Ciceribacter lividus gen. nov., sp. nov., isolated from rhizosphere soil of chick pea (Cicer arietinum L.) (2013)

The taxonomic position of strain MSSRFBL1(T), isolated from chickpea rhizosphere soil from Kannivadi, India, was determined. Strain MSSRFBL1(T) formed bluish black colonies, stained Gram-negative and was motile, aerobic, capable of fixing dinitrogen, oxidase-negative and catalase-positive. Q-10 was the major respiratory quinone. Major fatty acids of strain MSSRFBL1(T) were C18 : 1ω7c and C19 : 0cycloω8c. Minor amounts of C18 : 0, C12 : 0, C14 : 0 3-OH, C18 : 0 3-OH, C16 : 0, C16 : 1ω6c/C16 : 1ω7c, C17 : 0 3-OH and C20 : 1ω7c were also present. Polar lipids included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylcholine and two unidentified glycolipids. Bacteriohopane derivatives (BHD1 and 2), diplopterol, diploptene, bishomohopanediol, adenosylhopane and 2β-methyl bacteriohopanetetrol were the major hopanoids of strain MSSRFBL1(T). The genomic DNA G+C content was 71 mol%. EzTaxon-e-based blast analysis of the 16S rRNA gene indicated the highest similarity of strain MSSRFBL1(T) to Ensifer adhaerens LMG 20216(T) (97.3 %) and other members of the genus Ensifer (<96.9 %) in the family Rhizobiaceae of the class Alphaproteobacteria. However, phylogenetic analysis based on 16S rRNA, recA, thrC and dnaK gene sequences showed distinct out-grouping from the recognized genera of the family Rhizobiaceae. Based on phenotypic, genotypic and chemotaxonomic characters, strain MSSRFBL1(T) represents a novel species in a new genus in the family Rhizobiaceae for which the name Ciceribacter lividus gen. nov., sp. nov. is proposed. The type strain of Ciceribacter lividus is MSSRFBL1(T) ( = DSM 25528(T) = KCTC 32403(T)).

Dose-dependent social-cognitive effects of intranasal oxytocin delivered with novel Breath Powered device in adults with autism spectrum disorder: a randomized placebo-controlled double-blind crossover trial (2017)

The neuropeptide oxytocin has shown promise as a treatment for symptoms of autism spectrum disorders (ASD). However, clinical research progress has been hampered by a poor understanding of oxytocin's dose-response and sub-optimal intranasal delivery methods. We examined two doses of oxytocin delivered using a novel Breath Powered intranasal delivery device designed to improve direct nose-to-brain activity in a double-blind, crossover, randomized, placebo-controlled trial. In a randomized sequence of single-dose sessions, 17 male adults with ASD received 8 international units (IU) oxytocin, 24IU oxytocin or placebo followed by four social-cognitive tasks. We observed an omnibus main effect of treatment on the primary outcome measure of overt emotion salience as measured by emotional ratings of faces (η<sup>2</sup>=0.18). Compared to placebo, 8IU treatment increased overt emotion salience (P=0.02, d=0.63). There was no statistically significant increase after 24IU treatment (P=0.12, d=0.4). The effects after 8IU oxytocin were observed despite no significant increase in peripheral blood plasma oxytocin concentrations. We found no significant effects for reading the mind in the eyes task performance or secondary outcome social-cognitive tasks (emotional dot probe and face-morphing). To our knowledge, this is the first trial to assess the dose-dependent effects of a single oxytocin administration in autism, with results indicating that a low dose of oxytocin can significantly modulate overt emotion salience despite minimal systemic exposure.
Co‐extruded polymeric films for gas separation membranes (2013)

ABSTRACT In recent years, gas separation has become an important step in many production process streams and part of final products. Through the use of melt co‐extrusion and subsequent orientation methods, gas separation membranes were produced entirely without the use of solvents, upon which current methods are highly dependent. Symmetric three layer membranes were produced using poly(ether‐block‐amide) (PEBA) copolymers, which serve as a selective material that exhibits a high CO 2 permeability relative to O 2 . Thin layers of PEBA are supported by a polypropylene (PP) layer that is made porous through the use of two methods: (1) inorganic fillers or (2) crystal phase transformation. Two membrane systems, PEBA/(PP + CaCO 3 ) and PEBA/β‐PP, maintained a high CO 2 /O 2 selectivity while exhibiting reduced permeability. Incorporation of an annealing step either before or after orientation improves the membrane gas flux by 50 to 100%. The improvement in gas flux was a result of either elimination of strain induced crystallinity, which increases the selective layer permeability, or improvement of the PP crystal structure, which may increase pore size in the porous support layer. © 2013 Wiley Periodicals, Inc.

