STUDY OBJECTIVE To evaluate the accuracy of traditional blind uterine sounding in measuring uterine cavity length (UCL), compared with measurement by hysteroscopic guidance. DESIGN A cross-sectional descriptive study (Canadian Task Force classification III). SETTING Academic multispecialty medical center. PATIENTS Fifty-eight women undergoing elective hysteroscopic procedures. INTERVENT...

crowdsourcing should be aware of the approach’s significant limitations and biases, and of the need to sort through and verify large amounts of information of uneven reliability. Furthermore, crowdsourcing tends to work better when the goal is to quickly compile and share knowledge that is already available, rather than as a means to engage in original research. Crowdsourcing cannot replace mor...

Non-visual senses can be used in toys to enhance and enrich the play experience. Previous research has shown that – especially for young children developing sensory-motor skills – exploration and play are two tightly linked activities: everything is new and needs to be “studied”, and playful behaviors emerge from active exploration. The main idea of this paper is to provide a new approach in de...

Characterisation of the shallow water acoustic communications channel involves the analysis of sounding data. Chirp signals have many properties which make them an attractive choice for channel sounding. They are easily generated and channel responses can be processed in the time or frequency domain for channel estimation. In the rapidly varying shallow water environment time domain techniques ...

This paper develops methods for estimating the rotation rate of a spacecraft using only measured magnetic field data. The goal is to provide rate information for use in applications such as de-tumbling, nutation damping, and momentum management without using gyroscopes. Two algorithms are developed, a deterministic algorithm and an extended Kalman filter. Both algorithms employ the magnetic fie...

abstract deep seated cavernous angioma (ca) is a very rare entity, those occurring in the hypothalamus are still less common. we present a case of a 52-year-old man who presented with behavior and memory disturbance attacks. he had a ca of the hypothalamus as revealed by magnetic resonance imaging (mri). we will discuss the role and importance of imaging in such scenario and also the differenti...

Among all geophysical techniques, electrical resistivity and magnetic surveying as an integrative approach has been used widely for archaeological prospection at different scales of investigations. In this study, DC (1D vertical sounding and/2D/3D ERT) surveys (total gradient) a multi-scale was applied in highly terraneous site (Tell) with case study to characterize image the various assets dep...
