Demodulation of cochannel QAM signals (2003)

The authors describe a technique for demodulating a quadrature amplitude modulated (QAM) signal in the presence of a second cochannel QAM interferer and intersymbol interference. The method consists of a two-step procedure whereby tentative estimates of both the desired and interfering signals are made and then converted into final estimates by detecting and correcting errors. The tentative decisions are formed using a structure consisting of a primary demodulator followed by a secondary demodulator incorporating an adaptive interference canceller. Errors in the tentative decisions are detected using an adaptive channel estimator and then corrected using a maximum-likelihood sequence estimator. Signature curves quantifying the symbol error rate of the tentative demodulator as a function of signal-to-noise ratio and signal-to-interference ratio are presented. A simulation of the error detection/correction method is also presented. Simulations indicate that the method will yield substantial improvement in performance relative to conventional demodulation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
TAL1 and LIM-Only Proteins Synergistically Induce Retinaldehyde Dehydrogenase 2 Expression in T-Cell Acute Lymphoblastic Leukemia by Acting as Cofactors for GATA3 (1998)

Previously, we have shown that TAL1 and the LIM-only protein gene (LMO) are regularly coactivated in T-cell acute lymphoblastic leukemia (T-ALL). This observation is likely to relate to the findings that TAL1 and LMO are highly synergistic in T-cell tumorigenesis in double-transgenic mice. To understand the molecular mechanisms of functional synergy between TAL1 and LMO in tumorigenesis and transcriptional regulation, we tried to identify downstream target genes regulated by TAL1 and LMO by a subtractive PCR method. One of the isolated genes, that for retinaldehyde dehydrogenase 2 (RALDH2), was regularly expressed in most of the T-ALL cell lines that coexpressed TAL1 and LMO. Exogenously transfected TAL1 and LMO, but not either alone, induced RALDH2 expression in a T-ALL cell line, HPB-ALL, not expressing endogeneous TAL1 or LMO. The RALDH2 transcripts in T-ALL were, however, mostly initiated within the second intron. Promoter analysis revealed that a GATA site in a cryptic promoter in the second intron was essential and sufficient for the TAL1- and LMO-dependent transcriptional activation, and GATA3 binds to this site. In addition, forced expression of GATA3 potentiated the induction of RALDH2 by TAL1 and LMO, and these three factors formed a complex in vivo. Furthermore, a TAL1 mutant not binding to DNA also activated the transcription of RALDH2 in the presence of LMO and GATA3. Collectively, we have identified the RALDH2 gene as a first example of direct transcriptional target genes regulated by TAL1 and LMO in T-ALL. In this case, TAL1 and LMO act as cofactors for GATA3 to activate the transcription of RALDH2.
Role of liver progenitors in liver regeneration. (2015)

During massive liver injury and hepatocyte loss, the intrinsic regenerative capacity of the liver by replication of resident hepatocytes is overwhelmed. Treatment of this condition depends on the cause of liver injury, though in many cases liver transplantation (LT) remains the only curative option. LT for end stage chronic and acute liver diseases is hampered by shortage of donor organs and requires immunosuppression. Hepatocyte transplantation is limited by yet unresolved technical difficulties. Since currently no treatment is available to facilitate liver regeneration directly, therapies involving the use of resident liver stem or progenitor cells (LPCs) or non-liver stem cells are coming to fore. LPCs are quiescent in the healthy liver, but may be activated under conditions where the regenerative capacity of mature hepatocytes is severely impaired. Non-liver stem cells include embryonic stem cells (ES cells) and mesenchymal stem cells (MSCs). In the first section, we aim to provide an overview of the role of putative cytokines, growth factors, mitogens and hormones in regulating LPC response and briefly discuss the prognostic value of the LPC response in clinical practice. In the latter section, we will highlight the role of other (non-liver) stem cells in transplantation and discuss advantages and disadvantages of ES cells, induced pluripotent stem cells (iPS), as well as MSCs.
Selective CO<sub>2</sub> Reduction to CO in Water using Earth-Abundant Metal and Nitrogen-Doped Carbon Electrocatalysts (2018)

