Self-adaptive high-frequency injection based sensorless control for IPMSM and SynRM (2017)

An auto-tuning and self-adaptation procedure for high-frequency injection (HFI) based position and speed estimation algorithms in IPMSM and SynRM drives is proposed in this paper. Analytical developments show that the dynamics of the high-frequency tracking loop varies with differential inductances, which in turn depend on the machine operating point due to saturation. On-line estimation and adaptation of the small-signal gain of the loop is proposed here, allowing accurate auto-tuning of the sensorless control scheme, even without any a priori knowledge of the machine parameters. Interesting byproducts of this proposal are the possibility for on-line adaptation of the current controllers and of the injected voltage magnitude, leading to important advantages from the performance, loss and acoustic point-of-view. The theoretical basis of the method will be first introduced and the main concept demonstrated by means of simulations. Implementation has been carried out using the hardware of a standard industrial drive and two 2.2 kW prototype IPMSMs. Experimental test results demonstrate the feasibility and effectiveness of the proposal.
Ultra-Drawing of Ultrahigh Molecular Weight Poly (acrylonitrile) (1993)

Dry gel films of ultrahigh molecular weight poly(acrylonitrile) homopolymer, having strong intermolecular forces, have been drawn by solid-state coextrusion in the temperature range from room temperature to 260°C. The effects of solution concentration from which gel was made and extrusion temperature on the extrusion behavior and the structure and properties of drwan films have been studied. The draw-ability of each gel increased with extrusion temperature above the Tg(80°C), reached a maximum at 160°C, and then decreased rapidly above 160°C. The draw-ability of gel also increased with decreasing the solution concentration from which gel was generated. This indicates that the ductility of poly(acrylonitrile), which has strong intermolecular forces and exhibits no crystalline relaxation, is also controlled by the entanglement density, like polyethylene having weak intermolecular interactions. Gel prepared from the lowest concentration of 2 wt% in this work could be extrusion-drawn to draw ratios ≤82 at 160°C. Extrusion temperature markedly affected not only the ductility of gel, but also the efficiency of draw and the formation of flaws at high draw ratios. Thus, the maximum tensile modulus and strength achieved in this work were 20 and 1.0 GPa, respectively.
Microfocused Ultrasound for Nonablative Skin and Subdermal Tightening to the Periorbitum and Body Sites: Preliminary Report on Eighty-Two Patients (2012)

Lax crepey skin is a major unsightly finding throughout the face and body that occurs from chronological aging and environmental photodamage. Surgical lifting procedures are unable to induce sufficient neocollagenesis and also associated with visible scars, risks and recovery time. In this preliminary report, non-invasive delivery of microfocused ultrasonic thermal coagulation points at two levels of the dermis outside the orbital rims was effective in reduction of crepey, wrinkled and sagging skin for about 1 ? years in nineteen treated patients. Matched Orientation Mirror Imaging produced an average brow height elevation of 1 - 2 mm. Microfocused thermal coagulation points at multiple tissue levels also induced tissue tightening and reduction of crepey wrinkled skin in the décolletage, brachium, periumbilicus, inner thigh and knees. Investigator and Subject Global Aesthetic Improvement Scale graded responses that correlated to the severity of the degree of crepiness and laxity. Pain management during the procedure included the use of infiltration of local anesthesia. No permanent adverse events were observed. Further innovations in the current technology are needed for more effective and safer delivery of energy to improve the appearance of crepey and lax tissue in the head, neck and body.

