Simplicial cascades are orchestrated by the multidimensional geometry of neuronal complexes
Authors: Kilic Bengier Ülgen , Taylor Dane
Published: November 2022

Cascades over networks (e.g., neuronal avalanches, social contagions, and system failures) often involve higher-order dependencies, yet theory development has largely focused on pairwise-interaction models. Here, we develop a ‘simplicial threshold model’ (STM) for cascades over simplicial complexes that encode dyadic, triadic and higher-order interactions. Focusing on small-world models containing both short- and long-range k-simplices, we explore spatio-temporal patterns that manifest as a frustration between local and nonlocal propagations. We show that higher-order interactions and nonlinear thresholding coordinate to robustly guide cascades along a k-dimensional generalization of paths that we call ‘geometrical channels’. We also find this coordination to enhance the diversity and efficiency of cascades over a simplicial-complex model for a neuronal network, or ‘neuronal complex’. We support these findings with bifurcation theory and data-driven approaches based on latent geometry. Our findings provide fruitful directions for uncovering the multiscale, multidimensional mechanisms that orchestrate the spatio-temporal patterns of nonlinear cascades.

What Is Clinical Evidence in Speech-Language Pathology? A Scoping Review
Authors: Fissel Brannick Schea , Wolford George W. , Wolford Laura L. , Effron Kayleigh , Buckler Jennifer
Published: November 2022

Purpose:

Two disparate models drive American speech-language pathologists' views of evidence-based practice (EBP): the American Speech-Language-Hearing Association's (2004a, 2004b) and Dollaghan's (2007). These models discuss evidence derived from clinical practice but differ in the terms used, the definitions, and discussions of its role. These concepts, which we unify as
clinical evidence
, are an important part of EBP but lack consistent terminology and clear definitions in the literature. Our objective was to identify how clinical evidence is described in the field.

Method:

We conducted a scoping review to identify terms ascribed to clinical evidence and their descriptions. We searched the peer-reviewed, accessible, speech-language pathology intervention literature from 2005 to 2020. We extracted the terms and descriptions, from which three types of clinical evidence arose. We then used an open-coding framework to categorize positive and negative descriptions of clinical expertise and summarize the role of clinical evidence in decision making.

Results:

Seventy-eight articles included a description of clinical evidence. Across publications, a single term was used to describe disparate concepts, and the same concept was given different terms, yet the concepts that authors described clustered into three categories:
clinical opinion, clinical expertise,
and
practice-based evidence,
with each described as distinct from research evidence, and separate from the process of clinical decision making. Clinical opinion and clinical expertise were intrinsic to the clinician. Clinical opinion was insufficient and biased, whereas clinical expertise was a positive multidimensional construct. Practice-based evidence was extrinsic to the clinician—the local clinical data that clinicians generated. Good clinical decisions integrated multiple sources of evidence.

Conclusions:

These results outline a shared language for SLPs to discuss their clinical evidence with researchers, families, allied professionals, and each other. Clarification of the terminology, associated definitions, and the contributions of clinical evidence to good clinical decision-making informs EBP models in speech-language pathology.

A bi‐layer stochastic coordinated planning framework for wind‐battery power systems considering bilateral carbon trading
Authors: Nan Junpei , Feng Jieran , Deng Xu , Wang Chao , Sun Ke , Zhou Hao
Published: November 2022

Renewable energy and energy storage are essential technologies for decarbonizing energy systems. Expansion planning of the two technologies considering source‐side carbon responsibility has been well studied. However, expansion planning considering both source‐side and load‐side carbon responsibility, which may simultaneously stimulate the carbon reduction potential of source and load, has been rarely studied. To fill this research gap, this paper proposes a bi‐layer wind turbine generator (WTG) and demand‐side battery (DSB) coordinated planning framework considering wind power and load uncertainties. Moreover, a novel source‐load bilateral carbon trading (BCT) mechanism based on the Aumann–Shapley method is proposed to stimulate the WTG and DSB configuration. In the bi‐layer planning framework with BCT mechanism, WTG and DSB capacity planning with the two‐stage stochastic optimization are conducted in the upper and lower layer, respectively. Finally, test results on a modified IEEE 24‐bus system demonstrate that the proposed framework with BCT mechanism can effectively motivate the planning configuration of WTG and DSB and carbon mitigation. Compared with the models with unilateral carbon trading mechanisms, the proposed model has advantages in stimulating configuration of WTG and DSB, reducing carbon emissions, and balancing source‐load economic burden from carbon trading.

