Abstract:

Abstract Porous materials, for example, metalnatural structures (MOFs) and their discrete partners metalnatural polyhedra (MOPs), that are built from coordinatively unsaturated inorganic hubs show incredible potential for application in gas adsorption/partition cycles, catalysis, and arising openings in hardware, optics, detecting, and biotechnology. A well-known hetero-bimetallic metalorganic polyhedra of this discrete partners metalnatural polyhedra (MOPs) class is cuboctahedral bi-metallic stricture. In this paper, we discuss the stricture of Hetero-bimetallic metalorganic polyhedra (cuboctahedral bi-metallic). Also, we computed the topological indices based on the degree of atoms in this cuboctahedral bi-metallic structure.

Abstract:

AbstractOver the past 2 decades, several multi-objective optimizers (MOOs) have been proposed to address the different aspects of multi-objective optimization problems (MOPs). Unfortunately, it has been observed that many of MOOs experiences performance degradation when applied over MOPs having a large number of decision variables and objective functions. Specially, the performance of MOOs rapidly decreases when the number of decision variables and objective functions increases by more than a hundred and three, respectively. To address the challenges caused by such special case of MOPs, some large-scale multi-objective optimization optimizers (L-MuOOs) and large-scale many-objective optimization optimizers (L-MaOOs) have been developed in the literature. Even after vast development in the direction of L-MuOOs and L-MaOOs, the supremacy of these optimizers has not been tested on real-world optimization problems containing a large number of decision variables and objectives such as large-scale many-objective software clustering problems (L-MaSCPs). In this study, the performance of nine L-MuOOs and L-MaOOs (i.e., S3-CMA-ES, LMOSCO, LSMOF, LMEA, IDMOPSO, ADC-MaOO, NSGA-III, H-RVEA, and DREA) is evaluated and compared over five L-MaSCPs in terms of IGD, Hypervolume, and MQ metrics. The experimentation results show that the S3-CMA-ES and LMOSCO perform better compared to the LSMOF, LMEA, IDMOPSO, ADC-MaOO, NSGA-III, H-RVEA, and DREA in most of the cases. The LSMOF, LMEA, IDMOPSO, ADC-MaOO, NSGA-III, and DREA, are the average performer, and H-RVEA is the worst performer.

Abstract:

We hypothesized that modulation of the effective charge density of the endothelial surface layer (ESL) results in altered arterial barrier properties to transport of anionic solutes. Rat mesenteric small arteries (diameter ∼190 μm) were isolated, cannulated, perfused, and superfused with MOPS-buffered physiological salt solutions. MOPS-solutions were of normal ionic strength (162 mM, MOPS), low ionic strength (81 mM, LO-MOPS), or high ionic strength (323 mM, HI-MOPS), to modulate ESL charge density (normal, high, or low ESL charge, respectively). Osmolarity of MOPS, LO-MOPS, and HI-MOPS was kept constant at 297 mosmol/l, using additional glucose when necessary. Perfusate solutions were supplemented with 1% BSA. Arteries were cannulated with a double-barreled theta-pipet on the inlet side and a regular pipet on the outlet side. After infusion of FITC-labeled dextran of 50 kDa (FITC-Δ50) and the endothelial membrane dye 1,1′-dioctadecyl-3,3,3′,3′-tetramethylindocarbocyanine perchlorate, the dynamics of arterial dye filling were determined with confocal microscopy. ESL thickness, as determined from the initial exclusion zone for FITC-Δ50 on the luminal endothelial surface, was 6.3 ± 1.4 μm for LO-MOPS, 2.7 ± 1.0 μm for MOPS, and 1.1 ± 1.3 μm for HI-MOPS. At low ionic strength, FITC-Δ50 permeated into the ESL with a total ESL permeation time (τESL) of 26 min, and at normal ionic strength with a τESL of 20 min. No apparent exclusion of FITC-Δ50 from the ESL could be observed at high ionic strength. In conclusion, we demonstrate that the modulation of solvent ionic strength influences the thickness and barrier properties of the ESL.

