A 24.2%-Efficiency III-V/CuInGaSe Mechanical Stacking Multi-Junction Solar Cells Using Semiconductor Bonding Method (2014)

This paper shows a high efficiency III-V/CuInGaSe (CIGSe) mechanical stacking multi-junction solar cells fabricated with unique direct bonding method. A three-junction cell with GaInP (Eg-1.89 eV)/GaAs(Eg- 1.42eV)/ CIGSe (Eg-1.2 eV) was realized by integrating a conductive Pd nanoparticle alignment with the van der Waals bonding technique. The obtained efficiency was 24.2%, which was the highest value as the III-V/CIGSe cell combination. According to our simulation, the efficiency can be reached over 28 % under the expected open-circuit voltage (2.8V). These results suggested the high potential of our bonding method even with the heterogeneous cell combinations.

Output factor constituents of a high‐energy photon beam (1988)

Measurements designed to separate primary and various scatter components of central axis dose of the highest energy photon beam of the CGR Saturne 25 linear accelerator are described. This beam has an unusually large output variation with field size. The measurements are performed both in air and in a water phantom, with and without an aperture external to the collimator system. Results are presented in the form of relative output factors for different field sizes due to (i) flattening filter scatter, (ii) water phantom scatter, (iii) collimator backscatter into the monitor chamber, and (iv) collimator forward scatter onto the central axis. It is found that the flattening filter is the single largest scatter component, but that each of the other factors is significant in determining the output dose per monitor unit as a function of field size.
Photo‐Switchable Behavior of Azobenzene‐Dye‐Modified Silica Nanoparticles and Their Assembly With Cyclodextrin Derivatives (2012)

Abstract The photochemically directed self‐assembly of azobenzene‐ and CD‐modified silica particles is presented. Azobenzene‐functionalized SiO 2 nanoparticles are synthesized from carbodiimide‐mediated condensation of the amine‐modified nanoparticles with (phenylazo)benzoic acid. The complementary host particles are synthesized by reacting amino‐SiO 2 with monotosyl‐CD. DLS shows the UV‐triggered agglomeration and disaggregation of the particles due to ( E )‐to‐( Z ) isomerization of the azo group. The photoisomerization process is monitored using UV‐Vis spectrometry. This technique of directed self‐assembly of anisotropic particles is an attractive option to form useful 3D superstructures by tunable agglomeration.
Multi-lingual coreference resolution with syntactic features (2005)

In this paper, we study the impact of a group of features extracted automatically from machine-generated parse trees on coreference resolution. One focus is on designing syntactic features using the binding theory as the guideline to improve pronoun resolution, although linguistic phenomenon such as apposition is also modeled. These features are applied to the Arabic, Chinese and English coreference resolution systems and their effectiveness is evaluated on data from the Automatic Content Extraction (ACE) task. The syntactic features improve the Arabic and English systems significantly, but play a limited role in the Chinese one. Detailed analyses are done to understand the syntactic features ’ impact on the three coreference systems. 1
Functionally Divergent Alleles and Duplicated Loci Encoding an Acyltransferase Contribute to Acylsugar Metabolite Diversity in Solanum Trichomes (2015)

Glandular trichomes from tomato (Solanum lycopersicum) and other species in the Solanaceae produce and secrete a mixture of O-acylsugars (aliphatic esters of sucrose and glucose) that contribute to insect defense. Despite their phylogenetic distribution and diversity, relatively little is known about how these specialized metabolites are synthesized. Mass spectrometric profiling of acylsugars in the S. lycopersicum x Solanum pennellii introgression lines identified a chromosome 11 locus containing a cluster of BAHD acyltransferases with one gene (named Sl-ASAT3) expressed in tip cells of type I trichomes where acylsugars are made. Sl-ASAT3 was shown to encode an acyl-CoA-dependent acyltransferase that catalyzes the transfer of short (four to five carbons) branched acyl chains to the furanose ring of di-acylsucrose acceptors to produce tri-acylsucroses, which can be further acetylated by Sl-ASAT4 (previously Sl-AT2). Among the wild tomatoes, diversity in furanose ring acyl chains on acylsucroses was most striking in Solanum habrochaites. S. habrochaites accessions from Ecuador and northern Peru produced acylsucroses with short (≤C5) or no acyl chains on the furanose ring. Accessions from central and southern Peru had the ability to add short or long (up to C12) acyl chains to the furanose ring. Multiple ASAT3-like sequences were found in most accessions, and their in vitro activities correlated with observed geographical diversity in acylsugar profiles.

