Long-Lived Photoinduced Charge Separation Due to the Inverted Region Effect in 1,6-Bis(phenylethynyl)pyrene−Phenothiazine Dyad (2010)

Photoinduced electron-transfer processes in a 1,6-bis(phenylethynyl)pyrene−phenothaiazine dyad, BPEP−PT, are examined using various techniques. The BPEP singlet excited state is quenched by electron transfer from PT leading to formation of BPEP radical anion and PT radical cation. Rate constants and quantum yields of the PET processes were determined from steady-state and time-resolved fluorescence experiments, and spectroscopic identification of the radical ion products was achieved using picosecond and nanosecond flash photolysis experiments. The charge-separated (CS) state was found to be long-lived but decayed to the BPEP triplet state under the influence of external heavy atom effect. The energy level diagram constructed on the basis of experimental data revealed the existence of the local triplet state below the CS state, yet the CS state did not exhibit any tendency to decay to this level. This showed that hyperfine interaction (HFI) or spin−orbit charge-transfer intersystem crossing (SOCT-ISC) mechanisms are not effective in inducing intersystem crossing in the CS state. It is suggested that absence of SOCT-ISC in the CS state may be a consequence of the total absence of ISC in the parent BPEP chromophore. The only option available to the CS state is a spin-allowed transition to the ground state, and this process is slow because of inverted region effects.
Productivity and Nutritive Values of Different Fractions of Oil Palm (Elaeis guineensis) Frond (2000)

Productivity, nutrient contents, in vitro gas production and in sacco degradability of different fractions and whole OPF were determined to assess the feeding value of OPF as a ruminant feed. An in vivo digestibility trial was also carried out using goat. Freshly harvested OPF was randomly collected, partitioned and weighed. An OPF from 21 years older palm weighed 13.4 kg and the annual fresh matter yield of petiole, leaflet and midrib was 46.5, 11.8 and 3.4 ton/ha, respectively. Leaflet contained 439, 926, 698, 501, 168, 196, 748 and 52 (g/kg) of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose (CE), hemicellulose (HC), total carbohydrate (TC) and non fiber carbohydrate (NFC), respectively. Petiole contained lower (p<0.01) DM, CP and EE contents than leaflet. Organic matter, CE and TC contents were higher (p<0.01) in petiole compared to leaflet. Silica and lignin contents were highest (p<0.01) in midrib followed by leaflet, whole OPF and least in petiole. The Ca, P, Na, K and Mg contents (g/100 g DM) of leaflet were 0.529, 0.182, 0.039, 0.876, and 0.168, respectively. In vitro DM digestibility (g/100 g) at 48 h of leaflet, petiole and midrib was 32.7, 38.7 and 30.2, respectively. The in sacco DM degradation (g/100 g) at 48 h of leaflet was higher than that of whole OPF, petiole and midrib. The in vivo digestibility of DM, OM, CP and ADF of whole OPF was 52, 56, 43 and 26%, respectively. It can be concluded that leaflet is the most nutritious fraction of OPF and midrib is the least. The nutrient content and digestibility of the whole OPF showed that OPF could be an alternative roughage source for ruminant diets.
Flight test of a resident backup software system (1986)

A new fault-tolerant system software concept employing the primary digital computers as host for the backup software portion has been implemented and flight tested in the F-8 digital fly-by-wire airplane. The system was implemented in such a way that essentially no transients occurred in transferring from primary to backup software. This was accomplished without a significant increase in the complexity of the backup software. The primary digital system was frame synchronized, which provided several advantages in implementing the resident backup software system. Since the time of the flight tests, two other flight vehicle programs have made a commitment to incorporate resident backup software similar in nature to the system described in this paper.

IMPOTENCE AFTER RENAL TRANSPLANTATION (1998)

REPLY TO "IMPOTENCE AFTER RENAL TRANSPLANTATION" Dr. Nghiem does not appear to understand the purpose of my article. I am fully aware of the incidence and of the many causes of impotence, which he describes so clearly. I do not claim that division of both internal arteries always causes impotence, although I do believe that it is a major risk factor. I further believe that is not necessary to divide both arteries for transplantation purposes because there are other perfectly adequate ways to revascularize transplanted organs. The article is not about my prejudices, but about what can be regarded as acceptable surgical practice. A court in the United Kingdom recently ruled that to divide both internal iliac arteries was acceptable because there was nothing in the literature to say that it was not. It is not true to say that "the hypogastric artery is almost never used for the transplantation procedure." It is still used quite frequently in live donor transplants, as Dr. Nghiem says, and by some surgeons in cadaveric transplantation. It was therefore my objective to find out if transplant surgeons in the United Kingdom believed that dividing both internal iliac arteries was a risk factor in impotence and whether it is an acceptable thing to do. The "simplistic questionnaire" establishes quite clearly that British transplant surgeons do think that division of both arteries is a risk and that it is not acceptable practice. One hypogastric artery can have its uses in transplantation but not two. Publication of the views currently held by British transplant surgeons should prevent recipients of kidneys being subjected to an unnecessary risk of impotence. If I achieve that objective I am content, and leave Dr. Nghiem to his studies of penile tumescence to evaluate scientifically the extent of the "risk." R.M.R.

