Development of Fused Deposition Modeling of Multiple Materials (FD3M) Through Dynamic Coaxial Extrusion (2023)

Multimaterial additive manufacturing is expanding the design space realizable with 3D printing, yet is largely constrained to sequential deposition of each individual material. The ability to coextrude two materials and change the ratio of materials while printing would enable custom-tailored polymer composites. Here, the evolution of a dynamic material coextrusion process for additive manufacturing capable of printing any ratio between and including two neat input materials is described across 3 hot-end generations and 14 implemented design iterations. The designs evolved with increased understanding of manufacturing constraints associated with the additive manufacturing of metal components with internal flow bore diameters on the order of 2 mm and typical bore length around 50 mm. The second generation overcame this issue by partitioning the design into two pieces to locate the flow channel geometry at the interface between the components so that the details could be easily printed on the components' external surfaces. The third concept generation then focused on minimizing flow channel volume to reduce the average length when transitioning between materials by 92%. The third-generation design was also used to investigate the improvements in dimensional stability during annealing of acrylonitrile butadiene styrene (ABS) made possible by coextruding ABS with a polycarbonate (PC) core. The standard deviation of part shrinkage after annealing was 7.08% for the neat ABS but reduced to 0.24% for the coextruded ABS/PC components.

Impalpable prostate cancer: clinicopathological features (1996)

Cancers detected incidentally at TURP tend to be small T1a tumours, possibly suitable for conservative management. T1b cancers are likely to be detected by PSA level and treated radically. T1c and impalpable T2 cancers are morphologically unlike T1b disease and justifiably belong in separate stages in the current UICC staging system.
Analyse par spectroscopie d'émission des molécules carbonées impliquées dans la croissance de poudres par plasma (2014)

Les plasmas sont des gaz ionises qui se rencontrent dans l’industrie mais qui sont egalement tres presents dans la nature. En effet, constituants principaux des etoiles, ils se rencontrent egalement dans les cometes et certaines atmospheres planetaires. Sur Terre, on les trouve notamment dans les eclairs ou les aurores boreales. Ces plasmas contiennent souvent des particules solides en suspension et on parle alors de plasmas poudreux (ou poussiereux, en anglais dusty plasmas ou complex plasmas).
Au laboratoire GREMI, les poudres sont formees au sein du plasma par l’intermediaire de precurseurs gazeux. Dans ce dernier cas, des gaz reactifs a base de carbone (methane, acetylene) sont souvent utilises. Des liquides (alcools legers) sont egalement vaporises pour certaines applications liees a la formation de suies issues de biocarburants. Generalement, les poudres se forment et croissent via une succession complexe de reactions chimiques et physiques par des processus de nucleation, coagulation, agglomeration et adsorption. 
Dans ce travail, les precurseurs gazeux ne sont pas injectes sous forme de gaz mais sont issus de la pulverisation d'un materiau polymere expose a un plasma d'Ar (ou Kr). Les ions viennent arracher des molecules carbonees qui se retrouvent dans le plasma et vont initier la nucleation et la croissance des poudres. Une analyse par spectroscopie d'emission optique est menee pour suivre l'evolution spatiale et temporelle des molecules C2, CN, CH, CO, Ar (ou Kr). Les raies des especes carbonees augmentent au cours du temps pendant le processus de pulverisation puis diminuent. Cette diminution est en partie liee a leur disparition du fait de leur participation au processus de croissance des poudres.
Quantum mechanical linear filtering of vector signal processes (1977)

The problem of estimating a member of a discrete-time vector process from past and present quantum mechanical measurements is considered; specifically, the minimum-variance linear estimator based on optimal present measurements is studied. Necessary and sufficient conditions that characterize the optimal processing matrix coefficients and the optimal measurements are discussed and interpreted. The optimal linear filter is compared to the optimal quantum estimator without postprocessing of past data. When the signal sequence is pairwise Gaussian and the optimal quantum measurement without postproccssing has the properties that it is linear in a specific sense and that its outcome and the corresponding element of the signal sequence are jointly Gaussian, then the optimal linear filter separates. That is, the optimal measurement can be taken to be the same as thc optimal measurement without regard to past data, and the past and present data are processed classically. Thc results are illustrated by considering the filtering of the in-phase and quadrature amplitudes of a laser field received in a single-mode cavity along with thermal noise. In this case, when the random signal sequence satisfies a linear recursion, the estimate can be computed recursively in a very efficient manner.
Disordering of ZnSe/ZnS strained-layer superlattices by Si ion implantation (1989)

