Authors: Cancino Javiera , Lazo Sebastián , Fonseca Diego
Published: July 2023

Introducción: El hígado es el órgano encargado del metabolismo de nutrientes y algunos fármacos, así como de producir factores de coagulación. Según la Organización Mundial de la Salud, cada año se registran aproximadamente 23 millones de personas con patologías hepáticas a nivel mundial; por tanto, es habitual que el odontólogo se encuentre con estos pacientes en las consultas diarias. El objetivo de esta revisión es establecer el manejo estomatológico de los pacientes que presentan hepatopatías. Materiales y métodos: Se realizó una búsqueda de artículos indexados a las bases de datos de PubMed y EBSCO utilizando una combinación de palabras clave y los términos booleanos “oral surgery” AND “hepatitis” AND “dental management”. Resultados: Los pacientes con hepatopatías presentan importantes características para el odontólogo, las cuales deben ser reconocidas para que los procedimientos puedan ser realizados con el menor riesgo de complicaciones intra y posoperatorias. Un paciente con mal control de su patología de base se encuentra más propenso a infecciones y hemorragias, lo que implica un alto riesgo de morbilidad. Conclusiones: Se debe valorar la atención odontológica del paciente con hepatopatías según el motivo de consulta, el control de la enfermedad, la complejidad del procedimiento a realizar y las medidas hemostáticas tanto intra como posoperatorias. Se deben considerar todas las medidas hemostáticas necesarias y considerar ajuste de dosis en el uso de AINE.
Reconocimiento y manejo endodóntico de primeros premolares maxilares con dos raíces y tres conductos. Reporte de caso de bilateralidad
Authors: Molina Quispe Jairo Jhoel
Published: July 2023

La capacidad de reconocer las variaciones anatómicas del sistema de conductos radiculares es crucial antes de iniciar el tratamiento endodóntico. No menos importante es llevar a cabo estos tratamientos con base en la evidencia científica actual. Los premolares son las piezas dentales con mayor complejidad en su anatomía interna y las que se presentan en mayor porcentaje en comparación con otras piezas dentarias; si una pieza presenta anatomía accesoria, es altamente probable que la pieza contralateral presente la misma anatomía interna, a esto se le conoce como bilateralidad simétrica. Por lo tanto, las tomas radiográficas deberán ser ejecutadas con proyecciones proximales y ortorradiales para aproximarnos a la forma 3D que presentan estas anatomías y minimizar errores procedimentales. El uso de la magnificación es imprescindible para abordar todo el sistema de conductos y realizar un adecuado tratamiento endodóntico. El presente reporte de caso muestra el abordaje de los dos primeros premolares superiores maxilares de un mismo paciente con anatomía de tres conductos y simetría bilateral.

Authors: Ochoa Moreira Jorge Andrés , Reinoso Quezada Santiago José , Molina-Barahona Magdalena
Published: July 2023

El tumor queratoquístico odontogénico (TQO), también conocido actualmente como queratoquiste odontogénico (QQO), es una patología benigna derivada de los restos de la lámina dental, caracterizada por poseer cantidades variables de paraqueratina descamada y se presenta de forma solitaria o con quistes satélite. La aparición de estos quistes suele estar relacionada con la posible recurrencia del QQO y, según la literatura, esta recidiva puede variar entre el 0% y el 50%. En cuanto a la etapa de tratamiento del QQO, se puede mencionar que, en la actualidad, existe un criterio histológico y clínico bien definido, lo que facilita su reconocimiento y, por ende, su tratamiento. Existen varias modalidades de tratamiento, las cuales pueden ser clasificadas en tratamientos no conservadores o radicales, y conservadores acompañados de métodos adyuvantes. Entre los tratamientos no conservadores o radicales encontramos la resección en bloque, que es la forma más agresiva de tratar un queratoquiste; sin embargo, se ha demostrado que es la forma más eficaz para evitar la recidiva. Por su parte, entre los tratamientos conservadores se describe a la marsupialización, descompresión y enucleación, con o sin terapia adyuvante. Es importante reconocer los distintos tipos de tratamientos para el QQO, ya que este estará condicionado por múltiples factores como la localización en relación con sus estructuras óseas cercanas y el tamaño de la lesión teniendo en cuenta la posible afección de estructuras dentales. El objetivo es buscar el tratamiento de menor riesgo posible, que evite recurrencia y, finalmente, acabe con esta patología.

