Sub-wavelength bolometers: Uncooled platinum wires as infrared sensors (2011)

We present characterization results of microscopic platinum wires as bolometers. The wire lengths range from 16 μm down to 300 nm. Thus they are in many cases significantly smaller in size than the wavelength of the radiation from the 1200 K blackbody source they were exposed to. We observe a steep rise in both responsivity ℜ and detectivity D* with decreasing wire size, reaching ℜ = 3.1×10(4) V/W and D* = 2.7×10(9) cm Hz(1/2)/W at room temperature for a 300×300 nm(2) device. Two significant advantages of such small wires as bolometers are their low power requirement and fast response time. Our numerical estimations suggest response times in the order of nanoseconds for the smallest samples. They could help improve resolution and response of thermal imaging devices, for example. We believe the performance may be further improved by optimizing the design and operating parameters.

Experimental Study of Transport in Nanoscale Planar MOSFETs Near the Ballistic Limit (2004)

Using standard planar 22-nm-nMOS devices featuring a typical metalurgical length lower than 10 nm, we investigated the impact of nanoscale phenomena on device behavior. The data show that direct source-drain tunneling dominates the device leakage below 250 K and that carrier transport approaches the ballistic limit. The significant contribution of access resistance is revealed by low-temperature measurements below the superconducting transition of the cobalt disilicide contacts.

We demonstrate broadband low power supercontinuum generation in arsenic sulphide (As2S3) tapered fiber nanowires with an effective area ~0.8 μm2 and nonlinearity γ = 12,400 W−1 km−-1. Simulations showed good agreement between theory and experiment.
A large-signal equivalent circuit model for substrate-induced drain-lag phenomena in HJFETs (1996)

A large-signal HJFET model is developed for drain-lag phenomena caused by deep traps beneath the channel. The model is based on the self-backgating and Shockley-Read-Hall (SRH) statistics. It is shown by two-dimensional (2D) device simulation that electron capture in deep traps is much faster than electron emission under large-signal conditions; therefore, drain current exhibits different responses for rising and falling steps of applied voltage. In the circuit model, electron capture and emission in deep traps are expressed by a parallel circuit consisting of a diode and a resistor, which are physically deduced from SRH statistics. The model agrees well with the 2D simulation results and experimental current-transient data for large-signal voltage steps. In addition, this model accurately describes small-signal drain-conductance dispersion and temperature effects on the trapping phenomena.

The Importance of Moisture Control for EOT Scaling of Hf-Based Dielectrics (2009)

The role of moisture in atomic-layer-deposited (ALD) and dielectrics on equivalent oxide thickness (EOT) scaling is investigated in gate-first devices with physical-vapor-deposited TaN gates. By reducing the amount of present in the gate stack, the EOT increase during high-temperature spike annealing is reduced from . This was achieved by a premetallization degas at for . The origin of this improvement lies in the elimination of -related reoxidation of the interfacial . By means of temperature-programmed desorption measurements, it is found that the majority of the is desorbed between 200 and with activation energies between and . Furthermore, the concentration is dependent on the Hf concentration and nitridation. Non-nitrided with adsorbs twice as much as . Correspondingly, a significantly larger EOT increase is observed for with as compared to . In HfSiON, the desorbed concentration is independent of [Hf]. Finally, a strong metal dependency on the EOT regrowth is observed. With ALD TiN, the EOT increase after thermal treatment is found to be independent of the degas condition at .

Cloning and overexpression of the xylose isomerase gene from Burkholderia sacchari and production of polyhydroxybutyrate from xylose (2009)

A different organization for the xyl operon was found in different genomes of Burkholderia and Pseudomomas species. Degenerated primers were designed based on Burkholderia genomes and used to amplify the xylose isomerase gene (xylA) from Burkholderia sacchari IPT101. The gene encoded a protein of 329 amino acids, which showed the highest similarity (90%) to the homologous gene of Burkholderia dolosa. It was cloned in the broad host range plasmid pBBR1MCS-2, which partially restored growth and polyhydroxybutyrate production capability in xylose to a B. sacchari xyl- mutant. When xylA was overexpressed in the wild-type strain, it was not able to increase growth and polyhydroxybutyrate production, suggesting that XylA activity is not limiting for xylose utilization in B. sacchari.
A CMOS temperature sensor with a 3σ inaccuracy of ±0.5°C from -50°C to 120°C (2003)

