Development of compact and light-weight LRF based positioning sensor for mobile robot localization (2009)

In this paper, we describe our positioning system based ultra-compact Laser Range Finder (LRF) for mobile robot. The system consists of reflectors as landmark and a laser range finder (LRF) named “Pos-URG”. The landmarks are randomly and sparsely placed in environment, and their position and posture are known. Pos-URG has map data which consists of pose information and relation information between each landmark, which are sorted in ascending order of distance value between each other landmarks. When the Pos-URG finds multiple number of landmarks, the set of landmarks in map which correspond the detected landmarks is searched. The searching is done using not only each landmark's position and posture but also relations between them. Then, Pos-URG's position and posture is calculated with coordinate transform from sensor coordinates to map coordinates. The most important characteristic of this proposed searching method is its low computational time and it enables the method to be implemented into low-cost and low-spec CPU which is assembled into Pos-URG.
Searching for the second best graft for coronary artery bypass surgery: a network meta-analysis of randomized controlled trials (2014)

The present network meta-analysis consistently demonstrated an angiographic superiority of RIMA and RA over SVG. The RIMA is expected to achieve a better patency rate than the RA, but further studies are needed.
Gestión del agua en los invernaderos. (2001)

Como es bien conocido, el cultivo en invernadero posibilita una mayor eficiencia en el uso del agua y de la tierra y alta rentabilidad economica. No obstante, la escasez de recursos hidricos, la baja calidad del agua de riego y los problemas ambientales provocados por la lixiviacion de nitratos y pesticidas en toda la cuenca mediterranea, pueden limitar el desarrollo futuro de esta agricultura. Por tanto es necesario mejorar la gestion del agua de riego en los invernaderos. En este articulo se exponen las experiencias y resultados sobre la gestion y optimizacion del agua utilizada para riegos, llevados a cabo en las plantaciones horticolas en invernaderos de la Estacion Experimental Las Palmerillas (Cajamar) de Almeria, y su comparacion con otras plantaciones en el resto del mundo.
Übergangsmetall-Methylen-Komplexe, LI [1]. Carbocyclische Carbene, Carben-Brücken, kleine Kohlenwasserstoff-Liganden und Metallacyclen: Beispiele einer umfassenden Synthesekonzeption / Transition Metal Methylene Complexes, LI [1]. Carbocyclic Carbenes, Carbene Bridges, Small Hydrocarbon Ligands, and Metallacycles: Examples of a General Synthetic Concept (1983)

Abstract Carbene transfer from aliphatic diazoalkanes upon coordinatively unsaturated metal centers is a general synthetic concept that provides straight-forward routes into organo-metallic hydrocarbon chemistry. A comparison focussing on several key reactions of general applicability demonstrates that mononuclear organometal substrates add carbenes that may act as bridging ligands (e.g., compound 6) if they arise from ω,ω'-bisdiazoalkanes. By way of contrast, metal-metal double bonds cleanly form dimetallacyclo-propane-type derivatives under very mild conditions (7-9). The broadest variety of structures is finally encountered with metal-metal triply bonded precursors such as the molybdenum compounds 3: here, the initial diazoalkane adducts are subject to further rearrangement processes commonly leading to metal-metal single bonds (11) or causing irreversible cleavage of the dinuclear metal systems (10).
Stable enhancement for aodv routing protocol (2004)

Routing algorithm has been the challenge in the wireless ad-hoc network for a long time because of the quick mutability of the network topology introduced by the mobility of nodes. AODV is appealing for ad hoc networks as an efficient on-demand routing protocol because of the low routing overhead and high performance. As an optimization for the current AODV, a novel stable adaptive enhancement for AODV routing protocol was proposed in this paper, which considers joint route hop count, node stability and route traffic load balance as the route selection criteria. Comparing with AODV protocol, the new algorithm has better performance as shown with the simulations results.
Is Trauma a Causal Agent of Psychopathologic Symptoms in Posttraumatic Stress Disorder? (2010)

These results support the conclusion that the majority of psychiatric symptoms reported by combat veterans with PTSD would not have been present were it not for their exposure to traumatic events.
A clinical overview of treatment decisions in the management of spasticity (1997)