One of the fishery products that decomposes very rapidly is shrimp. Utilizing natural preservatives, such as Averrhoa bilimbi L. juice, is one method for maintaining the quality of food ingredients. This study aims to determine the effect of adding A. bilimbi L. juice with different concentrations and soaking times on vannamei shrimp decay. In this study, an experimental laboratory was used to examine decay using the Postma and H2S tests. As much as 500 g of vannamei shrimp were divided into four treatment groups and two repetitions, with 5 g of each sample soaked in A. bilimbi L. juice with concentrations of 0%, 2.5%, 5%, 7.5%, and 10% for 0, 3, 6, and 9 hours. Early decay was observed at 0 and 3 hours after soaking vannamei shrimp in solutions with concentrations of 0%, 2.5%, 5%, 7.5%, and 10%. At concentrations of 5%, 7.5%, and 10%, there was no initial decay after soaking vannamei shrimp for six hours at a concentration of 0% and 2.5%. During 9 hours of soaking at concentrations of 0%, 2.5%, and 5%, initial decay occurred, whereas there was no initial decay at concentrations of 7.5% and 10%. The conclusion of this research is A. bilimbi L. juice with concentrations of 7.5% and 10% for 6 and 9 hours inhibits the decomposition of vannamei shrimp.

Authors: Park Sungwon , Han Ihnsup , Oh Heekyong
Published: July 2023

Wastewater treatment plants face the challenge of controlling disinfection by-products, such as carcinogenic trihalomethanes, which are formed when disinfectants react with organic compounds and humic substances in water sources. To ensure the prevention of water pollution, effective control measures must be implemented to mitigate the release of these harmful by-products into water bodies. This study focused on the application of an electrooxidation-adsorption hybrid process for the treatment of chlorate, a prevalent disinfection by-product found in sewage plant effluent. The investigation aimed to evaluate the impact of various parameters including current density, empty bed contact time (EBCT), granular activated carbon (GAC) injection amount, electrode installation spacing, and pH on the treatment efficiency. Optimal operating conditions were determined, including a current density of 75 A/m2 , an EBCT of 5 minutes, a GAC injection amount of 2.0 w/v (%), an electrode installation spacing of 2 cm, and a pH of 2. These conditions demonstrated effective removal of disinfection by-products, even in the presence of coexisting pollutants. The findings highlight the viability of the electrooxidation-adsorption process as a promising approach for the treatment of disinfection by-products in sewage treatment plant effluent. This research contributes to the development of efficient strategies for mitigating the environmental impact of wastewater treatment processes and ensuring the protection of public water resources.
Compulsory Education Reform, Family Barriers and Female Labour Supply in Turkey: Regression Discontinuity Design with Heterogeneous Treatment Effects
Authors: Zayim Gülen Derya , Kayaoğlu Ayşegül
Published: July 2023

This study investigates heterogeneous treatment effects of compulsory education reform in Turkey on demand for education and labour supply decisions across gender groups and family status using a Regression Discontinuity Design. Although increasing the compulsory schooling years has successfully narrowed the gender gap in labour supply, we find that this effect was only through higher labor force participation of single women and women without children. In other words, our results signify that marriage and fertility have shadowed the human capital effect of higher education. Therefore, policymakers should mainly focus on supply-side policies to mitigate family barriers to raise female labour force participation in Turkey.

Resting heart rate is associated with the prevalence of chronic kidney disease in Korean adult: The Korean National Health and Nutrition Survey
Authors: Park Dong-Hyuk , Chung Choon Hee , Lee Dong Hoon , Lee Eun Young , Jeon Justin
Published: July 2023

