High-Performance Organic Photovoltaics Incorporating an Active Layer with a Few Nanometer-Thick Third-Component Layer on a Binary Blend Layer (2021)

In this paper, a universal approach toward constructing a new bilayer device architecture, a few-nanometer-thick third-component layer on a bulk-heterojunction (BHJ) binary blend layer, has been demonstrated in two different state-of-the-art organic photovoltaic (OPV) systems. Through a careful selection of a third component, the power conversion efficiency (PCE) of the device based on PM6/Y6/layered PTQ10 layered third-component structure was 16.8%, being higher than those of corresponding devices incorporating the PM6/Y6/PTQ10 BHJ ternary blend (16.1%) and the PM6/Y6 BHJ binary blend (15.5%). Also, the device featuring PM7/Y1-4F/layered PTQ10 layered third-component structure gave a PCE of 15.2%, which is higher than the PCEs of the devices incorporating the PM7/Y1-4F/PTQ10 BHJ ternary blend and the PM7/Y1-4F BHJ binary blend (14.2 and 14.0%, respectively). These enhancements in PCE based on layered third-component structure can be attributed to improvements in the charge separation and charge collection abilities. This simple concept of the layered third-component structure appears to have great promise for achieving high-performance OPVs.
Resonance frequencies of lipid-shelled microbubbles in the regime of nonlinear oscillations (2020)

Knowledge of resonant frequencies of contrast microbubbles is important for the optimization of ultrasound contrast imaging and therapeutic techniques. To date, however, there are estimates of resonance frequencies of contrast microbubbles only for the regime of linear oscillation. The present paper proposes an approach for evaluating resonance frequencies of contrast agent microbubbles in the regime of nonlinear oscillation. The approach is based on the calculation of the time-averaged oscillation power of the radial bubble oscillation. The proposed procedure was verified for free bubbles in the frequency range 1–4 MHz and then applied to lipid-shelled microbubbles insonified with a single 20-cycle acoustic pulse at two values of the acoustic pressure amplitude, 100 kPa and 200 kPa, and at four frequencies: 1.5, 2.0, 2.5, and 3.0 MHz. It is shown that, as the acoustic pressure amplitude is increased, the resonance frequency of a lipid-shelled microbubble tends to decrease in comparison with its linear resonance frequency. Analysis of existing shell models reveals that models that treat the lipid shell as a linear viscoelastic solid appear may be challenged to provide the observed tendency in the behavior of the resonance frequency at increasing acoustic pressure. The conclusion is drawn that the further development of shell models could be improved by the consideration of nonlinear rheological laws.
The adjunctive use of Angio-Seal in femoral vascular closure following percutaneous transcatheter aortic valve replacement (2016)

The adjunctive Angio-Seal technique to augment the dual PP pre-close strategy for patients undergoing percutaneous femoral closure following TAVR is feasible and safe and may be considered as a bail-out or an alternative strategy when the dual PP closure technique fails to obtain complete haemostasis.

Picosecond Spectroscopy of Excited States in Transition-Metal-Ion Doped New Laser Materials (1993)

Saturation of absorption and relaxation processes in excited states of tetrahedral Cr4+ in garnets and forsterite and Co2+ in GSGG are investigated. An upper limit for intra 3T2 state vibrational relaxation time and absorption cross section for 3A2-3T2 transition of tetrahedral Cr4+ and nonradiative life-time of 4T1 (4P) and 4T1(4F) excited states of Co2+ are estimated. Q-switched and ultrashort pulses are realized in neodymium lasers using chromium doped crystals as the saturable absorbers .
Identification of a new‐to‐science cyanobacterium, Toxifilum mysidocida gen. nov. & sp. nov. (Cyanobacteria, Cyanophyceae) (2016)

Cyanobacteria occupy many niches within terrestrial, planktonic, and benthic habitats. The diversity of habitats colonized, similarity of morphology, and phenotypic plasticity all contribute to the difficulty of cyanobacterial identification. An unknown marine filamentous cyanobacterium was isolated from an aquatic animal rearing facility having mysid mortality events. The cyanobacterium originated from Corpus Christi Bay, TX. Filaments are rarely solitary, benthic mat forming, unbranched, and narrowing at the ends. Cells are 2.1 × 3.1 μm (width × length). Thylakoids are peripherally arranged on the outer third of the cell; cyanophycin granules and polyphosphate bodies are present. Molecular phylogenetic analysis in addition to morphology (transmission electron microscopy and scanning electron microscopy) and chemical composition all confirm it as a new genus and species we name Toxifilum mysidocida. At least one identified Leptolyngbya appears (based on genetic evidence and TEM) to belong to this new genus.
Gastrointestinal: Diphyllobothriasis (2007)

