Journal Article
The researchers who conducted a review of 995 journal articles on mainstreaming reflect on the finding that there has been much more survey research than direct measurement of teacher and student ...performance. The need for empirical research on instruction and learning in inclusive settings is stressed. (DB)
Antiretroviral therapy during the earliest stage of acute HIV infection (Fiebig I) might minimize establishment of a latent HIV reservoir and thereby facilitate viremic control after analytical ...treatment interruption. We show that 8 participants, who initiated treatment during Fiebig I and were treated for a median of 2.8 years, all experienced rapid viral load rebound following analytical treatment interruption, indicating that additional strategies are required to control or eradicate HIV.
1. Three or four hypodermal cells of each sporangium become differentiated as the archesporial cells. The wall of a sporangium consists of three layers exclusive of the epidermis. The tapetum is a ...physiological rather than a morphological structure, the peripheral part being organized from the wall layers and the axial part from the general tissue. 2. The spindle appears bipolar from its first appearance, being dome-shaped in the early stages. No trace of multipolar spindles was observed. The spindles often persist for a considerable time after division is complete. Bodies having the appearance of centrosomes are frequently seen at the poles. 3. The origin of the supernumerary microspores was not absolutely determined. In many cases where their origin was indicated by spindles or otherwise they appeared to arise by the indirect division of one of the tetrad nuclei. 4. The tube nucleus frequently divides by direct division, forming sometimes as many as six or eight nuclei. In conclusion I wish to express my thanks to Dr. W. A. Kellerman and Mr. J. H. Schaffner for valuable assistance and criticism.
In this paper it is established that any jointly controllable, jointly observable, multi-channel, discrete or continuous time linear system with a strongly connected neighbor communication graph can ...be exponentially stabilized with any pre-specified convergence rate using a time-invariant distributed linear control. As an illustration of how this finding can be used to deal with certain distributed tracking problems, a solution is given to a distributed set-point control problem for a continuous-time, multi-channel linear system in which each and every agent with access to the system is able to independently adjust its scalar-valued, controlled output to any desired set-point value. To better understand the constraints on controller design, the distributed control problem is recast as a classical decentralized control problem. Armed with the tools of decentralized control, including the notion of a "fixed spectrum", it is possible to show quite surprisingly that if the only information each agent is allowed to share with its neighbors is its measured output, then distributed stabilization in some cases is impossible. Using well-known decentralized control concepts, lower bounds are derived on the dimensions of the shared sub-states of local controllers which, if satisfied, guarantee that there will be no fixed closed-loop system eigenvalues to contend with. The decentralized control perspective also enables one to assert definitively that without imposing a partitioning constraint, the closed-loop spectrum of any jointly controllable, jointly observable multi-channel linear system with a strongly connected neighbor graph, can be freely assigned with distributed feedback control. The paper then turns to the important and often overlooked design problem of dealing with the effects of transmission delays across a network. It is explained why in the face of finite delays, exponential stabilization at any prescribed convergence rate can still be achieved with distributed control, at least for discrete-time multi-channel linear systems.
Female members of many cephalopod species house a bacterial consortium in the accessory nidamental gland (ANG), part of the reproductive system. These bacteria are deposited into eggs that are then ...laid in the environment where they must develop unprotected from predation, pathogens, and fouling. In this study, we characterized the genome and secondary metabolite production of Leisingera sp. JC1, a member of the roseobacter clade (Rhodobacteraceae) of Alphaproteobacteria isolated from the jelly coat of eggs from the Hawaiian bobtail squid, Euprymna scolopes. Whole genome sequencing and MLSA analysis revealed that Leisingera sp. JC1 falls within a group of roseobacters associated with squid ANGs. Genome and biochemical analyses revealed the potential for and production of a number of secondary metabolites, including siderophores and acyl-homoserine lactones involved with quorum sensing. The complete biosynthetic gene cluster for the pigment indigoidine was detected in the genome and mass spectrometry confirmed the production of this compound. Furthermore, we investigated the production of indigoidine under co-culture conditions with Vibrio fischeri, the light organ symbiont of E. scolopes, and with other vibrios. Finally, both Leisingera sp. JC1 and secondary metabolite extracts of this strain had differential antimicrobial activity against a number of marine vibrios, suggesting that Leisingera sp. JC1 may play a role in host defense against other marine bacteria either in the eggs and/or ANG. These data also suggest that indigoidine may be partially, but not wholly, responsible for the antimicrobial activity of this squid-associated bacterium.
Describes investigation of information flow involving tabulation of information chunks in subject-matter classes and describing direction-of-flow categories. Information chunks were dominated by ...medical-functional information at intake stage, economic at process stage, and service at outcome stage.
