Expressy (2016)

Expressiveness, which we define as the extent to which rich and complex intent can be conveyed through action, is a vital aspect of many human interactions. For instance, paint on canvas is said to be an expressive medium, because it affords the artist the ability to convey multifaceted emotional intent through intricate manipulations of a brush. To date, touch devices have failed to offer users a level of expressiveness in their interactions that rivals that experienced by the painter and those completing other skilled physical tasks. We investigate how data about hand movement -- provided by a motion sensor, similar to those found in many smart watches or fitness trackers -- can be used to expand the expressiveness of touch interactions. We begin by introducing a conceptual model that formalizes a design space of possible expressive touch interactions. We then describe and evaluate Expressy, an approach that uses a wrist-worn inertial measurement unit to detect and classify qualities of touch interaction that extend beyond those offered by today's typical sensing hardware. We conclude by describing a number of sample applications, which demonstrate the enhanced, expressive interaction capabilities made possible by Expressy.
Effects of reactant heterogeneity and mixing on catabolite repression in cultures of <i>Saccharomyces cerevisiae</i> (1989)

An experimental study was conducted into the effect of reactant heterogeneity on glucose-fed continuous cultures of S. cerevisiae, The heterogeneity was altered by varying mixing intensity in the nutrient entry region within a static mixing device. Experimental results confirm simulation predictions based upon a simple growth model, showing that mixing in the entry region can govern macroscopic culture behavior. Specifically, at high dilution rates, the biomass concentration was reduced by mixing patterns that increased the size of regions where glucose exceeded the threshold for catabolite repression. Because the size of such repressive regions is not uniquely determined by reactant segregation, the authors argue that in biological systems (and others involving a threshold response) an alternative measure of mixing quality should be used. Conclusions are drawn concerning the simulation of biological reactors for design purposes, and the importance of nutrient delivery systems to reactor performance.
Defective glucose-dependent endoplasmic reticulum Ca2+ sequestration in diabetic mouse islets of Langerhans (1994)

Non-insulin-dependent diabetes mellitus (NIDDM) is a metabolic disease associated with abnormal insulin secretion, the underlying mechanisms of which are unknown. Glucose-dependent signal transduction pathways were investigated in pancreatic islets derived from the db/db mouse, an animal model of NIDDM. After stimulation with glucose (4-12 mM), the changes in intracellular Ca2+ concentration ([Ca2+]i) were different; unlike control islets, db/db islets lacked an initial reduction of [Ca2+]i and the subsequent [Ca2+]i oscillations following stimulation with 12 mM glucose. The severity of these defects in Ca2+ signaling correlated with the age-dependent development of hyperglycemia. Similarly defective glucose-induced Ca2+ signaling were reproduced in control islets by pre-exposure to thapsigargin, a selective inhibitor of endoplasmic reticulum (ER) Ca(2+)-ATPase. Estimation of ATPase activities from rates of ATP hydrolysis and by immunoblot hybridization with an antiserum directed against the sarco/endoplasmic reticulum Ca(2+)-ATPase both demonstrated that the ER Ca(2+)-ATPase was almost entirely absent from db/db islets. The effects of inhibition of ER Ca(2+)-ATPase on insulin secretion were also examined; a 4-day exposure of control islets to 1 microM thapsigargin resulted in basal and glucose-stimulated insulin secretion levels similar to those found in db/db islets. These results suggest that aberrant ER Ca2+ sequestration underlies the impaired glucose responses in the db/db mouse and may play a role in defective insulin secretion associated with NIDDM.
Magnetic resonance imaging of intracranial tumors using gadolinium-DTPA. Initial experience with fast imaging. (1986)