A deep learning based approach with adversarial regularization for Doppler weather radar ECHO prediction (2017)

Precipitation nowcasting is an important component for accurate weather modeling and Doppler radar data acts as an important input for nowcasting models. In this work, we propose a deep learning based approach for radar echo states prediction. Our approach uses a hybrid structure of convolutions within Long Short Term Memory recurrent network structure and a discriminator network is added in the loss objective to refine the predictions acting as a regularizer. This models the spatio-temporal nature of the problem explicitly in the neural network. We show that this model can be applied for fine grained short term precipitation prediction with improvement in evaluation metrics as compared to strong baselines. The proposed model improves recall score by 11% compared to without adversarial regularization. Results are presented using usual train, test strategy for the task of echo state prediction and derived precipitation based skill scores on the data from Seattle, WA, USA.
On the Crack Extension in Plates Under Plane Loading and Transverse Shear (1963)

The crack extension in a large plate subjected to general plane loading is examined theoretically and experimentally. It is found that under skew-symmetric plane loading of brittle materials the “sliding” or the crack extension in its own plane does not take place, instead crack grows in the direction approximately 70 deg from the plane of the crack. This is very nearly the direction perpendicular to the maximum tangential stress at the crack tip, which is 70.5 deg. The hypothesis that the crack will grow in the direction perpendicular to the largest tension at the crack tip seems to be verified also by cracked plates under combined tension and shear. In spite of the fact that “sliding” and “tearing” modes of crack extension do not take place in brittle materials it is shown that one can still talk about critical stress intensity factors in plane shear and transverse bending of plates. It is also shown that, in general plane loading, the fracture criterion in terms of stress intensity factors is an ellipse.
Effects of new non‐N‐methyl‐D‐aspartate antagonists on synaptic transmission in the in vitro rat hippocampus. (1989)

1. The effects of new, potent non-N-methyl-D-aspartate (NMDA) receptor antagonists, 6,7-dinitroquinoxaline-2,3-dione (DNQX) and 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX), have been examined using intra- and extracellular recordings in the hippocampal slice preparation. In terms of potency and selectivity, the action of the two blockers was similar and CNQX was used in most experiments. 2. CNQX reduced the responses to ionophoretic applications of the non-NMDA agonists kainate (KAI) and quisqualate (QUIS) with IC50 values of 1.2 and 4.8 microM, respectively. In Mg2+-free solutions responses to NMDA were generally not affected by concentrations of CNQX up to 25 microM. 3. The action of CNQX was only slowly and poorly reversible on washing. Responses to QUIS and KAI were also reversibly reduced by ionophoretic application of CNQX. 4. CNQX blocked the evoked EPSP in CA1 and CA3 neurones with an IC50 of around 2 microM, which is similar to the IC50 for responses to KAI. CNQX was without effect on the passive membrane properties, the afferent volley and paired pulse potentiation. 5. In the presence of CNQX (greater than 5 microM) a small EPSP remained which was largest in CA1 neurones. It was blocked by low concentrations of the NMDA receptor antagonist (+/-)-2-amino-5-phosphonovaleric acid (APV), was markedly enhanced on removing Mg2+ ions from the bathing medium and, in voltage-clamp experiments, showed a potential dependence which is characteristic of the NMDA ionophore. 6. The latency of the APV-sensitive EPSP in CA1 was the same as the CNQX-sensitive EPSP, indicating that NMDA receptors participate in monosynaptic excitation. 7. Feedback and feed-forward inhibition in both area CA1 and CA3 were sensitive to CNQX. There seemed to be two components of the inhibition, both of which appear to be GABAergic since they could be blocked by picrotoxin (PTX), but only one of which was blocked by CNQX. The CNQX-resistant IPSP was not affected by APV. 8. In conclusion, quinoxalinediones have been used to demonstrate that non-NMDA receptors mediate the majority of the EPSP. Additionally, a component of the EPSP in CA1 is mediated by NMDA receptors and is manifested at resting membrane potentials and in the presence of Mg2+.
Study of Human Immunodeficiency Virus Resistance to 2'-3'-Dideoxyinosine and Zidovudine in Sequential Isolates from Pediatric Patients on Long-Term Therapy (1993)

