Carin-ALN as proposed recently by Rouveirol and Ventos [2000] is an interesting new rule learning bias for ILP. By allowing description logic terms as predicates of literals in datalog rules, it extends the normal bias used in ILP as it allows the use of all quantified variables in the body of a clause, instead of the normal exist quantified variables and it has atleast and atmost restrictions ...

Aluminum nitride (AlN) hollow nanofibers were synthesized via plasma-enhanced atomic layer deposition using sacrificial electrospun polymeric nanofiber templates having different average fiber diameters (~70, ~330, and ~740 nm). Depositions were carried out at 200°C using trimethylaluminum and ammonia precursors. AlN-coated nanofibers were calcined subsequently at 500°C for 2 h to remove the sa...

Purpose. The aim of this study was to directly compare the efficacy and the safety of the two agents for postmenopausal women. Methods/Principal Findings. Electronic databases were searched for relevant articles that met our predefined inclusion criteria. Seven randomized controlled trials (RCTs) involving 4054 women were identified and included. Although Aln was more effective than Rlx in incr...

In order to increase the therapeutic effect of doxorubicin (DOX) on bone metastases, a multifunctional micelle was developed by combining pH-sensitive characteristics with bone active targeting capacity. The DOX loaded micelle was self-assembled by using doxorubicin-poly (ethylene glycol)-alendronate (DOX-hyd-PEG-ALN) as an amphiphilic material. The size and drug loading of DOX loaded DOX-hyd-P...

چکیده لایه های سطحی کامپوزیتی بر زیر لایه آلیاژ آلومینیمی aa6061 به کمک روش همزن اصطکاکی و با افزودن پودر در مقیاس نانومتری aln (با میانگین اندازه nm 60) به ناحیه خمیری شده سطحی از طریق شیار تعبیه شده در راستای حرکت طولی ابزار، ایجاد شد. به این منظور متغیرهای فرایند همزن اصطکاکی چون سرعت چرخش ابزار، سرعت پیشروی زیر لایه و تعداد پاس های عبوری تنظیم شدند تا لایه سطحی نانو کامپوزیت al/aln با ریز ...

In this work we investigate the synthesis of Bragg reflectors consisting either of AlN/GaN or of (Al,In)N/GaN by plasma-assisted molecular beam epitaxy (MBE). In addition, we study the impact of Si-doping on the surface morphology and the structural and electrical properties of AlN/GaN Bragg reflectors in order investigate the feasibility of obtaining vertically conducting Bragg mirrors. The st...

Several semiempirical tight-binding models are parametrized and tested for aluminum clusters and nanoparticles using a data set of 808 accurate AlN (N = 2-177) energies and geometries. The effects of including overlap when solving the secular equation and of incorporating many-body (i.e., nonpairwise) terms in the repulsion and electronic matrix elements are studied. Pairwise orthogonal tight-b...

Using epitaxial aluminum nitride (AlN) developed for ultraviolet photonics and high-speed electronics, we demonstrate suspended AlN thin-film bulk acoustic resonators (FBARs) at 9.2 GHz in the X-band (8–12 GHz) of microwave spectrum. The show a Qmax≈614 figure merit f⋅Q≈5.6 THz. material stack these epi-AlN FBARs allows monolithic integration with AlN/GaN/AlN quantum well high-electron-mobility...

Bisphosphonates such as alendronate and zoledronate are blockbuster drugs used to inhibit osteoclast-mediated bone resorption. Although the molecular mechanisms by which bisphosphonates affect osteoclasts are now evident, the exact route by which they are internalized by cells is not known. To clarify this, we synthesized a novel, fluorescently labeled analog of alendronate (AF-ALN). AF-ALN was...
