The presence of noise and absence of contrast in electron micrographs lead to a reduced resolution of the final 3D reconstruction, due to the inherent limitations of single-particle image alignment. The fast rotational matching (FRM) algorithm was introduced recently for an accurate alignment of 2D images under such challenging conditions. Here, we implemented this algorithm for the first time ...

One of the efficient and most popular technique for designing sharp 1-D linear phase FIR filters is the Frequency Response Masking (FRM) approach. It is an effective method for the design of high speed , low power, sharp FIR digital filters with a small number of non-zero coefficients. Very recently, a modified McClellan transformation(T1 and T2) is proposed (JieCherng Liu and Yang-Lung Tai, 20...

Two authors of this paper have shown that by using the frequency-response masking (FRM) technique for designing finite-impulse response (FIR) filters building a two-channel filterbank (FB) with rational sampling factors, the implementation complexity can be reduced compared with the use of direct-form filters for this purpose. In this paper, for designing FBs, a modified version of the FRM tech...

In this report, we revisit a much explored topic in networking the search for a simple yet fully general and efficient multicast design. The many years of research into multicast routing have led to a generally pessimistic view that the complexity of multicast routing and interdomain multicast in particular can only be overcome by restricting the service model, as in the case of single-source m...

The use of highly enriched uranium (HEU) as fuel in research reactors runs contrary to the concept of proliferation-resistant nuclear technologies. Consequently, for more than two decades, international activities have been undertaken to terminate the use of HEU in research reactors by supporting the conversion of these facilities to low-enriched uranium (LEU). Achievements, setbacks and perspe...

BACKGROUND Fractional technology overcomes the problems of ablative lasers, such as inaccurate depth control and damage to the epidermis. Minimally invasive fractional radiofrequency microneedle devices allow for more-selective heating of the dermis. OBJECTIVE To evaluate the clinical efficacy of fractional radiofrequency microneedle (ERM) treatment in acne scars and large facial pores. MAT...

Fluid losses (measured by body weight changes) and voluntary fluid intakes were measured in elite basketball, netball, and soccer teams during typical summer and winter exercise sessions to determine fluid requirements and the degree of fluid replacement. Each subject was weighed in minimal clothing before and immediately after training, weights, and competition sessions; fluid intake, duration...

Objective. The aim of this study was to describe critical care for obstetrical hemorrhage, especially in cases of uterine inversion. Study Design. We extracted data for six patients diagnosed with uterine inversion concerning resuscitation. Results. The shock index on admission of the six patients was 1.6 or more on admission. Four of the six experienced delay in diagnosis and received inadequa...

A Forced Roll Mechanism was designed and built at the Hydromechanics Laboratory at the United States Naval Academy. The FRM was designed as a dynamometer that forces a planing hull model in roll and measures the resulting roll moment as well as the heave and sway forces. The model is fully restrained in all six degrees of freedom. The dynamometer can be configured to either oscillate the model ...
