To design DNA nano-machines or analyze DNA molecular reactions, it is important to be able to predict the energy landscape of molecular structures and the energy barrier of a transition between structures on the landscape. Unfortunately, this is difficult for DNA molecules longer than 100 bases. In this paper, we propose an effective new technique for analyzing a structural transition over a DNA energy...
Conclusions To make a standard diagnosis, it is important to have a standard lexicon. Although many kinds of expression are possible for the same feature of a breast tumor, a technical term must be a word that is seldom confused with another different concept. Especially, a halo or boundary high echo must be a word that is used to express a malignant sign.
Summary We assessed the ultrasonographic appearance and clinical implication of bilateral breast involvement in three cases of acute leukemia: L1, L3, and M1 of the FAB subtype. Breast involvement was observed in one case at the initial presentation and in two cases at relapse after bone marrow transplantation. Common findings of ultrasonograms of the cases were hypoechoic masses with diffusely mixed...
Conclusions Many aspects of internal echoes of mass image-forming breast lesions have been discussed. These points, as well as other themes, should be documented or corrected through further investigation in wide clinical practice.
Summary For various soft tissues (e.g., liver, breast), we are developing the ultrasonic strain measurement-based mechanical properties (e.g., shear modulus, viscoshear modulus) reconstruction/imaging technique. To clarify the limitation of our quantitative reconstruction/imaging technique as a diagnostic tool for differentiating malignancies, together with improving the spatial resolution and dynamic...
Conclusions We have reported the Diagnostic Guidelines for Non-Mass Image-Forming Lesions. These have been discussed in the subcommittee of the Japan Association of Breast and Thyroid Sonology (JABTS) and the Japan Society of Ultrasonics in Medicine. This report is now the draft. We will discuss it further, and it will become a useful guideline for the ultrasonic diagnosis of breast cancers.
Admission control (AC) is an important feature in a wireless network by which radio resource usage is optimized whilst maintaining the Quality of Service (QoS) of existing users. In this paper, a novel admission control mechanism is proposed for the Long-Term Evolution (LTE) cellular networks. Simulation results show that the proposed AC can provide a more flexible trade-off between network and user...
In this paper, we consider the related issues of pre-emption and congestion control in Long Term Evolution (LTE) networks. A load-reduction method which can be used for either pre-emption or congestion control is described and evaluated by simulation. The simulation results show that the proposed mechanism can significantly improve dropping and blocking probabilities, depending on the bearer priorities.
