Observation of the Volume Transition in Thermosensitive Core−Shell Latex Particles by Small-Angle X-ray Scattering (1998)

An investigation of the volume transition in colloidal core−shell particles composed of a temperature-independent polystyrene core and a shell of thermosensitive cross-linked polymer chains by small-angle X-ray scattering (SAXS) is presented. The PS cores of the particles have a diameter of 80 nm whereas the shell composed of cross-linked poly(N-isopropylacrylamide) has a thickness of 32 nm in the swollen state at 25 °C and of 18 nm after shrinking by a continuous volume transition. The SAXS intensities measured at high scattering angles could be described by a Lorentz-type function at both states. This indicates the presence of liquidlike local concentration fluctuations of the gel which are still present in the shrunken state. The correlation lengths ξ measured in both states are of the order of a few nanometers (25 °C, ξ = 3.2 nm; 50 °C, ξ = 2.1 nm). The present analysis therefore shows that the core−shell microgels behave in a distinctively different manner than ordinary thermosensitive gels: The cross-linked chains in the shell are bound to a solid boundary independent of temperature. The spatial constraint by this boundary decreases the maximum degree of swelling but also prevents a full collapse of the network above the volume transition.
Sequential changes in lower extremity function after total knee arthroplasty (2020)

TKA is useful for restoring lower limb function, as both ambulation and balance functions were significantly improved 3 months after surgery. However, no further improvement in ambulation or balance function was recognized beyond 3 months.
Carotene in bovine milk fat globules: Observations on origin and high content in tissue mitochondria (1980)

The location and origin of carotenoids in bovine milk fat globules was investigated using spectral absorption of lipid solutions at 461 nm to quantitate carotene. Release of membrane from globules as a result of churning to butter or by freezing and thawing of the globules yielded membrane preparations which were devoid of carotene. Globule cores from these procedures exhibited carotene concentrations comparable to those in total milk lipids. Fractionation of lactating bovine tissue and analysis of lipid extracts revealed that the intracellular fat droplets have carotene concentrations approximating those of secreted globules. However, intracellular membranes of the tissue, particularly the mitochondria, are much richer in carotenoids than formative or secreted fat globules. The evidence indicates that bovine milk fat globules acquire carotene during their formation in the cell, but that some minor fraction of the total carotene may be extracted from the enveloping secretory membrane. Mean carotene values (microgram/g of lipid) for fractions from three samples of lactating tissue were: whole tissue 47, mitochondria 461, microsomes 69, cytosol 67, fat droplets 8, milk 9. One tissue analysis indicated that Golgi membranes contain somewhat more carotene than do microsomes.
THE ONSET, CESSATION, AND RATE OF GROWTH OF LOBLOLLY PINES IN THE FACE EXPERIMENT (2004)

The Duke Forest FACE experiment was set up to investigate the impact of elevated CO2 levels on a larger eco system. One of the studies dealt with the impact of elevated CO2 levels on the onset and cessation of growth of loblolly pine trees (Pinus taeda L.). In this study the times of these events were determined for each year, 1996 - 2002. The rate of growth, the growth duration, and actual growth were determined from the models of onset and cessation of growth. Adjusted for initial basal area, the rate of growth, the actual growth, and the current basal area were slightly greater for elevated CO2 levels. There was no difference between the two CO2 levels for any of the time variables, onset, cessation, and growth period.
Study of low-rank high sulfur coal fine with biomass (2020)

Efficient combustion is important for the energetic recovery of coals. In the present study, thermogravimetric analysis (TGA) has been employed to obtain valuable information on the combustion characteristics of low-rank coal fine waste and acacia as biomass. Combustion profile indicates that acacia is helpful, for better ignition and burnout characteristics of coal due to the better reactivity and enhanced release of volatiles at lower temperature. The incorporation of acacia into the coal during combustion, decreases the ignition temperature and hence, yields a better combustion performance. Negligible amounts of ash and sulfur in the acacia sample, in comparison to the low-rank coal fines, are highly beneficial in order to reduce the emission of harmful sulfurous gases and particulate matters into the atmosphere. Statistical tools, such as Correlation Coefficient and Principal Component Analysis (PCA), have confirmed that blending low-rank coal fine waste with acacia biomass is highly beneficial for better ignition and efficient combustion.
Validation of an optical flow method for tag displacement estimation (1999)

