ROMeasure: A Practical Solution For Accurate Range Of Motion Analysis Using A Smartwatch (2022)

Muskuloskeletal disorders produce a profound effect on osteokinematics of the human body. Range of Motion (ROM) is a very effective marker reflecting the health of affected joints and is estimated by orthopaedicians usually by performing manual measurements using a goniometer which is both inconvenient and lack the ability to peform an accurate, real time analysis of the full rotational movement. Motion sensors embedded in wearables have been researched successfully for ROM estimation, but not without some drawbacks which hinder their practical use in a medical scenario, which include need of multiple wearable sensors, low accuracy while estimating ROM in a horizontal plane, and questionable accuracy at extremely slow rotational speeds. This work proposes &#x2018;ROMeasure&#x2019;, a wearable-based ROM estimation solution which aims to address the above shortcomings. We discuss a novel approach using a single wrist-wearable leveraging the relative invariance in axis of rotation during ROM measurement using gyroscope sensor present onboard the wearable. We demonstrate our solution&#x2019;s accuracy by performing different ROM rotations for elbow and shoulder joints using a smartwatch, with an angle-graduated board and goniometer as sources of ground truth measurement. Output parameters and a video feed of subject performing the movements is displayed on a dashboard in real-time which can be of great assistance to a specialist for analysing the motion, and also makes ROMeasure a great fit for a tele-health scenario.
Tafazzin knockdown in murine mesenchymal stem cells enhances the tafazzin knockdown mediated elevation in interleukin-10 secretion from murine B lymphocytes (2023)

Abstract Barth Syndrome is a rare X-linked genetic disorder caused by mutations in the TAFAZZIN gene. We recently demonstrated that tafazzin (Taz) protein deficiency in murine mesenchymal stems (MSCs) reduces immune function of activated wild type (WT) B lymphocytes. Interleukin-10 (IL-10) is a key anti-inflammatory cytokine capable of exerting immunosuppressive effects on myeloid cells. Here we examined if Taz deficiency in murine MSCs altered proliferation and IL-10 production in Taz deficient lipopolysaccharide (LPS)-activated murine B lymphocytes. Bone marrow MSCs and splenic B lymphocytes were isolated from WT or Taz knockdown (TazKD) mice. WT or Taz deficient MSCs were co-cultured with either LPS-activated WT or LPS-activated Taz deficient B lymphocytes for 24 h and B cell proliferation and IL-10 production determined. Taz deficient MSCs exhibited increased phosphatidylinositol-3-kinase (PI3K) mRNA expression compared to WT MSCs indicative of enhanced immunosuppression. Co-culture of Taz deficient MSCs with Taz deficient LPS-activated B cells resulted in a greater reduction in proliferation of B cells compared to Taz deficient MSCs co-cultured with LPS-activated WT B cells. In addition, co-culture of Taz deficient MSCs with Taz deficient LPS-activated B cells resulted in an enhanced production of IL-10 compared to Taz deficient MSCs co-cultured with LPS-activated WT B cells. Thus, Taz deficiency in murine MSCs potentiates the Taz knockdown-mediated elevation in IL-10 secretion from LPS-activated Taz knockdown B lymphocytes. These data suggest that Taz deficient MSCs may modulate the activity of other Taz deficient immune cells potentially promoting an enhanced immunosuppressive state.

Transform-domain super-resolution for multiview images using depth information (2011)

Mixed resolution formats have been employed in video encoding complexity reduction as well as data compression of stereoscopic video. High resolution frames within such formats may also be used as a means of enhancing lower resolution images. In this paper we present a super-resolution method for use in a mixed resolution, multiview video plus depth setup. High resolution views are initially projected onto the view point of low resolution images with the aid of available depth maps. The method introduces the use of transform-domain techniques for up-sampling the low resolution images and for appending high frequency content from projected views. The DCT is used for the necessary frequency decompositions. Results show gains over previous work for several test sequences and affirm the aptitude of transform-domain approaches for super-resolution within mixed resolution formats.

