Published: May 2022

This article is devoted to the current trends in the creation of platforms and the formation of digital ecosystems as the next stage of their development. The subject area of the article is a digital platform for the development of logistics activities and bringing the process of organizing entrepreneurial activity to a more advanced, modern “digital” level. The purpose of the study: to substantiate that digital platforms form new algorithms for the interaction of logistics business participants and a new (or modern and digital) business model for the organization of entrepreneurial activity. The article considers a digital platform as a project, technology, product “on demand” or an integrated set of software products. The concepts of “platform”, “digital platform”, “digital ecosystem”, “digital transformation projects” and “transformational project” are revealed. The practical implementation of digital solutions in the logistics sphere is summarized, namely: projects “Electronic navigation seals”, “Robotic sorting”, “Digital assistant of the shunting dispatcher at marshalling yards”, “Technical vision”; products “Smart logistics Cargo”, “Smart Logistics Trans”, “Business Lines: Cargo Transportation” and the integrated software package TMS (Transportation Management System) and WMS (Warehouse Management System). Attention is drawn to the process of obtaining goods and services and how this familiar process with the use of information technology has been transformed into digital platforms. In conclusion, the tasks and functions of the platform are outlined, which is considered as a business model for creating, providing and preserving value for customers.

Economic forensic examination is a means of achieving a better balance of errors of the first and second kind in law enforcement, but in itself depends on the incentives and capabilities of judges to assess the sufficiency of the grounds for its appointment. The purpose of any forensic examination is to obtain by the court, for the purposes of the administration of justice, special knowledge and information about a particular fact or phenomenon that is beyond the limits of legal science. It is antimonopoly legislation and law enforcement that can most clearly illustrate the fusion of legal and economic disciplines, where legal norms frame economic reality, forming a procedural contour for the court. The Court thus becomes the receiver of the standards of economic science, its approaches and rules. At the same time, it is shown that in reality the courts are faced with a difficult dilemma, on the one hand, compliance with procedural purity and, on the other hand, obtaining the necessary to improve the balance of errors of the first and second kind of economic evidence in terms of market research, determining the position of the economic entity that is the object of law enforcement, as well as the qualification of actions with the use of relevant theory of harm. The assessment of economic evidence by the courts should be based on a competent independent expert assessment and proceed from the categories of necessity and sufficiency. A set of imperfect substitutes for the assessment by the court of economic evidence on the merits is indicated. The article offers simple and practical approaches to the investigation by courts of economic facts and circumstances in order to make a correct, complete and reasoned decision on the antimonopoly case.
Theoretical and Methodological Content of the Concept “Competitive Advantage”
Authors:   Synergy University, Kovalenko Alexander I.
Published: May 2022

The purpose of this article is to compare certain theoretical concepts that are developing today in the field of competitive management: the strategic architecture (by V. Kvint) and constructive theory of competition (by Yu. Rubin) with the concept of competitive advantage (by M. Porter). As part of the scientific discussion, the authors answer questions about the place of competitive advantage in the strategic management system, the essence of competitive advantage, and the sustainability of competitive advantage. To do this, we review and analyze the systems of views of the above scientists in the cited sources. Different approaches to understanding and using the term “competitive advantage” are considered in the work as different research programs, the contradiction of which to each other does not require the rejection of an older concept. At its core, competitive advantage is understood as the content of a strategic decision, a strategic task, a system for its implementation, and its manifestation in the results of competitive activity. Two different directions of competitive advantage management are distinguished in the work: creation/ formation (positive side) and protection / providing sustainability (negative side) of competitive advantage. Value chain (M. Porter) and transient advantage (R. McGrath) tools can be called as the positive side of competitive advantage. The negative side of competitive advantage can be considered in certain types of economic moats. The ideas of economic moat and transient advantage respond differently to the question of sustainability of competitive advantage. The paper substantiates the conclusion that both in the theory of strategic architecture (Kvint) and in the constructive theory of competition (Rubin), the term “competitive advantage” is used in completely different meanings, which are complex interpretations of the original meaning.

