An observational study of the nurse-patient relationship in an oncology setting
Creators: name: Lotzkar, Michelle
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to describe the development of a nurse-patient relationship (NPR) in an oncology setting. Although theorists and researchers have attempted to explain the nature of the NPR, and have recognized its potential benefits, further exploration is necessary to increase our understanding of the complexities inherent in NPRs. Using qualitative ethological research methods, videotaped recordings (VTRs) of the interactions between a nurse and patient on an active cancer treatment ward were used to investigate and delineate important features of nurse-patient interactions (NPIs) that reflect the development of a NPR. A sample of sixty videotaped NPIs that represented all the interactions between one patient and one nurse over a three-day period was selected for this study. The data analysis of the VTRs was completed by reviewing all the interactions, identifying behavioral clusters, identifying constituents of behavioral clusters and constructing an ethogram. The findings of this study were validated and extended by using a focus group meeting with clinical nurse experts. Several behavioral clusters were found on each day of this three-day relationship which reflected a dynamic and complex interplay between the nurse and patient. Some patterns of interaction were observed in all three days of the relationship, while others changed as the relationship developed. A dominant theme observed in most of the interaction patterns was the one of humor. The findings of this study suggested active participation of both the nurse and patient in relationship development. The development of this NPR was reflected in the changes observed i n the behaviors of both the nurse and patient over the course of three days. The NPR is complex. Awareness of nurse and patient behaviors that contribute to the development of effective NPRs may challenge oncology nurses to reflect on their own practice and to consciously incorporate behaviors that contribute to effective NPRs into their patient care.

description: The internet has opened multiple channels of communication using digital media and consumers are using these tools to review their experiences with medical providers and dentists. A literature search on the role of technology and digital media revealed profound differences amongst generations regarding the use of digital media for selecting health care providers. The purpose of this study was to determine the extent of generational differences between Millennials, Generation X and Baby Boomers in regard to their use of digital media and the impact it has on their selection of a dentist. A total of nine thousand surveys were distributed to the general public via a secure server powered by UIC “Qualtrics”. One hundred eighty-six individuals responded to the survey. The survey consisted of eighteen questions that inquired about the use of digital media to obtain access to dental care and use of online services like the ability to make appointments or post online reviews. The results of the study indicate that older generations like Baby boomers rely more on word of mouth in finding their dentist while younger generations like Millennials use technology and the internet to find their dentist. Following dentists on social media, looking for online reviews and writing online reviews was also popular amongst the Millennials. The information collected from this investigation will help dentists modify and adjust their marketing strategies in order to more effectively target the various population subgroups based on their preferences of using digital media or traditional marketing.

description: The BD4OPEM project aims to design, develop, and deploy a Marketplace in order to provide innovative energy services for the reliable operation of the smart grid. These energy services will be provided through a marketplace, acting as an open, modular data analysis toolbox and facilitating data exchange and advanced usage. In this way, the data coming from the diverse energy domain sources will be put at the disposal of advanced energy service developers through a marketplace. The main objective of WP7 is to oversee the implementation and demonstration of the services developed in the previous WPs. Through this implementation, the aim is to prove two points:

That the tools developed are compliant with the given objectives and, if not, analyse and identify the reason for the difference and provide recommendations about the tool optimization to reach better results.

That the Marketplace platform and the Analytics toolbox permits flexibility, replicability, and scalability of the services between data providers and service users with adapted features.

Overall, this work package consists in providing the input for the analysis of the impact of the whole system developed during BD4OPEM project and giving recommendation to optimise its use and management. It is as well the opportunity to gather feedbacks from different demonstration sites and their respective leaders upon the platform, the services, and the customer experience. This document describes the results of the implementation of the services for the Turkish demonstration site.
title: The Effects of Nicotine on Growth, Surface Marker Expression, and Osteogenic Capacity of Stem Cells from Human Exfoliated Deciduous Teeth (SHED) and Dental Pulp Stem Cells (DPSC)