One hundred and fifty gadolinium(Gd)-DTPA studies in patients with intracranial tumors were performed. In meningiomas (n = 37) Gd-DTPA is useful to delineate isointense tumors. In acoustic neuromas (n = 16) Gd-DTPA helps to identify intracanalicular tumor tissue. In pituitary adenomas (n = 16) para- or suprasellar tumor extension can be better appreciated after Gd-DTPA injection. In glioblastomas (n = 23) Gd-DTPA provides data on differential diagnosis through the characteristic shape of enhancement. In a variety of tumor types the high contrast between enhancing tumor tissue and adjacent structures facilitates therapy planning. Fast imaging sequences now allow for dynamic Gd-DTPA studies. The time-course of enhancement may increase specificity of magnetic resonance imaging.
Management of venous thromboembolism in cancer patients. (2000)

Venous thromboembolism is a common complication in patients with cancer. The management of deep-vein thrombosis and pulmonary embolism can be a considerable challenge in these patients. Diagnosing venous thrombosis requires objective testing, and noninvasive investigations may be less accurate in patients who have cancer than in those who do not. Treatment of acute venous thrombosis at home with low-molecular-weight heparin is an attractive option in patients with malignant disease, in whom quality of life is especially important. Comorbid conditions, warfarin resistance, difficult venous access, and a potentially high bleeding risk are some of the factors that often complicate the prolonged course of anticoagulant therapy needed in this group. In addition, the use of central venous catheters is increasing, but the optimal treatment of catheter-related thrombosis remains controversial. This article reviews the current diagnostic and treatment approaches to venous thromboembolism in patients with cancer and provides several clinical scenarios to illustrate and discuss some common management problems.

Trailing Shield Head Recording in Discrete Track Media (2006)

Magnetic recording in perpendicular media using write heads with trailing shields was simulated. The recording performance of discrete track media and continuous media was compared. Trailing shields increase the head field gradient, leading to sharper transitions and higher signal-to-noise ratio (SNR). The optimum trailing shield gap was determined to be 30 nm for both types of media. Using such a write head and subject to the condition of no adjacent track erasure the discrete track media SNR was 1.5 dB higher than the continuous media at a linear density of 1700 kfci

Erythro-PmBs: A Selective Polymyxin B Delivery System Using Antibody-Conjugated Hybrid Erythrocyte Liposomes (2022)

As a result of the growing worldwide antibiotic resistance crisis, many currently existing antibiotics have become ineffective due to bacteria developing resistive mechanisms. There are a limited number of potent antibiotics that are successful at suppressing microbial growth, such as polymyxin B (PmB); however, these are often deemed as a last resort due to their toxicity. We present a novel PmB delivery system constructed by conjugating hybrid erythrocyte liposomes with antibacterial antibodies to combine a high loading efficiency with guided delivery. The retention of PmB is enhanced by incorporating negatively charged lipids into the red blood cells' cytoplasmic membrane (RBC<sub><i>cm</i></sub>). Anti-<i>Escherichia coli</i> antibodies are attached to these hybrid erythrocyte liposomes by the inclusion of DSPE-PEG maleimide linkers. We show that these erythro-PmBs have a loading efficiency of ∼90% and are effective in delivering PmB to <i>E. coli</i>, with values for the minimum inhibitory concentration (MIC) being comparable to those of free PmB. The MIC values for <i>Klebsiella aerogenes</i>, however, significantly increased well beyond the resistant breakpoint, indicating that the inclusion of the anti-<i>E. coli</i> antibodies enables the erythro-PmBs to selectively deliver antibiotics to specific targets.
Drift-Reducing Nozzle Effects on Herbicide Performance<sup>1</sup> (2001)

