Scanning electron microscopic evaluation of the successful sterilization of Lucilia cuprina (Wiedemann) utilized in maggot debridement therapy (mdt). (2011)

In Malaysia, maggot debridement therapy (MDT) utilizes maggots of Lucilia cuprina (Wiedemann) to debride necrotic tissue from wound surface, reduce bacterial infection and therefore, enhance wound healing process. To evaluate the sterility of the sterile maggots produced after sterilization process before delivering onto patient wounds. Sterility of sterile maggots is crucial in ensuring the safe usage of MDT and patient's health. Eggs of L. cuprina collected from a laboratory colony were divided into treated group (sterilized) and control group (non-sterilized). Treated group underwent sterilization while eggs from control group were allowed to hatch without sterilization. Sodium hypochlorite and formaldehyde were the main disinfectants used in this sterilization process. Scanning electron microscope (SEM) was used to examine and ascertain the sterility of sterile maggots. SEM results showed that all sterilized L. cuprina eggs and maggots achieved sterility and all were cleared from bacterial contamination. In contrast, all non-sterilized eggs and maggots were found to be colonized by microorganisms. Sterilization method employed to sterilize eggs and maggots used in Malaysia MDT was proven successful and MDT is safe to be used as wound management tools.
PROTEINS IN SERUM AND CEREBROSPINAL FLUID IN DEMENTED PATIENTS (2009)

Sixteen plasma proteins, including the immunoglobulins, were determined in cerebrospinal fluid (CSF) and serum from 12 demented patients. Furthermore, the total protein content was measured, haptoglobin was typed and serum was tested for precipitins against water-extractable human brain antigens. No specific quantitative changes in the plasma proteins in either CSF or serum were found. In CSF, an increased permeability of the blood-liquor-barrier, reflected in raised CSF total protein values, dominated the picture. In serum, no changes specific to brain atrophy were found, neither were any precipitins against human brain antigens revealed.

Numerical and Experimental Analyses of a Smart Fin Using Piezoelectric Actuator (2018)

This paper introduces the comprehensive design of a thin piezoelectric-driven fin. Because of its hinge and flexible spar component having a low torsional stiffness with a thin composite actuator, the divergence speed is also predicted to be low, which is ascertained by a wind-tunnel test. As the divergence is related to the first pitch mode, the control input magnitude may be significantly reduced at the divergence speed. An improved design of the fin is also suggested to ensure its operability up to Mach 0.6. Its equivalent aeroelastic analysis is conducted by rational function approximation, and a linear quadratic regulator control law is designed using a steady-state Kalman filter with disturbance and an integral state for the tip deflection state augmentation. Both open- and closed-loop simulations are conducted while considering the input voltage saturation and other nonlinear losses in the actuator. In the relevant simulation, it is shown that a sufficient amount of pitch rotation can be achieved without any overshoots while consuming half of the zero-load voltage. Additionally, an external disturbance such as a gust can be sufficiently suppressed by increasing the closed-loop bandwidth.

Geometrically Exact Nonlinear Extended-Reissner/Mindlin Shells: Fundamentals, Finite Element Formulation, Elasticity (2009)

Extended Reissner/Mindlin shell kinematics are used to develop an exact shell that makes no further approximations on the deformation or strain. The formulation is fully tensorial. A three-dimensional isoparametric element is used as the reference configuration. The FE approximation introduces nodes on the mid-surface of the isoparametric element, with the thickness having a separately defined interpolation. The variational formulation is based on the nominal stress tensor. Isotropic linear and nonlinear elastic shells are constructed that use p-type interpolation along the director. The formulation is exact, resulting in nonlinear elements showing better characteristics in comparison to other such elements.

