Concurrent multipath transfer in Fi-Wi access networks (2013)

Fiber-Wireless Access Networks (Fi-Wi) shows a promising future owing to the cost effective, high bandwidth and ubiquity features. Previous studies have addressed network layers to provide high data rates and lower delays to enhance the overall network quality without taking into consideration the end user QoS. In order to provide high QoS, transport layer services needs investigation as they work on end to end principle. Stream control transmission protocol (SCTP) is a new transport layer protocol with novel services that can help Fi-Wi access network to enhance the individual end user QoS. In this work, we investigate the usage of concurrent multi-path transfer (CMT) with stream control transmission protocol (SCTP) for Fi-Wi Access Networks. The use of SCTP in Fi-Wi Access network provides bandwidth aggregation, redundancy and resilience to the network. The simulation results show a significant performance gain in terms of throughput when compared with TCP new Reno, a widely used transport layer protocol.
Long-time-storage mechanism for Tm:YAG in a magnetic field (2003)

We obtained a long-time-storage mechanism for spectral features in thulium ions doped into YAG by applying a magnetic field that splits the electronic ground state. We show experimentally that the storage time can be more than 30 s, which is 3 orders of magnitude longer than that of the metastable state that normally is used for information storage in this material. Level splitting and storage lifetimes for various magnetic field strengths of as much as 5 T were investigated. This storage mechanism will be relevant in the many coherent transient-based signal-processing schemes in which Tm:YAG is being used, and we demonstrate long-time storage in a basic data storage application.
The prevalence of social maladjustment among school-age children (1991)

PL 94-142 mandates that students who are seriously emotionally disturbed be provided with a free and appropriate public education. Embedded in the federal definition of serious emotional disturbance is a clause that excludes socially maladjusted students from the diagnostic category. Although socially maladjusted children may therefore not receive special education services, their presence in the schools may have implications for society and particularly for the educational system. However, there is little data concerning the prevalence of socially maladjusted students in the schools. The purpose of this study was to investigate the prevalence of social maladjustment in two rural/suburban school systems in the southeastern United States. Results of the study indicate that the percentage of students reported as exhibiting characteristics of social maladjustment is sufficiently high to indicate that services beyond special education may be necessary to meet their educational and social needs.
Teleporting an unknown quantum state via dual classical and EPR channels (1993)

An unknown quantum state jOEi can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical EPR correlations. To do so the sender, &quot;Alice,&quot; and the receiver, &quot;Bob,&quot; must prearrange the sharing of an EPRcorrelated pair of particles. Alice makes a joint measurement on her EPR particle and the unknown quantum system, and sends Bob the classical result of this measurement. Knowing this, Bob can convert the state of his EPR particle into an exact replica of the unknown state jOEi which Alice destroyed. Expanded version of manuscript submitted to Phys. Rev. Lett. December 1992 PACS numbers: 03.65.Bz, 42.50.Dv, 89.70.+c (a) Permanent address. The existence of long range correlations between Einstein-Podolsky-Rosen (EPR) [1] pairs of particles raises the question of their use for information transfer. Einstein himself used the word &quot;telepathically&quot; in this context [2]. It is known that instantaneous information transfer is definitely impossib...
Use of Botulinum Neurotoxin in Ophthalmology (2016)

Botulinum neurotoxin (BoNT) is the first biological toxin used in the treatment of ophthalmic diseases and to decrease skin wrinkles as an aesthetic agent. When used appropriately, it weakens the force of muscular contraction and/or inhibits glandular secretion. The most common areas for botulinum toxin treatment are the upper face, including the glabella, forehead, brows, and lateral canthal lines, or crow's feet. By relaxing the muscles causing wrinkles, non-permanent results may be achieved with its use. BoNT has gained widespread use in a variety of ophthalmic diseases. The effect of BoNT is temporary, but the therapeutic benefit is usually maintained even after repeated injections. Treatment is usually well tolerated. Complications and side effects associated with the treatment are rare and temporary. Complications occur due to weakness (chemodenervation) of adjacent muscle groups, immunological mechanisms and injection technique. Current therapeutic indications, doses, complications and contraindications of BoNT use in the following disorders related to ophthalmology were investigated: aesthetic use, strabismus, blepharospasm, hemifacial spasm, eyelid retraction, entropion, lacrimal hypersecretion syndrome, and facial paralysis.
Incomplete bivalent pairing in dihaploids of <i>Brassica napus</i> L (1988)

