Fully Differential Touch Screen Controller with Wide Input Dynamic Range for Thin Displays (2020)

As today's smartphone displays become thinner, the coupling capacitance between the display electrodes and touch screen panel (TSP) electrodes is increasing significantly. The increased capacitance easily introduces time-varying display signals into the TSP, deteriorating the touch performance. In this research, we demonstrate that the maximum peak display noise in the time domain is approximately 30% of the maximum voltage difference of the display grayscale through analysis of the structure and operation of displays. Then, to mitigate display noise, we propose a circuit solution that uses a fully differential charge amplifier with an input dynamic range wider than the maximum peak of the display noise. A test chip was fabricated using a 0.35 μm CMOS process and achieved a signal-to-noise ratio of 41 dB for a 6-mm-diameter metal pillar touch when display pulses with 5-V swing were driven at 100 kHz.
Erfahrungen mit Carticain bei der Anästhesie vor ophthalmologischen Eingriffen (1981)

Bei der Anästhesie für ophthalmologischen Eingriffe mit Carticain 2% und Supra-renin-Zusatz (1:400 000) konnte innerhalb 3–5 Minuten in 99% der Fälle die Akinesie des M. orbicularis oculi bewirkt werden. In 73% der Fälle führte die retrobulbäre Anästhesie innerhalb 20 Minuten zur Paralyse der äußeren Augenmuskeln; bei jedem fünften Patienten war eine Nachinjektion erforderlich. Als Komplikationen traten retrobulbäre Hämatome (1%) und pektanginöse Beschwerden (0,5%) bei vasculär vorgeschädigten Patienten auf.

Experimental<i>Mycobacterium tuberculosis</i>Infection of Cynomolgus Macaques Closely Resembles the Various Manifestations of Human<i>M. tuberculosis</i>Infection (2003)

Nonhuman primates were used to develop an animal model that closely mimics human Mycobacterium tuberculosis infection. Cynomolgus macaques were infected with low doses of virulent M. tuberculosis via bronchoscopic instillation into the lung. All monkeys were successfully infected, based on tuberculin skin test conversion and peripheral immune responses to M. tuberculosis antigens. Progression of infection in the 17 monkeys studied was variable. Active-chronic infection, observed in 50 to 60% of monkeys, was characterized by clear signs of infection or disease on serial thoracic radiographs and in other tests and was typified by eventual progression to advanced disease. Approximately 40% of monkeys did not progress to disease in the 15 to 20 months of study, although they were clearly infected initially. These monkeys had clinical characteristics of latent tuberculosis in humans. Low-dose infection of cynomolgus macaques appears to represent the full spectrum of human M. tuberculosis infection and will be an excellent model for the study of pathogenesis and immunology of this infection. In addition, this model will provide an opportunity to study the latent M. tuberculosis infection observed in approximately 90% of all infected humans.
GPU-ABiSort: optimal parallel sorting on stream architectures (2006)

In this paper, we present a novel approach for parallel sorting on stream processing architectures. It is based on adaptive bitonic sorting. For sorting n values utilizing p stream processor units, this approach achieves the optimal time complexity O((n log n)/p). While this makes our approach competitive with common sequential sorting algorithms not only from a theoretical viewpoint, it is also very fast from a practical viewpoint. This is achieved by using efficient linear stream memory accesses (and by combining the optimal time approach with algorithms optimized for small input sequences). We present an implementation on modern programmable graphics hardware (GPUs). On GPUs, our optimal parallel sorting approach has shown to be remarkably faster than sequential sorting on the CPU, and it is also faster than previous non-optimal sorting approaches on the GPU for sufficiently large input sequences. Because of the excellent scalability of our algorithm with the number of stream processor units p (up to n/log/sup 2/ n or even n/log n units, depending on the stream architecture), our approach profits heavily from the trend of increasing number of fragment processor units on GPUs, so that we can expect further speed improvement with upcoming GPU generations.
Genetic conflicts in genomic imprinting (1998)