Characterization of overall ceramide species in human stratum corneum (2008)

Ceramides (CERs) in human stratum corneum (SC) play physicochemical roles in determining barrier and water-holding functions of the skin, and specific species might be closely related to the regulation of keratinization, together with other CER-related lipids. Structures of those diverse CER species, however, have not been comprehensively revealed. The aim of this study was to characterize overall CER species in the SC. First, we constructed 3D multi-mass chromatograms of the overall CER species, based on normal-phase liquid chromatography (NPLC) connected to electrospray ionization-mass spectrometry (ESI-MS) using a gradient elution system and a postcolumn addition of a volatile salt-containing polar solvent. The CERs targeted from the 3D chromatograms were structurally analyzed using NPLC-ESI-tandem mass spectrometry (MS/MS), which resulted in the identification of 342 CER species in the inner forearm SC. This led to the discovery of a new CER class consisting of alpha-hydroxy fatty acid and dihydrosphingosine moieties, in addition to the 10 classes generally known. The results also revealed that those CERs contain long-chain (more than C(18))-containing sphingoids and a great number of isobaric species. These novel results will contribute not only to physiochemical research on CERs in the SC but also to lipidomics approaches to CERs in the skin.
MTouch: An Automatic Fault Detection System for Desktop FFF 3D Printers Using a Contact Sensor (2021)

Desktop fused filament fabrication (FFF) 3D printers have been growing in popularity among hobbyist and professional users as a prototyping and low-volume manufacturing tool. One issue these printers face is the inability to determine when a defect has occurred rendering the print unusable. Several techniques have been proposed to detect such defects but many of these approaches are tailored to one specific fault (e.g., filament runout/jam), use expensive hardware such as laser distance sensors, and/or use machine vision algorithms which are sensitive to ambient conditions, and hence can be unreliable. This paper proposes a versatile, reliable, and low-cost system, named MTouch, to detect millimeter-scale defects that tend to make prints unusable. At the core of MTouch is an actuated contact probe designed using a low-power solenoid, magnet, and hall effect sensor. This sensor is used to check for the presence, or absence, of the printed object at specific locations. The MTouch probe demonstrated 100% reliability, which was significantly higher than the 74% reliability achieved using a commercially available contact probe (the BLTouch). Additionally, an algorithm was developed to automatically detect common print failures such as layer shifting, bed separation, and filament runout using the MTouch probe. The algorithm was implemented on a Raspberry Pi mini-computer via an Octoprint plug-in. In head-to-head testing against a commercially available print defect detection system (The Spaghetti Detective), the MTouch was able to detect faults 44% faster on average while only increasing the print time by 8.49%. In addition, MTouch was able to detect faults The Spaghetti Detective was unable to identify such as layer shifting and filament runout/jam.
Outage performance of two users cooperative network coding (2009)

Cooperative communications has emerged as an efficient realization of multiple input and multiple output (MIMO) systems. To reap the benefits of cooperative communications we follow the block-Markov code book structure. Recently a low cost and efficient operational implementation of block-Markov coding, using network coding, has been proposed. In this paper, we derive the closed form expression for outage probability of that network coded cooperative communications scheme. We take information theoretic approach to define the outage probability. For comparison purpose, we also discuss the outage results of space-time (ST) coded cooperation, and the cooperation based on repetition. With numerical results, we show that the network coded cooperation, based on block-Markov code book structure, performs better than ST and repetition based cooperation, in terms of coding gain, while offering the same diversity gain as the other two.
Further results on optimally weighted subspace based blind channel estimation (2002)

Subspace based identification of model parameters requires a low rank data model. To obtain such a model it is common to collect several snapshots of the observed vector valued sequence in a larger vector. In many cases, this "window" procedure results in a new vector valued process which can be viewed as originating from a low rank data model. When studying the performance of weighted subspace based techniques this window procedure complicates both the analysis and the implementation. In this paper an attempt is made to clarify the theoretical and numerical difficulties when applying weighting in such scenarios.

