A DFE-Enhanced Phase-Difference Modulation Signaling for Multi-Drop Memory Interfaces

This brief presents a phase-difference modulation signaling enhanced by decision feedback equalization for multi-drop memory interfaces. The phase-difference modulation signaling enables efficient data communication via a multi-drop channel, but only if the stub lengths are specially engineered. In this brief, the phase-difference modulation signaling is combined with decision feedback equalization to extend the applicable channel range. A test chip with a phase-difference-modulation transmitter and a decision feedback equalization receiver was fabricated in 65-nm CMOS technology. With a 2-tap decision feedback equalization, the test chip achieved the data rate of 7.8 Gb/s/pin via the both multi-drop channels with a long 10-cm stub and a short 2-cm stub, whereas the previous work without decision feedback equalization does not work with the 2-cm stub channel at 7.8Gb/s/pin.
Comparison of saturation current characteristics for ultrathin silicon oxides grown on n- and p-type silicon substrates simultaneously

Rapid thermal oxidations were simultaneously performed on n- and p-type silicon substrates to investigate the saturation currents of metal-oxide-semiconductor (MOS) capacitors. For MOS capacitors on n-type Si substrates, the curves of capacitance versus gate voltage (C-V) show almost no fixed charge, no lateral nonuniformity, and little interface trap density (Dit). The mechanism of the generation of the saturation current is recombination, and was investigated by electroluminescence. Also, the saturation current decreases as the oxide becomes thicker. However, the oxidation temperature must be sufficiently high to form high-quality oxide on p-type Si substrate. Controlled by minority carrier generation, the saturation current of the MOS (p) capacitor also depends on Dit, suboxide, and bulk trap density. The saturation current increases with the thickness of the oxide. The generation mechanism of the saturation currents of MOS (p) capacitors was also investigated by observing their dependencies on tempera.
Repenser l’expérience d’enseignement et d’apprentissage en situation de confinement pédagogique

In a period of lockdown, many establishments have chosen educational continuity. As a result, teachers had to revise their teachings in a very short time in order to offer relevant learning activities to the students. In this practical paper, we present what we have put in place for the course History and technology of everyday objects offered to future engineers from the University of Technology of Troyes (France). The use of technology has had certain advantages as well as limitations that we present in order to reproduce and adapt the lived experience.
The Velocity of Corrosion from the Electrochemical Standpoint

It is now agreed that the wet corrosion of metals is usually an electrochemical process, accompanied by the flow of electric currents over measurable distances. Direct combination, without appreciable flow of current, is indeed met with in some cases, for instance, in corrosion by a solution of a halogen. But direct attack by dissolved oxygen would lead to the production of a film of oxide, which, being sparingly soluble, would restrain further action. Indirect electrochemical action by oxygen, in the presence of a salt, will, however, often yield soluble bodies as the primary products; thus iron in sodium chloride solution containing oxygen, fields ferrous chloride at the anodic areas and sodium hydroxide at the cathodic areas. Where these primary products meet, in presence of oxygen, they yields a mixture of hydrated iron oxides known as "rust"; but such secondary products—although almost insoluble— are usually precipitated at a sensible distance from the metal, and do not protect it from further attack. In cases where electrochemical action would lead to a sparingly soluble salt as the direct product, the attack does not develop; thus lead, although rapidly attacked by a nitrate solution in presence of oxygen, is hardly affected by a sulphate solution. The electric currents involved in the corrosion-process may be set up:— ( a ) By differences in the metallic object ( e. g ., on a "bimetallic" specimen, where one metal serves as cathode and the other as anode; or on iron partly covered with mill-scale, which serves as cathode, the exposed metal acting as anode).
Androgen deprivation therapy and the risk of subsequent keratitis

Objectives: The objective of the study was to determine the risk of subsequent keratitis in prostate cancer (PCa) patients treated with androgen deprivation therapy (ADT). Materials and Methods: Three thousand three hundred and nine patients with PCa were identified using data from Taiwan’s National Health Insurance Research Database for 2001 through 2013. Among those patients, 856 treated with ADT comprised the study group, while 856 non-ADT-treated patients matched with 1:1 propensity-score-matched analysis comprised the control group. The demographic characteristics and comorbidities of all the patients were analyzed, and Cox proportional hazards regression was utilized to determine the hazard ratios (HRs) for subsequent keratitis. Results: A total of 157 (9.2%) patients had newly diagnosed keratitis. Compared to the non-ADT-treated patients, the ADT-treated patients had a reduced risk of subsequent keratitis, with an adjusted HR of 0.38 (95% confidence interval: 0.27–0.55; P < 0.001). Conclusion: ADT treatment apparently decreased the risk of subsequent keratitis in the investigated PCa patients, but the clinical significance of this finding should be further assessed in additional studies.
Electrochemistry and Morphology Evolution of Carbon Micro-net Films for Rechargeable Lithium Ion Batteries

