Theoretical Insights into Ultrafast Dynamics in Quantum Materials
Authors: Guan Mengxue , Chen Daqiang , Hu Shiqi , Zhao Hui , You Peiwei , Meng Sheng
Published: February 2022

The last few decades have witnessed the extraordinary advances in theoretical and experimental tools, which have enabled the manipulation and monitoring of ultrafast dynamics with high precisions. For modeling dynamical responses beyond the perturbative regime, computational methods based on time-dependent density functional theory (TDDFT) are the optimal choices. Here, we introduce TDAP (time-dependent ab initio propagation), a first-principle approach that is aimed at providing robust dynamic simulations of light-induced, highly nonlinear phenomena by real-time calculation of combined photonic, electronic, and ionic quantum mechanical effects within a TDDFT framework. We review the implementation of real-time TDDFT with numerical atomic orbital formalisms, which has enabled high-accuracy, large-scale simulations with moderate computational cost. The newly added features, i.e., the time-dependent electric field gauges and controllable ionic motion make the method especially suitable for investigating ultrafast electron-nuclear dynamics in complex periodic and semiperiodic systems. An overview of the capabilities of this first-principle method is provided by showcasing several representative applications including high-harmonic generation, tunable phase transitions, and new emergent states of matter. The method demonstrates a great potential in obtaining a predictive and comprehensive understanding of quantum dynamics and interactions in a wide range of materials at the atomic and attosecond space-time scale.

Published: February 2022

In this paper, a parallel quadrupedal robot was designed that is capable of versatile dynamic locomotion and perception-less terrain adaptation. Firstly, a quadrupedal robot with a symmetric legs and a powerful actuator was implemented for highly dynamic movement. Then, a fast and reliable method based on generalized least square was proposed for estimating the terrain parameters by fusing the body, leg, and contact information. On the basis of virtual model control (VMC) with the quadratic program (QP) method, the optimal foot force for terrain adaptation was achieved. Finally, the results obtained by simulation and indoor and outdoor experiments demonstrate that the robot can achieve a robust and versatile dynamic locomotion on uneven terrain, and the rejection of disturbances is reliable, which proves the effectiveness and robustness of this proposed method.

Perfil acadêmico e produtividade científica dos docentes de Bio(ética) no ensino da fonoaudiologia do Rio Grande do Sul
Authors: Pereira de Souza Tiago , Gomes Erissandra
Published: February 2022

Resumo: A necessidade da aplicação dos conhecimentos em ética e bioética, na prática em saúde é cada vez mais emergente, dadas às transformações socioculturais que expõem o trabalhador a problemas éticos de complexidades imensuráveis. Na contramão desta demanda, as formações em saúde precarizam na quantidade e na qualidade do ensino destas temáticas. No sentido de contribuir com a problematização do ensino, esta pesquisa propôs estabelecer o perfil acadêmico e a produtividade científica dos docentes que ministram disciplinas de Ética e Bioética nas graduações de Fonoaudiologia no Rio Grande do Sul (RS), discutindo a inserção desses profissionais nas áreas ministradas. Para isso, se configurou em uma análise documental, descritiva exploratória e de caráter quali-quantitativo, usando como base de dados o conjunto de currículos disponíveis na Plataforma Lattes do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). O estudo aponta, entre outros achados, que apenas quatro docentes são Fonoaudiólogos, demonstrou um importante distanciamento entre a atuação dos docentes e suas produções acadêmicas e científicas, com as áreas que ministram, além de evidenciar que a maioria dos docentes não possui em seus currículos nenhum indicador relacionado a ética e bioética. Propõe uma discussão a partir dos temas publicados nos artigos científicos: formação em Medicina; comunicação entre Médico e paciente; ensino da ética para a Medicina; confiança, autonomia e bioética. Percebe-se a urgência do debate sobre a formação, visando ampliar essa discussão, visto que, fica mais do que claro, que o ensino da ética e da bioética na Fonoaudiologia carece de atenção.

