Biometrical studies on characteristics of plagiotropic branches in Coffea arabica L. cultivated with high plant density (2014)

The great demand for improvements in productivity lead to the search of new information regarding the behaviour of new cultivars of arabica coffee. Improved genotypes need be studied in specific regions to evaluate their potential, such as the exploration on mountains, aiming to define variables that can be exploited for the study and selection of genotypes in those conditions. This study aimed to evaluate the genetic diversity of genotypes of Coffea arabica L. with the potential for cultivation in increased-density systems in the region of Caparaó (state of Espírito Santo, Brazil), based on the characteristics of plagiotropic branches in production, to evaluate the existence of correlations and to estimate the relative contributions of each of the aforementioned characteristics to the diversity. To this end, 25 characteristics were determined in 16 genotypes of arabica coffee cultivated under competition of density (evaluated in 2013, with the stabilisation of their reproductive phenological cycle). These genotypes presented considerable diversity for almost all of the traits, being possible to separate seven groups of genotypes. Among the genotypes cultivated with high plant density, IAPAR 59 and Catiguá MG2 presented a greater degree of dissimilarity. Of the 25 traits, the number of fruits per branch and the biomass contributed more to the variability among the genotypes (over 95% of accumulated contribution). A total of 111 significant correlations were observed, with values over |0.60| in 78% of cases. Strong positive and negative correlations are observed between the various characteristics, revealing the possibility of the simultaneous selection of correlated traits.
Maximizing Performance Under a Power Cap (2016)

Power and thermal dissipation constrain multicore performance scaling. Modern processors are built such that they could sustain damaging levels of power dissipation, creating a need for systems that can implement processor power caps. A particular challenge is developing systems that can maximize performance within a power cap, and approaches have been proposed in both software and hardware. Software approaches are flexible, allowing multiple hardware resources to be coordinated for maximum performance, but software is slow, requiring a long time to converge to the power target. In contrast, hardware power capping quickly converges to the the power cap, but only manages voltage and frequency, limiting its potential performance. In this work we propose PUPiL, a hybrid software/hardware power capping system. Unlike previous approaches, PUPiL combines hardware's fast reaction time with software's flexibility. We implement PUPiL on real Linux/x86 platform and compare it to Intel's commercial hardware power capping system for both single and multi-application workloads. We find PUPiL provides the same reaction time as Intel's hardware with significantly higher performance. On average, PUPiL outperforms hardware by from 1:18-2:4 depending on workload and power target. Thus, PUPiL provides a promising way to enforce power caps with greater performance than current state-of-the-art hardware-only approaches.
Dynamic Dual-Output Diffusion Models (2022)

Iterative denoising-based generation, also known as denoising diffusion models, has recently been shown to be comparable in quality to other classes of generative models, and even surpass them. Including, in particular, Generative Adversarial Networks, which are currently the state of the art in many sub-tasks of image generation. However, a major drawback of this method is that it requires hundreds of iterations to produce a competitive result. Recent works have proposed solutions that allow for faster generation with fewer iterations, but the image quality gradually deteriorates with increasingly fewer iterations being applied during generation. In this paper, we reveal some of the causes that affect the generation quality of diffusion models, especially when sampling with few iterations, and come up with a simple, yet effective, solution to mitigate them. We consider two opposite equations for the iterative denoising, the first predicts the applied noise, and the second predicts the image directly. Our solution takes the two options and learns to dynamically alternate between them through the denoising process. Our proposed solution is general and can be applied to any existing diffusion model. As we show, when applied to various SOTA architectures, our solution immediately improves their generation quality, with negligible added complexity and parameters. We experiment on multiple datasets and configurations and run an extensive ablation study to support these findings.
Pressure effect on the electronic, structural, and vibrational properties of layered <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mn>2</mml:mn><mml:mi>H</mml:mi><mml:mo>−</mml:mo><mml:msub><mml:mi>MoTe</mml:mi><mml:mn>2</mml:mn></mml:msub></mml:mrow></mml:math> (2019)

Layered molybdenum dichalchogenides differ from the classic example of bilayer graphene with their unique electronic properties: the application of pressure can continuously tune electronic structure since the band gap is controlled by delicate interlayer interaction. Here, we have performed measurements of Raman scattering, synchrotron x-ray diffraction, electrical conductivity, and Hall coefficient combined with density functional theory calculations to synthetically study the pressure effect on $2H\ensuremath{-}{\mathrm{MoTe}}_{2}$. Both the experiments and calculations consistently demonstrate that ${\mathrm{MoTe}}_{2}$ undergoes a semiconductor-to-metallic (S-M) transition above 10 GPa. Unlike ${\mathrm{MoS}}_{2}$, the S-M transition is driven by the gradual tunability of electric structure and band gap without structural transition. The applied pressure also effectively enhances conductivity and carrier concentration while reducing the mobility, which makes ${\mathrm{MoTe}}_{2}$ more suitable for applications than most other transition-metal dichalchogenides and allows it to be applied in strain-modulated optoelectronic devices.
Structure and Assembly of the Heterotrimeric and Homotrimeric C-Propeptides of Type I Collagen:  Significance of the α2(I) Chain (2005)

