A 3D Shape Descriptor Based on Depth Complexity and Thickness Histograms (2015)

Geometric models play a vital role in several fields, from the entertainment industry to scientific applications. To reduce the high cost of model creation, reusing existing models is the solution of choice. Model reuse is supported by content-based shape retrieval (CBR) techniques that help finding the desired models in massive repositories, many publicly available on the Internet. Key to efficient and effective CBR techniques are shape descriptors that accurately capture the characteristics of a shape and can discriminate between different shapes. We present a descriptor based on the distribution of two global features measured in a 3D shape, depth complexity and thickness, which respectively capture aspects of the geometry and topology of 3D shapes. The final descriptor, called DCTH (depth complexity and thickness histogram), is a 2D histogram that is invariant to the translation, rotation and scale of geometric shapes. We efficiently implement the DCTH on the GPU, allowing its use in real-time queries of large model databases. We validate the DCTH with the Princeton and Toyohashi Shape Benchmarks, containing 1815 and 10000 models respectively. Results show that DCTH can discriminate meaningful classes of these benchmarks and is fast to compute and robust against shape transformations and different levels of subdivision and smoothness.
Selective serotonin reuptake inhibitors cause erectile dysfunction: true or false? (2009)

The Effects of Citalopram and Fluoxetine on Sexual Behavior in Healthy Men: Evidence of Delayed Ejaculation and Unaffected Sexual Desire. A Randomized, Placebo-Controlled, Double-Blind, Double-Dummy, Parallel Group Study

Madeo B, Bettica P, Milleri S, et al.

J Sex Med 2008;5:2431–2441.2441 [PubMed]

One of the dilemmas that sexual medicine doctors face is that many of their male patients have depression and are being treated with antidepressive medications, specifically selective serotonin reuptake inhibitors (SSRIs). SSRIs are known to cause delayed ejaculatory responses, but many of these patients also complain of erectile dysfunction (ED). Because depression and erectile dysfunction seem to go hand-in-hand for many patients, many practitioners believe both from their anecdotal experience and what is written in the literature that SSRIs can affect erectile function in addition to its well-known effect on ejaculatory function.

To help unravel the mystery of whether the SSRIs cause ED, Madeo and colleagues performed a double-blind, randomized, placebo-controlled study comparing 2 SSRIs (citalopram and fluoxetine) with placebo. The patients were normal, healthy volunteers (n = 16 for each group). The treatment lasted 4 weeks. Outcomes were ejaculatory function, erectile function measured by the International Index of Erectile Function questionnaire and RigiScan? (Timm Medical Technologies, Eden Prairie, MN) assessment following visual erotic stimuli. The authors demonstrated in this elegant study that both SSRIs caused delayed ejaculatory function compared with placebo, but there was no impact on erectile function in these normal male volunteers.

The results of this study demonstrate that SSRIs do not affect erectile function and the cause of the ED in patients on these drugs must be primarily due to another etiology.

Structures and Materials in Stretchable Electroluminescent Devices (2021)

Stretchable electroluminescent (EL) devices are obtained by partitioning a large emission area into areas specifically for stretching and light-emission (island-bridge structure). Buckled and textile structures are also shown effective to combine the conventional light emitting diode fabrication with elastic substrates for structure-enabled stretchable EL devices. Meanwhile, intrinsically stretchable EL devices which are characterized with uniform stretchability down to microscopic scale are relatively less developed but promise simpler device structure and higher impact resistance. The challenges in fabricating intrinsically stretchable EL devices with high and robust performance are in many facets, including stretchable conductors, emissive materials, and compatible processes. For the stretchable transparent electrode, ionically conductive gel, conductive polymer coating, and conductor network in surface of elastomer are all proven useful. The stretchable EL materials are currently limited to conjugated polymers, conjugated polymers with surfactants and ionic conductors added to boost stretchability, and phosphor particles embedded in elastomer matrices. These emissive materials operate under different mechanisms, require different electrode materials and fabrication processes, and the corresponding EL devices face distinctive challenges. This review aims to provide a basic understanding of the materials meeting both the mechanical and electronic requirements and important techniques to fabricate the stretchable EL devices.
Deformation of a Sheet with Coupling between Elasticity and Concentration (2007)

