Simultaneous phase and amplitude modulation for dual-sensitivity profilometry of discontinuous objects
Authors: Servin Manuel , Paez Gonzalo , Padilla Moises , Garnica Guillermo
Published: September 2022

Fringe projection profilometry (FPP) is a well-known technique for digitizing solids. In FPP, straight fringes are projected over a digitizing solid, and a digital camera grabs the projected fringes. The sensitivity of FPP depends on the spatial frequency of the projected fringes. The projected fringes as seen by the camera are phase modulated by the surface of the digitizing object; the demodulated phase is usually wrapped. If the digitizing object has discontinuities larger than the fringe period, the phase jumps are lost. To preserve large phase discontinuities, one must use very low spatial frequency (low-sensitivity) fringes. The drawback of low-sensitivity FPP is that the demodulated phase has low signal-to-noise ratio (SNR). Much higher SNR is obtained by projecting shorter wavelength, at the cost of obtaining wrapped phase. A way out of this problem is to use dual-wavelength FPP (DW-FPP). In DW-FPP, two sets of projected fringes are used, one with long wavelength and another with shorter wavelength. Due to harmonics and gamma distortion, in DW-FPP, one usually needs four phase-shifted fringes for each sensitivity. Here we are proposing to combine the two sensitivities simultaneously, one coded in phase (PM) and the other coded in amplitude (AM), in order to obtain phase and amplitude modulated (DW-PAM) fringes. The low-sensitivity phase is coded as AM of the DW-PAM fringes. The main advantage of DW-PAM fringes is that one reduces the number of phase-shifted fringes by half: instead of using eight phase-shifted fringes (four for low and four for high sensitivities), one would need only four DW-PAM fringes. Of course, if one wants to increase the harmonic rejection of the recovered phase, one may use a higher order phase-shifting algorithm (PSA).
Design and evaluation of an MRI-ready, self-propelled needle for prostate interventions
Authors: Bloemberg Jette , Trauzettel Fabian , Coolen Bram , Dodou Dimitra , Breedveld Paul
Published: September 2022

Prostate cancer diagnosis and focal laser ablation treatment both require the insertion of a needle for biopsy and optical fibre positioning. Needle insertion in soft tissues may cause tissue motion and deformation, which can, in turn, result in tissue damage and needle positioning errors. In this study, we present a prototype system making use of a wasp-inspired (bioinspired) self-propelled needle, which is able to move forward with zero external push force, thereby avoiding large tissue motion and deformation. Additionally, the actuation system solely consists of 3D printed parts and is therefore safe to use inside a magnetic resonance imaging (MRI) system. The needle consists of six parallel 0.25-mm diameter Nitinol rods driven by the actuation system. In the prototype, the self-propelled motion is achieved by advancing one needle segment while retracting the others. The advancing needle segment has to overcome a cutting and friction force while the retracting needle segments experience a friction force in the opposite direction. The needle self-propels through the tissue when the friction force of the five retracting needle segments overcomes the sum of the friction and cutting forces of the advancing needle segment. We tested the performance of the prototype in ex vivo human prostate tissue inside a preclinical MRI system in terms of the slip ratio of the needle with respect to the prostate tissue. The results showed that the needle was visible in MR images and that the needle was able to self-propel through the tissue with a slip ratio in the range of 0.78–0.95. The prototype is a step toward self-propelled needles for MRI-guided transperineal laser ablation as a method to treat prostate cancer.

Das sete espécies de tartarugas marinhas, cinco ocorrem no Brasil, sendo Chelonia mydas a mais frequente na região sul. Assim como outros animais marinhos, C. mydas tem um histórico de interação com resíduos de origem antrópica. Desta forma, este estudo tem como objetivo avaliar a incidência de resíduos sólidos no trato gastrointestinal de espécimes coletados sistematicamente pelo Projeto de Monitoramento de Praia da Bacia de Santos (PMP-BS) no litoral centro-norte de Santa Catarina, entre Março de 2016 e Março de 2019. Foram realizadas necropsias em 3174 animais, e em 49 indivíduos o trato gastrointestinal pôde ser recolhido triados. Foram encontrados resíduos antrópicos, separados e classificados de acordo com a sua composição, rigidez e cor. Foi avaliado o possível efeito dos resíduos antrópicos na saúde das tartarugas, utilizando o escore corporal. Também foram analisadas a ocorrência de exemplares entre as estações do ano, ingestão de resíduos por sexo e classe etária. Dos 49 indivíduos com análise detalhada, 85,7% possuíam algum tipo de resíduo, sendo encontrados um total de 475 fragmentos de 10 itens, onde os fios de poliamida foram os mais frequentes (n=275 fragmentos; 57,9%), seguido de plástico (n=170; 35,8%). A maioria dos itens ingeridos (96,2%) foi representado por materiais maleáveis, apenas 3,8% composto por material rígido. Os fragmentos transparentes foram os mais frequentes (28%), seguido das cores azul (24,4%), branco (18,7%) e verde (12,4%). Foram identificadas 37 fêmeas, nove machos e três de sexo indeterminado, onde 45 indivíduos foram considerados juvenis e quatro adultos. As tartarugas adultas ingeriram somente itens do tipo maleável, principalmente nas cores transparente (29,4%) e verde (32,4%). Já os juvenis apresentaram mais itens maleáveis transparente (27,9%), azul (25,2%) e branco (20,0%), além de itens do tipo rígido.
A participatory approach to embedding evidence in practice to support early language and communication in a London nursery school

