Tinjauan Literatur : Underground Economy dan Perpajakan Prostitusi
Authors: Hazmi Raldin 
Published: December 2024

Prostitution is actually an undergorund economy that is difficult to detect, because every commercial sex worker in this business is difficult to distinguish from ordinary people in general. In terms of taxation, tax is designed not to recognize assets obtained from legal activities, and from illegal activities, no matter whether the income is obtained from corruption, prostitution, human trafficking, illegal arms trade and even narcotics. As long as it is known that there is an increase in income or enjoyment, the state has the right to collect taxes. However, the relationship between prostitution and taxes is very sensitive. Prostitution business has a huge potential. Exploring the potential of this business if done massively will increase tax revenue quite significantly, but there are externalities that DGT must face. In this case, DGT must also use the moral point of view prevailing in society. Taxing something illegal and immoral will indirectly give an opinion to the public that the state legalizes the activity.

Prostitusi sejatinya merupakan undergorund economy yang sulit dideteksi keberadaannya, karena setiap pekerja seks komersial yang ada di bisnis ini sulit dibedakan dengan masyarakat biasa pada umumnya. Di lihat dari sisi perpajakan, Pajak didesain dengan tidak mengenal harta yang didapat dari aktivitas yang legal, dan dari aktivitas ilegal, tidak peduli apakah penghasilan tersebut didapat dari hasil korupsi, prostitusi, perdagangan manusia, perdagangan senjata ilegal bahkan narkotika. Selama diketahun terdapat penambahan penghasilan atau kenikmatan, maka negara memiliki hak untuk memungut pajak. Namun hubungan antara prositutsi dengan pajak sangatlah sensitif. Bisnis Prostitusi memang memiliki potensi yang sangat besar. Penggalian potensi bisnis ini jika dilakukan secara masif maka akan meningkatkan penerimaan pajak cukup signifikan, akan tetapi terdapat ekternalitas yang harus dihadapi DJP. Dalam hal ini DJP juga harus menggunakan sudut pandang moral-moral yang berlaku di masyarakat Mengenakan pajak terhadap sesuatu yang ilegal dan amoral akan memberikan opini secara tidak langsung kepada masyarakat bahwa negara melegalkan aktivitas tersebut.

Published: December 2024

Objectives. Much of the research in deep learning has focused on studying mappings between finite-dimensional spaces. While hydrodynamic processes of gas filtration in underground storage facilities can be described by partial differential equations (PDE), the requirement to study the mappings between functional spaces of infinite dimension distinguishes this problem from those solved using traditional mapping approaches. One of the most promising approaches involves the construction of neural operators, i.e., a generalization of neural networks to approximate mappings between functional spaces. The purpose of the work is to develop a neural operator to speed up calculations involved in hydrodynamic modeling of underground gas storages (UGS) to an acceptable degree of accuracy.Methods. In this work, a modified Fourier neural operator was built and trained for hydrodynamic modeling of gas filtration processes in underground gas storages.Results. The described method is shown to be capable of successful application to problems of three-dimensional gas filtration in a Cartesian coordinate system at objects with many wells. Despite the use of the fast Fourier transform algorithm in the architecture, the developed model is also effective for modeling objects having a nonuniform grid and complex geometry. As demonstrated not only on the test set, but also on artificially generated scenarios with significant changes made to the structure of the modeled object, the neural operator does not require a large training dataset size to achieve high accuracy of approximation of PDE solutions. A trained neural operator can simulate a given scenario in a fraction of a second, which is at least 106 times faster than a traditional numerical simulator.Conclusions. The constructed and trained neural operator demonstrated efficient hydrodynamic modeling of underground gas storages. The resulting algorithm reproduces adequate solutions even in the case of significant changes in the modeled object that had not occurred during the training process. The model can be recommended for use in planning and decision-making purposes regarding various aspects of UGS operation, such as optimal control of gas wells, pressure control, and management of gas reserves.
Analytical method for analyzing message transmission processes in FDDI networks for digital substations
Authors: Leontyev A. S. , Zhmatov D. V. 
Published: December 2024

