This paper examines the Asymmetric AdaBoost algorithm introduced by Viola and Jones for cascaded face detection. The Viola and Jones face detector uses cascaded classifiers to successively filter, or reject, non-faces. In this approach most non-faces are easily rejected by the earlier classifiers in the cascade, thus reducing the overall number of computations. This requires earlier cascade cla...

-In this paper, we propose a design method of the narrow band FIR filter in a Fluency signal space. As a result, we can make superior narrow band FIR filters than ordinary one. While an FIR filter has advantages that it is stable and can realize perfect linear phase, its transfer function can be of higher order according to desired accuracy. One of such difficult classes that indeed requires lo...

The insulin signaling pathway is of pivotal importance in metabolic diseases, such as diabetes, and in cellular processes, such as aging. Insulin activates a tyrosine phosphorylation cascade that branches to create a complex network affecting multiple biological processes. To understand the full spectrum of the tyrosine phosphorylation cascade, we have defined the tyrosine-phosphoproteome of th...

Alzheimer's disease (AD) is characterized by slowly progressive neuronal death, but its molecular cascade remains elusive for over 100 years. Since accumulation of autophagic vacuoles (also called granulo-vacuolar degenerations) represents one of the pathologic hallmarks of degenerating neurons in AD, a causative connection between autophagy failure and neuronal death should be present. The aim...

The collagen type II alpha 1 (COL2A1) mutation causes severe skeletal malformations, but the pathogenic mechanisms of how this occurs are unclear. To understand how this may happen, a col2a1 p.Gly1170Ser mutated mouse model was constructed and in homozygotes, the chondrodysplasia phenotype was observed. Misfolded procollagen was largely synthesized and retained in dilated endoplasmic reticulum ...

The campus of Tallinn University Technology consists 26 buildings with a total annual heat demand approximately 20 GWh. A local natural gas-fired boiler provides annually 13 GWh heating to 12 in the and 14 are connected district system. This paper analyses possibilities replacing gas heating. Two systems were modelled using EnergyPRO software compared reference system network: connection an exi...

There may be a pathological connection between cardiac failure and ischemic stroke. In this article we describe pertinent research that demonstrates subsequent death of cardiac and neural myocytes in the post ischemic stroke brain. Current stroke therapy overlooks the connection between cardiac and cerebrovascular events and fails to address the shared risk factors. Current pre-clinical stroke ...

Objective(s): Haemostasis prevents blood loss following vascular injury. It depends on the unique concert of events involving platelets and specific blood proteins, known as coagulation factors. The clotting system requires precise regulation and coordinated reactions to maintain the integrity of the vasculature. Clotting insufficiency mostly occurs due to genetically inherited coagulation fact...
