Case 1

Dear E ditor,

We w ould like to submit the enclosed manuscript entitled "GDNF Acutely Modulates Neuronal E xcitability and A-type P otassium Channels in Midbrain Dopaminergic Neurons", whi c h we w i s h to be considered for publication in Nature Neuroscience.

GDNF has long been thought to be a potent neurotrophic factor for the survival of midbrain dopaminergic neurons, whi c h are degenerated in P arkinson’s disease. In this paper, we report an unexpected, acute effect of GDNF on A-type potassium channels, leading to a potentiation of neuronal excitability, in the dopaminergic neurons in culture as w ell as in adult brain slices. Further, we show that GDNF regulates the K+ channels through a mechanism that involves activation of MAP kinase. Thus, this study has revealed, for the first time, an acute modulation of ion channels by GDNF. Our findings challenge the classic view of GDNF as a long-term survival factor for midbrain dopaminergic neurons, and suggest that the normal function of GDNF is to regulate neuronal excitability, and consequently dopamine release. These results may also have implications in the treatment of P arkinson’s di s ease.

Due to a direct competition and conflict of interest, w e request that Drs. XXX of Harvard Univ., and YY of Yale Univ. not be considered as reviewers. With thanks for your consideration, I am

Sincerely yours,

Dear E ditor,

We would like to submit the enclosed manuscript entitled "Ca2+-binding protein frequenin mediates GDNF-induced potentiation of Ca2+ channels and transmitter release", which w e wish to be considered for publication in Neuron.

We believe that two aspects of thi s manuscript w ill make it interesting to general readers of Neuron. First, we report that GDNF has a long-term regulatory effect on neurotransmitter release at the neuromuscular synapses. This provides the first physiological evidence for a role of this new family of neurotrophic factors in functional synaptic transmission. Second, we show that the GDNF effect i s mediated by enhancing the expression of the Ca2+-binding protein frequenin. Further, GDNF and frequenin facilitate synapti c transmission by enhancing Ca2+ channel activity, leading to an enhancement of Ca2+ influx. Thus, thi s study has identi f ied, for the first time, a molecular target that mediates the long-term, synaptic action of a neurotrophic factor. Our findings may al s o have general implications in the cell biology of neurotransmitter release.

1. Title and the central theme of the arti c le.

P aper title: "Mobile Agents for Network Management." This study reviews the concepts of mobile agents and distributed network management system. It proposes a mobile agent-based implementation framew ork and creates a prototype system to demonstrate the superior performance of a mobile agent-based network over the conventional client-server architecture in a large net w ork environment.

2. Which subject/theme of the Journal the material fits

3. Why the material is important in its field and w hy the material should be published in [please type in journal title or acronym]?

The necessity of having an effecti v e computer net w ork is rapidly growing alongside the implementation of information technology. Finding an appropriate network management system

has become increasingly important today's distributed envi r onment. How ever, the conventional centralized architecture, whi c h routinely requests the status information of local units by the central server, is not sufficient to manage the grow ing requests. Recently, a new framework that uses mobile

agent technology to assist the distributed management has emerged. The mobile agent reduces net w ork traffi c, distributes management tasks, and improves operational performance. Given today's bandw i d th demand over the Internet, it is important for the [journal title/acronym] readers

to understand thi s technology and its benefits. This study gives a real-life example of how to use mobile agents for distributed network management. It is the first in the literature that reports the anal y si s of network performance based on an operational prototype of mobile agent-based distributed

network. We strongl y believe the contribution of this study warrants its publication in the [journal title/acronym].

