Depth generation method for 2D to 3D conversion (2011)

An efficient depth map generation method is presented for static scenes with moving objects. Firstly, static background scene is reconstructed. Depth map of the reconstructed static background scene is extracted by linear perspective. Then, moving objects are segmented precisely. Depth values are assigned to the segmented moving objects according to their positions in the static scene. Finally, the depth values of the static background scene and the moving objects are integrated into one depth map. Experimental results show that the proposed method can generate smooth and reliable depth maps.
Open air plasma deposited antimicrobial SiOx/TiOx composite films for biomedical applications (2016)

Abstract Open air atmospheric pressure plasma jet (APPJ) enhanced chemical vapour deposition process was used to deposit biocompatible SiO x /TiO x composite coatings. The as deposited films are hydrophilic and show visible light induced photocatalytic effect, which is a consequence of the formation of defects in the TiO x structure due to the plasma process. This photocatalytic effect was verified by the demonstration of an antimicrobial effect under visible light on E. coli as well as by degradation of Rhodamine B. The films are non-cytotoxic as shown by the cytocompatibility tests. The films are conductive to cell growth and are stable in DMEM and isopropanol. The structural evaluation using SEM, EDS and XPS shows a dispersion of TiO x phase in a SiO x CyHz matrix. These analyses were used to correlate the structure-property relationship of the composite coating.
Mobile robot navigation by dynamic path planning (2007)

This paper introduces an obstacle avoidance control for a mobile robot using a single CCD camera and ultrasonic sensors. First, the mobile robot detects an obstacle based on information of both the image and the distance. Then, from the information obtained about the obstacle, the mobile robot generates a trajectory to avoid the obstacle. Finally, the usefulness of our proposed methods is demonstrated by experiments.
HLA-DR4 as a Risk Allele for Autism Acting in Mothers of Probands Possibly During Pregnancy (2009)

The HLA-DR4 gene may act in mothers of children with autism during pregnancy to contribute to autism in their offspring. Further studies are required to confirm these findings.
Design of Blast-Loaded Glazing Windows and Facades: A Review of Essential Requirements towards Standardization (2016)

The determination of the blast protection level of laminated glass windows and facades is of crucial importance, and it is normally done by using experimental investigations. In recent years numerical methods have become much more powerful also with respect to this kind of application. This paper attempts to give a first idea of a possible standardization concerning such numerical simulations. Attention is drawn to the representation of the blast loading and to the proper description of the behaviour of the material of the mentioned products, to the geometrical meshing, and to the modelling of the connections of the glass components to the main structure. The need to validate the numerical models against reliable experimental data, some of which are indicated, is underlined.
Stability of sotalol hydrochloride in extemporaneously prepared oral suspension formulations. (2015)

The physical, chemical, and microbial stabilities of extemporaneously compounded oral liquid formulations of sotalol hydrochloride were studied. Sotalol hydrochloride oral liquid suspensions (5mg/mL) were prepared from commercially available tablets (Betapace) in a 1:1 mixture of Ora-Plus: Ora-Sweet, a 1:1 mixture of Ora-Plus:Ora-Sweet SF, and a 1:2.4 mixture of simple syrup:methylcellulose vehicle. Six batches of each formulation were prepared; three were stored at refrigerated temperature (2 deg to 8 deg C) and three at room temperature (20 deg to 25 deg C). Samples were collected from each batch weekly for 6 weeks, and again at 12 weeks. Samples were analyzed by means of a high-performance liquid chromatographic method, and the concentrations obtained were compared to the theoretical time zero value. Samples were examined for pH, odor, color, and consistency changes. The suspensions also were evaluated for their microbial stability. Sotalol hydrochloride oral liquid suspensions (5mg/mL) were chemically stable for 12 weeks regardless of storage conditions (room temperature or refrigerated). Bacterial growth was not supported by any of the formulations. Suspensions stored at refrigerated temperature retained better physical quality (e.g., odor, color, and consistency) than suspensions stored at room temperature. Overall, this study demonstrates that oral formulations of sotalol hydrochloride can be readily prepared with commercially available vehicles. The method of preparation is relatively simple, the materials are relatively inexpensive, and the products have a shelf-life of at least 12 weeks.
Cardiac Resynchronization Through Selective His Bundle Pacing in a Patient with the So‐Called InfraHis Atrioventricular Block (2005)

