A Base-Band Comb Filter for Consumer Television Receivers (1980)

Since the inception of color TV twenty-five years ago, there has been a continual improvement in the performance and features available in consumer television receivers. Advancements in circuit and device technologies have made their way from the research laboratories into consumer products as economics has permitted. So it is that now the circuit techniques of comb filtering, which have been known for decades, have become viable in consumer TV through the recent advancements in charge coupled devices and in MOS integrated circuits. These technologies can now be married with TV circuit designs to open new realms of picture resolution, freedom from interference between the luminance and chrominance signals and a new dimension of picture sharpness through the addition of vertical detail enhancement.
High-Density Resource-Restricted Pulse-Based IoT Networks (2021)

For the realization of an Internet of Things (IoT) with high densities of devices it is necessary that wireless communication protocols are developed that offer 1) low energy consumption; 2) simplicity of encoding and decoding; 3) an asynchronous mode of communication; and 4) an effective but simple method to deal with interference between transmissions. This paper presents the implementation, experimentation, and analysis of a protocol on the MAC sublayer that encodes information in terms of silent intervals between pulses. Based on the representation of patterns of sparse pulses, this encoding has the potential for extremely low power consumption at the transmitter side. It also results in only few conflicts between messages that are broadcast on the same band overlapped in time, while no synchronization between transmitters and receivers is necessary. The protocol is demonstrated experimentally on the 315 MHz band with 100 senders and one receiver configured in a Star topology. Theoretical analysis confirms that the probability of conflicts between messages is low, even if the number of devices increases to the order of ten thousand. This protocol facilitates the implementation of IoT devices that are restricted in terms of hardware and energy resources.

Air-stable chemical doping of carbon nanotube transistors (2004)

In this paper, we have successfully demonstrated, for the first time, air-stable chemical p-doping of CNFETs via charge transfer; introduced tunability of the V/sub th/, transformed scaled CNFETs from ambipolar to unipolar, improved I/sub on/ by 2-3 orders of magnitude, suppressed minority carrier injection (immunity from drain induced I/sub off/ degradation from intrinsic Schottky barrier CNFET), yielding an excellent I/sub on//I/sub off/ ratio of 10/sup 6/, and demonstrated excellent DIBL-like behavior.
Neuroinflammation is increased in the parietal cortex of atypical Alzheimer’s disease (2018)

Our data show a different localization of neuroinflammatory markers and amyloid-beta plaques between AD phenotypes. In addition, these markers reflect the atypical distribution of tau pathology in atypical AD, suggesting that neuroinflammation might be a crucial link between amyloid-beta deposits, tau pathology, and clinical symptoms.

[Secondary surgery for restoration of nerve function (author's transl)]. (1980)

The technique of nerve-suturing belongs in modern times to the domain of microsurgery. Without implementing the posibilities offered by microsurgery, nerve-suturing - even directly end-to-end - is obsolete. In order to obtain a sufficient functional end-result, suturing under tension must be avoided at all costs. Knowledge of this has given rise to the common interposition nerve grafts. Even with interposition grafts, no cases of growth-disturbances, including a failure of the nerve to grow or disturbances in function because of growth, have been observed in children. For a good post-op. results, a continual therapy with neurotropic medicaments, physiotherapy and faradisation, and neurophysiological checks on progress made in renervation are absolutely essential.
Mismatch-shaping serial digital-to-analog converter (2003)

A simple but accurate pseudo-passive mismatch-shaping D/A converter is described. A digital state machine is used to control the switching sequence of a symmetric two-capacitor network that performs the D/A conversion. The error caused by capacitor mismatch is uncorrelated with the input signal and has only little power in the signal band. The system has been simulated assuming a 0.1% capacitor mismatch, and the achieved SNDR performance was 100 dB for an oversampling ratio of 7.

Particleboards with Agricultural Wastes: Sugar Cane Bagasse and Reforestation Wood (2014)

In this paper, it was consider the study of the use of sugarcane bagasse and wood particles, residues from the agricultural and the furniture industry, in order to add value to such materials. To add value to these materials it will be utilized in the manufacturing of hybrid panels consisting of wood particles and sugarcane bagasse in certain proportions (20%, 40% and 60%). For the production it was used the bi-component polyurethane resin based on castor oil. Analysis of the products was established based on the physical-mechanical standard NBR 14.810:2006. The hybrid panels were analyzed according to the data obtained in relation to the American standard ANSI A208.1-1999, in order to determine the best treatment for the possible use as a lining in agricultural buildings. Moreover, the hybrid panels were contrasted with panels of other formulations, with similar density. It was evident that the treatment constituting of 40% of sugar cane bagasse and 60% of wood particles had the best physical-mechanical, and showed a potential for the use in non-structural applications.
The Fuzzy Emotion Recognition Framework Using Semantic-Linguistic Facial Features (2019)

