Metal—Semiconductor Barrier Height Measurement by the Differential Capacitance Method—One Carrier System (1963)

The differential capacitance measurement for determining the height of a Schottky barrier at a metal—semiconductor contact is based upon a number of assumptions. In practice, one or more of these assumptions may not be valid. Some of these deviations from the ``ideal case'' are examined in order to determine the effects of each upon the interpretation and validity of measurements on such contacts. Specifically, the effects of each of the following are considered: series resistance, traps in the depletion layer, effective contact area variation with depletion layer width, an insulating interfacial layer between the metal and semiconductor, semiconductor surface charge variation with bias voltage, and the reserve layer at the edge of the barrier. Experimental data for gold plated contacts to conducting cadmium sulfide single crystals are given to illustrate some of the results.
Mechanism of the Coupling of Diazonium to Single‐Walled Carbon Nanotubes and Its Consequences (2009)

On the tube: The coupling of diazonium ions onto single-walled carbon nanotubes is shown to proceed through a radical chain reaction by kinetic analysis of the absorption peak drop (see picture). Radical species are also revealed by ESR. Metallic (m) nanotubes play a special catalytic role in the functionalization of semiconducting (sc) nanotubes.Due to its simplicity and versatility, diazonium coupling is the most widely used method for carbon nanotube (CNT) functionalization to increase CNT processability and add new functionalities. Yet, its mechanism is so far mostly unknown. Herein, we use kinetic analysis to shed light on this complex mechanism. A free-radical chain reaction is revealed by absorption spectroscopy and ESR. Metallic CNTs are shown to play an unexpected catalytic role. The step determining the selectivity towards metallic CNTs is identified by a Hammett correlation. A mechanistic model is proposed that predicts reactivity and selectivity as a function of diazonium electrophilicity and metallic-to-semiconducting CNT ratio, thus opening perspectives of controlled high-yield functionalization and purification.
TACITUS (1992)

The aim of the TACITUS project is to develop a general, domain-independent capability for text understanding that allows for variable levels of analysis, depending on the requirements of the task. Four stages of processing are being developed: preprocessing, syntactic analysis, inferential pragmatics processing, and template generation. Template generation is a straightforward programming task, but the other three stages of processing consititute research issues.
Assessment of concerns about vaccination among recovered COVID-19 patients in Saudi Arabia. (2023)

Overall concern about vaccination was high, and specific concerns were prevalent. Patient education on how the vaccine protects against reinfection should be targeted at COVID-19 patients before being discharged from hospital.
Traffic characteristics of H.264/AVC variable bit rate video (2008)

The recently developed H.264/AVC encoder compresses video significantly more efficiently than previous encoders and is expected to be used for compressing the majority of video transported over communication networks. The traffic characteristics of encoded video have a significant impact on the network transport of compressed video, making it very important to study the characteristics of H.264/AVC video traffic. In this article, we examine the bit-rate distortion performance, bit-rate variability, and long-range dependence of the H.264/AVC encoder for long videos up to high-definition resolution. We also explore the impact of smoothing on the H.264/AVC video traffic. We find that compared to the MPEG-2 and MPEG-4 Part 2 encoders, H.264/AVC achieves lower average bit rates for a given video quality at the expense of significantly increased traffic variability that remains at high levels even with smoothing.
Dynamic Tracking Area List configuration and performance evaluation in LTE (2010)

Reducing the signaling overhead for tracing user equipment (UE), while maintaining the improved performance over time despite the changes in UE location and mobility patterns, is a challenging issue in the area of mobility management. Flexibility and automatic reconfiguration are two significant features in Long Term Evolution (LTE) systems. The Tracking Area List (TAL) is a novel concept in LTE systems, which allows a more flexible configurations, expecting to reduce the overall signaling overhead. In this paper, we first present a ”rule of thumb” method to allocate and assign TALs for a network. The easily applied approach does not require any data other than what is available for conventional TA design. Second we compare the performance of an optimum conventional TA design with the suggested TAL design for a large scale network in Lisbon, Portugal. A thorough computation is done to make a justified evaluation. We follow the comparison during specific time intervals for one complete day, and we illustrate the performance of reconfiguration for each approach. The results clearly demonstrate the ability of dynamic TAL in reducing the signaling overhead and maintaining a good performance due to reconfiguration compared to the conventional TA design.
Dietary Problems Are Associated with Frailty Status in Older People with Fewer Teeth in Japan (2022)

