A new maximum power point tracking controller for photovoltaic power generation (2003)

This paper proposes a new maximum power point tracking (MPPT) method in combination with one-cycle control for photovoltaic power generation. This control scheme is based on the automatic current-adjusting feature of one-cycle control. The output current of the inverter can be adjusted according to the voltage of the photovoltaic (PV) array so as to extract the maximum power from it. In the mean time, one-cycle control guarantees that the output current is in the same shape of and in phase with the grid voltage. All these are accomplished in one power stage and a simple control circuit. No detection and calculation of power are needed. Compared with previously proposed approaches, this method is much more efficient and more cost-effective and yet exhibits excellent performance. The principle is explained qualitatively and extensive experiments have been carried out to verify and validate the proposed method.
Identification of a T cell receptor beta chain variable region, V beta 20, that is differentially expressed in various strains of mice. (1991)

A cDNA library of TCR beta chain transcripts from BALB/c thymocytes was constructed using anchored polymerase chain reaction (PCR). Screening of this library led to the identification of a V beta gene segment, V beta 20, structurally related to V beta 3 and V beta 17. Genomic analysis of mice displaying deletions in their V beta loci, together with mapping of cosmid clones, situated V beta 20 2.5 kb beside V beta 17. The expression of V beta 20 was estimated by PCR in mice of different H-2 and Mls types. Peripheral T cells from H-2k and H-2d mice did not express V beta 20, whereas in I-E-negative mice (C57Bl/6 and SJL), V beta 20 transcripts were detected. The lack of V beta 20 transcripts in (C57Bl/6 x CBA/J)F1, (C57Bl/6 x BALB/c)F1, and in congenic B6.H-2k mice suggests that the differential use of V beta 20 is due to an I-E-mediated clonal deletion process. The involvement of the Mls super antigens was excluded by analysis of all Mls type combinations. The nature of the V beta 20-deleting element(s) is discussed in the context of the I-E/superantigen systems controlling the expression of V beta 11 and V beta 17.
Efficient QoS for multi-tiered storage systems (2012)

Multi-tiered storage systems using tiers of SSD and traditional hard disk is one of the fastest growing trends in the storage industry. Although using multiple tiers provides a flexible trade-off in terms of IOPS performance and storage capacity, we believe that providing performance isolation and QoS guarantees among various clients, gets significantly more challenging in such environments. Existing solutions focus mainly on either disk-based or SSD-based storage backends. In particular, the notion of IO cost that is used by existing solutions gets very hard to estimate or use. In this paper, we first argue that providing QoS in multi-tiered systems is quite challenging and existing solutions aren’t good enough for such cases. To handle their drawbacks, we use a model of storage QoS called as reward scheduling and a corresponding algorithm, which favors the clients whose IOs are less costly on the backend storage array for reasons such as better locality, readmostly sequentiality, smaller working set as compared to SSD allocation etc. This allows for higher efficiency of the underlying system while providing desirable performance isolation. These results are validated using a simulation-based modeling of a multi-tiered storage system. We make a case that QoS in multi-tiered storage is an open problem and hope to encourage future research in this area. 1
Thrust Mixing, Saturation, and Body-Rate Control for Accurate Aggressive Quadrotor Flight (2016)

Quadrotors are well suited for executing fast maneuvers with high accelerations but they are still unable to follow a fast trajectory with centimeter accuracy without iteratively learning it beforehand. In this paper, we present a novel body-rate controller and an iterative thrust-mixing scheme, which improve the trajectory-tracking performance without requiring learning and reduce the yaw control error of a quadrotor, respectively. Furthermore, to the best of our knowledge, we present the first algorithm to cope with motor saturations smartly by prioritizing control inputs which are relevant for stabilization and trajectory tracking. The presented body-rate controller uses LQR-control methods to consider both the body rate and the single motor dynamics, which reduces the overall trajectory-tracking error while still rejecting external disturbances well. Our iterative thrust-mixing scheme computes the four rotor thrusts given the inputs from a position-control pipeline. Through the iterative computation, we are able to consider a varying ratio of thrust and drag torque of a single propeller over its input range, which allows applying the desired yaw torque more precisely and hence reduces the yaw-control error. Our prioritizing motor-saturation scheme improves stability and robustness of a quadrotor's flight and may prevent unstable behavior in case of motor saturations. We demonstrate the improved trajectory tracking, yaw-control, and robustness in case of motor saturations in real-world experiments with a quadrotor.

