we performed molecular dynamics simulations using the coarse-grained model to study the freezing behavior of pure water and 14% water-salt mixture in a wide range of temperatures for a very long time around 50 nanoseconds. for the salty water, an interface in nanoscale was used. for both systems, the freezing behavior of water molecules was studied using some qualities such as density, total en...

Chuck is the biggest and one of the tougher cut of beef carcass. By improving the tenderness of chuck meat it can have a higher value to the consumer. The study was conducted to know the efficacy of tasty kit (containing 1.2 M sodium chloride, 0.25 M sodium bicarbonate and 0.1% ascorbic acid) as a meat preservation and tenderization technique during freezing. Beef chucks from four native bulls ...

This study investigated the potential of isochoric freezing to preserve tomatoes. Isochoric is an emerging technology that preserves biological matter at subfreezing temperatures without any ice damage. was compared with under isobaric conditions and preservation techniques used in food industry: cold storage 10 °C individual quick (IQF). Physicochemical nutritional properties were evaluated we...

A frozen phase transition model is developed to investigate the heat and mass transfer of a single water droplet during the vacuum freezing process. The model is based on the diffusion-controlled evaporation mechanism and phase transition characteristics. The droplet vacuum freezing process can be divided into three stages according to the droplet states and the time order. It includes the evap...

The early layers of a deep neural net have the fewest parameters, but take up the most computation. In this extended abstract, we propose to only train the hidden layers for a set portion of the training run, freezing them out one-by-one and excluding them from the backward pass. We empirically demonstrate that FreezeOut yields savings of up to 20% wall-clock time during training with 3% loss i...

BACKGROUND Freezing of gait (FOG) remains one of the most common debilitating aspects of Parkinson's disease and has been linked to injuries, falls and reduced quality of life. Although commercially available portable cueing devices exist claiming to assist with overcoming freezing; their immediate effectiveness in overcoming gait initiation failure is currently unknown. This study investigated...

TV sent over the networks based on the Internet Protocol i.e. IPTV is moving towards high definition (HDTV). There has been quite a lot of work on how the HDTV is affected by different codecs and bitrates, but the impact of transmission errors over IP-networks have been less studied. This study was focusing on H.264 encoded 1280x720 progressive HDTV and was comparing three different concealment...

background: after improvements in various cancer treatments, life expectancy has been raised, but success in treatment causes loss of fertility in many of the survived young men. cryopreservation of immature testicular tissues or cells introduced as the only way to preserve fertility. however, freezing has some harmful effects. melatonin, a pineal gland hormone, has receptors in reproductive sy...

BACKGROUND Freezing of gait is a debilitating and common gait disturbance observed in individuals with Parkinson's disease (PD). Although the underlying mechanisms of freezing remain unclear, bilateral coordination of steps, measured as a phase coordination index, has been suggested to be related to freezing. Phase coordination index has not, however, been measured during tasks associated with ...
