Alamouti-Index-Coded PSK Modulation for Priority Ordered Receivers

Noisy index coding problem over a Rayleigh fading channel is studied. The receivers are assumed to be priority ordered with each of them equipped with single antenna and the server with two antennas. To obtain diversity gain along with coding gain, a multiple-input multiple-output (MIMO) scheme which employs space time coding along with index coded PSK modulation, is proposed. For a chosen index code, an arbitrary mapping (of broadcast vectors to PSK signal points) and a 2x1 MIMO system employing Alamouti code, a decision rule for the maximum likelihood (ML) decoding is derived. It is shown that, at very high SNR, the message error performance of the receiver employing ML decoder, depends on the metric called minimum inter-set distance, and for the best coding gain at high SNR, the mapping must maximize the minimum inter-set distance.
Academic and hunter: a portrait of William C. Gartner

It is truly both a privilege and a challenge to present William (Bill) Craig Gartner. A privilege because Bill is one of the top tourism academics of modern times and rightly proud of his academic tourism work. A challenge because some things, using his words, exist above his academic mission and will never “change’’ (Gartner, 2011, p. 88). During autumn every year, this tall professor allows his academic work to suffer, takes his mysterious black dog and disappears into the open space of either North or South Dakota to chase flying ducks and pheasants. During winters, this same hunter disappears off the radar to go ice fishing. In springtime, he dives into the white water and on a raft he has made from tree logs drifts over the rapids, wherever the river may take him. And when he puts his hunting and fishing gear down, he never stops moving in the search for good wine and local cheese. Bill is always on the road, whichever vision – academic or non-academic – he is hunting. Knowing how importantly this other side of Bill complements his academic success, I do not dare to claim to know what his greatest achievements are: his work on tourism development (Gartner, 1996) and place branding (Gartner, 2011) or the size of the fish he caught while in the Artic and the size of the wild boar’s tusks he hunted on the Pannonian plains in Europe.
Cancer Therapy : Preclinical CEBPD Reverses RB / E 2 F 1-Mediated Gene Repression and Participates in HMDB-Induced Apoptosis of Cancer Cells

Purpose: Recent evidence indicates that a tumor suppressor gene CEBPD (CCAAT/enhancer-binding protein delta) is downregulated in many cancers including cervical cancer, which provides a therapeutic potential associated with its reactivation. However, little is known for CEBPD activators and the effect of reactivation of CEBPD transcription upon anticancer drug treatment. In this study, we identified a novel CEBPD activator, 1-(2-hydroxy-5-methylphenyl)-3-phenyl-1,3-propanedione (HMDB). The purpose of this study is to characterize the mechanism of HMDB-induced CEBPD activation and its potential effect in
Optical-Mode Study of Galium Nitrate Based Laser Diodes

This paper focuses on the optical mode analysis of laser diodes to improve light emission. Under the mode analysis, we compare the optical confinement factor (OCF) percentage of the emitting light from the LDs. There are two structures which we analyze: a basic GaN waveguide structure and an InGaN waveguide structure. The second structure has additional InGaN waveguides and is analyzed under two additional design variations: the concentration of Indium and the thickness of the top waveguide layer. The results of this study indicate introducing InGaN waveguide layers correlates with lower order modes (zero and first order) and increase the OCF values. The top InGaN waveguide layer, which has a higher concentration of Indium, appears to increase the OCF. However, the increased thickness of the InGaN layer causes the lower modes’ OFC to decrease. Over all, in the best case, InGaN LD has an OCF of 1.8896%, which is about a 312% improvement compared to that of GaN LD ( OCF=0.4535%).
Performing Configurational Analyses in Management Research : A Fuzzy Set Approach

This article introduces fuzzy set qualitative comparative analysis (fsQCA) as an innovative analytical approach to build causal theories in the area of management studies. Although fsQCA has received considerable attention in many disciplines, such as social and political sciences, its application in management research is still in its infancy. We show how fsQCA as a set-theoretical approach can be used to help improve our understanding of causal relationships between important aspects of management. This is done by providing a framework, which outlines the steps taken in a fuzzy set analysis in order to determine causal conditions, and more importantly configurations of such conditions, and how these contribute to relevant outcomes. In addition, this article illustrates fsQCA by providing an empirical example in the area of management studies, particularly sales growth strategy. The present research contributes to the extant literature by highlighting fsQCA as a novel approach to analyse complex causality, and by discussing options regarding how this approach can be used to complement findings from conventional causal data analysis procedures.
A material and surface morphology independent micro environment “niche” for tissue engineering