An efficient split-radix FFT algorithm (2003)

In this paper, an efficient split-radix FFT algorithm is proposed for computing the length-2/sup r/ DFT that reduces significantly the number of data transfers, index generations, and twiddle factor evaluations or accesses to the lookup table. It is shown that the arithmetic complexity of the proposed algorithm is no more than that of the existing split-radix algorithm. The basic idea behind the proposed algorithm is that a radix-2 and a radix-8 index maps are used instead of a radix-2 and a radix-4 index maps as in the classical split-radix FFT. In addition, since the algorithm is expressed in a simple matrix form using the Kronecker product, it facilitates an easy implementation of the algorithm, and allows for an extension to the multidimensional case.
Biological Control of Culex Mosquitoes (Diptera: Culicidae) by the Tadpole Shrimp, Triops longicaudatus (Notostraca: Triopsidae) (1991)

Laboratory oviposition choice tests and behavioral observations indicated that the activity of tadpole shrimp, Triops longicaudatus (LeConte), near the water surface deterred gravid Culex quinquefasciatus Say from ovipositing. In the cities of Oasis and Riverside, Calif., tadpole shrimp significantly reduced the abundance of immature mosquitoes (Cx. tarsalis Coquillett and Cx. quinquefasciatus) probably due to lowered oviposition rates, as well as tadpole shrimp predation. Generally, mosquito oviposition rates in field ponds with tadpole shrimp were lower than that of controls, except when tadpole shrimp were very young (4 d after flooding) or when their abundance had declined late in the flooding period. When analyzed by pond, tadpole shrimp size was correlated inversely with abundance; however, differences in size or abundance did not affect their capacity to reduce mosquito populations.
Modified laparoscopic cervicoisthmic cerclage in early pregnancy for refractory cervical incompetence: A case report (2019)

Modified laparoscopic cerclage was developed as an easy laparoscopic approach during pregnancy, with sutures placed lateral to the uterine vessels. To the best of our knowledge, its successful use in the first trimester has not been reported in Japan. Additionally, there are no published data on chronological assessment of feto-placental circulation using Doppler. Here, we present the case of a 31-year-old Japanese woman (gravida 2, para 1) with refractory cervical incompetence who had a history of preterm birth at 32 weeks of gestation and cervical conization. Modified laparoscopic cervicoisthmic cerclage was performed. Doppler findings showed normal feto-placental circulation before and after the procedure. Her pregnancy progressed uneventfully with no significant feto-placental circulation or obstetric complications, and the baby showed normal growth. Elective cesarean section was performed at 37 + 0 weeks' gestation. Modified laparoscopic cervicoisthmic cerclage is suggested as one of the treatment methods for pregnant women with refractory cervical incompetence.
Interactive broadcast radio architecture (2003)

Multimedia systems, such as interactive broadcast and satellite radios, have increasingly been demanding higher performance CPUs and higher performance DSPs to process the received data in real-time. In many cases, the performance of a general-purpose processor is not adequate, and this creates a demand for a system-on-chip device that processes the multimedia tasks efficiently and independently. A device, which integrates TI DSP and ARM processor cores, is an ideal solution for implementing interactive multimedia systems. One concept proposed here, utilizing this device, is an interactive broadcast radio system where the analog radio broadcast signal is received and real-time MP3 data is encoded/decoded to enable time shifting capabilities such as hard disk recording, pause, fast forward, and rewind. This architecture also allows voice command recording of driving directions that enables productizing a low-cost navigation system.
Selfish optimization and collective learning in populations (2021)

A selfish learner seeks to maximize their own success, disregarding others. When success is measured as payoff in a game played against another learner, mutual selfishness typically fails to produce the optimal outcome for a pair of individuals. However, learners often operate in populations, and each learner may have a limited duration of interaction with any other individual. Here, we compare selfish learning in stable pairs to selfish learning with stochastic encounters in a population. We study gradient-based optimization in repeated games like the prisoner's dilemma, which feature multiple Nash equilibria, many of which are suboptimal. We find that myopic, selfish learning, when distributed in a population via ephemeral encounters, can reverse the dynamics that occur in stable pairs. In particular, when there is flexibility in partner choice, selfish learning in large populations can produce optimal payoffs in repeated social dilemmas. This result holds for the entire population, not just for a small subset of individuals. Furthermore, as the population size grows, the timescale to reach the optimal population payoff remains finite in the number of learning steps per individual. While it is not universally true that interacting with many partners in a population improves outcomes, this form of collective learning achieves optimality for several important classes of social dilemmas. We conclude that naïve learning can be surprisingly effective in populations of individuals navigating conflicts of interest.
Phosphorylated Peptide Functionalization of Lanthanide Upconversion Nanoparticles for Tuning Nanomaterial–Cell Interactions (2016)

