Pasive and active intruders motion in a two-dimensional granular medium
Authors: Vidales-Hernández Citlalli Gabriela , Carrillo-Estrada Jose Luis , Donado Fernando
Published: June 2023

We study passive and active intruders moving through a two-dimensional granular medium. We use the radial distribution function and the sixth-bond-orientational order parameter to characterize the medium structurally and the mean squared displacement to characterize both the intruder and the medium dynamics. We start analyzing the movement of a passive intruder inside a granular media composed of soft spherical particles over a slightly tilted container under vibration and shear. We found that the intruder's trajectories fall through regions of less order of the granular medium. As expected, the passive intruder's motion increases the medium's disorder beside its path. For the task of comparison, we conducted experiments with an active intruder moving in a bead of particles distributed in a horizontal container. We observed again that the intruder moves through the more disordered regions, and as a consequence of its motion, the regions near its track get more ordered as the intruder passes. The intruder motion tends to be in closed paths; this effect is more noticeable for high particle concentrations. Finally, we study the motion of an active intruder in conditions similar to the passive intruder conditions. We observe that the active intruder, under these conditions, also moves through lower-order regions.

Objective
Deep-learning approaches have attracted attention for improving the scoring accuracy in computed tomography-less single photon emission computerized tomography (SPECT). This study evaluated the improvement in visual ischemia scoring accuracy to investigate the performance of virtual positron emission tomography (vPET) generated by a deep-learning model.
Methods
This retrospective study included the patient-to-patient stress, resting SPECT, and PET datasets of 54 patients. The vPET generation model was trained and validated using 34 cases with over 1200 image pairs using an image-to-image translation network. The SPECT, PET, and vPET images from another 20 cases were blindly scored in the stress and resting states.
Results
The SPECT rest scores at septal and inferior walls (segments #2 and #15) were significantly higher than those of PET. However, no significant differences were observed between the vPET and PET scores. Diagnostic performance of SPECT for detecting PET defect areas were improved with the use of vPET visual scores.
Conclusions
vPET, a new approach for improving ischemic visual score at rest in the well-known attenuated region on SPECT, can be applied as a clinical support tool that provides powerful auxiliary information for myocardial blood flow diagnosis since standalone SPECT is used worldwide.
Enhancing Human Motion Prediction through Joint-based Analysis and AVI Video Conversion
Authors: Xiong Yi , Moqurrab Syed Atif , Ahmad Awais
Published: June 2023

Human joint motion exhibits a high degree of freedom, with different joints capable of moving and rotating in various directions. Consequently, accurately capturing the features of posture motion becomes challenging, resulting in lower prediction accuracy for human joint motion. To address this issue, this paper proposes a novel method for predicting and verifying human motion based on joints using AVI video conversion. The foreground of human motion images in AVI videos is extracted using a Gaussian background model, and the AVI format video is transformed into a 3D video by fusing the foreground and background images. The spatio-temporal weighted attitude motion features of the 3D video frames are extracted and utilized as input for a CNN algorithm. Motion feature vectorization is employed to reduce motion edge detection errors through a spatio-temporal weighted adaptive interpolation method. Subsequently, the motion basis is generated after processing the fusion of attitude edge features. The particle filter algorithm is utilized to establish the human joint motion model, and joint-based motion prediction is conducted based on the motion basis. Experimental results demonstrate that the 3D conversion enhances the background depth of the 2-dimensional AVI video. Additionally, the proposed method extracts motion bases with clear performance, accurate actions, smooth outlines, and non-redundant backgrounds. The prediction results of human movement based on joints exhibit accuracy, with the error in comparison to actual movement falling within a controllable range.

Published: June 2023

Purpose
Colorectal cancer is the third most common cancer worldwide. This study investigated the safety and effectiveness of lipiodol chemoembolization of colorectal artery in animal experiments and a retrospective clinical study for advanced colorectal cancer patients.
Methods
The lipiodol chemoembolization of the posterior mesenteric artery was conducted on six Large White pigs in experimental study. Between September 2021 and June 2022, 12 advanced colorectal cancer patients underwent lipiodol chemoembolization once or twice with 1-month intervals in between.
Results
Following chemoembolization, there were no serious complications, in the pigs. Acute colorectal edema seen on day 1 after the procedure gradually decreased over time and the lipiodol was completely eliminated by day 14. Pathological changes included mucosal and submucosal infiltration by inflammatory cells, local mucosal erosion, and superficial ulceration. None of the patients had any serious adverse events during the peri-interventional period. Mild abdominal pain, mucinous stool, and a sense of urgency and heaviness after chemoembolization were common, but improved in a short time. Overall disease control and objective response rates were 91.6% and 83.3%, respectively.
Conclusion
Lipiodol chemoembolization of the colorectal artery appears to be technically feasible and safe. It may be considered a novel treatment option for patients with advanced colorectal cancers.

