Los sistemas de almacenamiento inka de Tinyaq, Ayacucho, Perú
Authors: Valdés Lidio , Valdés Juan Ernesto
Published: November 2022

Un aspecto de la arqueología regional de Ayacucho que ha recibido poca atención de los arqueólogos, es el caso de la ocupación inka. Si bien el valle de Ayacucho formó parte del Tawantinsuyo, poco es lo que se sabe del rol del mismo dentro de la política administrativa inka. Los varios trabajos de reconocimiento arqueológico realizados en el valle, solamente han dado como resultado la ubicación de muy pocos asentamientos inka. En base a esta información, a menudo se sostiene que el valle en referencia no jugó rol alguno dentro del esquema imperial inka. Sin embargo, la ubicación de los sistemas de almacenamiento de Tinyaq sugiere que este valle no fue del todo abandonado, como muchos sostienen. En este ensayo, es nuestro propósito evaluar el significado de los depósitos de Tinyaq. En base a esta información, sugerimos que el valle de Ayacucho formó parte de las zonas productivas del Tawantinsuyo.

Yaĉapa

Le texte en quechua de Ferreñafe, que nous présentons ici en trois versions, essaie d’illustrer les différentes étapes qu’un document de la tradition orale doit traverser depuis l’enregistrement original jusqu’à sa reformulation en texte littéraire susceptible d’être incorporé dans des livres scolaires ou des anthologies. Les nombreux problèmes qui doivent être résolus comprennent la normalisation de l’orthographe d’un dialecte sans tradition écrite, la substitution des hispanismes quand cela semble convénient et, parfois, la reformulation des énoncés trop marqués par l’influence de l’acculturation bilingue. En outre, il faudrait résoudre le problème de l’élimination des éléments caractéristiques du style oral : la répétition excessive, les énoncés tronqués, les hésitations et les incohérences, sans perdre complètement la spontanéité de l’original.

Observations on the Diet of the Barn Owl in Quebrada de los Burros (Dept. of Tacna, Peru)

The analysis of pellets belonging to a barn owl (Tyto alba) provided a good idea of the diversity and abundance of vertebrates which had been consumed in a southernmost Peruvian coast locality. It appears that the raptor feeds on at least two species of rodents, one of bird and two of lizards. The ingestion by the owl of at least 1848 g of small vertebrate biomass leaded to the formation and regurgitation of 10 pellets. The results indicate that (in terms of biomass) rodents represent the main food item (72.95 %) among the collection of pellets analysed. The presence of lizard remains suggests the hypothesis that the predatory behaviour of the barn owl is not only nocturnal but also diurnal .

“How we learned to kill our brother” ? : memory, morality and reconciliation in Peru
Authors: Theidon Kimberly
Published: November 2022

In this article we explore how campesinos in Ayacucho (Peru), understand both the political violence that has contoured daily life since 1980 as well as the mandate to kill that arose within the context of the armed conflict between the Shining Path guerrilla, the Peruvian Armed Forces and the peasant civil defense patrols. Since 1995 we had conducted anthropological research in various rural communities in Ayacucho. We investigated how war shapes moral life, challenging concepts of acceptable human conduct and the very sense of what it means to live in a human community. We utilized a genealogical approach to analyze the origins of moral interpretations that are forged in specific contexts. Indeed, the moral frameworks that villagers recount syncretize elements of militant Christianity, psychocultural themes, and the appropriation of extra-local discourses in the process of both militarizing and demilitarizing daily life.

Published: November 2022

Utah’s abundant energy and mineral resources are used to heat homes, drive industry, and keep the lights on. Effectively managing these energy and mineral resources and their associated supply chains requires knowledge of their economic value and how they currently contribute to Utah’s economy. This report calculates the total economic contribution of Utah’s energy and mining industries for 2019 and 2020. Each industry makes substantial contributions to Utah’s gross domestic product, employment, and tax base. Collectively, these industries contributed over 10% to Utah's total Gross Domestic Product (GDP), supported over 7% of its jobs, and contributed 20% to state tax revenue. Not only do these industries produce sizable economic value, they also create high-paying jobs. Average wages for the energy and mining industries were calculated to be $22,415 (45%) and $13,652 (28%) above the overall state average wage, respectively.