We present a case of infraHis AV block in which selective His bundle pacing with His-ventricular conduction through the conduction system was accomplished. While further investigations are developed, this approach may be an alternative for cardiac resynchronization in cases of difficult coronary sinus access.
Study of the Effect of DATEM. 1. Influence of Fatty Acid Chain Length on Rheology and Baking (1999)

To answer the question of which fatty acid residue is the most effective, diacetyltartaric esters of monoglycerides (DATEMs) with fatty acids of chain lengths 6:0-20:0 were synthesized. The activity of synthesized DATEMs and commercial DATEM products was studied by means of rheological methods and a microscale baking test with 10 g of flour. Variation of the acyl residue from 6:0 to 22:0 showed that stearic acid (18:0) had the best effect on the baking activity of DATEM (loaf volume increased by 62%). DATEMs containing unsaturated fatty acids (18:1, 18:2) or DATEMs produced from diacylglycerols instead of monoacylglycerols showed a slight increase of the loaf volumes. A slight effect of DATEM on the rheology of dough was observed. However, much greater was the effect on the gluten isolated from doughs prepared with DATEM. The resistance of gluten to extension was increased after the addition of increasing amounts of DATEM (0.1-0.5%). Within the series of DATEMs derived from the homologous series of monoacylglycerols the product based on glycerol monostearate (18:0) showed a maximum increase of the gluten resistance.

Organic delta/sup 13/C varies slightly with salinity in microbial mats at Guerrero Negro, Baja California, Mexico: Implications for stromatolite /sup 13/C values (1985)

Organic carbon preserved in Precambrian stromatolites has delta/sup 13/C values typically in the range -19 to -35, whereas microbial mats growing today in marine hypersaline environments have delta/sup 13/C values in the range -6 to -14. This /sup 13/C shift has been attributed to selective preservation of isotopically light organics, a decline in atmospheric CO/sub 2/ levels, or the restriction of microbial stromatolitic communities to hypersaline environments in the Phanerozoic due to grazing pressures in lower salinity environments. The salinity argument requires that the organic delta/sup 13/C of microbial mats increases with salinity, perhaps ranging from -20 to -35 in less saline water to -6 to -14 in hypersaline waters. Microbial mats inhabit those Guerrero Negro salt works ponds with salinities between 5.0 and 13.0%. Carbonate alkalinities in the ponds range from 2.7x10/sup -3/ moles/L (4%) to 3.6x10/sup -3/ moles/L (13%). Microcoleus mats' organic delta/sup 13/C vary from -12.4 to -14.2 with no clear dependence upon salinity. Aphanothece mats appear to be 1 to 2 permil enriched, relative to Microcoleus mats. The data suggest that salinity effects are insufficient by themselves to cause the /sup 13/C differences observed between Precambrian stromatolites and modern microbial mats.
Formation of Azaborines by Photoelimination of B,N‐Heterocyclic Compounds (2013)

Highly fluorescent π-conjugated polycyclic azaborines can be prepared from B,N-heterocyclic compounds with a BR2 -CH2 unit through the elimination of an R-H molecule (see scheme). These clean photoelimination reactions occur both in solution and in polymers doped with the precursors.
The effect of prostate brachytherapy technique on quality of life outcomes: 5-year outcomes of a prospective cohort study. (2014)

