Integration of PDMS microfilters and micromixers bonded onto APTES-functionalized polymeric films for size sorting and mixing of microparticles (2014)

In this work, 3-(aminopropyl)triethoxysilane (APTES) was applied to functionalize flexible non-porous polymer substrates of polyimide (PI), polyethylene naphthalate (PEN), and polyethylene terephthalate (PET) that were bonded onto oxygen activated poly(dimethylsiloxane) (PDMS) microfiltering and micromixer devices. The feasibility of filtering using pillar filters was observable with poly(lactic-co-glycolic acid) (PLGA) microparticles (MPS), followed by the mixing capabilities of the micromixer with MPS in poly(vinyl alcohol) (MPS-PVA). A mixing performance of 17.6 % at 5 mm was observed. Finally, the PDMS microfilter was connected to the PDMS micromixer for filtration of MPS with dimensions of <; 11 μm. Those particles which were smaller then entered into the mixer and a mixing performance of 62.5% at 3 mm was observed. To our knowledge, we have exhibited the first complex PDMS microfilter and micromixer that has been integrated for MPS size sorting and mixing based on PI, PEN, and PET. These results demonstrate the development of microfluidic components using APTES for PDMS-thermoplastic film bonding that is based on a simple connection for lab-on-a-chip (LoC) devices where real samples require filtering and mixing of particles or suspensions.
Lessons Learned on Cervical Total Disc Replacement after 7 years Follow-up (2011)

Cervical spine fusion was well adopted since the 1950s to stabilize, treat degenerative changes and reduce deformity. Various studies demonstrate that single-level ACDF do alter spinal kinematics and compromise global spinal motion. Along with critical clinical and scientific overview, arthroplasty technology was developed to maintain movement and reduce adjacent segment stress and degeneration. Here we point out to the success and the complications after our 7 years experience with PCM total disc replacement.

RSPO3 is a prognostic biomarker and mediator of invasiveness in prostate cancer (2019)

RSPO3 levels are lower in prostate cancer than normal prostate, with a tendency for further loss in metastatic disease. Patients with lower RSPO3 expression have lower rates of biochemical relapse-free survival. SiRNA-mediated loss of RSPO3 results in no change to clonogenic survival and a lower proliferative rate, but increased invasiveness in vitro with induction of epithelial-mesenchymal transition (EMT) markers. Consistent with these results, lower RSPO3 expression translates to greater metastatic capacity in the CAM assay. Together, our preclinical findings identify a role of RSPO3 downregulation in prostate cancer invasiveness, and provide a potential explanation for how RSPO3 functions as a positive prognostic marker in prostate cancer.
A panchromatic anthracene-fused porphyrin sensitizer for dye-sensitized solar cells (2012)

The development of ruthenium-free sensitizers which absorb light over a broad range of the solar spectrum is important for improving the power conversion efficiency of dye-sensitized solar cells. Here we study three chemically tailored porphyrin-based dyes. We show that by fusing the porphyrin core to an anthracene unit, we can extend the conjugation length and lower the optical gap, shifting the absorption spectrum into the near-infrared (NIR). All three dyes were tested in dye-sensitized solar cells, using both titanium dioxide and tin dioxide as the electron-transport material. Solar cells incorporating the anthracene-fused porphyrin dye exhibit photocurrent collection at wavelengths up to about 1100 nm, which is the longest reported for a porphyrin-based system. Despite extending the photon absorption bandwidth, device efficiency is found to be low, which is a common property of cells based on porphyrin dyes with NIR absorption. We show that in the present case the efficiency is reduced by inefficient electron injection into the oxide, as opposed to dye regeneration, and highlight some important design considerations for panchromatic sensitizers.
Discriminative Autoencoder (2018)

Classification using cross-datasets (where a classifier trained using annotated image set A is used to test similar images of set B due to lack of training images in B) is important for many classification problems especially in biomedical imaging. We propose a discriminative autoencoder, useful for addressing the challenge of classification using cross-datasets. Our autoencoder learns an encoder and decoder such that the distances between the representations of the same class is minimized whereas the distances between the representations of different classes are maximized. We derive a fast algorithm to solve the aforementioned problem using the Augmented Lagrangian Alternating Directions Method of Multipliers (ADMM) approach. ADMM is a faster alternative to back-propagation which is used in standard autoencoders. The proposed method outperforms state-of-the-art representation learning tools in terms of classification results in breast cancer related histopathological image set MITOS and AMIDA and some of the benchmark image datasets.
The Human Vitamin D Receptor Gene (VDR) Is Localized to Region 12cen-q12 by Fluorescent In Situ Hybridization and Radiation Hybrid Mapping: Genetic and Physical VDR Map (1999)

