Throughput Maximization for Backscatter- and Cache-Assisted Wireless Powered UAV Technology (2022)

This paper investigates a wireless powered unmanned aerial vehicle (UAV) communication network with backscatter and caching technologies. Specifically, we assume a self-energized UAV with a cache memory is deployed as a flying backscatter device (BD), term the UAV-enabled BD (UB), to relay the source’s signals to the destination. Whereas the source S can act as a wireless charging station or a base station to supply power or transmit information to the UB using the dynamic time splitting (DTS) method. The UAV utilizes its harvested energy for backscattering (i.e., passive communication) and transmit information (i.e., active communication) to the destination. In this context, we aim to maximize the total throughput by jointly optimizing the DTS ratio and the UB’s trajectory with caching capability at the UB. The formulation is troublesome to solve since it is a non-convex problem. To find solutions, we decompose the original problem into two sub-problems, whereas we first optimize the DTS ratio for a given UB’s trajectory and the UB’s trajectory optimization for a given DTS ratio. By using the KKT conditions, a closed-form expression for the optimal value of the DTS ratio is obtained, greatly reducing the computation time. Moreover, the solution of the second sub-problem can be acquired by adopting the successive convex approximation (SCA) technique. Consequently, an efficient alternating algorithm is proposed by leveraging the block coordinate descent (BCD) method. To show the advantages of the proposed BCD-based algorithm, we also provide the solution of the original problem applying the inner approximation (IA) method. Finally, the intensive numerical results demonstrate that our proposed schemes achieve significant throughput gain in comparison to the benchmark schemes.

African swine fever: Update on Eastern, Central and Southern Africa (2019)

Control of African swine fever (ASF) in countries in Eastern, Central and Southern Africa (ECSA) is particularly complex owing to the presence of all three known epidemiological cycles of maintenance of the virus, namely an ancient sylvatic cycle involving the natural hosts and vectors of the disease as well as domestic cycles with and without involvement of natural vectors. While the situation is well documented in some of the countries, for others very little information is available. In spite of the unfavourable ASF situation, the pig population in the sub-region has grown exponentially in recent decades and is likely to continue to grow in response to rapid urban growth resulting in increasing demand for animal protein by populations that are no longer engaged in livestock production. Better management of ASF will be essential to permit the pig sector to reach its full potential as a supplier of high quality protein and a source of income to improve livelihoods and create wealth. No vaccine is currently available and it is likely that, in the near future, the sub-region will continue to rely on the implementation of preventive measures, based on the epidemiology of the disease, to avoid both the devastating losses that outbreaks can cause and the risk the sub-region poses to other parts of Africa and the world. The current situation in the ECSA sub-region is reviewed and gaps in knowledge are identified in order to support ongoing strategy development for managing ASF in endemic areas.
Symbolic representation with ordered function templates (2003)

Binary Decision Diagrams (BDDs) often fail to exploit sharing between Boolean functions that differ only in their support variables. In a memory circuit, for example, the functions for the different bits of a word differ only in the data bit while the address decoding part of the function is identical. We present a symbolic representation approach using ordered function templates to exploit such regularity.Templates specify functionality without being bound to a specific set of variables. Functions are obtained by instantiating templates with a list of variables. We ensure canonicity of the representation by requiring that templates are normalized and argument lists are ordered. We also present algorithms for performing Boolean operations using this representation. Experiments with a prototype implementation built on top of CUDD indicate that function templates can dramatically reduce memory requirements for symbolic simulation of regular circuits.
Synthetic studies of (+)-discodermolide: Gram -scale synthesis, solution conformation, and analog design, synthesis, and evaluation (2002)

