The calculation of apparent resistivities, based on the model of a homogeneous half-space, is commonly the first step in Ž . order to evaluate helicopter electromagnetic HEM data. Due to the increase in frequencies used in HEM systems, survey results are not only displayed as apparent resistivity maps but also as cross-sections that require resistivity and depth information. After a brief descr...

We propose an extension of the expectation-maximization (EM) algorithm, called the hyperpenalized EM (HEM) algorithm, that maximizes a penalized log-likelihood, for which some data are missing or unavailable, using a data-adaptive estimate of the penalty parameter. This is potentially useful in applications for which the analyst is unable or unwilling to choose a single value of a penalty param...

We motivate and describe a mode of operation HEM (resp., THEM) that turns a n-bit blockcipher into a variable-input-length cipher (resp., tweakable cipher) that acts on strings of [n..2n − 1] bits. Both HEM and THEM are simple and intuitive and use only two blockcipher calls, while prior work at least takes three. We prove them secure in the sense of strong PRP and tweakable strong PRP, assumin...

OBJECTIVE The aim of this study was to determine the accuracy of the Omron HEM-7320-LA with Intelli Wrap technology cuff HEM-FL1 for self-measurement and clinic blood pressure (BP) measurement according to the European Society of Hypertension International Protocol revision 2010. PARTICIPANTS AND METHODS The evaluation was performed in 39 individuals. The mean age of the participants was 47.9...

A 58-year-old man underwent laparoscopy-assisted distal gastrectomy (LADG) with Billroth I gastroduodenostomy due to early gastric cancer. During surgery, the perigastric vessels were ligated with Hem-o-Lok clips. Esophagogastroduodenoscopy (EGD) 6 months later showed a fungating mass at the anastomosis site. Repeat EGD 1 year after LADG showed a Hem-o-Lok clip at the fungating mass lesion. Bec...

OBJECTIVE - The aim of our study was to assess the profile of a wrist monitor, the Omron Model HEM-608, compared with the indirect method for blood pressure measurement. METHODS - Our study population consisted of 100 subjects, 29 being normotensive and 71 being hypertensive. Participants had their blood pressure checked 8 times with alternate techniques, 4 by the indirect method and 4 with the...

BACKGROUND The aim of this study was to validate the Omron HEM-907 blood pressure (BP) measuring device according to the international validation protocol. DESIGN The international validation protocol is divided into two phases: the first phase is performed on 15 selected subjects and if the device passes this phase, 18 more subjects are selected making a total number of 33 subjects on which ...
