Review: Facial Anthropometric, Landmark Extraction, and Nasal Reconstruction Technology

Facial anthropometrics are measurements of human faces and are important figures that are used in many different fields, such as cosmetic surgery, protective gear design, reconstruction, etc. Therefore, the first procedure is to extract facial landmarks, then measurements are carried out by professional devices or based on experience. The aim of this review is to provide an update and review of 3D facial measurements, facial landmarks, and nasal reconstruction literature. The novel methods to detect facial landmarks including non-deep and deep learning are also introduced in this paper. Moreover, the nose is the most attractive part of the face, so nasal reconstruction or rhinoplasty is a matter of concern, and this is a significant challenge. The documents on the use of 3D printing technology as an aid in clinical diagnosis and during rhinoplasty surgery are also surveyed. Although scientific technology development with many algorithms for facial landmarks extraction have been proposed, their application in the medical field is still scarce. Connectivity between studies in different fields is a major challenge today; it opens up opportunities for the development of technology in healthcare. This review consists of the recent literature on 3D measurements, identification of landmarks, particularly in the medical field, and finally, nasal reconstruction technology. It is a helpful reference for researchers in these fields.

Coarse-grained Hamiltonian and effective one component theory of colloidal suspensions

We develop a theory to trace out the solvent degrees of freedom from the grand partition function of colloid-solvent mixtures. Our approach to coarse-graining is based on density functional formalism of density profile and the grand thermodynamic potential of solvent. The solvent-induced interaction which is many-body in character is expressed in terms of two functionals; one that couples the solvent to the colloidal density distribution and the second represents the density–density correlation function of the solvent. The nature, strength, and range of the potential depend on these functionals and therefore on the thermodynamic state of the solvent. The solvent-induced contribution to free energy functional is also derived. A self-consistent procedure is developed to calculate the effective potential between colloidal particles, colloid-solvent, and colloid-colloid correlation functions. The theory is used to investigate both additive and nonadditive binary hard-sphere mixtures. Results are reported for the two systems for several values of packing fractions ηb and ηs and particles diameter ratio q=σsσb where symbols b and s refer to colloid and solvent, respectively. Several interesting features are found: The short-range attractive part of the potential shows non-monotonic dependence on ηb; when ηb is increased from zero, initially the potential becomes more attractive but beyond a certain value of ηb that depends on q, the attraction starts weakening. The repulsive peaks formed at R∼(1+12nq) where R is a distance between centers of colloidal particles expressed in units of σb and n is an integer, become stronger on increasing ηb. These results show that many-body contribution to the effective potential depends in a subtle way on packing fractions ηb,ηs, size ratio q, and on nature of the interaction model and makes a non-negligible contribution to the coarse-grained Hamiltonian.

Zinc Phosphate Nanoparticles: A Review on Physical, Chemical, and Biological Synthesis and their Applications.

Nanotechnology is considered one of the emerging fields of science that has influenced diverse applications, including food, biomedicine, and cosmetics. The production and usage of materials with nanoscale dimensions like nanoparticles are attractive parts of nanotechnology. Among different nanoparticles, zinc phosphate nanoparticles have attracted attention due to their biocompatibility, biosafety, non-toxicity, and environmental compatibility. These nanoparticles could be employed in various applications like anticorrosion, antibacterial, dental cement, glass ceramics, tissue engineering, and drug delivery. A variety of physical, chemical, and green synthesis methods have been used to synthesize zinc phosphate nanoparticles. All these methods have some limitations along with certain advantages. Chemical approaches may cause health risks and environmental problems due to the toxicity of hazardous chemicals used in these techniques. Moreover, physical methods require high amounts of energy as well as expensive instruments. However, biological methods are free of chemical contaminants and eco-friendly. This review is aimed to explore different methods for the synthesis of zinc phosphate nanoparticles, including physical, chemical, and more recently, biological approaches (using various sources such as plants, algae, and microorganisms). Also, it summarizes the practicable applications of zinc phosphate nanoparticles as anticorrosion pigment, dental cement, and drug delivery agents.

