Event-Driven Optimal Feedback Control for Multiantenna Beamforming (2010)

Transmit beamforming is a simple multiantenna technique for increasing throughput and the transmission range of a wireless communication system. The required feedback of channel state information (CSI) can potentially result in excessive overhead especially for high mobility or many antennas. This work concerns efficient feedback for transmit beamforming and establishes a new approach of controlling feedback for maximizing throughput under a constraint on the average feedback rate. The feedback controller using a stationary policy turns CSI feedback on/off according to the system state that comprises the channel state and transmit beamformer. Assuming channel isotropy and Markovity, the controller's state reduces to two scalars. This allows the optimal control policy to be efficiently computed using dynamic programming. Consider the unquantized feedback channel free of error, where each feedback instant pays a fixed price. The corresponding optimal feedback control policy is proved to be of the threshold type. This result holds regardless of whether the controller's state space is discretized or continuous. Under the threshold-type policy, feedback is performed whenever a state variable indicating the accuracy of transmit CSI is below a threshold, which varies with channel power. The practical quantized feedback channel is also considered. The optimal policy for quantized feedback is proved to be also of the threshold type. The effect of CSI quantization is shown to be equivalent to an increment on the feedback price. Moreover, the increment is upper bounded by the expected logarithm of one minus the quantization error. Finally, simulation shows that feedback control increases throughput of the conventional periodic feedback by up to 0.5 bit/s/Hz without requiring additional bandwidth or antennas.
UniRef clusters: a comprehensive and scalable alternative for improving sequence similarity searches (2014)

Intra-cluster molecular function consistency was examined by analysis of Gene Ontology terms. Results show that UniRef clusters bring together proteins of identical molecular function in more than 97% of the clusters, implying that clusters are useful for annotation and can also be used to detect annotation inconsistencies. To examine coverage in similarity results, BLASTP searches against UniRef50 followed by expansion of the hit lists with cluster members demonstrated advantages compared with searches against UniProtKB sequences; the searches are concise (∼7 times shorter hit list before expansion), faster (∼6 times) and more sensitive in detection of remote similarities (>96% recall at e-value <0.0001). Our results support the use of UniRef clusters as a comprehensive and scalable alternative to native sequence databases for similarity searches and reinforces its reliability for use in functional annotation.
Compulsory Zionism and Palestinian Existence: A Genealogy (2022)

This essay offers a genealogy of the phrase “compulsory Zionism” in order to illuminate its vexed and contradictory intellectual foundations, the ethical and political stakes of the discourse surrounding the phrase, and its accompanying racial project. Scholars of late have taken up the use of this phrase to signal how “common-sense” knowledge about Palestine and Israel is naturalized in ways that privilege Israel and subjugate Palestinian existence. However, I argue that the phrase is also useful for understanding how Palestine solidarity politics are micromanaged within transnational leftist social justice movements and academia.
A semantic framework for modelling quotes in email conversations (2010)

Quoting is a common practice in online conversations, notably in email discussions and bulletin boards. Despite many applications that offer special functionalities to handle them, there is no agreement on how to semantically represent these quotes, so that they could be queried and analysed uniformly whatever the original application is. While various Semantic Web models, notably SIOC, have become popular for interlinking, exporting and exchanging information about online communities and their conversations, they do not provide means to model such quotes. In this paper, we present (i) an OWL2 extension of SIOC for representing quotes and (ii) a framework for automated quotes extraction from email archives. In addition, we demonstrate the utility of such formal representation for querying email archives with finer-grained queries and for mining social networks based on the argumentative structure of email conversations.
Drug resistant tuberculosis in Estonia. (1998)

The incidence of drug resistance in M. tuberculosis is high in Estonia.
Safely and Efficiently Updating References During On-line Reorganization (1998)

With today&apos;s demands for continuous availability of mission-critical databases, on-line reorganization is a necessity. In this paper we present a new on-line reorganization algorithm which defers secondary index updates and piggybacks them with user transactions. In addition to the significant reduction of the total I/O cost, the algorithm also assures that almost all the database is available all of the time and that the reorganization is interruptible and restartable. We believe that the technique presented in this paper could be used for improving normal database update performance as well.
Sequencing of bulks of segregants allows dissection of genetic control of amylose content in rice (2017)