Twenty five polyhaploid plants (2n = 2x = 19, genome formula AC) of Brassica napus (2n = 4x = 38, AACC) were cytogenetically studied. Seven of these were found among field populations and the rest were derived through anther culture of B. napus cv. Regent. Meiotic behaviour at diakinesis and metaphase I revealed nine bivalents and one univalent in more than 40% of the more than 400 pollen mother cells analyzed. However, when the chromosome number of the polyhaploids was doubled using colchicine, 19 bivalents were observed. These doubled plants (2n = 4x = 38, AACC) also had normal behaviour identical to a regular B. napus at other meiotic stages. Quadrivalent associations were observed when the chromosome numbers were doubled to the octaploid level (2n = 8x = 72, AAAACCCC). It is suggested that A and C are homoeologous genomes. If homologous partners are present, chromosomes would pair within the same genome to form bivalents as occurred in the allotetraploids and to form quadrivalents as occurred in the allooctaploids. However, when a homologous partner is not available, the homoeologous chromosomes would then pair to form bivalents in those polyhaploids.Key words: Brassica napus, polyhaploids, genome relationship, meiotic behaviour, homoeologous pairing.

Platooning control using visible light communications: A feasibility study (2013)

The major benefits of driving vehicles in controlled close formations such as platoons are that of increasing traffic fluidity and reducing air pollution. While Vehicle-toVehicle (V2V) communications is requisite for platooning stability, the existing radio communications technologies (e.g., the IEEE 802.11p) suffer from poor performance in highly dense road scenarios, which are exactly to be created by platooning. This paper studies the applicability of visible light communications (VLC) system for information exchange between the platoon members. A complete VLC model is built enabling precise calculations of Bit-Error-Rate (BER) affected by inter-vehicle distance, background noise, incidence angle and receiver electrical bandwidth. Based on our analytical model, the optical parameters suiting platooning application are defined. Finally, a SIMULINK model is developed to study the performances of a platooning longitudinal and lateral control, where VLC is used for V2V information exchange. Our study demonstrates the feasibility of VLC-based platooning control even in the presence of optical noise at significant levels and up to a certain road curvature.
Global stability of a lid-driven cavity with throughflow: Flow visualization studies (1991)

Flow visualization studies of a lid-driven cavity (LDC) with a small amount of throughflow reveal multiple steady states at low cavity Reynolds numbers. These results show that the well-known LDC flow, which consists of a primary eddy and secondary corner eddies, is only locally stable, becomes globally unstable, and competes with at least three other steady states before being replaced by a time-periodic flow. The small amount of throughflow present in this system seems to have no qualitative effect on the fluid flow characteristics. These observations suggest that multiple stable steady states may also exist in closed LDC’s. Since stability properties of the closed LDC flows are virtually unexplored, we interpret our flow visualization results by first proposing an expected behavior of an idealized (free-slip end walls) LDC and then treating the problem at hand as a perturbation of the ideal case. The results also suggest that there are nonunique and competing sequences of transitions that lead the flow in a LDC from laminar steady state toward turbulence.
A fourth secreted aspartyl proteinase gene (SAP4) and a CARE2 repetitive element are located upstream of the SAP1 gene in Candida albicans (1994)

