Modulation format

In this paper, we propose an effective AMC using deep learning (DL) for flexible and adaptive OFDM-based optical networks. The proposed DL-based AMC is able to classify four typical modulation schemes such as binary phase-shift keying (BPSK), quadrature PSK (QPSK), 8-PSK, and 16- quadrature amplitude modulation (QAM) in dynamic network conditions.

This thesis develops a flexible customer behavior analysis system, including essential head pose estimation or F-formation modules. This system will be evaluated in an actual retail store. Further, after studying the system, realizing the mentioned problems of the head pose problem, we also propose a process to collect the head pose dataset and multi-task deep neural network model, fusing face detection and head pose estimation to yield face position and head pose at the same time.

The main aims of this study are to: understand the phenomena of isolated mixing regions (IMRs) in Newtonian fluids agitated in mechanically stirred vessels, in particular, the formation of core torus, using experimental studies; investigate the behavior of IMRs structures by manipulating the operating variables such as impeller rotational speed and direction, as well as geometrical variables such as impeller types and baffle location; investigate the temporal chaotic mixing using different speed modulation protocols.

Optical coherent transmission links utilize a fourdimensional (4d) signal space. We review the search for good modulation formats in 4d, as well the properties of these formats under the (subset of all possible) 4d rotations that occur during fiber transmission.

We report here the direct evidence for the formation of alternative DNA structures in a plasmid DNA, termed pTIR10, containing a 0.23-kb pyrimidine/purine-biased (Pyr/Pur) stretch isolated from the rat genome. Long Pyr/Pur sequences are abundant in eukaryotic genomes, and they may modulate the biological activity of genes and genomes via formation of various types of triplex-related structures. The plasmid DNA in sodium acetate buffer (pH 4.35) was deposited on APS-modified mica, and after drying it was imaged with an atomic force microscope in air. ...

The activity of m-calpain, a heterodimeric, Ca 2+ -dependent cysteine protease appears to be modulated by membrane interactions involving oblique-orientated a-helix formation by a segment, GTAMRILGGVI, in the protein’s smaller subunit. Here, graphical and hydrophobic moment-based analyses predicted that this segment may form ana-helix with strong structural resemblance to the influenza virus peptide, HA2, a known oblique-orientateda-helix former.

The benzoacronycine derivative, S23906-1, was character-ized recently as a novel potent antitumor agent through alkylation of theN2 positionof guanines inDNA.We show here that its reactivity towards DNA can be modulated by glutathione (GSH). The formation of covalent adducts between GSH and S23906-1 was evidenced by EI-MS, and the use of different GSH derivatives, amino acids and dipeptides revealed that the cysteine thiol group is absolutely required for complex formation because glutathione disul-fide (GSSG) and other S-blocked derivatives failed to react covalently with S23906-1. ...

Thrombomodulin (TM) slows down the interaction rate between thrombin and plasminogen activator inhibitor 1 (PAI-1). We now show that the 12-fold reduced inhibition rate in the presence ofTM does not result from an altered distribution between PAI-1 cleavage and irreversible com-plex formation. Surface plasmon resonance (SPR) revealed an over 200-fold reduced affinity of TM for thrombin-VR1 tPA as compared to thrombin, demonstrating the importance ofthe VR1 loop in the interaction ofthrombin withbothTMandPAI-1....

Crk belongs to a family of adapter proteins whose structure allows interaction with tyrosine-phosphorylated proteins and is therefore an important modulator of downstream signals, representing a convergence of the actions of numerous stimuli. Recently, it was demonstrated that chole-cystokinin (CCK) induced tyrosine phosphorylation of proteins related to fiber stress formation in rat pancreatic acini.

Microorganisms produce a large number of pharmaco-logically and biotechnologically important peptides by using nonribosomal peptide synthetases (NRPSs). Due to their modular arrangement and their domain organization NRPSs are particularly suitable for engineering recom-binant proteins for the production of novel peptides with interesting properties.

There is still a controversy over the mechanism of promoter DNA strand separation upon open transcription complex (RPo) formation by Escheri-chia coli RNA polymerase: is it a single or a stepwise process controlled by Mg 2+ ions and temperature? To resolve this question, the kinetics of pseudo-first-order oxidation of thymine residues by KMnO4 in the )11…+2 DNA region of RPo at thekPRpromoter was examined under single-hit conditions as a function of temperature (13–37

We have shown previously that isolated heat shock protein 90 (HSP90) and nitric oxide synthase (NOS), once associated in a heterocomplex, become completely resistant to calpain digestion. In this study, it is shown that, in vivo, under conditions of calpain activation, the protection of NOS degradation occurs.

Amyloid-b(Ab) aggregation and amyloid formation are key pathological features of Alzheimer’s disease, and are considered to be two of the major contributing factors to neurodegeneration and dementia. Identification of small molecule inhibitors that are orally available, have low toxicity and high central nervous system bioavailability is one approach to the potential development of a disease-modifying treatment for Alzheimer’s disease.

Protein aggregation can proceed via disordered or ordered mechanisms, with the latter being associated with amyloid fibril formation, which has been linked to a number of debilitating conditions including Alzheimer’s, Parkinson’s and Creutzfeldt-Jakob diseases. Small heat-shock proteins (sHsps), such as aB-crystallin, act as chaperones to prevent protein aggre-gation and are thought to play a key role in the prevention of protein-mis-folding diseases.

Phosphorylation of tau protein modulates both its physiological role and its aggregation into paired helical fragments, as observed in Alzheimer’s diseased neurons. It is of fundamental importance to study paired helical fragment formation and its modulation by phosphorylation. This study focused on the fourth microtubule-binding repeat of tau, encompassing an abnormal phosphorylation site, Ser356.
