Increasing irradiation temperature maximizes vitamin E grafting and wear resistance of ultrahigh molecular weight polyethylene (2012)

Vitamin E stabilization of radiation crosslinked ultrahigh molecular weight polyethylene (UHMWPE) for total joint implants can be done by blending of UHMWPE resin powder with vitamin E, followed by consolidation and irradiation of the blend. It is well known that vitamin E prevents crosslinking in UHMWPE during ionizing radiation. We hypothesized that there would also be a significant amount of grafting of vitamin E onto UHMWPE during irradiation. Spectroscopic analysis of radiation crosslinked vitamin E-blended UHMWPE before and after extraction with boiling hexane showed vitamin E grafting in up to 30% of the blended vitamin E. Grafting increased with irradiation temperature. We also discovered that increasing irradiation temperature resulted in better preservation of active vitamin E in the polymer and increased crosslinking efficiency of UHMWPE. As a result, warm-irradiated vitamin E-blended UHMWPEs had significantly less wear than those irradiated at ambient temperature. It may be desirable to graft vitamin E on UHMWPE to decrease the possibility of elution and increase long-term stability. Warm irradiation of vitamin E blends may present an advantage in increasing vitamin E potency, as well as decreasing the wear of UHMWPE, which is crucial in decreasing the incidence of periprosthetic osteolysis in total joint replacement patients.
Real-time detection of lymphocytes binding on an antibody chip using SPR imaging (2007)

We demonstrate the use of SPR imaging for the detection of site-specific binding of either B or T lymphocyte populations on an electrochemically-grafted antibody array.
RFIG lamps (2004)

This paper describes how to instrument the physical world so that objects become self-describing, communicating their identity, geometry, and other information such as history or user annotation. The enabling technology is a wireless tag which acts as a radio frequency identity and geometry (RFIG) transponder. We show how addition of a photo-sensor to a wireless tag significantly extends its functionality to allow geometric operations - such as finding the 3D position of a tag, or detecting change in the shape of a tagged object. Tag data is presented to the user by direct projection using a handheld locale-aware mobile projector. We introduce a novel technique that we call interactive projection to allow a user to interact with projected information e.g. to navigate or update the projected information.The ideas are demonstrated using objects with active radio frequency (RF) tags. But the work was motivated by the advent of unpowered passive-RFID, a technology that promises to have significant impact in real-world applications. We discuss how our current prototypes could evolve to passive-RFID in the future.
An attempt at clinically defining and assessing minimally invasive surgery compared with traditional “open” spinal surgery (2011)

It is difficult, if not impossible, to validate that an operative procedure is "less invasive" or "more minimally invasive" than traditional surgical procedures unless one can establish a commonly accepted definition of MIS. Once a consensus definition or precise definition of MIS is agreed upon, the comparison shows a higher infection rate with traditional spinal exposures versus MIS spine procedures.
Rate effects on the microindentation‐based mechanical properties of oxidized, crosslinked, and highly crystalline ultrahigh‐molecular‐weight polyethylene (2004)

The surface micromechanical properties of ultrahigh-molecular-weight polyethylene (UHMWPE) are critical in determining the wear, deformation, and fracture in the surface region. These properties have not been accessible to simple mechanical testing on a spatial scale relevant to these mechanical processes until recently. The structural factors associated with surface mechanical properties (crosslinking, oxidation state, local orientation of polymer, crystallinity, etc.) can be highly variable and localized and may vary on micron spatial scales or smaller. Furthermore, time/frequency-dependent behavior of the surface may have an important role in the overall surface mechanical behavior. Recent work has shown the utility of depth sensing microindentation/nanoindentation testing to interrogate local surface mechanical properties. The goal of the present study was to measure the effect of loading rate on the depth-sensing microindentation testing of UHMWPE. Three different UHMWPE materials (Hylamer, a large crystal material; GUR 1020, a standard medical-grade material; and Marathon, a crosslinked material) were tested using a microindentation method at loading rates ranging from 0.01 to 1 Hz. Similarly, a gamma-irradiated in air and 15-year shelf-aged tibial component was tested through its cross-section to assess the variations in mechanical properties with location and to compare the micromechanical profile with the oxidation profile. It was found that rate of testing affected the microhardness of each material, however, only GUR 1020 and Hylamer showed rate-dependent behavior for modulus and energy dissipation factor. Micromechanical profiles through oxidized regions of the tibial component showed a high correlation with the oxidation profile. Increases in modulus, hardness, and energy dissipation factor were seen with increasing oxidation and each property was loading-rate dependent. These results show that depth-sensing microindentation/nanoindentation testing on the micron scale provides highly consistent and reproducible measurements of surface mechanical properties. This scale of testing minimizes the potential variations caused by local heterogeneity in crystallinity, surface orientation, and other submicron structural features.
Adaptive Machine Vision: What Can Be Learned From Biological Systems (1990)

