Seguridad alimentaria como derecho humano. Alcances y limitaciones
Authors: Leal García Roberto Carlos
Published: January 2023

“Toda persona tiene derecho a la alimentación nutritiva, suficiente y de calidad. El Estado lo garantizará.” Este texto consagrado en la Constitución Política de los Estados Unidos Mexicanos tiene particularidades que hacen utópico su cumplimiento ya que debe tomarse en cuenta que, en la actualidad, existen casi 47 millones de personas que no pueden alimentarse diariamente. Debe reconocerse que mientras no se tutele de manera correcta este derecho humano a través de las garantías jurídicas correctas, no solamente por medio de políticas públicas ineficaces, esta situación no será eliminada sino solamente serán promesas que agravan la situación del hambre en México.
3D Quantum-inspired Self-supervised Tensor Network for Volumetric Segmentation of Medical Images
Authors: Konar Debanjan , Bhattacharyya Siddhartha , Gandhi Tapan Kumar , Panigrahi Bijaya Ketan , Jiang Richard
Published: January 2023

This paper introduces a novel shallow 3D self-supervised tensor neural network for volumetric segmentation of medical images with merits of obviating training and supervision. The proposed network is referred to as 3D Quantum-inspired Self-supervised Tensor Neural Network (3D-QNet). The underlying architecture of 3D-QNet is composed of a trinity of volumetric layers viz. input, intermediate and output layers inter-connected using an S-connected third-order neighborhood-based topology for voxel-wise processing of 3D medical image data suitable for semantic segmentation. Each of the volumetric layers contains quantum neurons designated by qubits or quantum bits. The incorporation of tensor decomposition in quantum formalism leads to faster convergence of the network operations to preclude the inherent slow convergence problems faced by the classical supervised and self-supervised networks. The segmented volumes are obtained once the network converges. The suggested 3D-QNet is tailored and tested on the BRATS 2019 Brain MR image data set and Liver Tumor Segmentation Challenge (LiTS17) data set extensively in our experiments. 3D-QNet has achieved promising dice similarity as compared to the intensively supervised convolutional network-based models like 3D-UNet, Vox-ResNet, DRINet, and 3D-ESPNet, showing a potential advantage of our self-supervised shallow network on facilitating semantic segmentation.
Unified Analysis on L1 over L2 Minimization for signal recovery
Authors: Tao Min , Zhang Xiao-Ping
Published: January 2023

In this paper, we carry out a unified study for L_1 over L_2 sparsity promoting models, which are widely used in the regime of coherent dictionaries for recovering sparse nonnegative/arbitrary signal. First, we provide the exact recovery condition on both the constrained and the unconstrained models for a broad set of signals. Next, we prove the solution existence of these L_{1}/L_{2} models under the assumption that the null space of the measurement matrix satisfies the $s$-spherical section property. Then by deriving an analytical solution for the proximal operator of the L_{1} / L_{2} with nonnegative constraint, we develop a new alternating direction method of multipliers based method (ADMM$_p^+$) to solve the unconstrained model. We establish its global convergence to a d-stationary solution (sharpest stationary) and its local linear convergence under certain conditions. Numerical simulations on two specific applications confirm the superior of ADMM$_p^+$ over the state-of-the-art methods in sparse recovery. ADMM$_p^+$ reduces computational time by about $95\%\sim99\%$ while achieving a much higher accuracy compared to commonly used scaled gradient projection method for wavelength misalignment problem.

Authors: Gupta Rishabh , Saxena Deepika , Gupta Ishu , Makkar Aaisha , Singh Ashutosh Kumar
Published: January 2023

This letter proposes a novel malicious user prediction model based on quantum machine learning that estimates the vicious entity present in the communication system precedently before allocating the data in the distributed environments. The proposed model scrutinizes the behavior of each user and estimates probable data breaches using a developed malicious user predictor unit. The model computes essential scores associated with each user request for the learning process of the prediction unit by generating training samples. The predictor unit exploits the computational and behavioral properties of Qubits and Quantum gates for the accurate prediction of the malicious user with high precision to grant access to non-malicious data requests only. The experimental evaluation and comparison of the proposed model with state-of-the-art methods reveal that it significantly improves the security of the system up to 33.28%.
ChatGPT on Characteristic Mode Analysis
Authors: Ghosal Sandip
Published: January 2023

