Controlled Lateral Positioning of Microparticles Inside Droplets Using Acoustophoresis (2015)

In this paper, we utilize bulk acoustic waves to control the position of microparticles inside droplets in two-phase microfluidic systems and demonstrate a method to enrich the microparticles. In droplet microfluidics, different unit operations are combined and integrated on-chip to miniaturize complex biochemical assays. We present a droplet unit operation capable of controlling the position of microparticles during a trident shaped droplet split. An acoustic standing wave field is generated in the microchannel, and the acoustic forces direct the encapsulated microparticles to the center of the droplets. The method is generic, requires no labeling of the microparticles, and is operated in a noncontact fashion. It was possible to achieve 2+-fold enrichment of polystyrene beads (5 μm in diameter) in the center daughter droplet with an average recovery of 89% of the beads. Red blood cells were also successfully manipulated inside droplets. These results show the possibility to use acoustophoresis in two-phase systems to enrich microparticles and open up the possibility for new droplet-based assays that are not performed today.
Geospatial Web Data Tessellation and Visualization (2011)

The Internet has penetrated to every aspect of our daily life. Users are feeding their georeferenced knowledge, preference, consumer patterns and behaviors, likes and dislikes, and living patterns to the Web. Proper understanding of these user-provided georeferenced Web data is of great importance. This article combines Web 2.0 and Geospatial Web to retrieve and map user-driven data, and mixes clustering and segmentation to identify informative cluster weighted areas of influence. Case studies are provided to illustrate the working principle of proposed framework, to show how the framework can be applied to many different scenarios, and to demonstrate the usefulness and applicability of the proposed framework.
Perovskite Microdisk Microlasers Self‐Assembled from Solution (2015)

Single-crystalline square microdisks of CH3NH3PbBr3 are prepared by using a one-step solution self-assembly method. Single-mode lasing at 557 nm is achieved based on a built-in whispering gallery mode microresonator at room temperature. By partial replacement of Br with Cl, lasing wavelengths are continuously tuned from 525 to 557 nm.
Developmental implications of intrauterine growth retardation (1992)

The population of infants with intrauterine growth retardation (IUGR) is a heterogeneous one; the unifying characteristic of these infants is that they are smaller than expected for their maturity at the time of birth. Their developmental outcome, which describes a spectrum of developmental disabilities, is related to the etiology of the IUGR, timing of the insult, and associated perinatal complications. IUGR is merely a marker that the central nervous system, along with other organ systems, may be affected.
Optical fiber magnetic field sensors with ceramic magnetostrictive jackets (1996)

Optical fibers coated by magnetostrictive ceramic films were tested with a Mach-Zehnder interferometer in an open-loop mode. The sensors exhibited excellent linearity and good sensitivity. The response of ceramic-jacketed fibers was not affected by small dc fluctuations that are due to the linear behavior of tested ceramic coatings in low magnetic fields. Tested ceramic materials included magnetite, γ-Fe(2) O(3), nickel ferrite, and cobalt-doped nickel ferrite (NCF2) jackets. The latter showed the best performance. A minimum detectable field of 3.2 × 10(-3) A/m for optical fiber jacketed with 2-μm-thick and 1-m-long NCF2 material has been achieved. The capability of detecting magnetic fields as low as 2.6 × 10(-7) A/m with a 10-μm-thick cobalt-doped nickel ferrite jacket is proposed.
Modified Tamm-Dancoff approximation calculations using Lipkin-Nogami approach (1982)

The number conservation as introduced by Lipkin and Nogami has been incorporated in the modified Tamm-Dancoff approximation method. The necessary relevant formulas arising due to this modification are derived and applied to the even Ni isotopes employing the Kuo-Brown effective interaction. A general improvement in agreement with experiments is obtained.NUCLEAR STRUCTURE MTDA method using Lipkin-Nogami approach, applied to Ni isotopes. Kuo-Brown interaction.
Efficacy of topical permethrin as repellent against Aedes aegypti's bites. (2008)