Emotion recognition through facial expression analysis is an emerging research in Artificial Intelligence which faces many challenges. The problem is the variation of facial expressions that displays human emotions. Humans can subjectively express the same emotions in various ways. To overcome the problem of ambiguity in emotion expression, a fuzzy approach is developed to analyze the facial components in determining the type of emotion. In this study, we proposed a framework for fuzzy emotion recognition as a representation of the psychologist knowledge. Three stages in the fuzzy emotion recognition were facial feature extraction with Active Appearance Model; Semantic-linguistic facial features extraction; fuzzy emotion recognition with Fuzzy Emotion Classification. System performance testing provided the best results on extended Cohn Kanade (CK+) facial expression dataset, with the accuracy of linguistic facial component recognition 0.98, and accuracy of fuzzy emotion recognition 0.90. Testing was also performed on custom-made Indonesian Mixed Emotion Dataset (IMED) which resulted in accuracy of 0.87. The fuzzy emotion recognition has a potential to be applied in various real problems such as virtual counseling, stress detection, lie detection, and e-commerce.
Assessing the longitudinal associations between decision-making processes and attention problems in early adolescence (2023)

Cognitive functions and psychopathology develop in parallel in childhood and adolescence, but the temporal dynamics of their associations are poorly understood. The present study sought to elucidate the intertwined development of decision-making processes and attention problems using longitudinal data from late childhood (9-10 years) to mid-adolescence (11-13 years) from the Adolescent Brain Cognitive Development (ABCD) Study (n=8918). We utilised hierarchical drift-diffusion modelling of behavioural data from the stop-signal task, parent-reported attention problems from the Child Behavior Checklist (CBCL), and multigroup univariate and bivariate latent change score models. The results showed faster drift rate was associated with lower levels of inattention at baseline, as well as a greater reduction of inattention over time. Moreover, baseline drift rate negatively predicted change in attention problems in females, and baseline attention problems negatively predicted change in drift rate. Neither response caution (decision threshold) nor encoding- and responding processes (non-decision time) were significantly associated with attention problems. There were no significant sex differences in the associations between decision-making processes and attention problems. The study supports previous findings of reduced evidence accumulation in attention problems and additionally shows that development of this aspect of decision-making plays a role in developmental changes in attention problems in youth.
Mapping the use of computational modelling and simulation in clinics: A survey (2023)

<i>In silico</i> medicine describes the application of computational modelling and simulation (CM&S) to the study, diagnosis, treatment or prevention of a disease. Tremendous research advances have been achieved to facilitate the use of CM&S in clinical applications. Nevertheless, the uptake of CM&S in clinical practice is not always timely and accurately reflected in the literature. A clear view on the current awareness, actual usage and opinions from the clinicians is needed to identify barriers and opportunities for the future of <i>in silico</i> medicine. The aim of this study was capturing the state of CM&S in clinics by means of a survey toward the clinical community. Responses were collected online using the Virtual Physiological Human institute communication channels, engagement with clinical societies, hospitals and individual contacts, between 2020 and 2021. Statistical analyses were done with R. Participants (<i>n</i> = 163) responded from all over the world. Clinicians were mostly aged between 35 and 64 years-old, with heterogeneous levels of experience and areas of expertise (<i>i.e.,</i> 48% cardiology, 13% musculoskeletal, 8% general surgery, 5% paediatrics). The CM&S terms "Personalised medicine" and "Patient-specific modelling" were the most well-known within the respondents. "In silico clinical trials" and "Digital Twin" were the least known. The familiarity with different methods depended on the medical specialty. CM&S was used in clinics mostly to plan interventions. To date, the usage frequency is still scarce. A well-recognized benefit associated to CM&S is the increased trust in planning procedures. Overall, the recorded level of trust for CM&S is high and not proportional to awareness level. The main barriers appear to be access to computing resources, perception that CM&S is slow. Importantly, clinicians see a role for CM&S expertise in their team in the future. This survey offers a snapshot of the current situation of CM&S in clinics. Although the sample size and representativity could be increased, the results provide the community with actionable data to build a responsible strategy for accelerating a positive uptake of <i>in silico</i> medicine. New iterations and follow-up activities will track the evolution of responses over time and contribute to strengthen the engagement with the medical community.
Robotic home assistant Care-O-bot: past-present-future (2002)