Abstract:

Micro-osteoperforations (MOPs) have been reported to accelerate orthodontic tooth movement (OTM), and tumor necrosis factor (TNF)-α has been reported to play a crucial role in OTM. In this report, the influence of MOPs during OTM was analyzed. We evaluated the expression of TNF-α with and without MOPs by RT-PCR analysis. A Ni-Ti closed coil spring was fixed between the maxillary left first molar and the incisors as an OTM mouse model to move the first molar in the mesial direction. MOPs were prepared on the lingual side and mesial side of the upper first molars. Furthermore, to investigate the target cell of TNF-α for osteoclast formation during OTM with MOPs in vivo, we created four types of chimeric mice in which bone marrow of wild-type (WT) or TNF receptor 1- and 2-deficient mice (KO) was transplanted into lethally irradiated WT or KO mice. The results showed that MOPs increased TNF-α expression, the distance of tooth movement and osteoclast formation significantly. Furthermore, mice with TNF-α-responsive stromal cells showed a significant increase in tooth movement and number of osteoclasts by MOPs. We conclude that MOPs increase TNF-α expression, and tooth movement is dependent on TNF-α-responsive stromal cells.

Abstract:

In this report, we explore the use of supercritical CO2 (scCO2) in the synthesis of well-known metal-organic frameworks (MOFs) including Zn-MOF-74 and UiO-66, as well as on the preparation of [Cu24(OH-mBDC)24]n metal-organic polyhedra (MOPs) and two new MOF structures {[Zn2(L1)(DPE)]∙4H2O}n and {[Zn3(L1)3(4,4′-azopy)]∙7.5H2O}n, where BTC = benzene-1,3,5-tricarboxylate, BDC = benzene-1,4-dicarboxylate, L1 = 4-carboxy-phenylene-methyleneamino-4-benzoate, DPE = 1,2-di(4-pyridyl)ethylene, 4.4′-azopy = 4,4′- azopyridine, and compare the results versus traditional solvothermal preparations at low temperatures (i.e., 40 °C). The objective of the work was to see if the same or different products would result from the scCO2 route versus the solvothermal method. We were interested to see which method produced the highest yield, the cleanest product and what types of morphology resulted. While there was no evidence of additional meso- or macroporosity in these MOFs/MOPs nor any significant improvements in product yields through the addition of scCO2 to these systems, it was shown that the use of scCO2 can have an effect on crystallinity, crystal size and morphology.

Abstract:

AbstractThe Missouri Osteochondral Preservation System (MOPS) has been reported to effectively preserve osteochondral allografts (OCAs) twice as long as current tissue bank protocols in preclinical studies. However, viability of OCAs preserved using the MOPS protocol at the time of clinical implantation compared with the current standard of care (SOC) is not known. Viable chondrocyte density (VCD) at time of transplantation will be significantly higher in OCAs preserved using the MOPS protocol compared with OCAs preserved using the current tissue bank protocol and will significantly affect clinical complication rates. Femoral condyle OCAs were obtained from American Association of Tissue Banks accredited tissue banks for clinical use. The OCAs were stored using the current SOC protocol for each respective tissue bank (n = 26) or the MOPS protocol (n = 50). Nonimplanted femoral condyle OCA tissue normally discarded after surgery was collected and assessed for VCD within 1 hour after surgery. Control OCA samples (n = 34) were obtained from one tissue bank. VCD was determined using a validated cell viability assay. Patients (n = 76) had in-clinic follow-up at least 6 months after OCA transplantation. At the time of clinical implantation, mean storage time for OCAs in the SOC cohort was 20.4 days, and in the MOPS cohort was 44.2 days, after procurement. VCD in OCAs in the MOPS cohort was not significantly different from normal healthy cartilage VCD and 100% were above the desired minimum essential level 70% of control VCD at the time of transplantation. VCD in OCAs in the SOC cohort was significantly (p < 0.001) lower than controls and MOPS, and only 27% were above 70% of control VCD at the time of transplantation. MOPS preserves OCA chondrocyte viability at significantly higher levels than current tissue bank storage protocols for a longer period of time after procurement. All MOPS-preserved OCAs exceeded minimum essential VCD levels for up to 56 days after procurement.