ChatGPT is a natural language processing model based text-to-text AI interactive conversation platform developed using generative pre-trained architecture (GPT) by OpenAI. The present study utilizes the ChatGPT to understand the characteristic mode analysis-a popular numerical technique for antenna and array design in recent times. It was noted that ChatGPT can provide a basic understanding of characteristic mode theory in an elegantly simplified text language. However, being a data-driven model, its accuracy strongly depends on the data used to train the model, low accuracy is noted on predicting the names of the reference papers or related journal authors correctly in most cases. Another major limitation of using chatGPT is the lack of plagiarism check as it chooses sentences based on the training data resources. 
Design of Dispersion-Reconfigurable Phaser using PIN-Diode Loaded Stepped-Impedance Line
Authors: Lei Haoling , Huang Yi , Duan Chaijie , Zhang Qingfeng
Published: January 2023

This paper proposes a dispersion-reconfigurable reflection-type phaser based on PIN-diode loaded stepped-impedance microstrip line. By configuring `ON' and `OFF' states of PIN-diode, the proposed phaser exhibits positive-slope, negative-slope, and zero-slope linearly dispersive group delay responses.  For proof-of-concept demonstration, we use line connection/disconnection to mimic ON/OFF states of PIN diode. Three prototypes are hence fabricated to represent the three different states. The experimental results agree well with the expected responses, which finally validate the proposed concept.

A simple, four-parameter formula is proposed and used to smooth noisy transistors  curves for the purpose of stable extraction of transistor field-effect mobility and threshold voltage.  The proposed smoothing shape function is found to work for  data obtained for short and long transistors, low and high drain voltage, and for TFTs, ET-SOI, and Trigate MOSFETs
Improved Performance and Stability in Overflow Loss Systems via Exchange of Congestion Information
Authors: Wong Eric W. M. , Chan Yin Chi
Published: January 2023

In systems and networks where overflow is penalized, careful planning is required to prevent a small increase in the offered load from suddenly triggering a system collapse. In this work, we consider an overflow loss system where the service time distribution of a request is dependent on the number of overflows. We propose a novel admission control policy for improving the stabilization and performance of such a system based on a new information exchange mechanism (IEM) for congestion information, in which only a small amount of congestion information is carried by each request and is propagated via the overflow of requests. This avoids the need for an external mechanism for propagating congestion information. Furthermore, IEM is fully compatible with trunk reservation, a simple, classical, yet effective method of admission control in overflow loss systems and networks. Despite the very limited amount of communication overhead required by IEM (only a few bits per request), numerical results demonstrate that the combination of IEM with trunk reservation provides greater performance and stability than trunk reservation alone. We also present a computationally efficient analytical performance evaluation method based on IEM and demonstrate numerically that it is asymptotically exact and generally quite accurate. Therefore, the analytical method can be used for system design and planning.
Analytic Model of Quantum Dot LED Current-Voltage Characteristics
Authors: Ahmed Khaled
Published: January 2023

Quantum dot light-emitting diode (QDLED) displays promise superior color gamut with respect to organic light-emitting diode (OLED) displays and liquid-crystal displays (LCDs).  In this paper, for the first time, a data-validated closed-form physics-based expression is derived for the I-V characteristics of QDLEDs. The I-V equation is derived using an approximation scheme which not only brings the previously intractable transport mechanisms back into the fold of analytic tractability but emphasizes the underlying physics of each transport mechanism in doing so. The model is shown to fit state-of-the-art experimental data over a large range of operating currents. The model may be used for circuit simulations.
Toward a Nanostructured TeV accelerator: The DLA Nanostructured Cyclotron
Authors: Ghaderi Salar
Published: January 2023

