Sensor utilization trade-off areas are identified and sensor/display models are presented. A series of nomograms are provided to assist in performing trade-off analyses.
A comparative study of bearing designs and operational environments for harmonic side-drive micromotors (1993)

The development of flange bearing harmonic side-drive (wobble) micromotors and the results from a comparative study of the operation of flange and center-pin bearing micromotors in different gaseous environments are discussed. The flange and center-pin wobble polysilicon micromotors have been operated with excitations as low as 30 V across 1.5- mu m rotor/stator gaps. Since the flange in the flange bearing design is located at a smaller radius than the bushing in the center-pin bearing design, changes in the frictional parameters of the flange/bushing contact affect the performance of flange bearing micromotors less than that of center-pin bearing micromotors. As a result, flange bearing wobble micromotors show superior performance in gaseous environments over their center-pin counterparts. They can be operated in room air for longer periods and are not significantly affected by the operating environment or by extended storage between operations. The coefficient of friction for polysilicon is observed to change with the operational environment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
The Seeded Growth of Calcium Phosphates on Dentin and Predentin (1977)

The in vitro mineralization of predentin (PD) and of the organic component of dentin (OD) has been studied in a supersaturated solution of calcium phosphate at 37 C and pH = 7.4 at total calcium and phosphate concentrations close to those in vivo. The mineralization of OD can be divided into at least three periods based upon the morphology and the specific surface area of the mineral phase formed. Dissolution of the newly precipitated mineral on OD revealed a stoichiometry close to that for octacalcium phosphate. In contrast, PD was ineffective as a crystal nucleator. The mineralization of the inorganic component of dentin (ID) and whole dentin (D) has also been examined.
Induction of protective immunity to Haemophilus ducreyi in the temperature-dependent rabbit model of experimental chancroid. (1994)

The temperature-dependent rabbit model for chancroid, a sexually transmitted disease caused by the fastidious Gram-negative bacterium Haemophilus ducreyi, was used to investigate the abilities of previous infection and immunization with an acellular preparation of H. ducreyi to induce protective immunity. In the first set of experiments, animals were infected intradermally with either the 35000 or Cha-1 strains of H. ducreyi and then rechallenged 30 days later with both the homologous and heterologous strains. In animals infected with the 35000 strain, statistically significant protective immunity occurred only against the homologous strain, whereas protection against both homologous and heterologous challenge was obtained in rabbits previously infected with strain Cha-1. In a separate series of experiments, rabbits were immunized with cell envelopes from either strain 35000 or strain Cha-1 and then challenged with both the homologous and heterologous strains. In rabbits immunized with strain 35000 cell envelopes, significant protective immunity was observed only against challenge with the homologous strain. In animals immunized with strain Cha-1 cell envelopes, protection was obtained against both homologous and heterologous challenge. Histopathologic analysis of sites inoculated with strain 35000 (10(5) CFU) demonstrated that the inflammatory response in control animals was predominantly suppurative (i.e., heterophilic), whereas that of immunized animals was predominantly mononuclear and, at later time points, largely histiocytic. ELISA and Western blot analyses revealed that immunization produced a better humoral immune response than did infection and provided evidence for antigenic cross-reactivity between these two strains. These results provide the experimental basis for continued efforts to identify potential H. ducreyi vaccinogens.
Breaking Entry- and Species Barriers: LentiBOOST® Plus Polybrene Enables High Transduction Efficacy of Dendritic Cells and Monocytes by Adenovirus 5 (2021)

Abstract Due to their ability to trigger strong immune responses, adenoviruses (HAdVs) in general and the serotype5 (HAdV5) in particular are amongst the most popular viral vectors in research and clinical application. However, efficient transduction using HAdV5 is predominantly achieved in coxsackie and adenovirus receptor (CAR)-positive human cells. In the present study, we used the transduction enhancer LentiBOOST® comprising the polycationic Polybrene to overcome these limitations. Using LentiBOOST®/ Polybrene, we yielded transduction rates higher than 50% in murine bone marrow derived dendritic cells (BMDCs), while maintaining their cytokine expression profile and their capability to induce T-cell proliferation. In human dendritic cells (DCs), we increased the transduction rate from 22% in immature (i)DCs or 43% in mature (m)DCs to more than 80%, without inducing cytotoxicity. While expression of specific maturation markers was slightly upregulated using LentiBOOST®/ Polybrene on iDCs, no effect on mDC phenotype or function was observed. Moreover, we achieved efficient HAdV5 transduction also in human monocytes and were able to subsequently differentiate them into proper iDCs and functional mDCs. In summary, we introduce LentiBOOST® comprising Polybrene as a highly potent adenoviral transduction agent for new in vitro applications in a set of different immune cells in both mice and humans.
A General and Long-Lived Catalyst for the Palladium-Catalyzed Coupling of Aryl Halides with Thiols (2006)

