It can cause interference for medical equipment;· turn off the modem in aircrafts. Take measures against accidental activation;· turn off the modem in the vicinity of gas-filling stations, chemical enterprises, blastingwork places. It can cause interference to technical devices;· at a short range the modem may cause harmful interference to TV and radio receivers.Prevent the modem from dust and moisture.Improper use deprives you of all warranty claims.3

4that is, explaining the differences through a history of gene duplications and losses—isknown as lineage sorting or reconciliation and produces a list of gene duplications andlosses along each edge in the species tree. While reconciliation is a hard computationalproblem, algorithms have been devised for it in a Bayesian framework [2] or using asimple parsimony criterion [10].3 THE NEW NETWORK EVOLUTION MODELAlthough transcriptional regulatory networks produced from bench experiments areavailable for only a few model organisms, other types of data have been used to assistin the comparative study of regulatory mechanisms across organisms [9, 24, 25].For example, gene-expression data [25], sequence data like transcriptional factor bindingsite (TFBS) data [9, 24], and cis-regulatory elements [25] have all been used inthis context. Moreover, a broad range of model organisms have been studied, includingbacteria [4], yeast [9, 25], and fruit fly [24], thus spanning a broad evolutionary range.However, while these studies are promising, they have not to date sufficed to establisha clear model for regulatory networks or their evolution.Our new model remains simple, but can easily be generalized or associated withother models, such as the evolutionary model of TFBSs [16]. In this new model, thenetworks are represented by binary adjacency matrices. The evolutionary operationsare:– Gene duplication: a gene is duplicated with probability p d . After a duplication,edges for the newly generated copy can be assigned as follows:Neutral initialization: Create connections between the new copy and other genesrandomly according to the proportion π 1 of edges in the background networkindependently of the original copy.Inheritance initialization: Connections of the duplicated copy are reported to correlatewith those of the original copy [4, 23, 26]. This observation suggests lettingthe new copy inherit the connections of the original, then lose some ofthem or gain new ones at some fixed rate [6].ΠPreferential attachment: The new copy gets preferentially connected to genes withhigh connectivity [5, 6].– Gene loss: a gene is deleted along with all its connections with probability p l .– Edge gain: an edge between two genes is generated with probability p 01 .– Edge loss: an existing edge is deleted with probability p 10 .The model parameters are thus p d , p l , the proportions of 0s and 1s in the networksPpπ 0 π 1¡, the substitution matrix of 0s and 1s, 00 p 01parametersp 10 p 11plussuitable to the initialization model.4 THE NEW REFINEMENT METHODSWe begin by collecting the regulatory networks to be refined. These networks may havealready been inferred or they can be inferred from gene-expression data at this pointusing any of the standard network inference methods introduced in Sec. 2.1. The genesin these networks are not required to be orthologous across all species, as the duplication/lossmodel allows for gene families of various sizes. Refinement proceeds in the

MG TerminalUser Manual3. Connection and Setting Up3.1. ConnectionBefore feeding the power supply you need to install the SIM card in the modem (the SIM cardmust be enabled). To do this, you need:· to extract the SIM tray by pressing the SIM tray extract button (Fig. 2.4.1);· to install the SIM card into the SIM tray;· to insert the SIM tray with the SIM card into the modem.No strong physical efforts must be applied while installing the SIM card.Connect the GSM antenna to the antenna connector, as well as the commutating cable (RS232).Feed power supply to the modem through the connector RJ11 (Fig. 2.4.2).Note: GSM antenna, data cables and electrical power unit are not included in the complete setconfiguration.After the power supply feeding, registration occurs automatically, which is signaled by the greenindicator frequent flashing. After the registration is completed, the modem jumps to the operatingmode, the green indicator flashes less frequently (Table 2.6.1).3.2. Control, Restarting and Power OffThe modem control is performed by standard AT commands. For additional information andsupport visit the manufacturer’s site – www.radiofid.ru.Modem restarting can be carried out by the following ways:· by the program method through AT commands,· by eight jumpings of the DTR COM port line into passive state (DTR < 3V), duration ofpulses and the pauses between the pulses must lie within the range 100-500 ms,· by temporary power-off.The modem can be powered off using the following ways:· by the program method, using AT commands (escape to the power standby mode);· directly by power-off.After power-off made by means of AT commands, the modem escapes to the power standbymode (minimum power consumption). Escaping from the power standby mode is performed uponthe DTR of the COM port.11