description: Background: The gaining popularity of electronic nicotine delivery systems (ENDS) and inhaling aerosols (“vaping”) among young people have exposed them to unprecedented amounts of nicotine. Fourth generation ENDS manufacturers attract the adolescent demographic with a smooth vaping experience with enticing flavors such as “Piña Colada” or “Peppermint Blast.” Components of e-liquids in cartridges of ENDS combine protonated nicotine, also referred as nicotine salts, with flavors in a propylene glycol or vegetable glycerin solvent. Unregulated, high amounts of nicotine in ENDS products have been associated with increased levels of nicotine in the circulating blood of users with an average concentration of about 30ng/mL. Little is known on the effects of protonated nicotine on oral health, specifically on stem cells from human exfoliated deciduous teeth (SHED) and dental pulp stem cells (DPSC), and its implications on the repair and regeneration processes for the soft and hard tissues. Objectives: The aim of this study is to evaluate the effects of nicotine on SHED and DPSC cell growth, surface marker expression, and osteogenic differentiation capacity.
Methods: Isolated SHED cells and DPSC cells were seeded in separate T-75 flasks with culture medium treated with 0ng/mL, 30ng/mL, and 300ng/mL of concentrated protonated nicotine. Population doublings were recorded over several passages once confluency was reached. The antigen surface marker expressions of SHED and DPSC sample populations were analyzed using flow cytometry. SHED and DPSC cell populations were cultured in osteogenic induction media, then after 7 days, collected for RNA Isolation and RT-qPCR gene expression of runt-related transcription factor 2 (RUNX2), secreted phosphoprotein 1 (SPP1), and bone gammacarboxyglutamate protein (BGLAP).
Results: Population doublings showed significant decrease in growth rate of both 30ng/mL and 300ng/mL nicotine treated SHED and DPSC cell populations compared to the untreated controls. Cell surface marker expression of nicotine treated SHEDs and DPSCs were consistent with the typical presentation of human mesenchymal stem cells (MSC). Analysis of cell populations from 0ng/mL, 30ng/mL and 300ng/mL nicotinic concentrations cultured in osteoblast inducing media using qPCR revealed no changes in RUNX2, SPP1 and BGLAP gene expression compared to undifferentiated controls.
Conclusion: Nicotine exhibits an adverse effect on the proliferation rate of SHEDs and DPSCs but shows no effect on their stem cell marker expression and osteogenic differentiation capacity.

description: This study employed a turning point analysis to document milestones that influence the development of activist identities in young girls. All participants (N = 19), between the ages of 16–23 years old, self-identified as an activist and participated in activist spaces. Through an analysis of semi-structured interviews and arts-based elicitation research, data revealed several turning point events that influenced participants’ activist identity development, as well as their personal definition of activism. These turning points, paired with the communication theory of identity (CTI) framework, highlighted how girl activists negotiate gaps in their activist identities by communicatively co-constructing an evolving definition of activism. Theoretical and practical implications are discussed regarding turning points in relation to identity development and gendered disparities in activist spaces.

description: We present an exact solution of percolation in a generalized class of Watts-Strogatz graphs defined on a 1-dimensional underlying lattice. We find a non-classical critical point in the limit of the number of long-range bonds in the system going to zero, with a discontinuity in the percolation probability and a divergence in the mean finite-cluster size. We show that the critical behavior falls into one of three regimes depending on the proportion of occupied long-range to unoccupied nearest-neighbor bonds, with each regime being characterized by different critical exponents. The three regimes can be united by a single scaling function around the critical point. These results can be used to identify the number of long-range links necessary to secure connectivity in a communication or transportation chain. As an example, we can resolve the communication problem in a game of "telephone".

description: The halo of the Milky Way provides a laboratory to study the properties of the shocked hot gas that is predicted by models of galaxy formation. There is observational evidence of energy injection into the halo from past activity in the nucleus of the Milky Way; however, the origin of this energy (star formation or supermassive-black-hole activity) is uncertain, and the causal connection between nuclear structures and large-scale features has not been established unequivocally. Here we report soft-X-ray-emitting bubbles that extend approximately 14 kiloparsecs above and below the Galactic centre and include a structure in the southern sky analogous to the North Polar Spur. The sharp boundaries of these bubbles trace collisionless and non-radiative shocks, and corroborate the idea that the bubbles are not a remnant of a local supernova but part of a vast Galaxy-scale structure closely related to features seen in gamma-rays. Large energy injections from the Galactic centre are the most likely cause of both the γ-ray and X-ray bubbles. The latter have an estimated energy of around 10$^{56}$ erg, which is sufficient to perturb the structure, energy content and chemical enrichment of the circumgalactic medium of the Milky Way.

