Effect of Signal Coordination on the Traffic Operation of Urban Corridor
Authors: Ahmed Alkaissi Zainab
Published: January 2023

The severity of traffic congestion has increased in Baghdad city and influenced the public’s perception of the community. Extended travel time is experienced by users of the urban street system, so optimal traffic operation with a coordinated traffic signal system becomes necessary. Also, it is needed to alleviate congestion and progress traffic movement along the urban corridor. This study aims to evaluate and optimize traffic signal timing for selected intersections on Palestine arterial corridor and apply the coordinated signal system to reduce the users’ travel time on the selected urban corridor. Analyzing and evaluating congested signalized intersections using Synchro (ver.9) (Al-Nakhala intersection, Al-Sakhra intersection, and Beirut intersection) were performed. Also, their adopted strategies for improving traffic performance and reducing delays were provided. The overall assessment in terms of the level of service for the current traffic states is (LOS F) with an average control delay of (197.2, 166.8, and 262.3) sec/veh. for the Al-Nakhala, Al-Sakhra, and Beirut intersections respectively. The queue length appears after two cycles, becoming more severe congestion at intersections under oversaturated traffic conditions. The performance operation efficiency improved by reducing the control delay from (197.2 to 88) sec/veh, (166.8 to 46) sec/veh, and (262.3 to 76) sec/veh for the Al-Nakhala, Al-Sakhra, and Beirut intersections respectively. Even at high volume and oversaturated conditions, the blocked intersections were effectively alleviated. Finally, it was observed that the proposed signal coordination, built on standard actuated control significantly performed along the urban corridor, reducing vehicles’ delay. However, there are still concerns regarding the flow-to-capacity ratio (v/c ratio is still greater than 1), and the level of service is still in poor conditions (LOS E) for Beirut and (LOS F) for Al-Nakhala intersections. The application of signal coordination improved traffic progression by reducing travel time, and vehicle delay and alleviating blocked intersections.
Etnodemografía de la población de origen miskito en Costa Rica, una tarea ineludible para su reconocimiento
Authors:   Universidad Nacional (Costa Rica), Solano Acuña Ana Sofía
Published: January 2023

For more than four decades, the presence of the Miskito population in Costa Rica, the formation of their community in the capital city and the appropriation of this new territory have been made invisible by the hegemonic society and the Costa Rican State. For the elaboration of this reflection, we started from the results obtained in 2014 in the study Approach to the Miskito population in Costa Rica, which were complemented and put into perspective with a documentary review, some interviews, and a focus group. Within the framework of the Bicentennial of the independence of Central America it was considered important to recover this methodological and cultural approach, which exemplifies the complexity and variability of the population in Costa Rica. In this regard, it was concluded that recording this cultural and social diversity is the first step towards more inclusive social policies.
Cultura y migraciones: una aproximación a la percepción y valoración de la diversidad cultural en España
Authors:   Universidad de La Laguna (España), Batista Medina José Antonio
Published: January 2023

Following mainly the surveys carried out by the Centro de Investigaciones Sociológicas (2006-2017), we will analyze how Spaniards perceive the cultural diversity resulting from immigration (is it positive? To what extent?). As we shall see, the Spanish public opinion generally considers that migrants enrich culture, although with some limitations that correct the usual more positive views. This is probably due to the use of a superficial concept of culture (and, therefore, cultural diversity) that focuses on non-problematic items as music, food and the like.
Transmutaciones del zombi: del vudú haitiano a fenómeno transnacional
Authors:   Universidad de La Laguna (España), Cayuela Cánovas Marta Beatriz
Published: January 2023

Today, the figure of the zombie is widely known in most cultures. However, the image that is popularized in The Western world does not correspond to the original concept of the zombie, derived from Haitian voodoo and African religious beliefs. The aim of this work is to examine the reasons why this figure underwent a transformation when it came into contact with The West. To do this, the historical and cultural context in which it arises, the concept of the zombie in its African and Haitian roots, its popularization in The Western culture through literature and film will be investigated, until addressing the configuration of the new Western zombie archetype, which maintains only the concept of the undead- as well as its multiple interpretations and its role in transnational mass culture.

