Computer- Based Particle Shape Analysis for Classification, Recognition, Utilization

Field: Computer Science (Physical Sciences)

In materials processing industries, the ingredients as well as some of the products usually exist in three different forms; namely, gaseous form, liquid form, and powder form. Materials in these forms interface with each other during physical transformation, chemical reaction, and mechanical handling. Image processing and recognition has been a subject of intensive study during the past 15 years. It offers a variety of applications, including particle morphology studies. The main function of the object isolation system is to single out the desired objects from the picture for identification and recognition. Object isolation may be accomplished by thresholding, contour finding, edge detection, picture segmentation, and texture analysis. The problem of pattern recognition and classification may be treated as one of discriminating the input data, not between individual patterns but between pattern classes, via the search for features or attributes among members of a class.
Digital subtraction angiography as a method of screening for coronary artery disease during peripheral vascular angiography.

Field: Medicine (Health Sciences)

Since myocardial infarction is the major cause of perioperative and postoperative death following peripheral vascular surgery, an accurate method of screening for coronary artery disease in this group of patients is needed. Digital subtraction angiography (DSA) with the use of intra-arterial aortic root injection of contrast material was evaluated as a method of screening for coronary artery disease in patients undergoing angiography for peripheral vascular disease. The feasibility of this method was demonstrated in animal experiments. Fifteen milliliters of Renografin-76 was power injected into the aortic root of seven anesthetized 20 kg mongrel dogs. Normal coronary artery anatomy was clearly demonstrated with DSA, and a series of iatrogenically created stenoses and occlusions were accurately identified. Excellent definition of patent grafts to the left anterior descending and circumflex coronary arteries was obtained in two dogs that had undergone previous coronary artery bypass grafting. A balloon occluder on one graft was used to demonstrate partial and near-total obstruction of the bypass graft. We are currently studying the use of aortic root injections using DSA to determine coronary artery disease in patients having standard angiography for peripheral vascular disease. Adequate visualization of coronary arteries and bypass grafts with only 20 ml of contrast has been obtained. The potential ability of this technique to identify and allow treatment of life-threatening coronary artery lesions in patients prior to or simultaneously with peripheral vascular surgery may result in reduced mortality.
Digital Shack-Hartmann wavefront sensing

Field: Physics and Astronomy (Physical Sciences)

Wavefront sensor is designed to measure both intensity distribution and phase distortion of optical fields in real time and high accuracy. It can be widely used not only in measuring, diagnostic, but also in adaptive opticaI systems to compensate for phase distortions. The most well known and widely used Shack-Hartmann wavefront sensor consists of a lenslet array and a CCD camera. The wavefrontsurface under test is divided into a number of beamlets by a two-dimensional sub-apertures of the lenslet array, and each sub-aperture provides a separate focus on the detector of a CCD camera .Then the image spot arraycaptured by CCD can be used to estimate the wavefront local slopes. The centroids of sub-images generated by each lenslet are tested and the sensor output is a set of {x,y}spot positions. Since the SHWS has some advantages for wavefront measuring of a laser beam with a large aperture, and the noise properties of this sensor are well determinedand it is simple to operate sucha sensor, SHWS became the most popularwavefront sensor for adaptive optics. Generally, the wavefrontestimation procedure may be categorized as e

Results and Problems of Serbian Real Sector Privatization

Field: Economics, Econometrics and Finance (Social Sciences)

The process of privatization of the real sector of Serbian economy has not been completed after 17 years of implementation. In spite of certain results, the privatization in Serbia has been accompanied \nwith numerous problems and opposings. It is hard to believe that privatization could be successfully finished in planed period. So, it is obvious that renewed institutional framework is necessary for concluding \nprivatization in short time period.
Electrochemically Exfoliated Layered Carbons as Sustainable Anode Materials for Lead Carbon Hybrid Ultracapacitor

Field: Materials Science (Physical Sciences)