Published: September 2022

IOE (Institute of Education), UCL’s Faculty of Education and Society (University College London, UK) has a long tradition of engagement with schools to support young children’s learning and co-produce knowledge through research–practice partnerships. From the first demonstration schools in the early 1900s to engagement with contemporary research schools, the vital importance of linking theory and practice in education through schools has been an integral part of the IOE’s values and ethos. One way to link theory to practice is to utilise participatory research methodologies to embed evidence in practice. This article discusses the research project Manor Park Talks, undertaken in collaboration with IOE and a leading partner, a head teacher and IOE alumnus of the East London Teaching and Research School. The aim of the project was to support early language and communication in a cluster of early years settings in Newham, London, and it involved a process of co-production in the design of a systematic review to assess the evidence-based pedagogical strategies that can be used to inform teaching practices to enhance the professional development of early years education practitioners (to include teachers, classroom assistants, childcare workers and other ancillary staff). The research aimed to evaluate a community of practice for early years practitioners to support young children’s early language development and communication, and to inform an evidence-based practice tool to guide teaching practices in early years settings. A commentary on the review findings and methodological innovation of the study in using a participatory approach to review the evidence is provided in this article.

Published: September 2022

Graph query services (GQS) are widely used today to interactively answer graph traversal queries on large-scale graph data. Existing graph query engines focus largely on optimizing the latency of a single query. This ignores significant challenges posed by GQS, including fine-grained control and scheduling during query execution, as well as performance isolation and load balancing in various levels from across user to intra-query. To tackle these control and scheduling challenges, we propose a novel
scoped
dataflow for modeling graph traversal queries, which explicitly exposes concurrent execution and control of any subquery to the finest granularity. We implemented Banyan, an engine based on the scoped dataflow model for GQS. Banyan focuses on scaling up the performance on a single machine, and provides the ability to easily scale out. Extensive experiments on multiple benchmarks show that Banyan improves performance by up to three orders of magnitude over state-of-the-art graph query engines, while providing performance isolation and load balancing.
Misinformation mitigation under differential propagation rates and temporal penalties
Authors: Simpson Michael , Hashemi Farnoosh , Lakshmanan Laks V. S.
Published: September 2022

We propose an information propagation model that captures important temporal aspects that have been well observed in the dynamics of fake news diffusion, in contrast with the diffusion of truth. The model accounts for differential propagation rates of truth and misinformation and for user reaction times. We study a time-sensitive variant of the
misinformation mitigation
problem, where
k
seeds are to be selected to activate a truth campaign so as to minimize the number of users that adopt misinformation propagating through a social network. We show that the resulting objective is non-submodular and employ a sandwiching technique by defining submodular upper and lower bounding functions, providing data-dependent guarantees. In order to enable the use of a reverse sampling framework, we introduce a weighted version of reverse reachability sets that captures the associated differential propagation rates and establish a key equivalence between weighted set coverage probabilities and mitigation with respect to the sandwiching functions. Further, we propose an offline reverse sampling framework that provides (1 - 1/
e
- ϵ)-approximate solutions to our bounding functions and introduce an importance sampling technique to reduce the sample complexity of our solution. Finally, we show how our framework can provide an anytime solution to the problem. Experiments over five datasets show that our approach outperforms previous approaches and is robust to uncertainty in the model parameters.
Notes Towards a Close Reading of David Lowery’s 2021 Film