A temperature sensor in 0.5/spl mu/m CMOS achieves an accuracy of /spl plusmn/0.5/spl deg/C (3/spl sigma/) from -50/spl deg/C to 120/spl deg/C. It combines chopping, dynamic element matching and curvature correction with calibration at room temperature. Calibration time has been reduced to less than 1s by using an onchip transistor to measure the die temperature.
May Bacterial Infections Trigger Bullous Pemphigoid? Case Report and Review of Literature (2021)

Bullous pemphigoid (BP) is an autoimmune blistering skin disease, mainly observed in the elderly. Infections have been suggested as possible disease triggers. However, infections may even heavily influence the disease clinical course and mortality. A 75-year-old woman was admitted to hospital for severe erythematosus blistering disease, accompanied by hyper-eosinophilia and hyper-IgE. The culture of bullous fluid was positive for <i>Enterococcus faecalis</i>, the blood culture was positive for <i>Staphylococcus aureus</i>, and the urine culture was positive for <i>Proteus mirabilis</i> and <i>Escherichia coli.</i> Moreover, circulating anti-BP180 IgG was present and the histopathological/ultrastructural examination of a lesional skin biopsy was compatible with BP. High eosinophil levels (up to 3170/µL) were found throughout the clinical course, while values below 1000/µL were associated with clinical improvement. The total IgE was 1273 IU/mL, and specific anti-G/V-penicillin/ampicillin IgE antibodies were positive. The patient had a complete clinical recovery in two months with methyl-prednisolone (40 then 20 mg/day) and low-dose azathioprine (50 mg/day) as a steroid-sparing agent. The steroid treatment was tapered until interruption during a one-year period and intravenous immunoglobulins have been administered for three years in order for azathioprine to also be interrupted. The patient stopped any treatment five years ago and, in this period, has always been in good health. In this case, the contemporaneous onset of different bacterial infections and BP is suggestive of bacterial infections acting as BP trigger(s), with allergic and autoimmune pathways contributing to the disease pathogenesis.

Learning from Demonstration: Situation-Adaptive Lane Change Trajectory Planning for Automated Highway Driving (2020)

Trajectory planning is one of the key challenges to enable automated driving system on the road. In structured highway environment, lane change trajectory planning algorithm for automated driving has generally been formulated as optimizing complex cost functions which should be manually specified and tuned by experts. However, considering the highly dynamic environment in highway automation, a wide variety of cost functions may be designed to work in different driving situations, making the hand-tuning a recurring process and requires rich experience. This research proposes the driving situation-adaptive lane change trajectory planning approach by learning from expert demonstrations. Specifically, in offline learning process, the trajectory planning cost functions database is constructed by correlating the driving situation assessment result with the corresponding situation-specific planning cost function which can be learned from expert demonstration trajectory automatically via feature-based inverse reinforcement learning technique. In online trajectory optimization process, the lane change environment is evaluated by Bayesian Network firstly and then the situation-dependent cost function can be synthesized from database. The final planned lane change trajectory can be effectively calculated by optimizing the synthesized cost function. Simulation experiments in different driving environments demonstrate that the proposed method is capable of learning distinct cost functions and planning driving situation-adaptive lane change trajectory using data from expert demonstrated trajectories.
Antitumor Effect of SN-38–Releasing Polymeric Micelles, NK012, on Spontaneous Peritoneal Metastases from Orthotopic Gastric Cancer in Mice Compared with Irinotecan (2008)