Abstract Lead‐carbon hybrid ultracapacitors (Pb−C HUC) have become apparent as a way out of the sulfation issue of lead‐acid batteries, simultaneously enhancing the system‘s power density and cycle life. In this work, exfoliated graphene oxides (EGO) were synthesized by the electrochemical exfoliation method followed by chemical activation and carbonization at 600 °C (AEGO‐600). The composite electrode delivered 800 F g −1 capacitance at 1 A g −1 . The Pb−C HUC fabricated using AEGO‐600 anode and PbO 2 cathode can achieve capacitance of 325 F g −1 at 10 A g −1 and retain 71 % capacitance after 15000 charge‐discharge cycles in the voltage range of 2.3–0.8 V. The highly stable capacitance was due to the formation of layered carbons in AEGO‐600 that enhanced the favorable electrolyte ion assessment to maximum active sites. Owing to the facile, cost‐effective synthesis approach and better charge storage behavior, the activated‐exfoliated graphene oxides thus produced could be suitable candidates for future hybrid ultracapacitor systems.
On the Complexity of a Matching Problem with Asymmetric Weights

Field: Computer Science (Physical Sciences)

We present complexity results regarding a matching-type problem related to structural controllability of dynamical systems modelled on graphs. Controllability of a dynamical system is the ability to choose certain inputs in order to drive the system from any given state to any desired state; a graph is said to be structurally controllable if it represents the structure of a controllable system. We define the Orientation Control Matching problem (OCM) to be the problem of orienting an undirected graph in a manner that maximizes its structural controllability. A generalized version, the Asymmetric Orientation Control Matching problem (AOCM), allows for asymmetric weights on the possible directions of each edge. These problems are closely related to 2-matchings, disjoint path covers, and disjoint cycle covers. We prove using reductions that OCM is polynomially solvable, while AOCM is much harder; we show that it is NP-complete as well as APX-hard.
Abstract 286: Role of ATP-sensitive Potassium Channel Openers in Prevention of Atrial Fibrillation

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Introduction: The ATP-sensitive potassium (K ATP ) channel dysfunction causes susceptibility to adrenergic atrial fibrillation (AF). However, the therapeutic efficacy of K ATP activation in primary prevention of AF is not known. We hypothesized that K ATP channel opening drugs prevent AF with effective metabolic and mechanosensitive gating of K ATP channels and preserving electro-anatomical stability in atria by regulating oxidative and metabolic states. Methods: This hypothesis was tested in a novel mouse model of AF, cardiac specific LKB1 knockout (KO) mice. Male and female LKB1 KO mice were treated with K ATP channel openers, nicorandil (15 mg/kg/day) and diazoxide (10 mg/kg/day). Control group included untreated littermates of the study group. Incidence of AF, structural and electrophysiological property of atria and sex-based differences were analyzed at the 3 months of age in all groups. Results: The incidence of spontaneous AF was significant reduced in LKB1 KO male mice with nicorandil (0%, n=5) and diazoxide (33%, n=6) treatment compare to untreated mice (84.6%, n=13) (p<0.05). The treatment was also effective in female LKB1 KO mice as AF occurred in 37.5% of nicorandil (n=8) and 40% of diazoxide (n=5) (p<0.05) treated mice as oppose to 71% of untreated mice (n=24). The K ATP openers, particularly nicorandil, were more effective in male mice preventing AF. There was 100% risk reduction with nicorandil in male mice compare to 39% with diazoxide. Nicorandil demonstrated 52% risk reduction in female mice while it was 56% with diazoxide treatment. Prevention of AF was associated with preservation of atrial structural and electrical property including size, heart rate and conduction intervals. Biatrial enlargement was significantly prevented by K ATP openers compare to untreated mice. Incidence of AF was significantly higher in male mice than female with or without treatment. Conclusions: Activation of sarcolemmal and mitochondrial K ATP channels prevents AF by preserving electro-anatomical property of atria and decreasing susceptibility to AF. Metabolic regulation of K ATP is essential in AF. Thus, the K ATP openers are novel upstream therapy for primary prevention of AF in vulnerable population.
Bilateral Anterior Cerebral Artery Infarction: A Rare but Catastrophic Stroke Syndrome

Field: Medicine (Health Sciences)

