Impact of fig maceration under various conditions on physicochemical and sensory attributes of wine vinegar: A comprehensive characterization study.

In this work, wine vinegars macerated with figs under different conditions have been characterized for the first time. Samples were analyzed by solid phase microextraction and gas chromatography coupled to mass spectrometry, sensory and physicochemical analysis. The results revealed that fig maceration of wine vinegars influenced the physicochemical, sensory, and volatile profiles of the final product, which were mainly affected by the fig amount (10, 20 or 30%), the fig type (fresh or dry) and the base wine vinegar (young or aged) used, and to a lesser extent the way the fig was added (crushed or chopped). The maceration, regardless the conditions used, increased the fruity notes, overall taste and visual impression, the tonality, total polyphenols and sugar content, and the presence of some volatile compounds, mainly terpenes and ketones, such as (Z)-p-mentha-2,8-dien-1-ol, or β-damascenone. Therefore, maceration increased the organoleptic complexity, which could enhance the acceptability of consumers towards these products. PRACTICAL APPLICATION: This research studied how wine vinegars macerated with figs affect in different ways their taste, smell, and chemical properties. Thus, the results showed that these wine vinegars made with fig maceration by using different amounts and types of figs, as well as the type of vinegar used, changed their characteristics, making them smell and taste fruitier and more pleasant. This could be useful for making better-tasting and more appealing vinegars for consumers who enjoy unique and enhanced flavors in their food.

Parallel linearized ADMM with application to multichannel image restoration and reconstruction

Many large-scale regularized inverse problems in imaging such as image restoration and reconstruction can be modeled as a generic objective function involves sum of nonsmooth but proximable terms, which are usually linear-operator-coupled. For the solution of these problems, a parallel linearized alternating direction method of multipliers (PLADMM) is proposed in this paper. At each step of the proposed algorithm, the proximity operators of the nondifferential terms are called individually. This leads to a highly parallel algorithm structure, where most sub-steps can be simultaneously solved. Profiting from the linearization step, the linear inverse operation is excluded. The convergence property of the proposed method is analyzed. The image deblurring, inpainting, and pMRI reconstruction experiments show that the proposed method has vast applicable vistas. Compared with the state-of-the-art methods, such as PADMM [21], FTVD-v4 [22], PPDS [33], FUSL [8], LADM [36], and ALADMM [27], it gains competitive results both in terms of quantitative indicators, such as PSNR or SSIM, and in terms of visual impression.

Image reconstruction parameters and the standardized uptake value ratios in brain amyloid PET.

The present study investigated various image reconstruction protocols for amyloid PET using phantom test criteria published by the Japanese Society of Nuclear Medicine (JSNM) and compared them with the composite standardized uptake value ratio (cSUVR) in clinical imaging. Hoffman 3D phantoms and cylindrical phantoms were collected for 30 min according to the JSNM guidelines. Images were created under various reconstruction protocols by three physical evaluation items in the guidelines and were assessed: gray matter/white matter contrast (%contrast), uniformity (SDuROImean), and image noise [coefficient of variation (CV)]. We compared the cSUVR of images reconstructed under 15 protocols using 18F-flutemetamol and 18F-florbetapir in 15 cases each and the guidelines for physical evaluation of reconstruction parameters. No significant differences were observed in cSUVR between reconstruction protocols that satisfied the guidelines' criteria for %contrast and CV and those that did not; however, the visual impression of images differed. SDuROImean, which evaluated uniformity, met the criteria in all data. Reconstruction protocols should be selected appropriately using guidelines and other information, as cSUVR remains largely the same even if the visual impression of the images differs between different reconstruction protocols. When the relationship between %contrast and CV is expressed in terms of several reconstruction protocols, the graph shows a curved shape, and the optimal protocols for both %contrast and CV are near its center. Since cSUVR is similar to optimal parameters, even under parameters outside this range, multiple parameters need to be considered when selecting image reconstruction protocols for amyloid PET.