166 Background: Brachytherapy (BT) is widely used to treat clinically localized prostate cancer, but techniques vary and may affect patient outcomes. Methods: We prospectively studied three Boston-area patient cohorts who received different BT techniques: MRI guided, target volume avoids transition zone (MRBT) and two cohorts using standard imaging and planning techniques (USBT 1 and USBT 2 ). We surveyed patients pretreatment and at intervals after, using the validated PCSI scales for urinary incontinence (incont), obstruction/irritation (obstir) bowel problems, sexual dysfunction and the effect of incont on their lives (incontQOL). Based on early results showing increased acute urinary toxicity, USBT 2 providers adopted an element of USBT 1 technique. We report final 5-year follow-up. Results: Of 286 eligible patients, 73 MRBT patients and 190 USBT patients (99 USBT 1 and 91 USBT 2 patients) completed at least 3-month surveys. Patient differed by age (median: MRBT 65.3 years vs. USBT 68.3 p=0.005, USBT 2 65.3 vs. USBT 1 68.3 p=0.004) and education (MRBT 8%≤high school vs. USBT 23%, p&lt;0.001) but other demographic and clinical variables were similar. MRBT patients had more pretreatment obstir symptoms and better sexual function pretreatment. USBT 2 patients had greater increases in acute (3-month) obstir (28.8 vs. 20.0, p=0.01) and incont (12.2 vs. 7.1, p=0.01) than USBT 1 but not bowel or sexual dysfunction, and all outcomes were similar at 5 years. Changing USBT 2 technique eliminated the acute urinary differences. Compared to MRBT, USBT patients had greater increases in acute urinary morbidity (obstir 28.8 vs. 20.0, p=0.01; incont 9.6 vs. 2.2, p=0.002; incontQOL 10.2 vs. 2.4, p=0.0002) and long-term incontinence (incont 7.5 vs. 3.3, p=0.05; incontQOL 5.6 vs. 1.2, p=0.01). Other outcomes did not differ. Conclusions: QOL outcomes vary by BT technique. Measuring QOL may provide useful information for patients choosing treatment and providers assessing their technique. Clinical trial information: NCT00681694.

Phase-Changing Bistable Electroactive Polymer Exhibiting Sharp Rigid-to-Rubbery Transition (2015)

A phase-changing polymer comprising stearyl acrylate and a long-chain urethane diacrylate was studied as a new bistable electroactive polymer. The abrupt and reversible phase transition of the crystalline aggregates of the stearyl moieties results in a rapid shift between the rigid and rubbery states of the polymers during temperature cycles. The transition temperature is tunable between 34–46 °C. A storage modulus change of ∼1000 fold can be obtained within a narrow temperature range of 10 °C. The polymer shows excellent shape memory properties with both fixation rate and recovery rate close to 100%. Diaphragm actuators based on the polymer thin films were electrically actuated up to 70% strain at 50 °C. The actuated shape can be “frozen” after the films were allowed to cool below the transition temperature. This rigid-to-rigid deformation is refreshable and repeatable via the rigid-to-rubbery transition and electrical actuation in the rubbery state.
Microstructure and photocatalytic activity of TiO2-SiO2 composite materials (2020)

Abstract TiO 2 -SiO 2 composite materials with different composition (from 0 to 50 mol % SiO 2 ) were prepared by sol-gel method. Microstructure, optical property and photocatalytic activity of TiO 2 -SiO 2 composite materials were characterized by Raman scattering, ultraviolet-visible (UV-vis) spectrometer and photocatalytic degradation of methylene blue. The Raman spectra results showed that TiO 2 -SiO 2 composite materials contained only a single crystalline phase of anatase TiO 2 . It also indicated the inclusion of SiO 2 suppressed the growth of anatase TiO 2 . The UV-vis absorption spectra showed that the absorption edge of TiO 2 -SiO 2 composite materials has a blue shift as the SiO 2 increased. The optical band gap of TiO 2 -SiO 2 increased from 3.06 eV to 3.32 eV for TiO 2 and 0.5TiO 2 -0.5SiO 2 . The adsorption performance and photocatalytic activity of TiO 2 -SiO 2 was enhanced with the increase of SiO 2 content. 0.5TiO 2 -0.5SiO 2 has the best absorption performance and photocatalytic activity in our experiment. And it has potential application value in the field of photocatalytic materials.
Effective Synthesis of Chiral N‐Fluoroaryl Aziridines through Enantioselective Aziridination of Alkenes with Fluoroaryl Azides (2013)