Allogeneic hematopoietic cell transplantation (allo-HCT) is curative for myelofibrosis (MF) but assessing risk-benefit in individual patients is challenging. This complexity is amplified in CALR-mutated MF patients, as they live longer with conventional treatments compared to other molecular subtypes. We analyzed outcomes of 346 CALR-mutated MF patients who underwent allo-HCT in 123 EBMT centers between 2005 and 2019. After a median follow-up of 40 months, the estimated overall survival (OS) rates at 1, 3, and 5 years were 81%, 71%, and 63%, respectively. Patients receiving busulfan-containing regimens achieved a 5-year OS rate of 71%. Non-relapse mortality (NRM) at 1, 3, and 5 years was 16%, 22%, and 26%, respectively, while the incidence of relapse/progression was 11%, 15%, and 17%, respectively. Multivariate analysis showed that older age correlated with worse OS, while primary MF and HLA mismatched transplants had a near-to-significant trend to decreased OS. Comparative analysis between CALR- and JAK2-mutated MF patients adjusting for confounding factors revealed better OS, lower NRM, lower relapse, and improved graft-versus-host disease-free and relapse-free survival (GRFS) in CALR-mutated patients. These findings confirm the improved prognosis associated with CALR mutation in allo-HCT and support molecular profiling in prognostic scoring systems to predict OS after transplantation in MF.

Purpose To present an unusual case of a graphite foreign body granuloma causing palatal perforation and review the literature on graphite deposition in the oral mucosa. Methods A 62-year-old female patient presented with a macule on the hard palate clinically consistent with a blue nevus. During excisional biopsy a black nodular mass was found beneath the macule that extended through a tunnel-like palatal deficit towards the nasal cavity. Oroantral communication was verified by a computed tomography scan indicating a diagnosis of malignant melanoma. Results Microscopic examination showed a graphite foreign body granuloma. It was suggested that the core was implanted in a thin area of the palatal bone and the foreign body granuloma caused the tunnel-like resorption. Conclusion Graphite tattoo may be included in the differential diagnosis of solitary pigmented lesions of the oral mucosa and should be excised, as it may cause tissue destruction though the development of a foreign body granuloma reaction.

Published: June 2023

Background
Gut microbiota play a crucial role in defining the immune response. The immune response – gut microbiota interaction is implicated in various human diseases including cancer. Identifying the link between gut microbiota and systemic inflammatory markers, and their association with cancer, will be important to our understanding of cancer etiology.
Results
The current study was performed on 8,090 participants from the population-based Rotterdam Study. We found a significant association (false discovery rate [FDR] ≤ 0.05) between three gut-microbial taxa, namely the family Streptococcaceae, genus Streptococcus, and the order Lactobacillales with lymphocytes. In addition, we identified 95 gut-microbial taxa associated with inflammatory markers (P-value < 0.05). Analyzing the cancer data, we observed a significant association between higher SII levels at baseline (HR: 1.65 [95% CI; 1.10–2.46, P -value ≤ 0.05]) and the higher count of lymphocytes (HR: 1.38 [95% CI; 1.15–1.65, P-value ≤ 0.05]) and granulocytes (HR: 1.69 [95% CI; 1.40–2.03, P -value ≤ 0.05]) with increased risk of lung cancer after adjusting for age, sex, body mass index (BMI), and study cohort. This association was lost for SII and lymphocytes after additional adjustment for smoking (SII = HR:1.46 [95%CI; 0.96–2.22, P -value = 0.07] and lymphocytes = HR: 1.19 [95%CI; 0.97–1.46, P -value = 0.08]). In the stratified analysis, higher count of lymphocytes and granulocytes at baseline were associated with an increased risk of lung cancer in smokers after adjusting for age, sex, BMI, and study cohort (HR: 1.33 [95%CI; 1.09–1.62, P-value ≤ 0.05] and HR: 1.57 [95%CI; 1.28–1.92, P-value ≤ 0.05], respectively).
Conclusion
Our study revealed a positive association between gut-microbiota, higher SII levels and higher count of lymphocytes and granulocytes with an increased risk of developing lung cancer.