Earth-abundant transition metal (Fe, Co, or Ni) and nitrogen-doped porous carbon electrocatalysts (M-N-C, where M denotes the metal) were synthesized from cheap precursors via silica-templated pyrolysis. The effect of the material composition and structure (i.e., porosity, nitrogen doping, metal identity, and oxygen functionalization) on the activity for the electrochemical CO2 reduction reaction (CO2RR) was investigated. The metal-free N-C exhibits a high selectivity but low activity for CO2RR. Incorporation of the Fe and Ni, but not Co, sites in the N-C material is able to significantly enhance the activity. The general selectivity order for CO2-to-CO conversion in water is found to be Ni > Fe ≫ Co with respect to the metal in M-N-C, while the activity follows Ni, Fe ≫ Co. Notably, the Ni-doped carbon exhibits a high selectivity with a faradaic efficiency of 93% for CO production. Tafel analysis shows a change of the rate-determining step as the metal overtakes the role of the nitrogen as the most active site. Recording the X-ray photoelectron spectra and extended X-ray absorption fine structure demonstrates that the metals are atomically dispersed in the carbon matrix, most likely coordinated to four nitrogen atoms and with carbon atoms serving as a second coordination shell. Presumably, the carbon atoms in the second coordination shell of the metal sites in M-N-C significantly affect the CO2RR activity because the opposite reactivity order is found for carbon supported metal meso-tetraphenylporphyrin complexes. From a better understanding of the relationship between the CO2RR activity and the material structure, it becomes possible to rationally design high-performance porous carbon electrocatalysts involving earth-abundant metals for CO2 valorization.

High-resolution separation and accurate size determination of pulsed-field gel electrophoresis of DNA. 4. Influence of DNA topology (1988)

Pulsed-field gel electrophoresis is a powerful technique for the fractionation of linear DNA molecules with sizes above 50 kilobase pairs (kb). Here it is demonstrated that this technique is also effective for separating smaller DNAs including linear, circular, and supercoiled species. The mobilities of linear DNAs larger than 8 kb can be modulated by pulse times between 0.1 and 100 s. The mobility of supercoiled DNA molecules up to 16 kb is generally unaffected by these pulse times except that 10-s pulse times cause a small but distinct increase in the mobility. The general insensitivity of small supercoiled DNAs to pulse time presumably occurs because these species reorient so rapidly that they spend most of their time undergoing conventional electrophoresis. However, the mobilities of larger supercoiled DNAs are affected by pulse times of less than 1 s, and at 0.1 s the molecules are better resolved by pulsed electrophoresis than by ordinary electrophoresis. The mobility of 3-19 kb nicked and relaxed circular DNA molecules is also affected by pulse time but in a complex way.
Social networking for well-being (2011)

In this paper, we present some of the work that is being done in the WeCare project (in the AAL programme). The projectâs goal is to introduce social networking services in the lives of older people, in order to improve their well-being. Participation in social networks, both online and âin real lifeâ will help them to stay in touch with family and friends and to meet new people. The project follows a human-centred design approach and is organized in close cooperation with older people and organizations that represent older people. A social networking services is developedâor, actually, four versions of this service, for four countries: Finland, Spain, Ireland and The Netherlands. Furthermore, pilots are organized to evaluate the added value of these services [i]n peopleâs daily lives. Before and after the pilots, participantsâ experiences of well-being are surveyed to study the effects of using the social networking services. Moreover, based on Social Capital Theory, seven positive habits are articulated that will help people to participate effectively in social networking, thereby empowering them to improve their social well-being. These habits will be evaluated during the pilots and, later on, will be translated into practical recommendations for policy makers and for service developers.
Traveling‐wave ion mobility mass spectrometry of protein complexes: accurate calibrated collision cross‐sections of human insulin oligomers (2012)

Accurate T-wave Ω-values that are indistinguishable from drift-tube values are obtained when using (1) native-like calibrants with masses that closely bracket that of the analyte, (2) T-wave velocities that maximize the R(2) of the calibration plot for those calibrants, and (3) at least three replicates at T-wave velocities that yield calibration plots with high R(2).

Identification and fine mapping of quantitative trait loci for growth traits on bovine chromosomes 2, 6, 14, 19, 21, and 23 within one commercial line of Bos taurus1 (2004)

