A thin AMC-combined loop antenna applicable to wearable devices (2017)

This paper suggests a printed loop antenna having robust impedance matching and electromagnetic radiation, and low EM effect on the human body. This is achieved by developing a thin and small-area artificial magnetic conductor (AMC) supporting the loop radiator. This outperforms the conventional AMC antennas in terms of thickness and radiation. Besides, this has a low SAR below 1 W/kg.

Development of Improved Cellulase Mixtures in a Single Production Organism (2007)

Economical conversion of lignocellulosic biomass to sugars, ethanol or other chemical feedstocks requires an optimization of the enzymatic breakdown of plant cell walls to monosaccharides. Corn Stover was converted to glucose by dilute acid pretreatment followed by enzymatic digestion with broths containing novel mixtures of proteins expressed in Trichoderma reesei. Optimization included improvement of the pretreatment, alteration of the expressed suite of enzymes, and increased productivity of the expression host, which resulted in significant reduction in the enzyme cost for utilization of lignocellulosic biomass for the production of fuels and chemicals.
Complementary GaAs junction-gated heterostructure field effect transistor fabrication for integrated circuits (1994)

A new GaAs junction-gated complementary logic technology that integrates a modulation doped p-channel heterostructure field effect transistor (pHFET) and a fully ion implanted n-channel JFET has recently been fabricated. High-speed, low-power operation has been demonstrated with loaded ring oscillators that show gate delays of 179 ps/stage for a power-delay product of 28 fJ at 1.2 V operation and 320 ps/stage and 8.9 fJ at 0.8 V operation. The principal advantages of this technology include the ability to independently set the threshold voltage of n- and p-channel devices and to independently design the pHFET for high performance. A self-aligned refractory gate process based on tungsten and tungsten silicide gate metal has been used to fabricate the FETs. Novel aspects of the fabrication include the simultaneous formation of non-alloyed, refractory ohmic contacts for the junction gates and the formation of shallow p-n junctions by ion implantation.
Motion Blur-Based State Estimation (2015)

Motion measurement increasingly deploys image sensors such as charge-coupled device and CMOS arrays, driven by their ever-improving resolution, response time, noise level, and cost. The typical usage is to operate an image sensor and the associated optics as a sampler, by taking a series of high-speed sharp pictures to infer motion. Image blur is treated as an undesirable artifact, to be removed using shorter exposure times or image processing techniques such as deblurring. We have previously shown that dynamic information embedded in image blur may be exploited for model identification in frequency ranges well beyond the Nyquist frequency. In this brief, we investigate the state estimation problem using motion blur. We pose the problem as a minimization, estimating the state at the start of each (slow) sampling period based on the observed motion blur. We show that the local convexity of the minimization corresponds to a generalized observability criterion. This method is compared with other techniques, including the conventional centroid-based method, and that based on the use of multiple image moments. The simulation and experimental results demonstrate the fast response and robustness of the proposed scheme in the presence of synthetic stray light.
Biodegradable Breast Tissue Marker Clip (2020)

Biodegradable soft tissue biopsy clips have been developed as implants with the potential to serve as visual markers for regions suspected to contain tumor growth in the breast. These clips are multidimensional tissue markers with better biocompatibility and imaging features. The clips were prepared using biodegradable polymers, poly(l-lactide-<i>co</i>-ε-caprolactone) and methoxy polyethylene glycol-<i>co</i>-l-lactide, that contain iodixanol or barium sulfate as contrast agents; they are further coated with hyaluronic acid or sodium alginate hydrogels. The clips were visible by imaging modalities such as mammography, ultrasound, and magnetic resonance imaging after implantation in Sprague-Dawley rats. The clips stayed intact in the implantation cavity of the animal for more than 3 months with unpretentious changes in their lengths and morphology. The histopathological examination of implanted clips revealed no signs of systemic toxicity in the rats. Overall, the interpretation of the results reveals that the developed clips can be a potential replacement for metal-based markers.
From the Direct Observation of a PAA‐Based Binder Using STEM‐VEELS to the Ageing Mechanism of Silicon/Graphite Anode with High Areal Capacity Cycled in an FEC‐Rich and EC‐Free Electrolyte (2022)