Biological mechanisms of nonuniform sampling and processing of visual signals, and of automatic gain control are discussed. It is argued that such mechanisms, which result in extensive data reduction and efficient allocation of limited computational resources, are attractive for wide field-of-view machine vision systems.
Study of Chemical Vapor Deposition of Manganese on Porous SiCOH Low-k Dielectrics Using Bis(ethylcyclopentadienyl)manganese (2012)

MnO/MnSiO3-based layers were formed on porous SiCOH low-k dielectrics by Chemical Vapor Deposition (CVD) of Mn from Bisethylcyclopentadienyl manganese. The oxide phase formation is driven by the moisture desorbing from the low-k films. The silicate phase is defined by silanol groups chemisorbed on the low-k surface. The experimental results suggest that formation of thin Mn-based copper diffusion barrier (pore sealing) by CVD is limited to dielectrics having a pore size smaller than the Mn precursor molecules. In the case of larger pore sizes, Mn is deposited inside the dielectric on the pores surface and the layer cannot be a diffusion barrier.
The role of the orbitofrontal cortex in regulation of interpersonal space: evidence from frontal lesion and frontotemporal dementia patients (2016)

Interpersonal distance is central to communication and complex social behaviors but the neural correlates of interpersonal distance preferences are not defined. Previous studies suggest that damage to the orbitofrontal cortex (OFC) is associated with impaired interpersonal behavior. To examine whether the OFC is critical for maintaining appropriate interpersonal distance, we tested two groups of patients with OFC damage: Patients with OFC lesions and patients with behavioral variant frontotemporal dementia. These two groups were compared to healthy controls and to patients with lesions restricted to the dorsolateral prefrontal cortex. Only patients with OFC damage showed abnormal interpersonal distance preferences, which were significantly different from both controls and patients with dorsolateral prefrontal damage. The comfortable distances these patients chose with strangers were significantly closer than the other groups and resembled distances normally used with close others. These results shed light on the role of the OFC in regulating social behavior and may serve as a simple diagnostic tool for dementia or lesion patients.

Cutting Edge: An Antibody Recognizing Ancestral Endogenous Virus Glycoproteins Mediates Antibody-Dependent Cellular Cytotoxicity on HIV-1–Infected Cells (2014)

The failure of antiviral vaccines is often associated with rapid viral escape from specific immune responses. In the past, conserved epitope or algorithmic epitope selections, such as mosaic vaccines, have been designed to diversify immunity and to circumvent potential viral escape. An alternative approach is to identify conserved stable non-HIV-1 self-epitopes present exclusively in HIV-1-infected cells. We showed previously that human endogenous retroviral (HERV) mRNA transcripts and protein are found in cells of HIV-1-infected patients and that HERV-K (HML-2)-specific T cells can eliminate HIV-1-infected cells in vitro. In this article, we demonstrate that a human anti-HERV-K (HML-2) transmembrane protein Ab binds specifically to HIV-1-infected cells and eliminates them through an Ab-dependent cellular cytotoxicity mechanism in vitro. Thus, Abs directed against epitopes other than HIV-1 proteins may have a role in eliminating HIV-1-infected cells and could be targeted in novel vaccine approaches or immunotherapeutic modalities.
Retinal parameters, cortical cerebral microinfarcts, and their interaction with cognitive impairment (2022)

Retinal vascular and neuronal parameters are associated with cortical CMIs, and persons with both pathologies are likely to have cognitive impairment. Further studies may be warranted to evaluate the clinical utility of retinal parameters and CMI in risk prediction for cognitive dysfunction.
Characterization of SiO<sub>2</sub> Aerogel/SiO<sub>2</sub> Fiber Composites Prepared by Sol-Gel Method (2016)

Quartz fiber composites filled with nanosized SiO 2 were prepared by sol-gel method with vacuum impregnation , supercritical drying and surface modification. The silica sol for vacuum impregnated were made from tetraethyl orthosilicate (TEOS), anhydrous ethanol, water and acid catalyst as the starting materials. The water adsorption rate, apparent porosity and electrical properties of composites were investigated by means of archimedes method and waveguide method while the surface area and pore size of the aerogel samples were tested by BET, the mechanism of hydrophobicity was also discussed. The results showed that the moisture absorption rate of products was decreased to 1.21% from 17.36% that without filled with nanosized SiO 2 , with a decreasing range of 93%. Additional coating could make the rate even as low as 0.052%.The dielectric constant had no significant change while the loss tangent decreased from 3.1╳10 -3 to 1.4╳10 -3 ,with a decreasing range of 51.2%.