An analysis of convexity and starlikeness attributes for breaz integro-differential operator

The Geometric Theory of Analytic Functions (GTAF) is the attractive part ofcomplex analysis, which correlates with the rest of the themes in mathematics. Itsessential purpose is to formulate numerous classes of geometric analytic functions and todiscuss their geometric attributes. In continuation, the association between operatortheory and the GTAF area started to take shape and has remained a topic of wide attentiontoday. In the previous century, operator theory was extended to the complex open unit diskand has been applied to propose diverse sorts of generalizations of normalized analyticfunctions. As a result, the operator theory appears to be a good way to look for thingsin the GTAF area. Since then, the acquisition of geometric attributes by employingoperators has become a significant theme of research studies. The current studycenters on and investigates, in the classes of $\ell$-uniformly convex and starlikefunctions of order $\beta$, the convexity attribute by utilizing a modified Breazintegro-differential operator in the unit disk. Furthermore, in the class of analyticfunctions, some conditions that make the Breaz operator look like a star are looked into.

The Façade, the Face, and the Sympathies: Opening the Black Box of Symbolic Capital as a Source of Philanthropic Attractiveness

Although most studies on philanthropy have focused on corporate benefactors, limited attention has been given to beneficiaries and their characteristics. The literature thus falls short in explaining how the variance in the perceived value of those characteristics can condition the philanthropic attractiveness of recipients for donors. Drawing from Bourdieu’s concept of symbolic capital and qualitative insights drawn from our empirical context of philanthropy in the field of cultural production in the Russian Federation, we argue that the attractiveness of cultural organizations for potential corporate benefactors depends on a range of determinants, which we classify under the broad umbrellas of respectability and reputability. By using political orientation as a moderator, we show that, although respectability is an indiscriminately attractive part of symbolic capital, reputability, associated with artistic celebrity and renown, can become a deterrent to potential donors when it augments the risk of jeopardizing their relationship with the government. We also demonstrate that a board of trustees, which signals openness to stakeholder involvement, diminishes the returns of reputability for potential donors. We test our hypotheses using original and representative longitudinal data on 449 Russian theaters (2004–2011). Taking an indirect recursive approach to estimate models with high-dimensional fixed effects, we find strong support for our hypotheses across a variety of econometric specifications. Our research offers a unique focus on the beneficiary side of the beneficiary-benefactor relationship, which has both theoretical and practical implications for the literatures on corporate philanthropy, and cultural industries.

Water evacuations in remote tourist regions: evaluating case studies from natural hazards in North Patagonian lakes, Argentina.

The remote North Patagonian region is a sparsely populated territory and a world famous tourist destination located on the leeward side of the Andes Mountains. Recent disasters triggered by various types of geoenvironmental hazards (including volcanic eruptions, mass-wasting processes and extreme weather events) heavily disrupted ground transport networks in a region with already limited territorial accessibilities. All these catastrophes prompted the need to evacuate or assist a number of secluded visitors, locals and livestock extemporaneously on board of coastguards and tourist passenger-ships from the shores of the many glacial lakes that make up part of the regional attraction. Despite the recurrence of these types of events, water evacuations in the region continue to be spontaneous, improvised and hazardous procedures. This contribution reconstructs and assesses a number of recent local-scale cases of lake evacuations and assistances from a number of Patagonian urban centers, rural areas and tourist sites. For each case study, we systematically elaborated on the prime components of an evacuation process, which enabled us to recognize key achievements, failures and conditioning factors for managing emergencies via water transport, most of them inherent to the studied region. Some of the complexities to emerge from case studies referred to: complex hazard-related scenarios; limited ground-based accessibilities and risk of isolation; various inter- and intra-organizational issues, incidental to natural reserves and tourist regions; a wide range of particular demographic features; and the availability and vulnerability of water transport resources. We suggested fundamental and replicable recommendations for developing water evacuation plans, also identifying forthcoming problems to solve in order to improve the management of emergencies through this alternative means of transport.Electronic supplementary materialSupplementary material (Appendix 1) is available in the online version of this article at 10.1007/s11629-021-7207-3