A physical model for the magnetosphere of Uranus at solstice time

Year: 2020
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Uranus is the only planet in the Solar System whose rotation axis and orbital plane are nearly parallel to each other. Uranus is also the planet with the largest angle between the rotation axis and the direction of its magnetic dipole (roughly $59^\circ$). Consequently, the shape and structure of its magnetospheric tail is very different to those of all other planets in whichever season one may consider. We propose a magnetohydrodynamic model for the magnetic tail of Uranus at solstice time. One of the main conclusions of the model is that all magnetic field lines forming the extended magnetic tail follow the same qualitative evolution from the time of their emergence through the planet's surface and the time of their late evolution after having been stretched and twisted several times downstream of the planet. In the planetary frame, these field lines move on magnetic surfaces that wind up to form a tornado-shaped vortex with two foot points on the planet (one in each magnetic hemisphere). The centre of the vortex (the eye of the tornado) is a simple double helix with a helical pitch (along the symmetry axis $z$) $λ=τ[v_z+B_z/(μ_0ρ)^{1/2}],$ where $τ$ is the rotation period of the planet, $μ_0$ the permeability of vacuum, $ρ$ the mass density, $v_z$ the fluid velocity, and $B_z$ the magnetic field where all quantities have to be evaluated locally at the centre of the vortex. In summary, in the planetary frame, the motion of a typical magnetic field of the extended Uranian magnetic tail is a vortical motion, which asymptotically converges towards the single double helix, regardless of the line's emergence point on the planetary surface.

description: We have investigated the structure of the pulsating atmosphere of one of the best studied rapidly oscillating Ap stars, HD 24712. For this purpose we analyzed spectra collected during 2001-2004. An extensive data set was obtained in 2004 simultaneously with the photometry of the Canadian MOST mini-satellite. This allows us to connect directly atmospheric dynamics observed as radial velocity variations with light variations seen in photometry. We directly derived for the first time and for different chemical elements, respectively ions, phase shifts between photometric and radial velocity pulsation maxima indicating, as we suggest, different line formation depths in the atmosphere. This allowed us to estimate for the first time the propagation velocity of a pulsation wave in the outer stellar atmosphere of a roAp star to be slightly lower than the sound speed. We confirm large pulsation amplitudes (150-400 m/s) for REE lines and the Halpha core, while spectral lines of the other elements (Mg, Si, Ca, and Fe-peak elements) have nearly constant velocities. We did not find different pulsation amplitudes and phases for the lines of rare-earth elements before and after the Balmer jump, which supports the hypothesis of REE concentration in the upper atmosphere above the hydrogen line-forming layers. We also discuss radial velocity amplitudes and phases measured for individual spectral lines as tools for a 3D tomography of the atmosphere of HD 24712.

description: We discuss the mass of the (physical component of the) Higgs boson in one-loop and top-quark mass approximation. For this the minimal Standard Model is regarded as a specific (parameterized) gauge theory of Dirac type. It is shown that the latter formulation, in contrast to the usual description of the Standard Model, gives a definite value for the Higgs mass. The predicted value for the Higgs mass depends on the value addressed to the top mass m_T. We obtain m_H= 186 \pm 8 GeV for m_T = 174 \pm 3 GeV (direct observation of top events), resp. m_H = 184 \pm 22 GeV for m_T = 172 \pm 10 GeV (Standard Model electroweak fit). Although the Higgs mass is predicted to be near the upper bound, m_H is in full accordance with the range 114 \leq m_H < 193 GeV that is allowed by the Standard Model. We show that the inclusion of (Dirac) massive neutrinos does not alter the results presented. We also briefly discuss how the derived mass values are related to those obtained within the frame of non-commutative geometry.

description: We investigate a well defined heterostructure constituted by magnetic Fe layers sandwiched between graphene (Gr) and Ir(111). The challenging task to avoid Fe-C solubility and Fe-Ir intermixing has been achieved with atomic controlled Fe intercalation at moderate temperature below 500 K. Upon intercalation of a single ordered Fe layer in registry with the Ir substrate, an intermixing of the Gr bands and Fe d states breaks the symmetry of the Dirac cone, with a downshift in energy of the apex by about 3 eV, and well-localized Fe intermixed states induced in the energy region just below the Fermi level. First principles electronic structure calculations show a large spin splitting of the Fe states, resulting in a majority spin channel almost fully occupied and strongly hybridized with Gr π states. X-ray magnetic circular dichroism on the Gr/Fe/Ir heterostructure reveals an ordered spin configuration with a ferromagnetic response of Fe layer(s), with enhanced spin and orbital configurations with respect to the bcc-Fe bulk values. The magnetization switches from a perpendicular easy magnetization axis when the Fe single layer is lattice matched with the Ir(111) surface to a parallel one when the Fe thin film is almost commensurate with graphene.
Risky Business: Sexual Behavior and Cocaine Use Disorder

