Polarization-Insensitive Switchable Frequency-Selective Rasorber/Absorber (2019)

In this paper, a switchable frequency-selective rasorber/absorber structure has been presented based on the reconfigurable characteristic of p-i-n diodes. The proposed design comprises a top resistive layer and a bottom switchable layer, separated by an air spacer. P-i-n diodes are symmetrically mounted across the slots in the bottom topology such that the overall geometry exhibits a switching operation between a low-profile broadband absorber and a rasorber (broadband absorber with narrow transmission band), with the control of the biasing state. An equivalent circuit model has been presented to investigate the operating mechanism of the geometry. Further, the proposed design is polarization-insensitive and angularly stable.
Clinical criteria for diagnosis of Machado‐Joseph disease (1980)

A Portuguese family of non-Azorean origin is described as affected by an autosomal dominant inherited ataxia resembling Machado-Joseph disease. Clinical criteria for diagnosis are proposed, based on a complex clinical picture extending from extrapyramidal signs to peripheral amyotrophy associated with secondary, but more specific, minor features such as progressive external ophthalmoplegia, dystonia, intention fasciculation-like movements of facial and lingual muscles, and bulging eyes. Machado-Joseph disease may be more widespread than previously believed.
Gold processing: Enhancing gold recovery (2010)

The amnion plays important structural and functional roles in the maintenance of pregnancy and the initiation of parturition. Recently, we reported that epidermal growth factor (EGF) activates prostaglandin (PG) production and cell growth in cultured amnion cells. In this study, we showed the expression of EGF, transforming growth factor-alpha (TGF alpha), and EGF receptor protein and messenger ribonucleic acid in amnion cells, using an immunofluorescence technique and the reverse transcription-polymerase chain reaction. Next, we studied the effect of TGF alpha on intracellular Ca2+ mobilization and PGE2 production in amnion cells. TGF alpha induced an increase in the intracellular Ca2+ concentration in amnion cells, and this increase was significantly reduced when the cells were incubated with cobalt chloride (a Ca2+ channel blocker; 2.5 mmol/L) or EGTA (a Ca2+ chelator; 5 mmol/L). TGF alpha enhanced PGE2 production, and this increase was significantly inhibited when the cells were incubated with indomethacin (a cyclooxygenase inhibitor; 10 mumol/L), cobalt chloride (2.5 mmol/L), or EGTA (5 mmol/L). We also investigated the effect of TGF alpha on the growth of cultured human amnion cells by using flow cytometric analysis of the DNA content. TGF alpha induced DNA synthesis by human amnion cells, and indomethacin inhibited the TGF alpha-induced DNA synthesis. These results suggest that 1) EGF/TGF alpha are expressed and produced in amnion cells; 2) these endogenous factors may regulate the proliferation of amnion cells in an autocrine or paracrine manner; and 3) these growth factors may exert their effects via intracellular Ca2+ mobilization and PGE2 production.
Dynamic relocalization of cytosolic type III secretion system components prevents premature protein secretion at low external pH (2021)

Many bacterial pathogens use a type III secretion system (T3SS) to manipulate host cells. Protein secretion by the T3SS injectisome is activated upon contact to any host cell, and it has been unclear how premature secretion is prevented during infection. Here we report that in the gastrointestinal pathogens Yersinia enterocolitica and Shigella flexneri, cytosolic injectisome components are temporarily released from the proximal interface of the injectisome at low external pH, preventing protein secretion in acidic environments, such as the stomach. We show that in Yersinia enterocolitica, low external pH is detected in the periplasm and leads to a partial dissociation of the inner membrane injectisome component SctD, which in turn causes the dissociation of the cytosolic T3SS components. This effect is reversed upon restoration of neutral pH, allowing a fast activation of the T3SS at the native target regions within the host. These findings indicate that the cytosolic components form an adaptive regulatory interface, which regulates T3SS activity in response to environmental conditions.
Optical Kerr effect in glass waveguide (1972)

We have observed light induced birefringence in glass optical waveguide. This effect can be observed at low powers in waveguide because of the high power densities which are maintained over long lengths of guide. This effect is potentially useful as a wide‐band pulse modulator or as a device for switching or measuring the length of picosecond pulses.
Power spectral density analysis of physiological, rest and action tremor in Parkinson’s disease patients treated with deep brain stimulation (2013)

Parkinson's disease patients continuously balance between tremor and tremor suppression or compensation expressed by power shifts between the low frequency band and the tremor frequency band during rest and voluntary motor actions. This balance shows that the pathological tremor is either on or off, with the latter state not resembling that of a healthy subject. Deep brain stimulation can reverse the balance thereby either switching tremor on or off.
Associations between childhood adversity and daily suppression and avoidance in response to stress in adulthood: can neurobiological sensitivity help explain this relationship? (2016)