Wartime experience of visual impressions: K. A. Korovin and the problem of camouflaging positions at the front during World War I

During World War I the development of new methods for camouflaging the troops demanded the involvement of not only military professionals but also of the artists. Thus, a famous artist and Academician of Painting, Konstantin Alekseevich Korovin (1861–1939), cooperated with the paint-disguise and camouflage service established on the South-West Front on the initiative of brothers A. N. and N. N. Suchkov. The documents deposited at the Russian State Military Historical Archives reflect Korovinʼs interest in the problems of military camouflage, his trips to the front and his inventions. In the documents published here (the letters to the Suchkov brothers; a memorandum and an explanatory report to the chief of engineers of the armies of the South-West Front; instructions for the so-called “color finder” for determining the color of paint after drying) the artist outlined the problems of camouflage at the front, gave advice on the best ways of concealing positions (camouflaging trenches by paint spraying, setting up observation points that merge with the terrain, the use of camouflage nets). Korovin was aware of the innovations in camouflage in the armies of Russiaʼs allies, and urged to adopt the best of what they had. According to Korovin, the leadership of camouflage teams should be entrusted to competent officers familiar with the rules and specifics of perception of color combinations. The documents suggest that Korovin was one of the pioneers in the military science of camouflage in Russia.

Simulation training in mammography with AI-generated images: a multireader study.

The interpretation of mammograms requires many years of training and experience. Currently, training in mammography, like the rest of diagnostic radiology, is through institutional libraries, books, and experience accumulated over time. We explore whether artificial Intelligence (AI)-generated images can help in simulation education and result in measurable improvement in performance of residents in training. We developed a generative adversarial network (GAN) that was capable of generating mammography images with varying characteristics, such as size and density, and created a tool with which a user could control these characteristics. The tool allowed the user (a radiology resident) to realistically insert cancers within different regions of the mammogram. We then provided this tool to residents in training. Residents were randomized into a practice group and a non-practice group, and the difference in performance before and after practice with such a tool (in comparison to no intervention in the non-practice group) was assessed. Fifty residents participated in the study, 27 underwent simulation training, and 23 did not. There was a significant improvement in the sensitivity (7.43 percent, significant at p-value = 0.03), negative predictive value (5.05 percent, significant at p-value = 0.008) and accuracy (6.49 percent, significant at p-value = 0.01) among residents in the detection of cancer on mammograms after simulation training. Our study shows the value of simulation training in diagnostic radiology and explores the potential of generative AI to enable such simulation training. Using generative artificial intelligence, simulation training modules can be developed that can help residents in training by providing them with a visual impression of a variety of different cases. Generative networks can produce diagnostic imaging with specific characteristics, potentially useful for training residents. Training with generating images improved residents' mammographic diagnostic abilities. Development of a game-like interface that exploits these networks can result in improvement in performance over a short training period.

VISUAL IMPRESSIONS AND INTERVENTIONS IN NON-PLACE SPACES WITHIN MAQBOOLPURA: A CASE STUDY OF AN INFORMAL SETTLEMENT IN AMRITSAR

Informal settlements are a common phenomenon in Indian cities, where the urban poor carve out their own spaces outside the formal planning system. Maqboolpura is one of the oldest informal settlements in Amritsar, which grapples with various urban design issues such as a poor built environment, inadequate open spaces, and ignorant public places. These issues affect the livability of the people of informal settlements. Non-places, characterized by a lack of identity and social relations, are prevalent in Maqboolpura due to their marginalization. This paper aims to explore the visual impressions of public spaces and the potential of redesigning the non-places in Maqboolpura to improve livability. This paper analyzes the visual impressions through the spatial structure of streets and the patterns of use by the dwellers in Maqboolpura. It proposes the design interventions to improve the non-places, such as creating multifunctional and flexible community spaces with the help of art and landscape in the process. The paper argues that improving the visual appeal of public spaces and reimagining the non-places can contribute to the adaptive livability of Maqboolpura. It covers the core aspects of public spaces inside the informal settlements to improve the quality of spaces for the urban poor.