Candida albicans secreted aspartyl proteinases (Sap), products of the SAP genes, which are presumed to act as virulence factors. In the C. albicans strain WO-1, the ability to secrete Sap1 is regulated with switch phenotype, another putative virulence factor. KpnI restriction fragment length polymorphisms differentiate between several distinct SAP1 alleles in laboratory and clinical strains. Both SAP1 alleles from strain WO-1 along with their 5'- and 3'-flanking regions were cloned and sequenced, as were both alleles from another strain, SS. The 5'-flanking regions were remarkably similar in all four of the sequenced alleles over approximately 1,500 nucleotides. S1 analysis revealed that both alleles of WO-1 are transcribed. Characterization of the one allele from strain WO-1 identified a 284-nucleotide insertion flanked by 8-bp direct repeats that shows homology to the CARE2 repetitive element and that is not present in the other alleles. Characterization of the SAP1 alleles also identified a fourth SAP gene (SAP4) that includes an extended leader sequence. SAP4 is positioned upstream, in tandem to SAP1, in all strains tested and may encode another closely related secreted aspartyl proteinase.
A Smartphone-based Detection of Fall Portents for Construction Workers (2014)

Abstract The construction industry accounts for nearly half of all industry-related fatalities in Taiwan. Identified as the leading cause of such fatalities for several decades, falls also contribute to almost half of work-related fatalities. Given the strenuous nature of construction work, workers are prone to loss of awareness and balance, increasing the safety risk and number of fall accidents. Previous studies have indicated that loss of awareness may be the major cause of occupational injuries or fatalities, and identified the strong correlation between falls and loss of balance. Thus, real-time monitoring of the mental and balance conditions of workers may help identify fall portents, and thus prevent falls from happening. This paper describes a framework for developing a personal safety monitoring system based on a smartphone, which receives external signals wirelessly from motion sensors and brain wave sensors attached to a vest and inside a helmet, and transmit these signals to a monitoring server for further analysis. This paper also presents an experiment with preliminary findings regarding the detection of fall portents, using the internal motion sensors of a smartphone. In the experiment, participants performed a tiling task on a scaffold under four physiological statuses. We identified the fall portents based on the self-awareness of the participants, hazardous actions performed by the participants, and outsider observations by experiment administrators. An accelerometer-based threshold algorithm was tested, and its performance was evaluated against the identified fall portents. The results indicated that the work-related motions had a limited impact on the detection algorithm. The accuracy for the sleepiness, fatigue, normal, and inebriation statuses were 92.3%, 90.4%, 77.3%, and 68.8%, respectively. The algorithm exhibited an overall accuracy of 86%, thus, we conclude that using a smartphone to detect fall portents in a working scenario is feasible, and deserves further investigation.
Complete Genome Structure of the Unicellular Cyanobacterium Synechocystis sp. PCC6803 (1997)

Cyanobacteria are photoautotrophic organisms capable of oxygen-producing photosynthesis similar to that in eukaryotic algae and plants, and because of this, they have been used as model organisms for the study of the mechanism and regulation of oxygen-producing photosynthesis. To understand the entire genetic system in cyanobacteria, the nucleotide sequence of the entire genome of the unicellular cyanobacterium Synechocystis sp. PCC6803 has been determined. The total length of the circular genome is 3,573,470 bp, with a GC content of 47.7%. A total of 3,168 potential protein coding genes were assigned. Of these, 145 (4.6%) were identical to reported genes, and 1,259 (39.6%) and 342 (10.8%) showed similarity to reported and hypothetical genes, respectively. The remaining 1,422 (45.0%) showed no apparent similarity to any genes registered in the databases. Classification of the genes by their biological function and comparison of the gene complement with those of other organisms have revealed a variety of features of the genetic information characteristic of a photoautotrophic organism. The sequence data, as well as other information on the Synechocystis genome, is presented in CyanoBase on WWW [http:/(/)www.kazusa.or.jp/cyano/].
Prostaglandins, Arachidonic Acid, and Inflammation (1980)

