Real-time Shadow Removal using a Volumetric Skeleton Model in a Front Projection System (2017)

When a person is located between a display and a projector in operation, a shadow is cast on the display. The shadow on a display may eliminate important visual information and therefore adversely affects the viewing experiences. There have been various attempts to remove shadows cast on a projection display by using multiple projectors. We propose a real time novel approach to removing shadow cast by the person who dynamically interacts with the display making limb motions in a front projection system. The proposed method utilizes a human skeleton obtained from a depth camera to track the posture of the person which changes over time. A model that consists of spheres and conical frustums is constructed based on the skeleton information in order to represent volumetric information of the person being tracked. Our method precisely estimates the shadow region by projecting the volumetric model onto the display. In addition, employment of intensity masks that is based on a distance field helps suppress the afterimage of shadow that appears when the person moves abrubtly and smooth the difference of the brightness caused by different projectors at the boundary of the shadow region.
Dietary uridine enhances the improvement in learning and memory produced by administering DHA to gerbils (2008)

This study examined the effects on cognitive behaviors of giving normal adult gerbils three compounds, normally in the circulation, which interact to increase brain phosphatides, synaptic proteins, dendritic spines, and neurotransmitter release. Animals received supplemental uridine (as its monophosphate, UMP; 0.5%) and choline (0.1%) via the diet, and docosahexaenoic acid (DHA; 300 mg/kg/day) by gavage, for 4 wk, and then throughout the subsequent period of behavioral training and testing. As shown previously, giving all three compounds caused highly significant (P<0.001) increases in total brain phospholipids and in each major phosphatide; giving DHA or UMP (plus choline) produced smaller increases in some of the phosphatides. DHA plus choline improved performance on the four-arm radial maze, T-maze, and Y-maze tests; coadministering UMP further enhanced these increases. (Uridine probably acts by generating both CTP, which can be limiting in phosphatide synthesis, and UTP, which activates P2Y receptors coupled to neurite outgrowth and protein synthesis. All three compounds also act by enhancing the substrate-saturation of phosphatide-synthesizing enzymes.) These findings demonstrate that a treatment that increases synaptic membrane content can enhance cognitive functions in normal animals.
PT015 Association of Ethnicity, Age and Body Size with Electrocardiographic Values in the Community (2014)

The importance of critical thinking is well-documented by the American Association of Colleges of Nursing and the National League for Nursing. Reflective writing is often used to increase understanding and analytical ability. The lack of empirical evidence about the effect of reflective writing interventions on critical thinking supports the examination of this concept.Study objectives were:•To test the effectiveness of a novel reflective writing intervention, based on Paul's (1993) model of critical thinking, for improving critical thinking skills and dispositions in nursing students.•To determine the common characteristics of high-scoring participants.•To determine relationships between scores and institution, gender, age, ethnicity, or experience.This study used an experimental, pretest–posttest design.The setting was two schools of nursing at universities in the southern United States.The convenience sample included 70 fourth-semester students in baccalaureate nursing programs.Randomly assigned control and experimental groups completed the California Critical Thinking Skills Test (CCTST) and the California Critical Thinking Dispositions Inventory Test (CCTDI). The experimental group completed six reflective writing assignments. Both groups completed the two tests again.Results showed that the experimental group had a significant increase (p = 0.03) on the truthseeking subscale of the CCTDI when compared to the control group. The experimental group's scores increased on four CCTST subscales and were higher than the control group's on three CCTST subscales.The results of this study make it imperative for nursing schools to consider including reflective writing—especially assignments based on Paul's (1993) model—in nursing courses. If future studies, testing over longer periods of time, show significant increases in critical thinking, those interventions could be incorporated into nursing curriculum and change the way nurse educators evaluate students.
Optical single-sideband suppressed-carrier modulator for wide-band signal processing (1998)

We develop and demonstrate a technique for implementing a wide-band optical single-sideband suppressed-carrier modulator. The technique relies on a dual-electrode traveling wave modulator for sideband suppression and a Sagnac fiber-loop interferometer for carrier suppression. The implementation uses all commercially available components and demonstrates >40 dB optical carrier suppression, and as much as 60 dB unwanted signal sideband rejection across a 6-20 GHz microwave frequency range. The modulator is used to demonstrate broad-band spectral shifting- and inversion across the 3-18 GHz frequency range.
PD37-01 CONTEMPORARY TRENDS IN TREATMENT PATTERNS FOR MEN DIAGNOSED WITH CLINICALLY LOCALIZED PROSTATE CANCER (2016)

