A two degree of freedom micro-gripper with grasping and rotating functions for optical fibers assembling (2013)

In this paper, a two degree of freedom flexure-based micro-gripper is proposed and applied in the complicated assembling process of optical fibers. The design concept is modeled on the manipulation of human fingers. Therefore, the two tips of micro-gripper, just like human fingers, can easily grasp the optical fiber with a controllable force and precisely rotate it by the rubbing operation. In addition, some sensors installed on the micro-gripper can enhance the operating accuracy. In the developing process, pseudo-rigid-body model method and virtual work principle are employed to conduct theoretical design. Then the obtained theoretical model is validated and optimized by the finite element analysis. Fabrication of the micro-gripper adopts wire electro discharge machining technology and material of aluminum alloy (AL-7075). Experimental studies are carried out on the prototype to further validate the performance of micro-gripper. Experimental results indicate that the developed micro-gripper can well satisfy the requirements of our mission, which also means that it can be widely used in micro-manipulation field.
Multi-modal Conditional Attention Fusion for Dimensional Emotion Prediction (2016)

Continuous dimensional emotion prediction is a challenging task where the fusion of various modalities usually achieves state-of-the-art performance such as early fusion or late fusion. In this paper, we propose a novel multi-modal fusion strategy named conditional attention fusion, which can dynamically pay attention to different modalities at each time step. Long-short term memory recurrent neural networks (LSTM-RNN) is applied as the basic uni-modality model to capture long time dependencies. The weights assigned to different modalities are automatically decided by the current input features and recent history information rather than being fixed at any kinds of situation. Our experimental results on a benchmark dataset AVEC2015 show the effectiveness of our method which outperforms several common fusion strategies for valence prediction.
Argininemia: A Treatable Genetic Cause of Progressive Spastic Diplegia Simulating Cerebral Palsy: Case Reports and Literature Review (1997)

Argininemia, a rare autosomal recessive urea cycle disorder, is caused by a deficiency of arginase, with resulting elevated plasma arginine and ammonia levels. Reports to date have focused little on the neurology of this disorder or the efficacy of treatments. A MEDLINE search revealed 25 previously reported cases, to which we have added two brothers who presented with late onset progressive spastic diplegia. Though their degree of enzyme deficiency was comparable, the severity of their phenotypic abnormalities differed substantially. With dietary therapy, both showed improved cognitive and motor function. Late metabolic crises occurred in both, resulting in death of the less severely affected brother. Based on analysis of our clinical database, we report on the full spectrum of neurologic abnormalities seen in argininemia with particular focus on the accompanying progressive spastic diplegia and its response to treatment; progressive decline in head growth; distinctive neuroradiologic findings; and life-threatening later complications. Current and potential future therapies and long-term outcome are summarized.
The <scp>Bio3D</scp> packages for structural bioinformatics (2020)

Bio3D is a family of R packages for the analysis of biomolecular sequence, structure, and dynamics. Major functionality includes biomolecular database searching and retrieval, sequence and structure conservation analysis, ensemble normal mode analysis, protein structure and correlation network analysis, principal component, and related multivariate analysis methods. Here, we review recent package developments, including a new underlying segregation into separate packages for distinct analysis, and introduce a new method for structure analysis named ensemble difference distance matrix analysis (eDDM). The eDDM approach calculates and compares atomic distance matrices across large sets of homologous atomic structures to help identify the residue wise determinants underlying specific functional processes. An eDDM workflow is detailed along with an example application to a large protein family. As a new member of the Bio3D family, the Bio3D-eddm package supports both experimental and theoretical simulation-generated structures, is integrated with other methods for dissecting sequence-structure-function relationships, and can be used in a highly automated and reproducible manner. Bio3D is distributed as an integrated set of platform independent open source R packages available from: http://thegrantlab.org/bio3d/.
Neutrophil-mediated Pulmonary Vascular Injury: Synergistic Effect of Trace Amounts of Lipopolysaccharide and Neutrophil Stimuli on Vascular Permeability and Neutrophil Sequestration in the Lung (1987)