Background
Chronic kidney disease (CKD) poses a significant health challenge, yet early detection remains difficult. Resting heart rate (RHR) has been shown to be a reliable indicator of type 2 diabetes, prompting interest in its potential as an independent predictor of CKD. This study aimed to investigate the association between RHR and CKD prevalence, as well as explore potential interactions between RHR and other risk factors for CKD in a sample of 25,246 adults.
Methods
Data from the Korean National Health and Nutrition Examination Survey (2011–2014) were utilized for this study, with 19,210 participants included after screening. Logistic regression analysis was employed to examine the relationship between RHR and CKD prevalence. Stratified analyses were conducted based on known risk factors for CKD.
Results
Participants with an RHR ≥ 90 bpm exhibited a 2.07-fold [95% confidence interval (CI): 1.30–1.73] and 2.22-fold higher prevalence of CKD in men and women, respectively, compared to those with an RHR < 60 bpm. The association between RHR and CKD prevalence was particularly pronounced in younger participants (40–59 years vs. ≥60 years), individuals with diabetes (yes vs. no), and those with a longer duration of diabetes (≥ 7 years vs. <7 years).
Conclusion
Elevated RHR was found to be significantly associated with a higher prevalence of CKD in both men and women, independent of demographic, lifestyle, and medical factors. These findings suggest that RHR could serve as a valuable predictor for undiagnosed CKD.

Authors: REJI V , Manimegalai C. T.
Published: July 2023

This research presents a frequency reconfigurable antenna analysis for wireless applications using multiple light sources. The antenna is constructed on a Roger substrate with (44x28) mm2 dimensions. The antenna comprises two parallel tuner arrangements in addition to a V-shaped radiating section. Two optical PIN photodiodes are connected to the two parallel monopole tuners, which serve as the antenna's switching component and are utilized to adjust the resonant frequency. These two PIN photodiode switches work in the 600–1050 nm wavelength range. To analyze the antenna performance, four different optical sources are used. They are White colour LED lamp, 650 nm optical fiber, red LEDs, and IR LEDs. In every cases, the antenna performance analysis are carried out for all the four logic state of the switches (00, 01,10,11). Under white lamp test conditions, the antenna's maximum gain is 6 dBi, and when red LEDs are employed as the optical source, its maximum bandwidth is 21%. The antenna reconfigurable frequencies are 3.5GHz and 5-5.8GHz (5, 5.2, 5.5, 5.8 GHz).
Minding menopause in patients with cognitive impairment: a patients' perspective and reflections on clinical practice
Authors: Thomas Elias , Verdonk Petra , Rhodius-Meester Hanneke , Muller Majon
Published: July 2023

Many women experience impairment in cognitive function during perimenopause. These symptoms are often not attributed to perimenopause by women themselves, by family and friends, and by health care professionals. In this piece, we present a case in which perimenopausal complaints were attributed to early dementia and discuss mechanisms contributing to the low level of awareness of perimenopausal amongst patients and clinicians. Stigma amongst women and health care professionals impairs the recognition of perimenopausal complaints, and consideration of treatment options by clinicians. We advocate for increased awareness amongst patients and physicians by increasing education and incorporating potential menopause-related symptoms in general clinical guidelines.

Laser Diode based THz-TDS System with 133 dB peak Signal-to-Noise Ratio
Authors: Cherniak Vladyslav , Kubiczek Tobias , Kolpatzeck Kevin , Balzer Jan C.
Published: July 2023

Terahertz time-domain spectroscopy (THz-TDS) has emerged as a powerful and versatile tool in various scientific fields. These include – among others – imaging, material characterization, and layer thickness measurements. While THz-TDS has achieved significant success in research environments, the high cost and bulky nature of most systems have hindered widespread commercialization of this technology. Two primary factors contributing to the size and cost of these systems are the laser and the optical delay unit (ODU). Consequently, our group has focused on developing THz-TDS systems based on compact monolithic mode-locked laser diodes (MLLDs). The ultra-high repetition rate (UHRR) of the MLLD has the added benefit that it allows us to utilize shorter ODUs, thereby reducing the overall cost and size of our systems. However, achieving the necessary precision in the ODU to acquire accurate terahertz time-domain signals remains a crucial aspect.To address this issue, we have developed and enhanced an interferometric extension for UHRR-THz-TDS systems. This extension is inexpensive, compact, and easy to incorporate. In this article, we present the system setup, the extension itself, and the algorithmic procedure for reconstructing the delay axis based on the interferometric reference signal. We evaluate a dataset comprising 10,000 signal traces and report a standard deviation of the measured terahertz phase at 1.6 THz as low as 3 mrad. Additionally, we demonstrate a remaining peak-to-peak jitter of only 20 fs and a record-high peak dynamic range of 133 dB after averaging. The method presented in this paper allows for simplified THz-TDS system builds, reducing bulk and cost. As a result, it further facilitates the transition of terahertz technologies from laboratory to field applications.

