Published: February 2023

The phytochemical investigation of the roots of the traditional Chinese medicinal plant Sophora flavescens led to the isolation of two novel prenylflavonoids with an unusual cyclohexyl substituent instead of the common aromatic ring B, named 4′,4′-dimethoxy-sophvein (17) and sophvein-4′-one (18), and 34 known compounds (1–16, 19–36). The structures of these chemical compounds were determined by spectroscopic techniques, including 1D-, 2D-NMR, and HRESIMS data. Furthermore, evaluations of nitric oxide (NO) production inhibitory activity against lipopolysaccharide (LPS)-treated RAW264.7 cells indicated that some compounds exhibited obvious inhibition effects, with IC50 ranged from 4.6 ± 1.1 to 14.4 ± 0.4 μM. Moreover, additional research demonstrated that some compounds inhibited the growth of HepG2 cells, with an IC50 ranging from 0.46 ± 0.1 to 48.6 ± 0.8 μM. These results suggest that flavonoid derivatives from the roots of S. flavescens can be used as a latent source of antiproliferative or anti-inflammatory agents.

The choroidal vascularity index (CVI) is a new biomarker defined for retinal optical coherence tomography (OCT) images for measuring and evaluating the choroidal vascular structure. The CVI is the ratio of the choroidal luminal area (LA) to the total choroidal area (TCA). The automatic calculation of this index is important for ophthalmologists but has not yet been explored. In this study, we proposed a fully automated method based on deep learning for calculating the CVI in three main steps: 1—segmentation of the choroidal boundary, 2—detection of the choroidal luminal vessels, and 3—computation of the CVI. The proposed method was evaluated in complex situations such as the presence of diabetic retinopathy and pachychoroid spectrum. In pachychoroid spectrum, the choroid is thickened, and the boundary between the choroid and sclera (sclerochoroidal junction) is blurred, which makes the segmentation more challenging. The proposed method was designed based on the U-Net model, and a new loss function was proposed to overcome the segmentation problems. The vascular LA was then calculated using Niblack’s local thresholding method, and the CVI value was finally computed. The experimental results for the segmentation stage with the best-performing model and the proposed loss function used showed Dice coefficients of 0.941 and 0.936 in diabetic retinopathy and pachychoroid spectrum patients, respectively. The unsigned boundary localization errors in the presence of diabetic retinopathy were 3 and 20.7 μm for the BM boundary and sclerochoroidal junction, respectively. Similarly, the unsigned errors in the presence of pachychoroid spectrum were 21.6 and 76.2 μm for the BM and sclerochoroidal junction, respectively. The performance of the proposed method to calculate the CVI was evaluated; the Bland–Altman plot indicated an acceptable agreement between the values allocated by experts and the proposed method in the presence of diabetic retinopathy and pachychoroid spectrum.

Published: February 2023

We have designed and fabricated a kind of supersymmetric slotted Fabry–Perot semiconductor laser near 1550 nm to achieve a single-mode, high-power, and narrow-linewidth operation. The structure of the laser is composed of an electrically pumped broad ridge waveguide in the middle to provide optical gain, a group of periodic slots etched near the front facet to suppress the extra longitudinal modes and achieve a narrow linewidth, and a pair of passive superpartner waveguides located on both sides to filter out the high-order lateral modes in the broad waveguide. The device measured under the temperature of 25 °C shows an output power of 113 mW, a single-lobe lateral far-field distribution with the full width at half maximum of 7.8°, a peak wavelength of 1559.7 nm with the side-mode suppression ratio of 48.5 dB, and an intrinsic linewidth of 230 kHz at the bias current of 800 mA. The device is a promising candidate for cost-effective light sources for coherent communication systems and LiDARs.
Vehicle Routing Problem Model with Practicality

Published: February 2023

Truck platooning has recently become an essential issue in automatic driving. Though truck platooning can increase safety and reduce fuel consumption and carbon emissions, the practical vehicle routing problem involved in truck platooning has not been sufficiently addressed. Therefore, we design a mixed-integer linear programming model for the routing problem in truck platooning considering the deadline of vehicles, continuous-time units, different fuel reduction rates, traffic congestion avoidance, and heterogeneous vehicles. In addition, a forward–backward heuristic called the “greedy heuristic” is presented for reasonable computation time. To validate the model’s performance, several parameters, such as the percentage of fuel reduction, percentage of detour vehicles, and percentage of platooned links (road segments), are considered. Additionally, various cases are considered with varying fuel reduction rates, traffic flow rates, and time windows.
Automatic Identification of Children with ADHD from EEG Brain Waves

