We report the most sensitive tests to date of the assumption of local position invariance (LPI) underlying general relativity, based on a 7 yr comparison of cesium and hydrogen atomic clocks (frequency standards). The latest results place an upper limit that is over 20 times smaller than the previous most sensitive tests; this is consistent with the null shift predicted by LPI. The result is ba...

We report the identification of a cDNA that encodes a putative protein of 94 amino acids and expected molecular weight of 10.7 kDa, the C-terminal half of which is identical to that of PEP19, a small, brain-specific protein involved in Ca++/calmodulin signaling. The novel rat-specific protein, tentatively named long PEP19 isoform (LPI), is the product of alternative splicing of the rat PCP4 gen...

The modern day Electronic Warfare(EW) receivers are required to match with the current day radar technologies like the Low Probability of Intercept(LPI) radars with various intra pulse modulations such as Chirp, Barker, Frank, Poly-phase and Poly time codes. This paper presents the state of the art single board Digital Receiver solution for intercepting and analyzing complex radar signals. Also...

A 59-year-old woman was seen by an ophthalmologist for blurred vision, ocular pain, headache, and nausea. She was diagnosed with acute primary angle closure (APAC) and successfully treated with medications. Using ultrasound biomicroscopy (UBM), engorged episcleral vein was observed and small uveal effusion was diagnosed after laser peripheral iridotomy (LPI). The uveal effusion disappeared and ...

To measure the Anterior Chamber depth, chamber angle with segment OCT and measuring intra ocular pressure before after Laser Peripheral Iridotomy in Primary Angle closure Disease. Methods: In primary patients both males females are selected variable ages. (AC) angles examined Gonioscopy configuration classified Shaffer System (1960) (1)The Intra Ocular Pressure (IOP) recorded applanation Tonome...

Photographs must be converted to halftone format when they are prepared for print reproduction. To faithfully reproduce an image using halftone dots, the proper resolution must be chosen to match the end use of the printed product as well as the attributes of the process and materials that will be used to reproduce the image. One of the important considerations when making a halftone is screen ...

I was pleased to see that my column inspired several articles in the popular media, including an upcoming article in Vogue magazine. My column also elicited feedback from my faculty colleagues and several LPI supporters around the country. One loyal donor from New York wrote me, “I do everything you do. So maybe that’s why I just passed my 95th birthday.” He continued, “Two things that I do tha...

This study aims to cluster countries according the logistics performance index (LPI) 2018 data. LPI is one of indicators for measuring sector based on a survey developed by World Bank since 2007 and has been widely accepted throughout world. There are 160 involved in organizing edition LPI. It helps understand their current position develop strategies policies improve world trade. Three cluster...

nowadays, in the modern wars, radars have faced with many threats. therefore, low probability of interception (lpi) capability is considered as an important factor in military radars. on the other hand, research on the interception of their signals is started and so far several methods are presented for detection of these signals. by using of time-frequency techniques, we can estimate signal pa...

To effectively combat the biodiversity crisis, we need ambitious targets and reliable indicators to accurately track trends measure conservation impact. In Canada, Living Planet Index (LPI) has been adapted produce a national indicator by both World Wildlife Fund-Canada (Canadian Index; C-LPI) Environment Climate Change Canada Species Index) provide insight into status of Canadian wildlife, eva...