We investigate a simple model for equilibrium deformation of a sheet with concentration-dependent elasticity. The model is motivated by several physical situations where deformation of a sheet is modulated by concentration of a mobile species, for example, a quasi-2D array of carbon nanotubes. Elasticity of the sheet is modeled using a free energy functional that includes concentration-dependent potential energies, and a free energy of mixing. We show that the sheet responds to imposed distortion by rearranging its constituents and can do so in a smooth and stable manner only for sufficiently small distortion. For larger distortions, through phase plane and numerical analysis, we consider how the system can meet boundary conditions through nonsmooth solutions.
Characterization of Tribological Properties of Greases for Industrial Circuit Breakers (2017)

Proper grease selection is essential for the electrical industry to minimize friction and wear between the components of circuit breakers under mechanical contact. In this investigation, the tribological properties of commercially available greases for industrial circuit breakers were evaluated. Three tribological tests were performed: the ITeE-PIB Polish Method for testing lubricants under scuffing conditions (extreme pressure, EP), a four-ball test under ASTM D 2266 (anti-wear, AW), and a ball-ondisk test based on ASTM G-99. The worn materials were characterized with an optical 3D profilometer measurement system and a scanning electron microscope (SEM). Additionally, selected greases with the best tribological performance were tested on a testing bench intended for circuit breakers, according to electrical safety standards, which validated the results obtained in the laboratory.
Small array antenna for 2x2 MIMO terminal using folded loop antenna (2006)

Recently, MIMO technologies for mobile phones have been investigated to achieve high-speed data communication. It is preferable to have a smaller and more efficient antenna system for the MIMO terminal. Although built-in antennas are more convenient, coupling between antennas and the human body is larger than with extended antennas. So far, for the built-in elements, we have proposed a folded loop antenna (FLA) with balanced feed and a parallel plane antenna (PPA) with unbalanced feed. Because of the smaller human effects, these antennas may work effectively as MIMO antenna arrays. In this paper, 3 types of 2times2 MIMO antenna are investigated to show the effectiveness of the built-in antenna array for the terminal in a multi-pass wave environment. The channel capacity is employed to estimate the antenna performance.
Joint Graph Decomposition and Node Labeling: Problem, Algorithms,\n Applications (2016)

We state a combinatorial optimization problem whose feasible solutions define\nboth a decomposition and a node labeling of a given graph. This problem offers\na common mathematical abstraction of seemingly unrelated computer vision tasks,\nincluding instance-separating semantic segmentation, articulated human body\npose estimation and multiple object tracking. Conceptually, the problem we\nstate generalizes the unconstrained integer quadratic program and the minimum\ncost lifted multicut problem, both of which are NP-hard. In order to find\nfeasible solutions efficiently, we define two local search algorithms that\nconverge monotonously to a local optimum, offering a feasible solution at any\ntime. To demonstrate their effectiveness in tackling computer vision tasks, we\napply these algorithms to instances of the problem that we construct from\npublished data, using published algorithms. We report state-of-the-art\napplication-specific accuracy for the three above-mentioned applications.\n

Effect of yeast inoculation rate on the metabolism of contaminating lactobacilli during fermentation of corn mash (2004)

