Both compression and decompression play important roles in a web service system. High compression ratio helps to save the storage, while fast decompression contributes to decreasing the response time of service. Specifically focusing on the news web service, this paper proposes a compression mechanism to improve the efficiency of compression and decompression simultaneously by taking advantage ...

abstract our patient was a 43-year-old woman with a suboccipital headache and pain in the upper cervical region from 3 years ago with a progressive generalized weakness in the last 3 months. neuroimaging study showed a dumbell shaped lesion with compression of the spinal cord in the cervical region that was identified as a neurinoma. the tumor had been completely removed by surgery but after th...

Background: Although cryotherapy is still the first-line therapy for solar lentigines, due to side effects such as post-inflammatory hyperpigmentation (PIH), especially in patients with darker skin types, pigment specific lasers should be considered as initial treatment. The aim of this study was to evaluate the efficacy and safety of cryotherapy in comparison with 595-nm pulsed dye laser (PDL)...

BACKGROUND Spinal cord compression is a known cause of spinal cord injury. The purpose of this study is to measure pressure response during graded spinal cord compression. This information will be important in evaluating the amount of canal compromise that can be tolerated before risking neurological injury secondary to cord compression. To date, there is no published study that has evaluated p...

Stress relaxation and structural analysis were used to investigate the zonally differentiated microstructural response to compression of the integrated cartilage-on-bone tissue system. Fifteen cartilage-on-bone samples were divided into three equal groups and their stress relaxation responses obtained at three different levels of axial compressive strain defined as low (~20%), medium (~40%) and...

Compression therapy, a well-recognized treatment for lymphoedema and venous disorders, pressurizes limbs and generates massive non-noxious afferent sensory barrages. The aim of this study was to study whether such afferent activity has an analgesic effect when applied on the lower limbs, hypothesizing that larger compression areas will induce stronger analgesic effects, and whether this effect ...

In a primary spinal cord injury, the amount of mechanical compression insult that the neurons experience is one of the most critical factors in determining the extent of the injury. The ultrastructural changes that neurons undergo when subjected to mechanical compression are largely unknown. In the present study, using a compression-driven instrument that can simulate mechanical compression ins...

Bystander cardiopulmonary resuscitation (CPR) improves out-of-hospital cardiac arrest (OHCA) survival. In settings with prolonged ambulance response times, skilled bystanders may be even more crucial. In 2010, American Heart Association (AHA) and European Resuscitation Council (ERC) introduced compression-only CPR as an alternative to conventional bystander CPR under some circumstances. The pur...

The aim of this study was to investigate the changes in activation of the musculoskeletal system in response to soft-tissue vibrations with different compression conditions (externally applied) in a drop-jump landing task. Twelve trained male participants were instructed to perform drop-jump landings from 3 heights in compression shorts (CS) and regular shorts without compression (CC). External...

The temporal limitations of the human visual system (HVS) are usually not fully explored in the quantization stage of today’s video encoders. In this paper we present a novel method to improve the compression efficiency of popular video compression algorithms in which the temporal frequency response characteristics of the HVS are taken into account while building macroblockspecific quantization...
