Macrophyte diversity-abundance relationship with respect to invasive and native dominants
Many experiments have demonstrated positive relationships between plant diversity and abundance, but few have examined the diversity-abundance relationship in non-experimental systems, aquatic systems, or in the presence of invasive (non-native dominant) species. We sampled the aquatic macrophyte community of a large lake in northern Wisconsin to examine: 1) the diversity-abundance relationship...


No Offense! On the Offense Principle and Some New Challenges
A central aim within criminal justice ethics is to give a plausible justification concerning which type of acts ought to be criminalized by the state. One of the principles of criminalization which has been presented and critically discussed in the philosophical literature is the Offense Principle. The primary aim of this paper is to argue that unless a rather special and implausible objective ...
Predictive parameters for return to pre-injury level of sport 6 months following anterior cruciate ligament reconstruction surgery
The aim of the study was to find predictive parameters for a successful resumption of pre-injury level of sport 6 months post anterior cruciate ligament (ACL) reconstruction. In a prospective study, 40 patients with a ruptured ACL were surgically treated with semitendinosus tendon autograft. Six months after surgery, strength of knee extensors and flexors, four single-leg hop tests, Anterior C...


Intraoperative anthropometric measurements of tibial morphology: comparisons with the dimensions of current tibial implants
This study analyzed morphological differences in the resected proximal tibial surfaces of Chinese males and females undergoing total knee arthroplasty (TKA) and compared the measurements with the dimensions of five currently used tibial implants. The mediolateral (ML), middle anteroposterior (AP), medial anteroposterior (MAP), and lateral anteroposterior (LAP) dimensions of the resected tibial ...
Prevention of pseudo-patella baja during total knee arthroplasty
Pseudo-patella baja (PPB) is a surgical complication that can arise from total knee arthroplasty and occurs when the patella tendon is not shortened but the level of the femorotibial joint line is elevated. The goal of this study was to assess the performance of a technique specifically designed to prevent the occurrence of PPB and its radiological results. Ninety-nine patients undergoing total...


Targeting histone methyltransferase EZH2 as cancer treatment
It is widely accepted that epigenetic alterations are associated with different stages of tumor formation and progression in many cancers. Therefore, epigenetic abnormalities in cancers are emerging as important biomarkers and may have therapeutic potential. The polycomb repressive complex 2 (PRC2) is a key epigenetic regulator that catalyzes tri-methylation of lysine 27 on histone H3 (H3K27me3...
Nonrigid registration improves MRI T2 quantification in heart transplant patient follow-up
To evaluate the use of a nonrigid registration technique for detecting acute heart transplant rejection by MRI T2 quantification. Myocardial T2 quantification was achieved in 279 consecutive examinations from 78 different patients. The protocol consisted of 10 successive black-blood fast spin echo sequences with varying echo times, and a postprocessing based on image registration and exponentia...

Artifact Reduction in Radiometric Compensation of Projector-Camera Systems for Steep Reflectance Variations
In this paper, we propose a novel radiometric compensation method that applies a high-spatial-resolution camera to a projector-camera system to reduce the artifacts around the regions where the reflectance of the projection surface changes steeply. The proposed method measures the reflection in the region of a single projector pixel on a projection surface with multiple camera pixels. From the ...
Spatiotemporal Group Context for Pedestrian Counting
Pedestrian counting has been a challenging topic, especially in video surveillance, for a long time due to the view variations, scale changes, and spatial occlusions. While most of the previous approaches try to count people within one frame, our approach addresses this problem with a group context model, which is to segment individuals into groups and model the spatiotemporal relationships bet...

Bandwidth Efficient and Rate-Adaptive Video Delivery in TV White Space
Video delivery in television white space (TVWS) is a challenging task due to the variation of the spectrum availability in TVWS and the stringent bandwidth requirements of video streaming. Most existing frameworks employ an opportunistic spectrum access style which result in bandwidth inefficiency since only one spectrum hole in TVWS can be used. In this paper, we propose a bandwidth efficient ...
Mobile Collaborative Video
The emergence of pico projectors as a part of future mobile devices presents unique opportunities for collaborative settings, especially in entertainment applications, such as video playback. By aggregating pico projectors from several users, it is possible to enhance resolution, brightness, or frame rate. In this paper we present a camera-based methodology for the alignment and synchronization...

Efficient Mode Decision Schemes for HEVC Inter Prediction
The emerging High Efficiency Video Coding (HEVC) standard reduces the bit rate by almost 40% over the preceding state-of-the-art Advanced Video Coding (AVC) standard with the same objective quality but at about 40% encoding complexity overhead. The main reason for HEVC complexity is inter prediction that accounts for 60%–70% of the whole encoding time. This pa...
Initialization, Limitation, and Predictive Coding of the Depth and Texture Quadtree in 3D-HEVC
The 3D video extension of High Efficiency Video Coding (3D-HEVC) exploits texture-depth redundancies in 3D videos using intercomponent coding tools. It also inherits the same quadtree coding structure as HEVC for both components. The current software implementation of 3D-HEVC includes encoder shortcuts that speed up the quadtree construction process, but those are always accompanied by coding l...
Fast Multiview Video Coding Using Adaptive Prediction Structure and Hierarchical Mode Decision
The multiview video coding (MVC) adopts hierarchical B picture prediction structure and offers many prediction modes to effectively remove the spatial, temporal, and inter-view redundancies inherited in multiview video (MVV), but at the price of extremely high computational complexity. To address this problem, a fast MVC method by jointly using adaptive prediction structure (APS) and hierarchic...
A Highly Efficient Compression Framework for Time-Varying 3-D Facial Expressions
The rapid recent development of 3-DTV technology has led to an increase in studies on mesh-based 3-D scene representation. Compressing 3-D time-varying meshes is critical for the storage and transmission of 3-D contents. This paper proposes a highly efficient framework for compressing time-varying 3-D facial expressions. We use the near-isometric property of human facial expressions to paramete...
