Механизм терапевтического действия мультипотентных мезенхимных стволовых клеток (ММСК) на облученный организм в последнее время вызывает повышенный интерес исследователей. В качестве активного участника паракринного механизма реализации этого эффекта предлагают рассматривать внеклеточные везикулы, секретируемые практически всеми клетками живого организма. Цель работы: выделить и охарактеризовать внеклеточные везикулы, продуцируемые стволовыми клетками различной природы. Материалы и методы. Суспензии внеклеточных везикул, выделенных по модифицированному протоколу дифференциального центрифугирования из культуральных жидкостей от культур ММСК костного мозга человека 2-го пассажа и ММСК жировой ткани крысы 4-го пассажа, были проанализированы методом просвечивающей электронной микроскопии и методом анализа траекторий наночастиц. Результаты. Исследование показало наличие в обоих образцах микрочастиц размерами до и около 100 нм, однако процентное содержание частиц разных размеров в суспензии различалось для двух анализируемых типов клеток. Заключение. Полученные результаты могут свидетельствовать о специфике секреции, обусловленной клеточным типом.A mechanism of the therapeutic effect of multipotent mesenchymal stem cells (MMSC) on irradiated body has recently arisen much interest of researchers. Extracellular vesicles (EVs) secreted by almost all cells of a living organism were suggested to actively contribute to the paracrine mechanism of this effect. The aim of the study was isolation and characterization of extracellular vesicles produced by various types of stem cells. Materials and methods. Suspensions of EVs were isolated from culture media of passage 2 human bone marrow-derived MMSC and passage 4 rat adipose tissue-derived MMSC using a modified protocol of differential centrifugation and then studied using transmission electron microscopy and nanoparticle tracking analysis.

Published: December 2020

AbstrakArtikel ini memaparkan identitas komunitas penutur bahasa (kreol) yang direpresentasikan di dalam Alkitab terjemahan Melayu-Kupang. Penutur bahasa, secara implisit, cenderung menunjukkan kepercayaanya, nilai yang dianut, serta kebutuhan melalui wacana dalam komunikasi. Hal tersebut terwujud melalui interaksi terdahulu hingga saat kini. ‘Index of importance’ atau kategori kepentingan dari suatu komunitas dirasakan oleh penuturnya melalui ciri linguistik kebahasaan karena bahasa membentuk tatanan sosial dan interaksi suatu relasi. Setiap penutur bahasa terasosiasi dengan penanda leksikal tertentu dan penanda tersebut berganti seiring perubahan konteks komunikasi yang terjadi. Identitas lokal yang digambarkan Alkitab Terjemahan Bahasa (kreol) Kupang berdasarkan prinsip penerjemahan kebermaknaan, dan mengintegrasikan budaya dan tradisi komunitas penutur kreol MelayuKupang. Inti analisis mencakup indeks perubahan dalam status sosial; nama baru, panggilan sapaan dalam relasi horisontal dan vertikal, kesopanan bahasa, kata leksikal, dan konteks situasi. Disimpulkan bahwa komunitas penutur kreol Melayu Kupang yang digambarkan dalam Alkitab terjemahan tersebut belum seutuhnya tercermin berdasarkan keadaan dan tradisi sesungguhnya: kategori rujukan dalam interaksi sosial dengan penggunaan ‘register’ yang berbeda; pilihan diksi untuk wacana bervariasi; tingkat kesopanan; relasi vertikal dan horisontal. Revisi pada terjemahan Alkitab KM sangat diperlukan karena merefleksikan gambaran komunitas Melayu Kupang kepada publik. Kata-kata kunci: konstruksi interaksi, status sosial, identitas setempat AbstractThis present paper discusses the local identity represented in the Kupang-Malay creole translated Bible. Language speakers implicitly reflect their beliefs, values, and needs through their language and discourse during communication. They were shared through past and present interaction. The speakers index of importance or category of interest is experienced by the speakers and manifested into linguistics features. Within this social construct, each speaker is associated with specific lexical markers in different contexts. This paper discusses how Kupang-Malay reflects local identity. The analysis covers the index of change, terms of address in the vertical and horizontal direction. The primary data is Kupang Malay Bible. The results of the analysis show that overall the Kupang-Malay community has not represented well in the Bible: in terms of the category of reference they commonly use, registers, level of politeness in language usage across ages, vertical and horizontal relationships. A room for improvement on the Bible translation is needed to represent the Kupang-Malay community better.Keywords: interactional construct, social status, local identity

