Abnormal liver chemistries seen in approximately 3-5% of pregnancies can represent benign processes that will not alter the course of pregnancy, however, can also be a manifestation of life-threatening problems that warrant urgent intervention. Liver disease in pregnancy can be broadly divided into three categories: liver disease that is unique to pregnancy (which will be the focus of this syll...

Algorithms for detecting anomalous events can be divided into those that are designed to detect specific diseases and those that are non-specific in what they detect. Specific detection methods determine if patterns in the data are consistent with known outbreak diseases, as for example influenza. These methods are usually Bayesian. Non-specific detection methods attempt broadly to detect devia...

Introduction Dysfunctional myocardium that remains viable has the potential for contractile recovery after reperfusion. Dysfunctional but viable myocardium has been broadly divided into two closely linked pathophysiological states, myocardial hibernation and stunning. Stunned myocardium is the result of an ischemic insult leading to contractile dysfunction despite adequate reperfusion. Hibernat...

Reference circuits and linear regulators actually have much in common. In fact, the latter could be functionally described as a reference circuit, but with greater current (or power) output. Accordingly, almost all of the specifications of the two circuit types have great commonality (even though the performance of references is usually tighter with regard to drift, accuracy, etc.). This chapte...

The theory Compressive Sensing (CS) has provided a new acquisition strategy and recovery with good in the image processing area. This theory guarantees to recover a signal with high probability from a reduced sampling rate below the Nyquist-Shannon limit. The problem of recovering the original signal from the samples consists in solving an optimization problem. This article presents an overview...

The smear taking practices of departments of genitourinary medicine were investigated by telephone inquiry. Departments seem to be broadly and equally divided into those where the smear is taken before the cervix is wiped or endocervical specimens are taken for microbiology, and those where the smear is taken afterwards. In the unit at Guy's Hospital we compared cervical smears taken in both of...

In the context of database queries, computational methods for handling preferences can be broadly divided into two categories. Query personalization methods consider that user preferences are provided as a user profile separately from the query and dynamically determine how this profile will affect the query results. On the other hand, preferential query answering methods consider that preferen...

The fixed or removable orthodontic appliances mostly use intrinsic force to move teeth. is exerted by the appliance and dissipated against teeth supporting structures. skeletal Class II correctors evolved from various modifications of original activator. These reposition mandible in downward forward direction, activating attached associated muscle. resultant thus created transmitted not only bu...