Published: February 2023

EEG (electroencephalogram) signals could be used reliably to extract critical information regarding ADHD (attention deficit hyperactivity disorder), a childhood neurodevelopmental disorder. The early detection of ADHD is important to lessen the development of this disorder and reduce its long-term impact. This study aimed to develop a computer algorithm to identify children with ADHD automatically from the characteristic brain waves. An EEG machine learning pipeline is presented here, including signal preprocessing and data preparation steps, with thorough explanations and rationale. A large public dataset of 120 children was selected, containing large variability and minimal measurement bias in data collection and reproducible child-friendly visual attentional tasks. Unlike other studies, EEG linear features were extracted to train a Gaussian SVM-based model from only the first four sub-bands of EEG. This eliminates signals more than 30 Hz, thus reducing the computational load for model training while keeping mean accuracy of ~94%. We also performed rigorous validation (obtained 93.2% and 94.2% accuracy, respectively, for holdout and 10-fold cross-validation) to ensure that the developed model is minimally impacted by bias and overfitting that commonly appear in the ML pipeline. These performance metrics indicate the ability to automatically identify children with ADHD from a local clinical setting and provide a baseline for further clinical evaluation and timely therapeutic attempts.

Published: February 2023

The South Slope District of the Mahu Depression in the Junggar Basin, a major favorable zone for middle and superficial oil–gas exploration, has experienced industrial gas flow. However, research on the sedimentary microfacies characteristics of Segment 2 of the Sangonghe Formation, the main oil-bearing formation, remains lacking. In this study, the rock type, sedimentary tectonics, and sedimentary microfacies of Segment 2 of the Jurassic Sangonghe Formation in the South Slope District of the Mahu Depression were thoroughly investigated through 3D seismic, rock core, and logging data. Moreover, the sedimentary modes and distribution characteristics of the sand bodies in the study area were further analyzed. Results showed that subfacies at the front edge of the braided river delta are developed at Segment 2 of the Sangonghe Formation, which can be further divided into four microfacies types, namely, underwater distributary channel, sheet sand, estuary dam, and interdistributary bay. The estuary dam is only developed at local positions in the work area. The vertical evolutionary laws from Segment 2 of the Sangonghe Formation to Segment 3 of the Sangonghe Formation are explicit and manifest as retrogradation from the subfacies at the front edge of the braided river delta to the prodelta. The sand bodies formed by frequent swings of the underwater distributary channels are the main reservoir bodies, and the lithology is mainly fine-grained feldspar lithic sandstone, and sedimentary tectonics have diverse forms. On the basis of deposition microphase analysis, the sand bodies’ planar distribution characteristics under phase-controlled conditions were analyzed using a seismic model inversion technology to provide theoretical guidance for oilfield expansion, exploration, and exploitation.

Published: February 2023

Conductive polymer polypyrrole (PPy)-coated lithium-rich manganese-based Li1.2Mn0.54Ni0.13Co0.13O2 (LMNCO) nanotube cathode materials were synthesized by electrospinning and subsequently subjected to low-temperature vapor-phase polymerization. X-ray diffraction (XRD), scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM) results confirm that the successful coating of the PPy layer (~2 nm) on the surface of LMNCO nanotubes did not destroy their morphologies or structures. Electrochemical tests indicate that the electrochemical performance of PPy-coated LMNCO nanotubes has been significantly enhanced. At a rate of 1 C, the discharge capacity of the PPy-coated LMNCO cell is 200.1 mAh g−1, and the capacity retention is 99% after 120 cycles. This excellent stability is attributed to the inhibition of side reactions and the protective function of the tubular structure due to the PPy coating layer. Additionally, the rate capability is also improved at a high current density due to the higher electronic and ionic conductivity.