Abstract:

Objective. This paper examines the effects of various measures of performance (MOP) selections on simulation model calibration performance, in terms of reflecting actual traffic conditions and vehicle interactions. Method. Two intersections in Shanghai were selected for simulation model calibration, one for testing and another for validation. Three effective MOPs were utilized, including average travel time (i.e., time passing the intersection), average queue length, and vehicle headway distribution. The counts of three types of traffic conflicts (i.e., crossing, rear-end, and lane change) were used as safety MOPs. Those MOPs, as calibration objectives, were examined and compared. Results. The results of the testing site showed that different effective MOPs had their own advantages: average travel time appeared to be the best in reflecting lane change and rear-end conflicts while headway distribution performed the best consistency between simulated and actual crossing conflicts. Compared to the safety MOPs, average travel time and headway distribution still performed better, in terms of resulting in more similar simulated conflict metrics (e.g., TTC, PET) to actual ones. A multicriteria calibration strategy based on average travel time and headway distribution generally had better performances in reflecting actual traffic conditions and vehicle interactions than using any single effective or safety MOP. Similar results were found for the validation site. Conclusion. To simulate actual traffic conditions and vehicle interactions, multiple effective MOPs could be simultaneously considered for model calibration, instead of using safety MOPs.

Abstract:

Introduction. The differential management of anchorage and the acceleration of tooth movement are some of the current greatest challenges for orthodontists. Diverse techniques and devices to reinforce anchorage and increase the rate of tooth movement have been proposed. Whether micro-osteoperforations (MOPs) can be used for both purposes is currently investigated. Objectives. To propose and describe a new technique for biological anchorage, which involves six MOPs performed every four weeks, and to present its results in a clinical case of upper premolar extraction. Intervention. In a dental class II patient who met the selection criteria, three MOPs both on the buccal and palatine sides on the intervention side were performed on the extraction area following the protocol described. No MOPs were performed on the control side. The allocation of the intervention was randomised. The MOPs were performed three times at an interval of four weeks. A 0.019 × 0.025 -inch stainless steel wire was activated with calibrated NiTi springs. The three-dimensional movement of the first molars and upper canines was evaluated. In addition, the comfort, periodontal status, and canine root resorption of the patient were evaluated. Results. Clinical and radiographic results suggest that the MOPs had a positive effect in reducing the loss of biological anchorage of the posterior sector and in the rate of canine tooth movement, without damaging changes in the soft and hard tissues. Conclusion. The proposed protocol involving six MOPs every four weeks improved the behaviour of biological anchorage and increased distalization on the intervention side in this clinical case.

Abstract:

Varicoceles (VCs) are the predominant cause of male infertility and are a risk factor for chronic venous disease.Morinda officinalis(M. officinalis) is a traditional Chinese medicine used to tonify the kidney and strengthen yang. In this study, we evaluated the effects of water-soluble polysaccharides extracted fromM. officinalis(MOPs) on gonadotropin-release hormone (GnRH) secretion in a classic experimental left VC (ELV) rat model. Intragastric administration of MOPs at a dose ranging from 50 mg kg−1to 100 mg kg−1facilitated improvements in sperm parameters and seminiferous epithelial structures, modulated serum hormone profiles, and stimulated GnRH synthesis and release in the hypothalamus. MOPs also promoted spinogenesis and functional spine maturation in the arcuate nuclei (Arc), wherein they acted mainly on Kiss1 and GnRH neurons. Moreover, MOP-mediated Kisspeptin-GPR54 pathway upregulation and MAPK phosphorylation activation may have been responsible for increases in GnRH synthesis and release. Collectively, the findings of this study indicate that MOPs were effective in stimulating GnRH secretion, possibly by upregulating the Kiss1/GPR54 pathway and enhancing synaptic plasticity, and that MOPs can serve as a therapy for early VCs.

Abstract:

Background: Fresh osteochondral allografts (OCAs) are limited in availability. The Missouri Osteochondral Allograft Preservation System (MOPS) has been reported to effectively preserve OCAs twice as long as current tissue bank protocols in preclinical studies. Hypothesis: The viable chondrocyte density (VCD) in OCAs preserved for up to 70 days using the MOPS will not be significantly different from day 0, and the VCD in MOPS-preserved OCAs will be significantly higher than for standard tissue bank preservation. Media changes during preservation will significantly improve the VCD. Study Design: Controlled laboratory study. Methods: Femoral condyles harvested from qualified donors (n = 12) were quartered (n = 48), assigned to 1 of 4 treatment groups (tissue bank protocol at 4°C or MOPS at 25°C, with or without media changes), and preserved for 0, 28, 56, or 70 days and assessed for the VCD and histopathological characteristics. In addition, osteochondral explants were created from the femoral condyles of 12 donors (n = 36 explants), assigned to the same groups and time points, and tested for biomechanical properties. Results: MOPS-preserved OCAs maintained the day 0 VCD through 56 days. OCAs stored using current tissue bank protocols had a significantly lower VCD compared with day 0 and the MOPS by day 28. OCA histological and biomechanical properties did not significantly change from day 0 for any group. Conclusion: The MOPS preserved essential OCA viability and quality at significantly higher levels than current tissue bank protocols for at least 56 days after procurement. Clinical Relevance: Improving the viability and duration of OCA preservation provides potential benefits to tissue banks, donor families, surgeons, and patients with respect to tissue use, financial costs, and outcomes.

