Near-infrared (NIR) spectrometry will present a more promising tool for quantitative measurement if the robustness and predictive ability of the partial least square (PLS) model are improved. In order to achieve the purpose, we present a new algorithm for simultaneous wavelength selection and outlier detection; at the same time, the problems of background and noise in multivariate calibration a...

When entering foreign markets, software firms need to make a fundamental choice on the distribution arrangements for software and related services. This choice may involve contracting with local partners or entering foreign markets through company-owned channels. This study focuses on analyzing such boundary choices of software product firms in international markets. Taking a knowledge-based pe...

In recent years, many firms have adopted outsourcing as a means to govern their information technology (IT) operations. While outsourcing is associated with several important benefits, it also entails risk. The main purpose of this study was to validate measures of the risk factors associated with outsourcing IT operations. Insights from transaction costs theory suggest that risk factors are in...

BACKGROUND Loss-of-function point mutations in the cathepsin C gene are the underlying genetic event in patients with Papillon-Lefèvre syndrome (PLS). PLS neutrophils lack serine protease activity essential for cathelicidin LL-37 generation from hCAP18 precursor. AIM We hypothesized that a local deficiency of LL-37 in the infected periodontium is mainly responsible for one of the clinical hal...

various studies on the national policy on education (npe) have concentrated on the cognitive value of pedagogy and learning of the language aspect but few have viewed its importance on the togetherness of the nation - nigeria. this paper deals with how the language policy can influence and ensure the co-existence of nigeria in achieving self-actualisation, national unity, social, cultural, econ...

Partial least squares (PLS) is sometimes used as an alternative to covariance-based structural equation modeling (SEM). This paper briefly reviews currently available SEM techniques, and provides a critique of the perceived advantages of PLS over covariance-based SEM as commonly cited by PLS users. Specific attention is drawn to the primary disadvantage of PLS, namely the lack of consistency of...

BACKGROUND Motor neuron diseases can affect the upper motor neuron and/or the lower motor neuron. Both amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS) are motor neuron diseases, and there is much debate as to whether these are 2 separate disorders or simply 2 points on a continuum. OBJECTIVE To determine which clinical features at onset and during follow-up could help ...

Using solid state radioimmunoassays developed by the first author, changes in the urine level of plasmin-like substances (PLS) and fibrin degradation products (FDP) before and after human kidney transplantation were determined in 49 transplant patients. Averages of urine PLS and FDP in a normal population of 51 persons were 0.13+/-0.10 (SD) and 0.14+/-0.07 microng/ml, respectively. In all trans...

Neuronal cells are susceptible to many stresses, which will cause the apoptosis and neurodegenerative diseases. The precise molecular mechanism behind the neuronal protection against these apoptotic stimuli is necessary for drug discovery. In the present study, we have found that plasmalogens (Pls), which are glycerophospholipids containing vinyl ether linkage at sn-1 position, can protect the ...

4 We build connections between envelopes, a recently proposed context for efficient estima5 tion in multivariate statistics, and multivariate partial least squares (PLS) regression. In partic6 ular, we establish an envelope as the nucleus of both univariate and multivariate PLS, which 7 opens the door to pursuing the same goals as PLS but using different envelope estimators. It 8 is argued that...