The enzymatic oxidation of arachidonic acid has been shown to yield potent pathological agents by two major pathways. Those of the prostaglandin (PG) pathway, particularly PGE2, have been implicated as inflammatory mediators for many years. The discovery and biological activities of thromboxane A2 and prostacyclin as well as a destructive oxygen-centered radical as additional products of this biosynthetic pathway now require these to be considered as potential inflammatory mediators. Like PGE2, their biosynthesis is prevented by nonsteroidal anti-inflammatory agents. More recently, the alternative metabolic route, the lipoxygenase pathway, has been shown to yield a new class of arachidonic acid oxygenation products, called the leukotrienes, which also appear to be important inflammatory mediators. Unlike the prostaglandins, some of which play important roles as biological regulators, the actions of the lipoxygenase products appear to be exclusively of a pathological nature.
Decreased dopamine D<sub>2</sub> receptor availability is associated with reduced frontal metabolism in cocaine abusers (1993)

Decreased dopaminergic function has been postulated to underlie cocaine addiction. To examine the possibility that dysfunction of brain regions subserved by the dopamine system could promote cocaine self-administration, positron emission tomography and a dual-tracer approach was used to examine dopamine D2 receptor availability and regional brain glucose metabolism in cocaine abusers. When compared to normal controls, cocaine abusers showed significant decreases in dopamine D2 receptor availability which persisted 3-4 months after detoxification. Decreases in dopamine D2 receptor availability were associated with decreased metabolism in several regions of the frontal lobes, most markedly orbito-frontal cortex and cingulate gyri. Dopamine dysregulation of these brain areas which are involved in the channeling of drive and affect could lead to loss of control resulting in compulsive drug-taking behavior.
Potential role of the formyl peptide receptor-like 1 (FPRL1) in inflammatory aspects of Alzheimer's disease (2002)

Alzheimer's disease (AD) is a progressive, neurodegenerative disease characterized by the presence of multiple senile plaques in the brain tissue, which are also associated with considerable inflammatory infiltrates. Although the precise mechanisms of the pathogenesis of AD remain to be determined, the overproduction and precipitation of a 42 amino acid form of beta amyloid (Abeta(42)) in plaques have implicated Abeta in neurodegeneration and proinflammatory responses seen in the AD brain. Our recent studies revealed that the activation of formyl peptide receptor-like 1 (FPRL1), a seven-transmembrane, G-protein-coupled receptor, by Abeta(42) may be responsible for accumulation and activation of mononuclear phagocytes (monocytes and microglia). We further found that upon binding FPRL1, Abeta(42) was rapidly internalized into the cytoplasmic compartment in the form of Abeta(42)/FPRL1 complexes. Persistent exposure of FPRL1-expressing cells to Abeta(42) resulted in intracellular retention of Abeta(42)/FPRL1 complexes and the formation of Congo-red-positive fibrils in mononuclear phagocytes. Our observations suggest that FPRL1 may not only mediate the proinflammatory activity of Abeta(42) but also actively participate in Abeta(42) uptake and the resultant fibrillar formation. Therefore, FPRL1 may constitute an additional molecular target for the development of therapeutic agents for AD.
Guide for Roller-Compacted Concrete Pavements (2010)

Roller-compacted concrete (RCC) is an economical, fast-construction candidate for many pavement applications. It has traditionally been used for pavements carrying heavy loads in low-speed areas because of its relatively course surface. However, in recent years its use in commercial areas and for local streets and highways has been increasing. This guide provides owner-agencies, contractors, materials suppliers, and others with a thorough introduction to and updated review of RCC and its many paving applications. Based on current research and best practices, the guide describes RCC and how it works as a paving material, especially compared to concrete pavement, as well as its common used and its benefits and potential limitations compared to other paving materials. It provides detailed overviews of RCC properties and materials, mixture proportioning, structural design issues, and production and construction considerations, plus troubleshooting guidelines and an extensive reference list for more comprehensive information.
Uterine Decidual Response Occurs in Estrogen Receptor-α-Deficient Mice* (1999)