Mosquitoes are the most important vectors of infectious diseases and their bites are related to several adverse skin reactions. Permethrin impregnated clothes are an efficient strategy against arthropods' bites; however, its topical efficacy as a repellent has not been well established. We studied the response to permethrin lotion 5 percent and N,N-Diethyl-meta-toluamide (DEET) spray 50 percent applied to the unprotected forearms of 10 volunteers. Each arm was exposed to 20 female mosquitoes of Aedes aegypti. We performed 71 bilateral comparative measurements evaluating the timing for the first bites. The average times for the arm without the product, with permethrin 5 percent, and with DEET 50 percent were: 7.9 seconds, 336.2 seconds and 7512.1 seconds. The results showed a significant difference between repellency times between either product and unprotected controls. In addition, there was a significant difference in time to first bite between permethrin and DEET treated arms (p<0.01). Permethrin affords some repellent activity against Aedes aegypti bites in this experimental setting. However, permethrin's profile of repellency was significantly inferior to that of DEET.
Congenital rubella affecting an infant whose mother had rubella antibodies before conception. (1981)

A woman who had had high titres of rubella antibodies some months before she became pregnant gave birth to an infant in whom congenital rubella was confirmed at 4 months. Rubella haemagglutination inhibition tests, complement fixation tests, and immunofluorescence tests with anti-human IgG were carried out on sera from the mother. Rubella antibody titres in sera obtained in March 1971, seven and a half months before conception, were equivalent to 400 units, which is usually taken as indicating good immunity. Rubella virus was isolated from the baby's nose and throat in July 1973 but was not isolated from a cervical swab taken from the mother in December 1973; tests of her immunological competence did not show any definite abnormality. The presence of high levels of rubella haemagglutination inhibition antibodies does not invariably confer immunity or exclude the possibility of congenital rubella in a subsequent pregnancy.

Hierarchical Back Projection Network for Image Super-Resolution (2019)

Deep learning based single image super-resolution methods use a large number of training datasets and have recently achieved great quality progress both quantitatively and qualitatively. Most deep networks focus on nonlinear mapping from low-resolution inputs to high-resolution outputs via residual learning without exploring the feature abstraction and analysis. We propose a Hierarchical Back Projection Network (HBPN), that cascades multiple HourGlass (HG) modules to bottom-up and top-down process features across all scales to capture various spatial correlations and then consolidates the best representation for reconstruction. We adopt the back projection blocks in our proposed network to provide the error correlated up and down-sampling process to replace simple deconvolution and pooling process for better estimation. A new Softmax based Weighted Reconstruction (WR) process is used to combine the outputs of HG modules to further improve super-resolution. Experimental results on various datasets (including the validation dataset, NTIRE2019, of the Real Image Super-resolution Challenge) show that our proposed approach can achieve and improve the performance of the state-of-the-art methods for different scaling factors.
Influence of the filler CaCO<sub>3</sub> on the cure kinetic of the epoxy network diglycidyl ether of bisphenol a (BADGE <i>n</i> = 0) with isophorone diamine (2009)

Abstract The influence of the presence of CaCO 3 on the cure reaction of the epoxy network diglycidyl ether of bisphenol A with isophorone diamine has been studied. The total enthalpy of reaction, the glass transition temperature and the partial enthalpies at different isothermal temperatures have been determined using differential scanning calorimetry (DSC) in dynamic and isothermal mode. A kinetic model accounting the influence of the diffusion of the reactive groups at high conversions was used. All the kinetic parameters have been compared with those of the system without filler (CaCO 3 ). © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Scatter reduction in mammography with air gap (1996)

Scatter reduction by air gaps in mammography was investigated. We have experimentally demonstrated that, independently of the imaging geometry, scatter in air-gap mammography can be well described by a virtual source of scatter (VSS) model. This model postulates that scatter radiation originates from a virtual point source of scatter placed on the central axis between the x-ray source and the exit surface of a patient at distance delta and utilizes only two parameters: delta and (S/P)0. The (S/P)0 parameter represents scatter-to-primary ratio without an air gap and delta is the distance from the exit surface of a patient to the virtual source of scatter. We have experimentally determined the analytical form of the two independent parameters of the VSS model; delta exhibits a linear increase proportional to the radiation field size, does not depend on patient thickness, and is in the 10-30 cm range, while (S/P)0 increases with the field size as a power function and is in the 0.4-1.3 range. In the framework of the VSS model the selectivity, the contrast improvement factor, and the signal-to-noise improvement factor were employed to evaluate performance of air-gap mammography systems. We have demonstrated that selectivity of an air gap rapidly deteriorates at some well-defined critical value of scatter fraction that has profound consequences on air-gap performance. Assuming fixed patient exposure, the results shows that, if a contrast limited detection system (such as film/screen mammography) is used, an air gap system can outperform a grid system only if a very large source-to-patient (SPD) distance is utilized, which might be possible with new laser-based x-ray sources. For the noise limited detection systems (such as digital mammography) even a small SPD (70 cm) and a small air-gap (20 cm) system will outperform a grid system.
Recent Advances in the Measurement Error Literature (2016)