Published: February 2023

This study aimed to assess the semen quality after the cooling and freezing of the first and second ejaculates of the season, which were collected 1 h apart. After collection (n = 40 ejaculates), the gel-free semen volume, concentration, total number of sperm, and sperm morphology were determined. An aliquot of each ejaculate was extended and cooled for 48 h; a second aliquot was cushion-centrifuged and cooled for 48 h; and a third aliquot was processed and then frozen. The total motility (TM) and progressive motility (PM), plasma membrane integrity (PMI), and high mitochondrial membrane potential (HMMP) were assessed pre-(0 h), 24 h, and 48 h post-cooling and before and after freezing. The second ejaculate had a lower gel-free semen volume (p = 0.026). The sperm concentration was greater in the first than in the second ejaculate (p < 0.001). The sperm morphology was similar between the ejaculates (p > 0.05). Cushion-centrifugation prevented a reduction in the TM, PM, and PMI over time (p < 0.05). The TM, PM, and PMI decreased after freezing but not between the ejaculates (p > 0.05). The first and second ejaculates of the season, which were collected 1 h apart, varied in quantity but not in quality after cooling and freezing.
Progressive Right Ventricular Obstruction Caused by a Double-Chambered Right Ventricle Resulting in Shunt-Reversal via a Concomitant Congenital Ventricular Septal Defect and Subsequent Erythrocytosis in a Dog

Published: February 2023

A 3-year-old Chihuahua was presented because of exercise intolerance, respiratory distress, and syncopal episodes. At the age of 10 weeks, the dog was diagnosed with a congenital small left-to-right shunting ventricular septal defect and a mild right ventricular outflow tract obstruction via echocardiography. At that time, the dog was asymptomatic, but the breeder’s veterinarian heard a murmur. Both cardiac defects were judged to be clinically non-relevant at that time. However, at 3 years of age, echocardiography revealed a severe right ventricular obstruction, known as a double-chambered right ventricle, along with right-to-left shunting via the ventricular septal defect. Because of chronic hypoxemia due to the right-to-left shunting, erythrocytosis developed. Flow reversal via the shunt was caused by a progressively worsening right ventricular obstruction leading to a supra-systemic right ventricular systolic pressure. Because of the poor prognosis, the dog was euthanized, and the heart was submitted for post-mortem examination. Gross pathologic findings revealed the close proximity of the right ventricular obstructive lesion to the ventricular septal defect. Histopathology revealed localized muscular hypertrophy and severe endocardial fibrosis. The suspected pathogenesis of the progressive obstruction was infiltrative myocardial fibrosis due to turbulent blood flow from the left-to-right shunting ventricular septal defect, as described in humans.
From Gung Ho Heroes and Their Tragic Counterparts to Catalyst Characters
Authors: Strandvad Sara Malou
Published: February 2023

The term cultural entrepreneurship is increasingly used in academic research to address the intersection of business developments and creative work. However, the concept itself is disputed. Unpacking varying definitions of the term, this article revisits literature on the topic, searching for the figures of the cultural entrepreneur that scholars create. The article suggests that the literature is dominated by hero figures, who are based on retrospective analyses of successful individuals, and tragic hero figures, who summarize the situation for most self-employed creatives, establishing a bleak outlook. As an alternative, the article suggests seeing cultural entrepreneurs as catalyst figures.

Le site de la République est localisé en bordure de microfalaise à Talmont-Saint-Hilaire en Vendée (France). Il s’intègre au sein d’un vaste réseau d’occupations campaniformes observable tout le long du littoral vendéen, où près d’une quinzaine de sites sont attestés. Il a été découvert en 1968 par R. Joussaume suite à des prospections de surface et a fait l’objet de plusieurs opérations archéologiques de sauvetage entre 1988 et 2015 (B. Poissonnier en 1988, J.-M. Gilbert en 1990, H. Gandois et L. Rousseau en 2014 et 2015). En effet, il fait face à une érosion marine constante faisant apparaître très régulièrement des vestiges en surface ou en coupe de falaise. Cet article permet de faire le point sur cinquante années de découvertes effectuées sur cette vaste occupation attribuée à la culture campaniforme. Cette dernière se caractérise par un important lot de céramiques (l’un des plus conséquents pour le nord-ouest de la France : vases décorés à la coquille et au peigne et vases à cordons) et de pièces lithiques (débitage par percussion posée sur enclume, outils macrolithiques liés à des activités domestiques et de taille et amas de débitage), mais aussi par des indices d’une métallurgie cuprifère précoce. Cette dernière a été reconnue dès les interventions anciennes par la présence de scories et de deux structures possiblement associées (même si l’hypothèse de structures à sel peut être aussi suggérée). Les dernières fouilles ont permis de montrer que cette activité a été menée in situ par le biais d’une technique

inédite pour la façade atlantique, à savoir la réduction du minerai dans un vase-four. Enfin, les fouilles récentes ont été l’occasion d’apporter un nouveau regard sur ce site majeur, d’étudier l’intégralité du mobilier archéologique dont une grande partie était restée jusqu’alors inédite, ainsi que de réaliser de nouvelles analyses scientifiques (tracéologie, datation 14C, analyses des éléments cuivreux et des résidus de cuisson dans les céramiques).

