Augmented manual fabrication methods for 2d tool positioning and 3d sculpting (2013)

Augmented manual fabrication involves using digital technology to assist a user engaged in a manual fabrication task. Methods in this space aim to combine the abilities of a human operator, such as motion planning and large-range mechanical manipulation, with technological capabilities that compensate for the operator's areas of weakness, such as precise 3D sensing, manipulation of complex shape data, and millimeter-scale actuation.
This thesis presents two new augmented manual fabrication methods. The first is a method for helping a sculptor create an object that precisely matches the shape of a digital 3D model. In this approach, a projector-camera pair is used to scan a sculpture in progress, and the resulting scan data is compared to the target 3D model. The system then computes the changes necessary to bring the physical sculpture closer to the target 3D shape, and projects guidance directly onto the sculpture that indicates where and how the sculpture should be changed, such as by adding or removing material. We describe multiple types of guidance that can be used to direct the sculptor, as well as several related applications of this technique.
The second method described in this thesis is a means of precisely positioning a handheld tool on a sheet of material using a hybrid digital-manual approach. An operator is responsible for manually moving a frame containing the tool to the approximate neighborhood of the desired position. The device then detects the frame's position and uses digitally-controlled actuators to move the tool within the frame to the exact target position. By doing this in a real time feedback loop, a tool can be smoothly moved along a digitally-specified 2D path, allowing many types of digital fabrication over an unlimited range using an inexpensive handheld tool.

Reaction of the diisopropylaminochlorophosphenium cation with crotonaldehyde dimethylhydrazone and acetone azine (1990)

Abstract The phosphenium ion [( i ‐Pr 2 N)CIP] + ( 1 ) reacts with crotonaldehyde dimethylhydrazone ( 2 ) to afford a product with a C 3 NP ring system ( 4 ) . The reaction of 1 with acetone azine ( 3 ) results in a novel tricyclic compound ( 6 ) which features a C 2 N 2 P 2 and two C 2 N 2 P rings. The structures of 4 and 6 were established by X‐ray crystallography. Compound 4 , C 12 H 26 AlCl 3 N 3 OP, crystallizes in the monoclinic space group P 2 1 / n with Z = 4, a = 15.400(6), b = 14.442(4), c = 9.206(3) Å, and β = 93.33(3)°. Compound 6 , C 12 H 22 Al 2 Cl 6 N 4 O 2 P 2 , crystallizes in the triclinic group P 1 with Z = 1, a = 8.556(1), b = 9.782(1), c = 8.119(1) Å, α = 94.48(1), β = 104.97(1), and γ = 78.35(1)°.
Ulcerative colitis and sarcoidosis. (2001)

A 38-year-old woman with ulcerative colitis subsequently developed sarcoidosis. After ten years of recurrent episodes of colitis, she had presented with respiratory symptoms. The diagnosis of sarcoidosis was confirmed by mediastinal lymph node biopsy. Her respiratory symptoms gradually resolved without any specific treatment. Within the remission period of sarcoidosis, she underwent uneventful subtotal colectomy due to refractory colitis. Alterations in immune function and genetic susceptibility have been suggested to be present in both ulcerative colitis and sarcoidosis. However, the occurrence of both in the same patient has been rare. This is only the nineteenth case reported in the literature.
Towards strain-independent anti-influenza peptides: a SAXS- and modeling-based study (2013)

Using small angle X-ray scattering (SAXS) data, we reconstructed the scattering shape of the Hemagglutinin (HA) trimer protein from five different influenza strains. Comparison with the known crystal structures-based information aided in identifying volumes pertaining to the glycosylation in the HA trimers. By merging sequence information on HA proteins from pathogenic strains of influenza, we identified a novel druggable pocket composed of residues which remained conserved during evolution, lack propensity to be glycosylated, and play important role in maintaining interchain contacts in the pH-sensitive head group. To test our hypothesis that molecules reactive to this site may retard pH-induced opening of HA trimer in strain-independent manner, we performed in vitro screening of peptides representing interacting epitopes for their ability to retard pH-induced opening of HA trimers. Results brought forth that some of the 20 peptides tested can retard low pH-induced opening/association of HA proteins across different subtypes, thus propagating notion that the drug site and peptides identified here may pave way towards strain-independent anti-influenza molecules.
A Sales Execution Strategy Guide for Technology Startups (2011)