Beauty is in the Eye of the Beholder: Self-Perception of Physical Attractiveness Among Secondary School Adolescents

Abstract This study investigated body characteristics and gender differences that contribute to self-perception of physical attractiveness among adolescents. Quantitative data were collected with a questionnaire administered to 430 adolescents aged 15 to 17 years selected through a multistage sampling technique from secondary schools in Ile-Ife, Nigeria. The questionnaire included the Physical Attractiveness Rating Scale (PARS) and the Physical Attribute Questionnaire (PAQ). Independent sample t-test, and Multiple Regression Analyses were used for analyses. Statistical significance was set at p < .05. The mean overall attractiveness rating on the PARS was 1.66 (SD = 0.11), with ears and face rated as the most attractive body parts. The mean attractiveness score on the PAQ was 19.34 (SD = 3.47). Male and female participants differed with self-perception of physical attractiveness on the PARS [t (428) = 3.13 p = .003]; females perceived some body characteristics, namely mouth (t = 3.52; p < .05), teeth (t = 3.04; p < .05), nose (t = 2.40; p < .05), face (t = 1.98; p < .05), hair texture (t = 2.41; p < .05), hips (t = 3.85; p < .05) and thighs (t = 2.47; p < .05) as more attractive than males. Participants’ evaluation of individual body characteristics predicted self-perception of physical attractiveness (F = 2.85, p < .05, R2 = 0.16 and Adjusted R2 = 0.10). Study concluded that evaluation of individual body characteristics influenced self-perceived physical attractiveness. Gender influenced the perception of some specific body characteristics and overall physical attractiveness among studied adolescents.

Taking a closer look at body processing in binge eating disorder – Influence of BMI and eating pathology

Individuals with binge eating disorder (BED) show preferred attention allocation towards their own (vs. another) body, and towards self-disliked (vs. self-liked) body parts. It remains unclear whether these gaze patterns are a consequence of underlying eating pathology or increased weight. In this study, women with BED (N = 73), overweight (N = 38) and healthy weight (N = 42) female control groups (CG) performed two eye-tracking paradigms using pictures of their own and a control-body. In task 1 (processing their own vs. a control-body), the BED group displayed a stronger preference for the own body during more automatic processing relative to the overweight CG, whereas the healthy weight CG showed a balanced attention distribution between both bodies. In task 2, all groups showed a bias towards the most unattractive relative to the most attractive part of their own body. This was strongest in the BED and overweight groups, but only the BED group showed a negative bias towards the control-body. Results indicate a stronger self-focused and deficit-oriented bias in the BED group but also some abnormalities in overweight individuals. Future studies should test whether these biases are modifiable, and whether their modification improves body image.

Isotropic and anisotropic collision-induced light scattering spectra of krypton gas simultaneously fitted by ground state interatomic potential

Isotropic and anisotropic binary collision-induced light scattering spectra of gaseous krypton obtained at room temperature are analyzed in terms of different interatomic potentials, both reference and recent, and trace and anisotropy models of interaction-induced polarizability. The spectral intensities obtained numerically at low frequencies are determined by bound and free transitions. At intermediate and high frequencies, the spectra are sensitive to both the attractive part of the potential and to short-range values of the trace or anisotropy. An empirical interatomic potential for the krypton gas interaction is developed by simultaneously fitting the Barker et al. (BFW) and modified Tang-Toennies (MTT) potentials to thermophysical and transport properties over a wide temperature range. The quality of the present potentials was checked by comparison between the calculated and experimental vibrational energy levels. The results show that these are the most accurate potentials reported to date for this system, both for the reproduction of spectral line shapes and spectral moments.