Published: July 2023

There is a growing interest in new semiconductor nanostructures for future high-density high-performance flexible electronic devices. Two-dimensional conjugated microporous polymers (2D-CMPs) are promising candidates because of their inherent optoelectronic properties. Here, we are reporting a novel donor-acceptor type 2D-CMP based on Pyrene and Isoindigo (PI) for a potential nano-scale charge-trapping memory application. We exfoliated the PI polymer into ~ 2.5 nm thick nanoparticles (NPs) and fabricated a Metal-Insulator-Semiconductor (MIS) device with PI-NPs embedded in the insulator. Conductive AFM (cAFM) is used to examine the confinement mechanism as well as the local charge injection process, where ultrathin high-κ alumina supplied the energy barrier for confining the charge carrier transport. We have achieved a reproducible on-and-off state and a wide memory window (ΔV) of 1.5 V at a relatively small reading voltage. Furthermore, a theoretical analysis is developed to affirm the measured charge carriers’ transport and entrapment mechanisms through and within the fabricated MIS structures. The PI-NPs act as a nanoscale floating gate in the MIS-based memory with deep trapping sites for the charged carriers. Moreover, our results demonstrate that the synthesized 2D-CMP can be promising for future low-power high-density memory applications.
Adaptive control and Modulation Techniques of Five-Level Diode-Clamped-Based Shunt Active Power Filters under Disturbed System Voltages
Authors: Mohammadtabar Kaveh , Fereidouni Alireza
Published: July 2023

This paper aims to improve the performance of five- level neutral-point-clamped-based (FL-NPC) shunt active power filters (SAPFs) that employ the direct current regulation (DCR) strategy for compensating nonlinear loads. In the DCR strategy, a main controller, which is usually a PI controller, is required to regulate the DC-bus voltage and, simultaneously, provide the reference current, while a modulation technique is used to generate the desired reference current. An adaptive PI-type fuzzy logic controller (A-PI-FLC) and an adaptive hysteresis current control (AHCC) are proposed to advance the DCR operation by providing fast DC-bus voltage regulation and modulating the reference current with a predefined constant switching frequency particularly in transient conditions, respectively. However, their superior performance may be jeopardized when voltage-type faults (sags/swells) emerge in the power system. These faults can interfere in the DC-bus voltage control and, in turn, deteriorate the modulation performance, which ultimately lead to degrada- tion of the SAPF performance. Thus, a supplementary controller (SC) is proposed and included in the control system to protect it from these faults. Extensive simulation studies are presented to validate the outstanding performance of the proposed control approaches in enhancing the performance of FL-NPC SAPFs.

In this paper, the bound state solution of the non-relativistic wave equation with a molecular potential function has been obtained in a closed-form using the Nikiforov-Uvarov method. The solutions of the bound state are then applied to study the information-theoretic measures such as the one-dimensional Shannon and Renyi entropic densities. The expectation values for \(⟨r⟩\), \(⟨{r}^{2}⟩,\) and \(⟨{p}^{2}⟩\) were obtained to verify Heisenberg’s uncertainty principle. Utilizing the energy spectrum equation, the thermodynamic vibrational partition function is obtained via the Poisson summation. Other thermodynamic function variations with absolute temperature have been obtained numerically for four diatomic molecules (H2, N2, O2, and HF). The Shannon global entropic sum inequality has also been verified. The Renyi sum for constrained index parameters satisfies the global entropic inequality. The thermodynamic properties of the four molecules are similar and conform to works reported in the existing literature. The obtained vibrational energies are in fair agreement with the ones obtained using other forms of potential energy. The result further indicates that the lowest bounds for the Shannon, Renyi, and Heisenberg inequalities are ground states phenomena.