The glycoprotein fibulin‐3 regulates morphology and motility of olfactory ensheathing cells in vitro (2008)

The primary olfactory pathway in adult mammals has retained a remarkable potential for self-repair. A specialized glial cell within the olfactory nerve, called olfactory ensheathing cell (OEC), and their associated extracellular matrix are thought to play an important role during regenerative events in this system. To gain insight into novel molecules that could mediate the OEC-supported growth of axons within the olfactory nerve, gene expression profiling experiments were conducted which revealed high expression of the glycoprotein fibulin-3 in OECs. This observation was confirmed with quantitative PCR. In vivo, the distribution of all members of the fibulin family, fibulin-3 included, was localized to the lamina propria underneath the olfactory epithelium, in close association within olfactory nerve bundles. To manipulate fibulin-3 gene expression in cultured OECs, lentiviral vector constructs were designed to either transgenically express or knock-down fibulin-3. Experimental data showed that increased levels of fibulin-3 induced profound morphological changes in cultured OECs, impeded with their migratory abilities and also suppressed OEC-mediated neurite outgrowth. Knock-down of fibulin-3 levels resulted in reduced OEC proliferation. In conclusion, the data provide novel insights into a putative role for fibulin-3 in the regulation of cell migration and neurite outgrowth within the primary olfactory pathway.
Wall Detection Via IMU Data Classification In Autonomous Quadcopters (2021)

An autonomous drone flying near obstacles needs to be able to detect and avoid the obstacles or it will collide with them. In prior work, drones can detect and avoid walls using data from camera, ultrasonic or laser sensors mounted either on the drone or in the environment. It is not always possible to instrument the environment, and sensors added to the drone consume payload and power - both of which are constrained for drones.This paper studies how data mining classification techniques can be used to predict where an obstacle is in relation to the drone based only on monitoring air-disturbance. We modeled the airflow of the rotors physically to deduce higher level features for classification. Data was collected from the drone’s IMU while it was flying with a wall to its direct left, front and right, as well as with no walls present. In total 18 higher level features were produced from the raw data. We used an 80%, 20% train-test scheme with the RandomForest (RF), K-Nearest Neighbor (KNN) and GradientBoosting (GB) classifiers. Our results show that with the RF classifier and with 90% accuracy it can predict which direction a wall is in relation to the drone.
Evaluation of bone geometry in patients sustaining femoral neck fractures (2003)

The purpose of this study is to compare calculated geometric properties of the femoral neck between fractured and nonfractured groups in an effort to more accurately assess patients at risk for femoral neck fracture. A cross-sectional study design was used that compared calculated load bearing capacity of the contralateral proximal femur in hip fracture patients to matched controls. Although not significantly different the average values of bone mineral density and fall index were smaller in the fractured hip group. The ability to calculate cross-sectional moment of inertia and define biomechanical factors of the femoral neck do not appear to be a more accurate assessment of a patients potential to fracture than the standard bone mineral density.

Aerobic Oxidation of N-Alkylamides Catalyzed by N-Hydroxyphthalimide under Mild Conditions. Polar and Enthalpic Effects (2002)

The oxidation of N-alkylamides by O(2), catalyzed by N-hydroxyphthalimide (NHPI) and Co(II) salt, leads under mild conditions to carbonyl derivatives (aldehydes, ketones, carboxylic acids, imides) whose distribution depends on the nature of the alkyl group and on the reaction conditions. Primary N-benzylamides lead to imides and aromatic aldehydes at room temperature without any appreciable amount of carboxylic acids, while under the same conditions nonbenzylic derivatives give carboxylic acids and imides with no trace of aldehydes, even at very low conversion. These results are explained through hydrogen abstraction by the phthalimide-N-oxyl (PINO) radical, whose reactivity with benzyl derivatives is governed by polar effects, so that benzylamides are much more reactive than the corresponding aldehydes. The enthalpic effect is, however, dominant with nonbenzylic amides, making the corresponding aldehydes much more reactive than the starting amides. The importance of the bond dissociation energy (BDE) of the O-H bond in NHPI is emphasized.

