Value first, then price: the new paradigm of B2B buying and selling
Authors: Hinterhuber Andreas , Snelgrove Todd C. , Stensson Bo-Inge 
Published: March 2021

AbstractMost companies today take an inherently adversarial approach to buying and selling in industrial markets, thereby missing out on opportunities for joint value creation with customers and suppliers. Sales as well as procurement are too obsessed with price and not enough with value. In this paper we present a set of principles that put joint value creation at the centre of the relationship with customers and suppliers. With respect to customers, the value quantification capability is the most important competency of the sales function, i.e. the ability to translate a firm’s competitive advantages into one quantified, monetary value reflecting both qualitative as well as quantitative customer benefits. With respect to suppliers, we call for the creation of new metrics, such as total value of ownership, reflecting innovation, management capabilities, sustainability, and other elements beyond quality, price, and delivery. With value quantification capabilities (sales) and total value of ownership models (procurement) the key element of relationship with both customers and suppliers is value first, then price.

Published: March 2021

SignificanceExpression of keratin 17 (K17), an intermediate filament-forming cytoskeletal protein, is induced in a broad range of human carcinomas and has prognostic value for a growing number of tumor types. We report here that K17 is induced in response to DNA damage and that a nuclear pool of K17 regulates the immediate response to such damage, with an associated impact on cell survival. Impairing the nuclear pool of K17 markedly attenuates tumor initiation in mouse skin. Our finding adds a role for nuclear K17 in the DNA damage response (DDR) and further substantiates the significance of K17 expression and function during tumorigenesis.
“Would it be fair to say that you actively sought out material?”
Authors: de Pablos-Ortega Carlos 
Published: March 2021

Abstract
The aim of investigative interviews is to gather comprehensive and reliable information from suspects, offenders,
victims and witnesses through questioning. Research on questioning during police interviews has mainly explored question types and
question approaches when interviewing adults and children. This chapter is concerned with so far unexplored aspects of police
interviewing, that is the employment of mitigating and aggravating linguistic devices in questions and statements and their
pragmatic effects. The corpus consists of six police interviews with suspects of crime. Mitigation and aggravation strategies were
extracted and a total of eighty-two instances were found, analysed and classified into a categorisation taxonomy which was
designed to ascertain the types and functions of mitigation and aggravation devices. The findings reveal that more mitigation than
aggravation strategies were used in police questioning and statements during the interviews. Mitigation was found to be used not
only as a device for alleviating or attenuating, but also as a strategy to build rapport between suspects and police officers.
Translating accurately or sounding natural?
Authors: Hijazo-Gascón Alberto 
Published: March 2021

Abstract
Police interview interpreting is a complex task, as interpreters make difficult choices under pressure and time
constraints. The main dilemma of the interpreter is whether to remain faithful to the original text, with the risk of rendering
non-idiomatic translations, or to give preference to more idiomatic versions that may entail an addition or an omission from the
original text. This article presents an analysis of Spanish-English bilingual police interviews in California. The analysis is
based on the discrepancies found between an interpreter present in the interrogation and a control interpreter who translates the
whole interview post-hoc. This is an original methodology that can be used for future research in this and other contexts. The
results show different types of inaccuracies in the interpretation, which can be attributed to contextual pressures and overall
challenges of interpreting and to challenges related to typological differences between the two languages involved.
Balancing Need and Risk, Supply and Demand: Developing a Tool to Prioritize Naloxone Distribution

Published: March 2021

Background Opioid overdose deaths continue to rise nationally. The demand for naloxone, the opioid overdose antidote, is outpacing the supply. With increasing naloxone requests, tools to prioritize distribution are critical to ensure available supplies will reach those at highest risk of overdose. Methods We developed a standardized “Naloxone Request Form” (NRF) and corresponding weighted prioritization algorithm to serve as decisional aid to better enable grant staff to prioritize naloxone distribution in a data-driven manner. The algorithm computed raw priority scores for each agency, which were then separated into the predetermined quintiles. Historical naloxone distribution decisions were compared with agencies’ prioritization quintile. Results Results demonstrated that the NRF and corresponding algorithm was successful at prioritizing agencies based on potential impact. Although, overall, naloxone was distributed more heavily to the agencies deemed highest priority, our algorithm identified significant shortcomings of the “first come, first served” method of distribution we had initially deployed. Conclusions This work has laid the foundation to use this tool prospectively to allow for data-driven decision-making for naloxone distribution. Our tool is flexible and can be customized to best fit the needs of a variety of programs and locations to ensure the distribution of limited supplies of naloxone have the greatest impact.
Lensing contribution to the 21 cm intensity bispectrum
Authors: Kothari Rahul , Maartens Roy 
Published: March 2021