Published: July 2023

At present, incineration and burial are the most common ways to dispose of waste cellulose which amount could reach three million tons per year, these ways not only cause serious environmental pollution but also brings a great amount of cellulose waste that could still be recycled. In this work, the chemical method is taken to study recycle of waste cellulose denim fabric, mixed sodium hydroxide and sodium hyposulfite solution were used to achieve the purpose of separating dye from waste cellulose. Only treated after 20 min, indigo separation can reach 87.33%, and the strength loss rate of waste cellulose denim fabric is only 22.24%, which could realize the recyclization of waste cellulose, and as proved, recycled indigo can be used to redye the cellulose denim fabric. The optimal conditions for indigo separation are as follows: the weight of sodium hydroxide on the fabric is 10%, the weight of sodium hydrosulfite on the fabric is 10%, the reaction temperature is 60℃, and the reaction time is 20min. According to the test results of the UV-Vis spectrophotometer, the concentration of indigo in the dye separation solution is 0.36 g/L, and the recovery rate of the dye is 75.91%. The K/S of yarn dyed with indigo separation solution can reach 1.76, which is close to the properties of yarn dyed with standard indigo.
Adaptive Handover Control Parameters Based on Cell Load Capacity in a B5G/6G Heterogeneous Network
Authors: Mohamed Maryhan , Elbadawy Hesham , Ammar Abdelhady
Published: July 2023

The handover (HO) process is one of the essential processes in mobile network management and becomes an indispensable solution for quality of service (QoS) improvement during a user's mobility. In the B5G/6G network, the deployment of small cells increased to keep up with the growth of mobile traffic. This deployment will increase the number of handovers between cells. Ping-Pong HO (PPHO) and radio link failure (RLF) are considered the two major problems in HO that may occur. So, the challenge is to set the handover control parameters (HCPs) carefully to find out the proper HO decision that should be appropriate to the environmental constraints. Therefore, in our paper, we propose an adaptive HCPs algorithm that adapts to environmental constraints such as reference signal received power (RSRP), signal to interference plus noise ratio SINR, user (UE) velocity, cell load factor, and time of stay (ToS) for the UE in the cell. In the proposed model, we have immunity to RLF, and in addition to that, we significantly minimize the amount of PPHO compared to other workers. Subsequently, we improve the HO's performance and thereby provide better throughput for serving the UE in the network than that of other workers. The proposed algorithm is implemented on different handover categories in a two-tier B5G/6G heterogeneous network. In the simulation results, our proposed model is evaluated using two frequency plans. By using frequency plan 1, the UE mean throughput increased from 270 Kbps to 281 Kbps when the serving cell was fully loaded. By using frequency plan 2, the UE mean throughput increased from 6 Mbps to 20 Mbps when the serving cell was fully loaded. In addition, the amount of ping-pong handover (PPHO) between overlapped small cells decreased and will not exceed one PPHO compared to another literature model.

Does e-commerce ease or intensify tax competition? Destination principle vs. origin principle
Authors: Aiura Hiroshi , Ogawa Hikaru
Published: July 2023

This study examines the relationship between the development of e-commerce and the intensity of commodity tax competition under two different tax principles on goods purchased online: the destination principle and the origin principle. Our main findings are as follows: Given that origin-based tax is applied to purchases made in brick-and-mortar stores, (i) tax competition under destination-based taxation on e-commerce is more intense than tax competition under origin-based taxation; (ii) tax competition under origin-based tax on e-commerce generates higher tax revenues; and (iii) the development of e-commerce raises the tax rate and tax revenues under origin-based taxation but lowers them under destination-based taxation. The main factor leading to these results is that replacing the choice of “where to purchase” goods, consumers will have a new choice of “how to purchase” when online purchasing becomes available, and the destination-based taxation distorts the latter choice, while the origin-based taxation is neutral to it. Tax competition between asymmetric regions has also been analyzed, showing that both principles result in higher tax rates and greater tax revenues for large regions than for small ones.

Ellipses and hyperbolas of decomposition of even numbers into pairs of prime numbers
Authors: Butov Gennady
Published: July 2023

This is just an attempt to associate sums or differences of prime numbers with points lying on an ellipse or hyperbola.
Certain pairs of prime numbers can be represented as radius-distances from the focuses to points lying either on the ellipse or on the hyperbola.
The ellipse equation can be written in the following form: |pk| + |pt| = 2n.
The hyperbola equation can be written in the following form: ||pk| - |pt|| = 2n.
Here pk and pt are prime numbers (p1 = 2, p2 = 3, p3 = 5, p4 = 7,...),
k and t are indices of prime numbers,
2n is a given even number,
k, t, n ∈ N.
If we construct ellipses and hyperbolas based on the above, we get the following:
1) there are only 5 non-intersecting curves (for 2n=4; 2n=6; 2n=8; 2n=10; 2n=16). The remaining ellipses have intersection points.
2) there is only 1 non-intersecting hyperbola (for 2n=2) and 1 non-intersecting vertical line. The remaining hyperbolas have intersection points.