Disordering of ZnSe/ZnS strained-layer superlattices(SLSs) induced by Si ion implantation and subsequent low-temperature thermal annealing was confirmed. Si ions were implanted (100 keV, 1×1016 ions/cm2 ) into SLSs (140 Å ZnSe-140 Å ZnS, ten periods). By secondary-ion mass spectrometry analyses, periodic profiles of Se and S were clearly observed just after the ion implantation; however, they disappeared after subsequent thermal annealing (450 °C, 3 h). Photoluminescence measurements showed the peak of ZnSx Se1−x alloyed crystal after thermal annealing. The disordering is mainly induced by the diffusion of defects generated by the ion implantation at the early stage of low-temperature thermal annealing. This low temperature and planar process will be very useful to the fabrication of II-VI compound semiconductor optical and electrical devices.

Recurrent Neural Network Soft Demapping for Mitigation of Fiber Nonlinearities and ISI (2021)

Optical transmission systems suffer from linear and nonlinear impairments induced by components and fibers. As countermeasures, neural network soft-demappers are proposed and benchmarked against combinations of digital back-propagation, Volterra equalizers, noise whitening and soft-output Viterbi-algorithms.
Asymptotically optimal transmit strategies for the multiple antenna interference channel (2008)

We consider the interference channel with multiple antennas at the transmitter. We prove that at high signal-to-noise ratio (SNR), the zero-forcing transmit scheme is optimal in the sum-rate sense. Furthermore we prove that at low SNR, maximum-ratio transmission is optimal in the sum-rate sense. We also provide a discussion of the connection to classical results on spectral efficiency in the wideband regime. Finally, we propose a non-convex optimization approach based on monotonic optimization to solve the sum rate maximization problem.
Supplementary Figure S1. HPV capture methodology from Targeted, Deep Sequencing Reveals Full Methylation Profiles of Multiple HPV Types and Potential Biomarkers for Cervical Cancer Progression (2023)

&lt;p&gt;(1) Genomic DNA (gDNA) was sheared into ~300 bp fragments that were end-repaired, adenylated, and ligated to Illumina TruSeq adapters. (2) The prepared library was hybridized with Agilent's Custom HPV Capture Library and IDT's xGen Lockdown Probes. (3) Streptavidin-coated beads were used to target and separate the 5'-biotinylated end of the bound hybrids. Unbound gDNA was washed away, and captured hybrids were eluted. (4) For methylation analysis, samples were treated with BS, which converts unmethylated cytosines to uracil. (5) Captured hybrids were PCR-amplified with primers specific to the Illumnia TruSeq Adapters. Finally, libraries were indexed to provide each with a unique 6 base pair code. Pooled libraries were sequenced using the Illumina HiSeq 2000 workflow.&lt;/p&gt;
Gene Expression Signature of Host Immune Response Is Predictive of Follicular Lymphoma Patient Survival in Independent Cohorts, and Correlates with Transformation to Diffuse Large B-Cell Lymphoma. (2009)

Abstract Abstract 2951 Poster Board II-927 Background: Expression signatures of infiltrating immune cells [1] have been shown to predict survival in follicular lymphoma (FL), but have not been cross-validated in independent patient cohorts [2,3]. These signatures may relate biologically to the frequency of infiltrating including T-cells and macrophages, or to specific transcription programs within tumor cells and/or the tumor microenvironment. We sought to evaluate the validity of this model in an independent cohort of patients with FL, assessing its relationship to outcomes including histological transformation and death. Methods: The immune response (IR) predictor score proposed by Dave et al. [1] was applied to gene expression data from an independent cohort of 88 FL patients [4] with known survival outcomes and history of transformation to diffuse large B-cell lymphoma (DLBCL). Genes (n=66) corresponding to IR1 and IR2 signatures were mapped from Affymetrix microarrays [1] to a custom cDNA array [4] via Entrez Gene ID, and the composite IR score was calculated per the scheme proposed by Dave et al. Results: The IR score was predictive of patient outcome in the 88 patient test set as a continuous variable (p=0.001, HR=2.01, 95% CI 0.50-1.30). Partitioning of patients into high and low risk groups based on the median IR score across the cohort robustly separated survival curves (Figure A). The IR score was significantly higher in FL patients known to undergo transformation to DLBCL (Figure B: mean IR score of -0.6 in non-transforming FL vs. -0.2 in transforming FL; p∼10-11, t-test). Conclusions: The IR score of Dave et al. was highly significant as a predictor of survival in the independent patient cohort [4]. Moreover, the score was significantly associated with propensity of FL to transform to DLBCL. To our knowledge, immune cell infiltration has not previously been implicated in transformation. 1.