In vivo, the cell-cell and cell-ECM interaction contains various niches to regulate organ development. In this study, a micro environment niche, which is independent of material and surface morphology of scaffold, for cell culture is proposed. To define the niche, a micro vibration stage is used to provide precise vibrations on the cell culture device such that the micro shear stress niche between the material and the adhered cells can be estimated. The cultures of bovine endothelial cells (BEC) on three different material culture plates, tissue culture polystyrene (TCPS), poly lactide-co-glycolide (PLGA), and poly lactide acid (PLA), were conducted to illustrate the proposed method. Experimental results demonstrated that the micro shear stresses niche for BEC growth obtained from these three materials are about the same. To further verify the proposed method, the suitable reciprocating frequencies for BEC cultured on a polydimethylsiloxane (PDMS) scaffold was estimated using the conductive shear stress obtained from the original scaffold materials. Proliferation assay further confirmed that the BECs did proliferate well under the calculated reciprocating frequencies. It is hoped that the proposed micro shear stress base niche can be a more cost and time effective solution than the scaffold morphology approaches for the enhancement of cell growth.
Wind waves in shallow microtidal basins and the dynamic equilibrium of tidal flats

[1] Shallow microtidal basins are characterized by extensive areas of tidal flats that lie within specific ranges of elevation. These landforms are inherently flat and their evolution strongly depends on the balance between sedimentary and erosive processes. Here we present a stochastic point model for tidal flat evolution to study the influence of tidal currents and wind waves on tidal flat equilibrium. The model accounts for sediment deposition and sediment resuspension by wind waves and is applied to the Venice lagoon, Italy. Model results show that the equilibrium elevation of tidal flats depends on the relationship between shear stress caused by wind waves and depth. It is found that wind wave shear stresses peak for a specific water depth which is a function of the local wave climate and fetch distance. Above this critical depth, tidal flats are unstable, since an increase in elevation reduces wave height and therefore erosion, preventing the system from recovering equilibrium conditions. The critical depth for equilibrium depends on fetch distance but not on substrate characteristics and, for the Venice lagoon, varies from −1.5 m for unlimited fetch (>3000 m) to −0.6 m for a fetch of 1000 m. The sediment characteristics determine instead the sediment input necessary to maintain the tidal flat in equilibrium at a specific elevation. Sediment inputs for tidal flats composed of fine sand need to be much higher than those required for tidal flats composed of cohesive material. Finally, we show that the spring-neap modulation of the tide is critical for tidal flat equilibrium, with erosive events occurring mostly during spring conditions that equilibrate the sediment deposition during neap tide.

Recurrent patterning in the daily foraging routes of hamadryas baboons (Papio hamadryas): Spatial memory in large‐scale versus small‐scale space

The benefits of spatial memory for foraging animals can be assessed on two distinct spatial scales: small‐scale space (travel within patches) and large‐scale space (travel between patches). While the patches themselves may be distributed at low density, within patches resources are likely densely distributed. We propose, therefore, that spatial memory for recalling the particular locations of previously visited feeding sites will be more advantageous during between‐patch movement, where it may reduce the distances traveled by animals that possess this ability compared to those that must rely on random search. We address this hypothesis by employing descriptive statistics and spectral analyses to characterize the daily foraging routes of a band of wild hamadryas baboons in Filoha, Ethiopia. The baboons slept on two main cliffs—the Filoha cliff and the Wasaro cliff—and daily travel began and ended on a cliff; thus four daily travel routes exist: Filoha–Filoha, Filoha–Wasaro, Wasaro–Wasaro, Wasaro–Filoha. We use newly developed partial sum methods and distribution‐fitting analyses to distinguish periods of area‐restricted search from more extensive movements. The results indicate a single peak in travel activity in the Filoha–Filoha and Wasaro–Filoha routes, three peaks of travel activity in the Filoha–Wasaro routes, and two peaks in the Wasaro–Wasaro routes; and are consistent with on‐the‐ground observations of foraging and ranging behavior of the baboons. In each of the four daily travel routes the “tipping points” identified by the partial sum analyses indicate transitions between travel in small‐ versus large‐scale space. The correspondence between the quantitative analyses and the field observations suggest great utility for using these types of analyses to examine primate travel patterns and especially in distinguishing between movement in small versus large‐scale space. Only the distribution‐fitting analyses are inconsistent with the field observations, which may be due to the scale at which these analyses were conducted. Am. J.