Amylose content (AC) is a key quality trait in rice. A cross between Oryza glaberrima (African rice) and Oryza sativa (Asian rice) segregating for AC was analysed by sequencing bulks of individuals with high and low AC. SNP associated with the granule bound starch synthase (GBSS1) locus on chromosome 6 were polymorphic between the bulks. In particular, a G/A SNP that would result in an Asp to Asn mutation was identified. This amino acid substitution may be responsible for differences in GBSS activity as it is adjacent to a disulphide linkage conserved in all grass GBSS proteins. Other polymorphisms in genomic regions closely surrounding this variation may be the result of linkage drag. In addition to the variant in the starch biosynthesis gene, SNP on chromosomes 1 and 11 linked to AC was also identified. SNP was found in the genes encoding the NAC and CCAAT-HAP5 transcription factors that have previously been linked to starch biosynthesis. This study has demonstrated that the approach of sequencing bulks was able to identify genes on different chromosomes associated with this complex trait.
Yeast whole glucan particle (WGP) β-glucan in conjunction with antitumour monoclonal antibodies to treat cancer (2005)

Beta-glucans, biological response modifiers (BRMs) derived from the cell walls of yeast and other sources, have been demonstrated to prime leukocyte complement receptor 3 (CR3), thus enabling these cells to kill tumours opsonised with complement fragment iC3b. Many tumours activate complement via the classical pathway mediated by antitumour monoclonal antibodies (mAbs) or natural antibodies. Studies into the cellular and molecular mechanisms of action have demonstrated that orally administrated yeast beta-glucans are ingested and processed by macrophages. These macrophages secrete the active moiety that primes neutrophil CR3 to kill iC3b-opsonised tumour cells. Extensive studies in preclinical animal tumour models have demonstrated the efficacy of combined oral particulate yeast beta-glucan with antitumour mAb therapy in terms of tumour regression and long-term survival. It is proposed that the addition of beta-glucan will further improve the clinical therapeutic efficacy of antitumour mAbs in cancer patients.
Aging human RPE: morphometric analysis of macular, equatorial, and peripheral cells. (1984)

Retinal pigment epithelium (RPE) of 50 human eyes, five from each 10 decades of life, were analyzed using ultrastructural morphometric techniques. Content of three types of pigments, lipofuscin, melanin, and complex granules, (melanolipofuscin, melanolysosomes) were recorded for cells from macular, equatorial, and peripheral retinal specimens. Areas occupied by pigments, nucleus, and cytoplasmic space were calculated. Data were analyzed by a computer for age-related changes and effects of fixation delay time. The largest increase in lipofuscin granules occurred between the first and second decade of life, and further increases occurred with age. The content of "pure" melanin declined with age, whereas the number of complex melanin granules increased. Macular RPE contained more complex granules than nonmacular RPE, particularly in young eyes. The volume of RPE cytoplasm not occupied by pigments ("free space") decreased with age. No significant effects of fixation delays between 2 and 9 hours postmortem were found on the parameters studied here. These findings may serve as a baseline for estimating normalcy of human RPE specimens.
KONDENSATORMODUL FUER KRAFTFAHRZEUG-KLIMAANLAGEN (1995)

Um die Akzeptanz von Fahrzeug-Klimaanlagen langfristig zu sichern und deren weitere Verbreitung zugunsten der Fahrsicherheit und des Komforts zu foerdern, muss der Umweltaspekt bei Klimaanlagen weiter im Mittelpunkt der Entwicklungsaktivitaeten stehen. Vorgestellt wird der Nocolok-geloetete Flachrohrkondensator der Firma Behr. Er ist heute Stand der Technik und wird in hoher Stueckzahl produziert. Der Flachrohrkondensator bildet die Grundlage fuer die Weiterentwicklung zu einem Modul, das den Kondensator, den Sammler mit wechselbarem Filter/Trockner und optionalem Fuellstandssensor und eine Unterkuehlstrecke zur gezielten Unterkuehlung des Kaeltemittels in einer Baueinheit zusammenfasst. Das Konzept reduziert sowohl die beim Automobilhersteller anfallenden Produktions-, Logistik- und Montageaufwendungen als auch die benoetigte Kaeltemittelmenge. Der Endkunde profitiert von einem optimalen Leistungs- und Komfortverhalten, das ueber einen groesseren Fuellmengenbereich und damit laengeren Zeitraum hinweg in vollem Umfang erhalten bleibt.