Manipulating the Self-Assembling Process to Obtain Control over the Morphologies of Copper Oxide in Hydrothermal Synthesis and Creating Pores in the Oxide Architecture (2007)

Copper oxide with various morphologies was synthesized by the hydrolysis of Cu(ac)2 with urea under mild hydrothermal conditions. In the synthesis, a series of organic amines with one or two amine groups (monoamine and diamine), including isobutylamine, octylamine (OLA), dodecylamine, octadecylamine (monoamines), ethylenediamine dihydrochloride, and hexamethylenediamine (diamines), was used as the "structure-directing agent". The monoamines led to the formation of one-dimensional (1D) aggregates of the copper oxide precursor particles (Pre-CuO), while the diamines led to the formation of two-dimensional (2D) aggregates. In both cases, the shorter carbon-chain amine molecules showed a stronger structure-directing function than that of the longer carbon-chain amine molecules. Next, in a series of syntheses, OLA was selected for further study, and the experimental parameters were systematically manipulated. When the hydrolysis was adjusted to a very slow rate by coupling the hydrolysis reaction with an esterification reaction, 1D aggregates of Pre-CuO were formed; when the hydrolysis rate was in the middle range, spherical Pre-CuO architectures composed of smaller linear aggregates were formed. However, under the high hydrolysis rates achieved by increasing the precipitation agent (urea) or by conducting the reaction at high temperatures (>/=120 degrees C), only Pre-CuO nanoparticles with a featureless morphology were formed. The formed spherical Pre-CuO architectures can be converted to a porous structure (CuOx) after removing the OLA molecules via calcination. Compared to the 1D and 2D aggregates, this porous architecture is highly thermally stable and did not collapse even after calcination at 500 degrees C. Preliminary results showed that the porous structure can be used both as a catalyst support and as a catalyst for the oxidation of CO at low temperatures.
Isomorphous Substitution of Transition-Metal Ions in the Nanoporous Nickel Phosphate VSB-5 (2004)

The transition-metal-incorporated nickel phosphate molecular sieves (TMI-VSB-5) have been hydrothermally synthesized at 453 K in weak basic conditions under microwave irradiation. By means of X-ray diffraction, inductively coupled plasma (ICP), ultraviolet-visible (UV-vis) diffuse reflectance, and Mössbauer spectroscopies, successful isomorphous (at least partial) substitution of transition-metal ions in the VSB-5 framework has been verified. Characterization results show that the framework structure of nanoporous VSB-5 can accommodate a substantial level of isomorphous substitution of transition-metal ions up to about 10, 5, and 3 atom % for Fe, Mn, and V, respectively, in both octahedral nickel sites (Mn and Fe) and tetrahedral phosphorus sites (V). The isomorphous substitution including the replacement mechanism was studied by not only the change of unit cell parameters but also spectroscopic analysis. The unit cell parameters of TMI-VSB-5 including a unit cell volume and a-axis length relied on the ionic radii difference between the incorporated ion and the original framework ions such as Ni or P (RTMI - RNi or RTMI - RP).
Estimating Traffic Rates in CSMA/CA Networks: A Feasibility Analysis for a Class of Eavesdroppers (2023)

Estimation of transmission rates by a malicious user can serve as a stepping stone to further attacks on the network. In this paper, we aim to investigate the general problem of estimating traffic transmission rates in a CSMA/CA network using a class of passive eavesdropping methods. We consider the case where a single eavesdropper passively monitors all active network nodes but cannot observe all packet transmissions due to spatial-reuse collisions. To enable tractable analysis, we first propose an approximate statistical model that can help the eavesdropper estimate transmission rates with partial measurements under spatial reuse. We next consider a class of eavesdroppers that become increasingly more capable, and develop a framework to demonstrate that two classes of eavesdropper capabilities are sufficient to achieve a consistent transmission rate estimator. We provide numerical tests of our proposed estimators under practical network cases using the NS-3 simulator that validate the theoretical results.
Process Development for Scale-Up of a Novel 3,5-Substituted Thiazolidine-2,4-dione Compound as a Potent Inhibitor for Estrogen-Related Receptor 1 (2014)

