A parallel true motion estimation method based on binarized cross correlation (2014)

Block based recursive search for motion estimation is already suitable for real time applications thanks to its wide utilization, but the increase of resolution in modern displays and the need for real time software implementations demand for faster approaches. In this paper a new motion estimation procedure that has been developed for a parallel implementation is presented. The parallel implementation was achieved by avoiding the spatial recursion which is typical for the recursive search systems, while the convergence can still be obtained by means of the temporal recursion only. In particular the use of a binarized cross correlation as a matching cost criteria instead of the standard SAD permits an improved motion vector field and a faster convergence without increasing the computational cost. The experimental results show a similar vector field estimation in comparison to the standard SAD based recursive search method with the considerable advantage of a possible parallel implementation.

Comparison of Muscle Recovery Following Bi-cruciate Substituting versus Posterior Stabilized Total Knee Arthroplasty in the Asian Population (2017)

Abstract The purpose of this study was to compare muscle recovery in the lower extremities following the newly developed bi-cruciate substituting (BCS) to posterior stabilized (PS) total knee arthroplasty (TKA) in the Asian population. Forty-one knees in 41 patients undergoing BCS-TKA (41 female, average age: 71 ± 8.8) and 34 knees in 34 patients undergoing PS-TKA (33 female, average age: 73 ± 7.2) were included in this study. The maximum isometric power of the quadriceps and hamstring muscles was measured preoperatively, and at 1, 3, 6, and 12 months after surgery using a handheld dynamometer. Postoperative muscle recovery was calculated regarding preoperative muscle power as 100%. Pre- and postoperative range of knee motion, femorotibial angle, and clinical scores (Knee Society score and function score) were also compared. No significant difference in sex, age, preoperative quadriceps, or preoperative hamstring power was observed between the BCS and PS-TKA groups. When regarding the preoperative muscle power as 100%, quadriceps power at 1, 3, 6, and 12 months following BCS-TKA was 61.2 ± 22%, 86.3 ± 28.3%, 97 ± 27.4%, and 112.4 ± 30.8%, respectively. Quadriceps power at 1, 3, 6, and 12 months following PS-TKA was 72.4 ± 20.8%, 84 ± 16.9%, 95 ± 20.7%, and 110.8 ± 27%, respectively. Hamstring power at 1, 3, 6, and 12 months following BCS-TKA was 96.3 ± 30%, 111.4 ± 35%, 120 ± 37%, and 125 ± 31%, respectively. Hamstring power at 1, 3, 6, and 12 months following PS-TKA was 95 ± 25%, 112.4 ± 27%, 117 ± 38.5%, and 120.4 ± 18.5%, respectively. No significant difference in muscle power recovery was observed at 3 (p = 0.995), 6 (p = 0.944), and 12 (p = 0.917) months after surgery between the two groups. No significant difference of the clinical score was observed between the groups (Knee Society score: p = 0.479, function score: p = 0.342). No significant difference in muscle recovery and clinical score were observed between the BCS and PS-TKA groups. Longer follow-up is needed for the evaluation of efficacy of BCS-TKA in the Asian populations.
Antioxidant, Anti-inflammatory, and Antiproliferative Activity of Mori Cortex Radicis Extracts (2020)

Mori Cortex Radicis (MCR) is a well-known Korean and Chinese folk medicine with anti-obesity, anti-inflammatory, anti-asthmatic, and hypoglycemic activities. This study was aimed to evaluate the total phenolic and flavonoid contents, as well as intracellular antioxidant and anti-inflammatory effects of water and 70% (v/v) ethanol extracts of MCR. The antioxidant activities of MCR extracts were determined with diphenyl-2-picrylhydrazyl and 2,2′-azinobis[3-ethylbenzothiazoline-6-sulfonic] scavenging activity assays. The suppressive activities of MCR extracts on the production of nitric oxide (NO * ) and the expression of cytokines, c-Fos, activated p38-Mitogen-activated protein kinase (MAPK), and Nuclear factor Kappa B (NF-κB) and splenocytes proliferation in lipopolysaccharide-treated macrophages were determined. Furthermore, this study demonstrated the effects of MCR on reactive oxygen species production in murine macrophages. Mori Cortex Radicis restored deoxyribonucleic acid damages at higher concentrations of the extracts and significantly suppressed free radicals and NO * production. In this study, MCR significantly restored inflammatory responses and intracellular antioxidant activities in murine macrophages (RAW 264.7), which anticipated that MCR could be used as a natural anti-inflammatory agent.