Authors: De Souza Rafael Navarenho , Guazzelli Marcilei A. , Gimenez Salvador P. 
Published: December 2020

This paper presents an experimental comparative study of the Total Ionizing Dose (TID) effects between the Metal-Oxide-Semiconductor (MOS) Field Effect Transistors (MOSFET) manufactured with the Wave (S gate geometry) and the standard layout (CnM). Because of the special geometric characteristic of the gate, drain and source regions of the Wave MOSFET (WnM), this innovative layout proposal for transistors is able to mitigate the TID effects in order to implement in analog integrated circuits (IC) for space and medical applications without causing any additional cost to the Complementary MOS (CMOS) manufacturing process.

Authors: Toledo Pedro , Klimach Hamilton , Cordova David , Bampi Sergio , Fabris Eric 
Published: December 2020

In this paper a self-biased current reference based on Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) Zero Temperature Coefficient (ZTC) condition is proposed. It can be implemented in any Complementary Metal-Oxide-Semiconductor (CMOS) fabrication process and provides another alternative to design current references. In order to support the circuit design, ZTC condition is analyzed using a MOSFET model that is continuous from weak to strong inversion, showing that this condition always occurs from moderate to strong inversion in any CMOS process. The proposed topology was designed in a 180 nm process, operates with a supply voltage from 1.4V to 1.8 V and occupies around 0.010mm2 of silicon area. From circuit simulations our reference showed a temperature coefficient (TC) of 15 ppm/oC from -40 to +85oC, and a fabrication process sensitivity of σ/μ = 4.5% for the current reference, including average process and local mismatch variability analysis. The simulated power supply sensitivity is estimated around 1%/V.

A Novel Built-in Self Calibration Technique to Minimize Capacitor Mismatch for 12-bit 32MS/s SAR ADC
Authors: Jung Inseok , Kim Kyung Ki , Kim Yong-Bin 
Published: December 2020

This paper proposes a novel Built-in Self Calibration (BISC) technique for a 12-bit 32MS/s successive approximation register (SAR) analog-to-digital converter (ADC) using a single input to reduce the capacitor mismatch of the digital-to-analog converter (DAC) and to compensate the comparator input offset voltage. The proposed self-calibration scheme optimize the mismatch of the DAC by changing additional auxiliary capacitor array during calibration mode. In addition, in order to minimize the offset voltage of the comparator in the SAR ADC, a simplified voltage amplifier is proposed. The controller for the proposed algorithm operates as foreground operation to achieve low power consumption during operation. Compared to the converters that use the conventional procedure, INL and DNL are reduced by about 47% and 52%, respectively. The prototype was designed using 130nm single poly 6 metal standard CMOS technology. The ADC achieves a SNDR of 65.6 dB and consumes 4.62 mW. The ADC core occupies an active area of only 240μmÍ 298 μm using 1.2V supply and the sampling rate of 50 MS/s.
A Defects Simulator for Robustness Analysis of QCA Circuits
Authors: Reis Dayane Alfenas , Torres Frank Sill 
Published: December 2020

Although QCA (Quantum-dot Cellular Automata) is a promising nanotechnology to replace CMOS (Complementary Metal-Oxide-Semiconductor), it has several known reliability problems. Consequently, the design of robust QCA structures is a mandatory step towards the consolidation of this new technology. This paper presents a novel methodology for error analysis of QCA structures based on deterministic and random insertion of possible defects to either the cells and to the phase shifts of the clocking circuit. Further features presented are an evaluation of structures robustness and identification of the design elements most susceptible to the defects. Simulation results obtained from the implemented QCA Defects Simulator indicate the feasibility of the proposed error exploration methodology, also revealing starting-points for robustness improvements of known QCA structures.