Full text

Abstract:

Using single-electrode current-clamp and two-electrode voltage-clamp, different identified neurones of the leech (Hirudo medicinalis L.) were shown to hyperpolarize, or to exhibit outward currents (usually >2 nA), during bath application of the organic buffers Mops, Pipes and Mes (10 mmol l-1). Tris and Hepes had little or no effect on the membrane properties of neurones when they were added to a bathing saline buffered by CO2-HCO3- at a constant pH of 7.4. Outward currents evoked by buffers obtained from two suppliers, Roth and Sigma, were not significantly different, except in the case of Pipes. Steady-state currents evoked by Pipes supplied by Roth were eightfold larger than steady-state currents evoked by Pipes from Sigma. A transient current peak always present in responses evoked by Pipes from Roth was never present in responses evoked by Pipes from Sigma. Outward currents evoked by buffers were due to a conductance increase and appeared to be carried by Cl-. In low-Cl- saline, hyperpolarizations evoked by Mops in Retzius cells were reduced. When Cl- was injected into heart motor neurones, the hyperpolarizations evoked by Mops reversed. Tetraethylammonium (TEA+) injected into heart interneurones did not block Mops-evoked hyperpolarizations. Mops-evoked outward currents in Retzius cells were partially blocked by d-tubocurarine and bicuculline methiodide, and the latter also partially blocked Mops-evoked hyperpolarizations in HE cells. Since d-tubocurarine partially blocked acetylcholine-evoked Cl- currents in Retzius cells and bicuculline methiodide partially blocked carbachol-evoked hyperpolarizations in HE cells, Mops appears to act on the cholinergic receptors of these neurones by mediating a Cl- conductance.

Abstract:

Malformations of teeth and dental arches can produce functional modifications intermingled with esthetic alterations. Children’s rehabilitation may be long, requiring multiple interventions. One of the main challenges of contemporary orthodontics is to reduce treatment time by accelerating orthodontic tooth movements. Among the currently used methods, micro-osteoperforations (MOPs) are flapless, minimally invasive perforations that induce a local trauma to the bone, increase healing capacity, and accelerate dental movements. The use of MOPs in orthodontics is spreading but there are no definite and recognized protocols for their application. This scoping review collected the available evidence in the effect of MOPs during orthodontic therapy as compared to current treatments, to summarize the evidence. The guidelines proposed by PRISMA-ScR were followed: original clinical studies carried out from 2010 to 2021 were retrieved by medical databases combining the terms “micro-osteoperforations” and “accelerated orthodontic tooth movement”. From a total of 965 articles, nine were finally selected. The studies’ aims, designs, methods, measurements, outcomes, and main findings were very heterogenous, with a duration ranging from 4 weeks to 7 months. This included only Class I malocclusion to any malocclusion. It assessed the effects of MOPs coupled with a variety of orthodontic mechanics on either the retraction of maxillary canines, the distalization of maxillary molars, or the modifications on premolar roots. Mostly, variations in the number, location, and timing of MOPs impeded a global assessment. Overall, most of the studies (six out of nine) reported moderately useful effects of MOPs, one was negative, and only two found significant advantages of MOPs over conventional treatment. The review synthesized the available evidence about MOP applications in orthodontics and identified some important gaps in knowledge that could be starting points for a systematic review of the literature. In conclusion, even if MOPs can accelerate tooth movements, the variety of aims and methods of the published research prevents suggestion of their widespread use.