Blood Pressure-Lowering Peptides from Neo-Fermented Buckwheat Sprouts: A New Approach to Estimating ACE-Inhibitory Activity (2014)

Neo-fermented buckwheat sprouts (neo-FBS) contain angiotensin-converting enzyme (ACE) inhibitors and vasodilators with blood pressure-lowering (BPL) properties in spontaneously hypertensive rats (SHRs). In this study, we investigated antihypertensive mechanisms of six BPL peptides isolated from neo-FBS (FBPs) by a vasorelaxation assay and conventional in vitro, in vivo, and a new ex vivo ACE inhibitory assays. Some FBPs demonstrated moderate endothelium-dependent vasorelaxation in SHR thoracic aorta and all FBPs mildly inhibited ACE in vitro. Orally administered FBPs strongly inhibited ACE in SHR tissues. To investigate detailed ACE-inhibitory mechanism of FBPs in living body tissues, we performed the ex vivo assay by using endothelium-denuded thoracic aorta rings isolated from SHRs, which demonstrated that FBPs at low concentration effectively inhibited ACE in thoracic aorta tissue and suppressed angiotensin II-mediated vasoconstriction directly associated with BPL. These results indicate that the main BPL mechanism of FBP was ACE inhibition in living body tissues, suggesting that high FBP's bioavailability including absorption, tissue affinity, and tissue accumulation was responsible for the superior ACE inhibition in vivo. We propose that our ex vivo assay is an efficient and reliable method for evaluating ACE-inhibitory mechanism responsible for BPL activity in vivo.
Probabilistic Back-ends for Online Speaker Recognition and Clustering (2023)

This paper focuses on multi-enrollment speaker recognition which naturally occurs in the task of online speaker clustering, and studies the properties of different scoring back-ends in this scenario. First, we show that popular cosine scoring suffers from poor score calibration with a varying number of enrollment utterances. Second, we propose a simple replacement for cosine scoring based on an extremely constrained version of probabilistic linear discriminant analysis (PLDA). The proposed model improves over the cosine scoring for multi-enrollment recognition while keeping the same performance in the case of one-to-one comparisons. Finally, we consider an online speaker clustering task where each step naturally involves multi-enrollment recognition. We propose an online clustering algorithm allowing us to take benefits from the PLDA model such as the ability to handle uncertainty and better score calibration. Our experiments demonstrate the effectiveness of the proposed algorithm.

The rationale behind this Project is the need to implement an electronic device for the simulation of antennas used in the military tactical radios P/PRC525 in different operation scenarios.
Neutral fluorescence probe with strong ratiometric response to surface charge of phospholipid membranes (2001)

We report on dramatic differences in fluorescence spectra of 4'-dimethylamino-3-hydroxyflavone (probe F) studied in phospholipid membranes of different charge (phosphatidyl glycerol, phosphatidylcholine (PC), their mixture and the mixture of PC with a cationic lipid). The effect consists in variations of relative intensities at two well-separated band maxima at 520 and 570 nm belonging to normal (N*) and tautomer (T*) excited states of flavone chromophore. Based on these studies we propose a new approach to measure electrostatic potential at the surface layer of phospholipid membranes, which is based on potential-dependent changes of bilayer hydration and involves very sensitive and convenient ratiometric measurements in fluorescence emission.
Surface-Enhanced Raman Scattering-Active Au/SiO2 Nanocomposites Prepared Using Sonoelectrochemical Pulse Deposition Methods (2012)

