Due to their rich behaviors, pulse-coupled oscillator (PCO) networks have been widely studied. Prior research has focused on systems with excitatory, inhibitory, and mixed excitatory/inhibitory coupling, as well as on systems with and without delays in pulse transmission. This article focuses on PCO networks with delayed excitatory/inhibitory coupling. We consider a simple phase transition rule...

Pushdown systems (PDS) naturally model sequential recursive programs. Numeric data types also often arise in real-world programs. We study the extension of PDS with unbounded counters, which naturally model numeric data types. Although this extension is Turingpowerful, reachability is known to be decidable when the number of reversals between incrementing and decrementing modes is bounded. In t...

Purpose. To describe a reliable method of predicting native joint line and posterior condylar offset (PCO) using true lateral digital radiographs of the distal femur. Methods. PCO was measured relative to a line drawn parallel to the posterior cortex of the distal femur and the joint line was measured from the posterior condylar flare to the articular surface. A ratio was then calculated for th...

One hundred and twenty five patients with polycystic ovaries on ultrasonography and 17 controls with normal ovaries on ultrasound and regular ovulary cycles underwent clinical and endocrine evaluation. Of 125 ultrasound-diagnosed polycystic ovary patients (PCO) 49.6% complained about hirsutism, 55.2% had menstrual disturbances (46.4% oligomenorrhea, 8.8% amenorrhea), 23.2% had normal but irregu...

BACKGROUND We investigated the differences in anthropometrical, hormonal and insulin resistance parameters according to the subtype of polycystic ovary syndrome (PCOS) in Korean women. METHODS We recruited 166 women with PCOS and retrospectively recruited 277 controls. PCOS was diagnosed by irregular menstruation (IM), polycystic ovary (PCO) and hyperandrogenism (HA). Subjects were divided in...

REIVICH, MARTIN. Arterial Pcoz and cerebral hemodynamics. Am. J. Physiol. 206(1) : q-35. rg64.---The effect of arterial Pco:! in the control of cerebral hemodynamics over the full range of responsiveness of the cerebral vasculature was studied in the rhesus monkey. Cerebral perfusion pressure and arterial 02 saturation were controlled so that they produced no significant effect on the cerebral ...

this study was designed to determine the prevalence of bipolar disorder in women with polycystic ovarian syndrome (pco). one hundred and ten women with definite diagnosis of pco and one hundred and ten age-matched infertile women due to other reasons except for pco were enrolled in this case-control study. ten ml fasting venous blood sample obtained to measure fasting glucose, lh and fsh. heigh...

PURPOSE To evaluate whether inhibition of phosphorylated Akt (pAkt) would reduce or prevent posterior capsule opacification (PCO) in an ex vivo canine lens capsule model. METHODS Normal and cataractous lenses (n=6) were evaluated for pAkt via immunohistochemistry and immunoblotting. Primary cultures of lens epithelial cells (LEC) were exposed to ultraviolet light (UV) to induce pAkt. Cultures...

Aim. To compare the basic endocrine profile and outcomes of in vitro fertilization (IVF) in women with polycystic ovary syndrome (PCOS), ovulatory polycystic ovaries (PCO), or normal ovaries (NO). Methods. The basic clinical features and in vitro fertilization and embryo transfer outcome in patients receiving IVF or intracytoplasmic sperm injection (ICSI) were retrospectively analyzed. Results....

OBJECTIVE Traditionally, delivery room management of extremely low birth weight (ELBW) infants consisted of immediate intubation and mechanical ventilation. There have been recent reports of success using nasal prongs continuous positive airway pressure (NCPAP) in this population. Data on the partial pressure of carbon dioxide (PCO(2)) in spontaneously breathing ELBW infants is very limited. Th...