Septin filaments exhibit a dynamic, paired organization that is conserved from yeast to mammals (2011)

The septins are conserved, GTP-binding proteins important for cytokinesis, membrane compartmentalization, and exocytosis. However, it is unknown how septins are arranged within higher-order structures in cells. To determine the organization of septins in live cells, we developed a polarized fluorescence microscopy system to monitor the orientation of GFP dipole moments with high spatial and temporal resolution. When GFP was fused to septins, the arrangement of GFP dipoles reflected the underlying septin organization. We demonstrated in a filamentous fungus, a budding yeast, and a mammalian epithelial cell line that septin proteins were organized in an identical highly ordered fashion. Fluorescence anisotropy measurements indicated that septin filaments organized into pairs within live cells, just as has been observed in vitro. Additional support for the formation of pairs came from the observation of paired filaments at the cortex of cells using electron microscopy. Furthermore, we found that highly ordered septin structures exchanged subunits and rapidly rearranged. We conclude that septins assemble into dynamic, paired filaments in vivo and that this organization is conserved from yeast to mammals.
Deployable Inverted-Hat Monopole With 3:1 Constant Gain Bandwidth (2020)

A novel deployable inverted-hat monopole (IHM) antenna is presented for satellite applications. This frequency scalable antenna was designed and verified in very high-frequency (VHF) band (40-160 MHz) for 9U CubeSats and ultrahigh-frequency (UHF) band (200-600 MHz) for 1U CubeSats. The VHF band ultrawideband (UWB) monopole antenna operates from 40 to 160 MHz on an infinite ground plane, with emphasis on constant 5 dBi gain in a deployed volume of 60 × 60 × 100 cm. On a finite ground plane, the antenna achieves a 3.2:1 bandwidth with VSWR <; 3 and an average gain of 0.5 dBi. A capacitive top hat loading was added to the antenna to improve matching and pattern stability. Full-wave simulations are verified with measurements of fabricated prototypes. Storability and deployability of the antenna design is confirmed with the UHF design.
Narrow bandwidth perfect absorber based on composite hybrid plasmonics (2023)

Surface plasmon polaritons (SPPs) have shown unprecedented potential for miniaturizing photonic devices beyond the optical diffraction limit. However, their high intrinsic loss from metal material has been a major barrier to practical applications. One effective approach to reducing their effective loss is to engineer SPPs coupling by designing hybrid plasmonic waveguides (HPWs). In this work, we first theoretically calculate and analyze the coupling modes in a composite HPW (CHPW), demonstrating that the long-range and short-range supermodes in CHPW correspond to two different SPPs at two metal layer interfaces. Next, we propose and demonstrate a narrow bandwidth perfect absorber based on CHPW structure. The absorber’s bandwidth is only 12.9 nm in the visible range and 6.67 nm in the near-infrared range. Our simulation results demonstrate that the CHPW’s SPPs coupling mechanism can be extended to localized surface plasmons (LSPs) in the proposed perfect absorber, enabling a low-loss mode that contributes to the narrow bandwidth. This suggests that the CHPW configuration could facilitate the development of more advanced low-loss, high-performance plasmonic devices.

