description: Rationale and Objectives: Sarcopenia is defined as skeletal muscle loss and can be assessed by cross-sectional imaging. Our aim was to establish the effect of sarcopenia on relevant outcomes in patients with pancreatic ductal adenocarcinoma (PDAC) in curative and palliative settings based on a large patient sample. Materials and Methods: MEDLINE library, EMBASE and SCOPUS databases were screened for the associations between sarcopenia and mortality in patients with PDAC up to March 2022. The primary endpoint of the systematic review was the hazard ratio of Sarcopenia on survival. 22 studies were included into the present analysis. Results: The included 22 studies comprised 3958 patients. The prevalence of sarcopenia was 38.7%. Sarcopenia was associated with a higher prevalence in the palliative setting (OR 53.23, CI 39.00-67.45, p<0.001) compared to the curative setting (OR 36.73, CI 27.81-45.65, p<0.001). Sarcopenia was associated with worse OS in the univariable (HR 1.79, CI 1.41-2.28, p<0.001) and multivariable analysis (HR 1.62, CI 1.27-2.07, p<0.001) in the curative setting. For the palliative setting the pooled hazards ratio showed that sarcopenia was associated with overall survival (HR 1.56, CI 1.21-2.02, p<0.001) as well as in multivariable analysis (HR 1.77, CI 1.39-2.26, p<0.001). Sarcopenia was not associated with a higher rate of post-operative complications in univariable analysis (OR 1.10, CI 0.70-1.72, p = 0.69). Conclusion: Sarcopenia occurs in 38.7% of patients with pancreatic cancer, significantly more in the palliative setting. Sarcopenia is associated with overall survival in both settings. The assessment of sarcopenia is therefore relevant for personalized oncology. Sarcopenia is not associated with postoperative complications.

description: Chymotrypsin C (CTRC) is a digestive serine protease produced by the pancreas that regulates intrapancreatic trypsin activity and provides a defensive mechanism against chronic pancreatitis (CP). CTRC exerts its protective effect by promoting degradation of trypsinogen, the precursor to trypsin. Loss-of-function missense and microdeletion variants of CTRC are found in around 4% of CP cases and increase disease risk by approximately 3-7-fold. In addition, a commonly occurring synonymous CTRC variant c.180C>T (p.Gly60=) was reported to increase CP risk in various cohorts but a global analysis of its impact has been lacking. Here, we analyzed the frequency and effect size of variant c.180C>T in Hungarian and pan-European cohorts, and performed meta-analysis of the new and published genetic association data. When allele frequency was considered, meta-analysis revealed an overall frequency of 14.2% in patients and 8.7% in controls (allelic odds ratio (OR) 2.18, 95% confidence interval (CI) 1.72–2.75). When genotypes were examined, c.180TT homozygosity was observed in 3.9% of CP patients and in 1.2% of controls, and c.180CT heterozygosity was present in 22.9% of CP patients and in 15.5% of controls. Relative to the c.180CC genotype, the genotypic OR values were 5.29 (95% CI 2.63–10.64), and 1.94 (95% CI 1.57–2.38), respectively, indicating stronger CP risk in homozygous carriers. Finally, we obtained preliminary evidence that the variant is associated with reduced CTRC mRNA levels in the pancreas. Taken together, the results indicate that CTRC variant c.180C>T is a clinically relevant risk factor, and should be considered when genetic etiology of CP is investigated.

description: We present a technique for addressing single NV$^{-}$ center spins in diamond over macroscopic distances using a tunable dielectric microwave cavity. We demonstrate optically detected magnetic resonance (ODMR) for a single NV$^{-}$ center in a nanodiamond (ND) located directly under the macroscopic microwave cavity. By moving the cavity relative to the ND, we record the ODMR signal as a function of position, mapping out the distribution of the cavity magnetic field along one axis. In addition, we argue that our system could be used to determine the orientation of the NV$^{-}$ major axis in a straightforward manner.
Access and Use of Dental Services in the Medicaid Pediatric Oncology Population in North Carolina

Year: 2023

description: Purpose: Children with complex medical needs face difficulties in accessing dental care. The aim of this study was to investigate access and utilization of dental services among publicly insured children with a cancer diagnosis in North Carolina.

