Processing in Memory based on memristors is considered the most effective solution to overcome the Von Neumann bottleneck issue and has become a hot research topic. The execution efficiency of logical computation and in-memory data transmission is crucial for Processing in Memory. This paper presents a design scheme for data transmission and multi-bit multipliers within MAT (a data storage set in MPU) based on the memristive alternating crossbar array structure. Firstly, to improve the data transfer efficiency, we reserve the edge row and column of the array as assistant cells for OR AND (OA) and AND data transmission logic operations to reduce the data transfer steps. Furthermore, we convert the multipliers into multi-bit addition operations via Multiple Input Multiple Output (MIMO) logical operations, which effectively improves the execution efficiency of multipliers. PSpice simulation shows that the proposed data transmission and multi-bit multiplier solution has lower latency and power consumption and higher efficiency and flexibility. [ABSTRACT FROM AUTHOR]

In this research, fully degradable elastomeric sealing materials were developed to enhance the environmental sustainability of oil and gas extraction. The modification of millable polyurethane rubber (MPU) with polyglycolic acid/hydrogenated nitrile butadiene rubber (PGA/HNBR) led to the synthesis of PGA@MPU/HNBR composite materials. The impact of varying monomer quantities on the mechanical properties, degradation behavior, degradation mechanisms, and thermal stability of these materials was investigated. Our findings illustrate that an increasing proportion of HNBR in the PGA@MPU/HNBR composite materials resulted in a decreased degradation rate. Simultaneously, higher HNBR content improved the thermal stability of the materials, while the inclusion of PGA reduced material hardness, rendering the composites more susceptible to swelling. At an HNBR content of 40 phr, MPU at 60 phr, and PGA at 6 phr, the composite material demonstrated the highest retention of mechanical properties at 31.3% following 168 h of hydrolysis at 100 °C. The degradation of the composite materials in 100 °C water primarily resulted from the hydrolysis of MPU's ester groups, with HNBR remaining unaffected. [ABSTRACT FROM AUTHOR]

Monetary policy uncertainty (MPU) not only imposes a great impact on the systematic financial risks of a country but also generates a significant spillover effect on countries having close economic exchanges with the former under the background of global economic integration. With the daily return rates of 64 listed financial companies in China from February 2006 to September 2020 used as the samples, China's systematic financial risks were measured in this research by using long-run marginal expected shortfall (LRMES). On this basis, an FAVAR model with time-varying parameters was constructed to empirically investigate the spillover effect of US MPU on China's systematic financial risks and its main transmission channels. Results showed that within the sample period (February 2006 - September 2020), US MPU generated a significant positive spillover effect on China's systematic financial risks, namely, China's systematic financial risks would be aggravated if the level of US MPU was elevated. From different time intervals, the spillover level was particularly high during global financial crises and global COVID-19 pandemic, indicating that the spillover effect of MPU is nonlinear and closely related to global major sudden risk events. Through the further research, it is found that this effect is mainly transmitted through short-term capital flow, interest rate, and economic uncertainty-induced channels, among which the short-term capital flow is the most important.

The advanced functionality requirements of modern embedded and Internet of Things (IoT) devices - from autonomous vehicles, to city and power-grid management - are driving an ever-increasing software complexity. At the same time, the pervasive internet connections of these systems necessitate the fundamental design of security into these devices. The isolation of complex features from those that are critical through protection domains is an effective means to constrain the scope of faults and security breaches. Common hardware-provided memory facilities to enforce protection domains through memory access control - including MemoryManagement Units (MMUs) usually found in microprocessors, and Memory Protection Units (MPUs) usually found in microcontrollers - must meet the goals of enabling flexible, efficient and dynamic management of memory, and must enable tight bounds on the worst-case execution of critical code. Unfortunately, current system memory management facilities are ill-prepared to handle this challenge: MMUs that use extensive caches to achieve strong average-case performance suffer from debilitating worst-case and even average-case behavior under hefty interference, while MPUs struggle to provide flexible memory management. This paper details MxU, a memory protection and allocation abstraction that integrates temporal specifications into the memory management subsystem, to enable portable code to achieve both predictable, tightlybounded execution and dynamic management across both MMU- and MPU-based systems. We implement MxU in the Composite microkernel, and evaluate its flexibility and predictability over two different architectures: a MPU-based Cortex-M7 microcontroller and a MMU-based Cortex-A9 microprocessor using a suite of modern applications including neural network-based inference, SQLite, and a javascript runtime. For MMU-based systems, MxU reduces application TLB stall by up to 68.0%. For MPU-based systems, MxU enables flexible dynamic memory management often with application overheads of 1%, increasing to 6.1% under significant interference. [ABSTRACT FROM AUTHOR]

