Atomic Layer-by-Layer Deposition of Pt on Pd Nanocubes for Catalysts with Enhanced Activity and Durability toward Oxygen Reduction (2014)

An effective strategy for reducing the Pt content while retaining the activity of a Pt-based catalyst is to deposit the Pt atoms as ultrathin skins of only a few atomic layers thick on nanoscale substrates made of another metal. During deposition, however, the Pt atoms often take an island growth mode because of a strong bonding between Pt atoms. Here we report a versatile route to the conformal deposition of Pt as uniform, ultrathin shells on Pd nanocubes in a solution phase. The introduction of the Pt precursor at a relatively slow rate and high temperature allowed the deposited Pt atoms to spread across the entire surface of a Pd nanocube to generate a uniform shell. The thickness of the Pt shell could be controlled from one to six atomic layers by varying the amount of Pt precursor added into the system. Compared to a commercial Pt/C catalyst, the Pd@PtnL (n = 1-6) core-shell nanocubes showed enhancements in specific activity and durability toward the oxygen reduction reaction (ORR). Density functional theory (DFT) calculations on model (100) surfaces suggest that the enhancement in specific activity can be attributed to the weakening of OH binding through ligand and strain effects, which, in turn, increases the rate of OH hydrogenation. A volcano-type relationship between the ORR specific activity and the number of Pt atomic layers was derived, in good agreement with the experimental results. Both theoretical and experimental studies indicate that the ORR specific activity was maximized for the catalysts based on Pd@Pt2-3L nanocubes. Because of the reduction in Pt content used and the enhancement in specific activity, the Pd@Pt1L nanocubes showed a Pt mass activity with almost three-fold enhancement relative to the Pt/C catalyst.
Compositional Effects of Nanocrystalline Lithium Zirconate on Its CO2 Capture Properties (2007)

A soft-chemistry route has been used for preparation of pure and promoted nanocrystalline lithium zirconate with different stoichiometries. The objective of this investigation has been to study the effect of different compositions on the acceptor and optimize the working properties of lithium zirconate. Special attention has been given to study the effect of different Li2O−ZrO2 stoichiometries on the CO2 capture rates. In addition, the partial substitution of Li2O with K2O as a promoter has been addressed. It has been found that both the capture rate and capacity of lithium zirconate depend considerably on the Li2O to ZrO2 ratio. Enhanced capture rates are observed when a deficiency of Li2O is introduced. It is believed that the excess ZrO2 might act as a dispersant and introduce more reactive boundaries. Moreover, the addition of K2O results also in improved capture rates due to the presence of molten carbonates, but lower capacities and poorer stability due to particle coarsening. The present of free ZrO2 seems also beneficial for the stability of K2O-doped acceptors. Therefore, controlling the K:Li:Zr ratio has been found to be crucial for tailoring the properties of lithium zirconate. An optimized composition can result in an acceptor with enhanced capture rates, stability, and higher degree of utilization.

The APOBEC3A/B deletion polymorphism is associated with a decreased risk of endometrial cancer in the Norwegian population.
Evaluation of reservation-arbitrated access schemes for statistical multiplexing of variable-bit-rate video traffic over dual-bus metropolitan area networks (1998)

To address the problem of video communications over 802.6 MANs, a reservation-arbitrated (RA) access protocol is proposed which allows a variable-bit-rate video source to reserve isochronous channels on a bandwidth-on-demand basis. The paper explains the general method of RA access, compares four different schemes of acquiring incremental bandwidth in response to a reservation request, and evaluates the performance of RA access by simulations using two video-source models. Results indicate that RA access provides fair service under a cyclic capturing mechanism, permits statistical multiplexing while providing nearly isochronous transport service, allows a video source to adapt to its reserved bandwidth during network congestion, and facilitates the implementation of layered video coding techniques.
Interaction of Pyrene-Labeled Poly(ethylene imine) with Sodium Dodecyl Sulfate in Aqueous Solution (1999)

The interaction between pyrene-labeled poly(ethylene imine) (PEI−Py), a hyperbranched polymer, and the anionic surfactant sodium dodecyl sulfate (SDS) in aqueous solution was studied using steady-state fluorescence measurements. Fluorescence experiments were carried out with PEI−Py containing approximately one Py group per 900 monomer polymer units (PEI−Py/900) at two different pH and at two polymer concentrations. When SDS was added to the PEI−Py/900, at both pH 6.6 and pH 10, the monomer fluorescence IM increased significantly, with a much less pronounced change in the excimer emission (IE). In the absence of SDS, the monomer intensity is substantially reduced due to quenching of Py* by secondary and tertiary amino groups of the polymer, whereas the excimer emission is less affected. The increase in IM with increasing SDS concentration indicates that SDS molecules protect Py* from quenching, through formation of polymer-bound micelles formed at the sites of the Py groups. In contrast, IE remains practically unchanged (0.3 wt % PEI, pH 6.6) or decreases. The decrease in IE is attributed to disruption of Py aggregates upon their binding to SDS.
Eukaryotic Intron Loss (2003)