The vitamin D receptor (VDR) is a member of the steroid hormone receptor superfamily of ligand-activated transcription factors. The VDR gene was previously mapped to human chromosome 12q13-12q14, but its precise physical and genetic localization are unknown. The present study reports the mapping of the human VDR gene by radiation hybrid (RH) analysis, the isolation of a bacterial artificial chromosome (BAC) containing this gene, and physical mapping of the VDR gene by fluorescent in situ hybridization (FISH). RH analysis placed the VDR gene locus at chromosome 12cen-q12, flanked by Stanford Human Genome Center (SHGC) 30216 and SHGC 9798 (D12S1892) markers. FISH analysis of a BAC containing the VDR gene confirmed its centromeric location. Thus, we have identified a BAC and genetic markers which can be used in the genetic analysis of the VDR gene and investigation of its involvement in osteoporosis and related disorders. We conclude that the VDR gene is centromeric to its previously reported locus on chromosome 12.
A meeting detector and its applications (2004)

In this paper we present a context-sensing component that recognizes meetings in a typical office environment. Our prototype detects the meeting start and end by combining outputs from pressure and motion sensors installed on the chairs. We developed a telephone controller application that transfers incoming calls to voice-mail when the user is in a meeting. Our experiments show that it is feasible to detect high-level context changes with “good enough” accuracy, using low-cost, off-the-shelf hardware, and simple algorithms without complex training. We also note the need for better metrics to measure context detection performance, other than just accuracy. We propose several metrics appropriate for our application in this paper. It may be useful, however, for the community to define a set of general metrics as a basis to compare different approaches of context detection. 1
Decoupled control of a four-leg inverter via a new 4/spl times/4 transformation matrix (2001)

Four-leg (3-phase 4-wire) inverters are developed to power unbalanced/nonlinear three-phase loads. A unique 4/spl times/4 decoupling transformation matrix is used that enables direct transformation between the four degree-of-freedom (DOF) leg-modulation space of the inverter and its corresponding 3-DOF output-voltage space. This is analogous to the well-known 3/spl times/3 "abc-qd" transformation developed for the three-leg inverter. Details of this new 4/spl times/4 "Quad" transform are provided, along with a depiction of the voltage-vectors produced. Advanced synchronous-frame control techniques are applied with this 4-to-3 "abcn-qdo" transform to create a UPS-style inverter with sinewave output. Experimental results for an 8.6 kVA prototype inverter are presented.
Energy Performance of 5G-NX Wireless Access Utilizing Massive Beamforming and an Ultra-Lean System Design (2014)

This paper presents the energy performance of a new radio access technology (RAT) component in 5G, here denoted as 5G-NX. The 5G-NX RAT encompasses massive beamforming and an ultra-lean design as two of its key technology components. The user throughput, resource utilization of the cells and daily average area power consumption are evaluated by means of system level simulations in an Asian city scenario, and the results are compared with a traditional LTE deployment using the same network layout. The simulation results indicate that the new 5G-NX system provides much better energy performance compared to LTE and this is primarily due to the ultra-lean design and the high beamforming gain that provides both longer and more efficient component sleep in the network. At expected traffic levels beyond 2020, 5G-NX is shown to decrease the network energy consumption by more than 50% while providing around 10 times more capacity.
Measurement of the ratio of prompt χc to J/ψ production in pp collisions at s=7 TeV (2012)

The prompt production of charmonium χcand J/ψ states is studied in proton–proton collisions at a centre-of-mass energy of root s=7 TeV at the Large Hadron Collider. The χc and J/ψ mesons are identified through their decays χc→J/ψγ andJ/ψ→μ+μ− using 36 pb−136 pb−1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χc and J/ψ, σ(χc→J/ψγ)/σ(J/ψ), is determined as a function of the J/ψ transverse momentum in the range 2&lt;pT(J/ψ)&lt;15 GeV/c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low pT(J/ψ) region.
Superior Perovskite Oxide‐Ion Conductor; Strontium‐ and Magnesium‐Doped LaGaO 3 : III, Performance Tests of Single Ceramic Fuel Cells (1998)