Particle accelerators and their key characteristics including size, energy scale, gradient, and efficiency are at the core of any revolutionary development in various fields including particle physics,  bioimaging, and many more. [2,3,4] Recently, linear accelerators benefiting from nanoscale optical interactions have been truly proven to be practical in various demonstrations and have made the miniaturization of massive accelerators possible up to 10⁴ times.[5,6] among various methods, DLA accelerators have shown the highest tolerance over highly intense fields [7,8]. Also, the successful demonstration of DLAs in an integrated chip structure that could reach an acceleration of up to 1.21 keV in 30 µm with a gradient of 40.3 Mev/m, further qualifies this method.[1] However,  research in this field is bounded to the Linear accelerator (LINAC) model.[7] Here we for the first time demonstrate a novel DLA structure that accelerates in a cyclic manner thus introducing the curved structures to the field. This model is actually based on the cyclotron structure that we call the DLA cyclotron. According to square multiplication of area, this new method shifts the miniaturization of accelerators from 10⁴  reduction up to 10⁸ reduction due to cyclic acceleration in the micro-scale ring. We demonstrate an acceleration of  10 Mev in a radius of 800 µm via a gradient of 13.2 ev/m which is a record for DLA structures. This novel model is the window for nano-scale accelerators to reach the TeV range and even pass the current kilometer scale LHC ring.

Authors: Narendra Aditya , Choudhury Soumya Ranjan , Mishra Ashutosh , Misra Ipsit
Published: January 2023

The widespread usage of cars and other large, heavy vehicles necessitates the development of an effective parking infrastructure. Additionally, algorithms for detection and recognition of number plates are often used to identify automobiles all around the world where standardized plate sizes and fonts are enforced, making recognition a effortless task. As a result, both kinds of data can be combined to develop an intelligent parking system centered on ANPR technology. Extraction of the license plate characters from a photo is the primary objective of ANPR. Typically, this procedure is expensive. In this work, we introduce Chaurah, a low-cost Raspberry-Pi 3 based ANPR system designed especially for parking facilities. The system uses two stages of technique, the first of which is an ANPR system that uses two convolutional neural networks (CNNs). The first one uses a vehicle image to find and recognize license plates, while the second one uses optical character recognition to extract the licence plate numbers. The second step of the solution consists of a user-facing application made with Flutter and Firebase for database management in order to compare licence plate records. The app also functions as an interface for a payment system depending on the length of parking time, making it a full software embodiment of the concept.
Electrode Effects in mmWave Frequency Multilayer Bulk Acoustic Wave Resonators
Authors: Peng Wenhao
Published: January 2023

Electrodes are present in acoustic resonators to set electrical boundary conditions. Electrodes are acoustically part of a bulk acoustic wave (BAW) resonator that affect both its electromechanical coupling coefficient and its quality factor. Calculation of electromechanical coupling coefficient in multilayer structures requires the analysis of a system of equations relating the waves inside each layer to those in its adjacent layers. In this work, layer thicknesses and material constants in each layer are used to calculate the series and parallel resonance frequencies. Due to the proximity in frequency of series and parallel resonance, a series expansion of the series resonance frequency equation is performed around the parallel resonance frequency, and a closed form expression for electromechanical coupling coefficient from material constants and layer thicknesses is obtained to facilitate the observation of the electromechanical coupling coefficient effects of electrodes. Thermoelastic damping (TED) has been identified as the dominant acoustic loss mechanism in conductors. In this work, the complex wavenumber is calculated based on the unified theory of thermoelasticity to incorporate acoustic loss due to the interaction between elastic deformation and heat flow. Acoustic quality factors due to TED for common metals in  microelectromechanical systems (MEMS) processing are calculated to facilitate the observation of the quality factor effects of electrodes. It is observed that there exists tradeoff among electromechanical coupling coefficient, acoustic quality factor, and electrical conductivity in the selection of electrode metals.

