Two possible “hairpin” secondary structures have been constructed. |
The two-dimensional technique on thin-layer plates has been used to fractionate intermediates in limited exonucleolytic digests of two dodekamers which could not be sequenced by conventional techniques. The potential general use of this method has been discussed.[Fatness and fat distribution by social stratum in Venezu... |
Adiposity and distribution of body fat are important issues in the prediction of degenerative diseases. Measurements of weight, height, circumferences of thigh, waist and hip; triceps, biceps, subscapular and suprailiac skinfolds; body mass index (BMI), centripetal index (CI), waist/hip (WHR), waist/thigh (WTR) ratios ... |
Since, for certain bounded signals, the common integral definition of the Hilbert transform may diverge, it was long thought that the Hilbert transform does not exist for general bounded signals. However, using a definition that is based on the H<sup>1</sup>-BMO(R) duality, it is possible to define the Hilbert transfor... |
Somatosensory evoked potential (SEP) latencies, motor and sensory nerve conduction velocities (CVs), and F-wave latenies were measured in 15 elderly normal subjects (mean age 74.1 years), and the results were used to derive indirect estimates of spinal cord CVs. These measurements were compared to those from 15 younger... |
1 The present study was designed to clarify the cellular mechanism through which the antihyperglycaemic drug, metformin, exerts its effects. For this purpose the contents of glucose transporter protein isoforms GLUT1 and GLUT4 were measured in plasma membrane and intracellular membrane fractions of skeletal muscle obta... |
The failure of CNS axons to regenerate following traumatic injury is due in part to a growth‐inhibitory environment in CNS as well as a weak intrinsic neuronal growth response. Olfactory ensheathing cell (OECs) transplants have been reported to create a favorable environment promoting axonal regeneration, remyelination... |
Dear Editor: The patient who has been mentioned in our paper entitled “ Coexistence of primary sarcomatoid carcinoma of the right ventricle and absence of right pulmonary artery”1 died on April 12, 2016. She had lived a full 2 years after surgery, and most patients who suffer from primary malignant cardiac tumor (PMCT)... |
An innovative three-story timber building, using self-centering, post-tensioned timber shear walls as the main horizontal load resisting system and lightweight non-composite timber-concrete floors, has recently been completed in Nelson, New Zealand. It is expected to be the trailblazer for similar but taller structures... |
On the occasion of the sixtieth anniversary of the Nuremberg Trials for Nazi war crimes, this essay explores the present-day significance of the tribunal in light of the current geopolitical situation and the policies of the Bush administration.

We perform growth of thin Al films using the electron cyclotron resonance (ECR) technique on {100} Si wafer and bcc {110} Nb thin films at room temperature. The {110} Nb thin films are also prepared by means of ECR. We carry out depositions using Xe plasma gas. We analyse the surface structure of the films using reflec... |
Atrial fibrillation is the most frequent rhythm disorder in elderly patients. Moreover, the risk of stroke and the bleeding risk under anticoagulant treatment are the highest in this population. Vitamin K antagonists were until now the reference treatment of the anticoagulant treatment and they demonstrated a net benef... |
Recent developments in the field of echocardiography have allowed us objectively quantify global and regional myocardial function. The first developed technology; tissue Doppler imaging provides a more objective assessment of myocardial function but it is subject to cardiac translational motion and passive tethering ef... |
Purpose – For many optimization problems such as optimal techniques, compositions, producing process, the optimizing objectives in systems are complex relations with respect to a great deal of parameters. Generally, the objective function is hardly obtained, even the searching objective is unquantifiable. So it is diff... |
Image restoration is a critical preprocessing step in computer vision, |
producing images with reduced noise, blur, and pixel defects. |
This enables precise higher-level reasoning as to the scene content in |
later stages of the vision pipeline (e.g., object segmentation, |
detection, recognition, and tracking). |
Restoration techniques have found extensive usage in a broad range of |
applications from industry, medicine, astronomy, biology, and |
photography. |
The recovery of high-grade results requires models of the image |
degradation process, giving rise to a class of often heavily |
underconstrained, inverse problems. |
A further challenge specific to the problem of blur removal is noise |
amplification, which may cause strong distortion by ringing artifacts. |
This dissertation presents new insights and problem solving procedures |
for three areas of image restoration, namely (1) model |
foundations, (2) Bayesian inference for high-order Markov |
random fields (MRFs), and (3) blind image deblurring |
(deconvolution). |
As basic research on model foundations, we contribute to reconciling |
the perceived differences between probabilistic MRFs on the one hand, |
and deterministic variational models on the other. |
To do so, we restrict the variational functional to locally supported finite |
elements (FE) and integrate over the domain. |
This yields a sum of terms depending locally on FE basis coefficients, |
and by identifying the latter with pixels, the terms resolve to MRF |
potential functions. |
In contrast with previous literature, we place special emphasis on robust |
regularizers used commonly in contemporary computer vision. |
Moreover, we draw samples from the derived models to further |
demonstrate the probabilistic connection. |
Another focal issue is a class of high-order Field of Experts MRFs |
which are learned generatively from natural image data and yield |
best quantitative results under Bayesian estimation. |
This involves minimizing an integral expression, which has no closed |
form solution in general. |
However, the MRF class under study has Gaussian mixture potentials, |
permitting expansion by indicator variables as a technical measure. |
As approximate inference method, we study Gibbs sampling in the |
context of non-blind deblurring and obtain excellent results, yet |
at the cost of high computing effort. |
In reaction to this, we turn to the mean field algorithm, and show |
that it scales quadratically in the clique size for a standard |
restoration setting with linear degradation model. |
An empirical study of mean field over several restoration scenarios |
confirms advantageous properties with regard to both image quality and |
computational runtime. |
This dissertation further examines the problem of blind deconvolution, |
beginning with localized blur from fast moving objects in the |
scene, or from camera defocus. |
Forgoing dedicated hardware or user labels, we rely only on the image |
as input and introduce a latent variable model to explain the |
non-uniform blur. |
The inference procedure estimates freely varying kernels and we |
demonstrate its generality by extensive experiments. |
We further present a discriminative method for blind removal of camera |
shake. |
In particular, we interleave discriminative non-blind deconvolution |
steps with kernel estimation and leverage the error cancellation |
effects of the Regression Tree Field model to attain a deblurring |
process with tightly linked sequential stages.Asymmetric viscoelastic flow through a porous channel with expanding or contracting walls: a model for transport of biological fluids through vessels |
In this article, the asymmetric viscoelastic fluid in a rectangular domain bounded by two porous moving channels with expanding or contracting walls is investigated.