A note on extended Arimoto's entropies
Authors: de Wet T. , Österreicher F.
Published: May 2022

Arimoto (1971) introduced, among other things, a class of entropies for probability distributions on any finite set of elements, which includes Shannon’s entropy (1948) as a special case. Restricted to the set P 2 of probability distributions P = ( t , 1 − t ) on a set with only two elements his class of entropies is given in terms of h α ( t ) =    1 1 − α [ 1 − ( t 1 / α +( 1 − t ) 1 / α ) α ] if α ∈ ( 0 , ∞ ) \{ 1 } − [ t ln t +( 1 − t ) ln ( 1 − t )] if α = 1 min ( t , 1 − t ) if α = 0 . As Vajda (2009) extended a certain class of Csiszár’s f -divergences, which are closely related to Arimoto’s entropies to all parameters α ∈ R , the authors of this note generalised the special case of Arimoto’s entropies for probability distributions P ∈ P 2 to all α ∈ R (De Wet and Österreicher, 2016). It turns out that these entropies are given for negative α = − k , k ∈ ( 0 , ∞ ) , by h − k ( t ) = 1 1 + k t ( 1 − t ) [ t 1 / k +( 1 − t ) 1 / k ] k , t ∈ [ 0 , 1 ] . In the present note their extension to probability distributions P ∈ P n for n ≥ 2 is investigated. In addition, a comparison of Arimoto’s extended class of entropies with Rényi’s and Tsallis’ classes, is given. For the axiomatic characterization of the latter two classes of entropies we refer to the survey paper by Csiszár (2008). Keywords: Dissimilarity measure (f-divergence), Measure of information (entropy)
Combining the Box-Cox power and generalised log transformations to accommodate nonpositive responses in linear and mixed-effects linear models
Authors: Hawkins D. M. , Weisberg S.
Published: May 2022

Transformation of a response variable can greatly expand the class of problems for which the linear regression model or linear mixed-model is appropriate. Beginning with the fundamental work of Box and Cox, maximum-likelihood-like estimation has been applied to select a transformation from among a family of transformations, with the possible goals of achieving approximate normality, removing nonlinearity in a mean function, or stabilizing variance. The Box-Cox power family (BC) of transformations is by far the most common with the Box-Cox methodology, and it requires a strictly positive response. In this article we introduce a new family of transformations that we call the Box-Cox power with nonpositives (BCN) family that allows inclusion of a few nonpositive values. The BCN family is a modification of the basic power family that is inspired by the generalised log, or glog transformation, proposed for use with the more limited goals of stabilizing variance or achieving approximate normality. The glog transformation is itself a special case of the Johnson SU transformation, and we show that the BCN family derived from it is in turn a simple modification of the BC family. Computer code for implementing this family is included in the car package in R (Fox and Weisberg, 2011). The methodology is illustrated using a problem in clinical chemistry.

New results from a beta-Pareto class
Authors: Makgai S. L. , Bekker A. , Ferreira J. T. , Arashi M.
Published: May 2022

In this paper, we propose new results on a beta-Pareto class. This extension evolved by using newly proposed class of beta distributions as generator distributions (F(x)) within the generator-parent approach: H(x) = F(G(x)) with G(x) the Pareto distribution as the parent distribution. Fundamental properties are studied, including moments and Rényi entropy. We illustrate the added value to the literature with a numerical example using hydrology data, indicating that this newly proposed class is a valid candidate to consider in modelling within the hydrology arena. Keywords: Generalised beta type, Generator distribution, Kolmogorov-Smirnov measure, Parent distribution, Pareto

Published: May 2022

Maintaining the Quality-of-Service (QoS) of Voice-over-Internet Protocol (VoIP) is a major problem due to the instability of network conditions. One factor that influences VoIP call quality is the employed codec. In this research, the influence of codec on the QoS of VoIP calls is evaluated under Wi-Fi, 2G, 3G and 4G networks. VoIP calls are established using PCMA, PCMU, GSM and G.722 codecs and QoS parameters including jitter, round trip time and packet loss are measured. QoS measurements are compared against considered networks and codecs. Results illustrate that there exists a codec that better suits each network with considerable advantages over other codecs and minimum drawbacks.