Authors: Font Gabriel , Pons-Prats Jordi , Mora Javier , Muñoz La Rivera Felipe
Published: January 2023

The Taxibot® is a hybrid electric vehicle that can tow medium to large aircraft in the movement area of an airport. Its use can lead to lower noise levels near terminal buildings and reduce fuel consumption and emissions; Aircraft emissions and cost of the aircraft ground operations are reduced significantly. The Taxibot®, which is the name that receives the vehicle developed by IAI (Israel Aerospace Industries), has been deployed in very few airports around the world, but the number is envisioned to increase in the following years. If the system goes fully autonomous, pilots will have to learn and accustom themselves to the differences when performing the procedure with the vehicle and airports need to make studies on the effect it could have on capacity and safety. The aim of this paper is to describe the development of a simulator of the operations of a remotecontrolled tow tractor for first person training. The objective of the simulator is evaluating and improving human factors in terms of required skills and ergonomics. The study takes into account a review of the current state of the art on available tools and their shortcomings to establish requirements of the proposed solution. The steps taken to create the virtual environment, physics simulation and other systems of the implementation are disclosed. Validation of the simulated experience was conducted with users of different expertise levels. Although the validation methodology was limited in scope, most users reportedly became more aware of the processes involved in the operation of a tow car. Additionally, the experience can be updated to test new vehicles and conditions.

Optimal Decision Strategies for the Generalized Cuckoo Card Game
Authors: Mignoni Nicola , Carli Raffaele , Dotoli Mariagrazia
Published: January 2023

Cuckoo is a popular card game, which originated in France during the 15th century and then spread throughout Europe, where it is currently well-known under distinct names and with different variants. Cuckoo is an imperfect information game-of-chance, which makes the research regarding its optimal strategies determination interesting. The rules are simple: each player receives a covered card from the dealer; starting from the player at the dealer's left, each player looks at its own card and decides whether to exchange it with the player to their left, or keep it; the dealer plays at last and, if it decides to exchange card, it draws a random one from the remaining deck; the player(s) with the lowest valued card lose(s) the round.

We formulate the gameplay mathematically and provide an analysis of the optimal decision policies. Different card decks can be used for this game, e.g., the standard 52-card deck or the Italian 40-card deck. We generalize the decision model for an arbitrary number decks' cards, suites, and players. Lastly, through numerical simulations, we compare the determined optimal decision strategy against different benchmarks, showing that the strategy outperforms the random and naive policies and approaches the performance of the ideal oracle.

In this article, a nona-band metasurface with unit cell dimensions of 0.038λo×0.038λo×0.019λo is designed on a FR-4 substrate of 1.0mm thickness with 35µm copper cladding. In TE/TM mode, the absorbance is greater than 99% at the intended frequency bands (i.e., 5.76, 8.6, 12.68, 14.38, 17.05, 17.94, 19.20, 20.88, 22.62, and 23.62GHz), and its reflectivity is almost zero. Results indicated that the metasurface is found to extremely independent on the angles of polarization of the incident wave and the absorber is almost insensitive to the incident angle (0° – 90°) for TE/TM modes. The unit cell of metasurface is having negative permittivity, near zero permeability and negative refractive index at all intended bands which confirm exotic properties of the metasurface. The metasurface is having high quality-factor (Q = 72) at 5.76GHz frequency therefore, this metasurface is also useful for dielectric sensing application in intended bands.[1]The metasurface's unparalleled properties make it suitable for EMI shielding, sensing applications in the C, X, and Ku-bands, the reduction of mono-static RCS, the improvement of isolation in MIMO antennas, and the reduction of unintended noise produced by copper components used in satellite and RADAR communication.

Os reptos e raptos da Europa
Authors: Vasconcelos José Manuel de
Published: January 2023

The project of European unity has oscillated between dream and disillusion. Its future will depend on its ability to know how to think and interpret Europe’s Historical lessons, particularly since the end of the nineteenth-century, keeping in mind its remote cultural roots and the values of freedom and solidarity that survived the hecatombs it went through. Thus, increasingly seeking social justice, Europe will be able to come closer to the values that, in a broad sense, characterize its identity, not shutting upon itself, but rather opening to the world, without losing its autonomy and its inventiveness.

