UltraPerformance LC (UPLC) in hydrophilic interaction chromatography (HILIC) separation mode is becoming a routine and widely recognized technique for rapid, efficient, sensitive, and reproducible analysis of 2-aminobenzamide (2-AB) labeled glycans. Even though 2-AB is now the most common glycan labeling reagent, its use is limited by low MS sensitivity. Recent reports on LC/FLR/MS of glycans t...

Human gaze has hidden potential for the interaction between the user and the computer. Eye-tracking techniques have been utilized in psychological research, for testing empirically human perceptual or cognitive processes. Likewise, eye-tracking is well fitted for the use of testing software usability, or for example the effectiveness of marketing materials, because those tests are typically set...

Background Sensitization to food allergens is supposed mostly to be caused by ingestion of the allergen. However, sensitization may also be initiated in the respiratory tract or through the skin. Little is known about sources and prevalence of food allergens in environmental samples. We aimed to describe the presence of food allergens in mattress dust from the homes of 13 year old Norwegian ado...

In this note based on paper [3] we deal with domains D (i.e. connected open subsets) of a Finsler manifold (M, F ). At first we carry out a comparison between different notions of convexity for their boundaries. Then a careful application of variational methods to the geodesic problem yields that the convexity of ∂D is equivalent to the existence of a minimal geodesic for each pair of points of...

This paper develops and analyzes a principal-agent model for product specification and production motivated by “core buying” decisions at Ford Motor Company. This model focuses on two important elements of the “core” buyer’s responsibility: (1) assessing the supplier’s capability and (2) allocating some or all of a fixed level of some buyer-internal resource to help the supplier. Under the cont...

this paper has used a multisectoral input-output model of iranian economy to examine the ability of different sectors of economy to create jobs per unit of output as well as capital. the results reveal that there is no conflict in a growth strategy that simultaneously attempts to improve efficiency i.e. reallocating production to sectors with low drcs, equity and job creation. although sectoral...

We present the use of human physiological tremor, detected by a linear accelerometer, as a novel form of input for mobile devices. This allows the device to be aware if it is being held in a human hand, and in which posture. It also has security applications, as human tremor characteristics are individual. We describe two simple demonstrations of the use of tremor. One demo uses isometric muscl...