The expression pattern of genes in mammals and plants can depend upon the parent from which the gene was inherited, evidence for a mechanism of parent-specific genomic imprinting. Kinship considerations are likely to be important in the natural selection of many such genes, because coefficients of relatedness will usually differ between maternally and paternally derived genes. Three classes of gene are likely to be involved in genomic imprinting: the imprinted genes themselves, trans-acting genes in the parents, which affect the application of the imprint, and trnas-acting genes in the offspring, which recognize and affect the expression of the imprint. We show that coefficients of relatedness will typically differ among these three classes, thus engendering conflicts of interest between Imprinter genes, imprinted genes, and imprint-recognition genes, with probable consequences for the evolution of the imprinting machinery.
Multiple Scattering Calculations for Technology (1971)

A many-flux (discrete ordinate) radiative transfer calculation procedure is described with the goal of making the mathematics easy to learn and use. The major approximation is the neglect of polarization. Emission within the scattering medium is not included, and the formulas are restricted to a scattering medium bounded by parallel planes. The boundary conditions allow for a variety of kinds of illumination, and the surface reflection coefficients at the boundaries of the scattering medium are accurately determined. A comparison is made with the two-flux (Kubelka-Munk) and four-flux calculation methods, and this leads to empirical expressions for the scattering and absorption coefficients in these simple theories, which make them give nearly the same results as exact theories. These empirical expressions provide a very simple method for estimating the absolute reflectance and transmittance of turbid media and greatly increase the utility of the two-flux and four-flux calculation methods. The two-flux equations give excellent results provided the absorption is small compared to scattering and the optical thickness is greater than 5. A comparison with experimental data taken with collimated illumination shows that the four-flux equations give good results at any optical thickness even if the absorption is strong.
On the Depolymerization of Polycaproamide Catalyzed by Phosphoric Acid Under Steam Blowing (1974)

ポリカプアミドの解重合反応により一身プロラクタム(以下ラクタムと略記する)を回収する方法において,過熱水蒸気吹き込み下におけるリン酸を触媒とする解重合反応について検討し,以下の結果を得た。ラクタム生成速度は,反応の最後期を除いて零次反応にしたがって進行し,その速度定数(k)の無触媒項はポリマー末端基濃度([-COOH])に比例し,触媒項は添加リシ愚論([H3PO4])に比例する結果を得,ラクタム生成速度定数(k)は,k=k1[-COOH]+k2[H,PO4]で表わされる。一定触媒量におけるラクタム生成速度定数は,Arrhenius式をよく満足し,無二時の見かけの活性化エネルギーは245 kcal／mol と計算された。ラクタムの最終収率は,ほぼ100%に近いが,反応温度が高い場合には触媒量を多く用い,解重合速度を早めた方が高い収率が得られた。
Low Temperature and Low UV Indexes Correlated with Peaks of Influenza Virus Activity in Northern Europe during 2010–2018 (2019)

With the increasing pace of global warming, it is important to understand the role of meteorological factors in influenza virus (IV) epidemics. In this study, we investigated the impact of temperature, UV index, humidity, wind speed, atmospheric pressure, and precipitation on IV activity in Norway, Sweden, Finland, Estonia, Latvia and Lithuania during 2010⁻2018. Both correlation and machine learning analyses revealed that low temperature and UV indexes were the most predictive meteorological factors for IV epidemics in Northern Europe. Our in vitro experiments confirmed that low temperature and UV radiation preserved IV infectivity. Associations between these meteorological factors and IV activity could improve surveillance and promote development of accurate predictive models for future influenza outbreaks in the region.
Durability of a cardiac valve leaflet made of calf pericardium: Fatigue and energy consumption (2006)