7-Ethyl-10-hydroxy-camptothecin (SN-38), an active metabolite of irinotecan hydrochloride (CPT-11), has potent antitumor activity. Moreover, we have reported the strong antitumor activity of NK012 (i.e., SN-38-releasing polymeric micelles) against human cancer xenografts compared with CPT-11. Here, we investigated the advantages of NK012 over CPT-11 treatment in mouse models of gastric cancer with peritoneal dissemination. NK012 or CPT-11 was i.v. administered thrice every 4 days at their respective maximum tolerable doses (NK012, 30 mg/kg/day; CPT-11, 67 mg/kg/day) to mice receiving orthotopic transplants of gastric cancer cell lines (44As3Luc and 58As1mLuc) transfected with the luciferase gene (n = 5). Antitumor effect was evaluated using the photon counting technique. SN-38 concentration in gastric tumors and peritoneal nodules was examined by high-performance liquid chromatography (HPLC) 1, 24, and 72 hours after each drug injection. NK012 or CPT-11 distribution in these tumors was evaluated using a fluorescence microscope on the same schedule. In both models, the antitumor activity of NK012 was superior to that of CPT-11. High concentrations of SN-38 released from NK012 were detected in gastric tumors and peritoneal nodules up to 72 hours by HPLC. Only a slight conversion from CPT-11 to SN-38 was observed from 1 to 24 hours. Fluorescence originating from NK012 was detected up to 72 hours, whereas that from CPT-11 disappeared until 24 hours. NK012 also showed antitumor activity against peritoneal nodules. Thus, NK012 showing enhanced distribution with prolonged SN-38 release may be ideal for cancer treatment because the antitumor activity of SN-38 is time dependent.
Molecular Typing ofNeisseria gonorrhoeaeCausing Repeated Infections: Evolution of Porin during Passage within a Community (1999)

Thirty-three Neisseria gonorrhoeae isolates from 15 persons infected multiple times with the same serovar were compared using por gene sequencing, opa-typing, and arbitrarily primed-polymerase chain reaction. All three molecular techniques were more discriminatory than serotyping and identified differences between some isolates belonging to the same serovar. Although there were differences among Por sequences within some serovars, 10 of 15 subjects became reinfected with gonococci expressing identical Por proteins. Sequence analysis of por genes revealed evidence of horizontal genetic exchange and point mutations in potential surface-exposed regions during passage in the community.
Influence of dry etching on nitride semiconductor Schottky characteristics (2006)

GaN has attractive physical properties, such as high saturation velocity, high breakdown electric field and good thermal conductivity. Owing to these inherent material properties, GaN and related alloys are attractive materials for high-speed, high-power and high-temperature electronic devices. For production process of electron devices such as recessed gate-AlGaN/GaN FET, a dry etching process is indispensable. Therefore, degradation of electrical properties due to the etching damage has to be considered to improve the device performance. In this work, influences of dry etching process for GaN on the electrical properties and the chemical properties of the surface were investigated.
Highly Stable, Near‐Unity Efficiency Atomically Flat Semiconductor Nanocrystals of CdSe/ZnS Hetero‐Nanoplatelets Enabled by ZnS‐Shell Hot‐Injection Growth (2019)

Colloidal semiconductor nanoplatelets (NPLs) offer important benefits in nanocrystal optoelectronics with their unique excitonic properties. For NPLs, colloidal atomic layer deposition (c-ALD) provides the ability to produce their core/shell heterostructures. However, as c-ALD takes place at room temperature, this technique allows for only limited stability and low quantum yield. Here, highly stable, near-unity efficiency CdSe/ZnS NPLs are shown using hot-injection (HI) shell growth performed at 573 K, enabling routinely reproducible quantum yields up to 98%. These CdSe/ZnS HI-shell hetero-NPLs fully recover their initial photoluminescence (PL) intensity in solution after a heating cycle from 300 to 525 K under inert gas atmosphere, and their solid films exhibit 100% recovery of their initial PL intensity after a heating cycle up to 400 K under ambient atmosphere, by far outperforming the control group of c-ALD shell-coated CdSe/ZnS NPLs, which can sustain only 20% of their PL. In optical gain measurements, these core/HI-shell NPLs exhibit ultralow gain thresholds reaching ≈7 µJ cm<sup>-2</sup> . Despite being annealed at 500 K, these ZnS-HI-shell NPLs possess low gain thresholds as small as 25 µJ cm<sup>-2</sup> . These findings indicate that the proposed 573 K HI-shell-grown CdSe/ZnS NPLs hold great promise for extraordinarily high performance in nanocrystal optoelectronics.
Yield Limits of Plates at Extremely High Heat Flux (1998)

For heat fluxes ranging above 10 MW/m2 or so, solid surfaces usually experience large thermal stresses and degradation of mechanical properties. The resulting mechanical failure of such surfaces is a primary limitation to the design of thermal systems at extremely high heat flux. This investigation considers the elastic stresses in circular plates subjected to extremely high heat fluxes. A gaussian distributed heat load is applied to one surface of the plate and the heat flux at which yielding occurs is identified. Several candidate materials are examined, accounting for the temperature dependence of yield strength and other properties. The mechanical boundary conditions on the plate are varied. Figures of merit are given for the high flux performance of a number of materials.
Re-crystallization Behavior of Amorphous Layer in Hydrocarbon Molecular Ion Implanted Region Using Flash Lamp Annealing (2018)

