Advanced Deep-Plane Rhytidectomy: Advantages for Neck Treatment and Volumization of the Midface.

The aged neck is the most common motivator for patients seeking facial rejuvenation. Unlike the deflated midface, surgical treatment is still the gold standard for optimal outcomes. It is our view that the majority etiology of both the aged neck and deflated midface is gravity's effects on the superficial soft tissue envelope, leading to soft tissue redundancy. It is also our view that the deep-plane rhytidectomy is supported by anatomy, embryology, and clinical evidence as the best methodology to treat soft tissue redundancy without producing the aesthetic and longevity issues associated with superficial musculoaponeurotic system techniques. As one of the early pioneers in deep-plane rhytidectomy, the lead author will define contemporary advances in deep-plane technique such as dissection entry point, flap design, and flap fixation concepts that allow aggressive approach to treating both the aged neck and deflated midface.

Study on Spatial Scale Selection Problem: Taking Port Spatial Expression as Example

Spatial scale is a key factor, which affects the accuracy of spatial expression and further influences the spatial planning of a research area. In order to help improve the efficiency and accuracy of optimal scale selection for all sizes of research areas, a universal two-layer theoretical framework for optimal scale selection was proposed in this paper. Port area was taken as an example to systematically clarify the application of the proposed framework, and the scale selection model for port spatial expression was established. Least-squares-based mean change point analysis was introduced into the model, and the concept of a comprehensive change point was proposed to form the criterion for optimal port scale selection. First, an appropriate scale domain was preliminarily determined by the upper scale selection model. Then, the lower scale selection model determined the final appropriate scale domain and took the corresponding scale of a minimum comprehensive change point as the final optimal scale for port spatial expression. Finally, a port area in Qingdao in eastern China was taken to verify the feasibility of the proposed model, and the optimal scale was suggested to be 14 m. The proposed framework in this paper helps ensure the accuracy of spatial expression and reduce spatial data redundancy, and it can provide the methodological references for planners to better spatialize a research area, which will guarantee the subsequent spatial planning work.

Transverse Quantum Superfluids

Even when ideal solids are insulating, their states with crystallographic defects may have superfluid properties. It became clear recently that edge dislocations in 4He featuring a combination of microscopic quantum roughness and superfluidity of their cores may represent a new paradigmatic class of quasi-one-dimensional superfluids. The new state of matter, termed transverse quantum fluid (TQF), is found in a variety of physical setups. The key ingredient defining the class of TQF systems is infinite compressibility, which is responsible for all other unusual properties such as the quadratic spectrum of normal modes (or even the absence of sharp quasiparticles), irrelevance of the Landau criterion, off-diagonal long-range order at T = 0, and the exponential dependence of the phase slip probability on the inverse flow velocity. From a conceptual point of view, the TQF state is a striking demonstration of the conditional character of many dogmas associated with superfluidity, including the necessity of elementary excitations, in general, and the ones obeying Landau criterion in particular.

Study on the sorption and desorption behavior of La3+ and Bi3+ by bis(2-ethylhexyl)phosphate modified activated carbon.

The separation of 213Bi from its parent radionuclide 225Ac via radionuclide generators has proven to be a challenge due to the limited performance of the current sorbents. This study evaluated the separation performance of La3+ (as a surrogate for 225Ac) and Bi3+ using bis(2-ethylhexyl)phosphate monofunctionalized activated carbon (HDEHP/AC). The potential applications of phosphate groups as active sites and the carbon structure as a sorbent support were confirmed and validated. Various factors, including pH values, salt concentration, halide ions, contact time, solid-to-liquid ratio, initial La3+/Bi3+ concentration, and gamma irradiation were examined through batch sorption experiments in both single and binary systems. HDEHP/AC had a high sorption capacity for La3+ via electrostatic attraction, with the sorption data fitting well to the pseudo-second-order kinetic equation and Langmuir model. The sorption performance of La3+ on HDEHP/AC was minimally affected as the NaCl/NaI concentrations increased at pH = 2, whereas the sorption capacity for Bi3+ decreased significantly. Additionally, selective desorption of La3+ and Bi3+ was achieved using HNO3 and NaI solutions, respectively. These results backed up by a conceptual separation process point toward a potential use of these materials in a direct/inverse 225Ac/213Bi radionuclide generator. Further optimization of the material and separation process will be required to bring this class of promising materials into an actual generator for medical applications.

