A Survey of Wearable Biometric Recognition Systems (2016)

The growing popularity of wearable devices is leading to new ways to interact with the environment, with other smart devices, and with other people. Wearables equipped with an array of sensors are able to capture the owner’s physiological and behavioural traits, thus are well suited for biometric authentication to control other devices or access digital services. However, wearable biometrics have substantial differences from traditional biometrics for computer systems, such as fingerprints, eye features, or voice. In this article, we discuss these differences and analyse how researchers are approaching the wearable biometrics field. We review and provide a categorization of wearable sensors useful for capturing biometric signals. We analyse the computational cost of the different signal processing techniques, an important practical factor in constrained devices such as wearables. Finally, we review and classify the most recent proposals in the field of wearable biometrics in terms of the structure of the biometric system proposed, their experimental setup, and their results. We also present a critique of experimental issues such as evaluation and feasibility aspects, and offer some final thoughts on research directions that need attention in future work.
Mouse VAP33 is associated with the endoplasmic reticulum and microtubules (2000)

VAMP/synaptobrevin is a synaptic vesicle protein that is essential for neurotransmitter release. Intracellular injection of antisera against the Aplysia californica VAMP/synaptobrevin-binding protein ApVAP33 inhibited evoked excitatory postsynaptic potentials (EPSPs) in cultured cells, suggesting that this association may regulate the function of VAMP/synaptobrevin. We have identified and characterized a mouse homologue of ApVAP33, mVAP33. The overall domain structure of the proteins is conserved, and they have similar biochemical properties. mVAP33 mRNA is detectable in all mouse tissues examined, in contrast to the more restricted expression seen in A. californica. We analyzed the cellular distribution of mVAP33 protein in brain slices and cultured cortical cells by light and electron microscopy. Although present at higher levels in neurons, immunoreactivity was detected throughout both neurons and glia in a reticular pattern similar to that of endoplasmic reticulum-resident proteins. mVAP33 does not colocalize with VAMP/synaptobrevin at synaptic structures, but expression overlaps with lower levels of VAMP/synaptobrevin in the soma. Ultrastructural analysis revealed mVAP33 associated with microtubules and intracellular vesicles of heterogeneous size. In primary neuronal cultures, large aggregates of mVAP33 are also detected in short filamentous structures, which are occasionally associated with intracellular membranes. There is no evidence for accumulation of mVAP33 on synaptic vesicles or at the plasma membrane. These data suggest that mVAP33 is an endoplasmic-reticulum-resident protein that associates with components of the cytoskeleton. Any functional interaction between mVAP33 and VAMP/synaptobrevin, therefore, most likely involves the delivery of components to synaptic terminals rather than a direct participation in synaptic vesicle exocytosis.

Interleukin 9 alterations linked to alzheimer disease in african americans (2019)

Baseline and AD-associated IL-9 differences between African Americans and Caucasians point to distinct molecular phenotypes for AD according to ancestry. Genetic and nongenetic factors need to be considered in future AD research involving unique populations. ANN NEUROL 2019;86:407-418.
Nexus: Bringing Efficient and Scalable Training to Deep Learning Frameworks (2017)

Demand is mounting in the industry for scalable GPU-based deep learning systems. Unfortunately, existing training applications built atop popular deep learning frameworks, including Caffe, Theano, and Torch, etc, are incapable of conducting distributed GPU training over large-scale clusters. To remedy such a situation, this paper presents Nexus, a platform that allows existing deep learning frameworks to easily scale out to multiple machines without sacrificing model accuracy. Nexus leverages recently proposed distributed parameter management architecture to orchestrate distributed training by a large number of learners spread across the cluster. Through characterizing the run-time behavior of existing single-node based applications, Nexus is equipped with a suite of optimization schemes, including hierarchical and hybrid parameter aggregation, enhanced network and computation layer, and quality-guided communication adjustment, etc, to strengthen the communication channels and resource utilization. Empirical evaluations with a diverse set of deep learning applications demonstrate that Nexus is easy to integrate and can deliver efficient distributed training services to major deep learning frameworks. In addition, Nexus's optimization schemes are highly effective to shorten the training time with targeted accuracy bounds.
Flexible twist polarizer based on ultrathin multi‐layered polymer‐carbon nanotubes composite films (2017)

Abstract We present an ultrathin and flexible microwave broadband polarization transformer concept based on oriented carbon nanotubes dispersed in a polycarbonate matrix. Stacking anisotropic composite films with a controlled angle mismatch between successive layers produces a twist polarizer able to change the orientation of the electric field over broad frequency range in the microwave domain. The smart organization confers to the multilayer a high efficiency measured as a degree of twist, which reaches 75.1% at GHz frequencies for a 420 μm thick seven‐layer stack.
Isolation and Characterization of Organosolv Lignin under Alkaline Condition from Wheat Straw (1997)

