Assessment and correction of femoral malrotation following intramedullary nailing of the femur. (2010)

Rotational deformity is a more common problem than one might expect in the treatment of femoral shaft fractures. This review presents two cases of femoral malrotation following intramedullary nailing of the femur. The presentation, importance of early recognition, investigation with a CT scan, and the technique of correction is discussed in detail. The importance of intra-operative assessment to avoid this complication is highlighted and a review of the current literature on this problem and its treatment is presented.
Steady-State Kinetic Analysis of Phosphotransacetylase from Methanosarcina thermophila (2006)

Phosphotransacetylase (EC 2.3.1.8) catalyzes the reversible transfer of the acetyl group from acetyl phosphate to coenzyme A (CoA), forming acetyl-CoA and inorganic phosphate. A steady-state kinetic analysis of the phosphotransacetylase from Methanosarcina thermophila indicated that there is a ternary complex kinetic mechanism rather than a ping-pong kinetic mechanism. Additionally, inhibition patterns of products and a nonreactive substrate analog suggested that the substrates bind to the enzyme in a random order. Dynamic light scattering revealed that the enzyme is dimeric in solution.
Performance of fast forward link power control for CDMA systems (2002)

Fast power control is being considered on the forward link for the third generation CDMA systems. This paper simulates fast power control on the forward link for a 9600 bps data rate and discusses potential capacity gains. Performance of the fast power control scheme for 800 and 1600 Hz power control update rates are given to determine the potential capacity improvements as the update rate is increased. The paper also discusses some of the issues that need to be considered in designing fast power control for the forward link.
A Comparison of Clinical Outcomes of Dislocated Intraocular Lens Fixation between In Situ Refixation and Conventional Exchange Technique Combined with Vitrectomy (2016)

Purpose. To evaluate surgical efficacy of in situ refixation technique for dislocated posterior chamber intraocular lens (PCIOL). Methods. This was a single-center retrospective case series. 34 patients (34 eyes) who underwent sclera fixation for dislocated IOLs combined with vitrectomy were studied. Of 34 eyes, 17 eyes underwent IOL exchange and the other 17 eyes underwent in situ refixation. Results. Mean follow-up period was 6 months. Mean logMAR best corrected visual acuity (BCVA) was not significantly different between the groups 6 months after surgery (0.10 ± 0.03 in the IOL exchange group and 0.10 ± 0.05 in the refixation group; p = 0.065). Surgically induced astigmatism (SIA) was significantly lower in the refixation group (0.79 ± 0.41) than in the IOL exchange group (1.29 ± 0.46) (p = 0.004) at 3 months, which persisted to 6 months (1.13 ± 0.18 in the IOL exchange group and 0.74 ± 0.11 in the refixation group; p = 0.006). Postoperative complications occurred in 3 eyes in the IOL exchange group (17.6%) and 2 eyes in the refixation group (11.8%). However, all of the patients were well managed without additional surgery. Conclusion. The in situ refixation technique should be preferentially considered if surgery is indicated since it seemed to produce a sustained less SIA compared to IOL exchange.
Radiosynthesis of 6’-Deoxy-6’[18F]Fluorosucrose via Automated Synthesis and Its Utility to Study In Vivo Sucrose Transport in Maize (Zea mays) Leaves (2015)

Sugars produced from photosynthesis in leaves are transported through the phloem tissues within veins and delivered to non-photosynthetic organs, such as roots, stems, flowers, and seeds, to support their growth and/or storage of carbohydrates. However, because the phloem is located internally within the veins, it is difficult to access and to study the dynamics of sugar transport. Radioactive tracers have been extensively used to study vascular transport in plants and have provided great insights into transport dynamics. To better study sucrose partitioning in vivo, a novel radioactive analog of sucrose was synthesized through a completely chemical synthesis route by substituting fluorine-18 (half-life 110 min) at the 6' position to generate 6'-deoxy-6'[(18)F]fluorosucrose ((18)FS). This radiotracer was then used to compare sucrose transport between wild-type maize plants and mutant plants lacking the Sucrose transporter1 (Sut1) gene, which has been shown to function in sucrose phloem loading. Our results demonstrate that (18)FS is transported in vivo, with the wild-type plants showing a greater rate of transport down the leaf blade than the sut1 mutant plants. A similar transport pattern was also observed for universally labeled [U-(14)C]sucrose ([U-(14)C]suc). Our findings support the proposed sucrose phloem loading function of the Sut1 gene in maize, and additionally demonstrate that the (18)FS analog is a valuable, new tool that offers imaging advantages over [U-(14)C]suc for studying phloem transport in plants.
Liver lipid profiles of adults taking therapeutic doses of aspirin (1992)

