Applying Electrical Impedance Tomography Techniques for Detection of Decay Inside Trees
Authors: KIEU Duy Thong , VU Hong Duong , NGUYEN Thi Thu Hang , NGUYEN Thu Thuy
Published: January 2022

Trees play a critical role in creating green spaces in public areas such as streets, parks, schools,offices. Over time, the trees often get pests and diseases, and then rotten trees can break. To care for andconserve the trees, it is necessary to determine the condition inside the trunk, especially the possibility ofhaving a hollow or not. Wood decay, modifications of moisture and ion content, density due to biotic andabiotic stress agents of water extremity, salinity, and infection strongly change (di-) electrical propertiesof wood. Hence, we propose to use electrical impedance tomography to detect the change in electricalproperties inside the trees that can link to wood decay. In electrical impedance tomography, an array ofelectrodes is attached around the tree trunk, and small alternating currents are injected via these electrodes,so the resulting voltages are measured. Processing the data, we can construct the spatial distribution ofimpedance (or resistivity) of the object. In this work, we will present the preliminary results of our groupresearch. We will show theoretical forward modeling results, followed by laboratory experiments and realdata application. The results illustrate that electrical impedance tomography can be useful to define severaldecay scenarios inside the trees.

Published: January 2022

Blasting is an indispensable part of the open pit mining operations. It plays a vital role inpreparing the rock mass for subsequent operations, such as loading/unloading, transporting, crushing, anddumping. However, adverse effects, especially blast-induced ground vibrations, are considered one of themost dangerous problems. In this study, artificial intelligence was supposed to predict the intensity ofblast-induced ground vibration, which is represented by the peak particle velocity (PPV). Accordingly, anartificial neural network was designed to predict PPV at the Coc Sau open pit coal mine with 137 blastingevents were collected. Aiming to optimize the ANN model, the modified version of the particle swarmoptimization (MPSO) algorithm was applied to optimize the ANN model for predicting PPV, called theMPSO-ANN model. For the comparison purposes, two forms of empirical equations, namely UnitedStates Bureau of Mining (USBM) and U Langefors - Kihlstrom, were also developed to predict PPV andcompared with the proposed MPSO-ANN model. The results showed that the proposed MPSO-ANNmodel provided a better performance with a mean absolute error (MAE) of 1.217, root-mean-squared error(RMSE) of 1.456, and coefficient of determination (R2) of 0.956. Meanwhile, the empirical models onlyprovided poorer performances with an MAE of 1.830 and 2.012, RMSE of 2.268 and 2.464, and R2 of0.874 and 0.852 for the USBM and U Langefors – Kihlstrom empirical models, respectively.

Ingresar a la comunidad de Pucahuaico es el encuentro con las voces silenciosas de adultos/as mayores. Es sobre esta población que el artículo propone algunas reflexiones sobre la violencia simbólica inmersa en la calidad de vida, en el abandono, soledad, pobreza, condición física y de salud, afectando el ejercicio de sus derechos y dignidad, evidenciados en la complejidad social, su interrelación con la comunidad, el acceso a servicios, vivienda, alimentos, lengua de origen y desempleo que permanece invisible y naturalizado en las prácticas diarias.

En este sentido, el estudio realizado durante el período 2019- 2020, analiza estas condiciones en dos momentos; el primero a través de una encuesta sociocontextual de percepción sobre la violencia y el segundo a través de historias de vida en grupos focales de adultos/as mayores que reflejan que la percepción de la violencia simbólica permanece casi imperceptible en su calidad de vida. Así, el interés de socializar y visibilizar su realidad, para interpelar al Estado ecuatoriano sobre una política pública adecuada en temas de prevención, mecanismos de protección, promoción de los derechos humanos y garantías efectivas en favor del adulto/a mayor, que permitan recuperar sus voces, su memoria e identidad como parte del compromiso y de la corresponsabilidad social.

Los resultados señalan la presencia de enfermedades crónicas propias de la vejez, abandono familiar, desánimo, depresión y soledad en la población de adultos mayores, así como la ausencia del estado en la atención de la salud. Hay evidencia de discriminación basada en su etnia y en la edad, así como explotación laboral por actividades de cuidado no remuneradas, discriminación que en su mayoría proviene de su propio entorno familiar y de su comunidad. Por otra parte, los resultados señalan reflejan un proceso de a culturización basado en la idea peyorativa de ser indígena, lo que se expresa en la presión social al interior de las familias para dejar atuendos, lenguaje e idiosincrasia proveniente de los pueblos originarios, por otro lado, una corriente de recuperación de la identidad cultural desde los colectivos presentes y el gobierno local.