Recently, attention has been drawn to eukaryotic genomes with very few introns ( [1][1], [2][2] ) and to the biased position of introns within genes ( [3][3] ). We show here that intron-poor eukaryotes for which genome data is available have a 5′ bias in the position of their introns within genes
COVID-19 as a Magnifying Glass: Exploring the Importance of Relationships as Education Students Learn and Teach Robotics via Zoom (2023)

Ed+gineering, an NSF-funded program, adapted hands-on robotics instruction for online delivery in response to the COVID-19 pandemic. This qualitative multiple case study shares the experiences of participating education students in spring 2021 as they collaborated virtually with engineering students and fifth graders to engineer bioinspired robots in an afterschool technology club adapted to be virtual. The online context reduced the education students’ interactions with people other than the engineering students and fifth graders on their team and thus positioned COVID-19 as a metaphorical magnifying glass amplifying the critical role that these relationships played in influencing the project’s outcomes. Through analyzing short-answer reflections, the researchers observed patterns in the ways the education students’ interactions with their engineering and fifth-grade partners shaped their teaching self-efficacy and intention to integrate engineering and coding. Education students appeared to gain the most self-efficacy from feeling supported by, but not dependent upon, their engineering partners, and from adopting engineering-teaching roles. Satisfying interactions with fifth graders and successful production of functioning robots appeared to enhance education students’ intention to integrate engineering and coding into their future instruction. Education students reported gaining self-efficacy for both engineering and coding during the experience, but were more likely to report feeling confident about teaching engineering than teaching coding at the project’s end. Implications and lessons learned are shared, which may be particularly relevant for educators who prepare elementary education students to teach engineering in K-6 settings.
Introduction (2016)

Abstract This chapter presents the book as a whole, which explores the realities and fantasies of movement in the modernisms of the late nineteenth and early twentieth centuries. The book covers a wide variety of topics related to the geographical spread of modernism in the late nineteenth and early twentieth centuries, and more broadly to the periodization of modernity as a form of life. It includes discussions of borders and diasporas, regionalism, internationalism, and cosmopolitanism. The experience of motion is at the centre of the book: both in new forms of transport and travel in and between modern cities and in techniques and art forms such as photography, cinema, and dance. These all brought together the new physiological aesthetics of the period and new ways of thinking about human motion and emotion.
Paracoccidioides spp. and Histoplasma capsulatum: Current and New Perspectives for Diagnosis and Treatment (2018)

The thermally-dimorphic systemic fungal group includes several important human pathogens: Blastomyces dermatitides, Coccidioides immitis and C. posadasii, Histoplasma capsulatum, Paracoccidioides brasiliensis, P. lutzii, and Talaromyces (Penicillium) marneffei. They usually are geographically restricted and have natural habitats in soil or in plants, and when fungal propagules invade mammalian host by inhalation, they initiate an inflammatory reaction that can result in self-resolution of the infection or cause an acute or chronic disease. In the setting of the AIDS pandemic and the developments in modern medicine, such as immunosuppressive therapy in cancer surgery patients and in transplantation and autoimmune diseases, the incidence of endemic mycoses has progressively increased. Another important factor of the increased incidence of systemic mycoses in certain regions is the progressive devastation of tropical and subtropical forests. In this review, we focus on two of the most important systemic mycoses: paracoccidioidomycosis and histoplasmosis, and their major characteristics in epidemiology, clinical aspects and laboratorial diagnosis.

Improving Short-Term Memory Performance of Healthy Young Males Using Alpha Band Neurofeedback (2019)

To examine whether it was possible to improve short-term memory performance of healthy participants by increasing relative alpha band power (7–11.5 Hz) using neurofeedback, we first converted a commercial EEG device (EmotivEpoc) to a neurofeedback tool and collected data from 11 healthy Turkish male graduate students in five neurofeedback sessions. &nbsp;Before and after neurofeedback training, a memorization task using 10 English words and their Turkish meanings was applied to all participants. &nbsp;The results indicated that 6 out of 11 participants were able to enhance their relative alpha band power with respect to other bands in the frequency spectrum during neurofeedback sessions. &nbsp;Although there was no obvious improvement in their short-term memory performance, we may conclude that neurofeedback training was beneficial for the participants to focus their minds consciously. &nbsp;However, it is not easy to mention that neurofeedback training certainly improved or was irrelevant with short-term memory performance. &nbsp;This study is important in the sense that for such a focused group the use of a commercial, customized low-cost EEG device was shown to be feasible for neurofeedback training sessions.
Yawing of wind turbines with blade cyclic pitch variation (1981)