Methods: Cancer patients ages 0 to 21 were identified using ICD-10 diagnosis codes and CPT procedure codes in NC Medicaid claims data between 2016 and 2019. I used dental claims to estimate two metrics: the percentage of patients who received any dental service (i.e., “access rate”) and among those, the percentage of patients who received preventive dental services (i.e., “prevention ratio”). These estimates among cancer patients were compared to those among the entire NC Medicaid population, as well as between age groups, regions of NC, and federal fiscal years. 

Results: I identified 5,635 NC Medicaid enrollees ages 0-21 in the period 2016 to 2019 who were cancer patients. Access rates and prevention ratios remained relatively stable during the study period, ranging between 52-54% and 89-90%, respectively. Cancer patients’ access rates were similar to the overall population (i.e., 51-52%) whereas their prevention were slightly lower than the overall population (i.e., 94%). Considerable variation in both dental access and prevention was found between age groups (e.g., utilization peaked among 6-9-year-olds) and state regions. 

Conclusions: Dental utilization among Medicaid-enrolled cancer patients in NC is similar to the utilization in the general population. Even while a considerable proportion of oncologic patients receive preventive dental services, there appears to be room for improvement, overall and particularly among children under the age of 6.

description: This presentation gives an overview about the structure and objectives of the GGOS Bureau of Products and Standards. The focus is on the BPS activities concerning the updating of the IERS Conventions, mainly related to Chapter 1 "General definitions and numerical standards". It deals with the treatment of the permanent tide in heights as specified in the new International Height Reference System (IHRS), which presribes the IHRF coordinates in the mean-tide system to support oceanographic and hydrographic modelling. In this context, updates for Section 1.1 "Permanent Tide" are proposed. In the second part, the present status concerning numerical standards (Section 1.2 of the IERS Conventions) is addressed. Several updates for the IERS Numerical Standards (see Table 1.1) are proposed and recommendations for future developments are provided..
Nonlocal quantum field theory without acausality and nonunitarity at quantum level: is SUSY the key?

description: The realization of a nonlocal quantum field theory without losing unitarity, gauge invariance and causality is investigated. It is commonly retained that such a formulation is possible at tree level, but at quantum level acausality reappears at one loop. We suggest the the problem of acausality is, in a broad sense, similar to the one about anomalies in quantum field theory. By virtue of this analogy, we suggest that acausal diagrams resulting from the fermionic sector and the bosonic one might cancel each other, with a suitable content of fields and suitable symmetries. As a simple example, we show how supersymmetry can alleviate this problem in a simple and elegant way, i.e., by leading to exact cancellations of harmful diagrams, to all orders of perturbation theory, in the case of a nonlocal Wess-Zumino model. On the other hand, the same is true for a super Yang-Mills model, but in this case, other important acausal diagrams are also originating from supersymmetric D-terms. As a consequence, we conjecture that, for a generic gauge theory, an infinite number of superfields are needed in order to obtain a complete cancellation between all diagrams. This framework is naturally occurring in string theory, where infinite Kaluza-Klein towers of higher-spin fields are generally predicted.
description: Supergraphs reformulation in non-local case are added, with a formal derivation of these. More explicit calculations, in main interesting one-loop processes, are explicitly shown. More comments and references. Main results and Conclusions remain the same
Bloodied Eyes, Dancing Dolls, and Other Hoffmannian Motifs in Nabokov’s King, Queen, Knave
Creators: name: Masing-Delic, Irene
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Vladimir Nabokov’s second novel Korol’, Dama, Valet (1928; henceforth KDV), which would become the “reworked” English novel King, Queen, Knave (1968; henceforth KQK), contains numerous Hoffmannian motifs, specifically from the story “The Sandman” (“Der Sandmann,” 1816). The main ones are: “bloodied eyes” and optical instruments that, instead of improving the capacity of the human eye to see reality, do the opposite—make people “see” what they imagine. In Nabokov’s novel we have these motifs transformed into Franz’s (the “knave”’s) extreme shortsightedness and complete dependence on his glasses, which are “corrective,” yet create delusions. There are also the motifs of automata, and of uncanny characters in our very midst. The “king’s” (businessman Dreyer’s) fascination with automata, as well as his unwavering devotion to his coldly calculating wife, are akin to Nathanael’s enchantment with the doll Olympia. As for uncanny characters, there is Franz’s landlord, who resembles the “mouse king” from Hoffmann’s “The Nutcracker and the Mouse King,” as well as the demonic inventor of automannequins. To my knowledge, this prominent Hoffmannian presence in KDV-KQK has received only limited attention in Nabokov criticism. This does not mean that Nabokov’s interest in E. T. A. Hoffmann during his Berlin period has gone unnoticed.