Objectives. To develop analytical approaches for the evaluation of probability-time characteristics and fiber distributed data interface (FDDI) network performance with the marker access method, thus enabling communication processes for digital electrical substations to be automated.Methods. The authors used theory reliability methods, random process theory, mass maintenance theory, the Laplace–Stieltjes transformation for inferring functional equations and the probability-time characteristics calculation for the information transfer processes with the occurring failures.Results. We conducted a numerical study of packet transfer processes between central processing stations in the FDDI network. We considered the processes of discrete information exchange between electronic devices in the system of electrical digital substations. These included the main technological operations and electrical digital substations operator performed when preparing reports. We described the different modes of operation, both for the individual electrical digital substation and for the system. The authors calculated node loading dependencies, FDDI network performance and temporal characteristics of the packet transfer processes on the incoming message flow intensity and the transmission medium reliability. We conducted a functional analysis of the FDDI networks on two fiber-optic rings which form the main and redundant path of data transfer between the network nodes, significantly increasing network resiliency. The objective of the study was to analyze the information transfer processes in FDDI networks with an accent on ensuring the transmission medium reliability.Conclusions. We were able to establish the existence of the critical operating network region, which leads to a sharp increase in node load and temporal characteristics, while performance reaches its maximum value and then sharply decreases. We propose the exchange of discrete messages to reflect the electronic devices state and information messages of operator between various remotely spaced electrical digital substation with the FDDI fiber-optic network.
Reflections of linearly polarized electromagnetic waves from a multilayer periodic mirror
Authors: Nurligareev D. Kh. , Nedospasov I. A. , Kharitonova K. Yu. 
Published: December 2024

Objectives. The purpose of the article is to carry out a theoretical and experimental study of the angular reflection spectrum of linearly polarized electromagnetic waves from a multilayer periodic mirror on a transparent substrate to exact analytical expressions for reflection and transmission coefficients generalizing the cases of incidence of plane transverse electric (TE) and transverse magnetic (TM) modes on limited periodically structured media with a stepped refractive index profile.Methods. The theoretical analysis of the reflection problem is based on the search for exact analytical solutions in the form of Floquet–Bloch waves presented in the form of inhomogeneous waves in the domain of periodically structured media. On the basis of the possible existence of a single Floquet–Bloch wave in a limited onedimensional photonic crystal, it is proposed to search for exact solutions of the wave equation in the form of a linear combination of inhomogeneous waves propagating in different directions. By using the canonical forms of the considered periodic structures, it is possible to carry out the simple transition from the case of TE polarization to TM type in dispersion relations and expressions for the angular reflection spectrum.Results. Cases of reflection of linearly polarized radiation are considered for the following cases: a flat boundary of two dielectrics, a thin plane-parallel plate, and a multilayer dielectric mirror. Exact analytical expressions for the reflection and transmission coefficients generalizing the cases of incidence of TE and TM polarizations waves on a limited one-dimensional photonic crystal are obtained. The transmission coefficients of a plane TE wave from a multilayer dielectric mirror sputtered on thin glass were experimentally measured.Conclusions. A quantitative and qualitative agreement of experimental measurements of the transmission coefficient of a plane wave incident from a half-space on a confined photonic crystal with theoretical calculations is obtained. The obtained expressions for the transmission coefficient of a confined one-dimensional photonic crystal, which are shown to be determined by the interference of Floquet–Bloch waves presented in the form of inhomogeneous waves, can be reduced to a form analogous to the expression for the value of the transmission coefficient of a traditional Fabry–Pérot interferometer. In the case of TM polarization, when the Brewster condition is fulfilled at the interlayer boundaries, the Floquet–Bloch wave has the form of homogeneous plane waves in the layers of a photonic crystal.
Development of model representations of thermal reaction viscoelastic bodies on the temperature field
Authors: Kartashov E. M. 
Published: December 2024