Abstract Delignification of wheat straw with aqueous ethanol in the presence of alkaline catalyst has been studied. The use of 60% (v/v) ethanol under alkaline condition (0.5 N NaOH) resulted in increased rate of delignification by 7.1% as compared with the treatment of wheat straw in 0.5 N NaOH medium without ethanol. The chemical composition of the lignin fraction isolated by two steps of precipitation are reported. The characteristics of the lignin were further investigated by gel permeation chromatography (GPC), infrared (IR) and 13C-nuclear magnetic resonance (NMR) spectroscopy.
A Petri-net-based approach to real-time program analysis (1993)

We propose to extend existing Petri-net-based tools for concurrency analysis to real-time analysis. The goal is to create a fully automated system, which starts from code in a higher level language for real-time programming, and answers programmers' queries about timing properties of the code. The key difficulty with all reachability-based approaches is that the state space quickly becomes intractably large. To circumvent this state explosion problem, we propose using a combination of several heuristics for model reduction and state space reduction that have been effective for untimed concurrency analysis. >
Radical Scavenging Activity of Tea Catechins and Their Related Compounds (1999)

(-)-Epigallocatechin gallate was found to be the most effective scavenger among tea catechins for the superoxide anion, hydroxyl radical, and 1,1-diphenyl-3-picrylhydrazyl radical. Examination of the scavenging effects of tea catechins and their glucosides on superoxide anion showed that the presence of at least an ortho-dihydroxyl group in the B ring and a galloyl moiety at the 3 position was important in maintaining the effectiveness of the radical scavenging ability. Stoichiometric factors of tea catechins were estimated to be 2 for (+)-catechin and (-)-epicatechin, 5 for (-)-epigallocatechin, 7 for (-)-epicatechin gallate, and 10 for (-)-epigallocatechin gallate.
Vertebroplasty and Kyphoplasty (2002)

Vertebral fractures are a major health care problem in Western countries. Pain and deformity are the major problems related to these fractures, with an enormous impact on the quality of life. Surgery is indicated in patients with concurrent spinal instability or neurologic deficit. The cornerstone of management for vertebral body fractures without neurological impairment is medical therapy, which include analgesics, bed rest, orthoses and rehabilitation. In the majority of patients such treatment modalities are effective. However, conservative management measures are not indicated for every type of fracture. Two different percutaneous minimally invasive vertebral augmentation methods for cement application into the vertebral body in the management of symptomatic fractures without neurological impairment have been developed, namely vertebroplasty and kyphoplasty. Aim of this paper is to give an overview of the state of the art about vertebroplasty and kyphoplasty, discussing the indications, techniques, results and pitfalls.

Adeno-associated virus capsid antigen presentation is dependent on endosomal escape (2020)

Adeno-associated virus (AAV) vectors are attractive for gene delivery-based therapeutics, but data from recent clinical trials have indicated that AAV capsids induce a cytotoxic T lymphocyte (CTL) response that eliminates transduced cells. In this study, we used traditional pharmacological agents and AAV mutants to elucidate the pathway of capsid cross-presentation in AAV-permissive cells. Endosomal acidification inhibitors blocked AAV2 antigen presentation by over 90%, while proteasome inhibitors completely abrogated antigen presentation. Using mutant viruses that are defective for nuclear entry, we observed a 90% decrease in capsid antigen presentation. Different antigen presentation efficiencies were achieved by selectively mutating virion nuclear localization signals. Low antigen presentation was demonstrated with basic region 1 (BR1) mutants, despite relatively high transduction efficiency, whereas there was no difference in antigen presentation between BR2 and BR3 mutants defective for transduction, as compared with wild-type AAV2. These results suggest that effective AAV2 capsid antigen presentation is dependent on AAV virion escape from the endosome/lysosome for antigen degradation by proteasomes, but is independent of nuclear uncoating. These results should facilitate the design of effective strategies to evade capsid-specific CTL-mediated elimination of AAV-transduced target cells in future clinical trials.
Linker Chemistry Determines Secondary Structure of p53<sub>14−29</sub>in Peptide Amphiphile Micelles (2010)

Biofunctional micelles formed via self-assembly of synthetic peptide-lipid conjugates are a class of promising biomaterials with applications in drug delivery and tissue engineering. The micelle building block, termed peptide amphiphile, consists of a lipid-like chain covalently linked through a spacer to a peptide headgroup. Self-assembly results in formation of a hydrophobic core surrounded by a dense shell with multiple, functional peptides. We report here on the effect that different linkers between a palmitic tail and a bioactive peptide (p5314-29) have on headgroup secondary structure. Peptide p5314-29 may act as an inhibitor of the interaction between tumor suppressor p53 and human double minute-2 (hDM2) proteins by binding hDM2 in a partially helical form, leading to the release of p53 and the induction of apoptosis in certain tumors. Circular dichroism and fluorescence spectroscopy data revealed that the extent and type of secondary structure of p5314-29 are controlled through size and hydrogen bond potential of the linker. In addition, the structure of the self-assembled micelles was influenced through linker-dependent altered headgroup interactions. This study provides insight into the mechanisms through which headgroup structuring occurs on peptide amphiphile micelles, with implications on the bioactivity, stability, and morphology of the self-assembled entities.
Rhythm of daily living and detection of atypical days for elderly people living alone as determined with a monitoring system (2006)