Assembly of the type I procollagen molecule begins with interactions among the C-pro alpha1(I) and C-pro alpha2(I) domains. The C-propeptide domains themselves have subdomains of distinct structures. The important questions are where chain association begins and the basis of the chain selectivity which leads to the preferential formation of the [C-pro alpha1(I)]2[C-pro alpha2(I)] heterotrimer. These questions are addressed by energy minimization modeling of the individual C-propeptide structures, study of their docking interactions, and comparison of the heterotrimeric and homotrimeric C-pro structures and stability. The comparisons show the remarkable impact of the C-pro alpha2 chain on the structure of the assembled trimeric C-propeptide. In the modeling, the three chains were anchored and registered by a short C-terminal collagen triple-helical segment followed by the C-telopeptides in their docked conformation, and then the remaining C-propeptide chains were allowed to interact and dock. Surprisingly, propeptide trimerization did not proceed through the previously proposed N-terminal "oligomerization domain" of the C-propeptide [McAlinden et al. (2003) J. Biol. Chem. 278, 42200] but rather in the most C-terminal domains of type I procollagen chains. Molecular dynamics showed heterotrimer assembly to begin with dimer formation between globular G2alpha2 and the G2alpha1(2) domains followed by trimerization at the G1 domains. Assembly initiation in the putative oligomerization coiled-coil domain is not possible because of the Pro residues at positions 3, 7, and 11 at the N-terminus of the alpha2 C-propeptide chain. To confirm the computations and proposed assembly pathway, the G2alpha1 and G2alpha2 domains were prepared recombinantly as the maltose binding protein constructs, and their interactions were studied by dynamic light scattering and gel filtration chromatography. Under the conditions examined MBP remained as monomer, MBP-G2alpha1 and MBP-G2alpha2 alone formed dimers, but a 2:1 mixture of MBP-G2alpha1 and MBP-G2alpha2 favored trimer formation. Thus, the C-terminal globular domains (G2) of the type I collagen C-propeptides play a crucial role in the initiation of intermolecular assembly and heterotrimer selectivity.

Coherent-State Quantum Process Tomography (2009)

The technologies of quantum information and quantum control are rapidly improving, but full exploitation of their capabilities requires complete characterization and assessment of processes that occur within quantum devices. We present a method for characterizing, with arbitrarily high accuracy, any quantum optical process. Our protocol recovers complete knowledge of the process by studying, via homodyne tomography, its effect on a set of coherent states, i.e. classical fields produced by common laser sources. We demonstrate the capability of our protocol by evaluating and experimentally verifying the effect of a test process on squeezed vacuum.

Skyrmion Echo in a system of interacting Skyrmions (2022)

We consider helical rotation of skyrmions confined in the potentials formed by nano-disks. Based on numerical and analytical calculations we propose the skyrmion echo phenomenon. The physical mechanism of the skyrmion echo formation is also proposed. Due to the distortion of the lattice, impurities, or pinning effect, confined skyrmions experience slightly different local fields, which leads to dephasing of the initial signal. The interaction between skyrmions also can contribute to the dephasing process. However, switching the magnetization direction in the nanodiscs (e.g. by spin transfer torque) also switches the helical rotation of the skyrmions from clockwise to anticlockwise (or vice-versa), and this restores the initial signal (which is the essence of skyrmion echo).
EXPERIMENTAL EVIDENCE FOR CHEMO-ELECTRONIC CONVERSION OF WATER ADSORPTION ON THE SURFACE OF NANOSIZED YTTRIA-STABILIZED ZIRCONIA (2017)

Direct energy conversion techniques are now dominated by photovoltaics.But, this dominance will be soon challenged by the emergence of a new conversion methods, known as so called "chemovoltaic".Here we demonstrate the possibility of the electric energy generation through interactions of atmospheric moisture and ZrO 2 based nano-powder systems.Such electric energy generation occurs by the conversion of the energy of exothermic heterophase electrochemical reaction.Creation of electromotive force is confirmed by electrical measurements of experimental specimens at a saturation flux density gradient of atmospheric moisture.