The Green Knight
Authors: Harty Kevin J.
Published: September 2022

This essay offers a close reading of David Lowery’s 2021 film The Green Knight suggesting that the director has consciously subverted the text of his source to produce an always intriguing film whose debts to the medieval are many. Unlike previous directors whose ‘Gawain’ films failed even to engage with their medieval source, Lowery follows details in his source when it suits his purpose, but, more often than not, he adds scenes to, or deletes scenes from, the fourteenth-century Middle English poem. His additions are especially noteworthy in how they offer an alternate, perhaps even a queer, reading of the poem. Lowery’s goal seems to be to retell a basically linear tale in a more convoluted and circular manner thereby calling into question viewers’ thematic and narrative expectations. At the same time, Lowery’s film can be read as an antidote to the toxic masculinity found in so many other Arthurian texts across multiple genres.
Performance enhancement of 8 channel SCM–WDM based RoF link using different type of transmission fibers along with different type of channel spacing
Authors: Sharma Neha , Kaur Baljeet , Grewal Narwant Singh
Published: September 2022

A system is represented that uses 20 nm of channel spacing and unequal channel spacing along with four different types of transmission fibers on subcarrier multiplexing–wavelength division multiplexing (SCM/WDM) based radio over fiber (RoF) link. These five different kinds of fibers have been analyzed offering different propagation parameters. In case of 20 nm of channel spacing the performance of the link is improved by 35.32% with the use of True wave fiber. In this paper, 8 channel SCM–WDM based RoF based model is simulated and analyzed with different type of optical fibers covering distance of 10 km. A comparison of Q-factor at different optical power and different optical lengths has been made. Q-factor, bit error rate and eye diagrams have been examined for assessing the performance of the model.

Authors: Williams Brinley M. , Le Poidevin Lindsey M. , Turrentine Mark A. , Antoniewicz Leah W.
Published: September 2022

Objectives

To assess the quality and content of information regarding external cephalic version on YouTube.

Methods

YouTube was searched using the phrase “external cephalic version” (ECV) to identify informative videos by two independent reviewers. Videos were included if: (1) in English; (2) available November 20, 2021; (3) related to ECV. Videos were excluded if: (1) duration exceeded 15 min; (2) target audience was not patients or the general public; (3) not in English; (4) were advertisements or news clips; (5) did not relate to ECV. The Global Quality Scale was used to assess overall quality of selected videos. A content score was developed based on guidelines from the American College of Obstetricians and Gynecologists. Video quality was also categorized as “slightly useful”, “useful” and “very useful”. The Patient Education Materials Assessment Tool (PEMAT) for audiovisual materials was used to score understandability and actionability.

Results

Of 60 videos screened, 31 met inclusion criteria. They were classified as People or Blogs (n=19, 61%) or Education (n=12, 39%). Videos were calculated to be “slightly useful” (n=10, 32%), “useful” (n=18, 58%), or “very useful” (n = 3, 10%). The PEMAT – understandability was less in the “slightly useful” compared to the combined “useful” and “very useful” groups, p<0.01. No differences existed between total usefulness score and category, p=0.6.

Conclusions

Most videos were useful, but few were very useful. These results highlight the importance of thorough counseling regarding this procedure.

Published: September 2022

Tetracycline (TecH2) reacts with triphenylantimony (TPSbiii) in the presence of hydrogen peroxide to form the [Ph3Sbv(Tec)] (TecAn). The sodium penicillin G (PenH) conjugates with Ag(i) towards [Ag(Pen)(MeCN)]2(PenAcAg).TecAnandPenAcAgwere characterized by melting point, X-ray fluorescence spectroscopy, attenuated total reflectance-Fourier transform infra-red, thermogravimetric-differential thermal analysis in solid state, ultraviolet-Vis spectroscopy, and nuclear magnetic resonance (1H and13C-NMR), spectroscopies in solution. The molecular weight was determined with cryoscopy. Thein vitrocytotoxic activity ofTecAnandPenAcAgwas evaluated against the human breast adenocarcinoma cell lines: MCF-7 (positive to hormones receptor (HR+)), MDA-MB-231 (negative to hormones receptor (HR−)), and theirin vitrotoxicity and genotoxicity were tested against normal human fetal lung fibroblast cells (MRC-5). The MCF-7 cells’ morphology and acridine orange/ethidium bromide staining suggest an apoptotic pathway for cell death. The binding affinity ofTecAnandPenAcAgwith DNA was, ex vivo, studied by UV-Vis and fluorescence spectroscopy and viscosity measurements of DNA solution.PenAcAginhibits lipoxygenase (LOX) stronger than cisplatin, while no inhibitory activity has been detected forTecAn. The reduction of non-active Sb(v), ofTecAn, to active Sb(iii) by glutathione (a tripeptide over expressed in tumor cells) was also investigated.