The distributions of lipids of hepatic specimens obtained at autopsy from 7 adult patients who had been taking large amounts of aspirin for arthritis were compared to 7 control samples obtained from livers of autopsied adults without prior liver disease. The total neutral lipid levels of control livers were approximately one-third lower than those observed for livers of patients on aspirin. In addition, the phospholipid content of control specimens was significantly greater than that of livers from adult patients that had been on a high dose of aspirin for a long time. Examination of individual lipid classes showed that the concentrations of free fatty acids, triacylglycerols, and mono- and diacylglycerols were highest in livers of patients with aspirin exposure, and that all phospholipids were diminished. Phosphatidylcholines and phosphatidylethanolamines showed the greatest decrease. These results suggest that the livers of patients taking large amounts of aspirin may accumulate fatty acids and neutral lipids due to an impairment in the oxidation of fatty acids by hepatocytes. The data obtained also suggest that needle biopsy of the liver with measurement of distribution of hepatic lipids, perhaps together with histopathologic examination, may provide useful diagnostic information.
The uniqueness of glass for passive thermal management for optical fibers (2021)

Abstract Optical fiber‐based lasers and amplifiers are ubiquitous tools across many practical applications including communications, metrology, sensing, manufacturing, machining, and directed energy. Even for the most efficient cases where only a few percent of the optical power is converted into heat, this heat generation can have wide‐ranging detrimental effects on overall system performance. In homage to the 2022 International Year of Glass , this paper provides a new look into the enabling roles that glass can play in the fully passive thermal management of active fiber lasers and amplifiers. Partially didactic, complemented with new insights and novel approaches and results, specific topics include means by which glass compositions can reduce the amount of heat generated by an active dopant and how the glass’ response to heat generation, for example, thermo‐optic and thermal expansion coefficients, can be minimized or otherwise used to largely mitigate parasitic thermal effects.
Embedded image coding using zeroblocks of subband/wavelet coefficients and context modeling (2002)

In this paper, we present a new embedded wavelet image coding system using quadtree splitting and context modeling. It features low computational complexity and high compression efficiency, thanks to joint utilization of two powerful embedded coding techniques-set partitioning and context modeling. With effective exploitation of strong statistical dependencies among the quadtree nodes built up from subband coefficients, the proposed algorithm substantially improves the coding efficiency of the existing set-partition coders for both lossy and lossless image compression. For example, our experimental results show that the new algorithm respectively outperforms zerotree-based SPIHT and quadtree-based SPECK by 0.7 dB and 1.0 dB at 0.5 bpp on an average.
Non-Destructive Prediction of Pork Meat Degradation using a Stacked Autoencoder Classifier on Hyperspectral Images (2019)

This work presents initial results on a multitemporal hyperspectral image analysis method to evaluate the time degradation of pork meat. The proposed method is inexpensive and practically non-destructive. The hyperspectral data is analyzed and the relevant information is reduced to the information in only three wavelengths. The analysis is performed by a binary classifier composed by two stacked autoencoders and a softmax output layer. The use of autoencoders reduces tenfold the dimension of the input space. The proposed classifier has led to 97.2% of correct decisions, which indicates the great potential of the methodology to monitor the safety of meat.
Comparative study on bearing mechanism and design parameters of confined concrete arch joints in deep soft rock roadway (2019)

Abstract Square confined concrete arch is increasingly used in deep soft rock roadway support because of its advantages of high strength and construction convenience. However, the design of confined concrete arch in underground engineering still remains in experience-based method and lacks quantitative analysis. As a connecting component between arch sections, the connection joints have an important influence on the internal force distribution and failure mechanism of support arch. Therefore, a reasonable design of arch joints is the premise of rational support design. Taking Liangjia Coal Mine, a typical deep soft rock mine in China, as research background, this paper fully compared the most widely used joint types of confined concrete arch as analytical objects: flange joints and casing joints. The main failure modes of these two kinds of joints under bending moment are defined. Laboratory and numerical tests are carried out to study the mechanical characteristics of joints. Based on the M – θ curve, the influence law of different design parameters is analyzed, and the design principles of joints are proposed. The research results could provide a theoretical basis for the design and application of confined concrete arch in related projects.
Raman and Photoluminescence Study of Dielectric and Thermal Effects on Atomically Thin MoS2 (2012)

Atomically thin two-dimensional molybdenum disulfide (MoS2) sheets have attracted much attention due to their potential for future electronic applications. They not only present the best planar electrostatic control in a device, but also lend themselves readily for dielectric engineering. In this work, we experimentally investigated the dielectric effect on the Raman and photoluminescence (PL) spectra of monolayer MoS2 by comparing samples with and without HfO2 on top by atomic layer deposition (ALD). Based on considerations of the thermal, doping, strain and dielectric screening influences, it is found that the red shift in the Raman spectrum largely stems from modulation doping of MoS2 by the ALD HfO2, and the red shift in the PL spectrum is most likely due to strain imparted on MoS2 by HfO2. Our work also suggests that due to the intricate dependence of band structure of monolayer MoS2 on strain, one must be cautious to interpret its Raman and PL spectroscopy.
Interactions between lithium, inositol and mono-oleoylglycerol in the regulation of insulin secretion from isolated perifused rat islets (1989)

