Insect antiviral immunity primarily relies on RNAi mechanisms.While a key role of small interfering (si)RNAs and AGO proteins has been well established in this regard, the situation for PIWI All Purpose Cleaning Brushes proteins and PIWI-interacting (pi)RNAs is not as clear.In the present study, we investigate whether PIWI proteins and viral piRNAs
Observation of a single protein by ultrafast X-ray diffraction
Abstract The idea of using ultrashort X-ray pulses to obtain images of single proteins frozen in time has fascinated and inspired many.It was one of the arguments for building X-ray free-electron lasers.According to theory, the extremely intense pulses provide sufficient signal to dispense with using crystals as an amplifier, and the ultrashort pul
Scheduling preemptable jobs on identical processors under varying availability of an additional continuous resource
In this work we consider a problem of scheduling preemptable, independent jobs, characterized by the fact that their processing speeds depend on the amounts of a continuous, renewable resource allocated to jobs at a time.Jobs are scheduled on parallel, identical machines, with the criterion of minimization of the schedule length.Since two categorie
Efficient electron-induced removal of oxalate ions and formation of copper nanoparticles from copper(II) oxalate precursor layers
Copper(II) oxalate grown on carboxy-terminated self-assembled monolayers (SAM) using a step-by-step approach was used as precursor for the electron-induced synthesis of surface-supported copper nanoparticles.The precursor material Honey was deposited by dipping the surfaces alternately in ethanolic solutions of copper(II) acetate and oxalic acid wi