The magnificent quintet of trinucleotid repeat disorders: Spinal and bulbar muscular atrophy, Huntington’s disease, Friedreich ataxia, myotonic dystrophy, and fragile X syndrome (2019)

Apart from cultural and scientific heritage, human beings can also inherit genetic disorders, such as trinucleotide repeat disorders. These disorders, with the genetic accumulation of repeat sequences, may cause disease in following generation and may lead to even more severe diseases in future generations. Although the formation mechanisms of many of these disorders are known, there are no findings on treatment aside from eliminating symptoms. This review will provide a general and up-to-date overview of some of the trinucleotide repeat diseases.
Facet dependence of leakage current and carrier concentration in m-plane GaN Schottky barrier diode fabricated with MOVPE (Phys. Status Solidi A 8∕2017) (2017)

The background of this cover page shows a superimposed emission microscope image observed from backside of a GaN m-plane Schottky barrier diode with reverse biased condition. It can be observed that the epitaxial layer of m-plane GaN has pyramidal hillocks at the surface, and only facets inclined toward the [0001] direction (+c facet) have emission due to leakage current. Three images at the corner are differential interference contrast microscopy image (upper left), photoluminescence intensity mapping image (PL, upper right), and cathode luminescence image (CL, lower left), respectively, observing the same pyramidal hillocks to investigate the characteristics of each facet. The PL image indicates the intensity of near-band-edge emission (around 363 nm wavelength) of the facets. Details are discussed in the article by Tanaka et al. (no. 1600829). The +c facets have high emission intensity, indicating that there is a high impurity concentration in the +c facets. Furthermore, we consider this is the reason that +c facets have high leakage current. The CL image is a panchromatic image, and facets inclined toward [000-1] direction (−c facet) have lowest emission. Together with PL intensity mapping it can be considered that −c facets have less yellow emission and less impurity concentration.

Urologic Complications of Diabetes (2005)

Diabetes and urologic diseases are very common health problems that markedly increase in prevalence and incidence with advancing age (1–3). Diabetes is associated with an earlier onset and increased severity of urologic diseases, resulting in costly and debilitating urologic complications. Urologic complications, including bladder dysfunction, sexual and erectile dysfunction, as well as urinary tract infections (UTIs), have a profound effect on the quality of life of men and women with diabetes. This review presents a comprehensive overview of the current understanding of clinical and basic research on urologic complications of diabetes and recommendations for future directions for research and clinical care.

Over 50% of men and women with diabetes have bladder dysfunction (4,5). Current understanding of bladder dysfunction reflects a progressive condition encompassing a broad spectrum of lower urinary tract symptoms including urinary urgency, frequency, nocturia, and incontinence. Previously, the dysfunction has been classically described as diminished bladder sensation, poor contractility, and increased postvoid residual urine, termed bladder cystopathy (6). However, bladder cystopathy most likely represents end-stage bladder failure with symptoms of infrequent voiding, difficulty initiating voiding, and postvoid fullness and is relatively uncommon.

A number of clinical studies in men and women with diabetes have reported bladder instability or hypersensitivity as the most frequent finding, ranging from 39–61% of subjects (5,7). Diminished bladder contractility or sensation has been found less often (5), and an acontractile bladder appears to be quite uncommon.

### Bladder dysfunction in women

In women, urinary incontinence is estimated to affect nearly 50% of middle aged and older women, leading to significant distress, limitations in daily functioning, and poorer quality of life (8,9). Diabetes has been identified as an important independent risk factor for incontinence in several large observational studies, including the Nurses’ Health Study, and is associated with 30–100% increased risk (9 …
A Novel Subgenomic Murine Leukemia Virus RNA Transcript Results from Alternative Splicing (2000)

Here we show the existence of a novel subgenomic 4.4-kb RNA in cells infected with the prototypic replication-competent Friend or Moloney murine leukemia viruses (MuLV). This RNA derives by splicing from an alternative donor site (SD') within the capsid-coding region to the canonical envelope splice acceptor site. The position and the sequence of SD' was highly conserved among mammalian type C and D oncoviruses. Point mutations used to inactivate SD' without changing the capsid-coding ability affected viral RNA splicing and reduced viral replication in infected cells.
A handover framework for seamless service support between wired and wireless networks (2006)