Institutional Factors in Economic Forecasts (2021)

The article assesses the possibilities of including institutional factors in macroeconomic and sectoral forecasts. It has been substantiated that a number of institutional features associated with the concentration of business in sectors of the economy and its consolidation around the leading group of companies in the market may reflect qualitative changes in the architecture of markets, the strengthening of explicit or implicit dominance, the formation of institutional barriers and traps. At the same time, the outstripping growth of large business significantly affects the industry dynamics and structural shifts, but is not synchronized across industries and is uneven in time. An approach is proposed for comparing the processes of business consolidation in the sectors of the Russian consumer market. Quantitative calculations have been performed, confirming the hypothesis of the importance of institutional factors that enhance the influence of large business in industries on the dynamics of their indicators. An assumption is made about a qualitative change in the sensitivity of markets to government regulation measures, depending on the stability of their architecture.
Abstract 2566: Blocking the functional domain of TIP1 upregulates midkine via the β-catenin/Wnt signaling pathway (2023)

Abstract Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortalities world-wide. Targeted therapy has been a growing topic of investigation to improve therapeutic efficacy for NSCLC. A few targeted therapies that exploit aberrant protein expression profiles have been approved for NSCLC. However, marginal improvement in efficacy observed with these therapeutic approaches highlights the need for discovery of additional therapeutic targets. Tax interacting protein 1 (TIP1) is a molecular target that is overexpressed on the surface of various cancers and correlates with poor overall patient survival. The functional domain of TIP1 (PDZ domain) caps the C-terminus of many cellular proteins that regulate cell signaling, cancer development, and progression. We found that antibodies against the PDZ domain of TIP1 induced cytotoxicity of lung cancer cells but not normal cells. A quantitative mass spectrometry-based approach identified a ten-fold increase in Midkine protein expression on blockade of TIP1. Midkine is a heparin-binding growth factor that is involved in cancer progression, therapy resistance, and immune suppression. This study tested the hypothesis that Midkine is upregulated by the anti-PDZ/TIP1 antibody via the β-catenin/Wnt signaling pathway, which subsequently modulates downstream signaling mechanisms. In co-immunoprecipitation studies we found a direct interaction of TIP1 with β-catenin on the cell surface. Anti-TIP1 antibody treatment led to nuclear translocation of β-catenin in NSCLC cells. We used a luciferase based TOPFlash/FOPFlash reporter assay to study the transcriptional activity of the canonical β-catenin/Wnt pathway following TIP1 blockade. Reporter assays showed a three to four-fold increase (p&amp;lt;0.0001) in the transcriptional activity of β-catenin following TIP1 blockade in NSCLC cells. Genetic silencing of β-catenin inhibited Midkine mRNA transcription (p&amp;lt;0.005), protein induction and its extracellular release (p&amp;lt;0.0001) following anti-TIP1 antibody treatment. In conclusion, the mechanism of Midkine release following TIP1 blockade involves the β-catenin/Wnt signaling pathway. Ongoing studies are evaluating the dual-targeting of TIP1 and Midkine for enhanced efficacy of NSCLC treatment. Citation Format: Minakshi Saikia, Abhay K. Singh, Nathan Cheung, Dennis E.

Bacteriophage Therapy and <i>Campylobacter</i> (2014)

This chapter discusses efforts to exploit Campylobacter-specific bacteriophages to reduce the numbers of C. jejuni and C. coli colonizing poultry and contaminating poultry meat products. All the phages reported by investigators in two studies had icosahedral heads and long contractile tails that were classified as members of the Myoviridae. Two phages with head diameters of 140.6 and 143.8 nm and large genome sizes of 320 kb were classified as group I. Five phages classified into group II had average head diameters of 99 nm and average genome sizes of 184 kb. A fourth phage had an icosahedral head that was classified as morphotype B1 of the Siphoviridae, while a fifth phage had an icosahedral head with a short tail of morphotype C1 in the Podoviridae. Campylobacter phages on the skin of retail chicken portions have been recovered at levels of 2 × 103 PFU/10 cm2 and this study found that Campylobacter phage could be isolated from chicken skin only when detectable levels of their host were also present. The spontaneous production of CampMu bacteriophages after bacteriophage therapy is of concern because Mu bacteriophages are potential agents of mutation. Attempts to utilize bacteriophage, initially for typing purposes and more recently for their biocontrol potential, have led to a greater awareness of the role that phage play in the complex ecology of Campylobacter. It should be noted that bacteriophage can shape the evolution of Campylobacter genomes as they do in other bacterial genera.
Abstract 2124: Accuracy of T2-weighted Cardiac Magnetic Resonance in Detecting Myocardial Edema in Acute Myocardial Infarction is Strongly Influenced by Microvascular Obstruction. (2007)