Antroponímia literária: uma análise dos nomes dos personagens da obra senhora, de José de Alencar
Authors: Pedrassani Júlia Sonaglio , Eckert Kleber , Röhrig Maiquel , Gebing Samuel
Published: February 2022

Resumo: Este trabalho apresenta uma análise dos nomes dos principais personagens do romance urbano Senhora, de José de Alencar, publicado em 1875. Esta pesquisa é amparada pela Antroponímia, área da Onomástica dedicada ao estudo de nomes de pessoas, bem como pela Antroponímia Literária, que é exclusiva dos nomes de personagens literários. O objetivo deste estudo foi verificar se o autor do romance escolheu os nomes dos personagens de Senhora fortuitamente ou se foi feita uma pesquisa acerca do seu significado e/ou etimologia. Abrangem-se conceitos dessa corrente teórica de suas ramificações, bem como apresenta-se, brevemente, o enredo da obra e uma contextualização acerca do período literário em que o romance está inserido, o Romantismo. Após a revisão de literatura acerca dos conceitos teóricos que embasam esse estudo e a leitura atenta do livro, foi feita a análise dos nomes e sobrenomes dos personagens comparando suas características com o significado e/ou etimologia dos seus nomes encontrados em dicionários de nomes próprios, como Andrade (1994), Guérios (1973), Martins (2002), Obata (1986) e Oliver (2005). Os resultados do estudo mostram que José de Alencar, ao escrever Senhora, não escolheu os nomes dos personagens fortuitamente, mas sim com base no seu significado e/ou etimologia dos nomes, o que enfatiza as características mais fortes de cada personagem.

Published: February 2022

Resumo: O presente estudo teve como objetivo analisar as concepções e percepções dos Técnicos Administrativos em Educação quanto à inclusão de estudantes com Necessidades Educacionais Específicas na Educação Profissional e Tecnológica. A pesquisa se insere numa abordagem qualitativa. Os dados foram coletados por meio de questionário semiestruturado, aplicado com os 24 técnicos administrativos que compõem o quadro efetivo de um campus do Instituto Federal de Alagoas, por meio da plataforma online Google Forms. Com base na análise dos resultados, depreende-se que os técnicos administrativos são atores sociais relevantes à disseminação dos valores construídos no ambiente escolar, de tal modo que suas práticas podem somar-se às dos demais profissionais, visando à consolidação de um projeto educacional inclusivo, que transcende a sala de aula e a relação professor-aluno, para acontecer em todos os espaços e na interação com todos os que compõem as instâncias administrativas e pedagógicas da instituição. Concluiu-se, entretanto, que existe uma demanda de formação em educação inclusiva para esses profissionais, tendo em vista a superação do modelo educacional que secundariza e invisibiliza a participação dos técnicos na construção de práticas educativas inclusivas.

Authors: Meneguetti de Moura Graziele , Viviane Raffa Rodrigues Renata , Casari Angelico Danubio
Published: February 2022

Resumo: Desde o início do curso, por meio do Programa Institucional de Bolsa de Iniciação à Docência (PIBID), o licenciando tem sido incentivado a participar de ações ligadas ao fazer docente na escola. Inserido no contexto específico do Subprojeto Matemática do PIBID, este estudo tem por objetivo explicitar elementos da subjetividade presentes nas percepções dos pibidianos sobre os acontecimentos relativos às experiências de Iniciação à Docência de acordo com a singularidade dos sentidos atribuídos a elas. Assente na metodologia da pesquisa qualitativa, esta investigação envolve a análise interpretativa de um material escrito que reúne narrativas individuais de 20 bolsistas do programa. Os resultados evidenciam que os acontecimentos que marcaram e se constituíram experiências para pibidianos nas atividades desenvolvidas na escola referem-se: a) ao primeiro contato com os alunos; b) à compreensão do papel do professor; e c) à ressignificação da escolha profissional. Ter sido afetado por tais acontecimentos, impeliu a abertura dos pibidianos aos processos de perceber de maneira própria e contextual os seguintes aspectos relevantes que envolvem a Iniciação à Docência: a) lidar com os sentimentos de insegurança, medo e despreparo; b) elaborar estratégias de ensino a partir do conhecimento dos alunos, das suas dificuldades e formas de pensar; e c) refletir sobre as implicações das ações docentes na vida dos alunos. Assim, a narrativa escrita se manifestou como fonte de ressignificação das experiências na escola e de apoio ao processo de transição da visão de aluno à de professor na formação inicial.