We studied the mechanical behavior of membranes of calf pericardium, similar to those employed in prosthetic valve leaflets, when subjected to tensile fatigue. The objective was to assess its durability, as a fundamental property of cardiac bioprosthesis, and analyze the energy consumption. For this purpose, the authors built a hydraulic simulator to subject a spherical valve leaflet made of calf pericardium to cyclic stress mimicking cardiac function. A total of 522 assays were performed in 40 samples, subjected to cyclic pressures greater than 6 atm, and 482 subjected to pressures ranging between 2 and 6 atm. The mathematical expression that establishes the relationship between the pressure exerted and the frequency was obtained. If we assume that the function is continuous, this equation provides the range of fatigue tolerated for a given number of cycles. Using the optimal values (the five highest values per series), the expression was found to be y = 9.95x(-0 1214) (R(2) = 0.955), where x represents the frequency in cycles per second and y the pressure in atmospheres. In addition, we established the mathematical relationship between the energy consumed and the frequency, which was a function of the pressure exerted, regardless of the region or zone from which the samples had been obtained. The methods of manual and morphology-based selection employed produced widely dispersed results. When a mechanical criterion was included, the similarity in the energy consumed during fatigue testing markedly improved the correlation, with a coefficient of determination between paired samples of R(2) = 0.7477. A mechanical criterion, such as energy consumption, can help to improve sample selection and produce more consistent results. Finally, we obtained the mathematical expression that relates the energy consumed to the pressure exerted and the number of cycles per second to which the valve leaflet was subjected. This procedure enables us to establish the limit to the energy that a biomaterial can consume over a period of time during which it is subjected to a working pressure and, thus, calculate more precisely its durability.
Online anonymity for personalized web services (2009)

To receive personalized web services, the user has to provide personal information and preferences, in addition to the query itself, to the web service. However, detailed personal information could identify the sender of sensitive queries, thus compromise user privacy. We propose the notion of online anonymity to enable users to issue personalized queries to an untrusted web service while with their anonymity preserved. The challenge for providing online anonymity is dealing with unknown and dynamic web users who can get online and offline at any time. We define this problem, discuss its implications and differences from the problems in the literature, and propose a solution.

A high-performance SIMD floating point unit for BlueGene/L: architecture, compilation, and algorithm design (2004)

We describe the design, implementation, and evaluation of a dual-issue SIMD-like extension of the PowerPC 440 floating-point unit (FPU) core. This extended FPU is targeted at both IBM's massively parallel BlueGene/L machine as well as more pervasive embedded platforms. It has several novel features, such as a computational crossbar and cross-load/store instructions, which enhance the performance of numerical codes. We further discuss the hardware-software co-design that was essential to fully realize the performance benefits of the FPU when constrained by the memory bandwidth limitations and high penalties for misaligned data access imposed by the memory hierarchy on a BlueGene/L node. We describe several novel compiler and algorithmic techniques to take advantage of this architecture. Using both hand-optimized and compiled code for key linear algebraic kernels, we validate the architectural design choices, evaluate the success of the compiler, and quantify the effectiveness of the novel algorithm design techniques. Preliminary performance data shows that the algorithm-compiler-hardware combination delivers a significant fraction of peak floating-point performance for compute-bound kernels such as matrix multiplication, and delivers a significant fraction of peak memory bandwidth for memory-bound kernels such as daxpy, while being largely insensitive to data alignment.
Structure and Molecular Mechanism of a Nucleobase–Cation–Symport-1 Family Transporter (2008)

The nucleobase-cation-symport-1 (NCS1) transporters are essential components of salvage pathways for nucleobases and related metabolites. Here, we report the 2.85-angstrom resolution structure of the NCS1 benzyl-hydantoin transporter, Mhp1, from Microbacterium liquefaciens. Mhp1 contains 12 transmembrane helices, 10 of which are arranged in two inverted repeats of five helices. The structures of the outward-facing open and substrate-bound occluded conformations were solved, showing how the outward-facing cavity closes upon binding of substrate. Comparisons with the leucine transporter LeuT(Aa) and the galactose transporter vSGLT reveal that the outward- and inward-facing cavities are symmetrically arranged on opposite sides of the membrane. The reciprocal opening and closing of these cavities is synchronized by the inverted repeat helices 3 and 8, providing the structural basis of the alternating access model for membrane transport.