The performance of La 0.8 Sr 0.2 Ga 0.83 Mg 0.17 O 2.815 (LSGM) as an optimized electrolyte of a solid oxide fuel cell was tested on single cells having a 500‐µm‐thick electrolyte membrane. The reactivity of NiO and LSGM suggested use of an interlayer to prevent formation of LaNiO 3 . The interlayer Sm‐CeO 2 was selected and sandwiched between the electrolyte and anode. Comparison of Sm‐CeO 2 /Sm‐CeO 2 + Ni and Sm‐CeO 2 + Ni as anodes showed that Sm‐CeO 2 /Sm‐CeO 2 + Ni gave an exchange current density 4 times higher than that of Sm‐CeO 2 + Ni. The peak power density of the interlayered cell is 100 mW higher than that of the standard cell without the interlayer. This improvement is due to a significant reduction of the anode overpotential; the overpotential of the cathode La 0.6 Sr 0.4 CoO 3‐delta (LSCo) remained unchanged. Comparison of the peak power density in this study and with that of a previous study, also with a 500‐µm‐thick electrolyte, indicates a factor of 2 improvement, i.e., from 270 mW/cm 2 to 550 mW/cm 2 at 800°C. The excellent cell performance showed that an LSGM‐based thick membrane SOFC operating at temperatures 600° &lt; T op &lt; 800°C is a realistic goal.
Development of a Computational Model of Abscess Formation (2018)

In some bacterial infections, the immune system cannot eliminate the invading pathogen. In these cases, the invading pathogen is successful in establishing a favorable environment to survive and persist in the host organism. For example, <i>S. aureus</i> bacteria survive in organ tissues employing a set of mechanisms that work in a coordinated and highly regulated way allowing: (1) efficient impairment of the immune response; and (2) protection from the immune cells and molecules. <i>S. aureus</i> secretes several proteins including coagulases and toxins that drive abscess formation and persistence. Unless staphylococcal abscesses are surgically drained and treated with antibiotics, disseminated infection and septicemia produce a lethal outcome. Within this context, this paper develops a simple mathematical model of abscess formation incorporating characteristics that we judge important for an abscess to be formed. Our aim is to build a mathematical model that reproduces some characteristics and behaviors that are observed in the process of abscess formation.
Expression of <i>TCL1</i> in Hematologic Disorders (2001)

Risk factors and predictors of immune-related adverse events: implications for patients with non-small cell lung cancer (2022)

In this review, we set out to describe the current state of research regarding potential risk factors for irAE in patients with non-small cell lung cancer, as well as explore the barriers to understanding irAE. We review data from irAE that occur in large phase 3 trials and prospective studies focusing on irAE, as well as the many retrospective studies that currently form the bulk of our understanding of irAE.
Spectral efficiency limitations of maximum ratio transmission in the presence of channel estimation errors (2006)

In this paper, we study the effects of Gaussian channel estimation errors on the achievable spectral efficiency of multiple-input multiple-output (MIMO) systems employing the so-called maximum ratio transmission (MRT) scheme over independent and identically distributed (i.i.d.) Rayleigh fading channels. To that end, we derive the capacity statistics of this transmit-receive diversity scheme. These statistics are valid for arbitrary numbers of transmit and receive antennas and are expressed as a function of the degree of correlation between the actual MIMO channel and its estimated counterpart. Our analytical results are extremely valuable, as they first obviate the need for time-consuming Monte Carlo simulations, with which they are in complete agreement, and second allow to gather insightful information about the impact of estimation errors, which may arise as a result of an imperfect channel estimation process, on the spectral efficiency performance of MRT employed over i.i.d. MIMO Rayleigh fading channels.