We present a validation study of an optical-flow method for the rapid estimation of myocardial displacement in magnetic resonance tagged cardiac images. This registration and change visualization (RCV) software uses a hierarchical estimation technique to compute the flow field that describes the warping of an image of one cardiac phase into alignment with the next. This method overcomes the requirement of constant pixel intensity in standard optical-flow methods by preprocessing the input images to reduce any intensity bias which results from the reduction in stripe contrast throughout the cardiac cycle. To validate the method, SPAMM-tagged images were acquired of a silicon gel phantom with simulated rotational motion. The pixel displacement was estimated with the RCV method and the error in pixel tracking was <4% 1000 ms after application of the tags, and after 30 degrees of rotation. An additional study was performed using a SPAMM-tagged multiphase slice of a canine left ventricle. The true displacement was determined using a previously validated active contour model (snakes). The error between methods was 6.7% at end systole. The RCV method has the advantage of tracking all pixels in the image in a substantially shorter period than the snakes method.

Vibration of Water Sessile Drops in Various Oils (2017)

We study resonant frequencies of water sessile drops in various oils. The resonant frequency is experimentally obtained as the frequency shift of the scattered laser light, using an optical heterodyne technique. The resonant frequency is explained by the capillary wave propagating along the meridian curve of the drop with the fixed-end boundary condition at the three-phase contact line, although the sessile drop in air considerably deviates from the fixed-end boundary condition. We study this point further by observing the vibration directly with a fast video camera, and by analyzing the contour of the snapshot near the contact line. The results agree with the resonant frequency analysis results, where the number of half waves in the meridian curve of the water sessile drop is an integer when the drop is in oil, while in air, it deviates considerably from an integer.

Effect of dendritic cells (DC) transduced with chimeric antigen receptor (CAR) on CAR T-cell cytotoxicity. (2017)

144 Background: T cells interacting DC could be superior in T cell cytotoxicity. CD141+/Cleg9a+ intra-tumoral DC play a critical role in tumor cytotoxicity. Therefore, combining intra-tumoral DC in CAR T cell would safely increase localized CAR T cell cytotoxicity. We hypothesized that bioengineered DC compartment could be an excellent source for enhanced CAR T cell cytotoxicity. Methods: DC precursors and T cells of PBMC were transduced with a CAR (pCCL-anti-CD33-4-1BB-CD3z-T2A-GFP; CAR-DC or CAR T). For comparison, additional DC were transduced with 4-1BB cDNA (pCCL-4-1BB-T2A-GFP; 4-1BB-DC) or mock control (pCCL-eGFP). In addition to lentivirus transduction, differentiation of DC in vitro employed Flt3L/GM-CSF/IL-4. Transduced CAR T and CAR-DC were sorted by GFP expression at day 5. After further 10 days of culture, cells were harvested and analyzed for phenotype. An acute myeloid leukemia (AML) cell line (Kasumi-1) was treated with CAR T +/- CAR-DC, 4-1BB-DC, or mock control for functional assays. Results: Frequencies of cells expressing CD141+/Cleg9a+ were higher in 4-1BB-DC vs. control DC (33% vs. 1.5%). After mixing CAR T and CAR-DC (5X10 5 ) with Kasumi-1 (1X10 5 ) for 6 hours, CAR T/CAR-DC showed 100% Kasumi-1 cell cytotoxicity compared to 70% of CAR T by trypan blue. CAR T/CAR-DC also demonstrated higher Annexin V positive Kasumi-1 cells compared with CAR-T (91% vs. 52%). CAR T with or without CAR-DC were also assessed with multiplex immunoassays. CAR T cells mixed with CAR-DC induced higher level of IFN-gamma (10,316 vs. 6,186 pg/ml), IL-2 (68,840 vs. 64,708 pg/ml), and TNFalpha (1,361 vs. 905 pg/ml) (Kasumi-1 cells mixed with CAR-T cells of 10 E/T ratio) than CAR T cells. CAR-DC produced significantly higher IL-12 cytokine production (1,352 vs. 161 pg/ml) than CAR T cells in response to CD33 but independent to T cells, confirmed by comparing IL-12 production with CAR T/4-1BB-DC. Conclusions: These data show that in vitro differentiation of DC bearing 4-1BB increases CD141+/Cleg9a+ DC population and that interaction with CAR-DC to CAR T cells enhances anti-AML cytotoxicity. Our finding may implicate the development of CAR-DC therapy combined to CAR T cells to increase the efficiency of cancer immunotherapy.
A Tutorial on Particle Filtering and Smoothing: Fifteen years later (2008)