We report the identification and fine mapping of QTL for birth weight (BWT), preweaning ADG (PWADG), and postweaning ADG on feed (ADGF) in a commercial line of Bos taurus using an identical-by-descent haplotype sharing method. One hundred seventy-six calves of 12 bulls (9 to 30 male calves from each sire) of the Beefbooster, Inc., M1 line were typed using 71 genetic markers from bovine chromosomes (BTA) 2, 6, 14, 19, 21, and 23 (8 to 16 markers from each chromosome). Sixteen haplotypes were found to have significant (P <0.05) associations with BWT at the comparison-wise threshold. The 16 haplotypes span 13 chromosomal regions, two on BTA 2 (9.1 to 22.5 cM and 95.0 to 100.3 cM), three on BTA 6 (8.2 to 11.8 cM, 35.5 to 49.7 cM, and 83.0 to 86.2 cM), three on BTA 14 (26.0 to 26.7 cM, 36.2 to 46.2 cM, and 52.0 to 67.7 cM), one on BTA 19 (52.0 to 52.7 cM), two on BTA 21 (9.9 to 20.4 cM and 28.2 to 46.1 cM), and two on BTA 23 (23.9 to 36.0 cM and 45.1 to 50.9 cM). Thirteen haplotypes spanning seven chromosomal regions significantly affected (P <0.05) PWADG at the comparison-wise threshold. The seven chromosomal regions include two regions on BTA 6 (11.8 to 44.2 cM and 83.0 to 86.2 cM), one on BTA 14 (26.7 to 50.8 cM), one on BTA 19 (4.8 to 15.9 cM), one on BTA 21 (9.9 to 20.4 cM), and two on BTA 23 (17.3 to 36.0 cM and 45.1 to 50.9 cM). For ADGF, 11 haplotypes were identified to have significant associations (P <0.05) at the comparison-wise threshold. The 11 haplotypes represented eight chromosomal regions, one on BTA 2 (9.1 to 22.5 cM), two on BTA 6 (49.7 to 50.1 cM and 59.6 to 63.6 cM), two on BTA 14 (17.0 to 24.0 cM and 36.2 to 46.2 cM), two on BTA 19 (52.0 to 52.7 cM and 65.1 to 65.7 cM), and one on BTA 21 (46.1 to 53.1 cM). The QTL regions identified and fine mapped in this study will provide a reference for future positional candidate gene research and marker-assisted selection of various growth traits.
Investigation of How Neural Networks Learn From the Experiences of Peers Through Periodic Weight Averaging (2017)

We investigate a method, weighted average model fusion, that enables neural networks to learn from the experiences of other networks, as well as from their own experiences. This method is inspired by the the Social natural of humans, which has been shown to be one of the biggest factors in the development of our cognitive abilities. Modern machine learning has focuses predominantly on learning from direct training, and has largely ignored learning through Social engagement with peers, neural networks will the same topology. In order to explore learning through engagement with peers, we have created a way for neural networks to teach each other. Our method allows neural networks to exchange knowledge by combining their weights. It calculates a pairwise weighted average of the weights of two neural networks, and then replaces the existing weight with the new value. We find that weighted average model fusion successfully enables neural networks to learn from the experiences of their peers and combine it with the knowledge that is gained from its own individual experiences. Additionally, we explore the effects that several meta-parameters have on model fusion to provide deeper insights into how the behaves in a variety of scenarios.
Broadband planar antenna having round corner rectangular wide slot (2003)

A round corner rectangular wide slot antenna is proposed with a novel feeding geometry to have better wideband characteristics than a normal rectangular wide slot antenna. The input impedances of slots with various geometries were calculated and the antenna having the best result was fabricated for verification. The measured bandwidth of the antenna is almost two octaves (2.08 GHz to 8.25 GHz) with VSWR<2.
Biomechanics of curved surgical needle bending (1989)

Because needle bending resistance is such an important factor in the selection of surgical needles, a standard quantitative test of needle bending has been devised to study the biomechanics of deformation of needles from three different commercial manufacturers. The superior resistance to deformation of needles made by one manufacturer has been related to the specific alloy, ASTM 45500 stainless steel, employed in its production. The needles produced from ASTM stainless steel 45500 have stronger tensile and yield strengths than those of the other alloys, accounting for their greater resistance to bending.

Suppressors of the secY24 mutation: identification and characterization of additional ssy genes in Escherichia coli (1986)

We previously reported (Shiba et al., J. Bacteriol. 160:696-701, 1984) the isolation and characterization of the mutation (ssy) that suppresses the protein export defect due to the secY24(Ts) mutation and causes cold-sensitive growth of Escherichia coli. This report describes more systematic isolation of ssy mutations. Among temperature-resistant revertants of the secY24 mutant, 65 mutants were found to be cold sensitive. These cold-sensitive mutations have been classified by genetic mapping. Twenty-two mutations fell into the ssyA class previously described. The remaining mutations were located at five new loci: ssyB at 9.5 min between tsx and lon; ssyD around 3 min; ssyE at 72.5 min near secY; ssyF at 20.5 min within rpsA; and ssyG at 69.0 min near argG. Two predominant classes, ssyA and ssyB, are probably affected in protein synthesis at the elongation step, whereas the ssyF mutant contained an altered form of ribosomal protein S1 (the gene product of rpsA). These cold-sensitive ssy mutations which suppress secY24 may define genes whose function is somehow involved in the secY-dependent protein secretion mechanism. However, the existence of multiple suppressor loci makes it unlikely that all of these genes specify additional components of the export machinery. A delicate balance may exist between the systems for synthesizing and exporting proteins.
Multicontact Interaction Force Sensing From Whole-Body Motion Capture (2017)