Saramago e os valores de Sassoli: do mítico e do ético em Caim
Authors: Neto Nefatalin Gonçalves
Published: January 2023

Cain resumes the biblical story of the genesiacs brothers to recount it in a heterodox way. Based on the canonical biblical texts, the ethical perspective of David Maria Sassoli and in ideological discourses, José Saramago (re)reads the life of the murderous brother by a desacralizing bias, establishing a process of discursive reorganization of the Bible and, consequently, of Christianity – an ideology rooted in the social thought that the writer Portuguese intends to resolve. Our proposal is to probe such ethical assumptions questioned by the novel. Thus, we will focus on the figure of the protagonist to reflect on postures, symbolic representations, narrative functions and ideological expressiveness. Let us, through our reading, decommthe kaleidoscopic clash that the skilled narrator stages to present an ethical proposal in dialogue with renewing ideals of today's society.

In David Sassoli, intelligence and cognitive awareness are placed at the service of primordial ethical values: in the passionate defence of knowledge, freedom and commitment to the common good. His deep and strong love for life expands to the way he fraternises, speaks or acts, with a relentless lucidity and moral demand. It is this attitude, this way of exercising citizenship and doing politics, that is recognisably unique and fascinating in him. An independent person who, standing outside the dominant logic and power, attracted others by his authenticity, his example, by the inner voice of a truth, which emerges.
Effect of harvest maturity stage and ripening remediation agents on the shelf life and biochemical quality attributes of tomato (Solanum lycopersicon) fruits
Authors: Oduntan Adebusola , Oyetunde Oyeboade , Shobo Bolatito , Bodunde Goke
Published: January 2023

Tomato fruit is highly perishable because of the characteristic high rate of ethylene production and respiration during ripening. Delayed ripening could be achieved through the use of ripening remediation agents (RRa) that either absorb or block ethylene binding to the fruit receptor. The effects of ripening remediation agents on shelf life and biochemical quality attributes were evaluated on tomato fruits harvested at three maturity stages (breaker, turning and full-ripe). In 2018 and 2019, harvested fruits were stored under seven ripening remediation treatments: 0.1 µL/L 1-MCP, 0.3 µL/L 1-MCP, 0.5 µL/L 1-MCP, 5% KMnO4, 10% KMnO4, 10 g of Zeolite and 20 g of Zeolite and an open shelf condition as the control. At the end of the storage period, fruits were assessed for shelf life as well as total soluble solids (TSS), titratable acids (TA), ascorbic acid, and lycopene contents. There was significant (p≤0.05/0.01) influence of ripening remediation treatments on fruits for all the measured parameters. Fruits stored with RRAs consistently out-performed those stored in the open shelf. RRAs 0.3 µL/L1-MCP, 0.5 µL/L1-MCP and 5% KMnO4 solution media had longer shelf life and higher values of total soluble solids, titratable acidity, lycopene and ascorbic acid contents. The use of 1-MCP and 5% KMnO4 is recommended as effective scavenger of ethylene for extending the shelf-life and maintaining some quality attributes of stored tomato fruits.

Published: January 2023

The lack of information on the horticultural performance of goldenberry (Physalis peruviana L.) is one of the factors that limits the expansion of the crop. Still, aiming to establish a sustainable management for this culture, inoculation with arbuscular mycorrhizal fungi (AMF) can be adopted. Therefore, the objective of the research was to investigate whether goldenberry plants in the absence and presence of inoculation with AMF differ in terms of horticultural performance. The four treatments studied were the absence (control) and the presence of three inoculants based on AMF (mycorrhizal community, Glomus intraradices and Rhizophagus clarus), arranged in a randomized block design, with five replications. Goldenberry plants produced in substrate enriched with AMF had a more voluminous root system and a greater amount of fine roots. Additionally, the fruits were sweeter and more flavorful when produced by plants inoculated with the mycorrhizal community and with R. clarus. It is concluded that mycorrhization has no effect on fruit production. However, goldenberry plants submitted to mycorrhizal biotechnology enhance the chemical quality of fruits and present a more profuse root system. G. intraradices is most effective in colonizing the roots of the plant host.
The Intervention of Mathematical Problem-Solving Model on the Systems of Linear Equation Material: Analysing its Impact on Increasing Students' Creative Thinking
Authors: Hidayat Riyan , Evendi Erpin
Published: January 2023