Published: May 2022

Sustainable development goals have gotten acute attention from researchers in the latest decades. Cultural matters are evident for sustainable development, but scientifically incorporating the importance of cultural dimensions remains a challenge. The purpose of the study is to find a link between cultural dimensions and sustainability goals. This study aims to use a compound cultural index to extend the CCI, by including the latest research results and sug-gesting a CCI covering six cultural dimensions identified in Hofstede’s cultural model. H. Yeganeh, 2011, proposed the methodology for constructing a composite cultural index, but the author included only several cultural dimensions in CCI. The authors of this paper present the analysis of fifteen sustainable development goals (SDG) in the 27 European Union countries aiming to rank countries according to the contribution of national culture to sustainable development goals. The methodology was used for panel analysis and the constructed correlation matrix performed by the authors. The finding results prove a correlation exists with four sustainable development goals, although the direction differs–one has a positive link and three–negative one. Value of the paper – the authors created a compound cultural index CCI for sustainable development studies and extended the results delivered by other authors.

Authors: Jasińska-Biliczak Anna
Published: May 2022

The purpose of presented research was to identify the new trends in entrepreneurship which occurs in start-ups (STPS) such as endogenous development based at the sustainable development (SD). It is shown as the conscious-ness of actual economy trends as well as the enterprise’s needs, especially at the very early stage of development based at the SD concept. There is presented the SD understood as the consumption of resources which allows them to be preserved for future generations. The scientific problem is to examine if there is the real impact of the SD concept at the STPS practice. This research goal is to build a future, strong STPS based at the durable, scientifically proved, economic concept. The proposed methodology, to achieve its aim, consists of three stages: desk research, deepened interview and primary data analysis. Such a methodology approach lets to observe the change in the new enterprises grow up, espe-cially at the STPS group. The findings shows that the SD concept is more and more often the base of their development strategy and that STPS, which based their development at SD, are characterized by the higher survival rate. The results of presented research allow to develop the economy knowledge about both: the STPS development and SD practical implication into entrepreneurship. Especially the originality of the research is pointing the connection between STPS survival rate and their successful development and its strategy based at the SD concept. As it may be limited by the specificity of the pandemic, when it took place, it may have practical implication into STPS development concepts and strategies.

mini-Neptune in a 7.7 day period orbit. HIP 94235 is part of the AB Doradus moving group, one of the youngest and closest associations. Due to its youth, the host star exhibits significant photometric spot modulation, lithium absorption, and X-ray emission. Three 0.06% transits were observed during Sector 27 of the TESS Extended Mission, though these transit signals are dwarfed by the 2% peak-to-peak photometric variability exhibited by the host star. Follow-up observations with the Characterising Exoplanet Satellite confirmed the transit signal and prevented the erosion of the transit ephemeris. HIP 94235 is part of a 50 au G-M binary system. We make use of diffraction limited observations spanning 11 yr, and astrometric accelerations from Hipparcos and Gaia, to constrain the orbit of HIP 94235 B. HIP 94235 is one of the tightest stellar binaries to host an inner planet. As part of a growing sample of bright, young planet systems, HIP 94235 b is ideal for follow-up transit observations, such as those that investigate the evaporative processes driven by high-energy radiation that may sculpt the valleys and deserts in the Neptune population.
Tracking Movement of Long-lived Equatorial Coronal Holes from Analysis of Long-term McIntosh Archive Data