A general catalytic system for the coupling of aryl halides and sulfonates with thiols based on the use of the CyPF-t-Bu ligand (1) is reported. The reactions catalyzed by complexes of 1 occur in excellent yields with broad scope and exhibit extraordinary turnover numbers and high tolerance of functional groups. Turnover numbers usually exceed those of previous catalysts by 2 or 3 orders of magnitude. In addition, the reactions of aryl tosylates with alkane thiols to form aryl sulfides are reported for the first time. Finally, the synthesis of a diarylsulfide from two bromoarenes was accomplished using a hydrogen sulfide surrogate.
The forelimb in walking horses: 1. Kinematics and ground reaction forces (2000)

Video (60 Hz) and force (2000 Hz) data were collected from 5 sound horses during walking. Forelimb data were analysed for 8 strides (4 left, 4 right) per horse to determine sagittal plane kinematics and ground reaction forces (GRFs). The results suggested that brachial rotation was responsible for protraction and retraction of the limb as a whole, while rotations of the scapula and antebrachium elevated the distal limb during breakover and early swing then lowered it in preparation for ground contact. The coffin joint was flexed maximally at the time of peak longitudinal braking force, which occurred during breakover of the contralateral forelimb. The metacarpus was vertical at 28% stride. This was considerably earlier than the change from a braking to a propulsive longitudinal force (34% stride), which coincided with maximal extension of the fetlock joint. The longitudinal propulsive force peaked just after contact of the contralateral forelimb. During the swing phase the joints distal to the shoulder showed a single flexion cycle that peaked at 76% stride at the carpus, 81% stride at the fetlock and 84% stride at the elbow and coffin joints. The coffin and shoulder joints began to extend in the terminal swing phase and continued to extend through ground contact and early stance. The results provide normative data that will be applied in detecting changes in kinematics and ground reaction forces that are associated with specific lamenesses.
Neural Correlates of Indicators of Sound Change in Cantonese: Evidence from Cortical and Subcortical Processes (2016)

Across time, languages undergo changes in phonetic, syntactic and semantic dimensions. Social, cognitive and cultural factors contribute to sound change, a phenomenon in which the phonetics of a language undergo changes over time. Individuals who misperceive and produce speech in a slightly divergent manner (called innovators) contribute to variability in the society, eventually leading to sound change. However, the cause of variability in these individuals is still unknown. In this study, we examined whether such misperceptions are represented in neural processes of the auditory system. We investigated behavioral, subcortical (via FFR), and cortical (via P300) manifestations of sound change processing in Cantonese, a Chinese language in which several lexical tones are merging. Across the merging categories, we observed a similar gradation of speech perception abilities in both behavior and the brain (subcortical and cortical processes). Further, we also found that behavioral evidence of tone merging correlated with subjects’ encoding at the subcortical and cortical levels. These findings indicate that tone-merger categories, that are indicators of sound change in Cantonese, are represented neurophysiologically with high fidelity. Using our results, we speculate that innovators encode speech in a slightly deviant neurophysiological manner, and thus produce speech divergently that eventually spreads across the community and contributes to sound change.
MAuto: Automatic Mobile Game Testing Tool Using Image-Matching Based Approach (2019)

Abstract The exponential increase in the speed of the mobile industry has led to a decreasing quality in many associated mobile apps. Besides, the number of distinct Android devices reached thousands. This challenged the development of universally accepted test applications that can run on all devices. This paper focuses on the development of a new mobile game testing framework, referred to, MAuto . MAuto records the user actions in the game and replays the tests on any Android device. MAuto uses image recognition, through AKAZE features, to record the test cases and the Appium framework to replay the user actions automatically. The feasibility of the developed tool has been demonstrated through testing on the Clash of Clans mobile game.