In response to stimulation by 20 mM-glucose, 15 mM-4-methyl-2-oxopentanoate or 10 mM-glyceraldehyde, isolated perifused rat islets respond with brisk biphasic insulin-secretory responses. The inclusion of 10 mM-LiCl significantly decreased second-phase insulin release in response to all agonists. Inositol, at a concentration (10 mM) which has no effect on secretion in the presence of 2.75 mM-glucose, restored significantly glucose-, 4-methyl-2-oxopentanoate- or glyceraldehyde-induced second-phase release from Li+-treated islets. The addition of the diacylglycerol kinase inhibitor mono-oleoylglycerol, at a concentration (25 microM) which has no stimulatory effect on insulin secretion in the presence of 2.75 mM-glucose, significantly amplified both the first- and second-phase insulin responses to 20 mM-glucose. This amplifying effect of mono-oleoylglycerol was readily reversible and dependent on Ca2+ influx into the beta-cell. Li+ decreased the amplified insulin response to 20 mM-glucose plus mono-oleoylglycerol. Inositol restored release under this condition. These findings suggest that Li+ inhibits release by sequestering inositol into biosynthetically ineffective inositol phosphates. By limiting phosphoinositide resynthesis, the continued hydrolysis of phosphoinositides is diminished. Our results with mono-oleoylglycerol suggest further that diacylglycerol content may play a critically important role in the regulation of both the first and second phases of insulin secretion.

The attenuation of seismic intensity in Italy (2005)

Seismic intensity is, by definition, an index for the classification of the severity of earthquake effects observed in a settlement. However the experience of many decades of its use within functional relations with other parametric quantities have shown that it represents a quite reliable estimator of ground motion amplitude and that it can be confidently related to instrumentally measured quantities by a logarithmic relation. Most intensity attenuation relations from the literature model empirically the difference between epicentral intensity I_0 (defined as the maximum observed intensity or something less that that) and the intensity at the site. This means assuming that I_0 is actually the average intensity observed at the epicenter and that it scales with site intensity with coefficient equal to 1. We analyzed the Italian macroseismic dataset that can be obtained by combining the two major Italian macroseismic databases following the choices made by the compilers of the parametric catalog of Italian earthquakes. It contains about 50,000 observations from ancient times to 1992. We considered an attenuation equation with log-linear dependence with hypocentral distance (depth fixed to 10 km) and an additional empirical term proportional to I_0 I_s=a + b D + c log{D} + d I_0 We found that: i) the intensity data observed at sites located at distance larger than the one at which the expected average intensity is below the limit of diffuse perceptibility (degree IV) are clearly incomplete and might bias the resulting attenuation relation, ii) intensity data with uncertain estimates (i.e. VI-VII) have frequencies lower of about 30-50% than regular ones and thus must be modeled separately, iii) the average intensity at the epicenter is on average from one to two degrees lower than I_0, iv) epicentral intensity contributes to the attenuation relation with a coefficient significantly different from 1.0 (about 0.7-08) thus indicating the it cannot be considered a reference ground-motion level but rather an estimator of the energy of the earthquake, v) the statistical distribution of intensity residuals closely resembles a normal one but with a significant skewness that can be appropriately modeled by a modified Azzalini distribution.

Susceptibility and lack of evidence for a viremic state of rabies in the night owl monkey, Aotus nancymaae (2012)

Our findings support the hypothesis that a viremic state for rabies does not exist in the New World Monkey, Aotus nancymaae, and it appears that this species may be refractory to infection. The species does provide a suitable model to assess post infection immune responses. Additional studies that address the limitations of sample size, length of observation, and lack of measurable infection should be conducted.
New mesogenic 1,3,4-oxadiazole derivatives (1991)

Abstract The synthesis of novel liquid-crystalline heteroaromatic compounds incorporating the five membered 1,3,4-oxadiazole ring is described. Due to the bent molecular structure of the oxadiazole ring their mesophase stability is low if the heterocyclic ring occupies a central position, but it is increased if this ring is shifted to a terminal position. Dielectric measurements indicate that the 2-n-alkylthio substitutes 1,3,4-oxadiazole derivatives change the sign of the dielectric anisotropy at the phase transition from the nematic to the smectic A phase. This effect is explained by the increase of the antiparallel correlation of the molecules on formation of the smectic layers.
Charge and spin order in the perovskite CaFe0.5Mn0.5O3: Charge disproportionation behavior of randomly arranged Fe4+ (2016)