Abstract:

The objective of this study was to optimize bovine sperm storage for up to 20 h between semen collection and sex sorting followedby cryopreservation. Two successive ejaculates were obtained from mature dairy bulls (Holstein, n = 5; Jersey, n = 3) via artificial vagina. Treatments were then applied to the neat semen to which antibiotics were added as recommended by Certified Semen Services (Columbia, MO). Nothing further was added to the control samples until staining with Hoechst 33342 for sorting. For Treatment 1, semen was diluted 9:1 with a MOPS solution resulting in 24 mM MOPS and similarly, Treatment 2 resulted in 24 mM MOPS +2% egg yolk. A subsample of each treatment and control was sorted by flow cytometry shortly after collection, and sperm then were frozen following standard processing procedures. The other subsample was stored at 15-18°C and sorted 20 h after collection followed by cryopreservation. pH measurements were made before staining samples for sorting. Samples were evaluated post-thaw for subjective progressive and total sperm motility, by computer-assisted sperm analysis (CASA, Berkeley, CA, USA), and by flow cytometry for sperm viability using propidium iodide and SYBR-14. Treatment 1 performed better than the control (Table 1), while results for Treatment 2 were similar to the control. Second ejaculates were superior to first ejaculates. pH measurements showed that addition of MOPS kept the pH about 0.2 units higher than the control, but pH declined similarly over time in all groups. While responses for the 20 h sort were numerically lower than the 0 h sort (P > 0.1), the majority of responses were acceptable for most, but not all bulls. In conclusion, storing sperm in 24 mM MOPS was beneficial. Surprisingly, 2% egg yolk negated the beneficial effect of MOPS, possibly due to increasing osmolarity by ∼15mOsM/kg due to pH adjustment. Addition of MOPS provided better results than the control for both the 0 h and 20 h sorts. Table 1.Main effect means of semen characteristics

Abstract:

Multi-objective swarm intelligence (MOSI) metaheuristics were proposed to solve multi-objective optimization problems (MOPs) that consists of two or more conflict objectives, in which improving an objective leads to the degradation of the other. The MOSI algorithms are based on the integration of single objective algorithms and multi-objective optimization (MOO) approach. The MOO approaches include scalarization, Pareto dominance, decomposition and indicator-based. In this paper, the status of MOO research and state-of-the-art MOSI algorithms namely, multi-objective particle swarm, artificial bee colony, firefly algorithm, bat algorithm, gravitational search algorithm, grey wolf optimizer, bacterial foraging and moth-flame optimization algorithms have been reviewed. These reviewed algorithms were mainly developed to solve continuous MOPs. The review is based on how the algorithms deal with objective functions using MOO approaches, the benchmark MOPs used in the evaluation and performance metrics. Furthermore, it describes the advantages and disadvantages of each MOO approach and provides some possible future research directions in this area. The results show that several MOO approaches have not been used in most of the proposed MOSI algorithms. Integrating other different MOO approaches may help in developing more effective optimization algorithms, especially in solving complex MOPs. Furthermore, most of the MOSI algorithms have been evaluated using MOPs with two objectives, which clarifies open issues in this research area.

Abstract:

AIM: The aim of the study was to investigate the effectiveness of using micro-osteoperforations (MOPs) or piezocision in accelerating tooth movement, during canine retraction, compared to standard canine retraction. PATIENTS AND METHODS: A split-mouth study design was carried out with two Groups A and B. Each group contained 10 patients; in each patient, one side was used as a control side and the contralateral side received either MOPs (Group A) or piezocision (Group B). The assessment data were collected by direct intraoral measurements, every 2 weeks, over a 3 months retraction period. RESULTS: Independent t-test, paired t-test, and ANOVA were used to analyze the results. In Group A, there was a statistically significant difference between the study and control sides (p < 0.001) with a total of 4.2 ± 0.5 mm canine retraction in the MOPs assisted canine retraction side versus a 2.8 ± 0.2 mm total canine retraction in the control side. For Group B, there was a statistically significant difference between the study and control sides (p < 0.001) with a total of 3.6 ± 0.4 mm canine retraction in the piezocision-assisted canine retraction side versus a 2.8 ± 0.2 mm total canine retraction in the control. CONCLUSION: MOPs and piezocision techniques accelerated the rate of canine retraction during orthodontic treatment, with the MOPs being slightly more effective.

Abstract:

Multi-objective optimization problems (MOPs) have been widely studied during the last decades. In this paper, we present a new approach based on Chaotic search to solve MOPs. Various Tchebychev scalarization strategies have been investigated. Moreover, a comparison with state of the art algorithms on different well known bound constrained benchmarks shows the efficiency and the effectiveness of the proposed Chaotic search approach.