THE OPERATING CHARACTERISTICS CURVE OF THE ACCEPTANCE SAMPLING OF TYPE-A BASED ON OUTGOING PERCENT DEFECTIVE LOT
Authors: Dewi Bahagia Rafika , Gunawan Fergyanto E , Alamsjah Firdaus
Published: November 2022

The common type-A of Operating Characteristics (OC) curve measures the consumer’s risk through the incoming quality. However, the proportion of defective can alter after the sampling process; hence, the measure of consumer’s risk is better described by the outgoing quality or lot quality of post sampling inspection. A modified OC curve is developed based on the outgoing quality for two applicable cases; returned samples to the lot and non-returned or destructive samples. This research aims to develop the algorithm and evaluate the alternative acceptance sampling plan for isolated lots by outgoing percent defective. For the returned samples, the acceptance sampling requires less sample than that based on the common OC-curve and is seen as an opportunity for sampling size reduction. The number of reduced samples varies depending on the input parameters: Acceptance Quality Level (AQL), Rejectable Quality Limit (RQL), producer’s risk (α), consumer’s risk (β), and lot size (N). For the non-returned sample, more sample size (n) is required, even more than that of using the Binomial distribution’s sample size, which has been considered conservative.

Twitter is one of the popular social media used to get news quickly and briefly. After the outbreak of the COVID-19 virus and the government's policy to vaccinate against COVID-19 in Indonesia, more and more public opinion has been expressed through tweets. This makes the topic of COVID-19 vaccination interesting for sentiment analysis. Through sentiment analysis, information in the form of text data can be extracted to classify information related to positive or negative opinions. In this study, the classification of public opinion on COVID-19 vaccination was carried out using the supporting vector machine method without and with lexicon-based features. The manual labeling data used were 2981 tweets. The results of the classification of public opinion on COVID-19 vaccination in Indonesia with a supporting vector machine without the lexicon feature obtained accuracy, g-mean and AUC of 83%, 50% and 61.35%, respectively. Meanwhile, with lexicon-based features, the performance of the supporting vector machine method for classifying public opinion on COVID-19 vaccination in Indonesia obtained accuracy, g-mean and AUC of 90%, 86.63% and 87%, respectively. Based on these results, the performance of the supporting vector machine method with lexicon-based features provides better results for the performance of classifying of public opinion on COVID-19 vaccination compared to supporting vector machines without lexicon-based features.

The aquaculture industry in Cilegon City is fairly substantial. In the year 2020, 230.09 tons of farmed fish were produced. In Cilegon City, fish production statistics is often used for each sub-district. So far, no research has been undertaken to examine the dependency of fish output from one district to the next. Spatial modeling is used to examine the spatial correlation of fish production data in each sub-district, making it easier to characterize observations in a sub-district and their relationships with other sub-districts. A semivariogram model was fitted using the fish production data, and it was discovered that fish production in the city of Cilegon followed the cubic model with model parameters C = 2.9891 and range a = 5.28. Furthermore, using this spatial model, assessment of fish production in a location, in this example Cilegon City, can be carried out in further research in an effort to see food security.

PT Bumimulia Indah Lestari found defects in the oil bottle packaging products it produces, which include perforated bottles, black spots on bottles, and defects on labels. The type of defect on the bottle label is the highest defect in the period from July to December 2021 compared to other defects. This research is focused on the problem of defects in the inverted label as the dominant defect of the entire defect label. Researchers use the DMAIC method to solve these problems. The improvement resulting from the DMAIC method is the manufacture of a jig tool called Jig Go No Go which aims to reduce the number of defects and increase productivity in bottle products. The implementation of the jig can reduce the defect label as a whole from 5.8% to 3.3% and the sigma value increases from 2.488 to 2.493.

