The paper investigates the reproduction accuracy of Ricoh Aficio colour 3006 printer. The study has been conducted analyzing four-color (CMYK) gradation curves – the compliance of zonal absorbance with standard references and printing stability of gradation scales. The obtained colours have been measured spectrophotometrically determining the coordinates of colours CIE L*a*b* and differences in colours ΔE. Eight printing regimes and their settings have been examined. It has been found that the printer Ricoh has inaccurately colour grading. However, the quality of colour reproduction is sufficient for printing data not requiring high accuracy of colour reproduction. Colour grading significantly differs from the theoretical approaches, though some regimes (Gamma, Brightness, CMYK simulation) allows achieving theoretical values. Despite the high inaccuracy of gradation, differences in colour are not high enough due to corrections made by software. keywords: Ricoh Afficio 3006, colour gamut, reproduction, colour space
Sensitivity Analysis on Regime-Switching Models by Wiener-Malliavin Calculus

In this paper we present the sensitivity analysis on regime switching models applying the techniques of Malliavin calculus. As is well known, risk management in portfolio pricing and hedging is often achieved by estimating the Greeks, which are price sensitivities relative to variations in the model parameters. By developing this method for sensitivity analysis, we have multiple versions of Greeks expression, optimization by minimizing the variance of weight is available among those alternatives. Although the classical Malliavin calculus approach requires the differentiability of the payoff function, we extend the results for models with non-differentiable payoff function.

Effect of HVO CNG dual-fuel operation mode on emissions and performance of CI engine

The presented paper aimed to investigate the base effect of the application of HVO (hydrotreated vegetable oil) and CNG (compressed natural gas) and their mixtures as a fuel in the CI (compression ignition) engine. Both fuels were then used in the dual-fuel operating mode (HVO-CNG). Dual-fuel applications are usually made with a liquid fuel (diesel) pilot dose and gaseous fuel (LPG, CNG etc.) main dose. In times of reducing greenhouse emission gases and reducing the dependency on Russian gas and oil, it should be possible and technically possible to reduce both of them in several engine machine applications. As an ecological substitute for diesel oil hydrotreated vegetable oil is used and as an ecological substitute for compressed natural gas biomethane should be used. All experiments were done on a four-stroke direct injection turbocharged CI engine with an installed AC STAG electronic control unit and system for the dual-fuel operating mode. The whole setup was installed on a test bed equipped with ac dyno (which also allows running transient tests) and with other external measurement devices. For the high-pressure indicating parameters, AVL X-ion was used (with an Indicom SW). Horiba mexa-one device was used for gaseous emission measurement. For particulate matter measuring, Horiba SPCS counter was used and Horiba MDLT-One dilution tunnel and TSI EEPS as the particle sizer. As a base level, parameters were set and used for performance and other parameters (emissions, burning, knocking etc.) from the diesel operating mode. All other operating modes were then compared to the base level.
Insurance fraud as a form of economic crime and the methods for combating it

Dealing with the topic of economic crime in insurance is very complex and therefore challenging. One of the first challenges concerns the definition of economic crime. Namely, economic crime represents a multi-layered phenomenon which must, in terms of the definition of the basic features, be adapted to the specific requirements of a given society. One of the forms of economic crime, which is very common in practice, certainly refers to abuse in the field of insurance. The most common, and at the same time the only form of economic crime in the field of insurance foreseen by law, is insurance fraud. After the conceptual determination of economic crime as well as its basic features, this paper presents a review of the key issues related to the topic of the paper, which includes the phenomenological definition of insurance, the importance of the existence of insurance, insurance fraud as a form of economic crime, as well as the methods for combating it.
Evaluation of the Synergistic Effect of Azadirachta indica-based Silver Nanoparticles in Combination with Antibiotics and Hypoglycemic Drugs: In vitro Antimicrobial and In vivo Antidiabetic Activities

This study was conducted to evaluate the synergistic effects of the mixtures of green silver nanoparticles (AgNPs) with ampicillin and metformin separately in obviating the global threats of antimicrobial resistance and diabetes mellitus. AgNPs was synthesized using Azadirachta indica aqueous leaf extract at varying extract concentration and incubation time. The synthesis of AgNPs in aqueous solution was confirmed by the visual color change and by using a UV-Vis spectrophotometer. The biosynthesized AgNPs was further characterized using Scanning Electron Microscope (SEM) analysis. The experimental results revealed that the biosynthesized AgNPs were polydispersed, smaller in size and aggregated. The mean diameter of the formed AgNPs was 50 nm as evident from the SEM analysis. Additionally, the mixtures of AgNPs with ampicillin and metformin exhibited synergistic in vitro antimicrobial and in vivo antidiabetic effects i.e., being more efficacious than AgNPs, ampicillin and metformin alone.