Control Method For Processes in a Horizontal Organization and its Relationship with Business Success Aligned with the Sustainable Development Goals (SDG)

Objective: This study aims to develop an appropriate control method for a horizontal organization that is managed by processes, based on the establishment of the functioning of this type of organizations from a theoretical conceptual point of view and in application of the mathematical method to find an appropriate equation. Methodology: In this research, the descriptive and analytical approach was used, both to understand the functioning of the processes of the horizontal organization and to infer the relationship between the fulfillment of the objectives of the different types of processes, assigning a specific weight to each one according to its relative impact on the mission and formulating the equations whose development converged in the proposed control method. Results: The results show that this method not only provides an effective quantitative tool for strategic decision making, but also faithfully reflects the collaborative and decentralized nature of horizontal organizations. The practical application of the equation will allow managers to prioritize the most critical processes and align actions with strategic objectives and mission. Conclusions: The development of the work confirmed the possibility of generating a control method for a horizontal organization based on the evaluation of its processes, thus becoming a decision-making tool that ensures organizational success, a necessary condition for having efficient business structures that support the growth of society aligned with the Sustainable Development Goals (SDG).

Becoming displaceable, feeling displacing, un/doing displacement – Conceptualizing urban residential displacements as dissimilar experiences amidst the global housing affordability crisis

ABSTRACT Urban residential displacement (URD) displays its expansive character globally in the current housing affordability crisis, reinforcing both violent and more subtle, everyday-life-related dynamics. Yet, a comprehensive theorization of variegated forms of crisis-generated URD as witnessed in the Global North remains underdeveloped. To address URD more broadly, I propose a distinct reading around the concepts of “becoming displaceable”, “feeling displacing”, and “un/doing displacement”. These three conceptual entry points constitute the political-economic, cognitive-affective, and socio-spatial dimensions of URD. The triad allows us to study the relational spatio-temporal dynamics that displacees perceive and experience enforced by power relations related to housing economies. This nuanced, praxeologically, and Deleuze-inspired perspective further contributes to an advanced understanding of the emergence of classed, racialised/ethnicised, and gendered URD processes. The interaction of the three pillars opens up different rooms for manoeuver dealing with and navigating through URDs, ultimately diversifying them. Furthermore, it allows us to understand the processual and non-linear unfolding of URD and relate dissimilar forms to each other.

New Poland in the New World

Abstract This paper discusses the project of creating a Polish colony in the United States, propagated by Józef Alfons Potrykowski and a group of his followers. In 1843–1853, seeing no possibility of preserving Polishness in Europe, they strove to establish a New Poland (Nowa Polska) in North America or Australia. Initially it was to be a single colony, but Potrykowski’s blueprint projected its development and the creation of an entire Polish province that would eventually join the United States as an autonomous state. In propounding such solutions, Potrykowski was under the tangible influence of the early socialists, and for this reason he stressed the necessity of building the colony upon such principles as equality and brotherhood. From a conceptual point of view, his project was based on categories of both a universal and particular character, with such paired (counter)concepts as sacrifice-treason, or brotherhood-egoism coming to the fore. Whilst Potrykowski’s plans bore scant fruit in terms of their practical realisation, they nevertheless offer valuable insights into East Central European utopianism in the mid-nineteenth century.