I. Case Report A 63 year-old right-handed man was referred to the emergency unit of a hospital in Calabar, Nigeria, with symptoms of sudden weakness of the left lower limb of 6 days duration, right lower limb weakness of 5 days duration, and loss of consciousness during the last 3 days. His problems started with sudden severe numbness and weakness of the left lower limb on waking in the morning. There was no preceding headache, vomiting or seizures. A day later, the patient noticed similar symptoms on the right lower limb though symptoms remained worse on the left limb. There was no other relevant past medical history. The patient was diagnosed with hypertension seven years prior to the current presentation, and was treated with Ramipril and Amlodipine; however, he was not compliant with follow-up hospital visits. For the symptoms above, he was admitted into a peripheral centre on the same day of symptoms onset and received antihypertensive medication, dextrose and sedatives because of restlessness. His blood pressure ranged between 160-180/80-100mmHg. The patient lapsed into unconsciousness 3 days after admission and was thus transferred to our larger centre in the same town. On examination, he was unconscious, febrile (38.8 C), with no pallor, anicteric, and acyanosed. His Glasgow coma scale (GCS) was 3/15. The pupils were normal in size but showed a sluggish reaction to light, doll’s eye movement was intact and there was no obvious cranial nerve VII palsy. He had reduced tone on both upper limbs, increased tone on the left lower limb and reduced reflexes on both upper and lower limbs. There were no signs of meningeal irritation or frontal release signs. His heart rate was 88 beats per minute and regular with a blood pressure of 210/90mmHg. There was cardiomegaly with a 4th heart sound but without any murmurs. He had three (4X3cm) infected decubitus ulcers on the gluteal area. Investigations revealed normal serum glucose levels (8.3mmol/l), leucocytosis (15.2 X109/ul), with neutrophils accounting for 66%. Lipid profile was deranged showing total cholesterol of 7.70mmol/l and LDL cholesterol of 4.98mmol/l. There was hyperuricemia with uric acid level at 0.77mmol/l. INR was 1.16. A noncontrast CT scan of the brain revealed acute bilateral cerebral infarctions in the anterior cerebral artery territories. A diagnosis of coma due to bilateral ischemic anterior cerebral artery stroke complicated with infected decubitus ulcers was made. The patient was managed conservatively with intravenous mannitol and frusemide, normal saline, vitamin B complex, vitamin C, intravenous ceftriaxone (2g daily), supportive oxygen therapy, daily wound dressing and regular turning as well as application of compression stockings on the limbs. A nasogastric tube was inserted, through which he received oral dipyridamole, vasoprin, artovastatin, allopurinol and feeding. His condition however did not improve and the GCS remained 3/15 until his death on the fifth day of admission to our centre.
Cytosolic Hsp60 Is Involved in the NF-kB-Dependent Survival of Cancer Cells via IKK Regulation

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Cytoplasmic presence of Hsp60, which is principally a nuclear gene-encoded mitochondrial chaperonin, has frequently been stated, but its role in intracellular signaling is largely unknown. In this study, we demonstrate that the cytosolic Hsp60 promotes the TNF-a-mediated activation of the IKK/NF-kB survival pathway via direct interaction with IKKa/b in the cytoplasm. Selective loss or blockade of cytosolic Hsp60 by specific antisense oligonucleotide or neutralizing antibody diminished the IKK/NF-kB activation and the expression of NF-kB target genes, such as Bfl-1/A1 and MnSOD, which thus augmented intracellular ROS production and ASK1-dependent cell death, in response to TNF-a. Conversely, the ectopic expression of cytosol-targeted Hsp60 enhanced IKK/NF-kB activation. Mechanistically, the cytosolic Hsp60 enhanced IKK activation via upregulating the activation-dependent serine phosphorylation in a chaperone-independent manner. Furthermore, transgenic mouse study showed that the cytosolic Hsp60 suppressed hepatic cell death induced by diethylnitrosamine in vivo. The cytosolic Hsp60 is likely to be a regulatory component of IKK complex and it implicates the

Accelerated Aging Effect on the Stability of the 3D-Printed Biodegradable Implant for Bone Defect Repairs

Field: Materials Science (Physical Sciences)

This article presents an evaluation of the accelerated aging impact on the structural properties of biodegradable PLA/HAp implants produced using 3D printing technology for use in traumatic bone defect repairs in individual patients. The designed biodegradable implants were sterilized with a radiation dose of 25 ± 0.99% kGy, then exposed to an accelerated aging process. Selected physicomechanical and chemical properties of biodegradable implants were evaluated with FT-IR spectra analyses and DSC. The accelerated aging process, carried out according to the ASTM F 1980:2002 “Standard Guide for Accelerated Aging of Sterile Barrier Systems and Medical Devices”, simulates three years of implant usage. It confirmed the stability of structural, physical and mechanical properties and proved the effectiveness and safety of the implants’ application. The present study was conducted to determine the shelf-life of newly developed biodegradable implants proposed for the treatment of children and adolescents where bone growth still occurs by using accelerated aging methodologies, allowing the assessment of changes in performance that do not result in a negative impact on the safety of the medical device.