Próceres de la historia: mitos, caos y drama en Memorias y olvidos de José de San Martín de Antonio Elio Brailovsky
Authors: Sandoval-León Osvaldo
Published: November 2022

El presente artículo se encarga de examinar el uso de los discursos históricos a través de la (re)construcción de los mitos en la obra teatral Memorias y olvidos de José de San Martín (1992) del argentino Antonio Elio Brailovsky. Para esto, nos enfocamos en el empleo de la parodia y la metateatralidad para reforzar la aproximación crítica de contextos sociopolíticos en el pasado y presente. De este modo, uno de los propósitos de este artículo radica en identificar la manipulación discursiva en ámbitos políticos que intentan enmascarar la precariedad en distintos sectores sociales. La obra de Brailovsky nos permite reflexionar sobre la circularidad en la opresión en el lenguaje que se viene dando desde la creación de la nación argentina.
Hybrid festivals: Challenges facing Cracow’s festival scene in times of pandemic
Authors: Kupis Marta , Golemo Karolina
Published: November 2022

The main goal of this paper is to show the strategies of dealing with the pandemic circumstances chosen by three of the city’s festivals: EtnoKraków/Crossroads, Sacrum Profanum, and Unsound. Emerging from their diverse approaches is a new hybrid festival formula, which brings with it brand new challenges. These include: new models of interaction between organisers, artists, and audiences; reorganisation of festival space; new patterns of audience accessibility and new forms of exclusion/openness; opportunities and barriers for (virtual) cultural exchange; and finally, a recalibration and blurring of the public and private dimensions brought about by the new types of festival experience. Indeed, it could even be argued that the live event sector is facing significant change in the very concept of “liveness”. The analysis is based both on existing data concerning processes of music festival production and consumption (press articles, reviews, and reports) and semi-structured interviews with artistic directors, managers and producers of the selected festivals, held in 2020/2021.
Nie-ludzkie sojusze, wiedza milcząca i „czucie wody”. Wytwarzanie olimpijczyka w perspektywie teorii aktora-sieci
Authors: Janas Krzysztof
Published: November 2022

Artykuł stanowi próbę wykorzystania teorii aktora-sieci w obszarze sportu. Na podstawie własnych doświadczeń pływaka wyczynowego i trenera jednego z najlepszych polskich pływaków pokazuję jak sport konstruowany jest w interakcjach i bezustannych negocjacjach z różnymi aktorami, a nie wyłącznie przez warunki społeczne, ekonomiczne i kulturowe. Opisuję też jak – poprzez manipulowanie i stabilizowanie swojego otoczenia, relacji z ludzkimi i nie-ludzkimi partnerami treningowymi oraz odwoływanie się do wiedzy milczącej – sportowiec realizuje swoje cele takie, jak udział w igrzyskach olimpijskich. Tekst wskazuje, że podążanie w procesie treningowym za zawodnikiem i jego materialnym środowiskiem daje nowy wgląd w sport wyczynowy: w jego pojmowanie, praktykowanie i socjotechniczne wytwarzanie. Przyglądając się z bliska przygotowaniom wyczynowca próbuję tym samym sproblematyzować wyobrażenie tego, co zawodnicy z trenerami faktycznie robią na treningach.
Władza partii czy papieża? Przesłanki i efekty zbliżenia watykańsko-chińskiego
Authors: Kowalski Bartosz
Published: November 2022

