which is valid for any arbitrary volume, so the integrand is zero and we recover a classical continuity equation similar to that derived for mass conservation in hydrodynamics. (1) is the equivalent to a Lagrangian conservation of bird density with dρ/dt = 0, hence, a flock of birds traveling at speed U with an initial density ρn−1 = ρ(xn−1 + ǫ, tn−1) at the interface of patch Pn−1 at time tn−1...

We report a case of pleomorphic adenoma of the trachea in an 8-year-old boy who required emergency surgery for severe respiratory distress. Chest computed tomographic scan and bronchoscopy showed a relatively large mass in distal trachea and right main bronchus and destruction of the lung parenchyma. The patient was subjected to right carinal resection, pneumonectomy, and pericardial patch trac...

We report on a real-time application supporting fast, realistic real-time rendering of asteroid datasets, as well as collision detection and response between the asteroid and prototype robotic surface exploration vehicles. The system organizes the asteroid surface into a two-level multiresolution structure, which embeds a fine-grained perpatch spatial index within a coarse-grained patch-based s...

SEC15 function is required at a late stage of the yeast secretory pathway. Duplication of the gene encoding the ras-like, GTP-binding protein, Sec4, can suppress the partial loss of function resulting from the sec15-l mutation, but cannot suppress disruption of sec15. Analysis of the SEC15 gene predicts a hydrophilic protein product of 105 kD. Anti-Sec15 antibody recognizes a protein of 116-kD ...

Proof of Lemma 1: In order to characterize the equilibrium, we first start with the second period decisions for the consumers who purchased the product in the first period. If, in the second period, no vulnerabilities arise then there is no decision to make for a consumer. Suppose a vulnerability arises. If a consumer with valuation v decides to patch the software, her expected total payoff is ...

Metastatic masses in the kidney are rare, and metastasis of pancreatic adenocarcinoma to the kidney is even rarer. A 58-year-old male patient with macroscopic hematuria presented to the emergency department. Abdominopelvic computed tomography revealed a lesion that was not visualized as a complete mass but instead appeared as a patch extending from the pelvis to the parenchyma. Biopsy indicated...

BACKGROUND Sweat testing is a noninvasive technique for monitoring drug exposure in treatment, criminal justice, and employment settings. METHODS We evaluated cocaine excretion in 9 participants' sweat after they received 3 low doses (75 mg/70 kg) of cocaine HCl subcutaneously within 1 week and, 3 weeks later, 3 high doses (150 mg/70 kg). Six additional participants completed portions of the ...

A 21-year-old woman with a painful chest wall mass was found to have a parachordoma (PC). The tumor arose from the ®fth intercostal space. A wide chest wall resection including the tumor and a 2.5 cm free margin and the subsequent reconstruction with a Gore-Tex soft tissue patch covered with a latissimus dorsi rotational ̄ap was performed. To our knowledge, chest wall parachordoma has not been ...

Context. An intriguing silhouette of a small dust patch can be seen against the disk S0 galaxy NGC 3269 in Antlia cluster optical images. The images do not provide any clue as to whether is local Jupiter mass-scale cloudlet or large extragalactic complex. Aims. We aim resolve nature this object: it Galactic an complex? Methods. ALMA and APEX spectroscopy Gemini GMOS long-slit were used measure ...