Abstract
Intensity maps of the 21 cm emission line of neutral hydrogen are lensed by intervening large-scale structure, similar to the lensing of the cosmic microwave background temperature map. We extend previous work by calculating the lensing contribution to the full-sky 21 cm bispectrum in redshift space. The lensing contribution tends to peak when equal-redshift fluctuations are lensed by a lower redshift fluctuation. At high redshift, lensing effects can become comparable to the contributions from density and redshift-space distortions.
A model reference adaptive system approach for nonlinear online parameter identification
Authors: Kaltenbacher Barbara , Ngoc Nguyen Tram Thi 
Published: March 2021

AbstractDynamical systems, for instance in model predictive control, often contain unknown parameters, which must be determined during system operation. Online, or on-the-fly, parameter identification methods are therefore necessary. The challenge of online methods is that one must continuously estimate parameters as experimental data becomes available. The existing techniques in the context of time-dependent partial differential equations exclude the case where the system depends nonlinearly on the parameters. Based on a model reference adaptive system approach, we present an online parameter identification method for nonlinear infinite-dimensional evolutionary systems.
On-chip micro pressure sensor for microfluidic pressure monitoring
Authors: Zhang Renchang , Li Qian , Tian Lu , Gong Jiahao , Li Zhengming , Liu Wei , Gui Lin 
Published: March 2021

Abstract
In this work, a novel on-chip micro pressure sensor was developed for microfluidic pressure monitoring. Polydimethylsiloxane (PDMS) microfluidic chip contained a working fluid channel with a sealed detection channel beneath it. Any change in pressure in the working fluid channel would change the volume of the detection channel. A mixture of two immiscible fluids was sealed in the detection channel. The pressure of the working fluid can be monitored by measuring the interface displacement of the two fluids in the detection channel. A PDMS film between the working channel and detection channel can avoid cross-contamination between fluids. We acquired a calibration curve of the pressure sensor for measurement and optimized the performance of the sensor through parametric studies. Moreover, two pressure sensors were integrated into a microchip to characterize the pressure drop in the microchannel. The developed pressure sensor is inexpensive and easy to be integrated into microfluidic devices to monitor the flow conditions for cell culture, fluid mixing, and droplet manipulation.
Binary copper oxides as photovoltaic absorbers: recent progress in materials and applications
Authors: Wang Y , Pierson J F 
Published: March 2021

Abstract
Binary copper oxides are a promising class of p-type semiconductors for solar energy conversion applications due to their particular electrical and optical properties, elemental abundance, and non-toxicity. So far, three phases with different copper ion oxidation states, including cuprous Cu2O, paramelaconite Cu4O3, and cupric CuO, have already been successfully synthesized by thin-film deposition techniques. This work reviews recent progress in determining the physical properties of these three phases from the viewpoints of both experimental and theoretical calculations, including their thermodynamics, structure, microstructure, band structure, defects, and their optical and electrical properties. In particular, we discuss some undecided issues regarding the properties of these materials. In addition, we summarize recent advances in photovoltaic cells using copper oxides as absorbers, including correlations between device performance and material properties.
Vanadium dioxide embedded frequency reconfigurable metasurface for multi-dimensional multiplexing of terahertz communication
Authors: Wang Ling , Yang Yang , Deng Li , Hong Weijun , Zhang Chen , Li Shufang 
Published: March 2021

Abstract
Multi-dimensional multiplexing based on the broadband metasurface is a promising candidate for the next generation terahertz (THz) communication system, which has become a research focus for data transmission rate and channel capacity enhancement. This paper proposes a THz frequency-reconfigurable metasurface hybridized with vanadium dioxide (VO2) for communication multiplexing on both dimensions of orbital angular momentum and frequency. Theoretically, 4 × n channel (n can be any positive integer) orthogonal coaxial beams carrying different data flow can be simultaneously generated based on the proposed metasurface in the tunable operating frequency band. The simulation results verify that the THz incident waves can be converted into orthogonal coaxial beams with different topological charges or frequencies, propagating perpendicular to the metasurface, when eight-channel oblique incident plane waves with varying angles or at various frequencies are reflected by the metasurface. The multi-dimensional multiplexing can be achieved in the frequency range of 0.29–0.39 THz and 0.24–0.34 THz with the VO2 switching between its fully insulating and metallic state. The proposed metasurface is expected to enable multi-band and broadband applications and has significant potential in high-speed and high-capacity THz communication.
Gas sensing near exceptional points

