Mass‐Radius Relationships for Solid Exoplanets (2007)

We use new interior models of cold planets to investigate the mass-radius relationships of solid exoplanets, considering planets made primarily of iron, silicates, water, and carbon compounds. We find that the mass-radius relationships for cold terrestrial-mass planets of all compositions we considered follow a generic functional form that is not a simple power law: $\log_{10} R_s = k_1 + 1/3 \log_{10}(M_s) - k_2 M_s^{k_3}$ for up to $M_p \approx 20 M_{\oplus}$, where $M_s$ and $R_s$ are scaled mass and radius values. This functional form arises because the common building blocks of solid planets all have equations of state that are well approximated by a modified polytrope of the form $\rho = \rho_0 + c P^n$. We find that highly detailed planet interior models, including temperature structure and phase changes, are not necessary to derive solid exoplanet bulk composition from mass and radius measurements. For solid exoplanets with no substantial atmosphere we have also found that: with 5% fractional uncertainty in planet mass and radius it is possible to distinguish among planets composed predominantly of iron or silicates or water ice but not more detailed compositions; with $\sim$~5% uncertainty water ice planets with $\gtrsim 25%$ water by mass may be identified; the minimum plausible planet size for a given mass is that of a pure iron planet; and carbon planet mass-radius relationships overlap with those of silicate and water planets due to similar zero-pressure densities and equations of state. We propose a definition of "super Earths'' based on the clear distinction in radii between planets with significant gas envelopes and those without.
System Identification with Perfect Sequence Excitation - Efficient NLMS vs. Inverse Cyclic Convolution. (2014)

Linear transmission systems are often characterized by their impulse responses. A simple and fast approach to acquire these impulse responses is the normalized leastmean-square (NLMS) algorithm in combination with a perfect sequence excitation. It is not only applicable to static impulse response measurements, but has been optimized especially for the tracking of time varying linear systems. In this paper, different implementation strategies of the perfect sequence excited NLMS algorithm, namely the efficient NLMS and the inverse cyclic convolution algorithm, are discussed and compared in terms of performance, complexity, and applicability. As a main result it is shown that for certain conditions all algorithmic variants can be transferred to each other.
[Results and considerations regarding auditory neonatal screening based on the use of transient evoked otoacoustic emission]. (1997)

The authors present a 5-year clinical experience in audiological screening performed at the neonatal center of the Policlinico of Perugia, Italy. The study was performed using an IL088 Otodynamics unit produced by Bray & Kemp. A total of 1328 newborns (2656 ears) were tested on the 4th day of life and during spontaneous sleep. None of the children had any audiological risk factors. The test was repeated one month later for all subjects who lacked Transient Evoked Otoacoustic Emissions and in many cases ABR testing was performed by 3 months of age. The authors present the undoubted advantages of the present method which include the fact that it is a) easy to perform, b) non invasive, c) sensitive and d) effective. They then discuss the main problems which arose during the course of the screening and advance some solutions. For the most part these problems involved the high number of false positives (13.1%) and the high percentage of subjects who were lost to subsequent controls (approximately 6% of the total population). The number of false positives could be reduced by using a linear acoustic stimulation (rather than the non-linear stimulation which is the default parameter for the machine). Such a linear stimulation can improve the signal-to-noise ratio, thus making it possible to adopt a reproducibility index lower than the 70% presently used (however, this brings with it the risk of including a certain number of false negatives). Finally, they discuss the possibility of only retesting those subjects with bilateral lack of TEOAEs, thus reducing the number of check-ups to be performed a month later.
Research on Precast Concrete Structures with BIM Involving Information on Structural Details and Behaviors (2015)

Building information model (BIM) is considered as a promising means to facilitate the application of precast concrete (PC). Ordinary BIMs involve the information on geometry, materials, manufacturing details, quantities and so on, which are determined after designing. However, the component details and mechanical behaviors of PC structures, which are usually ignored in the BIM during designing, could profoundly affect the final structural forms. In this paper, several different precast beam-to-column connections applied in China were modeled as the basic components with BIM software, and similar precast moment-resisting frame models were designed with these connections meeting requirements of building codes. Finally they were compared in terms of quantity and total cost. Conclusions came that it was important to build the structural system library of PC including the information of component details and mechanical behaviors in BIM.
Symmetry Breaking and the Turn-On Fluorescence of Small, Highly Strained Carbon Nanohoops (2019)