RESULTS: 110 patients were included for analysis from 2005-2015, with mean age 55 and mean length of follow-up at 24 months (6-114). SSR was performed mostly after retropubic sling (70%). Presenting symptoms are listed in the Flow Chart. Mean duration from synthetic sling placement to removal was 54 months (range 1-166). After removal, SUI, UUI, and MUI persisted in 7(47%), 6(23%), and 13(34%) patients respectively, and occurred de novo in 22(20%), 9(8%), and 22(20%) respectively. Of 66 women with dyspareunia, 24(36%) resumed sexual activity. Pelvic pain resolved in 49/80(61%). Women with vaginal sling exposure (21) had no recurrence. UTIs persisted in 24/66(36%). Of 91 women with voiding dysfunction or incomplete emptying before SSR, 10 had persistent voiding dysfunction or incomplete emptying postoperatively requiring additional therapy. 25% were cured following SSR per our ideal outcome (flow chart).
Role of the Lysine-Specific Demethylase 1 in the Proinflammatory Phenotype of Vascular Smooth Muscle Cells of Diabetic Mice (2008)

Insulin resistance and type 2 diabetes are major risk factors for vascular complications. Vascular smooth muscle cells (VSMCs) derived from db/db mice, an established mouse model of type 2 diabetes, displayed enhanced inflammatory gene expression and proatherogenic responses. We examined the hypothesis that aberrant epigenetic chromatin events may the underlying mechanism for this persistent dysfunctional behavior and "memory" of the diabetic cells. Chromatin immunoprecipitation assays showed that levels of histone H3 lysine 4 dimethylation (H3K4me2), a key chromatin mark associated with active gene expression, were significantly elevated at the promoters of the inflammatory genes monocyte chemoattractant protein-1 and interleukin-6 in db/db VSMCs relative to db/+ cells. Tumor necrosis factor-alpha-induced inflammatory gene expression, H3K4me2 levels, and recruitment of RNA polymerase II at the gene promoters were also enhanced in db/db VSMCs, demonstrating the formation of open chromatin poised for transcriptional activation in diabetes. On the other hand, protein levels of lysine-specific demethylase1 (LSD1), which negatively regulates H3K4 methylation and its occupancy at these gene promoters, were significantly reduced in db/db VSMCs. High glucose (25 mmol/L) treatment of human VSMCs also increased inflammatory genes with parallel increases in promoter H3K4me2 levels and reduced LSD1 recruitment. LSD1 gene silencing with small interfering RNAs significantly increased inflammatory gene expression and enhanced VSMC-monocyte binding in nondiabetic VSMCs. In contrast, overexpression of LSD1 in diabetic db/db VSMCs inhibited their enhanced inflammatory gene expression. These results demonstrate novel functional roles for LSD1 and H3K4 methylation in VSMCs and inflammation. Dysregulation of their actions may be a major mechanism for vascular inflammation and metabolic memory associated with diabetic complications.
Generation of Trichoderma harzianum with pyr4 auxotrophic marker by using the CRISPR/Cas9 system (2021)

Trichoderma harzianum is a filamentous fungus used as a biological control agent for agricultural pests. Genes of this microorganism have been studied, and their applications are patented for use in biofungicides and plant breeding strategies. Gene editing technologies would be of great importance for genetic characterization of this species, but have not yet been reported. This work describes mutants obtained with an auxotrophic marker in this species using the CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)/ Cas (CRISPR-associated) system. For this, sequences for a guide RNA and Cas9 overexpression were inserted via biolistics, and the sequencing approach confirmed deletions and insertions at the pyr4 gene. Phenotypic characterization demonstrated a reduction in the growth of mutants in the absence of uridine, as well as resistance to 5-fluorotic acid. In addition, the gene disruption did not reduce mycoparasitc activity against phytopathogens. Thus, target disruption of the pyr4 gene in T. harzianum using the CRISPR/Cas9 system was demonstrated, and it was also shown that endogenous expression of the system did not interfere with the biological control activity of pathogens. This work is the first report of CRISPR Cas9-based editing in this biocontrol species, and the mutants expressing Cas9 have potential for the generation of useful technologies in agricultural biotechnology.
Adolescents and Young Adults with Acute Lymphoblastic Leukemia Have Better Outcomes When Treated with Pediatric-Inspired Regimens - Systematic Review and Meta-Analysis of Comparative Trials (2011)