description: X-ray photoelectron spectroscopy (XPS) combined with first principles modeling is a powerful tool for determining the chemical composition and electronic structure of novel materials. Of these, graphene is an especially important model system for understanding the properties of other carbon nanomaterials. Here, we calculate the carbon 1$\textit{s}$ core level binding energy of pristine graphene using two methods based on density functional theory total energy differences: a calculation with an explicit core-hole ($Δ$KS), and a novel all-electron extension of the delta self-consistent field ($Δ$SCF) method. We study systematically their convergence and computational workload, and the dependence of the energies on the chosen exchange-correlation functional. The $\mathrmΔ$SCF method is computationally more expensive, but gives consistently higher C 1$\textit{s}$ binding energies. Although there is a significant functional dependence, the binding energy calculated using the PBE functional is found to be remarkably close to what has been measured for graphite.

description: This paper is a continuation of our study of compact, power compact, Riesz, and quasicompact endomorphisms of commutative Banach algebras. Previously it has been shown that if $B$ is a unital commutative semisimple Banach algebra with connected character space, and $T$ is a unital endomorphism of $B$, then $T$ is quasicompact if and only if the operators $T^n$ converge in operator norm to a rank-one unital endomorphism of $B$. In this note the discussion is extended in two ways: we discuss endomorphisms of commutative Banach algebras which are semiprime and not necessarily semisimple; we also discuss commutative Banach algebras with character spaces which are not necessarily connected. In previous papers we have given examples of commutative semisimple Banach algebras $B$ and endomorphisms $T$ of $B$ showing that $T$ may be quasicompact but not Riesz, $T$ may be Riesz but not power compact, and $T$ may be power compact but not compact. In this note we give examples of commutative, semiprime Banach algebras, some radical and some semisimple, for which every quasicompact endomorphism is actually compact.

The “Overcoat” of Nabokov’s Luzhin: Defense as Self-Destruction
Creators: name: Masing-Delic, Irene
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This article traces the allusions to Nikolai Gogol’s “The Overcoat” (“Shinel,” 1842) in Vladimir Nabokov’s third novel, Zashchita Luzhina (1929–1930; The Defense, 1964) and presents the chess-obsessed Luzhin as a latter-day calligraphy-obsessed Akaky Akakievich. This Gogolian trajectory is complemented by the theme of the “loss of music,” where “music” is largely synonymous with “inspiration.” The loss of inspiration is linked to the young Luzhin’s autistic alienation from his family and other human relationships, not least erotic ones. The convergence of these two themes points to Luzhin’s fear of life and his quest for protection from the dangers of unpredictable existence, first in his obsessive preoccupation with chess, later in marrying a woman who becomes his “overcoat” but not a source of “music.” In one of many ironic reversals in the novel, her protectiveness hastens Luzhin’s self-destruction, as suppressing all reminders of his chess past endows the game with an aura of danger that leads to fatal delusions when chess associations are triggered by chance. Failing to reconcile life and art, separated from his art and left with only “life,” Luzhin is trapped in a pattern he cannot escape — a pattern that resembles the black and white geometry of the chess board which divides reality into irreconcilable opposites.
An exploration of addiction experiences among high performance athletes

description: This PhD thesis explores the phenomenon of addiction in high-performing athletes. The purpose of the research was to better understand athlete addiction by considering three research questions: 1) What it is like to be an addicted athlete? 2) What factors do addicted athletes associate with the development and manifestation of addictive behaviours? 3) How do addicted athletes recover from addiction? Narrative inquiry was used to explore the addiction experiences of high-performing athletes. Participants’ stories were collected using narrative interviews and timelining. Stories were analysed using thematic narrative analysis (Reissman, 2008), enabling participants’ experiences to be examined within the wider context of their lives and histories. Analysis showed that addiction manifested in numerous behaviours (alcohol, gambling, exercise, eating disorders) that could be understood in relation to three characteristics: desire, lack of control, and harm. Participants identified sport as a major influence in the development and manifestation of addiction. Their stories depicted a pathological dedication to performance resembling the performance narrative proposed by Carless and Douglas (2006). Associated with this was an overwhelming fear of failure and rejection that drove their desire for mood-altering addictive behaviours. Addictive behaviours alleviated participants’ distress by either remedying the source of their emotional pain or helping them to escape it. The acceptance of harm as a necessary part of high- performance sport and the power relationships between coach and athlete further contributed to addiction by hindering help-seeking and/or external intervention. Recovery was possible and occurred in two stages:1) reaching a turning point (e.g., rock-bottom), and 2) a dynamic process of restorying in which performance values were challenged and alternative narratives were discovered. Based upon the findings of the thesis, the need for cultural change within high-performance sport environments is highlighted and the potential for sporting bodies (and those within them) to better support athletes is discussed.