Measurement of Radiation Efficiency of Multiport Antennas With Feeding Network Corrections

Multiport antennas are widely used and often integrated with active components, such as low noise amplifiers, in antenna systems. It is important to verify and evaluate the radiation efficiency of a multiport antenna before being integrated in the system. When the radiation efficiency of a multiport antenna is measured, a multiport feeding network is always needed in order to provide the same antenna excitation as it is during its operation after being integrated in the system. This letter addresses how to measure the radiation efficiency of a multiport antenna excluding the losses in the feeding network used for the measurement, particularly when the impedance match between the antenna and the feeding network is not perfect. A rigorous feeding network correction approach is introduced by using measurement data of the radiation efficiency of the whole antenna with feeding network and the \mbi S-matrices of both the feeding network and the antenna. As an example of this approach, the radiation efficiency of a multiport Eleven antenna has been determined and verified against the simulated results.
hpNFS: A Hierarchical Approach for the Parallel Network File System

Although pNFS (Parallel Network File System) improves the performance of NFS, to optimize the performance of pNFS, we need to deploy high-end network equipment and the data servers need high-end hard disks, which is expensive for many enterprises. As a result, in this work, we presented hpNFS (Hierarchically Parallel Network File System), which is a hierarchical approach of pNFS to decrease the implementation costs and fulfill storage requirements for enterprise. This work is conducted under the ILM (Information Lifecycle Management), where hpNFS is one of the modules of ILM solution. We left a few issues to be resolved by later stage.
Enterotoxigenicity of Vibrio parahaemolyticus with and without genes encoding thermostable direct hemolysin

Vibrio parahaemolyticus produces a thermostable direct hemolysin (TDH) that has been implicated in the pathogenesis of diarrheal disease caused by this organism. However, previous studies attempting to demonstrate the contribution of the hemolysin to virulence have been inconclusive. We investigated this putative virulence factor by using an isogenic TDH-negative (TDH-) strain constructed by specifically inactivating the two copies of the tdh gene encoding TDH. The enterotoxigenicities of the parent strain (AQ3815) and the mutant strain were tested by adding sterile culture supernatants to rabbit ileal tissue mounted in Ussing chambers. The culture filtrate of the parent strain produced a significant increase in short-circuit current (Isc), compared with the change induced by the TDH- mutant. The capacity of the culture filtrate of AQ3815 to increase the Isc was reduced by neutralization with anti-TDH serum, and the return of the cloned tdh gene to the TDH- mutant restored the ability to increase the Isc. These results were corroborated by rabbit ileal loop assays in which AQ3815 caused fluid accumulation but the TDH- mutant did not. No microscopic damage was seen in mucosal tissues exposed to the culture filtrate of either strain. These results indicate that TDH has an enterotoxigenic effect on rabbit small intestine and could be responsible for the watery diarrhea seen with V. parahaemolyticus.
Sch proteins are localized on endoplasmic reticulum membranes and are redistributed after tyrosine kinase receptor activation

The intracellular localization of Shc proteins was analyzed by immunofluorescence and immunoelectron microscopy in normal cells and cells expressing the epidermal growth factor receptor or the EGFR/erbB2 chimera. In unstimulated cells, the immunolabeling was localized in the central perinuclear area of the cell and mostly associated with the cytosolic side of rough endoplasmic reticulum membranes. Upon epidermal growth factor treatment and receptor tyrosine kinase activation, the immunolabeling became peripheral and was found to be associated with the cytosolic surface of the plasma membrane and endocytic structures, such as coated pits and endosomes, and with the peripheral cytosol. Receptor activation in cells expressing phosphorylation-defective mutants of Shc and erbB-2 kinase showed that receptor autophosphorylation, but not Shc phosphorylation, is required for redistribution of Shc proteins. The rough endoplasmic reticulum localization of Shc proteins in unstimulated cells and their massive recruitment to the plasma membrane, endocytic structures, and peripheral cytosol following receptor tyrosine kinase activation could account for multiple putative functions of the adaptor protein.
Perceived Benefits of Group Exercise Among Individuals With Peripheral Neuropathy

Exercise and training programs improve strength, functional balance, and prevent falls in a variety of populations. This article presents the qualitative findings related to the perceived benefits of participants in a randomized controlled trial that compared the effectiveness of group exercise on gait and balance in persons with peripheral neuropathy (PN). Participants with moderately severe PN were randomized into groups that received 10-week classes of Functional Balance Training (FBT) or Tai Chi or education alone. Perceptions of the intervention were overwhelmingly positive regardless of the study group. Perceived benefits reported by participants in the FBT and Tai Chi groups included awareness of how to deal with the effects of neuropathy by implementing balance strategies and a heightened sense of walking to prevent falls. This study offers a guide to design future exercise studies that promote simple balance exercises that can be performed in group settings.
Anisotropic adaptive kernel deconvolution

In this paper, we consider a multidimensional convolution model for which we provide adaptive anisotropic kernel estimators of a signal density $f$ measured with additive error. For this, we generalize Fan's~(1991) estimators to multidimensional setting and use a bandwidth selection device in the spirit of Goldenschluger and Lepski's~(2011) proposal fr density estimation without noise. We consider first the pointwise setting and then, we study the integrated risk. Our estimators depend on an automatically selected random bandwidth. We assume both ordinary and super smooth components for measurement errors, which have known density. We also consider both anisotropic H\"{o}lder and Sobolev classes for $f$. We provide non asymptotic risk bounds and asymptotic rates for the resulting data driven estimator, which is proved to be adaptive. We provide an illustrative simulation study, involving the use of Fast Fourier Transform algorithms. We conclude by a proposal of extension of the method to the case of unknown noise density, when a preliminary pure noise sample is available.
A Krylov-Schur Algorithm for Large Eigenproblems