Published: May 2022

Features at the Sun’s surface and atmosphere are constantly changing due to its magnetic field. The McIntosh Archive provides a long-term (45 yr) record of these features, digitized from hand-drawn synoptic maps by Patrick McIntosh. Utilizing this data, we create stack plots for coronal holes, i.e., Hovmöller-type plots of latitude bands, for all longitudes, stacked in time, allowing tracking of coronal hole movement. Using a newly developed two-step method of centroid calculation, which includes a Fourier descriptor to represent a coronal hole’s boundary and calculate the centroid by the use of Green’s theorem, we calculate the centroids of 31 unique, long-lived equatorial coronal holes for successive Carrington rotations during the entire solar cycle 23, and estimate their slopes (time versus longitude) as the coronal holes evolve. We compute coronal hole centroid drift speeds from these slopes, and find an eastward (prograde) pattern that is actually retrograde with respect to the local differential rotation. By discussing the plausible physical mechanisms which could cause these long-lived equatorial coronal holes to drift retrograde, we identify either classical or magnetically modified westward-propagating solar Rossby waves, with a speed of a few tens to a few hundreds of meters per second, to be the best candidate for governing the drift of deep-rooted, long-lived equatorial coronal holes. To explore plausible physics of why long-lived equatorial coronal holes appear few in number during solar minimum/early rising phase more statistics are required, which will be studied in future.

Background: The Coronavirus Disease 2019 (COVID-19) has caused many lifestyle changes, especially in the diet. Policies such as physical distancing and quarantine orders aimed to mitigate to spread of COVID-19 have affected the economy and, therefore, the dietary habits of the people. 
Aim: The purpose of this study was to analyze the associations between income levels and dietary habits during the COVID-19 pandemic. 
Methods: This cross-sectional study included 697 Indonesian adults from various regions in Indonesia. The study was conducted from June - August 2020. Data were obtained through a self-administered online questionnaire including dietary habits, lifestyles, and quality of life data adapted from MyNutriLifeCOVID-19 Online Survey. To analyze the associations between income levels and dietary habits during the COVID-19 pandemic, a chi square test was used. Data were analyzed using SPSS version 20.  
Results: Respondents had mean age of 27.56 ± 8.58 years and the majority were women (83.6%). The percentage of people with large-scale social restrictions was 47.5%. Respondents reported that their dietary habits were healthier during the pandemic (46.2%), with the majority categorized as high and very high-income status (59.1%). From self-reported of the people in Indonesia, there was association between high-income level and self-perceived healthier dietary habits. Higher-income level was also associated with higher frequency of online food/drink delivery, consuming western diet foods, consuming dietary supplements, and probiotic consumption (p<0.05). 
Conclusions: The self-reported that during the COVID-19 pandemic, the dietary habits of people with a higher income level had healthier compared to their dietary habits before the pandemic. However, it is also related to higher energy, cholesterol, and saturated fat intakes due to consuming high western diet foods.  Social inequalities in dietary intake should be considered through promoting a healthy balanced diet with affordable price and healthy food processing in the community.

Published: May 2022

BACKGROUND: Fruit and vegetable consumption among preschool children in Indonesia is lower than recommendations, which may be due to types of food availability at home and unhealthy feeding practices such as restriction and parent pressure. Providing nutrition education through booklets and counseling on healthy food (fruit and vegetable) consumption can help to provide information to parent’s thus resulting healthy behavior, compared to merely providing booklets without counseling.

AIM: The aim of this study is to determine the effect of nutrition education using booklets with counseling versus without counseling on home food availability and parent feeding practices in preschool children.