A dicarboxylate transporter on the peribacteroid membrane of soybean nodules (1988)

Using preparations of peribacteroid membrane (PBM)‐enclosed bacteroids from soybean root nodules, we show here that the PBM possesses a dicarboxylate transporter capable of mediating a rapid flux of dicarboxylate anions, such as malate and succinate, to the bacteroids inside the nodule. The transporter has a higher affinity for the monovalent malate anion than for the succinate anion ( K m = 2 and 15 μM, respectively) although the V max for malate − appears to be lower than for succinate − ( V max = 11 and 30 nmol·min −1 ·mg protein −1 , respectively).
Adaptive sampling and processing of ultrasound images (2001)

An AM-FM video image representation is developed and applied to M-mode ultrasound. The AM-FM representation describes the video in terms of an AM-FM series expansion. For estimation, the fundamental AM-FM harmonic is estimated using a collection of bandpass filters that are adaptively selected so that one with the maximum response is selected. For each bandpass filter, the output image is downsampled depending on the spectral support of the filter. Using results from multidimensional frequency modulation theory, it is shown that a fast separable implementation is possible. In turn, good estimates are obtained from a collection of only two separable, bandpass filters approximated with just a small number of 11 coefficients and the recently developed SIMD-FFT. The fundamental AM-FM harmonic is seen to capture the essential structure of the image and simple thresholding of the amplitude estimate yields very good segmentation results.
Olfaction after Endoscopic Endonasal Ethmoidectomy (1993)

A detailed preoperative and postoperative examination of the olfactory function of 111 patients with chronic polypoid ethmoiditis was carried out. Eighty-seven patients required a complete endoscopic endonasal sphenoethmoidectomy. In 24 patients an endoscopic partial resection of the ethmoidal cell system was performed. Before surgery a normosmia was ascertained in 39 patients (35%). Thirty-four patients (31%) were hyposmic, and 38 patients (34%) suffered from anosmia. In the postoperative olfactory function test 89 patients (80%) had a normal sense of smell; 13 patients (12%) showed hyposmia, and nine patients (8%) experienced anosmia. Seventy-eight percent of the patients with impaired olfactory function had marked improvement after the operation. Patients who had previously undergone a polypectomy had a less favorable prognosis. None of the preoperatively normosmic patients became hyposmic or even anosmic after endoscopic sinus surgery. The sense of smell of only two of the 34 patients with preexisting hyposmia worsened after surgery. The postoperative size of the middle nasal turbinate did not correlate with the ability to smell. More important was the accessibility of the olfactory cleft.
Effect of Chlorine Substituents on the Photovoltaic Properties of Monocyanated Quinoxaline-Based D–A-Type Polymers (2023)

A string of monocyanated quinoxaline (Qx)-based D-A-type polymers systematically decorated with electron-attracting chlorine (Cl) atoms was created for use in non-fullerene polymer solar cells (PSCs). First, coupling of the benzodithiophene (BDT) donor and Qx acceptor with the strong electron-attracting cyano (CN) unit at its 5-position yielded the monocyanated reference polymer PB-CNQ. Subsequently, the additional Cl atoms were separately or simultaneously incorporated into the thiophene side groups of the BDT donor and Qx acceptor to create other objective polymers, PBCl-CNQ, PB-CNQCl, and PBCl-CNQCl. The Cl substituents on the BDT donor and Qx acceptor are represented by the names of the polymers. Owing to the favorable contributions of Cl substituents, the inverted-type non-fullerene PSCs based on partially chlorinated PBCl-CNQ (12.80%) and PB-CNQCl (13.93%) exhibited better power conversion efficiencies (PCEs) than the device based on unchlorinated reference PB-CNQ (11.19%). However, a significantly reduced PCE of 9.84% was observed for the device based on PBCl-CNQCl, in which Cl atoms were loaded on both the BDT donor and Qx acceptor at the same time. Hence, these results reveal that optimization of the number and position of Cl substituents in monocyanated Qx-based polymers is essential for enhancing their photovoltaic nature through the synergistic effects between two strong electron-attracting CN and Cl substituents.