Orbital defects with total loss of eyelids and the eyeball cannot be satisfactorily repaired by reconstructive surgery. Therefore, a prosthetic placement is the treatment of choice to return the individual’s confidence by producing an acceptable and lifelike appearance. Male patient, 31 years old, came with history of exenteration surgery four months ago on right eye because of infection few years before. Patient wanted orbital prosthesis to improve esthetic and self-confidence. He lost his right eye ball and some part of right eyelid. Treatment of choice that would be fabricated was orbital prosthesis with medical adhesive retention support. Orbital prosthesis was one of the alternative that can be chose to reconstruct orbital defect. The success of the prosthesis was determined by the exactness of diagnosis, treatment plan determination, material selection, determination of prosthesis retention, and technique in processing the prosthesis.

Published: January 2022

Rice (Oryza sativa L.) is a staple food crop in many countries in Africa. Africa consumes 11.6 million tons of rice per annum and out of 39 rice-producing countries, 21 import 50% to 99% of their rice requirements. The inability to reach the yield potential that would sustain Africa’s need for rice is due to many biotic and abiotic constraints that rice production faces. In lowland grown rice, one of the abiotic factors hindering rice production is iron toxicity. Excess uptake of ferrous (Fe2+) ions leads to a physiological stress, which results, into poor production. The current study aimed at selection of varieties tolerant to iron toxicity and assessment of the genetic diversity linked to this trait. In a hydroponic experiment conducted in a screen house at Africa Rice Centre in Dar es Salaam, 32 rice varieties were evaluated for tolerance to iron toxicity. The experiment was laid out in a split plot design with iron concentration as the main plot factor and variety as the sub plot factor. Two levels of iron concentration were used: 2 ppm and 300 ppm of Fe2+ as control and test concentrations, respectively. Traits observed to gauge tolerance were leaf bronzing (an indicator of iron toxicity), plant height, tillering, number of leaves, shoot weight (above ground), root length and root weight. The varieties ARICA8, and CK801 were found to be tolerant due to low bronzing indices, higher shoot weight, more number of leaves and lack of significant variation in morphology between the two Fe treatments except for the plant height. Correlation analysis depicted negative correlation between leaf bronzing and the other traits measured especially shoot biomass.

Authors: Chernov Y. G. , Zholdasova Zh. A.
Published: January 2022

The aim of the research. Alzheimer’s disease is the most common form of dementia. One of the potential tools for early detection of the onset of the disease is the handwriting analysis. It can be a warning signal for a serious medical investigation. The dynamics of handwriting changes are also a good indicator of the progression of the disease and the eff ectiveness of therapy.

Methods. The authors have developed two corresponding tests. The fi rst (AD-HS) allows the assessment of handwriting markers of cognitive impairment and Alzheimer’s disease from an available handwriting sample. The second (ADHC) is designed to assess dynamics by comparing two handwritten documents written at diff erent times.

Results. The pilot study includes 16 patients who were found to be at diff erent stages of the disease by medical examination. They all provided old handwriting samples dated 10–20 years ago and new handwriting samples specifi cally written as part of the experiment. Evaluation of 36 handwriting characteristics showed that both tests were eff ective in identifying Alzheimer’s disease and its stage. The correlation between the handwriting analysis and the medical test result was 0.62.

Conclusion. Further refi nement of the proposed tests and expansion of the research base will enable handwriting exercises to be incorporated into supportive therapy to slow the progression of the disease.

The modern integrated approach to the treatment of ischemic stroke (IS), in addition to pharmacotherapy, provides for the impact of physical factors. Among them is injectable carboxytherapy (ICBT).

Objective. The aim of the study was to evaluate the effi cacy and safety of using ICBT in combination with a standard treatment program in patients with acute ischemic stroke.

Material and methods. The main group (MG) included 39 patients with acute IS, the comparison group (GC) — 31 patients. On the second day of hospitalization, patients with MG underwent ICBT on the background of standard therapy, and GC — procedures that mimic ICBT. Clinical, laboratory and instrumental data, IS outcomes, complications, timing were assessed.

Results. There were no statistically signifi cant diff erences in physiological parameters (heart rate, blood pressure, SpO2) between MG and GC during and after the course of treatment. Positive dynamics of the neurological status was observed in both groups in the form of a decrease in the NIHSS score — in the MG from 6 to 4 (p = 0.047), in the GC — also from 6 to 4 (p = 0.25). In patients with MG, trophic disorders were less likely to develop in comparison with GC — 1 (2.6%) versus 6 (19.4%), p = 0.039. ICBT did not aff ect the duration of hospitalization of patients, the duration of treatment in the intensive care unit and carrying of resuscitation and also did not contribute to reducing mortality. Changes in the indicators of the acid-base state of the blood were compensatory in nature and did not lead to changes in the pH of the blood. The decrease in pH from 7.5 to 7.4 in 30–90 minutes after the procedures was a physiological reaction of the body to the introduction of CO2 and was not accompanied by negative consequences.