description: Individuals who use crack cocaine are at an increased risk for human immunodeficiency virus (HIV) transmission, primarily due to risky sexual behavior. Previous literature has suggested that both substance use and risky sexual behavior may be driven by similar processes; although, it is unclear which mechanism would be the optimal target in dual interventions for cocaine use disorder and sexual risk behavior. Two analyses examined five emotional and behavioral mechanisms that have been associated with drug use and risky sexual behavior. Results from the analyses suggested that emotion regulation, experiential avoidance, distress tolerance, mindfulness, and delay discounting were not significantly related to risky sexual behavior or cocaine use severity among individuals with cocaine use disorder.

description: This thesis explains how Zikhron Ya’akov by Rabbi Ya’akov Halevi Lifshitz (1838 -1921) represents not simply a memoir of a deceased Rabbi, but avant-garde counter-history as well as mussar literature. Defining Zikhron Ya’akov as a counter-history involves accepting that Lifshitz himself wrote extensively, but not as a demure marginal autobiographer recounting his story in a modest memoir. Rather, it involves accepting that Lifshitz wrote as a radical historiographer, attempting to focus on his own self and effectively identifying as a creator of a controversial new system of thinking. Writing under rapidly changing historical circumstances, Lifshitz neither writes a history, nor does he identify as a historian. As a polemicist and a rhetorical writer whose work is now classed in the complex system of mussar literature, Lifshitz creates a historiography for posterity linked closely with his own legacy. The translations included in the appendix help guide the reader through material covered by the thesis.

description: As machine learning becomes a more mainstream technology, the objective for governments and public sectors is to harness the power of machine learning to advance their mission by revolutionizing public services. Motivational government use cases require special considerations for implementation given the significance of the services they provide. Not only will these applications be deployed in a potentially hostile environment that necessitates protective mechanisms, but they are also subject to government transparency and accountability initiatives which further complicates such protections. In this paper, we describe how the inevitable interactions between a user of unknown trustworthiness and the machine learning models, deployed in governments and public sectors, can jeopardize the system in two major ways: by compromising the integrity or by violating the privacy. We then briefly overview the possible attacks and defense scenarios, and finally, propose recommendations and guidelines that once considered can enhance the security and privacy of the provided services.

description: The largest galaxy systems in the cosmic web are superclusters, overdensity regions of galaxies, groups, clusters, and filaments. Low-density regions around superclusters are called basins of attraction or cocoons. In my talk I discuss the properties of galaxies, groups, and filaments in the A2142 supercluster and its cocoon at redshift $z \approx 0.09$. Cocoon boundaries are determined by the lowest density regions around the supercluster. We analyse the structure, dynamical state, connectivity, and galaxy content of the supercluster, and its high density core with the cluster A2142. We show that the main body of the supercluster is collapsing, and long filaments which surround the supercluster are detached from it. Galaxies with very old stellar populations lie not only in the central parts of clusters and groups in the supercluster, but also in the poorest groups in the cocoon.

Metastability of R-Charged Black Holes

description: The global stability of R-charged AdS black holes in a grand canonical ensemble is examined by eliminating the constraints from the action, but without solving the equations of motion, thereby constructing the reduced action of the system. The metastability of the system is found to set in at a critical value of the chemical potential which is conjugate to the R-charge. The relation among the small black hole, large black hole and the instability is discussed. The result is consistent with the metastability found in the AdS/CFT-conjectured dual field theory. The "renormalized" temperature of AdS black holes, which has been rather ad hoc, is suggested to be the boundary temperature in the sense of AdS/CFT correspondence. As a byproduct of the analysis, we find a more general solution of the theory and its properties are briefly discussed.

description: We published spectra of phosphine molecules in Venus' clouds, following open-science principles in releasing data and scripts (with community input leading to ALMA re-processing, now benefiting multiple projects). Some misconceptions about de-trending of spectral baselines have also emerged, which we address here. Using the JCMT PH3-discovery data, we show that mathematically-correct polynomial fitting of periodic ripples does not lead to "fake lines" (probability < ~1%). We then show that the ripples can be characterised in a non-subjective manner via Fourier transforms. A 20 ppb PH3 feature is ~5σ compared to the JCMT baseline-uncertainty, and is distinctive as a narrow perturber of the periodic ripple pattern. The structure of the FT-derived baseline also shows that polynomial fitting, if unguided, can amplify artefacts and so artificially reduce significance of real lines.