Fully roll-to-roll gravure printed electronics: challenges and the way to integrating logic gates
Authors: A. M. Tiara , Moon Hyeokgyun , Cho Gyoujin , Lee Jinkee
Published: February 2022

Printed electronics have been considered to bring about the ICT (Information Communication Technology) revolution. The high-throughput production of the ultra-low-cost printed devices along with the level of integration of logic gates via an all roll-to-roll (R2R) printing method has been the major axes in the revolution. However, there have been certain concerns related to the integration of logic gates via the R2R printing methods. This review paper focuses on the key issues that must be resolved to maintain a uniform threshold voltage (V
th) value, which can otherwise impede the commercial viability of such devices. Amongst the various factors contributing to the ΔV
th value, the ink rheology, web handling, and the disparity in alignment amongst the drain-source electrodes and the gate electrodes due to the limitations of an overlay printing registration accuracy (OPRA) were reviewed to effectively control the variations during the R2R printing process, without including the material’s intrinsic instability factors. Accordingly, a unique design rule for the R2R printing foundry concept was introduced for manufacturing the devices with the available integration level of the logic gates, incorporating the printing parameters including ink rheology, ink transfer, web handling, and OPRA.
Atomic diffusion bonding in air using Ag films
Authors: Watabe Yuki , Goto Fuki , Uomoto Miyuki , Shimatsu Takehito
Published: February 2022

Atomic diffusion bonding (ADB) of wafers at room temperature in air was studied using Ag films. Using an ultra-high vacuum magnetron sputtering system, Ag (20 nm) films with Ti (5 nm) underlayers were deposited. The propagation speed of crystal lattice rearrangement in the bonding process decreased with an increased exposure time of film surfaces to air (t
exp). Propagation did not occur at t
exp of 500 s. The cohesion of Ag film surfaces by film surface exposure to air and reduction of the Ag film surface energy by Ag oxide or sulfide formation probably cause ADB performance degradation.

This study aims to analyze the role of the Indonesian government in handling Covid19 in the health and economy of the Indonesian people under the new normal. The research method used is descriptive qualitative and quantitative methods, using research results, references and online news sources that are directly related to this research. The Covid-19 pandemic has affected the world, and Indonesia is one of them. Indonesia is fighting Covid-19 by modifying its regional isolation (lockdown) policy into large-scale social restrictions (PSBB), which are applied locally based on the severity of the province, district, or city. In addition, along with the increasing number of cases of the new variant of the COVID-19 virus from July 26 to August 2, 2021, the Indonesian government has begun to continue its policies to eradicate the corona virus and implement restrictions on community activities (PPKM). PPKM is extended for each blood differently. For regions, especially Lampung, it was extended from 10 to 23 August 2021. The COVID-19 pandemic requires the government to formulate extraordinary policies. Addressing health problems, protecting the public through social security and protecting business policies are the top priorities. Budget reallocation, reorientation of activities and adjustment of mandatory spending are the main ways the government provides funds to respond to the needs of COVID-19. On the other hand, pseudo growth also refers to the challenges that the economy may face in the second half of 2021, due to the implementation of emergency PPKM and level 4 caused by the Delta variant.

Background: HIV patients are more likely to develop cardiovascular disease than the general population and have a 2500-fold increased risk of developing pulmonary artery hypertension (PAH). HIV associated pulmonary hypertension was said to be more severe and is associated with higher mortality. Methodology: Across-sectional conducted among consecutive HIV patients age greater than 18 years receiving treatment at the antiretroviral therapy (ART) clinic of the Federal Medical Centre Nguru Yobe State Northeastern Nigeria. Results: One hundred and twenty (120) subjects were recruited into the study, thirteen had incomplete data and were excluded from the analysis. There was a significant negative correlation between CD4 cells count with tricuspid regurgitant flow velocity (TRv), pulmonary regurgitant flow velocity (PRv), pulmonary artery trunk diameter (PATd), right ventricular to left ventricular internal diameter (RV/LV) ratio, left ventricular eccentricity index (LVEI), and right atrial area (RAA), while the correlation between CD4 cells count and right ventricular acceleration time (RVAT) was positive and significant. On the other hand, the correlations between viral load and TRv, PRv, PATd, RV/LV ratio, and RAA were positive and significant while that between viral load and RVAT was negative and significant. Conclusions: This study revealed that HIV patients with low CD4 cell count and high viral load had a high probability of developing PAH ( significant negative relationship between variables associated with the probability of PAH with CD4 cell count and significant positive relationship with viral load), In HIV patients the probability of developing PAH decreases with adequate treatment (that suppress viral replication and increases CD4 count). We, therefore, recommend routine assessment of the probability of PAH in patients with HIV infection particularly those with low CD4 cell count and high viral load and encourage early commencement of HAART to prevent the development of pulmonary arterial hypertension.