Sorensen's implicitly restarted Arnoldi algorithm is one of the most successful and flexible methods for finding a few eigenpairs of a large matrix. However, the need to preserve the structure of the Arnoldi decomposition on which the algorithm is based restricts the range of transformations that can be performed on the decomposition. In consequence, it is difficult to deflate converged Ritz vectors from the decomposition. Moreover, the potential forward instability of the implicit QR algorithm can cause unwanted Ritz vectors to persist in the computation. In this paper we introduce a general Krylov decomposition that solves both problems in a natural and efficient manner.
Clinical analysis for the acupuncture treatment in 42 cases of gouty renal damage.

OBJECTIVE To observe the therapeutic effects of acupuncture on gouty renal damage. METHOD 72 cases of gouty renal damage were randomly divided into a treatment group of 42 cases and a control group of 30 cases to observe the therapeutic effects and the changes in 24-hour urinary protein content, blood creatinine, uric acid and urea nitrogen in blood before treatment and one month after treatment. RESULTS The total effective rate in the treatment group reached 95.24%, which was remarkably higher than 63.33% in the control group. After one month of treatment, the indexes were found reduced in both groups, but the reduction rate in the treatment group was obviously superior to that in the control group. CONCLUSION The patients with repeated attacks of gout may have a higher possibility to suffer from renal damage. Therefore, attention should be paid to its early diagnosis and treatment. Acupuncture may exert good therapeutic effects on early gout complicated with renal damage by adjusting the metabolism and improving the renal function.
The choice of controller zeros

The positioning of the controller zeros near the slow process poles though greatly improving the speed of response for a set-point change, can be detrimental to load rejection. This result is used to explain the heuristics used in the Ziegler-Nichols tuning formula for proportional-integral-derivative controllers and in the positioning of controller zeros in pole-placement controllers and phase-lag compensators. <<ETX>>
Downscaling Global Weather Forecast Outputs Using ANN for Flood Prediction

Downscaling global weather prediction model outputs to individual locations or local scales is a common practice for operational weather forecast in order to correct the model outputs at subgrid scales. This paper presents an empirical-statistical downscaling method for precipitation prediction which uses a feed-forward multilayer perceptron (MLP) neural network. The MLP architecture was optimized by considering physical bases that determine the circulation of atmospheric variables. Downscaled precipitation was then used as inputs to the super tank model (runoff model) for flood prediction. The case study was conducted for the Thu Bon River Basin, located in Central Vietnam. Study results showed that the precipitation predicted by MLP outperformed that directly obtained from model outputs or downscaled using multiple linear regression. Consequently, flood forecast based on the downscaled precipitation was very encouraging. It has demonstrated as a robust technology, simple to implement, reliable, and universal application for flood prediction through the combination of downscaling model and super tank model.
Cerebral blood flow response and its association with symptoms during orthostatic hypotension.

INTRODUCTION The preservation of cerebral blood flow with orthostatic hypotension (e.g., following prolonged bed rest or microgravity exposure) is vital for the attenuation of symptoms and the maintenance of consciousness. We tested the hypothesis that decreasing mean arterial pressure (MAP) by > 30% is associated with compromised cerebral autoregulation and orthostatic symptoms during a squat-stand test (SST). METHODS There were 19 subjects who performed an SST. MAP and middle cerebral artery blood flow velocity (CBFV) were recorded continuously. Subjects were divided retrospectively into those who reported: (1) at least one orthostatic symptom (Sx; n=9); or (2) no orthostatic symptoms (NSx; n=10). Cerebral autoregulation was assessed via the calculation of time to nadir and time to recovery for MAP and CBFV and linear regression analysis of the dynamic changes in MAP and CBFV (within 10 s of standing). RESULTS On standing, MAP decreased by 37 +/- 2% (NSx) and 42 +/- 4% (Sx) (p = 0.100). CBFV fell by 6% more in the Sx group than in the NSx group (NSx, -33 +/- 1% vs. Sx, -39 +/- 3%, p = 0.032). Cerebral autoregulation remained intact in both groups as indicated by: (1) a faster time to nadir for CBFV compared with MAP; (2) a faster time to recovery for CBFV compared with MAP; and 3) a poor correlation between CBFV and MAP responses on standing (NSx R2 = 0.43; Sx R2 = 0.60). CONCLUSION Lower cerebral blood flow during severe hypotension may account for the reporting of orthostatic symptoms, despite the maintenance of cerebral autoregulation.