description: We investigated the formation of arc-like structures in the infalling envelope around protostars, motivated by the recent Atacama Large Millimeter/Submillimeter Array (ALMA) observations of the high-density molecular cloud core, MC27/L1521F. We performed self-gravitational hydrodynamical numerical simulations with an adaptive mesh refinement code. A filamentary cloud with a 0.1~pc width fragments into cloud cores because of perturbations due to weak turbulence. The cloud core undergoes gravitational collapse to form multiple protostars, and gravitational torque from the orbiting protostars produces arc structures extending up to a 1000~AU scale. As well as on a spatial extent, the velocity ranges of the arc structures, $\sim0.5\,\mathrm{km\,s}^{-1}$, are in agreement with the ALMA observations. We also found that circumstellar disks are often misaligned in triple system. The misalignment is caused by the tidal interaction between the protostars when they undergo close encounters because of a highly eccentric orbit of the tight binary pair.

description: Recent observations by the Atacama Large Millimeter/submillimeter Array (ALMA) of disks around young stars revealed distinct asymmetries in the dust continuum emission. In this work we want to study axisymmetric and non-axisymmetric structures, evocated by the magneto-rotational instability in the outer regions of protoplanetary disks. We combine the results of state-of-the-art numerical simulations with post-processing radiative transfer (RT) to generate synthetic maps and predictions for ALMA. We performed non-ideal global 3D MHD stratified simulations of the dead-zone outer edge using the FARGO MHD code PLUTO. The stellar and disk parameters are taken from a parameterized disk model applied for fitting high-angular resolution multi-wavelength observations of circumstellar disks. The 2D temperature and density profiles are calculated consistently from a given surface density profile and Monte-Carlo radiative transfer. The 2D Ohmic resistivity profile is calculated using a dust chemistry model. The magnetic field is a vertical net flux field. The resulting dust reemission provides the basis for the simulation of observations with ALMA. The fiducial model develops a large gap followed by a jump in surface density located at the dead-zone outer edge. The jump in density and pressure is strong enough to stop the radial drift of particles. In addition, we observe the generation of vortices by the Rossby wave instability (RWI) at the jumps location close to 60 AU. The vortices are steadily generated and destroyed at a cycle of 40 local orbits. The RT results and simulated ALMA observations predict the feasibility to observe such large scale structures appearing in magnetized disks without having a planet.

description: Access to fresh and healthy foods should not be simply a privilege dependent upon the neighborhood in which a person resides. Unfortunately, this is the reality for many across the United States and Durham, North Carolina is no exception. Low-socioeconomic residents who identify as BIPOC (Black, Indigenous, People of Color) and reside in disproportionately affected neighborhoods are most vulnerable. Food inequity leads to many poor health outcomes and the lasting consequences affect health and wellbeing of not only individual residents but entire communities. 
Our team proposes the Healthy Foods for Equitable Nutrition (HFEN) program which connects community partners  to neighborhood convenience stores with enhanced healthy food options to increase access to high quality and nutritious foods. We will use a mixed-methods analysis plan consisting of both quantitative and qualitative data to evaluate the program. Our team will use the data collected through HFEN to advocate for the reinstatement of the Healthy Food Small Retailer/Corner Store Act and use these funds to scale-up the HFEN program by expanding to convenience stores in low-income, BIPOC communities throughout the state of NC. We will use an interdisciplinary approach through collaboration with various stakeholders to promote equity and sustainable food sovereignty among low-income, BIPOC families residing in the neighborhoods of East Durham, Wellons Village, and Y.E. Smith. Through the implementation of this public health program, we aim to reduce existing health disparities and improve the overall health of the priority population.