[n]Cycloparaphenylenes, or “carbon nanohoops,” are unique conjugated macrocycles with radially oriented p-systems similar to those in carbon nanotubes. The centrosymmetric nature and conformational rigidity of these molecules lead to unusual size-dependent photophysical characteristics. To investigate these effects further and expand the family of possible structures, a new class of related carbon nanohoops with broken symmetry is disclosed. In these structures, referred to as meta[n]cycloparaphenylenes, a single carbon-carbon bond is shifted by one position in order to break the centrosymmetric nature of the parent [n]cycloparaphenylenes. Advantageously, the symmetry breaking leads to bright emission in the smaller nanohoops, which are typically non-fluorescent due to optical selection rules. Moreover, this simple structural manipulation retains one of the most unique features of the nanohoop structures-size dependent emissive properties with relatively large extinction coefficents and quantum yields. Inspired by earlier theoretical work by Tretiak and co-workers, this joint synthetic, photophysical, and theoretical study provides further design principles to manipulate the optical properties of this growing class of molecules with radially oriented p-systems.

Acoustic radiation force on a particle in ultrasonic standing wave fields driven by a piezoelectric plate (2015)

Acoustic radiation forces on a particle or droplet in a liquid have been studied mostly for relative simple acoustic fields such as plane traveling waves, or planar standing waves. In this study, a more complicated acoustic field is considered, namely, the acoustic standing wave field generated by a rectangular piezoelectric plate with finite size. The piezo-electric plate is excited in its thickness mode. A three dimensional model of the vibration of the piezo-electric plate has been developed. The plate is loaded by an acoustic standing wave field in a fluid on one side, and is air backed on the other side. The three-dimensional acoustic standing wave field generated by the piezo-electric plate is calculated. The acoustic radiation force on a particle or droplet can then be calculated using a framework such as developed by Gor’kov or Ilinskii and Zabolotskaya. The theoretical calculations are compared with numerical predictions using a two-dimensional model of the piezo-electric plate and resonator. Finally, experimental results were obtained in a resonator with a one inch acoustic path length and driven by a 2 MHz PZT-8 one inch by one inch piezo-electric plate. Experimental results will be compared with theoretical and numerical predictions.
Splice Modulation Synergizes Cell Cycle Inhibition (2020)

While recognized as a therapeutic target, the spliceosome may offer a robust vector to improve established therapeutics against other protein targets. Here, we describe how modulating the spliceosome using small molecule splice modulators (SPLMs) can prime a cell for sensitivity to a target-specific drug. Using the cell cycle regulators aurora kinase and polo-like kinase as models, this study demonstrates how the combination of SPLM treatment in conjunction with kinase inhibition offers synergy for antitumor activity using reduced, sublethal levels of SPLM and kinase inhibitors. This concept of splice-modulated drug attenuation suggests a possible approach to enhance therapeutic agents that have shown limited applicability due to high toxicity or low efficacy.

Price policy, poverty, and power within rural West African households (2007)

This paper explores the impact of agricultural price policy on poverty in West Africa, a region in which prices are an important tool for raising rural household incomes. A game-theoretic, collective model of household income generation and resource allocation is developed that incorporates three features typical of West African rural households: preference heterogeneity among women and men, individual resource control, and power-mediated bargaining over resource control in the face of changes in households' economic environments. To explore price effects, the model is used to simulate the income impacts of large increases in cotton prices accompanying fast-paced agricultural liberalisation in Burkina Faso in the 1980s. The paper shows that where resources are controlled individually by household members, rather than pooled, Pareto efficiency in income generation does not hold. The impact of agricultural price policy on poverty is mediated by bargaining over resource control within households. Both the relative bargaining power of women and men and the degree of preference heterogeneity between them play fundamental roles in the outcome of such bargaining. The results point to a lower ability of households to take advantage of price incentives and thereby raise their incomes than a unitary household model, in which preferences do not differ and resources are pooled, predicts. They suggest that the effectiveness of price policy in reducing poverty in the region would be enhanced by taking into account the incentive structure within households as well as individual household members' ability to bargain over the benefit and cost streams flowing from price changes.
Next-Generation Multiple Access Based on NOMA With Power Level Modulation (2022)