3D imaging of SARS-CoV-2 infected hamster lungs by X-ray phase contrast tomography enables drug testing

X-ray Phase Contrast Tomography (XPCT) based on wavefield propagation has been established as a high resolution three-dimensional (3D) imaging modality, suitable to reconstruct the intricate structure of soft tissues, and the corresponding pathological alterations. However, for biomedical research, more is needed than 3D visualisation and rendering of the cytoarchitecture in a few selected cases. First, the throughput needs to be increased to cover a statistically relevant number of samples. Second, the cytoarchitecture has to be quantified in terms of morphometric parameters, independent of visual impression. Third, dimensionality reduction and classification are required for identification of effects and interpretation of results. To address these challenges, we here design and implement a novel integrated and high throughput XPCT imaging and analysis workflow for 3D histology, pathohistology and drug testing. Our approach uses semi-automated data acquisition, reconstruction and statistical quantification. We demonstrate its capability for the example of lung pathohistology in Covid-19. Using a small animal model, different Covid-19 drug candidates are administered after infection and tested in view of restoration of the physiological cytoarchitecture, specifically the alveolar morphology. To this end, we then use morphometric parameter determination followed by a dimensionality reduction and classification based on optimal transport. This approach allows efficient discrimination between physiological and pathological lung structure, thereby providing quantitative insights into the pathological progression and partial recovery due to drug treatment. Finally, we stress that the XPCT image chain implemented here only used synchrotron radiation for validation, while the data used for analysis was recorded with laboratory μ\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\mu$$\\end{document}CT radiation, more easily accessible for pre-clinical research.

Multiparametric quantification and visualization of liver fat using ultrasound

ObjectivesSeveral ultrasound measures have shown promise for assessment of steatosis compared to traditional B-scan, however clinicians may be required to integrate information across the parameters. Here, we propose an integrated multiparametric approach, enabling simple clinical assessment of key information from combined ultrasound parameters. MethodsWe have measured 13 parameters related to ultrasound and shear wave elastography. These were measured in 30 human subjects under a study of liver fat. The 13 individual measures are assessed for their predictive value using independent magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF) measurements as a reference standard. In addition, a comprehensive and fine-grain analysis is made of all possible combinations of sub-sets of these parameters to determine if any subset can be efficiently combined to predict fat fraction. ResultsWe found that as few as four key parameters related to ultrasound propagation are sufficient to generate a linear multiparametric parameter with a correlation against MRI-PDFF values of greater than 0.93. This optimal combination was found to have a classification area under the curve (AUC) approaching 1.0 when applying a threshold for separating steatosis grade zero from higher classes. Furthermore, a strategy is developed for applying local estimates of fat content as a color overlay to produce a visual impression of the extent and distribution of fat within the liver. ConclusionIn principle, this approach can be applied to most clinical ultrasound systems to provide the clinician and patient with a rapid and inexpensive estimate of liver fat content.

Accurate and safe diagnosis and treatment of neoplastic biliary lesions using a novel 9F and 11F digital single-operator cholangioscope.

Background and study aims Digital single-operator cholangioscopy (DSOC) allows the diagnosis of biliary duct disorders and treatment for complicated stones. However, these technologies have limitations such as the size of the probe and working channel, excessive cost, and low image resolution. Recently, a novel DSOC system (eyeMAX, Micro-Tech, Nanjing, China) was developed to address these limitations. We aimed to evaluate the usefulness and safety of a novel 9F and 11F DSOC system in terms of neoplastic diagnostic accuracy based on visual examination, ability to evaluate tumor extension and to achieve complete biliary stone clearance, and procedure-related adverse events (AEs). Patients and methods Data from ≥ 18-year-old patients who underwent DSOC from July 2021 to April 2022 were retrospectively recovered and divided into a diagnostic and a therapeutic cohort. Results A total of 80 patients were included. In the diagnostic cohort (n = 49/80), neovascularity was identified in 26 of 49 patients (46.9%). Biopsy was performed in 65.3% patients with adequate tissue sample obtained in 96.8% of cases. Biopsy confirmed neoplasia in 23 of 32 cases. DSOC visual impression achieved 91.6% sensitivity and 87.5% specificity in diagnosing neoplasms. In the therapeutic cohort (n = 43/80), 26 of 43 patients required lithotripsy alone. Total stone removal was achieved in 71% patients in the first session. Neither early nor late AEs were documented in either the diagnostic or therapeutic cohort. Conclusions The novel DSOC device has excellent diagnostic accuracy in distinguishing neoplastic biliary lesions as well as therapeutic benefits in the context of total stone removal, with no documented AEs.