Effect of non-uniform stiffness distribution on the dynamics of inverted plates in a uniform flow
Authors: Zhang Chengyao , Zhao Zhiye , Huang Haibo , Lv Xingbing , Lu Xi-Yun , Yu Peng
Published: November 2022

The stability of the inverted flexible plate with non-uniform stiffness distribution in a free stream is studied by numerical simulation and mathematical theory. In our study, the bending stiffness distribution is expressed as the function of the leading edge's bending stiffness K∗ and the polynomial of the plate's coordinate. Based on the former theoretical work on the stability of inverted plates with uniform stiffness distribution, we derive the upper limit value of K∗ at which the zero-deflection equilibrium loses its stability for the plate with non-uniform stiffness distribution. The critical K∗ derived from the mathematical theory agrees well with that obtained from the numerical simulation. An effective bending stiffness is defined, which can be used to unify the regimes of the motion modes between uniform plates and non-uniform plates. Moreover, three orders of mass ratio [O(10−2), O(10−1), and O(1)] are investigated, and the underlying mechanism for large amplitude flapping is clarified for the inverted plate with different mass ratios. An appropriate bending stiffness distribution can greatly improve the deformation of the plate. The findings shed some light on the energy harvesting of the inverted plate.
Electrophoresis of a soft particle with a hydrophobic rigid core decorated with a soft-step and partially ion-penetrable polymer layer
Authors: Chowdhury Sourav , Mahapatra Paramita , Ohshima H. , Gopmandal Partha P.
Published: November 2022

On the basis of flat-plate formalism, we present an analytical theory for the electrophoresis of soft particles consisting of a hydrophobic inner core decorated with a layer of inhomogeneously distributed polymer segments. Biocolloids or bio-compatible drug delivery vehicles often carry the non-wettable or hydrophobic inner core. In addition, due to electrostatic swelling/shrinking processes, a spatially varying heterogeneity can be seen in the monomer distribution as well as charge properties of the peripheral polyelectrolyte layer (PEL). We adopt the soft-step function to model the chemical and structural anisotropy of the peripheral PEL. In addition, the PEL for the aforementioned bio-systems immersed in aquatic microenvironment often induces dielectric gradient-mediated ion partitioning effect, which in turn leads to the PEL to be partially ion penetrable. Within the Debye–Hückel electrostatic framework, we derive a general expression for electrophoretic mobility of a soft particle considering the combined impacts of hydrophobicity of the inner core, inhomogeneously distributed segment distribution accompanied by chemical heterogeneity and ion partitioning effect. We further derived asymptotic limits of the more generic results detailed here under several electrostatic and hydrodynamic conditions.
Numerical verification of sharp corner behavior for Giesekus and Phan-Thien–Tanner fluids
Authors: Evans J. D. , Palhares Junior I. L. , Oishi C. M. , Ruano Neto F.
Published: November 2022

We verify numerically the theoretical stress singularities for two viscoelastic models that occur at sharp corners. The models considered are the Giesekus and Phan-Thien–Tanner (PTT), both of which are shear thinning and are able to capture realistic polymer behaviors. The theoretical asymptotic behavior of these two models at sharp corners has previously been found to involve an integrable solvent and polymer elastic stress singularity, along with narrow elastic stress boundary layers at the walls of the corner. We demonstrate here the validity of these theoretical results through numerical simulation of the classical contraction flow and analyzing the 270° corner. Numerical results are presented, verifying both the solvent and polymer stress singularities, as well as the dominant terms in the constitutive equations supporting the elastic boundary layer structures. For comparison at Weissenberg order one, we consider both the Cartesian stress formulation and the alternative natural stress formulation of the viscoelastic constitutive equations. Numerically, it is shown that the natural stress formulation gives increased accuracy and convergence behavior at the stress singularity and, moreover, encounters no upper Weissenberg number limitation in the global flow simulation for sufficiently large solvent viscosity fraction. The numerical simulations with the Cartesian stress formulation cannot reach such high Weissenberg numbers and run into convergence failure associated with the so-called high Weissenberg number problem.
Segmentation of schlieren images of flow field in combustor of scramjet based on improved fully convolutional network
Authors: Li Linjing , Tian Ye , Deng Xue , Guo Mingming , Le Jialing , Zhang Hua
Published: November 2022