The CoII complex of a D2-symmetric chiral porphyrin ([Co(D2-Por*)], see scheme) is a highly effective catalyst for the enantioselective aziridination of alkenes with fluoroaryl azides. The reaction can be performed at RT with low catalyst loading, and the olefin is the limiting reagent. Furthermore, the reaction is tolerant toward different combinations of aromatic olefins and fluoroaryl azides.

Oncogenic Tyrosine Kinases, DNA Repair and Survival: The Role of Bcl-xL Deamidation in Transformation and Genotoxic Therapies (2004)

Dysfunctional tyrosine kinases comprise an important class of oncogenes. We have generated a mouse model in which an oncogenic tyrosine kinase (OTK) causes T-lineage tumors. The model facilitates investigation of early oncogenic events in pretumorigenic thymocytes. The OTK transforms thymocytes by a 'double whammy' mechanism whereby on the one hand it inhibits DNA repair, leading to genomic instability, and on the other blocks DNA damage-induced apoptosis. The OTK-mediated blockade of apoptosis involves inhibition of DNA-damage triggered Bcl-xL deamidation, thereby preserving the protein's pro-survival functions. The pharmaceutical promotion of Bcl-xL deamidation might render cancer cells more sensitive to genotoxic attack.
Bugging the intestinal response to radiation (2005)

A n article by Crawford and Gordon (1) in a recent issue of PNAS describes a new relationship between the gut microbial flora and the host that has importance for understanding how radiation damage is processed by the small intestine. Trillions of diverse microbes colonize the intestine that provide essential functions for host survival (2). In addition to digestion, the gut microbia regulate caloric storage, metabolize xenobiotics, modify the immune system, and regulate postnatal gut development including a network of capillaries in the mesenchyme of the small intestinal villi (3-8). Understanding of the microbehost relationship has been increased by studies on germ-free (GF) mice compared with animals that acquire a microbiota from birth [conventionally raised (CONV-R)] or are initially germ-free and then colonized at various stages of postnatal development or during adult-hood with microflora from CONV-R donors (designated as CONV-D, or “conventionalized”) (3, 5). Crawford and Gordon apply these models to investigate whether the intestinal flora modifies the tissue response of the small bowel to ionizing radiation (IR). IR has been used in cancer therapy for >100 years. Approximately 50% of all cancer patients receive radiotherapy. However, radiation therapy is limited by effects of IR on normal tissues as well as the resistance of tumors to this treatment. Radiation effects on the small intestine limit potentially curative radiation doses from being delivered in whole-abdomen radiotherapy for ovarian cancer and also limit the target volume and dose that can be delivered for other abdominal malignancies such as pancreatic, stomach, and colon cancer (9).

The authors initially studied whether GF mice were more resistant to death from radiation-induced small intestine damage compared with CONV-R controls. Total body radiation was delivered, and bone marrow transplantation was necessary to ensure that the effects of a gastrointestinal death dominated in the …
Simple Strategies for Enhancement of the Strength of Lignin‐Based Nanofibrous Aerogels (2022)