Published: June 2023

The strong Ti-O bonds in TiO2 and poor compatibility to Sb2Se3 result in poor performance when used as electron transport layers (ETL) for Sb2Se3 solar cells. Therefore, cadmium sulfide is usually used as a buffer layer to improve its compatibility. In the present work, we deposited a layer of CdS by spin coating method on TiO2 ETL and fabricated TiO2/CdS dual ETL. The CdS layer improved the electronic properties of TiO2 and grain orientation of Sb2Se3 thin films. As a result, the average short circuit current and fill factor of Sb2Se3 solar cells were improved, and the final champion power conversion efficiency was enhanced from 2.6–4.71%. This study supplied a route for the application of titanium dioxide as a broadband gap electron transfer material in Sb2Se3 solar cells.

Published: June 2023

Background
In a previously translated and validated survey, the research team at the center of orthopaedics and trauma surgery cross-culturally adapted non-compliance items of a survey that targeted patients in rehabilitative care in private practice. However, the elements of the previously mentioned questionnaire neither take into account the burdens encountered in an inpatient hospital setting nor the effects of a mobile app-based telerehabilitation program on the early postoperative rehabilitative period. The purpose of this study is to validate elements of a non-compliance survey in an in-hospital setting and discuss aspects of compliance with telerehabilitative physiotherapy in the early postoperative period.
Methods
For this purpose, a literature search was conducted to identify elements that prevent patients from performing their prescribed physical therapy exercises. These items were then evaluated by the expert review technique as described by Ikart. Afterwards, the synthesized survey was handed out to patients for the assessment of the quality of its items.
Results
The results of the expert review technique identified some conceptual and grammatical problems. This lead to the adjustment of some of the elements. The quality of the resulting questionnaire was deemed to be good as patients were able to fully understand the concepts and answer accordingly. A statistical analysis was done to evaluate the responses.
Conclusion
The items of the second questionnaire have proven to be reliable to asses the compliance of patients in an in-hospital setting. These items will be added to the cross-culturally adapted items of a previous questionnaire. The items of the system usability score will be further added to evaluate the experience of patients with an app-based rehabilitation program.

Published: June 2023

Human-machine interface based on force touch panel has attract enormous attention, for the merits of high human-machine interaction efficiency. Many studies and re- searches are devoted to diverse force touch technologies. Broad applications in both actual use and research have been developed, such as 3D Touch and force-based keystroke authentication. The fruitful results are based on the assumption that users’ touch habits remain unchanged along the time, thus a stationary customized force sensing model can be build. However, in long- term use, users’ touch habits changed due to time-drifting and specific-event, causing stationary force sensing model’s performance decreased. To address this issue, a rectified artificial neural network for long-term force sensing in piezoelectric touch panels is presented in this paper. With additional information of touching time and sign of specific-event, the predictions of force level are rectified, achieving an accuracy of 94.79% on long-term data set. The proposed technique enables customized force sensing in long-term use and enhancing human-machine interactive efficiency.

Published: June 2023

This study described the occurrence of food deserts and its relationship with the socioeconomic characteristics of the area. This is an ecological study based on secondary data from the city of Porto Alegre/Brazil. Food deserts were defined based on the density of establishments that sell healthy foods. The socioeconomic variables analyzed were the Health Vulnerability Index, percentage of illiterate people, percentage of people with per capita income of up to half a minimum wage, and percentage of households made up of people who identify as Black, Brown, or Indigenous. Statistical and spatial analyses were conducted using census tracts as units of analysis. Almost half of the census tracts were classified as food deserts (n = 1150/48.3%), with higher concentration in the peripheral areas of the city. Tracts with a high risk of health vulnerability (very high HVI), those with the highest percentage of black and indigenous peoples (Quartile 4), the highest percentage of illiterate people (Quartile 4), and the highest percentage of people living on less than ⅕ minimum wage (Quartile 4), were about twice as likely to be classified as a food desert. For all variables, a dose-response relationship was observed. The results show that in the city of Porto Alegre food deserts were associated with worse environmental and social conditions, and a greater presence of ethnic-racial minority groups. Social and ethnic-racial inequities might shape the city environment, making access to healthy foods more difficult for the most vulnerable populations, with possible repercussions on food consumption, food security and other health outcomes.
Accounting for sex differences as a continuous variable in cancer treatments
Authors: Rubin Joshua , Yang Wei
Published: June 2023

