A doubly fed induction generator usingback-to-back PWM converterssupplying an isolated load from a variable speed wind turbine (1996)

A doubly fed induction generator (DFIG) designed to be driven at variable speed from a wind turbine and supplying an isolated load is presented. Two back-to-back PWM voltage-fed inverters connected between the stator and the rotor allow sub- and super-synchronous operation with low distortion currents. The load voltage is maintained at constant frequency and its magnitude is regulated through control of the stator flux of the generator. An auxiliary load is connected in parallel with the main load, and the auxiliary power is controlled to allow the DFIG to track the optimal wind turbine speed for maximum energy capture from the wind. An indirect stator-orientated vector control scheme is used to control the DFIG and this results in constant load voltage and frequency for variations in both load and wind speed. The techniques have been implemented and validated on a 7.5 kW experimental rig.
Multi-step domain adaptation by adversarial attack to $\mathcal{H} Δ\mathcal{H}$-divergence (2022)

Adversarial examples are transferable between different models. In our paper, we propose to use this property for multi-step domain adaptation. In unsupervised domain adaptation settings, we demonstrate that replacing the source domain with adversarial examples to $\mathcal{H} Δ\mathcal{H}$-divergence can improve source classifier accuracy on the target domain. Our method can be connected to most domain adaptation techniques. We conducted a range of experiments and achieved improvement in accuracy on Digits and Office-Home datasets.
Electrolyte‐Gated Organic Field‐Effect Transistor Based on a Solution Sheared Organic Semiconductor Blend (2016)

This communication presents a novel electrolyte gated field-effect transistor based on a blend of dibenzo-tetrathiafulvalene and polystyrene deposited through bar-assisted meniscus shearing. This technique allows the fabrication of high performing electronic devices suitable for (bio)sensing applications and might capture industrial interest due to its scalability. The reported devices can operate in aqueous solution with comparable complexity to real samples.
Ofdm synchronization using pn sequence and its performance (2004)

In this paper, we propose a novel method for orthogonal frequency-division multiplexing (OFDM) time and frequency synchronization by using PN sequence and barker code, time synchronization performance is improved by barker code, and we also propose a simple but effective method by setting the threshold during time synchronization. Improved frequency synchronization algorithm is presented in this paper too. The idea of multipath utilizing is the core of the frequency synchronization algorithm. The performance of the synchronization proposed here is better than that of conventional methods. Estimation precision is boosted from 10/sup -3/ to 10/sup -4/ for moderate SNR. The requirements of time and frequency synchronization for beyond 3G system based on OFDM can be well satisfied while using the proposed method.

On the Performance Analysis of Hybrid ARQ With Incremental Redundancy and With Code Combining Over Free-Space Optical Channels With Pointing Errors (2014)

In this paper, we investigate the performance of hybrid automatic repeat request (HARQ) with incremental redundancy (IR) and with code combining (CC) from an information-theoretic perspective over a point-to-point free-space optical (FSO) system. First, we introduce new closed-form expressions for the probability density function, the cumulative distribution function, the moment generating function, and the moments of an FSO link modeled by the Gamma fading channel subject to pointing errors and using intensity modulation with direct detection technique at the receiver. Based on these formulas, we derive exact results for the average bit error rate and the capacity in terms of Meijer's G functions. Moreover, we present asymptotic expressions by utilizing the Meijer's G function expansion and using the moments method, too, for the ergodic capacity approximations. Then, we provide novel analytical expressions for the outage probability, the average number of transmissions, and the average transmission rate for HARQ with IR, assuming a maximum number of rounds for the HARQ protocol. Besides, we offer asymptotic expressions for these results in terms of simple elementary functions. Additionally, we compare the performance of HARQ with IR and HARQ with CC. Our analysis demonstrates that HARQ with IR outperforms HARQ with CC.
The levator–urethra gap measurement: a more objective means of determining levator avulsion? (2008)

The measurement of LUG is reproducible and strongly associated with levator avulsion trauma diagnosed on vaginal palpation. A cut-off of 25 mm may be used for the diagnosis of levator avulsion injury.
Statistical models of trust: TCBs vs. people (2003)