Performance of Targeted Library Preparation Solutions for SARS-CoV-2 Whole Genome Analysis (2020)

Single next-generation sequencing (NGS) proved to be an important tool for monitoring the SARS-CoV-2 outbreak at the global level Until today, thousands of SARS-CoV-2 genome sequences have been published at GISAID (Global Initiative on Sharing All Influenza Data) but only a portion are suitable for reliable variant analysis. Here we report on the comparison of three commercially available NGS library preparation kits. We discuss advantages and limitations from the perspective of required input sample quality and data quality for advanced SARS-CoV-2 genome analysis.
Religion and China’s Public Diplomacy in the Era of Globalization (2015)

:Since the end of the cold war, especially since the 9/11, religion’s importance has risen sharply in international relations. It has already become an inevitable and important factor in the strategic considerations of national security and foreign policy in various countries. Therefore, in their considerations for foreign and strategic relations, public diplomacy associated with national religious image, or the so-called religious public diplomacy (faith diplomacy), which depends on their own religions and religious groups as the chief carrier, connecting foreign religious organizations and believers as the main object, and largely concerning about religion and relevant issues, is also gradually rising. This article argues that currently religious groups, academia and the government together constitute the main framework of China’s religious public diplomacy, and gradually form a pattern of divisions in which religious groups can implement programs, academia offer recommendations and suggestions, and governments coordinate; and, that the three sectors share resources, work together and have positive interaction to significantly promote religious public diplomacy of the country.
The Vitreous Body (1990)

This is a transparent jelly occupying, in man and most vertebrates, by far the largest part of the globe. As Fig. 1.1 shows, it is bounded by the retina, ciliary body and the posterior capsule of the lens. If the sclera is cut through round the equator, the posterior half with the attached retina comes away from the vitreous body, leaving this suspended from its firm attachments to the ciliary body and pars plana of the retina. To isolate it completely from these attachments careful cutting and scraping are necessary.
Mechanisms of acid injury in porcine gastroesophageal mucosa (1996)

Undissociated SCFA rapidly penetrate the outer barrier and acidify underlying viable tissue. Cellular acidification inhibits Na pumping and osmoregulation, resulting in cell swelling and necrosis. In contrast, HCl induces and increase in outer barrier permeability before accessing the transporting cells, a much longer process ( > or = 5 hours) requiring a lower pH. These studies suggest that microbial production of SCFA may be important in the pathogenesis of porcine gastric ulcers.

A Meta-Analysis of Somatic KCNJ5 K<sup>+</sup>Channel Mutations In 1636 Patients With an Aldosterone-Producing Adenoma (2015)

Meta-analysis showed that more pronounced hyperaldosteronism, young age, female gender, and larger tumors are the phenotypic features of APA patients with KCNJ5 mutations. No significant differences in blood pressure and serum K(+) was found, which suggests that these clinical features do not help in identifying mutated APA patients.
Proinflammatory cytokine-induced cellular senescence of biliary epithelial cells is mediated via oxidative stress and activation of ATM pathway: A culture study (2008)