Published: December 2020

Focal-plane processing is the target of many studies due to its potential for enhancing the speed of the vision system flow. With focal-plane processing it is possible to perform parallel processing throughout the entire matrix. In order to alleviate A/D conversion and transmission constraints, analog image compression is implemented at the focal plane, thereby reducing the amount of data to be transmitted and the bandwidth requirements. The ADC is performed at the focal plane as well, after the compression operation whose realization is based on differential pulse-code modulation (DPCM), linear transform and vector quantization (VQ) applied on every 4 × 4 pixel block using current-mode circuits. This paper presents experimental results obtained from a second-generation version of the image sensor. Among these results we can point out the presentation of different captured images and the modeling of errors that were identified during the experimental tests. Since the source of these errors is the DPCM stage, the modeling concerns the bits that refer to the mean block luminance results. The error modeling procedure was developed considering the relationship between the pixel integration period and the DPCM quantizer threshold values. The main contributions of the second-generation chip in comparison to the previous realization are: increase of the vector quantizer complexity, number of bits per pixel, pixel matrix size, and the use of cascode current mirrors in the linear transform matrix. The image sensor advanced in this paper was fabricated in a standard 180 nm CMOS process.

This work presents a CMOS four quadrant analog multiplier architecture for application as the synapse element in analog cellular neural networks. For this reason, the circuit has voltage-mode inputs and a current-mode output and the chief design targets are compactness and low energy consumption. A signal application method is proposed that avoids voltage reference generators, which contributes to reduce sensitivity to supply voltage variation. Performance analysis through simulation has been accomplished for a design in CMOS 130 nm technology with 163 µm2 total active area. The circuit features ±50 mV input voltage range, 86 µW static power and ‑28.4 dB maximum total harmonic distortion. A simple technique for manual calibration is also presented.

Hardware support in a middleware for distributed and real-time embedded applications

Published: December 2020

One of the main challenges in the development of tools and methodologies for a multiprocessor realtime embedded system is to reuse already developed software, but at the same time obtaining low memory footprint, low energy consumption, and minimal area, obviously addressing the real-time constraints. This work aims to face these problems at the middleware level.We show that adaptations in the platform architecture, for instance exploring hardware implementations of middleware services, such as task scheduling and communication, can drive better gains in application requirements like energy and performance, which are essential for embedded applications. This approach is coupled with a high flexibility in choosing either a hardware or a software implementation, because services are encapsulated into objects and the application development and the design space exploration at middleware level can be performed independently from each other, in a fully transparent way. Furthermore, the use of the object-oriented approach reduces time-to-market and development costs.
Mapping of Massive Data Processing Systems to FPGA Computers Based on Temporal Partitioning and Design Space Exploration

Published: December 2020

High parallelism degree is fundamental for high speed massive data processing systems. Modern FPGA devices can provide such parallelism plus flexibility. However, these devices are still limited by their logic block size, memory size, memory bandwidth and configuration time. Temporal partitioning techniques can be a solution for such problems when FPGAs are used to implement large systems. In this case, the system is split into partitions (called contexts), multiplexed in a FPGA, by using reconfiguration techniques. This approach can increase the effective area for system implementation, allowing increase of parallelism in each task that composes the application. However, the necessary reconfiguration time between contexts can cause performance decrease. A possible solution for this is an intensive parallelism exploration of massive data application to compensate for this overhead and improve global performance. This is true for modern FPGA with relatively high reconfiguration speed. In this work, A reconfigurable computer platform and design space exploration techniques are proposed for mapping of such massive data applications, as image processing, in FPGA devices, depending on the application task scheduling. A library with different hardware implementation for a different parallelism degree is used for better adjustment of space/time for each task. Experiments demonstrate the efficiency of this approach when compared to the optimal mapping reached by exhaustive timing search in the complete design space exploration. A design flow is shown based on library components that implements typical tasks used in the domain of applications.