Abstract Solvent fractionated lignin and cellulose nanocrystals (CNCs) are used to create highly resilient nanofiber‐based aerogel materials. Two fractions of softwood kraft lignin (SKL) are combined and subsequently electrospun into nanofibers composed of 99% lignin. Additionally, 5 wt.% of CNCs is added into the fiber, based on the solid lignin weight, to enhance the physical properties of the nanofiber materials. The manufacturing process involves dispersing the fibers in water followed by freeze‐drying and subsequent heat treatment. The heat treatment process, with carefully chosen blends of fractionated lignin with specific glass transition temperatures, provides an initial thermoplastic behavior that results in the physical cross‐linking of entangled fibers upon heat treatment. This tailored morphology shows four times higher compressive strength compared to lignin nanofiber materials that only contain high molecular weight fractions. Moreover, CNC is a critical additive that helps maintain fiber geometry by reducing significant softening of lignin under elevated temperatures. Therefore, the fibers with CNC additives ensure the 3D shape after heat treatment, resulting in enhanced physical connections at fiber junctions. As a result, lignin/CNC nanofibers are transformed into 3D structured, lightweight materials that can undergo near full recovery after repeated compressive strain matching the performance of some carbonized analogs.
Nerve ultrasound identifies abnormalities in the posterior interosseous nerve in patients with proximal radial neuropathies (2015)

In radial neuropathy, ultrasound often augments EDx studies and identifies a second lesion in the PIN. Further studies are required to determine the etiology and significance of this additional distal pathology.
Daily Serial Hemodynamic Data During Pregnancy and Seasonal Variation: The BOSHI Study (2012)

Although there are some reports that low plasma volume or increased cardiac output is associated with developing preeclampsia, there are few reports of daily serial hemodynamic data during pregnancy. A total of 37,092 home blood pressure (BP) and heart rate (HR) measurements were obtained from 425 normal pregnant women. Heart rate and shock index (SI) gradually increased by gestational week 32 and then decreased, whereas double product (DP) increased linearly during pregnancy. Although systolic BP and DP were consistently and negatively correlated with daily minimum outside temperature, HR and SI were positively correlated with minimum outside temperature in summer.
Novel Streptomycin and Spectinomycin Resistance Gene as a Gene Cassette within a Class 1 Integron Isolated from Escherichia coli (1999)

The aadA genes, encoding resistance to streptomycin and spectinomycin, have been found as gene cassettes in different gram-negative and gram-positive bacterial species. The present study has revealed the sequence of a new gene, aadA5, integrated as a gene cassette together with the trimethoprim resistance gene dfr7 in a class 1 integron. The integron was located on a plasmid and was identified in a pathogenic porcine Escherichia coli isolate.

Effects of hydrogen and formate on the degradation of propionate and butyrate in thermophilic granules from an upflow anaerobic sludge blanket reactor (1993)

Degradation of propionate and butyrate in whole and disintegrated granules from a thermophilic (55 degrees C) upflow anaerobic sludge blanket reactor fed with acetate, propionate, and butyrate as substrates was examined. The propionate and butyrate degradation rates in whole granules were 1.16 and 4.0 mumol/min/g of volatile solids, respectively, and the rates decreased 35 and 25%, respectively, after disintegration of the granules. The effect of adding different hydrogen-oxidizing bacteria (both sulfate reducers and methanogens), some of which used formate in addition to hydrogen, to disintegrated granules was tested. Addition of either Methanobacterium thermoautotrophicum delta H, a hydrogen-utilizing methanogen that does not use formate, or Methanobacterium sp. strain CB12, a hydrogen- and formate-utilizing methanogen, to disintegrated granules increased the degradation rate of both propionate and butyrate. Furthermore, addition of a thermophilic sulfate-reducing bacterium (a Desulfotomaculum sp. isolated in our laboratory) to disintegrated granules improved the degradation of both substrates even more than the addition of methanogens. By monitoring the hydrogen partial pressure in the cultures, a correlation between the hydrogen partial pressure and the degradation rate of propionate and butyrate was observed, showing a decrease in the degradation rate with increased hydrogen partial pressure. No significant differences in the stimulation of the degradation rates were observed when the disintegrated granules were supplied with methanogens that utilized hydrogen only or hydrogen and formate. This indicated that interspecies formate transfer was not important for stimulation of propionate and butyrate degradation.
