Right to the city in the age of neoliberal development: A case study of two slum communities in Dhaka, Bangladesh
Authors: Arefin Shamsul 
Published: June 2023

Due to rapid urbanization and the influence of neoliberal development policies, slum dwellers frequently encounter marginalization, inadequate living conditions, limited access to urban resources and spaces, and limited political representation throughout the world. Bangladesh is not an exception. This study investigates the right to appropriate and political participation of the urban poor in Bangladesh within the context of neoliberal development. In addition, the study critically evaluates the role of the state and various non-governmental organizations (NGOs) and civil society organizations in mobilizing the urban poor in Bangladesh. The study, therefore, implements a mixed-methods approach, including surveys, interviews, and community consultations, to obtain answers to these questions from two slums in Dhaka, Bangladesh, named Sattola and Pallabi. The findings show that the urban poor in these informal settlements confront significant challenges in claiming urban spaces due to local legislation, regulations, and development plans. As a result, they must negotiate with various formal and informal stakeholders to exercise their rights over urban spaces. The study also emphasizes that the urban poor face social and institutional barriers that limit their ability to participate effectively in decision-making, such as exclusion from formal political processes, limited access to information, and a lack of awareness of their rights. These difficulties exacerbate their marginalization from conventional urban development planning. Furthermore, the study demonstrates that due to the authoritarian state’s control over them, NGOs and other civil society organizations cannot assist the urban poor in mobilizing their right to the city. As a result, this study underlines the importance of a democratic government in Bangladesh for recognizing and defending the rights of the urban poor. Additionally, it emphasizes the importance of policy reforms and partnerships among government institutions, civil society organizations, and international actors to achieve inclusive and sustainable urban development that prioritizes the rights and well-being of the urban poor.

Published: June 2023

Abstract
The corrosion behavior of GH3535 alloys in KCl–MgCl2 eutectic salts with or without magnesium (Mg) was investigated using the static immersion tests. The effect of purification treatment on the corrosion of GH3535 specimens was also evaluated by the different analysis. The KCl–MgCl2 salts purified with Mg and reducing service temperature can slow down the corrosion rate of GH3535 specimens. Infrared spectra results showed that purification treatment reduced the content of crystal water in the KCl–MgCl2 salts. The difference of hydrate content in KCl–MgCl2 salts and the diffusion rate of Cr in alloy are the main reasons for the change of GH3535 specimens corrosion rate.

Weak solution of non-Newtonian polytropic variational inequality in fresh agricultural product supply chain problem
Authors: Wu Tao 
Published: June 2023

Abstract
In this article, we study a class of variational inequality problems with non-Newtonian polytropic parabolic operators. We introduce a mapping with an adjustable parameter to control the polytropic term, which exactly meets the conditions of Leray-Schauder fixed point theory. At the same time, we construct a penalty function to transform the variational inequality into a regular parabolic initial boundary value problem. Thus, the existence is treated with a Leray-Schauder fixed point theory as well as a suitable version of Aubin-Lions lemma. Then, the uniqueness and stability of the solution are analyzed.
Power quality enhancement of solar–wind grid connected system employing genetic-based ANFIS controller
Authors: Sowmya Sree Vemuri , Ankarao Mogili 
Published: June 2023

Abstract
The demand for electricity globally has led to the search for renewable energy resources for power generation and attaining it in an eco-friendly manner. The solar photovoltaic systems and wind-based generators of power are regarded as primary resources of renewable energy and are called Distributed Generation units as they are scattered in nature. These are operated with bidirectional converters by providing auxiliary services at grid side and load side in either mode of microgrid operation. Besides, the DC power generation units’ integration gets converted into AC system by means of inverters. These types of systems not only increase voltage and current harmonics and power frequency deviations but also drive the distribution system to risky operating zone. This emphasizes the stipulation of advanced control schemes for microgrid architecture. Consequently, power electronic converters introduce harmonics in the system and affect system performance. To report these expanded issues, the authors recognized an advanced custom power device entitled Distributed Power Flow Controller (DPFC). In this study, the proposed system on solar–wind-based hybrid energy approach has been examined primarily through the strategy of DPFC mechanism. Later, the system has been examined with Genetic Algorithm (GA)-based fuzzy logic controller and GA-based adaptive neuro fuzzy inference system controller for shunt control of context built with DPFC mechanism. Furthermore, the validated results are verified using MATLAB/Simulink software.

Abstract
Reservoirs and artificial channels are vital sources of water for irrigated areas in arid and semi-arid regions. As such, monitoring the radioecological state of these water bodies is crucial for public health and safety. In this study, we aimed to evaluate the radioecological condition of the Sobirsoy reservoir and surrounding areas. We used gamma-spectrometry to measure natural and anthropogenic radionuclides, and coal sorbents to measure radon flux density on the ground surface. Based on our findings, we conducted a radiological risk assessment and compiled an exposure dose map of the study area. The results showed that the degree of radioactive danger to people in populated areas is within safe limits. Overall, our study provides important information for policymakers and stakeholders to make informed decisions regarding the management and safety of the Sobirsoy reservoir and its surroundings.