Większość z około 10 milionów katolików w Chińskiej Republice Ludowej skupiona jest w tzw. Kościele oficjalnym, a więc znajdującym się pod zwierzchnictwem chińskiego rządu i oficjalnie nieuznającym prymatu papieża. Pozostała część zrzeszona jest we wspólnotach Kościoła podziemnego, którego biskupi nie są desygnowani lub aprobowani przez chińskie władze. We wrześniu 2018 roku Watykan i Chińska Republika Ludowa osiągnęli tajne porozumienie, dzięki któremu papież uzyskał prawo głosu w kwestii nominacji biskupów w kościele oficjalnym, a w zamian Stolica Apostolska uznała, przynajmniej część, biskupów uprzednio desygnowanych przez władze komunistyczne. Niniejszy artykuł analizuje przesłanki zawarcia tej historycznej umowy, stanowiącej element postępującej normalizacji stosunków watykańsko-chińskich, oraz jej bezpośrednie konsekwencje, zarówno na poziomie bilateralnym, jak i dla stron trzecich – przede wszystkim Tajwanu, dowodząc, że w obecnej sytuacji porozumienie jest korzystne przede wszystkim dla Chińskiej Republiki Ludowej, zarówno w wymiarze praktycznym, jak i polityczno-propagandowym.

According to the well-known concept of consequential waves of terrorism, proposed by American researcher David C. Rapoport, since 1979, the world has encountered a wave of religious terrorism. Religiously motivated terrorists are the most dangerous and cruel terrorists who continue to lead the world. All four terrorist groups responsible for 55 per cent of total deaths in 2019 are jihadists (Global Terrorism Index 2020). The Taliban, Boko Haram, ISIL, and Al-Shabaab all fight for the establishment of their own quasi-state entities within the borders of existent sovereign states. This political objective associates the jihadists with another ideological movement – separatist-terrorists – in Rapoport’s model. Despite apparent distinctions in ideological foundations and political agendas, these two movements are similar in their struggle for self-determination within the borders of sovereign states. In this article, we use data from the Global Terrorism Database to compare how these two ideological movements with similar political objectives influence each other in the area of terrorist activity. Having analysed and reviewed information about 3,617 terrorist organisations that committed at least one terrorist attack from 1970 to 2018, we check how jihadist and separatist-terrorist activities were interrelated and how this interrelation manifested itself in different countries.

Published: November 2022

Previous theoretical studies have suggested novel approaches for enhancing the thermoelectric performance of Mg2Si, i.e. electronic band engineering based on tensile strain to enhance the Seebeck coefficient and electrical conductivity simultaneously. To realise this approach, we investigated the doping with isoelectronic impurities (Ca, Sr, and Ba) substituted at Mg sites. We performed variable-cell relaxation calculations for Ca-doped, Sr-doped, and Ba-doped systems using first-principles calculations. The results showed that doping with Ca made the lowest and next-lowest conduction bands approach each other, which is advantageous for enhancing thermoelectric properties. Thermoelectric calculations showed that the distribution of Ca atoms would have a crucial effect on thermoelectric properties. Although Ca doping did not improve the n-type power factor for any structures examined in the present study, the Seebeck coefficient increased for the p-type, especially for a certain structure at 300 and 600 K, resulting in an improved power factor.
Investigation of PVT variation on single-event transient effect assisted with hardened layout techniques

Published: November 2022

With the aggressively scaled technology, the single-event transient (SET) in the integrated circuits is regarded as one of the critical threats to the system reliability, where the hardening efficiency strongly depends on the randomness of striking positions and process-voltage-temperature (PVT) variations. To enhance the SET robustness and improve the immunity to PVT variations, different layout-based hardening techniques are proposed and compared. Moreover, the tolerance of PVT for hardened layouts and the underlying physics reasons are investigated by technology-computer-aided-design simulations. The simulation reveals that the techniques combining the split active area, gapless well and source, and the selectively implanted deep N-well enable to reduce the transient pulse width as well as mitigate the variations from PVT and hit position.
Enhancement of short-wavelength range responsibility for PIN silicon photodetectors using additional fluorescent carbon quantum dots nanoparticles
Authors: Huang Hao-Yun , Chen Jia-Hao , Nan Feng , Zhou Lei
Published: November 2022

We demonstrate a hybrid Si photodetector structure by employing an additional layer of fluorescent carbon quantum dot (CQD) nanoparticles constructed on the surface of a Si positive-intrinsic-negative (PIN) photodetector. The experimental studies reveal that the optimized hybrid device can efficiently enhance short-wavelength range responsibility between 300 nm to 600 nm without inducing any deteriorated photodetection performance beyond the short-wavelength region, and thereby achieve broadband sensitivity across the UV–vis-NIR spectra region. The measured photoresponsivity of the optimized device can achieve ∼0.088 A W−1 (@500 nm), which was ∼25% higher than that of a commercial blank PIN Si photodetector.