IntroductionEntrepreneurs are exposed to a wide range of assistance and mentorship. Much of this help is focused on solution development and product-level commercialization. Both are important and are rightly fundamental to future investment decisions on the part of angels and venture capital companies. These two areas do not, however, offer a complete picture of sustainable
Methadone‐associated QT interval prolongation in patients undergoing maintenance therapy in an urban opioid treatment program (2020)

Approximately 15% of patients taking maintenance methadone therapy developed QT interval prolongation. Both serum (S)- and (R)-methadone concentrations, but not (S)- or (R)-EDDP, contribute to methadone-associated QT prolongation.
Phase transition in magic with random quantum circuits (2023)

Magic is a property of quantum states that enables universal fault-tolerant quantum computing using simple sets of gate operations. Understanding the mechanisms by which magic is created or destroyed is, therefore, a crucial step towards efficient and practical fault-tolerant computation. We observe that a random stabilizer code subject to coherent errors exhibits a phase transition in magic, which we characterize through analytic, numeric and experimental probes. Below a critical error rate, stabilizer syndrome measurements remove the accumulated magic in the circuit, effectively protecting against coherent errors; above the critical error rate syndrome measurements concentrate magic. A better understanding of such rich behavior in the resource theory of magic could shed more light on origins of quantum speedup and pave pathways for more efficient magic state generation.
Characteristics of Patients for Whom Benznidazole Was Released Through the CDC-Sponsored Investigational New Drug Program for Treatment of Chagas Disease — United States, 2011–2018 (2018)

Chagas disease (also known as American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi (1,2). Vectorborne transmission via skin or mucosal contact with the feces of infected triatomine bugs mainly occurs in rural areas of Latin America but has been reported in the southern United States (3). The parasite also is transmissible congenitally and via blood transfusion, organ transplantation, and accidental laboratory exposures. The two drugs used for treating Chagas disease are benznidazole and nifurtimox (1,2), which have been used in Latin America since the 1970s and 1960s, respectively. In the absence of commercially available drugs approved by the Food and Drug Administration (FDA), benznidazole and nifurtimox have been available exclusively through CDC, under Investigational New Drug (IND) treatment protocols. On August 29, 2017, FDA approved a benznidazole product (Chemo Research, SL, in care of Exeltis*) for treatment of Chagas disease (4), which became commercially available on May 14, 2018. Therefore, effective May 14, 2018, benznidazole is no longer available through the CDC-sponsored IND program. This report summarizes selected characteristics of patients for whom CDC released benznidazole through that program from October 2011, when the IND went into effect, until mid-May 2018. The majority of the 365 patients included in intention-to-treat analyses were chronically infected adults who were born and became infected in Latin America. Physician requests for benznidazole should now be directed to the drug company Exeltis.<sup>†</sup> The CDC-sponsored IND for nifurtimox remains in effect to provide an alternative therapeutic option to benznidazole when clinically appropriate. CDC will continue to provide reference diagnostic testing for T. cruzi infection and teleconsultative services regarding Chagas disease.
High resolution optics combined with high spatial reproducibility in flow (1981)