Published: February 2022

Background: Autosomal dominant polycystic kidney disease (ADPKD) also known as Adult Polycystic Kidney Disease (APKD) is one of the most common systemic hereditary diseases. The disease usually presents between 20 to 39 years of age, although milder forms may not present until over 60 years and absence of renal failure has been rarely observed in some patients up to 80 years of age. Three distinct gene defects have been implicated in the pathogenesis of APKD designated as PKD1, PKD2, and PKD3. Patients with APKD may be asymptomatic, or may usually present with hypertension (in 50-70% of cases), renal insufficiency, and the complications of multiple cysts (haematuria, pain and infection) or as an abdominal mass discovered on incidental clinical or imaging examination. APKD is said to be rare in Africans. Case report: We report a case of an incidental finding of autosomal dominant polycystic kidney disease (ADPKD) in a 52-year-old normotensive man with a normal renal function test. Haematuria, dysuria and low-grade fever were the presenting complaints. The role of radiology in the diagnosis and management of ADPKD was highlighted. Conclusion: Although APKD is rare in Africans, a high index of suspicion for the disease is essential for the diagnosis of the disease especially in elderly patients with a family history of APKD who present with haematuria associated with multiple renal cysts.

developed secondary bacterial or fungal infection in 8%. Mucormycosis infection of the sinuses is a form of life-threatening invasive fungal
sinusitis that typically affects immunocompromised individuals with an impaired neutrophilic response.
Aims: 1) To study the histopathological features in cases labelled as invasive fungal sinusitis. 2) To study the association of age, gender, positive
history of Covid-19 infection, co-morbidities, use of corticosteroids and clinical presentation of cases of mucormycosis. 3) To compare our
observations with the study of other authors.
Materials And Methods: A cross – sectional observational study was undertaken at Chhattisgarh Institute of Medical Sciences, Bilaspur,
Chhattisgarh in Department of Pathology, over a period of 6 months from May to October 2021. Biopsies received were then processed as per the
standard operating procedure and stained with H & E staining and observed under microscope.
Results: On histopathological examination, we observed that the lesional tissue in the nasal biopsy/ maxillary sinus biopsy was lined by respiratory
epithelium and showed numerous broad, non – sepatate hyphae, at places showing branching. Few of the cases showed focal spore formation.
Conclusions: This study was useful in understanding histopathological features of this not–so–common fungal infection. This study also subtly
pointed towards the demerits of inadvertent use of corticosteroids in treatment of Covid-19 patients, especially in those with co-morbidities like
diabetes mellitus and elderly patients. The need of the hour, therefore, is to have “customized” treatment for every patient
A RARE PRESENTATION OF BILATERAL PAPILLEDEMA WITHOUT HYDROCEPHALUS: A CASE REPORT
Authors: Qadir Abdul , Karan Siddharth
Published: February 2022

Generally intracranial tumors causing bilateral papilledema present with hydrocephalus. The lack of hydrocephalus despite extensive and
aggressive tumor spread make this case unique to report. We report a case of 11-year-old girl who presented with left sided headache with visual
deterioration and bilateral fundoscopy on fundus examination. Magnetic resonance imaging (MRI) revealed an extra axial intracranial mass in the
middle cranial fossa compressing the ventricles and the orbit. Even though there was ventricular compression and midline shift, the patient had
bilateral papilledema without hydrocephalus. It is thought that the papilledema developed by some other mechanism and is not connected with
hydrocephalus. Raised intracranial pressure in children can be due to Idiopathic intracranial hypertension (pseudotumor cerebri) or due to a
secondary cause like meningitis, structural defects, tumors as seen in this case. Therefore, fundus examination is important in pediatric patients
presenting with headache as papilledema may be the rst sign of an intracranial tumor with or without hydrocephalus.