The highly ordered carbon micro-net films (CMNFs) have been fabricated through patterning and pyrolyzing SU-8 photoresist. They are structurally characterized by transmission electron microscopy and selected area electron diffraction, and they exhibit the mixed phases of both crystalline and disordered carbon. An initial discharge capacity of as large as 350 μAh/cm2 is observed, and the pseudocapacitance-like charge/discharge curves with reversible capacity of about 100 μAh/cm2 are shown in the following cycles. From the images of scanning electron microscopy, the originally three-dimensional architecture of CMNFs is well kept after long-term electrochemical cycling. The kinetic parameters such as solid electrolyte interphase resistance, charge transfer resistance, and chemical diffusion coefficients of Li+ insertion are estimated by alternate-current impedance measurements. The CMNFs are expected to be promising electrodes for future three-dimensional microbatteries.
Climate change, vulnerability and securitization

This article aims to examine whether vulnerability to Global Climate Change (GCC) increases or decreases a country’s attempts to securitize the issue. The research was based on the hypothesis that the more vulnerable the country to GCC, the more likely it is for the government to securitize its agenda. Seven countries were analyzed according to the Notre Dame Global Adaptation Initiative (ND-GAIN), the climate vulnerability index. The conclusion is that the hypothesis does not stand, and new guidelines for further research were suggested.
Inflammation, Delirium, Dementia and Ageing Brain Phenotypes: A Short Review and the Need for New Approaches to Explore Immune System Complexity

Ageing is associated with persisting systemic inflammation, both in chronic form and as delayed resolution after acute inflammatory illnesses. The clearest markers of this are raised blood concentrations of pro-inflammatory cytokines and other chemokines that are involved in mediating an inflammatory state, and C-reactive protein as general indicator of inflammation. This condition of “inflammaging” is linked causally in a complex and reciprocal manner with several diseases that are prevalent in older people including a tendency to develop delirium during acute perturbations of brain function, and to a predisposition to dementia and other age-associated neurodegenerative conditions. There is evidence of a key role of cytokines both in the aetiologies of such diseases and in the immune modulation processes that reduce inflammation, and evidence that interleukin-6 has a particularly complex effect depending on physiological and metabolic context. It is probable that the influence of cytokines on the central nervous system is directly mediated via receptors on neurons, microglial cells and astrocytes, rather than through secondary metabolic effects. The epigenetic mechanisms involved are starting to be understood. Though the descriptive phenomenology of inflammation has produced a large amount of information it is obviously, like the biochemistry of all living organisms, an extremely complex environment that cannot be described adequately using linear pathways, or even 3-dimensional models. To deal with the complexity, fluidity, stability, responses and fluctuations of immune chemistry it is proposed that a better grasp of immune system regulation, its responses to perturbation and its relationship with disease states and aging, including neuropathology, might be better progressed by using a multifactorial conditional logic approach, such as Boolean analysis. Such work will require an iterative collaboration between clinicians, molecular biologists, mathematicians and software engineers.
Milestones And Challenges In Skin Cancer Carcinogenesis

The skin represents one of the largest organ systems of the human body – constituting about onetwelfth of our total body weight. Positioned as the interface between the internal systems of the body and its environment, the skin acts as a barrier to an expansive array of extrinsic agents and provides the foremost target for environmental insult [1]. Thus, it is not surprising that skin cancer, in some light-skinned populations, such as Australia, United Kingdom, and the United States represents the most frequently occurring neoplastic disease. In fact, a descriptive analysis of populationbased fees-for-service physicians’ claims and National Ambulatory Medical Care service database found that the total number of procedures increased by 76.9% from 1,158,298 in 1992 to 2,048, 517 in 2006. Further, the total number of NonMelanoma Skin Cancers (NMSC) in the U.S. population in 2006 was estimated at 3,507,693 and total number of persons in the U.S. treated for NMSC estimated at 2,152,500 [2]. NMSC is the most frequently occurring cancer with an estimated 5.4 million new cases each yearmore than all other types of cancers combined [3].
Theoretical Approach to the Stability of Visbroken Residues

A theoretical method to calculate solubility parameter distributions was used to study the main factors that affect the stability of residues and products of their visbreaking with respect to asphaltene deposition. With this method it was possible to analyze the changes observed on the solubility parameter distributions of asphaltenes due to visbreaking. The results obtained showed a decrease in easily soluble asphaltenes, while there is an increase in difficult-to-dissolve asphaltenes during processing. To evaluate the instability, a compatibility index between asphaltenes and resins/or aromatics is proposed using the theoretical solubility profiles. By use of this index, it was possible to identify the factors involved in instability and to establish their relative importance for each sample. Among all the factors studied, the characteristics of the asphaltene fraction seem to be the main one. For the group of fractions examined, it was found that the average solubility parameter calculated was directly.