TRANSFORMATION OF THE SUBURBAN AREA OF THE CITY OF AKTOBE

The development of large cities affects suburban settlements. Territories in suburbs are diverse and variable in size, functions and combinations, the nature of production and distribution of transport. For the last ten years, suburban settlements have begun to transform due to urban overpopulation. There are spontaneous elements in the development of processes that lead to the growth of suburban areas and they are used inefficiently effectively. The relevance of the study was due to the need to analyze the suburbs as part of the city. The article analyzes the structure and dynamics of development of the suburban area near the city of Aktobe. The development of suburban areas is one of the elements of changing the economy of the city and determines their development. The study used statistical, comparative and analytical, isochronous methods. Suburban zone Aktobe represents a geodemographic interest in the strength of its formation and dimensions. The most active and attractive part of the suburban zone is located 15-30 km from the center of Aktobe, between 40-minute and half-hour isochrons. In the following years, the city of Aktobe is rapidly developing. The main issues of the development of Aktobe: the division of the city into functional zones, town planning, development of the main infrastructure, protection of recreational zones, the formation of green zones, etc. SWOT-analysis of settlements around Aktobe showed that one of the strong sides is a favorable transport and logistics situation. There were other strong and weak sides, opportunities and obstacles.

Clustering in Mixtures of SALR Particles and Hard Spheres with Cross Attraction.

Self-assembling complex fluids are often modeled as particles with effective competing isotropic interactions, combining a short-range attraction (SA) followed by a longer-range repulsion (LR). For moderately low temperatures and densities, SALR particles form clusters in equilibrium, at least provided that the potential parameters are appropriate. Here we inquire into the possibility that cluster formation in SALR fluids might be pushed by a foreign species even under thermodynamic conditions that would not allow for clusterization of the pure system. To this aim, we study by Monte Carlo simulations a mixture of hard-sphere two-Yukawa particles and hard spheres, with a cross interaction modeled by a square-well attraction, and we investigate the conditions of clustering in terms of strength of attraction and relative concentration of the two species. We find that clusters can occur in the mixture for the same temperature and density where the pure SALR fluid is almost structureless. In particular, we single out a cross attraction such that clusters are formed with a SALR concentration as low as 5%. We also find a situation where nearly pure droplets of hard spheres are held together by a shell of SALR particles. Conversely, we show that clustering can be undermined in the mixture under conditions for which this process takes place in the parent SALR fluid. Using a simple criterion, based on the second virial coefficients of the attractive part of interaction potentials (the so-called “reference attractive fluids”), we are able to predict accurately whether clustering is favored (or hindered) in the mixture, as compared to the pure SALR fluid.

Mesoscopic Inhomogeneities in Concentrated Electrolytes.

A mesoscopic theory for water-in-salt electrolytes combining density functional and field-theoretic methods is developed in order to explain the unexpectedly large period of the oscillatory decay of the disjoining pressure observed in recent experiments for the lithium bis(trifluoromethylsulfonyl)-imide (LiTFSI) salt [T. S. Groves et al., J. Phys. Chem. Lett.2021, 12, 1702]. We assumed spherical ions with different diameters and implicit solvent, inducing strong, short-range attraction between ions of the same sign. For this highly simplified model, we calculated correlation functions. Our results indicate that mesoscopic inhomogeneities can occur when the sum of the Coulomb and the water-mediated interactions between like ions is attractive at short and repulsive at large distances. We adjusted the attractive part of the potential to the water-in-LiTFSI electrolyte and obtained both the period and the decay rate of the correlations, in semiquantitative agreement with the experiment. In particular, the decay length of the correlations increases nearly linearly with the volume fraction of ions.

