چکیده

With smart devices being an essential part of our everyday lives, unsupervised access to the mobile sensors' data can result in a multitude side-channel attacks. In this paper, we study potential leaks from Apple Pencil (2nd generation) supported by iPad Pro, latest stylus pen which attaches body magnetically for charging. We observe that Pencil's affects magnetic readings sensed iPad's magnetometer when user is using Pencil. Therefore, ask: Can infer what writing on screen with Pencil, given only motion data? To answer question, present Side-channel attack Stylus pencil through Sensors (S3), system identifies sensor readings. first use sharp fluctuations determine iPad. then introduce high-dimensional particle filter track location and orientation during usage. Lastly, guide particles, build map serving as bridge between measured orientation. evaluate S3 10 subjects demonstrate correctly identify 93.9%, 96%, 97.9%, 93.33% letters, numbers, shapes, words having data.

We sought to characterize WPEC by quantifying per-hour log-fold change. To do so, we regressed the log gene expression on time (hour) and extracted the linear slope. For genes with monotonically increasing or decreasing expression trajectories, the utility of our WPEC measure to discriminate is obvious. Our WPEC measure can also discriminate with more complex trajectories which may be reflectiv...

study design, analysis and interpretation The following table summarizes several key concepts relating to sample preparation and library construction that may influence analysis and interpretation of RNA-seq data. Several initiatives are underway to develop standards and best practices that cover many of these concepts. These include: the Sequencing Quality Control (SEQC) consortium [2], the En...

We estimated clinic-averaged co-ancestries from WGS data assuming SNPs were both linked and unlinked. Linked analyses require a recombination file specifying distances between SNPs. We used a uniform recombination rate equal to 7.4 × 10−7 Morgans per base pair (Miles et al. 2016), the same as that specified in hmmIBD (Schaffner et al., n.d.). ChromoPainter essentially treats each unlinked SNP a...

We here report a statistical fact in support of the basic assumption underlying our model. The matching condition we employ dictates a certain correlation between the sets of regulated genes by each TF: if the binding sequence of a TF (A) is embedded in that of a TF (B), then the set of genes {Gi}B regulated by TFB in our model is a subset of {Gi}A. A similar investigation of the yeast database...