Gait pattern can alter aesthetic visual impression from a third-person perspective

Beauty is related to our lives in various ways and examining it from an interdisciplinary approach is essential. People are very concerned with their appearance. A widely accepted beauty ideal is that the thinner an individual is, the more beautiful they are. However, the effect of continuous motion on body form aesthetics is unclear. Additionally, an upright pelvic posture in the sagittal plane during walking seems to affect the aesthetic judgments of female appearance. We directly analyzed the influence of body form and walking pattern on aesthetic visual impressions from a third-person perspective with a two-way analysis of variance. Captured motion data for three conditions—upright pelvis, normal pelvis, and posteriorly tilted pelvic posture—were applied to each of three mannequins, representing thin, standard, and obese body forms. When participants watched stimulus videos of the mannequins walking with various postures, a significantly higher score for aesthetic visual impression was noted for an upright pelvic posture than for a posteriorly tilted pelvic posture, irrespective of body form (F(2, 119) = 79.89, p < 0.001, η2 = 0.54). These findings show that the third-person perspective of beauty can be improved even without being thin by walking with an upright pelvic posture.

Development and validation of the effective CNR analysis method for evaluating the contrast resolution of CT images

Contrast resolution is an important index for evaluating the signal detectability of computed tomographic (CT) images. Recently, various noise reduction algorithms, such as iterative reconstruction (IR) and deep learning reconstruction (DLR), have been proposed to reduce the image noise in CT images. However, these algorithms cause changes in the image noise texture and blurred image signals in CT images. Furthermore, the contrast-to-noise ratio (CNR) cannot be accurately evaluated in CT images reconstructed using noise reduction methods. Therefore, in this study, we devised a new method, namely, “effective CNR analysis,” for evaluating the contrast resolution of CT images. We verified whether the proposed algorithm could evaluate the effective contrast resolution based on the signal detectability of CT images. The findings showed that the effective CNR values obtained using the proposed method correlated well with the subjective visual impressions of CT images. To investigate whether signal detectability was appropriately evaluated using effective CNR analysis, the conventional CNR analysis method was compared with the proposed method. The CNRs of the IR and DLR images calculated using conventional CNR analysis were 13.2 and 10.7, respectively. By contrast, those calculated using the effective CNR analysis were estimated to be 0.7 and 1.1, respectively. Considering that the signal visibility of DLR images was superior to that of IR images, our proposed effective CNR analysis was shown to be appropriate for evaluating the contrast resolution of CT images.

Light formed through urban morphology and different organism groups: First findings from a systematic review.

The prevailing implementation and usage of contemporary lighting technologies and design practices in cities have created over-illuminated built environments. Recent studies indicate that exposure to electric lighting effects formed through spatial characteristics has visual, physiological, and behavioural effects on both humans and non-humans, such as wildlife. In order to gain a better understanding of the impact that electric lighting has on space and different organism groups, a comprehensive literature review was conducted applying PRISMA 2020 systematic review guidelines. Results of the searches from various databases, such as Web of Science, PubMed and Scopus, identified 5260 related studies. A total of 55 papers connected to four themes: (1) urban morphology; (2) human visual impressions; (3) ecological impacts; and (4) design approaches and methods were analysed with a focus on urban morphology. The review provided the following general findings: lighting properties alone are inadequate to depict visual impressions of pedestrians, patterns formed through light interacting with spatial characteristics can contribute to understanding how spaces are visually perceived and help characterising the exposure of wildlife organisms to potential disturbances.

People’s conceptual environmental appraisals of urban space in daylight and electric light

Urban spaces should be resilient, inclusive and safe for all residents including children, elderly and vulnerable groups. This implies that urban planning, management and design should provide public spaces that support human needs of active mobility, social interaction and psychological restoration across seasonal and diurnal variation in natural light. Environmental psychology postulates that an understanding of how people experience or appraise an environment is a critical component in the relationship between urban design and human behaviour. In this conceptual paper we propose and discuss overarching (visual) impressions of the environment (environmental appraisals) that could be utilized to deepen the understanding of how people experience urban green spaces under different lighting conditions. In a certain setting, people respond to specific components of the environment; such perceived molecular environmental qualities make up the overall impression of the setting, and shape critical human-environment transactions fundamental to human well-being. The perceived stimuli are considered to act together to form the perceptual basis for higher order, molar aspects, so called conceptual environmental appraisals. We introduce Küller’s human-environment interaction model and Brunswik’s lens model to describe conceptual environmental appraisals. Recognising urban forests as important settings for physical active mobility, social interaction, and psychological restoration, we outline the theoretical underpinnings of three conceptual environmental appraisals: prospect – refuge pertaining to the perceived safety of the environment, environmental preferences, and the perceived restorative potential of the environment. The appraisals have been shown to be relevant in studies on electric lighting in urban space, and possible to assess by means of observer-based assessments also among children, elderly and vulnerable groups. Assessment outcomes may inform discussions on conflicting goals for sustainable development with regard to people’s health and well-being, energy use, light pollution and the welfare of other species in urban planning, management and design.

