We examine 82 situations where the market value of a company is less than its subsidiary. These situations imply arbitrage opportunities, providing an ideal setting to study the risks and market frictions that prevent arbitrageurs from immediately forcing prices to fundamental values. For 30 percent of the sample, the link between the parent and its(More)
We consider a real-time streaming system where messages created at regular time intervals at a source are encoded for transmission to a receiver over a packet erasure link; the receiver must subsequently decode each message within a given delay from its creation time. We study a bursty erasure model in which all erasure patterns containing erasure bursts of(More)

Inadequately breastfed infants are likely to be undernourished and have childhood infections. EBF knowledge and infant feeding practices have(More)

Most multiple sclerosis (MS) patients eventually suffer from mobility impairment, and thus it is critical that walking disability in MS be accurately assessed. The six-minute walk test (6MWT), a reliable MS measure, is traditionally used to determine the distance covered in six minutes using a standard protocol. With the availability of body sensor networks(More)
Multiple sclerosis (MS) is a neurological disorder that disrupts the communication within the brain, and between the brain and body. MS symptoms may vary over time. So we propose to do longitudinal assessments of a patient's gait characteristics using inertial data, in order to evaluate his/her gait for an extended period of time.
BACKGROUND The incidence of type 2 diabetes in pregnancy is rising and rates of serious adverse maternal and fetal outcomes remain high. Metformin is a biguanide that is used as first-line treatment for non-pregnant patients with type 2 diabetes. We hypothesize that metformin use in pregnancy, as an adjunct to insulin, will decrease adverse outcomes by(More)
The Empirical Mode Decomposition (EMD) algorithm was introduced as the first step of the Hilbert-Huang Transform, proposed by Huang et al. (1998). EMD decomposes a signal into so-called Intrinsic Mode Functions (IMFs) in a systematic way. Since then, various versions of EMD have been developed, addressing weaknesses of the original EMD procedure and aiming(More)