Abstract Abstract 2591 Background: Survival of adults with acute lymphoblastic leukemia (ALL) is inferior to pediatric patients. Therefore, strategies to improve long-term results in this population are warranted. Objectives: This study aims to evaluate the efficacy and safety of pediatric-inspired regimens given to adolescents and young adults (AYA) with ALL. Methods: Systematic review and meta-analysis of comparative trials of AYA patients with ALL given induction chemotherapy with either pediatric-inspired regimens or conventional adult chemotherapy was conducted. Cochrane Library, MEDLINE and conference proceedings were searched (up-to May, 2011). Outcomes assessed were: all-cause mortality, number of patients achieving complete remission after induction chemotherapy and toxicity of the regimen (evaluated by non-relapse mortality). Relative risks (RR) with 95% confidence intervals (CIs) were estimated and pooled. Results: Our search yielded 11 trials, including 2489 patients. The age of AYA patients ranged between 10 and 57 years. Studies were published between the years 2003 and 2009. AYA patients given pediatric-inspired regimens had a statistically significant lower all cause mortality at 3 years (RR 0.58; 95% CI 0.51–0.79, 7 trials) beyond 3 years (RR 0.58; 95% CI 0.51–0.65, 8 trials) and at the end of study period (RR 0.59; 95% CI 0.52–0.66, 9 trials, Figure). Sensitivity analysis for all cause mortality including studies in which the two cohorts were well compared in either age or disease risk also showed decreased all cause mortality in patients given pediatric-inspired regimen (RR 0.53; 95% CI 0.41–0.70, I2=50%, 4 trials). However, this superiority in survival for pediatric-inspired regimens was not maintained when studies including only patients older than 20 years were analyzed (RR 0.49; 95% CI 0.23–1.06, I2=67%, 2 trials). Complete remission rate after induction chemotherapy was superior in patients given pediatric-inspired regimens when compared to patients given conventional adult chemotherapy (RR 1.05; 95% CI 1.01–1.10, I2=55%, 7 trials) with comparable non-relapse mortality in both groups (RR 0.53; 95% CI 0.19–1.48, I2=56%, 4 trials). Conclusions: For patients up to the age of 20 years, pediatric-inspired regimens are superior to conventional adult chemotherapy in terms of ACM and complete remission rate with similar non relapse mortality. Randomized controlled trials to further investigate the feasibility of this approach in adult ALL patients are warranted. Disclosures: No relevant conflicts of interest to declare.

Peritoneal Dialysis for Patients with Autosomal Dominant Polycystic Kidney Disease (2017)

End-stage renal disease secondary to autosomal dominant polycystic kidney (ADPKD) is a common issue worldwide. Peritoneal dialysis (PD) is a reasonable option for renal replacement therapy for these patients and should not be withheld due to concerns that the patient may not tolerate the fluid volumes in the peritoneal cavity. This review covers the existing data on the outcomes and complications associated with the use of PD in the polycystic kidney disease patient. In general, PD is well tolerated and outcomes in ADPKD patients are equivalent to or better than other patient groups.
On the use of learning-based forecasting methods for ameliorating fashion business processes: A position paper (2022)

The fashion industry is one of the most active and competitive markets in the world, manufacturing millions of products and reaching large audiences every year. A plethora of business processes are involved in this large-scale industry, but due to the generally short life-cycle of clothing items, supply-chain management and retailing strategies are crucial for good market performance. Correctly understanding the wants and needs of clients, managing logistic issues and marketing the correct products are high-level problems with a lot of uncertainty associated to them given the number of influencing factors, but most importantly due to the unpredictability often associated with the future. It is therefore straightforward that forecasting methods, which generate predictions of the future, are indispensable in order to ameliorate all the various business processes that deal with the true purpose and meaning of fashion: having a lot of people wear a particular product or style, rendering these items, people and consequently brands fashionable. In this paper, we provide an overview of three concrete forecasting tasks that any fashion company can apply in order to improve their industrial and market impact. We underline advances and issues in all three tasks and argue about their importance and the impact they can have at an industrial level. Finally, we highlight issues and directions of future work, reflecting on how learning-based forecasting methods can further aid the fashion industry.
Intraoperative infrared functional imaging of human brain (2003)