To cope with the explosive traffic growth expected in next-generation wireless networks, it is necessary to design next-generation multiple access techniques that can provide higher spectral efficiency as well as larger-scale connectivity. As a promising candidate, power-domain non-orthogonal multiple access (NOMA) has been widely studied. In conventional power-domain NOMA, multiple users are multiplexed in the same time and frequency band with different <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">preset</i> power levels, which, however, may limit the spectral efficiency under practical finite alphabet inputs. Inspired by the concept of spatial modulation, we propose to solve this problem by encoding extra information bits into the power levels, and exploiting different signal constellations to help the receiver distinguish between them. To convey this idea, termed power selection (PS)-NOMA, clearly, we consider a simple downlink two-user NOMA system with finite input constellations. Assuming maximum-likelihood detection, we derive closed-form approximate bit error rate (BER) expressions for both users. Moreover, the two-user achievable rate region is also characterized. Simulation results verify the analysis and show that the proposed PS-NOMA can outperform conventional NOMA in terms of BER and achievable rate.
Autopolicy: Automated Traffic Policing for Improved IoT Network Security (2020)

A 2.3Tbps DDoS attack was recently mitigated by Amazon, which is a new record after the 2018 GitHub attack, or the famous 2016 Dyn DNS attack launched from hundreds of thousands of hijacked Internet of Things (IoT) devices. These attacks may disrupt the lives of billions of people worldwide, as we increasingly rely on the Internet. In this paper, we tackle the problem that hijacked IoT devices are often the origin of these attacks. With the goal of protecting the Internet and local networks, we propose Autopolicy: a system that automatically limits the IP traffic bandwidth-and other network resources-available to IoT devices in a particular network. We make use of the fact that devices, such as sensors, cameras, and smart home appliances, rarely need their high-speed network interfaces for normal operation. We present a simple yet flexible architecture for Autopolicy, specifying its functional blocks, message sequences, and general operation in a Software Defined Network. We present the experimental validation results, and release a prototype open source implementation.
[A new bifunctional reagent for the intramolecular crosslinking of insulin (author's transl)]. (1975)

Reaction of bis-[2-(succinimidooxycarbonyloxy)ethyl]sulfone [SO2(Eoc-ONSu)2] with insulin in 1N NaHCO3/dimethylformamide forms NalphaA1,NepsilonA1,NepsilonB29-2,2'-sulfonylbis(ethoxycarbonyl)insulin [SO2(Eoc)2-insulin] in 20 - 35% yield. The product can be purified by partition chromatography. After cleavage of the disulfide bridges, reoxidation in very dilute solution reconstitutes about 60% of the original insulin activity. Cleavage of the crosslinking moiety can be achieved with 0.5N NaOH at 0 degrees C in only a few seconds, rendering a biologically fully active insulin.

Electrocatalytic Fischer–Tropsch Reactions. Formation of Hydrocarbons and Oxygen-Containing Compounds from CO on a Pt Gas Diffusion Electrode (1997)

Abstract Electrocatalytic reduction of CO under high pressure (&amp;lt; 60 atm) using a gas diffusion electrode containing Pt catalyst (Pt-GDE) has been investigated. Acetic acid was formed at a high faradaic efficiency of 32% as a predominant CO reduction product at a constant current density of 200 mA cm−2 under CO 40 atm. Moreover, methane, ethane, ethylene, formaldehyde, acetaldehyde, ethanol, 1-propanol, and allyl alcohol were produced as CO reduction products. The selectivity of the reduction products depends remarkably on electrolysis conditions such as the current density, pressure of CO, and temperature. C2-compounds such as ethylene, ethanol, and acetic acid were preferentially formed at small current densities and/or high CO pressure conditions, whereas methane was predominantly produced at large current densities and/or low CO pressure conditions.