P015 Familial Prevalence of Serologic Markers of IBD in a Hispanic Cohort (2020)

BACKGROUND: To describe the prevalence of serologic markers in Hispanics with Inflammatory Bowel Disease (IBD) and their unaffected parents. Serum markers evaluated were ANCA, ASCA IgA, ASCA IgG, CBir1, I2, and OmpC. We determined the association of specific markers with diagnoses: Crohn’s disease (CD) vs ulcerative colitis (UC); examined the presence and levels of serum markers in the unaffected parents (familial controls) and compared them with the subjects with IBD (cases). METHODS: Subjects were Hispanic participants in the NIDDK IBD Genetics Research Consortium. We selected a familial cohort of trios (subject plus unaffected parents) and tetrads (2 affected siblings plus unaffected parents). IBD diagnosis was established by standard criteria. Serologic markers were performed using ELISA and reported in EU/ml. The results were classified as positive or negative according to the mean levels of each group. Cutoff values for positive serologies in EU/ml were: ANCA = 35, CBir1 = 30, I2 = 30, ASCA IgA = 20, ASCA IgG = 40 and OmpC = 23. Descriptive statistics was used to summarize continuous variables using mean and standard deviation. Categorical variables were described using frequencies and percentages. The protocol is approved by the MSC-IRB. RESULTS: Of the 286 subjects in the cohort, 98 were cases and 188 were controls. There were 90 trios and 4 tetrads. 64 subjects had CD and 33 had UC. The mean values of individual markers for each study group were assessed. Subjects with UC were positive for ANCA (mean level of 41.79). Subjects with CD were positive for CBir1 (mean = 40.30), I2 (mean = 44.83), ASCA IgG (mean = 43.94) and OmpC (mean = 23.08). The mean values for the parents of both groups were in the negative range. However, within each diagnostic group, several parents had positive antibody titers. Particularly, 18.3% and 21.9% of UC and CD parents, respectively, were positive for I2 and 11.3% and 13% of UC and CD parents, respectively, were positive for OmpC. CONCLUSION: This study suggests that serologic markers in Hispanics with IBD follow the same pattern as that of other ethnic groups. However, the prevalence of positive pANCA is similar for UC and CD, and lower for UC and higher for CD than reported in other groups. Likewise, the prevalence of OmpC in subjects with CD was lower than expected (40.6 vs 55%), as was I2 (40.6% vs 55%). ASCA has also been reported to be present in 20 to 25% of first-degree relatives of patients with CD, whereas our group showed only 13.3%. These discrepancies deserve further study. They may represent genetic differences between populations, but this has not been shown to date in genetic studies. Variation in environmental exposures based in the geographic location of the population is an attractive consideration and may explain the presence of diverse antibodies in parents of both UC and CD subjects.
Data Security in the World of Cloud Computing (2009)

Today, we have the ability to utilize scalable, distributed computing environments within the confines of the Internet, a practice known as cloud computing. In this new world of computing, users are universally required to accept the underlying premise of trust. Within the cloud computing world, the virtual environment lets users access computing power that exceeds that contained within their own physical worlds. Typically, users will know neither the exact location of their data nor the other sources of the data collectively stored with theirs. The data you can find in a cloud ranges from public source, which has minimal security concerns, to private data containing highly sensitive information (such as social security numbers, medical records, or shipping manifests for hazardous material). Does using a cloud environment alleviate the business entities of their responsibility to ensure that proper security measures are in place for both their data and applications, or do they share joint responsibility with service providers? The answers to this and other questions lie within the realm of yet-to-be-written law. As with most technological advances, regulators are typically in a "catch-up" mode to identify policy, governance, and law. Cloud computing presents an extension of problems heretofore experienced with the Internet. To ensure that such decisions are informed and appropriate for the cloud computing environment, the industry itself should establish coherent and effective policy and governance to identify and implement proper security methods.
Toxoplasma gondii infection and chronic schizophrenia: is there any association? (2017)

