AbslrabTwo gradient descent adaptive algorithms are compared, the LMS algorithm and the LMSNewton algorithm. LMS is simple and practical, and is used in many applications worldwide. LMWewton is based on Newton's method and the LMS algorithm. LMSiNewton is optimal in the least squares sense. It maximizes the quality of its adaptive solution while minimizing the use of training dah. No other line...

Background: Leiomyosarcoma (LMS) of sigmoid colon is an extremely rare neoplasm with poor prognosis, which is often misdiagnosed as colonic adenocarcinoma. The diagnosis of LMS depends on the pathology. The mitosis and the histological grade observation are important for diagnosis. Unlike gastrointestinal stromal tumor, c-KIT in LMS is negative, and immunohistochemistry examination is positive ...

1.0 Introduction For active noise control (ANC) systems, a common approach is to use adaptive FIR filters trained with the filtered-x LMS algorithm [1], for both feedforward systems and Internal Model Control (IMC) feedback systems, in monochannel or multichannel systems. Variations of the algorithm sometimes called the modified filtered-x LMS algorithm have been published [2], which can achiev...

In the cockroach Diploptera punctata, sequencing of the cDNA for the insect myoinhibitory neuropeptide, leucomyosuppressin (LMS), has demonstrated that LMS is the only Phe-Met-Arg-Phe-amide (NH2) (FMRFamide)-related peptide to be encoded by this gene (Donly et al. [1996] Insect Biochem. Mol. Biol. 26:627-637). However, in the present study, high performance liquid chromatography analysis of bra...

BACKGROUND Undifferentiated Pleomorphic Sarcoma (UPS) and high-grade Leiomyosarcoma (LMS) are soft tissue tumors with an aggressive clinical behavior, frequently developing local recurrence and distant metastases. Despite several gene expression studies involving soft tissue sarcomas, the potential to identify molecular markers has been limited, mostly due to small sample size, in-group heterog...

INTRODUCTION Lateral mass screw (LMS) fixation with plates or rods is the current standard procedure for posterior cervical fusion. Recently, implants placed between the facet joints have become available as an alternative to LMS or transfacet screws for patients with cervical spondylotic radiculopathy. The purpose of this study was to evaluate the biomechanical stability of the DTRAX(®) cervic...

SUMMARY This paper proposes a fast and simple adaptive algorithm for MMSE (Minimum Mean Square Error) adaptive array antenna or MMSE combining diversity. This algorithm can be implemented with as a sm...

Learning Management Systems (LMS) have been widely adopted by higher education institutions globally for over a decade. Institutions in sub-Saharan Africa now spend a significant proportion of their limited resources on installing and maintaining these systems. This expenditure continues to increase, raising questions as to whether LMS in these institutions are fulfilling their potential. The a...

BACKGROUND Leiomyosarcoma (LMS) can originate from the retroperitoneum, uterus, extremity, and trunk. It is unclear whether tumors of different origin represent discrete entities. We compared clinicopathologic features and outcomes following surgical resection of LMS stratified by site of origin. METHODS Patients with LMS undergoing resection at a single institution were retrospectively revie...