Students' difficulties in their experiences of the mathematics learning process are when systems of linear equations are integrated with real-world cases in everyday life. Students’ logical thinking is not strong enough to solve the problems presented. Finally, ways of creative thinking are needed as a basis for attaining learning competencies in the teaching materials of linear equation systems. On the one hand, an appropriate learning model is needed to encourage students' creative thinking. Therefore, this study aims to intervene in a mathematical problem-solving model on the linear equations system and analyze its impact on improving students' creative thinking abilities. To attain the research aims, a simple experimental method was applied with a one-group pre-post-test design. A valid essay test instrument was employed to measure students' creative thinking in the four aspects of creative thinking (fluency, flexibility, originality, and elaboration). Creative thinking data collected (pre-post-test) were then analyzed descriptively and statistically. The results of the study indicate that the model of solving mathematical problems in the materials of linear equation systems has a significant impact on improving students' creative thinking abilities. This finding becomes a reference in its application in the routine of learning mathematics, not only on linear equation systems but on other calculus materials.

Published: January 2023

The Grand Lahou lagoon system receives numerous spills from inland waters. This results in various forms of chemical pollution. Two species of fish most consumed by the Grand Lahou population are contaminated with high levels of Polychlorinated Biphenyls (PCBs). The objective of this study is to reduce the levels of PCBs in both fish species in order to provide consumers with healthy fish. The fish species most contaminated with PCBs, namely a type of catfish called ‘‘machoiron’’ (Chrysichthys sp.) and the mullet (Mugil sp.) were collected according to their weight (category 1:101-200g and category 2: 201-300g). Smoking has been proposed to reduce PCB levels. Thus two smoking techniques were used: smoking the fish traditionally using firewood as fuel and smoking on barbecue with charcoal. The level of PCB contamination in fish was determined by the gas chromatograph coupled with an electron capture detector (GC-ECD). The results obtained show that the smoking techniques used reduce the PCBi content. Wood smoking eliminates 98% of PCBs from fish compared to 88% for charcoal smoking.

This study examines the relationships between Foreign direct investment (FDI), Gross domestic product (GDP), Trade, Inflation, Labor force, Population density, Combustible renewables and waste consumption for the case of Central Asia, spanning the period 1990 to 2020. The combustible renewables and wastes consumption in Central Asia are based on the long run and short run relationship between economic development with the Error Correction Model (ECM) based Panel Cointegration tests and Panel Vector Error Correction Model (VECM) Granger causality test tried to explain using the causality test, spanning the period 1990 to 2020. An empirical analysis uses the Im, Pesaran, and Shin (CIPS) Panel Unit Root test and Westerlund ECM to test the basics of the data unit based on this information. The Panel Vector Autoregression (PVAR) specification was based on the results of the Lag-order selection criteria, and the stability of the PVAR model was checked through the observation of the Hausman test and Eigenvalue stability condition. It performs tests to verify the existence of the long run relationships among the variables and examines short and long run causal relationships. It finds that increased combustible renewables and waste consumption use is the main cause of increased economic growth.

Published: January 2023

Background: General anesthesia is very common anesthetic procedure which is used in several surgical approaches. Without general anesthesia many of these surgeries are lifesaving or life-changing and would not be possible. But all medical procedures are associated with some complications, even when they are performed by experts. The severity and rate of these complications depend on patient’s state of health, age or general lifestyle. Though the general anesthesia using is considered safe, but it comes with certain complications. Aim of the Study: The aim of this study was to assess the complications of general anesthesia in different surgeries. Methods: This was a prospective observational study. The study was conducted in the Department of Aneaesthesia, ICU & Pain Medicine, Shaheed Suharawardy Medical College and Hospital, Dhaka, Bangladesh during the period from January 2019 to December 2019. In total 57 participants in treatment under various department of the mentioned hospital and was prepared for surgery were included as the study subjects. All the demographic as well as clinical data were recorded. As per necessity all data were processed, analyzed and disseminated by using MS Excel and SPSS version 23.0 program. Results: As the complications of general anesthesia among our participants, we found somnolence, ‘dry mouth/increased thirst’ and pain in operated place were found in more than 50% cases separately which were found in 67%, 79% and 82% cases respectively. On the other hand, in 25>50% cases disorder of consciousness (25%), ‘weakness and pain of muscles (28%)’, ‘nausea and vomiting (30%)’, headache (33%) and ‘sore throat/hoarseness (37%)’ were found separately which was noticeable. Besides these, breathing problems, urination problems and feeling cold/chills were observed in some cases. Conclusion: Usually, general anesthesia is a safe way for ensuring patient’s safety and comfort during surgery, but till now it is associated with some complications which have to be recognized and deal with. Contentious development in the procedure of using general anesthesia is necessary to reduce unwanted complication.

