STT-MRAM Technology For Energy-Efficient Cryogenic Memory Applications

This work explores non-volatile (NV) embedded memories implemented by spin-transfer torque magnetic random access memories (STT-MRAMs). Our designs are based on state-of-the-art perpendicular magnetic tunnel junctions (MTJs) along with a commercial 65 nm planar CMOS Bulk technology node, both operating at the liquid nitrogen temperature, 77 K. We evaluate the impact of cooling down to 77 K of the STT-MRAMs based on single- and double-barrier MTJ (SMTJ and DMTJ), and DMTJ with the relaxed non-volatility. All NV designs were benchmarked against the six-transistor SRAM (6T-SRAM) baseline. Simulation analysis relies on a 512 kB cache memory operating at 77 K. Overall, results show that the implementation of STT-MRAMs with DMTJ devices, and in particular when using the non-volatility approach by reducing the cross-section area, excel in terms of energy consumption, leading to energy savings for write/read access of about 35%/54%. This saving is obtained while also dissipating less leakage power and requiring a smaller bitcell footprint. Moreover, it presents reduced write latency overhead (as much as 1.9× lower), at the expense of increased read latency and reduced sensing margins of about 1.8× and 88%, respectively. The results suggest that STT-MRAM technology can be a solid alternative for energy-efficient cryogenic memory applications.
Helicobacter pylori and Epstein–Barr Virus Co-Infection in Gastric Disease: What Is the Correlation with p53 Mutation, Genes Methylation and Microsatellite Instability in a Cohort of Sicilian Population?

Genetic predisposition, environmental factors, and infectious agents interact in the development of gastric diseases. Helicobacter pylori (Hp) and Epstein–Barr virus (EBV) infection has recently been shown to be correlated with these diseases. A cross-sectional study was performed on 100 hospitalized Italian patients with and without gastric diseases. The patients were stratified into four groups. Significant methylation status differences among CDH1, DAPK, COX2, hMLH1 and CDKN2A were observed for coinfected (Hp-EBV group) patients; particularly, a significant presence of COX2 (p = 0.0179) was observed. For microsatellite instability, minor stability was described in the Hp-HBV group (69.23%, p = 0.0456). Finally, for p53 mutation in the EBV group, exon 6 was, significantly, most frequent in comparison to others (p = 0.0124), and in the Hp-EBV group exon 8 was, significantly, most frequent in comparison to others (p < 0.0001). A significant positive relationship was found between patients with infection (Hp, EBV or both) and p53 mutation (rho = 0.383, p = 0.0001), methylation status (rho = 0.432, p < 0.0001) and microsatellite instability (rho = 0.285, p = 0.004). Finally, we observed among infection and methylation status, microsatellite instability, and p53 mutation a significant positive relationship only between infection and methylation status (OR = 3.78, p = 0.0075) and infection and p53 mutation (OR = 6.21, p = 0.0082). According to our analysis, gastric disease in the Sicilian population has different pathways depending on the presence of various factors, including infectious agents such as Hp and EBV and genetic factors of the subject.
Efficient and Robust KPI Outlier Detection for Large-Scale Datacenters

To ensure the performance of large-scale datacenters, operators need to monitor up to tens of millions of various-type KPIs, e.g., CPU utilization, memory utilization. For each KPI, it is crucial but challenging to detect outliers that deviate from its historical patterns or the patterns of other KPIs in the same period. In this work, we propose OutSpot, an unsupervised outlier detection framework that integrates hierarchical agglomerative clustering (HAC) with conditional variational autoencoder (CVAE), which significantly improves computational efficiency and comprehensively learns the above two patterns. Additionally, two simple yet effective techniques, soft threshold and median filter, are applied to precisely determine outlier KPIs. Using two real-world datasets collected from the datacenters owned by a top-tier global short video service provider and a top-tier domestic operator,respectively. It demonstrates that OutSpot achieves the best F1 score of 0.95 and 0.91, AUC of 0.99 and 0.99 on the two datasets, significantly outperforming seven baseline outlier detection methods.
7Li NMR studies on the triangular lattice system LiCrO2