The processes of granting security clearances to people and accrediting trusted computer systems are compared, both informally and using preliminary mathematical models of risk probabilities. The risk models support the validity of two hypotheses that were previously merely conjectures: (1) in determining an acceptable accreditation range for a computer one need only consider the highest classification of data on it and the least-cleared person using it, (2) that under suitable conditions a cascade (combination) of two trusted systems can be trusted more than either individually. In particular, it is shown that a cascade of two (independently built) B2 systems is as good as one B3 system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Mitochondrial Apoptosis and the Peripheral Benzodiazepine Receptor (2002)

Viruses mercilessly exploit their host cells to guarantee their own proliferation and propagation. To achieve this goal, many viruses suppress the apoptotic program, thereby avoiding premature death of the host cell. Indeed, apoptosis of infected cells may be considered as a pristine defense against
Facilitation by the β2a subunit of pore openings in cardiac Ca2+ channels (1998)

1. Single channel recordings were performed on the cardiac calcium channel (alpha1C) in order to study the effect of coexpression of the accessory beta2a subunit. On-cell patch clamp recordings were performed after expression of these channels in Xenopus oocytes. 2. The alpha1C subunit, when expressed alone, had similar single channel properties to native cardiac channels. Slow transitions between low and high open probability (Po) gating modes were found as well as fast gating transitions between the open and closed states. 3. Coexpression of the beta2a subunit caused changes in the fast gating during high Po mode. In this mode, open time distributions reveal at least three open states and the beta2a subunit favours the occupancy of the longest, 10-15 ms open state. No effect of the beta2a subunit was found when the channel was gating in the low Po mode. 4. Slow gating transitions were also affected by the beta2a subunit. The high Po mode was maintained for the duration of the depolarizing pulse in the presence of the beta2a subunit; while the alpha1C channel when expressed alone, frequently switched into and out of the high Po mode during the course of a sweep. 5. The beta2a subunit also affected mode switching that occurred between sweeps. Runs analysis revealed that the alpha1C subunit has a tendency toward non-random mode switching. The beta2a subunit increased this tendency. A chi2 analysis of contingency tables indicated that the beta2a subunit caused the alpha1C channel to gain 'intrinsic memory', meaning that the mode of a given sweep can be non-independent of the mode of the previous sweep. 6. We conclude that the beta2a subunit causes changes to the alpha1C channel in both its fast and slow gating behaviour. The beta2a subunit alters fast gating by facilitating movement of the channel into an existing open state. Additionally, the beta2a subunit decreases the slow switching between low and high Po modes.
An Analysis of the Nutritional Adequacy of Mass-Marketed Vegan Recipes (2023)

The popularity of plant-based and vegan diets has grown in recent years. While following a vegan diet has been associated with various health benefits, the intake of certain vitamins and minerals including vitamins B12 and D, calcium, and iron, are likely to be inadequate in an exclusively plant-based diet. Low nutrient intake over time can lead to nutritional deficiencies and potentially increased risk of adverse health outcomes. In this study, we analyzed a one-week meal plan comprised of vegan recipes from Forks Over Knives (FOK), an organization that promotes a low-fat, whole-food, vegan diet to prevent or reverse chronic disease. A detailed analysis of the meal plan found that it was deficient in several nutrients. It did not meet at least 90% of the daily value (DV) for the following: biotin (56% DV), calcium (58% DV), choline (30% DV), iodine (1% DV), niacin (75%), selenium (68%), vitamin B12 (82% DV), vitamin D (5% DV), vitamin E (7% DV), and zinc (64% DV). Based on evidence from this analysis, vegans and their healthcare providers should be aware of potential nutrient deficiencies and health consequences that may result from this type of diet.
Synthesis of myo-Inositol Polyphosphates (1991)

The total synthesis of many naturally occurring myo-inositol phosphates are reported. The syntheses feature the use of camphanic acid esters for resolution of protected inositols. The efficient phosphorylation of hydroxyl groups was achieved by the use of tetrabenzylpyrophosphate followed by hydrogenolysis of the benzyl protecting groups to obtain the pure phosphates.
Health and wellness: the shift from managing illness to promoting health. (2008)

Despite an acknowledged lack of evidence of investment payoff, health plan initiatives to promote health and wellness are now commonplace, according to findings from the Center for Studying Health System Change's (HSC) 2007 site visits to 12 nationally representative metropolitan communities. Much of the impetus has come from employers--primarily large employers--that are incorporating health and wellness activities into benefit designs that place more responsibility on employees for health care decisions and costs. Health plans now offer a range of health and wellness activities, including traditional worksite health fairs, screenings and educational seminars; access to behavior modification programs, such as weight management and smoking cessation; and online tools, including health risk assessments. Engaging enrollees in these activities, however, is challenging because participation typically is voluntary. Another barrier is employee privacy concerns. More health plans and employers are turning to financial incentives to secure greater participation. Ultimately, however, the credibility of health and wellness activities as mechanisms to improve health and contain costs is dependent on evidence demonstrating their clinical and financial effectiveness, as well as consumers' acceptance and validation of their legitimacy.