Increasing the efficiency of functioning and development of any enterprise is possible if modern management methods are used, in particular in the field of assortment management. Assortment management should be understood as the field of activity, the purpose of which is to ensure the competitiveness of the enterprise and its sustainable development by means of forming and optimizing the assortment of products. It was determined that the development of recommendations for the adoption and implementation of management decisions in the field of assortment policy of the enterprise based on optimization and modeling is an urgent issue today. In view of this, the aim of the study is to optimization of the management decision regarding the assortment policy of the enterprise using mathematical modeling under conditions of risk. Based on the results of the research, the article proposed a mathematical model and based on it, a management decision was formed regarding the optimization of the company's assortment policy, which is based on the functional relationship between the parameter of the structural level of the optimal assortment and a set of economic values (parameters, criteria), that ensure the effective commodity circulation of the enterprise in conditions of risk. The scientific novelty of the obtained results lies in the improvement of the economic-mathematical model of planning and regulation of commodity circulation of the enterprise, which is based on the assessment of the elasticity coefficient of product sales and the optimization criterion, that takes into account an expanded set of economic parameters. In this model, unlike the existing ones, two variants of the coefficient of elasticity of product sales are proposed: by price and by profit. The appropriate approach allows to reduce the possibility of risks of inaccurate and inadequate results in the context of the assortment policy of the enterprise. It is advisable to conduct further research in the direction of studying practical issues regarding the formation and use of the competitive potential of the enterprise in conditions of risk

Objective: Dexamethasone (DEX) is considered an effective treatment for Post-Embolization Syndrome (PES). However, the current commonly used DEX treatment course is long and involves a large amount of DEX and thus causes substantial side effects. This study aimed to evaluate the efficacy and safety of low-dose shortcourse DEX treatment in the prevention of PES to establish a new treatment course. Methods: A retrospective cohort study was conducted to observe the efficacy of DEX in treating PES on patients with primary liver cancer who underwent Transcatheter Arterial Chemoembolization (TACE). DEX was selected according to the wishes of the patients, who were subsequently divided into two groups. In the experimental group, 52 patients daily received an intravenous injection of 5 mg DEX and 5 mg tropisetron, starting on the day of TACE. The remaining 52 patients (control group) were treated with only 5 mg tropisetron daily. Incidence and degree of vomiting, abdominal pain, and fever were recorded. Routine blood tests and the C-Reactive Protein (CRP) test were performed, liver and kidney functions were evaluated, and the coagulation index and Eastern Cooperative Oncology Group (ECOG) performance status were assessed before and after TACE. Results: Severity scores of adverse reactions, such as vomiting, fever, and abdominal pain; incidence of grade 2 and 3 adverse reactions; and CRP and ECOG scores were significantly lower in the experimental group than in the control group (P< 0.05). There was no significant difference in routine blood parameters, liver and kidney functions, or coagulation between the two groups before or after TACE (P> 0.05). Conclusion: Low-dose and short-course DEX treatment after TACE can effectively reduce the severity of PES without side effects.

We report the influence of ionomer and catalyst dispersion solvent interaction on the structure and ionomer film wettability in copper (Cu) catalyst layers (CLs) in a gas diffusion electrode (GDE). Our results show that acetone and methanol dispersion solvents interact differently with the perfluorinated sulfonic acid (PFSA) ionomer Aquivion, which is composed of hydrophobic backbones and hydrophilic ionic heads. Acetone solvates more with the hydrophobic backbones in the PFSA compared to methanol. Consequently, the ionomer film fabricated from casting Aquivion and acetone mixture on a flat surface is more continuous and hydrophobic than its methanol counterpart. Such ionomer-solvent interaction also leads to a more uniform and flooding-tolerant GDE when producing the copper catalyst layer with acetone (acetone-CL) compared to methanol (methanol-CL). As a result, acetone-CL yields higher selectivity to C2+ products at high current density, up to 29 % greater than methanol-CL at 500 mA cm-2. Ethylene is the primary product for both CLs, reaching 47.5 4.0 % and 43.9 5.5 % at 300 mA cm-2 for acetone-CL and methanol-CL, respectively. The improvement in C2+ product selectivity for the acetone-CL is attributed to the CLs high resistance against flooding at current densities above 300 mA cm-2. Our findings offer a new strategy to advance CO2 electrolysis by manipulating solvent-ionomer interactions.