We report $^{7}\mathrm{Li}$ NMR, magnetic susceptibility, and heat capacity measurements on the triangular lattice Heisenberg antiferromagnet compound $\mathrm{Li}\mathrm{Cr}{\mathrm{O}}_{2}$. We find that in contrast to $\mathrm{Na}\mathrm{Cr}{\mathrm{O}}_{2}$, magnetic properties of $\mathrm{Li}\mathrm{Cr}{\mathrm{O}}_{2}$ have a more pronounced three dimensional character with sharp anomalies in the temperature variation of the $^{7}\mathrm{Li}$ NMR intensity and the NMR spin-lattice relaxation rate $1∕{T}_{1}$. From heat capacity measurements we find that the total entropy related to the magnetic transition is in agreement with expectations. However, we find a significant contribution to the magnetic entropy in the range from the ordering temperature ${T}_{N}$ to nearly $4{T}_{N}$. This suggests the existence of magnetic correlations at temperatures well above ${T}_{N}$ which might be due to the frustrated nature of the system. Based on the temperature dependence of $1∕{T}_{1}$, we discuss the possible occurrence of a Kosterlitz-Thouless-Berezinskii (KTB) transition taking place at ${T}_{\mathrm{KTB}}=54\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ in $\mathrm{Li}\mathrm{Cr}{\mathrm{O}}_{2}$. Heat capacity data at low temperatures $(T⪡{T}_{N})$ exhibited a ${T}^{3}$ dependence and the ratio of interlayer to intralayer coupling constants, ${J}_{\ensuremath{\perp}}∕J$ in $\mathrm{Li}\mathrm{Cr}{\mathrm{O}}_{2}$ was found to be $\ensuremath{\sim}{10}^{\ensuremath{-}3}$. Lithium depletion has no significant effect on the magnetic properties and the behavior of ${\mathrm{Li}}_{0.5}\mathrm{Cr}{\mathrm{O}}_{2}$ is nearly unchanged from that of $\mathrm{Li}\mathrm{Cr}{\mathrm{O}}_{2}$.
An Assessment of Unconventional Monetary Policy During COVID-19 Pandemic in India

We employ event study methodology to analyze the impact of unprecedented unconventional monetary policy (UMP) measures employed by the Reserve Bank of India to fortify monetary transmission mechanism and to restore financial stability. We find that the UMP announcements result in a decline in bond yields and yield spread as well as increase in market capitalization and sectoral portfolio of stock returns. Evaluating the relative efficacy of UMP measures, we find that targeted long-term repo operation announcements are more effective in easing bond yields than mere long-term repo operations. Our findings provide beneficial inference for day-traders and investors as asset prices increase significantly and durable goods producing stock returns found to be higher than those of non-durable goods. The lessons that can be drawn for the emerging market economy central banks, who do not have enough space to conduct conventional monetary policy and even when they do not face zero lower bound interest rate, they still can employ UMP tools to directly influence banks cost of funds, and long-term bond yields and interest rates, and in turn, portfolio of stock returns and investments to stimulate aggregate demand.

On conditional diffusion processes

Synopsis If Xt is the diffusion process associated with a second-order uniformly elliptic operator L in divergence form, then without assuming smoothness in L we prove that for each x and y in ℝd, where p is the fundamental solution to the heat equation associated with L. This allows one to control p when bounded drift terms are added to L; and also allows one to do Stratonovich integration with respect to the process conditioned to start at any point; previous work only dealt with quasi-every starting point.
Residual-Based False Data Injection Attacks Against Multi-Sensor Estimation Systems

