The restoration might occur trillions of years from now, when every object down to the smallest particle has expanded out of causal contact with every other object, making the universe as good as empty, and perfectly symmetrical under translations, rotations, dilatations, and special conformal transformations.

There was no history of abnormalities or genetic disorders in previous children in the family. Gestational diabetes during the pregnancy did not cause any significant complications. Feeding difficulties and recurrent vomiting began to occur at six weeks, resulting in severe weight loss. The girl received surgery and repeated balloon dilatations by the age of two for severe achalasia.

YaDICs is a program written to perform digital image correlation on 2D and 3D tomographic images. The program was designed to be both modular, by its plugin strategy and efficient, by it multithreading strategy. It incorporates different transformations (Global, Elastic, Local), optimizing strategy (Gauss-Newton, Steepest descent), Global and/or local shape functions (Rigid- body motions, homogeneous dilatations, flexural and Brazilian test models)...

Magnetic resonance cholangiopancreatography (MRCP) of Caroli disease, showing cystic dilatations of bile ducts. Modern imaging techniques allow the diagnosis to be made more easily and without invasive imaging of the biliary tree. Commonly, the disease is limited to the left lobe of the liver. Images taken by CT scan, X-ray, or MRI show enlarged intrahepatic (in the liver) bile ducts due to ectasia.

A portocaval anastomosis is a specific type of anastomosis that occurs between the veins of the portal circulation and those of the systemic circulation. The inferior end of the esophagus and the superior part of the rectum are potential sites of a harmful portacaval anastomosis. In portal hypertension, as in the case of cirrhosis of the liver, the anastomoses become congested and form venous dilatations. Such dilatation can lead to esophageal varices and anorectal varices.

Urethroplasty is the repair of an injury or defect within the walls of the urethra. Trauma, iatrogenic injury and infections are the most common causes of urethral injury/defect requiring repair. Urethroplasty is regarded as the gold standard treatment for urethral strictures and offers better outcomes in terms of recurrence rates than dilatations and urethrotomies. It is probably the only useful modality of treatment for long and complex strictures though recurrence rates are higher for this difficult treatment group.

Physics part 1 Resnick/Halliday p. 5. Fizeau was involved in the discovery of the Doppler effect, which is known in French as the Doppler–Fizeau effect. In 1853, Fizeau described the use of the capacitor (sometimes called a "condenser") as a means to increase the efficiency of the induction coil. Later on, he studied the thermal expansion of solids and applied the phenomenon of interference of light to the measurement of the dilatations of crystals.

Phase contrast MRI is one of the main techniques for magnetic resonance angiography (MRA). This is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities. MRA is often used to evaluate the arteries of the neck and brain, the thoracic and abdominal aorta, the renal arteries, and the legs (the latter exam is often referred to as a "run-off").

Closure of the umbilical artery by vasoconstriction consists of multiple constrictions which increase in number and degree with time. There are segments of dilatations with trapped uncoagulated blood between the constrictions before complete occlusion. Both the partial constrictions and the ultimate closure are mainly produced by muscle cells of the outer circular layer. In contrast, the inner layer seems to serve mainly as a plastic tissue which can easily be shifted in an axial direction and then folded into the narrowing lumen to complete the closure.

Nor does it have an otolith, a sensory organ connected with balance, which the former possesses. Molgula occulta hatches into a tailless larva from the chorion in twelve hours and develops four ampullae or dilatations immediately before metamorphosing into a juvenile. It appears that the tailed larva is the ancestral state in the Molgulidae and that loss of the tail has occurred on at least four separate occasions independently. Without tail or otolith, the larva is unable to swim or orient itself and so is unable to disperse to new locations.

The hepatopulmonary syndrome results from the formation of microscopic intrapulmonary arteriovenous dilatations in patients with both chronic and far less common, acute liver failure. The mechanism is unknown but is thought to be due to increased liver production or decreased liver clearance of vasodilators, possibly involving nitric oxide. The dilation of these blood vessels causes overperfusion relative to ventilation, leading to ventilation- perfusion mismatch and hypoxemia. There is an increased gradient between the partial pressure of oxygen in the alveoli of the lung and adjacent arteries (alveolar-arterial [A-a] gradient) while breathing room air.

The surrounding mesocardium degenerates to leave the primitive heart attached only by its arterial and venous ends, which are anatomically fixed to the pharyngeal arches and the septum transversum, respectively. The developing tubular heart then folds ventrally and bulges in five regions along its length: the first one and closest to the arterial end is the truncus arteriosus, then follow the bulbus cordis, the primitive ventricle, the primitive atrium and the sinus venosus. All five embryonic dilatations of the primitive heart develop into the adult structures of the heart.

In 1877, he defended his doctoral thesis, and during the following year received his agrégation with a dissertation titled "Les hypertrophies et les dilatations cardiaques indépendante des lésions valvulaires". In the late 1870s, with Charles-Émile François-Franck, he performed studies on the excitation of the cerebral cortex and the localization of brain function.Complete Record - Heirs of Hippocrates No. 2127 Afterwards, he returned to Bordeaux, where from 1881 to 1919, he was to the chair of pathology. Pitres died in 1928, at the age of 79, after falling down stairs.

The aortic root is the portion of the aorta beginning at the aortic annulus and extending to the sinotubular junction. It is sometimes regarded as a part of the ascending aorta, and sometimes regarded as a separate entity from the rest of the ascending aorta. Between each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses. The sinotubular junction is the point in the ascending aorta where the aortic sinuses end and the aorta becomes a tubular structure.