Optimal estimation problems for non-linear non-Gaussian state-space models do not typically admit analytic solutions. Since their introduction in 1993, particle filtering methods have become a very popular class of algorithms to solve these estimation problems numerically in an online manner, i.e. recursively as observations become available, and are now routinely used in fields as diverse as computer vision, econometrics, robotics and navigation. The objective of this tutorial is to provide a complete, up-to-date survey of this field as of 2008. Basic and advanced particle methods for filtering as well as smoothing are presented.
Density classification on infinite lattices and trees (2013)

Consider an infinite graph with nodes initially labeled by independent Bernoullirandom variables of parameter $p$. We address the density classification problem, that is, we want to design a (probabilistic or deterministic) cellular automaton or a finite-range interacting particle system that evolves on this graph and decides whether $p$ is smaller or larger than $1/2$. Precisely, the trajectories should converge to the uniform configuration with only $0$'s if $p<1/2$, and only $1$'s if $p>1/2$. We present solutions to the problem on the regular grids of dimension $d$, for any $d>1$, and on the regular infinite trees. For the bi-infinite line, we propose some candidates that we back up with numerical simulations.
Pseudomembranous Invasive Tracheobronchial Aspergillosis with Fulminant Hepatitis and Hemophagocytic Syndrome (2018)

Invasive tracheobronchial aspergillosis (ITBA), a rare form of invasive pulmonary Aspergillus infection (IPA), is predominantly confined to the tracheobronchial tree. We herein report a case of ITBA with severe necrotic pseudomembrane in a 57-year-old woman with fulminant hepatitis and hemophagocytic syndrome. Bronchoscopic findings revealed a widespread pseudomembranous formation of the trachea and bronchi. Aspergillus fumigatus was cultured from bronchial lavage fluid, and the histological findings of an endobronchial biopsy revealed necrosis and invasive hyphae. Although she responded to antifungal treatment, she ultimately died of a septic shock with Burkholderia cepacia 57 days after admission.
Wearable Haptic Systems for the Fingertip and the Hand: Taxonomy, Review, and Perspectives (2017)

In the last decade, we have witnessed a drastic change in the form factor of audio and vision technologies, from heavy and grounded machines to lightweight devices that naturally fit our bodies. However, only recently, haptic systems have started to be designed with wearability in mind. The wearability of haptic systems enables novel forms of communication, cooperation, and integration between humans and machines. Wearable haptic interfaces are capable of communicating with the human wearers during their interaction with the environment they share, in a natural and yet private way. This paper presents a taxonomy and review of wearable haptic systems for the fingertip and the hand, focusing on those systems directly addressing wearability challenges. The paper also discusses the main technological and design challenges for the development of wearable haptic interfaces, and it reports on the future perspectives of the field. Finally, the paper includes two tables summarizing the characteristics and features of the most representative wearable haptic systems for the fingertip and the hand.

Viscoelastic properties of collagen: synchrotron radiation investigations and structural model (2002)

Collagen type I is the most abundant structural protein in tendon, skin and bone, and largely determines the mechanical behaviour of these connective tissues. To obtain a better understanding of the relationship between structure and mechanical properties, tensile tests and synchrotron X-ray scattering have been carried out simultaneously, correlating the mechanical behaviour with changes in the microstructure. Because intermolecular cross-links are thought to have a great influence on the mechanical behaviour of collagen, we also carried out experiments using cross-link-deficient tail-tendon collagen from rats fed with beta-APN, in addition to normal controls. The load-elongation curve of tendon collagen has a characteristic shape with, initially, an increasing slope, corresponding to an increasing stiffness, followed by yielding and then fracture. Cross-link-deficient collagen produces a quite different curve with a marked plateau appearing in some cases, where the length of the tendon increases at constant stress. With the use of in situ X-ray diffraction, it was possible to measure simultaneously the elongation of the collagen fibrils inside the tendon and of the tendon as a whole. The overall strain of the tendon was always larger than the strain in the individual fibrils, which demonstrates that some deformation is taking place in the matrix between fibrils. Moreover, the ratio of fibril strain to tendon strain was dependent on the applied strain rate. When the speed of deformation was increased, this ratio increased in normal collagen but generally decreased in cross-link-deficient collagen, correlating to the appearance of a plateau in the force-elongation curve indicating creep. We proposed a simple structural model, which describes the tendon at a hierarchical level, where fibrils and interfibrillar matrix act as coupled viscoelastic systems. All qualitative features of the strain-rate dependence of both normal and cross-link-deficient collagen can be reproduced within this model. This complements earlier models that considered the next smallest level of hierarchy, describing the deformation of collagen fibrils in terms of changes in their molecular packing.
Design and Implementation of the Sense Egypt Platform for Real-Time Analysis of IoT Data Streams (2016)