Published: September 2022

En Nuevo León, México, se decretaron tres áreas naturales protegidas (ANP) para conservar a Cynomys mexicanus; sin embargo, las actividades agropecuarias continúan dentro de estas áreas, aunado a la carencia de información sobre la condición de su hábitat. En este estudio se evaluó la salud del pastizal y la producción de biomasa de las tres áreas (la Trinidad, la Hediondilla y Llano la Soledad) para determinar su funcionalidad. La salud del ecosistema de La Hediondilla estuvo deteriorad y su zona núcleo presentó el estado funcional más crítico; además, presentó la mayor producción de biomasa (0.53 Mg/ha-1) debido al cambio de uso de suelo y la vegetación invasora. Las actividades productivas en el Llano La Soledad son básicamente ganaderas, aunque la producción de biomasa fue menor (0.14 Mg/ha-1), presentó las mejores condiciones de salud, ya que toda su superficie es de uso restringido. La salud deteriorada del pastizal es una amenaza para Cynomys mexicanus y la biodiversidad de su ecosistema.
Pi USB Cam: A Simple and Affordable DIY Solution That Enables High-Quality, High-Throughput Video Capture for Behavioral Neuroscience Research
Authors: Hou Shikun , Glover Elizabeth J.
Published: September 2022

Video recording is essential for behavioral neuroscience research, but the majority of available systems suffer from poor cost-to-functionality ratio. Commercial options frequently come at high financial cost that prohibits scalability and throughput, whereas DIY solutions often require significant expertise and time investment unaffordable to many researchers. To address this, we combined a low-cost Raspberry Pi microcomputer, DIY electronics peripherals, freely available open-source firmware, and custom 3D-printed casings to create Pi USB Cam, a simple yet powerful and highly versatile video recording solution. Pi USB Cam is constructed using affordable and widely available components and requires no expertise to build and implement. The result is a system that functions as a plug-and-play USB camera that can be easily installed in various animal testing and housing sites and is readily compatible with popular behavioral and neural recording software. Here, we provide a comprehensive parts list and step-by-step instructions for users to build and implement their own Pi USB Cam system. In a series of benchmark comparisons, Pi USB Cam was able to capture ultra-wide fields of view of behaving rats given limited object distance and produced high image quality while maintaining consistent frame rates even under low-light and no-light conditions relative to a standard, commercially available USB camera. Video recordings were easily scaled using free, open-source software. Altogether, Pi USB Cam presents an elegant yet simple solution for behavioral neuroscientists seeking an affordable and highly flexible system to enable quality video recordings.
Protesta estudiantil en la crisis universitaria de 1971 en Colombia: la Juventud Patriótica (JUPA) y la Nueva Izquierda
Authors: Acevedo Tarazona Álvaro , Lagos Cortés Emilio
Published: September 2022

Durante el año 1971, en Colombia se vivió un intenso movimiento de protesta estudiantil que paralizó casi la totalidad del sistema universitario, aunque se desarrolló de acuerdo con las lógicas locales de cada institución de educación superior. El propósito de este artículo es analizar los espacios de acción y discusión ideológica de la organización política Juventud Patriótica (JUPA), la cual cuenta con estrategias de difusión y programas políticos que llevarán a legitimar decisiones en favor de la movilización estudiantil y a asumir posiciones ideológicas irreconciliables entre los actores de la izquierda de tendencia socialista. Este periodo de la historia del movimiento estudiantil ha sido analizado, con cierta profundidad, en instituciones como la Universidad Nacional de Colombia, la Universidad Libre, la Universidad Industrial de Santander (UIS), la Universidad del Valle y la Universidad Pedagógica y Tecnológica de Colombia (UPTC). Para alcanzar el objetivo propuesto se realiza el análisis de folletos y periódicos universitarios como Nueva Democracia y documentos que se encuentran en el Archivo de la Asociación Universitaria de Estudiantes Santandereanos (Audesa). Estos documentos dan cuenta de que fuerzas políticas como la JUPA influyen en estudiantes, profesores y trabajadores para desarrollar su programa político al interior de las universidades colombianas.