Study of Topological Spaces that Don’t Rely on Points as their Basis

Traditionally, the concept of points and neighborhood structures has been quite dominant in defining and further analyzing various properties in the study of topological spaces. In pointless topology-or point-free topology, also referred to as locale theory-the key emphasis is shifted from points to lattices of open sets. In addition to gaining further insight into spatial properties, this approach has important implications in fields like theoretical computer science, logic, and categorical theory. It is the purpose of the present work to be mainly interested in issues of the foundation of point-free topology: locales, frames, mutual relationships between them; the ways of interpreting classical topological concepts in the new language and the strong and weak points of such a point-free view. In the process, we focus on some of the significant applications of point-free topology, both within mathematics and beyond. The present paper is an attempt to give a broad overview of pointfree topology, discussing both its theoretical basis and its practical significance.

Mobilizing strategic inflection points for sustainment of an effective intervention in an integrated learning health system: an interpretive description

BackgroundInnovative models of care have the potential to improve the sustainability of health systems by improving patient and provider experiences and population outcomes while simultaneously reducing costs. Yet, it is challenging to recognize the distinctive points during research and quality improvement processes that contribute to sustainment of effective interventions. The business concept of an inflection point—the position on the curve of a trajectory where the progress in implementation of an intervention is accelerated or decelerated—may be useful to understand implementation and improve sustainability and ultimately sustainment of effective interventions. The purpose of this study was to retrospectively identify and describe strategic inflection points that accelerated the sustainability process and led to the sustainment of Alberta Family Integrated Care.MethodsThis qualitative study was conducted in Alberta, Canada and employed an interpretive description design. Purposively sampled documents (proposals, project management plans, reports to funders and sponsors, meeting minutes, and fidelity audit and feedback checklists) from the Alberta Family Integrated Care cluster randomized controlled trial and quality improvement project constituted data for this study.ResultsTo accelerate sustainability in the research context, we identified (1) alignment with strategic priorities, (2) iterative, user-centered co-design, and (3) contextualization of implementation as strategic inflection points. To accelerate sustainability in the health system context, we identified (1) the learning health system, (2) enduring partnerships, (3) responsivity to societal and system change, (4) embedded governance, and (5) intentional integration into the health system as strategic inflection points. Capitalizing on these strategic inflection points led to sustainment of Alberta Family Integrated Care in the provincial health system.ConclusionsWe identified key inflection points in the research and health system contexts that led to sustainment of Alberta Family Integrated Care. By anticipating, recognizing, and leveraging inflection points in the sustainability process, researchers may be able to accelerate implementation and achieve sustainment of multi-component interventions in complex systems.Trial registrationClinicalTrials.gov: NCT02879799.

On Soft Topological Groups and Soft Function Spaces

In this paper, the definition of a soft topological group based on the concept of soft points is introduced. Let [Formula: see text] denote the collection of all soft continuous functions between soft topological spaces [Formula: see text] and [Formula: see text]. We investigate the structures of abstract groups, and soft groups within the context of the soft function space. Furthermore, the soft topological group structure of the group [Formula: see text] under soft topologies is explored.

Interpretable Support Vector Machine and Its Application to Rehabilitation Assessment

This paper does present an interpretable support vector machine (SVM) and its application to rehabilitation assessment. We introduce the concept of nearest boundary point to standardize the one-class SVM decision function and determine the shortest path for data from abnormal cases to become those from normal cases. This analytical approach is computationally simple and provides a unique solution. The nearest boundary point of abnormal data can also be used to analyze the cause of abnormal classification and indicate countermeasures for normalization. These properties render the proposed interpretable SVM valuable for medical assessment applications and other problems that require careful consideration of classification results for treatment. Simulation and application results demonstrate the feasibility and effectiveness of the proposed method.

Zero-Dimensional Shimura Varieties and Central Derivatives of Eisenstein Series

Abstract We formulate and prove a version of the arithmetic Siegel–Weil formula for (zero dimensional) Shimura varieties attached to tori, equipped with some additional data. More precisely, we define a family of “special” divisors in terms of Green functions at archimedean and non-archimedean places and prove that their degrees coincide with the Fourier coefficients of the central derivative of an Eisenstein series. The proof relies on the usual Siegel–Weil formula to provide a direct link between both sides of the identity, and in some sense, offers a more conceptual point of view on prior results in the literature.