Background: Toxoplasma gondii (T. gondii) infection has been identified as a risk factor for schizophrenia. Objectives: Herein, we sought to evaluate the association between T. gondii infection and clinical symptoms and quality of life in patients with schizophrenia. Methods: We conducted a cross-sectional study with 48 patients with chronic schizophrenia and 40 controls. Peripheral blood was drawn, and IgM and IgG anti-T. gondii antibodies were evaluated by Enzyme-Linked Immunosorbent Assay (ELISA). Depressive, positive and negative symptoms were assessed, respectively, by the Calgary Depression Scale (CDS) and the Positive and Negative Syndrome Scale (PANSS). Cognitive performance was assessed in patients by the Brazilian version of the Schizophrenia Cognition Rating Scale (SCoRS-BR). Quality of life was assessed by the Brazilian version of the Quality of Life in Schizophrenia scale (QLS-BR). Results: The prevalence and titers of T. gondii IgM and IgG antibodies did not differ between patients and controls. The positive serology for T. gondii IgG antibodies was not associated with illness symptoms, cognitive performance, depressive symptoms or quality of life. Discussion: Our findings suggest that toxoplasmosis infection is not associated with severity of symptoms, quality of life, cognitive or depressive symptoms in schizophrenia patients.
Abstract C108: Evaluating the relationship between physical activity and quality of life in a diverse sample of breast cancer survivors with lymphedema (2023)

Abstract Background: Compared with White breast cancer survivors, Black breast cancer survivors are more likely to experience adverse cancer treatment effects (e.g., pain and swelling from lymphedema) and suboptimal quality of life. Aerobic exercise has been shown to reduce the risk of breast cancer-related lymphedema. Physical activity has been documented to improve quality of life in predominantly White cancer survivors. However, little is known about the benefits of physical activity on quality of life among Black breast cancer survivors. In addition, there is limited evidence on the link between physical activity and quality of life over time by race in breast cancer survivors. Purpose: The primary objective of this study was to investigate the effect of physical activity on quality of life (social wellbeing, emotional/mental wellbeing, and relationship and body image) in White and Black breast cancer survivors with lymphedema. Methods: Linear mixed effects models were tested on an existing data source in a subset of participants in the control and exercise group of a 12-month completed randomized clinical trial. Results: There were 173 participants included in this analysis, averaging 59 years of age; about 33% of the participants were Black women. There were no significant differences in the quality of life outcomes between the control and exercise groups at 12 months. Exercise improved emotional/mental wellbeing and body image as it relates to social barriers at 12 months in Black and White breast cancer survivors, but the changes in these outcomes over time were only statistically significant in White breast cancer survivors (p&amp;lt;0.05). Conclusions: Results show that physical activity can improve certain domains of quality of life (e.g., emotional/mental wellbeing) over time in Black breast cancer survivors. However, the significance of the effect on quality of life (e.g., emotional/mental wellbeing) was isolated to White breast cancer survivors. After further analysis, the effects on quality of life are likely to be significant in a larger sample of Black women. Implications for Cancer Survivors: Physical activity can be used as a non-pharmaceutical intervention to enhance quality of life among subgroups of breast cancer survivors, possibly including Black women.

Panoramic video stitching in multi-camera surveillance system (2010)

This paper concerns the problem of video stitching automatically in a multi-camera surveillance system. Previous approaches have used multiple calibrated cameras for large scale surveillance and monitoring. In this work, we formulate video stitching as a multi-image matching and blending problem, and use SURF to find matches of key points between images, employ homography matrix to calculate overlapping pixels and finally implement boundary resample algorithm to blend images. In addition, camera postures are estimated and fixed automatically according to key points' information. An experimental surveillance system we implemented confirmed the stability and efficiency of our algorithm.
Product design with glass fiber reinforced polymer blends, with potential applications in recycling (1998)

Abstract This paper addresses the issue of compositional variation in multiphase, multi‐component polymer mixtures equivalent to those found in commingled waste streams, such as those obtained from reclamation/recycling operations of post‐consumer containers. By using virgin resins, the effects of variations in the composition of matrices containing high density polyethylene (HDPE) as the major phase on the properties of composites containing varying amounts of glass fiber and different adhesion promoters are studied. The results obtained on injection molded thin‐section parts indicate that it is possible, through the addition of glass fibers and in the presence of suitable adhesion promoters, to obtain enhanced and reproducible properties with relatively little dependence on matrix composition. Preliminary structural and flow analyses were performed with commercial software on different types of plastic parts that could be eventually molded from actual mixed waste plastics suitably modified through glass reinforcement. Experimentally generated rheological and mechanical property data on HDPE based blends containing 20 wt% glass fibers and different adhesion promoters were used for the simulation. Issues concerned with injection molding and product performance of glass‐fiber reinforced blends are discussed.
