It is important to preprocess high-throughput data generated from microarray or mass spectrometry experiments in order to obtain a successful analysis. Outlier detection is an important preprocessing step. For outlier detection, upper and lower fences (Q3+1.5IQR and Q1 − 1.5IQR) of the differences are often used in statistics, where Q1=lower 25% quantile, Q3=upper 25% quantile, and IQR = Q3 − Q...

As a versatile and valuable intermediate, furfuryl alcohol (FOL) has been widely used in manufacturing resins, vitamin C, perfumes, lubricants, plasticizers, fuel additives, biofuels, other furan-based chemicals. This work developed an efficient hybrid strategy for the valorization of lignocellulosic biomass to FOL. Corncob (75 g/L) was catalyzed with heterogenous catalyst Sn-SSXR (2 wt%) gener...

Chitin, the natural biocompatible and biodegradable polymer consists of β-(1→4) linked 2-acetamido-2-deoxy-Dglucopyranose repeating units, but has limited pharmaceutical and biomedical applications owing to its insolubility in common solvents, although it is the second most abundant natural polymer in the world synthesized by a large number of living organisms. In the present investigation, a s...

This thesis considers the nucleation and growth, synthesis, and catalytic application of metallic nanoparticles at liquid|liquid interfaces. It comprises five publications, a previously unpublished synthesis of polymer coated palladium nanoparticles, and an introduction to the relevant literature. Three publications are concerned with electrodeposition of metal nanoparticles at liquid|liquid in...

In the area of static scheduling, list scheduling is one of the most common heuristics for the temporal and spatial assignment of a Directed Acyclic Graph (DAG) to a target machine. As most heuristics, list scheduling assumes fully connected homogeneous processors and ignores contention on the inter communication links. This article extends the list scheduling heuristic for contention aware sch...

In past years there has been increasing interest in field of Wireless Sensor Networks (WSNs). One of the major issue of WSNs is development of energy efficient routing protocols. Clustering is an effective way to increase energy efficiency. Mostly, heterogenous protocols consider two or three energy level of nodes. In reality, heterogonous WSNs contain large range of energy levels. By analyzing...

• PdCu single atom alloys (SAA) selectively catalyse furfural hydrogenation. Successful deposition of Pd atoms on Cu nanoparticles via galvanic replacement. SAAs are catalytically superior to monometallic and catalysts. host enhance hydrogen dissociative adsorption. Single-atom catalysts serve as a skilful control precious metals heterogenous where all active sites accessible for catalytic reac...

Recently, several model matching tools emerged that compute the corresponding elements of two different models. Having a closer look at concrete matching scenarios, one may find different cases such as matching different versions of one model, e.g., model evolution, or matching heterogenous models that do not have a common predecessor. Especially, the latter case is interesting as a first step ...

BACKGROUND Immunohistochemical staining for mismatch repair proteins is efficient and widely used to identify mismatch repair defective tumors. The tumors typically show uniform and widespread loss of MMR protein staining. We identified and characterized colorectal cancers with alternative, heterogenous mismatch repair protein staining in order to delineate expression patterns and underlying me...

Palmoplantar keratodermas are a heterogenous group of diseases, one of them is Papillon-Lefevre Syndrome (PLS). This rare disease is inherited as autosomal recessive and characterized by focal hyperkeratotic plaques on elbows and knees, severe periodontal disease resulting in premature loss of teeth. We report two brothers with PLS who did not have a history of this disease in their famil...