Pencapaian prestasi akademik siswa seolah-olah sebagai satu-satunya tolak ukur keberhasilan perkuliahan selama belajar di kampus. Prestasi Akademik mahasiswa, dalam hal ini taruna, antara lain dilihat dari Indeks Prestasi Kumulatif (IPK). Semakin tinggi nilai IPK taruna, maka diindikasikan pencapaiannya dalam bidang akademik bagus juga. Demikian pula sebaliknya, bila IPK-nya buruk, maka dapat menjadi indikasi bahwa taruna yang bersangkutan kurang berhasil dalam memahami materi kuliah yang disajikan selama semester perkuliahan. Penelitian ini dilakukan untuk mencari informasi dari taruna mengenai faktor apa saja yang mempengaruhi prestasi akademik mereka serta mencari akar permasalahan yang mempengaruhi pencapaian prestasi akademik tersebut sehingga didapat solusi agar pencapaian prestasi akademik taruna meningkat.
Automated Detection of Hydrothermal Emission Signatures from Multi-Beam Echo Sounder Images Using Deep Learning

Published: November 2022

 Seafloor massive sulfide deposits have attracted attention as a mineral resource, as they contain a wide variety of base, precious, and other valuable critical metals. Previous studies have shown that signatures of hydrothermal activity can be detected by a multi-beam echo sounder (MBES), which would be beneficial for exploring sulfide deposits. Although detecting such signatures from acoustic images is currently performed by skilled humans, automating this process could lead to improved efficiency and cost effectiveness of exploration for the seafloor deposits. Herein, we attempted to establish a method for automated detection of MBES water column anomalies using deep learning models. First, we compared the “Mask R-CNN” and “YOLO-v5” detection model architectures, wherein YOLO-v5 yielded higher F1 scores. We then compared the number of training classes and found that models trained with two classes (signal and noise) exhibited superior performance compared with models trained with only one class (signal). Finally, we examined the number of trainable parameters and obtained the best model performance when the YOLO-v5l model with a large trainable parameters was used in the two-class training process. The best model had a precision of 0.928, a recall of 0.881, and an F1 score of 0.904. Using this method, the detection speed was 20−25 ms per frame, which is faster than the pace at which MBES images can generally be generated. Therefore, our best model can be applied in the field for automatic and real-time exploration of seafloor hydrothermal deposits.

Published: November 2022

Medical image segmentation is essential in medical image analysis since it can provide reliable assistance in computer-aided clinical diagnosis, treatment planning, and intervention. Although deep learning algorithms based on CNNs and Transformers have made notable progress in medical image segmentation, it is still challenging owing to the objects with complex structures, low discrimination and differences between individuals. To alleviate the problems, we propose a novel 3D medical image segmentation network based on Transformers and CNNs combining morphological information and reticular mechanism. Firstly, the morphological constraint stream is designed to learn the prior shape information based on the CNN model for enhancing the interpretability of the ultimate trained model and accelerating the convergence. Secondly, the Reticular Transformer is utilized to obtain multi-scale information based on the Transformer, which can bind the local texture information and underlying semantic information to further acquire the feature maps with sufficient details and receptive field. The experiments demonstrate that our proposed method outperforms many existing segmentation models in terms of the performance in metrics DSC and HD (80.46\% in DSC on the Synapse dataset and 90.83\% in DSC on the ACDC dataset). The code will be released at https://github.com/rocklijun/MCRformer. Our proposed method can not only achieve superior performance compared with most of the current state-of-the-art methods, but also enhance the robustness and interpretability of the model. Furthermore, the proposed morphological constraint stream has the potential to be transferred to other frameworks for different medical image analysis tasks.