METHODS: A quasi-experimental study utilized a pre-test and post-test design with a control group. Sampling methods included both purposive sampling and simple random sampling. Purposive sampling was used to select Danurejan district as the sub-district with the highest obesity percentage in Yogyakarta Municipality. Meanwhile, simple random sampling was applied to select children and schools (Early Childhood Education Program Pendidikan Anak Usia Dini [PAUD] or kindergartens Taman Kanak-kanak [TK]). There were 56 people (28 intervention and 28 controls) taken from 4 PAUD/TK. The intervention group received nutrition education using booklets as well as one 30–60 min counseling session carried out at the participant’s home. The control group was provided with booklets, but did not receive counseling. The pre-test was carried out before nutrition education was given, and the post-test was conducted 30 days after the nutrition education. Fruit and vegetable availability at home were assessed using questionnaire, and parent feeding practices were assessed using the Comprehensive Food Feeding Questionnaire. The statistical tests used to assess outcomes between groups included pair t-test, Wilcoxon, Mann–Whitney, and independent t-test.

RESULTS: There were increase in healthy eating guidance and monitoring before and after nutrition education was provided in the intervention group (p = 0.00; p < 0.05), but no differences were found in restriction, child control, and parent pressure (p = 0.11, p = 0.48, p = 0.28; p ≥ 0.05). There was a decrease in child control behavior before and after nutrition education in the control group (p = 0.00; p < 0.05), but there were no differences in healthy eating guidance, monitoring, restriction, and parent pressure (p = 0.17, p = 0.18, p = 0.53, 0.62; p ≥ 0.05).

CONCLUSIONS: Results demonstrate that using counseling in addition to nutrition education booklets can increase mother’s implementation use of healthy eating guidance and monitoring, with the potential to promote healthy weight within families.
Mezile’s Model (Back Massage and Self-Hypnosis) Based on Information and Technology to Lose the Anxiety of Postpartum Mothers in COVID-19 Pandemic Era
Authors: Widyawati Melyana , Nazilah Rohmatun , Latifah Leny
Published: May 2022

BACKGROUND: The roles of husbands to keep the psychological condition of pregnant and postpartum mothers are low. Many husbands could not perform full attention and support during the pregnancy, delivery, and postpartum period. Heretofore, the researchers do not find studies that include the roles of the husband from antenatal until postnatal care during the COVID-19 pandemic.

AIM: This research aims to create Mezile’s model in the form of back massage and self-hypnosis based on information and technology with adequate design and effective implementation to lose the anxiety of postpartum mothers. This model also involved husbands taking the role from the antenatal until postnatal care.

METHODS: This research and development used a true experimental design with pre- and post-test control group design. The researchers used simple random sampling. The subjects consisted of 50 participants in the experimental group and 50 participants in the control group. The experimental group received the intervention with self-hypnosis training, while the husbands of the experimental group received back massage training. The husbands in the control group received only back massage training. The intervention lasted from the 2nd until the 15th day after normal delivery. Then, mothers with post-section cesarean received the training on the 8th until the 21st day. The researchers used Wilcoxon and Mann–Whitney tests.

RESULTS: Mezile’s model refers to back massage and self-hypnosis based on information and technology. It was reliable as the holistic-based education media to apply effective management to lose anxiety (p = 0.03), higher than the control group.

CONCLUSION: Mezile’s model, back massage, and self-hypnosis, based on information and technology, are reliable for obstetric care education based on holistic nature during pregnancy and postpartum. The implementation was effective in managing the anxiety of postpartum mothers in the control group.
Les liens entre adaptation et atténuation : quand s’adapter aggrave le changement climatique
Authors: Viguié Vincent
Published: May 2022

Si, au premier abord, l’« adaptation » au changement climatique et l’« atténuation » du changement climatique sont deux sujets relativement distincts, ils ne sont pas en pratique indépendants. Ils mobilisent en effet souvent les mêmes outils de politique publique, et se contraignent l’un l’autre. Notamment, certains choix d’adaptation peuvent mener à des consommations massives d’énergie (généralisation de la climatisation, dessalement de l’eau de mer…). Cela fait courir le risque d’un cercle vicieux dans lequel le changement climatique contribue lui-même à la hausse des émissions. Privilégier le déploiement d’autres stratégies, même si ce n’est pas toujours simple, est dès lors essentiel. Au-delà de l’atténuation, des questions similaires se posent avec d’autres enjeux sociaux ou environnementaux, et éviter le risque de conséquences involontairement néfastes associées à certains choix d’adaptation est un des enjeux cruciaux des années à venir.