Background: High signal intensity (SI) on T2-weighted Cardiac Magnetic Resonance (CMR) indicates infarct-associated myocardial edema in patients with acute myocardial infarction (MI). However, erythrocytes leaking from capillaries in infarct tissue may result in reduced signal on T2W CMR due to T2 shortening. The purpose of this study was to determine if detection of myocardial edema with T2-weighted CMR is influenced by microvascular obstruction (MO- ). Methods: Thirty-seven patients underwent black blood T2 weighted MRI with a spectral presaturation with inversion recovery fat saturation method, rest perfusion MRI and late gadolinium enhanced (LGE) MRI 5.4±3.1 days after onsets. The presence and transmural extent of LGE and MO were analyzed based on a 16-segment model. The relative SI compared with remote normal myocardium was determined in the infarction and peri-infarction zones on T2 weighted MRI, by using the mean + 2SD of the SI in normal segments as a threshold. Results: LGE was observed in 37 (100%) of 37 patients and MO in 19 (51%) of 37 patients. The SI in LGE segments without MO and the SI in periinfarct zones were significantly higher than those in normal segments (relative SI 1.84±0.5, p&lt;0.001 and 1.69±0.18, p&lt;0.001, respectively). However, no significant difference was found between the SI in MO segments and the SI in normal segments (relative SI 1.12±0.24, p=N.S.). The sensitivity of T2 weighted MRI for detecting edema in acute MI was 95% (73/77) in the LGE segments without MO, but was reduced to 30% (22/73) in the segments with MO. Myocardial edema was completely missed on T2 weighted MRI in 2 patients with severe MO. Conclusions: Although T2-weighted CMR is highly sensitive in detecting myocardial edema in the segments without MO, reduced T2 signal intensity in MO segments can be an important pitfall in characterizing the area of the acute event.
&lt;title&gt;Assembly and interconnection technologies for electrical and optical microsystems&lt;/title&gt; (1996)

Silicon micromachining, thin-film-multilayer-technology, integrated optical circuits and micro-optics were combined to realize optoelectronic microsystems. The potential of silica based inorganic waveguide materials and optical polymers were investigated and compared with respect to their process compatibility and their ability for integration with electronic, optoelectronic and micromechanical functions. An integrated optical modulator, an optical 2 by 2-switch and a micro-optical receiver were realized as test devices. The results reveal advantages of polymeric materials with respect to the optical functions of modulating or switching of light on the basis of thermo- optical phase shifting. However, the integration of the various process steps into a complete microsystem could only be accomplished with silica based optical circuits.
Relationship between phase-conjugation efficiency and grating response time in semiconductor-doped glasses (1989)

It is shown experimentally that deviations from the square dependence of the phase-conjugate reflectivity in CdSxSe1−x-doped glasses on the reduced pump power can be explained by the dependence of the relaxation time of the induced optical nonlinearity on intensity. The same argument explains the diversity of several previously published results.
Investigation of ultrasonic, dielectric and piezoelectric properties of the xLMT - (1-x)BT ceramics with x=0.025, 0.05, 0.075, 0.1 (2007)

Ultrasonic, dielectric and piezoelectric studies of lead free ceramic system structures of (1-x) BaTiO3-xLa(Mg1/2Ti1/2)O3 (BT-LMT) are presented in this contribution. It was shown, that such materials with x=0.025, 0.05, 0.075 and 0.1 LMT content undergo phase transitions and exhibit piezoelectric effect in the low temperature phases. Anomalies of ultrasonic velocity and attenuation at phase transitions have been observed in these materials. Measurements of temperature dependencies of ultrasonic velocity and attenuation revealed anomalies related to phase transitions in these materials. It was shown that, at room temperature and under DC bias electric field, these ceramics behave as a piezoelectrics because of electrostriction.
Virtual reality simulation modeling for a haptic glove (2003)

The recent addition of force and touch feedback to virtual reality simulations has enhanced their realism. Research on haptics interfaces is now extended to physical modeling of contact surfaces, object hardness, surface deformation, etc. This is especially needed when dextrous manipulation of virtual objects is concerned. The paper describes a VR system using a haptic glove (Rutgels Master II) connected to a PC workstation, and a new method for modeling virtual hand haptic interactions. An application example presented here is an orthopedic rehabilitation library. The exercises in this library involve interactions with dynamic objects and physical modeling of plasticity.