$B$-site-disordered perovskite $\mathrm{CaF}{\mathrm{e}}_{0.5}\mathrm{M}{\mathrm{n}}_{0.5}{\mathrm{O}}_{3}$ with unusually high valence $\mathrm{F}{\mathrm{e}}^{4+}$ was synthesized using a high-pressure technique. $\mathrm{F}{\mathrm{e}}^{4+}$ randomly distributed at half of the $B$ sites shows charge disproportionation to $\mathrm{F}{\mathrm{e}}^{3+}$ and $\mathrm{F}{\mathrm{e}}^{5+}$. The spins of $\mathrm{F}{\mathrm{e}}^{3+},\phantom{\rule{0.16em}{0ex}}\mathrm{F}{\mathrm{e}}^{5+}$, and $\mathrm{M}{\mathrm{n}}^{4+}$ order below 90 K. Analysis of low-temperature neutron powder-diffraction data revealed a $G$-type antiferromagnetic structure---where all the nearest-neighboring spins of $\mathrm{F}{\mathrm{e}}^{3+},\phantom{\rule{0.16em}{0ex}}\mathrm{F}{\mathrm{e}}^{5+}$, and $\mathrm{M}{\mathrm{n}}^{4+}$ couple antiparallel---and the small ordered moment of $0.58\phantom{\rule{0.16em}{0ex}}{\ensuremath{\mu}}_{\mathrm{B}}$ reveals local charge ordering that gives rise to predominant $\mathrm{F}{\mathrm{e}}^{3+}$-O-$\mathrm{F}{\mathrm{e}}^{5+}$ antiferromagnetic arrangements. Despite the identical chemical compositions of $\mathrm{CaF}{\mathrm{e}}_{0.5}\mathrm{M}{\mathrm{n}}_{0.5}{\mathrm{O}}_{3}$ and $\mathrm{C}{\mathrm{a}}_{2}\mathrm{FeMn}{\mathrm{O}}_{6}$, the magnetic structure of the present $\mathrm{CaF}{\mathrm{e}}_{0.5}\mathrm{M}{\mathrm{n}}_{0.5}{\mathrm{O}}_{3}$ is very different from the noncollinear one of layered $B$-site-ordered $\mathrm{C}{\mathrm{a}}_{2}\mathrm{FeMn}{\mathrm{O}}_{6}$.
Dual-polarized chipless RFID tag with temperature sensing capability (2014)

In this paper dual-polarized chipless RFID tag with temperature sensing capability is proposed. The tag is constructed by incorporating a V-polarized and H-polarized slots containing either same or different code to increase the tag data capacity. The tag is having dual performance of tagging and temperature sensing simultaneously. The integration of temperature sensing is performed by utilizing the resonant frequency of a specific slot of the tag to represent the sensor change parameter. Different encoding techniques for different codes arrangement has been presented. The radiation characteristics of the chipless tag are investigated and analyzed using the finite element method and are compared with that obtained by the finite integration technique.
Surface preparation by using laser cleaning in thermal spray (2008)

Pulsed laser cleaning has emerged as a promising technology to challenge traditional surface preparation methods. This paper introduces the PROTAL® process, which combines an in situ pulsed laser cleaning with thermal spraying techniques. This laser surface preparation avoids some drawbacks of the traditional degreasing and sand-blasting stages prior to thermal spraying, which is especially meaningful for ductile and notch-sensitive materials. The laser induced phenomenon and the significant role of such laser irradiation in the coating deposition are presented.
The motor driving control of X-Y-Z table utilizing photoelectric device and optical pattern recognition (2003)

Position detectors which use the lateral photo effect are used for position detection and positioning on a X-Y-Z stage. Lasers (He-Ne, 632.8 nm) are used as light sources, and position sensing devices are used as light receptors. These devices are applied to absolute position detection on the X-Y-Z stage and to pattern recognition.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
155 The Efficacy of Durasphere as a New Agent for the Treatment of Hypermobile Glans (2016)

Despite proper sizing and placement of a penile implant, a subset of patients present postoperatively with glanular hypermobility. This is characterized by sensation of a soft glans penis, pain during intercourse associated with cylinder tip pressure, or the appearance of droopy glans with maximal inflation. Previous studies have discussed the use of PDE5 inhibitors and/or intraurethral alprostadil to treat the hypermobile glans. In this study we present our results of subcoronal Coloplast (Minneapolis, MN) Durasphere® injections as a surgical treatment for the hypermobile glans. Durasphere is a safe, sterile bulking agent composed of carbon-coated zirconium beads suspended in a water based beta-glucan gel. It has long been used as a bulking agent in the treatment of urinary incontinence caused by intrinsic sphincter deficiency (ISD). This is a retrospective review of 17 patients who underwent glanular bulking with Durasphere by a single surgeon from 2014-16. Patient data were compiled after extensive review of operative reports, inpatient notes, consult notes, and follow-up visits.
