Spotlight synthetic aperture radar (SAR) is a proven technique, which can provide high-resolution images as compared to those produced by traditional stripmap SAR. This paper addresses a high-resolution SAR focusing experiment based on Gaofen-3 satellite (GF-3) staring data with about 55 cm azimuth resolution and 240 MHz range bandwidth. In staring spotlight (ST) mode, the antenna always illuminates the same scene on the ground, which can extend the synthetic aperture. Based on a two-step processing algorithm, some special aspects such as curved-orbit model error correction, stop-and-go correction, and antenna pattern demodulation must be considered in image focusing...

In water-quality, early warning systems and qualitative detection of contaminants are always challenging. There are a number of parameters that need to be measured which are not entirely linearly related to pollutant concentrations. Besides the complex correlations between variable water parameters that need to be analyzed also impairs the accuracy of quantitative detection. In aspects of these problems, the application of least-squares support vector machines (LS-SVM) is used to evaluate the water contamination and various conventional water quality sensors quantitatively...

Environmental cofactors alter host-pathogen interactions and influence disease dynamics by impairing host resistance and/or increasing pathogen virulence. Terrestrial runoff is recognized as a major threat to coral reef health. However, the direct links between runoff and coral disease are not clear. Montipora white syndrome (MWS) is a coral disease that occurs in the Hawaiian archipelago, can be caused by various bacterial pathogens, including Vibrio species, and is linked to conditions associated with heavy rainfall and runoff...

Photodynamic therapy (PDT) is an oxygen-dependent light-triggered non-invasive therapeutic method showing many promising aspects in cancer treatment. For effective PDT, nanoscale carriers are often needed to realize tumor-targeted delivery of photosensitizers, which ideally should further target specific cell organelles that are most vulnerable to reactive oxygen species (ROS). Secondly, as oxygen is critical for PDT-induced cancer destruction, overcoming hypoxia existing in majority of solid tumors is important for optimizing PDT efficacy...

In the context of the White Book of Physical and Rehabilitation Medicine (PRM) in Europe, this paper deals with a global overview of the role of PRM in healthcare systems in Europe. Several documents and reports by WHO and the UN call for the worldwide strengthening of rehabilitation as a key health strategy of the 21st century. Therefore, further implementation of PRM in healthcare systems is crucial. Many aspects need to be considered when implementing PRM in a health system. Since PRM should be provided along the whole continuum of care, a specific phase model has been developed...

The spontaneous folding of flat gel films into tubes is an interesting example of self-assembly. Typically, a rectangular film folds along its short axis when forming a tube; folding along the long axis has been seen only in rare instances when the film is constrained. Here, we report a case where the same free-swelling gel film folds along either its long or short axis depending on the concentration of a solute. Our gels are sandwiches (bilayers) of two layers: a passive layer of cross-linked N,N'-dimethylyacrylamide (DMAA) and an active layer of cross-linked DMAA that also contains chains of the biopolymer alginate...

The issue of quality of life, particularly of patients affected by cancer, is very controversial, especially with adolescent patients who have no prospects of recovery. This article aims to describe the psychological mechanisms, which affect teenage patients with terminal cancer, in order to allow the best quality of life possible. The adaptation of teenager patients suffering from terminal illnesses is also related to other non-medical issues such as psychological, legal and ethical considerations. A correct and balanced communication with such patients is needed, in order of maintaining a positive mental approach ("hope") so that the teens are able to come to terms with the hard reality...

A curious aspect of the evolution of the hypnozoite theory of malarial relapse is its transmogrification from theory into 'fact', this being of historical, linguistic, scientific and sociological interest. As far as it goes, the hypnozoite explanation for relapse is almost certainly correct. I contend, however, that many of the genotypically homologous, non-reinfection, relapse-like Plasmodium vivax recurrences that researchers ascribe to hypnozoite activation are probably hypnozoite-independent. Indeed, some malariologists are starting to recognize that homologous P...

Limited research has examined the factors related to knowledge of gestational weight gain (GWG) recommendations and the receipt of advice from healthcare providers regarding GWG recommendations among women with pre-pregnancy overweight/obesity. Women with pre-pregnancy overweight/obesity (N = 191) reported the amount of gestational weight they believed they should gain and that healthcare providers advised them to gain. Only 24% (n = 46) of women had a correct knowledge of GWG recommendations. Women were less likely to have a correct knowledge of GWG recommendations if they had pre-pregnancy obesity, were of a minority race, or were socioeconomically disadvantaged...

OBJECTIVE: Temporal variations in the occurrence of out-of-hospital cardiac arrest (OHCA) have been shown. Most previous studies have in common that they include individuals whom have received cardiopulmonary resuscitation (CPR) and thus excluding a great number of all the actual cases of OHCA when conducting a study. Therefore the aim of this study was to describe temporal variations of OHCA, regardless of whether CPR was performed or not. DESIGN: All individuals aged 25-74 years in northern Sweden, 1989-2009, who suffered an out-of-hospital cardiac arrest with validated myocardial infarction aetiology (OHCA-V), regardless of whether CPR was performed or not, were included in this study, which resulted in 3357 individuals...

AIM: To explore the use of a rehabilitation-focused behavioral mapping method to identify changes in patient physical activity, location, and social interaction following the relocation of a rehabilitation ward. BACKGROUND: Rehabilitation wards are unique healthcare environments where patient activity is encouraged to improve recovery. Little is known about the impact of building design on patient behavior within a rehabilitation setting. We examined this issue when a rehabilitation ward was relocated without altering other aspects of the healthcare service...

Chronic heart failure is a progressive disease with an increasing prevalence. In spite of all medical progress (or thanks to it), it is finally one of the most common causes of death. Palliative care is an approach aimed to improve the quality of life of patients and their families in cases of life-threatening illness. Therefore, the use of palliative care in cardiology is entirely relevant. Estimating the course and prognosis of a patient with chronic heart failure is difficult despite many prognostic tools...

Self-supporting care is an emerging concept in the geriatric care system of Taiwan. The traditional care model tends to prioritize aspects such as "safety" and "convenient and effective". For older adult patients, this situation has led to excessive restrictions, enforced bedrest, and the use of adult diapers, which seriously deteriorate quality of life. The present article introduces the development and current status of self-supporting care and international empirical research results from the perspective of holistic care for older adults as well as describes the intervention strategies that are currently used in Taiwan...

Retinal first-order neurons, photoreceptors, receive visual inputs and convert them to neural signals. The second-order neurons, bipolar cells then sort out the visual signals and encode them through multiple neural streams. Approximately 15 morphological types of bipolar cells have been identified, which are thought to encode different aspects of visual signals such as motion and color (Ichinose et al. J Neurosci 34(26):8761-8771, 2014; Euler et al. Nat Rev Neurosci 15(8):507-519, 2014). To investigate functional aspects of OFF bipolar cells, single cell recordings are preferred; however, bipolar cells in the mouse retina are small and hard to distinguish from other types of cells...