Influence of the Sputtering Temperature on Reflectivity and Electrical Properties of ITO/AgIn/ITO Composite Films for High-Reflectivity Anodes

Field: Materials Science (Physical Sciences)

In this paper, indium tin oxide/silver indium/indium tin oxide (ITO/AgIn/ITO) composite films were deposited on glass substrates by magnetron sputtering. The effects of the sputtering temperature on the optical and electrical properties of the composite films were systematically investigated. The ITO/AgIn/ITO composite films deposited at sputtering temperatures of 25 °C and 100 °C demonstrated a high reflectivity of 95.3% at 550 nm and a resistivity of about 6.8–7.3 μΩ·cm. As the sputtering temperature increased, the reflectivity decreased and the resistivity increased slightly. The close connection between microstructure and surface morphology and the optical and electrical properties of the composite films was further illustrated by scanning electron microscopy imaging and atomic force microscopy imaging. It is shown that the ITO/AgIn/ITO thin films have a promising application for high-reflectivity anodes.

Retrospective study of more than 5 million emergency hospital admissions: epidemiology and outcomes for people with dementia

Field: Medicine (Health Sciences)

Abstract

BackgroundPeople with dementia (PwD) as emergency acute hospital admissions may be at higher risk of inappropriate care and poorer outcomes including longer hospitalisations and higher risk of emergency re-admission or death. Since 2009, numerous national and local initiatives in England have sought to improve hospital care for PwD. We compared outcomes of emergency admissions for patients aged 65+ with and without dementia across three points in time.MethodsWe analysed emergency admissions (EAs) from the Hospital Episodes Statistics datasets for England 2010/11, 2012/13 and 2016/17. Dementia upon admission was based on a diagnosis in the patient’s hospital records within the last five years. Outcomes were length of hospital stays (LoS), long stays (>=15 days), emergency re-admissions (ERAs) and deaths within 30 days of discharge. Covariates included patient demographics, pre-existing health and reasons for admission. Hospital indices of dementia care relating to staff training, hospital governance and patient-focus were derived from National Audit of Dementia survey returns. Hierarchical multivariate regression analysis was used - separately for males and females – to evaluate patient group differences on each outcome adjusted for covariates and to examine associations with the dementia care indices.ResultsWe included 178 acute hospitals with a total of 2,569,007 EAs for male patients and 3,011,099 for female patients, of which 356,992 (13.9%) were male PwD and 561,349 (18.6%) female PwD. Covariate-adjusted differences in LoS changed little over time and in 2016/17 were 17% (95%CI 15%-18%) and 12% (10%-14%) longer for male and female PwD respectively. Adjusted excess risk of an ERA for PwD reduced over time to 17% (15%-18%) for males and 17% (16%-19%) for females. Adjusted mortality for PwD was around 30% higher throughout. No associations were found between outcomes and hospital indices of dementia care.ConclusionsOver the six-year period, covariate-adjusted hospital LoS, ERA and mortality rates for PwD showed little beneficial change relative to similar patients without dementia, despite many national and local efforts to improve hospital care for this patient group. Group differences after adjustment were mostly small and may reflect factors beyond hospital control. Greater emphasis is needed on avoiding unnecessary hospitalisations for PwD.
The Relative Effect of Hypoxia and Gravity on Pulmonary Blood Flow

Field: Medicine (Health Sciences)

The influence on the partition ofpulmonary blood flow and ventilation and on arterial blood gas tensions by inhalation of different oxygen concentrations with the superior and inferior lung in the right decubitus position was mea- sured during bronchospirometry in seven experi- ments on 5 healthy volunteers. The partition of the pulmonary blood flow was measured from the quantity of intravenously injected 85Kr exhaled by each lung. In comparison to control values obtained during air breathing 10% oxygen (hypoxia) in the inferior and pure oxygen in the superior lung caused a highly significant redistribution of blood flow towards the superior lung. Also, hypoxia in the inferior lung with air in the superior caused a redistribution towards the superior lung too large to be due to chance and so did oxygen breathing in the superior lung. It was concluded that vasoconstriction from hypoxia could overcome the influence of gravitation on blood flow distribution and that gravitational factors alone could not explain the changes in distribution caused by oxygen breathing by the superior lung. Possible further mechanisms are discussed