This paper investigates the security issue of multi-sensor remote estimation systems. An optimal stealthy false data injection (FDI) attack scheme based on historical and current residuals, which only tampers with the measurement residuals of partial sensors due to limited attack resources, is proposed to maximally degrade system estimation performance. The attack stealthiness condition is given, and then the estimation error covariance in compromised state is derived to quantify the system performance under attack. The optimal attack strategy is obtained by solving several convex optimization problems which maximize the trace of the compromised estimation error covariance subject to the stealthiness condition. Moreover, due to the constraint of attack resources, the selection principle of the attacked sensor is provided to determine which sensor is attacked so as to hold the most impact on system performance. Finally, simulation results are presented to verify the theoretical analysis.
Overview of Diagnostic Methods, Disease Prevalence and Transmission of Mpox (Formerly Monkeypox) in Humans and Animal Reservoirs

Mpox—formerly monkeypox—is a re-emerging zoonotic virus disease, with large numbers of human cases reported during multi-country outbreaks in 2022. The close similarities in clinical symptoms that Mpox shares with many orthopoxvirus (OPXV) diseases make its diagnosis challenging, requiring laboratory testing for confirmation. This review focuses on the diagnostic methods used for Mpox detection in naturally infected humans and animal reservoirs, disease prevalence and transmission, clinical symptoms and signs, and currently known host ranges. Using specific search terms, up to 2 September 2022, we identified 104 relevant original research articles and case reports from NCBI-PubMed and Google Scholar databases for inclusion in the study. Our analyses observed that molecular identification techniques are overwhelmingly being used in current diagnoses, especially real-time PCR (3982/7059 cases; n = 41 studies) and conventional PCR (430/1830 cases; n = 30 studies) approaches being most-frequently-used to diagnose Mpox cases in humans. Additionally, detection of Mpox genomes, using qPCR and/or conventional PCR coupled to genome sequencing methods, offered both reliable detection and epidemiological analyses of evolving Mpox strains; identified the emergence and transmission of a novel clade ‘hMPXV-1A’ lineage B.1 during 2022 outbreaks globally. While a few current serologic assays, such as ELISA, reported on the detection of OPXV- and Mpox-specific IgG (891/2801 cases; n = 17 studies) and IgM antibodies (241/2688 cases; n = 11 studies), hemagglutination inhibition (HI) detected Mpox antibodies in human samples (88/430 cases; n = 6 studies), most other serologic and immunographic assays used were OPXV-specific. Interestingly, virus isolation (228/1259 cases; n = 24 studies), electron microscopy (216/1226 cases; n = 18 studies), and immunohistochemistry (28/40; n = 7 studies) remain useful methods of Mpox detection in humans in select instances using clinical and tissue samples. In animals, OPXV- and Mpox-DNA and antibodies were detected in various species of nonhuman primates, rodents, shrews, opossums, a dog, and a pig. With evolving transmission dynamics of Mpox, information on reliable and rapid detection methods and clinical symptoms of disease is critical for disease management.
Repeat sun-synchronous orbit design method based on Q value selection

Repeat sun-synchronous orbit is one of the most important orbits for earth observation missions,because the orbit can satisfy the requirements of illumination and temporal resolution.Q value is the connection between sun-synchronous orbit and repeat orbit,so Q value plays an important role in repeat sun-synchronous orbit design.In this paper,the characteristics of sun-synchronous orbit and repeat orbit are analyzed,and the relationship of Q value and repeat sun-synchronous orbit is established.With the analysis of repeat orbit characteristics,a Q value design method of repeat sun-synchronous orbit is derived,and an optimal orbit is selected using the method.The selected orbit shows that the orbital altitude is 502.59 km,repeat period is 21 days and mean revisit period is 5 days,which is an optimal repeat sun-synchronous orbit for the revisit characteristic within the range from 500 km to 510 km.It concludes that this method finds the key points of repeat sun-synchronous orbit design in theory,and provides a credible and easy method for complex orbit design tasks.