Extraction of the wave structure of the flow field in the combustor of the scramjet is important for main flow control and performance evaluation of the scramjet. In this study, a deep learning-based method based on the fully convolutional network with 8-pixel stride is proposed to segment the schlieren image to extract the wave structure. First, use a residual neural network with 34 layers as the backbone network to extract features, which ensures highly efficient learning through residual blocks to extract multi-dimension semantic information. Second, dilated convolution is utilized to expand the receptive fields of deepened layers to obtain high-dimensional features and increase the degree of aggregation of contextual information contained in the high-dimensional features. Finally, the channel and spatial attention module are introduced to the decoding stage to enable the model to focus on key information to improve the segmentation accuracy. A large number of experiments are carried out on a dataset of schlieren images of the flow field in the combustor of scramjet that were compiled by the authors. The proposed method recorded higher values of the pixel accuracy, recall, intersection over union, and F1 score than compared methods, with values of 78.47%, 83.81%, 67.51%, and 80.32%, respectively. This method can effectively complete the wave structure extraction and provide important basic support for related research work of scramjet.
Analytical model of hydraulic fracturing horizontal well gas production capacity of a water-bearing tight sandstone reservoir considering planar heterogeneity
Authors: Liu Yuwei , Zhu Weiyao , Kong Debin , pan Bin , Yue Ming
Published: November 2022

Previous models of the gas-production rate of hydraulic fracturing horizontal wells were by assuming permeability heterogeneity, which is unrealistic in water-bearing tight gas reservoirs because of sandstone–mudstone crossover. Therefore, we develop an analytical model to describe the gas-production dynamics of hydraulic fracturing horizontal wells that consider permeability heterogeneity. In addition, threshold pressure gradient, stress sensitivity, and slippage are incorporated into the model. To solve this model analytically, the elliptical flow is transformed to radial flow by conformal transformation. The gas-production rate, reservoir pressure distribution, and average formation pressure are obtained by superposition principle, boundary pressures are calculated by material balance method, and the dynamic supply boundary propagation is modeled by steady-state sequential replacement. Actual field production data from Ordos Basin, China, is used to verify the new model, which increases the accuracy by 11.3% over previous models (98.6% vs 87.3%). The propagation distance of the dynamic supply boundary is predicted (in the fracture direction, it is 109.3 m, and in the vertical fracture direction, it is 44.2 m). We analyze how stress sensitivity, the dynamic threshold pressure gradient, matrix permeability, pressure difference, and initial water saturation affect gas production rate and dynamic supply boundary. Based on orthogonal experimentation, the factors affecting the gas production rate and dynamic supply boundary of tight gas reservoirs can be ranked in the following order: pressure difference > permeability > initial water saturation. This analytical model can accurately characterize gas production and pressure response, and it is easy to use and rapid to calculate.
Investigation on the hump region generation mechanism of pump mode in low-head pumped hydro-storage unit
Authors: Zhao Haoru , Wang Fujun , Wang Chaoyue , Wang Benhong
Published: November 2022

The pump mode of the low-head pumped hydrostorage unit (pump-turbine) may operate in the hump region under extreme conditions due to the influence of water level variation, and the resulting energy conversion instability will seriously threaten the safety of the unit. However, the generation mechanism of the hump region is still not sufficiently understood, which is mainly due to two reasons: the dominant unstable flow structures that induce the formation of the hump region have not been uniformly recognized, and the influence of the dominant unstable flow structures on the impeller's working capacity has not been effectively revealed. In this study, experiments and numerical simulations were carried out on the low-head pumped hydrostorage unit in the pump mode, and the following results were obtained. It is found that the dominant unstable flow structures that induce the formation of the hump region are the leading edge backflow on the blade inlet shroud side and the horn-like vortex on the blade outlet hub side. The leading edge backflow reduces the blade loading and limits the impeller's working capacity, and the horn-like vortex increases the blade loading and increases the impeller's working capacity. The analysis revealed that the formation of the hump region is the result of the mutual restriction of the horn-like vortex and the leading edge backflow.

Conclusion The expertise of nurses must be sought to ensure artificial intelligence can effectively meet the highly context-specific demands of the healthcare environment.
It’s all about the sentential construction
Authors: Becker Israela
Published: November 2022