Convergent field elastography (2014)

An ultrasound-based system for non-invasive estimation of soft tissue shear modulus will be presented. The system uses a nested pair of transducers to provide force generation and motion measurement capabilities. The outer annular element produces a ring-like ultrasonic pressure field distribution. This in turn produces a ring-like force distribution in soft tissue, whose response is primarily observable as a shear wave field. A second ultrasonic transducer nested inside the annular element monitors the portion of the shear field that converges to the center of the force distribution pattern. Propagation speed is estimated from shear displacement phase changes resulting from dilation of the forcing radius. Forcing beams are modulated in order to establish shear speed frequency dependence. Prototype system data will be presented for depths of 10–14 cm in a tissue phantom, using drive parameters within diagnostic ultrasound safety limits.

Crystal Structures of and Displacive Transitions in OsN2, IrN2, RuN2, and RhN2 (2006)

Unexpected crystal structures: The noble-metal pernitrides OsN2 and IrN2 are found to adopt structure types never before observed in nitrides (see picture; Os/Ir blue, N green). Furthermore, the crystal structures of RuN2 and RhN2, which have yet to be synthesized, are predicted. A pressure-induced displacive phase transition and a semiconductor–metal transition are predicted for IrN2.

Physical Interactive Localization Learning (2022)

Localization is fundamental for mobile robots, especially in unconstrained outdoor environments. Earlier work showed unsupervised localization learning on landmarks to be suitable for large-scale scenes. However, this relied on hand-labeled data to train a CNN for recognizing landmarks. We propose a new approach that allows a robot to learn landmarks for localization with a human cooperatively. This approach uses pre-trained detectors of common objects for learning new landmarks in a scene, requiring only minimal human supervision. Hence, the method bootstraps the landmark learning process and removes the need to manually label large amounts of data. We present localization results using the learned landmarks in simulated and real-world outdoor environments and compare the results to models based on complete images and PoseNet. The landmark-based localization shows improved performance than the baseline methods in challenging scenarios. Our results further show that localization accuracy increases with the number of learned landmarks. The human teacher has complete control over selecting new landmarks, which allows learning unique, robustly detectable, and semantic landmarks.
THICK METAL EBG CELLS WITH NARROW GAPS AND APPLICATION TO THE DESIGN OF MINIATURIZED ANTENNAS (2014)

The paper presents a methodology to achieve efficient low-profile electromagnetic bandgap (EBG) antennas based on thick EBG unit cells. The EBG cells are composed of thick metal patches separated by narrow high aspect ratio (HAR) gaps, and positioned on a PEC-backed substrate. This approach yields new miniaturized EBG cells with considerably reduced electrical size. The miniaturized cells are employed to demonstrate new compact self-excited EBG resonator antennas with considerably reduced operating frequencies. Full-wave simulations and experimental results demonstrate the design approach.
Alterations in the Patella After a High Tibial or Distal Femoral Osteotomy (2001)

Knee osteotomies realign the knee in an attempt to better distribute forces across the knee. The anatomic and physiologic function of the extensor mechanism, which includes the quadriceps tendon, patella, and patella ligament, may be altered during this procedure. An understanding of these changes is important especially when additional surgery becomes necessary, such as a conversion to a total knee arthroplasty. The current authors discuss patella mechanics and changes in the patella associated with osteotomies about the knee and the influence on normal patella biomechanics. Although patella changes are uncommon after a distal femoral osteotomy, poor total knee arthroplasty outcomes after a high tibial osteotomy attributable to patella alterations exist. Surgical technique during the primary high tibial osteotomy and the conversion to the total knee arthroplasty can reliably improve the final outcome. Rigid internal fixation with early knee mobilization after high tibial osteotomy reduces the incidence of patella baja and improves total knee arthroplasty outcome after a high tibial osteotomy, whereas while patella changes after a distal femoral osteotomy are minimal and largely ignored.
Temporal changes in neurotrophic factors and neurite outgrowth in the major pelvic ganglion following cavernous nerve injury (2015)

Despite nerve-sparing radical prostatectomy, nerve damage and erectile dysfunction (ED) prevail, and preventing neurodegeneration is of great importance. Neurotrophic factors and neurite outgrowth were characterized in major pelvic ganglia (MPG) following bilateral cavernous nerve injury (BCNI). Young male Sprague-Dawley rats underwent sham or BCNI surgery, and the intracavernosal pressure to mean arterial pressure ratio was measured 2, 7, 14, 21, 30, and 60 days following injury (n = 8/group). MPG gene expression (qPCR) and Western blot were performed for glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), neurturin, neurotrophin (NT)-3, NT4, brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor, and activating transcription factor 3 (ATF3). Additional rats were injured, and MPGs were removed 24 hr, 48 hr, 3 days, and 7 days following BCNI (n = 3/group). MPGs were cultured in Matrigel, and neurite outgrowth was measured. Erections were impaired early and improved by 60 days in BCNI rats. GDNF, NGF, BDNF, and ATF3 gene expression was significantly increased and NT3 was decreased in MPGs following BCNI (48 hr to 21 days, P < 0.05). GDNF and NGF protein levels were elevated in 48-hr BCNI rats. MPG neurite outgrowth from 24-hr and 48-hr BCNI was higher than sham (658 ± 19 μm, 607 ± 24 μm, 393 ± 23 μm, respectively, P < 0.05). Further studies examining the roles of neurotrophic factors in modulating signaling pathways may provide therapeutic avenues for neurogenically mediated ED.