Reduction of human visual cortex excitability using 1-Hz transcranial magnetic stimulation (2000)

The effects of low-frequency (1-Hz) repetitive transcranial magnetic stimulation on visual cortex excitability were investigated by measuring phosphene thresholds (PTs) and stimulus-response curves. Stimulation over the visual cortex led to significantly decreased visual cortex excitability, expressed as an increase in PT. The motor threshold of the hand muscles did not change, indicating the topographic specificity of this effect. This intervention may be useful in situations associated with a hyperexcitable visual cortex.

Preços relativos e concentração na indústria brasileira: análise das fases de expansão e retração da atividade econômica de 1974 a 1994 (1996)

RESUMO Este artigo examina o comportamento do preço relativo da indústria brasileira nas fases de expansão e retração do nível de atividade econômica entre 1974-1994. Os resultados sugerem que os preços relativos do setor oligopolista aceleram mais (menos) em períodos de recessão (expansão) do que o setor competitivo. A principal conclusão é que, dado o comportamento diferenciado no preço e a baixa concorrência da maioria da indústria brasileira, é provável que o resultado da recessão de uma política econômica restrita seja absorvido pelo setor competitivo “a favor” do setor oligopolista.
Melatonin and Malignant Disease (1985)

A possible role for the pineal and melatonin in malignant disease is suggested by the studies of hormone-dependent tumours presented here. The most dramatic observation of the effect of the pineal and melatonin in malignancy is that melatonin protects against, while pinealectomy enhances, 7,12-dimethylbenz[a]anthracene-induced mammary tumours in rats. Melatonin may protect against tumours through a suppressive effect on prolactin secretion or an action on oestrogen receptors. Melatonin can change the concentration of oestrogen receptors in hamsters, both juvenile and adults, and in a human breast cancer cell line. The long-term effect of melatonin in the ovariectomized adult hamster and in human breast cancer cells is to inhibit oestrogen-stimulated growth. A possible relationship between melatonin and oestrogen receptors was examined in women with breast cancer. An inverse correlation was observed between the oestrogen receptor concentration in each patient's tumour and her peak plasma melatonin level, suggesting that the more hormone dependent the breast cancer the more blunted the daily melatonin rhythm. Thus, the more robust the daily melatonin rhythm the greater the protective effect on hormone-dependent breast cancer. Unfortunately, this hypothesis is not easily tested as shown in a study of women at high risk for developing breast cancer. These women had daily melatonin profiles that did not differ from those of a normal population. Thus, the use of plasma melatonin as a screening tool for breast cancer risk is not reasonable; however the basic and clinical data argue that the role of melatonin in endocrine-related cancers requires more extensive clinical investigation.
DC-link Current Harmonic Mitigation via Phase-shifting of Carrier Waves in Paralleled Inverter Systems (2021)

DC-connected parallel inverter systems are gaining popularity in industrial applications. However, such parallel systems generate excess current ripple (harmonics) at the DC-link due to harmonic interactions between the inverters in addition to the harmonics from the PWM switching. These DC-link harmonics cause the failure of fragile components such as DC-link capacitors. This paper proposes an interleaving scheme to minimize the current harmonics induced in the DC-link of such a system. The results show that when the carrier waves of the two inverters are phase-shifted by 90° angle, the maximum high-frequency harmonic ripple cancellation occurs, which reduces the overall RMS value of the DC-capacitor current.The outcome of this proposed solution is a cost-effective DC-harmonics mitigating strategy for the industrial designers to practically configuring multi-inverter systems, even when most of the drives are not operating at rated power levels. Experimental and simulation results presented in this paper verify the effectiveness of the proposed carrier-based phase-shifting scheme for two different configurations of common DC connected multi-converter systems.
Exploring Low Loss Suspension Interconnects for High Data Rates in Hard Disk Drives (2007)