We hypothesized that it would be possible to detect the distribution of cortical activation by using a sensitive, rapid, high-resolution infrared imaging technique to monitor changes in local cerebral blood flow induced by changes in focal cortical metabolism. In a prospective study, we recorded in 21 patients the emission of infrared radiation from the exposed human cerebral cortex at baseline, during language and motor tasks, and during stimulation of the contralateral median nerve using an infrared camera (sensitivity 0.02 degrees C). The language and sensorimotor cortex was identified by standard mapping methods (cortical stimulation, median nerve somatosensory-evoked potential, functional magnetic resonance imaging), which were compared with infrared functional localization. The temperature gradients measured during surgery are dominated by changes in local cerebral blood flow associated with evoked functional activation. The distribution of the evoked temperature changes overlaps with, but extends beyond, functional regions identified by standard mapping techniques. The distribution observed via infrared mapping is consistent with distributed and complex functional representation of the cerebral cortex, rather than the traditional concept of discrete functional loci demonstrated by brief cortical stimulation during surgery and by noninvasive functional imaging techniques. By providing information on the spatial and temporal patterns of sensory-motor and language representation, infrared imaging may prove to be a useful approach to study brain function.

Design and Analysis of a Robust Carbon Nanotube-Based Asynchronous Primitive Circuit (2013)

Carbon Nanotube Field Effect Transistors (CNFETs) show great promise as extensions to silicon CMOS. However, CNFET-based circuits will face great fabrication challenges that will translate into important parameter variations and decreased reliability. Hence, asynchronous logic, which is intrinsically more robust to variability, seems an ideal and perhaps unavoidable choice for digital circuits in CNFET technology. This article presents the results on the design and analysis of a CNFET-based implementation of an asynchronous circuit primitive: the Muller C-element. Using a CNFET SPICE model, we evaluate the robustness of CNFET-based C-element in the presence of CNT fabrication-related nonidealities. We investigate a quantitative evaluation of how timing variability impacts the functionality of a C-element and then, extract the necessary delay constraints of the C-element circuit from the signal transition graph specification. Considering the large degrees of spatial correlation observed between the CNFETs fabricated on directionally grown CNTs, a layout technique is exploited to overcome the robustness challenges of a CNFET-based C-element. Extensive Monte Carlo simulations on the proposed technique have demonstrated the effectiveness of the proposed CNFET-based C-element by improving approximately 50X in its robustness in expense of 65% area, 47% delay, and 56% power consumption overheads. Experimental results indicate that implementation of some CNFET-based Quasi Delay Insensitive (QDI) benchmark circuits using the proposed C-element results in significant robustness improvement with negligible power and throughput overheads. As a promising step toward CNFET-based giga-scale integrated circuits, this article shows that the asynchronous logic is an effective approach to design robust integrated circuits in CNFET technology with inherent extreme physical variations.
Compressed full-text indexes (2007)

Full-text indexes provide fast substring search over large text collections. A serious problem of these indexes has traditionally been their space consumption. A recent trend is to develop indexes that exploit the compressibility of the text, so that their size is a function of the compressed text length. This concept has evolved into self-indexes , which in addition contain enough information to reproduce any text portion, so they replace the text. The exciting possibility of an index that takes space close to that of the compressed text, replaces it, and in addition provides fast search over it, has triggered a wealth of activity and produced surprising results in a very short time, which radically changed the status of this area in less than 5 years. The most successful indexes nowadays are able to obtain almost optimal space and search time simultaneously. In this article we present the main concepts underlying (compressed) self-indexes. We explain the relationship between text entropy and regularities that show up in index structures and permit compressing them. Then we cover the most relevant self-indexes, focusing on how they exploit text compressibility to achieve compact structures that can efficiently solve various search problems. Our aim is to give the background to understand and follow the developments in this area.
Laser beam welding of thermoplastics (2003)

Current product development showing an ever shrinking physical volume is asking for new, reliable joining technologies. Laser beam technologies conceal innovative solutions to overcome limitations of conventional joining technologies. Laser beam welding of thermoplastics offers several process technical advantages. The joining energy is fed contact-less into the joining area, avoiding mechanical stress and thermal load to the joining partners. The energy is supplied spatially (seam width on the order of 100 &mu;m) and timely (interaction time on the order of ms) very well defined. Different process strategies are possible leading to flexibility, product adapted irradiation, short process times and high quality weld seams as well as to high integration abilities and automation potentials. During the joining process no vibration, no thermal stress, no particle release takes place. Therefore, destruction of mechanically and electronically highly sensitive components, such as microelectronics, is avoided. The work place pollution is neglectable compared to other joining technologies, such as gluing (fume) or ultrasonic welding (noise, pieces of fluff). Not only micro-components can be welded in a reproducible way but also macro-components while obtaining a hermetic sealing with good optical appearance. In this publication firstly, an overview concerning process technical basis, aspects and challenges is given. Next, results concerning laser penetration welding of polymers using high power diode lasers are presented, while comparing contour and simultaneous welding by experimental results and the on-line process monitoring.