Spasticity from an upper motor neuron syndrome may cause a variety of symptoms that interfere with function. Decisions regarding spasticity treatment are influenced by the chronicity, severity, and distribution of the spasticity; the locus of injury; the presence and severity of co-morbidities; the availability of support; and the goals of treatment. Not all spasticity can or even should be treated; tone reduction is indicated only if spasticity interferes with some level of function, positioning, care, or comfort. Treatment goals should be well outlined before treatment begins. Botulinum toxin may be used to treat focal spasticity as part of an overall treatment plan.
Plasmonic Titanium Nitride Nano-enabled Membranes with High Structural Stability for Efficient Photothermal Desalination (2021)

Herein, we demonstrate the desalination performance of a solar-driven membrane distillation (MD) process, where upon light illumination, a highly localized heating of plasmonic titanium nitride nanoparticles (TiN NPs) immobilized on a hydrophobic membrane provides the thermal driving force for the MD operation. The engineered TiN photothermal membrane induces vapor generation directly at the feed-membrane interface upon solar irradiation, thereby eliminating the need to heat the entire bulk feed water. The results indicate that the average vapor flux through the TiN photothermal membrane without any auxiliary feed heating was recorded as 1.01 L m<sup>-2</sup> h<sup>-1</sup>, which corresponds to the solar-thermal efficiency of 66.7% under 1 sun solar irradiance. The superior performance of the photothermal MD process is attributed to the broadband optical absorption and excellent light-to-heat conversion properties of the plasmonic TiN NP layer, which enabled efficient interfacial water heating at the membrane surface and increased the net driving force for vapor transport. Results also reveal the high mechanical stability of the TiN photothermal coating layer during long-term photothermal MD operations. We believe that the TiN photothermal membranes fabricated using a relatively inexpensive and nontoxic material via the simple technique with high stability and photothermal conversion efficiency will provide a path forward for developing the solar-driven MD applications.
factors influencing differences of rva ; rvot pacing hemodynamic effects (2005)

It was proved that right ventricular apex pacing (RVAp) deteriorates synchrony of ventricular contraction and decreases cardiac performance. Right ventricular outflow tract pacing (RVOTp) is more favorable pacing option due to better sequence of ventricular activation.
Bicuspid Aortic Valve Is Associated with Less Coronary Calcium and Coronary Artery Disease Burden (2021)

(1) Background. Bicuspid aortic valve (BAV) is associated with genetic defects (NOTCH 1, GATA 5) and aortopathy. Differences in the flow patterns and a genetic predisposition could also affect coronary arteries. The objective was to assess the coronary artery calcium score (CACS) and coronary artery disease (CAD) burden by coronary computed tomography angiography (CTA) in patients with BAV stenosis, as compared to stenotic tricuspid aortic valves (TAV). (2) Methods. A retrospective case-control study. A total of 47 patients with BAV stenosis (68.9 years ± 12.9, 38.3% females) who underwent CTA were matched with 47 TAV stenosis patients for age, gender, smoking, arterial hypertension, dyslipidemia, diabetes, body-mass-index and chronic kidney disease. (3) Results. The coronary artery calcium score (CACS) was lower in BAV (237.4 vs. 1013.3AU; <i>p</i> < 0.001) than in TAV, and stenosis severity was less (CAD-RAD<sup>TM</sup>: <i>p</i> < 0.001). More patients with BAV had CACS zero (27.7% vs. 0%; <i>p</i> < 0.001). The majority (68.1%) of patients with BAV had no or non-obstructive CAD but only 25.5% of TAV (<i>p</i> < 0.001). Obstructive CAD (>50% stenosis) by CTA was more frequently observed in patients with TAV (68.1%; <i>p</i> < 0.001). (4) Conclusions and Relevance. Patients with BAV stenosis have markedly less coronary calcium and less severe coronary stenosis. CTA succeeds to rule out obstructive CAD in the majority of BAV, with adherent implications for TAVR planning.

RENAL GUNSHOT WOUNDS (1993)