Uterine leiomyosarcoma is a rare uterine malignancy that arises from the smooth muscle of uterine wall. Presenting symptoms may be vague and mimic other benign uterine conditions. They are notoriously aggressive with poor prognosis. We report a case of a 35-year-old female, who presented with abdominal distension with pain and vomiting. A non-tender mass measuring 14X12 cms was felt on palpation in the same region. CT scan revealed a large, relatively well defined, hypodense pelvic mass in retro-uterine pouch. Patient underwent exploratory laparotomy with primary resection of tumour with pan-hysterectomy with pelvic lymph node resection. Histopathologically, it was diagnosed as pleomorphic sarcoma probably leiomyosarcoma of uterus which showed immunostain Smooth Muscle Antigen (SMA) positive and Epithelial Membrane Antigen (EMA) negative. It was Estrogen Receptor(ER) negative. The rarity as well as pathological diversity makes this study beneficial and this definitive reporting will be helpful in diagnosis of smooth muscle tumours with challenging histologic features.

PROMETHEUS: Long-Term Exacerbation and Mortality Benefits of Implementing Single-Inhaler Triple Therapy in the US COPD Population

Published: January 2023

Background: The US population includes 24 million to 29 million people with diagnosed and undiagnosed chronic obstructive pulmonary disease (COPD). Studies have demonstrated the safety and efficacy of single-inhaler triple therapy (SITT) in reducing COPD exacerbations. Long-term population implications of SITT use have not been quantified.

Objectives: This simulation-based projection aimed to estimate the potential impact of widespread SITT use on the US COPD population.

Methods: Exacerbation and all-cause mortality reductions reported in the Efficacy and Safety of Triple Therapy in Obstructive Lung Disease trial (ETHOS; NCT02465567) were used to project clinical outcomes in US patients meeting ETHOS trial eligibility criteria (ETHOS-Eligible) and patients meeting a practical definition of SITT eligibility (Expanded ETHOS-Eligible). The US COPD population was modeled with 1000 simulations of patient progression over 10 years. Agent characteristics were based on literature and claims analysis of the 2016-2018 Medicare 100% fee-for-service and IBM MarketScan® databases. Agent annual characteristics reflected incident cases, changes in COPD severity, treatment, mortality, and exacerbations under status quo treatment patterns and scenarios for the adoption of SITT. The scenarios assumed the reduced exacerbation and mortality rates associated with SITT according to ETHOS trial outcomes mean values.

Results: Higher than current SITT adoption over 10 years would be expected to substantially reduce COPD exacerbation-associated hospitalizations by 2 million. Applying mean improvements reported in ETHOS for SITT would extend average patient life expectancy 2.2 years for ETHOS-Eligible patients and 1.7 years for Expanded ETHOS-Eligible patients. The number needed to treat to extend the average patient life by 1 year was 8 for the ETHOS-Eligible population and 10 for the Expanded ETHOS-Eligible population.

Discussion: Widespread SITT adoption may be impeded by competitive pressures from generic treatments and nonadherence, and efficacy observed in clinical trials may not occur in real-world populations.

Conclusions: Assuming ETHOS treatment effects and adherence translate to clinical practice, higher than current use of SITT can substantially reduce COPD exacerbations and hospitalizations and extend survival. These results should be viewed cautiously, because the improved outcomes for SITT in the ETHOS final retrieved vital statistics data were not statistically significant for all comparator therapy groups.
Covid-19, distanciamento controlado e dano moral coletivo: o caso das aglomerações sociais clandestinas no Rio Grande do Sul
Authors: Teixeira Neto Felipe , Rotuno Angela
Published: January 2023