Childhood adversity may predispose individuals with high neurobiological sensitivity to a lifetime of maladaptive coping.
Femtosecond dynamics of the laser-induced solid-to-liquid phase transition in aluminum (2007)

We present femtosecond time-resolved broadband measurements of the reflectivity of aluminum during the laser-induced solid-to-liquid phase transition. Our experiments show that this transition is a thermal process, settling an existing controversy.
Ultraefficient homogeneous catalyst for the CO 2 -to-CO electrochemical conversion (2014)

A very efficient electrogenerated Fe(0) porphyrin catalyst was obtained by substituting in tetraphenylporphyrin two of the opposite phenyl rings by ortho-, ortho'-phenol groups while the other two are perfluorinated. It proves to be an excellent catalyst of the CO2-to-CO conversion as to selectivity (the CO faradaic yield is nearly quantitative), overpotential, and turnover frequency. Benchmarking with other catalysts, through catalytic Tafel plots, shows that it is the most efficient, to the best of our knowledge, homogeneous molecular catalyst of the CO2-to-CO conversion at present. Comparison with another Fe(0) tetraphenylporphyrin bearing eight ortho-, ortho'-phenol functionalities launches a general strategy where changes in substituents will be designed so as to optimize the operational combination of all catalyst elements of merit.

Intramolecular dynamics of [Rh4(CO)6(μ-PPh2)4] in solution (2002)

A 103Rh, 31P and 13C NMR study of [Rh4(CO)6(μ-PPh2)4] in CD2Cl2 indicates that the strongly bonded, bridging, anionic ligand PPh2− takes part in the site exchange of the carbonyl ligands and is actually mobile about the metallic surface of this cluster compound.
2.5D Clip-Surfaces for Technical Visualization (2013)

The concept of clipping planes is well known in computer graphics and can be used to create cut-away views. But clipping&#13;\nagainst just analytical defined planes is not always suitable for communicating every aspect of such visualization. For example,&#13;\nin hand-drawn technical illustrations, artists tend to communicate the difference between a cut and a model feature by using&#13;\nnon-regular, sketchy cut lines instead of straight ones. To enable this functionality in computer graphics, this paper presents a&#13;\ntechnique for applying 2.5D clip-surfaces in real-time. Therefore, the clip plane equation is extended with an additional offset&#13;\nmap, which can be represented by a texture map that contains height values. Clipping is then performed by varying the clip&#13;\nplane equation with respect to such an offset map. Further, a capping technique is proposed that enables the rendering of caps&#13;\nonto the clipped area to convey the impression of solid material. It avoids a re-meshing of a solid polygonal mesh after clipping&#13;\nis performed. Our approach is pixel precise, applicable in real-time, and takes fully advantage of graphics accelerators.
A Fully Functional Extreme Environment SiC Wireless Temperature Sensing System (2011)

Researchers at Arkansas Power Electronics International, Inc. (APEI, Inc.) have designed and developed a patent pending Silicon Carbide (SiC) wireless temperature sensing system that is capable of operation under extreme temperature and mechanical loads, such as inside a gas turbine engine. High operating temperatures and centrifugal forces in the tens of thousands within the region of the gas turbine engine where the circuits are to be located, exceed the capability of Silicon-on-Insulator (SOI) integrated circuits. The system is designed to be non-intrusively embedded within the turbine engine to provide real-time health monitoring of critical turbine engine components. The SiC based wireless temperature sensing system is designed in conjunction with a high temperature thermocouple to acquire the temperature information on turbine blades or other components inside turbine engine. It has been verified through high temperature laboratory testing, up to the desired temperature level. The combination of this extreme temperature wireless telemetry technology and integrated harsh environment sensors will allow for specific in-situ maintenance of power generation and aircraft turbines during field operation. This combination can also be applied to many other industries that require extreme environment monitoring and maintenance, one example would be nuclear reactors. This form of preventative maintenance may help to reduce maintenance cost, increase operational safety, and prevent possible catastrophic failures.
A nearly-mlogn time solver for SDD linear systems (2011)