The pathogenesis of acute lung injury in humans is obscure, but lipopolysaccharide (LPS), complement activation, and neutrophils have been implicated. We investigated in rabbits the interaction of small amounts of intravascularly administered LPS (100 ng) with neutrophil chemotactic factors, the synthetic chemotactic peptide formyl-norleucyl-leucyl-phenylalanine (FNLP), and the biologically relevant chemotactic fragments of C5 (C5f). These neutrophil stimuli produce neutropenia when injected intravascularly in rabbits, reflecting neutrophil adherence to vascular endothelium. When LPS was injected with FNLP, the duration of neutropenia was enhanced. Studies with radiolabeled neutrophils infused in vivo demonstrated prolonged neutrophil sequestration within the lung in rabbits that were given FNLP plus LPS, an effect that was visible for 4 h after injection. Morphometric analysis of tissue sections 4 h after infusion confirmed the presence of greater numbers of neutrophils in the lungs of animals receiving LPS and FNLP. When a combination of LPS and chemotactic factors was infused at both zero and 6 h, we found a marked enhancement of lung vascular permeability at 24 h (as assessed by radiolabeled albumin accumulation), an effect not seen with either LPS or chemotactic factor alone. Ultrastructural studies revealed neutrophil sequestration and alteration in endothelial cells in the animals that received the combination of LPS and chemotactic factors. Neutrophil depletion with nitrogen mustard completely abolished the increased vascular permeability seen in animals that received LPS and chemotactic factors. This study suggests that small amounts of intravascularly administered LPS enhance the sequestration of neutrophils within the lung and increase lung vascular permeability and endothelial injury caused by neutrophils stimulated by intravascularly administered chemotactic factors. This mechanism may be relevant to the production of acute lung injury in human beings.
Role for NF-κB in the Regulation of Ferritin H by Tumor Necrosis Factor-α (1995)

Ferritin is a ubiquitously distributed iron-binding protein that plays a key role in cellular iron homeostasis. It is composed of two subunits, termed H (heavy or heart) and L (light or liver). In fibroblasts and other cells, the cytokine tumor necrosis factor-alpha (TNF) specifically induces synthesis of the ferritin H subunit. Using nuclear run-off assays, we demonstrate that this TNF-dependent increase in ferritin H is mediated by a selective increase in ferritin H transcription. Transfection of murine fibroblasts with chimeric genes containing the 5'-flanking region of murine ferritin H fused to the human growth hormone reporter gene reveals that the cis-acting element that mediates this response is located approximately 4.8 kilobases distal to the start site of transcription. Deletion analyses delimit the TNF-responsive region to a 40-nucleotide sequence located between nucleotides -4776 and -4736, which we term FER-2. Electrophoretic mobility shift assays and site-specific mutations indicate that this region contains two independent elements: one contains a sequence that binds a member of the NF-kappa B family of transcription factors, and a second contains a novel sequence that partially conforms to the NF-kappa B consensus sequence and may bind a different member of the NF-kappa B/Rel transcription factor family. Thus, effects of an inflammatory cytokine on ferritin are mediated by a family of transcription factors responsive to oxidative stress.

Non-resonant bi-stable frequency-increased power scavenger from low-frequency ambient vibration (2009)

This paper reports the design, fabrication, and testing of an inertial micropower scavenger that utilizes the bi-stable motion of a mechanical mass to convert a board range of low-frequency (<30 Hz), and large-deflection (>250 mum) ambient vibrations into high-frequency electrical output energy. The generator incorporates a novel bi-stable mechanical structure to initiate high-frequency mechanical oscillations in an electromagnetic scavenger. This frequency up-conversion technique enhances the electromechanical coupling and increases the generated power. The fabricated device has a volume of 3.7 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> . It generated a peak power of 558 muW and an average power of 39.5 muW at an input acceleration of 1g applied at 10 Hz.
Cultures and intercultural relations (2011)

The previous chapter questioned a common way of viewing culture as relatively bounded and hermetic and the consequences of this for public policy, with the oscillation between self-determination and assimilation. This chapter elaborates the approach outlined in the first chapter, putting to rest the possibility that by rejecting discrete bounded cultures we throw out also the idea of culture as an effect created by people in their interactions with each other. Culture is found in relationships formed by experience rather than being a structured thing that people 'have' or 'belong to'. If we no longer view cultures as blocs we also have to question common ideas about intercultural experiences.
Seasonal Variation in Daily Temperature Ranges (1991)