Delineation of the patterns of activation of the human left atrium during sinus rhythm using a non-contact mapping system (2002)

The pattern of left atrial (LA) activation during sinus rhythm (SR) in humans has not been delineated. The authors used a non-contact mapping system to analyze the patterns of left atrial (LA) activation during sinus rhythm and pacing. The system is capable of simultaneously reproducing more than 3,000 electrograms, which are superimposed on a virtual left atrial endocardium. Data were recorded in sinus rhythm and during pacing from the high right atrium, coronary sinus os, and right atrial septum. The authors demonstrate that during sinus rhythm, the LA activates mainly through posterior septal fibers, adjacent to the ostia of the right pulmonary veins. This suggests that, in humans, anterior interatrial connections including Bachmann's bundle may be less important than previously recognized.
The trans-appendicular continent cystostomy technique (Mitrofanoff principle) (2008)

Introduction Since its brief description by Mitrofanoff in 1980, in a French pediatric journal,1 trans-appendicular continent cystostomy has become the most frequently-used operation in patients of all ages. Surprisingly, the technique has not been formally described, although it is often mentioned in technical reference books and numerous articles.2-8 Only Mitrofanoff ’s second publication in 20029 gave more technical details, but it was mainly oriented towards pediatrics (congenital malformations and neurologic bladders).
Navigation using carrier Doppler shift from a LEO constellation: TRANSIT on steroids (2021)

A new global navigation concept is studied that relies on carrier Doppler shift measurements from a large LEO constellation. This system could provide an alternative to pseudorange-based GNSS. The concept uses a high-fidelity model of received carrier Doppler shift. This model is used in a point-solution batch filter that simultaneously estimates eight unknowns: the three position vector components, receiver clock offset, three velocity vector components, and receiver clock offset rate. The filter uses eight or more measured Doppler shifts in its least-squares fit. A generalized Geometric Dilution of Precision (GDOP) analysis indicates that absolute position accuracies on the order of 1-5 meters and absolute velocity accuracies on the order of 0.01 m/sec to 0.05 m/sec may be achievable if the range-rate precision of the Doppler shift measurements is 0.01 m/sec. These accuracies are comparable to current pseudorange-based GNSS. Clock offset accuracy is on the order of 0.0001 to 0.0010 sec 1-.

A Reconfigurable Access Scheme for Critical Massive MTC Networks With Device Clusters (2022)

This paper presents a reconfigurable access scheme for critical massive machine-type communication networks where the access point (AP) is equipped with a large-scale antenna array, and devices can move and form clusters. Devices transmit alarm and regular packets to the AP by two-hop relay connections via cluster leaders. The delay constraints of alarm packets are guaranteed by considering jointly the effective bandwidth and effective capacity with the success probability threshold while the aggregate age of information (AoI) of regular packets is minimized by maximizing their AoI-weighted throughput. Simulation results show that the proposed algorithm outperforms random and round-robin scheduling in terms of minimizing AoI, and it guarantees the delay constraints in contrast to the baselines without delay consideration. Moreover, the proposed algorithm can dynamically distribute resources to serve alarm and regular packet transmissions based on the stringency of delay constraints.

Ag/ZnO Heterostructure Nanocrystals:  Synthesis, Characterization, and Photocatalysis (2007)

A high yield of the dimer-type heterostructure of Ag/ZnO nanocrystals with different Ag contents is successfully prepared through a simple solvothermal method in the absence of surfactants. The samples are characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, UV-vis spectroscopy, and IR spectroscopy. The results show that all samples are composed of metallic Ag and ZnO; Ag nanoparticles locate on the surface of ZnO nanorods; the binding energy of Ag 3d(5/2) for the Ag/ZnO sample with a Ag content of 5.0 atom % shifts remarkably to the lower binding energy compared with the corresponding value of pure metallic Ag because of the interaction between Ag and ZnO nanocrystals; the concentration of oxygen vacancy for the as-synthesized samples varies with the increasing Ag content, and the Ag/ZnO sample with a Ag content of 5.0 atom % has the largest density of oxygen vacancy. In addition, the relationship between their structure and photocatalytic property is investigated in detail. It is found that the photocatalytic property is closely related to its structure, such as heterostructure, oxygen defect, and crystallinity. The presence of metallic Ag nanoparticles and oxygen vacancy on the surface of ZnO nanorods promotes the separation of photogenerated electron-hole pairs and thus enhances the photocatalytic activity.
Optimizing CNN Accelerator With Improved Roofline Model (2020)