Authors: Kusuma I Putu Indra
Published: September 2022

This study aimed at investigating the EFL preservice teachers’ technology integration in managing and teaching speaking skills online during emergency remote teaching in Indonesia. This study employed a single case study approach by implementing an explanatory sequential mixed method design. The findings showed that even though the preservice teachers used various technology tools, they frequently implemented WhatsApp, YouTube, and Google Forms for classroom management and teaching speaking purposes. This study offers some implications to advance English language teacher education programs to prepare the future EFL preservice teachers in the post-pandemic era.
Refortalecimiento: Beyond prevention, Empowerment and Intervention in an Impoverish Community in Puerto Rico
Authors: Vázquez-Rivera Carlos Enrique , Rojas-Livia Jacquelinee Gresse
Published: September 2022

Refortalecimiento is a strategy for transformation that started with a debate with the empowerment theory. We have been clarifying the notion of refortalecimiento from experiences at communities and academic’s scenarios. As a result, we need to re-imagine some of our concepts to address the consequences of inequalities. In this article, we will present some reflections about three concepts: intervention, prevention model, and empowerment theory based in an Intervention-Investigation (I-I) realized in a community with a group of mothers of children with disabilities (diverse abilities) in an impoverish community in Puerto Rico. We confirmed the need to reevaluate the impact of different concepts/perspectives operating within the project that undermine the implementation process. We learned that the beauty of this process resides on the reciprocity and the fortalezas (strengths) that takes place within all the people involved. But we also find out neoliberal values as: individualism, competition, and everyone for themselves presented great obstacles to overcome discrimination and disparities.

Published: September 2022

Filipinos are said to have high esteem for the lighter skin complexion, and lower esteem for the darker one. By manipulating the skin colors some digitally created photographs of non-existent models, this paper empirically and quantitatively explored this Filipino attitude by surveying 527 respondents from Metro Manila, the metropolitan capital of the Philippines. This research was able to validate the Filipinos’ higher esteem for lighter skin complexion in general. However, generational variation was detected in the sense that Generation x respondents have a higher esteem for the lighter skin complexion, while Generation z respondents no longer have. Furthermore, gender variation was also detected in the sense male respondents have a wider divergence on how they highly esteem the lighter skin complexion against the darker one, compared to their female counterparts. This paper is significant in empirically documenting this Filipino esteem for the lighter skin color, as well as in pointing out that such esteem is shaped by generational and gender variations among the respondents.

Published: September 2022

This study aims to characterize video game use disorder in adolescents, identifying the particularities of those who present it, its effects at the brain level, related factors, and existing measurement instruments. A systematic review of the scientific publications available in Scopus was carried out, between the period 2014-2018 on video game use disorder in adolescents. Adolescents with this disorder are characterized by being mostly men, spending more time daily and weekly playing than adolescents without this disorder, showing diverse symptoms in the behavioral, affective, and cognitive areas. At brain level, it is referred that in this disorder there is an increase and decrease in the activation of specific areas of the brain. Likewise, the presence of some psychological disorder and impulsivity are considered factors that increase the risk of suffering from it. However, there are protective factors as school commitment and parental supervision, among others.

Biological homochirality and stoichiometric network analysis: Variations on Frank’s model
Authors: Ágreda Bastidas Jesús Alberto , Montoya Arguello Juan Andrés , Mejía Carolina
Published: September 2022

Biological homochirality is modelled using chemical reaction mechanisms that include autocatalytic and inhibition reactions as well as input and output flows. From the mathematical point of view, the differential equations associated with those mechanisms have to exhibit bistability.  The search for those bifurcations can be carried out using stoichiometric network analysis. This algorithm simplifies the mathematical analysis and can be implemented in a computer programme, which can help us to analyse chemical networks. However, regardless of the reduction to linear polynomials, which is made possible by this algorithm, in some cases, the complexity and length of the polynomials involved make the analysis unfeasible. This problem has been partially solved by extending the stoichiometric matrix with rows that code the duality relations between the different reactions occurring in the network given as input. All these facts allow us to analyse 28 different network models, highlighting the basic requirements needed by a chemical mechanism to have spontaneous mirror symmetry breaking.

Published: September 2022

This study evaluates the Tertiary Education Trust Fund (TETFund) intervention projects and space utilisation in Nuhu Bamalli Polytechnic (NUBAPOLY) Zaria of Kaduna state, Nigeria. The study relates to the funding and utilisation of physical projects in NUBAPOLY. The study population consisted of all the twenty-one (21) staff of the physical planning department of Nuhu Bamalli Polytechnic, Zaria. The respondents were selected based on a convenience sampling technique. A total of 21 copies of the questionnaire were administered and retrieved from the respondents. The data collected were analysed using descriptive statistics. Findings from the study revealed that the construction of new buildings (52.4%) and the provision of laboratory equipment and furniture (33.7%) had the highest allocation of funds, respectively. The overall space utilisation for NUBAPOLY is 43.60%. In comparison, renovation of buildings had the least (1.0%). Based on these findings, it was recommended that TETFund should ensure adequate utilisation of its intervention projects through supervision and inspection. The management of Nuhu Bamalli Polytechnic should make optimum utilisation of TETFund intervention projects, especially on the Main and Annex campuses, to improve the quality of education.