description: We investigate transformations which are not symmetries of a theory but nevertheless leave invariant the set of all symmetry elements and representations. Generalizing from the example of a three Higgs doublet model with $Δ(27)$ symmetry, we show that the possibility of such transformations signals physical degeneracies in the parameter space of a theory. We show that stationary points only appear in multiplets which are representations of the group of these so-called equivalence transformations. As a consequence, the stationary points are amongst the solutions of a set of homogeneous linear equations. This is relevant to the minimization of potentials in general and sheds new light on the origin of calculable phases and geometrical CP violation.

description: We study topological recursion on the irregular spectral curve $xy^2-xy+1=0$, which produces a weighted count of dessins d'enfant. This analysis is then applied to topological recursion on the spectral curve $xy^2=1$, which takes the place of the Airy curve $x=y^2$ to describe asymptotic behaviour of enumerative problems associated to irregular spectral curves. In particular, we calculate all one-point invariants of the spectral curve $xy^2=1$ via a new three-term recursion for the number of dessins d'enfant with one face.

description: Access to fresh and healthy foods should not be simply a privilege dependent upon the neighborhood in which a person resides. Unfortunately, this is the reality for many across the United States and Durham, North Carolina is no exception. Low-socioeconomic residents who identify as BIPOC (Black, Indigenous, People of Color) and reside in disproportionately affected neighborhoods are most vulnerable. Food inequity leads to many poor health outcomes and the lasting consequences affect health and wellbeing of not only individual residents but entire communities.
Our team proposes the Healthy Foods for Equitable Nutrition (HFEN) program which connects community partners to neighborhood convenience stores with enhanced healthy food options to increase access to high quality and nutritious foods. We will use a mixed-methods analysis plan consisting of both quantitative and qualitative data to evaluate the program. Our team will use the data collected through HFEN to advocate for the reinstatement of the Healthy Food Small Retailer/Corner Store Act and use these funds to scale-up the HFEN program by expanding to convenience stores in low-income, BIPOC communities throughout the state of NC. We will use an interdisciplinary approach through collaboration with various stakeholders to promote equity and sustainable food sovereignty among low-income, BIPOC families residing in the neighborhoods of East Durham, Wellons Village, and Y.E. Smith. Through the implementation of this public health program, we aim to reduce existing health disparities and improve the overall health of the priority population.

description: Inherent movement of a macrocycle comprising a multi-site hydrogen-bonding Hamilton-type receptor in a series of [2]rotaxanes was investigated by dynamic and VT NMR. In these rotaxanes, the varying nature and number of hydrogen-bond motifs and stations on the molecular axles influenced ring dynamics. Triazole stations interact selectively by hydrogen bonding with the isophthalamide amide bonds present in the Hamilton macrocycle and fast shuttling (72 kHz at 25°C) was observed in a two-station variant.

description: Measurement errors affect the properties of obtained optimal estimators. Further, they affect the accuracy of estimation, although the size of the measurement error required to invalidate an estimation method remains unknown. In this study, we described the effects of measurement errors on estimation and the derived asymptotic covariance matrix by using the properties of unbiased estimating equations. We evaluated different estimation methodologies using various combinations of sample sizes and average reliability ratios. Simulation studies have compared estimators in terms of simulated bias, mean squared error, and coverage probability for the slope parameter. By comparing estimation approaches in terms of bias, mean squared error, and coverage probability, we found that the average reliability ratio of 0.65 and a sample size of 20 yielded estimator stability, with only slight differences in these three attributes. If the sample size was increased, the cutoff point for the average reliability ratio could be relaxed. This process has been in this study illustrated using real datasets.
Fundamental Limits for Light Absorption and Scattering Induced by Cooperative Electromagnetic Coupling

description: Absorption and scattering of electromagnetic waves by dielectric media are of fundamental importance in many branches of physics. In this Letter we analytically derived the ultimate upper limits for the absorbed and scattered powers by any system of optical resonators in mutual interaction. We show that these bounds depend only on the geometric configuration given an incident field. We give the conditions to fullfill to reach these limits paving so a way for a rational design of optimal metamaterials.