description: Starting from a microscopic tight-binding model and using second order perturbation theory, we derive explicit expressions for the intrinsic and Rashba spin-orbit interaction induced gaps in the Dirac-like low-energy band structure of an isolated graphene sheet. The Rashba interaction parameter is first order in the atomic carbon spin-orbit coupling strength $ξ$ and first order in the external electric field $E$ perpendicular to the graphene plane, whereas the intrinsic spin-orbit interaction which survives at E=0 is second order in $ξ$. The spin-orbit terms in the low-energy effective Hamiltonian have the form proposed recently by Kane and Mele. \textit{Ab initio} electronic structure calculations were performed as a partial check on the validity of the tight-binding model.

description: Photographs play a significant role as unique visual sources in documenting historical events, ethnographic features, and cultural processes. They provide opportunities for reconstructing authentic historical realities and facilitate a deeper understanding of daily life across various cultures and societies. From an ethnographic perspective, the source significance of photographs lies in their ability to directly illustrate the traditional lifestyles, clothing styles, religious and social ceremonies, customs, and rituals of societies. From a scientific viewpoint, photographs serve as essential primary sources in disciplines such as history, anthropology, and ethnology, enabling researchers to chronologically trace cultural and social transformations. Furthermore, when analyzing photographs as historical sources, it is crucial to consider their origin, authorship, social function, and the specific purpose for which they were produced. This methodological approach significantly enhances the historical and scientific value of photographs.

Keywords: photographs, source, historical, ethnographic, scientific, history of Turkistan, visual, anthropology, theoretical-methodological, society, colonialism, ideology.

description: Aim: To determine the programmed death ligand-1 (PD-L1) expression rates in sarcomatoid lung carcinomas and to compare clinicopathologic features and survival rates of PD-L1-positive and negative patients. Methods: PD-L1 expression was evaluated in 65 surgically resected sarcomatoid carcinomas. The clinicopathologic features of cases with PD-L1-positive and negative tumors were compared. Kaplan-Meier survival analysis was performed. Multiple Cox proportional hazard regression analysis was performed to determine independent predictors of overall survival. Results: PD-L1 antibody positivity was found in 72.3% of surgically resected sarcomatoid lung carcinomas. Regarding histopathologic subtypes, PD-L1 expression was positive in 80.4% of pleomorphic carcinomas, 62.5% of spindle- and/or giant-cell carcinomas, and 16.7% of carcinosarcomas. Pleural invasion was observed in 68.1% of PD-L1-positive cases and 27.8% of PD-L1-negative cases (p = 0.008). No difference in survival was found between PD-L1-positive and negative tumors. The only factor significantly associated with poor survival was the pathological stage of the tumor. Conclusions: This study reveals a high rate of PD-L1 positivity in a large number of sarcomatoid lung carcinoma cases with pleomorphic carcinoma, spindle- and/or giantcell carcinoma, and carcinosarcoma subtypes. The only significantly different clinicopathologic feature in PD-L1-positive cases is pleural invasion. PD-L1 positivity is not a significant predictor of survival in sarcomatoid lung carcinomas.

description: Biosensors and wearable sensor systems with transmitting capabilities are currently developed and used for the monitoring of health data, exercise activities, and other performance data. Unlike conventional approaches, these devices enable convenient, continuous, and/or unobtrusive monitoring of user behavioral signals in real time. Examples include signals relative to body motion, body temperature, blood flow parameters and a variety of biological or biochemical markers and, as will be shown in this chapter here, individual grip force data that directly translate into spatiotemporal grip force profiles for different locations on the fingers and palm of the hand. Wearable sensor systems combine innovation in sensor design, electronics, data transmission, power management, and signal processing for statistical analysis, as will be further shown herein. The first section of this chapter will provide an overview of the current state of the art in grip force profiling to highlight important functional aspects to be considered. In the next section, the contribution of wearable sensor technology in the form of sensor glove systems for the real-time monitoring of surgical task skill evolution in novices training in a simulator task will be described on the basis of recent examples. In the discussion, advantages and limitations will be weighed against each other.