The significant sex differences that exist in cancer mechanisms, incidence, and survival, have yet to impact clinical practice. We propose that one barrier to translation is that sex differences in cancer phenotypes resemble sex differences in height: highly overlapping, but distinct, male and female population distributions that vary continuously between female- and male- skewed extremes. A consequence of this variance is that sex-specific treatments are rendered unrealistic, and our translational goal should be adaptation of treatment to the variable sex-effect on targetable pathways. To develop a tool that could advance this goal, we applied a Bayesian Nearest Neighbor (BNN) analysis to 8370 cancer transcriptomes from 26 different adult and 4 different pediatric cancer types to establish patient-specific Transcriptomic Indices (TI). TI precisely positions a patient’s whole transcriptome on axes of mechanistic phenotypes like cell cycle signaling and immunity that exhibit skewing in the cancer population relative to sex-identified extremes (poles). Importantly, the TI approach reveals that even when TI values are identical, underlying mechanisms in male and female individuals can differ in identifiable ways. Thus, cancer type, patient sex, and TI value provides a novel and patient- specific mechanistic identifier that can be used for precision cancer treatment planning.

Published: June 2023

The spatiotemporal fluctuation of Surface Soil Moisture (SSM) is important for prediction of weather, modeling of hydrological cycle, water management, agricultural managing and making strategy. Optical remote sensing has demonstrated significant promise for precise surface soil moisture estimate. The study aimed to estimate the moisture content in the upper layer of agricultural fields using Landsat 8 OLI, Sentinel-2A multi-spectral satellite data as well as TVDI [Temperature Vegetation Dryness Index] data. The spatial resolution of the Landsat OLI and Sentinel-2A images was 30m and 10m, respectively. The spectral Thermal Infrared (TIR 10.9µm ), TIR (10.9µm) and along with the Short-Wave-Infrared (SWIR 2.2µm) band of the Landsat 8 and the Shore-Wave-Infrared (SWIR 2.2 µm) band of sentinel 2B satellite imagery was utilized to estimate how moist was topsoil of the agricultural lands. The soil moisture estimates using remote sensing based model were acquired and compared with in-situ soil moisture. In a depth of 10cm below the surface, the field-based soil moisture was measured. Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST) and TVDI were measured to estimate moisture content. The reflectance values of the TVDI show over the study area generally low, with the values ranging from -0.07 to 1.37. The statistical tests of TVDI values and gravimetric soil moisture values presented a positive correlation with RMSE= 0.17. The results of the study can give insight of better hydrological modeling, management of agriculture and policy making. However, further research is required to validate the methodology over a larger geographical area and to evaluate the preciseness of the assessed SSM at various depths of the soil.

Authors: Yang Zhe , Xue Xia , Li WangLin , Li Chen
Published: June 2023

Geotextile layers are arranged on and below the geomembrane to prevent the geomembrane from being punctured and damaged. The geotextile not only plays a role in physical protection, like anti-puncture but also makes a great difference to the mechanical properties of the geomembrane’s air expansion deformation. In this paper, the bulging deformation of geotextile is simplified as spherical bulging deformation under ring-restrained conditions. Using the special bulging deformation test equipment, the bulging deformation experiment of geotextile is realized, the main factors affecting the bulging deformation are analyzed, the law of bulging deformation and failure of geotextile is summarized, the failure mechanism of geotextile and the Influence of geotextile on the properties of geomembrane are discussed, and the following conclusions are drawn. The failure of bulging deformation of geotextiles belongs to tensile failure, which is characterized by fast speed and high strength. The typical failure mode is spindle-shaped cracks distributed along the crown, whose failure mechanism belongs to tensile failure produced in weak areas. The bulging deformation of the geotextile shows nonuniformity, with the largest deformation at the crown top and the smallest deformation at the ring constraint. When the geotextile is covered on the geomembrane, bulging pressure is shared by both the geomembrane and the geotextile. At the initial deformation stage, the geomembrane replaces it, and then the geotextile bears more internal pressure and plays a decisive role till destruction.
Temperature and humidity sensor monitoring of directly buried cable based on temperature field distribution simulation of power cable
Authors: Lin Menghao , Shi Qian , Wang Tianle
Published: June 2023

