ACKING-DENSITY variations in a powder compact often P result in nonuniform shrinkages andor cracking during subsequent drying and sintering. In case of dry-pressed compacts, the effect of consolidation conditions on density variations has been sufficiently detailed by theoretical models.' However, although recent trends have favored the use of colloidal consolidation methods in order to attain ...

i r d L t t l t U c b NTRODUCTION n this case, we describe a 22-year-old man who has struggled ith a diagnosis of asthma and cough for seven years. Although is conventional care has been exemplary, his quality of life is acking, and he is plagued by persistent cough, limitation of his hysical activities, poor sleep, and adverse effects of his mainteance medications. His response to integrative ...

PURPOSE Appendiceal mucocele as a cystic dilatation filled with mucinous material is a very rare disease of the appendix vermiformis. Its preoperative diagnosis is still acking behind common use of imaging techniques. METHODS Retrospective analysis of the patients with a pathological diagnosis of appendiceal mucocele with regard to clinical and imaging features. RESULTS The study group incl...

In this contribution we focus on the calibration of very long image sequences from a hand-held camera that samples the viewing sphere of a scene. View sphere sampling is important for plenoptic image-based modeling approaches that try to capture the appearance o f a s c ene by storing images from all possible directions. The plenoptic approach is appealing since it allows in principle fast scen...

A new electromigration method for the separation of isotopes is described. This method ba ed on the pririciple of setting up a flow of electrol yte tlu'ough a packed column in a direction counttlJ"current to the flow of the i otopic ions being separated and at a rate intermediate between the velocities of these ions. Under these conditions, the faster moving ions will make headway against t he ...

Abasi et al. (2014) introduced the following two problems. In r -S imple k -P ath problem, given a digraph G on n vertices and positive integers , decide whether has an -simple -path, which is walk where every vertex occurs at most times total number of occurrences . ( )-M onomial D etection arithmetic circuit that succinctly encodes some polynomial P variables monomial degree each variable obt...

Many systems can be modeled with hard and various size spheres, therefore packing and geometrical structures of such sets are of great importance. In this paper, rigid spherical particles distributed in different sizes are randomly packed in confined spaces, using a parallel algorithm. Mersenne Twister algorithm was used to generate pseudorandom numbers for initial coordination of particles. Di...

Sign recognition is an integral part of autonomous cars. Any misclassi€cation of trac signs can potentially lead to a multitude of disastrous consequences, ranging from a life-threatening accident to even a large-scale interruption of transportation services relying on autonomous cars. In this paper, we propose and examine realistic security aˆacks against sign recognition systems for Deceivin...

have read with interest the article published in the iconoraphic section of this Journal by Drs. Diez-Lage and González nd titled The enigmatic eye of Nefertiti.1 After publishing a eview on the topic in the February issue of the British Journal f Ophthalmology,2 I would like to make a few comments. Queen Nefertiti (c. 1370–1330 AC) was the Great Royal Wife f Akhenaton (Amenhotep or Amenophis I...

The relationship between the bioavailability of dissolved organic matter (DOM) and its bulk chemical composition was examined on three dates at 10 sites on the Ogeechee River, a blackwater river in Georgia, Samples of riverine DOM were concentrated from filtered river water using reverse osmosis. In addition, particulate organic matter (POM), in the form of leaf litter, algae, and macrophytes, ...
