The first “close encounter” between the fields of chemokines and HIV occurred in the late spring of 1995, when my group at NCI’s Laboratory of Tumor Cell Biology (LTCB) received from Harvard Microchemistry and Proteomics the amino acid sequences of three peptide fragments from an HPLC-purified fraction that we had submitted a few weeks earlier. The sequences showed a perfect match with the huma...

The history of global longline fishing illustrates the role of new technologies (e.g. vessel innovations, freezers, fishing gear), the expansion of fishing grounds, and the operational characteristics of the fleets (e.g. fleet sizes, fishing methods, product focus) in shaping today’s fishery. More recently, management regulations, the price of oil, the cost of labour, and market demand have als...

Introduction A Measles rubella campaign that targeted 9 months to 14 year old children was conducted in all the 47 counties in Kenya between 16th and 24th of May 2016. Micro-planning using an android phone-based app was undertaken to map out the target population and logistics in all the counties 4 weeks to the campaign implementation instead of 6 months as per the WHO recommendation. The outco...

The question, why warm water freezes faster than cold water is not new. In fact, it has been here for hundreds of years. In 1969 Erasto Mpemba observed the effect of paradoxical freezing in the preparation of ice cream. This phenomenon we today call Mpemba effect, but Mpemba is actually not its first explorer. First notices we find in Aristotle’s work Meteorologica from 350 B.C. Despite more th...

R are an evolutionarily ancient class of mobile genetic elements that transpose replicatively within their host genomes via RNA intermediates. There are three major retrotransposon groups, the Ty1-copia group and the gypsy group long terminal repeat (LTR) retrotransposons and the non-LTR retrotransposons or LINE elements (ref. 1; Fig. 1). All three groups are widespread in the eukaryotes, altho...

This paper describes the statistical analytics technology being developed to help K-12 public schools in New York City reduce the energy consumption. A multi-step statistical analysis procedure is proposed, to assess energy consumption and to identify energy saving opportunities for large portfolios of buildings such as the NYC K-12 public school buildings. The method borrows strength from and ...

The inhabitants of Cuba's capital, Havana, are using semipublic group chats on messaging applications such as WhatsApp and Telegram to access food, hygiene products, medication, other basic necessities during times scarcity. This has been especially prevalent the COVID-19 pandemic. Such chat groups created digital spaces in which locals swap scarce goods share vital information about availabili...

Continuous capacity modulation, for example by varying compressor speed, is only one alternative to conventional cycling of vapor compression systems. Cycling the compressor at higher frequencies (~0.01–0.1 Hz) than conventional systems (~0.001 Hz) offers a potentially simpler and less costly alternative. Experiments were conducted to quantify effects of steady vs. pulsed flow on the performanc...
