Low torque ripple tooth coil windings multi‐3‐phase machines: design considerations and validation (2019)

In multi‐ n ‐phase machines, the n ‐phases are grouped in separated stars. A particular subcategory of multi‐ n ‐phase machines is the multi‐3‐phase machines. This study presents the design considerations and their validation for tooth coil wound multi‐3‐phase machines. A generic algorithm to design multi‐3‐phase machines is proposed. Although this study mainly focuses on multi‐3‐phase machines the approach is generalised and is applicable to any multi‐ n ‐phase machine. The resulting machines exhibit a low torque ripple value, and a mathematical formulation is proposed in order to justify this behaviour. All the multi‐3‐phase machines designed according to the proposed algorithm can be studied, and directly compared, thanks to the generalised harmonic formulation of the stator MMF and the torque performances here proposed. This study is enriched with some design hints useful to realise a machine with low mutual coupling between phases, and some considerations that can help the machine designer in the choice of the number of poles. The design algorithm is applied for the design of a triple‐3‐phase PM‐inset machine solution, with nine slots ten poles. The performances, evaluated by finite element analysis and experimental analysis, demonstrate the effectiveness of the design algorithm proposed in a very simple structure machine.
Scaffolds for the manufacture of cultured meat (2021)

The cultured meat market has been growing at an accelerated space since the first creation of cultured meat burger back in 2013. Substantial efforts have been made to reduce costs by eliminating serum in growth media and improving process efficiency by employing bioreactors. In parallel, efforts are also being made on scaffolding innovations to offer better cells proliferation, differentiation and tissue development. So far, scaffolds used in cultured meat research are predominantly collagen and gelatin, which are animal-derived. To align with cell-based meat vision i.e. environment conservation and animal welfare, plant-derived biomaterials for scaffolding are being intensively explored. This paper reviews and discusses the advantages and disadvantages of scaffold materials and potential scaffolding related to scale-up solution for the production of cultured meat.
Reconnaissance geologic map of the west half of the Solomon quadrangle, Alaska (1972)

The Solomon quadrangle adjoins the Bering Sea east of Nome, Alaska. It has a common west border with the Nome quadrangle (Sainsbury and others, 1972b) and a common north border with the Bendeleben 1:250,000- scale quadrangle.Part of the area was mapped by Smith (1910), who discussed the rocks in some detail. The rocks mapped by Smith were remapped in 1971 along with the unmapped part of the west half of the Solomon quadrangle. Maps covering half the area of the present report have been issued in preliminary form at a scale of 1:63,360 (Sainsbury and others, 1972, 1972a). Consequently, only a brief text accompanies this map.The east half of the Solomon quadrangle has been mapped by Thomas P. Miller, U.S. Geological Survey (unpublished). Mapping techniques of the various workers led to different maps and results; hence the map of the west half is presented only in preliminary form- a final compilation of the entire Solomon quadrangle may incorporate changes.

Usher Syndrome and Color Vision (2018)

The examination of color vision in patients with USH shows a significant difference in the pattern of color vision loss in USH1 and USH2 patients, but not in the severity of the loss. In USH2, we find a correlation between patient age and the degree and the polarity of the loss. These results may be due to differences in the pathogenesis of retinal dystrophy in USH1 and USH2.
Determination of grain boundary rotation parameters from Kikuchi patterns. II. Experimental optimization of the analysis of grain boundary orientation relationships and verification of the accuracy of the proposed method (1983)

The use of an advanced electron optical method for the experimental determination of grain boundary orientation relationships is demonstrated in connection with the study of structural b.c.c. steel after large degree of high temperature deformation. Furthermore, the accuracy of the previously proposed analytical method[1] is experimentally verified using two different approaches based on (1) the tilting of the foil and on (2) the multiplication test using rotation matrices of three grain boundaries of a triple junction. Die Benutzung einer entwickelten elektro-optischen Methode für die experimentelle Bestimmung der Orientierungsverhältnisse der Korngrenzen wird in Verbindung mit Untersuchungen eines kubisch raumzentrierten Stahls nach grober Hochtemperaturdeformation dargestellt. Ferner wird die Genauigkeit der früher dargestellten Methode [1] experimentell mittels zweier verschiedener Methoden nachgewiesen: (1) durch Neigung der Dünnschicht und (2) durch Multiplizierungstest mit Rotationsmatrizen von drei Korngrenzen im Tripelpunkt.