Conclusions. ICBT is a safe method, does not aff ect the duration of hospital stay and mortality, help lower the likelihood of complications.

Published: January 2022

Literatürde, genel olarak yükseköğretim hizmetinden yaralananların çoğunluğunun yüksek gelirli ailelerin çocukları olduğu, düşük gelirli ailelerinin çocuklarının temsil oranının ise düşük olduğu kabul edilmektedir. Özellikle girişin sınav ile olduğu yükseköğretim sistemlerinde yüksek gelirli aileler, hazırlık kursları biçimindeki örtülü fiyat mekanizması yoluyla sınavı kendi lehlerine çevirebilirken, düşük gelirli aileler vergiler yoluyla finansmana katıldığı halde yükseköğretim hizmetlerinden yararlanamamaktadır. Bu durum, kamusal yükseköğretim harcamaları yoluyla gelirin düşük gelirlilerden yüksek gelirlilere doğru yeniden dağıtılmasına neden olurken, yüksek gelir gruplarına gizli bir gelir transferi yaratmaktadır. Kaynağın düşük gelir grubunun da dâhil olduğu bütün vergi mükelleflerinden toplanması buradaki temel sorunu oluşturmaktadır.

Bu araştırmanın amacı, OECD üyesi ülkelerde 2000-2019 dönemi kamusal yükseköğretim harcamaları, vergiler ve gelir dağılımı ilişkisini panel ARDL testi ile analiz etmektir. Değişkenler arasındaki uzun dönemli ilişkinin tespiti için eş bütünleşme testi uygulanmış ve değişkenler arasında uzun dönemli ilişki saptanmıştır. Eş bütünleşmenin varlığının ardından Dumitrescu-Hurlin panel nedensellik testi yapılmış, kamusal yükseköğretim harcamalarından ve vergilerden gelir dağılımına doğru tek yönlü; vergilerden de kamusal yükseköğretim harcamalarına doğru tek yönlü nedensellik olduğu görülmüştür. Tahmin katsayısını belirlemek için Fixed etkiler modeli uygulanmış, yükseköğretim harcamalarında meydana gelen %1’lik değişimin 1.38 birim, vergilerde meydana gelen %1’lik değişimin de 1.05 birim gelir dağılımı adaletini sağladığı tespit edilmiştir.

Published: January 2022

The rapid development of the construction world in Indonesia has led to an increase in supporting technology that is more effective and efficient. The Building Information Model (BIM) technology that begins with the creation of an as-built 3D model, this model describes the existing condition of the building. The Terrestrial Laser Scanner (TLS) method can provide a point cloud with a decent point density, but there are still areas of the building that aren't covered, such as the roof. To be more complete and detailed, additional data is needed using an Unmanned Aerial Vehicle (UAV). The results of the combination of TLS and UAV complement each other so that the results of the point cloud can form more detailed buildings. BIM may be built by combining these two data sets, allowing for the three-dimensional depiction of assets in buildings. The registration results for TLS point cloud data have a fairly good value where the overlap value is 44.9% (minimum 30%), balance is 41.2% (minimum 20%), points < 6mm is 98.9% (minimum 90%). The measurement results using the UAV have an RMSE GCP value of 0.266m and an RMSE ICP of 0.455m. Merging the results of TLS and UAV measurements is done using 3DReshaper software with four align points. The final result of making the BIM model is obtained level of detail (LOD) 3 where room models such as columns, floors, stairs, and walls are well depicted, while asset models such as furniture are also depicted although they are still simple objects.

Tujuan utama dari robot ini adalah bernavigasi dan mencari bola sampai kearah gawang lawan.  Robot sepakbola beroda merupakan salah satu kategori robot yang pertama kali dipertandingkan pada KRI (Kontes Robot Indonesia) 2018 kategori KRSBI (Kontes Robot Sepakbola Indonesia) Beroda. Robot sepakbola dikembangkan agar memiliki fungsi yang mirip dengan pemain sepakbola pada umumnya yaitu mengejar bola, menggiring bola, dan menendang bola. Salah satu permasalahan yang masih dikembangkan sampai saat ini adalah bagaimana robot mampu mendeteksi bola menggunakan sensor kamera (webcam). Deteksi bola merupakan salah satu langkah awal dalam menentukan aksi selanjutnya robot sepakbola beroda seperti mengejar, menggiring, dan menendang bola. Karena bola yang digunakan pada pertandingan berwarna oranye maka pada penelitian ini dikembangkan pendeteksian bola menggunakan metode filter warna. Robot penjaga gawang bertugas untuk dapat menghadang bola berwarna oranye memasuki gawang. Robot tersebut harus mampu mendeteksi bola dengan akurat untuk menentukan pergerakan robot selanjutnya. Artikel ini mendeskripsikan pengembangan robot penjaga gawang yang mampu mendeteksi warna dan bentuk bola dengan metode HoughCircle dan approxPolyDP.

