Birds in rocky habitats of the Tatra Mountains (Carpathians)： species diversity and multiple ecological relationships

引用

Journal of Mountain Science 2016年第6期13卷 1078-1084页

作者： Michal CIACH filip kOWALSkI Department of Forest Biodiversity Institute of Forest Ecology and SilvicultureFaculty of ForestryUniversity of Agricultureal.29 Listopada 4531-425 KrakowPoland

Rocky habitats are regarded as biodiversity hot-spots. Along with high species diversity, diverse ecological relationships can be observed in these habitats. Large groups of bird species use rocks in various ways： as perching/roosting sites, breeding or foraging habitats, information exchange sites, display arenas or as sources of minerals and water. Because of the inaccessibility of these environments, their role and importance to animals has been underestimated. We evaluated the use of rocky habitats by birds in the Tatra Mountains （49°13′N; 19°57′E, Carpathians, central Europe）. Rocky habitats were used by 29 bird species, eight of which used cliffs directly （i.e. for nesting, foraging or resting）. The number of species recorded as using cliffs was correlated with the surface area of the cliff face. A total of 2o forms of rocky habitat use were recorded, in five behavioural categories： vocalization, foraging, perching, flight and nesting. Prevailing behaviours were flying by a rock face, circling above the face, and vocalization on a tree/shrub growing next to a rock. Rocks provide a nesting habitat for specialized petrophilic species and permit the existence of numerous ecological relations between species and habitats. The results of this study show that rocky habitats support the diversity of ecological relationships.

Adaptive slices for acquisition of anisotropic BRDF

引用

Computational Visual Media 2018年第1期4卷 55-69页

作者： Radomfr Vavra Jiri filip Institute of Information Theory and Automation of the CAS Pod Vodarenskou vezi4185 08Praha 8Czech Republic

BRDF continues to be used as a fundamental tool for representing material appearance in computer graphics. In this paper we present a practical adaptive method for acquisition of anisotropic BRDF, based on sparse adaptive measurement of the complete four-dimensional BRDF space by means of one-dimensional slices, which form a sparse fourdimensional structure in the BRDF space, and can be measured by continuous movements of a light source and sensor. Such a sampling approach is advantageous especially for gonioreflectometer-based measurement devices where the mechanical travel of a light source and a sensor imposes a significant time constraint. In order to evaluate our method, we have performed adaptive measurements of three materials and we simulated adaptive measurements of thirteen others. This method has one quarter the reconstruction error of that resulting from regular non-adaptive BRDF measurements using the same number of measured samples. Our method is almost twice as good as a previous adaptive method, and it requires from two to five times fewer samples to achieve the same results as alternative approaches.

Image-based appearance acquisition of effect coatings

Paint manufacturers strive to introduce unique visual effects to coatings in order to visually communicate functional properties of products using value-added, customized design. However, these effects often feature complex, angularly dependent, spatiallyvarying behavior, thus representing a challenge in digital reproduction. In this paper we analyze several approaches to capturing spatially-varying appearances of effect coatings. We compare a baseline approach based on a bidirectional texture function(BTF) with four variants of half-difference parameterization. Through a psychophysical study, we determine minimal sampling along individual dimensions of this *** conclude that, compared to BTF, bivariate representations better preserve visual fidelity of effect coatings, better characterizing near-specular behavior and significantly the restricting number of images which must be captured.

Pancreatic Castleman disease treated with laparoscopic distal pancreatectomy

引用

Hepatobiliary & Pancreatic Diseases International 2013年第3期12卷 332-334页

BACkGROUND: Castleman disease is an uncommon lympho-proliferative disorder most frequently occurring in the mediastinum. Abdominal forms are less frequent, with pancreatic localization of the disease in particular being extremely rare. Only seventeen cases have been described in the world literature. METHOD: This report describes an interesting and unusual case of pancreatic Castleman disease treated with laparoscopic resection. RESULTS: A 48-year-old woman presented with epigastric pain. CT scan showed a well-encapsulated mass on the ventral border of the pancreas. Endosonography with fine needle aspiration biopsy was performed. Biopsy showed lymphoid elements and structures of a normal lymph node. The patient was treated with laparoscopic distal pancreatectomy. The pancreas was transected with a Ligasure device and the pancreatic stump was secured with a manual suture. One year after surgery the patient was complaint-free and showed no signs of recurrence of the disease. CONCLUSIONS: Laparoscopic distal pancreatectomy is a feasible and safe method for the treatment of lesions in the body and tail of the pancreas. Transection of the pancreas with a Ligasure device offers the advantages of low bleeding and low risk of pancreatic fistula.