Abstract:

Problems where several incommensurable objectives have to be optimized concurrently arise in many engineering and financial applications. Continuation methods for the treatment of such multi-objective optimization methods (MOPs) are very efficient if all objectives are continuous since in that case one can expect that the solution set forms at least locally a manifold. Recently, the Pareto Tracer (PT) has been proposed, which is such a multi-objective continuation method. While the method works reliably for MOPs with box and equality constraints, no strategy has been proposed yet to adequately treat general inequalities, which we address in this work. We formulate the extension of the PT and present numerical results on some selected benchmark problems. The results indicate that the new method can indeed handle general MOPs, which greatly enhances its applicability.

Abstract:

AIM: The study was conducted to evaluate the effect of combined low energy laser application and Micro-Osteoperforations versus the effect of the application of each technique separately on the rate of orthodontic tooth movement. PATIENTS AND METHODS: Three parallel groups (each group contained 10 patients) were performed; Group A: In which one side was controlled side, and the other side received micro-osteoperforations (MOPs), Group B: In which one side was controlled side, and the other side received low-level laser therapy (LLLT), Group C: In which one side was controlled side, and the other side received both MOPs and LLLT. RESULTS: Significant statistical differences were obvious in the rate of canine retraction between each intervention and the control sides as following; the MOPs increased the rate of canine retraction by 1.6 fold more than the control side, LLLT increased the rate of canine retraction by 1.3 fold than the control side, and combination of both techniques resulted in an increase in the rate of canine retraction by 1.8 fold more than the control side. CONCLUSION: Combination of MOPs and LLLT proved to be more efficient regarding increasing the rate of canine retraction than the application of each technique separately.

Abstract:

This corrosion study assessed the inhibition performance of carbon steel in 1 M of hydrochloric acid (HCl) using Good’s buffer ionic liquids (GBIL) namely 1-Butyl-3-methylimidazolium 2-(N-Morpholino) propane, [BMIM][MOPS] using electrochemical impedance, potentiodynamic polarization, and weight loss (gravimetric) measurements. GBIL are synthesized by the combination of Good's buffer as anion and various organic bases as the cation. The gravimetric measurements exhibit higher reduction in weight for carbon steel exposed to the acidic environment in the absence of corrosion inhibitor (CI) as compared to carbon steel immersed in the presence of inhibitor molecule. Potentiodynamic polarization study indicates that the synthesized inhibitor acted as a mixed type inhibitor. The inhibition efficiency increases with increase in the concentration of [BMIM][MOPS]. Corrosion protection efficiency ranging from 88% to 90% was featured at 800 ppm of CI in the HCl medium. The adsorption of [BMIM][MOPS] on the carbon steel surface was described by the Langmuir's adsorption isotherm. The scanning electron micrographs inspected the morphology of the carbon steel surface exposed to the solution without and with the presence of inhibitor. The result showed that compound effectively suppressed corrosion by the appearance of an improved surface structure of carbon steel with increasing concentration of [BMIM][MOPS].

Abstract:

Multi-Objective Problems (MOPs) are common real-life problems that can be found in different fields, such as bioinformatics and scheduling. Pareto Optimization (PO) is a popular method for solving MOPs, which optimizes all objectives simultaneously. It provides an effective way to evaluate the quality of multi-objective solutions. Swarm Intelligence (SI) methods are population-based methods that generate multiple solutions to the problem, providing SI methods suitable for MOP solutions. SI methods have certain drawbacks when applied to MOPs, such as swarm leader selection and obtaining evenly distributed solutions over solution space. Whale Optimization Algorithm (WOA) is a recent SI method. In this paper, we propose combining WOA with Tabu Search (TS) for MOPs (MOWOATS). MOWOATS uses TS to store non-dominated solutions in elite lists to guide swarm members, which overcomes the swarm leader selection problem. MOWOATS employs crossover in both intensification and diversification phases to improve diversity of the population. MOWOATS proposes a new diversification step to eliminate the need for local search methods. MOWOATS has been tested over different benchmark multi-objective test functions, such as CEC2009, ZDT, and DTLZ. Results present the efficiency of MOWOATS in finding solutions near Pareto front and evenly distributed over solution space.