Embryo-uterine interactions leading to the attachment reaction is followed by stromal cell proliferation and differentiation into decidual cells (decidualization) at the sites of blastocyst apposition. In rodents, decidualization is also induced by application of an artificial stimulus (intraluminal oil infusion) in a pseudopregnant uterus, or to one that has been appropriately prepared by exogenous progesterone (P4) and estrogen. The process of decidualization is under the control of these steroids in the presence of blastocysts or deciduogenic stimuli. Although it is well known that estrogen is required for the induction of progesterone receptors in the uterus, the functional importance of estrogen in the process of decidualization is poorly understood. To better understand the role of estrogenic actions in decidualization, we used wild-type and estrogen receptor-alpha knock-out (ERKO) mice for induction of decidualization employing a defined steroid hormonal treatment schedule. Our results demonstrate that P4 alone induces decidualization in ovariectomized wild-type or ERKO mice in response to intraluminal oil infusion in the absence of estrogen. A combined treatment of either estradiol-17beta (E2) or its catecholmetabolite 4-hydroxyestradiol-17beta(4-OH-E2) with P4 does not potentiate the decidual response produced by P4 treatment alone in either ovariectomized wild-type or ERKO mice. The induction of decidual response was associated with up-regulation of decidual cell marker genes, such as progesterone receptor, metallothionein-1, and cyclooxygenase-2. The results suggest that the stromal cell sensitivity to decidualization is critically dependent on P4-regulated events, and estrogenic induction of progesterone receptor via classical nuclear ER-alpha is not critical for this process.
Customization in a UNIX Computing Environment (1993)

This work studies the use of customization in a campus UNIX computing environment where a large computing culture exists, but one that has many diverse interests rather than focusing on a cohesive project. We found there to be a gap between the core system users who use customization facilities and periphery users who show an interest in customization, but are unaware of how to pursue it. These results point to the need for better means for connecting novice users with useful customizations.
Stability of voltage and frequency control in distributed generation based on parallel-connected converters feeding constant power loads (2005)

In this paper stability and dynamic properties of voltage and frequency droop control of power electronic converters are investigated for a distributed generation system. Droop control is utilized to share active and reactive power among the source converters. The voltage and frequency controllers are designed so that stand-alone converter operation feeding constant power loads performs satisfactory. These controllers are adapted to mimic the behaviour of present rotating generators connected directly to the power system, for seam-less transfer between island and grid-connected modes of operation. Small-signal and switch-mode, time-domain simulation results of a three-converter distributed generation system facilitating stand-alone operation verify the operation. Experimental results of a three-converter stand-alone system are also included for verification.
Partial Encryption Schemes for Matching Pursuit (2007)

In this paper a compression integrated partial encryption approach for matching pursuit encoded imagery is discussed with respect to security and compression impact. Reasonable security may be achieved at low computational cost for application scenarios which aim at preventing pleasant viewing conditions for illegitimate users.
Apoptosis: A Product of Programmed and Unprogrammed Cell Death (1993)

Apoptosis is a form of cell death defined by morphological and biochemical characteristics. Although originally described in 1972, it is only very recently that significant interest in the subject has occurred, possibly as a result of the identification of genes that may either positively or negatively regulate the process. With the rapid expansion of knowledge, it has become apparent that there are multiple pathways that induce apoptosis; some of these may represent programmed events but others are clearly unprogrammed. To clarify the terminology used, it is recommended that apoptosis be used as originally defined to refer only to the end product of these pathways. Furthermore, the realization that a cell can die by multiple pathways suggests caution when translating experimental results. Many potential intermediates may be identified but they may represent components of different pathways. Concern for the use of various inhibitors of apoptosis is also presented. Future directions will be aimed at the definitive identification of the signal mechanisms regulating apoptotic cell death.