Hourglass, and: Corduroy is a Morning in America

Abstract: “Hourglass” combines images of erosion and bar-room pool to discuss concepts of breakage and the redemptive force of listening to stories, with a nod to the web/yarn-spinning spider. “Corduroy is a morning in America” uses visual, personal, and etymological impressions of corduroy—plus Reagan’s 1984 campaign line—to link a dawn ski run with concern over right-veering U.S. politics.

ANALYSIS OF CHANGES IN SENSORY PREFERENCES OF TOURISTS UNDER MARTIAL LAW

The study of changes in sensory preferences of tourists under martial law is important both for understanding the impact of military conflicts on people's psychology and behaviour, and for developing strategies for managing the tourism industry in conditions of instability and crisis. The aim of the study is to analyse the changes in tourists' sensory preferences due to the effects of the Russian-Ukrainian war. Two sociological surveys were used to analyse and draw conclusions on the changes in the sensory preferences of tourists in connection with the large-scale invasion of Russia. The first survey was conducted in November-December 2021 and January 2022, the second in September and October 2023, which was a continuation of the first. A chi-squared test was calculated to confirm the hypothesis of a difference in the answers given by respondents before and during the war. Confirmation of the hypothesis allowed to prove that when developing tourism products, companies should take into account changes in the sensory preferences of tourists. The study showed significant changes in the choice of tourist options by travellers under the influence of sensory sensations that were formed during the Russian-Ukrainian war. The cost of travel has become more important, cultural and walking tourism has lost popularity, while extreme and gastronomic tourism has gained popularity. Aromas and tastes have a greater impact on travellers' associative memory, while visual impressions remain important, with historical themes becoming more popular. It was concluded that the sensory preferences and emotional reactions of travellers differ significantly by age. Younger respondents (under 16 years old) prefer food and music the most, while the older group (over 50 years old) prefers cuisine, tastes and appearance. It is clear that tourism businesses need to adjust their services and marketing strategies to take into account these age-specific characteristics and differences in tourists' reactions to sensory stimuli. Tourism businesses can use the findings of this study to adapt their marketing strategies and tourist offerings to the changing sensory preferences and needs of tourists caused by the military conflict. This will allow them to attract and retain customers even in times of insecurity, instability and crisis.

Academic conference posters: Describing visual impression in pharmacy education

BackgroundAcademic conference posters are a key communication before journal articles. Attention to visual attributes can enhance academic poster communication. ObjectiveThis investigation's purpose was to create a visual impression measurement instrument, and then to describe and compare visual impression among scientific posters from an academic conference. MethodsA mixed-approach rubric was created to quickly measure visual impression of academic posters. Then, posters from a pharmacy education conference were retrospectively reviewed and scored. Visual impression was compared for traditional versus contemporary poster-formats. Various poster characteristics (poster-format, summary statement presence, abstract presence, wordiness, QR-code presence, logical sequencing, visuals) that might have impacted visual communication were coded. These characteristics were regressed onto visual impression scores. ResultsThree-hundred seventy-eight posters were scored with sound inter-rater reliability. Contemporary poster-format scored significantly higher than traditional. Poster-format, abstract absence, lack of wordiness, QR-code presence, logical sequencing, and number of visuals were significant when regressed. ConclusionPosters at one academic conference had varied visual impression. While a contemporary poster-format appeared more helpful, it was not a panacea; variation from poor through exemplary was seen with both poster-formats. Posters are not text-filled articles; displaying a combination of visuals/text clearly and concisely can help effective communication with academic posters.