STED lithography in microfluidics for 3D thrombocyte aggregation testing (2021)

Three-dimensional photopolymerization techniques such as multiphoton polymerization lithography (MPL) and stimulated emission depletion (STED) lithography are powerful tools for fabricating structures in the sub-µm range. Combining these techniques with microfluidics enables us to broaden the range of their applications. In this study, we show a microfluidic device enhanced with MPL structures carrying STED-lithographically written nanoanchors that promote binding of the von Willebrand factor (vWF). The density of vWF is adjusted by varying the number of the nanoanchors on the 3D structures. This allows us to study the impact of the density of vWF on the activation of thrombocytes. The activation of the thrombocytes seems to decrease with the density of vWF on the 3D scaffolds inside the microfluidic channels.

T7 Linear Amplification of DNA (TLAD) for Microarrays (2019)

Round A/Round B amplification has been used extensively in genomic localization analysis and appears to work quite well for typical microarray applications in which DNA is sheared by sonication to ∼500 bp. For amplification of material <500 bp in size, however, T7 linear amplification of DNA (TLAD) is preferred because it more accurately maintains uniform representation of short DNA fragments. Amplification of double-stranded DNA by TLAD begins with the addition of a 3' tail of poly-thymidine to DNA by TdT. Second, the Klenow fragment of <i>Escherichia coli</i> DNA polymerase is used, along with a T7-poly(A) primer, to generate a complementary strand that carries a 5' T7 primer. Finally, extension of the original T-tailed DNA strand yields a template suitable for T7-based transcription, which generates amplified RNA (aRNA). This technique avoids the "jackpotting" issues observed with PCR, in which an early amplification event leads to disproportionate representation of a particular sequence, because PCR follows exponential kinetics, whereas transcription is a linear amplification method.
Design Optimization of 1,3-Diphospha-2,4-diboretane Diradicals (2002)

Substantial control over frontier orbital splittings in 1,3-diphospha-2,4-diboretanes can be achieved by variation of phosphorus substituents R, thereby enhancing diradical character (see scheme; e.g. R=SiMe3, R′=tBu).
Thyroid disease - Common clinical scenarios, or how to make it through thyroid clinic day in nuclear medicine (2006)

1025 In all age groups, there are common clusters of scant-to-minimal clinical histories that will allow relatively specific diagnoses to be made or confirmed by thyroid uptake and scan studies. Adults often present with evidence of thyroid overactivity by symptoms and physical exam findings, or by abnormal laboratory values. Another scenario is a palpable nodule, gland, or neck mass; the clinical question then is to localize the mass with respect to neck region landmarks, and/or the activity of the palpable finding. A third and growing scenario in all age groups is the incidentaloma, such as a questioned mass or an area of heterogeneous enhancement in the thyroid region, as may be noted on CTPA scans, carotid ultrasound, neck region MRI scans, or whole body radioisotope scans (usually PET). Problems that are more common in pediatrics include the workup of a palpable mass, dyphagia or airway compression, superior mediastinal mass or of rare but urgent cases of neonatal hypothyroidism. Overactivity can be attributed to hyperthyroidism, with many causes (and possible classifications), but which overlaps with thyrotoxicosis with respect to producing symptoms, which then must be differentiated by correlating other data with uptake/scan results. Scan uniformity is also a useful finding, bearing in mind several common variants. The clinical added value of the thyroid scan and uptake study is that many hyperthyroid entities are often treated initially with radioiodine, as opposed to thyrotoxicosis, which requires anti-inflammatory or supportive therapies. Other common causes of overactivity must be remembered such as medication effect; transient stages of thyroiditis (the many forms of thyroiditis, and some of the molecular biology that link them will be reviewed, including differential regulation of p63/p53 and CK 19, and commonality of oncocytic changes in Hashimoto9s/MALT tumors/B cell lymphoma/papillary CA). Palpable masses can be due to or co-exist with overactivity or thyrotoxicosis, and require localization and assessment of their activity with relation to normal thyroid. Intra-thyroidal nodules increase in incidence with age, and their initial management may include a thyroid scan. Incidentalomas in the thyroid region are found on many other imaging examinations, and the thyroid scan in these cases ideally is directly correlated with the original finding (and scheduled with the appropriate timing and technique, with respect to a finding on an IV-contrast enhanced CT or a radioisotope scan). Pediatric indications are rarer, especially the workup of neonatal hypothyroidism. Other uses are the evaluation of congenital or acquired neck region masses. Clinical images and histories to illustrate common scenarios will be included.
Longitudinal Bone Transport for Treatment of Primary Bone Tumors in Dogs: Technique Description and Outcome in 9 Dogs (2005)