Nowadays, we experience an abundance of Internet of Things middleware solutions that make the sensors and the actuators are able to connect to the Internet. These solutions, referred to as platforms to gain a widespread adoption, have to meet the expectations of different players in the IoT ecosystem, including devices [1]. Low cost devices are easily able to connect wirelessly to the Internet, from handhelds to coffee machines, also known as Internet of Things (IoT). This research describes the methodology and the development process of creating an IoT platform. This paper also presents the architecture and implementation for the IoT platform. The goal of this research is to develop an analytics engine which can gather sensor data from different devices and provide the ability to gain meaningful information from IoT data and act on it using machine learning algorithms. The proposed system is introducing the use of a messaging system to improve the overall system performance as well as provide easy scalability.
PHYSICAL PROPERTIES OF ELECTRON BEAM-CURED TRIPROPYLENEGLYCOLDIACRYLATE AND LIQUID CRYSTAL SYSTEMS (2004)

Some salient features of physical properties of Tripropyleneglycol diacrylate (TPGDA) and the low molecular weight nematic liquid crystal E7 are discussed. A variety of experimental techniques giving complementary information of monomer and Electron Beam (EB) cured systems are employed to illustrate the effect of curing. A detailed thermophysical analysis is made first to assess the conditions of miscibility, determine the order-disorder transition and the glass transition temperature. DSC spectra yield the energy change at the transitions from which important parameters are readily extracted such as solubility limits and amount of liquid crystal dissolved in the polymer. Polarized Optical Microscopy enables us to follow phase transitions and morphology changes in different regions of the phase diagram. Consistent data are obtained from mechanical measurements in particular with regards to the variation of the glass transition temperature with liquid crystal concentration and the related plasticizing effect.
Purification and Properties of Extracellular Lipases with Transesterification Activity and 1,3-Regioselectivity from Rhizomucor miehei and Rhizopus oryzae (2017)

<i>Rhizomucor miehei</i> NRRL 5282 and <i>Rhizopus oryzae</i> NRRL 1526 can produce lipases with high synthetic activities in wheat bran-based solid-state culture. In this study, the purification and biochemical characterization of the lipolytic activities of these lipases are presented. SDS-PAGE indicated a molecular mass of about 55 and 35 kDa for the purified <i>R. miehei</i> and <i>Rh. oryzae</i> enzymes, respectively. <i>p</i>-Nitrophenyl palmitate (<i>p</i>NPP) hydrolysis was maximal at 40°C and pH 7.0 for the <i>R. miehei</i> lipase, and at 30°C and pH 5.2 for the <i>Rh. oryzae</i> enzyme. The enzymes showed almost equal affinity to <i>p</i>NPP, but the <i>V</i><sub>max</sub> of the <i>Rh. oryzae</i> lipase was about 1.13 times higher than that determined for <i>R. miehei</i> using the same substrate. For both enzymes, a dramatic loss of activity was observed in the presence of 5 mM Hg<sup>2+</sup>, Zn<sup>2+</sup>, or Mn<sup>2+</sup>, 10 mM <i>N</i>-bromosuccinimide or sodium dodecyl sulfate, and 5-10% (v/v) of hexanol or butanol. At the same time, they proved to be extraordinarily stable in the presence of <i>n</i>-hexane, cyclohexane, <i>n</i>-heptane, and isooctane. Moreover, isopentanol up to 10% (v/v) and propionic acid in 1 mM concentrations increased the <i>p</i>NPP hydrolyzing activity of <i>R. miehei</i> lipase. Both enzymes had 1,3-regioselectivity, and efficiently hydrolyzed <i>p</i>-nitrophenyl (<i>p</i>NP) esters with C8-C16 acids, exhibiting maximum activity towards <i>p</i>NP-caprylate (<i>R. miehei</i>) and pNP-dodecanoate (<i>Rh. oryzae</i>). The purified lipases are promising candidates for various biotechnological applications.