For high data rate applications, current suspension interconnect solutions should stay above 50 Ohm differential impedance (Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">diff</sub> ) due to footprint limitations and frequency dependent ohmic losses of the stainless steel plane at low Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">diff</sub> . This paper describes the impedance and bandwidth (BW) design space of today's interconnects and also shows why this technology is still compatible with current system front-ends up to 3 Gb/s. Furthermore, the benefits of reduced power and higher overshoot using less than 50 Ohm impedance and high bandwidth interconnects are explored with a system model. Three alternate low impedance interconnect structures are used to demonstrate these benefits, and are explored analytically and evaluated for mechanical tradeoffs.
Security Challenges for User-Oriented RFID Applications within the "Internet of Things" (2010)

In this article, we examine the role played by RFID in enabling user-oriented networked applications. We explain why RFID is seen to be an important building block of the ”Internet of Things” and examine how RFID, assisted by the deployment of NFC devices, is increasingly facilitating user-oriented, Internet-based application architectures. Finally, we look at the high-level security challenges that these user-oriented application architectures will need to address.

Bullous Pemphigoid Antigen: Isolation from Normal Human Skin (1977)

A protein moiety from epidermal PBS-soluble products was isolated by gel filtration (Bio-Gel A-1.5m) and ion exchange chromatography (DEAE-cellulose). This protein (A-1-Epid) was not retarded by DEAE-cellulose in Tris-HCl buffer, 15mM, pH 8.1. By IEP against an antiserum to epidermal antigens, it showed a single cathodal arc. On disc electrophoresis, at low pH (4.3) a single band was apparent. On SDS gels this protein demonstrated two bands, one with a molecular weight of 20,000, and the second with a molecular weight of 9,200. This purified antigen was able to block the staining of the basement membrane zone produced by bullous pemphigoid antibodies on monkey esophagus and normal human skin with the use of indirect immunofluorescence. This study also demonstrates that bullous pemphigoid antigen (A-1-Epid) and a second epidermal protein (A-2-Epid) are present in the PBS-soluble products of human esophageal mucosa, saliva, and urine. These antigens appear to be unrelated with the blood group substances or secretor status of the donors.
Feasibility study of optically coupling RF-power at mm waves (2002)

At mm-wavelengths, ordinary waveguides show considerable attenuation. Corrugated overmoded waveguides have strongly reduced attenuation, while maintaining stability by introducing the well known pattern of passbands and stopbands. Fields either transform to surface waves with very high losses, or concentrate at the center of the waveguide and propagate with very low loss. The latter, are employed to transport RF-power. Considering the field pattern, optical free space coupling to an accelerator structure, is thinkable. We have investigated the coupling mechanism itself, e.g. field leakage and power losses to the outside and designed a device for optical coupling from a corrugated waveguide into a planar muffin-tin structure.

Preliminary results from the CMD-2 detector (1992)

A new general‐purpose detector CMD‐2 (calorimetric magnetic detector) has started experiments at the upgraded e+e− collider VEPP‐2M (collider for electron‐positron beams) at Novosibirsk. During early runs an integrated luminosity of about 400 inverse nanobarns has been collected in the center of mass energy range 400–1030 MeV.
Blast-Induced Color Change in Photonic Crystals Corresponds with Brain Pathology (2011)

A high incidence of blast exposure is a 21st century reality in counter-insurgency warfare. However, thresholds for closed-head blast-induced traumatic brain injury (bTBI) remain unknown. Moreover, without objective information about relative blast exposure, warfighters with bTBI may not receive appropriate medical care and may remain in harm's way. Accordingly, we have engineered a blast injury dosimeter (BID) using a photonic crystalline material that changes color following blast exposure. The photonic crystals are fabricated using SU-8 via multi-beam interference laser lithography. The final BID is similar in appearance to an array of small colored stickers that may be affixed to uniforms or helmets in multiple locations. Although durable under normal conditions, the photonic crystalline micro- and nano-structure are precisely altered by blast to create a color change. These BIDs were evaluated using a rat model of bTBI, for which blast shockwave exposure was generated via a compressed air-driven shock tube. With prototype BID arrays affixed to the animals, we found that BID color changes corresponded with subtle brain pathologies, including neuronal degeneration and reactive astrocytosis. These subtle changes were most notable in the dentate gyrus of the hippocampus, cerebral cortex, and cerebellum. These data demonstrate the feasibility of using a materials-based, power-free colorimetric BID as the first self-contained blast sensor calibrated to correspond with brain pathology.