Resistance to zidovudine (3'-azido-3'-deoxythymidine) and 2',3'-dideoxyinosine (ddI) has been reported for human immunodeficiency virus (HIV) isolates from adults, but little is known about these drugs in children. A new micrococulture assay was developed for evaluation of drug susceptibility using single-passage HIV isolates cocultured with peripheral blood mononuclear cells from healthy donors. HIV isolates from children treated with zidovudine or ddI were evaluated to define the emergence of resistance to these antiretroviral agents. Four patients were treated with ddI and 3 with zidovudine for > 15 months. There was a > or = 20-fold decrease in susceptibility to ddI for sequential isolates of HIV recovered from 4 patients treated with ddI for 22-31 months and a 4- to 10-fold decrease in susceptibility to zidovudine in 3 patients. HIV isolates from 3 patients treated with ddI or zidovudine alone showed a minor amount of cross-resistance to the other antiretroviral agent. Results indicate the importance of monitoring antiretroviral drug susceptibility of HIV isolates when assessing clinical deterioration in children treated for > 1 year.
The therapeutic use of metronidazole in anaerobic infection: six years' experience in a London hospital. (1983)

For the past 6 years at St. Thomas' Hospital, metronidazole has been used to treat proven anaerobic infection at a wide variety of sites and of varying clinical severity. Throughout this period, intravenous, oral, and rectal preparations of the drug have been available. Initial experience was predominantly in abdominal sepsis where excellent therapeutic results were obtained and treated patients included many with mixed aerobic/anaerobic infection in whom metronidazole was used alone. Metronidazole also has been used either alone or in combination, most frequently with amoxicillin, to treat many other anaerobic infections: head and neck, pleuropulmonary, genital tract, bone and joint, skin and soft tissue, and cases of fusobacterial septicemia (necrobacillosis). Although, as in pyogenic infection of any etiology, surgical intervention often is required in anaerobic sepsis, there is little doubt of the useful therapeutic role of metronidazole in these patients. Increasing awareness of the wide clinical spectrum of human anaerobic infections has led to increasing therapeutic dependence on metronidazole with as yet little evidence of bacterial resistance.
The Essential Process in a Family of Measurement Models (1984)

Five members of the Rasch family of latent trait models which have appeared more or less independently in the literature are brought together and identified as one model. In addition to sharing the distinguishing characteristic of the dichotomous Rasch model—separable person and item parameters and hence sufficient statistics—all five models share a common algebraic form and have as their basic element the fundamental process defined by Rasch's simple logistic expression. In these models, the sufficient statistics for person and item parameters are counts of events constructed to be indicative of the variable being measured, and the measures they enable are ‘fundamental’.
Neurodegeneration with brain iron accumulation: update on pathogenic mechanisms (2014)

Perturbation of iron distribution is observed in many neurodegenerative disorders, including Alzheimer's and Parkinson's disease, but the comprehension of the metal role in the development and progression of such disorders is still very limited. The combination of more powerful brain imaging techniques and faster genomic DNA sequencing procedures has allowed the description of a set of genetic disorders characterized by a constant and often early accumulation of iron in specific brain regions and the identification of the associated genes; these disorders are now collectively included in the category of neurodegeneration with brain iron accumulation (NBIA). So far 10 different genetic forms have been described but this number is likely to increase in short time. Two forms are linked to mutations in genes directly involved in iron metabolism: neuroferritinopathy, associated to mutations in the FTL gene and aceruloplasminemia, where the ceruloplasmin gene product is defective. In the other forms the connection with iron metabolism is not evident at all and the genetic data let infer the involvement of other pathways: Pank2, Pla2G6, C19orf12, COASY, and FA2H genes seem to be related to lipid metabolism and to mitochondria functioning, WDR45 and ATP13A2 genes are implicated in lysosomal and autophagosome activity, while the C2orf37 gene encodes a nucleolar protein of unknown function. There is much hope in the scientific community that the study of the NBIA forms may provide important insight as to the link between brain iron metabolism and neurodegenerative mechanisms and eventually pave the way for new therapeutic avenues also for the more common neurodegenerative disorders. In this work, we will review the most recent findings in the molecular mechanisms underlining the most common forms of NBIA and analyze their possible link with brain iron metabolism.
Optimal Moth Eye Nanostructure Array on Transparent Glass Towards Broadband Antireflection (2013)

Broadband antireflection (AR) is essential for improving the photocurrent generation of photovoltaic modules or the enhancement of visibility in optical devices. Beyond conventional AR coating methods, moth eye mimicking nanostructures give new directions to enhance broadband antireflection through the selection of geometrical parameters, such as height, periodic distance, shape, and arrangement. This study numerically and experimentally investigates the behavior of light on complex nanostructures designed to mimic the surface of the moth eye with mixed shapes and various arrangements. To obtain broadband AR, we rigorously study the design parameters, such as height, periodic distance, shape, and arrangement, on a transparent quartz substrate. Several kinds of nanopillar arrays are elaborately fabricated including mixed nanostructures comprising pointy and round shapes in ordered and random arrangements via colloidal lithography. The optimal morphology of moth eye nanostructure arrays for broadband antireflection is suggested in view of reflectance and average weight transmittance.
Radiation‐induced crosslinking of polyethylene in the presence of acetylene: A gel fraction, UV‐visible, and ESR spectroscopy study (1993)