Published: February 2022

Background and Purpose: Lumbar spondylolisthesis is a relatively common condition that is recognized as a potential cause of low back and
1 2
lower extremity pain. Wiltse and Newman originally classied spondylolisthesis into ve groups that are dysplastic, isthmic, traumatic,
pathologic, and degenerative causes. Surgical fusion of lumbar spondylolisthesis is an important method to stabilize spine, and is used to reduce
3
pain and decrease disability in patients with chronic low back Pain . Procedures that have been widely used in the treatment of spondylolisthesis
4-5 include anterior lumbar interbody fusion, posterolateral fusion (PLF), posterior lumbar interbody fusion (PLIF), and circumferential fusion . PLF
is often combined simultaneously with PLIF through solo posterior approach, aiming to further increase fusion rate.
Results: In the present study 34 cases with spondylolisthesis were taken and were randomly enrolled into two groups. 16 patients who underwent
posterolateral fusion(PLF) were kept in Group I and rest of the 18 patients, those who underwent posterior lumbar with interbody fusion
(PLIF+PLF), were kept in Group II. Two groups were compare on the basis of clinical outcomes as postoperative reduction in back pain and
radicular pain assessed as improvement in visual analog score and postoperative functional improvement as improvement in oswestry disability
index. Pain and functional status were improved signicantly in, PLF and PLIF+PLF Group and there was no difference in both group. Slip angle
and slip percentage were signicantly improved in, PLF and PLIF+PLF Group and there was no difference in both group. However, Fusion rate
was better in PLIF+PLF group compared to PLF group. Hardware malfunction were more in PLF group, while bleeding was more common in
PLIF+PLF group.
CORRELATION BETWEEN NASAL MUCOCILIARY CLEARANCE AND PEAK EXPIRATORY FLOW RATE IN YOUNG HEALTHY ADULTS
Authors: Sood Trishla , Yadav Jyoti
Published: February 2022

Background: There are fewer studies on correlation between NMC and PEFR in young healthy adults in Indian population, of age group 18-24
years.
Objective:To correlate nasal mucociliary clearance and peak expiratory ow rate in young healthy adults, including both females and males.
Method: In a cross-sectional study, NMC was assessed by Anderson's Saccharin method and PEFR was measured with standard Wright's peak
ow meter in sixty young healthy adults of age 18-24 years. In the selection process of subjects, strict criteria of "normality" were applied and
included history of medical illnesses, general examination and systemic examination. Diseases affecting NMC and PEFR were excluded. The
correlation of NMC and PEFR was done by Pearson's equation.
Results: The correlation between mean NMC and PEFR of young healthy adults (n=60) including both females and males, revealed a weak
positive correlation (r = 0.1), which was insignicant (p 0.449).
Conclusion: In young healthy adults, as the NMC increases, the PEFR also increases but the relationship between the two is not very strong.
However, there is not much reported study on correlation of NMC and PEFR. Hence, it needs to be elucidated by further studies.
ASSESSMENT OF THE AUTONOMIC AND PERIPHERAL NERVE FUNCTION IN PATIENTS WITH THALASSAEMIC SYNDROME IN A TERTIARY CARE HOSPITAL - A CROSS SECTIONAL STUDY
Authors: Sahai Shivesh , Mukhopadhyay Mainak , Kar Auriom , Banerjee Sukanya
Published: February 2022