Charge–Discharge with Rocking-Chair-Type Li+ Migration Characteristics in a Zwitterionic Radical Copolymer Composed of TEMPO and Trifluoromethanesulfonylimide with Carbonate Electrolytes for a High-Rate Li-Ion Battery (2017)

Redox-active copolymer containing organic robust radical, 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO), and charge neutralizing anion, trifluoromethanesulfonylimide (TFSI–) was synthesized as a cathode material of a Li-ion battery. The copolymer, poly(2,2,6,6-tetramethylpiperidin-1-oxy-4-yl methacrylate-co-styrenesulfonyl(trifluoromethanesulfonyl)imide) (P(TMA-co-TFSI)), was designed to give rise to the Li+ migration during its charge–discharge process, based on the self-charge compensation of TEMPO with TFSI– bound to the polymer chain in a widely used electrolyte system for Li-ion battery, organic carbonate mixtures. Copolymerization was performed to achieve efficient self-charge compensation with uniformly distributed TFSI– units. The P(TMA-co-TFSI) layer electrode exhibited reversible redox reaction at 0.73 V vs Ag/AgCl. Electrochemical measurements combined with quartz crystal microbalance analysis evidenced that the redox reaction involved the Li+ migration in binary system of ethylene carbonate and diethyl carbonate. A test cell fabricated with the P(TMA-co-TFSI) cathode exhibited high discharging voltage of 3.7 V and high-rate charge–discharge capability at 30 C (i.e., full charging in 2 min).
Metal-oxide thin-film transistors patterned by printing (2013)

We demonstrate thin-film transistors with the fabrication advantages associated with printed electronics and the device performance associated with inorganic materials that are typically patterned via photolithography. In this process a polymeric material is printed to selectively inhibit the deposition of the electrically active material, which is globally applied via spatial atomic layer deposition. We identify water-soluble inhibitors that make attractive choices for printable ink formulations and explore the interactions of two examples of polymeric inhibitors with the process space. Using this knowledge we demonstrate zinc oxide thin film transistors, patterned entirely by inkjet-printed polyvinyl pyrrolidone.

Connectivity of Features in Microlens Array Reduction Photolithography:  Generation of Various Patterns with a Single Photomask (2002)

Microlens array photolithography (MAP) is a technique in which arrays of microlenses positioned close to photoresist reduce cm-sized figures on photomasks and form mum-scale images in the photoresist. This work demonstrates that MAP, using a single photomask, can generate patterns having different symmetries and periodicities from that of the lens array. This capability of MAP depends on (i) the connectivity between the images produced by individual microlenses and (ii) the orientation of the photomask relative to the lens array prior to exposure. By changing this orientation, MAP, using a single mask and a single array of microlenses, could be used to generate patterns that (i) are separated from each other, (ii) overlap with each other, (iii) are 2D chiral, and thus different from both the lens array and the mask in symmetry, (iv) have a symmetry reduced from that of the lens array, or (v) have a smaller unit cell and smaller pitch than that of the lens array.
2-Butyl-11-phenyl-5,10-dihydro-1H-benzo[e]imidazo[1,5-a][1,4]diazepine-1,3(2H)-dione (2010)

The title compound, C(21)H(21)N(3)O(2), was obtained following a five-step synthetic procedure yielding weakly diffracting rod and needle-shaped crystals which crystallized concomitantly. Structural analysis of a rod-shaped crystal showed that the central seven-membered heterocyclic ring adopts a conformation that is perhaps best described as a distorted boat, with the H-bearing (CH(2) and NH) atoms lying well out of the least-squares mean plane fitted through the other five atoms in the ring (r.m.s. deviation 0.075 Å). In the crystal, the compound packs as a twisted chain, which propagates along the b axis by means of an R(1) (2)(6) motif formed by one of the carbonyl O atoms acting as a bifurcated acceptor in an N-H⋯O and C-H⋯O inter-action. No diffraction was observed from the needle-shaped crystals.
The role of carbon nanotubes (CNTs) and carbon particles in green enhanced oil recovery (GEOR) for Arabian crude oil in sandstone core (2020)