The VR / AR market has grown significantly due to the development of virtual reality and augmented reality in the core technology field of the 4th Industrial Revolution. Since VR is basically focused on space and time, and the human brain is very sensitive to temporal events, it is important to make accurate I / O interface technology, one of the virtual reality technologies, not to affect the brain's cognitive ability. VR depends on the technology of the hardware such as the display and the sensor for biometric signal recognition. In this paper, in order to prevent the sensitive brain from affecting the sensor device in consideration of hardware dependency of VR, it is necessary to make various corrections to lower the motion to photon (MTP) to 20m / s or less experiments on the method and filtering were carried out.

The problem of a comparative evaluation of a new technique design under developing the engineering solution and documentation is set. The created fifth-generation mobile power unit (MPU) is compared to the modern machine-process units based on a modern tractor identical in a draught class. The problem is solved through a numerically-analytical method with the parameter synthesis of the multipurpose machine-process units. The problem solution is reduced to detailed calculations in both variants. A nine-field grain zonal rotation rich in green sowing is considered. The analysis has shown that the created MPU with a variable-speed tram drive, two hinged systems unified in load-carrying capacity, and two power-takeoff shafts, will provide unit cost reduction actually caused by the design at a minimum 500 Rub./ha. MPU specifications are as follows: 50 kN class, 220 kW capacity, 9000…9500 kg weight. The essential novelty that distinguishes a new MPU from the standard tractors is provided through the usage of complex multipurpose operations.

ABSTRACT This paper presents a new robust multi-level partition of unity (MPU) method, which constructs an implicit surface from a triangular mesh via the new error metric between the mesh and the implicit surface. The new error metric employs a weighted function of inner points and vertices of a triangle to fit an implicit surface, which can control the approximation error between the surface and vertices of the triangle. Furthermore, it is applied to the MPU method by utilizing the dual graph of a triangular mesh, and the general quadric implicit surface is used for surface representation. Compared with the MPU method, the new method generates fewer subdivision cells with the same approximation error and performs more steadily especially when given triangular mesh with fewer vertices.

Markets have always influenced the central thrust of the semiconductor industry. Beginning in the early eighties, the personal computer (PC) market has been the dominant market influencing the semiconductor industry. Single-chip microprocessors (MPUs) enabled what became the huge PC market, which ultimately overshadowed the earlier minicomputer and mainframe computer markets. The popularity of PCs led to investments in increasingly more powerful MPUs and memory chips of ever-growing capacity. MPUs and DRAMs became the semiconductor industry technology drivers for the data processing needs of the PC. But now, DSP, as opposed to conventional data processing, has become the major technology driver for the semiconductor industry as evidenced by its market growth and the fervour of chip vendors to provide new products based on DSP technology. The increasing need to digitally process analog information signals, like audio and video, is causing a major shift in the semiconductor business. Since DSP is the mathematical manipulation of those digitized information signals, specialized math circuitry is required for efficient signal processing-circuitry that was previously confined to classical DSP chips [ABSTRACT FROM PUBLISHER]

Uric acid (UA) is identified as a danger signal released from dying cells. It precipitates in sodium-rich extracellular fluid and in potassium-rich intracellular fluid as monosodium urate (MSU) and monopotassium urate (MPU), respectively. Here, we examined the structural and functional features of these crystals. In contrast to MPU MSU crystals induced reactive oxygen species production and release of pro-inflammatory cytokines in whole blood ex vivo assays. These results show that the cation of urate crystals determines the response of innate immune cells, indicating that the micromilieu at the site of crystal formation is important for their inflammatory potential.