The development of a reproducible process for multihundred gram production of (Z)-5-((1-(4-chloro-2-(trifluoromethyl)benzyl)-1H-indazol-5-yl)methylene)-3-((3R,4R)-3-fluoro-1-methylpiperidin-4-yl)thiazolidine-2,4-dione (26), a potent and selective inhibitor of estrogen-related receptor 1 (ERR1), is described. This multihundred gram synthesis was achieved via magnesium perchlorate-catalyzed regioselective epoxide ring-opening of tert-butyl 7-oxa-3-azabicyclo[4.1.0]heptane-3-carboxylate (9) with thiazolidine-2,4-dione (6, TZD) to form a diastereomeric mixture tert-butyl 4-(2,4-dioxothiazolidin-3-yl)-3-hydroxypiperidine-1-carboxylate (17), of which the 3-hydroxyl group was functionally transformed to 3-fluoro derivative 19 after treatment with Deoxo-Fluor. Chiral separation of 19 provided the desired diastereomer (3R,4R)-21 that was converted to the secondary amine 23 TFA salt. Reductive amination of 23 produced the key intermediate N-methyl 24. Knoevenagel condensation of 24 with 1-(4-chloro-2-(trifluoromethyl)benzyl)-1H-indazole-5-carbaldehyde (5) produced the final product 26 in 10% overall yield (99.7% HPLC area% with ≥99.5% de) after a convergent eight synthetic steps with the only column purification being the chiral HPLC separation of 3R,4R-21 from 3S,4S-22.
Outcome of emergency ERCP in the intensive care unit (2011)

There are limited data on the outcome of emergency endoscopic retrograde cholangiopancreatography (ERCP) performed in the intensive care unit (ICU). We sought to assess the frequency, indications, and clinical outcomes of ERCPs performed in ICU patients who were too unstable to be transported to the endoscopy unit. An electronic endoscopy database was used to identify the patients (n = 22) and to assess procedural success, complications, and mortality. The indications for ERCP included suspected biliary sepsis, suspected gallstone pancreatitis, and known choledocholithiasis with cholangitis. Biliary cannulation, which was attempted in all patients, was successful in 19 patients (86 %), and of these 18 (95 %) underwent a technically successful endoscopic therapy. There were no apparent endoscopic complications. Therefore, emergency bedside ERCP in ICU patients, which is primarily performed for the management of suspected biliary sepsis and gallstone pancreatitis, can achieve high technical success rates when performed by experienced endoscopists, although the 30-day mortality rate remains high due to multiorgan dysfunction.
Investigating phoneme-dependencies of spherical voice directivity patterns (2021)

Dynamic directivity is a specific characteristic of the human voice, showing time-dependent variations while speaking or singing. To study and model the human voice's articulation-dependencies and provide datasets that can be applied in virtual acoustic environments, full-spherical voice directivity measurements were carried out for 13 persons while articulating eight phonemes. Since it is nearly impossible for subjects to repeat exactly the same articulation numerous times, the sound radiation was captured simultaneously using a surrounding spherical microphone array with 32 microphones and then subsequently spatially upsampled to a dense sampling grid. Based on these dense directivity patterns, the spherical voice directivity was studied for different phonemes, and phoneme-dependent variations were analyzed. The differences between the phonemes can, to some extent, be explained by articulation-dependent properties, e.g., the mouth opening size. The directivity index, averaged across all subjects, varied by a maximum of 3 dB between any of the vowels or fricatives, and statistical analysis showed that these phoneme-dependent differences are significant.