Green enhanced oil recovery (GEOR) is a chemical enhanced oil recovery (EOR) involving the injection of specific green chemicals (surfactants/alcohols/polymers) that effectively displace oil because of their phase-behaviour properties, which decrease the IFT between the displacing liquid and the oil. Carbon nanoparticles application in EOR has sparked interest in the last few years due to its unique characteristics. Carbon nanotubes (CNTs) are one of the common carbon nanomaterials with EOR potential, but they are not used with green surfactant to improve oil recovery. In addition, the recently developed Date Leaf Carbon Particle (DLCP) method has not been applied to GEOR and requires further study. The role of carbon particles in GEOR is not well understood and requires further investigation. This study was conducted to examine the effectiveness of DLCP and CNT in green surfactant alkyl polyglucoside (APG) for recovering residual oil within rock pores. The study consisted of a set of laboratory experiments. Two formulations of DLCP, CNT and green surfactant mixtures were selected for core-flood experiments based on interfacial tension measurements to examine their potential for EOR. In the first formulation, 0.08% DLCP was mixed with 0.5% APG and produced 45% of tertiary oil and 89% of oil initially in place (OIIP). This formulation produced a significant quantity of incremental oil after water flooding. Lastly, 0.5% APG was blended with 0.08% CNT; this produced about 27% tertiary oil and 77% OIIP.

高圧凝固鋳造により製造されたSic繊維強化Al-Cu合金複合材の引張強さにおよぼすCu添加量の影響を調べた. その結果, 1%Cu添加材が最大の強さとなることを示し, その原因について解明した. さらに複合材の高温加熱保持後の引張強さを調査し, 473Kで最大の強さを示すこと, 573Kを越えると保持温度および時間の増加と共に強さは低下することを明白にした. この現象を複合材の内部応力と繊維-母地間の反応の見地から考察した.
Development of a novel confocal microscope for functional recording of fast neuronal activity (2002)

Currently available recording methods limit the study of fast neuronal signaling by forcing a tradeoff between spatial and temporal resolution. Fortunately, advanced optical imaging techniques can be used to overcome this limitation. Specifically, we are developing confocal microscopy schemes that allow multisite recordings of neuron function in live brain tissue with high spatial and temporal resolution. The first scheme that is currently being investigated involves the use of a digital micromirror device (DMD) to implement the light paths necessary for high-speed confocal imaging: addressable point illumination and spatial filtering via addressable point detection. The second scheme involves the use of acousto-optic deflectors (AODs) in the illumination path to increase the excitation intensity, along with the DMD or an addressable CMOS imager as the spatial filter in the detection path. Calculations of the signal-to-noise ratios and operating parameters of the three devices indicate that we will be able to study both calcium concentration and fast membrane potential changes at several sites within the dendritic tree of a neuron.
Salivary biomarkers of bacterial burden, inflammatory response, and tissue destruction in periodontitis (2014)

Salivary concentrations of MMP-8, IL-1β, and P. gingivalis are associated with various clinical and radiographic measures of periodontitis. The CRS index, combining the three salivary biomarkers, is associated with periodontitis more strongly than any of the markers alone regardless of the coronary artery disease status of the patients.
GASTRO RETENTIVE DRUG DELIVERY SYSTEMS: A REVIEW (2020)

The stomach has four main regions: the cardia, fundus, body and pyloric part. The cardiac surrounds the superior opening of the stomach. The rounded portion superior to and to the left of the cardia is the fundus. Inferior to the fundus is the large central portion of the stomach, the body. The pyloric part is divisible into three regions. The first region, the pyloric antrum, connects to the body of the stomach.
Accrual and retention of diverse patients in psychosocial cancer clinical trials (2022)

These results corroborate evidence of no significant differences in CCT interest across minority groups, with older adults less likely to fulfill eligibility criteria. While absolute Hispanic enrollment was modest, Hispanic patients were more likely to enroll relative to non-Hispanic patients. Additional sociodemographic trends were noted in decline motivation and geographical prediction of attrition. Further investigation is necessary to better understand inequities, barriers, and best recruitment practices for representative CCTs.