Power cable is a piece of major transmission equipment, and its operating temperature as a major factor determines whether the cable system can operate safely and reliably and the current-carrying capacity. Therefore, it is of great significance to master the real-time temperature and the distribution of the power cable core. During the aging of cable insulation, temperature, as a major factor, directly determines the aging rate. One of the basic parameters on the power cable is the ampacity. If the ampacity is high, the cable will be overloaded. In this paper, the thermal circuit method is used to construct and calculate the cable, and the whale algorithm is used to estimate the temperature of the cable conductor. The conductor is estimated accurately within the allowable error range. The results are compared with the results of finite element simulation to verify the effectiveness of the finite element method. Through the experimental analysis, the model is established according to the cable trench on the spot. The steady-state temperature field is calculated through parameter setting. The average packet loss rate is 0.066 %, and the relative error is 0.32 %, which proves that this study can optimize the communication mode of the network and achieve a better monitoring effect. The method realizes the real-time temperature rise prediction of the cable core conductor by using the temperature rise of the outer skin. It can provide a certain theoretical basis for the online monitoring and engineering practical application of the cable core temperature and has practical significance.

19. yüzyılda sanayi alanındaki gelişmeler insan yaşamında değişimi beraberinde getirmiştir. Bu değişim sanat dallarında olduğu gibi müzikte de kendini göstermiş Ulusalcılık akımının da etkisiyle besteciler kendi kültürüne ve ülkesine duyduğu özlemi, sevgiyi eserlerine yansıtmışlardır. Böylelikle bazı müzikler besteci ve ülkesinin kültürü arasında çok güçlü bir bağ oluşmasını sağlamıştır. Bu bağ Chopin’in müziklerinde mazurkalar şeklinde görülmektedir. Mazurkalar, 16. yy’da Polonya’nın Varşova kenti yakınlarındaki Mazovia bölgesinde yaşayan Mazurlar tarafından ortaya çıkarılmış bir halk dansıdır. Mazurka türünün günümüzde çalgı dağarında özellikle de piyano repertuvarında hala çalınıyor ve biliniyor olmasında Frederic François Chopin’in çok büyük katkısı vardır. Çoğunlukla piyano eserleri besteleyen F. F. Chopin, vatan sevgisini, ulusuna bağlılığını ayrıca özlemlerini mazurka ve polonez türleri üzerinde gerçekleştirdiği çalışmalarla ifade etmiştir. Bu araştırmada F. F. Chopin’in Op. 6 No.1 Mazurkası çalıcıya eserin müzikal ifadesinde yardımcı olması amacıyla formsal açıdan ayrıntılı incelenmiştir.

Birçok sanat dalının yanı sıra tekstil sanatında da çok boyutluluk anlayışı ile yeni malzeme ve teknik arayışlara yönelim söz konusu olmuştur. 1962 yılında I. Lozan Tapestry Bienali tekstil sanatı örneklerinde ilk defa geleneksel tapestry anlayışının dışına çıkarak farklı sergileme biçimleri büyük ses getirmiştir. Tekstil sanatının plastik sanatlar çerçevesinde kabul görmesiyle serbest tekstiller, tapestry ve lif sanatı gibi kavramlar iç içe geçmiştir. Güncel sanatta bu eserler sanatçıların yaklaşımlarına bağlı olarak birçok sanat disiplini çerçevesinde ele alınmaktadır. Enstalasyon sanatı, farklı disiplinlerin yanı sıra tekstil sanatında en çok kullanılan ifade ve temsil araçlarından birisidir. Bu makale ile 21.yy lif sanatının enstalasyon sanatındaki sergileme biçimlerinin incelenmesi ve disiplinlerarası çalışan sanatçıların örnekleriyle mekan, nesne ve izleyici ilişkisinin ortaya konulması amaçlanmıştır. Seçilen 10 adet güncel lif sanatına ait eserin enstalasyon sanatındaki uygulamaları ve izleyici eser etkileşimi kavramsal düzeyde ele alınmıştır.