Distributed Diffusion-based Non-negative Least-Mean-Square Algorithm Over Adaptive Networks Xiaolong Deng ABSTRACT In wireless sensor networks, distributed estimation over networks has received a lot of attention due to its broad applicability. We formulate and study distributed estimation algorithm based on diffusion protocols to implement cooperation among individual adaptive nodes. In the networks, every node is equipped with local leaning abilities, and they can share their local estimation and information with their neighbors. When the nodes communicate with each other, they keep to peer-to-peer protocols. And due to the inherent physical characteristics of systems under investigation, non-negativity is one of the most interesting constraints that can usually be imposed on the parameters to estimate. In distributed diffusion-based least-mean-square (LMS) algorithm, we add non-negative characteristics of parameters to the algorithm so that we can get a distributed diffusion-base non-negative least-mean-square algorithm over adaptive networks. Index Terms—Adaptive networks, diffusion algorithm, distributed estimation. least mean square algorithms, nonnegative constraints. INTRODUCTION Consider a network of nodes observing temporal data arising from different spatial sources with possibly different statistical profiles. Each node in the network could function as an individual adaptive filter whose aim is to estimate the parameter of interest through local observations [1]–[3]. An adaptive network structure is obtained where the structure as a whole is able to respond in real-time to the temporal and spatial variations in the statistical profile of the data [4]–[6]. Different adaptation or learning rules at the nodes, allied with different cooperation protocols, give rise to adaptive networks of various complexities and potential. Our formulation is useful in several problems involving estimation and event detection from multiple nodes collecting space–time data [7]–[12]. In many real-life phenomena including biological and physiological ones, due to the inherent physical characteristics of systems under investigation, non-negativity is a desired constraint that can be imposed on the parameters to estimate in order to avoid physically absurd and uninterpretable results. Over the last 15 years, a variety of methods have been developed to tackle nonnegative least-square problems (NNLS)[13]. Active set techniques for NNLS use the fact that if the set of variables which activate constraints is known, then the solution of the constrained least-square problem can be obtained by solving an unconstrained one that only includes inactive variables. The active set algorithm of Lawson and Hanson [14] is a batch resolution technique for NNLS problems. It has become a standard among the most frequently used methods. In [15], Bro and De Jong introduced a modification of the latter, called fast NNLS, which takes advantage of the special characteristics of iterative algorithms involving repeated use of non-negativity constraints. Another class of tools is the class of projected gradient

Research on Trigonometric Leveling Freedu School of Geodesy and Geomatics, Wuhan University,Wuhan430079,China E-mail:1111111111@https://www.360docs.net/doc/666482540.html, Abstract —As the total station trigonometric leveling can survey without the restrictions oftopography. So, we can use it to survey the third &fourth order level survey in some special areas.In this article, we propose a new total station measuring method from combining the defect of traditional measurementmethods. The advantages of this method is that it can improve the precision without measuring height of device and prism, and it canreplace the third and fourth level of measurement under certain conditions. This method can greatly improve efficiency and shortenthe project duration in the construction survey . Keywords- trigonometric leveling ;total station ;error analysis I. I NTRODUCTION Engineering construction often relates to height measurement. Thetraditional measurement methods are leveling surveying andtrigonometry trigonometric leveling. Although the two methods have their own characteristics, but there are shortcomings.With the widespread use of the Total Station and using the track rod with the total station method to measure the elevation of the increasingly popular, traditional trigonometric leveling method has shown its limitations.After a long journey, a new trigonometric leveling method has been summed up.This approach combines the advantages of two traditional approaches to further improve the accuracy of the trigonometric leveling and tosurvey faster. This article systematically expounds the principle of traditional trigonometric leveling methods and the new methods, compares their advantages and disadvantages, and analyses the main errors and measurement accuracy in the process of trigonometric leveling. II. P RINCIPLE OF T RADITIONAL T RIGONOMETRIC L EVELING AND THE N EW M ETHOD The basic formula of the traditional trigonometric leveling: tan B A H H D i t α=++- (1) where A H is the elevation of a known point, B H is the elevation of the unknown point, D is the horizontal distance between the two points, αis the vertical angle when observe from point A to point B,i is instrument height, t is the height of the prism. For traditional methods, total station must be set up in the known elevation point. At the same time, you must measure out the height ofboth the instrument and the prism if you want to measure the elevation of the unknown points. If we can measure the elevation of the measured point while set point of total station arbitrarily like leveling surveying, instead of set it on a known elevation point, and do not measure out instrument and prism,speed of measurement will be faster. As shown in the figure 1, assuming that the elevation of the point A is known, the elevation of the point B is unknown, here we measurethe elevation of other points by total station. Figure 1. Diagram for trigonometric leveling Firstly, seen by trigonometric leveling principle: (tan )B A H H D i t α=-+- (2) where i, t is unknown, but one thing is sure that once the instrument set, value of i will remain unchanged.At the same time choose tracking lever as a reflecting prism, assume that the value of t is also fixed. Seen from formula (2), tan B A H i t H D W α+-=-= (3) By formula (3),the value of W will remain unchanged in any station. And while both A H and tan D αare known, it is possible to calculate the value of W . Operation of this new method is as follows: Shown in Figure 2, elevation of point A is known, elevation of point B is unknown, and the instrument is set up at point C between A and B. The instruments sight point A to get the reading 1V . That 1V =1D 1tan α, and calculate the value of W, W = A H +1D 1tan α. At this time related constants such as elevation of station, instrument height and prism height can beof any value, not necessary to set before measuring. And then set elevation of point Cto W , set the instrument height and prism height to 0. Then elevation of point C is known. Finally sight the target point B and measured its elevation, that is 22tan B H W D α=+ (4) Therefore, using the new method, elevation of point B is 1122tan tan B A H H D D αα=-+ (5)
