Drug molecules consist of a few tens of atoms connected by covalent bonds. How many such molecules are possible in total and what is their structure? This question is of pressing interest in medicinal chemistry to help solve the problems of drug potency, selectivity, and toxicity and reduce attrition rates by pointing to new molecular series. To better define the unknown chemical space, we have...
The Gram-positive, spore-forming bacterium Paenibacillus larvae (P. larvae) is the causative agent of the epizootic American Foulbrood (AFB), a fatal brood disease of the western honey bee (Apis mellifera). AFB is one of the most destructive honey bee diseases since it is not only lethal for infected larvae but also for the diseased colonies. Due to the high impact of honey bees on ecology and ...
The activation point of a button is defined as the depth at which it invokes a make signal. Regular buttons are activated during the downward stroke, which occurs within the first 20 ms of a press. The remaining portion, which can be as long as 80 ms, has not been examined for button activation for reason of mechanical limitations. The paper presents a technique and empirical evidence for an ac...
We investigate the pressing down game and its relation to the Banach Mazur game. In particular we show: Consistently relative to a supercompact, there is a nowhere precipitous normal ideal I on א2 such that player nonempty wins the pressing down game of length א1 on I even if player empty starts. For the proof, we construct a forcing notion to force the following: There is normal, nowhere preci...

The micro-injection upsetting (MIU) experiments of commercially pure aluminium have been conducted on two groups specimens with different grain structures. One group is coarse (CG, undeformed) and the other fine (FG) achieved via 4th pass equal channel angular pressing in micro-meso/scale. were further processed by micro/meso-scale extrusion before conducting MIU for fabricating tiny pins. Micr...
The aim was to investigate the feasibility of using a device characterize permeability in porous substrates with low gas flux. Al2O3 supports were prepared by dry pressing 1 3 wt% polyethylene glycol (PEG) as pore-forming agent. green body partially sintered at 1300 ºC. CO2 used measure both pressure loss and flux passing through substrate. behavior analyzed Darcy Forchheimer models. correlatio...