Azerbaycan Hanlıklar dönemindeki milli kimlik, erkek milli kıyafetlerinin her alanında kendisini göstermektedir. Hanlıklar zamanında erkek milli kıyafetlerinin modelleri, kumaş ve süsleme özellikleri, giysilere ait biçim ve karakter özellikleri irdelendiğinde bunlar arasında süregelen çeşitli bağların olduğu ve bu bağların süreç içerisinde kendisini modern kültüre entegre etmeye çalıştığı saptanmaktadır. Yüzyıllar boyunca Azerbaycan ile diğer milletler arasında kurulan etkileşimler özellikle farklı kültürel miras kimliklerinin de Azerbaycan’da Hanlık döneminde erkek milli kıyafetlerine tesir ettiği görülür. Bu tesirin sembolizasyonu ve somutlaşması kıyafetler üzerinde kendine bir yer tutturmuş. Azerbaycan kimliğinin erkek çizgileri aracılığıyla nasıl miras alındığı ve korunduğu belirgin bir şekilde ortaya çıkmaktadır. Özellikle Hanlıklar döneminde farklı kültürel miras kimliklerinin gösterilmesi süreç içerisinde bu milli giyimlerin yerini modern giysilere bırakması geleneksel kültürden kopmadan yeni yöntemler ve teknikler kullanılarak çağa uygun giysilerin tasarlanabilmesine olanaklar hazırlamaktadır.

Introducción: a medida que aumenta la expectativa de vida y la incidencia de enfermedades crónicas y terminales en América Latina, también crece el número de pacientes que requieren cuidados paliativos, y el personal especializado para su manejo aun es limitado, siendo los médicos generales y cuidadores quienes deben apoyar el manejo del dolor. Objetivos: brindar herramientas teóricas y prácticas, tanto a médicos generales como a los parientes de pacientes que requieran cuidados paliativos, que les faciliten realizar un adecuado manejo del dolor en este tipo de pacientes. Materiales y métodos: se realizó una revisión narrativa a partir de la sistematización de una búsqueda de diferentes bases de datos, publicaciones de sociedades de cuidados paliativos y anestesia, además de literatura gris. Resultados: entre los principales resultados se vio que la mayoría de los pacientes con enfermedades terminales presentan dolor moderado o severo entre sus síntomas principales. De estos un porcentaje importante no presentaba un control adecuado del dolor al momento de fallecer, principalmente por un uso inadecuado de los opioides, entre otros por miedo y desconocimiento por parte de los médicos tratantes y los cuidadores. Los opioides como grupo farmacológico presentan múltiples ventajas para el uso en cuidados paliativos, entre ellos la posibilidad de titularlos a necesidad, realizar rotación de opioides y disponer de múltiples vías de administración. Discusión: a pesar de la amplia disponibilidad de opioides continúa habiendo barreras significativas para un adecuado manejo del dolor al final de la vida, entre ellos la falta de conocimiento por parte de los médicos generales.

This document is written for those who wish to contribute to the GTAP data base, whether by providing an input-output table for a country not separately represented in the data base, or by updating the table for a region that is already represented. It provides specifications and advice on the structure of the table, sectoral classification, treatment of imports, and other key points. It also describes what we at the Center for Global Trade Analysis do once we receive your table. This version has been revised for use by contributors to release 11 of the GTAP data base. In particular, all concordances are to the revised GTAP sectoral classification.
Implementing Systematic Sensitivity Analysis Using GEMPACK
Authors: Pearson Ken , Arndt Channing
Published: June 2023

In economic simulation, results often hinge crucially on values of key exogenous inputs (the values of the parameters of the model and the shocks applied). Computational burden has, in the past, hindered systematic investigation of the impacts of variations in these key exogenous inputs. In this document, practical methods for conducting systematic sensitivity analysis for any model implemented using the GEMPACK suite of software are documented. The procedures described here are based on GTAP Technical Paper number 2 which sets out the theory behind the Gaussian quadrature methods on which the automated procedure is based. The procedures allow modellers to obtain estimates of the means and standard deviations of any endogenous variables of their model. The model only needs to be solved a relatively modest number of times (usually only 2N times if N exogenous inputs are varying); this is considerably fewer than the number of solves required by Monte Carlo methods. The procedure documented here fully automates solving the model as often as is necessary; once the user sets it up and starts it running, no further intervention is required. The document spells out the assumptions which must be made about the distribution of the exogenous inputs for the methods described to be valid. Five examples of systematic sensitivity computations are presented and the accompanying software allows modellers to work through these examples while reading the document. This should leave readers fully prepared to analyse the sensitivity of results for any model implemented in GEMPACK.
Decomposing Welfare Changes in GTAP
Authors: Huff Karen , Hertel Thomas
Published: June 2023