Variations of Blood Pressures in Lean Zucker Rats Fed Low or High Fat Diets (1995)

The purpose of this study was to determine whether lean (Fa/?) Zucker rats which exhibit greater metabolic efficiency in response to a high (48%) fat diet also exhibit hypertension.Twenty-nine lean (Fa/?) and eleven obese (fa/fa) Zucker rats were fed low (12% energy) and high (48% energy) fat diets. Food intake and weight change were recorded weekly to obtain an index of energy efficiency. After 6 wk, direct intra-arterial blood pressure was measured in conscious, unrestrained animals. Arterial blood was collected for analyses of plasma insulin and glucose. The high fat diet had no effect on blood pressure in obese rats, although obese animals fed both diets had significantly higher blood pressure than lean siblings. High fat feeding in lean rats unmasked a heterogeneity in blood pressure. Blood pressure in this group was significantly correlated with weight change, energy efficiency ratio and plasma glucose concentration. Lean rats fed the high fat diet with blood pressures above the group median exhibited significantly greater plasma insulin (P < 0.02) and glucose (P < 0.01) concentration and energy efficiency ratios (P < 0.01) than those with lower blood pressures. Thus, it appears that there were two groups of lean animals present, one of which was more phenotypically sensitive to high fat feeding than the other. This suggests a possible gene dosage effect of the fa allele in the Zucker rat model.
The Yeast Vacuolar Proton-translocating ATPase Contains a Subunit Homologous to the Manduca sexta and Bovine e Subunits That Is Essential for Function (2004)

The yeast cwh36Delta mutant was identified in a screen for yeast mutants exhibiting a Vma(-) phenotype suggestive of loss of vacuolar proton-translocating ATPase (V-ATPase) activity. The mutation disrupts two genes, CWH36 and a recently identified open reading frame on the opposite strand, YCL005W-A. We demonstrate that disruption of YCL005W-A is entirely responsible for the Vma(-) growth phenotype of the cwh36Delta mutant. YCL005W-A encodes a homolog of proteins associated with the Manduca sexta and bovine chromaffin granule V-ATPase. The functional significance of these proteins for V-ATPase activity had not been tested, but we show that the protein encoded by YCL005W-A, which we call Vma9p, is essential for V-ATPase activity in yeast. Vma9p is localized to the vacuole but fails to reach the vacuole in a mutant lacking one of the integral membrane subunits of the V-ATPase. Vma9p is associated with the yeast V-ATPase complex in vacuolar membranes, as demonstrated by co-immunoprecipitation with known V-ATPase subunits and glycerol gradient fractionation of solubilized vacuolar membranes. Based on this evidence, we propose that Vma9p is a genuine subunit of the yeast V-ATPase and that e subunits may be a functionally essential part of all eukaryotic V-ATPases.
Bevacizumab induces regression of vestibular schwannomas leading to improved hearing in neurofibromatosis type 2 patients (2009)

Bilateral vestibular schwannomas are the hallmark of neurofibromatosis type 2 which impair hearing and lead frequently to deafness. Neurosurgical intervention, the only established treatment, often damages the vestibular nerve. We report two cases in which 3- and 6-month treatment of bevacizumab induced significant regression of progressive vestibular schwannomas by over 40% and improved hearing significantly in the patient treated for 6 months. Bemacizumab-therapy may thus provide an effective treatment for progressive vestibular schwannomas in neurofibromatosis type 2 patients.
WDM network architecture (1993)

Wavelength division multiplexed (WDM) optical networks are being explored with the goal of exploiting the broad optical band of low loss in optical fibers to provide new network architectures that are more flexible, optically transparent (all-optical), and survivable, and that have a higher capacity and performance than traditional means. Early network architectures were largely based on the passive broadcast star, and used tunable lasers, receivers, or both to establish noninterfering channels over this transparent shared medium.
Proinflammatory cytokine and chemokine modulation by<i>Streptococcus suis</i>in a whole-blood culture system (2006)