Published: February 2023

The ant (Pheidole megacephala, Fabricius) has a unique and hard mandibular structure to cut branches and crush hard food. Inspired by this special geometric structure of the mandibular teeth, a stereoscopic microscope was used to view the image of the mandible of the ant. The Origin and AutoCAD software were used to obtain the outer profile of the mandibular teeth of the ant. The outer profile of the ant's mandibular teeth was fitted and expressed by five-order polynomial function. According to the analysis of the profile curve of the maxillary teeth, the fourth tooth is the most convex and the sharpest. The fourth tooth of the ant plays a key role in its feeding process, therefore, the structural parameters of the fourth maxillary tooth were selected as bionic elements for bionic blade design. To compare the cutting performance of the bionic and ordinary flat blades, the performance of bionic blade and the ordinary blade were conducted by using ANSYS software, the cutting force-deformation characteristics were tested using the Rapid TA practical texture analyser. The results of the element simulation showed that the mechanical properties of bionic blade were better than those of the ordinary blade. The results of the cutting experiments indicated that under the loading speed of 5 mm/s, the maximum cutting force of the bionic blade was 137.51 N, which is 12.17 % lower than that of the ordinary flat blade. The average cutting force of the bionic blade was 96.56 N, which is 11.58 % lower than that of the ordinary flat blade. The cutting energy consumption of the bionic blade was 9.68 J, which is 11.92 % lower than that of the ordinary flat blade. Under the loading speed of 10 mm/s, the maximum cutting force of the bionic blade was 143.88 N, which is 10.37 % lower than that of the ordinary flat blade. The average cutting force of the bionic blade was 101.03 N, which is 9.77 % lower than that of the ordinary flat blade. The cutting energy consumption of the bionic blade was 10.14 J, which is 9.95 % lower than that of the ordinary flat blade. The experimental results suggested that the bionic blade can effectively reduce the cutting force and energy consumption; thus, the bionic blade is more suitable for cutting stalks. These results will be helpful in the development of cutting elements for cutting and chopping of corn stover and other processing machinery.
RESEARCH ON THE ACCUMULATION AND TRANSFER OF HEAVY METALS FROM THE SOIL TO BERRIES (BLUEBERRIES - VACCINIUM MYRTILLUS L. AND RASPBERRIES - RUBUS IDAEUS)
Authors: NIȚU Mihaela , PRUTEANU Augustina , GĂGEANU Iuliana
Published: February 2023

The current study has investigated the accumulation and transfer coefficient for three heavy metals (Cu, Pb, Zn) found in the contaminated soil with three concentrations (c1=1.5%, c2=3.0%, c3=4.5%, c4=6.0%), obtained by mixing the three metals, in blueberry and raspberry fruits. The pots in which the shrubs were planted were loaded with fertile soil which was mixed and homogenized in turn with each of the three solutions of different concentrations. The highest accumulation in blueberry fruits was recorded for zinc, then copper and the lowest for lead, while for raspberries the highest results was recorded for zinc, then lead and the lowest for copper. The findings are valid for all four concentrations used. The transfer coefficient decreases as the concentration of heavy metals increases, thus for high heavy metal concentrations, the values of the transfer coefficient are very low, and for small heavy metal concentrations in the soil, the values for the transfer coefficient are higher. From the assessment of accumulation and transfer of heavy metals to berries (blueberries and raspberry) grown in the contaminated soil, it was concluded that all concentrations of the copper, lead and zinc mix have shown a low risk for human consumption.