BTO has an emerging role in limb salvage surgery for dogs with primary bone tumors. BTO provides excellent long-term outcomes in some dogs with primary bone tumors and will likely become increasingly more attractive as technique modifications allow the duration of the treatment to be shortened.
What Are the Proteolytic Enzymes of Honey and What They Do Tell Us? A Fingerprint Analysis by 2-D Zymography of Unifloral Honeys (2012)

Honey is a sweet and healthy food produced by honeybees (Apis mellifera L.) from flower nectars. Using bidimensional zymography, we have detected the, until now unrevealed, proteolytic activities present in row honey samples. The resulting zymograms were specific for each type of the four unifloral honey under study, and enzymes were identified as serine proteases by the use of specific inhibitors. Further, using bidimensional electrophoresis, we have shown that honey proteases are able to degrade the major Royal Jelly proteins and in particular MRPJ-1, the protein that promotes queen differentiation in honeybees. Our findings open new perspectives for the better understanding of honeybee development, social behaviour and role in honey production. The now discovered honey proteases may influence honey properties and quality, and bidimensional zymograms might be useful to distinguish between different honey types, establish their age and floral origin, and allow honey certification.
Prediction and Measurement of the Total Pressure Loss in an Engine Representative Diffuser System (1995)

An experimental and computational investigation of the flow in an engine representative diffuser system has been performed. Many parametric changes to the system were considered including inlet conditions, pre-diffuser geometry, cowl geometry and pre-diffuser strut position. The focus of this paper is an overview of the results from the twelve configurations that were both predicted and experimentally tested. It was shown that the CFD predictions contained a high degree of numerical error and that to reduce this to a low level would be currently impractical for a parametric study of this type. However, by carefully maintaining approximately the same degree of numerical error in the predictions, it was shown that a valid parametric study could be performed to the extent that the same conclusions about the parametric changes can be drawn equally from the predictions or measurements with one small exception. It was recognised that the level of agreement between the predicted and measured losses was to a degree fortuitous and that the k-ε turbulence model performs poorly for this type of flow.

Random Generator of Orthogonal Matrices in Finite Fields (2023)

We propose a superfast method for constructing orthogonal matrices $M\in\mathcal{O}(n,q)$ in finite fields $GF(q)$. It can be used to construct $n\times n$ orthogonal matrices in $Z_p$ with very high values of $n$ and $p$, and also orthogonal matrices with a certain circulant structure. Equally well one can construct paraunitary filter banks or wavelet matrices over finite fields. The construction mechanism is highly efficient, allowing for the complete screening and selection of an orthogonal matrix that meets specific constraints. For instance, one can generate a complete list of orthogonal matrices with given $n$ and $q=p^m$ provided that the order of $\mathcal{O}(n,q)$ is not too large. Although the method is based on randomness, isolated cases of failure can be identified well in advance of the basic procedure's start. The proposed procedures are based on the Janashia-Lagvilava method which was developed for an entirely different task, therefore, it may seem somewhat unexpected.
Novel optical single-mode asymmetric Y-branches for variable power splitting (1999)