This article reviews recent significant progress made in developing estimation and inference methods for nonlinear models in the presence of mismeasured data that may or may not conform to the classical assumption of independent zero-mean errors. The aim is to cover a broad range of methods having differing levels of complexity and strength of the required assumptions. Simple approaches that form the elementary building blocks of more advanced approaches are discussed first. Then, special attention is devoted to methods that rely on readily available auxiliary variables (e.g., repeated measurements, indicators, or instrumental variables). Results relaxing most of the commonly invoked simplifying assumptions are presented (linear measurement structure, independent errors, zero-mean errors, availability of auxiliary information). This article also provides an overview of important connections with related fields, such as latent variable models, nonlinear panel data, factor models, and set identification, and applications of the methods to other fields traditionally unrelated to measurement error models.
Optimization of Near Field Coupling for Efficient Power Transfer Utilizing Multiple Coupling Structures (2011)

A rise in the need for dynamic energy allocation has been associated with the saturation of available portable wireless electronic devices. Currently, the methods for transmitting this energy efficiently have been limited to a number of options, including near field resonant magnetic coupling. Previous research with mid-range (dâ 4r) wireless power transfer has resulted in coupling efficiencies of close to 40%. In order to increase efficiency in transfer a more directive transmission system was developed using a phased array. Coupling networks were used to shift the resonance of the coupling device, leading to a tightly coupled network by array phasing. Coupling networks for the phased array were optimized using a hybrid combination of a full wave Method of Moments simulation with circuit simulation. Results were validated in a full wave simulator, and field results were shown during resonance. S-parameter results show simulated transfer efficiencies of 70% (-1.5dB) for a phased array structure and 62.3% (-2.4dB) for a single feed structure. Single feed prototyping S-parameter results show coupling efficiencies of 25% (-5.9dB). All coupling measurements are at a distance 4r with reference to the largest transmitting coupler.

Spongiform Leukoencephalopathy Induced in Mice by Oral Benzidine Administration (1981)

Small foci of spongy change, often bilaterally symmetric, were observed in the brains of mice exposed to benzidine dihydrochloride. These vacuoles were most frequent in the superior thalamic radiation of the internal capsule. They possibly represent swollen glial cells and intramyelinic vacuoles. No consistent relationship was observed between the presence of vacuoles in the brain and hepatic lesions in these mice, and this change may be attributable to benzidine treatment unrelated to toxic effects of the liver.

Greener routes for recycling of polyethylene terephthalate (2015)

The article reviews the different routes for recycling of polyethylene terephthalate. Chemical recycling processes are divided into six groups: methanolysis, glycolysis, hydrolysis, ammonolysis, aminolysis, and other methods. In a large collection of researches for the chemical recycling of PET, the primary objective is to increase the monomer yield while reducing the reaction time and/or carrying out the reaction under mild conditions. This article also presents the impact of the new recyclable catalysts such as ionic liquids on the future developments in the chemical recycling of PET.

Benzoylation of p-Xylene at the Solid-Liquid Interface on Iron Incorporated Silica (2010)

A series of iron incorporated silica catalysts were prepared using rice husk ash as a source of silica. The specific surface areas of the catalysts were found to be in the range of 200-400 m 2 g -1 . The activities of the catalysts were tested for liquid phase Friedel-Crafts acylation reaction of p-xylene with benzoyl chloride. The catalyst RHA-10Fe exhibited the highest activity for benzoylation of p-xylene. The conversion of benzoyl chloride (BzCl) and the selectivity towards 2,5-dimethylbenzophenone (2,5-DMBP) were found to be 98.4 and 88.9 (%) respectively at 413 K.
Synthesis of Some Members of the Hydroxylated Phenanthridone Subclass of the <i>Amaryllidaceae</i> Alkaloid Family (2007)