Peptide modification of nanoparticles with high efficiency is critical in determining the properties and bioapplications of nanoparticles, but the methodology remains a challenging task. Here, by using the phosphorylated linear and cyclic peptide with the arginine-glycine-aspartic acid (RGD) targeting motifs as typical examples, the peptides binding efficiency for the inorganic metal compound nanoparticles was increased significantly after the phosphorylation treatment, and the modification allowed for improving the selectivity and signal-to-noise ratio for cancer targeting and reduced the toxicity derived from nonspecific interactions of nanoparticles with cells owing to the higher amount of phosphopeptide binding. In addition, molecular dynamics (MD) simulations of various peptides on inorganic metal compound surfaces revealed that the peptide adsorption on the surface is mainly driven by electrostatic interactions between phosphate oxygen and the polarized interfacial water layer, consistent with the experimental observation of the strong binding propensity of phosphorylated peptides. Significantly, with the RGD phosphopeptide surface modification, these nanoparticles provide a versatile tool for tuning material-cell interactions to achieve the desired level of autophagy and may prove useful for various diagnostic and therapeutic applications.
A complete algorithm for designing passive fences to orient parts (1997)

Reviews Peshkin and Sanderson (1988) who showed that parts can be aligned as they move on a conveyor belt against a passive sequence of fences. Describes the first complete algorithm to design such sequences for a given convex polygonal part. The algorithm is complete in the sense that it is guaranteed to find a design if one exists and to terminate with a negative report otherwise. Based on an exact breadth‐first search of the design space, the algorithm is also guaranteed to find the design requiring the fewest fences. Describes the algorithm and compares results with those previously reported. Conjectures that a fence design exists to orient any convex polygonal part defined by a sequence of rational vertices.

Monoclonal Antibody for Calcitriol (l α,25-Dihydroxyvitamin D3) (1985)

Hybridoma cell lines secreting antibodies for vitamin D3 metabolites have been generated by fusing splenocytes from BALB/c mice immunized with 3 beta-glutaryl-25-hydroxyvitamin D3 conjugated to bovine serum albumin (3 beta-glu-25-OH-D3-BSA) and Sp2/O-Ag14 myeloma cells. Purification of monoclonal antibodies from culture media or ascites fluids was accomplished by procedures including affinity chromatography on Protein A-Sepharose 4B. Each monoclonal antibody was analyzed as to its affinity and specificity by equilibrium dialysis and an enzyme immunoassay (EIA) based on a double antibody system. It was demonstrated that clone 1C2-60 produced an antibody highly specific to 1 alpha,25-dihydroxyvitamin D3 (calcitriol), and the clone 2B3-66 antibody was reactive to 25-hydroxyvitamin D3 and similar structural compounds. These two monoclonal antibodies produced by 1C2-60 and 2B3-66 were determined to belong to the IgG2a class, and their affinity constants (Ka) with 3 beta-glu-25-OH-D3 were demonstrated to be 3.6 X 10(9) M-1 and 2.9 X 10(9) M-1, respectively, at 4 degrees C. The characteristics of these monoclonal antibodies were compared with those of conventional antibodies raised in mice and rabbits. Finally, by using monoclonal antibody 1C2-60, a sensitive EIA has been developed that can detect 10 pg of calcitriol.
Near‐ultraviolet laser diodes for brilliant ultraviolet fluorophore excitation (2015)