The purpose of this study was to determine by analysis, model tests, and full-scale experiments whether a two-bladed wind rotor with passive cyclic pitch variation, yawed for the purpose of rotor speed and torque control, has the potential of cost-effective wind energy conversion. A simple mechanism adopted from rotorcraft technology for obtaining passive cyclic pitch variation makes rapid yaw rates possible without causing vibratory hub moments and without producing appreciable out-of-plane blade excursions. A 7.6-m diameter vane-stabilized fully instrumented wind rotor having low blade solidity was operated between May and October 1980, during 41 days for 96 hours. The operational envelope extended to 16m/sec wind velocity, to 45-degree yaw angle power-on and 80-degree yaw angle power-off. The rotor was automatically yawed when 228 rpm at 10-kW rotor power was exceeded. Reverse yawing was performed manually. Within the tested performance envelope, loads and vibrations were low. The rotor ran smoothly even at high yaw angles and at high yaw rates. Performance was good.
Comment on So et al. Autoantibody Reversion: Changing Risk Categories in Multiple-Autoantibody–Positive Individuals. Diabetes Care 2020;43:913–917 (2020)

So et al. (1) have recently published an article in Diabetes Care stating that there is a small percentage of previously multiple-autoantibody–positive type 1 diabetes (T1D) at-risk individuals who reverted to 0 or 1 autoantibody positivity during follow-up visits. Although the proportion of “reverters” to “maintainers” was vastly different, they stated that the risk of progressing to T1D was decreased in these individuals according to the staging of preclinical T1D currently accepted. They went on to say that the 5-year cumulative risk …
Thymoquinone-Induced Tristetraprolin Inhibits Tumor Growth and Metastasis through Destabilization of MUC4 mRNA (2019)

Tristetraprolin (TTP), a well-characterized AU-rich element (ARE) binding protein, functions as a tumor suppressor gene. The purpose of this study was to investigate whether a bioactive substance derived from a natural medicinal plant affects the induction of TTP and to elucidate its mechanism. We examined the effects of natural bioactive materials including Resveratrol (RSV), thymoquinone (TQ) and curcumin on the expression of TTP in cancer cell. TQ derived from a natural plant <i>Nigella sativa</i> increased the expression levels of TTP mRNA and proteins in a dose-dependent manner in gastric and breast cancer cells. TQ-induced TTP increased the instability of MUC4 mRNA by direct binding of TTP to ARE in the 3'UTR of MUC4 mRNA. The induction of TTP by TQ also reduced the proliferation, migration and invasion of cancer cells. The expression of the epithelial-mesenchymal (EMT)-related genes, which were target genes of TTP, was also decreased by the TQ treatment. In the in vivo experiments using mouse melanoma cells, TQ-induced TTP inhibited metastasis of tumor cells. We have found that TQ-induced TTP might inhibit metastasis by reducing tumor cell migration and invasion through destabilization of MUC4 mRNA, which suggest the MUC4 as a novel target to TTP.
Detection of Acoustic Emission Signals in the Frequency Range up to 100 MHz (1991)

In the literature there have appeared a lot of works with regard to acoustic emission (AE) signals observed in a frequency range below a few MHz. In this paper we describe a new system for measuring AE signals in the frequency range up to 100 MHz. By using piezoelectric thin-film transducers fabricated on the end surfaces of rectangular bars of glass samples which have been notched, the AE signals radiated from the crack can be detected during conventional three point bending test. The output signal of each transducer is amplified and A/D converted at a sampling rate of 200 MHz. The power spectrum of each AE signal and the coherence function between the two signals are obtained by using a computer. The new AE measurement system in VHF range developed here can be applied in a new research field to be called micro-AE spectroscopy.

Compact and fully collinear light source for broadband multiplex CARS microscopy covering the fingerprint region (2015)

Compact and fully collinear light source for multiplex coherent anti-Stokes Raman scattering (CARS) microscopy was proposed and demonstrated. It consists of only a microchip laser, a short photonic crystal fiber, and a longpass filter. It offers performance of sensitivity, bandwidth, and spectral resolution suitable for biomedical applications, especially covering the entire fingerprint region (500-1800 cm(-1)). It can be readily implemented by a commercially available microchip laser and a photonic crystal fiber. It has great potential to expand the utility of CARS microscopy to a wide variety of fields such as endoscopy.