Cohesin‐mediated DNA loop extrusion resolves sister chromatids in G2 phase

Published: June 2023

AbstractGenetic information is stored in linear DNA molecules, which are highly folded inside cells. DNA replication along the folded template path yields two sister chromatids that initially occupy the same nuclear region in an intertwined arrangement. Dividing cells must disentangle and condense the sister chromatids into separate bodies such that a microtubule‐based spindle can move them to opposite poles. While the spindle‐mediated transport of sister chromatids has been studied in detail, the chromosome‐intrinsic mechanics presegregating sister chromatids have remained elusive. Here, we show that human sister chromatids resolve extensively already during interphase, in a process dependent on the loop‐extruding activity of cohesin, but not that of condensins. Increasing cohesin's looping capability increases sister DNA resolution in interphase nuclei to an extent normally seen only during mitosis, despite the presence of abundant arm cohesion. That cohesin can resolve sister chromatids so extensively in the absence of mitosis‐specific activities indicates that DNA loop extrusion is a generic mechanism for segregating replicated genomes, shared across different Structural Maintenance of Chromosomes (SMC) protein complexes in all kingdoms of life.
Irán y Venezuela: del realismo periférico a la diplomacia resiliente (1999-2023)
Authors: Cardozo Alejandro , Niño César 
Published: June 2023

This article aims to demonstrate that Tehran and Caracas have managed to circumvent the dynamics of the international system, and have developed alternative ways of surviving the liberal order through resilient diplomacy.. Which, according to the evidence we provide, surpasses the theory of peripheral realism, not as an epistemological improvement, but as empirical facts of the foreign policy of both. Iran and Venezuela have developed two revolutionary diplomatic phases that respond to two critical moments in their relations with the Liberal International System (LIS), a rebellious phase (Chávez- Ahmadinejad) and challenges where the postulates of peripheral realism are met and later a resilient diplomacy (MaduroRaisi) that allows overcoming the LIS pressures and punishments.
Systemic approach to Smart Urban Transformations Of Cities Case of Muscat- Oman
Authors: Sallam Islam , Abdelghani Montasser 
Published: June 2023

A smart city concept ensures sustainable development and addresses urgent urban, social, economic, and environmental concerns. Smart cities have significant potential for improving the economy and living conditions of cities and their residents; however, this potential has yet to be fully realized in many countries. Given its escalating urban challenges, the current international smart-city frameworks and models are insufficient to enable developing cities, such as Muscat city of Oman, to implement the smart-city concepts successfully. Literature review and previous studies indicate a lack of studies on systematic methodologies and standards to manage, initiate, and process the urban transformation towards smart cities in developing countries. It is due to a lack of knowledge regarding the unique characteristics of methodological frameworks for smart transformation tailored to each country's social, economic, and political circumstances. This paper aims to present an integrated methodological framework for urban transformation in the context of the social, economic, and governmental factors that affect each country's approach to smart and sustainable cities. The study depended on a qualitative and critical analysis of a selective body of literature and studies. The study presents a framework that differs from previous frameworks presented in the context of developing countries as it includes: the stages of preparation, groundwork, and setting of the basis for the city, as well as the importance of these stages in building the bridges between reality and hope; KPIs at different stages allow comparison of city performance before and after based on a smart urban transformation model, a smart city planning strategy, and an Omani case study focused on the smart cities concept. Finally, the study ends by presenting a proposed model, “CLEVER”, that is assumed to be an effective approach to the smart transformation of cities in developing countries such as Muscat-Oman.

Background. microsatellite instability (MSI) is a prognostic marker of survival in many malignant diseases and show resistance to chemotherapy at early stages of colorectal cancer and show no benefits from chemotherapy at early stages of colorectal cancer. However, the role of MSI in resectable gastric cancer (GC) remains unknown.Aim. To study the results of treatment of resectable gastric cancer with microsatellite instability.Materials and methods. The study included 286 patients with resectable gC who received treatment at the N. N. Blokhin national medical Research Center of Oncology. All patients underwent PCR testing for MSI-H in 5 markers (BAT25, BAT26, NR21, NR24, NR27). Tumor regression grades (TRG) were evaluated according to the mandard tumour regression score, including disease-free survival and overall survival.Results. MSI indicated in 27 cases (9.44 %) out of 286 resectable gastric cancer. In group patients who received only surgical treatment, 2-year disease-free survival in patients with MSI-H was 77.80 % versus 88.29 % in MSS patients (hazard ratio (HR) 1.82, 95 % confidence interval (CI) 0.37–8.82, p = 0.45), 2-year overall survival in patients with MSI-H was 88.90 % versus 95.36 % in MSS patients (HR 2.03, 95 % CI 0.20–19.8, p = 0.54). In patients who received perioperative chemotherapy, 28.57 % (4 / 14) had progression in MSI-H tumor versus 3.61 % (6 / 166) in MSS tumor (p <0.001). In group patients who received treatment combined with chemotherapy, 2-year disease-free survival in patients with MSI-H was 59.60 % versus 67.36 % (HR 1.96, CI 95 % 0.88–4.35, p = 0.09), 2-year overall survival in patients with MSI-H was 67.30 % versus 85.86 % in MSS patients (HR 1.86, 95 % CI 0.64–5.41, p = 0.25)Conclusion. MSI-H is not a favorable prognosis factor in patients with resectable GC who are treated surgically combined with chemotherapy. The prevalence of progression in patients with MSI-H-status is higher than MSS-status with perioperative chemotherapy (FLOT / FOLFIRINOX).

Published: June 2023

Context is a vital concept in various fields, such as linguistics, psychology, and computer science. It refers to the background, environment, or situation in which an event, action, or idea occurs or exists. Categorization of context involves grouping contexts into different types or classes based on shared characteristics. Physical context, social context, cultural context, temporal context, and cognitive context are a few categories under which context can be divided. Each type of context plays a significant role in shaping our understanding and interpretation of events or actions. Understanding and categorizing context is essential for many applications, such as natural language processing, human-computer interaction, and communication studies, as it provides valuable information for interpretation, prediction, and decision-making.
In this paper, we will provide an overview of the concept of context and its categorization, highlighting the importance of context in various fields and applications. We will discuss each type of context and provide examples of how they are used in different fields. Finally, we will conclude by emphasizing the significance of understanding and categorizing context for interpretation, prediction, and decision-making.