Dentro deste contexto, o escopo deste estudo é o de mostrar uma visão genérica dos trabalhos que tratam da cultura maker, no universo de sua aplicabilidade no ensino, por meio do uso uma Revisão Sistemática da Literatura (RSL). Este artigo tem como objetivo a investigação de trabalhos que avaliam a aplicabilidade da cultura maker no ensino. Para a realização dos estudos dessa RSL, foram utilizadas bases de dados da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). A partir dos resultados encontrados, verificou-se que a temática tem grande aplicação no cenário mundial e de como sua aplicação é notória como uso de política pública para o acesso e extensão do ensino básico. Como resultado, verificou-se ainda que os estudos analisados destacam a melhoria na no nível de empregabilidade dos alunos, a redução da evasão escolar e aumento do nível de desenvolvimento de educação básica. A RSL indica, também, para a necessidade de realizar mais trabalhos relacionados à cultura maker como objeto de políticas públicas, o que propiciaria uma exploração do tema acerca da disponibilidade, bem como acesso à educação por meio do uso de tecnologias.

A demanda por uma educação permeada pela ciência, tecnologia e sociedade (CTS) tem se destacado nas produções científicas dos pesquisadores de pós-graduação no Brasil. Nesse universo,oPrograma de Pós-graduação em Ensino de Ciências e Matemática (PGECM)do Instituto Federal de Educação, Ciência e Tecnologia do Ceará (IFCE)temse destacadono tocante à formação de professores. A partir disso, notou-se, nos últimos tempos, o fortalecimentode suas pesquisasacerca da perspectiva CTSnodomínio epistemológico voltado ao ensino de Química. Sendo esse, um fator que reverberou, nos autores desta pesquisa,certas inquietações, tais como: quais os estudos produzidos sobre o ensino de Química em CTS deste programa de pós-graduação? Quais suas contribuições para a formação dos professores de Química? É possível compilar essas óticas de pesquisa consoante suas singularidades destacadas? Como a disciplina de Química em CTS está sendo evidenciada nesses trabalhos? Desse modo, compete a este estudoanalisar a produção acadêmica do PGECM acerca do ensino de Química na perspectiva CTS e sua influência para com a formação de professores entre os anos de 2015 e 2021. Para isso, efetuou-se uma Revisão Sistemática da Literatura (RSL)de abordagem qualitativa e natureza exploratória e descritiva.Em síntese, constatou-se que o quadro de formação docente nesses trabalhos situoua disciplina de Química em três classes investigativas:(i) instrumento coesivo do saber químico e das problemáticas globais envolvendo o meio ambiente, (ii) mecanismo contextualizador de situações enfrentadas pela sociedade e (iii) universo de estudos propicio para tratar das questões sociocientíficas.

A produção de tomate apresenta importante contribuição econômica e social, figurando entre os dez principais produtos agrícolas no estado de Goiás. Todavia, alguns aspectos são imperativos para obtenção do adequado resultado produtivo, dependente da adoção de sementes e mudas de qualidade. Nesse sentido, o presente estudo analisou as características observadas na relação entre viveirista e produtores baseado na abordagem teórica sobre redes de negócios/cooperação. Para tanto, realizou-se, entrevistas com donos de viveiros e análise do discurso, compreendendo, uma pesquisa de natureza qualitativa com os objetivos exploratório e descritivo. Os resultados apontam que as relações presentes entre os atores analisados não representam uma organização em rede, embora apresentem interdependência, complementaridade e laços de confiança entre as partes envolvidas; mas representam sim iniciativas que despontam como parcerias estratégicas.

Published: July 2023

A monitoria é um momento importante no processo de formação inicial docente, pois o aluno em formação tem a oportunidade de vivenciar e aperfeiçoar seus conhecimentos entre teoria e prática. Desse modo, o estudo teve como objetivo relatar a experiência na monitoria da disciplina Metodologia Científica, no curso de Licenciatura em Educação Física do Instituto Federal de Educação, Ciência e Tecnologia do Ceará, bem como discutir a importância da monitoria como instrumento de aperfeiçoamento da formação inicial docente. A monitoria se desenvolveu de 12 de Dezembro de 2019 a 12 de Dezembro de 2020. Logo, apresentou-se uma autoavaliação sobre as experiências vivenciadas, indicando que cada experiência foi importante para o aprimoramento da prática inicial do ser professor. Por outro lado, podem ser destacadas algumas dificuldades devido à pandemia da Covid-19, pois, alunos relataram que não conseguiam acompanhar a disciplina por falta de equipamentos tecnológicos e acesso à internet, o que dificultou o processo de ensino e aprendizagem.