We present a novel technique that unobtrusively estimates forces exerted by human participants in multicontact interaction with rigid environments. Our method uses motion capture only, thus circumventing the need to set up cumbersome force transducers at all potential contacts between the human body and the environment. This problem is particularly challenging, as the knowledge of a given motion only characterizes the resultant force, which can generally be caused by an infinity of force distributions over individual contacts. We collect and release a large-scale dataset on how humans instinctively regulate interaction forces on diverse multicontact tasks and motions. The force estimation framework we propose leverages physics-based optimization and neural networks to reconstruct force distributions that are physically realistic and compatible with real interaction force patterns. We show the effectiveness of our approach on various locomotion and multicontact scenarios.
Development of Lake Assessment Methods Based Upon the Aquatic Ecoregion Concept (1989)

ABSTRACT The development of practical lake management strategies in Minnesota has been greatly facilitated by using the aquatic ecoregion approach and standard assessment methodologies (models). Previous studies have shown the significance of the aquatic ecoregion in determining lake water quality patterns, water quality attainability, and development of nutrient criteria (Heiskary et al. 1987; Heiskary and Walker, 1988). This paper focuses upon the use of ecoregion data for modeling purposes. The Minnesota Lake Eutrophication Analysis Procedure (MINLEAP) is a computer program designed to predict eutrophication indices in Minnesota lakes based upon area watershed, depth, and ecoregion. Ecoregion is used to predict runoff and average stream phosphorus concentration. The program formulates water and phosphorus balances and uses a network of empirical models to predict lake phosphorus, chlorophyll a, and transparency values. The program is intended primarily as a screening tool for estimating lake conditions with minimal input data and for identifying “problem” lakes. Included in the program output are: (1) statistical comparisons of observed and predicted phosphorus, chlorophyll a, and transparency values; (2) uncertainty estimates; and (3) estimates of chlorophyll a interval frequencies (nuisance frequencies), for observed and predicted conditions. These expressionsof lake condition may be calibrated to citizen preferences using observer surveys (Heiskary and Walker, 1988) to define swimmable and nonswimmable conditions in a locally meaningful manner. The model should be used to approximate lake water quality expectations acknowledging that individual lakes may deviate greatly from regionally defined patterns.

Sinergism among auxins, gibberellins and cytokinins in tomato cv. Micro-Tom (2013)

Plant development results from the combination of many signals, and from interactions and crosstalks among them. The aim of this study was to evaluate the effect of isolated and combined applications of gibberellic acid (GA) (gibberellin), indolbutyric acid (IBA) (auxin) and KN (cytokinin) on vegetative (dry matter mass of the shoot and root, and the ratio of these two organs) and reproductive development (fresh and dry matter mass of fruits and fruit size) of tomato test plants ( Solanum lycopersicum L. cv. Micro-Tom), to better elucidate the interactions among these hormonal classes. The following treatments were accomplished through foliar application: GA (5 mg L -1 ); IBA (5 mg L -1 ); KN (9 mg L -1 ); GA + IBA (5 mg L -1 + 5 mg L -1 ); GA + KN (5 mg L -1 + 9 mg L -1 ); IBA + KN (5 mg L -1 + 9 mg L -1 ); GA + IBA + KN (5 mg L -1 + 5 mg L -1 + 9 mg L -1 ) and Stimulate® (ten times diluted). Plants from the control were sprayed with water. Stimulate®, liquid formulation containing KN (90 mg L -1 ), GA (50 mg L -1 ) and IBA (50 mg L -1 ). Some combined applications of GA, IBA and KN or Stimulate® promoted significant increases in the dry matter accumulation of roots and fresh and dry matter mass of fruit compared to the control. Besides the perspective to extend such results for commercial tomato production, the relevance of known hormonal interactions for the results obtained is discussed.
Deformation-Induced Phase Transition and Superstructure Formation in Poly(ethylene terephthalate) (2004)

Deformation-induced phase transitions and superstructure formation in poly(ethylene terephthalate) (PET) were studied by means of in-situ synchrotron small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD) as well as Raman spectroscopy. The deformation conditions involved uniaxial stretching of quenched PET films at a temperature just below its glass transition temperature (Tg), where a notable “plastic deformation” stage was observed. WAXD results indicated that the initial sample contained a “slush” structure (amorphous + nematic), whereby deformation induced oriented amorphous, nematic, smectic (C and quasi-A), and stable triclinic crystalline phases. SAXS results indicated that the fibrillar superstructure was formed upon the formation of oriented slush. In-situ Raman spectroscopic data revealed the orientation information on ethylene glycol and benzene ring as well as the gauche−trans transition in deformation of PET chains, which are in good agreement with X-ray results. A mechanism for deformation-induced phase transitions and for hierarchical structure formation has been proposed to correlate the structural information with the mechanical properties.