Microsporidia in Insects (2014)

This chapter highlights the biological and life cycle features of entomogenous microsporidia and provides some basic information on their taxonomic distribution. The development of all insect-parasitic microsporidia is restricted to the cytoplasm of the host cell. The development of all insect-parasitic microsporidia is restricted to the cytoplasm of the host cell. Specialized relationships between microsporidia and the host at the cellular level have been termed xenomas. Weiser distinguished two main types of xenomas in insects, syncytial and neoplastic. The chapter presents the major and minor pathways of transmission for insect microsporidia. Alternatively, the criteria used to establish the genera of microsporidia from aquatic insects may not truly reflect phylogenetic diversity but adaptations to specific habitats and host systems. A section lists a few genera for which insects are not the type hosts. This is because many species have been reported to occur in insects (such as Thelohania, Pleistophora) or because there are possible links to insect microsporidia (such as Trichotuzetia). Finally, the chapter provides diagnostic information which is primarily restricted to the features of sporulation and the spore, with the addition of distinguishing life cycle characteristics when available. The type host and species are given followed by comments on distribution and other matters deemed of importance.
SWANA/NREL/DOE landfill methane model development project (1996)

Landfill methane models are widely used to project landfill methane (gas) generation and recovery, as well as landfill emissions to the atmosphere. While several models are used in the landfill gas industry and elsewhere, their {open_quotes}validation{close_quotes} is still, at best, limited. Validation is, simply, adjusting model parameters so that models best project methane recovery field data, or else, demonstrating that models project methane recovery actually experienced. Limited data have been used to develop most models. In addition, models have generally validated methane recovery against projections over relatively short intervals or at only single {open_quotes}points in time{close_quotes} whereas comparisons over longer terms would be desirable. Thus, confidence limits to be assigned to model projections are in large part unknown. In addition, failures of models have been (if anecdotally) reported. In some cases, energy equipment has been installed and left idle reportedly because landfill gas has been less than expected. In light of this situation, this project`s purpose has been to verify and validate models based on data from a greater number of landfills in the past, using gas recovery data over longer terms (several years when possible). Another objective is to use these data to develop a better estimate of keymore » parameters, yield and kinetic coefficients, and associated confidence limits which may be assigned to model projections.« less
Dopant Transport in Tungsten Silicide Buried Layers for Application in SSOI (2010)

The rapid diffusion of phosphorus and boron in WSi2 has been characterized using a novel Schottky Barrier test structure. Diffusivity of both dopant species was about 4-5 orders of magnitude higher than that reported in polycrystalline silicon. The dopant diffusivity is strongly dependent on the silicide morphology. Diffusivity measured in low temperature pre-annealed silicide is approximately an order of magnitude higher than in silicide pre-annealed at 1050°C. The dopant diffusivity in oxide lined silicide test structures was 3-4.3x10-10 cm2 s-1 at 900°C while polycrystalline silicon lined structures exhibited a higher value at 900°C of 1.5x10-9 cm2s-1. This is attributed primarily to greater segregation of dopant to the oxide-silicon interface compared to the polysilicon-silicide interface. Boron exhibited a higher diffusivity in WSi2 with diffusivity in the range 4x10-9 cm2s-1 - 1x10-8 cm2s-1 at 900°C.
Proceedings: Cell Therapies for Parkinson's Disease From Discovery to Clinic (2014)

In March 2013, the California Institute for Regenerative Medicine, in collaboration with the NIH Center for Regenerative Medicine, held a 2-day workshop on cell therapies for Parkinson's disease (PD), with the goals of reviewing the state of stem cell research for the treatment of PD and discussing and refining the approach and the appropriate patient populations in which to plan and conduct new clinical trials using stem cell-based therapies for PD. Workshop participants identified priorities for research, development, and funding; discussed existing resources and initiatives; and outlined a path to the clinic for a stem cell-based therapy for PD. A consensus emerged among participants that the development of cell replacement therapies for PD using stem cell-derived products could potentially offer substantial benefits to patients. As with all stem cell-based therapeutic approaches, however, there are many issues yet to be resolved regarding the safety, efficacy, and methodology of transplanting cell therapies into patients. Workshop participants agreed that designing an effective stem cell-based therapy for PD will require further research and development in several key areas. This paper summarizes the meeting.
Single Cell Assessment of Allergen-Specific T Cell Responses with MHC Class II Peptide Tetramers: Methodological Aspects (2008)

MHC class II peptide tetramers are valuable tools to assess allergen-specific T cell responses, both qualitatively and quantitatively. Selection of a high-affinity T cell epitope, as well as optimization of in vitro stimulation conditions to expand rare T cell progenitors are critical success factors in those analyses.