Accurate sizing in flow using optical methods generally requires high resolution optics and specially designed flow systems. Flow systems developed by this group have following features: (a) double sheath configuration for optical index match, (b) no curved optical surface in the sensing area, (c) gradual hydrodynamic focusing over a long distance to minimize mechanical shearing, (d) precision spatial positioning of cells by reducing suspension fluid diameter to a cell diameter or less, (e) total thickness between outer surfaces of the flow chamber at the viewing area of 1.5 mm or less. Cells intersect a laser light beam focussed go circular as well as elliptical cross-sections or 1 micron or less in diameter. Cellular extinction is monitored during transit through the beam. Cell length is derived from the time for flight measurement and corrected for absolute values by continuous velocity reference using a second laser beam intersecting the cell stream at a predetermined distance. This second spot may be circular or elliptical, of a different polarization and/or frequency. Simultaneous fluorescence intensity and diameter measurements were performed on test particles using different optical geometries. The influence of the particle structure on fluorescence measurements is demonstrated where high resolution sizing is required at the same time.
Demonstration of 122% wall plug efficiency in uncooled single mode external-cavity tunable Si/III-V hybrid laser (2015)

A Si/III-V hybrid laser has been a highly sought after device for energy-efficient and cost-effective high-speed silicon photonics communication. We present a high wall-plug efficiency external-cavity hybrid laser created by integrating an independently optimized SOI ring reflector and a III-V gain chip. In our demonstration, the uncooled integrated laser achieved a waveguide-coupled wall-plug efficiency of 12.2% at room temperature with an optical output power of ~10 mW. The laser operated single-mode near 1550 nm with a linewidth of 0.22 pm. This is a tunable light source with 8 nm wavelength tuning range. A proof-of-concept laser wavelength stabilization technique has also been demonstrated. Using a simple feedback loop, we achieved mode-hop-free operation in a packaged external-cavity hybrid laser as bias current was varied by 60mA.

A sine-LO square-law harmonic-rejection mixer—theory, implementation, and application (2014)

A square-law harmonic-rejection mixer (SL-HRM) driven by a sine local oscillator (LO) is proposed for wideband and tunable rejection of all LO harmonics. The key performances including the gain, noise figure (NF), input-referred third-order intercept point (IIP3), and harmonic rejection ratio (HRR) with respect to the amplitude and purity of the sine-LO are analyzed. In the circuit level, the SL-HRM incorporates a voltage-boosted technique to surmount the gain and NF penalties of square-law mixing, while guaranteeing the device reliability via introducing a supply startup circuit and a node-voltage protection circuit. The entailed high-purity sine-LO is achieved via a digital-intensive square-to-sine LO generator plus a passive- RC low-pass filter. Fabricated in 65-nm CMOS, the VHF-/UHF-band SL-HRM has a tunable gain of 1-13 dB, associated with an NF of 27-15 dB, under an LO amplitude of 50-200 mV pp. The IIP3 is stable within from +6.5 to +7.6 dBm, as expected. The tunable HRR3 and HRR5 are 13-40 dB and 17-45 dB, respectively. The mixer core consumes 7.5 mW at 2.5 V, while the LO generator draws 3-6 mW at 1.2 V. The total active area is just 0.042 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
On-line monitoring of high-temperature corrosion from superheater materials: KOMET 650 - Sub-project 2.2 (2003)

Within the scope of the sub-project 2.2 - On-line Corrosion Monitoring - of the KOMET 650-Project, LUAT of the Essen University carried out extensive investigations on the high-temperature corrosion behaviour of common and high-alloyed superheater materials for fossil-fired boilers. Impedance spectroscopy and electrochemical noise method have been examined with respect to their capability and usability for on-line corrosion monitoring at high temperature conditions. In co-operation with the Central Electronics Laboratory (ZEL) of the Juelich Research Centre an electronic device for the application in power stations has been developed. (orig.)
Preparation of Cytocompatible ITO Neuroelectrodes with Enhanced Electrochemical Characteristics Using a Facile Anodic Oxidation Process (2017)