The Influence of Immersive Virtual Reality (IVR) on Skill Transfer of Learners: The Moderating Effects of Learning Engagement
Authors: Yang Peng , Liu Zhi
Published: May 2022

Immersive virtual reality (IVR) is a full integration of virtual simulation and reality through computer engines and digital technologies. In particular, upon entering the field of education, IVR triggers the comprehensive reform of the education industry, realizes the interaction between virtual and real worlds, shapes a more highly immersive teaching scene, and meets the personalized needs of different learners. Thus, exploring the transfer of learning skills under IVR and traditional teaching modes is of great significance to understanding their causal relationship. Results show that training methods have significant differences in post-test scores. Immersive virtual experimental teaching plays a significant role in the skills transfer of learners, and learning engagement has a significant moderating effect in the above relationship. In this study, the results have important reference value for enriching the design of immersive teaching content, improving its design of translation, and promoting the skills transfer of learners to higher-order thinking knowledge.

Computational Thinking (CT) is very useful in the process of solving everyday problems for undergraduates. In terms of content, computational thinking involves solving problems, studying data patterns, deconstructing problems using algorithms and procedures, doing simulations, computer modeling, and reasoning about abstract things. However, there is a lack of studies dealing with it and its skills that can be developed and utilized in the field of information and technology used in learning and teaching. The descriptive research method was used, and a test research tool was prepared to measure the level of (CT) consisting of (24) items of the type of multiple-choice to measure the level of "CT". The research study group consists of (100) third-year students studying at the University of Baghdad in Computer Science within the scope of (2020-2021). The results are detailed.

Authors: Hameed Shaker Shaimaa , Al-Khalidi Farah Q.
Published: May 2022

The main target of the work in this paper is to detect the gender and oldness of a person with an accurate decision and efficient time based on the number of facial outward attributes extracted using Linear-Discriminate Analysis to classify a person within a certain category according to his(her) gender and age. This work was deal with color facial images via the Iterative Dichotomiser3 algorithm as a classifier to detect the oldness of a person after gender detected. This paper used the Face-Gesture-Recognition-Research-Network aging dataset. All facial images in the dataset were categorizing into binary categories using k-means. This is followed by the process of dividing all samples according to age classes that belonging to each specific sex category. Thus, this division process enabled us to reach a quick and accurate decision.  The results showed that the accuracy of the proposal was 90.93%,  and F-measure was 89.4.

Malaria remains one of the essential public health problems in Indonesia. The year 2015 was originally set as the elimination target in Java Island, but there are still several regencies on Java reporting malaria cases. Spatial technology helps determine local variations in malaria transmission, control risk areas and assess the outcome of interventions. Information on distribution patterns of malaria at the sub-district level, presented as spatial, temporal, and spatiotemporal data, is vital in planning control interventions. Information on malaria transmission at the sub-district level in three regencies in Java (Banyumas, Kebumen, and Purbalingga) was collected from the Agency for Regional Development (Bappeda), the Population and Civil Registration Agency (Disdukcapil) and Statistics Indonesia (BPS). Global spatial autocorrelation and space-time clustering was investigated together with purely spatial and purely temporal analyses using geographical information systems (GIS) by ArcGis 10.2 and SaTScan 8.0 to detect areas at high risk of malaria. Our results show that malaria was spatially clustered in the study area in central Java, in particular in the Banyumas and Purbalingga regencies. The temporal analysis revealed that malaria clusters predominantly appeared in the period January-April. The results of the spatiotemporal analysis showed that there was one most likely malaria cluster and three secondary clusters in southern central Java. The most likely cluster was located in Purbalingga Regency covering one sub-district and remaining from the beginning of 2016 to the end of 2018. The approach used can assist the setting of resource priorities to control and eliminate malaria.