The total synthesis of several members of the hydroxylated phenanthridone subclass of the Amaryllidaceae alkaloid family has been carried out. (+/-)-Lycoricidine and (+/-)-7-deoxypancratistatin were assembled through a one-pot Stille/intramolecular Diels-Alder cycloaddition cascade to construct the core skeleton. The initially formed [4+2]-cycloadduct undergoes nitrogen-assisted ring opening followed by a deprotonation/reprotonation of the resulting zwitterion to give a rearranged hexahydroindolinone on further heating at 160 degrees C. The stereochemical outcome of the IMDAF cycloaddition has the side arm of the tethered vinyl group oriented exo with respect to the oxygen bridge. The resulting cycloadduct was used for the stereocontrolled installation of the remaining functionality present in the C-ring of the target molecules. Key features of the synthetic strategy include (1) a lithium hydroxide induced tandem hydrolysis/decarboxylation/elimination sequence to introduce the required pi-bond in the C-ring of (+/-)-lycoricidine, and (2) conversion of the initially formed Diels-Alder adduct into an aldehyde intermediate which then undergoes a stereospecific decarbonylation reaction mediated by Wilkinson's catalyst to set the trans-B-C ring junction of (+/-)-7-deoxypancratistatin.
Food Insecurity and Hypoglycemia Among Safety Net Patients With Diabetes (2011)

In 2008, 1 in every 7 US households was food insecure, or at risk of going hungry because of an inability to afford food.(1) Food insecurity generally occurs cyclically and episodically, with periods of food adequacy followed by food scarcity; the average food insecure household experiences seven episodes of food scarcity annually.(2) We hypothesized that the cyclic nature of food insecurity, and its associated fluctuations in dietary intake, would predispose patients with diabetes to wide variations in blood glucose levels, including clinically significant hypoglycemia.

Energy Utilisation and Consideration in Industry (1979)

It is an unfortunate fact that much of Australia's energy consumption is both inefficient and wasteful. The Institution of Engineers Australia Task Force suggests that a target saving of between 15% and 25% per unit of output is readily achievable. The paper sets out a number of ways in which such targets are achieved in a range of well run and energy efficient industries, and suggests how designers and operators alike, should approach the problem where there is waste. Bogey energy consumptions per unit of output (MJ/t) for a wide range of industries are derived as the basis against which energy performance can be measured and targets for improved performance set. If energy waste is costed notionally (and very modestly) at $1 per/GJ a saving of 15% in mining and industrial energy utilization in Australia would have an annual value is 1979 approaching $200 million. To professional engineers in the field of energy conservation this represents a challenge that cannot be ignored.
제조업 전력 사용 효율성 제고를 통한 온실가스(CO2) 감축 잠재량 추정에 관한 연구 (2010)

본 연구에서는 생산 기술적 측면에서 개별 사업체의 투입요소 효율성을 제고함에 따라 절약할 수 있는 전력 사용량 및 이에 따른 온실가스 감축 잠재량을 추정하였다. 이를 위하여 자료포락분석기법(DEA)를 이용하여 제조업체의 투입요소 기술적 효율성을 추정하고 이를 토대로 온실가스 저감량을 추정하였다. 2008년도 제조업체 평균 기술적 효율성은 규모에 대한 보수(Returns to Scale) 가정에 따라 0.467-0.643으로 추정되었다. 이를 토대로 제조업의 전력사용 효율성을 개선함에 따른 온실가스 절감가능량은 전력 사용에 따라 발생하는 총 온실가스 발생량의 17.1-25.5%에 해당하는 양으로 추정되었다. 우리 정부가 2020년까지 온실가스를 BAU 대비 30% 가량 감축하기로 발표하였는데 본 연구에서처럼 제조업체 투입요소의 기술적 효율성을 제고함으로써 이러한 정부 정책 실현을 가시화할 수 있을 것이다.
PROSTATIC ABSCESS (1929)

Abscess of the prostate may occur in two ways. The first type is due to the direct extension of a gonorrheal infection of the posterior urethra, while the second type occurs as a metastatic involvement of the gland from some distal or general infection. Tuberculosis of the prostate is not considered in this report. The diagnosis of this lesion is usually not difficult; but some patients may lack any positive symptoms directing attention to the prostate, and in others definite softening or fluctuation of the gland does not occur. Harlow Brooks<sup>1</sup>tells of a young physician under observation for several weeks who was studied by many physicians before any signs or symptoms of prostatic infection directed attention to the prostate. A probable diagnosis of paratyphoid was made. Only slight rectal irritation late in the disease called attention to the prostate. Rupture took place into the urethra, followed by complete