Abrupt spring and autumnal changes in the daily temperature range, from low winter values to higher nonwinter values, were noted in the Minneapolis-St. Paul temperature record. Since this feature was even more evident in five rural and small town Minnesota stations, it can be accepted as real. The inverse relationship found between surface albedo and the daily temperature range indicated that the reduced winter temperature range is associated with snow cover. A second factor controlling the temperature range is cloud cover. This led to the conclusion that variation in net solar radiation is the primary factor. A strong statistical relationship between daily temperature range and the three variables considered (solar radiation, albedo, and cloud cover) was limited to the spring and fall. In March-April the statistically significant factors were solar radiation and albedo, while in October-November they were solar radiation and cloud cover. For the October-December period albedo was also statistically important.
Secretory phospholipase A2 pathway in various types of lung injury in neonates and infants: a multicentre translational study (2011)

This study, thanks to its multicenter design, will clarify the role(s) of sPLA2 and its pathway in these diseases: sPLA2 might be the crossroad between inflammation and surfactant dysfunction. This may represent a crucial target for new anti-inflammatory therapies but also a novel approach to protect surfactant or spare it, improving alveolar stability, lung mechanics and gas exchange.
Signature recognition by segmentation and regular line detection (2007)

This paper presents a method of identifying handwritten signature by a good algorithm capable of identifying a signature with high accuracy. Here first a signature image is segmented and then data is extracted from individual blocks. After data is collected then accuracy is measured from both numbers of segments along with regular line matching coefficient. A mathematical formula is used to perform the accuracy measurement. A test signature is compared with a standard signature that is in the database. As the level of accuracy is determined from both number of segments and similarity of lines in these segments, reliability of this method is very high. It has the capability to identify even a skilled forgery.

Stevens–Johnson syndrome with sulfasalazine treatment: Report of two cases (2011)

We report two cases of Stevens-Johnson syndrome (SJS) associated with the use of sulfasalazine in two ulcerative colitis patients previously tolerant to mesalamine. SJS and toxic epidermal necrolysis (TEN) are very rare adverse cutaneous reactions that can be associated with the use of sulfasalazine. The most severe cases can result in death, and for the others, permanent skin, mucosal or ocular sequelae, which can impair the quality of life in our young IBD patients. Clinicians and patients need to be aware of the signs and symptoms that often precede the appearance of the mucocutaneous lesions in a SJS or TEN, such as fever, influenza-like symptoms, sore throat or burning eyes. For patients with SJS or TEN, immediate withdrawal of the offending medication should be done when blisters or erosions appear in the course of a drug eruption, as this may improve the prognosis.
Protection Over Asymmetric Channels, S-MATE: Secure Multipath Adaptive Traffic Engineering (2010)

Several approaches have been proposed to the problem of provisioning traffic engineering between core network nodes in Internet Service Provider (ISP) networks. Such approaches aim to minimize network delay, increase capacity, and enhance security services between two core (relay) network nodes, an ingress node and an egress node. MATE (Multipath Adaptive Traffic Engineering) has been proposed for multipath adaptive traffic engineering between an ingress node (source) and an egress node (destination) to distribute the network flow among multiple disjoint paths. Its novel idea is to avoid network congestion and attacks that might exist in edge and node disjoint paths between two core network nodes. This paper proposes protection schemes over asymmetric channels. Precisely, the paper aims to develop an adaptive, robust, and reliable traffic engineering scheme to improve performance and reliability of communication networks. This scheme will also provision Quality of Server (QoS) and protection of traffic engineering to maximize network efficiency. Specifically, S-MATE (secure MATE) is proposed to protect the network traffic between two core nodes (routers, switches, etc.) in a cloud network. S-MATE secures against a single link attack/failure by adding redundancy in one of the operational redundant paths between the sender and receiver nodes. It is also extended to secure against multiple attacked links. The proposed scheme can be applied to secure core networks such as optical and IP networks.
Hollow fiber microfiltration membranes from poly(ether ether ketone) (PEEK) (1999)