We present an improved algorithm for solving symmetrically diagonally dominant linear systems. On input of an $n\times n$ symmetric diagonally dominant matrix $A$ with $m$ non-zero entries and a vector $b$ such that $A\bar{x} = b$ for some (unknown) vector $\bar{x}$, our algorithm computes a vector $x$ such that $||{x}-\bar{x}||_A &lt; ε||\bar{x}||_A $ {$||\cdot||_A$ denotes the A-norm} in time $${\tilde O}(m\log n \log (1/ε)).$$ The solver utilizes in a standard way a `preconditioning' chain of progressively sparser graphs. To claim the faster running time we make a two-fold improvement in the algorithm for constructing the chain. The new chain exploits previously unknown properties of the graph sparsification algorithm given in [Koutis,Miller,Peng, FOCS 2010], allowing for stronger preconditioning properties. We also present an algorithm of independent interest that constructs nearly-tight low-stretch spanning trees in time $\tilde{O}(m\log{n})$, a factor of $O(\log{n})$ faster than the algorithm in [Abraham,Bartal,Neiman, FOCS 2008]. This speedup directly reflects on the construction time of the preconditioning chain.
Neurite outgrowth induced by an endothelial cell mitogen isolated from retina. (1986)

Retina-derived growth factor (RDGF) is a polypeptide growth factor purified from salt extracts of bovine retinas on the basis of its mitogenic activity for capillary endothelial cells (EC) and BALB/c 3T3 cells. RDGF is angiogenic in vivo. We show here that RDGF induces neurite extension by PC12 cells and that this neurite outgrowth is dramatically potentiated by heparin. Neurite formation elicited by RDGF in the presence of heparin cannot be distinguished from that elicited by nerve growth factor (NGF) either by the time course of neurite formation or by the morphology of the neurites at the level of the light microscope. Neurite outgrowth induced by either purified RDGF or by a crude retinal extract is not blocked by antibodies to NGF. Furthermore, neurite outgrowth induced by NGF is not potentiated by heparin and NGF is not mitogenic for capillary EC. Thus, RDGF has profound regulatory effects on cell types of very different embryonic origins. These results indicate that the physiological role for this growth factor may be far more complex than previously suspected and suggest that the formation of neural connections and the process of vascularization may unexpectedly share common regulatory elements.
<title>High-resolution optical fiber reflectometry techniques</title> (1993)

This paper reviews optical reflectometry techniques that are capable of achieving spatial resolutions of less than 1 cm. Advantages and disadvantages of these techniques are discussed. A white light interferometry technique known as optical low-coherence reflectometry is emphasized. This technique has been used to obtain spatial resolutions on the order of tens of microns and reflection sensitivities as low as -148 dB.
Contemporary trends in postchemotherapy retroperitoneal lymph node dissection: Additional procedures and perioperative complications (2015)

Abstract Introduction Postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) is a mainstay in the treatment of men with metastatic testicular cancer. We sought to determine whether trends in the need for additional intraoperative procedures and development of perioperative complications have changed over time. Methods Patients undergoing PC-RPLND from 2003 to 2011 were identified in the Indiana University Testis Cancer Database. Trends in the incidence of perioperative complications and additional procedures were assessed over time using regression tests of trend. Complications were classified according to the modified Clavien system. Univariable and multivariable logistic regression was used to determine factors associated with undergoing additional procedures. Results After exclusion criteria, 755 patients were included in the final study cohort. The incidence of additional procedures at PC-RPLND was 22.1% (167 of 755). The rate of additional procedures per year ranged from 17% to 30%, with no significant trend in any direction ( P trend = 0.66). After adjusting for covariates, preoperative retroperitoneal (RP) mass size, elevated markers, and RP pathology remained significantly associated with the odds of an additional procedure. RP mass size of>10 cm was the strongest predictor (odds ratio = 7.2, 95% CI: 2.6–19.5). Overall, the incidence of perioperative complications was 3.7% (28 of 755). The rate of perioperative complications per year ranged from 0% to 7.3% with no significant trend in any direction ( P trend = 0.06). Conclusion The incidence of perioperative complications is low with no significant trend over the last decade. A substantial number of patients require additional intraoperative procedures during PC-RPLND, which has remained stable at our institution over time.
Life-saving Administration of Fibrinogen to a Case of APL with Acquired Afibrinogenemia due to Disseminated Intravascular Coagulation (1993)

A female patient with acute promyelocytic leukemia and severe bleeding tendency with acquired afibrinogenemia is described. On admission, her plasma fibrinogen was markedly decreased beyond the range of measurement (<10mg/dl). Although disseminated intravascular coagulation existed undoubtedly, the low circulating plasminogen and α 2-plasmin inhibitor, and the presence of plasmin-α 2 plasmin inhibitor complex suggested that the excessive fibrinolysis probably resulted from the liberation of plasminogen activator from the leukemic promyelocytes. To prevent lethal hemorrhage undergoing induction chemotherapy, we administered fibrinogen (5g/day) added to heparin, FUT-175, FFP and platelet transfusion. With these treatments, hypercoagulopathy and increased fibrinolytic state were well controlled to the extent that she did not have overt bleeding tendencies. Although the fibrinogen preparations always carry the risk of causing viral hepatitis, we believe the value of intensive supportive therapy including fibrinogen preparations to prevent the early death for same pathogenesis of severe hypofibrinogenemia.
Hyperimmune Response to a Protein and a Polypeptide Antigen Coated on Pneumococcus R36A (1972)