In order to research emotional responses to art, researchers often rely on behavioral data. But new psychophysilogical methods of measuring emotional response are beginning to be used, such as the measurement of pupillary response. Pupil responses have been predicted to indicate image pleasantness and emotional arousal, but can be confounded by luminance, and confusion between an emotion's positive or negative valence, requiring an accompanying verbal explanation of emotional state. Pupil dilatations have been found to predict emotional responses and the amount of information the brain is processing, measures important in testing emotional response elicited by artwork.

Dissection of human embryo The cephalic end of the neural groove exhibits several dilatations that, when the tube is closed, assume the form of the three primary brain vesicles, and correspond, respectively, to the future forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon) (Fig. 18). The walls of the vesicles are developed into the nervous tissue and neuroglia of the brain, and their cavities are modified to form its ventricles. The remainder of the tube forms the spinal cord (medulla spinalis); from its ectodermal wall the nervous and neuroglial elements of the spinal cord are developed, while the cavity persists as the central canal.

If x, y \in T(S) and the Teichmüller mapping between them has dilatation K then the Teichmüller distance between them is by definition \frac12 \log K. This indeed defines a distance on T(S) which induces its topology, and for which it is complete. This is the metric most commonly used for the study of the metric geometry of Teichmüller space. In particular it is of interest to geometric group theorists. There is a function similarly defined, using the Lipschitz constants of maps between hyperbolic surfaces instead of the quasiconformal dilatations, on T(S) \times T(S), which is not symmetric.

The terms "Tarlov cyst" or "sacral perineural cyst" refer to cystic lesions of the spinal meninges with innervation as well as nerve sheath dilatations with subarchnoid communication. While they were once thought to be a histopathological finding, they can be radiologically confirmed by specialized time lapsed MRI and CT imaging techniques showing subarchnoid communication from the nerve fibers in the cysts. They can also be surgically verified when the nerve fibers are visualized in the cystic sac. Often the cysts cause erosion from enlargement, damaging vertebrae and discs and can be misdiagnosed as primary stenosis or disc herniation.

Success is less than 9% for the first or subsequent urethrotomies. Most patients will be expected to experience failure with longer followup and the expected long-term success rate from any urethrotomy approach is 0%. Beginning in 2003, several urology residency programs in the northeastern section of the United States began advocating the use of urethrotomy as initial treatment in the young stricture patient, versus urethral dilatation. It is theorized that the one-to-two years of relief from stricture disease will allow the practitioner and the patient to plan the most effective treatment regimen without having the concern that undergoing multiple dilatations cloud the judgment of the patient.

Magnetic resonance angiography Magnetic resonance angiography (MRA) generates pictures of the arteries to evaluate them for stenosis (abnormal narrowing) or aneurysms (vessel wall dilatations, at risk of rupture). MRA is often used to evaluate the arteries of the neck and brain, the thoracic and abdominal aorta, the renal arteries, and the legs (called a "run-off"). A variety of techniques can be used to generate the pictures, such as administration of a paramagnetic contrast agent (gadolinium) or using a technique known as "flow-related enhancement" (e.g., 2D and 3D time-of-flight sequences), where most of the signal on an image is due to blood that recently moved into that plane (see also FLASH MRI).

Penner's research began in the theory of train tracks including a generalization of Thurston's original construction of pseudo- Anosov maps to the so-called Penner-Thurston construction, which he used to give estimates on least dilatations. He then co-discovered the so-called Epstein-Penner decomposition of non-compact complete hyperbolic manifolds with David Epstein, in dimension 3 a central tool in knot theory. Over several years he developed the decorated Teichmüller theory of punctured surfaces including the so-called Penner matrix model, the basic partition function for Riemann's moduli space. Extending the foregoing to orientation-preserving homeomorphisms of the circle, Penner developed his model of universal Teichmüller theory together with its Lie algebra.

Before the neural groove is closed a ridge of ectodermal cells appears along the prominent margin of each neural fold; this is termed the neural crest or ganglion ridge, and from it the spinal and cranial nerve ganglia and the ganglia of the sympathetic nervous system are developed. By the upward growth of the mesoderm the neural tube is ultimately separated from the overlying ectoderm. The cephalic end of the neural groove exhibits several dilatations, which, when the tube is closed, assume the form of three vesicles; these constitute the three primary cerebral vesicles, and correspond respectively to the future fore-brain (prosencephalon), mid-brain (mesencephalon), and hind- brain (rhombencephalon). The walls of the vesicles are developed into the nervous tissue and neuroglia of the brain, and their cavities are modified to form its ventricles.

The first description of the anterior cricoid split appears in the early 1900s by Killian and the first description of the posterior cricoid split is credited to Galebsky in 1927. In 1938, Looper rotated the hyoid bone to augment a stenotic adult laryngeal fracture sustained in a railroad accident. In 1968, Lapidot used this principle in piglets to show that a flap of thyroid cartilage rotated on perichondrium to replace a segment of resected cricoid cartilage could survive, suggesting that laryngeal growth could continue after reconstruction without restenosis. Great advances in open airway reconstruction were made in the 1970s, many of which occurred in Toronto, Canada. In 1971, Fearon and Ellis described a child with severe subglottic stenosis who, after failed dilatations and anterior cricoid split with auricular cartilage graft augmentation, eventually underwent tracheotomy, placement of an anterior costal cartilage graft with buccal mucosa and a stent and was eventually decannulated.