Herbicide efficacy, coverage, and retention were evaluated for spray applied through Drift Guard, Turbo TeeJet, AI TeeJet, and TurboDrop drift-reducing nozzles compared to a conventional flat-fan nozzle. Percentage spray coverage detected on water-sensitive cards was greater for conventional and Drift Guard nozzles than for Turbo TeeJet, AI TeeJet, and TurboDrop nozzles. Spray without adjuvants was retained better by redroot pigweed for treatments applied with conventional and Drift Guard nozzles than Turbo TeeJet, AI TeeJet, and TurboDrop nozzles. However, spray with adjuvants was retained similarly for all nozzle types when averaged over spray adjuvant and two weed species. The efficiency of spray retention was greater for spray applied in 47 than in 190 L/ha spray volume for all nozzles. Paraquat and glyphosate, representing contact and translocated herbicides, respectively, provided similar grass species control for all nozzle types, regardless of spray volume. Paraquat and glyphosate were also equally or more effective in 47 compared to 190 L/ha spray volume.Nomenclature: Glyphosate; paraquat; common lambsquarters, Chenopodium album L. #3 CHEAL; foxtail millet, Setaria italica (L.)

Simultaneous Rhytidoplasty and Lipoinjection: A Comprehensive Aesthetic Surgical Strategy (1998)

Fat autografting is an accepted technique in the treatment of depressions or augmenting thin soft tissues. Aging soft tissues become thin, among them the subcutaneous fat layer, muscles, and fasciae, and these tissues in addition become flaccid. Therefore, to get better results in rejuvenation plastic surgery, a good alternative is the combination of lifting the flaccid tissues and thickening the thin soft tissues with a lack of contour and definition, which enhances the aspect of the entire face and neck. For 10 years in our practice, we have been combining rhytidoplasty (which includes systematizing superficial musculoaponeurotic system and platysma plication) with lipoinjection, placing thin rolls of autologous fat into the facial and cervical muscles, or at least under the fasciae. The results reveal a very high success rate with few minor complications. Proper diagnosis, patient selection, and adequate surgical technique produce predictable and favorable aesthetic results. A concurrent retrospective study of 357 consecutive patients who underwent simultaneous rhytidoplasty and lipoinjection was conducted over a 10-year period (1985 to 1995). The purpose of this article is to show our experience with this method, including long follow-up observations.
Pixel-based optical fiber tactile force sensor for robot manipulation (2012)

This paper investigates novel tactile sensing concepts of a fiber optic sensor that can be integrated with minimally invasive surgical (MIS) manipulation tools whilst being Magnetic Resonance (MR) compatible. A 3×3 tactile optical fiber sensor was developed, and is able to measure applied normal forces. Forces are converted from the deflections of a set of nine flexures that are connected to a system of mirrors which, in turn, reflect light received from transmitting fibers to detection fibers. The changes in light intensity are ultimately read-out by a camera system. The images received by the camera attached at the end of the detection fibers are then processed on a computer system using Matlab. Employing a calibration process, the applied forces can be related to the number of activated pixels per received fiber image. This system enables an array of tactile flexures to be recorded via a single camera.
Apoptosis, Complement and Systemic Lupus Erythematosus: A Mechanistic View (2003)

Deficiencies in the classical pathway of the complement system have been implicated in the etiology and pathogenesis of systemic lupus erythematosus (SLE) for several decades. Recent advances have suggested that this link is due to a critical role of complement in the recognition and clearance of the cellular remnants of apoptosis. In this review, we summarize the role of apoptosis in generation of an autoimmune response, and we integrate recent advances that link apoptosis, complement activation and the etiopathogenesis of SLE.
QoS-Aware Single Cell Admission Control for UTRAN LTE Uplink (2008)

UTRAN Long Term Evolution (LTE) architecture shall support end-to-end quality of service (QoS). To maintain the QoS of in-progress sessions in a cell it is important to admit a new radio bearer only if all the existing sessions and the new bearer can be guaranteed QoS according to their requirements. Hence admission control (AC) has an important role to play for QoS provisioning. In this paper we propose an AC algorithm for LTE uplink utilizing the fractional power control formula agreed in 3GPP. The proposed AC algorithm is compared with a reference AC algorithm. It is shown that at 10% unsatisfied user probability the carried traffic gain of the proposed AC algorithm can be up to around 29% over the reference AC algorithm. Furthermore, the proposed AC algorithm inherently tunes itself for varying load conditions without additional complexity.
Strategies to Prevent Preterm Birth (2014)