<title>True wafer temperature during metallization in physical vapor deposition cluster tools</title> (1994)

Aluminum metallization is an important process for planarization and interconnect applications. Wafer temperature during deposition is one of the key parameter determining film properties such as reflectivity and resistivity. Results of experiments carried out in order to characterize the thermal behavior of product wafers during physical vapor deposition, primarily aluminum and wafer degas will be presented. The effects of back and front side depositions, backside gas pressure and plasma power level on deposition temperature are all investigated. The utility of real time in-situ temperature monitoring on every product wafer in all deposition chambers within a cluster tool and the advantages provided in terms of process monitoring are discussed.
Memory T Cells (2003)

The induction of immunologic tolerance is an important clinical goal in transplantation and autoimmunity. Immunologic tolerance is traditionally defined as specific unresponsiveness to a self- or foreign antigen while maintaining reactivity to other (third party) antigens ([1,2][1][⇓][2]). In the
Permutation Groups (1983)

The Effect of Locking Loops on the Strength of Tendon Repair (1991)

A multiple X-raying method has been developed which allows examination of how the particular features of suturing techniques collapse or pull out of the tendon during tensile testing. This technique was used to examine the locking loop tendon sutures, such as the modified Kessler, Verdan and Ketchum techniques. Locking loops did not contribute towards the strength when small diameter sutures (5/0) of various materials were applied to the tendon, collapsing at 12 Newtons. Larger diameter sutures (4/0) slightly reduced the risk of failure of locking loops, but they still collapsed at 15 Newtons or less, so suture techniques which depend on locking loops will often lead to gap formation at low loads and hence poor results.
The Tecnis ZMA00 diffractive multifocal acrylic lens and the advantage of corneal spherical aberration correcting IOLs (2008)

Purpose: To demonstrate the advantage of multifocal IOLs, designed to compensate for the average spherical aberration of the cornea as the new Tecnis ZMA00 acrylic diffractive lens. Methods: The performance of different multifocal IOLs is studied in a model eye with a physiological cornea. The influence of pupil size is demonstrated by visualizing the light path and the retinal image in the different focal points of the projection of a US Air Force target in monochromatic green and in white light. Lenses to be tested are aspheric and spherical, diffractive and refractive multifocal lenses like the full diffractive Tecnis ZM900 and ZMA00 lenses, the apodized diffractive Acrysof Restor SA60D3 and SN6AD3 lenses and the refractive ReZoom NXG1 multifocal lens. Results: Multifocal IOLs that are corrected for the average corneal spherical aberration and especially the hydrophobic acrylate Tecnis ZMA00 lens show an optical behaviour that is practically independent of pupil size. This is demonstrated for pupil sizes of 3 and 5mm. Conclusions: The Tecnis ZM multifocal lenses are well equipped for patients in different light conditions.
Learning How to Resurface Cam-Type Femoral Heads with Acceptable Accuracy and Precision: The Role of Computed Tomography-Based Navigation (2008)

Only computed tomography-based navigation appears to be appropriate for delivering both the accuracy and the precision needed by surgeons on the steep part of their learning curve. Neither conventional neck-based instrumentation nor imageless navigation provided enough help for novice surgeons learning to perform this technically challenging operation.
Vascular Endothelial Growth Factor Reduced and Connective Tissue Growth Factor Induced by Triamcinolone in ARPE19 Cells under Oxidative Stress (2005)

TA reduced VEGF expression and induced CTGF expression in ARPE19 cells exposed to oxidative stress, and conditioned medium from these cells inhibited tube formation by HUVECs. Because VEGF is a major cytokine involved in angiogenesis, and CTGF is a main cytokine related to fibrosis, these results suggest that changes in their expression may be important mechanisms underlying the decreased choroidal neovascularization and fibrosis after administration of TA.
Etching three-dimensional photonic crystals in GaAs (2005)

We present an efficient method for the fabrication of three-dimensional photonic crystals in GaAs-based materials. The method exploits the dependence of the oxidation rate of AlGaAs on the aluminum content in the alloy. As a result, a wide range of oxidation profiles is possible. The oxidation profiles are determined by the Al concentration profiles in a GaAs/AlGaAs stack grown by molecular beam epitaxy, and the resulting three-dimensional structure depends on the initial two-dimensional pattern defined by standard lithography. We detail the process and present preliminary results showing the viability of the method to realize three-dimensional photonic crystals of various geometries.