The external memory I/O bandwidth is the most common performance bottleneck for Convolutional Neural Network(CNN) inference accelerators. On the other hand, performance is also affected by many other factors such as the on-chip memory size and data scheduling strategies, making it difficult to identify the root cause of performance degradation. This paper proposes an improved roofline model specifically for the CNN accelerator, which provides a deep understanding of the bandwidth bottlenecks and points out the direction of optimization. Previous roofline models have focused on modeling and optimizing each layer, while neglecting some high-level optimizations (e.g. layer fusion and batch processing) that alleviate the bandwidth requirements. However, the uneven cross-layer bandwidth requirements can have a significant impact on the overall performance, and the combination of independently optimized layers does not necessarily result in an overall optimal solution. Our model is capable of modeling more complex data scheduling strategies and enables a larger design space than previous roofline models. We use the Xilinx CNN accelerator on ZU9 FPGA as an example for quantitative analysis and optimization. We apply the optimization method derived from the improved roofline model to the original design and ultimately achieve a 1.6x performance improvement. The derived optimization method effectively solves the severe temporary bandwidth overload problem in the original design that leads to the computational inefficiency.
An analysis of sigma-delta modulators as continuous systems (1993)

Introduces a method of analysis for sigma-delta analogue to digital converters based on replacing the nonlinear quantiser with a continuous element. Conventionally, analysis of sigma-delta modulation has been in the discrete domain, often treating the quantiser as a simple additive noise source, which has led to limited success in understanding the processes involved. However, the only truly discrete element in the circuit is the quantiser so if this could be represented accurately enough as a continuous element then a new approach to the analysis of Sigma Delta ADCs may be possible. A representation of the quantiser as a hyperbolic tangent function with a sufficiently steep gradient in the crossover region is proposed. A system of ordinary differential equations is the constructed to represent first, second and third order modulators and these equations are solved numerically, by the Runge Kutta method, for linear and nonlinear signal inputs. The results from this process are compared to those produced by a conventional simulation of sigma-delta modulation working on the same inputs. The results are presented in the form of time waveforms, showing the signal before quantisation, and the signal after decimation, for a range of input signals. It is shown that, for first and second order modulation at least, these results are compatible and that a basis for further analysis of sigma-delta modulation has been achieved.
Using the fault disturbance recorder as an operating aid for control room operators at the national load dispatch center of peninsular Malaysia (2001)

The greatest challenge facing the power system operators is during system disturbance. The operators must always be prepared to deal with unforeseen events and calamities. In order to assist the operators the NLDC (National Load Dispatch Center) is equipped with powerful software tools, and a fault disturbance recorder was installed in the control room to serve as an additional operating aid to the operators. This paper primarily focuses on the utilization of the disturbance recorder and how it has benefited the operators in helping them to arrive at some operational decisions. This paper also highlights some of the disturbance signatures that was obtained from observations of faults in the system using the disturbance recorder and how this has help the operator in his decision making process. The required skills and training for the operators in relation to the disturbance recorder are also discussed.
Quantitative Association Rules Mining Methods with Privacy-preserving (2005)

Considering the different size of quantitative attribute values and categorical attribute values in databases, we present two quantitative association rules mining methods with privacy-preserving respectively, one bases on Boolean association rules, which is suitable for the smaller size of quantitative attribute values and categorical attribute values in databases; the other one bases on partially transforming measures, which is suitable for the larger ones. To each approach, the privacy and accuracy are analyzed, and the correctness and feasibility are proven by experiments.