A 34-year-old Japanese man whose favorite food was salmon sushi was referred for evaluation because of abdominal discomfort. Colonoscopy was performed. Surprisingly, we identified a long, noodle-like, mobile worm extending from the terminal ileum to the anus (1, 2). The worm had a pale color and fragments were removed from the colon by gentle traction with a retrieval basket. The worm was identified as Diphyllobothrium latum. The patient was treated with 600 mg of praziquantel. D. latum is the longest tapeworm in humans and is usually located in the lower jejunum or upper ileum. A typical worm is 4–15 m in length and 10–20 mm in width. It has an elongated scolex with two sucking grooves, a thin neck and 3000–4000 proglottids. The latter produce up to 1 million eggs each day that are excreted into the intestinal lumen and passed in feces. The life-cycle is relatively complex and involves larval stages that develop in water and in two intermediate hosts, fresh water crustaceans and fish. Humans are infected by eating raw fish. As the developing larvae have particular ecologic requirements, human infections are largely restricted to Northern Europe, Canada and Alaska. Tapeworms can be single or multiple and may result in symptoms such as fatigue, weakness, parasthesia, diarrhea and craving for salt. A minority of patients (2%) develop vitamin B12 deficiency, apparently because of vitamin B12 absorption by the adult worms as well as interference with the ileal absorption of cobalamins. The diagnosis of D. latum is usually made by the detection of eggs in feces and patients can be treated with a variety of drugs including praziquantel. The detection of adult worms at the time of colonoscopy appears to be unusual. The infective larval forms in fish (plerocercoids), can be readily killed by cooking fish at 55°C for 5 min or by freezing for 8–72 h. Contributed by
Actividad proteolítica asociada a la pared celular (1994)

El fluido extracelular (EF), conteniendo proteínas solubles y unidas iónicamente a la pared celular, fue extraído de hipocótilos etiolados de poroto. Se observó que, durante el alargamiento de los hipocótilos, disminuyó la cantidad de proteínas y se produjeron cambios significativos en el patrón polipeptídico del EF, sugiriendo la presencia de proteasas asociadas a la pared celular. Se determinó a diferentes pHs la actividad proteolítica presente en el mismo, observándose una actividad endopeptidasa ácida, con un máximo a pH 4,5. Dicha endopeptidasa fue aislada del resto de las proteínas presentes en el EF por cromatografía de afinidad, en un gel de hemoglobina-agarosa. La enzima aislada presentó alta estabilidad térmica y temporal, además de dependencia de cofactores metálicos. La endopeptidasa parece ser una enzima monomérica, con una masa molecular aproximada de 52 kDa, que tiene como sustrato a numerosas proteínas extracelulares. La actividad endopeptidasa aumentó durante el crecimiento de los hipocótilos, hasta alcanzar su máximo valor durante la fase exponencial de elongación. Posteriormente, la actividad disminuyó, sugiriendo alguna función en la regulación del alargamiento.
Abstract 5245: A network of microRNAs contolled by oncogenic B-Raf signaling in melanoma cells (2014)

Abstract Constitutive activation of the B-Raf/MKK/ERK signaling pathway a result of B-Raf activating mutations is a hallmark of over two-thirds of melanomas. The most prevalent mutation, B-RafV600E, promotes cancer cell behavior through mechanisms which are still incompletely defined. We utilized microRNA (miRNA) microarray profiling to identify a network of more than 20 miRNAs deregulated by B-Raf/MKK/ERK in melanoma cells, the majority of which modulate expression of key cancer regulatory genes and functions. Importantly, miRNAs within the network converge on protein regulation and cancer phenotypes, suggesting that these miRNAs might function combinatorially. Additionally, by altering functional levels of these miRNAs in cells with miRNA mimics and inhibitors we demonstrate that miRNAs augment effects on protein repression and cell invasion when co-expressed, and we also observe gene-specific latency and interference effects between miRNAs. Thus, B-Raf/MKK/ERK controls key aspects of cancer cell behavior and gene expression by modulating a network of miRNAs with cross-regulatory functions. The findings highlight the potential for complex interactions between coordinately regulated miRNAs within a gene expression network. Citation Format: Kasey L. Couts, Emily M. Anderson, Maren M.