Exploring the control of whole-body angular momentum in young and elderly based on the virtual pivot point concept.

While walking, ground reaction forces point from the centre of pressure to the neighbourhood of a focal point, namely the virtual pivot point (VPP), that adjusts angular momentum around the centre of mass (CoM). This study explores how age and speed affect the VPP quality and position during walking. Analysing an experimental dataset reveals high quality of the VPP in the sagittal plane for both young and elderly groups, regardless of speed. However, in the frontal plane, the VPP quality decreases with increasing speed, with elderly participants exhibiting significantly lower quality. Although not a direct measure of balance, VPP quality reflects changes in whole-body angular momentum owing to ageing and speed. Additionally, a template model is used to reproduce the VPP quality and position trends observed in the experiment. Simulation results highlight the sensitivity of VPP quality to leg force feedback and show that changing VPP height has minimal effect on gait speed. Furthermore, energy redistribution occurs through increased hip extension and leg damping, associated with a greater horizontal VPP distance from the CoM, observed in elderly walking. This study shows promise for analysing gait based on VPP, potentially aiding clinical interventions and supporting locomotion in the elderly.

볼록 육각형의 나폴레옹의 정리 확장에 대한 연구

This study was based on the research results conducted as a R&E project for the gifted students with a financial support from the Korea Foundation for the Advancement of Science and Creativity. In this study, the Napoleon hexagon ofhexagons was explored by expanding the Fermat-Torricelli point defined in a triangle and the Napoleon triangle into a convex hexagon. The results of this study are as follows. First, the equivalence condition for convex hexagons in which the Napoleon hexagon exists was discovered. Second, the area formula for Napoleon’s hexagon was shown. Third, we found various regular hexagons related to the Napoleon-containing hexagon and found that the centers of each regular hexagon were identical. Through this study, the concepts of the Fermat-Torricelli point and Napoleon triangle of triangles were expanded to convex hexagons, and it is expected that the expansion of mathematical concepts willcontribute to the development of mathematics. In addition, it is expected that additional research will be conducted in the future by exploring attractive regular hexagons whose centers coincide with the searched hexagons including Napoleon.

Analysis of a Class of Minimization Problems Lacking Lower Semicontinuity

The minimization of nonlower semicontinuous functions is a difficult topic that has been minimally studied. Among such functions is a Heaviside composite function that is the composition of a Heaviside function with a possibly nonsmooth multivariate function. Unifying a statistical estimation problem with hierarchical selection of variables and a sample average approximation of composite chance constrained stochastic programs, a Heaviside composite optimization problem is one whose objective and constraints are defined by sums of possibly nonlinear multiples of such composite functions. Via a pulled-out formulation, a pseudostationarity concept for a feasible point was introduced in an earlier work as a necessary condition for a local minimizer of a Heaviside composite optimization problem. The present paper extends this previous study in several directions: (a) showing that pseudostationarity is implied by (and thus, weaker than) a sharper subdifferential-based stationarity condition that we term epistationarity; (b) introducing a set-theoretic sufficient condition, which we term a local convexity-like property, under which an epistationary point of a possibly nonlower semicontinuous optimization problem is a local minimizer; (c) providing several classes of Heaviside composite functions satisfying this local convexity-like property; (d) extending the epigraphical formulation of a nonnegative multiple of a Heaviside composite function to a lifted formulation for arbitrarily signed multiples of the Heaviside composite function, based on which we show that an epistationary solution of the given Heaviside composite program with broad classes of B-differentiable component functions can in principle be approximately computed by surrogation methods.