Objectives. In recent decades, the relevance of research into the thermal response of solids to a temperature field has increased in connection with the creation of powerful energy emitters and their use in technological operations. There is a significant number of publications describing these processes using mathematical models of dynamic or quasi-static thermoelasticity, mainly for most technically important materials that obey Hooke’s law. However, at elevated temperatures and higher stress levels, the concept of an elastic body becomes insufficient: almost all materials exhibit more or less clearly the phenomenon of viscous flow. The real body begins to exhibit elastic and viscous properties and becomes viscoelastic. A rather complex problem arises: the development of dynamic (quasistatic) thermoviscoelasticity within the framework of the corresponding mathematical models of classical applied thermomechanics and mathematics. The purpose of the work is to consider the open problem of the theory of thermal shock in terms of a generalized model of thermoviscoelasticity under the conditions of classical Fourier phenomenology on the propagation of heat in solids. Three types of intense heating are considered: temperature, thermal, and medium heating. Intensive cooling modes can be equally considered. The task is posed: to develop model representations of dynamic (quasi-static) thermoviscoelasticity that allow accurate analytical solutions of the corresponding boundary value problems on their basis. This direction is practically absent in the scientific literature.Methods. Methods and theorems of operational calculus were used.Results. Model representations of the thermal response of viscoelastic bodies using the proposed new compatibility equation in displacements have been developed.Conclusions. New integro-differential relations are proposed based on linear rheological models for the Maxwell medium and the Kelvin medium, including both dynamic and quasi-static models for viscoelastic and elastic media, generalizing the results of previous studies. The proposed constitutive relations of the new form are applicable to describe the thermal response of quasi-elastic bodies of a canonical shape simultaneously in three coordinate systems with a system-defining parameter, which makes it possible to identify the influence of the topology of the region on the value of the corresponding temperature stresses.
Grounding-IQA: Multimodal Language Grounding Model for Image Quality Assessment
Authors: Chen Zheng , Zhang Yulun 
Published: December 2024

The development of multimodal large language models (MLLMs) enables the evaluation of image quality through natural language descriptions. This advancement allows for more detailed assessments. However, these MLLM-based IQA methods primarily rely on general contextual descriptions, sometimes limiting fine-grained quality assessment. To address this limitation, we introduce a new image quality assessment (IQA) task paradigm, GROUNDING-IQA. This paradigm integrates multimodal referring and grounding with IQA to realize more fine-grained quality perception. Specifically, grounding-IQA comprises two subtasks: grounding-IQA-description (GIQA-DES) and visual question answering (GIQA-VQA). GIQA-DES involves detailed descriptions with precise locations (_e.g._, bounding boxes), while GIQA-VQA focuses on quality QA for local regions. To realize grounding-IQA, we construct a corresponding dataset, GIQA-160K, through our proposed automated annotation pipeline. Furthermore, we develop a well-designed benchmark, GIQA-Bench. The benchmark comprehensively evaluates the model grounding-IQA performance from three perspectives: description quality, VQA accuracy, and grounding precision. Experiments demonstrate that our proposed task paradigm, dataset, and benchmark facilitate the more fine-grained IQA application. Code: https://github.com/zhengchen1999/Grounding-IQA.

Published: December 2024

La mayor incidencia de infecciones por bacilos gram negativos multirresistentes, especialmente en áreas críticas, ha requerido revalorizar la utilidad de viejos antibióticos como el colistín, del grupo de las polimixinas. Su uso en pacientes quemados, sobre todo en población pediátrica, ha sido poco estudiado. Objetivo: Evaluar la eficacia y toxicidad neurológica y renal del colistín en menores de 18 años internados en una unidad de quemados en un hospital de alta complejidad.Pacientes y Método: estudio de cohorte prospectivo no controlado. Se incluyeron todos los pacientes quemados que recibieron colistín en el período comprendido entre mayo 2022 y octubre 2023 en forma empírica o por infección documentada. Se evaluaron datos demográficos, características de la quemadura, aislamiento microbiológico, tratamiento y evolución. Cada 72 horas se evaluó la función renal y diariamente las manifestaciones neurológicas. Resultados: Se incluyeron 15 pacientes que recibieron colistín con un total de 23 indicaciones. Mediana de edad: 6 años (rango (r): 0,7 a 15,0). Mediana de dosis de colistín: 5,5 mg/kg/día (r: 4,0-7,5). En 10 indicaciones fue un tratamiento dirigido a un microorganismo documentado y en el resto fue empírico. No hubo ningún caso de nefrotoxicidad ni de alteraciones neurológicas. Todos los pacientes evolucionaron favorablemente, excepto uno que falleció por causas distintas a la infección y administración de colistín. Conclusiones: el colistín parece ser seguro y eficaz en el manejo de pacientes quemados. Se requieren trabajos prospectivos, con grupo control y con mayor número de pacientes, además de estudios farmacocinéticos, para avalar fehacientemente estos resultados.