[Electroluminescence from a Mn2+ activated SiO2 : Si film on N(+)-Si substrate]. (2009)

Recently, a monolithic integration of optics and electronics in a single Si chip has attracted a great deal of attention due to its attractive application prospects: the potential for forming high speeded information processing and transmission, and inexpensive and low power silicon chip. Developing high-efficiency silicon-based light sources is the main task in silicon photonics. In the present paper the authors explore a potential way for silicon-based light-emitting application. A Mn(2+)-activated silicon-rich silicon oxide (SiO2 : Si : Mn2+) film was prepared on the n(+)-type silicon substrate using co-sputtering technique followed by doping and activation of Mn with a thermal diffusion method. High-resolution transmission electronic microscope study shows that the film is embedded with 3-5 nm silicon nanocrystals. Bright green photoluminescence (PL) from the film was observed under ultraviolet radiation and peaked at 524 nm (2.36 eV), the decay time of which is 0.8 ms. It is generally believed that the green radiation originates from 4T1 --> 6A1 transition in Mn2+. The PL excitation spectrum of the film, monitored at 524 nm, has a peak of 254 nm, similar to that of the Zn2 SiO4 : Mn film. It is believed that the strong 254 nm absorption is attributed to Mn2+ --> Mn3+ ionization or ds --> d4s transition. A very broad electroluminescence spectrum ranging from 400 to 800 nm, covering almost the whole visible band, was observed from the device made of the SiO2 : Si : Mn2+ film at low reverse biases. The threshold voltage of the device is as low as 5 V. Spectra of the device demonstrate that the electroluminescence is attributed to Mn2+ and luminescence centers in the Si-rich SiO2 film. The authors interpret that Mn2+ excitation is mainly due to direct impact excitation of hot electrons, silicon nanocrystals in the SiO2 film help electrons tunnel from a silicon nanocrystal to an adjacent one, and are advantageous for generating hot electrons to excite Mn2+.
A Comparison of Basic CPU (1990)

In this paper, we present the results of a simulation study comparing three basic algorithms that schedule independent tasks in multiprocessor versions of UNIX. Two of these algorithms, namely Central Queue and Initial Placement, are obvious extensions to the standard uniprocessor scheduling algorithm and are in use in a number of multipro- cessor systems. A third algorithm, Take, is a varia- tion on Initial Placement, where processors are allowed to raid the task queues of the other proces- sors. Our simulation results show the difference between the performance of the three algorithms to be small when scheduling a typical UNIX workload running on a small, bus-based, shared memory mul- tiprocessor. They also show that the Take algo- rithm performs best for those multiprocessors on which tasks incur overhead each time they migrate. In particular, the Take algorithm appears to be more stable than the other two algorithms under extreme conditions.
Tunable sampled-grating DBR lasers using quantum-well intermixing (2002)

Widely tunable lasers are key components for wavelength division multiplexing fiber optic networks. They reduce cost in sparing, enable dynamic networking applications, and present opportunities for future monolithically integrated wavelength division multiplexing components. The sampled-grating distributed Bragg reflector (SGDBR) laser is ideal for these purposes. The authors present a centered quantum-well SGDBR laser which uses quantum-well intermixing in order to improve device characteristics over previous designs. The mode overlap is improved by 50% over the offset quantum-well design, improving the modal gain. Current injection tuning in the intermixed material is demonstrated for the first time; the maximum modal group index change was measured to be 1%.
Different Types of Luteal Sub-Function in Relation to Pregnancy RateIn Nelore Cattl (2015)

This study was carried out to determine different types of luteal sub-function in relation to pregnancy rate in Nelore cattle. Fifty seven cows were used. Blood samples were collected twice per week for determining progesterone concentration within estrous cycle. Seven progesterone profiles were found normal progesterone profiles, delayed progesterone profiles, insufficient progesterone profiles, short luteal phase, long luteal phase, basal progesterone profile, and non-response to prostaglandin F2 treatment. Normal progesterone profiles (52.8 %) were higher than abnormal progesterone profiles. Therefore, pregnancy rate was significant higher in normal progesterone profile (45.6 %) compare to other abnormal progesterone profiles. In conclusion, Different progesterone profiles were observed in individual animal after AI. In addition to, it was observed that the post insemination progesterone profile has an effect on the pregnancy rates in Nelore cattle. Keywords: progesterone profiles, pregnancy rate, artificial insemination, Nelore cattle
