A Civil Rights Task: Removing Barriers to Employment of Ex-Convicts (2004)

This article explores the range and scope of the legal impediments to ex-offenders' employment, but it also has other goals. A question is raised as to what has prompted the imposition of the civil disabilities imposed on ex-offenders regarding employment, and why they are so widespread and unchanging despite a wealth of scholarly objection to their maintenance. A very important question, not raised by other scholars on the topic, will be raised here-namely, should traditional civil rights organizations, concerned with improving the conditions for black Americans, begin to treat this problem as one that is in urgent need of law reform? If so, what resistances will such organizations meet, and what strategies are appropriate responses?
Shape memory alloys as strain sensors in composites (2006)

Composites of shape memory alloys (SMA) with a matrix have been widely studied to suppress propagating damage of the matrix, where the embedded SMA is used as an actuator. We use the embedded SMA wire in composites both as an actuator and as a strain sensor. The possibilities of using the SMA wire as a strain sensor to obtain an actuation trigger signal for damage suppression were investigated using the variation of the SMA electric resistance. We determined that the electric resistance variation of the SMA wire is correlated with the strain. The temperature dependence of the correlation, which can be reduced by a compensation method, is also discussed.
Organic light-emitting diodes under high currents explored by transient electroluminescence on the nanosecond scale (2011)

We investigate organic light-emitting diodes (OLEDs) comprising the singlet emitter system 4-dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4H-pyran (DCM) doped into aluminium tris(8-hydro-xyquinoline) (Alq${}_{3}$) at high excitation densities. With the OLED active area reduced to $100\ifmmode\times\else\texttimes\fi{}100\phantom{\rule{0.28em}{0ex}}\ensuremath{\mu}$m${}^{2}$, current densities up to 800 A/cm${}^{2}$ are achieved in pulsed operation. These devices exhibit an intense electroluminescence (EL) turn-on peak on the nanosecond time scale. With the help of streak camera measurements, we prove that the steady state EL of the fluorescent OLEDs is reduced due to singlet-triplet quenching. We demonstrate that short electrical pulses with a rise time of 10 ns make the separation of singlet emission and singlet-triplet quenching in time domain possible. By modeling the singlet and triplet population dynamics in the emission layer, we find that the triplet-triplet annihilation-rate coefficient in doped fluorescent materials is triplet-density dependent at high excitation density. The increased triplet lifetime usually observed in host:guest systems due to triplet trapping on guest molecules vanishes at high current densities. An increase in current density leads to an increased triplet-triplet annihilation rate, while the triplet density in the emission layer stays constant.
The oral microbiome (2017)

The human microbiome is receiving a great deal of attention as its role in health and disease becomes ever more apparent. The oral microbiome, perhaps due to the ease with which we can obtain samples, is arguably the most well-studied human microbiome to date. It is obvious, however, that we have only just begun to scratch the surface of the complex bacterial and bacterial-host interactions within this complex community. Here, we describe the factors which are known to influence the development of the seemingly globally conserved, core, oral microbiome and those which are likely to be responsible for the observed differences at the individual level. We discuss the paradoxical situation of maintaining a stable core microbiome which is at the same time incredibly resilient and adaptable to many different stresses encountered in the open environment of the oral cavity. Finally, we explore the interactions of the oral microbiome with the host and discuss the interactions underlying human health and disease.
Anti-immunoglobulin E treatment decreases worm burden and egg production in Schistosoma mansoni-infected normal and interferon gamma knockout mice. (1994)

The immunoglobulin E (IgE) response is generally considered an essential component of the host defense against parasitic helminths such as Schistosoma mansoni. In contrast, work on antischistosome vaccines suggests that interferon gamma (IFN-gamma) is the critical immune mediator for vaccine-induced immunity to the parasite. In this study, the total IgE response to a primary S. mansoni infection was suppressed by anti-IgE treatment in both normal mice and in mice with defective IFN genes (gene knockout [GKO]). Reduction of the IgE response resulted in decreased worm burden and a decrease in the number of eggs produced per worm in both normal and GKO mice. Whereas anti-IgE treatment also resulted in reduced hepatosplenomegaly, granulomas around existing schistosome eggs showed normal cellularity. Serum interleukin 4 levels fell in response to the reduction in serum IgE as well. The data suggest that IgE plays a detrimental, rather than beneficial, role for the host in schistosomiasis. Furthermore, the absence of IFN-gamma was found to be of little consequence to the host-response to adults or eggs in a primary schistosome infection.
Action Completion: A Temporal Model for Moment Detection (2018)