INTRODUCTION: β-thalassaemia is an inherited disorder of haemoglobin characterized by an absence or reduced synthesis of the β-globin
chain. The net result is an excess of α-chains, which precipitate and destroy the red cell precursors, leading to anaemia, skeletal changes,
splenomegaly and numerous other complications. Treatment is by regular blood transfusion coupled with iron chelation therapy to prevent iron
accumulation and organ damage.
AIM: To assess the autonomic and peripheral nerve function in patients with thalassaemic syndrome.
MATERIALAND METHODS: Patients attending the Thalassaemia Clinic of Medical College Hospital, Kolkata. Indoor patients from Medicine
st th ward and Institute of Haematology and Transfusion Medicine wards of Medical College Hospital, Kolkata from 1 May 2008 to 30 April 2009.
After inclusion patients were divided into following groups: Group1 (THAL1): Patients requiring regular blood transfusion and are either
receiving inadequate iron chelation or no iron chelation at all. Group2 (THAL2): Patients who require regular blood transfusion and are receiving
adequate iron chelation. Group3 (THAL3): Patients who do not require regular blood transfusion
RESULT: The median value of distal latency of right common peroneal nerve is slightly increased in all 3 groups. The normal value should be <
4.55ms, thus increase in distal latency is seen in all 3 groups. The median values of distal latency of left common peroneal nerve as well as distal
latency of common peroneal nerve as a whole is within normal limits. Distal latency of common peroneal nerve (p value=0.012). Proximal latency
of left common peroneal nerve(p value=0.013). Proximal latency of common peroneal (p value=0.001)
CONCLUSION: There is demyelinating type of neuropathy of right common peroneal nerve of all the groups. This indicates presence of motor
peripheral neuropathy in patients of thalassaemia. All other latencies and amplitudes of both motor and sensory nerves are within normal limits.
There were statistically increased motor latencies in patients receiving iron chelation therapy with adequate chelation when compared to the other
groups, although the overall latency was within acceptable limits of the laboratory standards. This may be due to subclinical affection of the motor
nerves in the form of demyelination. Therefore, the role of toxic effects of iron chelator on peripheral nerves needs to be studied further.
An Equivalent Surface Dipoles based Electric Field to Magnetic Field Transformations for Estimating Radiated Emissions
Authors: binda pankaj , Mitharwal Rajendra , Singh Ghanshyam
Published: February 2022

The new generation of communication devices operating in higher frequency bands is constantly pushing the complexity of field measurements for electromagnetic compliance and the design of field probes. These compliance are to be met for both electric and magnetic fields, of which if one set is available, the other can be estimated computationally using source reconstruction algorithms. The main objective of this paper is to refine the dipole-based source reconstruction algorithms using surface equivalence principle. Compared to earlier works, the algorithm is based on a novel way of placing a single dipole per point tangentially to a fictitious surface based on surface equivalence theorem instead of multiple orthogonal dipoles per point. We also rigorously prove the existence, uniqueness, and error bounds involved in the inverse problem. The numerical results are compared with the state-of-art to demonstrate the effectiveness in obtaining accurate fields and locating the regions of the Device Under Test responsible for overshooting the interference limits.
Resource Allocation for Joint Interference Management and Security Enhancement in Cellular-Connected Internet-of-Drones Networks
Authors: HASSAN MD ZOHEB , Kaddoum Georges , Akhrif Ouassima
Published: February 2022

Internet-of-drones (IoD) systems require enhanced data transmission security and efficient interference management to accommodate the rapidly growing drone-based rate-intensive applications. This paper develops a novel resource allocation scheme to jointly manage interference and enhance the physical layer security of cellular-connected IoD networks in the presence of a multi-band eavesdropping drone. Our envisioned cellular-connected IoD network has multiple full-duplex cellular base stations (CBSs), where each CBS reserves an orthogonal cellular radio resource block (RRB) for the aerial communication links. To efficiently utilize the cellular RRBs, each CBS is connected to a cluster of data transmitting drones using uplink non-orthogonal multiple access (NOMA) scheme. In addition, all the CBSs simultaneously transmit artificial noise signals to weaken the eavesdropper links. A joint optimization problem, considering the transmit power allocation and clustering of the legitimate drones, and the jamming power allocation of the CBSs, is formulated to maximize the worst-case average sum-secrecy-rate of the network. To obtain an efficient solution, the joint optimization problem is decomposed into drone-clustering and power allocation sub-problems. A multi-agent reinforcement-learning framework is devised to solve the drone-clustering sub-problem. Meanwhile, the transmit and jamming power allocation sub-problem is solved by employing fractional programming, successive convex approximation, and alternating optimization techniques. By iteratively solving these two sub-problems, a convergent and online resource allocation algorithm, namely, security and interference management with reinforcement-learning and NOMA (SIREN), is proposed. The superiority of SIREN over several benchmark schemes is verified via extensive simulations.