Screening of Absorbing Grains in Plasma with a Flow

The electrostatic shielding of a charged absorbing object (dust grain) in a flowing collisionless plasma is investigated by usingthe linearized kinetic equation for plasma ions with a point-sink term accounting for the ion absorption on the object. The effect ofabsorption on the attractive part of the dust grain potential distribution in plasma is investigated. For subthermal ion flows, the attractive part of the grain potential in the direction perpendicular to the ion flow can be significantly reduced or completely destroyed, depending on the absorption rate (proportional to the surface area of a grain). For superthermal ion flows, however, the effect of absorption on the grain attraction in the direction perpendicular to the ion flow is shown to be exponentially weak. It is thus argued that, in the limit of superthermal ion flow, the effect of absorption on the grain potential distribution in plasma can be safely ignored for typical grain sizes relevant to complex plasmas.

Thermodynamic or density scaling of the electrical conductivity of molten salts.

Thermodynamic or density scaling of high-pressure conductivities and molar conductivities of the high-temperature molten salts NaOH, and the alkali chlorides, bromides, and nitrates, from Na to Cs, taken from the literature, is found to be consistent with the simulations of Knudsen, Niss, and Bailey (KNB). They used a simple model fluid of point particles interacting through an interionic potential with a repulsive inverse power law part varying as r-9 and an attractive Coulombic part. This yields values between the limits 0.33-3 for the scaling parameter, γ. The Coulombic potential reduces the scaling parameter to values much lower than are normally found for molecular liquids, and KNB used this to explain the low values typically found for ionic liquids. Here, it is shown that the high-temperature molten salts examined behave similarly.

A miniaturised Ka/V dual band millimeter wave antenna for 5G body centric network applications

Body centric Networks (BCNs) are the most important and attractive part of the next generation (5G and beyond) wireless technologies having a plethora of applications in day to day life. However the design of antennas for BCNs is a challenging task. Such antennas should have small size, light weight, higher gain and larger bandwidth besides having a stable radiation pattern under the influence of human body effects. This paper presents a miniaturised Ka/V dual band mmWave microstrip antenna for 5G BCN applications. The antenna has very small dimensions of 2.28 × 3.06 × 0.14 mm3 and operates at 33.5 GHz (Ka band) and 60.8 GHz (V band). The performance of the antenna is examined for “Off-body, On-body and In-body” BCN application scenarios. The radiation pattern, return loss, peak gain and −10 dB bandwidth results reveal that the antenna performs quite well at all interested frequencies. A comparative study with state of art mmWave antennas also shows the effectiveness of the proposed antenna.

Local Culinary Entrepreneurship As The Development Of Regional Gastronomy And Urban Tourism

Tourism development efforts are currently being pursued through the concept of sustainable tourism with a community-based tourism approach, providing great opportunities for the community to participate in tourism development; produce tourism product development from businesses managed by the community. However, a way is still needed so that all these developments can continue to increase the number of tourist visits. The emergence of tourism as an academic part of tourism studies and education, encourages tourism potential to continue to be developed. Such an attraction makes Sate Bandeng a gastronomic tour. Which is one of the right ways to raise the potential of local culinary. This article aims to show the progress of tourism since before the concept of sustainable tourism was applied to the present. The research method used is a description with a qualitative approach. This study is based on a review of secondary sources through literature research and personal communication with several scholars in tourism and tourism business services. There are not many articles that discuss local culinary entrepreneurship as a development of regional gastronomy and part of an urban tourism attraction, while the development of sustainable tourism has allowed tourism to stand alone, and it seems that tourism with all its derivatives has gained independence as a field of academic study and as a Study Program in Higher Education in Indonesia.