A Novel Concatenation Decoding of Reed-Solomon Codes With SPC Product Codes

This letter introduces a novel concatenation decoding of Reed-Solomon (RS) codes with single parity-check product codes (SPC-PCs), including the concatenation scheme and the decoding algorithm. The proposed scheme sequentially arranges SPC-PCs to form <inline-formula><tex-math notation="LaTeX">$K$</tex-math></inline-formula> information symbols, then encodes them into <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula> symbols using systematic RS code. A high-performance and low-complexity bit-iterative-update decoding (BIUD) algorithm is also proposed based on this scheme. We use the results of the parity-check to evaluate the reliability in each dimension and then iteratively update the reliability of each bit based on the structure of SPC-PCs. This way dramatically reduces the complexity of traditional reliability computation. Furthermore, the bit iterative update and the Berlekamp-Massey algorithm of RS codes can be well combined, resulting in more accurate results. The simulation and analysis results show that the proposed concatenation algorithm has significant performance improvement compared to the current RS-SPC concatenation decoding while having extremely low complexity.
End-to-end Multimodal Emotion and Gender Recognition with Dynamic Weights of Joint Loss

Multi-task learning (MTL) is one of the method for improving generalizability of multiple tasks. In order to perform multiple classification tasks with one neural network model, the losses of each task should be combined. Previous studies have mostly focused on prediction of multiple tasks using joint loss with static weights for training model. Choosing weights between tasks have not taken any considerations while it is set by uniformly or empirically. In this study, we propose a method to make joint loss using dynamic weights to improve total performance not an individual performance of tasks, and apply this method to end-to-end multimodal emotion and gender recognition model using audio and video data. This approach provides proper weights for each loss of the tasks when training ends. In our experiment, a performance of emotion and gender recognition with proposed method shows lower joint loss which is computed as negative log-likelihood than the one with static weights of joint loss. Also, our proposed model shows better generalizability than compared models. In our best knowledge, this research shows the strength of dynamic weights of joint loss for maximizing total performance at first in emotion and gender recognition task.
Gut Bacteria of Snakeheads of Chinadi Beel, Narsingdi and Their Antibiogram Profile

The gut bacteria of snakehead fish (Channa punctata, C. marulius and C. striata) collected from Chinadi beel, Narsingdi, Bangladesh was characterized and formulated their antibiogram profile. The mean richness of intestinal bacteria in C. punctata was significantly higher in comparison to C. marulius and C. striata. A total of 24 isolates under the genus Bacillus, Enterobacter, Citrobacter, Kluyvera, Vibrio, Pseudomonas and Acinetobacter were identified. The strains of Enterobacter and Pseudomonas showed 100% resistance to eight antibiotics. The isolates of C. punctata were found to be resistant to nine antibiotics followed by C. marulius (8) and C. striata (7) indicating a critical condition of Chinadi beel of being polluted by anthropogenic activities.

Pacific-North American Teleconnection Tumbles Snowfall Records West of the Cascades during Christmas Week 2021

During Christmas week 2021, winter storms pummeled the Pacific Northwest and broke daily temperature and snowfall records in scores, especially west of the Cascades and notably in Oregon. With La Niña ruling the tropical Pacific, the record-setting, disruptive snowfall during Christmas week raised questions about its origin, especially as the seasonal outlook was for below-normal precipitation. We show that Pacific-North American teleconnection – a well-documented subseasonal variability pattern during winter – reigned over the region in its negative phase; it was the strongest 7-day PNA episode in December in more than 50 years. It led to robust northwesterly onshore flow, whose interaction with the Coastal, Cascade, and Sierra ranges led to blockbuster snowfall and precipitation. Note that one seldom encounters circulation anomalies consisting of just one winter teleconnection pattern. Also worth noting is the tremendous power of subseasonal variability in recharging Western water resources in the context of the seasonal gloom from a La Niña-intensified West Coast drought.
Feeding Effect of Organic and Inorganic Zinc with Vitamin E on Growth Performance and Carcass Quality of Japanese Quail