This paper proposes low latency handover procedure for seamless connectivity and QoS support between wired (e.g. Ethernet) and wireless (e.g. WLAN, WiBro (802.16-compatible), CDMA) networks by the mobile-assisted and server-initiated handover strategy. It is assumed that the server decides the best target network considering network status and user preferences. In this procedure, a mobile terminal associates with the wireless link decided at the server in advance and receives CoA as well. When handover occurs without the prediction in wired networks, the server performs fast binding update using physical handover trigger through the MIH (media independent handover) function. As a result, a mobile terminal does not need to perform L2 and L3 handover during handover so that this procedure decreases handover latency and loss.
Functional Evaluation of Total Hip Arthroplasty with Five-to Ten-year Follow-up Evaluation (1985)

Forty-seven patients with unilateral hip disease had a preoperative and postoperative gait analysis of total hip arthroplasty with a follow-up period of five to ten years. The object was to correlate the levels of function with mechanical loosening. Unilateral total hip arthroplasty in uncomplicated patients restored function to 80% of normal over a two- to four-year period. Patients followed longer than five years appeared to have an accelerated decline in function unassociated with pain. No Class C patient, regardless of age or gait velocity, developed loosening or required revision of the hip prosthesis. Survivorship studies revealed an 85%-90% incidence of loosening by the seventh postoperative year in Class A patients 55 years or younger and those walking preoperatively at more than 50% of normal gait velocity. In these same two groups of patients, the probability of revision for mechanical failure by ten years is 58% for age and 66% for fast walkers. The majority of patients in this study had a technical rating not acceptable by present standards so that these results represent most likely the worst prognosis for longevity of total hip arthroplasty. In high-risk patients, protected ambulation with crutches for six months postoperation may improve their prognosis.
Metalorganic Chemical Vapor Deposition of Complex Metal Oxide Thin Films by Liquid Source Chemical Vapor Deposition (1996)

The implementation of ferroelectric thin films in advanced semiconductor devices is near; facile integration at ULSI geometries requires chemical vapor deposition (CVD) process technology. The low volatility and thermal stability of many of the existing source reagents has driven the development of liquid source CVD, in which composition is set by volumetric metering of liquids followed by flash vaporization. The methodology as well as early results for Ba 1- x Sr x TiO 3 , Pb 1- x (La x Zr 1- y Ti y ) 1- x /4 O 3 and SrBi 2 Ta 2 O 9 thin films, which are among the best reported for any deposition method, will be reviewed. These results establish liquid source CVD as a leading candidate to become the predominant deposition technology enabling the integration of ferroelectric thin films in ULSI devices.
EH004 (2008)

A MEMS piezoelectric power harvesting device, a unimorph PZT cantilever and arrays with an integrated Si proof mass was designed. Pt/PZT/Pt/Ti/SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> multilayered films were deposited on Si or SOI substrates and then the cantilevers were patterned and released by inductively coupled plasma (ICP) reactive ion etching (RIE).

Photosequencing of Motion Blur using Short and Long Exposures (2020)

Photosequencing aims to transform a motion blurred image to a sequence of sharp images. This problem is challenging due to the inherent ambiguities in temporal ordering as well as the recovery of lost spatial textures due to blur. Adopting a computational photography approach, we propose to capture two short exposure images, along with the original blurred long exposure image to aid in the aforementioned challenges. Post-capture, we recover the sharp photosequence using a novel blur decomposition strategy that recursively splits the long exposure image into smaller exposure intervals. We validate the approach by capturing a variety of scenes with interesting motions using machine vision cameras programmed to capture short and long exposure sequences. Our experimental results show that the proposed method resolves both fast and fine motions better than prior works.

Zinc 5,10,15,20-meso-Tetraferrocenylporphyrin as an Efficient Donor in a Supramolecular Fullerene C60 System (2007)

The supramolecular assembly containing an electron donor, zinc 5,10,15,20-meso-tetraferrocenylporphyrin, and a pyridine-substituted fulleropyrrolidine as an electron acceptor, has been investigated. A comparison of the photophysical properties of the separate components and of the assembled system revealed a photoinduced electron-transfer process from the porphyrin to the fullerene unit. Time-resolved spectroscopy, on the subpicosecond time scale, was performed to determine the rate of the forward and back electron-transfer reactions.
