STDU Viewer's strong suit is managing multiple different documents at once. Not only can you open documents in tabs and expand a navigation panel, but you can also create and navigate bookmarks and highlights, view thumbnails of your open documents, and split windows to compare different pages within the same document. Another neat feature is that you can invert colors, such as from black on white to white on black, which can reduce eyestrain.

The differentiation of Lewy body dementia from other common dementia types clinically is difficult, with a considerable number of cases only being found post-mortem. Consequently, there is a clear need for inexpensive and accurate diagnostic approaches for clinical use. Electroencephalography (EEG) is one potential candidate due to its relatively low cost and non-invasive nature. Previous studies examining the use of EEG as a dementia diagnostic have focussed on the eyes closed (EC) resting state; however, eyes open (EO) EEG may also be a useful adjunct to quantitative analysis due to clinical availability.
As a tool for assisting in dementia research, EEG is most often recorded in an eyes closed resting state (EC) where participants remain awake while performing no task or movements. It has been shown that, during EC resting state EEG, dementia patients display a definite decrease in power for the alpha frequency range within the EEG spectrum when compared to healthy participants [18, 19].
A similar procedure can be performed with eyes kept open (EO), commonly used for the diagnosis of conditions such as epilepsy or other seizure-related neurological conditions. In this case, participants are asked by their clinician to open and close their eyes [20]. This is currently not widely utilised for dementia research despite the routine EO EEG data acquisition in clinical neurophysiology, as during EO EEG the alpha peak of dementia patients does not display the same significant decrease when compared to healthy participants. Recently, however, a significant impairment has been found within the EO resting state alpha reactivity of LBD patients when compared to those with AD, thus representing the need for further investigation into the EO dataset [21].
From the original 98 subjects, 65 were used for analysis, including 15 HC, 12 AD, 21 DLB and 17 PDD subjects. The other 33 patients (2 HC, 13 AD, 4 DLB, 4 PDD) were removed from the dataset due to participants not having at least 20 s of combined resting state eyes closed or eyes open EEG after cleaning [13]. This criterion was employed because 20 s of continuous resting state EEG has been shown to be the required amount to account for the inherent variability in EEG [27].
From the one-way four group ANOVA, it was found that there were significant differences for the eyes closed DF between the HC and dementia groups in the parietal and occipital regions, with dementia groups displaying a mean slowing in their DF towards the high theta frequency range. Additionally, we found the same significant difference between the HC and dementia patients DF in the EO resting state within the same regions. These results are displayed in supplementary Table 5.
The pupil is the black circle in the center of the iris, which is really an opening in the iris, and it lets light enter the eye. To see how this works, use a small flashlight to see how your eyes or a friend's eyes respond to changes in brightness. The pupils will get smaller when the light shines near them and they'll open wider when the light is gone.

VA understands that many Veterans are especially concerned about exposure to the smoke and fumes generated by open burn pits. In Iraq, Afghanistan, and other areas of the Southwest Asia theater of military operations, open-air combustion of trash and other waste in burn pits was a common practice. The Department of Defense has now closed out most burn pits and is planning to close the remainder. Depending on a variety of factors, you may experience health effects related to this exposure. Factors that may indicate you have a greater or lesser risk of short or long-term health effects include:
The Line by Richard Hague The child lay in a plain box lined with quilt scraps. The skin of its face and hands was pearly, though there was no depth to its luminescence. The gray noon light that entered the open door and explored the farthest corners of the room lit, exactly as it did the child, the broken radio, the piles of clothes, the drawerless bureau stuffed with pots and boxes, the random bundles of kindling. The mother sat in the doorway connecting the front room and the kitchen. The box containing the child lay across the seat of a wooden chair in the middle of the room. A straight line could have been drawn between the first branch of the dead oak visible across the road, through the open front door, across the folded hands of the child in the box, directly through the heart of the mother sitting just before the kitchen entrance, and on out the kitchen window behind her into the desperate rampage of the woods and beyond. In fact there was such a line; though invisible, it connected all these things and more, and along it ran a slightly vibrating darkness, a troubled dusk that lived, alien and unexpected , despite the time of day. As the younger boy came in, he instinctively avoided this line, stepping sideways through the door and then sneaking along the piles of oil cans and motor parts that lay heaped against the eastern wall. He marked the gaze of his mother, whose stare seemed frozen to the line. He knew it as a gaze to be avoided, for it was relentless, dangerous somehow. He moved slowly, trying not to draw attention to himself, hunching his shoulders until he found a niche in the piles. Then he squatted, silently, his back to the wall. Later, the older boy came in. He too sidestepped the mother's staring down the line, and clapped earth angrily from his gloves. The mother suddenly looked at him. "Shush!" she cried. Then her gray eyes settled and fixed again on the hne. The older boy stepped past the younger, and into the kitcnen, where he sat to one side of the line in a broken chair. Soon his eyes closed, though he sat straight-backed, and his breathing mixed with the rustling of leaves in the woods outside the open window. The mother tried not to remember. That was trouble: mines, falling wellcasings , the old car that caught fire on the road to Forrest, the two dead at birth. 53 But memories paced the edges of her mind like skinny coon dogs with the mange, woods-hounds, lean and whining , with dull copper eyes. She could smell them there, at the edge, and she hated again the smell. To get rid of it she gripped the line tighter. Down Broomstick, the husband dug the grave. He had sent the older boy home. Why, he didn't know. Things happen. He dug next to the two stones of the others. They were small stones, sad. He did not turn from them. The price to pay, he thought. His spade rang against a rock, then slipped off into clay. He leaned on it, pushing, and the earth wedged out and he piled it next to the hole. He looked up from his work now and then to see the creek through the quaking aspens and poplars, and then down again, to the darkness that squared and deepened before him. The price to The mother, still holding the line with her mind, thought of her father. He had worn the green pants the day he died. She had hung them over the rail behind the barn a hundred washing days. Her mother had sewn them from some heavy cloth she'd bought at Sistersville, and he had worn them on important days. He had voted in them. He had worn them the day she was born. He had applied for the job with the well rigging company in them. And then he had worn them to town that day. There had been no blood on them. The bullet had pierced cleanly to the heart and he had fallen... 2ff7e9595c