Background: We investigated whether fasting glucose (FG) variability could predict the risk of dementia.Methods: This cohort study analyzed data from Koreans with diabetes after at least three health examinations by the Korean National Health Insurance Corporation between 2005 and 2010, which included at least one examination between 2009 and 2010. A total of 769,554 individuals were included, excluding those aged <40 years and those with dementia. FG variability was measured using the variability independent of the mean (FG-VIM). The incidence of dementia was defined by the International Classification of Diseases 10th Revision codes and prescription of anti-dementia medication and was subdivided into Alzheimer’s disease (AD) and vascular dementia (VD).Results: During the 6.9-year follow-up, 54,837, 41,032, and 6,892 cases of all-cause dementia, AD, and VD, respectively, were identified. Cox proportional regression analyses showed that as the FG-VIM quartile increased, the risk of dementia serially increased after adjustment for metabolic factors, income status, and diabetes-related characteristics, including the mean FG. Participants in FG-VIM quartile 4 showed a 18%, 19%, and 17% higher risk for all-cause dementia, AD, and VD, respectively, than those in quartile 1; this particularly included non-obese patients with a longer duration of diabetes, high FG levels, dyslipidemia, and those taking glucose-lowering medications. Conversely, the baseline FG status and dementia showed a U-shaped association.Conclusion: Increased FG variability over 5 years can predict the risk of dementia in individuals with diabetes in Korea. This finding was more pronounced in patients with less favorable metabolic profiles.

Published: May 2022

Plica polonica is a rare condition presenting as a mass of scalp hair with irregular twists and irreversibly entangled plaits, which are firm to hard impenetrable mass of keratin cemented together with dirt and exudates. The exact etiopathogenesis of plica neuropathica is not known, but it can be due to longitudinal splitting or weathering of hair shaft due to vigorous friction and frequent use of harsh shampoos and cleansers or long hair with poor hair care Drug-induced hair matting due to chemotherapeutic drugs and due to neurotic illness like hysteria, anxiety, to psychotic illness have also been reported. Dermatoscopy showed interwining of hair shaft with matting and honey-colored concretions mimicking “wrangled mesh of wires” appearance. The treatment of plica neuropathica involves cutting the matted hair and evaluating underlying psychiatric illness to prevent recurrence.
All that a Dermatotrichologist needs to know about Hair Camouflage

Published: May 2022

Hair loss can impact a person's quality of life in ways incomprehensible. People value hair for different reasons, but value it nonetheless. There is a myriad of conditions that impede hair growth or cause hair to grow in an unattractive manner such as androgenetic alopecia, alopecia areata, and chemotherapy-induced hair loss. For conditions like cicatricial alopecia, there are hardly any options available once permanent loss of hair sets in. The role of hair transplantation too is limited in such cases where the donor area has been compromised. Thus, addressing the concern of hair loss and presenting all possible options available even after medical and surgical options flounder due to their limitations is a responsibility every dermatotrichologist carries and a plethora of camouflage options are available to improve the appearance of hair right from hairpieces to more permanent methods like scalp micropigmentation.
Higher transgressions of the Pfaffian
Authors: Moroianu Sergiu
Published: May 2022

We define transgressions of arbitrary order, with respect to families of unit-vector fields indexed by a polytope, for the Pfaffian of metric connections for semi-Riemannian metrics on vector bundles. We apply this formula to compute the Euler characteristic of a Riemannian polyhedral manifold, very much in the spirit of Chern’s differential-geometric proof of the generalized Gauss–Bonnet formula on closed manifolds and on manifolds-with-boundary. As a consequence, we derive an identity for spherical and hyperbolic polyhedra linking the volumes of faces of even codimension and the measures of outer angles.
