EEG mapping using the personal computer

An approach for brain electrical activity mapping using a personal computer has been investigated to enhance the visibility of the EECs. An automatic procedure from data acquisition to the final mapping has been developed for on-line or off-line data processing, in which a table-look-up technique has been introduced to eliminate redundant processing. The power spectra in different EEC frequency bands for four electrodes are coded into 15 colors and mapped on a color monitor. The data correspondings to the areas between electrodes are interpolated by the surface spline method. The mapping speed and smoothness has been optimized. An experiment has been clone for 6 subjects, including a normal person, and five patients with different medical histories. The results are mostly in agreement with the pathological reports and can detect sonic underlying brain dysfunctions which EEC specialists may fail to see. This method may offer an important tool for clinical diagnosis and for future brain study

Advances in the Treatment of Invasive Fungal Disease

With over 300 million severe cases and 1.5 million deaths annually, invasive fungal diseases (IFDs) are a major medical burden and source of global morbidity and mortality. The World Health Organization (WHO) recently released the first-ever fungal priority pathogens list including 19 fungal pathogens, considering the perceived public health importance. Most of the pathogenic fungi are opportunistic and cause diseases in patients under immunocompromised conditions such as HIV infection, cancer, chemotherapy, transplantation, and immune suppressive drug therapy. Worryingly, the morbidity and mortality caused by IFDs are continuously on the rise due to the limited available antifungal therapies, the emergence of drug resistance, and the increase of population that is vulnerable to IFDs. Moreover, the COVID-19 pandemic worsened IFDs as a globe health threat as it predisposes the patients to secondary life-threatening fungi. In this mini-review, we provide a perspective on the advances and strategies for combating IFDs with antifungal therapies

The Effect Of Humble Leader Behavior, Leader Expertise, And Organizational Identification On Employee Turnover Intention

As a bottom-up leadership style, humble leadership has attracted increasing attention from scholars in recent years. But its effectiveness and mechanism still lack rigorous empirical study. In this study, we investigate the mechanism and boundary condition by which humble leader behavior exerts influence on followers’ turnover intention. Two-wave data collected from 249 scientific and technological personnel in China supported our hypothesized model. We found that humble leader behavior is significantly negatively related to follower turnover intention. The relationship is further partially mediated by organizational identification, and moderated by leader expertise. Implications for theory, practice and future research are discussed.

One size does not fit all : accelerating OLAP workloads with GPUs

GPU has been considered as one of the next-generation platforms for real-time query processing databases. In this paper we empirically demonstrate that the representative GPU databases [e.g., OmniSci (Open Source Analytical Database & SQL Engine,, 2019)] may be slower than the representative in-memory databases [e.g., Hyper (Neumann and Leis, IEEE Data Eng Bull 37(1):3-11, 2014)] with typical OLAP workloads (with Star Schema Benchmark) even if the actual dataset size of each query can completely fit in GPU memory. Therefore, we argue that GPU database designs should not be one-size-fits-all; a general-purpose GPU database engine may not be well-suited for OLAP workloads without careful designed GPU memory assignment and GPU computing locality. In order to achieve better performance for GPU OLAP, we need to re-organize OLAP operators and re-optimize OLAP model. In particular, we propose the 3-layer OLAP model to match the heterogeneous computing platforms. The core idea is to maximize data and computing locality to specified hardware. We design the vector grouping algorithm for data-intensive workload which is proved to be assigned to CPU platform adaptive. We design the TOP-DOWN query plan tree strategy to guarantee the optimal operation in final stage and pushing the respective optimizations to the lower layers to make global optimization gains. With this strategy, we design the 3-stage processing model (OLAP acceleration engine) for hybrid CPU-GPU platform, where the computing-intensive star-join stage is accelerated by GPU, and the data-intensive grouping & aggregation stage is accelerated by CPU. This design maximizes the locality of different workloads and simplifies the GPU acceleration implementation. Our experimental results show that with vector grouping and GPU accelerated star-join implementation, the OLAP acceleration engine runs 1.9x, 3.05x and 3.92x faster than Hyper, OmniSci GPU and OmniSci CPU in SSB evaluation with dataset of SF = 100.Peer reviewe

Spontaneous Deformation of an AdS Spherical Black Hole

In this study, we investigate the real-time dynamics during the spontaneous deformation of an unstable spherical black hole in asymptotically anti-de Sitter (AdS) spacetime. For the initial value, the static solutions with spherical symmetry are obtained numerically, revealing the presence of a spinodal region in the phase diagram. From the linear stability analysis, we find that only the central part of such a thermodynamically unstable spinodal region leads to the emergence of a type of axial instability. To trigger the dynamical instability, an axial perturbation is imposed on the scalar field. As a result, by the fully nonlinear dynamical simulation, the spherical symmetry of the gravitational system is broken spontaneously, leading to the formation of an axisymmetric black hole.Comment: 16 pages, 9 figures; Eq.
