In this paper, a novel time-frequency signature using resonance-based sparse signal decomposition (RSSD), phase space reconstruction (PSR), time-frequency distribution (TFD) and manifold learning is proposed for feature extraction of ship-radiated noise, which is called resonance-based time-frequency manifold (RTFM). This is suitable for analyzing signals with oscillatory, non-stationary and non-linear characteristics in a situation of serious noise pollution. Unlike the traditional methods which are sensitive to noise and just consider one side of oscillatory, non-stationary and non-linear characteristics, the proposed RTFM can provide the intact feature signature of all these characteristics in the form of a time-frequency signature by the following steps: first, RSSD is employed on the raw signal to extract the high-oscillatory component and abandon the low-oscillatory component...

Sialolithiasis is one of the most common and extensively obstructive disorders of the major salivary glands. Here, we report 3 cases of sialolithiasis in the submandibular salivary gland showing symptomatic similarities to other dental and non-dental disorders of the maxillofacial area. How the various clinical features of this condition and findings on 3D-CT may lead to a misdiagnosis are also discussed. In the first case, that of a 45-year-old woman, a final diagnosis of a non-radiopaque submandibular sialolith allowed the initially indicated surgical extraction of a malerupted and semi-impacted right mandibular 3rd molar to be abandoned...

BACKGROUND: Due to the lack of prospective data there is an ongoing debate about the need for screening and prevention programs for congenital toxoplasmosis in Europe. Accordingly, individual countries have chosen different public health strategies. METHODS: A cord-blood screening program for congenital toxoplasmosis was established in 1982 in obstetric units of hospitals in North-Western Switzerland. Samples were tested for specific IgG and IgM, and after 1992 also for IgA antibodies...

PURPOSE: This study was performed to retrospectively assess the efficacy of percutaneous creation of an intervascular bypass with or without stent graft deployment (endovascular bypass) for salvage of abandoned vascular access sites in hemodialysis catheter-consigned patients. METHODS: Salvage of abandoned vascular access sites was attempted in 16 patients with hemodialysis catheters. These vascular access sites were salvaged using endovascular bypass techniques to redirect the access flow to a nonarterialized vein as a new outflow conduit or cannulation segment...

BACKGROUND: Even if the jejunoileal bypass has been definitely abandoned due to the high rate of hepatic complications, cases of liver injury after the new bariatric procedures are still reported. We aimed to review the available literature concerning liver damage associated with the older and newer types of bariatric surgeries. METHODS: An extensive literature search of MEDLINE was performed using different combinations of the following terms: "bariatric surgery OR biliopancreatic diversion OR jejunoileal bypass OR roux-en-y gastric bypass OR vertical banded gastroplasty OR laparoscopic adjustable gastric banding" AND "hepatic/liver damage OR hepatic/liver impairment OR hepatic/liver failure"...

Marine omega-3 fatty acids promote resolution of inflammation and have potential to reduce risk of obesity-related breast cancer. For prevention trials in obese women, inflammatory cytokines, aromatase, and measures of breast immune cell infiltration are logical, as are biomarkers of growth factor, adipokine, and estrogen signaling. Where best to look for marker change: in the circulation (easiest), in benign breast tissue (most relevant), or in visceral adipose (inflammation often most marked)? A null biomarker modulation trial may reflect limitations in design, source and dose of fatty acids, or biomarkers and should not lead to premature abandonment of marine omega-3 fatty acids for cancer prevention...

In a changing world with rapidly evolving new technologies, even in the "sheltered world" of teachers and lecturers at universities, we are challenged by new developments. As diversification is increasing in many aspects of our professional life, there is also a need to employ new ways of teaching, learning and assessments in veterinary curricula, taking into account the increasing numbers of students and limited teaching resources. The "classical" Austrian veterinary curriculum, with a series of consecutive lectures followed by practical courses in the different disciplines, separated from each other in the curricular time table and by annual examinations, has been a long-standing concept for teaching in the past...

Bronchial thermoplasty (BT) is a recently introduced bronchoscopic treatment for patients with asthma refractory to pharmacotherapy. Intraprocedural sedation management is important for successful performance of BT. However, the results of general anesthesia in patients undergoing BT have not been well described. The aim of this study was to evaluate the feasibility and safety of general anesthesia in patients undergoing BT. We retrospectively reviewed the records of 10 consecutive BT treatments performed under general anesthesia in 4 patients...