Dynamic Multi-View Scene Reconstruction Using Neural Implicit Surface (2023)

Reconstructing general dynamic scenes is important for many computer vision and graphics applications. Recent works represent the dynamic scene with neural radiance fields for photorealistic view synthesis, while their surface geometry is under-constrained and noisy. Other works introduce surface constraints to the implicit neural representation to disentangle the ambiguity of geometry and appearance field for static scene reconstruction. To bridge the gap between rendering dynamic scenes and recovering static surface geometry, we propose a template-free method to reconstruct surface geometry and appearance using neural implicit representations from multi-view videos. We leverage topology-aware deformation and the signed distance field to learn complex dynamic surfaces via differentiable volume rendering without scene-specific prior knowledge like template models. Furthermore, we propose a novel mask-based ray selection strategy to significantly boost the optimization on challenging time-varying regions. Experiments on different multi-view video datasets demonstrate that our method achieves high-fidelity surface reconstruction as well as photorealistic novel view synthesis.
Dielectric Relaxation in Dimethyl Sulfoxide/Water Mixtures Studied by Microwave Dielectric Relaxation Spectroscopy (2009)

Dielectric spectra of dimethyl sulfoxide (DMSO)/water mixtures, over the entire concentration range, have been measured using the transmission line method at frequencies from 45 MHz to 26 GHz and at temperatures of 298-318 K. The relaxation times of the mixtures show a maximum at an intermediate molar fraction of DMSO. The specific structure of mixtures in different concentration regions was determined by the dielectric relaxation dynamics, obtained from the effect of temperature on the relaxation time. A water structure "breaking effect" is observed in dilute aqueous solutions. The average number of hydrogen bonds per water molecule in these mixtures is found to be reduced compared to pure water. The increase in the dielectric relaxation time in DMSO/water mixtures is attributed to the spatial (steric) constraints of DMSO molecules on the hydrogen-bond network, rather than being due to hydrophobic hydration of the methyl groups. The interaction between water and DMSO by hydrogen bonding reaches a maximum at a DMSO molar fraction of 0.33, reflected by the maximum activation enthalpy for dielectric relaxation in this concentration, suggesting the formation of a stoichiometric compound, H2O-DMSO-H2O. In highly concentrated solutions, negative activation entropies are observed, indicating the presence of aggregates of DMSO molecules. A distinct antiparallel arrangement of dipoles is obtained for neat DMSO in the liquid state according to the Kirkwood correlation factor (g(K) = 0.5), calculated from the static permittivity. The similarity of the dielectric behavior of pure DMSO and DMSO-rich mixtures suggests that dipole-dipole interactions contribute significantly to the rotational relaxation process in these solutions.
Significant Lifetime Enhancement in QLEDs by Reducing Interfacial Charge Accumulation via Fluorine Incorporation in the ZnO Electron Transport Layer (2022)

ZnO nanoparticles are widely used for the electron transport layers (ETLs) of quantum dots light emitting devices (QLEDs). In this work we show that incorporating fluorine (F) into the ZnO ETL results in significant enhancement in device electroluminescence stability, leading to LT50 at 100 cd m<sup>-2</sup> of 2,370,000 h in red QLED, 47X longer than the control devices. X-ray photo-electron spectroscopy, time-of-flight secondary ion mass spectroscopy, photoluminescence and electrical measurements show that the F passivates oxygen vacancies and reduces electron traps in ZnO. Transient photoluminescence versus bias measurements and capacitance-voltage-luminance measurements reveal that the CF<sub>4</sub> plasma-treated ETLs lead to increased electron concentration in the QD and the QD/hole transport layer interface, subsequently decreasing hole accumulation, and hence the higher stability. The findings provide new insights into the critical roles that optimizing charge distribution across the layers play in influencing stability and present a novel and simple approach for extending QLED lifetimes.