This study aimed to investigate the association between dietary problems and frailty according to tooth loss in older Japanese people. This cross-sectional study included 160 older people (mean age 82.6 years) from Japan. Frailty status was assessed using the Study of Osteoporotic Fractures (SOF) criteria, which consists of (i) weight loss > 5% in the past year, (ii) inability to perform five chair stands, and (iii) self-perceived reduced energy level. Frailty was defined as the presence of ≥2 items of SOF criteria. Multivariate logistic regression analyses were performed with frailty as the dependent variable and dietary problems as the independent variable, stratified according to having <20 teeth. Low appetite and no enjoyment of eating were associated with frailty after adjusting for covariates in participants with <20 teeth. Dietary problems, including low appetite, eating alone, and negative attitudes toward enjoyment of eating were associated with a self-perceived reduced energy level in participants with <20 teeth. However, this association was not observed in participants with ≥20 teeth. In older people with fewer teeth, dietary problems have been suggested to be associated with frailty. Therefore, it may be necessary to pay attention to dietary problems, especially in older people with tooth loss.
Controlling Filler Distribution for Improved Fine Paper Properties (2004)

In this study, the main target was to control the filler distribution in the paper thickness direction and to evaluate its influence on some basic fine paper quality properties. The study was based upon pilot paper machine trials using wet end additives layering principles together with normal headbox and former controlling parameters. A statistical approach to the experimental results was used to extract the parameters for the models needed. The main focus of the study was on 50 and 80 g/m2 woodfree papers. The results showed a clear dependence of the quality of the woodfree paper on the filler distribution characteristics. Asymmetrical filler distributions contributed to low porosity, while the minimisation of oil absorption differences between surfaces was promoted by symmetrical filler distributions. This was particularly true with higher grammage papers.
Photoinduced Charge Separation in Riboflavin/Carbon Nanotubes Superstructures (2008)

A natural pigment, riboflavin (RF), was successful in immobilizing to the multiwalled carbon nanotubes (MWNTs) as antennae by a noncovalent approach. 1H NMR analysis indicated their π−π stacking interaction by the proton shift at the isoalloxazine ring of RF. Subsequently, time-resolved spectroscopic experiments were carried out to monitor the photoinduced charge separation states in the riboflavin/carbon nanotubes (RF/MWNTs) superstructures. It was found that charge separation was accessible in the superstructures with 355 nm laser excitation. The recombination of charge separation states was observed to be an obvious two-step process. A fast decay with a lifetime of ∼ 40 ns was attributed to the recombination of surface-immobilized RF radicals and localized electrons in MWNTs. Another relative longer process with a lifetime of ∼ 3.0 μs was assigned to the storage electron in MWNTs and thus retarded the recombination of charge separation states.
AUTOIMMUNE ENCEPHALITIS WITH ANTIBODIES AGAINST A-AMINO-3HYDROXY-5-METHYL-4-ISOXAZOLEPROPIONIC ACID RECEPTOR AND γ-AMINOBUTYRIC ACID-BETA RECEPTOR: CASE REPORT (2023)

In this case report, a case with coexistence of anti-GABA<sub>B</sub>R and anti-AMPAR antibodies, which has not been previously reported in the literature, is described. As more cases with the coexistence of these two antibodies are detected, knowledge on clinical aspect, laboratory and treatment will increase.
Extracorporeal Shock Wave Lithotripsy Retreatment (“Stir-Up”) Promotes Discharge of Persistent Caliceal Stone Fragments after Primary Extracorporeal Shock Wave Lithotripsy (1992)

A prospective randomized study was performed to compare the results of piezoelectric extracorporeal shock wave lithotripsy (ESWL) retreatment versus surveillance only in 50 patients with persistent caliceal stone fragments after primary ESWL for renal calculi. After a 3-month followup significant decreases in residual debris were observed in the retreated group, while changes in the control group were negligible. Considering the low morbidity of outpatient ESWL with a pain-free, second generation lithotriptor, ESWL retreatment of completely fragmented but persistent stone debris appears to be justified to render the kidney stone-free.

Differential effects of bryostatin 1 and phorbol ester on human breast cancer cell lines. (1992)

