with each side utilizing its own representative colors for consolidation and the opponent’s colors for attacking.

Assessment of Color Reproducibility and Mitigation of Color Variation in Whole Slide Image Scanners for Toxicologic Pathology.

Digital pathology workflows in toxicologic pathology rely on whole slide images (WSIs) from histopathology slides. Inconsistent color reproduction by WSI scanners of different models and from different manufacturers can result in different color representations and inter-scanner color variation in the WSIs. Although pathologists can accommodate a range of color variation during their evaluation of WSIs, color variability can degrade the performance of computational applications in digital pathology. In particular, color variability can compromise the generalization of artificial intelligence applications to large volumes of data from diverse sources. To address these challenges, we developed a process that includes two modules: (1) assessing the color reproducibility of our scanners and the color variation among them and (2) applying color correction to WSIs to minimize the color deviation and variation. Our process ensures consistent color reproduction across WSI scanners and enhances color homogeneity in WSIs, and its flexibility enables easy integration as a post-processing step following scanning by WSI scanners of different models and from different manufacturers.

Photography in dermatology - a scoping review: Practices, skin of color, patient preferences, and medical-legal considerations.

Clinical photography is essential in dermatology. However, a comprehensive literature review of photography in dermatology is lacking. This scoping review aims to summarize the literature regarding photography practices in dermatology, photography of skin of color, patient preferences, and medical-legal considerations. A search was conducted utilizing Embase, MEDLINE, PubMed, and Evidence Based Medicine databases in accordance with the PRISMA extension for Scoping Reviews. In total, 33studies were summarized. Clinical photography is commonly used in biopsy site marking, assessment, diagnosis, disease monitoring, evaluation of treatment response, medical education, research, seeking advice from colleagues, and teledermatology. Although dermatologic photography remains devoid of skin of color representation, photographic considerations for darker skin are available. Most patients support medical photography, with a preference for clinical photographs to be taken by their own physicians, and for use of clinic/hospital-owned cameras over personal devices. Pertinent medical-legal issues include concerns around privacy, personal device use, and documentation of consent. Photography in dermatology is continuously evolving with broader applications. Improved practices and innovations will benefit individuals of various skin tones. Management of consent and privacy must be upheld to sustain the increasing ease of image capture and sharing.

Herby ziemskie na pieczęciach koronnych króla Stanisława Augusta

A wreath of territorial, and later also state and dynastic coats of arms, as an element of the composition of Polish royal seals, appeared at the turn of the 14th and 15th centuries. Initially, it was placed on the seals of majesty, later on the broad (chancellor's) seals of the Crown and Lithuania, and from the times of John Casimir also on the small (sub-chancellor) Crown seals. A set of these coats of arms was created during the reign of King Michael. In general, however, in the field of territorial heraldry, it was characterized by quite high stability, and the land coats of arms introduced to it in the Jagiellonian times functioned without major changes until the reign of Stanisław August. This king used two sets of state seals. The first, created for the coronation in 1764, was a continuation of traditional patterns. The changes concerned only the coat of arms in the second set of seals made in 1780. They concerned two areas: the content and the form of presenting the signs. In the first, the markings of the former fief areas, which were no longer associated with the Crown, were updated: the coat of arms of the Moldavian fief was replaced with the coat of arms of the Kalisz Voivodeship, and the coat of arms of the Pomeranian fief with the coat of arms of Livonia. In the aspect of form, hatching of signs was used for the first time in state sigillography. Although hatching appears already on Wettin's seals, it was not used on Polish state seals. As a result, the seals created in 1780 are the first official color representation of the coats of arms of the lands of the Kingdom of Poland. Breaking with the existing tradition, the creator of the seal, Jan Filip Holzhaeusser, also reversed the arrangement of figural emblems, which until then had been directed towards the central element of the image (i.e., towards the figure of the enthroned ruler, or the Polish Eagle), and also changed the shape of some emblems to forms known from earlier times, later rejected. Enigmatic in this context is the small crown seal of this king, known from one of the collector's imprints, probably made in 1785. Its uniqueness, apart from the lack of confirmation of wider use, prove modifications in the coat of arms, unjustified on the grounds of Polish territorial heraldry.

Hybrid High Dynamic Range Imaging fusing Neuromorphic and Conventional Images.

Reconstruction of high dynamic range image from a single low dynamic range image captured by a conventional RGB camera, which suffers from over- or under-exposure, is an ill-posed problem. In contrast, recent neuromorphic cameras like event camera and spike camera can record high dynamic range scenes in the form of intensity maps, but with much lower spatial resolution and no color information. In this paper, we propose a hybrid imaging system (denoted as NeurImg) that captures and fuses the visual information from a neuromorphic camera and ordinary images from an RGB camera to reconstruct high-quality high dynamic range images and videos. The proposed NeurImg-HDR+ network consists of specially designed modules, which bridges the domain gaps on resolution, dynamic range, and color representation between two types of sensors and images to reconstruct high-resolution, high dynamic range images and videos. We capture a test dataset of hybrid signals on various HDR scenes using the hybrid camera, and analyze the advantages of the proposed fusing strategy by comparing it to state-of-the-art inverse tone mapping methods and merging two low dynamic range images approaches. Quantitative and qualitative experiments on both synthetic data and real-world scenarios demonstrate the effectiveness of the proposed hybrid high dynamic range imaging system. Code and dataset can be found at: https://github.com/hjynwa/NeurImg-HDR.