The dissertation contained herein describes synthetic studies of (+)-discodermolide (1), a deep-sea marine sponge metabolite possessing potent anticancer activity. First, a triply convergent total synthesis of (+)-discodermolide (1) has been achieved, exploiting a common precursor ( CP) to permit the rapid and efficient construction of three advanced subtargets (A, B, C). Importantly, this first preparative-scale synthesis of (+)-discodermolide is highly efficient, proceeding in 6% overall yield (longest linear sequence, 24 steps; 33 steps overall), stereocontrolled, and has produced 1.043 g of crystalline 1, available for further evaluation of the biological profile.* Secondly, studies were performed to elucidate the conformation of (+)-discodermolide in solution. A combination of 1 and 2-D NMR techniques and computational studies revealed that in McCN (+)-discodermolide exists in a helical conformation remarkably similar to the solid-state. Conformational analysis of the solution and solid-state conformational properties of (+)-discodermolide suggests that A1,3 and syn-pentane nonbonded interactions, in addition to intramolecular hydrogen bonding, play a major role in defining the overall conformation.* Having achieved a highly efficient, gram-scale synthesis in addition to defining the solution conformation of the natural product, we turned our attention to the design and synthesis of four distinct series of analogs. In our first-generation analogs, structural simplifications to the C(1–7) and C(14) regions were implemented and resulted in better or no significant loss of cytotoxicity. The second series of analogs consisted of fragment C congeners in which five stereocenters were removed from the C(1–7) region via the utilization of aromatic scaffolds as δ-lactone mimics. These congeners also displayed potent cell growth inhibitory activity. In the third series of analogs, photoaffinity and fluorescent congeners were designed and synthesized that hold the promise of labeling the respective tubulin and cellular sites of (+)-discodermolide binding. The final series of analogs included structural simplifications in the fragment A C(14–24) region, in addition to a C(19) carbamate functional group scan. Taken together, the analogs described herein further develop structure-activity relationships, contribute to the definition of the minimum structure element required for cytotoxicity, and hold the promise of characterizing the (+)-discodermolide-tubulin binding pocket.* *Please refer to dissertation for diagrams.

Enhancement of pump efficiency of a visible wavelength organic distributed feedback laser by resonant optical pumping (2011)

A 22× reduction in laser pump threshold and a 23× enhancement in energy conversion have been demonstrated on a second order distributed feedback (DFB) laser using a resonant optical pumping (ROP) technique. The ROP scheme couples the excitation light into a distinct resonant mode of the laser cavity through the illuminating at a specific resonant incident angle. Coupling excitation light into the resonant mode results in an enhanced near-field, which significantly increases pump absorption by the active medium. Consequently, high power conversion efficiency between pumping light and lasing emission is achieved and laser pump threshold power is reduced.
A Review of Anti-Inflammatory Drugs Use in the Treatment of People Infected by Coronavirus Disease 2019 (COVID-19) (2020)

The pandemic flare-up of coronavirus disease 2019 (COVID-19) is quickly spreading everywhere throughout the world. Reports from China indicated that about 20% of patients created severe disease, bringing about a casualty of 4%. In the previous two months, we clinical immunologists took an interest in multi-rounds of MDT (multidiscipline group) conversation on the counter aggravation the executives of basic COVID-19 patients, with our partners dispatched from Chinese driving PUMC Hospital to Wuhan to concede and treat the most serious patients. Here, from the point of view of clinical immunologists, we will examine the clinical and immunological attributes of severe patients, and sum up the current proof and offer our involvement with hostile to anti-inflammation treatment, including glucocorticoids, IL-6 adversary, JAK inhibitors and chloroquine/hydroxychloroquine, of patients with extreme COVID-19 that may have an impeded safe framework.
Metabolic engineering of Escherichia coli to produce succinate from soybean hydrolysate under anaerobic conditions (2018)

It is of great economic interest to produce succinate from low-grade carbon sources, which can enhance the competitiveness of the biological route. In this study, succinate producer Escherichia coli CT550/pHL413KF1 was further engineered to efficiently use the mixed sugars from non-food based soybean hydrolysate to produce succinate under anaerobic conditions. Since many common E. coli strains fail to use galactose anaerobically even if they can use it aerobically, the glucose, and galactose related sugar transporters were deactivated individually and evaluated. The PTS system was found to be important for utilization of mixed sugars, and galactose uptake was activated by deactivating ptsG. In the ptsG<sup>-</sup> strain, glucose, and galactose were used simultaneously. Glucose was assimilated mainly through the mannose PTS system while galactose was transferred mainly through GalP in a ptsG<sup>-</sup> strain. A new succinate producing strain, FZ591C which can efficiently produce succinate from the mixed sugars present in soybean hydrolysate was constructed by integration of the high succinate yield producing module and the galactose utilization module into the chromosome of the CT550 ptsG<sup>-</sup> strain. The succinate yield reached 1.64 mol/mol hexose consumed (95% of maximum theoretical yield) when a mixed sugars feedstock was used as a carbon source. Based on the three monitored sugars, a nominal succinate yield of 1.95 mol/mol was observed as the strain can apparently also use some other minor sugars in the hydrolysate. In this study, we demonstrate that FZ591C can use soybean hydrolysate as an inexpensive carbon source for high yield succinate production under anaerobic conditions, giving it the potential for industrial application.
Position and Posture Control Using Pneumatic Actuator Drive Robot Hand (2016)