Gastrointestinal leukocytoclastic vasculitis: An adverse effect of sirolimus (2005)

An 18-yr-old Hispanic female with end-stage renal disease secondary to chronic glomerulonephritis of unknown etiology underwent cadaveric renal transplantation. She was placed on a steroid-free protocol with tacrolimus and mycophenolate mofetil (MMF) for maintenance immunosuppression. Approximately 8 months post-transplantation, MMF was replaced by sirolimus (SRL) because of persistent leukopenia. Four months after the initiation of SRL, the patient began to experience chronic, constant periumbilical abdominal pain in the absence of vomiting, diarrhea or melena. Esophagogastroduodenoscopy and CT scans revealed significant diffuse mucosal thickening of the antrum, duodenum, and jejunum; leukocytoclastic vasculitis was identified on antral biopsy. A repeat biopsy after reduction of sirolimus dose by 50% over 6 months showed mild chronic inflammation of stomach and duodenum with some improvement in abdominal pain. Discontinuation of SRL and replacement with low dose MMF resulted in complete resolution of pain and normalization of gastrointestinal anatomy by imaging studies within 2 months. In light of this report, drug-induced leukocytoclastic vasculitis caused by SRL should be considered in the differential diagnosis of chronic abdominal pain in a patient with organ transplantation.
Influence of Oil Volume Upon Operation and Performance of Screw Machines With High Built-In Volume Ratio (2019)

Abstract A performance calculation of a screw compressors with increased built-in volume ratio was performed and presented in this paper to establish how increased built-in volume ratio influences compressor efficiency. It is known that screw compressors have limited built-in volume ratio which is determined by their standard discharge port size and position close to the bores cusp. However, if the discharge port size is reduced beyond its cusp position, the screw machine built-in volume may be increased. In such a case, influence of the oil volume in the air-oil mixture of oil-flooded compressors increases the machine built-in volume further. A performance improvement achieved if the built-in volume ratio is doubled in comparison with the standard port during the machine operation at high pressure ratio of more than 20, is up to 26% in the specific power and adiabatic efficiency. This confirms superiority of the reduced size high pressure port for compressors which operate at high pressure ratio.
A pneumatically controllable flexible and polymeric microfluidic valve fabricated viain situdevelopment (2005)

In this paper, we have developed a pneumatically controllable polydimethylsiloxane (PDMS)-based microfluidic valve. This valve regulates 'On/Off' of flow using the thick centered membrane. To integrate the freely moving thick centered membrane, regional bonding of the PDMS layer is required. Here, we integrated such a membrane employing a water soluble mask as a regional bonding method, and the mask was washed out by flowing distilled water. The fabricated valve showed good 'On/Off' operations in accordance with the applied pneumatic pressure source. The flow rate could be regulated by the pressure applied to the inlet (regulated by changes in the height of the water column) and the compression-/vacuum-period ratio (this means the ratio of 'On' and 'Off' periods in each cycle) in the range of a few microliters per minute. For the durability test, ten valves were operated simultaneously one million times, and no failed valves were observed.

Dempster and M. Kallio, IIASA CP-81-S1) contains a bibliography covering North American and Western European publications. This bibliography is a supplement which covers Eastern European work on large-scale linear programming. \n\nAs some important work may still be missing, further contributions (with English translations of titles published in other languages) are most welcome. Such contributions should be sent to H. Gasking at IIASA, where a computerized bibliography is maintained. Revised versions will be issued from time to time.
Advancements in Actuated Musical Instruments (2011)

This article presents recent developments in actuated musical instruments created by the authors, who also describe an ecosystemic model of actuated performance activities that blur traditional boundaries between the physical and virtual elements of musical interfaces. Actuated musical instruments are physical instruments that have been endowed with virtual qualities controlled by a computer in real-time but which are nevertheless tangible . These instruments provide intuitive and engaging new forms of interaction. They are different from traditional (acoustic) and fully automated (robotic) instruments in that they produce sound via vibrating element(s) that are co-manipulated by humans and electromechanical systems. We examine the possibilities that arise when such instruments are played in different performative environments and music-making scenarios, and we postulate that such designs may give rise to new methods of musical performance. The Haptic Drum, the Feedback Resonance Guitar, the Electromagnetically Prepared Piano, the Overtone Fiddle and Teleoperation with Robothands are described, along with musical examples and reflections on the emergent properties of the performance ecologies that these instruments enable. We look at some of the conceptual and perceptual issues introduced by actuated musical instruments, and finally we propose some directions in which such research may be headed in the future.
Immunological Stability of Calcitonin in Plasma (1972)