We have developed a system for monitoring the health of elderly people living at home. Infrared and other sensor outputs are collected using a monitoring program installed on a personal computer (PC) in the home at a sampling rate of 1 Hz. Once each day, the data are transferred to a server through the Internet using a cable television (TV) connection. An elderly subject was monitored for a 12-day baseline period and completed a daily questionnaire about her activities. This enabled us to identify the rhythm of daily living (sleeping, 23:00-04:59; getting up/breakfast, 05:00-08:59; indoor activities/going out, 09:00-16:59; and dinner/going to bed, 17:00-22:59) and the average outputs from the sensors in the rooms. The subject was then monitored for a further six months. By identifying sensor output counts outside the limits of mean +/- 3SD, we were able to detect atypical days. During the six-month monitoring period, 29 atypical days were detected. We suggest that the monitoring system may be effective in tele-rehabilitation.
Inflammatory large bowel disease in immunodeficient mice naturally infected with Helicobacter hepaticus. (1996)

Large bowel disease detected clinically by rectal prolapse was studied in 64 immunodeficient mice (37 athymic NCr-nu/nu, 12 BALB/c AnNCr-nu/nu, 9 C57BL/6NCr-nu/nu, and 6 C.B17/Icr-scid/NCr) naturally infected with Helicobacter hepaticus. Rectal prolapse was found in approximately 5% of immunodeficient mice maintained in a research facility over a period of 3.5 years. All mice had various degrees of chronic proliferative typhlitis, colitis, and proctitis, usually without concomitant hepatitis. Some mice had severe proliferative proctitis with cystic hyperplasia. Histologic study of the large bowel of 48 athymic NCr-nu/nu mice without H. hepaticus infection and housed in another clean facility revealed only 12% of the mice with minimal-to-mild large bowel inflammation. Helicobacter hepaticus infection is associated with large bowel disease in immunodeficient mice but is not seen in H. hepaticus-infected immunocompetent mice. This new pathogenic bacterial infection should be considered as another potential cause or co-factor for rectal prolapse and large bowel disease in mice.
Assessing Acute Ventricular Volume Changes by Intracardiac Impedance in a Chronic Heart Failure Animal Model (2009)

The strong correlation with SV allows the application of intracardiac impedance measurements for an implant-based continuous monitoring of cardiac function. Impedance may also be used for hemodynamic optimization of cardiac resynchronization therapy.
P‐43: Evaluation of Moving‐Picture Quality on 42‐in. PDP (1998)

Abstract The effect of new signal processing and driving methods introduced to 42‐inch HDTV DC PDP to improve moving picture quality is evaluated by both computer simulation and subjective evaluation of the moving pictures. The results show that our techniques sufficiently improve picture quality for practical use in the HDTV PDP receiver.
Simultaneous Cre catalyzed recombination of two alleles to restore neomycin sensitivity and facilitate homozygous mutations (1999)

Cells homozygous for neo-expressing mutations can be derived by culturing heterozygotes with elevated G418. We demonstrate that this strategy is significantly less efficient if hyg is substituted for neo. Therefore, to introduce additional mutations Cre recombinase was used to remove floxed neo from both alleles of homozygotes at two different loci. The rate-determining step in Cre excision appeared independent of substrate copy number. Incorporating cytosine deaminase and Herpes simplex virus thymidine kinase allowed negative selection for both targeting and Cre excision. The resulting G418-sensitive homozygous mutants should allow mutagenesis at additional loci and avoid untoward effects of retained selection markers.

<title>Inter-view wavelet compression of light fields with disparity-compensated lifting</title> (2003)

We propose a novel approach that uses <i>disparity-compensated lifting</i> for wavelet compression of light fields. Disparity compensation is incorporated into the lifting structure for the transform across the views to solve the irreversibility limitation in previous wavelet coding schemes. With this approach, we obtain the benefits of wavelet coding, such as scalability in all dimensions, as well as superior compression performance. For light fields of an object, shape adaptation is adopted to improve the compression efficiency and visual quality of reconstructed images. In this work we extend the scheme to handle light fields with arbitrary camera arrangements. A view-sequencing algorithm is developed to encode the images. Experimental results show that the proposed scheme outperforms existing light field compression techniques in terms of compression efficiency and visual quality of the reconstructed views.
From inflammation to depression - St Johns wort as a therapeutic approach (2013)