Many researches about robot hands are developed recently. Motor drive robot hand is mainly used as the driving source of the artificial hand because it can perform highly precise position and force control. However, when the motor drive robot hand hits human, it may cause injuries. Furthermore, the robot hand uses many sensors so the robot hand becomes expensive. In this study, pneumatic muscle actuators are used as the driving source of the robot hand to assure safety. Object level impedance control, control law which only needs link angle sensors, is used to make the control system in low price. Experiments were done with two control object, two link pneumatic muscle manipulator and pneumatic muscle robot hand, to verify the effectiveness of the control system.
Frequent HOXA11 and THBS2 promoter methylation, and a methylator phenotype in endometrial adenocarcinoma. (2003)

Endometrial adenocarcinomas have a methylator phenotype. No correlation between MeI and clinicopathologic variables in early stage tumors was observed. High rates of methylation were found in the HOXA11 and THBS2 promoter regions. HOXA11 promoter methylation was significantly more frequent in recurrent than nonrecurrent cases. HOXA11 methylation in early stage endometrial cancer is associated with poor outcome.
Coordination of central and autonomic nervous systems during sleep (1996)

O2 reacts with propanediols via homogeneous pathways at 400-500 K. 1,2-Propanediol forms CH3CHO, HCHO, and CO2 via oxidative C--C cleavage and acetone via dehydration routes, while symmetrical 1,3-propanediol undergoes dehydration and oxidative dehydrogenation to form, almost exclusively, acrolein (ca. 90 % selectivity). The products formed and their kinetic dependence on reactant concentrations are consistent with radical-mediated pathways initiated by O2 insertion into C--H bonds in a β position relative to oxygen atoms in diol reactants. Propagation involves β-scission reactions that form hydroxyl and hydroxyalkyl radicals. Acrolein/O2/H2O mixtures from the homogeneous oxidation of 1,3-propanediol form acrylic acid (with 90 % yield) in tandem reactors containing molybdenum-vanadium oxide catalysts. These data reveal the unique reactivity of diols, compared with triols and alkanols, in homogeneous oxidations, while also providing useful insight into the molecular basis for reactivity in biomass-derived oxygenates.
Prostaglandin E2receptor subtype EP2- and EP4-regulated gene expression profiling in human ciliary smooth muscle cells (2010)

Prostanoids are an important class of intraocular pressure (IOP)-lowering antiglaucoma agents that act primarily via increased uveo-scleral aqueous humor outflow through the ciliary body. We have developed two novel PGE(2) analogs that are specific agonists for the PGE(2) receptor subtypes EP2 and EP4, respectively. To identify gene regulatory networks and key players that mediate the physiological effects observed in vivo, we performed genomewide expression studies using human ciliary smooth muscle cells. Quantitative real-time RT-PCR confirmed a largely overlapping gene expression profile subsequent to EP2 and EP4 agonist treatment, with 65 significantly regulated genes identified overall, 5 being specific for the EP2 agonist and 6 specific for the EP4 agonist. We found predicted functional cAMP-response elements in promoter regions of a large fraction of the predominantly upregulated genes, which suggests that the cAMP signaling pathway is the most important intracellular signaling pathway for these agonists in these cells. Several target genes were identified that, as part of complex regulatory networks, are implicated in tissue remodeling processes and osmoregulation (e.g., AREG, LOXL3, BMP2, AQP3) and thus may help elucidate the mechanism of action of these IOP-lowering drugs involving the uveo-scleral outflow path.
DETERMINATION OF PREOPERATIVE RISK FACTORS FOR ILIOPSOAS TENDONITIS (2023)

Iliopsoas impingement occurs in between 5-30% of patients after hip arthroplasty and has been thought to only be caused by an oversized cup, cup malpositioning, or the depth of the psoas valley. However, no study has associated the relationship between preoperative measurements with the risk of impingement. This study sought to assess impingement between the iliopsoas and acetabular cup using a novel validated model to determine the risk factors for iliopsoas impingement. 413 patients received lower limb CT scans and lateral x-rays that were segmented, landmarked, and measured using a validated preoperative planning protocol. Implants were positioned according to the preference of ten experienced surgeons. The segmented bones were transformed to the standing reference frame and simulated with a novel computational model that detects impingement between the iliopsoas and acetabular cup. Definitions of patients at-risk and not at-risk of impingement were defined from a previous validation study of the simulation. At-risk patients were propensity score matched to not at-risk patients. 21% of patients were assessed as being at-risk of iliopsoas impingement. Significant differences between at-risk patients and not at-risk patients were observed in standing pelvic tilt (p &lt;&lt; 0.01), standing femoral internal rotation (p &lt;&lt; 0.01), medio-lateral centre-of-rotation (COR) change (p &lt;&lt; 0.01), supine cup anteversion (p &lt;&lt; 0.01), pre- to postoperative cup offset change (p &lt;&lt; 0.001), postoperative gross offset (p = 0.009), and supero-inferior COR change (p = 0.02). Impingement between the iliopsoas and acetabular cup is under-studied and may be more common than is published in the literature. Previously it has been thought to only be related to cup size or positioning. However, we have observed significant differences between at-risk and not at-risk patients in additional measurements. This indicates that its occurrence is more complex than simply being related to cup position.