Abstract The polymer binder is a key constituent of silicon‐based electrode formulation for lithium‐ion batteries. However, its extremely difficult visualization in fresh electrodes becomes completely impossible in cycled electrodes. Here, the combination of scanning transmission electron microscopy—valence electron energy‐loss spectroscopy with the use of a specific electrolyte solvent composition (a mixture of dimethyl carbonate and fluoroethylene carbonate, without ethylene carbonate) allows the visualization, for the first time, of the binder in silicon‐based electrodes, even cycled up to 100 cycles. Such an observation is possible as the only solid degradation product of this electrolyte is LiF, as confirmed by quantitative 7 Li and 19 F magic angle spinning nuclear magnetic resonance. The electrodes, based on a blend of silicon and graphite, have a very high surface capacity, 6.5 mAh cm −2 , which makes them meaningful for electric vehicle applications. The performance is appreciable, in particular the first cycle efficiency approaching that of commercial graphite electrodes, as well as the capacity retention in full cell, versus LiNi 0.5 Mn 0.3 Co 0.2 O 2 , 60% after 100 cycles. This work also illustrates the ultimate state of destructuration of silicon after long cycling, which invites new ways of thinking about the design of this material.

On the reduction of base resistance in GaN-based heterojunction bipolar transistors (2002)

The high resistivity of p-type GaN presents a significant barrier to the development of bipolar electronic and optoelectronic devices. Specifically with regard to N-p-n heterojunction bipolar transistors (HBTs), the resistance of the p-type base manifests itself in three distinct ways: the intrinsic base resistance under the active region of the device, as well as the base access resistance, consisting of contact resistance and extrinsic base resistance. Methods of combating each of these parasitics are presented. A new type of low resistance metal semiconductor contact is proposed and demonstrated, based on strong internal electric fields induced by polarization effects. Results on photoelectrochemical etching as a low damage, dopant selective technique of etching GaN-based HBT structures are presented. Very smooth interfaces and low contact resistances are obtained in GaN/SiC HBT structures. Another etch technique involves crystallographic etching of GaN, producing undercut cross-sections. This enables the use of self-aligned base contacts, further reducing base access resistance. Finally, increasing the conductivity of the p-type material itself is realized by the use of AlGaN/GaN superlattices. Lateral hole conductivity is improved in these structures, but effective electron transport perpendicular to the layers remains to be proven.

Comparative study of conventional and hybrid blocking layers for solid-state dye-sensitized solar cells (2011)

In hybrid solar cells a blocking layer between the transparent electrode and the mesoporous titanium dioxide is used to prevent short-circuits between the hole-conductor and the front electrode. The conventional approach is to use a compact film of titanium dioxide. This layer has to be of optimum thickness: it has to cover the rough surface of the anode material completely while keeping it as thin as possible since the layer acts as an ohmic resistance itself. A competitive alternative arises when using an amphiphilic diblock copolymer as a functional template to produce thin, hybrid films containing a conducting titanium dioxide network embedded in an insulating ceramic material. These hybrid films can be produced much thinner compared to the conventional approach and, hence, they possess a 32% higher conductivity. The conventional and the hybrid blocking layer are characterized by conductive scanning probe microscopy and macroscopic conductance measurements. Additionally, the functionality of both blocking layers in solid-state dye-sensitized solar cells, as tested with current-voltage measurements, is verified.
View Definition and Generalization for Database Integration in a Multidatabase System (1984)

Access to a heterogeneous distributed collection of databases can be simplified by providing users with a logically integrated interface or global view. There are two aspects to database integration. Firstly, the local schemas may model objects and relationships differently and, secondly, the databases may contain mutually inconsistent data. This paper identifies several kinds of structural and data inconsistencies that might exist. It describes a versatile view definition facility for the functional data model and illustrates the use of this facility for resolving inconsistencies. In particular, the concept of generalization is extended to this model, and its importance to database integration is emphasized. The query modification algorithm for the relational model is extended to the semantically richer functional data model with generalization.
Infusion of Human Umbilical Cord Blood Ameliorates Neurologic Deficits in Rats with Hemorrhagic Brain Injury (2005)