This paper develops a complete decomposition of the change in global welfare in the GTAP model. In particular, this money metric change is broken down into component parts, each of which relates to a quantity change interacting with a distortion in the model. This enables the user to assess, for example, how much of the gains from trade reform are attributable to a given commodity and/or a given region. The commodity and region specific changes in allocative efficiency can be further decomposed by transaction/tax instrument. We find that this greatly facilitates the presentation and analysis of results from GTAP. We motivate the derivation of this decomposition with the case of a one region, three commodity, analogue to the GTAP model. This permits us to focus on purely allocative efficiency effects (no terms of the trade changes). Extension to the multiregion model adds the prospect of terms of trade effects on regional EV, and the multiregion decomposition isolates the contribution of tradable price changes to regional welfare. This is demonstrated in a 3 region, 3 commodity example. Finally, we offer a more complete decomposition which takes into account the impact of changes in endowments and technology on regional welfare. This revised (2001) version introduces a number of important changes to the original (1996) paper. In particular, we build on the new final demand structure for GTAP proposed by McDougall (2001). This includes explicit recognition of changes in the marginal utility of income, as well as a per capita decomposition. We also take account of version 5.0 changes in the standard GTAP model, including the introduction of multiple international margins commodities.
Introducing Monopolistic Competition into the GTAP Model
Authors: Hertel Thomas , Swaminathan Padma
Published: June 2023

This technical paper documents one approach to incorporating monopolistic competition into the GTAP model. In this framework, consumer preferences are heterogeneous, leading to an apparent "love of variety" in the aggregate utility function for each region. The more heterogeneous are preferences, the smaller the elasticity of substitution in the aggregate utility function, and the greater the value placed on the addition of new varieties. The same is true for firms, which experience lower unit costs for differentiated, intermediate inputs, as the number of varieties on offer increases. In order to meet the diverse needs of consumers, firms differentiate their products through research and development (R&D) as well as advertising activities. These costs are assumed to be invariant to the total volume of sales for a given variety of product. With production occurring at constant returns to scale, this gives rise to declining average total costs. A zero profits equilibrium in this model is characterized by firms marking up their price over marginal costs by an amount sufficient to cover the fixed costs associated with establishing a new variety in the marketplace. Since the optimal markup is itself determined by the elasticity of substitution among varieties, this establishes a direct relationship between fixed costs and the degree of preference heterogeneity. The main differences between the monopolistically competitive sectors and the traditional GTAP sectors may be summarized as follows: We introduce two new variables: n, the number of firms in the industry and qof, the output per firm. Minimum expenditure and unit costs are declining in n. Average total costs are declining in output per firm. Unlike the Armington specification, foreign and domestic firms compete directly in the representative consumer's utility function. We illustrate this framework with a 2 commodity/3 region example in which we eliminate US antidumping duti
A New Regional Household Demand System for GTAP
Authors: McDougall Robert
Published: June 2023

The GTAP model, versions 4.1 and lower, suffers from some defects in the implementation of the regional household demand system. Most seriously, the upper level of the demand system assumes that each regional household faces a fixed price for utility from private consumption. But with a private consumption demand system of the CDE form, the price of utility from private consumption depends on the level of private consumption expenditure. With no fixed price for utility from private consumption, the familiar Cobb-Douglas demand system does not apply. Accordingly, the upper-level demand equations are in error. Furthermore, utility and equivalent variation are wrongly computed in simulations with non-standard settings for the CDE expansion parameters. Even with the standard settings, in multi-step simulations the utility and equivalent variation computations are inexact. The welfare decomposition inherits the defects of the equivalent variation computation. In removing these defects we revise in passing some minor misfeatures of the old treatment: Firstly, we treat the entire final demand system as the demand system of a representative household, rather than a conglomeration of representative and region-wide demand systems (subsection 2.6). Secondly, we provide a new facility for shifting the allocation of regional income exogenously by modifying rather than overriding the final demand system (subsection 2.14). Finally, we eliminate an uninterpretable \nuisance term" from the decomposition of equivalent variation (subsection 4.3).