After several decades of research, we now have evidence that at least six interventions are suitable for immediate use in contemporary clinical practice within high-resource settings and can be expected to safely reduce the rate of preterm birth. These interventions involve strategies to prevent non-medically indicated late preterm birth; use of maternal progesterone supplementation; surgical closure of the cervix with cerclage; prevention of exposure of pregnant women to cigarette smoke; judicious use of fertility treatments; and dedicated preterm birth prevention clinics. Quantification of the extent of success is difficult to predict and will be dependent on other clinical, cultural, societal, and economic factors operating in each environment. Further success can be anticipated in the coming years as other research discoveries are translated into clinical practice, including new approaches to treating intra-uterine infection, improvements in maternal nutrition, and lifestyle modifications to ameliorate maternal stress. The widespread use of human papillomavirus vaccination in girls and young women will decrease the need for surgical interventions on the cervix and can be expected to further reduce the risk of early birth. Together, this array of clinical interventions, each based on a substantial body of evidence, is likely to reduce rates of preterm birth and prevent death and disability in large numbers of children. The process begins with an acceptance that early birth is not an inevitable and natural feature of human reproduction. Preventative strategies are now available and need to be applied. The best outcomes may come from developing integrated strategies designed specifically for each health-care environment.
Primitive hematopoietic cells in murine bone marrow express the CD34 antigen (1996)

The CD34 antigen is expressed on most, if not all, human hematopoietic stem cells (HSCs) and hematopoietic progenitor cells, and its use for the enrichment of HSCs with repopulating potential is well established. However, despite homology between human and murine CD34, its expression on subsets of primitive murine hematopoietic cells has not been examined in full detail. To address this issue, we used a novel monoclonal antibody against murine CD34 (RAM34) to fractionate bone marrow (BM) cells that were then assayed in vitro and in vivo with respect to differing functional properties. A total of 4% to 17% of murine BM cells expressed CD34 at intermediate to high levels, representing a marked improvement over the resolution obtained with previously described polyclonal anti-CD34 antibodies. Sixty percent of CD34+ BM cells lacked lineage (Lin) markers expressed on mature lymphoid or myeloid cells. Eighty-five percent of Sca-1+Thy-1(10)Lin-/10 cells that are highly enriched in HSCs expressed intermediate, but not high, levels of CD34 antigen. The remainder of these phenotypically defined stem cells were CD34-. In vitro colony-forming cells, day-8 and -12 spleen colony-forming units (CFU-S), primitive progenitors able to differentiate into B lymphocytes in vitro or into T lymphocytes in SCID mice, and stem cells with radioprotective and competitive long-term repopulating activity were all markedly enriched in the CD34+ fraction after single-parameter cell sorting. In contrast, CD34-BM cells were depleted of such activities at the cell doses tested and were capable of only short-term B-cell production in vitro. The results indicate that a significant proportion of murine HSCs and multilineage progenitor cells express detectable levels of CD34, and that the RAM34 monoclonal antibody is a useful tool to subset primitive murine hematopoietic cells. These findings should facilitate more direct comparisons of the biology of CD34+ murine and human stem and progenitor cells.
Rich Pictures: A valuable means to explore complex IS issues (2012)

This paper discusses the value and interpretive risks when using iconography for system understanding using the rich picture tool. It is suggested that a visual language of pictures offers a way of global communication that far exceeds the limitations of text and speech. We argue that a simple graphic can be rapidly communicated, processed and transmitted within a large and culturally diverse audience in a way that is unique to graphic images. We suggest a natural intrinsic grammar belongs to the rich picture in terms of relationships, shape, connectors, context and sub-boundaries.
Modified MAX Phase Synthesis for Environmentally Stable and Highly Conductive Ti <sub>3</sub> C <sub>2</sub> MXene (2021)