Published: January 2023

Chemo-selective and site-specific modifications of proteins are fundamental to the advancement of biological and pharmaceutical sciences, from understanding the basis of cellular biology to development of biotherapeutics. Recent successes in bioconjugation chemistry have inspired the search for more biocompatible chemical reactions, which has prompted us to investigate Horner-Wadsworth-Emmons (HWE) olefinations, iconic reactions used widely in organic synthesis that would give rise to new selective protein olefinations. Our choice of HWE olefinations was inspired by the growing number of methods for the generation of aldehydes as transient reactive groups in proteins and the potential for mild and simple reaction conditions. Here we show that HWE on aldehydes produced by both chemical and enzymatic methods is fully compatible with physiological conditions and highly selective in small and large proteins, including therapeutic antibodies. By exploiting the wide range of easily accessible HWE reagents provided by organic chemistry, we show that the reaction kinetics can be fine-tuned over orders of magnitude by judicious use of substituents. The electrophilic nature of the HWE products can be tuned to allow for subsequent nucleophilic additions, including thiol- and phospha-Michael additions, enabling two-step dual labelling strategies. Our results demonstrate that HWE olefination of aldehydes in proteins provide efficient and selective bioconjugation chemistries that are orthogonal to existing methods.
Complete active space methods for NISQ devices: The importance of canonical orbital optimization for accuracy and noise resilience

Published: January 2023

To break the scaling of the number of qubits with the size of the basis set, one can divide the molecular space into active and inactive, also known as complete active space methods. Nevertheless, more than the active space selection is needed for accuracy and effectively describing quantum mechanical effects as correlation. This study highlights the importance of optimizing the active space orbitals to describe correlation and improve the Hartree-Fock energies. We will explore orbital optimization classically and through quantum computation and how, theoretically, a chemically inspired ansatz as the UCCSD compares with a classical full CI (FCI) description of the active space in weakly and strongly correlated molecules. Finally, we will explore the practical implementation of a quantum CASSCF where hardware-efficient circuits need to be used, and noise hinders its accuracy and convergence. Moreover, we explore canonical and non-canonical active orbitals and how those influence the convergence of the quantum CASSCF routine in the presence of noise.

The NF-κB essential modulator NEMO is the core regulatory component of the inhibitor of κB kinase complex, which is a critical checkpoint in canonical NF-κB signaling downstream of innate and adaptive immune receptors. In response to various stimuli, such as TNF or IL-1β, NEMO binds to linear or M1-linked ubiquitin chains generated by LUBAC, promoting its oligomerization and subsequent activation of the associated kinases. Here we show that M1-ubiquitin chains induce phase separation of NEMO and the formation of NEMO assemblies in cells after exposure to IL-1β. Phase separation is promoted by both binding of NEMO to linear ubiquitin chains and covalent linkage of M1-ubiquitin to NEMO and is essential but not sufficient for its phase separation. Supporting the functional relevance of NEMO phase separation in signaling, a pathogenic NEMO mutant, which is impaired in both binding and linkage to linear ubiquitin chains, does not undergo phase separation and is defective in mediating IL-1β–induced NF-κB activation.

FTSJ1 is a conserved human 2′-O-methyltransferase (Nm-MTase) that modifies several tRNAs at position 32 and the wobble position 34 in the anticodon loop. Its loss of function has been linked to X-linked intellectual disability (XLID), and more recently to cancers. However, the molecular mechanisms underlying these pathologies are currently unclear. Here, we report a novelFTSJ1pathogenic variant from an X-linked intellectual disability patient. Using blood cells derived from this patient and other affected individuals carryingFTSJ1mutations, we performed an unbiased and comprehensive RiboMethSeq analysis to map the ribose methylation on all human tRNAs and identify novel targets. In addition, we performed a transcriptome analysis in these cells and found that several genes previously associated with intellectual disability and cancers were deregulated. We also found changes in the miRNA population that suggest potential cross-regulation of some miRNAs with these key mRNA targets. Finally, we show that differentiation of FTSJ1-depleted human neural progenitor cells into neurons displays long and thin spine neurites compared with control cells. These defects are also observed inDrosophilaand are associated with long-term memory deficits. Altogether, our study adds insight into FTSJ1 pathologies in humans and flies by the identification of novel FTSJ1 targets and the defect in neuron morphology.