description: HectoMAP is a dense, red-selected redshift survey to a limiting $r = 21.3$ covering 55 square degrees in a contiguous 1.5$^\circ$ strip across the northern sky. This region is also covered by the Subaru/Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) photometric survey enabling a range of applications that combine a dense foreground redshift survey with both strong and weak lensing maps. The median redshift of HectoMAP exceeds 0.3 throughout the survey region and the mean density of the redshift survey is $\sim 2000$ galaxies deg$^{-2}$. Here we report a total of 17,313 redshifts in a first data release covering 8.7 square degrees. We include the derived quantities D$_{n}4000$ and stellar mass for nearly all of the objects. Among these galaxies, 8117 constitute a 79\% complete red-selected subsample with $r \leq 20.5$ and an additional 4318 constitute a 68\% complete red-selected subsample with $20.5 < r < 21.3$. As examples of the strengths of HectoMAP data we discuss two applications: refined membership of redMaPPer photometrically selected clusters and a test of HSC photometric redshifts. We highlight a remarkable redMaPPer strong lensing system. The comparison of photometric redshifts with spectroscopic redshifts in a dense survey uncovers subtle systematic issues in the photometric redshifts.

description: In the bacterium Escherichia coli, selection of the division site involves pole-to-pole oscillations of the proteins MinD and MinE. Different oscillation mechanisms based on cooperative effects between Min-proteins and on the exchange of Min-proteins between the cytoplasm and the cytoplasmic membrane have been proposed. The parameters characterizing the dynamics of the Min-proteins in vivo are not known. It has therefore been difficult to compare the models quantitatively with experiments. Here, we present in vivo measurements of the mobility of MinD and MinE using fluorescence correlation spectroscopy. Two distinct time-scales are clearly visible in the correlation curves. While the faster time-scale can be attributed to cytoplasmic diffusion, the slower time-scale could result from diffusion of membrane-bound proteins or from protein exchange between the cytoplasm and the membrane. We determine the diffusion constant of cytoplasmic MinD to be approximately 16μ^{2}/s, while for MinE we find about 10μ^{2}/s, independently of the processes responsible for the slower time-scale. Implications of the measured values for the oscillation mechanism are discussed.

description: Background: It is of biological interest to make genome-wide predictions of the locations of DNA melting bubbles using statistical mechanics models. Computationally, this poses the challenge that a generic search through all combinations of bubble starts and ends is quadratic. Results: An efficient algorithm is described, which shows that the time complexity of the task is O(NlogN) rather than quadratic. The algorithm exploits that bubble lengths may be limited, but without a prior assumption of a maximal bubble length. No approximations, such as windowing, have been introduced to reduce the time complexity. More than just finding the bubbles, the algorithm produces a stitch profile, which is a probabilistic graphical model of bubbles and helical regions. The algorithm applies a probability peak finding method based on a hierarchical analysis of the energy barriers in the Poland-Scheraga model. Conclusions: Exact and fast computation of genomic stitch profiles is thus feasible. Sequences of several megabases have been computed, only limited by computer memory. Possible applications are the genome-wide comparisons of bubbles with promotors, TSS, viral integration sites, and other melting-related regions.

description: This note begins with an introduction to the inverse isospectral problem popularized by M. Kac's 1966 article in the American Mathematical Monthly, "Can one hear the shape of a drum?" Although the answer has been known for some twenty years now, many open problems remain. Intended for general audiences, readers are challenged to complete exercises throughout this interactive introduction to inverse spectral theory. Following the introduction, the main techniques used in inverse isospectral problems are collected and discussed. These are then used to prove that one can hear the shape of: parallelograms, acute trapezoids, and the regular n-gon. Finally, we show that one can realistically hear the shape of the regular n-gon amongst all convex n-gons because it is uniquely determined by a finite number of eigenvalues; the sound of symmetry can really be heard!

description: The expected total cost function is developed by using a Markovian approach. The imperfect production and inventory control model is considered and integrated with an irreducible discrete time Markov Chain. Two Markov Chain models are developed with/without time factor. The former model with time factor has higher accuracy in the expected total cost. The optimal total cost and detailed production plan for each state are accomplished. Two applications for the developed Markov Chain models are established. The scheduling hard time windows between two production processes. Moreover, optimal maintenance actions for the preventive maintenance, inspection, and minimal repair are attained. Finally, sensitivity analysis is performed in two categories. The first category is the by varying of the production and demand rates and the second category is by varying the production and inventory control model’s parameters. Their effects are discovered on the developed Markov Chain model.
