The teachers and the school authorities often call the parents in connection with a child’s ‘performance’ in school. The children have to face the wrath of both the parents and the teachers. This tension slowly builds up and the child decides to quit the school forever. This paper analyzes the causes for dropouts and concentrates mainly on the tensions experienced by teachers, parents and the s...

Single-cell RNA sequencing is able to quantify the whole transcriptome from the small amount of RNA present in individual cells. However, a consequence of reverse-transcribing and amplifying small quantities of RNA is a large number of dropouts, genes with zero expression in particular cells. The frequency of dropout events is strongly non-linearly related to the measured expression levels of t...

In the robust secure aggregation problem, a server wishes to learn and only sum of inputs number users while some may drop out (i.e., not respond). The identity dropped is known priori needs securely recover remaining surviving users. We consider following minimal two-round model aggregation. Over first round, any set no fewer than <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" ...

We propose a numerical procedure to design a linear output-feedback controller for a remote linear plant in which the loop is closed through a network. The controller stabilizes the plant in the presence of delays, sampling, and packet dropouts in the (sensor) measurement and actuation channels. We consider two types of control units: anticipative and non-anticipative. In both cases the closedl...

The analysis of single-cell RNA-seq (scRNA-seq) data is complicated and biased by excess zero or near zero counts, the so-called dropouts due to the low amounts of mRNA sequenced within individual cells. We introduce scImpute, a statistical method to accurately and robustly impute the dropouts in scRNA-seq data. scImpute is shown as an effective tool to enhance the clustering of cell population...

This paper presents a novel design strategy for networked control systems, where a centralized controller needs to divide its attention between various actuators. Communication is via an unreliable network affected by data-dropouts and which allows access to only one actuator node at a time. To achieve good performance, control and network protocol are co-designed and signal predictions are sen...

The purpose of this study was to examine the association of beliefs and attitude related to smoking and smoking behavior among school dropouts in a national sample (weighted N = 492,352). The self-reported smoking rate for school dropouts was 58.3%. Those who were most positive about smoking (such as smoking helps people reduce stress and relax, reduce boredom) were more likely to be smokers (p...