Abstract Electron‐spin resonance (ESR) and altraviolet (UV) visible spectroscopic evidence has been found for the formation of diene, triene and tetraene, following the irradiation of polyethylene in the presence of acetylene. The polyenes are formed by a mechanism which is different from that observed under vacuum or with inert gas saturation. The sum of the G (polyene) values obtained by UV spectroscopy is almost half that of initial radical formation. It is concluded that polyene bridges, predominantly diene, form crosslinks between radical pairs. G (X) values determined from gel fraction data, using Saito‐Kang‐Dole theory, are found to be greatly in error and misrepresentative of crosslink changes. © 1993 John Wiley & Sons, Inc.
A new multichannel spatial diversity technique for long-range acoustic communications in shallow water (2002)

A new multichannel spatial diversity technique has been developed for underwater acoustic communications in very shallow waters. This technique combines a novel synchronization method with maximum-likelihood symbol estimation. It was tested with a multichannel Mills-Cross receiver using various numbers of elements. The FAU general purpose acoustic modem source transmitted messages using four types of frequency-hopped multiple-frequency-chirp-keying (FH-MFSK) modulation: 4 hops at 221 coded bits per second (cps), 2 hops at 442 cps, or no hopping at 1172 cps. These types of modulation allowed for robust data transmission in adverse environment. The modem operated between 16 and 32 kHz at 192-dB source level, at ranges from 1 to 5 km in 40 ft of water. Using only four channels of the Mills-Cross receiver array, messages coded at 1172 cps were received with a frame error rate (FER) of 0% at a range of 3 km. In the same four-channel configuration, messages coded at 221 cps were received with no frame error at 5 km. The experimental results matched the performance predictions from the Crepeaus model. This reliable and computation-efficient method can be implemented on new generations of embedded acoustic modems, such as the four-channel FAU acoustic modem, and can provide significant improvements in communication performance.
Pyrrole Chemistry. Part XIII. New Syntheses of 3-Alkylpyrroles (1971)

3-n-Alkylpyrroles are prepared in good yield by a combined Wolff-Kishner reduction and hydrolysis and decarboxylation of 4-acyl-2-pyrrolethiolcarboxylates. Methyl 4-isopropyl-2-pyrrolecarboxylate and 4-t-butyl-2-pyrrolecarbonitrile are prepared by alkylation of methyl 2-pyrrolecarboxylate and 2-pyrrolecarbonitrile respectively. Hydrolysis and decarboxylation of these disubstituted compounds afford the corresponding 3-alkylpyrroles. Mass spectral data for some 1-, 2-, and 3-alkylpyrroles are reported.

En 1977, le PAIGC encore unifie de Guinee-Bissau et du Cap-Vert, le FRELIMO (Mozambique) et le MPLA (Angola) tinrent leurs premiers congres posterieurs a l’independance. Les deux derniers adopterent officiellement le “marxisme-leninisme” en devenant partis et le premier, quoique parti, adopta la “democratie revolutionnaire”. On doit discuter le pourquoi de ces nuances, mais dans un cas comme dans l’autre, il s’est agi d’une forme de nationalisme radical de partis uniques. On peut y ajouter le...

The Effects of Nanometal-Induced Crystallization on the Electrical Characteristics of Bottom-Gate Poly-Si Thin-Film Transistors (2011)

The effects of active layer thickness and device dimensions on nanometal-induced crystallization (nano-MIC) were studied to determine the electrical characteristics of the polycrystalline silicon (poly-Si) thin-film transistors (TFTs) with bottom-gate structures. The nano-MIC poly-Si film was obtained via deposition of a 0.4-nm-thick Ni film on the amorphous silicon layer and subsequent annealing at 550 degrees C for 0.5 to 8 h. The EDS revealed a approximately 0.1% Ni concentration in the poly-Si film. The cross-sectional TEM image shows the vertical-grain growth mechanism, where the bottom side of the grain exhibits a larger crytalline area than the top side. Therefore, the field effect mobility of the bottom-gate poly-Si TFTs increases with increased active-amorphous-silicon (a-Si) thickness. Furthermore, the mobility increases when the device dimensions are scaled down. A mechanism for explaining such phenomenon in relation to the nano-MIC bottom-gate poly-Si TFTs was also proposed.
