This paper presents a 1.9-ps 8× phase interpolation time-to-digital converter (PI-TDC). architecture enhances the resolution and conversion speed in cooperation with interpolation, high-frequency readout, reset techniques. The prototype PI-TDC is designed 65-nm CMOS process 1-V power supply, achieving at 2.5-GS/s. simulated DNL 0.85-LSB, INL 0.64-LSB. applied to high-speed time-based analog-to-...

The production cross-section of the $\chi_{c1}(3872)$ state relative to $\psi(2S)$ meson is measured using proton-proton collision data collected with LHCb experiment at centre-of-mass energies $\sqrt{s}=8$ and 13 TeV, corresponding integrated luminosities 2.0 5.4 fb$^{-1}$, respectively. two mesons are reconstructed in $J/\psi\pi^{+}\pi^{-}$ final state. ratios prompt nonprompt cross-sections ...

Background: Fungal corneal ulcer is the most dangerous and challenging type of infective keratitis.  Since most of the ophthalmic antifungal drops are scarce and expensive in developing countries, attempts have been made to study fungicidal property of some readily available antiseptic agents as a substitute.  Povidone iodine (PI) and chlorhexidine gluconate (CHx) has been postulated to be effe...

A dairy herd including approximately 50 milking cows and 40 heifers and calves was investigated. This herd was detected with high prevalence of calves persistently infected (PI) with bovine viral diarrhea virus (BVDV). Nine PI animals including a milking cow and 8 newborn calves were detected in the herd within 4 months. Prevalence of PI animals in this herd was estimated 7.0% which was very hi...

The alpha-1-antitrypsin (alpha 1 AT) Pi phenotypes have been determined by isoelectric focusing in a series of 228 patients having a histologically diagnosed malignant lymphoma and in 250 healthy controls. The Pi MZ phenotype occurred in 13 patients with lymphoma (5 . 8%) and in five of 250 healthy individuals (2%). Furthermore, one patient with a Pi SS and three patients with an abnormal unkno...

In patients with chronic pancreatitis (CP) the relation among exocrine pancreatic secretion, gastrointestinal hormone release, and motility is disturbed. We studied digestive and interdigestive antroduodenal motility and postprandial gut hormone release in 26 patients with CP. Fifteen of these patients had pancreatic insufficiency (PI) established by urinary para-aminobenzoic acid test and feca...

The present experiment examined whether discrimination learning shapes the single-peaked response distributions usually obtained with the peak procedure. Two sources of learning in pigeons were disclosed: learning to respond near the time of reinforcement on fixed interval (FI) trials and learning to withhold responding once the FI duration had elapsed on peak interval (PI) trials. Pigeons also...

We study the dynamics of corotational wave maps from $\mathbb R^{1+2} \rightarrow \mathbb S^2$ at threshold energy. It is known that topologically trivial with energy $< 8\pi$ are global and scatter to a constant map. In this work, we prove map equal $8\pi$ globally defined scatters in one time direction, other either scatters, or breaks down finite converges superposition two harmonic maps. Th...