This article is in three parts. In the first part, the first author documents operational details of a proven method of successfully meeting, and exceeding, the expectations of the stakeholders in the tertiary education sector. In addition, the first author discusses more efficient and effective ways of writing meaningful assessments, marking and moderating, than the ones in current use in many New Zealand tertiary institutions.
Correlation Between Periodicity and Catalytic Growth Activity of Bimetallic Co-group VI/MgO Catalysts for Production of Carbon Nanotubes by Acetylene Using Chemical Vapor Deposition

This work aims to discover a relationship between the periodicity and catalytic growth activity of carbon nanotubes by acetylene chemical vapor deposition. Hence, the effect of addition of group VI metals (25% of Cr, Mo, or W) of the periodic table to 25 wt% Co supported on MgO has been investigated. The fresh catalysts and carbon nanomaterials were characterized by XRD, TPR, TEM, Raman spectroscopy, BET surface measurements, and TG analysis. The results revealed that the addition of group VI metals induces a strong interaction with the structural MgO crystals associated with an enhancement in surface properties. XRD data shows that the appearance of group VI metal oxides in the diffraction patterns primarily dependent on the corresponding atomic weights. TGA data shows that the Co–W/MgO catalyst exhibited higher carbon nanotubes (CNTs) yield compared to the Co–Cr or Co–Mo containing catalysts. The yield of CNTs increases gradually with increasing the atomic weight of group VI metals (W > Mo > Cr). This finding can be attributed to the higher surface coverage of Co-W/MgO and consequently the larger amount of metal sites which are responsible for the higher yield of MWCNTs compared to the other bimetallic catalysts. The higher metallic surface permits decomposing a larger amount of C2H2 molecules more efficiently. XRD, TEM, and Raman spectroscopic data revealed that highly graphitized MWCNTs were produced over all catalysts under study.
Systematic Beam Management in mmWave Networks: Tradeoff Among Beam Coverage, Link Budget, and Interference Control

In this paper, we study the beam management problem in mmWave networks from a systematic perspective. Instead of maximizing the network performance in terms of user sum-rate, we improve the beam coverage, which could potentially reduce beam tracking overhead for mobile users. Moreover, to compensate the severe signal attenuation in mmWave bands, we configure the beam to meet the user link budget requirement. To reduce the interference among users, we take the inter-beam interference from both main-lobe and side-lobe into consideration. Overall, we formulate our beam management scheme as a non-linear integer optimization problem. By deliberately transforming it to a geometric optimization problem and designing a rounding method, we develop a suboptimal solution, with low computational complexity. Based on this, we further design a scheduling user set refining method, which can assist user scheduling in the MAC layer, to make the beam configuration request within the antenna capability. Extensive simulation results demonstrate that our proposed algorithm could manage the beam on-line, while satisfying beam configuration requests for beam coverage, link budget, and inter-beam interference control.
Multiobjective Optimization and Data-Driven Constraint Adaptive Predictive Control for Efficient and Stable Operation of PEMFC System

Efficient and stable operation (ESO) of the proton exchange membrane fuel cell (PEMFC) system is challenging because the nonlinearity of system not only aggravates the difficulty of performance analysis but also puts forward higher requirements for controller design. In this article, a hierarchical performance enhancement control strategy (HPECS) is proposed, which can deal with optimal trajectory seeking under multiobjective constraints and nonlinear problem of system separately. In upper optimization level, the multiobjective optimization based on dynamic adjustment of weighting factor is proposed to seek optimal trajectory for ESO of PEMFC system considering the harm of oxygen starvation, oxygen saturation to system, and contradiction characteristic between net power and efficiency; in lower control level, a data-driven constraint adaptive predictive control is proposed for optimal trajectory tracking with the nonlinearity of system. The proposed HPECS is implemented and validated on the experimental PEMFC system. The comparative studies show that the proposed HPECS is superior in performance enhancement, disturbance rejection, and tracking ability. The normalized multiobjective optimization function can be basically guaranteed to above 0.9, and a nearly 7.2% enhancement in average can be also observed, which shows that ESO of PEMFC system can be achieved in changeable working conditions under proposed HPECS.
In-Depth Investigation of Biomass Pyrolysis Based on Three Major Components: Hemicellulose, Cellulose and Lignin