Umbilical cord blood is a rich source of hematopoietic stem cells. It is routinely used for transplantation to repopulate cells of the immune system. Recent studies, however, have demonstrated that intravenous infusions of umbilical cord blood can ameliorate neurologic deficits associated with ischemic brain injury in rodents. Moreover, the infused cells penetrate into the parenchyma of the brain and adopt phenotypic characteristics typical of neural cells. In the present study we tested the hypothesis that the administration of umbilical cord blood can also diminish neurologic deficits caused by intracerebral hemorrhage (ICH). Intracerebral hemorrhage is a major cause of morbidity and mortality, and at the present time there are no adequate therapies that can minimize the consequences of this cerebrovascular event. ICH was induced in rats by intrastriatal injections of collagenase to cause bleeding in the striatum. Twenty-four hours after the induction of ICH rats received intravenous saphenous vein infusions of human umbilical cord blood (2.4 x 10(6) to 3.2 to 10(6) cells). Animals were evaluated using a battery of tests at day 1 after ICH, but before the administration of umbilical cord blood, and at days 7, and 14 after ICH (days 6 and 13, respectively, after cord blood administration). These tests included a neurological severity test, a stepping test, and an elevated body-swing test. Animals with umbilical cord blood infusions exhibited significant improvements in (1) the neurologic severity test at 6 and 13 days after cord blood infusion in comparison to saline-treated animals (P < 0.05); (2) the stepping test at day 6 (P < 0.05); and (3) the elevated body-swing test at day 13 (P< 0.05). These results demonstrate that the administration of human umbilical cord blood cells can ameliorate neurologic deficits associated with intracerebral hemorrhage.
Conditional Neural Language Models for Multimodal Learning and Natural Language Understanding (2018)

In this thesis we introduce conditional neural language models based on log-bilinear and recurrent neural networks with applications to multimodal learning and natural language understanding. We first introduce a LSTM encoder for learning visual-semantic embeddings for ranking the relevance of text to images in a joint embedding space. Next we introduce three log-bilinear models for generating image descriptions that integrate both additive and multiplicative interactions. Beyond image conditioning, we describe a multiplicative conditional neural language model for learning distributed representations of attributes and meta data. Our model allows for contextual word relatedness comparisons through decompositions of a word embedding tensor. Finally we show how we can abstract the skip-gram model for learning word representations to a conditional recurrent neural language model for unsupervised learning of sentence representations. We introduce a family of models called contextual encoder-decoders and demonstrate how our models can be used to induce generic sentence representations as well as unaligned generation of short stories conditioned on images. This thesis closes by highlighting several open areas of future work.
Guest Editors’ Introduction: Special Issue on Architecture Advances Enabled by Emerging Technologies (2019)

As we approach the twilight of Moore’s Law and dimensional scaling of advanced CMOS technologies, many beyond-CMOS logic and memory device technologies are being explored. In order to fully exploit the promises of these emerging technologies, we need major simultaneous advances in architecture and design, especially for the new computing workloads in future intelligent IoT systems. This special issue presents five articles that describe emerging opportunities for such technologydesign- architecture co-optimizations.
A packed building-block compensator (TETRIS-RT) and feasibility for IMRT delivery (2005)

A packed building-block compensator (TETRIS-RT) for IMRT (Intensity Modulated Radiation Therapy) delivery has been proposed. The compensator contains two kinds of cubic blocks: x-ray absorbing blocks for intensity modulation and x-ray transparent blocks for packing. The packed blocks are placed inside a rectangular enclosure, and the resulting compensators can be attached to a linac gantry head through a rotatable mount for efficient multiportal IMRT. A fabrication device and a sorting device were also developed. The fabrication device can automatically stack two different types of blocks to produce a compensator while the sorting device can separate each type of the blocks for subsequent fabrication. Preliminary film experiments have shown that an additional leakage dose through the rounded edges of the ten-layered x-ray absorbing blocks was 0.9% of the delivered dose with a total shielded dose ratio of 10% including the peak leakage. It was observed that the proposed compensator may provide a highly modulated dose distribution. This suggests its feasibility for IMRT delivery with a limit of 1cm×1cm spatial resolution at isocenter in the plane perpendicular to the beam, and larger discrete intensity steps of approximately 10% compared to conventional compensators. Advantages of the proposed compensator include that the compensator blocks are reusable and can be utilized to automatically and quickly fabricate a compensator, thereby minimizing human labor.
Advanced UHP lamps for projection systems (2003)