Molecular Diagnostics and the Changing Face of Point-of-Care (2016)

In vitro diagnostics (IVDs) are undergoing an evolution that is being driven by nucleic acid–based molecular detection technologies, from fully automated, multistep miniaturized platforms that integrate sample prep, detection, and signal amplification into single-step cassettes processed on handheld or portable instrumentation (1, 2), to novel real-time detection chemistries that are platform-agnostic and allow high target multiplexing (3). With simplified laboratory requirements, portable equipment and wireless links to remote health care services, these sophisticated technology platforms have the potential to revolutionize patient testing, putting actionable information rapidly into the hands of the treating clinician during the patient encounter, regardless of where the interaction occurs.
Delayed Bleeding after Rectal Polypectomy: Report of a Case (2009)

Colonoscopic postpolypectomy hemorrhage is occasionally encountered in clinical practice. Delayed postpolypectomy bleeding usually occurs within 7 days after the procedure, but rarely occurs more than 3 weeks. We report a case with a bleeding rectal polyp that underwent colonoscopic polypectomy with occurrence of delayed hemorrhage on the 24th day after polypectomy. Bleeding from the polypectomy site was successfully treated with endoscopic submucosal epinephrine injection. Reviewing the English literatures, this is the second longest time interval between polypectomy and onset of delayed hemorrhage.
Robust detection of voiced segments in samples of everyday conversations using unsupervised HMMS (2012)

We investigate methods for detecting voiced segments in everyday conversations from ambient recordings. Such recordings contain high diversity of background noise, making it difficult or infeasible to collect representative labelled samples for estimating noise-specific HMM models. The popular utility <i>get-f0</i> and its derivatives compute normalized cross-correlation for detecting voiced segments, which unfortunately is sensitive to different types of noise. Exploiting the fact that voiced speech is not just periodic but also rich in harmonic, we model voiced segments by adopting harmonic models, which have recently gained considerable attention. In previous work, the parameters of the model were estimated independently for each frame using maximum likelihood criterion. However, since the distribution of harmonic coefficients depend on articulators of speakers, we estimate the model parameters more robustly using a maximum <i>a posteriori</i> criterion. We use the likelihood of voicing, computed from the harmonic model, as an observation probability of an HMM and detect speech using this unsupervised HMM. The one caveat of the harmonic model is that they fail to distinguish speech from other stationary harmonic noise. We rectify this weakness by taking advantage of the non-stationary property of speech. We evaluate our models empirically on a task of detecting speech on a large corpora of everyday speech and demonstrate that these models perform significantly better than standard voice detection algorithm employed in popular tools.
Dementia (2012)

Dementia is the most common mental disorder contributing greatly to disability, institutionalization, and shorter survival among the older population of both genders. Both the prevalence and incidence of dementia are higher in women than in men after the age of 80. Men and women have different profiles concerning risk factors and outcomes of dementia, with most of them favoring men. Epidemiological and experimental studies have indicated that estrogen would protect against dementia and Alzheimer’s disease. However, evidence is still lacking that hormonal replacement therapy could protect against dementia. The role of male sex hormones for dementia risk has been less investigated. Although the causes of gender differences remain poorly understood, awareness of these differences may help identify persons at risk for dementia, affect its prognosis, and have implications for disease prevention.
Evaluation of Elite Southern Maturity Soybean Breeding Lines for Drought‐Tolerant Traits (2014)

Breeding efforts in soybean [ Glycine max (L.) Merr.] have addressed the challenge of water‐limited yields by incorporating parental stocks which exhibit drought‐tolerant traits. Multiple cycles of empirical selection for improved yielding ability in water‐deficient field environments have produced new generations of adapted breeding lines. However, the impact of this selection process on specific putative drought‐tolerant traits is unknown. The objective of this study was to determine if breeders’ selection of 10 elite lines for high seed yield under dry conditions is associated with the presence of physiological expression of three putative drought‐tolerant traits: (i) limited transpiration rate under high vapor pressure deficit (VPD), (ii) early decrease in transpiration rate with soil drying, and (iii) drought‐tolerant N 2 fixation. Greenhouse experiments were undertaken to characterize each genotypes for their phenotype of each of these three traits. Unlike most soybean cultivars, 9 of the 10 elite lines expressed a limited transpiration rate under elevated VPD. The VPD at which transpiration rate became limited was 1.9 kPa or less. There was no difference among genotypes in the threshold for decline in transpiration rate with soil drying, although all genotypes expressed high thresholds indicating an ability to conserve soil water. All lines expressed drought tolerance in their N 2 fixation rates, which was superior to that commonly observed in soybean. This study demonstrated that mating of parents that expressed a drought trait and multiple rounds of progeny selection based on improved yield under water‐limited conditions resulted in the elite lines expressing improved drought traits.

Increased SEC23A Expression Correlates with Poor Prognosis and Immune Infiltration in Stomach Adenocarcinoma (2023)

We observed the significantly upregulated expression of <i>SEC23A</i> in STAD, an association with disease progression, patients' prognosis and infiltrating immune cell subsets. Thus, we propose <i>SEC23A</i> as an independent prognostic factor with a putative role in immune response regulation in STAD.