Two separate 4 (bacterial concentrations)x6 (yeast concentrations) full factorial experiments were conducted in an attempt to identify a novel approach to minimize the effects caused by bacterial contamination during industrial production of ethanol from corn. Lactobacillus plantarum and Lactobacillus paracasei, commonly occurring bacterial contaminants in ethanol plants, were used in separate fermentation experiments conducted in duplicate using an industrial strain of Saccharomyces cerevisiae, Allyeast Superstart. Bacterial concentrations were 0, 1x10(6), 1x10(7) and 1x10(8) cells/ml mash. Yeast concentrations were 0, 1x10(6), 1x10(7), 2x10(7), 3x10(7), and 4x10(7) cells/ml mash. An increased yeast inoculation rate of 3x10(7) cells/ml resulted in a greater than 80% decrease (P < 0.001) and a greater than 55% decrease (P < 0.001) in lactic acid production by L. plantarum and L. paracasei, respectively, when mash was infected with 1x10(8) lactobacilli/ml. No differences (P > 0.25) were observed in the final ethanol concentration produced by yeast at any of the inoculation rates studied, in the absence of lactobacilli. However, when the mash was infected with 1x10(7) or 1x10(8) lactobacilli/ml, a reduction of 0.7-0.9% v/v (P < 0.005) and a reduction of 0.4-0.6% v/v (P < 0.005) in the final ethanol produced was observed in mashes inoculated with 1x10(6) and 1x10(7) yeast cells/ml, respectively. At higher yeast inoculation rates of 3x10(7) or 4x10(7) cells/ml, no differences (P > 0.35) were observed in the final ethanol produced even when the mash was infected with 1x10(8) lactobacilli/ml. The increase in ethanol corresponded to the reduction in lactic acid production by lactobacilli. This suggests that using an inoculation rate of 3x10(7) yeast cells/ml reduces the growth and metabolism of contaminating lactic bacteria significantly, which results in reduced lactic acid production and a concomitant increase in ethanol production by yeast.

Effects of Spontaneous and Simulated Gastroesophageal Reflux on Sleeping Asthmatics (1990)

We examined the effect of intraesophageal acid (either spontaneous gastroesophageal reflux or infused) on airflow resistance in 15 sleeping asthmatic subjects. We observed no significant acute or sustained changes in airflow resistance relative to periods of intraesophageal acid. Overnight changes in spirometry and lower airway resistance also demonstrated similar nocturnal worsening of bronchoconstriction despite the occurrence of spontaneous or simulated gastroesophageal reflux. The presence or absence of clinical evidence of esophagitis (Bernstein test response) did not alter the observed lack of response to intraesophageal acid. We conclude that gastroesophageal reflux contributes little to the nocturnal worsening of asthma.
Influence of basketball shoe mass, outsole traction, and forefoot bending stiffness on three athletic movements (2015)

Prior research has shown that footwear can enhance athletic performance. However, public information is not available on what basketball shoe properties should be selected to maximise movement performance. Therefore, the purpose of the study was to investigate the influence of basketball shoe mass, outsole traction, and forefoot bending stiffness on sprinting, jumping, and cutting performance. Each of these three basketball shoe properties was systematically varied by ± 20% to produce three shoe conditions of varying mass, three conditions of varying traction, and three conditions of varying bending stiffness. Each shoe was tested by 20 recreational basketball players completing maximal effort sprints, vertical jumps, and a cutting drill. Outsole traction had the largest influence on performance, as the participants performed significantly worse in all tests when traction was decreased by 20% (p < 0.001), and performed significantly better in the cutting drill when traction was increased by 20% (p = 0.005). Forefoot bending stiffness had a moderate effect on sprint and cutting performance (p = 0.013 and p = 0.016 respectively) and shoe mass was found to have no effect on performance. Therefore, choosing a shoe with relatively high outsole traction and forefoot bending stiffness should be prioritised, and less concern should be focused on selecting the lightest shoe.
RAS Modeling of a Large InfiniBand Switch System (2009)

Computer clusters or grids constructed from open and standard commercial off the shelf (COTS) systems now dominate the top 500 supercomputer sites (Top500, 2008), providing an attractive way to rapidly construct high performance computing (HPC) systems of interconnected nodes. The largest of these HPC systems are now driving toward petascale deployments, delivering petaflops of computational capacity and petabytes of storage capacity. However, designing and building these large HPC systems involves significant challenges, including:
THE RATIO OF THE QUASI-ELASTIC TO THE ELASTIC CHARGE-EXCHANGE-PROCESS YIELDS AT THE PROTON EMITTING ANGLE OVER 0.552.0-GEV NEUTRON-BEAM ENERGY REGION. EXPERIMENTAL RESULTS (2009)