Soil contamination due to atmospheric deposition of metals originating from smelters is a global environmental problem. A common problem associated with this contamination is the discrimination between anthropic and natural contributions to soil metal concentrations: In this context, we investigated the characteristics of soil contamination in the surrounding area of a world class smelter. We attempted to combine several approaches in order to identify sources of metals in soils and to examine contamination characteristics, such as pollution level, range, and spatial distribution...

The lack of management in small-scale mining operations has the potential for negative repercussions, e.g., mine collapses, compared with well-regulated large-scale mines. Here, we used an in vitro model to investigate heavy metal soil pollution characteristics and their attendant health risks in an abandoned, small-scale lead (Pb) and zinc (Zn) mine located in southwestern China that had suffered from collapse. Our results showed the following: (1) Even the mine had been closed for many years, the soil was still heavily polluted by Pb, cadmium (Cd), and Zn, and there is a risk of secondary pollution...

INTRODUCTION: Among the various options for internal fixation of acetabular fractures, the enlarged iliofemoral approach is less often used, being more invasive, although providing greater exposure enabling control of all components in complex fractures. Even so, the impact of its invasiveness has not been confirmed, and long-term results are not known. We therefore performed a retrospective study, aiming 1) to assess long-term functional outcome, and 2) to assess associated morbidity...

There is consensus that only a preventive vaccine can contain the HIV/AIDS pandemic. After 30 years still there is no preventive HIV vaccine. This article examines fundamental challenges to the development of a preventive HIV vaccine. They include the initially erroneous but powerful perception of the natural history of HIV disease, as an acute rather than a chronic illness even in the absence of therapy, the lack of appreciation of the quasispecies biology of HIV and the abandonment of principles of immunology theory caused by the allure of technological prowess...

INTRODUCTION: Bariatric surgery is considered the most effective treatment for obesity. A recent worldwide survey demonstrated that Laparoscopic Sleeve Gastrectomy (LSG) is the most commonly performed bariatric procedure, while Laparoscopic Adjustable Gastric Banding (LAGB) has been almost abandoned. OBJECTIVES: The aim of this retrospective study was to compare 5-year results of LSG and LAGB at our Institution. MATERIALS AND METHODS: Prospective maintained database of our Institution was reviewed to find all patients who had undergone LSG between January 2009 and December 2011...

Proximal tibial metaphyseal fractures in children can lead to progressive and symptomatic tibial valgus. Corrective osteotomy has been abandoned, due to frequent complications, including recurrent valgus deformity. While spontaneous remodelling has been reported, this is not predictable. For children with persistent deformities, we have resorted to guided growth of the tibia. We present 19 patients who were successfully treated with guided growth, tethering the proximal medial physis. There were ten boys and nine girls, ranging in age from two to 13...

West Texas' Permian Basin, consisting of ancient marine rocks, is underlain by water-soluble rocks and multiple oil-rich formations. In the region that is densely populated with oil producing facilities, many localized geohazards, such as ground subsidence and micro-earthquakes, have gone unnoticed. Here we identify the localized geohazards in West Texas, using the satellite radar interferometry from newly launched radar satellites that provide radar images freely to public for the first time, and probe the causal mechanisms of ground deformation, encompassing oil/gas production activities and subsurface geological characteristics...

There is increasing interest in the restoration/regeneration of degraded tropical habitats yet the potential role of natural regenerators remains unclear. We test the hypothesis that the richness and functional diversity of terrestrial mammals differs between forest regrowth stages. We quantified the richness and functional diversity of eight terrestrial mammal seed-disperser species across a forest regrowth gradient in the eastern Brazilian Amazon. We installed camera-traps in 15 sites within small-holder properties with forest regrowth stage classified into three groups, with five sites each of: late second-regrowth forest, early second-regrowth forest and abandoned pasture...

INTRODUCTION: Respectful and dignified healthcare is a fundamental right for every woman. However, many women seeking childbirth services, especially those in low-income countries such as Pakistan, are mistreated by their birth attendants. The aim of this epidemiological study was to estimate the prevalence of mistreatment and types of mistreatment among women giving birth in facility- and home-based settings in Pakistan in order to address the lack of empirical evidence on this topic...

Electric field induced micro/nano patterns in thin polymer film, sometimes referred as electrohydrodynamic patterning, is a promising technique to fabricate micro/nano structures. Extensive attentions have been attracted due to its advantages in micro contact (easy demolding) and low cost. Although considerable work has been done on this technique, including both experimental and theoretical ones, there still appears a requirement for understanding the mechanism of electrohydrodynamic patterning. Thus we systematically studied the effect of different parameters on electrohydrodynamic patterning with a numerical phase field model...