Authors: Karasawa Shusaku , Saida Takahiro , Sharma Kamal Prasad , Naritsuka Shigeya , Maruyama Takahiro
Published: February 2023

In situ X-ray absorption fine structure (XAFS) analysis was performed on Ni catalysts during the growth of single-walled carbon nanotubes (SWCNTs) by alcohol catalytic chemical vapor deposition (ACCVD). Ni catalysts were gradually reduced during the heating process and became metallic at the growth temperature (800 °C). With the addition of ethanol during SWCNT growth, Ni catalysts were slightly carbonized. Such behavior was similar to that observed for Ir catalysts in our previous study, although the Ni catalysts had a carbon composition of ∼5%. The results of this study demonstrated the growth of SWCNTs from almost metallic catalysts under the conventional growth conditions of ACCVD using Ni catalysts. Our result obtained by in situ XAFS analysis was consistent with the result of atomistic computer simulations.

Oil and gas companies in order to maintain their efficiency in the conditions of: liberalization of markets, globalization, increased competition, reduction of consumer loyalty, constant variation in oil and gas prices, further development of Industry 4.0 and the Big Data factor, growing costs for drilling and completion – must have a flexible environment of information technologies that enables seamless and efficient sharing of knowledge throughout the company and along the entire value chain. One of the elements of this task is the effective use of hybrid knowledge-oriented decision support systems (DSS). This, in particular, determines the future stage of complex author's research – the development of a complex perforating knowledge management policy of an oil and gas company, the key tool for the implementation of which will be the hybrid, knowledge-oriented DSS considered in this publication.The form of knowledge representation has a significant impact on the characteristics and properties of a knowledge-oriented system. Therefore, based on the specifics of the exploration and development of oil and gas fields and the main advantages of the rule-oriented model of the DSS knowledge base, it is possible to conclude that it is necessary to use the KB rule-oriented basis for the DSS of an oil and gas production company. The rule-oriented subsystem is the main one in the knowledge-oriented DSS of an oil and gas production company, in fact, other subsystems provide it with analyses, assessments, and knowledge. Namely, the final product of the system: recommendations for making management decisions is carried out by a rule-oriented subsystem. In general, scientifically based conclusions were obtained regarding the knowledge-oriented architecture of the intellectual DSS of an oil and gas company, the basic model of knowledge presentation (production), the features of the mechanism of logical conclusion (direct logical conclusion), the conflict resolution procedure (a method of ordering products), etc. In the oil and gas industry, DSS built according to a hybrid approach have the greatest application potential – which are a powerful tool for solving complex specific problems of an oil and gas company. Therefore, in this work, the principles of hybrid application of intelligent technologies and the knowledge-oriented basis of DSS of an oil and gas company were further developed.

Authors: Ata Yalçın , Alouini Mohamed-Slim
Published: February 2023

This study evaluates the effect of application of spatial diversity technique, namely multiple-input multiple-output (MIMO), on the outage performance of free-space optical (FSO) communication systems operating in atmospheric turbulent medium for both slant path (downlink and uplink) and horizontal links. FSO communication links cover ground-to-high altitude platform system (HAPS), HAPS-to-ground, and HAPS-to-HAPS configurations. System model includes the combined effect of attenuation (resulting from absorption and scattering), angle-of-arrival (AOA) fluctuations, atmospheric turbulence, and pointing error. Atmospheric turbulent channel is characterized by Gamma-Gamma distribution. The Hoyt and Rayleigh distributions are used to model pointing error and AOA fluctuations, respectively. The performance of MIMO FSO communication links is presented depending on the various environmental and system parameters. Results show that the MIMO application in both transmitter and/or receiver can be a prominent alternative concerning the performance improvement for FSO communication links.
Optical embodiments of Rabi splitting based in photonic integrated waveguide-coupled resonators
Authors: Moss David
Published: February 2023

Realizing optical analogues of quantum phenomena in atomic, molecular, or condensed matter physics has underpinned a range of photonic technologies. Rabi splitting is a quantum phenomenon induced by a strong interaction between two quantum states, and its optical analogues are of fundamental importance for the manipulation of light-matter interactions with wide applications in optoelectronics and nonlinear optics. Here, we propose and theoretically investigate purely optical analogues of Rabi splitting in integrated waveguide-coupled resonators formed by two Sagnac interferometers. By tailoring the coherent mode interference, the spectral response of the devices is engineered to achieve optical analogues of Rabi splitting with anti-crossing behavior in the resonances. Transitions between the Lorentzian, Fano, and Rabi splitting spectral lineshapes are achieved by simply changing the phase shift along the waveguide connecting the two Sagnac interferometers, revealing interesting physical insights about the evolution of different optical analogues of quantum phenomena. The impact of the device structural parameters is also analyzed to facilitate device design and optimization. These results suggest a new way for realizing optical analogues of Rabi splitting based on integrated waveguide-coupled resonators, paving the way for many potential applications that manipulate light-matter interactions in the strong coupling regime. 
Edge Computing in the Internet of Things: A Survey
Authors: Elmassik Ziad
Published: February 2023