One of the primary factors limiting further research and commercial use of the two-dimensional (2D) titanium carbide MXene Ti<sub>3</sub>C<sub>2</sub>, as well as MXenes in general, is the rate at which freshly made samples oxidize and degrade when stored as aqueous suspensions. Here, we show that including excess aluminum during synthesis of the Ti<sub>3</sub>AlC<sub>2</sub> MAX phase precursor leads to Ti<sub>3</sub>AlC<sub>2</sub> grains with improved crystallinity and carbon stoichiometry (termed Al-Ti<sub>3</sub>AlC<sub>2</sub>). MXene nanosheets (Al-Ti<sub>3</sub>C<sub>2</sub>) produced from this precursor are of higher quality, as evidenced by their increased resistance to oxidation and an increase in their electronic conductivity up to 20 000 S/cm. Aqueous suspensions of stoichiometric single- to few-layer Al-Ti<sub>3</sub>C<sub>2</sub> flakes produced from the modified Al-Ti<sub>3</sub>AlC<sub>2</sub> have a shelf life of over ten months, compared to 1 to 2 weeks for previously published Ti<sub>3</sub>C<sub>2</sub>, even when stored in ambient conditions. Freestanding films made from Al-Ti<sub>3</sub>C<sub>2</sub> suspensions stored for ten months show minimal decreases in electrical conductivity and negligible oxidation. Furthermore, oxidation of the improved Al-Ti<sub>3</sub>C<sub>2</sub> in air initiates at temperatures that are 100-150 °C higher than that of conventional Ti<sub>3</sub>C<sub>2</sub>. The observed improvements in both the shelf life and properties of Al-Ti<sub>3</sub>C<sub>2</sub> will facilitate the widespread use of this material.
Nanoacorns:  Anisotropically Phase-Segregated CoPd Sulfide Nanoparticles (2004)

The anisotropically phase-segregated CoPd sulfide nanoparticles, named "CoPd nanoacorns", were spontaneously generated by reducing the corresponding metal precursors with 1,2-hexadecanediol in the presence of various alkanethiols. The CoPd nanoacorn consisting of crystalline Co9S8 and amorphous PdSx phases with the Co9S8 (001) plane at their interface was found to spontaneously form through the anisotropic growth of the Co9S8 phase after the generation of PdSx nanoparticles.
Algorithms for Ad-hoc Piconet Topology Initialization Evaluation for the IEEE802.15.3 High Rate WPAN System (2003)

This paper deals with piconet topology issues in IEEE802.15.3 High Rate Wireless Personal Area Network standard. These issues preventing two devices to establish a connection come from the coexistence of two conflicting concepts: ad-hoc networking and centralized coordination. An algorithm for the initialization of the topology of the piconet is proposed. This algorithm leads to a probability higher than 95% of connection success in the whole power emission range defined by the standard
The HIV Protease Inhibitor Nelfinavir Down-Regulates RET Signaling and Induces Apoptosis in Medullary Thyroid Cancer Cells (2014)

Tactile Perceptual Thresholds of Electrovibration in VR (2021)

Haptic sensation plays an important role in providing physical information to users in both real environments and virtual environments. To produce high-fidelity haptic feedback, various haptic devices and tactile rendering methods have been explored in myriad scenarios, and perception deviation between a virtual environment and a real environment has been investigated. However, the tactile sensitivity for touch perception in a virtual environment has not been fully studied; thus, the necessary guidance to design haptic feedback quantitatively for virtual reality systems is lacking. This paper aims to investigate users' tactile sensitivity and explore the perceptual thresholds when users are immersed in a virtual environment by utilizing electrovibration tactile feedback and by generating tactile stimuli with different waveform, frequency and amplitude characteristics. Hence, two psychophysical experiments were designed, and the experimental results were analyzed. We believe that the significance and potential of our study on tactile perceptual thresholds can promote future research that focuses on creating a favorable haptic experience for VR applications.