Nonlinear unipolar charge transport in silicon microcontacts (1989)

Contacts between heavily doped and moderately doped n-type silicon deviate drastically from conventional junctions upon shrinkage in size. Their resistance increases with increasing current injection, indicating a dipole of electron pileup and depletion near the resistivity discontinuity. Such microjunctions thus represent not the previously assumed ideal contacts but rather a novel type of Schottky barrier.

Critérios para seleção do intervalo RR no eletrocardiograma para quantificação da arritmia sinusal respiratória (2000)

O sistema nervoso autônomo (SNA) sofre importantes adaptações ao treinamento físico aeróbico e alterações na sua função estão relacionadas à gênese e prognóstico de várias doenças. A variação da freqüência cardíaca em função da respiração constitui fenômeno natural no qual se baseia o teste da arritmia sinusal respiratória (ASR), utilizado para avaliar o funcionamento do ramo parassimpático do SNA sobre o sistema cardiovascular. Calcula-se a ASR através da razão entre o maior intervalo R-R do eletrocardiograma (ECG) durante a expiração (E) e o menor R-R na inspiração (I). Não existe, na literatura, padronização para escolha destes intervalos quando o ECG é registrado durante dois ciclos respiratórios consecutivos. O objetivo deste trabalho é comparar os métodos de escolha desses intervalos, indicando qual o critério que permite melhor avaliação da magnitude da ASR. Cinqüenta e cinco voluntários jovens foram submetidos a dois testes de ASR, sendo cada teste composto por dois ciclos respiratórios consecutivos. Foram então comparados os dois maiores índices E/I obtidos das seguintes maneiras: 1) E e I retirados do mesmo ciclo respiratório (intraciclo); 2) E e I retirados de qualquer um dos ciclos respiratórios (ciclo independente). Os índices E/I ciclo-independentes (1º teste = 1,49 ± 0,03; 2º teste = 1,44 ± 0,03) foram maiores do que os índices E/I obtidos intraciclo [1º teste = 1,44 ± 0,03; 2º teste = 1,41 ± 0,03 (P &lt; 0,001)]. Os índices E/I ciclo-independentes do 1º teste foram maiores do que os do 2º teste (P = 0,04). A utilização de intervalos E e I escolhidos de forma independente do ciclo respiratório onde ocorreram permitiu observação da máxima variação da atividade parassimpática, mostrando a máxima magnitude da ASR. Em adendo, os resultados sugerem uma acomodação do reflexo no 2º teste, tornando desnecessária a realização deste quando o 1º prosseguir sem intercorrências técnicas.
A truncated form of human alpha 1-acid glycoprotein is useful as a molecular tool for insect glycobiology (2018)

N-glycosylation is an important posttranslational modification that results in a variety of biological activities, structural stability, and protein-protein interactions. There are still many mysteries in the structure and function of N-glycans, and detailed elucidation is necessary. Baculovirus expression system (BES) is widely used to produce recombinant glycoproteins, but it is not suitable for clinical use due to differences in N-glycan structure between insects and mammals. It is necessary to develop adequate model glycoproteins for analysis to efficiently alter the insect-type N-glycosylation pathway to human type. The previous research shows the recombinant alpha 1-acid glycoprotein (a1AGP) secreted from silkworm cultured cells or larvae is highly glycosylated and expected to be an excellent research candidate for the glycoprotein analysis expressed by BES. Therefore, we improved the a1AGP to be a better model for studying glycosylation. The modified a1AGP (a1AGPΔ) recombinant protein was successfully expressed and purified by using BES, however, the expression level in silkworm cultured cells and larvae were lower than that of the a1AGP. Subsequently, we confirmed the detailed profile of N-glycan on the a1AGPΔ by LS/MS analysis the N-glycan structure at each glycosylation site. These results indicated that the recombinant a1AGPΔ could be usable as a better model glycoprotein of N-glycosylation research in BES.