Streptococcus suis is an important swine and human pathogen. Inflammation, a hallmark of S. suis infection, is thought to be responsible for most clinical signs of meningitis, septicaemia and sudden death. In this work, using a porcine whole blood model, S. suis serotype 2 was shown to trigger the release of several pro-inflammatory cytokines as evaluated by reverse transcriptase-PCR and enzyme-linked immunosorbent assay. Although individual variations were observed among different S. suis strains, no correlations were observed between the strain origin/phenotype and cytokine levels. Live bacteria induced higher tumour necrosis factor alpha, interleukin-1 beta (IL-1beta) and IL-6 levels than did heat-killed bacteria. In contrast, heat-killed bacteria stimulated higher levels of IL-8 and monocyte chemotactic protein one (MCP-1). The bacterial cell wall was observed to be the major cytokine-inducting components, whereas capsule expression was important for MCP-1 activation. The presence of specific antibodies suppressed bacterial growth resulting in significantly reduced levels of cytokine production. Thus, antibody-mediated bacterial phagocytosis combined with suppressed inflammation may be beneficial for infection control strategies. We provide first evidence of S.suis-induction of pro-inflammatory swine cytokines and demonstrate the strength and relevance of the whole blood culture systems in the investigation of S. suis modulation of cytokine production.
Next generation wireless networks (2002)

The market for wireless telecommunications infrastructure equipment is expected to continue to grow at an astonishing pace. Projections show the market for infrastructure equipment and support services increasing at a 20% compounded annual growth rate until the year 2000. Factors that contribute to this growth include the deregulation in telecommunications markets on a global scale; rapidly growing economies and an insatiable appetite for telecommunication services; decreasing terminal costs; migration of analog networks to digital networks; and increased competition among service providers and the resulting need for differentiated services. The network infrastructure to support new wireless services must continue to evolve for base station and network switching and control systems. This paper discusses the next generation of wireless communications infrastructure products designed and manufactured by Lucent Technologies that will provide end users with a wide range of wireless access and advanced services.
Impact of α-d-glucose pentaacetate on the selective separation of CO2 and SO2 in supported ionic liquid membranes (2012)

A biocompatible, nontoxic, and nonvolatile compound, α-D-glucose pentaacetate (GPA), was impregnated in supported ionic liquid membranes (SILMs) and used for the selective separation of CO2 and SO2. It was found that GPA could cooperate with [Bmim][BF4] to influence the permeability of CO2 and enhance the CO2/N2 selectivity. Further permeation experiments demonstrated that the addition of GPA could reduce the permeability of N2 in the SILMs and thereby improve the CO2/N2 and SO2/N2 selectivities. The highest CO2/N2 selectivity obtained in the paper is 79 ± 0.9 for dry gas and 86 ± 1.6 for humidified gas, and the highest SO2/N2 selectivity is 686 ± 19.8 for dry gas. This environmentally benign separation process with high gas permeability and good selectivity may be expected to have a potential application for the separation of CO2 and SO2 from a flue gas stream.
On the precursor in laser-generated ultrasound waveforms in metals (1990)

A laser pulse, when focused on a metal sample, produces characteristic elastic waveforms, which depend on whether thermoelastic or ablative/evaporative mechanisms dominate the generation process. In the thermoelastic regime, with an unconstrained surface, the predominant axial displacement is opposite to the direction of propagation (negative), but there is typically a small transient positive displacement. This precursor is not predicted by elastic point source models, but is predicted by models including thermal diffusion. A recent formulation of pulsed photoacoustic generation is used to show how the precursor arises from interaction of the thermal and elastic modes at the illuminated surface.
Plumbagin inhibits invasion and migration of liver cancer HepG2 cells by decreasing productions of matrix metalloproteinase‐2 and urokinase‐ plasminogen activator (2009)