Published: December 2024

En mayo de 2020 la OMS alertó de la ocurrencia de un síndrome inflamatorio multisistémico asociado a la infección por COVID-19 en población pediátrica. Objetivo: Determinar la seguridad de la vacuna contra SARS-CoV-2 en pacientes pediátricos que previamente han sido hospitalizados por síndrome inflamatorio multisistémico asociado a COVID-19 (SIM-C). Pacientes y Método: Estudio descriptivo en pacientes con diagnóstico de SIM-C egresados del Hospital Dr. Exequiel González Cortés, Santiago, Chile, entre marzo de 2020 y diciembre de 2022 que posteriormente recibieron vacuna contra SARS-CoV-2. Se revisó número de dosis, fecha de cada vacunación, distancia temporal respecto al diagnóstico de SIM-C y el tipo de vacuna recibida en el periodo estudiado. Se aplicó un cuestionario, sobre síntomas y eventos adversos presentados por los pacientes en el periodo de hasta 12 semanas posterior a cada vacunación, así como síntomas sugerentes de recurrencia de SIM-C. Se excluyeron a pacientes que no fue posible contactar, no quisieron participar o no eran susceptibles de vacunar. Resultados: Se incluyeron 50 pacientes, cuya mediana de edad fue de 5,2 años. De estos parel 58% eran del sexo masculino y 68 % requirió ingreso a unidad de paciente crítico. El 82% recibió al menos 1 dosis de vacuna contra SARS-CoV-2. El tiempo (mediana) entre el diagnóstico del SIM-C y la primera dosis de la vacuna fue de 15 meses (0-24). No se informaron eventos adversos graves ni recurrencia de SIM-C. Conclusión: La vacunación contra el SARS-CoV-2 presenta un perfil de seguridad adecuado, independientemente de la edad, manifestación clínica del SIM-C, evolución, tipo de vacuna e intervalo entre la enfermedad y la vacunación. El intervalo para vacunar después de un SIM-C podría ser menor a 3 meses.

Published: December 2024

La ataxia episódica tipo 2 (AE2) es un trastorno autosómico dominante poco común y subdiagnosticado, causado por variantes patogénicas de CACNA1A. AE2 se presenta con episodios de ataxia que duran horas y puede ir acompañado de mareos, y nistagmo. La acetazolamida es eficaz en la mitad de los casos, y se ha utilizado una combinación de acetazolamida y levetiracetam para tratar a algunos pacientes adultos. Objetivo: Reportar 3 pacientes portadores de AE2, tratados con éxito con una combinación de acetazolamida y levetiracetam. Caso Clínico: Tres miembros de una familia tuvieron episodios recurrentes de inestabilidad de la marcha, que duraban minutos y ocurrían varias veces por semana. Se evidenció heterogeneidad fenotípica intrafamiliar en manifestaciones clínicas tales como discapacidad intelectual, migraña, epilepsia y nistagmo. Después de un extenso estudio y un seguimiento de más de cinco años, se identificó una nueva variante patogénica en CACNA1A, NM_001127221.1:c.1580T>G (p.Leu527*), asociada con AE2. Los tres pacientes respondieron parcialmente al tratamiento con acetazolamida; por lo que se añadió levetiracetam en dosis bajas a dos de ellos, lo que redujo drásticamente los síntomas. Conclusiones: Describimos una familia chilena con AE2. El estudio genético permitió obtener un diagnóstico preciso e iniciar un manejo adecuado con acetazolamida. Como segunda línea, levetiracetam fue eficaz. Se necesitan más estudios para evaluar la eficacia de combinar levetiracetam con acetazolamida en pacientes pediátricos y adultos, o del uso de levetiracetam como monoterapia.