We introduce completion moment detection for actions - the problem of locating the moment of completion, when the action's goal is confidently considered achieved. The paper proposes a joint classification-regression recurrent model that predicts completion from a given frame, and then integrates frame-level contributions to detect sequence-level completion moment. We introduce a recurrent voting node that predicts the frame's relative position of the completion moment by either classification or regression. The method is also capable of detecting incompletion. For example, the method is capable of detecting a missed ball-catch, as well as the moment at which the ball is safely caught. We test the method on 16 actions from three public datasets, covering sports as well as daily actions. Results show that when combining contributions from frames prior to the completion moment as well as frames post completion, the completion moment is detected within one second in 89% of all tested sequences.
Psychosocial functioning in patients with personality disorders: a review of the evidence-based research studies literature. (2008)

Evidence based practice  is a complex aim to achieve in the area of Psychiatry, and even more complex, when aspiring to explain personality disorders, theoretical constructs that in themselves are fully vague, and that have always been a source of confusion and debate between mental health professionals. This confusion, as much as anything, justifies the need to empirically back the areas of treatment that can be supported by evidence, without disregarding the unique elements of clinical practice such as the professional’s own experience, and the patient’s preferences and values. The authors offere a brief revision of the most relevant literature regarding psychosocial dysfunction on PD´s. Empirically investigations remain scarce, but the existing findings seem to support that impaired functioning, especially social functioning, is an enduring component of PD’s.
An improved LPP algorithm (2012)

Discriminant Locality Preserving Projection (DLPP) has been successfully used as a dimensionality reduction technique to many classification problems, which incorporate discriminant information into Locality Preserving Projection (LPP) to improve recognition rate. However, in order to avoid small sample size problem, DLPP needs to reduce dimensions, which will lose some important discriminative information. Direct Linear Discriminant Analysis (DLDA) can solve the problem by diagonalization. Inspired by DLDA, we propose a novel method of improvement algorithm, which incorporate DLDA into LPP. Compared with DLPP and LPP, this algorithm not only preserves more effective discriminative information, but also solves the small sample size problem in dimensionality reduction. It also improves light sensitivity when distinguish an uneven illumination image. The modified LPP algorithm achieves better result than DLPP and LPP in face recognition.
Preparation and Performance of Pd Particles Encapsulated in Block Copolymer Nanospheres as a Hydrogenation Catalyst (2000)

Triblock nanospheres with hydroxylated polyisoprene (PHI) coronas, cross-linked poly(2-cinnamoyloxyethyl methacrylate) shells, and poly(acrylic acid) (PAA) cores were prepared following a method described previously. Equilibrating such nanospheres with a PdCl2 solution in methanol enabled the loading of Pd2+ into the PAA cores of the nanospheres. After the excess PdCl2 in the methanol phase was removed, Pd(II) inside the nanosphere cores was reduced with hydrazine to yield Pd nanoparticles. Such encapsulated Pd particles were dispersed in methanol or water, which solubilized PHI. Like Pd black, the nanosphere-encapsulated Pd nanoparticles catalyzed the hydrogenation of alkenes. The need for the reactant(s) to diffuse into and products to diffuse out of the encapsulating nanospheres expectedly slowed the catalytic reactions. The more interesting aspect had been in our ability to modify the activity of the Pd catalyst via changing the pH and thus the conformation of the encapsulating polymer chains.
Feasibility of using fMRI to study mothers responding to infant cries (1999)

While parenting is a universal human behavior, its neuroanatomic basis is currently unknown. Animal data suggest that the cingulate may play an important function in mammalian parenting behavior. For example, in rodents cingulate lesions impair maternal behavior. Here, in an attempt to understand the brain basis of human maternal behavior, we had mothers listen to recorded infant cries and white noise control sounds while they underwent functional MRI (fMRI) of the brain. We hypothesized that mothers would show significantly greater cingulate activity during the cries compared to the control sounds. Of 7 subjects scanned, 4 had fMRI data suitable for analysis. When fMRI data were averaged for these 4 subjects, the anterior cingulate and right medial prefrontal cortex were the only brain regions showing statistically increased activity with the cries compared to white noise control sounds (cluster analysis with one-tailed z-map threshold of P < 0.001 and spatial extent threshold of P < 0.05). These results demonstrate the feasibility of using fMRI to study brain activity in mothers listening to infant cries and that the anterior cingulate may be involved in mothers listening to crying babies. We are currently replicating this study in a larger group of mothers. Future work in this area may help (1) unravel the functional neuroanatomy of the parent-infant bond and (2) examine whether markers of this bond, such as maternal brain response to infant crying, can predict maternal style (i.e., child neglect), offspring temperament, or offspring depression or anxiety.
Rate-optimal DSP synthesis by pipeline and minimum unfolding (1994)