Although multiple lasers are now standard equipment on most modern flow cytometers, ultraviolet (UV) lasers (325-365 nm) remain an uncommon excitation source for cytometry. Nd:YVO4 frequency-tripled diode pumped solid-state lasers emitting at 355 nm are now the primary means of providing UV excitation on multilaser flow cytometers. Although a number of UV excited fluorochromes are available for flow cytometry, the cost of solid-state UV lasers remains prohibitively high, limiting their use to all but the most sophisticated multilaser instruments. The recent introduction of the brilliant ultraviolet (BUV) series of fluorochromes for cell surface marker detection and their importance in increasing the number of simultaneous parameters for high-dimensional analysis has increased the urgency of including UV sources in cytometer designs; however, these lasers remain expensive. Near-UV laser diodes (NUVLDs), a direct diode laser source emitting in the 370-380 nm range, have been previously validated for flow cytometric analysis of most UV-excited probes, including quantum nanocrystals, the Hoechst dyes, and 4',6-diamidino-2-phenylindole. However, they remain a little-used laser source for cytometry, despite their significantly lower cost. In this study, the ability of NUVLDs to excite the BUV dyes was assessed, along with their compatibility with simultaneous brilliant violet (BV) labeling. A NUVLD emitting at 375 nm was found to excite most of the available BUV dyes at least as well as a UV 355 nm source. This slightly longer wavelength did produce some unwanted excitation of BV dyes, but at sufficiently low levels to require minimal additional compensation. NUVLDs are compact, relatively inexpensive lasers that have higher power levels than the newest generation of small 355 nm lasers. They can, therefore, make a useful, cost-effective substitute for traditional UV lasers in multicolor analysis involving the BUV and BV dyes.
Influence of protein flexibility and peptide conformation on reactivity of monoclonal anti-peptide antibodies with a protein alpha-helix. (1987)

Monoclonal antibodies against an alpha-helical region of the iron-containing, oxygen-binding protein myohemerythrin were isolated following immunization of mice with either the whole protein or a peptide homolog of the helix. Three distinct epitopes within the myohemerythrin helix were identified. The individual residues within two of these epitopes that were essential for antibody binding were determined by measuring antibody binding to a set of peptides in which each amino acid of the epitope was replaced in turn by each of the other 19 amino acids. Hydrophilic residues that are exposed in the native conformation and buried, hydrophobic residues were both shown to be irreplaceable, suggesting their direct involvement in antibody binding. The influence of antigen conformation on antibody binding to these amphipathic epitopes was assessed by measuring the relative affinities of the antibodies for peptides, intact protein, and apoprotein. All of the antibodies bound to apoprotein better than to native protein, indicating that relaxation of the native structure by removal of the iron center increases antibody affinity for myohemerythrin. However, not all of the antibodies tested bound to peptides better than to protein, suggesting that increased antigen flexibility is not always sufficient to maximize antibody binding. Antibody binding to peptides appeared to also be influenced by the ability of the peptides to attain secondary structure at the epitopes, either alone or due to carrier influences.
Recurrent Epithelioid Hemangioma of the Bony Pelvis Responding to Propranolol (2019)

Epithelioid hemangioma is an uncommon benign vascular neoplasm which can arise in bone. Resection is generally curative, but occasionally lesions recur and recurrence after surgery can be morbid and destructive. Recent case reports have described the effective use of oral propranolol to control recurrent epithelioid hemangioma of the orbit. We report the case of a 26 year old man with recurrent aggressive osseous epithelioid hemangioma in the pelvis of which has been controlled for over a year with outpatient propranolol monotherapy.
Arousal and attention deficits in patients with tinnitus. (2006)