The aim is todescribe boundary behavior of holomorphic discs in convex nite typedomains in the complex Euclidean space in term of a special local neigh-borhood system at a boundary point. 1. IntroductionWe will describe the boundary behavior of holomorphic discs in a domain(connected open set) in C n in terms of a certain local neighborhood systemat a boundary point. This research has its origin in author’s thesis ([5]) forstrongly pseudoconvex domains in almost complex manifolds. An aim of [5] wasto study a convergence of the scaling sequence in almost complex manifolds.In order to get the convergence, it needs to consider a special neighborhoodsystem at a strongly pseudoconvex boundary point which is invariant underthe non-isotropic dilation. Let be a domain in C n which has the hyperplanefz2C n : Rez 1 = 0gas a tangent plane at the strongly pseudonvex boundarypoint 0 2@. Then we consider the local neighborhood system fQ(0;) : >0gof 0 whereQ(0;) = fz= (z
The Influence of Promotion and Service Quality on Consumer Purchase Decisions

Obesity, the Adipose Organ and Cancer in Humans: Association or Causation?

Epidemiological observations, experimental studies and clinical data show that obesity is associated with a higher risk of developing different types of cancer; however, proof of a cause–effect relationship that meets the causality criteria is still lacking. Several data suggest that the adipose organ could be the protagonist in this crosstalk. In particular, the adipose tissue (AT) alterations occurring in obesity parallel some tumour behaviours, such as their theoretically unlimited expandability, infiltration capacity, angiogenesis regulation, local and systemic inflammation and changes to the immunometabolism and secretome. Moreover, AT and cancer share similar morpho-functional units which regulate tissue expansion: the adiponiche and tumour-niche, respectively. Through direct and indirect interactions involving different cellular types and molecular mechanisms, the obesity-altered adiponiche contributes to cancer development, progression, metastasis and chemoresistance. Moreover, modifications to the gut microbiome and circadian rhythm disruption also play important roles. Clinical studies clearly demonstrate that weight loss is associated with a decreased risk of developing obesity-related cancers, matching the reverse-causality criteria and providing a causality correlation between the two variables. Here, we provide an overview of the methodological, epidemiological and pathophysiological aspects, with a special focus on clinical implications for cancer risk and prognosis and potential therapeutic interventions.
Stress analysis of a beveled diamond anvil

A finite element stress analysis has been performed on a brilliant cut high‐pressure diamond anvil. The analysis includes the presence of a metal gasket. A perfectly cohesive interface is assumed to exist between the diamond and metal. Different configurations of the anvil face were studied. The stress distribution resulting from various beveled angles has been analyzed. It has been found that for a flat anvil, with a center normal pressure of about 210 kbar, an octahedral shearing stress of about 90 kbar is present near the center and monotonically increases radially to about 208 kbar along the outer edge. When the anvil surface is beveled, the octahedral shearing stress at the outer corner decreases significantly. The optimum beveled angle necessary to minimize these stresses seems to lie in the neighborhood of 15°. The assumptions made and other stress considerations are discussed.
Microbial and Qualitative Traits of Quinoa and Amaranth Seeds from Experimental Fields in Southern Italy

Quinoa and amaranth are of special interest since they are increasingly used for the development of new bakery products with enhanced nutritional value. The aim of the study was to evaluate the agronomic, microbiological, and nutritional characteristics of quinoa and amaranth seeds grown in Southern Italy. For this reason, quinoa Titicaca and three amaranth accessions (5, 12, and 14) were cultivated in different experimental fields in the Campania Region and analyzed for the cultivation aspects, chemical composition, and microbiological quality of the seeds. All seeds showed a good adaptability to cultivation in the experimental areas of the Mediterranean basin. Quinoa seeds were characterized by their higher protein, fat, and ash content than the amaranth seeds, which were characterized by their higher value in dietary fiber. All seeds, regardless of the geographical area of production, were contaminated with yeasts, moulds, and spore-forming bacteria, mainly Bacillus cereus, B. licheniformis, B. safensis and B. subtilis, as identified by 16S rRNA sequencing analysis. So, the detection of Bacillus spp. must be strongly monitored, as quinoa and amaranth seeds could be used in bread production, where they can cause ropiness, resulting in great economic losses for the industries.
California’s GHG Cap-and-Trade Program and the Equity of Air Toxic Releases