Over the past 14 years, 2079 patients have been seen at our institution with renal trauma. Of these, 84 sustained gunshot wounds (81 unilateral, 3 bilateral; a total of 87 renal units). We evaluated this group to characterize the nature of their injuries and establish a methodology for renal salvage and reconstruction. Preoperative radiographic staging was performed with excretory urography (IVP) or computed tomographic (CT) scanning. The injuries were classified into five categories: 16 contusions (18.4%), 12 minor lacerations (13.8%), 44 major lacerations (50.5%), six vascular injuries (6.9%), and nine combination laceration and vascular injury (10.3%). Most patients had multiple organ injuries, with 79 requiring associated surgical procedures (94%). The mean Injury Severity Score (ISS) was 26.7 (range, 4–59). Based on radiographic and clinical staging criteria, 69 renal injuries were surgically explored (79.3%), and 12 patients underwent nephrectomy (13.8%). Forty-six renal units were reconstructed (66.6%) by various methods, including renorrhaphy, omental pedical flaps, mesh or peritoneal patch grafts, partial nephrectomy, and vascular repair. Overall, 75 renal units were salvaged (86.2%). Early renal vascular control was achieved in all patients who underwent renal exploration. Follow-up functional studies were done in 24 (28.5%): none had delayed nephrectomy or postinjury hypertension. Overall, 79 patients survived (94%); however, mortality was not related to renal injury. These findings suggest that aggressive radiographic staging coupled with early vascular control and careful selection of reconstructive techniques can ensure a high renal salvage rate in patients with renal gunshot injuries.
A Design-for-Debug (DfD) for NoC-Based SoC Debugging via NoC (2008)

This paper presents design-for-debug (DfD) methods for the reuse of network-on-chip (NoC) as a debug data path in an NoC-based system-on-chip (SoC). We propose on-chip core debug supporting logics which can support transaction-based debug. A debug interface unit is also presented to enable debug data transfer through an NoC between an external debugger and a core-under-debug (CUD). The proposed approach supports debug of designs with multiple clock domains. It also supports collection of trace signatures to facilitate debug of long pattern sequences. Experimental results show that single and multiple stepping through transactions are feasible with moderately low area overhead. We also present simulation result to verify proper operation of the debug components.
Rational decision making in a wide scenario of different minimally invasive lumbar interbody fusion approaches and devices (2018)

With the proliferation of a variety of modern MIS spine surgery procedures, it is mandatory that the surgeon dominate all aspects involved in surgical indication. The information related to the decision making in patient selection for specific procedures is mandatory for surgical success. The objective of this study is to present decision-making criteria in minimally invasive surgery (MIS) selection for a variety of patients and pathologies. In this article, practicing surgeons who specialize in various MIS approaches for spinal fusion were engaged to provide expert opinion and literature review on decision making criteria for several MIS procedures. Pros, cons, relative limitations, and case examples are provided for patient selection in treatment with MIS posterolateral fusion (MIS-PLF), mini anterior lumbar interbody fusion (mini-ALIF), lateral interbody fusion (LLIF), MIS posterior lumbar interbody fusion (MIS-PLIF) and MIS transforaminal lumbar interbody fusion (MIS-TLIF). There is a variety of aspects to consider when deciding which modern MIS surgical approach is most appropriate to use based on patient and pathologic characteristics. The surgeon must adapt them to the characteristic of each type of patients, helping them to choose the most effective and efficient therapeutic option for each case.
Overview Of Fiber Optic Research At Brown University (1990)

Research in the Laboratory for Lightwave Technology is focused on novel applications of specially designed optical fibers. Emphasis is placed on new techniques of dopant incorporation, using both MCVD (Modified Chemical Vapor Deposition) and OVD (Outside Vapor Deposition) to fabricate fibers that are primarily for non-telecommunications applications. The topics pursued are fibers for fiber lasers, nonlinear effects in fibers, in particular, second harmonic generation, fiber devices for the measurement of electric field, new techniques for the fabrication of bulk-glass gradient index lenses, fiber designs for embedded fibers for sensor elements of future &quot;smart skin&quot; composites, the poling of glasses to induce anisotropy or possibly optical activity, and finally, fiber designs for N x N fused taper couplers.
File and object replication in data grids (2002)

Data replication is a key issue in a data grid and can be managed in different ways and at different levels of granularity: for example, at the file level or the object level. In the high-energy physics community, data grids are being developed to support the distributed analysis of experimental data. We have produced a prototype data replication tool, the Grid Data Management Pilot (GDMP) that is in production use in one physics experiment, with middleware provided by the Globus toolkit used for authentication, data movement and other purposes. We present a new, enhanced GDMP architecture and prototype implementation that uses Globus data-grid tools for efficient file replication. We also explain how this architecture can address object replication issues in an object-oriented database management system. File transfer over wide-area networks requires specific performance tuning in order to gain optimal data transfer rates. We present performance results obtained with GridFTP, an enhanced version of FTP, and discuss tuning parameters.
Extended Algorithm of Servodrive Mechanical Parameters Identification via Frequency Response Analysis (2020)