Abstract Bacterial stimulation of the immune response is a well known but incompletely understood phenomenon (1). The most successful method used to enhance the immunogenicity of protein and polypeptide antigens has been the use of complete Freund's adjuvant. However, the levels of antibody generally produced in rabbits are far below those reported for carbohydrate antigens when they are part of a formalinized suspension of whole bacteria (vaccine). Intensive intravenous (i.v.) immunization of rabbits with either streptococcal or pneumococcal vaccines often results in levels of 5 to 20 mg of antibody/ml serum which is directed mainly against the surface polysaccharides (2–4). An explanation for this vaccine effect is that the bacterial cell serves as the “carrier” for bacterial polysaccharide which can be considered a hapten attached to the bacterial surface. We have examined the possibility that a bacterial cell might serve as a nonspecific carrier for antigens adsorbed onto the cell surface. This was accomplished by coating the positively charged synthetic polymer poly (-γ-2-N-morpholinylethyl- l-glutamamide) (PAMEG) onto a rough strain of Pneumococcus designated R36A. After the first course of immunization, the levels of antibody obtained were 1 to 3 mg/ml serum, and after the second course, one animal had 16 mg of anti-PAMEG antibody/ml serum (5).
Prototype of magnetic energy harvesting device as a 3.3 V battery (2017)

The purpose of this study is to obtain power for driving sensors using the magnetic energy harvesting. The magnetic energy harvesting device is constituted with a coil, a full-wave rectifier circuit and a DC-DC step-down converter. In this paper, this device was evaluated to obtain a DC output voltage of 3.3 V. Additionary, a target power for driving sensors was set to 90 mW. As an evaluated result, an output voltage of 3.3 V could be obtained. Especially, a output power of 104 mW harvested at connected a load resistance of 100 Ω.
Now Playing: DVD Purchasing for a Multilocation Rental Firm (2010)

This paper studies the problem of purchasing and allocating copies of movies to multiple stores of a movie rental chain. A unique characteristic of this problem is the return process of rented movies. We formulate this problem for new movies as a newsvendor-like problem with multiple rental opportunities for each copy. We provide demand and return forecasts at the store-day level based on comparable movies. We estimate the parameters of various demand and return models using an iterative maximum-likelihood estimation and Bayesian estimation via Markov chain Monte Carlo simulation. Test results on data from a large movie rental firm reveal systematic underbuying of movies purchased through revenue-sharing contracts and overbuying of movies purchased through standard (nonrevenue-sharing) ones. For the movies considered, our model estimates an increase in the average profit per title for new movies by 15.5% and 2.5% for revenue sharing and standard titles, respectively. We discuss the implications of revenue sharing on the profitability of the rental firm.
Bubble Formation and Behaviour Under Hypergravity Conditions (2010)

Bubble formation and behaviour have been studied over decades, but the complex two-phase flow phenomena involved are still not fully understood. In view of the importance of two-phase flow processes in a broad range of industrial applications, such as the chemical process industry, food industry and aerospace applications, it is crucial to obtain a detailed understanding of single and multiple bubble dynamics. Gravity plays an important role in bubble formation and behaviour. Several studies have been conducted on single bubble formation under microgravity conditions, but the effects of gravitational accelerations much larger than on Earth have not been previously documented. In order to gain a full understanding of the effect of gravity on the bubble dynamics and in view of industrial applications, particularly aerospace applications, it is essential to examine bubble formation and behaviour under hypergravity conditions. Bubble formation and behaviour at the surface of a porous material and at a nozzle were investigated at hypergravity levels of 1–20g using the Large Diameter Centrifuge (LDC) at ESA/ESTEC. The formation of air bubbles through a porous filter into a water column was recorded under hypergravity conditions and the obtained data were analysed qualitatively. A decrease in bubble size and an increase in bubble formation frequency with increasing hypergravity levels could be clearly observed. Data for the experiments on air and oil bubble formation at a nozzle into a water column were recorded under hypergravity conditions using a high speed camera (for different nozzle sizes and air/oil flow rates). For the recorded data from the experiments on air and oil bubble formation at a nozzle, a decrease in bubble size and an increase in bubble formation frequency with increasing gravitational acceleration could be observed qualitatively. Quantitative analysis of the data obtained for the experiments on air bubble formation at a nozzle clearly showed a decrease in average bubble diameter with increasing hypergravity levels. The effect of the nozzle diameter on the bubble size was shown to be small and the bubble diameter was larger for higher flow rates.