Cellular senescence is reportedly involved in cholangiopathy in primary biliary cirrhosis and oxidative stress is proposed as a pathogenetic factor in biliary epithelial cells (BECs). This study investigated the involvement of proinflammatory cytokines (IFN-beta, IFN-gamma and TNF-alpha) and ataxia telangiectasia-mutated (ATM)/p53/ p21(WAF1/Cip1) pathway with respect to oxidative stress in cellular senescence of BECs. H(2)O(2) treatment (oxidative stress) induced phosphorylation (activation) of ATM and p53 and also p21(WAF1/Cip1) expression in BECs. Treatment with inflammatory cytokines generated reactive oxygen species (ROS) in cultured BECs followed by activation of the ATM/p53/p21(WAF1/Cip1) pathway and the induction of cellular senescence. Pre-treatment with ATM inhibitor (2-aminopurine) and antioxidant (N-acetylcysteine) significantly blocked the cellular senescence of BECs induced by oxidative stress or inflammatory cytokines. In conclusion, proinflammatory cytokines induce ROS generation and activate the ATM/p53/p21(WAF1/Cip1) pathway, followed by biliary epithelial senescence. This senescent process may be involved in the development of destructive cholangiopathy in humans.

Enzymatic Treatments of Pulps (1992)

The pulp and paper industry processes huge quantities of lignocellulosic biomass every year; the technology for pulp manufacture is highly diverse, and numerous opportunities exist for applying microbial enzymes. Enzymes have been used to increase pulp fibrillation and water retention and to reduce beating times in virgin pulps. With recycled fibers, enzymes have been used to restore bonding and increase freeness. Specialized applications include the reduction of vessel picking in tropical hardwood pulps and the selective removal of xylan from dissolving pulps. The single most important application is in the removal of lignin from kraft pulps. Both lignin-degrading and hemicellulose-degrading enzymes have been shown to be effective for this purpose, but many other microbial enzymes remain to be examined. Eventually, microbial enzymes in conjunction with the appropriate chemical of thermochemical extractions might enable the fractionation of cellulose, hemicellulose, and lignin from pulps and other lignocellulosics.
Review: The use of shock waves in medicine—a tool of the modern OR: An overview of basic physical principles, history and research (2000)

Extracorporeal-generated shock waves were first used in medical therapy, to disintegrate kidney stones, approximately 20 years ago. Since this time, shock waves have changed the treatment of urolithiasis substantially and are now the first-choice treatment for kidney and ureteral stones. First clinical investigations of the shock-wave treatment of Induratio Penis Plastica (IPP) are showing promising results. Shock waves have also been used in orthopaedics and traumatology, to treat insertion tendinitis, non-unions or delayed unions, avascular necrosis of the head of femur and other necrotic bone alterations. Shock-wave application has also been used in the treatment of horse tendons, ligaments and bones in veterinary medicine. The theory of shock-wave therapy for orthopaedic diseases involves the stimulation of healing processes in tendons, surrounding tissue and bones. This is a completely different approach from that of urology, where shock waves are used for disintegration. This paper gives an overview of the basic physical principles of shock waves, and the history and basic research behind shock-wave use in medicine.
Comment on “Local impermeant anions establish the neuronal chloride concentration” (2014)

Glykys et al. (Reports, 7 February 2014, p. 670) conclude that, rather than ion transporters, "local impermeant anions establish the neuronal chloride concentration" and thereby determine "the magnitude and direction of GABAAR currents at individual synapses." If this were possible, perpetual ion-motion machines could be constructed. The authors' conclusions conflict with basic thermodynamic principles.
A growing challenge: addressing "unmet need". (1994)

Even though family planning programs in recent decades have helped increase the level of contraceptive use among married women in less developed countries to an overall rate of 50%, an enormous number of people are still denied the good quality contraceptive services which they want and need. Approximately 20% of fecund women in union who want to avoid becoming pregnant, 120 million women, are not using contraception. Unmet need for contraception is also high among sexually active and single teenagers, people who already use one method but are dissatisfied with that method, people who have access to only one or two methods, and men. Demographic data suggest that half of women in low prevalence countries lack knowledge about contraceptives or have religious reservations about using them, while in countries of high contraceptive prevalence, health concerns are the major reason for nonuse, followed by infrequent sex, and lack of knowledge. Family planning programs are seeking new ways to address the unmet need for contraceptive services variously among married women, men, adolescents, refugees, and those who turn to abortion because of poor access to contraceptives. Quality care is called for when providing such services. Postpartum women, serving rural areas, involving men, and tomorrow's parents are discussed.
Pulmonary Vasoconstriction Due to Nonocclusive Distention of Large Pulmonary Arteries in the Dog (1968)