Spike sorting: new trends and challenges of the era of high-density probes
Authors: Buccino Alessio , Garcia Samuel , Yger Pierre
Published: January 2022

Recording from a large neuronal population of neurons is a crucial challenge to unravel how information is processed by the brain. In this review, we highlight the recent advances made in the field of “spike sorting”, which is arguably a very essential processing step to extract neuronal activity from extracellular recordings. We more specifically target the challenges faced by newly manufactured high-density multi-electrode array devices (HD-MEA), e.g. Neuropixels probes. Among them, we cover in depth the prominent problem of drifts (movements of the neurons with respect to the recording devices) and the current solutions to circumscribe it. In addition, we also review recent contributions making use of deep learning approaches for spike sorting, highlighting their advantages and disadvantages. Next, we highlight efforts and advances in unifying, validating, and benchmarking spike sorting tools. Finally, we discuss the spike sorting field in terms of its open and unsolved challenges, specifically regarding scalability and reproducibility. We conclude by providing our personal view on the future of spike sorting, calling for a community-based development and validation of spike sorting algorithms and fully automated, cloud-based spike sorting solutions for the neuroscience community.

To date, affective disposition and cognitive processing of emotional stimuli in individuals with depressive symptoms have not been fully explored within the same framework. Time-frequency analysis of electroencephalographic activity allows to disentangle the brain's parallel processing of information. The present study employed a time-frequency approach to simultaneously examine affective disposition and cognitive processing during the viewing of emotional stimuli in dysphoria. Time-frequency event-related changes were examined during the viewing of pleasant, neutral and unpleasant pictures in 24 individuals with dysphoria and 24 controls. Affective disposition was indexed by delta and alpha power, while theta power was employed as a correlate of cognitive elaboration of the stimuli. Cluster-based statistics revealed a centro-parietal reduction in delta power for pleasant stimuli in individuals with dysphoria than controls. Also, dysphoria was characterized by an early fronto-central increase in theta power for unpleasant stimuli relative to neutral and pleasant. Instead, controls were characterized by a late fronto-central and occipital reduction in theta power for unpleasant stimuli relative to neutral and pleasant. The present study granted novel insights on the interrelated facets of affective elaboration in dysphoria, mainly characterized by an hypoactivation of the approach-related motivational system and a sustained facilitated cognitive processing of unpleasant stimuli.

Authors: Paes Tanya Maria , Ellefson Michelle Renee
Published: January 2022

There is a need for more evidence-based research in education and research; however, the difficulty of conducting interventional research in educational settings is often less acknowledged. This article provides practical examples when implementing school-based interventions, and highlights the importance of designing a multifaceted, cost-effective intervention, especially when working with hard-to-reach families. Additionally, the article notes the importance of being consistent and attentive to the developmental stage of the children and supporting parental engagement, two aspects that are crucial to the implementation of the intervention. The article also provides suggestions for building the researcher-practitioner relationship from study onset, and outlines the use of scaffolding, positive reinforcement, and play-based learning strategies over the course of the intervention to support child outcomes.
Accuracy and Precision of Fixed and Random Effects in Meta-Analyses of Randomized Control Trials for Continuous Outcomes
Authors: Gnambs Timo , Schroeders Ulrich
Published: January 2022

Meta-analyses of treatment effects in randomized control trials are often faced with the problem of missing information required to calculate effect sizes and their sampling variances. Particularly, correlations between pre- and posttest scores are frequently not available. As an ad-hoc solution, researchers impute a constant value for the missing correlation. As an alternative, we propose adopting a multivariate meta-regression approach that models independent group effect sizes and accounts for the dependency structure using robust variance estimation or three-level modeling. A comprehensive simulation study mimicking realistic conditions of meta-analyses in clinical and educational psychology suggested that imputing a fixed correlation .8 or adopting a multivariate meta-regression with robust variance estimation work well for estimating the pooled effect but lead to slightly distorted between-study heterogeneity estimates. In contrast, three-level meta-regressions resulted in largely unbiased fixed effects but more inconsistent prediction intervals. Based on these results recommendations for meta-analytic practice and future meta-analytic developments are provided.