A procedure for obtaining high performance large internal diameter (ID; >1 mm) hollow fiber microfiltration membranes from poly(ether ether ketone) (PEEK) is presented. A simple mixture of isomers of diphenylphthalate is a good solvent for employing the thermal-phase inversion process to obtain PEEK membranes. Obtaining large ID hollow fibers with substantial transmembrane flux requires sufficient melt strength during spinning to prevent excessive draw of the extruding fiber. The use of a second leachable polymer to the blend satisfies the conditions, and polysulphone (PS) is found to provide superior membranes relative to either poly(etherimide) (PEI) or poly(ether sulphone) (PES) as a second polymer. PEEK membranes obtained by this process yield better chemical resistance to a concentrated warm surfactant/oil solution. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 72: 175–181, 1999
Robust real-time PPG-based heart rate monitoring (2015)

Many existing methods for tracking heart rate (HR) from pho-toplethysmographic (PPG) signals can be found in the literature, but they are tested only in static scenarios and fail when motion artifacts are strong. Recently, an algorithm called TROIKA was proposed for robust HR tracking, but the computational complexity of that algorithm is very high which makes it difficult to implement in small embedded devices, such as wrist-wearable HR monitors. In this article we present a new, fast family of methods robust against very strong motion artifacts using spectral subtraction or nonnegative matrix factorization (NMF) for signal enhancement and MA removal and online Viterbi decoding or particle filtering for HR tracking. On our test data set we obtain an average error of 1.3%.
FGF-1: From Biology Through Engineering to Potential Medical Applications (2008)

Human fibroblast growth factor 1 (FGF-1) is one of the best characterized members of the FGF superfamily. FGF-1 is a powerful mitogen exhibiting strong action on numerous different cell types. It plays a role in various stages of development and morphogenesis, as well as in angiogenesis and wound healing processes. Engineering of FGFs can bring many advantages. Design and construction of different mutants can contribute to a better understanding of the mechanism of action of protein growth factors. Moreover, application of FGFs as recombinant polypeptides in the treatment of wound and fracture healing, cardiovascular diseases and neurodegenerative diseases seems to be a rational medical approach. However, low thermal stability and high sensitivity to proteases limit the potential pharmaceutical use of wild-type FGFs. Thus, advanced protein design techniques and recombinant protein production can help to obtain new variants of FGFs with radically increased thermodynamic stability, prolonged half-life and improved proteolytic resistance. Such studies can provide a good starting point to convert short-lived and/or sensitive growth factors to effective therapeutic proteins.
Studies in polymerization - XV. The photosensitized initiation of vinyl polymerization by manganese carbonyl (1965)

Abstract It has been found that a system consisting of manganese carbonyl and a low concentration of carbon tetrachloride can act as an efficient photoinitiator of vinyl polymerization. This paper describes a kinetic study of the mechanism of photoinitiation at λ = 4358 Å, in which methyl methacrylate was the monomer. Trichloromethyl radicals are shown to be the initiating species. The main observations are consistent with a reaction scheme in which a primary product F of the photolysis of the carbonyl forms an adduct with carbon tetrachloride. This adduct may either dissociate into trichloromethyl radicals or be destroyed by reaction with F. Suggestions are made as to the chemical nature of F. Other mechanisms are considered which explain certain of the kinetic features observed. The quantum yield of photoinitiation is a function of [CCl4]/Iabs and rises monotonically with a limit of unity.

A 16-channel spatial-division multiplexed transceiver is demonstrated using a multicore fiber coupled to a dense array of co-integrated 56Gb/s GeSi electro-absorption modulators and photodetectors, realizing 896Gb/s aggregate bi-directional bandwidth in 1.47mm2 silicon footprint.
Quanto pior, melhor: Estudo da utilização da análise por envoltória de dados em modelos de análise de inadimplência/insolvência de empresas (2013)

This paper aims to develop an insolvency/failure analysis model allying accounting information with Data Envelopment Analysis (DEA). The research was conducted in phases: initially previous studies were examined; then samples were obtained from different databases containing financial information of distressed and healthy companies; and, finally a methodology for application of DEA to failure/insolvency analysis was proposed. The results were comparable to those obtained from logistic regression models and neural network models, without, however, a clear indication of the superiority of any procedure.