The research facility of Avian Research & Training (ART) Center (Poultry Production), UVAS, Lahore was selected to investigate the effect of feeding organic and inorganic zinc in addition to vit-E on the growth performance of Japanese quail. for a period of 6 months. The diet formulated by the inclusion of ZnO + ZnI (mg)+VE(IU) as 0+0+0 (A), 25+0+0 (B), 0+15+0 (C), 0+0+12 (D), 25+15+0 (E), 25+0+12 (F), 0+15+12 (G) and 25+15+12 (H), respectively. The effect of zinc and vit-E on growth and slaughter traits of Japanese quail was significant (P<0.05) and it was perceived that in 6 weeks the broiler quails in groups H and F took higher feed (745.44 and 734.70 g/bird), with simultaneous effect on LBW of males (175.35 and 174.50 g), females (198.35 and 197.38 g), average (186.85 and 185.94 g), intestine filled (6.81 and 6.66 g) and empty weights (5.51 and 4.88 g), intestine length (44.87 and 44.75 g), cecal length (16.37 and 16.12 cm), the weight of carcass + giblets (142.01 and 141.48 g), carcass (130.88 and 130.25 g), heart (2.18 and 2.16 g), liver (5.02 and 5.06 g), gizzard (5.62 and 5.21 g), respectively. The dietary Zn + vit-E inclusion significantly (P<0.05) increased the relative length of gut segments, villi height, villus thickness, the villi height to crypt depth proportion in jejunum and ileum and the number of goblet cells in various parts of the intestine of quails. The meat production was significantly higher in female quails than the meat of male quails. This suggested that the organic Zn proved to be better than the inorganic Zn source in addition to vit-E to achieve physiology-related traits in quails.
Insight Into the Laboratory Diagnosis of Periimplantitis Using Reactive Oxygen Metabolite Levels - A Biochemical Study

Aim The study aims to substantiate the quantitative role of the predominant periodontopathogen (Porphyromonas gingivalis) associated with peri-implantitis and evaluate the reactive oxygen metabolite levels in peri-implantitis patients. Methodology A total of 40 participants were taken from the department of periodontology, Thai Moogambigai Dental College and Hospital, Chennai, and divided into groups I (control) and II (test). Group I included 20 participants with healthy peri-implant tissue, and group II included 20 participants with infected peri-implant tissues. The predominant periodontopathogen was detected by using a quantitative real-time polymerase chain reaction. Samples (gingival crevicular fluid (GCF), saliva, and plasma) were collected, and a biochemical assay was conducted for reactive oxygen metabolites (ROM) analysis in healthy implants (control group) and peri-implantitis conditions (test group). ROM levels of the patients were statistically analyzed. Results The qualitative and quantitative profiles of Porphyromonas gingivalis (P. gingivalis) associated with Peri-implantitis were analyzed, and the levels of ROM in periimplantitis patients were assessed. The study results substantiate the quantitative picture of Porphyromonas gingivalis in the detection of periimplantitis. The saliva and GCF samples showed significant differences in ROM levels between the test and control groups. Conclusion This is one of the few studies to detect the predominant bacterial pathogen associated with peri-implantitis and assess the ROM levels in periimplantitis patients. The study gives a correlation between the periopathogens and ROM levels, thereby facilitating the attainment of the best possible treatment options.
Assessment of Two Methods for Predicting Soil Retention Relationship from Basic Soil Properties

The purpose of this study was to develop the best transfer functions for estimating the soil water retention curve (SWRC) for Iraqi soils using multiple regression methods. Soil samples were collected from 30 different sites in Iraq at two depths (0–0.3 m and 0.3–0.6 m) to create a database for the development of predictive transfer functions. The database included information on soil particle size distribution, carbonate minerals, mass density, particle density, organic matter, saturated hydraulic conductivity, capillary height, and available water limits. Ex-planatory variables (EV) were the measured characteristics, while response variables (RV) were the volumetric water content measured at different potentials (0, 5, 10, 33, 500, 1000, 1500 kPa). Two methods were used to de - velop predictive transfer functions: the logit model and beta model. Prediction accuracy was assessed using mean bias error (MBE), mean absolute error (MAE), root mean square error (RMSE), and coefficient of determination (R2). The results showed that the variables included in the derivation of the two models for predicting θ ( Ψ ) were similar, except at θ (0). The variables w1 (w1 = 2P
Mosaic Genome of a British Cider Yeast

