K-means algorithm is an effective clustering based on partition, which has been widely used for analysis. However, there are two main problems algorithm: how to provide appropriate number of clusters and determine initial cluster centers automatically. Plenty methods have proposed address the above problems. In our previous work, we hierarchical initialization approach centers, but cannot this paper, in order automatically, propose Davies Bouldin Index (DBI) (DHIKM) basis work. The can...
Graphics Processing Units (GPUs) can easily outperform CPUs in processing large-scale data parallel workloads, but are considered weak serialized tasks and communicating with other devices. Pursuing a CPU-GPU collaborative computing model which takes advantage of both devices could provide an important breakthrough realizing the full performance potential heterogeneous computing. In recent years platform vendors runtime systems have added new features such as unified memory space dynamic...
The warm Gulf Stream sea surface temperatures strongly impact the evolution of winter clouds behind atmospheric cold fronts. Such cloud remains challenging to model. is too wide within ERA5 and MERRA2 reanalyses, affecting turbulent fluxes. Known problems boundary layer (too-dry too-cool with strong westerlies), ascertained primarily from ACTIVATE 2020 campaign aircraft dropsondes secondarily older buoy measurements, reinforce flux biases. In contrast, winds air-sea temperature/humidity...
Large-eddy simulation (LES) is able to capture key boundary-layer (BL) turbulence and cloud processes. Yet, large-scale forcing surface turbulent fluxes of sensible latent heat are often poorly prescribed for LES simulations. We derive these quantities from measurements reanalysis obtained two cold air outbreak (CAO) events during Phase I the Aerosol Cloud meTeorology Interactions oVer western ATlantic Experiment (ACTIVATE) in February-March 2020. study contrasting CAO cases by performing...

Abstract This study examines boundary layer turbulence derived from high temporal resolution meteorological measurements 40 research flights over the western North Atlantic Ocean during 2020 deployments of ACTIVATE. Frequency distributions various turbulent quantities reveal stronger winter deployment than in summer and for cloud‐topped cloud‐free layers deployment. Maximum kinetic energy (TKE) is most often within cloud observations summer, whereas it mostly below both seasons by a global...
Abstract The winter synoptic evolution of the western North Atlantic and its influence on atmospheric boundary layer is described by means a regime classification based Self‐Organizing Maps applied to 12 years data (2009–2020). regimes are classified into categories according daily 600‐hPa geopotential height: dominant ridge, trough ridge eastward transition (trough‐ridge), trough, (ridge–trough). A fifth resembles climatological mean. Coherent changes in sea‐level pressure large‐scale winds...
Abstract Postfrontal clouds (PFC) are ubiquitous in the marine boundary layer, and their morphology is essential to estimating radiation budget weather climate models. Here we examine roles of sea surface temperature (SST) meteorological factors controlling mesoscale evolution shallow associated with a cold-air outbreak that occurred on 1 March 2020 during phase I Aerosol Cloud Meteorology Interactions over Western Atlantic Experiment (ACTIVATE). Our results show simulated PFC structure...
Currently, the prevalence of Android malware remains substantial. Malicious programs increasingly use advanced obfuscation techniques, posing challenges for security professionals with enhanced disguises, a proliferation variants, and escalating detection difficulty. Leveraging semantic features presents promising avenue to address these challenges. Rich information encapsulated within opcodes API call graphs has been identified as crucial in distinguishing benign from malicious...
Numerical simulation of turbulent fluid dynamics needs to either parametrize turbulence—which introduces large uncertainties—or explicitly resolve the smallest scales—which is prohibitively expensive. Here, we provide evidence through analytic bounds and numerical studies that a potential quantum speedup can be achieved simulate using computing. Specifically, lattice Boltzmann formulation for which give low-order Carleman linearization much more accurate than previously believed these...
Monocentric, retrospective, cross-sectional study.

Degenerative changes spine with aging alter balance, causing pathologies. However, there was a lack comprehensive study on alignment relationship during degenerative evolution. Among total 1,370 volunteers, 701 volunteers were recruited. Participants underwent lateral X-ray, assessed...