NaI(Tl) based scintillation detectors have become a staple in the field of direct dark matter searches, with the DAMA-LIBRA experiment being the standout for its reported observation of an annually modulating WIMP-like signal which is in direct contrast with other results. In order to accurately calibrate the energies of WIMP-induced nuclear recoil signals, precise measurements of the quenching factor of the NaI crystals are essential for each of these experiments, as it is well established that electron recoils and nuclear recoils have dissimilar scintillation light yields. In this contribution, we present first preliminary results of an ongoing systematic study that has been carried out by the COSINUS collaboration and Duke University to measure the quenching factor of Na recoils. Five ultra-pure NaI crystals, manufactured by the Shanghai Institute for Ceramics, each of which have varying Tl dopant concentrations, were irradiated with a mono-energetic neutron beam at the Triangle Universities National Laboratory, North Carolina, USA to extract the quenching factor values in the low recoil energies of 1-30keV_{nr}nr.
Dark matter or millisecond pulsars? A deep learning-based analysis of the Fermi Galactic Centre Excess
Authors: List Florian , Rodd Nicholas L. , Lewis Geraint F.
Published: July 2023

The \gammaγ-ray Galactic Centre Excess (GCE) remains one of the few observed high-energy signals for which a dark matter (DM) origin is a plausible explanation. We present a deep learning-based analysis of the \gammaγ-ray sky in the Galactic Centre region, carefully accounting for the mathematical degeneracy between faint point-sources (PSs) such as millisecond pulsars (MSPs) and DM-like Poisson emission. Using recent models for the Galactic foregrounds, we find that relatively few bright PSs just below Fermi’s detection threshold seem unlikely to explain the GCE, although we continue to find evidence for PSs. Looking ahead, further improvements in the modelling of the \gammaγ-ray sky will be crucial for distinguishing between a DM-like and point-like morphology of the signal.
Approaching the first any light particle search II science run
Authors: Spector Aaron D.
Published: July 2023

The Any Light Particle Search II (ALPS II) is a light-shining-through-a-wall (LSW) experiment based at DESY in Hamburg, Germany, that will search for axions and axion-like particles down to the coupling of the axion to two photons of g_{a\gamma\gamma}gaγγ >2\times10^{-11}×10−11 GeV^{-1}−1 for masses below 0.1 meV. ALPS II will use two strings of superconducting dipole magnets that are over one hundred meters in length, as well as optical cavities before and after the wall to boost the effective signal rate of the regenerated photons by more than 12 orders of magnitude when compared to previous generations of LSW experiments. Data taking with a simplified optical system is expected to begin in early 2023.

In 2021 the Quantum Sensors for the Hidden Sector (QSHS) collaboration was founded in the UK and received funding to develop and demonstrate quantum devices with the potential to detect hidden sector particles in the \muμeV to 100 \muμeV mass window. The collaboration has been developing a range of devices. It is building a high-field, low-temperature facility at the University of Sheffield to characterise and test the devices in a haloscope geometry. This paper introduces the collaboration’s motivation, aims, and progress.
Can we really detect relic neutrinos?

Published: July 2023

Detecting relic neutrinos is a longstanding goal in fundamental physics. Experimentally, this goal is extremely challenging as the required energy resolution is defined by the tiny neutrino masses (\sim∼ 10 meV). The current consensus is that sufficient statistics together with a clean spectrum could only be achieved if beta decayers are attached to a solid state substrate. However, this inevitably imposes irreducible intrinsic limitations on the energy resolution coming from Heisenberg’s uncertainty principle. This limitation appears to be critical for the currently accepted decayer - Tritium. Here, we analyze the state of the art approaches to mitigate this limitation and conclude that the most promising solution is to change Tritium for a heavier emitter. We find that the two suitable candidates are ^{171}171Tm, ^{63}63Ni.