For improving signals, reproducibility, and stabilities of surface-enhanced Raman scattering (SERS), numerous technologies have recently been reported in the literature. However, the fabrication processes are usually complicated. It is well-known that nanoparticles (NPs) of Au and SiO(2) are SERS active and inactive materials, respectively. In this work, a simple synthesis route based on sonoelectrochemical pulse deposition (SEPD) methods has been developed to synthesize effectively SERS-active Au/SiO(2) nanocomposites (NCs) with an enhancement factor of 5.4 × 10(8). Experimental results indicate that pH value of solution and addition of SiO(2) NPs before and after oxidation-reduction cycles (ORCs) can significantly influence the corresponding SERS activities. Encouragingly, the SERS of Rhodamine 6G (R6G) adsorbed on the developed Au/SiO(2) NCs exhibits a higher intensity by more than 1 order of magnitude, as compared with that of R6G adsorbed on Au NPs synthesized using the same method. Moreover, this improved SERS activity is successfully verified from the mechanisms of electromagnetic (EM) and chemical (CHEM) enhancements.
Evaluation of Cooking Suitability of Processing Tomato Cultivars for ‘Cooking Tomato’ (2004)

一般家庭でのトマトの加熱調理の実態をふまえ，加工用トマトの加熱調理適性を総合的に評価した． 1．素材が市販の生食用トマトの場合は，ホールトマトの場合に比べ料理の種類が多岐に及んでいた．加熱調理適性としては，加熱後の水気の少なさ（粘稠度）と赤味が重要と考えられた． 2．心止まり性の23品種・系統を対象に，栽培特性，貯蔵特性を比較した結果，疫病の発生が少なく，栽培期間中や貯蔵期間中の腐敗果率が少ない点で‘とよこま’，‘なつのこま’，‘にたきこま’が北日本地域での栽培に適していた．特に‘とよこま’は，多収で一挙収穫率も低く，栽培特性と貯蔵特性において総合的に優れていた． 3．上記3品種のうち，‘なつのこま’と‘にたきこま’は果形が収穫期にかかわらず卵形で，現在一般に流通している生食用品種と区別しやすく，加熱後の粘稠度はいずれの品種も生食用品種より優れていた．加熱後の赤味は‘なつのこま’以外の2品種で生食用品種より強かった．以上の結果から，生食用品種を加熱調理している日本の現状では，これらの品種の導入により，トマトの加熱料理の質の大幅な向上が期待できる． 4．加熱後の粘稠度と果肉部乾物率には負の相関があり，これが今後加熱調理用品種の品種選定や育種素材の選抜のための簡易な評価法として利用できる可能性がある．
STS: Space-time scheduling for coordinating self-organization network functions in LTE (2015)

Self-Organizing Networks (SON) and a number of SO functions (SFs) have been proposed, e.g. in the LTE standard. Since SFs operate on the same network, adjusting the same set of parameters, conflicts arise. Mechanisms are thus required to resolve or minimize these conflicts. We propose Space-Time scheduling procedures that allow for separating the execution of SFs at different space and time points so as to minimize negative cross effects among the SFs. Using two Q-learning based SFs, our results show that the combined scheduling in space and time ensures that SFs learn optimal behaviors that are only due to their own actions and not the peers' actions. In doing so, they maintain good performance even within the shared environment.
Letter: which patient profile for tacrolimus in ulcerative colitis? (2016)