Velocity or Position control loop Bode diagrams of servo drives are commonly used to identify the load inertia and mechanical resonances. Apart from these parameters the Bode diagrams contain the information on the total delay time of the loop. The study considers identification of this delay, the value being highly important for tuning procedures of servo-drives. Total delay time is not easy to calculate analytically as it requires knowing precise values of all particular delays in the loop. In the paper, a robust algorithm for position control loop identification considering possible two-mass structure is proposed. Theoretical evaluations are proved by the simulation and experimental results obtained from a several servo drives with different structures of position feedback circuit.
Comparison of bend loss in terahertz waveguide and optical fiber (2007)

This work draws an analogy between optical fibers and Sommerfeld wires because of their similar geometries. The weak guidance approximation for single-mode fibers is also shown to apply to Sommerfeld wires. Results pertaining to bending loss in optical fiber are adapted and applied to Sommerfeld wires, predicting a method by which bending loss in Sommerfeld wires could be reduced.

A Novel Thermal Spectrum Analysis Method for Reliability Analysis of Semiconductor Devices (2007)

As a new concept and method, thermal spectrum analysis, is introduced to characterize non-uniform property of junction temperature distribution in this paper. Unlike common infrared image, the proposed thermal spectrum analysis aims at the active region of power devices and provides a quantificational analysis method to effectively investigate thermotics reliability. Both the thermal spectrum curves and the one-dimension temperature distribution curves are given via quantitative and qualitative analysis base on infrared images. The one-dimension temperature distribution curve brings the high readability and convenience for characterizing uniform property and calculating non-uniform degree. The junction temperature distribution of the active region of power devices, peak junction temperature and minimum junction temperature are given in the proposed method. The average junction temperature is calculated through the one-dimension temperature distribution curves. The proposed thermal spectrum analysis, as a new concept, has inducted a novel approach of analyzing temperature distribution of devices. Moreover, the thermal spectrum proposed in this paper will induct a new approach of detecting temperature distribution via complete electrical method, and will create significant impact for the reliability analysis of semiconductor devices.

Structural changes of protein antigens due to adsorption onto and release from aluminium hydroxide using FTIR–ATR (2007)

Structural integrity of antigens upon adsorption and release is not only important for investigating vaccine immunogenicity, but also for the epitope specificity of the resulting immune response and hence therapeutic efficacy. Moreover, the structural information is also important for understanding the mechanism of how adjuvants can enhance the immune response. However, little is known about an antigen′s structure when it is adsorbed on and subsequently released from aluminium adjuvants. In this study, the structures of two protein antigens, bovine serum albumin and β‐lactoglobulin, were investigated using Fourier transform infrared–attenuated total reflection (FTIR–ATR) spectroscopy. The secondary structures of both model antigens change when adsorbed to aluminium hydroxide. The structural perturbation depends on the amount of adsorbed protein. Maximal adsorption gives a more native‐like structure. This may indicate that protein is adsorbed in different manners depending on the concentration. The adsorbed antigens are released using phosphate buffer pH 7.4 (PB). The recovery is approximate 80% after 40 min in the presence of PB. The recovery curves of both proteins also indicate two different adsorption modes. FTIR–ATR and circular dichroism (CD) spectroscopy yield similar results suggesting that the adsorbed antigens refold to their native‐like state after release.

2‐DE and MS analysis of interactions between Lactobacillus fermentum I5007 and intestinal epithelial cells (2007)

Lactobacillus is a probiotic commonly used for supplementation to human and animal diets. In this study, we used 2-DE and MS to analyze changes in the proteomes of Lactobacillus and intestinal epithelial cells in two model systems. The in vivo and in vitro models were involved the inoculation of Lactobacillus fermentum I5007 into the rabbit jejunum for 4 h and the culture of the bacterium with Caco-2 cells for 1 h, respectively. Our results indicate that, after exposure to the intestinal environment, the bacterium exhibited decreases in key enzymes involved in energy metabolism (e.g., lactate dehydrogenase, dihydrolipoamide dehydrogenase, and nicotinate phosphoribosyltransferase) and amino acid metabolism (e.g., arginyl-tRNA synthetase and aspartate-semialdehyde dehydrogenase), but increases in glycoside hydrolase (an enzyme for mucin degradation) and fructose-6-phosphate phosphoketolase (an enzyme of the pentose phosphate pathway). In response to an interaction with L. fermentum I5007, Caco-2 cells showed changes in proteins that were beneficial for gut integrity, including voltage-dependent anion channel 1, glutathione transferase, and heat shock protein gp96. On the basis of their functions, we suggest that these proteins serve as useful biomarkers for metabolic changes in Lactobacillus and intestinal epithelial cells in response to their interactions.