ECG Arrhythmia Classification Using Recurrence Plot and ResNet-18

Cardiovascular diseases are the leading cause of death worldwide, claiming approximately
 17.9 million lives each year. In this study, a novel CAD system to detect and classify electrocardiogram (ECG) signals is presented. Designed system employs the recurrence plot (RP) approach that transforms a ECG signal into a 2D representative colour image, finally performing their classifications via employment of Deep Learning architecture (ResNet-18). Novel system includes two steps, where the first step is the preprocessing one, which performs segmentation of the data into two-second intervals, finally forming images via the RP approach; following, in the second step, the RP images are classified by the ResNet- 18 network. The proposed method is evaluated on the MIT-BIH arrhythmia database where 5 principal types of arrhythmias that have medical relevance should be classified. Novel system can classify the before-mentioned quantity of diseases according to the AAMI Standard and appears to demonstrate good performance in terms of criteria: overall accuracy of 97.62%, precision of 95.42%, recall of 95.42%, F1-Score of 95.06%, and AUC of 95.7% that are competitive with better state-of-the-art systems. Additionally. the method demonstrated the ability in mitigating the problem of imbalanced samples.

Exploration of Experimental, Theoretical, Molecular Docking, and Electronic Excitation Studies of Carboxylate-Appended (2-Pyridyl)Alkylamine Ligand †

‘In this study, we employed density functional theory (DFT)/B3LYP method with a 6-311++G(d,p) basis set to analyze the infrared and UV spectra of a carboxylate-appended (2-pyridyl)alkylamine ligand. The FT-IR spectra were recorded within the range of 4000–500 cm-1. Geometrical parameters, energies, and wavenumbers were determined, and the fundamental vibrations were assigned based on the potential energy distribution (PED) of the vibrational modes. The UV spectrum of the compound was measured in various solvents, namely DMSO, CHCl3, and CH3OH. The 1H-NMR shifts were estimated using the GIAO method, and the results were compared to experimental spectra. To further investigate the electronic properties, including excitation energies, absorption wavelengths, and highest occupied molecular orbital (HOMO)–lowest unoccupied molecular orbital (LUMO) energies, we employed the DFT/B3LYP approach. The degree of electron localization was assessed through analysis of the ELF diagram. Additionally, a molecular electrostatic potential (MEP) was generated, and a 3-D color representation was utilized to visualize reactive sites. Lastly, a biological study involving molecular docking was conducted using six different receptors in order to identify optimal ligand-protein interactions and assess drug similarities.’

GD04 Patient education for all! Skin of colour ­under-represented again

Abstract Disparities in healthcare provision have a detrimental impact on health outcomes, which have been suffered by many patient cohorts, whether they are defined socially, economically or by the colour of their skin (Buster KJ, Stevens EI, Elmets CA. Dermatologic health disparities. Dermatol Clin 2012; 30:53–9). In the field of dermatology, we rely hugely on visual presentations. As dermatologists, the visible manifestations of disease, and their evolution, are fundamental to how we formulate diagnoses and treatment strategies. Similarly, visual depiction is important for patients to garner a wider understanding of their condition. This study aimed to analyse skin colour representation in patient information resources for a number of inflammatory conditions, including acne, atopic dermatitis, hidradenitis suppurativa, psoriasis and rosacea. Resources from multiple dermatological bodies including the British Skin Foundation, Irish Skin Foundation, American Academy of Dermatology Association, Canadian Dermatology Association, Dermatology Society of South Africa and the Australasian College of Dermatology were reviewed. Hard-copy pamphlets published by the associations were analysed; where pamphlets were unavailable, websites pertaining to each inflammatory condition were included. Images were divided by Fitzpatrick skin type into two categories: Fitzpatrick skin types I–IV and Fitzpatrick skin types V/VI. There is no formal definition of skin of colour, and for the purposes of this study, we referred to Fitzpatrick skin types V/VI. In total, 115 images were reviewed. People with skin of colour were represented in 5% (n = 6) of the images. This stark over-representation of Fitzpatrick skin types I–IV highlights the lack of inclusivity in current patient education resources. Consequently, patients with skin of colour may feel overlooked. This may foster a poor rapport between patients and physicians and could lead to mistrust and reduced engagement with healthcare services. Dermatological communities must join the global effort to eliminate racial disparities. The first steps have already been taken by many, in publishing and medical education, including the British Journal of Dermatology, which aims to enhance resources to study, describe and improve care for people with skin of colour (Guckian J, Ingram JR, Rajan N, Linos E. Dermatology is finally talking about race. Br J Dermatol 2021; 185:875–6). Patient information resources are another facet of our practice that need focus and reform. We must improve approachability, inclusiveness and trust within our specialty and work towards the overarching aim of delivering healthcare that is racially just.

Automated digital color restitution of mural paintings using minimal art historian input

Digital color restitution aims to digitally restore the original colors of a painting. Existing image editing applications can be used for this purpose, but they require a select-and-edit workflow and thus they do not scale well to large collections of paintings or different regions of the same painting. To address this issue, we propose an automated workflow that requires only a few representative source colors and associated target colors as input from art historians. The system then creates a control grid to model a deformation of the CIELAB color space. Such deformation can be applied to arbitrary images of the same painting. The proposed approach is suitable for restituting the color of images from a large photographic campaign, as well as for the textures of 3D reconstructions of a monument. We demonstrate the benefits of our method on a collection of mural paintings from a medieval monument.