Technical aids allow elderly and handicapped people to live independently in their private homes as long as they wish. As a contribution to such technological solutions, a demonstrator platform for a mobile home care system - called Care-O-bot - was designed and implemented by Fraunhofer IPA, Stuttgart. Care-O-bot is a mobile service robot which has the capability to perform fetch and carry and various other supporting tasks in home environments. This paper gives an overview about Care-O-bot's functionalities and first practical tests.
Cell-Adhesive Responses to Tenascin-C Splice Variants Involve Formation of Fascin Microspikes (1997)

Tenascin-C is an adhesion-modulating matrix glycoprotein that has multiple effects on cell behavior. Tenascin-C transcripts are expressed in motile cells and at sites of tissue modeling during development, and alternative splicing generates variants that encode different numbers of fibronectin type III repeats. We have examined the in vivo expression and cell adhesive properties of two full-length recombinant tenascin-C proteins: TN-190, which contains the eight constant fibronectin type III repeats, and TN-ADC, which contains the additional AD2, AD1, and C repeats. In situ hybridization with probes specific for the AD2, AD1, and C repeats shows that these splice variants are expressed at sites of active tissue modeling and fibronectin expression in the developing avian feather bud and sternum. Transcripts incorporating the AD2, AD1, and C repeats are present in embryonic day 10 wing bud but not in embryonic day 10 lung. By using a panel of nine cell lines in attachment assays, we have found that C2C12, G8, and S27 myoblastic cells undergo concentration-dependent adhesion to both variants, organize actin microspikes that contain the actin-bundling protein fascin, and do not assemble focal contacts. On a molar basis, TN-ADC is more active than TN-190 in promoting cell attachment and irregular cell spreading. The addition of either TN-190 or TN-ADC in solution to C2C12, COS-7, or MG-63 cells adherent on fibronectin decreases cell attachment and results in decreased organization of actin microfilament bundles, with formation of cortical membrane ruffles and retention of residual points of substratum contact that contain filamentous actin and fascin. These data establish a biochemical similarity in the processes of cell adhesion to tenascin-C and thrombospondin-1, also an "antiadhesive" matrix component, and also demonstrate that both the adhesive and adhesion-modulating properties of tenascin-C involve similar biochemical events in the cortical cytoskeleton. In addition to these generic properties, TN-ADC is less active in adhesion modulation than TN-190. The coordinated expression of different tenascin-C transcripts during development may, therefore, provide appropriate microenvironments for regulated changes in cell shape, adhesion, and movement.
Photoactive antimicrobial PVA hydrogel prepared by freeze‐thawing process for wound dressing (2010)

Abstract A freeze‐thawing process was employed to produce both rose bengal (RB)/polyvinyl alcohol (PVA) and benzophenone (BP)/PVA hydrogels, respectively. Results indicated that only RB incorporated PVA (RB/PVA) could form hydrogel after undergoing three cycles of freeze‐thawing process; One of the cycles should be conducted by freezing at −15°C ± 3°C for 18 h followed by thawing at 25°C for 6 h. The structural features and functional properties of the RB/PVA hydrogel were investigated by FTIR, XRD, SEM evaluations, and photo‐induced antimicrobial functions were examined as well. Release of RB from the RB/PVA hydrogel was examined by UV‐Vis spectroscopy. The freeze‐thawed RB/PVA hydrogel showed antimicrobial abilities against both E. coli and S. aureus under the exposure to fluorescence light as well as UVA (365 nm) light. © 2010 Wiley Periodicals, Inc.

Dual-Band Differential Phase Shifter Using Phase- Slope Alignment on Coupled Resonators (2018)

In this letter, we propose a new class of phase shifter which can provide different constant phase shifts at two bands for the first time. The prescribed phase shifts AΦ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> (f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> ) and AΦ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> (f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) and frequency ratio (n = f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> /f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> ) of the two bands can be obtained by the developed dual-band phase-shifting line on C-section. Meanwhile, the dual-band phase-slope alignment is first realized by virtue of the two groups of coupled resonators, resulting to independently control the phase slopes at two separated bands as required. The closed-form equations and design charts are further given. For verification, a prototype dual-band phase shifter operating at 3.0 and 5.4 GHz (n = 1.8) is designed, fabricated, and tested. The measured results show the proposed phase shifter exactly achieves prescribed constant phase shifts of 90° ± 2.3° over 2.76-3.31 GHz (18%) and 180° ± 2.7° over 4.97-5.80 GHz (15%). Both the simulation and measured results are recorded with good agreement.
Polymorphism of triglycerides a crystallographic review (1990)

