In the context of fixed-priority scheduling, feasibility a task set with non-preemptive scheduling does not imply preemptive and vice versa. We use notion preemption threshold, first introduced by Express Logic, in their ThreadX real-time operating system, to develop model that subsumes both fixed priority scheduling. Preemption threshold allows only disable tasks up specified priority. Tasks having priorities higher than are still allowed preempt. With this new model, we show schedulability...

Nowadays, GPUs significantly boost rendering performance. However, the high memory requirements limit their use, especially on low-end mobile platforms. Compression techniques have been widely adopted to reduce consumption but face two primary issues when applied GPUs: 1) low repetition ratio caused by small raw data sizes and concurrency, 2) locality unpredictable behaviors. These limitations result in a compression compressors are devices. This paper introduces gCom , fine-grained...

In order to study the mechanism of biomass tar formation and elimination in a two-stage downdraft gasifier, nascent rice straw pyrolysis evolution properties under homogeneous/heterogeneous decomposition conditions have been investigated constructed lab-scale reactor by varying factors as temperature, concentration reforming agents CO2/H2O/O2, char bed heights. The was produced first stage then decomposed second with different or beds. stage, results showed that yields increased increasing...

Abstract STUDY QUESTION Does the quality of a single transferred blastocyst affect singleton birthweight in frozen-embryo transfer (FET) cycles? SUMMARY ANSWER The poor-quality was associated with lower mean and gestation-adjusted (Z-scores) when compared an excellent-quality during FET cycles. WHAT IS KNOWN ALREADY Embryo is strong predictor IVF success rates. However, very few studies have examined effect embryo on birthweight. DESIGN, SIZE, DURATION This retrospective study involved live...

The localization of invisible and impalpable small pulmonary nodules has become an important concern during surgery, since current widely used techniques for have a number limitations, such as invasive features hookwires microcoils, rapid diffusion after injection indocyanine green (ICG). Lanthanide-based metal-organic frameworks (MOFs) been proven potential fluorescent agents because their prominent luminescent characteristics, including large Stokes shifts, high quantum yields, long decay...

Co-delivery of two or more chemotherapeutic agents via nanocarriers can provide an effective approach to maximize synergistic additive effects. In this work, we developed novel nanodiamond (ND) based nanoparticle co-loading doxorubicin (DOX) and malaridine (MAL) for treatment MCF-7/ADR cells by virtue the good biocompatibility, high drug loading capacity pH-responsive release properties NDs. The combination index (CI) was smallest, 0.17, DOX MAL against cells, when their ratio 5 : 1, showing...

Most preventable deaths after trauma are related to hemorrhage and occur early injury. Timely hemostatic treatment is essential minimize blood loss improve survival. Among the various methods, most economical effective use a agent. A powdered agent can be used for wounds of any shape or depth with high compactness excellent accumulation effect. Herein, we chose natural, hydrophilic polymer poly(γ-glutamic acid) (γ-PGA) form composite microspheres sodium alginate (SA), which show good...

The formation and destruction of pyrolysis tar during the thermal cracking fuel-rich oxidation have been investigated in a constructed test rig. Temperatures 700–1100 °C equivalence ratios (ERs) 0–0.403 were considered, yields gravimetric tar, gas, water, soot taken into account. In inert conditions, was greatly enhanced with temperature increasing. CO CH4 increased almost linearly, H2 exponentially from 700 to 1100 °C; meanwhile, oxygen-containing compounds or substituted 1-ring aromatics...

In this paper, we give a global perspective of multicast capacity and delay analysis in Mobile Ad Hoc Networks (MANETs). Specifically, consider four node mobility models: (1) two-dimensional i.i.d. mobility, (2) hybrid random walk, (3) one-dimensional (4) walk. Two time-scales are investigated paper: (i) fast where is at the same time-scale as data transmissions (ii) slow assumed to occur much slower than transmissions. Given constraint <formula formulatype="inline"...

Energy consumption imposes a significant cost for data centers in providing cloud services. Many studies explore the opportunities to save power by energy-efficient task scheduling based on technique of dynamic voltage and frequency scaling (DVFS). However, most them assume that energy budgets and/or deadline constraints are known advance. But these information can hardly be acquired general computing environments, such as computing, job rejections caused restricted intolerable guarantee...

The energy consumption in heterogeneous computing systems (HCS) has attracted a great deal of attention both scientific and commercial fields due to operating environmental concerns. Based on the technique dynamic voltage frequency scaling (DVFS), many studies have investigated developed efficient task scheduling algorithms for reduction. However, most them provide only one refined each perform slack reclamation. Moreover, total energy-saving is accumulated by individual local minimum with...

Patients with major depressive disorders (MDD) exhibit social dysfunction, as illustrated by the lower acceptance rate of unfair proposals in Ultimatum Game (UG) among patients MDD compared a control group. However, underlying mechanisms remain largely unknown. In this study, we explored whether had altered perceptions fairness or perception-behavior linkages group, using multilevel moderated mediation framework. Sixty-eight unmedicated and 55 members group were recruited. Using generalized...

Accurate photovoltaic (PV) power forecasting is critical for integrating renewable energy sources into the grid, optimizing real-time management, and ensuring reliability amidst increasing demand. However, existing models often struggle with effectively capturing complex relationships between target variables covariates, as well interactions temporal dynamics multivariate data, leading to suboptimal accuracy. To address these challenges, we propose a novel model architecture that leverages...

Intrusion detection in a Wireless Sensor Network (WSN) is of significant importance many applications to detect malicious or unexpected intruder(s). The intruder can be an enemy battlefield, unusual environmental change chemical industry etc. With uniform distribution, the probability same for any point WSN. However, some may require different degrees at locations deployment area. Gaussian distributed WSNs (i.e., normal distribution) provide differentiated capabilities and are widely...

Object tracking is one of the fundamental applications in Wireless Sensor Networks (WSNs). To detect and track appearance movement malicious object(s), a number sensors are usually deployed randomly area interest specially for hostile application scenarios. Following random deployment strategy, resulting WSNs conform to Poisson or Gaussian distribution, depending on specific approach. It significant importance investigate compare performance distributed object tracking, since sensor plays an...
