Fél évszázada, 1971 nyarán használták az első, ember vezette járművet a Hold felszínén. A következő évben további két, ugyanolyan jármű is érkezett Holdra. Az elmúlt időszakban több robotjármű eljutott és feladatot hajtott végre Holdon, közelmúltban már Marson megkezdődött kutatótevékenység. félévszázados évforduló alkalmából felidézzük idegen égitestekre eddig járművek történetét, magyar vonat...

The testicular vein exhibits variations in number, course, and insertion. Such differences may enhance the risk of varicocele complication patients by impairing drainage. following is a case report abnormal drainage right (RTV) draining into renal (RRV). incidence, insertion, termination angle veins were measured with 150 mm digital Vernier dial microcaliper, photographs taken Canon EOS 70D usi...

Left renal vein (LRV) compression can cause chronic pain and disability. autotransplantation (LR-AT) is an accepted method of treatment. artery denervation LRV decompression (LR-DD) a novel technique that addresses the issues with compression, hypertension left kidney innervation. We aim to compare postoperative outcomes, including impact on quality life (QoL), both surgical interventions. This...

This paper presents LRU-SP, a size-adjusted and popularity-aware extension to Least Recently Used (LRU) for caching web objects. The standard LRU, focusing on recently used and equal sized objects, is not suitable for the web context because web objects vary dramatically in size and the recently accessed objects may possibly differ from popular ones. LRU-SP is built on two LRU extensions, namel...

We give a presentation of the construction of motivic integration, that is, a homomorphism between Grothendieck semigroups that are associated with a first-order theory of algebraically closed valued fields, in the fundamental work of Hrushovski and Kazhdan [12]. We limit our attention to a simple major subclass of V -minimal theories of the form ACVF S , that is, the theory of algebraically cl...

The permutation flow shop problem (PFSSP) is an NP-hard problem of wide engineering and theoretical background. In this paper, a biogeography based optimization (BBO) based on memetic algorithm, named HBBO is proposed for PFSSP. Firstly, to make BBO suitable for PFSSP, a new LRV rule based on random key is introduced to convert the continuous position in BBO to the discrete job permutation. Sec...

Nutcracker syndrome (NCS) refers to the compression of left renal vein (LRV) between aorta and superior mesenteric artery that leads chronic pain. The causes an outflow obstruction leading venous hypertension which development tributaries, pelvic lumbar reflux. Diagnostic hilar nerve blocks have been performed successfully alleviate pain associated with NCS. Herein, we present initial midterm r...

Space-time codes have been designed over the last decade to enhance the reliability of open-loop fading wireless systems. However, recent technological advances have enabled the possibility of low-rate feedback from the receiver to the transmitter. The focus of this work is on the implications of this feedback in a point-to-point MIMO system with a coherent receiver and a general model for spat...