We have developed hydrocarbon molecular ion implanted epitaxial wafers for advanced CMOS image sensors. The hydrocarbon molecular ion implanted region has the highest gettering capability for metallic impurities and plays a barrier role for-diffused oxygen atoms from CZ grown Si substrate. In addition, implanted hydrogen atoms diffuse out and passivate process-induced defects in device process. It is previously reported that high-dose hydrocarbon molecular ion implantation enhances these characteristics even more. However in high-dose implantation condition, stacking faults are formed in epitaxial layer. In this study, the flash lamp annealing is investigated as recovery annealing after high-dose implantation. The flash lamp annealing is expected to change the re-crystallization behavior of amorphous layer and suppress the formation of stacking faults in epitaxial layer without diffusion of hydrogen atoms from implanted region. Consequently, by the flash lamp annealing after high-dose implantation the stacking faults in epitaxial layer are perfectly suppressed. Furthermore, high concentration hydrogen remains in implanted region after FLA and epitaxial growth process due to change of defect morphology. Without recovery annealing after high-dose implantation, amorphous layer is re-crystallized in ramp-up time of epitaxial growth process and clamshell type defects are formed. Conversely, by flash lamp annealing high density small defect are formed. These high density small defects are contributed to remain hydrogen atoms in implanted region.
Murine Monoclonal Antibodies Biologically Active against the Amino Region of HIV-1 gp120: Isolation and Characterization (2000)

The human immunodeficiency virus (HIV)-1 envelope glycoprotein is synthesized as a precursor (gp160) and subsequently cleaved to generate the external gp120 and transmembrane gp41 glycoproteins. Both gp120 and gp41 have been demonstrated to mediate critical functions of HIV, including viral attachment and fusion with the cell membrane. The antigenic variability of the HIV-1 envelope glycoprotein has presented a significant problem in the design of appropriate and successful vaccines and offers one explanation for the ability of HIV to evade immune surveillance. Therefore, the development and characterization of functional antibodies against conserved regions of the envelope glycoprotein is needed. Because of this need, we generated a panel of murine monoclonal antibodies (MuMabs) against the HIV-1 envelope glycoprotein. To accomplish this, we immunized Balb/C mice with a recombinant glycoprotein 160 (gp160) that was synthesized in a baculovirus expression system. From the growth-positive hybridomas, three MuMabs were generated that demonstrated significant reactivity with recombinant gp120 but failed to show reactivity against HIV-1 gp41, as determined by enzyme-linked immunosorbent assay (ELISA). Using vaccinia constructs that synthesize variant truncated subunits of gp160, we were able to map reactivity of all three of the Mabs (ID6, AC4, and AD3) to the first 204 residues of gp120 (i.e., the N terminus of gp120) via Western blot analysis. Elucidation of the epitopes for these Mabs may have important implications for inhibition of infection by HIV-1. Our initial attempts to map these Mabs with linear epitopes have not elucidated a specific antigenic determinant; however, several physical characteristics have been determined that suggest a continuous surface epitope. Although these antibodies failed to neutralize cell-free or cell-associated infection by HIV-1, they did mediate significant antibody-dependent cellular cytotoxicity (ADCC) activity, indicating potential therapeutic utility. In summary, these data suggest the identification of a potentially novel site in the first 200 aa of gp120 that mediates ADCC.
Mesh Ensemble Motion Graphs (2007)

We explore the use of space-time cuts to smoothly transition between stochastic mesh animation clips involving numerous deformable mesh groups while subject to physical constraints. These transitions are used to construct Mesh Ensemble Motion Graphs for interactive data-driven animation of high-dimensional mesh animation datasets, such as those arising from expensive physical simulations of deformable objects blowing in the wind. We formulate the transition computation as an integer programming problem, and introduce a novel randomized algorithm to compute transitions subject to geometric nonpenetration constraints. We present examples for several physically based motion datasets, with real-time display and optional interactive control over wind intensity via transitions between wind levels. We discuss challenges and opportunities for future work and practical application.