Relative rates of decline in the concentration of immunoassayable calcitonin from several species were compared by serial specific radioimmunoassay measurements during incubations in vitro in plasmas or serums obtained from a number of different animals. The immunological activities of porcine, bovine and ovine calcitonins were rapidly inactivated (50% inactivation in 2-3 hr at 25 C) while salmon and human calcitonins, structurally distinct forms of calcitonin, were relatively stable (50% inactivation in 30 or more hr at 25 C). That the inactivation of calcitonin in plasma, in vitro, may be due to an enzymatic process was suggested by: 1) dependence of rate of inactivation upon temperature, pH and amount of plasma, 2) prevention of inactivation by prior heating of plasma at 56 C for 30 min, and 3) gel filtration analysis showing that loss of calcitonin immunoreactivity correlates with the appearance of smaller fragments of the hormonal peptide. Primary structural difference among the calcitonins appear to determine their susceptibility to degradation in vitro. The findings have numerous practical implications in the storage, treatment and assay of plasma samples containing calcitonin. (Endocrinology90: 952, 1972)
Embryo‐derived teratocarcinoma II. Teratocarcinogenesis depends on the type of embryonic graft (1980)

Early post-implantation mouse embryos or their embryonic and extraembryonic portions were transplanted under the kidney capsule of adult isogenic recipients in order to test the tumor-producing potential of various grafts and to establish the optimal conditions for teratocarcinoma production. The highest yield of malignant tumors was obtained from 7-day embryos transplanted in toto. Severing the extraembryonic portion of 7-day egg cylinders prior to transplantation of the embryonic part reduced the number of teratocarcinomas to values comparable with those obtained from transplanted 6-day embryos. The extraembryonic portion of 7-day embryos produced no tumors. These data suggest that extraembryonic portions of the 7-day egg cylinder do not have tumorigenic potential alone, but may increase the yield of teratocarcinomas from the embryonic portion of the egg cylinder.
A population‐based competing‐risks analysis of the survival of patients treated with radical cystectomy for bladder cancer (2010)

The current study provides a valuable graphical aid for prediction of cancer-specific and other-cause mortality according to disease stage and patient age. It can help clinicians to better stratify the risk-benefit ratio of radical cystectomy. Hopefully, these findings will be considered in treatment decision making and during informed consent before radical cystectomy.
Tympanic membrane surface motions in forward and reverse middle ear transmissions (2019)

Characterization of Tympanic Membrane (TM) surface motions with forward and reverse stimulation is important to understanding how the TM transduces acoustical and mechanical energy in both directions. In this paper, stroboscopic opto-electronic holography is used to quantify motions of the entire TM surface induced by forward sound and reverse mechanical stimulation in human cadaveric ears from 0.25 to 18.4 kHz. The forward sound stimulus was coupled to an anatomically realistic artificial ear canal that allowed optical access to the entire TM surface, and the reverse mechanical stimulus was applied to the body of the incus by a piezo-electric stimulator. The results show clear differences in TM surface motions evoked by the two stimuli. In the forward case, TM motion is dominated by standing-wave-like modal motions that are consistent with a relatively uniform sound-pressure load over the entire TM surface. With reverse mechanical stimulation, the TM surface shows more traveling waves, consistent with a localized mechanical drive applied to the manubrium embedded in the TM. With both stimuli, the manubrium moves less than the rest of the TM, consistent with the TM acting like a compliant membrane rather than a stiff diaphragm, and also consistent with catenary behavior due to the TM's curved shape.
Direct Surface‐Enhanced Raman Scattering Analysis of DNA Duplexes (2014)

Abstract The exploration of the genetic information carried by DNA has become a major scientific challenge. Routine DNA analysis, such as PCR, still suffers from important intrinsic limitations. Surface‐enhanced Raman spectroscopy (SERS) has emerged as an outstanding opportunity for the development of DNA analysis, but its application to duplexes (dsDNA) has been largely hampered by reproducibility and/or sensitivity issues. A simple strategy is presented to perform ultrasensitive direct label‐free analysis of unmodified dsDNA with the means of SERS by using positively charged silver colloids. Electrostatic adhesion of DNA promotes nanoparticle aggregation into stable clusters yielding intense and reproducible SERS spectra at nanogram level. As potential applications, we report the quantitative recognition of hybridization events as well as the first examples of SERS recognition of single base mismatches and base methylations (5‐methylated cytosine and N6‐methylated Adenine) in duplexes.
Luminescence efficiency of InGaN multiple-quantum-well ultravioletlight-emitting diodes (2004)

The electroluminescence efficiency of In0.06Ga0.94N∕GaN multiple-quantum-well UV light-emitting diodes (LEDs) with emission wavelength of 400nm has been investigated and compared with blue (470nm) LEDs. Based on their injection current-dependent characteristics under dc and pulsed operation, it can be concluded that carrier overflow is the dominant factor that affects the external quantum efficiency of UVLED before thermal effects take over. It is experimentally shown that increasing the number of quantum wells is necessary to alleviate the carrier overflow issue and improve the luminescence efficiency of the UVLEDs.