We investigated the effects of tinnitus on measures of arousal and attention at various levels of the neuraxis to derive a profile of the pathophysiology of tinnitus. Individuals with tinnitus of at least 6 months' duration (14 male, 15 female) and healthy controls (14 male, 21 female) were tested for arousal and habituation to repetitive stimulation at the brainstem-thalamus level by measuring the P50 potential, a scalp-recorded, auditory-evoked response, using pairs of click stimuli. We used the psychomotor vigilance task, a reaction-time test, to assess attentional processes mediated by thalamocortical functions. We then correlated deficits in arousal and attention, as measured by these tests, with perceived tinnitus severity. Results showed no difference between tinnitus patients and controls in level of arousal or habituation to repetitive sensory stimulation, as measured by the amplitude of the P50 potential and the ability to suppress a second, closely paired stimulus, respectively. However, reaction-time assessments showed that patients with tinnitus have attentional deficits relative to controls (p = .02). We found no significant correlation between sleep disturbance or tinnitus severity and reaction-time testing.
Network structure-based decorated CPA@CuO hybrid nanocomposite for methyl orange environmental remediation (2021)

A unique network core-shell hybrid design-based cross-linked polyaniline (CPA), which was coated with CuO nanoparticles (NPs) and decorated with nitrogen-doped SWCNT/GO/cellulose N-SWCNTS-GO-CE, has been fabricated using the oxidative polymerization technique. This hybrid nanocomposite shows excellent photocatalytic degradation and an acceptable adsorption capability for Methyl Orange (MO) dye in aqueous solutions with a very slight effect for the N-SWCNTS-GO-CE CuO component. The prepared nanocomposites were used for the removal of a carcinogenic and noxious dye, Methyl Orange, from aqueous samples under various adsorption conditions. Approximately 100% degradation of 10 mg/L of Methylene orange dye was observed within 100 min at pH 6.0 using 50 mg/L CPA/N-SWCNTS-GO-CE/CuO nanocomposite under UV radiation. Additionally, significant factors were investigated on the degradation process including the contact time, MO initial concentration (C<sub>i</sub>), solution pH, and dosage of the CuO nanocomposite. All investigated experiments were performed under UV radiation, which provided significant data for the MO degradation process. Furthermore, the recovery of the nanocomposite was studied based on the photocatalytic process efficiency. The obtained data provide the high opportunity of reusing CPA/N-SWCNTS-GO-CE/CuO nanocomposite for numerous photocatalytic processes. The CPA/N-SWCNTS-GO-CE/CuO nanocomposite was prepared via chemical oxidative copolymerization of polyaniline (PANI) with p-phenylenediamine (PPDA) and triphenylamine (TPA) in the presence of N-SWCNTS-GO-CE and CuO NPs. The morphology, structure and thermal properties of the CPA/N-SWCNTS-GO-CE/CuO nanocomposite were investigated using various techniques, including FTIR, XRD, RAMAN, SEM, MAP, EDX, TEM, TGA and DTG. Therefore, CPA/N-SWCNTS-GO-CE/CuO nanocomposite can be effectively used as a convenient and reusable adsorbent to remove hazardous dye from wastewater.
Mechanistic Studies of 1-Deoxy-D-Xylulose-5-Phosphate Synthase from Deinococcus radiodurans (2018)

The non-mevalonate dependent (NMVA) pathway for the biosynthesis of isopentenyl pyrophosphate and dimethylallyl pyrophosphate is the sole source of these terpenoids for the production of isoprenoids in the apicomplexan parasites, in many eubacteria, and in plants. The absence of this pathway in higher organisms has opened a new platform for the development of novel antibiotics and anti-malarials. The enzyme catalyzing the first step of the NMVA pathway is 1-deoxy-D-xylulose-5-phosphate synthase (DXPS). DXPS catalyzes the thiamine pyrophosphate- and Mg (II)-dependent conjugation of pyruvate and D-glyceraldehyde-3-phosphate to form 1-deoxy-D-xylulose-5-phosphate and CO<sub>2</sub>. The kinetic mechanism of DXPS from <i>Deinococcus radiodurans</i> most consistent with our data is random sequential as shown using a combination of kinetic analysis and product and dead-end inhibition studies. The role of active site amino acids, identified by sequence alignment to other DXPS proteins, was probed by constructing and analyzing the catalytic efficacy of a set of targeted site-directed mutants.