The effects of the protein kinase C (PKC) activators, phorbol ester 12-O-tetradecanoyl-13-phorbol acetate (TPA) and the marine natural product, bryostatin 1, on the growth and morphology of human breast cancer cell lines were examined. TPA (1 to 100 nM) inhibited growth of four of six cell lines by up to 75% in 5-day cultures. Bryostatin 1 inhibited growth of only MCF-7 cells and only at a high dose (100 nM). However, bryostatin 1 completely antagonized the growth inhibition and morphological changes induced by TPA in MCF-7 cells. The divergent effects of these two agents are associated with differing effects on PKC activity and isoform expression in MCF-7 cells. TPA induced rapid translocation of the PKC-alpha isozyme and PKC activity to the membrane fraction of MCF-7 cells. In contrast, bryostatin 1 treatment resulted in the loss of the PKC-alpha isozyme and PKC activity from both cytosolic and membrane compartments within 10 min of treatment. In coincubation assays the bryostatin 1 effect was dominant over that of TPA. Similar effects on PKC-alpha isozyme and PKC activity were seen in a second cell line whose growth was inhibited by TPA but not by bryostatin 1, MDA-MB-468. In contrast, in the T47D cell line, where TPA was not growth inhibitory, TPA failed to induce translocation of PKC-alpha to the cell membrane. Bryostatin, however, still caused loss of PKC-alpha isozyme and PKC activity from cytosolic and membrane fractions. Thus, differential actions of bryostatin 1 and TPA on PKC activity and alpha-isoform level in the membrane-associated fraction of MCF-7 and MDA-MB-468 cells may account for the divergent effects of these two agents on cell growth and morphology. These results suggest that the PKC-alpha isoform may specifically play a role in inhibiting growth of human breast cancer cells.

VECTOR CLUSTERING OF PASSIVE MILLIMETER WAVE IMAGES WITH LINEAR POLARIZATION FOR CONCEALED OBJECT DETECTION (2013)

Passive millimeter (MMW) imaging can penetrate cloth- ing to create interpretable imagery of concealed objects. However, the image quality is often restricted by low signal to noise ratio and temperature contrast as well as low spatial resolution. In this paper, we explore a four-channel passive MMW imaging system operating in the 8 and 3mm wavelength regimes with linear vertical and horizon- tal polarization directions. Both registration between difierent channel images and segmentation of concealed objects are addressed. Multi- channel image registration is performed by geometric feature matching and a-ne transform, and then multi-level segmentation separates the human body region from the background, and concealed objects from the body region, sequentially. In the experiments, several metallic and non-metallic objects concealed under clothing are captured in indoors. It will be shown that our method can separate objects with higher accuracy than the conventional method.
Pleiotropic effects of ticagrelor on microRNA expression in acute coronary syndrome on long term follow up (2020)

Abstract Background PLATO study showed that Ticagrelor (Ti) significantly reduced the rate of death from vascular causes, myocardial infarction or stroke without a significant increase of major bleeding vs Clopidogrel (Cl). Previous studies demonstrated the stronger direct anti-platelet effect of Ti versus Cl. Few data exist about the indirect anti-platelet properties and pleiotropic effects, eventually involved in the positive effect of Ti on acute coronary syndrome (ACS) outcome. Aim As Ti has multiple pleiotropic effects, we sought to assess whether the different outcome of Ti versus Cl in NSTE-ACS patients could be explained, at least in part, by different modulation of circulating microRNA (miRNA). The primary endpoint was to characterize the effect of the two different P2Y12 inhibitors on miRNA expression. Secondary endpoint was to correlate miRNA profile to clinical outcome. Methods Thirty-one patients with a diagnosis of NSTE-ACS were enrolled in this study. Patients were randomized for Ti or Cl assumption before undergoing PCI. Clinical characteristics were homologues between Ti and Cl groups. Blood samples were drawn at different time point (T0, T1 and T2) to test miRNA modulation and stability (T0, at baseline; T1, three hours after drug administration; T2, twenty-four hours after coronarography). Plasma RNA was extracted and pooled for microarray PCR based panel of ninety miRNA analysis. MiRNA expression was normalized on the global mean of each patient. Levels of circulating miRNAs were compared using statistical tests, assuming significance at P&amp;lt;0,05. Results A panel of seven circulating miRNAs associated with atherosclerosis, thrombosis and inflammation were selected for validation (miR-652-3p; miR-26-5p; miR-25-3p; miR-let7c; miR-155-5p; miR-222-3p; miR-223-3p). Microarray analysis showed an opposite modulation of most miRNAs at T0, T1 and T2 in patients with Cl or Ti treatment. In particular, Cl group showed an upregulation of most miRNAs, while Ti administration caused their down-regulation. Of the seven miRNA selected for validation, miR-652-3p, expression at T1 showed a significantly modulation in patients in Cl treatment compared to Ti (T1 Cl 2,637±1,092, T1 Ti 0,660±0,171; p=0.03). MiRNA-652-3p has a validated pro-atherogenic role. On five-years follow, an higher rate (40%) of cardiovascular events (new ACS, recurrent ischemia and stent thrombosis) was reported in the Cl group compare to Ti. Indeed, no one death or bleeding occurred. Conclusion This data suggest that Ti has a protective role down-regulating pro-atherogenic and pro-thrombotic miRNAs (miR-652-3p, miR-let7c, miR-223-3p, miR-155-5p) and promoting the expression of anti-atherogenic miRNAs (miR-25-3p) when compared to Cl. This may contribute to explain the positive effect on clinical outcome of Ti. Although the small number of patients, this pilot study gives another evidence about the multiple positive pleiotropic effect of Ti.