Carbon trading faces pushback over concerns of increasing copollutant exposure for minorities. Combining federal and state data I evaluate three questions concerning the distribution of hazardous air pollutants after implementation of California’s greenhouse gas cap-and-trade program. Did air toxic releases from facilities covered by the GHG program upwind of minorities disproportionately increase? Did minority communities suffer a disproportionate increase in cumulative exposure from covered facilities? Did minorities overall suffer higher exposure to air toxics from all sources relative to a counterfactual no-cap-and-trade scenario? Results suggest that covered facilities upwind of minorities did not have higher releases, and minority communities experienced a relative reduction in cumulative exposure from them. Under all policy scenarios minorities have a less desirable exposure distribution than whites. However, both demographic groups have a better air toxic exposure distribution with the cap-and-trade program than in a counterfactual without.
Modeling and Model Verification of the Stress-Strain State of Reinforced Polymer Concrete

This article considers the prospects of the application of building structures made of polymer concrete composites on the basis of strength analysis. The issues of application and structure of polymer-concrete mixtures are considered. Features of the stress-strain state of normal sections of polymer concrete beams are revealed. The dependence between the stresses and relative deformations of rubber polymer concretes and beams containing reinforcement frame and fiber reinforcement has been determined. The main direction of the study was the choice of ways to increase the strength characteristics of concrete with the addition of a polymer base and to increase the reliability of structures in general. The paper presents the results of experimental and mathematical studies of the stress-strain state and strength, as well as deflections of reinforced rubber-polymer beams. The peculiarities of fracture of reinforced rubber-polymer beams along their sections have been revealed according to the results of the experiment. The peculiarities of fracture formation of reinforced rubber-polymer beams have also been revealed. The conducted work has shown that the share of longitudinal reinforcement and the height of the fibrous reinforcement zone are the main factors. These reasons determine the characteristics of the strength of the beams and their resistance to destructive influences. The importance and scientific novelty of the work are the identified features of the stress-strain state of normal sections of rubber-concrete beams, namely, it has been established that the ultimate strength in axial compression and tension, deformations corresponding to the ultimate strength for rubber concrete exceed similar parameters for cement concrete 2.5–6.5 times. In the case of the addition of fiber reinforcement, this increase becomes, respectively, 3.0–7.5 times.
Manipulation of Motion Parallax Gain Distorts Perceived Distance and Object Depth in Virtual Reality

Virtual reality (VR) is distinguished by the rich, multimodal, im-mersive sensory information and affordances provided to the user. However, when moving about an immersive virtual world the vi-sual display often conflicts with other sensory cues due to design, the nature of the simulation, or to system limitations (for example impoverished vestibular motion cues during acceleration in racing games). Given that conflicts between sensory cues have been as-sociated with disorientation or discomfort, and theoretically could distort spatial perception, it is important that we understand how and when they are manifested in the user experience. To this end, this set of experiments investigates the impact of mismatch between physical and virtual motion parallax on the per-ception of the depth of an apparently perpendicular dihedral angle (a fold) and its distance. We applied gain distortions between visual and kinesthetic head motion during lateral sway movements and measured the effect of gain on depth, distance and lateral space compression. We found that under monocular viewing, observers made smaller object depth and distance settings especially when the gain was greater than 1. Estimates of target distance declined with increasing gain under monocular viewing. Similarly, mean set depth decreased with increasing gain under monocular viewing, except at 6.0 m. The effect of gain was minimal when observers viewed the stimulus binocularly. Further, binocular viewing (stereopsis) improved the precision but not necessarily the accuracy of gain perception. Overall, the lateral compression of space was similar in the stereoscopic and monocular test conditions. Taken together, our results show that the use of large presentation distances (at 6 m) combined with binocular cues to depth and distance enhanced humans' tolerance to visual and kinesthetic mismatch.