This paper presents a rate-optimal scheduling for real-time DSP algorithms. By using pipelining and unfolding techniques, the parallel characteristics of recursive DSP algorithms can be exploited. A novel unfolding technique is developed to unravel all concurrency in the recursive data flow graph. A perfect rate unfolded data flow graph is also introduced, which can cause a fully static rate optimal functional pipeline schedule. Experimental results have shown that the proposed method can always yield rate-optimal designs with a smaller unfolding factor compared to previous studies.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High-Resolution Image Synthesis with Latent Diffusion Models (2021)

By decomposing the image formation process into a sequential application of denoising autoencoders, diffusion models (DMs) achieve state-of-the-art synthesis results on image data and beyond. Additionally, their formulation allows for a guiding mechanism to control the image generation process without retraining. However, since these models typically operate directly in pixel space, optimization of powerful DMs often consumes hundreds of GPU days and inference is expensive due to sequential evaluations. To enable DM training on limited computational resources while retaining their quality and flexibility, we apply them in the latent space of powerful pretrained autoencoders. In contrast to previous work, training diffusion models on such a representation allows for the first time to reach a near-optimal point between complexity reduction and detail preservation, greatly boosting visual fidelity. By introducing cross-attention layers into the model architecture, we turn diffusion models into powerful and flexible generators for general conditioning inputs such as text or bounding boxes and high-resolution synthesis becomes possible in a convolutional manner. Our latent diffusion models (LDMs) achieve a new state of the art for image inpainting and highly competitive performance on various tasks, including unconditional image generation, semantic scene synthesis, and super-resolution, while significantly reducing computational requirements compared to pixel-based DMs. Code is available at https://github.com/CompVis/latent-diffusion .
A procedure for the complete clarification of milk of various species and its suitability for use with colorimetric measurements (1984)

Summary Bovine, caprine, ovine and human milks have been clarified by addition of Triton X-100 and EDTA followed by a short incubation. Generally, addition of 4·2% Triton X–100 and 5·4% EDTA was sufficient and with skim-milk samples no dilution was necessary. With whole milks some dilution and greater amounts of Triton X-100 or longer incubation times or higher temperatures were required. These factors were interrelated to some extent and the optimum conditions will be determined by convenience and any particular requirements of the experiment. The attainment of optically transparent milk samples greatly facilitates colorimetric measurements; as examples we have shown that total protein may be estimated by the biuret reaction, NH 2 groups measured with 2,4,6-trinitrobenzene sulphonic acid and SH groups by reaction with 5, 5′-dithiobis(2-nitrobenzoic acid). Acid phosphatase activity in bovine milk was followed colorimetrically by reaction with p -nitrophenyl phosphate to demonstrate the suitability of the clarification procedure in the measurement of enzymic reactions.

A study of concurrent real-time garbage collectors (2008)

Concurrent garbage collection is highly attractive for real-time systems, because offloading the collection effort from the executing threads allows faster response, allowing for extremely short deadlines at the microseconds level. Concurrent collectors also offer much better scalability over incremental collectors. The main problem with concurrent real-time collectors is their complexity. The first concurrent real-time garbage collector that can support fine synchronization, STOPLESS, has recently been presented by Pizlo et al. In this paper, we propose two additional (and different) algorithms for concurrent real-time garbage collection: CLOVER and CHICKEN. Both collectors obtain reduced complexity over the first collector STOPLESS, but need to trade a benefit for it. We study the algorithmic strengths and weaknesses of CLOVER and CHICKEN and compare them to STOPLESS. Finally, we have implemented all three collectors on the Bartok compiler and runtime for C# and we present measurements to compare their efficiency and responsiveness.
A Feasible One-Step Synthesis of Hierarchical Zeolite Beta with Uniform Nanocrystals via CTAB (2018)

A hierarchical zeolite Beta has been prepared by a feasible one-pot and one-step method, which is suitable for application in industrial production. The synthesis is a simple hydrothermal process with low-cost raw materials, without adding alcohol or adding seeds, and without aging, recrystallization, and other complex steps. The hierarchical zeolite Beta is a uniform nanocrystal (20⁻50 nm) aggregation with high external surface area (300 m²/g) and mesoporous volume (0.50 cm³/g), with the mesoporous structure composed of intercrystal and intracrystal pores. As an acid catalyst in benzylation of naphthalene with benzyl chloride, the hierarchical zeolite Beta has shown high activity in the bulky molecule reaction due to its introduction of mesostructure.