Projection systems for large screens have made tremendous progress during the last years, both in terms of performance and size reduction. Improved UHP lamp systems made a major contribution to enable the new generation of projectors. The arc gap is reduced to 1 mm only and allows a high collection efficiency in the projector. At the same time the lamp wattage was increased. In this way, today's projectors can create high-quality XGA pictures with more than 3000 screen lumens using one single 200 W UHP-lamp. Such a projector reaches an efficiency of more than 10 screen lumens per watt electrical input power. The volume of lamp and driver has been reduced by one order of magnitude during the last six years. This was possible by recent progress that has been achieved on the ignition of the lamp. By using a UV-enhancer cavity in the lamp seal and an additional antenna the ignition voltage could be reduced from 20 kV to below 5 kV. This allows more compact drivers and is ideal for miniaturizing projectors. A new optical concept allows for extremely compact reflector systems: A dichroic coating applied to one half of the UHP burner focuses all light into one hemisphere. Additionally 20-30% more light can be collected in systems with high optical demands. Making use of both the reduced ignition voltage and the new optical concept a reduction of the volume of lamp and driver by a factor of 10 has been realized.
Submodular Decomposition Framework for Inference in Associative Markov\n Networks with Global Constraints (2011)

In the paper we address the problem of finding the most probable state of\ndiscrete Markov random field (MRF) with associative pairwise terms. Although of\npractical importance, this problem is known to be NP-hard in general. We\npropose a new type of MRF decomposition, submodular decomposition (SMD). Unlike\nexisting decomposition approaches SMD decomposes the initial problem into\nsubproblems corresponding to a specific class label while preserving the graph\nstructure of each subproblem. Such decomposition enables us to take into\naccount several types of global constraints in an efficient manner. We study\ntheoretical properties of the proposed approach and demonstrate its\napplicability on a number of problems.\n
A Novel Wireless Sensor Network Architecture for Crowd Disaster Mitigation (2012)

Disasters aroused due to dynamic movement of large, uncontrollable crowds are ever increasing. The inherent realtime dynamics of crowd need to be tightly monitored and alerted to avoid such disasters. Most of the existing crowd monitoring systems is difficult to deploy, maintain, and dependent on single component failure. This research work proposes novel network architecture based on the key technologies of wireless sensor network and mobile computing for the effective prediction of causes of crowd disaster particularly stampedes in the crowd and thereby alerting the crowd controlling station to take appropriate actions in time. In the current implemented version of the proposed architecture, the smart phones act as wireless sensor nodes to estimate the probability of occurrence of stampede using data fusion and analysis of embedded sensors such as tri-axial accelerometers, gyroscopes, GPS, light sensors etc. The implementation of the proposed architecture in smart phones provides light weight, easy to deploy, context aware wireless services for effective crowd disaster mitigation.
An overview of MPEG-4 object-based encoding algorithms (2002)

Describes several object-based encoding issues and provides solutions based on the MPEG-4 coding standard. Specifically, we first consider the general problem of object-based rate control and the allocation of bits among each object. Going a step further, we then discuss the issues related to the allocation of bits between shape and texture, and propose a method to model the rate distortion characteristics of the shape. Finally, we describe some preliminary work that we have been doing towards optimizing the tradeoff in spatial and temporal quality. For object-based coding, it is believed that significant coding gains can be achieved.
THE TARGET-CHEMOTHERAPY DIRECTED BY THE RADIATION (2005)

The target-chemetherpy directed by the radiation was tested by the two methods; 1) facilitate the carboplatin; and 2) the capsules that is decomposed by irradiation IN VITRO. The human leukemic cell (OCI/M2) cultured in RPMI 1640 was treated by the 0.5 Gy of 60 Co γ ray after the 4μmol of carboplatin administration. The uptake of carboplatin expressed as Pt signal was measured by the micro PIXE camera. The increased uptake of carboplatin was observed in the cell. There was also an increased uptake of Cu . The chelating of Cu resulted in the maximum uptake of carboplatin under the combined treatment of radiation and carboplatin. As for the capsules, it was prepared by polymerizing the alginate by CaCl 2 , whose core was carboplatin. The 0.5 Gy irradiation was performed to the capsules. The carboplatin's emission was observed using a micro PIXE camera. As a result, the carboplatin was emitted from capsules, which was almost 10 %. Those two methods (increased uptake of carboplatin by low dose irradiation and the capsules decomposed by irradiation) is considered to be useful for the better therapeutic gain and less adverse effect.