LoRa (long range) PHY adopts simple hamming codes with maximum one-bit error correction capacity, which is one of the main causes of poor performance in fading environments. As one approach to improve performance in fading environments, in this paper, we will investigate the use of a polar code for LoRa. Specifically, through computer simulations, we will compare the performance gain in Rician fading channels according to the application of a polar code with code rate 0.5 instead of the original (8,4) hamming code in LoRa PHY.

Mixed flow ionospheric aerodynamics
Authors:   , Watson Aidan
Published: January 2023

The increasingly congested near earth environment requires accurate or-bital modelling to prevent collision events that threaten access to spaceinfrastructure. Ionospheric aerodynamics are the largest non-conservativesource of orbital perturbations. Work done by Capon et al provideda prediction method for drag forces on charged bodies in low earth orbitbased on applying approximations of single species flows to representa-tive plasma simulations. Recent work on mixed species plasma sheaths[2][3] motivates investigation of this assumption.

Mixed species plasma flows over charged bodies with representative LEOconditions were simulated, focusing on orbital motion limited O+ dom-inated flows, and sheath limited H+ dominated flows. The significanceof small concentrations of different ion species was analysed in terms ofaerodynamic effects on the body. Introduction of small concentrations ofH+ into a flow dominated by O+ molecules showed significant disrup-tions to the wake structure, coupled with an increase in drag coefficientfor a satellite in that flow. Introducing heavier O+ molecules into a sheathdominated H+ flow found little disruption to the wake structure.

A multi-species drag model was proposed, building on work in. Thismodel was found to qualitatively describe changes in wake structure, butconsistently over predicted drag coefficients. This finding suggests thatthe influence of mixed species flows on ionospheric aerodynamics involvessignificant contributions from inter-species interactions not described ad-equately by considering the separate species as either separate flows, orone flow with adjusted parameters.

Масові всихання основи лісового фонду Полісся – соснових насаджень, підтвердили, що домінуючі одноярусні одновікові монокультури не здатні протистояти викликам, спричиненим глобальними змінами клімату. Тому виникає необхідність трансформування чистих сосняків у змішані, які мають вищу біологічну стійкість. В статті оцінюються перспективи використання однієї з корінних супутніх порід сосни – дуба звичайного. Дослідження природного поновлення дуба в соснових молодняках проведено на базі лісогосподарських підприємств: ДП «Володимир-Волинське ЛМГ», «Ковельське ЛГ», «Колківське ЛГ», «Ратнівське ЛМГ», «Старовижівське ЛГ». Наводяться відомості про чисельність природного поновлення дуба в соснових молодняках. Встановлено, що змішані дубово-соснові формації куртинно-мозаїчного типу можуть спонтанно формуватися на ділянках, де сосна початково була значно зрідженою. В таких молодняках спостерігається кращий ріст і розвиток біогруп дуба природного походження. Робиться висновок про доцільність і перспективність використання природного поновлення дуба в процесі відтворення лісів, що відповідає принципам екологічно орієнтованого лісівництва.

Матеріалом дослідження було насіння моркви сорту Нантська, метаболічно активні речовини: вітамін Е (10-8 М), параоксибензойна кислота (ПОБК) (0,001%), метіонін (0,001%), убіхінон-10 (10-8 М) і MgSO4 (0,001%), та їх комбінації: вітамін Е + ПОБК + метіонін, вітамін Е + ПОБК + метіонін + MgSO4, вітамін Е + убіхінон-10. В коренеплодах моркви сорту Нантська вперше продемонстрована ефективність досліджуваних метаболічно активних речовин та їх комбінацій щодо збільшення вмісту аскорбінової кислоти та каротиноїдів, а також зниження втрат цих сполук в процесі зберігання коренеплодів. Найбільше зростання вмісту каротиноїдів спостерігалося за передпосівної обробки насіння вітаміном Е, убіхіноном-10 та комплексом вітамін Е + убіхінон-10, а найменша втрата каротиноїдів реєструвалася за застосування убіхінону-10. Найбільше зростання вмісту аскорбінової кислоти спостерігалося за передпосівної обробки насіння вітаміном Е, а найменші втрати аскорбінової кислоти реєструвалися за застосування MgSO4  та комплексу вітаміну Е + убіхінону-10. У технології вирощування моркви доцільно застосовувати агроприйоми, що передбачають передпосівну обробку насіння метаболічно активними сполуками.