NANOTECHNOLOGY ON ANIMAL PRODUCTION (2010)

La nanotecnologia, entendida como aquella tecnologia en la cual los materiales y las estructuras se encuentran en escalas nanometricas, posee un campo de aplicacion e investigacion crecientes, ya que los materiales a escala pequena adquieren propiedades y caracteristicas distintas que aquellos a escala mayor. Recientemente, ha incrementado la investigacion de los usos de la nanotecnologia en el area de la biologia, especialmente en la administracion de farmacos para seres humanos, y existe la necesidad de aplicar dichos conocimientos en el area zootecnica, particularmente lo que concierne a salud animal, con el objetivo de facilitar y optimizar los procesos de produccion de alimentos de origen animal. Sin embargo, existe poca o nula investigacion al respecto, a pesar que gran parte de la investigacion enfocada a la salud humana se realiza con modelos animales. Esto es de particular interes al considerarse animales destinados a consumo humano, donde deben de tenerse en cuenta factores eticos, ambientales y de seguridad alimentaria. Por lo tanto, el objetivo de esta revision es proporcionar una vision general de la nanotecnologia y sus posibles aplicaciones en las areas de veterinaria y zootecnia, basado en las necesidades actuales, en la exploracion de nuevas areas de investigacion en beneficio de la sociedad.
Biosensor development at the University of Utah (1994)

Describes three biosensors: a silicon retina chip, CHEMFET sensors and an optical immunoassay chip utilizing a planar waveguide. These three examples of sensors give a small flavor of the biosensor work ongoing at the University of Utah. Although there are obvious differences between each of these three sensors in terms of their application areas, the parameters measured, and the technologies used, there are several similarities that are shared by many biosensor developments. These include the move toward smaller device sizes, inexpensive fabrication, large-scale manufacturing methods, and improved reliability in actual applications. The extent to which each of these sensors can meet those real-world requirements will largely determine their eventual commercial viability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Towards evasive maneuvers with quadrotors using dynamic vision sensors (2015)

We present a method to predict collisions with objects thrown at a quadrotor using a pair of dynamic vision sensors (DVS). Due to the micro-second temporal resolution of these sensors and the sparsity of their output, the object's trajectory can be estimated with minimal latency. Unlike standard cameras that send frames at a fixed frame rate, a DVS only transmits pixel-level brightness changes (“events”) at the time they occur. Our method tracks spherical objects on the image plane using probabilistic trackers that are updated with each incoming event. The object's trajectory is estimated using an Extended Kalman Filter with a mixed state space that allows incorporation of both the object's dynamics and the measurement noise in the image plane. Using error-propagation techniques, we predict a collision if the 3σ-ellipsoid along the predicted trajectory intersects with a safety sphere around the quadrotor. We experimentally demonstrate that our method allows initiating evasive maneuvers early enough to avoid collisions.
Statistical analysis on the effects of heavy ion irradiation on 65 nm bulk silicon MOS devices (2019)

Abstract In this paper, the effect of heavy ion irradiation on 65 nm bulk silicon MOS devices is experimentally investigated. Different performance degradation behaviour is observed due to the intrinsic random incident of heavy ions. After irradiation, the threshold voltage ( V th ) shifts negatively and the largest V th shift is 54 mV. The drain induced barrier lowing (DIBL) effect deteriorates and DIBL increases by more than 30 mV V −1 . The variation of maximum transconductance ( G m ) is up to 30%. The off-state leakage current ( I off ) increases by several times, up to one order of magnitude. These performance degradation is attributed to the displacement damage in the active region, interface states at gate oxide interface and trapped charges in shallow trench isolation (STI) induced by micro-dose effect. Moreover, statistical analysis on the geometry dependence is firstly demonstrated. The average value of V th shift, DIBL shift, and I off degradation increase with the decrease of gate width. Finally, the influence of technology downscaling from deep-submicron to nanoscale on the heavy ion irradiation effect is statistically analyzed. Four technology nodes (65 nm, 90 nm, 0.18 μ m and 0.25 μ m) are chosen for comparison. The results indicates that the V th shift and DIBL shift increase with the technology downscaling. The I off degradation is strongly correlated with the trapped charge in STI caused by micro-dose effect. The results are helpful to further understand the single event effects of nanoscale bulk silicon MOS devices and may provide guideline for radiation-hardened design.

Refractive index and attenuation characteristics of SiO_2–Ta_2O_5 optical waveguide film (1983)

The refractive index and optical attenuation of sputtered SiO2–Ta2O5 waveguide film were measured in the 0.633–1.32-μm wavelength region. The waveguide film had a large refractive-index range of 1.46–2.08, which can be adjusted by suitable selection of the composition ratio of the SiO2–Ta2O5 target. Substrate heating, up to 270°C, during the sputtering process was effective for obtaining low attenuation. The waveguide films showed low attenuations, <0.41 dB/cm for the TE0 mode. The best fits of the form λγ to the measured attenuation have γ between 0 and −1, where λ is the wavelength. This wavelength dependence of the attenuation can be interpreted based on mode conversions due to the film surface roughness.