We read with interest the article from Yamamoto et al. comparing oral tacrolimus with infliximab in their retrospective cohort of patients with glucocorticosteroid-refractory ulcerative colitis (UC).1 Their experience confirms two positive placebo-controlled trials and retrospective series showing that tacrolimus could be an alternative in this situation, as recommended by ECCO guidelines.2-5 Like ciclosporin, tacrolimus is a calcineurin inhibitor with good efficacy and safety profiles in UC. Moreover, and similar to ciclosporin, Yamamoto et al. have given tacrolimus as a 12-week bridging therapy to azathioprine, and then discontinued the drug. Patient selection is crucial point for determining if oral tacrolimus should be used instead of ciclosporin in UC. Two different subsets of patient with glucocorticosteroid-refractory disease may receive ciclosporin: those admitted with an acute severe attack, not responding after a few days of intravenous glucocorticosteroids and requiring parenteral second-line medical therapy as an alternative to salvage colectomy; and, those with a non-acute severe flare who could be treated orally and managed as an out-patient. In the first situation, Truelove and Witts criteria are still recommended for identifying patients with a severe attack of UC, and the Lichtiger index is a valuable tool for assessing those refractory to intravenous glucocorticosteroids.5, 6 Unfortunately, Yamamoto et al. pooled those with an acute severe attack and a moderate exacerbation in their cohort, using the UC disease activity index (UC-DAI) as an inclusion criterion. The UC-DAI was developed 30 years ago in a study exploring salicylates enema in distal UC7 and has been used as a selection and judgment criteria in controlled trials evaluating tacrolimus in refractory UC.4 However, and as stated above, it is definitely not appropriate in this population. Moreover, as Yamamoto et al. did not provide the rate of patients with intravenous glucocorticosteroid failure at inclusion, the proportion of patients with acute severe UC in their cohort remains impossible to assess. Therefore, the best patient profile for oral tacrolimus in UC remains unclear. Pending studies confirming tacrolimus efficacy in patients with acute severe UC, defined according to more usual criteria, physicians have only two validated medical options after glucocorticosteroid failure, which are ciclosporin and infliximab. Importantly, none of the others biologics available in UC, such as subcutaneous anti-tumour necrosis factor or anti-integrin monoclonal antibodies, have been evaluated in this special setting corresponding to an exclusion criteria from pivotal phase III studies.

A New and Improved Synthesis of N-Butyl-1 -Deoxynojirimycin (2020)

The preparations of 1-deoxynojirimycin and N-substituted derivatives have long been of interest to the organic chemist. A literature search reveals that these compounds can be made by appropriately protecting the amino group of aminosorbitols, followed by selective microbial oxidation to give isolable 6-aminosorboses. The protecting groups can subsequently be removed either by catalytic hydrogenation or acidification followed by reductive intramolecular ring closure to form 1-deoxynojirimycin or its N-substituted derivatives. The available literature indicates that D-glucose and other sugars react with alkyl amines to give TV-alkylglucosides. It also reports that as a general class these compounds are labile and undergo rearrangement as well as hydrolysis. In addition to an improved synthesis of N-butylglucamine, we have outlined a three-step process for the conversion of D-glucose to N-butyl-l-deoxy-nojirimycin. The entire process is amenable to large-scale production with the following specific improvements.
A Novel Method for Rapid Non Destructive Determination of O/W Creams Stability (1982)

A nonconventional method for evaluation of emulsion stability was developed. The method was found to be valid for viscous emulsions and results obtained are in good correlation to conventional methods compared.The technique is based on electrical conductivity measurements during nondestructive short heating-cooling-heating cycles carried out on cosmetic viscous emulsions. Conductivity curves were obtained on a recorder, where the second heating cycles were lower and almost parallel to the first heating curves. The bigger the conductivity differences between the two heating curves, the lower is the emulsion stability.A relative Stability Index Δ/h, indicating relative change in conductivity between two cycles was elaborated. This index was usefull in finding out- optimal required HLB values for required emulsion- optimal amount of oily phase- emulsifier concentration.
Aspectos esenciales de los sistemas robóticos urológicos (2007)

The oft-repeated argument about whether or not a robot might ever replace the surgeon now has little sense because today it is merely a tool, an instrument for the surgeon's hands. The devices available today lack the all-important tactile feedback and to use them effectively, the surgeon is obliged to serve a new and arduous apprenticeship and the learning curve is unavoidably steep. Consequently, many prestigious authors understandably feel unable to recommend their use. Our accumulated experience with master-slave manipulators stimulates us to confidently predict that sooner than later, whether we like it or not, surgical robots will evolve to become indispensable tools that enhance the surgeon's skill, precision and speed in many surgical procedures.
Object Recognition with Banana Wavelets. (1997)