description: Galaxy rotation curves determined observationally out to a radius well beyond the galaxy cores can provide a critical test of modified gravity models without dark matter. The predicted rotational velocity curve obtained from Scalar-Vector-Tensor Gravity (STVG or MOG) is in excellent agreement with data for the Milky Way without a dark matter halo, with a mass of $5\times 10^{10}\,M_{\odot}$. The velocity rotation curve predicted by modified Newtonian Dynamics (MOND) does not agree with the data.

description: The electronic structure of WTe2 bulk and layers are investigated by using the first principles calculations. The perfect electron-hole (n-p) charge compensation and high carrier mobilities are found in WTe2 bulk, which may result in the large and non-saturating magnetoresistance (MR) observed very recently in the experiment [Ali et al., Nature 514, 205 (2014)]. The monolayer and bilayer of WTe2 preserve the semimetallic property, with the equal hole and electron carrier concentrations. Moreover, the very high carrier mobilities are also found in WTe2 monolayer, indicating that the WTe2 monolayer would have the same extraordinary MR effect as the bulk, which could have promising applications in nanostructured magnetic devices.

description: In recent years, the statistical physics approach is giving us a unique position for understanding a large
 variety of socioeconomic systems and, in particular, cities. The need for better interpretable models
 for cities is critical: understanding the micro-motives behind human behaviour is a necessary step to
 explain their macroscopic social behaviour and to be useful in the decision-making process. One of
 the topics which is worth tackling is the observation, study and understanding of the formation of
 different kinds of hierarchies which could appear inside cities. We here follow the footsteps of the
 Bonabeau model introduced by Eric Bonabeau et al. in 1995 Bonabeau, Theraulaz and Deneubourg
 (1995) and add a second class of agents into the society. The variation of an agent fitness can just
 change by competition, while the total fitness in the society always remains constant. The fundamental
 particularity of the model is that only a pairwise interaction between agents of opposite classes are
 allowed. The main result is that for a broad range of values of the model, the fitness of the agents
 of each class show a clear decays in time except for one or few agents which capture almost all the
 fitness of the system. Furthermore, numerical simulations reveal a singular behaviour from egalitarian
 to hierarchical society for each class as a function of the control parameter 𝜂, playing the role of the
 temperature of the system. The results are invariant in the system size, and they just depend on the
 number of agents of each class. Finally, a universal scaling functions are good candidates for the data
 collapsing on the same curves, independent of the agents’ quantities.

Gravitational Lensing by Self-Dual Black Holes in Loop Quantum Gravity

description: We study gravitational lensing by a recently proposed black hole solution in Loop Quantum Gravity. We highlight the fact that the quantum gravity corrections to the Schwarzschild metric in this model evade the `mass suppression' effects (that the usual quantum gravity corrections are susceptible to) by virtue of one of the parameters in the model being dimensionless, which is unlike any other quantum gravity motivated parameter. Gravitational lensing in the strong and weak deflection regimes is studied and a sample consistency relation is presented which could serve as a test of this model. We discuss that though the consistency relation for this model is qualitatively similar to what would have been in Brans-Dicke, in general it can be a good discriminator between many alternative theories. Although the observational prospects do not seem to be very optimistic even for a galactic supermassive black hole case, time delay between relativistic images for billion solar mass black holes in other galaxies might be within reach of future relativistic lensing observations.

description: This work introduces hydroelectric power plant optimization method. The paper also includes some background information used for preparation of Hydro-Electric Energy On-line Calculator, as on site: http://www.geocities.ws/nowarski/calculators/Hydro.html The calculator is for general information only; it does not include many components and must not be used for actual design, economic evaluation, or decisions regarding any real project. In addition, the calculator applies Francis turbine efficiency curve formula which is specific for this work and for the calculator and cannot be used for other turbines. The calculator is applied in this work for simulation of the hydroelectric power plant electricity export and for optimization of turbine size. Estimation of amount of electricity which will be generated and exported from hydroelectric plant is the most important step in decision taking process regarding the hydro project. The amount of electricity exported from the hydroelectric plant will be much lower than the nominal power of the turbine considering 24 hours a day and 365 days a year. The optimization using this online calculator allows determination of optimum turbine size for various patterns of the available water flow. The optimization includes energy and economic considerations. From the energy point of view, the aim of the optimization is to find the turbine power which results in highest net electricity export. From the economic point of view, the aim of the optimization is to find the turbine power which results in highest net income. Application of the calculator for simulation and optimization can significantly save investment cost of the project and increase net profit.