Cross-linguistically, very few complete sentences, as opposed to a myriad of phrases, lexicalize to become words.
I here offer an account for this skewed distribution, along the lines of Construction Grammar, by analyzing a set of mono-clausal
sentences in Hebrew which have indeed become – or are on the verge of becoming – words. I adopt the distinction between
categorical and thetic propositions, and show that only the latter can evolve into words. A thetic – unlike a categorical –
proposition, much like a verb-phrase, enables a tight semantic bonding between its components to form an ‘interpretatively
cohesive’ unit, which may lead to semantic change. An evaluative thetic – unlike a categorical – proposition is comment-like,
hence ‘semantically-incomplete’, and in need of a topic from prior discourse to predicate on, which may lead to a change in
grammatical status. All verb-phrases meet these two criteria but only few sentences do, hence, I argue, the skewed distribution of
sources from which new words evolve.
Predicted superconductivity and superionic state in the electride Li5N under high pressure
Authors: Wan Zhongyu , Zhang Chao , Yang Tianyi , Xu Wenjun , Zhang Ruiqin
Published: November 2022

Recently, electrides have received increasing attention due to their multifunctional properties as superconducting, catalytic, insulating, and electrode materials, with potential to offer other performance and possess novel physical states. This work uncovers that Li5N as an electride possess four novel physical states simultaneously: electride state, super-coordinated state, superconducting state, and superionic state. By obtaining high-pressure phase diagrams of the Li–N system at 150–350 GPa using a crystal structure search algorithm, we find that Li5N can remain stable as P6/mmm structure and has a 14-fold super-coordination number, as verified by Bader charge and electron localization function analysis. Its superconducting transition temperature reaches the highest at 150 GPa (T
c = 48.97 K). Besides, Li5N exhibits the superionic state at 3000 K, in which N atoms act like solid, while some Li atoms flow like liquid. The above results are further verified at a macroscopic level by using deep learning potential molecular dynamics simulations.

Authors: Nur M , Handayani W
Published: November 2022

Water-related disasters, such as floods and drought, continue to occur in the Comal Watershed area because of several reasons such as high growth of land conversion and insufficient policy support. Each type of disaster happens in a particular prone area that can be identified based on certain characteristics. Accordingly, this paper aims to identify the typology of the occurring disaster and subsequently assess the disaster risk reduction efforts that have been implemented by government institutions. Content analysis was applied to further explore the disaster phenomena in the area. Data obtained from various secondary data sources such as mass media and planning documents related to the selected basin. The results of the study show that catastrophic disasters take place in particular natural physical conditions of the river basin. Other than that, disaster risk reduction efforts have been conducted in accordance with the efforts of integrated water resources management.

Authors: Ervin M , Anafi M A , Arif A , Puspita H R A , Dewi A N , Ashari A
Published: November 2022

The study on the potential of springs is urgently needed to support sustainable development in the stratovolcano area. This study was conducted in the junction of Sumbing and Sindoro stratovolcano, to analyze the characteristics of springs which include the pattern of distribution, discharge, and, water quality. The data were collected by employing observation, literature study, and documentation. The data analysed using GIS, statistical and descriptive analysis. The results show that springs patterns are random. The spring discharge in both volcanoes varies between class V to VI. Between the Sumbing and Sindoro there is no difference in the average of discharge, water temperature, DO, and pH, but it is different in the average of TDS and EC. Water temperature has a strong influence on EC in Sumbing but weak in Sindoro. The increase in water temperature has a weak effect on the decrease of DO in both volcanoes. The decrease in spring elevation influences the increase in water temperature, strong in Sumbing but weak in Sindoro. The difference in geomorphological conditions between Sumbing and Sindoro contributes to the variation of the spring’s characteristics. Overall, this paper presents new insights to understand the effect of different geomorphological conditions in two adjacent stratovolcanoes on the characteristics of springs.
Young Citizens’ Perceptions of Informal Green Space - A Study of Japanese High School Student's Place Attachment and Desire to Live in Rural Areas
Authors: Tanaka Yuri , Mao Yingming , Furuya Katsunori
Published: November 2022

One of the Sustainable Development Goals (SDGs) adopted at the UN Summit in September 2015 includes the greening movement, in which ordinary citizens can actively participate. Goals 3, 11, 13, and 15 of SDGs contribute to health and well-being, sustainable cities and communities, measures against climate change, and protection of life on land, respectively. In this context, studies of urban green spaces have been conducted on greening movements. Most studies have focused on formally recognized green spaces such as parks, gardens, and forests. “Informal green spaces” refer to small plots of land covered with greenery such as grassy areas on roadsides, vacant lots, and vegetation beside railroad tracks and waterways; however, they are considered separate from formal green spaces. A previous survey of informal green space usage in Ichikawa City, Chiba Prefecture, showed that residents were aware of informal green spaces in their neighborhoods and viewed them as potential auxiliary green spaces. However, the study mainly focused on the elderly, and no studies have focused on youth from junior high or high school as the primary research target. Therefore, this study aimed to clarify whether the results from previous studies were relevant to younger generations and a broader range of cities.