. We introduce an object recognition system, based on generalized Gabor wavelets, called banana wavelets. In addition to the qualities frequency and orientation, banana wavelets have the attributes curvature and size. Banana wavelets can be metrically organized, a sparse and efficient representation of objects is learned utilizing this metric. 1. Introduction In this paper we describe a novel object recognition system in which representations of object classes can be learned autonomously. The learned representations allow a fast and effective location and identification of objects in complicated scenes. Our object recognition system is based on three pillars. Firstly, our preprocessing is based on the idea of sparse coding [1]. Secondly, effective learning is guided by a priori constraints covering fundamental structure of the visual world. Thirdly, we use Elastic Graph Matching (EGM) [6] for the location and identification of objects. A sparse representation can be defined as a codi...
A Mixed-Integer Linear Programming approach to wind farm layout and inter-array cable routing (2015)

A Mixed-Integer Linear Programming (MILP) approach is proposed to optimize the turbine allocation and inter-array offshore cable routing. The two problems are considered with a two steps strategy, solving the layout problem first and then the cable problem. We give an introduction to both problems and present the MILP models we developed to solve them. To deal with interference in the onshore cases, we propose an adaptation of the standard Jensen's model, suitable for 3D cases. A simple Stochastic Programming variant of our model allows us to consider different wind scenarios in the optimization. For the inter-array cable routing, we propose a new MILP model able to deal with different constraints arsing in practical application, such as capacity limitations, substation limitations and non-crossing constraints. Computational results on real-world instances prove the practical viability of the approach.
Recommendations for the management of postmenopausal vaginal atrophy (2010)

Unlike hot flushes and night sweats which resolve spontaneously in time, atrophic symptoms affecting the vagina and lower urinary tract are often progressive and frequently require treatment. The prevalence of vaginal dryness increases as a woman advances through the postmenopausal years, causing itching, burning and dyspareunia, and sexual activity is often compromised. But, despite the various safe and effective options, only a minority (about 25% in the Western world and probably considerably less in other areas) will seek medical help. Some of this reluctance is due to the adverse publicity for hormone replacement therapy (HRT) over recent years that has suggested an increased risk of breast cancer, heart disease and stroke. But, regardless of whether these scares are justified, local treatment of vaginal atrophy is not associated with these possible risks of systemic HRT. Other reasons for the continued suffering in silence may be cultural and an understandable reluctance to discuss such matters, particularly with a male doctor, but the medical profession must also take much of the blame for failing to enquire of all postmenopausal women about the possibility of vaginal atrophic symptoms. Vaginal dryness can be helped by simple lubricants but the best and most logical treatment for urogenital atrophy is to use local estrogen. This is safe, effective and with few contraindications. It is hoped that these guidelines and recommendations, produced to coincide with World Menopause Day 2010, will help to highlight this major cause of distress and reduced quality of life and will encourage women and their medical advisers all over the world to seek and provide help.
Trajectory reweighting for non-equilibrium steady states (2018)

Modern methods for sampling rugged landscapes in state space mainly rely on knowledge of the relative probabilities of microstates, which is given by the Boltzmann factor for equilibrium systems. In principle, trajectory reweighting provides an elegant way to extend these algorithms to non-equilibrium systems, by numerically calculating the relative weights that can be directly substituted for the Boltzmann factor. We show that trajectory reweighting has many commonalities with Rosenbluth sampling for chain macromolecules, including practical problems which stem from the fact that both are iterated importance sampling schemes: for long trajectories the distribution of trajectory weights becomes very broad and trajectories carrying high weights are infrequently sampled, yet long trajectories are unavoidable in rugged landscapes. For probing the probability landscapes of genetic switches and similar systems, these issues preclude the straightforward use of trajectory reweighting. The analogy to Rosenbluth sampling suggests though that path-ensemble methods such as PERM (pruned-enriched Rosenbluth method) could provide a way forward.
Reductions Of Control Flow Graphs (2014)

Control flow graphs are a well-known representation of<br> the sequential control flow structure of programs with a multitude<br> of applications. Not only single functions but also sets of functions<br> or complete programs can be modeled by control flow graphs. In<br> this case the size of the graphs can grow considerably and thus<br> makes it difficult for software engineers to analyze the control flow.<br> Graph reductions are helpful in this situation. In this paper we define<br> reductions to subsets of nodes. Since executions of programs are<br> represented by paths through the control flow graphs, paths should<br> be preserved. Furthermore, the composition of reductions makes a<br> stepwise analysis approach possible.