It’s getting personal: exploring our inner world in the regenerative paradigm shift

Regenerative tourism argues that addressing the current ecological crisis requires inner transformation, referring to changes in people’s mindsets, values, beliefs, and worldviews. Combined, they influence the systems we create and, as such, represent deep levers for systems change. Yet, an in-depth analysis of the inner dimension in the context of regeneration is missing. It is unclear which qualities foster inner development towards regenerative change. Using the concept of leverage points and through a scoping review and thematic analysis of 309 articles on regenerative approaches, regenerative tourism, and the inner dimension of sustainability, this study proposes the Inner Regenerative Development Framework, a whole-person approach constituting aspects of our inner world that enhance our ability to work regeneratively; conceptualised here as Inner Regenerative Development. The framework brings together cognitive, affective, grounded, and holistic aspects of ourselves, encompassing 12 inner leverage points and 85 inner qualities serving as the basis for interventions, a few of which are proposed as starting points for inner-outer transformation. Collectively, these elements highlight the inner domains, capacities, and practices that can be cultivated to support regenerative tourism from the inside out.

Impact of Employee Grievance Management on Organizational Performance

Purpose: This paper examined the impact of employees' grievance management on organizational performance. The paper derives from conceptual points of view in available literatures that there is a coefficient relationship between the variables: employees' grievances, and organizational performance; hence, effective management of employee grievance is essential for harmonious workplace relationship, team spirit, employees' loyalty and commitment, as well as improved organizational productivity and performance. In the face of this necessity, there is still a relative lack of, or poor employee grievance management in organizations thereby giving rise to negative organizational outcomes such as reduced productivity, absenteeism, violation of orders, indiscipline and reduced quality of work. The study thus aims to show how employees' grievances directly impact on performance. Methodology: In doing this, the study is designed using secondary data, analyzed in line with content analysis model and developed on the theoretical foundation of Rahim and Bonoma’s grievance management model. The analysis is anchored on two research objectives and research questions, developed to test recurrent hypotheses. Findings: From the findings, the study concludes that effective employee grievance management is vital for effective harmonious management-labour relationship which helps to enhance organizational performance. Recommendations: It is recommended among others that grievances should be handled routinely through set-up structures designed exclusively for that purpose in order to drastically reduce employees' grievances in the workplace.

The “mythologies” of women at work, interrupted: feminist origins antenarratives from Harvard Business Review and Western University’s The Quarterly, Part I

Purpose The author aims to walk beside the singular privileged class of White women’s suffrage feminist origin story to (re)construct plausible feminist fragmented threads as antenarratives in the context of business management education. To accomplish this (re)assembling of threads, the author examined two North American business trade publications created and used within two business schools, Harvard University’s Harvard Business Review (HBR), established in 1922, and Western University’s The Quarterly Review of Commerce (The Quarterly), established in 1933. Design/methodology/approach The author carefully reviewed almost 4,000 articles from HBR and The Quarterly, focusing on 308 articles that addressed the experiences of complex women. With this subset of collected articles, the author highlighted overlooked details, accidents and errors, generating interest and curiosity about the emergence of these fragmented and paradoxical origins that align with Foucault's histories of errors. By grouping these narrative fragments into themes and conducting a critical discourse analysis that incorporated influences from the external environment, the author reconstructed plural feminist origins antenarratives. Findings The themes discovered, including women as consumers, explicit working women concerns, women as authors/coauthors, diversity and social justice initiatives, and women in higher education/training, are not merely descriptive observations. They are the building blocks for identifying and analyzing the power relations circulating among feminist origins antenarratives within management education circles. These antenarratives include shedding light on women working in capitalist contexts, the educational needs of business women, and men and naming (but not breaking) the “mythologies” of women at work. These findings are transformative to the understanding of plural feminist origins. Originality/value The uniqueness of this work lies in its threefold contributions: moving away from the notion of a singular feminist origin story and instead embracing the complexity of multiple, paradoxical and incomplete origins; shedding light on the spectrum of power relations – ranging from productive to oppressive – that shaped the experiences of women in two management educational circles during the first half of the 20th century; and introducing the concept of inflection points, which underscores the fluidity of knowledge.