This study focuses on the cities near Ichikawa, located in the metropolitan area of Japan, urbanized with residential condominiums and other buildings. There are several formal green spaces, and interest in greenery is relatively high. We first surveyed the actual conditions of various informal green spaces in Chiba and recorded their location information and types. Based on the data obtained, a questionnaire on the use and evaluation of informal green spaces was designed, and the responses were collected using “Classi,” an ICT platform for students and teachers, from Ichikawa Gakuen’s students (junior high school to senior high school) and teachers.

Green spaces can help to build a sustainable society by improving physical and mental health through exposure to nature, developing cities where people can continue to live, and reducing heat islands. The importance of formal and informal green spaces in cities has been highlighted in this study, which indicated that informal green spaces not only enrich people’s lives but also have the potential for new usage. This study emphasizes that in urban areas with many restrictions, informal green spaces play a complementary role to formal green spaces.
Permaculture Landscape as an Adaptive Strategy towards Food Security at Community-Scale
Authors: Kurniawati I , Dahlan M Z , Faisal B
Published: November 2022

Food security still becomes a big challenge nowadays, especially since the spreading of Covid-19 pandemic. Facts show that a large-scale social restriction policy in Indonesia limits the movement of logistics to distribute food. This situation tends to worsen due to the limited number of agricultural lands. Environmental or ecological sustainability in agriculture activity is also rarely considered, making the land poor for agriculture. Permaculture can be a viable approach to achieve sustainable food security, by creating a cultivated ecosystem which provides necessary human needs along with natural regeneration. Kuttab Al Fatih (KAF) Islamic School was chosen as the case study because contextually KAF has the potential to implement permaculture to its landscape development. Therefore, this paper discusses how to implement permaculture to KAF landscape development. This research was conducted with a literature review, field survey, and case study to determine permaculture design considerations within the selected project. The findings show that the permaculture landscape encourages the people to serve their needs (including foods) within the site without harming the environment. Through mimicking nature and adapting the pattern, permaculture system can create a sustainable ecosystem for people and other creatures to live in harmony. The implementation of permaculture at KAF should consider the Islamic values and the prohibitions in order the implementation does not conflict with user’s beliefs. User’s food needs, procurement, and human resources become another factor that should be considered to ensure the permaculture implementation is visible at KAF since the users are not staying at school.

Published: November 2022

Gajah Park as a green open space and public space in Bandar Lampung has a socio-cultural function such as a communication medium and a recreation place for residents. To support this function, the existing condition of the Gajah Park has several available facilities such as; commercial area, talent training area, children’s playground and others. However, these facilities lack clear territorial boundaries so that the visitors who come to Gajah Park can move from one area to another freely. This condition also causes crowding in some areas and hard to maintain physical distancing, especially in the current Covid-19 pandemic situation. This research aims to evaluate the existing condition of the Gajah Park and to figure out the benefits of border elements as landscape elements to influence behaviour and limit the movement of visitors to maintain physical distancing. This research uses a descriptive qualitative method by collecting data fields and observations to determine the dimension of the site, behaviour setting, behaviour mapping, and the existing condition of border elements. The result of this study is the recommendation of border element’s design to apply in Gajah Park.

Published: November 2022

A damping fuzzy proportional-integral-derivative (PID) control method for electronically controlled air suspension shock absorbers was proposed to reduce the RMS values of the body vibration acceleration and improve vehicle ride comfort. Depending on the operating mode of the electronically controlled air suspension shock absorber, a mechanical model of the air suspension shock absorber was established. A fuzzy PID control technology for damping control of the shock absorber is designed by combining a PID control algorithm with the fuzzy control concept. The adaptive expansion factor of the cybernetics domain for the fuzzy PID controller is calculated by considering nonlinear characteristics and time delay to improve the controller’s adaptability. Then, the control parameters are adjusted based on the control deviation and deviation rate parameters. The nonlinear detection platform produced by an enterprise is selected to build an experimental environment for analysis. Simulation results reveal that when the vehicle speed is 30 km h−1, the RMS values of the body vibration acceleration upon applying the proposed method is approximately 0.02 and 0.05 km h−2, respectively, on Class B and C road surfaces. Furthermore, the RMS values of the body vibration acceleration using the proposed method has little fluctuation; when the vehicle speed is 60 km h−1, the RMS values of the body vibration acceleration is 0.022 and 0.028 km h−2, respectively, on Class B and C road surfaces, indicating that the proposed method can effectively reduce the RMS values of the body vibration acceleration and improve rider comfort.
How are Atlantic basin-wide hurricane activity and economic losses related?
Authors: Hemmati Mona , Camargo Suzana J , Sobel Adam H
Published: November 2022