Abstract Physicochemical modification of implantable electrode systems is recognized as a viable strategy to enhance tissue/electrode integration and electrode performance in situ. In this work, a bench‐top electrochemical process to formulate anodized indium tin oxide (ITO) films with altered roughness, conducting profiles, and thickness is explored. In addition, the influence of these anodized films on neural cell adhesion, proliferation, and function indicates that anodized ITO film cytocompatibility can be altered by varying the anodization current density. Furthermore, ITO‐anodized films formed with a current density of 0.4 mA cm −2 show important primary neural cell survival, modulation of glial scar formation, and promotion of neural network activity.
Mediolateral femoral component position in TKA significantly alters patella shift and femoral roll-back (2017)

In day-by-day use, ML position should be chosen with care since there is a significant influence on patella shift and femoral roll-back. Retropatellar pressure is not significantly altered, so there is no clear evidence of an impact on anterior knee pain.
Genetische modificatie tomaat en chrysant (2010)

Gedurende 1999 en 2000 zijn in dit project tomaten en chrysanten getransformeerd met genen waarvan kon worden aangenomen dat ze van invloed zijn op de energiehuishouding. Deze aanname berust op effecten die door deze genen in andere planten zijn opgewekt bijv. een andere gewasopbouw en lichtonderschepping. De werkelijke effecten op de energiebehoefte van de genetisch gemodificeerde tomaten en chrysanten worden in het project "Teeltanalyse transgene planten tomaat en crysant" onderzocht. In het vervolg traject "Genetische modificatie van tomaat en chrysant, analyse op plantniveau" zijn de effecten van verhoogde niveaus van phyA, phyB1 en phyB2 op de schaduw-vermijdings-reactie (SAR) onderzocht, door fytochroomgenen in tomaat tot overexpressie te brengen
Visual Comparison of Datasets Using Mixture Decompositions (2004)

This article describes how a mixture of two densities, f0 and f1, may be decomposed into a different mixture consisting of three densities. These new densities, f+, f-, and f=, summarize differences between f0 and f1: f+ is high in areas of excess of f1 compared to f0; f- represents deficiency of f1 compared to f0 in the same way; f= represents commonality between f1 and f0. The supports of f+ and f- are disjoint. This decomposition of the mixture of f0 and f1 is similar to the set-theoretic decomposition of the union of two sets A and B into the disjoint sets AB, BA, and A ∩ B. Sample points from f0 and f1can be assigned to one of these three densities, allowing the differences between f0 and f1 to be visualized in a single plot, a visual hypothesis test of whether f0 is equal to f1. We describe two similar such decompositions and contrast their behavior under the null hypothesis f0 = f1, giving some insight into how such plots may be interpreted.We present two examples of uses of these methods: visualization of departures from independence, and of a two-class classification problem. Other potential applications are discussed.
Discrete-Time Adaptive Control for Systems With Input Time-Delay and Non-Sector Bounded Nonlinear Functions (2018)

This paper presents a discrete-time adaptive control approach for nonlinear systems with input delay. The nonlinearity is assumed to be non-sector bounded, resulting in the key technical lemma being inapplicable. The main aim of this paper is to present a general implementation inspired from Kanellakopoulos and Fu, <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">et al.</i> for italic uncertain scalar and multivariable input delay systems with uncertain parameters as well as uncertain input gain. While it has been shown by Kanellakopoulos and Fu, <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">et al</i> . that it is possible to design adaptive control laws that compensate for the growth of the nonlinearity for single parameter scalar systems, a rigorous analysis of multiple parameter systems is not shown. In this paper, it is shown that an adaptive controller design that compensates for the growth of the nonlinearity is possible for both multiple parameter scalar and multivariable systems with input delay. Rigorous stability proofs and simulations are presented to verify the validity of the approach.

Synthetic F0 can effectively convey speaker ID in delexicalized speech (2012)

We investigate the extent to which F0 can convey speaker ID in the absence of spectral, segmental, and durational information. We propose two methods of F0 synthesis based on the Linear Alignment Model (LAM) [2]: one parametric, the other corpusbased. Through a perceptual experiment, we show that F0 alone is able to convey information about speaker ID. We find that F0 synthesized with either LAM-based method conveys speaker ID almost as effectively as natural F0.