RhoA/ROCK signaling is essential for multiple aspects of VEGF‐mediated angiogenesis (2010)

The small GTPase RhoA and its downstream effectors, ROCK1 and ROCK2, regulate a number of cellular processes, including cell motility, proliferation, survival, and permeability. Pharmacological inhibitors of the Rho pathway reportedly block angiogenesis; however, the molecular details of this inhibition are largely unknown. We demonstrate that vascular endothelial growth factor-A (VEGF) rapidly induces RhoA activation in endothelial cells (ECs). Moreover, the pharmacological inhibition of ROCK1/2 using 10 microM Y-27632 (the IC(50) for this compound in ECs) strongly disrupts vasculogenesis in pluripotent embryonic stem cell cultures, VEGF-mediated regenerative angiogenesis in ex vivo retinal explants, and VEGF-mediated in vitro EC tube formation. Furthermore, using small interfering RNA knockdown and mouse heterozygote knockouts of ROCK1 and ROCK2, we provide data indicating that VEGF-driven angiogenesis is largely mediated through ROCK2. These data demonstrate that Rho/ROCK signaling is an important mediator in a number of angiogenic processes, including EC migration, survival, and cell permeability, and suggest that Rho/ROCK inhibition may prove useful for the treatment of angiogenesis-related disorders.
A framework for benchmarking entity-annotation systems (2013)

In this paper we design and implement a benchmarking framework for fair and exhaustive comparison of entity-annotation systems. The framework is based upon the definition of a set of problems related to the entity-annotation task, a set of measures to evaluate systems performance, and a systematic comparative evaluation involving all publicly available datasets, containing texts of various types such as news, tweets and Web pages. Our framework is easily-extensible with novel entity annotators, datasets and evaluation measures for comparing systems, and it has been released to the public as open source. We use this framework to perform the first extensive comparison among all available entity annotators over all available datasets, and draw many interesting conclusions upon their efficiency and effectiveness. We also draw conclusions between academic versus commercial annotators.
A tunable impedance surface performing as a reconfigurable beam steering reflector (2002)

We describe a reconfigurable microwave surface that performs as a new kind of beam steering reflector. The surface is textured with an array of tiny resonators, which provide a frequency-dependent surface impedance. By tuning the individual resonators, the surface impedance, and thus the reflection coefficient phase, can be varied as a function of position across the reflector. Using a reflection phase gradient, the surface can steer a reflected beam. As an example, we have built a simple mechanically tuned surface in which physical motion of only 1/100 wavelength generates a sufficient phase gradient to steer a reflected beam by /spl plusmn/16 degrees. To steer to greater angles, the surface can be configured as an artificial microwave grating, capable of /spl plusmn/38 degrees of beam steering. The concept of the tunable impedance surface demonstrated here can be extended to electrically controlled structures, which would permit more elaborate reflection phase patterns, and provide more capabilities, such as the ability to focus or steer multiple beams.
Synchronization Analysis in Physical Layer Network Coding (2009)

Physical-layer Network Coding (PNC) makes use of the additive nature of the electromagnetic (EM) waves to apply network coding arithmetic at the physical layer. With PNC,the destructive effect of interference in wireless networks is eliminated and the capacity of networks can be boosted significantly. This paper addresses a key outstanding issue in PNC: synchronization among transmitting nodes. We first investigate the impact of imperfect synchronization (i.e., finite synchronization errors) in a 3-node network. It is shown that with QPSK modulation, PNC still yields significantly higher capacity than straightforward network coding when there are synchronization errors. Significantly, this remains to be so even in the extreme case when synchronization is not performed at all. Moving beyond a 3-node network, we propose and investigate a synchronization scheme for PNC in a general chain network. At last, numerical simulation verifies that PNC is robust to synchronization errors. In particular, for the mutual information performance, there is about 0.5dB loss without time synchronization and there is at most 2dB loss without phase synchronization.
A YAC Contig Spanning the Blepharophimosis-Ptosis- Epicanthus inversus Syndrome and Propionic Acidemia Loci (1997)

Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is an autosomal dominant condition consisting of congenital dysplasia of the eyelids with a reduced horizontal diameter of the palpebral fissures, droopy eyelids and epicanthus inversus. Two clinical entities have been described: type I and type II. The former is distinguished by female infertility, whereas the latter presents without other symptoms. Both type I and type II were recently mapped on the long arm of chromosome 3 (3q22-q23), suggesting a common gene may be affected. The centromeric and the telomeric limits of this region are well defined between loci D3S1316 and D3S1615, which reside approximately 5 cM apart. Here, we present the construction of a YAC contig spanning the entire BPES locus using 17 polymorphic markers, 2 STS and 28 ESTs. This region of approximately 5 Mb was covered by 31 YACs, and was supported by detailed FISH analysis. In addition, we have precisely mapped the propionyl- CoA carboxylase beta polypeptide (PCCB), the gene mutated in propionic acidemia, within this contig. Apart from providing a framework for the identification of the BPES gene, this contig will also be useful for the future identification of defects and genes mapped to this region, and for developing template resources for genomic sequencing.
Molecular dynamics simulations of ionic aggregates in a coarse%3CU%2B2010%3Egrained ionomer melt. (2010)

Environmental tobacco smoke (ETS) exposure has been shown in general as a major environmental risk factor and deserves attention in vulnerable population groups. The aim of the project is to analyze the relationships among the ETS and behavior and health in 6&minus;15-year-old children in Slovakia. The status of physical and mental health of children in relation to exposure to tobacco smoke was examined in a representative group of 1478 school children. The methods used, included anonymous questionnaires filled in by parents, Columbia Impairment Scale (CIS), Behavior Problem Index (BPI) and anthropometry. The prevalence of ETS exposure is the highest in the capital (27%) and southern cities. A significant association was found between ETS and age, socio-economic status, incompleteness of the family, level of mother&rsquo;s education and a higher prevalence of respiratory diseases (26.7%). The relationships of ETS with emotional (CIS scores &ge; 16) and behavioral functions (BPI score &ge; 14) were significant in children exposed to mother&rsquo;s or father&rsquo;s smoking at home. In the multivariate analysis these associations were not significant; the factors such as income and completeness of the family were dominant. The results showed mostly the predominant impact of social factors on the physical and mental health status of Slovak school children.

Microwave hydrothermal synthesis and gas sensing application of porous ZnO core–shell microstructures (2014)

A ZnO core–shell structure with a movable core inside a hollow shell has been rapidly prepared by an efficient microwave hydrothermal method without any template. The synthesis was performed in an aqueous solution using zinc acetate dihydrate as the precursor. The observations of field emission electron microscopy and transmission electron microscopy showed that these ZnO core–shell structures were composed of numerous primary particles with size of tens of nanometers. A series of time-dependent experiments were carried out in order to have a closer inspection of the evolution processes of such structures. When evaluated as a sensing material for gas sensors, the as-synthesized ZnO core–shell structures displayed a high response towards ethanol and good response-recovery properties.

Utilization of Chicken Eggshell Waste as a Bio-Filler for Thermoplastic Polymers: Thermal and Mechanical Characterization of Polypropylene Filled with Naturally Derived CaCo3 (2015)

The processing and characterization of polypropylene/eggshell composites was the main objective of this study. Natural source-derived calcium carbonate (CaCO 3 ) was extracted from waste chicken eggshell and compounded with polypropylene polymer. The compound was molded using the Extrusion Compression Molding (ECM) process. X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) analysis were conducted on the eggshell to characterize its constituents. The effects of filler loading, 30 wt.% eggshell and 30 wt.% eggshell with 5 wt.% of maleic anhydride grafted polypropylene (MAPP) on the mechanical and thermal properties were studied. The addition of a small amount of MAPP during melt extrusion improved the dispersion and bonding of CaCO 3 particles in polypropylene. 7.49% decrease in tensile strength, 35.51% enhancement in flexural modulus and 66.05% increase in notched Izod impact energy were obtained by adding 30 wt.% eggshell with 5 wt.% MAPP to polypropylene. Adding 30-wt % of eggshell filler and 5 wt.% MAPP to polypropylene delayed the flame propagation time by 99 seconds.