Characteristics of hybrid modes in biaxial planar waveguides (1990)

Light propagation in biaxially anisotropic dielectric crystals may be conveniently described by the two-sheeted wave vector surface. Each sheet represents the properties of one of the two allowed orthogonally polarized propagating waves. In general, the two allowed propagating waves are "extraordinary-like," and the Poynting (ray) vector direction for each wave differs from the wave vector direction. Dielectric planar waveguides may be biaxial, either naturally or through the electro-optic effect (as is frequently the case with modulators). The electromagnetic fields in a biaxial waveguide consist of a weighted sum of four "extraordinary-like" plane waves which are coupled. The directional properties of the hybrid guided modes are determined by using a complete and concise coordinate-free approach for isolating each sheet of the wave vector surface. The ranges of propagation constants for the hybrid modes are determined as a function of the orientation of the principal dielectric axes, and this leads to the classification scheme that uniquely identifies each guided mode.
Capacitive Load Induced Field Stresses on Generators Connected into DC Systems (1985)

Sometimes, a synchronouis machine experiences a sudden increase. in capacitive loading, due for example to a load rejection by the blocking of an hvdc rectifier, or to the tripping of the synchronous machines when connected to a predominantly capacitive load. This sudden increase in capacitive loading can initiate oscillations in the stator circuit, which are reflected as sudden oscilldtions in the machine's field current. In machines with solid state exciters without reverse current capability, severe oscillations may momentarily try to reduce the field current to zero, and result in excessive field overvoltages. It is these overvoltages, that this paper attempts to study, through detailed simulations and also through demonstration on a laboratory setup. The situation discussed here relates to such phenomena occuring on machines connected to hvdc rectifier stations, although similar situations could also exist in other systems.
A 4b/Cell 8Gb NROM Data-Storage Memory with Enhanced Write Performance (2008)

The increasing demand for cost reduction of data storage solutions calls for both cell-size shrink, as well as compressing more bits of data into the storage element. Yet the low cost solution is required to have fast enough write operation to fit density-hungry applications. An 8 Gb data flash storage device based on 4b/cell NROM technology is presented in this paper. A major improvement in write time is accomplished through improvement of programming techniques, erase scheme and sensing methods.
Single-Photon Intensity Interferometry (SPIIFy): utilizing available telescopes (2017)

One of the main scientific goals of optical interferometers is to measure the angular diameters of stars. These measurements, combined with precise distance measurements, such as those from the upcoming Gaia satellite, can provide improved constraints on stellar linear diameters and effective temperature. We describe a modular intensity interferometer system using commercially available single-photon detectors. We present our calculations on the sensitivity and uv-plane coverage using these modules mounted on existing telescopes on Kitt Peak, Arizona. Determining accurate stellar properties is important for testing models of stellar evolution as well as for deriving physical properties of transiting exoplanets. Our simulations indicate that we should be able to measure stellar diameters of bright stars with AB magnitude ≤6 with a precision of ≥5 per cent in a single night of observation.
[Invited Papers] Bioenergy Research in Kyoto University 21COE Program on Sustainable Energy System (2004)

It is anticipated that the energy consumption in the 21st century is rapidly increased with an explosive population as well as the leveling-up of our living conditions to the higher level. Since an increase in energy consumption will result in a serious situation for the survival of our mankind, it is urgently necessary for us to improve the present energy systems and protect our beautiful terrestrial environments. To guarantee the energy security, it is required that the sustainable energy system should be established for the future. 
For this goal, we had proposed Establishment of Center of Excellence (COE) on Sustainable Energy System for the 21st century COE program, and our proposal was accepted in 2002 by the Japanese government. The research program in our proposal consists of four main tasks, solar energy, hydrogen energy, bioenergy and evaluation of total energy system to achieve sustainable energy system, aiming at the establishment of environmentally-friendly society. In this paper, current progress in bioenergy research in this program is introduced on sustainable energy system.