To better understand biomass pyrolysis, the different roles of the three components (hemicellulose, cellulose, and lignin) in pyrolysis are investigated in depth using a thermogravimetric analyzer (TGA). The pyrolysis characteristics of the three components are first analyzed, and the process of biomass pyrolysis is divided into four ranges according to the temperatures specified by individual components. Second, synthesized biomass samples containing two or three of the biomass components are developed on the basis of a simplex-lattice approach. The pyrolysis of the synthesized samples indicates negligible interaction among the three components and a linear relationship occurring between the weight loss and proportion of hemicellulose (or cellulose) and residues at the specified temperature ranges. Finally, two sets of multiple linear-regression equations are established for predicting the component proportions in a biomass and the weight loss of a biomass during pyrolysis in TGA, respectively. The resul.
Synthesis of high quality 2D carbide MXene flakes using a highly purified MAX precursor for ink applications

The practical application of 2D MXenes in electronic and energy fields has been hindered by the severe variation in the quality of MXene products depending on the parent MAX phases, manufacturing techniques, and preparation parameters. In particular, their synthesis has been impeded by the lack of studies reporting the synthesis of high-quality parent MAX phases. In addition, controllable and uniform deposition of 2D MXenes on various large-scale substrates is urgently required to use them practically. Herein, a method of pelletizing raw materials could synthesize a stoichiometric Ti3AlC2 MAX phase with high yield and processability, and fewer impurities. The Ti3AlC2 could be exfoliated into 1–2-atom-thick 2D Ti3C2Tx flakes, and their applicability was confirmed by the deposition and additional alignment of the 2D flakes with tunable thickness and electrical properties. Moreover, a practical MXene ink was fabricated with rheological characterization. MXene ink exhibited much better thickness uniformity while retaining excellent electrical performances (e.g., sheet resistance, electromagnetic interference shielding ability) as those of a film produced by vacuum filtration. The direct functional integration of MXenes on various substrates is expected to initiate new and unexpected MXene-based applications.
Bovine pancreatic trypsin inhibitor crystals with different morphologies: a molecular dynamics simulation study

A molecular dynamics simulation study is reported for three polymorphic protein crystals (4PTI, 5PTI and 6PTI) of bovine pancreatic trypsin inhibitor (BPTI). The simulated lattice constants are in good agreement with experimental data, indicating the reliability of force field used. The fluctuation patterns of peptide chains in the three crystals are similar, and the protein structures are fairly well maintained during simulation. We observe that water forms a pronounced hydration layer near the protein surface. The diffusion coefficients of water in the three crystals are smaller than in bulk phase, and thus, the activation energies are higher. The porosity, fluctuation of peptide chains and solvent-accessible surface area as well as the diffusion coefficients of water and counterion in 5PTI are the largest among the three crystals. The diffusion of water and counterion is anisotropic, and the degree of anisotropy increases in the order of 4PTI < 5PTI < 6PTI. Despite a slight difference, the structural and diffusion properties in the three BPTI crystals are generally close. This simulation study reveals that crystal polymorphism does not significantly affect microscopic properties in the BPTI crystals with different morphologies.

This paper is prepared as a contribution to the UNU-WIDER Project on “Transforming Informal Work and Livelihoods”. The paper is divided into three main sections: what we mean by informality and work status; why we should differentiate between work statuses; and what we can learn by analyzing work statuses and transitions between them. I gratefully acknowledge invaluable comments and discussions with Tim Gindling and Kunal Sen on earlier drafts.
Preparation and Properties of Novel Poly(urethane-imide)s via Blending of Reactive Polyimide and Epoxy-Terminated Urethane Prepolymers

Polyurethane networks with enhanced thermal stability and electrical insulation properties were prepared from the reaction of epoxy-terminated urethane prepolymers (EPU) and polyimides containing pendant phenol groups (HPI). EPUs were prepared by the reaction of glycidol with NCO-terminated urethane oligomers. The oligomers were prepared from different molecular weight versions of polycaprolactone polyol (CAPA) and hexamethylene diisocyanate. The progress of the reaction was monitored by differential scanning calorimetric analysis in the presence and absence of suitable catalyst. The onset temperature of exothermic reaction of phenolic groups and epoxy rings was chosen as optimum curing temperature and the reaction duration was optimized by gel content measurement. The starting materials and polymers were characterized by conventional spectroscopic methods, and physical, thermal and electrical properties of the crosslinked networks were determined. The novel poly(urethane-imide)s exhibited considerable improvement in thermal and electrical properties in comparison to common polyurethanes.