Hybrid formation and introgressions had a profound impact on fermentative yeasts domesticated for beer, wine and cider fermentations. Here we provide a comparative genomic analysis of a British cider yeast isolate (E1) and characterize its fermentation properties. E1 has a Saccharomyces uvarum genome into which ~102 kb of S. eubayanus DNA were introgressed that replaced the endogenous homologous 55 genes of chromosome XIV between YNL182C and YNL239W. Sequence analyses indicated that the DNA donor was either a lager yeast or a yet unidentified S. eubayanus ancestor. Interestingly, a second introgression event added ~66 kb of DNA from Torulaspora microellipsoides to the left telomere of SuCHRX. This region bears high similarity with the previously described region C introgression in the wine yeast EC1118. Within this region FOT1 and FOT2 encode two oligopeptide transporters that promote improved nitrogen uptake from grape must in E1, as was reported for EC1118. Comparative laboratory scale grape must fermentations between the E1 and EC1118 indicated beneficial traits of faster consumption of total sugars and higher glycerol production but low acetic acid and reduced ethanol content. Importantly, the cider yeast strain produced high levels of fruity ester, including phenylethyl and isoamyl acetate.
Objective assessment of the variation in number of doses of generic timolol eye drops along with their cost effectiveness.

First, this study aims to ascertain if truly the generic timolol eye drops circulating in Abuja and it environ are interchangeable. Secondly, we explore their cost effectiveness in naira based on the dispensing position. Using official guidelines, we assessed seven generic timolol ophthalmic preparations for organoleptic, pH, viscosity, sterility, and assay test. After this, they were tested in the vertical (90 ⁰) and horizontal (30 ⁰) positions for filled volume in a bottle, the total number of drops per bottle, drops per mL; and eventually the total number of bottles needed per year, cost per year and their cost effectiveness per mmHg were extrapolated. All brands were colorless and devoid of particulate contamination. Assay, pH, and viscosity values were within the compendia specification (BP and USP) for eye drops. The sterility assay showed no evidence of bacterial or fungi growth. All brands had actual filled volume less than or equal to the stated label claim. Their drops per 5 mL bottle range from 141-169 and 122-139 when dispensed in vertical and horizontal positions respectively; while for brands with 10 mL label volume, they range from 305-321 and 299-309 drops per bottle for vertical and horizontal dispensing respectively. Brand T1 (which is the most expensive) would need two bottles less in a year if the medication were to be dispensed vertically, amounting to N 3,200.00 ($ 7.04) reduction in treatment cost and a 45 % improvement in cost-effectiveness per intraocular pressure (IOP) reduction per year. In conclusion, the dispensing technique played a significant role in the number of drops per bottle, this would however impact on the treatment cost of glaucoma patient placed on timolol eye drop.
Innovative Strategies in Microvascular Head and Neck Reconstruction

The field of reconstructive microsurgery has witnessed considerable advancements over the years, driven by improvements in technology, imaging, surgical instruments, increased understanding of perforator anatomy, and experience with microsurgery. However, within the subset of microvascular head and neck reconstruction, novel strategies are needed to improve and optimize both patient aesthetics and post-operative function. Given the disfiguring defects that are encountered following trauma or oncologic resections, the reconstructive microsurgeon must always aim to innovate new approaches, reject historic premises, and challenge established paradigms to further achieve improvement in both aesthetic and functional outcomes. The authors aim to provide an up-to-date review of innovations in head and neck reconstruction for oncologic defects.
Retrograde waves in tropical cyclone inner-core

This study presents an extension of Kelvin's vortex wave model for the inner-core region of tropical cyclone-like vortices. By considering a more suitable approximation for tropical cyclones (TCs) for which the horizontal scale of the TC inner-core is significantly larger than the TC vertical depth and taking into account the TC inherent baroclinicity, it is shown that there exists a retrograde wave mode in which the wave propagation is opposite to the mean tangential flow for the azimuthal wavenumber 1. While this result appears to be similar to that obtained in Kelvin's wave model, the retrograde mode in the TC-like vortices depends critically on the TC baroclinicity that Kelvin's model does not contain. Idealised simulations of a TC-like vortex using the full-physics Hurricane Weather Research and Forecasting (HWRF) model indeed capture existence of the retrograde waves inside the vortex inner-core at the high intensity limit. Despite the brief existence of this retrograde mode, the emergence of retrograde waves in the HWRF simulations is of significance, because they may be related to subsequent wave growth and formation of mesovortices that are often observed inside the core region of intense TCs.