Over the past few decades, the conventional means for data computation were the exploitation of centralized cloud computers. However, with the proliferation of mobile devices and latency-sensitive applications, the conventional approach has grown inadequate. Instead, the edge computing paradigm is created to remedy the shortcomings of the cloud-based systems by transitioning computation of data from centralized data centers to the devices at the edge of the network. This presents a utopia of benefits such as low latency responses, efficient power consumption and ease of mobility for computing services. However, the implementation of edge computing is non-trivial and brings forth various challenges that must be addressed in order for edge computing to be fully developed. The goal of this paper is to better understand these challenges in hopes of neutralizing them.

Implementation of integrated project in chemical engineering courses has shown positive impact on students’ understanding, teamwork, critical thinking, and communication. In this case, an integrated project covering three different courses in chemical engineering, namely Reaction engineering, Process modelling and simulation, and Separation process was formulated on palm-oil based biodiesel production and introduced to students. The response from questionnaire was recorded and analyzed by using Excel software. More than 90% of students agree that the project helps them to understand the course and prepare for test or exam. While more than 70% of students want to see this type of project for other courses. Majority of students think that collaboration and teamwork help them to finish the project and doing integrated project saves their time to do assessment. Beside improving their soft skill like critical thinking, students can also sharpen their technical skills in solving the problems, especially on process flow drawing, operation of simulation tool, calculation technique, and search for suitable information and data. Through this integrated project, students could explore the connection among courses in Chemical Engineering program and implement the taught concepts in solving engineering problem, which can be challenging things to achieve during online learning.
Data Protection in Healthcare-Integrated Biobanking
Authors: Duhm-Harbeck Petra , Habermann Jens K.
Published: February 2023

Introduction

Development of personalized medicine depends on research using clinical biospecimens and data. This interface between clinical care and translational research is increasingly served by hospital-integrated biobanks; yet their implementation is hampered by complex data regulations.

Methods

A generic data protection concept with a decision and application matrix was developed addressing five criteria: (1) organizational integration into university medicine, (2) biobank governance, (3) ethical and legal aspects, (4) specifications of the BSI (Bundesamt für Sicherheit in der Informationstechnik [Federal Office for Information Security]), and (5) FAIR (findable, accessible, interoperable, and reusable) principles for research data. Applicability was tested for the highest complexity level at Campus Lübeck.

Results

The data protection concept was approved by the local ethics committee as well as local and national data protection authorities. The concept allows an automated research-guided patient recruitment and data protection-compliant information technology (IT) in connection to national and international research networks. It ensures university and hospital conformity with the EU Data Protection Regulation. Consent behavior of 277,766 patients over five years proved routine practicability (error rate 0.0013%; withdrawals 0.09%). Clinical staff obtained higher consent rates (85.6%) compared with consent rates for use of data only at central patient admission (56.1%); even though consents in central patient admission increased constantly during observation time.

Conclusion

The generic data protection concept can legitimately enable personalized medicine through biobanking in the clinical context.

Determinación del tipo de cambio real de equilibrio para el caso de México: un enfoque de cointegración
Authors: Jiménez Gómez Adrián
Published: February 2023

El objetivo de este artículo es estimar un tipo de cambio real de equilibrio en función del PIB y de la suma de los consumos privado y de gobierno, y de las exportaciones de México, del índice de producción industrial y de la inversión privada fija de EE.UU. Esta estimación se basa en el enfoque teórico de la oferta y demanda relativas; las cuales funcionan como determinantes del tipo de cambio real de equilibrio. Se obtienen un vector de cointegración y un modelo de corrección del error con datos trimestrales para el periodo 1995-2021, donde los signos de los coeficientes estimados en el espacio de cointegración corresponden al enfoque teórico. La comparación entre los tipos de cambio real observado y de equilibrio permite estimar un desalineamiento del peso mexicano, aún en un régimen de tipo de cambio flexible.