Published: March 2021

Abstract
Here we investigate the possibility of gas sensing with ultrahigh sensitivity by exploiting the exceptional point (EP) in a non-Hermitian system. The underlying mechanism is that the transverse displacement induced by the photonic spin Hall effect (PSHE), which is significantly enhanced near EPs, is ultra-sensitive to the variation of refractive index in gas media. With the application of the weak measurement technique, we find that the sensitivity of the gas sensing can reach

Abstract
The general steps for the fabrication of a copper prototype of 325 MHz coaxial half-wave resonator (HWR) with β = 0.21 are presented and discussed in this work. The main features for the control of the electromagnetic properties during the manufacturing process of HWR are described in detail. The resonant frequency sensitivity to the accelerating gap and to the cavity height were experimentally estimated. Bead-pull measurements were performed and the electric field distribution along the beam axis of the manufactured cavity was estimated. The features of the cavity’s response in the critical coupling regime are analyzed. The experimental concept of a slow frequency tuning system (FTS) based on the moving plungers is proposed and tested. The tuning sensibility is experimentally estimated. The measured results agree with the simulations quite well, and the sensitivity for a single plunger configuration

Multiple pseudo-plateaux states and antiferromagnetic pair selection in the XY model in the highly frustrated honeycomb lattice
Authors: Gómez Albarracín F A , Rosales H D 
Published: March 2021

Abstract
We present a study of the low temperature magnetic phases of the classical XY model with third nearest neighbor interactions on the honeycomb lattice at the maximally frustrated point under an external magnetic field by extensive Monte Carlo simulations. We focus on the characterization of the emergent low temperature phases, which are a direct consequence of the unusually high numbers of spins per plaquette in the model. Specifically, we show that, since thermal fluctuations partially lift the ground-state degeneracy and select the most collinear states, the selected states are those with the highest number of ‘antiferromagnetic pairs’ (AFp) compatible with the external magnetic field. These AFp are formed in such a way that they maximize the degeneracy of the selected submanifold of ground states. Moreover, two collinear pseudoplateaux emerge at M = 1/3 and M = 2/3. To characterize the magnetization process, we employ Monte Carlo simulations and calculate relevant order parameters to construct the complete temperature vs magnetic field phase diagram.
A simple method to calculate solution-phase free energies of charged species in computational electrocatalysis
Authors: Granda-Marulanda Laura P , McCrum Ian T , Koper Marc T M 
Published: March 2021

Abstract
Determining the adsorption potential of adsorbed ions in the field of computational electrocatalysis is of great interest to study their interaction with the electrode material and the solvent, and to map out surface phase diagrams and reaction pathways. Calculating the adsorption potentials of ions with density functional theory and comparing across various ions requires an accurate reference energy of the ion in solution and electrons at the same electrochemical scale. Here we highlight a previously used method for determining the reference free energy of solution phase ions using a simple electrochemical thermodynamic cycle, which allows this free energy to be calculated from that of a neutral gas-phase or solid species and an experimentally measured equilibrium potential, avoiding the need to model solvent around the solution phase ion in the electronic structure calculations. While this method is not new, we describe its use and utility in detail and show that this same method can be used to find the free energy of any ion from any reaction, as long as the half-cell equilibrium potential is known, even for reactions that do not transfer the same number of protons and electrons. To illustrate its usability, we compare the adsorption potentials obtained with DFT of I*, Br*, Cl*, and SO4
* on Pt(111) and Au(111) and OH* and Ag* on Pt(111) with those measured experimentally and find that this simple and computationally affordable method reproduces the experimental trends.
Novel electric field effects on magneto-optical conductivity in eight-Pmmn borophene
Authors: Li Jing , Sun Yanmei , Wu Meimei , Pan Hui 
Published: March 2021

Abstract
We theoretically study the Landau levels and the magneto-optical conductivity of eight-Pmmn borophene in the presence of a perpendicular magnetic field and an inplane electric field. We find that in the absence of the inplane electric field, the magneto-optical conductivity of eight-Pmmn borophene presents a series of striking single resonance peaks as functions of the frequency ω, and the longitudinal conductivities are found to be anisotropic due to its anisotropic tilted Dirac cones. In the presence of the inplane electric field, some novel effects are predicted on the Landau levels and the magneto-optical conductivity. The Landau level spacings in the two tilted Dirac cones are different, which lifts the degeneracy of the twofold valley, and the magneto-optical conductivity appears a double peak structure. We also discuss the influence of the chemical potential between different Landau levels on the double peak of the magneto-optical response. The valley related magneto-optical properties in the anisotropic structure may make eight-Pmmn borophene a candidate for the new optical devices.
Rehabilitation of the former nuclear test site at Maralinga
Authors: Long Stephen , Cook Megan , Charalambous Fiona , Carpenter Julia 
Published: March 2021