In order to understand I he role of fat in food systems detailed knowledge about the arrangement of triglyceride molecules is useful. The triglyceride molecules in a fat can be packed in alternative ways, each crystal form having different melting points. This phenomenon is called polymorphism. Based mainly on X-ray studies (single-crystal, powder diffraction , scattering) and Raman spectroscopy the structure of the different polymorphic forms, a, sub-a, P'2. P't and~. are explained. The emphasis is on work done in the author's laboratory. There is a close relationship between the polymorphic forms which is persistent also in the liquid state - the molecules are arranged two and two in a bilayer. The differences between the polymorphic forms are due to: (i) the hydrocarbon chain packing, (ii) the tilt of the chains versus the methyl end group plane, and (iii) differences in the methyl end group region. From a technical point of view the polymorphic transitions of fats is of the highest importance. This paper describes a mechanism behind the B --> B transition - the chain mobility in the methyl end group region causes this transition.
Timing verification using HDTV (1990)

A system designed for verifying the consistency of timing specifications for digital circuits is presented. The utility of the system comes from the need to verify that existing digital components will interact correctly when placed together in a system. To perform this interface verification, two operators are defined which allow one to perform useful reasoning concerning the interface. One operator deals with causality and another with timing constraints. The system can also be used in the case of verifying specifications of unimplemented components. The system is implemented as a hardware design timing verification (HDTV) program. >
Targeting Src and Tubulin in Mucinous Ovarian Carcinoma (2013)

Our results showed that targeting both the Src pathway and tubulin with KX-01 significantly inhibited tumor growth in preclinical mucinous ovarian cancer models, suggesting that this may be a promising therapeutic approach for patients with mucinous ovarian carcinoma.
Enhanced sensitivity to hypoxia-induced diastolic dysfunction in pressure-overload left ventricular hypertrophy in the rat: role of high-energy phosphate depletion. (1988)

Isolated buffer-perfused rat hearts with pressure-overload hypertrophy develop a greater decrease in left ventricular (LV) diastolic distensibility and a greater impairment in extent of LV relaxation in response to hypoxia than do normal hearts. Using 31P-NMR spectroscopy, we tested the hypothesis that the enhanced susceptibility of hypertrophied hearts to develop hypoxia-induced diastolic dysfunction is due to an accelerated rate of ATP and/or creatine phosphate depletion. Twelve minutes of hypoxia were imposed on isolated isovolumic (balloon-in-left-ventricle) buffer-perfused hearts from 14 rats with pressure-overload hypertrophy (LVH; LV/body wt ratio = 3.43 +/- 17) secondary to hypertension induced by uninephrectomy plus deoxycorticosterone and salt treatment and from 17 age-matched controls (LV/body wt ratio = 2.22 +/- 0.12, p less than 0.001). Coronary artery flow per gram left ventricle was matched in the LVH and control groups during baseline oxygenated conditions and held constant thereafter. Balloon volume was held constant throughout the experiment so that an increase in LV end-diastolic pressure during hypoxia represented a decrease in LV diastolic distensibility. LV systolic pressure was 165 +/- 9 mm Hg in the LVH group compared with 120 +/- 5 mm Hg in the controls during baseline aerobic perfusion (p less than 0.001). LV end-diastolic pressure rose significantly more in response to 12 minutes of hypoxia in the LVH group (12 +/- 1 to 44 +/- 10 mm Hg) than in the controls (12 +/- 1 to 20 +/- 3 mm Hg, p = 0.04). During baseline aerobic conditions, ATP content was the same in the LVH (17.1 +/- 0.5 mumol/g dry LV wt, n = 4) and control (18.8 +/- 0.6 mumol/g dry LV wt, n = 4, p = NS) groups. During hypoxia, ATP declined at the same rate in the LVH and control groups (3.2 +/- 0.5 versus 3.0 +/- 0.5%/min, p = NS) despite the greater rise in end-diastolic pressure in the LVH group. Creatine phosphate content during baseline aerobic perfusion was 14% lower in the LVH group compared with controls, but the rate of creatine phosphate depletion during 12 minutes of hypoxia was the same. During hypoxia, intracellular pH declined modestly and to the same degree in both groups. Thus, the greater susceptibility to hypoxia-induced diastolic dysfunction observed in isolated buffer-perfused hypertrophied rat hearts cannot be explained by an initially lower total ATP content or by an accelerated rate of decline of ATP or creatine phosphate.(ABSTRACT TRUNCATED AT 400 WORDS)