The pulmonary vascular changes caused by distention of the pulmonary artery with the lumen fixed were compared to those produced by occlusive arterial distention. In 13 urethane-anesthetized dogs, nonocclusive distention was produced by distention of a corrugated rubber cuff around a hollow metal cylinder affixed to the end of a cardiac catheter. In 10 other dogs, occlusive distention was produced by inflation of a standard balloon catheter. Pressures were measured in large and small pulmonary veins and in the left and right atria with transseptal techniques, and in the pulmonary and femoral arteries. Simultaneously, pulmonary blood volume and flow were measured with dyedilution techniques. Pulmonary arteriovenous shunting was studied with the hydrogen-electrode technique. Nonocclusive distention of a pulmonary artery greatly increased pulmonary arterial and venous pressure and decreased pulmonary blood volume without changing left atrial pressure or cardiac output. Pulmonary vascular resistances increased, and pulmonary arteriovenous shunting was detected. Occlusive distention of one pulmonary artery caused smaller increases in pressure in the pulmonary artery and vein of the unobstructed lung. Vascular resistances in the unobstructed lung decreased, while blood volume and flow in that lung doubled. Pulmonary arterial distention leads to active constriction of the pulmonary arteries and veins, but these responses may be obscured by the passive responses to increasing blood flow and volume.

Evidence for both local and central regulation of rat rod outer segment disc shedding. (1980)

Rats entrained to a 7 A.M.:7 P.M. lighting cycle had one eye patched and then were placed in either constant light or in a 2 A.M.:2 P.M. lighting cycle. In both cases, the patched eyes maintained the original pattern of rod outer segment (ROS) disc shedding, whereas the open eyes responded to the ambient lighting conditions. When the optic nerves were severed at the optic chiasm, the shedding rhythm persisted, but it was no longer possible to shift the rhythm to a new lighting cycle. From these experiments we conclude that ROS disc shedding is regulated both by local oscillators within the orbit as well as by central elements.
An infrared pneumatic detector made by micromachining technology (1995)

We present a micromachined infrared IR detector based on the principle of the Golay cell. The detector basically consists of a sealed cavity, in which the heat generated by absorbed in light results in an increased gas pressure. This pressure rise is detected capacitively. The theoretical responsivity and noise equivalent of a micromachined device are calculated, and it is shown that a detectivity of 3.6*109 cm Hz1/2 W-1 can be expected for a 1 mm2 micromachined version. Further, we propose the use of a micromachined pneumatic gas leak in order to avoid thermal drift. A prototype was fabricated using Si and Pyrex micromachining techniques, and confirmed the principle of operation. The preliminary experimental results are compared to theory.
Physical Characterization of Two-Terminal SOT-MRAM Cell (2018)

Due to its non-volatility, fast operation, and high endurance, magnetoresistive random access memory (MRAM) based on current-induced switching originating from spin-transfer torque (STT) is one of the most credible candidates to succeed present random access memory technologies. However, the STT-MRAM technology has many limitations, including high critical switching current and stochastic nature of STT-switching, which are unsuitable for ultrafast operation of memory device at nanosecond (ns) and sub-ns regimes. A relatively new switching concept, based on the spin-orbit torque (SOT) effect, is an excitation of torque induced by an in-plane current, typically in a heavy-metal layer, showing potential to overcome these limitations. On the flip side, all the SOT-MRAM cells studied so far require a three-terminal structure to apply the in-plane current, which increases the cell size because of two additional isolated contacts and associated interconnects. In this paper, we designed, fabricated, and analyzed the world first two-terminal SOT-MRAM cell, in which an in-plane current and out-of-plane current are simultaneously generated upon the application of a voltage. We have further confirmed that the switching mechanism is SOT-dominant, and moreover, compared to STT technology, the critical write current is reduced by more than 70% under the same MRAM architecture with 110 nm-diameter magnetic tunnel junctions (MTJs).