Моделирование взаимосвязи пейзажно-эстетических качеств прибрежных ландшафтов

This paper presents a methodology for assessing the visual quality of coastal landscapes. The initial material was the data of a survey of the opinions of vacationers in the coastal zone of the southwestern coast of Lake Baikal about the landscapes aesthetic properties of their places of rest (aesthetics, diversity, harmony, exoticism, uniqueness, beauty, disturbance, colorfulness), individual components of the landscape (sky, relief, vegetation, water bodies) and their emotional state. Analysis of public opinion makes it possible to obtain a spatially differentiated view (representation) of the landscape and aesthetic qualities of coastal landscapes. The most attractive and most disturbed parts of the coastal zone have been identified. To understand the factors contributing to the formation of the aesthetic impression of the surrounding landscapes among respondents, multiple regression analysis was carried out using the Data Analysis module of Ms Excel. The resulting multiple regression model is characterized by a high comparability of the results of empirical data with their predicted values: the absolute value of the correlation between the aesthetic quality of the observed landscapes and their particular aesthetic qualities (properties) is 0.93, the average approximation error is 6.5 %. The aesthetic qualities of a landscape are an indicator of its “health”. For this reason, the results of assessing the visual properties of landscapes should be taken into account in assessing the recreational load on landscapes, in developing policy documents for the territorial and socio-economic development of municipalities and the Region.

STREET ART AS A DECORATION OF THE FACADES AND WALLS OF BUILDINGS IN SIVERSKODONETSK: PROBLEMS AND PERSPECTIVES

The article highlights the problem of the prewar development of street art in modern cities of Ukraine using the example of Severskodonetsk as the regional center of Luhansk region. The research notes that modern industrial cities of Donbas are often monotonous and faceless in terms of architectural construction involving technologically outdated building structures, poorly planned and weakly structured territory, and growing social problems of residents. It is considered that the task of urban planners and architects is to create comfortable living conditions for dwellers of residential areas, turning these poor areas into attractive parts of the city. The prewar situation with street art in Severskodonetsk is analyzed. Street art in Severskodonetsk, its analysis, and recommendations for the development of street art in the city are examined. It is believed that in the war-zone region, it is necessary to pay attention to street art, which could not only significantly beautify the city’s appearance but also distract its residents, including many refugees, from negative thoughts. Taking into account the fact that after the war, its inhabitants will return to the city, including young people, it will be essential to pay more attention to the youth subculture and street art as one of these subcultures. It is noted that insight into the problem of street art as one of the brightest youth subcultures is one of the most important tasks in the modern city, so decorating street houses of modern cities and, hence, forming recommendations to solve this problem is a critical task today.

Extended law of corresponding states: square-well oblates

The vapour–liquid coexistence collapse in the reduced temperature, T r = T/T c , reduced density, ρ r = ρ/ρ c , plane is known as a principle of corresponding states, and Noro and Frenkel have extended it for pair potentials of variable range. Here, we provide a theoretical basis supporting this extension, and show that it can also be applied to short-range pair potentials where both repulsive and attractive parts can be anisotropic. We observe that the binodals of oblate hard ellipsoids for a given aspect ratio (κ = 1/3) with varying short-range square-well interactions collapse into a single master curve in the –ρ r plane, where , B 2 is the second virial coefficient, and v 0 is the volume of the hard body. This finding is confirmed by both REMC simulation and second virial perturbation theory for varying square-well shells, mimicking uniform, equator, and pole attractions. Our simulation results reveal that the extended law of corresponding states is not related to the local structure of the fluid.

Kotel Balkan – an oasis of the East Balkan geodiversity

The East Balkan offers picturesque mountain landscapes predetermined by а remarkable geological diversity: caves, waterfalls, karst springs and precipices, fossil deposits, stratigraphical, paleontological, tectonic and fossil slump phenomena. In its most attractive part, the Kotel Balkan, there are 28 natural landmarks, 3 protected areas and 2 reserves. Expanding the inventory with purely geological sites, such as fossils, olistostromes, thrusts, geological cycles and events, complemented by many historical sites and intangible cultural heritage (Karakachan minority traditions, craft and folklore festivals), the region of Kotel has excellent preconditions for a geopark development.