A Baseball Player with a Swollen Arm (2020)

A 23-year-old right-handed baseball player visited our hospital with nominal swelling of his right arm (Picture 1). Ultrasonography and contrast-enhanced computed tomography revealed a thrombus from the subclavian vein to the axillary vein (Picture 2, 3). He was diagnosed with Paget von Schroetter syndrome (PSS) and treated by catheter-directed thrombolysis with urokinase followed by the administration of direct oral anticoagulant. By the next day, the swelling had improved, and the size of the thrombus had reduced (Picture 4). There was no recurrence for six months. PSS is effort-induced thrombosis of the axillary and subclavian
Active sensing for range-only mapping using multiple hypothesis (2010)

Radio signal-based localization and mapping is becoming more interesting in robotics as applications involving the collaboration between robots and static wireless devices are more common. This paper describes a method for mapping with a mobile robot the position of a set of nodes using radio signal measurements. The method employs Gaussian Mixtures Models (GMM) for undelayed initialization of the position of the wireless nodes within a Kalman filter. Moreover, the paper extends the method to consider active sensing strategies in order to map the nodes. Entropy variation is used as a measurement of information gain, and allows to prioritize control actions of the robot. However, as there is no analytical expression for the entropy of a GMM, upper bounds of the entropy, for which close form computation is possible, are used instead. The paper describes simulations that show the feasibility of the approach.
Growing Use of Medicinal Botanicals Forces Assessment by Drug Regulators (1995)

THE GROWING USE of botanicals (drugs and other products derived from plants) by the US public is forcing moves to evaluate the health claims of these agents and to develop standards of quality and manufacture. The parties involved—herbal therapists, manufacturers, processors, and distributors of botanicals—and the Food and Drug Administration (FDA) are circling each other warily. But at a meeting in Washington, DC, sponsored by the National Institute of Health's Office of Alternative Medicine in cooperation with the FDA, all these parties had a frank exchange about the issues that must be addressed if botanical products are to enter the mainstream of medical practice. <h3>Need Scientific Evidence</h3> "There are estimates that as many as one in three Americans are using some form of alternative medicine," said Devra Lee Davis, PhD, MPH, senior adviser to the Assistant Secretary for Health. "Botanicals are becoming widely used. We have to assess a process
High Performance Microcoulometry (2007)

The purpose of this work is the development of microcoulometric cell for measurement of halogenide ions in the range of ng amounts. The main task in the innovation is to fulfil the need of sensitive halogene determination in the automated measurement of the so-called adsorbable organically bound halogens (AOX) in waters. The very low consumption of supporting electrolyte and the energy saving configuration is also important factors in designing of monitor operation. We developed a micro volume tube reactor, which can work continuously with peristaltic pumps feeding the supporting electrolyte and the sample. The tube cell allows the injection of liquid and gas samples without changing the cell construction. A three electrode type potentiostatic microcoulometer with a rotating Ag working electrode was built, which maintains a constant electrode potential of the working electrode to the reference electrode by the generation of silver ions through anodic dissolution. The halogenide ions in sample solution change the electrode potential of the working electrode. The potentiostatic controller circuit sets a current flowing between the Ag working (anode) and a counter electrode (cathode). This current generates silver ions from the working electrode, these ions precipitate the halogenide ions from the cell electrolyte and restore the potential of the working electrode. It was a further successful hydraulic development to achieve a microvolume cell, which accepts both gas and liquid samples in the same equipment. The developed microcoulometer system has high sensitivity and works reliable in a wide measuring range.
2905 Driving Mechanism of a Small Wiper with Piezoelectric Actuators (2005)

Dynamic behavior of a small wiper with piezoelectric actuators, which is applied for a small CCD camera, is discussed in order to clarify the driving mechanism of it. First, the rotational motion of the wiper is modeled as a rotational motion of the cantilever with bending vibration. Next, the driving mechanism of the wiper is discussed and clarified theoretically by using the derived equations of the turning angle and the bending deflection. The influence of the frictional force that works between the wiper blade and glass surface is also taken into consideration. Finally, the rotational motion of the wiper due to the bending vibration, which is predicted by the theory, is confirmed with the experiment.