An increasing number of clinical and preclinical data shows that inflammatory processes may be involved in the etiology of depression [1, 2]. At least in some depressed patients inflammation markers are enhanced. An IFN-α-induced rise of TNF-α and IL-6 may induce depressive symptoms [3]. Psychic stress is not only a trigger of depressive symptoms, but also of a lower antioxidative capacity, similar to that in inflammatory diseases.
Xerostomia: A Prevalent Condition in the Elderly (1999)

Although xerostomia is associated with aging, studies have determined that salivary gland function is well preserved in the healthy geriatric population. Therefore, dry mouth is probably not a condition of aging, but most likely one of systemic or extrinsic origin. Saliva seems to undergo chemical changes with aging. As the amount of ptyalin decreases and mucin increases, saliva can become thick and viscous and present problems for the elderly. One of the most prevalent causes of xerostomia is medication. Anticholinergics, such as psychotropic agents and antihistamines, and diuretics can dry the oral mucosa. Chronic mouth breathing, radiation therapy, dehydration, and autoimmune diseases, such as Sjögren's, can also diminish salivation, as can systemic illness such as diabetes mellitus, nephritis, and thyroid dysfunction. Xerostomia can lead to dysgeusia, glossodynia, sialadenitis, cracking and fissuring of the oral mucosa, and halitosis. Oral dryness can affect denture retention, mastication, and swallowing. Dry mouth symptom can be treated with hydration and sialagogues or with artificial saliva substitutes. Because patients are at risk for dental caries, they should be referred to a dentist for preventive care. In patients with Sjögren's syndrome and in those who have undergone radiation therapy, pilocarpine has been used recently with good results.
A New Approach to the Analysis of Multidimensional Neuronal Activity: Markov Random Fields (1997)

How can information hidden in a spatial configuration of neuronal activity be addressed? The Markov Random Field method for the analysis of the spatial component of a multidimensional neuronal process is introduced and after simulations is applied to experimental data on rat at olivocerebellar activity. Using this method it was determined, for the first time, that the activity demonstrates dynamic coupling and may have different fine spatial substructures. The results obtained support the view that the inferior olive serves as a movement organizing centre that controls motor activity by means of spatially as well as temporally organized patterns of coherent activity.

Injury Profile SIMulator, a Qualitative Aggregative Modelling Framework to Predict Crop Injury Profile as a Function of Cropping Practices, and the Abiotic and Biotic Environment. I. Conceptual Bases (2013)

The limitation of damage caused by pests (plant pathogens, weeds, and animal pests) in any agricultural crop requires integrated management strategies. Although significant efforts have been made to i) develop, and to a lesser extent ii) combine genetic, biological, cultural, physical and chemical control methods in Integrated Pest Management (IPM) strategies (vertical integration), there is a need for tools to help manage Injury Profiles (horizontal integration). Farmers design cropping systems according to their goals, knowledge, cognition and perception of socio-economic and technological drivers as well as their physical, biological, and chemical environment. In return, a given cropping system, in a given production situation will exhibit a unique injury profile, defined as a dynamic vector of the main injuries affecting the crop. This simple description of agroecosystems has been used to develop IPSIM (Injury Profile SIMulator), a modelling framework to predict injury profiles as a function of cropping practices, abiotic and biotic environment. Due to the tremendous complexity of agroecosystems, a simple holistic aggregative approach was chosen instead of attempting to couple detailed models. This paper describes the conceptual bases of IPSIM, an aggregative hierarchical framework and a method to help specify IPSIM for a given crop. A companion paper presents a proof of concept of the proposed approach for a single disease of a major crop (eyespot on wheat). In the future, IPSIM could be used as a tool to help design ex-ante IPM strategies at the field scale if coupled with a damage sub-model, and a multicriteria sub-model that assesses the social, environmental, and economic performances of simulated agroecosystems. In addition, IPSIM could also be used to help make diagnoses on commercial fields. It is important to point out that the presented concepts are not crop- or pest-specific and that IPSIM can be used on any crop.
Qualitative and quantitative assessment of aerospace structures by pulsed thermography (2007)

Abstract Pulsed thermography (PT) is an NDT&E technique allowing the remote examination of materials and systems. PT is particularly interesting for the inspection of aerospace structures since it can be used to perform safe inspection of large structures in a fast manner and without having to remove the components from the aircraft. Pulsed thermographic data however, is contaminated by noise of many forms. Fortunately, numerous signal processing techniques are available to perform qualitative and quantitative data analysis of data. In this paper, we present three processing techniques that have shown very promising results. We provide the theoretical background and experimental details as well as some representative results that highlight the pros and cons of each technique. As it will be pointed out, an interesting approach is the combination of existing processing techniques in order to use the most attractive features from each technique while reducing the non-desirable characteristics.