Single-mode asymmetric Y-branches using microprisms are proposed. With a bend prism designed by the bend phase compensation rule (bend PCR) and a pair of Y-branch prisms designed by the Y-branch PCR, the phase front mismatch at the branching point is greatly eliminated, resulting in wide-angle low-loss 3-dB asymmetric Y-branches. Furthermore, control of power-splitting ratios is fulfilled through varying the lengths of prisms for a fixed branching angle and a fixed prism index. Finally, cascades of the proposed structures are studied. It is shown that the construction of a satisfactory 1/spl times/N tree power divider based on the cascaded structures is possible.
Multi-parametric functional imaging of cell cultures and tissues with a CMOS microelectrode array (2022)

Electrode-based impedance and electrochemical measurements can provide cell-biology information that is difficult to obtain using optical-microscopy techniques. Such electrical methods are non-invasive, label-free, and continuous, eliminating the need for fluorescence reporters and overcoming optical imaging's throughput/temporal resolution limitations. Nonetheless, electrode-based techniques have not been heavily employed because devices typically contain few electrodes per well, resulting in noisy aggregate readouts. Complementary metal-oxide-semiconductor (CMOS) microelectrode arrays (MEAs) have sometimes been used for electrophysiological measurements with thousands of electrodes per well at sub-cellular pitches, but only basic impedance mappings of cell attachment have been performed outside of electrophysiology. Here, we report on new field-based impedance mapping and electrochemical mapping/patterning techniques to expand CMOS-MEA cell-biology applications. The methods enable accurate measurement of cell attachment, growth/wound healing, cell-cell adhesion, metabolic state, and redox properties with single-cell spatial resolution (20 μm electrode pitch). These measurements allow the quantification of adhesion and metabolic differences of cells expressing oncogenes <i>versus</i> wild-type controls. The multi-parametric, cell-population statistics captured by the chip-scale integrated device opens up new avenues for fully electronic high-throughput live-cell assays for phenotypic screening and drug discovery applications.
Preparation, characterization, and evaluation of radiopaque hydrogel filaments for endovascular embolization (2008)

Radiopaque hydrogel filaments were prepared, characterized, and evaluated for potential use as implants for endovascular embolization of vascular defects. Three hydrogel formulations were prepared by free radical polymerization: (i) poly(ethylene glycol) diacrylate with 2,4,6-triiodophenyl penta-4-enoate (PEG-I), (ii) poly(ethylene glycol) diacrylamide with barium sulfate (PEG-B), and (iii) poly(propylene glycol) diacrylate with barium sulfate (PPG-B). The PEG-B and PPG-B hydrogels exhibited radiopacity comparable with clinically used platinum coils, whereas the PEG-I hydrogel did not. In the dry state, the average ultimate tensile strength and strain of the hydrogels ranged from 37 to 128 gf and 21% to 72%, respectively. The PEG-B hydrogel had significantly higher tensile strength compared with the PEG-I hydrogel. In the hydrated state, the average ultimate tensile strength and strain ranged from 5 to 15 gf and 7% to 30%, respectively. Statistically significant differences in tensile strength were not present when hydrated. Compared with poly(ethylene) after 4-week implantation into the subcutaneous space of rabbits, the PEG-I hydrogel elicited slightly more inflammation, whereas the PEG-B and PPG-B hydrogels elicited less inflammation. All three hydrogel formulations elicited less fibrous encapsulation than poly(ethylene). With further development, these materials have potential as embolization devices.
<title>Adaptive control of redundant multilink robot using fuzzy logic</title> (1993)

A new approach to fuzzy distance and restriction measures is used to obtain the appropriate orientations of the links for avoiding obstacles in the robot trajectories. This approach eliminates the classical task of solving highly coupled, nonlinear equations describing the ill- posed inverse problems of multilink robot motion at a much less demanding computational time. Such clear advantage of fuzzy logic based adaptive controller are illustrated by simulation results of guidance of a multilink robot in target positioning and trajectories tracking. The simulation results involve a three-link robot arm with capability of moving from one position to any desired position and tracking a defined trajectories accurately. A modified fuzzy rule based distance measure allows the robot to follow trajectories within hitting the obstacles in the path. The simulation results indicate the advantage of fuzzy logic based adaptive controllers in multiple criteria decision-making tasks.