New experimental results on ratio of the quasi-elastic charge-exchange yield at the outgoing proton angle for the reaction to the elastic charge-exchange yield, are presented. The measurements were carried out at the Nuclotron of the Veksler and Baldin Laboratory of High Energies of the JINR (Dubna) at the neutron-beam kinetic energies of 0.55, 0.8, 1.0, 1.2, 1.4, 1.8, and 2.0 GeV. The intense neutron beam with small momentum spread was produced by breakup of deuterons which were accelerated and extracted to the experimental hall. In both reactions mentioned above the outgoing protons with the momenta approximately equal to the neutron-beam momentum were detected in the directions close to the direction of incident neutrons, i.e., in the vicinity of the scattering angle . Measured in the same data-taking runs, the angular distributions of the charge-exchange-reaction products were corrected for the well-known instrumental effects and averaged in the vicinity of the incident-neutron-beam direction. These corrected angular distributions for every of and charge-exchange processes were proportional to the differential cross sections of the corresponding reactions. The data were accumulated by DeltaSigma setup magnetic spectrometer with two sets of multiwire proportional chambers located upstream and downstream of the momentum analyzing magnet. Inelastic processes were considerably reduced by the additional detectors surrounding the hydrogen and deuterium targets. The time-of-flight system was applied to identify the detected particles. The accumulated data treatment and analysis, as well as possible sources of the systematic errors are discussed.
A new strategy for the metal template synthesis of organic metal ion cages (1990)

High yield template syntheses of hexa-azabicycloeicosanes and related imines are described arising from non-aqueous condensations of mixed aldehydes with the 4,4′,4″-ethylidyne-tris(3-azabutan-1-amine)cobalt(III) ion in basic media.
[Dual x-ray absorptiometry assessment of bone density of the proximal tibia in advanced-stage degenerative disease of the knee]. (2001)

DXA assessment of bone mineral density of the proximal tibia is a simple, reliable, precise and reproducible method. The distribution of bone density in the degenerative knee depends on the degree of deformation. The average level depends on the subject's general state of mineralization. Osteoporosis does not protect against degeneration of the knee joint since 16 p. 100 of our patients had osteoporosis according to the WHO criteria.
The Effect of Power Allocation on Visible Light Communication Using Commercial Phosphor-Converted Led Lamp for Indirect Illumination (2020)

Visible light communication (VLC) systems should be designed to provide illumination and wireless data services simultaneously. To achieve this goal at a reasonable cost, the use of Phosphor-Converted (PC) LEDs for indirect illumination should be favored to provide a homogeneous and reliable coverage in the whole service area. Unfortunately, PC-LEDs found in the market so far have not been designed for data transmission; moreover, the response of the other (electro-) optical components of the VLC link are far from ideal. In this paper, we estimate the data rate that is feasible with VLC when indirect illumination is used. For this purpose, the end-to-end response of the VLC link is first modeled using actual measurements of the spectral power distribution of a PC-LED lamp and the ceiling reflectance. Then, different power allocation schemes are studied assuming an optical OFDM waveform. As commercial LEDs have a relatively slow time response, the equivalent VLC channel that results has strong frequency selectivity; therefore, notable data rate gains are achievable when waterfilling power allocation is applied.

Hands On Projects And Exercises To Strengthen Understanding Of Basic Computer Engineering Concepts (2020)

The Introduction to Computer Engineering course at the University of Missouri-Rolla provides a thorough understanding of basic digital logic analysis and design. The course covers: digital numbering systems, Boolean algebra, function minimization using Karnaugh maps (K-maps), memory elements, and sequential logic design. Students' grades are determined by their performance on homework assignments, quizzes, and in-class examinations. A laboratory course (optional for all but EE and CpE majors) supplements the lecture by providing experiments that include analysis and design using Mentor Graphics and FPGAs. While the laboratory is a very useful supplement to the lecture, almost half the students taking the lecture are not required to take the laboratory and there is not sufficient time in the laboratory schedule to introduce significant design elements. In Fall 2004, hands-on group projects, for all students, were introduced to the lecture course. The goal was for students to develop a more practical understanding and appreciation of hardware design and to improve motivation. Two projects were introduced that involve design of simple digital systems (based on practical applications), design optimization, and physical realization of the system using logic gates and/or memory elements. Two surveys, conducted during the semester, show the benefit of hands-on projects in gaining experience on basic digital hardware design.
