Charles Sims suggested that this should be true in [11]. Much work has been done since—see for instance the papers of Thompson [15], Wielandt [17] and Knapp [6]. In particular, Thompson proved in [15] the existence of a function g such that for any G as above there is a prime p and a normal p-subgroup P of G with |Ga: P\ ^ g(d). Nevertheless, the conjecture has remained open until now. As a con...

A hybrid quadrupole orthogonal time-of-flight mass spectrometer optimized for matrix-assisted laser desorption ionization (MALDI) and electrospray ionization has been equipped with a C 60 cluster ion source. This configuration is shown to exhibit a number of characteristics that improve the performance of traditional time-of-flight secondary ion mass spectrometry (TOF-SIMS) experiments for the ...

Objective—To develop and examine the psychometric properties of the Satisfaction with Information about Medicines Scale (SIMS), a new 17-item tool designed to assess the extent to which patients feel they have received enough information about prescribed medicines. Methods—Patients from eight diagnostic categories were recruited at hospitals in London and Brighton and completed the SIMS questio...

BACKGROUND The thyroid's ability to enrich and store iodine has implications for thyroid cancer genesis, progression, and treatment. The study objective was to investigate thyroid iodine content (TIC) in tumoral and extratumoral tissue in patients with papillary thyroid cancer (PTC) as opposed to thyroid healthy controls using two different techniques: X-ray fluorescence (XRF) and time-of-fligh...

The standard approach to integrating heterogeneous information sources is to build a global schema that relates all of the information in the di erent sources, and to pose queries directly against it. The problem is that schema integration is usually di cult, and as soon as any of the information sources change or a new source is added, the process may have to be repeated. The SIMS system uses ...

Charles Sims has asked whether or not, for a free group F , the lower central subgroup γn(F ) coincides with the normal closure in F of the set of basic commutators of weight n. In this paper, we will show that Sims’ question has a positive answer when n = 5. The longest part of the proof is showing that this is true when F has rank 3. Once this is known, the results for higher ranks follow fai...

This paper studies the viability of making a country a developmental state. In particular it studies the characteristics of a developmental state and how they are linked to technology. It then identifies technical education, as a vital force for the creation of a developmental state. In particular it identifies analytical, numeracy, computational and communication skills as vital forces for a s...

BACKGROUND The study on SIMS and SMUS as a whole by Alyaa Mostafa et al showed that after excluding the TVT-S sling, there is no significant difference in patient-reported cure rate and objective cure rate between these two methods. In this paper, we systematically evaluate the relevant data on SIMS-Ajust and TVT-O/TOT and further confirm their safety and effectiveness, providing reliable clini...