Abstract
Large areas of the former British nuclear test site at Maralinga were contaminated by the explosive dispersal of plutonium. The Australian Government, in consultation with stakeholders, determined that the site should be cleaned-up so that it is fit for unrestricted habitation by the Aboriginal traditional owners (Maralinga Tjarutja). Engagement with the stakeholders, particularly the Maralinga Tjarutja, determined that the specific criterion for rehabilitation was 5 mSv y−1 and that some restrictions on permanent occupancy should remain. Remediation of the site began in 1995, took 5 years and cost AU$106 million. The site was returned to its traditional owners in 2009 and is now the site of a flourishing tourism operation.
A signal quality analysis method for electrocardiosignals in the CS domain
Authors: Liu Jizhong , Xu Wenbin , Zhao Peng , Hua Jing 
Published: March 2021

Abstract
Compressed sensing (CS) is an important cutting-edge low-power technology for wearable health monitoring systems. To solve the problem of how the quality of compressive sampled electrocardiosignal (ECG) affects the subsequent arrhythmia recognition and signal reconstruction, a novel ECG quality evaluation method in the CS domain is proposed. In order to achieve the evaluation effect in the CS domain, a modified bandpass filter method is designed to obtain the approximate frequency band energy and approximate wavelet entropy, which are used as the evaluation index for the support vector machine classifier to realize the CS ECG signal quality evaluation. Based on the simulation results from the MIT-BIH ECG database, this method can reach an accuracy of more than 92% under different compression ratios (2, 4, 8 and 16). Simulation experiments based on data from the PhysioNet/CinC Challenge 2011 database show that the accuracy of this method can reach above 83% under different compression ratios. In evaluation experiments using actual ECG signals, we show that this method can achieve good accuracy when the compression ratio is less than eight. The accuracy of this method needs to be further improved when the compression ratio is 16. When the compression ratio is less than 8 and a sparse matrix is not used as the measurement matrix, the method proposed in this paper can directly evaluate the quality of ECG signals after compression sampling without reconstruction. Compared with the signal quality evaluation algorithm in the uncompressed domain, the experimental results of the proposed method are highly competitive and, under a certain compression ratio, the amount of transmitted data can be reduced while maintaning accuracy. Meanwhile, the proposed method also provides a new idea for signal quality evaluation in the compressed domain.
On the role of excitation pulse duration on luminescence measurements
Authors: Allison Stephen W 
Published: March 2021

Abstract
Described here is an investigation into the effects of excitation pulse duration on the temporal character of luminescence of three characteristic thermographic phosphors: Mg4FGeO6:Mn, La2O2S:Eu, and YAG:Dy. Attention is first given to the build-up of the emission while the excitation pulse is on and its relation to temperature. Next, effects after pulse termination are addressed. For emission comprised of two or more characteristic decays, increasing the pulse duration will enhance the longer components relative to the shorter. For La2O2S:Eu, increasing the duration increases emission of successively longer-lived emitting states; and they display pronounced temperature dependence. For YAG:Dy, as excitation duration is increased, the main decay component used for thermometry is enhanced relative to two shorter components of less interest.
Facile aqueous synthesis of ZnInS quantum dots and its application for selective detection of Co2+ Ions

Published: March 2021

Abstract
The synthesis of ZnInS (ZIS) quantum dots (QDs) in aqueous medium using thioglycolic acid (TGA) and sodium citrate as dual capping agents has been reported. The as-synthesized ZIS QDs were water soluble, emitting at 512 nm and nearly spherical in shape with average particle size of 8.9 ± 1.4 nm. The as-synthesized ZIS QDs were tested for its fluorescence response against different metal ions and the results revealed that ZIS QDs were selectively quenched by Co2+ ions compared to other ions. The fluorescence sensing experiment showed that ZIS QDs has a linear response against the concentration of Co2+ ions (0.1–100 μM ) with the detection limit of 0.099 μM. Based on the transmission electron microscope and absorption spectroscopy analyzes, the fluorescence quenching is attributed to the formation of surface ligand-metal complex (TGA-Co2+ ions) which caused aggregation of the QDs. The present method explores the synthesis of zero-dimentional ZIS QDs and its potential in the selective detection of Co2+ ions in aqueous solution.