The authors investigate the statistical relationships between interannual variations in economic losses from Tropical Cyclones (TCs), basin-wide metrics of TC activity, and indicators of large-scale climate variability in the North Atlantic basin. The results show substantial and statistically significant correlations between the economic losses and some seasonal TC activity metrics, namely the accumulated cyclone energy and power dissipation index. These results suggest that accurate seasonal forecasts of these metrics can be taken as relevant to potential TC losses, even though the metrics in question do not take into account whether storms make landfall, let alone where they do so. The authors suggest that the degree of correlation obtained might be considered a baseline against which to measure some aspects of the performance of catastrophe models.

Published: November 2022

Background

Leucine-rich alpha-2 glycoprotein (LRG) is a novel serum biomarker for inflammation in inflammatory bowel disease (IBD). This prospective study aimed to compare the value of LRG with C-reactive protein (CRP) and fecal calprotectin for evaluating clinical and endoscopic disease activity in patients with IBD.

Methods

At entry, clinical and endoscopic disease activity was assessed in 267 patients with IBD (ulcerative colitis [UC] 203; Crohn’s disease [CD] 64), and the levels of LRG, CRP and fecal calprotectin were measured. The accuracy of the biomarkers for the detection of clinical and endoscopic disease activity was determined by the area under the receiver operating characteristic curve.

Results

Leucine-rich alpha-2 glycoprotein showed a significant relationship with the clinical and endoscopic severity in both UC and CD (both diseases, P < .0001). In the clinical assessment of UC, the accuracy of LRG was significantly higher than that of CRP (0.73 vs 0.63; P < .001). In the endoscopic assessment of UC, the accuracy of LRG was significantly higher than that of CRP (P = .01), but it was significantly lower than that of fecal calprotectin (P = .009; LRG, 0.80; CRP, 0.72; fecal calprotectin, 0.91). In the clinical and endoscopic assessment of CD, the accuracy was not significantly different between the biomarkers (clinical activity: LRG, 0.71; CRP, 0.64; fecal calprotectin, 0.66; in endoscopic activity: LRG, 0.79; CRP, 0.78; fecal calprotectin, 0.81).

Conclusions

Leucine-rich alpha-2 glycoprotein is a reliable serum biomarker for the assessment of clinical and endoscopic disease activity in patients with IBD. It can be an alternative to CRP for the assessment of UC.

Published: November 2022

Background

There are reports for the simultaneous estimation of sildenafil (SIL) and tramadol (TM) using chromatographic techniques. Some limitations of these methods are high cost and time, more usage of pollutant solvents, and complicated instruments.

Objective

Simultaneous determination of SIL and TM in the anti–sexual dysfunction pharmaceutical formulation using rapid and smart chemometrics approaches along with spectrophotometry.

Method

In this study, a spectrophotometric analysis method based on continuous wavelet transform (CWT), partial least-squares (PLS), and radial basis function neural network (RBF-NN) was presented.

Results

In the CWT method, the Symlet (Sym2) and Daubechies (db2) wavelet families with wavelengths of 268 and 221 nm were considered the best families for SIL and TM, respectively. The limit of detection (LOD) and limit of quantitation (LOQ) values were found to be 0.0185, 0.0054 μg/mL and 0.0458, 0.3092 μg/mL for SIL and TM, respectively. The mean recovery values were 101.06 and 101.49% for SIL and TM, respectively. The results of PLS revealed that the root-mean-square error (RMSE) of SIL and TM was 0.0286 and 0.0635, respectively. Also, the mean recovery of both drugs was obtained over 99%. The mean square error (MSE) of RBF-NN was 5.88 × 10−29 and 4.61 × 10−27 for SIL and TM, respectively.

Conclusions

A statistical comparative study conducted for the proposed methods with the high-performance liquid chromatography (HPLC) technique demonstrated no significant difference between these methods. The suggested approaches were simple, fast, accurate, and affordable.

Highlights

Three smart UV spectrophotometric methods based on chemometrics were presented to determine SIL and TM simultaneously. The efficient chemometrics methods, including CWT, PLS, and RBF-NN, were used. The mentioned methods are rapid, simple, inexpensive, and accurate. The comparison was performed between the proposed models and HPLC technique.