We demonstrated the inhibitory effects of plumbagin on the invasion, migration and adhesion of HepG2 cells, while plumbagin treatment may decrease the expressions of MMP-2 and u-PA and enhance the expressions of TIMP-2 and PAI-1.
Improved color coordinates of green monochromatic pc-LED capped with a band-pass filter (2013)

This study introduces a "greener" green monochromatic phosphor-converted light-emitting diode (pc-LED) using a band-pass filter (BPF) combined with a long-pass dichroic filter (LPDF) and a short-pass dichroic filter (SPDF) to improve the color quality of our previously developed LPDF-capped green pc-LED. This can also address the drawbacks of III-V semiconductor-type green LEDs, which show a low luminous efficacy and a poor current dependence of the efficacy and color coordinates compared to blue semiconductor-type LEDs. The optical properties of green monochromatic pc-LEDs using a BPF are compared with those of LPDF-capped green pc-LEDs, which have a broad band spectrum, and III-V semiconductor-type green LEDs by changing the transmittance wavelength range of the BPF and the peak wavelength of the green phosphors. BPF-capped green monochromatic pc-LEDs provide a high luminous efficacy (134 lm/W at 60 mA), and "greener" 1931 Commission Internationale d'Eclairage (CIE; CIEx, CIEy) color coordinates (0.24, 0.66) owing to the narrowed emission spectrum. We also propose a two-dimensional (2D) polystyrene (PS) microbead (2-μm diameter) monolayer as a scattering layer to overcome the poor angular dependence of the color coordinates of the transmitted light through a nano-multilayered dichroic filter such as an LPDF or BPF. The 2D PS scattering layer improves the angular dependence of the green color emitted from a BPF-capped green pc-LED with only 3% loss of luminous efficacy.
A Hierarchical Self-Regulation Control for Economic Operation of AC/DC Hybrid Microgrid With Hydrogen Energy Storage System (2019)

The introduction of hydrogen energy storage system (HESS) as a potential form of energy storage systems (ESSs) has a significant impact on original control and operation. This paper presents a hierarchical self-regulation control method, which can be divided into the supervisory layer and local layer control. The supervisory layer control decides the output power of ESSs, according to the operation cost function so that the system can reach economic optimum during the operation process. The local layer control adopts virtual inertia control with global power support to improve system stability. First, a HESS model composed of an electrolyzer, hydrogen storage tank, and the fuel cell is established. SOCH of hydrogen tank is defined to express produced and consumed hydrogen. Then, aiming at supervisory layer control, operation cost functions of battery energy storage system (BESS) and HESS under different operation modes are built. Virtual inertia of ac ESS and virtual capacitance of dc ESS are introduced for local layer control. Finally, the simulation results based on the RT-LAB platform of both 24-h operation case and step power change case verify the correctness of the proposed method. The comparison with only droop control method shows that the proposed method can achieve the lowest operation cost and improve system inertia.
Seamless reconfiguration of time triggered ethernet based protocols (2015)

One of the key aspects to consider increasing flexibility of production plants is the industrial communication system. In case of time triggered Ethernet (TTE) systems, the flexibility is typically limited. In this paper an approach for seamless reconfiguration of TTE system is proposed. It has been shown that the reconfiguration can be performed without influencing currently running system.
Selective CH Functionalization of Methane, Ethane, and Propane by a Perfluoroarene Iodine(III) Complex (2014)

Direct partial oxidation of methane, ethane, and propane to their respective trifluoroacetate esters is achieved by a homogeneous hypervalent iodine(III) complex in non-superacidic (trifluoroacetic acid) solvent. The reaction is highly selective for ester formation (>99%). In the case of ethane, greater than 0.5 M EtTFA can be achieved. Preliminary kinetic analysis and density functional calculations support a nonradical electrophilic CH activation and iodine alkyl functionalization mechanism.
MAGNAMOSIS IV: magnetic compression anastomosis for minimally invasive colorectal surgery (2013)

MAGNAMOSIS was feasible in performing a hybrid NOTES colorectal anastomosis. It has the advantage over circular staplers of precise endoscopic delivery throughout the entire colon. SSA was reliable and effective. A minimum initial compression force of 4 N appears to be required for reliable magnetic anastomoses.