Visa, o presente artigo, analisar a viabilidade da caracterização da ocorrência de dano moral coletivo com base no desrespeito das
normas de distanciamento social impostas em razão da pandemia do novo coronavírus. Tomou-se como premissa para tanto o Sistema de Distanciamento Controlado instituído no Estado do Rio Grande do Sul. Com a verificação do conceito de aglomeração e a justificativa da sua proibição, intentou-se aferir a viabilidade de, à vista da realização de festas clandestinas, configurar-se o respectivo dever de indenizar. Para tanto, partiu-se dos conceitos doutrinário e jurisprudencial do dano moral coletivo, analisando a ocorrência dos seus pressupostos na hipótese apresentada.
A reificação da pessoa privada de liberdade e a fetichização da prisão provisória
Authors: Nunes Tiago
Published: January 2023

O escopo do vertente trabalho é identificar as razões pelas quais, em geral, a prisão provisória no Brasil não é utilizada de forma técnica. Para tanto, valendo-se especialmente do arsenal teórico de Sigmund Freud e Axel Honneth, procura-se demonstrar a existência de uma correlação entre os conceitos de fetichização, reconhecimento e reificação, sobretudo a fim de esclarecer o motivo que conduz grande parte da sociedade, e em especial os integrantes do sistema de Justiça, a possuir uma visão distorcida sobre o
cárcere cautelar, inclusive utilizando-se dessa ferramenta processual como meio simbólico para satisfazer uma necessidade emocional de segurança.
“FICA EM CASA” – um elo entre múltiplas vozes
Authors: Almeida Daniel
Published: January 2023

O presente artigo é um recorte da pesquisa realizada na UAE, em Direito Civil e Administrativo Comparado, sob o título Omissão Legislativa e Covid-19: Responsabilidade Civil do Estado no Direito Português comparado ao Brasileiro. Versando sobre a Responsabilidade Civil do Estado por Omissão Legislativa, a teoria sobre Responsabilidade Civil foi aplicada ao caos pandêmico que privou os cidadãos do ir e vir social, ecoando no mundo inteiro a ordem/orientação “Fica em Casa”. Primeiro porque o contato social colocava em risco o cidadão diante da iminência do contágio pelo Coronavirus; depois porque, contaminado que ele fosse, o
sistema público de saúde não garantia atendimento, por causa do colapso de sua capacidade. A pesquisa colocou esse enunciado “Fica em Casa” no centro da análise metodológica, sob a ótica da Linguística Cognitiva, como método de análise.

Authors: Fernandes Érica
Published: January 2023

O objetivo deste artigo consiste em analisar a Recomendação Conjunta Presi-CN 02/2020, editada pelo Conselho Nacional do Ministério Público. A Recomendação demonstra algumas preocupações similares àquelas que motivaram as alterações promovidas pela Lei 13.655/2018 na Lei de Introdução às Normas do Direito Brasileiro. O artigo se propõe a analisar os dispositivos da recomendação, identificando suas semelhanças aos dispositivos inseridos na LINDB, e também trata do papel do controle da Administração Pública, em especial na fiscalização das políticas públicas. Assim, conclui-se que o principal objetivo da recomendação consiste em delimitar o espaço dos atos de gestão e dos atos de controle, o que se revela premente para garantir melhor funcionamento e eficiência da gestão pública.

Authors: Iaquinta Taciana
Published: January 2023

Este trabalho tem como objetivo apresentar um estudo sobre a relação entre Estado e Família na garantia da saúde das crianças e dos adolescentes, analisando os limites da autonomia privada em face das imposições estatais. A temática central do texto versará sobre vacinação, que merece especial atuação em razão a pandemia da Covid-19, a qual reacendeu debates nessa esfera. Para tanto, entre outros pontos, será examinada a tese fixada e o julgamento do Tema 1103 do Supremo Tribunal Federal, o qual enfrentou a problemática relacionada à obrigatoriedade de vacinação imposta pelo estado e a liberdade das convicções pessoais dos pais e responsáveis. Por fim, na conclusão, serão apontadas algumas sugestões sobre a aplicabilidade da tese e o cuidado que se deve ter com a imposição de medidas indiretas e punições para que não afetem as próprias crianças e adolescentes.