A pesquisa sobre al-Qira'at al-Mutawtirah (modos autênticos de recitação) é muito limitada. Este artigo, portanto, tem como objetivo explorar a retórica de al-Qira’at al-Mutawtirah à luz das manifestações retóricas árabes. Tais manifestações incluem enunciados informativos, interrogativos e declarativos. Os pesquisadores empregaram uma abordagem analítica para analisar as instâncias selecionadas de al-Qira'at al-Mutawtirah no Alcorão, em que tais declarações foram cuidadosamente examinadas. O estudo revelou que a retórica de al-Qira'at al-Mutawtirah se manifesta em seus significados. Os significados de Qira'at podem ser aprofundados quando tentamos descobrir suas manifestações retóricas subjacentes. Além disso, os significados ocultos de Qira'at podem ser descobertos quando combinamos os significados de Qira'at. Previu-se que este estudo pudesse avançar nosso conhecimento sobre o papel dos diferentes modos de citações na compreensão dos significados do Alcorão.

La respuesta en frecuencia de sistemas lineales es una popular herramienta utilizada en el análisis y diseño de sistemas de control automático. La forma común de obtener la respuesta en frecuencia es a partir de la representación entrada-salida (función de transferencia) de un sistema. En este trabajo se presenta una manera novedosa para obtener la respuesta en frecuencia partiendo de la representación en el espacio de estados. El resultado es obtenido mediante la caracterización de la señal de entrada (función senoidal) mediante un sistema externo adicional, así como la evaluación del estado estacionario. La determinación de la fase y magnitud se obtiene de la solución a una ecuación de Sylvester reiteradamente para diferentes valores de la frecuencia en un intervalo específico junto con algunas manipulaciones algebraicas y uso de identidades trigonométricas. El procedimiento es mostrado mediante ejemplos y comparado con las maneras clásicas de obtener la respuesta en frecuencia.

The increasing demand for cosmetic products during the Covid-19 pandemic has encouraged companies to increase consumer trust and satisfaction so that consumers remain loyal to one brand, including a well-known local cosmetic product brand. This study aims to analyze the influence of brand trust and satisfaction towards consumer loyalty of a local cosmetic products brand X among generation Z. This study used a cross-sectional study design. Three hundred and eighteen respondents were collected by voluntary sampling. Data were collected through Google Forms online questionnaire and processed Structural Equation Modeling. The results showed that gender, age, education, and monthly income were positively and significantly related to brand trust. Age, monthly income, frequency of purchasing local cosmetic brand X, types of local cosmetic brand X products purchased, and duration of use of local cosmetic brand X products have a positive and significant relationship with consumer loyalty. The results of the SEM show that brand trust positively and significantly influences consumer satisfaction and loyalty. In addition, consumer satisfaction positively and significantly influences consumer loyalty. The lack of consumer confidence in the materials used by brand X in production indicates that consumer literacy regarding products still needs to improve.
The Consumer Protection on Access to Information on Sugar, Salt, and Fat

Published: January 2023

Around 70 percent of deaths in Indonesia are non-communicable diseases (NCDs) due to excessive consumption of sugar, salt, and fat. This study aims to determine consumer protection over sugar, salt, and fat information access. This research used a descriptive qualitative approach. Data were collected in March 2022 through Focus Group Discussions with informants from regulators, business associations, and consumer protection activists, as well as field observations in South Tangerang City and Semarang. The sampling method used was purposive sampling. Government regulations, business compliance, and supervision influence consumer rights to access sugar, salt, and fat information. Government regulations are still limited, and there needs to be an explanation of the implementation and standards. Many modern and traditional retailers still need to include information about sugar, salt, and fat, as well as health messages, in their product packaging. The government needs to intensify socialization and educate business actors regarding the obligation to include nutritional value information and health messages. Consumers also need to be educated about the dangers of excessive sugar, salt, and fat consumption and the nutritional literacy of their products.
